Title: GRANT-FREE RESOURCE ALLOCATION METHOD, USER EQUIPMENT AND NETWORK DEVICE
Abstract:
Disclosed is a grant-free resource allocation method, used for a user equipment to carry out grant-free communication according to a first UE ID corresponding to a first cell, without re-sending a resource reconfiguration request to a second network device again so as to reconfigure a resource, thereby saving on the overhead of a signalling resource and reducing the delay in communication. The method in the embodiments of the present application comprises: when a user equipment moves from a first cell to a second cell, the user equipment acquiring the ID, broadcast by a second network device, of a second grant-free resource region having the second cell; and if the ID of the second grant-free resource region is the same as the pre-acquired ID of a first grant-free resource region having the first cell, the user equipment carrying out grant-free communication according to a first UE ID corresponding to the first cell.
