Description

Communication method and related apparatus

[0001] This application claims priority from the Chinese patent application No. 202411401355.1 filed on September 30, 2024, and entitled "Communication method and related apparatus", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

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

[0003] Multiple input multiple output (MIMO) is an antenna system that uses multiple antennas at the transmitting end and the receiving end to form multiple channels in order to improve channel capacity. When a base station transmits data to a user equipment (UE) using MIMO technology, it needs to rely on the reference signal measurement results fed back by the UE. Therefore, the reference signal measurement between the base station and the UE is crucial to the transmission performance of the MIMO system.

[0004] Currently, the base station needs to first send signaling for the configuration of reference signal measurement to inform the UE of the time and behavior of reference signal measurement; then the base station sends reference signals to the UE for reference signal measurement; the UE measures according to the reference signals sent by the base station to obtain reference signal measurement results; and the base station determines the precoding information for the downlink of service data according to the reference signal measurement results reported by the UE, and then transmits the service data.

[0005] However, the beam measurement result accuracy based on the reference signal measurement result is low, which misleads the network side to perform incorrect operations based on the beam measurement result. SUMMARY

[0006] Embodiments of the present application provide a communication method and related apparatus, which can improve the accuracy of the reported beam measurement result to effectively assist the network side to perform correct operations.

[0007] In a first aspect, embodiments of the present application provide a communication method applied to a first communication apparatus. It can be understood that the communication method can be executed by the first communication apparatus, which can be a terminal device, a chip (system) or circuit for the terminal device, and the present application does not limit this. The communication method comprises:

[0008] receiving K first reference signals and L second reference signals from a second communication apparatus, K is an integer greater than 0, and L is an integer greater than 0;

[0012] based on the measurement result corresponding to each of the K first reference signals and / or the number of first events corresponding to each of the K*L pairs of reference signals, determine triggering of reporting of a beam measurement.

[0013] In an embodiment of the present application, a communication method is provided, a second communication device sends K first reference signals and L second reference signals to a first communication device, and correspondingly, the first communication device receives the K first reference signals and the L second reference signals from the second communication device. The first communication device measures the K first reference signals to obtain first measurement results, and measures the L second reference signals to obtain second measurement results. The first communication device obtains a measurement result corresponding to each of the K first reference signals based on the first measurement results, and obtains a number of first events corresponding to each of the K*L pairs of reference signals based on the first measurement results and the second measurement results. The first communication device determines triggering of reporting of a beam measurement based on the measurement result corresponding to each of the K first reference signals and / or the number of first events corresponding to each of the K*L pairs of reference signals. The communication device herein can also be a processor / chip that can execute computer instructions, and the embodiments of the present application do not limit this.

[0014] The K first reference signals and the L second reference signals in the embodiments of the present application can be transmitted / received once or multiple times, and the embodiments of the present application do not limit this. Correspondingly, the K first reference signals and the L second reference signals in the embodiments of the present application can also be measured once or multiple times, and the first measurement results and the second measurement results obtained can include one or more measurement results, and the embodiments of the present application do not limit this.

[0015] The measurement result corresponding to each of the K first reference signals obtained based on the first measurement result in the embodiments of the present application can include one measurement result corresponding to one measurement of each first reference signal, can include a plurality of measurement results corresponding to a plurality of measurements of each first reference signal, and can also include one measurement result calculated according to the plurality of measurement results, and the embodiments of the present application do not limit this.

[0016] The first event in the embodiments of the present application includes that the difference between one measurement result corresponding to one of the L second reference signals and one measurement result corresponding to one of the K first reference signals is greater than a first threshold. Optionally, the first threshold can be specified by a protocol, or can be configured by the second communication device, or can be autonomously determined by the first communication device, and the embodiments of the present application do not limit this. It can be understood that the first threshold can be adjusted according to the communication requirements of different application scenarios, and the embodiments of the present application do not limit this. Optionally, the first event can also be referred to as "event 7 (Event-7)", and the embodiments of the present application do not limit the specific name of the first event.

[0017] Currently, as long as one measurement result of a reference signal corresponding to an inactivated beam is higher than one measurement result of a reference signal corresponding to an activated beam and is higher than a threshold, beam measurement reporting is triggered. However, the measurement result corresponding to the reference signal fluctuates greatly with time, and one measurement result at a certain moment cannot completely reflect the quality of the reference signal. Therefore, according to the current triggering mechanism of beam measurement reporting, the accuracy of the triggered beam measurement result is low, thereby misleading the network side to perform incorrect operations based on the beam measurement result.

[0018] In the embodiments of the present application, the number of times of the first event corresponding to each of the K first reference signals and / or each pair of the KxL reference signals is determined to trigger beam measurement reporting, which can reduce or even eliminate the inaccuracy caused by the fluctuation of the measurement result corresponding to the reference signal with time, thereby improving the accuracy of the reported beam measurement result to effectively assist the network side to perform correct operations.

[0019] In a possible implementation, the K first reference signals include at least one reference signal corresponding to a first beam, and the first beam is a beam not used for current data transmission between the first communication device and the second communication device; and the L second reference signals include at least one reference signal corresponding to a second beam, and the second beam is an inactivated beam.

