Abstract: Various embodiments provide a carrier switching method on an unlicensed spectrum, a base station, and a terminal device. In those embodiments, a base station may communicate with a terminal device by using a first carrier in an unlicensed spectrum by occupying, within a scheduling cycle, an anchor carrier and any one of a plurality of data carriers in the unlicensed spectrum. The scheduling cycle may include N number of time scheduling unit. The anchor carrier may occupy a first or last M number of time scheduling units of a N number of time scheduling units. The data carrier occupies a time scheduling unit other than the first or last M number of time scheduling units in the N number of time scheduling units. The first carrier is the anchor carrier or the data carrier. The base station may switch from the first carrier to a second carrier.

Abstract: This present disclosure discloses example communication methods and communications apparatuses. One example communication method includes a terminal device determining a first offset of a first power class and a second offset of the first power class when a power class of the terminal device is the first power class. A compensation amount of the first power class is determined based on the first offset and the second offset. A determination as to whether to camp on a first cell is made based on the second offset and the compensation amount of the first power class.

Abstract: A method and an apparatus for scheduling a system information block are disclosed, to increase a probability of obtaining a system information block by a terminal. A network device sends a master information block to the terminal, where the master information block includes DMTC period information; and the terminal receives the master information block, and detects a system information block, at a location of a subframe in a DMTC period. Alternatively, the master information block includes DMTC period information and DMTC time window information, and the terminal detects a system information block, at a location of a subframe in a DMTC period and in a DMTC window size. Alternatively, the master information block includes system information block period information or MF system information block content change indication information, and the terminal determines, based on the system information block period information, whether content of the detected system information block is changed.
