Resource allocation in a communication system

摘要

Methods and corresponding systems for determining a transmit power in a mobile device include receiving, in the mobile device, a cell-wide power control parameter related to a target receive power at a serving base station. Thereafter, a transmit power is calculated in response to the cell-wide power control parameter and an implicit mobile-specific power control parameter. The mobile device then transmits using the transmit power. The cell-wide power control parameter can be a cell target signal to interference-plus-noise ratio, or a fractional power control exponent. The implicit mobile-specific power control parameter can be a modulation and coding level previously used by the mobile device, or a downlink SINR level measured by the mobile device.

1. A method for controlling power transmitted by a mobile device comprising:
at the mobile device: sending a resource allocation request from the mobile device to a base station, wherein, when a resource utilization limitation of the mobile device exceeds a reporting threshold, the resource allocation request comprises a maximum number of resource blocks based on one or more of a current power level and a current modulation and coding scheme (MCS); after sending the resource allocation request, receiving a dynamic resource allocation grant from the base station, wherein the dynamic resource allocation grant includes a power control instruction for use during the duration of the dynamic resource allocation grant; wherein the receiving the dynamic resource allocation grant comprises receiving a dynamic resource allocation grant that includes an allocation of a number of resource blocks associated with an allocation bandwidth, and the power control instruction comprises an instruction to use a dynamic grant transmit power; and when the allocated number of resource blocks exceeds the maximum number of resource blocks, automatically reducing a transmit power.
