Methods, devices and computer readable media for communications on a sidelink
Embodiments of the present disclosure relate to methods, devices and computer readable media for communications. A method comprises determining, at a first terminal device, whether to obtain information about candidate resources for a sidelink transmission. The method further comprises in response to a determination that the information is to be obtained, receiving the information from a second terminal device. The method further comprises determining target resources for performing the sidelink transmission based on the information.
1 . A first terminal comprising:
a memory; and
a processor configured to:
receive, from a second terminal, via a Physical Sidelink Feedback Channel (PSFCH), information about a slot in which the second terminal does not expect to perform reception on a sidelink due to half-duplex operation,
wherein the first terminal is an intended receiver of the second terminal for a resource of a Physical Sidelink Shared Channel (PSSCH) transmission; and
determine a target resource of a transmission of the sidelink from the first terminal to the second terminal by excluding the slot.
2 . A second terminal comprising:
a memory; and
a processor configured to:
transmit, to a first terminal, via a Physical Sidelink Feedback Channel (PSFCH), information about a slot in which the second terminal does not expect to perform reception on a sidelink due to half-duplex operation,
wherein the first terminal is an intended receiver of the second terminal for a resource of a Physical Sidelink Shared Channel (PSSCH) transmission; and
receive a transmission of the sidelink from the first terminal to the second terminal using a target resource determined by excluding the slot.
3 . A method comprising:
receiving, from a second terminal, via a Physical Sidelink Feedback Channel (PSFCH), information about a slot in which the second terminal does not expect to perform reception on a sidelink due to half-duplex operation,
wherein the first terminal is an intended receiver of the second terminal for a resource of a Physical Sidelink Shared Channel (PSSCH) transmission; and
determine a target resource of a transmission of the sidelink from a first terminal to the second terminal by excluding the slot.
4 . A method comprising:
transmitting, to a first terminal, via a Physical Sidelink Feedback Channel (PSFCH), information about a slot in which a second terminal does not expect to perform reception on a sidelink due to half-duplex operation,
wherein the first terminal is an intended receiver of the second terminal for a resource of a Physical Sidelink Shared Channel (PSSCH) transmission; and
receiving a transmission of the sidelink from the first terminal to the second terminal using a target resource determined by excluding the slot.
