摘要： Techniques for sending control messages are described. In an aspect, assignment messages may be acknowledged based on either linked or dedicated acknowledgement (ACK) resources. A terminal may receive an assignment message from a base station, determine whether to acknowledge the assignment message, and determine ACK resources to use to acknowledge the assignment message. The ACK resources may be linked to a control block on which the assignment message was received, linked to resources given by the assignment message, or assigned to the terminal. The terminal may send the acknowledgement on the ACK resources. In another aspect, a control message may be acknowledged based on ACK resources determined based on the control message or the control block. The ACK resources may be linked to resources assigned by the control message or linked to the control message. The terminal may send an acknowledgement for the control message on the ACK resources.

摘要： Techniques for transmitting pilot and traffic data are described. In one aspect, a terminal may scramble its pilot with a scrambling sequence generated based on a set of static and dynamic parameters. The static parameter(s) have fixed value for an entire communication session for the terminal. The dynamic parameter(s) have variable value during the communication session. The terminal may generate a scrambling sequence by hashing the set of parameters to obtain a seed and initializing a PN generator with the seed. The terminal may then generate the pilot based on the scrambling sequence. In another aspect, the terminal may use different scrambling sequences for pilot and traffic data. A first scrambling sequence may be generated based on a first set of parameters and used to generate the pilot. A second scrambling sequence may be generated based on a second set of parameters and used to scramble traffic data.

摘要： Systems and methodologies are described that provide techniques for performing adjustments for delta-based power control and interference management in a wireless communication system. A terminal can utilize one or more delta-based power control techniques described herein upon engaging in a reverse link transmission after a predetermined period of silence or after receiving indications of interference from neighboring access points. A delta value can be computed through open-loop projection, based on which transmission resources such as bandwidth and/or transmit power can be increased or decreased to manage interference caused by the terminal. A delta value, other feedback from the terminal, and/or indications of interference caused by the terminal can also be communicated as feedback to a serving access point to allow the access point to assign transmission resources for the terminal.

摘要： Systems and methodologies are described that provide support for signal acquisition in wireless communication systems that utilize half-duplex communication in the presence of asynchronous sectors. Forward link and reverse link superframes can be structured such that a given frame position in a superframe alternates between forward link communication and reverse link communication for a particular half-duplex interlace. More particularly, an odd number of frames can be grouped into respective forward link and reverse link superframes, from which frames can be assigned to a first half-duplex interlace and a second half-duplex interlace in an alternating fashion. By varying the communication link used by a half-duplex interlace at a given frame location, terminals operating on a single half-duplex interlace can detect asynchronously operating sectors irrespective of the transmission timeline of such sectors.

摘要： Techniques for allocating and mapping resources in a wireless communication system are described. The system may use hop-ports to facilitate allocation and use of subcarriers. In one aspect, the hop-ports may be partitioned into multiple subzones, with each subzone including a configurable number of hop-ports. The hop-ports within each subzone may be permuted or shuffled based on a permutation function. After permutation, the hop-ports in all subzones may be mapped to the subcarriers based on local or global hopping. In another aspect, a set of hop-ports may be mapped to a set of subcarriers. A hop-port may be mapped to an unavailable subcarrier and may then be remapped to another available subcarrier. In yet another aspect, a set of hop-ports may be mapped to a set of subcarriers distributed (e.g., evenly) across all subcarriers but avoiding subcarriers in a reserved zone.

摘要： Systems and methodologies are described that provide interlace-based scheduling for control channels in a wireless communication system. One or more control channels for communication between a base station and a mobile terminal in the wireless communication system may be scheduled on one or more frame interlaces in the system based on one or more conditions of each frame interlace in the system. These conditions may include overhead balance between the frame interlaces, processing timeline optimization for the frame interlaces at the scheduling base station, and the desirability of discontinuous transmission (DTX) at a mobile terminal.

摘要： Techniques for controlling transmit power of a terminal are described. The terminal may send a first transmission (e.g., for pilot or signaling) on the reverse link, receive feedback (e.g., a power control command or an erasure indicator) for the first transmission, and adjust a reference power level based on the feedback. The terminal may also receive interference information and possibly other parameters such as a pilot quality indicator (PQI), an offset factor, and a boost factor from a sector. The terminal may determine transmit power for a second transmission to the sector based on the interference information, the reference power level, and/or the other parameters. The terminal may receive the feedback from one sector and may send the second transmission with CDMA or OFDMA to the same sector or a different sector.

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.
