System and method for measuring characteristics of neighbor cells using a synthesized composite antenna pattern

摘要

A method includes receiving in a receiver transmissions from a serving cell that serves the receiver and from one or more neighbor cells. The transmissions are received via multiple receive antennas to produce multiple respective output signals. The multiple output signals are weighed with respective weights, and the weighted output signals are combined to produce a combined output signal. The weights are selected so as to form a composite antenna pattern having a first antenna gain in one or more first directions that point toward the neighbor cells, and a second antenna gain, lower than the first antenna gain, in a second direction that points toward the serving cell. Characteristics of the one or more neighbor cells are measured by processing the combined output signal in which the transmissions received from the serving cell are attenuated.

1. A method, comprising:
in a receiver, receiving transmissions from a serving cell that serves the receiver and from one or more neighbor cells, wherein the transmissions are received via multiple receive antennas to produce multiple respective output signals; weighting the multiple output signals with respective weights, and combining the weighted output signals to produce a combined output signal, wherein the weights are selected so as to form a composite antenna pattern having a first antenna gain in one or more first directions that point toward the neighbor cells, and a second antenna gain, lower than the first antenna gain, in a second direction that points toward the serving cell; measuring characteristics of the one or more neighbor cells by processing the combined output signal in which the transmissions received from the serving cell are attenuated by the composite antenna pattern.
