The coverage 711 of TRP A 701 and the coverage 712 of TRP B 702 may be different, the same, or partially overlap each other. The TRP A 701 and the TRP B 702 may be connected to a base station device 703 (eg, a digital unit (DU)). 7 means that TRP A 701 and TRP B 702 transmit the same demodulation reference signal (DMRS) ports (eg, DMRS ports A and B in both TRPs) for the same PDSCH data transmission. can In this case, the electronic device 101 may receive one downlink control information (DCI) information for receiving one PDSCH data demodulated based on DMRS transmitted through DMRS ports A and B.

The electronic device 101 can check information on the number and index of DMRS ports for PDSCH, the number of front-load symbols, and the number of CDM groups based on the indicator (index) transmitted by the base station. In addition, based on the information of the TCI field in DCI 1_1, a change in the beamforming direction may be dynamically determined. If tci-PresentDCI is set to 'enabled' in the upper layer, the electronic device 101 checks the TCI field of 3 bits information to determine the TCI states activated in the DL BWP or scheduled component carrier. It is possible to determine the direction of a beam associated with DL-RS. Conversely, if tci-PresentDCI is set to 'disable', it can be considered that there is no change in the beam direction of beamforming.

It can be determined based on the QCL parameters used. As another example, when the scheduling offset/scheduling timing offset between the PDCCH and the PDSCH is greater than or equal to timeDurationForQCL, the electronic device 101 applies the QCL assumption indicated by the TCI field in the PDCCH (eg, DCI) to the corresponding PDSCH DMRS port. can do.

16 is a diagram illustrating reception beam selection in the NC-JT system according to various embodiments. Referring to FIG. 16 , the electronic device 101 may include a plurality of antenna modules (eg, the third antenna module 246 of FIG. 4 ). In the following description, for convenience of explanation, as shown in FIG. 16 , the electronic device 101 is illustrated as including two antenna modules, a first antenna module 1610 and a second antenna module 1620, but various According to embodiments, the electronic device 101 may include three or more antenna modules. For example, the first antenna module 1610 may be disposed in the first part of the electronic device 101, and the second antenna module 1620 may be disposed in the second part of the electronic device 101. According to various embodiments, the first antenna module 1610 and the second antenna module 1620 may direct different directions, but are not limited thereto. For example, as shown in FIG. 16 , the electronic device 101 may receive signals in all directions through two antenna modules 1610 and 1620 mounted on both sides. Although FIG. 16 shows that the antenna modules 1610 and 1620 are disposed outside the electronic device 101, the antenna modules 1610 and 1620 are disposed outside or inside the housing of the electronic device 101. It could be.

According to various embodiments, the electronic device 101 may set a plurality of reception beams corresponding to the first antenna module 1610 . For example, the electronic device 101 may set a 1-1 reception beam 1611, a 1-2 reception beam 1612, and a 1-3 reception beam 1613 corresponding to the first antenna module 1610. there is. The electronic device 101 may set a plurality of reception beams corresponding to the second antenna module 1620 . For example, the electronic device 101 may set the 2-1 reception beam 1621, the 2-2 reception beam 1622, and the 2-3 reception beam 1623 in correspondence with the second antenna module 1620. there is. Although FIG. 16 and the embodiments described later illustrate that three reception beams are set for each antenna module 1610 and 1620, this is for convenience of explanation and for each antenna module 1610 and 1620 Two or more Rx beams may be configured.

According to various embodiments, the electronic device 101 may receive a first PDSCH from a first TRP 701 and may receive a second PDSCH from a second TRP 702 . For example, the electronic device 101 selects an optimal reception beam for receiving the first PDSCH based on the reception signal strength of a first reference signal (eg, a first CSI-RS) having a QCL relationship with the first PDSCH. can be set 16, it can be assumed that the 1-1st reception beam 1611 corresponding to the first antenna module 1610 is set as the optimum reception beam for receiving the 1st PDSCH. The electronic device 101 may set an optimal reception beam for receiving the second PDSCH based on the reception signal strength of a second reference signal (eg, a second CSI-RS) having a QCL relationship with the second PDSCH. there is. 16, it can be assumed that the 2-1st reception beam 1621 corresponding to the second antenna module 1620 is set as an optimal reception beam for receiving the second PDSCH. According to various embodiments, as a method of setting the optimal reception beam, the electronic device 101 uses a signal to interference plus noise ratio (SINR) for the reference signal (eg, CSI-RS) for each reception beam. , and the reception beam having the largest SINR may be determined as the optimal reception beam.

