Description

Technical Field

[0001] Embodiments of the present disclosure relate generally to the field of telecommunications, and more particularly to methods, devices, and computer storage media for communications. Background Art

[0002] Traditionally, a user equipment (UE) performs only half-duplex operation in communication with a network. That is, if a half-duplex time division duplex (TDD) mode is configured for a UE, the UE is configured to perform only one of an uplink (UL) transmission and a downlink (DL) transmission with the network for a bandwidth part (BWP) at a time.

[0003] In New Radio (NR) technology, it aims to deploy a sub-band non-overlapping full-duplex scheme in unpaired spectrum. That is, UEs can be configured with symbols / slots that have both DL resources and UL resources, and the network equipment (e.g., gNB) can schedule DL transmissions for some UEs and UL transmissions for other UEs in the same symbol / slot. However, the details of this scheme are not yet complete and need further development. Summary of the invention

[0030] The term "network equipment" refers to equipment that is capable of providing or hosting a cell or coverage area in which a terminal device can communicate. Examples of network equipment include, but are not limited to, Node B (NodeB or NB), evolved NodeB (eNodeB or eNB), next generation NodeB (gNB), transmission reception point (TRP), remote radio unit (RRU), radio head (RH), remote radio head (RRH), IAB node, low power node (such as femto node, pico node), reconfigurable intelligent surface (RIS), network controlled repeater, etc.

[0034] The embodiments of the present disclosure may be executed in a test device, such as a signal generator, a signal analyzer, a spectrum analyzer, a network analyzer, a test terminal device, a test network device, and a channel emulator.

[0035] Embodiments of the present disclosure may be performed according to any generation of communication protocols currently known or to be developed in the future. Examples of communication protocols include, but are not limited to, first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) communication protocols, 5.5G, 5G advanced networks, or sixth generation (6G) networks.

[0036] In one embodiment, the terminal device may be connected to a first network device and a second network device. One of the first network device and the second network device may be a primary node, and the other may be a secondary node. The first network device and the second network device may use different radio access technologies (RATs). In one embodiment, the first network device may be a first RAT device, and the second network device may be a second RAT device. In one embodiment, the first RAT device is an eNB, and the second RAT device is a gNB. Information related to different RATs may be sent to the terminal device from at least one of the first network device or the second network device. In one embodiment, the first information may be sent from the first network device to the terminal device, and the second information may be sent directly or via the first network device from the second network device to the terminal device. In one embodiment, information related to the configuration of the terminal device configured by the second network device may be sent from the second network device via the first network device. Information related to the reconfiguration of the terminal device configured by the second network device may be sent directly or via the first network device from the second network device to the terminal device.

[0037] As used herein, the singular forms 'a', 'an' and 'the' shall also include the plural forms unless the context clearly indicates otherwise. The term 'including' and its variations shall be understood as open terms, meaning 'including but not limited to'. The term 'based on' shall be understood as 'based at least in part on'. The terms 'one embodiment' and 'embodiment' shall be understood as 'at least one embodiment'. The term 'another embodiment' shall be understood as 'at least one other embodiment'. The terms 'first', 'second', etc. may refer to different or the same objects. Other explicit and implicit definitions may be included below.

[0038] In some examples, values, processes, or devices are referred to as 'best', 'lowest', 'highest', 'minimum', 'maximum', etc. It should be understood that such descriptions are intended to indicate that one can choose among many functional alternatives that can be used, and that such a choice is not necessarily better, lesser, higher, or otherwise preferred over other choices.

[0039] In the context of the present application, the term "opportunity" refers to any of the following: 1) time domain resources and frequency domain resources allocated, configured, or authorized for data transmission, for example, the time domain resources may include: one or more time slots, one or more mini-time slots, or one or more symbols; 2) one or more time slots in which DL allocation, UL authorization, or sidelink authorization occurs; 3) one or more symbols in which DL allocation, UL authorization, or sidelink authorization occurs.

[0040] In the context of this application, the term "SBFD symbol / slot" refers to a symbol / slot with a subband that a network device (e.g., gNB) will use for SBFD operation. For SBFD operation within a TDD carrier, an SBFD subband includes: 1 resource block (RB), or a set of consecutive RBs in the same transmission direction. In the context of this application, the term "SBFD-capable UE" refers to a UE that is aware of the time and frequency domain locations of the SBFD subband.

[0041] In the context of this application, the term "symbol" refers to an orthogonal frequency division multiplexing (OFDM) symbol or a discrete Fourier transform spread OFDM (DFT-s-OFDM) symbol. The term "time slot" includes a plurality of consecutive symbols, such as 14 symbols or 12 symbols. The term "mini slot" includes one or more consecutive symbols and has fewer symbols than a time slot, such as 1, 2, 4, or 7 symbols.

[0042] Typically, in conventional half-duplex TDD mode, symbols / slots in a TDD carrier can only be used for DL ​​transmission or UL transmission. The UE determines the dynamic scheduling transmission or high-level configuration in the symbol / slot based on the TDD configuration of the carrier, for example, configured by tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. In other words, the symbol / slot on the cell is associated with only one transmission direction (e.g., DL or UL). Symbols / slots associated with one transmission direction are called half-duplex symbols / slots, i.e., TDD symbols / slots. For example, DL symbols / slots are associated with only DL transmission directions; UL symbols / slots are associated with only UL transmission directions; and flexible symbols / slots are DL or UL transmission directions. In TDD mode, a network device (e.g., a gNB) can schedule DL transmissions for UEs in the cell only on DL symbols / slots and / or flexible symbols / slots, and schedule UL transmissions for UEs in the cell only on UL symbols / slots and / or flexible symbols / slots.

[0043] However, in the subband non-overlapping full-duplex scheme, in order to increase more opportunities for UL transmission to reduce latency and improve coverage, the network device (e.g., gNB) supports simultaneous UL reception and DL transmission on the SBFD symbol / slot on the TDD carrier, while the UE still operates in half-duplex mode. Under this scheme, the BWP can be divided into multiple non-overlapping subbands. A guard band can be configured between two subbands in the BWP. The UE can be configured to perform UL transmission on one of the multiple subbands in the symbol / slot and perform DL transmission on another subband in the multiple subbands in another symbol / slot. That is, the UE can perform transmission or reception in subband full-duplex mode. This scheme can achieve enhanced UL coverage, reduced latency, improved system capacity, and improved configuration flexibility for NRTDD operation in unpaired spectrum.

[0044] A possible subband non-overlapping full-duplex scheme is that the UL subband used for UL transmission is located on a DL symbol or flexible symbol configured by tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated. When a subband non-overlapping full-duplex scheme is deployed in an unpaired spectrum, the symbol / slot on the cell can be associated with one transmission direction (ie, DL or UL) or two transmission directions (ie, DL and UL). The symbol / slot associated with two transmission directions is called a subband full-duplex (SBFD) symbol / slot. The network device can schedule DL transmission for UEs in the cell on DL TDD symbols / slots, flexible TDD symbols / slots, and SBFD symbols / slots, and can schedule UL transmission for UEs in the cell on UL TDD symbols / slots, flexible TDD symbols / slots, and SBFD symbols / slots.

