DETAILED DESCRIPTION

[0179] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0180] (Implementation Method 1)

[0181] In the first embodiment, a communication system, a communication device, and a communication method are described.

[0182] Figure 1A An example of the structure of communication devices such as base stations, access points, terminals, repeaters, gNB (gNode B), UE (User Equipment), and TRP (Transmission / Reception Point) in this embodiment is shown.

[0183] In the following, we will use the NR (New Radio) wireless system as an example. The NR wireless system, for example, includes base stations and terminals. NR base stations can be referred to as gNBs. NR terminals can be referred to as UEs. However, these names are not limited to these. Below, NR terminals may sometimes be referred to as "NR-UEs."

[0184] Set as, Figure 1A The communication device includes N transmitting units, namely, "a first transmitting unit 102_1 to an Nth transmitting unit 102_N." In addition, N is an integer greater than or equal to 1 or an integer greater than or equal to 2.

[0185] In addition, let Figure 1A The communication device includes M transmission panel antennas for transmission, namely, "transmission panel antenna 1 of 106_1 to transmission panel antenna M of 106_M." In addition, M is an integer greater than or equal to 1 or an integer greater than or equal to 2.

[0186] Set as, Figure 1A The communication device includes n receiving units, namely, "a first receiving unit 155_1 to an n-th receiving unit 155_n." In addition, n is an integer greater than or equal to 1 or an integer greater than or equal to 2.

[0187] Set as, Figure 1A The communication device includes m receiving panel antennas for reception, namely, "receiving panel antenna 1 of 151_1 to receiving panel antenna m of 151_m." Note that m is an integer greater than or equal to 1 or an integer greater than or equal to 2.

[0188] The i-th transmitter 102_i receives the control signal 100 and the i-th data 101_i as input, performs processing such as error correction coding and mapping based on the modulation scheme, and outputs the i-th modulated signal 103_i.

[0189] Furthermore, the i-th data 101_i may include data of more than one user. In this case, an error correction code, modulation method, and transmission method may be set for each user.

[0190] The first processing unit 104 receives as input an i-th modulated signal 103_i (i is an integer from 1 to N), the control signal 100, and the reference signal 199, and outputs a j-th transmit signal 105_j (j is an integer from 1 to M) based on the frame structure information included in the control signal 100. The i-th modulated signal 103_i may contain a modulation signal with no signal, and the j-th transmit signal 105_j may contain a transmit signal with no signal.

[0191] Next, the jth transmission signal 105_j is output as a radio wave from the transmission panel antenna j of 106_j. Furthermore, the transmission panel antenna j of 106_j can also receive the control signal 100 as input and perform beamforming to change the transmission directionality. Furthermore, the transmission panel antenna j of 106_j can also be switched based on the control signal 100 when transmitting a modulated signal to the communication partner. This will be described later.

[0192] The i-th received signal 152_i is received by the receiving panel antenna i of 151_i. In addition, the receiving panel antenna i of 151_i can also use the control signal 100 as input to perform beamforming to change the receiving directivity. This will be described later.

[0193] The second processing unit 153 receives the i-th received signal 152_i and the control signal 100 as input, performs frequency conversion and other processing, and outputs the j-th signal-processed signal 154_j. Note that the i-th received signal 152_i may contain a non-signal received signal, and the j-th signal-processed signal 154_j may contain a non-signal processed signal.

[0194] The jth receiving unit 155_j receives the jth signal-processed signal 154_j and the control signal 100 as input, performs demodulation and error correction decoding on the jth signal-processed signal 154_j based on the control signal 100, and outputs jth control data 156_j and jth data 157_j.

[0195] Furthermore, the j-th control data 156_j may include control data for one or more users, and the j-th data 157_j may include data for one or more users.

[0196] The third processing unit 158 ​​receives the j-th control data 156_j as input, generates and outputs the control signal 100 based on information obtained from the communication partner, etc.

[0197] also, Figure 1A The first processing unit 104 of the communication device may also perform processing for transmit beamforming (transmit directivity control), such as precoding processing. Furthermore, the second processing unit 153 may also perform processing for receive directivity control. As another example, the first processing unit 104 may also perform processing such that the first transmit signal 105_1 is output as the first modulated signal 103_1, the second transmit signal 105_2 is output as the second modulated signal 103_2, and the third transmit signal 105_3 is output as the third modulated signal 103_3. Alternatively, the first processing unit 104 may also perform processing such that the first transmit signal 105_1 is output as the second modulated signal 103_2. Alternatively, the second processing unit 153 may perform processing such that the first signal-processed signal 154_1 becomes the first received signal 152_1, the second signal-processed signal 154_2 becomes the second received signal 152_2, and the third signal-processed signal 154_3 becomes the third received signal 152_3. Alternatively, the second processing unit 153 may perform processing such that the second signal-processed signal 154_2 becomes the first received signal 152_1.

In addition, it can also be, Figure 1A (and Figure 1B 、 Figure 1C ) uses a first frequency (frequency band) to perform multi-user MIMO transmission that supports sending modulated signals to multiple terminals in at least a first time interval.

Figure 1B In the Figure 1A The same reference numerals are assigned to parts that perform the same operations, and detailed descriptions thereof are omitted.

[0200] Figure 1B The characteristic feature of the 105_x transmission scheme is that the number of transmitting units is equal to the number of transmitting panel antennas. In this case, the first processing unit 104 can perform processing for transmit beamforming (transmit directivity control), such as precoding. Furthermore, the first processing unit 104 can output the xth transmit signal 105_x as the yth modulated signal 103_y. Note that x is an integer greater than or equal to 1 and less than or equal to M, and y is an integer greater than or equal to 1 and less than or equal to M.

[0201] Furthermore, the number of receiving units is assumed to be the same as the number of receiving panel antennas. In this case, the second processing unit 153 may also perform processing for receiving directivity control. Alternatively, the second processing unit 153 may output the x-th processed signal 154_x as the y-th received signal 152_y. Here, x is an integer greater than or equal to 1 and less than or equal to m, and y is an integer greater than or equal to 1 and less than or equal to m.

In addition, the number of receiving units is the same as the number of receiving panel antennas, and there is no second processing unit.

[0204] in addition, Figure 1A 、 Figure 1B 、 Figure 1C These are examples of the structures of communication devices such as base stations, access points, terminals, repeaters, and TRPs, but the methods of constructing communication devices are not limited to the above examples.

Data 201 corresponds to i-th data 101_i, and control signal 200 corresponds to control signal 100. Therefore, data 201 may include data for more than one user.

[0207] Reference signal generation unit 204 receives control signal 200 as input and generates and outputs reference signal 205 based on the frame structure information included in control signal 200. Reference signal 205 is a signal transmitted to determine the transmit beam and / or receive beam, transmission method, reception method, etc. used for communication with the communication partner, and to implement various noise estimation and channel estimation.

[0208] Another signal generating unit 206 receives the control signal 200 as input, generates and outputs another signal 207 based on the control signal.

[0209] Processing unit 251 receives as input the modulated signal 203 of the data symbol, the reference signal 205, the other signal 207, and the control signal 200. Based on the frame structure information included in the control signal 200, it generates and outputs a modulated signal 252 that conforms to the frame structure. Furthermore, modulated signal 252 that conforms to the frame structure corresponds to the i-th modulated signal 103_i. A specific example of the frame structure will be described in detail later.

In addition, i is an integer greater than or equal to 1 and less than or equal to M. The distribution unit 302 receives the transmission signal 301 as input, distributes it, and outputs the first transmission signal 303_1, the second transmission signal 303_2, the third transmission signal 303_3, and the fourth transmission signal 303_4. In addition, the transmission signal 301 corresponds to “ Figure 1A 、 Figure 1B The i-th transmission signal 105_i" or " Figure 1C The i-th modulated signal 103_i".

Next, antenna 306_1 outputs first transmit signal 305_1 multiplied by the coefficient as a radio wave. Control signal 300 corresponds to control signal 100.

[0212] Let's explain this in detail. Let's express first transmitted signal 303_1 as tx1(t). Here, t is time. Furthermore, if the multiplication coefficient is w1, then first transmitted signal 305_1 multiplied by the coefficient can be expressed as tx1(t) × w1. Furthermore, tx1(t) can be represented by a complex number, so it can also be a real number. Furthermore, w1 can be represented by a complex number, so it can also be a real number.

Furthermore, tx4(t) can be represented by a complex number, so it can also be a real number. Furthermore, w4 can also be represented by a complex number, so it can also be a real number.

[0219] Alternatively, the absolute values ​​of w1, w2, w3, and w4 may be equal. This is equivalent to a phase change. Of course, the absolute values ​​of w1, w2, w3, and w4 may not be equal.

[0220] The values ​​of w1, w2, w3, and w4 can be switched per frame, per slot, per mini-slot, per multiple symbols, or per symbol. The timing of switching the values ​​of w1, w2, w3, and w4 is not limited to the above examples.

[0231] Let's explain this in more detail. Let's express fourth received signal 402_4 as rx4(t). Here, t is time. Furthermore, if the multiplication coefficient is d4, then the fourth received signal 404_4 multiplied by the coefficient can be expressed as rx4(t) × d4. Furthermore, since rx4(t) can be represented by a complex number, it can also be a real number. Furthermore, since d4 can also be represented by a complex number, it can also be a real number.

In addition, other processing units may also exist in the receiving device.

[0253] In the above description, examples of the configuration of a single-carrier reception method and a reception apparatus have been described, but examples of the single-carrier reception method and the reception apparatus are not limited thereto. For example, examples of single-carrier methods include "DFT (Discrete Fourier Transform)-Spread OFDM (Orthogonal Frequency Division Multiplexing)" (DFT-S OFDM), "Trajectory Constrained DFT-Spread OFDM", "Constrained DFT-Spread OFDM" (Constrained DFT-S OFDM), "OFDM based SC (Single Carrier)", "SC (Single Carrier)-FDMA (Frequency Division Multiple Access)", "Guard interval DFT-Spread OFDM", time-domain implementation single-carrier method (for example, SC (Single Carrier)-QAM), etc.

The transceiver receives transmit data x701 and a control signal x700 as input, performs signal processing for transmission based on the control signal x700, and outputs transmit signals (x802_1 to x802_m). Furthermore, the transceiver receives receive signals (x802_1 to x802_m) and a control signal x700 as input, performs signal processing for reception based on the control signal x700, and outputs receive data x704.

Therefore, the transceiver panel antenna i of x705_i can perform transmit beamforming (transmit directionality control) and receive beamforming (receive directionality control).

[0255] In addition, regarding the specific actions of transmit beamforming (transmit directivity control) and receive beamforming (receive directivity control), as described above, the device performs transmit beamforming (transmit directivity control) and sends reference signals, feedback signals, frames, time slots, modulated signals, data codewords, etc.

[0256] In addition, Figure 9 In the figure, a structure is shown in which the antenna is shared by the transmitting panel antenna and the receiving panel antenna, but the transmitting panel antenna and the receiving panel antenna can also be separated. In addition, the number of transmitting panel antennas and the number of receiving panel antennas can be set separately.

[0257] Figure 10 This is another example of the structure of NR devices (communication devices) such as gNB, NR-UE, TRP, and terminals. Figure 10 In the Figure 9 The same reference numerals are assigned to parts that perform the same operations, and description thereof will be omitted.

[0258] When gNB has Figure 10 When the structure is used, one or more antennas from "transmitting and receiving antenna 1 of x805_1 to transmitting and receiving antenna m of x805_m" are used to perform transmitting beamforming (transmitting directivity control) and receiving beamforming (receiving directivity control).

[0259] And, have Figure 10 The gNB with a structure performs transmit beamforming (transmit directionality control) and sends, for example, a reference signal.

[0260] For example, Figure 10 The gNB with the structure uses the first transmission beam to send the first reference signal, uses the second transmission beam to send the second reference signal, and so on.

[0261] Furthermore, the gNB determines the "transmit beamforming and receive beamforming" used to communicate with each terminal, and transmits and receives feedback signals, frames, time slots, modulated signals, data symbols, etc.

[0262] When NR-UE has Figure 10 When the structure is used, one or more antennas from "transmitting and receiving antenna 1 of x805_1 to transmitting and receiving antenna m of x805_m" are used to perform transmitting beamforming (transmitting directivity control) and receiving beamforming (receiving directivity control).

[0263] And, have Figure 10 The NR-UE with the structure performs transmit beamforming (transmit directionality control) and sends a reference signal.

[0264] For example, Figure 10The NR-UE with the structure uses the first transmission beam to send the first reference signal, uses the second transmission beam to send the second reference signal, and so on.

[0265] Next, the "transmit beamforming and receive beamforming" used for communication with the gNB are determined, and feedback signals, frames, time slots, modulated signals, data codewords, etc. are sent and received.

[0266] In addition, Figure 10 In the figure, a structure is shown in which the antenna is shared by the transmitting panel antenna and the receiving panel antenna, but the transmitting panel antenna and the receiving panel antenna can also be separated. In addition, the number of transmitting panel antennas and the number of receiving panel antennas can be set separately.

[0267] In addition, the structure of "gNB, NR-UE and other communication devices" is not limited to Figure 1A 、 Figure 1B 、 Figure 1C 、 Figure 9 、 Figure 10 , these are just examples.

[0268] Figure 9 The transceiver panel antennas (x705_1 to x705_M) in the embodiment may be composed of a single antenna or multiple antennas. Furthermore, the transceiver panel antennas (x705_1 to x705_M) may be composed of a single antenna element or multiple antenna elements. The transceiver panel antennas (x705_1 to x705_M) are not limited to the configuration described in this embodiment.

Furthermore, the transceiver antennas (x805_1 to x805_m) may be composed of a single antenna element or multiple antenna elements. The transceiver antennas (x805_1 to x805_M) are not limited to the configuration described in this embodiment.

[0270] in addition, Figure 9 For example, the transceiver panel antenna i of x705_i in Figure 3 The structure of the transmitting panel antenna and Figure 4 In the case of a shared receiving panel antenna, Figure 3 The transmitting antenna 306_1 and Figure 4 The receiving antenna 401_1 is shared, so that the antenna is one, and the multiplication unit 304_1 and the multiplication unit 403_1 are connected to the shared antenna.

[0271] Likewise, Figure 3 The transmitting antenna 306_2 and Figure 4The receiving antenna 401_2 is shared, so that the antenna is one, and the multiplication unit 304_2 and the multiplication unit 403_2 are connected to the shared antenna.

Figure 3 The transmitting antenna 306_4 and Figure 4 The receiving antenna 401_4 is shared, so that the antenna is one, and the multiplication unit 304_4 and the multiplication unit 403_4 are connected to the shared antenna.

[0272] in addition, Figure 1A 、 Figure 1B 、 Figure 1C 、 Figure 9 、 Figure 10 The NR devices such as gNB, NR-UE, TRP, etc. with the structure can be wireless (communication) devices using low frequencies (for example, below 24 GHz) or wireless (communication) devices using high frequencies (for example, above 24 GHz).

[0273] For example, in the case of a wireless communication device using high frequencies, a transmitting antenna and a receiving antenna are sometimes referred to as omni-directional antennas.

[0274] About omnidirectional antennas:

[0275] gNB and NR-UE have Figure 9 In the case of a structure, one or more transceiver panel antennas from "transceiver panel antenna 1 of x705_1 to transceiver panel antenna M of x705_M" are used to receive signals.

[0276] In each of the transceiver panel antennas "from the transceiver panel antenna 1 of x705_1 to the transceiver panel antenna M of x705_M", the antennas constituting the transceiver panel antennas have been set to a certain reception beamforming (reception directivity control).

[0277] Furthermore, not all antennas constituting the transmitting and receiving panel antenna need be used for signal reception, and the settings of the reception beamforming (reception directivity control) may or may not be fixed in time.

[0278] In addition, the method of using the transceiver panel antenna during omnidirectional reception is not limited to the above example.

[0279] gNB and NR-UE have Figure 10 In the case of a structure, one or more transceiver antennas from "transceiver antenna 1 of x805_1 to transceiver antenna m of x805_m" are used to receive signals.

[0280] In each of the transceiver antennas "from the transceiver antenna 1 of x805_1 to the transceiver antenna m of x805_m", a certain reception beamforming (reception directivity control) setting has been performed on the antennas constituting the transceiver antennas.

[0281] Furthermore, not all antennas constituting the transmitting and receiving antennas need to be used for signal reception.

[0282] In addition, the method of using the transmitting and receiving antennas during omnidirectional reception is not limited to the above-mentioned example.

[0283] For example, in the case of a wireless communication device using high frequencies, a transmitting antenna and a receiving antenna are sometimes referred to as directional antennas.

[0284] About directional antennas:

[0285] gNB and NR-UE have Figure 9 In the case of a structure, one of the transceiver panel antennas from "transceiver panel antenna 1 of x705_1 to transceiver panel antenna M of x705_M" is used to receive signals.

[0286] It is assumed that, when performing signal detection based on directional reception, four types of reception beamforming (reception directivity control) are performed in each transmitting panel antenna, for example.

[0287] For example, when gNB, NR-UE, and TRP perform signal detection based on directional reception, reception beamforming (reception directivity control) using the first parameter, reception beamforming (reception directivity control) using the second parameter, reception beamforming (reception directivity control) using the third parameter, and reception beamforming (reception directivity control) using the fourth parameter are performed in the transceiver panel antenna 1 of x705_1.

[0288] In addition, when the gNB and NR-UE perform signal detection based on directional reception, reception beamforming (reception directivity control) using the 5th parameter, reception beamforming (reception directivity control) using the 6th parameter, reception beamforming (reception directivity control) using the 7th parameter, and reception beamforming (reception directivity control) using the 8th parameter are performed in the transceiver panel antenna 2 of x705_2.

[0289] Therefore, when performing signal detection based on directional reception, at the transceiver panel antenna i of x705_i, receive beamforming (receive directivity control) using the (4×i-3)th parameter, receive beamforming (receive directivity control) using the (4×i-2)th parameter, receive beamforming (receive directivity control) using the (4×i-1)th parameter, and receive beamforming (receive directivity control) using the (4×i)th parameter are performed. Note that i is an integer greater than or equal to 1 and less than or equal to M.

[0290] The gNB and NR-UE then perform receive beamforming (receive directionality control) using parameter 1 to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna 1 of x705_1.

[0291] The gNB and NR-UE perform receive beamforming (receive directivity control) using the second parameter to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna 1 of x705_1.

[0292] The gNB and NR-UE perform receive beamforming (receive directivity control) using the third parameter to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna 1 of x705_1.

[0293] The gNB and NR-UE perform receive beamforming (receive directivity control) using the fourth parameter to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna 1 of x705_1.

[0294] The gNB and NR-UE perform receive beamforming (receive directivity control) using parameter 5 to confirm the presence of a signal. Therefore, the gNB and NR-UE use the x705_2 transmit / receive panel antenna 2.

[0295] The gNB and NR-UE perform receive beamforming (receive directivity control) using parameter 6 to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna 2 of x705_2.

[0296] The gNB and NR-UE perform receive beamforming (receive directivity control) using parameter 7 to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna 2 of x705_2.

[0297] The gNB and NR-UE perform receive beamforming (receive directivity control) using parameter 8 to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna 2 of x705_2.

