TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wireless communication, and more particularly, to an information transmission method and apparatus, a communication device, and a storage medium. BACKGROUND

[0002] In the evolution of the 5th Generation (5G) mobile communication, due to the adoption of beamforming technology in the FR2 millimeter wave frequency band, when a user equipment (UE) receives a wireless signal, it no longer uses an omnidirectional antenna as in the FR1 low frequency band, but additionally introduces the management of the receiving beam to adopt the best receiving beam for reception, to achieve greater uplink coverage and better transmission rate. At the same time, due to the introduction of the concept of beam, the spatial dimension is further introduced into the transmission of the UE, that is, the physical resources at the same time and frequency can be further multiplexed by different beams.

[0089] Reference is made to Figure 1 which shows a structure diagram of a wireless communication system provided by the embodiments of the disclosure. As shown in Figure 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include a plurality of UEs 11 and a plurality of network devices 12.

[0090] The wireless communication system can be a 4th generation mobile communication (4G) system, also known as a Long Term Evolution (LTE) system, or the wireless communication system can also be a 5G system, also known as a new radio (NR) system or a 5G NR system. Alternatively, the wireless communication system can also be a further next generation system of the 5G system. In the 5G system, the access network can be referred to as a new generation radio access network (NG-RAN). Alternatively, the MTC system.

[0091] The UE 11 can be a device that provides voice and / or data connectivity to a user. The UE 11 can communicate with one or more core networks (CNs) via a Radio Access Network (RAN), and the UE 11 can be an Internet of Things (IoT) UE, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT UE, for example, which can be fixed, portable, pocketable, hand-held, computer-embedded, or in-vehicle. For example, a Station (STA), a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote UE, an access UE, a user terminal, a user agent, a user device, or a user equipment (UE). Alternatively, the UE 11 can also be a device of an unmanned aerial vehicle. Alternatively, the UE 11 can also be a vehicle-mounted device, for example, it can be a vehicle-mounted computer with wireless communication function, or a wireless communication device externally connected to the vehicle-mounted computer. Alternatively, the UE 11 can also be a roadside device, for example, it can be a street lamp, a signal lamp, or other roadside devices with wireless communication function, and the like.

[0092] The network device 12 can include an access network device. Optionally, the network device 12 can also include a core network device. The access network device can be an evolved access device (eNB) used in a 4G system. Alternatively, it can also be an access device (gNB) using a centralized and distributed architecture in a 5G system. When the access network device uses a centralized and distributed architecture, it usually includes a central unit (CU) and at least two distributed units (DUs). The central unit is provided with a protocol stack of a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and a Media Access Control (MAC) layer; the distributed unit is provided with a Physical (PHY) layer protocol stack, and the specific implementation of the access network device is not limited in the embodiments of the present disclosure.

[0093] The network device 12 and the UE 11 can establish a wireless connection through a wireless air interface. In different embodiments, the wireless air interface is a wireless air interface based on a fourth-generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth-generation mobile communication network technology (5G) standard, such as the wireless air interface is a new air interface; or the wireless air interface can also be a wireless air interface based on a more next-generation mobile communication network technology standard of 5G.

[0094] As shown in Figure 2 , the UE adopts a receiving beam scanning manner to achieve better coverage of the receiving angle. At present, the antenna of the UE in the FR2 frequency band adopts an 8-receiving beam coverage 120° range manner, that is, the UE generates 8 beams through beamforming, each beam points to a beam direction, and realizes 120° beam coverage. As shown in Figure 2 , r1-r8 represent 8 receiving beams generated by the UE through beamforming, wherein each receiving beam corresponds to a receiving beam direction.

[0095] In the 3GPP standard version 16 (Rel-16), the UE capability indicated by simultaneousReceptionDiffTypeD-r16 is introduced, which is used to indicate whether the UE can simultaneously receive two reference signals with different QCL-D relationships. The UE can be configured with two antenna panels in FR2, and the simultaneous reception of the antenna arrays at different positions on the two antenna panels is used to support the terminal to realize the capability of simultaneousReceptionDiffTypeD-r16 (that is, the capability of simultaneously receiving two reference signals with different QCL-D relationships). As shown in Figure 2 , each antenna panel basically adopts an 8-receiving beam coverage 120° scheme. simultaneousReceptionDiffTypeD-r16 can only indicate whether the UE can receive in different directions, and the indication of the actual capability of the UE is not clear, which leads to the unclear indication of the receiving capability of the corresponding UE, and the base station cannot accurately judge the actual situation of the receiving capability of the terminal. The two antenna panels of the actual terminal can have three different situations of no overlap, partial overlap and complete overlap of the beams generated by the two antenna panels according to different implementation schemes.

[0096] The current UE reporting cannot realize the actual overlap of the antenna beams, and the base station cannot clearly judge the actual receiving capability of the UE, which causes the base station to not fully consider the resource scheduling of the UE reference signal measurement, and the base station can configure too much measurement time, causing waste of time domain resources.

