    Abstract: Techniques for sending and receiving signaling in a wireless communicatio n system are described. Multiple (e.g., eight) vectors of modulation symbols may be defined and may be orthogonal to one another. Multiple subscriber st ations may share transmission resources and may simultaneously send differen t vectors of modulation symbols in the same tile. Each subscriber station ma y be assigned multiple sets of at least one vector of modulation symbols usa ble by that subscriber station to convey signaling, e.g., one set of three v ectors for acknowledgement (ACK) and another set of three vectors for negati ve acknowledgement (NAK). Each subscriber station may send one set of at lea st one vector in at least one tile to convey a signaling value. Different su bscriber stations may simultaneously send different sets of at least one vec tor in the at least one tile to convey their signaling values.

    Abstract: Methods and apparatuses that apply a time-varying delay to symbols to be transmitted from one or more antennas are provided. In a first embodiment, first and second transmission orders for samples in first and second data symbols, respectively, are determined. First and second cyclic prefixes are appended to the beginnings of the first and second transmission orders, respectively. The first and second data symbols are then provided to the same antenna for transmissions beginning at different time slots in accordance with a delay diversity scheme. In a second embodiment, either the first data symbol or the second data symbol can be provided to different antennas for transmissions beginning at different time slots in accordance with a delay diversity scheme.
