Abstract: An apparatus comprises a detection processor (203) for detecting retransmission feedback messages in response to a detection threshold. A threshold processor (207) determines the detection threshold in response to a noise estimate generated by a noise processor (209). The noise processor comprises a sub-symbol generator (211) which divides a retransmission feedback symbol into a plurality of sub-symbols. Each of the sub-symbols is despread by a spreading code with a lower spreading factor than a spreading factor of the retransmission feedback symbol. A difference generator (213) then generates difference symbol values between the plurality of sub-symbols and a noise estimator (215) generates the noise estimate in response to the difference symbol values, for example by determining the variance of the difference symbol values. An improved noise estimate may be determined resulting in improved detection performance and thus improved retransmission performance.

Abstract: A system and method for to establish a wireless group call from one of a plurality of communication units to others communication units includes a first step of receiving, from a requesting communication unit a request for a group call with other communication units of the group. A next step includes allocating a common downlink channel for the group call. A next step includes allocating a dedicated uplink channel for the requesting communication unit. A next step includes switching one of the communication units between the common channel mode and a dedicated channel mode depending upon performance criteria.

Abstract: A method (400) and apparatus (501) provide for rapid power control based on a quality related value, e.g. channel quality indicator (CQI) value. A transmit power level can be derived from a CQI value received according to a time period, e.g. corresponding to 500 Hz. A first predicted value can be predicted based on the CQI value, at a first time within the time period and a power adjustment value can be determined based on the CQI value as well as the first predicted value at a rate that exceeds the rate of receiving the CQI values. Note that other predicted values for or corresponding to the CQI value can be predicted at other times within the time period and that power adjustment values can be determined through interpolation between predicted values for any time within the period.
