Description

Beam measurement method and related apparatus

[0001] The present application claims priority to the Chinese patent application No. 202411089118.6, filed on August 8, 2024, and entitled “Beam measurement method and related apparatus”, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, in particular to a beam measurement method and related apparatus. BACKGROUND

[0003] The fifth generation mobile communication system (5th generation, 5G) can use high frequency communication, that is, use ultra-high frequency band (such as 28 GHz) signal to transmit data. One of the main problems of high frequency communication is that the signal energy decreases sharply with the transmission distance, resulting in a short transmission distance. In order to overcome this problem, high frequency communication uses analog beam technology, which concentrates signal energy in a small angle range by weighting processing of antenna array, forming a signal similar to a light beam (called analog beam, simply referred to as beam), thereby improving the transmission distance. Both network devices and terminal devices use beams for transmission. When the network device and the terminal device perform uplink and downlink data transmission, a specific beam needs to be used.

[0004] The network device and the terminal device can select a suitable beam through a beam management process. Then the network device and the terminal device communicate through the selected beam. The terminal device can also continue to measure the signal quality of multiple beams configured by the network device for the terminal device. Then, the terminal device reports the signal quality of at least one beam with good signal quality measured by the terminal device according to the reporting resource configured by the network.

[0005] As can be seen, the terminal device measures multiple beams to obtain the signal quality of multiple beams, and reports the signal quality of multiple beams. The terminal device does not distinguish the types of multiple beams. This leads to the terminal device being unable to measure the signals of different types of beams specifically, and further leads to the terminal device being unable to select whether to report the measurement results in combination with the signal quality of different types of beams. SUMMARY

[0006] The present application provides a beam measurement method and related apparatus for a terminal device to measure reference signals corresponding to different types of beams. This facilitates the terminal device to determine whether to trigger measurement result reporting or select whether to report measurement results in combination with the measurement results of different types of beams. This avoids the first device reporting unnecessary measurement results and saves signaling overhead.

[0007] The first aspect of the present application provides a beam measurement method, which can be executed by a first device. The first device can be a terminal device, or a component (for example, a processor, a chip, or a chip system, etc.) in the terminal device, or a logic module or software capable of realizing all or part of the functions of the terminal device. The method can be used on the terminal side. The terminal device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, a chip system, a module, or a control unit in the foregoing devices or apparatuses, which are not limited in the present application. It should be noted that, in the present application, when referring to a terminal device, it can refer to the terminal device itself, or a chip, a functional module, or an integrated circuit in the terminal device that completes the method provided by the present application, which are not limited in the present application. The method comprises: the first device measures a serving beam and / or at least one new beam to obtain a first measurement result, the at least one new beam being a beam other than the serving beam of the first device; and the first device determines whether to trigger measurement result reporting according to the first measurement result.

[0008] In the above technical solution, the first device measures the serving beam and / or the at least one new beam to obtain the first measurement result. It can be known that the first device measures different types of beams. The first device determines whether to trigger measurement result reporting according to the first measurement result. The first device determines whether to trigger measurement result reporting or selects whether to report the measurement result in combination with the measurement results of different types of beams. The unnecessary measurement result reporting of the first device is avoided, and the signaling overhead is saved.

[0009] Optionally, the first device determines whether to report the measurement result according to the first measurement result, which can be alternatively described as: the first device determines whether to trigger the sending of the first uplink signaling or determines whether to send the first uplink signaling according to the first measurement result, the first uplink signaling being used to request the network device to schedule the second uplink signaling, or in other words, the first uplink signaling being used to request the network device to schedule the second uplink resource for the terminal device; or the first device determines whether to trigger the sending of the third uplink signaling or determines whether to send the third uplink signaling according to the first measurement result, the third uplink signaling being used to notify the network device that the terminal device will send the measurement result through the fourth uplink signaling. Or in other words, the third uplink signaling is used to notify the network device that the terminal device will send the measurement result through the fourth uplink resource; or the first device determines whether to trigger the reporting of the second measurement result according to the first measurement result, the second measurement result being part or all of the measurement results in the first measurement result.

[0010] Optionally, in the first aspect, the serving beam can be replaced by a transmission configuration indicator (TCI) state, a serving beam measurement resource, a reference signal resource, a first beam measurement resource, a first measurement resource, or a resource corresponding to the serving beam. The new beam can be referred to as a TCI state, a new beam measurement resource, a reference signal resource, a second beam measurement resource, a second measurement resource, or a resource corresponding to the new beam. The specific application does not make any limitation.

[0011] Based on the first aspect, in a possible implementation, the first device determines whether to trigger the measurement result reporting according to the first measurement result, including: if the first measurement result represents that a first event occurs, the first device performs an operation on a first timer and / or performs an operation on a first counter, wherein the first event is that the signal quality of the serving beam is less than a first threshold value, or the first event is that the signal quality of the serving beam is less than or equal to the first threshold value; the first timer is a timer corresponding to the serving beam, and the first counter is a counter corresponding to the serving beam; and the first device determines whether to trigger the measurement result reporting according to the state of the first timer and / or the state of the first counter. In this implementation, when the first event occurs, the first device performs an operation on the first timer and / or performs an operation on the first counter. Then the first device determines whether to trigger the measurement result reporting according to the state of the first timer and / or the state of the first counter. This realizes the first device to judge whether to report the measurement result to the second device. This realizes the on-demand reporting of the measurement result, saves the signaling overhead, and reduces the waste of transmission resources.

[0012] In a possible implementation of the first aspect, in a case where the first measurement result indicates that the first event occurs, the first device performs an operation on the first timer and / or performs an operation on the first counter, including: in a case where a first condition is met and the first measurement result indicates that the first event occurs, the first device performs an operation on the first timer and / or performs an operation on the first counter; and the first condition includes at least one of the following: the first device reports that the first device supports triggering measurement result reporting based on a state of a timer and / or a state of a counter, the first device reports that the first device supports reporting measurement result based on a state of a timer and / or a state of a counter, the second device configures the first device to trigger measurement result reporting based on a state of a timer and / or a state of a counter, the second device configures the first device to report measurement result based on a state of a timer and / or a state of a counter, the first device supports reporting measurement result in a first mode, or the second device configures the first device to report measurement result in the first mode, and the first mode includes: when a number of times that an event occurs within a preset time is greater than or equal to a second threshold, the first device triggers measurement result reporting. In this implementation, when the terminal device uses the first mode and the first event occurs, the first device performs an operation on the first timer and / or performs an operation on the first counter. The first device determines whether to trigger measurement result reporting based on a state of the first timer and / or a state of the first counter. The first device determines whether to report measurement result to the second device.

[0013] Optionally, the first device determining whether to trigger measurement result reporting based on the state of the first timer and / or the state of the first counter can be alternatively described as: the first device determining whether to report measurement result based on the state of the first timer and / or the state of the first counter, or the first device determining whether to trigger sending of first uplink signaling or determining whether to send the first uplink signaling, the first uplink signaling being used to request the network device to schedule second uplink signaling, or the first uplink signaling being used to request the network device to schedule a second uplink resource for the terminal device; or the first device determining whether to trigger sending of third uplink signaling or determining whether to send the third uplink signaling, the third uplink signaling being used to notify the network device that the terminal device will send measurement result through fourth uplink signaling, or the third uplink signaling being used to notify the network device that the terminal device will send measurement result through a fourth uplink resource; or the first device determining whether to trigger measurement result reporting corresponding to the first event based on the state of the first timer and / or the state of the first counter; or the first device determining whether to report measurement result corresponding to the first event based on the state of the first timer and / or the state of the first counter.

[0014] Optionally, the first mode comprises: when the number of times that the first event occurs within the preset time is greater than or equal to the second threshold value, the first device reports the measurement result, or the first device sends the measurement result corresponding to the first event, or the first device triggers the sending of the first uplink signaling or the third uplink signaling, or the first device sends the first uplink signaling or the third uplink signaling. For the first uplink signaling and the third uplink signaling, refer to the foregoing description.

[0015] Based on the first aspect, in a possible implementation, the operation performed by the first device on the first timer comprises: the first device starting or restarting the first timer. When the first event occurs or after the first event occurs, the first timer is started or restarted, so as to start timing.

[0016] Based on the first aspect, in a possible implementation, the operation performed by the first device on the first counter comprises: the first device increasing the value of the first counter by one. When the first event occurs once, it is recorded once. This facilitates the recording of the number of times that the first event occurs.

[0017] Based on the first aspect, in a possible implementation, before the operation performed by the first device on the first timer and / or the operation performed by the first device on the first counter, the method further comprises: the physical layer of the first device sending first indication information to the media access control (MAC) layer of the first device, the first indication information being used to indicate that the first event occurs. In this implementation, the physical layer and the MAC layer of the first device jointly determine whether to trigger the reporting of the measurement result. This implements on-demand reporting of the measurement result.

[0018] Based on the first aspect, in a possible implementation, the first indication information is further used to indicate at least one of the following: an event index corresponding to the first event, an event type corresponding to the first event, or information of a serving beam, wherein the information of the serving beam comprises at least one of the following: an index of the serving beam, or a signal quality of the serving beam. In this implementation, the first indication information can further indicate the information of the first event and the information of the serving beam. This facilitates the MAC layer of the first device to determine whether to trigger the reporting of the measurement result in combination with the information. Of course, the information can also be indicated by other indication information, which is not limited in the present application.

[0019] In a possible implementation of the first aspect, in a possible implementation, the first device determines whether to trigger reporting of the measurement result according to the state of the first timer and / or the state of the first counter, including: if the value of the first counter is greater than or equal to a third threshold value before the first timer expires, the first device triggers reporting of the measurement result; or, if the value of the first counter is greater than or equal to the third threshold value before the first timer expires, the first device reports the measurement result. Or, if the value of the first counter is greater than or equal to the third threshold value before the first timer expires, the first device triggers sending of first uplink signaling or third uplink signaling, the first uplink signaling being used to request the network device to schedule second uplink signaling, or the first uplink signaling being used to request the network device to schedule a second uplink resource for the terminal device; the third uplink signaling being used to inform the network device that the terminal device will send the measurement result through fourth uplink signaling, or the third uplink signaling being used to inform the network device that the terminal device will send the measurement result through a fourth uplink resource. Or, if the value of the first counter is greater than or equal to the third threshold value before the first timer expires, the first device sends the first uplink signaling or the third uplink signaling; or, if the value of the first counter is greater than or equal to the third threshold value before the first timer expires, the first device reports the measurement result corresponding to a first event, the measurement result corresponding to the first event belonging to the first measurement result. In this implementation, if the number of occurrences of the first event is greater than or equal to the third threshold value within a time length set by the first timer, the first device triggers reporting of the measurement result. This implementation realizes reporting of the measurement result on demand, and reduces waste of resources. The above implementation can be alternatively described as: if the value of the first counter is greater than the third threshold value before the first timer expires, the first device triggers reporting of the measurement result.

[0020] In a possible implementation of the first aspect, the third threshold value is an integer greater than or equal to 1 if the first condition is met, or the third threshold value is 1 by default if the first condition is not met, where the first condition includes at least one of the following: the first device reporting that the first device supports triggering measurement reporting based on a timer-based state and / or a counter-based state, the first device reporting that the first device supports measurement reporting based on a timer-based state and / or a counter-based state, the second device configuring the first device to trigger measurement reporting based on a timer-based state and / or a counter-based state, the second device configuring the first device to report measurement based on a timer-based state and / or a counter-based state, the first device supporting a first mode for reporting measurement, or the second device configuring the first device to use the first mode for reporting measurement, where the first mode includes triggering measurement reporting by the first device when a number of occurrences of a first event within a preset time period is greater than or equal to a second threshold value, or the first mode includes reporting measurement by the first device when the number of occurrences of the first event within the preset time period is greater than or equal to the second threshold value, or the first mode includes sending, by the first device, measurement corresponding to the first event, or the first mode includes triggering, by the first device, sending of a first uplink signaling or a third uplink signaling, or the first mode includes sending, by the first device, the first uplink signaling or the third uplink signaling. The first uplink signaling and the third uplink signaling can be referred to the foregoing description. In this implementation, if the terminal device uses the first mode, the third threshold value can be greater than or equal to 1. If the terminal device does not use the first mode, for example, the terminal device uses a second mode, the third threshold value is 1 by default. This indicates that when the first event occurs, the first device triggers measurement reporting.

[0021] In a possible implementation of the first aspect, the method further includes: after the first device performs measurement reporting, the first device closes the first timer, and / or the first device sets the first counter to 0. This facilitates the first device to continue monitoring the first event, and when the first event occurs, the first timer and the first counter can be operated accordingly.

[0022] In a possible implementation of the first aspect, the method further includes: after the first timer expires, the first device sets the first counter to 0. This facilitates the first device to record the number of occurrences of the first event again after restarting the first timer.

[0023] In a possible implementation manner of the first aspect, when the serving beam changes, the method further includes: the first device stops or closes the first timer, and / or the first device sets the first counter to 0. In order to facilitate the first device to re-monitor the signal quality of the changed serving beam. The first device can determine whether the first event occurs according to the signal quality of the changed serving beam, and when the first event occurs, the first device can perform corresponding operations on the first timer and / or the first counter. The first device determines whether to trigger the measurement result reporting based on the state of the first timer and / or the state of the first counter. The measurement result is reported on demand.

The first uplink signaling and the third uplink signaling can be referred to the foregoing description. The first event is that the signal quality of the serving beam is less than the first threshold. Or, if the MAC layer of the first device receives the first indication information sent by the physical layer of the first device, the first indication information is used to indicate that the first event occurs, and the first event is that the signal quality of the serving beam is less than the first threshold, the MAC layer of the first device triggers the measurement result reporting, or the MAC layer of the first device triggers the physical layer of the first device to report the measurement result, or the MAC layer of the first device triggers the physical layer of the first device to report the measurement result corresponding to the first event, or the MAC layer of the first device triggers the physical layer of the first device to send the first uplink signaling or the third uplink signaling. The first uplink signaling and the third uplink signaling can be referred to the foregoing description. In this implementation manner, two other ways for the first device to determine whether to trigger the measurement result reporting are shown. In one possible implementation, when the first event occurs, the physical layer of the first device directly triggers the measurement result reporting. In another possible implementation, when the first event occurs, the physical layer of the first device sends the first indication information to the MAC layer of the first device, and the MAC layer of the first device triggers the measurement result reporting based on the first indication information, or the MAC layer of the first device triggers the physical layer of the first device to report the measurement result based on the first indication information, or the MAC layer of the first device triggers the physical layer of the first device to report the measurement result corresponding to the first event based on the first indication information, or the MAC layer of the first device triggers the physical layer of the first device to send the first uplink signaling or the third uplink signaling based on the first indication information. The first uplink signaling and the third uplink signaling can be referred to the foregoing description. The first device reports the measurement result on demand.

[0025] In a possible implementation of the first aspect, if the first measurement result represents occurrence of the first event, the first device triggers measurement result reporting, including: if the first condition is not met and the first measurement result represents occurrence of the first event, the first device triggers measurement result reporting, or the first device reports the measurement result belonging to the first measurement result, or the first device reports the measurement result corresponding to the first event, or the first device triggers sending of the first uplink signaling or the third uplink signaling, or the first device sends the first uplink signaling or the third uplink signaling, which can be referred to the foregoing description. The first condition includes at least one of the following: the first device reports that the first device supports triggering measurement result reporting based on a timer state and / or a counter state, the first device reports that the first device supports reporting measurement result based on a timer state and / or a counter state, the second device configures the first device to trigger measurement result reporting based on a timer state and / or a counter state, the second device configures the first device to report measurement result based on a timer state and / or a counter state, the first device supports reporting measurement result in a first mode, or the second device configures the first device to report measurement result in the first mode, the first mode including: when a number of occurrences of an event within a preset time is greater than or equal to a second threshold, the first device triggers measurement result reporting. Or, if the MAC layer of the first device receives first indication information sent by the physical layer of the first device, the MAC layer of the first device triggers measurement result reporting, including: if the first condition is not met and the MAC layer of the first device receives the first indication information sent by the physical layer of the first device, the MAC layer of the first device triggers measurement result reporting, or the MAC layer of the first device triggers the physical layer of the first device to report measurement result, or the MAC layer of the first device triggers the physical layer of the first device to report the measurement result corresponding to the first event, or the MAC layer of the first device triggers the physical layer of the first device to send the first uplink signaling or the third uplink signaling, which can be referred to the foregoing description.

