Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and in particular to a beam management method and device, a storage medium, a terminal and a network side device. BACKGROUND

[0002] The terahertz wave band generally refers to geomagnetic waves in the range of 0.1-10 terahertz (THz), which is a frequency band for the transition from macroscopic electronics to microscopic photonics. The terahertz wave band has the characteristics of both microwave millimeter wave and infrared visible light, and also has some complementary characteristics to the two bands. Among them, compared with microwave millimeter wave, the terahertz electromagnetic wave has a shorter wavelength and higher detection accuracy; compared with infrared visible light, the terahertz photon has lower energy and higher energy efficiency, and better penetration. Because the terahertz electromagnetic wave has a wide frequency range, unique photon energy and propagation characteristics, and interacts with matter to exhibit rich physical connotations, it can be applied in many fields, such as high-speed communication, high-resolution radar, deep space exploration, life and environment monitoring, space remote sensing, and atmospheric monitoring.

[0003] Because the frequency point of the terahertz band is very high and the fading is large, a very fine beam is generally used to make the energy converge in a certain direction, thereby improving the coverage and reception performance. The analog beam is generated by adjusting the parameters on the phase shifter, thereby generating beams of different directions and coverage ranges. However, the parameters of the phase shifter are currently mainly designed for the center frequency point of a carrier, and when the bandwidth is large, the beam direction at the edge frequency point may be offset from the beam direction at the center frequency point. This phenomenon is more obvious when the bandwidth is larger, and can be a beam splitting phenomenon. It is generally believed that this beam splitting phenomenon is not conducive to communication transmission, because the energy on a carrier cannot be concentrated to a certain specific direction.

[0004] However, at the same time, this beam splitting characteristic can also bring some benefits to beam management, such as being able to realize multiple direction beams in the frequency domain through the same phase adjustment. In the prior art, there is no mechanism for utilizing this beam splitting characteristic to realize beam management, which brings difficulties to utilizing the split beams. SUMMARY

[0052] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 are simulation results of beam splitting in the prior art, where the horizontal axis is the beam direction, and the vertical axis is the beam power. Figure 1 The simulation scenario given is a simulation diagram of a transmission beam with a center frequency of 100 GHz, a bandwidth of 100 MHz, and 128 subcarriers, and the transmission beam is represented by a waveform corresponding to 101. Figure 2 The simulation scenario given is a simulation diagram of a transmission beam with a center frequency of 100 GHz, a bandwidth of 5 GHz, and 128 subcarriers, and the beams generated after splitting of the transmission beam are represented by waveforms corresponding to 201, 202, and 203. Figure 1 and Figure 2 The beam radiation patterns corresponding to subcarrier indexes 1, 64, and 128 are selected, respectively. It can be seen that when the bandwidth is 100 MHz, the radiation patterns corresponding to the three subcarriers almost overlap, but when the bandwidth is 5 GHz, there is a clear separation.

[0053] Based on the above beam splitting, as described in the background, there is no mechanism in the prior art to utilize this beam splitting characteristic to implement beam management, which brings difficulties to the use of the split beams.

[0054] To solve the above problems, an embodiment of the present application provides a beam management method, which comprises: determining a plurality of target frequency bands contained in a configuration measurement bandwidth, and obtaining measurement results of each target frequency band; obtaining beam management information according to part or all of the target frequency bands and their measurement results, the beam management information being used to indicate the frequency positions and / or beam qualities of the plurality of target frequency bands after beam splitting; and reporting the beam management information to a network, so that the network determines the plurality of target frequency bands contained in the configuration measurement bandwidth according to the beam management information. Thus, the beam management can be realized by utilizing the beam splitting characteristic.

[0055] Please refer to Figure 3 The first beam management method provided by the embodiments of the present application, Figure 3 The method can be performed by a terminal device (or User Equipment, UE for short) accessing a network, and the terminal device can include a mobile phone, a computer, etc. The following embodiments take the UE as an example to introduce the beam management method, which specifically includes the following steps:

[0056] Step S301, determining a plurality of target frequency bands contained in a configured measurement bandwidth, and obtaining a measurement result of each target frequency band;

