This application provides an extended reality data transmission method and an apparatus. The method includes: determining that a data type is extended reality data; determining, based on the data type, to obtain, based on delay information and transmission error information, extended reality quality indicator XQI information corresponding to a target rate, where the XQI information indicates transmission quality of the extended reality data; and performing communication based on the XQI information.

Extended reality data transmission method and apparatus

A communication method includes receiving, by a first communication apparatus, indication information from a second communication apparatus, and determining, by the first communication apparatus, a first quality of service (QoS) of the extended reality (XR) service based on the at least one piece of QoS of an XR service. The first communication apparatus is a core network device or an access network device. The indication information is useable to indicate at least one piece of QoS of the XR service. The XR device receives data of the XR service or sends data of the XR service by a terminal device. The second communication apparatus is an XR server or a chip in the XR server.

Communication method and apparatus

A data processing method and a related apparatus are disclosed, to improve data recovery effects in various packet loss scenarios. The method includes: determining a packet loss scenario type corresponding to a first data packet when detecting that the first data packet is lost in a data packet transmission process (); generating a second data packet based on a data packet adjacent to the first data packet if the packet loss scenario type corresponding to the first data packet meets a data packet compensation condition (); and finally adding the second data packet to a corresponding target location at which the first data packet is located before the first data packet is lost, that is, using the second data packet to compensate for the lost first data packet ().

Data processing method and related apparatus

This application provides a data transmission method and apparatus. The method includes: obtaining significant bits in an Ndata frame, where N is an integer greater than or equal to 1, a quantity of the significant bits in the Ndata frame is smaller than a quantity of bits in the Ndata frame, and remaining bits other than the significant bits in the Ndata frame are insignificant bits in the Ndata frame; and sending the significant bits in the Ndata frame, and skipping sending the insignificant bits in the Ndata frame. According to the application, on a premise of ensuring voice intelligibility, a transmit end apparatus transmits only the significant bits, to minimize a data transmission amount, thereby improving transmission reliability and coverage.

Data transmission method and apparatus

The present disclosure relates to data processing methods and devices. One example method includes obtaining N correctly received radio link control (RLC) protocol data units (PDUs) in a packet data convergence protocol (PDCP) PDU, and generating the PDCP PDU based on the N correctly received RLC PDUs, where the PDCP PDU includes M RLC PDUs, N and M are positive integers, and N&#x3c;M.
