Technical field
[0001]
The present invention relates to the field of communications, in particular to a method and device for determining resources, and a communication system.
Background technique
[0002]
In recent years, wireless communication technology has developed rapidly, and the standardization of the 3rd Generation Partnership Project (3GPP) has been developed to Rel.15 (version 15). Starting from Rel. 13, based on the consideration of further capacity expansion, Long Term Evolution (LTE) technology began to use unlicensed frequency bands for transmission. Starting from Rel.14, enhanced licensed spectrum assisted access (eLAA) has been introduced, and an uplink transmission mechanism of unlicensed frequency bands has been introduced in eLAA. At the same time, in order to ensure coexistence with other technologies working in unlicensed frequency bands, advanced The channel contention access mechanism of Listen-Before-Talk.
[0003]
It should be noted that the above introduction to the technical background is only set forth to facilitate a clear and complete description of the technical solutions of the present invention and to facilitate the understanding of those skilled in the art. It should not be considered that the above technical solutions are well-known to those skilled in the art just because these solutions are described in the background art part of the present invention.
[0004]
Summary of the invention
[0005]
eLAA data transmission is carried out under the framework of carrier aggregation, that is, terminal equipment first accesses the network through a licensed frequency band, and the network equipment allocates unlicensed frequency band carriers to the terminal equipment. Each carrier requires a scheduling control signaling to schedule the carrier. In the LTE system, the maximum bandwidth of a carrier is 20MHz.
[0006]
In future wireless communication systems, such as 5G and New Radio (NR) systems, the maximum channel bandwidth can reach 100 MHz (that is, large bandwidth). In the current discussion, NR broadband transmission technology can also be applied to unlicensed frequency bands, but the inventor found that there is currently no method for scheduling data transmission resources when using large bandwidth transmission on a frequency carrier in the NR unlicensed frequency band.

The embodiments of the present invention provide a resource scheduling indication method, device, and communication system, which achieve the purpose of being suitable for broadband transmission and effectively improving the utilization rate of wireless resources on the basis of ensuring OSB/PSD.
[0055]
It should be noted that the embodiment of the present invention takes an unlicensed frequency band as an example for description, but the present invention is not limited to this, and the present invention is also applicable to other scenarios where similar problems exist.
[0056]
The embodiments of the present invention will be described below in conjunction with the drawings.
[0057]
Example 1
[0058]
Fig. 2 is a flow chart of the resource indication method of this embodiment 1, which is applied to the terminal device side. As shown in Figure 2, the method includes:
[0059]
Step 201: The terminal device receives resource scheduling indication information for indicating uplink transmission resources sent by the network device. The uplink transmission resource includes at least one resource scheduling unit; where one resource scheduling unit is an integer (M1) scheduled bandwidth A collection of subcarrier clusters spaced in the frequency domain in a unit;
[0060]
Step 202: The terminal device sends uplink data on the uplink transmission resource.
[0061]
In this embodiment, in the case of broadband transmission, the size of the transmission bandwidth should be an integer multiple of 20 MHz under the condition that no other transmission technologies can coexist. The network device can configure or indicate the transmission bandwidth of the terminal device in units of bandwidth.
[0062]
In this embodiment, the integer number of scheduled bandwidth units are frequency domain resources on one frequency carrier of the unlicensed band; the frequency domain width of the scheduled bandwidth unit is equal to the first value, for example, the first value is 20 MHz, or 40MHz, or 80MHz, or 100MHz; or, the first value can also be expressed in the form of the number of resource blocks (RB), the number of resource blocks included in the scheduled bandwidth unit is equal to the first value, and the first value is an integer number The number of resource blocks included in the 20MHz bandwidth resource. The specific quantity value is related to the sub-carrier spacing. For example, when the sub-carrier spacing is 15kHz, the 20MHz bandwidth contains 106 RBs, and the bandwidth unit contains 106 RBs (one RB contains 12 subcarriers), and 40MHz (equivalent to 2 subcarriers) The 20MHz) bandwidth includes 216 RBs, and the bandwidth unit includes 216 RBs (one RB includes 12 subcarriers), etc., and no examples are given here.
[0063]
In this embodiment, the first value of the frequency domain width of the bandwidth unit may be a default value. For example, the frequency domain width of the bandwidth unit may be predefined by network equipment and terminal equipment, or the frequency of the bandwidth unit The domain width may be configured by the network equipment through high-level signaling, or the bandwidth unit may be indicated to the terminal equipment after being configured by the network equipment through high-level signaling. This embodiment is not limited to this.