[0057] The configured measurement bandwidth is a bandwidth corresponding to a beam, which is configured by the network. Please refer to Figure 4 , Figure 4 A schematic diagram of beam splitting provided by the embodiments of the present application is shown in the figure. When a beam is transmitted, the phase shifter designs the center frequency point and the corresponding bandwidth of the original transmitted beam. When the bandwidth is large, the beam direction on the edge frequency point may be deviated from the beam direction of the center frequency point, and beam splitting may occur. The center frequency point of the original transmitted beam is shown in Figure 4 The configured measurement bandwidth of the original transmitted beam M is shown in the figure as a frequency band M. For the configured measurement bandwidth M of the original transmitted beam, a Channel State Information-Resource Indicator (CSI-RS) resource is configured on this bandwidth M. In the scenario of beam splitting, this CSI-RS resource may correspond to different transmitted beams at different frequency bands. That is, the original transmitted beam M generates beams 1, 2, 3 and 4 after beam splitting, and the frequency ranges corresponding to each split beam are shown in the figure as frequency bands m1, m2, m3 and m4. The UE itself measures the beam quality of the configured measurement bandwidth, and determines the frequency bandwidth corresponding to the plurality of split beams contained in the configured measurement bandwidth, i.e. the target frequency band, according to the measurement result.

[0058] Optionally, the UE divides the configured measurement bandwidth into a plurality of measurement frequency bands according to a preset division rule, and measures the signal quality of each measurement frequency band, such as measuring the Reference Signal Receiving Power (RSRP) of each frequency band. The preset division rule can be set by the UE according to the needs, or can be indicated by the network side. Optionally, the preset division rule is set according to the resource blocks (RBs) or subcarriers contained in the configured measurement bandwidth, for example, one or more RBs or subcarriers corresponding to a frequency band are taken as a measurement frequency band.

[0059] Optionally, the UE determines whether to perform the measurement according to the frequency range of the beam. Figure 3 The method, for example, when the frequency range of a certain beam is in the range of 0.1-10 THz, the frequency range of the beam is configured as the measurement bandwidth and the measurement is performed. Figure 3 The method.

[0060] In step S302, beam management information is obtained according to part or all of the target frequency ranges and the measurement results thereof, and the beam management information is used to indicate the frequency positions of the multiple target frequency ranges after beam splitting and / or the beam quality.

[0061] In step S303, the beam management information is reported to the network, so that the network determines the multiple target frequency ranges contained in the configured measurement bandwidth according to the beam management information.

[0062] After the UE determines the multiple frequency bandwidths (i.e., target frequency ranges) corresponding to the multiple split beams contained in the configured measurement bandwidth according to the foregoing detection, at least one or several of the multiple target frequency ranges and the corresponding measurement results are reported to the network side, so that the network side determines the beams generated after beam splitting and the beam signal quality of each beam.

[0063] Optionally, the UE sends the beam management information to the network side through uplink control information (UCI) or a media access layer control element (MAC CE), which has better real-time performance, or the UE sends the beam management information to the network side through radio resource control (RRC) signaling.

[0064] Optionally, the beam management information obtained according to part or all of the target frequency ranges and the measurement results thereof in step S302 includes: selecting a number of target frequency ranges with the best quality from the multiple target frequency ranges contained in the configured measurement bandwidth, and obtaining the beam management information according to the selected target frequency ranges and the measurement results thereof.

[0065] In order to save the overhead of the UE reporting the beam management information, the UE only reports one or more target frequency ranges with the best signal quality in the configured measurement bandwidth and the measurement results thereof to the network.

[0066] By Figure 3The method, UE detects the split beams and beam signal quality based on the characteristics of the beam splitting phenomenon, and returns the detection results to the network side, so as to realize the information alignment between the UE and the network side. Therefore, the beam management can be performed based on the characteristics of the beam splitting. The network or UE side can introduce some implementation operations and actions that affect the standard, such as the network side device can transmit information to the UE through multiple beam directions generated by beam splitting when scheduling communication, so as to change the beam splitting phenomenon into a treasure, and better improve the efficiency of the communication system.

[0067] In one embodiment, referring to Figure 3 and Figure 5 , Figure 5 for Figure 3 The flowchart of one specific embodiment of step S301 in

[0068] Step S3011, measuring each RB or subcarrier corresponding to the configuration measurement bandwidth to obtain a plurality of measurement results;

[0069] The UE takes each RB or subcarrier corresponding frequency segment as the divided measurement frequency segment, and measures each measurement frequency segment to obtain the measurement result corresponding to the frequency segment corresponding to each RB or subcarrier. In this step, the UE measures the frequency segment corresponding to each RB or subcarrier, which can refer to RSRP measurement or beam arrival angle measurement.

