By utilizing antenna arrays and signal processing algorithms, beamforming technology enables directional transmission and signal enhancement, thereby improving the reliability and transmission rate of wireless communications.

[0007] In this embodiment, the first information may indicate relevant information of one or more beams. The terminal device measures one or more beams based on the transmit power indication information of one or more beams indicated by the first information to generate measurement results of the beams. The measurement results of the beams may indicate the overall measurement results of one beam or multiple beams over a period of time, which may improve the accuracy of the beam measurement and facilitate the network device to dynamically adjust the beam and its transmit power based on the beam measurement results, thereby improving the system communication performance.

[0075] In the embodiments of the present application, "protocol" may refer to a standard protocol in the field of communications, for example, it may include an LTE protocol, a NR protocol, and related protocols used in future communication systems, and this application does not limit this.
[0076] In order to better understand the technical solution provided by this application, the communication system architecture of this application is first described below.
[0077] Referring to FIG. 1 , FIG. 1 exemplarily shows an architecture diagram of a communication system provided in an embodiment of the present application.
[0078] As shown in Figure 1, the communication system 100 includes: a terminal device 101 and a network device 102, and the terminal device 101 communicates with the network device 102. The network device 102 includes an access network device 1021 and a core network device 1022, and the terminal device 101 can communicate with the core network device 1022 through the access network device 1021.
[0079] The terminal device 101 may also be referred to as a terminal, and may be a device with wireless transceiver capabilities. It may be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it may also be deployed on water (such as a ship); it may also be deployed in the air (such as an airplane, balloon, or satellite). The terminal device may be user equipment (UE), where UE includes a handheld device, vehicle-mounted device, wearable device, or computing device with wireless communication capabilities.
[0080] Exemplarily, the terminal device 101 may be a mobile phone, a tablet computer, or a computer with wireless transceiver capabilities. The terminal device may also be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like. In the embodiments of the present application, the device for implementing the function of the terminal may be a terminal; or it may be a device that can support the terminal to implement the function, such as a chip system, which may be installed in the terminal.
[0081] The access network (RAN) device 1021 is an intermediate device that connects terminal devices to core network devices via wireless communication. It is primarily responsible for radio resource management, quality of service (QoS) management, data compression and encryption, etc. on the air interface side. For example, the access network device 1021 can be a base station NodeB, an evolved base station eNodeB, a base station in a 5G mobile communication system or a next-generation radio (NR) communication system, or a base station in a future mobile communication system.
[0082] The core network (CN) device 1022 may include a user plane function (UPF) network element, an access and mobility management function (AMF) network element, a session management function (SMF) network element, a policy control function (PCF) network element, etc. In the embodiment of the present application, the device for implementing the function of the network device may be a network device, or a device capable of supporting the network device to implement the function, such as a chip system, which may be installed in the network device.
[0083] The technical solution provided in this application can be applied to the Long Term Evolution (LTE) architecture, and can also be applied to the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (UTRAN) architecture, or the Global System for Mobile Communication (GSM) / Enhanced Data Rate for GSM Evolution (EDGE) system radio access network (GSM EDGE Radio Access Network, GERAN) architecture.
[0084] The technical solution provided by this application can also be applied to any other wireless communication systems with similar structures and functions, such as Public Land Mobile Network (PLMN) system, fifth generation (5G) th Generation, 5G) communication systems (for example, new radio (NR) systems) and future mobile communication systems, etc., are not limited in any way in the embodiments of the present application.
[0085] In addition, the technical solutions provided in this application can also be applied to non-terrestrial network (NTN) systems such as satellite communication systems and high altitude platform station (HAPS) communications, for example, integrated communication and navigation (IcaN) systems and global navigation satellite systems (GNSS). Satellite communication systems can be integrated with traditional mobile communication systems.
[0086] Since traditional terrestrial networks cannot provide seamless coverage, especially in places where base stations cannot be deployed, such as the sea, desert, and air, satellite communications are considered an important direction for the future development of wireless communication technology.
[0087] Satellite communication refers to communications conducted by ground-based radio communication equipment using satellites as relays. The characteristics of satellite communication include a wide range, the ability to communicate between any two points within the range of the satellite's radio waves, and high reliability, which is less susceptible to land-based disasters.
[0088] As a supplement to the current terrestrial cellular communication system, satellite communication has the following advantages:
[0089] 1) Extended coverage: For areas that are not covered by current cellular communication systems or are costly to cover, such as oceans, deserts, and remote mountainous areas, satellite communications can be used to solve communication problems.
[0090] 2) Emergency communications: In extreme cases such as disasters (e.g., earthquakes), when the cellular communication system infrastructure is unavailable, satellite communications can be used to quickly establish communication connections.
[0091] 3) Provide industry applications: For example, for delay-sensitive services with long-distance transmission, satellite communications can be used to reduce the delay of service transmission.
[0092] 2 , which exemplarily shows an architecture diagram of a satellite communication system provided in an embodiment of the present application.
[0093] As shown in Figure 2, satellite 201 provides communication services to terminal device 202 via multiple beams. In this scenario, satellite 201 is a non-geostationary Earth orbit (NGEO) satellite. Satellite 201 is also connected to a ground base station 203, which can communicate with terminal device 202 via satellite 201. For example, when terminal device 202 sends data to ground base station 203 via satellite 201, this link is called an uplink. When ground base station 203 sends data to terminal device 202 via satellite 201, this link is called a downlink.
[0094] Satellites use multiple beams to cover their service areas, and different beams can communicate using at least one of time division multiplexing, frequency division multiplexing, and space division multiplexing. Satellites can also be satellite base stations or network-side equipment onboard satellites.
[0095] Time division multiplexing (TDM) involves using different time periods to transmit different signals. Frequency division multiplexing (FDM) divides the total bandwidth of a channel into multiple frequency bands, each capable of independently transmitting a single signal. Space division multiplexing (SDM) reuses the same frequency band in different locations. In mobile communications, this fundamental technology uses array antennas to achieve spatial separation, forming distinct beams in the direction of different users.
