TECHNICAL FIELD

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

[0003] The fifth generation (5G) mobile communication system 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 signal 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 need to use beams for transmission. When performing 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, and then the network device and the terminal device communicate through the selected beam. Specifically, the terminal device can measure the reference signal from the network device to obtain a measurement result. The terminal device can report the measurement result to the network device. In release 19 (R19), a user equipment (UE) or event triggered reporting mode is introduced. The terminal device can report a measurement report related to the event. Therefore, how to trigger the reporting of the measurement report is a problem worth considering. SUMMARY

[0005] The present application provides a method for sending measurement report, a method for receiving measurement report and related apparatus, which are used for a terminal device to send a first measurement report triggered by an event to a network device through a first uplink resource scheduled by the network device. The present application avoids unnecessary reporting of measurement report and reduces the reporting overhead.

[0006] The first aspect of the present application provides a measurement report sending method, which can be used in a terminal side communication device, for example, executed by a terminal device. The terminal 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 foregoing devices or apparatus, and the present application does not make any limitation. 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, functional module, or integrated circuit in the terminal device that completes the method provided by the present application, and the present application does not make any limitation. In the first aspect and its possible implementation manners, the method is described by taking the example that the method is executed by a terminal device. The method comprises: receiving, by a terminal device, scheduling signaling from a network device, the scheduling signaling being used for scheduling a first uplink resource, the scheduling signaling comprising first indication information, the first indication information being used for determining that the first uplink resource is used for carrying an event-triggered measurement report; and sending, by the terminal device, the event-triggered first measurement report to the network device through the first uplink resource.

[0007] In the above technical solution, the terminal device receives the scheduling signaling from the network device, the scheduling signaling comprises the first indication information, and the first indication information is used for determining that the first uplink resource is used for carrying the event-triggered measurement report. Then the terminal device sends the event-triggered first measurement report to the network device through the first uplink resource. The terminal device reports the event-triggered first measurement report to the network device. The event-triggered reporting is beneficial to avoiding unnecessary measurement report reporting and reducing reporting overhead. It should be noted that in the above first aspect, the network device can also send the first indication information to the terminal device through independent signaling, and the present application does not make any limitation. The above scheduling signaling can also be described as: the scheduling signaling is used for scheduling the reporting of the event-triggered measurement report, and the scheduling signaling is used for scheduling the first uplink resource.

[0008] The second aspect of the present application provides a measurement report receiving method, which can be used in a network side communication device, for example, executed by a network equipment, which 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 foregoing devices or apparatus, and the specific embodiments of the present application are not limited. It should be noted that in the present application, when referring to the network equipment, it can refer to the network equipment itself, or the chip, functional module or integrated circuit in the network equipment that completes the method provided by the present application, and the specific embodiments of the present application are not limited. In the second aspect and its possible implementation manners, the method is taken as an example executed by the network equipment. The method comprises: the network equipment sends scheduling signaling to a terminal equipment, the scheduling signaling is used for scheduling a first uplink resource, the scheduling signaling comprises first indication information, the first indication information is used for determining that the first uplink resource is used for carrying an event triggered measurement report; and the network equipment receives the event triggered first measurement report from the terminal equipment through the first uplink resource.

[0009] In the above technical solution, the network equipment sends scheduling signaling to the terminal equipment, the scheduling signaling is used for scheduling a first uplink resource, the scheduling signaling comprises first indication information, the first indication information is used for determining that the first uplink resource is used for carrying an event triggered measurement report. The network equipment receives the event triggered first measurement report from the terminal equipment through the first uplink resource. The implementation of the event triggered reporting is beneficial to avoid the terminal equipment reporting unnecessary measurement results and saving signaling overhead. It should be noted that in the above second aspect, the network equipment can also send the first indication information to the terminal equipment through independent signaling, and the specific embodiments of the present application are not limited. The above scheduling signaling can also be described as: the scheduling signaling is used for scheduling the reporting of the event triggered measurement report, and the scheduling signaling is used for scheduling the first uplink resource.

[0010] Based on the first aspect or the second aspect, in a possible implementation manner, the scheduling signaling comprises a first field, and the first indication information is carried in the first field.

[0011] Based on the first aspect or the second aspect, in a possible implementation manner, the first field indicates a first type of trigger state, and the first type of trigger state is associated with one or more event triggered reporting configurations. In this implementation manner, the first field indicates the first type of trigger state. Thus, the terminal equipment is instructed to report the event triggered measurement report. Further, the first type of trigger state is associated with one or more event triggered reporting configurations, so that the terminal equipment can report the measurement report of the event associated with the one or more event triggered reporting configurations. The direct indication of the channel state information report (CSI report) is avoided, and the indication overhead is reduced.

[0012] In a possible implementation of the first aspect, before the method, the method further includes: receiving, by the terminal device, first activation signaling from the network device, the first activation signaling being used to activate one or more trigger states in a trigger state list configured by the network device for the terminal device, the one or more trigger states including a first type of trigger state indicated by a first field. In this implementation, the network device can activate part of the trigger states in the trigger state list through the first activation signaling. The part of the trigger states includes at least one first type of trigger state. Thus, the corresponding first type of trigger state is indicated by the value of the first field, so as to instruct the terminal device to report the measurement report based on the event trigger.

[0013] In a possible implementation of the first aspect, before or after the terminal device receives the first activation signaling from the network device, the method further includes: sending, by the terminal device, second indication information, the second indication information being carried in one or more second uplink resources, the second indication information being used to request the network device to schedule one or more first uplink resources for the terminal device, or the second indication information being used to indicate occurrence of an event associated with one or more event trigger reporting configurations, the one or more second uplink resources being second uplink resources associated with at least one first type of trigger state activated by the first activation signaling, the second uplink resources associated with the at least one first type of trigger state being the second uplink resources associated with the one or more event trigger reporting configurations, the one or more event trigger reporting configurations being event trigger reporting configurations associated with the at least one first type of trigger state. In this implementation, for the first type of trigger state that has been activated, when the event associated with the event trigger reporting configuration associated with the first type of trigger state occurs or meets a condition for occurrence, the terminal device can send the second indication information. Thus, the network device can schedule the first uplink resource for the terminal device. Further, the second indication information is carried in the one or more second uplink resources, and the one or more second uplink resources are the second uplink resources associated with the at least one first type of trigger state activated by the first activation signaling. The network device can indicate one of the at least one first type of trigger state. Thus, the network device can report the measurement result corresponding to the event trigger reporting configuration associated with the trigger state.

[0014] In a possible implementation of the first aspect, the terminal device sends second indication information, the second indication information is carried in a second uplink resource, the second indication information is used to request the network device to schedule a first uplink resource for the terminal device, or the second indication information is used to indicate occurrence of an event associated with one or more event-triggered report configurations, the second uplink resource is a second uplink resource associated with at least one first-type trigger state in the first activated signaling activated first-type trigger state, the second uplink resource associated with the at least one first-type trigger state is a second uplink resource associated with the one or more event-triggered report configurations, and the one or more event-triggered report configurations are event-triggered report configurations associated with the at least one first-type trigger state. In this implementation, for the first-type trigger state that has been activated, when an event associated with the event-triggered report configuration of the first-type trigger state occurs or meets a condition for occurrence, the terminal device can send the second indication information through the second uplink resource associated with the first-type trigger state.

[0015] The above implementation can also be an independent aspect. In the case of an independent aspect, a possible alternative of the above implementation is described as follows: The present application provides a communication method, including: if a first-type trigger state is not activated, a terminal device does not send one or more second uplink resources, or does not send first indication information through the one or more second uplink resources, or does not monitor one or more events, or does not measure one or more reference signal resources; wherein the first indication information is used to request a network device to schedule a first uplink resource for the terminal device, the first uplink resource is used to carry an event-triggered measurement report, the one or more second uplink resources are second uplink resources associated with the first-type trigger state, the second uplink resources associated with the first-type trigger state are second report resources associated with one or more event-triggered report configurations, the one or more event-triggered report configurations are event-triggered report configurations associated with the first-type trigger state, the one or more events are events associated with the one or more event-triggered report configurations, and the one or more reference signal resources are reference signal resources associated with the one or more event-triggered report configurations. That is, if a first-type trigger state is not activated, the terminal device does not send first indication information through one or more second uplink resources, or does not monitor one or more events, or does not measure one or more reference signal resources. Thus, unnecessary resource waste is avoided. For example, measurement resource waste and report resource waste.

[0016] In the alternative described scheme, the first-type trigger state is associated with one or more event-triggered report configurations, the one or more event-triggered report configurations are associated with a same second uplink resource. When the first-type trigger state is not activated, the terminal device does not send the second uplink resource.

[0017] In the alternative described scheme, optionally, the first type of trigger state is associated with a plurality of event triggered reporting configurations, and different event triggered reporting configurations in the plurality of event triggered reporting configurations are associated with different second uplink resources. When the first type of trigger state is not activated, the terminal device does not send the second uplink resources associated with the plurality of event triggered reporting configurations.

[0018] In the alternative described scheme, optionally, the method further includes: the terminal device receiving, from the network device, one or more trigger states, the one or more trigger states being the first type of trigger state, and each trigger state in the one or more trigger states being associated with one or more event triggered reporting configurations.

[0019] In the alternative described scheme, optionally, different trigger states in the one or more trigger states are associated with different second uplink resources.

[0020] In the alternative described scheme, optionally, one trigger state in the one or more trigger states is associated with one or more event triggered reporting configurations, and the one or more event triggered reporting configurations are associated with the same second uplink resource.

[0021] In the alternative described scheme, optionally, different trigger states in the one or more trigger states are associated with the same second uplink resource.

[0022] Based on the second aspect, in a possible implementation, the method further includes: the network device sending, to the terminal device, first activation signaling, the first activation signaling being used to activate one or more trigger states in a trigger state list configured by the network device for the terminal device, and the one or more trigger states including the first type of trigger state indicated by the first field. Thus, it is implemented to activate part of the trigger states in the trigger state list. The part of the trigger states includes at least one first type of trigger state. Thus, it is implemented to indicate the terminal device to report the measurement report based on the event trigger by indicating the corresponding first type of trigger state through the value of the first field.

[0023] Based on the first aspect or the second aspect, in a possible implementation, one first type of trigger state in the first type of trigger states activated by the first activation signaling is associated with one or more event triggered reporting configurations, and the one or more event triggered reporting configurations are associated with the same second uplink resource.

[0024] Based on the first aspect or the second aspect, in a possible implementation, one first type of trigger state in the first type of trigger states activated by the first activation signaling is associated with a plurality of event triggered reporting configurations, and different event triggered reporting configurations in the plurality of event triggered reporting configurations are associated with different second uplink resources.

[0025] In a possible implementation of the first aspect or the second aspect, in the first type of trigger states activated by the first activation signaling, different first type of trigger states are associated with different second uplink resources. Thus, the network device can learn which trigger state is associated with the event through the second uplink resource. No additional indication is needed, and the indication overhead is reduced.

[0026] In a possible implementation of the first aspect or the second aspect, the one or more trigger states include an (i+1)th trigger state in the list of trigger states, the (i+1)th trigger state corresponds to a Ti field in the first activation signaling, a value of the Ti field is 1, i is an integer greater than or equal to 0. In other words, each trigger state in the one or more trigger states corresponds to a T field in the first activation signaling, and a value of the T field is 1. The T field in the first activation signaling is used to determine whether each trigger state is activated. For example, the value of i can be one or more integer values in the interval [0, F-1], and F is the number of trigger states in the list of trigger states. The maximum value of i can be F-1.

[0027] In a possible implementation of the first aspect or the second aspect, the one or more trigger states include M trigger states, and M values of the first field correspond to the M trigger states, M is an integer greater than or equal to 1. For example, the M values include a jth value, and the jth value is used for a jth trigger state in the M trigger states, j is an integer greater than or equal to 1 and less than or equal to M. For example, the M values include a value j1, and the value j1 is used to indicate a jth trigger state in the M trigger states, j1 is an integer greater than or equal to 1 and less than or equal to 2 N -1, and N is the length of the first field. The value of the first field is used to indicate the corresponding first type of trigger state. The network device is instructed to report the measurement report triggered by the event.

[0028] In a possible implementation of the first aspect or the second aspect, the one or more trigger states include K first type of trigger states, each first type of trigger state in the K first type of trigger states corresponds to a Ti field in the first activation signaling, and a value of the Ti field is 1, K is an integer greater than or equal to 1. The Ti field in the first activation signaling is used to activate the first type of trigger state. Each first type of trigger state in the K first type of trigger states corresponds to a Ti field, and when the value of the Ti field is 1, the first type of trigger state is activated.

[0029] In a possible implementation of the first aspect or the second aspect, the network device configures K first-type trigger states in the trigger state list for the terminal device, K is an integer greater than or equal to 1, and the K values of the first field correspond to the K first-type trigger states. For example, the K values of the first field include an a-th value, the a-th value is used to indicate an a-th first-type trigger state, the a-th first-type trigger state includes the first-type trigger state indicated by the first field, K is an integer greater than or equal to 1, and a is an integer greater than or equal to 1 and less than or equal to K. In this implementation, the K values of the first field can be mapped to the K first-type trigger states in the trigger state list by default. The a-th value of the first field is used to indicate the a-th first-type trigger state. The implementation indicates the network device to report the measurement report triggered by the event by indicating the corresponding first-type trigger state through the value of the first field. In other words, the K values of the first field include a value a1, the value a1 is used to indicate the a-th first-type trigger state in the K first-type trigger states, a1 is an integer greater than or equal to 1 and less than or equal to 2 N -1, and N is the length of the first field.

[0030] In a possible implementation of the first aspect or the second aspect, the K values of the first field are 1 to K, or 2 N -K to 2 N -1, and N is the length of the first field. In this implementation, the above K first-type trigger states can be mapped to the above K values shown in the table, so as to facilitate the network device to indicate the first-type trigger state by using one of the K values of the first field.

[0031] In a possible implementation of the first aspect, the method further includes: receiving, by the terminal device, second activation signaling from the network device, wherein the second activation signaling is used to activate Q second-type trigger states in the trigger state list, the second-type trigger state is associated with one or more non-event-triggered reporting configurations, Q is an integer greater than or equal to 1 and less than or equal to 2 L -1-K, L is the length of the first field, or L is a configurable maximum value of the length of the first field specified in the communication protocol. In this implementation, the K first-type trigger states in the trigger state list are activated after being configured. Optionally, the network device can also activate the Q second-type trigger states in the trigger state list. The network device can map the other values of the first field to the second-type trigger states. The implementation indicates the terminal device to report the measurement report triggered by the non-event. Optionally, L can be replaced by N, and N is the length of the first field.

