This method 200 Repeater may be executed by, but not limited to, specifically Repeater may also be executed by the hardware and / or software installed in the

[0027] S210, Repeater determines the transmission behavior based on the first information.

[0028] Here, the first information is transmitted by a network-side device (such as a Donor node or a gNB, etc.) to the Repeater TDD mode (pattern) applied to, that is, to indicate UL, DL, flexible, and further to determine its transmission behavior for the Repeater It may be.

[0067] As can be understood, the Repeater may determine the time-domain resource, frequency-domain resource, etc. during monitoring based on the configuration information of the PDCCH when performing PDCCH monitoring.

[0068] Furthermore, the second information corresponding to the PDCCH satisfies one of the following (a)-(b).

[0069] (a) The second information is dedicated to the Repeater .

[0070] Here, the second information includes at least one of a search space (SS), a radio network temporary identifier (RNTI), and a DCI format.

This independent SS, RNTI, and DCI format may be the MT dedicated SS, RNTI, and DCI format, or may be the group common SS, RNTI, and DCI format independently designed for a plurality of repeaters (i.e., RU group) connected to the donor. It may be understood that this is also possible.

Taking the MT dedicated SFI as an example, the above-mentioned Repeater (e.g., RU) may obtain dynamic first information (including TDD configuration information and / or data scheduling information) based only on the MT dedicated SFI, and change any one of the semi-statically configured flexible configuration, or the semi-statically configured UL configuration / DL configuration / flexible configuration.

It may be understood that this is also possible.

[0085] Furthermore, based on the descriptions of the above (301)-(307), when the plurality of first information transmitted by different information (such as F1 signaling, SIB, MIB, PUCCH, SFI, etc.) is received before and after, in order to ensure the effectiveness of the TDD pattern in the Repeater in this embodiment, part or all of the updates of the TDD pattern may be performed.

[0086] Method 1: Update the uplink time unit, downlink time unit, and flexible time unit in the second TDD pattern based on the first TDD pattern.

[0087] Here, the first TDD pattern is determined based on the first information, and the second TDD pattern is determined based on the fourth information. Optionally, the second TDD pattern may be the TDD pattern that is being activated and dedicated to the Repeater or may be the TDD pattern configured for ordinary terminals, and there is no limitation in this regard.

[0088] Based on this, in Method 1, it is necessary to override all configurations of the uplink time unit, downlink time unit, and flexible time unit.

[0089] Method 2: Update the flexible time unit in the second TDD pattern based on the first TDD pattern.

[0090] That is, only the configuration of the flexible time unit is updated (overridden), and the configurations of the uplink time unit and downlink time unit maintain the previous configurations.

[0091] Method 3: Update the uplink time unit in the second TDD pattern based on the first TDD pattern.

[0092] That is, only the configuration of the uplink time unit is overridden, and the configurations of the flexible time unit and downlink time unit maintain the previous configurations.

[0093] Method 4: Update the downlink time unit in the second TDD pattern based on the first TDD pattern.

[0094] That is, only the configuration of the downlink time unit is overridden, and the configurations of the flexible time unit and uplink time unit maintain the previous configurations.

[0095] Of course, for the related descriptions in Methods 2 - 4, Method 1 can be referred to and will not be further elaborated here.

[0096] Also, the transmission method of the first information and the fourth information related to the TDD pattern update process of Methods 1 - 4 may include the descriptions in the following (401) - (405), and the content is as follows.

[0097] (401) When the first information is transmitted by RRC signaling, the fourth information is transmitted by SIB or MIB.

[0098] (402) When the first information is transmitted by cell specific RRC signaling, the fourth information is transmitted by either the SIB or the MIB.

[0099] That is, the first TDD pattern carried by cell specific RRC signaling may override the second TDD pattern carried by the SIB or the MIB. The overriding method can refer to the aforementioned methods 1 - 4. For example, at least one of the configurations of the uplink time unit, the downlink time unit, and the flexible time unit in the second TDD pattern may be overridden.