[0096] The satellite's transmission power directly determines the range and strength of its signal coverage. Generally speaking, the greater the transmission power, the wider the signal coverage and the higher the transmission quality. For typical satellites, transmission power typically ranges from tens to hundreds of watts. The satellite's transmission bandwidth determines the capacity and data transmission rate of the satellite communication system. The greater the bandwidth, the greater the amount of data that can be transmitted simultaneously and the faster the communication rate.
[0097] Currently, due to limitations on satellite transmit power and transmission bandwidth, satellites can only serve a portion of their coverage area during a given period, impacting the performance of communication systems. For example, referring to Figure 2, during a given period, a satellite can activate, for example, four beams. The area covered by these four beams constitutes the satellite's service area during that period. This means that a satellite typically cannot activate all beams at the same time. Activating a beam by a satellite means the satellite is transmitting downlink data via that beam.
[0098] Given this, how to enhance downlink coverage and improve communication system performance has become a hot topic in the industry. Dynamically sharing and allocating transmit power across different beams is an effective means of expanding satellite coverage and increasing satellite communication system capacity. In other words, by dynamically sharing power across different beams, the efficiency of satellite transmit power utilization can be improved, thereby increasing the overall throughput of the satellite communication system.
[0099] Dynamic power sharing between different beams means that the network dynamically allocates beams and / or shares transmit power across different beams based on the number of users and signal requirements within their coverage areas. The accuracy of beam measurement results affects the network's dynamic allocation and adjustment of beams. Therefore, improving the accuracy of terminal beam measurement is a pressing issue.
[0100] In response to the above problems, an embodiment of the present application proposes a communication method, in which the terminal device can dynamically monitor the beam based on the indication information sent by the network device (such as the first information in the embodiment below) to obtain the measurement results of the beam in a timely manner. The terminal device can promptly feed back the measurement results of the beam to the network device so that the network device can accurately adjust the beam and its transmission power based on the measurement results of the beam, thereby improving the resource utilization and communication quality of the system.
[0101] It should be noted that in the embodiments of the present application, the network device may be a satellite or a satellite base station or a network device on a satellite, or a network device in a traditional mobile communication system. The network device may refer to an access network device such as a base station.
[0102] In the embodiments of the present application, a beam specifically refers to a transmit beam. A beam can also be described as a spatial transmission filter, and the transmit power of a beam can also be described as the transmit power of the beam. In some embodiments, a beam can also be replaced by a reference signal corresponding to the beam, an indication of a beam can be described as an indication of a reference signal corresponding to the beam, and measurement of a beam can be described as measurement of the reference signal corresponding to the beam.
[0103] For the convenience of description, the following embodiments all use beams as an example to illustrate the solutions.
[0104] The technical solution of the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other. For the same or similar content, such as the explanation of terms or nouns, and the explanation of steps, etc., different embodiments can refer to each other and will not be repeated.
[0105] Referring to Figure 3, Figure 3 exemplarily shows a flow chart of a communication method provided in an embodiment of the present application. As shown in Figure 3, the communication method of this embodiment includes:
[0106] S301. The network device sends first information to the terminal device, where the first information is used to indicate beam-related information.
[0107] First, the content indicated by the first information is described in detail.
[0108] In some embodiments, the information related to the beam includes transmit power indication information of the beam. The transmit power indication information of the beam can also be described as transmit power indication information of the beam.
[0109] Optionally, the beam-related information may include transmit power indication information of one or more beams. For example, during a certain time period, the network device transmits downlink data through one or more beams, and the network device may send first information to the terminal device, where the first information is used to indicate the transmit power indication information of the one or more beams.
[0110] In some embodiments, the transmit power indication information of the beam includes transmit power value information of the beam.
[0111] In one example, the transmit power value of the beam may be indicated in an explicit manner, that is, the transmit power indication information of the beam includes the transmit power value of the beam. In this example, the transmit power value of the beam is the absolute value of the transmit power of the beam, in decibel milliwatts (dBm).
[0112] In one example, the transmit power value of a beam can be indicated implicitly, that is, the transmit power indication information of the beam includes an index value corresponding to the transmit power value of the beam, where the index value is used to indicate the transmit power value of the beam, or to indicate the interval in which the transmit power value of the beam lies. The index value and its corresponding transmit power value of the beam can be agreed upon by the protocol or configured by the network.
[0113] In this embodiment, after receiving the first information, the terminal device can obtain the transmission power value of one or more beams indicated by the network device, so that the terminal device can measure the one or more beams.
[0114] In some embodiments, the transmit power indication information of the beam may be the energy per resource element (EPRE) information of the beam. The EPRE information of the beam may be the absolute value of the transmit power of the beam (calculated using the formula 101g (power linear value / 1mW)), with the unit being decibel milliwatt (dBm). Alternatively, the EPRE information of the beam may be the offset value of the transmit power value of the beam relative to a certain reference transmit power value, with the unit being decibel (dB) (see Formula 1). dB =10lg(P i / P o ) Formula 1
[0115] Where N dB Indicates the decibel value of the transmit power value of a beam relative to a certain reference transmit power value, P i Indicates the transmit power value of a beam, P o Indicates a reference transmit power value, which can be a protocol agreement or a network configuration.
[0116] In this embodiment, after receiving the first information, the terminal device can obtain the transmission power values of one or more beams indicated by the network device through the transmission power offset value information of the beam, so that the terminal device can measure the one or more beams.
[0117] In some embodiments, the beam-related information may further include at least one of the following:
[0118] Indication information of the effective time of the transmission power indication information of the beam; indication information of the invalid time of the transmission power indication information of the beam; indication information of the effective duration of the transmission power indication information of the beam.
[0119] In one example, the beam-related information includes: information indicating the effective time of the beam's transmit power indication information. The effective time indication information includes an offset value of the effective time relative to the current time (hereinafter referred to as the effective time offset value).
