Description

Technical Field

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

[0002] With the development of wireless communication, high-frequency bands, such as millimeter-wave bands, with larger available bandwidth, have become important bands in modern communication systems. On the other hand, modern communication systems typically use multi-antenna technology to improve system capacity and coverage, thereby enhancing user experience. Using high-frequency bands can significantly reduce the size of multi-antenna configurations, facilitating site acquisition and the deployment of more antennas. However, high-frequency bands lead to greater path loss, especially as atmospheric and vegetation factors further exacerbate wireless propagation losses.

[0003] To overcome propagation loss caused by high-frequency bands, a signal transmission mechanism based on beamforming (BF) technology is employed to compensate for signal loss during propagation through a larger antenna gain. The beamformed signals can include broadcast signals, synchronization signals, and cell-specific reference signals, among others.

[0004] When signals are transmitted using beamforming technology, if a user moves, the direction of the beam corresponding to the transmitted signal may no longer match the user's new location, leading to frequent signal interruptions. To track changes in the beamforming beam during signal transmission, a channel quality measurement and result reporting method based on beamforming technology has been introduced. Channel quality measurement can be achieved based on the beamformed synchronization signal or a cell-specific reference signal.

[0005] As frequency bands increase and antenna size expands, the coverage area of ​​a beam decreases, leading to a significant increase in the number of beams that need to be scanned. This, in turn, greatly increases the overhead of beam scanning under traditional beam management frameworks. Therefore, a suitable management scheme is needed to achieve dynamic indication of the reference signal after beamforming, thereby improving system performance. Summary of the Invention

[0006] This application provides a communication processing method, apparatus, chip, and storage medium. Based on the method described in this application, the TCI state of a reference signal and / or the reference signal can be indicated based on indication information, making the indication of the reference signal more flexible and helping to reduce beam scanning overhead.

[0007] In a first aspect, this application provides a communication processing method applied to a terminal device. The method includes: receiving first downlink control information (DCI) from a network device, the first DCI including a first indication, the first indication being used to trigger the reporting of a first aperiodic channel state information (CSI) report, the first aperiodic CSI report being associated with a reference signal set; the first DCI further including a second indication and / or a third indication, wherein the second indication is used to indicate one or more reference signals in the reference signal set, and the third indication is used to indicate one or more TCI states in a transmission configuration indication (TCI) state set associated with the reference signals; and sending a measurement report to the network device measuring the reference signals based on the second indication and / or the third indication.

[0008] Based on the method described in the first aspect, the terminal device can obtain the reference signal to be monitored by receiving the second instruction, and / or obtain the TCI state associated with the reference signal by receiving the third instruction. Based on this, the network device can flexibly instruct the terminal device on the reference signal, so that the terminal device does not need to monitor additional reference signals. Furthermore, since the TCI state contains "Quasi Co-Location (QCL) Type D", i.e., spatial correlation information, the terminal device only needs to monitor the reference signal in the corresponding beam, and does not need to detect all beams, which helps to reduce system overhead and promote system performance improvement.

[0009] In one possible implementation, the second indication includes first bit information that corresponds to one or more reference signals in the set of reference signals.

[0010] Based on this implementation method, indications about the reference signal can be achieved through bit information. It is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0011] In one possible implementation, the first bit information includes: a bitmap, an index, a codepoint, or a pattern.

[0012] In one possible implementation, the bit width of the bitmap is the same as the number of reference signals in the reference signal set, and each bit of the bitmap includes a first value or a second value, the first value indicating that the corresponding reference signal will be sent, and the second value indicating that the corresponding reference signal will not be sent.

[0018] Based on this implementation, by using hierarchical indication, some information indicates a subset of reference signals, and some information indicates the corresponding reference signals in the subset. This helps to reduce indication overhead, save signaling resources, and enable flexible configuration of reference signals.

[0019] In one possible implementation, the second indication includes a sequence corresponding to a reference signal in the reference signal set.

[0020] Based on this implementation method, compatibility and scalability can be improved by combining it with sequences. By utilizing the correspondence between sequences and reference signals, signaling overhead can be reduced, control information can be simplified, and flexible configuration of reference signals can be achieved.

[0021] In one possible implementation, the sequence includes: the Zadoff-Chu sequence, the Gold sequence, or the m-sequence.

[0022] Based on this approach, efficient detection can be achieved by leveraging the strong correlation characteristics of Zadoff-Chu sequences, Gold sequences, or m sequences to determine the corresponding reference signal.

[0023] In one possible implementation, the third indication includes a second bit of information that corresponds to one or more TCI states in the TCI state set.

[0027] In one possible implementation, the index indicates the active TCI state in the TCI state set.

[0029] In one possible implementation, the pattern diagram indicates a combination of activated TCI states in the TCI state set.

[0030] Based on this implementation method, the indication of TCI status can be achieved through different methods such as bitmaps, indices, code points, or pattern patterns. It is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0031] In one possible implementation, the second and / or third indications may be carried in one or more of the following: broadcast messages; System Information Block (SIB); Common Control Messages; Downlink Control Information (DCI); Unlimited Resource Control (RRC) messages; and Media Access Control (MACCE) elements.

Based on this, the network device can flexibly instruct the terminal device on the reference signal, so that the terminal device does not need to monitor additional reference signals. Furthermore, since the TCI state contains "Quasi Co-Location (QCL) Type D", i.e., spatial correlation information, the terminal device only needs to monitor the reference signal in the corresponding beam, and does not need to detect all beams, which helps to reduce system overhead and promote system performance improvement.

Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. To better understand the embodiments of this application, the system architecture involved in the embodiments of this application is first introduced below:

[0083] Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. To facilitate understanding of the embodiments of this application, we will first use... Figure 1 The communication system illustrated herein is used as an example to describe in detail the communication system applicable to the embodiments of this application. It should be noted that the solutions in the embodiments of this application can also be applied to other mobile communication systems, and the corresponding names can be replaced by the names of the corresponding functions in other mobile communication systems.

[0085] This application describes various embodiments in conjunction with network devices and terminal devices, which can operate on licensed or unlicensed frequency bands, wherein:

[0086] Terminal devices include devices that provide voice and / or data connectivity to users. For example, a terminal device is a device with wireless transceiver capabilities that can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can be deployed in the air (such as on airplanes, balloons, and satellites). Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) terminals, augmented reality (AR) terminals, wireless terminals in industrial control, vehicle-mounted terminals, wireless terminals in self-driving vehicles, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wearable terminals, etc. The embodiments in this application do not limit the application scenarios.

[0087] By way of example and not limitation, in this embodiment, the terminal device can also be a wearable device. Wearable devices, also known as wearable smart devices, are a general term for devices that utilize wearable technology to intelligently design and develop everyday wearables, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not merely hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are feature-rich, large in size, and can achieve complete or partial functions without relying on a smartphone, such as smartwatches or smart glasses, as well as those that focus on a specific type of application function and require the use of other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0088] It is understood that, in the embodiments of this application, all or part of the functions of the terminal device can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (e.g., a cloud platform). The terminal device in this application can be a 5G terminal or a 6G terminal; this application does not limit this. In the embodiments of this application, the apparatus for implementing the functions of the terminal device can be the terminal device itself, or an apparatus capable of supporting the terminal device in implementing that function, such as a chip system or a combination of devices or components capable of implementing the functions of the terminal device, which can be installed in the terminal device.

[0089] Network devices can provide wireless access services to terminal devices; that is, network devices are access devices that enable terminal devices to access the communication system wirelessly. Network devices can be evolved Node Bs (eNBs or eNodeBs) in LTE; or base stations, broadband network gateways (BNGs), aggregation switches, or non-3GPP access devices in 5G networks, etc. This application does not specifically limit these categories. Network devices can also be referred to as access network devices, access nodes (ANs), radio access nodes (RANs), etc. For example, the base station in the embodiments of this application may include various forms of base stations, such as: macro base stations, micro base stations (also known as small stations), relay stations, access points, next-generation base stations (gNodeB, gNB), radio network controllers (RNC), node B (NB), base station controllers (BSC), base transceiver stations (BTS), home base stations (e.g., homeevolved nodeB, or home node B, HNB), base band units (BBU), transmitting and receiving points (TRP), transmitting points (TP), mobile switching centers, and devices that perform base station functions in device-to-device (D2D), vehicle-to-everything (V2X), machine-to-machine (M2M) communication, and Internet of Things (IoT) communication, etc. The embodiments of this application do not specifically limit these. Alternatively, network device 110 can also be a centralized unit (CU), a distributed unit (DU), a centralized unit control plane (CU-CP) node, or a centralized unit user plane (CU-UP) node.

[0090] Furthermore, in this embodiment, the network device provides services to a cell, and the terminal device communicates with the network device through the transmission resources (e.g., frequency domain resources, or spectrum resources) used by the cell. The cell can be a cell corresponding to a network device (e.g., a base station), and can belong to a macro base station or a base station corresponding to a small cell. Small cells here can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage area and low transmission power, making them suitable for providing high-speed data transmission services.