In the implementation, when the second event occurs, the first device performs an operation on the second timer, and / or, the first device performs an operation on the second counter. Then the first device determines whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter. This realizes the first device determining whether to report the measurement result to the second device. This realizes the measurement result reporting on demand, saves the signaling overhead, and reduces the waste of transmission resources.

[0028] In the implementation, optionally, the first device determining whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter can also be replaced by: the first device determining whether to report the measurement result according to the state of the second timer and / or the state of the second counter; or the first device determining whether to trigger the measurement result reporting corresponding to the second event according to the state of the second timer and / or the state of the second counter; or the first device determining whether to report the measurement result corresponding to the second event according to the state of the second timer and / or the state of the second counter; or the first device determining whether to trigger the sending of the first uplink signaling or the third uplink signaling according to the state of the second timer and / or the state of the second counter; or the first device determining whether to send the first uplink signaling or the third uplink signaling according to the state of the second timer and / or the state of the second counter.

[0030] In a possible implementation of the first aspect, the first device performs the operation on the second timer corresponding to the new beam that meets the occurrence condition of the second event, including: for any new beam that meets the occurrence condition of the second event, the first device starts or restarts the second timer corresponding to the new beam. In this implementation, the new beam that meets the occurrence condition of the second event is one or more. The first device performs the operation on the second timer corresponding to the new beam that meets the occurrence condition of the second event, including: for one new beam that meets the occurrence condition of the second event, the first device starts or restarts the second timer corresponding to the new beam. When the second event occurs or after the second event occurs, the second timer is started or restarted, and thus the timing is started.

In this implementation, the physical layer and the MAC layer of the first device jointly determine whether to trigger the measurement result reporting. The measurement result is reported on demand.

[0035] In a possible implementation of the first aspect, the second indication information further indicates at least one of the following: an event index corresponding to the second event, an event type corresponding to the second event, information of the serving beam, or information of the new beam satisfying the occurrence condition of the second event; the information of the serving beam includes at least one of the following: an index of the serving beam, or a signal quality of the serving beam; the information of the new beam satisfying the occurrence condition of the second event includes at least one of the following: an index of the new beam satisfying the occurrence condition of the second event, a signal quality of the new beam satisfying the occurrence condition of the second event, or a signal quality difference between the new beam satisfying the occurrence condition of the second event and the serving beam.

For example, a handheld device having a wireless connection function, a vehicle mounted device, a machine type communication (MTC) terminal, etc. Currently, a terminal device can include a mobile phone, a tablet computer, a notebook computer, a palm computer, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self driving (e.g., a drone, a vehicle), a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, or a wireless terminal in a smart home, etc. For example, a wireless terminal in self driving can be a drone, a helicopter, or an airplane, etc. For example, a wireless terminal in vehicle to everything (V2X) can be a vehicle mounted device, an on-board device, a vehicle mounted module, a vehicle, or a ship, etc. A wireless terminal in industrial control can be a camera, a robot, or a mechanical arm, etc. A wireless terminal in a smart home can be a television, an air conditioner, a sweeping machine, a sound box, or a set-top box, etc. A terminal device can also be a device or a module having a corresponding communication function accessing the above-mentioned communication system. A terminal device is usually provided with a communication module, a circuit or a chip for performing a corresponding communication function, and is also configured with program instructions for performing a corresponding communication function.

[0161] It should be noted that a terminal device can be a device or an apparatus with a chip, or a device or an apparatus integrated with a circuit, or a chip, a chip system, a module or a control unit in the above-mentioned device or apparatus, and the specific application is not limited. It should be noted that in the present application, when referring to a terminal device, it can refer to the terminal device itself, or a chip, a functional module or an integrated circuit in the terminal device for completing the method provided in the present application, and the specific application is not limited.

[0162] A network device is a device deployed in a wireless access network to provide wireless communication functions for terminal devices. The network device can also be referred to as a radio access network (RAN) entity, an access node, a network node, an access network device, or a communication apparatus, etc.

[0163] Specifically, the network device can be an access network device of a 3rd generation partnership project (3GPP) related cellular system. For example, a fourth-generation (4G) mobile communication system, a 5G mobile communication system, or a future mobile communication system. The network device can also be an access network device in an ORAN or a cloud radio access network (CRAN). Alternatively, the network device can also be an access network device in a communication system obtained by fusing two or more of the above communication systems.

[0164] The network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (for example, a home evolved NodeB, or home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WiFi) system, a macro base station, a micro base station, a wireless relay node, a donor node, a wireless controller in a CRAN scenario, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP). The network device can also be an access network device in a 5G mobile communication system. For example, a next generation NodeB (gNB) in a new radio (NR) system, a TRP, a TP, or one or a group (including multiple antenna panels) of antenna panels of a base station in a 5G mobile communication system. Alternatively, the network device can also be a network node constituting a gNB or a transmission point. For example, a centralized 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. For example, a BBU. The RU can be included in a radio frequency device or a radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the network device can also be a server, a wearable device, a vehicle or a vehicle-mounted device, etc. For example, in V2X technology, the network device can be a road side unit (RSU).

[0165] It should be noted that 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 the ORAN system, the CU can also be referred to as an open centralized unit (O-CU) or an open CU, the DU can also be referred to as an open distributed unit (O-DU), the centralized unit control plane (CU-CP) can also be referred to as an open centralized unit control plane (O-CU-CP) or an open CU-CP, the centralized unit user plane (CU-UP) can also be referred to as an open centralized unit user plane (O-CU-UP) or an open CU-UP, and the RU can also be referred to as an open radio unit (O-RU). The specific application is not limited. Any one of the CU, CU-CP, CU-UP, DU and RU in the present application can be realized by a software module, a hardware module, or a combination of a software module and a hardware module.

[0166] FIG. 1 is a schematic diagram of an ORAN system according to an embodiment of the present application. The ORAN system includes a core network, an access network device and a UE. Optionally, the ORAN system can also include other components in addition to the components shown in FIG. 1, and the specific application is not limited.

[0167] The access network device can communicate with the core network (CN) through a backhaul link. The access network device can communicate with the UE through an air interface. Specifically, the BBU in the access network device communicates with the core network through the backhaul link. The RU in the access network device communicates with at least one UE through the air interface. The BBU communicates with at least one RU through a fronthaul link, and the BBU and the RU can be co-located or not co-located.

[0168] The BBU includes at least one CU and at least one DU, and the CU and the DU can communicate through at least one midhaul link.

[0169] In a possible implementation, as shown in FIG. 2, the CU is a logical node carrying radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer and other control functions of the access network device. The CU can be connected to network nodes such as a core network through some interfaces. For example, an E2 interface. Optionally, the CU can have part of the functions of the core network. The CU (for example, the PDCP layer and / or higher layer of the CU) is connected to the DU (for example, the radio link control (RLC) layer and lower layer of the DU) through some interfaces. For example, an F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (for example, interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is an application protocol of the F1 interface, which defines signaling procedures of the F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0170] Optionally, as shown in FIG. 2, the CU can be split into a CU-CP and a CU-UP, where the CU-CP is a logical node carrying the control plane part of PDCP (PDCP-C) layer of RRC layer and packet data convergence protocol layer, used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network for implementing the control plane function. The network element in the core network for implementing the control plane function can be an access and mobility function network element, such as an access and mobility management (AMF) in a 5G system. The AMF network element is used to be responsible for mobility management in a mobile network, such as location update of a terminal device, registration network of the terminal device, handover of the terminal device, and the like. The CU-UP is a logical node carrying the user plane part of PDCP (PDCP-U) layer of SDAP layer and packet data convergence protocol layer, used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network for implementing the user plane function. The network element in the core network for implementing the user plane function, for example, a user plane function (UPF) in a 5G system, is used to be responsible for forwarding and receiving data in a terminal device. The above configuration of the CU and the DU is only an example, and in actual application, the CU and the DU can also be configured to have functions according to needs. For example, the CU or the DU can be configured to have more functions of protocol layers, or the CU or the DU can be configured to have partial processing functions of protocol layers. For example, partial functions of the RLC layer and functions of protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to service types or other system requirements, for example, functions that need to meet a relatively short delay requirement in processing time are arranged in the DU, and functions that do not need to meet the delay requirement are arranged in the CU.

[0171] In a possible implementation manner, as shown in FIG. 2, the DU is a logical node carrying the RLC layer, the MAC layer, the higher physical (Higher PHY) layer, and other functions. In some examples, the DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be a front-haul interface. In some examples, the Higher PHY layer includes part of the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like.

[0172] In one possible implementation, as shown in FIG. 2, the RU is a logical node that hosts the lower physical (Lower PHY) layer and radio frequency (RF) processing. In some examples, the RU can be a 3GPP TRP or a remote radio head (RRH) or other similar functional entity. In some examples, the Low-PHY includes portions of the PHY processing such as fast fourier transform (FFT), inverse fast fourier transformation (IFFT), digital beamforming and filtering, and other processing functions. The RU communicates with one or more UEs over a wireless link.

[0173] The DU and the RU can or can not be co-located. The DU and the RU exchange control plane information and user plane information via a lower-layer split-control, user and synchronization (Lower-Layer Split CUS-Plane, LLS-CUS) interface over a fronthaul link. The LLS-CUS can include a lower-layer split control (LLS-C) interface and a lower-layer split user (LLS-U) interface that provide control plane (C-Plane) and user plane (U-Plane), respectively. In some examples, the control plane (C-Plane) refers to real-time control between the DU and the RU. The DU and the RU exchange management information via a lower-layer split management (LLS-M) interface of the fronthaul link, and the management plane (M-Plane) refers to non-real-time management operations between the DU and the RU.

[0174] The DU and the RU can cooperate to collectively implement the functionality of the PHY layer. One DU can be connected to one or more RUs. The functionalities of the DU and the RU can be configured in multiple ways according to design. For example, the DU is configured to implement baseband functionality, and the RU is configured to implement mid- RF functionality. As another example, the DU is configured to implement high-layer functionality in the PHY layer, and the RU is configured to implement low-layer functionality in the PHY layer or to implement the low-layer functionality and RF functionality. The high-layer functionality in the PHY layer can include a portion of the functionality of the PHY layer that is closer to the MAC layer, and the low-layer functionality in the PHY layer can include another portion of the functionality of the PHY layer that is closer to the mid-RF side.

[0175] The CU (or CU-CP and CU-UP), DU or RU can also have different names in different systems, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be referred to as O-CU (open CU), the DU can also be referred to as O-DU, the CU-CP can also be referred to as O-CU-CP, the CU-UP can also be referred to as O-CU-UP, and the RU can also be referred to as O-RU. For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in the present application.

[0176] It should be noted that the network device can be a device or apparatus with a chip, or a device or apparatus integrated with a circuit, or a chip, chip system, module or control unit in the above-mentioned device or apparatus, and the specific application is not limited. It should be noted that in the present application, when referring to the network device, it can refer to the network device itself, or the chip, functional module or integrated circuit in the network device that completes the method provided in the present application, and the specific application is not limited.

[0177] In order to facilitate understanding of the technical solutions of the embodiments of the present application, two possible communication systems to which the method provided by the embodiments of the present application is applicable are shown in FIGS. 3 and 4.

[0178] FIG. 3 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in FIG. 3, the communication system includes at least one network device and at least one terminal device. For example, as shown in FIG. 3, the network device 311, the terminal device 321 and the terminal device 322. The network device 311 can perform transmission with the terminal device 321 and the terminal device 322. The network device 311 and the terminal device 321 or the terminal device 322 can perform the technical solutions of the present application.

[0179] FIG. 4 is another schematic diagram of a communication system according to an embodiment of the present application. As shown in FIG. 4, the communication system can include at least two network devices and at least one terminal device. For example, as shown in FIG. 4, the network device 411, the network device 412, the network device 413 and the terminal device 421. The terminal device 421 can be provided with communication services by multiple network devices. For example, as shown in FIG. 4, the network device 411 can perform transmission with the terminal device 421, the network device 412 can perform transmission with the terminal device 421. The network device 413 can perform transmission with the terminal device 421. That is, one terminal device can be simultaneously provided with communication services by multiple network devices. The terminal device 421 and the network device 411, the network device 412 or the network device 413 can perform the technical solutions of the present application.

[0180] In order to facilitate understanding of the technical solutions of the present application, some technical terms related to the present application are introduced below.

[0181] 1. Beam: A beam is a kind of communication resource. A beam can be a wide beam, or a narrow beam, or other types of beams, and the technology to form a beam can be beamforming technology or other technology means. The beamforming technology can be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources.

[0182] A beam can be referred to as a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, quasi-colocation (QCL) information, a QCL assumption, a QCL indication, or the like in the NR protocol. A beam can be indicated by a transmission configuration indicator state (TCI-state) parameter or a spatial relation parameter. Therefore, in this application, a beam can be replaced by a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, a QCL assumption, a QCL indication, a TCI-state (including uplink TCI-state and downlink TCI-state), or a spatial relation, etc. The above terms are also equivalent to each other. A beam can also be replaced by other terms representing a beam, which are not limited in this application.

[0183] A beam used for transmitting a signal can be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The transmission beam can also be referred to as a downlink beam. In this application, the transmission beam, the downlink beam, the channel state information reference signal (CSI-RS), the TCI State, the downlink / joint transmission configuration indication state (DL or joint TCI state), the synchronization signal and PBCH block (SS / PBCH, referred to as SSB), and the tracking reference signal (TRS) can be replaced with each other.

[0184] A beam for receiving a signal can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. An uplink transmission beam can be indicated by any one of a spatial relationship, an uplink TCI-state, a sounding reference signal (SRS) resource (indicating a transmission beam using the SRS). A reception beam can also be referred to as an uplink beam. In this application, a reception beam, an uplink beam, an uplink transmission configuration indication state (UL TCI state), a DL or joint TCI state, an SRS, a CSI-RS, an SSB, and a TRS can be replaced with each other.

[0185] A transmission beam can refer to a distribution of signal strength in different directions in space after a signal is transmitted by an antenna, and a reception beam can refer to a distribution of signal strength in different directions in space of a wireless signal received by an antenna.

[0186] In addition, a beam can be a wide beam, or a narrow beam, or other types of beams. The technology for forming a beam can be beamforming technology or other technology. The beamforming technology can be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology, etc.

[0187] A beam is generally associated with a resource. For example, when performing beam measurement, a network device measures different beams through different resources, and a terminal device feeds back the measured resource quality, so that the network device knows the quality of the corresponding beam. When data is transmitted, beam information is also indicated through its corresponding resource. For example, a network device indicates the information of a physical downlink shared channel (PDSCH) beam of a terminal device through a TCI field in downlink control information (DCI).

[0188] In one possible implementation, multiple beams with the same or similar communication characteristics are considered as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, sounding signals, and the like. One or more antenna ports forming one beam can also be considered as one antenna port set.

[0189] 2、QCL: Quasi Co-Location is used to indicate that multiple resources have one or more same or similar communication characteristics. For multiple resources with quasi co-location, the same or similar communication configuration can be used. For example, if two antenna ports have quasi co-location, the channel large-scale characteristics of one port transmitting one symbol can be inferred from the channel large-scale characteristics of another port transmitting one symbol. The large-scale characteristics can include: delay spread, average delay, Doppler spread, Doppler shift, average gain, reception parameters, terminal device reception beam number, transmission / reception channel correlation, reception angle of arrival, spatial correlation of receiver antennas, main angle of arrival (AoA), average angle of arrival, spread of AoA, and the like. Specifically, the co-location indication is used to indicate whether at least two groups of antenna ports have co-location relationship, including: the co-location indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same transmission point, or the co-location indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same beam group.

[0190] 3、TCI: Also known as TCI-state. In uplink and downlink transmission, both the network device and the terminal device need to use the correct beam to achieve correct transmission. In downlink transmission, the network device needs to indicate the downlink transmission beam it uses to the terminal device. The terminal device can determine the appropriate reception beam according to the downlink transmission beam, which is used to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink transmission beam the terminal device uses to send information to the network device. The network device can determine the uplink transmission beam with better signal quality of the terminal device. Both the uplink transmission beam and the downlink transmission beam can be indicated by the corresponding TCI state. Specifically, the downlink transmission beam can be indicated by the downlink TCI state, and the uplink transmission beam can be indicated by the uplink TCI state.

[0191] In the 3GPP protocol, the network device can indicate the TCI state to the terminal device through the TCI field in the downlink control information (DCI). The size of the TCI field is 3 bits, which can be specifically represented as 8 different field values (codepoints). Each field value of the TCI field can be associated with an identification of a TCI state. The identification of the TCI state can uniquely identify a TCI state, which can be a downlink TCI state or an uplink TCI state. Each field value of the TCI field can also be associated with two TCI state identifications, which can uniquely identify two TCI states, which can include a downlink TCI state and an uplink TCI state.

