Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, and particularly relates to a reporting method of a beam report and related devices. BACKGROUND

[0002] In a beam management procedure, a terminal can report a beam report based on a UE-initiated / event-driven trigger, so as to reduce uplink report overhead and control signaling overhead.

[0003] In one application scenario, the terminal reports a beam report based on an Event-7 trigger, and a feature of the Event-7 determination is that the quality of at least one new beam reaches a threshold value, and the terminal can initiate a beam report based on the Event-7. In addition, after the terminal initiates the beam report, the terminal can also store quasi-co-location (QCL) of a reference signal in a reported beam.

[0004] However, the beam report reported by the terminal based on the Event-7 includes information of multiple candidate beams, and the quality of the multiple candidate beams may not all reach the threshold value, and the terminal can store the QCL of the reference signal of the beam whose quality reaches the threshold value. Therefore, the network device cannot determine the beam to which the QCL stored by the terminal belongs through the beam report reported by the terminal, and thus cannot perform adaptive scheduling. SUMMARY

[0005] The present application provides a reporting method of a beam report and related devices, and aims to enhance adaptive scheduling beams of a network device.

[0006] In order to achieve the above-mentioned purpose, the present application provides the following technical solutions:

[0007] In a first aspect, the present application provides a reporting method of a beam report, which can be executed by a terminal, or can be executed by a component (such as a circuit, a chip or a chip system, etc.) configured in the terminal, and can also be implemented by a logic module or software which can implement all or part of the terminal functions. The present application does not make any limitation in this regard. The following will be described taking the terminal as an example.

[0008] The reporting method of the beam report comprises: sending a first message, the first message comprising the beam report, first information and second information, the first information being used for indicating the QCL of the reference signal in the stored beam report of the terminal, and the second information being used for indicating the valid time length of the QCL indicated by the first information; in a case where the timing time length after the sending of the first message is greater than or equal to a first time length, releasing the QCL of the reference signal in the stored beam report, the first time length being the valid time length of the QCL indicated by the second information, or in a case where the timing time length after the sending of the first message is greater than or equal to a second time length, releasing the QCL of the reference signal in the stored beam report, the second time length being the sum of the valid time length of the QCL indicated by the second information and the extended storage time length 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 for indicating the QCL of the reference signal in the stored beam report of the terminal, the network device can determine the beam to which the QCL stored by the terminal belongs based on the first information in the first message, that is, determine which beam the QCL of the reference signal stored by the terminal belongs to, and can perform adaptive scheduling based on the QCL stored by the terminal, thereby enhancing the ability of the network device to adaptively schedule beams. Further, the QCL stored by the terminal can be scheduled in time by the network device, thereby avoiding the problem of invalid occupation of memory resources caused by the QCL stored by the terminal being invalid due to not being used in time. Still further, the second information in the first message can indicate the valid time length of the QCL, and the network device can further determine the valid storage time length of the QCL stored by the terminal based on the second information, thereby facilitating flexible scheduling.

[0010] Optionally, during the period when the timing time length after the sending of the first message does not reach (i.e., is less than) the first time length, the terminal does not receive the scheduling of the network device, that is, the terminal does not receive the scheduling of the network device within the first time length after the sending of the first message, and the terminal releases the QCL of the reference signal in the stored beam report when the timing time length after the sending of the first message is greater than or equal to the first time length. In this way, the terminal can release the stored QCL of the reference signal to avoid the invalid occupation of the memory resources of the terminal caused by the QCL stored by the terminal not working and not being released.

[0011] Optionally, during the period when the timing time length after the sending of the first message does not reach (i.e., is less than) the second time length, the terminal does not receive the scheduling of the network device, and optionally also does not receive the indication message of the delayed storage of the QCL. In this way, the terminal can also release the stored QCL of the reference signal to avoid the invalid occupation of the memory resources of the terminal caused by the QCL stored by the terminal not working and not being released.

[0012] In a possible implementation, the first information includes first indication information or 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 a possible implementation, the second information includes second indication information or a valid time length of the QCL indicated by the first information, and the second indication information is used to indicate the valid time length of the QCL indicated by the first information.

[0014] In a possible implementation, the valid time length of the QCL indicated by the second information is determined according to a parameter table or configured by the network device, and the parameter table includes multiple valid time lengths of the QCL.

[0015] In a possible implementation, the reporting method of 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 time length of the QCL indicated by the first information. Optionally, after the terminal receives the second message, if a timing time length after sending the first message is greater than or equal to a first time length, the terminal does not release the QCL of the reference signal in the stored beam report, and if the timing time length after sending the first message is greater than or equal to a second time length, the terminal releases the QCL of the reference signal in the stored beam report.

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

[0060] For example,Figure 1 A schematic diagram of an architecture of a communication system is shown.

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

[0062] The first device 100 can be a device for providing network communication function on the network side, and is also called network device or network element in some cases. The network device can be a base station (including a functional unit of the base station or a combination of functional units of the base station) or a core network unit in general, where 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 embodiments of the present application, the base station can be any device with wireless transceiving function, including but not limited to: an evolved Node B (eNB or e-NodeB) in long term evolution (LTE), a base station (gNodeB or gNB) or a transmission receiving point (TRP) in new radio (NR), a base station in 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-sited or non-co-sited transmission reception points (TRPs). 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 an LTE network, and can also communicate with a base station supporting a 5G network, and can also communicate with a base station supporting an LTE network and a base station supporting a 5G network in dual connectivity.

