Description

Communication method and device Technical Field The present application relates to the field of internet of things communications technologies, and in particular, to a communication method and apparatus. Background The current environment internet of things (Ambient Internet of Things, a-IoT) related issues do not define related configurations and flows for a-IoT devices (a-IoT devices) that cannot fully participate in the random access flow. The a-IoT devices may enter a sleep/power-off state due to insufficient energy in a round of random access and paging process, and the network side still configures time-frequency resources for the a-IoT devices, thereby resulting in time-frequency resource waste, or the network side does not know whether to perform a round of random access, resulting in low access efficiency of the a-IoT devices. Disclosure of Invention In view of the above, the present application provides a communication method and apparatus to solve at least some of the above problems, and the technical solution disclosed in the present application is as follows: In a first aspect, the application provides a communication method applied to network equipment, the method comprises the steps of sending a first message to an A-IoT device, wherein the first message is used for indicating the A-IoT device conforming to the reporting condition to report the position information of a first time-frequency resource of a second message, the second message carries a proprietary preamble, the proprietary preamble is used for associating with the appointed state of the A-IoT device, the proprietary preamble is different from the preamble of Msg1 in the random access process, and receiving a second message sent by the A-IoT device conforming to the reporting condition through the first time-frequency resource. For example, the specified status may be a remaining power shortage, a specific device type, a specific device priority, or the like. In this way, the method realizes that the A-IoT device reports the state of the A-IoT device when conforming to the reporting condition by configuring the special resource for reporting the specified state for the A-IoT device, so that the network device can timely acquire the A-IoT device in the specified state, and the efficiency of the network device in determining whether the A-IoT device in the specified state exists is improved. In a possible implementation manner of the first aspect, the first time-frequency resource includes a time-frequency resource. Therefore, the A-IoT device meeting the reporting condition reports the state of the device through the special first time-frequency resource, and does not occupy excessive resources, and the utilization rate of the resources is improved on the premise that the network device can know whether the A-IoT device with the specified state exists. In one possible implementation manner of the first aspect, the time-domain location and/or the frequency-domain location of the first time-frequency resource is different from the time-frequency resource for transmitting Msg1 in a random access procedure configured by the network device for the a-IoT device. Thus, the proprietary first time-frequency resource and the resource for transmitting the common Msg1 do not conflict with each other, and the success rate of receiving and transmitting the message is improved. In one possible implementation of the first aspect, the first message includes information for triggering the a-IoT device for random access. Thus, the A-IoT device can multiplex the Msg1 to report its own designated state, thereby improving the message utilization rate and further improving the resource utilization rate. In a possible implementation manner of the first aspect, the first message is further configured to indicate that the current round of messages is only used to count whether an a-IoT device that meets the reporting condition exists. In this way, the network device can inform the A-IoT device that the current round is only used for counting the specific A-IoT device through the first message, the step of random access is not needed to be executed, the message interaction efficiency of the current round is improved, and meanwhile, the success rate of the random access of the next round can also be improved. In one possible implementation manner of the first aspect, the proprietary preambles carried by all the second messages received by the network device through the first time-frequency resource are the same, the proprietary preambles are associated with the designated states of the a-IoT device, or the proprietary preambles carried by the plurality of second messages received by the network device through the first time-frequency resource are different, and the different proprietary preambles are associated with different designated states of the a-IoT device. In this way, the special lead code and the associated appointed state can be set according to th
