[0106] In the present disclosure, "at least one" means one or more, and "more" means 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 mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or plural.

[0107] It is understood that the various steps or operations in the embodiments of the present disclosure are merely examples, and the embodiments of the present disclosure may also perform other operations or variations of various operations. In addition, the various steps may be performed in a different order than those presented in the embodiments of the present disclosure, and it is possible that not all operations in the embodiments of the present disclosure need to be performed.

[0108] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0109] The technical solution provided by the embodiments of the present disclosure can be applicable to a variety of systems, especially 5G and 6G systems. For example, the system to which the embodiments of the present disclosure are applicable can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new radio (NR) system, etc. These various systems all include terminals and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0110] The terminal involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem. In different systems, the name of the terminal may also be different. For example, in a 5G system, the terminal may be called user equipment (UE). A wireless terminal can communicate with one or more core networks (CN) via a radio access network (RAN). A wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal. For example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiated protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. A wireless terminal may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

[0111] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal through one or more sectors on an air interface, or may be called another name. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a network device (NodeB) in wide-band code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the network device may include a central unit (CU) node and a distributed unit (DU) node, and the central unit and the distributed unit may be geographically arranged together or separately.

[0112] In communication systems, low-, mid-, and high-frequency signals can be used for communication. High-frequency signals form beams with a smaller coverage range, requiring beam management (BM) to select appropriate beams for uplink and downlink communications between terminals and network devices.

[0113] In beam management (BM), the network device configures the channel state information (CSI) reporting set (CSI report setting) and resource setting for the terminal. The resource setting is configured with measurement resources: synchronization signal and physical broadcast channel block (SSB), CSI-reference signal (RS). Based on the configuration of the network device, the terminal performs periodic, semi-continuous, and aperiodic resource measurements and reports the measurement results. For periodic and semi-continuous beam measurement reports, the network device configures the period of beam measurement reporting for the terminal; for aperiodic beam measurement reports, the network device triggers the terminal to perform beam measurement reporting and indicates the reporting time to the terminal.

[0114] However, in periodic and semi-continuous beam measurement reporting, if a shorter reporting period is configured, the terminal will perform frequent beam measurement reporting, affecting system performance. If a longer reporting period is configured, the channel state changes on the terminal side cannot be fed back in time. In non-periodic beam measurement reporting, the network equipment cannot grasp the real-time channel state on the terminal side, and the beam measurement report may not be triggered in time, and the channel state changes on the terminal side cannot be reflected in time.

[0115] The present disclosure provides a beam management method, apparatus, and storage medium. When the resource quality of the measurement object of the current beam and / or the resource quality of the measurement object of the candidate beam meet the beam management conditions, the terminal actively reports the beam measurement results, requests beam measurement, and / or requests beam switching to the network device. The network device configures the terminal to perform periodic, semi-continuous, and non-periodic beam measurement reporting, which is beam management triggered by the network device. The present disclosure is terminal-triggered (UE-initiated) beam management. Compared with the network device, the terminal can accurately grasp its own real-time channel status through resource quality measurement. The beam management triggered by the terminal can promptly feedback the terminal's channel status changes to the network device.

[0116] Among them, the resource quality of the measurement object of the current beam and / or the resource quality of the measurement object of the candidate beam meets the beam management conditions, which can be regarded as an event triggering beam management, so the present disclosure can also be understood as event-triggered beam management.

[0117] Among them, the present disclosure can be applied to beam management of a single transmission and receiving point (sTRP) and can also be applied to beam management of multiple transmission and receiving points (mTRP).

[0118] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0119] Based on the above technical concept, the application scenarios of the embodiments of the present disclosure are as follows:

[0120] FIG1 is an example diagram of an application scenario provided by an embodiment of the present disclosure. As shown in FIG1 , the application scenario involved in this embodiment may include a network device 101 and a terminal 102 (there may be multiple terminals 102, and FIG1 takes two terminals as an example), and uplink and downlink communications can be performed between the network device 101 and the terminal 102. The terminal 102 measures the measurement object of the current beam (not shown in the figure) used for uplink and downlink communications and / or measures the measurement object of the candidate beam (not shown in the figure). When the resource quality of the measurement object of the current beam and / or the resource quality of the measurement object of the candidate beam meets the beam management conditions, the terminal 102 reports the beam measurement results, requests beam measurement, and / or requests beam switching to the network device 101, thereby realizing timely feedback of channel state changes on the terminal side.

[0121] The following describes the beam management method, apparatus, and storage medium provided by the embodiments of the present disclosure in conjunction with the application scenario of Figure 1 and with reference to Figures 2 to 5. It should be noted that the above application scenarios are merely provided to facilitate understanding of the spirit and principles of the present disclosure, and the embodiments of the present disclosure can be applied to any applicable scenario.

[0122] FIG2 is a flow chart of a beam management method according to an embodiment of the present disclosure. As shown in FIG2 , the beam management method according to this embodiment may include:

[0123] S201, the terminal measures the first measurement object and / or the second measurement object to obtain the resource quality of the first measurement object and / or the resource quality of the second measurement object, where the first measurement object is the measurement object corresponding to the current beam, and the second measurement object is the measurement object corresponding to the candidate beam.

[0124] The measurement object refers to the resource object to be measured, which can be a single resource to be measured, such as SSB, CSI-RS, or a resource set consisting of multiple resources to be measured.

[0125] The resource quality of the measurement object may include reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), and signal to interference plus noise ratio (SINR), such as the absolute value or differential value of RSRP.

