[0002] In order to improve communication efficiency, related technologies have proposed full-duplex communication. For example, by setting an uplink (UL) subband for a terminal in a downlink (DL) slot, the terminal can transmit information to a network-side device in the uplink subband of the downlink slot, and can receive information transmitted from the network device in a portion of the downlink slot other than the uplink subband, thereby realizing full-duplex communication.

[0003] In addition, in order to improve transmission reliability, a repetition technique has been proposed in related art, which allows the same information to be transmitted repeatedly, and each transmission in the repetition can be arranged in a different slot.

[0020] 1 is a schematic flowchart of a repeat transmission method according to an embodiment of the present disclosure. The repeat transmission method illustrated in this embodiment can be performed by a terminal, including but not limited to communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices. The terminal can communicate with network devices, including but not limited to network devices of communication systems such as base stations and core networks of 4G, 5G, and 6G.

[0021] As shown in FIG. 1, the repeat transmission method can include the following steps:

[0022] In step S101, a first time domain unit for full-duplex communication and / or a second time domain unit not for full-duplex communication is determined, where the first time domain unit is also called a Subband Full Duplex (SBFD) slot, and correspondingly the second time domain unit is also called a normal slot.

[0023] In step S102, a first frequency domain resource for repeated transmission is determined.

[0024] In step S103, if the first frequency domain resources of the repeated transmission in the first time domain unit are not all located in the subbands of the first time domain unit, process the first frequency domain resources to determine second frequency domain resources that are all located in the subbands of the first time domain unit, and perform repeated transmission on the second frequency domain resources within the first time domain unit; and / or In step S104, if the first frequency domain resources for repeated transmission in the second time domain unit are not all located in the active bandwidth portion of the second time domain unit, the first frequency domain resources are processed to determine third frequency domain resources that are all located in the active bandwidth portion of the second time domain unit, and repeated transmission is performed on the third frequency domain resources within the second time domain unit.

[0025] In one embodiment, the time domain unit may be one or more system frames, the time domain unit may be one or more subframes, the time domain unit may be one or more slots, or the time domain unit may be one or more symbols, for example, Orthogonal Frequency Division Multiplexing (OFDM) symbols.

[0026] In one embodiment, the first frequency domain resource for repeated transmission configured for the terminal by the network device is the same in each repeated transmission, so that the terminal can determine the frequency domain resource for each repeated transmission based on the frequency domain resource of the initial transmission in the repeated transmission.

[0027] In one embodiment, each repeat transmission may be located in a different slot, and the slot may include a first time domain unit used for full-duplex communication and a second time domain unit not used for full-duplex communication.

[0028] In the second time domain unit, the terminal may perform repeated transmission in an active bandwidth portion (active BWP) according to the scheduling of the network device.

[0029] In the first time domain unit, the frequency domain resources include an active bandwidth portion and a subband, and the terminal can repeatedly transmit in the subband according to scheduling by the network device. The subband is not necessarily located within the active bandwidth portion. For example, the subband may be located entirely within the active bandwidth portion, partially within the bandwidth portion, or entirely outside the bandwidth portion.

[0030] When the repeated transmissions include repeated transmissions in a first time domain unit and repeated transmissions in a second time domain unit, some technical problems may exist, since the first time domain unit does not represent a single slot but is used to represent one type of slot, and similarly the second time domain unit does not represent a single slot but is used to represent one type of slot.

[0031] Although the active bandwidth portion corresponding to each slot may be the same, since subbands are configured only in the first time domain unit, the following cases may occur:

[0032] Case 1: The initial transmission is located in the second time domain unit, a repeat transmission is located in the first time domain unit, and the first frequency domain resources used for the repeat transmission are all located in the active bandwidth portion, but not all located in the subband.

[0033] Case 2: The initial transmission is located in the first time domain unit, a repeat transmission is located in the second time domain unit, and the first frequency domain resources used for the repeat transmission are all located in subbands, but not all located in the active bandwidth portion.

