摘要： Techniques for sending and receiving signaling in a wireless communication system are described. Multiple (e.g., eight) vectors of modulation symbols may be defined and may be orthogonal to one another. Multiple subscriber stations may share transmission resources and may simultaneously send different vectors of modulation symbols in the same tile. Each subscriber station may be assigned multiple sets of at least one vector of modulation symbols usable by that subscriber station to convey signaling, e.g., one set of three vectors for acknowledgement (ACK) and another set of three vectors for negative acknowledgement (NAK). Each subscriber station may send one set of at least one vector in at least one tile to convey a signaling value. Different subscriber stations may simultaneously send different sets of at least one vector in the at least one tile to convey their signaling values.

摘要： Techniques for sending signaling in a wireless communication system are described. Multiple feedback channels may be multiplexed such that they can share time frequency resources. Each feedback channel may be allocated a different subset of subcarriers in each of at least one tile. In one design, a subscriber station may determine time frequency resources including first and second portions of time frequency resources for first and second feedback channels, respectively. The subscriber station may send vectors of modulation symbols of a first length on the first feedback channel and/or vectors of modulation symbols of a second length on the second feedback channel. A base station may receive the first and second feedback channels and may perform detection on vectors of received symbols for each feedback channel to recover the signaling sent on that feedback channel.

摘要： To select a rate for a transmitter in a communication system, a receiver obtains a channel response estimate and a received SINR estimate for the transmitter, e.g., based on a pilot received from the transmitter. The receiver computes a hypothesized SINR for the transmitter based on the channel response estimate and the received SINR estimate. The receiver then selects a rate for the transmitter based on (1) the hypothesized SINR and (2) characterized statistics of noise and interference at the receiver for the transmitter, which may be given by a probability density function (PDF) of SINR loss with respect to the hypothesized SINR. A look-up table of rate versus hypothesized SINR may be generated a priori for the PDF of SINR loss. The receiver may then apply the hypothesized SINR for the transmitter to the look-up table, which then provides the rate for the transmitter.