[0064] In actual application, the network device, as an access network device, can be cooperated by multiple network devices to assist the terminal to implement wireless access, and different network devices respectively implement part of functions of a base station. For example, the network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be separately arranged, or can be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna processing unit (AAU), or a remote radio head (RRH).

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

[0066] Figure 2 A structural schematic diagram of an access network device. As an implementation example, as shown in FIG. 1, the network device can include a central unit (CU) and a distributed unit (DU). The CU can be connected to the DU through an optical fiber or a cable, and the CU and the DU can be connected through an air interface to a terminal (or a user equipment, UE). The CU can be connected to a core network device (or a core network element, such as a mobile management entity (MME) or an access and mobility management function (AMF)) through an optical fiber or a cable. The CU can be connected to a radio unit (RU) through an optical fiber or a cable, and the RU can be connected to the terminal through an air interface. Figure 2As shown, the access network device can include at least one CU and at least one DU. This design can be referred to as CU and DU separation. One CU can be connected with one or more DUs. The CU and the DU can be divided according to protocol layers of the wireless network: for example, functions of a PDCP layer and above protocol layers (for example, an RRC layer and an SDAP layer, etc.) are arranged at the CU, and functions of protocol layers below the PDCP layer (for example, an RLC layer, a media access control (MAC) layer, and a PHY layer, etc.) are arranged at the DU; for another example, functions of the PDCP layer and above protocol layers are arranged at the CU, and functions of the PDCP layer and below protocol layers are arranged at the DU, without limitation. When the CU includes a CU-CP and a CU-UP, the CU-CP is configured to implement control plane functions of the CU, and the CU-UP is configured to implement user plane functions of the CU. For example, the CU is configured to implement functions of the PDCP layer, the RRC layer, and the SDAP layer, the CU-CP is configured to implement functions of the RRC layer and control plane functions of the PDCP layer, and the CU-UP is configured to implement functions of the SDAP layer and user plane functions of the PDCP layer. The name of the CU and the DU is not limited in the present application. The above-mentioned division of processing functions of the CU and the DU according to protocol layers is only an example, and the division can also be performed in other manners.

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

[0068] Further, part of functions of the DU can be separately arranged. For example, Figure 2As shown, the part of the functions can be implemented by a radio unit (RU). The RU can have radio frequency functions. The name of the RU is not limited in the present application. The DU and the RU can be split or separated at the PHY layer. For example, the DU can implement high layer functions in the PHY layer, and the RU can implement low layer functions in the PHY layer or implement the low layer functions and the radio frequency functions. The high layer functions in the PHY layer include functions closer to the MAC layer, and the low layer functions in the PHY layer include functions closer to the radio frequency. For example, the high layer functions of the PHY layer include one or more of the following: forward error correction (FEC) encoding / decoding, scrambling, or modulation / demodulation. The low layer functions of the PHY layer include one or more of the following: fast Fourier transform (FFT) / inverse fast Fourier transform (IFFT), beamforming, or extraction and filtering of a physical random access channel (PRACH), and the like. The RU can communicate radio frequency signals with the terminal device through an air interface. The pre-coding function of the PHY layer code can be located in the DU or in the RU. The split manner between the DU and the RU can be various possible manners and is not limited. There is an interface between the DU and the RU. For example, according to different split manners, the interface between the DU and the RU can be a common public radio interface (CPRI) interface or an enhanced common public radio interface (eCPRI) interface.

[0069] Optionally, any of the above CU, CU-CP, CU-UP, DU, and RU can be a software module, a hardware structure, or a software module plus a hardware structure, and is not limited. The forms of existence of different entities can be the same or different. For example, the CU, the CU-CP, the CU-UP, and the DU are software modules, and the RU is a hardware structure. For the sake of brevity of description, all possible combination forms are not listed one by one here. The modules and the methods performed thereby are also within the protection scope of the embodiments of the present application. For example, when the method of the embodiments of the present application is performed by an access network device, the method can be specifically performed by at least one of the CU, the CU-CP, the CU-UP, the DU, or the RU.

[0070] The second device 200 can be a device of an access network and can generally be a terminal.

[0071] In the embodiments of the present application, the terminal can be 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, and the like. The terminal can also be referred to as a terminal device, a user equipment (UE), an access terminal device, a vehicle-mounted terminal, an industrial control terminal, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal device, a mobile device, a UE terminal device, a wireless communication device, a UE agent, or a UE apparatus, and the like. The terminal can also be a fixed terminal or a mobile terminal.

[0072] In some embodiments, the communication system can further include other devices in communication with the first device and / or the second device, which are not limited herein.

[0073] For ease of understanding, the concepts involved in the present application are first described below.

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

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

[0076] 3. Beamforming:

[0077] The network device can interact with the terminal through the beamforming technology. The network device can usually form multiple downlink (DL) transmission beams, and in one or more DL transmission beams, the terminal in the coverage range of the beam can be sent downlink signals, and the terminal in the coverage range of the beam can receive the downlink signals through the beam.

[0078] 4、Synchronization Signal Block (SS / PBCH block, SSB), SSB opportunity, slot

[0079] In the NR system, one SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcast channel (PBCH) for implementing cell initial access, time-frequency synchronization, and measurement functions. SSB is transmitted through multiple beams, and the terminal selects the best beam access by measuring the SSB signal strength of different beams.

