Abstract: The disclosure relates to performing phase compensation at a transmitter. A processing device for a network access node generates a phase compensated modulation symbol based on at least one first modulation symbol and at least on one of a frequency offset parameter and a time offset parameter. The frequency offset parameter may be determined based on an offset between a reference frequency f0 and a DC (0 Hz) frequency such that the frequency offset parameter corresponds to the reference frequency f0. Also, the reference frequency f0 can be at least partly based on the carrier of up-conversion frequency used by the processing device and the reference frequency f0 can be the carrier for up-conversion frequency. The phase compensated symbol is transmitted to a receiver, such as a client device. Furthermore, the disclosure also relates to corresponding methods and a computer program.

Abstract: A method includes selecting N cells waiting to be camped on from a candidate cell list, decoding a Physical Broadcast Channel (PBCH) of each of the selected N cells waiting to be camped on, selecting, from at least one cell whose PBCH is successfully decoded, one cell as a cell continuing waiting to be camped on, and when a remaining minimum system information (RMSI) decoding result of the cell continuing waiting to be camped on indicates that the cell continuing waiting to be camped on meets a camping criterion, determining the cell continuing waiting to be camped on as the cell to be camped on.

Abstract: Embodiments of the present invention provide a method and terminal for a cell search that are related to the communications field. The terminal includes: two spaces, a first processing module, a first processing unit, and a second processing unit. The present invention can ensure that a cell search result exists in each time unit, thereby accelerating an initial search and shortening an initial search delay.
