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: This application provides a data transmission method. The method includes: A terminal device receives indication information from a network device, where the indication information includes a bit sequence, a value of an ith bit in the bit sequence indicate a usage status of an ith logical channel in M logical channels associated with a radio bearer, and a duplication transmission function is configured for the radio bearer; the terminal device transmits data based on the indication information through at least one logical channel associated with the radio bearer; and because the M logical channels are sorted based on IDs of cell groups associated with the M logical channels and IDs of the M logical channels, the ith bit in the bit sequence included in the indication information indicates the usage status of the ith logical channel in the M logical channels.

Abstract: A method includes: triggering, by a terminal device, a scheduling request (SR); in response to determining that a physical uplink control channel (PUCCH) carrying the SR and a physical uplink shared channel (PUSCH) carrying a first data packet overlap in time domain of a first uplink resource and a processing status of the PUSCH on the first uplink resource is processing completed, sending, based on the processing status of the PUSCH on the first uplink resource, the PUCCH on an overlapping time domain resource. According to the method, when the PUCCH carrying the SR and the PUSCH overlap in time domain of the first uplink resource, the terminal device considers the processing status of the PUSCH on the first uplink resource, and may determine, based on the processing status of the PUSCH on the first uplink resource, to send the PUCCH or the PUSCH on the overlapping time domain resource.

Abstract: A network access method and an apparatus relate to the field of communications technologies, and are used to support an industrial terminal in accessing a network when an architecture in which a control node sinks is used in a communications network. The method includes: An access network device sends an access list of a cell, where the access list of the cell includes at least one MAC address or group identifier. The access network device receives a message 3 sent by a terminal, where the message 3 includes a MAC address or a group identifier of the terminal. The access network device determines, depending on whether the MAC address or the group identifier of the terminal exists in the access list of the cell, whether the terminal can access the cell. This application is applicable to a process in which a terminal accesses a network.

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.