[0032] In a possible implementation of the second aspect, the method further includes: sending, by the network device, second activation signaling to the terminal device, where the second activation signaling is used to activate Q second-type trigger states in the trigger state list, the second-type trigger state is associated with one or more non-event-triggered reporting configurations, Q is greater than or equal to 1 and less than or equal to 2 L -1, where K is an integer, and L is the length of the first field, or L is a configurable maximum value of the length of the first field specified by a communication protocol. In this implementation, the default K first-type trigger states in the trigger state list are activated after being configured. Optionally, the network device can also activate Q second-type trigger states in the trigger state list. The network device can map other values of the first field to the second-type trigger states. This implementation indicates the terminal device to report a measurement report based on non-event triggering. Optionally, L can be replaced by N, where N is the length of the first field.

[0033] In a possible implementation of the first aspect or the second aspect, the number of second-type trigger states in the trigger state list is greater than 2 N -1, where K is an integer, and N is the length of the first field, and N=L.

[0034] In a possible implementation of the first aspect or the second aspect, the number of trigger states in the trigger state list is greater than 2 N -1, where N is the length of the first field, and N=L.

[0035] In a possible implementation of the first aspect or the second aspect, P values of the first field correspond to trigger states in the trigger state list configured by the network device for the terminal device, the trigger state list includes at least one first-type trigger state, and P is an integer greater than or equal to 1. For example, the P values of the first field include the bth value, the bth value is used to indicate the bth trigger state in the trigger state list, the P values of the first field are P values other than 0, P is the number of trigger states in the trigger state list, and b is an integer greater than or equal to 1 and less than or equal to P. In this implementation, each trigger state in the trigger state list corresponds to a value of the first field. This implementation indicates the first-type trigger state, to indicate the network device to report a measurement report based on event triggering to the terminal device. For example, the P values of the first field include the value b1, the value b1 is used to indicate the bth trigger state in the trigger state list, and b1 is an integer greater than or equal to 1 and less than or equal to 2 N -1, where K is an integer, and N is the length of the first field.

[0036] In a possible implementation of the first aspect or the second aspect, the P values of the first field correspond to the trigger states in the trigger state list in ascending order.

[0037] In a possible implementation of the first aspect or the second aspect, the number of trigger states in the trigger state list is less than or equal to 2 N -1, and N is the length of the first field.

[0038] In a possible implementation of the first aspect or the second aspect, the first field indicates all first-type trigger states configured by the network device for the terminal device, or indicates all first-type trigger states activated by the network device for the terminal device; the value of the first field is a first value, and the first value is configured by the network device, or is specified by a communication protocol, or is predefined, or is reported by the terminal device, and the first value is 1 to 2 N -1, and N is the length of the first field. In this implementation, when the value of the first field is the first value, the terminal device is instructed to report the measurement report triggered by the event. The special value of the first field is used to instruct the terminal device to report the measurement report triggered by the event. The indication overhead is reduced.

[0039] In a possible implementation of the first aspect or the second aspect, if the first condition is met and the value of the first field is the first value, the first uplink resource scheduled by the scheduling signaling is used to carry the measurement report triggered by the event, and the first condition includes at least one of the following: the terminal device is configured with the event-triggered reporting configuration; the terminal device is configured with the event-triggered reporting configuration in mode A; or the terminal device sends second indication information to the network device before the scheduling signaling, and the second indication information is used to indicate that there is an event occurrence or a need to report the measurement report triggered by the event. The terminal device reports the measurement report triggered by the event when the corresponding condition is met.

[0040] In a possible implementation of the first aspect, the method further includes: receiving, by the terminal device, third activation signaling from the network device, the third activation signaling is used to activate Y second-type trigger states in the trigger state list configured by the network device for the terminal device, the second-type trigger state is associated with one or more non-event-triggered reporting configurations, and Y is greater than or equal to 1 and less than or equal to 2 Lan integer of 0 to 2, L is a length of the first field, or L is a configurable maximum value of the length of the first field specified by a communication protocol; Y values of the first field correspond to Y second-type trigger states. For example, the Y values include a c th value, the c th value is used to indicate a c th second-type trigger state of the Y second-type trigger states, the Y values of the first field are Y values of the first field except 0 and the first value, and c is an integer greater than or equal to 1 and less than or equal to Y. Optionally, the Y values of the first field include a value c 1, the value c 1 is used to indicate a c th second-type trigger state of the Y second-type trigger states. c 1 is 1 to 2 N one of the values except 0 and the first value in the integer of 0 to 1, and N is a length of the first field.

[0041] In this implementation, for the scheme that the special value of the first field is used to indicate that the terminal device reports the measurement report based on the event trigger, the network device can further activate Y second-type trigger states in the trigger state list. The Y values of the first field correspond to the Y second-type trigger states, thereby facilitating the network device to indicate the second-type trigger state through the value of the first field.

[0042] Based on the second aspect, in a possible implementation, the method further includes: the network device sends third activation signaling to the terminal device, the third activation signaling is used to activate Y second-type trigger states in the trigger state list configured by the network device for the terminal device, the second-type trigger state is associated with one or more non-event trigger reporting configurations, and Y is an integer greater than or equal to 1 and less than or equal to 2 L an integer of 0 to 2, L is a length of the first field, or L is a configurable maximum value of the length of the first field specified by a communication protocol; Y values of the first field correspond to Y second-type trigger states.

Optionally, the Y values of the first field include a value c 1, the value c 1 is used to indicate a c th second-type trigger state of the Y second-type trigger states. c 1 is 1 to 2 N one of the values except 0 and the first value in the integer of 0 to 1, and N is a length of the first field.

[0043] In this implementation, for the scheme that the special value of the first field is used to indicate that the terminal device reports the measurement report based on the event trigger, the network device can further activate Y second-type trigger states in the trigger state list. The Y values of the first field correspond to the Y second-type trigger states, thereby facilitating the network device to indicate the second-type trigger state through the value of the first field.

[0044] In a possible implementation of the first aspect or the second aspect, a number of the second type of trigger states in the trigger state list is greater than 2 N -2, N=L.

[0045] In a possible implementation of the first aspect or the second aspect, R values of the first field correspond to the second type of trigger states in the trigger state list configured by the network device for the terminal device, and the second type of trigger states are associated with one or more non-event-triggered reporting configurations. For example, the R values include a dth value, the dth value is used to indicate a dth second type of trigger state in the trigger state list, and the R values are values of the first field except 0 and a first value. R is a number of the second type of trigger states in the trigger state list, and d is an integer greater than or equal to 1 and less than or equal to R. Optionally, the R values include a value d1, and the value d1 is used to indicate the dth second type of trigger state in the trigger state list. d1 is 1 to 2 N -1 except the first value, and N is a length of the first field. The R values of the first field correspond to the second type of trigger states in the trigger state list configured by the network device for the terminal device. Thus, the network device can indicate the second type of trigger state through the value of the first field.

[0046] In a possible implementation of the first aspect or the second aspect, a number of the second type of trigger states in the trigger state list is less than or equal to 2 N -2, and N is a length of the first field.

[0047] In a possible implementation of the first aspect or the second aspect, the first value is X+1, X is a number of the second type of trigger states configured or activated by the network device for the terminal device, and the second type of trigger state is associated with one or more non-event-triggered reporting configurations. In this implementation, the first value is determined in combination with the number of the configured or activated second type of trigger states, so that the network device can indicate, through the value of the first field, that the terminal device reports a measurement report based on an event trigger or a measurement report based on a non-event trigger. The indication overhead is reduced.

[0048] In a possible implementation of the first aspect or the second aspect, X values of the first field correspond to X second type of trigger states configured by the network device for the terminal device. For example, the X values include an e th value, the e th value is used to indicate an e th second type of trigger state in the X second type of trigger states, and e is an integer greater than or equal to 1 and less than or equal to X. Optionally, the X values include a value e1, and the value e1 is used to indicate the e th second type of trigger state in the X second type of trigger states. e1 is 0 to 2 N-1 in addition to the value X+1, N is the length of the first field. It is convenient to realize that the second type of trigger state is indicated by the value of the first field.

[0049] In a possible implementation of the first aspect or the second aspect, the first field is a channel state information request field.

[0050] In a possible implementation of the first aspect, the method further includes: receiving, by the terminal device, first configuration information from the network device, the first configuration information being used to configure one or more first type trigger states, each first type trigger state being associated with one or more event triggered reporting configurations. This is to configure one or more first type trigger states for the terminal device. It is convenient for the network device to indicate the corresponding first type trigger state through the value of the first field in the future.

[0051] In a possible implementation of the second aspect, the method further includes: sending, by the network device, first configuration information to the terminal device, the first configuration information being used to configure one or more first type trigger states, each first type trigger state being associated with one or more event triggered reporting configurations. This is to configure one or more first type trigger states for the terminal device. It is convenient for the network device to indicate the corresponding first type trigger state through the value of the first field in the future.

[0052] In a possible implementation of the first aspect or the second aspect, one of the one or more first type trigger states is associated with one or more event triggered reporting configurations, and the one or more event triggered reporting configurations are associated with the same second uplink resource. In this way, when the event associated with the multiple event triggered reporting configurations occurs, the terminal device sends the second uplink resource. In this way, the network device can determine which first type trigger state corresponds to the event through the second uplink resource.

For example, the fifth generation mobile communication (5th generation, 5G) system, the new radio (new radio, NR) system, the long term evolution (long term evolution, LTE) system, the LTE frequency division duplex (frequency division duplex, FDD) system, the LTE time division duplex (time division duplex, TDD), the universal mobile communication system (universal mobile telecommunication system, UMTS), the future mobile communication system, the vehicle to everything (vehicle to everything, V2X) communication system, the device to device (device to device, D2D) communication system, the Internet of Things communication system, the industrial Internet communication system, or the satellite communication system, etc. The wireless communication system involved in the present application also includes but is not limited to: narrow band Internet of Things system (narrow band-internet of things, NB-IoT).

[0148] The communication system to which the present application is applicable includes terminal devices and network devices. The terminal devices and network devices are introduced as follows.

[0149] A terminal device, also referred to as a UE, a mobile station (MS), a mobile terminal (MT), a fixed wireless access (FWA), a customer premise equipment (CPE), etc. A terminal device is a device including a wireless communication function (providing voice / data connectivity to a user). 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.

[0150] 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.

[0151] 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.

[0152] 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 open RAN (O-RAN or 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.

[0153] 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).

[0154] 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.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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 requiring to meet a relatively short delay requirement in processing time are arranged in the DU, and functions not requiring to meet the delay requirement are arranged in the CU.

[0160] In a possible implementation manner, as shown in FIG. 2, the DU is a logical node carrying an RLC layer, a medium access control (MAC) layer, a 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 PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like.

[0161] In one possible implementation, as shown in FIG. 2, the RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a TRP, a RRH, or other similar functional entity in 3GPP. In some examples, the Low-PHY includes portions of 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.

[0162] The DU and the RU can or can not be co-located. The DU and the RU exchange control plane and user plane information over a front-haul link via a lower-layer split-control, user and synchronization (LLS-CUS) interface. 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 have a lower-layer split management (LLS-M) interface of the front-haul link to exchange management information, and the management plane (M-Plane) refers to non-real-time management operations between the DU and the RU.

[0163] 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 that the DU and the RU have 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.

[0164] 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 this application.

[0165] 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 this 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 this application, and the specific application is not limited.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] In order to facilitate understanding of the technical solutions of the present application, some technical terms related to the present application are introduced below.

[0170] 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 for forming a beam can be beamforming technology or other technology. Beamforming technology can be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources.

[0171] 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 an uplink TCI-state and a downlink TCI-state), or a spatial relation, and the like. 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.

[0172] 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 status information reference signal (CSI-RS), the TCI State, the downlink / joint transmission configuration number state (DLorjointTCI state), the synchronization signal and PBCH block (SS / PBCH block, SSB for short), and the tracking reference signal (TRS) can be replaced with each other.

[0173] 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 number 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.

[0174] 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.

[0175] 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.

[0176] 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 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 transmission configuration indication (TCI) field in downlink control information (DCI).

[0177] 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 regarded as one antenna port set.

[0178] 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 angel-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.

[0179] 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 a suitable 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.

[0180] In the 3GPP protocol, the network device can indicate the TCI state to the terminal device through the TCI field in the 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 identifier ID of a TCI state, which can be any one of identifier, indication, indicator, index, identity, and identification. The ID 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 IDs, which can uniquely identify two TCI states, including a downlink TCI state and an uplink TCI state.

[0181] 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:

[0182] Each TCI state includes its own identifier (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 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 typeD QCL-info. The specific execution steps are as follows:

[0183] 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 best for receiving the reference signal resource, and take the receiving beam as the receiving beam of the reference signal resource.

[0184] 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 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:

[0185] The specific execution steps are as follows:

[0186] 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 by the terminal device. 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.

[0187] The configuration, activation and indication of the TCI state are introduced below.

[0188] 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.

[0189] TCI-state activation: After the network device configures multiple TCI-states, it also needs to activate 8 of them through MAC CE. The 8 TCI-states correspond one-to-one 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.

[0190] 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 channel state information-reference signal (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 the 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, so as to transmit or receive data by using the corresponding beam.

[0191] 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, and ID in this paper can be translated as identifier, indication, indicator, index, identity, or identification. identifier, indication, indicator, index, identity, and identification can be replaced with each other.

[0192] In this application, the reference signal of type QCLtypeD in the TCI state is the reference signal corresponding to the reference signal resource in the typeD QCL information in the TCI state.

[0193] At present, the terminal device and the network device select a suitable beam through a beam management process and communicate through the selected beam. The beam management process includes: first performing beam coarse alignment based on SSB, and then performing beam fine adjustment based on CSI-RS. The beam management process can be divided into three stages, which are introduced as follows.

[0194] Stage one: coarse beam alignment between the network device and the terminal device.

