Abstract: A first terminal obtains a first transmission resource that is sent by an access network device and that is used by the first terminal to send data on a sidelink, where the sidelink is a wireless communication link between the first terminal and a second terminal, and the first transmission resource is a resource of an unlicensed spectrum. The first terminal performs a channel access procedure on the unlicensed spectrum. The first terminal sends first information to the access network device when the first terminal determines that a failure occurs in the channel access procedure performed on the unlicensed spectrum, where the first information is used to request to allocate a second transmission resource to the sidelink of the unlicensed spectrum.

Abstract: A communications method and apparatus. The communications method includes: transmitting a first request to a network device through a first resource, where the first request is used to request beam failure recovery of a first cell or is used to request system information of the first cell, the first resource is a resource of a second cell, and the first cell and the second cell are serving cells of a same terminal; and receiving a first response corresponding to the first request from the network device. Therefore, when a terminal has a plurality of serving cells, the terminal may transmit a request across cells (or across carriers), to improve transmission reliability.

Abstract: Embodiments of this application provide a random access processing method. A random access preamble and uplink data are sent in an initiation phase of a random access procedure, and the random access procedure is ended in time after feedback information for the uplink data is received. According to technical solutions provided in the embodiments of this application, a terminal side device may send the uplink data when sending the random access preamble in the random access procedure. In addition, the random access procedure can be ended in advance after the feedback information for the uplink data is received.
