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 the downlink scheduling process of the communication system, the network device can allocate transmission resources for the terminal device according to the transmission requirements of data such as services, control signaling, feedback reports and the like. The transmission resources allocated by the network device to the terminal device may be indicated to the terminal device by downlink control information (Downlink Control Information, DCI) carried by a physical downlink control channel (Physical Downlink Control Channel, PDCCH). Thus, the terminal device needs to search the PDCCH to know which way the network device will transmit data to it on which time-frequency resources later. Since the terminal device does not know when the network device schedules resources to it, the terminal device needs to search for the PDCCH continuously, i.e. blindly, within the agreed resource range. If the terminal device continuously blindly detects the PDCCH, a larger power consumption overhead will be caused. Disclosure of Invention The embodiment of the application discloses a communication method and a communication device, which can reduce the power consumption overhead of terminal equipment in the downlink scheduling process of a communication system. In a first aspect, an embodiment of the present application discloses a communication method, which may be performed by a terminal device. The terminal device may be a terminal device, a component (such as a chip, a chip system, etc.) configured in the terminal device, or a logic module or software capable of implementing all or part of the functions in the terminal device, which is not limited in the present application. Illustratively, the method includes: the method comprises the steps of sending first information, receiving second information, determining the second information based on the first information, and monitoring the PDCCH based on the second information, wherein the first information comprises information for indicating at least one first template, the first template is used for indicating the monitoring position of the recommended physical downlink control channel PDCCH. In the scheme, after the terminal equipment sends first information to the network equipment, the first information comprises one or more templates recommended by the terminal equipment to monitor the position of the PDCCH. After the network device receives the first information, the second information may be determined based on the first information. The second information includes a position indicating that the terminal device monitors the PDCCH. After receiving the second information, the terminal device may monitor the PDCCH based on the second information. It can be understood that the template of the position of the terminal device recommended in the first information for monitoring the PDCCH is a template which can save power consumption to a certain extent for the terminal device and basically meets the service delay requirement. The network device can enable the position of the terminal device for monitoring the PDCCH to meet the service requirement more based on the second information determined by the first information. Therefore, the terminal equipment monitors the position of the PDCCH by aligning with the network equipment, so that the terminal equipment can save more energy while meeting the service requirement in the downlink scheduling process. With reference to the first aspect, in a possible implementation manner, the first information further includes at least one of confidence, occurrence ratio and occurrence probability of at least one first template. In the scheme, by including other information of the template, such as one or more of confidence level, occurrence ratio and occurrence probability, on one hand, the flexibility of the network equipment for determining the second information is improved, and on the other hand, the network equipment is convenient to determine the second information which meets the service requirement better and can enable the terminal equipment to save more energy. With reference to the first aspect, in one possible implementation manner, the first template includes a plurality of time units, and the first information further includes information of a predicted or generalized scheduling data amount of each time unit in the plurality of time units. In the scheme, the first template can comprise a plurality of time units, the first information sent to the network equipment by the terminal equipment comprises information of the first template, the information of the first template comprising the first information also comprises information of scheduling data quantity predicted or generalized by each time unit in the plurality of time units,