[0045] The SBFD scheme may have an impact on both DL transmissions and UL transmissions. Therefore, the details on how to handle DL transmissions or UL transmissions in the SBFD scheme may require further development or improvement. For example, if a transmission configured by a higher layer spans TDD symbols / slots (e.g., UL TDD symbols / slots, and flexible TDD symbols / slots for UL transmissions; and DL TDD symbols / slots, and flexible TDD symbols / slots for DL ​​transmissions) and SBFD symbols / slots, it is unclear how to handle transmissions with variable frequency domain resources.

[0046] In view of this, the embodiments of the present disclosure provide a solution to the above and other potential problems. The principle and implementation of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0047] Figure 11 illustrates a schematic diagram of an example communication network 100 in which some embodiments of the present disclosure may be implemented. Figure 1 As shown in , the communication network 100 may include a terminal device 110 and a network device 120. In some embodiments, the network device 120 may provide a service cell (also referred to herein as a cell), and the terminal device 110 may be located in the cell and may be served by the network device 120. It should be understood that Figure 1 The number of devices or cells given in the example is for illustrative purposes and does not impose any limitation on the present disclosure. The communication network 100 may include any suitable number of network devices and / or terminal devices and / or cells suitable for implementing the present disclosure.

[0048] like Figure 1 As shown in , the terminal device 110 can communicate with the network device 120 via a channel such as a wireless communication channel. The communication in the communication network 100 can meet any suitable standard, including but not limited to Global System for Mobile Communications (GSM), Long Term Evolution (LTE), LTE Evolution, Advanced LTE (LTE-A), New Radio (NR), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), GSM EDGE Radio Access Network (GERAN), Machine Type Communication (MTC), etc. The embodiments of the present disclosure can be performed according to any generation of communication protocols currently known or to be developed in the future. Examples of communication protocols include but are not limited to first generation (1G), second generation (2G), 2.5G, 2.75G, third generation (3G), fourth generation (4G), 4.5G, fifth generation (5G) communication protocols, 5.5G, 5G advanced networks, or sixth generation (6G) networks.

[0049] Communication in a direction from the terminal device 110 toward the network device 120 is called UL communication, and communication in an opposite direction from the network device 120 toward the terminal device 110 is called DL communication. Wireless communication channels may include a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), a physical random access channel (PRACH), a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), and a physical broadcast channel (PBCH).

[0050] In some embodiments, the terminal device 110 may send UL data to the network device 120 via a UL data channel transmission. For example, the UL data channel transmission may be a physical uplink shared channel (PUSCH) transmission. Of course, any other suitable form is also feasible.

[0051] In some embodiments, the terminal device 110 may receive DL data from the network device 120 via a DL data channel transmission. For example, the DL data channel transmission may be a physical downlink shared channel (PDSCH) transmission. Of course, any other suitable form is also feasible.

[0052] In some embodiments, the terminal device 110 may receive downlink control information (DCI) from the network device 120 via a DL control channel transmission. For example, the DL control channel transmission may be a PDCCH transmission. Of course, any other suitable form is also feasible.

[0053] In some embodiments, the terminal device 110 may send uplink control information (UCI) to the network device 120 via a UL control channel transmission. For example, the UL control channel transmission may be a PUCCH transmission. Of course, any other suitable form is also feasible.

[0054] Figure 2 A schematic diagram 200 illustrating an example scenario of multiple transmissions in SBFD communications in a related solution is illustrated. Figure 2 As shown in , time slots #0 to #4, and time slots #8 to #9 are half-duplex TDD time slots, and time slots #5 to #7 are sub-band full-duplex time slots. It should be understood that Figure 2 The time interval in may be implemented as a symbol, a mini-slot, or a time slot. For example, a time slot may include: a half-duplex TDD symbol, and / or a sub-band full-duplex symbol.

[0055] In one embodiment, the network device 120 may schedule four PUSCH transmissions for the terminal device 110. For example, the terminal device 110 may receive DCI #1 from the network device 120 for scheduling four PUSCH transmissions (i.e., PUSCH #1-PUSCH #4) on time slots #3 to #6. As another example, the terminal device 110 may receive DCI #2 from the network device 120 for scheduling four PUSCH transmissions (i.e., PUSCH #5-PUSCH #8) on time slots #3 to #6. Since time slots #3 and #4 are configured as half-duplex DL time slots and flexible symbols / time slots, the terminal device 110 may send PUSCH #1-PUSCH #2 or PUSCH #5-PUSCH #6. However, since symbols / time slots #5 and #6 are configured as SBFD symbols / time slots, the SBFD symbols / time slots may be configured with DL resources and UL resources in the BWP. In the case where PUSCH#7 and PUSCH#8 overlap with the DL subband in the SBFD symbol / time slot, the terminal device 110 cannot perform UL transmission of PUSCH#7 and PUSCH#8. In other words, since the frequency domain resources are variable, the terminal device 110 cannot determine how to handle multiple transmissions on both TDD symbols / time slots and SBFD symbols / time slots.

[0056] In view of this, an embodiment of the present disclosure provides a solution for determining resource allocation to support SBFD operation. Figures 3 to 5C Describe the solution in detail.

[0057] Figure 3 A schematic diagram illustrating a communication process 300 for multiple transmissions in SBFD communication according to some embodiments of the present disclosure is illustrated. For discussion purposes, reference will be made to Figure 1 Describe process 300. Process 300 may involve Figure 1 The terminal device 110 and the network device 120 shown. It should be understood that Figure 3 The steps and order of steps in the embodiment are for illustration only and are not intended to be limiting. For example, the order of the steps may be changed. Some steps may be omitted, or any other suitable additional steps may be added.

[0058] like Figure 3As shown in , the network device 120 sends (314) to the terminal device 110 an indication 316 of a transmission set to be sent or received by the terminal device 110 within a time interval set. The terminal device 110 receives (318) the indication 316 of the transmission set. The transmissions in the transmission set are indicated as being sent or received by the terminal device 110 within the time interval set in the time interval set. The transmission set may include a UL transmission set to be sent by the terminal device 110, or may include a DL transmission set to be received by the terminal device 110. In some examples, the transmission set may include multiple transmissions scheduled by the DCI. In some examples, the transmission set may include multiple configured grant (CG) transmissions. In some examples, the transmission set may include multiple repetitions of the transmission. Based on the preconfigured resource allocation, the terminal device 110 may determine the time and frequency resources indicated for each transmission in the transmission set.

[0059] After determining (326) that the time intervals for transmission include time intervals associated with the sub-band full-duplex mode, the terminal device 110 performs operations (328) related to sending or receiving transmissions. Embodiments of the present application define explicit UE behaviors for SBFD-capable UEs to send or receive multiple transmissions on UL unique symbols / time slots and SBFD symbols / time slots.

