Abstract: A resource allocation method includes sending, by a network device, first information to user equipment, where the first information is used to indicate uplink resources corresponding to autonomous uplink transmission performed by the user equipment; and sending, by the network device, second information to the user equipment, where the second information is used to indicate a resource that is in the uplink resources and that is actually used by the user equipment to perform autonomous uplink transmission. The uplink resources corresponding to autonomous uplink transmission are allocated while resource utilization is ensured.

Abstract: A random access method and apparatus to increase an opportunity of performing physical random access channel (PRACH) access, where the method includes receiving, by a terminal, information about a PRACH time window from a base station, where the information about the PRACH time window carries a size of the PRACH time window, preempting, by the terminal, an unlicensed carrier on which a PRACH resource is configured, and performing, by the terminal before the size of the PRACH time window is exceeded, .PRACH access on the successfully preempted unlicensed carrier on which the PRACH resource is configured. Therefore, by configuring the PRACH time window, the terminal has more opportunities to preempt the unlicensed carrier on which the PRACH resource is configured, greatly improving a PRACH access success rate.

Abstract: A multi-link configuration method, a base station, and a user equipment, where the UE generates uplink information and sends the uplink information to the base station. The base station configures a first set or a second set for the UE based on the uplink information. In this process, the transmission point included in the first set is a candidate transmission point, and the transmission point included in the second set establishes a plurality of links to a user, and is a transmission point that actually transmits data to the UE. When a signal of the transmission point included in the second set is weak or interrupted, a transmission point with good quality is selected from the first set and added to the second set to reduce a quantity of times of link interruption and service interruption.