[0091] Furthermore, in LTE, NR, or future communication systems, multiple cells can operate simultaneously on the same frequency on a carrier. In certain special scenarios, the concepts of carrier and cell can be considered equivalent. For example, in carrier aggregation (CA) scenarios, when configuring a secondary carrier for a UE, the carrier index of the secondary carrier and the cell identifier (Cell ID) of the secondary cell operating on that secondary carrier are carried simultaneously. In this case, the concepts of carrier and cell can be considered equivalent; for instance, a UE accessing a carrier is equivalent to accessing a cell.

[0092] It is understood that in the embodiments of this application, the device used to implement the network device function can be the network device itself, or it can be a device that supports the network device in implementing the function, such as a chip system or a combination of devices or components that can implement the network device function. This device can be installed in the network device. The embodiments of this application do not limit the specific technology or specific device form used in the network device.

[0093] Unless otherwise specified, the higher-layer signaling in the embodiments of this application can refer to signaling issued by a higher-layer protocol layer, which is at least one protocol layer among all protocol layers above the physical layer. Specifically, the higher-layer protocol layer can be at least one of the following protocol layers: Medium Access Control (MAC) layer, Radio Link Control (RLC) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Resource Control (RRC) layer, and Non-Access Stratum (NAS) layer, etc. Higher-layer signaling can be signaling dedicated to a single terminal device, signaling shared by multiple terminal devices or a group of terminal devices, or signaling shared by all terminal devices within a cell.

[0094] Unless otherwise specified, in the embodiments of this application, physical layer signaling can be physical downlink control information, such as downlink control information (DCI), or other physical control information. It can be signaling specific to a single terminal device, such as physical layer signaling scrambled with a terminal device-specific identifier, physical layer signaling transmitted in a search space dedicated to the terminal device, or physical layer signaling transmitted in a control channel resource set dedicated to the terminal device. Alternatively, physical layer control signaling can be signaling shared by multiple terminal devices or a group of terminal devices, such as physical layer signaling scrambled with a group identifier, physical layer signaling transmitted in a search space shared by a group of terminal devices, or physical layer signaling transmitted in a control channel resource set shared by a group of terminal devices. Or, it can be signaling shared by all terminal devices within a cell. Alternatively, physical layer control signaling can be signaling shared by all terminal devices, such as physical layer signaling scrambled with an identifier shared by all terminal devices, physical layer signaling transmitted in a search space shared by all terminal devices, or physical layer signaling transmitted in a control channel resource set shared by all terminal devices.

[0095] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three cases: A exists alone, A and B exist simultaneously, and B exists alone.

For this purpose, the BBP is typically implemented in one or more digital signal processors (DSPs) within processor 201 or by a separate integrated circuit (IC).

[0100] Transceiver 202 can be used to support the transmission and reception of information between network devices and terminal devices. In the uplink, the uplink radio frequency signal from the terminal device is received via an antenna, modulated by transceiver 202, and the baseband signal is extracted and output to processor 201 for processing to recover the service data and / or signaling information sent by the terminal device. In the downlink, the baseband signal carrying the service data and / or signaling messages to be sent to the terminal device is modulated by transceiver 202 to generate the downlink radio frequency signal, which is then transmitted to the UE via an antenna. Transceiver 202 can include separate receiver and transmitter circuits, or they can be integrated into the same circuit to implement the transmission and reception functions.

[0101] The network device may also include a memory 203, which can be used to store the network device's program code and / or data.

[0102] The memory involved in the embodiments of this application can be a storage unit. Further details will not be provided below.

[0103] The network device may also include a communication unit 204 for supporting communication between the network device and other network entities. For example, it may support communication between the network device and network devices in the core network.

[0104] exist Figure 2 In the illustrated implementation, processor 201 can be coupled / connected to transceiver 202, memory 203, and communication unit 204, respectively. Alternatively, the network device may also include a bus. Transceiver 202, memory 203, and communication unit 204 can be connected to processor 201 via the bus. For example, the bus can be a Peripheral Component Interconnect (PCI) bus or an Extended Industry Standard Architecture (EISA) bus. The bus may include an address bus, a data bus, and a control bus.

This wireless communication device can be used as… Figure 1 The terminal devices 111 to 112 or the devices applied in the terminal devices 111 to 112. (Hereinafter referred to as...) Figure 3 The wireless communication device shown is an example of a terminal device. This terminal device is capable of executing the methods provided in the embodiments of the present invention. This terminal device may be... Figure 1 Either of the two terminal devices 111 to 112. The terminal device includes a transceiver 301, a memory 303, and a processor 304 for implementing wireless communication functions.

[0106] The processors involved in the embodiments of this application can be processing units, and the transceivers can be transceiver units. Further details will not be provided below.

[0107] Transceiver 301 can be used to support the transmission and reception of information between terminal devices and network devices. In the downlink, the downlink radio frequency signal from the network device is received via an antenna, modulated by transceiver 301, and the baseband signal is extracted and output to processor 304 for processing to recover the service data and / or signaling information transmitted by the network device. In the uplink, the baseband signal carrying the service data and / or signaling messages to be transmitted to the network device is modulated by transceiver 301 to generate the uplink radio frequency signal, which is then transmitted to the network device via an antenna. Transceiver 301 can include separate receiver and transmitter circuits, or they can be integrated into the same circuit to implement the transmission and reception functions.

[0108] Processor 304 may be a modem processor. Processor 304 may include a baseband processor (BBP) that processes the digitized received signal to extract the information or data bits carried in the signal. For this purpose, the BBP is typically implemented in one or more digital signal processors (DSPs) within processor 304 or by a separate integrated circuit (IC).

[0109] For example, such as Figure 3As shown, in one implementation of processor 304, processor 304 may include encoder 3041, modulator 3042, decoder 3043, and demodulator 3044. Encoder 3041 is used to encode the signal to be transmitted. For example, encoder 3041 can be used to receive service data and / or signaling messages to be transmitted on the uplink and process the service data and signaling messages (e.g., formatting, encoding, or interleaving). Modulator 3042 is used to modulate the output signal of encoder 3041. For example, modulator can perform symbol mapping and / or modulation on the encoder's output signal (data and / or signaling) and provide output samples. Demodulator 3044 is used to demodulate the input signal. For example, demodulator 3044 processes the input samples and provides symbol estimation. Decoder 3043 is used to decode the demodulated input signal. For example, decoder 3043 deinterleaves, and / or decodes the demodulated input signal and outputs the decoded signal (data and / or signaling).

[0110] Processor 304 receives digitized data that can represent voice, data, or control information, and processes this digitized data for transmission. Processor 304 can support one or more of various wireless communication protocols for multiple communication systems, such as Long Term Evolution (LTE), New Radio (NR), Universal Mobile Telecommunications System (UMTS), High Speed ​​Packet Access (HSPA), etc. Optionally, processor 304 may also include one or more memories.

[0111] The terminal device may also include an application processor 302 for generating the aforementioned digital data that can represent voice, data, or control information.

[0112] Processor 304 and application processor 302 can be integrated into a single processor chip.

[0113] The memory 303 is used to store program code (sometimes also called program, instruction, software, etc.) and / or data for supporting communication of terminal devices.

[0114] The memory involved in the embodiments of this application can be a storage unit. Further details will not be provided below.

[0115] It should be noted that memory 203 or memory 303 may include one or more storage units. For example, it may be a storage unit inside processor 201, processor 304 or application processor 302 for storing program code, or it may be an external storage unit independent of processor 201, processor 304 or application processor 302, or it may be a component that includes storage units inside processor 201, processor 304 or application processor 302 and external storage units independent of processor 201, processor 304 or application processor 302.

[0116] Processors 201 and 304 can be the same type of processor or different types of processors. For example, they can be implemented in a Central Processing Unit (CPU), a general-purpose processor, a Digital Signal Processor (DSP), an Application-Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other programmable logic devices, transistor logic devices, hardware components, other integrated circuits, or any combination thereof. Processors 201 and 304 can implement or execute various exemplary logic blocks, modules, and circuits described in conjunction with the disclosure of embodiments of this invention. Processors can also be combinations of devices that implement computing functions, such as combinations of one or more microprocessors, combinations of DSPs and microprocessors, or systems-on-a-chip (SoCs), etc.

[0117] Those skilled in the art will understand that the various illustrative logic blocks, modules, circuits, and algorithms described in connection with the aspects disclosed herein can be implemented as electronic hardware, instructions stored in memory or another computer-readable medium and executed by a processor or other processing device, or a combination of both. As an example, the devices described herein can be used in any circuit, hardware component, IC, or IC chip. The memory disclosed herein can be of any type and size and can be configured to store any type of information as required. To clearly illustrate this interchangeability, various illustrative components, blocks, modules, circuits, and steps have been generally described above in their functional form. How such functionality is implemented depends on the specific application, design choices, and / or design constraints imposed on the overall system. Those skilled in the art can implement the described functionality in different ways for each specific application, but such implementation decisions should not be construed as departing from the scope of the invention.