[0120] For example, FIG4 illustrates a schematic diagram of the configuration of time domain resources in which the transmit power indication information of a beam takes effect. FIG4 uses a time slot as an example for illustration. In some embodiments, the time unit may also be a radio frame, a subframe, an orthogonal frequency division multiplexing (OFDM) symbol, etc.
[0121] Referring to Figure 4, if the first information indicates the transmission power value of beam 1 and the offset value K1, after the terminal device receives the first information in the nth time slot, the terminal device can measure beam 1 based on the power indicated by the first information starting from the n+K1th time slot.
[0122] In one example, if the offset value of the effective time of the transmission power indication information of the beam is agreed upon by the protocol, the relevant information of the beam includes indication information of the effective time length of the transmission power indication information of the beam.
[0123] In this example, the terminal device can measure the corresponding beam based on the power indicated by the first information within the effective duration starting from the effective moment, based on the effective duration of the transmit power indication information of the beam indicated in the first information and the offset value of the effective moment of the transmit power indication information of the beam agreed in the protocol.
[0124] In one example, if the offset value of the effective moment of the transmit power indication information of the beam is agreed upon by the protocol, the relevant information of the beam includes indication information of the invalid moment of the transmit power indication information of the beam.
[0125] In this example, the terminal device can determine the effective duration based on the offset value of the expiration time of the transmission power indication information of the beam indicated in the first information and the offset value of the effective time of the transmission power indication information of the beam agreed in the protocol, and then measure the corresponding beam based on the power indicated by the first information within the effective duration starting from the effective time.
[0126] In one example, the beam-related information includes: information indicating the effective time of the beam's transmit power indication information and information indicating the effective duration. The information indicating the effective time includes an offset value of the effective time, and the information indicating the effective duration includes the effective duration.
[0127] For example, continuing to refer to Figure 4, if the first information indicates the transmission power value of beam 1, the offset value K1 at the effective time, and the effective duration of m time slots, after the terminal device receives the first information in the nth time slot, the terminal device can measure beam 1 based on the power indicated by the first information within m time slots starting from the n+K1th time slot.
[0128] Optionally, the effective period can be agreed upon in the agreement.
[0129] In one example, the beam-related information includes: information indicating the time at which transmit power indication information of the beam takes effect and information indicating the time at which it fails to take effect. The information indicating the time at which the beam takes effect may include an offset value for the time at which the beam takes effect, and the information indicating the time at which the beam fails to take effect may include an offset value for the time at which the beam fails to take effect relative to the current time (hereinafter referred to as the offset value for the time at which the beam fails to take effect).
[0130] For example, continuing to refer to Figure 4, if the first information indicates the transmission power value of beam 1, the offset value K1 at the effective time, and the offset value K2 at the failure time, after the terminal device receives the first information in the nth time slot, the terminal device can measure the beam within the (K2-K1) time slot starting from the n+K1th time slot.
[0131] In one example, the relevant information of the beam includes: indication information of the expiration time of the beam's transmission power indication information and indication information of the validity period.
[0132] For example, continuing to refer to Figure 4, if the offset value of the expiration moment of the transmission power value of beam 1 indicated in the first information is K2, and the terminal device receives the first information in the nth time slot, the terminal device can know that the transmission power value of beam 1 begins to become invalid in the n+K2th time slot until the new first information again indicates the effective moment of the transmission power value of beam 1, or until the next effective period of the transmission power value of beam 1 begins.
[0133] In this example, the terminal device can determine the effective time of the transmit power indication information of the beam based on the offset value of the expiration time of the transmit power indication information of the beam indicated in the first information and the effective duration. Then, the terminal device can measure the corresponding beam based on the power indicated by the first information within the effective duration starting from the effective time.
[0134] In one example, the relevant information of the beam includes: indication information of the effective time of the beam's transmission power indication information, indication information of the effective time, and indication information of the expiration time.
[0135] In some embodiments, the beam-related information may further include a validity period of the beam's transmit power indication information. Referring to Figure 4 , the validity period of the beam's transmit power indication information may be K3 time slots.
[0136] Next, the carrying method of the first information is explained.
[0137] In some embodiments, the first information includes at least one of the following: system information block (SIB); radio resource control (RRC) signaling; control element (CE) of medium access control (MAC); downlink control information (DCI).
[0138] (1) The network device may send one of the above-mentioned first information to indicate beam-related information. This will be described below through several embodiments.
[0139] In some embodiments, the network device sends an SIB to the terminal device, the SIB including first information, the first information being used to indicate beam-related information. This embodiment can also be described as: the network device sends an SIB to the terminal device, the SIB being used to indicate beam-related information.
[0140] In some embodiments, the network device sends RRC signaling to the terminal device, the RRC signaling including first information, the first information being used to indicate beam-related information. This embodiment can also be described as: the network device sends RRC signaling to the terminal device, the RRC signaling being used to indicate beam-related information.
[0141] In some embodiments, the network device sends a MAC CE to the terminal device, where the MAC CE includes first information, where the first information is used to indicate beam-related information. This embodiment can also be described as: the network device sends a MAC CE to the terminal device, where the MAC CE is used to indicate beam-related information.
[0142] In some embodiments, the network device sends a DCI to the terminal device, where the DCI includes first information, and the first information is used to indicate beam-related information. This embodiment can also be described as: the network device sends a DCI to the terminal device, where the DCI is used to indicate beam-related information.
[0143] In one example, the DCI is a first DCI, which refers to a group DCI. The network device sends the first DCI to the terminal device, where the first DCI includes first information, where the first information is used to indicate relevant information of one or more beams.
[0144] This example can also be described as: the first information is the first DCI, the first DCI is used to indicate relevant information of one or more beams, and the first DCI corresponds to one or more terminal devices in the same group.