[0034] For the above case 1, in the first time domain unit, the terminal performs repeated transmission in the subband according to the scheduling of the network device. Therefore, if the first frequency domain resources of the repeated transmission are all allocated to the active bandwidth portion but not all allocated to the subband, the first frequency domain resources can be processed to determine second frequency domain resources that are all allocated to the subband. Furthermore, when performing repeated transmission in the first time domain unit, using the second frequency domain resources to perform the repeated transmission can ensure that the terminal can smoothly complete the repeated transmission.

[0035] For the above Case 2, in the second time domain unit, the terminal performs repeated transmission in the active bandwidth portion according to the scheduling of the network device. Therefore, if the first frequency domain resources of the repeated transmission are all allocated to subbands but not all allocated to the bandwidth portion, the first frequency domain resources can be processed to determine third frequency domain resources that are all allocated to subbands. Furthermore, when performing repeated transmission in the second time domain unit, using the third frequency domain resources to perform the repeated transmission can ensure that the terminal can smoothly complete the repeated transmission.

[0036] According to an embodiment of the present disclosure, by processing the first frequency domain resource used for repeated transmission, it is possible to ensure that repeated transmission is performed on the second frequency domain resource, all of which are located within the subband in the first time domain unit, and that repeated transmission is performed on the third frequency domain resource, all of which are located within the active bandwidth portion in the second time domain unit, thereby ensuring that the terminal can complete the repeated transmission smoothly.

[0037] In one embodiment, the first time domain unit comprises: an uplink slot including a downlink subband; a flexible slot including a downlink subband; a downlink slot including an uplink subband; a flexible slot including an uplink subband.

[0038] For example, in a downlink slot including an uplink subband, a terminal can realize full-duplex communication by performing uplink communication in the uplink subband and performing downlink communication in frequency domain resources outside the uplink subband. For example, in a flexible slot including an uplink subband, a terminal can realize full-duplex communication by performing uplink communication in the uplink subband and performing downlink communication in frequency domain resources outside the uplink subband. For example, in an uplink slot including a downlink subband, a terminal can realize full-duplex communication by performing downlink communication in the downlink subband and performing uplink communication in frequency domain resources outside the downlink subband. For example, in a flexible slot including a downlink subband, a terminal can realize full-duplex communication by performing downlink communication in the downlink subband and performing uplink communication in frequency domain resources outside the downlink subband.

[0039] How to determine the first time domain unit can be set as needed, including, but not limited to, the methods shown in the following examples.

[0040] In one embodiment, the network device may first set the transmission direction of the first time domain unit, e.g., the first transmission direction, through first information, where the first information includes, but is not limited to, a Time Division Duplexing (TDD) uplink and downlink configuration and a slot format indication (SFI). In this embodiment, the first information is carrier-level, that is, the first information is applicable to all BWPs in the same carrier. Based on the first information, the terminal may determine whether the first time domain unit is an uplink slot (the first transmission direction is uplink) or a downlink slot (the first transmission direction is downlink).

[0041] In a subsequent communication process, the network device can adjust the transmission direction of the terminal in the first time domain unit through the second information. For example, the network device can indicate through the second information that the transmission direction of the terminal in the first time domain unit is the second transmission direction, where the second information may be dynamic scheduling signaling or semi-static configuration information such as Radio Resource Control (RRC) signaling.

[0042] Because the second transmission direction is different from the first transmission direction, when the terminal determines that the transmission direction in the first time domain unit is the second transmission direction based on the second information, the terminal can determine that the first time domain unit is the first time domain unit. For example, when the first transmission direction is uplink transmission and the second transmission direction is downlink transmission, the terminal can determine that the first time domain unit is an uplink slot including a downlink subband, and when the first transmission direction is downlink transmission and the second transmission direction is uplink transmission, the terminal can determine that the first time domain unit is a downlink slot including an uplink subband.

