For example, in the process of wireless communication, the downlink signal sent from the network side equipment such as the base station can be received by the amplifier, and the amplified signal can be forwarded to the terminal to enhance the strength of the downlink signal reaching the terminal; or the uplink signal from the terminal can be received by the amplifier, and the amplified signal can be forwarded to the network side equipment such as the base station to enhance the strength of the uplink signal reaching the base station.

[0003] However, when the amplifier amplifies and forwards uplink (UL) data or downlink (DL) data, it lacks effective time division duplex (TDD) configuration, which makes it unable to effectively distinguish UL amplification or DL ​​amplification, thereby resulting in low signal transmission efficiency.

[0030] Figure 1The following is a schematic diagram of the structure of a wireless communication system applicable to the embodiment of the present application. The wireless communication system includes a terminal 11 and a network side device 12. The terminal 11 may also be referred to as a terminal device or a user terminal (User Equipment, UE).

As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0031] The amplifier may be understood as a smart amplifier, a signal amplifier, etc. In this embodiment, the amplifier may include a mobile termination module (MT) and a radio unit (RU), wherein the MT is used to establish a connection with a network side device (such as a gNB, a donor node, a core network node, etc.), that is, the network side device interacts with the amplifier through the MT, so that the amplifier can accept control from the network side device, such as the network side device can control the transmission parameters of the amplifier, the on / off of the amplifier, the transmission beam, etc. The RU is used to establish a connection with the UE for signal interaction.

[0032] It should be noted that the amplifier can be understood as a network node, located between the UE and the network side device, to achieve amplification, forwarding and other processing of uplink / downlink signals.

[0033] The technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0034] like Figure 2 FIG. 2 is a flow chart of a signal transmission method 200 provided by an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by an amplifier, and may be specifically executed by hardware and / or software installed in the amplifier. In this embodiment, the method 200 may at least include the following steps.

[0035] S210: The amplifier determines a transmission behavior according to the first information.

[0036] The first information may be sent by a network side device (such as a donor node or a gNB, etc.) to indicate a TDD mode applicable to the amplifier, that is, UL, DL, or flexible, so that the amplifier determines its transmission behavior. It should be noted that the transmission behavior may also be understood as a transmission direction, such as a UL direction, a DL direction, or a flexible direction.

[0037] The first information may include at least TDD configuration information and / or data scheduling information.

[0038] In addition to indicating the TDD pattern applicable to the amplifier, the data scheduling information is also used to perform data scheduling on the terminal or the amplifier in this embodiment. Based on this, the process of the amplifier determining the transmission behavior according to the data scheduling information may include: when the data scheduled by the data scheduling information is UL data, the transmission behavior may be uplink transmission; or, when the data scheduled by the data scheduling information is DL data, the transmission behavior may be downlink transmission; or, when the data scheduling information does not perform data scheduling, the transmission behavior may be no transmission.

[0039] The TDD configuration information may be dedicated to the amplifier. In this embodiment, the TDD configuration information may be implemented by protocol agreement, network side configuration, or high-level configuration. For example, in this embodiment, the TDD configuration information may be determined by the network side device according to at least one of the following (101)-(102) and then sent to the amplifier.

[0040] (101) TDD configuration information of a terminal connected to the amplifier.

[0041] When the network-side device determines the TDD configuration information of the amplifier according to the TDD configuration information of the terminal connected to the amplifier, the determination process may include at least one of the following (1010)-(1112).

[0042] (1010) If the UE is configured as UL, determine that the amplifier is for UL transmission.

[0043] (1011) If the UE is configured for DL, determine that the amplifier is for DL ​​transmission.

[0044] (1012) If the UE is a flexible time unit, it is determined that the amplifier is in an OFF state, and the OFF state may be a state in which the RU part does not amplify and send the input signal, which may include at least one of a RU sleep state, a low output power state, a low amplification factor state, and a power-off state.

