[0012]
　Reference will now be described in detail preferred embodiments of the present disclosure. In the specification and the drawings, components having substantially the same function and structure are a repeated explanation thereof by referring to the figures.
[0013]

　<1. Embodiments of the present
　disclosure> [1.1. Summary
　Before describing in detail embodiments of the present disclosure, showing the events that led to the embodiment of the present disclosure an overview.
[0015]
　IoT-related research and development is actively carried out, it has attracted attention. In IoT, since it is necessary things lead to network, the wireless communication becomes more important technical theme. In 3GPP (Third Generation Partnership Project), such as MTC (Machine Type Communication) and NB-IoT (Narrow Band IoT), standardized communication method specifically for IoT terminal has been performed. The characteristics of these communication schemes, low power consumption, low cost, and a point that achieves a large coverage. Especially in low-cost terminal such as IoT terminal, since the low power consumption communication becomes very important, is expected to further enhancement in the future.
[0016]
　Representative examples of Low cost terminals include wearable devices. The wearable devices, low power consumption, highly reliable communication, high-capacity communication is required sometimes. In order to cover such use cases, standardization of the 3GPP FeD2D (Further enhancement D2D) was launched in 2016. Wearable device, since existing around the user himself by using the relay communication using the user terminal, such as a smart phone, to shorten the communication distance to be able to realize a highly reliable communication with low power consumption Become. In the following description, like wearable devices and IoT terminals communicating with the relay terminal it is also referred to as "remote terminal".
[0017]
　Figure 1 is an explanatory diagram showing an example of a relay communication using the relay terminal for wearable devices. 1 shows a base station 100, a relay terminal 200, a remote terminal 300, which is shown. Relay terminal 200 such as the user's smart phone is assumed, the remote terminal 300 wearable devices are contemplated. While performing communication based on the relay terminal 200 is the base station 100, for example, LTE (Long Term Evolution) and LTE subsequent communications standards, and communicates with the remote terminals 300 and side links. Remote terminal 300 communicates with the base station 100 via the relay terminals 200. Also, the remote terminal 300 can also communicate directly with base station 100.
[0018]
　In such relay communications for wearable terminal, guarantee the communication quality of the End-to end The between the base station and the remote terminal (QoS) is important, it is necessary to establish a reliable communication path. Also, the remote terminal because the wearable terminal is assumed, a low cost in a simple, low power consumption of the communication is determined. To achieve these requirements, implementation of the following items are required.
[0019]
　(Quick improvement of communication)
　in the side links, closed-loop feedback communication to perform such a retransmission far has not been performed. Therefore for QoS and highly reliable communication realization, support functions such as link adaptation and HARQ (Hybrid Automatic repeat-request) is obtained.
[0020]
　(Low power consumption)
　in the relay communication for wearable devices, power control and DRX (Discontinuous Reception) low power consumption, such as are required.
[0021]
　(Service continuity)
　in the relay communication for wearable devices, since the link quality changes dynamically, optimizing the handover and the path switching is required in order to ensure the continuity of service.
[0022]
　In the relay communication such for wearable devices, it is necessary to cover the various operations environment. Figure 2 is an explanatory diagram showing an example of a communication environment assumed in the relay communication for wearable devices. This assumes the two Short range Communication environment and Wide range Communication environment. Say wearable device, although cases the user holds the terminal is assumed (Short range communication), need not necessarily be limited to situations where the user is wearing the wearable device is technically. In other words, even in an environment such as not wearing a terminal, such relay communication itself is feasible. Therefore, not Short range Communication only, Wide range Communication is also desired to be supported by using a relay as well.
[0023]
　Another as a characteristic point in the operating environment include traffic. Terminal is assumed as a remote terminal, for example, from those which require high data rates, while others communicate very small amount of data packets, such as car keys unlocked necessary variations of a wide range of traffic is supported there is.
[0024]
　From the above, FeD2D for various Deployment scenarios, it is necessary to communicate the variation of the wide range of traffic volume efficiently. That is, the operation status of the relay communication, it is desirable that appropriate communication is provided.
[0025]
　For example, the side links in a relay communication, link adaptation and retransmission control using the feedback to ensure QoS and reliability is required. However, for example, the communication distance is very close, with are stable situation, when communicating the very small amount of the packet is not necessarily such a link adaptation and retransmission control'd may need.
