Description

Communication method and communication device Technical Field The present application relates to the field of communications, and more particularly, to a communication method and a communication apparatus. Background In a non-terrestrial communication network (non-TERRESTRIAL NETWORKS, NTN) scenario, a beam-hopping satellite communication system has been developed in order to alleviate the contradiction between small single-satellite load and wide coverage. Specifically, in a beam hopping satellite system, a single satellite is equipped with only a small number of beams (e.g., tens of beams) that serve all coverage areas of the single satellite in a time-sharing manner. In order to achieve energy saving, communication devices in a cell can transmit based on configured discontinuous transmission patterns (such as data transmission, control information transmission or reference signal transmission), and in the existing standard, the same discontinuous transmission patterns are configured for all communication devices in the cell, but in the NTN scenario, because the number of areas covered by a single satellite is large and all areas in the cell cannot be served at the same time, how to enable the communication devices in the cell to use the correct discontinuous transmission patterns for data transmission is a problem to be solved. Disclosure of Invention The application provides a communication method and a communication device, by which communication equipment in a cell can use a correct discontinuous transmission pattern for data transmission. In a first aspect, a communication method is provided, which may be executed by a communication device or a module (e.g., a processor, a chip, or a circuit, etc., or may be a logic module, hardware, and/or software that may implement all or part of the functionality of the communication device) applied to the communication device. The method comprises the steps of receiving information of M discontinuous transmission patterns and N pieces of adjustment quantity information, wherein each discontinuous transmission pattern in the M discontinuous transmission patterns corresponds to one or more pieces of adjustment quantity information in the N pieces of adjustment quantity information, the adjustment quantity information is used for adjusting the corresponding discontinuous transmission pattern, the M discontinuous transmission patterns comprise first discontinuous transmission patterns, the first discontinuous transmission patterns correspond to P pieces of adjustment quantity information in the N pieces of adjustment quantity information, the P pieces of adjustment quantity information comprise first adjustment quantity information, M and N are integers which are larger than or equal to 1, N is larger than or equal to M, P is smaller than or equal to N, and data transmission is carried out according to second discontinuous transmission patterns, and the second discontinuous transmission patterns are determined according to the first discontinuous transmission patterns and the first adjustment quantity. Based on the above scheme, the communication device may determine the first discontinuous transmission pattern as the reference pattern, and adjust the first discontinuous transmission pattern according to the corresponding first adjustment amount information to obtain a second discontinuous transmission pattern, where the second discontinuous transmission pattern is a discontinuous transmission pattern suitable for the communication device. In some implementations, the adjustment amount information for adjusting the corresponding discontinuous transmission pattern includes at least one parameter for adjusting the corresponding discontinuous transmission pattern, the at least one parameter including a start position, a duration, and a period. In some implementations, the method further includes receiving first indication information indicating the first adjustment amount information. Based on the scheme, the network equipment indicates which adjustment amount information is adopted by the communication equipment, so that the communication equipment can acquire an accurate discontinuous transmission pattern to perform data transmission, and the power consumption of the communication equipment is saved. In some implementations, the first indication information includes at least one of an identification of time domain resources or signals, an identification of frequency domain resources or signals, or an identification of spatial domain resources or locations. In some implementations, the identification of the time domain resource or signal includes at least one of a synchronization signal block index SSBindex, a channel state information reference signal index CSI-RS index, a resource group index, a logical channel identification LCID, and/or the identification of the frequency domain resource or signal includes at least one of a partial bandwidth identification BWP ID,