[0045] It should be noted that the aforementioned network side device determines the TDD configuration information of the amplifier based on the TDD configuration information of the terminal connected to the amplifier. It can also be understood that the network side device determines the SFI of the amplifier by monitoring the TDD configuration information carried by the time slot format indication (SFI) of the terminal.

[0046] (102) Data scheduling information of a terminal connected to the amplifier.

[0047] The data scheduling information may be a scheduling configured by Radio Resource Control (RRC) or a dynamic scheduling of Downlink Control Information (DCI). For example, the terminal may have a dynamically scheduled UL / DL transmission on a flexible symbol, and the network side device may monitor the dynamic scheduling information of the terminal to determine the TDD configuration information of the amplifier, such as UL transmission and DL transmission.

[0048] Based on this, when the network side device determines the TDD configuration information of the amplifier according to the data scheduling information of the terminal connected to the amplifier, its determination process may include at least one of the following (1020)-(1021).

[0049] (1020) If the data scheduling information schedules the UE for UL transmission, determining that the amplifier is for UL transmission.

[0050] (1021) If the data scheduling information schedules the UE for DL ​​transmission, determine that the amplifier is for DL ​​transmission.

[0051] S220: The amplifier performs signal transmission according to the transmission behavior.

[0052] As a possible implementation method, the way in which the amplifier transmits the signal according to the transmission behavior may include at least one of the following (201)-(203).

[0053] (201) When the transmission behavior is uplink transmission, the amplifier performs uplink transmission.

[0054] (202) When the transmission behavior is downlink transmission, the amplifier performs downlink transmission.

[0055] (203) When the transmission behavior is flexible transmission, the amplifier does not perform signal transmission.

[0056] It can be understood that in the aforementioned (201)-(203), the uplink transmission may include at least one of uplink reception, uplink amplification, and uplink forwarding; and / or the downlink transmission includes at least one of downlink reception, downlink amplification, and downlink forwarding.

[0057] In this embodiment, the amplifier determines the transmission behavior through TDD configuration information and / or data scheduling information, and then performs signal transmission based on the transmission behavior. Thus, it is possible to clearly know whether to perform UL amplification or DL ​​amplification, thereby matching the corresponding beam / power control method to achieve effective signal transmission and ensure wireless communication performance.

[0058] like Figure 3 FIG. 1 is a flow chart of a signal transmission method 300 provided by an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by an amplifier, and may be specifically executed by hardware and / or software installed in the amplifier. In this embodiment, the method 300 may at least include the following steps.

[0059] S310: The amplifier determines a transmission behavior according to first information.

[0060] The first information includes TDD configuration information and / or data scheduling information.

[0061] It can be understood that, in addition to referring to the relevant description in the aforementioned method embodiment 200, the implementation process of S310 can, as a possible implementation method, the first information can be transmitted through at least one of the following (301)-(307).

[0062] (301)F1 signaling.

[0063] That is, the first information is carried by the F1 signaling to indicate the TDD pattern (ie, TDD configuration information or data scheduling information) to the amplifier.

[0064] (302) System Information Block (SIB).

[0065] That is, the first information is carried by the SIB (such as SIB1) to indicate the TDD pattern to the amplifier.

[0066] (303) Master Information Block (MIB).

[0067] That is, the first information is carried by the MIB to indicate the TDD pattern to the amplifier.

[0068] (304) Physical downlink control channel (PDCCH).

[0069] That is, the first information is carried by the PDCCH to indicate the TDD pattern to the amplifier. Optionally, the PDCCH may be a group common PDCCH or a specific PDCCH.

[0070] In addition, as a possible implementation, the configuration information of the PDCCHH may be transmitted via SIB and / or MIB. Optionally, the configuration information of the PDCCH may include at least one of the following (3041)-(3042):

[0071] (3040) Detect the time domain resources of the PDCCH.

[0072] (3041) Detect the frequency domain resources of the PDCCH.

[0073] Among them, the aforementioned (3040)-(3041) can also be understood as: the amplifier monitors a certain channel control element (CCE) / resource element (RE), or the amplifier monitors certain time-frequency domain resources, etc., and there is no restriction on this.

