Description

[Technical Field]

[0001] The present disclosure relates to the field of wireless communication technology, but is not limited to it, and more particularly to information transmission methods and apparatus, communication devices and storage media. [Background technology]

[0002] In the evolution of 5th generation mobile communications, beamforming technology is used in the FR2 millimeter wave frequency band. When receiving radio signals, User Equipment (UE) no longer uses omnidirectional antennas as in the FR1 low frequency band. Instead, it additionally introduces receive beamforming management to receive using the best receive beam, achieving larger uplink coverage and better transmission speeds. At the same time, the introduction of the beam concept also introduces a spatial dimension into UE transmission, meaning that physical resources at the same time and frequency can be further multiplexed by different beams.

[0061] Referring to Figure 1, a structural schematic diagram of a wireless communication system provided by an embodiment of the present disclosure is shown. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system includes several UEs 11 and several network devices 12.

[0062] The wireless communication system may be a 4th generation mobile communication (4G) system, also called a Long Term Evolution (LTE) system, or a 5G system, also called a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a next-generation system of a 5G system. Here, an access network in a 5G system may be called a New Generation-Radio Access Network (NG-RAN). Alternatively, the wireless communication system may be a Machine Type Communication (MTC) system.

[0063] The UE 11 may refer to a device that provides voice and / or data connectivity to a user. The UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). The UE 11 may be an Internet of Things UE, such as a sensor device, a mobile phone (also called a "cellular" phone), or a computer with an Internet of Things UE, and may be, for example, a fixed, portable, pocket, handheld, computer-integrated, or vehicle-mounted device. For example, the UE 11 may be a station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, the UE 11 may be an unmanned aerial vehicle (UAV) device. Alternatively, the UE 11 may be an in-vehicle device, such as a driving computer with a wireless communication function, or a wireless communication device connected to an external driving computer, or may be a roadside device, such as a street lamp, a traffic light, or other roadside device with a wireless communication function.

[0064] The network device 12 may include an access network device. Optionally, the network device 12 may further include a core network device. The access network device may be an evolved access device (eNB) adopted in a 4G system. Alternatively, the access network device may be an access device (gNB) using a centralized-distributed architecture in a 5G system. When the access network device uses a centralized-distributed architecture, it typically includes a centralized unit (CU) and at least two distributed units (DUs). The centralized unit is configured with protocol stacks for a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer, and the distributed units are configured with a physical (PHY) layer protocol stack. The embodiments of the present disclosure do not limit the specific implementation form of the access network device.

[0065] A wireless connection can be established between the network device 12 and the UE 11 via a wireless air interface. In different embodiments, the wireless air interface can be a wireless air interface based on a fourth generation mobile communication network technology (4G) standard, or the wireless air interface can be a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, for example, the wireless air interface can be a new radio, or the wireless air interface can be a wireless air interface based on a 5G next-generation communication network technology standard.

[0066] As shown in Figure 2, the UE uses a receive beam scanning method to achieve better reception angle coverage. Currently, the FR2 frequency band UE antenna uses a method in which eight receive beams cover a 120° range, that is, the UE generates eight beams through beamforming, each pointing to a beam direction, achieving 120° beam coverage. As shown in Figure 2, r1-r8 represent the eight receive beams generated by UE beamforming, and each receive beam corresponds to a receive beam direction.

[0067] 3GPP Standard Release 16 (Rel-16) introduces the UE capability indicated by simultaneousReceptionDiffTypeD-r16, which indicates whether the UE can simultaneously receive two different QCL-D-related reference signals. The UE can configure two antenna panels in FR2 and simultaneously receive signals via antenna arrays at different positions on the two antenna panels, supporting the terminal's ability to achieve simultaneousReceptionDiffTypeD-r16 (i.e., the ability to simultaneously receive two different QCL-D-related reference signals). As shown in Figure 2, each antenna panel basically uses a technical solution in which eight receiving beams cover 120°. Since simultaneousReceptionDiffTypeD-r16 only indicates whether the UE can receive signals in different directions, the indication of the UE's actual capabilities is unclear, leading to unclear indication of the corresponding UE receiving capability, which prevents the base station from accurately determining the terminal's actual multiple receiving capabilities. In fact, the two antenna panels of the terminal have three different situations in which the beams generated by the two antenna panels do not overlap, partially overlap, and completely overlap, based on different technical solutions implemented.

[0068] The current UE reporting cannot realize the actual antenna beam overlap situation, and the base station cannot clearly determine the UE's actual receiving capability. The base station does not sufficiently consider resource scheduling such as measuring the UE reference signal, and the base station may set too many measurement times, which may result in a waste of time domain resources.