[0043] In one embodiment, the network device can first set the transmission direction of the first time domain unit, for example, the first transmission direction, through the TDD UL-DL configuration of the cell, where the TDD UL-DL configuration of the cell is at the cell level (carrier level) and is the same for all BWPs of the same carrier.The terminal can determine, based on the first information, whether the first time domain unit is an uplink slot (the first transmission direction is uplink) or a downlink slot (the first transmission direction is downlink).

[0044] In a subsequent communication process, the network device can adjust the transmission direction of the terminal in the first time domain unit through the TDD UL-DL configuration of the preset BWP pair. For example, the network device can indicate that the transmission direction of the terminal in the first time domain unit is the second transmission direction through the TDD UL-DL configuration of the preset BWP pair. The TDD UL-DL configuration of the preset BWP pair is at the BWP level, that is, it can be different for each BWP.

[0045] In this case, the terminal may maintain two activated BWP pairs, one of which is a preset BWP pair and the other of which is a BWP pair other than the preset BWP pair and may be called a normal BWP pair. The two BWP pairs may correspond to different TDD UL-DL configurations, and the terminal may determine the transmission direction in the first time domain unit according to the TDD UL-DL configuration of the preset BWP pair.

[0046] In the two BWP pairs, the frequency domain resources corresponding to the uplink BWP and the downlink BWP may be the same or different. For communication in the first time domain unit, the frequency domain resources are determined according to the frequency domain resources corresponding to the uplink BWP and / or the downlink BWP in the preset BWP pair, and for communication in a unit other than the first time domain unit, the frequency domain resources are determined according to the frequency domain resources corresponding to the uplink BWP and / or the downlink BWP in the normal BWP pair.

[0047] The network device can also indicate a preset BWP pair among at least one BWP pair by sending indication information. The network device can send a BWP-level TDD UL-DL configuration to the terminal, so that each BWP pair corresponds to a TDD UL-DL configuration. Therefore, the network device needs to notify the terminal of a preset BWP pair from among multiple BWP pairs through indication information, so that the terminal determines the second transmission direction according to the TDD UL-DL configuration of the preset BWP pair. The preset BWP pair may also be called a reference BWP pair or an SBFD BWP pair.

[0048] Because the second transmission direction is different from the first transmission direction, when the terminal determines that the transmission direction in the first time domain unit is the second transmission direction based on the second information, the terminal can determine that the first time domain unit is the first time domain unit. For example, when the first transmission direction is uplink transmission and the second transmission direction is downlink transmission, the terminal can determine that the first time domain unit is an uplink slot including a downlink subband, and when the first transmission direction is downlink transmission and the second transmission direction is uplink transmission, the terminal can determine that the first time domain unit is a downlink slot including an uplink subband.

[0049] In one embodiment, it may be specified that full-duplex operation is performed on semi-static time domain resources (e.g., symbols, slots) of the TDD frequency band or time domain resources indicated by an SFI, and then a slot included in the time domain resource or in which the time domain resource is located may be used as the first time domain unit.

[0050] The semi-static time domain resource may be determined based on the tdd-UL-DL-ConfigurationCommon signaling transmitted from the base station, or may be determined based on the tdd-UL-DL-ConfigurationCommon signaling and the tdd-UL-DL-ConfigurationDedicated signaling transmitted from the base station. Furthermore, the network device can indicate a transmission direction (e.g., uplink communication, downlink communication, etc.) in the first time domain unit. For example, taking a downlink time domain resource as an example, the network device can indicate a transmission direction of the terminal in the downlink time domain resource in the following two ways:

[0051] Method 1: In downlink time domain resources, a network device configures an UL subband or a DL subband for the terminal, in which the terminal can only perform uplink transmission in the UL subband and can only perform uplink reception in the DL subband. Method 2: In downlink time domain resources, a network device configures an UL subband or a DL subband for the terminal, and schedules a data channel or instructs a reference signal in the UL subband or DL ​​subband, and the terminal determines whether to perform uplink communication or downlink communication according to the instruction.