[0145] For example, taking the case where beam-related information includes beam transmit power indication information, group A includes terminal device 1, terminal device 2, and terminal device 3. The network device sends group DCI to the terminal devices in group A via multicast. The group DCI is used to indicate relevant information of the three beams, such as transmit power indication information for beam 1, beam 2, and beam 3. Beam 1 corresponds to terminal device 1, and the network device sends signaling or data to terminal device 1 via beam 1. Beam 2 corresponds to terminal device 2, and the network device sends signaling or data to terminal device 2 via beam 2. Beam 3 corresponds to terminal device 3, and the network device sends signaling or data to terminal device 3 via beam 3.
[0146] In this example, the network device sends relevant information of one or more beams to the terminal devices in the group through the group DCI, indicating the relevant information of the beams of the terminal devices in the group so that the terminal devices in the group can perform beam measurements separately.
[0147] In another example, the DCI is a second DCI, which refers to a UE-specific DCI. The network device sends the second DCI to the terminal device, where the second DCI includes first information, where the first information is used to indicate relevant information of one or more beams.
[0148] This example can also be described as: the first information is the second DCI, the second DCI is used to indicate relevant information of one or more beams, and the second DCI corresponds to a terminal device.
[0149] In this example, the network device sends relevant information of one or more beams to a specific terminal device through UE-specific DCI, indicating the relevant information of the beam of the specific terminal device so that the terminal device can measure the one or more beams.
[0150] (2) The network device may send two or more types of information in the above-mentioned first information to jointly indicate the relevant information of the beam.
[0151] Joint indication may refer to indicating different information in the relevant information of the beam through two or more types of information.
[0152] For ease of understanding, the following describes a solution using two types of information to jointly indicate beam-related information from a network device.
[0153] For example, taking the case where the relevant information of a beam includes the transmit power indication information of the beam and the indication information of the effective time, and the two types of information jointly indicated are SIB and RRC signaling, in one example, the network device may indicate the transmit power indication information of the beam by sending an SIB, and indicate the indication information of the effective time of the transmit power indication information of the beam by sending RRC signaling. In another example, the network device may indicate the indication information of the effective time of the transmit power indication information of the beam by sending an SIB, and indicate the transmit power indication information of the beam by sending RRC signaling.
[0154] For example, taking the case where the relevant information of a beam includes the transmit power indication information of the beam and the indication information of the effective time, and the two types of information jointly indicated are SIB and MAC CE, in one example, the network device may indicate the transmit power indication information of the beam by sending an SIB, and indicate the indication information of the effective time of the transmit power indication information of the beam by sending a MAC CE. In another example, the network device may indicate the indication information of the effective time of the transmit power indication information of the beam by sending an SIB, and indicate the transmit power indication information of the beam by sending a MAC CE.
[0155] For example, taking the case where the relevant information of a beam includes the transmit power indication information of the beam and the indication information of the effective time, and the two types of information jointly indicated are SIB and DCI, in one example, the network device may indicate the transmit power indication information of the beam by sending an SIB, and indicate the indication information of the effective time of the transmit power indication information of the beam by sending a DCI. In another example, the network device may indicate the indication information of the effective time of the transmit power indication information of the beam by sending an SIB, and indicate the transmit power indication information of the beam by sending a DCI.
[0156] For example, taking the case where the relevant information of a beam includes the transmit power indication information of the beam and the indication information of the effective time, and the two types of information jointly indicated are MAC CE and RRC signaling, in one example, the network device may indicate the transmit power indication information of the beam by sending a MAC CE, and indicate the indication information of the effective time of the transmit power indication information of the beam by sending RRC signaling. In another example, the network device may indicate the indication information of the effective time of the transmit power indication information of the beam by sending a MAC CE, and indicate the transmit power indication information of the beam by sending RRC signaling.
[0157] For example, taking the case where the relevant information of a beam includes the transmit power indication information of the beam and the indication information of the effective time, and the two types of information jointly indicated are MAC CE and DCI, in one example, the network device may indicate the transmit power indication information of the beam by sending a MAC CE, and indicate the indication information of the effective time of the transmit power indication information of the beam by sending a DCI. In another example, the network device may indicate the indication information of the effective time of the transmit power indication information of the beam by sending a MAC CE, and indicate the transmit power indication information of the beam by sending a DCI.
[0158] For example, taking the case where the relevant information of a beam includes the transmit power indication information of the beam and the indication information of the effective time, and the two types of information jointly indicated are RRC signaling and DCI, in one example, the network device may indicate the transmit power indication information of the beam by sending RRC signaling, and indicate the indication information of the effective time of the transmit power indication information of the beam by sending DCI. In another example, the network device may indicate the indication information of the effective time of the transmit power indication information of the beam by sending RRC signaling, and indicate the transmit power indication information of the beam by sending DCI.
[0159] It should be noted that the principle of the network device sending three or more types of information to jointly indicate the relevant information of the beam is similar to the above-mentioned principle of sending two types of information to jointly indicate the relevant information of the beam, and the embodiments of the present application will not be expanded.
[0160] In the above S301, the network device may send the first information to the terminal device so that the terminal device performs beam measurement according to the first information. The following describes how the terminal device performs beam measurement according to the first information.
[0161] S302. The terminal device generates a beam measurement result based on the first information.
[0162] In some embodiments, the terminal device may measure the beam indicated in the first information based on the first information and at least one measurement mode for the measurement beam, and generate a beam measurement result. The at least one measurement mode for the measurement beam may be protocol-specified or network-configured. For details on the network-configured measurement mode, see the embodiments below.
[0163] In some embodiments, the measurement mode may also be described as a filtering mode.
[0164] The beam measurement mode includes at least one of the following: a first measurement mode, a second measurement mode, and a third measurement mode. The first measurement mode, the second measurement mode, and the third measurement mode are described below.
[0165] (1) First measurement mode
[0166] In some embodiments, the terminal device may measure the beam indicated in the first information based on the first information and the first measurement mode to generate a measurement result of the beam.
