Beam report reporting method and related device

Abstract

The embodiment of the invention provides a beam report reporting method and a related device. The reporting method comprises the following steps: sending a first message comprising a beam report, first information and second information; and if the timing duration after the first message is sent is greater than or equal to the first duration or greater than or equal to the second duration, releasing the QCL. The first information in the first message is used for indicating the QCL of the reference signal in the beam report stored by the terminal, and the network equipment can determine the beam to which the QCL stored by the terminal belongs based on the first information so as to carry out adaptive scheduling, so that the adaptive beam scheduling capability is enhanced. The second information in the first message can indicate the effective duration of the QCL, and the network device further determines the effective storage duration of the QCL, thereby facilitating flexible scheduling. The terminal releases the QCL, so that invalid occupation of memory resources caused by the fact that the QCL does not work and is not released can be avoided.

Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a beam reporting method and related devices. Background Art

[0002] In the beam management process, the terminal can report beam reports based on UE-initiated / event-driven triggering, reducing uplink reporting overhead and control signaling overhead.

[0003] In one application scenario, a terminal triggers a beam report based on Event-7. Event-7 is defined as the quality of at least one new beam reaching a threshold. The terminal initiates a beam report based on Event-7. Furthermore, after initiating a beam report, the terminal can also store the quasi-co-location (QCL) of the reference signal in the reported beam.

[0004] However, the beam report reported by the terminal based on Event-7 includes information about multiple candidate beams. The quality of these candidate beams may not all meet the threshold. The terminal can store the reference signal QCL of beams whose quality meets the threshold. Therefore, the network device cannot clearly identify the beam to which the terminal's stored QCL belongs based on the beam report reported by the terminal, making adaptive scheduling impossible. Summary of the Invention

[0005] The present application provides a beam reporting method and related devices, the purpose of which is to enhance the adaptive scheduling beam of network equipment.

[0006] In order to achieve the above objectives, this application provides the following technical solutions:

[0007] In a first aspect, this application provides a method for reporting beam reports. This method can be performed, for example, by a terminal, or by components configured in the terminal (such as circuits, chips, or chip systems), or by a logic module or software that implements all or part of the terminal's functions. This application is not limited to this. The following description uses a terminal as an example.

[0008] The reporting method of the beam report includes: sending a first message, the first message including a beam report, first information and second information, the first information is used to indicate the QCL of the reference signal in the beam report stored by the terminal, and the second information is used to indicate the valid duration of the QCL indicated by the first information; when the timing duration after the first message is sent is greater than or equal to the first duration, releasing the QCL of the reference signal in the stored beam report, the first duration is the valid duration of the QCL indicated by the second information, or when the timing duration after the first message is sent is greater than or equal to the second duration, releasing the QCL of the reference signal in the stored beam report, the second duration is the sum of the valid duration of the QCL indicated by the second information and the extended storage duration of the QCL indicated by the first information.

[0009] In the above technical solution, the first information in the first message sent by the terminal is used to indicate the QCL of the reference signal in the beam report stored by the terminal. The network device can clarify the beam to which the QCL stored by the terminal belongs based on the first information in the first message, that is, clarify which beam's reference signal QCL the terminal stores, and can perform adaptive scheduling based on the QCL stored by the terminal, thereby enhancing the network device's ability to adaptively schedule beams. Furthermore, the QCL stored by the terminal can be scheduled in a timely manner by the network device, which can avoid the problem of the QCL stored by the terminal becoming invalid due to not being used in time, thereby causing the memory resources to be invalidly occupied. Furthermore, the second information in the first message can indicate the effective duration of the QCL. The network device can further clarify the effective storage duration of the QCL stored by the terminal based on the second information, thereby facilitating flexible scheduling.

[0010] Optionally, during the period when the timing duration after the first message is sent does not reach (i.e., is less than) the first duration, the terminal does not receive the scheduling of the network device, that is, during the first duration after the terminal sends the first message, the terminal does not receive the scheduling of the network device. When the timing duration after the first message is sent is greater than or equal to the first duration, the terminal releases the QCL of the reference signal stored in the beam report. In this way, the terminal can avoid the invalid occupation of the terminal's memory resources due to the fact that the QCL stored in the terminal is ineffective and not released by releasing the stored QCL of the reference signal.

[0011] Optionally, during the period when the timing duration after the first message is sent does not reach (i.e., is less than) the second duration, the terminal does not receive the scheduling of the network device, and optionally does not receive the indication message of delayed storage of QCL. In this way, the terminal can also release the stored QCL of the reference signal to avoid the terminal's memory resources being invalidly occupied due to the QCL stored in the terminal being ineffective and not released.

[0012] In one possible implementation, the first information includes first indication information or the QCL of the reference signal in the beam report stored by the terminal, and the first indication information is used to indicate the QCL of the reference signal in the beam report stored by the terminal.

[0013] In one possible implementation, the second information includes second indication information or the valid duration of the QCL indicated by the first information, and the second indication information is used to indicate the valid duration of the QCL indicated by the first information.

[0014] In one possible implementation, the valid duration of the QCL indicated by the second information is determined according to a parameter table or configured by the network device, where the parameter table includes multiple valid durations of the QCL.

[0015] In one possible implementation, the method for reporting the beam report further includes: receiving a second message, the second message including third information, the third information being used to indicate an extended storage duration of the QCL indicated by the first information. Optionally, after receiving the second message, if the timing duration after the first message is sent is greater than or equal to the first duration, the QCL of the reference signal in the stored beam report is not released, and if the timing duration after the first message is sent is greater than or equal to the second duration, the QCL of the reference signal in the stored beam report is released.

[0016] In one possible implementation, the third information includes third indication information or the extended storage time of the QCL indicated by the first information, and the third indication information is used to indicate the extended storage time of the QCL indicated by the first information.

[0055] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context. It should also be understood that in the embodiments of the present application, "one or more" refers to one, two or more; "and / or" describes the association relationship of associated objects, indicating that three relationships may exist; for example, A and / or B can represent: the existence of A alone, the existence of A and B at the same time, and the existence of B alone, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship.

[0056] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0057] The "multiple" involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first" and "second" are only used for the purpose of distinguishing the description and cannot be understood as indicating or implying relative importance or order.

[0058] The technical solutions provided in the embodiments of the present application can be applied to communication systems, which may include but are not limited to the following systems, such as: second-generation (2G) communication systems, third-generation (3G) communication systems, long-term evolution (LTE) systems, universal mobile telecommunication systems (UMTS), worldwide interoperability for microwave access (WiMAX) communication systems, fifth-generation (5G) systems or new radio (NR), 5.5G systems or sixth-generation (6G) systems and future mobile communication systems, vehicle to other devices (V2X); V2X may include vehicle to network (V2N), vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to pedestrian (V2P), etc., long-term evolution-vehicle (LTE-V), Internet of Vehicles, machine type communication (MTC), and Internet of Things (IoT). things (IOT), ambient internet of things (AIOT), long term evolution-machine (LTE-M), machine to machine (M2M), etc.

