Abstract: This application provides a scheduling request processing method and an apparatus. The method includes: determining, by a terminal device, that a condition for triggering a scheduling request SR of a first service is met; determining, by the terminal device, whether a priority of the first service is higher than a priority of a second service for which a scheduling request SR has been triggered or has been sent; and when determining that the priority of the first service is higher than the priority of the second service, triggering and/or sending, by the terminal device, the SR of the first service.

Abstract: A segment retransmission method includes: if a receiving RLC function entity has not received, within a preset time period, all segments of a data packet identified by a serial number, the receiving RLC function entity sends a retransmission request to a sending party, where the retransmission request includes the serial number, to request the sending party to retransmit an unreceived segment of the data packet identified by the serial number, and thus reduces an average data packet transmission latency.

Abstract: This application provides a data transmission method. In the method, a first access network device and a second access network device establish a data radio bearer (DRB)-based tunnel and a session-based tunnel. The second access network device sends a Packet Data Convergence Protocol (PDCP) layer data packet to the first access network device via the DRB-based tunnel; and the second access network device sends a Service Data Adaptation Protocol (SDAP) layer data packet to the first access network device via the session-based tunnel.

Abstract: Embodiments of this application relate to the communications field, and provide an uplink control information transmission method and an apparatus, to effectively ensure that when user equipment has both a PUCCH resource and a PUSCH resource, UCI can be transmitted to a base station. The method includes: pre-configuring, by user equipment, first uplink control information UCI and second UCI, where the first UCI is carried on a PUSCH resource of a first cell for transmission, the second UCI is carried on a PUCCH resource for transmission, and the first cell is a cell on which CCA or LBT detection needs to be performed; and sending, by the user equipment, the first UCI or the second UCI to a base station. The method and the apparatus are used for UCI transmission.
