One block shown in Figure 3 represents one slot, 'D' in the block indicates that downlink reception is performed in the slot, 'U' indicates that uplink transmission is performed in the slot, and 'S ' may indicate that the slot corresponds to a special subframe.

For example, a special subframe may have 9 predetermined formats. Each subframe consists of 14 symbols, and a special subframe can be used for uplink transmission of up to 2 symbols depending on the format.

In NR, uplink transmission and downlink reception can be changed on a symbol basis, and the slot format can be as shown in FIG. 3. For example, when SCS (sub carrier spacing) is 30kHz, one slot is 0.5ms and can be composed of 14 symbols. Generally, one cycle includes 5 slots (e.g., 2.5 ms) and may be composed of slots in the order [D, D, D, S, U], for example. Here, 'D' may represent a slot in which downlink reception is performed, 'S' may represent a slot corresponding to a special subframe, and 'U' may represent a slot in which uplink transmission is performed.

For example, a slot performing downlink reception has a format in which all 14 symbols perform downlink reception, and a slot performing uplink transmission has a format in which all 14 symbols perform uplink transmission. A slot corresponding to a special subframe may have a format including 10 downlink reception symbols, 2 uplink transmission symbols, and 2 flexible symbols.

As explained earlier, because the definition of the slot format between LTE and NR is different, uplink transmission and downlink reception occur at the same time in TDD-TDD ENDC that performs communication using LTE and NR simultaneously, which can cause interference with each other. You can.

If NR includes [D, D, D, S, U] slots with a period of 2.5ms, synchronization between LTE slot format and NR slot format will result in LTE and NR for one frame (e.g. 10ms). The uplink/downlink configuration may be as shown in FIG. 3.

Depending on the slot format of LTE, the slot in which NR downlink reception is performed and the slot in which LTE uplink transmission is performed are placed simultaneously, or the slot in which NR uplink transmission is performed and the slot in which LTE downlink reception is performed These can be placed simultaneously. For convenience of explanation, in this specification, a slot in which downlink reception is performed is referred to as a downlink slot, a slot in which uplink transmission is performed is referred to as an uplink slot, and a slot corresponding to a special subframe is referred to as a special slot. It can be referred to.

When LTE's uplink slot and NR's downlink slot are placed simultaneously, or LTE's downlink slot and NR's uplink slot are placed simultaneously, it can be identified as a target slot where interference is expected to occur, and is used in this case. If the LTE antenna and the NR antenna are adjacent to each other, the uplink signal may flow into the downlink antenna, causing interference, and downlink throughput may be reduced.

FIG. 4 is a diagram illustrating antennas within an electronic device according to an embodiment.

Referring to FIG. 4 , the electronic device 400 (e.g., the electronic device 101 of FIG. 1 ) may include first to fifteenth antennas 401 to 415 . However, the number or arrangement of antennas included in the electronic device 400 is not limited to those shown in FIG. 4, and various other antenna numbers or arrangements may be applied without limitation.

In the example shown in FIG. 4, the first antenna 401 is a first main antenna implemented as part of a frame (e.g., metal frame) of the electronic device 400, and communicates in the LTE low/middle band. can be performed. The second antenna 402 is a second main antenna implemented as part of a frame (e.g., metal frame) of the electronic device 400 and is capable of performing communication in the LTE high band, and B41 uses LTE band 41. Indicated, it can operate as a transmitting antenna (TX) or a first primary receiving antenna (PRX1). The third antenna 403 is a third main antenna implemented as part of a frame (e.g., metal frame) of the electronic device 400, and is capable of performing communication in the NR high band. n78 indicates NR band 78, and n78 represents the NR band 78. 1 It can operate as a diversity receiving antenna (DRX1). The frames used for the first antenna 401, the second antenna 402, and the third antenna 403 can be divided into segmented parts, and this can also be applied to antennas using other frames.