[0059] The communication system is applicable to scenarios including terrestrial cellular communication, non-terrestrial network (NTN), satellite communication, high altitude platform station (HAPS) communication, vehicle-to-everything (V2X) communication, integrated access and backhaul (IAB) communication, and reconfigurable intelligent surface (RIS) communication.

[0060] For example, Figure 1 A schematic diagram of the architecture of a communication system provided in an embodiment of the present application is shown.

[0061] like Figure 1 As shown, the communication system includes a first device 100 and a second device 200 .

[0062] The first device 100 can be a device on the network side for providing network communication functions, and in some cases is also called a network device or a network element. The network device can generally be a base station (including functional units of a base station, or a combination of functional units of a base station) or a core network unit, wherein the core network unit can be a functional unit in the core network, including but not limited to an access and mobility management function (AMF) unit or a session management function (SMF) unit.

[0063] In the embodiment of the present application, the base station can be any device with wireless transceiver functions, including but not limited to: an evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in long term evolution (LTE), a base station (gNodeB or gNB) or a transmission receiving point (TRP) in new radio (NR), a base station of subsequent evolution of 3GPP, an access node in a Wi-Fi system, a wireless relay node, a wireless backhaul node, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The base station can include one or more co-site or non-co-site transmission points (TRP). The base station can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The base station can communicate with the terminal 200, or communicate with the terminal 200 through a relay station. The terminal can communicate with multiple base stations of different technologies. For example, the terminal can communicate with a base station supporting the LTE network, and can also communicate with a base station supporting the 5G network. It can also establish dual connections with a base station supporting the LTE network and a base station supporting the 5G network.

[0064] In practical applications, when network equipment functions as access network equipment, multiple network devices can collaborate to assist terminals in achieving wireless access, with different network devices each implementing portions of a base station's functionality. For example, a network device can be a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU can be separate or included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or radio unit, such as a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).

[0065] In different systems, the CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meanings. For example, in the ORAN system, the CU may also be called an O-CU (Open CU), the DU may also be called an O-DU, the CU-CP may also be called an O-CU-CP, the CU-UP may also be called an O-CU-UP, and the RU may also be called an O-RU. Any of the CU (or CU-CP, CU-UP), DU, and RU in this application may be implemented as a software module, a hardware module, or a combination of software and hardware modules. The CU (or CU-CP and CU-UP), DU, and RU can implement different protocol layer functions.

[0066] Figure 2 This is a schematic diagram of the structure of an access network device. As an implementation example, Figure 2As shown, the access network device may include at least one CU and at least one DU. This design can be referred to as CU-DU separation. A CU can be connected to one or more DUs. The CU and DU can be divided based on the protocol layers of the wireless network: for example, the functions of the PDCP layer and above (such as the RRC layer and SDAP layer) are located in the CU, while the functions of the protocol layers below the PDCP layer (such as the RLC layer, media access control (MAC) layer, and PHY layer) are located in the DU. Another example is that the functions of the protocol layers above the PDCP layer are located in the CU, while the functions of the protocol layers below the PDCP layer are located in the DU, without limitation. When a CU includes a CU-CP and a CU-UP, the CU-CP implements the control plane functions of the CU, and the CU-UP implements the user plane functions of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, the CU-CP implements the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP implements the SDAP layer functions and the user plane functions of the PDCP layer. This application does not limit the names of the CU and DU. The above division of the processing functions of CU and DU according to the protocol layer is only an example, and they can also be divided in other ways.

[0067] The CU can be connected to the core network. Optionally, the CU can have some of the functions of the core network.

[0068] Furthermore, some functions of DU can be separated. Figure 2As shown, these functions can be implemented by a radio unit (RU). The RU can have radio frequency functions. This application does not limit the name of the RU. The DU and RU can be split or separated at the PHY layer. For example, the DU can implement high-level functions in the PHY layer, and the RU can implement low-level functions in the PHY layer, or implement these low-level functions and radio frequency functions. High-level functions in the PHY layer include functions closer to the MAC layer, and low-level functions in the PHY layer include functions closer to the radio frequency. For example, high-level functions in the PHY layer include one or more of the following: forward error correction (FEC) encoding / decoding, scrambling, or modulation / demodulation. Low-level functions in the PHY layer include one or more of the following: fast Fourier transform (FFT) / inverse fast Fourier transform (IFFT), beamforming, or physical random access channel (PRACH) extraction and filtering. The RU can communicate radio frequency signals with terminal devices over the air interface. The PHY layer code precoding function can be located in the DU or the RU. The DU and RU can be split in various ways, without limitation. An interface exists between the DU and RU. For example, depending on the split method, the interface between the DU and RU can be a common public radio interface (CPRI) or an enhanced common public radio interface (eCPRI).

[0069] Optionally, any one of the above-mentioned CU, CU-CP, CU-UP, DU and RU can be a software module, a hardware structure, or a software module plus a hardware structure, without limitation. The existence forms of different entities can be the same or different. For example, CU, CU-CP, CU-UP and DU are software modules, and RU is a hardware structure. For the sake of brevity, all possible combinations are not listed here one by one. These modules and their execution methods are also within the scope of protection of the embodiments of the present application. For example, when the method of the embodiment of the present application is executed by an access network device, it can be specifically executed by at least one of CU, CU-CP, CU-UP, DU, or RU.

[0070] The second device 200 may be a device accessing a network, typically a terminal.

[0071] In the embodiments of the present application, the terminal can be in various forms, for example, a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a vehicle-mounted terminal device, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, a wearable terminal device, etc. The terminal can also be sometimes referred to as a terminal device, user equipment (UE), access terminal device, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal device, mobile device, UE terminal device, wireless communication device, UE agent or UE device, etc. The terminal can also be a fixed terminal or a mobile terminal.

[0072] In some embodiments, the communication system may further include other devices that communicate with the first device and / or the second device, which is not limited in this application.

[0073] To facilitate understanding, the concepts involved in this application are first explained below.

[0074] 1. The physical downlink shared channel (PDSCH) is used to transmit downlink data.

[0075] 2. The physical downlink control channel (PDCCH) is used to transmit downlink control information.

[0076] 3. Beamforming

[0077] Network devices can interact with terminals using beamforming technology. Network devices typically form multiple downlink (DL) transmission beams. One or more DL transmission beams can send downlink signals to terminals within the beam's coverage area, and terminals within the beam's coverage area can receive downlink signals through the beams.

[0078] 4. Synchronization signal block (SS / PBCH block, SSB), SSB opportunity, time slot

[0079] In NR systems, an SSB consists of a primary synchronous signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH), which are used for initial cell access, time-frequency synchronization, and measurement. SSBs are transmitted using multiple beams, and the terminal selects the optimal beam for access by measuring the SSB signal strength of different beams.

