Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication method and related apparatus. Background Technology

[0002] In recent years, wireless sensing technology has attracted widespread attention in academia. Wireless sensing technology analyzes changes in wireless signals during propagation to obtain the characteristics of the signal propagation space (channel), thereby achieving scene perception. The scene here includes both human factors (the presence, location, posture, and actions of people) and other external factors (such as buildings, moving vehicles, etc.). Radar is a classic wireless sensing method, widely used in transportation, agriculture, meteorology, and other fields. Its basic principle is that a transmitter emits a specific waveform signal, which travels through a wireless channel to be received by a receiver. By combining the transmitted and received signals, signal processing is performed to extract the target of interest within the wireless channel.

[0003] For wireless sensing applications, distance resolution is a key technical indicator, and it is related to signal bandwidth; the larger the bandwidth, the better the distance resolution performance. However, in existing wireless communication systems, a single frequency band often cannot meet the requirements for sensing ranging resolution. Therefore, multiple frequency bands can be aggregated to increase the effective sensing bandwidth, thereby improving resolution performance. Thus, how terminal devices should report sensing measurement results for multi-band sensing is a question worth considering. Summary of the Invention

[0004] This application provides a communication method and related apparatus for a first communication device to transmit first information. The first information indicates the sensing measurement results corresponding to each of multiple frequency bands. Alternatively, the first information indicates the sensing measurement results corresponding to at least one combination of frequency bands. This facilitates multi-band management or fusion sensing by network devices based on the first information, and helps improve the utilization rate of spectrum resources and / or enhance sensing performance.

[0006] In the above technical solution, for multi-band sensing, the first communication device can report the sensing measurement results of each frequency band, or it can report the sensing measurement results obtained by aggregating multiple frequency bands. This facilitates network devices to perform multi-band management or fusion sensing based on the first information. It is beneficial to improve the utilization rate of spectrum resources or enhance sensing performance.

[0007] A second aspect of this application provides a communication method applied to a second communication device. The method includes: the second communication device receiving first information, the first information indicating a sensing measurement result corresponding to each frequency band in a plurality of frequency bands; or, the first information indicating a sensing measurement result corresponding to at least one combination of frequency bands, each combination of frequency bands including at least one frequency band, and the at least one combination of frequency bands including a plurality of frequency bands; the second communication device managing the plurality of frequency bands according to the first information, or performing fusion sensing according to the first information.

[0010] This implementation provides two methods for reporting the sensing measurement results of a single frequency band as the first information. One method is to directly report the sensing measurement results of each frequency band, and the other is to report the sensing measurement results of each frequency band through differential reporting. This reduces the reporting overhead.

[0012] This implementation provides two methods for reporting the sensing measurement results of the first information reporting frequency band combination. One method is to directly report the sensing measurement results of each frequency band combination, and the other is to report the sensing measurement results of each frequency band combination through differential reporting.

[0081] This application provides a communication method and related apparatus for a first communication device to transmit first information. The first information indicates the sensing measurement results corresponding to each of multiple frequency bands. Alternatively, the first information indicates the sensing measurement results corresponding to at least one combination of frequency bands. This facilitates multi-band management or fusion sensing by network devices based on the first information, thereby improving the utilization rate of spectrum resources and / or enhancing sensing performance.

[0082] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0083] The term "and / or" appearing in this application can describe the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "or" relationship.

[0084] The following describes some of the technical terms used in this application.

[0085] Primary cell (PCell): This is the cell where the terminal device resides. The operations performed by the terminal device in this cell are no different from those performed in a single-carrier cell.

[0086] Secondary cell (SCell): A cell configured by the base station for the terminal device via radio resource control (RRC) signaling. A secondary cell can provide more radio resources to the terminal device. A secondary cell exists in the downlink direction, or simultaneously in both the uplink and downlink directions.

[0087] CC refers to the carriers corresponding to different cells participating in carrier aggregation.

[0088] Primary CC (PCC): refers to the CC corresponding to the primary cell.

[0089] Secondary CC (SCC): refers to the CC corresponding to the secondary cell.

[0090] The perceived target can also be called the target of interest. Furthermore, the perceived target can be replaced or equivalent to a path, meaning that measuring the perceived target can be replaced or equivalent to measuring a path. Each path can involve one or more perceived targets; the specific number is not limited here.

[0091] The measurement object can be equivalent to a cell, and the frequency domain resources used by the measurement object include one or more of the following: CC, frequency layer (FL), or bandwidth part (BWP). Alternatively, it can be understood that the frequency attributes of the measurement object include one or more of the following: CC, FL, or BWP, etc., without being limited here.

[0092] The primary function of a wireless communication system is to facilitate information exchange between transceivers. Its basic principle involves the transmitter sending a specific waveform signal, which is then received by the receiver via a wireless channel. After signal processing, the transmitted signal is demodulated. From the perspective of the entire physical process of transmission, reception, and communication, radar and wireless communication are remarkably similar. Therefore, how to integrate wireless communication with sensing technologies (represented by radar) to simultaneously achieve communication and environmental awareness has become a current research hotspot.

[0093] The integration of sensing and communication has been identified by the International Telecommunication Union (ITU) as one of the three new core capabilities of 6G, and at the 3GPP plenary meeting that concluded in September 2024, it was included as a representative capability in the first scenario requirement standard for 6G.

[0094] For wireless sensing applications, distance resolution is a key technical indicator, and distance resolution is related to signal bandwidth; the larger the bandwidth, the better the distance resolution performance. However, in existing wireless communication systems, each single frequency band often cannot meet the requirements of sensing ranging resolution. Therefore, how to aggregate multiple spectrums to increase the effective bandwidth of sensing and thus improve resolution performance is a problem worthy of research.

[0095] To provide higher communication speeds, the 3rd Generation Partner Project (3GPP) proposed a downlink speed requirement of 1 Gbit / s in the Long Term Evolution Advanced (LTE-Advanced) phase. However, due to factors such as the scarcity of radio spectrum resources, each single frequency band could not meet the bandwidth requirements of LTE-Advanced. For these reasons, 3GPP introduced carrier aggregation (CA) in Release 10. Figure 1 As shown, the access network device aggregates multiple CCs into a larger bandwidth and communicates with the terminal device.

