Abstract: A method is disclosed that includes measuring, during a measurement period, values corresponding to noise and interference signals received from a channel. The measurement period coincides with a period when no signal is transmitted on the channel. The method also includes determining one or more thresholds based upon the measured values. Second signals that correspond to a message are received on the channel. The message includes an indicator having a number of possible states. A value is determined corresponding to the indicator based upon the second signals. One of the possible states is assigned to the indicator of the received message based upon the one or more thresholds and the determined value.

Abstract: There is provided a receiver comprising: an estimator configured to estimate an initial noise-plus-interference covariance matrix on the basis of a received signal; a calculator configured to calculate a parameter using the received signal; and a calculator configured to decrease magnitude of off-diagonal values of the estimated initial covariance matrix relative to diagonal values of the same matrix based on the calculated parameter in order to estimate a final noise-plus-interference covariance matrix.

Abstract: In one exemplary embodiment, method including: receiving a first wireless communication with at least a first and second receiver utilizing a diversity method; and, in response to determining that simultaneous reception of a second wireless communication is desired, signaling that at least the second receiver is to be unavailable for the first communication. In another exemplary embodiment, method including: receiving a first wireless communication with at least a first receiver; receiving a second wireless communication with at least a second receiver; and in response to determining that reception of the second communication is to end, signaling that at least the second receiver is to be available for use. In another exemplary embodiment, method including: receiving, by a first apparatus, a timing of a second apparatus' periodic reception; and adjusting a transport format of a wireless communication sent from the first apparatus to the second apparatus based on the timing.

Abstract: A method and system for estimating the signal-to-interference plus noise ratio (SINR) of the common pilot channel (CPICH) in a W-CDMA receiver. The SINR estimation is carried out after chip level filtering and then the despreading of the CPICH channel. In the case of space-time transmit diversity, a virtual space-time decoding is used on the CPICH channel in order to mimic data channel data channel space-time transformation. The estimated SINR can be used for a User Equipment to report its channel quality indicator to a Node B.
