Description

Technical Field

[0001] This application relates to the field of communication technologies, and particularly to an information configuration method, device, and storage medium. Background Art

[0002] The cellular mobile system has a powerful network formation ability. Through the large-scale deployment of the cellular network and the interaction between the base station and the terminal, between the base stations, and between the base station and the core network, a mobile network system integrating communication and sensing is constructed. Network collaborative sensing based on the cellular system can make full use of the base station resources of the cellular system, which not only reduces the cost of communication and sensing integration but also realizes the network formation ability of sensing. By reasonably selecting the sensing base stations in the cellular system and sharing, supplementing, or merging the sensing data, the problem of signal mutual interference caused by too many nodes can be reduced while retaining the advantages of the cellular network. At the same time, network sensing can avoid occlusion through cooperation between base stations without upgrading hardware, further improving the sensing performance. However, the existing frequency-domain bandwidth of the sensing signal is limited by the bandwidth of the Demodulation Reference Signal (DMRS). Therefore, how to configure the frequency-domain bandwidth of the sensing signal is an urgent problem to be solved. Summary of the Invention

[0024] The embodiments of the present application will be described below with reference to the accompanying drawings. The present application will be described below in conjunction with the embodiments of the drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0025] The narrow - sense perception network refers to a system with capabilities such as target positioning (range finding, speed measurement, angle measurement), target imaging, target detection, target tracking, and target recognition; the broad - sense perception network refers to a system that can perceive all services, networks, users, terminals, as well as the attributes and states of environmental objects. In the mobile network with communication - sensing integration, the perception methods can be divided into active and passive. Passive perception means that the perceiver (network - side or terminal) perceives by acquiring the electromagnetic waves emitted by the target object (such as terahertz waves) or the electromagnetic waves reflected from outside the perceiver and the target object; active perception means that the perceiver (network - side or terminal) sends electromagnetic waves, and after being reflected by the target object, the perceiver receives the echo for perception. Among them, the node receiving the reflected wave is not necessarily the node sending the detection signal, that is, multiple nodes on the perception side can achieve active perception through some form of joint processing.

[0026] In network perception, wireless perception signal links can be classified into the following categories: (1) Base - station echo perception link: The base - station sends a perception signal and receives the echo signal; (2) Inter - base - station perception link: Base - station 2 receives the perception signal sent by Base - station 1; (3) Uplink perception link: The base - station receives the perception signal sent by the UE; (4) Downlink perception link: The UE receives the perception signal sent by the base - station; (5) Terminal echo perception link: The user equipment (UE) sends a perception signal and receives the echo signal; (6) Inter - terminal perception link: UE2 receives the perception signal sent by UE1. In an 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.

[0027] The integrated communication - sensing waveform design includes the following three design cases: integrated waveform design centered on communication, integrated waveform design centered on perception, and integrated waveform design with communication - sensing joint.

[0028] It should be noted that the node sending the perception signal in the embodiments of this application can be a base - station, UE, unmanned aerial vehicle, aircraft, or radar transmitting device. In the following embodiments, taking the base - station as the sending node of the perception signal, the methods described in the embodiments of this application are equally applicable to taking the UE, unmanned aerial vehicle, aircraft, radar transmitting device, etc. as the sending node.

[0029] In the embodiments of the present application, an existing reference signal can be used as the sensing signal, or a new sensing signal can be proposed. In one example, when using an existing reference signal as the sensing signal, the base station side can use the DMRS of at least two terminals as the sensing signal, and indicate through signaling that one of the terminals senses the target based on the DMRS of the at least two terminals and reports the sensing measurement result. In one example, when a new sensing signal is proposed, the multiplexing relationship between the new sensing signal and the existing New Radio (NR) reference signal (RS) is defined.

[0030] In one embodiment, Figure 1 is a flowchart of an information configuration method provided by an embodiment of the present application. This embodiment is applied to the case of flexibly configuring the frequency-domain bandwidth of the sensing signal. This embodiment can be executed by a first communication device. Exemplarily, the first communication device can be the terminal side or the base station side. When the first communication device is the terminal side, the corresponding second communication device is the base station side; when the first communication device is the base station side, the corresponding second communication device is the terminal side.

[0031] As Figure 1 shown, this embodiment includes: S110 - S120.