[0096] The following is combined with Figures 2a to 2e This section introduces some communication carrier aggregation scenarios.

[0097] Figure 2a This is a schematic diagram of a communication carrier aggregation scenario. (Example) Figure 2a As shown, a base station operates simultaneously in frequency band F1 and frequency band F2, and the signal coverage of frequency band F1 is comparable to that of frequency band F2.

[0098] Figure 2b This is a schematic diagram of another scenario for communication carrier aggregation. (Example:) Figure 2b As shown, a base station operates simultaneously in frequency bands F1 and F2, and the signal coverage areas of frequency band F1 and F2 are different. However, the signal coverage areas of frequency band F1 and F2 overlap.

[0099] Figure 2c This is another schematic diagram illustrating a communication carrier aggregation scenario. (Example) Figure 2c and Figure 2b Similar, but different in that: Figure 2c In this context, the base station can cover corner areas by using the signal coverage ranges corresponding to frequency bands F1 and F2, respectively.

[0100] Figure 2d This is another schematic diagram illustrating a communication carrier aggregation scenario. (Example) Figure 2d As shown, macro base stations operate in frequency band F1, and small base stations operate in frequency band F2. The signal coverage area of ​​frequency band F1 includes the signal coverage area of ​​frequency band F2. Typically, frequency band F1 is used for communication, and frequency band F2 is used to enhance communication throughput in hotspot areas.

[0101] Figure 2e This is another schematic diagram illustrating a communication carrier aggregation scenario. (Example) Figure 2e and Figure 2b Similarly, but with a difference: additional small base stations are added, which provide signal coverage via the F2 frequency band. This enhances coverage.

[0102] Figure 3 This is a diagram illustrating the configuration, activation, and deactivation of a secondary cell. (Example) Figure 3 As shown, after carrier aggregation is enabled, the network device configures a secondary cell for the terminal device during initial access, handover, or reconstruction of the access cell. After the secondary cell configuration is complete, the network device can activate and deactivate the secondary cell. In this application, the network device can activate one or more secondary cells for the terminal device. The secondary frequency band corresponding to these one or more secondary cells can be used for communication, sensing, or both. The specific configuration can be determined by the network device.

[0103] Currently, communication carrier aggregation management only involves communication. However, if future communication systems introduce sensing multi-carrier functionality, available spectrum resources are always limited. How should conflicts arise when communication and sensing use different spectrum resources? Therefore, in multi-carrier communication and sensing scenarios, how to collaboratively manage multiple carriers to improve spectrum resource utilization is a problem worth considering.

[0104] In carrier aggregation, the relationship between communication resources and sensing resources can be varied. Some possible scenarios are illustrated below.

[0105] like Figure 4a As shown, the set of frequency resources used for communication and the set of frequency resources used for sensing are the same set, meaning that the frequency resources in this set can be used for both communication and sensing. Figure 4b As shown, there is no overlap between the set of frequency resources used for communication and the set of frequency resources used for sensing. Figure 4c As shown, the set of frequency resources used for communication and the set of frequency resources used for sensing overlap. For example... Figure 4d As shown, the set of frequency resources used for communication includes a subset of frequency resources used for both communication and sensing. For example... Figure 4e As shown, the set of frequency resources used for sensing includes a subset of frequency resources used for both communication and sensing.

[0106] The following section introduces some possible allocation methods for communication and sensing resources.

[0107] 1. Static allocation method.

[0108] During the communication system design phase, network management devices can statically allocate resources based on estimated communication and sensing requirements. This approach is suitable for scenarios with relatively stable resource demands.

[0109] 2. Dynamic allocation method.

[0110] In communication systems, network management devices can dynamically allocate resources based on real-time communication and sensing needs. This approach is suitable for scenarios with significant fluctuations in resource requirements.

[0111] 3. Adaptive allocation method.

[0112] In communication systems, network management devices dynamically adjust resource allocation strategies based on communication needs, sensing requirements, and the performance indicators of the communication system. This approach is suitable for scenarios where resource adjustments are made according to real-time conditions.

[0113] 4. Priority-based allocation method.

[0114] In communication systems, network management devices allocate communication and sensing resources based on task priority. This approach is suitable for scenarios where resource allocation is based on task urgency.

Examples include centralized units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), and radio units (RUs). CUs and DUs can be separate entities or included within the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs). Alternatively, network equipment can be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, network equipment can be roadside units (RSUs).

[0183] It should be noted that CU (or CU-CP and CU-UP), DU, or RU may have different names in different systems, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called an open centralized unit (O-CU) or an open CU, DU can also be called an open distributed unit (O-DU), centralized unit control plane (CU-CP) can also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, centralized unit user plane (CU-UP) can also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU can also be called an open radio unit (O-RU). This application does not impose any specific limitations. Any of the units CU, CU-CP, CU-UP, DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules.

[0184] Optionally, the access network equipment may also include a module for implementing sensing functions (i.e., a sensing module). This module can be a new module or an existing module with functional extensions (e.g., sensing functions). The sensing module supports and / or implements sensing functions. For example, it processes sensing signals and / or enables inter-site coordination under sensing functions.

[0185] The communication system provided in this application can incorporate a sensing module to implement some or all sensing-related operations. The sensing module can also be called a sensing unit, sensing processing unit, sensing function module, sensing processor, etc., and this application does not specifically limit its name. The sensing module can be built into a network element of the communication system. For example, the sensing module can be built into: access network equipment, core network equipment, cloud server, or network management (OAM) to implement sensing-related functions. The OAM can be the network management of the core network equipment and / or the network management of the access network equipment. Alternatively, the sensing module can also be an independently set network element in the communication system. Optionally, the terminal equipment or the chip built into the terminal equipment can also include a sensing module to implement sensing-related functions.

