SYSTEMS AND METHODS TO SUPPORT MULTIPLE CONFIGURATIONS FOR POSITIONING REFERENCE SIGNALS IN A WIRELESS NETWORK
First Claim
1. A method for supporting multiple configurations of reference signals for Observed Time Difference of Arrival (OTDOA) positioning, comprising:
- sending, by a user equipment to a location server, a message indicating reference signal characteristics supported by the user equipment, wherein the reference signal characteristics include a user equipment supported reference signal bandwidth;
receiving, at the user equipment from the location server, positioning assistance data including reference signal configuration parameters for each cell of a plurality of cells transmitting reference signals according to the user equipment supported reference signal bandwidth; and
performing, by the user equipment, positioning measurements for one or more of the plurality of cells transmitting the reference signals based on the reference signal configuration parameters for each cell of the plurality of cells.

Abstract
Disclosed are techniques for supporting multiple configurations of reference signals for OTDOA positioning in a wireless network. In an aspect, a UE sends to a location server, a message indicating reference signal characteristics supported by the UE, where the reference signal characteristics include a UE supported reference signal bandwidth. The UE then receives from the location server, positioning assistance data including reference signal configuration parameters for each cell of a plurality of cells transmitting reference signals according to the UE supported reference signal bandwidth. The UE may then perform positioning measurements for one or more of the plurality of cells transmitting the reference signals based on the reference signal configuration parameters for each cell of the plurality of cells.
