Description

[0001] This application is a divisional application, the original application has the application number of 202080001800.9, the application date is July 31, 2020, and the invention name is "a beam management method, a beam management device and a storage medium". TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of communication, and particularly relates to a beam management method, a beam management device and a storage medium. BACKGROUND

[0003] In the related art, in the new radio (NR) Rel-16, positioning measurement for terminals in a connected state is discussed, and positioning purpose reference signals are defined, including downlink positioning reference signals (PRS) and uplink sounding reference signals (SRS) for positioning. For positioning, the line of sight (LOS) path is very important, and the measurement value of the LOS path can effectively improve the positioning accuracy. No matter whether the signal strength value, time value or angle value is measured, the LOS path measurement is required to achieve the highest positioning accuracy. However, in fact, the LOS path is not necessarily available. Therefore, in the positioning discussion of Rel-16, it is hoped that the first arrival path, that is, the earliest arrival path, can be found as much as possible.

[0004] In the related art, in order to find the first arrival path, a large number of positioning purpose reference signals need to be sent for positioning measurement.

[0076] The example embodiments will be described in detail with reference to the drawings, of which examples are shown. The following description is made in connection with the drawings, where like reference numerals designate similar or identical elements in the different figures. The implementations described in the following example embodiments are not meant to represent all implementations consistent with the present disclosure. Rather, they are merely examples that are consistent with some aspects of the present disclosure as detailed in the appended claims.

[0077] In the related art, a terminal communicates with a wireless network device such as a radio access device, a core network device, and the like based on a cellular network, and can implement a positioning measurement function. For example, in NR Rel-16, positioning measurement for a terminal in a connected state is mainly discussed, and a reference signal for positioning is defined. The reference signal for positioning can include, for example, a PRS for downlink positioning and an SRS for uplink positioning. The positioning measurement includes terminal measurement and wireless network device measurement, and the measurement values include signal strength measurement values, signal transmission time values, and channel arrival or departure angle values.

[0078] In the related art, the measurement value of the LOS path can effectively improve the positioning accuracy, so when measuring the signal strength value, the time value, or the angle value, it is necessary to measure the LOS path to achieve the highest positioning accuracy. However, in fact, the LOS path does not always exist. The first arrival path is closest to the LOS path or is the LOS. Therefore, in the positioning discussion of Rel-16, it is desirable to determine the first arrival path, also known as the first arrival path, as much as possible.

[0079] In the related art, in order to determine the first arriving path, a large number of positioning reference signals need to be sent. For example, a base station needs to send positioning reference signals using each transmission beam (Tx beam), and for each positioning reference signal sent by each base station Tx beam, the terminal needs to receive the positioning reference information sent by the Tx beam using each reception beam (Rx beam) of the terminal, so as to finally obtain the first arriving path. Therefore, in the worst case, the number of reference signals required for first arriving path determination is the product of the number of Tx beams of the base station and the number of Rx beams of the terminal. In the uplink, in the worst case, the number of reference signals required for first arriving path determination is the product of the number of Tx beams of the terminal and the number of Rx beams of the base station. However, the more reference signals that need to be measured, the more power the terminal consumes, the longer the positioning measurement needs to take, and the greater the positioning delay and the lower the positioning accuracy.

[0080] In order to reduce the power consumption of the terminal in obtaining the first arriving path, the Tx beam and the Rx beam corresponding to the first arriving path can be determined in the beam management in the early stage, so that the number of reference signals to be measured can be reduced when the measurement is performed. However, in the beam management measurement in Rel-16, only the measurement of the signal strength of the beam is included, and the signal strength includes Layer 1-Reference Signal Received Power (L1-RSRP) / Layer 1-Received Signal Strength Indication (L1-RSSI). The measurement report includes the reference signal ID and the L1-RSRP / L1-RSSI.

[0081] In the related art, the first arriving path can be determined based on the first arriving path information (such as signal flight time). However, the existing beam management measurement and reporting do not include the flight time of the signal on each path, so the first arriving path cannot be found in advance for the transmission of positioning reference signals, resulting in the need to send and measure a large number of positioning reference signals to find the first arriving path, thereby increasing the power consumption of the terminal, prolonging the positioning measurement time, and reducing the positioning accuracy.