[0195] 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 time instants. Meanwhile, the terminal device sweeps reception beams, that is, the terminal device also receives SSBs from the network device through beams in different directions at different time instants. The terminal device determines a beam for the base station to transmit signals and a 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 a base station beam, and the beam for the terminal device to receive signals is referred to as a terminal beam.

[0196] 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 B15, 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 the corresponding SSB resources using the beam B0, transmits SSBs to the terminal device using the beam B1, and so on, and transmits SSBs to the terminal device using the beam B5. The terminal device measures the SSBs transmitted by the base station through the beams B0 to B5 respectively through the beams U0 to U3 respectively, and obtains measurement results. The terminal device can determine a 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.

[0197] Stage two: base station beam fine adjustment.

[0198] 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 include 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 in the above-mentioned stage one to be the beam U1. 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. 7, 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.

[0199] Stage three: UE beam refinement.

[0200] The base station sends the CSI-RS to the terminal device using the beam S1, while the terminal device determines the better terminal beam in the stage one to be the beam U1, 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. 7, the plurality of second candidate beams include 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.

[0201] 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.

[0202] 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.

[0203] 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 (e.g., 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.

[0204] Aperiodic reporting: when the terminal device receives a trigger instruction 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.

[0205] For aperiodic reporting: the network device configures an aperiodic trigger state list (CSI-AperiodicTriggerStateList) which includes one or more trigger states. Each trigger state can be associated with one or more aperiodic channel state information reports (CSI-reports). Each CSI-report is associated with one or more measurement resource sets, and each measurement resource set can include one or more reference signal resources. The network device can trigger a trigger state by the CSIrequest field of the downlink control information (DCI) (the value of the CSIrequest field is not 0, i.e. the bits in the CSIrequest field are not all 0), that is, trigger the reporting of the CSI-report associated with the trigger state.

[0206] When the number of trigger states configured in the aperiodic trigger state list is greater than When the number of trigger states configured in the aperiodic trigger state list is greater than TS The length of the CSI request field in the DCI can take values of {0, 1, 2, 3, 4, 5, 6}.

[0207] As shown in FIG. 8, the T i The T field in the MAC CE is used to indicate the selection state of the corresponding trigger state in the aperiodic trigger state list. For example, the T0 field corresponds to the first trigger state in the aperiodic trigger state list, the T1 field corresponds to the second trigger state in the aperiodic trigger state list, and so on. That is, the T i The T field indicates the i+1th trigger state in the aperiodic trigger state list. When the value of the T i When the value of the T field is 1, it means that the i+1th trigger state is activated, and the i+1th trigger state can be mapped to the value i+1 of the CSI request field in the DCI. According to the communication protocol, the maximum number of trigger states that can be mapped to the CSI request field in the DCI is

[0208] When the number of trigger states configured in the aperiodic trigger state list is less than or equal to In some cases, the CSI request field in the DCI directly indicates one triggering state from the list of aperiodic triggering states. For example, if the CSI request field in the DCI has a value of 1, it indicates the first triggering state in the list of aperiodic triggering states; if the CSI request field in the DCI has a value of 2, it indicates the second triggering state in the list of aperiodic triggering states; and so on.

[0209] For semi-persistent reporting through PUSCH, the network device configures a semi-persistent triggering state list based on PUSCH (semiPersistentOnPUSCH-TriggerStateList), which includes one or more triggering states. Each triggering state can be associated with one or more semi-persistent CSI reports reported through PUSCH, and each CSI report is associated with one or more sets of measurement resources. The network device indicates a triggering state through the CSI request field in the DCI, thereby triggering the reporting of the CSI report associated with the triggering state. Here, the DCI is scrambled by the SP-CSI-RNTI, and when the CSI request field of the DCI has a value of 0, it indicates the first triggering state in the semi-persistent triggering state list based on PUSCH.

[0210] For semi-persistent reporting through PUCCH, the network device directly activates one or more semi-persistent CSI reports reported through PUCCH through a MAC CE.

[0211] In this application, the event-triggered reporting mode includes Mode A (Mode A) and Mode B (Mode B). That is, the terminal device can report measurement results through Mode A or Mode B. This application mainly relates to Mode A. Mode A is introduced below. It should be noted that Mode A can also have other names, which are not limited in this application.

[0212] I. Mode A includes the following steps a to c.

[0213] Step a: the terminal device sends first uplink signaling to the network device. Correspondingly, the network device receives the first uplink signaling from the terminal device.

[0214] The first uplink signaling is used to request the network device to schedule the second uplink signaling. Alternatively, the first uplink signaling is used to request the network device to schedule the first uplink resource for the terminal device. Alternatively, the first uplink signaling is used to indicate to the network device that the measurement result triggered by the event needs to be reported. Alternatively, the first uplink signaling is used to indicate that the event occurs. Alternatively, the first uplink signaling is used to request the network device to schedule the uplink resource for carrying the measurement report triggered by the event. The specific application is not limited.

[0215] Optionally, when the event occurs, the occurrence condition of the event is met, or the measurement report triggered by the event needs to be reported, the terminal device sends the first uplink signaling.

[0216] The first uplink signaling is PUCCH signaling. For example, the first uplink signaling is uplink control information (UCI) signaling or MAC CE signaling.

[0217] Optionally, the first uplink signaling is sent through the second uplink resource. The second uplink resource is a reporting indication resource or a scheduling request resource. For example, as shown in FIG. 9, the terminal device sends the first uplink signaling through the second uplink resource. That is, the second uplink resource is used to carry the first uplink signaling.

[0218] Step b: The network device sends a scheduling signaling to the terminal device. Correspondingly, the terminal device receives the scheduling signaling from the network device.

[0219] The scheduling signaling is used to schedule the sending of the second uplink signaling. Alternatively, the scheduling signaling is used to indicate or schedule the first uplink resource. For example, as shown in FIG. 9, the network device sends the scheduling signaling to the terminal device.

[0220] Optionally, the scheduling signaling is an uplink scheduling signaling used to schedule PUSCH for the terminal device. That is, the first uplink resource is a PUSCH resource.

[0221] Optionally, the scheduling signaling is a downlink scheduling signaling used to schedule PUCCH for the terminal device. That is, the first uplink resource is a PUCCH resource.

[0222] Optionally, the scheduling signaling is DCI.

[0223] Optionally, the scheduling signaling can be any one or more of DCI format 0_1, DCI format 0_2, and DCI format 0_3.

[0224] Step c: The terminal device sends the second uplink signaling to the network device. Correspondingly, the network device receives the second uplink signaling from the terminal device.

[0225] The second uplink signaling is used to carry an event-triggered measurement report or event-related measurement report. Optionally, the second uplink signaling is PUSCH signaling or PUCCH signaling.

[0226] Optionally, the second uplink signaling is carried on the first uplink resource. The first uplink resource is a reporting resource. As shown in FIG. 9, the terminal device sends the second uplink signaling through the first uplink resource. Optionally, the reporting resource is any one of a PUCCH resource, a PUSCH resource, an event-triggered reporting resource, a UE-triggered reporting resource, an event-triggered channel resource, a UE-triggered beam reporting resource, an event-triggered beam reporting resource, an event-triggered uplink resource, a dynamically scheduled PUSCH resource, a non-periodic PUSCH resource, a semi-persistent PUCCH resource, and a semi-persistent PUSCH resource, and the specific embodiments are not limited herein.

[0227] Before R18 and before R18, the terminal device measurement result reporting process is dominated by the network device, that is, the network device decides when the terminal device reports the measurement result. This method results in a large uplink resource overhead. Specifically, in periodic reporting and semi-persistent reporting, the terminal device needs to report the measurement result 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), thus causing waste of uplink resources. In release 19 (R19), UE or event-triggered reporting methods are introduced. The terminal device can report the event-related beam measurement result. Therefore, how to trigger the measurement result reporting is a problem worth considering.

[0228] The present application provides corresponding technical solutions, which can be specifically understood by referring to the related descriptions in the embodiments below, and thus will not be described herein.

[0229] 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 information report, or an event related to a terminal device initiated report (or measurement result information) after active measurement, or a specific condition related to a terminal device initiated measurement result information report. For example, the terminal device can actively perform measurement (such as beam measurement, or channel measurement, etc.), and then obtain measurement result information related to the event. For another example, the terminal device can perform measurement based on a reference signal according to a configuration of a reference signal resource, and then obtain measurement result information related to the event. For another example, the terminal device actively performs measurement, and reports measurement result information related to the event when a specific condition is met. 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 is not limited in the embodiments of this application.

[0231] In the present application, the event-triggered reporting configuration can be a channel status information reporting configuration (CSI-reportConfig). The event-triggered reporting configuration includes an indication information, which is used to indicate that the event-triggered reporting configuration is a configuration of event-triggered reporting, or is used to indicate that the event-triggered reporting configuration contains event-related information, such as an index of the event, threshold value information corresponding to the event, i.e., a threshold value involved in the event definition. Alternatively, the event-triggered reporting configuration is configured by a dedicated information element, such as L1-EventTriggered-CSI-ReportConfig or UEInitiated-CSI-ReportConfig. Optionally, the event-triggered reporting configuration includes one or more of the following:

[0232] 1. One or more reference signal resources. The one or more reference signal resources are used for channel measurement, interference measurement, or beam management. The one or more reference signal resources can be located in one or more reference signal resource sets.

[0233] 2, cell information; used to indicate the cell corresponding to the one or more reference signal resources, and / or the cell corresponding to the reference signal resource used to monitor whether the event occurs. For example, the cell information includes the index or identity of the serving cell.

[0234] 3, the event triggering reporting configuration includes mode A.

[0235] 4, reporting slot offset information, used to indicate the time slot offset value of the reporting resource and the scheduling signaling.

[0236] 5, the information of one or more events. For example, the index of one or more events, or an event table including the one or more events.

[0237] 6, reporting indication resource, used to carry the indication information indicating the occurrence of the event. The indication information is used to indicate to the network device that the event triggered measurement report needs to be reported, or to indicate that there is an event occurrence, or to request to schedule the reporting resource for carrying the event triggered measurement report, or to indicate the demand for reporting the event triggered measurement report on the reporting resource associated with the reporting indication resource. For example, the second uplink resource described above.

[0238] The event triggered reporting configuration can also be called event triggered report configuration, event reporting configuration, report reporting configuration, UE triggered reporting configuration, UE triggered CSI report configuration, UE initiated reporting configuration, UE initiated CSI report configuration, or reporting configuration, etc. The specific name of the event triggered reporting configuration is not limited in the present application.

[0239] The reporting indication resource can be replaced by PUCCH indication resource, PUSCH indication resource, scheduling request resource, pre-indication resource, pre-notification resource, event triggered reporting scheduling request resource, UE triggered reporting scheduling request resource, first channel resource of UE or event triggered reporting, first uplink resource of UE or event triggered reporting, reporting request resource of UE triggered beam reporting, reporting indication resource of UE triggered beam reporting, first PUCCH resource of UE triggered reporting, or UE triggered reporting scheduling request resource.

[0240] The reporting resource can be alternatively described as a PUCCH resource, a PUSCH resource, an event-triggered reporting resource, a UE-triggered reporting resource, a second channel resource triggered by the UE or an event, a second uplink resource triggered by the UE or an event, a UE-triggered beam reporting reporting resource, or an event-triggered beam reporting reporting resource. The reporting resource can be a periodic PUCCH resource, an aperiodic PUSCH resource, a semi-persistent PUCCH resource, a semi-persistent PUSCH resource, a configured grant PUSCH (e.g., a configured grant Type 1 or Type 2 PUSCH), or a dynamically scheduled PUSCH resource (e.g., a PUSCH dynamically scheduled by DCI), etc.

[0241] In this application, the non-event-triggered reporting configuration can be referred to as a channel state information reporting configuration (CSI-ReportConfig), a conventional CSI reporting, a CSI reporting configured by a CSI-ReportConfig, a CSI reporting triggered or configured by a network device, a channel state information reporting configuration (LTM-CSI-ReportConfig) configured for mobility triggered by layer 1 / layer 2, a CSI reporting without event information, a CSI reporting without event-related information in a CSI-ReportConfig, or a CSI reporting without event information. The specific application is not limited. The non-event-triggered reporting configuration can also be referred to as a non-event-triggered reporting configuration, a transmission CSI reporting, or a CSI reporting without event information, etc. The specific application is not limited.

[0242] In this application, the event-triggered measurement reporting can also be referred to as an event-triggered reporting, an event-triggered reporting, an event-triggered CSI reporting, an event-triggered CSI measurement reporting, an event-triggered beam reporting, an event-triggered beam measurement reporting, an event-triggered measurement reporting, an event-triggered beam reporting, an event-triggered beam measurement result reporting, an event-triggered measurement result reporting, or an event-triggered interference measurement reporting. The specific application is not limited. The event triggering can be referred to as terminal initiated or UE triggered (UE initiated).

[0243] In this application, the serving beam can also be referred to as: a 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, etc. The specific application is not limited. 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, etc. The specific application is not limited.

[0244] In this application, the concepts of cell, serving cell, component carrier (CC), and the like can be replaced with each other. The serving cell can be a primary cell (Pcell), a secondary cell (Scell), or a primary secondary cell (PScell). The cell of the primary component carrier (PCC) can be referred to as the Pcell, and the cell of the secondary component carrier (SCC) can be referred to as the Scell. In addition, the cell can also be a neighboring cell of the serving cell (such as a cell corresponding to an additional physical cell identifier (additional PCI), a candidate cell, and the like.

[0245] In this application, if a TCI state is a downlink TCI state or a common state, the QCL type D reference signal in the TCI state can be understood as the reference signal corresponding to the reference signal resource in the typeD QCL information in the TCI state. The QCL resource in the TCI state can be understood as the reference signal resource in the typeD QCL information in the TCI state. If a TCI state is an uplink TCI state, the reference signal in the TCI state refers to the reference signal configured in the TCI state. For example, the reference signal configured in ssb-Index-r17, csi-RS-Index-r17, or srs-r17 in the structure of the above uplink TCI state. The reference signal can be a CSI-RS, an SRS, or an SSB.

