摘要： Systems and methodologies are described that facilitate employing distributed frequency planning and reuse factor optimization based upon forward link and/or reverse link interference management techniques. An optimal reuse factor for a base station can be determined based upon a metric that evaluates levels of service associated with neighboring base stations. Moreover, a subset of available resource sets can be selected for use by the base station; thus, a base station specific collection of resource sets can be formed through such selection. Further, mappings of each resource set to a set of physical resources can be disseminated in a network or portion thereof. According to another example, frequency hopping can be constrained to use of resources within a resource set (rather than across more than one resource set) as provided in a base station specific hopping pattern.

摘要： Systems and methodologies are described that facilitate mitigating effect of non-linear distortion from a power amplifier on a spectral mask margin. Power limit indications can be analyzed in scheduling mobile devices. Mobile devices with power limits can be scheduled on inner subbands. The power limits can be based at least in part on power amplifier headroom information. Other mobile devices can employ remaining portions of an allocated spectrum. Further, mobile devices can evaluate and establish a power amplifier backoff based upon the subband scheduling.

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.

摘要： Transmission schemes that can flexibly achieve the desired spatial multiplexing order, spatial diversity order, and channel estimation overhead order are described. For data transmission, the assigned subcarriers and spatial multiplexing order (M) for a receiver are determined, where M≧1. For each assigned subcarrier, M virtual antennas are selected from among V virtual antennas formed with V columns of an orthonormal matrix, where V≧M. V may be selected to achieve the desired spatial diversity order and channel estimation overhead order. Output symbols are mapped to the M virtual antennas selected for each assigned subcarrier by applying the orthonormal matrix. Pilot symbols are also mapped to the V virtual antennas. The mapped symbols are provided for transmission from T transmit antennas, where T≧V. Transmission symbols are generated for the mapped symbols, e.g., based on OFDM or SC-FDMA. Different cyclic delays may be applied for the T transmit antennas to improve diversity.

摘要： Techniques for mitigating interference in a wireless communication system are described. In one design, a sector may determine multiple fast other sector interference (OSI) indications for multiple subzones, with each subzone corresponding to a different portion of the system bandwidth. At least one report may be generated for the multiple OSI indications, with each report including at least one OSI indication for at least one subzone. Each report may be encoded to obtain code bits, which may then be mapped to a sequence of modulation symbols. A sequence of modulation symbols of zero values may be generated for each report with all OSI indications in the report set to zero to indicate lack of high interference in the corresponding subzones. This allows a report to be transmitted with zero power in a likely scenario. A regular OSI indication may also be determined for the system bandwidth and transmitted.