[0100] (403) When the first information is transmitted by any one of UE dedicated RRC signaling, MT dedicated RRC signaling, and repeater dedicated RRC signaling, the fourth information is transmitted by any one of cell specific RRC signaling, the SIB, and the MIB.

[0101] That is, the first TDD pattern carried by UE dedicated RRC signaling, MT dedicated RRC signaling, or repeater dedicated RRC signaling may override the second TDD pattern carried by cell specific RRC signaling.

[0102] Alternatively, the first TDD pattern carried by UE dedicated RRC signaling, MT dedicated RRC signaling, or repeater dedicated RRC signaling may override the second TDD pattern carried by the SIB.

[0103] Alternatively, the first TDD pattern carried in UE dedicated RRC signaling, MT dedicated RRC signaling, or repeater dedicated RRC signaling may override the second TDD pattern carried in the MIB.

[0104] Also, the overriding method can refer to the aforementioned methods 1 - 4. For example, at least one of the configurations of the uplink time unit, downlink time unit, and flexible time unit in the second TDD pattern may be overridden.

[0105] (404) When the first information is transmitted by the first SFI, the fourth information is transmitted by RRC.

[0106] That is, the first TDD pattern carried in the first SFI may override the second TDD pattern carried in RRC. The overriding method can refer to the aforementioned methods 1 - 4. For example, at least one of the configurations of the uplink time unit, downlink time unit, and flexible time unit in the second TDD pattern may be overridden.

[0107] For example, when a network - side device such as a base station configures a TDD configuration by RRC Repeater for this purpose, the network - side device such as a base station may transmit an SFI (i.e., DCI format 2_0) to rewrite a flexible symbol, etc. in the upper - layer TDD configuration.

[0108] Also, RRC may include at least one of cell - specific RRC signaling, UE - dedicated signaling, MT - dedicated signaling, and repeater - dedicated signaling.

[0109] (405) When the first information is transmitted by the first SFI, the fourth information is transmitted by the second SFI.

[0110] That is, the first TDD pattern carried by the first SFI may override the second TDD pattern carried by the second SFI, and the overriding method may refer to the aforementioned methods 1-4. For example, at least one of the uplink time unit, downlink time unit, and flexible time unit in the second TDD pattern may be overridden.

[0111] In one implementation, considering that the types of SFI may be various, when the first information described in (405) is transmitted by the first SFI and the fourth information is transmitted by the second SFI information, the first SFI and the second SFI may include at least one of the following (4050)-(4053).

[0112] (4050) When the first SFI is a UE dedicated SFI, the second SFI is a UE dedicated SFI.

[0113] That is, the first TDD pattern carried by the new UE dedicated SFI may override the second TDD pattern carried by the previously memorized or received UE dedicated SFI, and the overriding method may refer to the aforementioned methods 1-4. For example, 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 may be overridden.

[0114] (4051) When the first SFI is an MT dedicated SFI or a repeater dedicated SFI, the second SFI is a UE dedicated SFI.

[0115] That is, the first TDD pattern carried in the MT dedicated SFI or the repeater dedicated SFI may override the second TDD pattern carried in the previously memorized or received UE dedicated SFI. The overriding method may refer to the aforementioned methods 1-4. For example, 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 may be overridden.

[0116] (4052) When the first SFI is the MT dedicated SFI or the repeater dedicated SFI, the second SFI is the MT dedicated SFI or the repeater dedicated SFI.

[0117] That is, the first TDD pattern carried in the MT dedicated SFI or the repeater dedicated SFI may override the second TDD pattern carried in the previously memorized or received MT dedicated SFI or repeater dedicated SFI. The overriding method may refer to the aforementioned methods 1-4. For example, 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 may be overridden.

[0118] (4053) When the first SFI is the UE dedicated SFI, the second SFI is the MT dedicated SFI or the repeater dedicated SFI.

[0119] That is, the first TDD pattern carried by the UE dedicated SFI may override the second TDD pattern carried by the previously memorized or received MT dedicated SFI or repeater dedicated SFI. For the overriding method, the above-mentioned methods 1-4 can be referred to. For example, at least one of the configurations of the uplink time unit, the downlink time unit, and the flexible time unit in the second TDD pattern may be overridden.