[0060] In some embodiments, the network device 120 may send (302) a TDD configuration 304, such as tdd-UL-DL-ConfigurationCommon, and / or tdd-UL-DL-ConfigurationDedicated, to the terminal device 110. The terminal device 110 receives (306) the TDD configuration 304 and determines the direction of transition over a time interval (e.g., symbol / time slot) accordingly. The terminal device 110 considers symbols in symbols / time slots indicated as downlink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated as available for reception, and considers symbols in symbols / time slots indicated as uplink by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated as available for transmission. The network device 120 may send (308) an SBFD configuration 310, such as time and frequency resources for a UL subband, to the terminal device 110. Terminal device 110 receives 312 SBFD configuration 310 and therefore knows the configuration of the SBFD symbols / slots.Based on the TDD configuration and the SBFD configuration, terminal device 110 may determine if there is an overlap between a scheduled transmission and a SBFD symbol / slot.

[0061] Will combine Figure 4A-4E Some example embodiments are described with respect to performing operations related to sending or receiving transmissions. Figure 4A-4E The transmission and reception of multiple PUSCHs scheduled by DCI in a DL symbol / time slot with a UL subband are shown, but the concepts of these embodiments can also be applied to other UL transmissions, such as PUCCH / PRACH / SRS, DL transmissions of UL symbols / time slots with DL subbands. In addition, the concepts of these embodiments are not limited to dynamic grant transmissions, but also apply to CG transmissions, transmissions of dynamic grant (DG) repetition opportunities, and transmissions of CG repetition opportunities. It should be understood that the number and period of scheduled transmissions are given for illustrative purposes and do not impose any limitations on the contents of the present disclosure.

[0062] Example 1

[0063] In this embodiment, the terminal device 110 can determine how to send multiple transmissions that overlap with SBFD symbols / time slots based on the frequency resource allocation for these transmissions. For example, if the allocated frequency resources for UL transmission are located in the UL subband in the SBFD symbol / time slot, the SBFD symbol / time slot will be regarded as a valid / UL symbol / time slot for UL transmission; if the allocated frequency resources for UL transmission are located in the DL subband or guard band in the SBFD symbol / time slot, the SBFD symbol / time slot will be regarded as an invalid / DL symbol / time slot for UL transmission.

[0064] In some embodiments, the terminal device 110 may determine that the time interval is valid for sending or receiving a transmission if the frequency resources allocated for transmission are within a first subband having a first direction in the time interval, where the first direction is the same as the direction of transmission between the terminal device 110 and the network device 120. The terminal device 110 may determine that the time interval is invalid for sending or receiving a transmission if the frequency resources overlap with a second subband having a second direction, or overlap with a guard band between the first subband and the second subband, where the second direction is different from the first direction. For example, a UL transmission indicated as being sent on a UL subband of a SBFD symbol / timeslot may be sent by the terminal device on the SBFD symbol / timeslot, while a UL transmission indicated as being sent on a DL subband or guard band of a SBFD symbol / timeslot will not be sent on the SBFD symbol / timeslot.

[0065] To illustrate, we will Figure 4A and Figure 4B An example is described in . Figure 4A and Figure 4B Schematic diagrams 400A and 400B are illustrated illustrating example scenarios of multiple transmissions in SBFD communications according to embodiments of the present disclosure. Figure 4AAs shown in , the BWP in the TDD symbol / slot is the same as the BWP in the SBFD symbol / slot. The BWP may include only one or more subbands. The terminal device determines that the frequency domain resource allocation for PUSCH transmission on the UL BWP in the TDD symbol is the same as the frequency domain resource allocation for PUSCH transmission on the UL subband in the SBFD symbol, that is, the frequency resource allocation indicated in the scheduling DCI applies to both UL unique symbols and SBFD symbols. Assume that PUSCH#1-PUSCH#4 scheduled by DCI#1 are indicated to be transmitted on symbols / slots with different duplex types, for example, UL unique symbols / slots (i.e., symbols / slots #3 and #4), and SBFD symbols / slots (i.e., symbols / slots #5 and #6). The frequency resources allocated for PUSCH#3 and PUSCH#4 are located within the UL subband in the SBFD symbols / slots #5 and #6, so SBFD symbols / slots #5 and #6 will be regarded as valid symbols for PUSCH transmission. As Figure 4A As shown in , the terminal device 110 can send PUSCH#1-PUSCH#4 to the network device 120 at symbol / time slot #1 to symbol / time slot #4 respectively.

[0066] Assume that the four PUSCHs scheduled by DCI #2 will be indicated as being transmitted on symbols / slots with different duplex types, for example, UL-only symbols / slots (i.e., symbols / slots #3 and #4) and SBFD symbols / slots (i.e., symbols / slots #5 and #6). The frequency resources accidentally allocated for the third and fourth PUSCHs are located in the DL subband in SBFD symbols / slots #5 and #6, so SBFD symbols / slots #5 and #6 will be regarded as invalid symbols for PUSCH transmission. Figure 4A As shown in , the terminal device 110 can send PUSCH#5-PUSCH#6 to the network device 120 only at symbols / time slots #3 and #4, respectively, and cancel sending the third PUSCH and the fourth PUSCH.

[0067] Alternatively, the invalid symbols / time slots may be skipped and the transmission originally allocated to the invalid symbols / time slots may be postponed to the subsequent valid symbols / time slots. Figure 4B As shown in , the terminal device 110 can send PUSCH#5-PUSCH#6 to the network device 120 at symbols / time slots #3 and #4, respectively; skip invalid symbols / time slots #5 to #7; and postpone sending PUSCH#7 and PUSCH#8 at symbols / time slots #8 and #9, respectively.

[0068] The concepts of these embodiments can also be applied to CG transmissions. For example, a CG PUSCH of a CG configuration can be sent on both TDD time slots and SBFD time slots. In the case where the CG PUSCH opportunity is located in a SBFD symbol / time slot, the terminal device 110 determines whether the SBFD symbol / time slot is valid for sending the CG PUSCH based on the frequency resource allocation of the CG PUSCH. In this embodiment, the BWP in the TDD symbol / time slot is the same as the BWP in the SBFD symbol / time slot. The BWP may include one or more subbands. The terminal device determines that the frequency domain resource allocation for the CG PUSCH transmission on the UL BWP in the TDD symbol is the same as the frequency domain resource allocation for the CG PUSCH transmission on the UL subband in the SBFD symbol, that is, the frequency resource allocation indicated in the activation DCI or configured by the RRC applies to both UL unique symbols and SBFD symbols. If the frequency resource allocation of CG PUSCH is located within the UL subband in the SBFD symbol / time slot, the SBFD symbol / time slot will be regarded as a valid / UL symbol / time slot for CG PUSCH transmission, and the terminal device 110 will send CG PUSCH in the SBFD symbol / time slot; otherwise, the SBFD symbol / time slot will be regarded as an invalid symbol / time slot for CG PUSCH transmission, and the terminal device 110 will cancel / skip the CG PUSCH transmission.

[0069] In some embodiments, a transmission set is a plurality of repetitions of a transmission. In some embodiments, when AvailableSlotCounting is enabled, invalid symbols / slots are skipped and not counted when determining the time domain resources for the repetitions of the transmission. In some embodiments, the terminal device 110 may cancel a transmission if the time resource of the transmission at least partially overlaps with a time interval that is invalid for sending or receiving the transmission. For example, if a portion of the UL transmission overlaps with a UL unique symbol / slot and another portion of the UL transmission overlaps with a DL subband and / or guard band of a SBFD symbol / slot, the UL transmission will not be sent.

