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 provide techniques for managing persistent resource assignments in a wireless communication system. An access point can generate a bitmap by mapping access terminals having persistent assignments for traffic channels to a series of bitmap bits that provide keep-alive indications for the access terminals. The bitmap can then be provided as a common keep-alive message in a broadcast or multicast transmission to the access terminals. The keep-alive message can further include CRC bits for error prevention. An access terminal, upon receiving the keep-alive message, can then determine whether a bitmap bit in the keep-alive message corresponding to the access terminal conveys a keep-alive indication for the terminal and utilize its persistently assigned traffic channels accordingly.

摘要： Systems and methodologies are described that facilitate establishing a forward link acknowledgement channel and transmitting acknowledgment signals thereupon. In particular, the signals can be spread within contiguous channel clusters in a tile where the signals in the cluster are mutually orthogonal to one another. Additionally, the signals can be multiplexed over a plurality of frequency regions. In this regard, the acknowledgment signals are diverse with respect to frequency and interference; moreover, the signals can be received and decoded even where one of the channels experiences high interference. Furthermore, the acknowledgement signals can also communicate a channel deassignment value, which allows devices to utilize persistent channels in communicating data to one another

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.

摘要： Systems and methodologies are described that provide half-duplex communication in a frequency division duplex (FDD) system. Communications in an FDD system may be divided into half-duplex interlaces, wherein a terminal may receive at one time period and transmit at another time period. An access network in an FDD system may then utilize half-duplex communication to communicate with an access terminal that is not capable of transmitting and receiving simultaneously by using a half-duplex interlace. Further, an access network may also utilize full-duplex communication to communicate with an access terminal that is capable of transmitting and receiving simultaneously.

摘要： A shared signaling channel can be used in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system to provide signaling, acknowledgement, and power control messages to access terminals within the system. The shared signaling channel can be assigned to a predetermined number of sub-carriers within any frame. The assignment of a predetermined number of sub-carriers to the shared signaling channel establishes a fixed bandwidth overhead for the channel. The actual sub-carriers assigned to the channel can be varied periodically, and can vary according to a predetermined frequency hopping schedule. The amount of signal power allocated to the signaling channel can vary on a per symbol basis depending on the power requirements of the communication link. The shared signaling channel can direct each message carried on the channel to one or more access terminals. Unicast messages allow the channel power to be controlled per the needs of individual communication links.
