[0035] Figure 1This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal 11 and a network-side device 12. Terminal 11 can be a mobile phone, tablet computer, laptop computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR) / virtual reality (VR) device, robot, wearable device, vehicle-mounted device (VUE), pedestrian terminal (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. It should be noted that the specific type of terminal 11 is not limited in this embodiment. Network-side equipment 12 may include access network equipment or core network equipment. Access network equipment 12 may also be referred to as radio access network equipment, radio access network (RAN), radio access network function, or radio access network unit.

The base station is not limited to specific technical terms. It should be noted that in this application embodiment, only a base station in an NR system is used as an example for description, and the specific type of base station is not limited.

[0036] To facilitate understanding of the embodiments of this application, the following will be described first.

[0037] In this application embodiment, the amplifier may also be referred to as one of the following: signal amplifier, repeater, repeater, intelligent repeater, network controlled repeater (NCR), etc., without limitation. The amplifier can be used to extend the coverage of a cell, or to supplement coverage blind spots, including receiving and amplifying downlink signals from the upstream base station (host) to increase the signal strength reaching the terminal; and amplifying uplink signals from the terminal to increase the strength of the uplink signal from the terminal to the upstream base station.

[0038] The amplifier can receive control from the upstream base station (parent node) or the host base station (donor). That is, the base station can control the amplifier's transmission parameters, such as switching the amplifier on and off and / or the transmission beam, to improve the amplifier's efficiency and reduce interference. Figure 2 The network structure shown contains three network nodes. The middle network node is an amplifier, which includes a Mobile Termination (MT) module and a Radio Unit (RU) module. The RU can also be represented as an RF module (Radio Frequency Unit) or an amplifier module (repeater unit). It is possible that the amplifier only contains one of the MT and RU modules. The MT can establish a connection with the upstream base station (such as a gNB). The base station interacts with the amplifier through the MT, exchanging control signaling and instructing the amplifier's MT / RU on transmit / receive parameters.

[0039] for Figure 2 The network structure shown has downlink (DL) transmission and uplink (UL) transmission between the gNB and MT. For UL signal transmission, the involved link is MT TX / MT UL, i.e., gNB RX; for DL ​​signal transmission, the involved link is MT RX / MT DL, i.e., gNB TX. Here, TX represents transmission and RX represents reception. The gNB also has DL and UL transmissions with the UE. If the gNB sends a DL signal, it is amplified and forwarded to the UE, then the link between the gNB and RU is RU DL RX, i.e., gNB DL TX, and the link between the RU and UE is RU DL TX, i.e., UE DL RX, as shown in 3A. If the UE sends a UL signal, it is amplified and forwarded to the gNB, then the link between the UE and RU is RU UL RX, i.e., UE UL TX, and the link between the RU and gNB is RU UL TX, i.e., gNB UL RX, as shown in 3B. There is approximately a 5μs delay between the received signal and the forwarded signal at the RU.

[0040] There are multiple link states on the amplifier, such as MT TX / MT UL, MT RX / MT DL, RU UL RX, RU ULTX, RU DL RX, RU DL TX, etc.

[0041] Alternatively, the intelligent repeater can be replaced with a RIS (Intelligent Reflector Panel) or a remote radio unit (RRU) for the base station. The MT section can also be a repeater controller.

[0042] Classic signal amplifiers operate continuously after power-on without switching on / off to save power. When there is no signal to relay, they amplify interference and noise signals from other cells, interfering with reception in their own cell. They also transmit side lobes and noise signals from their own transmitted signal to other cells, further interfering with reception and exacerbating system interference. Therefore, the ON / OFF mode of the repeater needs to be considered to reduce interference caused by noise amplification. Furthermore, disabling repeater relay when it is not needed reduces power consumption, thus achieving energy savings.

[0043] It should be noted that the ON state of the amplifier mentioned in this article refers to the state in which the RU section normally amplifies and transmits the input signal. The OFF state of the amplifier mentioned in this article refers to the state in which the RU section does not amplify and transmit the input signal, and can be one of the following states: RU sleep state, low output power state, low amplification factor state, or power-off state.

