摘要： System(s) and method(s) are provided to facilitate generating and processing acquisition pilots in wireless communications. Acquisition pilots that convey timing and frequency synchronization information, wireless system acquisition and system determination information are modulated with pseudorandom sequences. The R bits of information carried by the acquisition pilot that conveys system determination information are augmented with T bits that convey a counter index associated with the system timing of superframes transmitted from an access point. The processing overhead resulting from the addition of the T bits is offset by the advantages afforded to a wireless communication. Salient advantages include: (i) processing gain at a receiver for communication in a specific sector during asynchronous operation, (ii) packet boundary determination through the counter field values, and (iii) initialization of various pseudorandom registers employed for communication.

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： Systems and methodologies are described that facilitate grouping pilot identifies to indicate type and/or classification information regarding one or more access points. The access points can select or be assigned pilot identifiers from the group indicating a type or classification related to the access points. Thus, identifiers can be grouped into macrocell and/or femtocell groups or ranges such that an access point can indicate, and mobile devices can efficiently determine, whether the access point provides macrocell or femtocell coverage based on a range from which its pilot identifier is selected or assigned. In addition, the pilot identifiers can be utilized to indicate restricted association information regarding the access points.

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.
