Description

An information measurement method and communication device

[0001] This application claims priority to Chinese Patent Application No. 202411918204.3, filed on December 23, 2024, with the China National Intellectual Property Administration, entitled "An Information Measurement Method and Communication Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to an information measurement method and communication device. Background Technology

[0003] Deterministic transmission refers to ensuring predictable latency and jitter in network communication to meet the needs of time-sensitive applications. This transmission method is crucial for scenarios such as remote surgery, industrial automation, and autonomous driving, because these applications require data transmission latency and jitter to be kept within acceptable ranges to ensure operational safety and accuracy.

[0004] Multiple-input multiple-output (MIMO) and downlink precoding (also known as beamforming) are key technologies for ensuring deterministic transmission. Downlink precoding not only affects the deterministic transmission of user equipment (UE) within the same cell but also affects UEs in neighboring cells, causing interference with them, and this interference exhibits strong random fluctuation characteristics. Taking cell 1 as an example, assuming cell 2 is a neighboring cell of cell 1, scheduling UE2 in cell 2 will interfere with UE1 in cell 1. If cell 2 does not serve UE2 as a single user but rather multiple users simultaneously serve UE2 and UE3, then when scheduling UE2, cell 2 will adjust UE2's precoding to avoid intra-cell multi-user interference with UE3. This changes the interference to UE1 when scheduling UE2, making it impossible for UE1 to accurately measure this interference information, causing fluctuations in UE1's channel quality indicator (CQI), and thus affecting the deterministic transmission of deterministic services.

[0005] Therefore, how to accurately measure the interference of neighboring cells on the current cell in order to ensure the deterministic transmission of deterministic services is an urgent problem to be solved. Summary of the Invention

[0006] This application provides an information measurement method and a communication device. Based on the method described in this application, the interference of neighboring cells to the current cell can be accurately measured, thereby ensuring the deterministic transmission of deterministic services.

[0007] Firstly, embodiments of this application provide an information measurement method, which can be applied to the terminal side, such as a terminal or a communication module / processing module in the terminal, or a circuit or chip in the terminal responsible for communication functions (such as a modem chip, also known as a baseband chip, or a system-on-chip (SoC) chip containing a modem core or a system-in-package (SIP) chip), or a circuit or chip in the terminal responsible for processing functions (such as a graphics processing unit (GPU), an artificial intelligence (AI) processor, or an application-specific integrated circuit (ASIC)). Taking the application of this method to a first terminal device as an example, in this method:

[0008] The first terminal device receives first configuration information from the first network device, which is used to configure a first sequence to be measured. The first terminal device accesses a first cell, and the first sequence is a sequence of first reference signals used by at least one second terminal device in a second cell. Then, the first reference signal is measured according to the first sequence.

[0009] Using the above method, taking a first terminal device and a second terminal device as examples, the first terminal device accesses a first cell, and the first network device manages the first cell; the second terminal device accesses a second cell, and the second network device manages the second cell. The second cell can be a neighboring cell of the first cell. The first reference signal used by the second network device when scheduling the second terminal device may interfere with the first terminal device in the first cell. Therefore, the second terminal device can be considered an interfering device targeting the first terminal device, and the first reference signal can be considered an interference signal targeting the first terminal device. The first network device can configure the sequence of the first reference signal (i.e., the first sequence) used by the second network device when scheduling the second terminal device to the first terminal device. Since the first reference signal is generated based on the first sequence, the first terminal device can separate the first reference signal from several signals based on the first sequence for measurement. This allows the first terminal device to more accurately measure the interference from neighboring cells to its own cell. Subsequently, the first network device can configure transmission resources that guarantee delay constraints for the first terminal device based on the interference distribution (i.e., the interference fluctuation range), such as a more robust modulation and coding scheme (MCS), thereby ensuring deterministic transmission of deterministic services.

[0010] In one possible implementation, the method further includes: a first terminal device sending interference statistics to a first network device, the interference statistics being determined based on the energy of the first reference signal.

[0011] Using the above method, after the first terminal device measures the first reference signal, it can further feed back the monitored interference statistics (i.e. interference fluctuation range) to the first network device, so that the first network device can combine the interference statistics to configure more reliable transmission resources (such as more robust MCS) for the first terminal device, and ensure the deterministic transmission of deterministic services.

[0012] In one possible implementation, the interference statistics include at least one of the following: the average energy of the first reference signal, the variance of the energy of the first reference signal, or the energy value corresponding to a first probability on a first probability distribution function; the first probability distribution function is the probability distribution function corresponding to the energy of the first reference signal.

[0013] In one possible implementation, the first configuration information also includes a first probability. This approach helps the base station select a more robust MCS, thereby improving transmission reliability.

[0014] In one possible implementation, the method further includes: a first terminal device receiving second configuration information from a first network device, the second configuration information including a first probability. This approach helps the base station select a more robust MCS, thereby improving transmission reliability.

[0015] In one possible implementation, the first configuration information includes the random seed used to generate the first sequence.

[0016] Using the above method, taking the first reference signal as a demodulation reference signal (DMRS) as an example, the first network device uses the first configuration information to generate the random seed (i.e., C) used to generate the first sequence. init The first terminal device can then use its own DMRS sequence generation formula and the random seed (i.e., C) indicated by the first configuration information to generate the sequence. init The first sequence is generated. This first sequence is the DMRS sequence used by the second network device when scheduling the second terminal device in the second cell. This method indirectly configures the first sequence to the first terminal device, saving signaling overhead.

[0017] In one possible implementation, the first configuration information includes a first transmission resource or a first set of transmission resources; the specific implementation of the first terminal device measuring the first reference signal according to the first sequence may be: measuring the first reference signal according to the first sequence on the first transmission resource or the first set of transmission resources.

[0018] Using the above method helps the first terminal device to measure the first reference signal more accurately on the corresponding transmission resources or set of transmission resources.

[0019] In one possible implementation, the first transmission resource includes at least one of the following: the bandwidth occupied by the first reference signal, the location of the resource block occupied by the first reference signal, the location and number of time-domain symbols occupied by the first reference signal, the configuration type of the first reference signal, the identifier of the antenna port used by the first reference signal, or the orthogonal code used by the first reference signal.

[0020] In one possible implementation, the method further includes: a first terminal device measuring a second synchronization signal block of the second cell, the energy of which is greater than or equal to a first threshold value; and then sending an identifier of the first beam corresponding to the second synchronization signal block to a first network device.

