Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and more specifically, to a repeated transmission method, a repeated transmission device, a communication device, and a computer-readable storage medium.

Background Art

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

[0003] Also, in order to improve the reliability of transmission, a repetition technology has been proposed in related technologies, and the same information can be repeatedly transmitted, and each transmission in the repeated transmission can be arranged in different slots. Since the frequency-domain resources of each repeated transmission are the same, there may be a problem that the frequency-domain resources are not all arranged in sub-bands or not all arranged in an active bandwidth part (BandWidth Part, BWP).

However, those skilled in the art can understand that the term "large" also includes the meaning of "above", "small" includes the meaning of "below", "high" includes the meaning of "above", and "low" includes the meaning of "below".

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

[0021] As shown in FIG. 1, the repeated 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 that is not for full-duplex communication is determined. Here, 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 all of the first frequency domain resources for repeated transmission are not arranged in the subbands of the first time domain unit in the first time domain unit, the first frequency domain resources are processed to determine a second frequency domain resource in which all are arranged in the subbands of the first time domain unit, and repeated transmission is performed in 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 are not all located in the active bandwidth portion of the second time domain unit, the first frequency domain resources are processed to determine a third frequency domain resource in which all are located in the active bandwidth portion of the second time domain unit, and repeated transmission is performed on the third frequency domain resource in the second time domain unit.

[0025] In one embodiment, a time-domain unit may be one or more system frames, one or more subframes, one or more slots, or one or more symbols, such as orthogonal frequency division multiplexing (OFDM) symbols.

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

[0027] In one embodiment, each repetitive transmission may be placed in a different slot, and the slot includes 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 can repeatedly perform transmissions in the active bandwidth portion (active BWP) according to the network device's scheduling.

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

[0030] If the repetitive transmission includes both a first time-domain unit and a second time-domain unit, several technical issues may arise. Note that the first time-domain unit is used to represent one type of slot, not one slot, and similarly, the second time-domain unit is also used to represent one type of slot, not one slot.

[0031] The active bandwidth portion corresponding to each slot may be the same, but since the subband is composed only of the first time-domain unit, the following cases may occur.

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

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

[0034] In Case 1 described above, in the first time-domain unit, the terminal repeatedly transmits in the subband according to the network device's scheduling. Therefore, if all of the first frequency-domain resources for repeated transmission are located in the active bandwidth portion but not all are located in the subband, the first frequency-domain resources can be processed to determine a second frequency-domain resource where all are located in the subband. Furthermore, when performing repeated transmission in the first time-domain unit, using the second frequency-domain resources for repeated transmission ensures that the terminal can complete the repeated transmission smoothly.

[0035] In the case of Case 2 described above, in the second time-domain unit, the terminal repeatedly transmits in the active bandwidth portion according to the network device's scheduling. Therefore, if all of the first frequency-domain resources for repeated transmission are located in the subband, but not all are located in the bandwidth portion, the first frequency-domain resources can be processed to determine a third frequency-domain resource where all are located in the subband. Furthermore, when performing repeated transmission in the second time-domain unit, using the third frequency-domain resource for repeated transmission ensures that the terminal can complete the repeated transmission smoothly.

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

[0037] In one embodiment, the first time-domain unit is Uplink slots including downlink subbands, Flexible slots including downlink subbands, Downlink slots including uplink subbands, Includes at least one of the flexible slots, including the uplink subband.

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

[0039] The first time-domain unit can be determined as needed, and includes, but is not limited to, the methods shown in some of the embodiments below.

[0040] In one embodiment, a network device can first set the transmission direction of a first time-domain unit, for example, a first transmission direction, through first information, which includes, but is not limited to, a Time Division Duplexing (TDD) UL-DL configuration and a Slot Format Indication (SFI). In this embodiment, the first information is carrier-level, meaning that the first information is applicable to all BWPs within the same carrier. Based on the first information, a terminal can determine whether the first time-domain unit is an uplink slot (first transmission direction is uplink) or a downlink slot (first transmission direction is downlink).