[0020] In the embodiment, the K first reference signals include at least one reference signal corresponding to a first beam, the first beam being a beam not used in current data transmission between the first communication device and the second communication device but activated, and the first beam can be referred to as an "active beam" optionally, and the specific name of the first beam is not limited in the embodiment. The L second reference signals include at least one reference signal corresponding to a second beam, the second beam being an inactivated beam, and the second beam can be referred to as a "new beam" optionally, and the specific name of the second beam is not limited in the embodiment. It can be understood that, by using the beam measurement reporting triggering mechanism in the embodiment, when it is determined to trigger the beam measurement reporting, the one or more beams not used in current data transmission between the first communication device and the second communication device but activated (i.e., the first beam) can be replaced by one or more inactivated beams with better quality (i.e., the second beam) based on the reported measurement results, so as to improve the data transmission efficiency between the first communication device and the second communication device.

[0023] The obtaining the measurement result corresponding to each first reference signal in the K first reference signals comprises:

[0024] obtaining the measurement result corresponding to each first reference signal in the K first reference signals in a second time window;

[0025] The first time window and the second time window are the same or overlap.

[0026] In the embodiment, the number of the first events corresponding to each of the K*L pairs of reference signals is within a first time window, the measurement results corresponding to each of the K first reference signals are within a second time window, and the first time window and the second time window can be the same or overlap. Optionally, the first time window and the second time window can be completely the same, or the first time window can contain the second time window, or the second time window can contain the first time window, or the first time window and the second time window can partially overlap, and the first time window is after the second time window, or the first time window and the second time window can partially overlap, and the first time window is before the second time window, and the like, which are not limited in the embodiments of the present application. Optionally, the second time window can also be a time window for measuring the L second reference signals, which is not limited in the embodiments of the present application. Through the configuration of the first time window and / or the second time window in the embodiments of the present application, the inaccuracy caused by the fluctuation of the measurement results corresponding to the reference signals over time can be reduced or even eliminated, so that the accuracy of the reported beam measurement results can be improved to effectively assist the network side to perform correct operations.

[0027] Optionally, one time window can be configured for the measurement of all K first reference signals, or multiple time windows can be configured for the measurement of different first reference signals or a set of first reference signals in the K first reference signals, which is not limited in the embodiments of the present application.

[0028] Optionally, one time window can be configured for the measurement of all L second reference signals, or multiple time windows can be configured for the measurement of different second reference signals or a set of second reference signals in the L second reference signals, which is not limited in the embodiments of the present application.

[0029] In a possible implementation, the first time window and / or the second time window is specified by a protocol, or is configured by the second communication device, or is configured by the first communication device.

[0030] In the embodiment, the first time window and / or the second time window can be specified by a protocol, or can be configured by the second communication device, or can be determined by the first communication device, which is not limited in the embodiments of the present application.

[0031] In a possible implementation, the measurement result corresponding to each of the K first reference signals is determined by one or more reference signal received power (RSRP) corresponding to each first reference signal.

[0032] In the embodiment, the measurement result corresponding to each of the K first reference signals includes one or more measurement results corresponding to each of the K first reference signals, and specifically can include one or more reference signal received powers (RSRP) corresponding to each of the K first reference signals and determined by the one or more RSRP corresponding to each of the K first reference signals. Alternatively, the measurement result corresponding to each of the K first reference signals can be obtained by averaging or weighted averaging or other calculation of the one or more RSRP corresponding to each of the K first reference signals, and the embodiments of the present application do not limit this. Alternatively, the RSRP can be replaced by a signal to interference plus noise ratio (SINR), a reference signal receiving quality (RSRQ), a received signal strength indication (RSSI) or other measurement results, and the embodiments of the present application do not limit this. Through the embodiments of the present application, the inaccuracy caused by the fluctuation of the measurement result corresponding to the reference signal over time can be reduced or even eliminated, so that the accuracy of the reported beam measurement result can be improved to effectively assist the network side to perform correct operation.

[0033] In a possible implementation, the determining of the triggering of the beam measurement reporting based on the measurement result corresponding to each of the K first reference signals and / or the number of the first event corresponding to each of the K*L pairs of reference signals includes:

[0034] The K first reference signals are sorted in descending order of the measurement result corresponding to each of the K first reference signals.

[0035] If the number of the first event corresponding to the first pair of reference signals in the K*L pairs of reference signals is greater than or equal to a second threshold, the beam measurement reporting is triggered; wherein the first pair of reference signals includes a reference signal A and a reference signal B, the reference signal A is a first reference signal ranked in an Mth position in the K first reference signals, and M is an integer satisfying 0