[0082] Therefore, the embodiments of the present disclosure provide a beam management method, which includes the first arriving path information of the beam corresponding to the reference signal in the measurement result of the reference signal measurement and feedback in the beam management process, and subsequently determines the first arriving path based on the first arriving path information, so as to facilitate the determination of the first arriving path as soon as possible, reduce the power consumption of the terminal, and reduce the positioning delay and improve the positioning accuracy.

[0083] In an example, the first-arrival-path information indicates whether the corresponding beam of the reference signal is the first-arrival-path, or the first-arrival-path information includes time-of-flight information of the reference signal.

[0084] In another example, in the process of beam management, when performing the reference signal measurement, not only the signal strength of the feedback reference signal is measured, but also the time-of-flight of the feedback reference signal is measured. Thus, the base station can configure the reference signal for positioning measurement according to the signal strength and the time-of-flight, such as configuring the positioning reference signal with shorter time-of-flight as much as possible. Thus, the terminal can find the first-arrival-path as soon as possible when performing the positioning measurement, reduce the energy consumption of the terminal, and also reduce the positioning delay and improve the positioning accuracy.

[0085] The beam measurement method provided by the embodiments of the present disclosure can be applied between devices that perform beam management and reference signal transmission interaction. For example, it can be between a network device such as a base station and a terminal. For the convenience of description, the device that performs reference signal reception and measurement and feeds back the measurement result is referred to as a first device, for example, a terminal, and the device that transmits the reference signal and performs reference signal configuration is referred to as a second device, for example, a network device such as a base station.

The terminal can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., which is a device that provides voice and / or data connectivity for a user, for example, a terminal can be a handheld device with wireless connection function, a vehicle-mounted device, an Internet of Things (IoT) device, an Industrial Internet of Things (IIoT) device, etc. At present, some examples of terminals are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the first device can also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form of the first device.

[0087] In the embodiments of the present disclosure, the second device includes a wireless network device that communicates based on a cellular network, for example, can include a wireless access network device such as a base station, or can include a core network device such as a location management function entity (LMF). Further, the wireless access network device involved in the present disclosure can be a base station, an evolved node B (base station), a home base station, an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), or a transmission and reception point (TRP), etc., and can also be a gNB in an NR system, or can also be a component or a part of a device that constitutes a base station, etc. When it is a direct communication (D2D) or a vehicle-to-everything (V2X) communication system, the second device can also be a terminal, for example, a vehicle-mounted device.

[0088] In the embodiments of the present disclosure, the second device can also be a wireless local area network device that communicates based on a WLAN, can also be a Bluetooth device that communicates based on Bluetooth, and can also be an Ultra Wide Band (UWB) device that communicates based on UWB. It can be understood that the second type of positioning node can also be a sensor that communicates based on one or more wireless communication technologies of WLAN, Bluetooth, and UWB. It should be understood that the specific technology and specific device form of the second device are not limited in the embodiments of the present disclosure.

[0089] Figure 1 is a flowchart of a beam management method according to an example embodiment, as shown in Figure 1 The beam management method is used in the first device, and includes the following steps.

[0090] In step S11, reference signal configuration information is received.

[0091] In step S12, the reference signal is measured based on the reference signal configuration information, and the measurement result is fed back, and the measurement result includes first arrival path information of the reference signal corresponding beam.

[0092] In the embodiments of the present disclosure, the reference signal configuration information can be sent by the second device and received by the first device.

[0093] Figure 2 is a flowchart of a beam management method according to an example embodiment, as shown in Figure 2 The beam management method is used in the second device, and includes the following steps.

[0094] In step S21, the reference signal configuration information is sent.

[0095] In step S22, the first device measures the reference signal based on the reference signal configuration information and feeds back the measurement result, which includes the first arrival path information of the beam corresponding to the reference signal.

