Abstract
Techniques for adjusting transmit power to mitigate both intra-sector interference to a serving base station and inter-sector interference to neighbor base stations are described. This may be done by combining interference information from multiple base stations.
Claims44
A method of performing power control at a serving base station in communication with the wireless terminal, comprising:
- obtaining at the serving base station, for at least two sectors, an indication of interference observed by the sector, each sector being a neighbor sector not designated to receive a data transmission sent by the wireless terminal or a serving sector designated to receive the data transmission sent by the wireless terminal;
- combining each indication of interference received from the at least two sectors;
- and
- adjusting transmit power for the data transmission based upon the combined indications.
An apparatus at a serving base station operable to perform power control for a wireless terminal, comprising:
- a processor configured to obtain at the serving base station, for at least two sectors, an indication of interference observed by the sector, each sector being a neighbor sector not designated to receive a data transmission sent by the wireless terminal or a serving sector designated to receive the data transmission sent by the wireless terminal, and to adjust a transmit power for data transmission based upon combining each indication of interference received from the at least two sectors;
- and
- a memory coupled with the processor.
An apparatus at a serving base station operable to perform power control for a wireless terminal in a wireless communication system, comprising:
- means for obtaining at the serving base station, for at least two sectors, an indication of interference observed by the sector, each sector being a neighbor sector not designated to receive a data transmission sent by the wireless terminal or a serving sector designated to receive the data transmission sent by the wireless terminal;
- means for combining each indication of interference received from the at least two sectors;
- and
- means for adjusting transmit power for the data transmission based upon the combined indications.
A computer readable storage medium at a serving base station comprising code, which, when executed by a processor, direct the processor to perform power control for a wireless terminal in a wireless communication system, the computer readable storage medium comprising:
- code for obtaining at the serving base station, for at least two sectors, an indication of interference observed by the sector, each sector being a neighbor sector not designated to receive a data transmission sent by the wireless terminal or a serving sector designated to receive the data transmission sent by the wireless terminal;
- code for combining each indication of interference received from the at least two sectors;
- and
- code for adjusting transmit power for the data transmission based upon the combined indications.