17 is a diagram illustrating reception beam selection in the NC-JT system according to various embodiments. Referring to FIG. 17 , the electronic device 101 may include a plurality of antenna modules (eg, the third antenna module 246 of FIG. 4 ).

According to various embodiments, the electronic device 101 may set a plurality of reception beams corresponding to the first antenna module 1610 . For example, the electronic device 101 may set a 1-1 reception beam 1611, a 1-2 reception beam 1612, and a 1-3 reception beam 1613 corresponding to the first antenna module 1610. there is. The electronic device 101 may set a plurality of reception beams corresponding to the second antenna module 1620 . For example, the electronic device 101 may set the 2-1 reception beam 1621, the 2-2 reception beam 1622, and the 2-3 reception beam 1623 in correspondence with the second antenna module 1620. there is.

According to various embodiments, the electronic device 101 may receive a first PDSCH from a first TRP 701 and may receive a second PDSCH from a second TRP 702 . For example, the electronic device 101 selects an optimal reception beam for receiving the first PDSCH based on the reception signal strength of a first reference signal (eg, a first CSI-RS) having a QCL relationship with the first PDSCH. can be set In FIG. 17, it can be assumed that the 1-1st reception beam 1611 corresponding to the first antenna module 1610 is set as the optimum reception beam for receiving the 1st PDSCH. The electronic device 101 may set an optimal reception beam for receiving the second PDSCH based on the reception signal strength of a second reference signal (eg, a second CSI-RS) having a QCL relationship with the second PDSCH. there is. In FIG. 17, it can be assumed that the first to third reception beams 1613 corresponding to the first antenna module 1610 are set as optimal reception beams for receiving the second PDSCH. According to various embodiments, as a method of setting the optimal reception beam, the electronic device 101 uses a signal to interferece plus noise ratio (SINR) for the reference signal (eg, CSI-RS) for each reception beam. , and the reception beam having the largest SINR may be determined as the optimal reception beam.

According to various embodiments, as shown in FIG. 17, an optimal reception beam corresponding to a signal (eg, a first PDCCH or a first PDSCH) transmitted by the first TRP 701 and the second TRP 702 ), the optimal reception beams corresponding to the signals (eg, the second PDCCH or the second PDSCH) are different from each other (eg, the first antenna module 1610) corresponding to the same antenna module (eg, the first antenna module 1610). In the case of the -1 RX beam 1611 and the 1-3 RX beams 1613), the electronic device 101 may select any one RX beam as the optimal RX beam. For example, when the received signal strength of each reception beam for each antenna module is determined as shown in Table 2 below, optimal reception beams corresponding to a plurality of TRPs can be determined in the first antenna module.

TRP Rx Beam First antenna module Second antenna module RS 1
(TRP 1) Rx Beam 0 15 dB 1 dB Rx Beam 1 14dB 0.5dB Rx Beam 2 10dB 0.2dB Rx Beam 3 5dB 0.1dB Rx Beam 4 8dB 0.3dB Rx Beam 5 12dB 0.4dB Rx Beam 6 13dB 0.8dB RS 2
(TRP 2) Rx Beam 0 14dB 0.8dB Rx Beam 1 15 dB 0.7dB Rx Beam 2 10dB 0.4dB Rx Beam 3 5dB 0.6dB Rx Beam 4 6dB 0.7dB Rx Beam 5 8dB 0.9dB Rx Beam 6 12dB 1 dB