[0126] Among them, the current beam is the beam currently used by the terminal and the network device for uplink and downlink communications, and the candidate beam is the beam available for the terminal to select in beam management. The network device can pre-configure one or more candidate beams for the terminal.

[0127] In this embodiment, the terminal may measure the first measurement object and / or the second measurement object in real time, at regular intervals, or when detecting that its own signal is poor, to obtain the resource quality of the first measurement object and / or the resource quality of the second measurement object. The resource quality of the first measurement object reflects the beam quality of the current beam; the higher the resource quality of the first measurement object, the higher the beam quality of the current beam; the resource quality of the second measurement object reflects the beam quality of the candidate beam; the higher the resource quality of the second measurement object, the higher the beam quality of the candidate beam.

[0128] S202: If the resource quality of the first measurement object and / or the resource quality of the second measurement object meets the beam management conditions, the terminal sends first information to the network device, and the first information is used for one or more of the following: reporting beam measurement results, requesting beam measurement, and requesting beam switching.

[0129] The beam management condition is a configured condition for triggering beam management. The resource quality of the first measurement object and / or the resource quality of the second measurement object meeting the beam management condition can indicate one or more of the following situations: poor beam quality of the current beam, good beam quality of the candidate beam, or better beam quality of the candidate beam than the current beam. If any of these situations occurs, the terminal can proactively trigger beam management to provide timely feedback on changes in its channel state.

[0130] In this embodiment, the terminal may measure the resource quality of the first measurement object and send first information if the resource quality of the first measurement object meets the beam management condition; alternatively, the terminal may measure the resource quality of the second measurement object and send first information if the resource quality of the second measurement object meets the beam management condition; alternatively, the terminal may measure the resource quality of the first measurement object and the resource quality of the second measurement object and send first information if the resource quality of the first measurement object and / or the resource quality of the second measurement object meet the beam management condition. The first information may be used to report beam measurement results, such as reporting the resource quality of the first measurement object and / or the resource quality of the second measurement object; the first information may be used to request beam measurement, i.e., requesting the network device to instruct the terminal to perform beam measurement, which is equivalent to the terminal itself notifying the network device to instruct the terminal to perform beam measurement in a timely manner after discovering a change in the channel state; the first information may be used to request beam switching, such as when the resource quality of the second measurement object is good, the terminal may request the network device to instruct the terminal to switch to a candidate beam through the first information. Reporting beam measurement results, requesting beam measurement, and requesting beam switching are all beam management operations. The terminal can actively trigger one or more of them, such as requesting beam measurement while reporting beam measurement results.

[0131] In an embodiment of the present disclosure, when the resource quality of the measurement object corresponding to the current beam and / or the resource quality of the measurement object corresponding to the candidate beam meets the beam management conditions, the terminal actively initiates beam management to the network device, including actively reporting beam measurement results, requesting beam measurement and / or requesting beam switching, so that the network device can promptly grasp the channel state changes on the terminal side, and promptly improve the communication quality between the network device and the terminal through beam management operations such as beam measurement and beam switching.

[0132] For the beam management triggered by the terminal, which measurement objects are measured (that is, which resources or resource sets can be the first measurement object and the second measurement object), which uplink channel resources the terminal uses to send the first information, and what the content of the first information can include are issues further addressed by the present disclosure.

[0133] Below, corresponding embodiments are provided for the measurement object.

[0134] In some embodiments, the first measurement object and / or the second measurement object are configured measurement objects and / or rule-defined measurement objects. The first measurement object and / or the second measurement object may be configured by a network device for the terminal, or may be provided in a communication rule.

[0135] The configured measurement object may be a configured resource or resource set; the rule-defined measurement object may be a rule-defined resource or resource set.

[0136] In this embodiment, the first measurement object and / or the second measurement object are configured measurement objects and / or rule-defined measurement objects, which may include the following situations: the first measurement object and the second measurement object are both configured measurement objects, the first measurement object and the second measurement object are both rule-defined measurement objects, the first measurement object is a configured measurement object and the second measurement object is a rule-defined measurement object, and the first measurement object is a rule-defined measurement object and the second measurement object is a configured measurement object.

[0137] In one implementation, the configured measurement objects include: a CSI-RS resource set associated with a CSI reporting configuration, and / or a CSI-RS resource associated with a CSI reporting configuration. One or more of the CSI reporting configuration, the CSI-RS resource set, and the CSI-RS resource are configured for the terminal by a network device.

[0138] A CSI-RS resource set includes one or more CSI-RS resources. A CSI-RS resource is a CSI-RS. A CSI-RS resource set can be understood as a signal set consisting of one or more CSI-RSs. A CSI reporting configuration can be associated with one or more CSI-RS resource sets and one or more CSI-RS resources.

[0139] The CSI reporting configuration may be a CSI-reportConfig configured by a network device for a terminal under a traditional CSI reporting framework. The CSI-reportConfig is associated with a CSI resource setting. The CSI resource setting includes one or more CSI resource sets, and the CSI resource set includes one or more CSI-RS resources. In the configured measurement object, the CSI-RS resource set may be a CSI resource setting or a CSI resource set, and the CSI-RS resource may be a CSI-RS resource.

[0140] In this implementation, the first measurement object and the second measurement object are different CSI-RS resource sets associated with the CSI reporting configuration, or the first measurement object and the second measurement object are different CSI-RS resources associated with the CSI reporting configuration, or the first measurement object is a CSI-RS resource set associated with the CSI and the second measurement object is a CSI-RS resource associated with the CSI reporting configuration, or the first measurement object is a CSI-RS resource set associated with the CSI and the second measurement object is a CSI-RS resource associated with the CSI reporting configuration.