[0120] As can be understood, the first SFI described above may be a new SFI, and the second SFI may be the previously memorized or previously received SFI. That is, the first TDD pattern carried by the newly received valid SFI may override the second TDD pattern carried by the previously memorized or previously received SFI. Or, the first TDD pattern carried by the newly received valid SFI may override the configuration of some time units of the second TDD pattern within the time domain corresponding to the previously memorized or previously received SFI.

[0121] It should be noted that when the new SFI (for example, the first SFI) can simultaneously indicate the TDD configuration, such as the UL / DL configuration, for a plurality of repeaters, the DCI (representing the scheduling signaling) can only indicate the UL / DL information for a specific repeater. It should be noted that the new SFI is for matching the situation where the network-side device dynamically schedules the flexible symbols in the UL / DL UE, Repeater and it is necessary to know whether it is UL amplification or DL amplification at these positions in order to match the corresponding parameters such as beam / power control.

[0122] Furthermore, when the first information is transmitted by the third information based on the different transmission information given in the foregoing (301)-(307), the type of the third information is related to whether the Repeater is in a connected state.

[0123] For example, when the Repeater is in a non-connected state, the third information may be at least one of SIB, MIB, and PDCCH. That is, when the Repeater is in a non-connected state, the first information may be transmitted by at least one of SIB, MIB, and PDCCH.

[0124] Also, for example, when the Repeater 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 Repeater is in a connected state, the first information may be transmitted by at least one of F1 signaling, SIB, MIB, PDCCH, RRC, MAC CE, and SFI.

[0125] In addition, in this embodiment, the determination method of the activation time of the third information for transmitting the first information may be various. For example, the determination process will be described below by combining (501)-(503).

[0126] (501) The activation time of the third information is determined based on the first time unit and the first numerical value at which the third information is received.

[0127] For example, if the first numerical value is L, and the Repeater receives the third information at time unit n, the activation time of the first information indicated by the third information may be time unit n + L.

[0128] Also, for example, if the first numerical value is L, and the RepeaterIf it is assumed that the first information indicated by the third information is used at the time unit n, the reception time unit of the third information may be the time unit n-L.

[0129] Optionally, the first numerical value is related to the subcarrier spacing (SCS), or the first numerical value is realized by an indication from the network side, an agreement by a protocol, a configuration by a higher layer, etc., and is indicated by, for example, the third information, etc., without limitation here.

[0130] As can be understood, when the first numerical value is related to the SCS, the relationship between the first numerical value and the SCS may be defined in advance. For example, when SCS = 15 kHz, the first numerical value is K1; when SCS = 30 kHz, the first numerical value is K2; when SCS = 60 kHz, the first numerical value is K3; when SCS = 120 kHz, the first numerical value is K4. In this case, when it is necessary to determine the activation time of the third information, the first numerical value may be determined based on the relationship between the first numerical value and the SCS defined in advance.

[0131] It should be noted that the time units mentioned in this embodiment and subsequent embodiments may be sub-slots, slots, sub-frames, frames, symbols, seconds (s), milliseconds (ms), etc., without limitation here.

[0132] (502) The activation time of the third information is determined based on the first indication information transmitted by the network side device.

[0133] For example, in the first indication information, the activation time of the third information may be indicated implicitly or explicitly.

[0134] (503) The activation time of the third information is determined based on the reception time of the next third information.

[0135] Here, the activation time of the third information is from the activation start time of the third information until the next valid third information is received.

[0136] For example, if the third information is SFI, the activation time of the SFI may be from the time when the SFI is received until the time when the next valid SFI is received. That is, the Repeater may adopt the configuration information of this SFI to determine the transmission behavior until the next valid SFI is received. Here, the valid SFI may be understood as DCI format 2-0 or new SFI format.

[0137] Also, for example, if the third information is F1-AP or RRC, the activation time of this F1-AP or RRC may be from the time when the F1-AP or RRC is received until the time when the next valid F1-AP or RRC is received.

