Method and apparatus for managing resource pool in wireless communication system

Abstract

A method of performing communication by a user equipment (UE) includes identifying a time division duplexing (TDD) configuration for uplink slots, a resource pool configuration for sidelink slots, and a physical sidelink shared channel (PSSCH) configuration for sidelink symbols; determining at least one part of a slot based on a result of the identification; and transmitting a PSSCH based on the determined at least one part of the slot.

What is claimed is: 
     
         1 . A method of performing communication, by a user equipment (UE), the method comprising:
 identifying a time division duplexing (TDD) configuration for uplink slots, a resource pool configuration for sidelink slots, and a physical sidelink shared channel (PSSCH) configuration for sidelink symbols;   determining at least one part of a slot based on a result of the identification; and   transmitting a PSSCH based on the determined at least one part of the slot.   
     
     
         2 . The method of  claim 1 , wherein identifying the resource pool configuration further comprises:
 identifying a range of a bitmap for a resource pool based on a maximum range to which the resource pool is repeatedly applied.   
     
     
         3 . The method of  claim 2 , further comprising:
 determining the maximum range to which the resource pool is repeatedly applied based on a subcarrier spacing.   
     
     
         4 . The method of  claim 1 , wherein determining the at least one part of the slot further comprises:
 determining a subset including continuous symbols in the slot, based on the PSSCH configuration,   wherein the PSSCH is transmitted based on the subset of the slot.   
     
     
         5 . The method of  claim 1 , wherein information of the TDD configuration is received through a physical sidelink broadcast channel (PSBCH). 
     
     
         6 . A method of performing communication, by a base station (BS), the method comprising:
 determining slots allocated for uplink (UL) transmission;   transmitting time division duplexing (TDD) configuration information indicating the slots for the UL transmission;   transmitting a system information block (SIB) for a sidelink including a bitmap indicating a slot as a resource pool of a user equipment (UE); and   transmitting a physical sidelink shared channel (PSSCH) configuration for sidelink symbols,   wherein a PSSCH is transmitted, at the UE, based on the sidelink symbols of the slot.   
     
     
         7 . The method of  claim 6 , wherein a range of the bitmap for the resource pool is identified based on a maximum range to which the resource pool is repeatedly applied. 
     
     
         8 . The method of  claim 7 , wherein the maximum range to which the resource pool is repeatedly applied is based on a subcarrier spacing. 
     
     
         9 . The method of  claim 7 , wherein a subset including continuous symbols in the slot, is determined based on configured resource pool information at the UE for the transmission of the PSSCH. 
     
     
         10 . A user equipment (UE) for performing communication, the UE comprising:
 a transceiver; and   at least one processor coupled with the transceiver and configured to:   control the transceiver to identify a time division duplexing (TDD) configuration for uplink slots, a resource pool configuration for sidelink slots, and a physical sidelink shared channel (PSSCH) configuration for sidelink symbols,   determine at least one part of a slot based on a result of the identification, and   control the transceiver to transmit a PSSCH based on the determined at least one part of the slot.   
     
     
         11 . The user equipment of  claim 10 , wherein the at least one processor is further configured to:
 identify a range of a bitmap for a resource pool based on a maximum range to which the resource pool is repeatedly applied.   
     
     
         12 . The user equipment of  claim 11 , wherein the at least one processor is further configured to:
 determine the maximum range to which the resource pool is repeatedly applied based on a subcarrier spacing.   
     
     
         13 . The user equipment of  claim 10 , wherein the at least one processor is further configured to:
 determine a subset including continuous symbols in the slot, based on the PSSCH configuration,   wherein the PSSCH is transmitted based on the subset of the slot.   
     
     
         14 . The user equipment of  claim 10 , wherein information of the TDD configuration is received through a physical sidelink broadcast channel (PSBCH). 
     
     
         15 . A base station (BS) for performing communication, the BS comprising:
 a transceiver; and   at least one processor coupled with the transceiver and configured to:   determine slots allocated for uplink (UL) transmission,   control the transceiver to transmit time division duplexing (TDD) configuration information indicating the slots for the UL transmission, and   control the transceiver to transmit a system information block (SIB) for a sidelink including a bitmap indicating a slot as a resource pool of a user equipment (UE),   wherein a physical sidelink shared channel (PSSCH) is transmitted, to the UE, based on sidelink symbols of the slot.   
     
     
         16 . The base station of  claim 15 , wherein a range of the bitmap for the resource pool is identified based on a maximum range to which the resource pool is repeatedly applied. 
     
     
         17 . The base station of  claim 16 , wherein the maximum range to which the resource pool is repeatedly applied is based on a subcarrier spacing. 
     
     
         18 . The base station of  claim 16 , wherein a subset including continuous symbols in the slot, is determined based on configured resource pool information at the UE for the transmission of the PSSCH.