[0298] The gNB and NR-UE then perform receive beamforming (receive directivity control) using the (4×i-3)th parameter to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna i of x705_i.

[0299] The gNB and NR-UE perform receive beamforming (receive directivity control) using the (4×i-2)th parameter to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna i of x705_i.

[0300] The gNB and NR-UE perform receive beamforming (receive directivity control) using the (4×i-1)th parameter to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna i of x705_i.

[0301] The gNB and NR-UE perform receive beamforming (receive directivity control) using the (4×i)th parameter to confirm the presence of a signal. Therefore, the gNB and NR-UE use the transmit / receive panel antenna i of x705_i.

[0302] In addition, i is an integer greater than or equal to 1 and less than or equal to M.

[0303] Other examples are explained. gNB and NR-UE, TRP have Figure 10 In the case of a structure, one or more antennas from "transmitting and receiving antenna 1 of x805_1 to transmitting and receiving antenna m of x805_m" are used to perform receiving beamforming (receiving directivity control) to receive signals.

[0304] When performing signal detection based on directional reception, g types of receive beamforming (receive directivity control) are performed using one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m." Note that g is an integer greater than or equal to 2.

[0305] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the first parameter to confirm whether there is a signal.

[0306] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the second parameter to confirm whether there is a signal.

[0307] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the third parameter to confirm whether there is a signal.

[0308] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the fourth parameter to confirm whether there is a signal.

[0309] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the fifth parameter to confirm whether there is a signal.

[0310] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the sixth parameter to confirm whether there is a signal.

[0311] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the 7th parameter to confirm whether there is a signal.

[0312] The gNB and NR-UE use one or more antennas from "transmit / receive antenna 1 of x805_1 to transmit / receive antenna m of x805_m" to perform receive beamforming (receive directivity control) using the 8th parameter to confirm whether there is a signal.

[0313] Therefore, the gNB and NR-UE use one or more antennas from "x805_1's transmit / receive antenna 1 to x805_m's transmit / receive antenna m" to perform receive beamforming (receive directivity control) using the i-th parameter to confirm the presence of a signal. Here, i is an integer greater than or equal to 1 and less than or equal to g.

[0314] The methods of transmitting and receiving beamforming are not limited to the above examples. Figure 10 In the example, one or more of the transmit / receive antennas 1 of x805_1 to the transmit / receive antenna m of x805_m may be used to implement transmit beamforming. Figure 10 In the embodiment, one or more transceiver antennas from the transceiver antenna 1 of x805_1 to the transceiver antenna m of x805_m may be used to implement receive beamforming.

[0315] Next, use Figure 11An example of a wireless system related to the present invention will be described.

[0316] Set as, Figure 11 As shown, for example, there are TRP1 (transmission / reception point, Tx (Transmission) / Rx (Reception) point) of 1101_1, TRP2 of 1101_2, and NR-UE1 of 1100_1.

[0317] At this time, it is assumed that TRP1 of 1101_1 generates a transmission beam 1121_1 and uses the transmission beam 1121_1 to transmit a modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0318] Therefore, NR-UE1 of 1100_1 generates receiving beam 1130_1 and uses receiving beam 1130_1 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0319] In addition, it is assumed that NR-UE1 of 1100_1 generates a transmission beam 1120_1 and uses the transmission beam 1120_1 to transmit a modulated signal (UL: Uplink) of TRP2 addressed to 1101_2.

[0320] Therefore, TRP2 of 1101_2 generates receiving beam 1131_2 and uses receiving beam 1131_2 to receive the modulated signal sent by NR-UE1 of 1100_1 to TRP2.

[0321] Figure 12A Shown Figure 11 This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2 and NR-UE1 of 1100_1" on the frequency axis. Figure 12A The horizontal axis is frequency.

[0322] The TRP1 of 1101_1 uses the first frequency (frequency band) 1201 to transmit the modulated signal for downlink. At this time, the modulated signal transmitted by the TRP1 of 1101_1 is received by the NR-UE1 of 1100_1. Alternatively, Figure 12A As shown, TRP1 of 1101_1 performs communication using TDD (Time Division Duplex) and FDD (Frequency Division Duplex) at a frequency (band) other than the first frequency (band) 1201. Figure 12ADifferently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201 , TRP1 of 1101_1 does not perform communication.

[0323] The TRP2 of 1101_2 uses the first frequency (band) 1201 for receiving the modulated signal for uplink. At this time, the TRP2 of 1101_2 receives the modulated signal of the first frequency (band) 1201 transmitted by the NR-UE1 of 1100_1. Alternatively, it may be as follows: Figure 12A As shown, TRP2 of 1101_2 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 12A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, TRP2 of 1101_2 does not communicate.

[0324] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal transmitted by NR-UE1 of 1100_1 is received by TRP2 of 1101_2, for example. At this time, TRP1 of 1101_1 receives the modulation signal transmitted by NR-UE1 of 1100_1 on the first frequency (frequency band) 1201. In addition, it can be, for example Figure 12A As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 12A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0325] exist Figure 12A , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD will be described later.

[0326] Figure 12B Shown in Figure 11 、 Figure 12A An example of the transmission status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of . Figure 12B , the horizontal axis is time.

[0327] like Figure 12BAs shown, TRP1 of 1101_1 transmits frame 1251 to NR-UE1 of 1100_1 at the first time. In addition, NR-UE1 of 1100_1 transmits frame 1261 to TRP2 of 1101_2 at the first time.

[0328] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 11 As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0329] Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F Shown in Figure 11 、 Figure 12A The sending status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of Figure 12B Different examples. In addition, Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F , the horizontal axis is time.

[0330] like Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As shown, TRP1 of 1101_1 sends frame 1251 to NR-UE1 of 1100_1 at a certain time interval of the first time. In addition, NR-UE1 of 1100_1 sends frame 1261 to TRP2 of 1101_2 at a certain time interval of the first time.

[0331] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 11 As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0332] In addition, examples of the time configuration of the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 are not limited to Figure 12B 、 Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As long as the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 exist at the same time, any time configuration is possible.

[0333] Figure 13A This is a diagram showing an example of the configuration of the TRP1 of 1101_1. The communication device 1302 receives data 1301 as input and outputs a modulated signal (group) 1303 and a control signal 1304 containing a signal to be sent to the NR-UE1 of 1100_1. Then, the transmitting antenna (group) 1305 receives the modulated signal (group) 1303 and the control signal 1304 as input, generates a transmission signal based on the control signal 1304, and outputs the transmission signal as an electric wave. In this case, for example, Figure 11 As shown, the transmit signal is transmitted using transmit beam 1121_1.

[0334] The communication device 1302 takes data 1351 as input and outputs data for Figure 12A Modulated signal (group) 1352 and control signal 1353 for communication using "TDD or FDD" are received by transmitting and receiving antenna (group) 1354. Then, the transmitting and receiving antenna (group) 1354 receives the modulated signal (group) 1352 and control signal 1353 for communication using "TDD or FDD" as input, generates a transmission signal for communication using "TDD or FDD" based on the control signal 1353, and outputs the transmission signal as a radio wave.

[0335] Transceiver antenna (group) 1354 receiving and Figure 12A The communication device 1302 receives the received signal 1371, performs demodulation, error correction code decoding, and other processing on the received signal 1371, and outputs received data 1372.

[0336] Thus, for example, TRP1 of 1101_1 may have the following structure, which is used as follows: Figure 11 、 Figure 12A As shown, the modulated signal is sent to the NR-UE1 of 1100_1, and communication using "TDD or FDD" is implemented. In addition, the TRP1 of 1101_1 can also be Figure 13A The TRP 1 of 1101_1 does not include a configuration related to communication using "TDD or FDD." In this case, the TRP 1 of 1101_1 is composed of, for example, a communication device 1302 and a transmission antenna (group) 1305.

[0337] Furthermore, when TRP1 of 1101_1 communicates using TDD or FDD, the target of the TDD or FDD communication can be NR-UE1 of 1100_1 or another NR-UE. This improves data transmission efficiency for TRP1 of 1101_1. Furthermore, when the target of the TDD or FDD communication is NR-UE1 of 1100_1, data transmission efficiency for NR-UE1 of 1100_1 can be improved.

[0338] exist Figure 13A In the , although they are called "transmitting antenna (group)" and "transmitting and receiving antenna (group)", they can also be called antenna ports or other names. Figure 13A Among them, the characteristic point is that TRP1 of 1101_1 has independent "antenna ports for transmitting modulated signals (group) 1303 including signals sent to NR-UE1 of 1100_1" and "antenna ports for communication using 'TDD or FDD'".

[0339] In addition, an antenna port can also be a logical antenna (antenna group) composed of one or more physical antennas. That is, an antenna port does not necessarily refer to a physical antenna, but sometimes refers to an array antenna composed of multiple antennas. For example, sometimes it is not specified how many physical antennas an antenna port consists of, but it is specified as the minimum unit that a terminal station can send a reference signal (reference signal). In addition, an antenna port is sometimes also specified as a unit or minimum unit by which a weight of a precoding vector or a precoding matrix is ​​multiplied.

[0340] Regarding the "transmitting antenna (group)" and "transmitting and receiving antenna (group)", although only one is shown in the drawings, there may be multiple "transmitting antenna (group)" and "transmitting and receiving antenna (group)" can be composed of one antenna or multiple antennas.

[0341] In addition, you can also Figure 13A In, with Figure 13A The specific operations of the "transmitting antenna group", "receiving antenna group" and "transmitting and receiving antenna group" other than those shown will be described later.

[0342] Figure 13B 1101_2 is a diagram showing a configuration example of a device of TRP2. Figure 13A The same reference numerals are attached to the parts with the same operation, and some descriptions are omitted. Figure 11The modulated signal (received signal 1313) is transmitted by NR-UE1 of 1100_1 shown in FIG. Furthermore, receiving antenna (group) 1316 receives control signal 1314 as input and operates as a receiving antenna based on control signal 1314. Communication device 1302 then receives received signal 1313 as input, performs processing such as demodulation and error correction code decoding, and outputs received data 1315.

[0343] The communication device 1302 takes data 1351 as input and outputs data for Figure 12A Modulated signal (group) 1352 and control signal 1353 for communication using "TDD or FDD" are received by transmitting and receiving antenna (group) 1354. Then, the transmitting and receiving antenna (group) 1354 receives the modulated signal (group) 1352 and control signal 1353 for communication using "TDD or FDD" as input, generates a transmission signal for communication using "TDD or FDD" based on the control signal 1353, and outputs the transmission signal as a radio wave.

[0344] Transceiver antenna (group) 1354 receiving and Figure 12A The communication device 1302 receives the received signal 1371, performs demodulation, error correction code decoding, and other processing on the received signal 1371, and outputs received data 1372.

[0345] Thus, for example, TRP2 of 1101_2 may have the following structure, which is used as follows: Figure 11 、 Figure 12A As shown in FIG1 , the modulated signal sent by NR-UE1 of 1100_1 is received and communication using "TDD or FDD" is performed. In addition, TRP2 of 1101_2 can also be Figure 13B In this case, TRP2 of 1101_2 is composed of, for example, a communication device 1302 and a receiving antenna (group) 1316.

[0346] Furthermore, when TRP2 of 1101_2 communicates using "TDD or FDD," the target of the communication using "TDD or FDD" can be NR-UE1 of 1100_1 or another NR-UE. This improves data transmission efficiency for TRP2 of 1101_2. Furthermore, when the target of the communication using "TDD or FDD" is NR-UE1 of 1100_1, data transmission efficiency for NR-UE1 of 1100_1 can be improved.

[0347] exist Figure 13BIn the , although they are called "receiving antenna (group)" and "transmitting and receiving antenna (group)", they can also be called antenna ports or other names. Figure 13B Among them, the characteristic point is that TRP2 of 1101_2 has independent "antenna ports for receiving modulated signals transmitted by NR-UE1 of 1100_1" and "antenna ports for communication using 'TDD or FDD'".

[0348] Regarding the "receiving antenna (group)" and "transmitting and receiving antenna (group)", although only one is shown in the drawings, there may be multiple "receiving antenna (group)" and "transmitting and receiving antenna (group)" can be composed of one antenna or multiple antennas.

[0349] In addition, you can also Figure 13B In, with Figure 13B The specific operations of the "transmitting antenna group", "receiving antenna group" and "transmitting and receiving antenna group" other than those shown will be described later.

[0350] Figure 14 The configuration example of the NR-UE1 device of 1100_1 is shown. The communication device 1402 takes the data 1401 as input and outputs a modulation signal (group) 1403 and a control signal 1404 including a signal sent to the TRP2 of 1101_2. Then, the transmitting antenna (group) 1405 takes the modulation signal (group) 1403 and the control signal 1404 as input, generates a transmission signal based on the control signal 1494, and outputs the transmission signal as an electric wave. At this time, for example, Figure 11 As shown, the transmit signal is transmitted using transmit beam 1120_1.

[0351] The receiving antenna (group) 1416 receives the Figure 11 The modulated signal (received signal 1413) is transmitted by TRP1 of 1101_1 shown in FIG. Furthermore, receiving antenna (group) 1416 receives control signal 1414 as input and operates as a receiving antenna based on control signal 1414. Communication device 1402 then receives received signal 1413 as input, performs processing such as demodulation and error correction code decoding, and outputs received data 1415.

[0352] In addition, the communication device 1402 takes data 1451 as input and outputs data for Figure 12AModulated signal (group) 1452 and control signal 1453 for communication using "TDD or FDD" are received in the transmitting and receiving antenna (group) 1454. Then, the transmitting and receiving antenna (group) 1454 receives the modulated signal (group) 1452 and control signal 1453 for communication using "TDD or FDD" as input, generates a transmission signal for communication using "TDD or FDD" based on the control signal 1453, and outputs the transmission signal as a radio wave.

[0353] Transceiver antenna (group) 1454 receiving and Figure 12A Received signal 1471 related to communication using "TDD or FDD" in the communication apparatus 1402 is then inputted, performs processing such as demodulation and error correction code decoding, and outputs received data 1472.

[0354] Thus, for example, NR-UE1 of 1100_1 may have the following structure, which is used as follows: Figure 11 、 Figure 12A As shown in FIG1 , the NR-UE1 of 1101_1 receives the modulated signal sent by the TRP1 of 1101_1 and implements communication using "TDD or FDD". Figure 14 The NR-UE 1 of 1100_1 does not include a structure related to communication using "TDD or FDD". In this case, the NR-UE 1 of 1100_1 is composed of, for example, a communication device 1402, a transmitting antenna (group) 1405, and a receiving antenna (group) 1416.

[0355] In addition, Figure 11 In the example, an example is shown in which TRP1 of 1101_1 transmits a modulated signal for downlink, but it is also possible that TRP2 of 1101_2 transmits a modulated signal for downlink, and NR-UE1 of 1100_1 has the function of receiving "the modulated signal for downlink transmitted by TRP2 of 1101_2" and transmitting a modulated signal for uplink to TRP2 of 1101_2. In this case, it is assumed that the frequency (band) of the signal transmitted by NR-UE1 of 1100_1 is the same as or partially the same as the frequency (band) of the signal received by NR-UE1 of 1100_1. In addition, it is assumed that the signal transmitted by NR-UE1 of 1100_1 and the signal received by NR-UE1 of 1100_1 exist at the same time, or partially exist at the same time.

[0356] exist Figure 14 In FIG, although the transmitting antenna group 1405, the receiving antenna group 1416, and the transmitting and receiving antenna group 1454 are independent structures, they are not limited to this. Figure 14In the embodiment, the "transmitting antenna group 1405" and the "transmitting antenna function of the transceiver antenna group 1454" may be shared (for example, implemented by a single transmitting antenna group). In addition, the "receiving antenna group 1416" and the "receiving antenna function of the transceiver antenna group 1454" may be shared (for example, implemented by a single receiving antenna group).

[0357] Furthermore, when NR-UE1 of 1100_1 communicates using "TDD or FDD," the communication target using "TDD or FDD" may be TRP1 of 1101_1 and / or TRP2 of 1101_2, or another TRP. As a result, NR-UE1 of 1100_1 can achieve improved data transmission efficiency.

[0358] exist Figure 14 In the , although they are called "transmitting antenna (group)", "receiving antenna (group)", "transmitting and receiving antenna (group)", they can also be called antenna ports or other names. Figure 14 In the example, the NR-UE1 of 1100_1 has an independent "antenna port for transmitting a modulated signal (group) 1403 including a signal sent to TRP2 of 1101_2" and an "antenna port for communication using 'TDD or FDD'". Figure 14 Among them, the NR-UE1 of 1100_1 has independent "antenna ports for sending modulated signals (group) 1403 including signals sent to TRP2 of 1101_2", "antenna ports for receiving modulated signals sent by TRP1 of 1101_1", and "antenna ports for communication using 'TDD or FDD'", which are characteristic points.

[0359] Regarding the "transmitting antenna (group)", "receiving antenna (group)", and "transceiver antenna (group)", although only one is shown in the accompanying drawings, there may be multiple "transmitting antenna (group)", "receiving antenna (group)", and "transceiver antenna (group)" can be composed of one antenna or multiple antennas.

[0360] Next, use Figure 15 To Figure 11 Examples of different wireless systems are described.

[0361] Set as, Figure 15 As shown, for example, there are TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, and NR-UE3 of 1100_3. Figure 15 In the Figure 11The same reference numerals are assigned to parts that perform the same operations, and description thereof will be omitted.

[0362] Set as, in Figure 15 In the example, TRP1 of 1101_1 generates a transmit beam 1121_1 and uses the transmit beam 1121_1 to transmit a modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0363] Therefore, NR-UE1 of 1100_1 generates receiving beam 1130_1 and uses receiving beam 1130_1 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0364] In addition, it is assumed that NR-UE1 of 1100_1 generates a transmission beam 1120_1 and uses the transmission beam 1120_1 to transmit a modulated signal (UL: Uplink) of TRP2 addressed to 1101_2.

[0365] Therefore, TRP2 of 1101_2 generates receiving beam 1131_2 and uses receiving beam 1131_2 to receive the modulated signal sent by NR-UE1 of 1100_1 to TRP2.

[0366] Assume that NR-UE2 of 1100_2 generates a transmission beam 1120_2 and uses the transmission beam 1120_2 to transmit a modulated signal (UL: Uplink) of TRP1 to 1101_1.

[0367] Therefore, TRP1 of 1100_1 generates receiving beam 1131_1 and uses receiving beam 1131_1 to receive the modulated signal sent by NR-UE2 of 1101_2 to TRP1.

[0368] Assume that TRP2 of 1101_2 generates transmission beam 1121_2 and uses transmission beam 1121_2 to transmit a modulated signal (DL: Downlink) to NR-UE3 of 1100_3.

[0369] Therefore, NR-UE3 of 1100_3 generates receiving beam 1130_3 and uses receiving beam 1130_3 to receive the modulated signal sent by TRP2 of 1101_2 to NR-UE3.

[0370] In addition, NR-UE2 of 1100_2 generates receiving beam 1130_2 and uses receiving beam 1130_2 to receive the modulated signal sent by TRP to NR-UE3.

[0371] Assume that NR-UE3 of 1100_3 generates transmit beam 1120_3 and uses transmit beam 1120_3 to send the modulated signal to TRP.

