The embodiment of the present invention relates to the field of communication technology.
Background technique
[0002]
In the Long Term Evolution (LTE) enhanced Licensed Assisted Access (eLAA, enhanced Licensed Assisted Access), an uplink transmission mechanism of an unlicensed frequency band is introduced. In order to meet the requirements of Occupied Channel Bandwidth (OCB) and Power Spectrum Density (PSD), eLAA uses Interlace as the basic unit of uplink transmission resource allocation.
[0003]
Fig. 1 is an example diagram of an Interlace structure in a 20MHz bandwidth in LTE. For example, one Interlace is composed of 10 resource blocks (RB, Resource Block), and these 10 resource blocks are equally spaced in a 20 MHz bandwidth. For example, Interlace 0 is composed of RB0, RB10, RB20,..., RB90.
[0004]
A network device (for example, a base station) can allocate one or more Interlaces to the terminal device through uplink scheduling signaling for uplink data transmission of the terminal device. In addition, eLAA data transmission is carried out under the framework of carrier aggregation, that is, the terminal equipment first accesses the network equipment through the licensed frequency band, and the network equipment then allocates the carrier of the unlicensed frequency band to the terminal equipment. Each carrier requires a scheduling control signaling. To schedule the transmission on that carrier.
[0005]
In New Radio (NR, New Radio) Rel. 15, the unit of uplink and downlink resource allocation is a resource block group (RBG, Resource Block Group). According to the number of resource blocks contained in the carrier bandwidth, the number of resource blocks contained in the resource block group can be determined, in the range {2,4,8,16}; according to the frequency domain position of the bandwidth part (BWP, Bandwidth Part) in the carrier , You can calculate the number of RBGs included in part of the bandwidth.
[0006]

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.

[0066]
Figure 3 is an example diagram of BWP in NR Rel.15. As shown in FIG. 3, in a carrier with a resource block group size of 4 RBs, a partial bandwidth includes 51 RBs ranging from common RB14 to common RB64, and the partial bandwidth includes a total of 14 resource block groups. Among them, the first resource block group (RBG 0) includes 2 RBs, the last resource block group (RBG 13) includes 1 RB, and other resource block groups include 4 RBs.
[0067]
NR Rel.15 includes two uplink and downlink resource allocation methods (mode 0 and mode 1). Mode 0 indicates the RBG scheduling situation in the partial bandwidth (BWP) through a bitmap; Mode 1 indicates the start RBG and the number of RBGs among multiple consecutive RBGs that are scheduled through the resource indication value (RIV, Resource Indication Value) .
[0068]
In the 90bis meeting of 3GPP RAN4, NR-based access to unlicensed spectrum was agreed to support a single carrier frequency with a bandwidth of more than 20MHz (the bandwidth of a single carrier frequency includes multiple channel idle detection bandwidth units ).
[0069]
When using unlicensed spectrum to transmit data, in order to avoid interference, the sending device needs to perform channel idle detection, and only when the frequency band where the data is to be sent is detected as an idle state (that is, no other device occupies the spectrum to send data), the sending device Only then can data be sent in this frequency band; otherwise, the sending device cannot use this frequency spectrum to send data. Wherein, the channel idle detection bandwidth unit is, for example, a frequency domain unit for channel idle detection when the sending device uses unlicensed spectrum to transmit data. For example, it may be 20 MHz, or may also be an integer multiple of 20 MHz.
[0070]
Figure 4 is a schematic diagram of a channel idle detection bandwidth unit. Large-bandwidth transmission with a single carrier frequency bandwidth exceeding 20MHz can include two methods. As shown in Figure 4, when using mode 1, only when the channels of each channel idle detection bandwidth unit for scheduling data transmission are detected as idle, the scheduling bandwidth can transmit data; when using mode 2, it can be used in the channel Data is transmitted on one or more bandwidth units detected as idle. For example, if only part of the channels are idle, the bandwidth unit is detected as idle, then data is transmitted on these bandwidth units detected as idle.