[0074] (3042) The number of times the PDCCH is detected.

[0075] It can be understood that when the amplifier monitors the PDCCH, it can determine the time domain resources, frequency domain resources, etc. during monitoring based on the configuration information of the PDCCH.

[0076] Further, the second information corresponding to the PDCCH satisfies one of the following (a)-(b).

[0077] (a) The second information is specific to the amplifier.

[0078] The second information includes at least one of a search space (Search Space, SS), a radio network temporary identifier (Radio Network Temporary Identifier, RNTI), and a DCI format.

[0079] (b) The second information is commonly used for a plurality of amplifiers, and the plurality of amplifiers belong to the same cell.

[0080] The above (a) and (b) can be understood as follows: Figure 4 , an independent SS, RNTI, and DCI format can be configured through PUCCH. The independent SS, RNTI, and DCI format can be an MT dedicated SS, RNTI, and DCI format, or a group common SS, RNTI, and DCI format independently designed for multiple repeaters (i.e., RU groups) connected to the donor.

[0081] (305)RRC.

[0082] The RRC may include at least one of cell specific RRC signaling, UE dedicated signaling, MT dedicated signaling, and repeater dedicated signaling.

[0083] That is, the first information may be carried through the cell specific RRC signaling, UE dedicated signaling, MT dedicated signaling or repeater dedicated signaling to indicate the TDD pattern to the amplifier.

[0084] (306) Medium Access Control-Control Element (MACCE).

[0085] That is, the first information may be carried by the MAC CE to indicate the TDD pattern to the amplifier. As an implementation method, the MAC CE may be dynamically used to indicate the TDD pattern to the amplifier.

[0086] (307)SFI.

[0087] The first information may be carried by the SFI to indicate the TDD pattern to the amplifier. That is, the amplifier may monitor the SFI to determine the configuration information of its UL / DL / flexible symbol, such as the amplifier may determine the TDD configuration information within a certain period of time according to the indication in the monitored SFI.

[0088] In addition, in this embodiment, the SFI may include at least one of a cell specific SFI, a UE dedicated SFI, a MT dedicated SFI, and a repeater dedicated SFI. Taking the MT dedicated SFI as an example, the amplifier (such as the RU) may obtain the dynamic first information (including the TDD configuration information and / or the data scheduling information) only according to the MT dedicated SFI to change the flexible configuration of the semi-static configuration, or any one of the UL configuration / DL configuration / flexible configuration of the semi-static configuration.

[0089] Further, similar to the PDCCH, the second information corresponding to the SFI may also satisfy one of the following (a)-(b): wherein the second information includes at least one of a search space, an RNTI, and a DCI format.

[0090] (a) The second information is specific to the amplifier.

[0091] (b) The second information is commonly used for a plurality of amplifiers, and the plurality of amplifiers belong to the same cell.

[0092] The above (a) and (b) can be understood as follows: Figure 4 , an independent SS, RNTI, and DCI format can be configured through the MT dedicated SFI. The independent SS, RNTI, and DCI format can be an MT dedicated SS, RNTI, and DCI format, or a group common SS, RNTI, and DCI format independently designed for multiple repeaters (i.e., RU group) connected to the donor.

[0093] Further, based on the description of (301)-(307) above, if the amplifier successively receives multiple first information transmitted through different information (such as F1 signaling, SIB, MIB, PUCCH, SFI, etc.), then in order to ensure the validity of the TDD pattern in the amplifier, in this embodiment, the TDD pattern can also be partially or completely updated, which is explained below in combination with different update methods.

[0094] Method 1: Update the uplink time unit, downlink time unit, and flexible time unit in the second TDD pattern according to the first TDD pattern.

[0095] The first TDD pattern is determined according to the first information, and the second TDD pattern is determined according to the fourth information. Optionally, the second TDD pattern may be a TDD pattern that is in effect and dedicated to the amplifier, or a TDD pattern configured for a common terminal, and there is no limitation on this.