[0138] It should be noted that in the foregoing (501)-(503), the activation time may include the activation start time, activation end time, activation duration, activation period, etc. of the third information, and is not limited here. Also, the activation time of the third information may be understood as the activation time of the first information.

[0139] Based on the description of the foregoing content, an example is hereinafter combined to describe the update of the foregoing configuration information and the determination of the activation time, and the content is as follows.

[0140] Example: Assume that a network-side device such as a base station configures a TDD pattern by RRC Repeater for this purpose. Then, a network-side device such as a base station may transmit SFI (i.e., DCI format 2_0) to rewrite (update) the flexible symbol in the upper-layer TDD configuration. In this case, the RepeaterIt may monitor the SFI transmitted by a network-side device such as a base station and determine the configuration of its UL / DL / flexible symbol. Here, the Repeater may determine the TDD configuration within a certain period based on the indication in the SFI. For example, Repeater adopts the configuration of this SFI until the next valid SFI is received. This valid SFI is DCI format 2-0 or new SFI (i.e., repeater specific / MT specific SFI).

[0141] S320, the Repeater performs signal transmission based on the transmission behavior.

[0142] As can be understood, the implementation process of S320 can refer to the relevant description in Embodiment 200 of the method. To avoid repetition of the description, it will not be further described here.

[0143] In this embodiment, the transmission of the first information is realized by configuring different signaling, thereby improving the flexibility and reliability of the transmission of the first information and further ensuring the wireless communication quality.

[0144] As shown in FIG. 5, it is a flowchart of a signal transmission method 500 according to an exemplary embodiment of the present application. This method 500 may be Repeater executed by, but not limited to, specifically Repeater it may also be executed by the hardware and / or software installed in. In this embodiment, the method 500 may at least include the following steps.

[0145] S510, Repeater determines the transmission behavior based on the first information.

[0146] Here, the first information includes TDD configuration information and / or data scheduling information.

[0147] For better understanding, in addition to being able to refer to the relevant descriptions in Embodiment 200 or 300 of the foregoing method for the implementation process of S510, as one possible implementation manner, referring to FIG. 5 again, the implementation process of the said S510 may further include S511, and the content is as follows.

[0148] S511, Repeater determines the transmission behavior within the target time unit based on the first information.

[0149] In one implementation manner, for the repeater to determine the transmission behavior in the target time unit based on the first information, it includes any one of the following (601)-(606).

[0150] (601) When the first information determines that the target time unit is a flexible time unit, the Repeater transmission behavior in the said target time unit is an uplink transmission.

[0151] For example, when the resource is configured as a flexible symbol, Repeater it tacitly assumes that this symbol is a UL symbol, and based on this UL symbol, it receives, amplifies, and transfers the uplink signal.

[0152] (602) When the first information determines that the target time unit is a flexible time unit, the Repeater transmission behavior in the said target time unit is a downlink transmission.

[0153] For example, when the resource is configured as a flexible symbol, Repeater it tacitly assumes that this symbol is a DL symbol, and based on this DL symbol, it receives, amplifies, and transfers the downlink signal.

[0154] (603) When the first information determines that the target time unit is a flexible time unit, theRepeater The transmission behavior in the target time unit is non - transmission.

[0155] For example, when the resource is configured as a flexible symbol, Repeater in order to avoid interference, reception, amplification, and transfer of uplink / downlink signals are not performed in this flexible symbol.

[0156] (604) When it is determined that the first information indicates that the target time unit is a flexible time unit and no first indication signaling is received, the Repeater transmission behavior in the target time unit is non - transmission.

[0157] For example, when the resource is configured as a flexible symbol, Repeater if no uplink / downlink direction indication or base station scheduling indication (i.e., first indication signaling) for this flexible symbol is received, the repeater does not perform reception, amplification, and transfer of uplink / downlink signals in this flexible symbol to avoid interference.

[0158] Here, the first indication signaling is used for the base station to indicate whether the flexible symbol of the smart Repeater is for UL amplification or DL amplification.

