Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In order to clearly describe the technical solutions of the embodiments of the present invention, in each embodiment of the present invention, if "first", "second", and the like words are used to distinguish the same item or similar items having substantially the same function and effect, those skilled in the art will understand that the "first", "second", and the like words do not limit the number and execution order.

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

For a multi-antenna array, each antenna has an independent radio frequency link channel, but shares the same digital link channel, each radio frequency link allows independent amplitude and phase adjustment of the transmitted signal, and the formed beam is realized mainly by phase and amplitude adjustment in the radio frequency channel, which is called an analog beamforming signal. And the all-digital wave beam forming antenna array has independent digital link channels for each antenna, and can control the amplitude and phase of each signal in the 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 reference signals in the plurality of beam directions, respectively, measure signal quality, and select an optimal beam. The more antennas, the stronger the beam directivity, the more beam directions, the more reference signals are needed, the greater the overhead and the higher the computational complexity. Therefore, in the scenario where a very large-scale antenna is deployed, how to perform low-overhead, low-complexity beam scanning is an urgent problem to be solved.

Because the phase of the signal transmitted by each antenna is generally changed by the phase shifter during the analog beamforming, the phase shifter is limited by the limitation of the device capability, the analog beamforming is performed on the whole bandwidth and cannot be performed on part of the sub-bands independently like the digital beamforming, and therefore multiplexing is needed between the analog beamforming in a TDM (Time Division Multiplexing ) mode. The large number of beam directions means that a long time is required for beam scanning. In a high-speed mobile scenario, the channel environment changes rapidly, and the optimal beam direction and service station change rapidly. If the traditional beam scanning technology is still adopted, the change condition of the beam cannot be tracked in time, so that the beam failure or the radio link failure is caused, and the performance is affected.

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

The beam recommending method, the 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 wire-bonding system. Including but not limited to 5G systems (e.g., NR systems), 6G systems, satellite systems, internet of vehicles systems, evolved long term evolution (Long Term Evolution, LTE) systems, subsequent evolution communication systems of such systems, and the like.

The network side device provided by the embodiment of the invention can include, but is not limited to, one or more of the following: commonly used base stations, evolved base stations (evolved node base station, enbs), network-side devices in 5G systems (e.g., next generation base stations (next generation node base station, gNB), transmission and reception points (transmission and reception point, TRP)), and the like.

The terminal provided by the embodiment of the invention can be called user equipment and the like. The terminal comprises a handheld device and a vehicle-mounted device. For example, it may be a cell phone, tablet, notebook, ultra mobile personal computer (Ultra-Mobile Personal Computer, UMPC), netbook or personal digital assistant (Personal Digital Assistant, PDA), etc.

The following is a description 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 for a network side device, for example, 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.

In particular, in a track traffic or urban road traffic scenario, since the distribution of tracks and roads has a certain regularity, the activities of users thereon are limited to the track or road regularity, and also have a certain regularity. The regularity of the user's movement may lead to regular changes in the measured 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 performed on the current user, so that the purpose of saving cost is achieved.

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

The network side equipment can respectively establish a beam database or a beam model for each terminal; a beam database or beam pattern may also be established for a plurality of 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; information obtained by adopting a downlink transmission mode can also be included, for example: the terminal measures according to the downlink signal sent by the network side equipment, and the obtained 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. Wherein the signal transmission includes uplink signal transmission or downlink signal transmission.

Specifically, the network side equipment (such as a base station) can perform operations such as matching, comparing, fitting, searching and the like on the beam quality information determined according to the first beam information and a database to obtain a recommended beam for signal transmission and/or a change 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 trend of change of the recommended beam.

Wherein the recommended beam may be a preferred beam determined from the first beam information and the beam database or beam model. The trend of the recommended beam may be a beam quality change of a plurality of recommended beams at the position of the terminal, or a possible beam change of the terminal in the subsequent movement direction, or a preferred beam of the terminal at one or more different positions on the subsequent movement track. 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 of the network side device (such as the base station) determining the recommended beam for signal transmission and/or the change trend of the recommended beam according to the first beam information reported by the terminal and the beam database or the beam model can be an iterative process.

When the network side device (such as a base station) determines one or more recommended beams of the terminal according to the beam information reported by the terminal and the beam database or the beam model for the first time, the network side device (such as the base station) sends 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 the multiple beams, such as: and reporting the beam information meeting the requirements to the base station according to the RSRP. The network side equipment (such as a base station) determines a recommended beam according to the information reported by the terminal and a beam database or a beam recommendation model. The above process is repeated. Wherein the predefined criteria include that RSRP is best quality, or that the received quality is greater than a certain threshold value, etc.

Such as: the network side equipment (such as a base station) can send downlink signals on the recommended wave beam and the wave beam of the downlink signals which are used for measurement and sent to the terminal by the network side equipment at the 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 that the RSRP quality is best); and the network side equipment selects a better wave beam according to the wave 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 the first beam information for beam recommendation sent by the terminal is received, the recommended beam for signal transmission and/or the 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 cost and time delay caused by frequent beam scanning in a high-speed scene are solved, the beam scanning time and the beam cost are saved, and the beam recommendation efficiency and accuracy are also improved.

(1-1-2) determining the beam database or beam pattern from 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.

The downlink process comprises the following steps: the network side device respectively transmits downlink signals for beam measurement, such as CRS, CSI-RS (Channel State Indication-Reference Signal, channel state indication Reference Signal), etc., on one or more beams, and the terminal detects the signals transmitted on the one or more beams and reports the beam information meeting the requirements to the network side device according to a preset criterion. The network side equipment stores the beam information reported by the terminal into a beam database and/or performs beam selection according to the beam information reported by the terminal, and stores the information of the selected beam into the beam database.

And (3) an uplink process: the network side device configures or instructs the terminal to transmit uplink signals on one or more beams, for example: SRS (Sounding Reference Signal, uplink sounding reference signal), PRACH (Physical Random Access Channel ), etc., the network side device measures the uplink signal sent by the terminal, the network side device stores the measurement result into the beam database according to a preset criterion and/or the network side device performs beam selection according to the measurement result, and the information of the selected beam is stored into the beam database.

The beam database stores the change trend of the beam information reported by the terminal (the relation between the motion track and/or the position of the terminal and the beam quality information and/or the beam identification information). Optionally, the network side device further uses the beam measurement result to estimate the position and/or the motion track of the terminal, and stores the position and/or the motion track of the terminal into the 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 equipment builds the beam model, the process of building the beam database can be repeatedly adopted for all terminals in the cell to collect information, and the collected information is used for building the beam model. Such as: and determining the track of the user according to the collected information data, and determining the beam model according to the track information.

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

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

And acquiring the beam change trend of the terminal through the beam quality information and/or the beam identification information acquired one or more times, and comparing the change trend with a database to acquire a better beam, thereby improving the accuracy of the recommended beam.

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

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