[0096] Based on this, in method 1, all configurations of the uplink time unit, downlink time unit, and flexible time unit need to be covered.

[0097] Mode 2: Update the flexible time unit in the second TDD pattern according to the first TDD pattern.

[0098] That is to say, only the configuration of the flexible time unit is updated (covered), and the configuration of the uplink time unit and the downlink time unit maintains the previous configuration.

[0099] Mode 3: Update the uplink time unit in the second TDD pattern according to the first TDD pattern.

[0100] That is to say, only the configuration of the uplink time unit is covered, and the configuration of the flexible time unit and the downlink time unit maintains the previous configuration.

[0101] Mode 4: Update the downlink time unit in the second TDD pattern according to the first TDD pattern.

[0102] That is to say, only the configuration of the downlink time unit is covered, and the configuration of the flexible time unit and the uplink time unit maintains the previous configuration.

[0103] Of course, for the relevant descriptions in Method 2 to Method 4, please refer to Method 1, and will not be repeated here.

[0104] In addition, the transmission method of the first information and the fourth information involved in the TDD pattern update process of mode 1 to mode 4 may include the following (401)-(405), the content is as follows.

[0105] (401) When the first information is transmitted via RRC signaling, the fourth information is transmitted via SIB or MIB.

[0106] (402) When the first information is transmitted via cell specific RRC signaling, the fourth information is transmitted via any one of SIB and MIB.

[0107] That is, the first TDD pattern carried in the cell-specific RRC signaling can override the second TDD pattern carried in the SIB or MIB, and the coverage method can refer to the aforementioned methods 1 to 4, such as overriding at least one of the configuration of the uplink time unit, the configuration of the downlink time unit, and the configuration of the flexible time unit in the second TDD pattern.

[0108] (403) In the case where the first information is transmitted through any one of UE dedicated RRC signaling, MT dedicated RRC signaling, and repeater dedicated RRC signaling, the fourth information is transmitted through any one of cell specific RRC signaling, SIB, and MIB.

[0109] That is, the first TDD pattern carried in UE dedicated RRC signaling, MT dedicated RRC signaling or repeater dedicated RRC signaling can cover the second TDD pattern carried in the cell specific RRC signaling.

[0110] Alternatively, the first TDD pattern carried in UE dedicated RRC signaling, MT dedicated RRC signaling or repeater dedicated RRC signaling may overwrite the second TDD pattern carried in the SIB.

[0111] Alternatively, the first TDD pattern carried in UE dedicated RRC signaling, MT dedicated RRC signaling or repeater dedicated RRC signaling may overwrite the second TDD pattern carried in the MIB.

[0112] In addition, its coverage method can refer to the aforementioned methods 1 to 4, such as covering at least one of the configuration of the uplink time unit, the configuration of the downlink time unit, and the configuration of the flexible time unit in the second TDD pattern.

[0113] (404) When the first information is transmitted via the first SFI, the fourth information is transmitted via RRC.

[0114] That is to say, the first TDD pattern carried in the first SFI can cover the second TDD pattern carried in the RRC, and the covering method can refer to the aforementioned methods 1 to 4, such as covering at least one of the configuration of the uplink time unit, the configuration of the downlink time unit, and the configuration of the flexible time unit in the second TDD pattern.

[0115] For example, when a base station or other network side device configures a TDD configuration for an amplifier through RRC, the base station or other network side device may send an SFI (ie, DCI format 2_0) to rewrite a flexible symbol in a high-level TDD configuration.

[0116] In addition, RRC may include at least one of cell specific RRC signaling, UE dedicated signaling, MT dedicated signaling, and repeater dedicated signaling.

[0117] (405) When the first information is transmitted via a first SFI, the fourth information is transmitted via a second SFI.

[0118] That is to say, the first TDD pattern carried in the first SFI can cover the second TDD pattern carried in the second SFI, and the covering method can refer to the aforementioned methods 1 to 4, such as covering at least one of the uplink time unit, downlink time unit, and flexible time unit in the second TDD pattern.