[0036] In the embodiment, a possible implementation of determining to trigger beam measurement reporting is provided, specifically, K first reference signals are sorted in descending order according to measurement results corresponding to each first reference signal, and if the number of times of a first event corresponding to a first pair of reference signals in K*L pairs of reference signals is greater than or equal to a second threshold, it is determined to trigger beam measurement reporting. The first pair of reference signals includes reference signal A and reference signal B, and the reference signal A is a first reference signal ranked in the Mth position in the K first reference signals, and the reference signal B is a second reference signal in the L second reference signals. It can be understood that for the first reference signal ranked in the Mth position in the K first reference signals (assuming it is reference signal A), if the number of times of a first event between one second reference signal (assuming it is reference signal B) and the first reference signal is greater than or equal to the second threshold, it is determined to trigger beam measurement reporting. Compared with the current method of triggering beam measurement reporting as long as the measurement result of the reference signal corresponding to the unactivated beam pair is higher than the measurement result of the reference signal corresponding to the activated beam, and the measurement result is higher than a threshold, the embodiment of the application determines to trigger beam measurement reporting based on the measurement result corresponding to each first reference signal in the K first reference signals and the number of times of the first event corresponding to each pair of reference signals in the K*L pairs of reference signals, which can reduce or even eliminate the inaccuracy caused by the fluctuation of the measurement result corresponding to the reference signal over time, thereby improving the accuracy of the reported beam measurement result, to effectively assist the network side to perform correct operation.

[0037] In a possible implementation, the second threshold is specified by a protocol, or is configured by the second communication device, or is configured by the first communication device.

[0038] In the embodiment, the second threshold described above can be specified by a protocol, or can be configured by the second communication device, or can be autonomously determined by the first communication device, and the embodiment of the application does not limit this. It can be understood that the second threshold can be adjusted according to the communication requirements of different application scenarios, and the embodiment of the application does not limit this.

[0042] In the embodiment, a possible specific implementation of determining to trigger beam measurement reporting is provided, specifically, based on the number of times of the first event corresponding to each pair of reference signals in the KxL pairs of reference signals, the maximum number of L times of the first event corresponding to each first reference signal in the K first reference signals is obtained, and if there is a first reference signal set in the K first reference signals, it is determined to trigger beam measurement reporting. Wherein the maximum number of L times of the first event corresponding to each first reference signal in the first reference signal set is greater than or equal to a third threshold, and the number of first reference signals in the first reference signal set is greater than or equal to a fourth threshold. It can be understood that for the first reference signal whose signal quality is in the Nth place (N is an integer satisfying 0

[0043] In a possible implementation, the third threshold and / or the fourth threshold is specified by a protocol, or determined by configuration information of the second communication device, or determined by configuration information of the first communication device.

At this time, the K-N+1 can be understood as the fourth threshold, that is, the fourth threshold can be calculated by the configured K and N.

[0046] Optionally, the fourth threshold can also be directly determined by the first communication device and / or the second communication device according to the configured information, for example, for the first reference signal with the Nth (N is an integer satisfying 0 < N ≤ K) signal quality in the K first reference signals, if the number of the first reference signals in the first reference signal set is greater than or equal to N, it is determined to trigger the beam measurement reporting.

[0111] In order to make the purposes, technical solutions and advantages of the present application clearer, the embodiments of the present application will be described below with reference to the drawings.

[0112] The terms "first" and "second" and the like in the specification of the present application, claims, and drawings are used to distinguish different objects, and are not used to describe a particular order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device, etc. including a series of steps or units is not limited to the listed steps or units, but can optionally include other steps or units not listed, or can optionally include other steps or units inherent to the process, method, product, or device, etc.

[0113] In this document, "embodiment" means that the specific features, structures, or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment is referred to, nor does it mean that independent or alternative embodiments are mutually exclusive or alternative to each other. It is explicitly and implicitly understood by those skilled in the art that, unless otherwise specified and logically contradictory, the terms and / or descriptions between various embodiments of the present application are consistent and can be mutually referred to, and the technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0114] It should be understood that in the present application, "at least one" means one or more, "multiple" means two or more, "at least two" means two or three and more, and "and / or" is used to describe the association between the associated objects, which means that there can be three relationships, for example, "A and / or B" can mean that there are three cases of only A, only B, and A and B at the same time, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple items. For example, at least one of a, b, or c can mean a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0115] It should be noted that in this application, "indication" can include direct indication, indirect indication, display indication, and implicit indication. When describing that certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0116] In this application, the information indicated by the indication information is referred to as the to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, but not limited to, the to-be-indicated information can be directly indicated, such as the to-be-indicated information itself or the index of the to-be-indicated information. The to-be-indicated information can also be indirectly indicated by indicating other information, where the other information and the to-be-indicated information have an association relationship. The to-be-indicated information can also be indicated only by a part, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, the protocol stipulates), thereby reducing the indication overhead to a certain extent. The to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending time of these sub-information can be the same or different. The specific sending method is not limited in this application. The sending period and / or sending time of these sub-information can be pre-defined, for example, pre-defined according to the protocol, or configured by the transmitting end device by sending configuration information to the receiving end device.

[0117] It should be noted that in this application, "sending" can be understood as "output", and "receiving" can be understood as "input". "Sending information to A", where "to A" only indicates the direction of information transmission, and A is the destination, does not limit that "sending information to A" must be direct sending on the air interface. "Sending information to A" includes directly sending information to A, and also includes indirectly sending information to A through a transmitter, so "sending information to A" can also be understood as "outputting information to A". Similarly, "receiving information from A" indicates that the source of the information is A, which includes directly receiving information from A, and also includes indirectly receiving information from A through a receiver, so "receiving information from A" can also be understood as "inputting information from A".

