Detailed Description

The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are derived by a person skilled in the art based on the embodiments of the application, fall within the scope of protection of the application.

The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the "first" and "second" distinguishing between objects generally are not limited in number to the extent that the first object may, for example, be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/" generally means a relationship in which the associated object is an "or" before and after.

It should be noted that the techniques described in the embodiments of the present application are not limited to long term evolution (Long Term Evolution, LTE)/LTE evolution (LTE-Advanced, LTE-a) systems, but may also be used in other wireless communication systems, such as code division multiple access (Code Division Multiple Access, CDMA), time division multiple access (Time Division Multiple Access, TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), orthogonal frequency division multiple access (Orthogonal Frequency Division Multiple Access, OFDMA), single carrier frequency division multiple access (Single-carrier Frequency Division Multiple Access, SC-FDMA), and other systems. The terms "system" and "network" in embodiments of the application are often used interchangeably, and the techniques described may be used for both the above-mentioned systems and radio technologies, as well as other systems and radio technologies. The following description describes a New Radio (NR) system for exemplary purposes and NR terminology is used in much of the following description, but these techniques may also be applied to applications other than NR system applications, such as 6 th Generation (6G) communication systems.

In order to facilitate understanding of the embodiments of the present application, the following technical points are first described:

1. communication perception integration/communication perception integration.

Future Beyond 5 Generation (Beyond 5th Generation,B5G) and 6 th Generation (6G) wireless communication systems are expected to provide various high-precision sensing services, such as indoor positioning of robot navigation, wi-Fi sensing of smart home and radar sensing of automatic driving automobiles. The sensing and communication systems are typically designed separately and occupy different frequency bands. Then, due to the widespread deployment of millimeter wave and large-scale Multiple-Input Multiple-Output (MIMO) technologies, communication signals in future wireless communication systems tend to have high resolution in both the time domain and the angle domain, which makes it possible to realize high-precision sensing with the communication signals. It is therefore desirable to jointly design the sensing and communication systems so that they can share the same frequency band and hardware to improve frequency efficiency and reduce hardware costs. This has prompted research into Communication and awareness Integration (ISAC). ISACs will become a key technology in future wireless communication systems to support many important application scenarios. For example, in future networks of autonomous vehicles, the autonomous vehicle will obtain a large amount of information from the network, including ultra-high resolution maps and near real-time information, to navigate and avoid upcoming traffic jams. In the same case, radar sensors in autonomous vehicles should be able to provide powerful, high resolution obstacle detection functions, with resolutions in the order of centimeters. ISAC techniques for autonomous vehicles offer the possibility of high data rate communication and high resolution obstacle detection using the same hardware and spectrum resources. Other applications of ISACs include Wi-Fi based indoor positioning and activity recognition, communication and sensing of unmanned aircraft, extended Reality (XR), radar and communication integration, and the like. Each application has different requirements, limitations and regulatory issues. ISACs have attracted tremendous research interest and attention in both academia and industry. For example, there have been more and more recent academic publications on ISACs, ranging from transceiver architecture design, ISAC waveform design, joint coding design, time-frequency-space signal processing, to experimental performance delay, prototyping, and field testing.

The ISAC obtains the integrated low-cost implementation of the communication and perception dual functions in a mode of sharing hardware equipment and defining functions by software, and is mainly characterized in that: the structure is unified and simplified, the functions are reconfigurable and expandable, and the efficiency is improved and the cost is reduced. The advantages of communication perception integration mainly have three aspects: firstly, the equipment cost is reduced, the size is reduced, secondly, the spectrum utilization rate is improved, and thirdly, the system performance is improved.

The development of ISACs is generally divided into four phases: coexistence, co-operation, co-design, and co-collaboration.

(1) Coexistence: communication and perception are two mutually separated systems, the two systems can mutually interfere, and the main method for solving the interference is as follows: distance isolation, frequency band isolation, time division operation, MIMO technology, precoding, etc.

(2) And (3) common operation: the common hardware platform is shared by communication and perception, common performance is improved by utilizing common information, and the power distribution between the common hardware platform and the common hardware platform has great influence on system performance, and the main problems are as follows: low signal-to-noise ratio, mutual interference, low throughput.

(3) And (3) co-designing: communication and sensing become a complete joint system, including joint signal design, waveform design, code design, etc., with chirped waveforms, spread spectrum waveforms, etc. in the early stage, and later focused on orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) waveforms, MIMO techniques, etc.