[0021] Using the above method helps to identify the beam that has strong interference to the first terminal device (i.e., the first beam), which facilitates the subsequent information exchange between the first network device and the second network device on the strong interference beam. The second network device can determine which terminal devices used these beams when scheduling them, and feed back the sequence of the first reference signal used when scheduling the second terminal device (i.e., the first sequence) to the first network device, thereby enabling the first network device to obtain the first sequence and improve the accuracy of interference measurement.

[0022] In one possible implementation, the first threshold value is associated with the energy of the first synchronization signal block of the first cell. This approach improves the flexibility of setting the first threshold value.

[0023] In one possible implementation, the method further includes: a first terminal device measuring a first channel status information reference signal (CSI-RS) whose energy is greater than or equal to a second threshold value; and then sending the identifier of the second beam corresponding to the first CSI-RS to a first network device.

[0024] Using the above method helps to identify the beam (i.e., the second beam) that has strong interference against the first terminal device. This facilitates subsequent information exchange between the first network device and the second network device regarding the strong interference beam. The second network device can determine which terminal devices used these beams when scheduling them and feed back the sequence of the first reference signal (i.e., the first sequence) used when scheduling the second terminal device to the first network device, thereby enabling the first network device to obtain the first sequence and improving the accuracy of interference measurement.

[0025] Secondly, embodiments of this application provide an information measurement method, which can be applied to the network side, such as network devices, modules (e.g., circuits, chips, or chip systems) within the network devices, or logical nodes, logical modules, or software capable of implementing all or part of the functions of the network devices. Taking the application of this method to a first network device as an example, in this method:

[0026] The first network device sends first configuration information to the first terminal device. The first configuration information is used to configure a first sequence to be measured. The first terminal device accesses the first cell. The first sequence is a sequence of first reference signals used by at least one second terminal device in the second cell.

[0061] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application.

[0064] To better understand the embodiments of this application, the communication system involved in the embodiments of this application will be described below:

[0065] The method provided in this application can be applied to various communication systems, such as: wireless local area network (WLAN) communication systems, wireless fidelity (Wi-Fi) systems, multiple-in multiple-out (MIMO) communication systems, long-term evolution (LTE) systems, internet of things (IoT) systems, narrowband internet of things (NB-IoT) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, fourth-generation (4G) systems, fifth-generation (5G) systems, or new radio (NR) systems, and other future communication systems, such as sixth-generation (6G) systems. Among these, IoT networks may include, but are not limited to, vehicle-to-everything (V2X) networks. The communication methods in V2X systems can be collectively referred to as vehicle-to-everything (V2X), where X can represent anything. For example, V2X can include vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, or vehicle-to-network (V2N) communication. The method provided in this application also supports communication systems that integrate multiple wireless technologies. For example, it can be applied to systems that integrate non-terrestrial networks (NTN) with terrestrial mobile communication networks, such as drones, satellite communication systems, and high-altitude platform station (HAPS) communication.

It is understood that the system architecture described in this application is for the purpose of more clearly illustrating the technical solutions of this application and does not constitute a limitation on the technical solutions provided in this application.

[0066] Figure 1 is a schematic diagram of the architecture of a communication system applicable to embodiments of this application. The communication system includes at least one network device and at least one terminal device. Figure 1 uses multiple network devices (such as a first network device and a second network device) and multiple terminal devices (such as a first terminal device, a second terminal device, and a third terminal device) as examples.

These terminal devices are also capable of communicating with the network device.

[0067] These terminal devices can access different cells (the cell a terminal device accesses is its serving cell), and network devices can manage the corresponding cells. In a wireless communication network, a cell refers to a wireless communication service area covering a specific geographical region. Each cell can be provided with wireless signal coverage and communication services by a corresponding network device. For example, as shown in Figure 1, the first terminal device accesses the first cell, and the first network device manages the first cell; the second and third terminal devices access the second cell, and the second network device manages the second cell. Of course, the number of terminal devices and network devices in Figure 1 is just an example, and there can be fewer or more. The terminal devices and network devices involved in the communication system in Figure 1 will be described in detail below.

[0068] I. Terminal Equipment

[0069] The terminal device mentioned in the embodiments of this application can be a device with wireless transceiver capabilities. The terminal device can communicate with access network equipment (or access devices or network devices) in a radio access network (RAN). The terminal device can also be referred to as user equipment (UE), access terminal, terminal, subscriber unit, user station, mobile station, remote station, remote terminal, mobile device, user terminal, user agent, or user device, etc. In one possible implementation, the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; or it can be deployed on water, including ships; or it can be deployed in the air, such as on airplanes, balloons, or satellites. In another possible implementation, the terminal device can be a handheld device with wireless communication capabilities, vehicle-mounted device, wearable device, sensor, terminal in the Internet of Things, terminal in the Internet of Vehicles, drone, 5G network, or any form of terminal device in future networks, etc., and this application embodiment does not limit this. In another possible implementation, the terminal device can also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in autonomous driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, or a wireless terminal in a smart home, etc.

[0070] In this application embodiment, the device for implementing the functions of the terminal device can be the terminal device itself; it can also be a device capable of supporting the terminal device in implementing the functions, such as a chip system. The device can be installed in the terminal device or used in conjunction with the terminal device. In this application embodiment, the chip system can be composed of chips or can include chips and other discrete devices. For ease of description, when examples are mentioned below, the technical solutions provided in this application embodiment are described using the UE as an example to illustrate the device for implementing the functions of the terminal device.

[0071] II. Network Equipment

[0072] The network device mentioned in this application embodiment can be a device deployed in a radio access network to provide wireless communication services to terminal devices. This network device can also be referred to as an access network device, access equipment, RAN node, or RAN device, etc. Exemplarily, the network device can be a base station, an evolved NodeB (eNodeB), a next-generation NodeB (gNB), a next-generation evolved NodeB (ng-eNB), or a network device in 6G communication, etc. The network device can be any device with wireless transceiver capabilities, including but not limited to the base stations shown above (including base stations deployed on satellites). The network device can also be a device with base station functionality in 6G. As an example, the network device can be an access node, wireless relay node, or wireless backhaul node in a wireless-fidelity (Wi-Fi) system. As another example, the network device can be a wireless controller in a cloud radio access network (CRAN) scenario. As yet another example, the network device can be a wearable device or in-vehicle device capable of providing wireless communication services, etc. As another example, the network device can also be a small station, a transmission reception point (TRP) (or a transmission point), etc. The network device can also be a master station, a secondary station, a motor slide retainer (MSR) node, a home base station, an access point (AP), a baseband unit (BBU), a remote radio unit (RRU), an active antenna unit (AAU), a remote radio head (RRH), a central unit (CU), a distributed unit (DU), a radio unit (RU), a positioning node, etc. In systems using different wireless access technologies, the names of devices with network device functions may vary; these will not be listed individually in the embodiments of this application.

