Title:

POSITIONING METHOD AND APPARATUS FOR DIFFERENT UPLINK AND DOWNLINK TDD CONFIGURATIONS

Document Type and Number:

WIPO Patent Application WO/2016/086415

Kind Code:

A1

Abstract:

Disclosed are a positioning method and apparatus for different uplink and downlink TDD configurations. When a primary cell (PCell) and a serving cell (SCell) of a user equipment (UE) have different uplink and downlink configurations at the same subframe position and the UE does not support simultaneous transmission and reception, the method comprises: a first device receives positioning information of the UE, the positioning information comprising auxiliary positioning information or auxiliary positioning information and a UE identifier, and the auxiliary positioning information comprising at least positioning reference signal (PRS) information or PRS information and a Cell ID; and if the first device determines, according to the positioning information, that the UE performs PRS measurement at the same subframe position of the SCell, the first device avoids data scheduling or sounding signal configuration at the same subframe position of the PCell and the SCell having different configurations, to enable the UE to perform PRS positioning measurement, thereby improving positioning precision.