[0080] Transmitting an SSB will occupy a certain time domain symbol, so the resource for transmitting an SSB is called a candidate SSB opportunity, or SSB opportunity for short.

[0081] A slot can include multiple groups of time domain symbols, and each group of time domain symbols can include multiple time domain symbols. A slot can support up to two SSBs, which are located on different groups of time domain symbols in the slot. In other words, a slot includes a maximum of 2 SSB opportunities.

[0082] 5. Quasi-co-location (QCL)

[0083] QCL describes the similarity of signals at two antenna ports in the spatial or time-frequency domain. It is categorized into Type A (overall similarity), Type B (Doppler correlation), Type C (delay correlation), and Type D (spatial parameter similarity). Type D QCL is commonly used in beam management to indicate beam direction consistency.

[0084] 6. Transmission configuration indicator state (TCI state)

[0085] The TCI state is the core mechanism for configuring the Quasi Co-location Relationship (QCL) between downlink reference signals and data channels. The TCI state is a set of network-configured parameters that describe the QCL relationship between downlink reference signals (such as SSBs and the Channel State Information Reference Signal (CSI-RS)) and data channels (such as the DMRS of the PDSCH / PDCCH).

[0086] Each TCI state can contain one or two downlink reference signals (such as SSB or CSI-RS) and specify a QCL type (Type A / B / C / D) for each reference signal, indicating the channel parameters that the data channel can obtain from the reference signal.

[0087] Example: If the PDSCH DMRS is configured as QCL-Type D with SSB, the PDSCH beam direction is consistent with the SSB beam.

[0088] Among them, the relevant introductions to PDSCH, PDCCH, beamforming, SSB, SSB opportunity, time slot, QCL and TCI status are only for the purpose of facilitating the understanding of the technical solution of the present application and do not constitute any limitation to the present application.

[0089] In the beam management process, network equipment can configure or activate frequent periodic beam reports or semi-persistent beam reports, or trigger frequent non-periodic beam reports, so as to obtain the preferred beam for data or control transmission in a timely manner. However, this also causes a large uplink reporting overhead and control signaling overhead. To this end, the terminal can report beam reports based on UE-initiated / event-driven (UEI / ED) triggering, that is, the terminal performs active triggering or beam measurement and reporting based on specific event triggering, which can reduce uplink reporting overhead and control signaling overhead.

[0090] Exemplarily, the beam report triggered by Event-7 is UEI / ED-triggered beam management. The judgment feature of Event-7 is that the quality of at least one new beam reaches a threshold, and the terminal can initiate a beam report based on Event-7. In addition, after the terminal initiates the beam report, it can also store the QCL of the reference signal in the reported beam to reduce the beam application delay. In the following, the new beam whose quality reaches the threshold is referred to as the beam with the best quality, the optimal candidate beam, etc., but this does not constitute a limitation.

[0091] However, after the terminal initiates a beam report based on Event-7 and stores the QCL of the reference signal in the reported beam, if the network device decides not to update it, the QCL stored by the terminal will become ineffective and not released, resulting in invalid occupation of the terminal's memory resources.

[0092] In addition, the beam report reported by the terminal based on Event-7 includes information about multiple candidate beams. The quality of multiple candidate beams may not all reach the threshold. The terminal can store the QCL of the reference signal of the beam whose quality reaches the threshold. Therefore, the network device cannot clearly identify the beam to which the QCL stored by the terminal belongs based on the beam report reported by the terminal, that is, it cannot clearly identify which beam's reference signal QCL the terminal has stored, and thus cannot perform adaptive scheduling. Furthermore, the network device cannot perform adaptive scheduling, and the QCL stored by the terminal may become invalid due to not being used in a timely manner. The invalid QCL also occupies the terminal's memory resources, resulting in invalid occupation of memory resources.

[0093] To this end, an embodiment of the present application provides a method for reporting beam reports, which can enhance the adaptive scheduling beams of network devices.

[0094] Figure 3 The flowchart of the beam report reporting method provided in an embodiment of the present application is exemplified.

[0095] like Figure 3 As shown, the beam report reporting method provided in the embodiment of the present application includes:

[0096] S301. A terminal sends a first message to a network device. Correspondingly, the network device receives the first message.

[0097] The first message includes a beam report and first information, and the first information is used to indicate the QCL of the reference signal in the beam report stored by the terminal.

[0098] In some embodiments, the first message is uplink control information (UCI), that is, the terminal sends UCI to the network device, and the UCI may include report content of the beam report and the first information.

[0099] In some other embodiments, the first message is a media access control element (MAC control element, MAC CE), that is, the terminal sends a MAC CE to the network device, and the MAC CE may include the report content of the beam report and the first information.

[0100] Exemplarily, the report content of the beam report includes information of multiple candidate beams, where the multiple candidate beams include the beam with the best quality (ie, the optimal candidate beam) and other candidate beams.

[0101] Optionally, the information of the optimal candidate beam may include: an identifier of the candidate beam, a beam measurement quality of the candidate beam, etc., wherein the identifier of the candidate beam, such as the synchronization signal block resource indicator (SSBRI) of the candidate beam, and / or the CSI reference signal resource indicator (CSI-RS resource indicator, CRI); the beam measurement quality of the candidate beam, such as the physical layer reference signal received power (Layer 1 signal to interference plus noise ratio, Layer 1 RSRP or L1-RSRP) of the candidate beam, and / or the physical layer signal to interference plus noise ratio (Layer 1 signal to interference plus noise ratio, Layer 1 SINR or L1-SINR) of the candidate beam.

[0102] Optionally, the information of other candidate beams may include the identification of the candidate beam (such as SSBRI and / or CRI, etc.), and the beam measurement quality of the candidate beam (such as L1-RSRP and / or L1-SINR, etc.); more optionally, the information of other candidate beams may also include the identification of the candidate beam, and the difference in beam measurement quality between the other candidate beams and the optimal candidate beam, for example: the difference between the L1-RSRP of the other candidate beams and the L1-RSRP of the optimal candidate beam.

[0103] The reference signal in the beam report can be a CSI-RS or SSB. The SSB can be associated with one or more CSI-RSs, and the CSI-RS can be associated with a unique SSB. The reference signal in the beam report is an SSB, and the first information is used to indicate the QCL of the SSB in the beam report stored by the terminal. The reference signal in the beam report is a CSI-RS, and the first information is used to indicate the QCL of the CSI-RS in the beam report stored by the terminal, or used to indicate the QCL of the SSB associated with the CSI-RS in the beam report stored by the terminal.

[0104] Exemplarily, the QCL of the reference signal in the beam report stored by the terminal is the QCL of the reference signal (such as CSI-RS or SSB) corresponding to the optimal candidate beam. Therefore, the first information is used to indicate the QCL of the reference signal corresponding to the optimal candidate beam.

