摘要： A technique for performing channel tracking and/or channel estimation in a wireless communication device includes receiving a reference signal and one or more non-error propagation physical channel signals. In general, the one or more non-error propagation physical channel signals must be correctly decoded before a data channel can be decoded. Channel tracking and/or channel estimation are/is then performed based on the reference signal and at least one of the one or more non-error propagation physical channel signals.

摘要： A technique for radio link detection in a wireless communication system includes estimating a first error rate of an indicator channel. In this case, the indicator channel includes an indication of a number of symbols in a control channel. A second error rate of the control channel is also estimated. The first and second error rates are then combined to provide a performance metric. Based on the performance metric, a determination is made as to whether a radio link problem exists.

摘要： A technique of operating a wireless communication device includes selecting, from a primary sequence group that includes respective primary sequences, one of the respective primary sequences as a first portion of a cell identification (ID). In this case, the respective primary sequences are each associated with respective secondary sequence subgroups included in a secondary sequence group. Each of the respective secondary sequence subgroups include secondary sequences. One of the secondary sequences is selected (from one of the respective secondary sequence subgroups that is associated with the selected one of the respective primary sequences) for a second portion of the cell ID. At least some of the secondary sequences are only included in one of the respective secondary sequence subgroups. The first portion of the cell ID is encoded on a first downlink waveform that is to be transmitted and the second portion of the cell ID is encoded on a second downlink waveform that is to be transmitted. The first and second downlink waveforms are then transmitted.