[0118] Before describing the technical solutions of the embodiments of this application, the relevant technical terms and application scenarios in the embodiments of this application will be explained and described first:

[0119] 1. Control resource set (CORESET)

[0120] CORESET: To improve the efficiency of blind detection control channels in terminals, the concept of control resource sets was introduced during the NR standard development process. Network devices can configure one or more resource sets for a UE to transmit the Physical Downlink Control Channel (PDCCH). Network devices can transmit control channels to the terminal on any control resource set corresponding to the terminal. In addition, network devices also need to notify the terminal of other associated configurations of the control resource set, such as the search space set. The configuration information for each control resource set differs, for example, in terms of frequency domain bandwidth and time domain length.

[0121] Optionally, the control resource set in this application may be a CORESET, control region, or ePDCCH set defined by a 5G mobile communication system.

[0122] 2. Quasi-collocation (QCL) information

[0123] QCL Information: Quasi-co-site / quasi-co-located QCL assumption information can also be called QCL information. QCL information is used to help describe the beamforming information and reception process on the receiving side of the terminal.

[0124] Furthermore, QCL information is used to indicate the QCL relationship between two reference signals: a source reference signal and a target reference signal. The target reference signal can generally be a demodulation reference signal (DMRS), a channel state information reference signal (CSI-RS), etc., while the referenced or source reference signal can generally be a CSI-RS, a tracking reference signal (TRS), a synchronous signal / PBCH block (SSB), etc. It should be understood that the spatial characteristic parameters of two reference signals or channels satisfying the QCL relationship are the same or similar, thus the spatial characteristic parameters of the target reference signal can be inferred based on the source reference signal resource index. These spatial characteristic parameters include one or more of the following:

[0125] Angle of arrival (AoA), dominant angle of arrival, average angle of arrival, power angular spectrum (PAS) of the angle of arrival, angle of departure (AoD), dominant angle of departure, average angle of departure, power angular spectrum of the angle of departure, terminal transmit beamforming, terminal receive beamforming, spatial channel correlation, base station transmit beamforming, base station receive beamforming, average channel gain, average channel delay, delay spread, Doppler spread, Doppler shift, spatial Rx parameters, etc.

[0126] These spatial characteristic parameters describe the spatial channel characteristics between the antenna ports of the source reference signal and the target reference signal, helping the terminal to complete receiver-side beamforming or reception processing based on this QCL information. It should be understood that the terminal can receive the target reference signal based on the reception information of the source reference signal indicated by the QCL information.

[0127] To reduce the overhead of QCL information indication from the network device side to the terminal side, one optional implementation is that the network device side can indicate that the demodulation reference signal of the Physical Downlink Control Channel (PDCCH) or Physical Downlink Shared Channel (PDSCH) satisfies a QCL relationship with one or more of the multiple reference signal resources previously reported by the terminal. For example, the reference signal can be a CSI-RS. Here, each reported CSI-RS resource index corresponds to a transmit / receive beam pair previously established based on the measurement of that CSI-RS resource. It should be understood that the receive beam information of the two reference signals or channels that satisfy the QCL relationship is the same, so that the UE can infer the receive beam information of the PDCCH or PDSCH based on the reference signal resource index.

[0128] The existing standard defines four types of QCL (Type A to Type D). The base station can configure one or more types of QCL for the UE at the same time, such as QCL type A+D or C+D:

[0129] QCL Type A: Doppler shift, Doppler spread, average channel delay, and delay spread;

[0130] QCL Type B: Doppler frequency shift and Doppler extension;

[0131] QCL type C: Average channel delay and Doppler shift;

[0132] QCL type D: Spatial Rx parameter.

[0133] Understandably, the QCL information in this application includes one or more of QCL types A, B, C, and D.

[0134] 3. Spatial relation information

[0135] Spatial-related information is used to assist in describing the beamforming information or transmission process on the transmitting side of the terminal. Specifically, spatial-related information indicates the spatial reception parameter relationship between two reference signals. The target reference signal can generally be a DMRS, a sounding reference signal (SRS), etc., while the referenced or source reference signal can generally be a CSI-RS, SRS, SSB, etc. It should be understood that the spatial characteristic parameters of the two reference signals or channels that satisfy the spatial-related information are the same, so the spatial characteristic parameters of the target reference signal can be inferred based on the source reference signal resource index. These spatial characteristic parameters are the same as those mentioned above, such as angle of arrival (AoA), dominant angle of arrival, average angle of arrival, etc., and spatial reception parameters (spatial Rx parameters), etc., which are not detailed here. These spatial characteristic parameters describe the spatial channel characteristics between the antenna ports of the source reference signal and the target reference signal, helping the terminal to complete the transmitting-side beamforming or transmission process based on the spatial-related information. It should be understood that the terminal can transmit the target reference signal based on the transmission information of the source reference signal indicated by the spatial-related information.

[0136] 4. Transmission Configuration Indicator / Indication (TCI)

[0137] TCI information: Used to indicate the QCL information of PDCCH / CORESET or PDSCH. Further, TCI information refers to the fact that the reference signal included in the TCI satisfies the QCL relationship with the DMRS of the PDCCH / PDSCH. It is mainly used to indicate that when receiving the PDCCH / PDSCH, its spatial characteristic parameters and other information are the same, similar, or nearly identical to the spatial characteristic parameters and other information of the reference signal included in the TCI.

[0138] 5. Synchronization Signal Broadcast Channel Block (SS / PBCH block)

[0139] The SS / PBCH block (synchronous signal / PBCH block) can also be called the SSB. PBCH stands for Physical Broadcast Channel. The SSB contains at least one of the primary synchronization signal (PSS), secondary synchronization signal (SSS), and PBCH. It is primarily used for cell search, cell synchronization, and carrying broadcast information.

[0140] 6. Beam

[0141] A beam is a communication resource. A beam can be wide, narrow, or other types. The technology used to form a beam can be beamforming or other techniques. Beamforming technology can specifically be digital beamforming, analog beamforming, or hybrid digital / analog beamforming. Different beams can be considered different resources; the same information or different information can be transmitted through different beams.

[0142] 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 detection signals, etc. For example, a transmit beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, and a receive beam can refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna. It is understood that one or more antenna ports forming a beam can also be considered as a set of antenna ports.

[0143] Beams can be divided into transmit beams and receive beams of network devices, and transmit beams and receive beams of terminals. The transmit beam of a network device, such as a base station, describes the beamforming information transmitted by the network device, while the receive beam of the base station describes the beamforming information received by the network device. Similarly, the transmit beam of a terminal describes the beamforming information transmitted by the terminal, and the receive beam describes the beamforming information received by the terminal. Therefore, broadly speaking, beams can be used to describe beamforming information.

[0144] In addition, beams can correspond to one or more of the following: time resources, spatial resources, and frequency domain resources.

[0145] Optionally, the beam can also correspond to a reference signal resource (e.g., a beamforming reference signal resource) or beamforming information.

[0146] Optionally, the beam can also correspond to information associated with a reference signal resource of the network device. The reference signal can be CSI-RS, SSB, DMRS, phase tracking reference signal (PTRS), TRS, etc., and the information associated with the reference signal resource can be a reference signal resource identifier, or QCL information (especially type D QCL), TCI information, etc. The reference signal resource identifier corresponds to a transmit / receive beam pair previously established based on measurements of that reference signal resource; the terminal can infer the beam information through this reference signal resource index.

[0147] Optionally, the beam can also correspond to a spatial filter, a spatial domain transmission filter, a space filter, and a space transmission filter. Specifically, the receiving beam is equivalent to a space transmission filter, a spatial domain transmission filter, a spatial receiving filter, and a space receiving filter; the transmitting beam can be equivalent to a spatial filter, a spatial domain transmission filter, a spatial transmitting filter, and a space transmitting filter. Information about space-related parameters is equivalent to a spatial domain transmission / receive filter.

[0148] Furthermore, a spatial filter generally includes a spatial transmit filter and / or a spatial receive filter. This spatial filter can also be referred to as a spatial transmit filter, a spatial receive filter, a spatial transmission filter, a spatial transmission filter, etc. Optionally, the receive beam on the terminal side and the transmit beam on the network device side can serve as a downlink spatial filter, and the transmit beam on the terminal side and the receive beam on the network device side can serve as an uplink spatial filter.

[0149] 7. Initial Bandwidth Part (Initial BWP)

[0150] When a terminal accesses a cell or a broadband carrier from an RRC idle state, the BWP at the time of initial access is called the initial BWP, or it can be understood as the terminal performing random access on the initial BWP.

[0151] 8. Activate BWP

[0152] When a service arrives at a terminal, the network device schedules the terminal from its initial BWP to a BWP with bandwidth matching its service. The network device can then instruct the terminal device on the active BWP via higher-layer signaling or layer-1 signaling. The terminal can then send and receive data and / or reference signals on this active BWP. This BWP is called the active BWP. In a single-carrier scenario or a single serving cell scenario, a terminal has only one active BWP at any given time, and the terminal can only receive or send data / reference signals on the active BWP.

[0153] Current communication systems support dynamic BWP handover. Network devices instruct terminal devices to hand over BWPs via downlink control information (DCI) or radio resource control (RRC) signaling. The DCI is located within the current BWP, and the size of its frequency domain resource allocation information field is determined by the bandwidth of the current BWP. The DCI contains a bandwidth part indicator field, which indicates the ID number of the BWP activated by the terminal. When the BWP ID number indicated by this field does not match the ID number of the currently activated BWP (i.e., the current BWP transmitting the DCI), the terminal needs to hand over from the current BWP to the BWP indicated in the DCI.