[0141] In one implementation, the CSI reporting configuration is associated with at least two CSI-RS resource sets, the first measurement object is the first CSI-RS resource set in the at least two CSI-RS resource sets, the second measurement object is the second CSI-RS resource set in the at least two CSI-RS resource sets, and the first CSI-RS resource set and the second CSI-RS resource set are different CSI-RS resource sets.

[0142] The CSI reporting configuration is associated with at least two CSI-RS resource sets, which may mean that the CSI reporting configuration includes or corresponds to at least two CSI-RS resource sets.

[0143] In this implementation, of the at least two CSI-RS resource sets associated with the CSI reporting configuration, the first CSI-RS resource set is used for quality measurement of the current beam, and the second CSI-RS resource set is used for quality measurement of candidate beams. Thus, by configuring different CSI-RS resource sets for the current beam and candidate beams as measurement targets, the accuracy of beam quality measurement for the current beam and candidate beams is improved.

[0144] FIG3 is a second flow chart of the beam management method provided by an embodiment of the present disclosure. As shown in FIG3 , the beam management method of this embodiment may include:

[0145] S301: The terminal reports the beam management capability that supports terminal triggering to the network device.

[0146] Among them, S301 is an optional step.

[0147] In this embodiment, the terminal reports to the network device that it supports (or possesses) terminal-triggered (or event-triggered) beam management capabilities, so that the network device configures configuration information for terminal-triggered beam management for the terminal based on the beam management capabilities of the terminal.

[0148] S302, the network device indicates the CSI reporting configuration to the terminal, and the CSI reporting configuration is associated with the first CSI-RS resource set and the second CSI-RS resource set. The first CSI-RS resource set is the measurement object corresponding to the current beam, and the second CSI-RS resource set is the measurement object corresponding to the candidate beam.

[0149] The first CSI-RS resource set can also be referred to as the current beam measurement resource set, and the second CSI-RS resource set can also be referred to as the candidate beam measurement resource set. The first CSI-RS resource set is the measurement object corresponding to the current beam, i.e., the first measurement object, and the second CSI-RS resource set is the measurement object corresponding to the candidate beam, i.e., the second measurement object. The first measurement object, the second measurement object, the first CSI-RS resource set, and the second CSI-RS resource set can be referred to in the above description and will not be repeated here.

[0150] The first CSI-RS resource set and the second CSI-RS resource set may each include one or more CSI-RS resources. For example, the first CSI-RS resource set is {CSI-RS1, CSI-RS3, CSI-RS5}, and the second CSI-RS resource set is {CSI-RS2, CSI-RS4, CSI-RS6}.

[0151] In this embodiment, the network device can indicate the CSI reporting configuration to the terminal through control plane signaling or user plane data, such as radio resource control (RRC) signaling, to provide the terminal with the configuration information required for beam management.

[0152] S303: The terminal measures the CSI-RS resources in the first CSI-RS resource set to obtain resource quality of the CSI-RS resources in the first CSI-RS resource set.

[0153] In this embodiment, the first CSI-RS resource set may include one or more CSI-RS resources. The terminal may measure each CSI-RS resource in the first CSI-RS resource set to obtain the resource quality of each CSI-RS resource in the first CSI-RS resource set.

[0154] S304: The terminal measures the CSI-RS resources in the second CSI-RS resource set to obtain resource quality of the CSI-RS resources in the second CSI-RS resource set.

[0155] In this embodiment, the second CSI-RS resource set may include one or more CSI-RS resources. The terminal may measure each CSI-RS resource in the second CSI-RS resource set to obtain the resource quality of each CSI-RS resource in the second CSI-RS resource set.

[0156] In some embodiments, the terminal may measure the CSI-RS resources in the first CSI-RS resource set and the CSI-RS resources in the second CSI-RS resource set according to the quality type configured by the network device. For example, if the quality type configured by the network device is RSRP, the terminal may measure the RSRP of the CSI-RS resources in the first CSI-RS resource set and the RSRP of the CSI-RS resources in the second CSI-RS resource set. For example, when the first CSI-RS resource set is {CSI-RS1, CSI-RS3, CSI-RS5} and the second CSI-RS resource set is {CSI-RS2, CSI-RS4, CSI-RS6}, the RSRP1 of CSI-RS1, RSRP3 of CSI-RS3, RSRP5 of CSI-RS5, RSRP2 of CSI-RS2, RSRP4 of CSI-RS4, and RSRP6 of CSI-RS6 may be measured.

[0157] S305. If one or more of the resource quality of the CSI-RS resources in the first CSI-RS resource set, the resource quality of the CSI-RS in the second CSI-RS resource set, and the quality difference between the resource quality of the CSI-RS resources in the first CSI-RS resource set and the resource quality of the CSI-RS resources in the second CSI-RS resource set meets the beam management conditions, the terminal sends first information to the network device, and the first information is used for one or more of the following: reporting beam measurement results, requesting beam measurement, and requesting beam switching.

[0158] Among them, the resource quality of the CSI-RS resources in the first CSI-RS resource set is the resource quality of the first measurement object. It can be understood that the resource quality of the first measurement object may include the resource quality of each CSI-RS resource in the first CSI-RS resource set; the resource quality of the CSI-RS resources in the second CSI-RS resource set is the resource quality of the second measurement object. It can be understood that the resource quality of the second measurement object may include the resource quality of each CSI-RS resource in the second CSI-RS resource set.

