technical field

The present invention relates to the field of communication technologies, and in particular, to a beam history information transmission method, a terminal and a network device.

Background technique

In the research of the fifth generation (5Generation, 5G) mobile communication system, or New Radio (New Radio, NR) system, the working frequency band supported by the system is increased to above 6 GHz, and the highest is about 100 GHz. The high frequency band has abundant idle frequency resources, which can provide greater throughput for data transmission. The coverage of high-frequency bands is limited, and multiple-input multiple-output (MIMO) technology with multiple antennas needs to be used to improve coverage and capacity.

The analog beamforming is transmitted in full bandwidth, and each polarization direction array element on the panel of each high-frequency antenna array can only transmit the analog beam in a time-division multiplexing manner. The shaping weight of the analog beam is realized by adjusting the parameters of the radio frequency front-end phase shifter and other equipment. At present, the training of analog beamforming vectors is usually carried out in a polling manner, that is, the array elements in each polarization direction of each antenna panel transmit training signals in turn at the appointed time in a time-division multiplexing manner, that is, the candidate shaping vectors. , the terminal feeds back a beam report after measurement, so that the network device can use the training signal to implement analog beam transmission when transmitting services next time. Further, the network device configures beam reporting (beam reporting) setting information (reporting setting) for the terminal through high-level signaling, including content information of beam reporting, time domain related messages of beam reporting (such as: periodic, aperiodic, semi-persistent) etc.), frequency granularity information of beam reports, etc.

In a Long Time Evolution (LTE) system, if the terminal has the ability to store historical measurement information, when the network device requests the terminal to send historical measurement information through a message, the terminal reports the stored historical measurement information through signaling , the report content mainly includes the cell ID, stay time and out of service time of the cell where it used to be, the main purpose of which is to assist the network device to track the historical location information of the terminal. In the 5G system, the concept of beams is introduced, and the terminal cannot report the historical measurement information related to the beam to the network device using the traditional historical measurement information report, which is not conducive to the determination of the historical location of the terminal and cannot achieve accurate mobility management.

Rather, these embodiments are provided so that the present invention will be more thoroughly understood, and will fully convey the scope of the present invention to those skilled in the art.

It is to be understood that the data so used may be interchanged under appropriate circumstances such that the embodiments of the application described herein can, for example, be practiced in sequences other than those illustrated or described herein.

As shown in FIG. 1 , the beam history information transmission method according to the embodiment of the present invention is applied to the terminal side, and specifically includes the following steps:

Step 11: When the reporting conditions are met, the beam history information is reported to the network device.

Here, the terminal reports the currently stored beam history information to the network device when certain reporting conditions are met. The beam history information is beam information of historical beams associated with the terminal, and is mainly used to represent the beam information of the terminal's historical movement information. Among them, it is worth pointing out that the triggering methods for the terminal to report the beam history information include active triggering and passive triggering. Specifically, meeting the reporting conditions includes: meeting preset trigger reporting conditions, or receiving a request sent by a network device to report. A request for reporting beam history information. In the following this embodiment, the reporting of the beam history information will be described in detail in combination with these two manners.

Method 1. Active reporting method

Step 11 is specifically as follows: the terminal detects whether the preset trigger reporting condition is met, and when detecting that the preset trigger reporting condition is met, reports the beam history information to the network device.

The preset trigger reporting conditions mentioned here are predefined trigger reporting conditions or trigger reporting conditions specified in the protocol. For example, when it is detected that the service beam of the terminal is switched, the service beam before the switching is recorded in the beam history information and report it to the network device, or, when it is detected that the cell to which the terminal belongs is changed, record the beam associated with the cell before the handover in the beam history information and report it to the network device. Or, after reaching a certain preset time, the current existing beam history information is reported to the network device. Specifically, the terminal can report the beam history information value at one time, or periodically report to the network device according to a preset period. Beam history information recorded by yourself.

Method 2, passive reporting method

Step 11 is specifically: when receiving a reporting request sent by the network device for requesting to report the beam history information, reporting the beam history information to the network device.

Here, it means that only when the network device configures the beam history information reporting configuration for the terminal, the terminal will detect whether the trigger condition of the reporting configuration is satisfied, and if it is satisfied, the terminal will report.

