<p>Techniques for controlling transmit power are described. Due to link imbalance, a downlink (DL) serving cell may have the best downlink for a UE, and an uplink (UL) serving cell may have the best uplink for the UE. In one design of UL power control, the UE receives first and second UL TPC commands from the DL and UL serving cells, respectively, and adjusts its transmit power based on these UL TPC commands and in accordance with an OR-of-the-UPs rule. In one design of DL power control, the UE generates a DL TPC command based on received signal qualities of both the DL and UL serving cells. In another design, power control is performed independently for the DL and UL serving cells. The UE generates a separate DL TPC command for each cell, which adjusts its transmit power based on the DL TPC command for that cell.</p> |