[0192] The downlink TCI state includes several parameters, and the terminal device can determine the related information of the downlink transmission beam through these parameters, so as to determine to use a suitable receiving beam to receive information from the network device. The TCI state is configured by the network device to each terminal device, and the structure of the downlink TCI state is as follows:

[0193] Each TCI state includes its own identification (tci-StateId) and two quasi-colocation information (QCL-info). Each QCL-info includes a reference signal resource, which is used to indicate that the downlink transmission of the TCI state should use the same downlink timing, frequency offset or receiving beam as the reference signal resource. The specific type of the QCL-info determines it. The QCL type can have four values {typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB and typeC, the same downlink timing and frequency offset as the reference signal resource should be used for downlink transmission. When the QCL type is typeD, the same receiving beam as the reference signal resource should be used for downlink transmission. In the above two QCL-info, one is typeD and the other is typeA or typeB or typeC. The terminal device can determine which receiving beam to use to receive the corresponding downlink transmission through the QCL-info of typeD. The specific execution steps are as follows:

[0194] The network device indicates a certain downlink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the typeD QCL information of the downlink TCI state. The terminal device takes the receiving beam of the reference signal resource as the receiving beam for downlink transmission. It should be noted that the receiving beam of the reference signal resource is obtained by the terminal device in advance through the beam management process. Through the beam management process, the terminal device can determine which receiving beam is the best to receive the reference signal resource, and take the receiving beam as the receiving beam of the reference signal resource.

[0195] The uplink TCI state includes a reference signal resource, which is used to indicate that the uplink transmission using the TCI state should use the same uplink sending beam as the reference signal resource. The terminal device can determine which sending beam to use for uplink transmission through the reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info, nor is it distinguished by the QCL type, because it is not necessary to refer to the uplink timing and frequency offset information, but only to the uplink sending beam. The structure of the uplink TCI state is as follows:

[0196] The specific execution steps are as follows:

[0197] The network device indicates a certain uplink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the uplink TCI state. The terminal device takes the sending beam of the reference signal resource as the sending beam for uplink transmission. It should be noted that the sending beam of the reference signal resource is obtained by the terminal device in advance through the beam management process.

[0198] The configuration, activation and indication of the TCI state are introduced below.

[0199] TCI-state configuration: The network device configures multiple TCI-states to the terminal device through RRC signaling. These TCI-states all include a typeD QCL-Info. The network device can also configure TCI-states that do not include typeD QCL-info, but these TCI-states are not used for data transmission beam indication, so they are not further described here.

[0200] TCI-state activation: after the network device configures multiple TCI-states, it also needs to activate 8 of them through a media or medium access control control element (MAC CE). The 8 TCI-states are one-to-one corresponding to the 8 values of the TCI field in the DCI. That is, which 8 TCI-states correspond to the 8 values of the TCI field in the DCI is determined through the MAC CE.

[0201] TCI state indication: the network device indicates a specific TCI-state through the TCI field in the DCI. For example, the value of the TCI field in the DCI sent by the network device to the terminal device is 000, indicating that the data transmission beam adopts the TCI state corresponding to 000. The reference signal contained in the typeD QCL-Info in the TCI state is the CSI-RS with index #1, indicating that the data transmission beam is the same as the receiving beam corresponding to the CSI-RS with index #1. The receiving beam corresponding to the CSI-RS with index #1 can be determined through a beam measurement process and is known to the terminal device. Therefore, through the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam, and thus transmit or receive data using the corresponding beam.

[0202] It should be noted that the three descriptions of TCI state, TCI-state and TCI state in this paper can be replaced with each other. ID in this application can be translated as identifier, indication, indicator, index, identity, or identification. identifier, indication, indicator, index, identity, identification can be replaced with each other.

[0203] In this application, TCI can be translated as transmission configuration indication or transmission configuration number. The English translation of transmission configuration indication is transmission configuration indicator or transmission configuration indication.

[0204] Currently, a terminal device and a network device select a proper beam through a beam management procedure and communicate through the selected beam. The beam management procedure includes: first beam coarse alignment based on SSB and then beam fine adjustment based on CSI-RS. The beam management procedure can be divided into three stages, which are introduced as follows.

[0205] Stage one: coarse beam alignment between the network device and the terminal device.

[0206] The base station performs beam sweeping. Specifically, as shown in FIG. 5a, the base station transmits SSBs to the terminal device through beams in different directions at different times. At the same time, the terminal device sweeps the receiving beam, that is, the terminal device also receives SSBs from the network device through beams in different directions at different times. The terminal device determines the better beam for the base station to transmit signals and the better beam for the terminal device to receive signals according to the received signal strength. The beam for the base station to transmit signals is referred to as the base station beam, and the beam for the terminal device to receive signals is referred to as the terminal beam.

[0207] Specifically, the base station beam includes The terminal beam includes As shown in FIG. 5b, the base station transmits SSB resource configuration information and reporting resource configuration information to the terminal device. The base station beam includes beams B0 to B5, that is, M = 5. The terminal beam includes beams U0 to U3, that is, N = 4. The base station transmits SSBs to the terminal device through corresponding SSB resources using beam B0, transmits SSBs to the terminal device using beam B1, and so on, and transmits SSBs to the terminal device using beam B5. The terminal device measures the SSBs transmitted by the base station through beams B0 to B5 respectively through beams U0 to U3 respectively, and obtains measurement results. The terminal device can determine the base station beam with better or best signal quality through the measurement results. The terminal device feeds back the base station beam with better or best signal quality to the network device. It should be noted that in stage one, the base station beam and the terminal beam can be understood as wide beams.

[0208] Stage two: base station beam fine adjustment.

[0209] The base station determines a plurality of first candidate beams according to the base station beam with better or best signal quality determined in stage one, each of the first candidate beams being a narrow beam. Specifically, as shown in FIG. 6a, the plurality of first candidate beams includes beams S0 to S2. For example, the base station determines the beam B3 in the above-mentioned stage one, the beam B3 being a wide beam, and the base station determines the beams S0 to S2 through the beam B3. The terminal device determines the better terminal beam as the beam U1 through the above-mentioned stage one. As shown in FIG. 6b, the base station sends the CSI-RS configuration information to the terminal device. The network device sends the CSI-RS to the terminal device through the corresponding CSI-RS resource using the beam S0, sends the CSI-RS to the terminal device through the corresponding CSI-RS resource using the beam S1, and sends the CSI-RS to the terminal device through the corresponding CSI-RS resource using the beam S2. The terminal device receives the CSI-RS sent from the base station through different beams through the beam U1 and obtains measurement results. The terminal device can determine the candidate beam with better or best signal quality through the measurement results. The terminal device feeds back the first candidate beam with better or best signal quality to the network device. For example, as shown in FIG. 6c, the first candidate beam with better or best signal quality is the beam S1. The base station takes the first candidate beam with better or best signal quality as the beam for communicating with the terminal device.

[0210] Stage three: UE beam refinement.

[0211] The base station sends the CSI-RS to the terminal device using the beam S1, while the terminal device determines the better terminal beam as the beam U1 through the above-mentioned stage one, the beam U1 being a wide beam. The terminal device determines a plurality of second candidate beams through the beam U1, as shown in FIG. 6c, the plurality of second candidate beams including beams P1 to P4. The terminal device receives the CSI-RS sent from the base station through the beam S1 through the beams P1 to P4 and obtains measurement results. The terminal device can select one beam from the beams P1 to P4 according to the measurement results and take the beam as the beam for communicating with the network device.

[0212] The network device can configure the terminal device to report the measurement results in one of the following three ways. The three ways specifically include: periodic reporting, semi-persistent reporting, and aperiodic reporting. The semi-persistent reporting is also referred to as semi-static reporting.

[0213] Periodic reporting: the network device sends reference signal resource configuration information to the terminal device. The reference signal resource configuration information includes periodic reference signal resources. The network device configures periodic measurement reference signals for the terminal device. The terminal device can measure the periodic measurement reference signals based on the reference signal resource configuration information, and periodically report measurement results. Optionally, the measurement results obtained by the terminal device for the periodic measurement reference signals can be carried on a physical uplink control channel (PUCCH) resource.

[0214] Semi-persistent reporting: the terminal device measures periodic reference signals, but reports measurement results in a semi-persistent manner. In one possible implementation, the network device sends reference signal resource configuration information to the terminal device. The reference signal resource configuration information includes periodic reference signal resources. The network device configures periodic measurement reference signals for the terminal device. When the terminal device receives activation signaling (for example, MAC CE or DCI) from the network device, the terminal device can continuously report measurement results. Of course, the network device can also send deactivation instructions to the terminal device, thereby deactivating the semi-persistent reporting process of the terminal device. In another possible implementation, both the measurement of the reference signal and the reporting of the measurement results are semi-persistent. When the terminal device receives activation signaling from the network device, the terminal device continuously measures the reference signal and reports the measurement results. When the terminal device receives deactivation instructions from the network device, the terminal device stops reporting the measurement results. In addition, the measurement results can be carried on a PUCCH resource or a physical uplink shared channel (PUSCH) resource.

[0215] Aperiodic reporting: when the terminal device receives a trigger instruction (for example, DCI) from the network device, the terminal device measures the reference signal and reports the measurement results. After completing the reporting, the terminal device stops reporting the measurement results. Optionally, the reference signal can be a periodic reference signal, a semi-persistent reference signal, or an aperiodic reference signal. Optionally, the measurement results are carried on a PUSCH resource.

[0216] From the above beam management process, it can be known that the network device and the terminal device can select a suitable beam through the beam management process. Then the network device and the terminal device communicate through the selected beam. The terminal device can also continue to measure the signal quality of the multiple beams configured by the network device for the terminal device. Then, the terminal device reports the signal quality of at least one beam with good signal quality measured by the terminal device according to the reporting resource configured by the network. It can be known that the terminal device measures multiple beams to obtain the signal quality of the multiple beams, and reports the signal quality of the multiple beams. The terminal device does not distinguish the types of the multiple beams. This leads to that the terminal device cannot measure the signals of different types of beams, and further leads to that the terminal device cannot select whether to report the measurement results in combination with the signal quality of different types of beams.

[0217] Before R18 and R18, the measurement result reporting process of the terminal device is dominated by the network device, that is, the network device decides when the terminal device reports the measurement results. This way leads to a large uplink resource overhead. Specifically, in the periodic reporting and semi-persistent reporting, the terminal device needs to report the measurement results every other period, and these measurement results may be meaningless to the network side. For example, the measurement results reported by the terminal device twice are not different (for example, the optimal beam does not change), and therefore the uplink resource is wasted. In R19, event triggered reporting is introduced, and the terminal device can report the beam measurement results related to the event. Therefore, how to trigger the measurement result reporting is a problem worth considering.

[0218] The present application provides corresponding technical solutions for the first device to measure a service beam and / or at least one new beam to obtain a first measurement result. The at least one new beam is a beam of the first device other than the service beam. Then, the first device determines whether to trigger the measurement result reporting according to the first measurement result. It can be known that the terminal device measures different types of beams. This facilitates the terminal device to determine whether to trigger the measurement result reporting or select whether to report the measurement result in combination with the measurement results of different types of beams. This is helpful to avoid the first device reporting unnecessary measurement results and save signaling overhead.

[0219] In this application, the event represents an event related to a terminal device initiated report (UE initiated report), or an event related to a terminal device initiated measurement result report, or an event related to a terminal device initiated report (or measurement result) after active measurement, or a specific condition related to a terminal device initiated measurement result report. For example, the terminal device can actively perform measurement (such as beam measurement, or channel measurement, etc.), and then obtain a measurement result related to the event. For another example, the terminal device can perform measurement based on a reference signal according to the configuration of the reference signal resource, and then obtain a measurement result related to the event. For another example, the terminal device actively measures, and reports a measurement result related to the event when a specific condition is met. For another example, the terminal device measures a reference signal related to the event to obtain a measurement result, and then the terminal device determines whether to report the measurement result to the network device according to the measurement result. The terminal device can determine whether a specific condition is met or whether the event occurs, and if so, the terminal device reports the corresponding measurement result. The event can also be referred to as any of the following: a trigger event, a layer 1 (L1) trigger event, a channel state information (CSI) measurement report trigger event, a beam measurement report trigger event, an L1 CSI report trigger event, an L1 beam measurement report trigger event, etc. The naming of the event is not limited in the embodiments of this application. The report triggered by the event or the report can be referred to as any of the following: an event related report, an event triggered or UE initiated report, an event triggered or UE initiated beam report, an event triggered or UE initiated CSI report, an event triggered or UE initiated beam measurement result report, an event triggered or UE initiated interference measurement report, an interference measurement report, a CSI report, a beam measurement result report, etc.

[0220] In this application, optionally, the signal quality can be a reference signal received power (RSRP), a signal to interference plus noise ratio (SINR), a layer 1 reference signal received power (L1-RSRP), a layer 1 signal to interference plus noise ratio (L1-SINR), a synchronization signal reference signal received power (SS-RSRP), a channel state information reference signal received power (CSI-RSRP), a synchronization signal signal to interference plus noise ratio (SS-SINR), or a channel state information signal to interference plus noise ratio (CSI-SINR), without limitation in this application.

The new beam can also be referred to as: a TCI state, a new beam measurement resource, a reference signal resource, a second beam measurement resource, a second measurement resource, or a resource corresponding to the new beam, without limitation in this application.

[0222] In this application, the start of the timer means starting the countdown of the set time length, or means starting the timer from 0. The timer restart means resetting the time length and starting the countdown again, that is, starting the countdown from the initial value or starting the timer from 0. The timer timeout means that the countdown reaches the set time length, or the counted time length reaches the set time length. The counter is used to count and record the number of times an event occurs.

[0223] In this application, the event triggered reporting mode includes Mode A and Mode B. That is, the terminal device can report the measurement result through Mode A or Mode B. Mode A and Mode B are introduced below.

[0224] I. Mode A includes the following steps a to c.

[0225] Step a: The terminal device sends first uplink signaling to the network device.

[0246] The technical solutions of the present application will be described below in combination with specific embodiments. It should be noted that the following embodiments take the first device as a terminal device and the second device as a network device to introduce the technical solutions of the present application.

[0247] FIG. 8 is a schematic diagram of one embodiment of the beam measurement method of the present application. Please refer to FIG. 8, the method comprises:

[0248] 801, the terminal device measures a serving beam and / or at least one new beam to obtain a first measurement result, or the terminal device measures a first activated beam and / or at least one new beam to obtain a first measurement result.

[0249] The serving beam is a beam currently used by the terminal device and the network device for transmission.

[0250] In one possible implementation, the at least one new beam is a beam of the terminal device other than the serving beam, or in other words, the at least one new beam is a beam of the terminal device different from the serving beam. For example, the at least one new beam can be understood as a candidate beam of the terminal device. For example, the at least one new beam is a beam corresponding to a TCI state other than a TCI state indicated for the terminal device in the TCI states configured by the network device for the terminal device. For another example, the at least one new beam is a beam corresponding to a TCI state other than a TCI state indicated for the terminal device in the TCI states activated by the network device for the terminal device. The serving beam and the at least one new beam are configured by the network device for the terminal device for the same measurement reporting process or the same measurement reporting configuration. Therefore, the at least one new beam is referred to as at least one new beam corresponding to the serving beam. The terminal device measures the serving beam and the at least one new beam. The resource type corresponding to the serving beam is the same as the resource type corresponding to the at least one new beam. For example, the resource corresponding to the serving beam is an SSB resource, and the resource corresponding to the at least one new beam is an SSB resource. For another example, the resource corresponding to the serving beam is a CSI-RS resource, and the resource corresponding to the at least one new beam is a CSI-RS resource.

[0251] In another possible implementation, the at least one new beam is a beam of the terminal device other than the first activated beam. Or in other words, the at least one new beam is a beam of the terminal device different from the first activated beam. For example, the at least one new beam can be a beam other than the first activated beam activated by the network device for the terminal device. Optionally, the first activated beam can or can not be the serving beam of the terminal device. When the network device indicates the first activated beam as the serving beam of the terminal device, the first activated beam is the serving beam.

[0252] It should be noted that if the terminal device transmits with multiple TRPs, the terminal device includes multiple serving beams, and the multiple serving beams correspond to the multiple TRPs in a one-to-one manner.

[0253] Optionally, the terminal device measures the serving beams, and the first measurement result includes a measurement result of the serving beams. For example, the first measurement result includes at least one of the following: a signal quality of the serving beams, or an index of the serving beams.

