    Abstract: PROBLEM TO BE SOLVED: To provide a channel estimation method which reduces estimation error even in the edge of a given subband.SOLUTION: Pilot signals are received (504) within a given subband. A determination is made as to whether a subcarrier of interest is near the edge of a subband. If the given carrier is near the edge of a subband, pilot signals received in a neighboring subband are utilized (508). The pilot signals of the entire neighboring subband or a predetermined portion of the neighboring subband are utilized to estimate the channel response (512). If the assigned subcarrier is not near the edge of a subband, neighboring pilots need not be considered and the channel response is estimated (512) without the use of pilot signals in neighboring subbands.

    Abstract: PROBLEM TO BE SOLVED: To facilitate management of wireless communications in a large-scale heterogeneous wireless access point (AP) environment.SOLUTION: A preamble of a wireless signal (or, e.g., other data of the wireless signal where suitable) can be transmitted with low resource re-use (or low re-use), referred to as a low re-use preamble (or low re-use data transmission). By way of example, system data of an over-the-air message can be configured to include information identifying a distinct type of transmitting base station. In some aspects, the information can include an access type of the base station and/or a sector ID for distinguishing the base station among large numbers of other base stations. According to other aspects, the information can include wireless channel resources designated for a particular type of base station, or blanked by the transmitting base station, to facilitate interference reduction on such resources.

    Abstract: PROBLEM TO BE SOLVED: To provide dynamic resource allocation systems, apparatus, and methods for selectively improving the ability of a receiver to determine a channel estimate in an OFDMA system.SOLUTION: A wireless communication system 100 can use a common pilot channel configuration to aid channel estimation in receivers in communication with the system. A receiver may be unable to demodulate received data due to an inaccurate channel estimate. The receiver can communicate to a transmitter in the system a request for additional channel estimation resources. The wireless communication system can provide additional channel estimation resources by inserting dedicated pilot channels into one or more of the frequencies allocated to symbols for the receiver. If the receiver is still unable to demodulate the received data, the wireless communication system can incrementally insert additional pilot channels in the symbol associated with the receiver.

    Abstract: PROBLEM TO BE SOLVED: To provide techniques of allocating and mapping resources in a wireless communication system.SOLUTION: The system uses hop-ports to facilitate allocation of subcarriers. In one aspect, the hop-ports are partitioned into multiple subzones, with each subzone including a configurable number of hop-ports. The hop-ports within each subzone are permuted based on a permutation function. After the permutation, the hop-ports in all subzones are mapped to the subcarriers based on local or global hopping. In another aspect, a set of hop-ports is mapped to a set of subcarriers. A hop-port is mapped to an unavailable subcarrier and then remapped to another available subcarrier. In yet another aspect, a set of hop-ports is mapped to a set of subcarriers distributed across all subcarriers but avoiding subcarriers in a reserved zone.

    Abstract: PROBLEM TO BE SOLVED: To provide techniques for performing adjustments for interference management and delta-based power control in a wireless communication system.SOLUTION: A terminal can utilize one or more delta-based power control techniques 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.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate serving sector directed transmit power control in a wireless communication environment.SOLUTION: Under certain conditions, an access point can have better data with which to determine appropriate power levels than an individual terminal. Accordingly, an access point can transmit power control information to one or more terminals supported by the access point overriding normal power determination procedures. In particular, power control information can be included within an assignment message that designates resources (e.g., frequency, time) assigned to a terminal. Power control information can be based upon SNR, quality of service requirements, interference information, any other relevant information or any combination thereof.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus which improves quality of communications, power efficiency, etc. to address growing demands in CDMA wireless systems.SOLUTION: In a communication system where a CDMA segment at each access point consists of multiple sub-segments, a three frame transmission time interval (TTI) with eight retransmissions is utilized for data transmission. The access point not only specifies the interlaces to be utilized for data transmission but also assigns packet start interlaces for particular access terminals. An auxiliary pilot channel R-AuxPICH is transmitted by an access terminal along with CDMA data on a reverse link. The ratio of R-AuxPICH to R-PICH is varied based on ACK/NACK feedback. The apparatus sets reverse link activity bits (RABs) as an emergency load-control mechanism for non-QoS flows and includes a transmitter which broadcasts the RABs.
