Abstract: For interference control, a sector m estimates interference observed from terminals in neighbor sectors and obtains an interference estimate. Sector m may generate an over-the-air (OTA) other-sector interference (OSI) report and/or an inter-sector (IS) OSI report based on the interference estimate. Sector m may broadcast the OTA OSI report to the terminals in the neighbor sectors. These terminals may adjust their transmit powers based on the OTA OSI report. Sector m may send the IS OSI report to the neighbor sectors, receive IS OSI reports from the neighbor sectors, and regulate data transmissions for terminals in sector m based on the received IS OSI reports. Sector m may control admission of terminals to sector m, de-assign admitted terminals, schedule terminals in sector m in a manner to reduce interference to the neighbor sectors, and/or assign the terminals in sector m with traffic channels that cause less interference to the neighbor sectors.

Abstract: The disclosed embodiments provide for methods and systems for selecting sectors for handoff in a communication system. According to one aspect, the method includes monitoring an indicia of transmit power on a plurality of RL control channels directed to a plurality of sectors, and selecting one of the sectors as a candidate for a RL handoff. The disclosed embodiments also provide for methods and systems for indicating a selected serving sector for handoff in a communication system. According to one aspect, the method includes sending a first signal to a first sector to indicate the first sector as a serving sector for a forward-link handoff, and sending a second signal to a second sector to indicate the second sector as a serving sector for a reverse-link handoff.

Abstract: An apparatus for performing power control in a communication system comprises: means for receiving a codeword via a first wireless link; means for computing an indication of confidence that the received codeword is correct where the indication is based on a determination of the Euclidean distance between the received codeword and each of a set of possible valid codeword; means for generating a message to adjust a power of the communication system based on whether the computed indication of confidence was within an erasure threshold; and means for transmitting said message on second wireless link.

Abstract: Techniques for performing erasure detection and power control for a transmission without error detection coding are described. For erasure detection, a transmitter transmits codewords via a wireless channel. A receiver computes a metric for each received codeword, compares the computed metric against an erasure threshold, and declares the received codeword to be "erased" or "non-erased". The receiver dynamically adjusts the transmit power based on whether the codewords met the erasure threshold or not.