[0118] The method provided by the present application can be applied to various communication systems, for example, it can be an internet of things (IoT) system, a narrow band internet of things (NB-IoT) system, a long term evolution (LTE) system, or a 5th-generation (5G) communication system, and a new communication system (such as 6G) that appears in future communication development.

The IoT network may, for example, include a vehicle network. In the vehicle network system, the communication modes are collectively referred to as vehicle-to-everything (V2X, X may represent any thing), for example, the V2X may include vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, or vehicle-to-network (V2N) communication, and the like. For example, in the diagram 1 shown below, the terminal devices can communicate with each other through D2D technology, M2M technology, or V2X technology, and the like.

[0124] In some deployments, a base station (such as a gNB) can be composed of a centralized unit (CU) and a distributed unit (DU). That is, the functions of the base station in the access network are split, and part of the functions of the base station are deployed in a CU, and the remaining functions are deployed in a DU. And multiple DUs share one CU, which can save costs and facilitate network expansion. In some other deployments of the base station, the CU can also be divided into a CU-control plane (CP) and a CU-user plane (UP), etc. In some other deployments of the base station, the base station can also be a radio unit (RU), etc. In some other deployments of the base station, the base station can also be an open radio access network (ORAN) architecture, etc. The specific type of the base station is not limited in the present application. Exemplarily, when the base station is an ORAN architecture, the base station shown in the embodiments of the present application can be an access network device in the ORAN, or a module in the access network device, etc. In the ORAN system, the CU can also be referred to as an open (O)-CU, the DU can also be referred to as an O-DU, the CU-DU can also be referred to as an O-CU-DU, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an O-RU.

[0128] For ease of description, hereinafter, the terminal device will be taken as a UE as an example to introduce the method involved in the present application.

[0129] As shown in FIG. 1, the communication system can also include at least one core network device. The core network device is introduced as follows:

[0130] Exemplarily, the core network device includes user access control, mobility management, session management, user security authentication, billing and other services. It is composed of multiple functional units, which can be divided into control plane and data plane functional entities. Among them, the access and mobility management unit (AMF) is responsible for user access management, security authentication, and mobility management. The location management unit (LMF) is responsible for managing and controlling the positioning service request of the target terminal and processing positioning related information. The user plane unit (UPF) is responsible for managing the transmission of user plane data, traffic statistics and other functions.

[0131] In the communication system shown in FIG. 1, there are one core network device, two base stations and eight UEs, such as the core network device, base station 1 and base station 2, and UE1 to UE8 in FIG. 1. In the communication system, base station 1 can send downlink signals such as configuration information or downlink control information (DCI) to UE1 to UE6, and UE1 to UE6 can send uplink signals such as SRS or physical uplink shared channel (PUSCH) to base station 1. Base station 1 can also send downlink signals to UE7 to UE8 through base station 2, and UE7 to UE8 can send uplink signals to base station 1 through base station 2. Base station 2 can send downlink signals such as configuration information or DCI to UE7 to UE8, and UE7 to UE8 can send uplink signals such as SRS or PUSCH to base station 2. It can be understood that for the communication mode between UEs, reference can be made to the description above, which will not be described in detail here.

[0132] It should be understood that FIG. 1 exemplarily shows one core network device, two base stations and eight UEs, and the communication links between the communication devices. Alternatively, the communication system can include multiple base stations, and each base station can include other numbers of UEs in its coverage range, such as more or less UEs, etc., which are not limited in the present application.

The multiple antennas can include at least one transmitting antenna for transmitting signals and at least one receiving antenna for receiving signals, and the like, and the specific structure of each communication device is not limited in the embodiments of the present application. Alternatively, the communication system can also include a network controller, a mobile management entity and other network entities, which are not limited in the embodiments of the present application.

[0134] It can be understood that the communication system diagram shown in FIG. 1 is only an example, and for other forms of communication system diagrams, reference can be made to relevant standards or protocols, etc., which will not be described one by one here.

[0135] The various embodiments shown below can be applicable to the communication system shown in FIG. 1, and can also be applicable to other forms of communication systems, for which the following will not be described again.

[0136] The present application provides a communication method, which is applied to the field of communication technology, such as communication in the beam measurement reporting scenario. In order to more clearly describe the scheme of the present application, some knowledge related to beam measurement reporting will be introduced first.

[0137] Channel state information (channel state information, CSI) in the field of wireless communication refers to the channel properties of a communication link. It describes the attenuation factors of signals on each transmission path, i.e., the value of each element in the channel gain matrix H, such as signal scattering, environmental attenuation (multipath fading or shadowing fading), distance attenuation (power decay of distance), etc. CSI can make the communication system adapt to the current channel conditions and provide high reliability and high rate communication in a multi-antenna system.

[0138] Multiple input multiple output (multiple input multiple output, MIMO) technology is an antenna system that uses multiple antennas at the transmitting end and the receiving end to form multiple channels between the transmitting and receiving ends, in order to improve channel capacity. When a base station transmits data to a UE using MIMO technology, it needs to rely on the reference signal measurement results (which can also be understood as CSI measurement results) fed back by the UE.