[0073] Network devices can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile network device, and one or more cells can move according to the location of the mobile network device. In other examples, a helicopter or drone can be configured to be used as a device to communicate with another network device.

[0074] In some network device deployments, network devices can include centralized units (CUs) and distributed units (DUs). For example, some protocol layer functions of the network device may be centrally controlled by the CU, while the remaining partial or complete protocol layer functions may be distributed across the DU, which is then centrally controlled by the CU. In other network device deployments, the CU can be divided into CU-control plane (CP) and CU-user plane (UP). In still other deployments, the network device can also be an open radio access network (ORAN / O-RAN) architecture. When the network device is in an ORAN architecture, it can be a functional entity or module within the ORAN, such as a combination of one or more of the following: CU, DU, or RU. In an ORAN system, the CU can also be called an open (O)-CU, the DU can be called an O-DU, the CU-CP can be called an O-CU-CP, and the CU-UP can be called an O-CU-UP, etc. The network device deployment methods listed herein are merely examples. As standard technologies evolve, network devices may have other deployment forms, and this application does not limit them.

[0075] In some deployments, multiple RAN nodes collaborate to assist terminals in achieving wireless access, with different RAN nodes each implementing a portion of the access network's functions. For example, a RAN node can be a CU, DU, CU-CP, CU-UP, or RU, etc. CUs and DUs can be configured separately or included in the same network element, such as a BBU. RUs can be included in radio frequency equipment or radio frequency units, such as RRUs, AAUs, or RRHs.

[0076] RAN nodes can support one or more types of fronthaul interfaces, each corresponding to a DU and RU with different functions. If the fronthaul interface between the DU and RU is a common public radio interface (CPRI), the DU is configured to implement one or more baseband functions, and the RU is configured to implement one or more radio frequency functions. If the fronthaul interface between the DU and RU is another type of interface, relative to CPRI, some downlink and / or uplink baseband functions, such as, for downlink, precoding, digital beamforming (BF), or one or more of inverse fast Fourier transform (IFFT) / cyclic prefix addition (CP), are moved from the DU to the RU; and for uplink, one or more of digital beamforming (BF), or fast Fourier transform (FFT) / cyclic prefix removal (CP), are moved from the DU to the RU. In one possible implementation, the interface can be an enhanced common public radio interface (eCPRI). Under the eCPRI architecture, the segmentation between DU and RU differs, corresponding to different categories (Cat) of eCPRI, such as eCPRI Cat A, B, C, D, E, F.

[0077] Taking eCPRI Cat A as an example, for downlink transmission, layer mapping is used as the dividing line. DU is configured to implement one or more functions preceding layer mapping (i.e., coding, rate matching, scrambling, modulation, and layer mapping), while other functions following layer mapping (e.g., resource element (RE) mapping, digital beamforming (BF), or one or more inverse fast Fourier transform (IFFT) / cyclic prefix (CP) addition) are moved to RU. For uplink transmission, de-RE mapping is used as the dividing line. DU is configured to implement one or more functions preceding de-mapping (i.e., decoding, rate matching de-matching, descrambling, demodulation, inverse discrete Fourier transform (IDFT), channel equalization, and de-RE mapping), while other functions following de-mapping (e.g., digital BF or fast Fourier transform (FFT) / CP removal) are moved to RU. It is understandable that the functional descriptions of the DU and RU corresponding to various types of eCPRI can be found in the eCPRI protocol, and will not be elaborated here.

[0078] In one possible design, the processing unit in the BBU used to implement baseband functions is called the baseband high (BBH) unit, and the processing unit in the RRU / AAU / RRH used to implement baseband functions is called the baseband low (BBL) unit.

[0079] 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. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0080] In this application embodiment, the device for implementing the function of the network device can be the network device itself; it can also be a device capable of supporting the network device in implementing the function, such as a chip system. The device can be installed in the network device or used in conjunction with the network device. For ease of description, when specific examples are mentioned below, the technical solution provided in this application embodiment will be described using a base station as an example.

[0081] Network devices and / or terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located. Furthermore, terminal devices and network devices can be hardware devices, or software functions running on dedicated hardware or general-purpose hardware, such as virtualization functions instantiated on a platform (e.g., a cloud platform), or entities that include dedicated or general-purpose hardware devices and software functions. This application does not limit the specific form of the terminal devices and network devices.

[0082] It should be noted that the network application architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of network application architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0083] To facilitate understanding of the solutions provided in the embodiments of this application, the relevant concepts involved in the embodiments of this application are introduced below:

[0084] 1. Antenna Port

[0085] An antenna port is a logical concept; there is no direct correspondence between an antenna port and a physical antenna. An antenna port is typically associated with a reference signal, and its meaning can be understood as a transmit / receive interface on the channel through which the reference signal passes. Therefore, in some cases, an antenna port can also be a reference signal port or a pilot port. For low-frequency systems, an antenna port may correspond to one or more antenna elements that jointly transmit the reference signal; the receiver can treat them as a whole without distinguishing between individual elements. For high-frequency systems, an antenna port may correspond to a beam; similarly, the receiver only needs to treat this beam as an interface and does not need to distinguish between individual elements.

[0086] 2. Beam

[0087] In the NR protocol, beaming can be represented as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, QCL indication, etc. Beaming can be indicated by transmission configuration indication state (TCI-state) parameters or by spatial relation parameters. Therefore, in this application, beaming can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (DL TCI-state, UL TCI-state), spatial relation, etc. These terms are also equivalent to each other. Beaming can also be replaced with other beaming terms, which are not limited in this application.

[0088] The beam used to transmit signals can be called the transmission beam (Tx beam), or it can be referred to as a spatial domain transmission filter, spatial transmission filter, spatial domain transmission parameter, spatial transmission setting, or spatial transmission setting. The downlink transmission beam can be indicated by TCI-state.

[0089] The beam used to receive signals can be called a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception setting, or a spatial reception setting. The uplink transmit beam can be indicated by a spatial relation, an uplink TCI-state, or an SRS resource (indicating the transmit beam using that SRS). Therefore, the uplink beam can also be replaced by an SRS resource.