The fourth antenna 404 is a fourth main antenna implemented as a SUS plate (stainless steel plate) disposed in the electronic device 400, and is capable of performing communication in the NR middle band, and is an n78 second diversity receiving antenna ( DRX2) or B41 second primary antenna (PRX2). The fifth antenna 405 is a fifth main antenna implemented as a laser direct structuring (LDS) antenna in the electronic device 400 and can perform communication through the NR band. The fifth antenna 405 may be selectively placed in the electronic device 400.

The sixth antenna 406 is a first sub-antenna implemented as part of the frame of the electronic device 400, is capable of performing communication in LTE low/middle/high bands, and operates as the B41 first diversity receiving antenna (DRX1). can do. The seventh antenna 407 is a second sub-antenna implemented as part of the frame of the electronic device 400, and may operate as an n78 transmitting antenna (TX) or a first primary receiving antenna (PRX1). The eighth antenna 408 is a third sub-antenna implemented as part of the frame of the electronic device 400 and can operate as an ultra-wideband (UWB) antenna. The ninth antenna 409 is a fourth sub-antenna implemented as part of the frame of the electronic device 400, and can perform communication using the L5 or first WiFi signal. The tenth antenna 410 is a fifth sub-antenna implemented as part of the frame of the electronic device 400 and can perform communication in the NR band. The 11th antenna 411 is a fifth sub-antenna implemented as part of the frame of the electronic device 400, is capable of performing communication in LTE L1/middle/high band, and operates as the B41 second diversity receiving antenna (DRX2). can do. The twelfth antenna 412 is a seventh sub-antenna implemented as an LDS antenna and can perform communication using a second WiFi signal. The 13th antenna 413 is an 8th sub-antenna implemented as an LDS antenna and can be selectively placed in the electronic device 400. The fourteenth antenna 414 is a ninth sub-antenna implemented as a flexible printed circuit board (FPCB) radio frequency (RF) cable antenna (FRC antenna), and may be selectively placed in the electronic device 400. The fifteenth antenna 415 may operate as a UWB antenna.

The TDD-TDD ENDC combination applied to the electronic device 400 may be, for example, B38-n78, B40-n78, B41-n78, or B40-n40, and various other combinations may be applied without limitation.

In the example shown in FIG. 4, when B41 (2x2 MIMO)-n78 (4x4 MIMO) ENDC is activated, the uplink signal of the second antenna 402 is transmitted to the third antenna at the LTE uplink and NR downlink timing. Due to abandonment at (403), n78 downlink throughput may be reduced. Additionally, the uplink signal of the seventh antenna 407 may be transferred to the sixth antenna 406 at the NR uplink and LTE downlink timings, resulting in a decrease in B41 downlink throughput.

FIG. 5 is a diagram illustrating an operation of identifying a target slot where interference is expected to occur according to an embodiment.

Referring to FIG. 5, an example of LTE slot format #2 and NR slot format being used for TDD-TDD ENDC is shown.

In NR, one frame (e.g. 20 slots) may include 12 downlink slots, 4 uplink slots, and 4 special slots, where the special slots include 10 downlink symbols, 2 flexible symbols, and uplink symbols. Since it actually operates as a downlink with two link symbols, one frame of NR can be considered to include 16 downlink slots and 4 uplink slots.

In the case of LTE slot format #2 and NR slot format shown as an example in FIG. 5, interference occurs in 2 slots 510 out of 16 NR downlink slots, and in 2 slots 510 out of 16 LTE downlink slots ( 520), interference may occur. In FIG. 5, for convenience of explanation, the description is based on LTE slot format #2, but if a different LTE slot format is used, the slot in which interference occurs may be different.

When TDD-TDD ENDC is activated and a communication band is established, target antennas used for LTE and NR communication can be identified, and if the target antennas are adjacent to each other, it can be determined that they may cause interference with each other. Additionally, it can be predicted in which slot the downlink BLER (block error ratio) of LTE/NR occurs depending on the LTE/NR slot format. As described above, a slot in which uplink transmission and downlink reception are performed simultaneously may be identified as a target slot where interference is expected to occur. In the example shown in FIG. 5, slots 510 and 520 may be identified as target slots.