[0097] Therefore, how to improve the accuracy of base station resource configuration for beamforming-based UEs and improve resource utilization efficiency is an urgent problem to be solved.

[0098] As Figure 3 shown, the embodiment of the present disclosure provides an information transmission method, wherein the method is performed by a user equipment (UE) and comprises the following steps:

[0099] Step 301: sending capability information of the UE to a network device, wherein the capability information is used for the network device to determine a number n of rounds of reference signal measurement performed by the UE in I receiving beam directions, wherein one round of the reference signal measurement comprises measurement of the reference signal performed by J antennas in X receiving beam directions, J antennas cover the I receiving beam directions, 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.

[0100] In one embodiment, the UE comprises J antennas.

[0101] For example, J = 2, that is, the UE comprises two antennas.

[0102] In one embodiment, the J antennas of the UE cover the I receiving beam directions.

[0103] For example, the UE comprises two antennas, and the receiving beam of each antenna covers 8 receiving beam directions, and the receiving beams of the two antennas cover 16 receiving beam directions.

[0104] For example, the UE comprises two antennas, and the receiving beam of each antenna covers 8 receiving beam directions, and the receiving beam directions of one receiving beam of the two antennas overlap, so that the receiving beams of the two antennas cover 15 receiving beam directions. By analogy, no further description is given.

[0105] In one embodiment, the J antennas of the UE can simultaneously perform reference signal measurement in X receiving beam directions.

[0106] For example, the UE comprises two antennas, and the two antennas can simultaneously perform reference signal measurement on the same receiving beam direction, in which case X = 1. The two antennas can simultaneously perform reference signal measurement on different receiving beam directions, in which case X = 2.

[0107] In one example, the antenna comprises an antenna panel. One antenna panel comprises at least one antenna array, and each antenna array comprises at least two antenna elements.

[0108] That is, the antennas of the UE can be antenna panels. An antenna panel can be composed of one or more antenna arrays. Different beams can be formed by the antenna arrays through beamforming. In one possible implementation, one antenna can form different directional receiving beams through beamforming. The UE can receive the reference signal transmitted by the network device through multiple receiving beams obtained through beamforming.

[0109] For example, one receiving beam can correspond to one receiving beam direction. In one possible implementation, the network device includes, but is not limited to, at least one of the following:

[0110] An access network device (such as a base station);

[0111] A core network device.

[0112] The core network device can transmit the reference signal to the UE through the access network device.

[0113] In one possible implementation, the reference signal includes, but is not limited to, an SSB. The reference signal measurement can be an L1-RSRP measurement for the SSB.

[0114] In one round of signal measurement, J antennas can respectively perform measurement on the reference signal. The receiving beam directions of the J antennas in one round of signal measurement can be the same or different. Therefore, in one round of signal measurement, the J antennas can measure X receiving beam directions, X is greater than or equal to 1 and less than or equal to J. For example, when the receiving beam directions of the J antennas in one round of signal measurement are the same, X = 1; when the receiving beam directions of the J antennas in one round of signal measurement are different, X = J.

[0115] The UE can have J antennas, each of which corresponds to K receiving beam directions. Since there can be overlapping or the like between the receiving beam directions of two antennas, the number I of the receiving beam directions that the UE can actually receive the reference signal is less than or equal to J*K. It can be understood that if there is overlapping between the receiving beam directions of two antennas (for example, antenna A and antenna B) of the UE, for example, the receiving beam direction of one receiving beam of antenna A is the same as the receiving beam direction of one receiving beam of antenna B, then only one of antenna A or antenna B needs to perform measurement in the receiving beam direction to determine the measurement result of the reference signal in the receiving beam direction. Here, the receiving beam directions overlap, that is, the receiving beams overlap. The receiving beam directions overlap can mean that the difference between the receiving beam directions is less than a predetermined threshold.

[0116] In some embodiments, the UE can have J (e.g., J=2) antennas, each of which corresponds to K (e.g., K=8) receive beam directions. Since there can be overlap between the receive beam directions of the two antennas, the number of receive beam directions I that the UE can actually receive the reference signals is less than or equal to J*K, e.g., I=14.

[0117] Then, the UE completes the signal measurement of the I receive beam directions in one or more rounds of signal measurement. Each round measures X receive beam directions. Thus, X is less than or equal to I. For example, if the UE has two antennas (antenna 1 and antenna 2, where antenna 1 corresponds to beams r1-r8 and antenna 2 corresponds to beams R1-R8), each of which corresponds to 8 receive beam directions, and there is overlap between the receive beam directions of the two antennas (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), then the number of receive beam directions I that the UE can actually receive the reference signals is 14, which is less than the total number of beams 16 of the two antennas. Figure 4 As described above, the UE includes two antennas (antenna 1 and antenna 2, where antenna 1 corresponds to beams r1-r8 and antenna 2 corresponds to beams R1-R8), each of which corresponds to 8 receive beam directions. There is overlap between the receive beam directions of the two antennas (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), thus the number of receive beam directions I that the UE can actually receive the reference signals is 14, which is less than the total number of beams 16 of the two antennas.