[0070] In some alternative embodiments, if a first portion of the time resource for a transmission overlaps with a time interval that is invalid for sending or receiving a transmission, and a second portion of the time resource for the transmission overlaps with a valid time interval associated with the half-duplex mode, the terminal device 110 may send or receive a portion of the transmission that is within the valid time interval associated with the half-duplex mode. For example, if a portion of the UL transmission overlaps with a UL unique symbol / time slot, and another portion of the UL transmission overlaps with a DL subband and / or a guard band of a SBFD symbol / time slot, the terminal device 110 may send the portion of the UL transmission on the UL unique symbol / time slot by truncation or rate matching. The solutions of Embodiment 1 improve the spectrum efficiency and scheduling flexibility of network devices. In addition, these solutions may also achieve lower transmission delays.

[0071] Example 2

[0072] In this embodiment, the terminal device 110 may always determine the SBFD symbol / time slot as a valid symbol / time slot for transmission. For example, if the indicated or configured time domain resources for UL transmission are all located in the UL unique symbol / time slot and / or the UL subband of the SBFD symbol / time slot, the UL transmission will always be sent by the terminal device 110.

[0073] In some embodiments, the BWP in the TDD symbol / time slot is the same as the BWP in the SBFD symbol / time slot, and the same frequency resource allocation is determined for the BWP in the TDD symbol and the transmission on the subband in the SBFD symbol. The terminal device 110 expects that the allocated frequency resources for transmission will be limited to the corresponding subbands in all symbols / time slots. In other words, if the frequency resource overlaps with the second subband having a second direction, or overlaps with the guard band between the first subband and the second subband, the terminal device 110 can determine the transmission set as an error case, where the second direction is different from the first direction. For example, the terminal device 110 does not expect that the frequency resources allocated for UL transmission will be in the DL subband or guard band in the DL symbol / time slot or the SBFD symbol / time slot. This solution is simple for UE implementation.

[0074] In some alternative embodiments, the bandwidth part (BWP) available for the time interval includes at least: a first subband having a first direction in the time interval, and a second subband having a second direction, wherein the first direction is the same as the direction of transmission between the terminal device 110 and the network device 120, and the second direction is opposite to the first direction. In the context of the present application, the term "available BWP" refers to an active BWP or a configured BWP. The terminal device 110 can determine the frequency resource allocation for the transmission based on the reference BWP including the first subband. The terminal device 110 can send or receive transmissions in the time interval based on the frequency resource allocation. This solution can ensure that the indicated transmission on the SBFD symbol can be sent, thereby achieving lower transmission delay.

[0075] To illustrate, we will Figure 4C An example is described in . Figure 4C A schematic diagram 400C illustrating an example scenario of multiple transmissions in SBFD communications according to an embodiment of the present disclosure is illustrated. The BWP in the TDD symbol / slot is the same as the BWP in the SBFD symbol / slot, and the terminal device 110 can determine the reference BWP (short UL BWP) for SBFD symbols / slots #5 and #6 based on the BWP configuration and UL subband configuration of the TDD symbol / slot. The terminal device 110 can determine the frequency resources of PUSCH #3 and PUSCH #4 on the reference BWP in SBFD symbols / slots #5 and #6 in the same manner as for BWP switching, for example, using x MSB bits to provide frequency domain resource allocation when scheduling DCI. No actual BWP switching occurs. The reference BWP of the SBFD symbol / slot is only used to determine the frequency resources for transmissions on the SBFD symbol / slot.

[0076] In some alternative embodiments, the BWP may include only one subband. The terminal device 110 may determine the frequency resource allocation for transmission based on the BWP available for the time interval. The BWP includes: a first subband having a first direction in the time interval, wherein the first direction is the same as the direction of transmission between the terminal device 110 and the network device 120. The terminal device 110 may send or receive transmissions in the time interval based on the frequency resource allocation dedicated to the first subband in the SBFD symbol / time slot. In this embodiment, the BWP in the TDD symbol / time slot is different from the BWP in the SBFD symbol / time slot. The terminal device 110 may determine the frequency resources for transmission on the TDD symbol / time slot and the SBFD symbol / time slot in the same manner as for BWP switching. For example, when a scheduled first UL transmission is located in a UL unique symbol and a scheduled second UL transmission is located in a DL symbol having a UL subband, the terminal device determines the frequency resource allocation of the first UL transmission in the UL unique symbol based on the indicated frequency resource allocation of the first UL BWP configured for the TDD symbol in the DCI, and when the active UL BWP of the terminal device switches from the first UL BWP to the second UL BWP, the terminal device determines the frequency resource allocation of the second UL transmission in the UL subband in the SBFD symbol based on the indicated frequency resource allocation for the second UL BWP including the UL subband in the DCI. This solution can achieve lower latency and has less impact on the specification.

[0077] In some alternative embodiments, the terminal device 110 may receive information on frequency resource allocation for transmission from the network device 120. The information includes: a first frequency resource indicator for a time interval associated with a half-duplex mode, and a second frequency resource indicator for a time interval associated with a sub-band full-duplex mode. The terminal device 110 may determine the frequency resource allocation for transmission based on the second frequency resource indicator. The terminal device 110 may send or receive transmissions within a time interval based on the frequency resource allocation. In this embodiment, the BWP in a TDD symbol / time slot may be the same as or different from the BWP in a SBFD symbol / time slot. The terminal device 110 may receive two frequency resource indications corresponding to transmissions on a TDD symbol / time slot and a transmission on a SBFD symbol / time slot, respectively. The solution of embodiment 2 enables continuous transmission of multiple transmissions on a TDD symbol / time slot and / or a SBFD symbol / time slot, thereby achieving reduced delay and better coverage.

[0078] Example 3

[0079] In this embodiment, multiple transmissions may be sent on only one time interval, for example, only on TDD symbols / slots or only on SBFD symbols / slots. For example, if multiple PUSCHs scheduled by a single DCI are sent on half-duplex TDD symbols / slots, the SBFD symbols / slots will be skipped and not counted when determining the time domain resources for the multiple PUSCHs.

[0080] In some embodiments, the terminal device 110 may receive an indication from the network device 120 that a set of transmissions will be sent or received by the terminal device 110 in a time interval associated with the half-duplex mode or in a time interval associated with the sub-band full-duplex mode. If, based on the indication, the set of transmissions will be sent or received in a time interval associated with the sub-band full-duplex mode, the terminal device 110 may send or receive the transmission in the time interval. If, based on the indication, the set of transmissions will be sent or received in a time interval associated with the half-duplex mode, the terminal device 110 may skip the time interval associated with the sub-band full-duplex mode and postpone sending or receiving the transmission to a subsequent time interval associated with the half-duplex mode.

[0081] To illustrate, we will Figure 4D An example is described in . Figure 4D 400D is illustrated illustrating an example scenario of multiple transmissions in SBFD communications according to an embodiment of the present disclosure. Figure 4D As shown in , the PUSCH scheduled by DCI#1 or DCI#2 is transmitted on a half-duplex TDD symbol / slot, and when determining the time domain resources of multiple PUSCHs, SBFD symbols / slots #5 to #7 will be skipped and not counted.

