Problems solved by technology

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 . The 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 BSs 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, such as UE 20-1, UE 20-2, and so on.

[0041] Correspondingly, the CN 14 communicatively links the UEs 20 to each other and / or to communication devices in other networks, such as the Internet, PSTN, or 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 i...

Abstract

In one aspect, the present invention provides a simple method of signaling reference signal muting information to receiving radio equipment (50), such as items of user equipment (UEs) (20). The reference signals may be positioning reference signals and / or cell-specific reference signals, for example. In one or more embodiments, the present invention proposes a general solution whereby the receiving radio equipment (50) is informed not only on whether muting is used in general in a cell, but also the particular timing and formatting of such muting. Further, the contemplated method provides for the use of dynamic muting patterns, and thus avoids the need for statically defined muting patterns, and provides for coordinated muting control, across two or more network cells. In at least one embodiment, static or less dynamic aspects of the muting configuration is signaled via higher-layer signaling, while lower-layer signaling is used to signal more dynamic aspects of the muting configuration.

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...
