Patent ID: 8600398

Claim:
A method for defining positioning configuration in a wireless network, the method comprising: determining, by a first network node, muting patterns of one or more cells of the wireless network; and providing assistance information from a second network node to the UE, wherein some or all cells of the network are capable of wirelessly transmitting positioning reference signals (PRS) during positioning occasions, the PRS transmissions being usable to determine a location of a user equipment (UE), each positioning occasion being composed of a predetermined number N PRS consecutive subframes having a predetermined periodicity of N subframes, N>N PRS , such that the N PRS positioning subframes repeat every N subframes, both N and N PRS being integers greater than zero, wherein the muting pattern of a cell indicates a plurality of positioning occasions in which the cell will transmit its PRS and a plurality of positioning occasions in which the cell will mute its transmission of the PRS, wherein a number of muted positioning occasions is greater than zero, and wherein the assistance information includes the muting pattern of at least one cell determined by the first network node.