[0139] Therefore, the reference signal measurement (which can also be understood as CSI measurement) between the base station and the UE is crucial to the transmission performance of the MIMO system.

[0140] The basic process of CSI measurement is as follows:

[0141] The base station needs to first send channel measurement configuration information to the UE for channel measurement configuration, informing the UE of the time and behavior of channel measurement; then the base station sends a channel measurement pilot signal to the UE for channel measurement; the UE performs CSI measurement according to the channel measurement pilot signal sent by the base station, obtains the CSI measurement result, and reports the CSI measurement result to the base station; the base station determines the precoding information of the service data transmission according to the CSI measurement result reported by the UE, and then transmits the service data.

[0142] The CSI measurement result reported by the UE can include multiple information, such as but not limited to a rank indicator (RI), a channel quality indicator (CQI), a precoding matrix indicator (PMI), and the like. The present application does not limit this.

[0143] Correspondingly, the base station can determine the number of streams for transmitting data to the UE according to the RI fed back by the UE, determine the modulation order and the code rate of channel coding for transmitting data to the UE according to the CQI fed back by the UE, and determine the precoding for transmitting data to the UE according to the PMI fed back by the UE.

[0144] Optionally, one or more of the channel measurement configuration information, the channel measurement pilot signal, the CSI measurement result, and the service data can be transmitted through one or more of a radio resource control (RRC) message, a media access control-control element (MAC CE), downlink control information (DCI), and a physical downlink shared channel (PDSCH).

[0145] It should be understood that the above transmission manners are only exemplary and illustrative, and should not be construed as limiting the embodiments of the present application. Embodiments based on supplements or reasonable modifications of the above transmission manners are also within the scope of protection of the embodiments of the present application.

[0146] However, the accuracy of the beam measurement result triggered by the reference signal measurement result is low, which misleads the network side to perform incorrect operations based on the beam measurement result.

[0147] In view of this, in the embodiments of the present application, a new communication method is provided, which can improve the accuracy of the reported beam measurement result to effectively assist the network side to perform correct operations.

[0148] Please refer to FIG. 2, which is a flowchart of a communication method provided by the embodiments of the present application. The communication method is applied to the field of communication technology, such as communication in the scenario of beam measurement reporting. It can be understood that the communication method can be executed by a communication device, which can be a network device and / or a terminal device, or a chip (system) or circuit for the network device and / or the terminal device, and the present application does not limit this.

[0158] Optionally, the measurement order between the K first reference signals and the L second reference signals can be random, and there is no priority, and the embodiments of the present application do not limit this.

[0159] S203: The first communication device obtains a measurement result corresponding to each of the K first reference signals based on the first measurement result.

[0160] Optionally, the measurement result corresponding to each of the K first reference signals obtained based on the first measurement result can include one measurement result corresponding to one measurement of each first reference signal, can include a plurality of measurement results corresponding to a plurality of measurements of each first reference signal, and can also include one measurement result calculated according to the plurality of measurement results, and the embodiments of the present application do not limit this.

[0162] It can be understood that the measurement result corresponding to each of the K first reference signals includes one or more measurement results corresponding to each first reference signal, and specifically can include one or more RSRP corresponding to each first reference signal and is determined by one or more RSRP corresponding to each first reference signal.

[0163] Optionally, the measurement result corresponding to each of the K first reference signals can be obtained by an average or weighted average or other calculation method of one or more RSRP corresponding to each first reference signal, and the embodiments of the present application do not limit this.

[0164] Optionally, the RSRP can also be replaced by a signal to interference plus noise ratio (SINR), a reference signal receiving quality (RSRQ), a received signal strength indication (RSSI), and the like, and the embodiments of the present application do not limit this.

[0165] Through the embodiments of the present application, the inaccuracy caused by the fluctuation of the measurement result corresponding to the reference signal with time can be reduced or even eliminated, so that the accuracy of the reported beam measurement result can be improved, thereby effectively assisting the network side to perform correct operation.

[0166] S204: The first communication device obtains, based on the first measurement result and the second measurement result, a number of the first event corresponding to each pair of reference signals in the K*L pairs of reference signals.

[0167] The first event includes a difference between one measurement result corresponding to one of the L second reference signals and one measurement result corresponding to one of the K first reference signals being greater than a first threshold value.

[0168] Optionally, the first threshold value can be specified by a protocol, or can be configured by the second communication device, or can be determined autonomously by the first communication device, and embodiments of the present application do not limit this.

[0169] It can be understood that the first threshold value can be adjusted according to the communication requirements of different application scenarios, and embodiments of the present application do not limit this.

[0170] Optionally, the first event can also be referred to as "event-7", and embodiments of the present application do not limit the specific name of the first event.

[0171] Optionally, the execution order of steps S203 and S204 can be random, and there is no priority, and embodiments of the present application do not limit this.

[0172] S205: The first communication device determines to trigger beam measurement reporting based on the measurement result corresponding to each of the K first reference signals and / or the number of the first event corresponding to each pair of reference signals in the K*L pairs of reference signals.

[0173] It can be understood that the first communication device can determine to trigger beam measurement reporting based on one or more of the measurement result corresponding to each of the K first reference signals and the number of the first event corresponding to each pair of reference signals in the K*L pairs of reference signals.