[0159] The resource quality of the first measurement object and / or the resource quality of the second measurement object meets the beam management condition, which may include one or more of the following: the resource quality of the CSI-RS resources in the first CSI-RS resource set meets the beam management condition; the resource quality of the CSI-RS resources in the second CSI-RS resource set meets the beam management condition; the quality difference between the resource quality of the CSI-RS resources in the first CSI-RS resource set and the resource quality of the CSI-RS resources in the second CSI-RS resource set meets the beam management condition.

[0160] Among them, the resource quality of the CSI-RS resources in the first CSI-RS resource set meets the beam management conditions, for example: the resource quality of all CSI-RS resources in the first CSI-RS resource set is less than the first threshold, the resource quality of the best quality CSI-RS resource in the first CSI-RS resource set is less than the first threshold, and the average resource quality of all CSI-RS resources in the first CSI-RS resource set is less than the first threshold.

[0161] Among them, the resource quality of the CSI-RS resources in the second CSI-RS resource set meets the beam management conditions, for example: the resource quality of all CSI-RS resources in the second CSI-RS resource set is greater than the second threshold, the resource quality of the best CSI-RS resource in the second CSI-RS resource set is greater than the second threshold, and the average resource quality of all CSI-RS resources in the second CSI-RS resource set is greater than the second threshold.

[0162] Among them, the quality difference between the resource quality of the CSI-RS resources in the first CSI-RS resource set and the resource quality of the CSI-RS resources in the second CSI-RS resource set meets the beam management condition, for example: the quality difference obtained by subtracting the resource quality of the best CSI-RS resource in the first CSI-RS resource set from the resource quality of the best CSI-RS resource in the second CSI-RS resource set is greater than the third threshold, and the quality difference obtained by subtracting the average resource quality of the CSI-RS resources in the second CSI-RS resource set from the average resource quality of the CSI-RS resources in the first CSI-RS resource set is greater than the third threshold.

[0163] Among them, the first threshold, the second threshold, and the third threshold are configured thresholds.

[0164] In this embodiment, if one or more of the resource quality of the CSI-RS resources in the first CSI-RS resource set, the resource quality of the CSI-RS in the second CSI-RS resource set, and the quality difference between the resource quality of the CSI-RS resources in the first CSI-RS resource set and the resource quality of the CSI-RS resources in the second CSI-RS resource set meet the beam management conditions, it indicates at least one of the following situations: the beam quality of the current beam is poor, the beam quality of the candidate beam is good, and the beam quality of the candidate beam is better than the beam quality of the current beam. In order to improve the communication quality, the terminal sends a first information to the network device to actively report the beam measurement results, request beam measurement and / or request beam switching to the network device.

[0165] As an example, the first CSI-RS resource set is {CSI-RS1, CSI-RS3, CSI-RS5}, and the second CSI-RS resource set is {CSI-RS2, CSI-RS4, CSI-RS6}. The terminal measures and sorts the CSI-RS resources in the first CSI-RS resource set, and obtains that the RSRP1 of CSI-RS1 is the largest. The terminal measures and sorts the resources in the second CSI-RS resource set, and obtains that the RSRP2 of CSI-RS2 is the largest. The terminal compares RSRP1 and RSRP2 and finds that RSRP1 is much larger than RSRP2, indicating that the beam quality of the candidate beam is much better than the beam quality of the current beam, and sends the first information to the network device.

[0166] In an embodiment of the present disclosure, beam management triggered by a terminal is provided when the first measurement object is the first CSI-RS resource set and the second measurement object is the second CSI-RS resource set: the terminal can measure the CSI-RS resources in the first CSI-RS resource set and the CSI-RS resources in the second CSI-RS resource set respectively; if one or more of the resource quality of the CSI-RS resources in the first CSI-RS resource set, the resource quality of the CSI-RS in the second CSI-RS resource set, and the quality difference between the resource quality of the CSI-RS resources in the first CSI-RS resource set and the resource quality of the CSI-RS resources in the second CSI-RS resource set meet the beam management conditions, first information is sent to the network device. In this way, beam management triggered by the terminal is implemented, and channel state changes on the terminal side are fed back to the network device in a timely manner.

[0167] When the first measurement object is a CSI-RS resource set or CSI-RS resource associated with the CSI reporting configuration, in one implementation, the first measurement object may correspond to the same quasi co-location list (qcl-info) as the transmission configuration indicator (TCI) state (TCI state) currently indicated by the terminal. Quasi co-location (QCL) means that signals sent by two antenna ports experience a wireless channel with common characteristics, and the first measurement object corresponds to the same quasi co-location list as the TCI state currently indicated by the terminal, indicating that the first measurement object and the source reference signal in the TCI state currently indicated by the terminal have the same beam direction, and the beam corresponding to the source reference signal in the TCI state currently indicated by the terminal is the current beam of the terminal. Therefore, the first measurement object corresponds to the same quasi co-location list as the TCI state currently indicated by the terminal, so that the resource quality of the measured first measurement object can accurately reflect the beam quality of the current beam.

[0168] Among them, the TCI state includes the source reference signal and the quasi-co-location type (QCL Type) corresponding to the source reference signal, such as QCL Type D corresponding to Source RS1 and Source RS1, and QCL Type X corresponding to Source RS2 and Source RS2. The network device can configure multiple TCI states for the terminal and activate one or more of the multiple TCI states. The terminal can use the beam corresponding to the source reference signal in one of the TCI states (i.e., the current beam) for uplink and downlink communication in the activated TCI state. The adopted TCI state is the TCI state currently indicated by the terminal.