[0069] Therefore, how to improve the accuracy of UE resource configuration based on beamforming by a base station and improve resource utilization efficiency is an issue that needs to be resolved urgently.

[0070] As shown in FIG. 3, an embodiment of the present disclosure provides an information transmission method, which is performed by a user equipment (UE), and includes the following steps: Step 301: Send capability information of the UE to a network device, and the capability information is used for the network device to determine the number n of rounds of reference signal measurements that the UE will perform in I receive beam directions, where one round of reference signal measurements includes measurements of the reference signals performed by J antennas in X receive beam directions, and the J antennas cover the I receive beam directions, where J is a positive integer greater than 2, X is a positive integer less than or equal to J, and I is a positive integer greater than J.

[0071] In one embodiment, the UE includes J antennas.

[0072] For example, J=2, ie, the UE includes two antennas.

[0073] In one embodiment, the UE's J antennas cover a total of I receive beam directions.

[0074] For example, a UE includes two antennas, and the receive beam of each antenna covers eight receive beam directions, and the receive beam of the two antennas covers 16 receive beam directions.

[0075] For example, if a UE includes two antennas, and the receiving beam of each antenna covers eight receiving beam directions, and the receiving beam directions of one receiving beam of the two antennas overlap, the receiving beams of the two antennas cover 15 receiving beam directions. This is an analogy and will not be described in detail.

[0076] In one embodiment, J antennas of the UE can simultaneously measure reference signals in X receive beam directions.

[0077] For example, if a UE includes two antennas, the two antennas can simultaneously measure the reference signal in the same receive beam direction, and X = 1. The two antennas can simultaneously measure the reference signal in different receive beam directions, and X = 2.

[0078] In one example, the antenna includes an antenna panel, where an antenna panel includes at least one antenna array, where each antenna array includes at least two antenna elements.

[0079] That is, the antenna of the UE may be an antenna panel. The antenna panel may be configured with one or more antenna arrays. Different beamforming may be realized through the antenna array. In one possible implementation, one antenna may form receive beams in different directions through a beamforming scheme. The UE may receive a reference signal transmitted by a network device through multiple receive beams obtained through beamforming.

[0080] Illustratively, one receive beam may correspond to one receive beam direction. In one possible implementation, the network device includes, but is not limited to, at least one of an access network device (e.g., a base station) and a core network device.

[0081] The core network device may transmit a reference signal to the UE via the access network device.

[0082] In one possible implementation, the reference signal includes, but is not limited to, an SSB, and the measurement of the reference signal may be an L1-RSRP measurement on the SSB.

[0083] In one round of signal measurement, J antennas can each measure a reference signal. In one round of signal measurement for J antennas, the receiving beam directions can be the same or different. Therefore, in one round of signal measurement, J antennas can measure X receiving beam directions, where X is greater than or equal to 1 and less than or equal to J. For example, if the receiving beam directions are all the same in one round of signal measurement for J antennas, X=1; if the receiving beam directions are different in one round of signal measurement for J antennas, X=J.

[0084] A UE may have J antennas, each corresponding to K receive beam directions. The receive beam directions of two antennas may overlap, so the number I of receive beam directions through which the UE can actually receive the reference signal is J*K or less. It should be understood that if the receive beam directions of two UE antennas (e.g., antenna A and antenna B) overlap, for example, if the receive beam direction of one receive beam of antenna A is the same as the receive beam direction of one receive beam of antenna B, the measurement result of the reference signal in the receive beam direction can be determined simply by measuring in the receive beam direction of any one of antennas A or B. Here, the receive beam directions overlap, i.e., the receive beams overlap. The receive beam directions may overlap when the difference between the receive beam directions is less than a predetermined threshold.

[0085] In some embodiments, a UE may have J (e.g., J=2) antennas, each corresponding to K (e.g., K=8) receive beam directions. Because there may be situations where the receive beam directions of two antennas overlap, the number I of receive beam directions in which the UE can actually receive reference signals is J*K or less, e.g., I=14.

[0086] Therefore, for the UE to complete signal measurement in I receive beam directions, it may need to perform one or multiple rounds of signal measurement, where each round measures X receive beam directions. Therefore, X is less than or equal to I. For example, as shown in FIG. 4, the UE includes two antennas (antenna 1 and antenna 2, where antenna 1 corresponds to beams r1 to r8 and antenna 2 corresponds to beams R1 to R8), and each antenna corresponds to eight receive beam directions. There may be overlap between two receive beam directions for the two antennas (the r2 receive beam of antenna 1 overlaps with the R8 receive beam direction of antenna 2, and the r1 receive beam direction of antenna 1 overlaps with the R7 receive beam direction of antenna 2). Therefore, the number I of receive beam directions in which the UE can actually receive the reference signal is 14, which is less than the total number of beams (16) for the two antennas.