[0154] Currently, communication systems typically use different types of reference signals: one type is used for channel estimation, such as DMRS, which enables coherent demodulation of received signals containing control information or data; another type is used for channel state or channel quality measurement, such as CSI-RS, to achieve UE scheduling. The UE obtains channel state information (CSI) based on channel quality measurements using CSI-RS. CSI includes at least one of the following: Rank Indicator (RI), Precoding Matrix Indicator (PMI), and Channel Quality Indicator (CQI). This CSI information can be transmitted by the UE to the base station via the Physical Uplink Control Channel (PUCCH) or the Physical Uplink Shared Channel (PUSCH).

[0155] The existing methods for obtaining spatially relevant parameter information for PDSCH or PUSCH are as follows:

[0156] The indication of spatially relevant parameters / spatial characteristic parameters of PDSCH is mainly achieved through TCI information, such as through joint indication by Radio Resource Control (RRC) signaling, Medium Access Control (MAC-CE) signaling, and Downlink Control Information (DCI), or through joint indication by RRC signaling and DCI.

[0157] Specifically, an indication method may include:

[0158] First, the network device configures the M candidate Transmission Configuration Indicator (TCI) states of the PDSCH via RRC signaling. That is, the RRC message includes M candidate TCI state configuration information, and each candidate TCI state includes one QCL (Quality Class Query) information. Each TCI state configuration information includes a TCI ID. Furthermore, it may also include QCL type A and / or type B.

[0159] Then, the network device activates 2 from M TCI states via MAC-CE. N M TCI states (a subset of M TCI states).

[0160] Table 1 shows a schematic diagram of a MAC-CE format for indicating the activation or deactivation state of a TCI state field using MAC-CE.

[0161] Table 1

[0162]

[0163] The Bandwidth part (BWP) ID, which occupies 2 bits, is used to indicate the downlink bandwidth applied by the MAC-CE.

[0164] Serving cell ID (5 bits): Used to indicate the ID of the serving cell to which the TCI indicated by the MAC-CE belongs.

[0165] “R” represents the reserved bit, which is usually set to “0”.

[0166] The Ti field indicates the activation / deactivation of the TCI state with TCI state identifier i. Further, if the Ti field is "1", it means that the TCI state with TCI state identifier i is activated and mapped to the TCI field in the DCI. If the Ti field is "0", it means that the TCI state with TCI state identifier i is deactivated and is not mapped to the TCI field in the DCI.

[0167] In this MAC CE, all TCI states set to 1 are mapped sequentially to code points; that is, the first TCI state field set to 1 is mapped to code point value 0, the second TCI state field set to 1 is mapped to code point value 1, and so on. In the NR Rel-15 protocol, the maximum number of active TCI states is 8.

[0168] The TCI field in DCI has N bits used to indicate 2. N One of the TCI states is used for PDSCH reception. In the NR version 15 (Release 15) protocol, N=3. The DCI shown in Table 2 can be used to indicate one of the TCI states.

[0169] Table 2

[0170]

[0171]

[0172] For example, a network device uses RRC signaling to indicate 64 TCI states for PDSCH reception. MAC-CE signaling activates 8 of the 64 TCI states, with IDs a1 to a8. If one of the TCI states has a value of 000, the terminal device determines the corresponding TCI state ID as a1, and the terminal device receives the PDSCH according to the TCI state indicated by TCIstateId a1.

[0173] The presence of the TCI field of PDSCH in DCI can be indicated by higher-layer signaling, such as the TCI-PresentInDCI field in RRC signaling. This field can be configured for each CORESET. When a CORESET has this field configured and enabled, then the TCI field exists in the DCI detected by that CORESET. When a CORESET has not configured this field, then the TCI field does not exist in the DCI detected by that CORESET. In this case, optionally, the TCI state of PDSCH is the TCI state configured by PDCCH.

[0174] When the scheduling offset is less than the threshold k, the UE uses the default TCI state to receive the PDSCH; when the scheduling offset is greater than the threshold k, the UE uses the TCI state indicated in the DCI to receive the PDSCH. It is stipulated that during the initial RRC and MAC-CE phases, the UE assumes that the DMRS of the PDCCH and PDSCH are QCLs with the synchronous signal broadcast channel block (PBCH block, SSB) determined during initial access.

[0175] The beam information for indicating the spatial relation parameters / spatial characteristic parameters of PUSCH is similar to that of PDSCH. It can be indicated by a combination of RRC signaling, MAC-CE and DCI, or by RRC signaling and DCI. The DCI includes a sounding reference signal resource indicator (SRI) field, which is used to indicate the spatial relation information of PUSCH.

[0176] In some scenarios, network devices need to instruct terminal devices to measure specific reference signals and report the measurement results. Currently, CSI measurement reports triggered by DCI measure aperiodic triggering states pre-configured by RRC, with a maximum of 128 aperiodic triggering states. A single trigger can contain up to 16 CSI reports, thus triggering a maximum of 128 × 16 = 2048 states.

[0177] However, in practice, the combinations of reference signals used in current NR systems far exceed the support range of existing protocols. Specifically, existing NR protocols can support a set of 192 preset reference signals. Even with only a set of 32 reference signals configured, and the network device instructing the terminal device to use four specific reference signals from that set for measurement, issues still exist. Such combinations, for example, if a set of 64 reference signals is configured, and the network device instructs the terminal device to perform measurements on 4 specific reference signals from the set, then there exists C6. 4 There are 4 = 635,376 combinations, which far exceeds the support range of 2,048 states.

[0178] Figure 4 This is a flowchart illustrating a communication processing method provided in an embodiment of this application. Figure 4 As shown, the entity executing this communication processing method can be the terminal device and network device mentioned above. Alternatively, Figure 2 The device executing the method shown can be a chip in a terminal device or a chip in a network device; however, this application does not limit the implementation of such a method. Figure 2 The method will be explained using terminal devices and network devices as examples.

[0179] S401. The network device sends the first DCI to the terminal device. Correspondingly, the terminal device receives the first DCI from the network device.

[0180] The first DCI includes a first indication, which is used to trigger the reporting of a first aperiodic channel state information (CSI) report, which is associated with a reference signal set.

[0181] The first DCI further includes a second indication and / or a third indication, wherein the second indication is used to indicate one or more reference signals in the reference signal set, and the third indication is used to indicate one or more TCI states in the transmission configuration indication TCI state set associated with the reference signals.

[0182] The reference signal set can be pre-configured by the network device and notified to the terminal device, for example, by pre-configuring and notifying the terminal device via an RRC message. In this application, the total number of reference signals in the reference signal set is denoted as M, where M is a positive integer.

[0183] The TCI state set can be pre-configured by the network device and notified to the terminal device, for example, through an RRC message. In this application, the total number of TCI states in the TCI state set is denoted as N, where N is a positive integer.

[0184] The network device can send a second instruction to the terminal device to instruct the terminal device to monitor one or more reference signals in the reference signal set.

[0185] The network device can also send a third instruction to the terminal device, indicating one or more TCI states associated with the reference signal in the TCI state set, so that the terminal device can determine the corresponding beam of the reference signal based on the spatial information (e.g., QCL type D) in the TCI state.

[0186] In some embodiments, the network device may send a second instruction to the terminal device without sending a third instruction.

[0187] In some scenarios, reference signals and beams can be pre-configured, along with the corresponding TCI status information. This way, the network device only needs to indicate the reference signal to be transmitted to the terminal device, and the terminal device can then obtain the corresponding beam and TCI status. Optionally, this pre-configured information, i.e., the binding / correspondence, can be pre-configured via, for example, RRC messages.

[0188] Based on pre-configured binding / correspondence relationships, network devices can send a second instruction to terminal devices, indicating the reference signal to be sent, so that terminal devices can measure the corresponding reference signal and provide a measurement report.

[0189] In some embodiments, the second indication includes first bit information, which corresponds to one or more reference signals in the reference signal set.

[0190] A network device can send a second indication to a terminal device based on bit information, indicating one or more reference signals in a set of reference signals. In other words, the second indication sent by the network device to the terminal device may include first bit information, which may correspond to one or more reference signals in the set of reference signals, or in other words, the first bit information may indicate one or more reference signals in the set of reference signals.

[0191] In some embodiments, the first bit information may be a bitmap, the bit width of which is the same as the total number of reference signals in the reference signal set, and the bit width is M. It uses 1 or 0 to indicate whether the corresponding reference signal in the reference signal set will be sent or will not be sent.

[0192] For example, if the pre-configured reference signal set contains 8 reference signals and the first bit information is 01010101, it means that reference signals 2, 4, 6, and 8 in the reference signal set will be sent, while reference signals 1, 3, 5, and 7 will not be sent.

[0193] In some embodiments, the first bit information may be the index of K reference signals in the reference signal set, where K is a positive integer and K≤M. That is, the first bit information may include the indices of the K reference signals to be transmitted; therefore, the overall bit width of the first bit information is [value missing].