[0044] Because amplifiers have multiple link states, such as MT TX / MT UL, RU UL RX, RU UL TX, etc., maintaining multiple UL timings increases signal processing complexity. Maintaining only one UL timing, but with transmitted UL signals not aligned with time slot boundaries or symbol boundaries, can cause inter-symbol interference, leading to poor UL signal performance and low demodulation success rate. Therefore, amplifier UL timing needs to be considered. The same logic applies to DL. Furthermore, the transition between receiving and transmitting signals from the amplifier may require processing time, which also impacts timing considerations. Therefore, timing adjustments on the amplifier need to be considered to ensure good signal transmission and reception between the base station, amplifier, and terminal, reducing inter-slot / symbol interference.

[0045] Optionally, in this application, RU UL refers to the uplink forwarding state of the RU (such as including RU UL RX and RU UL TX link states), and RU DL refers to the downlink forwarding state of the RU (such as including RU DL RX and RU DL TX link states).

[0046] The timing adjustment method, configuration method, device, amplifier, and base station provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0047] Please see Figure 4 , Figure 4 This is a flowchart of a timing adjustment method provided in an embodiment of this application. The method is applied to an amplifier, which may be an NCR amplifier, etc. Figure 4 As shown, the method includes the following steps:

[0048] Step 41: The amplifier determines the timing of the amplifier's MT and / or RU based on at least one of the following: a predefined mode, a preconfigured mode, or the first information acquired.

[0049] Optionally, the first information mentioned above may include, but is not limited to, at least one of the following:

[0050] Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE), Downlink Control Information (DCI), Downlink data, Service Request (SR), Physical Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), Uplink data, etc.

[0051] Optionally, the first information mentioned above may include timing mode information, so that the amplifier determines the timing of the amplifier's MT and / or RU using a corresponding timing mode based on the timing mode information.

[0052] In some embodiments, the timing of the amplifier's MT and / or RU can be determined according to a predefined or pre-configured method. That is, the timing of the amplifier's MT and / or RU can be determined directly using a certain method without receiving data / signaling.

[0053] In other embodiments, after acquiring the first information, the amplifier can determine the timing of its MT and / or RU based on the acquired first information. The first information can be downlink signaling / data from the base station (such as RRC signaling, MAC CE, DCI, etc.), which can instruct the amplifier to perform timing adjustments and / or indicate the method of timing adjustment. The first information can also be uplink signaling / data from the terminal (such as SR, PRACH, uplink data, etc.), which can instruct the amplifier to perform timing adjustments and / or indicate the method of timing adjustment. However, it should be noted that the uplink and downlink signaling may not indicate timing adjustment-related content; that is, after acquiring the signaling / data from the base station and / or the terminal, the amplifier can determine the timing of its MT and / or RU using a certain method. The first information may include timing method information to determine the timing method of the NCR.

[0054] In other embodiments, the amplifier can determine the timing of its MT and / or RU based on a predefined method and the acquired first information. That is, after acquiring signaling / data from the base station and / or terminal, the amplifier can determine the timing of its MT and / or RU using a certain method.

[0055] The timing adjustment method in this application embodiment determines the timing of the MT and / or RU of the amplifier based on a predefined method and / or a preconfigured method and / or acquired first information. This ensures the amplifier's timing is accurate, guaranteeing uplink and downlink timing alignment and reducing interference between time slots / symbols.

[0056] In the embodiments of this application, the timing of the amplifier's MT and / or RU may include downlink timing (DL timing) and / or uplink timing (UL timing), which are described below.

[0057] (1) The DL timing of MT and / or RU satisfies at least one of the following:

[0058] 1) The receive timing and / or downlink timing of MT are determined based on the downlink timing of the base station; that is, MT RX timing / MTDL timing is determined based on the DL timing of gNB.

[0059] 2) The downlink receive timing of the RU is aligned with the receive timing and / or downlink timing of the MT; that is, the RU DL RX timing is aligned with the MT RX timing / MT DL timing; or, the downlink receive timing of the RU, RU DL RX timing, is determined according to the DL timing of the gNB.

[0060] 3) The downlink transmission timing of the RU is determined based on the downlink reception timing of the RU; that is, the RU DL TX timing is determined based on the RU DL RX timing. Alternatively, the RU DL TX timing is determined based on the MT RX timing / MT DL timing; or, the RU DL RX timing is determined based on the DL timing of the gNB.