[0070] Step S3012, when the difference between the measurement results of a plurality of RBs or subcarriers is less than a preset value, merging the plurality of RBs or subcarriers;

[0071] Step S3013, taking the frequency segment corresponding to the merged plurality of RBs or subcarriers as a single target frequency segment;

[0072] Step S3014, obtaining the measurement result of a single target frequency segment according to the measurement results of a plurality of RBs or subcarriers contained in each target frequency segment.

[0073] The frequency segments of the RBs or subcarriers with the same or similar measurement results are merged, and further, the frequency difference between the merged frequency segments is less than a frequency threshold, that is, the frequency segments of the RBs or subcarriers with the same or similar measurement results and similar frequency positions are merged as a target frequency segment. Optionally, the UE merges the frequency segments corresponding to a plurality of RBs or subcarriers with the same or similar beam arrival angles into a target frequency segment. The measurement result of the target frequency segment is obtained according to the measurement results of the merged RBs or subcarriers.

[0074] Optionally, the measurement result of each target frequency segment is obtained according to the measurement results of the plurality of RBs or subcarriers contained in each target frequency segment, including: averaging the measurement results of the plurality of RBs or subcarriers contained in each target frequency segment, and taking the average value as the measurement result of each target frequency segment.

[0075] If the UE has measured the signal quality (such as RSRP) of the N RBs or subcarriers before step S3014, when the N RBs are combined as a target frequency segment, the measurement result of the target frequency segment can be the average value of the measurement results of the N RBs.

[0076] Or, if the UE has not measured the signal quality (such as RSRP) of the N RBs or subcarriers before step S3014, the UE performs signal quality measurement (such as RSRP measurement) on each target frequency segment to obtain the measurement result of the target frequency segment.

[0077] It should be noted that the measurement result of each target frequency segment is determined in other ways, for example, the median of the measurement results of the plurality of RBs or subcarriers contained in each target frequency segment is taken as the measurement result of the target frequency segment, and the like, which will not be described here.

[0078] In this embodiment, the UE can use RBs or subcarriers as the granularity of dividing the measurement frequency segment, and determine which RBs or subcarriers are contained in each target frequency segment after beam splitting according to the measurement, so as to determine the plurality of beams after splitting. Thus, the beam splitting situation can be obtained based on the detection of the beams at the UE side.

[0079] According to the distribution of the target frequency segments corresponding to each beam after beam splitting, the UE or the network side determines the frequency positions of each target frequency segment, which can include the following three scenarios:

[0080] Scenario one: if the frequency lengths of each target frequency segment are similar, the frequency positions of each target frequency segment contained in the configured measurement bandwidth are determined by the start frequency position of the configured measurement bandwidth and the number of target frequency segments.

[0081] When the frequency lengths of the plurality of target frequency segments contained in the configured measurement bandwidth are similar, the UE or the network side can determine the frequency positions of each target frequency segment contained in the configured measurement bandwidth through the start frequency position (start-position(M)) of the configured measurement bandwidth and the number of target frequency segments. The frequency positions of the configured measurement bandwidth (including the start frequency position start-position(M) and the end frequency position) are generally determined by the network.

[0082] Please refer to Figure 6 , Figure 6Fig. 1 is a distribution diagram of target frequency segments in a scenario one of an embodiment of the present application; original transmitting beam M generates four beams (beam 1, beam 2, beam 3 and beam 4) after beam splitting, the starting frequency position of the original transmitting beam M (i.e. the starting frequency position of the configured measurement bandwidth) is denoted as start-position (M), and the number of target frequency segments is 4.

[0083] Fig. 2 is a distribution diagram of target frequency segments in a scenario two of an embodiment of the present application; original transmitting beam M generates four beams (beam 1, beam 2, beam 3 and beam 4) after beam splitting, the starting frequency position of the original transmitting beam M (i.e. the starting frequency position of the configured measurement bandwidth) is denoted as start-position (M), and the number of target frequency segments is 4.

Figure 7 Figure 7 Fig. 4 is a distribution diagram of target frequency segments in a scenario four of an embodiment of the present application; original transmitting beam M generates four beams (beam 1, beam 2, beam 3 and beam 4) after beam splitting, the starting frequency position of the original transmitting beam M (i.e. the starting frequency position of the configured measurement bandwidth) is denoted as start-position (M), and the number of target frequency segments is 4.