[0194] For example, if a pre-configured set of reference signals contains eight reference signals, the indices of these eight reference signals can be represented as 000, 001, 010, 011, 100, 101, 110, and 111, respectively. If the network device indicates to the terminal device that reference signals numbered 2, 4, 6, and 8 in the reference signal set will be transmitted, the first bit of information can be 001011101111.

[0195] Alternatively, the index of the reference signal can also be represented using a CSI-RS resource indicator (CRI) or an SSB resource indicator (SS / PBCH Block Resource indicator (SSBRI)).

[0196] In some embodiments, the first bit information may be the code points of K reference signals in the reference signal set.

[0197] Network devices and terminal devices can be pre-configured with a mapping relationship between reference signals and code points through a protocol. The network device can send code points corresponding to the reference signals to be sent to the terminal device to indicate these reference signals to be sent.

[0198] In some embodiments, the first bit information may be a pattern, which is predefined as indicating a combination of K reference signals in a set of reference signals, where K is a positive integer and K ≤ M. In other words, the pattern may be a bit-width... The bit information.

[0199] For example, when M=64 and K=4, In other words, 20 bits can represent all integers from 0 to 635375, meaning a 20-bit pattern can support 635376 possible combinations. For example, when the first bit is 0 (decimal), it can indicate that reference signal {1, 2, 3, 4} will be transmitted; when the first bit is 1 (decimal), it can indicate that reference signal {1, 2, 3, 5} will be transmitted, and so on. The combinations of reference signals represented by the pattern in this application are merely examples and not limitations. This application does not limit the correspondence between the pattern and the combinations of reference signals in the reference signal set.

[0200] Optionally, the mapping relationship between the pattern and the combination of K reference signals can be pre-configured, for example, by an RRC message, so that the network device and the terminal device can reach an agreement.

[0201] It is understandable that indicating the reference signal can be achieved through different methods such as bitmaps, indices, code points, or pattern patterns. This is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0202] In some embodiments, the first bit information includes a first sub-information and a second sub-information, wherein the first sub-information is used to indicate one or more reference signal subsets in the reference signal set, and the second sub-information is used to indicate one or more reference signals in the one or more reference signal subsets.

[0203] Network devices can indicate to terminal devices the reference signals to be transmitted based on a two-level indication method. In the two-level indication method, the reference signal set can be divided into multiple subsets. The first sub-information indicates the subsets in which reference signals will be transmitted, and the second sub-information indicates the reference signals to be transmitted within these subsets.

[0204] For example, the first sub-information in the first bit information can be the first bit map, and the second sub-information can be the second bit map.

[0205] The first bit diagram can be used to indicate which subsets of reference signals in the reference signal set will have reference signals transmitted. For example, if the reference signals in the reference signal set can be divided into 8 subsets, and the first bit diagram is 10101010, it means that reference signals in subsets 1, 3, 5, and 7 will be transmitted.

[0206] The second bitmap can be used to indicate which reference signals in each subset of reference signals will be transmitted. For example, if there are 8 reference signals in a subset of reference signals, and the second bitmap is 01010000, it means that the 2nd and 4th reference signals in each subset will be transmitted.

[0207] If we combine 10101010 in the first bitmap with 01010000 in the second bitmap, it means that the second and fourth reference signals in the first, third, fifth, and seventh subsets of the reference signal set will be sent.

[0208] Network devices and terminal devices need to reach a pre-agreed agreement on the subset division of the reference signal set. For example, for a reference signal set with 8 reference signals, dividing it into 4 subsets could result in {1,2}, {3,4}, {5,6}, {7,8}, or {1,3}, {5,7}, {2,4}, {6,8}. Therefore, the terminal needs to know the subset division method in advance. The reference signal set can be subsetted in any suitable way; this application does not limit the subset division of the reference signal set.

[0209] Optionally, the subset partitioning of the reference signal set can be pre-configured, for example, through RRC messages, to enable consistency between network devices and terminal devices.

[0210] It is understood that the secondary indicator method is not limited to a secondary bitmap, but can also be a secondary index or any suitable form, and this application does not limit it in this regard.

[0211] It is understandable that hierarchical indication (two levels in this example) partially indicates a subset of reference signals, and partially indicates the corresponding reference signals within that subset. This helps reduce indication overhead, saves signaling resources, and enables flexible configuration of reference signals. In fact, hierarchical indication reduces indication overhead by sacrificing degrees of freedom. For example, with M=64 and K=4, the bit widths of the bitmap, index, and pattern are 64 bits, 24 bits, and 20 bits respectively, allowing for the selection and combination of any four reference signals out of 64. However, with hierarchical indication, if divided into eight groups of eight reference signals each, the bit width is 8+8 = 16 bits, but it cannot achieve arbitrary combinations of reference signals.

[0212] It is understandable that using bit information to indicate the reference signal is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0213] In some embodiments, the second indication includes a sequence corresponding to a reference signal in a set of reference signals.

[0214] The network device can send a second indication to the terminal device in the form of a sequence, indicating a reference signal in the reference signal set. In other words, the second indication sent by the network device to the terminal device can be a sequence that corresponds to a reference signal in the reference signal set, or the sequence can indicate a reference signal in the reference signal set.

[0215] In some embodiments, the sequence may include: a Zadoff-Chu sequence, a Gold sequence, or an m-sequence, etc. Different mapping relationships between shift sequences and reference signals (RS) can be pre-configured, allowing network devices to use sequences with different shifts to indicate the corresponding reference signal. For example:

[0216] When the shift amount is 0, the transmitted sequence can indicate RS0;

[0217] When the shift amount = Δ1, the transmitted sequence can indicate RS1;

[0218] ...

[0219] When the shift amount = Δi, the transmitted sequence can indicate RSi.

[0220] It is understandable that utilizing the good correlation characteristics of Zadoff-Chu sequences, Gold sequences, or m sequences can achieve efficient detection and facilitate the rapid determination of the corresponding reference signal.

[0221] It is understandable that combining it with a sequence can improve compatibility and scalability. For example, the sequence indicating the reference signal can simultaneously have other functions and roles (such as synchronization). By utilizing the correspondence between the sequence and the reference signal, signaling overhead can be reduced, control information can be simplified, and flexible configuration of the reference signal can be achieved.

[0222] In some embodiments, the network device may send a third instruction to the terminal device without sending a second instruction.

[0223] In some scenarios, it is necessary to change the correspondence between the reference signal and the beam, as well as the TCI state corresponding to the reference signal. For example, if the number of available reference signals is limited, and the correspondence between the reference signal and the beam cannot be changed, there may be beams without corresponding reference signals. This is merely an example and not a limitation of this application.

[0224] Network devices can send a third indication to terminal devices, indicating the TCI status of the reference signal, so that the terminal devices can use the appropriate beam to measure the corresponding reference signal and send back a measurement report.

[0225] In some embodiments, the third indication includes second bit information that corresponds to one or more TCI states in the TCI state set.

[0226] Network devices can send a third indication to terminal devices based on bit information, indicating one or more TCI states in the TCI state set. In other words, the third indication sent by the network device to the terminal device may include second bit information, which may correspond to one or more TCI states in the TCI state set, or in other words, the second bit information may indicate one or more TCI states in the TCI state set.

[0227] In some embodiments, the second bit information may be a bitmap, the bit width of which is the same as the total number of TCI states in the TCI state set, and the bit width is N.

[0228] Each TCI state has a TCI-Id. For example, there are 8 TCI-Ids associated with K reference signals, namely [TCI-Id1, ...,TCI-Id8]. When K = 4, 01010101 means that the TCI states of K = 4 reference signals (in ascending order of reference signal index) correspond to the TCI states [TCI-Id2, TCI-Id4, TCI-Id6, TCI-Id8].

[0229] In some embodiments, the second bit information may be the index of the TCI state corresponding to the K beams to be actually transmitted in the TCI state set, where K is a positive integer. That is, the second bit information may include the indexes of the TCI states corresponding to the K beams to be transmitted; therefore, the overall bit width of the second bit information is [missing information].

[0230] In some embodiments, the second bit information may be the code points of K TCI states in the TCI state set.

[0231] Network devices and terminal devices can be pre-configured with a mapping relationship between TCI states and code points through a protocol. The network device can send the code points of the TCI states corresponding to the beams to be transmitted to the terminal device, so as to indicate to the terminal device the beams of these reference signals to be transmitted.

[0232] In some embodiments, the second bit information can be a pattern, which is predefined as a combination indicating K TCI states in a TCI state set, where K is a positive integer and K ≤ N. In other words, the pattern can be a bit-width... The bit information.

[0233] Optionally, the mapping between the pattern diagram and the combination of K TCI states can be pre-configured, for example, through RRC messages, so that the network device and the terminal device can reach an agreement.

[0234] It is understandable that the indication of TCI status can be achieved through different methods such as bitmaps, indices, code points, or pattern patterns. This is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0235] It is understandable that indicating the TCI state through bit information is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0236] In some embodiments, the network device may send a second instruction to the terminal device and a third instruction.

[0237] In some scenarios, network devices can select appropriate reference signals from the set of reference signals and indicate the TCI status of these reference signals to the terminal devices, so that the terminal devices can perform measurements on the reference signals and report measurement reports.