[0026]
　Relay communication using the relay base station is standardized by 3GPP ever. However, different from a relay communication has been standardized, a case where the present embodiment is assumed. Shows the main differences below.
[0027]
　First, although the relay station is a fixed relay terminal has a mobility function. Furthermore, the relay base station is owned by the operator, performs the operation with equal rights and the base station, the relay terminal is owned by a user, authority as infrastructure is limited from the relay base station. Further, the relay terminal is usually considered to be carried out the operation under the control of the base station.
[0028]
　The communication in the relay base station, the user such as a smart phone is assumed portable terminal owned, communication in the relay terminal, MTC terminal to smartphones from NB-IoT terminal, support various communications traffic There is a need to.
[0029]
　Further, while the terminal Deployment kicking the relay base station is uniformly distributed within the coverage, the use case of wearable relay terminal, in the case of short-range communication that is wearing a wearable device and Deployment of the others are categorized. It is characterized by a remote terminal Deployment, very different from the Deployment of the relay base station.
[0030]
　In view of the aforementioned points, the wearable terminals and IoT handsets FeD2D communication, based on the 3GPP Rel-12 D2D, improved Sidelink to satisfy the following requirements: is obtained.
[0031]
　(Relay and the remote bandwidth support is different situations)
　for example MTC terminal is required six resource blocks, NB-IoT should support the case that it is only one resource block.
[0032]
　(QoS support)
　existing D2D communication, 3GPP Rel-12 D2D is because it was for public safety, was QoS support without communication using broadcast communication. In FeD2D communication, reliable and low-delay communication is required.
[0033]
　(Low power consumption)
　in FeD2D communication, lower power consumption is desired the remote terminal, both relay terminal.
[0034]
　(Single carrier property is kept)
　for the side link SC-FDMA (Single Carrier-Frequency Division Multiple Access) communication is carried out, in the FeD2D communication, multi-cluster communication want to avoid.
[0035]
　(To reduce the influence of the IBE)
　The D2D communication, compared to the cellular communication between a conventional base station and the terminal, the topology is different in transmission and reception. Since the transmitting and receiving terminals are mixed in the network, it is necessary to reduce the problem of IBE (In-Band Emission).
[0036]
　(Various support traffic)
　FeD2D communication, for communication for the commercial for wearable devices, it is necessary to support various traffic. FeD2D communication, for example, VoIP, video streaming, it is necessary to support such MTC traffic.
[0037]
　Accordingly the present disclosure shall, view of the foregoing, in FeD2D communication for remote terminal, intensively studied techniques for while achieving relay terminals and remote terminals power consumption, to realize the improvement in communication quality of FeD2D communication It was carried out. As a result, the present disclosure shall, as described below, devised in FeD2D communication for remote terminal, while reducing the relay terminal and the remote terminal power consumption, a technique that realizes improvement in communication quality of FeD2D communication This has led to the.

[0060]
　[1.3. Operation Example]
　First, a description will be given resources used by FeD2D communication in the present embodiment. In FeD2D communication in the present embodiment, a plurality of sub-resource pools are used configured in a resource pool. That set of sub resource pool is a resource pool. Sub resource pool may be set as the minimum supportable bandwidth at a particular terminal category. For example, in FeD2D system, 6-RB for MTC terminal (Physical Resource Block: 1RB = 180khz ) and, at least support 1RB of NB-IoT for terminal. Of course, the sub resource pool other than the above may be set. For example, in V2X (vehicle-vehicle-road-vehicle communication) system, for example, the value of the minimum supportable bandwidth V2X for terminals (e.g., 50 RB) may be set. Although description will be made of FeD2D communication in this embodiment may be applied to FeD2D other than the communication system such as V2X.
[0061]
　Resource pools and sub resource pool is constructed of a part of the Licensed band '. Resource pools and sub resource pool is generally the bandwidth of the uplink is allocated. The resource pool and sub resource pool may be configured with Unlicensed band '.
[0062]
　Sub resource pool may take a hierarchical structure. For example, the sub resource pool B is a subset of the sub-resource pools A, sub-resource pool A may be a subset of the resource pool. In the example of the MTC terminal and NB-IoT terminal, NB-IoT sub resource pool B of 1RB for terminal are a subset of the sub-resource pool A of 6RB for MTC terminal, the sub resource pool A is the resource pool it is a subset.