[0159] (605) When it is determined that the first information indicates that the target time unit is a flexible time unit and second indication signaling is received, but the second indication signaling indicates that the target time unit is a flexible time unit, the Repeater transmission behavior in the target time unit is non - transmission.

[0160] For example, when the resource is configured as a flexible symbol, RepeaterWhen receiving an uplink / downlink direction indication or a base station scheduling indication (i.e., the second indication signaling) for this flexible symbol, if this uplink / downlink direction indication or base station scheduling indication indicates that the flexible symbol is a flexible time unit, Repeater To avoid interference, reception, amplification, and transfer of uplink / downlink signals are not performed in this flexible symbol.

[0161] (606) When the first information determines that the target time unit is a flexible time unit, has received the second indication signaling, and the second indication signaling indicates that the target time unit is neither uplink nor downlink, the Repeater transmission behavior in the target time unit is non - transmission.

[0162] Here, the implementation process of (606) can refer to the description of the terminal in the aforementioned (605). To avoid repetition of the description, it will not be further described herein.

[0163] Furthermore, in this embodiment, when the Repeater does not receive the first information, at least one of the following (701)-(702) may be executed.

[0164] (701) Transmit a TDD pattern request to the network - side device.

[0165] Here, the TDD pattern request is used to request the network - side device for the first information, such as dedicated TDD configuration information or data scheduling information, etc.

[0166] (702) Determine the transmission behavior based on the specified TDD configuration information, which is the TDD configuration information configured by the network - side device for the terminal.

[0167] That is, the RepeaterIt may directly use the TDD configuration information configured for a normal UE received in SIB1 and cell specific RRC, and determine the transmission behavior based on this TDD configuration information.

[0168] It should be noted that after determining the transmission behavior based on the specified TDD configuration, when the Repeater receives the first information transmitted by the network side device, the Repeater shall stop executing the step of determining the transmission behavior based on the specified TDD configuration and the step of determining the transmission behavior based on the first information. That is, Repeater when receiving the dedicated TDD configuration information transmitted by the network side device, it shall abandon the use of the TDD configuration information for a normal UE received in SIB1, and use the newly received dedicated TDD configuration information to determine the transmission behavior.

[0169] Furthermore, in one implementation manner, assuming that the first information is transmitted by SFI, Repeater when the Repeater receives SFI configurations from multiple network side devices (for example, donor nodes), the Repeater requires that among the multiple SFIs corresponding to the same slot / symbol, there is at most one SFI indicating DL / UL, and the other SFIs indicate flexible, or Repeater considering that the Repeater can only provide services to one network side device at a time, in this case, when the

[0170] receives SFIs (i.e., the first information) transmitted from multiple network side devices, the

[0171] Here, "not supported" and "refused" in this embodiment may be understood as prohibited, suspended, released, etc., and are not limited here.

[0172] (802) Do not support or refuse that a plurality of the first information indicates that the target time unit is uplink transmission and downlink transmission.

[0173] (803) Support that a plurality of the first information indicates that the target time unit is an uplink time unit or a downlink time unit or a flexible time unit.

[0174] (804) Determine the first information used for determining the transmission behavior from at least two of the first information based on a preset rule.

[0175] Here, the preset rule may be realized by an agreement based on a protocol, a configuration by an upper layer, or a configuration by a network-side device, and is not limited here. As a possible implementation method, determining the first information used for determining the transmission behavior from at least two of the first information based on the aforementioned preset rule may include at least one of the following (9041)-(9042).

[0176] (9041) Determine the first information used for determining the transmission behavior from at least two of the first information based on the identifier information of each network-side device.

[0177] (9042) Determine the first information used for determining the transmission behavior from at least two of the first information based on the priority information of each network-side device.

[0178] Based on this, the RepeaterPerforms uplink transmission or downlink transmission based on target transmission configuration indicator (TCI) information, where the target TCI information is the TCI information of the network device that transmits the determined first information.

[0179] S520, the Repeater Performs signal transmission based on the transmission behavior.

[0180] Here, as can be understood, the implementation process of S520 can refer to the relevant description in Example 200 of the method, and in order to avoid repetition of the description, it will not be further described here.
