At present, in a high-frequency band transmission system, higher forming gain and larger coverage can be realized by adopting beamforming transmission. The base station or the terminal usually obtains a better beamforming direction in a beam scanning manner. Beam scanning obtains a better beamforming direction by measuring signals in different beam directions. The process of beam scanning typically includes the processes of transmitting reference signals in different beam directions, signal quality measurements, beam selection, etc.

The more the number of antennas, the stronger the directivity of the beam, and the more the beam direction, the more the number of reference signals is required, the larger the overhead, and the higher the complexity of the calculation.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

For the convenience of clearly describing the technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if words such as "first" and "second" are used to distinguish the same items or similar items with basically the same functions and actions, those skilled in the art can understand that the words such as "first" and "second" do not limit the quantity and execution order.

As low-frequency band resources become scarce, and millimeter wave frequency bands have more spectrum resources, which can provide larger bandwidth, and become important frequency bands for future applications of mobile communication systems. The millimeter wave band has propagation characteristics different from the conventional low band spectrum, such as higher propagation loss, poor reflection and diffraction properties, etc., due to the shorter wavelength. Therefore, a larger-scale antenna array is usually adopted to form a shaped beam with a larger gain, so as to overcome the propagation loss and ensure the system coverage. For the millimeter wave antenna array, as the wavelength is shorter, the antenna array spacing and the aperture are smaller, more physical antenna arrays can be integrated in a two-dimensional antenna array with a limited size; meanwhile, because the millimeter wave antenna array has a limited size, the digital beam forming mode adopted by the low frequency band cannot be adopted due to the consideration of factors such as hardware complexity, cost overhead and power consumption, and a hybrid beam forming mode combining an analog beam and a limited digital port is usually adopted.

For a multi-antenna array, each antenna has an independent rf link channel but shares the same digital link channel, each rf link allows independent amplitude and phase adjustment of the transmitted signal, and the formed beam is mainly realized by phase and amplitude adjustment in the rf link, which is called analog beamforming signal. And each antenna of the full digital beam forming antenna array has an independent digital link channel, and the amplitude and the phase of each path of signals can be controlled at a baseband.

However, in the conventional beam scanning technique, in order to obtain an optimal beam in a plurality of beam directions, it is necessary to transmit a reference signal in each of the plurality of beam directions, measure signal quality of each of the plurality of beam directions, and select an optimal beam. The more the number of antennas, the stronger the directivity of the beam, and the more the beam direction, the more the number of reference signals is required, the larger the overhead, and the higher the complexity of the calculation. Therefore, in a scenario where a super-large-scale antenna is deployed, how to perform low-overhead and low-complexity beam scanning is an urgent problem to be solved.

Because the phase of a signal sent by each antenna is generally changed by a phase shifter during analog beamforming, the analog beamforming is limited by the limitation of device capability, the analog beamforming is performed on the whole bandwidth, and cannot be performed separately like digital beamforming on a partial molecular band, so that Multiplexing needs to be performed in a TDM (Time Division Multiplexing) manner during analog beamforming. The fact that there are more beam directions means that the time required for beam scanning is long. In a high-speed mobile scene, the channel environment changes rapidly, and the optimal beam direction and the serving site change rapidly. If the conventional beam scanning technology is still adopted, the change condition of the beam may not be tracked in time, thereby causing beam failure or radio link failure and affecting the performance.

In view of the foregoing problems, embodiments of the present invention provide a beam recommendation method, apparatus, network side device, terminal, and storage medium, so as to reduce the time and overhead of beam scanning.

The beam recommendation method, the beam recommendation device, the network side equipment, the terminal and the storage medium provided by the embodiment of the invention can be applied to a wireless communication system or a wireless and wired combined system. Including but not limited to 5G systems (e.g., NR systems), 6G systems, satellite systems, car networking systems, Long Term Evolution (LTE) systems, and subsequent Evolution communication systems of the above systems.

The network side device provided by the embodiment of the present invention may include, but is not limited to, one or more of the following: generally, a base station, an evolved node base (eNB), a network side device in a 5G system (e.g., a next generation base station (gNB), a Transmission and Reception Point (TRP)), and other devices are used.

The terminal provided by the embodiment of the invention can be called as user equipment and the like. The terminal includes but is not limited to handheld devices and vehicle-mounted devices. For example, the Mobile phone may be a Mobile phone, a tablet pc, a notebook pc, an Ultra-Mobile Personal Computer (UMPC), a netbook, a Personal Digital Assistant (PDA), or the like.