[0246] For a downlink TCI state or a common TCI state, the reference signal associated with the QCL TypeD reference signal of the TCI state: an SSB having a QCL relationship with the QCL TypeD reference signal. The SSB is an SSB corresponding to a source QCL resource of a QCL chain. That is, the source QCL resource is an SSB resource. The QCL chain is determined according to the QCL TypeD reference signal of the TCI state. For example, the QCL resource of 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 TRS resource. The TCI state corresponding to the CSI-RS resource can be understood as the TCI state adopted by the network device to send the CSI-RS resource, or the TCI state adopted by the network device to send the 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 the TCI state adopted by the network device to send the TRS resource, or the TCI state adopted by the network device to send the TRS corresponding to the TRS. As can be seen, the QCL resource (such as a CSI-RS resource) in the TCI state indicated by the network device for the terminal device, the QCL resource (such as a TRS resource) in the TCI state corresponding to the CSI-RS resource, and the QCL resource (such as an SSB resource) in the TCI state corresponding to the TRS resource constitute a QCL chain. The source QCL resource of the QCL chain is an SSB resource, so the reference signal associated with the QCL TypeD reference signal of the TCI state is the SSB corresponding to the SSB resource.

[0247] The reference signal associated with the reference signal in the uplink TCI state: the SSB having a QCL relationship with the reference signal in the uplink TCI state. The SSB is the SSB corresponding to the source QCL resource of the QCL chain. That is, the source QCL resource is an SSB resource. The QCL chain is determined according to the reference signal in the TCI state. For example, the network device indicates the reference signal in the uplink TCI state for the terminal device to be a CSI-RS. The QCL resource in the TCI state corresponding to the CSI-RS resource adopted by the CSI-RS is a TRS resource. The TCI state corresponding to the CSI-RS resource can be understood as the TCI state adopted by the network device to send the CSI-RS resource, or the TCI state adopted by the network device to send the CSI-RS corresponding to the CSI-RS resource. 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 the TCI state adopted by the network device to send the TRS resource, or the TCI state adopted by the network device to send the TRS corresponding to the TRS resource. As can be seen, the reference signal resource (such as the CSI-RS resource) corresponding to the reference signal in the uplink TCI state indicated by the network device for the terminal device, the QCL resource (such as the TRS resource) in the TCI state corresponding to the CSI-RS resource, and the QCL resource (such as the SSB resource) in the TCI state corresponding to the TRS resource form a QCL chain. The source QCL resource of the QCL chain is an SSB resource, so the reference signal associated with the reference signal in the TCI state is the SSB corresponding to the SSB resource. For another example, the network device indicates the reference signal in the uplink TCI state for the terminal device to be an SRS. The QCL resource in the TCI state corresponding to the SRS resource adopted by the SRS is an SSB resource. The TCI state corresponding to the SRS resource can be understood as the TCI state adopted by the terminal device to send the SRS resource, or the TCI state adopted by the terminal device to send the SRS corresponding to the SRS resource. The reference signal resource in the TCI state corresponding to the SRS resource is an SSB resource. As can be seen, the reference signal resource (such as the SRS resource) corresponding to the reference signal in the uplink TCI state indicated by the network device for the terminal device, and the reference signal resource (such as the SSB resource) in the TCI state corresponding to the SRS resource form a QCL chain. The source QCL resource of the QCL chain is an SSB resource, so the reference signal associated with the reference signal in the TCI state is the SSB corresponding to the SSB resource.

[0248] The technical solutions of the present application will be described below in conjunction with specific embodiments.

[0249] FIG. 10 is a schematic diagram of one embodiment of the measurement report sending method and the measurement report receiving method of the present application. Please refer to FIG. 10, the method comprises:

[0250] 1001、The network device sends scheduling signaling to the terminal device. Correspondingly, the terminal device receives the scheduling signaling from the network device.

[0251] The scheduling signaling is used for scheduling the first uplink resource. The scheduling signaling comprises first indication information. The first indication information is used for determining that the first uplink resource is used for carrying the measurement report based on the event triggering. Alternatively, the first indication information is used for indicating that the first uplink resource is used for carrying the measurement report based on the event triggering. In other words, the scheduling signaling is used for scheduling the reporting of the measurement report based on the event triggering.

[0252] It should be noted that the implementation mode in which the first indication information is carried in the scheduling signaling is shown in the above step 1001. In actual application, the network device can also send the first indication information to the terminal device through independent signaling. The specific implementation is not limited in the present application.

[0253] Optionally, the scheduling signaling comprises a first field, and the first indication information is carried in the first field.

[0254] Optionally, the scheduling signaling is carried in DCI, and the first field is a CSI request field in the DCI.

[0255] Optionally, the scheduling signaling is carried in any one or more of DCI format 0_1, DCI format 0_2 and DCI format 0_3.

[0256] Optionally, the length of the first field is N. The length of the first field can be understood as the number of bits included in the first field, or the bit width of the first field. The value of N can be 0, 1, 2, 3, 4, 5 or 6, and the specific implementation is not limited in the present application. Optionally, the value of N can be configured by the network device, or be specified by the communication protocol, or be predefined, and the specific implementation is not limited in the present application. For example, the network device configures the value of N through a high-level parameter (for example, reportTriggerSize or (reportTriggerSizeDCI-0-2).

[0257] Some possible implementation modes of the first field are introduced below. The present application is still applicable to other implementation modes, and the specific implementation is not limited in the present application.

[0258] Implementation mode 1: The first field indicates a first type of trigger state. The first type of trigger state is associated with one or more event-triggered reporting configurations. In other words, the first type of trigger state refers to the trigger state associated with the event-triggered reporting configuration. The name of the first type of trigger state is not limited in the present application.

[0259] Optionally, the list of trigger states of the terminal device comprises one or more trigger states. The list of trigger states comprises the first type of trigger state and / or the second type of trigger state. The second type of trigger state is associated with one or more non-event triggered reporting configurations. In other words, the second type of trigger state refers to the trigger state associated with the non-event triggered reporting configuration. The name of the second type of trigger state is not limited in the present application. In the embodiment, the list of trigger states comprises one or more first type of trigger states and / or one or more second type of trigger states.

[0260] The following describes some possible schemes in the implementation manner 1 in combination with the number of trigger states included in the list of trigger states.

[0261] Implementation manner 1: the number of trigger states in the list of trigger states is greater than 2 N -1. Optionally, before the step 1001, the method further comprises the step 1101 in the embodiment shown in FIG. 11.

[0262] 1101. The network device sends the first activation signaling to the terminal device. Correspondingly, the terminal device receives the first activation signaling from the network device.

[0263] The first activation signaling is used to activate or select one or more trigger states in the list of trigger states. The activated or selected one or more trigger states comprises the first type of trigger state indicated by the first field. In other words, the first type of trigger state indicated by the first field is one of the trigger states in the first activation signaling. The activated or selected one or more trigger states is part of the trigger states in the list of trigger states. Optionally, the first activation signaling activates at most 2 N trigger states.

[0264] Optionally, the one or more trigger states comprises the i+1th trigger state in the list of trigger states, and the i+1th trigger state corresponds to the Ti field in the first activation signaling. The value of the Ti field is 1, and i is an integer greater than or equal to 0.

[0265] Specifically, each trigger state in the list of trigger states corresponds to a T field in the first activation signaling. For example, the first trigger state in the list of trigger states (i.e., the trigger state with the first position in the list of trigger states) corresponds to the T0 field in the first activation signaling, the second trigger state (i.e., the trigger state with the second position in the list of trigger states) corresponds to the T1 field in the first activation signaling, and so on. In other words, if a trigger state corresponds to the T field in the first activation signaling, then i the trigger state is located at the i+1th position in the list of trigger states. T i The T field is used to indicate the selection or activation state of the i+1th trigger state in the list of trigger states. When the Ti When the value of the T field is 1, it indicates that the i+1th trigger state is activated or selected. When the value of the T field is 0, it indicates that the i+1th trigger state is not activated or selected. i It is to be noted that when the value of i is greater than the number of trigger states in the trigger state list, the terminal device ignores the T field in the first activation signaling. i

[0266] The above is only an example. In actual applications, the value of the T field and the corresponding indication meaning can be different, which is not limited in the present application. For example, when the value of the T field is 0, it indicates that the i+1th trigger state is activated. When the value of the T field is 1, it indicates that the i+1th trigger state is not activated. i The above is only an example. In actual applications, the value of the T field and the corresponding indication meaning can be different, which is not limited in the present application. For example, when the value of the T field is 0, it indicates that the i+1th trigger state is activated. When the value of the T field is 1, it indicates that the i+1th trigger state is not activated. i The above is only an example. In actual applications, the value of the T field and the corresponding indication meaning can be different, which is not limited in the present application. For example, when the value of the T field is 0, it indicates that the i+1th trigger state is activated. When the value of the T field is 1, it indicates that the i+1th trigger state is not activated. i The above is only an example. In actual applications, the value of the T field and the corresponding indication meaning can be different, which is not limited in the present application. For example, when the value of the T field is 0, it indicates that the i+1th trigger state is activated. When the value of the T field is 1, it indicates that the i+1th trigger state is not activated.

[0267] In one possible implementation, the activated or selected one or more trigger states include at least one first type of trigger state. In another possible implementation, the communication protocol specifies that the activated or selected one or more trigger states include at least one first type of trigger state.

[0268] Specifically, after the first activation signaling takes effect, the terminal device performs event-triggered beam management, or in other words, the terminal device measures the reference signal resource in the event-triggered reporting configuration associated with the activated at least one first type of trigger state. Furthermore, if an event occurs, the terminal device sends second indication information to the network device. The second indication information is used to indicate that an event occurs or that a measurement report based on event triggering needs to be reported. The second indication information can be carried in the first uplink signaling in step a in the above mode A.

[0269] Specifically, only one first type of trigger state is configured in the trigger state list. The first type of trigger state is associated with all event-triggered reporting configurations of all cells of the terminal device. Therefore, the terminal device performs event-triggered beam management only when the first type of trigger state is activated by the first activation signaling, or the terminal device measures the reference signal resource in the event-triggered reporting configuration associated with the first type of trigger state only when the first type of trigger state is activated by the first activation signaling. The value of the T field in the first activation signaling corresponding to the first type of trigger state is 1, indicating that the first type of trigger state is activated.

[0270] ​Optionally, the first activation signaling activates or selects one or more trigger states in the trigger state list. The one or more trigger states include M trigger states. The M trigger states are associated with all event-triggered reporting configurations of the first cell of the terminal device. The terminal device performs the beam management of the event-triggering of the first cell only when the first activation signaling activates the M trigger states. Or the terminal device measures the reference signal resource in the event-triggered reporting configuration associated with the M trigger states only when the first activation signaling activates the M trigger states. The value of the T field in the first activation signaling corresponding to the M trigger states is 1, indicating that the M trigger states are activated. The first cell is the cell to which the trigger state list belongs.

[0271] Optionally, the validity time of the first activation signaling is a first time length after the terminal device sends a PUCCH carrying hybrid automatic repeat request-acknowledge (HARQ-ACK) information. The HARQ-ACK information is feedback information of the first activation signaling. Optionally, the first time length can be determined by one or more of network configuration, terminal device reporting, and communication protocol specification. Optionally, the unit of the first time length can be millisecond, microsecond, time slot, symbol, etc.

[0272] Optionally, the one or more trigger states activated or selected by the first activation signaling include M trigger states. The M values of the first field correspond to the M trigger states. The M values include the fth value, and the fth value is used to indicate the fth trigger state in the M trigger states. f is an integer greater than or equal to 1 and less than or equal to M. M is an integer greater than or equal to 1 and less than or equal to 2 N -1. Optionally, the M values of the first field do not include the value 0.

[0273] For example, the M values include the jth value, and the jth value is used to indicate the jth trigger state in the M trigger states. j is an integer greater than or equal to 1 and less than or equal to M. For example, the jth value is the value j1, and the value j1 is used to indicate the jth trigger state in the M trigger states. j1 is an integer greater than or equal to 1 and less than or equal to 2 N -1. In this implementation manner, for example, the M values include 1 to M, the value 1 is used to indicate the first trigger state in the M trigger states, the value 2 is used to indicate the second trigger state in the M trigger states, and so on, and the value M is used to indicate the Mth trigger state in the M trigger states. For example, the M trigger states include 2 N -1 trigger states. The M values of the first field are 1 to 2 N -1. The 2 N -1 trigger states correspond to the 2 N -1 values of the first field. The value 1 is used to indicate the 2 N- the first one of the M trigger states, with a value of 2 indicating that trigger state 2 N - the second one of the M trigger states, and so on, with a value of M indicating that trigger state M N - the last one of the M trigger states.

[0274] Optionally, the M trigger states are sorted in an order from front to back or from back to front according to an activation order of the trigger states in the first activation signaling. The activation order of the trigger states can be an order of the T fields corresponding to the trigger states in the first activation signaling. For example, as shown in FIG. 8, the T0 field, the T2 field, and the T 10 field respectively correspond to a value of 1, the T0 field indicates that trigger state 1 is activated, the T2 field indicates that trigger state 2 is activated, and the T 10 field indicates that trigger state 10 is activated. The T0 field is the first T field with a value of 1 in the first activation signaling, the T2 field is the second T field with a value of 1 in the first activation signaling, and the T 10 field is the third T field with a value of 1 in the first activation signaling. That is, the M trigger states are sorted as: trigger state 1-trigger state 2-trigger state 10.

[0275] The value of the first field is one of the M values, and the value is used to indicate a first type of trigger state.

[0276] It should be noted that if the trigger states activated by the first activation signaling do not include the first type of trigger state, the terminal device does not perform event-triggered beam management, or in other words, the terminal device does not measure the reference signal resource associated with the event-triggered reporting configuration; or in other words, the terminal device does not initiate the second indication information, or in other words, the terminal device does not send a measurement report based on event triggering.

[0277] In another possible implementation, the activated or selected one or more trigger states include all the first type of trigger states in the trigger state list. In other words, the activated or selected one or more trigger states include all the first type of trigger states configured by the network device for the terminal device. Each first type of trigger state corresponds to a Ti field in the first activation signaling, and the value of the Ti field is 1. That is, the value of the Ti field in the first activation signaling corresponding to each first type of trigger state of all the first type of trigger states configured by the network device for the terminal device is set to 1.