[0105] Optionally, an implementation method for the first information to indicate the QCL of the reference signal in the beam report stored by the terminal includes: the first information includes the QCL of the reference signal in the beam report stored by the terminal, that is, the first information includes the QCL of the reference signal corresponding to the optimal candidate beam.

[0106] Optionally, another implementation method of using the first information to indicate the QCL of the reference signal in the stored beam report includes: the first information includes first indication information, and the first indication information is used to indicate the QCL of the reference signal in the beam report stored by the terminal, that is, used to indicate the QCL of the reference signal corresponding to the optimal candidate beam.

[0107] In one implementation, the first indication information occupies one or more bits, and the value of the one or more bits is used to indicate the QCL of the reference signal corresponding to the optimal candidate beam.

[0108] In some embodiments, the first field in the first message may be used to carry a beam report, and the second field may be used to carry the first information. Exemplarily, the second field may be located before or after the first field; further exemplarily, the second field may be located between the information carried by the first field. Optionally, the beam report includes the identification of the candidate beam and the beam measurement quality of the candidate beam. That is, the first field carries the identification of the candidate beam and the beam measurement quality of the candidate beam, and the second field may be located between the identification of the candidate beam and the beam measurement quality of the candidate beam.

[0109] In other embodiments, after the terminal generates a beam report and stores the QCL of the reference signal corresponding to the optimal candidate beam, it may send a first message to the network device.

[0110] In an embodiment of the present application, the first information in the first message sent by the terminal is used to indicate the QCL of the reference signal in the beam report stored by the terminal. The network device can clarify the beam to which the QCL stored by the terminal belongs based on the first information in the first message, that is, clarify which beam's reference signal QCL the terminal has stored. Adaptive scheduling can be performed based on the QCL stored by the terminal, thereby enhancing the network device's ability to adaptively schedule beams. Furthermore, the QCL stored by the terminal can be scheduled in a timely manner by the network device, which can prevent the QCL stored by the terminal from becoming invalid due to not being used in a timely manner, thereby causing memory resources to be ineffectively occupied.

[0111] In some other embodiments, the first message may further include second information, where the second information is used to indicate the valid duration (or storage valid duration) of the QCL indicated by the first information. Based on this, the first message includes the beam report, the first information, and the second information.

[0112] Optionally, when the timing duration after the first message is sent is greater than or equal to the first duration, the terminal may release the QCL of the reference signal in the stored beam report. The first duration is the effective duration of the QCL indicated by the second information, and the QCL is indicated by the first information. The second duration is also the effective duration of the QCL indicated by the first information and indicated by the second information.

[0113] Alternatively, when the timing duration after the first message is sent is greater than or equal to the second duration, the terminal may release the QCL of the reference signal in the stored beam report, where the second duration is the sum of the effective duration of the QCL indicated by the second information and the extended storage duration of the QCL indicated by the first information.

[0114] The valid duration of the QCL refers to the limited duration for the terminal to store the QCL indicated by the first information. If the duration for which the terminal stores the QCL indicated by the first information is greater than or equal to the valid duration, the QCL indicated by the first information may be released.

[0115] In one example, the effective duration of the QCL indicated by the second information is 100ms. If the terminal stores the QCL indicated by the first information for a duration greater than 100ms, the QCL indicated by the first information may be released.

[0116] Here, releasing the QCL indicated by the first message can be understood as deleting the QCL indicated by the first message.

[0117] In one implementation, the terminal does not receive the scheduling of the network device within a first time period after sending the first message (that is, the period when the timing time after the terminal sends the first message is less than the first time period), and when the timing time after the first message is sent is greater than or equal to the first time period, the terminal may release the QCL of the reference signal in the stored beam report.

[0118] In another implementation, the terminal receives scheduling from the network device within a first time period after sending the first message, and can use the stored QCL to receive the downlink reference signal corresponding to the candidate beam.

[0119] When the duration of QCL storage in the terminal is greater than or equal to the effective duration, the terminal releases the stored QCL, which can avoid the terminal's memory resources being invalidly occupied due to the QCL stored in the terminal being ineffective and not released.

[0120] Optionally, the implementation method of the effective duration of the QCL indicated by the first information indicated by the second information may be: the second information includes the effective duration of the QCL indicated by the first information. For example, the second information includes the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam.

[0121] Optionally, the implementation method of the second information indicating the effective duration of the QCL indicated by the first information may also be: the second information includes second indication information, and the second indication information is used to indicate the effective duration of the QCL indicated by the first information, that is, the second indication information is used to indicate the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam.

[0122] In one implementation, the second indication information occupies one or more bits, and the value of the one or more bits is used to indicate the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam.

[0123] In some embodiments, the third field in the first message can be used to carry the second information. The third field can be located before or after the first field, between the first field and the second field, or between the information carried by the first field. Optionally, the content of the beam report includes the identification of the candidate beam and the beam measurement quality of the candidate beam, that is, the first field carries the identification of the candidate beam and the beam measurement quality of the candidate beam, and the third field can be the same as the second field and can be located between the identification of the candidate beam and the beam measurement quality of the candidate beam.

[0124] In an embodiment of the present application, the second information in the first message may indicate the effective duration of the QCL. The network device may further clarify the effective storage duration of the QCL stored in the terminal based on the second information, thereby facilitating flexible scheduling, such as issuing a TCI update instruction for scheduling, not scheduling, or extending the storage duration of the QCL as mentioned below.

[0125] After the QCL storage time of the reference signal reaches the valid time, the terminal may maintain the storage for a period of time without releasing the QCL. This period of time may be referred to as the extended storage time of the QCL.

[0126] In this regard, when the timing duration after the first message is sent is greater than or equal to the second duration, the terminal can release the QCL of the reference signal in the stored beam report, and the second duration is the sum of the effective duration of the QCL indicated by the second information and the extended storage duration of the QCL indicated by the first information.

[0127] In some embodiments, the effective duration of the QCL indicated by the second information may be determined by the terminal. For example, the terminal may determine the effective duration of the QCL according to a parameter table, which includes multiple effective durations of the QCL. The effective duration of the QCL indicated by the second information may also be configured by the network device to the terminal. Figure 4 and Figure 5 Introduce them separately.

[0128] Figure 4 The flowchart of another beam report reporting method provided in an embodiment of the present application is exemplified.

[0129] like Figure 4 As shown, the beam report reporting method provided in the embodiment of the present application includes:

[0130] S401: The network device sends RRC signaling to the terminal, and correspondingly, the terminal receives the RRC signaling.

[0131] The radio resource control (RRC) signaling includes a TCI status pool.

[0132] Exemplarily, the TCI state pool includes a set of TCI states, such as 128 or 256 TCI states, each TCI state includes a TCI state ID (i.e., a unique identifier), a QCL type (such as Type A, Type B, Type C, and Type D), and one or more downlink reference signals associated with the TCI state (such as CSI-RS, SSB), which can be used as a source reference signal for the QCL.

