Abstract

The invention discloses a sidelink SL resource allocation method, a sidelink SL resource acquisition method, network equipment and a terminal. The network equipment is a first node or a second node ina dual-connection DC mode; the method comprises: receiving auxiliary information for allocating the special resources of the sidelink SL; and according to the auxiliary information, obtaining SL dedicated resources under the first radio access technology RAT and / or the second RAT. The network equipment provided by the invention can allocate SL special resources to the terminals under different RATs, and ensures that the terminals of different RATs realize SL transmission.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a sidelink SL resource allocation method, acquisition method, network equipment and terminal. Background technique [0002] In a mobile communication system, a sidelink (sidelink, SL), or referred to as a secondary link, a side link, or a side link, is used for direct transmission between terminals without passing through a network device. Currently, SL transmission supports two resource allocation modes, one is the scheduled resource allocation (Scheduled resource allocation) mode, in which the terminal reports a buffer state report (Buffer State Report, BSR) to the network device to provide multimedia access control ( Medium Access Control (MAC) entity corresponds to the SL buffer waiting for transmission of SL data information, and the network device controls and allocates SL transmission resources for each terminal according to the received BSR; the other is th...
