Abstract: A base station determines a muting configuration for reference signal (RS) transmission as a pattern defined by the combination of a muting sequence and a reference point. Muting occasions for a given wireless communication network cell may be differentiated from another cell by use of a different muting sequence, a different reference point, or both. Wireless communication apparatuses such as User Equipments (UEs) determine when the reference signals are muted in the cell based on the periodic muting sequence and the reference point received in assistance data transmitted by the base station. The network may alternatively utilize a common muting sequence with different reference points, a common reference point with different muting sequences, or different sequences and different reference points across multiple cells.

Abstract: In one aspect of the invention presented herein, a mobile terminal requests positioning assistance data from its supporting wireless communication network, in response to receiving a positioning request from a positioning node. Further, in response to receiving the positioning assistance data from the network, the mobile terminal sends the positioning assistance data to the positioning node. In this manner, the positioning node advantageously gains access to network-generated positioning assistance data without need for requesting it from the network. In at least one embodiment, the mobile terminal receives the positioning request from the positioning node over a User Plane (UP) connection. However, the mobile terminal sends the positioning assistance data request to the base station over a Control Plane (CP) connection, and receives the requested positioning assistance data via the CP. The terminal transfers that data to the UP and sends it to the positioning node.