[0063]
　Resource pool, the sub-resource pools group, each sub-resource pool may be changed resource allocation assignment policies. For example the sub resource pool group 1 set Mode 1 communications, Mode 2 communication may be set in the sub resource pool Group 2.
[0064]
　6 to 9 are explanatory views showing a configuration example of a sub resource pool. Figure 6 shows an example of a resource pool that contains the sub resource pool 6RB four MTC for terminals (Sub_RP_MTC_0 ~ 4). Figure 7 shows an example of a resource pool that contains the sub resource pool 1RB four NB-IoT for terminals (Sub_RP_NBIoT_0 ~ 3).
[0065]
　Figure 8 is a sub-resource pools 6RB three MTC's terminal (Sub_RP_MTC_0,1,3), an example of six NB-IoT handsets sub resource pools 1RB (Sub_RP_NBIoT_0 ~ 5) containing the resource pool shows. Sub resource pool of NB-IoT for terminal is set to one of the sub-resource pools for MTC terminal. That is, the sub resource pool for MTC terminals are hierarchically shows an example of setting the sub resource pool of NB-IoT for terminal.
[0066]
　Figure 9 shows a sub-resource pools 6RB three MTC for terminals (Sub_RP_MTC_0 ~ 2), an example of six NB-IoT handsets sub resource pools 1RB (Sub_RP_NBIoT_0 ~ 5) containing the resource pool there. That is, the example in which the sub-resource pools for MTC terminal, and a sub resource pools NB-IoT for terminal were set independently.
[0067]
　In this embodiment, side links communicates side links from the relay terminal 200 to remote terminal 300 - Downlink (SL-DL), side links the side link communication from a remote terminal 300 to the relay terminal 200 - uplink (SL and the UL) is referred to as a communication. Resource pools and sub resource pool, from the perspective of the remote terminal, and a sub resource pools for the sub resource pool and SL-UL for SL-DL may be set independently. When set independently, may be set in FDD, it may be set by the TDD. Anchor sub resource pool described below is a sub resource pool for at least SL-DL.
[0068]
　Quick - downlink and side links - the uplink is determined by the base station 100 or relay terminal 200 is set in the remote terminal 300 SL-RRC signaling or MIB-SL (Master Information Block-Sidelink).
[0069]
　Quick - downlink and side links - the uplink may be set for each resource pool may be set for each sub-resource pool group. Further, side links - downlink and side links - the uplink may be set for each sub-resource pools.
[0070]
　Side links - downlink or side link - for each uplink, may be changed resource allocation policy. For example, side links - Mode 1 communication is used for the downlink, side links - may Mode 2 communication is used for the uplink.
[0071]
　When a plurality of sub-resource pool resource pool is allocated, the remote terminal 300 must monitor multiple sub resource pool is not efficient. However, raster each sub resource pool, in the method like finding the resources allocated to it, there is a possibility that remote terminal 300 miss receive opportunity, the power consumption of the remote terminal 300 also increases.
[0072]
　In this embodiment, it defines a sub resource pool of a plurality of sub-resource pools in the resource pool as an anchor sub resource pool.
[0073]
　Anchor sub resource pool may be one set for each size in the frequency direction of the sub resource pool. For example the A group of the sub-resource pool 6-RB, when the B group of the sub-resource pool 1RB coexist in the resource pool, the anchor sub resource pool be one set for each group good.
[0074]
　When the anchor sub resource pool is configured for the remote terminal 300, the remote terminal 300, all or any one or more of the monitors synchronizing signals and system information and control information in the anchor sub resource pool (control channel) to. That is, the remote terminal 300, the anchor sub resource sub-resource pools than pool may not monitor the monitored information anchor sub resource pool. Wherein the synchronization signal is a SLSS (Sidelink Synchronization Signal), the system information may include PSBCH (Physical Sidelink Broadcast Channel) and SCI (Sidelink Control Informaiton).
[0075]
　The anchor sub resource pool, the resource pool is set for the control region (Control) and the data area (Data), the sub resource pool than the anchor sub resource pool may be only resource pool is set to the data area .
[0076]
　Control information in the anchor sub resource pool may include allocation information of data of the data or other sub resource pool of the anchor sub resource pool. In that case, the allocation information may include information indicating a sub resource pool data is assigned.