[0071]
For the above two methods, in order to ensure that out-of-band radiation does not cause interference to adjacent frequency bands, it is necessary to reserve spaced bandwidth (or also called protection bandwidth) resources on both sides of the transmission bandwidth. And for method 2, because the bandwidth unit that can actually transmit data cannot be determined before the channel idle detection, it is necessary to set aside bandwidth resources on both sides of each bandwidth unit. However, network equipment and terminal equipment may have inconsistent understanding of whether these interval bandwidth resources are schedulable, and therefore cannot reach a consensus on spectrum resources, and cannot effectively improve resource utilization.
[0072]
The following will take the resource of the unlicensed frequency band as an example to describe the embodiment of the present invention, but the present invention is not limited thereto. For example, for the resource of the licensed frequency band, the embodiment of the present invention is still applicable.
[0073]
Example 1
[0074]
The embodiment of the present invention provides a method for determining a resource, which is described from the terminal device side. FIG. 5 is a schematic diagram of a method for determining a resource according to an embodiment of the present invention. As shown in FIG. 5, the method includes:
[0075]
501: A terminal device receives indication information sent by a network device, where the indication information is used to determine whether the interval bandwidth resource belongs to a scheduled bandwidth resource.
[0076]
502: The terminal device receives resource scheduling information sent by the network device; and
[0077]
503. The terminal device determines the size of the transmission block according to the indication information and the resource scheduling information.
[0078]
It is worth noting that Fig. 5 above only schematically illustrates the embodiment of the present invention, but the present invention is not limited to this. For example, the order of execution among various operations can be adjusted appropriately, and some other operations can be added or some operations can be reduced. Those skilled in the art can make appropriate modifications based on the foregoing content, and are not limited to the description of the foregoing FIG. 5.
[0079]
In an embodiment, the terminal device may also report capability information to the network device, the capability information at least indicating whether the terminal device has the ability to adjust the size of the scheduling bandwidth resource according to the channel idle detection result.
[0080]
For example, in the above method 2, the transmission bandwidth is adjusted immediately after channel detection, which has certain requirements on the processing capability of the UE. Therefore, the UE needs to include in the capability information reported to the base station whether the UE supports the capability information that the scheduling bandwidth changes according to the channel idle detection result.
[0081]
In an embodiment, the interval bandwidth resource may be one or more resource units between at least two bandwidth units configured in the partial bandwidth (BWP), or the interval bandwidth resource may be at least one or more resource units configured in the partial bandwidth (BWP). One or more resource units other than a bandwidth unit. The resource unit may be one or more resource blocks (RB), or one or more resource block groups (RBG), or one or more subcarriers; but the present invention is not limited thereto.
[0082]
The following first explains the situation of resource allocation. At least one bandwidth unit is configured in the partial bandwidth (BWP) configured for the terminal device (the following takes the subband as an example for description).
[0083]
In an embodiment, the partial bandwidth (BWP) is also configured with information indicating the start resource block and the number of resource blocks of the BWP, and the resource blocks in the BWP that do not belong to the bandwidth unit are used as interval bandwidth resources.
[0084]
For example, first configure the starting common RB of the BWP and the number of common RBs included, and then configure at least one bandwidth unit included in the BWP. RBs that do not belong to the bandwidth unit in the BWP can be used as interval bandwidth resources. Table 1 shows an example of BWP Information Element (IE, Information Element); as shown in Table 1, subband indicates a bandwidth unit, and locationAndBandwidth indicates the starting resource block and the number of resource blocks of the BWP.
[0085]
Table 1
[0086]

[0087]
In an embodiment, the resource blocks included in one or more bandwidth units are used as BWP resource blocks, and the resource blocks outside the bandwidth units are used as interval bandwidth resources.
[0088]
For example, the common RB included in the BWP is configured in the configuration information of the BWP, and at least one bandwidth unit is configured, and the common RB included in the at least one bandwidth unit in the configuration information is the RB included in the BWP. The common RB between two bandwidth units can be used as an interval bandwidth resource. Table 2 shows another example of BWP IE; as shown in Table 2, subband represents a bandwidth unit.
[0089]
Table 2
[0090]

[0091]
In an embodiment, the configuration information of the BWP further includes the configuration information of the interval bandwidth resource as an optional configuration, and the configured at least one bandwidth unit and/or the configured interval bandwidth resource is used as the BWP resource.