[0278] Optionally, if the network device configures K first-type trigger states for the terminal device, that is, the trigger state list includes K first-type trigger states, where K is an integer greater than or equal to 1, the communication protocol specifies or the network device configures the K values ​​of the first field to map to these K first-type trigger states. The specific correspondence between the K values ​​of the first field and these K first-type trigger states is similar to the correspondence between the K values ​​of the first field and the K first-type trigger states in the trigger state list in the second implementation method described later. For details, please refer to the relevant introduction below.

[0279] Optionally, if the network device configures K first-type trigger states for the terminal device (i.e., the trigger state list includes K first-type trigger states, where K is an integer greater than or equal to 1), or if the network device activates K first-type trigger states for the terminal device, the communication protocol specifies or the network device configures a value of the first field to map to these K first-type trigger states. For example, the value of the first field is 2. N -1 is one of the possible values. For example, the first field can have a value of 1 or 2. N -1, the first field indicates the K first-class trigger states.

[0280] Optionally, if the network device configures K first-type trigger states for the terminal device, the first activation signaling activates K+U trigger states, which include the K first-type trigger states and U second-type trigger states. Each of the K+U trigger states corresponds to a Ti field in the first activation signaling, and the value of the Ti field is 1, indicating that the trigger state is activated.

[0281] The 2 in the first field N K values ​​from the -1 possible values ​​correspond to K first-type trigger states. If a first trigger state is the trigger state indicated by the Ti field (set to 1) of the a1th value in the first activation signaling, then if the value of the first field is a1, it indicates that the first trigger state is indicated by the first field. For example, the first activation signaling activates three first-type trigger states and four second-type trigger states, where the T1 field in the first activation signaling indicates second-type trigger state 1, the T4 field in the first activation signaling indicates first-type trigger state 1, the T5 field in the first activation signaling indicates second-type trigger state 2, and the T... 10 The field indicates the first type of trigger state 2, T in the first activation signaling. 13 The field indicates the first type of trigger state 3, T in the first activation signaling. 21 The field indicates the second type of trigger state 3, T in the first activation signaling. 23The field indicates the second type of trigger state 4. Therefore, the K values of the first field are 1 to 7, and when the value of the first field is 4, it is known that the first type of trigger state indicated by the first field is T 10 The field indicates the first type of trigger state 2. That is, the trigger state indicated by the fourth 1 -set Ti field in the first activation signaling.

[0282] Optionally, one or more first type of trigger states in the trigger state list of the terminal device can be pre-configured, or pre-defined, or configured by the network device, which is not limited in the present application. Optionally, the embodiment shown in FIG. 11 further includes step 1101a. Step 1101a can be performed before step 1101.

[0283] 1101a. The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0284] The first configuration information is used to configure one or more first type of trigger states. Each first type of trigger state is associated with one or more event trigger reporting configurations.

[0285] Optionally, the one or more first type of trigger states can be located in a trigger state list. For example, aperiodic trigger state list (for example, CSI-aperiodicTriggerStateList) or PUSCH-based semi-static trigger state list (for example, semiPersistentOnPUSCH-TriggerStateList). If the one or more first type of trigger states are located in the aperiodic trigger state list, they can be called aperiodic first type of trigger states, and if the one or more first type of trigger states are located in the PUSCH-based semi-static trigger state list, they can be called semi-persistent first type of trigger states.

[0286] Optionally, the trigger state list can include one or more second type of trigger states. If the second type of trigger state is located in the aperiodic trigger state list, it can be called an aperiodic second type of trigger state. If the second type of trigger state is located in the PUSCH-based semi-static trigger state list, it can be called a semi-persistent second type of trigger state.

[0287] In a possible implementation, the trigger state list includes a first type of trigger state, and the first type of trigger state is associated with event trigger reporting configuration of all cells of the terminal device. Optionally, the event trigger reporting configuration is in mode A, and the first type of trigger state is associated with all event trigger reporting configurations in mode A of all cells of the terminal device. Optionally, the first type of trigger state is located at the first position or the last position in the trigger state list. Optionally, the trigger state list is a trigger state list of a primary cell or a secondary primary cell.

[0288] In a possible implementation, the trigger state list includes a plurality of first type of trigger states, and one of the plurality of first type of trigger states is associated with event trigger reporting configuration of a plurality of cells of the terminal device. Optionally, the event trigger reporting configuration is in mode A, and the first type of trigger state is associated with event trigger reporting configuration in mode A of the plurality of cells of the terminal device.

[0289] In another possible implementation, the trigger state list includes a first type of trigger state, and the first type of trigger state is associated with all event trigger reporting configurations of a first cell of the terminal device. The first cell is one cell of the terminal device. For example, the first cell can be a serving cell or a candidate cell, which is not limited in the present application. Optionally, the event trigger reporting configuration is in mode A, and the first type of trigger state is associated with all event trigger reporting configurations in mode A of the first cell of the terminal device. Optionally, the first type of trigger state is located at the first position or the last position in the trigger state list. Optionally, the first cell is a cell to which the trigger state list belongs.

[0290] In another possible implementation, the trigger state list includes a plurality of first type of trigger states, and each of the plurality of first type of trigger states is associated with one or more event trigger reporting configurations of a first cell of the terminal device. The first cell is one cell of the terminal device. For example, the first cell can be a serving cell or a candidate cell, which is not limited in the present application. Optionally, the event trigger reporting configuration is in mode A, and the first type of trigger state is associated with one or more event trigger reporting configurations in mode A of the first cell of the terminal device. Optionally, the first cell is a cell to which the trigger state list belongs.

[0291] Optionally, the trigger state list is an aperiodic trigger state list.

[0292] The first configuration information is used for configuring one or more first-type trigger states. Each first-type trigger state is associated with one or more event triggered reporting configurations. Each event triggered reporting configuration is associated with a second uplink resource. Optionally, the event triggered reporting manner of the event triggered reporting configuration is mode A. One or more of the following restrictions are met:

[0293] Restriction one: one or more event triggered reporting configurations associated with a same second uplink resource are associated with a same first-type trigger state. For example, the second uplink resource #1 is associated with V1 event triggered reporting configurations, which are event triggered reporting configuration #1, event triggered reporting configuration #2, …, and event triggered reporting configuration #V1. The V1 event triggered reporting configurations must be associated with a same first-type trigger state. In other words, the terminal device does not expect that multiple event triggered reporting configurations associated with a same second uplink resource are associated with different first-type trigger states. If at least one event triggered reporting configuration in the first-type trigger state has an event occurrence, the terminal device sends second indication information through the second uplink resource.

[0294] Restriction two: one or more event triggered reporting configurations associated with a same first-type trigger state are associated with a same second uplink resource. For example, the first-type trigger state #1 is associated with V2 event triggered reporting configurations, which are event triggered reporting configuration #1, event triggered reporting configuration #2, …, and event triggered reporting configuration #V2. The V2 event triggered reporting configurations must be associated with a same second uplink resource. In other words, the terminal device does not expect that multiple event triggered reporting configurations associated with a same first-type trigger state are associated with different second uplink resources. In other words, the terminal device does not expect that different second uplink resources are associated with a same first-type trigger state. If at least one event triggered reporting configuration in the first-type trigger state has an event occurrence, the terminal device sends second indication information through the second uplink resource. In other words, one or more event triggered reporting configurations associated with different second uplink resources cannot be associated with a same first-type trigger state, or in other words, the terminal device does not expect that one or more event triggered reporting configurations associated with different second uplink resources are associated with a same first-type trigger state.

[0295] Limitation 3: One or more event triggered reporting configurations associated with different first type trigger states are associated with different second uplink resources. For example, first type trigger state #1 is associated with V2 event triggered reporting configurations, which are event triggered reporting configuration #1, event triggered reporting configuration #2, …, event triggered reporting configuration #V2, respectively. The V2 event triggered reporting configurations are all associated with second uplink resource #1. First type trigger state #2 is associated with V3 event triggered reporting configurations, which are event triggered reporting configuration #1, event triggered reporting configuration #2, …, event triggered reporting configuration #V3, respectively. The V3 event triggered reporting configurations are all associated with second uplink resource #2. It can be seen that second uplink resource #1 and second uplink resource #2 are different. In other words, the terminal device does not expect one or more event triggered reporting configurations associated with different first type trigger states to be associated with the same second uplink resource. In other words, the terminal device does not expect different first type trigger states to be associated with the same second uplink resource. If at least one event triggered reporting configuration in a first type trigger state has an event occurrence, the terminal device sends second indication information through the second uplink resource corresponding to the first trigger state.

[0296] Optionally, the terminal device does not expect an event triggered reporting configuration associated with association mode A and an event triggered reporting configuration associated with association mode B to be associated with the same first uplink resource. Optionally, the terminal device does not expect to be configured with an event triggered reporting configuration associated with association mode A and an event triggered reporting configuration associated with association mode B at the same time.

[0297] Implementation manner two: K values of the first field correspond to K first type trigger states in the trigger state list. For example, the K values of the first field correspond to the K first type trigger states in the trigger state list in ascending order or descending order. The K first type trigger states can be the first K first type trigger states in the trigger state list. The K values include the a-th value, and the a-th value is used to indicate the a-th first type trigger state. The a-th first type trigger state includes the first type trigger state indicated by the first field. K is an integer greater than or equal to 1, and a is an integer greater than or equal to 1 and less than or equal to K. The value of the first field is one of the K values. Optionally, the K values of the first field do not include the value 0.

[0298] According to the communication protocol, the first type of trigger state in the trigger state list is activated without the activation signaling, and the value of the first field can be directly mapped to the K first type of trigger states in the trigger state list. That is, the K first type of trigger states are activated by default. Optionally, the K first type of trigger states can be the first K first type of trigger states in the trigger state list (i.e., the first first type of trigger state to the Kth first type of trigger state in the trigger state list). The K values of the first field correspond to the K first type of trigger states in the trigger state list, or the K values of the first field are mapped to the K first type of trigger states in the trigger state list. For example, the first value of the first field is mapped to the first first type of trigger state of the K first type of trigger states, the second value of the first field is mapped to the second first type of trigger state of the K first type of trigger states, and so on, and the Kth value of the first field is mapped to the Kth first type of trigger state of the K first type of trigger states. For another example, the first value of the first field is mapped to the Kth first type of trigger state of the K first type of trigger states, the second value of the first field is mapped to the K-1th first type of trigger state of the K first type of trigger states, and so on, and the Kth value of the first field is mapped to the first first type of trigger state of the K first type of trigger states.

[0299] Optionally, the K values of the first field are 1 to K. The value 1 is used to indicate the first first type of trigger state of the K first type of trigger states, the value 2 is used to indicate the second first type of trigger state of the K first type of trigger states, and so on, and the value K is used to indicate the Kth first type of trigger state of the K first type of trigger states.

[0300] Optionally, the K values of the first field are 2 N to K. N 1, the value 2 N K is used to indicate the first first type of trigger state of the K first type of trigger states, the value 2 N K+1 is used to indicate the second first type of trigger state of the K first type of trigger states, and so on, and the value 2 N 1 is used to indicate the Kth first type of trigger state of the K first type of trigger states.

[0301] Optionally, only one first type of trigger state is configured in the trigger state list, and the first type of trigger state is associated with the event trigger reporting configuration of multiple cells, or the first type of trigger state is associated with all event trigger reporting configurations of all cells of the terminal device. Then the first type of trigger state is mapped to the value 2 N -1 or 1 of the first field by default. That is, when the value of the first field is 2 N -1 or 1, the first type of trigger state is indicated.

[0302] Optionally, only one first type of trigger state is configured in the trigger state list, and the first type of trigger state is associated with all event trigger reporting configurations of the first cell. The first cell is one cell of the terminal device. For example, the first cell can be a serving cell or a candidate cell, which is not limited in the present application. The first type of trigger state is mapped to the value 2 of the first field by default N -1 or 1. That is, when the value of the first field is 2 N -1 or 1, the first type of trigger state is indicated. Optionally, the first cell is the cell to which the trigger state list belongs.

[0303] Optionally, before step 1001, step 1201 in the embodiment shown in FIG. 12 is further included.

[0304] 1201. The network device sends second activation signaling to the terminal device. Correspondingly, the terminal device receives the second activation signaling from the network device.

[0305] The second activation signaling is used to activate Q second type of trigger states in the trigger state list. The second type of trigger state is described above and will not be repeated here. Q is an integer greater than or equal to 1 and less than or equal to 2 L -1-K, L=N, N is the length of the first field, or L is the maximum configurable value of the length of the first field specified by the communication protocol.

[0306] Optionally, the number of the second type of trigger state in the trigger state list is greater than 2 N -1-K, N is the length of the first field.

[0307] In this implementation, optionally, the second activation signaling activates at most 2 N -1-K second type of trigger states, or at most 2 N -1-K second type of trigger states are mapped to the first field. That is, at most 2 N -1-K second type of trigger states are mapped to the first field. For example, when K=1, the second activation signaling activates at most 2 N -2 second type of trigger states, that is, at most 2 N -2 second type of trigger states are mapped to the first field.