[0096] In the embodiments of the present disclosure, the second device sends the reference signal configuration information, the first device measures the reference signal based on the reference signal configuration information and feeds back the measurement result, which includes the first arrival path information of the beam corresponding to the reference signal. The second device receives the measurement result fed back by the first device based on the reference signal configuration information, which includes the first arrival path information of the beam corresponding to the reference signal, and can subsequently configure the reference signal for positioning measurement according to the first arrival path information, such as configuring the positioning reference signal with the shortest time of flight. Thus, the first device can find the first arrival path as soon as possible in the positioning measurement process, reduce the energy consumption of the terminal, and also reduce the positioning delay and improve the positioning accuracy.

[0097] The beam management method involved in the embodiments of the present disclosure is described below in combination with actual applications.

[0098] In an implementation, the reference signal configuration information sent by the second device (the reference signal configuration information received by the first device) can include, for example, reference signal identification (ID), time domain position, frequency domain position, etc., and can also include the purpose of the reference signal (such as for beam management) and whether repetition is on or off. Wherein, repetition on means that the second device repeatedly sends multiple reference signals with the same Tx beam, that is, the Tx beams of the multiple reference signals are the same. In this case, the first device can use its own different Rx beam to receive the multiple reference signals and find out its best Rx beam. Repetition off means that the second device sends multiple reference signals with different Tx beams, that is, the Tx beams of the multiple reference signals are different. The reference signal configuration information can also include the Transmission Reception Point (TRP) ID or cell ID corresponding to the reference signal, and the cell ID can be the serving cell ID or the neighboring cell ID of the first device. The reference signal identification can be the Synchronization Signal Block (SSB) identification, the Channel-state information RS (CSI-RS) identification, the PRS identification or the SRS identification.

[0099] The first device in the embodiments of the present disclosure receives reference signal configuration information to measure the beams corresponding to the reference signals.

[0100] The measurement of the beams corresponding to the reference signals by the first device in the embodiments of the present disclosure includes determining first arrival path information corresponding to the beams.

[0101] The first arrival path information in the embodiments of the present disclosure can represent whether the beam corresponding to the reference signal is the first arrival path. For example, the first arrival path information represents that the beam corresponding to the reference signal is the first arrival path, or the first arrival path information represents that the beam corresponding to the reference signal is not the first arrival path. In an example, the first arrival path information can be represented as yes or no, that is, whether the beam corresponding to the reference signal is the first arrival path, and the feedback information is indicated as yes or no.

[0102] The first arrival path information in the embodiments of the present disclosure can include time of flight information of the reference signal.

[0103] In an embodiment, the measurement of the reference signals in the embodiments of the present disclosure can include measuring the time of flight of each reference signal.

[0104] In the embodiments of the present disclosure, the time of flight information includes ordering information of multiple arrival paths in order of time of flight. In an example, the first arrival path information is represented as the ordering of the time of flight from small to large. The shortest time of flight is the first arrival path (for example, 2 bits, such as 00), the second shortest is the second arrival path (such as 01), the third shortest is the third arrival path (such as 11), and so on to represent multiple ordered arrival paths.

[0105] In the embodiments of the present disclosure, the time of flight information includes a time of flight value, that is, the first arrival path information is represented as a time of flight value. In an embodiment, the time of flight value includes an absolute value of the time of flight, and / or a relative value of the time of flight relative to the absolute value of the time of flight. In an example, the absolute value of the time of flight corresponds to the reference signal with the shortest time of flight. For example, the first arrival path information corresponding to the shortest time of flight value is indicated as the absolute value of the shortest time of flight, and the first arrival path information corresponding to other time of flight values is indicated as the relative value relative to the absolute value of the shortest time of flight. In another embodiment, the time of flight value includes a specified value, and / or a relative value relative to the specified value. In an example, the specified value corresponds to the reference signal with the shortest time of flight. For example, the first arrival path information corresponding to the shortest time of flight value is indicated as 0, and the first arrival path information corresponding to other time of flight values is indicated as the relative value relative to 0.

[0106] In an embodiment, the measurement of the beams corresponding to the reference signals in the embodiments of the present disclosure includes measuring the signal strength of each reference signal.

[0107] In an implementation, the first device measures the signal strength and the time of flight of each reference signal, and the first device stores a one-to-one correspondence between the reference signal identifier, the receiving beam, the signal strength value, and the time of flight, and the like. In an example, the correspondence between the reference signal identifier, the receiving beam, the signal strength value, and the time of flight can be shown in Table 1 as follows.