[0077]
　The sub resource pool data is assigned, may be determined implicitly with string resources that the control information is detected. In that case, there is no need to information indicating a sub resource pool data is allocated to notify explicitly
[0078]
　Set position of the anchor sub resource pool may be fixed in advance, by means of RRC signaling or the like from the base station 100 may be notified with the resource pool or a sub resource pool configuration information. Anchor Subresource example transmission processing unit 151 for notifying the setting position of the pool may be performed under the control of the control section 153 original state. For example, the sub-resource pools most frequency is higher position within each group of sub resource pool may be set as the anchor sub resource pool in the respective groups of sub resource pool. Position information of the sub-resource pool may be notified as the number of sub-resources pool from the base station 100, top, or may be notified lowermost, as frequency direction directional information such as the center.
[0079]
　In the side links communicating using Unlicensed band ', only the anchor sub resource pool may be provided with Licensed band' from the base station 100.
[0080]
　10 to 13 are explanatory views showing an example of setting of the anchor sub resource pool. Figure 10 shows an example of a resource pool that contains the sub resource pool 6RB four MTC for terminals (Sub_RP_MTC_0 ~ 4). Figure 11 shows an example of a resource pool that contains the sub resource pool 1RB four NB-IoT for terminals (Sub_RP_NBIoT_0 ~ 3). In any case, for the MTC terminal, the sub-resource pool in the highest frequency position in the respective groups of sub resource pool of NB-IoT friendly terminal is set as the anchor sub resource pool 401 and 411.
[0081]
　Figure 12 is a sub-resource pools 6RB three MTC's terminal (Sub_RP_MTC_0,1,3), an example of six NB-IoT handsets sub resource pools 1RB (Sub_RP_NBIoT_0 ~ 5) containing the resource pool shows. Sub resource pool of NB-IoT for terminal is set to one of the sub-resource pools for MTC terminal. That is, the sub resource pool for MTC terminals are hierarchically shows an example of setting the sub resource pool of NB-IoT for terminal. Again, for the MTC terminal, sub-resource pools most frequency is higher position within each group of sub-resource pools NB-IoT friendly terminal is set as the anchor sub resource pool 401 and 411.
[0082]
　Anchor sub resource pool may be set independently, or may be superimposed on either the anchor sub resource pool. However, in this case, it is superimposed on a larger size of the frequency direction of the anchor sub resource pool. 13, the anchor sub resource pool 401 in the sub resource pool 6RB for MTC terminal, showing an example of anchor sub resource pool 411 is set in the NB-IoT for terminal. Anchor sub resource pool 401 of MTC's terminal is implemented using a region of the sub-resource pools, except for the anchor sub resource pool 411 of NB-IoT for terminal.
[0083]
　(Method of assigning resource pool)
　subsequently be described by way of three examples how to assign resource pools. Figure 14 is an explanatory diagram showing an overview of the allocation method of resource pools.
[0084]
　(1. base station allocates all)
　shows an example in which first base station 100 to implement the allocation of resource pools and sub resource pool relay terminal 200 and remote terminal 300. In this case, the allocation of resource pools and sub resource pool with the base station 100 the RRC signaling, for example.
[0085]
　The base station 100 notifies the information about the information about the resource pools and sub resource pool to the relay terminal 200 and remote terminal 300. Notification of information on the information about the resource pools and sub resource pool, for example, the transmission processing unit 151 may be implemented in the control of the control section 153 original state.

However, as can the initial communication between the relay terminal 200 and remote terminal 300, the base station 100, of the sub resource pool, sets the anchor sub resource pool relay terminal 200 and remote terminal 300.
[0090]
　Setting of the anchor sub resource pool, for example, pre-set (preconfiguration Figure) information may be used to relay terminal 200 and remote terminal 300. For example, the relay terminal 200 and the remote terminal 300 is used in the configured resources pooled from the base station 100, the sub-resource pools on the frequency to most as an anchor sub resource pool. Bandwidth of the sub resource pool in this case may be one resource block is notified as the allocation information of the resource pool may be used minimum sub resource pool bandwidth information. Since the anchor sub resource pool is a critical resource, it is desirable to set to reduce the IBE. Therefore, anchor sub resource pool may be configured to be set to the center frequency in the resource pool. The relay terminal 200 and the remote terminal 300 may identify the anchor sub resource pool from the resource block numbers bandwidth information and anchor sub resource pool resource pool.
