Abstract: In one exemplary embodiment, a method includes: obtaining feedback from at least one mobile terminal in a communication system; determining, based on the obtained feedback, whether at least one of a downlink shared channel transmit power and a transmission pattern should be modified, wherein the downlink shared channel is used to communicate with a plurality of users; and in response to determining that at least one of the downlink shared channel transmit power and the transmission pattern should be modified, modifying at least one of the downlink shared channel transmit power and the transmission pattern. In a further exemplary embodiment, the method further includes: transmitting a communication to the plurality of users via the downlink shared channel, wherein the communication is a multimedia broadcast/multicast service transmission and the downlink shared channel is a high speed downlink shared channel or a physical downlink shared channel.

Abstract: A method of adjusting downlink transmission power at a base station based on the measured SIR relative to a referenced level in a mobile terminal. The referenced level can be the targeted SIR or zero. When the measured SIR is greater than the referenced level, the measured SIR is further compared to a first threshold value in order to determine the step size for power reduction. When the measured SIR is smaller than the referenced level, the measured SIR is further compared to a second threshold value in order to determine the step size for power increase. The first and second threshold values can be derived from the target SIR and TPC step size as provided in the RRC signal. Furthermore, the step values and threshold can be based on statistical analysis while the system is running.

Abstract: A method, device and system, for determining downlink transmission power step size for both UP and DOWN transmission power control commands (TPC). The method, device and system use reception quality and a plurality of thresholds to determine these step sizes. Provision is made for determining step size and the TPC command values when the TPC command is evaluated to be erroneous and when reception quality is less than a minimum threshold value.
