GRANT-FREE RESOURCE ALLOCATION METHOD, USER EQUIPMENT, AND NETWORK DEVICE
First Claim
1. A grant-free resource allocation method, comprising:
- when user equipment moves from a first cell to a second cell, obtaining, by the user equipment, an ID that is of a second grant-free resource area to which the second cell belongs and is broadcast by a second network device; and
if the ID of the second grant-free resource area is the same as a preobtained ID of a first grant-free resource area to which the first cell belongs, performing, by the user equipment UE, grant-free communication based on a first UE ID corresponding to the first cell.

Abstract
Embodiments of this application provide a grant-free resource allocation method, used by user equipment to perform grant-free communication based on a first UE ID corresponding to a first cell, without initiating a resource reconfiguration request to a second network device for resource reconfiguration. Therefore, signaling overheads and a communication latency are reduced. The method in the embodiments of this application includes: when user equipment moves from a first cell to a second cell, obtaining, by the user equipment, an ID that is of a second grant-free resource area to which the second cell belongs and is broadcast by a second network device; and if the ID of the second grant-free resource area is the same as a preobtained ID of a first grant-free resource area to which the first cell belongs, performing, by the user equipment, grant-free communication based on a first UE ID corresponding to the first cell.

7. A grant-free resource allocation method, comprising:
-
when user equipment moves from a first cell to a second cell, obtaining, by the user equipment, an identity of the second cell; and if the identity is in a cell identity list preobtained by the user equipment, performing, by the user equipment, grant-free communication based on a first UE ID corresponding to the first cell, wherein each cell in the cell identity list belongs to a same grant-free resource area;
orif the identity is not in a cell identity list preobtained by the user equipment, sending, by the user equipment, a resource reconfiguration request to a second network device, receiving configuration information that is of a third target grant-free resource and is sent by the second network device, and performing, by the user equipment, grant-free communication based on the configuration information of the third target grant-free resource. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus, comprising:
-
a non-transitory memory, configured to store instructions; a processor, configured to execute the instructions, and when executing the instructions, is configure to; when user equipment moves from a first cell to a second cell, obtain an ID that is of a second grant-free resource area to which the second cell belongs and is broadcast by a second network device; and if the ID of the second grant-free resource area is the same as a preobtained ID of a first grant-free resource area to which the first cell belongs, perform grant-free communication based on a first UE ID corresponding to the first cell. - View Dependent Claims (14, 15, 16, 17, 18)