[0133] S402: The network device sends a MAC-CE to the terminal, and correspondingly, the terminal receives the MAC-CE.

[0134] The MAC-CE includes a TCI state subset to be activated.

[0135] The TCI state configured by the network device through RRC signaling is static. Therefore, the network device can activate a TCI state subset through MAC-CE, and the TCI state subset belongs to the TCI state subset to be activated.

[0136] For example, a network device may typically activate a TCI state subset, which may include multiple TCI states, such as eight TCI states. The multiple TCI states included in the TCI state subset to be activated typically belong to TCI states in a TCI state pool configured by the network device through RRC signaling.

[0137] S403. The network device sends SSB and / or CSI-RS to the terminal, and correspondingly, the terminal receives SSB and / or CSI-RS.

[0138] For a TCI state activated by a network device via MAC-CE, the network device may transmit a downlink reference signal associated with the TCI state, such as an SSB and / or CSI-RS. The downlink reference signal transmitted by the network device corresponds to a beam, meaning the network device transmits the downlink reference signal via a beam. For different TCI states, the terminal may use different beams to transmit the downlink reference signal associated with the TCI state.

[0139] In an example, TCI state A is associated with CSI-RS#1, and CSI-RS#1 is sent through beam B1; TCI state B is associated with CSI-RS#2, and CSI-RS#2 is sent through beam B2.

[0140] S404: The network device sends a parameter table to the terminal, and correspondingly, the terminal receives the parameter table.

[0141] The parameter table includes various effective durations of QCL. The network device sends the parameter table to the terminal, which facilitates the terminal to determine the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam based on the parameter table.

[0142] Optionally, the parameter table may further include second indication information corresponding to multiple effective durations of the QCL, that is, the parameter table may include multiple correspondences between the second indication information and the effective duration of the QCL. Exemplarily, the second indication information occupies one or more bits, and the value of one or more bits is 0, and the corresponding effective duration of the QCL is 100ms; the value of one or more bits is 1, and the corresponding effective duration of the QCL is 120ms. Based on this, the terminal can indicate the effective duration of the QCL of the reference signal corresponding to the most preferred beam through the second indication information, saving the number of bits occupied by the first message.

[0143] In some embodiments, the parameter table may be included in (i.e., carried by) RRC signaling, i.e., the network device sends RRC signaling to the terminal, and the RRC signaling includes the parameter table. Exemplarily, the RRC signaling carrying the parameter table may be a separate RRC signaling, or may be the RRC signaling sent by the network device in step S401, i.e., the network device sends RRC signaling to the terminal, and the RRC signaling includes the TCI status pool and the parameter table.

[0144] It can be understood that the network device has the advantage of greater flexibility when sending the parameter table through a separate RRC signaling, and the network device has the advantage of saving signaling by multiplexing the RRC signaling including the TCI status pool to send the parameter table.

[0145] Step S404 is an optional step. In some embodiments, the network device may not perform step S404.

[0146] S405. The terminal performs signal quality measurement based on the SSB and / or CSI-RS and obtains a beam report.

[0147] The terminal performs signal quality measurement (i.e., channel quality measurement) based on downlink reference signals such as SSB and / or CSI-RS sent by the network device, and obtains the L1-RSRP and / or L1-SINR of the downlink reference signal. The L1-RSRP and / or L1-SINR of the downlink reference signal can indicate the L1-RSRP or L1-SINR of the beam.

[0148] In the application scenario where the terminal initiates a beam report based on Event-7, the terminal determines whether the quality of a new beam reaches a threshold based on the L1-RSRP and / or L1-SINR of the beam. If the terminal determines that the quality of at least one new beam reaches the threshold, the terminal may generate a beam report. The description of the report content of the beam report can be found in the above content and will not be repeated here.

[0149] In application scenarios where the terminal performs beam measurement based on other events or UE-initiated beam measurement, the terminal may also obtain a beam report.

[0150] Optionally, after performing signal quality measurement, the terminal may also report a channel state information report configuration (CSI report configuration) to the network device. The CSI report configuration may include a channel quality indicator (CQI), a precoding matrix indicator (PMI), a rank indication (RI), etc., to assist the network device in optimizing downlink scheduling and beam management.

[0151] Based on the CSI report configuration, the network device can update the TCI state subset through MAC CE or downlink control information (DCI). The network device can send downlink reference signals associated with the TCI states in the updated TCI state subset. The terminal can also perform signal quality measurement based on the downlink reference signals sent by the network device to obtain the L1-RSRP or L1-SINR of the downlink reference signals and then generate a beam report.

[0152] After generating the beam report, the terminal may also store the QCL of the reference signal corresponding to the optimal candidate beam.

[0153] S406. The terminal sends a first message to the network device. Correspondingly, the network device receives the first message.

[0154] The first message includes a beam report, first information, and second information. The first information is used to indicate the QCL of the reference signal in the beam report stored by the terminal, and the second information is used to indicate the effective duration of the QCL indicated by the first information. The description of the first message, the first information, and the second information can be found in the above content and will not be repeated here.

[0155] In some embodiments, the terminal may independently determine the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam.

[0156] Exemplarily, the rule for the terminal to determine the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam may be: the effective duration of the QCL is positively correlated with the signal quality of the optimal candidate beam, that is, the better the signal quality of the optimal candidate beam, the longer the effective duration determined by the terminal as the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam.

[0157] Optionally, the terminal can determine the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam based on the signal quality of the optimal candidate beam. The effective duration of the QCL of the reference signal corresponding to the optimal candidate beam determined by the terminal can be used as the second information and carried in the first message.

[0158] In one implementation method, the terminal determines the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam based on the signal quality of the optimal candidate beam. Of course, the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam is positively correlated with the signal quality of the optimal candidate beam.

[0159] In another implementation method, the terminal receives a parameter table, which includes multiple effective durations of QCL. The terminal can determine the effective duration of QCL that is positively correlated with the signal quality of the optimal candidate beam from the parameter table based on the signal quality of the optimal candidate beam, and use it as the effective duration of QCL of the reference signal corresponding to the optimal candidate beam.

[0160] Optionally, the terminal may determine second indication information based on the signal quality of the optimal candidate beam, and the second indication information may indicate the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam. The second indication information may be carried in the first message as the second information.

[0161] In one implementation, the parameter table received by the terminal includes multiple correspondences between the effective duration of QCL and the second indication information. The terminal can determine the second indication information corresponding to the effective duration of QCL that is positively correlated with the signal quality of the optimal candidate beam from the parameter table as the second information based on the signal quality of the optimal candidate beam.

[0162] In one example, the parameter table includes multiple correspondences between the effective duration of the QCL and the second indication information as follows:

[0163] The second indication information is 0, and the corresponding QCL effective duration is 100ms;

[0164] The second indication information is 1, and the corresponding QCL effective duration is 120ms;

[0165] The second indication information is 2, and the corresponding QCL effective duration is 140ms...