As another method, a plurality of beams may be simultaneously received for each antenna module by extending the antenna module. In this case, since components of the antenna module including a phase shifter or individual antenna elements for beam forming are additionally required, the size of the antenna module may increase. For example, since the length of a wavelength is 1 cm based on the 29 GHz band, which is a mmWave band, the size of a phase shifter that adjusts the phase through a change in line length is required to change by the size corresponding to the wavelength, and the antenna component is half as well. Since an interval corresponding to a wavelength is required, implementing simultaneous reception with a plurality of beams in an antenna module can increase the size of the antenna module. Accordingly, the antenna module of the electronic device 101 may receive only a specific RX beam due to design restrictions, and may not be able to apply two RX beams at the same time. According to various embodiments, when the electronic device 101 selects one of the optimal reception beams for each of the TRPs 701 and 702, the reception strength of signals transmitted from the remaining TRPs is relatively reduced. Communication performance of the electronic device 101 may decrease. For example, since the time required for beam tracking increases as the number of reception beams used for measurement in the electronic device 101 increases, the number of reception beams actually used in the electronic device 101 may be limited. Due to the characteristics of the FR2 band having strong directivity, the type of reception beam used by the electronic device 101 may be configured as a narrow beam having strong directivity in a specific direction. As described above, when only one reception beam is used in one antenna module due to design restrictions of the electronic device 101, signal strength of different TRPs in NC-JT is used as a narrow beam having strong directivity for the specific direction is used. may decrease.

In various embodiments to be described later, as shown in FIG. 17, when the optimal reception beam for receiving a signal transmitted to each TRP (701, 702) is set in the same antenna module, the set reception beam is changed. By doing so, communication performance can be improved.

18 is a flowchart illustrating a method of operating an electronic device according to various embodiments. Referring to FIG. 18 , according to various embodiments, an electronic device 101 (eg, the processor 120 of FIG. 1 , the first communication processor 212 of FIG. 2A , and the second communication processor 214 of FIG. 2A ) ), or at least one of the unified communication processor 260 of FIG. 2B), in operation 1810, may check information configured for reception of different signals transmitted through a plurality of transmission and reception points (TRPs).

According to various embodiments, whether or not the electronic device 101 has set the NC-JT operation or information set to receive signals through the plurality of TRPs may be included in the RRC message. For example, when multi-DCI-based NC-JT is set, it means that NC-JT can be used if there are CORESETs with two different values (eg, 0 or 1) based on the coresetPoolIndex set in each CORESET. CORESETs with coresetPoolIndex may mean that they are transmitted from different TRPs. According to various embodiments, whether the NC-JT operation is configured or information configured to receive a signal through the plurality of TRPs may be included in an RRC configuration message illustrated in Table 3 below.

According to various embodiments, in operation 1820, the electronic device 101 performs information related to the strength of the received signal corresponding to the first TRP and reception corresponding to the second TRP with respect to a plurality of reception beams set in each of the plurality of antenna modules. Information related to signal strength can be checked. For example, as illustrated in <Table 3> and <Table 4>, when NC-JT is set, the base station may inform the reference signal (eg, CSI-RS) that the electronic device 101 can refer to for each TRP. And, based on the reference signal, the electronic device 101 can select an optimal reception beam for each TRP. For example, as described above, the electronic device 101 may select or set a reception beam having the largest SINR of the reference signal as an optimal reception beam.

According to various embodiments, in operation 1830, the electronic device 101 selects a first reception beam of a first antenna module from among a plurality of antenna modules to receive a signal corresponding to the first TRP, It can be confirmed that the second reception beam of the first antenna module is selected to receive the corresponding signal. For example, as described above with reference to FIG. 17, the electronic device 101 selects a 1-1 reception beam 1611 set corresponding to the first antenna module 1610 to receive a signal corresponding to the first TRP, In order to receive a signal corresponding to the second TRP, first to third reception beams 1613 configured to correspond to the first antenna module 1610 may be selected.