Different antenna control from other slots may be performed to suppress interference from occurring in the target slot. For example, interference can be avoided in the target slot by applying AIT (antenna impedance tuning) that is different from other slots to the target slot, or by changing the antenna performing communication in the target slot to be different from other slots. You can. Antenna switching may include a receive path swap (RX path swap) operation.

First, the operation to suppress interference in the target slot by changing the AIT will be explained. AIT tunes the antenna impedance, and basically operates as a default AIT appropriate for the TDD-TDD ENDC combination. By changing the AIT only in the target slot, downlink throughput degradation that occurs in the target slot can be prevented.

In the example shown in FIG. 5, in order to suppress NR downlink throughput degradation due to the LTE uplink signal that may occur in the two slots 510, the default AIT is connected to the second antenna (e.g., the second antenna 402 in FIG. 4). )) and the third antenna (e.g., the third antenna 403 in FIG. 4) can be changed to AIT that maximizes the isolation. In addition, the NR uplink signal that can occur in the two slots 520 To suppress LTE downlink throughput degradation, the default AIT maximizes the isolation between the sixth antenna (e.g., the sixth antenna 406 in FIG. 4) and the seventh antenna (e.g., the seventh antenna 407 in FIG. 4). The default AIT can be applied to other slots except for the four slots 510 and 520 described above.

Since the tuner and switch for changing the AIT can operate in microseconds, the AIT can be changed in slot units (e.g., 0.5 ms) as described above.

In some cases, isolation between target antennas may not be secured due to AIT change, and in this case, interference can be avoided in the target slot through antenna switching, which will be described in detail with reference to the drawings below.

Figures 6 and 7 are diagrams for explaining antenna change when each of a plurality of network communications operates in 4x4 MIMO according to an embodiment.

Referring to FIG. 6, an example is shown to explain an antenna switching operation to suppress NR downlink throughput degradation due to an LTE uplink signal in an LTE 4x4 MIMO and NR 4x4 MIMO based communication environment. For example, FIG. 6 shows that the LTE uplink signal from the second main antenna 610 (e.g., the second antenna 402 of FIG. 4) is transmitted to the third main antenna 630 (e.g., the third antenna 402 of FIG. 4). Switching operation for the LTE transmission antenna is shown when interference occurs in the NR downlink signal at the antenna 403).

NR downlink interference caused by LTE uplink can be resolved by changing the LTE transmission path through a sounding reference signal switching circuit (SRS switching circuit). Basically, the NR TDD band can be configured with a circuit so that the transmit antenna can be switched to four receive paths for SRS switching. Since the LTE band B41 shares a circuit with the NR band n41, the transmission antenna of B41 can also be switched through the SRS switching circuit without adding additional hardware.

The second main antenna 610 used for LTE uplink transmission may be switched to an antenna that is spaced apart from the NR reception antenna by a preset distance or more. If there are multiple antennas that are separated from the current antenna that is the switching target by a preset distance or more, the antenna to be switched may be selected based on signal quality information for the plurality of antennas. The signal quality information may include information about at least one of reference signals received power (RSRP), received signal strength indicator (RSSI), and signal-to-noise ratio (SNR), but is not limited to the above-described example. For example, if the user's body touches the antenna that is furthest from the current antenna and the signal quality of that antenna is worse than that of another antenna, the current antenna may be switched to the other antenna. Additionally, the preset distance is a distance that can ensure isolation between two antennas, and may vary depending on the type of antenna. For example, when the correlation between two antennas is measured above a certain absolute value (e.g., 35 dB), isolation between the two antennas can be established as secured, and the distance at which isolation between the two antennas is secured can be set in advance. there is.