[0082] In some embodiments, the transmission may be scheduled by a single DCI. The indication may include at least one of the following: an explicit indication in the DCI, a type of a first time interval during which the terminal device 110 sends or receives a first transmission in a transmission set based on the DCI, a frequency resource allocation in the DCI, and a first index of a first BWP in the DCI or a second index of a second BWP in the DCI. The first BWP corresponds to a time interval associated with a sub-band full-duplex mode, and the second BWP corresponds to a time interval associated with a half-duplex mode. The solution is simple and clear, and multiple transmissions can be performed in one TDD symbol / time slot and / or SBFD symbol / time slot.

[0083] In some embodiments, the terminal device 110 may determine whether multiple PUSCHs scheduled by a single DCI are to be transmitted on TDD symbols / slots or on SBFD symbols / slots based on an explicit indication in the DCI.

[0084] In some embodiments, the terminal device 110 may determine whether multiple PUSCHs scheduled by a single DCI are transmitted on TDD symbols / slots or on SBFD symbols / slots based on the first symbol / slot format for the first PUSCH transmission determined by the K2 indication. If the symbol / slot of the first PUSCH transmission is a SBFD symbol / slot, the multiple PUSCHs are determined to be all transmitted on the SBFD symbol / slot.

[0085] In some embodiments, the terminal device 110 may determine whether multiple PUSCHs scheduled by a single DCI are sent on TDD symbols / time slots or on SBFD symbols / time slots based on frequency resource allocation. For example, if the frequency resources allocated for PUSCH are not within the UL subband, multiple PUSCHs will all be sent on TDD symbols / time slots, otherwise, multiple PUSCHs will all be sent on SBFD symbols / time slots.

[0086] In some embodiments, the terminal device 110 may determine whether multiple PUSCHs scheduled by a single DCI are sent on TDD symbols / time slots or SBFD symbols / time slots based on the BWP indication in the scheduling DCI. In this embodiment, the BWP in the TDD symbol / time slot is different from the BWP in the SBFD symbol / time slot. For example, the BWP of the SBFD symbol may include only one subband. The terminal device 110 may determine the symbol / time slot type of multiple transmissions based on the corresponding BWP ID.

[0087] In some alternative embodiments, the transmission may be a CG transmission configured by RRC configuration, and / or a CG transmission activated by activation DCI. If the CG transmission is configured to be sent on a TDD symbol / slot, the SBFD symbol / slot will not be counted when calculating the time domain position of the CG PUSCH opportunity based on the period configuration. If the CG transmission is configured to be sent on a SBFD symbol / slot, the TDD symbol / slot (UL / flexible symbol / slot configured by tdd-UL-DL-ConfigurationCommon / tdd-UL-DL-ConfigurationDedicated) will not be counted when calculating the CG period. The indication may include at least one of the following items: whether subband information is present in the activation DCI, the type of the first time interval during which the terminal device 110 sends or receives the first transmission in the transmission set based on the activation DCI, the CG (configuration authorization) configuration index indication in the activation DCI, and the RRC configuration of the first group of CG configuration indices or the second group of CG configuration indices. The first set of CG configuration indices corresponds to time intervals associated with subband full-duplex mode, and the second set of CG configuration indices corresponds to time intervals associated with half-duplex mode. For example, if the activation DCI includes UL subband information, the CG configuration is only used for SBFD symbols / time slots; otherwise, the CG UL configuration is used for TDD symbols / time slots. In some embodiments, the terminal device 110 can determine whether the CG transmission is sent on a TDD symbol / time slot or on a SBFD symbol / time slot based on the symbol / time slot format of the first CG transmission determined by the K2 indication in the activation DCI. In some embodiments, different CG IDs can be configured for TDD symbols / time slots and SBFD symbols / time slots, and the terminal device 110 can determine whether the CG transmission is sent on a TDD symbol / time slot or on a SBFD symbol / time slot based on the corresponding CG ID. This solution is simple and clear, and enables multiple transmissions to be sent in one TDD symbol / time slot and / or SBFD symbol and / or time slot, thereby achieving a smaller regulatory impact.

[0088] In some alternative embodiments, a CG configured CG PUSCH is transmitted only on TDD symbols / slots. SBFD symbols / slots are valid only for dynamic scheduling, for example, DG PUSCH is scheduled on the UL subband in the DL symbol / slot configured by tdd-UL-DL-ConfigurationCommon / tdd-UL-DL-ConfigurationDedicated. In the case where the CG PUSCH timing overlaps with the SBFD symbol / slot determined based on the periodic parameters, the terminal device 110 determines the symbol / slot as an invalid symbol / slot and cancels the CG PUSCH transmission. This solution has no regulatory impact and provides a simple and clear scheduling scheme.

[0089] Example 4

[0090] In this embodiment, in the case where the transmission opportunity overlaps with the SBFD symbol / time slot (and the TDD symbol / time slot), the terminal device 110 determines whether the SBFD symbol / time slot is a valid symbol / time slot for transmission or an invalid symbol / time slot based on the scheduling DCI indication. For example, if the DCI indicates the SBFD symbol / time slot as an invalid symbol / time slot for PUSCH transmission (for example, due to interference on the SBFD symbol / time slot), when the PUSCH opportunity overlaps with the SBFD symbol, the PUSCH opportunity is an invalid PUSCH, and the terminal device 110 will not send PUSCH.

[0091] In some embodiments, after receiving an indication that the time interval associated with the sub-band full-duplex mode is a valid time interval of the transmission set, the terminal device 110 may send or receive a transmission within the time interval. After receiving an indication that the time interval associated with the sub-band full-duplex mode is an invalid time interval of the transmission set, the terminal device 110 may cancel the transmission or postpone the sending or receiving of the transmission to a subsequent time interval associated with the half-duplex mode. Considering the cross-link interference of transmissions in SBFD symbols, the solution of embodiment 4 enhances the flexibility of transmissions in SBFD symbols / time slots to accommodate link adaptation under different channel conditions.

[0092] Example 5

[0093] In this embodiment, the terminal device 110 does not expect multiple transmissions across different symbols / slots with relative transmission directions provided by tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated, for example, UL unique symbols / slots and DL symbols / slots with UL subbands, or DL ​​unique symbols / slots and UL symbols / slots with DL subbands.

[0094] In some embodiments, if a time interval is a time interval associated with a sub-band full-duplex mode, and another time interval in the time interval set is a time interval associated with a half-duplex mode, and another transmission in the transmission set is indicated to be sent or received by the terminal device 110 in the other time interval, the terminal device 110 may determine the transmission set as an error condition.

[0095] To illustrate, we will Figure 4E An example is described in . Figure 4E A diagram 400E is illustrated illustrating an example scenario of multiple transmissions in SBFD communication according to an embodiment of the present disclosure. For example, the network device 120 does not schedule resources spanning UL symbols / time slots and DL symbols / time slots with UL subbands for multiple UL transmissions. Figure 4E As shown in , the four PUSCHs scheduled by DCI#1 will intersect with the UL symbol / slot and the DL symbol / slot with the UL subband. If the terminal device 110 receives DCI#1, the terminal device 110 determines it as an error situation. The two PUSCHs scheduled by DCI#2 are only located on the flexible symbol / slot and the UL symbol / slot, so the terminal device 110 will send the two PUSCHs scheduled by DCI#2. This solution of embodiment 5 reduces the complexity of transmission in the SBFD scheme.