[0119] In one implementation, considering that there may be multiple types of SFI, in the case described in (405) where the first information is transmitted via the first SFI and the fourth information is transmitted via the second SFI information, the first SFI and the second SFI may include at least one of the following (4050)-(4053).

[0120] (4050) In the case where the first SFI is a UE dedicated SFI, the second SFI is a UEdedicated SFI.

[0121] That is, the first TDD pattern carried in the new UE dedicated SFI can cover the second TDD pattern carried in the UE dedicated SFI stored or received last time, and the covering method can refer to the aforementioned method 1-method 4, such as it can cover at least one of the configuration of the uplink time unit, the configuration of the downlink time unit, and the configuration of the flexible time unit in the second TDD pattern.

[0122] (4051) When the first SFI is an MT dedicated SFI or a repeater dedicated SFI, the second SFI is a UE dedicated SFI.

[0123] That is, the first TDD pattern carried in the MT dedicated SFI or repeater dedicated SFI can cover the second TDD pattern carried in the UE dedicated SFI stored or received last time, and the covering method can refer to the aforementioned methods 1 to 4, such as covering at least one of the configuration of the uplink time unit, the configuration of the downlink time unit, and the configuration of the flexible time unit in the second TDD pattern.

[0124] (4052) In the case where the first SFI is an MT dedicated SFI or a repeater dedicated SFI, the second SFI is an MT dedicated SFI or a repeater dedicated SFI.

[0125] That is, the first TDD pattern carried in the MT dedicated SFI or repeater dedicated SFI can cover the second TDD pattern carried in the MT dedicated SFI or repeater dedicated SFI stored or received last time, and the covering method can refer to the aforementioned methods 1 to 4, such as covering at least one of the configuration of the uplink time unit, the configuration of the downlink time unit, and the configuration of the flexible time unit in the second TDD pattern.

[0126] (4053) When the first SFI is a UE dedicated SFI, the second SFI is an MT dedicated SFI or a repeater dedicated SFI.

[0127] That is, the first TDD pattern carried in the UE dedicated SFI can cover the second TDD pattern carried in the MT dedicated SFI or repeater dedicated SFI stored or received last time, and the covering method can refer to the aforementioned methods 1 to 4, such as covering at least one of the configuration of the uplink time unit, the configuration of the downlink time unit, and the configuration of the flexible time unit in the second TDD pattern.

[0128] It can be understood that the aforementioned first SFI can be a new SFI, and the second SFI can be a previously stored or previously received SFI. That is, the first TDD pattern carried in the newly received valid SFI can overwrite the second TDD pattern carried in the previously stored or previously received SFI. Alternatively, the first TDD pattern carried in the newly received valid SFI can overwrite the configuration of the second TDD pattern part of the time unit in the time domain corresponding to the previously stored or previously received SFI.

[0129] In addition, if the new SFI (such as the first SFI) can indicate TDD configurations for multiple repeaters at the same time, such as UL / DL configurations, then DCI (indicating scheduling signaling) can only indicate UL / DL information for a specific repeater. It should be noted that the newSFI is to match the situation where the network side equipment dynamically schedules UL / DL in the UE's flexible symbol. The amplifier needs to know whether it is UL or DL ​​amplification at these positions to match the corresponding beam / power control and other parameters.

[0130] Further, based on the different transmission information given in the aforementioned (301)-(307), assuming that the first information is transmitted via third information, the type of the third information is related to whether the amplifier is in a connected state.

[0131] For example, when the amplifier is in a non-connected state, the third information may be at least one of SIB, MIB, and PDCCH. That is, when the amplifier is in a non-connected state, the first information may be transmitted through at least one of SIB, MIB, and PDCCH.

[0132] For another example, when the amplifier is in a connected state, the third information is at least one of F1 signaling, SIB, MIB, PDCCH, RRC, MAC CE, and SFI. That is, when the amplifier is in a connected state, the first information can be transmitted through at least one of F1 signaling, SIB, MIB, PDCCH, RRC, MAC CE, and SFI.