[0090] A transmit beam refers to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while a receive beam refers to the distribution of signal strength in different directions in space of the wireless signal received from the antenna. Beams generally correspond to resources. For example, during beam measurement, network devices measure different beams using different resources, and the terminal devices provide feedback on the measured resource quality, allowing the network devices to determine the quality of the corresponding beam. During data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the TCI field in downlink control information (DCI) to indicate the downlink shared channel (PDSCH) beam information of the terminal devices.

[0091] Optionally, multiple beams with the same or similar communication characteristics can be considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and reference signals, etc. One or more antenna ports forming a beam can also be considered as a set of antenna ports. In this embodiment, unless otherwise specified, a beam refers to the transmit beam of a network device. In beam measurement, each beam of a network device corresponds to a resource, and therefore the beam corresponding to that resource can be uniquely identified by the resource index. Furthermore, a beam can be a wide beam, a narrow beam, or other types of beams. The beamforming technique can be beamforming technology or other techniques. Beamforming technology refers to adjusting the amplitude and / or phase of a signal so that the radiated signal radiated through an antenna array has a certain directionality, enabling higher antenna array gain. The main lobe of the radiation pattern of the antenna array can be called a beam. Specifically, beamforming technology can be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc.

[0092] In beamforming technology, the amplitude and / or phase of a signal are adjusted after being filtered by a spatial domain transmission filter. Different spatial domain transmission filters using different spatial filtering parameters can achieve beams in different directions. In the embodiments of this application, the spatial filtering parameters can be replaced by beams, or the spatial filtering parameters can be replaced by spatial domain transmission filters. Spatial domain transmission filters can also be called spatial filters. Specifically, beamforming technology includes digital beamforming (DBF), analog beamforming (ABF), and hybrid digital-analog beamforming (HBF). DBF technology has multiple digital processing channels, each adjusting the phase (or amplitude and phase) of the signal in the digital domain, making the radiated signal through the antenna directional. Therefore, for DBF technology, the function of the aforementioned spatial domain transmission filter can be achieved through multiple digital processing channels. ABF (Alternating Aspect Ratio) technology can transmit signals simultaneously using an antenna array composed of multiple antenna elements. Each antenna element corresponds to a phase shifter. By adjusting the phase of the phase shifter corresponding to each antenna element, the radiated signal through the antenna array is made directional. Therefore, for ABF technology, the function of the aforementioned spatial transmission filter can be achieved through multiple phase shifters corresponding to multiple elements in the antenna array. HBF (Hybrid Beamforming) technology is a combination of ABF and DBF technologies, possessing both multiple digital processing channels and multiple analog phase shifters. Therefore, for hybrid beamforming technology, the function of the aforementioned spatial transmission filter can be achieved through multiple phase shifters corresponding to multiple elements in the antenna array and multiple digital processing channels. However, this application is not limited to this; the aforementioned spatial transmission filter can also be implemented using other technologies.

[0093] It is understandable that one or more antenna ports that form a beam can be regarded as an antenna port set or an antenna port group. For ease of description, the following text will uniformly refer to a beam formed by one antenna port, and one or more digital ports that form a beam are called a port group.

[0094] 3. Reference signal

[0095] According to the LTE / NR protocol, at the physical layer, uplink communication includes the transmission of uplink physical channels and uplink signals. Uplink physical channels include the random access channel (PRACH), physical uplink control channel (PUCCH), and physical uplink shared channel (PUSCH), etc. Uplink signals include channel sounding signals (SRS), uplink control channel demodulation reference signals (PUCCH-DMRS), uplink data channel demodulation reference signals (PUSCH-DMRS), uplink phase noise tracking reference signals (PTRS), uplink positioning signals (RS), etc. Downlink communication includes the transmission of downlink physical channels and downlink signals. The downlink physical channels include the physical broadcast channel (PBCH), the physical downlink control channel (PDCCH), and the physical downlink shared channel (PDSCH). The downlink signals include the primary synchronization signal (PSS) / secondary synchronization signal (SSS), the downlink control channel demodulation reference signal PDCCH-DMRS, the downlink data channel demodulation reference signal PDSCH-DMRS, the phase noise tracking signal PTRS, the channel status information reference signal (CSI-RS / CSIRS), the cell reference signal (CRS) (not present in NR), the time / frequency tracking reference signal (TRS) (not present in LTE), and the LTE / NR positioning signal (positioning RS).

[0096] Reference signals can be used for channel measurement, channel estimation, or beam quality monitoring. Depending on the LTE or NR protocol, uplink reference signals may include, for example, sounding reference signals (SRS), PUCCH-DMRS, PUSCH-DMRS, PTRS, uplink positioning RS, etc.; downlink reference signals may include, for example, synchronization signal blocks (SSB), physical downlink control channel (PDCCH)-demodulation reference signals (PDCCH-DMRS), PDSCH-DMRS, PTRS, CSI-RS, CRS, time / frequency domain tracking reference signals (TRS) in NR, and downlink positioning RS, etc.

[0097] 4. Synchronization Signal Block (SSB)

[0098] The synchronization signal block, also known as the synchronization signal and physical broadcasting channel block (SS / PBCH block), is one of the most important pilot channels used in 5G networks. Its function is related to many aspects of UE access to the cell, such as cell search, beam measurement, beam selection, and beam recovery. Network devices can periodically broadcast different SSBs in different communication areas, and these different SSBs can be distinguished by their indexes.

[0099] 5. Channel State Information Reference Signal (CSI-RS)

[0100] CSI-RS is an important channel state information reference signal in 5G networks, used for measuring wireless channel quality and performing beamforming operations. CSI-RS is transmitted at the physical layer using predefined resource elements, which are allocated to the receiving device for measuring channel quality and providing feedback. CSI-RS transmission employs orthogonal frequency division multiplexing (OFDM) technology, improving transmission efficiency by dividing the channel in the frequency and time domains. Upon receiving the CSI-RS, the receiving device measures the channel and calculates feedback information, sending feedback on channel quality, such as channel gain and phase, back to the transmitting device. The transmitting device then optimizes its transmission beam based on the feedback information from the receiving device to improve channel transmission efficiency and reliability.

[0101] In summary, CSI-RS provides important channel state information for 5G networks, enabling the network to dynamically adjust and optimize based on real-time channel conditions, thereby achieving more efficient and reliable wireless communication.