[0174] Optionally, the first communication device determining to trigger beam measurement reporting can specifically include but is not limited to the following implementation manners:

[0175] Manner one:

[0176] The K first reference signals are sorted in descending order according to the measurement result corresponding to each first reference signal.

[0177] If the number of the first event corresponding to the first pair of reference signals in the K*L pairs of reference signals is greater than or equal to a second threshold value, the first communication device triggers beam measurement reporting.

[0178] The first pair of reference signals includes a reference signal A and a reference signal B, the reference signal A is a first reference signal ranked at an Mth position in the K first reference signals, M is an integer satisfying 0 < M ≤ K, and the reference signal B is one of the L second reference signals.

[0179] Optionally, the second threshold value can be specified by a protocol, or can be configured by the second communication device, or can be autonomously determined by the first communication device, and embodiments of the present application do not limit this.

[0180] It can be understood that the second threshold value can be adjusted according to the communication requirements of different application scenarios, and embodiments of the present application do not limit this.

[0181] It can be understood that for the first reference signal ranked at the Mth position in the K first reference signals (assuming it is a reference signal A), if the number of first events between one second reference signal (assuming it is a reference signal B) and the first reference signal is greater than or equal to the second threshold value, it is determined to trigger beam measurement reporting.

[0182] Compared with the current method of triggering beam measurement reporting only when the measurement result of the reference signal corresponding to the non-activated beam is higher than the measurement result of the reference signal corresponding to the activated beam, and the difference is greater than a threshold, the embodiments of the present application determine to trigger beam measurement reporting based on the measurement result corresponding to each of the K first reference signals and the number of first events corresponding to each pair of reference signals in the K×L pairs of reference signals. It can reduce or even eliminate the inaccuracy caused by the fluctuation of the measurement result corresponding to the reference signal over time, thereby improving the accuracy of the reported beam measurement result, and effectively assisting the network side to perform correct operations.

[0183] Method two:

[0184] Based on the number of first events corresponding to each pair of reference signals in the K×L pairs of reference signals, the maximum number of L numbers of first events corresponding to each of the K first reference signals is obtained.

[0185] If there is a first reference signal set in the K first reference signals, beam measurement reporting is triggered.

[0186] The maximum number of L numbers of first events corresponding to each first reference signal in the first reference signal set is greater than or equal to a third threshold value, and the number of first reference signals in the first reference signal set is greater than or equal to a fourth threshold value.

[0187] Optionally, the third threshold and / or the fourth threshold can be specified by a protocol, or can be determined by configuration information of the second communication device, or can be determined by configuration information of the first communication device, and the embodiments of the present application do not make any limitation in this regard.

[0188] It can be understood that the third threshold and / or the fourth threshold can be adjusted according to the communication requirements of different application scenarios, and the embodiments of the present application do not make any limitation in this regard.

[0189] Optionally, the fourth threshold can be calculated by the first communication device and / or the second communication device according to the configured information, for example, for the first reference signal with the Nth (N is an integer satisfying 0 < N ≤ K) signal quality in the K first reference signals, if the number of the first reference signals in the first reference signal set is N-1, and the N-1 is greater than or equal to K-N+1, it is determined to trigger the beam measurement reporting. At this time, the K-N+1 can be understood as the fourth threshold, that is, the fourth threshold can be calculated by the configured K and N.

[0190] Optionally, the fourth threshold can also be directly determined by the first communication device and / or the second communication device according to the configured information, for example, for the first reference signal with the Nth (N is an integer satisfying 0 < N ≤ K) signal quality in the K first reference signals, if the number of the first reference signals in the first reference signal set is greater than or equal to N, it is determined to trigger the beam measurement reporting. At this time, the N can be understood as the fourth threshold, that is, the fourth threshold can be directly determined by the configured N.

[0191] It can be understood that, for the first reference signal with the Nth (N is an integer satisfying 0 < N ≤ K) signal quality in the K first reference signals, if the number of the first reference signals in the first reference signal set is N-1, and the N-1 is greater than or equal to K-N+1 (the K-N+1 can be understood as the fourth threshold), it is determined to trigger the beam measurement reporting.

[0192] Compared with the current method of triggering beam measurement reporting only when the measurement result of the reference signal corresponding to the unactivated beam is higher than the measurement result of the reference signal corresponding to the activated beam, and the difference is greater than a threshold, the embodiments of the present application determine to trigger the beam measurement reporting based on the number of the KxL first events corresponding to each pair of reference signals in the reference signal, which can reduce or even eliminate the inaccuracy caused by the fluctuation of the measurement result of the reference signal over time, thereby improving the accuracy of the reported beam measurement result, and effectively assisting the network side to perform correct operations.

[0193] It should be understood that the above-mentioned manner one and manner two are only exemplary descriptions of the determination of the first communication device to trigger the reporting of the beam measurement, and should not be construed as limiting the embodiments of the present application.

[0194] It should be understood that the new embodiments obtained based on the reasonable deformation or supplement of the above-mentioned manner one and / or manner two all belong to the protection scope of the present application.