[0052] The processing of the first frequency domain resource mainly includes several methods such as offset in the frequency domain, interleaving, frequency hopping (FH), etc. These methods are exemplified by several examples below.

[0053] 2 is a schematic flowchart of another repeat transmission method according to an embodiment of the present disclosure. As shown in FIG. 2, the first time domain unit includes an uplink slot or a flexible slot including a downlink subband, and processing the first frequency domain resources to determine second frequency domain resources, all of which are located in the subbands of the first time domain unit, includes the following steps:

[0054] In step S201, if the repeated transmission is a non-interleaved downlink transmission, offsetting the first frequency domain resource in the frequency domain to be offset to a downlink subband of the first time domain unit, where the offset first frequency domain resource is the second frequency domain resource; and / or In step S202, if the repeated transmission is an interleaved downlink transmission, perform an interleaving operation on the downlink subbands of the first time domain unit to interleave the first frequency domain resource into the downlink subbands of the first time domain unit, and the interleaved first frequency domain resource is the second frequency domain resource.

[0055] In one embodiment, for an uplink slot or flexible slot including a downlink subband, if the repeated transmission is a non-interleaved downlink transmission, such as a type 0 Random Access (RA) Physical Downlink Shared Channel (PDSCH) or a type 1 RA PDSCH without interleaving (non-interleaving), the first frequency domain resources may be offset if all of the first frequency domain resources are located in the active bandwidth portion but not all of the first frequency domain resources are located in the downlink subband. By performing the offset in the frequency domain, all of the first frequency domain resources in the first time domain unit may be offset to the downlink subband to become the second frequency domain resources.

[0056] It should be noted that the amplitude of the offset for the first frequency domain resource is indicated by the network device or determined based on a protocol agreement.

[0057] In one embodiment, for an uplink slot or flexible slot including a downlink subband, if the repeated transmission is an interleaved downlink transmission, e.g., type 1 RA PDSCH with interleaving (interleaving is on), and if all first frequency domain resources are allocated to the active bandwidth portion but not all to the downlink subband, an interleaving operation can be performed within the downlink subband of the first time domain unit. By performing the interleaving operation, all first frequency domain resources in the first time domain unit can be interleaved into the downlink subband to become second frequency domain resources.

[0058] 3 is a schematic flowchart of another repeat transmission method according to an embodiment of the present disclosure. As shown in FIG. 3, the first time domain unit includes a downlink slot or a flexible slot including an uplink subband, and processing the first frequency domain resources to determine second frequency domain resources, all of which are located in the subbands of the first time domain unit, includes the following steps:

[0059] In step S301, if the repeated transmission is a non-frequency hopping uplink transmission, offsetting the first frequency domain resource in the frequency domain to be offset to an uplink subband of the first time domain unit, where the offset first frequency domain resource is the second frequency domain resource; and / or In step S302, if the repeated transmission is a frequency-hopping uplink transmission, perform a frequency hopping operation in the uplink subband of the first time domain unit to frequency-hop the first frequency domain resource to the downlink subband of the first time domain unit, and the interleaved first frequency domain resource is the second frequency domain resource.

[0060] In one embodiment, for a downlink slot or flexible slot including an uplink subband, if the repeated transmission is a non-frequency-hopping uplink transmission, such as a Physical Uplink Shared Channel (PUSCH) with or without FP (non-frequency-hopping), the first frequency-domain resources can be offset if they are all located in the active bandwidth portion but not all located in the uplink subband. By performing the offset in the frequency domain, all first frequency-domain resources in the first time-domain unit can be offset to the downlink subband to become the second frequency-domain resources.

[0061] In one embodiment, for a downlink slot or flexible slot including an uplink subband, if the repeated transmission is a frequency-hopping uplink transmission, e.g., type 1 RA PUSCH with FP (frequency hopping is on), and if all first frequency domain resources are located in the active bandwidth portion but not all in the uplink subband, a frequency hopping operation can be performed within the downlink subband of the first time domain unit. By performing the frequency hopping operation, all first frequency domain resources in the first time domain unit can be frequency hopped to the downlink subband to become the second frequency domain resources.

