Power control for wireless communication systems
First Claim
1. An apparatus comprising:
- at least one processor configured to receive feedback for a first transmission sent on a reverse link, to adjust a reference power level based on the feedback, to receive interference information for a sector, and to determine transmit power for a second transmission being sent to the sector based on the interference information for the sector and the reference power level; and
a memory coupled to the at least one processor.

Abstract
Techniques for controlling transmit power of a terminal are described. The terminal may send a first transmission (e.g., for pilot or signaling) on the reverse link, receive feedback (e.g., a power control command or an erasure indicator) for the first transmission, and adjust a reference power level based on the feedback. The terminal may also receive interference information and possibly other parameters such as a pilot quality indicator (PQI), an offset factor, and a boost factor from a sector. The terminal may determine transmit power for a second transmission to the sector based on the interference information, the reference power level, and/or the other parameters. The terminal may receive the feedback from one sector and may send the second transmission with CDMA or OFDMA to the same sector or a different sector.

29. An apparatus comprising:
-
at least one processor configured to receive a first transmission from a terminal on a reverse link, to generate feedback based on the first transmission, to estimate interference at a sector and obtain interference information for the sector, to send the feedback and the interference information to the terminal, and to receive a second transmission sent by the terminal to the sector at a transmit power determined based on the feedback and the interference information for the sector; and a memory coupled to the at least one processor. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37)
