Abstract: A method includes determining, by a network side device, N fixed channels. The method further includes determining, by the network side device, a first fixed channel from the N fixed channels, sending, by the network side device, a discovery reference signal on the first fixed channel, and performing data transmission on a data channel through frequency hopping. The data channel includes a channel other than the N fixed channels. N is an integer greater than or equal to 2.

Abstract: Embodiments of this application provide an anchor channel transmission method and apparatus, and a communications apparatus. According to the method, an anchor channel occupies a lowest frequency or a highest frequency of a system bandwidth, and power boosting is performed on at least the anchor channel. According to technical solutions provided in the embodiments of this application, the anchor channel may occupy the lowest frequency or the highest frequency of the system bandwidth, other anchor channels are adjacent to the anchor channel, and anchor channels in the other anchor channels are adjacent to each other, so that when power boosting is performed on one or more anchor channels, a smallest quantity of RBs lose powers.

Abstract: A message transmission method and apparatus are provided. The method includes: determining, by a base station in a first sending cycle, a first time unit for sending a first message, where the first sending cycle includes one of the following cycles: a paging cycle or a broadcast cycle, the first message includes one of the following messages: a paging message or a broadcast message, and the first time unit includes one of the following time units: one or more subframes, or one or more slots. When determining, before a start location of the first time unit, that a CCA fails, determining a second time unit(s) for sending the first message; and sending the first message to a terminal device in one or more second time units for sending the first message that are after the first time unit for sending the first message.
