Description

Information configuration method, device and storage medium Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information configuration method, device, and storage medium. Background Art

[0002] Cellular mobile systems possess powerful networking capabilities. Through the large-scale deployment of cellular networks and the interaction between base stations and terminals, base stations and base stations, and base stations and core networks, a mobile network system with integrated perception can be constructed. Network collaborative perception based on the cellular system can fully utilize the base station resources of the cellular system, reducing the cost of integrated communication and perception while realizing the networking capabilities of perception. By rationally selecting perception base stations in the cellular system and sharing, supplementing, or merging perception data, the problem of signal interference caused by too many nodes can be reduced while retaining the advantages of the cellular network. At the same time, network perception can avoid obstructions through collaboration between base stations without upgrading hardware, further improving perception performance. However, the frequency domain bandwidth of existing perception signals is limited by the bandwidth of the Demodulation Reference Signal (DMRS). Therefore, how to configure the frequency domain bandwidth of the perception signal is an urgent problem to be solved.

[0025] The following describes the embodiments of the present application in conjunction with the accompanying drawings. The following describes the present application in conjunction with the accompanying drawings. The examples are only used to explain the present application and are not used to limit the scope of the present application.

[0026] In a narrow sense, a perception network refers to a system capable of target positioning (ranging, speed, and angle measurement), target imaging, target detection, target tracking, and target identification. In a broad sense, a perception network refers to a system capable of perceiving the attributes and states of all services, networks, users, and terminals, as well as environmental objects. In mobile networks with interawareness, perception can be categorized as active or passive. Passive perception involves the perceiver (on the network or on the terminal) sensing electromagnetic waves emitted by the target object (such as terahertz waves) or reflected electromagnetic waves from outside the perceiver and target object. Active perception involves the perceiver (on the network or on the terminal) transmitting electromagnetic waves, which then reflect off the target object and receive the echo for perception. The node receiving the reflected wave is not necessarily the same node that sent the detection signal; that is, multiple sensing nodes can achieve active perception through some form of joint processing.

[0027] In network perception, wireless perception signal links can be divided into the following categories: (1) Base station echo perception link: the base station sends a perception signal and receives an echo signal; (2) Inter-base station perception link: base station 2 receives a perception signal sent by base station 1; (3) Uplink perception link: the base station receives a perception signal sent by the UE; (4) Downlink perception link: the UE receives a perception signal sent by the base station; (5) Terminal echo perception link: the user equipment (UE) sends a perception signal and receives an echo signal; (6) Inter-terminal perception link: UE2 receives a perception signal sent by UE1. In actual systems, different perception links can be selected according to different perception requirements. Each perception link can have one or more sending nodes and one or more receiving nodes, and an actual perception system can include multiple different perception links.

[0028] Synaesthesia integrated waveform design includes the following three design situations: communication-centered integrated waveform design, perception-centered integrated waveform design, and synaesthesia-combined integrated waveform design.

[0029] It should be noted that the node sending the perception signal in the embodiments of the present application may be a base station, UE, drone, aircraft, or radar transmitting device. In the following embodiments, a base station is used as the transmitting node of the perception signal. The methods described in the embodiments of the present application are also applicable to UE, drone, aircraft, or radar transmitting device as the transmitting node.

[0030] In an embodiment of the present application, an existing reference signal may be used as a perception signal, or a new perception signal may be proposed. In one example, when an existing reference signal is used as a perception signal, the base station side may use the DMRS of at least two terminals as the perception signal, and instruct one of the terminals through signaling to perceive a target based on the DMRS of the at least two terminals, and report the perception measurement results. In one example, when a new perception signal is proposed, the multiplexing relationship between the new perception signal and the existing New Radio (NR) Reference Signal (RS) is defined.

[0031] 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 perception signal. This embodiment can be performed by a first communication device. For example, the first communication device can be on the terminal side or on the base station side. When the first communication device is on the terminal side, the corresponding second communication device is on the base station side; when the first communication device is on the base station side, the corresponding second communication device is on the terminal side.

[0032] As shown in FIG1 , this embodiment includes: S110 - S120 .

[0033] S110: Receive perception signal bandwidth configuration information sent by a second communication device.

[0034] S120: Configure a frequency domain bandwidth corresponding to the perception signal based on the perception signal bandwidth configuration information.