[0308] In this implementation, optionally, the second activation signaling activates at most 2 L -1-K second type of trigger states, or at most 2 L -1-K second type of trigger states are mapped to the first field. L is the maximum configurable value of the length of the first field specified by the communication protocol. For example, L=6. That is, at most 2L -1-K second type trigger states are mapped to the 2

[0309] Optionally, the second activation signaling activates 2 N -1-K second type trigger states. The 2 N -1-K values correspond to the 2 N -1-K second type trigger states. The 2 N -1-K values are values of the first field other than the K values of the first field and the value 0. For example, the 2 N -1-K values are sequentially in ascending order of values. The 2 N -1-K second type trigger states correspond. The 2 N -1-K second type trigger states are sorted in ascending or descending order of the activation order of the second type trigger states. The activation order of the second type trigger states is the sorting position of the T field for activating the second type trigger states in the second activation signaling in all T fields for activating the second type trigger states in the second activation and having a value of 1. For example, as shown in FIG. 8, the second activation signaling is the MAC CE shown in FIG. 8, the MAC CE activates 2 N -1-K second type trigger states, the 2 N -1-K second type trigger states include the second type trigger state 1, the second type trigger state 3, and the second type trigger state 4. Specifically, the T0 field, the T2 field, and the T3 field in the MAC CE correspond to values of 1 respectively, the T0 field indicates that the second type trigger state 1 is activated, the T2 field indicates that the second type trigger state 3 is activated, and the T3 field indicates that the second type trigger state 4 is activated. The T0 field is the first T field for activating the second type trigger state and having a value of 1 in the second activation signaling, the T2 field is the second T field for activating the second type trigger state and having a value of 1 in the second activation signaling, and the T3 field is the third T field for activating the second type trigger state and having a value of 1 in the second activation signaling. That is, the sorting of the Y second type trigger states is: the second type trigger state 1-the second type trigger state 3-the second type trigger state 4. The 2 N -1-K values include the vth value, the vth value is used to indicate the 2 N -1-Kth second type trigger state in the 2 N -1-K integer. For example, the second activation signaling activates 2 N -1-K second type trigger states in the trigger state list. The K values of the first field are 1 to K. The first field has a total of 2 N values, in addition to the K values and the value 0, the remaining 2N -1-K values are K+1 to 2 N -1. The remaining 2 N -1-K values correspond to the 2 N -1-K second type of trigger states. For example, the value K+1 of the first field is used to indicate 2 N -1-K first second type of trigger state of the K second type of trigger states. The value K+2 of the first field is used to indicate 2 N -1-K second second type of trigger state of the K second type of trigger states. In this way, the value 2 N -1 is used to indicate 2 N -1-K last second type of trigger state of the K second type of trigger states. For another example, the second activation signaling activates 2 N -1-K second type of trigger states. The K values of the first field described above are 2 N -K to 2 N -1. The first field has a total of 2 N values, in addition to the K values and the value 0, the remaining 2 N -1-K values are 1 to 2 N -1-K. The remaining 2 N -1-K values correspond to the 2 N -1-K second type of trigger states. For example, the value 1 of the first field is used to indicate 2 N -1-K first second type of trigger state of the K second type of trigger states. The value 2 of the first field is used to indicate 2 N -1-K second second type of trigger state of the K second type of trigger states. In this way, the value 2 N -1-K is used to indicate 2 N -1-K last second type of trigger state of the K second type of trigger states.

[0310] Optionally, in the second implementation manner, at least one or more of the following conditions is met: the number of trigger states in the trigger state list is greater than 2 N -1; or the number of second type of trigger states in the trigger state list is greater than 2 N -1-K.

[0311] Optionally, in the second implementation manner, the following condition is met: the number of trigger states in the trigger state list is less than or equal to 2 N-1. For example, the K values include 1 to K, value 1 is used to indicate the first one of the K first type trigger states, value 2 is used to indicate the second one of the K first type trigger states, and so on, and value K is used to indicate the Kth one of the K first type trigger states. Other values of the first field than the K values and value 0 can be used to indicate the second type trigger states in the trigger state list. For another example, the K values include 2 N - K to 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2

[0312] Optionally, the trigger state list is a non-periodic trigger state list.

[0313] Optionally, one or more of the first type trigger states in the trigger state list can be pre-configured, or pre-defined, or configured by the network device, without limitation. Optionally, the embodiment shown in FIG. 12 further includes step 1201a. Step 1201a can be performed before step 1201.

[0314] 1201a. The network device sends the first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0315] Step 1201a is similar to step 1101a in the embodiment shown in FIG. 11, and the related introduction of step 1101a in the embodiment shown in FIG. 11 can be referred to, which will not be repeated here.

[0316] Implementation manner three, the number of the trigger states in the trigger state list is less than 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2 N - 1; or, the number of the trigger states in the trigger state list is less than or equal to 2

[0317] Optionally, the P values of the first field correspond to the trigger states in the trigger state list. The trigger state list includes at least one first type trigger state. For example, the P values of the first field correspond to the trigger states in the trigger state list in ascending order. Optionally, the trigger states in the trigger state list are sorted in ascending or descending order according to their positions in the trigger state list. Of course, the trigger states in the trigger state list can also be sorted in other ways, which are not limited in the present application. The P values of the first field are P values other than 0. P is greater than or equal to 1 and less than or equal to 2 N -1.

[0318] Optionally, the P values include the bth value, and the bth value is used to indicate the bth trigger state in the trigger state list. P is the number of trigger states in the trigger state list. In other words, the first value in the P values is used to indicate the first trigger state in the trigger state list, the second value is used to indicate the second trigger state in the trigger state list, and so on, and the last value is used to indicate the last trigger state in the trigger state list. For example, the bth value is value b1, and value b1 is used to indicate the bth trigger state in the trigger state list. b is an integer greater than or equal to 1 and less than or equal to P, and b1 is an integer greater than or equal to 1 and less than or equal to 2 N -1. For example, the P values of the first field include 1 to P, value 1 is used to indicate the first trigger state in the trigger state list, value 2 is used to indicate the second trigger state in the trigger state list, and so on, and value P is used to indicate the Pth trigger state in the trigger state list. In this example, the bth trigger state in the trigger state list is a first type trigger state, and when the value of the first field is value b, the first field indicates the first type trigger state. For another example, the P values of the first field include 2 N -1-P to 2 N -1. Value 2 N -1-P is used to indicate the first trigger state in the trigger state list, value 2 N -1-P+1 is used to indicate the second trigger state in the trigger state list, and so on, and value 2 N -1 is used to indicate the Pth trigger state in the trigger state list. In this example, the bth trigger state in the trigger state list is a first type trigger state, and when the value of the first field is 2 N -1-P+b, the first field indicates the first type trigger state.

[0319] Optionally, the trigger state list is a non-periodic trigger state list.

[0320] The above primarily addresses the case where the trigger state list is a non-periodic trigger state list. Optionally, for the case where the trigger state list is a PUSCH-based semi-static trigger state list, the value of the first field directly indicates the trigger state in the trigger state list. In this implementation, optionally, the W possible values ​​of the first field correspond to the trigger states in the trigger state list. The trigger state list includes at least one first-class trigger state. For example, the W possible values ​​of the first field correspond to the trigger states in the trigger state list in ascending order of value. The trigger states in the trigger state list are sorted from front to back according to their position in the list. The W possible values ​​of the first field include W values ​​including 0. W can be the number of trigger states in the trigger state list. W is greater than or equal to 1 and less than or equal to 2. N An integer. Optionally, in this implementation, the scheduling signaling is a DCI scrambled by SP-CSI-RNTI.

[0321] Optionally, the W possible values ​​for the first field include the g-th value, which indicates the g-th trigger state in the trigger state list, where g is greater than 0 and less than or equal to W. For example, the g-th value is g1, which indicates the g-th trigger state in the trigger state list. g1 is greater than or equal to 0 and less than or equal to 2. N An integer of -1. For example, the W possible values ​​for the first field include 0 to W-1. A value of 0 indicates the first trigger state in the trigger state list, a value of 1 indicates the second trigger state, and so on, with the value W indicating the Wth trigger state. In this example, the g-th trigger state in the trigger state list is a first-type trigger state, and when the value of the first field is g-1, then the first field indicates this first-type trigger state.

[0322] In this implementation, the first field indicates a first-type trigger state, therefore the first uplink resource scheduled by the scheduling signaling is used to carry or transmit event-triggered measurement reports. Alternatively, the information carried by the first uplink resource scheduled by the scheduling signaling includes event-triggered measurement reports. Or, the scheduling signaling schedules the reporting of event-triggered measurement reports.

[0323] It should be noted that if the first field indicates a second type of triggering state, then the first uplink resource scheduled by the scheduling signaling is used to carry or transmit measurement reports based on non-event triggering, or the information carried by the first uplink resource scheduled by the scheduling signaling includes non-event triggering measurement reports. If the value of the first field does not correspond to a triggering state, then the first uplink resource scheduled by the scheduling signaling is used to transmit uplink data, and does not include measurement reports based on event triggering and / or measurement reports based on non-event triggering.

[0324] Implementation 2: the first field takes the first value. In other words, when the first field takes the first value, it indicates that the first uplink resource is used to carry the event-triggered measurement report.

[0325] Some possible implementations of the first value are introduced below. The present application is still applicable to other implementations, which are not limited in the present application.

[0326] Implementation 1: the first value is configured by the network device. For example, it is configured by the network device through RRC signaling. Alternatively, the first value is specified by the communication protocol, or is predefined, or is reported by the terminal device.

[0327] Optionally, the first value is 0 to 2 N one of the values in -1. Wherein, N is the length of the first field. For example, the first value is the maximum value corresponding to the first field, i.e. 2 N -1, the bits in the first field are all 1. For another example, the first value is the minimum value corresponding to the first field, i.e. 0. When the first value is 0, the bits in the first field are all 0. In this implementation, the trigger state list of the terminal device is the semi-static trigger state list based on PUSCH. Optionally, the scheduling signaling is the DCI scrambled by SP-CSI-RNTI.

[0328] Optionally, the first value is 1 to 2 N one of the values in -1. Wherein, N is the length of the first field. For example, the first value is the maximum value corresponding to the first field, i.e. 2 N -1, the bits in the first field are all 1. For another example, the first value is the minimum value corresponding to the first field except 0, i.e. 1. In this implementation, the trigger state list of the terminal device is the aperiodic trigger state list.

[0329] Optionally, if the first condition is met, and the first field takes the first value, the first uplink resource scheduled by the scheduling signaling is used to carry the event-triggered measurement report, or indicates to report the event-triggered measurement report, or indicates any one or more first-type trigger states configured or activated for the terminal device. Wherein, the first condition includes at least one of the following: the terminal device is configured with event-triggered reporting configuration; the terminal device is configured with event-triggered reporting configuration in mode A; or the terminal device sends second indication information to the network device before the scheduling signaling. The second indication information is described in detail below.

[0330] In the implementation, any second type of trigger state in the trigger state list cannot be mapped to the first value of the first field. That is, for the non-periodic trigger state list, any second type of trigger state can only be mapped to a value of the first field other than 0 and the first value. For the PUSCH-based semi-static trigger state list, any second type of trigger state can only be mapped to a value of the first field other than the first value.

[0331] In a possible implementation, the number of second type of trigger states in the trigger state list is greater than 2 N -2; or, the number of trigger states in the trigger state list is greater than 2 N -1, wherein the number of first type of trigger states in the trigger state list is 1; or, the number of trigger states in the trigger state list is greater than 2 N -2+X1, wherein the number of first type of trigger states in the trigger state list is X1, and X1 is an integer greater than 1. Optionally, before step 1001, step 1301 in the embodiment shown in FIG. 13 is further included, and step 1301 can be executed before step 1001.

[0332] 1301. The network device sends third activation signaling to the terminal device. Correspondingly, the terminal device receives the third activation signaling from the network device.

[0333] The third activation signaling is used to select or activate Y second type of trigger states in the trigger state list. For the second type of trigger state, refer to the foregoing related introduction. Y is an integer greater than or equal to 1 and less than or equal to 2 L -2, L=N, N is the length of the first field, or, L is a configurable maximum value of the length of the first field specified by the communication protocol. For example, L=6. For example, the Y second type of trigger states are the first Y second type of trigger states in the trigger state list.

[0334] The Y values of the first field correspond to the Y second type of trigger states, and the Y values of the first field include the cth value, the cth value being used to indicate the cth second type of trigger state in the Y second type of trigger states. The Y values of the first field are Y values of the first field other than 0 and the first value. c is an integer greater than or equal to 1 and less than or equal to Y. In the implementation, the third activation signaling activates at most 2 L -2 second type of trigger states. In other words, the third activation signaling maps at most 2 L -2 second type of trigger states, that is, at most 2 L -2 second type of trigger states are mapped to the first field. For example, the first value is 2 N- 1, the Y values are 1 to Y, and the value 1 is used to indicate the first of the Y second-type trigger states, the value 2 is used to indicate the second of the Y second-type trigger states, and so on, and the value Y is used to indicate the Yth of the Y second-type trigger states. For another example, the first value is 1, the Y values are 2 to Y+1, the value 2 is used to indicate the first of the Y second-type trigger states, the value 3 is used to indicate the second of the Y second-type trigger states, and so on, and the value Y+1 is used to indicate the Yth of the Y second-type trigger states. For another example, the third activation signaling activates 2 N - 2 second-type trigger states. The activated second-type trigger state corresponds to the value 2 of the first field. N - 2 values. For example, the first value is 2 N - 1, the Y values are 1 to 2 N - 2, the value 1 is used to indicate the first of the Y second-type trigger states, the value 2 is used to indicate the second of the Y second-type trigger states, and so on, and the value 2 N - 2 is used to indicate the 2nd of the Y second-type trigger states. N - 2 second-type trigger states. For another example, the first value is 1, the Y values are 2 to 2 N - 1, the value 2 is used to indicate the first of the Y second-type trigger states, the value 3 is used to indicate the second of the Y second-type trigger states, and so on, and the value 2 N - 1 is used to indicate the 2nd of the Y second-type trigger states. N - 2 second-type trigger states.

[0335] Optionally, the Y second-type trigger states are sorted in an activation order of the second-type trigger states from front to back or from back to front. The activation order of the second-type trigger states is the sorting position of a T field for activating the second-type trigger state in the third activation signaling among all T fields for activating the second-type trigger states and taking value 1 in the third activation signaling. For example, as shown in FIG. 8, the third activation signaling is a MAC CE as shown in FIG. 8. The MAC CE activates Y second-type trigger states, and the Y second-type trigger states include second-type trigger state 1, second-type trigger state 3 and second-type trigger state 4. Specifically, the T0 field, the T2 field and the T3 field in the MAC CE respectively correspond to values 1, the T0 field indicates that the second-type trigger state 1 is activated, the T2 field indicates that the second-type trigger state 3 is activated, and the T3 field indicates that the second-type trigger state 4 is activated. The T0 field is the first T field for activating the second-type trigger state and taking value 1 in the third activation signaling, the T2 field is the second T field for activating the second-type trigger state and taking value 1 in the third activation signaling, and the T3 field is the third T field for activating the second-type trigger state and taking value 1 in the third activation signaling. That is, the sorting of the Y second-type trigger states is: second-type trigger state 1-second-type trigger state 3-second-type trigger state 4.

[0336] In the implementation mode, optionally, the trigger state list is a non-periodic trigger state list.

[0337] In another possible implementation mode, the number of second-type trigger states in the trigger state list is less than or equal to 2 N -2. Or, the number of trigger states in the trigger state list is less than or equal to 2 N -1, wherein the number of first-type trigger states in the trigger state list is 1. Or, the number of trigger states in the trigger state list is less than or equal to 2 N -2+X1, wherein the number of first-type trigger states in the trigger state list is X1. Wherein the number of first-type trigger states in the trigger state list is X1, and X1 is an integer greater than 1.