According to various embodiments, when it is determined in operation 1830 that signals corresponding to a plurality of TRPs are received through the same antenna module, the electronic device 101 transmits signals corresponding to the first TRP and second signals in operation 1840. A signal corresponding to the TRP may be simultaneously received through the third reception beam (eg, first to fourth reception beams) of the first antenna module. According to various embodiments, the third RX beam may be different from the 1-1 RX beam 1611 or the 1-3 RX beam 1613 . For example, the third reception beam may correspond to a wider beam having a relatively wider beam width than the 1-1 reception beam 1611 or the 1-3 reception beam 1613 .

19 is a diagram illustrating reception beam selection in the NC-JT system according to various embodiments. Referring to FIG. 19, when the electronic device 101 determines that signals corresponding to a plurality of TRPs are received through the same antenna module (eg, the first antenna module 1610) as described above with reference to FIG. 18 , The signal corresponding to the first TRP and the signal corresponding to the second TRP can be simultaneously received through the first to fourth reception beams 1614 as the third reception beam of the first antenna module. For example, as shown in FIG. 19, the third reception beam (first-four reception beams 1614) is relatively larger than the first-first reception beam 1611 or the first-third reception beam 1613. can correspond to a wide beam having a wide beam width.

In the following description, methods for determining the third Rx beam by the electronic device 101 according to various embodiments will be described.

According to various embodiments, when PDCCHs transmitted from each TRP overlap in time, the electronic device 101 determines a reception beam by considering both the PDCCH and reference signals (eg, two CSI-RSs) connected to QCL for each TRP. can For convenience of description, it can be assumed that X is a reference signal connected to the PDCCH and QCL transmitted from the first TRP 701 and Y is connected to the PDCCH and QCL transmitted from the second TRP 702. It can be assumed that the SINR when the electronic device 101 receives X through reception beam i is SINR(i,X), and the SINR when Y is received through reception beam i is SINR(i,Y) . According to various embodiments, the electronic device 101 calculates the probability of receiving all PDCCHs transmitted from each TRP when using the reception beam i from SINR (i, X) and SINR (i, Y), and maximizes the probability Beam i may be set as the third reception beam. The electronic device 101 simultaneously receives the PDCCH transmitted from the first TRP 701 and the PDCCH transmitted from the second TRP 702 based on the set third Rx beam, thereby increasing the probability of receiving both PDCCHs. . For example, the probability of receiving all PDCCHs transmitted from each TRP may be determined through the mapping table of <Table 5> and <Equation 1>. For example, the SINR and block error rate (BLER) of each reference signal may be stored in a table form as shown in Table 5 below.

SINR(dB) BLER -5 or less 0.1 -5 to -4.5 0.05 ... ... 23.5 to 24 0.001 over 24 0.00001

In Equation 1, BLER_1 represents the expected BLER for the first PDCCH transmitted from the first TRP 701, and BLER_2 represents the expected BLER for the second PDCCH transmitted from the second TRP 702. The electronic device 101 calculates a PDCCH reception probability based on Equation 1 for a plurality of reception beams configured in the first antenna module 1610, and selects a reception beam having the highest PDCCH reception probability as the first reception beam. It can be set to 3 receive beams. For example, since the probability of receiving the PDCCH is reduced in a TRP having a low SINR, the probability of receiving the PDCCH on both sides may be reduced. When the Rx beam is set based on Equation 1, it is advantageous to receive all of the plurality of PDCCHs because the SINR can be uniformly high in a plurality of TRPs.

According to various embodiments, Table 6 below describes an example of determining the third Rx beam through the SINR measured in the actual electronic device 101.

SINR 1st reference signal
(1st CSI-RS) Second reference signal
(Second CSI-RS) Expected BLER 1-1 receive beam 15dB 3dB 5% 1-2 receive beam 7dB 7dB 5% 1-3 receive beam 3dB 15dB 3% 1-4 receive beam 10dB 10dB One%

Referring to Table 6, in order to receive the 1st PDCCH transmitted from the 1st TRP 701, the 1-1 Rx beam can be set as the optimal Rx beam and transmitted from the 2nd TRP 702 In order to receive the second PDCCH, reception beams 1-3 may be set as optimal reception beams. However, when the first PDCCH and the second PDCCH are simultaneously received, one first antenna module 1610 transmits the 1-1 Rx beam 1611 and the 1-3 Rx beam 1613 at the same time. Since it cannot be formed, the reception probability of the PDCCH can be increased by forming the first to fourth reception beams 1614 according to various embodiments.