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

[0042] Since the second transmission direction is different from the first transmission direction, if the terminal determines, based on the second information, that the transmission direction in the first time-domain unit is the second transmission direction, then the terminal can determine that the first time-domain unit is the first time-domain unit. For example, if 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 if 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, a network device can first set the transmission direction of a first time-domain unit, for example, a first transmission direction, through the cell's TDD UL-DL configuration, where the cell's TDD UL-DL configuration is cell-level (carrier-level) and is the same for all BWPs of the same carrier. Based on the first information, a terminal can determine whether the first time-domain unit is an uplink slot (first transmission direction is uplink) or a downlink slot (first transmission direction is downlink).

[0044] In the subsequent communication process, network devices can adjust the transmission direction of terminals in a first time-domain unit through the TDD UL-DL configuration of a preset BWP pair. For example, a network device can instruct a terminal's transmission direction in a first time-domain unit to be the second transmission direction through the TDD UL-DL configuration of a preset BWP pair. The TDD UL-DL configuration of a preset BWP pair is at the BWP level and therefore may differ for each BWP.

[0045] In this case, the terminal can maintain two activated BWP pairs, one being a preset BWP pair and the other being a BWP pair other than the preset BWP pair, which can be called a normal BWP pair. The two BWP pairs can correspond to different TDD UL-DL configurations, and the terminal determines 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 described above, 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 downlink BWP in the preset BWP pair, and for communication in units 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 downlink BWP in the normal BWP pair.

[0047] Network devices can also specify a preset BWP pair within at least one BWP pair by transmitting instructional information. Since network devices can send BWP-level TDD UL-DL configurations to terminals, each BWP pair corresponds to a TDD UL-DL configuration. Therefore, network devices must notify terminals of a preset BWP pair from among multiple BWP pairs through instructional information, thereby allowing the terminal to determine a second transmission direction according to the TDD UL-DL configuration of the preset BWP pair. A preset BWP pair may also be called a reference BWP pair or an SBFD BWP pair.

[0048] Since the second transmission direction is different from the first transmission direction, if the terminal determines, based on the second information, that the transmission direction in the first time-domain unit is the second transmission direction, then the terminal can determine that the first time-domain unit is the first time-domain unit. For example, if 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 if 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, full-duplex operation can be defined to be performed on a semi-static time-domain resource (e.g., a symbol, a slot) or a time-domain resource indicated by an SFI in the TDD frequency band, so that a slot included in the time-domain resource or a slot on which the time-domain resource is located can be used as a first time-domain unit.

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

[0051] Method 1: In a downlink time-domain resource, the network device configures the terminal with either an UL subband or a DL subband. In the UL subband, the terminal can only perform uplink transmissions, and in the DL subband, the terminal can only perform uplink receptions. Method 2: In a downlink time-domain resource, the network device configures the terminal with either an UL subband or a DL subband. In the UL subband or DL ​​subband, the network device schedules a data channel or provides a reference signal. The terminal then decides whether to perform uplink or downlink communication according to the instruction.

[0052] The processing of the first frequency domain resource primarily involves several methods, including frequency domain offsetting, interleaving, and frequency hopping (FH). These methods are illustrated by several examples below.

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

[0054] In step S201, if the repeated transmission is a non-interleaved downlink transmission, the first frequency domain resource is offset in the frequency domain so as to be offset to the downlink subband of the first time domain unit, and 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, an interleaving operation is performed in the downlink subband of the first time-domain unit to interleave the first frequency-domain resource into the downlink subband of the first time-domain unit, and the interleaved first frequency-domain resource becomes 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 type0 Random Access (RA) Physical Downlink Shared Channel (PDSCH) or type1 RA PDSCH w / o interleaving, the first frequency domain resources can be offset if all of the first frequency domain resources are located in the active bandwidth portion but not all of them are located in the downlink subband. By performing the offset in the frequency domain, all of the first frequency domain resources within the first time domain unit can be offset to the downlink subband and become second frequency domain resources.