[0062] FIG. 4 is a schematic diagram of frequency domain resources according to an embodiment of the present disclosure.

[0063] As shown in Figure 4, taking five slots as an example, the slot structure is DDFUU, where D represents the downlink slot, F represents the flexible slot, and U represents the uplink slot. The slot structure can be determined according to the cell-specific tdd-UL-DL-ConfigurationCommon.

[0064] The second slot is the first time domain unit and can be used for full-duplex communication, and includes the uplink subband, but the uplink subband is outside the active bandwidth portion. The third and fourth slots are the second time domain unit and are used for uplink transmission instead of full-duplex communication.

[0065] For example, if the first frequency domain resources used for repeated transmissions are all located in the active bandwidth portion but not all located in the uplink subband, and the repeated transmissions are non-frequency hopping uplink transmissions, the first frequency domain resources can be offset in the first time domain unit and the first frequency domain resources can be offset to the uplink subband to obtain the second frequency domain resources. The second frequency domain resources and the first frequency domain resources may have the same frequency domain range but different starting positions.

[0066] Furthermore, the terminal still performs repeated transmission on the first frequency domain resource in the third and fourth slots, and performs repeated transmission on the second frequency domain resource in the second slot.

[0067] 5 is a schematic flowchart of another repeat transmission method according to an embodiment of the present disclosure. As shown in FIG. 5, processing the first frequency domain resources to determine third frequency domain resources, all of which are located in the active bandwidth portion of the second time domain unit, includes the following steps:

[0068] In step S501, if the repeated transmission is a non-interleaved downlink transmission, offsetting the first frequency domain resource in the frequency domain to be offset to a downlink subband of the second time domain unit, where the offset first frequency domain resource is the third frequency domain resource; and / or In step S502, if the repeated transmission is an interleaved downlink transmission, perform an interleaving operation within the downlink bandwidth portion of the second time domain unit to interleave the first frequency domain resource into the downlink bandwidth portion of the second time domain unit, and the interleaved first frequency domain resource is the third frequency domain resource.

[0069] In one embodiment, for the second time domain unit, if the repeated transmission is a non-interleaved downlink transmission, such as a type0 RA PDSCH, a type1 RA PDSCH without interleaving, and the first frequency domain resources are all located in the downlink subbands but not all located in the active bandwidth portion, the first frequency domain resources can be offset. By performing the offset in the frequency domain, all the first frequency domain resources in the first time domain unit can be offset into the active bandwidth portion to become the third frequency domain resources.

[0070] In one embodiment, for a second time domain unit, if the repeated transmission is an interleaved downlink transmission, e.g., type 1 RA PDSCH with interleaving, and if all of the first frequency domain resources are allocated to downlink subbands but not all of them are allocated to the active bandwidth portion, an interleaving operation can be performed within the active bandwidth portion of the first time domain unit, such that all of the first frequency domain resources in the first time domain unit can be interleaved into the active bandwidth portion to form third frequency domain resources.

[0071] 6 is a schematic flowchart of another repeat transmission method according to an embodiment of the present disclosure. As shown in FIG. 6, processing the first frequency domain resources to determine third frequency domain resources, all of which are located in the active bandwidth portion of the second time domain unit, includes the following steps:

[0072] In step S601, if the repeated transmission is a non-frequency hopping uplink transmission, offsetting the first frequency domain resource in the frequency domain to be offset to an uplink bandwidth portion of the second time domain unit, the offset first frequency domain resource being the third frequency domain resource; and / or In step S602, if the repeated transmission is a frequency-hopping uplink transmission, perform a frequency hopping operation within the uplink bandwidth portion of the second time domain unit to frequency hop the first frequency domain resource to the downlink bandwidth portion of the second time domain unit, and the interleaved first frequency domain resource is the third frequency domain resource.