[0091]
　The setting of the anchor sub resource pool, for example, information set by the base station 100 to the relay terminal 200 may be used. The relay terminal 200 may notify the information set from the base station 100 to remote terminal 300. The relay terminal 200 may notify the information of the relative position of the anchor sub resource pool in the resource pool.
[0092]
　Further, the relay terminal 200 and remote terminal 300 may locate the anchor sub resource pool by performing blind decoding.

[0094]
　Relay terminal 200 may report the information of the non-anchor sub resource pool that is not used by the base station 100. The base station 100 can allocate the sub resource pool that is not used by another of the relay terminal 200.
[0095]
　Relay terminal 200, a channel utilization of the non-anchor sub resource pool is calculated, and resources than a predetermined threshold when it is determined to be used, to implement the sub-channel resource addition request to the base station 100. Relay terminal 200, the conditions for implementing the resource addition request, in addition to the channel occupancy may be used BSR (Buffer status report). BSR is not per each of the terminals may be used Aggregated BSR obtained by aggregating the BSR remote terminals 300 of the relay terminal 200. Further, the relay terminal 200 may measure the channel utilization for each resource pool. The information contained in the resource addition request, channel utilization information request sub-resource pools group information, there can be BSR like. Base station 100, in response to the additional request from the relay terminal 200, to perform additional allocation of resource pool or a sub resource pool.
[0096]

In this case, the communication for the allocation of resource pool may even LTE Sidelink, other Non-3GPP communication may be (wireless LAN, Bluetooth (registered trademark), etc.).
[0098]
　(Anchor sub resource configuration in the pool)
　Next, the configuration of the anchor sub resource pool. Anchor sub resource pool, PSCCH (Physical Sidelink Control Channel) , PSSCH (Physical Sidelink Shared Channel), PSSS (Physical Sidelink Synchronization Signal), PSBCH (Physical Sidelink Shared Broadcast Channel), may include PSDCH (Physical Sidelink Discovery Channel).
[0099]

[0100]
　Frequency hopping flag is information on whether or not to perform frequency hopping, when performing frequency hopping (frequency hopping within a sub resource pool) Intra Sub-RP FH, Inter same Sub-RP FH (between the same sub-resource pools frequency hopping) of any of inter different sub-RP FH (frequency hopping between different sub-resource pool) can be set.
[0101]
　Resource block assignment is resource allocation information PSSCH, is information for performing the resource allocation in the anchor sub resource pool and non-anchor sub resource pool. If frequency hopping is adapted, it may include information about the frequency hopping.
[0102]
　TRP (Time resource pattern) is a resource allocation pattern information to be used when carrying out repeatedly a plurality of times a particular resource allocation. TRP is notified as the frequency allocation information in the frequency and time directions. If a set of PSCCH and PSSCH was defined as RAP (Resource allocation period), may be set one TRP in RAP, it may be repeated assigned multiple TRP in one RAP.
[0103]
　Resource scheduling validity period, if you define RAP a pair of PSCCH and PSSCH, scheduled results PSCCH is information indicating an enabled until which time the future. As resource scheduling lifetime may be notified the information of the time axis may be the number PSSCH allocated in the future as an effective RAP number is set.
[0104]
　Flag indicating whether to send a PSSCH signals PSCCH resources, when straddling a plurality of RAP by the scheduling lifetime, whether flag information sending instead PSSCH in PSCCH resources that are no longer required transmission it is.
[0105]
　Resource allocation information ACK / NACK transmission, in response to reception possibility of data transmitted to the RAP, which is information for remote terminal 300 sends back a resource to the specified ACK / NACK. ACK / NACK allocated resource units for transmission is one resource pool block. ACK / NACK resources for transmission may be implemented allocated straddling several RAP one PSCCH. The resource allocation ACK / NACK transmission, SPS (Semi-Persistent scheduling) may be performed. In this case, by using the RRC signaling from the base station 100 determines a resource for transmitting ACK / NACK to the relay terminal 200 and remote terminal 300. Remote terminal 300, to activate using the Activation indicator of PSCCH the configured ACK / NACK resources for transmission.
[0106]
　Remote terminal 300 in some cases the relay terminal 200, performs resource allocation request SL-UL communication. At this time, the remote terminal 300 transmits the SL-UL-request as a resource allocation request. Resources used SL-UL-request can be set similarly to the resource allocation information for transmitting ACK / NACK.