[0064]
In this embodiment, the network device can pre-configure the transmission bandwidth for the terminal device. The transmission bandwidth can be used for the terminal device to send uplink data, but not necessarily all is actually used to send the uplink data. The network device can indicate the terminal device in the transmission bandwidth. Actually scheduled scheduling bandwidth, and allocate uplink transmission resources for sending uplink data to the terminal device on the scheduling bandwidth. The above-mentioned transmission bandwidth and scheduling bandwidth are respectively explained below.
[0065]
In this embodiment, the transmission bandwidth includes one or more bandwidth units configured by the network device for the terminal device on a frequency carrier, where the frequency carrier may be an unlicensed band frequency, but this embodiment does not take this as limit.
[0066]
In this embodiment, before step 201, the method may further include: (not shown) S1, the terminal device receives resource configuration information sent by the network device, and the resource configuration information is used to indicate that it is on a frequency carrier One or more (M2) bandwidth units configured by the terminal device, the resource configuration information may include the position and/or size information of the configured M2 bandwidth units, for example, the first value of the frequency domain width of the bandwidth unit is the default value When the location information includes the sequence number of the first and/or last resource block included in the configured bandwidth unit, and optionally, it may also include size information. For example, the size information may be the number of configured bandwidth units M2, Or the number of resource blocks included in the configured M2 bandwidth units; for example, when the first value of the frequency domain width of the bandwidth unit is an optional value, the resource configuration information may also include each bandwidth of the configured M2 bandwidth units The sequence number of the first and/or last resource block of the unit, and the number of resource blocks it contains (the first value), where the number of resource blocks contained in each bandwidth unit of the configured M2 bandwidth units can be The same or different, and this embodiment is not limited thereto.
[0067]
In this embodiment, the terminal device obtains the resource configuration information through high-level configuration signaling or broadcast information sent by the network device. For example, the resource configuration information may be included in the high-level configuration signaling or broadcast sent by the network device to the terminal device. In the information, the broadcast information can be carried in the master information block (MIB) or the system information block (SIB), or the resource configuration information can be implicitly indicated by the information carried by the broadcast information (for example, it can be based on the information obtained through the system information). The frequency carrier implicitly determines the number of resource blocks included in the bandwidth unit, but it is not limited to this).
[0068]
In this embodiment, in one implementation, the scheduling bandwidth may be equal to the transmission bandwidth, the scheduling bandwidth is equal to an integer (M1) scheduled bandwidth units, and the transmission bandwidth is equal to one or more (M2) bandwidth units configured, namely M1 is equal to M2, and the configured M2 bandwidth units are the scheduled M1 bandwidth units. In other words, after the terminal device receives the resource configuration information, it can determine the scheduled bandwidth units according to the determined M2 bandwidth units indicated by the resource configuration information M1 bandwidth units, the two are the same.
[0069]
In this embodiment, in an implementation, the scheduling bandwidth may be less than or equal to the transmission bandwidth, the scheduling bandwidth is equal to an integer (M1) scheduled bandwidth units, and the transmission bandwidth is equal to one or more (M2) bandwidth units configured. , That is, M1 is less than or equal to M2, and the configured M2 bandwidth units include the scheduled M1 bandwidth units.
[0070]
In this embodiment, the method may further include: (not shown) S2, the terminal device receives bandwidth unit indication information sent by the network device, where the bandwidth unit indication information is used to indicate one or more bandwidth units of the configuration The integer number of scheduled bandwidth units, that is, the bandwidth unit indication information is used to indicate which of the configured M2 bandwidth units are the scheduled M1 bandwidth units.
[0071]
In an embodiment, the bandwidth unit indication information may include the index of the integer number of scheduled bandwidth units, or the bandwidth unit indication information is a bitmap corresponding to the configured number of M2 bandwidth units, and each bit indication corresponds to Whether the configured bandwidth unit of is a scheduled bandwidth unit, for example, the bandwidth unit indication information includes M1 indexes, respectively identifying the scheduled M1 bandwidth units, or the bandwidth unit indication information is M2 bits, and each bit corresponds to a configuration When the bit value is 0, it means that the bandwidth unit of the configuration is not a scheduled bandwidth unit; when the bit value is 1, it means that the bandwidth unit of the configuration is a scheduled bandwidth unit, that is, among the M2 bits, The number of 1 is M1, and 0 and 1 are taken as an example for illustration above, but this embodiment is not limited by this.
