Abstract: Embodiments of this application provide a synchronization signal sending method and apparatus. The method includes: obtaining an initial synchronization sequence, where a spectrum width corresponding to the initial synchronization sequence is greater than a bandwidth of a synchronization channel and is less than a sum of the bandwidth of the synchronization channel and a system protection bandwidth; dividing the initial synchronization sequence into N sub-synchronization sequences; carrying the N sub-synchronization sequences on N time-domain symbols; and sending the N time-domain symbols to a receiving apparatus. According to the synchronization signal sending method provided in the embodiments of this application, a bandwidth loss of a synchronization signal is reduced, and utilization and synchronization performance of a system synchronization bandwidth are improved.

Abstract: An apparatus includes a processor, and a non-transitory computer-readable storage medium coupled to the processor, and configured to store programmable instructions. When executed by the processor the programmable instructions cause the apparatus to maintain a transmission status of a previous data packet of a first access stratum entity, and adjust a transmission parameter of a current data packet, in response to the transmission status of the previous data packet being a transmission failure.

Abstract: A buffer status report processing method and an apparatus are disclosed. A network device determines a logical channel or a logical channel group for which a separate buffer status report BSR needs to be reported, and sends separate-BSR reporting indication information. A terminal device receives the separate-BSR reporting indication information sent by the network device, and reports the separate BSR for the logical channel or the logical channel group indicated in the separate-BSR reporting indication information. The network device receives the separate BSR reported by the terminal device, and determines, based on the separate BSR, uplink buffer data amount information corresponding to the logical channel or the logical channel group. According to the BSR processing method, resource scheduling accuracy of the network device is improved.

Abstract: Example communication message sending methods and apparatus based on backoff duration are described. One example method includes that a terminal device sends an access request to a cell to which the terminal device belongs. The terminal device monitors a downlink control channel, and receives an access response message based on scheduling information on the downlink control channel. If the access response message carries a backoff access identifier, the terminal device determines a backoff parameter corresponding to the backoff access identifier in the access response message based on a correspondence that is pre-stored and that is between the backoff access identifier and the backoff parameter. The terminal device determines backoff duration based on the backoff parameter and an access resource interval period corresponding to the terminal device, and sends an access request to the cell after the backoff duration.