[0032] S110. Receive the sensing signal bandwidth configuration information sent by the second communication device.

[0033] S120. Configure the frequency-domain bandwidth of the corresponding sensing signal based on the sensing signal bandwidth configuration information.

[0034] In an embodiment, the first communication device may receive the sensing signal bandwidth configuration information sent by the second communication device and flexibly configure the frequency-domain bandwidth of the sensing signal based on the sensing signal bandwidth configuration information. In one embodiment, the sensing signal is the DMRS of at least two terminals to increase the frequency-domain bandwidth of the sensing signal, thereby improving the sensing resolution. In one embodiment, when the frequency-domain bandwidth of the sensing signal is not configured by radio signaling, the frequency-domain bandwidth of the sensing signal is equal to the DMRS frequency-domain bandwidth of the current first communication device. In one example, the current first communication device refers to the communication device that sends or receives the sensing signal. In one example, when using the existing DMRS as the sensing signal and the frequency-domain bandwidth of the sensing signal is not configured by radio signaling, if it is a downlink, the sensing target can be measured based on the DMRS of the physical downlink shared channel (PDSCH) corresponding to the current first communication device, and the DMRS frequency-domain bandwidth of the current first communication device is used as the frequency-domain bandwidth of the sensing signal; if it is an uplink, the sensing target can be measured based on the DMRS of the physical uplink shared channel (PUSCH) corresponding to the current first communication device, and the DMRS frequency-domain bandwidth of the current first communication device is used as the frequency-domain bandwidth of the sensing signal.

[0035] In one embodiment, when the frequency-domain bandwidth of the sensing signal is configured by radio signaling, the frequency-domain bandwidth of the sensing signal is configured in units of the DMRS frequency-domain bandwidth. In one example, when using the existing DMRS as the sensing signal and the frequency-domain bandwidth of the sensing signal is configured by radio signaling, the frequency-domain bandwidth of the sensing signal can be configured in units of the DMRS frequency-domain bandwidth, thereby solving the problem that the sensing signal bandwidth is limited by the DMRS bandwidth and improving the sensing resolution.

[0036] In one embodiment, configuring the frequency-domain bandwidth of the sensing signal in units of the DMRS frequency-domain bandwidth includes one of the following:

[0037] The frequency-domain bandwidth of the sensing signal is equal to this bandwidth unit; where this bandwidth unit is the DMRS frequency-domain bandwidth of the current first communication device;

[0038] The frequency-domain bandwidth of the sensing signal is equal to the first preset number of bandwidth units before this bandwidth unit and this bandwidth unit;

[0039] The frequency-domain bandwidth of the sensing signal is equal to the first preset number of bandwidth units after this bandwidth unit and this bandwidth unit;

[0040] The frequency domain bandwidth of the sensing signal is equal to the second preset number of bandwidth units before this bandwidth unit, this bandwidth unit, and the third preset number of bandwidth units after this bandwidth unit;

[0041] wherein, the first preset number, the second preset number, and the third preset number are all integers greater than 0.

[0042] In one embodiment, when configuring the frequency domain bandwidth of the sensing signal in units of the DMRS frequency domain bandwidth, it further includes: using radio resource control (RRC) signaling with a fourth preset number of bits to indicate the frequency domain bandwidth of the sensing signal. In one example, the fourth preset number is an integer greater than 0. For example, a fixed 1-bit RRC signaling can be used to indicate the frequency domain bandwidth of the sensing signal, or a fixed 2-bit RRC signaling's frequency domain bandwidth can be used, and there is no limitation in this regard.

[0043] In one embodiment, the frequency domain bandwidth of the sensing signal includes at least one of the following: this bandwidth unit; this bandwidth unit and at least one bandwidth unit before this bandwidth unit; this bandwidth unit and at least one bandwidth unit after this bandwidth unit. When using the existing DMRS as the sensing signal and using at least one-bit RRC signaling to indicate the frequency domain bandwidth of the sensing signal, at least one-bit RRC signaling can be used to indicate that this bandwidth unit is the frequency domain bandwidth of the sensing signal, or at least one-bit RRC signaling can be used to indicate the total bandwidth of this bandwidth unit and at least one bandwidth unit before this bandwidth unit as the frequency domain bandwidth of the sensing signal, or at least one-bit RRC signaling can be used to indicate the total bandwidth of this bandwidth unit and at least one bandwidth unit after this bandwidth unit as the frequency domain bandwidth of the sensing signal, or at least one-bit RRC signaling can be used to indicate the total bandwidth of this bandwidth unit, at least one bandwidth unit after this bandwidth unit, and at least one bandwidth unit before this bandwidth unit as the frequency domain bandwidth of the sensing signal.

