Abstract: A wireless communication method includes: receiving a wireless signal including a plurality of frames, wherein each of the plurality of frames includes a plurality of sub-frames and a current frame is initially a first one of the frames; a) performing a correlation calculation between each of the sub-frames of the current frame and each a plurality of reference signals to generate a plurality of current correlation values; b) respectively accumulating the current correlation values with previous correlation values to generate cumulative values respectively corresponding to the plurality of sub-frames of the current frame; determining whether an effective synchronization signal is detected, based on the current cumulative values; and setting the current frame to a next one of the frames, setting the previous correlational values to the current correlation values, and determining whether to resume to step a) based on the determination as to whether the effective synchronization signal is detected.

Abstract: Apparatuses, methods, and systems of measuring received power are described, including apparatuses, methods, and systems which can measure received power, even when the subcarrier offset of the measurement bandwidth is different from the subcarrier bandwidth of the cell bandwidth. A method includes receiving, via a transceiver, first channel state information including a first index associated with first subcarrier offset information from a first Base Station (BS); receiving, via the transceiver, a plurality of Resource Blocks (RBs) from a second BS; configuring a second index associated with the plurality of RBs, instead of the first index, when the first index is different from the second index; measuring a received power based on the plurality of RBs from the second BS by using the second index; and identifying the measured received power as a valid received power.

Abstract: A chip for detecting a synchronization signal generated based on one of a plurality of sequences, which is generated by a sequence generator, the chip including a memory, and a processor connected to the memory may be provided. The processor may be configured to receive the synchronization signal, perform first descrambling the received synchronization signal for a first sequence from among the plurality of sequences by multiplying the received synchronization signal by the first sequence, and perform second descrambling the received synchronization signal for a second sequence, which is a complex conjugate of the first sequence, from among the plurality of sequences of the received synchronization signal by changing a sign of at least one element of a descrambled sequence of the first sequence.