[0372] Figure 16A Shown Figure 15 This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, and NR-UE3 of 1100_3" on the frequency axis. Figure 16A 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0373] The TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit a modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by the NR-UE1 of 1100_1, for example. Figure 16A As shown, TRP1 of 1101_1 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201 .

[0374] The TRP1 of 1101_1 receives the modulated signal for uplink using the second frequency (frequency band) 1202. At this time, the TRP1 of 1101_1 receives the modulated signal of the second frequency (frequency band) transmitted by the NR-UE2 of 1100_2.

[0375] It can also be, with Figure 16A Differently, TRP1 of 1101_1 does not perform communication at frequencies (frequency bands) other than "first frequency (frequency band) 1201 and second frequency (frequency band) 1202".

[0376] The TRP2 of 1101_2 uses the first frequency (band) 1201 for receiving the modulated signal for uplink. At this time, the TRP2 of 1101_2 receives the modulated signal of the first frequency (band) 1201 transmitted by the NR-UE1 of 1100_1. Figure 16A As shown, TRP2 of 1101_2 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201.

[0377] TRP2 of 1101_2 transmits a modulated signal for downlink using the second frequency (band) 1202. At this time, the modulated signal of the second frequency (band) 1202 transmitted by TRP2 of 1101_2 is received by NR-UE3 of 1100_3, for example.

[0378] It can also be, with Figure 16A Differently, TRP2 of 1101_2 does not communicate at frequencies (frequency bands) other than "first frequency (frequency band) 1201, second frequency (frequency band) 1202".

[0379] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by TRP2 of 1101_2, for example. At this time, TRP1 of 1101_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1. In addition, it can be, for example Figure 16A As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 16A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0380] NR-UE2 of 1100_2 uses the second frequency (band) 1202 for receiving modulation signals for downlink and for sending modulation signals for uplink. At this time, the modulation signal of the second frequency (band) 1202 sent by NR-UE2 of 1100_2 is received by TRP1 of 1101_1, for example. At this time, NR-UE2 of 1100_2 receives the modulation signal of the second frequency (band) 1202 sent by TRP. (This TRP is in Figure 16A (not shown) In addition, it can be, for example Figure 16A As shown, the NR-UE2 of 1100_2 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the second frequency (frequency band) 1202. Figure 16A Differently, at frequencies (frequency bands) other than the second frequency (frequency band) 1202, NR-UE2 of 1100_2 does not communicate.

[0381] NR-UE3 of 1100_3 uses the second frequency (band) 1202 for receiving the modulated signal for downlink and for sending the modulated signal for uplink. At this time, the modulated signal of the second frequency (band) 1202 sent by NR-UE3 of 1100_3 is received by TRP. (Regarding this TRP, Figure 16A (not shown) and the NR-UE3 of 1100_3 receives the modulated signal of the second frequency (band) 1202 sent by the TRP2 of 1101_2. Figure 16AAs shown, the NR-UE3 of 1100_3 performs communication using TDD and communication using FDD at a frequency (band) other than the second frequency (band) 1202. Figure 16A Differently, at frequencies (frequency bands) other than the second frequency (frequency band) 1202, NR-UE3 of 1100_3 does not communicate.

[0382] exist Figure 16A , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD will be described later.

[0383] Figure 12B Shown in Figure 15 、 Figure 16A An example of the transmission status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of . Figure 12B , the horizontal axis is time.

[0384] like Figure 12B As shown, TRP1 of 1101_1 transmits frame 1251 to NR-UE1 of 1100_1 at the first time. In addition, NR-UE1 of 1100_1 transmits frame 1261 to TRP2 of 1101_2 at the first time.

[0385] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0386] Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F Shown in Figure 15 、 Figure 16A The sending status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of Figure 12B Different examples. In addition, Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F , the horizontal axis is time.

[0387] like Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As shown, TRP1 of 1101_1 sends frame 1251 to NR-UE1 of 1100_1 at a certain time interval of the first time. In addition, NR-UE1 of 1100_1 sends frame 1261 to TRP2 of 1101_2 at a certain time interval of the first time.

[0388] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0389] In addition, examples of the time configuration of the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 are not limited to Figure 12B 、 Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As long as the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 exist at the same time, any time configuration is possible.

[0390] Figure 16B Shown in Figure 15 、 Figure 16A In the case of TRP( Figure 15 (not shown) and an example of the transmission status of NR-UE2 of 1100_2 on the time axis. In addition, Figure 16B , the horizontal axis is time.

[0391] like Figure 16B As shown, the TRP sends a frame 1252 to the NR-UE2 of 1100_2 at the second time. In addition, the NR-UE2 of 1100_2 sends a frame 1262 to the TRP1 of 1101_1 at the second time.

[0392] Therefore, the NR-UE2 of 1100_2 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15As described, there is a high possibility that the transmitting direction (from NR-UE2 toward TRP1) of NR-UE2 of 1100_2 is different from the receiving direction (from TRP toward NR-UE2). Therefore, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality of the received signal can be improved.

[0393] Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F Shown in Figure 15 、 Figure 16A The status of TRP and NR-UE2 of 1100_2 sent on the time axis under the condition of Figure 16B Different examples. In addition, Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F , the horizontal axis is time.

[0394] like Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F As shown, the TRP sends a frame 1252 to the NR-UE2 of 1100_2 at a certain time interval of the second time. In addition, the NR-UE2 of 1100_2 sends a frame 1262 to the TRP1 of 1101_1 at a certain time interval of the second time.

[0395] Therefore, the NR-UE2 of 1100_2 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE2 toward TRP1) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP toward NR-UE2). Therefore, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality of the received signal can be improved.

[0396] In addition, examples of the time configuration of frames sent by TRP and frames sent by NR-UE2 of 1100_2 are not limited to Figure 16B 、 Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F As long as the frames sent by TRP and the frames sent by NR-UE2 of 1100_2 exist at the same time, the configuration can be any time.

[0398] like Figure 16G As shown, TRP2 of 1101_2 sends frame 1253 to NR-UE3 of 1100_3 at the third time. In addition, NR-UE3 of 1100_3 sends frame 1253 to TRP( Figure 15 Frame 1263 (not shown).

[0399] Therefore, the NR-UE3 of 1100_3 transmits and receives at the same frequency (or part of the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE3 toward TRP) of NR-UE3 of 1100_3 is different from the receiving direction (from TRP2 of 1101_2 toward NR-UE3). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0400] Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K Shown in Figure 15 、 Figure 16A The sending status of TRP2 of 1101_2 and NR-UE3 of 1100_3 on the time axis is the same as Figure 16G Different examples. In addition, Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K , the horizontal axis is time.

[0401] like Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K As shown, TRP2 of 1101_2 sends frame 1253 to NR-UE3 of 1100_3 in a certain time interval of the third time. In addition, NR-UE3 of 1100_3 sends frame 1263 to TRP in a certain time interval of the third time.

[0402] Therefore, the NR-UE3 of 1100_3 transmits and receives at the same frequency (or part of the same frequency) at the same time. Figure 15As described, there is a high possibility that the transmitting direction (from NR-UE3 toward TRP) of NR-UE3 of 1100_3 is different from the receiving direction (from TRP2 of 1101_2 toward NR-UE3). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0403] In addition, examples of the time configuration of the frame sent by TRP2 of 1101_2 and the frame sent by NR-UE3 of 1100_3 are not limited to Figure 16G 、 Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K As long as the frames sent by TRP2 of 1101_2 and the frames sent by NR-UE3 of 1100_3 exist at the same time, the configuration can be arbitrary in time.

[0404] Figure 17 Shown Figure 15 The communication status of "TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, and NR-UE3 of 1100_3" on the frequency axis is the same as Figure 16A Different examples. In addition, Figure 17 In the process, the same as Figure 12, Figure 16A The same reference numerals are assigned to parts that operate in the same manner, and the horizontal axis represents frequency.

[0405] The TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit a modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by the NR-UE1 of 1100_1, for example. Figure 17 As shown, TRP1 of 1101_1 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201 .

[0406] The TRP1 of 1101_1 receives the modulated signal for uplink using the second frequency (frequency band) 1202. At this time, the TRP1 of 1101_1 receives the modulated signal of the second frequency (frequency band) transmitted by the NR-UE2 of 1100_2.

[0407] Alternatively, it can be Figure 17 Differently, TRP1 of 1101_1 does not perform communication at frequencies (frequency bands) other than "first frequency (frequency band) 1201 and second frequency (frequency band) 1202".

Figure 17 As shown, TRP2 of 1101_2 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201.

[0409] TRP2 of 1101_2 transmits a modulated signal for downlink using the third frequency (band) 1203. At this time, the modulated signal of the third frequency (band) 1203 transmitted by TRP2 of 1101_2 is received by NR-UE3 of 1100_3, for example.

[0410] Alternatively, it can be Figure 17 Differently, TRP2 of 1101_2 does not communicate at frequencies (frequency bands) other than "the first frequency (frequency band) 1201 and the third frequency (frequency band) 1203".

[0411] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by TRP2 of 1101_2, for example. At this time, TRP1 of 1101_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1. In addition, it can be, for example Figure 17 As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 17 Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0412] NR-UE2 of 1100_2 uses the second frequency (band) 1202 for receiving modulation signals for downlink and for sending modulation signals for uplink. At this time, the modulation signal of the second frequency (band) 1202 sent by NR-UE2 of 1100_2 is received by TRP1 of 1101_1, for example. At this time, NR-UE2 of 1100_2 receives the modulation signal of the second frequency (band) 1202 sent by TRP. (This TRP is in Figure 17 (not shown) In addition, it can be, for example Figure 17As shown, the NR-UE2 of 1100_2 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the second frequency (frequency band) 1202.

Figure 17 As shown, the NR-UE3 of 1100_3 performs communication using TDD and communication using FDD at a frequency (band) other than the third frequency (band) 1203. Figure 17 Differently, at frequencies (frequency bands) other than the third frequency (frequency band) 1203, NR-UE3 of 1100_3 does not communicate.

[0414] exist Figure 17 , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD will be described later.

[0415] Figure 12B Shown in Figure 15 、 Figure 17 An example of the transmission status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of . Figure 12B , the horizontal axis is time.

[0416] like Figure 12B As shown, TRP1 of 1101_1 transmits frame 1251 to NR-UE1 of 1100_1 at the first time. In addition, NR-UE1 of 1100_1 transmits frame 1261 to TRP2 of 1101_2 at the first time.

[0417] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0418] Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F Shown in Figure 15 、 Figure 17 The sending status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of Figure 12B Different examples. In addition, Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F , the horizontal axis is time.

[0419] like Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As shown, TRP1 of 1101_1 sends frame 1251 to NR-UE1 of 1100_1 at a certain time interval of the first time. In addition, NR-UE1 of 1100_1 sends frame 1261 to TRP2 of 1101_2 at a certain time interval of the first time.

[0420] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0421] In addition, examples of the time configuration of the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 are not limited to Figure 12B 、 Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As long as the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 exist at the same time, any time configuration is possible.

[0422] Figure 16B Shown in Figure 15 、 Figure 17 In the case of TRP( Figure 15 (not shown) and an example of the transmission status of NR-UE2 of 1100_2 on the time axis. In addition, Figure 16B , the horizontal axis is time.

[0423] like Figure 16B As shown, the TRP sends a frame 1252 to the NR-UE2 of 1100_2 at the second time. In addition, the NR-UE2 of 1100_2 sends a frame 1262 to the TRP1 of 1101_1 at the second time.

[0424] Therefore, the NR-UE2 of 1100_2 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE2 toward TRP1) of NR-UE2 of 1100_2 is different from the receiving direction (from TRP toward NR-UE2). Therefore, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality of the received signal can be improved.

[0425] Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F Shown in Figure 15 、 Figure 17 The status of TRP and NR-UE2 of 1100_2 sent on the time axis under the condition of Figure 16B Different examples. In addition, Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F , the horizontal axis is time.

[0426] like Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F As shown, the TRP sends a frame 1252 to the NR-UE2 of 1100_2 at a certain time interval of the second time. In addition, the NR-UE2 of 1100_2 sends a frame 1262 to the TRP1 of 1101_1 at a certain time interval of the second time.

[0427] Therefore, the NR-UE2 of 1100_2 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15As described, there is a high possibility that the transmitting direction (from NR-UE2 toward TRP1) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP toward NR-UE2). Therefore, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality of the received signal can be improved.

[0428] In addition, examples of the time configuration of frames sent by TRP and frames sent by NR-UE2 of 1100_2 are not limited to Figure 16B 、 Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F As long as the frames sent by TRP and the frames sent by NR-UE2 of 1100_2 exist at the same time, the configuration can be any time.

[0429] Figure 16G Shown in Figure 15 、 Figure 17 This figure shows an example of the transmission status of TRP2 of 1101_2 and NR-UE3 of 1100_3 on the time axis under the condition of . Figure 16G , the horizontal axis is time.

[0430] like Figure 16G As shown, TRP2 of 1101_2 sends frame 1253 to NR-UE3 of 1100_3 at the third time. In addition, NR-UE3 of 1100_3 sends frame 1253 to TRP( Figure 15 Frame 1263 (not shown).

[0431] Therefore, the NR-UE3 of 1100_3 transmits and receives at the same frequency (or part of the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE3 toward TRP) of NR-UE3 of 1100_3 is different from the receiving direction (from TRP2 of 1101_2 toward NR-UE3). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0432] Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K Shown in Figure 15 、 Figure 17 The sending status of TRP2 of 1101_2 and NR-UE3 of 1100_3 on the time axis is the same as Figure 16G Different examples. In addition, Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K , the horizontal axis is time.

[0433] like Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K As shown, TRP2 of 1101_2 sends frame 1253 to NR-UE3 of 1100_3 in a certain time interval of the third time. In addition, NR-UE3 of 1100_3 sends frame 1263 to TRP in a certain time interval of the third time.

[0434] Therefore, the NR-UE3 of 1100_3 transmits and receives at the same frequency (or part of the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE3 toward TRP) of NR-UE3 of 1100_3 is different from the receiving direction (from TRP2 of 1101_2 toward NR-UE3). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0435] In addition, examples of the time configuration of the frame sent by TRP2 of 1101_2 and the frame sent by NR-UE3 of 1100_3 are not limited to Figure 16G 、 Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K As long as the frames sent by TRP2 of 1101_2 and the frames sent by NR-UE3 of 1100_3 exist at the same time, the configuration can be arbitrary in time.

[0436] Figure 18 Shown Figure 15 The communication status of "TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, and NR-UE3 of 1100_3" on the frequency axis is the same as Figure 16A 、 Figure 17 Different examples. In addition, Figure 18 In the process, the same as Figure 12, Figure 16A 、 Figure 17 The same reference numerals are assigned to parts that operate in the same manner, and the horizontal axis represents frequency.

[0437] The TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit a modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by the NR-UE1 of 1100_1, for example. Figure 18 As shown, TRP1 of 1101_1 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201 .

[0438] The TRP1 of 1101_1 receives the modulated signal for uplink using the first frequency (band) 1201. At this time, the TRP1 of 1101_1 receives the modulated signal of the first frequency (band) 1201 transmitted by the NR-UE2 of 1100_2.

[0439] Alternatively, it can be Figure 18 Differently, at frequencies (frequency bands) other than the "first frequency (frequency band) 1201", TRP1 of 1101_1 does not perform communication.

[0440] The TRP2 of 1101_2 uses the first frequency (band) 1201 for receiving the modulated signal for uplink. At this time, the TRP2 of 1101_2 receives the modulated signal of the first frequency (band) 1201 transmitted by the NR-UE1 of 1100_1. Figure 18 As shown, TRP2 of 1101_2 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201.

[0441] TRP2 of 1101_2 transmits a modulated signal for downlink using the first frequency (band) 1201. At this time, the modulated signal of the first frequency (band) 1201 transmitted by TRP2 of 1101_2 is received by NR-UE3 of 1100_3, for example.

[0442] Alternatively, it can be Figure 18 Differently, at frequencies (frequency bands) other than the "first frequency (frequency band) 1201", TRP2 of 1101_2 does not communicate.

[0443] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by TRP2 of 1101_2, for example. In addition, TRP1 of 1101_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1. In addition, it can be, for example, Figure 18As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 18 Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0444] NR-UE2 of 1100_2 uses the first frequency (frequency band) 1201 for receiving the modulation signal for downlink and for sending the modulation signal for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 sent by NR-UE2 of 1100_2 is received by TRP1 of 1101_1, for example. And, NR-UE2 of 1100_2 receives the modulation signal of the first frequency (frequency band) 1201 sent by TRP. (This TRP is in Figure 18 (not shown) In addition, it can be, for example Figure 18 As shown, the NR-UE2 of 1100_2 performs communication using TDD and communication using FDD at a frequency (band) other than the first frequency (band) 1201. Figure 18 Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE2 of 1100_2 does not communicate.

[0445] NR-UE3 of 1100_3 uses the first frequency (band) 1201 for receiving the modulation signal for downlink and for transmitting the modulation signal for uplink. At this time, the modulation signal of the first frequency (band) 1201 transmitted by NR-UE3 of 1100_3 is received by TRP. (Regarding this TRP, Figure 18 (not shown) and the NR-UE3 of 1100_3 receives the modulated signal of the first frequency (band) 1201 sent by the TRP2 of 1101_2. In addition, it can be, for example Figure 18 As shown, the NR-UE3 of 1100_3 performs communication using TDD and communication using FDD at a frequency (band) other than the first frequency (band) 1201. Figure 18 Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE3 of 1100_3 does not communicate.

[0446] exist Figure 18 , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD will be described later.

[0448] like Figure 12B As shown, TRP1 of 1101_1 transmits frame 1251 to NR-UE1 of 1100_1 at the first time. In addition, NR-UE1 of 1100_1 transmits frame 1261 to TRP2 of 1101_2 at the first time.

[0449] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0450] Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F Shown in Figure 15 、 Figure 18 The sending status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of Figure 12B Different examples. In addition, Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F , the horizontal axis is time.

[0451] like Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As shown, TRP1 of 1101_1 sends frame 1251 to NR-UE1 of 1100_1 at a certain time interval of the first time. In addition, NR-UE1 of 1100_1 sends frame 1261 to TRP2 of 1101_2 at a certain time interval of the first time.

[0452] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15As described, there is a high possibility that the transmitting direction (from NR-UE1 toward TRP2) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP1 toward NR-UE1). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0453] In addition, examples of the time configuration of the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 are not limited to Figure 12B 、 Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As long as the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 exist at the same time, any time configuration is possible.

[0455] like Figure 16B As shown, the TRP sends a frame 1252 to the NR-UE2 of 1100_2 at the second time. In addition, the NR-UE2 of 1100_2 sends a frame 1262 to the TRP1 of 1101_1 at the second time.

[0456] Therefore, the NR-UE2 of 1100_2 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE2 toward TRP1) of NR-UE2 of 1100_2 is different from the receiving direction (from TRP toward NR-UE2). Therefore, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality of the received signal can be improved.

[0457] Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F Shown in Figure 15 、 Figure 18 The status of TRP and NR-UE2 of 1100_2 sent on the time axis under the condition of Figure 16B Different examples. In addition, Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F , the horizontal axis is time.