[0072]
In another embodiment, in order to indicate the scheduled bandwidth unit more conveniently, the configured M2 bandwidth units can also be divided into at least one frequency bandwidth, and each frequency bandwidth includes at least one configured bandwidth unit, and the bandwidth unit indication information The frequency bandwidth index is used to indicate the scheduled bandwidth unit. In this embodiment, the resource configuration information further includes frequency bandwidth configuration information; the frequency bandwidth includes at least one configured bandwidth unit. In this embodiment, the configuration information of the frequency bandwidth includes the index value of the at least one configured bandwidth unit, and/or the number of the at least one configured bandwidth unit.
[0073]
For example, for the configured M2 bandwidth units, some or all of them are formed into M3 frequency bandwidths, and the M3 frequency bandwidths are uniquely identified by the index. For each frequency bandwidth, at least one configured bandwidth unit is included. The number of configured bandwidth units included in the frequency bandwidth may be the same or different. The configuration information of the M3 frequency bandwidths may be included in the resource configuration information, for each frequency bandwidth identified by the index, the configuration information of the frequency bandwidth includes the index value of at least one configured bandwidth unit contained in the frequency bandwidth, and /Or the number of the at least one configured bandwidth unit, optionally, may also include the index of the corresponding frequency bandwidth. In this implementation manner, the bandwidth unit indication information may include an index of the frequency bandwidth, thereby indicating that at least one configured bandwidth unit included in the frequency bandwidth identified by the index is a scheduled bandwidth unit. In this embodiment, the terminal device obtains the bandwidth unit indication through at least one of radio resource control (RRC) signaling, media access control (MAC) signaling, and physical layer control information sent by the network device information.
[0074]
In this embodiment, the frequency bandwidth and/or bandwidth unit may be a part of the bandwidth BWP defined in NR, or may be other defined bandwidth units, and this embodiment is not limited thereto.
[0075]
In this embodiment, the integer number of scheduled bandwidth units do not overlap with each other, that is, the integer number of scheduled bandwidth units do not include the same time-frequency resource.
[0076]
The above explains how to determine the integer number of scheduled bandwidth units, where both M1 and M2 are integers greater than or equal to 1, and M2 is greater than or equal to M1. The following describes how to indicate the scheduled uplink transmission resources in the integer number of scheduled bandwidth units .
[0077]
In this embodiment, since the one frequency carrier is an unlicensed band frequency, the integer bandwidth units scheduled on it are also frequency domain resources of the unlicensed band.
[0078]
In this embodiment, a resource scheduling unit is a collection of subcarrier clusters spaced in the frequency domain in an integer number of scheduled bandwidth units. The subcarrier cluster can be an RB or a collection of an integer number of subcarriers. The following is for convenience Description, a resource scheduling unit is called an interlace. The following describes the distribution form of the resource scheduling unit on an integer number of scheduled bandwidth units.
[0079]
In an embodiment, the integer number of scheduled bandwidth units includes at least two resource scheduling units (interlaces), and the frequency domain resources included in the integer number of scheduled bandwidth units belong to two subcarrier clusters with a first fixed interval between them. The same resource scheduling unit, that is, the two sub-carrier clusters that satisfy the first fixed value of the interval belong to the same interlace. In other words, the frequency of the sub-carrier cluster included in a resource scheduling unit in an integer number of scheduled bandwidth units The domain resources are evenly distributed at equal intervals, and the interval is equal to the first fixed value. Wherein, the resource scheduling units in the integer number of scheduled bandwidth units are identified by indexes, and the indexes of the at least two resource scheduling units are different, that is, each interlace is assigned an index that uniquely identifies the interlace.
[0080]
Fig. 3A is a schematic diagram of the distribution of resource scheduling units in this embodiment. As shown in Fig. 3A, the scheduled M1 bandwidth units contain a total of N1 subcarrier clusters and N2 resource scheduling units interlace, with indexes of 0 and 1, respectively. …, N2-1, the interval on the frequency domain resources contained in the M1 bandwidth units is the first fixed value, for example, the two subcarrier clusters of N2 belong to an interlace, that is, the subcarrier clusters contained in an interlace are in an integer number of scheduled bandwidth units The frequency domain resources are evenly spaced, and the interval is equal to the first fixed value N2, and the first fixed value is equal to the number of interlaces; the number of subcarrier clusters contained in each interlace in the N2 resource scheduling unit interlace can be the same or different For example the front one interlace contains subcarriers cluster, after one interlace comprises a subcarrier cluster; e.g. before or one interlace comprises subcarriers cluster after a interlace contains subcarriers clusters.