[0186] Figure 11 This is another schematic diagram of the communication system according to an embodiment of this application. For example... Figure 11 As shown, network elements in a communication system are connected via interfaces (e.g., NG interfaces or Xn interfaces) or air interfaces. These network element nodes, such as core network equipment, access network equipment, terminal equipment, or one or more devices in the OAM (Operational Information Management) system, are equipped with one or more sensing modules (for clarity, ...). Figure 11 (Only one is shown in the image). Access network devices can be standalone access network nodes or comprise multiple access network nodes. For example, an access network device may include a CU and a DU. One or more sensing modules may also be configured in each of the CU and the DU.

[0187] Optionally, the access network device can be a single access network node or can include multiple access network nodes. For example, it can include CU and DU. One or more sensing modules can be configured in each of the CU and / or DU. Optionally, the CU can also be divided into CU-CP and CU-UP. One or more sensing modules can be configured in each of the CU-CP and / or CU-UP. The sensing modules are used to implement corresponding sensing functions. The sensing modules deployed in different network elements can be the same or different.

[0188] Figure 12 This is a schematic diagram of an ORAN system according to an embodiment of this application. The ORAN system includes a core network, access network equipment, and UEs. Optionally, the ORAN system may further include... Figure 12 Other components besides those shown are not specifically limited in this application.

[0189] Access network devices can communicate with the core network (CN) via a backhaul link. Access network devices can also communicate with the UE via an air interface. Specifically, the BBU in the access network device communicates with the core network via a backhaul link. The RU in the access network device communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located.

[0190] A BBU consists of at least one CU and at least one DU, and the CU and DU can communicate with each other via at least one midhaul link.

[0191] One possible implementation is, such as Figure 12As shown, the CU is a logical node that carries the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. Optionally, the CU may have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0192] Optional, such as Figure 13As shown, the CU can be divided into CU-CP and CU-UP. CU-CP is a logical node carrying the RRC layer and the Packet Data Convergence Protocol layer (PDCP-C), responsible for implementing the CU's control plane functions. CU-CP can interact with network elements in the core network that implement control plane functions. These network elements can be access and mobility function (AMF) network elements, such as the AMF network element in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the SDAP layer and the Packet Data Convergence Protocol layer (PDCP-U), responsible for implementing the CU's user plane functions. CU-UP can interact with network elements in the core network that implement user plane functions. In the core network, network elements used to implement user plane functions, such as the user plane function (UPF) network element in a 5G system, are responsible for forwarding and receiving data in terminal devices. The above configuration of CU and DU is merely an example; in practical applications, the functions of CU and DU can be configured as needed. For example, CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For instance, some functions of the RLC layer and protocol layer functions above the RLC layer can be placed in the CU, while the remaining functions of the RLC layer and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of CU or DU can be divided according to service type or other system requirements, such as by latency, placing functions that need to meet low latency requirements in the DU and functions that do not need to meet such latency requirements in the CU.

[0193] One possible implementation is, such as Figure 13 As shown, a DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0194] One possible implementation is, such as Figure 13 As shown, the RU is a logical node that carries both lower physical layer (PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP Transmit Receive Point (TRP), a Remote Radio Header (RRH), or other similar entities. In some examples, the Low-PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link.

[0195] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through the Lower-Layer Split CUS-Plane (LLS-CUS) interface. LLS-CUS may include a Lower-Layer Split control (LLS-C) interface and a Lower-Layer Splituser (LLS-U) interface, providing the control plane (C-Plane) and user plane (U-Plane) respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and RU. The DU and RU exchange management information via a Lower-Layer Split management (LLS-M) interface on the fronthaul link; the management plane (M-Plane) refers to non-real-time management operations between the DU and RU.

[0196] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0197] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. For ease of description, this application uses CU, CU-CP, CU-UP, DU, and RU as examples.

[0198] Optionally, in the ORAN system, one or more sensing modules can be configured in the CU and / or DU respectively. Optionally, the CU can also be divided into CU-CP and CU-UP. One or more sensing modules can be configured in the CU-CP and / or CU-UP respectively. The sensing modules are used to implement corresponding sensing functions.

[0199] Optionally, in an ORAN system, the sensing module can be a CU, or a CU-CP, or a CU-UP, or a DU, or a new module set in a RU.

[0200] Alternatively, the sensing module can be integrated with existing modules in the CU, CU-CP, CU-UP, DU, or RU, that is, the existing functional modules can be extended to enable them to realize sensing functions.

[0201] It should be noted that the access network equipment can be a device or apparatus with a chip, or a device or apparatus with integrated circuitry, or a chip, chip system, module, control unit, or circuit in the device or apparatus shown above; this application does not impose any specific limitation. It should also be noted that in this application, the term "access network equipment" can refer to either the access network equipment itself or the chip, module, control unit, or circuit within the access network equipment that performs the method provided in this application; this application does not impose any specific limitation.

[0202] The communication system to which this application applies includes: a first communication device and a second communication device. The first communication device is a terminal device or a network device, or a device within a terminal device (e.g., a chip, chip system, control unit, or circuit); or a device within a network device (e.g., a chip, chip system, control unit, or circuit). The second communication device is a network device, or a device within a network device (e.g., a chip, chip system, control unit, or circuit).

[0203] The first communication device has a sensing function. For example, the first communication device can sense information through self-transmission and self-reception. Alternatively, the first communication device can sense information with other communication devices. Optionally, the first communication device has a communication function. For example, the first communication device can communicate with other communication devices.

[0204] Optionally, the second communication device may be able to manage frequency bands and / or perform sensing fusion.

[0205] The technical solution of this application is described below with reference to specific embodiments.

[0206] Figure 14 This is a schematic diagram of one embodiment of the communication method described in this application. Please refer to... Figure 14 The method includes the following steps.

[0207] 1401. The first communication device measures the sensed signal.

[0208] Among them, the sensing signal is the sensing signal received through multiple frequency bands.