In the example of FIG. 6, the second main antenna 610 may be switched to a sixth sub-antenna 620 (e.g., the 11th antenna 411 in FIG. 4) that is spaced apart from the NR receiving antenna by a preset distance or more. Through this, n78 downlink interference caused by the B41 uplink can be reduced or eliminated.

Referring to FIG. 7, an example is shown to explain an antenna switching operation to suppress LTE downlink throughput degradation due to an NR uplink signal in an LTE 4x4 MIMO and NR 4x4 MIMO based communication environment. For example, FIG. 7 shows that the first sub-antenna 730 (e.g., the 6th antenna 407 in FIG. 4) is transmitted by the NR uplink signal from the second sub-antenna 710 (e.g., the 7th antenna 407 in FIG. 4). It shows a switching operation for the NR transmit antenna when interference occurs in the LTE downlink signal at the antenna 406.

LTE downlink interference caused by the NR uplink can also be resolved by changing the NR transmission path through the SRS switching circuit in the NR TDD band. The second sub-antenna 710 used for NR uplink transmission may be switched to an antenna that is spaced apart from the LTE reception antenna by a preset distance or more. In the example of FIG. 7, the LTE reception antenna includes a first sub-antenna 730, a sixth sub-antenna 740 (e.g., the 11th antenna 411 in FIG. 4 and the sixth sub-antenna 620 in FIG. 6), A second main antenna 750 (e.g., the second antenna 402 in FIG. 4 and the second main antenna 610 in FIG. 6), a fourth main antenna 760 (e.g., the fourth antenna 404 in FIG. 4 )), and the second sub-antenna 710 may be switched to the ninth sub-antenna 720 (e.g., the 14th antenna 414 in FIG. 4) that is spaced apart from the LTE reception antenna by a preset distance or more. Through this, B41 downlink interference caused by n78 uplink can be reduced or eliminated.

For example, if the LTE slot format and the NR slot format are the same as shown in FIG. 5, in the two slots 510 where NR downlink interference due to the LTE uplink is expected to occur, the second main antenna (2) described in FIG. 6 610) can be switched to the sixth sub-antenna 620, and in the two slots 520 where LTE downlink interference by the NR uplink is expected to occur, the second sub-antenna 710 described in FIG. 7 is the 9th sub-antenna 620. It can be switched to the sub-antenna 720. In the remaining slots except for the four slots 510 and 520, communication can be performed by using the original antenna as is.

FIG. 8 is a diagram illustrating an antenna change when one of a plurality of network communications operates in 2x2 MIMO according to an embodiment.

In the case where NR downlink interference occurs due to LTE uplink in an LTE 2x2 MIMO and NR 4x4 MIMO based communication environment, the antenna switching operation described in FIG. 6 can be applied as is, so detailed description is omitted.

Referring to FIG. 8, an example is shown to explain an antenna switching operation to suppress LTE downlink throughput degradation due to an NR uplink signal in an LTE 2x2 MIMO and NR 4x4 MIMO based communication environment. For example, FIG. 8 shows the first sub-antenna by the NR uplink signal from the second sub-antenna 840 (e.g., the seventh antenna 407 in FIG. 4 and the second sub-antenna 710 in FIG. 7). Indicates a switching operation for the LTE reception antenna when interference occurs in the LTE downlink signal at 810 (e.g., the sixth antenna 406 in FIG. 4 and the first sub-antenna 730 in FIG. 7). In FIG. 8, the first sub-antenna 810 and the second main antenna 850 (e.g., the second antenna 402 in FIG. 4, the second main antenna 610 in FIG. 6, and the second main antenna in FIG. 7 ( 750)) can be used in LTE 2x2 MIMO.

If LTE communication supports four reception bands, interference can be reduced or eliminated by switching the currently used LTE reception antenna to another LTE reception antenna instead of the NR transmission antenna. Since all four NR transmit antennas are utilized with NR 4x4 MIMO-based communication, switching the LTE receive antenna instead of the NR transmit antenna may be more effective.