[0061] Optionally, in this case 3), the downlink transmission timing of the RU is delayed by a first time compared to the downlink reception timing of the RU. That is, RUDL TX is transmitted after RU DL RX delayed by a first time. The first time can be set based on actual needs, such as x1μs, and is not limited thereto.

[0062] (2) The UL timing of MT and / or RU can be in two cases:

[0063] Case 1: The UL timing of MT and / or RU must meet at least one of the following:

[0064] 4) The transmission timing and / or uplink timing of MT are determined according to the time advanced (TA) signaling of MT; that is, MT TX timing / MT UL timing is determined according to MT TA signaling.

[0065] 5) The uplink transmission timing of RU is aligned with the uplink timing of MT; that is, RU UL TX timing is aligned with MT UL timing; or, RU UL TX timing is determined according to MT TA signaling.

[0066] 6) The uplink receive timing of the RU is determined based on the uplink transmit timing of the RU; that is, the RU UL RX timing is determined based on the RU UL TX timing; or the RU UL RX timing is determined based on the MT UL timing; or the RU UL RX timing is determined based on the MT TA signaling.

[0067] Optionally, under this 6), the uplink receive timing of the RU is advanced by a second time compared to the uplink transmit timing of the RU, that is, RUUL RX is received with a timing two times earlier than RU UL TX. The second time can be set based on actual needs, such as x2μs, and is not limited thereto.

[0068] Case 2: The UL timing of MT and / or RU must meet at least one of the following:

[0069] 7) The uplink reception timing of the RU is determined according to the second information, which includes at least one of the following: the uplink timing of the terminal, the transmission timing of the terminal, and the transmission timing of the next-hop node of the RU; that is, the RU UL RX timing is determined according to the UE UL / UE TX / TX timing of the next-hop node.

[0070] 8) The uplink transmission timing of the RU is determined based on the uplink reception timing of the RU; that is, the RU UL TX timing is determined based on the RU UL RX timing; or, the RU UL TX timing is determined based on the uplink timing of the terminal, the transmission timing of the terminal, and / or the transmission timing of the next-hop node of the RU.

[0071] Optionally, in this 8), the uplink transmission timing of the RU is delayed by a second time compared to the uplink reception timing of the RU, that is, RUUL TX is transmitted after a second time delay from RU UL RX. The second time can be set based on actual needs, such as x2μs, and is not limited thereto.

[0072] 9) The uplink transmission timing of the RU is aligned with the uplink timing and / or transmission timing of the MT; or, the amplifier does not expect the uplink transmission timing of the RU to be misaligned with the uplink timing and / or transmission timing of the MT; that is, the RU UL TX timing is aligned with MT UL timing / MT TX timing; or, the repeater does not expect the RU UL TX timing to be misaligned with MT UL timing / MT TX timing. The alignment of the UL timing is guaranteed by the network through control of the UE TA. Alternatively, the RU UL TX timing is determined based on the RU UL RX timing; or, the RU UL TX timing is determined based on the uplink timing of the terminal, the transmission timing of the terminal, and / or the transmission timing of the next-hop node of the RU.

[0073] It should be noted that the first and second times mentioned above may be the same or different. Although the alignment order of cases 1 and 2 is different, the timing results obtained are the same.

[0074] Optionally, the first time and / or the second time mentioned above satisfy at least one of the following:

[0075] a) The first and / or second time is one of the following: a predefined value, a preconfigured value, or a network configuration value.

[0076] For example, the first time and the second time are both equal to 5μs or 10μs; or, the first time is equal to 5μs and the second time is equal to 10μs; or, the first time is equal to 10μs and the second time is equal to 5μs.

[0077] b) The first and / or second times are related to the sub-carrier space (SCS) or frequency range (FR).

[0078] Optionally, when the first time and / or the second time are related to SCS, the first time and / or the second time are equal to X / 2. u Alternatively, the first time and / or the second time are equal to X / u; where X is one of the following: a predefined value, a preconfigured value, or a network configuration value; and u is a parameter corresponding to the SCS.

[0079] For example, if SCS = 15kHz, then u = 0; if SCS = 30kHz, then u = 1; if SCS = 60kHz, then u = 2; if SCS = 120kHz, then u = 3; if SCS = 240kHz, then u = 4; if SCS = 480kHz, then u = 5; if SCS = 960kHz, then u = 6.