[0118] In one possible implementation, the UE is capable of simultaneously receiving reference signals of multiple different QCL-D relationships.

[0119] In one possible implementation, the UE is not capable of simultaneously receiving reference signals of multiple different QCL-D relationships.

[0120] Here, the reference signals of different QCL-D relationships can include reference signals of different receive beam directions.

[0121] In one possible implementation, one round of the reference signal measurement includes multiple reference signal measurements performed simultaneously. Each of the multiple reference signal measurements can correspond to one antenna.

[0122] In one embodiment, the J antennas of the UE support simultaneous measurement of reference signals in the same or different receive beam directions, respectively.

[0123] In one possible implementation, one round of the reference signal measurement includes measurement of the reference signals in X receive beam directions by the J antennas simultaneously.

[0124] For example, if the UE has two antennas (antenna 1 and antenna 2, where antenna 1 corresponds to beams r1-r8 and antenna 2 corresponds to beams R1-R8), each of which corresponds to 8 receive beam directions, and there is overlap between the receive beam directions of the two antennas (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), then the number of receive beam directions I that the UE can actually receive the reference signals is 14, which is less than the total number of beams 16 of the two antennas. Figure 4The UE can perform the reference signal measurement in two receive beam directions simultaneously using two antennas. For example, the UE can use antenna 1 and antenna 2 to receive the reference signal in the r8 receive beam direction simultaneously, and to receive the reference signal in the R1 receive beam direction simultaneously. Or, the UE can use antenna 1 to receive the reference signal in the r2 receive beam direction, and use antenna 2 to receive the reference signal in the R7 receive beam direction simultaneously.

[0125] In some embodiments, the factors that affect the number n of rounds of reference signal measurement performed by the UE in the I receive beam directions can include, but are not limited to, at least one of the following:

[0126] whether there are overlapping receive beams between the J antennas; wherein the receive beam directions of the overlapping receive beams overlap;

[0127] the number of overlapping receive beams between the J antennas;

[0128] whether the UE has the capability of simultaneously receiving reference signals with different QCL-D relationships.

[0129] Here, the receive beam overlap can be the receive beam direction overlap. Whether the receive beam directions overlap can be determined according to the difference between the receive beam directions. For example, if the difference between the receive beam directions of two receive beams is less than a threshold, then the two receive beam directions overlap, otherwise it is determined that the two receive beam directions do not overlap.

[0130] In one possible implementation, if J is greater than 3, the number of overlapping receive beams between the J antennas can include at least one of the following: the number of overlapping receive beams between two antennas; the number of overlapping receive beams between more than two antennas.

[0131] In one possible implementation, the receive beam direction overlap can include: the beam coverage overlap.

[0132] In one possible implementation, the broadcast angles of the receive beams are the same, then when the receive beam directions overlap, the beam coverages also overlap.

[0133] The UE can determine the number n of rounds of reference signal measurement performed by the UE in the I receive beam directions based on the above factors.

[0134] For example, as shown in FIG. 2, the UE can use antenna 1 to receive the reference signal in the r2 receive beam direction, and use antenna 2 to receive the reference signal in the R7 receive beam direction simultaneously. Figure 4 The r2 receive beam of antenna 1 and the R8 receive beam of antenna 2 overlap, the r1 receive beam of antenna 1 and the R7 receive beam of antenna 2 overlap, and the UE has the capability of simultaneously receiving reference signals with two different QCL-D relationships. Therefore, in one round of reference signal measurement, the UE can measure the reference signals in two receive beam directions.Figure 4 The UE can complete the 14 receive beam directions by 7 rounds of reference signal measurement.

[0135] The UE can send the capability information to the network device for the network device to determine the number of rounds n of reference signal measurement to be performed.

[0136] In one possible implementation, the capability information is used by the network device to indirectly determine the number of rounds n of reference signal measurement to be performed. For example, the capability information is used to indicate the determination factors, and the network device calculates the number of rounds n of reference signal measurement to be performed based on the determination factors.

[0137] In one embodiment, the capability information includes a coverage factor of receive beams, which is used to indicate the number of rounds n. The coverage factor is associated with the number of receive beam directions that are mutually overlapped among the J antennas.

[0138] Here, the coverage factor indicates the number of rounds of signal measurement that the UE needs to perform to complete the reference signal measurement of I receive beam directions. The name of the coverage factor is not limited here.

[0139] The UE can directly indicate the number of rounds n to the network device through the capability information. In this way, the amount of data transmitted can be reduced, and the signaling load can be reduced. The load of the network device caused by calculating the number of rounds n through determination factors can also be reduced.

[0140] In one possible implementation, the coverage factor can be “Beamoverlapscalingfactor”.