[0108] Table 1

[0109]

[0110] In the embodiments of the present disclosure, the measurement result fed back by the first device can further include a reference signal identifier. The reference signal identifier can be a synchronization signal block (SSB) identifier, a channel-state information RS (CSI-RS) identifier, or a PRS identifier or an SRS identifier.

[0111] Further, in the embodiments of the present disclosure, the measurement result fed back by the first device can further include a transmission reception point (TRP) identifier and / or a cell identifier. The cell identifier can be a serving cell identifier or a neighbor cell identifier.

[0112] In the embodiments of the present disclosure, the first device feeds back a correspondence between the reference signal identifier and the first arriving path information. Alternatively, the first device feeds back a correspondence between the reference signal identifier and the time of flight information of the reference signal.

[0113] Further, the reference signal identifier can also have a correspondence with the signal strength.

[0114] In the embodiments of the present disclosure, the first device can feed back a set number of reference signal identifiers with the strongest signal strength, and / or feed back a set number of reference signal identifiers with the shortest time of flight.

[0115] In an example, the first device feeds back N (N is a natural number, for example, N is 1, 2, or 4) reference signal identifiers with the strongest signal strength and the signal strength values. When N is 1, the measurement result fed back includes the identifier of the reference signal with the strongest signal strength and the corresponding signal strength value, which can be the absolute value of the signal strength value corresponding to the reference signal with the strongest signal strength. When N is greater than 1, the measurement result fed back includes the identifier of the reference signal with the strongest signal strength and the absolute value of the corresponding signal strength value, and the signal strength relative value of other signal strength values relative to the absolute value of the signal strength value with the strongest signal strength.

[0116] In the embodiments of the present disclosure, the measurement result fed back by the first device further comprises a time of flight. The reference signal identifier included in the measurement result is determined based on the signal strength value and / or the time of flight. It can also be understood that there is a corresponding relationship between the signal strength value, the time of flight and the reference signal identifier.

[0117] In an implementation, the reference signal identifier corresponds to the reference signal with the strongest signal strength value obtained by measurement, that is, the measurement result can comprise the reference signal identifier, the signal strength value and the time of flight value of the N reference signals with the strongest signal strength. In another implementation, the reference signal identifier corresponds to one or more reference signals with the shortest time of flight obtained by measurement, that is, the measurement result can comprise the reference signal identifier, the signal strength value and the time of flight value of the N reference signals with the shortest time of flight. In yet another implementation, the reference signal identifier corresponds to one or more reference signals with the largest weighted sum between the signal strength value and the time of flight obtained by measurement. That is, the signal strength and the time of flight are multiplied by a weighted value to obtain a weighted sum, and the reference signal identifier, the signal strength value and the time of flight value of the N reference signals with the largest weighted sum are fed back.

[0118] It can be understood that the value of N in the embodiments of the present disclosure is a positive integer greater than or equal to 1.

[0119] In the embodiments of the present disclosure, for each reference signal and the Rx beam of the first device, one or more arrival paths can be measured. If the first device can distinguish the arrival time between multiple paths, the first device can measure multiple time of flight values.

[0120] In an implementation of the embodiments of the present disclosure, if the first arrival path information indicates that the reference signal corresponds to the first arrival path or the non-first arrival path, when the first device measures multiple paths, the first path in the multiple paths is taken as the main path. In another implementation, if the first arrival path information indicates the sorting information of the time of flight, when the first device measures multiple paths, the first path in the multiple paths is taken as the main path. In yet another implementation, if the first arrival path information indicates the time of flight value, the first device can feed back the time of flight value and the signal strength value of one path or multiple paths, or feed back the weighted average value of the time of flight value and the signal strength value of multiple paths.

[0121] Further, the time of flight fed back by the first device to the second device in the embodiments of the present disclosure can be a one-way time of flight, a two-way time of flight, or a one-way time of flight and a two-way time of flight.

[0122] In one implementation, the time of flight includes one-way time of flight. Assuming that the time at which the second device transmits the reference signal is T1, and the time at which the first device receives the reference signal is T2, then the time of flight is T2-T1.