[0209] In one possible implementation, the first communication device acts as a receiver of sensing signals, receiving sensing signals transmitted by other communication devices through the multiple frequency bands. The first communication device then measures these sensing signals.

[0210] In another possible implementation, the first communication device acts as both the transmitter and receiver of the sensing signal. The first communication device sends the sensing signal, which is then received by the first communication device after passing through the sensing target.

[0211] It should be noted that the first communication device can also measure sensing signals in more frequency bands. These multiple frequency bands are selected by the first communication device from the frequency bands it measures. These multiple frequency bands can be coherently combined, or in other words, the sensing signals from these multiple frequency bands can be coherently combined. This is beneficial for increasing the effective bandwidth and improving ranging resolution and accuracy. For specific details on how this is implemented, please refer to the relevant introduction in the following section on first information.

[0212] 1402. The first communication device sends first information to the second communication device. The first information is used to indicate the sensing measurement results of each of the multiple frequency bands; or, the first information is used to indicate the sensing measurement results corresponding to at least one combination of frequency bands. Accordingly, the second communication device receives the first information from the first communication device.

[0213] The at least one frequency band combination includes multiple frequency bands. Each frequency band combination includes at least one frequency band. For example, the multiple frequency bands include frequency band 1, frequency band 2, and frequency band 3. The at least one frequency band combination includes frequency band combination 1 and frequency band combination 2, where frequency band combination 1 includes frequency band 1 and frequency band 2, and frequency band combination 2 includes frequency band 2 and frequency band 3.

[0214] Optionally, in an integrated sensing system, multiple frequency bands include primary and secondary frequency bands. Each frequency band combination includes a primary frequency band and optionally includes secondary frequency bands. For example, the multiple frequency bands include PCC, SCC1, and SCC2. The at least one frequency band combination includes frequency band combination 1, frequency band combination 2, and frequency band combination 3. Frequency band combination 1 includes PCC, frequency band combination 2 includes PCC and SCC1, and frequency band combination 3 includes PCC and SCC2.

[0215] Regarding the case where the first information is used to indicate the sensing measurement results of each of the multiple frequency bands, the following describes two possible implementation methods for the content included in the first information.

[0216] Implementation Method 1: The first information includes: sensing measurement data corresponding to each frequency band in multiple frequency bands. In this implementation method, the first communication device directly reports the sensing measurement data for each frequency band.

[0217] Optionally, the first information also includes the identifier of the frequency band corresponding to the sensing measurement data for each of the multiple frequency bands. This facilitates the second communication device in determining the frequency band corresponding to each sensing measurement result. For example, the first information includes what is shown in Table 4:

[0218] Table 4

[0219] Frequency band identification Sensing measurement data 1 Sensing measurement data 1 2 Sensing measurement data 2 3 Sensing measurement data 3

[0220] Implementation Method 2: The first information includes at least one of the following: at least one first amplitude difference, at least one first phase difference, a first reference amplitude, or a first reference phase.

[0221] Wherein, at least one first amplitude difference includes the amplitude difference between the sensing measurement data corresponding to a frequency band other than the reference frequency band and the sensing measurement data corresponding to the reference frequency band. At least one first phase difference includes the phase difference between the sensing measurement data corresponding to a frequency band other than the reference frequency band and the sensing measurement data corresponding to the reference frequency band. The first reference amplitude is the amplitude corresponding to the sensing measurement data corresponding to the reference frequency band, and the first reference phase is the phase corresponding to the sensing measurement data corresponding to the reference frequency band. For example, the multiple frequency bands include frequency band 1, frequency band 2, and frequency band 3. Frequency band 1 is the reference frequency band. At least one first amplitude difference includes: the amplitude difference between the sensing measurement data corresponding to frequency band 2 and the sensing measurement data corresponding to frequency band 1, and the amplitude difference between the sensing measurement data corresponding to frequency band 3 and the sensing measurement data corresponding to frequency band 1. At least one first phase difference includes: the phase difference between the sensing measurement data corresponding to frequency band 2 and the sensing measurement data corresponding to frequency band 1, and the phase difference between the sensing measurement data corresponding to frequency band 3 and the sensing measurement data corresponding to frequency band 1.

[0222] Optionally, the first information may further include at least one of the following: an identifier of the frequency band corresponding to the at least one first amplitude difference, an identifier of the frequency band corresponding to the at least one phase difference, or an identifier of a reference frequency band. For example, the first information may include what is shown in Table 5:

[0223] Table 5

[0224] Frequency band identification Sensing measurement data 1 Amplitude, Phase 2 Amplitude difference 1, Phase difference 1 3 Amplitude difference 2, Phase difference 2

[0225] For example, as shown in Table 2, frequency band 1 is the reference frequency band. The first information includes the amplitude, phase, amplitude difference 1, phase difference 1, amplitude difference 2, and phase difference 2 of the sensing measurement data of frequency band 1. Amplitude difference 1 is the amplitude difference between the sensing measurement data of frequency band 2 and the sensing measurement data of frequency band 1. Phase difference 1 is the phase difference between the sensing measurement data of frequency band 2 and the sensing measurement data of frequency band 1. Amplitude difference 2 is the amplitude difference between the sensing measurement data of frequency band 3 and the sensing measurement data of frequency band 1. Phase difference 2 is the phase difference between the sensing measurement data of frequency band 3 and the sensing measurement data of frequency band 1.

[0226] Optionally, the reference frequency band can be a default frequency band, a frequency band configured by the network device, a frequency band specified by the communication protocol, a predefined frequency band, or a frequency band selected based on preset principles. For example, the reference frequency band is the frequency band with the largest amplitude or the largest phase among the sensing measurement data corresponding to multiple frequency bands.

[0227] In this implementation, the first communication device reports the differential amplitude and / or differential phase between frequency bands, thereby reducing reporting overhead. The differential reporting method shown above is only one method of compressed reporting; other compressed reporting methods can also be used to report sensing measurement results, and this application does not limit the specific methods. This reduces reporting overhead.

[0228] Optionally, the content included in the first information above is merely an example. In practical applications, the first information may also include multipath identifiers, multipath timestamps, etc.