[0092]
For example, in the configuration information of the BWP, the common RB included in the BWP is configured. In the configuration information of the BWP, in addition to at least one bandwidth unit, the interval bandwidth resource is also selected to be configured, then at least one bandwidth unit and the common RB included in the interval bandwidth That is, the RB included in the BWP; if at least one bandwidth unit is configured in the configuration information of the BWP and no interval bandwidth resource is selected, then the common RB of at least one bandwidth unit is the RB included in the BWP. Table 3 shows another example of BWP IE; as shown in Table 3, subband represents bandwidth unit, and guardband represents interval bandwidth.
[0093]
table 3
[0094]

[0095]
In an embodiment, the bandwidth unit is configured with information indicating the starting resource block and the number of resource blocks; or, the bandwidth unit is configured with starting resource block information. At least two bandwidth units configured in a partial bandwidth (BWP) can include at least one same resource block, or any two bandwidth units configured in a partial bandwidth (BWP) do not include the same resource block.
[0096]
For example, the starting common RB and the number of common RBs included can be configured, or one bandwidth unit includes at least one channel idle detection bandwidth unit, and the number of RBs included in one channel idle detection bandwidth unit is a predefined value. The starting common RB and the number of channel idle detection bandwidth units included in the bandwidth unit (that is, the number of predefined values) can be configured. Table 4 shows an example of the subband IE; as shown in Table 4, subband indicates a bandwidth unit, and locationAndBandwidth indicates the starting resource block and the number of resource blocks of the subband.
[0097]
Table 4
[0098]

[0099]
Fig. 6 is an example diagram of the BWP and bandwidth unit of the embodiment of the present invention. As shown in Fig. 6, the size of the two bandwidth units configured in the BWP can be the same or different; in addition, the two bandwidth units can contain the same Public RB.
[0100]
FIG. 7 is another example diagram of the BWP and bandwidth unit according to the embodiment of the present invention. As shown in FIG. 7, the size of the two bandwidth units configured in the BWP can be the same or different; in addition, any two of the bandwidth units configured in the BWP The bandwidth unit does not contain the same common RB.
[0101]
For another example, the bandwidth unit is the channel idle detection bandwidth unit, the number of RBs contained in a channel idle detection bandwidth unit is a predefined value, the configuration information of the bandwidth unit includes the starting RB of the bandwidth unit, and then according to the predefined RB number The number can determine the frequency domain position of the bandwidth unit. Table 5 shows another example of subband IE; as shown in Table 5, subband represents a bandwidth unit, and StartingRB indicates the starting resource block of the subband.
[0102]
table 5
[0103]

[0104]
FIG. 8 is another example diagram of a BWP and a bandwidth unit according to an embodiment of the present invention. As shown in FIG. 8, any two bandwidth units configured in the BWP do not include the same common RB and have the same size.
[0105]
The resource allocation is schematically described above, and the resource scheduling unit is described below.
[0106]
In an embodiment, a plurality of resource units with a frequency domain interval of a predetermined value in a partial bandwidth (BWP) are divided into one resource scheduling unit.
[0107]
Take the above row resource scheduling unit Interlace as an example. For example, a subcarrier cluster with a predefined value in the frequency domain in a part of the bandwidth belongs to an uplink resource scheduling unit (interlace); where the predefined value is the number of RBs or the number of subcarriers. number. The sub-carrier cluster can be a resource block or a resource unit composed of an integer number of sub-carriers. The number of subcarriers included in the subcarrier cluster is a predefined value.
[0108]
FIG. 9 is an example diagram of Interlace division according to an embodiment of the present invention. As shown in FIG. 9, for example, the sub-carrier cluster is RB, and the predefined frequency domain interval value is 9. Part of the bandwidth contains 106 RBs with index values ​​of 0, 1, ..., 105, so RBs with a frequency domain interval of 9 belong to the same uplink resource scheduling unit. Then there are 10 uplink resource scheduling units in the partial bandwidth.
[0109]
As shown in FIG. 9, for example, the uplink resource scheduling unit 0 includes RB0, RB10, RB20, ..., RB100. The uplink resource scheduling unit 1 includes RB1, RB11, RB21, ..., RB101.
