Description

Frequency domain resource indicating and determining method, network equipment and terminal
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for indicating and determining frequency domain resources, a network device, and a terminal.
Background
The Resource Allocation Type 1(Resource Allocation Type 1) in the NR indicates an allocated RB set by jointly encoding a starting RB (Resource block) and the number of RBs, and the size of a frequency domain Resource indication field in DCI (Downlink control information) is proportional to the size of a BWP (BandWidth Part) (i.e., the number of RBs included in the BWP).
When DCI size of DCI format 0_0 and DCI format 1_0 in USS (UE-specific Search Space) is based on the size of DCI format 1_0
Figure BDA0001808520810000011
(initial BWP or number of RBs contained by CORESET0(COntrol REsourceSET, COntrol resource set 0)), but is to be used to indicate a size of
Figure BDA0001808520810000012
When allocating frequency domain resources in the active BWP (the number of RBs included in the active BWP), the initial number of RBs and the initial number of RBs are each multiplied by K. I.e. the starting RB that the DCI can indicate is

RB number of

Wherein, if
Figure BDA0001808520810000016
Then K is satisfied
Figure BDA0001808520810000017
Maximum value in the set {1,2,4,8 }; otherwise K is 1.
The mechanism is essentially divided in units of K RBs starting from RB0 in activating BWP

One RB Unit, frequency-domain resource allocation in DCI to Start RB Unit RB'startAnd RB Unit number L'RBsAnd (4) joint coding. Wherein, L'RBs＝LRBs/K,RB′start＝RBstart/K。
The RB (RB bundle) in the NR (Resource Block Group), PRG (Physical Resource Group), and VRB (Virtual Resource Block) to PRB mapping are divided based on the CRB (Common Resource Block) number. Depending on the starting position of BWP and the BWP size, the number of RBs contained in the first and/or last cell may be small.
Assuming a unit granularity P of RBG (Resource Block Group), PRG (Pre-coded Resource Block Group) and RBbundle, the starting point of BWP is

BWP of size
Figure BDA0001808520810000022
The first RBG, PRG and RBbundle unit contains RB number
Figure BDA0001808520810000023
The number of RBs contained in the last unit of RBG, PRG and RB bundle is as follows:
if it is
Figure BDA0001808520810000024
The last cell contains the number of RBs as
Figure BDA0001808520810000025
Otherwise, the number of RBs contained in the last unit is P.
In the conventional mechanism, the DCI size of the DCI format 0_0/1_0 in the USS is determined according to
Figure BDA0001808520810000026
It is determined that when the frequency-domain resource allocation in BWP is activated, RB units of the frequency-domain resource allocation are always divided in units of K RBs starting from the first RB in BWP, i.e., the starting RB of the frequency-domain resource allocation is always an integer multiple of K. Assuming that K is 2 and the unit size of RBG, PRG, and RBbundle is also 2, the start point of BWP is set to be 2
Figure BDA0001808520810000027
Odd and BWP is even, the RBG, PRG and RB bundle are divided as shown in fig. 1, the first and last cells each include only one RB, and the other cells include two RBs. Also as shown in FIG. 1, the starting RB of the frequency domain resource allocation is the 0 th, 2 nd, … th even RB within BWP. It can be seen that the unit of frequency domain resource allocation is inconsistent with the partition of the RBG, PRG, and RB bundle, which may lead to the problems of resource waste, scheduling complexity increase, channel estimation performance decrease, and/or reception complexity increase.
Specifically, for example, the PDSCH frequency domain resources allocated by the network side for the UE are RB units 1 and 2, that is, correspond to VRB2-5, and since VRB2 in RBG1 is occupied, RBG1 cannot be allocated in a resource allocation manner based on RBG, and furthermore, neither VRB2 nor VRB5 can adopt joint channel estimation, which may deteriorate channel estimation performance and increase reception complexity of the UE.
