Abstract
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.
Claims18
A method for performing wireless communication power control in a base station, the method comprising:
- receiving a first resource allocation request from a wireless device, the first resource allocation request being responsive to a resource utilization limitation exceeding a reporting threshold for the wireless device;
- and
- sending a dynamic resource allocation grant having a first time duration associated therewith, the grant comprising a first power control instruction configured to be used by the wireless device during the first time duration, a first allocation;
- wherein:
- the first allocation comprises a first number of resource blocks;
- a transmission power capability of the wireless device is characterized by a resource block limit;
- the first number of resource blocks exceeds the resource block limit;
- and
- the data transmission is effected consistent with the transmission power capability.
A base station comprising:
- a receiver configured to receive a first resource allocation request from a wireless device, the first resource allocation request being responsive to a resource utilization limitation exceeding a reporting threshold for the wireless device;
- and
- a transmitter configured to send a dynamic resource allocation grant having a first time duration associated therewith, the grant comprising a first power control instruction configured to be used by the wireless device during the first time duration, a first allocation;
- wherein:
- the first allocation comprises a first number of resource blocks;
- a transmission power capability of the wireless device is characterized by a resource block limit;
- the first number of resource blocks exceeds the resource block limit;
- and
- the data transmission is effected consistent with the transmission power capability.
An apparatus comprising:
- a memory storing software instructions;
- and
- a processor configured to implement the software instructions to cause the apparatus to:
- receive a first resource allocation request from a wireless device, the first resource allocation request being responsive to resource utilization limitation exceeding a reporting threshold for the wireless device;
- and
- send a dynamic resource allocation grant having a first time duration associated therewith, the grant comprising a first power control instruction configured to be used by the wireless device during the first time duration, a first allocation;
- wherein:
- the first allocation comprises a first number of resource blocks;
- a transmission power capability of the wireless device is characterized by a resource block limit;
- the first number of resource blocks exceeds the resource block limit;
- and
- the data transmission is effected consistent with the transmission power capability.
