Abstract

Disclosed are methods, apparatuses, and systems for resource selection for a user equipment (UE) in a first sidelink communication. The method includes: determining, by a first sidelink communication module, a selection window; setting at least one first threshold parameter for a resource exclusion at the first sidelink communication module; initializing a candidate resource set; receiving, from a second sidelink communication module, at least one of: at least one second threshold parameter used for a resource exclusion at the second sidelink communication module, sidelink sensing information obtained by the second sidelink communication module, or resource reservation information collected by the second sidelink communication module; determining one or more final candidate resources in the first sidelink communication using the at least one first threshold parameter and the at least one information received from the second sidelink communication module; and reporting the determined one or more final candidate resources to a higher layer.

First claim

1 - 10 . (canceled)

11 . A user equipment (UE), the UE comprising:
a memory storing an instruction; and a processor configured to execute the instruction, for resource selection in a first sidelink communication, stored in the memory to:
set at least one first threshold parameter for a resource exclusion at the UE;
initialize one or more first candidate resources in the first sidelink communication;
determine one or more second candidate resources from among the one or more first candidate resources based on one or more resources not monitored by the UE due to the UE's own transmission or discontinuous reception (DRX) operation;
obtain, at least one of: at least one second threshold parameter used for a resource exclusion in second sidelink communication, sidelink sensing information in the second sidelink communication, or resource reservation information in the second sidelink communication;
determine one or more third candidate resources from among the one or more second candidate resources using the at least one first threshold parameter and the obtained at least one information in the second sidelink communication; and
report one or more fourth candidate resources to a higher layer for selection of one or more transmission resources in the first sidelink communication based on the one or more third candidate resources.

12 . The UE of claim 11 , wherein the processor is further configured to:
increase the at least one first threshold parameter by an increment if the number of the one or more third candidate resources is smaller than total number of the one or more first candidate resources multiplied by X, where the X is indicated by the information preconfigured by the network.

13 . The UE of claim 11 , wherein the processor is further configured to:
initialize a candidate resource set including one or more resources in the first sidelink communication, if the number of the one or more third candidate resources is smaller than total number of the one or more first candidate resources multiplied by X, where the X is indicated by the information preconfigured by the network.

14 . The UE of claim 11 , wherein the sidelink sensing information in the second sidelink communication comprises one or more sidelink measurement in the second sidelink communication.

15 . The UE of claim 14 , wherein the sidelink measurement in the second sidelink communication comprises sidelink reference signal received power (SL-RSRP) measurement in the second sidelink communication.

16 . A method for resource selection in a first sidelink communication by a user equipment (UE), comprising:
setting at least one first threshold parameter for a resource exclusion at the UE; initializing one or more first candidate resources in the first sidelink communication; determining one or more second candidate resources from among the one or more first candidate resources based on one or more resources not monitored by the UE due to the UE's own transmission or discontinuous reception (DRX) operation; obtaining, at least one of: at least one second threshold parameter used for a resource exclusion in second sidelink communication, sidelink sensing information in the second sidelink communication, or resource reservation information in the second sidelink communication; determining one or more third candidate resources from among the one or more second candidate resources using the at least one first threshold parameter and the obtained at least one information in the second sidelink communication; and reporting one or more fourth candidate resources to a higher layer for selection of one or more transmission resources in the first sidelink communication based on the one or more third candidate resources.

17 . The method of claim 16 , wherein the method further comprises:
increasing the at least one first threshold parameter by an increment if the number of the one or more third candidate resources is smaller than total number of the one or more first candidate resources multiplied by X, where the X is indicated by the information preconfigured by the network.

18 . The method of claim 16 , wherein the method further comprises:
initializing a candidate resource set including one or more resources in the first sidelink communication, if the number of the one or more third candidate resources is smaller than total number of the one or more first candidate resources multiplied by X, where the X is indicated by the information preconfigured by the network.

19 . The method of claim 16 , wherein the sidelink sensing information in the second sidelink communication comprises one or more sidelink measurement in the second sidelink communication.

20 . The method of claim 19 , wherein the sidelink measurement in the second sidelink communication comprises sidelink reference signal received power (SL-RSRP) measurement in the second sidelink communication.
