Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are disclosed.

It should be noted that, in this document, relational terms such as "first" and "second" are only used to distinguish the same names, rather than implying the relationship or order between these names.

As shown in FIG. 1 , this embodiment discloses a resource allocation method. The execution subject of this embodiment is a base station, and the method may include the following steps 101 and 102:

101. Allocate resources to user equipment (User Equipment, UE), and generate resource configuration information.

102. Send the resource configuration information to the UE, where the resource configuration information includes a first part of information and a second part of information; wherein the first part of information is used to indicate the information of the target basic bandwidth allocated to the UE, The second part of the information is used to indicate the target resource block group used by the UE in the target basic bandwidth; the target basic bandwidth is at least one of multiple preset basic bandwidths (that is, the first part of the information may indicate 1 basic bandwidth is the target basic bandwidth or multiple basic bandwidths are indicated as the target basic bandwidth), and the target resource block group is at least one of the multiple resource block groups included in the target basic bandwidth (that is, the second part of the information Indicates at least one resource block group in the target basic bandwidth, if the target basic bandwidth is multiple basic bandwidths, the second part of the information may indicate at least one resource block group in each basic bandwidth).

In this embodiment, the number of resource blocks included in each basic bandwidth is the same.

In this embodiment, the large bandwidth of the 5G communication system is divided into multiple basic bandwidths, and each basic bandwidth includes the same number of RBs. For example, for a UE using a 400M bandwidth, (assuming that the 400M bandwidth consists of 6600 subcarriers, the subcarrier spacing is 60k) , including a total of 550 RBs), this embodiment divides the 400M bandwidth into 5 basic bandwidths, each basic bandwidth includes 110 RBs, and the 110 RBs may include one or more RBs of numerical information (numerology). For RBs containing 1 numerical information, that is, the same subcarrier spacing is used to divide RBs, and the bandwidth of each RB is the same; for RBs containing multiple numerical information, that is, different subcarrier spacings are used to divide RBs, The bandwidth of the RB is different. It can be seen that, in this embodiment, the basic bandwidth is divided based on the number of RBs, and each basic bandwidth includes the same number of RBs, but the RB bandwidths may be different.

In this embodiment, in order to reduce signaling overhead, the number of RBs is used as a discussion unit to determine a resource block group RBG, each RBG includes at least one RB, for example, each RBG includes 4 RBs. The base station allocates resources to the UE, and the generated resource configuration information includes two parts of information: a first part of information and a second part of information; where the first part of information is used to indicate the information of the target basic bandwidth allocated to the UE, that is, the UE is based on the first part of information. A part of the information can determine the information allocated to the basic bandwidth; the second part of the information is used to indicate the target resource block group used by the UE in the target basic bandwidth, that is, the second part of the information is used to indicate the specific “basic bandwidth” of the UE. resource allocation.

It can be seen that, in the resource allocation method proposed by the embodiment of the present invention, the number of RBs is used as the discussion unit to determine the resource block group RBG, each RBG contains at least one RB, and then resource allocation is performed for the RBG, using a smaller control information load, as The UE provides flexible resource scheduling, reduces signaling overhead, is suitable for large-bandwidth scenarios in 5G communication systems, and is compatible with existing resource allocation methods.

In a specific example, the information about the target basic bandwidth in step 102 includes the number and sequence number of the target basic bandwidth, and the first part of the information in step 102 includes a first bitmap, and the first bitmap is used to indicate the The number and sequence number of the target basic bandwidth.

In this embodiment, the second part of the information in step 102 includes a second bitmap, where the second bitmap is used to indicate the target resource block group.

In this embodiment, for example, the 400M bandwidth is divided into five basic bandwidths, which are named as basic bandwidth 1, basic bandwidth 2, . . . , and basic bandwidth 5 in sequence. Each basic bandwidth includes 110 RBs, and each RBG includes 4 RBs, the first part of the information includes a first bitmap, the first bitmap is used to indicate the number and sequence number of the target basic bandwidth, the first bit The picture consists of 5 bits. For example, if the first bitmap is 10000, it means that one basic bandwidth is allocated to the UE, and the basic bandwidth is basic bandwidth 1; the first bitmap is 10100, which means that two basic bandwidths are allocated to the UE , specifically basic bandwidth 1 and basic bandwidth 3.

In this embodiment, for example, an RBG consists of 4 RBs, and each basic bandwidth includes 110 RBs, the second part of the information includes a second bitmap, and the second bitmap is used to indicate the target resource block group, The second bitmap is composed of 28 bits and indicates which RBGs the UE uses. The specific indication method is similar to the first bitmap, which is not repeated in this embodiment.