[0110]
In another embodiment, at least one bandwidth unit in the partial bandwidth (BWP) is divided into resource scheduling units, and multiple resource units with a predetermined frequency domain interval in one bandwidth unit are divided into one resource scheduling unit.
[0111]
Take the above row resource scheduling unit Interlace as an example. For example, the bandwidth units in a part of the bandwidth are divided into uplink resource scheduling units, and the subcarrier clusters in the bandwidth units whose frequency domain interval is a predefined value belong to one uplink resource scheduling unit.
[0112]
FIG. 10 is another example diagram of Interlace division according to an embodiment of the present invention. As shown in Figure 10, for example, a partial bandwidth contains 106 RBs, where the frequency domain resources from RB0 to RB50 are configured as bandwidth unit 1, the frequency domain resources from RB55 to RB105 are configured as bandwidth unit 2, and the frequency domain resources from RB51 to RB54 are configured as bandwidth unit 2. Frequency domain resources are interval bandwidth resources.
[0113]
As shown in Figure 10, the subcarrier cluster is RB, the predefined frequency interval value is 9, the uplink resource scheduling unit 0 in bandwidth unit 1 includes RB0, RB10,..., RB50, and the uplink resource scheduling unit 0 in bandwidth unit 2 includes RB55, RB65,..., RB105; the uplink resource scheduling unit 1 in bandwidth unit 1 includes RB1, RB11,..., RB41, and the uplink resource scheduling unit 1 in bandwidth unit 2 includes RB56, RB66,..., RB96.
[0114]
In addition, when the network device supports scheduling interval bandwidth resources, the network device may configure the terminal device with the uplink resource scheduling unit to which the resources in the interval bandwidth resource belong. When the network device indicates that the interval bandwidth resource is a schedulable resource, the terminal device considers that the interval bandwidth resource belonging to the uplink resource scheduling unit scheduled by the network device is scheduled.
[0115]
For example, the interval bandwidth resource in FIG. 10 includes 4 RBs. The network equipment respectively configures the 4 RBs in the interval bandwidth resource, which belong to the uplink resource scheduling unit 1, 2, 3, 4 in the order of the index value from small to large; that is, RB51 belongs to uplink resource scheduling unit 1, and RB52 belongs to uplink resource scheduling Unit 2, RB53 belongs to the uplink resource scheduling unit 3, and RB54 belongs to the uplink resource scheduling unit 4.
[0116]
When the network device indicates that the interval bandwidth resource between bandwidth unit 1 and bandwidth unit 2 is a schedulable resource, if the network device schedules uplink resource scheduling unit 3, then the terminal device considers that RB53 in the interval bandwidth resource is also scheduled at the same time, and The size of the transmission block can be determined by the size of the scheduled resource.
[0117]
When the network device sends the indication information for scheduling the terminal device to send uplink data to the terminal device, the terminal device can detect the channel idle state where the scheduled resource is located before sending the uplink data. When the channel idle detection bandwidth unit of the scheduled resource is in an idle state, the terminal device sends uplink data on the scheduled resource; otherwise, it does not send data on the scheduled resource.
[0118]
FIG. 11 is a schematic diagram of detecting bandwidth units according to an embodiment of the present invention. As shown in FIG. 11, for example, if the channel idle detection bandwidth units in the bandwidth unit are all in an idle state, the terminal device sends data on the scheduled resource ; If there is at least one channel idle in the bandwidth unit, detecting that the bandwidth unit is not in an idle state (that is, a busy state), the terminal device does not send data on the scheduled resource.
[0119]
The resource scheduling method is described below.
[0120]
In an embodiment, a configured bandwidth unit can be activated by a network device through a media access control (MAC, Media Access Control) control element (CE, Control Element) or downlink control information (DCI, Downlink Control Information), which is activated A configured bandwidth unit is the scheduling bandwidth resource.
[0121]
For example, in one scheduling, the base station only schedules resources of one configured bandwidth unit for uplink data transmission. The base station activates one of the configured bandwidth units through MAC CE signaling, and the base station can only schedule the resources in the activated bandwidth unit to transmit data.