[0166] The terminal determines that the signal quality of the optimal candidate beam is average according to step S405. Based on the parameter table, the terminal can select the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam as 100ms, and determine the second indication information to be 0, and carry it as the second information in the first message.

[0167] In the embodiment of the present application, the terminal independently determines the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam, which has the advantage of high flexibility.

[0168] It should be noted that after the terminal stores the QCL of the reference signal corresponding to the optimal candidate beam, it can control the QCL of the stored reference signal corresponding to the optimal candidate beam based on the effective duration of the QCL indicated by the second information.

[0169] Exemplarily, the moment when the terminal sends the first message is taken as the starting moment and the timing starts. During the valid duration of the QCL after the starting moment, the terminal continues to store the QCL of the reference signal corresponding to the optimal candidate beam. When the timing duration after the starting moment is greater than or equal to the first duration, the terminal can release the QCL of the reference signal corresponding to the optimal candidate beam. The first duration is the valid duration of the QCL indicated by the second information.

[0170] Optionally, before the terminal releases the QCL of the reference signal corresponding to the optimal candidate beam, it can determine that it has not received the scheduling of the network device, that is, it has not received the updated TCI state subset sent by the network device. It can be understood that: the network device can send an updated TCI state subset to the terminal for the beam report, and one TCI state in the updated TCI state subset can usually be associated with the downlink reference signal corresponding to the optimal candidate beam.

[0171] Optionally, within the valid duration of the QCL after the start time, the terminal receives scheduling from the network device, i.e., receives an updated TCI state subset sent by the network device. A TCI state in the updated TCI state subset is generally associated with a downlink reference signal corresponding to the optimal candidate beam. The terminal may use the stored QCL of the reference signal corresponding to the optimal candidate beam to receive the downlink reference signal corresponding to the optimal candidate beam. Optionally, the terminal may also clear a timer.

[0172] Figure 5 The flowchart of another beam report reporting method provided in an embodiment of the present application is exemplified.

[0173] like Figure 5 As shown, the beam report reporting method provided in the embodiment of the present application includes:

[0174] S501: The network device sends RRC signaling to the terminal, and correspondingly, the terminal receives the RRC signaling.

[0175] Among them, RRC signaling includes the TCI status pool.

[0176] The description of the RRC signaling can be found in the aforementioned step S401 and will not be repeated here.

[0177] S502: The network device sends a MAC-CE to the terminal, and correspondingly, the terminal receives the MAC-CE.

[0178] The MAC-CE includes a TCI state subset to be activated.

[0179] The description of MAC-CE can be found in the aforementioned step S402 and will not be repeated here.

[0180] S503. The network device sends SSB and / or CSI-RS to the terminal, and correspondingly, the terminal receives SSB and / or CSI-RS.

[0181] The description of step S503 can be found in the aforementioned step S403 and will not be repeated here.

[0182] S504: The network device sends the effective duration of the QCL to the terminal, and correspondingly, the terminal receives the effective duration of the QCL.

[0183] The network device can maintain the validity period of the QCL stored in the terminal, and the network device can configure the validity period of the QCL for the terminal to enable the terminal to control the stored QCL based on the configuration of the network device.

[0184] In some embodiments, the effective duration of the QCL may be included in (i.e., carried by) RRC signaling, i.e., the network device sends RRC signaling to the terminal, and the RRC signaling includes the effective duration of the QCL. Exemplarily, the RRC signaling carrying the effective duration of the QCL may be a separate RRC signaling, or may be the RRC signaling sent by the network device in step S501, i.e., the network device sends RRC signaling to the terminal, and the RRC signaling includes the TCI status pool and the effective duration of the QCL.

[0185] It can be understood that the network device sending the effective duration of QCL through a separate RRC signaling has the advantage of greater flexibility, and the network device multiplexing the effective duration of QCL including the RRC signaling of the TCI status pool has the advantage of saving signaling.

[0186] S505. The terminal performs signal quality measurement based on the SSB and / or CSI-RS and obtains a beam report.

[0187] The description of step S505 can be found in the aforementioned step S405 and will not be repeated here.

[0188] S506: The terminal sends a first message to the network device, and correspondingly, the network device receives the first message.

[0189] The first message includes a beam report and first information, and the first information is used to indicate the QCL of the reference signal in the beam report stored by the terminal.

[0190] The description of the first message and the first information can be found in the above content and will not be repeated here.

[0191] The terminal can also use the effective duration of the QCL configured by the network device to control the QCL of the reference signal corresponding to the stored optimal candidate beam. The implementation method of the terminal controlling the QCL of the reference signal corresponding to the stored optimal candidate beam can be found in the content of the aforementioned embodiment and will not be repeated here.

[0192] The network device may configure the extended storage duration of the QCL to the terminal. For example, the network device may configure the extended storage duration of the QCL to the terminal via a second message. The second message may include third information indicating the extended storage duration of the QCL indicated by the first information.

[0193] Optionally, the manner in which the third information indicates the extended storage time of the QCL indicated by the first information may be: the third information includes third indication information, and the third indication information is used to indicate the extended storage time of the QCL indicated by the first information. Correspondingly, the network device may configure a parameter table to the terminal, and the extended storage time of the QCL may be determined by the terminal according to the parameter table. Exemplarily, the parameter table includes multiple extended storage times of the QCL and corresponding third indication information.

[0194] Optionally, the third information may indicate the extended storage time of the QCL indicated by the first information in the following manner: the third information includes the extended storage time of the QCL indicated by the first information.

[0195] The following combination Figure 6 and Figure 7 Introduce them separately.

[0196] Figure 6 The flowchart of another beam report reporting method provided in an embodiment of the present application is exemplified.

[0197] like Figure 6 As shown, the beam report reporting method provided in the embodiment of the present application includes:

[0198] S601: The network device sends RRC signaling to the terminal, and correspondingly, the terminal receives the RRC signaling.

[0199] Among them, RRC signaling includes the TCI status pool.

[0200] The description of the RRC signaling can be found in the aforementioned step S401 and will not be repeated here.

[0201] S602: The network device sends a MAC-CE to the terminal, and correspondingly, the terminal receives the MAC-CE.

[0202] The MAC-CE includes a TCI state subset to be activated.

[0203] The description of MAC-CE can be found in the aforementioned step S402 and will not be repeated here.

[0204] S603. The network device sends SSB and / or CSI-RS to the terminal, and correspondingly, the terminal receives SSB and / or CSI-RS.

[0205] The description of step S603 can be found in the aforementioned step S403 and will not be repeated here.

[0206] S604: The network device sends a parameter table to the terminal, and correspondingly, the terminal receives the parameter table.

[0207] The parameter table includes various effective durations of QCL, and the parameter table can be called a first parameter table.

