[0004] However, the channels that carry these feedback information are not clear at present. If the shared channel is used to carry these feedback information, since the shared channel can also be used to carry other information, it is difficult for the network device to know whether to receive the above feedback information, resulting in the above feedback information. inaccurate reception

Abstract

Provided are sidelink information sending and receiving methods and devices, the sending method comprising: sending target information, and the target information being used for determining feedback information for a sidelink SL. Since terminal equipment can send the target information for determining the feedback information for the sidelink SL, network equipment can accurately receive the feedback information of the sidelink, thereby improving communication effectiveness.

Description

technical field [0001] The present invention relates to the technical field of communications, and more particularly to a method and device for sending and receiving secondary link information. Background technique [0002] A secondary link (Sidelink, SL), also called a side link or a side link, is used for direct data transmission between terminal equipment (User Equipment, UE) without going through a network equipment. SL data transmission methods include broadcast, multicast and unicast. Both broadcast and multicast are one-to-many (one to many) transmission methods, but the concept of UEs belonging to the same UE group does not exist in the broadcast transmission method, and unicast is a one-to-one (one to one) transmission method. ) transmission method. [0003] At present, for the two transmission methods of multicast and unicast, the receiver can send feedback information to the sender to explain the reception of the SL data object. For example, the receiver can fee...