[0169] FIG4 is a flow chart of the beam management method according to an embodiment of the present disclosure. As shown in FIG4 , the beam management method according to this embodiment may include:

[0170] S401: The terminal reports the beam management capability supporting terminal triggering to the network device.

[0171] Among them, S401 is an optional step.

[0172] The implementation principle and technical effects of S401 may refer to the aforementioned embodiments and will not be described in detail.

[0173] S402: The network device indicates a CSI reporting configuration to the terminal, where the first measurement object is a CSI-RS resource associated with the CSI reporting configuration and a quasi-co-location list corresponding to the same TCI state currently indicated by the terminal.

[0174] In this embodiment, the network device may indicate the CSI reporting configuration to the terminal through control plane signaling or user plane data, such as through RRC signaling, and may also indicate that the first measurement object (i.e., the measurement object corresponding to the current beam) is a CSI-RS resource associated with the CSI reporting configuration and that the first measurement object corresponds to the same quasi-co-location list as the TCI state currently indicated by the terminal. For example, the first measurement object is indicated as CSI-RS1 in the CSI reporting configuration, and CSI-RS1 corresponds to the same quasi-co-location list as the TCI state currently indicated by the terminal (e.g., TCI-state#1).

[0175] S403: The network device configures N TCI states for the terminal and activates M TCI states among the N TCI states, where N is greater than M, and N and M are positive integers.

[0176] Among them, S403 to S405 can be performed before S402 or after S402.

[0177] In this embodiment, the network device configures N TCI states for the terminal, for example, 128 TCI states, and can activate M TCI states among the N TCI states through a medium access control (MAC) control element (CE), for example, activating 3 TCI states among the 128 TCI states: TCI state1, TCI state3, and TCI state5.

[0178] S404: The network device instructs the terminal that uplink / downlink communication between the network device and the terminal adopts a target TCI state among the M TCI states.

[0179] S405, on the terminal side, target TCI status indication.

[0180] In this embodiment, the network device indicates to the terminal that uplink / downlink communication between the network device and the terminal adopts a target TCI state among M TCI states, so that the target TCI state is indicated at the terminal.

[0181] In some embodiments, the network device may indicate a target TCI state, such as TCI state 1, to the terminal in the nth time slot, indicating that uplink / downlink communications between the network device and the terminal after the nth time slot use the beam corresponding to the source reference signal in the target TCI state. In the n+kth time slot, the target TCI state is indicated on the terminal side, where k is greater than 0. After the target TCI state is indicated on the terminal side, the first measurement object is the CSI-RS resources associated with the CSI reporting configuration and the quasi-co-location list corresponding to the same target TCI state.

[0182] S406: The terminal measures the first measurement object to obtain resource quality of the first measurement object.

[0183] In this embodiment, the terminal may measure the first measurement object according to the quality type configured by the network device to obtain the resource quality of the first measurement object.

[0184] As an example, the quality type configured by the network device is RSRP, the first measurement object is CSI-RS1, and the terminal can measure CSI-RS1 to obtain RSRP1 of the CSI-RS.

[0185] S407: If the resource quality of the first measurement object meets the beam management condition, the terminal sends first information to the network device, where the first information is used for one or more of the following: reporting beam measurement results, requesting beam measurement, and requesting beam switching.

[0186] The resource quality of the first measurement object meeting the beam management condition may include that the resource quality of the first measurement object is less than a first threshold, and the first threshold is a configured threshold.

[0187] In this embodiment, if the resource quality of the first measurement object is less than the first threshold, it means that the beam quality of the current beam is poor. In order to improve the communication quality, the terminal sends a first information to the network device to actively report the beam measurement results to the network device, request beam measurement and / or request beam switching.

[0188] As an example, the quality type configured by the network device is RSRP, the first measurement object is CSI-RS1, and the resource quality of the first measurement object is RSRP1 of CSI-RS. The terminal compares RSRP1 with the threshold threshold1 and finds that RSRP1 is much smaller than threshold1, then sends the first information to the network device to actively report the beam measurement result, request beam measurement and / or request beam switching.

[0189] In an embodiment of the present disclosure, terminal-triggered beam management is provided when the first measurement object is a CSI-RS resource associated with a CSI reporting configuration and corresponds to the same quasi-co-location list as the TCI state currently indicated by the terminal. A network device can configure CSI reporting and TCI state for the terminal device, and the terminal measures the first measurement object. If the resource quality of the first measurement object meets the beam management condition, it indicates that the beam quality of the current beam is poor, and first information is sent to the network device. In this way, terminal-triggered beam management is implemented, and timely feedback of channel state changes on the terminal side is provided to the network device.

[0190] In some embodiments, the measurement objects defined by the rules include: a quasi-co-location type QCL-TypeD source reference signal contained in the TCI state indicated by the network device within the target time window; and / or a source reference signal contained in the TCI state currently indicated by the terminal.

[0191] The target time window is the time window configured by the network device to the terminal. The TCI state indicated by the network device within the target time window may be the TCI state configured for the terminal or the activated TCI state indicated to the terminal. The beam corresponding to the QCL-TypeD source reference signal in the TCI state indicated by the network device within the target time window is a candidate beam for the terminal; the beam corresponding to the source reference signal in the TCI state currently indicated by the terminal is the current beam for the terminal. Therefore, when the first measurement object and / or the second measurement object are measurement objects defined by a rule, the second measurement object may be the QCL-TypeD source reference signal included in the TCI state indicated by the network device within the target time window, and the first measurement object may be the source reference signal included in the TCI state currently indicated by the terminal.