According to various embodiments, the electronic device 2020 may check whether PDCCHs transmitted from each of a plurality of TRPs overlap in time. For example, it can be checked whether the first PDCCH transmitted from the first TRP 701 and the second PDCCH transmitted from the second TRP 702 overlap in time. When it is determined in operation 2020 that the PDCCHs of the plurality of TRPs overlap in time (operation 2020-yes), the electronic device 101 may identify a reception beam for simultaneously receiving signals received from the plurality of TRPs in operation 2030. there is.

The operation of confirming that signals transmitted from the plurality of TRPs are received by the same antenna module may be performed by the method described above with reference to FIG. 19 .

According to various embodiments, the electronic device 101 may check whether a default QCL is selected in operation 2120 . For example, as described above, when a scheduling time offset set in a PDSCH scheduled by NC-JT is smaller than timeDurationForQCL, the Rx beam may be set according to the default QCL. According to various embodiments, in operation 2130, the electronic device 101 may check whether the default QCL indicates setting of a reference signal for each TRP. As a result of the check, if the default QCL indicates the setting of the reference signal for each TRP (operation 2130 - Yes), the electronic device 101 transmits the signal received from each TRP in operation 2150 to the third reception beam of the first antenna module. can be received based on A method of setting the third reception beam in the electronic device 101 may use the method of FIGS. 18 and 19 described above.

According to various embodiments, as a result of checking in operation 2130, if the default QCL does not indicate setting of a reference signal for each TRP (operation 2130 - No), the electronic device 101 selects one connected to the default QCL in operation 2140. A reception beam may be selected based on the reference signal. According to various embodiments, when it is confirmed that the default QCL is not selected as a result of checking in operation 2120 (operation 2120 - No), the electronic device 101 transmits signals received from each TRP to a first antenna in operation 2150. It can be simultaneously received through the third receive beam of the module. A method of setting the third reception beam in the electronic device 101 may use the method of FIGS. 18 and 19 described above. For example, when a scheduling time offset set in a PDSCH scheduled with NC-JT exceeds timeDurationForQCL, a reference signal (eg, CSI-RS) can be checked for each TRP according to a TCI set in DCI. The electronic device 101 may determine the third reception beam based on the reference signal for each TRP identified above.

For example, for convenience of description, it can be assumed that the reference signal connected to the PDSCH and QCL transmitted from the first TRP 701 is X, and the reference signal connected to the PDSCH and QCL transmitted from the second TRP 702 is Y. . The electronic device 101 assumes that the SINR when X is received through RX beam i is SINR (i, X), and the SINR when Y is received through RX beam i is SINR (i, Y). there is.

The electronic device 101 can simultaneously receive the PDSCH transmitted from the first TRP 701 and the PDSCH transmitted from the second TRP 702 based on the configured third Rx beam to increase the reception capacity of the PDSCHs. For example, the receivable capacity of PDSCHs transmitted from each TRP may be determined through a mapping table in Table 7 below. For example, the SINR and spectral efficiency of each reference signal may be stored in a table form as shown in Table 7 below.

SINR(dB) spectral efficiency -5 or less 0.3964 -5 to -4.5 0.4381 ... ... 23.5 to 24 7.813 over 24 7.9784

In this case, since the optimal reception beam for the corresponding reference signal is used, a new beam may not be changed. For example, the electronic device 101 may continuously use the reception beam used in the lowest index CORESET (lowest CORESET) monitored in the latest slot. For example, referring to FIG. 22, QCL is assigned to CORESET #1 (2210), which is a CORESET having a lower index among CORESET #1 (2210) and CORESET #2 (2220) connected to search spaces (2211 and 2221) set in the latest slot.