[0195] S206: The first communication device sends the beam measurement report to the second communication device, and correspondingly, the second communication device receives the beam measurement report.

[0196] S207: The second communication device updates the transmission configuration indication information corresponding to the K first reference signals.

[0197] The above-mentioned updating of the transmission configuration indication information corresponding to the K first reference signals can replace one or more first reference signals in the K first reference signals with one or more second reference signals with better quality in the above-mentioned L second reference signals, so as to improve the transmission efficiency of the data transmission between the first communication device and the second communication device by using the updated K first reference signals corresponding to the beams.

[0198] Optionally, the transmission configuration indication information corresponding to the K first reference signals can specifically include one or more activated transmission configuration indicator states (activated TCI states). The activated TCI state refers to the TCI state activated by the network side for the UE through the MAC CE for the PDSCH. Each activated TCI state is associated with a downlink (DL) transmission beam. The network side can indicate a TCI state for the UE from the activated TCI states through the DCI, indicating that the network side uses the downlink transmission beam associated with the TCI state to transmit the PDSCH scheduled by the DCI.

[0199] Currently, as long as the measurement result of the reference signal corresponding to the unactivated beam is higher than the measurement result of the reference signal corresponding to the activated beam, and the difference is higher than a threshold, the beam measurement reporting is triggered. However, the measurement result corresponding to the reference signal fluctuates greatly over time, and the measurement result at a certain moment cannot fully reflect the quality of the reference signal. For example, the Mth best activated TCI state determined at a previous measurement moment may be different from the Mth best activated TCI state determined at a subsequent measurement moment. Therefore, according to the current triggering mechanism of the beam measurement reporting, the accuracy of the beam measurement result triggered for reporting is low, thereby misleading the network side to perform incorrect operations based on the beam measurement result.

[0200] In the embodiments of the present application, the second communication device sends K first reference signals and L second reference signals to the first communication device. Correspondingly, the first communication device receives the K first reference signals and the L second reference signals from the second communication device. The first communication device measures the K first reference signals to obtain first measurement results, and measures the L second reference signals to obtain second measurement results. The first communication device obtains the measurement result corresponding to each of the K first reference signals based on the first measurement results, and obtains the number of first events corresponding to each of the K*L pairs of reference signals based on the first measurement results and the second measurement results. The first communication device determines to trigger the beam measurement reporting based on the measurement result corresponding to each of the K first reference signals and / or the number of first events corresponding to each of the K*L pairs of reference signals, and reports the measurement results to the second communication device. Correspondingly, the second communication device receives the beam measurement reporting, and updates the transmission configuration indication information corresponding to the K first reference signals based on the beam measurement reporting.

[0201] Through the embodiments of the present application, the determination of triggering the beam measurement reporting based on the measurement result corresponding to each of the K first reference signals and / or the number of first events corresponding to each of the K*L pairs of reference signals can reduce or even eliminate the inaccuracy caused by the fluctuation of the measurement result corresponding to the reference signal over time, thereby improving the accuracy of the reported beam measurement result, effectively assisting the network side to perform correct operations, and updating the transmission configuration indication information corresponding to the K first reference signals in time.

[0202] In a possible embodiment, the K first reference signals include at least one reference signal corresponding to a first beam, and the L second reference signals include at least one reference signal corresponding to a second beam.

[0203] The first beam is a beam that is not used for current data transmission between the first communication device and the second communication device, and the second beam is an inactivated beam.

[0204] It can be understood that the first beam is a beam that is not used for current data transmission between the first communication device and the second communication device but is activated. Alternatively, the first beam can be referred to as an “active beam”, and the specific name of the first beam is not limited in the embodiments of the present application.

[0205] It can be understood that the second beam is a beam that is not used for current data transmission between the first communication device and the second communication device and is inactivated. Alternatively, the second beam can be referred to as a “new beam”, and the specific name of the second beam is not limited in the embodiments of the present application.

[0206] Through the beam measurement reporting triggering mechanism in the embodiments of the present application, when it is determined to trigger beam measurement reporting, one or more beams that are not used for current data transmission between the first communication device and the second communication device but are activated (i.e., the first beam described above) can be effectively replaced by one or more beams that are not used for current data transmission between the first communication device and the second communication device and are inactivated and have better quality (i.e., the second beam described above) based on the reported measurement results, so as to improve the data transmission efficiency between the first communication device and the second communication device.

[0207] In a possible embodiment, the number of times of the first event corresponding to each pair of reference signals in the K*L pairs of reference signals obtained in the step S204 is located within a first time window, and the measurement result corresponding to each of the K first reference signals obtained in the step S203 is located within a second time window.

[0208] The first time window and the second time window can be the same or overlap.

[0209] Alternatively, the first time window and the second time window can be completely the same.

[0210] Alternatively, the first time window contains the second time window.

[0211] Alternatively, the second time window contains the first time window.

[0212] Alternatively, the first time window and the second time window partially overlap, and the first time window is after the second time window.

[0213] Alternatively, the first time window and the second time window partially overlap, and the first time window is before the second time window.

[0214] It can be understood that the specific relationship between the first time window and the second time window is not limited in the embodiments of the present application.

