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 communication method includes determining, by a terminal side device, that a consistent uplink listen before talk (LBT) failure occurs in a first bandwidth part (BWP) of a cell. The communication method also includes canceling, by the terminal side device, a consistent uplink LBT failure status of the cell in response to a determination by the terminal side device to switch to a second BWP of the cell.

Abstract: This application provides a random access method and apparatus. The method includes: A terminal device receives first information sent by a network device, where the first information includes a priority value of a first parameter used for a random access procedure. The terminal device initiates the random access procedure based on the priority value. In this way, the terminal device can preferentially select, based on the priority value of the first parameter, a two-step random access procedure or send a message in the random access procedure by using high power, to quickly access a network and reduce an access delay.

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: A data integrity protection method and apparatus in a network environment are described. A terminal device obtains an integrity protection algorithm and a key corresponding to a session or a flow, and a DRB corresponding to the session. The terminal device performs, by using the integrity protection algorithm and the key corresponding to the session, integrity protection on data of the DRB corresponding to the session or the flow, where one session includes a plurality of flows. Different integrity protection algorithms and keys can be used for different sessions, and different integrity protection algorithms and keys can also be used for different flows. In this way, integrity protection is more flexible and meets security requirements of a same user for different services.

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.