[0167] The measurement principle of the first measurement mode is described in detail below. For ease of understanding, the following example uses the relevant information indicating a beam in the first information (including the transmission power indication information of the beam) as an example for explanation.
[0168] FIG5 exemplarily shows a flowchart of a first measurement mode provided in an embodiment of the present application. Referring to FIG5 , the measurement process of the first measurement mode may include:
[0169] S501. The terminal device obtains the measurement results of the beam in at least one time period and a first weight coefficient of the measurement results of the beam in at least one time period.
[0170] S502. The terminal device performs weighted processing on the measurement result of the beam in at least one time period according to the first weight coefficient of the measurement result of the beam in at least one time period to obtain the measurement result of the beam.
[0171] Among them, the first weight coefficient of the measurement result of the beam in the first time period is negatively correlated with the transmission power value of the beam in the first time period, and the first time period is any time period in at least one time period, for example, the first time period is the i-th time period in the following text.
[0172] In some embodiments, the terminal device may determine a first weight coefficient of the measurement result of the beam in the effective period (i.e., the effective measurement period) based on the transmit power value of the beam indicated in the first information and the preset transmit power value. For details, see Formula 2. i =A / P i Formula 2
[0173] Where, β i The first weight coefficient represents the measurement result of the beam in the i-th time period (a certain effective time period). A is a reference value, that is, a preset transmit power value. A can be configured by the network, agreed by the protocol, or determined by the terminal according to the power level information of the network device. P i Indicates the transmit power value of the beam in the i-th time period.
[0174] Formula 2 shows that the first weight coefficient of the measurement result of the beam in time period i is negatively correlated with the transmit power value of the beam in time period i. The greater the transmit power value of the beam in time period i, the smaller the first weight coefficient of the measurement result; the smaller the transmit power value of the beam in time period i, the larger the first weight coefficient of the measurement result.
[0175] Exemplarily, Table 1 shows a mapping relationship table between measurement results of the beam in N time periods and the first weight coefficient, where N is a positive integer.
[0176] Table 1
[0177] In one example, the effective period of the transmit power value of the beam indicated in the first information is the Nth period shown in Table 1. The terminal device can obtain the final measurement result of the beam in the Nth period in the following manner: the terminal device obtains the measurement result of the beam in the Nth period (ie, M N ), and the first weight coefficient of the measurement result of the beam in the Nth time period (ie, β N ), the final measurement result of the beam in the Nth time period (denoted as F N ). F N =β N ·M N Formula 3
[0178] In this example, the terminal device uses the actual measurement result (such as the Mth time period above) of the beam in the target time period (such as the Nth time period above) to calculate the actual measurement result (such as the Mth time period above) of the beam in the target time period (such as the Nth time period above) N ) and the first weight coefficient corresponding to the target period (such as the above β N ) to balance the measurement results of the beam in the target time period. This can eliminate the impact of the beam transmission power fluctuation (too large or too small) corresponding to the target time period on the reported beam measurement results to a certain extent, and improve the accuracy of the beam measurement results. It enables the network equipment to more accurately obtain the size of the propagation path loss, the beam direction alignment, etc. according to the beam measurement results reported by the terminal equipment.
[0179] Based on this example, it should be understood that if the beam transmit power P in a certain period of time i When it is larger, the corresponding first weight coefficient β can be known based on formula 2 i Small, by multiplying the two, the effect of balancing the beam measurement results in this period can be achieved. Similarly, if the beam transmit power P in a certain period i When it is small, the corresponding first weight coefficient β can be known based on formula 2 i The beam measurement results of this period can be balanced by multiplying the two.
[0180] In another example, the effective period of the transmit power value of the beam indicated in the first information is the Nth period shown in Table 1, and the terminal device can obtain the final measurement result of the beam in the Nth period in the following manner: the terminal device obtains the measurement result of the beam in the Nth period (ie, M N ), the final measurement result of the beam in the N-1th time period (denoted as F N-1 ), the first weight coefficient of the measurement result of the beam in the Nth time period (i.e., β N ), the first weight coefficient of the measurement result of the beam in the N-1th time period (i.e., β N-1 ) and the filter coefficient of the terminal device (denoted as α, α can be configured by the network). The terminal device determines the final measurement result of the beam in the Nth time period (denoted as F N ). F N =(1-α)·F N-1 +α·β N ·M N Formula 4
[0181] Where, if N is 1, F0 can be set to β1·M1.
[0182] In this example, when the terminal device measures the measurement result of the beam in the target time period (such as the Nth time period mentioned above), it considers the measurement result of the beam in the adjacent time period before the target time period (or multiple consecutive time periods before the target time period), and obtains the weighted measurement result by weighting the measurement results of the beam in multiple time periods. The weighted measurement result is used as the final measurement result of the beam in the target time period. It is worth noting that the weight coefficient β is added on the basis of the weight coefficients 1-α and α. N By balancing the measurement results of the beam in the target time period, the influence of the fluctuation of the beam transmission power (too large or too small) corresponding to the target time period on the reported beam measurement results can be eliminated to a certain extent, and the accuracy of the beam measurement results can be improved, so that the network equipment can more accurately obtain the size of the propagation path loss, the beam direction alignment, etc. according to the beam measurement results reported by the terminal equipment.
[0183] (2) Second measurement mode
[0184] In some embodiments, the terminal device may measure the beam indicated in the first information based on the first information and the second measurement mode to generate a measurement result of the beam.
[0185] The measurement principle of the second measurement mode is described in detail below. For ease of understanding, the following example uses the relevant information indicating a beam in the first information (including the transmission power indication information of the beam) as an example for explanation.
[0186] FIG6 exemplarily shows a flow chart of the second measurement mode provided in an embodiment of the present application. Referring to FIG6 , the measurement process of the second measurement mode may include:
[0187] S601. The terminal device obtains a measurement result of a beam in at least one time period and a second weight coefficient of the measurement result of the beam in at least one time period.
