  • Patent number: 11831446
    Abstract: The present disclosure relates to a method and an apparatus of transmitting a hybrid automatic repeat request-acknowledgement/negative acknowledgement (HARQ-ACK/NACK). A first set of HARQ-ACK/NACK including at least one timing value is identified. The at least one HARQ-ACK/NACK timing value is a time difference between a downlink time unit in which a physical downlink shared channel (PDSCH) is received and an uplink time unit in which a HARQ-ACK/NACK associated with the PDSCH is transmitted. A second set including at least one downlink time associated with a HARQ-ACK/NACK feedback is determined based on the first set. A codebook for the HARQ-ACK/NACK is generated based on a size of the codebook. The size of the codebook is identified based on the second set including the at least one downlink time. The codebook for the HARQ-ACK/NACK is transmitted to the base station in the uplink time unit.

  • Publication number: 20230370211
    Abstract: A method and an apparatus are provided for transmitting a hybrid automatic repeat request-acknowledgment/negative acknowledgment (HARQ-ACK/NACK). A first set including at least one HARQ-ACK/NACK timing value is identified. Each timing value indicates a time difference between a downlink time unit for physical downlink shared channel (PDSCH) reception and an uplink time unit in which a HARQ-ACK/NACK feedback is transmitted. A second set is determined that includes at least one downlink time unit. A codebook is generated for the HARQ-ACK/NACK feedback. A size of the codebook is identified based on a size of the second set and a number of HARQ-ACK/NACK bits corresponding to each downlink time unit. The codebook is transmitted to the base station. The number of HARQ-ACK/NACK bits is determined based on a number of code block groups (CBGs) in one transmission block (TB), in case that scheduling for a downlink transmission is based on CBG.

  • Publication number: 20230328695
    Abstract: A wireless communication method and a terminal device are provided, capable of avoiding data transmission problems due to hidden nodes and half-duplex in sidelink transmission. The method includes: transmitting, by a first terminal when a specific condition is satisfied, a reference resource set to a second terminal, the reference resource set being used by the second terminal to select a sidelink resource. It can reduce the burden on the second terminal due to the complexity in resource selection by the second terminal when the second terminal receives reference resource sets transmitted from too many terminals. The first terminal only transmits the reference resource set under a specific condition, which is advantageous in that the first terminal only reports the determined reference resource set to the terminal for which the reference resource set has the highest reference value, so as to improve the reliability of subsequent data transmission.

  • Patent number: 11758496
    Abstract: Provided are a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT), with a transmission and receipt processing method and device for time-frequency synchronization between V2X terminals. When a synchronization signal to be transmitted is identical to a synchronization signal of an existing D2D terminal, time-frequency resources configured for the D2D terminal in a cell are reused to transmit the synchronization signal. When synchronization signal to be transmitted is different from a synchronization signal of an existing D2D terminal, reconfigured time-frequency resources are used to transmit the synchronization signal. The synchronization signal transmitted by a V2X terminal indicates a corresponding synchronization source type by using a value of an SLSS sequence index and/or a value of a PSBCH specified field.
