Abstract: Embodiments of this application provide a communication method and apparatus, and a computer storage medium, to reduce communication latency between a terminal and a base station, and improve a capability of adapting to a latency-sensitive scenario. The method provided in this application includes a terminal that receives at least one uplink configuration and at least one random access configuration from a network device. The uplink configuration is used to indicate a parameter for sending uplink data, and the random access configuration is used to indicate a parameter for sending a preamble. The at least one uplink configuration includes a first uplink configuration, the at least one random access configuration includes a first random access configuration, and there is a correspondence between the first uplink configuration and the first random access configuration.

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: Example data sending methods and apparatus are described. One example method includes sending a first message to a network device by a terminal device. The first message is used to indicate information about remaining time of each of one or more data packets. The remaining time of each of the one or more data packets is used to indicate that the terminal device needs to finish sending each of the one or more data packets before the end of the remaining time. The terminal device obtains information about a resource configured by the network device for the terminal device, wherein the resource is used to send each of the one or more data packets before the end of the remaining time.

Abstract: This application provides a method and a corresponding apparatus. One example method includes: A transmitting side receives an RLC status report from a receiving side, where the RLC status report includes at least one piece of status information, each of the at least one piece of status information indicates one or more receiving statuses of one or more consecutive RLC service data units (SDUs) that are not successfully received, and the at least one piece of status information is sequentially sorted in ascending order of RLC SDU sequence numbers (SNs) in the RLC status report; and if the last piece of status information in the RLC status report indicates that a part of data of a first RLC SDU is lost, the transmitting side determines, based on the RLC status report, whether a receiving status of the first RLC SDU is completely reflected in the RLC status report.

Abstract: Embodiments of this application provide a data transmission method and an apparatus. When a time-frequency resource used by a terminal device for data transmission is unavailable, the terminal device postpones, based on indication information of a network device and/or according to a postponement rule, the data transmission to a time-frequency resource closest to the time-frequency resource. Therefore, a data transmission latency is reduced.