The following description will be made by way of specific examples.

Fig. 1 is a flowchart of a beam recommendation method according to an embodiment of the present invention, where the beam recommendation method may be used in a network side device, such as a base station. As shown in fig. 1, the beam recommendation method includes the following steps:

step 110: a beam database or beam model for beam recommendation is determined.

Specifically, in a track traffic or urban road traffic scene, because the distribution of tracks and roads has a certain regularity, the activities of users on the tracks and roads are limited to the track or road regularity, and also have a certain regularity. The regularity of the user's motion may result in regular variations of the measurement information. The base station can obtain the rule according to the historical information reported by all users in the cell. According to the rule, beam recommendation can be carried out on the current user, so that the aim of saving expenses is achieved.

The network side equipment (such as a base station) establishes a beam database or a beam model based on beam information reported by users served by the network, and when one user reports the beam quality information, the network side can match the database according to the beam quality information of the user or input the beam quality information of the user into a mathematical model to obtain a better beam direction of downlink transmission or uplink transmission. The beam information may include beam quality information (e.g., RSRP, BLER, etc.) and/or beam identification information, among others. The Reference Signal quality information may be RSRP (Reference Signal Receiving Power), BLER (BLock Error Rate), or the like.

The network side equipment can respectively establish a beam database or a beam model aiming at each terminal; a beam database or beam model may also be established for multiple terminals.

Step 120: and receiving first beam information for beam recommendation sent by the terminal.

Specifically, the first beam information may include information obtained by the terminal in an uplink transmission manner, for example: the terminal sends an uplink signal for measuring the beam quality according to the configuration or the indication of the network side equipment; the information obtained by using the downlink transmission mode may also be included, for example: and the terminal measures according to the downlink signal sent by the network side equipment to obtain the beam quality information corresponding to the downlink signal.

Step 130: and determining a recommended beam for signal transmission and/or a change trend of the recommended beam according to the first beam information and a beam database or a beam model. The signal transmission comprises uplink signal transmission or downlink signal transmission.

Specifically, the network side device (for example, the base station) may perform operations such as matching, comparing, fitting, and retrieving on the beam quality information determined according to the first beam information and a database, so as to obtain a recommended beam for signal transmission and/or a variation trend of the recommended beam; the beam quality information determined from the first beam information may also be input to a beam model to obtain a recommended beam for signal transmission and/or a variation trend of the recommended beam.

Wherein the recommended beam may be a better beam determined from the first beam information and the beam database or beam model. The variation trend of the recommended beam may be a variation in beam quality of a plurality of beams recommended at the position of the terminal, a possible beam variation of the terminal in the subsequent movement direction, or a better beam including one or more different positions of the terminal in the subsequent movement trajectory. The number of recommended beams may be one or more. The currently determined recommended beam may be the same as or different from the recommended beam used for the previous signal transmission.

In addition, the process that the network side device (for example, the base station) determines the recommended beam for signal transmission and/or the variation trend of the recommended beam according to the first beam information reported by the terminal, and the beam database or the beam model may be an iterative process.

When a network side device (e.g., a base station) determines one or more recommended beams of a terminal for the first time according to beam information reported by the terminal and a beam database or a beam model, the network side device (e.g., the base station) transmits reference signals on the one or more beams, for example: CRS (Cell Reference Signal) and indicates to the terminal, which monitors the Reference Signal quality on these multiple beams, such as: and RSRP, and reporting the beam information meeting the requirement to the base station according to a predefined criterion. And the network side equipment (such as a base station) determines the recommended beam again according to the information reported by the terminal and the beam database or the beam recommendation model. The above process is repeated. Wherein the predefined criteria include that the RSRP quality is best, or the reception quality is greater than a certain threshold, etc.

Such as: the network side equipment (such as a base station) can send downlink signals on the recommended beam and the beam of the downlink signals sent by the network side equipment to the terminal for measurement last time; the terminal receives the reference signal sent on the wave beam and reports the optimal wave beam information to the network side equipment according to a predefined criterion (such as the best RSRP quality); and the network side equipment selects a better beam according to the beam information reported by the terminal.