[0123] There are multiple ways to define T1 in the embodiments of the present disclosure. In one way, T1 is defined based on a synchronization clock. In this case, the first device and the second device are in a synchronization system, and the synchronization clocks of the two devices are shown in FIG. 1. Figure 3 For example, when the first device is a terminal and the second device is a base station, the concept of downlink synchronization is that the base station transmits a reference signal at the start of slot #0, and the terminal receives the reference signal at the start of slot #0. In this case, the start of slot #0 at the terminal side and the start of slot #0 at the base station side are different by the transmission time of the reference signal. Therefore, if the Tx beam of the second device transmitting the reference signal and the Rx beam of the first device receiving the reference signal are the same as those at the time of downlink synchronization, then T2-T1 is 0. If they are not the same, T2-T1 can be positive or negative. Therefore, T1 is defined as the time at which the first device believes that the second device transmits the reference signal after the first device and the second device are synchronized (mainly downlink synchronization, i.e., the first device is synchronized according to the reference signal transmitted by the second device), i.e., the time displayed by the synchronization clock.

[0124] In another implementation, T1 can be defined based on an absolute clock. The time of the absolute clock at T1 of the second device (see FIG. 1) is Figure 3 The time of the absolute clock at the first device is the same as the time of the absolute clock at the second device, so the first device needs to be notified by the second device of the time of the absolute clock at T1 (the notification can be explicit, such as sending time information, or implicit, such as different reference signal IDs / frequency domains / sequences representing different times). The time of the absolute clock at the first device when receiving the reference signal is the one-way time of flight.

[0125] In yet another implementation, T1 can be another reference time, such as the time at which the first device receives a reference signal transmitted by a third device. In this case, the time at which the first device receives the reference signal transmitted by the second device is T2. In this way, T2-T1 means the time difference between the reference signal from the second device and the reference signal from the third device received by the first device.

[0126] It can be understood that in the above examples, the second device transmits the reference signal and the first device measures the time. However, in actual implementation, the first device can transmit the reference signal and the second device measures the time. If necessary, the result of measuring the time also needs to be sent to the other party.

[0127] In the embodiments of the present disclosure, T1 is defined differently, and the corresponding time of flight value has different meanings. Therefore, the time of flight value involved in the embodiments of the present disclosure can be a general time measurement value, and in some cases, the time measurement value is the time of flight, and in some cases, the time measurement value is the received time difference value.

[0128] In an implementation, the time of flight includes a two-way time of flight. For example, the time at which the second device transmits the first reference signal is T1, the time at which the first device receives the first reference signal is T2, the time at which the first device transmits the second reference signal is T3, and the time at which the second device receives the second reference signal is T4. Then, the two-way time of flight is T4-T1-(T3-T2).

[0129] It can be understood that, in the embodiments of the present disclosure, if the time of flight includes a two-way time of flight, the first device needs to send the value of T3-T2 to the second device.

[0130] It can be further understood that, in the embodiments of the present disclosure, the two-way time of flight can be measured by the first device, or measured by the second device, or measured by both. If necessary, the measurement time result also needs to be sent to the other party.

[0131] The beam management method provided by the embodiments of the present disclosure is used for positioning, mainly including beam measurement and feedback. In addition to the feedback of the reference signal ID and the signal strength, the time of flight measurement value also needs to be fed back, which is used for the second device to configure the reference signal for positioning purposes according to the time measurement value, so that the first device can find the first arrival path as soon as possible when positioning measurement, thereby reducing the positioning delay and improving the positioning accuracy.

[0132] It can be understood that the beam management method provided by the embodiments of the present disclosure can be applied to the implementation process of the interaction between the first device and the second device. For the implementation process of the interaction between the first device and the second device to realize the beam management method, reference can be made to the related description of the above embodiments, which will not be repeated here.

[0133] Based on the same concept, the embodiments of the present disclosure also provide a beam management apparatus.

In combination with the units and algorithm steps of each example disclosed in the embodiments of the present disclosure, the embodiments of the present disclosure can be realized in the form of hardware or a combination of hardware and computer software.