[0080] c) The first and / or second times are implementation-based values.

[0081] For example, the protocol can specify that the first and / or second times are greater than or equal to the processing time for the amplifier to receive and forward signals. Alternatively, the values ​​of the first and / or second times can be no less than X1, or greater than X1, where X1 is a predefined / preconfigured processing time for the amplifier to receive and forward signals. Optionally, X1 is related to the SCS, and the mapping relationship between the value of X1 and the SCS can be predefined / preconfigured.

[0086] Optionally, to better ensure timing adjustments, the amplifier can report the first time and / or the second time, and / or report the reference SCS and / or frequency range, so that the base station can know the corresponding switching time.

[0087] In this embodiment, the amplifier's ON state can be controlled to reduce interference. The terminal can determine the amplifier's turn-on time based on third information. The amplifier's turn-on time can be understood as the starting position of the amplifier's available resources or the starting position of transmission. The third information may include at least one of the following: the uplink transmission timing of the RU, the uplink timing of the MT, and the start time of the RU's time unit. This time unit may include, but is not limited to, a time slot, a symbol, a subframe, or a preset pattern.

[0088] Optionally, when the amplifier's turn-on time is determined based on the uplink transmission timing of the RU, the uplink start time of the RU is advanced by a fourth time compared to the uplink transmission timing of the RU. And / or, when the amplifier's turn-on time is determined based on the uplink timing of the MT, the uplink start time of the RU is advanced by a fifth time compared to the uplink timing of the MT. That is, the RU UL is turned on / ON at least a preset time before the RU UL TX / MTUL is enabled.

[0089] Optionally, when determining the amplifier's turn-on time based on the RU's transmission start time, the amplifier's turn-on time is six hours earlier than the start time of the RU's time unit. For example, the amplifier is turned on / ON a preset time before the start position of the RU slot / symbol.

[0090] It should be noted that the fourth, fifth, and sixth times mentioned above can be set based on actual needs, and can be the same or different; there are no restrictions on this.

[0091] Optionally, the fourth, fifth, and sixth times mentioned above can satisfy at least one of the following:

[0092] a) At least one of the fourth, fifth, and sixth times is one of the following: a predefined value, a preconfigured value, or a network configuration value.

[0093] For example, the fourth, fifth, and sixth times are all equal to 5μs or 10μs.

[0094] b) At least one of the fourth, fifth, and sixth times is related to the SCS or frequency range.

[0095] Optionally, when at least one of the fourth, fifth, and sixth times is related to SCS, the fourth, fifth, and sixth times are equal to X / 2. u Alternatively, at least one of the fourth, fifth, and sixth times is equal to X / u; wherein X is one of the following: a predefined value, a preconfigured value, or a network configuration value; and u is a parameter corresponding to the SCS.

[0096] For example, if SCS = 15kHz, then u = 0; if SCS = 30kHz, then u = 1; if SCS = 60kHz, then u = 2; if SCS = 120kHz, then u = 3; if SCS = 240kHz, then u = 4; if SCS = 480kHz, then u = 5; if SCS = 960kHz, then u = 6.

[0097] c) At least one of the fourth, fifth, and sixth times is an implementation-based value.

[0098] For example, the protocol can require that at least one of the fourth, fifth, and sixth times is greater than or equal to the processing time for the amplifier to receive and forward signals. Alternatively, at least one of the fourth, fifth, and sixth times can be no less than X1, where X1 is a predefined / preconfigured processing time for the amplifier to receive and forward signals. Optionally, X1 is related to the SCS, and the mapping relationship between the value of X1 and the SCS can be predefined / preconfigured.

[0099] d) At least one of the fourth, fifth, and sixth times is not less than the seventh time, or is greater than the seventh time.

[0100] Optionally, the seventh time can satisfy at least one of the following:

[0101] The seventh time is the signal transmission and reception conversion time of the predefined or preconfigured amplifier;

[0102] The seventh time is related to SCS. For example, the mapping relationship between the value of the third time and SCS can be predefined / preconfigured.

[0103] e) The fourth, fifth, and sixth times may be the same or different.

[0104] Please see Figure 5 , Figure 5 This is a flowchart of a configuration method provided in an embodiment of this application. This method is applied to a base station, such as... Figure 5 As shown, the method includes the following steps:

[0105] Step 51: The base station sends fourth information to the amplifier, which is used to configure or indicate the signal transmission and reception switching time of the amplifier.