[0044] In one embodiment, the sensing signal is used as a reference signal for the quasi co-location (QCL) information in the transmission configuration indicator (TCI) state.

[0045] In one embodiment, the reference signal types in the TCI state at least include: the Sensing Target Reference Signal (STRS). In one example, STRS can be added to the selection types of reference signals in the TCI state. It can also be understood that a new reference signal is defined in the TCI state for sensing the target, which can be called STRS or the Sensing Function Reference Signal (SFRS).

[0046] In one embodiment, the RRC signaling is used to indicate the starting resource block and the total bandwidth length of the sensing signal. In one example, the starting resource block is used to represent the starting Physical Resource Block (PRB) of the frequency-domain resource corresponding to the newly defined sensing signal relative to the common resource block 0; the total bandwidth length is used to represent the number of physical resource blocks occupied by the frequency-domain resource corresponding to the newly defined sensing signal.

[0047] In one embodiment, the QCL types between the STRS and another sensing target at least include one of the following: Type E;

[0048] Among them, the Type E at least includes one of the following: Doppler frequency shift, average delay, and average angle; Doppler frequency shift, average delay, and average angle; average angle; average Radar Cross section (RCS). In one example, the QCL relationship between the STRS and another sensing target signal can be newly defined. For example, the QCL types between the STRS and another sensing target at least include one of the following: Type E; among them, the Type E at least includes one of the following: Doppler shift, average delay, and average angle; Doppler frequency shift, average delay, and average angle; average angle; average RCS.

[0049] In one embodiment, Figure 2 is the flowchart of another information configuration method provided by the embodiments of the present application. This embodiment is applied to the case of dynamically configuring the frequency-domain bandwidth of the sensing signal. This embodiment can be executed by the second communication device. As Figure 2 shown, this embodiment includes: S210.

[0050] S210. Send the sensing signal bandwidth configuration information to the first communication device, so that the first communication device configures the frequency-domain bandwidth of the corresponding sensing signal based on the sensing signal bandwidth configuration information.

[0051] In one embodiment, when the frequency-domain bandwidth of the sensing signal is not configured by radio signaling, the frequency-domain bandwidth of the sensing signal is equal to the DMRS frequency-domain bandwidth of the current first communication device.

[0052] In one embodiment, when the frequency-domain bandwidth of the sensing signal is configured by radio signaling, the frequency-domain bandwidth of the sensing signal is configured in units of the DMRS frequency-domain bandwidth.

[0053] In one embodiment, configuring the frequency-domain bandwidth of the sensing signal in units of the DMRS frequency-domain bandwidth includes one of the following:

[0054] The frequency-domain bandwidth of the sensing signal is equal to this bandwidth unit; wherein, this bandwidth unit is the DMRS frequency-domain bandwidth of the current first communication device;

[0055] The frequency-domain bandwidth of the sensing signal is equal to the first preset number of bandwidth units before this bandwidth unit and this bandwidth unit;

[0056] The frequency-domain bandwidth of the sensing signal is equal to the first preset number of bandwidth units after this bandwidth unit and this bandwidth unit;

[0057] The frequency-domain bandwidth of the sensing signal is equal to the second preset number of bandwidth units before this bandwidth unit, this bandwidth unit, and the third preset number of bandwidth units after this bandwidth unit;

[0058] Wherein, the first preset number, the second preset number, and the third preset number are all integers greater than 0.

[0059] In one embodiment, configuring the frequency-domain bandwidth of the sensing signal in units of the DMRS frequency-domain bandwidth further includes: using RRC signaling with a fourth preset number of bits to indicate the frequency-domain bandwidth of the sensing signal.