[0458] like Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F As shown, the TRP sends a frame 1252 to the NR-UE2 of 1100_2 at a certain time interval of the second time. In addition, the NR-UE2 of 1100_2 sends a frame 1262 to the TRP1 of 1101_1 at a certain time interval of the second time.

[0459] Therefore, the NR-UE2 of 1100_2 transmits and receives at the same frequency (or partially the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE2 toward TRP1) of NR-UE1 of 1100_1 is different from the receiving direction (from TRP toward NR-UE2). Therefore, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality of the received signal can be improved.

[0460] In addition, examples of the time configuration of frames sent by TRP and frames sent by NR-UE2 of 1100_2 are not limited to Figure 16B 、 Figure 16C 、 Figure 16D 、 Figure 16E 、 Figure 16F As long as the frames sent by TRP and the frames sent by NR-UE2 of 1100_2 exist at the same time, the configuration can be any time.

[0462] like Figure 16G As shown, TRP2 of 1101_2 sends frame 1253 to NR-UE3 of 1100_3 at the third time. In addition, NR-UE3 of 1100_3 sends frame 1253 to TRP( Figure 15 Frame 1263 (not shown).

[0463] Therefore, the NR-UE3 of 1100_3 transmits and receives at the same frequency (or part of the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE3 toward TRP) of NR-UE3 of 1100_3 is different from the receiving direction (from TRP2 of 1101_2 toward NR-UE3). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

In addition, Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K , the horizontal axis is time.

[0465] like Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16K As shown, TRP2 of 1101_2 sends frame 1253 to NR-UE3 of 1100_3 in a certain time interval of the third time. In addition, NR-UE3 of 1100_3 sends frame 1263 to TRP in a certain time interval of the third time.

[0466] Therefore, the NR-UE3 of 1100_3 transmits and receives at the same frequency (or part of the same frequency) at the same time. Figure 15 As described, there is a high possibility that the transmitting direction (from NR-UE3 toward TRP) of NR-UE3 of 1100_3 is different from the receiving direction (from TRP2 of 1101_2 toward NR-UE3). As a result, the possibility of separating the transmitting beam and the receiving beam can be increased, self-interference can be reduced, and the data quality in the received signal can be improved.

[0467] In addition, examples of the time configuration of the frame sent by TRP2 of 1101_2 and the frame sent by NR-UE3 of 1100_3 are not limited to Figure 16G 、 Figure 16H 、 Figure 16I 、 Figure 16J 、 Figure 16KAs long as the frames sent by TRP2 of 1101_2 and the frames sent by NR-UE3 of 1100_3 exist at the same time, the configuration can be arbitrary in time.

[0468] exist Figure 18 In the case of Figure 15 The TRP1 of 1101_1 can simultaneously or partially simultaneously perform "reception of the modulated signal sent by NR-UE2 of 1100_2" and "sending of the modulated signal sent to NR-UE1 of 1100_1".

[0469] in addition, Figure 15 The TRP2 of 1101_2 can simultaneously or partially simultaneously perform "reception of the modulated signal sent by NR-UE3 of 1100_3" and "sending of the modulated signal sent to NR-UE1 of 1100_1".

[0470] For Figure 15 middle Figure 16A Implementation of Figure 15 middle Figure 17 Implementation of Figure 15 middle Figure 18 An example of the structure of "NR-UE1 of 1100_1, NR-UE2 of 1100_2, and NR-UE3 of 1100_3" is as follows: Figure 14 In addition, about Figure 14 Since the explanation has been given, the explanation is omitted.

[0471] For Figure 15 middle Figure 16A Implementation of Figure 15 middle Figure 17 Implementation of Figure 15 middle Figure 18 An example of the structure of "TRP1 of 1101_1, TRP2 of 1101_2" is as follows: Figure 19 .exist Figure 19 In the Figure 13A 、 Figure 13B The same reference numerals are given to parts that perform the same operations, and their description has been omitted because they have already been described.

[0472] For example, in Figure 15 The TRP1 of 1101_1 is Figure 19 In the configuration of , TRP1 of 1101_1 transmits the modulated signal destined for NR-UE1 of 1100_1 from transmit antenna group 1305. Furthermore, TRP1 of 1101_1 receives the modulated signal transmitted by NR-UE2 of 1100_2 using receive antenna group 1316.

[0473] In addition, Figure 15The TRP2 of 1101_2 is Figure 19 In the configuration of , TRP2 of 1101_2 transmits the modulated signal destined for NR-UE3 of 1100_3 from transmit antenna group 1305. Furthermore, TRP2 of 1101_2 receives the modulated signal transmitted by NR-UE1 of 1100_1 using receive antenna group 1316.

[0474] exist Figure 19 In FIG, although the transmitting antenna group 1305, the receiving antenna group 1316, and the transmitting and receiving antenna group 1354 are independent structures, they are not limited to this. Figure 19 In the embodiment, the "transmitting antenna group 1305" and the "transmitting antenna function of the transceiver antenna group 1354" may be shared (for example, implemented by a single transmitting antenna group). In addition, the "receiving antenna group 1316" and the "receiving antenna function of the transceiver antenna group 1354" may be shared (for example, implemented by a single receiving antenna group).

[0475] Set as, in Figure 15 , the TRP1 of 1101_1 sends a modulated signal to the first NR-UE and receives the modulated signal sent by the first NR-UE. At this time, it is assumed that the "frequency (band) of the modulated signal sent by the TRP1 of 1101_1 to the first NR-UE" is the same as or partially the same as the "frequency (band) of the modulated signal sent by the first NR-UE to the TRP1 of 1101_1". In addition, it is assumed that the modulated signal sent by the TRP1 of 1101_1 to the first NR-UE and the modulated signal sent by the first NR-UE to the TRP1 of 1101_1 exist at the same time, or partially exist at the same time. It can be that the TRP1 of 1101_1 supports such a communication method.

[0476] Let, similarly, Figure 15 , TRP2 of 1101_2 sends a modulated signal to the second NR-UE and receives the modulated signal sent by the second NR-UE. At this time, it is assumed that "the frequency (band) of the modulated signal sent by TRP2 of 1101_2 to the second NR-UE" is the same as or partially the same as "the frequency (band) of the modulated signal sent by the second NR-UE to TRP2 of 1101_2". In addition, it is assumed that the modulated signal sent by TRP2 of 1101_2 to the second NR-UE and the modulated signal sent by TRP2 of 1101_2 to the second NR-UE exist at the same time, or partially exist at the same time. It can be that TRP2 of 1101_2 supports such a communication method.

[0477] An example of the modulated signals sent by the TRP and NR-UE mentioned above is described.

[0483] Let, “TRP X” be Figure 15 The 1101_1 TRP1, "TRP Y" is " Figure 15 The 1101_2 TRP2", "NR-UE Z" is " Figure 15 NR-UE1 of 1100_1".

[0484] Example 3:

[0485] Let, “TRP X” be Figure 15 TRP not shown (which has been described) "TRP Y" is " Figure 15 The 1101_1 TRP1", "NR-UE Z" is " Figure 15 1100_2 NR-UE2".

[0486] Example 4:

[0487] Let, “TRP X” be Figure 15 The TRP2 of 1101_1" is "TRP Y" Figure 15 TRP not shown (which has been explained)", "NR-UE Z" is " Figure 15 1100_3 NR-UE3".

[0488] like Figure 20A As shown, "NR-UE Z" sends control code element 2041 at the first time. Assume that control code element 2041 includes control information for establishing communication with TRP, etc.

[0489] Here, as an example, the control code element 2041 may include "whether NR-UE Z' is capable of implementing Figure 11 、 Figure 15 At this time, "TRP X" and "TRP Y" can know whether "NR-UE Z" can communicate by obtaining control code element 2041. Figure 11 、 Figure 15 That kind of communication.

[0490] In addition, the control code element 2041 may include the "Request to Implement" Figure 11 、 Figure 15 At this time, "TRP X" and "TRP Y" can know that "NR-UE Z" requests to carry out communication by obtaining control code element 2041. Figure 11 、 15 Such a communication situation.

[0491] And, "TRP X" sends a control symbol 2001 at the second time. The control symbol 2001 may include, for example, "regarding the communication with 'NR-UE Z'". Figure 11 、 Figure 15 "NR-UE Z" can obtain "information related to TRP (or gNB) for obtaining the modulated signal sent to 'NR-UE Z'" and "information related to the communication method of the modulated signal sent to 'NR-UE Z'" by obtaining control code element 2001.

[0492] In addition, the control code element 2001 may include "whether it can be implemented Figure 11 、 Figure 15 Such communication" such as "TRPX" capability (capabilities) information.

[0493] "TRP Y" sends a control symbol 2021 at the third time. The control symbol 2021 may include, for example, "regarding the communication with 'NR-UE Z'". Figure 11 、 Figure 15"NR-UE Z" can obtain "information related to the TRP (or gNB) that is the destination of the modulated signal to be sent" and "information related to the communication method of the modulated signal to be sent by 'NR-UE Z' to 'TRP Y'" (for example, the number of modulated signals (the number of levels), information on the modulation method, information on the error correction code (information on the coding rate and code length)) by obtaining the control code element 2021.

[0494] In addition, the control code element 2021 may include "whether it can be implemented Figure 11 、 Figure 15 Such communication" such "TRPY" capability (capabilities) information.

[0495] Furthermore, TRP X transmits reference symbol 2002 at the fourth time, and NR-UE Z transmits reference symbol 2042 at the fourth time. Thus, at the fourth time, NR-UE Z receives reference symbol 2002 and reference symbol 2042. NR-UE Z thereby estimates the state of the modulation signal transmitted by TRP X and the state of the modulation signal transmitted by NR-UE Z, and obtains state information of the modulation signal transmitted by TRP X and the state information of the modulation signal transmitted by NR-UE Z.

[0496] In addition, the existence of the reference symbol 2002 transmitted by "NR-UE Z" and the reference symbol 2042 transmitted by "NR-UE Z" is not limited to Figure 20A For example, reference symbol 2002 and reference symbol 2042 may be arranged to exist on the time axis in a manner that does not overlap in time. That is, reference symbol 2042 may not exist during a time period when reference symbol 2002 exists, and reference symbol 2002 may not exist during a time period when reference symbol 2042 exists (TDM: Time Division Multiplexing).

[0497] Furthermore, TRP X transmits data symbol 2003 at the fifth time, and NR-UE Z transmits data symbol 2043 at the fifth time. At this point, NR-UE Z may receive a modulated signal including data symbol 2003 and data symbol 2043. However, since it has estimated the states of each modulated signal based on reference symbols 2002 and 2042, it is able to demodulate data symbol 2003. Furthermore, TRP Y receives and demodulates the modulated signal including data symbol 2043.

[0498] By adopting the above method, it is possible to achieve a more appropriate implementation Figure 11 、 Figure 15 That's the effect of communication.

[0499] Figure 20B The transmission of signals of each device "TRP X", "TRP Y", and "NR-UE Z" on the time axis is shown. Figure 20A Different examples, Figure 20B In the example, the horizontal axis is time. Figure 20B In the Figure 20A The same reference numerals are assigned to parts that perform the same operations, and description thereof will be omitted.

[0500] Figure 20B Zhongyu Figure 20A The difference is that the control codeword 2021 is not sent by "TRP Y". Figure 20B In the example, "TRP X" uses control symbol 2001 to send control symbol 2021, such as "regarding communication with 'NR-UE Z'". Figure 11 、 Figure 15 "Request information (or specified information) related to the communication method of the modulated signal sent by 'NR-UE Z' to 'TRP Y' (for example, the number of modulated signals (the number of levels), information on the modulation method, information on the error correction code (information on the coding rate and code length)).

[0501] Therefore, by obtaining control code element 2001, "NR-UE Z" can obtain "information related to the TRP (or gNB) that is the destination of the modulated signal to be sent" and "information related to the communication method of the modulated signal to be sent."

[0502] In addition, the control code element 2001 may include "whether it can be implemented Figure 11 、 Figure 15 Such communication" such "TRPY" capability (capabilities) information.

[0503] By adopting the above method, it is possible to achieve a more appropriate implementation Figure 11 、 Figure 15 That's the effect of communication.

[0504] Figure 20C The transmission of signals of each device "TRP X", "TRP Y", and "NR-UE Z" on the time axis is shown. Figure 20A 、 Figure 20B Different examples, Figure 20CIn the example, the horizontal axis is time. Figure 20C In the Figure 20A The same reference numerals are assigned to parts that perform the same operations, and description thereof will be omitted.

[0505] Figure 20C Zhongyu Figure 20A The difference is that the control codeword 2001 is not sent by "TRP X". Figure 20C In the example, "TRP Y" uses control symbol 2021 to send information contained in control symbol 2001, such as "regarding communication with 'NR-UE Z'". Figure 11 、 Figure 15 Information about the TRP of such communication (for example, information about the gNB and cell information)", "Information related to the communication method of the modulated signal sent by the TRP to 'NR-UEZ' (for example, the number of modulated signals (the number of levels), information about the modulation method, information about the error correction code (information about the coding rate and code length))".

[0506] Therefore, by obtaining control code element 2021, "NR-UE Z" can obtain "information related to TRP (or gNB) for obtaining the modulated signal sent to 'NR-UE Z'" and "information related to the communication method of the modulated signal sent to 'NR-UE Z'".

[0507] In addition, the control code element 2021 may include "whether it can be implemented Figure 11 、 Figure 15 Such communication" such as "TRPX" capability (capabilities) information.

[0508] By adopting the above method, it is possible to achieve a more appropriate implementation Figure 11 、 Figure 15 That's the effect of communication.

[0509] The control symbol 2001, reference symbol 2002, data symbol 2003, and control symbol 2021 may belong to one of PCH (paging channel), BCH (broadcast channel), DL-SCH (downlink shared channel), BCCH (broadcast control channel), PCCH (paging control channel), CCCH (common control channel), common search space, PBCH (physical broadcast channel), SS (synchronization signals), PDCCH (physical downlink control channel), PDSCH (physical downlink shared channel), etc. However, the present invention is not limited to these.

[0510] The control symbol 2041, the reference symbol, and the data symbol 2043 may also belong to one of the UL-SCH (uplink shared channel), the PUCCH (physical uplink control channel), the PUSCH (physical uplink shared channel), the PRACH (physical random access channel), etc. However, this is not limiting.

[0511] Next, use Figure 21 To Figure 11 、 Figure 15 Different wireless system examples are given to illustrate. Figure 21 As shown, there are TRP1 of 1101_1, TRP2 of 1101_2, and NR-UE1 of 1100_1. Figure 21 In the Figure 11 The same reference numerals are assigned to parts that perform the same operations, and part of the description is omitted.

[0512] Set as, Figure 21In the example, TRP1 of 1101_1 generates a transmit beam 1121_1 and uses the transmit beam 1121_1 to transmit a modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0513] Therefore, NR-UE1 of 1100_1 generates receiving beam 1130_1 and uses receiving beam 1130_1 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0514] In addition, it is assumed that NR-UE1 of 1100_1 generates a transmission beam 1120_1 and uses the transmission beam 1120_1 to transmit a modulated signal (UL: Uplink) addressed to TRP1 of 1101_1.

[0515] Therefore, TRP1 of 1101_1 generates receiving beam 1131_1 and uses receiving beam 1131_1 to receive the modulated signal sent by NR-UE1 of 1100_1 to TRP1.

[0516] In addition, it is assumed that NR-UE1 of 1100_1 and TRP2 of 1101_2 communicate using "TDD or FDD" (2101).

[0517] Figure 22 Shown Figure 21 This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2 and NR-UE1 of 1100_1" on the frequency axis. Figure 22 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0518] The TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit a modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by the NR-UE1 of 1100_1, for example. Figure 22 As shown, TRP1 of 1101_1 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201 .

[0519] The NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving the modulation signal for the downlink and for transmitting the modulation signal for the uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by the NR-UE1 of 1100_1 is received by the TRP1 of 1101_1, for example. In addition, the NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by the TRP1 of 1101_1. In addition, it can be, for example, Figure 22 As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 22 Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0520] Furthermore, TRP2 of 1101_2 and NR-UE1 of 1100_1 perform communication using TDD or FDD at the second frequency (frequency band) 1202. Figure 22 As shown, TRP2 of 1101_2 does not communicate at frequencies (frequency bands) other than the second frequency (frequency band) 1202. In addition, TRP2 of 1101_2 can also communicate using TDD or FDD at frequencies (frequency bands) other than the second frequency (frequency band) 1202.

[0521] exist Figure 22 , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD will be described later.

[0522] Figure 12B Shown in Figure 21 、 Figure 22 An example of the transmission status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of . Figure 12B , the horizontal axis is time.

[0523] like Figure 12B As shown, TRP1 of 1101_1 transmits frame 1251 to NR-UE1 of 1100_1 at the first time. In addition, NR-UE1 of 1100_1 transmits frame 1261 to TRP1 of 1101_1 at the first time.

[0524] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same time on the same frequency (or partially the same frequency). In this case, considering the transmission direction (from NR-UE1 to TRP1) and the reception direction (from TRP1 to NR-UE1) of NR-UE1 of 1100_1, NR-UE1 of 1100_1 preferably has a function for canceling self-interference. This also applies to TRP1 of 1101_1.

[0525] Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F Shown in Figure 21 、 Figure 22 The sending status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of Figure 12B Different examples. In addition, Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F , the horizontal axis is time.

[0526] like Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As shown, TRP1 of 1101_1 sends frame 1251 to NR-UE1 of 1100_1 at a certain time interval of the first time. In addition, NR-UE1 of 1100_1 sends frame 1261 to TRP1 of 1101_1 at a certain time interval of the first time.

[0527] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same time on the same frequency (or partially the same frequency). In this case, considering the transmission direction (from NR-UE1 to TRP1) and the reception direction (from TRP1 to NR-UE1) of NR-UE1 of 1100_1, NR-UE1 of 1100_1 preferably has a function for canceling self-interference. This also applies to TRP1 of 1101_1.

[0528] In addition, examples of the time configuration of the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 are not limited to Figure 12B 、 Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As long as the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 exist at the same time, any time configuration is possible.

[0529] In addition, if Figure 22 As shown, TRP2 of 1101_2 and NR-UE1 of 1100_1 perform communication using, for example, TDD or FDD at the second frequency (frequency band) 1202. This improves the transmission efficiency of data of NR-UE1 of 1100_1.

[0530] Figure 23A Shown Figure 21 An example of the communication status of "TRP1 of 1101_1 and NR-UE1 of 1100_1" on the frequency axis. Figure 23B Shown Figure 21 This is an example of the communication status of "TRP2 of 1101_1 and NR-UE1 of 1100_1" on the frequency axis. Figure 23A 、 Figure 23B 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0531] First, yes Figure 23A For explanation. Figure 23A As shown, the TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit the modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by the NR-UE1 of 1100_1, for example. Figure 23A As shown, TRP1 of 1101_1 can perform communication using TDD or communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201 .

[0532] The NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving the modulation signal for the downlink and for transmitting the modulation signal for the uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by the NR-UE1 of 1100_1 is received by the TRP1 of 1101_1, for example. In addition, the NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by the TRP1 of 1101_1. In addition, it can be, for example, Figure 23A As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 23A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0533] exist Figure 23A, the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD will be described later.