[0080] Transmitting one SSB occupies a certain time domain symbol, so the resource for transmitting one SSB is called a candidate SSB opportunity, simply referred to as SSB opportunity.

[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 at most two SSBs, which are located in different groups of time domain symbols in the slot. That is, a slot includes at most 2 SSB opportunities.

[0082] 5、Quasi-Co-Location (QCL)

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

[0084] 6、Transmission Configuration Indicator State (TCI State)

[0085] TCI state is a core mechanism for configuring the quasi-co-location relationship (QCL) between downlink reference signals and data channels. TCI state is a set of network configuration parameters used to describe the QCL relationship between downlink reference signals (such as SSB, channel state information reference signal (CSI-RS)) and data channels (such as PDSCH / PDCCH DMRS).

[0086] Each TCI state can contain 1 or 2 downlink reference signals (such as SSB or CSI-RS) and specify a QCL type (Type A / B / C / D) for each reference signal, which indicates the channel parameters that the data channel can obtain from the reference signal.

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

[0088] Wherein, the related introduction of PDSCH, PDCCH, beamforming, SSB, SSB opportunity, time slot, QCL and TCI state, etc. is only for the convenience of understanding the technical solutions of the present application, and does not constitute any limitation on the present application.

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

[0090] For example, the Event-7 triggered beam report is the UEI / ED triggered beam management, and the feature of Event-7 determination is that the quality of at least one new beam reaches a threshold value, and the terminal can initiate the Event-7 based beam report. Moreover, after the terminal initiates the beam report, the QCL of the reference signal in the reported beam can also be stored, so as to reduce the beam application delay. In the following, the new beam with the quality reaching the threshold value is referred to as the best quality beam, the optimal candidate beam, etc., but this does not constitute a limitation.

[0091] However, after the terminal initiates the Event-7 based beam report and stores the QCL of the reference signal in the reported beam, if the network device makes a decision not to update, the QCL stored by the terminal will not work and will not be released, resulting in invalid occupation of the memory resources of the terminal.

[0092] Further, the beam report reported by the terminal based on the event-7 includes information of multiple candidate beams, and the quality of the multiple candidate beams can not all reach the threshold, and the terminal can store the QCL of the reference signal of the beam whose quality reaches the threshold. Therefore, the network device cannot determine the beam to which the QCL stored by the terminal belongs through the beam report reported by the terminal, that is, cannot determine which reference signal of the beam the terminal stores the QCL of, and thus cannot perform adaptive scheduling. Further, the network device cannot perform adaptive scheduling, and the QCL stored by the terminal can be invalid due to not being used in time, and the invalid QCL also occupies the memory resource of the terminal, causing the memory resource to be invalidly occupied.

[0093] To this end, the embodiment of the present application provides a reporting method of a beam report, which can enhance the adaptive scheduling beam of the network device.

[0094] Figure 3 An exemplary flowchart of the reporting method of the beam report provided by the embodiment of the present application is shown.

[0095] As shown in Figure 3 The reporting method of the beam report provided by the embodiment of the present application includes the following steps.

[0096] S301, the terminal sends a first message to the network device, and 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 the UCI to the network device, and the UCI can include the reporting content of the beam report and the first information.

[0099] In other embodiments, the first message is a MAC control element (MAC CE). That is, the terminal sends the MAC CE to the network device, and the MAC CE can include the reporting content of the beam report and the first information.

[0100] Exemplarily, the reporting content of the beam report includes information of multiple candidate beams, wherein the multiple candidate beams include a best quality beam (i.e., an optimal candidate beam) and other candidate beams.

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

[0102] Optionally, the information of the other candidate beams can comprise: an identity of the candidate beam, such as an SSBRI and / or a CRI; and a beam measurement quality of the candidate beam, such as an L1-RSRP and / or an L1-SINR. Optionally, the information of the other candidate beams can further comprise: an identity of the candidate beam, and a difference between the beam measurement quality of the other candidate beam and the beam measurement quality of the optimal candidate beam, such as a difference between an L1-RSRP of the other candidate beam and an L1-RSRP of the optimal candidate beam.

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

[0104] For example, the QCL of the reference signal in the beam report stored by the terminal is a QCL of a reference signal (such as a CSI-RS or an 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 of the first information used to indicate the QCL of the reference signal in the beam report stored by the terminal comprises: the first information comprises the QCL of the reference signal in the beam report stored by the terminal, i.e., the first information comprises the QCL of the reference signal corresponding to the optimal candidate beam.

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

[0107] In an implementation, the first indication information occupies one or more bits, and a 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 can be used to carry the beam report, and the second field can be used to carry the first information. For example, the second field can be located before or after the first field; for another example, the second field can be located between the information carried by the first field, and optionally, the content of the beam report includes the identification of the candidate beam and the beam measurement quality of the candidate beam, i.e., the first field carries the identification of the candidate beam and the beam measurement quality of the candidate beam, and the second field can be located between the identification of the candidate beam and the beam measurement quality of the candidate beam.

[0109] In another embodiment, the terminal generates the beam report, and after storing the QCL of the reference signal corresponding to the optimal candidate beam, the terminal sends the first message to the network device.

