Abstract

The invention discloses a signal channel detecting method, a client end and a base station. The method comprises the following steps: a signal channel detecting mechanism of a channel detecting deviceis determined when random access on an unlicensed frequency spectrum, and at least one signal channel detection parameter with a high priority among signal channel detection parameters of a signal channel where the unlicensed frequency spectrum is located; the at least one channel detection parameter of the signal channel where the unlicensed frequency spectrum is located is detected according tothe signal channel detection mechanism; detecting operation is performed according to a priority order of the channel detection parameters, success rates of idle signal channel detection are improved, and therefore the client end can smoothly perform random access on the unlicensed frequency spectrum; delay can be reduced, and success rates of random access on the unlicensed frequency spectrum can be improved.

Description

technical field [0001] The present invention relates to the technical field of channel detection, in particular to a channel detection method, a client terminal and a base station. Background technique [0002] The client UE obtains the information parameter: SSB-per-rach-occasion (the number of synchronization signal block SSBs mapped on each random access opportunity RO, and the value is {1 / 8, 1 / 4, 1 / 2, 1, 2, 4, 8, 16}), prach-FDM (the number of ROs multiplexed in the frequency domain at the same time, the value is {1, 2, 4, 8}) and the number of SSBs actually sent to determine the mapping between SSBs and ROs relation. [0003] When the UE initiates RACH (random access), it is usually CBRA (contention-based RACH, contention-based random access). According to the SSB it accesses and the above information, it can know the time-frequency domain of the RO that can send the preamble Location. [0004] For random access on the unlicensed spectrum, the UE needs to perform cha...