[0534] Figure 12B Shown in Figure 21 、 Figure 23A An example of the transmission status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of . Figure 12B , the horizontal axis is time.

[0535] like Figure 12B As shown, TRP1 of 1101_1 transmits frame 1251 to NR-UE1 of 1100_1 at the first time. In addition, NR-UE1 of 1100_1 transmits frame 1261 to TRP1 of 1101_1 at the first time.

[0536] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same time on the same frequency (or partially the same frequency). In this case, considering the transmission direction (from NR-UE1 to TRP1) and the reception direction (from TRP1 to NR-UE1) of NR-UE1 of 1100_1, NR-UE1 of 1100_1 preferably has a function for canceling self-interference. This also applies to TRP1 of 1101_1.

[0537] Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F Shown in Figure 21 、 Figure 23A The sending status of TRP1 of 1101_1 and NR-UE1 of 1100_1 on the time axis under the condition of Figure 12B Different examples. In addition, Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F , the horizontal axis is time.

[0538] like Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As shown, TRP1 of 1101_1 sends frame 1251 to NR-UE1 of 1100_1 at a certain time interval of the first time. In addition, NR-UE1 of 1100_1 sends frame 1261 to TRP1 of 1101_1 at a certain time interval of the first time.

[0539] Therefore, the NR-UE1 of 1100_1 transmits and receives at the same time on the same frequency (or partially the same frequency). In this case, considering the transmission direction (from NR-UE1 to TRP1) and the reception direction (from TRP1 to NR-UE1) of NR-UE1 of 1100_1, NR-UE1 of 1100_1 preferably has a function for canceling self-interference. This also applies to TRP1 of 1101_1.

[0540] In addition, examples of the time configuration of the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 are not limited to Figure 12B 、 Figure 12C 、 Figure 12D 、 Figure 12E 、 Figure 12F As long as the frames sent by TRP1 of 1101_1 and the frames sent by NR-UE1 of 1100_1 exist at the same time, any time configuration is possible.

[0541] Then, Figure 23B For explanation. Figure 23B As shown, TRP2 of 1101_2 uses the first frequency (band) 1201 to transmit a modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by TRP2 of 1101_2 is received by NR-UE1 of 1100_1, for example.

[0542] The NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by the NR-UE1 of 1100_1 is received by, for example, the TRP2 of 1101_2. Furthermore, the NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by the TRP2 of 1101_2. In addition, the communication between the TRP2 of 1101_2 and the NR-UE1 of 1100_1 using the first frequency (frequency band) 1201 is, for example, "communication using TDD or communication using FDD".

[0543] The TRP2 of 1101_2 can perform communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 23B TDD and FDD will be explained later.

[0544] Figure 23C Shown Figure 21An example of the communication status of NR-UE1 of 1100_1, TRP1 of 1101_1, and TRP2 of 1101_2 over time. Figure 23C In the example, the horizontal axis is time. In addition, Figure 23C yes Figure 23A 、 Figure 23B The communication status of the first frequency (frequency band) 1201.

[0545] like Figure 23C As shown, NR-UE1 of 1100_1 transmits a modulated signal in "TDD or FDD" at a certain time of the first time (2301_1). In addition, the transmission destination of the modulated signal is TRP2 of 1101_2.

[0546] In addition, if Figure 23C As shown, TRP2 of 1101_2 transmits a modulated signal in "TDD or FDD" at a certain time of the first time (2321_1). In addition, the transmission destination of the modulated signal includes NR-UE1 of 1100_1.

[0547] Similarly, NR-UE1 of 1100_1 transmits a modulated signal in "TDD or FDD" at a certain time of the third time (2301_2). In addition, the transmission destination of the modulated signal is TRP2 of 1101_2.

[0548] In addition, if Figure 23C As shown, TRP2 of 1101_2 transmits a modulated signal in "TDD or FDD" at a certain time of the third time (2321_1). In addition, the transmission destination of the modulated signal includes NR-UE1 of 1100_1.

[0549] In addition, about Figure 23C The first and third time communications have been used Figure 23B Explained.

[0550] like Figure 23C As shown, NR-UE1 of 1100_1 performs " Figure 23A The modulation signal of the first frequency (frequency band) 1201 communication is sent (2302_1). In addition, the destination of sending the modulation signal is TRP1 1101_1.

[0551] In addition, if Figure 23C As shown, TRP1 of 1101_1 performs " Figure 23A The modulation signal is sent (2312_1) in the communication of the first frequency (frequency band) 1201. In addition, the destination of sending the modulation signal includes NR-UE1 1100_1.

[0552] Likewise, if Figure 23C As shown, NR-UE1 of 1100_1 performs " Figure 23A The modulation signal of the first frequency (frequency band) 1201 communication is sent (2302_2). In addition, the sending destination of the modulation signal is TRP1 1101_1.

[0553] In addition, if Figure 23C As shown, TRP1 of 1101_1 performs " Figure 23A The modulation signal is sent (2312_2) in the communication of the first frequency (frequency band) 1201. In addition, the destination of sending the modulation signal includes NR-UE1 1100_1.

[0554] In addition, about Figure 23C The second and fourth time communications have been used Figure 23A Explained.

[0555] As mentioned above, when using Figure 23A Figure 23B The “ Figure 21 In the case where the NR-UE1 of 1100_1, the TRP1 of 1101_1, and the TRP2 of 1101_2 communicate at the first frequency (band) 1201, as shown in FIG. Figure 23C As described above, the NR-UE1 of 1100_1 implements the following communications in a time-switched manner in the first frequency (frequency band) 1201: "communication using TDD", "communication using FDD", "communication using Figure 23A In this way, the frequency utilization efficiency in the communication system can be improved, and the NR-UE selects an appropriate communication method according to the situation, thereby achieving an effect of achieving both improved communication speed and improved reception quality.

[0556] in addition," Figure 21 The NR-UE1 of 1100_1, TRP1 of 1101_1, and TRP2 of 1101_2 perform "communication using TDD", "communication using FDD", and "communication using TDD" in time in the first frequency (frequency band) 1201. Figure 23A The method of communication of the first frequency (frequency band) 1201 is not limited to Figure 23C For example, no matter how "communication using TDD", "communication using FDD", " Figure 23A The same effect can be achieved by implementing the communication using the first frequency (frequency band) 1201.

[0557] "Communication using TDD" and "communication using FDD" are explained.

[0558] Figure 24 This is an example of NR-UE communicating with TRP using TDD, where the horizontal axis represents time.

[0559] like Figure 24 As shown, the TRP sends the "first frame of the modulation signal of the downlink using frequency (band) A" 2411_1 at the first time. At this time, the NR-UE does not send the modulation signal at the first time.

[0560] The NR-UE transmits the "first frame of the uplink modulation signal using frequency (band) A" 2401_1 at the second time. At this time, the TRP does not transmit the modulation signal at the second time.

[0561] The TRP transmits the "second frame of the modulation signal of the downlink using frequency (band) A" 2411_2 at the third time. At this time, the NR-UE does not transmit the modulation signal at the third time.

[0562] The NR-UE transmits the "second frame of the uplink modulation signal using frequency (band) A" 2401_2 at the fourth time. At this time, the TRP does not transmit the modulation signal at the fourth time.

[0563] Figure 25A This is the first example of NR-UE communicating with TRP using FDD, where the horizontal axis represents time.

[0564] like Figure 25A As shown, the TRP sends the "first frame of the modulation signal of the downlink using frequency (band) B" 2511_1 at the first time. At this time, the NR-UE does not send the modulation signal at the first time.

[0565] The NR-UE transmits "the first frame of the uplink modulation signal using frequency (band) A" 2501_1 at the second time. At this time, the TRP does not transmit the modulation signal at the second time. In addition, frequency (band) A and frequency (band) B are different frequencies (bands).

[0566] The TRP transmits the "second frame of the modulation signal of the downlink using frequency (band) B" 2511_2 at the third time. At this time, the NR-UE does not transmit the modulation signal at the third time.

[0567] The NR-UE transmits the "second frame of the uplink modulation signal using frequency (band) A" 2501_2 at the fourth time. At this time, the TRP does not transmit the modulation signal at the fourth time.

[0568] Figure 25BThis is the second example when NR-UE communicates with TRP using FDD, where the horizontal axis is time.

[0569] like Figure 25B As shown, the TRP transmits the "first frame of the downlink modulation signal using frequency (band) B" 2511_1 at the first time. Furthermore, the NR-UE transmits the "first frame of the uplink modulation signal using frequency (band) A" 2501_1 at the first time. In addition, frequency (band) A and frequency (band) B are different frequencies (bands).

[0570] Figure 25C This is the third example when NR-UE communicates with TRP using FDD, where the horizontal axis is time.

[0571] like Figure 25C As shown, the TRP transmits the "first frame of the downlink modulation signal using frequency (band) B" 2511_1 at the first time. Furthermore, the NR-UE transmits the "first frame of the uplink modulation signal using frequency (band) A" 2501_1 in a portion of the first time. Note that frequency (band) A and frequency (band) B are different frequencies (bands).

[0572] Figure 25D This is the fourth example when NR-UE communicates with TRP using FDD, where the horizontal axis is time.

[0573] like Figure 25D As shown, the TRP transmits "the first frame of the downlink modulation signal using frequency (band) B" 2511_1 in a portion of the first time. Furthermore, the NR-UE transmits "the first frame of the uplink modulation signal using frequency (band) A" 2501_1 in the first time. Note that frequency (band) A and frequency (band) B are different frequencies (bands).

[0574] In this embodiment, the TRP is described, but if the TRP is implemented as any one of "a base station, a repeater, an access point, a broadcast station, a gNB (g Node B), an eNB (e Node B), a node, a server, a satellite, an operable device (equipment that operates based on electricity, such as "electric vehicles, electric motorcycles (e-scooters), electric bicycles, movable robots, electric skateboards, electric assisted bicycles, electric assisted skateboards", cars, motorcycles, bicycles, ships, aircraft, airplanes, etc.), a terminal, a mobile phone, a smartphone, a tablet computer, a notebook computer, a computer, a personal computer, a home appliance (home electrical machinery), an apparatus in a factory, a communication device / playback device such as an IoT (Internet of Things) device", it can also be implemented in the same manner. Therefore, the TRP of this embodiment can also be referred to as "a base station, a repeater, an access point, a broadcast station, a gNB, an eNB, a node, a server, a satellite, an operable device such as the above-mentioned example, a terminal, a mobile phone, a smartphone, a tablet computer, a notebook computer, a computer, a personal computer, a home appliance, an apparatus in a factory, a communication device / playback device such as an IoT device, etc." This point also applies in this specification.

[0575] In addition, although the present embodiment describes the NR-UE, the same implementation is possible if the NR-UE is implemented as any one of "TRP, base station, repeater, access point, broadcast station, gNB, eNB, node, server, satellite, any of the above-mentioned operable devices, terminals, mobile phones, smartphones, tablet computers, laptop computers, personal computers, home appliances, in-factory devices, communication devices / playback devices, etc." Therefore, the NR-UE of the present embodiment may also be referred to as "TRP, base station, repeater, access point, broadcast station, gNB, eNB, node, server, satellite, any of the above-mentioned operable devices, terminals, mobile phones, smartphones, tablet computers, laptop computers, personal computers, home appliances, in-factory devices, communication devices / playback devices, etc." This applies equally throughout this specification.

[0576] In this embodiment, as the structure of the TRP, NR-UE and other devices, Figure 1A 、 Figure 1B 、 Figure 1C 、 Figure 9 、 Figure 10 While the above descriptions have been provided, the device configuration is not limited to these examples. While examples have been provided of devices equipped with configurations for performing transmit beamforming and receive beamforming, this embodiment can be implemented even with devices that do not have configurations for performing transmit beamforming and receive beamforming. This applies equally throughout this specification.

[0577] Sometimes, a device can achieve the effect of eliminating self-interference by performing transmit beamforming or receive beamforming. Alternatively, self-interference elimination can be achieved by having a self-interference elimination function without performing beamforming.

[0578] In addition, for example, when a device such as a TRP or NR-UE transmits a modulated signal, one or more transmitting antennas or two or more transmitting antennas may be used to transmit one or more modulated signals. This also applies to the present specification.

[0579] exist Figure 11 、 Figure 15 、 Figure 21 The number of TRPs in the wireless system is set to 2, but it is not limited to this, and the number of TRPs can be set to more than 1 or more than 2 for implementation.

[0580] In addition, Figure 15 The number of NR-UEs in the wireless system is set to 3, but is not limited to this, and the implementation can be carried out by setting the number of NR-UEs to more than 1 or more than 2.

[0581] This embodiment describes the case where multiple TRPs exist in a wireless system. In this case, multiple TRPs can communicate with each other, share information, and control each other. Furthermore, the system can also contain devices that control multiple TRPs. This applies equally to all aspects of this specification.

[0582] (Implementation Method 2)

[0583] In Implementation 2, a modified example of Implementation 1 is described. The configuration and basic operations of the gNB and NR-UE have already been described in Implementation 1, and therefore their description is omitted here.

[0584] Figure 26 An example of a wireless system in this embodiment is shown.

[0585] Set as, Figure 26 As shown, for example, there are TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE4 of 1100_4, and NR-UE5 of 1100_5. Figure 26 In the Figure 11 The same reference numerals are assigned to parts that perform the same operations, and part of the description is omitted.

[0586] Set as, Figure 26In the example, TRP1 of 1101_1 generates a transmit beam 1121_1 and uses the transmit beam 1121_1 to transmit a modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0587] Therefore, NR-UE1 of 1100_1 generates receiving beam 1130_1 and uses receiving beam 1130_1 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0588] In addition, let Figure 26 In the example, TRP1 of 1101_1 generates a transmit beam 1121_4 and uses the transmit beam 1121_4 to transmit a modulated signal (DL: Downlink) to NR-UE4 of 1100_4.

[0589] Therefore, NR-UE4 of 1100_4 generates a receiving beam 1130_4 and uses the receiving beam 1130_4 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE4.

[0590] Set as, Figure 26 In the example, TRP1 of 1101_1 generates a transmit beam 1121_5 and uses the transmit beam 1121_5 to transmit a modulated signal (DL: Downlink) to NR-UE5 of 1100_5.

[0591] Therefore, NR-UE5 of 1100_5 generates receiving beam 1130_5 and uses receiving beam 1130_5 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE5.

[0592] Assume that NR-UE1 of 1100_1 generates a transmission beam 1120_1 and uses the transmission beam 1120_1 to transmit a modulated signal (UL: Uplink) of TRP2 to 1101_2.

[0593] Therefore, TRP2 of 1101_2 generates receiving beam 1132_1 and uses receiving beam 1132_1 to receive the modulated signal sent by NR-UE1 of 1100_1 to TRP2.

[0594] Assume that NR-UE4 of 1100_4 generates a transmission beam 1120_4 and uses the transmission beam 1120_4 to transmit a modulated signal (UL: Uplink) of TRP2 to 1101_2.

[0595] Therefore, TRP2 of 1101_2 generates receiving beam 1132_4 and uses receiving beam 1132_4 to receive the modulated signal sent by NR-UE4 of 1100_4 to TRP2.

[0596] Assume that NR-UE5 of 1100_5 generates transmission beam 1120_5 and uses transmission beam 1120_5 to transmit the modulated signal (UL: Uplink) of TRP2 sent to 1101_2.

[0597] Therefore, TRP2 of 1101_2 generates receiving beam 1132_5 and uses receiving beam 1132_5 to receive the modulated signal sent by NR-UE5 of 1100_5 to TRP2.

[0598] Figure 27A Shown Figure 26 This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE4 of 1100_4, and NR-UE5 of 1100_5" on the frequency axis. Figure 27A 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0599] The TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit a modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by, for example, the NR-UE1 of 1100_1, the NR-UE4 of 1100_4, and the NR-UE5 of 1100_5. Alternatively, it may be, for example, Figure 27A As shown, TRP1 of 1101_1 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 27A Differently, at frequencies (frequency bands) other than the "first frequency (frequency band) 1201", TRP1 of 1101_1 does not perform communication.

[0600] The TRP2 of 1101_2 uses the first frequency (frequency band) 1201 for receiving the modulated signal for uplink. At this time, the TRP2 of 1101_2 receives the "modulated signal transmitted by NR-UE1 of 1100_1", "modulated signal transmitted by NR-UE4 of 1100_4", and "modulated signal transmitted by NR-UE5 of 1100_5" of the first frequency (frequency band) 1201. In addition, it can be, for example Figure 27AAs shown, TRP2 of 1101_2 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 27A Differently, at frequencies (frequency bands) other than the "first frequency (frequency band) 1201", TRP2 of 1101_2 does not communicate.

[0601] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by TRP2 of 1101_2, for example. In addition, NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by TRP1 of 1101_1. In addition, it can be, for example, Figure 27A As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 27A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0602] The NR-UE4 of 1100_4 uses the first frequency (band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (band) 1201 transmitted by the NR-UE4 of 1100_4 is received by the TRP2 of 1101_2, for example. In addition, the NR-UE4 of 1100_4 receives the modulation signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1. In addition, it can be, for example, Figure 27A As shown, the NR-UE4 of 1100_4 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 27A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE4 of 1100_4 does not communicate.

[0603] The NR-UE5 of 1100_5 uses the first frequency (band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (band) 1201 transmitted by the NR-UE5 of 1100_5 is received by, for example, the TRP2 of 1101_2. In addition, the NR-UE5 of 1100_5 receives the modulation signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1. In addition, it can be, for example, Figure 27AAs shown, the NR-UE5 of 1100_5 performs communication using TDD and communication using FDD at a frequency (band) other than the first frequency (band) 1201. Figure 27A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, the NR-UE5 of 1100_5 does not communicate.

[0604] exist Figure 27A An example is described in which the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but this embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" can also be partially the same frequency (frequency band).

[0605] Figure 27B Shown in Figure 26 、 Figure 27A An example of the existence interval on the time axis of the downlink modulation signal sent by the TRP "TRP1 of 1101_1, etc." and the uplink modulation signal sent by the NR-UE "NR-UE1 of 1100_1, NR-UE4 of 1100_4, NR-UE5 of 1100_5, etc.". In addition, Figure 27B , the horizontal axis is time.

[0606] like Figure 27B As shown, a downlink modulation signal exists in the first time, that is, a downlink modulation signal existence interval 2751 exists here. In addition, an uplink modulation signal exists in the first time, that is, an uplink modulation signal existence interval 2761 exists here.

[0607] Figure 27C 、 Figure 27D 、 Figure 27E 、 Figure 27F Shown in Figure 26 、 Figure 27A Under the condition of "1101_1's TRP1, etc.", the downlink modulation signal sent by TRP and the uplink modulation signal sent by NR-UE "1100_1's NR-UE1, 1100_4's NR-UE4, 1100_5's NR-UE5, etc." exist on the time axis. Figure 27B Different examples. In addition, Figure 27C 、 Figure 27D 、 Figure 27E 、 Figure 27F , the horizontal axis is time.

[0608] like Figure 27C 、 Figure 27D 、 Figure 27E 、 Figure 27FAs shown, a downlink modulation signal exists in a certain time interval of the first time, that is, a downlink modulation signal existence interval 2751 exists therein. In addition, an uplink modulation signal exists in a certain time interval of the first time, that is, an uplink modulation signal existence interval 2761 exists therein.

