Per-cell timing and/or frequency acquisition and their use on channel estimation in wireless networks

摘要

A method, an apparatus, and a computer program product for wireless communication are provided in which a system timing is estimated, derived from timing of one or more cells, a timing offset is determined for a plurality of cells relative to the estimated system timing, and signals received form the plurality of cells are processed using the timing offsets. In addition, a method, an apparatus, and a computer program product for wireless communication are provided in which a carrier frequency is estimated, derived from a frequency of one or more cells, a frequency offset is determined for a plurality of cells relative to the estimated system timing, and signals received form the plurality of cells are processed using the frequency offsets.

1. A method of wireless communication by a user equipment (UE), comprising:
estimating a carrier frequency, wherein the estimated carrier frequency is derived from a frequency of one or more cells; determining frequency offsets, relative to the estimated carrier frequency, for a plurality of the one or more cells including at least one serving cell; and processing signals received from the plurality of cells based on one or more of the frequency offsets, the processing including
determining an average frequency offset from one or more of the determined frequency offsets; andprocessing signals received from all or a subset of the plurality of cells based on the average frequency offset.