As can be seen from the above embodiments, by determining the beam database or the beam model for beam recommendation, when first beam information for beam recommendation sent by a terminal is received, a recommended beam for signal transmission and/or a variation trend of the recommended beam can be determined according to the first beam information and the beam database or the beam model, so that the problems of large overhead and time delay caused by frequent beam scanning in a high-speed scene are solved, beam scanning time and beam overhead are saved, and beam recommendation efficiency and accuracy are improved.

Further, based on the above method, the beam database or the beam model determined in step 110 for beam recommendation may be implemented by, but not limited to:

(1-1-2) determining the beam database or beam model according to the second beam information.

Specifically, when the network side device establishes the beam database, the following procedure may be adopted for all terminals in the cell.

A downlink process: the network side device sends downlink signals for beam measurement on one or more beams, such as CRS, CSI-RS (Channel State Indication-Reference Signal), and the like), respectively, and the terminal detects the signals sent on the one or more beams and reports the beam information meeting the requirements to the network side device according to a preset criterion. And the network side equipment stores the beam information reported by the terminal into a beam database and/or selects beams according to the beam information reported by the terminal and stores the information of the selected beams into the beam database.

An uplink process: the network side device configures or instructs the terminal to respectively send uplink signals on one or more beams, such as: SRS (Sounding Reference Signal), PRACH (Physical Random Access Channel), and the like, a network side device measures the uplink Signal sent by the terminal, the network side device stores a measurement result to a beam database according to a preset criterion and/or the network side device performs beam selection according to the measurement result, and stores information of the selected beam in the beam database.

The beam database stores the variation trend of the beam information reported by the terminal (the relationship between the motion track and/or position of the terminal and the beam quality information and/or the beam identification information). Optionally, the network side device further estimates the position and/or the motion trajectory of the terminal by using the beam measurement result, and stores the position and/or the motion trajectory of the terminal in a beam database. Optionally, the beam database stores the relationship between the position and/or motion trajectory of the terminal and the beam measurement information.

In addition, when the network side device establishes the beam model, the process of establishing the beam database can be repeatedly adopted for all terminals in the cell to collect information, and the collected information is used for establishing the beam model. Such as: and determining the track of the user according to the collected information data, and determining a beam model according to the track information.

As can be seen from the above embodiments, by obtaining second beam information reported by all terminals in a designated area within a designated time period, where the second beam information includes beam quality information and/or beam identification information, and determining the beam database or the beam model according to the second beam information, reliability of the beam database or the beam model is ensured.

(1-8-1) determining a moving direction of the terminal according to the first beam information and the track information or road information.

Specifically, if the network-side device stores track or road information in advance, the network-side device may determine a movement direction of the terminal according to the first beam information reported by the terminal and the track information or road information, and determine a recommended beam used by the terminal for signal transmission and/or a variation trend of the recommended beam according to the movement direction of the terminal and each beam mapping relationship included in a beam database or a beam model, for example: current optimal beam information.

(1-8-2) determining a recommended beam for signal transmission and/or a variation trend of the recommended beam according to the movement direction of the terminal and the beam mapping relation.

As can be seen from the above embodiments, since the beam database or the beam model includes the track information or the road information, the motion direction of the terminal may be determined according to the first beam information and the track information or the road information, and then the recommended beam for signal transmission and/or the change trend of the recommended beam may be determined according to the motion direction of the terminal and the beam mapping relationship, thereby enriching implementation manners for determining the motion direction of the terminal and improving flexibility for determining the motion direction of the terminal.

Further, based on the foregoing method, the beam recommendation method further includes the following steps:

(1-9-1) updating the beam database or the beam model according to the first beam information to obtain an updated beam database or beam model.

Specifically, the network side device may update the beam database or the beam model. When receiving first beam information reported by a terminal, if the first beam information comprises an uplink signal for beam quality measurement, the network side equipment measures the quality of the uplink signal to obtain beam quality information and/or beam identification information corresponding to the uplink signal, and then updates a beam database or a beam model by using the beam quality information and/or beam identification information corresponding to the uplink signal; if the first beam information includes beam quality information and/or beam identification information corresponding to the downlink signal, the beam database or the beam model may be directly updated using the beam quality information and/or the beam identification information corresponding to the downlink signal.

As can be seen from the above embodiments, the updated beam database or beam model is obtained by updating the beam database or beam model according to the first beam information, which is convenient for subsequently using the updated beam database or beam model to recommend beams, thereby ensuring the accuracy and real-time of the beam database or beam model and further improving the reliability of beam recommendation.

