Abstract
A method and apparatus for transmitting and receiving sidelink feedback information. The method includes: receiving, by a terminal equipment, DCI with CRC being scrambled by a SL-RNTI or a SL-CS-RNTI; generating first indication information used for indicating that the first sidelink transmission is successful or that a network device is not needed to schedule retransmission, wherein the first sidelink transmission is not performed on the dynamic grant resource scheduled by the DCI, and a priority of the first indication information is preconfigured; and transmitting the first indication information via a first PUCCH indicated by the DCI.
Claims20
An apparatus for transmitting sidelink feedback information, comprising:
- a receiver configured to receive downlink control information with cyclic redundancy check being scrambled by a sidelink radio network temporary identifier or a sidelink configuration scheduling radio network temporary identifier,
- the downlink control information including resource information and being used for a dynamic grant to schedule a terminal equipment to perform first sidelink transmission by using a dynamic grant resource according to the resource information;
- processor circuitry configured to generate acknowledgment (ACK) when the first sidelink transmission is not performed on the dynamic grant resource provided by the downlink control information;
- and
- a transmitter configured to transmit the acknowledgment (ACK) via a first physical uplink control channel.
An apparatus for receiving sidelink feedback information, comprising:
- a transmitter configured to transmit downlink control information with cyclic redundancy check being scrambled by a sidelink radio network temporary identifier or a sidelink configuration scheduling radio network temporary identifier,
- the downlink control information including resource information and being used for a dynamic grant to schedule a terminal equipment to perform sidelink transmission by using a dynamic grant resource according to the resource information;
- and
- a receiver configured to receive acknowledgment (ACK) transmitted via a physical uplink control channel wherein the acknowledgment (ACK) is generated by the terminal equipment when the sidelink transmission is not performed on the dynamic grant resource provided by the downlink control information.
A communication system, comprising:
- a terminal equipment configured to:
- receive downlink control information with cyclic redundancy check being scrambled by a sidelink radio network temporary identifier or a sidelink configuration scheduling radio network temporary identifier,
- the downlink control information including resource information and being used for a dynamic grant to schedule a terminal equipment to perform first sidelink transmission by using a resource according to the dynamic grant resource information,
- generate acknowledgment (ACK) when the first sidelink transmission is not performed on the resource provided by the downlink control information, and
- transmit the acknowledgment (ACK) via a physical uplink control channel;
- and
- a network device configured to transmit the downlink control information and receive the acknowledgment (ACK).