[0060] In one embodiment, the frequency-domain bandwidth of the sensing signal at least includes one of the following: this bandwidth unit; this bandwidth unit and at least one bandwidth unit before this bandwidth unit; this bandwidth unit and at least one bandwidth unit after this bandwidth unit.

[0061] In one embodiment, the sensing signal is used as a reference signal for QCL information in the TCI state.

[0062] In one embodiment, the reference signal type in the TCI state at least includes: STRS.

[0063] In one embodiment, RRC signaling is used to indicate the starting resource block and the total bandwidth length of the sensing signal.

[0064] In one embodiment, the QCL type between the STRS and another sensing target at least includes one of the following: TypeE type;

[0065] Among them, the TypeE type includes at least one of the following: Doppler frequency shift, average time delay, and average angle; Doppler frequency shift, average time delay, and average angle; average angle; average radar cross section RCS.

[0066] It should be noted that for the explanations of parameters such as the sensing signal, the sensing signal bandwidth configuration information, the frequency-domain bandwidth of the sensing signal, and the STRS involved in the information configuration method applied to the second communication device, refer to the descriptions of the corresponding parameters in the above information configuration method applied to the first communication device, which will not be elaborated here.

[0067] In an embodiment, taking the existing reference signal as the sensing signal as an example, the configuration process of the frequency-domain bandwidth of the sensing signal is described. Among them, the current first communication device is denoted as this UE, and the second communication device is denoted as the base station. It is assumed that the first preset quantity, the second preset quantity, and the third preset quantity are all 1, and the fourth preset quantity K is 2.

[0068] Generally speaking, the synchronization signal and the physical broadcast channel block (SSB) only occupy a part of the frequency-domain bandwidth. The channel state information reference signal (CSI-RS) and the phase tracking reference signal (PTRS) are usually much sparser in the frequency domain than the DMRS (that is, the frequency-domain density of the DMRS is relatively higher), and the density of the DMRS in the time domain is flexibly configurable. Therefore, the DMRS is more suitable for use as the sensing signal than the CSI-RS and the PTRS. However, the frequency-domain bandwidth of the DMRS is the same as the bandwidth of the scheduled PDSCH / PUSCH. In the case of scheduling the PDSCH / PUSCH with a small bandwidth, the DMRS of the UE corresponding to the small bandwidth scheduling at this time is not suitable for use as the sensing signal.

[0069] In view of this, the embodiment of the present application can use the DMRS of at least two UEs as the sensing signal, which can increase the frequency-domain bandwidth of the sensing signal.

[0070] Figure 3 It is a schematic diagram of the configuration of the DMRS of different UEs provided by the embodiment of the present application. As Figure 3As shown in (a) thereof, if the PDSCHs of UE1 and UE2 are scheduled in a frequency division manner and the source reference signals of QCL are the same (i.e., the base station uses the same transmission beam to transmit to UE1 and UE2), the base station can use the UE1 DMRS and UE2 DMRS as sensing signals, and indicate to UE1 or UE2 through radio signaling to sense the target based on the UE1 DMRS and UE2 DMRS and report the sensing measurement results.

[0071] The content indicated by the radio signaling includes:

[0072] First, if the frequency-domain RB position of the sensing signal is not configured through RRC signaling, the target can be sensed based on the PDSCH DMRS measurement of this UE, and the frequency-domain bandwidth of the sensing signal is equal to the DMRS bandwidth of this UE;

[0073] Second, if the frequency-domain RB position of the sensing signal is configured through RRC signaling, it can be configured in units of the DMRS frequency-domain bandwidth. For example,

[0074] If the bitmap signaling is 00100, it means that the frequency-domain bandwidth of the sensing signal is equal to the DMRS bandwidth of this UE (denoted as this bandwidth unit);

[0075] If the bitmap signaling is 01100, it means that the frequency-domain bandwidth of the sensing signal is equal to the previous 1 bandwidth unit + this bandwidth unit;

[0076] If the bitmap signaling is 01110, it means that the frequency-domain bandwidth of the sensing signal is equal to the previous 1 bandwidth unit + this bandwidth unit + the next 1 bandwidth unit;

[0077] Alternatively, use fixed K-bit RRC signaling. For example, taking 2-bit signaling as an example:

[0078] 2-bit signaling Meaning 00 This bandwidth unit 01 This bandwidth unit + the next 1 bandwidth unit 10 This bandwidth unit + the next 2 bandwidth units 11 This bandwidth unit + the next 3 bandwidth units

[0079] As Figure 3 As shown in (b) thereof, if the DMRSs of UE1 and UE2 are not in the same time domain symbol, UE1 and UE2 respectively sense the target and report the measurement results.