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

[0057] In one embodiment, with respect to an uplink slot or flexible slot including a downlink subband, if the recurring transmission is an interleaved downlink transmission, for example, type1 RA PDSCH w / interleaving (interleaving is on), and all of the first frequency domain resources are located in the active bandwidth portion, but not all are located in the downlink subband, then an interleaving operation can be performed within the downlink subband of the first time domain unit. By performing the interleaving operation, all of the first frequency domain resources within the first time domain unit can be interleaved into the downlink subband to become second frequency domain resources.

[0058] Figure 3 is a schematic flowchart of yet another repeatable transmission method according to an embodiment of the present disclosure. As shown in Figure 3, the first time-domain unit includes a downlink slot or flexible slot including an uplink subband, and processing the first frequency-domain resources to determine a second frequency-domain resource, all of which are located in the subband 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, the first frequency domain resource is offset in the frequency domain so as to be offset to the uplink subband of the first time domain unit, and the offset first frequency domain resource is the second frequency domain resource, and / or In step S302, if the repeated transmission is an uplink transmission with frequency hopping, a frequency hopping operation is performed 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) w / o FP (non-frequency-hopping), the first frequency domain resources can be offset if all of the first frequency domain resources are located in the active bandwidth portion, but not all of them are located in the uplink subband. By performing the offset in the frequency domain, all of the first frequency domain resources within the first time domain unit can be offset to the downlink subband and become second frequency domain resources.

[0061] In one embodiment, for a downlink slot or flexible slot including an uplink subband, if the recurring transmission is a frequency-hopping uplink transmission, for example, type1 RA PUSCH w / FP (frequency hopping is turned on), and all of the first frequency domain resources are located in the active bandwidth portion but not all are located in the uplink subband, then a frequency hopping operation can be performed within the downlink subband of the first time domain unit. By performing the frequency hopping operation, all of the first frequency domain resources within the first time domain unit can be frequency-hopped to the downlink subband and become second frequency domain resources.

[0062] Figure 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 a downlink slot, F represents a flexible slot, and U represents an uplink slot. The slot structure can be determined according to the Cell Specific tdd-UL-DL-Configuration Common.

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

[0065] For example, if the first frequency domain resources used for repeated transmission are all located in the active bandwidth portion, but not all in the uplink subband, and the repeated transmission is a non-frequency-hopping uplink transmission, then the first frequency domain resources can be offset on the first time domain unit, and the first frequency domain resources can be offset to the uplink subband to obtain a second frequency domain resource. The frequency domain ranges of the second and first frequency domain resources may be the same, but their starting positions may differ.

[0066] Furthermore, the terminal continues to perform repeated transmissions in the first frequency domain resource in the third and fourth slots, and in the second slot, it performs repeated transmissions in the second frequency domain resource.

[0067] Figure 5 is a schematic flowchart of yet another repeating transmission method according to an embodiment of the present disclosure. As shown in Figure 5, processing the first frequency domain resources to determine a third frequency domain resource, 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, the first frequency domain resource is offset in the frequency domain so as to be offset to the downlink subband of the second time domain unit, and 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, an interleaving operation is performed 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 becomes the third frequency-domain resource.

[0069] In one embodiment, for a second time-domain unit, if the repetitive transmission is a non-interleaved downlink transmission, such as type0 RA PDSCH or type1 RA PDSCH w / o interleaving, the first frequency-domain resources can be offset if all of the first frequency-domain resources are located in the downlink subband, but not all of them are located in the active bandwidth portion. By performing the offset in the frequency domain, all of the first frequency-domain resources within the first time-domain unit can be offset to the active bandwidth portion and become third frequency-domain resources.

[0070] In one embodiment, with respect to a second time-domain unit, if the repetitive transmission is an interleaved downlink transmission, for example, type1 RA PDSCH w / interleaving, and all of the first frequency-domain resources are located in the downlink subband, but not all are located in the active bandwidth portion, then an interleaving operation can be performed within the active bandwidth portion of the first time-domain unit. By performing the interleaving operation, all of the first frequency-domain resources within the first time-domain unit can be interleaved into the active bandwidth portion to become a third frequency-domain resource.

