The invention discloses a power processing method, a communication device, a chip and module equipment thereof. The method comprises the following steps: receiving a first primary synchronization signal PSS of a cell to be accessed; performing correlation operation on the first PSS and a local PSS to obtain a first correlation power sequence; determining a first shift factor according to the first correlation power sequence; and according to the first shift factor, carrying out shift processing on the first correlation power sequence to obtain a first node power sequence. By implementing the method provided by the embodiment of the invention, the shift factor can be calculated in real time according to the received PSS, so that the accuracy of the power sequence of the first node is improved, the position of the PSS of the cell to be accessed is determined, and the downlink synchronization with the cell to be accessed is completed.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a power processing method, a communication device, a chip and module equipment thereof. Background technique [0002] During the cell search process, the terminal device may receive a primary synchronization signal (primary synchronization signal, PSS) from the cell to be accessed, and determine the location of the PSS to obtain the physical layer identifier of the cell to be accessed and complete downlink synchronization. Wherein, the terminal device can perform a correlation operation on the PSS received from the cell to be accessed and the local PSS, so as to determine the position of the PSS of the cell to be accessed by the position of the node power value exceeding the threshold value. Since the correlation power sequence obtained after the correlation operation has a wide bit width, a shift factor is usually configured by software to shift the correlati...