[0081]
For example, the 30kHz subcarrier interval in the 40MHz bandwidth includes two scheduled bandwidth units, namely M1=2, which contains 106 RBs, indexed from RB0 to RB106. If the subcarrier cluster is in RB units, then N1=106. A bandwidth unit contains 10 interlaces, that is, the first fixed value is 10, then the average interlace should contain 11 (106/10 rounded up) RBs, and the last 4 (10×11-106) interlaces Contains 10 RBs, that is, the first 6 interlaces contain 11 RBs, and the last 4 interlaces contain 10 RBs. Then the 11 RBs included in the first interlace are RB0, RB10, RB20, ... RB100, and the 10 RBs included in the 10th interlace are RB9, RB19, ... RB99.
[0082]
Or, calculate the average that each interlace should contain 10 (106/10 rounded down) RBs, the first 6 (106-10×10) interlaces can contain 11 RBs, that is, the last 4 interlaces contain 10 RBs, The first 6 interlaces contain 11 RBs. Then the 10 RBs included in the first interlace are RB0, RB10, RB20, ... RB100, and the 10 RBs included in the 10th interlace are RB9, RB19, ... RB99.
[0083]
In an embodiment, the sub-carrier cluster included in a resource scheduling unit belongs to a scheduled bandwidth unit, and each scheduled bandwidth unit includes at least two resource scheduling units (interlaces), and one of the scheduled bandwidth units includes The two subcarrier clusters with a second fixed interval on the frequency domain resources belong to the same resource scheduling unit. That is, in the scheduled bandwidth unit, the two sub-carrier clusters that meet the second fixed value of the interval belong to the same interlace. In other words, the sub-carrier cluster contained in a resource scheduling unit is in the frequency domain resource of a scheduled bandwidth unit The at least two resource scheduling units included in a scheduled bandwidth unit are identified by an index, and the indexes of the at least two resource scheduling units are different. That is, each interlace in a scheduled bandwidth unit is assigned an index that uniquely identifies the interlace in the scheduled bandwidth unit.
[0084]
Fig. 3B is a schematic diagram of the distribution of resource scheduling units in this embodiment. As shown in Fig. 3B, the scheduled M1 bandwidth units contain a total of N1 sub-carrier clusters, and the number of sub-carrier clusters contained in each bandwidth unit may be the same or different. The number of interlaces contained in each bandwidth unit can be the same or different. The following takes one bandwidth unit (the Qth) of the M1 bandwidth units as an example to illustrate the distribution of resource scheduling units in this bandwidth unit, and the distribution of resource scheduling units of other bandwidth units Similar to the Q-th bandwidth unit, it will not be repeated; for the Q-th bandwidth unit, it contains a total of N3 subcarrier clusters and N4 resource scheduling units interlace. The Q-th bandwidth unit contains the second frequency domain resource interval. A fixed value, for example, two subcarrier clusters of N4 belong to an interlace, that is, the subcarrier clusters contained in an interlace are evenly spaced on the frequency domain resources of the Qth bandwidth unit, and the interval is equal to the second fixed value, such as N4; number of subcarrier clusters N4 resource scheduling units interlace in each interlace contains may be the same, or different, for example the front one interlace contains subcarriers cluster, after one interlace comprises a subcarrier cluster; or for example before and after an interlace comprising subcarrier cluster, the interlace contains a subcarrier clusters. Among them, for each bandwidth unit, the interlace contained in it independently identifies the index in a bandwidth unit, for example, for bandwidth unit 0 in Figure 3B, it contains interlace 0, 1..., N40 (not shown), referring to Figure 3B Medium bandwidth unit 1, which contains interlace 0, 1..., N41 (not shown). The interlace with index 0 in bandwidth unit 0 only identifies the interlace in bandwidth unit 0, and the interlace with index 0 in bandwidth unit 1 only Identifies the interlace in the bandwidth unit 1.
[0085]
In this embodiment, the network device uses the above resource scheduling unit as the unit for allocating uplink transmission resources to the terminal device, that is, the uplink transmission resource includes at least one (X) resource scheduling unit, and X is greater than or equal to 1, the resource scheduling indication information It includes a resource allocation field used to indicate the uplink transmission resource, and the resource allocation field includes an index and/or quantity of the at least one (X) resource scheduling unit. The resource scheduling indication information may be carried by at least one control information.
[0086]
In the following, the resource scheduling unit distribution examples of FIGS. 3A and 3B are respectively taken as examples to illustrate specific implementations of resource scheduling indication information under different resource scheduling unit distribution examples.