[0229] The following describes some possible methods for determining whether multiple frequency bands can be correlated and synthesized.

[0230] Implementation Method 1: Multiple frequency bands, including a first frequency band and a second frequency band. The bandwidth of the first frequency band is B1, the bandwidth of the second frequency band is B2, and a reference path is used. This reference path is a reference path with known distance, such as a line-of-sight (LOS) path, a reflection path formed by a target with known spatial location, or a reflection path formed by a reconfigurable intelligence surface (RIS). The ranging resolution obtained by sensing target 1 using the first frequency band is Δr1, and the ranging resolution obtained by sensing target 1 using the second frequency band is Δr2. The first information includes the sensing measurement data of frequency band 1 and the sensing measurement data of frequency band 2. The ranging resolution obtained by the network device based on the sensing measurement data of frequency band 1 and the sensing measurement data of frequency band 2 is Δr. If the first frequency band 1 and the second frequency band can be coherently combined, then the obtained ranging resolution satisfies the following conditions:

[0231]

[0232] in, c is the speed of light. Therefore,

[0233] The above describes the technical solution of this application by taking the coherent synthesis of the first and second frequency bands as an example. If there are more frequency bands, the method for judging whether each frequency band can be coherently synthesized with other frequency bands is similar, and will not be repeated here.

[0234] Implementation Method 2: Multiple frequency bands, including a first frequency band and a second frequency band, and the first information includes multiple first measurement values. These multiple first measurement values ​​are multiple phases obtained by measuring multipath signals using the first and second frequency bands. Alternatively, the multiple first measurement values ​​are multiple phase differences obtained by measuring multipath signals using the first and second frequency bands.

[0235] Among them, the plurality of first measured values ​​satisfy any of the following conditions:

[0236] The first difference is less than or equal to a first fitted straight line. The first difference is one or more distances from the plurality of first measurements to the first fitted straight line. Alternatively, the difference between the plurality of phase differences obtained by multipath measurements in the first and second frequency bands and the theoretical phase difference is less than or equal to the first threshold. Alternatively, the plurality of phase differences obtained by multipath measurements in the first and second frequency bands lie on a straight line or the line connecting the phase differences approximates a straight line.

[0237] The difference between the first difference and the first fitted line can be understood as the computational amount between the phase difference obtained from measuring the same sensing target in different frequency bands and the first fitted line. This computational amount can be understood as one or more phase differences from the measured value to the fitted line (e.g., subsequent...). Figure 15 The phase difference in the figure can also be understood as one or more perpendicular distances from the measured value to the fitted line (e.g., subsequent...). Figure 16 (d)

[0238] It should be noted that the first fitted straight line can be a straight line fitted by measuring the phase difference of the first path in the multipath using the first and second frequency bands. Alternatively, the first fitted straight line can be a straight line fitted by measuring the phase difference of the first path in the multipath using the first and second frequency bands as a function of distance or time delay. Here, each path is associated with a distance or time delay. Or, each path is associated with a time delay or the corresponding phase difference. Optionally, the first path can be one or more paths or all paths in the multipath. For example, the first path can be the top N paths after sorting the multipaths by measurement intensity from high to low, where N is an integer greater than or equal to 1. Another example is that the first path can also be the top N paths after sorting the multipaths by intensity from low to high. Yet another example is that the first path can also be N random paths, where N is an integer greater than or equal to 1; the specific choice is not limited here. Alternatively, the paths used for the first fitted straight line can be all the measured paths, or a portion of the measured multipaths, etc.

[0239] To facilitate understanding of the relationship between the fitted phase difference and the aforementioned first fitted line, the following description will use the CC frequency band as an example. The first frequency band is CC1, and the second frequency band is CC2.

[0240] For example, taking CC1 and CC2 as examples, assume the center frequency of CC1 is f1 and the center frequency of CC2 is f2. For the same sensing target (or the same path), the propagation delay of the signal transmitted by the transmitter (TX) to the receiver (RX) after passing through the sensing target is τ. In addition to the phase introduced by the propagation delay, the transceiver system introduces phases ψ1 and ψ2 on CC1 and CC2, respectively. Then, at the receiver, for a sensing target with a time delay of τ, the corresponding phases φ1(τ) on CC1 and φ2(τ) on CC2 can be expressed as follows:

[0241] φ1(τ)=2πf1τ+ψ1;

[0242] φ2(τ)=2πf2τ+ψ2;

[0243] Furthermore, the phase difference between the signals received by the two CCs on the same sensing target can be expressed as:

[0244] Δφ 12 (τ)=2πΔf 12 τ+Δψ 12 ;

[0245] The above equation is a linear equation, where Δf 12 and Δψ12 To determine the value, Δφ 12 (τ) changes with τ. That is, when two CCs are coherent, the phase difference between the two CCs changes linearly with distance.

[0246] For example, taking phase difference and five sensing targets or paths as an example, based on the measured values ​​obtained from CC1 and CC2 and the straight line (i.e., the fitted straight line or theoretical phase) obtained by fitting the measured values, it can be as follows: Figure 15 As shown, for a single sensing target, the horizontal axis represents the distance to that target, and the vertical axis represents the phase measured on CC1 and CC2. Now, for five sensing targets, assuming each target corresponds to a different distance (i.e., each target corresponds to a point on a two-dimensional plane with two values: distance or time delay, and phase difference), theoretically, if CC1 and CC2 can be coherently combined, the phase differences of these five targets should lie on a straight line (i.e., the straight line represented by the linear equation above).

[0247] For example, if a phase difference is obtained by measuring a single sensing target using multiple frequency bands, then multiple phase differences can be obtained by measuring multiple sensing targets using multiple frequency bands. If the multiple frequency bands can be coherently combined, or if the ranging resolution after combining multiple frequency bands can be improved, then the multiple phase differences should be on a straight line. If the multiple frequency bands cannot be coherently combined, or if the ranging resolution after combining multiple frequency bands cannot be improved, then the multiple phase differences will not be on a straight line.

