Abstract: A direct link scheduling method implemented by an access point (AP) includes: multicasting or broadcasting information about multiple direct links participating in a next direct link scheduled period; obtaining, in the direct link scheduled period, sounding results sent by the both terminal devices on each of the multiple direct links, and separately allocating channel resources to the multiple direct links according to the sounding results in the direct link scheduled period; and/or sub-channels or transmission time in channel resources of two direct links interfering with each other are or is different; and sending information about the allocated channel resource to the both terminal devices on each of the multiple direct links. The embodiments of the present invention can avoid channel contention between different direct links and reduce a probability that a conflict occurs because of the channel contention.

Abstract: A data retransmission method is provided herein. The method includes sending a data frame to an electronic device and receiving an acknowledgement frame from the electronic device within a transmission opportunity duration, where the acknowledgement frame includes first acknowledgement information; and when the first acknowledgement information indicates that at least a part of data in the data frame needs to be retransmitted and further indicates a retransmission period required to complete the retransmission, retransmitting information related to the at least the part of the data to the electronic device in the retransmission period.

Abstract: A method to reduce a probability of occurrence of a hidden node in a data transmission process in a high-frequency system is disclosed. The method implemented by a communications apparatus includes determining at least one beam to be used for sending a resource reservation message, where the at least one beam includes a first beam, where a direction of the first beam is opposite to a direction of a second beam, and where the direction of the second beam is a potential transmission direction in which the communications apparatus sends information. The method further includes sending the resource reservation message by using the at least one beam, where the resource reservation message includes a resource reservation request message or a resource reservation response message, where the resource reservation request message is used to request to reserve a transmission resource, and where the resource reservation response message is used to determine to reserve a transmission resource.

Abstract: The present disclosure includes example signal sending and receiving methods and related example devices. One example method includes sending, by a first device, a notification signal to a second device on a target transmission resource, where the target transmission resource includes a third transmission resource determined according to a first transmission resource or a fourth transmission resource determined according to a second transmission resource. The first transmission resource is a resource which the first device uses to send first status information of the first device, and the second transmission resource is a resource which is used by the second device to send second status information of the second device.
