Abstract: The present invention is a method and apparatus for resource allocation signaling for grouping user real time services. Uplink signaling for voice activity reporting of each user's transition between an active state and an inactive voice state is sent from a wireless transmit/receive unit to a Node B. Radio resource allocation to users of a wireless communication system varies based on user measurement reporting, a pre-determined pattern such as frequency hopping, or a pseudorandom function. Grouping methods are adjusted to better utilize the voice activity factor, so that statistical multiplexing can be used to more efficiently utilize physical resources.

Abstract: A method for transmitting an ACK/NACK symbol includes transmitting a same ACK/NACK symbol in both a first reference symbol and a second reference symbol in a slot. An apparatus to transmit an ACK/NACK symbol includes an ACK/NACK symbol generator, and a transmitter to transmit a modulated first reference symbol modulated by a first ACK/NACK symbol in a first reference symbol long block of a first slot, and to transmit a modulated second reference symbol modulated by the first ACK/NACK symbol in a second reference symbol long block of the first slot. Antenna diversity may be applied in successive slots or between the first and second reference symbols in a slot. A switching pattern to the modulation of the first and/or second reference symbol may be applied.