[0192] QCL-Type D is one of several quasi-co-location types, including QCL-Type A, QCL-Type B, QCL-Type C, and QCL-Type D. Different quasi-co-location types correspond to different large-scale parameters. The large-scale parameter corresponding to QCL-Type D is the spatial receiver parameter (Spatial Rx parameter), which reflects the beamforming characteristics of the downlink receive signal. Therefore, using the QCL-Type D source reference signal as the measurement object ensures that the resource quality of the measurement object accurately reflects the corresponding beam quality, improving the accuracy of beam management.

[0193] Below, corresponding embodiments are provided for channel resources used to transmit the first information.

[0194] In some embodiments, the channel resources used to send the first information may include one or more of the following: channel resources configured through CSI reporting configuration; channel resources obtained through resource scheduling (SR) request; physical random access channel (PRACH) resources configured for the first information; pre-configured physical uplink shared control channel (PUSCH) resources; and pre-configured physical uplink control channel (PUCCH) resources. Thus, one or more channel resources are provided for sending the first information to ensure accurate transmission of the first information.

[0195] Among them, the channel resources configured through the CSI reporting configuration refer to the channel resources included in the CSI reporting configuration. The CSI reporting configuration is configured by the network device for the terminal. For details, please refer to the aforementioned embodiment and will not be repeated here. The channel resources obtained through the SR request are the channel resources allocated to the terminal by the network device in response to the SR request after the terminal sends an SR request to the network device; the PRACH resources configured for the first information are pre-configured by the network device for the first information. The network device can configure one or more PRACH resources for the first information. If the network device configures multiple PRACH resources for the first information, the terminal device can select the PRACH resource for sending the first information from the multiple PRACH resources according to the resource availability; the pre-configured PUSCH resources can be pre-configured by the network device; the pre-configured PUCCH resources can be pre-configured by the network device.

[0196] In this embodiment, if the resource quality of the first measurement object and / or the resource quality of the second measurement object meets the beam management conditions, the terminal may send the first information to the network device on one or more channel resources including the channel resources configured through CSI reporting configuration, the channel resources obtained through SR request, the PRACH resources configured for the first information, and the pre-configured PUCSH resources.

[0197] When the channel resources used to send the first information are channel resources configured via the CSI reporting configuration, the channel resources used to send the first information are further determined on demand from the channel resources configured via the CSI reporting configuration. The CSI reporting configuration may include multiple channel resources, and the terminal may select a channel resource from these multiple channel resources for sending the first information based on actual needs. This conserves channel resources in the CSI reporting configuration, and resource locations not used for sending the first information can be used to transmit other information, thereby improving resource utilization.

[0198] When the channel resources used to send the first information are channel resources configured through CSI reporting configuration, in one implementation, the channel resources used to send the first information include one or more of the following: periodic physical uplink control channel (PUCCH) resources, semi-persistent PUCCH resources, and semi-persistent PUSCH resources. That is, the channel resources included in the CSI reporting configuration may be periodic PUCCH resources, semi-persistent PUCCH resources, or semi-persistent PUSCH resources, and the terminal may send the first information on the periodic PUCCH resources, semi-persistent PUCCH resources, or semi-persistent PUSCH resources included in the CSI reporting configuration. Thus, periodic or semi-persistent beam management triggered by the terminal may be implemented.

[0199] In this implementation, the terminal can receive the CSI reporting configuration sent by the network device. The CSI reporting configuration may include information for configuring periodic PUCCH resources, semi-persistent PUCCH resources and / or semi-persistent PUSCH resources, and may also include information for instructing the terminal to report CSI.

[0200] In the case where the channel resources used to send the first information include one or more of periodic PUCCH resources, semi-persistent PUCCH resources, and semi-persistent PUSCH resources, in one implementation, the terminal may send the first information on part of the transmission timing of the periodic PUCCH resources; or, after receiving the second information, send the first information on part of the transmission timing of the semi-persistent PUCCH resources or part of the transmission timing of the semi-persistent PUSCH resources, where the second information is used to indicate the activation of the CSI reporting corresponding to the CSI reporting configuration.

[0201] In this implementation, if the resource quality of the first measurement object and / or the resource quality of the second measurement object meets the beam management conditions, the terminal may send first information to the network device at part of the transmission timing of the periodic PUCCH resources, and after the next measurement, the first information may also be sent at part of the transmission timing of the periodic PUCCH resources to realize periodic beam management triggered by the terminal; or, the network device may send second information to the terminal, and activate the CSI reporting corresponding to the CSI reporting configuration through the second information. After receiving the second information, the terminal may send first information to the network device at part of the transmission timing of the semi-continuous PUCCH resources or part of the transmission timing of the semi-continuous PUSCH resources to realize semi-continuous beam management triggered by the terminal.

[0202] When the channel resources used to send the first information include channel resources obtained through an SR request, in one implementation, before sending the first information, the terminal may send third information to the network device, the third information being used to request an SR; after sending the third information, the terminal may receive fourth information from the network device, the fourth information indicating the channel resources used to send the first information. Thus, corresponding channel resources are allocated to the first information through the SR.