[0254] Optionally, the terminal device measures the serving beams and the at least one new beam, and the first measurement result includes a measurement result of the serving beams and a measurement result of the at least one new beam. For example, the first measurement result includes at least one of the following: a signal quality of the serving beams, a signal quality of the at least one new beam, a signal quality difference between the at least one new beam and the serving beams, an index of the serving beams, or an index of the at least one new beam.

[0255] It should be noted that, optionally, the resources corresponding to the serving beams and the resources corresponding to the at least one new beam can belong to the same resource set. The resource set can be referred to as a new beam resource set or a beam resource set, and the specific application is not limited. Alternatively, the resources corresponding to the serving beams and the resources corresponding to the at least one new beam can belong to different resource sets.

[0256] Optionally, the embodiment shown in FIG. 8 further includes step 801a, which can be performed before step 801.

[0257] 801a. The terminal device sends capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.

[0258] The capability information includes at least one of the following: whether the terminal device supports triggering the measurement result reporting of the beams, or a reporting mode supported by the terminal device. The reporting mode includes a first mode and a second mode. The first mode includes: when the number of times that an event occurs within a preset time is greater than or equal to a second threshold value, triggering the measurement result reporting. The second mode includes: when an event occurs, triggering the measurement result reporting. The preset time can be configured by the network device for the terminal device, or reported by the terminal device, or specified by a communication protocol, and the specific application is not limited. The second threshold value can be configured by the network device for the terminal device, or reported by the terminal device, or specified by a communication protocol, and the specific application is not limited.

[0259] Specifically, the terminal device can report the reporting mode supported by the terminal device through the capability information of the terminal device. For example, the terminal device can report which one of the mode one and the mode two is supported by the terminal device through a terminal capability parameter. Alternatively, the terminal device can report whether the mode one is supported by the terminal device through a terminal capability parameter. Alternatively, the terminal device can report whether the mode two is supported by the terminal device through a terminal capability parameter. Alternatively, as long as the terminal device supports the reporting of the measurement result of the beam, it is indicated that the terminal device supports the first mode by default, and there is no need to additionally report the reporting mode supported by the terminal device. Alternatively, as long as the terminal device supports the reporting of the measurement result of the beam, it is indicated that the terminal device supports the second mode by default, and there is no need to additionally report the reporting mode supported by the terminal device.

[0260] Optionally, the capability information can further include one or more of the following: a first threshold value, a value range of the first threshold value, a second threshold value, a value range of the second threshold value, a third threshold value, a value range of the third threshold value, a fourth threshold value, a value range of the fourth threshold value, a fifth threshold value, a value range of the fifth threshold value, a sixth threshold value, a value range of the sixth threshold value, a timing duration of a first timer, a value range of the timing duration of the first timer, a timing duration of a second timer, a value range of the timing duration of the second timer, a timing duration of a third timer, a value range of the timing duration of the third timer, a number of second timers that can be maintained by the terminal device, a number of second counters that can be maintained by the terminal device, a number of third timers that can be maintained by the terminal device, or a number of third counters that can be maintained by the terminal device. The first threshold value to the sixth threshold value, the first timer, the second timer, the third timer, the first counter, the second counter and the third counter can be referred to the relevant description in the following.

[0261] Optionally, the network device can configure the terminal device to report the measurement result in the first mode or the second mode. If the network device configures the terminal device to report the measurement result in the first mode, the terminal device reports the measurement result in the first mode. If the network device configures the terminal device to report the measurement result in the second mode, the terminal device reports the measurement result in the second mode. Alternatively, the network device does not need to configure the terminal device to report the measurement result in the first mode or the second mode. If the terminal device supports the first mode, the terminal device reports the measurement result in the first mode. If the terminal device does not support the first mode (for example, the terminal device supports the second mode), the terminal device reports the measurement result in the second mode. In other words, the terminal device reports the measurement result in the first mode can mean that the terminal device supports the first mode. Alternatively, the terminal device reports the measurement result in the first mode can mean that the network device configures the terminal device to report the measurement result in the first mode. The terminal device reports the measurement result in the second mode can mean that the terminal device only supports the second mode. Alternatively, the terminal device reports the measurement result in the second mode can mean that the network device configures the terminal device to report the measurement result in the second mode.

[0262] Optionally, the embodiment shown in FIG. 8 further includes step 801b. Step 801b can be performed before step 801.

[0263] 801b, the network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0264] The first configuration information is used to configure one or more events for the terminal device.

[0265] Optionally, the one or more events include at least one of the following: a first event, a second event, or a third event. The first event is that the signal quality of the serving beam is less than a first threshold value, or the first event is that the signal quality of the serving beam is less than or equal to the first threshold value. The second event is that the signal quality of one or more new beams is higher than the signal quality of the serving beam by a fourth threshold value, or the second event is that the difference between the signal quality of the one or more new beams and the signal quality of the serving beam is greater than the fourth threshold value, or the second event is that the difference between the signal quality of the one or more new beams and the signal quality of the serving beam is greater than or equal to the fourth threshold value. The third event is that the signal quality of the one or more new beams is higher than the signal quality of the first active beam by a sixth threshold value, or the third event is that the difference between the signal quality of the one or more new beams and the signal quality of the first active beam is greater than the sixth threshold value, or the third event is that the difference between the signal quality of the one or more new beams and the signal quality of the first active beam is greater than or equal to the sixth threshold value.

[0266] Optionally, the serving beam is a beam corresponding to a TCI state indicated by the network device for the terminal device, or the serving beam is a beam corresponding to a QCL resource in the TCI state indicated by the network device for the terminal device, or the serving beam is a beam corresponding to an SSB resource corresponding to the QCL resource in the TCI state indicated by the network device for the terminal device. The at least one new beam refers to a beam other than the serving beam. The at least one new beam can be a beam corresponding to a new beam measurement resource configured by the network device for the terminal device. Alternatively, the at least one new beam is a beam corresponding to a TCI state other than the TCI state indicated by the network device for the terminal device in the TCI state configured or activated by the network device for the terminal device.

[0267] The SSB resource corresponding to the QCL resource in the TCI state indicated by the network device for the terminal device can be understood as an SSB resource having a QCL relationship with the QCL resource. For example, the SSB resource is a source QCL resource in a QCL chain, and the source QCL resource is an SSB resource. The QCL chain is determined according to the QCL resource in the TCI state indicated by the network device for the terminal device. For example, the QCL resource in the TCI state indicated by the network device for the terminal device is a CSI-RS resource. The QCL resource in the TCI state corresponding to the CSI-RS resource is a tracking reference signal (TRS) resource. The TCI state corresponding to the CSI-RS resource can be understood as a TCI state adopted by the network device for transmitting the CSI-RS resource, or a TCI state adopted by the network device for transmitting a CSI-RS corresponding to the CSI-RS. And the QCL resource in the TCI state corresponding to the TRS resource is an SSB resource. The TCI state corresponding to the TRS resource can be understood as a TCI state adopted by the network device for transmitting the TRS resource, or a TCI state adopted by the network device for transmitting a TRS corresponding to the TRS. Therefore, the QCL resource in the TCI state indicated by the network device for the terminal device (such as the CSI-RS resource), the QCL resource in the TCI state corresponding to the CSI-RS resource (such as the TRS resource), and the QCL resource in the TCI state corresponding to the TRS resource (such as the SSB resource) form a QCL chain. The source QCL resource of the QCL chain is the SSB resource. That is, the SSB resource associated with the QCL resource in the TCI state indicated by the network device for the terminal device.

[0268] Optionally, the first active beam is a beam with the best signal quality among the currently active beams of the terminal device, or a beam with the worst signal quality among the currently active beams of the terminal device. Alternatively, the first active beam is the first beam among the currently active beams of the terminal device, or the last beam among the currently active beams of the terminal device. The at least one new beam is a beam other than the first active beam in the beam corresponding to the TCI state activated by the network device for the terminal device.

[0269] The first threshold value, the fourth threshold value, and the sixth threshold value can be configured by the network device for the terminal device, reported by the terminal device, or specified by a communication protocol, and the specific embodiments are not limited herein.

[0270] Optionally, if the embodiment shown in FIG. 8 includes step 801a, step 801b can be performed before step 801a.

[0271] Optionally, the network device configures the measurement configuration parameter for the terminal device, and the measurement configuration parameter includes one or more report configurations. Each report configuration is associated with one or more resource configurations. Each resource configuration can include a channel measurement resource or an interference measurement resource, the channel measurement resource being used for channel measurement, and the interference measurement resource being used for interference measurement. Each resource configuration includes one or more resource sets, wherein the resource set configured in the resource configuration for channel measurement is a resource set for channel measurement, and the resource set configured in the resource configuration for interference measurement is a resource set for interference measurement. Each resource set includes one or more resources.

[0272] Each report configuration can also be associated with one or more events. When any one of the one or more events occurs, the terminal device can report the measurement result associated with the event through the report configuration.

[0273] It should be noted that, optionally, the configuration parameters corresponding to one measurement reporting process can be through one report configuration and the resource configuration associated with the report configuration. The report configuration includes relevant parameters required for measurement result calculation and reporting. The resource configuration includes information of the reference signal resource to be measured.

[0274] Optionally, the first configuration information can further configure one or more of the following: the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value, the timing duration of the first timer, or the timing duration of the second timer. For the first threshold value to the fifth threshold value, the first timer, and the second timer, please refer to the relevant introduction in the following.

[0275] 802. The terminal device determines whether to trigger reporting of the measurement result according to the first measurement result.

[0276] The measurement result is part or all of the first measurement result.

[0277] Alternatively, the step 802 can be described as: the terminal device determines whether to report the measurement result according to the first measurement result, the measurement result being part or all of the first measurement result; or the terminal device determines whether to trigger sending of the first uplink signaling or the third uplink signaling according to the first measurement result, or the terminal device determines whether to send the first uplink signaling or the third uplink signaling according to the first measurement result. For the first uplink signaling and the third uplink signaling, refer to the foregoing description.

[0278] In a possible implementation, the network device configures a first event for the terminal device, and the first measurement result includes information of a serving beam. For example, the first measurement result includes at least one of the following: signal quality of the serving beam, or an index of the serving beam. The terminal device determines whether the first event occurs according to the first measurement result, and when the first event occurs, the terminal device determines whether to trigger reporting of the measurement result according to a corresponding rule. For specific processes, refer to the related description in the embodiments shown in FIGS. 9-12.

[0279] In another possible implementation, the network device configures a second event for the terminal device, and the first measurement result includes information of a serving beam and information of at least one new beam. For example, the first measurement result includes at least one of the following: signal quality of the serving beam, an index of the serving beam, signal quality of the at least one new beam, an index of the at least one new beam, or a signal quality difference between the at least one new beam and the serving beam. The terminal device determines whether the second event occurs according to the first measurement result, and when the second event occurs, the terminal device determines whether to trigger reporting of the measurement result according to a corresponding rule. For specific processes, refer to the related description in the embodiments shown in FIGS. 13-16.

[0280] In still another possible implementation, the network device configures a third event for the terminal device, and the first measurement result includes information of a first active beam and information of at least one new beam. For example, the first measurement result includes at least one of the following: signal quality of the first active beam, an index of the first active beam, signal quality of the at least one new beam, an index of the at least one new beam, or a signal quality difference between the at least one new beam and the first active beam. The terminal device determines whether the third event occurs according to the first measurement result, and when the third event occurs, the terminal device determines whether to trigger reporting of the measurement result according to a corresponding rule. For specific processes, refer to the related description in the embodiments shown in FIGS. 17-20.

[0281] In the embodiments of the present application, the terminal device measures the serving beam and / or at least one new beam to obtain a first measurement result. The at least one new beam is a beam of the terminal device other than the serving beam. Then, the terminal device determines whether to trigger the measurement result reporting according to the first measurement result. Thus, the terminal device measures different types of beams. This facilitates the terminal device to determine whether to trigger the measurement result reporting or to select whether to report the measurement result in combination with the measurement results of different types of beams. This avoids the terminal device from reporting unnecessary measurement results and saves signaling overhead.

[0282] FIG. 9 is a schematic diagram of another embodiment of the beam measurement method according to the present application. Referring to FIG. 9, the method comprises the following steps:

[0283] 901. The terminal device measures the serving beam to obtain a first measurement result.

[0284] Step 901 is similar to step 801 in the embodiment shown in FIG. 8, and details can be referred to the related description of step 801 in the embodiment shown in FIG. 8, which will not be repeated here.

[0285] 902. If the first measurement result indicates that a first event occurs, the terminal device performs an operation on a first timer and / or performs an operation on a first counter.

[0286] The first timer is a timer corresponding to the serving beam, and the first timer is a timer started when or after the first event occurs. The first timer is used to set a time period for recording the number of occurrences of the first event. During the running of the first timer, the terminal device records the number of occurrences of the first event. The first counter is a counter corresponding to the serving beam, and the first counter is used to record the number of occurrences of the first event, or in other words, to record the number of occurrences of the first event during the running of the first timer. For example, the first measurement result includes the signal quality of the serving beam, and if the signal quality of the serving beam is less than a first threshold value, it indicates that the first event occurs. Then the terminal device performs an operation on the first timer and / or performs an operation on the first counter.

[0287] It should be noted that when the terminal device includes multiple serving beams, each serving beam can correspond to a first timer and a first counter, and different serving beams correspond to different first timers and different first counters. Of course, multiple serving beams can also correspond to the same first timer and the same first counter, which is not limited in the present application.

[0288] Optionally, the operation of the terminal device on the first timer includes starting or restarting the first timer, and the operation of the terminal device on the first counter includes increasing the value of the first counter by one.

[0289] Specifically, if the first timer is not running, the terminal device starts the first timer and increments the first counter by one. If the first timer is running, the terminal device restarts the first timer and increments the first counter by one. Alternatively, if the first timer is running, the terminal device can only increment the first counter by one without restarting the first timer.

[0290] In one example, when the first event occurs, if the value of the first counter is 0 and the first timer is not running, the terminal device starts the first timer and increments the value of the first counter by one. For example, the value of the first counter is 0 and the first timer is not running. When the first event occurs, the terminal device starts the first timer (i.e. the first timer starts running), and the terminal device increments the value of the first counter by one (i.e. the value recorded by the first counter is updated to 1).

[0291] In another example, when the first event occurs, if the value of the first counter is greater than 0 and the first timer is not running, the terminal device starts the first timer and increments the value of the first counter by one. For example, the value of the first counter is 1 and the first timer is not running. When the first event occurs, the terminal device starts the first timer (i.e. the first timer starts running), and the terminal device increments the value of the first counter by one (i.e. the value recorded by the first counter is updated to 2).

[0292] In another example, when the first event occurs, if the value of the first counter is greater than 0 and the first timer is running, the terminal device restarts the first timer and increments the value of the first counter by one. For example, the value of the first counter is 1 and the first timer is running. When the first event occurs, the terminal device restarts the first timer (i.e. the first timer starts running), and the terminal device increments the value of the first counter by one (i.e. the value recorded by the first counter is updated to 2).

[0293] In another example, when the first event occurs, if the value of the first counter is greater than 0 and the first timer is running, the terminal device does not restart the first timer and increments the value of the first counter by one. For example, the value of the first counter is 1 and the first timer is running. When the first event occurs, the first timer continues running, and the terminal device increments the value of the first counter by one (i.e. the value recorded by the first counter is updated to 2).

[0294] In one possible implementation, before step 902 of the embodiment shown in FIG. 9, there is further included step 1001 in the embodiment shown in FIG. 10. Step 1001 can be performed after step 901 and before step 902.

[0295] 1001、The physical layer of the terminal device sends the first indication information to the MAC layer of the terminal device. Correspondingly, the MAC layer of the terminal device receives the first indication information from the physical layer of the terminal device.

[0296] The first indication information is used to indicate occurrence of the first event.

[0297] Optionally, the first indication information is also used to indicate at least one of the following: an event index corresponding to the first event, an event type corresponding to the first event, or information of a serving beam. The information of the serving beam includes at least one of the following: an index of the serving beam, a signal quality of the serving beam, or a difference between the signal quality of the serving beam and a first threshold value. In this implementation manner, the step 902 specifically includes: if the first measurement result represents occurrence of the first event, the MAC layer of the terminal device performs the above-mentioned operation on the first timer, and / or the MAC layer of the terminal device performs the above-mentioned operation on the first counter. In this implementation manner, the terminal device adopts a cross-layer design, that is, the physical layer and the MAC layer of the terminal device jointly determine whether to trigger the measurement result reporting.