[0096] Example 6

[0097] In this embodiment, frequency hopping may be enabled for the terminal device 110. The terminal device 110 may determine how to send a transmission hop that overlaps with a SBFD symbol / time slot based on the frequency resource determination for the transmission hop. This embodiment of the present application defines explicit UE behavior for a UE with SBFD capability to operate UL transmissions that overlap with SBFD symbols / time slots when frequency hopping is enabled for UL transmissions.

[0098] In some embodiments, network device 120 may send 320 a frequency hopping indication 322 of the transmission set to terminal device 110. Terminal device 110 may receive 320 the frequency hopping indication and, based on the frequency hopping indication, alternately use the first frequency resource and the second frequency resource to send multiple transmissions in the transmission set.

[0099] In some embodiments, inter-slot frequency hopping may be applied to multiple transmissions. For example, odd-numbered transmissions may be indicated as being sent or received using a first frequency resource; and even-numbered transmissions may be indicated as being sent or received using a second frequency resource. In some embodiments, the second frequency resource may be determined based on the first frequency resource and a frequency offset.

[0100] In case of inter-slot frequency hopping, when PUSCH DMRS bundling is not enabled, the slot The starting RB of the period is given by equation (1):

[0101]

[0102] in is the current slot number within the system radio frame in which a multi-slot PUSCH transmission can take place, RB start is the starting RB within the UL BWP, calculated based on the resource block allocation information of resource allocation type 1 (as described in Section 6.1.2.2.2), RB offset is the frequency offset in RBs between two frequency hops.

[0103] In case of inter-slot frequency hopping, when PUSCH-DMRS bundling is enabled, the slot The starting RB of the period is given by equation (2):

[0104]

[0105] in is the current time slot number within the system radio frame, n f is the number of the system radio frame containing the current time slot, is the number of slots per frame of the subcarrier spacing configuration μ on which the UL BWP of the PUSCH is transmitted, N FH It is the value of the higher-level parameter PUSCH frequency mapping interval, RB start is the starting RB within the UL BWP, calculated based on the resource block allocation information of resource allocation type 1 (as described in Section 6.1.2.2.2), RB offset is the RB frequency offset between two frequency hops.

[0106] In some alternative embodiments, intra-slot frequency hopping may be applied to each of the plurality of transmissions. For example, a first portion of each transmission may be indicated as being sent or received using a first frequency resource; and a second portion of each transmission may be indicated as being sent or received using a second frequency resource.

[0107] In the case of intra-slot frequency hopping, the starting RB in each hop is given by equation (3):

[0108]

[0109] Where i=0 and i=1 are the first and second hops respectively, RB startis the starting RB in the UL BWP, calculated according to the resource block allocation information of resource allocation type 1 (as described in Section 6.1.2.2.2) or according to the resource allocation of MsgA PUSCH (as described in [6, TS 38.213]), RB offset is the frequency offset in RBs between two frequency hops. The number of symbols in the first hop is given by The number of symbols in the second hop is given by Given, where It is the length of PUSCH transmission in OFDM symbols in a time slot.

[0110] The terminal device 110 may determine how to handle transmissions with variable frequency domain resources due to frequency hopping. Figure 5A-Figure 5C Some example embodiments are described with respect to performing operations related to sending transmission hopping. It should be understood that the first hop of the transmission may be an odd-numbered transmission in the inter-slot hopping, and the second hop of the transmission may be an even-numbered transmission in the inter-slot hopping; or the first hop of the transmission may be the first part of each transmission in the intra-slot hopping (e.g., the first part of the PUSCH), and the second hop of the transmission may be the second part of the corresponding transmission in the intra-slot hopping (e.g., the second part of the PUSCH).

[0111] In some embodiments, if a first hop of a transmission overlaps with a time interval associated with a half-duplex mode and a second hop of a transmission overlaps with a time interval associated with a sub-band full-duplex mode, if the time interval associated with the sub-band full-duplex mode is invalid for sending the second hop of the transmission, the terminal device 110 may cancel sending the second hop of the transmission. In other words, the terminal device 110 may determine whether to send the hop of the transmission based on the corresponding frequency resource allocation. If the hop of the transmission is located in the UL sub-band in the allocated SBFD symbol / time slot, indicating that the allocated SBFD symbol / time slot is valid for sending the hop, the terminal device 110 then sends the hop on the allocated SBFD symbol / time slot. If the hop of the transmission is located in the DL sub-band or guard band in the allocated SBFD symbol / time slot, indicating that the allocated SBFD symbol / time slot is invalid for sending the hop, the terminal device 110 then cancels sending the hop.

[0112] To illustrate, we will Figure 5A An example is described in . Figure 5A Schematic diagram 500A illustrating an example scenario of transmission with frequency hopping in SBFD communication according to an embodiment of the present disclosure is illustrated. Figure 5AAs shown in , the first hop of the transmission is intended to be sent by the terminal device 110 at the first frequency resource at TDD symbol / time slot #4; and the second hop of the transmission is intended to be sent by the terminal device 110 at the second frequency resource at SBFD symbol / time slot #5. The frequency resource determined for the second hop of the transmission is located in the UL subband of SBFD symbol / time slot #5 and does not overlap with the DL / SSB symbol / time slot. Therefore, SBFD symbol / time slot #5 is valid for the second hop of the transmission, and the terminal device 110 sends the second hop of the transmission. In some embodiments, if the frequency resource determined for the second hop of the transmission is located in the DL subband or guard band of SBFD symbol / time slot #5, the second hop of the transmission will be cancelled. In this way, a flexible scheduling scheme can be provided.

[0113] In some alternative embodiments, if a first hop of transmission overlaps with a time interval associated with half-duplex mode, and a second hop of transmission overlaps with a time interval associated with sub-band full-duplex mode, the terminal device 110 may postpone the second hop of transmission to a subsequent time interval associated with half-duplex mode. In other words, the terminal device 110 performs frequency hopping on only one time interval, such as only TDD symbols / time slots or only SBFD symbols / time slots.

[0114] To illustrate, we will Figure 5B An example is described in . Figure 5B A schematic diagram 500B illustrating an example scenario of transmission with frequency hopping in SBFD communication according to an embodiment of the present disclosure is illustrated. The terminal device 110 may perform frequency hopping on only one type of symbol / time slot, such as a TDD symbol / time slot or a SBFD symbol / time slot. Figure 5B As shown in , if the first hop of the transmission is in a TDD symbol (e.g., UL symbol) in symbol / time slot #4, then when determining the time resource for the second hop of the transmission, time slots #5 to #7 with UL subbands will be skipped. The second hop of the transmission will be delayed to the next TDD time slot, for example, as Figure 5B TDD flexible symbol / slot #8 shown in FIG. In this way, variable frequency domain resources for transmission with frequency hopping can be avoided and a flexible scheduling scheme can be provided.