[0338] In this implementation, optionally, the R values of the first field correspond to the second type of trigger states in the trigger state list. For example, the R values of the first field correspond to the second type of trigger states in the trigger state list in order from small to large or from large to small. The trigger state list is sorted in order from front to back or from back to front according to the sorting positions of the second type of trigger states in the trigger state list. The R values are values of the first field other than 0 and the first value. The R values include the dth value, and the dth value is used to indicate the dth second type of trigger state in the trigger state list. d is an integer greater than or equal to 1 and less than or equal to R. R is the number of the second type of trigger states in the trigger state list. R is greater than or equal to 1 and less than or equal to 2 N -2.

[0339] For example, the R values include the value d1, and the value d1 is used to indicate the dth second type of trigger state in the trigger state list. d1 is 1 to 2 N -1 other than the first value. For example, the first value is 2 N -1, and the R values are 1 to R. The value 1 is used to indicate the first second type of trigger state in the trigger state list, the value 2 is used to indicate the second second type of trigger state in the trigger state list, and so on, and the value R is used to indicate the Rth second type of trigger state in the trigger state list. For another example, the first value is 1, and the R values are 2 to R+1. The value 2 is used to indicate the first second type of trigger state in the trigger state list, the value 3 is used to indicate the second second type of trigger state in the trigger state list, and so on, and the value R+1 is used to indicate the Rth second type of trigger state in the trigger state list.

[0340] The above mainly aims at the case that the trigger state list is a non-periodic trigger state list. For the case that the trigger state list is a PUSCH-based semi-static trigger state list, the value of the first field directly indicates the second type of trigger state in the trigger state list. In this implementation, optionally, the Y values of the first field correspond to the second type of trigger states in the trigger state list. The trigger state list includes at least one second type of trigger state. For example, the Y values of the first field correspond to the second type of trigger states in the trigger state list in order from small to large. The second type of trigger states in the trigger state list are sorted in order from front to back according to the positions of the trigger states in the trigger state list. The Y values of the first field are Y values including 0. Y can be the number of trigger states in the trigger state list. Optionally, in this implementation, the scheduling signaling is DCI scrambled by SP-CSI-RNTI.

[0341] Optionally, the Y values ​​of the first field include the r-th value, which indicates the r-th second-type trigger state in the trigger state list. r is greater than or equal to 0 and less than or equal to Y. For example, the Y values ​​include the value r1, which indicates the r-th second-type trigger state in the trigger state list. r1 is between 0 and 2. N -1 is one of the values ​​other than the first value. For example, if the first value is 0, the Y values ​​of the first field include 1 to 2. N -1. A value of 1 indicates the first second-type trigger state in the trigger state list, a value of 2 indicates the second second-type trigger state in the trigger state list, and so on, with each value being 2. N -1 is used to indicate the second item in the trigger status list. N -1 second-type triggered state. For example, the first value is 2. N -1, the first field's Y values ​​range from 0 to 2. N -2. A value of 0 indicates the first Class II trigger state in the trigger state list, a value of 1 indicates the second Class II trigger state, and so on, up to a value of 2. N -2 is used to indicate the second item in the trigger status list. N -1 second-type triggered state.

[0342] In one possible implementation, the network device does not configure a first type of trigger state for the terminal device. If the first field is a first value, it indicates that the first uplink resource is used to carry event-triggered measurement reports. In another possible implementation, the network device configures one or more first type of trigger states for the terminal device. Optionally, the network device activates some or all of the one or more first type of trigger states for the terminal device. When the first field is a first value, it indicates that the first uplink resource is used to carry event-triggered measurement reports. In this implementation, the first field indicates one or more first type of trigger states.

[0343] Optionally, one or more of the first type of trigger states in the trigger state list can be pre-configured, pre-defined, or configured by the network device; this application does not limit the specifics. Optionally, the embodiment shown in Figure 13 further includes step 1301a. Step 1301a can be performed before step 1301.

[0344] 1301a. The network device sends first configuration information to the terminal device. Correspondingly, the terminal device receives the first configuration information from the network device.

[0345] Step 1301a is similar to step 1101a in the foregoing embodiment shown in FIG. 11, and details can be referred to the related description of step 1101a in the foregoing embodiment shown in FIG. 11, which will not be repeated here.

[0346] In a second implementation, the first value is X+1, where X is the number of second-type trigger states configured or activated by the network device for the terminal device. That is, when the value of the first field is X+1, it indicates that the first uplink resource is used to carry the event-triggered measurement report.

[0347] Optionally, the X values of the first field correspond to X second-type trigger states configured or activated by the network device for the terminal device. For example, the X values of the first field correspond to the X second-type trigger states in ascending or descending order of value. The X second-type trigger states are sorted in ascending or descending order of position in the trigger state list, or in ascending or descending order of activation order of the second-type trigger states. The activation order of the second-type trigger states can be referred to the foregoing related example description. The X values include an e-th value, where the e-th value is used to indicate an e-th second-type trigger state in the X second-type trigger states, and e is an integer greater than or equal to 1 and less than or equal to X. For example, the X values include a value e1, and the value e1 is used to indicate an e-th second-type trigger state in the X second-type trigger states. e1 is 0 to 2 N X. For example, the X values include 1 to X, the value 1 is used to indicate a first second-type trigger state in the X second-type trigger states, the value 2 is used to indicate a second second-type trigger state in the X second-type trigger states, and so on, and the value X is used to indicate an X-th second-type trigger state in the X second-type trigger states. The value 0 or any value from X+2 to 2 N -1 in the foregoing embodiment is used to indicate the non-event-triggered measurement report. The value X+1 of the first field is used to indicate the event-triggered measurement report, or to indicate that the first uplink resource is used to carry the event-triggered measurement report, or to indicate any one or more first-type trigger states configured or activated for the terminal device.

[0348] In this implementation, for the aperiodic trigger state list, the value range of X is 1 to 2 N -2. In one possible implementation, when the number of second-type trigger states configured by the network device for the terminal device is less than or equal to 2 N -2, X is the number of second-type trigger states configured by the network device for the terminal device. In another possible implementation, when the number of second-type trigger states configured by the network device for the terminal device is greater than 2N -2, X is the number of the second type of trigger states activated by the network device for the terminal device.

[0349] Optionally, the X+1 values of the first field correspond to X+1 second type of trigger states configured or activated by the network device for the terminal device. For example, the X+1 values of the first field correspond to X+1 second type of trigger states in ascending order of values, and the X+1 second type of trigger states are sorted in ascending order of positions in the trigger state list or in ascending order of activation sequence of the second type of trigger states. The X+1 values include the s-th value, and the s-th value is used to indicate the s-th second type of trigger state in the X+1 values. s is greater than or equal to 1 and less than or equal to X+1. For example, the X+1 values include 0 to X, the value 0 is used to indicate the first second type of trigger state in the X+1 second type of trigger states, the value 1 is used to indicate the second second type of trigger state in the X+1 second type of trigger states, and so on, and the value X+1 is used to indicate the X+1-th second type of trigger state in the X+1 second type of trigger states. And the value of the first field is any value from X+2 to 2 N -1, which is used for reporting no event triggered or non-event triggered measurement report. The value X+1 of the first field is used to indicate reporting event triggered measurement report.

[0350] In this implementation, optionally, for the PUSCH-based trigger state list, the value range of X is 0-2 N -2. In one possible implementation, when the number of the second type of trigger states configured by the network device for the terminal device is less than or equal to 2 N -2, X is the number of the second type of trigger states configured by the network device for the terminal device. In another possible implementation, when the number of the second type of trigger states configured by the network device for the terminal device is greater than 2 N -2, X=2 N -2.

[0351] In one possible implementation, the network device does not configure the terminal device with the first type of trigger state. If the value of the first field is the first value, it indicates that the first uplink resource is used to carry the event triggered measurement report. In another possible implementation, the network device configures the terminal device with one or more first type of trigger states. Optionally, the network device activates part or all of the one or more first type of trigger states for the terminal device. When the value of the first field is the first value, it indicates that the first uplink resource is used to carry the event triggered measurement report. In this implementation, the first field indicates one or more first type of trigger states.

[0352] Optionally, one or more first-type trigger states in the trigger state list can be pre-configured, or pre-defined, or configured by the network device, without any limitation in the present application. The configuration procedure of the first-type trigger state can refer to the related description of step 1301a in the embodiment shown in FIG. 13, without any limitation in the present application.

[0353] Optionally, the scheduling signaling further includes a second field, and the second field is used to indicate that the first uplink resource is further used to transmit uplink data.

[0354] The step 1001 can be understood as the step a in the mode A.

[0355] Optionally, the embodiment shown in FIG. 10 further includes a step 1001a. The step 1001a can be performed before the step 1001.

[0356] 1001a. The terminal device sends second indication information to the network device. Correspondingly, the network device receives the second indication information from the terminal device.

[0357] The second indication information is used to indicate that there is an event occurrence. Alternatively, the second indication information is used to indicate to the network device that the measurement report triggered by the event needs to be reported. Alternatively, the second indication information is used to indicate that there is at least one event occurrence.

[0358] Optionally, the second indication information is carried in the second uplink resource. The step 1001a can be understood as the step a in the mode A.

[0359] Optionally, the second indication information is carried in one or more second uplink resources.

[0360] The second indication information is used to request the network device to schedule the first uplink resource for the terminal device. Alternatively, the second indication information is used to indicate that one or more event trigger report configurations are associated with event occurrences.

[0361] The one or more second uplink resources are second uplink resources associated with at least one first-type trigger state in the first-type trigger states activated by the first activation signaling. The second uplink resource associated with the trigger state can be understood as the second uplink resource associated with the event trigger report configuration associated with the trigger state. For example, the one or more second uplink resources are the second uplink resources associated with the one or more event trigger report configurations. The one or more event trigger report configurations are the event trigger report configurations associated with at least one first-type trigger state in the first-type trigger states activated by the first activation signaling.

[0362] In a possible implementation, different first-type trigger states are associated with different second uplink resources. This implementation further distinguishes the following two cases.

[0363] Case one: one first type trigger state is associated with one or more event triggered report configurations, when the one or more event triggered report configurations include multiple event triggered report configurations, the multiple event triggered report configurations are associated with the same second uplink resource. Different first type trigger states are associated with different second uplink resources. For example, the first type trigger state #1 is associated with the event triggered report configuration #1 and the event triggered report configuration #2, the event triggered report configuration #1 and the event triggered report configuration #2 are both associated with the second uplink resource 1. That is, the first type trigger state #1 is associated with the second uplink resource 1. The first type trigger state #2 is associated with the event triggered report configuration #3 and the event triggered report configuration #4, the event triggered report configuration #3 and the event triggered report configuration #4 are both associated with the second uplink resource 2. That is, the first type trigger state #2 is associated with the second uplink resource 2. Therefore, it can be known that the second uplink resource associated with the first type trigger state #1 is different from the second uplink resource associated with the first type trigger state #2.

[0364] Case two: one first type trigger state is associated with one or more event triggered report configurations. When the one or more event triggered report configurations include multiple event triggered report configurations, different event triggered report configurations are associated with different second uplink resources. Different first type trigger states are associated with different second uplink resources. For example, the first type trigger state #1 is associated with the event triggered report configuration #1 and the event triggered report configuration #2, the event triggered report configuration #1 is associated with the second uplink resource 1, and the event triggered report configuration #2 is associated with the second uplink resource 2. That is, the first type trigger state #1 is associated with the second uplink resource 1 and the second uplink resource 2. The first type trigger state #2 is associated with the event triggered report configuration #3 and the event triggered report configuration #4, the event triggered report configuration #3 is associated with the second uplink resource 3, and the event triggered report configuration #4 is associated with the second uplink resource 4. That is, the first type trigger state #2 is associated with the second uplink resource 3 and the second uplink resource 4. Therefore, it can be known that the second uplink resource associated with the first type trigger state #1 is different from the second uplink resource associated with the first type trigger state #2.

[0365] Case three: one first type trigger state is associated with one or more event triggered reporting configurations. When the one or more event triggered reporting configurations include multiple event triggered reporting configurations, the multiple event triggered reporting configurations are associated with at least two second uplink resources. Different first type trigger states are associated with different second uplink resources. For example, the first type trigger state #1 is associated with the event triggered reporting configuration #1, the event triggered reporting configuration #2 and the event triggered reporting configuration #3. The event triggered reporting configuration #1 is associated with the second uplink resource 1. The event triggered reporting configuration #2 and the event triggered reporting configuration #3 are both associated with the second uplink resource 2. That is, the first type trigger state #1 is associated with the second uplink resource 1 and the second uplink resource 2. The first type trigger state #2 is associated with the event triggered reporting configuration #4 and the event triggered reporting configuration #5. The event triggered reporting configuration #4 is associated with the second uplink resource 3, and the event triggered reporting configuration #5 is associated with the second uplink resource 4. That is, the first type trigger state #2 is associated with the second uplink resource 3 and the second uplink resource 4. Therefore, it can be known that the second uplink resource associated with the first type trigger state #1 is different from the second uplink resource associated with the first type trigger state #2.

[0366] In another possible implementation, different first type trigger states are associated with the same second uplink resource.

[0367] For example, the first type trigger state #1 is associated with the event triggered reporting configuration #1 and the event triggered reporting configuration #2, and the event triggered reporting configuration #1 and the event triggered reporting configuration #2 are both associated with the second uplink resource 1. That is, the first type trigger state #1 is associated with the second uplink resource 1. The first type trigger state #2 is associated with the event triggered reporting configuration #3 and the event triggered reporting configuration #4, and the event triggered reporting configuration #3 and the event triggered reporting configuration #4 are both associated with the second uplink resource 1. Therefore, it can be known that the second uplink resource associated with the first type trigger state #1 is the same as the second uplink resource associated with the first type trigger state #2.

[0368] When at least one first type trigger state associated with the second uplink resource is activated, and a corresponding condition is met, the terminal device sends the second uplink resource associated with the at least one first type trigger state. The condition includes that at least one event triggered reporting configuration associated with the at least one first type trigger state corresponds to an event.