[0087] In one possible implementation, the UE has the capability to simultaneously receive multiple different QCL-D related reference signals.

[0088] In one possible implementation, the UE does not have the capability to simultaneously receive multiple different QCL-D related reference signals.

[0089] Here, the reference signals of different QCL-D relationships may include reference signals of different receive beam directions.

[0090] In one possible implementation, one round of measuring the reference signal includes multiple simultaneous measurements of the reference signal, where one measurement of the reference signal can correspond to one antenna.

[0091] In one embodiment, the J antennas of the UE each support simultaneous measurements of a reference signal in the same or different receive beam directions.

[0092] In one possible implementation, one round of measurements of the reference signal includes measurements of the reference signal made simultaneously by J antennas in X directions of the receive beams.

[0093] 4, the UE can use two antennas to simultaneously measure reference signals in two receive beam directions. For example, the UE can simultaneously receive a reference signal in the r8 receive beam direction and a reference signal in the R1 receive beam direction using antenna 1 and antenna 2. Alternatively, the UE can use antenna 1 to receive a reference signal in the r2 receive beam direction and antenna 2 to simultaneously receive a reference signal in the R7 receive beam direction.

[0094] In some embodiments, factors that influence the number n of rounds of reference signal measurements that the UE makes in the I receive beam directions may include, but are not limited to, at least one of the following: Whether there are overlapping receive beams among the J antennas, whether there is overlap in the receive beam directions of the overlapping receive beams, the number of overlapping receive beams among the J antennas, and whether the UE supports the ability to simultaneously receive reference signals with different QCL-D relationships.

[0095] Here, the receive beam overlap may be an overlap of the receive beam directions. Whether the receive beam directions overlap can be determined based on the difference between the receive beam directions. For example, if the difference between the receive beam directions of two receive beams is smaller than a threshold, the two receive beam directions overlap; otherwise, the two receive beam directions do not overlap.

[0096] In one possible implementation, when J is greater than 3, the number of overlapping receive beams present among the J antennas may include at least one of the number of overlapping receive beams present between two antennas, the number of overlapping receive beams present between two or more antennas.

[0097] In one possible implementation, the overlap of receive beam directions may include beam coverage range overlap.

[0098] In one possible implementation, if the receive beams have the same broadcast angle, then if the receive beam directions overlap, the beam coverage ranges will also overlap.

[0099] The UE can determine the number of rounds n of measurements of the reference signal that the UE will perform in the I receive beam directions based on the above factors.

[0100] For example, as shown in Figure 4, the directions of the r2 receive beam of antenna 1 and the R8 receive beam of antenna 2 overlap, and the r1 receive beam of antenna 1 and the R7 receive beam of antenna 2 overlap, and the UE has the ability to simultaneously receive reference signals with two different QCL-D relationships. Therefore, in one round of reference signal measurement, the UE can measure reference signals in two receive beam directions. The 14 receive beam directions shown in Figure 4 can be completed by the UE through seven rounds of reference signal measurement.

[0101] The UE may send capability information to the network device to determine the number n of rounds of reference signal measurements that the network device will make.

[0102] In one possible implementation, the capability information indirectly determines the number n of rounds of reference signal measurements that the network device will perform, for example, the capability information is used to indicate the above-mentioned decision factor, and the network device calculates the number n of rounds of reference signal measurements that the network device will perform based on the decision factor.

[0103] In one embodiment, the capability information includes a receive beam coverage factor, which is used to indicate the number of rounds n, where the coverage factor is related to the number of receive beam directions that overlap with each other among the J antennas.

[0104] Here, the cover coefficient represents the number of rounds of signal measurement that the UE performs to complete measurement of the reference signals in the I receiving beam directions. Here, the name of the cover coefficient is not limited.

[0105] The UE can directly indicate the round number n to the network device through the capability information, thereby reducing the amount of data to be transmitted and the signaling load, and also reducing the load caused by the network device calculating the round number n according to the decision factor.

[0106] In one possible implementation, the cover factor can be "Beamoverlapscalingfactor".

[0107] The following describes the coverage factor using an example where a UE has two antennas, each corresponding to eight receiving directions. The UE can send the BeamOverlapScalingFactor to the network device. For example, the default BeamOverlapScalingFactor=8 indicates that the terminal must complete eight rounds of SSB measurement to complete SSB-based L1-RSRP measurement (one round of SSB measurement is performed simultaneously on two antennas). This means that the UE's two antenna panels do not receive beam coverage (i.e., a total of 16 beam directions need to be measured). For example, the beam overlap scaling factor is 4. The eight beams of the terminal's two antennas completely overlap (i.e., a total of eight beam directions need to be measured), and the UE can complete SSB-based L1-RSRP measurements for all receiving beams in four rounds of SSB measurements (one round of SSB measurements means that two antennas can simultaneously perform SSB measurements for different receiving beam directions).

