1 is a diagram illustrating multiple antenna panels included in a terminal according to an embodiment. Referring to FIG. 1, multiple antenna panels 110, 120, and 130 included in the terminal 100 according to an embodiment are illustrated. In one embodiment, for convenience of description, a case in which the terminal 100 includes three multi-antenna panels is described, but the present invention is not limited thereto, and the terminal 100 may include various numbers of multi-antenna panels.

The terminal 100 according to an embodiment is a terminal conforming to the 3GPP 5G standard and may support millimeter wave (mmWave) frequencies. The millimeter-wave band radio channel for 5G communication can provide a wide bandwidth, and can have high straightness and large path loss due to high frequency characteristics.

In order to reduce path loss, the terminal 100 efficiently estimates a sparse channel through, for example, a pilot signal and beam training, and then performs high directivity beam forming. Path loss can be overcome. In an embodiment, multiple antenna panels 110, 120, and 130 including a plurality of antennas may be used for beamforming with high directivity. Since the millimeter wave has a short wavelength, the multiple antenna panels 110, 120, and 130 can integrate a plurality of antennas in a small space. In an embodiment, beamforming between the base station and the terminal 100 may be performed using multiple antenna panels 110, 120, and 130 including a plurality of antennas. Each of the multiple antenna panels 110, 120, and 130 may have an antenna array including a plurality of antennas. Hereinafter, for convenience of description, the multi-antenna panel may be simplified and expressed as an “antenna panel”.

Directions of at least one usable beam radiated from a plurality of antennas included in each of the multiple antenna panels 110, 120, and 130 may not overlap each other. In addition, if all available beams radiated from a plurality of antennas included in each of the multiple antenna panels 110, 120, and 130 are combined, the terminal 100 may generate beams in all directions.

In one embodiment, prior to beamforming, a best beam pair link (BPL) between the beam of the base station and the beam of the terminal may be formed for transmission and reception between the base station and the terminal 100.

In the mmWave band determined by 3GPP, communication may be performed in a time division duplexing (TDD) method, for example. In the time division duplex (TDD) scheme, since the downlink and uplink channel environments are the same, the best reception beam may be the best transmission beam. Accordingly, when a beam pair link is formed in the time division duplex scheme, the corresponding beam pair can be the best beam that can be used for reception and transmission in each of the base station and the terminal.

For example, suppose that a base station supports 60 beams, a terminal supports 5 beams, and measures signal strength between all beams available in the base station and the terminal to form a beam pair link. In this case, any one of the five beams of the terminal is fixed, the signal strength of 60 beams of the base station is measured, and then the signal strengths of the 60 beams of the base station are similarly calculated for the remaining beams of the terminal. You have to measure it. In other words, since it is necessary to measure the signal strength of a total of 300 (60x5) times, it may take a long time to form a beam pair link. In addition, in the case of a millimeter wave, the time length of a symbol, which is the most basic unit containing data, is short, so if it takes a long time to form a beam pair link, data may not be normally exchanged.

In one embodiment, instead of measuring the signal strength of all beams in a terminal including multiple antenna panels, a beam pair link is formed by measuring the signal strength of an available beam of any one antenna panel selected from the multiple antenna panels. You can reduce the time spent on

2 is a flowchart illustrating a method of forming a beam pair link according to an embodiment. Referring to FIG. 2, a terminal according to an embodiment determines representative beams for each of multiple antenna panels including a plurality of antennas (210). A method for the UE to determine representative beams will be described in detail with reference to FIGS. 3 to 4 below.

The terminal selects one of the multiple antenna panels among the multiple antenna panels based on the first signal strength between each of the representative beams determined in step 210 and the beam of the base station (220). In step 220, the terminal may measure first signal strengths between each of the representative beams and the beam of the base station. The terminal may select any one multi-antenna panel corresponding to the representative beam for which the highest signal strength is measured among the first signal strengths.

The terminal selects any one beam based on the second signal strength between at least one usable beam and the beam of the base station among the plurality of beams of the multi-antenna panel selected in step 220 (230). In step 230, the terminal may measure a second signal strength between at least one usable beam of a plurality of beams of the selected multi-antenna panel and a beam of the base station. The terminal may select any one beam having the highest signal strength among the second signal strengths.

The terminal establishes a beam pair link between the beam selected in step 230 and the beam of the base station (240). The terminal may communicate with the base station through the beam pair link formed in step 240.

Referring to FIG. 3, virtual lines (L _{abs,i -j} ) connecting the center point of the antenna panel i and the center point of the antenna panel j, representative lines of the antenna panels (L _rep,i ) according to an embodiment, And representative beams B _{rep,i for each} antenna panel are shown.