[0107]
　In PSBCH, it may include a MIB-SL (Master Information Block-Sidelink) SBCCH (Sidelink Broadcast Control Channel), such as contents. MIB-SL may be transmitted for each RP, it may be transmitted for each sub-resource pool. MIB-SL, the side link bandwidth information, Sidelink frame number, Sidelink Subframe number, Tdd-configuration, Relay ID, PSSCH DMRS format, may include setting information of the SL-DL or SL-UL. PSSCH DMRS format indicates the DMRS format used in PSSCH.
[0108]
　(Control and Data METHOD assignment)
　Subsequently, explanation of the structure of the Control and Data in the sub resource pool. In the present embodiment, PSCCH as Control, it is assumed PSSCH as Data.
[0109]
　Control and Data is, (1) TDM (Time Division Multiplexing), (2) FDM (Frequency Division Multiplexing), (3) TDM + FDM, can be considered configuration pattern of three ways. Incidentally, combination of (1) to (3) may be used within the same resource pool. Further, as the information necessary for assignment of the (1) ~ (3), BSR, traffic type, information such as priority information may be notified to the relay terminal 200 from the remote terminal 300. The configuration information of the base station 100 (1) to (3) may be set when allocating sub resource pool or resource pool. Further, the (1) to (3) may be varied depending on the channel that transmits the like Communication and Discovery.
[0110]
　(1) TDM
　illustrating an example of setting PSCCH in the case of TDM. Figure 21 is an explanatory diagram for explaining a setting example of PSCCH in the case of TDM, examples and Control area 402 and the Data area 403 is set in the TDM is shown. Reference numeral 401 is an anchor sub resource pool. Since the bandwidth in FeD2D is variable may not be enough frequency resources. Therefore, the conventional symbol-level Control channels such as LTE without creating, PSCCH is to assign a resource block to one user.
[0111]
　When sending Control only in the anchor sub resource pool, Control area to the anchor sub resource pool may be set. Figure 15 is an explanatory diagram showing an example of Control region is set to anchor the sub resource pool. In this case, Control area 402 is set in a TDM anchor sub resource pool. Also in Figure 15, the anchor sub resource pools, which shows how the Data area 403 straddling and another sub-resource pool is set.
[0112]
　The relay terminal 200 and remote terminal 300, performs the communication using the anchor sub resource pool, when the frequency is insufficient, the relay terminal 200 is able to add non-anchor sub resource pool resource allocation target. By assigning this manner, always a continuous frequency relay terminal 200 is to transmit. This Single carrier property of SC-FDMA of the relay terminal is maintained, it is possible to suppress the increase of the PAPR (Peak-to-Average Power Ratio).
[0113]
　In this case, the relay terminal 200 and the remote terminal 300 may use a resource that is not used by PSCCH area for the Data transmission. PSCCH areas, from the base station 100 or relay terminal 200 is notified as a sub resource pool or resource pool configuration information.
[0114]
　Figure 16 is an explanatory diagram showing an example of Control region is set to anchor the sub resource pool. In the example of FIG. 16, eight control information to the Control area 451 is set, according to the eight control information, Data is transmitted in the anchor sub resource pools and sub resource pool.
[0115]
　When sending Control only in the anchor sub resource pool, the remote terminal 300 may assign one sub resource pool per terminal per RAP. Figure 17 is an explanatory view showing an example in which one sub-resource pool per terminal per RAP is assigned. Figure 17 is, Control area 402 in anchor sub resource pool is shown an example that is set by TDM. Also in Figure 17, the anchor sub resource pools, which shows how the Data area 403 straddling and another sub-resource pool is set. And in this example, one sub-resource pool per terminal per RAP is configured for Data.
[0116]
　If one of the sub resource pool per terminal per RAP is assigned, the assignment of the remote terminal 300 of the maximum number of sub-resource pools are performed at the same time. That is, if four is the number of sub-resource pool allocation of four remote terminal 300 at the maximum is performed. Thus resource allocation in the frequency direction of a resource block becomes unnecessary. Incidentally, when the number of remote terminals is larger than the number of sub-resource pools, to implement the scheduling for the next subsequent RAP. In this case, allocation of two or more terminals in each sub-resource pool, corresponding PSCCH, may be performed assignment is designed to be changed in the time axis direction.