[0108] In this way, the capability information allows the network device to determine the number of measurement rounds required for the UE to measure the reference signal, which can reduce the deviation in determining the number of measurement rounds for the reference signal measurement caused by the network device not determining the UE capability, and further improve the accuracy of the network device's resource configuration.

[0109] In one embodiment, the number of rounds n is determined based on the number of receive beam directions associated with each of the antennas and the number of overlapping receive beam directions that the J antennas have.

[0110] In one possible implementation, the number of rounds n is directly correlated with the number of receive beam directions associated with each antenna.

[0111] The more receive beam directions associated with each antenna, the more rounds n of measurements that need to be taken.

[0112] In one possible implementation, the number of rounds n is negatively correlated with the determination of the number of overlapping receive beam directions that the J antennas have.

[0113] The more overlapping receive beam directions the J antennas have, the fewer the number of rounds n that need to be measured.

[0114] In one embodiment, when J=2 and each antenna is associated with r receive beam directions, the number of rounds n is expressed by equation (1):

[0115]

number

[0116] n represents the number of rounds of measurements of the reference signal made (i.e., the cover factor), m represents the number of overlapping receive beam directions that the J antennas have, and Floor() represents downward rounding.

[0117] Here, the UE has the capability to simultaneously receive two different QCL-D related reference signals, i.e., in one round of reference signal measurement, the UE can measure reference signals in two receiving beam directions.

[0118] Here, m can represent the number of receive beams of one antenna that have an overlapping relationship with receive beams of another antenna.

[0119] The measurement result can be determined simply by having one of the antennas measure the reference signal in the overlapping receive beam direction.

[0120] Illustratively, one antenna corresponds to eight receive beam directions, ie, r=8.

[0121] When m is 2, that is, the number of receive beam directions that overlap with the receive beam directions of another antenna among the receive beam directions of one antenna shown in Figure 4 is 2. The 14 receive beam directions shown in Figure 4 can be completed by the UE through seven rounds of reference signal measurement.

[0122] Analogy: The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 1, m=1, and the UE can determine the measurement results of 15 beam directions by measuring the reference signal for 8 rounds.

[0123] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 2, m=2, and the UE can determine the measurement results of 14 beam directions by measuring the reference signal for 7 rounds.

[0124] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam directions of another antenna is 3, m=3, and the UE can determine the measurement results of 13 beam directions by measuring the reference signal for 7 rounds.

[0125] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam directions of another antenna is 4, m=4, and the UE can determine the measurement results of 12 beam directions by measuring the reference signal for 6 rounds.

[0126] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 5, m=5, and the UE can determine the measurement results of 11 beam directions by measuring the reference signal for 6 rounds.

[0127] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 6, m=6, and the UE can determine the measurement results of 10 beam directions by measuring the reference signal for 5 rounds.

[0128] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam directions of another antenna is 7, m=7, and the UE can determine the measurement results of nine beam directions by measuring the reference signal five rounds.

[0129] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 8, m=8, and the UE can determine the measurement results of 8 beam directions by measuring the reference signal four rounds.

[0130] In one possible implementation manner, the cover coefficient may be the number of overlapping receive beam directions of the J antennas. The network device can determine the number of rounds n of the reference signal measurements that the UE performs in the I receive beam directions based on the cover coefficient. The manner in which the network device determines the number of rounds n is similar to the manner in which the UE determines the number of rounds n, and will not be further described here.

[0131] As shown in FIG. 5, an embodiment of the present disclosure provides an information transmission method, which is executed by a user equipment (UE) and includes step 501: receiving a measurement configuration sent by a network device, the measurement configuration including a measurement time length for measuring a reference signal in the I receiving beam directions, and a beam scanning coefficient N for determining the measurement time length is determined based on the capability information.

[0132] Based on the received capability information, the network device determines the number n of rounds of measurements of the reference signal that the UE will perform in the I receiving beam directions.

[0133] The network device may determine a beam scanning factor N based on the number of rounds n.

[0134] The beam scan factor N can be used to calculate the measurement time length.

[0135] In one possible implementation, the number of rounds n is directly correlated with the beam scanning factor N.

[0136] In one embodiment, the beam scanning factor N is equal to the number of rounds n.

[0137] In one possible implementation, the beam scanning factor N may be a calculation parameter in the calculation rule used to calculate the measurement time length.

[0138] In one possible implementation, the beam scanning factor N is directly correlated with the measurement time length.

[0139] The network device can calculate the measurement time length based on the beam scanning factor N.