[0369] In this embodiment, each event triggered reporting configuration is associated with a first reporting resource and a second reporting resource. The first reporting resource is used to report a measurement result corresponding to the event triggered reporting configuration. The second reporting resource is used to request the network device to schedule the first uplink resource for the terminal device. The measurement result corresponding to the event triggered reporting configuration is a measurement result of a reference signal corresponding to a reference signal resource associated with the event triggered reporting configuration.

[0370] Optionally, the different event-triggered reporting configurations can be associated with the same first reporting resource or different first reporting resources. The different event-triggered reporting configurations can be associated with the same second reporting resource or different second reporting resources.

[0371] Optionally, the one or more event-triggered reporting configurations include one or more event-triggered reporting configurations associated with the same second uplink resource. Then, the second indication information is carried on the same second uplink resource.

[0372] Optionally, the one or more event-triggered reporting configurations include a plurality of event-triggered reporting configurations associated with different second uplink resources. Then, the second indication information is carried on the plurality of second uplink resources.

[0373] In a possible case, a first type of trigger state is associated with one or more event-triggered reporting configurations, and when the one or more event-triggered reporting configurations include a plurality of event-triggered reporting configurations, the plurality of event-triggered reporting configurations are associated with at least two second uplink resources. If the terminal sends one of the at least two second uplink resources, the terminal device cannot send the remaining second uplink resources of the at least two second uplink resources. In other words, the terminal device can only send one of the at least two second uplink resources. Alternatively, if the terminal device sends one of the at least two second uplink resources, the terminal device does not send the remaining second uplink resources of the at least two second uplink resources before receiving the scheduling signaling. In other words, before receiving the scheduling signaling, the terminal can only send one of the at least two second uplink resources.

[0374] Optionally, the embodiment shown in FIG. 10 further includes step 1000a. Step 1000a can be performed before step 1001.

[0375] 1000a. The terminal device sends capability information to the network device. Correspondingly, the network device receives the capability information from the terminal device.

[0376] The capability information is used to indicate at least one of the following: information about whether the terminal device supports event-triggered reporting, the maximum number of trigger states associated with the event-triggered reporting configurations supported by the terminal device, or the maximum number of event-triggered reporting configurations associated with one trigger state supported by the terminal device.

[0377] It should be noted that if the terminal device reports the capability information, it indicates that the terminal device supports the capability indicated by the capability information; if the terminal device does not report the capability information, it indicates that the terminal device does not support the capability indicated by the capability information. Alternatively, the terminal device can report part of the capability information, and when the terminal device supports the capability indicated by the part of the capability information, it implicitly indicates that the terminal device supports the capability indicated by another part of the capability information, but the terminal device can not report the other part of the capability information. For example, the terminal device indicates to the network device that the terminal device supports the capability of event-triggered reporting, and the communication protocol stipulates the maximum number of trigger states of the associated event-triggered reporting configuration supported by the terminal device, which is not limited in the present application.

[0378] Optionally, if the embodiment shown in FIG. 10 further includes step 1001a, step 1000a can be performed before step 1001a.

[0379] Optionally, the embodiment shown in FIG. 10 further includes step 1000b. Step 1000b can be performed before step 1001.

[0380] 1000b, the network device sends second configuration information to the terminal device. Correspondingly, the terminal device receives the second configuration information from the network device.

[0381] The second configuration information is used to configure at least one of the following events: the first event, the second event, or the third event. The first event, the second event, and the third event are introduced below respectively.

[0382] The first event includes that the signal quality of the serving beam of the terminal device is lower than the first threshold value. Alternatively, the signal quality of the serving beam of the terminal device is less than the first threshold value. Alternatively, the signal quality of the serving beam of the terminal device is less than or equal to the first threshold value.

[0383] The second event includes that there is at least one new beam whose signal quality is higher than the signal quality of the serving beam of the terminal device by the second threshold value. Alternatively, there is at least one new beam whose signal quality is higher than the signal quality of the serving beam of the terminal device, and the difference between the signal quality of the at least one new beam and the signal quality of the serving beam of the terminal device is greater than the second threshold value. Alternatively, there is at least one new beam whose signal quality is higher than the signal quality of the serving beam of the terminal device, and the difference between the signal quality of the at least one new beam and the signal quality of the serving beam of the terminal device is greater than or equal to the second threshold value.

[0384] The third event includes: the signal quality of at least one new beam is higher than the signal quality of the first active beam and is higher than a third threshold value. Alternatively, the signal quality of at least one new beam is higher than the signal quality of the first active beam, and a difference between the signal quality of at least one new beam and the signal quality of the first active beam is greater than the third threshold value. Alternatively, the signal quality of at least one new beam is higher than the signal quality of the first active beam, and a difference between the signal quality of at least one new beam and the signal quality of the first active beam is greater than or equal to the third threshold value.

[0385] The service beam of the terminal device is a beam currently used by the terminal device and the network device for transmission. It should be noted that if the terminal device transmits with multiple TRPs, the terminal device includes multiple service beams, and the multiple service beams correspond to the multiple TRPs one by one.

[0386] In a possible implementation, the one or more new beams of the terminal device are beams of the terminal device other than the service beam, or in other words, the one or more new beams are beams of the terminal device distinguished from the service beam. For example, the one or more new beams can be understood as candidate beams of the terminal device. For example, the one or more new beams are beams corresponding to TCI states other than the TCI state indicated for the terminal device in the TCI states configured by the network device for the terminal device. For another example, the one or more new beams are beams corresponding to TCI states other than the TCI state indicated for the terminal device in the TCI states activated by the network device for the terminal device. The service beam and the one or more new beams are configured by the network device for the terminal device for a same measurement reporting process or a same measurement reporting configuration. Therefore, the one or more new beams are referred to as one or more new beams corresponding to the service beam. The resource type corresponding to the service beam is the same as the resource type corresponding to the one or more new beams. For example, the resource corresponding to the service beam is an SSB resource, and the resource corresponding to the one or more new beams is an SSB resource. For another example, the resource corresponding to the service beam is a CSI-RS resource, and the resource corresponding to the one or more new beams is a CSI-RS resource.

[0387] In another possible implementation, the one or more new beams of the terminal device are beams of the terminal device other than the first active beam. Alternatively, the one or more new beams of the terminal device are beams of the terminal device distinguished from the first active beam. For example, the one or more new beams can be beams other than the first active beam activated by the network device for the terminal device. Optionally, the first active beam can or can not be the service beam of the terminal device. When the network device indicates the first active beam as the service beam of the terminal device, the first active beam is the service beam.

[0388] In another possible implementation, the one or more new beams of the terminal device are beams other than the beams activated by the network device for the terminal device. For example, the one or more new beams are beams corresponding to TCI states other than the TCI states activated by the network device for the terminal device in the TCI states configured by the network device for the terminal device. For another example, the one or more new beams are beams corresponding to one or more reference signals for monitoring new beams, excluding the beam corresponding to the activated TCI state.

[0389] Optionally, the serving beam includes at least one of the following:

[0390] 1. a beam corresponding to a QCL Type D reference signal in a TCI state (i.e., a common TCI state) indicated by the network device for the terminal device;

[0391] 2. a beam corresponding to a reference signal associated with a QCL Type D reference signal in a TCI state (i.e., a common TCI state) indicated by the network device for the terminal device;

[0392] In the above first and second items, in the common mode, if the terminal device performs transmission with a single TRP, the network device indicates one TCI state for the terminal device. If the terminal device performs transmission with multiple TRPs, the network device indicates multiple TCI states for the terminal device, i.e., the indicated TCI states are multiple common TCI states.

[0393] 3. a beam corresponding to a QCL Type D reference signal in a downlink TCI state indicated by the network device for the terminal device;

[0394] 4. a beam corresponding to a reference signal in an uplink TCI state indicated by the network device for the terminal device;

[0399] In the seventh and eighth items above, in the separate mode, if the terminal device transmits with a single TRP, the network device indicates one downlink TCI state and one uplink TCI state for the terminal device. If the terminal device transmits with multiple TRPs, the network device indicates multiple downlink TCI states and multiple uplink TCI states for the terminal device, one downlink TCI state and one uplink TCI state corresponding to each TRP.

[0400] 9. The beam corresponding to the one or more reference signals for monitoring the serving beam configured or indicated by the network device for the terminal device.

[0409] 2. The beam corresponding to the QCL Type D reference signal in the TCI state configured by the network device for the terminal device other than the TCI state indicated by the network device for the terminal device (i.e., the common TCI state);

[0410] 3. The beam corresponding to the reference signal associated with the QCL Type D reference signal in the TCI state activated by the network device for the terminal device other than the TCI state indicated by the network device for the terminal device (i.e., the common TCI state);

[0411] 4. The network device configures the terminal device with a beam corresponding to a QCL Type D reference signal in a TCI state other than a TCI state indicated by the network device to the terminal device (i.e., a common TCI state);

[0415] 8. The network device configures or activates a beam corresponding to a reference signal associated with a reference signal in an uplink TCI state other than an uplink TCI state indicated by the network device to the terminal device.

[0416] 9. The network device configures or activates a beam corresponding to a QCL Type D reference signal in a downlink TCI state other than a downlink TCI state indicated by the network device to the terminal device, and a beam corresponding to a reference signal in an uplink TCI state other than an uplink TCI state indicated by the network device to the terminal device;

[0417] 10. The network device configures or activates a beam corresponding to a reference signal associated with a QCL Type D reference signal in a downlink TCI state other than a downlink TCI state indicated by the network device to the terminal device, and a beam corresponding to a reference signal associated with a reference signal in an uplink TCI state other than an uplink TCI state indicated by the network device to the terminal device; or,

[0418] 11. The network device configures the terminal device with a beam corresponding to one or more reference signals for monitoring a new beam.

[0419] The serving beam and the one or more new beams are configured by the network device to the terminal device for a same measurement reporting procedure or a same measurement reporting configuration. Therefore, the one or more new beams are referred to as one or more new beams corresponding to the serving beam. The terminal device measures the serving beam and the one or more new beams.

[0420] The first threshold value, the second threshold value, and the third 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 present application does not limit the details.

[0421] The second configuration information can further configure more events, and the present application does not limit the details.

[0422] 1002. The terminal device sends the first measurement report triggered by the event to the network device through the first uplink resource. Correspondingly, the network device receives the first measurement report triggered by the event from the terminal device through the first uplink resource.

[0423] In a possible implementation, the network device configures a first event for the terminal device. When the first event occurs, the first measurement report triggered by the event includes information of a serving beam. For example, the first measurement report triggered by the event includes at least one of the following: information of the first event, an index of the first event, a signal quality of the serving beam, or an index of the serving beam.

[0424] In another possible implementation, the network device configures a second event for the terminal device.

[0426] Optionally, the scheduling signaling further includes a second field, and the second field is used to indicate that the first uplink resource is also used to transmit uplink data. The terminal device sends the uplink data to the network device through the first uplink resource. Correspondingly, the network device receives the uplink data from the terminal device through the first uplink resource.

[0427] In the embodiments of the present application, the terminal device receives scheduling signaling from the network device. The scheduling signaling is used for scheduling a first uplink resource, and the scheduling signaling includes first indication information, which is used for determining that the first uplink resource is used for carrying an event-triggered measurement report. Then, the terminal device sends the event-triggered first measurement report to the network device through the first uplink resource. The network device schedules the uplink resource for the terminal device to report the event-triggered measurement report, and the terminal device sends the event-triggered first measurement report to the network device through the first uplink resource. The unnecessary measurement report is avoided, and the reporting overhead is reduced.

[0428] The step 1001a, the step 1001 and the step 1102 in the embodiment shown in FIG. 10 are introduced from the positive angle of the scheme executed by the terminal device. The scheme of the present application is introduced from the negative angle as follows. Specifically, the present application further provides another embodiment, and the scheme of the embodiment includes: if the first type of trigger state is not activated, the terminal device does not send the first indication information through one or more second uplink resources, or the terminal device does not monitor one or more events, or the terminal device does not measure one or more reference signal resources.

[0429] The one or more second uplink resources are second uplink resources associated with the first type of trigger state. The second uplink resources associated with the first type of trigger state refer to second uplink resources associated with the event-triggered report configuration of the first type of trigger state. The one or more event-triggered report configurations are event-triggered report configurations associated with the first type of trigger state. The first indication information is used for requesting the network device to schedule the first uplink resource for the terminal device. The first uplink resource is used for carrying the event-triggered measurement report. The one or more events are events associated with the one or more event-triggered report configurations. The one or more reference signal resources are reference signal resources associated with the one or more event-triggered report configurations.

[0430] Optionally, the first type of trigger state is associated with one or more event-triggered report configurations, and the one or more event-triggered report configurations are associated with the same second uplink resource. When the first type of trigger state is not activated, the terminal device does not send the second uplink resource.

[0431] Optionally, the first type of trigger state is associated with a plurality of event-triggered report configurations, and different event-triggered report configurations in the plurality of event-triggered report configurations are associated with different second uplink resources. When the first type of trigger state is not activated, the terminal device sends the second uplink resources associated with the plurality of event-triggered report configurations.

[0432] Optionally, the embodiment further includes the following step: the terminal device receives one or more trigger states configured by the network device. The one or more trigger states are the first type of trigger states. Each trigger state in the one or more trigger states is associated with one or more event-triggered reporting configurations.

[0433] In a possible implementation, different trigger states in the one or more trigger states are associated with different second uplink resources. The implementation further distinguishes the following two cases.

[0434] Case one: one trigger state in the one or more trigger states is associated with one or more event-triggered reporting configurations, and the one or more event-triggered reporting configurations are associated with the same second uplink resource. For related examples of the case one, please refer to the related description in the foregoing.

[0435] Case two: different trigger states in the one or more trigger states are associated with different second uplink resources. For related examples of the case two, please refer to the related description in the foregoing.

[0436] In another possible implementation, different trigger states in the one or more trigger states are associated with the same second uplink resource. If none of the first type of trigger states associated with a certain second uplink resource is activated, the terminal device cannot send the second uplink resource.

[0437] In the embodiment, for the first type of trigger state that is not activated by the network device, the terminal device does not report a scheduling indication for requesting the network device to schedule the first uplink resource, or in other words, the terminal device does not perform measurement on a corresponding reference signal resource, or in other words, the terminal device does not perform corresponding event monitoring. In this way, measurement resources and reporting resources are avoided from being wasted.
