Abstract: A terminal coverage method and an apparatus is provided. The method includes, obtaining, by a network device, position information of a terminal in a cell relative to the network device, then the network device divides the cell into a plurality of areas based on the position information of the terminal in the cell relative to the network device, and sends information to terminals in different areas of the plurality of areas at different time points, where the information is carried on a channel with a maximum repetition count less than a threshold. In other words, the network device divides the cell into the plurality of areas, and sends the information carried on a channel with a limited repetition count to a terminal in at least one target area in the plurality of areas in a time division manner.

Abstract: A control information processing method, a base station, and a terminal are provided. A base station determines jointly encoded control information for an uplink subframe, where the jointly encoded control information is control information obtained by jointly encoding first control information and second control information; and the base station sends the jointly encoded control information. A terminal receives jointly encoded control information sent by a base station, where the jointly encoded control information is for an uplink subframe, and is control information obtained by jointly encoding first control information and second control information; and the terminal performs clear channel assessment CCA based on the jointly encoded control information, and occupies, after finishing the CCA, the uplink subframe to send a signal. According to the present invention, control signaling overheads can be reduced.

Abstract: Embodiments of this application provide a random access method, a communications apparatus, a chip, and a storage medium. A network device sends a first synchronization signal/PBCH block SSB on a first candidate SSB occasion, and/or sends a second SSB on a second candidate SSB occasion, where both the first candidate SSB occasion and the second candidate SSB occasion are associated with a first random access channel time-frequency-code resource. The network device receives random access information sent by a terminal device on the first random access channel time-frequency-code resource. According to the embodiments of this application, two candidate SSB occasions are mapped to a same PRACH time-frequency-code resource. In this way, even if an SSB cannot be sent on one of the two candidate SSB occasions due to a channel sensing failure, but another SSB can be sent on the other candidate SSB occasion due to a channel sensing success.
