Abstract: Embodiments of the present invention provide a communications method, a communications system, an access network device, a terminal, and a core network device. For all UEs accessing the access network device, before relay node selection is performed, it is determined which UEs are capable of serving as candidate relay nodes, so as to perform a relay node selection operation only on the UEs that are capable of serving as candidate relay nodes when performing the relay node selection, thereby saving operation overhead, reducing time and resources overhead during the relay node selection, and improving transmission efficiency.

Abstract: Embodiments of this application provide a beam configuration method and apparatus. The method includes: determining base station scheduling information rank, and determining a direction of arrival power spectrum; determining peak information based on the direction of arrival power spectrum; determining, based on the peak information, beam directions that meet power conditions; selecting, based on a preset filtering condition, at least one candidate beam direction from the beam directions that meet the power conditions; and determining a target beam direction of a terminal from the at least one candidate beam direction based on the base station scheduling information rank, a value of a channel quality indicator CQI, and the direction of arrival power spectrum. In this way, a beam configuration manner on a terminal side is more flexible, to meet requirements of different service scenarios, and improve stability of a communications link.

Abstract: A cell search method and a communications apparatus are provided. The method includes the following: before searching for a cell, a terminal device may determine, with reference to historical access information of another terminal device, whether there is a cell at the location, and adjust, based on a determining result, a value of a search parameter used to search for a cell. For example, if there is a cell, the terminal device may adjust the search parameter to accelerate a search. If there is no cell, the terminal device may perform no search, or adjust the search parameter to reduce an unnecessary cell search performed by the terminal device, so that power consumption of the terminal device can be reduced.

Abstract: A method for sending a wake-up frame includes generating, by a sending device, a plurality of short wake-up frames, where each of the plurality of short wake-up frames includes an index and an address segment. The index is used to indicate a number of the address segment, the plurality of short wake-up frames include at least N short wake-up frames whose indexes are different from each other, N is a positive integer, and N≥2. The method further includes sending, by the wake-up device, the plurality of short wake-up frames so that a receiving device can determine, based on N address segments carried in any N short wake-up frames whose indexes are different from each other in the plurality of short wake-up frames, whether the receiving device is a target wake-up device of the sending device.
