Abstract: A communication apparatus determines a serving cell that can perform information synchronization with a to-be-activated SCell, where the serving cell is an activated cell or a known cell. The communication apparatus determines a first SSB in SSBs sent by the to-be-activated SCell, where the first SSB corresponds to a second SSB sent by the serving cell. The communication apparatus activates the to-be-activated SCell based on the first SSB sent by the to-be-activated SCell and timing information and beam information of the second SSB.

Abstract: This application provides a transmission method and a transmission apparatus, so that a receive end can correctly demodulate data. A transmission method may include performing a phase compensation operation of a corresponding frequency value on each of m first signals in k signals, to obtain m second signals, where each of the m first signals is located at a non-center frequency of a current carrier, each first signal is a synchronization signal or data, m and k each are a positive integer, and m≤k. The method may also include performing sending processing on the m second signals.

Abstract: A paging indication method includes: generating a PEI, where the PEI indicates whether there is a paging message sent to a terminal on one or more POs; determining a time frequency region for sending the PEI, where the time frequency region corresponds to a synchronization signal block (SSB), a first interval is different from a second interval, the first interval is an interval between a start subcarrier of the PEI and a start subcarrier of the SSB, and the second interval is an interval between a start subcarrier of a secondary synchronization signal (SSS) and the start subcarrier of the SSB; and sending, in the time frequency region, the PEI to the terminal.

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: Embodiments of this application provide a synchronization signal/physical broadcast channel block (SSB) measurement method and an apparatus. One example method includes that a terminal device receives first information and second information. The first information indicates a time domain position of an SSB sent by a serving cell, and the second information indicates a set of SSBs that the terminal device needs to measure and that are sent by a neighboring cell. The terminal device measures, in a first measurement window based on the first information, the SSB sent by the serving cell. The terminal device measures, in a second measurement window based on the second information, the SSB sent by the neighboring cell.