[0110] In the embodiments 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, and the network device can determine the beam to which the QCL stored by the terminal belongs based on the first information in the first message, i.e., determine which beam the QCL of the reference signal stored by the terminal belongs to, and can perform adaptive scheduling based on the QCL stored by the terminal, thereby enhancing the ability of the network device to perform adaptive scheduling of the beam. Moreover, the QCL stored by the terminal can be scheduled in time by the network device, thereby avoiding invalid occupation of the memory resource due to the fact that the QCL stored by the terminal is not used in time.

[0111] In another embodiment, the first message can further include second information, and the second information is used to indicate the valid time length of the QCL indicated by the first information (or the stored valid time length). Based on this, the first message includes the beam report, the first information, and the second information.

[0112] Optionally, in the case where the time length after the sending of the first message is greater than or equal to the first time length, the terminal can release the QCL of the reference signal in the stored beam report, the first time length is the valid time length of the QCL indicated by the second information, and the QCL is indicated by the first information, and the second time length is the valid time length of the QCL indicated by the first information indicated by the second information.

[0113] Alternatively, in a case that the timing duration after the sending of the first message is greater than or equal to the second duration, the terminal can release the QCL of the reference signal in the stored beam report, the second duration being a 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 effective duration of the QCL refers to a limited duration of the QCL indicated by the first information, and the terminal can release the QCL indicated by the first information if the duration of the QCL stored by the terminal is greater than or equal to the effective duration.

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

[0116] The release of the QCL indicated by the first information can be understood as deleting the QCL indicated by the first information.

[0117] In an implementation, the terminal does not receive scheduling of the network device within a first duration after the sending of the first message (i.e., during a period in which the terminal counts a duration after the sending of the first message and the duration is less than the first duration), and the terminal can release the QCL of the reference signal in the stored beam report when the timing duration after the sending of the first message is greater than or equal to the first duration.

[0118] In another implementation, the terminal receives scheduling of the network device within the first duration after the sending of the first message, and the stored QCL can be used to receive the downlink reference signal corresponding to the candidate beam.

[0119] In a case that the duration of the QCL stored by the terminal is greater than or equal to the effective duration, the terminal releases the stored QCL, which can avoid invalid occupation of the memory resource of the terminal caused by the QCL stored by the terminal and not released.

[0120] Optionally, the implementation in which the second information indicates the effective duration of the QCL indicated by the first information can be that the second information includes the effective duration of the QCL of the reference signal corresponding to the optimal candidate beam.

[0121] Alternatively, the implementation in which the second information indicates the effective duration of the QCL indicated by the first information can also be that 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, i.e., 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 an implementation, the second indication information occupies one or more bits, and a value of the one or more bits is used to indicate the effective time length 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, or between the first field and the second field, or between the information carried by the first field, and 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 located between the identification of the candidate beam and the beam measurement quality of the candidate beam, which is the same as the second field.

[0124] In the embodiments of the present application, the second information in the first message can indicate the effective time length of the QCL, and the network device can further determine the effective storage time length of the QCL stored by the terminal based on the second information, so as to facilitate flexible scheduling, such as the scheduling mentioned below by issuing a TCI update instruction, not scheduling, or extending the storage time length of the QCL.

[0125] After the time length of the terminal storing the QCL of the reference signal reaches the effective time length, the terminal can maintain the storage for a period of time without releasing, which can be referred to as the extended storage time length of the QCL.

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

[0127] In some embodiments, the effective time length of the QCL indicated by the second information can be determined by the terminal, for example, the terminal can determine the effective time length of the QCL according to a parameter table, and the parameter table includes a plurality of effective time lengths of the QCL; the effective time length of the QCL indicated by the second information can also be configured by the network device to the terminal. The following Figure 4 and Figure 5 are introduced respectively.

[0128] Figure 4 An exemplary flowchart of another reporting method of a beam report provided by the embodiments of the present application is shown.

[0129] As Figure 4 shown, the reporting method of the beam report provided by the embodiments 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 state pool.

[0132] The TCI state pool includes a set of TCI states, such as 128 or 256 TCI states, each TCI state including 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 (such as CSI-RS, SSB) associated with the TCI state, which can be used as a source reference signal for QCL.

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

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

[0135] The TCI states configured by the network device through RRC signaling are static, and therefore, the network device can activate a subset of TCI states through a MAC-CE, which belongs to the subset of TCI states to be activated.

[0136] The network device can usually activate one subset of TCI states, which can include multiple TCI states, such as 8 TCI states. The multiple TCI states included in the subset of TCI states to be activated usually belong to the TCI states in the 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 the terminal receives the SSB and / or CSI-RS.

[0138] For the TCI state activated by the network device through the MAC-CE, the network device can send the downlink reference signal associated with the TCI state, such as SSB and / or CSI-RS. The downlink reference signal sent by the network device corresponds to a beam, i.e., the network device sends the downlink reference signal through the beam, and the terminal can use different beams to send the downlink reference signal associated with different TCI states.

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

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

[0141] The parameter table includes a plurality of valid time lengths of the QCL. The network device sends the parameter table to the terminal, so that the terminal can determine the valid time length of the QCL of the reference signal corresponding to the optimal candidate beam based on the parameter table.

[0142] Optionally, the parameter table further includes second indication information corresponding to the plurality of valid time lengths of the QCL, that is, the parameter table includes a plurality of corresponding relationships between the second indication information and the valid time lengths of the QCL. For example, the second indication information occupies one or more bits, the value of the one or more bits is 0, and the valid time length of the QCL corresponding to the value is 100 ms. The value of the one or more bits is 1, and the valid time length of the QCL corresponding to the value is 120 ms. Based on this, the terminal can indicate the valid time length of the QCL of the reference signal corresponding to the optimal candidate beam through the second indication information, thereby saving the number of occupied bits of the first message.