Further, it is worth noting that in the above two reporting methods, the beam history information reported by the terminal to the network device may be all beam information recorded by the terminal, or may be part of all beam information. Wherein, when reporting part of the beam information, it can be implemented by referring to the following method: reporting the beam information whose beam quality or beam number exceeds the second preset threshold in the beam history information to the network device. For example, assuming that the beam quality is divided into five levels: 1, 2, 3, 4, and 5, and the predefined second preset threshold is level 3, then when the terminal reports the beam history information to the network device, only the recorded beam information The beam information with the beam quality higher than level 3 is reported to the network device. Alternatively, assuming that the second preset threshold of the number of beams is set to 3, the terminal will report the recorded beam history information to the network device when recording 3 or more historical beams.

Further, the above-mentioned beam history information includes at least one of the following information:

The frequency point information of the cell global identifier (Cell Global Identifier, CGI) or the physical cell identifier (Physical Cell Identifier, PCI) of the historical cell. The historical cell is the cell where the historical serving beam of the terminal is located.

The identity information, the beam identifier and/or the time-frequency resource information of the beam; the beam is the beam corresponding to each reference signal of the historical cell. That is, the IDs, identifiers, and time-frequency resources of various reference signal beams in the cell to which the terminal belongs in the past.

Beam measurement information of the terminal's historical serving beam; that is, the measurement information of the service beam where the terminal used to be, specifically the measurement information of layers 1 and 3, such as Reference Signal Receiving Power (RSRP), Reference Signal Receiving Power (RSRP), reference Signal receiving quality (Reference Signal Receiving Quality, RSRQ), Received Signal Strength Indication (Received Signal Strength Indication, RSSI), Signal to Interference plus Noise Ratio (Signal to Interference plus Noise Ratio, SINR), Channel Quality Indicator (Channel Quality Indicator, CQI) and the like. The serving beam is a beam that serves the terminal in a connected state, or a beam that bears a reference signal of the terminal in a connected state.

Antenna panel (panel) information of historical service beams; that is, the antenna panel information of the service beams where the terminal used to be.

The dwell time length and dwell start and end time information of the terminal on the historical service beam; that is, the dwell time length of the terminal on the past serving beam and the start and end time of the dwell time. Alternatively, the length of time and the start and end times for the terminal to be out of service or out of coverage on the historical service beam.

The measurement time information and measurement location information corresponding to the beam measurement information of the historical service beam; that is, the terminal records the measurement amount information of a certain service beam in the past at different time points and different locations.

Quasi Co-Location (QCL) information of historical service beams; that is, from which antenna port the past service beams of the terminal were sent from, which is used to indicate which service beams are sent from the same antenna port.

Bitmap (bitmap) information of the synchronization signal block (Synchronous Signal Block, SSB) corresponding to the historical service beam; that is, the transmission position of the SSB configured by the broadcast and/or Radio Resource Control (Radio Resource Control, RRC) dedicated signaling in the system message bitmap information. For example, if the bitmap information of SSB is "00101100", the corresponding beams numbered 3, 5 and 6 are transmitting. If the bitmap information of SSB is changed to "01001100", the corresponding beams numbering 2, 5 and 6 are transmitting.

And the navigation information associated with the historical service beam, the navigation information is used to determine the historical position, speed, moving direction and angle of the terminal, specifically, the navigation information includes directly indicating the terminal's historical position, speed, moving direction and angle, etc. The inertial navigation information of the terminal can also be other information that can deduce the historical position, speed, moving direction and angle of the terminal. The navigation information may be reported jointly with beam measurement information of historical service beams.

Among them, it is worth pointing out that the beam history information is stored in a predefined variable, which can be configured by the network device or directly defined by the protocol.

Further, before step 11, the step of recording the beam history information of the terminal is also included, specifically: when the preset recording conditions are met, the corresponding beam information is recorded; and the beam history information of the terminal is generated according to the recorded beam information.

The preset recording conditions include at least one of the following:

The cell to which the terminal belongs changes; that is, the terminal changes the cell, which specifically includes changing the primary cell (Primary Cell, PCell), the secondary cell (Secondary Cell, SCell), and the primary/secondary cell (Primary/Secondary Cell, PSCell).

The network standard of the terminal changes; that is, the terminal changes the network standard to which it belongs, such as switching from the NR system to the LTE system, or switching from the LTE system to the NR system.

