摘要： Embodiments of the present invention disclose a link re-establishment method and a device, and relate to the communications field, to resolve a problem that communication is interrupted in a process of communication between a base station and UE because data cannot continue to be transmitted due to a block. A specific solution is as follows: When detecting that a first downlink beam pair set is invalid, UE sends a first uplink signal to a base station at a moment n by using a first uplink beam pair set through a first uplink channel, where the first uplink signal is used to notify the base station that the first downlink beam pair set is invalid; and the UE detects, at a moment n+k, a first downlink signal sent by the base station by using a second downlink beam pair set through a first downlink channel, to obtain a first detection result, where the first downlink signal is used to acknowledge that the base station receives the first uplink signal. The embodiments of the present invention are applied to a link re-establishment process.

摘要： This application provides a communication method and apparatus. The method includes: A first device receives a control channel and a first data channel, where the first device receives the control channel and the first data channel based on a same spatial domain receive parameter, or the first device receives both the control channel and the first data channel through an omnidirectional beam, and indication information of a spatial domain receive parameter of a second data channel is carried on the control channel and/or the first data channel. The first device receives the second data channel based on the indication information. In this application, the first device may first determine the spatial domain receive parameter of the second data channel based on the indication information of the spatial domain receive parameter of the second data channel in the control channel or the first data channel. Therefore, when the second data channel is being received, the determined spatial domain receive parameter may be used, thereby improving receiving performance of the data channel.

摘要： Embodiments of this application provide a resource selection method and apparatus, and relate to the communication field, to reduce a collision between reserved resources of terminal devices and subsequent resource reselection, thereby improving communication efficiency. The method includes: A first terminal device determines an initial candidate resource set including M resources, and determines, based on an RSRP and a collision index that are associated with SCI received in a sensing window, whether to exclude an i th resource in the M resources from the initial candidate resource set, to obtain a candidate available resource set. The collision index is an index of a collision between a reserved resource indicated by the SCI received in the sensing window and an i th periodic resource. The i th periodic resource includes the i th resource and a resource obtained after the i th resource is extended based on a preset first period. Herein, M is a positive integer, and i is a positive integer from 1 to M.

摘要： This application provides a resource selection method and apparatus. The method includes: A first terminal device receives first indication information from a second terminal device, where the first indication information indicates quality of SL transmission between the first terminal device and the second terminal device on a first resource, and the first resource is a resource indicated by a third terminal device (S310); and the first terminal device determines that a quantity of times the first indication information meets a preset condition is greater than or equal to a preset value, and selects a second resource, where the second resource is different from the first resource (S320). According to the technical solution of this application, the preset condition is set, and resource selection is performed when link interference is large, to help improve an anti-interference capability of a communication system; and when the first resource indicated by the third terminal device can meet the quality of the SL transmission between the first terminal device and the second terminal device, there is no need to perform resource selection, which reduces energy consumption overheads.