[0115] In some alternative embodiments, if the second hop of the transmission is indicated to be sent by the terminal device 110 using the second frequency resource, the terminal device 110 may determine the second frequency resource based on the first frequency resource and a first frequency offset associated with the time interval associated with the sub-band full-duplex mode. The first frequency offset is different from a second frequency offset associated with the time interval associated with the half-duplex mode. The terminal device 110 may send the second hop of the transmission using the second frequency resource within the time interval.

[0116] To illustrate, we will Figure 5C An example is described in . Figure 5C A schematic diagram 500C illustrating an example scenario of transmission with frequency hopping in SBFD communication according to an embodiment of the present disclosure is illustrated. The network device 120 may configure / indicate two frequency offsets for TDD symbols / time slots and SBFD symbols / time slots, respectively. The terminal device 110 may perform frequency hopping of the PUSCH based on the symbol / time slot type of the time domain resources allocated for the transmission hop and the associated frequency offset. Figure 5C As shown in , the first frequency offset of the transmission hop in SBFD symbol / time slot #5 is different from the second frequency offset of the transmission hop in TDD symbol / time slot #9. In this way, continuous transmission of multiple transmissions with frequency hopping on TDD symbol / time slot and SBFD symbol / time slot can be achieved, thereby achieving reduced latency and better coverage.

[0117] In addition, in SBFD symbols / time slots, potential conflicts may occur between higher configuration DL transmissions and UL transmissions, and it is unclear how to handle such conflicts. In view of this problem, embodiments of the present disclosure provide a solution for handling potential conflicts in SBFD symbols / time slots to support SBFD operations. Figures 6 to 7D Describe the solution in detail.

[0118] Figure 6 FIG. 6 is a diagram illustrating a communication process 600 for DL ​​transmission and UL transmission in SBFD communication according to an embodiment of the present disclosure. For discussion purposes, reference will be made to FIG. Figure 1 Process 600 is described. Process 600 may involve Figure 1 The terminal device 110 and the network device 120 shown. It should be understood that Figure 6 The steps and order of steps in the embodiment are for illustration only and are not intended to be limiting. For example, the order of the steps may be changed. Some steps may be omitted, or any other suitable additional steps may be added.

[0119] like Figure 6 As shown in , the network device 120 sends (614) to the terminal device 110 a first indication 616 of a DL transmission to be received by the terminal device 110 in the DL subband in a time interval associated with the subband full-duplex mode. The network device 120 sends (620) to the terminal device 110 a second indication 622 of a first UL transmission to be sent by the terminal device 110 in the UL subband in a time interval associated with the subband full-duplex mode. The terminal device 110 receives (618, 624) the first indication 616 of the DL transmission and the second indication 622 of the first UL transmission. Based on the preconfigured resource allocation, the terminal device 110 may determine the time and frequency resources indicated for the DL transmission and the first UL transmission.

[0120] After determining (626) that the DL transmission overlaps with the first UL transmission in the time domain, the terminal device 110 performs an operation (628) related to the DL transmission or the first UL transmission. Embodiments of the present application define clear UE behaviors for SBFD-capable UEs to handle conflicts between UL transmissions and DL transmissions in SBFD symbols / time slots.

[0121] In some embodiments, the network device 120 may send (602) a TDD configuration 604, such as tdd-UL-DL-ConfigurationCommon and / or tdd-UL-DL-ConfigurationDedicated, to the terminal device 110. The terminal device 110 receives (606) the TDD configuration 604 and thereby determines the direction of transition over a time interval (e.g., symbol / time slot). The network device 120 may send (608) an SBFD configuration 610, such as the time and frequency resources of the UL subband, to the terminal device 110. The terminal device 110 receives (612) the SBFD configuration 610 and thereby knows the configuration of the SBFD symbol / time slot. Based on the TDD configuration and the SBFD configuration, the terminal device 110 may determine the time and frequency resources indicated for the scheduled transmission.

[0122] Will combine Figure 7A-7D Some example embodiments are described with respect to performing operations related to sending or receiving transmissions. Figure 7A-7D The DL transmission in the SBFD symbol / time slot is illustrated as SSB, and the first UL transmission is illustrated as PUSCH, but the concepts of these embodiments can be applied to other DL and UL transmissions. It should be understood that the number and period of scheduled transmissions and the number of transmissions in one SBFD symbol / time slot are given for illustrative purposes and do not impose any limitations on the present disclosure.

[0123] Example 7

[0124] In this embodiment, a behavior for handling a conflict between a UL transmission and a DL transmission in a SBFD symbol / time slot may be predefined. For example, in some embodiments, a behavior for handling a conflict between a UL transmission and a DL transmission in a SBFD symbol / time slot may be determined based on predefined priorities of the UL transmission and the DL transmission. For example, if the priority of the first UL transmission is lower than the priority of the DL transmission, the terminal device 110 may abandon the first UL transmission and receive the DL transmission. If the priority of the DL transmission is lower than the priority of the UL transmission, the terminal device 110 may stop receiving the DL transmission and send the UL transmission.

[0125] In some embodiments, if the DL transmission is a semi-persistently scheduled physical downlink shared channel (SPSPDSCH), the terminal device 110 stops receiving the SPS PDSCH and performs sending the first UL transmission. In some embodiments, if the first UL transmission is a physical random access channel (PRACH), the terminal device 110 stops receiving the DL transmission and performs sending the UL transmission.

[0126] In some alternative embodiments, the behavior for handling conflicts between UL transmissions (e.g., DG PUSCH (single PUSCH scheduling), multiple PUSCHs scheduled by a single DCI, CG PUSCH / PUCCH, PUSCH / PUCCH repetitions, and PRACH) and DL transmissions (e.g., SSB, SPS PDSCH, and multiple PDSCHs scheduled by a single DCI) in SBFD symbols / time slots may be predefined according to Table 1.

[0130] To illustrate, we will Fig. 7A An example is described in . Fig. 7A Schematic diagram 700A illustrating an example scenario of UL transmission and DL transmission in SBFD communication according to an embodiment of the present disclosure is illustrated. Fig. 7A As shown in , since the CG PUSCH transmission overlaps with the SSB transmission in SBFD symbol / time slot #5, the terminal device 110 cancels the CG PUSCH transmission and receives the SSB transmission in SBFD symbol / time slot #5. In this way, a simple and clear scheduling scheme for conflicts between UL transmission and DL transmission is provided.

[0131] Example 8

[0132] In this embodiment, the overlap between DL transmission and UL subband in SBFD symbol / time slot, and the processing order of potential conflict between DL transmission and UL transmission can be predefined. For example, in some embodiments, the terminal device 110 can first process the overlap between DL transmission and UL subband, for example, cancel DL transmission or send DL transmission only in frequency resources in DL subband. After the overlap between DL transmission and UL subband is resolved, the terminal device 110 can then resolve the potential conflict (if any) between DL transmission and UL transmission. This can avoid some unnecessary UL transmission discards.