[0141] The coverage factor is illustrated below with an example in which the UE has two antennas, and one antenna corresponds to 8 receive directions. The UE can send the Beamoverlapscalingfactor to the network device. Exemplarily, the default Beamoverlapscalingfactor = 8, which means that the terminal needs to complete 8 rounds of SSB measurement (one round of SSB measurement is performed by two antennas at the same time) to complete the SSB-based L1-RSRP measurement. This means that the two antenna panels of the UE do not have coverage of receive beams (i.e., a total of 16 beam directions need to be measured),

[0142] Exemplarily, the Beamoverlapscalingfactor = 4. The 8 beams of the two antennas of the terminal are completely overlapped (i.e., a total of 8 beam directions need to be measured), and the UE can complete the SSB-based L1-RSRP measurement of all receive beams in 4 rounds of SSB measurement (one round of SSB measurement can be: two antennas simultaneously perform SSB measurement for different receive beam directions).

[0143] Thus, by the capability information, the network device can determine the measurement rounds required by the UE for the reference signal measurement. The measurement round determination deviation of the reference signal measurement caused by the network device not determining the UE capability is reduced, and thus the accuracy of the network device configuring the resource can be improved.

[0144] In one embodiment, the number of rounds n is determined according to the number of receiving beam directions associated with each of the antennas and the number of overlapping receiving beam directions possessed by the J antennas.

[0145] In one possible implementation, the number of rounds n is positively correlated with the number of receiving beam directions associated with each of the antennas.

[0146] The more the number of receiving beam directions associated with each of the antennas, the more the number of rounds n required for measurement.

[0147] In one possible implementation, the number of rounds n is negatively correlated with the number of overlapping receiving beam directions possessed by the J antennas.

[0148] The more the number of overlapping receiving beam directions possessed by the J antennas, the less the number of rounds n required for measurement.

[0149] In one embodiment, when J = 2 and each of the antennas is associated with r receiving beam directions, the number of rounds n is expressed by expression (1):

[0150] n = r - Floor(m / 2) (1)

[0151] wherein n represents the number of rounds n of the reference signal measurement performed (i.e., the coverage factor), m represents the number of overlapping receiving beam directions possessed by the J antennas, and Floor() represents the floor function.

[0152] Here, the UE has the capability of being able to simultaneously receive reference signals of two different QCL-D relationships, i.e., in one round of reference signal measurement, the UE can measure the reference signals of two receiving beam directions.

[0153] Here, m can represent the number of receiving beam directions of one antenna that have an overlapping relationship with the receiving beam directions of another antenna.

[0154] In the overlapping receiving beam directions, only any one of the antennas needs to perform the reference signal measurement to determine the measurement result.

[0155] For example, one antenna corresponds to 8 receiving beam directions, i.e., r = 8.

[0156] If m is 2, i.e., the number of receiving beam directions of one antenna that have an overlapping relationship with the receiving beam directions of another antenna is 2, as shown in Figure 4 the expression.Figure 4 The UE can complete the 14 receive beam directions shown by 7 rounds of reference signal measurement.

[0157] By analogy:

[0158] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 1, m = 1, and then the UE needs to perform 8 rounds of reference signal measurement to determine the measurement results of 15 beam directions.

[0159] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 2, m = 2, and then the UE needs to perform 7 rounds of reference signal measurement to determine the measurement results of 14 beam directions.

[0160] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 3, m = 3, and then the UE needs to perform 7 rounds of reference signal measurement to determine the measurement results of 13 beam directions.

[0161] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 4, m = 4, and then the UE needs to perform 6 rounds of reference signal measurement to determine the measurement results of 12 beam directions.

[0162] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 5, m = 5, and then the UE needs to perform 6 rounds of reference signal measurement to determine the measurement results of 11 beam directions.

[0163] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 6, m = 6, and then the UE needs to perform 5 rounds of reference signal measurement to determine the measurement results of 10 beam directions.

[0164] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 7, m = 7, and then the UE needs to perform 5 rounds of reference signal measurement to determine the measurement results of 9 beam directions.

[0165] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 8, m = 8, and then the UE needs to perform 4 rounds of reference signal measurement to determine the measurement results of 8 beam directions.

[0166] In a possible implementation, the coverage factor can be a number of overlapping receiving beam directions that the J antennas have. The network device can determine, according to the coverage factor, the number n of rounds of reference signal measurement performed by the UE in the I receiving beam directions. The network device can determine the number n of rounds in a similar manner as the UE, which is not described herein again.

[0167] As shown in Figure 5 The embodiments of the present disclosure provide an information transmission method, which is performed by a user equipment (UE), and includes the following steps.

[0168] Step 501: receiving a measurement configuration sent by a network device, wherein the measurement configuration includes a measurement duration of reference signal measurement in the I receiving beam directions, wherein a beam scanning coefficient N used to determine the measurement duration is determined based on the capability information.

[0169] The network device determines, according to the received capability information, the number n of rounds of reference signal measurement performed by the UE in the I receiving beam directions.

[0170] The network device can determine the beam scanning coefficient N according to the number n of rounds.

[0171] The beam scanning coefficient N can be used to calculate the measurement duration.

[0172] In a possible implementation, the number n of rounds is positively correlated with the beam scanning coefficient N.

