摘要： A method and apparatus for data transmission are provided, which can accurately determine a transport block size (TBS) for a data channel in sidelink (SL) transmission, thereby improving transmission performance. The method includes the following. A terminal device determines number of resource elements (REs) for a physical sidelink shared channel (PSSCH) in a second resource according to a first resource used for transmitting a physical sidelink control channel (PSCCH) and the second resource used for transmitting the PSSCH, where the first resource at least partially overlaps with the second resource. The terminal device determines a TBS for the PSSCH according to the number of the REs for the PSSCH.

摘要： 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. On one hand, 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. On the other hand, 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.

摘要： Communication methods and devices for a sidelink (SL) are provided. A communication method for an SL includes the following. A first terminal device obtains a first transmission resource. The first terminal device sends first feedback information to a second terminal device, by using the first transmission resource. A time unit in which the first transmission resource is located is not used for transmitting data by the first terminal device to at least one third terminal device, where the first terminal device, the second terminal device, and the at least one third terminal device belong to a first group. By means of the above communication methods and devices for an SL, it is possible to send feedback information in groupcast communication.
