Abstract: Embodiments of this application provide a multicast transmission control method. A terminal side device gives a feedback to an access network side device for a received multicast service, the feedback indicating that the terminal side device successfully receives the multicast service or fails to receive the multicast service, so that the access network side device can learn a status of the sent multicast service. This facilitates optimization of transmission of the multicast service.

Abstract: The present disclosure relates to information transmission methods. In one example method, a first network device or a second network device triggers a terminal device to be handed over from a first cell to a second cell. The terminal device sends second information, where the second information includes information about a radio link failure that occurs between the terminal device and the second cell, or information about beam failure recovery that occurs between the terminal device and the second cell. The first network device or the second network device performs mobility robustness optimization based on the second information.

Abstract: An information processing method and apparatus. The method includes: a terminal side device sends uplink information through a PUSCH; determines a monitoring identifier of a downlink control channel based on PUSCH resource information of a resource occupied by the PUSCH; further monitors the downlink control channel based on the monitoring identifier, where the downlink control channel carries information used to indicate a resource location of a PDSCH; and then receives the PDSCH at the resource location of the PDSCH, where the PDSCH carries a response message. In this way, the terminal side device avoids blindly monitoring, based on the monitoring identifier, a downlink control channel that does not belong to the terminal side device and parsing a corresponding response message, and power consumption of the terminal side device is reduced.

Abstract: The present disclosure relates to delay measurement methods and apparatus. In one example method, a first communications device receives a data unit from a second communications device, where the data unit includes time information, the time information is used to indicate a first moment at which the second communications device sends the data unit, and the time information indicates the first moment based on a part of bits of a frame number. The first communications device determines a delay from the second communications device to the first communications device based on the first moment and a second moment, where the second moment is a moment at which the first communications device receives the data unit.