[0238] For example, in dense networks, network devices in adjacent cells each select different reference signals from their respective reference signal sets to indicate TCI state changes to the terminal devices within their cell, and indicate these changes to the terminal devices based on their chosen reference signals. This allows the terminal devices to monitor the reference signals, which helps avoid interference and conflicts between cells. This is merely an example and not a limitation of this application.

[0239] Network devices may send second and third instructions to terminal devices in any suitable manner. The second and / or third instructions may be independent dedicated signaling or may be carried by other signaling or messages. This application does not limit this.

[0240] S402. The terminal device sends a measurement report to the network device, which measures the reference signal based on the second indication and / or the third indication; correspondingly, the network device receives the measurement report from the terminal device, which measures the reference signal based on the second indication and / or the third indication.

[0241] After receiving the second instruction and / or the third instruction, the terminal device can measure the reference signal sent by the network device based on the second instruction and / or the third instruction, and send a measurement report to the network device.

[0242] Correspondingly, after sending the second instruction and / or the third instruction, the network device can send a reference signal to the terminal device. After measuring the reference signal based on the second instruction and / or the third instruction, the terminal device can send a measurement report to the network device, and the network device can receive the measurement report from the terminal device.

[0243] In some embodiments, Figure 4 The DCI shown may include only the second and / or third indications, that is, Figure 4 The communication flow shown can occur after the network device sends additional indication information to the terminal device to trigger aperiodic CSI reporting. That is, Figure 4 The communication process shown may include other steps, and this application does not limit this.

[0244] In some embodiments, the second and / or third indications may be carried in one or more of the following: broadcast message; System Information Block (SIB); Common Control Message; Downlink Control Information (DCI); Infinite Resource Control (RRC) message; Media Access Control Element (MACCE).

[0245] Figure 5 This is a flowchart illustrating a communication processing method provided in an embodiment of this application. Figure 5 The method shown can be executed by a terminal device, or by a chip within the terminal device. Wherein:

[0246] S501. Receive the first DCI from the network device.

[0247] The first DCI includes a first indication, which is used to trigger the reporting of a first aperiodic channel state information (CSI) report, which is associated with a reference signal set.

[0248] The first DCI further includes a second indication and / or a third indication, wherein the second indication is used to indicate one or more reference signals in the reference signal set, and the third indication is used to indicate one or more TCI states in the transmission configuration indication TCI state set associated with the reference signals.

[0249] The reference signal set can be pre-configured by the network device and notified to the terminal device, for example, by pre-configuring and notifying the terminal device via an RRC message. In this application, the total number of reference signals in the reference signal set is denoted as M, where M is a positive integer.

[0250] The TCI state set can be pre-configured by the network device and notified to the terminal device, for example, through an RRC message. In this application, the total number of TCI states in the TCI state set is denoted as N, where N is a positive integer.

[0251] The network device can send a second instruction to the terminal device to instruct the terminal device to monitor one or more reference signals in the reference signal set.

[0252] The network device can also send a third instruction to the terminal device, indicating one or more TCI states associated with the reference signal in the TCI state set, so that the terminal device can determine the corresponding beam of the reference signal based on the spatial information (e.g., QCL type D) in the TCI state.

[0253] In some embodiments, the network device may send a second instruction to the terminal device without sending a third instruction.

[0254] In some scenarios, reference signals and beams can be pre-configured, along with the corresponding TCI status information. This way, the network device only needs to indicate the reference signal to be transmitted to the terminal device, and the terminal device can then obtain the corresponding beam and TCI status. Optionally, this pre-configured information, i.e., the binding / correspondence, can be pre-configured via, for example, RRC messages.

[0255] Based on pre-configured binding / correspondence relationships, network devices can send a second instruction to terminal devices, indicating the reference signal to be sent, so that terminal devices can measure the corresponding reference signal and provide a measurement report.

[0256] In some embodiments, the second indication includes first bit information, which corresponds to one or more reference signals in the reference signal set.

[0257] A network device can send a second indication to a terminal device based on bit information, indicating one or more reference signals in a set of reference signals. In other words, the second indication sent by the network device to the terminal device may include first bit information, which may correspond to one or more reference signals in the set of reference signals, or in other words, the first bit information may indicate one or more reference signals in the set of reference signals.

[0258] In some embodiments, the first bit information may be a bitmap, the bit width of which is the same as the total number of reference signals in the reference signal set, and the bit width is M. It uses 1 or 0 to indicate whether the corresponding reference signal in the reference signal set will be sent or will not be sent.

[0259] For example, if the pre-configured reference signal set contains 8 reference signals and the first bit information is 01010101, it means that reference signals 2, 4, 6, and 8 in the reference signal set will be sent, while reference signals 1, 3, 5, and 7 will not be sent.

[0260] In some embodiments, the first bit information may be the index of K reference signals in the reference signal set, where K is a positive integer and K≤M. That is, the first bit information may include the indices of the K reference signals to be transmitted; therefore, the overall bit width of the first bit information is [value missing].

[0261] For example, if a pre-configured set of reference signals contains eight reference signals, the indices of these eight reference signals can be represented as 000, 001, 010, 011, 100, 101, 110, and 111, respectively. If the network device indicates to the terminal device that reference signals numbered 2, 4, 6, and 8 in the reference signal set will be transmitted, the first bit of information can be 001011101111.

[0262] Alternatively, the index of the reference signal can also be represented using a CSI-RS resource indicator (CRI) or an SSB resource indicator (SS / PBCH Block Resource indicator (SSBRI)).

[0263] In some embodiments, the first bit information may be the code points of K reference signals in the reference signal set.

[0264] Network devices and terminal devices can be pre-configured with a mapping relationship between reference signals and code points through a protocol. The network device can send code points corresponding to the reference signals to be sent to the terminal device to indicate these reference signals to be sent.

[0265] In some embodiments, the first bit information may be a pattern, which is predefined as indicating a combination of K reference signals in a set of reference signals, where K is a positive integer and K ≤ M. In other words, the pattern may be a bit-width... The bit information.

[0266] For example, when M=64 and K=4, In other words, 20 bits can represent all integers from 0 to 635375, meaning a 20-bit pattern can support 635376 possible combinations. For example, when the first bit is 0 (decimal), it can indicate that reference signal {1, 2, 3, 4} will be transmitted; when the first bit is 1 (decimal), it can indicate that reference signal {1, 2, 3, 5} will be transmitted, and so on. The combinations of reference signals represented by the pattern in this application are merely examples and not limitations. This application does not limit the correspondence between the pattern and the combinations of reference signals in the reference signal set.

[0267] Optionally, the mapping relationship between the pattern and the combination of K reference signals can be pre-configured, for example, by an RRC message, so that the network device and the terminal device can reach an agreement.

[0268] It is understandable that indicating the reference signal can be achieved through different methods such as bitmaps, indices, code points, or pattern patterns. This is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0269] In some embodiments, the first bit information includes a first sub-information and a second sub-information, wherein the first sub-information is used to indicate one or more reference signal subsets in the reference signal set, and the second sub-information is used to indicate one or more reference signals in the one or more reference signal subsets.

[0270] Network devices can indicate to terminal devices the reference signals to be transmitted based on a two-level indication method. In the two-level indication method, the reference signal set can be divided into multiple subsets. The first sub-information indicates the subsets in which reference signals will be transmitted, and the second sub-information indicates the reference signals to be transmitted within these subsets.

[0271] For example, the first sub-information in the first bit information can be the first bit map, and the second sub-information can be the second bit map.

[0272] The first bit diagram can be used to indicate which subsets of reference signals in the reference signal set will have reference signals transmitted. For example, if the reference signals in the reference signal set can be divided into 8 subsets, and the first bit diagram is 10101010, it means that reference signals in subsets 1, 3, 5, and 7 will be transmitted.

[0273] The second bitmap can be used to indicate which reference signals in each subset of reference signals will be transmitted. For example, if there are 8 reference signals in a subset of reference signals, and the second bitmap is 01010000, it means that the 2nd and 4th reference signals in each subset will be transmitted.

[0274] If we combine 10101010 in the first bitmap with 01010000 in the second bitmap, it means that the second and fourth reference signals in the first, third, fifth, and seventh subsets of the reference signal set will be sent.

[0275] Network devices and terminal devices need to reach a pre-agreed agreement on the subset division of the reference signal set. For example, for a reference signal set with 8 reference signals, dividing it into 4 subsets could result in {1,2}, {3,4}, {5,6}, {7,8}, or {1,3}, {5,7}, {2,4}, {6,8}. Therefore, the terminal needs to know the subset division method in advance. The reference signal set can be subsetted in any suitable way; this application does not limit the subset division of the reference signal set.

[0276] Optionally, the subset partitioning of the reference signal set can be pre-configured, for example, through RRC messages, to enable consistency between network devices and terminal devices.

[0277] It is understood that the secondary indicator method is not limited to a secondary bitmap, but can also be a secondary index or any suitable form, and this application does not limit it in this regard.