Fig. 2 is a flowchart of a beam recommendation method according to an embodiment of the present invention, where the beam recommendation method may be used for a terminal; as shown in fig. 2, the beam recommendation method includes the following steps:

step 210: first beam information for beam recommendation is determined.

Step 220: and sending the first beam information to network side equipment so that the network side equipment determines a recommended beam for signal transmission and/or a change trend of the recommended beam according to the first beam information and a beam database or a beam model. The signal transmission comprises uplink signal transmission or downlink signal transmission.

In particular, the recommended beam may be a better beam determined from the first beam information, and the beam database or beam model. The variation trend of the recommended beam may be a variation in beam quality of a plurality of beams recommended at the position of the terminal, a possible beam variation of the terminal in the subsequent movement direction, or a better beam including one or more different positions of the terminal in the subsequent movement trajectory. The number of recommended beams may be one or more. The currently determined recommended beam may be the same as or different from the recommended beam used for the previous signal transmission.

As can be seen from the above embodiments, by determining first beam information for beam recommendation, the first beam information is sent to the network side device, so that the network side device can determine a recommended beam for signal transmission and/or a variation trend of the recommended beam according to the first beam information and a beam database or a beam model; the signal transmission comprises uplink signal transmission or downlink signal transmission, so that the problems of large overhead and time delay caused by frequent beam scanning in a high-speed scene are solved, the beam scanning time and the beam overhead are saved, and the beam recommendation efficiency and accuracy are improved.

Further, based on the above method, the determining the first beam information for beam recommendation in step 210 may employ, but is not limited to, the following implementation manners:

(2-1-1) receiving network side configuration information or indication information sent by the network side equipment, where the network side configuration information or indication information is used to indicate the terminal to send an uplink signal for beam quality measurement.

(2-1-2) determining the uplink signal for beam quality measurement as the first beam information.

It can be seen from the above embodiments that, by sending the uplink signal for beam quality measurement to the network side device, the network side device can measure the quality of the uplink signal to obtain beam quality information corresponding to the uplink signal, and further according to the beam quality information and a recommended beam for signal transmission and/or a variation trend of the recommended beam in a beam database or a beam model, beam scanning time and beam overhead are saved.

(2-2-1) receiving a downlink signal for beam quality measurement sent by the network side equipment; .

(2-2-2) measuring the quality of the downlink signal, and determining beam quality information and/or beam identification information corresponding to the downlink signal according to the measurement result.

Specifically, the terminal measures the quality of the downlink signal, and may obtain beam quality information corresponding to one or more beams in the downlink signal.

(2-2-3) determining the beam quality information and/or the beam identification information corresponding to the downlink signal as the first beam information.

As can be seen from the above embodiments, by receiving a downlink signal for beam quality measurement sent by a network side device, measuring the quality of the downlink signal to obtain beam quality information corresponding to the downlink signal, and sending the beam quality information and/or beam identification information corresponding to the downlink signal to the network side device, the network side device can use the beam quality information and a recommended beam for signal transmission in a beam database or a beam model and/or a variation trend of the recommended beam, thereby saving beam scanning time and beam overhead and reducing time delay caused by a beam scanning process.

The following describes a beam recommendation method illustrated in fig. 1 and 2 by using a specific example.

Example 1: the network side collects the beam quality measurement information of a plurality of terminals and establishes a beam change trend database of the terminals according to the information of the users. The beam change trend of the terminal is obtained through the beam quality information and/or the beam identification information obtained once or for multiple times, and the change trend is compared with the database to obtain a better beam, so that the accuracy of recommending the beam is improved.

Example 2: the network side collects the beam quality measurement information of a plurality of terminals and establishes a beam model of the terminal according to the information of the users. And the network side inputs the beam quality information and/or the beam identification information obtained once or for many times into the beam model to obtain the change trend of the better beam and/or the better beam.

One specific implementation of example 2: the terminal reports the wave beam identification information of M wave beams with the best quality in two reports respectively, and the network side stores the mapping relation between the change of the wave beam identification information and the change trend of the superior wave beam/the superior wave beam. The network side can obtain the better beam and/or the change trend of the better beam according to the mapping relation. As shown in table 1: under the mapping relationship, if the beam identifiers reported by the terminal for the first time are beam 1, 2, and 3, and the beam identifiers reported for the second time are beam 2, 3, and 4, the network side knows that the current optimal beam is beam 2, and the optimal beam will become beam 3 after a certain time along with the movement of the terminal.