[0248] For example, taking the vertical distance (d) and five sensing targets or paths as an example, the measured values ​​obtained from CC1 and CC2, and the straight line (i.e., the fitted line or theoretical phase) fitted from the measured values, can be as follows: Figure 12 As shown, for a single sensing target, the horizontal axis represents the distance to that target, and the vertical axis represents the phase measured on CC1 and CC2. Theoretically, if CC1 and CC2 can be coherently combined, the phase differences of multiple sensing targets should lie on a straight line (i.e., the straight line represented by the linear equation above). Therefore, the fitted line obtained by fitting the measured values ​​should theoretically be a line that can be coherently combined. The difference from coherent combination can be reflected by the vertical distance *d* from the measured values ​​to the fitted line. For example, in this example, the difference can be measured by the computational cost of five *d* values ​​corresponding to five sensing targets. This computational cost can include one or more of the following: maximum value, average value, square root of square, or multiplication, etc.

[0249] Accordingly, the phase difference is one or more distances from multiple first measurements to the fitted straight line, where the multiple first measurements are multiple phase differences obtained by measuring multipath based on a first frequency band and a second frequency band. The calculated value among these multiple distances is less than or equal to a first threshold. These multiple distances are the distances between the measured multiple phase differences and the first fitted straight line obtained by fitting the multiple phase differences. The calculated values ​​may include one or more of the following: maximum value, minimum value, average value, variance, standard deviation, square root of square, or multiplicative value, etc.

[0250] Therefore, these multiple first measurements can be used by the second communication device to perform coherent synthesis in order to achieve multi-band sensing, which is beneficial to improving sensing resolution.

[0251] Implementation Method 3: Assume a reference path is given, which is either a reference path with a known distance, a LOS path, a reflection path formed by a target with a known spatial location, or a reflection path formed through a RIS. The time delay of the reference path is τ. For example, the first frequency band and the second frequency band are used as examples, and the following description will use CC1 for the first frequency band and CC2 for the second frequency band.

[0252] Assume the center frequency of CC1 is f1 and the center frequency of CC2 is f2. For the same sensing target or the same multipath, the propagation delay of the signal transmitted by the transmitter to the receiver after passing through the sensing target is τ. In addition to the phase introduced by the propagation delay, the transceiver system introduces phases ψ1 and ψ2 on CC1 and CC2, respectively (assuming that these two phases are known).

[0253] At the receiving end, for a reference path with a time delay of τ, the phase φ1(τ) on CC1 and the phase φ2(τ) on CC2 can be expressed as follows:

[0254] φ1(τ)=2πf1τ+ψ1;

[0255] φ2(τ)=2πf2τ+ψ2;

[0256] Furthermore, on the same reference path, the phase difference between the received signals on the two CCs can be expressed as:

[0257] Δφ 12 (τ)=2πΔf 12 τ+Δψ 12 ;

[0258] Since we assume that ψ1 and ψ2 are both known, the above equation can be further written as:

[0259] Δφ 12 (τ)-Δψ 12 =2πΔf 12 τ

[0260] Where Δf and τ are both known, if the two CCs can be coherently synthesized, then the above equation holds. However, considering the influence of error, we require:

[0261] |Δφ 12 (τ)-Δψ 12 -2πΔf 12 τ|≤ phase threshold

[0262] In other words, the first information can include the phase obtained by the terminal device by measuring the sensing signals corresponding to frequency band 1 and frequency band 2 for a reference path with a time delay of τ. The network device can determine whether frequency band 1 and frequency band 2 can be coherently synthesized based on the phase included in the first information.

[0263] Regarding the case where the first information is used to indicate the sensing measurement results corresponding to at least one frequency band combination, two possible implementation methods for the content of the first information are described below.

[0264] Implementation Method 1: The first information includes: sensing measurement data corresponding to each frequency band combination in at least one frequency band combination.

[0265] In this implementation, the first communication device directly reports the sensing measurement data for each frequency band combination. It should be noted that for a frequency band combination, which includes multiple frequency bands, the sensing measurement data is obtained by the first communication device coherently combining the sensing signals received from the multiple frequency bands, and then determining the data based on the coherently combined signal.

[0266] Optionally, the first information may also include an identifier or index of the frequency band combination corresponding to the sensing measurement data for each frequency band combination in at least one frequency band combination. For example, the first information may include what is shown in Table 6:

[0267] Table 6

[0268] Frequency band combination identifier Sensing measurement data 1 Sensing measurement data 1 2 Sensing measurement data 2 3 Sensing measurement data 3

[0269] Implementation Method 2: At least one frequency band combination includes multiple frequency band combinations. The first information includes: at least one second amplitude difference, at least one second phase difference, a second reference amplitude, or a second reference phase.

[0270] Wherein, at least one second amplitude difference includes the amplitude difference between the sensed measurement data corresponding to a frequency band combination other than the reference frequency band combination and the sensed measurement data corresponding to the reference frequency band combination. At least one second phase difference includes the phase difference between the sensed measurement data corresponding to a frequency band combination other than the reference frequency band combination and the sensed measurement data corresponding to the reference frequency band combination. The second reference amplitude is the amplitude corresponding to the sensed measurement data corresponding to the reference frequency band combination, and the second reference phase is the phase corresponding to the sensed measurement data corresponding to the reference frequency band combination. For example, at least one frequency band combination includes frequency band combination 1, frequency band combination 2, and frequency band combination 3. Frequency band combination 1 is the reference frequency band combination. At least one second amplitude difference includes the amplitude difference between the sensed measurement data corresponding to frequency band combination 2 and the sensed measurement data corresponding to frequency band combination 1, and the amplitude difference between the sensed measurement data corresponding to frequency band combination 3 and the sensed measurement data corresponding to frequency band combination 1. At least one second phase difference includes the phase difference between the sensed measurement data corresponding to frequency band combination 2 and the sensed measurement data corresponding to frequency band combination 1, and the phase difference between the sensed measurement data corresponding to frequency band combination 3 and the sensed measurement data corresponding to frequency band combination 1.

