Abstract: Embodiments of this application disclose a resource allocation method, a base station, and a terminal. The method includes: A base station sends a configuration message to a terminal, where the configuration message is used to configure, for the terminal, a random access channel RACH resource used in a channel occupancy time COT. The base station receives a random access request that is sent by the terminal based on the RACH resource allocated by using the configuration message. According to embodiments of this application, a random access latency of the terminal can be reduced.

Abstract: A channel access method is provided. Under the method, a network element performs random backoff listen before talk (LBT) for channel preemption, and after the preemption succeeds, performs signal transmission in the first transmission time interval TTI within a maximum channel occupancy time MCOT. The network element also performs nonrandom backoff LBT for channel preemption before another at least one TTI within the maximum channel occupancy time MCOT.

Abstract: A method for accessing an access point by a station device, a device, and a system. A station device selects a master access point from multiple access points according to channel quality and accesses the master access point, and sends information about remaining access points to the master access point, so that the master access point selects a slave access point according to the information about the remaining access points.

Abstract: Embodiments of the present invention provides a method and an apparatus for channel access for the transmission of a signal. The method includes: counting down, by a first device, an initial value N of a random backoff counter within a contention window; sensing, by the first device, a channel status; determining, by the first device, whether or not to perform transmission of the signal within a periodic window based on the sensed channel status; transmitting, by the first device, the signal after sensing the channel to be idle. Therefore, the channel access method and apparatus adapt to the data and control traffic load in the channel using LBT with random back-off with a contention window of variable size.