[0133] In addition, in this embodiment, there are multiple ways to determine the effective time of the third information for transmitting the first information. For example, the determination process is described below in combination with (501)-(503).

[0134] (501) The effective time of the third information is determined based on the first time unit and the first value of receiving the third information.

[0135] For example, assuming that the first value is L, and the amplifier receives the third information at time unit n, then the effective time of the first information indicated by the third information may be time unit n+L.

[0136] For another example, assuming that the first value is L, and the amplifier uses the first information indicated by the third information at time unit n, then the receiving time unit of the third information may be time unit nL.

[0137] Optionally, the first value is related to a subcarrier spacing (SCS), or the first value is implemented by a network side indication, a protocol agreement, or a high-level configuration, such as being indicated by the third information, etc., and is not limited here.

[0138] It can be understood that if the first value is related to SCS, the relationship between the first value and SCS can be predefined, for example, when SCS=15kHz, the first value is K1; when SCS=30kHz, the first value is K2; when SCS=60kHz, the first value is K3; when SCS=120kHz, the first value is K4. In this case, if it is necessary to determine the effective time of the third information, the first value can be determined based on the relationship between the predefined first value and SCS.

[0139] It should be noted that the time unit mentioned in this embodiment and subsequent embodiments may be a sub-slot, a time slot, a sub-frame, a frame, a symbol, a second, a millisecond, etc., and is not limited here.

[0140] (502) The effective time of the third information is determined according to the first indication information sent by the network side device.

[0141] For example, the first indication information may implicitly or explicitly indicate the effective time of the third information.

[0142] (503) The effective time of the third information is determined according to the receiving time of the next third information.

[0143] The effective time of the third information is from the effective start time of the third information to the receipt of the next valid third information.

[0144] For example, assuming that the third information is SFI, the effective time of the SFI may be from the time of receiving the SFI to the time of receiving the next valid SFI. That is, the amplifier may use the configuration information of the SFI to determine the transmission behavior until the next valid SFI is received. The valid SFI may be understood as DCI format 2-0 or a new SFI format.

[0145] For another example, assuming that the third information is F1-AP or RRC, then the effective time of the F1-AP or RRC may be from the time of receiving the F1-AP or RRC to the time of receiving the next valid F1-AP or RRC.

[0146] It should be noted that in the aforementioned (501)-(503), the effective time may include the effective start time, effective end time, effective duration, effective period, etc. of the third information, which is not limited here. In addition, the effective time of the third information can also be understood as the effective time of the first information.

[0147] Based on the description of the foregoing content, the updating of the foregoing configuration information and the determination of the effective time are explained below in combination with an example, as follows.

[0148] Example: Assume that a base station or other network-side device configures a TDD pattern for the amplifier through RRC. Then, the base station or other network-side device can send SFI (ie, DCI format 2_0) to rewrite (update) the flexible symbol in the high-level TDD configuration. In this case, the amplifier can monitor the SFI sent by the base station or other network-side device to determine its UL / DL / flexible symbol configuration. Among them, the amplifier can determine the TDD configuration within a period of time according to the indication in the SFI, such as the amplifier adopts the configuration of the SFI until the next valid SFI is received. The valid SFI is DCI format 2-0 or new SFI (ie, repeater specific / MT specific SFI).

[0149] S330: The amplifier performs signal transmission according to the transmission behavior.

[0150] It can be understood that the implementation process of S330 can refer to the relevant description in method embodiment 200, and will not be repeated here to avoid repetition.

[0151] In this embodiment, the transmission of the first information is achieved by configuring different signaling, thereby improving the flexibility and reliability of the transmission of the first information to further ensure the quality of wireless communication.

[0152] like Figure 5 FIG. 5 is a flow chart of a signal transmission method 500 provided by an exemplary embodiment of the present application. The method 500 may be, but is not limited to, executed by an amplifier, and may be specifically executed by hardware and / or software installed in the amplifier. In this embodiment, the method 500 may at least include the following steps.

