Wireless Terminal Measurement Configuration for CoMP Interference

The patent segments the downlink signal into multiple components: cell-specific reference signals from the base station, channel state information reference signals from the RRH, and data signals. By separating the measurement of these different signal components and applying different processing methods to each, the system can accurately measure downlink received power even when base station and RRH use the same frequencies for coordinated communication.

The patent implements a universal measurement framework where a single measurement configuration structure can handle multiple measurement targets (base station cell-specific reference signals and RRH channel state information reference signals) with different properties. The terminal device is designed to universally process different reference signal types through a unified measurement and reporting mechanism, reducing the need for separate specialized measurement procedures for each target.

The patent implements feedback mechanisms where terminals measure downlink reference signals from both base stations and RRHs, report channel quality indicators back to the network, and the network uses this feedback to dynamically adjust resource allocation, power control, and scheduling decisions. This closed-loop feedback system enables coordinated communication to achieve improved throughput while automatically managing interference through measured and reported channel conditions.