[0188] S602. The terminal device performs weighted processing on the measurement result of the beam in at least one time period according to the second weight coefficient of the measurement result of the beam in at least one time period to obtain the measurement result of the beam.
[0189] The second weight coefficient of the measurement result of the beam in the first time period is positively correlated with the transmit power value of the beam in the first time period, and the first time period is any time period of at least one time period.
[0190] In some embodiments, the terminal device may determine the second weight coefficient of the measurement result of the beam in the effective period according to the transmit power value of the beam in the effective period indicated in the first information and the preset transmit power value. For details, see Formula 5. i =P i / A Formula 5
[0191] Where, γ i The second weight coefficient represents the measurement result of the beam in the i-th time period (a certain effective time period). A is a reference value, that is, a preset transmit power value. A can be configured by the network, agreed by the protocol, or determined by the terminal according to the power level information of the network device. P i Indicates the transmit power value of the beam in the i-th time period.
[0192] Formula 5 shows that the second weight coefficient of the measurement result of the beam in time period i is positively correlated with the transmit power value of the beam in time period i. The greater the transmit power value of the beam in time period i, the greater the second weight coefficient of the measurement result; the smaller the transmit power value of the beam in time period i, the smaller the second weight coefficient of the measurement result.
[0193] Exemplarily, Table 2 shows a mapping relationship table between measurement results of the beam in N time periods and the second weight coefficient, where N is a positive integer.
[0194] Table 2
[0195] In one example, the effective period of the transmit power value of the beam indicated in the first information is the Nth period shown in Table 2. The terminal device can obtain the final measurement result of the beam in the Nth period in the following manner: the terminal device obtains the measurement result of the beam in the Nth period (ie, M N ), and the second weight coefficient of the measurement result of the beam in the Nth time period (i.e., γ N ), the final measurement result of the beam in the Nth time period (denoted as F N ). F N =γ N ·M N Formula 6
[0196] In this example, the terminal device uses the actual measurement result (such as the Mth time period above) of the beam in the target time period (such as the Nth time period above) to calculate the actual measurement result (such as the Mth time period above) of the beam in the target time period (such as the Nth time period above) N ) and the second weight coefficient corresponding to the target period (such as the above-mentioned γ N ) to obtain the final measurement result of the beam in the target time period, so that the network equipment can more accurately obtain the signal quality actually received by the terminal device based on the beam measurement result reported by the terminal device, facilitating accurate service scheduling.
[0197] Based on this example, it should be understood that if the beam transmit power P in a certain period of time i When it is larger, the corresponding second weight coefficient γ can be known based on formula 5 i The beam measurement result of this period can be more accurately indicated by multiplying the two. Similarly, if the beam transmit power P in a certain period i When it is smaller, the corresponding second weight coefficient β can be known based on formula 5 i The multiplication of the two can more accurately indicate the beam measurement result of the period.
[0198] In another example, the effective period of the transmit power value of the beam indicated in the first information is the Nth period shown in Table 2, and the terminal device can obtain the final measurement result of the beam in the Nth period in the following manner: the terminal device obtains the measurement result of the beam in the Nth period (ie, M N ), the final measurement result of the beam in the N-1th time period (denoted as F N-1 ), the second weight coefficient of the measurement result of the beam in the Nth time period (i.e., γ N ), the second weight coefficient of the measurement result of the beam in the N-1th time period (i.e., γ N-1) and the filter coefficient of the terminal device (denoted as α, which can be configured by the network). The terminal device determines the final measurement result of the beam in the Nth time period (denoted as F N ). F N =(1-α)·F N-1 +α·γ N ·M N Formula 7
[0199] Where, if N is 1, F0 can be set to γ1·M1.
[0200] In this example, when the terminal device measures the measurement result of the beam in the target time period (such as the Nth time period mentioned above), it considers the measurement result of the beam in the adjacent time period before the target time period (or multiple consecutive time periods before the target time period), and obtains the weighted measurement result by weighting the measurement results of the beam in multiple time periods. The weighted measurement result is used as the final measurement result of the beam in the target time period. It is worth noting that the weight coefficient γ is added on the basis of the weight coefficients 1-α and α. N , which enables network equipment to more accurately obtain the actual signal quality received by the terminal device based on the beam measurement results reported by the terminal device, facilitating accurate service scheduling.
[0201] (3) The third measurement mode
[0202] In some embodiments, the terminal device may measure the beam indicated in the first information based on the first information and the third measurement mode to generate a measurement result of the beam.
[0203] The measurement principle of the third measurement mode is described in detail below. For ease of understanding, the following example uses the relevant information indicating a beam in the first information (including the transmission power indication information of the beam) as an example for explanation.
[0204] FIG7 exemplarily shows a flowchart of a third measurement mode provided in an embodiment of the present application. Referring to FIG7 , the measurement process of the third measurement mode may include:
[0205] S701. The terminal device obtains measurement results of the beam in multiple time periods.
[0206] The terminal device receives first information sent by the network device, wherein the first information indicates transmit power indication information of the beam, and the terminal device can obtain measurement results of the beam in multiple time periods. The multiple time periods can include a current time period and at least one time period before the current time period, and the time period can refer to the effective time period of the beam.
[0207] For example, referring to Table 1 or Table 2, the terminal device obtains the measurement results of the beam in N time periods, which are M1 to M2. N , where M N It can be regarded as the measurement result of the beam in the current period, M1 to M N-1 It can be regarded as the measurement result of the beam in the N-1 consecutive time periods before the current time period.
[0208] S702. The terminal device clusters and groups the measurement results of the beams in multiple time periods.
[0209] In some embodiments, the terminal device may cluster and group the measurement results of the beams in multiple time periods by the following steps:
[0210] S7021. The terminal device obtains a third weight coefficient of the measurement results of the beam in multiple time periods.