[0071] Figure 6 is a schematic flowchart of yet another repeating transmission method according to an embodiment of the present disclosure. As shown in Figure 6, processing the first frequency domain resources to determine a third frequency domain resource, 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, the first frequency domain resource is offset in the frequency domain so as to be offset in the uplink bandwidth portion of the second time domain unit, and the offset first frequency domain resource is the third frequency domain resource, and / or In step S602, if the repeated transmission is an uplink transmission with frequency hopping, a frequency hopping operation is performed 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 a second time-domain unit, if the repetitive transmission is a non-frequency-hopping uplink transmission, such as PUSCH w / o FP, then the first frequency-domain resources can be offset if all of the first frequency-domain resources are located in the uplink subband, but not all of them are located in the active bandwidth portion. By performing the offset in the frequency domain, all of the first frequency-domain resources within the first time-domain unit can be offset to the active bandwidth portion and become third frequency-domain resources.

[0074] In one embodiment, for a second time-domain unit, if the repetitive transmission is a frequency-hopping uplink transmission, for example, type1 RA PUSCH w / FP, and all of the first frequency-domain resources are located in the uplink subband but not all are located in the active bandwidth portion, then a frequency-hopping operation can be performed within the active bandwidth portion of the first time-domain unit. By performing the frequency-hopping operation, all of the first frequency-domain resources within the first time-domain unit can be frequency-hopped to the downlink subband to become third frequency-domain resources.

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

[0076] As shown in Figure 7, 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.

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

[0078] For example, if the first frequency domain resources used for repeated transmission are all located within the uplink subband, but not all are located in the active bandwidth portion, and if the repeated transmission is a non-frequency-hopping uplink transmission, the first frequency domain resources can be offset within a second time-domain unit, and a third frequency domain resource can be obtained by offsetting the first frequency domain resources into the active bandwidth portion. The frequency domain ranges of the third frequency domain resource and the first frequency domain resource may be the same, but their starting positions may differ.

[0079] Furthermore, the terminal repeatedly performs transmissions on the third frequency domain resource in the third and fourth slots, while still repeatedly performing transmissions on the first frequency domain resource in the second slot.

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

[0081] As shown in Figure 8, 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.

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

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

[0084] Figure 9 is a schematic flowchart of a repeating transmission method according to an embodiment of the present disclosure. The repeating transmission method shown in this embodiment can be performed by a network device, which can communicate with a terminal, and the network device includes, but is not limited to, base stations in a communication system such as 4G base stations, 5G base stations, and 6G base stations, and the terminal includes, but is not limited to, communication devices such as mobile phones, tablet computers, wearable devices, sensors, and Internet of Things devices.

[0085] As shown in Figure 9, the repeated transmission method may include the following steps.

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

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

[0088] In step S903, if not all of the first frequency domain resources for repeated transmission in the first time domain unit are located in the subband of the first time domain unit, the first frequency domain resources are processed to determine the second frequency domain resources which are all located in the subband of the first time domain unit, repeated transmission is performed with the terminal using the second frequency domain resources in the first time domain unit, and / or In step S904, if not all of the first frequency domain resources for repeated transmission in the second time domain unit are located in the active bandwidth portion of the second time domain unit, the first frequency domain resources are processed to determine a third frequency domain resource in which all are located in the active bandwidth portion of the second time domain unit, and repeated transmission is performed with the terminal using the third frequency domain resource in the second time domain unit.

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

[0090] In one embodiment, each repetitive transmission may be placed in a different slot, and the slot includes 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 can repeatedly perform transmissions in the active bandwidth portion (active BWP) according to the network device's scheduling.