In a specific example, if the number of the target basic bandwidths is multiple, the second part of the information includes one of the second bitmaps to indicate the target resource block groups included in each target basic bandwidth, Or the second part of the information includes a plurality of the second bitmaps to respectively indicate the target resource block groups included in each target basic bandwidth.

In a specific example, the information about the target basic bandwidth in step 102 includes the starting position of the target basic bandwidth, and the resource configuration information in FIG. 1 further includes the third part of information; correspondingly, the first part of the information is an indication an identifier, used to indicate the starting position of the target basic bandwidth allocated to the UE, the third part of the information is used to indicate the number of resource blocks included in the resource block group, so that the UE can determine based on the third part of the information The amount of the target base bandwidth.

In this embodiment, the second part of the information in step 102 includes a second bitmap, where the second bitmap is used to indicate the target resource block group.

In this embodiment, for example, the 400M bandwidth is divided into 5 basic bandwidths, each basic bandwidth includes 110 RBs, and each basic bandwidth corresponds to a starting position, then the first part of the information is an indication identifier, which is used to indicate the allocation to the The starting position of the target basic bandwidth of the UE, the first part of the information is composed of 3 bits, which can indicate any one of the 5 starting positions; the second part of the information includes a second bitmap, and the second bitmap is used to indicate the The target resource block group, the second bitmap is composed of 28 bits, indicating which RBGs the UE uses; the third part of information is used to indicate the number of resource blocks included in the resource block group, that is, the RBG size, so that the UE is based on the The third part of the information determines the quantity of the target basic bandwidth, and the UE is preconfigured with a corresponding relationship between the size of the RBG and the quantity of the basic bandwidth. In this embodiment, there are 5 RBG sizes, each of which corresponds to the number of target basic bandwidths, as shown in Table 1, the third part of the information is composed of 3 bits, which can indicate any one of the 5 RBG sizes, so that the The UE determines the amount of the target basic bandwidth based on the third part of the information.

Table 1 Correspondence between RBG size and the number of basic bandwidths

RBG size Number of basic bandwidth 4 1 8 2 12 3 16 4 20 5

As shown in Table 1, the third part of the information is used to indicate the number of resource blocks included in the resource block group, that is, the RBG size, which is the granularity of resource allocation, so that the UE determines the target basic bandwidth based on the RBG size If the RBG size is 8, the basic granularity of UE scheduling is 8 RBs, and it can be determined that the number of target basic bandwidths is 2.

In a specific example, the second part of the information in step 102 includes an offset indication and a resource mapping indication, where the offset indication is used to indicate that the target resource block group is located within the range of the target basic bandwidth, and the The resource mapping indication is represented by a third bitmap, and the third bitmap is used to indicate the target resource block group.

In this embodiment, for example, the offset indication is composed of 2 bits, and is used to indicate that the target resource block group is located in the range of the target basic bandwidth, as shown in Table 2.

Table II

state 1 Top 14 RBGs state 2 Last 14 RBGs state 3 Use all RBGs state 4 reserved

For example, an RBG consists of 4 RBs, and each basic bandwidth contains 110 RBs, so each basic bandwidth has a total of 28 RBGs. In Table 2, if the offset indication is 00, it means state 1, which is used to indicate the target resource block The group is located in the first half of the target basic bandwidth, and it can also be understood that the target resource block group is located in the first 14 RBGs of the 28 RBGs; if the offset indication is 01, it indicates the state 228, which is used to indicate the target resource. The block group is located in the second half of the target basic bandwidth, and it can also be understood that the target resource block group is located in the last 14 RBGs of the 28 RBGs; if the offset indication is 10, it means state 3, which is used to indicate the target The resource block group is located in the entire area of the target basic bandwidth, and it can also be understood that the target resource block group includes all 28 RBGs.

In this embodiment, the resource mapping indication is represented by a third bitmap, and the third bitmap is used to indicate the target resource block group, and the resource mapping indication is composed of 14 bits. When the offset indication indicates state 3, the resource mapping indication Domain reservation.

Compared with using 28 bits to form the second part of information, in this embodiment, the second part of information only needs 2 bits to form an offset indication and 14 bits to form a resource mapping indication, which further reduces signaling overhead.

In a specific example, the method shown in FIG. 1 further includes the following steps not shown in FIG. 1 :

According to the size of the bandwidth resource allocated to the UE, select the corresponding downlink control information DCI format;

Send a DCI message to the UE according to the DCI format, where the DCI message carries the resource configuration information.