[0140] The network device determines the number of rounds n of reference signal measurements that need to be performed based on the capability information, determines a beam scanning coefficient N based on the number of rounds n, and further determines the measurement time length, thereby improving the matching degree between the measurement time length and the UE's reference signal measurements, and improving the accuracy of resource configuration.

[0141] The network device may instruct the UE on the measurement configuration to determine the measurement time domain resource, for example, the measurement time length, over which the UE performs measurements on the reference signal.

[0142] In one possible implementation, the network device transmits a reference signal within the measurement time length, so that the UE can measure I receiving beam directions within the measurement time length.

[0143] Illustratively, after receiving the coverage coefficient of the receiving beam reported by the terminal, the network device sets a beam scanning coefficient N=Beamoverlapscalingfactor associated with the measurement time length of the L1-RSRP based on SSB by the terminal.

[0144] The UE reports the measurement results based on the measurement time length instructed by the network device and the L1-RSRP measurement of the SSB. After obtaining the corresponding L1-RSRP measurement results, the network device can select the optimal beam for subsequent transmission scheduling.

[0145] As shown in FIG. 6, an embodiment of the present disclosure provides an information transmission method, which is executed by a network device and includes the following steps: step 601: receive capability information transmitted by a UE, and the capability information is used to determine the number n of rounds of reference signal measurements performed by the user equipment (UE) in I receiving beam directions, where one round of reference signal measurements includes measurements of the reference signal performed by J antennas in X receiving beam directions, and the J antennas cover the I receiving beam directions, where J is a positive integer greater than 2, X is a positive integer less than or equal to J, and I is a positive integer greater than J.

[0146] In one embodiment, the UE includes J antennas.

[0147] For example, J=2, ie, the UE includes two antennas.

[0148] In one embodiment, the UE's J antennas cover a total of I receive beam directions.

[0149] For example, a UE includes two antennas, and the receive beam of each antenna covers eight receive beam directions, and the receive beam of the two antennas covers 16 receive beam directions.

[0150] For example, if a UE includes two antennas, and the receiving beam of each antenna covers eight receiving beam directions, and the receiving beam directions of one receiving beam of the two antennas overlap, the receiving beams of the two antennas cover 15 receiving beam directions. This is an analogy and will not be described in detail.

[0151] In one embodiment, J antennas of the UE can simultaneously measure reference signals in X receive beam directions.

[0152] For example, if a UE includes two antennas, the two antennas can simultaneously measure the reference signal in the same receive beam direction, and X = 1. The two antennas can simultaneously measure the reference signal in different receive beam directions, and X = 2.

[0153] In one embodiment, the antenna comprises an antenna panel, wherein an antenna panel comprises at least one antenna array, where each antenna array comprises at least two antenna elements.

[0154] That is, the UE antenna may be an antenna panel, which may be configured with one or more antenna arrays, and different beamforming may be achieved through the antenna arrays.

[0155] In one possible implementation, one antenna can form receive beams in different directions using a beamforming scheme, and the UE can receive the reference signal transmitted by the network device through multiple receive beams obtained by the beamforming.

[0156] Here, one receive beam can correspond to one receive beam direction.

[0157] In one possible implementation, the network device includes at least one of, but is not limited to, an access network device (eg, a base station) and a core network device.

[0158] The core network device may transmit a reference signal to the UE via the access network device.

[0159] In one possible implementation, the reference signal includes, but is not limited to, an SSB, and the measurement of the reference signal may be an L1-RSRP measurement on the SSB.

[0160] In one round of signal measurement, J antennas can each measure a reference signal. In one round of signal measurement for J antennas, the receiving beam directions can be the same or different. Therefore, in one round of signal measurement, J antennas can measure X receiving beam directions, where X is greater than or equal to 1 and less than or equal to J. For example, if the receiving beam directions are all the same in one round of signal measurement for J antennas, X=1; if the receiving beam directions are different in one round of signal measurement for J antennas, X=J.

[0161] A UE may have J antennas, each corresponding to K receive beam directions. Because the receive beam directions of two antennas may overlap, the number I of receive beam directions in which the UE can actually receive a reference signal is J*K or less. That is, it should be understood that if one of two UE antennas (e.g., antenna A and antenna B) has a receive beam direction in which the receive beam direction overlaps, e.g., if the receive beam direction of one receive beam of antenna A is the same as the receive beam direction of one receive beam of antenna B, the measurement result of the reference signal in that receive beam direction can be determined simply by measuring in that receive beam direction with any of antennas A or B. Here, the receive beam directions overlap, i.e., the receive beams overlap. The receive beam directions may overlap when the difference between the receive beam directions is less than a predetermined threshold.

