Method and arrangement for interference congestion control

摘要

In a method of uplink interference congestion control in an interference suppression capable receiving node associated with a plurality of users in a wireless communication system, applying interference suppression to received signals in the node, to provide interference suppressed received signals. Subsequently, estimating a rise over thermal value for the uplink, based on the interference suppressed received signals, and determining a load measure for the uplink based on the estimated rise over thermal value. Finally, controlling interference congestion on the uplink based on the determined load measure.

1. A method of uplink interference congestion control in an interference suppression capable receiving node associated with a plurality of users of an uplink in a wireless communication system, the method comprising:
applying interference suppression to each of a plurality of received user signals in said node, to suppress other-user, same-band, interference to each received user signal, thereby providing interference suppressed received signals; estimating a rise over thermal value for said uplink, based on said interference suppressed received signals and an estimate of thermal noise; determining a load measure for the uplink based on said estimated rise over thermal value; and controlling interference congestion on said uplink based on said determined load measure.
