Abstract: A transmission mode selection method and a device are provided. The method includes: determining first indication information, where the first indication information is used to indicate a changed transmission mode and/or indicate to change a transmission mode; and sending the first indication information to a terminal device. There may be a plurality of transmission modes for transmitting a data packet duplicated at a PDCP layer, in other words, there may be a plurality of modes for PDCP duplication. A transmission mode can be selected by using the first indication information. For example, when reliability of a mode for PDCP duplication is not high, another transmission mode can be selected by using the first indication information. In this way, a reliability requirement of a service is met as much as possible, thereby improving transmission quality of the service.

Abstract: Embodiments of this disclosure provide a paging method and an associated communication apparatus, medium, and chip. According to embodiments of this disclosure, an access network device sends information including an address of the access network device and an identifier of a terminal device to a core network device. The core network device determines an area for paging based on the address of the access network device, and sends a paging message including the identifier of the terminal device to the access network device. The access network device sends a radio access network paging message to the terminal device. In this manner, the area in which paging needs to be performed by the core network device can be reduced, thereby avoiding a waste of unnecessary paging resources.

Abstract: Embodiments of this application provide a communication method and an apparatus, relate to the communication field, and in particular, are applicable to a broadcast system. The method includes: A terminal device receives a first downlink channel from an access network device, where the first downlink channel is scrambled by using a first identifier and is used to carry first data. The terminal device receives a second downlink channel from the access network device, where the second downlink channel is scrambled by using a second identifier and is used to retransmit the first data. The first identifier and the second identifier are identifiers configured by the access network device. This method can implement a feedback retransmission mechanism combining broadcast initial transmission and partial retransmission, to further improve spectral efficiency of a communication system.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.