[0143] In some embodiments, the parameter table can be included in (i.e., carried by) the RRC signaling, that is, the network device sends the RRC signaling to the terminal, and the RRC signaling includes the parameter table. For example, the RRC signaling carrying the parameter table can be a separate RRC signaling, or the RRC signaling sent by the network device through step S401, that is, the network device sends the RRC signaling to the terminal, and the RRC signaling includes the TCI state pool and the parameter table.

[0144] It can be understood that the network device has the advantage of higher flexibility by 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 state pool to send the parameter table.

[0145] Step S404 is an optional step, and in some embodiments, the network device can not perform step S404.

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

[0147] The terminal performs signal quality measurement (i.e., channel quality measurement) according to the downlink reference signal (e.g., 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 in which the terminal initiates the beam report based on Event-7, the terminal determines whether the quality of a new beam reaches a threshold value according to the L1-RSRP and / or L1-SINR of the beam. In the case where the terminal determines that the quality of at least one new beam reaches the threshold value, the terminal can generate a beam report. The description of the report content of the beam report can be referred to the foregoing content, which will not be described here.

[0149] In the application scenario based on other events or UE-initiated beam measurement, the terminal can also obtain the beam report.

[0150] Optionally, after the terminal performs the signal quality measurement, the terminal can also report a channel state information report configuration (CSI report configuration) to the network device, which can 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] The network device can update the TCI state subset through a MAC CE or downlink control information (DCI) according to the CSI report configuration. The network device can send a downlink reference signal associated with the updated TCI state subset, and the terminal can also perform signal quality measurement according to the downlink reference signal sent by the network device to obtain the L1-RSRP or L1-SINR of the downlink reference signal, and then generate a beam report.

[0152] After the terminal generates the beam report, the terminal can 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, and 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 validity duration of the QCL indicated by the first information. The description of the first message, the first information, and the second information can be referred to the foregoing content, and will not be described here.

[0155] In some embodiments, the terminal can determine the validity duration of the QCL of the reference signal corresponding to the optimal candidate beam by itself.

[0156] For example, the rule for the terminal to determine the validity duration of the QCL of the reference signal corresponding to the optimal candidate beam can be that the validity 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 validity duration determined by the terminal as the validity duration of the QCL of the reference signal corresponding to the optimal candidate beam.

[0157] Optionally, the terminal can determine the effective time length of the QCL of the reference signal corresponding to the optimal candidate beam according to the signal quality of the optimal candidate beam, and the effective time length of the QCL of the reference signal corresponding to the optimal candidate beam determined by the terminal can be taken as the second information and carried in the first message.

[0158] In an implementation manner, the terminal determines the value of the effective time length of the QCL of the reference signal corresponding to the optimal candidate beam according to the signal quality of the optimal candidate beam, and of course, the effective time length 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 manner, the terminal receives a parameter table including multiple effective time lengths of the QCL, and the terminal can determine the effective time length of the QCL positively correlated with the signal quality of the optimal candidate beam from the parameter table according to the signal quality of the optimal candidate beam, as the effective time length of the QCL of the reference signal corresponding to the optimal candidate beam.

[0160] Optionally, the terminal can determine the second indication information according to the signal quality of the optimal candidate beam, and the second indication information indicates the effective time length of the QCL of the reference signal corresponding to the optimal candidate beam. The second indication information can be taken as the second information and carried in the first message.

[0161] In an implementation manner, the parameter table received by the terminal includes multiple corresponding relationships between the effective time length of the QCL and the second indication information, and the terminal can determine the second indication information corresponding to the effective time length of the QCL positively correlated with the signal quality of the optimal candidate beam from the parameter table according to the signal quality of the optimal candidate beam, as the second information.

[0162] In an example, the parameter table includes multiple corresponding relationships between the effective time length of the QCL and the second indication information as follows:

[0163] The second indication information is 0, and the effective time length of the QCL corresponding thereto is 100 ms;

[0164] The second indication information is 1, and the effective time length of the QCL corresponding thereto is 120 ms;

[0165] The second indication information is 2, and the effective time length of the QCL corresponding thereto is 140 ms, and so on.

[0166] Generally, the terminal determines the signal quality of the optimal candidate beam according to step S405, the terminal can select the effective time length of the QCL of the reference signal corresponding to the optimal candidate beam as 100 ms based on the parameter table, and determine the second indication information as 0, and take it as the second information and carry it in the first message.

[0167] In the embodiment of the present application, the terminal determines the effective time length of the QCL of the reference signal corresponding to the optimal candidate beam by itself, 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, the stored QCL of the reference signal corresponding to the optimal candidate beam can be controlled based on the effective time length of the QCL indicated by the second information.

[0169] For example, the terminal sends the first message at a starting time, and starts timing. Within the effective time length of the QCL after the starting time, the terminal continues to store the QCL of the reference signal corresponding to the optimal candidate beam. When the timing time length after the starting time is greater than or equal to a first time length, the terminal can release the QCL of the reference signal corresponding to the optimal candidate beam. The first time length is the effective time length 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, the terminal can determine that no scheduling of the network device is received, that is, no updated TCI state subset sent by the network device is received. It can be understood that the network device can send the updated TCI state subset to the terminal for beam reporting. One TCI state in the updated TCI state subset can be usually associated with the downlink reference signal corresponding to the optimal candidate beam.