In this embodiment, different downlink control information (Downlink Control Information, DCI) sizes are designed for different bandwidth resources, and different DCI sizes correspond to different DCI formats. For example, DCI format 1 is designed for resources with a bandwidth of less than 20 MHz, DCI format 2 for resources with a bandwidth of 100 MHz, and DCI format 3 for resources with a bandwidth of 400 MHz.

In this embodiment, after the UE obtains the DCI message, the UE performs blind decoding on the DCI message using different DCI formats, and determines the bandwidth allocated to itself through the DCI format corresponding to the successful blind decoding.

In a specific example, for the embodiments related to Table 1, the number of resource blocks included in the resource block group is notified to the UE by means of an explicit indication or an implicit indication.

In this embodiment, the number of resource blocks included in the resource block group, that is, the size of the resource block group, is explicitly indicated in four ways:

Mode 1: The resource block group size is indicated by system information (System Information, SI).

Manner 2: The size of the resource block group is indicated by a radio resource control (Radio Resource Control, RRC) message.

Mode 3: The resource block group size is indicated by a group common downlink control channel (Group Common PDCCH).

Manner 4: The resource block group size is indicated by the resource assignment (Resource Assignment, RA) field of the DCI.

The number of resource blocks included in the resource block group, that is, the size of the resource block group, is implicitly indicated in two ways:

Manner 1: Different sets of control resource sets are used to implicitly indicate different resource block group sizes. For example, control resource set 1 indicates that the resource block group size is 4, and control resource set 2 indicates that the resource block group size is 8.

Mode 2: The demodulation reference signal (DMRS) sequence information of the control channel is used to implicitly indicate the size of the resource block group. For example, when each UE detects a DMRS sequence, it blindly detects multiple sequences, and different sequences implicitly indicate different resources. Block group size.

It can be seen that in the resource allocation method disclosed in the embodiment of the present invention, for example, as shown in FIG. 1 , the size of the RBG is determined according to the basic bandwidth. When the resource bandwidth occupied by the UE changes, the size of the RBG and the size of the RA field of the DCI remain unchanged. In FIG. 1 , the size of the RA field It is 5bit+28bit.

Further, in the resource allocation method disclosed in the embodiment of the present invention, for example, the relevant embodiments of Table 1, the RBG size is variable: according to the bandwidth occupied by the UE, the RBG size is changed, and the RA field size of the DCI is kept unchanged, and the RA field size is 3bit+28bit +3bit.

Compared with the prior art, in the resource allocation method proposed by the embodiments of the present invention, the number of RBs is used as a discussion unit to determine a resource block group RBG, each RBG contains at least one RB, and then resource allocation is performed for the RBG, using a smaller control The information payload provides flexible resource scheduling for UEs, reduces signaling overhead, is suitable for large bandwidth scenarios in 5G communication systems, and is compatible with existing resource allocation methods.

As shown in FIG. 2, this embodiment discloses a resource allocation method, the execution subject is a base station, and may include the following steps 201 and 202:

201. Allocate resources for user equipment UE, and generate resource configuration information;

202. Send the resource configuration information to the UE, where the resource configuration information includes a first part of information and a second part of information; wherein the first part of the information includes a resource allocation indication value, and the second part of the information includes a resource block The number of resource blocks included in the group (that is, the size of the resource block group), so that the UE can determine the number of consecutive resource blocks allocated to the UE according to the number of resource blocks included in the resource block group and the resource allocation indication value. The number of resource block groups and the starting resource block group.

In this embodiment, the second part of the information includes the size of the resource block group (RBG). The RBG size can be understood as the number of RBs included in the RBG. The UE is preconfigured with the size of the RBG, the number of RBGs, and the number of bits required by the resource allocation indication value. As shown in Table 3, there are 6 RBG sizes, each of which corresponds to the number of RBGs and the number of bits required for the resource allocation indication value, then the second part of the information consists of 3 bits, which can indicate the size of the 6 RBGs. Either one is used to notify the UE of the number of RBGs allocated.

Table 3 shows the correspondence between the RBG size, the number of RBGs and the number of bits required for the resource allocation indication value

As shown in Table 3, the second part of the information includes the RBG size. If the RBG size is 4, the UE may determine that the number of RBGs is 138.

The first part of the information includes a resource allocation indication value, which is used to indicate the starting position of the allocated resources and the number of consecutively allocated RBGs, specifically:

RIV=N(L _CRBs -1)+RB _START

else

RIV=N(NL _CRBs +1)+(N-1-RB _START )

Among them, N is the number of RBGs, which is given by Table 3, L _CRBs is the number of multiple consecutive resource block groups allocated to the UE, RIV is the resource allocation indicator value, and RB _START is the starting RBG. The number of bits required for the resource allocation indication value is calculated by the formula Log2(N×(N+1)/2).