[0271] Optionally, the first information may further include at least one of the following: an identifier of at least one frequency band combination corresponding to the at least one second amplitude difference, an identifier of the frequency band combination corresponding to the at least one second phase difference, or an identifier of a reference frequency band combination. For example, the first information may include what is shown in Table 7:

[0272] Table 7

[0273] Frequency band combination identifier Sensing measurement data 1 Amplitude, Phase 2 Amplitude difference 1, Phase difference 1 3 Amplitude difference 2, Phase difference 2

[0274] For example, as shown in Table 7, frequency band combination 1 is a reference frequency band combination. The first information includes the amplitude and phase of the sensing measurement data of frequency band combination 1, the amplitude difference 1 and phase difference 1 between the sensing measurement data corresponding to frequency band combination 1 and frequency band combination 2, and the amplitude difference 2 and phase difference 2 between the sensing measurement data corresponding to frequency band combination 1 and frequency band combination 3, respectively.

[0275] Optionally, the reference frequency band combination can be a default frequency band combination, a frequency band combination configured by the network device, a frequency band combination specified by the communication protocol, a predefined frequency band combination, or a frequency band combination selected based on preset principles. For example, the reference frequency band combination is the frequency band with the largest amplitude among the sensing measurement data corresponding to multiple frequency band combinations. Another example is a frequency band combination that only contains the primary frequency band.

[0276] In this implementation, the first communication device reports sensing measurement results at the granularity of frequency band combinations, which helps reduce reporting overhead. Furthermore, the first communication device reports the differential amplitude and / or differential phase between frequency band combinations, further reducing reporting overhead.

[0277] Optionally, at least one frequency band combination includes multiple frequency band combinations, including a first frequency band combination and a second frequency band combination. The first information includes multiple second measurements, which are multiple phase differences obtained by measuring multipath through the first and second frequency band combinations. The difference between the second difference and a second fitted straight line is less than or equal to a second threshold, where the second difference is one or more distances between the multiple second measurements and the second fitted straight line. Alternatively, the difference between the multiple phase differences obtained by measuring multipath through the first and second frequency band combinations and the theoretical phase difference is less than or equal to the second threshold. Alternatively, the multiple phase differences obtained by measuring multipath through the first and second frequency band combinations are on a straight line or the line connecting the phase differences approximates a straight line.

[0278] It should be noted that the second fitted line can be a straight line obtained by fitting the phase difference of the first path in the multipath using the combination of the first and second frequency bands. Alternatively, the second fitted line can be a straight line obtained by fitting the phase difference of the second path in the multipath using the combination of the first and second frequency bands as a function of distance or time delay. Here, each path is associated with a distance or time delay. Or, each path is associated with a time delay or the corresponding phase difference. Optionally, the second path can be one or more paths or all paths in the multipath. For example, the second path can be the top M paths after sorting the multipaths by measurement intensity from high to low. Here, M is an integer greater than or equal to 1. Another example is that the second path can also be the top M paths after sorting the multipaths by intensity from low to high. Yet another example is that the first path can also be M random paths, etc., without specific limitations here. Alternatively, it can be understood that the paths used to fit the straight line can be all the measured paths, or a portion of the measured multipaths, etc.

[0279] For relevant examples of this implementation, please refer to the preceding text. Figure 15 and Figure 16 The relevant information will not be repeated here.

The quality configuration includes a communication quality configuration, and the measurement interval includes a communication measurement interval.

[0294] Optional, Figure 14 The illustrated embodiment also includes step 1400. Step 1400 may be performed prior to step 1401a.

[0298] The information supported by the first communication device for simultaneous measurement of multiple frequency bands includes at least one of the following: the maximum number of frequency bands that the first communication device supports for simultaneous measurement of multiple frequency bands, or the maximum bandwidth that the first communication device supports for simultaneous measurement of multiple frequency bands.

[0299] The information supported by the first communication device for multi-band time-division frequency hopping measurement includes at least one of the following: the maximum number of frequency bands supported by the first communication device for multi-band time-division frequency hopping measurement, the maximum bandwidth supported by the first communication device for multi-band time-division frequency hopping measurement, or the minimum time interval supported by the first communication device for multi-band time-division frequency hopping measurement.

[0300] The aforementioned measurement capability information can characterize the uplink measurement capability, downlink measurement capability, and / or sidelink measurement capability of the first communication device. For most terminal devices, uplink measurement capability and downlink measurement capability are generally not equivalent.

[0301] Optionally, the processing capability information includes at least one of the following: whether the first communication device has the ability to process sensing measurement data to obtain distance information, angle information, and / or speed information; whether the first communication device has the ability to process sensing measurement data corresponding to different frequency bands to obtain amplitude difference and / or phase difference of sensing measurement data corresponding to different frequency bands; or whether the first communication device supports the ability to aggregate sensing measurement results corresponding to multiple frequency bands.

[0304] The ability to process sensing measurement results obtained from multi-band time-division frequency hopping measurements includes at least one of the following: the maximum number of frequency bands that the first communication device can process, or the maximum bandwidth that the first communication device can process for multiple frequency bands.

[0305] It should be noted that if the first communication device does not support the ability to process sensing measurement results obtained from simultaneous measurements of multiple frequency bands, the processing capability information can support the maximum bandwidth of a single frequency band that the first communication device can process.

[0306] Optionally, the sensing measurement result reporting capability information includes at least one of the following: the first communication device supports reporting raw sensing measurement data, CIR data, RV data, RAV data, amplitude difference between sensing measurement data corresponding to different frequency bands, phase difference between sensing measurement data corresponding to different frequency bands, sensing measurement results obtained by multi-frequency band aggregation, or sensing measurement results of a single frequency band.

