摘要： Techniques for transmitting and receiving data in a relay communication network are described. Stations in the relay network may be grouped into multiple depths. Packets may be transmitted in a pipelined manner, with stations at progressively higher depth sending transmissions of a packet in successive frames. In an aspect, a station may receive data with interference cancellation. The station may obtain a received signal containing transmissions of a first packet from stations at a first depth and transmissions of a second packet from stations at a second depth. The first and second stations may be downstream and upstream stations, respectively, or may be upstream stations at different depths. The station may estimate and cancel interference due to the transmissions of the first packet from the received signal to obtain an interference canceled signal. The station may then process the interference canceled signal for the second packet.

摘要： Systems and methodologies are described that facilitate synchronizing base stations in a wireless communication environment. A base station can receive a synchronization signal sent via a low reuse channel, which can be shared by a group of base stations. Further, the base station can align a clock associated therewith to the received synchronization signal. Moreover, the base station can coarsely align the clock to a first synchronization signal received upon a first subset of resources of the low reuse channel, and finely align the clock to a second synchronization signal received upon a second subset of resources (e.g., of the low reuse channel, of a separate channel, ...), where the second subset of resources can be reserved for transmission from at least one base station with at least a predetermined level of synchronous accuracy.

摘要： Techniques for mitigating interference in an asynchronous wireless network are described. A terminal may desire to communicate with a serving base station and may observe high interference from other base stations. In an aspect, some frequency resources may be reserved for sending reduce interference requests and pilots to support interference mitigation. In one design, a first station (e.g., a terminal) may send a request to reduce interference to at least one interfering station on reserved control resources. The first station may receive a pilot sent by each interfering station on reserved pilot resources. The reserved resources may be associated with data resources. The first station may estimate received signal quality of the data resources based on the pilot(s). The first station may receive data sent on the data resources by a second station (e.g., a serving base station) after the interfering station(s) have reduced interference.

摘要： Systems and methodologies are described that facilitate utilizing different power control algorithms as a function of access terminal speed. For instance, instantaneous Channel Quality Indicator (CQI) reports can be inverted for slow moving access terminals while long-term geometry inversion (e.g., average CQI report inversion) can be utilized for quick moving access terminals. Speed of the access terminal can be estimated based upon time correlation of CQI values. Further, selection of implementing instantaneous CQI inversion or long-term geometry inversion can be based upon the estimated speed of the access terminal.

摘要： Techniques for sending acknowledgement (ACK) information for data transmission are described. In one design, a receiver receives a transmission of data, processes the received transmission to decode the data, and generates ACK information for the data prior to decoding all of the data. The receiver may generate the ACK information based on decoding results for a portion of the data and/or received signal quality of the received transmission. The receiver may send the ACK information at a designated ACK transmission time prior to completing decoding for all of the data. The receiver may receive a transmission of multiple (K) packets and may generate ACK information for these K packets after decoding L packets, where 1= L

摘要： Techniques for encoding and decoding data are described. In an aspect, multiple code rates for a forward error correction (FEC) code may be supported, and a suitable code rate may be selected based on packet size. A transmitter may obtain at least one threshold to use for code rate selection, determine a packet size to use for data transmission, and select a code rate from among the multiple code rates based on the packet size and the at least one threshold. In another aspect, multiple FEC codes of different types (e.g., Turbo, LDPC, and convolutional codes) may be supported, and a suitable FEC code may be selected based on packet size. The transmitter may obtain at least one threshold to use for FEC code selection and may select an FEC code from among the multiple FEC codes based on the packet size and the at least one threshold.

摘要： Systems and methodologies are described that generate pilots for signal acquisition in a wireless communication system based on time domain sequences. The pilots may be generated by a base station and transmitted in a pilot field to one or more access terminals to aid in signal acquisition at each of the access terminals. One of the pilots may be common to all access points in the wireless communication system, thereby allowing an access terminal to obtain a timing estimate for the system while minimizing the effects of interference variations between base stations. Further, one or more generated pilots may be unique to each access point in order to allow each respective access point to be identified by its generated pilots.