[0298] In another possible implementation manner, the terminal device adopts a non-cross-layer design, that is, the physical layer of the terminal device determines whether to trigger the measurement result. That is, the step 902 is an operation performed by the physical layer of the terminal device. That is, the physical layer of the terminal device performs the operation on the first timer, and / or the physical layer of the terminal device performs the above-mentioned operation on the first counter.

[0299] Optionally, if the first condition is met and the first measurement result represents occurrence of the first event, the terminal device performs the operation on the first timer, and / or the terminal device performs the operation on the first counter.

[0300] The first condition comprises at least one of the following: the terminal device reporting that the terminal device supports reporting of measurement results triggered by a state based on a timer and / or a state based on a counter, the terminal device reporting that the terminal device supports reporting of measurement results based on a state based on a timer and / or a state based on a counter, the network device configuring the terminal device to report measurement results triggered by a state based on a timer and / or a state based on a counter, the network device configuring the terminal device to report measurement results based on a state based on a timer and / or a state based on a counter, the terminal device supporting reporting of measurement results in a first mode, or the network device configuring the terminal device to report measurement results in the first mode. The first mode comprises: when the number of occurrences of a first event within a preset time is greater than or equal to a second threshold value, the terminal device triggering reporting of measurement results. Alternatively, the first mode comprises: when the number of occurrences of the first event within the preset time is greater than or equal to the second threshold value, the first device reporting measurement results, or the first device sending measurement results corresponding to the first event, or the first device triggering sending of a first uplink signaling or a third uplink signaling, or the first device sending the first uplink signaling or the third uplink signaling. The first uplink signaling and the third uplink signaling can be referred to the foregoing description.

[0301] If the first condition is not met, when the first measurement result indicates that the first event occurs, the physical layer of the terminal device or the MAC layer of the terminal device directly triggers reporting of measurement results, without performing the foregoing operation on the first timer and / or the first counter.

[0302] 903、The terminal device determines whether to trigger reporting of measurement results according to the state of the first timer and / or the state of the first counter.

[0303] Specifically, if the value of the first counter is greater than or equal to a third threshold value before the first timer expires, the terminal device triggers reporting of measurement results. Alternatively, if the value of the first counter is greater than the third threshold value before the first timer expires, the terminal device triggers reporting of measurement results.

[0304] Alternatively, the determining whether to trigger the measurement result reporting by the terminal device according to the state of the first timer and / or the state of the first counter can be replaced by: determining whether to report the measurement result by the terminal device according to the state of the first timer and / or the state of the first counter, or determining whether to trigger the sending of the first uplink signaling or determining whether to send the first uplink signaling by the terminal device according to the state of the first timer and / or the state of the first counter, or determining whether to trigger the sending of the third uplink signaling or determining whether to send the third uplink signaling by the terminal device according to the state of the first timer and / or the state of the first counter, or determining whether to trigger the measurement result reporting corresponding to the first event by the terminal device according to the state of the first timer and / or the state of the first counter, or determining whether to report the measurement result corresponding to the first event by the terminal device according to the state of the first timer and / or the state of the first counter.

[0305] Alternatively, in the case where the first condition is satisfied, if the value of the first counter is greater than or equal to the third threshold value before the first timer expires, the terminal device triggers the measurement result reporting, or the terminal device reports the measurement result corresponding to the first event, or the terminal device triggers the sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling. Alternatively, in the case where the first condition is satisfied, if the value of the first counter is greater than the third threshold value before the first timer expires, the terminal device triggers the measurement result reporting. If the first condition is not satisfied, when the first measurement result indicates that the first event occurs, the physical layer of the terminal device or the MAC layer of the terminal device directly triggers the measurement result reporting, and it is not necessary to determine whether to trigger the measurement result reporting according to the state of the first timer and / or the state of the first counter.

[0306] In a possible implementation, the terminal device judges whether to trigger the measurement result reporting according to the state of the first timer and / or the state of the first counter regardless of whether the first condition is met. The difference lies in that, if the first condition is met, the third threshold value can be an integer greater than or equal to 1. Optionally, the third threshold value is a positive integer configured by the network device for the terminal device. If the first condition is not met, the third threshold value is 1 by default. Of course, the third threshold value can also be configured by the network device for the terminal device, but the third threshold value can only be configured as 1. For the first condition, refer to the foregoing relevant description. In other words, if the fourth condition is met, the third threshold value is 1. The fourth condition includes at least one of the following: the terminal device reports that the terminal device supports reporting the measurement result in the second mode, or the network device configures the terminal device to report the measurement result in the second mode. The second mode includes that the terminal device triggers the measurement result reporting when an event occurs. In other words, the second mode includes that the terminal device triggers the measurement result reporting when the first event occurs, or the terminal device reports the measurement result corresponding to the first event, or the terminal device triggers the sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling.

[0307] If the terminal device reports the measurement result in the second mode, the third threshold value is 1. As long as the first event occurs once, the terminal device can trigger the measurement result reporting. In other words, the communication protocol stipulates that the third threshold value is 1 when the terminal device adopts the second mode; or the communication protocol stipulates that the network device configures the third threshold value to be 1 when the terminal device adopts the second mode.

[0308] For example, the terminal device adopts the cross-layer design to judge whether to trigger the measurement result reporting. In the step 903, the MAC layer of the terminal device judges whether to trigger the measurement result reporting according to the state of the first timer and / or the state of the first counter. Or, the MAC layer of the terminal device judges whether to report the measurement result according to the state of the first timer and / or the state of the first counter. Or, the MAC layer of the terminal device judges whether to trigger the measurement result corresponding to the first event according to the state of the first timer and / or the state of the first counter. Or, the MAC layer of the terminal device judges whether to trigger the sending of the first uplink signaling or the third uplink signaling according to the state of the first timer and / or the state of the first counter. Or, the MAC layer of the terminal device judges whether to send the first uplink signaling or the third uplink signaling according to the state of the first timer and / or the state of the first counter.

[0309] For another example, the terminal device determines whether to trigger the measurement result reporting by using a non-cross-layer design. In step 903, the physical layer of the terminal device determines whether to trigger the measurement result reporting according to the state of the first timer and / or the state of the first counter. Alternatively, the physical layer of the terminal device determines whether to report the measurement result according to the state of the first timer and / or the state of the first counter. Alternatively, the physical layer of the terminal device determines whether to trigger the measurement result corresponding to the first event according to the state of the first timer and / or the state of the first counter. Alternatively, the physical layer of the terminal device determines whether to trigger the sending of the first uplink signaling or the third uplink signaling according to the state of the first timer and / or the state of the first counter. Alternatively, the physical layer of the terminal device determines whether to send the first uplink signaling or the third uplink signaling according to the state of the first timer and / or the state of the first counter.

[0310] Optionally, when the terminal device triggers the measurement result reporting, the embodiment shown in FIG. 9 further includes step 904. Step 904 can be performed after step 903.

[0311] 904. The terminal device sends the measurement result associated with the first event to the network device. Correspondingly, the network device receives the measurement result associated with the first event from the terminal device.

[0312] Optionally, the measurement result associated with the first event includes the information of the serving beam. The information of the serving beam is described above. The measurement result associated with the first event can include part or all of the measurement result in the first measurement result. For example, the first measurement result includes the signal quality of the serving beam and the index of the serving beam. The measurement result associated with the first event includes the signal quality of the serving beam.

[0313] Two possible implementation manners of the terminal device reporting the measurement result associated with the first event are described below.

[0314] Implementation manner one: The terminal device sends the first uplink signaling to the network device, and the first uplink signaling is used to request the network device to schedule the uplink resource. Optionally, the first uplink signaling is a PUCCH signal or a scheduling request (SR) signal. Then, the network device sends the first DCI to the terminal device, and the first DCI is used to schedule the first uplink resource. The terminal device sends the second uplink signaling to the network device through the first uplink resource, and the second uplink signaling includes the measurement result associated with the first event.

[0315] In a second implementation, the terminal device sends third uplink signaling to the network device, and the third uplink signaling is used to inform the network device that the terminal device reports the measurement result on the fourth uplink signaling associated with the third uplink signaling. Optionally, the third uplink signaling is a PUCCH signal or an SR signal. Then, the terminal device sends the fourth uplink signaling to the network device, and the fourth uplink signaling includes the measurement result associated with the first event.

[0316] Optionally, the embodiment shown in FIG. 9 further includes step 905. Step 905 can be performed after step 904.

[0317] 905、The terminal device closes the first timer, and / or the terminal device sets the first counter to 0.

[0318] Specifically, after the terminal device reports the measurement result associated with the first event, the terminal device closes or stops the first timer, and when the terminal device starts the first timer next time, the terminal device restarts the countdown, and / or the terminal device sets the first counter to 0.

[0319] In combination with the first implementation of the measurement result reporting shown in step 904, after the terminal device reports the measurement result associated with the first event, it can mean that after the terminal device completes the sending of the first uplink signaling, or after the terminal device receives the DCI from the network device, or after the terminal device completes the sending of the second uplink signaling, or after the terminal device receives the response message of the second uplink signaling from the network device.

[0320] In combination with the second implementation of the measurement result reporting shown in step 904, after the terminal device reports the measurement result associated with the first event, it can mean that after the terminal device completes the sending of the third uplink signaling, or after the terminal device receives the response message of the third uplink signaling from the network device, or after the terminal device completes the sending of the fourth uplink signaling, or after the terminal device receives the response message of the fourth uplink signaling from the network device.

[0321] Optionally, the embodiment shown in FIG. 9 further includes step 906, which can be performed after step 903.

[0322] 906、After the first timer expires, the terminal device sets the first counter to 0.

[0323] Thus, it is convenient to restart counting the occurrence of the first event.

[0324] Optionally, the embodiment shown in FIG. 9 further includes step 907. Step 907 can be performed after step 903.

[0325] 907、When the service beam changes, the terminal device closes the first timer, and / or the terminal device sets the first counter to 0.

[0326] In a possible implementation, for a cell, the service beam of the terminal device changes can mean that the currently effective TCI state of the cell changes. For example, the network device indicates a new TCI state for the terminal device. Alternatively, the service beam of the terminal device changes can mean that the QCL resource in the currently effective TCI state of the cell changes. Alternatively, the service beam of the terminal device changes can mean that the reference signal corresponding to the QCL resource associated with the QCL resource in the currently effective TCI state of the cell changes. In this case, the terminal device closes the first timer, and / or the terminal device sets the first counter to 0.

[0327] In another possible implementation, for a measurement reporting configuration, when the service beam changes, the network device updates the service beam measurement resource corresponding to the reporting configuration. In this case, the terminal device closes the first timer, and / or the terminal device sets the first counter to 0.

[0328] In the embodiments of the present application, the terminal device measures the service beam to obtain a first measurement result. If the first measurement result indicates that a first event occurs, the terminal device performs an operation on a first timer, and / or performs an operation on a first counter. The first timer is a timer corresponding to the service beam, and the first counter is a counter corresponding to the service beam. The terminal device determines whether to trigger measurement result reporting according to the state of the first timer and / or the state of the first counter. As can be seen, the terminal device monitors whether the first event occurs through the first measurement result, when the first event occurs, the terminal device performs an operation on the first timer, and / or performs an operation on the first counter, and determines whether to trigger measurement result reporting according to the state of the first timer and / or the state of the first counter. Thus, the terminal device reasonably reports the measurement result. Avoids the terminal device from reporting unnecessary measurement results, and saves signaling overhead.

[0329] In the present application, when the terminal device adopts the second mode, for the case where the first event occurs, the terminal device can also determine whether to trigger measurement result reporting through other manners. The following two possible implementation manners are introduced in combination with the embodiments shown in FIG. 11 and FIG. 12. The present application is still applicable to other implementation manners, and the present application is not limited in particular.

[0330] FIG. 11 is a schematic diagram of another embodiment of the beam measurement method according to an embodiment of the present application. Please refer to FIG. 11, the method comprises:

[0331] 1101, the terminal device measures the service beam to obtain a first measurement result.

[0332] Step 1101 is similar to step 801 in the foregoing embodiment of FIG. 8, and details can be referred to the related description of step 801 in the foregoing embodiment of FIG. 8, which will not be repeated here.

[0333] 1102. If the first measurement result represents occurrence of the first event, the terminal device triggers reporting of the measurement result.

[0334] For example, the first measurement result includes signal quality of a serving beam. If the signal quality of the serving beam is less than a first threshold value, it indicates occurrence of the first event, and then the terminal device triggers reporting of the measurement result.

[0335] Optionally, the above step 1102 can be alternatively described as: if the first measurement result represents occurrence of the first event, the terminal device reports the measurement result corresponding to the first event; or if the first measurement result represents occurrence of the first event, the terminal device triggers sending of the first uplink signaling or the third uplink signaling; or if the first measurement result represents occurrence of the first event, the terminal device sends the first uplink signaling or the third uplink signaling.

[0336] Optionally, if the first condition is not met, and the first measurement result represents occurrence of the first event, the terminal device triggers reporting of the measurement result, or the terminal device reports the measurement result corresponding to the first event, or the terminal device triggers sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling. The first condition is described above, and details will not be repeated here. In other words, if the fourth condition is met, and the first measurement result represents occurrence of the first event, the terminal device triggers reporting of the measurement result, or the terminal device reports the measurement result corresponding to the first event, or the terminal device triggers sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling. The fourth condition is described above, and details will not be repeated here.

[0337] 1103. The terminal device sends the measurement result associated with the first event to the network device. Correspondingly, the network device receives the measurement result associated with the first event from the terminal device.

[0338] Step 1103 is similar to step 904 in the foregoing embodiment of FIG. 9, and details can be referred to the related description of step 904 in the foregoing embodiment of FIG. 9, which will not be repeated here.

[0339] In the embodiment, the terminal device measures the serving beam to obtain a first measurement result. If the first measurement result represents occurrence of a first event, the terminal device triggers reporting of the measurement result. As can be seen, the terminal device measures the serving beam, and if the first event occurs, the terminal device triggers reporting of the measurement result. Thus, the terminal device reports the measurement result associated with the first event when the first event occurs. Thus, unnecessary reporting of the measurement result by the terminal device is avoided, and signaling overhead is saved.

[0340] FIG. 12 is a schematic diagram of another embodiment of the beam measurement method according to the application. Referring to FIG. 12, the method comprises the following steps:

[0341] 1201. The physical layer of the terminal device measures the serving beam to obtain a first measurement result.

[0342] Step 1201 is similar to step 801 in the embodiment shown in FIG. 8, and details are referable to the related description of step 801 in the embodiment shown in FIG. 8, which will not be repeated here.

[0343] 1202. The physical layer of the terminal device sends first indication information to the MAC layer of the terminal device. Correspondingly, the MAC layer of the terminal device receives the first indication information from the physical layer of the terminal device.

[0344] The first indication information is similar to the first indication information in the embodiment shown in FIG. 10, and details are referable to the related description of the first indication information in the embodiment shown in FIG. 10, which will not be repeated here.

[0345] 1203. The MAC layer of the terminal device triggers reporting of the measurement result according to the first indication information.

[0346] It should be noted that in the embodiment, the terminal device adopts cross-layer design, that is, the physical layer and the MAC layer of the terminal device jointly determine whether to trigger reporting of the measurement result.

[0347] Optionally, the above step 1203 can be alternatively described as: the MAC layer of the terminal device triggers the physical layer of the terminal device to report the measurement result according to the first indication information. Or the MAC of the terminal device triggers the physical layer of the terminal device to report the measurement result corresponding to the first event according to the first indication information. Or the MAC layer of the terminal device triggers the physical layer of the terminal device to send the first uplink signaling or the third uplink signaling according to the first indication information.

[0348] Optionally, if the first condition is not met, and the MAC layer of the terminal device receives the first indication information sent by the physical layer of the terminal device, the MAC layer of the terminal device triggers the measurement result reporting, or the MAC layer of the terminal device triggers the physical layer of the terminal device to report the measurement result, or the MAC of the terminal device triggers the physical layer of the terminal device to report the measurement result corresponding to the first event, or the MAC layer of the terminal device triggers the physical layer of the terminal device to send the first uplink signaling or the third uplink signaling. The first condition is described above and will not be repeated here. In other words, if the fourth condition is met, and the MAC layer of the terminal device receives the first indication information sent by the physical layer of the terminal device, the MAC layer of the terminal device triggers the measurement result reporting, or the MAC layer of the terminal device triggers the physical layer of the terminal device to report the measurement result, or the MAC of the terminal device triggers the physical layer of the terminal device to report the measurement result corresponding to the first event, or the MAC layer of the terminal device triggers the physical layer of the terminal device to send the first uplink signaling or the third uplink signaling. The fourth condition is described above and will not be repeated here.