[0073] In one embodiment, for the second time domain unit, if the repeated transmission is a non-frequency hopping uplink transmission, such as a PUSCH with / without FP, the first frequency domain resources may be offset if they are all located in the uplink subband but not all located in the active bandwidth portion. By performing the offset in the frequency domain, all the first frequency domain resources in the first time domain unit may be offset into the active bandwidth portion to become the third frequency domain resources.

[0074] In one embodiment, for a second time domain unit, if the repeated transmission is a frequency-hopping uplink transmission, e.g., type 1 RA PUSCH with FP, and if all of the first frequency domain resources are allocated to uplink subbands but not all of them are allocated to the active bandwidth portion, a frequency hopping operation can be performed within the active bandwidth portion of the first time domain unit, by frequency hopping all of the first frequency domain resources in the first time domain unit to downlink subbands to become third frequency domain resources.

[0075] FIG. 7 is a schematic diagram of another frequency domain resource according to an embodiment of the present disclosure.

[0076] As shown in FIG. 7, taking five slots as an example, for example, the slot structure is DDFUU, where D represents the downlink slot, F represents the flexible slot, and U represents the uplink slot.

[0077] The second slot is the first time domain unit and can be used for full-duplex communication, and includes an uplink subband, but the uplink subband is outside the active bandwidth portion. The third and fourth slots are the second time domain unit and are used for downlink transmission instead of full-duplex communication.

[0078] For example, if the first frequency domain resources used for repeated transmissions are all located within the uplink subband but not all located within the active bandwidth portion, and the repeated transmissions are non-frequency hopping uplink transmissions, the first frequency domain resources can be offset within the second time domain unit and the first frequency domain resources can be offset into the active bandwidth portion to obtain the third frequency domain resources. The third frequency domain resources and the first frequency domain resources may have the same frequency domain range but different starting positions.

[0079] Furthermore, the terminal performs repeated transmission on the third frequency domain resource in the third and fourth slots, and still performs repeated transmission on the first frequency domain resource in the second slot.

[0080] FIG. 8 is a schematic diagram of yet another frequency domain resource according to an embodiment of the present disclosure.

[0081] As shown in FIG. 8, taking five slots as an example, for example, the slot structure is DDFUU, where D represents the downlink slot, F represents the flexible slot, and U represents the uplink slot.

[0082] The first slot is the first time domain unit, which can be used for full-duplex communication and contains the uplink subband, but the uplink subband is outside the active bandwidth portion. The second slot is the second time domain unit, which is not full-duplex and is used only for downlink transmission.

[0083] For example, if the first frequency domain resources used for repeated transmission are all located in the uplink subband and are all located in the active bandwidth portion, there is no need to process the first frequency domain resources, i.e., the terminal performs repeated transmission on the first frequency domain resources in both the first slot and the second slot.

[0084] 9 is a schematic flowchart of a repeat transmission method according to an embodiment of the present disclosure. The repeat transmission method illustrated in this embodiment can be performed by a network device, which can communicate with a terminal, including but not limited to a base station in a communication system such as a 4G base station, a 5G base station, or a 6G base station, and the terminal can include but not limited to a communication device such as a mobile phone, a tablet computer, a wearable device, a sensor, or an Internet of Things device.

[0085] As shown in FIG. 9, the repeat transmission method may include the following steps:

[0086] In step S901, a first time domain unit used for full-duplex communication of a terminal and / or a second time domain unit not used for full-duplex communication is determined.

[0087] In step S902, the terminal determines a first frequency domain resource to be used for repeated transmission.

[0088] In step S903, if the first frequency domain resources of the repeated transmission in the first time domain unit are not all located in the subbands of the first time domain unit, process the first frequency domain resources to determine second frequency domain resources that are all located in the subbands of the first time domain unit, and perform repeated transmission with the terminal on the second frequency domain resources in the first time domain unit; and / or In step S904, if the first frequency domain resources of the repeated transmission in the second time domain unit are not all located in the active bandwidth portion of the second time domain unit, the first frequency domain resources are processed to determine third frequency domain resources that are all located in the active bandwidth portion of the second time domain unit, and repeated transmission is performed with the terminal on the third frequency domain resources in the second time domain unit.

