Resource allocation method and device, and resource determination method and device
View Patent ↗Disclosed in the present application are a resource allocation method and device. The resource allocation method provided in the present application includes: allocating a transmission configuration indication (TCI) state resource and determining TCI state resource allocation information; and notifying a terminal of the TCI state resource allocation information.
1. A resource allocation method, comprising:
allocating resources of a transmission configuration indication (TCI) state and determining TCI state resource allocation information; and
notifying a terminal of the TCI state resource allocation information by notifying a correspondence relationship between the TCI state and a preset resource allocation pattern;
wherein the preset resource allocation pattern comprises: at least first one RBG or RB being a group of resources, and the other RBGs or RBs being another group of resources.
2. A resource determination method, comprising:
determining resources of a transmission configuration indication (TCI) state according to TCI state resource allocation information notified by a network side; wherein the TCI state resource allocation information is notified by the network side by notifying a correspondence relationship between the TCI state and a preset resource allocation pattern, and the preset resource allocation pattern comprises: at least first one RBG or RB being a group of resources, and the other RBGs or RBs being another group of resources; and
determining a size of a precoded resource block group (PRG) according to the resources of the TCI state.
3. The method according to claim 2 , wherein the size of the PRG is determined in the following manner:
when downlink control information sent by the network side indicates that a value of the size of the PRG is taken from set 1, and the set 1 is {2, a continuously scheduled bandwidth} or {4, the continuously scheduled bandwidth}:
for any TCI state:
if resources corresponding to the any TCI state are continuous and greater than or equal to BWP/4, or, resources corresponding to the any TCI state are continuous, and a sum of sizes of resources corresponding to a plurality of TCI states exceeds BWP/2, the size of the PRG is a size of the resources corresponding to the any TCI state, wherein BWP is a preset part of a bandwidth;
otherwise, the size of the PRG is a value other than “the continuously scheduled bandwidth” in the set 1.
4. The method according to claim 2 , wherein a precoding manner in resources with the size of the PRG is kept unchanged.
5. A resource allocation apparatus, comprising:
a memory, configured to store a program instruction; and
a processor, configured to call the program instruction stored in the memory, and execute, according to an obtained program:
allocating resource of a transmission configuration indication (TCI) state, and determining TCI state resource allocation information; and
notifying a terminal of the TCI state resource allocation information by notifying a correspondence relationship between the TCI state and a preset resource allocation pattern;
wherein the preset resource allocation pattern comprises: at least first one RBG or RB being a group of resources, and the other RBGs or RBs being another group of resources.
6. A resource determination apparatus, comprising:
a memory, configured to store a program instruction; and
a processor, configured to call the program instruction stored in the memory, and execute the method of claim 2 .
7. The apparatus according to claim 6 , wherein the processor determines the size of the PRG in the following manners:
when downlink control information sent by the network side indicates that a value of the size of the PRG is taken from set 1, and the set 1 is {2, a continuously scheduled bandwidth} or {4, the continuously scheduled bandwidth}:
for any TCI state:
if resources corresponding to the any TCI state are continuous and greater than or equal to BWP/4, or, resources corresponding to the any TCI state are continuous, and a sum of sizes of resources corresponding to a plurality of TCI states exceeds BWP/2, the size of the PRG is a size of the resources corresponding to the any TCI state, wherein BWP is a preset part of a bandwidth;
otherwise, the size of the PRG is a value other than “the continuously scheduled bandwidth” in the set 1.
8. The apparatus according to claim 6 , wherein a precoding manner in the resources with the size of the PRG is kept unchanged.
9. A non-transitory computer storage medium, storing a computer-executable instruction, wherein the computer-executable instruction is configured to make a computer execute the method according to claim 1 .
10. A non-transitory computer storage medium, storing a computer-executable instruction, wherein the computer-executable instruction is configured to make a computer execute the method according to claim 2 .