[0349] 1204、The MAC layer of the terminal device sends the measurement result associated with the first event to the network device. Correspondingly, the network device receives the measurement result associated with the first event from the MAC layer of the terminal device.

[0350] Step 1204 is similar to step 904 in the embodiment shown in FIG. 9, and details are described above with reference to step 904 in the embodiment shown in FIG. 9, which will not be repeated here.

[0351] In the embodiment, the terminal device measures the serving beam to obtain the first measurement result. The physical layer of the terminal device sends the first indication information to the MAC layer of the terminal device. The MAC layer of the terminal device triggers the measurement result reporting according to the first indication information. Therefore, the terminal device measures the serving beam, and when the first event occurs, the physical layer of the terminal device sends the first indication information to the MAC layer of the terminal device. The MAC layer of the terminal device triggers the measurement result reporting according to the first indication information. Thus, the terminal device reports the measurement result associated with the first event when the first event occurs. Therefore, unnecessary measurement results are avoided, and signaling overhead is saved.

[0352] FIG. 13 is another embodiment of the beam measurement method according to the present application. Please refer to FIG. 13, the method includes:

[0353] 1301、The terminal device measures the serving beam and at least one new beam to obtain the first measurement result.

[0354] Step 1301 is similar to step 801 in the foregoing embodiment shown in FIG. 8, and details can be referred to the related description of step 801 in the foregoing embodiment shown in FIG. 8, which will not be repeated here.

[0355] 1302. If the first measurement result represents occurrence of the second event, the terminal device performs an operation on a second timer corresponding to a new beam satisfying the occurrence condition of the second event, and / or performs an operation on a second counter corresponding to the new beam satisfying the occurrence condition of the second event.

[0356] The new beam satisfying the occurrence condition of the second event is one or more. The second event can be referred to the related description in the foregoing embodiment shown in FIG. 8. The new beam satisfying the occurrence condition of the second event refers to a new beam whose signal quality is higher than that of the serving beam by a fourth threshold value, or a new beam whose signal quality difference from the serving beam is greater than the fourth threshold value, or a new beam whose signal quality difference from the serving beam is greater than or equal to the fourth threshold value.

[0357] In a possible implementation, each new beam in the new beams satisfying the occurrence condition of the second event corresponds to a second timer and / or a second counter, and different new beams correspond to different second timers and / or different second counters. That is, the second timer and the second counter are both beam-level, and each new beam has an independent second timer and an independent second counter.

[0358] In another possible implementation, part or all of the new beams in the new beams satisfying the occurrence condition of the second event correspond to the same second timer and / or the same second counter. For example, all the new beams satisfying the occurrence condition of the second event correspond to the same second timer, and each new beam in the new beams satisfying the occurrence condition of the second event corresponds to a second counter, and different new beams correspond to different second counters. That is, all the new beams satisfying the occurrence condition of the second event share the same second timer, that is, the second timers corresponding to the new beams are the same. For another example, all the new beams satisfying the occurrence condition of the second event correspond to the same second counter, and each new beam in the new beams satisfying the occurrence condition of the second event corresponds to a second timer, and different new beams correspond to different second timers. That is, all the new beams satisfying the occurrence condition of the second event share the same second counter, that is, the second counters corresponding to the new beams are the same.

[0359] Hereinafter, the technical solutions of the present application will be mainly described by taking an example of each new beam corresponding to a second timer and a second counter.

[0360] Optionally, the terminal device performs an operation on a second timer corresponding to a new beam satisfying the occurrence condition of the second event, including: for any new beam satisfying the occurrence condition of the second event, the terminal device starts or restarts the second timer corresponding to the new beam. Alternatively, for a first new beam in the new beams satisfying the occurrence condition of the second event, the terminal device starts or restarts the second timer corresponding to the first new beam. Optionally, the terminal device performs an operation on a second counter corresponding to a new beam satisfying the occurrence condition of the second event, including: for any new beam satisfying the occurrence condition of the second event, the terminal device adds one to the value of the second counter corresponding to the new beam. Alternatively, for a first new beam in the new beams satisfying the occurrence condition of the second event, the terminal device adds one to the value of the second counter corresponding to the first new beam.

[0361] Specifically, for any new beam satisfying the occurrence condition of the second event, if the second timer corresponding to the new beam has not been started, the terminal device starts the second timer corresponding to the new beam and adds one to the value of the second counter corresponding to the new beam. If the second timer corresponding to the new beam has been started, the terminal device restarts the second timer corresponding to the new beam (i.e., starts timing from the initial value again) and adds one to the value of the second counter corresponding to the new beam. That is, the terminal device starts or restarts the second timer corresponding to the new beam and adds one to the value of the second counter corresponding to the new beam. Optionally, if the second timer corresponding to the new beam has been started, the terminal device can only add one to the value of the second counter corresponding to the new beam, and the terminal device does not restart the second timer corresponding to the new beam.

[0362] In an example, when the second event occurs, for a certain new beam satisfying the occurrence condition of the second event, if the value of the second counter corresponding to the new beam is 0 and the second timer corresponding to the new beam has not been started, the terminal device starts the second timer and adds one to the value of the second counter. For example, the value of the second counter corresponding to the new beam is 0 and the second timer corresponding to the new beam has not been started. In the case that the new beam satisfies the occurrence condition of the second event, the terminal device starts the second timer corresponding to the new beam (i.e., the second timer starts timing), and the terminal device adds one to the value of the second counter corresponding to the new beam (i.e., the value recorded by the second counter is updated to 1).

[0363] In another example, when the second event occurs, for a new beam that satisfies the occurrence condition of the second event, if the value of the second counter corresponding to the new beam is greater than 0 and the second timer corresponding to the new beam is not timing, the terminal device starts the second timer corresponding to the new beam, and adds 1 to the value of the second counter corresponding to the new beam. For example, the value of the second counter corresponding to the new beam is 1, and the second timer corresponding to the new beam is not timing. When the new beam satisfies the occurrence condition of the second event, the terminal device starts the second timer corresponding to the new beam (i.e., the second timer starts timing), and the terminal device adds 1 to the value of the second counter corresponding to the new beam (i.e., the value recorded by the second counter is updated to 2).

[0364] In another example, when the second event occurs, for a new beam that satisfies the occurrence condition of the second event, if the value of the second counter corresponding to the new beam is greater than 0 and the second timer corresponding to the new beam is timing, the terminal device restarts the second timer corresponding to the new beam, and adds 1 to the value of the second counter corresponding to the new beam. For example, the value of the second counter corresponding to the new beam is 1, and the second timer corresponding to the new beam is timing. When the new beam satisfies the occurrence condition of the second event, the terminal device restarts the second timer corresponding to the new beam (i.e., the second timer starts timing), and the terminal device adds 1 to the value of the second counter corresponding to the new beam (i.e., the value recorded by the second counter is updated to 2).

[0365] In another example, when the second event occurs, for a new beam that satisfies the occurrence condition of the second event, if the value of the second counter corresponding to the new beam is greater than 0 and the second timer corresponding to the new beam is timing, the terminal device adds 1 to the value of the second counter corresponding to the new beam. For example, the value of the second counter corresponding to the new beam is 1, and the second timer corresponding to the new beam is timing. When the new beam satisfies the occurrence condition of the second event, the second timer corresponding to the new beam continues to time, and the terminal device adds 1 to the value of the second counter corresponding to the new beam (i.e., the value recorded by the second counter is updated to 2).

[0366] In a possible implementation, before step 1302 of the embodiment shown in FIG. 13, step 1401 in the embodiment shown in FIG. 14 is further included. Step 1401 can be executed after step 1301 and before step 1302.

[0367] 1401, the physical layer of the terminal device sends the second indication information to the MAC layer of the terminal device. Correspondingly, the MAC layer of the terminal device receives the second indication information from the physical layer of the terminal device.

[0368] The second indication information is used for indicating occurrence of the second event.

[0369] Optionally, the second indication information is further used for indicating at least one of the following: an event index corresponding to the second event, an event type corresponding to the second event, information of a serving beam, or information of a new beam satisfying an occurrence condition of the second event. The information of the serving beam includes at least one of the following: an index of the serving beam, or a signal quality of the serving beam. The information of the new beam satisfying the occurrence condition of the second event includes at least one of the following: an index of the new beam satisfying the occurrence condition of the second event, a signal quality of the new beam satisfying the occurrence condition of the second event, or a signal quality difference between the new beam satisfying the occurrence condition of the second event and the serving beam. The above information can be indicated by other indication information, which is not limited in the present application.

[0370] In the implementation manner, the step 1302 specifically includes: if the first measurement result represents occurrence of the second event, the MAC layer of the terminal device performs the above operation on a second timer corresponding to the new beam satisfying the occurrence condition of the second event, and / or the MAC layer of the terminal device performs the above operation on a second counter corresponding to the new beam satisfying the occurrence condition of the second event. In the implementation manner, the terminal device adopts a cross-layer design, that is, the physical layer and the MAC layer of the terminal device jointly determine whether to trigger measurement result reporting.

[0371] In another possible implementation manner, the terminal device adopts a non-cross-layer design, that is, the physical layer of the terminal device determines whether to trigger measurement result reporting, or the physical layer of the terminal device determines whether to report the measurement result corresponding to the second event, or the physical layer of the terminal device determines whether to trigger sending of the first uplink signaling or the third uplink signaling, or the physical layer of the terminal device determines whether to send the first uplink signaling or the third uplink signaling. For the first uplink signaling and the third uplink signaling, refer to the foregoing relevant introduction. That is, the step 1302 is an operation performed by the physical layer of the terminal device. That is, the physical layer of the terminal device performs the above operation on a second timer corresponding to the new beam satisfying the occurrence condition of the second event, and / or the physical layer of the terminal device performs the above operation on a second counter corresponding to the new beam satisfying the occurrence condition of the second event.

[0372] Optionally, if the first condition is satisfied and the first measurement result represents occurrence of the second event, the terminal device performs an operation on a second timer corresponding to the new beam satisfying the occurrence condition of the second event, and / or the terminal device performs an operation on a second counter corresponding to the new beam satisfying the occurrence condition of the second event. The first condition is described in the foregoing step 902 in the embodiment shown in FIG. 9, which is not described herein again.

[0373] In the implementation, the terminal device reports the measurement result in the first mode, or the terminal device supports reporting the measurement result in the first mode.

[0374] 1303. The terminal device determines whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter.

[0375] Specifically, if there is at least one new beam satisfying the second condition in the new beams satisfying the occurrence condition of the second event, the terminal device triggers the measurement result reporting. The second condition includes that the value of the second counter corresponding to the at least one new beam is greater than or equal to a fifth threshold before the second timer corresponding to the at least one new beam expires. Alternatively, the second condition includes that the value of the second counter corresponding to the at least one new beam is greater than a fifth threshold before the second timer corresponding to the at least one new beam expires. For example, the new beams satisfying the occurrence condition of the second event include a first new beam, and the terminal device triggers the measurement result reporting when the value of the second counter corresponding to the first new beam is greater than or equal to the fifth threshold before the second timer corresponding to the first new beam expires.

[0376] Alternatively, the terminal device determines whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter can be described as that the terminal device determines whether to report the measurement result according to the state of the second timer and / or the state of the second counter, or the terminal device determines whether to trigger the sending of the first uplink signaling or determines whether to send the first uplink signaling according to the state of the second timer and / or the state of the second counter, or the terminal device determines whether to trigger the sending of the third uplink signaling or determines whether to send the third uplink signaling according to the state of the second timer and / or the state of the second counter, or the terminal device determines whether to trigger the measurement result reporting corresponding to the second event according to the state of the second timer and / or the state of the second counter, or the terminal device determines whether to report the measurement result corresponding to the second event according to the state of the second timer and / or the state of the second counter.

[0377] Alternatively, if there is at least one new beam satisfying the second condition in the new beams satisfying the occurrence condition of the second event when the first condition is satisfied, the terminal device triggers the measurement result reporting, or the terminal device reports the measurement result corresponding to the second event, or the terminal device triggers the sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling.

[0378] If the first condition is not satisfied, when the first measurement result represents that the second event occurs, the physical layer of the terminal device or the MAC layer of the terminal device directly triggers the measurement result reporting, and it is not necessary to determine whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter. Or, if the first condition is not satisfied, when the first measurement result represents that the second event occurs, the physical layer of the terminal device or the MAC layer of the terminal device directly triggers the measurement result reporting, and it is not necessary to determine whether to trigger the measurement result reporting according to the second condition.

[0379] In a possible implementation manner, whether the first condition is satisfied or not, the terminal device determines whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter. The difference lies in that, if the first condition is satisfied, the fifth threshold value can be an integer greater than or equal to 1. Optionally, the fifth threshold value is a positive integer configured by the network device for the terminal device. If the first condition is not satisfied, the fifth threshold value is 1 by default. Of course, the fifth threshold value can also be configured by the network device, but can only be configured as 1. For the first condition, refer to the foregoing relevant introduction. In other words, if the fourth condition is satisfied, the fifth threshold value is 1. For the fourth condition, refer to the foregoing relevant introduction.

[0380] In this implementation manner, the terminal device reports the measurement result in the second mode, or the terminal device supports reporting the measurement result in the second mode.

[0381] If the terminal device reports the measurement result in the second mode, the value of the fifth threshold value is 1. Once the second event occurs, the terminal device can trigger the measurement result reporting. Or, according to the communication protocol, when the terminal device adopts the second mode, the value of the fifth threshold value is 1; or, according to the communication protocol, when the terminal device adopts the second mode, the network device can only configure the value of the fifth threshold value as 1.

[0382] For example, the terminal device adopts a cross-layer design to determine whether to trigger the measurement result reporting. In the step 1303, the MAC layer of the terminal device determines whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter. Or, the MAC layer of the terminal device determines whether to report the measurement result corresponding to the second event according to the state of the second timer and / or the state of the second counter. Or, the MAC layer of the terminal device determines whether to trigger the sending of the first uplink signaling or the third uplink signaling according to the state of the second timer and / or the state of the second counter. Or, the MAC layer of the terminal device determines whether to send the first uplink signaling or the third uplink signaling according to the state of the second timer and / or the state of the second counter.

[0383] For another example, the terminal device determines whether to trigger the reporting of the measurement result by using a non-cross-layer design. In step 1303, the physical layer of the terminal device determines whether to trigger the reporting of the measurement result according to the state of the second timer and / or the state of the second counter. Alternatively, the physical layer of the terminal device determines whether to report the measurement result corresponding to the second event according to the state of the second timer and / or the state of the second counter. Alternatively, the physical layer of the terminal device determines whether to trigger the sending of the first uplink signaling or the third uplink signaling according to the state of the second timer and / or the state of the second counter. Alternatively, the physical layer of the terminal device determines whether to send the first uplink signaling or the third uplink signaling according to the state of the second timer and / or the state of the second counter.

[0384] Optionally, when the terminal device triggers the reporting of the measurement result, the embodiment shown in FIG. 13 further includes step 1304. Step 1304 can be performed after step 1303.

[0385] 1304. The terminal device sends the measurement result associated with the second event to the network device. Correspondingly, the network device receives the measurement result associated with the second event from the terminal device.

[0386] The measurement result associated with the second event includes the information of the serving beam and / or the information of the new beam satisfying the occurrence condition of the second event. The information of the serving beam and the information of the new beam satisfying the occurrence condition of the second event are described above, and will not be repeated here. The measurement result associated with the second event can include part or all of the measurement result in the first measurement result. For example, the first measurement result includes the signal quality of the serving beam, the signal quality of the first new beam, and the signal quality of the second new beam. The first new beam satisfies the occurrence condition of the second event, and the second new beam does not satisfy the occurrence condition of the second event. The measurement result associated with the second event can include the signal quality of the serving beam and the signal quality of the first new beam.

[0387] Two possible implementation manners of the terminal device reporting the measurement result associated with the second event are described below.

[0388] Implementation manner one: the terminal device sends the first uplink signaling to the network device, and the first uplink signaling is used to request the network device to schedule the uplink resource. Then, the network device sends the first DCI to the terminal device, and the first DCI is used to schedule the first uplink resource. The terminal device sends the second uplink signaling to the network device through the first uplink resource. The second uplink signaling includes the measurement result associated with the second event. Optionally, the second uplink signaling is a PUCCH signal or an SR signal.

[0389] In a second implementation, the terminal device sends third uplink signaling to the network device. The third uplink signaling is used to inform the network device that the terminal device reports the measurement result on the fourth uplink signaling associated with the third uplink signaling. Optionally, the third uplink signaling is a PUCCH signal or an SR signal. Then, the terminal device sends the fourth uplink signaling to the network device, and the fourth uplink signaling includes the measurement result associated with the second event.