[0162] In some embodiments, a UE may have J (e.g., J=2) antennas, each corresponding to K (e.g., K=8) receive beam directions. Because there may be situations where the receive beam directions of two antennas overlap, the number I of receive beam directions in which the UE can actually receive reference signals is J*K or less, e.g., I=14.

[0163] Then, for the UE to complete signal measurement in I receive beam directions, it needs to perform one or more rounds of signal measurement, where each round measures X receive beam directions, where X is less than or equal to I.

[0164] For example, as shown in FIG. 4, the UE includes two antennas (antenna 1 and antenna 2, antenna 1 corresponds to beams r1 to r8, and antenna 2 corresponds to beams R1 to R8), each of which corresponds to eight receive beam directions. There may be overlap between two receive beam directions for the two antennas (the r2 receive beam of antenna 1 overlaps with the R8 receive beam direction of antenna 2, and the r1 receive beam of antenna 1 overlaps with the R7 receive beam direction of antenna 2). Therefore, the number I of receive beam directions in which the UE can actually receive the reference signal is 14, which is smaller than the total number of beams (16) for the two antennas.

[0165] In one possible implementation, the UE has the capability to simultaneously receive multiple different QCL-D related reference signals.

[0166] In one possible implementation, the UE does not have the capability to simultaneously receive multiple different QCL-D related reference signals.

[0167] Here, the reference signals of different QCL-D relationships may include reference signals of different receive beam directions.

[0168] In one possible implementation, one round of measuring the reference signal includes multiple simultaneous measurements of the reference signal, where one measurement of the reference signal can correspond to one antenna.

[0169] In one embodiment, the J antennas of the UE each support simultaneous measurements of a reference signal in the same or different receive beam directions.

[0170] In one possible implementation, one round of measurements of the reference signal includes measurements of the reference signal made simultaneously by J antennas in X directions of the receive beams.

[0171] 4, the UE can simultaneously use two antennas to measure reference signals in two receive beam directions. For example, the UE can simultaneously use antenna 1 and antenna 2 to simultaneously receive reference signals in the r8 receive beam direction and the R1 receive beam direction. Alternatively, the UE can simultaneously use antenna 1 to simultaneously receive reference signals in the r2 receive beam direction and antenna 2 to simultaneously receive reference signals in the r2 receive beam direction and the R7 receive beam direction.

[0172] In some embodiments, factors that influence the number n of rounds of reference signal measurements that the UE performs in I receive beam directions may include, but are not limited to, at least one of: whether there are overlapping receive beams among the J antennas; whether there is overlap in the receive beam directions of the overlapping receive beams; the number of overlapping receive beams that exist among the J antennas; and whether the UE supports the ability to simultaneously receive reference signals with different QCL-D relationships.

[0173] Here, the receive beam overlap may be an overlap of the receive beam directions. Whether the receive beam directions overlap can be determined based on the difference between the receive beam directions. For example, if the difference between the receive beam directions of two receive beams is smaller than a threshold, the two receive beam directions overlap; otherwise, the two receive beam directions do not overlap.

[0174] In one possible implementation, when J is greater than 3, the number of overlapping receive beams present among the J antennas may include at least one of the number of overlapping receive beams present between two antennas, the number of overlapping receive beams present between two or more antennas.

[0175] In one possible implementation, the overlap of receive beam directions may include beam coverage range overlap.

[0176] In one possible implementation, if the receive beams have the same broadcast angle, then if the receive beam directions overlap, the beam coverage ranges will also overlap.

[0177] The UE can determine the number of rounds n of measurements of the reference signal that the UE will perform in the I receive beam directions based on the above factors.

[0178] For example, as shown in Figure 4, the directions of the r2 receive beam of antenna 1 and the R8 receive beam of antenna 2 overlap, and the r1 receive beam of antenna 1 and the R7 receive beam of antenna 2 overlap, and the UE has the ability to simultaneously receive reference signals with two different QCL-D relationships. Therefore, in one round of reference signal measurement, the UE can measure reference signals in two receive beam directions. The 14 receive beam directions shown in Figure 4 can be completed by the UE through seven rounds of reference signal measurement.

[0179] The UE may send capability information to the network device to determine the number n of rounds of reference signal measurements that the network device will make.

[0180] In one possible implementation, the capability information indirectly determines the number n of rounds of reference signal measurements that the network device will perform, for example, the capability information is used to indicate the above-mentioned decision factor, and the network device calculates the number n of rounds of reference signal measurements that the network device will perform based on the decision factor.

[0181] In one embodiment, the capability information includes a receive beam coverage factor, which is used to indicate the number of rounds n, and the coverage factor is related to the number of receive beam directions that overlap with each other among the J antennas.

