Abstract: A communication device can be configured to estimate a Reference-Signal-Received-Power (RSRP). The communication device can include a transceiver and a controller. The transceiver can be configured to downsample a received signal having a plurality of reference signal resource elements to generate a downsampled signal. The downsampling can alias a first of the plurality of reference signal resource elements into a second of the plurality of reference signal resource elements to generate an aliased reference signal resource element. The transceiver can also be configured to extract the aliased reference signal resource element from the downsampled signal. The controller can be connected to the transceiver and be configured to estimate the RSRP based on the extracted aliased reference signal resource element.

Abstract: A communication circuit arrangement may include a cell search circuit configured to compare a detected synchronization sequence of a detected candidate cell with a predetermined reference synchronization sequence to generate a demodulated synchronization sequence including a plurality of samples, determine a phase variance between the plurality of samples of the demodulated synchronization sequence, and compare the phase variance to a detection threshold to classify the detected candidate cell as a real cell or a false cell.