[0117]
　In RAP of the last Data resource block slots, resources for transmission ACK / NACK are assigned in PSCCH resource allocation. ACK / NACK may be sent using one resource block. The ACK / NACK may be transmitted with a plurality of remote terminals partial multiplexed in one resource block. In this case, code multiplexing may be implemented by a plurality of remote terminals 300. Code assignment at this time, allocated in PSCCH is performed. ACK / NACK resource may be allocated to the last subframe of RAP of each sub-resource pool. Figure 18 is an explanatory diagram showing an example of allocation of ACK / NACK resources is an explanatory view showing an example in which ACK / NACK resources 404 are allocated to the last subframe of RAP of each sub-resource pool. Also, ACK / NACK resource may be assigned together to the last subframe of the RAP anchor sub resource pool. Figure 19 is an explanatory diagram showing an example of allocation of CK / NACK resources is an explanatory view showing an example in which ACK / NACK resources 404 are allocated together in the last subframe of the RAP anchor sub resource pool.
[0118]
　Then, the Control anchor sub resource pool and non-anchor sub resource pool relay terminal 200 will be described an example of a case of transmitting. Figure 20 is a relay terminal 200 Control channel anchor sub resource pool and non-anchor sub resource pool is an explanatory diagram showing an example of transmitting. FIG 20, Master Control region 405 to the anchor sub resource pool is shown an example that is set by TDM. Also in Figure 20 is shown an example of Control region 402 to the non-anchor sub resource pool has been set. Also in Figure 20, the anchor sub resource pools, which shows how the different sub-resource pools and each Data area 403 is set.
[0119]
　In this example, allocation sub-resource pools remote terminals is performed in the Control regions in the anchor sub resource pool. The Control regions in the anchor sub resource pool is referred to as a Master Control channel. Each remote terminal 300 in the sub resource pool specified by Master Control channel, decodes the Control channel. Thus, each remote terminal 300 identifies its own data area. Master Control channel and Control channel is set at the time of allocation of resource pool or a sub resource pool.
[0120]
　If included scheduling scope information or TRP information in PSCCH, scheduling is performed until the next RAP region. For example, looking at the assignments 8 in FIG. 16, the data area is performed scheduling so that is set across RAP.
[0121]
　When instructing the plurality of RAP in one PSCCH, sometimes PSCCH resources are wasted. Therefore, for effective utilization of resources may schedule PSSCH in PSCCH resources does not transmit PSCCH. The relay terminal 200 is notified by PSCCH whether flag scheduling PSSCH in PSCCH resources does not transmit PSCCH to the remote terminal 300.
[0122]
　(2) FDM
　will be described an example of setting PSCCH in the case of FDM. Figure 22 is an explanatory diagram for explaining a setting example of PSCCH in the case of FDM, examples and Control area 402 and the Data area 403 is set in FDM is illustrated. Reference numeral 401 is an anchor sub resource pool. For FDM, Control channel may be arranged only on the anchor sub resource pool may be located in all the sub resource pool. If Control channels are arranged in all the sub resource pool to introduce a Master Control channel similar to the above TDM.
[0123]
　(3) TDM + FDM
　will be described an example of setting PSCCH of combining the TDM and FDM. Figure 23 is an explanatory diagram for explaining a setting example of PSCCH of combining the TDM and FDM, examples and Control area 402 and the Data area 403 is set in the TDM and FDM are shown.
[0124]
　If a combination of the TDM and FDM, by applying a limit in the time domain for FDM allocation, it is possible to reduce the load on the decoding of the Control Channel in a remote terminal 300. Time division of a TDM is set by the base station 100 or relay terminal 200. Also, TDM time axis may be set as a DRX (Discontinuous Reception).
[0125]
　If a combination of the TDM and FDM, similarly to the case of TDM or FDM, Control channel may be arranged only on the anchor sub resource pool may be located in all the sub resource pool. If Control channels are arranged in all the sub resource pools, as with TDM is Master Control channel is introduced.
[0126]
　Thus, the base station 100 or relay terminal 200 according to an embodiment of the present disclosure, it is possible to set the resources for inter-device communication between the relay terminal 200 and remote terminal 300. In the present embodiment, it is composed a plurality of sub-resource pools in the resource pool, further defines the one of them as an anchor sub resource pool. The anchor sub resource pool, control information directed to the remote terminal 300 is stored, the remote terminal 300, by monitoring the anchor sub resource pool can be monitored efficiently control information.
[0127]
