摘要： 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, recieve 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.

摘要： 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. The amount of inter-sector interference that a terminal may cause may be roughly estimated based on the total interference observed by each neighbor base station, channel gains for the serving and neighbor base stations, and the current transmit power level. The transmit power may be decreased if high interference is observed by a neighbor base station and increased otherwise. The transmit power may be adjusted by a larger amount and/or more frequently if the terminal is located closer to the neighbor base station observing high interference and/or if the current transmit power level is higher, and vice versa. The intra-sector interference is maintained within an acceptable level by limiting a received SNR for the terminal to be within a range of allowable SNRs.

摘要： Systems and methods are described that facilitate controlling transmission/reception time slots in a wireless multi-hop ad hoc network. A node, such as an access terminal or an access point, may select an identifier that corresponds to specific time slots during which nodes with that particular identifier may transmit and/or receive. Nodes that are one hop away from each other may select different identifiers in order to ensure that neighboring nodes do not transmit and/or receive during the same time slots. In this manner, interference caused and/or experienced by a given node may be reduced.

摘要： Techniques for selecting a reverse link (RL) serving base station for a terminal are described. The terminal sends a transmission on the reverse link to multiple base stations in a wireless communication system. The transmission may be for signaling sent on a control channel. The terminal receives feedback (e.g., power control (PC) commands and/or erasure indications) from the multiple base stations. Each base station may generate feedback based on the control channel and/or some other transmission received from the terminal. The terminal performs reverse link power control and further selects an RL serving base station based on the received feedback. For example, the terminal may select the base station with the lowest transmit power level, the largest percentage of power down commands, or the lowest erasure rate as the RL serving base station.

摘要： Systems and methodologies are described that facilitate mitigating a hidden node condition in a wireless mesh network wherein nodes utilize a request-to-send/clear-to-send (RTS/CTS) protocol in conjunction with an asynchronous hybrid automatic repeat request protocol. For instance, a node may contend for a set of subcarriers by sending an RTS signal over the desired subcarriers, and may receive a CTS signal over the contended subcarriers, wherein the CTS signal indicates which subcarriers the node may transmit data over. If another node has won the contention for a particular subcarrier, requesting node may adjust a power level at which it transmits an RTS or a data packet in order to permit the requesting node to utilize the subcarrier without interfering with the winning node.