[0203] In the case of a physical random access channel (PRACH) resource configured for the first information, in one implementation, the network device may configure a set of preamble sequences and random access occasion (RACH occasion, RO) sequences corresponding to the preamble sequences to the terminal, wherein the preamble in the preamble sequence corresponds one-to-one to the RO in the RO sequence; the terminal may select a target RO in the RO sequence, and send the preamble corresponding to the target RO on the time-frequency resources corresponding to the target RO, and the transmission beam of the preamble corresponding to the target RO may be the receiving beam corresponding to the second measurement object, to indicate that the recommended switching beam is the receiving beam corresponding to the second measurement object.

[0204] As an example, the network device configures the preamble code sequence for the terminal: {preamble1, preamble2, preamble3, preamble4} and the RO sequence corresponding to the preamble code sequence: {RO1, RO2, RO3, RO4}, the first measurement object is the CSI-RS resource: CSI-RS1, and the second measurement object is the CSI-RS resource set: {CSI-RS2, CSI-RS3}; the terminal measures CSI-RS1 to obtain the resource quality RSRP1 of CSI-RS1, and measures {CSI-RS2, CSI-RS3} to obtain the resource quality RSRP2 of CSI-RS2 and the resource quality RSRP3 of CSI-RS3, and finds that RSRP3 is much larger than RSRP2, and RSRP1 is less than RSRP3 in multiple consecutive time slots. The terminal can send preamble1 on the time-frequency resource corresponding to RO1, the transmit beam of preamble1 and the receive beam of CSI-RS3, so as to inform the network device that the beam recommended for switching by the terminal after measurement is the beam corresponding to CSI-RS3.

[0205] Below, corresponding embodiments are provided for the content of the first information.

[0206] In some embodiments, the first information includes one or more of the following: a reporting type included in the CSI reporting configuration, the reporting type is used to indicate one or more of the following: whether the CSI reporting configuration is used for or not used for CSI reporting for beam management initiated by the terminal, whether the first information belongs to or does not belong to CSI reporting for beam management initiated by the terminal, and time resource information associated with the first information; resource quality of the first measurement object; resource quality of the second measurement object; the difference between the resource quality of the first measurement object and the resource quality of the second measurement object; the beam identifier of the current beam; the beam identifier of the candidate beam, at least one beam among the candidate beams meets the triggering condition; a downlink beam management request, wherein the downlink beam management request includes a downlink beam measurement request or a downlink beam switching request; a reference signal (BF-RS) for beam failure (BF) measurement; request information for requesting the network device to allocate uplink resources; and indication information for instructing the network device to report beam quality.

[0207] The first information includes a reporting type, so that the network device can determine, based on the reporting type, whether the CSI reporting configuration based on which the terminal's current report is based is used for CSI reporting for beam management initiated by the terminal, whether the first information reported by the terminal this time belongs to CSI reporting for beam management initiated by the terminal, and can also determine time resource information associated with the first information. The time resource information can be the time slot between the reporting type and the remaining content of the first information other than the reporting type, for example, the resource quality of the first measurement object reported by the terminal after one or more consecutive time slots.

[0208] In some embodiments, the reporting type may be represented by a beam quality indicator (BQI) whose data type is a bit type.

[0209] The resource quality of the first measurement object, the resource quality of the second measurement object, and the difference between the resource quality of the first measurement object and the resource quality of the second measurement object can be referred to the description of the aforementioned embodiment and will not be repeated here. The first information includes the resource quality of the first measurement object, the resource quality of the second measurement object, and the difference between the resource quality of the first measurement object and the resource quality of the second measurement object, which can facilitate the network device to understand the beam quality of the current beam and the beam quality of the candidate beam, and then make instructions such as whether to perform beam measurement and beam switching, thereby improving the accuracy of beam management.

[0210] The beam identifier of the current beam uniquely identifies the current beam, allowing network equipment to determine the terminal's current beam. The beam identifier of the candidate beam uniquely identifies the candidate beam, allowing network equipment to determine the recommended beam after the terminal performs beam measurement. At least one of the candidate beams meets the trigger condition. It should be noted that at least one of the candidate beams meeting the trigger condition means that the quality or performance indicators of at least one of the candidate beams meet preset standards. Trigger conditions include, but are not limited to, signal strength, signal quality, bit error rate, and stability.

[0211] Among them, the first information may include a downlink beam management request. When the downlink beam management request includes a downlink beam measurement request, the terminal requests the network device to instruct to perform downlink beam measurement, and the network device triggers the downlink beam measurement to improve the downlink beam quality; when the downlink beam management request includes a downlink beam switching request, the terminal requests the network device to instruct to switch to a better downlink beam based on the beam measurement result reported by the terminal to improve the downlink beam quality.

[0212] Among them, the reference signal used for beam failure measurement can be the reference signal corresponding to the current beam. For example, when the resource quality of the first measurement object is poor, the terminal can report the reference signal used for beam failure measurement so that the network device can measure whether the current beam is failed based on the reference signal.

[0213] In one implementation, if the resource quality of the first measurement object is less than a first threshold, the first information may include one or more of the following: a reporting type, a downlink beam management request, a beam identifier of the current beam, the resource quality of the first measurement object, and a reference signal for beam failure measurement. Therefore, when only the first measurement object is measured, the first information may selectively include one or more of the reporting type, the downlink beam management request, the beam identifier of the current beam, the resource quality of the first measurement object, and a reference signal for beam failure measurement.

