Detailed Description
In order to make the objects, 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, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the present invention.
It should be noted that, in this document, relational terms such as "first" and "second", and the like are used only to distinguish the same names, and do not imply a relationship or order between the names.
As shown in fig. 1, the present embodiment discloses a resource allocation method, where an execution subject of the present embodiment is a base station, and the method may include the following steps 101 and 102:
101. and allocating resources for User Equipment (UE) to generate resource configuration information.
102. Sending the resource configuration information to the UE, wherein the resource configuration information comprises a first part of information and a second part of information; wherein the first part of information is used for indicating information of a target basic bandwidth allocated to the UE, and the second part of information is used for indicating a target resource block group used by the UE in the target basic bandwidth; the target basic bandwidth is at least one of a plurality of preset basic bandwidths (that is, the first part of information may indicate that 1 basic bandwidth is the target basic bandwidth or indicate that a plurality of basic bandwidths are the target basic bandwidths), and the target resource block group is at least one of a plurality of resource block groups included in the target basic bandwidth (that is, the second part of information indicates at least one resource block group in the target basic bandwidth, and if the target basic bandwidth is the plurality of basic bandwidths, the second part of 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, a large bandwidth of a 5G communication system is divided into a plurality of basic bandwidths, each basic bandwidth includes the same number of RBs, for example, for a UE using a 400M bandwidth, (assuming that the 400M bandwidth is composed of 6600 subcarriers, the subcarrier spacing is 60k, and the total number of RBs is 550), this embodiment divides the 400M bandwidth into 5 basic bandwidths, each basic bandwidth includes 110 RBs, and the 110 RBs may include 1 or more RBs of numerical information (numerology). For the RBs containing 1 piece of numerical information, namely dividing the RBs by adopting the same subcarrier interval, wherein the frequency width of each RB is the same; for the RB containing multiple pieces of numerical information, that is, the RB is divided by using different subcarrier intervals, the frequency widths of the RBs are different. It can be seen that, in the present 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, to reduce signaling overhead, a resource block group RBG is determined by using the number of RBs as a discussion unit, where each RBG includes at least one RB, for example, each RBG includes 4 RBs. The base station allocates resources for the UE, and the generated resource configuration information comprises two parts of information: a first part of information and a second part of information; the first part of information is used for indicating information of a target basic bandwidth allocated to the UE, namely the UE can determine the information allocated to the basic bandwidth based on the first part of information; the second part of information is used to indicate a target resource block group used by the UE in the target basic bandwidth, that is, the second part of information is used to indicate a specific resource allocation in the "basic bandwidth" of the UE.
It can be seen that, in the resource allocation method provided in the embodiment of the present invention, the number of RBs is used as a discussion unit to determine resource block groups RBGs, each RBG includes at least one RB, and then resource allocation is performed on the RBGs, a smaller control information load is used, flexible resource scheduling is provided for the UE, signaling overhead is reduced, and the method is applicable to a large bandwidth scenario of a 5G communication system and is compatible with an existing resource allocation manner.
In a specific example, the information of the target basic bandwidth in step 102 includes a number and a sequence number of the target basic bandwidth, and the first part of information in step 102 includes a first bitmap, where the first bitmap is used to indicate the number and the sequence number of the target basic bandwidth.
In this embodiment, the second part of information in step 102 includes a second bitmap, and the second bitmap is used to indicate the target resource block group.
In this embodiment, for example, a 400M bandwidth is divided into 5 basic bandwidths, which are named basic bandwidth 1, basic bandwidth 2, …, and basic bandwidth 5 in sequence. Each basic bandwidth comprises 110 RBs, each RBG comprises 4 RBs, and the first part of information includes a first bitmap, where the first bitmap is used to indicate the number and sequence number of the target basic bandwidth, and the first bitmap is composed of 5 bits, for example, the first bitmap is 10000, which indicates that a basic bandwidth is allocated to the UE, and the basic bandwidth is a basic bandwidth 1; the first bitmap is 10100, which indicates that two basic bandwidths, specifically, basic bandwidth 1 and basic bandwidth 3, are allocated to the UE.
In this embodiment, for example, if one RBG is composed of 4 RBs, each basic bandwidth includes 110 RBs, the second part of information includes a second bitmap, where the second bitmap is used to indicate the target resource block group, and the second bitmap is composed of 28 bits to indicate which RBGs are used by the UE, and a specific indication manner is similar to the first bitmap, which is not described again in this embodiment.
In a specific example, if the number of the target basic bandwidths is multiple, the second part of information includes one second bitmap to indicate the target resource block groups included in each target basic bandwidth, or the second part of information includes multiple second bitmaps to respectively indicate the target resource block groups included in each target basic bandwidth.
In a specific example, the information of the target basic bandwidth in step 102 includes a starting position of the target basic bandwidth, and the resource configuration information in fig. 1 further includes a third part of information; correspondingly, the first part of information is an indication identifier for indicating a starting position of a target basic bandwidth allocated to the UE, and the third part of information is for indicating the number of resource blocks included in the resource block group, so that the UE determines the number of the target basic bandwidth based on the third part of information.
