Title:
UPLINK SIGNAL LOCATION METHOD, COMMUNICATION BASE STATION, MEASUREMENT BASE STATION, AND UE
Document Type and Number:
WIPO Patent Application WO/2022/017369
Kind Code:
A1
Abstract:
Disclosed in the present application are an uplink signal location method, a communication base station, a measurement base station, and a UE, comprising: the communication base station determines that the UE satisfies the condition of releasing an RRC connection, the UE has a location requirement, and an LMF entity indicates the UE to use the uplink signal location method; transmit an RRC connection release message to the UE, wherein the RRC connection release message comprises an SRS resource that is configured for the UE and used for location under an idle state or an inactive state; the UE receives the RRC connection release message, releases the RRC connection and enters the idle or inactive state, and uses the SRS resource to transmit an SRS. By using the method provided by the present application, under the idle state or the inactive state, a terminal continues to transmit the SRS used for location so as to satisfy the measurement requirement of uplink location, thereby being capable of saving power, ensuring that a network performs timely and effective location measurement and calculation, and improving location accuracy.