[0208] The description of step S604 can be found in the aforementioned step S404 and will not be repeated here.

[0209] Step S604 is an optional step. In some embodiments, the network device may not perform step S604.

[0210] In some embodiments, the network device may also send a second parameter table to the terminal, which may include third indication information corresponding to multiple extended storage times of QCL, that is, the second parameter table includes multiple correspondences between the third indication information and the extended storage time of QCL.

[0211] Exemplarily, the third indication information occupies one or more bits. If the value of one or more bits is 0, the corresponding extended storage duration of the QCL is 50 ms. If the value of one or more bits is 1, the corresponding extended storage duration of the QCL is 80 ms. Based on this, the network device can use the third indication information to indicate the extended storage duration of the QCL of the reference signal corresponding to the most preferred beam, thereby saving the number of bits occupied by the second message.

[0212] Optionally, the second parameter table may also be the same parameter table as the first parameter table, that is, the network device configures a parameter table to the terminal, which parameter table may include multiple valid durations of QCL or multiple correspondences between the second indication information and the valid duration of QCL, and may also include multiple correspondences between the third indication information and the extended storage duration of QCL.

[0213] Optionally, the second parameter table and the first parameter table may also be two independent parameter tables.

[0214] In some embodiments, the second parameter table may also be included in (i.e., carried by) RRC signaling. Exemplarily, the second parameter table and the first parameter table are included in one RRC signaling, or included in different RRC signaling. The RRC signaling may be a separate RRC signaling, or it may be an RRC signaling sent by the network device through step S601, that is, the network device sends RRC signaling to the terminal, and the RRC signaling includes the TCI status pool, the second parameter table, and the first parameter table.

[0215] S605. The terminal performs signal quality measurement based on the SSB and / or CSI-RS and obtains a beam report.

[0216] The description of step S605 can be found in the aforementioned step S405 and will not be repeated here.

[0217] S606: The terminal sends a first message to the network device. Correspondingly, the network device receives the first message.

[0218] The first message includes a beam report, first information, and second information. The first information is used to indicate the QCL of the reference signal in the beam report stored by the terminal, and the second information is used to indicate the effective duration of the QCL indicated by the first information.

[0219] After receiving the first message, the network device has the following three options:

[0220] The network device executes step S607a, or executes step S607b, or does not perform scheduling, and the terminal determines that the timing duration after sending the first message is greater than or equal to the first duration, and executes step S607c.

[0221] S607a: The network device sends a TCI update signaling to the terminal. Correspondingly, the terminal receives the TCI update signaling.

[0222] The network device may send TCI update signaling to the terminal in response to the beam report. The terminal may receive the TCI update signaling within the valid duration of the QCL after sending the first message. Exemplarily, the TCI update signaling includes an updated TCI state subset. A TCI state in the updated TCI state subset may typically be associated with a downlink reference signal corresponding to the optimal candidate beam.

[0223] Optionally, after receiving the TCI update signaling, the terminal can use the QCL of the reference signal corresponding to the stored optimal candidate beam to receive the downlink reference signal corresponding to the optimal candidate beam.

[0224] Optionally, after receiving the TCI update signaling, the terminal may clear the timer.

[0225] In some embodiments, the TCI update signaling may be included in (ie, carried by) a MAC-CE, but this is not a limitation.

[0226] S607b: The network device sends a second message to the terminal, and correspondingly, the terminal receives the second message.

[0227] The second message includes third information, and the third information is used to indicate the extended storage time of the QCL indicated by the first information.

[0228] In some embodiments, the second message is a MAC CE. Optionally, the second message may reuse the format of a TCI state activation / deactivation MAC-CE. For example, the MAC CE may include a serving cell ID, the third information, and the TCI state corresponding to the QCL stored by the terminal. The TCI state may be indicated by the TCI state ID.

[0229] In one implementation, the third information may occupy one or more bits, such as 4 bits.

[0230] In other embodiments, the second message is a DCI. Optionally, the second message is DCI1_0, and the third information may be carried in DCI1_0 by inserting padding bits. For example, DCI1_0 includes a frequency domain resource assignment field, and the third information is also located after the frequency domain resource assignment field, occupying one or more bits.

[0231] In the second message, the third information indicates that the implementation method of extending the storage time of the QCL indicated by the first information can be as described above.

[0232] Exemplarily, the third information is third indication information, which indicates the extended storage time of the QCL indicated by the first information. When the terminal receives the second message, it can determine the extended storage time of the QCL corresponding to the third indication information in the second message in the second parameter table. The terminal can wait for scheduling by the network device within the combined time (i.e., the second time) of the effective time of the QCL and the extended storage time after sending the beam report.

[0233] As another example, the third information is the extended storage time of the QCL indicated by the first information. When the terminal receives the second message, it can use the third information in the second message to determine the extended storage time of the QCL indicated by the first information, and wait for scheduling by the network device within the combined time (i.e., the second time) of the effective time of the QCL and the extended storage time after sending the beam report.

[0234] Optionally, the terminal receives scheduling from the network device within the second time period, that is, receives TCI update signaling sent by the network device through step S608a, and can use the QCL of the reference signal corresponding to the stored optimal candidate beam to receive the downlink reference signal corresponding to the optimal candidate beam.

[0235] Optionally, if the terminal does not receive the scheduling of the network device within the second time period, the terminal may execute the following step S608b when the timing time after the first message is sent is greater than or equal to the second time period.

[0236] In some embodiments, the network device may send a second message within Y time slots after receiving the first message, where Y is a positive integer greater than or equal to 1. It can be understood that the network device may send the second message within the first time length after the terminal sends the first message.

[0237] In other embodiments, the network device may send one or more second messages to instruct the terminal to extend the storage QCL one or more times. The extended storage duration is indicated by third information in the second message.

[0238] S608a: The network device sends TCI update signaling to the terminal, and correspondingly, the terminal receives the TCI update signaling.

[0239] The description of the TCI update signaling can be found in the aforementioned step S607a, which will not be repeated here.

[0240] S608b: The terminal releases the stored QCL of the reference signal.

[0241] The terminal releasing the stored QCL of the reference signal may be understood as deleting the stored QCL of the reference signal.

[0242] S607c: The terminal releases the stored QCL of the reference signal.

[0243] If the terminal does not receive the second message sent by the network device or the scheduling of the network device within the first time period after sending the first message, the QCL of the stored reference signal can be released through step S607c, which can avoid the problem that the QCL stored in the terminal is ineffective and not released, resulting in the invalid occupation of the terminal's memory resources.

[0244] Figure 7 The flowchart of another beam report reporting method provided in an embodiment of the present application is exemplified.

[0245] like Figure 7 As shown, the beam report reporting method provided in the embodiment of the present application includes:

[0246] S701: The network device sends RRC signaling to the terminal, and correspondingly, the terminal receives the RRC signaling.

