Abstract: A beam failure recovery BFR method and an apparatus are provided. The method includes: A terminal receives indication information of a first threshold and a second threshold, where the second threshold is used to determine that a beam failure occurs on an access network device. The terminal collects statistics on quantities of beam failure instance times of one or more access network devices that communicate with the terminal based on beams in a cell; and performs beam recovery on an access network device whose quantity of beam failure instance times is greater than or equal to the first threshold and less than the second threshold. The method and the apparatus in this application can further reduce a possibility of the beam failure, improve network reliability, and avoid beam failures on a plurality of devices in the cell at the same time.

Abstract: A method includes receiving a first parameter set that is for establishing a relay radio link control RLC bearer and that is sent by a first terminal; and further receiving a first configuration message sent by a network device, where the first configuration message includes a second parameter set corresponding to the relay RLC bearer. The relay device establishes, based on the first parameter set received from the first terminal and the second parameter set obtained from the network device, a relay RLC bearer corresponding to a first link, where the first link is a link between the relay device and a second terminal.

Abstract: A wireless communication method includes receiving, by a terminal device, first information sent by a network device. The first information includes a first offset. The first offset is a difference between a frame number of a first system frame and a frame number of a first direct frame. The first system frame and the first direct frame overlap in a time domain. The wireless communication method also includes determining, by the terminal device, the first direct frame based on at least one of the first offset or the frame number of the first system frame.

Abstract: A communication method and an apparatus includes a network device sends first information to a terminal device, so that the terminal device can determine a HARQ feedback manner based on the first information, where the HARQ feedback manner includes skipping ACK feedback and/or NACK feedback. In this manner, the network device controls the HARQ feedback manner used by the terminal device, so that the terminal device can be flexibly controlled to use different HARQ feedback manners in different scenarios, to adapt to a service constraint, effectively reduce power consumption of the terminal device, and save air interface resources.

Abstract: A signal transmission method includes receiving configuration information from a network device. The configuration information is used to indicate a serving cell that is allowed or forbidden to be used by a terminal for a first service or first control information. The method also includes adjusting the serving cell that is allowed or forbidden to be used by the terminal for the first service or the first control information. The method further includes transmitting the first service or the first control information by using an adjusted serving cell.

Abstract: An Ethernet header compression method and apparatus and an Ethernet header decompression method and apparatus. After receiving an Ethernet frame including a first to-be-compressed field, a compression end compresses an Ethernet header of the Ethernet frame based on a first correspondence including first compression information and a value of the first to-be-compressed field and the first compression information. Correspondingly, a decompression end decompresses an Ethernet header of a compressed Ethernet frame based on the first correspondence when receiving the compressed Ethernet frame. In the embodiments of this application, because the Ethernet header of the Ethernet frame is compressed, communication resources is saved.

Abstract: According to embodiments of this application, a terminal device may indicate, to a network device, that at least two uplink grants are required for a to-be-sent data packet; or a terminal device sends, to a network device, indication information used to determine that at least two uplink grants are required for a to-be-sent data packet, so that the network device sends the at least two uplink grants for the to-be-sent data packet. Then, the terminal device assembles the to-be-sent data packet into at least two transport blocks, and sends the at least two transport blocks to the network device by using uplink resources indicated by the at least two uplink grants, to reduce a probability that the terminal device completely transmits the to-be-sent data packet at a time, thereby reducing continuous packet loss. This prevents a receiver manipulator from entering a deadlock state.
