    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： Methods and apparatus for increasing diversity gain at a receiver by applying beamforming to transmit diversity space-time coded signals. A transmit signal is space-time coded over a plurality of space-time antenna groups, with each space-time antenna group associated with a specific space-time code. The signal at each space-time antenna group is beamformed over the plurality of antenna in the space-time antenna group. Each of the plurality of antenna in a space-time antenna group is weighted with a distinct weight, relative to the other antenna in the space-time group. The beamforming weights can vary based on a channel quality feedback indication from a receiver. The amplitude, phase, or a combination of amplitude and phase of each weight or of a vector of multiple weights can vary as a function of the channel quality indication in order to improve the quality of the received signal.

    摘要： Methods and apparatus for increasing diversity gain at a receiver by applying beamforming to transmit diversity space-time coded signals. Transmit diversity can be provided at a signal source by space-time coding the signal. A transmit signal is space-time coded over a plurality of space-time antenna groups, with each space-time antenna group associated with a specific space-time code. The signal at each space-time antenna group is beamformed over the plurality of antenna in the space-time antenna group. Each of the plurality of antenna in a space-time antenna group is weighted with a distinct weight, relative to the other antenna in the space-time group. Each weight can have a distinct amplitude, phase, or combination of amplitude and phase. The weights can be static or dynamic. The dynamic weights can vary amplitude, phase, or a combination of amplitude and phase of each weight over time.

    摘要： A method for efficiently performing ranging in a wireless communication network may be implemented by a mobile station. The method may include sending a ranging code to a base station. The method may also include receiving a ranging response message from the base station. The method may also include determining whether a ranging failure condition is satisfied. The ranging failure condition may relate to something other than a duration of time. The method may further include re-sending the ranging code to the base station if the ranging failure condition is satisfied.