[0307] Optionally, the second communication device determines the reporting format based on the capability information. That is, the reporting format is related to the measurement capability information, processing capability information, and sensing measurement result reporting capability information. For example, if the first communication device's measurement capability supports simultaneous multi-band measurement, its processing capability supports simultaneous multi-band measurement, and its sensing measurement result reporting capability supports reporting sensing measurement results obtained from multi-band aggregation, then the reporting format can be the sensing measurement results obtained from multi-band aggregation. As another example, if the first communication device's measurement capability supports multi-band time-division frequency hopping measurement, its processing capability supports processing sensing measurement results obtained from multi-band time-division frequency hopping measurement, and its sensing measurement result reporting capability supports reporting sensing measurement results obtained from multi-band aggregation, then the reporting format can be the sensing measurement results obtained from multi-band aggregation. Yet another example: if the first communication device's measurement capability supports multi-band time-division frequency hopping measurement, its processing capability does not support processing sensing measurement results obtained from multi-band time-division frequency hopping measurement, but its sensing measurement result reporting capability supports reporting sensing measurement results obtained from multi-band aggregation, then the reporting format can be the sensing measurement results of a single frequency band.

[0309] 1401b. The second communication device sends second configuration information to the first communication device, the second configuration information being used to configure the mode used for communication and sensing. Correspondingly, the first communication device receives the second configuration information from the second communication device.

[0310] The mode used for communication and sensing can be any of the modes 1-1 to 6-4 shown above.

[0311] Optionally, the second configuration information is carried in RRC signaling.

[0312] Optionally, there is no fixed execution order between steps 1401a and 1401b. For example, step 1401a can be executed first, followed by step 1401b; or step 1401b can be executed first, followed by step 1401a; or, depending on the circumstances, steps 1401a and 1401b can be executed simultaneously. This application does not impose any specific restrictions on this.

[0313] Optionally, the second configuration information and the first configuration information are the same configuration information. For example, as can be seen from the first configuration information above, the mode indication information (communication-sensing mode type) is used to indicate the mode.

[0314] Optionally, step 1402 specifically includes: the first communication device sending first information through a reporting method corresponding to the mode. For details on the reporting method corresponding to the mode, please refer to the reporting methods shown in Table 3 above. For example, in mode 2-2, the first communication device sends the first information through an uplink channel (e.g., PUCCH or PUSCH).

[0315] Optional, Figure 14 The illustrated embodiment also includes step 1403, which can be performed after step 1402.

[0316] 1403. The second communication device manages multiple frequency bands based on the first information, or performs fusion sensing based on the first information.

[0317] For example, the second communication device can determine the sensing measurement results of multiple frequency bands through the content of the first information, thereby understanding the joint sensing performance of multiple frequency bands, which is conducive to improving the effectiveness of frequency band management.

[0318] For example, the second communication device performs fusion sensing based on the content of the first information to achieve multi-band sensing, which helps to improve sensing resolution and sensing performance.

[0319] In this embodiment, the first communication device measures sensing signals, which are sensing signals received through multiple frequency bands. The first communication device sends first information, which indicates the sensing measurement result corresponding to each frequency band in the multiple frequency bands; or, the first information indicates the sensing measurement result corresponding to at least one combination of frequency bands, where each combination includes at least one frequency band, and the at least one combination includes multiple frequency bands. Therefore, for multi-band sensing, the first communication device can report the sensing measurement result of each frequency band, or it can report the sensing measurement result obtained by aggregating multiple frequency bands. This facilitates network devices in performing multi-band management or fusion sensing based on the first information, which is beneficial for improving the utilization rate of spectrum resources or enhancing sensing performance.

[0355] Input / output devices can include touchscreens, displays, or keyboards. They are primarily used to receive user input and output data to the user. It should be noted that some types of terminal devices may not have input / output devices.

[0356] When data needs to be transmitted, the processor performs baseband processing on the data to be transmitted and outputs a baseband signal to the radio frequency (RF) circuit. The RF circuit then processes the baseband signal and transmits it outwards as electromagnetic waves via an antenna. When data is sent to the terminal device, the RF circuit receives the RF signal through the antenna. The RF circuit converts the RF signal back into a baseband signal and outputs it to the processor. The processor converts the baseband signal back into data and processes that data. For ease of explanation, Figure 19 Only one memory, processor, and transceiver are shown in the illustration. In actual terminal devices, there may be one or more processors and one or more memories.

[0362] When the communication device 1900 is a chip, the chip includes a processor and a transceiver. The processor can be a processing module integrated on the chip, a microprocessor, or an integrated circuit. The transceiver can be an input / output circuit or a communication interface. In the above method embodiments, the transmitting operation of the first or second communication device can be understood as the output of the chip, and the receiving operation of the first or second communication device in the above method embodiments can be understood as the input of the chip.

[0365] When the communication device 2000 is a network device, such as a base station. Figure 20 A simplified schematic diagram of a base station structure is shown. The base station includes parts 2010, 2020, and 2030.

[0366] The 2010 section is mainly used for baseband processing and controlling the base station; the 2010 section is usually the control center of the base station, which can usually be called a processor, and is used to control the base station to perform the processing operations on the first communication device or the second communication device side in the above method embodiments.

[0367] The 2020 section is primarily used to store computer program code and data.

[0368] Section 2030 is primarily used for transmitting and receiving radio frequency (RF) signals, as well as converting RF signals to baseband signals. Section 2030 is commonly referred to as a transceiver module, transceiver, transceiver circuit, or transceiver unit. The transceiver module of section 2030, also known as a transceiver or transceiver unit, includes antenna 2033 and RF circuitry (not shown in the figure), where the RF circuitry is mainly used for RF processing. Optionally, the device in section 2030 that implements the receiving function can be considered a receiver, and the device that implements the transmitting function can be considered a transmitter; that is, section 2030 includes receiver 2032 and transmitter 2031. The receiver can also be called a receiving module, receiver circuit, or receiving circuit, and the transmitter can be called a transmitting module, transmitter, or transmitting circuit.

[0369] The 2010 and 2020 sections may include one or more single boards, each of which may include one or more processors and one or more memories. The processors are used to read and execute programs in the memories to implement baseband processing functions and control the base station.