[0171] Alternatively, within the effective time length of the QCL after the starting time, the terminal receives the scheduling of the network device, that is, receives the updated TCI state subset sent by the network device. One TCI state in the updated TCI state subset can be usually associated with the downlink reference signal corresponding to the optimal candidate beam. The terminal can 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 can also clear the timing of the timer.

[0172] Figure 5 For example, a flowchart of another reporting method of a beam report provided by the embodiment of the present application is shown.

[0173] As Figure 5 shown, the reporting method of the beam report provided by 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] The RRC signaling includes a TCI state pool.

[0176] The description of the RRC signaling can be referred to the foregoing step S401, which will not be described 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 subset of TCI states to be activated.

[0179] The description of the MAC-CE can refer to the foregoing step S402, and will not be described here again.

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

[0181] The description of the step S503 can refer to the foregoing step S403, and will not be described here again.

[0182] S504, the network device sends a validity duration of a QCL to the terminal, and correspondingly, the terminal receives the validity duration of the QCL.

[0183] The network device can maintain the validity duration of the QCL stored by the terminal, and the network device can configure the validity duration of the QCL to the terminal, so as to control and manage the stored QCL based on the configuration of the network device.

[0184] In some embodiments, the validity duration of the QCL can be included in (i.e., carried by) RRC signaling, that is, the network device sends RRC signaling to the terminal, and the RRC signaling includes the validity duration of the QCL. For example, the RRC signaling carrying the validity duration of the QCL can be a separate RRC signaling, or the network device can send the RRC signaling including the validity duration of the QCL through the step S501, that is, the network device sends RRC signaling to the terminal, and the RRC signaling includes the TCI state pool and the validity duration of the QCL.

[0185] It can be understood that the network device has the advantage of higher flexibility by sending the validity duration of the QCL through a separate RRC signaling, and the network device has the advantage of saving signaling by multiplexing the RRC signaling including the TCI state pool to send the validity duration of the QCL.

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

[0187] The description of the step S505 can refer to the foregoing step S405, and will not be described here again.

[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 the 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 explanations for the first message and the first information can be found in the aforementioned 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 manage the QCL of the reference signal corresponding to the stored optimal candidate beam. The implementation method of the terminal managing the QCL of the reference signal corresponding to the stored optimal candidate beam can be found in the foregoing embodiments, and will not be repeated here.

[0192] The extended storage duration of the QCL can be configured by the network device to the terminal. For example, the network device can configure the extended storage duration of the QCL to the terminal via a second message. The second message may include third information, which is used to indicate the extended storage duration of the QCL indicated by the first information.

[0193] Optionally, the way in which the third information indicates the extended storage duration of the QCL indicated by the first information can be: the third information includes third indication information, which is used to indicate the extended storage duration of the QCL indicated by the first information. Correspondingly, the network device can configure a parameter table for the terminal, and the extended storage duration of the QCL can be determined by the terminal according to the parameter table. For example, the parameter table includes multiple extended storage durations of the QCL and corresponding third indication information.

[0194] Alternatively, the way in which the third information indicates the extended storage duration of the QCL indicated by the first information can also be: the third information includes the extended storage duration of the QCL indicated by the first information.

[0208] The description of the step S604 can refer to the foregoing step S404, and details are not described herein.

[0209] The step S604 is an optional step, and in some embodiments, the network device can not perform the step S604.

[0210] In some embodiments, the network device can further send a second parameter table to the terminal, and the second parameter table can include third indication information corresponding to a plurality of extended storage time lengths of the QCL, that is, the second parameter table includes a plurality of corresponding relationships between the third indication information and the extended storage time lengths of the QCL.

[0211] For example, the third indication information occupies one or more bit positions, the value of the one or more bit positions is 0, and the corresponding extended storage time length of the QCL is 50 ms, the value of the one or more bit positions is 1, and the corresponding extended storage time length of the QCL is 80 ms. Based on this, the network device can indicate the extended storage time length of the QCL of the reference signal corresponding to the most preferred beam through the third indication information, and the number of occupied bit positions of the second message is saved.

[0212] Optionally, the second parameter table can also be the same as the first parameter table, that is, the network device configures one parameter table to the terminal, and the parameter table can include a plurality of valid time lengths of the QCL or a plurality of corresponding relationships between the second indication information and the valid time lengths of the QCL, and can also include a plurality of corresponding relationships between the third indication information and the extended storage time lengths of the QCL.

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

[0214] In some embodiments, the second parameter table can also be included (i.e., carried) in the RRC signaling. For example, the second parameter table and the first parameter table are included in one RRC signaling, or included in different RRC signaling, which can be separate RRC signaling or the RRC signaling sent by the network device through step S601, i.e., the network device sends the RRC signaling to the terminal, and the RRC signaling includes the TCI state pool, the second parameter table and the first parameter table.

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

[0216] The description of step S605 can be referred to the foregoing step S405, which will not be described here.

[0217] S606, the terminal sends a first message to the network device, and correspondingly, the network device receives the first message.

[0218] The first message includes the 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 validity duration of the QCL indicated by the first information.

[0219] After the network device receives the first message, the following three options can be selected:

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

[0221] S607a, the network device sends a TCI update signaling to the terminal, and correspondingly, the terminal receives the TCI update signaling.