[0106] This allows the amplifier to determine the timing of its MT and / or RU based on the signal transmission and reception switching time of the amplifier, thereby ensuring uplink and downlink timing alignment and reducing interference between time slots / symbols.

[0107] For example, the signal transmission and reception conversion time of the amplifier configured or indicated above is equal to the first time or the second time in the above embodiment, that is, the conversion time of RU DL RX->RU DL TX and / or the conversion time of RU UL RX->RU UL TX. These two conversion times may be the same or different.

[0108] Optionally, the signal transmission / reception switching time of the amplifier satisfies at least one of the following:

[0109] The signal transceiver switching time of the amplifier is related to the SCS or frequency range;

[0110] The signal transceiver conversion time of the amplifier is based on the implemented value;

[0111] The signal transmission and reception conversion time of the amplifier is not less than the eighth time, or greater than the eighth time.

[0112] Optionally, when the signal transceiver switching time of the amplifier is related to the SCS, the signal transceiver switching time of the amplifier is equal to X / 2. u Alternatively, the signal transmission / reception conversion time of the amplifier is equal to X / u; where X is one of the following: a predefined value, a pre-configured value, or a network configuration value; and u is the parameter corresponding to the SCS.

[0113] For example, if SCS = 15kHz, then u = 0; if SCS = 30kHz, then u = 1; if SCS = 60kHz, then u = 2; if SCS = 120kHz, then u = 3; if SCS = 240kHz, then u = 4; if SCS = 480kHz, then u = 5; if SCS = 960kHz, then u = 6.

[0114] Optionally, the eighth time satisfies at least one of the following:

[0115] The eighth time is the signal transmission and reception conversion time of a predefined or preconfigured amplifier;

[0116] The eighth time is related to SCS.

[0117] Optionally, the signal transceiver switching time of the amplifier includes at least one of the following:

[0118] The signal transceiver conversion time of the amplifier's MT;

[0119] The signal transmission and reception switching time of the amplifier's RU.

[0120] Optionally, the base station can receive the reference SCS and / or frequency range reported by the amplifier to ensure timing adjustments.

[0121] The following examples illustrate this application.

[0122] Example 1:

[0123] In this example 1, as Figure 6 As shown, MT / RU DL timing can include:

[0124] 1) The gNB sends DL data, and the repeater determines the MT DL / MT RX timing based on the received DL data;

[0125] 2) RU DL RX timing is aligned with MT DL timing; or, in other words, RU DL TX timing is determined based on the DL data sent by the gNB.

[0126] 3) RU DL TX is sent xμs after RU DL RX; where x is a predefined value or a value determined according to the gNB configuration;

[0127] MT / RU UL timing may include:

[0128] 1) gNB sends MT TA information, and repeater MT determines the timing of MT UL based on MT DL and MT TX;

[0129] 2) The gNB sends UE TA information, and the UE determines UE ULRX, i.e., RU ULTX timing, based on UE DL and UE TA information;

[0130] 3) Repeater RU determines the timing of RU UL RX based on UE UL;

[0131] 4) repeater RU UL TX is sent xμs after a timeout of RU UL TX. The repeater does not expect RU ULTX to be misaligned with MT UL;

[0132] It should be pointed out that, Figure 6 The transmission delay Tdelta shown can be 0 or non-zero.

[0133] Example 2:

[0134] In this example 2, as Figure 7As shown, the repeater opens at the start of the RU transmission, or at an optional start point such as the slot / symbol boundary, xμs earlier than the MT UL. For example, x equals 5μs or 10μs, where x is related to the SCS. By opening xμs earlier, it ensures that the RU UL TX is forwarded at the slot / symbol boundary, and the gNB can receive the entire slot / symbol's data. Otherwise, if the repeater does not open in advance, i.e., at the slot boundary, the first xμs of the RU UL TX transmission will be in a non-amplified forwarding state, and the data from those first xμs cannot be forwarded to the gNB, resulting in data loss. Considering the xμs RU RX->TX conversion time, the RU ON time needs to be xμs earlier at the slot / symbol boundary to ensure the integrity of the data forwarded by the RU UL to the gNB.