[0215] Optionally, the second time window can also be a time window corresponding to measurement of the L second reference signals, or the time window corresponding to measurement of the L second reference signals can also be another time window, and the embodiments of the present application do not make any limitation in this regard.

[0224] wherein the K activated TCI states are associated with downlink reference signals (DL RSs) corresponding to the active beams, and the L new beams are associated with DL RSs corresponding to the new beams.

[0225] Optionally, the activated TCI states can be numbered as active beam#k (k = 1, 2, …, K, K is an integer greater than 0), and the active beams can be numbered as active beam#k (k = 1, 2, …, K, K is an integer greater than 0).

[0226] Optionally, the new beams can be numbered as new beam#l (l = 1, 2, …, L, L is an integer greater than 0).

[0228] Step 2: For each pair {active beam#k, new beam#l}, the number D of Event-7 occurring within a time / quantity window W0 is counted k,l .

[0229] wherein if L1-RSRP of new beam#l - L1-RSRP of active beam#k > threshold, it is recorded as once Event-7.

[0230] Optionally, the number of Event-7 corresponding to each pair {active beam#k, new beam#l} in this step 2 can refer to the description of step S204 in the embodiment shown in FIG. 2, which will not be described here.

[0231] Optionally, the Event-7 in this step 2 can refer to the description of the first event in the embodiment shown in FIG. 2, which will not be described here.

[0232] Step 3: For each active beam#m, the average value or weighted average value P of one or more L1-RSRP measurements measured within a time / quantity window W1 is calculated m , and the average L1-RSRP of all active beams is sorted in descending order.

[0240] Optionally, the method of triggering beam measurement reporting in this step 4 can refer to the description of method one in the embodiment shown in FIG. 2 above, which will not be repeated here.

[0241] Currently, as long as the measurement result of the reference signal corresponding to the unactivated beam is higher than the measurement result of the reference signal corresponding to the activated beam by a threshold, beam measurement reporting is triggered. However, the measurement result corresponding to the reference signal fluctuates greatly over time, and the measurement result at a certain moment cannot fully reflect the quality of the reference signal. For example, the Mth best activated TCI state determined at the previous measurement moment may be different from the Mth best activated TCI state determined at the next measurement moment. Therefore, according to the current triggering mechanism of beam measurement reporting, the accuracy of the beam measurement result triggering reporting is low, which misleads the network side to perform incorrect operations based on the beam measurement result.

[0242] And through the embodiments of the present application, based on the measurement results corresponding to each active beam and the number of Event-7 corresponding to each pair {active beam#k, new beam#l}, the triggering of beam measurement reporting can determine the quality of activated TCI states and more accurately determine the Mth best activated TCI state, avoiding the network side making wrong activated TCI states update caused by UE autonomous determination of the best activated TCI state, and then affecting the performance of beam management and user experience.

[0243] The present application also provides a communication method. It can be understood that the steps of the communication method in the embodiments of the present application can be regarded as reasonable deformation or supplement of the above-mentioned embodiments of FIG. 2; or it can be understood that the communication method in the embodiments of the present application can also be regarded as an independently executable embodiment, and the present application does not limit this.

[0254] Optionally, the Event-7 in this step 2 can refer to the description of the first event in the embodiment shown in FIG. 2, which will not be repeated here.

[0255] Optionally, the time / quantity window W0 in this step 2 can refer to the description of the first time window in the embodiment shown in FIG. 2, which will not be repeated here.

[0256] Step 3: Within a time / quantity window W0, for each active beam#k, determine D k = max{D k,1 ,D k,2 ,…,D k,L}.

[0258] For the active beam#k0 located at the Nth position (N is an integer satisfying 0 < N ≤ K), if the number of active beams of ≥ (K-N+1) triggers beam measurement reporting.

[0259] Wherein, D THThe protocol can be agreed upon, or configured by the network side, or determined by the UE, and the embodiments of the present application do not limit this.

[0260] Optionally, the method of triggering beam measurement reporting in step 3 can refer to the description of method two in the embodiment shown in FIG. 2, which will not be repeated here.

[0261] Currently, as long as the measurement result of the reference signal corresponding to the unactivated beam is higher than the measurement result of the reference signal corresponding to the activated beam, and is higher than a threshold, the beam measurement reporting is triggered. However, the measurement result corresponding to the reference signal fluctuates greatly with time, and the one-time measurement result at a certain moment cannot fully reflect the quality of the reference signal. For example, the Nth best activated TCI state determined at the previous measurement moment may be different from the Nth best activated TCI state determined at the next measurement moment. Therefore, according to the current triggering mechanism of beam measurement reporting, the accuracy of the triggered beam measurement result is low, which misleads the network side to perform incorrect operations based on the beam measurement result.

[0262] According to the embodiments of the present application, the number of Event-7 corresponding to each pair {active beam#k, new beam#l} and the maximum number of L times of Event-7 corresponding to each active beam are used to determine the triggering of beam measurement reporting. The quality of the activated TCI state and the Nth best activated TCI state can be determined more accurately, which avoids the network side from making incorrect activated TCI state updates due to the UE autonomously determining the best activated TCI state, and further affects the performance of beam management and user experience.