[0609] Therefore, the "downlink modulation signal" and the "uplink modulation signal" exist at the same frequency (or partially the same frequency) and at the same time.

[0610] In addition, examples of the temporal arrangement of “downlink modulation signals and uplink modulation signals” are not limited to Figure 27C 、 Figure 27D 、 Figure 27E 、 Figure 27F As long as the "downlink modulation signal and uplink modulation signal" both exist at the same time, any time configuration is possible.

[0611] In the first embodiment, for example, a case where the “modulation signal sent by the NR-UE1 of 1100_1” and the “modulation signal sent by the TRP and addressed to the NR-UE1 of 1100_1” exist at the same frequency (or partially the same frequency) is described. In the present embodiment, an example different from the first embodiment is described in which the “modulation signal sent by the NR-UE1 of 1100_1” and the “modulation signal sent by the TRP and addressed to the NR-UE1 of 1100_1” exist at the same frequency (or partially the same frequency).

[0612] Figure 28 Shown Figure 27B 、 Figure 27C 、 Figure 27D 、 Figure 27E 、 Figure 27F An example of the structure of the "downlink modulation signal existence interval 2751" and the "uplink modulation signal existence interval 2761" on the time axis. Figure 28 In , the horizontal axis is time. In addition, let, Figure 27B 、 Figure 27C 、 Figure 27D 、 Figure 27E 、 Figure 27F As shown, the “downlink modulation signal existence interval 2751” includes the first time or a portion of the first time, and the “uplink modulation signal existence interval 2761” also includes the first time or a portion of the first time (see Figure 28 ). And, let, as Figure 28 As shown, the first time includes at least "time #1", "time #2" and "time #3".

[0613] like Figure 28 As shown, in "time #1" or a part of "time #1" in "downlink modulation signal existence interval 2751", there is "modulation signal 2801_1 of NR-UE1 sent to 1100_1". In addition, Figure 26 TRP1 of 1101_1 sends "modulated signal 2801_1 sent to NR-UE1 of 1100_1".

[0614] In "time #2" or a portion of "time #2" in "downlink modulated signal existence interval 2751", there is "modulated signal 2801_4 for NR-UE 4 of 1100_4". Figure 26 TRP1 of 1101_1 sends "modulated signal 2801_4 sent to NR-UE4 of 1100_4".

[0615] In "time #3" or a portion of "time #3" in "downlink modulated signal existence interval 2751", there is "modulated signal 2801_5 of NR-UE5 addressed to 1100_5". Figure 26 TRP1 of 1101_1 sends "modulated signal 2801_5 sent to NR-UE5 of 1100_5".

[0616] like Figure 28 As shown, in "time #1" or a part of "time #1" in "uplink modulated signal existence interval 2761", "transmission signal 2811_5 of NR-UE5 of 1100_5" exists. Figure 26 The NR-UE5 of 1100_5 sends the "transmission signal 2811_5 of the NR-UE5 of 1100_5".

[0617] In "time #2" or a portion of "time #2" in "uplink modulated signal existence interval 2761", "transmission signal 2811_4 of NR-UE 4 of 1100_4" exists. Figure 26 NR-UE4 of 1100_4 sends "transmission signal 2811_4 of NR-UE4 of 1100_4".

[0618] In "time #3" or a portion of "time #3" in "uplink modulated signal existence interval 2761", "transmission signal 2811_1 of NR-UE1 of 1100_1" exists. Figure 26 NR-UE1 of 1100_1 sends "transmission signal 2811_1 of NR-UE1 of 1100_1".

[0619] As described above, sometimes, the "downlink modulation signal sent by TRP1 of 1101_1" and the "uplink modulation signal sent by NR-UE to TRP2 of 1101_2" use "the same frequency or partially the same frequency" and exist at the same time.

[0620] However, there may be a first NR-UE that satisfies the following condition: "'The downlink modulation signal sent by TRP1 to the first NR-UE' and 'the uplink modulation signal sent by the first NR-UE to TRP2' exist at different times." In addition, this point is a communication method different from Implementation 1.

[0621] By adopting the above-mentioned method, self-interference can sometimes be reduced, thereby achieving the effect of improving the frequency utilization efficiency of the system.

[0622] In addition, it is also possible to switch in time between "the case where TRP1, TRP2, and NR-UE communicate as in Implementation 1" and "the case where TRP1, TRP2, and NR-UE communicate as in this implementation".

[0623] In addition, there may also be NR-UEs that "communicate with TRP1 and TRP2 as in Implementation Example 1" and NR-UEs that "communicate with TRP1 and TRP2 as in this implementation example."

[0624] exist Figure 26 It is assumed that the number of TRPs in the wireless system is 2, but it is not limited to this. The number of TRPs can be set to more than 1 or more than 2 for implementation. In addition, the number of NR-UEs can be set to more than 1 or more than 2 for implementation.

[0625] (Implementation 3)

[0626] In Embodiment 3, a modified example of Embodiment 1 and Embodiment 2 is described. The configuration and basic operations of the gNB and NR-UE have already been described in Embodiment 1, and therefore their description is omitted here.

[0627] Figure 29 An example of a wireless system in this embodiment is shown. Figure 29 As shown, for example, there are TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, NR-UE3 of 1100_3, NR-UE4 of 1100_4, and NR-UE5 of 1100_5. Figure 29 In the Figure 11 The same reference numerals are attached to the parts of the same operation, and some descriptions are omitted. Figure 29 In the description of FIG, for simplicity, descriptions of the transmit beam generated by performing transmit beamforming and the receive beam generated by performing receive beamforming are omitted. It should be noted that this embodiment can be implemented even without performing transmit beamforming or receive beamforming.

[0628] Set as, Figure 29 In the example, TRP1 of 1101_1 sends a modulated signal (DL: Downlink 2901_1) to NR-UE1 of 1100_1.

[0629] Then, NR-UE1 of 1100_1 receives the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0630] Assume that TRP1 of 1101_1 sends a modulated signal (DL: Downlink 2901_2) to NR-UE2 of 1100_2.

[0631] Then, NR-UE2 of 1100_2 receives the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0632] Assume that TRP1 of 1101_1 sends a modulated signal (DL: Downlink 2901_4) to NR-UE4 of 1100_4.

[0633] Then, NR-UE4 of 1100_4 receives the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0634] Assume that NR-UE1 of 1100_1 sends a modulated signal (UL: Uplink 2911_1) of TRP2 to 1101_2.

[0635] Then, TRP2 of 1101_2 receives the modulated signal sent by NR-UE1 of 1100_1 to TRP2.

[0636] Assume that NR-UE3 of 1100_3 sends a modulated signal of TRP2 to 1101_2 (UL: Uplink 2911_3).

[0637] Then, TRP2 of 1101_2 receives the modulated signal sent by NR-UE3 of 1100_3 to TRP2.

[0638] Assume that NR-UE5 of 1100_5 sends a modulated signal of TRP2 to 1101_2 (UL: Uplink 2911_5).

[0639] Then, TRP2 of 1101_2 receives the modulated signal sent by NR-UE5 of 1100_5 to TRP2.

[0640] exist Figure 29 In the example, NR-UE2 of 1100_2 sends the uplink modulation signal to TRP, but Figure 29 Not shown in the figure.

[0641] In addition, NR-UE4 of 1100_4 sends the uplink modulated signal to TRP, but Figure 29 Not shown in the figure.

[0642] exist Figure 29 In the example, NR-UE3 of 1100_3 receives the modulated signal of the downlink sent by TRP, but Figure 29 Not shown in the figure.

[0643] In addition, NR-UE5 of 1100_5 receives the modulated signal of the downlink sent by TRP, but Figure 29 Not shown in the figure.

[0644] Set as, Figure 29 The wireless system composed of at least "TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, NR-UE3 of 1100_3, NR-UE4 of 1100_4, and 1100_5" uses the first frequency (frequency band) for communication.

[0645] Figure 30A An example of the usage status of the first frequency (frequency band) on the time axis is shown. Figure 30A Shown Figure 29 An example of the status of the "modulated signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and the "modulated signal sent by TRP1 of 1101_1 to NR-UE2 of 1100_2" on the time axis. In addition, Figure 30A , the horizontal axis is time.

[0646] Set as, Figure 30A As shown, the "modulated signal 3001_1 sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and the "modulated signal 3001_2 sent by TRP1 of 1101_1 to NR-UE2 of 1100_2" exist at the first time.

[0647] Figure 30B 、 Figure 30C 、 Figure 30D 、 Figure 30E An example of the usage status of the first frequency (frequency band) on the time axis is shown. Figure 29 The status of "modulated signal 3001_1 sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and "modulated signal 3001_2 sent by TRP1 of 1101_1 to NR-UE2 of 1100_2" on the time axis is the same as that of "modulated signal 3001_1 sent by TRP1 of 1101_1 to NR-UE2 of 1100_2" on the time axis. Figure 30A Different examples. In addition, Figure 30B 、 Figure 30C 、 Figure 30D 、 Figure 30E , the horizontal axis is time.

[0648] like Figure 30B 、 Figure 30C 、 Figure 30D 、 Figure 30E As shown, at a certain time interval of the first time, there is a "modulated signal 3001_1 sent by TRP1 of 1101_1 and sent to NR-UE1 of 1100_1". In addition, at a certain time interval of the first time, there is a "modulated signal 3001_2 sent by TRP1 of 1101_1 and sent to NR-UE2 of 1100_2".

[0649] In addition, examples of the temporal configuration of "the modulated signal 3001_1 sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and "the modulated signal 3001_2 sent by TRP1 of 1101_1 to NR-UE2 of 1100_2" are not limited to Figure 30A 、 Figure 30B 、 Figure 30C 、 Figure 30D 、 Figure 30E As long as "the modulated signal 3001_1 sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and "the modulated signal 3001_2 sent by TRP1 of 1101_1 to NR-UE2 of 1100_2" exist at the same time, the configuration in any time is acceptable.

[0650] Therefore, if Figure 30A 、 Figure 30B 、 Figure 30C 、 Figure 30D 、 Figure 30EAs shown in the example, the "modulated signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and the "modulated signal sent by TRP1 of 1101_1 to NR-UE2 of 1100_2" are spatial division multiplexed (SDM).

[0651] The multiplexing method of "the modulated signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and "the modulated signal sent by TRP1 of 1101_1 to NR-UE4 of 1100_4" is explained.

[0652] Figure 31A An example of the usage status of the first frequency (frequency band) on the time axis is shown. Figure 31A Shown Figure 29 An example of the status of the "modulated signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and the "modulated signal sent by TRP1 of 1101_1 to NR-UE4 of 1100_4" on the time axis. In addition, Figure 31A , the horizontal axis is time.

[0653] In addition, let Figure 31A As shown, the "modulated signal 3001_1 sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" exists at the first time (or a certain time interval of the first time), and the "modulated signal 3001_4 sent by TRP1 of 1101_1 to NR-UE4 of 1100_4" exists at the second time.

[0654] Therefore, if Figure 31A As shown, the "modulation signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and the "modulation signal sent by TRP1 of 1101_1 to NR-UE4 of 1100_4" are time division multiplexed (TDM).

[0655] Figure 31B An example of usage status of frequencies including a first frequency (frequency band) 1201 is shown. Figure 31B Shown Figure 29 An example of the situation on the frequency axis of "the modulated signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and "the modulated signal sent by TRP1 of 1101_1 to NR-UE4 of 1100_4". Figure 31B In the figure, the horizontal axis is frequency.

[0656] In addition, let Figure 31B As shown, the “modulated signal 3001_1 sent by TRP1 of 1101_1 to NR-UE1 of 1100_1” exists in the first frequency (frequency band) 1201, and the “modulated signal 3001_4 sent by TRP1 of 1101_1 to NR-UE4 of 1100_4” exists in the second frequency (frequency band) 1202. Therefore, as Figure 31B As shown, the "modulation signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and the "modulation signal sent by TRP1 of 1101_1 to NR-UE4 of 1100_4" are frequency division multiplexed (FDM).

[0657] As described above, TDM or FDM can be used for the "modulation signal sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and the "modulation signal sent by TRP1 of 1101_1 to NR-UE4 of 1100_4".

[0658] right Figure 29 The following describes an example of the relationship between the "modulated signal sent by NR-UE1 of 1100_1" and the "modulated signal sent by NR-UE3 of 1100_3" in the wireless system.

[0659] Figure 32A An example of the usage status of the first frequency (frequency band) on the time axis is shown. Figure 32A Shown Figure 29 An example of the status of the "modulated signal transmitted by NR-UE1 of 1100_1" and the "modulated signal transmitted by NR-UE3 of 1100_3" on the time axis. In addition, Figure 32A In , the horizontal axis is time. Let, Figure 32A As shown, the “modulated signal 3201_1 transmitted by NR-UE1 of 1100_1” and the “modulated signal 3201_3 transmitted by NR-UE3 of 1100_3” exist at the first time.

[0660] Figure 32B 、 Figure 32C 、 Figure 32D 、 Figure 32E An example of the usage status of the first frequency (frequency band) on the time axis is shown. Figure 29 The status of the "modulated signal 3201_1 transmitted by NR-UE1 of 1100_1" and the "modulated signal 3201_3 transmitted by NR-UE3 of 1100_3" on the time axis Figure 32AIn addition, Figure 32B 、 Figure 32C 、 Figure 32D 、 Figure 32E , the horizontal axis is time.

[0661] like Figure 32B 、 Figure 32C 、 Figure 32D 、 Figure 32E As shown, in a certain time interval of the first time, there is a "modulated signal 3201_1 sent by NR-UE1 of 1100_1". In addition, in a certain time interval of the first time, there is a "modulated signal 3201_3 sent by NR-UE3 of 1100_3".

[0662] In addition, examples of the temporal arrangement of "the modulated signal 3201_1 transmitted by the NR-UE1 of 1100_1" and "the modulated signal 3201_3 transmitted by the NR-UE3 of 1100_3" are not limited to Figure 32A 、 Figure 32B 、 Figure 32C 、 Figure 32D 、 Figure 32E As long as the "modulated signal 3201_1 sent by NR-UE1 of 1100_1" and the "modulated signal 3201_3 sent by NR-UE3 of 1100_3" exist at the same time, the configuration in any time is acceptable.

[0663] Therefore, if Figure 32A 、 Figure 32B 、 Figure 32C 、 Figure 32D 、 Figure 32E As shown in the example, the "modulated signal 3201_1 transmitted by NR-UE1 of 1100_1" and the "modulated signal 3201_3 transmitted by NR-UE3 of 1100_3" are spatially divided multiplexed (SDM).

[0664] The multiplexing method of "modulated signal 3201_1 transmitted by NR-UE1 of 1100_1" and "modulated signal 3201_5 transmitted by NR-UE5 of 1100_5" is described.

[0665] Figure 33A An example of the usage status of the first frequency (frequency band) on the time axis is shown. Figure 33A Shown Figure 29 An example of the status of "modulated signal 3201_1 transmitted by NR-UE1 of 1100_1" and "modulated signal 3201_5 transmitted by NR-UE5 of 1100_5" on the time axis. In addition, Figure 33A , the horizontal axis is time.

[0666] In addition, let Figure 33A As shown, the "modulated signal 3201_1 sent by NR-UE1 of 1100_1" exists at the first time (or a certain time interval of the first time), and the "modulated signal 3201_5 sent by NR-UE5 of 1100_5" exists at the second time.

[0667] Therefore, if Figure 33A As shown in the example, the "modulated signal 3201_1 transmitted by NR-UE1 of 1100_1" and the "modulated signal 3201_5 transmitted by NR-UE5 of 1100_5" are time division multiplexed (TDM).

[0668] Figure 33B An example of a situation including frequencies of a first frequency (frequency band) 1201 is shown. Figure 33B Shown Figure 29 An example of the situation of "modulation signal transmitted by NR-UE1 of 1100_1" and "modulation signal transmitted by NR-UE5 of 1100_5" on the frequency axis. In addition, Figure 33B In the figure, the horizontal axis is frequency.

[0669] In addition, let Figure 33B As shown, the “modulated signal 3201_1 sent by NR-UE1 of 1100_1” exists in the first frequency (frequency band) 1201, and the “modulated signal 3201_5 sent by NR-UE5 of 1100_5” exists in the third frequency (frequency band) 1203.

[0670] Therefore, if Figure 33B As shown in the example, the "modulated signal 3201_1 transmitted by NR-UE1 of 1100_1" and the "modulated signal 3201_5 transmitted by NR-UE5 of 1100_5" are frequency division multiplexed (FDM).

[0671] As described above, TDM or FDM can be used for the "modulation signal sent by NR-UE1 of 1100_1" and the "modulation signal sent by NR-UE5 of 1100_5".

[0672] As described above, the NR-UE of 1101_1 sometimes uses "the same frequency or partially the same frequency" to receive downlink signals and send uplink signals at the same time, and "TRP1 implements one or more of SDM, TDM, and FDM on signals sent to multiple terminals" and "multiple terminals implement one or more of SDM, TDM, and FDM on uplink signals."

[0673] By doing so, self-interference can sometimes be reduced, thereby improving the frequency utilization efficiency of the system. In addition, flexible access of NR-UE becomes possible, which can achieve the effect of improving transmission speed and / or reception quality.

[0674] exist Figure 29 The number of TRPs in the wireless system is set to 2, but it is not limited to this, and the number of TRPs can be set to more than 1 or more than 2 for implementation.

[0675] In addition, Figure 29 The number of NR-UEs in the wireless system is set to 5, but is not limited to this, and the number of NR-UEs can be set to more than 1 or more than 2 for implementation.

[0676] (Implementation 4)

[0677] In Embodiment 4, a modified example of Embodiment 1 is described. The configuration and basic operations of the gNB and NR-UE have already been described in Embodiment 1, and therefore their description is omitted here.

[0678] Figure 34A 、 Figure 35A An example of a wireless system in this embodiment is shown. Figure 34A 、 Figure 35A As shown, for example, there are TRP1 of 1101_1, TRP2 of 1101_2, and NR-UE1 of 1100_1. Figure 34A 、 Figure 35A In the Figure 11 The same reference numerals are assigned to parts that perform the same operations, and description thereof will be omitted.

[0679] Set as, Figure 34A In the example, TRP1 of 1101_1 generates a transmit beam 3440_1 and uses the transmit beam 3440_1 to transmit a modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0680] Therefore, NR-UE1 of 1100_1 generates receiving beam 3430_1 and uses receiving beam 3430_1 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0681] In addition, it is assumed that NR-UE1 of 1100_1 generates a transmission beam 3420_2 and uses the transmission beam 3420_2 to transmit a modulated signal (UL: Uplink) of TRP2 addressed to 1101_2.

[0682] Therefore, TRP2 of 1101_2 generates receiving beam 3450_2 and uses receiving beam 3450_2 to receive the modulated signal sent by NR-UE1 of 1100_1 to TRP2 of 1101_2.

[0683] Figure 34B Shown Figure 34A This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2 and NR-UE1 of 1100_1" on the frequency axis. Figure 34B 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0684] The TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit the modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by the NR-UE1 of 1100_1, for example. In addition, the TRP1 of 1101_1 can be as follows: Figure 34B As shown, communication using TDD or FDD can be performed at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 34B Differently, communication is not performed at frequencies (frequency bands) other than the first frequency (frequency band) 1201 .