[0080] For the uplink, the SRS is very flexible in time-domain and frequency-domain configurations, and the ZC sequence can be used as the reference signal sequence, which has good autocorrelation characteristics and low PAPR and is suitable for use as the uplink sensing signal.

[0081] In one embodiment, taking the definition of a new sensing signal as an example, the multiplexing relationship between the new sensing signal and the existing NR RS is described.

[0082] Generally speaking, the existing QCL types in NR include QCL-TypeA, QCL-TypeB, QCL-TypeC, and QCL-TypeD.

[0083] QCL-TypeA: (Doppler shift, Doppler spread, average delay, delay spread). Except for the Spatial-Rx parameter, other large-scale parameters are the same. It provides a relatively comprehensive description of the target channel. The UE can obtain a comprehensive description of the DM-RS characteristics and is mostly used for channel demodulation.

[0084] QCL-TypeB: (Doppler shift, Doppler spread). It can inherit the Doppler frequency shift and Doppler spread from the reference signal. For low-frequency scenarios, it is divided into two cases: one is when using a narrow-beam reference signal, the wide-beam reference signal is used as the QCL reference; the other is that the time domain of the target reference signal is insufficient, but the frequency domain density is sufficient.

[0085] QCL-TypeC: (Average delay, Doppler shift). It is only for the case where the SSB is used as the QCL reference. Since the resources and density occupied by the SSB are limited, only some relatively rough large-scale information can be obtained from the SSB, that is, inherit the Doppler frequency shift and average delay characteristics from the reference signal, while other large-scale parameters can be obtained from the target reference signal itself.

[0086] QCL-TypeD: (Spatial Rx parameter). It can inherit the beam information from the reference signal and can be used for beam training.

[0087] In this embodiment, a new reference signal is defined for sensing the target, which can be called STRS or SFRS. Taking STRS as an example below, STRS can be multiplexed with DMRS in a frequency-division manner, or multiplexed with data in a time-division manner, and uses a Linear Frequency Modulated Signal (LFM) sequence, or a Maximum-Length Sequence (m-sequence), or a Zadoff–Chu (ZC) sequence or a gold sequence.

[0088] STRS can be used as the source reference signal for the existing QCL types. For example, the selection type of the reference signal can be added as STRS STRS-Index in the IE TCI-State.

[0089] The base station and the UE can be pre - defined that if the reference signal configured in the QCL - Info is STRS and the QCL - Type is typeA, then STRS is used as DMRS; if the QCL - Type is typeD, then the PDSCH is received using the reception beam of STRS, or the PUSCH is transmitted using a transmission beam that is the same as or similar to the reception beam of STRS.

[0090] The starting resource block (Resource Block, RB) and the total bandwidth length of the sensing signal can be represented by the following IESTRS - Frequency Occupation:

[0091] Among them, two parameters can be added to the STRS - Frequency Occupation: the starting resource block (denoted as startingRB) and the total bandwidth length (denoted as nrofRBs); where startingRB is the starting PRB of the STRS or STRS resource relative to the common resource block 0 (CRB#0); nrofRBs is the number of PRBs spanned or occupied by the STRS or STRS resource.

[0092] In addition, the QCL relationship between the sensing target signal (i.e., STRS) and another sensing target signal (which can also be simply referred to as the sensing target) can be newly defined, such as QCL typeE:

[0093] -'typeA': {Doppler shift, Doppler spread, average delay, delay spread};

[0094] -'typeB': {Doppler shift, Doppler spread};

[0095] -'typeC': {Doppler shift, average delay};

[0096] -'typeD': {Spatial Rx parameter};

[0097] -'typeE': {Doppler shift, average delay, angle};

[0098] Or,

[0099] -'typeE': {Doppler shift, average delay, average angle};

[0100] Or,

[0101] -'typeE': {average angle};

[0102] Or,

[0103] -'typeE': {average RCS};

[0104] Wherein, RCS is the Radar Cross section.