[0153] S510: The amplifier determines a transmission behavior according to first information.

[0154] The first information includes TDD configuration information and / or data scheduling information.

[0155] It can be understood that, in addition to referring to the relevant description in the aforementioned method embodiment 200 or 300, as a possible implementation manner, the implementation process of S510 can also refer to Figure 5 The implementation process of S510 may further include S511, the content of which is as follows.

[0156] S511: The amplifier determines a transmission behavior within a target time unit according to the first information.

[0157] In one implementation, the amplifier determines the transmission behavior at the target time unit based on the first information, including any one of the following (601)-(606).

[0158] (601) When the first information determines that the target time unit is a flexible time unit, the transmission behavior of the amplifier in the target time unit is uplink transmission.

[0159] For example, if the resource configuration is a flexible symbol, the amplifier defaults the symbol to be a UL symbol, and receives, amplifies and forwards the uplink signal based on the UL symbol.

[0160] (602) When the first information determines that the target time unit is a flexible time unit, the transmission behavior of the amplifier in the target time unit is downlink transmission.

[0161] For example, if the resource configuration is a flexible symbol, the amplifier defaults to the symbol as a DL symbol and receives, amplifies and forwards the downlink signal based on the DL symbol.

[0162] (603) When the first information determines that the target time unit is a flexible time unit, the transmission behavior of the amplifier on the target time unit is no transmission.

[0163] For example, if the resource configuration is a flexible symbol, the amplifier does not receive, amplify, or forward uplink / downlink signals on the flexible symbol to avoid interference.

[0164] (604) When the first information determines that the target time unit is a flexible time unit and the first indication signaling is not received, the transmission behavior of the amplifier on the target time unit is no transmission.

[0165] For example, if the resource configuration is a flexible symbol, the amplifier does not receive, amplify, or forward uplink / downlink signals on the flexible symbol if it does not receive an uplink / downlink direction indication or a base station scheduling indication (ie, the first indication signaling) for the flexible symbol to avoid interference.

[0166] The location indicates whether the signaling is used by the base station to instruct the flexible symbol of the intelligent amplifier to UL amplification or DL ​​amplification.

[0167] (605) When the first information determines that the target time unit is a flexible time unit and a second indication signaling is received, but the second indication signaling indicates that the target time unit is a flexible time unit, the transmission behavior of the amplifier on the target time unit is no transmission.

[0168] For example, if the resource configuration is a flexible symbol, when the amplifier receives an uplink / downlink direction indication or a base station scheduling indication (i.e., a second indication signaling) for the flexible symbol, if the uplink / downlink direction indication or the base station scheduling indication indicates that the flexible symbol is a flexible time unit, then the amplifier does not receive, amplify, or forward the uplink / downlink signal on the flexible symbol to avoid interference.

[0169] (606) When the first information determines that the target time unit is a flexible time unit, a second indication signaling is received, and the second indication signaling indicates that the target time unit is neither uplink nor downlink, the transmission behavior of the amplifier on the target time unit is no transmission.

[0170] The implementation process of (606) may refer to the aforementioned terminal description of (605), and will not be described again to avoid repetition.

[0171] Further, in this embodiment, if the amplifier does not receive the first information, at least one of the following (701)-(702) may be executed.

[0172] (701) Send a TDD pattern request to the network side device.

[0173] The TDD pattern request is used to request first information, such as dedicated TDD configuration information or data scheduling information, from the network side device.

[0174] (702) Determine the transmission behavior according to specified TDD configuration information, where the specified TDD configuration information is TDD configuration information configured by the network side device for the terminal.

[0175] That is, the amplifier may directly use the TDD configuration information received in SIB1, cell specific RRC and configured for common UE, and determine the transmission behavior according to the TDD configuration information.