[0222] The network device can send the TCI update signaling to the terminal for the beam report, and the terminal receives the TCI update signaling within the validity duration of the QCL after sending the first message. For example, the TCI update signaling includes an updated TCI state subset, and one TCI state in the updated TCI state subset is usually associated with the downlink reference signal corresponding to the optimal candidate beam.

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

[0224] Further optionally, after the terminal receives the TCI update signaling, the terminal can also clear the timing of the timer.

[0225] In some embodiments, the TCI update signaling can be included (i.e., carried) in a MAC-CE, but this does not constitute a limitation.

[0226] At 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 duration of the QCL indicated by the first information.

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

[0229] In an implementation manner, the third information can occupy one or more bit positions, such as 4 bit positions.

[0230] In other embodiments, the second message is a DCI. Optionally, the second message is a DCI 1_0, and the third information can be carried in the DCI 1_0 in a manner of inserting a padding bit. For example: the DCI 1_0 includes a frequency domain resource assignment field, and the third information is located after the frequency domain resource assignment field and occupies one or more bit positions.

[0231] In the second message, the implementation manner of the third information indicating the extended storage duration of the QCL indicated by the first information can be as described above.

[0232] For example, the third information is third indication information, used to indicate the extended storage duration of the QCL indicated by the first information. After receiving the second message, the terminal can determine the extended storage duration of the QCL corresponding to the third indication information in the second message according to a second parameter table, and the terminal can wait for scheduling of the network device within a combined duration (i.e., a second duration) of the valid duration of the QCL after sending the beam report and the extended storage duration.

[0233] For another example, the third information is the extended storage duration of the QCL indicated by the first information. After receiving the second message, the terminal can determine the extended storage duration of the QCL indicated by the first information by using the third information in the second message, and the terminal can wait for scheduling of the network device within a combined duration (i.e., a second duration) of the valid duration of the QCL after sending the beam report and the extended storage duration.

[0234] Optionally, the terminal receives the scheduling of the network device within the second time length, i.e., receives the TCI updating signaling sent by the network device through step S608a, and can receive the downlink reference signal corresponding to the optimal candidate beam using the QCL of the reference signal corresponding to the optimal candidate beam stored.

[0235] Further optionally, the terminal does not receive the scheduling of the network device within the second time length, and can perform the following step S608b when the time length after the sending of the first message is greater than or equal to the second time length.

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

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

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

[0239] The description of the TCI updating signaling can refer to the content of the aforementioned step S607a, which will not be described here again.

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

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

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

[0243] The terminal releases the stored QCL of the reference signal through step S607c when the terminal does not receive the second message sent by the network device within the first time length after sending the first message, and does not receive the scheduling of the network device, which can avoid the problem of invalid occupation of the memory resources of the terminal caused by the stored QCL of the terminal not working and not being released.

[0244] Figure 7 An exemplary flowchart of another beam reporting reporting method provided by the embodiments of the application is shown.

[0245] As shown in Figure 7 , the beam reporting reporting method provided by the embodiments of the application includes:

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

[0247] The RRC signaling includes a TCI state pool.

[0248] The RRC signaling can refer to the foregoing step S401, and details are not described herein.

[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 subset of TCI states to be activated.

[0251] The MAC-CE can refer to the foregoing step S402, and details are not described herein.

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

[0253] The step S703 can refer to the foregoing step S403, and details are not described herein.

[0254] S704, the network device sends an effective duration and an extended storage duration of a QCL to the terminal, and correspondingly, the terminal receives the effective duration and the extended storage duration of the QCL.

[0255] The network device can maintain the effective duration and the extended storage duration of the QCL stored by the terminal. For example, the network device stores a plurality of sets of the effective duration and the extended storage duration of the QCL, and selects one set of the effective duration and the extended storage duration of the QCL to configure the terminal.

[0256] Optionally, the network device stores a range of the effective duration and a range of the extended storage duration of the QCL, for example, the range of the effective duration is 100-200 ms, and the range of the extended storage duration is 0-100 ms. The network device can select one value in the range of the effective duration and one value in the range of the extended storage duration, and configure the terminal.

[0257] The network device can configure the effective duration and the extended storage duration of the QCL to the terminal, so as to control the stored QCL based on the configuration of the network device, and reduce the complexity of the operation of the terminal.

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

[0259] The step S705 can refer to the foregoing step S405, and details are not described herein.

[0260] S706, the terminal sends a first message to the network device, and 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 a QCL of a reference signal in the beam report stored by the terminal.

[0262] The first message and the first information are described above, and details are not described herein.

[0263] After the network device receives the first message through step S706, the network device can send the TCI update signaling within the valid time length of the QCL or can send the TCI update signaling within the extended storage time length after the valid time length of the QCL.

[0264] It can be understood that the network device sends the valid time length of the QCL and the extended storage time length to the terminal through step S704, so that the network device and the terminal synchronize the valid time length of the QCL and the extended storage time length. After the network device receives the first message, the network device can determine whether to schedule according to the beam report of the first message and the scheduling time, that is, whether to send the TCI update instruction and whether to send the TCI update signaling within the valid time length of the QCL or within the extended storage time length after the valid time length of the QCL.

[0265] S707a, the network device sends the TCI update signaling to the terminal within the valid time length of the QCL, and correspondingly, the terminal receives the TCI update signaling.

