Description

Method and device for transmitting perception data Technical Field The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for transmitting perceptual data. Background Along with the development of communication technology, technologies such as internet of things, artificial intelligence, big data and automation are reconstructing traditional industry, and intelligent applications such as smart city and automatic driving are induced. To better support these emerging applications, communication systems are evolving towards communication awareness Integration (ISAC). ISACs, also known as joint communication and awareness (joint communications AND SENSING, JCAS), may enable access network nodes and/or terminals to be provided with awareness capabilities, thereby enabling the communication system to provide awareness services to users. In the scenario that the communication system provides a perception service for a user, perception data, such as information of a position or a speed of a perception target at a certain moment, is transmitted among an access network node, a terminal and a core network element. But the reliability of data transmission in the above-described process is low, thereby affecting the quality of service of the perceived service. Disclosure of Invention The application provides a transmission method and a transmission device of perception data, which can check the perception data by taking a perception information block group as granularity, improve the reliability of the transmission of the perception data and further improve the service quality of perception service. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, a method of transmission of awareness data is provided, which may be performed by a first communication node. The first communication node may refer to the first communication node itself, or may refer to a processor, a circuit, a module, a logic node, software, a chip, or a chip system, etc. for implementing the method in the first communication node. The first communication node is an access network node, a terminal or a core network element, etc. The method comprises the steps of obtaining a first transmission block and sending the first transmission block and first indication information. The first transmission block comprises W perception information blocks, wherein W is an integer greater than or equal to 1, the W perception information blocks belong to M perception information block groups, and M is a positive integer less than or equal to W. The first indication information indicates M. The above-mentioned transmission of the first transport block and the first indication information may be understood as that the first communication node transmits the first transport block and the first indication information simultaneously, or transmits the first transport block and the first indication information at different times. In addition, the first transport block and the first indication information may be carried in the same message, or may be carried in different messages, which is not limited. Based on the method provided in the first aspect, the first communication node may send the first transport block and indicate the number of the perception information block groups included in the first transport block, so that the communication node (such as the second communication node) that receives the first transport block checks the first transport block with the perception information block groups as granularity, thereby improving the transmission reliability of the first transport block, and further improving the service quality of the perception service. In one possible implementation, the method further includes receiving the first information. Wherein the first information indicates a verification result of a perceptual information block group of the M perceptual information block groups. For example, the first information indicates a result of checking all or part of the groups of the M groups of the sense information blocks. Based on the possible implementation manner, the first communication node may obtain a verification result of the sensing information block group in the M sensing information block groups, so as to determine whether to retransmit the sensing data. In one possible implementation, the first information indicates that a first one of the M groups of perceptual information blocks fails to verify, and the method further comprises transmitting a second group of perceptual information blocks. The second perception information block group is retransmission information corresponding to the first perception information block group. Based on the possible implementation manner, in case that the verification of the first sensing information block group fails, the first communication node may send retransmission information of the