[0211] In one example, the third weight coefficient may be the first weight coefficient, i.e., the first weight coefficient used by the terminal device to obtain measurement results of the beam in multiple time periods. Taking a certain time period among the multiple time periods, such as the first time period, as an example, the terminal device may determine the first weight coefficient of the measurement result of the beam in the first time period based on the transmit power value of the beam in the first time period indicated in the first information and the preset transmit power value. Exemplarily, the terminal device may use the ratio of the preset transmit power value to the transmit power value of the beam in the first time period as the first weight coefficient of the measurement result of the beam in the first time period, as shown in Formula 2.
[0212] In this example, the third weight coefficient of the measurement result of the beam in the first time period is negatively correlated with the transmit power value of the beam in the first time period, where the first time period is any time period from among the multiple time periods. For an exemplary correspondence between the third weight coefficient of the measurement result of the beam in multiple time periods and the transmit power value of the beam in the multiple time periods, see Table 1.
[0213] In one example, the third weight coefficient may be the second weight coefficient, i.e., the second weight coefficient used by the terminal device to obtain measurement results of the beam in multiple time periods. Taking a certain time period of the multiple time periods, such as the first time period, as an example, the terminal device may determine the second weight coefficient of the measurement result of the beam in the first time period based on the transmit power value of the beam in the first time period indicated in the first information and the preset transmit power value. Exemplarily, the terminal device may use the ratio of the transmit power value of the beam in the first time period to the preset transmit power value as the second weight coefficient of the measurement result of the beam in the first time period, as shown in Formula 5.
[0214] In this example, the third weight coefficient of the measurement result of the beam in the first time period is positively correlated with the transmit power value of the beam in the first time period, where the first time period is any time period from among the multiple time periods. For example, the correspondence between the third weight coefficients of the measurement results of the beam in multiple time periods and the transmit power values of the beam in the multiple time periods can be seen in Table 2.
[0215] S7022. The terminal device clusters the measurement results of beams in multiple time periods whose third weight coefficients are equal, or whose absolute values of the differences between the third weight coefficients are less than a threshold, into the same group.
[0216] In one example, the third weight coefficient may be the first weight coefficient. Referring to Table 1, if the third weight coefficient of the measurement result of the beam obtained by the terminal device in N time periods includes β1 to β N , the terminal device can make the third weight coefficient of the beam in the measurement results of N time periods equal to |β i -β j |=0, or the absolute value of the difference between the third weight coefficients is less than the threshold value |β i -β j |<b are clustered into the same group. Exemplarily, based on the clustering method of this example, the measurement results of the N beams in Table 1 can be divided into 3 groups, for example, the first group is {M1}, the second group is {M2, M N-1}, the third group is {M3,…,M N-2 ,M N}, the clustered group may include the measurement results of the beam in one time period, such as group 1, or may include the measurement results of the beam in multiple time periods, such as group 2 and group 3.
[0217] In one example, the third weight coefficient may be the second weight coefficient. Referring to Table 2, if the third weight coefficient of the measurement result of the beam obtained by the terminal device in N time periods includes γ1 to γ N , the terminal device can make the third weight coefficient of the beam in the measurement results of N time periods equal to |γ i -γ j |=0, or the absolute value of the difference between the third weight coefficients is less than the threshold value |γ i -γ j |<b are clustered into the same group. Exemplarily, based on the clustering method of this example, the measurement results of the N beams in Table 2 can be divided into 2 groups, for example, the first group is {M1, M2}, the second group is {M3}, and the third group is {M4, ..., M5}. N The clustered groups include the measurement results of the beam in one time period, such as group 2, and also include the measurement results of the beam in multiple time periods, such as group 1 and group 3.
[0218] Through the above clustering method, the terminal device can divide the measurement results of the beam in multiple time periods into multiple groups, and each group can include the measurement results of the beam in one or more time periods.
[0219] In another embodiment, the terminal device may cluster and group the measurement results of the beam in multiple time periods according to the transmit power values of the beam. Exemplarily, the first information may indicate the transmit power values of a certain beam in multiple consecutive time periods, and the transmit power values of the beam in different time periods may be different. The terminal device obtains the measurement results of the beam in multiple time periods, and may group the measurement results of the beam in multiple time periods according to the transmit power values of the beam in different time periods. For example, the transmit power values of a certain beam in time periods 1 to 5 are P1, P2, P2, P1, P1 respectively. The terminal device groups the measurement results of the beam in time periods 1, 4, and 5 into one group, and groups the measurement results of the beam in time periods 2 and 3 into one group.
[0220] S703. The terminal device obtains the overall measurement results of each group of beams.
[0221] For ease of understanding, the following takes the first group after clustering as an example to illustrate the overall measurement results of the beams of the first group obtained by the terminal device. The first group is any group among the multiple groups after clustering.
[0222] In some embodiments, the terminal device performs weighted processing on the measurement results of the first group of beams in at least one time period based on the third weight coefficient of the measurement results of the first group of beams in at least one time period to obtain an overall measurement result of the first group of beams.
[0223] In an example of this embodiment, if the third weight coefficient is the first weight coefficient, the first group includes the measurement results of the beam in a time period, and the terminal device performs weighted processing on the measurement results of the beam of the first group in a time period according to the first weight coefficient of the measurement results of the beam of the first group in a time period to obtain the overall measurement results of the beam of the first group.
[0224] Exemplarily, the terminal device may use the product of the measurement results of the first group of beams in a time period and the first weight coefficient of the measurement results in the time period as the overall measurement results of the first group of beams. For example, in the first example of step 7022, the first group after clustering is {M1}, then the overall measurement results of the beams of this group can be expressed as: β1·M1.
[0225] In an example of this embodiment, if the third weight coefficient is the first weight coefficient, the first group includes measurement results of beams in multiple time periods, and the terminal device performs weighted processing on the measurement results of the beams of the first group in multiple time periods according to the first weight coefficient of the measurement results of the beams of the first group in multiple time periods to obtain the overall measurement results of the beams of the first group.