The first sub-antenna 810 used for LTE downlink reception may be switched to an antenna that is spaced apart from the NR transmission antenna by a preset distance or more. In the example of FIG. 8, the first sub-antenna 810 is a sixth sub-antenna 820 (e.g., the 11th antenna 411 in FIG. 4 and the 6th sub-antenna 411 in FIG. 7) that is spaced apart from the NR transmission antenna by a preset distance or more. antenna 740) or the fourth main antenna 830 (e.g., the fourth antenna 404 in FIG. 4 and the fourth main antenna 760 in FIG. 7), through which the n78 uplink B41 Downlink interference can be reduced or eliminated.

For example, if the LTE slot format and the NR slot format are the same as shown in FIG. 5, in the two slots 510 where NR downlink interference due to the LTE uplink is expected to occur, the second main antenna (2) described in FIG. 6 610) can be switched to the sixth sub-antenna 620, and in the two slots 520 where LTE downlink interference by the NR uplink is expected to occur, the first sub-antenna 810 described in FIG. 8 is switched to the sixth sub-antenna 620. It may be switched to the sub-antenna 820 or the fourth main antenna 830. In the remaining slots except for the four slots 510 and 520, communication can be performed by using the original antenna as is.

FIG. 9 is a diagram illustrating an operation of identifying a target slot when TDD synchronization between a plurality of network communications is lost according to an embodiment.

Referring to FIG. 9, an example is shown to explain the operation of identifying a target slot according to propagation delay occurring in each of LTE communication and NR communication.

Generally, in a wireless communication environment, a propagation delay occurs between a base station and an electronic device (e.g., the electronic device 101 in FIG. 1 and the electronic device 400 in FIG. 4), and NR communication uses a higher frequency than LTE communication. Therefore, because the path loss is large, longer delays may occur. Propagation delay can be partially resolved with a guard period within a special subframe, but in situations where the downlink continues for several slots, additional interference may occur due to propagation delay.

The electronic device can check the delay between the base station and the electronic device in advance through timing advance transmitted from the base station. The electronic device can determine the degree of TDD sync deviation by comparing the timing advance of each of LTE and NR.

For example, if it is determined that the TDD sync is out of sync by one slot time based on the timing advance, additional overlapping slots (e.g. slots 6, 10, 16, and 20) are added to the slots where interference is expected to occur. : Slots 5, 11, 15, and 1) can be determined as the target slot. In the example shown in FIG. 9, slots 6 and 16 may appear to correspond to both LTE and NR uplink slots due to TDD synchronization, but since the delay may not occur by exactly one slot, the existing Slots where interference is expected to occur may be included in the target slot by default. In summary, in the example of FIG. 9, eight slots 910 and 920 can be identified as target slots.

For the target slot, downlink throughput degradation that may occur in the slot can be prevented by changing the AIT or antenna switching described above.

Figure 10 is a diagram for explaining an operation to improve BLER during TDD-TDD ENDC operation according to an embodiment.

In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. Operations 1010 to 1090 involve at least one component (e.g., processor 120 of FIG. 1) of an electronic device (e.g., electronic device 101 of FIG. 1 and electronic device 400 of FIG. 4). It can be performed by .

In operation 1010, the electronic device may activate dual connectivity using multiple network communications. For example, an electronic device can activate TDD-TDD ENDC, which performs communication using LTE and NR simultaneously.

In operation 1020, the electronic device may identify a nearby antenna that may cause interference between the transmit antenna and the receive antenna. When TDD-TDD ENDC is activated and a communication band is set, the electronic device can identify target antennas used for LTE and NR communication. The electronic device can determine whether target antennas are adjacent and may cause interference with each other. For example, the electronic device may determine that interference between target antennas may occur when the distance between target antennas is less than a predetermined threshold. Alternatively, the electronic device may determine whether the target antennas may cause interference with each other based on information about whether the target antennas are adjacent and may cause interference with each other. The information may be pre-stored in the internal storage device of the electronic device or received from an external storage device of the electronic device, but is not limited to the above-described examples.