[0035] In an embodiment, a first communications device may receive perception signal bandwidth configuration information sent by a second communications device and flexibly configure the frequency domain bandwidth of the perception signal based on the perception signal bandwidth configuration information. In one embodiment, the perception signal is a DMRS for at least two terminals, thereby increasing the frequency domain bandwidth of the perception signal, thereby improving perception resolution. In one embodiment, if the frequency domain bandwidth of the perception signal is not configured through wireless signaling, the frequency domain bandwidth of the perception signal is equal to the DMRS frequency domain bandwidth of the current first communications device. In one example, the current first communications device refers to the communications device that transmits or receives the perception signal. In one example, when the existing DMRS is used as the perception signal and the frequency domain bandwidth of the perception signal is not configured through wireless signaling, if it is a downlink, the perception 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 can be used as the frequency domain bandwidth of the perception signal; if it is an uplink, the perception target can be measured based on the DMRS of the physical uplink shared signal (PUSCH) corresponding to the current first communication device, and the DMRS frequency domain bandwidth of the current first communication device can be used as the frequency domain bandwidth of the perception signal.

[0036] In one embodiment, when the frequency domain bandwidth of the perception signal is configured via wireless signaling, the frequency domain bandwidth of the perception signal is configured in units of the DMRS frequency domain bandwidth. In one example, when an existing DMRS is used as the perception signal and the frequency domain bandwidth of the perception signal is configured via wireless signaling, the frequency domain bandwidth of the perception signal can be configured in units of the DMRS frequency domain bandwidth, thereby resolving the issue of the perception signal bandwidth being limited by the DMRS bandwidth and improving perception resolution.

[0037] In one embodiment, configuring the frequency domain bandwidth of the perception signal in units of DMRS frequency domain bandwidth includes one of the following:

[0038] The frequency domain bandwidth of the perception signal is equal to the current bandwidth unit; wherein the current bandwidth unit is the DMRS frequency domain bandwidth of the current first communication device;

[0039] The frequency domain bandwidth of the perception signal is equal to the sum of a first preset number of bandwidth units before the current bandwidth unit and the current bandwidth unit;

[0040] The frequency domain bandwidth of the perception signal is equal to the sum of a first preset number of bandwidth units after the current bandwidth unit and the current bandwidth unit;

[0041] The frequency domain bandwidth of the perception signal is equal to the sum of a second preset number of bandwidth units before the current bandwidth unit, the current bandwidth unit, and a third preset number of bandwidth units after the current bandwidth unit;

[0042] The first preset number, the second preset number, and the third preset number are all integers greater than 0.

[0043] In one embodiment, configuring the frequency domain bandwidth of the perception signal in units of the DMRS frequency domain bandwidth includes: using a fourth preset number of bits of Radio Resource Control (RRC) signaling to indicate the frequency domain bandwidth of the perception signal. In one example, the fourth preset number is an integer greater than 0. For example, a fixed 1-bit RRC signaling may be used to indicate the frequency domain bandwidth of the perception signal, or a fixed 2-bit RRC signaling frequency domain bandwidth may be used. This is not limited to this.

[0044] In one embodiment, the frequency domain bandwidth of the perception signal includes at least one of the following: the current bandwidth unit; the current bandwidth unit and at least one bandwidth unit before the current bandwidth unit; the current bandwidth unit and at least one bandwidth unit after the current bandwidth unit. When an existing DMRS is used as the perception signal and at least one bit of RRC signaling is used to indicate the frequency domain bandwidth of the perception signal, the at least one bit of RRC signaling may be used to indicate that the current bandwidth unit is the frequency domain bandwidth of the perception signal, or the at least one bit of RRC signaling may be used to indicate that the total bandwidth of the current bandwidth unit and at least one bandwidth unit before the current bandwidth unit is used as the frequency domain bandwidth of the perception signal, or the at least one bit of RRC signaling may be used to indicate that the total bandwidth of the current bandwidth unit and at least one bandwidth unit after the current bandwidth unit is used as the frequency domain bandwidth of the perception signal, or the at least one bit of RRC signaling may be used to indicate that the total bandwidth of the current bandwidth unit, at least one bandwidth unit after the current bandwidth unit, and at least one bandwidth unit before the current bandwidth unit is used as the frequency domain bandwidth of the perception signal.

[0045] In one embodiment, the sensing signal is used as a reference signal for Quasi Co-Location (QCL) information in a Transmission Configuration Indicator (TCI) state.