[0182] Here, the cover coefficient represents the number of rounds of signal measurement that the UE instructs the network device to perform to complete measurements of reference signals in I receiving beam directions. Here, the name of the cover coefficient is not limited.

[0183] The UE can directly indicate the round number n to the network device through the capability information, thereby reducing the amount of data to be transmitted and the signaling load, and also reducing the load caused by the network device calculating the round number n according to the decision factor.

[0184] In one possible implementation, the cover factor can be "Beamoverlapscalingfactor".

[0185] The following describes the coverage factor using an example where the UE has two antennas, each corresponding to eight receiving directions. The UE can send the BeamOverlapScalingFactor to the network device.

[0186] For example, the beam overlap scaling factor is 4. If the terminal's two antennas have eight fully overlapping beams (i.e., a total of eight beam directions that need to be measured), the UE can complete SSB-based L1-RSRP measurements for all receiving beams in four rounds of SSB measurement (one round of SSB measurement: two antennas can simultaneously perform SSB measurements for different receiving beam directions).

[0187] In this way, the capability information allows the network device to determine the number of measurement rounds required for the UE to measure the reference signal, which can reduce the deviation in determining the number of measurement rounds for the reference signal measurement caused by the network device not determining the UE capability, and further improve the accuracy of the network device's resource configuration.

[0188] In one embodiment, the number of rounds n is determined based on the number of receive beam directions associated with each of the antennas and the number of overlapping receive beam directions that the J antennas have.

[0189] In one possible implementation, the number of rounds n is directly correlated with the number of receive beam directions associated with each antenna.

[0190] The more receive beam directions associated with each antenna, the more rounds n of measurements that need to be taken.

[0191] In one possible implementation, the number of rounds n is negatively correlated with the determination of the number of overlapping receive beam directions that the J antennas have.

[0192] The more overlapping receive beam directions the J antennas have, the fewer the number of rounds n that need to be measured.

[0193] In one embodiment, when J=2 and each antenna is associated with r receive beam directions, the number of rounds n is expressed by equation (1), where n represents the number of rounds of measurements of the reference signal made (i.e., the cover factor), m represents the number of overlapping receive beam directions that the J antennas have, and Floor() represents downward rounding.

[0194] Here, the UE has the capability to simultaneously receive two different QCL-D related reference signals, i.e., in one round of reference signal measurement, the UE can measure reference signals in two receiving beam directions.

[0195] Here, m can represent the number of receive beam directions in which the receive beam of one antenna has an overlapping relationship with the receive beam of another antenna.

[0196] The measurement result can be determined simply by having one of the antennas measure the reference signal in the overlapping receive beam direction.

[0197] Illustratively, one antenna corresponds to eight receive beam directions, ie, r=8.

[0198] When m is 2, that is, the number of receive beam directions that overlap with the receive beam directions of another antenna among the receive beam directions of one antenna shown in Figure 4 is 2. The 14 receive beam directions shown in Figure 4 can be completed by the UE through seven rounds of reference signal measurement.

[0199] Analogy: The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 1, m=1, and the UE can determine the measurement results of 15 beam directions by measuring the reference signal for 8 rounds.

[0200] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 2, m=2, and the UE can determine the measurement results of 14 beam directions by measuring the reference signal for 7 rounds.

[0201] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam directions of another antenna is 3, m=3, and the UE can determine the measurement results of 13 beam directions by measuring the reference signal for 7 rounds.

[0202] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam directions of another antenna is 4, m=4, and the UE can determine the measurement results of 12 beam directions by measuring the reference signal for 6 rounds.

[0203] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 5, m=5, and the UE can determine the measurement results of 11 beam directions by measuring the reference signal for 6 rounds.

[0204] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 6, m=6, and the UE can determine the measurement results of 10 beam directions by measuring the reference signal for 5 rounds.

[0205] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam directions of another antenna is 7, m=7, and the UE can determine the measurement results of nine beam directions by measuring the reference signal five rounds.

[0206] The number of receiving beam directions in one antenna that have an overlapping relationship with the receiving beam direction of another antenna is 8, m=8, and the UE can determine the measurement results of 8 beam directions by measuring the reference signal four rounds.

[0207] In one possible implementation manner, the cover coefficient may be the number of overlapping receive beam directions of the J antennas. The network device can determine the number of rounds n of the reference signal measurements that the UE performs in the I receive beam directions based on the cover coefficient. The manner in which the network device determines the number of rounds n is similar to the manner in which the UE determines the number of rounds n, and will not be further described here.

[0208] As shown in FIG. 7, an information transmission method according to an embodiment of the present disclosure is provided, which is performed by a network device and includes the following steps: Step 701: Determine a beam scanning factor N based on the capability information; Step 702: Based on the beam scanning coefficient N, the UE determines a measurement time length for measuring reference signals in the I receiving beam directions.