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

[0093] If the repetitive transmission includes both a first time-domain unit and a second time-domain unit, several technical issues may arise. Note that the first time-domain unit is used to represent one type of slot, not one slot, and similarly, the second time-domain unit is also used to represent one type of slot, not one slot.

[0094] The active bandwidth portion corresponding to each slot may be the same, but since the subband is composed only of the first time-domain unit, the following cases may occur.

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

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

[0097] In the case described in Case 1 above, in the first time-domain unit, the terminal repeatedly transmits in the subband according to the network device's scheduling. Therefore, if all of the first frequency-domain resources for repeated transmission are located in the active bandwidth portion, but not all are located in the subband, the first frequency-domain resources can be processed to determine a second frequency-domain resource where all are located in the subband. Furthermore, when performing repeated transmission in the first time-domain unit, using the second frequency-domain resources for repeated transmission ensures that the terminal can complete the repeated transmission smoothly.

[0098] In the case of Case 2 described above, in the second time-domain unit, since the terminal repeatedly transmits in the active bandwidth portion according to the network device's scheduling, if all of the first frequency-domain resources for repeated transmission are located in the subband but not all are located in the bandwidth portion, the first frequency-domain resources can be processed to determine a third frequency-domain resource where all are located in the subband. Furthermore, when performing repeated transmission in the second time-domain unit, using the third frequency-domain resource for repeated transmission ensures that the terminal can complete the repeated transmission smoothly.

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

[0100] In one embodiment, the first time-domain unit is Uplink slots including downlink subbands, Flexible slots including downlink subbands, Downlink slots including uplink subbands, Includes at least one of the flexible slots, including the uplink subband.

[0101] For example, in a downlink slot that includes an uplink subband, the terminal can achieve full-duplex communication by performing uplink communication in the uplink subband and downlink communication in frequency domain resources other than the uplink subband. For example, in a flexible slot that includes an uplink subband, the terminal can achieve full-duplex communication by performing uplink communication in the uplink subband and downlink communication in frequency domain resources other than the uplink subband. For example, in an uplink slot that includes a downlink subband, the terminal can achieve full-duplex communication by performing downlink communication in the downlink subband and uplink communication in frequency domain resources other than the downlink subband. For example, in a flexible slot that includes a downlink subband, the terminal can achieve full-duplex communication by performing downlink communication in the downlink subband and 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 flexible slot that includes a downlink subband, and the first frequency-domain resources are processed to determine a second frequency-domain resource that is all located in the subband of the first time-domain unit. If the repeated transmission is a non-interleaved downlink transmission, the first frequency domain resource is offset in the frequency domain so as to be offset to the downlink subband of the first time domain unit, and the offset first frequency domain resource is the second frequency domain resource, and / or If the repeated transmission is an interleaved downlink transmission, the method includes performing an interleaving operation in the downlink subband of the first time-domain unit to interleave the first frequency-domain resource into the downlink subband of the first time-domain unit, wherein the interleaved first frequency-domain resource is the second frequency-domain resource.

[0103] In one embodiment, for an uplink slot or flexible slot including a downlink subband, if the repetitive transmission is a non-interleaved downlink transmission, such as type0 RA PDSCH, type1 RA PDSCH w / o interleaving, then the first frequency domain resources can be offset if all of the first frequency domain resources are located in the active bandwidth portion, but not all of them are located in the downlink subband. By performing the offset in the frequency domain, all of the first frequency domain resources within the first time domain unit can be offset to the downlink subband and become second frequency domain resources.

[0104] In one embodiment, with respect to an uplink slot or flexible slot including a downlink subband, if the recurring transmission is an interleaved downlink transmission, for example, type1 RA PDSCH w / interleaving (interleaving is on), and all of the first frequency domain resources are located in the active bandwidth portion, but not all are located in the downlink subband, then an interleaving operation can be performed within the downlink subband of the first time domain unit. By performing the interleaving operation, all of the first frequency domain resources within the first time domain unit can be interleaved into the downlink subband to become second frequency domain resources.