(4) Co-operation: and a plurality of communication perception integrated nodes cooperate with each other to realize a public target. For example, radar detection information is shared through communication data transmission, and typical scenarios are driving assistance systems, radar-assisted communication, and the like.

At present, a scene of integration of typical communication perception, which is expected to be realized by technical upgrading according to a 5G communication system architecture, such as

Table 1 shows the results.

2. Configuration method for sensing signal

The configuration method of the communication reference signal is described herein by taking the configuration method of the Channel-State-Information REFERENCE SIGNAL, CSI-RS in the New air interface (NR) as an example. Although the configuration of other reference signals and the configuration of CSI-RS are different, the method of configuration is basically the same, and can be imitated by the description in the background art-2, which is not described here.

It should be noted that, when configuring CSI-RS, the network side must consider the Pre-configured (Pre-configuration) system signal and the Pre-reserved system channel in the NR system, where the SSB includes a primary synchronization signal (Primary Synchronization Signal, PSS), a secondary synchronization signal (Secondary Synchronization Signal, SSS), a physical broadcast channel (Physical broadcast channel, PBCH), and a PBCH Demodulation reference signal (Demodulation REFERENCE SIGNAL, DM-RS). The configured reference signal resources cannot coincide with the resources used by these system signals and system channels.

The CSI-RS signal is configured by an information element (Information Elements, IE) of a radio resource control (Radio Resource Control, RRC), i.e. CSI measurement configuration (CSI-MeasConfig). The CSI-MeasConfig includes information element Non-Zero Power (NZP) -CSI-RS-resources (Resource), NZP-CSI-RS-Resource set (Resource set), CSI Resource configuration (CSI-ResourceConfig).

As shown in fig. 1, the information Element NZP-CSI-RS-Resource is a physical Resource used to configure CSI-RS, that is, a CSI-RS signal and a Resource Element (RE) Mapping relation (Resource Mapping) allocated in the OFDM time-frequency domain. The resource pool of the physical resource configuration of CSI-RS may have 192 different kinds of physical resources at the highest, i.e. m=192. Each CSI-RS physical resource has its own corresponding Identity (ID).

The configured CSI-RS physical resources form a CSI-RS Resource Set (namely Resource Set) through an information element CSI-RS-Resource Set. The total number of resource sets can reach 64 at most, namely n=64, and each CSI-RS resource set has its own corresponding ID. Each CSI-RS resource set is selected from a CSI-RS physical resource pool, and each resource set may have at most 64 different kinds of physical resources, i.e., m_n=64, where N is an index of the resource set, and 0N is equal to or less than N.

The information element CSI-ResourceConfig is used to configure CSI-RS resource allocation sets, and the number of CSI-RS resource allocation sets is l_1, and the total number of other resource allocation sets (i.e., SSB resource allocation set l_2, im resource allocation set l_3) can reach 112 at the highest, i.e., l_1+l_2+l_3=l+.112. The CSI-RS resource allocation sets are selected from the CSI-RS resource sets, and each CSI-RS resource allocation set can have 16 different types of CSI-RS resource sets at most, namely N_l=16, wherein L is more than or equal to 0 and less than or equal to L_1. Each CSI-RS resource allocation set has its own corresponding ID. In addition, CSI-ResourceConfig specifies which CSI-ResourceConfig to use for measurements. The measurement type and corresponding CSI-ResourceConfig ID are done through a mapping table.

The terminal according to the present application may be a Mobile phone, a tablet PC (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side device called a notebook, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a palm PC, a netbook, an ultra-Mobile Personal Computer (ultra-Mobile Personal Computer, UMPC), a Mobile internet appliance (Mobile INTERNET DEVICE, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a robot, a wearable device (Wearable Device), a vehicle-mounted device (VUE), a pedestrian terminal (PUE), a smart home (home device with a wireless communication function such as a refrigerator, a television, a washing machine, a furniture, etc.), a game machine, a Personal Computer (Personal Computer, PC), a teller machine, a self-service machine, etc., the wearable device including: intelligent watches, intelligent bracelets, intelligent headphones, intelligent glasses, intelligent jewelry (intelligent bracelets, intelligent rings, intelligent necklaces, intelligent bracelets, intelligent footchains, etc.), intelligent bracelets, intelligent clothing, game machines, etc. It should be noted that, the embodiment of the present application is not limited to a specific type of terminal.