The terminal according to an embodiment may generate virtual lines L _{abs,i -j} connecting the centers of each of the multiple antenna panels. For example, suppose that the terminal includes three multi-antenna panels 110, 120, and 130. Multi-antenna user terminal panel 1 110, panel 2, and a multi-antenna 120 of the virtual line connecting the respective centers of _- may generate a (L _{abs, 1 2).} Terminal is a multi-antenna panel 2 120, and a multi-antenna panel 3 (130) the virtual lines connecting the respective centers of (L _{abs, 2 - 3),} the generation, and a multi-antenna panel 3 (130) and a multi-antenna panel 1 (110) A virtual line (L _{abs, 1-3} ) connecting each center may be generated.

The terminal may determine representative lines L _rep,i representing each of the multi-antenna panels based on the virtual lines L _{abs and} ij. For example, the terminal represents a multi-antenna panel 1 (110) based on a virtual line (L _{abs,1 -2} ) and a virtual line (L _abs,1-3 ) connected to the multi-antenna panel 1 (110). It is possible to determine the representative line (L _rep,1 ). The terminal is a representative line representing the multi-antenna panel 2 120 based on a virtual line (L _{abs,1 -2} ) and a virtual line (L _abs,2-3 ) connected to the multi-antenna panel 2 120 ( L _rep,2 ) can be determined. The terminal is a representative line representing the multi-antenna panel 1 110 based on a virtual line (L _{abs,2 -3} ) and a virtual line (L _abs,1-3 ) connected to the multi-antenna panel 3 130 ( L _rep,2 ) can be determined. In this case, a method of determining the representative lines L _rep,i based on the virtual lines L _{abs,i -j} will be described in detail with reference to FIG. 4 below.

For each of the multiple antenna panels, the terminal may determine a beam having the smallest angular difference from the representative line among the generated beams as representative beams B _rep,i . For example, among the beams that can be generated by the multi-antenna panel i, the terminal _{selects the} beam with the smallest angular difference from the representative line (L _rep,i ) representing each antenna panel as the representative beam (B _rep,i ) for each antenna panel. You can decide. Here, the representative beams B _{rep,i for each} antenna panel may correspond to, for example, a beam farthest from each of the virtual lines L _abs,ij .

The terminal may select any one of the multiple antenna panels 110, 120 and 130 based on the first signal strength between the representative beams B _rep,i and the beam of the base station. For example, the terminal may fix a beam to one of the representative beams (B _rep,i ) and measure a first signal strength with the beam of the base station. After the measurement, the terminal may fix the beam as another representative beam and measure the first signal strength with the beam of the base station again. The terminal may repeat the process of measuring the first signal strength with the beam of the base station for each of the representative beams (B _rep,i ). The terminal may form a beam pair link with a beam of the base station by selecting a beam of a multi-antenna panel whose first signal strength with a beam of the base station is the largest among the representative beams B _rep,i .

Referring to FIG. 4, a terminal according to an exemplary embodiment provides a multi-antenna panel 1 based on a virtual line (L _abs , _{1 -2} ) and a virtual line (L _abs , _1-3 ) connected to the multi-antenna panel 1. A method of determining a representative representative line (L _rep , ₁ ) is shown.

Terminal is a representative line (L _{rep, 1)} the angle between the imaginary line (L _{abs, 1 -2)} and a virtual line (L _{abs, 1 -3)} respectively, and the representative line (L _{rep, 1)} to be equal to You can decide. In other words, the terminal of a virtual line (L _{abs, 1 - 2)} and the representative line (L _{rep, 1)} the angle between (θ ₁₎ and a virtual line (L _{abs, 1 - 3)} and the representative line (L _rep The representative line (L _rep , ₁ ) can be determined so that the angle (θ ₂ ) between, ₁ ) becomes the same. _This-may be expressed in words, unlike the 'virtual line (L _{abs, 1 -2)} and a virtual line (L _{abs, 1 3)} and determines the representative line that bisects the cabinet according to the (L _{rep, 1)'} . Here, the internal angle may correspond to all angles made by two adjacent sides of the polygon inside the polygon.

In one embodiment, for convenience of explanation, a method of determining the representative line (L _rep,1 ) is described, but the representative line (L _rep,2 ) and the representative line (L _rep,3 ) are also the representative line (L _{rep). ,1} ) can be determined in the same way.