[0122]
For another example, the base station may indicate the scheduled bandwidth unit through an indication field in the DCI, and the number of bits included in the indication field is determined by the number of bandwidth units configured in the BWP. For example, if 4 bandwidth units are configured in the BWP, the indication field in the DCI contains 2 bits, '00' indicates a bandwidth unit with an index value of 0, and '01' indicates a bandwidth unit with an index value of 1.
[0123]
Or, the number of bits contained in the indication field in the DCI is a predefined value, for example, if the predefined value is 3, then the maximum number of bandwidth units configured in the BWP is 8, and the value of the indication field is the same as the configured bandwidth The index values ​​of the units can be one-to-one in ascending order, that is, '000' indicates a bandwidth unit with an index value of 0, '001' indicates a bandwidth unit with an index value of 1, and so on.
[0124]
In another embodiment, at least one configured bandwidth unit may be activated by a network device through MAC CE or downlink control information (DCI), and the activated at least one bandwidth unit is a scheduled bandwidth resource.
[0125]
For example, in one scheduling, the base station schedules the resources of at least one bandwidth unit to transmit data, and the frequency domain resources of any two scheduled bandwidth units do not overlap. The base station activates at least one bandwidth unit through MAC CE signaling, and the base station schedules data transmission resources in the activated at least one bandwidth unit.
[0126]
For another example, the base station indicates the scheduled bandwidth unit through an indication field in the DCI. The indication field can indicate a resource indication value (RIV, Resource Indication Value), that is, through a triangular binary tree coding method, the resource indication value determines the starting position and the number of resources. The UE determines the multiple consecutive bandwidth units to be scheduled according to the value of the indication field. The indication field can also be a bitmap. Each bit in the bitmap corresponds to the configured bandwidth unit one-to-one. The length of the bitmap can be a predefined value, or the number of bits in the bitmap can be the same as part of the bandwidth. The number of bandwidth units configured in is equal.
[0127]
In an embodiment, the resource scheduling information indicates at least one resource scheduling unit scheduled by the network device; wherein, the resource belonging to the scheduled bandwidth resource in the scheduled at least one resource scheduling unit is used to determine the size of the transmission block; or, it is scheduled The resource in which at least one resource scheduling unit overlaps the scheduling bandwidth resource is used to determine the size of the transmission block.
[0128]
For example, the UE considers the interval bandwidth resource between two adjacent bandwidth units scheduled by the base station as a schedulable resource. If the interval bandwidth resource contains resources belonging to the uplink resource scheduling unit scheduled by the base station, the UE considers the interval bandwidth resource Resources belonging to the uplink resource scheduling unit scheduled by the base station are scheduled. If an interval bandwidth resource is not between two adjacent scheduled bandwidth units, that is, when the resource adjacent to the interval bandwidth resource includes a bandwidth unit that is not scheduled by the base station, the resource scheduled by the base station does not include the interval bandwidth resource. Resource, the UE considers that the resource in the bandwidth resource of the interval is not scheduled.
[0129]
Fig. 12 is a schematic diagram of a bandwidth unit according to an embodiment of the present invention. As shown in Fig. 12, for example, the base station schedules bandwidth unit 1 in part of the bandwidth and uplink resource scheduling units 0 and 1 in bandwidth unit 2. Since bandwidth unit 1 and bandwidth unit 2 are continuous bandwidth units, the UE considers interval bandwidth resources as schedulable resources, and resources belonging to uplink resource scheduling units 0 and 1 (for example, RB51) are also scheduled for sending uplink data. And if the bandwidth unit 3 is not scheduled by the base station, the resources belonging to the uplink resource scheduling units 0 and 1 in the interval bandwidth resources between the bandwidth units 2 and 3 are not scheduled by the base station. In this way, the UE can determine the size of the scheduled resource, thereby calculating the transport block size.
[0130]
In an embodiment, the indication information may indicate the scheduled bandwidth resource, and the terminal device determines whether the interval bandwidth resource belongs to the scheduled bandwidth resource according to the scheduled bandwidth resource.