[0085] Fig. 5 is a distribution diagram of target frequency segments in a scenario five of an embodiment of the present application; original transmitting beam M generates four beams (beam 1, beam 2, beam 3 and beam 4) after beam splitting, the starting frequency position of the original transmitting beam M (i.e. the starting frequency position of the configured measurement bandwidth) is denoted as start-position (M), and the number of target frequency segments is 4.

[0086] Fig. 6 is a distribution diagram of target frequency segments in a scenario six of an embodiment of the present application; original transmitting beam M generates four beams (beam 1, beam 2, beam 3 and beam 4) after beam splitting, the starting frequency position of the original transmitting beam M (i.e. the starting frequency position of the configured measurement bandwidth) is denoted as start-position (M), and the number of target frequency segments is 4. Figure 8 Figure 8 Fig. 7 is a distribution diagram of target frequency segments in a scenario seven of an embodiment of the present application; original transmitting beam M generates four beams (beam 1, beam 2, beam 3 and beam 4) after beam splitting, the starting frequency position of the original transmitting beam M (i.e. the starting frequency position of the configured measurement bandwidth) is denoted as start-position (M), and the number of target frequency segments is 4.

[0087] In one embodiment, the reporting of the beam management information to the network comprises: reporting at least one of the following information to the network: the number of target frequency segments contained in the configured measurement bandwidth, the index number of each target frequency segment, the determined frequency position corresponding to each target frequency segment, and the measurement result of each target frequency segment. ​​

[0088] When the UE reports the beam management information to the network, each target frequency segment and its measurement result can be indicated to the network in an explicit or implicit manner.

[0089] The manner in which the beam management information indicates all target frequency segments contained in the configuration measurement bandwidth can include: manner 1, for each target frequency segment, the beam management information indicates the frequency length of the target frequency segment; manner 2, for the distribution of target frequency segments, the beam management information indicates the number of all target frequency segments contained in the configuration measurement bandwidth, and the network side device determines the frequency position of each target frequency segment according to the frequency position of the configuration measurement bandwidth and the number of target frequency segments; manner 3, for the distribution of target frequency segments, the beam management information indicates the starting frequency position and the frequency length of each target frequency segment contained in the configuration measurement bandwidth, or indicates the starting frequency position and the ending frequency position of each target frequency segment contained in the configuration measurement bandwidth, so that the network side device determines the frequency position corresponding to each target frequency segment. Figure 6 For the distribution of target frequency segments, the beam management information can only indicate the number of all target frequency segments contained in the configuration measurement bandwidth, and the network side device can determine the frequency position of each target frequency segment according to the frequency position of the configuration measurement bandwidth and the number of target frequency segments. Figure 7 For the distribution of target frequency segments, the beam management information can indicate the number of all target frequency segments contained in the configuration measurement bandwidth and the frequency length of each target frequency segment; the network side device determines the frequency position of each target frequency segment according to the frequency position of the configuration measurement bandwidth, the number of target frequency segments and the frequency length of each target frequency segment. Figure 8 For the distribution of target frequency segments, the beam management information can indicate the starting frequency position and the frequency length of each target frequency segment contained in the configuration measurement bandwidth, or indicate the starting frequency position and the ending frequency position of each target frequency segment contained in the configuration measurement bandwidth, so that the network side device determines the frequency position corresponding to each target frequency segment. Manner 3 can also be used to indicate part of the target frequency segments contained in the configuration measurement bandwidth.

[0090] Optionally, each target frequency segment can be represented by an index number, and the measurement result of each target frequency segment corresponds to the index number. Alternatively, the index number can not be reported, but the order of the frequency position of each target frequency segment in the configuration measurement bandwidth is used to implicitly indicate.

[0091] Optionally, the UE can report the measurement result of each target frequency segment to the network in a differential feedback manner, that is, only the measurement result of one target frequency segment is directly fed back, and the measurement result of the other target frequency segment is represented by the difference of the directly fed-back measurement result. In this way, the signaling overhead of the beam management information can be further saved.

[0092] Please refer to Figure 9 , Figure 9 The flowchart of the second beam management method of the embodiment of the present application is shown in FIG. 2, and the method comprises the following steps:
