Description

Communication method and related device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and a related device. Background The wireless communication may be transmission communication between two or more communication devices without propagation via a conductor or cable. Typically, the two or more communication devices comprise a network device and a terminal device, or the two or more communication devices comprise different terminal devices. In a communication system, communication services can be obtained by means of signal transmission between different communication devices. However, how to improve the signal transmission performance is a technical problem to be solved. Disclosure of Invention The application provides a communication method and related equipment, which are used for improving signal transmission performance. The first aspect of the present application provides a communication method applied to a first communication apparatus, for example, the first communication apparatus may be a communication device (such as a terminal device or a network device), or the first communication apparatus may be a part of a component in the communication device (such as a processor or a circuit or a chip system responsible for a communication function), or the first communication apparatus may also be a logic module or software capable of implementing all or part of the function of the communication device. In the method, a first communication device determines a first signal, the first communication device sends the first signal, and the first signal is carried by a first resource, wherein the first resource comprises N time domain resources, a signal carried by an nth time domain resource in the N time domain resources is obtained through processing an nth first orthogonal sequence in N first orthogonal sequences, N is an integer greater than 1, and the value of N is an integer from 1 to N. Based on the above-mentioned scheme, the first signal sent by the first communication device is carried on the first resource, and, among the N time domain resources included in the first resource, the signal carried by the nth time domain resource is obtained by processing the nth first orthogonal sequence in the N first orthogonal sequences. In other words, the signals carried by the N time domain resources are respectively obtained by processing the changed (or hopped) orthogonal sequences in the N first orthogonal sequences. In this way, the signals sent by different communication devices on the first resource by using different orthogonal sequences may be mutually orthogonal, that is, the signal receiver can distinguish the signals sent by different communication devices based on the orthogonal sequences, so that different communication devices can multiplex the same resource for signal transmission, and the resource utilization rate can be improved, so as to improve the signal transmission performance. In addition, on the N time domain resources, the N first orthogonal sequences can hop on different time domain resources, compared with the implementation process that different communication devices use orthogonal sequences which remain unchanged (i.e. do not hop) on different time domain resources and are likely to generate mutual interference, because the first orthogonal sequences used by different time domain resources on the N time domain resources are hopped, asynchronous transmission interference randomization can be realized through the hopped orthogonal sequences, so as to reduce interference among different communication devices, and further improve signal transmission performance. It should be appreciated that N time domain resources are associated with N first orthogonal sequences. For example, in the above scheme, the association is expressed as that the signal carried by the nth time domain resource in the N time domain resources is processed by the nth first orthogonal sequence in the N first orthogonal sequences, or the association may be understood that the first orthogonal sequences corresponding to different time domain resources in the N time domain resources are changed (or hopped). In other words, the association may be expressed as that N first orthogonal sequences corresponding to N time domain resources are varied (or hopped), that any two adjacent first orthogonal sequences of N first orthogonal sequences corresponding to N time domain resources are varied (or hopped), or that any two adjacent first orthogonal sequences corresponding to N time domain resources are varied (or hopped). Alternatively, the N first orthogonal sequences may be implemented in various ways. For example, at least two first orthogonal sequences of the N first orthogonal sequences are different. The signals carried by the N time domain resources are respectively obtained by processing the changed (or hopped) orthogonal sequence