In this embodiment, the second part of information in step 102 includes a second bitmap, and the second bitmap is used to indicate the target resource block group.
In this embodiment, for example, a 400M bandwidth is divided into 5 basic bandwidths, each basic bandwidth includes 110 RBs, each basic bandwidth corresponds to a start position, the first part of information is an indication identifier for indicating the start position of a target basic bandwidth allocated to the UE, and the first part of information is composed of 3 bits, that is, any one of the 5 start positions can be indicated; the second part of information comprises a second bitmap, the second bitmap is used for indicating the target resource block group, and the second bitmap is composed of 28 bits and indicates which RBGs are used by the UE; the third part 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 determines the number of the target basic bandwidth based on the third part information, and the UE is preconfigured with a corresponding relationship between the RBG size and the number of the basic bandwidth. In this embodiment, there are 5 types of RBGs, each corresponding to the number of target basic bandwidths, as shown in table one, the third part of information is composed of 3 bits, that is, any one of the 5 RBGs can be indicated, so that the UE determines the number of target basic bandwidths based on the third part of information.

As shown in table one, the third part of information is used to indicate the number of resource blocks included in the resource block group, i.e., the RBG size, which is the granularity of resource allocation, so that the UE determines the number of the target basic bandwidth based on the RBG size, and if the RBG size is 8, the scheduled basic granularity of the UE is 8 RBs, and at the same time, the number of the target basic bandwidth may be determined to be 2.
In a specific example, the second part of information of step 102 includes an offset indication and a resource mapping indication, the offset indication is used to indicate that the target resource block group is located in the region range of the target basic bandwidth, 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 region range of the target basic bandwidth, as shown in table two.
Watch two
State 1 First 14 RBGs
State 2 Last 14 RBGs
State 3 Using all RBGs
State 4 Reservation
For example, if one RBG is composed of 4 RBs and each basic bandwidth includes 110 RBs, then each basic bandwidth has 28 RBGs, and in table two, if the offset indicates 00, a state 1 is indicated to indicate that the target resource block group is located in the first half region range of the target basic bandwidth, which may also be understood as that the target resource block group is located in the first 14 RBGs of the 28 RBGs; if the offset indication is 01, a status 228 is indicated for indicating that the target resource block group is located in the second half region range of the target basic bandwidth, which may also be understood as that the target resource block group is located in the last 14 RBGs of the 28 RBGs; if the offset indication is 10, state 3 is indicated for indicating that the target resource block group is located in the whole region of the target basic bandwidth, which can also be understood as that the target resource block group includes all 28 RBGs.
In this embodiment, the resource mapping indication is represented by a third bitmap, where the third bitmap is used to indicate the target resource block group, the resource mapping indication is composed of 14 bits, and when the offset indication indicates a state 3, the resource mapping indication field is reserved.
Compared with the method that 28 bits are adopted to form the second part of information, in the embodiment, the second part of information only needs 2 bits to form the offset indication and 14 bits to form the resource mapping indication, so that the signaling overhead is further reduced.
In a specific example, the method shown in fig. 1 further comprises the following steps not shown in fig. 1:
selecting a corresponding Downlink Control Information (DCI) format according to the size of the bandwidth resource allocated to the UE;
and sending DCI information to the UE according to the DCI format, wherein the DCI information carries the resource configuration information.
In this embodiment, different Downlink Control Information (DCI) sizes are designed for different bandwidth resources, and the different DCI sizes correspond to different DCI formats. For example, DCI format 1 is designed for resources within a bandwidth of 20MHz, DCI format 2 is designed for resources within a bandwidth of 100MHz, and DCI format 3 is designed for resources within a bandwidth of 400 MHz.
In this embodiment, after acquiring the DCI message, the UE performs blind decoding on the DCI message using different DCI formats, and determines the bandwidth size allocated to the UE through the DCI format corresponding to the blind decoding success.
In a specific example, for the table-related embodiment, the UE is notified of the number of resource blocks included in the resource block group by 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, adopts the explicit indication in four ways:
mode 1: the resource block group size is indicated by System Information (SI).
Mode 2: the Resource block group size is indicated by a Radio Resource Control (RRC) message.
Mode 3: the resource block Group size is indicated by a Group Common downlink control channel (Group Common PDCCH).
Mode 4: the Resource block group size is indicated by a 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, adopts the implicit indication including two ways:
the first method is as follows: different resource block group sizes are implicitly indicated by different sets of the control resource set, for example, the control resource set 1 indicates that the resource block group size is 4, the control resource set 2 indicates that the resource block group size is 8, and the like.
The second method comprises the following steps: the resource block group size is implicitly indicated by using Demodulation Reference Signal (DMRS) sequence information of a control channel, for example, each UE blindly detects multiple sequences when detecting a DMRS sequence, and different sequences implicitly indicate different resource block group sizes.
As can be seen, 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, and when the resource bandwidth occupied by the UE changes, the size of the RBG and the size of the RA domain of the DCI do not change, and in fig. 1, the size of the RA domain is 5bit +28 bit.
