A power control method and a base station are provided. The base station obtains a first resource block (RB) set and a second RB set after a power control cycle arrives, wherein the first RB set is an RB set that is allocated by the first base station to first user equipment (UE) in a first cell at each transmission time interval (TTI) in the power control cycle, and the second RB set is an RB set that is allocated by a second base station to second UE in a second cell at each TTI in the power control cycle. Then the base station performs power control on the first UE based on the first RB set and the second RB set.

An apparatus for controlling an Uplink (UL) power in a wireless communication system including a transmitter/receiver and a controller may be provided. The transmitter/receiver may receive/decode Downlink (DL) data, transmit a feedback signal with respect to the DL data, and receive Transmit power Control (TPC) commands from active set cells including a serving cell. The controller may decode the TPC commands to generate a combined TPC command, in which decoded TPC commands of the active set cells are combined, and calculate a transmission error rate of an UL feedback transmission signal and a requested rate of transmit power increase of the serving cell, determine a transmit power gain offset and the requested rate of transmit power increase, determine an UL power for transmitting a feedback signal with respect to the received DL data based on the transmit power gain offset, and transmit the feedback signal based on the UL power.

Systems and methods are described for reducing processing time of messages that are repeatedly received, with increasing frequency, by a device (e.g., user equipment, base station etc.). For example, the systems and methods would have a mobile device increase power, possibly to maximum power-out, per policy, if messages beyond the original are received and the time between those messages is decreasing. The decrease in time between messages indicates a more urgent need for the mobile device to power up. The systems and methods can be adapted for different types of messages (e.g., power-up, power-down, resource request, bandwidth request, service type, call type origination, quality-of-service request, application type, etc.). Each message type is associated with a policy (pre-determined or adaptive) that indicates the default behavior when the method detects a decrease in time between messages.