[0102] 6. Deterministic transmission

[0103] Deterministic transmission refers to ensuring predictable latency and jitter in network communication to meet the needs of time-sensitive applications. This transmission method is crucial for scenarios such as remote surgery, industrial automation, and autonomous driving, as these applications require data transmission latency and jitter to be kept within acceptable ranges to ensure operational safety and accuracy. Traditional communication networks typically employ a "best-effort" transmission mechanism, which leads to uncontrollable end-to-end latency and jitter, resulting in a long-tail effect in latency distribution. With the development of network services, more and more applications require end-to-end deterministic quality of service guarantees. For example, in remote surgery, any latency or jitter can lead to surgical failure; in industrial automation, latency and jitter can affect the efficiency and safety of production lines.

[0104] Similarly, deterministic services refer to services that are sensitive to network latency and require high bandwidth, high reliability, and low latency. Generally, deterministic services need to guarantee certain speed, latency, reliability, and user satisfaction requirements. Therefore, the network needs more resources than traditional "best-effort services" (i.e., services that do not guarantee latency, reliability, etc.) to support deterministic services.

[0105] To achieve deterministic transmission, researchers have developed various techniques, including time-sensitive networking (TSN) and deterministic networking (Detnet). These techniques, through methods such as optimizing network architecture, packet scheduling, network automation, and intelligence, can provide predictable quality of service.

[0106] In 5G mobile communications, the application of deterministic transmission technology is also crucial. Through technologies such as network slicing and end-to-end latency optimization, 5G networks can provide low-latency, high-reliability communication services, supporting the needs of deterministic services. This makes 5G the technological foundation for supporting applications in these fields, such as the Industrial Internet and the Internet of Vehicles. In summary, deterministic transmission technology is essential for supporting the development of time-sensitive applications. By providing predictable network service quality, it ensures the stability and reliability of data transmission, providing strong support for future network communications.

[0107] 7. Multiple-input multiple-output (MIMO) and downlink precoding

[0108] MIMO and downlink precoding are key technologies for ensuring deterministic transmission. MIMO technology refers to using multiple transmit and receive antennas at both the transmitting and receiving ends, allowing signals to be transmitted and received through these antennas, thereby improving communication quality. It makes full use of spatial resources, achieving multiple transmissions and receptions through multiple antennas, and can multiply the system channel capacity without increasing spectrum resources or antenna transmit power.

[0109] In 5G mobile communication, base stations are typically equipped with multiple antennas, each with a corresponding digital radio frequency (RF) link module. This allows the base station to freely adjust the signal transmitted by each antenna. Generally, due to the large number of RF links, the base station can arbitrarily adjust the amplitude and phase of the signal by adjusting the downlink precoding (also known as beam or weight) of the RF links of different antennas. This allows the transmitted signals from each physical antenna to coherently superimpose in a specific direction, while signals in other directions cancel each other out, forming a directional narrow beam. Narrow beams can suppress inter-beam interference and improve channel capacity and spectrum utilization through spatial multiplexing.

[0110] 8. Interference from neighboring cells

[0111] Downlink precoding (also known as beamforming) not only affects the determinism of transmission for UEs in the local cell, but also affects UEs in neighboring cells, causing interference with UEs in neighboring cells. This interference exhibits strong random fluctuation characteristics. It should be noted that the neighboring cell interference mentioned in this application embodiment refers to downlink neighboring cell co-channel interference, specifically the interference caused by signals transmitted from neighboring cells to UEs in the local cell.

[0112] From the perspective of a single UE, the maximum and minimum values ​​of neighboring cell interference at different times may even exceed 30 dB. As shown in Figure 2(a), when base station 2 sends a signal to UE2 in the second cell through the first beam, the interference to UE1 is strong because UE2 and UE1 in the first cell are in similar directions. As shown in Figure 2(b), when base station 2 sends a signal to UE3 in the second cell through the second beam, the interference to UE1 is weak because UE3 and UE1 in the first cell are in significantly different directions.

[0113] In traditional communication systems, the transmitting end can anticipate such sudden interference and mitigate its impact through methods such as hybrid automatic repeat request (HARQ) retransmission and pre-emptive modulation and coding scheme (MCS) reduction. However, for deterministic transmission, due to strong delay constraints, these methods easily lead to increased delays. Therefore, solutions in traditional communication systems are not suitable for deterministic transmission systems. Random fluctuations in interference are a crucial problem that must be addressed in deterministic transmission systems.

[0114] Currently, zero-power (ZP) CSI-RS can be used to assist UEs in measuring channel interference to neighboring cell base stations. ZP CSI-RS is a reference signal in 5G NR. Its difference from traditional CSI-RS lies in its "zero-power (ZP)" characteristic. This characteristic means that the base station does not transmit any power signal on the transmission resources of this reference signal. In other words, by configuring ZP CSI-RS, the base station assures the UE that the local base station remains silent on these resources. Thus, a UE configured with ZP CSI-RS can utilize these resources to measure interference from other cells. However, it is important to note that the ZP feature is transparent to the UE; that is, the UE is unaware that its own cell base station is transmitting ZP CSI-RS, and the CSI-RS it detects is transmitted by another base station.

[0115] Specifically, it mainly includes the following two steps:

[0116] Step 1: As shown in Figure 3A, base station 1 manages the first cell, base station 2 manages the second cell, and UE1 accesses the first cell. Base station 1 sends ZP CSI-RS, and base station 2 sends CSI-RS (at this time, this CSI-RS is also called non-zero power CSI-RS (i.e., NZP-CSI-RS)). UE1 in the first cell can use CSI-RS to measure the reference signal receiving power (RSRP) from itself to each port of base station 2. Alternatively, base station 2 sends SSB, and UE1 in the first cell can use SSB to measure the RSRP from itself to each port of base station 2. After measuring the neighboring cell CSI-RS or SSB, UE1 reports the RSRP of each port to base station 1.

[0117] Step 2: As shown in Figure 3B, UE2 accesses the second cell. Base station 2 calculates the beam precoding vector V2 for single-user (SU) scheduling of UE2 based on UE2's channel and sends V2 to base station 1. Base station 1 uses V2 and the RSRP of each port reported by UE1 to calculate the interference to UE1 from neighboring cells when scheduling UE2. For example, assuming the precoding vector... The RSRP obtained by base station 1 is: Where N t This refers to the number of antenna ports of the base station; therefore, when base station 2 schedules UE2, the interference to UE1 is as follows: This enables interference measurement.

