Measuring method, positioning server and user equipment

Abstract

The embodiment of the invention provides a measuring method, a positioning server and user equipment. The method comprises the following steps that: the positioning server obtains respective TA values of at least two service cells determined for the user equipment by a macro base station and at least one micro base station; the positioning server selects the service cell corresponding to the minimal TA value in the TA values as a reference cell; the positioning server generates first exceptedRSTD according to the position information of the base station of the reference cell and the position information of the base station to which a non-reference cell capable of serving the user equipment belongs, and generates a first expectedRSTD-Uncertainty according to the selected TA value; and the positioning server sends positioning auxiliary data message to the user equipment, wherein the positioning auxiliary data message comprises the first exceptedRSTD and the first expectedRSTD-Uncertainty to enable the user equipment to measure the RSTD of the non-reference cell according to the first exceptedRSTD and the first expectedRSTD-Uncertainty. The embodiment of the invention enables the user equipment to measure the RSTD of the non-reference cell, and the method is simple and liable to realize, so that the measuring efficiency is effectively improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a measurement method, a positioning server and user equipment. Background technique [0002] In a heterogeneous scenario of a wireless communication system with carrier aggregation (Carrier Aggregation, CA for short), the user equipment can connect multiple serving cells currently serving the user equipment with multiple base stations (that is, base stations operating on different carriers, Such as a macro base station and at least one micro base station), that is, the user equipment can send an uplink signal to the macro base station or micro base station to which each serving cell belongs through each serving cell, and can also transmit an uplink signal from each serving cell through each serving cell The macro base station or the micro base station to which the cell belongs receives the downlink signal. In order to ensure that the uplink signal sent by the user equipment through ea...