[0278] It is understandable that hierarchical indication (two levels in this example) partially indicates a subset of reference signals, and partially indicates the corresponding reference signals within that subset. This helps reduce indication overhead, saves signaling resources, and enables flexible configuration of reference signals. In fact, hierarchical indication reduces indication overhead by sacrificing degrees of freedom. For example, with M=64 and K=4, the bit widths of the bitmap, index, and pattern are 64 bits, 24 bits, and 20 bits respectively, allowing for the selection and combination of any four reference signals out of 64. However, with hierarchical indication, if divided into eight groups of eight reference signals each, the bit width is 8+8 = 16 bits, but it cannot achieve arbitrary combinations of reference signals.

[0279] It is understandable that using bit information to indicate the reference signal is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0280] In some embodiments, the second indication includes a sequence corresponding to a reference signal in a set of reference signals.

For example:

[0283] When the shift amount is 0, the transmitted sequence can indicate RS0;

[0284] When the shift amount = Δ1, the transmitted sequence can indicate RS1;

[0285] ...

[0286] When the shift amount = Δi, the transmitted sequence can indicate RSi.

[0287] It is understandable that utilizing the good correlation characteristics of Zadoff-Chu sequences, Gold sequences, or m sequences can achieve efficient detection and facilitate the rapid determination of the corresponding reference signal.

[0288] It is understandable that combining it with a sequence can improve compatibility and scalability. For example, the sequence indicating the reference signal can simultaneously have other functions and roles (such as synchronization). By utilizing the correspondence between the sequence and the reference signal, signaling overhead can be reduced, control information can be simplified, and flexible configuration of the reference signal can be achieved.

[0294] In some embodiments, the second bit information may be a bitmap, the bit width of which is the same as the total number of TCI states in the TCI state set, and the bit width is N.

[0295] Each TCI state has a TCI-Id. For example, there are 8 TCI-Ids associated with K reference signals, namely [TCI-Id1, ...,TCI-Id8]. When K = 4, 01010101 means that the TCI states of K = 4 reference signals (in ascending order of reference signal index) correspond to the TCI states [TCI-Id2, TCI-Id4, TCI-Id6, TCI-Id8].

[0296] In some embodiments, the second bit information may be the index of the TCI state corresponding to the K beams to be actually transmitted in the TCI state set, where K is a positive integer. That is, the second bit information may include the indexes of the TCI states corresponding to the K beams to be transmitted; therefore, the overall bit width of the second bit information is [missing information].

[0307] S502. Send a measurement report to the network device, which measures the reference signal based on the second and / or third indications.

[0308] After receiving the second instruction and / or the third instruction, the terminal device can measure the reference signal sent by the network device based on the second instruction and / or the third instruction, and send a measurement report to the network device.

[0309] In some embodiments, Figure 5 The DCI shown may include only the second and / or third indications, that is, Figure 5 The communication flow shown can occur after the network device sends an indication message to the terminal device to trigger additional aperiodic CSI reporting. That is, Figure 5 Other steps may exist before the communication process shown, and this application does not impose any restrictions on this.

[0310] In some embodiments, the second and / or third indications may be carried in one or more of the following: broadcast message; System Information Block (SIB); Common Control Message; Downlink Control Information (DCI); Infinite Resource Control (RRC) message; Media Access Control Element (MACCE).

[0311] It is understood that, based on the method described in this application, the terminal device can obtain the reference signal to be monitored by receiving the second instruction, and / or obtain the TCI state associated with the reference signal by receiving the third instruction. Based on this, the network device can provide flexible instructions to the terminal device regarding the reference signal, so that the terminal device does not need to monitor additional reference signals. Furthermore, since the TCI state contains "Quasi Co-Location (QCL) Type D", i.e., spatial correlation information, the terminal device only needs to monitor the reference signal in the corresponding beam, and does not need to detect all beams, which helps to reduce system overhead and promote system performance improvement.

[0312] Figure 6 This is a flowchart illustrating a communication processing method provided in an embodiment of this application. Figure 6 The method shown can be executed by a network device, or by a chip within the network device. Wherein:

[0313] S601. Send the first DCI to the terminal device.

[0314] The first DCI includes a first indication, which is used to trigger the reporting of a first aperiodic channel state information (CSI) report, which is associated with a reference signal set.

[0315] The first DCI further includes a second indication and / or a third indication, wherein the second indication is used to indicate one or more reference signals in the reference signal set, and the third indication is used to indicate one or more TCI states in the transmission configuration indication TCI state set associated with the reference signals.

[0316] The reference signal set can be pre-configured by the network device and notified to the terminal device, for example, by pre-configuring and notifying the terminal device via an RRC message. In this application, the total number of reference signals in the reference signal set is denoted as M, where M is a positive integer.

[0317] The TCI state set can be pre-configured by the network device and notified to the terminal device, for example, through an RRC message. In this application, the total number of TCI states in the TCI state set is denoted as N, where N is a positive integer.

[0318] The network device can send a second instruction to the terminal device to instruct the terminal device to monitor one or more reference signals in the reference signal set.

[0319] The network device can also send a third instruction to the terminal device, indicating one or more TCI states associated with the reference signal in the TCI state set, so that the terminal device can determine the corresponding beam of the reference signal based on the spatial information (e.g., QCL type D) in the TCI state.

[0320] In some embodiments, the network device may send a second instruction to the terminal device without sending a third instruction.

[0321] In some scenarios, reference signals and beams can be pre-configured, along with the corresponding TCI status information. This way, the network device only needs to indicate the reference signal to be transmitted to the terminal device, and the terminal device can then obtain the corresponding beam and TCI status. Optionally, this pre-configured information, i.e., the binding / correspondence, can be pre-configured via, for example, RRC messages.

[0322] Based on pre-configured binding / correspondence relationships, network devices can send a second instruction to terminal devices, indicating the reference signal to be sent, so that terminal devices can measure the corresponding reference signal and provide a measurement report.

[0323] In some embodiments, the second indication includes first bit information, which corresponds to one or more reference signals in the reference signal set.

[0324] A network device can send a second indication to a terminal device based on bit information, indicating one or more reference signals in a set of reference signals. In other words, the second indication sent by the network device to the terminal device may include first bit information, which may correspond to one or more reference signals in the set of reference signals, or in other words, the first bit information may indicate one or more reference signals in the set of reference signals.

[0325] In some embodiments, the first bit information may be a bitmap, the bit width of which is the same as the total number of reference signals in the reference signal set, and the bit width is M. It uses 1 or 0 to indicate whether the corresponding reference signal in the reference signal set will be sent or will not be sent.

[0326] For example, if the pre-configured reference signal set contains 8 reference signals and the first bit information is 01010101, it means that reference signals 2, 4, 6, and 8 in the reference signal set will be sent, while reference signals 1, 3, 5, and 7 will not be sent.

[0327] In some embodiments, the first bit information may be the index of K reference signals in the reference signal set, where K is a positive integer and K≤M. That is, the first bit information may include the indices of the K reference signals to be transmitted; therefore, the overall bit width of the first bit information is [value missing].

[0328] For example, if a pre-configured set of reference signals contains eight reference signals, the indices of these eight reference signals can be represented as 000, 001, 010, 011, 100, 101, 110, and 111, respectively. If the network device indicates to the terminal device that reference signals numbered 2, 4, 6, and 8 in the reference signal set will be transmitted, the first bit of information can be 001011101111.

[0329] Alternatively, the index of the reference signal can also be represented using a CSI-RS resource indicator (CRI) or an SSB resource indicator (SS / PBCH Block Resource indicator (SSBRI)).

[0330] In some embodiments, the first bit information may be the code points of K reference signals in the reference signal set.

[0331] Network devices and terminal devices can be pre-configured with a mapping relationship between reference signals and code points through a protocol. The network device can send code points corresponding to the reference signals to be sent to the terminal device to indicate these reference signals to be sent.

[0332] In some embodiments, the first bit information may be a pattern, which is predefined as indicating a combination of K reference signals in a set of reference signals, where K is a positive integer and K ≤ M. In other words, the pattern may be a bit-width... The bit information.

[0333] For example, when M=64 and K=4, In other words, 20 bits can represent all integers from 0 to 635375, meaning a 20-bit pattern can support 635376 possible combinations. For example, when the first bit is 0 (decimal), it can indicate that reference signal {1, 2, 3, 4} will be transmitted; when the first bit is 1 (decimal), it can indicate that reference signal {1, 2, 3, 5} will be transmitted, and so on. The combinations of reference signals represented by the pattern in this application are merely examples and not limitations. This application does not limit the correspondence between the pattern and the combinations of reference signals in the reference signal set.

[0334] Optionally, the mapping relationship between the pattern and the combination of K reference signals can be pre-configured, for example, by an RRC message, so that the network device and the terminal device can reach an agreement.

[0335] It is understandable that indicating the reference signal can be achieved through different methods such as bitmaps, indices, code points, or pattern patterns. This is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0336] In some embodiments, the first bit information includes a first sub-information and a second sub-information, wherein the first sub-information is used to indicate one or more reference signal subsets in the reference signal set, and the second sub-information is used to indicate one or more reference signals in the one or more reference signal subsets.