[0173] In an embodiment, the beam scanning coefficient N is equal to the number n of rounds.

[0174] In a possible implementation, the beam scanning coefficient N can be a calculation parameter in a calculation rule used to calculate the measurement duration.

[0175] In a possible implementation, the beam scanning coefficient N is positively correlated with the measurement duration.

[0176] The network device can calculate the measurement duration based on the beam scanning coefficient N.

[0177] The network device determines the number n of rounds of reference signal measurement that needs to be performed through the capability information, determines the beam scanning coefficient N according to the number n of rounds, and then determines the measurement duration, thereby improving the matching degree of the measurement duration and the reference signal measurement performed by the UE, and improving the accuracy of resource configuration.

[0178] The network device can indicate the measurement configuration to the UE, so that the UE determines the measurement time domain resource, such as the measurement duration, of the reference signal measurement.

[0179] In a possible implementation, the network device can send a reference signal for the UE to perform measurement in I receive beam directions within a measurement duration.

[0180] For example, after receiving the coverage factor of the receive beam reported by the terminal, the network device configures the beam scanning factor N associated with the measurement duration of the L1-RSRP of the SSB based on the SSB, i.e., N = Beamoverlapscalingfactor.

[0181] The UE performs measurement of the L1-RSRP of the SSB based on the measurement duration indicated by the network device and reports the measurement result. After obtaining the corresponding measurement result of the L1-RSRP, the network device can select the best beam for subsequent transmission scheduling.

[0182] As shown in Figure 6 The present disclosure provides an information transmission method, which is performed by a network device and includes the following steps.

[0183] Step 601: receiving capability information sent by a UE, wherein the capability information is used to determine the number n of rounds of reference signal measurement performed by the UE in I receive beam directions, wherein one round of the reference signal measurement includes measurement of the reference signal performed by J antennas in X receive beam directions, J antennas cover the I receive beam directions, 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.

[0184] In one embodiment, the UE includes J antennas.

[0185] For example, J = 2, i.e., the UE includes two antennas.

[0186] In one embodiment, the J antennas of the UE cover the I receive beam directions.

[0187] For example, the UE includes two antennas, and the receive beam of each antenna covers 8 receive beam directions, and the receive beams of the two antennas cover 16 receive beam directions.

[0188] For example, the UE includes two antennas, and the receive beam of each antenna covers 8 receive beam directions, and the receive beams of the two antennas cover 15 receive beam directions. Similarly, the above is not repeated.

[0189] In one embodiment, the J antennas of the UE can simultaneously perform reference signal measurement in X receive beam directions.

[0190] For example, the UE contains two antennas, the two antennas can simultaneously perform reference signal measurement for the same receive beam direction, in which case X = 1. The two antennas can simultaneously perform reference signal measurement for different receive beam directions, in which case X = 2.

[0191] In one embodiment, the antennas include: an antenna panel. One antenna panel includes at least one antenna array, wherein each antenna array includes at least two antenna elements.

[0192] That is, the antennas of the UE can be an antenna panel. The antenna panel can be composed of one or more antenna arrays. Different receive beams can be formed by the antenna arrays through beamforming.

[0193] In one possible implementation, one antenna can form receive beams in different directions through beamforming. The UE can receive the reference signals sent by the network device through multiple receive beams obtained through beamforming.

[0194] Here, one receive beam can correspond to one receive beam direction.

[0195] In one possible implementation, the network device includes but is not limited to at least one of the following:

[0196] An access network device (such as a base station);

[0197] A core network device.

[0198] The core network device can send the reference signals to the UE through the access network device.

[0199] In one possible implementation, the reference signal includes but is not limited to SSB. The reference signal measurement can be L1-RSRP measurement for SSB.

[0200] In one round of signal measurement, J antennas can respectively perform reference signal measurement. The receive beam directions of the J antennas in one round of signal measurement can be the same or different. Therefore, in one round of signal measurement, the J antennas can measure X receive beam directions, X is greater than or equal to 1 and less than or equal to J. For example, when the receive beam directions of the J antennas in one round of signal measurement are the same, X = 1; when the receive beam directions of the J antennas in one round of signal measurement are different, X = J.

[0201] A UE can have J antennas, each corresponding to K receive beam directions. Since the receive beam directions of two antennas may overlap, the actual number I of receive beam directions that the UE can receive the reference signal from is less than or equal to J*K. That is, if one of the receive beam directions of two antennas of the UE (e.g., antenna A and antenna B) overlaps—for example, if the receive beam direction of one receive beam of antenna A is the same as that of one receive beam of antenna B—then only one antenna (A or B) needs to be measured in that receive beam direction to determine the measurement result of the reference signal in that receive beam direction. Here, receive beam direction overlap is defined as a difference in receive beam directions less than a predetermined threshold.

[0202] In some embodiments, the UE may have J antennas (e.g., J=2), each antenna corresponding to K (e.g., K=8) receive beam directions. Since the receive beam directions of two antennas may overlap, the actual number of receive beam directions I that the UE can receive the reference signal from is less than or equal to J*K, for example, I=14. Therefore, the UE needs to perform one or more rounds of signal measurement to complete signal measurements in I receive beam directions. Each round measures X receive beam directions. Therefore, X is less than or equal to I.