[0176] It should be noted that after the transmission behavior is determined according to the specified TDD configuration, when the amplifier receives the first information sent by the network side device, the amplifier stops executing the step of determining the transmission behavior according to the specified TDD configuration, and executes the step of determining the transmission behavior according to the first information. That is, when the amplifier receives the dedicated TDD configuration information sent by the network side device, it abandons the use of the TDD configuration information received in SIB1 for the ordinary UE configuration, and uses the newly received dedicated TDD configuration information to determine the transmission behavior.

[0177] Furthermore, in one implementation, assuming that the first information is transmitted via SFI, when the amplifier receives SFI configurations from multiple network-side devices (such as donor nodes), considering that the amplifier requires that at most one SFI among multiple SFIs corresponding to the same slot / symbol indicates DL / UL, and the other SFI indications are flexible; or in other words, the amplifier can only provide service to one network-side device at a time, in this case, if the amplifier receives SFI (i.e., the first information) sent from multiple network-side devices, then the amplifier satisfies at least one of the following (801)-(804).

[0178] (801) The configuration information of multiple first information is not supported or rejected.

[0179] Among them, "not support" and "refuse" in this embodiment can also be understood as prohibition, suspension, release, etc., which are not limited here.

[0180] (802) The plurality of first information indicating that the target time unit is uplink transmission and downlink transmission is not supported or rejected.

[0181] (803) Supporting multiple first information indications, the target time unit is an uplink time unit or a downlink time unit or a flexible time unit.

[0182] (804) Determine first information for determining the transmission behavior from at least two pieces of the first information according to a preset rule.

[0183] The preset rule may be implemented by protocol agreement, high-level configuration or network-side device configuration, which is not limited here. As a possible implementation, the aforementioned determination of the first information used for determining the transmission behavior from at least two of the first information according to the preset rule may include at least one of the following (9041)-(9042).

[0184] (9041) Determine, based on the identification information of each of the network side devices, first information used for determining the transmission behavior from at least two of the first information.

[0185] (9042) Determine, based on the priority information of each of the network side devices, first information for determining the transmission behavior from at least two of the first information.

[0186] Based on this, the amplifier performs uplink transmission or downlink transmission according to target transmission configuration indicator (TCI) information; wherein the target TCI information is TCI information of the network side device that sends the determined first information.

[0187] S520: The amplifier performs signal transmission according to the transmission behavior.

[0188] It can be understood that the implementation process of S330 can refer to the relevant description in method embodiment 200, and will not be repeated here to avoid repetition.

[0189] In this embodiment, a method for determining transmission behaviors in different scenarios is further provided, which can further ensure the quality of wireless communication.

[0190] like Figure 6 , which is a flow chart of a signal transmission method 600 provided by an exemplary embodiment of the present application, the method 600 may be, but is not limited to, executed by a network side device, and specifically may be executed by hardware and / or software installed in the network side device. In this embodiment, the method 600 may at least include the following steps.

[0192] The first information includes time division duplex (TDD) configuration information and / or data scheduling information.

[0195] As a possible implementation manner, the RRC includes at least one of cell specific RRC signaling, UE dedicated signaling, MT dedicated signaling, and amplifier repeater dedicated signaling.

[0196] As a possible implementation method, the second information corresponding to the PDCCH or the SFI satisfies one of the following: the second information is dedicated to the amplifier; the second information is shared by multiple amplifiers; wherein the second information includes at least one of the search space, RNTI, and DCI format.

[0201] As a possible implementation manner, before the network side device sends the first information to the amplifier, the method further includes: the network side device receiving a TDD pattern request sent by the amplifier.

[0202] In this embodiment, the network side device sends TDD configuration information and / or data scheduling information to the amplifier, so that the amplifier can determine the transmission behavior based on the TDD configuration information and / or data scheduling information, and then perform signal transmission based on the transmission behavior. As a result, the amplifier can clearly know whether to perform UL amplification or DL ​​amplification, thereby matching the corresponding beam / power control method to achieve effective signal transmission and ensure wireless communication performance.