[0046] In one embodiment, the reference signal types in the TCI state include at least a Sensing Target Reference Signal (STRS). In one example, the STRS can be added to the selection of reference signal types in the TCI state. This can also be understood as defining a new reference signal in the TCI state for target sensing, which can be called the STRS or the Sensing Function Reference Signal (SFRS).

[0047] In one embodiment, RRC signaling is used to indicate the starting resource block and total bandwidth length of the perception signal. In one example, the starting resource block is used to indicate the starting physical resource block (PRB) of the frequency domain resources corresponding to the newly defined perception signal relative to general resource block 0; the total bandwidth length is used to indicate the number of physical resource blocks occupied by the frequency domain resources corresponding to the newly defined perception signal.

[0048] In one embodiment, the QCL type between the STRS and another sensing target includes at least one of the following: Type E type;

[0049] The Type E type includes at least one of the following: Doppler shift, average delay, and average angle; Doppler shift, average delay, and average angle; average angle; and average radar cross section (RCS). In one example, a QCL relationship between a STRS and another sensing target signal can be newly defined. For example, the QCL type between the STRS and another sensing target includes at least one of the following: Type E type; the Type E type includes at least one of the following: Doppler shift, average delay, and average angle; Doppler shift, average delay, and average angle; average angle; and average RCS.

[0050] In one embodiment, FIG2 is a flowchart of another information configuration method provided by an embodiment of the present application. This embodiment is applied to the case of dynamically configuring the frequency domain bandwidth of the perception signal. This embodiment can be performed by a second communication device. As shown in FIG2, this embodiment includes: S210.

[0051] S210: Send perception signal bandwidth configuration information to the first communication device, so that the first communication device configures a frequency domain bandwidth corresponding to the perception signal based on the perception signal bandwidth configuration information.

[0052] In one embodiment, when the frequency domain bandwidth of the perception signal is not configured through wireless signaling, the frequency domain bandwidth of the perception signal is equal to the current DMRS frequency domain bandwidth of the first communication device.

[0053] In one embodiment, when the frequency domain bandwidth of the perception signal is configured through wireless signaling, the frequency domain bandwidth of the perception signal is configured in units of DMRS frequency domain bandwidth.

[0054] In one embodiment, configuring the frequency domain bandwidth of the perception signal in units of DMRS frequency domain bandwidth includes one of the following:

[0055] The frequency domain bandwidth of the perception signal is equal to the current bandwidth unit; wherein the current bandwidth unit is the DMRS frequency domain bandwidth of the current first communication device;

[0056] The frequency domain bandwidth of the perception signal is equal to the sum of a first preset number of bandwidth units before the current bandwidth unit and the current bandwidth unit;

[0057] The frequency domain bandwidth of the perception signal is equal to the sum of a first preset number of bandwidth units after the current bandwidth unit and the current bandwidth unit;

[0058] The frequency domain bandwidth of the perception signal is equal to the sum of a second preset number of bandwidth units before the current bandwidth unit, the current bandwidth unit, and a third preset number of bandwidth units after the current bandwidth unit;

[0059] The first preset number, the second preset number, and the third preset number are all integers greater than 0.

[0060] In one embodiment, configuring the frequency domain bandwidth of the perception signal in units of DMRS frequency domain bandwidth includes: using RRC signaling of a fourth preset number of bits to indicate the frequency domain bandwidth of the perception signal.

[0061] In one embodiment, the frequency domain bandwidth of the perception signal includes at least one of the following: the current bandwidth unit; the current bandwidth unit and at least one bandwidth unit before the current bandwidth unit; the current bandwidth unit and at least one bandwidth unit after the current bandwidth unit.

[0062] In one embodiment, the sensing signal is used as a reference signal for QCL information in the TCI state.

[0063] In one embodiment, the reference signal type in the TCI state includes at least: STRS.

[0064] In one embodiment, RRC signaling is used to indicate the starting resource block and the total bandwidth length of the perception signal.

[0065] In one embodiment, the QCL type between the STRS and another sensing target includes at least one of the following: Type E type;

[0066] 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.

[0067] It should be noted that for the explanation of parameters such as the perception signal, perception signal bandwidth configuration information, frequency domain bandwidth of the perception signal, STRS, etc. involved in the information configuration method applied to the second communication device, please refer to the description of the corresponding parameters in the above-mentioned information configuration method applied to the first communication device, and will not be repeated here.

[0068] In one embodiment, the configuration process of the frequency domain bandwidth of the perception signal is described using an existing reference signal as an example. The first communication device is denoted as the UE, and the second communication device is denoted as the base station. It is assumed that the first, second, and third preset numbers are all 1, and the fourth preset number K is 2.

