摘要： This application provides an uplink carrier handover method, a network device, and a terminal device. The method includes: obtaining, by a network device, target measurement information, where the network device communicates with a terminal device in a current cell by using a first uplink carrier and a second uplink carrier; determining, by the network device, based on the target measurement information, whether the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier; and when the terminal device needs to be handed over from the first uplink carrier to the second uplink carrier, sending, by the network device, handover instruction information to the terminal device. In the embodiments of this application, the network device may determine, by using the target measurement information, whether the terminal device needs to perform the uplink carrier handover. When the terminal device needs to perform the handover, the network device instructs, by using the handover instruction information, the terminal device to perform the uplink carrier handover. Therefore, an uplink carrier on which the terminal device needs to work can be determined more accurately and reliably, ensuring normal communication between the terminal device and the network device.

摘要： Embodiments of the present invention provide a time service method, a terminal device, and a network device. The method includes: determining, by a terminal device, a first moment of a first downlink message, and determining a second moment of the first downlink message; determining, by the terminal device, a third moment of a first uplink message, and determining a fourth moment of the first uplink message; and determining, by the terminal device, a time offset between the terminal device and the network device based on the first moment, the second moment, the third moment, and the fourth moment. According to the method provided in the embodiment of the present invention, uplink and downlink propagation delays are considered for the terminal device, and a time service based on absolute time can be provided for the terminal device by using the first moment and the second moment of the first downlink message and the third moment and the fourth moment of the first uplink message, thereby effectively reducing a time service error.

摘要： Embodiments of the present invention relate to the field of communications technologies, and disclose a method and an apparatus for recovering from a radio downlink failure. The method includes: monitoring a first radio link to determine whether a radio downlink failure occurs on the first radio link, where the first radio link is a currently connected radio link; if it is detected that the radio downlink failure occurs on the first radio link, starting a physical-layer-monitored automatic-recovery process for the first radio link and starting a Radio Link Control RRC connection re-setup process to set up a second radio link; and recovering from the radio downlink failure through either of the physical-layer-monitored automatic-recovery process and the RRC connection re-setup process. In this way, the physical-layer-monitored automatic-recovery process is prevented from consuming relatively long time when the radio link cannot automatically recover, to reduce recovery time, thereby meeting a latency requirement of an ultra-reliable and low latency service.

摘要： 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.

摘要： This application relates to wireless communications technologies, and in particular, to a random access device, method, and system, so as to resolve a problem that control channels become limited in random access procedures. In a network device provided in this application, a processing module is configured to determine a same processing result for random access procedures initiated by N terminal devices in M terminal device sets, where M and N are positive integers; and a sending module is configured to send a same random access control message to the N terminal devices, where the random access control message is used to indicate the same processing result determined by the processing module, the message includes terminal set identification information, and the terminal set identification information is used to identify the N terminal devices. The network device uses a same random access reject message to indicate the same processing result for the random access procedures to the N terminal devices. This can reduce control channel resources occupied for sending random access reject messages, and resolve a problem that control channels become limited in random access procedures.
