摘要： Techniques for using virtual noise figure for various functions in a wireless communication network are described. A virtual noise figure is an indication of a virtual noise level at a receiver, which may be higher than an actual noise level at the receiver. In an aspect, virtual noise figure may be used for serving base station selection. A terminal may receive information indicative of a virtual noise figure for each of at least one base station. The terminal may select a serving base station based on the virtual noise figure for each base station. The terminal may send data to the serving base station at a rate selected based on an actual noise figure for the serving base station. In other aspects, virtual noise figure may be used for interference management and/or power control.

摘要： Techniques for mitigating interference in a wireless communication network are described. A terminal may desire to communicate with a weaker serving base station and may observe high interference from a strong interfering base station. The two base stations may be asynchronous and have different frame timing. In an aspect, high interference may be mitigated by having the interfering base station reserve downlink and/or uplink resources. The interfering base station may transmit at a low power level or not at all on the reserved downlink resources to reduce interference to the terminal. Terminals served by the interfering base station may transmit at a low power level or not at all on the reserved uplink resources to reduce interference at the serving base station. The terminal may then be able to communicate with the serving base station.

摘要： Techniques for sending low reuse preambles in a wireless network are described. In an aspect, a base station may send a low reuse preamble on reserved frequency resources to allow terminals to detect the base station even in the presence of strong interfering base stations. The base station may generate the low reuse preamble to include a pilot portion and a data portion. The base station may determine frequency resources reserved for sending low reuse preambles by base stations. The base station may then send the low reuse preamble on the reserved frequency resources, e.g., at a pseudo-randomly selected time. A terminal may detect for low reuse preambles sent by the base stations on the reserved frequency resources. The terminal may recover information for a base station from a detected low reuse preamble.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a serving base station may send a message to a terminal to trigger short-term interference mitigation. In response, the terminal may send a message to request at least one interfering base station to reduce interference on at least one resource. Each interfering base station may determine a transmit power level to be used for the at least one resource and may send a pilot at this transmit power level. The terminal may estimate the channel quality of the at least one resource based on at least one pilot received from the at least one interfering base station. The terminal may send information indicative of the estimated channel quality to the serving base station. The serving base station may send a data transmission on the at least one resource to the terminal.

摘要： Techniques for transmitting data with short-term interference mitigation in a wireless communication system are described. In one design, a first station (e.g., a base station or a terminal) may send a first message to at least one interfering station to request reduction of interference on at least one resource. The first station may send the first message in anticipation of receiving data on the at least one resource. An interfering station may receive the first message from the first station and may reduce interference on the at least one resource by reducing its transmit power and/or by steering its power in a direction different from the first station. The first station may thereafter receive data from a second station on the at least one resource. The techniques may be used for data transmission on the forward and reverse links.

摘要： Signaling-only access may be established with an access node under certain circumstances such as, for example, upon determining that a node is not authorized for data access at the access node. A node that is not authorized for data access at an access node may still be paged by the access node through the use of signaling-only access. In this way, transmissions by the access node may not interfere with the reception of pages at the node. A first node may be selected for providing paging while a second node is selected for access under certain circumstances such as, for example, upon determining that the second node provides more desirable service than the first node.

摘要： Systems and methodologies are described that facilitate selecting and/or reselecting one or more access points, related cells, or carriers based at least in part on calculating an energy efficiency related to the access points. In particular, the energy efficiency can be based at least in part on an estimated pathloss and/or a level of interference related to communicating with the access points. Moreover, load parameters related to the access point can be received and evaluated in selecting and/or reselecting the access point. Thus, access points can be selected or reselected based on parameters other than forward link transmit power. In addition, pathloss and/or interference levels can be weighed based on access point type to prevent macrocell overloading.

摘要： Techniques for transmitting information using beacon symbols in a wireless communication system are described. In one design, a transmitter may map information to multiple subcarriers among a plurality of subcarriers, with the information being conveyed by the position of the multiple subcarriers. The transmitter may map the information to at least one non-binary symbol. The transmitter may then determine each of the multiple subcarriers based on one non-binary symbol or may determine all of the multiple subcarriers based on one non-binary symbol. The transmitter may generate a beacon symbol having the information mapped to the multiple subcarriers. The transmitter may use higher transmit power for the multiple subcarriers to allow receivers with low geometry to reliably receive the information. The use of multiple subcarriers may allow more information to be sent in the beacon symbol and may also improve frequency diversity.
