However, with the indicator set to TRUE, the UE still does not receive information indicating when muting occurs and for which resource block (RB) it occurs, which means that the UE still needs to blindly detect in each cell when to use PRS silence

Embodiment Construction

[0040] As a non-limiting example, figure 1 One embodiment of a wireless communication network 10 is illustrated comprising a radio access network (RAN) 12 and an associated core network (CN) 14 . RAN 12 includes a number of base stations 16, such as BSs 16-1, 16-2, and so on. Unless required for clarity, the reference numeral 16 is used to refer to BS 16 both in the singular and in the plural. Each BS 16 provides one or more "cells" 18, such as cell 18-1 for BS 16-1, cell 18-2 for BS 16-2, and so on. A cell 18 represents the radio service coverage provided by each BS 16 for supporting communication with user equipment 20, eg UE 20-1, UE 20-2, etc.

[0041] Correspondingly, the CN 14 communicatively links the UEs 20 to each other and / or links the UEs 20 to communication devices in other networks such as the Internet, PSTN, and the like. To this end, CN 14 includes a number of nodes or other functional entities. As a simplified example, the illustrated CN 14 is depicted as ...

Abstract

In one aspect, the present invention provides a simple method of signaling reference signal muting information to a receiving radio device (50), such as a user equipment (UE) item (20). The reference signal may be, for example, a positioning reference signal and / or a cell-specific reference signal. In one or more embodiments, the present invention proposes a general solution whereby the receiving radio (50) is notified not only as to whether muting is commonly used in a cell, but also as to the specific timing and format of such muting. Furthermore, the considered method supports the use of dynamic muting patterns and thus avoids the need for statically defined muting patterns, as well as providing coordinated muting control across two or more network cells. In at least one embodiment, the static or less dynamic aspects of the muting configuration are signaled via higher layer signaling, while the more dynamic aspects of the muting configuration are signaled using lower layer signaling.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 314,724, filed March 17, 2010, and U.S. Nonprovisional Patent Application No. 12 / 858,809, filed Aug. 18, 2010, hereby incorporated by reference Both applications are incorporated in their entirety. technical field [0003] The present invention relates generally to interference management in a wireless communication network, and in particular to controlling the muting of reference signals transmitted by one or more base stations in the network and signaling related muting configuration information. Background technique [0004] Wireless communication networks use reference signal transmission to support several key functions. In this regard, the "reference" signal provides the receiving radio with some type of reference information—timing, frequency, phase, etc.—that enables the receiving device to make certain measurements. For example, cell-specific referen...
