Wireless resource management method, base station and terminal thereof

Abstract

The invention is suitable for the communication field and provides a wireless resource management method and an apparatus. The method comprises the following steps that a receiving terminal UE sends a wireless resource control RRC signaling after completing reference signal arrival time difference RSTD measurement in one or more observation and positioning reference signal positioning measurement opportunities, wherein the RRC signaling comprises an RSTD measurement result in the one or more positioning reference signal positioning measurement opportunities; the RSTD measurement result is expressed as reference signal subframe arrival time TOA of a plurality of cells or the reference signal arrival time difference RSTD of the plurality of cells relatively to positioning reference cell arrival time; according to the reference signal subframe arrival time of the plurality of cells or the reference signal arrival time difference, wireless resource management is performed. By using a technical scheme provided in an embodiment of the invention, an advantage of reducing time delay is possessed.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to a wireless resource management method, a base station and a terminal. Background technique [0002] The location information of the terminal can be applied to radio resource management, and the auxiliary serving base station manages the radio resources used by the terminal. For example, according to the location information, estimate the distance (D) between the terminal and each neighboring base station, estimate the propagation delay (PD), estimate the path loss (PL), and uplink lead time (TA) and other parameters, which are used to assist radio resource management. The terminal is also called user equipment (UE). [0003] In the LTE (Long Term Evolution) positioning protocol LPP (LTE Positioning Protocol) defined by 3GPP (Third Generation Partnership Project), the measurement process based on OTDOA (Observed Time Difference of Arrival) is as follows: [0004] Each cell ...

AI Technical Summary

Problems solved by technology

[0010] According to D i For wireless resource management, there will be a certain delay, including the transmission delay from the UE to the serving base station, the transmission delay from the serving base station to the service terminal positioning center, the calculation and processing delay of the service terminal positioning center, and the service terminal positioning The time delay from the center to the serving base station, as well as the RRM calculation and processing delay, etc., cause a large delay in using positioning information to assist wireless resource management