[0131]
For example, if the system does not support flexibly adjusting the scheduling bandwidth resource, the UE can determine whether the interval bandwidth is scheduled according to the bandwidth unit contained in the scheduled bandwidth resource. If the scheduled bandwidth resource includes two adjacent bandwidth units, the UE considers the corresponding bandwidth unit. The interval bandwidth between two adjacent bandwidth units belongs to the scheduled bandwidth resource, and the resource that overlaps the scheduled bandwidth resource in the scheduled uplink resource scheduling unit is used to determine the size of the transmission block. When the adjacent bandwidth units on both sides of an interval bandwidth are not scheduled at the same time, the UE considers that the interval bandwidth is not scheduled.
[0132]
For another example, the system does not support flexible adjustment of scheduling bandwidth resources, and the base station activates at least one bandwidth unit and/or interval bandwidth configured as a scheduling bandwidth resource through MAC CE or downlink control information. Then the scheduled uplink resource scheduling unit is the same as the scheduled bandwidth resource. Overlapping resources are used to determine the size of the transmission block. That is to say, if the interval bandwidth is activated by MAC CE or downlink control information, it is used as a scheduling bandwidth resource, and if it is not activated, it is not used as a scheduling bandwidth resource.
[0133]
In an embodiment, the indication information indicates whether the network device and/or the terminal device uses the channel idle detection result to adjust the size of the scheduled bandwidth resource.
[0134]
In an embodiment, the indication information can be sent through at least one of the following: Radio Resource Control (RRC, Radio Resource Control) signaling, medium access control (MAC) control element (CE), downlink control information (DCI); The invention is not limited to this.
[0135]
For example, the base station and/or the UE can adopt scheduling bandwidth adaptation (that is, the scheduling bandwidth resource can be adjusted in size according to the result of channel idle detection). The UE may determine whether one or more resources in the interval bandwidth resource are scheduled according to the indication information of the base station.
[0136]
In one embodiment, in the case where the indication information indicates that the network device and/or the terminal device does not use the channel idle detection result to adjust the size of the scheduled bandwidth resource, the terminal device determines between two adjacent bandwidth units scheduled by the network device The interval bandwidth resource belongs to the scheduling bandwidth resource.
[0137]
In one embodiment, when the indication information indicates that the network device and/or the terminal device adopts the channel idle detection result to adjust the size of the scheduled bandwidth resource, the terminal device determines that the interval bandwidth resource between two adjacent bandwidth units is not affected. The network equipment scheduling.
[0138]
For example, if the base station does not support scheduling bandwidth adaptive transmission or reception, the UE determines whether the interval bandwidth resource is a schedulable resource through the bandwidth unit scheduled by the base station; the interval bandwidth resource between two adjacent bandwidth units scheduled by the base station is a schedulable resource. Scheduling resources, otherwise, the interval bandwidth resources are not scheduled by the base station.
[0139]
For another example, the base station indicates whether the UE adopts scheduling bandwidth adaptive transmission and/or reception. If the UE adopts scheduling bandwidth adaptation, the interval bandwidth resource is not scheduled by the base station; if the UE does not adopt scheduling bandwidth adaptation, the interval bandwidth resource between two adjacent bandwidth units scheduled by the base station is a schedulable resource; otherwise, the interval bandwidth resource is a schedulable resource. Bandwidth resources are not scheduled by the base station.
[0140]
The above description is given as an example of the upper resource scheduling unit Interlace, and the following description is given as an example of the lower resource scheduling unit RBG.
[0141]
FIG. 13 is another example diagram of a BWP according to an embodiment of the present invention. As shown in FIG. 13, the number of RBGs included in a partial bandwidth (BWP) can be used to calculate the number of RBGs in a downlink resource scheduling unit.
[0142]
FIG. 14 is another example diagram of a BWP according to an embodiment of the present invention. As shown in FIG. 14, the number of RBGs included in a bandwidth unit can be calculated separately, and the interval bandwidth resource is used as one RBG.
[0143]
For example, the UE may determine whether the resource in the interval bandwidth is scheduled according to the indication information of the base station. If the base station does not support scheduling bandwidth adaptive downlink data transmission, the UE can determine whether the interval bandwidth is a schedulable resource through the bandwidth unit scheduled by the base station.