Operation 1030 may be subsequently performed in response to a case where it is determined that the target antennas may interfere with each other. Conversely, when it is determined that the target antennas do not cause interference with each other, the operation of the electronic device may be completed in response.

In operation 1030, the electronic device may identify a target slot where interference is expected to occur according to the LTE and NR slot format. For example, the electronic device may identify a slot in which uplink transmission based on one network communication and downlink reception based on another network communication are simultaneously performed as the target slot.

In operation 1040, the electronic device determines the degree of deviation of the TDD sync between LTE communication and NR communication according to the propagation delay occurring in each of the LTE communication and NR communication, and determines the degree to which additional interference is expected to occur depending on the degree of deviation of the TDD sync. A slot can be identified as a target slot. Operation 1040 may be performed selectively and may be omitted depending on the embodiment.

In operation 1050, the electronic device may determine whether isolation between target antennas can be secured by changing the AIT in the target slot. For example, the electronic device may determine whether isolation between the target antennas can be secured by changing the AIT in the target slot based on the arrangement between the target antennas and/or the downlink/uplink combination of network communication. Alternatively, the electronic device may determine whether isolation can be secured based on information about whether isolation between target antennas can be secured by changing the AIT. The information may be pre-stored in the internal storage device of the electronic device or received from an external storage device of the electronic device, but is not limited to the above-described examples.

If isolation between target antennas can be secured by changing the AIT, operation 1060 may be performed subsequently. Otherwise, operation 1070 may be performed subsequently.

In operation 1060, the electronic device may control the impedance of the target antennas in the target slot to be different from that in other slots. The electronic device can temporarily change to an AIT that maximizes the isolation of target antennas in the target slot.

In operation 1070, the electronic device may determine whether 4x4 MIMO is applied to each of a plurality of network communications. By taking advantage of the fact that 4x4 MIMO is mostly applied to NR communication, the electronic device may only determine whether 4x4 MIMO is applied to LTE communication.

If 4x4 MIMO is applied to LTE communication, operation 1080 may be performed subsequently, otherwise operation 1090 may be performed subsequently.

At operation 1080, in response to an interference with downlink reception based on the second network communication due to uplink transmission based on the first network communication in the destination slot, the electronic device may transmit the uplink transmission based on the first network communication. The reference antenna used can be changed to an antenna that is spaced apart by a preset distance or more from the antenna used for downlink reception of the second network communication. This operation can be applied to both NR downlink interference by LTE uplink and LTE downlink interference by NR uplink.

Operation 1090 may correspond to a case where 2x2 MIMO is applied to LTE communication. In operation 1090, the electronic device may perform LTE transmission or reception antenna switching in the target slot. For example, in response to a case where interference occurs in downlink reception based on NR communication due to uplink transmission based on LTE communication in the target slot, the electronic device switches the reference antenna used for uplink transmission of LTE communication to the NR communication. It can be changed to an antenna that is separated from the antenna used for downlink reception by more than a preset distance. In addition, the electronic device responds when interference occurs in downlink reception based on LTE communication due to uplink transmission based on NR communication in the target slot, and connects the reference antenna used for downlink reception of LTE communication to the uplink reception of NR communication. It can be changed to an antenna that is separated from the antenna used for link transmission by a preset distance or more.

The electronic device determines whether target antennas used for multiple network communications may cause interference with each other by checking the TDD-TDD ENDC combination, identifies target slots where interference is expected to occur according to the slot format, and provides timing advance. By checking and predicting electronic delay and identifying additional target slots, AIT change or antenna switching based on band combination or MIMO rank is performed in real time according to the situation to receive downlink by uplink transmission in TDD-TDD ENDC Throughput degradation can be minimized.

According to one embodiment, in the electronic device 1100, the processor 1120 applies 4x4 MIMO to each of a plurality of network communications, and transmits the second network due to uplink transmission based on the antenna used for the first network communication in the target slot.