[0118] However, as shown in Figure 4, if base station 2 is not serving UE2 as a single unit (SU), but rather as a multi-user (MU) unit simultaneously serving UE2 and UE3, then when base station 2 schedules UE2, in order to avoid intra-cell multi-user interference to UE3, it will adjust the precoding vector V2 of UE2, changing it from V2 to V3. This alters the interference to UE1 when base station 2 schedules UE2. UE1 cannot accurately measure this interference information, causing fluctuations in UE1's channel quality indicator (CQI), which in turn affects the deterministic transmission of deterministic services. Therefore, accurately measuring the interference from neighboring cells to the current cell to ensure the deterministic transmission of deterministic services is a pressing issue that needs to be addressed.

[0119] To accurately measure the interference from neighboring cells to a given cell, thereby ensuring the deterministic transmission of deterministic services, this application provides an information measurement method and a communication apparatus. The information measurement method and communication apparatus provided in the embodiments of this application are further described in detail below.

[0120] Figure 5 is a flowchart illustrating an information measurement method provided in an embodiment of this application. As shown in Figure 5, the information measurement method includes the following steps S501 and S502. Optionally, the information measurement method further includes step S503. The method execution entity shown in Figure 5 can be the first terminal device and the first network device mentioned above. Alternatively, the method execution entity shown in Figure 5 can be a chip in the first terminal device and a chip in the first network device; this embodiment of the application does not impose limitations. Figure 5 illustrates the method using the first terminal device and the first network device as examples of the method execution entities.

[0121] S501, the first network device sends first configuration information to the first terminal device. This first configuration information is used to configure a first sequence to be measured. The first terminal device accesses a first cell, and the first sequence is a sequence of first reference signals used by at least one second terminal device in a second cell. Correspondingly, the first terminal device receives the first configuration information from the first network device.

[0122] S502, The first terminal device measures the first reference signal according to the first sequence.

[0123] In this embodiment of the application, as shown in FIG4, taking a first terminal device and a second terminal device as examples, the first terminal device (i.e., UE1) accesses a first cell, and the first network device (i.e., base station 1) manages the first cell; the second terminal device (UE2) accesses a second cell, and the second network device (i.e., base station 2) manages the second cell. The second cell can be a neighboring cell of the first cell.

[0124] Suppose that the first reference signal used by the second network device when scheduling the second terminal device interferes with the first terminal device in the first cell. In this case, the second terminal device can be considered an interfering device targeting the first terminal device, and the first reference signal can be considered an interfering signal targeting the first terminal device. Here, the first reference signal can be a demodulation reference signal (DMRS). It should be noted that there is at least one second terminal device in the second cell; this explanation only uses one second terminal device as an example.

[0125] To enable the first terminal device to accurately measure interference information and ensure the deterministic transmission of deterministic services, the first network device can configure the first terminal device with the sequence of the first reference signal (i.e., the first sequence) used by the second network device when scheduling the second terminal device. Since the first reference signal is generated based on the first sequence, the first terminal device can separate the first reference signal from several signals based on the first sequence for measurement, thereby realizing interference measurement.

[0126] Specifically, the first network device can configure the first sequence to be measured using the first configuration information in two ways, which will be described in detail below. Of course, the first network device can also use other methods to configure the first sequence to the first terminal device, which are not limited here.

[0127] Method 1: The first configuration information includes the random seed used to generate the first sequence.

[0128] Taking DMRS as an example, the first network device uses the first configuration information to generate the random seed (i.e., C) used to generate the first sequence. init The first terminal device can then use its own DMRS sequence generation formula and the random seed (i.e., C) indicated by the first configuration information to generate the sequence. init The first sequence is generated. This first sequence is the DMRS sequence used by the second network device when scheduling the second terminal device in the second cell. This method indirectly configures the first sequence to the first terminal device, saving signaling overhead.

[0129] Method 2: The first configuration information includes the first sequence.

[0130] Taking DMRS as the first reference signal as an example, the first network device can directly instruct the first terminal device to use the first configuration information. Here, the first sequence is the DMRS sequence used by the second network device when scheduling the second terminal device in the second cell. This method allows the first sequence to be directly configured to the first terminal device, which helps reduce computational complexity and is convenient and fast.

[0131] In another possible implementation, the first configuration information may further include a first transmission resource or a first set of transmission resources. A specific implementation of the first terminal device measuring the first reference signal according to the first sequence may be: measuring the first reference signal according to the first sequence on the first transmission resource or the first set of transmission resources.

[0132] Specifically, assuming the first network device does not indicate to the first terminal device the specific transmission resources (i.e., the first transmission resources) occupied by the first reference signal, the first network device will configure a first set of transmission resources for blind detection for the first terminal device. The first terminal device can blindly detect the first reference signal on this first set of transmission resources. Specifically, the first terminal device detects the energy of the first sequence on all possible resource block (RB) locations, time-domain symbol locations, configuration types of the first reference signal, and orthogonal cover code (OCC) within the first set of transmission resources. When the detected energy is greater than a preset threshold, the first terminal device considers that the first reference signal has been detected on the current time-frequency resources.

[0133] Suppose the first network device indicates to the first terminal device the specific transmission resources (i.e., the first transmission resources) occupied by the first reference signal, then the first terminal device can directly measure the first reference signal on the first transmission resources according to the first sequence. This method allows the first terminal device to measure the first reference signal more accurately, without blind detection, thus saving power consumption.

[0134] The first transmission resource includes, but is not limited to, at least one of the following: the bandwidth occupied by the first reference signal (e.g., 100 RBs), the location of the resource block occupied by the first reference signal (e.g., RBs with indices 0-99), the location and number of time-domain symbols occupied by the first reference signal (e.g., time-domain symbols with index 0, time-domain symbols with index 1, or discrete sets of time-domain symbols with indices 0, 1, 4, and 5), the configuration type of the first reference signal (e.g., type 1 and type 2), the identifier of the antenna port used by the first reference signal, or the orthogonal code (OCC) used by the first reference signal.

[0135] Based on the above, the first network device needs to configure the first sequence to be measured to the first terminal device. Before configuring the first sequence to the first terminal device, the key issue is how the first network device obtains this first sequence. The following provides a detailed explanation of how the first network device obtains this first sequence.

[0136] Method 1: As shown in Figure 6A, it includes the following steps s21-s24.

[0137] s21. The first terminal device measures the second synchronization signal block of the second cell, and the energy of the second synchronization signal block is greater than or equal to the first threshold value.