[0209] Based on the received capability information, the network device determines the number n of rounds of measurements of the reference signal that the UE will perform in the I receiving beam directions.

[0210] The network device may determine a beam scanning factor N based on the number of rounds n.

[0211] The beam scan factor N can be used to calculate the measurement time length.

[0212] In one possible implementation, the number of rounds n is directly correlated with the beam scanning factor N.

[0213] In one embodiment, the beam scanning factor N is equal to the number of rounds n.

[0214] In one possible implementation, the beam scanning factor N may be a calculation parameter in the calculation rule used to calculate the measurement time length.

[0215] In one possible implementation, the beam scanning factor N is directly correlated with the measurement time length.

[0216] The network device can calculate the measurement time length based on the beam scanning factor N.

[0217] In one embodiment, the beam scanning factor N is equal to the number of rounds n.

[0218] The network device determines the number of rounds n of reference signal measurements that need to be performed based on the capability information, determines a beam scanning coefficient N based on the number of rounds n, and further determines the measurement time length, thereby improving the matching degree between the measurement time length and the UE's reference signal measurements, and improving the accuracy of resource configuration.

[0219] As shown in FIG. 8 , an information transmission method according to an embodiment of the present disclosure is provided, which is performed by a network device and includes the following steps: Step 801: Send a measurement configuration to the UE, where the measurement configuration includes at least the measurement time length.

[0220] The network device may instruct the UE on the measurement configuration to determine the measurement time domain resource, for example, the measurement time length, over which the UE performs measurements on the reference signal.

[0221] In one possible implementation, the network device transmits a reference signal within the measurement time length, so that the UE can measure I receiving beam directions within the measurement time length.

[0222] Illustratively, after receiving the coverage coefficient of the receiving beam reported by the terminal, the network device sets a beam scanning coefficient N=Beamoverlapscalingfactor associated with the measurement time length of the L1-RSRP based on SSB by the terminal.

[0223] The UE reports the measurement results based on the measurement time length instructed by the network device and the L1-RSRP measurement of the SSB. After obtaining the corresponding L1-RSRP measurement results, the network device can select the optimal beam for subsequent transmission scheduling.

[0224] The following provides a specific example in combination with any of the above embodiments: The terminal reports the coverage factor of the antenna configuration, and the network schedules transmissions and measurements to the terminal based on the corresponding capabilities.

[0225] Example 1: The terminal reports the coverage factor of the receiving beam of the antenna configuration, Beamoverlapscalingfactor, based on its own capabilities.

[0226] The values ​​of BeamOverlapScalingFactor are [4, 5, 6, 7, 8], which correspond to 4 to 8 terminal SSB measurement times, respectively.

[0227] The default BeamOverlapScalingFactor is 8, i.e., the terminal does not receive beam coverage, and the terminal needs to complete 8 SSB measurements to complete SSB-based L1-RSRP measurements.

[0228] For the case where BeamOverlapScalingFactor=4, the two antenna panels of the terminal provide full coverage, and the terminal can complete SSB-based L1-RSRP measurements of all receiving beams with only four SSB measurements.

[0229] Example 2: After receiving the coverage factor of the receiving beam reported by the terminal, the network sets the beam scanning factor N=BeamOverlapScalingFactor for the terminal's SSB-based L1-RSRP measurement time. Before the L1-RSRP measurement report is completed, the network cannot obtain the terminal's L1-RSRP measurement result. After obtaining the corresponding L1-RSRP measurement result, the network can select the optimal beam for subsequent transmission scheduling.

[0230] As shown in FIG. 9, an embodiment of the present disclosure provides an information transmission device 100, which is installed in a user equipment (UE), and includes the following transceiving modules 110: The transceiver module 110 is configured to transmit capability information, which is used by the network device to determine the number n of rounds of reference signal measurements that the UE will perform in I receive beam directions, wherein one round of reference signal measurements includes measurements of the reference signal performed by J antennas in X receive beam directions, and the J antennas cover the I receive beam directions, where J is a positive integer greater than 2, X is a positive integer less than or equal to J, and I is a positive integer greater than J.

[0231] In one embodiment, the capability information includes a coverage factor of a receive beam and is used to indicate the number of rounds n.

[0245]

number

An embodiment of the present disclosure provides a communication device, including: memories for storing processor-executable instructions; and processors respectively coupled to the memories, wherein the processors are configured to perform the information transmission method provided by any of the above technical solutions.

[0256] Here, the communication device includes a UE or a network element, and the network element may be any one of the first to fourth network elements.

[0257] The processor is connected to the memory via a bus or the like and is used to read an executable program stored in the memory, for example, at least one of the methods shown in FIGS.