[0089] In one embodiment, the first frequency domain resource for repeated transmission configured for the terminal by the network device is the same in each repeated transmission, so that the terminal can determine the frequency domain resource for each repeated transmission based on the frequency domain resource of the initial transmission in the repeated transmission.

[0090] In one embodiment, each repeat transmission may be located in a different slot, and the slot may include a first time domain unit used for full-duplex communication and a second time domain unit not used for full-duplex communication.

[0091] In the second time domain unit, the terminal may perform repeated transmission in an active bandwidth portion (active BWP) according to the scheduling of the network device.

[0092] In the first time domain unit, the frequency domain resources include an active bandwidth portion and a subband, and the terminal can repeatedly transmit in the subband according to scheduling by the network device. The subband is not necessarily located within the active bandwidth portion. For example, the subband may be located entirely within the active bandwidth portion, partially within the bandwidth portion, or entirely outside the bandwidth portion.

[0093] When the repeated transmissions include repeated transmissions in a first time domain unit and repeated transmissions in a second time domain unit, some technical problems may exist, since the first time domain unit does not represent a single slot but is used to represent one type of slot, and similarly the second time domain unit does not represent a single slot but is used to represent one type of slot.

[0094] Although the active bandwidth portion corresponding to each slot may be the same, since subbands are configured only in the first time domain unit, the following cases may occur:

[0095] Case 1: The initial transmission is located in the second time domain unit, a repeat transmission is located in the first time domain unit, and the first frequency domain resources used for the repeat transmission are all located in the active bandwidth portion, but not all located in the subband.

[0096] Case 2: The initial transmission is located in the first time domain unit, a repeat transmission is located in the second time domain unit, and the first frequency domain resources used for the repeat transmission are all located in subbands, but not all located in the active bandwidth portion.

[0097] For the above case 1, in the first time domain unit, the terminal performs repeated transmission in the subband according to the scheduling of the network device. Therefore, if the first frequency domain resources of the repeated transmission are all arranged in the active bandwidth portion but not all arranged in the subband, the first frequency domain resources can be processed to determine second frequency domain resources that are all arranged in the subband. Furthermore, when performing repeated transmission in the first time domain unit, using the second frequency domain resources to perform the repeated transmission can ensure that the terminal can smoothly complete the repeated transmission.

[0098] For the above case 2, in the second time domain unit, the terminal performs repeated transmission in the active bandwidth portion according to the scheduling of the network device. Therefore, if the first frequency domain resources of the repeated transmission are all allocated to subbands but not all allocated to the bandwidth portion, the first frequency domain resources can be processed to determine third frequency domain resources that are all allocated to subbands. Furthermore, when performing repeated transmission in the second time domain unit, using the third frequency domain resources to perform the repeated transmission can ensure that the terminal can smoothly complete the repeated transmission.

[0099] According to an embodiment of the present disclosure, by processing the first frequency domain resource used for the repeated transmission, it is possible to ensure that the repeated transmission is performed in the second frequency domain resource, all of which are located within the subband in the first time domain unit, and the repeated transmission is performed in the third frequency domain resource, all of which are located within the active bandwidth portion in the second time domain unit, thereby ensuring that the network device can complete the repeated transmission smoothly.

[0100] In one embodiment, the first time domain unit comprises: an uplink slot including a downlink subband; a flexible slot including a downlink subband; a downlink slot including an uplink subband; a flexible slot including an uplink subband.

[0101] For example, in a downlink slot including an uplink subband, a terminal can realize full-duplex communication by performing uplink communication in the uplink subband and performing downlink communication in frequency domain resources other than the uplink subband. For example, in a flexible slot including an uplink subband, a terminal can realize full-duplex communication by performing uplink communication in the uplink subband and performing downlink communication in frequency domain resources other than the uplink subband. For example, in an uplink slot including a downlink subband, a terminal can realize full-duplex communication by performing downlink communication in the downlink subband and performing uplink communication in frequency domain resources other than the downlink subband. For example, in a flexible slot including a downlink subband, a terminal can realize full-duplex communication by performing downlink communication in the downlink subband and performing uplink communication in frequency domain resources other than the downlink subband.

