SYSTEM, TRANSMITTER, RECEIVER AND METHOD FOR COMMUNICATION POWER CONTROL

摘要

A system, transmitter, receiver and method for communication power control by the transmitting entity (150A) keeping a sequence number counter (200) per UE (130A) that is incremented whenever a common channel transmission is made specifically to that UE. The value of the counter is signalled inside the message itself (or possibly by other signalling means) across the Uu interface. When the intended recipient UE correctly decodes a message, it also decodes the counter value. It compares this counter value with the last correctly received sequence number, which it holds in a memory (300), and deduces whether there are any missing sequence numbers, and accordingly effects transmission power control
