Description

Communication method and device Technical Field The present application relates to the field of communications technologies, and in particular, to a communications method and apparatus. Background In a communication system, since uplink and downlink channels do not have reciprocity, a network device generally transmits downlink reference signals to a terminal device, the terminal device performs channel measurement and interference measurement to estimate downlink Channel State Information (CSI) according to the received downlink reference signals, and the terminal device generates a CSI report (report) according to a predefined protocol manner or a network device configuration manner and feeds back to the network device. The number of CSI processing units (CSI processing unit, CPU) that the terminal device needs to occupy for different CSI reports is specified in the existing protocol, and since the terminal device counts the CPU for different CSI reports separately, this means that when different CSI reports that the terminal device needs to calculate relate to the same or repeated measurement processes, the terminal device can process these measurement processes independently, which further causes waste of CPU resources. Disclosure of Invention The application provides a communication method and a communication device, which can reduce the waste of CPU resources of a channel state information processing unit and improve the CPU utilization rate. In a first aspect, an embodiment of the present application provides a communication method, where the method may be applied to a terminal side device, where the terminal side device may be a terminal device, or may be a component (for example, a processor, a chip, a circuit, or a chip system) in the terminal device, or may also be a logic module or software capable of implementing all or part of functions of the terminal device, where the method includes obtaining a first CPU occupancy rule of a first channel state information processing unit, where the first CPU occupancy rule is a CPU occupancy rule when processing at least two CSI reports of channel state information includes a first processing part, and determining, according to the first CPU occupancy rule, a CPU occupancy number of at least one CSI report in the at least two CSI reports. Optionally, the first processing portion is a repeated processing portion, a repeated measuring portion, a repeated calculating portion, the same processing portion, the same measuring portion, or the same calculating portion. Optionally, the CPU occupation number of the at least one CSI report does not include the CPU occupation number corresponding to the first processing portion, or the CPU occupation number corresponding to the first processing portion is 0. In the above method, since the terminal device counts CPUs separately for different CSI reports, this means that when different CSI reports that the terminal device needs to calculate relate to the same or repeated measurement processes, the terminal device processes these measurement processes independently, which results in that when at least two CSI reports each include the first processing portion, when determining the CPU occupancy numbers of the at least two CSI reports, the CPU occupancy numbers of the at least two CSI reports each include the CPU occupancy number corresponding to the first processing portion, that is, the CPU occupancy number corresponding to the one processing portion is counted multiple times, thereby causing waste of CPU resources. By the method, the fact that at least two CSI reports comprise the first processing part is considered, namely, when the fact that the at least two CSI reports have the same or repeated measuring process is considered, the CPU occupation number corresponding to the first processing part only needs to be counted once, the CPU occupation number corresponding to the first processing part in at least one of the at least two CSI reports is not counted, waste of CPU resources of a channel state information processing unit can be reduced, and the CPU utilization rate is improved. In one possible implementation, the first CPU occupation rule includes that when the processes of the at least two CSI reports each include a first processing portion, the first processing portion of at least one of the at least two CSI reports does not occupy a CPU. In the method, the waste of CPU resources can be reduced and the CPU utilization rate can be improved by the mode. In yet another possible implementation, the first CPU occupation rules include that the at least two CSI reports include a first CSI report and a second CSI report, the first CSI report having a higher priority than the second CSI report, the first processing portion of the second CSI report not occupying the CPU. In the method, compared with the prior art, the CPU occupation number of the first CSI report comprises the CPU occupation number corresponding to the fir
