Abstract
Embodiments of the present disclosure relate to devices, methods and a medium for sidelink communications. In an aspect, a terminal device receives, from a network device, configuration information indicating at least one set of candidate starting positions for a cyclic prefix extension (CPE). The at least one set of candidate starting positions are determined based on a listen before talk (LBT) type. Then, the terminal device determines, based on the configuration information, to perform or skip a data transmission on a symbol within a slot occupied by the terminal device for a sidelink transmission. In this way, the sidelink communication performance can be improved.
Claims21
A terminal device for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory and configured to cause the terminal device to:
- receive, from a network device, configuration information indicating at least one set of candidate starting positions for a cyclic prefix extension (CPE), wherein the at least one set of candidate starting positions are determined based on a listen before talk (LBT) type;
- and
- determine, based on the configuration information, to perform or skip a data transmission on a symbol within a slot occupied by the terminal device for a sidelink transmission.
A terminal device for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the terminal device to:
- receive, from a network device, configuration information indicating at least one set of candidate starting positions for cyclic prefix extension (CPE), wherein the at least one set of candidate starting positions are determined based on a listen before talk (LBT) type;
- determine a target LBT type based on a resource configuration for the terminal device or a received control channel transmission;
- and
- select, based on the target LBT type and the configuration information, a target starting position from the at least one set of candidate starting positions for occupying a sidelink channel.
A network device for wireless communication, comprising:
- at least one memory;
- and
- at least one processor coupled with the at least one memory and configured to cause the network device to:
- determine at least one set of candidate starting positions for cyclic prefix extension (CPE) based on a listen before talk (LBT) type;
- and
- transmit, to at least one terminal device, configuration information indicating the at least one set of candidate starting positions for CPE.
A method performed by a terminal device, the method comprising:
- receiving, from a network device, configuration information indicating at least one set of candidate starting positions for a cyclic prefix extension (CPE), wherein the at least one set of candidate starting positions are determined based on a listen before talk (LBT) type;
- and
- determining, based on the configuration information, to perform or skip a data transmission on a symbol within a slot occupied by the terminal device for a sidelink transmission.