[0203] For example, such as Figure 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), each antenna corresponding to 8 receiving beam directions. Two receiving beam directions of the two antennas may overlap (the r2 receiving beam of antenna 1 overlaps with the R8 receiving beam of antenna 2, and the r1 receiving beam of antenna 1 overlaps with the R7 receiving beam of antenna 2). Therefore, the actual number of receiving beam directions I that the UE can receive the reference signal from is 14, which is less than the total number of beams (16) of the two antennas.

[0204] In one possible implementation, the UE is capable of simultaneously receiving multiple reference signals with different QCL-D relationships.

[0205] In one possible implementation, the UE is not capable of simultaneously receiving multiple reference signals with different QCL-D relationships.

[0206] Here, reference signals for different QCL-D relationships can include reference signals for different receiving beam directions.

[0207] In one possible implementation, a round of reference signal measurement includes multiple simultaneous reference signal measurements. Each reference signal measurement may correspond to one antenna.

[0208] In one embodiment, the J antennas of the UE support simultaneous measurements of reference signals in the same or different receive beam directions, respectively.

[0209] In one possible implementation, one round of the reference signal measurements comprises the measurements of the reference signals in the X receive beam directions by the J antennas simultaneously.

[0210] For example, as Figure 4 mentioned, the UE can simultaneously employ two antennas to simultaneously measure reference signals in two receive beam directions, respectively. For example, the UE can simultaneously employ antenna 1 and antenna 2 to simultaneously receive reference signals in r8 receive beam direction, respectively, and simultaneously receive reference signals in R1 receive beam direction. Or, the UE can simultaneously employ antenna 1 to receive reference signals in r2 receive beam direction, and simultaneously employ antenna 2 to receive reference signals in r2 receive beam direction and R7 receive beam direction, respectively.

[0211] In some embodiments, the factors that affect the number n of rounds of reference signal measurements by the UE in the I receive beam directions can include, but are not limited to, at least one of the following:

[0212] whether there are overlapping receive beams among the J antennas; wherein the receive beam directions of the overlapping receive beams overlap;

[0213] the number of overlapping receive beams among the J antennas;

[0214] whether the UE supports the capability of simultaneously receiving reference signals with different QCL-D relationships.

[0215] Here, the receive beam overlap can be the receive beam direction overlap. Whether the receive beam directions overlap can be determined according to the difference between the receive beam directions. For example, if the difference between the receive beam directions of two receive beams is less than a threshold, then the two receive beam directions overlap, otherwise it is determined that the two receive beam directions do not overlap.

[0216] In one possible implementation, if J is greater than 3, the number of overlapping receive beams among the J antennas can include at least one of the following: the number of overlapping receive beams between two antennas; the number of overlapping receive beams between more than two antennas.

[0217] In one possible implementation, the receive beam direction overlap can include: beam coverage overlap.

[0218] In one possible implementation, the broadcast angles of the receive beams are the same, then when the receive beam directions overlap, the beam coverages also overlap.

[0219] The UE can determine the number of rounds n of reference signal measurements to be performed in I receiving beam directions based on the above factors.

[0220] For example, such as Figure 4 The receiving beams of antenna 1 (r2) and antenna 2 (R8) overlap, and the receiving beams of antenna 1 (r1) and antenna 2 (R7) overlap. Furthermore, the UE has the capability to simultaneously receive two reference signals with different QCL-D relationships. Therefore, in one round of reference signal measurement, the UE can measure reference signals in two receiving beam directions. Figure 4 The 14 receiving beam directions shown can be measured by the UE using 7 rounds of reference signals.

[0221] The UE can send capability information to the network device so that the network device can determine the number of rounds n of reference signal measurements to be performed.

[0222] In one possible implementation, the capability information is used by the network device to indirectly determine the number of rounds n of reference signal measurements to be performed. For example, the capability information is used to indicate the aforementioned determining factors, and the number of rounds n of reference signal measurements to be performed is calculated by the network device based on these determining factors.

[0223] In one embodiment, the capability information includes: a coverage factor of the received beam, used to indicate the number of rounds n; wherein the coverage factor is associated with the number of received beam directions that overlap between the J antennas.

[0224] Here, the coverage factor represents the number of rounds of signal measurement that the UE indicates to the network device is required to complete the reference signal measurement in I receive beam directions. The name of the coverage factor is not specified here.

[0225] The UE can directly indicate the number of rounds n to the network device using capability information. This reduces the amount of data transmitted and lowers the signaling load. It also reduces the load on the network device from calculating the number of rounds n based on deterministic factors.

[0226] In one possible implementation, the coverage factor could be "Beamoverlapscalingfactor".

[0227] The following example illustrates the coverage factor using a UE with two antennas, each corresponding to eight receiving directions. The UE can send the Beamoverlapscalingfactor to the network device.

