Method and apparatus for selecting reference signal tones for decoding a channel

摘要

Methods and apparatuses are provided that include selecting reference signal (RS) or other tones to utilize in estimating a channel for decoding one or more channels. Where the RS tones are interfered by other base stations, interference cancelation can be performed over the RS tones. Since interference can vary over the tones, interference cancelation can yield RS tones of varying quality. Thus, a quality of each of the RS tones can be determined, and at least a subset of the RS tones can be selected for estimating a channel. Additionally or alternatively, the RS tones can be weighted or otherwise classified for performing channel estimation using the RS tones.

1. A method for muting tones at a first base station to aid in decoding channels of a second base station in a subframe, comprising:
determining a location of one or more tones over which the second base station transmits a reference signal, the location of the one or more tones corresponding to a subset of subframes over which the first base station transmits a broadcast channel; and muting a subset of tones of a broadcast channel transmission, at the first base station, corresponding to the location of the one or more tones in the subset of subframes.