[0685] The TRP2 of 1101_2 uses the first frequency (band) 1201 for receiving the modulated signal for uplink. At this time, the TRP2 of 1101_2 receives the modulated signal of the first frequency (band) 1201 transmitted by the NR-UE1 of 1100_1. Alternatively, it may be as follows: Figure 34B As shown, TRP2 of 1101_2 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201, or may be Figure 34B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, TRP2 of 1101_2 does not communicate.

[0686] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by TRP2 of 1101_2, for example. In addition, NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by TRP1 of 1101_1. In addition, it can be, for example, Figure 34BAs shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 34B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0687] exist Figure 34B , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD have been described, so their explanation is omitted.

[0688] Set as, Figure 35A In the example, TRP2 of 1101_2 generates a transmit beam 3440_2 and uses the transmit beam 3440_2 to transmit a modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0689] Therefore, NR-UE1 of 1100_1 generates receiving beam 3430_2 and uses receiving beam 3430_2 to receive the modulated signal sent by TRP2 of 1101_2 to NR-UE1.

[0690] In addition, it is assumed that NR-UE1 of 1100_1 generates a transmission beam 3420_1 and uses the transmission beam 3420_1 to transmit a modulated signal (UL: Uplink) addressed to TRP1 of 1101_1.

[0691] Therefore, TRP1 of 1101_1 generates a receiving beam 3450_1 and uses the receiving beam 3450_1 to receive the modulated signal sent by NR-UE1 of 1100_1 to TRP1 of 1101_1.

[0692] Figure 35B Shown Figure 35A This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2 and NR-UE1 of 1100_1" on the frequency axis. Figure 35B 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0693] The TRP2 of 1101_2 uses the first frequency (band) 1201 to transmit the modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP2 of 1101_2 is received by the NR-UE1 of 1100_1, for example. In addition, the TRP2 of 1101_2 can be as follows: Figure 35B As shown, communication using TDD or FDD can be performed at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 35B Differently, communication is not performed at frequencies (frequency bands) other than the first frequency (frequency band) 1201 .

[0694] The TRP1 of 1101_1 uses the first frequency (band) 1201 for receiving the modulated signal for uplink. At this time, the TRP1 of 1101_1 receives the modulated signal of the first frequency (band) 1201 transmitted by the NR-UE1 of 1100_1. Alternatively, it may be as follows: Figure 35B As shown, TRP1 of 1101_1 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201, or may perform communication using FDD. Figure 35B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201 , TRP1 of 1101_1 does not perform communication.

[0695] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by TRP1 of 1101_1, for example. In addition, NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by TRP2 of 1101_2. In addition, it can be, for example, Figure 35B As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 35B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0696] exist Figure 35B , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD have been described, so their explanation is omitted.

[0697] In this embodiment, the NR-UE1 of 1100_1 switches in time Figure 34A Status and Figure 35A An example of its time situation is shown in Figure 36A .

[0698] Figure 36A Shown Figure 34A 、 Figure 35A This is an example of the transmission status of "TRP1 of 1101_1, TRP2 of 1101_2 and NR-UE1 of 1100_1" on the time axis. Figure 36A In the diagram, the horizontal axis is the time axis.

[0699] like Figure 36A As shown, TRP1 of 1101_1 sends signal 3601_1 to NR-UE1 of 1100_1 at the first time. Also, NR-UE1 of 1100_1 sends signal 3611_1 to TRP2 of 1101_2 at the first time. That is, the communication status at the first time is Figure 34A The communication status is shown.

[0700] At the second time, TRP2 of 1101_2 sends a signal 3621_2 to NR-UE1 of 1100_1. Also, NR-UE1 of 1100_1 sends a signal 3611_2 to TRP1 of 1101_1. That is, the communication status at the second time is Figure 35A The communication status is shown.

[0701] By doing so, the NR-UE sends modulated signals to multiple TRPs and receives modulated signals sent by multiple TRPs, thereby achieving spatial diversity effects in both uplink and downlink. This can improve transmission quality.

[0702] use Figure 36B 、 Figure 36C 、 Figure 36D 、 Figure 36E Description relative to Figure 36A , first time, second time and Figure 36A Different examples.

[0703] Figure 36B 、 Figure 36C 、 Figure 36D 、 Figure 36E is relative to Figure 36A , "first time" and "second time" are different examples. In addition, Figure 36B , the horizontal axis is time.

[0704] exist Figure 36B 、 Figure 36C 、 Figure 36D 、 Figure 36E In , let "TRP X" be "TRP1", "TRP Y" be "TRP2", and "Zth time" be "first time". Figure 36A The first time communication, Figure 36B or Figure 36C or Figure 36D or Figure 36E "communication.

[0705] Therefore, at the first time, TRP1 of 1101_1 sends a signal 3681 to NR-UE1 of 1100_1, and NR-UE1 of 1100_1 sends a signal 3691 to TRP Y, that is, a signal to TRP2 of 1101_2.

[0706] In addition, Figure 36B 、 Figure 36C 、 Figure 36D 、 Figure 36E In , "TRP X" is set to "TRP2", "TRP Y" is set to "TRP1", and "Zth time" is set to "second time". Figure 36A The second time communication, Figure 36B or Figure 36C or Figure 36D or Figure 36E "communication.

[0707] Therefore, at the second time, TRP2 of 1101_2 sends a signal 3681 to NR-UE1 of 1100_1, and NR-UE1 of 1100_1 sends a signal 3691 to TRP Y, that is, sends a signal to TRP1 of 1101_1.

[0708] In addition, the time configuration of the signal 3681 sent to the NR-UE and the signal 3691 sent to the TRP Y is not limited to Figure 36A 、 Figure 36B 、 Figure 36C 、 Figure 36D 、 Figure 36E For example, it is sufficient as long as the signal 3681 sent to NR-UE and the signal 3691 sent to TRP Y partially overlap in time.

[0709] In addition, about Figure 36A The configuration of the time when "TRP1 of 1101_1 sends a downlink signal, and NR-UE1 of 1100_1 sends an uplink signal to TRP2 of 1101_2" and the time when "TRP2 of 1101_2 sends a downlink signal, and NR-UE1 of 1100_1 sends an uplink signal to TRP1 of 1101_1" is not limited to Figure 36A Examples can be configured arbitrarily.

[0710] exist Figure 36A In the example, the "signal 3611_1 sent to TRP2 of 1101_2, and the signal 3611_2 sent to TRP1 of 1101_1" sent by NR-UE1 of 1100_1 may also include the same data. In addition, the "signal 3611_1 sent to TRP2 of 1101_2, and the signal 3611_2 sent to TRP1 of 1101_1" may also be a structure with the same content although "there are differences in conditions such as different compression rates and different structures." In addition, the "signal 3611_1 sent to TRP2 of 1101_2, and the signal 3611_2 sent to TRP1 of 1101_1" may also include some of the same data. URLLC (Ultra-reliable and low-latency communication) can be implemented in the above manner. In addition, the structure of "the signal 3611_1 sent to the TRP2 of 1101_2 and the signal 3611_2 sent to the TRP1 of 1101_1" is not limited to Figure 36A The structure can also be used Figure 36B 、 Figure 36C 、 Figure 36D 、 Figure 36E The structure described.

[0711] In addition, Figure 36A In the example, the "signal 3601_1 sent to the NR-UE1 of 1100_1, the signal 3621_2 sent to the NR-UE1 of 1100_1" sent by the TRP1 of 1101_1 or the TRP2 of 1101_2 may also include the same data. In addition, the "signal 3601_1 sent to the NR-UE1 of 1100_1, the signal 3621_2 sent to the NR-UE1 of 1100_1" may also be a structure with the same content although "there are differences in conditions such as different compression rates and different structures." In addition, the "signal 3601_1 sent to the NR-UE1 of 1100_1, the signal 3621_2 sent to the NR-UE1 of 1100_1" may also include a part of the same data. URLLC can be implemented in the above manner. In addition, the structure of the "signal 3601_1 sent to the NR-UE1 of 1100_1, the signal 3621_2 sent to the NR-UE1 of 1100_1" is not limited to Figure 36A The structure can also be used Figure 36B 、 Figure 36C 、 Figure 36D 、 Figure 36E The structure described.

[0712] in addition, Figure 34A 、 Figure 35ANR-UE1 of 1100_1 communicates with TRP1 of 1101_1 and TRP2 of 1101_2, but NR-UE1 of 1100_1 can also communicate with more than two TRPs. For example, when TRP3 exists, there may be a time when "TRP3 sends a signal to NR-UE1 of 1100_1, and NR-UE1 of 1100_1 sends a signal to TRP". The same is true when there are further other TRPs.

[0713] Next, another example will be described.

[0714] Figure 37A 、 Figure 38A An example of a wireless system in this embodiment is shown. Figure 37A 、 Figure 38A As shown, for example, there are TRP1 of 1101_1, TRP2 of 1101_2, and NR-UE1 of 1100_1. Figure 37A 、 Figure 38A In the Figure 11 The same reference numerals are assigned to parts that perform the same operations, and description thereof will be omitted.

[0715] Set as, Figure 37A In the example, TRP1 of 1101_1 generates a transmit beam 3721_1 and uses the transmit beam 3721_1 to transmit a modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0716] Therefore, NR-UE1 of 1100_1 generates receiving beam 3730_1 and uses receiving beam 3730_1 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0717] In addition, it is assumed that NR-UE1 of 1100_1 generates a transmission beam 3720_1 and uses the transmission beam 3720_1 to transmit a modulated signal (UL: Uplink) addressed to TRP1 of 1101_1.

In addition, Figure 38C 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0739] The TRP1 of 1101_1 uses the second frequency (frequency band) 1202 for receiving the modulation signal for uplink and for transmitting the modulation signal for downlink.

[0741] NR-UE1 of 1100_1 uses first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by, for example, TRP2 of 1101_2.

[0742] exist Figure 38C, the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD have been described, so their explanation is omitted.

[0743] In this embodiment, the NR-UE1 of 1100_1 switches in time Figure 37A Status and Figure 38A An example of its time situation is shown in Figure 39A .

[0744] Figure 39A An example of the transmission status of "TRP1 of 1101_1, TRP2 of 1101_2 and NR-UE1 of 1100_1" is shown. Figure 39A In the diagram, the horizontal axis is the time axis.

[0745] like Figure 39A As shown, TRP1 of 1101_1 sends signal 3901_1 to NR-UE1 of 1100_1 at the first time. Also, NR-UE1 of 1100_1 sends signal 3911_1 to TRP1 of 1101_1 at the first time. That is, the communication status at the first time is Figure 37A The communication status is shown.

[0746] At the second time, TRP2 of 1101_2 sends signal 3921_2 to NR-UE1 of 1100_1. Also, NR-UE1 of 1100_1 sends signal 3911_2 to TRP2 of 1101_2 at the second time. That is, the communication status at the second time is Figure 38A The communication status is shown.

[0747] By adopting the above method, the NR-UE sends modulated signals to multiple TRPs and receives modulated signals sent by multiple TRPs, thereby achieving spatial diversity effects in both uplink and downlink. As a result, the transmission quality can be improved.

[0748] use Figure 39B 、 Figure 39C 、 Figure 39D 、 Figure 39E illustrate Figure 39A The first time, the second time and Figure 39A Different examples.

[0749] Figure 39B 、 Figure 39C 、 Figure 39D 、 Figure 39E yes Figure 39AThe "first time", "second time" and Figure 39A Different examples. In addition, Figure 39B , the horizontal axis is time.

[0750] In addition, Figure 39B 、 Figure 39C 、 Figure 39D 、 Figure 39E In , let "TRP X" be "TRP1" and "the Zth time" be "the first time". Figure 39A The first time communication, Figure 39B or Figure 39C or Figure 39D or Figure 39E "communication.

[0751] Therefore, at the first time, TRP1 of 1101_1 sends a signal 3981 to NR-UE1 of 1100_1, and NR-UE1 of 1100_1 sends a signal 3991 to TRP X, that is, sends a signal to TRP1 of 1101_1.

[0752] In addition, Figure 39B 、 Figure 39C 、 Figure 39D 、 Figure 39E In , "TRP X" is set to "TRP2", and "Zth time" is set to "second time". Figure 39A The second time communication, Figure 39B or Figure 39C or Figure 39D or Figure 39E "communication.

[0753] Therefore, at the second time, TRP2 of 1101_2 sends a signal 3981 to NR-UE1 of 1100_1, and NR-UE1 of 1100_1 sends a signal 3991 to TRP X, that is, a signal to TRP2 of 1101_2.

[0754] In addition, the time configuration of the signal 3981 sent to the NR-UE and the signal 3991 sent to the TRP X is not limited to Figure 39A 、 Figure 39B 、 Figure 39C 、 Figure 39D 、 Figure 39E For example, it is sufficient as long as the signal 3981 sent to NR-UE and the signal 3991 sent to TRP X partially overlap in time.

[0755] In addition, about Figure 39AThe configuration of the time when "TRP1 of 1101_1 sends a downlink signal, and NR-UE1 of 1100_1 sends an uplink signal to TRP1 of 1101_1" and the time when "TRP2 of 1101_2 sends a downlink signal, and NR-UE1 of 1100_1 sends an uplink signal to TRP2 of 1101_2" are not limited to Figure 39A Examples can be configured arbitrarily.

[0756] exist Figure 39A In the example, the "signal 3911_1 sent to TRP1 of 1101_1, the signal 3911_2 sent to TRP2 of 1101_2" sent by NR-UE1 of 1100_1 may also include the same data. In addition, the "signal 3911_1 sent to TRP1 of 1101_1, the signal 3911_2 sent to TRP2 of 1101_2" may also be a structure with the same content although "there are differences in conditions such as different compression rates and different structures." In addition, the "signal 3911_1 sent to TRP1 of 1101_1, the signal 3911_2 sent to TRP2 of 1101_2" may also include a portion of the same data. URLLC can be implemented in the above manner. In addition, the structure of the "signal 3911_1 sent to TRP1 of 1101_1, the signal 3911_2 sent to TRP2 of 1101_2" is not limited to Figure 39A The structure can also be used Figure 39B 、 Figure 39C 、 Figure 39D 、 Figure 39E The structure described.

[0757] In addition, Figure 39A In the example, the "signal 3901_1 sent to the NR-UE1 of 1100_1, the signal 3921_2 sent to the NR-UE1 of 1100_1" sent by the TRP1 of 1101_1 or the TRP2 of 1101_2 may also include the same data. In addition, the "signal 3901_1 sent to the NR-UE1 of 1100_1, the signal 3921_2 sent to the NR-UE1 of 1100_1" may also be a structure with the same content although "there are differences in conditions such as different compression rates and different structures." In addition, the "signal 3901_1 sent to the NR-UE1 of 1100_1, the signal 3921_2 sent to the NR-UE1 of 1100_1" may also include a part of the same data. URLLC can be implemented in the above manner. In addition, the structure of the "signal 3901_1 sent to the NR-UE1 of 1100_1, the signal 3921_2 sent to the NR-UE1 of 1100_1" is not limited to Figure 39A The structure can also be used Figure 39B 、 Figure 39C 、 Figure 39D 、 Figure 39E The structure described.

[0758] in addition, Figure 37A 、 Figure 38A NR-UE1 of 1100_1 communicates with TRP1 of 1101_1 and TRP2 of 1101_2, but NR-UE1 of 1100_1 can also communicate with more than two TRPs. For example, when TRP3 exists, there may be a time when "TRP3 sends a signal to NR-UE1 of 1100_1, and NR-UE1 of 1100_1 sends a signal to TRP3." The same is true when there are further other TRPs.

[0759] Next, another example will be described.

[0760] Figure 34A 、 Figure 35A 、 Figure 40A An example of a wireless system in this embodiment is shown. Figure 34A 、 Figure 35A 、 Figure 40A As shown, for example, there are TRP1 of 1101_1, TRP2 of 1101_2, and NR-UE1 of 1100_1. Figure 34A 、 Figure 35A 、 Figure 40A In the Figure 11 The same reference numerals are assigned to parts that perform the same operations, and part of the description is omitted.

[0761] about Figure 34A 、 Figure 34B The explanation has been given, so the explanation is omitted. Figure 35A 、 Figure 35B Since the explanation has been given, the explanation is omitted.

[0762] Figure 40A NR-UE1 of 1100_1 communicates with TRP1 of 1101_1 and / or TRP2 of 1101_2.

[0763] When the NR-UE1 of 1100_1 communicates with the TRP1 of 1101_1, the NR-UE1 of 1100_1 sends a modulated signal to the TRP1 of 1101_1, and the TRP1 of 1101_1 sends a modulated signal (4001_1) to the NR-UE1 of 1100_1.

[0764] When NR-UE1 of 1100_1 communicates with TRP2 of 1101_2, NR-UE1 of 1100_1 sends a modulated signal to TRP2 of 1101_2, and TRP2 of 1101_2 sends a modulated signal (4001_2) to NR-UE2 of 1100_2.

[0765] Figure 40B Shown Figure 40A This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2 and NR-UE1 of 1100_1" on the frequency axis. Figure 40B 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0766] When the NR-UE1 of 1100_1 communicates with the TRP1 of 1101_1, communication is performed using "TDD or FDD", so the modulated signal sent by the NR-UE1 of 1100_1 to the TRP1 of 1101_1 and / or the modulated signal sent by the TRP1 of 1101_1 to the NR-UE1 of 1100_1 exists in the first frequency (frequency band) 1201.

[0767] Furthermore, the TRP1 of 1101_1 receives the modulated signal sent by the NR-UE1 of 1100_1 and addressed to the TRP1 of 1101_1, and the NR-UE1 of 1100_1 receives the modulated signal sent by the TRP1 of 1101_1 and addressed to the NR-UE1 of 1100_1.

[0768] When the NR-UE1 of 1100_1 communicates with the TRP2 of 1101_2, communication is performed using "TDD or FDD", so the modulated signal sent by the NR-UE1 of 1100_1 to the TRP1 of 1101_1 and / or the modulated signal sent by the TRP2 of 1101_2 to the NR-UE1 of 1100_1 exists in the first frequency (frequency band) 1201.

[0769] Furthermore, TRP2 of 1101_2 receives the modulated signal sent by NR-UE1 of 1100_1 to TRP2 of 1101_2, and NR-UE1 of 1100_1 receives the modulated signal sent by TRP2 of 1101_2 to NR-UE1 of 1100_1.

[0770] Alternatively, it could be, Figure 40B As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 40BDifferently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0771] It can be, for example Figure 40B As shown, TRP1 of 1101_1 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 40B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201 , TRP1 of 1101_1 does not perform communication.

[0772] It can be, for example Figure 40B As shown, TRP1 of 1101_1 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201.

[0835] Figure 43A An example of a wireless system in this embodiment is shown. Assume that Figure 43A In the example, TRP1 of 1101_1 sends a modulated signal (DL: Downlink 4302_1) to NR-UE1 of 1100_1.

[0836] Then, NR-UE1 of 1100_1 receives the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0837] In addition, it is assumed that NR-UE1 of 1100_1 sends a modulated signal of TRP2 (UL: Uplink 4301_2) to 1101_2.