[0266] The TCI update signaling is described above in step S607a, and details are not described herein.

[0267] S707b, the network device sends the TCI update signaling to the terminal within the extended storage time length of the QCL, and correspondingly, the terminal receives the TCI update signaling.

[0268] The TCI update signaling is described above in step S607a, and details are not described herein.

[0269] S707c, when the timing time length after sending the first message is greater than or equal to a second time length, the terminal releases the stored QCL of the reference signal.

[0270] The second time length is the sum of the valid time length of the QCL and the extended storage time length of the QCL.

[0271] In some embodiments, after the network device receives the first message, the network device can also send one or more second messages to the terminal, and further indicate the extended storage time length of the QCL to the terminal through third information in the second message. Correspondingly, the terminal can receive the second message.

[0272] For example, in a case where the terminal receives the second message after the timing duration after the first message is sent is less than or equal to the valid duration of the QCL, the terminal also 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 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 sent by the network device before.

[0273] Alternatively, the terminal can also continue to store the QCL after the timing duration reaches the valid duration of the QCL until the timing duration reaches the extended storage duration of the QCL sent by the network device through step S704. The terminal can 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. That is, the extended storage duration of the QCL indicated by the third information in the second message is the re-extended storage duration of the QCL stored by the terminal, i.e., 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 the first message is sent is equal to the sum of the valid duration and the extended storage duration of the QCL.

[0274] During the process of storing the QCL based on the extended storage duration of the QCL indicated by the third information, the terminal can wait for the scheduling of the network device, i.e., wait for the TCI update instruction sent by the network device. The implementation manner of the network device sending the TCI update instruction and the action of the terminal after receiving the TCI update instruction can be referred to the foregoing content, which will not be described here.

[0275] After the storage of the QCL based on the extended storage duration of the QCL indicated by the third information expires, the terminal can release the QCL, which can be referred to the foregoing content, which will not be described here.

[0276] For another example, in a case where the terminal receives the second message after 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 sum of the valid duration and the extended storage duration of the QCL, the terminal also continues to store the QCL after the timing duration reaches the sum of the valid duration and the 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, during the process of storing the QCL based on the extended storage duration of the QCL indicated by the third information, the terminal can wait for the scheduling of the network device, i.e., wait for the TCI update instruction sent by the network device. The implementation manner of the network device sending the TCI update instruction and the action of the terminal after receiving the TCI update instruction can be referred to the foregoing content, which will not be described here.

[0278] After the terminal stores the QCL for the extended storage duration indicated by the third information, the terminal can release the QCL after the QCL expires. Details are described above, and will not be described here again.

[0279] Figure 8 is a schematic block diagram of a communication apparatus provided by an embodiment of the present application.

[0280] As shown in Figure 8 , the communication apparatus 800 can include a communication module 820. The communication module 820 can implement a corresponding communication function. The communication function can be an internal communication function of the communication apparatus 800, or a communication function of the communication apparatus 800 and other apparatuses.

[0281] Optionally, the communication apparatus 800 further includes a processing module 810. The processing module 810 can implement a corresponding processing function.

[0282] Optionally, the communication apparatus 800 further includes a storage module. The storage module can be used to store instructions and / or data. The processing module 810 can read the instructions and / or data in the storage module, so that the communication apparatus 800 implements the foregoing method embodiments.

[0283] In a possible design, the communication apparatus 800 can correspond to a terminal in the foregoing method embodiments, or a component (such as a circuit, a chip, or a chip system, etc.) configured in the terminal. The communication apparatus 800 can be used to execute steps or processes performed by the terminal in any of the foregoing method embodiments.

[0284] For example, the communication module 820 is configured to send a first message. The first message includes a beam report, first information, and second information. The first information is used to indicate a QCL of a reference signal in the stored beam report of the terminal. The second information is used to indicate a valid duration of the QCL indicated by the first information. For example, the processing module 810 is configured to release the QCL of the reference signal in the stored beam report in a case that a timing duration after the first message is sent is greater than or equal to a first duration. The first duration is the valid duration of the QCL indicated by the second information. Or the processing module 810 is configured to release the QCL of the reference signal in the stored beam report in a case that the timing duration after the first message is sent is greater than or equal to a second duration. The second duration is a sum of the valid duration of the QCL indicated by the second information and an extended storage duration of the QCL indicated by the first information.

[0285] For example, the communication module 820 is further configured to receive a second message. The second message includes third information. The third information is used to indicate the extended storage duration of the QCL indicated by the first information.

[0286] The above is only an example. Details of the steps or processes can be referred to the descriptions of the foregoing embodiments.

[0287] In one possible design, the communication device 800 may correspond to the network device in the above method embodiments, or to a component (such as a circuit, chip, or chip system) configured in the network device. The communication device 800 can be used to perform the steps or processes performed by the network device in any of the above method embodiments.

[0288] For example, the communication module 820 is used to receive a first message, which includes a beam report, first information, and second information. The first information is used to indicate the quasi-co-address 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 effective 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 effective 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 including third information, the third information being used to indicate an extended storage duration of the QCL indicated by the first information, the extended storage duration of the QCL being used to indicate that if the timing duration after the first message is sent is greater than or equal to a second duration, the stored QCL of the beam report reference signal is released, the second duration being the sum of the effective duration of the QCL indicated by the first information and the extended storage duration of the QCL indicated by the first information.