5 is a flowchart illustrating a method of forming a beam pair link according to another embodiment. Referring to FIG. 5, the terminal according to an embodiment may generate a virtual line (L _{abs,i -j} ) connecting the center of each antenna pattern (505 ). After setting 510 of the antenna panel index (i) = 1, the terminal may determine whether the value of the index (i) of the corresponding antenna panel is less than or equal to the total number of antenna panels (N _p ) of the terminal. (515).

If it is determined in step 515 that the antenna panel i is less than or equal to the total number of antenna panels of the terminal (N _p ), the terminal is the farthest from all virtual lines (L _{abs,i -j} ) connected to the antenna panel i. The separated virtual line (L _rep,i ) may be determined (520 ). Here, the farthest virtual line (L _rep,i ) may correspond to _{a'representative} line (L _rep,i ) representing the antenna panel i'. In step 520, for the other antenna panel j connected to the antenna panel i, the terminal performs a virtual line (L _i ) in the antenna panel i and a virtual line (L) connecting the center point of the antenna panel i and the center point of the antenna panel j. An imaginary line (L _i ) that makes the angle θ _{i,i -j} between _{abs,i -j} ) become the same may be determined as the representative line (L _rep,i ). In this case, j ≠ i and 1 ≤ j ≤ the number of antenna panels of the terminal (N _p ).

After the terminal sets the index k = 1 of the available beams of antenna panel i (525), whether the value of the index (k) of the corresponding beam is less than or equal to the number of available beams (Nb, i) of the antenna panel i Can be determined (530). In step 530, if it is determined that the value of the index (k) of the corresponding beam is greater than the number of beams (Nb, i) available in the antenna panel i, the terminal sets the index (i) of the antenna panel i = i + 1 It can be increased by 1 as in (545). Thereafter, the terminal may determine whether the value of the index i of the corresponding antenna panel is less than or equal to the number of total antenna panels N _p of the terminal (515 ).

In step 530, if it is determined that the value of the index (k) of the corresponding beam is less than or equal to the number of beams available in antenna panel i (Nb,i), the k-th beam (B _i,k ) of antenna panel i The beam angle (θ _i ) between the representative beam (B _rep,i ) of the antenna panel i and the k-th beam (B _i,k ) of the antenna panel i is compared with the representative line (L _rep,i ) representing the antenna panel i. _,k ) can be calculated (535). Thereafter, the terminal increases the beam index k of antenna panel i by 1 such as k = k+1 (540), and then the value of the index k of the corresponding beam is the number of beams available in antenna panel i (Nb, i It may be determined whether it is less than or equal to) (530).

In contrast, if it is determined in step 515 that the index (i) of the antenna panel is greater than the number of total antenna panels (N _p ) of the terminal, the terminal initializes the index (i) of the antenna panel to index (i) = 1. Can do (550).

The terminal may determine once again whether the index (i) of the antenna panel is greater than the total number of antenna panels (N _p ) of the terminal (555).

If it is determined in step 555 that the index (i) of the antenna panel is less than or equal to the number of total antenna panels (N _p ) of the terminal, the terminal has the representative beam (B _rep,i ) of the antenna panel i and the beam of the base station Intensity can be measured (560).

Thereafter, the terminal increases the antenna panel index (i) by 1 such as I = i+1 (565), and then the increased antenna panel index (i) is less than the total number of antenna panels (N _p ) of the terminal. It can be determined whether or not (555).

If it is determined in step 555 that the index (i) of the antenna panel is greater than the number of total antenna panels (N _p ) of the terminal, the terminal measures the largest signal strength among the representative beams (B _rep,i ) of the antenna panel i. The antenna panel corresponding to the value of the index i may be determined as the antenna panel P of the terminal to be used to form the beam pair link BPL (570 ).

After initializing the beam index k of the antenna panel to 1 (575), the terminal may determine whether it is less than or equal to the number of beams (N _b,p ) of the antenna panel P (580). If it is determined in step 580 that the beam index k is less than or equal to the number of beams (N _b,p ) of the antenna panel (P), the terminal selects the k-th beam (B _p,k ) from the antenna panel (P). After measuring the beam intensity with the beam of the base station (585) _, it may be determined whether it is less than or equal to the number of beams (N _b,p ) of the antenna panel P by increasing the beam index k (580).

If it is determined in step 580 that the beam index k is greater than the number of beams (N _b,p ) of the antenna panel (P), the terminal is the largest among the k-th beams (B _p,k ) of the antenna panel (P). The beam corresponding to the k value at which the signal strength is measured may be determined as the beam (B _rep ) of the terminal to be used when forming the BPL (590 ). The terminal may form a beam pair link with the base station by the beam B _rep determined in step 585 (595).
