In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is provided.

In addition to communication capabilities, future mobile communication systems such as Beyond 5G (B5G) or 6G systems will also have perception capabilities. Perception capability refers to the ability of one or more devices with perception capabilities to perceive the direction, distance, speed and other information of target objects through the transmission and reception of wireless signals, or to detect, track, identify and image target objects, events or environments. In the future, with the deployment of small base stations with high-frequency band and large bandwidth capabilities such as millimeter waves and terahertz in 6G networks, the perception resolution will be significantly improved compared to centimeter waves, enabling 6G networks to provide more sophisticated perception services. Typical perception functions and application scenarios are shown in Table 1.

Table 1

Communication and perception integration (referred to as synaesthesia integration) is to achieve integrated design of communication and perception functions through spectrum sharing and hardware sharing in the same system. While transmitting information, the system can sense direction, distance, speed, etc. Information is collected to detect, track, and identify target objects or events. The communication system and the perception system complement each other to achieve overall performance improvements and bring a better service experience.

The integration of communication and radar is a typical application of communication and perception fusion. In the past, radar systems and communication systems were strictly distinguished due to different research objects and focus, and the two systems were studied separately in most scenarios. In fact, radar and communication systems are also typical ways of sending, acquiring, processing and exchanging information. There are many similarities in working principles, system architecture and frequency bands. The design of integrated communication and radar has great feasibility, which is mainly reflected in the following aspects: First, both communication systems and perception systems are based on electromagnetic wave theory, and use the transmission and reception of electromagnetic waves to complete the acquisition and transmission of information; secondly, both communication systems and perception systems have structures such as antennas, transmitters, receivers, and signal processors, and there is a great overlap in hardware resources; with the development of technology, the two have more and more overlaps in working frequency bands; in addition, there are similarities in key technologies such as signal modulation and reception detection, waveform design, etc. The integration of communication and radar systems can bring many advantages, such as saving costs, reducing size, reducing power consumption, improving spectrum efficiency, reducing mutual interference, etc., thereby improving the overall performance of the system.

According to the differences in the sending nodes and receiving nodes of the perception signals, there are six types of perception links. It should be noted that each perception link described below takes a sending node and a receiving node as an example. In the actual system, different perception links can be selected according to different perception requirements. Each perception link can have one or more sending nodes and receiving nodes, and the actual perception system can include multiple different perception links.

1) Base station self-transmitting and self-receiving sensing (base station echo sensing). In this mode, the base station sends a sensing signal and obtains the sensing result by receiving the echo of the sensing signal.

2) Air interface sensing between base stations: At this time, base station 2 receives the sensing signal sent by base station 1 and obtains the sensing result.

3) Uplink air interface perception. At this time, the base station receives the perception signal sent by the terminal (User Equipment, UE) and obtains the perception result.

4) Downlink air interface perception: At this time, the UE receives the perception signal sent by the base station and obtains the perception result.

5) Terminal autonomous transmission and reception sensing (terminal echo sensing): At this time, the UE sends a sensing signal and obtains a sensing result by receiving an echo of the sensing signal.

6) Sidelink perception between terminals. For example, UE 2 receives the perception signal sent by UE 1 and obtains the perception result.

It should be noted that in the above-mentioned perception methods, one perception signal sending node and one perception signal receiving node are used as examples. In actual systems, one or more different perception methods can be selected according to different perception use cases and perception requirements, and each perception method can have one or more sending nodes and receiving nodes. The perception target can be a person or a car, and assuming that neither the person nor the car carries or installs a signal receiving/transmitting device, the perception targets in actual scenarios will be richer.

The device according to claim 18, wherein at least two receiving antennas or at least two receiving channels in each of the receiving unit sets correspond to the same transceiver; or, at least two receiving antennas or at least two receiving channels in each of the receiving unit sets correspond to the same analog-to-digital converter; or, the polarization characteristics of at least two receiving antennas in each of the receiving unit sets are consistent; or, the feeder lengths of at least two receiving antennas in each of the receiving unit sets are consistent.
An information transmission device, applied to a second device, comprising:

A second acquisition module, used to acquire capability information sent by the first device, where the capability information is used to indicate that the first device includes at least one receiving unit set, each of which includes at least two receiving antennas or at least two receiving channels;

A third transceiver module is used to send a first message to the first device according to the capability information, wherein the first message is used to instruct the first device to send a first result of at least two target receiving units or to send a second result, wherein the at least two target receiving units are determined according to the at least one receiving unit set, wherein the first result is obtained by measuring the first signal, and the second result is obtained by performing a target operation on the first results corresponding to the at least two target receiving units; the target operation is a division operation or a conjugate multiplication operation; and the first signal includes at least one of a reference signal, a synchronization signal, a data signal and a dedicated signal.
A communication device comprises a processor and a memory, wherein the memory stores a program or instruction that can be run on the processor, and when the program or instruction is executed by the processor, the steps of the information transmission method as described in any one of claims 1 to 11 are implemented, or the steps of the information transmission method as described in any one of claims 12 to 17 are implemented.
A readable storage medium storing a program or instruction, wherein the program or instruction, when executed by a processor, implements the steps of the information transmission method according to any one of claims 1 to 11, or implements the steps of the information transmission method according to any one of claims 12 to 17.