[0228] For example, Beamoverlapscalingfactor = 4. Two antennas of the terminal have 8 beams completely overlapping (i.e. totally 8 beam directions need to be measured), the UE can complete the SSB-based L1-RSRP measurement of all the receive beam directions in 4 rounds of SSB measurement (one round of SSB measurement can be: two antennas simultaneously perform SSB measurement for different receive beam directions).

[0229] In this way, through the capability information, the network device can determine the number of measurement rounds required by the UE to perform the reference signal measurement. The number of measurement rounds of the reference signal measurement caused by the network device being unable to determine the UE capability is reduced, and in turn the accuracy of the network device configuring resources can be improved.

[0230] In one embodiment, the number of rounds n is determined according to the number of receive beam directions associated with each of the antennas and the number of overlapping receive beam directions possessed by the J antennas.

[0231] In one possible implementation, the number of rounds n is positively correlated with the number of receive beam directions associated with each antenna.

[0232] The more the number of receive beam directions associated with each antenna, the more the number of rounds n required for measurement.

[0233] In one possible implementation, the number of rounds n is negatively correlated with the number of overlapping receive beam directions possessed by the J antennas.

[0234] The more the number of overlapping receive beam directions possessed by the J antennas, the less the number of rounds n required for measurement.

[0235] In one embodiment, when J = 2 and each antenna is associated with r receive beam directions, the number of rounds n is expressed by expression (1); wherein n represents the number of rounds n of the reference signal measurement performed (i.e. coverage factor), m represents the number of overlapping receive beam directions possessed by the J antennas, and Floor() represents rounding down.

[0236] Here, the UE has the capability of being able to simultaneously receive reference signals of two different QCL-D relationships, that is, in one round of reference signal measurement, the UE can measure the reference signals of two receive beam directions.

[0237] Here, m can represent the number of receive beam directions of one antenna that have an overlapping relationship with the receive beam of another antenna.

[0238] In the overlapping receive beam direction, only any one antenna needs to perform the reference signal measurement to determine the measurement result.

[0239] For example, one antenna corresponds to 8 receive beam directions, i.e. r = 8.

[0240] If m is 2, i.e. the number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 2, as shown in Figure 4 Figure 4 As shown in the 14 receive beam directions of the UE can be completed by 7 rounds of reference signal measurement.

[0241] By analogy:

[0242] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 1, m = 1, and then the UE needs to perform 8 rounds of reference signal measurement to determine the measurement results of 15 beam directions.

[0243] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 2, m = 2, and then the UE needs to perform 7 rounds of reference signal measurement to determine the measurement results of 14 beam directions.

[0244] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 3, m = 3, and then the UE needs to perform 7 rounds of reference signal measurement to determine the measurement results of 13 beam directions.

[0245] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 4, m = 4, and then the UE needs to perform 6 rounds of reference signal measurement to determine the measurement results of 12 beam directions.

[0246] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 5, m = 5, and then the UE needs to perform 6 rounds of reference signal measurement to determine the measurement results of 11 beam directions.

[0247] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 6, m = 6, and then the UE needs to perform 5 rounds of reference signal measurement to determine the measurement results of 10 beam directions.

[0248] The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 7, m = 7, and then the UE needs to perform 5 rounds of reference signal measurement to determine the measurement results of 9 beam directions.

[0249] ​The number of receive beam directions of one antenna that have an overlapping relationship with the receive beam directions of another antenna is 8, m = 8, and then the UE needs to perform 4 rounds of reference signal measurement to determine the measurement results of 8 beam directions.

[0250] In a possible implementation, the coverage factor can be the number of overlapping receive beam directions of J antennas. The network device can determine the number n of rounds of reference signal measurement performed by the UE in I receive beam directions according to the coverage factor. The network device can determine the number n in a similar manner to the UE, and details are not described herein.

[0251] As shown in FIG. 7, the embodiment of the present disclosure provides an information transmission method, wherein the method is performed by a network device and includes the following steps: Figure 7

[0252] Step 701: determining a beam sweeping coefficient N according to the capability information.

[0253] Step 702: determining a measurement duration of reference signal measurement performed by the UE in the I receive beam directions according to the beam sweeping coefficient N.

[0254] The network device determines the number n of rounds of reference signal measurement performed by the UE in I receive beam directions according to the received capability information.

[0255] The network device can determine the beam sweeping coefficient N according to the number n.

[0256] The beam sweeping coefficient N can be used to calculate the measurement duration.

[0257] In a possible implementation, the number n is positively correlated with the beam sweeping coefficient N.

[0258] In an embodiment, the beam sweeping coefficient N is equal to the number n.

[0259] In a possible implementation, the beam sweeping coefficient N can be a calculation parameter in a calculation rule used to calculate the measurement duration.

[0260] In a possible implementation, the beam sweeping coefficient N is positively correlated with the measurement duration.

[0261] The network device can calculate the measurement duration based on the beam sweeping coefficient N.

[0262] In an embodiment, the beam sweeping coefficient N is equal to the number n.