The service or coverage state of the terminal changes; specifically, the terminal switches from the in service or in coverage state to the out of service or out of coverage state, and the terminal switches from the out of service state. (out of service) or out of coverage (out of coverage) state switches to enter service (in service) or enter coverage (in coverage) state.

The antenna panel where the terminal is located is changed; that is, the antenna panel where the terminal is located, that is, the antenna panel where different beams are located, is changed.

The serving beam or the attached beam where the terminal is located is changed; wherein, the attached beam is the beam in which the terminal reads the SSB in an idle state.

The beam type used by the terminal changes; that is, the terminal switches from one beam to another, for example, the terminal switches from a beam using SSB to a beam using a Channel Status Indicator Reference Signal (CSI-RS).

The beam usage state of the reference signal corresponding to the terminal changes; for example, the terminal switches from the beam that uses/does not use the reference signal to the beam that does not use/use the reference signal.

The terminal recognizes that the intensity of the beam changes, the terminal recognizes the change of the strong/weak beam, and records the previous strong/weak beam.

The above describes the circumstances under which the terminal is triggered to record the beam information. In order to improve the availability of the recorded beam information, the terminal can filter part of the beam information according to preset conditions, and only retain the potentially useful beam information. Specifically: record the beam information whose beam quality or the number of beams exceeds the first preset threshold. It is worth pointing out that the first preset threshold is only used as a description of the threshold. Those skilled in the art should understand that the threshold corresponding to the beam quality is different from the threshold corresponding to the number of beams. The specific first preset threshold can be set according to the network equipment. The configuration settings can also be customized by the terminal, or directly defined by the protocol.

Further, the step of generating the beam history information of the terminal according to the recorded beam information can be specifically implemented by the following manner: sorting the recorded beam information according to a preset order to generate the beam history information of the terminal.

The preset sequence includes one of the following sequences:

The order of the frequency of the terminal camping on different beams; that is, the frequency of the terminal camping on some beams, which can be sorted according to the frequency.

The time sequence of the serving beams of the terminal; that is, the recording is performed according to the time sequence of the beams that have served the terminal.

The order of the quality of the serving beams of the terminal; that is, the records are sorted and recorded according to the quality of the beams that have served the terminal.

The time sequence of the beams measured by the terminal; that is, the terminal records according to the time sequence in which different beams are measured.

And, the quality order of the beams measured by the terminal, that is, the terminal records in order of the measured beam quality of different beams.

Further, due to the mobility of the terminal and the instability of the network state, the beam information related to the terminal will be continuously updated. In order to ensure the validity of the beam history information recorded by the terminal, the beam history of the terminal is generated according to the recorded beam information. The step of the information includes: if the number of the recorded beam information is greater than N, then select the N pieces of information closest to the current moment in the beam information to generate the beam history information of the terminal; wherein, N is the maximum number of records allowed by the beam history information, N is an integer greater than 1. Wherein N may be predefined by the terminal, or may be configured by the network device. It is worth pointing out that after generating the beam history information, if the terminal records new beam information, then the total number of beam information is greater than N, at this time, the earliest recorded beam information in the original beam history information is deleted, and the latest recorded beam information is deleted. The beam information is added to realize the continuous update of beam history information.

The beam history information, the beam history information recording, and the generation process have been described above. In this embodiment, passive reporting is taken as an example to describe the process of the terminal reporting the beam history information.

Specifically, when receiving a request to report the beam history information report request sent by the network device, the step of reporting the beam history information to the network device includes: receiving a query request sent by the network device to ask whether there is available beam history information; Request, query whether there is available beam history information; if so, feed back to the network device the feedback information that there is available beam history information; receive the request sent by the network device according to the feedback information to report the available beam history information report request; According to the report request , and report the available beam history information to the network device. The process here is: when the network device needs the terminal to report the beam history information, it first sends a query request to the terminal to query whether there is available beam history information, and when the terminal receives the query request, it queries whether there is an available beam. History information, if it exists, the feedback information of the available beam history information is fed back to the network device. After receiving the feedback information, the network device sends a report request for reporting the beam history information to the terminal, and the terminal reports the available beam history information to the network device according to the report request.

Or, in order to simplify the interaction process and save signaling overhead, when receiving a request to report the beam history information report request sent by the network device, the step of reporting the beam history information to the network device according to the report request includes: receiving an inquiry sent by the network device.
