Patent ID: 8594690

Claim:
A method, in a wireless terminal served by a serving cell in a wireless communication system utilizing coordinated multipoint transmission from two or more subcells in each of a plurality of cells, of reporting downlink signal measurement information, the method comprising: monitoring, in the wireless terminal, signal quality metrics for a first set of downlink signals comprising a first common channel signal transmitted utilizing the coordinated multipoint transmission from two or more subcells of a neighbor cell; evaluating the monitored signal quality metrics in the wireless terminal; selectively increasing, in the wireless terminal, at least one of a measurement rate and an event evaluation rate for at least a first subcell-specific signal from the neighbor cell, based on said evaluating; and reporting signal quality data based on the first subcell-specific signal from the wireless terminal to a serving base station wherein selectively increasing at least one of the measurement rate and the event evaluation rate comprises increasing the measurement rate for the first subcell-specific signal from a first rate to a second rate, wherein the first rate is greater than zero.