[0838] Therefore, TRP2 of 1101_2 receives the modulated signal sent by NR-UE1 of 1100_1 to TRP2 of 1101_2.

[0839] Assume that NR-UE1 of 1100_1 sends a modulated signal of TRP3 to 1101_3 (UL: Uplink 4301_3).

[0840] Therefore, TRP3 of 1101_3 receives the modulated signal sent by NR-UE1 of 1100_1 to TRP3 of 1101_3.

[0841] In addition, other uplink transmission and reception and downlink transmission and reception may also exist.

[0842] Figure 43B Shown Figure 43A This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2, TRP3 of 1101_3 and NR-UE1 of 1100_1" on the frequency axis. Figure 43B 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0843] The TRP1 of 1101_1 uses the first frequency (frequency band) 1201 to transmit the modulated signal to the NR-UE1 of 1100_1. Therefore, the NR-UE1 of 1100_1 receives the signal. Alternatively, it may be, for example Figure 43B As shown, TRP1 of 1101_1 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201, or may perform communication using FDD. Figure 43B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201 , TRP1 of 1101_1 does not perform communication.

[0844] TRP2 of 1101_2 uses the first frequency (band) 1201 for receiving uplink modulated signals. Therefore, NR-UE1 of 1100_1 uses the first frequency (band) 1201 to send uplink modulated signals to TRP2 of 1101_2. In addition, TRP2 of 1101_2 can be as follows: Figure 43BAs shown, communication using TDD or FDD can be performed at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 43B Differently, communication is not performed at frequencies (frequency bands) other than the first frequency (frequency band) 1201 .

[0845] TRP3 of 1101_3 uses the first frequency (band) 1201 for receiving uplink modulated signals. Therefore, NR-UE1 of 1100_1 uses the first frequency (band) 1201 to send uplink modulated signals to TRP3 of 1101_3. In addition, TRP3 of 1101_3 can be as follows: Figure 43B As shown, communication using TDD or FDD can be performed at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 43B Differently, communication is not performed at frequencies (frequency bands) other than the first frequency (frequency band) 1201 .

[0846] The NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving the modulation signal for the downlink and for sending the modulation signal for the uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 sent by the NR-UE1 of 1100_1 is received by, for example, the TRP2 of 1101_2. And, the modulation signal of the first frequency (frequency band) 1201 sent by the NR-UE1 of 1100_1 is received by, for example, the TRP3 of 1101_3. In addition, the NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 sent by the TRP1 of 1101_1. In addition, it can be, as Figure 43B As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 43B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0847] exist Figure 43B , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD have been described, so their explanation is omitted.

[0848] Figure 43C Shown Figure 43A In the example, “TRP1 of 1101_1, TRP2 of 1101_2, TRP3 of 1101_3 and NR-UE1 of 1100_1” Figure 43BThis is an example of the transmission status of "TRP1 of 1101_1, NR-UE1 of 1100_1" when using the frequency. Figure 43C In the diagram, the horizontal axis is the time axis.

[0849] like Figure 43C As shown, NR-UE1 of 1100_1 sends the modulation signal 4351_2 of TRP2 to 1101_2 and the modulation signal 4351_3 of TRP3 to 1101_3 at the first time. Figure 43B As described, the modulated signal 4351_2 of TRP2 sent to 1101_2 and the modulated signal 4351_3 of TRP3 sent to 1101_3 exist in the first frequency (frequency band) 1201. In other words, the NR-UE1 of 1100_1 implements spatial division multiplexing (SDM).

[0850] In addition, TRP1 of 1101_1 sends the modulated signal 4391_1 to NR-UE1 of 1100_1 at the first time. Figure 43B As described, the modulated signal 4391_1 sent to NR-UE1 1100_1 exists in the first frequency (frequency band) 1201.

[0851] Should be explained, Figure 43C This is just an example. The modulated signal 4351_2 of TRP2 sent to 1101_2 may also exist outside the first time. In addition, the modulated signal 4351_3 of TRP3 sent to 1101_3 may also exist outside the first time. In addition, the modulated signal 4391_1 of NR-UE1 sent to 1100_1 may also exist outside the first time.

[0852] By adopting the above method, NR-UE uses SDM to send modulated signals and communicate with TRP, thereby achieving the effect of improving transmission efficiency.

[0853] Figure 44A An example of a wireless system in this embodiment is shown. Assume that Figure 44A In the example, TRP1 of 1101_1 sends a modulated signal (DL: Downlink 4302_1) to NR-UE1 of 1100_1.

[0854] Then, NR-UE1 of 1100_1 receives the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0855] In addition, it is assumed that NR-UE1 of 1100_1 sends a modulated signal of TRP2 (UL: Uplink 4301_2) to 1101_2.

[0856] Therefore, TRP2 of 1101_2 receives the modulated signal sent by NR-UE1 of 1100_1 to TRP2 of 1101_2.

[0857] Assume that TRP3 of 1101_3 sends a modulated signal (DL: Downlink 4302_3) to NR-UE1 of 1100_1.

[0858] Therefore, NR-UE1 of 1100_1 receives the modulated signal sent by TRP3 of 1101_3 to NR-UE1.

[0859] In addition, other uplink transmission and reception and downlink transmission and reception may also exist.

[0862] TRP2 of 1101_2 uses the first frequency (band) 1201 for receiving uplink modulated signals. Therefore, NR-UE1 of 1100_1 uses the first frequency (band) 1201 to send uplink modulated signals to TRP2 of 1101_2. In addition, TRP2 of 1101_2 can be as follows: Figure 44B As shown, communication using TDD or FDD can be performed at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 44B Differently, communication is not performed at frequencies (frequency bands) other than the first frequency (frequency band) 1201 .

[0863] The TRP3 of 1101_3 uses the first frequency (band) 1201 to transmit the modulated signal to the NR-UE1 of 1100_1. Therefore, the NR-UE1 of 1100_1 receives the signal. Alternatively, it may be, for example Figure 44B As shown, TRP3 of 1101_3 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201, or can be Figure 44B Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, TRP3 of 1101_3 does not communicate.

[0864] The NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving the modulation signal for the downlink and for sending the modulation signal for the uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 sent by the NR-UE1 of 1100_1 is received by the TRP2 of 1101_2, for example. In addition, the NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 sent by the TRP1 of 1101_1. In addition, the NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 sent by the TRP3 of 1101_3.

That is, spatial division multiplexing (SDM) is implemented.

[0868] In addition, NR-UE1 of 1100_1 sends the modulated signal 4491_2 to TRP2 of 1101_2 at the first time. Figure 44B As described, the modulated signal 4491_2 of TRP2 sent to 1101_2 exists in the first frequency (frequency band) 1201.

However, the structures of the various devices are not limited to those described above. Furthermore, the communication methods described in this embodiment are merely examples and can be combined with or modified from other embodiments.

[0912] (Implementation 5)

[0913] In Embodiment 5, a modified example of Embodiment 1 and the like is described. The configuration and basic operations of the gNB and NR-UE have already been described in Embodiment 1, and therefore their description is omitted here.

[0914] Figure 47 An example of a wireless system in this embodiment is shown. Figure 47 As shown, for example, there are TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, and NR-UE3 of 1100_3. Figure 47 In the Figure 11 The same reference numerals are assigned to parts that perform the same operations, and part of the description is omitted.

[0915] Set as, Figure 47 In the example, TRP1 of 1101_1 generates transmit beam 4721_1 and uses transmit beam 4721_1 to transmit the modulated signal (DL: Downlink) to NR-UE1 of 1100_1.

[0916] Therefore, NR-UE1 of 1100_1 generates receiving beam 4731_1 and uses receiving beam 4731_1 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE1.

[0917] In addition, it is assumed that NR-UE1 of 1100_1 generates transmission beam 4741_1 and uses transmission beam 4741_1 to transmit the modulated signal (UL: Uplink) of TRP2 sent to 1101_2.

[0918] Therefore, TRP2 of 1101_2 generates receiving beam 4751_1 and uses receiving beam 4751_1 to receive the modulated signal sent by NR-UE1 of 1100_1 to TRP2 of 1101_2.

[0919] Assume that TRP1 of 1101_1 generates transmit beam 4721_2 and uses transmit beam 4721_2 to transmit a modulated signal (DL: Downlink) to NR-UE2 of 1100_2.

[0920] Therefore, NR-UE2 of 1100_2 generates receiving beam 4731_2 and uses receiving beam 4731_2 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE2.

[0921] In addition, it is assumed that NR-UE2 of 1100_2 generates transmission beam 4741_2 and uses transmission beam 4741_2 to transmit the modulated signal (UL: Uplink) of TRP2 sent to 1101_2.

[0922] Therefore, TRP2 of 1101_2 generates receiving beam 4751_2 and uses receiving beam 4751_2 to receive the modulated signal sent by NR-UE2 of 1100_2 to TRP2 of 1101_2.

[0923] Assume that TRP1 of 1101_1 generates transmission beam 4721_3 and uses transmission beam 4721_3 to transmit a modulated signal (DL: Downlink) to NR-UE3 of 1100_3.

[0924] Therefore, NR-UE3 of 1100_3 generates receiving beam 4731_3 and uses receiving beam 4731_3 to receive the modulated signal sent by TRP1 of 1101_1 to NR-UE3.

[0925] In addition, it is assumed that NR-UE3 of 1100_3 generates transmission beam 4741_3 and uses transmission beam 4741_3 to transmit the modulated signal (UL: Uplink) of TRP2 sent to 1101_2.

[0926] Therefore, TRP2 of 1101_2 generates receiving beam 4751_3 and uses receiving beam 4751_3 to receive the modulated signal sent by NR-UE3 of 1100_3 to TRP2 of 1101_2.

[0927] Figure 48A Shown Figure 47 This is an example of the communication status of "TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, and NR-UE3 of 1100_3" on the frequency axis. Figure 48A 12 , the same reference numerals are given to portions performing the same operations as in FIG12 , and the horizontal axis represents frequency.

[0928] The TRP1 of 1101_1 uses the first frequency (band) 1201 to transmit a modulated signal for downlink. At this time, the modulated signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1 is received by, for example, the NR-UE1 of 1100_1, the NR-UE2 of 1100_2, and the NR-UE3 of 1100_3. In addition, the TRP1 of 1101_1 can be as follows: Figure 48A As shown, communication using TDD or FDD can be performed at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 48A Differently, communication is not performed at frequencies (frequency bands) other than the first frequency (frequency band) 1201 .

[0929] The TRP2 of 1101_2 uses the first frequency (frequency band) 1201 for receiving the modulated signal for uplink. At this time, the TRP2 of 1101_2 receives the "modulated signal transmitted by the NR-UE1 of 1100_1, the modulated signal transmitted by the NR-UE2 of 1100_2, and the modulated signal transmitted by the NR-UE3 of 1100_3" of the first frequency (frequency band) 1201. Alternatively, it can be, for example Figure 48A As shown, TRP2 of 1101_2 performs communication using TDD or FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201, or may be Figure 48A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, TRP2 of 1101_2 does not communicate.

[0930] NR-UE1 of 1100_1 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE1 of 1100_1 is received by TRP2 of 1101_2, for example. In addition, NR-UE1 of 1100_1 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by TRP1 of 1101_1. In addition, it can be, for example, Figure 48A As shown, the NR-UE1 of 1100_1 performs communication using TDD and communication using FDD at a frequency (frequency band) other than the first frequency (frequency band) 1201. Figure 48A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE1 of 1100_1 does not communicate.

[0931] NR-UE2 of 1100_2 uses the first frequency (frequency band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (frequency band) 1201 transmitted by NR-UE2 of 1100_2 is received by TRP2 of 1101_2, for example. In addition, NR-UE2 of 1100_2 receives the modulation signal of the first frequency (frequency band) 1201 transmitted by TRP1 of 1101_1. In addition, it can be, for example, Figure 48A As shown, the NR-UE2 of 1100_2 performs communication using TDD and communication using FDD at a frequency (band) other than the first frequency (band) 1201. Figure 48A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE2 of 1100_2 does not communicate.

[0932] The NR-UE3 of 1100_3 uses the first frequency (band) 1201 for receiving modulation signals for downlink and for transmitting modulation signals for uplink. At this time, the modulation signal of the first frequency (band) 1201 transmitted by the NR-UE3 of 1100_3 is received by the TRP2 of 1101_2, for example. In addition, the NR-UE3 of 1100_3 receives the modulation signal of the first frequency (band) 1201 transmitted by the TRP1 of 1101_1. In addition, it can be, for example, Figure 48A As shown, the NR-UE3 of 1100_3 performs communication using TDD and communication using FDD at a frequency (band) other than the first frequency (band) 1201. Figure 48A Differently, at frequencies (frequency bands) other than the first frequency (frequency band) 1201, NR-UE3 of 1100_3 does not communicate.

[0933] exist Figure 48A , the frequency used for the "downlink" and the frequency used for the "uplink" are the same frequency (frequency band), but the present embodiment is not limited to this. The frequency used for the "downlink" and the frequency used for the "uplink" may also be partially the same frequency (frequency band). TDD and FDD have been described, so their explanation is omitted.

[0934] Figure 48B Shown Figure 47 This is an example of the transmission status of "TRP1 of 1101_1, TRP2 of 1101_2, NR-UE1 of 1100_1, NR-UE2 of 1100_2, NR-UE3 of 1100_3". Figure 48B , the horizontal axis is time.

[0935] like Figure 48B As shown, TRP1 of 1101_1 sets a downlink modulated signal transmission interval 4801 in the first time, and TRP2 of 1101_2 sets an uplink modulated signal reception interval 4802 in the first time.

[0936] NR-UE1 at 1100_1 sets uplink modulation signal transmission interval 4811_1 for the first time. Furthermore, TRP2 at 1101_2 sets uplink modulation signal transmission interval 4811_2 for the first time. Furthermore, TRP3 at 1101_3 sets uplink modulation signal transmission interval 4811_3 for the first time.

[0937] Alternatively, the downlink modulated signal transmission interval 4801 may be arranged at another time. Alternatively, the uplink modulated signal reception interval 4802 may be arranged at another time.

[0938] Furthermore, the uplink modulation signal transmission interval 4811_1 may be configured at other times, the uplink modulation signal transmission interval 4811_2 may be configured at other times, and the uplink modulation signal transmission interval 4811_3 may be configured at other times.

[0939] Figure 48C yes Figure 48B An example of the structure of each of the "downlink modulation signal transmission interval 4801", "uplink modulation signal transmission interval 4811_1", "uplink modulation signal transmission interval 4811_2", and "uplink modulation signal transmission interval 4811_3". In addition, Figure 48C , the horizontal axis is time.

[0940] In the downlink modulation signal transmission interval 4801 set by TRP1 of 1101_1, there are "modulation signal 4851_1 sent to NR-UE1 of 1100_1", "modulation signal 4851_2 sent to NR-UE2 of 1100_2", and "modulation signal 4851_3 sent to NR-UE3 of 1100_3".

[0941] Furthermore, in the uplink modulation signal transmission interval 4811_1 set by the NR-UE1 of 1100_1, there is a modulation signal 4861_1 sent to the TRP2 of 1101_2.

[0942] In the uplink modulation signal transmission interval 4811_2 set by NR-UE2 of 1100_2, there is a modulation signal 4861_2 sent to TRP2 of 1101_2.

[0943] In the uplink modulation signal transmission interval 4811_3 set by NR-UE3 of 1100_3, there is a modulation signal 4861_3 sent to TRP2 of 1101_2.

[0944] exist Figure 48C In the example, at time 1_1, there is "modulated signal 4851_1 sent by TRP1 of 1101_1 to NR-UE1 of 1100_1" and "modulated signal 4861_1 sent by NR-UE1 of 1100_1 to TRP2 of 1101_2." That is, NR-UE1 of 1100_1 is transmitting and receiving at time 1_1.

[0945] In addition, it is assumed that the time width of the "modulation signal 4851_1 of NR-UE1 sent to 1100_1" is equal to the time width of the "modulation signal 4861_1 of TRP2 sent to 1101_2".

[0946] By adopting the above-mentioned method, self-interference can sometimes be reduced, thereby achieving the effect of improving the frequency utilization efficiency of the system.

[0947] Furthermore, the start time of transmission of "modulated signal 4851_1 of NR-UE1 transmitted to 1100_1" coincides with the start time of transmission of "modulated signal 4861_1 of TRP2 transmitted to 1101_2." Consequently, for example, when reference signals (RS) are present in "modulated signal 4851_1 of NR-UE1 transmitted to 1100_1" and "modulated signal 4861_1 of TRP2 transmitted to 1101_2," the positional relationship between the reference signals included in "modulated signal 4851_1 of NR-UE1 transmitted to 1100_1" and "modulated signal 4861_1 of TRP2 transmitted to 1101_2" can be easily controlled, thereby potentially enabling each device to easily perform channel estimation, electric field strength estimation, frequency offset estimation, phase noise estimation, and other estimations. However, the start time of sending the "modulated signal 4851_1 of NR-UE1 sent to 1100_1" and the start time of sending the "modulated signal 4861_1 of TRP2 sent to 1101_2" do not necessarily have to be the same.

[0948] At time 1_2, there is a modulated signal 4851_2 sent by TRP1 of 1101_1 to NR-UE2 of 1100_2, and a modulated signal 4861_2 sent by NR-UE2 of 1100_2 to TRP2 of 1101_2. That is, NR-UE2 of 1100_2 performs both transmission and reception at time 1_2.

[0949] By adopting the above-mentioned method, self-interference can sometimes be reduced, thereby achieving the effect of improving the frequency utilization efficiency of the system.

[0950] In addition, the time width of the "modulated signal 4851_2 of NR-UE2 sent to 1100_2" and the time width of the "modulated signal 4861_2 of TRP2 sent to 1101_2" may be unequal.

[0951] Furthermore, the start time of transmission of "modulated signal 4851_2 for NR-UE2 of 1100_2" coincides with the start time of transmission of "modulated signal 4861_2 for TRP2 of 1101_2." Consequently, for example, when reference signals are included in "modulated signal 4851_2 for NR-UE2 of 1100_2" and "modulated signal 4861_2 for TRP2 of 1101_2," the positional relationship between the reference signals included in "modulated signal 4851_2 for NR-UE2 of 1100_2" and the reference signals included in "modulated signal 4861_2 for TRP2 of 1101_2" can be easily controlled. This can potentially result in the following effect: each device can easily perform channel estimation, electric field strength estimation, frequency offset estimation, phase noise estimation, and other estimations. However, the start time of sending the "modulated signal 4851_2 of NR-UE2 sent to 1100_2" and the start time of sending the "modulated signal 4861_2 of TRP2 sent to 1101_2" do not necessarily have to be the same.

[0952] At time 1_3, TRP1 at 1101_1 transmits modulated signal 4851_3 destined for NR-UE3 at 1100_3, and NR-UE3 at 1100_3 transmits modulated signal 4861_3 destined for TRP2 at 1101_2. That is, NR-UE3 at 1100_3 transmits and receives at time 1_3.

[0953] By adopting the above-mentioned method, self-interference can sometimes be reduced, thereby achieving the effect of improving the frequency utilization efficiency of the system.

[0954] In addition, the time width of the "modulated signal...
