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 capabilities message identifying two or more reference signal bandiwth supported by the uer equipment to enable the location server to select a plurality of cells transmitting reference signals according to the two or more reference signal bandwidths supported by the user equipment, wherein the two or more reference signal bandwidths include at least one wide reference signal bandwidth and at least one narrow reference signal bandwidth;
receiving, at the user equipment from the location server, positioning assistane data including reference signal configuration parameters for each cell of the selected plurality of cells transmitting reference signals according to the two or more reference signal bandwidths supported by the user equipment; and
performing, by the user equipment, positioning mesurements for one or more of the selected plurality of cells transmitting the reference signals based on the reference signal configuration parameters for each cell of the one or more of the selected 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.