[0069] Generally speaking, the synchronization signal and physical broadcast channel block (Synchronization Signal and PBCH block, SSB) only occupy a part of the frequency domain bandwidth. The Channel Status Information Reference Signal (CSI-RS) and Phase Tracing Reference Signal (PTRS) are usually much sparser than DMRS in the frequency domain (that is, the frequency domain density of DMRS is relatively higher), and the density of DMRS in the time domain is flexible and configurable. Therefore, DMRS is more suitable for sensing signals than CSI-RS and PTRS. However, the frequency domain bandwidth of DMRS is consistent with the scheduled PDSCH / PUSCH bandwidth. In the case of small bandwidth scheduling of PDSCH / PUSCH, the corresponding DMRS of the small bandwidth scheduled UE is not suitable for use as a sensing signal.

[0070] In view of this, the embodiment of the present application may adopt the DMRSs of at least two UEs as the perception signal, which may increase the frequency domain bandwidth of the perception signal.

[0071] Figure 3 is a schematic diagram of DMRS configurations for different UEs provided in an embodiment of the present application. As shown in (a) of Figure 3, if the PDSCHs of UE1 and UE2 are scheduled in a frequency division manner and the source reference signals of the QCL are the same (i.e., the base station uses the same transmit beam to target UE1 and UE2), the base station can use UE1DMRS and UE2DMRS as sensing signals, and instruct UE1 or UE2 through wireless signaling to sense the target based on UE1DMRS and UE2DMRS, and report the sensing measurement results.

[0072] The contents of wireless signaling instructions include:

[0073] First, if the frequency domain RB position of the perception signal is not configured through RRC signaling, the perception target can be measured based on the PDSCH DMRS of the current UE, and the frequency domain bandwidth of the perception signal is equal to the DMRS bandwidth of the current UE;

[0074] Secondly, if the frequency domain RB position of the perception signal is configured through RRC signaling, it can be configured in units of DMRS frequency domain bandwidth, for example,

[0075] If the bitmap signaling is 00100, it means that the frequency domain bandwidth of the perception signal is equal to the DMRS bandwidth of the current UE (recorded as the current bandwidth unit);

[0076] If the bitmap signaling is 01100, it means that the frequency domain bandwidth of the perception signal is equal to the previous bandwidth unit + the current bandwidth unit;

[0077] If the bitmap signaling is 01110, it means that the frequency domain bandwidth of the perception signal is equal to the previous bandwidth unit + the current bandwidth unit + the next bandwidth unit;

[0078] Alternatively, a fixed K-bit RRC signaling is used. For example, taking 2-bit signaling as an example:

[0079] As shown in (b) of FIG3 , if the DMRSs of UE1 and UE2 are not in the same time domain symbol, UE1 and UE2 sense the target separately and report the measurement results.

[0080] For uplink, SRS is flexible in both time and frequency domain configurations and can use a ZC sequence as a reference signal sequence. It has good autocorrelation characteristics and a low Peak to Average Power Ratio (PAPR), making it suitable for use as an uplink sensing signal.

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

[0082] Generally speaking, the existing QCL types for 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, all other large-scale parameters are the same, and the description of the target channel is more comprehensive. The UE can obtain a comprehensive description of the DM-RS characteristics, which is mostly used for channel demodulation.

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

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

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

[0087] In this embodiment, a new reference signal is defined for target perception, which can be called STRS or SFRS. Taking STRS as an example, STRS can be multiplexed with DMRS in a frequency division manner, or multiplexed with data in a time division manner, using a linear frequency modulated signal (LFM) sequence, a maximum-length sequence (m-sequence), a ZC (Zadoff–Chu) sequence, or a gold sequence.

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

[0089] The base station and UE can predefine that if the reference signal configured in QCL-Info is STRS and QCL-Type is typeA, STRS is used as DMRS; if QCL-Type is typeD, the STRS receive beam is used to receive PDSCH, or the transmit beam that is the same as or similar to the STRS receive beam is used to send PUSCH.

[0090] The starting resource block (RB) and total bandwidth length of the perception signal can be expressed using the following IE STRS - Frequency Occupation:

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

[0092] In addition, a new QCL relationship between a sensing target signal (i.e., STRS) and another sensing target signal (also referred to as sensing target) can be defined, for example, QCL type E:

[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] Among them, RCS is Radar Cross Section.
