摘要: Embodiments of this application provide a buffer status report (BSR) sending method, a terminal device, and a network device. The method includes: determining a first resource configured for a first channel; adding, a first cyclic redundancy check (CRC) to a BSR; and sending a second channel on the first resource, or sending the first channel and a second channel on the first resource, where the second channel is used to carry the BSR to which the first CRC is added. Based on the embodiments of this application, the terminal device independently adds the first CRC to the BSR, and sends the second channel carrying the BSR to a network device, so that the network device learns arrival of data corresponding to the second channel at the terminal device. Therefore, the network device can pre-configure a resource for the data, thereby reducing a transmission latency of the data.

摘要: The present disclosure provides an information processing method and apparatus. A terminal device encodes uplink control information (UCI) to obtain coded bits of the UCI, and encodes data to obtain coded bits of the data. The terminal device multiplexes the coded bits of the UCI and the coded bits of the data to obtain a multiplexed bit sequence. The terminal device then transmits the multiplexed bit sequence to a network device via a physical uplink shared channel (PUSCH). A length of a transmission time interval of the UCI is less than or equal to 0.5 millisecond. In this way, data transmission latency can be reduced.

摘要: Embodiments of the present disclosure provide a data communication method, a terminal device, and a network device. In the solution, a terminal device receives first indication information in a first time period; and the terminal device transmits first information in a second time period, where a duration of the first time period is a first time unit, a duration of the second time period is a second time unit, and a duration of the second time unit is greater than a duration of the first time unit. In this way, although the terminal device receives the first indication information in a first time unit N, the terminal device transmits the first information in a second time unit M whose duration is greater than that of the first time unit.
