    摘要： Techniques for sending control information in a wireless communication system are described. A control segment may include L≧1 tiles, and each tile may include a number of transmission units. A number of control resources may be defined and mapped to the transmission units for the control segment. For symmetric mapping, multiple sets of S≧1 control resources may be formed, and each batch of L consecutive sets of S control resources may be mapped to S transmission units at the same location in the L tiles. For localized mapping, S>1, and each set of S control resources may be mapped to a cluster of S adjacent transmission units in one tile. For distributed mapping, S=1, and each control resource may be mapped to one transmission unit in one tile. For diversity, each control resource may be mapped to multiple (e.g., three) transmission units in at least one tile.

    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 supporting efficient operation by terminals in a wireless communication system are described. A base station transmits a preamble periodically in each superframe. The preamble includes at least one first OFDM symbol for control information followed by at least one second OFDM symbol for paging information. A terminal receives the first and second OFDM symbols and determines a receiver gain based on the received power of the first OFDM symbol(s), e.g., with an AGC loop having a shorter time constant than the duration of the first OFDM symbol(s). The terminal processes the second OFDM symbol(s) based on the receiver gain to obtain the paging information. The terminal may operate in an idle state, determine superframes assigned to the terminal, sleep between the assigned superframes, and process the first and second OFDM symbols in each assigned superframe to obtain the paging information.

    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.

    摘要： Systems and methodologies are described that facilitate communicating reverse link control information over OFDMA control channel(s) and CDMA control channel(s). Dedicated OFDMA control channel resources can be assigned to mobile device(s). Control information related to one or more logical control channels can be generated by a mobile device. Further, a physical control channel type (e.g., OFDMA control channel or a CDMA control channel) can be selected for sending the control information via the reverse link. For example, control information associated with periodic, logical control channels can be multiplexed and sent over the OFDMA control channel (e.g., utilizing the dedicated OFDMA control channel resources) while control information related to non-periodic, logical control channels can be transmitted over the CDMA control channel.

    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.
