摘要： This application provides a relay communications method and apparatus. A first terminal device receives, from a second terminal device, indication information used to indicate the second terminal device to stop providing a relay service between the first terminal device and a radio access network device. The first terminal device sends notification information to the radio access network device through a third terminal device, to notify the radio access network device that the first terminal device accesses the radio access network device by using a relay service of the third terminal device. In this way, the radio access network device may communicate with the first terminal device through the third terminal device.

摘要： The present disclosure relates to terminal devices, access network devices, air interface configuration methods, and wireless communications systems. In one example method, a second access network device in a radio access network determines air interface configuration information of an air interface between a terminal device and the radio access network, and sends a first air interface configuration message comprising the air interface configuration information to a first access network device in the radio access network. The first access network device and the second access network device use different wireless communications standards.

摘要： Embodiments provide a network access method and a device. In accordance with the method, a preamble sequence may be received by a second network device from a terminal device on a time-frequency resource occupied by the preamble sequence. A transmit beam may be determined for sending an access response message to the terminal device. The access response message can be sent to the terminal device using the transmit beam. The second access device can send the access response message to the terminal device through beamforming, so that a coverage area of the second access device can be enlarged, directivity of data sent to the terminal device can be improved, and a probability that the terminal device receives the access response message is improved. Therefore, a rate that the terminal device succeeds in accessing the second access device is improved.

摘要： Embodiments of the present application relate to the communications field, and provide example random access methods, apparatus, and systems, so that a terminal can access a beam in time. An example solution includes receiving, by a terminal, a plurality of signals sent by a first access device on a plurality of beams. A beam of a strongest signal in the plurality of beams is determined and a preamble signal for the beam of the strongest signal is generated. The preamble signal of the beam of the strongest signal is sent to the first access device, so that the first access device identifies, based on the received preamble signal, the beam selected by the terminal to access.

摘要： The present application discloses a wireless local area network access point search method, an apparatus, and a system, relates to the field of communications technologies, and can reduce power consumption for passive scanning. According to the method, beacon sending information of a wireless local area network access point and measurement information of a user equipment are matched, so that the user equipment can search for the wireless local area network access point only at the time when and a frequency channel number at which the wireless local area network access point sends a beacon. Compared with the prior art in which a user equipment needs to continuously keep a state of searching for a wireless local area network access point, the present application greatly shortens time spent by the user equipment in listening to a beacon, and therefore reduces power consumption of passive scanning.

摘要： A communication method and apparatus, and a system. A first terminal device obtains first information, where the first information includes a first multicast and broadcast service MBS service identifier and first sidelink SL resource information. A mapping relationship exists between the first MBS service identifier and the first SL resource information. A first MBS is an MBS supported by a first relay terminal device, and the first SL resource information is usable for transmitting data of the first MB S to the first terminal device. The first terminal device receives, based on the first SL resource information, the data that is of the first MBS and that is sent by the first relay terminal device. The first terminal device transmits MBS data in a scenario in which a relay terminal device supports an MBS service.