[0105] In one embodiment, the first time-domain unit includes a downlink slot or flexible slot that includes an uplink subband, and the first frequency-domain resources are processed to determine a second frequency-domain resource that is all located in the subband of the first time-domain unit. If the repeated transmission is a non-frequency-hopping uplink transmission, the first frequency domain resource is offset in the frequency domain so as to be offset to the uplink subband of the first time domain unit, and the offset first frequency domain resource is the second frequency domain resource, and / or If the repeated transmission is an uplink transmission with frequency hopping, the method includes performing 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, wherein the interleaved first frequency-domain resource is the second frequency-domain resource.

[0106] In one embodiment, for a downlink slot or flexible slot including an uplink subband, if the repetitive transmission is a non-frequency-hopping uplink transmission, such as PUSCH w / o FP, the first frequency domain resources can be offset if all of the first frequency domain resources are located in the active bandwidth portion, but not all of them are located in the uplink subband. By performing the offset in the frequency domain, all of the first frequency domain resources within the first time domain unit can be offset to the downlink subband and become second frequency domain resources.

[0107] In one embodiment, with respect to a downlink slot or flexible slot including an uplink subband, if the repeated transmission is a frequency-hopping uplink transmission, for example, type1 RA PUSCH w / FP, and all of the first frequency domain resources are located in the active bandwidth portion but not all are located in the uplink subband, then a frequency-hopping operation can be performed within the downlink subband of the first time domain unit. By performing the frequency-hopping operation, all of the first frequency domain resources within the first time domain unit can be frequency-hopped to the downlink subband to become second frequency domain resources.

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

[0109] In one embodiment, for a second time-domain unit, if the repetitive transmission is a non-interleaved downlink transmission, such as type0 RA PDSCH or type1 RA PDSCH w / o interleaving, the first frequency-domain resources can be offset if all of the first frequency-domain resources are located in the downlink subband, but not all of them are located in the active bandwidth portion. By performing the offset in the frequency domain, all of the first frequency-domain resources within the first time-domain unit can be offset to the active bandwidth portion and become third frequency-domain resources.

[0110] In one embodiment, with respect to a second time-domain unit, if the repetitive transmission is an interleaved downlink transmission, for example, type1 RA PDSCH w / interleaving, and all of the first frequency-domain resources are located in the downlink subband, but not all are located in the active bandwidth portion, then an interleaving operation can be performed within the active bandwidth portion of the first time-domain unit. By performing the interleaving operation, all of the first frequency-domain resources within the first time-domain unit can be interleaved into the active bandwidth portion to become a third frequency-domain resource.

[0111] In one embodiment, processing the first frequency domain resources to determine a third frequency domain resource, all of which are located in the active bandwidth portion of the second time domain unit, If the repeated transmission is a non-frequency-hopping uplink transmission, the first frequency domain resource is offset in the frequency domain so as to be offset in the uplink bandwidth portion of the second time domain unit, and the offset first frequency domain resource is the third frequency domain resource, and / or If the repeated transmission is an uplink transmission with frequency hopping, the frequency hopping operation is performed 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.

[0112] In one embodiment, for a second time-domain unit, if the repetitive transmission is a non-frequency-hopping uplink transmission, such as PUSCH w / o FP, then the first frequency-domain resources can be offset if all of the first frequency-domain resources are located in the uplink subband, but not all of them are located in the active bandwidth portion. By performing the offset in the frequency domain, all of the first frequency-domain resources within the first time-domain unit can be offset to the active bandwidth portion and become third frequency-domain resources.

[0113] In one embodiment, for a second time-domain unit, if the repetitive transmission is a frequency-hopping uplink transmission, for example, type1 RA PUSCH w / FP, and all of the first frequency-domain resources are located in the uplink subband but not all are located in the active bandwidth portion, then a frequency-hopping operation can be performed within the active bandwidth portion of the first time-domain unit. By performing the frequency-hopping operation, all of the first frequency-domain resources within the first time-domain unit can be frequency-hopped to the downlink subband to become third frequency-domain resources.