[0144]
For example, if the indication field of the downlink resource scheduling unit indicates that the downlink resource scheduling unit in two adjacent bandwidth units is scheduled, and the downlink resource scheduling unit that is not shared with the interval bandwidth is scheduled, then the UE considers the interval bandwidth to be available. Scheduling bandwidth.
[0145]
Taking Figure 13 as an example, the UE receives the downlink resource scheduling unit sent by the base station, and the indication field indicates that RBG0, RBG1, RBG13, and RBG15 are scheduled. This includes RBG0, RBG1 and bandwidth units that are not shared with the interval bandwidth in bandwidth unit 1. If the RBG 15 in 2 is not shared with the interval bandwidth, the UE considers the interval bandwidth between bandwidth units 1 and 2 as a schedulable resource, and all RBs in the RBG 13 scheduled by the base station are scheduled.
[0146]
For another example, if a downlink resource scheduling unit that is not shared with the interval bandwidth in one of the two adjacent bandwidth units is not scheduled, the UE considers the interval bandwidth between the two adjacent bandwidth units as unschedulable resources.
[0147]
Still taking Figure 13 as an example, the UE receives the downlink resource scheduling unit sent by the base station, and the indication field indicates that RBG 0 to 13 are scheduled. This includes RBG 0 to RBG 12 that are not shared with the interval bandwidth in bandwidth unit 1, but does not include bandwidth. If the RBG in unit 2 is not shared with the interval bandwidth, the UE considers the interval bandwidth between bandwidth units 1 and 2 as unschedulable resources. Therefore, RB51 to RB54 belonging to the interval bandwidth in RBG13 are not scheduled by the base station and only belong to bandwidth unit 1. RB is scheduled.
[0148]
For another example, the indication field of the downlink resource scheduling unit may indicate the scheduled downlink resource scheduling unit through a bitmap. If the indication field of the downlink resource scheduling unit indicates that the interval bandwidth between two adjacent bandwidth units is scheduled, the UE considers the interval bandwidth as an available resource. If the indication field of the downlink resource scheduling unit indicates that the interval bandwidth between two adjacent bandwidth units is not scheduled, the UE considers the interval bandwidth as an unschedulable resource.
[0149]
For another example, the indicator field of the downlink resource scheduling unit may indicate the downlink resource scheduling unit by indicating the resource indicator value (the resource indicator value indicates the starting downlink resource scheduling unit for scheduling and the number thereof). If the indication field of the downlink resource scheduling unit indicates that the downlink resource scheduling unit in two adjacent bandwidth units is scheduled by the base station, the UE considers the interval bandwidth as an available resource. If the downlink resource scheduling unit indicated for scheduling in the indication field of the downlink resource scheduling unit only includes the downlink resource scheduling unit in one of the two adjacent bandwidth units, the UE considers the interval bandwidth as an unschedulable resource.
[0150]
For example, the base station can indicate whether to adopt scheduling bandwidth adaptation through RRC or MAC CE. If the indication adopts scheduling bandwidth adaptation, the indication range of the downlink resource scheduling unit indication field does not include the interval bandwidth resource. If the bitmap indication method is used, the number of bits contained in the bitmap can be equal to the sum of the number of RBGs contained in each bandwidth unit in the BWP; if the resource indicator value method is used, the number of consecutive RBGs indicated by the resource indicator value does not include Interval bandwidth resources.
[0151]
FIG. 15 is another example diagram of BWP according to the embodiment of the present invention. As shown in FIG. 15, for example, if the base station schedules 4 RBGs starting from RBG12, the scheduled RBGs are RBG12, RBG13, RBG14, RBG15, which does not include the interval Bandwidth includes RB51 to RB54.
[0152]
For another example, the base station may indicate whether to adopt scheduling bandwidth adaptation through DCI. The total number/range of resource block groups indicated by the indication field of the downlink resource scheduling unit is the total number of resource block groups divided above (that is, the total number of RBGs including the interval bandwidth resource is calculated). If the DCI indicates to adopt scheduling bandwidth adaptation, the UE considers that the resources in the interval bandwidth are not scheduled by the base station.
[0153]
If RRC signaling or MAC CE or DCI indicates that scheduling bandwidth adaptation is not used, it is the same as the method in which the aforementioned base station does not support scheduling bandwidth adaptation.
[0154]