[0226] For example, the terminal device may perform weighted summation of the measurement results of the first group of beams in multiple time periods with the first weight coefficient of the measurement results of the multiple time periods to obtain the overall measurement results of the first group of beams. For example, in the first example of step 7022, the clustered second group is {M2, M N-1}, the overall measurement result of the beam of this group can be expressed as: β2·M2+β N-1 ·M N-1 .
[0227] In an example of this embodiment, if the third weight coefficient is the second weight coefficient, the first group includes the measurement results of the beam in a time period, and the terminal device performs weighted processing on the measurement results of the beam of the first group in a time period according to the second weight coefficient of the measurement results of the beam of the first group in a time period to obtain the overall measurement results of the beam of the first group.
[0228] Exemplarily, the terminal device may use the product of the measurement result of the first group's beams in a time period and the second weight coefficient of the measurement result in the time period as the overall measurement result of the first group's beams. For example, in the second example of step 7022, if the clustered second group is {M3}, the overall measurement result of the beams of this group can be expressed as: γ3·M3.
[0229] In an example of this embodiment, if the third weight coefficient is the second weight coefficient, the first group includes measurement results of beams in multiple time periods, and the terminal device performs weighted processing on the measurement results of the beams of the first group in multiple time periods according to the second weight coefficient of the measurement results of the beams of the first group in multiple time periods to obtain the overall measurement results of the beams of the first group.
[0230] Exemplarily, the terminal device may perform a weighted summation of the measurement results of the first group's beams in multiple time periods and the second weight coefficient of the measurement results in the multiple time periods to obtain an overall measurement result of the first group's beams. For example, in the second example of step 7022, if the clustered first group is {M1, M2}, the overall measurement result of the beams in this group can be expressed as: γ1·M1+γ2·M2.
[0231] In some embodiments, the terminal device uses an average value of the measurement results of the beams of the first group in at least one time period as the overall measurement result of the beams of the first group.
[0232] In one example of this embodiment, if the first group includes measurement results of beams in multiple time periods, the terminal device uses the average value of the measurement results of the beams in the multiple time periods as the overall measurement result of the beams in the first group. For example, in the first example of step 7022, the clustered second group is {M2, M N-1}, the overall measurement result of the beam of this group can be expressed as: (M2+M N-1 ) / 2.
[0233] It should be understood that if the first group includes measurement results of the beam in a time period, the terminal device may use the measurement results of the beam in the time period as the overall measurement results of the beam in the first group.
[0234] S704. The terminal device uses the overall measurement result of at least one group of beams as the measurement result of the beams.
[0235] In some embodiments, after obtaining the overall measurement results of the clustered multiple groups of beams, the terminal device selects one group from the multiple groups of overall measurement results of the beams, and uses the overall measurement result of the beams of the group as the measurement result of the beam. The overall measurement result of the beams of the group may be the maximum value, the minimum value, or any value among the overall measurement results of the beams of the multiple groups. That is, the measurement result of the beam may be the maximum value, the minimum value, or any value among the overall measurement results of the beams of the multiple groups.
[0236] In some embodiments, after the terminal device obtains the overall measurement results of the clustered multiple groups of beams, it selects two groups from the overall measurement results of the multiple groups of beams and uses the overall measurement results of the two groups of beams as the measurement results of the beams.
[0237] For example, the measurement results for a beam include the maximum value and any value other than the maximum value of the overall measurement results for the beams of the plurality of groups. For another example, the measurement results for a beam include the minimum value and any value other than the minimum value of the overall measurement results for the beams of the plurality of groups. For another example, the measurement results for a beam include the maximum value and the minimum value of the overall measurement results for the beams of the plurality of groups.
[0238] In some embodiments, after obtaining the overall measurement results of the clustered multiple groups of beams, the terminal device uses the overall measurement results of the multiple groups of beams as the beam measurement result. That is, the beam measurement result includes the overall measurement results of the multiple groups of beams. For example, if there are three groups of overall measurement results for the clustered beams, the overall measurement results of all three groups of beams are reported to the network.
[0239] In the third measurement mode mentioned above, the terminal device can group and analyze the measurement results of the beam in multiple time periods to obtain the overall measurement results of the beam in different groups, and can report the overall measurement results of one or more groups of beams to the network device so that the network device can more accurately obtain the fluctuations in the wireless signal quality.
[0240] In summary, the measurement mode agreed upon by the protocol may be at least one of the first measurement mode, the second measurement mode, or the third measurement mode. Taking a certain beam as an example, the measurement result of the beam reported by the terminal device to the network device may include at least one of the following:
[0241] The terminal device measures the beam according to the first measurement mode and determines the measurement result of the beam (see the above part (1) for details);
[0242] The measurement result of the beam determined by the terminal device by measuring the beam according to the second measurement mode (see the above part (2) for details);
[0243] The terminal device measures the beam according to the third measurement mode and determines the measurement result of the beam (see the above part (3) for details).
[0244] In an embodiment of the present application, the measurement result of the beam includes at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), reference signal strength indicator (RSSI), and signal to interference plus noise ratio (SINR).
[0245] S303. The terminal device sends second information to the network device, where the second information is used to indicate the measurement result of the beam.
[0246] After generating measurement results for one or more beams, the terminal device sends second information to the network device, including the measurement results. Upon receiving the second information, the network device may adjust the beams and their transmit power based on the measurement results of the one or more beams in the second information to optimize system communication quality.
[0247] In some embodiments, the second information may be uplink control information (UCI), or MAC CE, or RRC signaling.
[0248] In the communication method shown in the embodiment of the present application, the terminal device receives first information, and the first information is used to indicate relevant information of one or more beams. The terminal device can perform the above-mentioned measurement on the one or more beams based on the relevant information of the one or more beams indicated by the first information and the measurement mode agreed upon by the protocol (which can be at least one of the first measurement mode, the second measurement mode or the third measurement mode) to generate measurement results of one or more beams. The terminal device reports the measurement results of the one or more beams to the network device, so that the network device adjusts the beam and its transmission power based on the report to achieve the purpose of optimizing the system communication quality.