[0102] In one embodiment, the first time domain unit includes an uplink slot or a flexible slot that includes a downlink subband, and processing the first frequency domain resources to determine second frequency domain resources, all of which are located in the subbands of the first time domain unit, comprises: If the repeated transmission is a non-interleaved downlink transmission, offsetting the first frequency domain resource in the frequency domain to be offset to a downlink subband of the first time domain unit, wherein the offset first frequency domain resource is the second frequency domain resource; and / or If the repeated transmission is an interleaved downlink transmission, performing an interleaving operation on the downlink subbands of the first time domain unit to interleave the first frequency domain resources into the downlink subbands of the first time domain unit, and the interleaved first frequency domain resources are the second frequency domain resources.

[0103] In one embodiment, for an uplink slot or flexible slot including a downlink subband, if the repeated transmission is a non-interleaved downlink transmission, such as a type0 RA PDSCH, a type1 RA PDSCH without interleaving, etc., the first frequency domain resources may be offset if they are all located in the active bandwidth portion but not all located in the downlink subband. By performing the offset in the frequency domain, all the first frequency domain resources in the first time domain unit may be offset to the downlink subband to become the second frequency domain resources.

[0104] In one embodiment, for an uplink slot or flexible slot including a downlink subband, if the repeated transmission is an interleaved downlink transmission, e.g., type 1 RA PDSCH with interleaving (interleaving is on), and if all first frequency domain resources are allocated to the active bandwidth portion but not all to the downlink subband, an interleaving operation can be performed within the downlink subband of the first time domain unit. By performing the interleaving operation, all first frequency domain resources in the first time domain unit can be interleaved into the downlink subband to become second frequency domain resources.

By performing the offset in the frequency domain, all the first frequency domain resources in the first time domain unit can be offset to the downlink subband to become the second frequency domain resources.

[0107] In one embodiment, for a downlink slot or flexible slot including an uplink subband, if the repeated transmission is a frequency-hopping uplink transmission, e.g., type 1 RA PUSCH w / FP, and if all first frequency domain resources are allocated to the active bandwidth portion but not all to the uplink subband, a frequency hopping operation may be performed within the downlink subband of the first time domain unit. By performing the frequency hopping operation, all first frequency domain resources in the first time domain unit may be frequency hopped to the downlink subband to become the second frequency domain resources.

[0108] In one embodiment, processing the first frequency domain resources to determine third frequency domain resources, all of which are located in an active bandwidth portion of the second time domain unit, comprises: If the repeated transmission is a non-interleaved downlink transmission, offsetting the first frequency domain resource in the frequency domain to be offset to a downlink subband of the second time domain unit, wherein the offset first frequency domain resource is the third frequency domain resource; and / or If the repeated transmission is an interleaved downlink transmission, performing an interleaving operation within the downlink bandwidth portion of the second time domain unit to interleave the first frequency domain resource into the downlink bandwidth portion of the second time domain unit, and the interleaved first frequency domain resource is the third frequency domain resource.

By performing the offset in the frequency domain, all the first frequency domain resources in the first time domain unit can be offset into the active bandwidth portion to become the third frequency domain resources.

[0110] In one embodiment, for a second time domain unit, if the repeated transmission is an interleaved downlink transmission, e.g., type 1 RA PDSCH with interleaving, and if all of the first frequency domain resources are allocated to downlink subbands but not all of them are allocated to the active bandwidth portion, an interleaving operation can be performed within the active bandwidth portion of the first time domain unit, such that all of the first frequency domain resources in the first time domain unit can be interleaved into the active bandwidth portion to form third frequency domain resources.