[0390] Optionally, after the terminal device reports the measurement result, the embodiment shown in FIG. 13 further includes step 1305, which can be performed after step 1304.

[0391] 1305. For any new beam satisfying the occurrence condition of the second event, the terminal device closes the second timer corresponding to part or all of the new beams satisfying the occurrence condition of the second event, and / or the terminal device sets the second counter corresponding to part or all of the new beams satisfying the occurrence condition of the second event to 0.

[0392] Specifically, after the terminal device reports the measurement result associated with the second event, the terminal device closes or stops the second timer corresponding to part or all of the new beams satisfying the occurrence condition of the second event, and / or the terminal device sets the second counter corresponding to part or all of the new beams satisfying the occurrence condition of the second event to 0.

[0393] Optionally, after the terminal device completes the reporting of the measurement result associated with the second event, a fourth timer can be started. During the counting period of the fourth timer (i.e., before the fourth timer expires), the terminal device is prohibited from triggering the reporting of the measurement result, or is static in reporting the same content, or is static in reporting the measurement result corresponding to the same beam, or is prohibited from reporting the measurement result corresponding to the beam that has been reported this time, so as to avoid wasting uplink resources. The fourth timer can be beam-level, i.e., for each beam reported by the terminal device, a fourth timer is started, and during the counting period of the fourth timer (i.e., before the fourth timer expires), the terminal device is prohibited from reporting the information of the beam. Alternatively, for each beam that meets the triggering reporting condition, a fourth timer is started, and during the counting period of the fourth timer (i.e., before the fourth timer expires), the terminal device is prohibited from reporting the information of the beam. Alternatively, for each beam that meets the triggering reporting condition, a fourth timer is started, and during the counting period of the fourth timer (i.e., before the fourth timer expires), even if the beam meets the triggering reporting condition, the terminal device will not trigger the reporting accordingly. The beam that meets the triggering reporting condition refers to the beam whose corresponding second counter value is greater than the fifth threshold before the corresponding second timer expires. That is, if a new beam meets the triggering reporting condition and the terminal device performs the reporting of the measurement result accordingly, the new beam cannot trigger the reporting of the measurement result again in the following period (the counting period of the fourth timer corresponding to the new beam).

[0394] In the implementation manner one of the reporting of the measurement result shown in the above step 1304, after the terminal device performs the reporting of the measurement result associated with the second event, it can refer to after the terminal device completes the sending of the first uplink signaling, or after the terminal device receives the first DCI from the network device, or after the terminal device completes the sending of the second uplink signaling, or after the terminal device receives the response message of the second uplink signaling from the network device.

[0395] In the implementation manner two of the reporting of the measurement result shown in the above step 1304, after the terminal device performs the reporting of the measurement result associated with the second event, it can refer to after the terminal device completes the sending of the third uplink signaling, or after the terminal device receives the response message of the third uplink signaling from the network device, or after the terminal device completes the sending of the fourth uplink signaling, or after the terminal device receives the response message of the fourth uplink signaling from the network device.

[0396] The step 1305 is similar to the step 905 in the embodiment shown in the foregoing FIG. 9, and details can be referred to the related introduction of the step 905 in the embodiment shown in the foregoing FIG. 9, which will not be repeated here.

[0397] It should be noted that the terminal device can close the second timer corresponding to at least one new beam (i.e., all new beams) in the above step 1301, or can only close the second timer corresponding to part of the new beams in the at least one new beam in the above step 1301. The terminal device can set the second counter corresponding to at least one new beam (i.e., all new beams) in the above step 1301 to 0 (i.e., clear 0), or can set the second counter corresponding to part of the new beams in the at least one new beam in the above step 1301 to 0.

[0398] Optionally, the part of the new beams refers to the new beams corresponding to the second timer of the at least one new beam in the above step 1301 greater than or equal to the fifth threshold value. Alternatively, the part of the new beams refers to the new beams for which the terminal device reports the measurement result in the above step 1304.

[0399] Optionally, the embodiment shown in FIG. 13 further includes step 1306, which can be executed after step 1304.

[0400] 1306, for any new beam satisfying the occurrence condition of the second event, after the second timer corresponding to the new beam expires, the terminal device sets the second counter corresponding to the new beam to 0.

[0401] Thus, it is convenient to restart counting the occurrence of the second event.

[0402] Optionally, the embodiment shown in FIG. 13 further includes step 1307, which can be executed after step 1304.

[0403] 1307, when the service beam changes, the terminal device closes the second timer corresponding to all new beams corresponding to the service beam, and / or sets the second counter corresponding to all new beams corresponding to the service beam to 0.

[0404] All new beams corresponding to the service beam refer to new beams corresponding to the same measurement process or the same measurement reporting configuration of the service beam. That is, all new beams corresponding to the service beam can be understood as at least one new beam in the above step 1301.

[0405] In a possible implementation, for a cell, the service beam of the terminal device changes, which can mean that the TCI state currently in effect of the cell changes. For example, the network device indicates a new TCI state for the terminal device. Alternatively, the service beam of the terminal device changes, which can mean that the QCL resource in the TCI state currently in effect of the cell changes. Alternatively, the service beam of the terminal device changes, which can mean that the reference signal corresponding to the QCL resource associated with the QCL resource in the TCI state currently in effect of the cell changes. In this case, the terminal device closes the second timer corresponding to the new beam associated with the same reporting configuration as the service beam in the cell, and / or sets the second counter corresponding to the new beam associated with the same reporting configuration as the service beam in the cell to 0.

[0406] In another possible implementation, for a reporting configuration, when the service beam changes, the network device updates the service beam measurement resource corresponding to the reporting configuration. In this case, the terminal device closes the second timer corresponding to the new beam associated with the same reporting configuration as the service beam in the cell, and / or sets the second counter corresponding to the new beam associated with the same reporting configuration as the service beam in the cell to 0.

[0407] In the embodiments of the present application, the terminal device measures the service beam and at least one new beam to obtain a first measurement result. If the first measurement result indicates that the second event occurs, the terminal device performs an operation on the second timer corresponding to the new beam that meets the occurrence condition of the second event, and / or performs an operation on the second counter corresponding to the new beam that meets the occurrence condition of the second event. The terminal device determines whether to trigger the measurement result reporting according to the state of the second timer and / or the state of the second counter. Thus, the terminal device reasonably reports the measurement result. The terminal device avoids reporting unnecessary measurement results, and signaling overhead is saved.

[0408] In the present application, when the terminal device adopts the second mode, for the case where the second event occurs, the terminal device can also determine whether to trigger the measurement result reporting through other manners. Two possible implementation manners are introduced below in combination with the embodiments shown in FIG. 15 and FIG. 16. The present application is still applicable to other implementation manners, and the present application is not limited in this regard.

[0409] FIG. 15 is a schematic diagram of another embodiment of the beam measurement method according to an embodiment of the present application. Please refer to FIG. 15, the method comprises:

[0410] 1501. The terminal device measures the service beam and / or at least one new beam to obtain a first measurement result.

[0411] Step 1501 is similar to step 801 in the foregoing embodiment shown in FIG. 8, and details can be referred to the related description of step 801 in the foregoing embodiment shown in FIG. 8, which will not be repeated here.

[0412] 1502. If the first measurement result indicates occurrence of the second event, the terminal device triggers reporting of the measurement result.

[0413] For example, the first measurement result includes the signal quality of the serving beam and the signal quality of the at least one new beam. If the signal quality of the one or more new beams is higher than the signal quality of the serving beam by a fourth threshold value, it indicates occurrence of the second event, and then the terminal device triggers reporting of the measurement result.

[0414] Optionally, the above step 1502 can be alternatively described as: if the first measurement result indicates occurrence of the second event, the terminal device reports the measurement result corresponding to the second event; or if the first measurement result indicates occurrence of the second event, the terminal device triggers sending of the first uplink signaling or the third uplink signaling; or if the first measurement result indicates occurrence of the second event, the terminal device sends the first uplink signaling or the third uplink signaling.

[0415] Optionally, if the first condition is not met, and the first measurement result indicates occurrence of the second event, the terminal device triggers reporting of the measurement result, or the terminal device reports the measurement result corresponding to the second event, or the terminal device triggers sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling. The first condition is described above, and details will not be repeated here. In other words, if the fourth condition is met, and the first measurement result indicates occurrence of the second event, the terminal device triggers reporting of the measurement result, or the terminal device reports the measurement result corresponding to the second event, or the terminal device triggers sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling. The fourth condition is described above, and details will not be repeated here.

[0416] 1503. The terminal device sends the measurement result associated with the second event to the network device. Correspondingly, the network device receives the measurement result associated with the second event from the terminal device.

[0417] Step 1503 is similar to step 904 in the foregoing embodiment shown in FIG. 9, and details can be referred to the related description of step 904 in the foregoing embodiment shown in FIG. 9, which will not be repeated here.

[0418] In the embodiment, the terminal device measures the serving beam and the at least one new beam to obtain a first measurement result. If the first measurement result indicates that the second event occurs, the terminal device triggers the measurement result reporting. Therefore, if the second event occurs, the terminal device triggers the measurement result reporting. Thus, the measurement result associated with the second event is reported by the terminal device when the second event occurs. Therefore, unnecessary measurement results are avoided from being reported by the terminal device, and signaling overhead is saved.

[0419] FIG. 16 is a schematic diagram of another embodiment of the beam measurement method according to the present application. Referring to FIG. 16, the method comprises the following steps:

[0420] 1601. The physical layer of the terminal device measures the serving beam and the at least one new beam to obtain a first measurement result.

[0421] Step 1601 is similar to step 801 in the embodiment shown in FIG. 8, and details are referable to the related description of step 801 in the embodiment shown in FIG. 8, which will not be repeated here.

[0422] 1602. The physical layer of the terminal device sends second indication information to the MAC layer of the terminal device. Correspondingly, the MAC layer of the terminal device receives the second indication information from the physical layer of the terminal device.

[0423] The second indication information is similar to the second indication information in the embodiment shown in FIG. 14, and details are referable to the related description of the second indication information in the embodiment shown in FIG. 14, which will not be repeated here.

[0424] 1603. The MAC layer of the terminal device triggers the measurement result reporting according to the second indication information.

[0425] It should be noted that in the embodiment, the terminal device adopts a cross-layer design, that is, the physical layer and the MAC layer of the terminal device jointly determine whether to trigger the measurement result reporting.

[0426] Optionally, step 1603 can be alternatively described as: the MAC layer of the terminal device triggers the physical layer of the terminal device to report the measurement result according to the second indication information, or the MAC layer of the terminal device triggers the physical layer of the terminal device to report the measurement result corresponding to the second event according to the second indication information, or the MAC layer of the terminal device triggers the physical layer of the terminal device to send the first uplink signaling or the third uplink signaling according to the second indication information.

[0427] Optionally, if the first condition is not met, and the MAC layer of the terminal device receives the second indication information sent by the physical layer of the terminal device, the MAC layer of the terminal device triggers the measurement result reporting, or the MAC layer of the terminal device triggers the physical layer of the terminal device to report the measurement result corresponding to the second event, or the MAC layer of the terminal device triggers the physical layer of the terminal device to send the first uplink signaling or the third uplink signaling. The first condition is described above and will not be repeated here. In other words, if the fourth condition is met, and the MAC layer of the terminal device receives the second indication information sent by the physical layer of the terminal device, the MAC layer of the terminal device triggers the measurement result reporting, or the MAC layer of the terminal device triggers the physical layer of the terminal device to report the measurement result corresponding to the second event, or the MAC layer of the terminal device triggers the physical layer of the terminal device to send the first uplink signaling or the third uplink signaling. The fourth condition is described above and will not be repeated here.

[0428] 1604. The MAC layer of the terminal device sends the measurement result associated with the second event to the network device. Correspondingly, the network device receives the measurement result associated with the second event from the MAC layer of the terminal device.

[0429] Step 1604 is similar to step 904 in the embodiment shown in FIG. 9, and details are described above with reference to step 904 in the embodiment shown in FIG. 9, which will not be repeated here.

[0430] In the embodiment, the terminal device measures the serving beam and at least one new beam to obtain the first measurement result. The physical layer of the terminal device sends the second indication information to the MAC layer of the terminal device. The MAC layer of the terminal device triggers the measurement result reporting according to the second indication information. Therefore, if the second event occurs, the physical layer of the terminal device sends the second indication information to the MAC layer of the terminal device. The MAC layer of the terminal device triggers the measurement result reporting according to the second indication information. Thus, the terminal device reports the measurement result associated with the second event when the second event occurs. Therefore, unnecessary measurement results are avoided, and signaling overhead is saved.

[0431] FIG. 17 is another embodiment of the beam measurement method according to the present application. Please refer to FIG. 17, the method includes:

[0432] 1701. The terminal device measures the first activated beam and at least one new beam to obtain the first measurement result.

[0433] Step 1701 is similar to step 801 in the embodiment shown in FIG. 8, and details are described above with reference to step 801 in the embodiment shown in FIG. 8, which will not be repeated here.

[0434] The at least one new beam refers to a new beam corresponding to a same measurement procedure or a same reporting configuration as the first activated beam.

[0435] 1702. If the first measurement result represents occurrence of a third event, the terminal device performs an operation on a third timer corresponding to a new beam satisfying an occurrence condition of the third event, and / or performs an operation on a third counter corresponding to the new beam satisfying the occurrence condition of the third event.

[0436] The new beam satisfying the occurrence condition of the third event is one or more. The third event is described in the foregoing embodiment shown in FIG. 8. The new beam satisfying the occurrence condition of the third event refers to a new beam whose signal quality is higher than that of the first activated beam by a sixth threshold value. Or a new beam whose difference in signal quality from the first activated beam is greater than the sixth threshold value, or a new beam whose difference in signal quality from the first activated beam is greater than or equal to the sixth threshold value.

[0437] In a possible implementation, each new beam in the new beams satisfying the occurrence condition of the third event corresponds to a third timer and / or a third counter. Different new beams correspond to different third timers and / or different third counters. That is, the third timer and the third counter are both beam-level, and each new beam has an independent third timer and an independent third counter.

[0438] In another possible implementation, part or all of the new beams satisfying the occurrence condition of the third event correspond to a same third timer and / or a same third counter. For example, all the new beams satisfying the occurrence condition of the third event correspond to a same third timer, and each new beam in the new beams satisfying the occurrence condition of the third event corresponds to a third counter, and different new beams correspond to different third counters. That is, all the new beams satisfying the occurrence condition of the third event share a same third timer, that is, the third timers corresponding to the new beams are the same. For another example, all the new beams satisfying the occurrence condition of the third event correspond to a same third counter, and each new beam in the new beams satisfying the occurrence condition of the third event corresponds to a third timer, and different new beams correspond to different third timers. That is, all the new beams satisfying the occurrence condition of the third event share a same third counter, that is, the third counters corresponding to the new beams are the same.

[0439] Hereinafter, the technical solution of the present application is mainly described by taking each new beam corresponding to a third timer and a third counter as an example.

[0440] Optionally, the terminal device performs an operation on a third timer corresponding to a new beam satisfying the occurrence condition of the third event, including: for any new beam satisfying the occurrence condition of the third event, the terminal device starts or restarts the third timer corresponding to the new beam. Alternatively, for a first new beam in the new beams satisfying the occurrence condition of the third event, the terminal device starts or restarts the third timer corresponding to the first new beam. Optionally, the terminal device performs an operation on a third counter corresponding to a new beam satisfying the occurrence condition of the third event, including: for any new beam satisfying the occurrence condition of the third event, the terminal device adds one to the value of the third counter corresponding to the new beam. Alternatively, for a first new beam in the new beams satisfying the occurrence condition of the third event, the terminal device adds one to the value of the third counter corresponding to the first new beam.

[0441] Specifically, for any new beam satisfying the occurrence condition of the third event, if the third timer corresponding to the new beam is not started, the terminal device starts the third timer corresponding to the new beam and adds one to the value of the third counter corresponding to the new beam. If the third timer corresponding to the new beam has been started, the terminal device restarts the third timer corresponding to the new beam (i.e., restarts timing from the initial value) and adds one to the value of the third counter corresponding to the new beam. That is, the terminal device starts or restarts the third timer corresponding to the new beam and adds one to the value of the third counter corresponding to the new beam. Optionally, if the third timer corresponding to the new beam has been started, the terminal device can only add one to the value of the third counter corresponding to the new beam, and the terminal device does not restart the third timer corresponding to the new beam.

