Title:
FAST UPLINK RESOURCE REQUEST BASED ON EXTERNAL ASSISTANCE
Document Type and Number:
WIPO Patent Application WO/2021/109013
Kind Code:
A1
Abstract:
Disclosed are techniques for wireless communication. In an aspect, a first UE receives, from a second UE over a sidelink connection between the first UE and the second UE, a request for the first UE to send, on behalf of the second UE, a request for an uplink resource configuration to a base station serving the second UE. The first UE transmits the request for the uplink resource configuration to the base station, and receives, from the base station, the uplink resource configuration for the second UE. The first UE then transmits, over the sidelink connection, the uplink resource configuration to the second UE. The second UE can then transmit, to the base station, uplink data using the uplink resource configuration.