[0138] s22. The first terminal device sends the identifier of the first beam corresponding to the second synchronization signal block to the first network device. Correspondingly, the first network device receives the identifier of the first beam from the first terminal device.

[0139] s23. The first network device sends the identifier of the first beam to the second network device. Accordingly, the second network device receives the identifier of the first beam from the first network device.

[0140] s24. The second network device sends a first sequence to the first network device based on the identifier of the first beam, wherein the first beam is the beam used by the second network device for the second terminal device in the second cell. Accordingly, the first network device receives the first sequence from the second network device.

[0141] Specifically, the first terminal device measures neighboring cell interference by periodically transmitting SSBs in the second cell. That is, it measures the SSBs of the second cell on the time-frequency resources where the second cell transmits SSBs, and obtains the energy (such as reference signal receiving power, RSRP) of each SSB in the second cell. Then, it determines whether the SSBs cause strong interference to the first terminal device based on a first threshold value.

[0142] The first threshold value can be predefined or configured by the first network device; this is not limited here. Optionally, the first threshold value is associated with the energy (e.g., RSRP) of the first synchronization signal block of the first cell. For example, the first threshold value is: (RSRP of the SSB of the first cell) -20dB. Assuming the measured RSRP of the SSB of the first cell is -100dBm, then the first threshold value is -120dBm; assuming the measured RSRP of the SSB of the first cell is -80dBm, then the first threshold value is -100dBm. This method improves the flexibility of setting the first threshold value.

[0143] If the RSRP of a certain SSB is greater than or equal to the first threshold value, it is considered that the SSB causes strong interference to the first terminal device; if the RSRP of a certain SSB is less than the first threshold value, it is considered that the SSB does not cause strong interference to the first terminal device.

[0144] Taking the second synchronization signal block of the second cell as an example, if the energy of the second synchronization signal block is measured to be greater than or equal to the first threshold value, it is considered that the second synchronization signal block causes strong interference to the first terminal device. The first terminal device needs to feed back the identifier of the first beam corresponding to the second synchronization signal block to the first network device.

[0145] For example, assuming the first threshold is -115dBm, the RSRP of the eight SSBs (i.e., SSB beam#0, SSB beam#1, SSB beam#2, SSB beam#3, SSB beam#4, SSB beam#5, SSB beam#6, and SSB beam#7) detected by the first terminal device in the second cell are -100dBm, -110dBm, -120dBm, -130dBm, -140dBm, -150dBm, -160dBm, and -170dBm, respectively. Among these, SSB beam#0 and SSB beam#1 are greater than the first threshold. Therefore, SSB beam#0 and SSB beam#1 cause strong interference to the first terminal device, and the first terminal device will feed back the identifiers of SSB beam#0 and SSB beam#1 (i.e., the identifiers of the first beams) to the first network device.

[0146] For example, the first threshold value is: (RSRP of the SSB of the first cell) -20dB. Assuming the RSRP of the SSB of the first cell is -100dBm, then the first threshold value is -120dBm. The first terminal device detects the RSRPs of the eight SSBs (i.e., SSB beam#0, SSB beam#1, SSB beam#2, SSB beam#3, SSB beam#4, SSB beam#5, SSB beam#6, and SSB beam#7) of the second cell as: -100dBm, -110dBm, -120dBm, -130dBm, -140dBm, -150dBm, -160dBm, and -170dBm, respectively. If SSB beam#0 and SSB beam#1 are greater than the first threshold value, and SSB beam#3 is equal to the first threshold value, then SSB beam#0, SSB beam#1 and SSB beam#3 will cause strong interference to the first terminal device. The first terminal device will feed back the identifiers of SSB beam#0, SSB beam#1 and SSB beam#3 (i.e. the identifiers of the first beam) to the first network device.

[0147] After the first network device obtains the identifier of the strong interference beam, it exchanges the identifier with the second network device; that is, the first network device sends the identifier of the first beam to the second network device. The second network device then determines which terminal devices will use the first beam when scheduling them. Assuming the second network device uses the first beam when scheduling a second terminal device, this second terminal device can be considered an interference device targeting the first terminal device. The second network device will then feed back the sequence of the first reference signal (i.e., the first sequence) used when scheduling the second terminal device to the first network device, allowing the first network device to obtain this first sequence.

[0148] Optionally, the method further includes: the second network device sending a first transmission resource to the first network device. Correspondingly, the first network device receives the first transmission resource from the second network device. This can be understood as the second network device indicating the specific transmission resource (i.e., the first transmission resource) occupied by the first reference signal to the first network device, so that the first network device can subsequently inform the first terminal device, enabling the first terminal device to measure the first reference signal more accurately without blind detection and saving power.

[0149] Method 2: As shown in Figure 6B, it includes the following steps s31-s34.

[0150] s31. The first terminal device measures the first CSI-RS, the energy of which is greater than or equal to the second threshold value.

[0151] s32. The first terminal device sends the identifier of the second beam corresponding to the first CSI-RS to the first network device. Correspondingly, the first network device receives the identifier of the second beam from the first terminal device.

[0152] s33. The first network device sends the identifier of the second beam to the second network device. Accordingly, the second network device receives the identifier of the second beam from the first network device.

[0153] s34. The second network device sends a first sequence to the first network device based on the identifier of the second beam, wherein the second beam is the beam used by the second network device for the second terminal device in the second cell. Accordingly, the first network device receives the first sequence from the second network device.

[0154] Specifically, the first terminal device measures neighboring cell interference using CSI-RS transmitted by the second cell. That is, the first network device configures ZP CSI-RS for the first terminal device, where the time-frequency resource location of the ZP CSI-RS is precisely the location where the second cell transmits CSI-RS (i.e., NZP CSI-RS). The first terminal device can measure the ZP CSI-RS on this time-frequency resource to obtain the energy (such as RSRP) of the second cell's CSI-RS. Then, it determines whether the CSI-RS causes strong interference to the first terminal device based on a first threshold value.

[0155] The first threshold value can be predefined or configured by the first network device, and is not limited here. If the RSRP of a certain CSI-RS is greater than or equal to the first threshold value, it is considered that the CSI-RS causes strong interference to the first terminal device; if the RSRP of a certain CSI-RS is less than the first threshold value, it is considered that the CSI-RS does not cause strong interference to the first terminal device.