[0263] ​The network device determines the number of rounds n of reference signal measurement to be performed through the capability information, determines the beam sweeping coefficient N according to the number of rounds n, and further determines the measurement duration, thereby improving the matching degree of the measurement duration and the reference signal measurement performed by the UE, and improving the accuracy of resource configuration.

[0264] As shown in Figure 8 The embodiment of the present disclosure provides an information transmission method, wherein the method is performed by a network device, and includes the following steps:

[0265] Step 801: sending a measurement configuration to the UE, wherein the measurement configuration at least includes the measurement duration.

[0266] The network device can indicate the measurement configuration to the UE, so that the UE determines the measurement time domain resource, such as the measurement duration, for performing the reference signal measurement.

[0267] In one possible implementation, the network device can send the reference signal within the measurement duration, so that the UE performs the measurement within the I receiving beam directions within the measurement duration.

[0268] For example, after receiving the coverage factor of the receiving beam reported by the terminal, the network device configures the beam sweeping coefficient N associated with the measurement duration of the L1-RSRP of the SSB based on the SSB, and the beam sweeping coefficient N is equal to the coverage factor of the receiving beam.

[0269] The UE performs the measurement of the L1-RSRP of the SSB based on the measurement duration indicated by the network device, and reports the measurement result. After obtaining the corresponding measurement result of the L1-RSRP, the network device can select the best beam for subsequent transmission scheduling.

[0270] The following provides a specific example in combination with any of the above embodiments:

[0271] The terminal reports the coverage factor of the antenna configuration, and the network device schedules the transmission and measurement of the terminal according to the corresponding capability.

[0272] Embodiment 1

[0273] The terminal reports the coverage factor of the receiving beam of the antenna configuration according to the capability of the terminal.

[0274] The value of the coverage factor of the receiving beam is [4, 5, 6, 7, 8], which respectively corresponds to 4 to 8 times of the SSB measurement time of the terminal.

[0275] The default coverage factor of the receiving beam is 8, that is, the terminal needs to complete 8 times of SSB measurement to complete the measurement of the L1-RSRP based on the SSB.

[0276] When Beamoverlapscalingfactor=4, the two antenna panels of the terminal are fully covered, and the terminal can complete the L1-RSRP measurement of the entire received beam based on SSB in only 4 SSB measurements.

[0277] Example 2:

[0278] After receiving the coverage factor of the received beam reported by the terminal, the network configures the beam scanning factor N = Beamoverlapscalingfactor for the L1-RSRP measurement time based on SSB. Before completing the L1-RSRP measurement reporting, the network cannot obtain the terminal's L1-RSRP measurement results. Only after obtaining the corresponding L1-RSRP measurement results can the network select the optimal beam for subsequent transmission scheduling.

[0279] like Figure 9 As shown, this disclosure provides an information transmission device 100, which is disposed within a user equipment (UE) and includes:

[0280] The transceiver module 110 is configured to transmit capability information, wherein the capability information is used by the network device to determine the number n rounds n of reference signal measurements performed by the UE in I receiving beam directions, wherein one round of the reference signal measurement includes the measurement of the reference signal by J antennas in X receiving beam directions, wherein the J antennas cover the I receiving beam directions, 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.

[0281] In one embodiment, the capability information includes: a coverage factor of the received beam, used to indicate the round number n.

[0282] In one embodiment, when J = 2, and each antenna is associated with r receive beam directions, the number of rounds n is expressed by the following expression:

[0290] In one embodiment, the UE includes J of the antennas.

[0291] In one embodiment, the J antennas of the UE collectively cover I receiving beam directions.

[0292] In one embodiment, the J antennas of the UE can simultaneously perform reference signal measurements in X receiving beam directions.

[0293] like Figure 10 As shown, this disclosure provides an information transmission device 200, which is disposed within a network device and includes:

[0294] The transceiver module 210 is configured to receive capability information, wherein the capability information is used to determine the number n rounds n of reference signal measurements performed by the user equipment UE in I receiving beam directions, wherein one round of the reference signal measurement includes the measurement of the reference signal by J antennas in X receiving beam directions, wherein the J antennas cover the I receiving beam directions, 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.

[0295] In one embodiment, the capability information includes: a coverage factor of the received beam, used to indicate the round number n.

[0296] In one embodiment, when J = 2, and each antenna is associated with r receive beam directions, the number of rounds n is expressed by the following expression:

[0297] n = r - Floor(m / 2)

[0298] Where n represents the number of rounds of the reference signal measurement, m represents the number of overlapping receiving beam directions of the J antennas, and Floor() represents rounding down.

[0299] In one embodiment, the apparatus further includes:

[0300] The processing module 220 is configured to determine a beam sweeping coefficient N according to the capability information.

[0301] The processing module is further configured to determine a measurement duration of measurement of the reference signal in the I receive beam directions by the UE according to the beam sweeping coefficient N.

[0302] In one embodiment, the beam sweeping coefficient N is equal to the number of rounds n.