[0442] In an example, when the third event occurs, for a certain new beam satisfying the occurrence condition of the third event, if the value of the third counter corresponding to the new beam is 0 and the third timer corresponding to the new beam is not timing, the terminal device starts the third timer and adds one to the value of the third counter. For example, the value of the third counter corresponding to the new beam is 0 and the third timer corresponding to the new beam is not timing. In the case that the new beam satisfies the occurrence condition of the third event, the terminal device starts the third timer corresponding to the new beam (i.e., the third timer starts timing), and the terminal device adds one to the value of the third counter corresponding to the new beam (i.e., the value recorded by the third counter is updated to 1).

[0443] In another example, when the third event occurs, for a new beam that satisfies the occurrence condition of the third event, if the value of the third counter corresponding to the new beam is greater than 0 and the third timer corresponding to the new beam is not timing, the terminal device starts the third timer corresponding to the new beam, and adds 1 to the value of the third counter corresponding to the new beam. For example, the value of the third counter corresponding to the new beam is 1, and the third timer corresponding to the new beam is not timing. In the case where the new beam satisfies the occurrence condition of the third event, the terminal device starts the third timer corresponding to the new beam (i.e., the third timer starts timing), and the terminal device adds 1 to the value of the third counter corresponding to the new beam (i.e., the value recorded by the third counter is updated to 2).

[0444] In another example, when the third event occurs, for a new beam that satisfies the occurrence condition of the third event, if the value of the third counter corresponding to the new beam is greater than 0 and the third timer corresponding to the new beam is timing, the terminal device restarts the third timer corresponding to the new beam, and adds 1 to the value of the third counter corresponding to the new beam. For example, the value of the third counter corresponding to the new beam is 1, and the third timer corresponding to the new beam is timing. In the case where the new beam satisfies the occurrence condition of the third event, the terminal device restarts the third timer corresponding to the new beam (i.e., the third timer starts timing), and the terminal device adds 1 to the value of the third counter corresponding to the new beam (i.e., the value recorded by the third counter is updated to 2).

[0445] In another example, when the third event occurs, for a new beam that satisfies the occurrence condition of the third event, if the value of the third counter corresponding to the new beam is greater than 0 and the third timer corresponding to the new beam is timing, the terminal device adds 1 to the value of the third counter corresponding to the new beam. For example, the value of the third counter corresponding to the new beam is 1, and the third timer corresponding to the new beam is timing. In the case where the new beam satisfies the occurrence condition of the third event, the third timer corresponding to the new beam continues to time, and the terminal device adds 1 to the value of the third counter corresponding to the new beam (i.e., the value recorded by the third counter is updated to 2).

[0446] Optionally, after step 1701 and before step 1702, the method further includes step 1801 in the embodiment shown in FIG. 18.

[0447] 1801. The physical layer of the terminal device sends the third indication information to the MAC layer of the terminal device. Correspondingly, the MAC layer of the terminal device receives the third indication information from the physical layer of the terminal device.

[0448] The third indication information is used to indicate occurrence of a third event. Optionally, the third indication information is also used to indicate at least one of the following: an event index corresponding to the third event, an event type corresponding to the third event, information of the first active beam, or information of a new beam satisfying an occurrence condition of the third event. The information of the serving beam includes at least one of the following: an index of the serving beam, or a signal quality of the serving beam. The information of the new beam satisfying the occurrence condition of the third event includes at least one of the following: an index of the new beam satisfying the occurrence condition of the third event, a signal quality of the new beam satisfying the occurrence condition of the third event, or a signal quality difference between the new beam satisfying the occurrence condition of the third event and the first active beam.

[0449] In this implementation, the step 1702 specifically includes: if the first measurement result represents occurrence of the third event, the MAC layer of the terminal device performs the above-mentioned operation on a third counter corresponding to the new beam satisfying the occurrence condition of the third event, and / or the MAC layer of the terminal device performs the above-mentioned operation on the third counter corresponding to the new beam satisfying the occurrence condition of the third event. In this implementation, the terminal device adopts a cross-layer design, i.e., the physical layer and the MAC layer of the terminal device jointly determine whether to trigger reporting of the measurement result.

[0450] In another possible implementation, the terminal device adopts a non-cross-layer design, i.e., the physical layer of the terminal device determines whether to trigger reporting of the measurement result, or the physical layer of the terminal device determines whether to report the measurement result corresponding to the third event, or the physical layer of the terminal device determines whether to trigger sending of the first uplink signaling or the third uplink signaling, or the physical layer of the terminal device determines whether to send the first uplink signaling or the third uplink signaling. For the first uplink signaling and the third uplink signaling, refer to the foregoing relevant description. That is, the step 1702 is an operation performed by the physical layer of the terminal device. That is, the physical layer of the terminal device performs the above-mentioned operation on a third timer corresponding to the new beam satisfying the occurrence condition of the third event, and / or the physical layer of the terminal device performs the above-mentioned operation on a third counter corresponding to the new beam satisfying the occurrence condition of the third event.

[0451] Optionally, if the first condition is satisfied and the first measurement result represents occurrence of the third event, the terminal device performs an operation on a third timer corresponding to the new beam satisfying the occurrence condition of the third event, and / or the terminal device performs an operation on a third counter corresponding to the new beam satisfying the occurrence condition of the third event. The first condition is described in the foregoing step 902 of the embodiment shown in FIG. 9, and thus is not described here again.

[0452] In this implementation, the terminal device reports the measurement result in the first mode, or in other words, the terminal device supports reporting the measurement result in the first mode.

[0453] 1703、The terminal device determines whether to trigger reporting of the measurement result according to a state of the third timer and / or a state of the third counter.

[0454] Specifically, if there is at least one new beam satisfying the fifth condition among the new beams satisfying the occurrence condition of the third event, the terminal device triggers reporting of the measurement result. The fifth condition includes that the value of the third counter corresponding to the at least one new beam is greater than or equal to a fifth threshold value before the third timer corresponding to the at least one new beam expires. Alternatively, the fifth condition includes that the value of the third counter corresponding to the at least one new beam is greater than the fifth threshold value before the third timer corresponding to the at least one new beam expires. For example, if the new beams satisfying the occurrence condition of the third event include a first new beam, and the value of the third counter corresponding to the first new beam is greater than or equal to the fifth threshold value before the third timer corresponding to the first new beam expires, the terminal device triggers reporting of the measurement result.

[0455] Alternatively, the terminal device determines whether to trigger reporting of the measurement result according to a state of the third timer and / or a state of the third counter can be replaced by: the terminal device determines whether to report the measurement result according to a state of the third timer and / or a state of the third counter, or the terminal device determines whether to trigger sending of the first uplink signaling or determines whether to send the first uplink signaling according to a state of the third timer and / or a state of the third counter, or the terminal device determines whether to trigger sending of the third uplink signaling or determines whether to send the third uplink signaling according to a state of the third timer and / or a state of the third counter, or the terminal device determines whether to trigger reporting of the measurement result corresponding to the third event according to a state of the third timer and / or a state of the third counter, or the terminal device determines whether to report the measurement result corresponding to the third event according to a state of the third timer and / or a state of the third counter.

[0456] Alternatively, in the case where the first condition is satisfied, if there is at least one new beam satisfying the fifth condition among the new beams satisfying the occurrence condition of the third event, the terminal device triggers reporting of the measurement result, or the terminal device reports the measurement result corresponding to the third event, or the terminal device triggers sending of the first uplink signaling or the third uplink signaling, or the terminal device sends the first uplink signaling or the third uplink signaling.

[0457] If the first condition is not satisfied, when the first measurement result indicates occurrence of the third event, the physical layer of the terminal device or the MAC layer of the terminal device directly triggers reporting of the measurement result, without the need to determine whether to trigger reporting of the measurement result according to a state of the third timer and / or a state of the third counter. Alternatively, if the first condition is not satisfied, when the first measurement result indicates occurrence of the third event, the physical layer of the terminal device or the MAC layer of the terminal device directly triggers reporting of the measurement result, without the need to determine whether to trigger reporting of the measurement result according to the fifth condition.

[0458] In a possible implementation, the terminal device determines whether to trigger the measurement result reporting according to the state of the third timer and / or the state of the third timer regardless of whether the first condition is met. The difference lies in that, if the first condition is met, the fifth threshold value can be an integer greater than or equal to 1. Optionally, the fifth threshold value is a positive integer configured by the network device for the terminal device. If the first condition is not met, the fifth threshold value is 1 by default. Of course, the fifth threshold value can also be configured by the network device, but can only be configured as 1. For the first condition, refer to the foregoing relevant introduction. In other words, if the fourth condition is met, the fifth threshold value is 1. For the fourth condition, refer to the foregoing relevant introduction. In this implementation, the terminal device reports the measurement result in the second mode, or the terminal device supports reporting the measurement result in the second mode.

[0459] If the terminal device reports the measurement result in the second mode, the value of the fifth threshold value is 1. As long as the third event occurs once, the terminal device can trigger the measurement result reporting. Or, according to the communication protocol, when the terminal device adopts the second mode, the value of the fifth threshold value is 1; or, according to the communication protocol, when the terminal device adopts the second mode, the network device can only configure the value of the fifth threshold value as 1.

[0460] For example, the terminal device determines whether to trigger the measurement result reporting by using a cross-layer design. In the step 1703, the MAC layer of the terminal device determines whether to trigger the measurement result reporting according to the state of the third timer and / or the state of the third counter. Or, the MAC layer of the terminal device determines whether to report the measurement result corresponding to the third event according to the state of the third timer and / or the state of the third counter. Or, the MAC layer of the terminal device determines whether to trigger the sending of the first uplink signaling or the third uplink signaling according to the state of the third timer and / or the state of the third counter. Or, the MAC layer of the terminal device determines whether to send the first uplink signaling or the third uplink signaling according to the state of the third timer and / or the state of the third counter.

[0461] For another example, the terminal device determines whether to trigger the measurement result reporting by using a non-cross-layer design. In the step 1703, the physical layer of the terminal device determines whether to trigger the measurement result reporting according to the state of the third timer and / or the state of the third counter. Or, the physical layer of the terminal device determines whether to report the measurement result corresponding to the third event according to the state of the third timer and / or the state of the third counter. Or, the physical layer of the terminal device determines whether to trigger the sending of the first uplink signaling or the third uplink signaling according to the state of the third timer and / or the state of the third counter. Or, the physical layer of the terminal device determines whether to send the first uplink signaling or the third uplink signaling according to the state of the third timer and / or the state of the third counter.

[0462] Optionally, when the terminal device triggers the measurement result reporting, the embodiment shown in FIG. 17 further includes step 1704. Step 1704 can be performed after step 1703.

[0463] 1704. The terminal device sends the measurement result associated with the third event to the network device. Correspondingly, the network device receives the measurement result associated with the third event from the terminal device.

[0464] The measurement result associated with the third event includes the information of the serving beam and / or the information of the new beam satisfying the occurrence condition of the third event. The information of the serving beam and the information of the new beam satisfying the occurrence condition of the third event are described above, and will not be repeated here. The measurement result associated with the third event can include part or all of the measurement result in the first measurement result. For example, the first measurement result includes the signal quality of the first active beam, the signal quality of the first new beam, and the signal quality of the second new beam. The first new beam satisfies the occurrence condition of the third event, and the second new beam does not satisfy the occurrence condition of the third event. The measurement result associated with the third event can include the signal quality of the first active beam and the signal quality of the first new beam.

[0465] The following describes two possible implementation manners of the terminal device reporting the measurement result associated with the third event.

[0466] Implementation manner one: the terminal device sends first uplink signaling to the network device, and the first uplink signaling is used to request the network device to schedule uplink resources. Then, the network device sends first DCI to the terminal device, and the first DCI is used to schedule first uplink resources. The terminal device sends second uplink signaling to the network device through the first uplink resources. The second uplink signaling includes the measurement result associated with the third event. Optionally, the first uplink signaling is a PUCCH signal or an SR signal.

[0467] Implementation manner two: the terminal device sends third uplink signaling to the network device. The third uplink signaling is used to inform the network device that the terminal device reports the measurement result through fourth uplink signaling associated with the third uplink signaling. Optionally, the third uplink signaling is a PUCCH signal or an SR signal. Then, the terminal device sends the fourth uplink signaling to the network device, and the fourth uplink signaling includes the measurement result associated with the third event.

[0468] Optionally, the embodiment shown in FIG. 17 further includes step 1705, which can be performed after step 1704.

[0469] 1705、For any new beam satisfying the occurrence condition of the third event, the terminal device closes the third timer corresponding to part or all of the new beams in the new beams satisfying the occurrence condition of the third event, and / or sets the third counter corresponding to part or all of the new beams in the new beams satisfying the occurrence condition of the third event to 0.

[0470] Specifically, after the terminal device performs the measurement result reporting associated with the third event, the terminal device closes or stops the third timer corresponding to part or all of the new beams in the new beams satisfying the occurrence condition of the third event, and / or sets the third counter corresponding to part or all of the new beams in the new beams satisfying the occurrence condition of the third event to 0.

[0471] In combination with the implementation manner one of the measurement result reporting shown in the above step 1704, after the terminal device performs the measurement result reporting associated with the third event, it can mean that after the terminal device completes the sending of the first uplink signaling, or after the terminal device receives the first DCI from the network device, or after the terminal device completes the sending of the second uplink signaling, or after the terminal device receives the response message of the second uplink signaling from the network device.

[0472] In combination with the implementation manner two of the measurement result reporting shown in the above step 1704, after the terminal device performs the measurement result reporting associated with the third event, it can mean that after the terminal device completes the sending of the third uplink signaling, or after the terminal device receives the response message of the third uplink signaling from the network device, or after the terminal device completes the sending of the fourth uplink signaling, or after the terminal device receives the response message of the fourth uplink signaling from the network device.

[0473] The step 1705 is similar to the step 905 in the embodiment shown in the foregoing FIG. 9, and specific reference can be made to the related introduction of the step 905 in the embodiment shown in the foregoing FIG. 9, which will not be repeated here.

[0474] It should be noted that the terminal device can close the third timer corresponding to at least one new beam (i.e. all new beams) in the above step 1701, or can only close the third timer corresponding to part of the new beams in the at least one new beam in the above step 1701. The terminal device can set the third counter corresponding to at least one new beam (i.e. all new beams) in the above step 1701 to 0 (i.e. clear 0), or can set the third counter corresponding to part of the new beams in the at least one new beam in the above step 1701 to 0.

[0475] Optionally, the part of new beams refers to new beams corresponding to at least one new beam in step 1701 and having a third timer greater than or equal to a fifth threshold. Alternatively, the part of new beams refers to new beams for which the terminal device reports measurement results in step 1704.

[0476] Optionally, the embodiment shown in FIG. 17 further includes step 1706, which can be performed after step 1703.

[0477] 1706、For any new beam satisfying the occurrence condition of the third event, the terminal device sets the third counter corresponding to the new beam to 0 after the third timer corresponding to the new beam expires.

[0478] Thus, it is convenient to restart counting the occurrence of the third event.

[0479] Optionally, the embodiment shown in FIG. 17 further includes step 1707, which can be performed after step 1703.

[0480] 1707、When the first active beam changes, the terminal device closes the third timer corresponding to all new beams corresponding to the service beam, and / or sets the third counter corresponding to all new beams corresponding to the service beam to 0. Wherein, all new beams corresponding to the service beam can be understood as at least one new beam in the foregoing step 1701.

[0481] In one possible implementation, for a cell, the current active beam changes can mean that the current active set of beams changes. For example, the network device reactivates a set of TCI states for the terminal device. Alternatively, the current active beam changes can mean that the first active beam changes. Alternatively, the service beam of the terminal device changes can mean that the QCL resource in the TCI state corresponding to the first active beam or the SSB resource associated with the QCL resource changes. In this case, the terminal device closes the third timer corresponding to at least one new beam, and / or sets the third counter corresponding to at least one new beam to 0.

[0482] In the embodiments of the present application, the terminal device measures the first active beam and at least one new beam to obtain a first measurement result. If the first measurement result indicates that the third event occurs, the terminal device performs operations on the third timer corresponding to the new beam satisfying the occurrence condition of the third event, and / or performs operations on the third counter corresponding to the new beam satisfying the occurrence condition of the third event. The terminal device determines whether to trigger measurement result reporting according to the state of the third timer and / or the state of the third counter. Thus, the terminal device reasonably reports measurement results. Avoids the terminal device from reporting unnecessary measurement results, and saves signaling overhead.

[0483] In the present application, when the terminal device adopts the second mode, the terminal device can also determine whether to trigger the measurement result reporting through other manners in the case of the occurrence of the third event. The following...
