Title: LOAD-BASED LBT CHANNEL DETECTION METHOD AND SYSTEM, BASE STATION, AND TERMINAL
Abstract:
The present invention provides a load-based LBT channel detection method, a load-based LBT channel detection system, a base station, and a terminal. The load-based LBT channel detection method comprises: when detecting that a channel is busy in an initial CCA channel detection time or in a current ECCA detection granularity of an ECCA channel detection time of load-based LBT channel detection, configuring M defer periods after the initial CCA channel detection time or the current ECCA detection granularity; and carrying out the load-based LBT channel detection in the M defer periods by using the defer periods as a granularity, M being an integer greater than or equal to 1. By means of the technical solution of the present invention, a defer period (defer period) can be accurately defined, so that different defer periods can be configured for different sending objects, and different channel occupation probabilities can be realized, thereby improving the channel detection efficiency.