[0337] Network devices can indicate to terminal devices the reference signals to be transmitted based on a two-level indication method. In the two-level indication method, the reference signal set can be divided into multiple subsets. The first sub-information indicates the subsets in which reference signals will be transmitted, and the second sub-information indicates the reference signals to be transmitted within these subsets.

[0338] For example, the first sub-information in the first bit information can be the first bit map, and the second sub-information can be the second bit map.

[0339] The first bit diagram can be used to indicate which subsets of reference signals in the reference signal set will have reference signals transmitted. For example, if the reference signals in the reference signal set can be divided into 8 subsets, and the first bit diagram is 10101010, it means that reference signals in subsets 1, 3, 5, and 7 will be transmitted.

[0340] The second bitmap can be used to indicate which reference signals in each subset of reference signals will be transmitted. For example, if there are 8 reference signals in a subset of reference signals, and the second bitmap is 01010000, it means that the 2nd and 4th reference signals in each subset will be transmitted.

[0341] If we combine 10101010 in the first bitmap with 01010000 in the second bitmap, it means that the second and fourth reference signals in the first, third, fifth, and seventh subsets of the reference signal set will be sent.

[0342] Network devices and terminal devices need to reach a pre-agreed agreement on the subset division of the reference signal set. For example, for a reference signal set with 8 reference signals, dividing it into 4 subsets could result in {1,2}, {3,4}, {5,6}, {7,8}, or {1,3}, {5,7}, {2,4}, {6,8}. Therefore, the terminal needs to know the subset division method in advance. The reference signal set can be subsetted in any suitable way; this application does not limit the subset division of the reference signal set.

[0343] Optionally, the subset partitioning of the reference signal set can be pre-configured, for example, through RRC messages, to enable consistency between network devices and terminal devices.

[0344] It is understood that the secondary indicator method is not limited to a secondary bitmap, but can also be a secondary index or any suitable form, and this application does not limit it in this regard.

[0345] It is understandable that hierarchical indication (two levels in this example) partially indicates a subset of reference signals, and partially indicates the corresponding reference signals within that subset. This helps reduce indication overhead, saves signaling resources, and enables flexible configuration of reference signals. In fact, hierarchical indication reduces indication overhead by sacrificing degrees of freedom. For example, with M=64 and K=4, the bit widths of the bitmap, index, and pattern are 64 bits, 24 bits, and 20 bits respectively, allowing for the selection and combination of any four reference signals out of 64. However, with hierarchical indication, if divided into eight groups of eight reference signals each, the bit width is 8+8 = 16 bits, but it cannot achieve arbitrary combinations of reference signals.

[0346] It is understandable that using bit information to indicate the reference signal is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0347] In some embodiments, the second indication includes a sequence corresponding to a reference signal in a set of reference signals.

[0348] The network device can send a second indication to the terminal device in the form of a sequence, indicating a reference signal in the reference signal set. In other words, the second indication sent by the network device to the terminal device can be a sequence that corresponds to a reference signal in the reference signal set, or the sequence can indicate a reference signal in the reference signal set.

[0349] In some embodiments, the sequence may include: a Zadoff-Chu sequence, a Gold sequence, or an m-sequence, etc. Different mapping relationships between shift sequences and reference signals (RS) can be pre-configured, allowing network devices to use sequences with different shifts to indicate the corresponding reference signal. For example:

[0350] When the shift amount is 0, the transmitted sequence can indicate RS0;

[0351] When the shift amount = Δ1, the transmitted sequence can indicate RS1;

[0352] ...

[0353] When the shift amount = Δi, the transmitted sequence can indicate RSi.

[0354] It is understandable that utilizing the good correlation characteristics of Zadoff-Chu sequences, Gold sequences, or m sequences can achieve efficient detection and facilitate the rapid determination of the corresponding reference signal.

[0355] It is understandable that combining it with a sequence can improve compatibility and scalability. For example, the sequence indicating the reference signal can simultaneously have other functions and roles (such as synchronization). By utilizing the correspondence between the sequence and the reference signal, signaling overhead can be reduced, control information can be simplified, and flexible configuration of the reference signal can be achieved.

[0356] In some embodiments, the network device may send a third instruction to the terminal device without sending a second instruction.

[0357] In some scenarios, it is necessary to change the correspondence between the reference signal and the beam, as well as the TCI state corresponding to the reference signal. For example, if the number of available reference signals is limited, and the correspondence between the reference signal and the beam cannot be changed, there may be beams without corresponding reference signals. This is merely an example and not a limitation of this application.

[0358] Network devices can send a third indication to terminal devices, indicating the TCI status of the reference signal, so that the terminal devices can use the appropriate beam to measure the corresponding reference signal and send back a measurement report.

[0359] In some embodiments, the third indication includes second bit information that corresponds to one or more TCI states in the TCI state set.

[0360] Network devices can send a third indication to terminal devices based on bit information, indicating one or more TCI states in the TCI state set. In other words, the third indication sent by the network device to the terminal device may include second bit information, which may correspond to one or more TCI states in the TCI state set, or in other words, the second bit information may indicate one or more TCI states in the TCI state set.

[0361] In some embodiments, the second bit information may be a bitmap, the bit width of which is the same as the total number of TCI states in the TCI state set, and the bit width is N.

[0362] Each TCI state has a TCI-Id. For example, there are 8 TCI-Ids associated with K reference signals, namely [TCI-Id1, ...,TCI-Id8]. When K = 4, 01010101 means that the TCI states of K = 4 reference signals (in ascending order of reference signal index) correspond to the TCI states [TCI-Id2, TCI-Id4, TCI-Id6, TCI-Id8].

[0363] In some embodiments, the second bit information may be the index of the TCI state corresponding to the K beams to be actually transmitted in the TCI state set, where K is a positive integer. That is, the second bit information may include the indexes of the TCI states corresponding to the K beams to be transmitted; therefore, the overall bit width of the second bit information is [missing information].

[0364] In some embodiments, the second bit information may be the code points of K TCI states in the TCI state set.

[0365] Network devices and terminal devices can be pre-configured with a mapping relationship between TCI states and code points through a protocol. The network device can send the code points of the TCI states corresponding to the beams to be transmitted to the terminal device, so as to indicate to the terminal device the beams of these reference signals to be transmitted.

[0366] In some embodiments, the second bit information can be a pattern, which is predefined as a combination indicating K TCI states in a TCI state set, where K is a positive integer and K ≤ N. In other words, the pattern can be a bit-width... The bit information.

[0367] Optionally, the mapping between the pattern diagram and the combination of K TCI states can be pre-configured, for example, through RRC messages, so that the network device and the terminal device can reach an agreement.

[0368] It is understandable that the indication of TCI status can be achieved through different methods such as bitmaps, indices, code points, or pattern patterns. This is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0369] It is understandable that indicating the TCI state through bit information is simple and easy to implement, and allows for flexible configuration of the reference signal.

[0370] In some embodiments, the network device may send a second instruction to the terminal device and a third instruction.

[0371] In some scenarios, network devices can select appropriate reference signals from the set of reference signals and indicate the TCI status of these reference signals to the terminal devices, so that the terminal devices can perform measurements on the reference signals and report measurement reports.

[0372] For example, in dense networks, network devices in adjacent cells each select different reference signals from their respective reference signal sets to indicate TCI state changes to the terminal devices within their cell, and indicate these changes to the terminal devices based on their chosen reference signals. This allows the terminal devices to monitor the reference signals, which helps avoid interference and conflicts between cells. This is merely an example and not a limitation of this application.

[0373] Network devices may send second and third instructions to terminal devices in any suitable manner. The second and / or third instructions may be independent dedicated signaling or may be carried by other signaling or messages. This application does not limit this.

[0374] S602. Receive a measurement report from the terminal device that measures the reference signal based on the second instruction and / or the third instruction.

[0375] After sending the second instruction and / or the third instruction, the network device may send a reference signal to the terminal device. After measuring the reference signal based on the second instruction and / or the third instruction, the terminal device may send a measurement report to the network device, and the network device may receive the measurement report from the terminal device.

[0376] In some embodiments, Figure 6 The DCI shown may include only the second and / or third indications, that is, Figure 6 The communication process shown can occur after the network device sends an indication message to the terminal device to trigger aperiodic CSI reporting. That is to say, Figure 6 Other steps may exist before the communication process shown, and this application does not impose any restrictions on this.

[0377] In some embodiments, the second and / or third indications may be carried in one or more of the following: broadcast message; System Information Block (SIB); Common Control Message; Downlink Control Information (DCI); Infinite Resource Control (RRC) message; Media Access Control Element (MACCE).

[0378] It is understood that, based on the method described in this application, the network device can send a second instruction to the terminal device to enable the terminal device to know the reference signal that needs to be monitored, and / or send a third instruction to the terminal device to enable the terminal device to know the TCI state associated with the reference signal. Based on this, the network device can flexibly instruct the terminal device on the reference signal, so that the terminal device does not need to monitor additional reference signals. Furthermore, since the TCI state contains "Quasi Co-Location (QCL) Type D", i.e., spatial correlation information, the terminal device only needs to monitor the reference signal in the corresponding beam, and does not need to detect all beams, which helps to reduce system overhead and promote system performance improvement.