[0156] Taking the first CSI-RS as an example, if the energy of the first CSI-RS is greater than or equal to the first threshold value, it is considered that the first CSI-RS causes strong interference to the first terminal device, and the first terminal device needs to feed back the identifier of the second beam corresponding to the first CSI-RS to the first network device.

[0157] For example, assuming the first threshold value is -115dBm, the RSRP of the first CSI-RS measured in the second cell is -100dBm. At this time, the RSRP of the first CSI-RS is greater than the first threshold value, so it is considered that the first CSI-RS causes strong interference to the first terminal device, and the first terminal device will feed back the identifier of the second beam corresponding to the first CSI-RS to the first network device.

[0158] After the first network device obtains the identifier of the strong interference beam, it exchanges the identifier with the second network device; that is, the first network device sends the identifier of the second beam to the second network device. The second network device then determines which terminal devices will use the second beam when scheduling them. Assuming the second network device uses the second beam when scheduling a second terminal device, this second terminal device can be considered an interference device targeting the first terminal device. The second network device will then feed back the sequence of the first reference signal (i.e., the first sequence) used when scheduling the second terminal device to the first network device, allowing the first network device to obtain this first sequence.

[0159] Optionally, the method further includes: the second network device sending a first transmission resource to the first network device. Correspondingly, the first network device receives the first transmission resource from the second network device. This can be understood as the second network device indicating the specific transmission resource (i.e., the first transmission resource) occupied by the first reference signal to the first network device, so that the first network device can subsequently inform the first terminal device, enabling the first terminal device to measure the first reference signal more accurately without blind detection and saving power.

[0160] Of course, after the first terminal device measures the first reference signal, it can further feed back the monitored interference statistics to the first network device so that the first network device can combine the interference statistics to configure more reliable transmission resources for the first terminal device and ensure the deterministic transmission of deterministic services.

[0161] Specifically, in one possible implementation, the method further includes step S503: the first terminal device sends interference statistics information to the first network device, the interference statistics information being determined based on the energy of the first reference signal. Correspondingly, the first network device receives the interference statistics information from the first terminal device.

[0162] This can be understood as follows: the first terminal device measures the first reference signal according to the first sequence, records and statistically analyzes the energy of the first reference signal, and the statistical information is the interference statistics. Optionally, the interference statistics include, but are not limited to, at least one of the following: the average energy of the first reference signal, the variance of the energy of the first reference signal, or the energy value corresponding to the first probability on the first probability distribution function. The first probability distribution function is the cumulative distribution function (CDF) corresponding to the energy of the first reference signal. The CDF is used to describe the cumulative distribution of a random variable. By reporting the interference statistics, the first terminal device enables the first network device to clearly understand the interference distribution of the first reference signal (i.e., the interference fluctuation range), so that the first network device can combine the interference statistics to configure more reliable transmission resources (such as a more robust modulation and coding scheme (MCS)) for the first terminal device, ensuring that deterministic services complete deterministic transmission within the time delay constraint.

[0163] The energy value corresponding to the first probability on the first probability distribution function can also be considered as the interference value corresponding to the first probability on the first probability distribution function. For example, assuming the first probability is X%, the interference statistics include the interference value corresponding to X% on the first probability distribution function. For instance, if X% is 90%, and the energy value corresponding to 90% on the first probability distribution function is YdBm, it means that 90% of the interference values ​​are less than YdBm, and the other 10% of the interference values ​​are greater than YdBm. This approach helps base stations select more robust MCS (Multi-Segment Control System), thereby improving transmission reliability.

[0164] It should be noted that the first probability (e.g., X%) here is the deterministic transmission confidence level configured by the first network device for the first terminal device. For example, this first probability can be configured by the first network device for the first terminal device through first configuration information, meaning that the first configuration information also includes the first probability. Alternatively, the first probability can also be configured by the first network device for the first terminal device through second configuration information; that is, before the first terminal device measures the first reference signal and calculates the interference statistics, the first network device can send second configuration information to the first terminal device, which includes the first probability; correspondingly, the first terminal device receives the second configuration information from the first network device.

[0165] In one possible implementation, the method further includes: a first network device predicting the distribution of the signal-to-interference plus noise ratio (SINR) within a first time period based on the interference statistics; and then configuring transmission resources for the first terminal device based on the SINR distribution.

[0166] This can be understood as follows: after receiving the interference statistics information fed back by the first terminal device, the first network device can predict the distribution of SINR in the first time period based on the interference statistics information. Based on the predicted SINR distribution, it can configure transmission resources that can guarantee latency constraints for the first terminal device, such as robust MCS, thereby ensuring the deterministic transmission of deterministic services.

[0167] As can be seen, based on the method described in Figure 5, taking the first terminal device and the second terminal device as examples, the first terminal device accesses the first cell, and the first network device manages the first cell; the second terminal device accesses the second cell, and the second network device manages the second cell. The second cell can be a neighboring cell of the first cell. The first reference signal used by the second network device when scheduling the second terminal device will interfere with the first terminal device in the first cell. Therefore, the second terminal device can be considered an interfering device targeting the first terminal device, and the first reference signal can be considered an interference signal targeting the first terminal device. The first network device can configure the sequence of the first reference signal (i.e., the first sequence) used by the second network device when scheduling the second terminal device to the first terminal device. Since the first reference signal is generated based on the first sequence, the first terminal device can separate the first reference signal from several signals based on the first sequence for measurement. This allows the first terminal device to more accurately measure the interference from neighboring cells to its own cell, so that the first network device can subsequently configure transmission resources that guarantee latency constraints for the first terminal device based on the interference distribution (i.e., interference fluctuation range), such as the more robust MCS, thereby ensuring deterministic transmission of deterministic services.

Optionally, at least one of the aforementioned memories may be included in the processing circuitry.

[0208] This application embodiment does not limit the specific connection medium between the transceiver circuit 810, processing circuit 820, and memory 830. In this application embodiment, the memory 830, processing circuit 820, and transceiver circuit 810 are connected by a bus 840 in Figure 8. The bus is represented by a thick line in Figure 8. The connection methods between other components are only for illustrative purposes and are not intended to be limiting. The bus can be divided into address bus, data bus, control bus, etc. For ease of illustration, only one thick line is used in Figure 8, but this does not mean that there is only one bus or one type of bus.

When data needs to be transmitted wirelessly, the processing circuit 820 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency (RF) circuit. The RF circuit then performs RF processing on the baseband signal and transmits the RF signal outward in the form of electromagnetic waves through the antenna. When data is sent to the device, the RF circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processing circuit 820.