[0214] In yet another implementation, if the resource quality of the second measurement object is greater than the second threshold, the first information may include one or more of the following: a reporting type, a downlink beam management request, a beam identifier of a candidate beam, the resource quality of the second measurement object, and a reference signal for beam failure measurement. Thus, when only the second measurement object is measured, the first information may selectively include one or more of the reporting type, the downlink beam management request, the beam identifier of a candidate beam, the resource quality of the second measurement object, and a reference signal for beam failure measurement.

[0215] In another implementation, if the difference between the resource quality of the second measurement object and the resource quality of the first measurement object is greater than a third threshold value, the first information may include one or more of the following: reporting type, beam identifier of the candidate beam, resource quality of the first measurement object, beam identifier of the current beam, resource quality of the second measurement object, and reference signal for beam failure measurement. Thus, when measuring the first measurement object and the second measurement object, the first information may selectively include one or more of the reporting type, beam identifier of the candidate beam, resource quality of the first measurement object, beam identifier of the current beam, resource quality of the second measurement object, and reference signal for beam failure measurement. In particular, it may include the beam identifier of the candidate beam, resource quality of the first measurement object, beam identifier of the current beam, and resource quality of the second measurement object, so that the network device can determine the quality difference between the candidate beam and the current beam based on this information.

[0216] The first information may include request information for requesting the network device to allocate uplink resources. In some embodiments, the request information for requesting the network device to allocate uplink resources may be a Scheduling Request (SR). By sending this request information to the network device, uplink resource allocation may be requested for data transmission.

[0217] The first information may include instruction information for instructing the network device to report beam quality. In some embodiments, beam quality reporting typically involves "beam reporting" or CSI feedback. By instructing the network device to report beam quality, the current channel conditions can be promptly understood to optimize beamforming and resource allocation, thereby improving communication efficiency and reliability.

[0218] FIG5 is a flow chart of the third embodiment of the beam management method provided by the present disclosure. As shown in FIG4 , the beam management method of this embodiment may include:

[0219] S501, the terminal measures the first measurement object and / or the second measurement object to obtain the resource quality of the first measurement object and / or the resource quality of the second measurement object, where the first measurement object is the measurement object corresponding to the current beam, and the second measurement object is the measurement object corresponding to the candidate beam.

[0220] S502: If the resource quality of the first measurement object and / or the resource quality of the second measurement object meets the beam management conditions, the terminal sends first information to the network device, and the first information is used for one or more of the following: reporting beam measurement results, requesting beam measurement, and requesting beam switching.

[0221] The implementation principles and technical effects of S501 to S502 may refer to the aforementioned embodiments and will not be described in detail.

[0222] S503: The network device sends fifth information to the terminal, where the fifth information indicates switching to the candidate beam, or the fifth information is used for configuring downlink beam management and sending a reference signal for downlink beam management.

[0223] In this embodiment, when the network device determines that it can switch to the candidate beam, it can directly instruct the terminal to switch to the candidate beam by sending the fifth information to the terminal; or, when the network device determines that downlink beam management is required, for example, downlink beam measurement and reporting of downlink beam measurement results are required, it can send the fifth information to the terminal, and the fifth information includes configuration information for downlink beam management and a reference signal for downlink beam management. After receiving the fifth information, the terminal can perform downlink beam management operations according to the configuration information and the reference signal, for example, measure the reference signal according to the configuration information to obtain the resource quality of the reference signal.

[0224] In one implementation, the network device may send fifth information via downlink control information (DCI), where the fifth information indicates the beam identifier of the candidate beam or the resource identifier corresponding to the second measurement object to instruct the terminal to switch to the candidate beam; after receiving the fifth information, the terminal may use the candidate beam as the beam for subsequent uplink and downlink communications.

[0225] As an example, the terminal reports the beam identifier CRI2 of the candidate beam and the resource quality RSRP2 of the second measurement object on the PUSCH resource configured by the network device, indicating that the candidate beam CRI2 is the recommended beam for switching; after receiving the terminal report, the network device sends a signaling DCI, in which the resource identifier CSI-RS2 of the second measurement object is received; after receiving the instruction from the network device, the terminal can use the uplink and downlink data / signals received by the beam receiving CSI-RS2 after multiple orthogonal frequency-division multiplexing (OFDM).

[0226] In another implementation, when the channel resource used for the first information is a configured PRACH resource, the network device can send the fifth information through the PDCCH in the resource space defined corresponding to beam management. If the terminal detects the fifth information on the PDCCH, it can use the candidate beam as the beam for subsequent uplink and downlink communications.

[0227] In an embodiment of the present disclosure, after the terminal initiates beam management, the network device may feedback the fifth information to instruct the terminal to perform beam switching, or configure corresponding information for the terminal and instruct the terminal to perform downlink beam management according to the configured information, so as to obtain the channel state changes on the terminal side in a timely and accurate manner.

[0228] On the terminal side, an embodiment of the present disclosure provides a beam management device. As shown in FIG6 , the beam management device may include a transceiver 601 , a processor 602 , and a memory 603 .

[0229] The transceiver 601 is configured to receive and send data under the control of the processor 602 .

The bus interface provides an interface. The transceiver 601 may be a plurality of components, including a transmitter and a receiver, providing a unit for communicating with various other devices over a transmission medium, such as a wireless channel, a wired channel, an optical cable, or the like. In some embodiments, the beam management device further includes a user interface 604. For different user devices, the user interface 604 may also be an interface capable of connecting to required external or internal devices. Connected devices include, but are not limited to, a keypad, a display, a speaker, a microphone, a joystick, and the like.