[0247] Among them, RRC signaling includes the TCI status pool.

[0248] The description of the RRC signaling can be found in the aforementioned step S401 and will not be repeated here.

[0249] S702: The network device sends a MAC-CE to the terminal, and correspondingly, the terminal receives the MAC-CE.

[0250] The MAC-CE includes a TCI state subset to be activated.

[0251] The description of MAC-CE can be found in the aforementioned step S402 and will not be repeated here.

[0252] S703. The network device sends SSB and / or CSI-RS to the terminal, and correspondingly, the terminal receives SSB and / or CSI-RS.

[0253] The description of step S703 can be found in the aforementioned step S403 and will not be repeated here.

[0254] S704: The network device sends the valid duration and extended storage duration of the QCL to the terminal. Correspondingly, the terminal receives the valid duration and extended storage duration of the QCL.

[0255] The network device can maintain the effective duration and extended storage duration of the QCL stored in the terminal. For example, the network device stores multiple sets of effective durations and extended storage durations of QCL. The network device can select one set of effective durations and extended storage durations and configure them to the terminal.

[0256] Optionally, the network device stores a range of the effective duration of QCL and a range of extended storage duration, such as a range of effective duration of 100-200ms and a range of extended storage duration of 0-100ms. The network device can select a value in the range of effective duration and a value in the extended storage duration, and configure them to the terminal.

[0257] Network devices can configure the validity period and extended storage period of QCL for terminals, so that terminals can manage and control stored QCL based on the configuration of network devices, reducing the complexity of terminal operations.

[0258] S705. The terminal performs signal quality measurement based on the SSB and / or CSI-RS and obtains a beam report.

[0259] The description of step S705 can be found in the aforementioned step S405 and will not be repeated here.

[0260] S706: The terminal sends a first message to the network device. Correspondingly, the network device receives the first message.

[0261] The first message includes a beam report and first information, and the first information is used to indicate the QCL of the reference signal in the beam report stored by the terminal.

[0262] The description of the first message and the first information can be found in the above content and will not be repeated here.

[0263] After receiving the first message in step S706, the network device may send TCI update signaling within the valid duration of the QCL, or may send TCI update signaling within the extended storage duration after the valid duration of the QCL.

[0264] It can be understood that the network device sends the valid duration and extended storage duration of QCL to the terminal through step S704. In this way, the network device and the terminal synchronize the valid duration and extended storage duration of QCL. After receiving the first message, the network device can decide whether to perform scheduling and the scheduling timing based on the beam report of the first message, that is, whether to send a TCI update instruction, and whether to send TCI update signaling within the valid duration of QCL, or to send TCI update signaling within the extended storage duration after the valid duration of QCL.

[0265] S707a: The network device sends a TCI update signaling to the terminal within the valid duration of the QCL. Correspondingly, the terminal receives the TCI update signaling.

[0266] The description of the TCI update signaling can be found in the aforementioned step S607a, which will not be repeated here.

[0267] S707b: The network device sends a TCI update signaling to the terminal within the extended storage time of the QCL. Correspondingly, the terminal receives the TCI update signaling.

[0268] The description of the TCI update signaling can be found in the aforementioned step S607a, which will not be repeated here.

[0269] S707c: When the timing duration after sending the first message is greater than or equal to the second duration, the terminal releases the stored QCL of the reference signal.

[0270] The second duration is the sum of the effective duration of the QCL and the extended storage duration of the QCL.

[0271] In some embodiments, after receiving the first message, the network device may also send one or more second messages to the terminal, further indicating the extended storage duration of the QCL to the terminal through third information in the second message. Correspondingly, the terminal may receive the second message.

[0272] Exemplarily, when the timing duration after the first message is sent is less than or equal to the valid duration of the QCL, the terminal receives the second message, and the terminal continues to store the QCL after the timing duration reaches the valid duration of the QCL, and the storage duration is the extended storage duration of the QCL indicated by the third information in the second message, instead of managing and controlling the QCL according to the extended storage duration of the QCL sent by the network device through step S704, that is, the extended storage duration of the QCL indicated by the third information in the second message is used to replace (i.e., update) the extended storage duration of the QCL previously sent by the network device.

[0273] Alternatively, after the timing duration reaches the valid duration of the QCL, the terminal may continue to store the QCL until the timing duration reaches the extended storage duration of the QCL sent by the network device in step S704. The terminal may continue to store the QCL, and the storage duration is the extended storage duration of the QCL indicated by the third information in the second message. In other words, the extended storage duration of the QCL indicated by the third information in the second message is the further extended storage duration of the QCL stored by the terminal, that is, it is used to instruct the terminal to continue to store the QCL based on the extended storage duration of the QCL indicated by the third information after the timing duration after sending the first message is equal to the sum of the valid duration of the QCL and the extended storage duration.

[0274] While storing the QCL based on the extended QCL storage duration indicated by the third information, the terminal may wait for scheduling by the network device, that is, wait for a TCI update instruction sent by the network device. The implementation of the network device sending the TCI update instruction and the terminal's actions after receiving the TCI update instruction are described above and are not further described here.

[0275] After the terminal stores the QCL based on the extended storage duration of the QCL indicated by the third information and the QCL expires, the terminal can release the QCL. For details, please refer to the above content and will not be repeated here.

[0276] As another example, when the timing duration after the first message is sent is greater than the valid duration of the QCL but less than or equal to the valid duration and extended storage duration of the QCL, the terminal receives a second message. The terminal continues to store the QCL after the timing duration reaches the valid duration and extended storage duration of the QCL, and the storage duration is the extended storage duration of the QCL indicated by the third information in the second message.

[0277] Similarly, while storing the QCL based on the extended QCL storage duration indicated by the third information, the terminal may wait for scheduling by the network device, that is, wait for a TCI update instruction sent by the network device. The implementation of the network device sending the TCI update instruction and the actions of the terminal after receiving the TCI update instruction are described above and are not further described here.

[0278] After the terminal stores the QCL based on the extended storage duration of the QCL indicated by the third information and the QCL expires, the terminal can release the QCL. For details, please refer to the above content and will not be repeated here.

The first information is used to indicate the quasi-co-site QCL of the reference signal in the beam report stored by the terminal, and the second information is used to indicate the valid duration of the QCL indicated by the first information. The valid duration of the QCL indicated by the first information is used to indicate that the timing duration after the first message is sent is greater than or equal to the valid duration, and the QCL of the reference signal in the stored beam report is released.

[0289] For example, the communication module 820 is also used to send a second message, the second message includes third information, the third information is used to indicate the extended storage time of the QCL indicated by the first information, the extended storage time of the QCL is used to indicate that when the timing time after the first message is sent is greater than or equal to the second time, the QCL of the reference signal in the stored beam report is released, and the second time is the sum of the effective time of the QCL indicated by the first information and the extended storage time of the QCL indicated by the first information.