[0133] For example, if the DL transmission will at least partially overlap with the UL subband or the guard band between the UL subband and the DL subband, the terminal device 110 may cancel the DL transmission. Alternatively, if the DL transmission will at least partially overlap with the UL subband or the guard band between the UL subband and the DL subband, the terminal device 110 may determine the portion of the DL transmission located in the DL subband as the target DL transmission. When there is no overlap between the DL transmission and the UL subband, if the DL transmission will overlap with the first UL transmission in the time domain, the terminal device 110 may resolve a potential conflict between the DL transmission and the first UL transmission.

[0134] To illustrate, we will Figure 7B An example is described in . Figure 7B Schematic diagram 700B illustrating an example scenario of UL transmission and DL transmission in SBFD communication according to an embodiment of the present disclosure is illustrated. Figure 7B As shown in , in SBFD symbol / time slot #5, the CG PUSCH transmission overlaps with the SSB transmission, and part of the SSB transmission overlaps with the UL subband and the guard band. In some embodiments, the terminal device 110 can cancel the SSB transmission to resolve the overlap between the SSB transmission and the UL subband. Since the SSB transmission is canceled, the terminal device 110 can send a CG PUSCH transmission in SBFD symbol / time slot #5.

[0135] Alternatively, the terminal device 110 may determine a portion of the SSB transmission located at the DL subband as the target DL transmission to resolve the overlap between the SSB transmission and the UL subband. Since the CG PUSCH transmission overlaps with the determined target DL transmission (i.e., a portion of the SSB transmission located at the DL subband) in SBFD symbol / time slot #5, the terminal device 110 may cancel the CG PUSCH transmission and receive the portion of the SSB transmission located at the DL subband in SBFD symbol / time slot #5.

[0136] In some alternative embodiments, the terminal device 110 may first handle the overlap between the DL transmission and the UL transmission, for example based on a predefined priority. After the potential conflict between the DL transmission and the UL transmission is resolved, the terminal device 110 may then handle the overlap between the DL transmission and the UL subband, for example, canceling the DL transmission or sending the DL transmission only in the frequency resources in the DL subband. For example, if the DL transmission will overlap with the first UL transmission in the time domain, the terminal device 110 may determine one of the first UL transmission and the DL transmission as the target transmission to resolve the potential conflict between the first UL transmission and the DL transmission. When there is no potential conflict between the DL transmission and the first UL transmission, if the DL transmission will at least partially overlap with the UL subband, the terminal device 110 may cancel the DL transmission or receive only the portion of the DL transmission located in the DL subband. This solution may demonstrate a unified conflict handling rule for the overlap between the DL transmission and the UL transmission in the SBFD symbol.

[0137] For example, in Figure 7B In the scenario shown, since the CG PUSCH transmission overlaps with the SSB transmission in SBFD symbol / time slot #5, the terminal device 110 can cancel the CG PUSCH transmission in the SBFD symbol / time slot #5 and determine the SSB transmission as the target transmission. When there is an overlap between the SSB transmission and the UL subband, the terminal device 110 can cancel the SSB transmission, or receive only the portion of the SSB transmission located at the DL subband in the SBFD symbol / time slot #5. The solution of embodiment 8 provides a simple and clear scheduling scheme for the coexistence of conflicts between UL transmissions and DL transmissions, and overlaps between DL transmissions and UL subbands.

[0138] Example 9

[0139] In this embodiment, the order of handling potential conflicts between multiple UL transmissions and potential conflicts between DL transmissions and UL transmissions in SBFD symbols / time slots may be predefined. For example, in some embodiments, the terminal device 110 may first handle potential conflicts between multiple UL transmissions, for example, by reusing the multiplexing / priority rules in Rel-16 / Rel-17. When there is no potential conflict between UL transmissions in a SBFD symbol / time slot, the terminal device 110 may, for example, handle potential conflicts (if any) between DL transmissions and UL transmissions in the SBFD symbol / time slot by following the predefined rules in Table 1.

[0140] For example, the terminal device 110 may receive from the network device 120 a third indication of a second UL transmission to be sent by the terminal device 110 in the UL subband within a time interval associated with the subband full-duplex mode. If the second UL transmission will overlap with the first UL transmission in the time domain, the terminal device 110 may first determine a target UL transmission based on the first UL transmission and the second UL transmission to resolve a potential conflict between the first UL transmission and the second UL transmission. In some embodiments, the target UL transmission may be one of the following: the first UL transmission, the second UL transmission, or an adjusted first UL transmission determined by multiplexing a portion of the UCI on the second UL transmission in the first UL transmission. After resolving the potential conflict between the UL transmissions, the terminal device 110 may resolve the potential conflict between the DL transmission and the target UL transmission.

[0141] To illustrate, we will Figure 7C An example is described in . Figure 7C Schematic diagram 700C illustrating an example scenario of UL transmission and DL transmission in SBFD communication according to an embodiment of the present disclosure is illustrated. Figure 7C As shown in , in SBFD symbol / time slot #5, the CG PUSCH transmission overlaps with the SSB transmission and the PUCCH transmission. In some embodiments, in order to resolve the overlap between the CG PUSCH transmission and the PUCCH transmission in SBFD symbol / time slot #5, the terminal device 110 may multiplex the UCI in the PUCCH transmission onto the CG PUSCH transmission. The CG PUSCH transmission with the multiplexed UCI may be determined as the target UL transmission, and the PUCCH transmission may be canceled. Since the CG PUSCH transmission overlaps with the SSB transmission in SBFD symbol / time slot #5, the terminal device 110 may cancel the CG PUSCH transmission with the multiplexed UCI and receive the SSB transmission in SBFD symbol / time slot #5.

[0142] In some alternative embodiments, the terminal device 110 may first handle potential conflicts between DL transmissions and UL transmissions in SBFD symbols / time slots, for example, by following the predefined rules in Table 1. When there are no potential conflicts between UL transmissions in SBFD symbols / time slots, the terminal device 110 may then handle potential conflicts (if any) between multiple UL transmissions, for example, by reusing the multiplexing / priority rules in Rel-16 / Rel-17. For example, in the case where a first UL transmission will overlap with both a DL transmission and a second UL transmission in the time domain, the terminal device 110 may first determine one of the first UL transmission and the DL transmission as a target transmission to resolve the potential conflict between the first UL transmission and the DL transmission. The terminal device 110 may then resolve the potential conflict (if any) between the target transmission and the second UL transmission.

[0143] To illustrate, we will Fig.7D An example is described in . Fig.7D Schematic diagram 700D illustrating an example scenario of UL transmission and DL transmission in SBFD communication according to an embodiment of the present disclosure is illustrated. Fig.7D As shown in , in SBFD symbol / time slot #5, CG PUSCH transmission overlaps with SSB transmission and PUCCH transmission. In some embodiments, in order to resolve the overlap between CG PUSCH transmission and SSB transmission in SBFD symbol / time slot #5, the terminal device 110 can cancel the CG PUSCH transmission and determine the SSB transmission as the target transmission. Since there is no overlap between the SSB transmission and the PUCCH transmission, the terminal device 110 can first receive the SSB transmission from the network device 120 and then send the PUCCH transmission to the network device 120. It is assumed that the processing time for resolving overlap and / or for switching reception to transmission is met. The solution of Example 9 provides a simple and clear scheduling scheme for the coexistence of conflicts between UL transmissions and conflicts between UL transmissions and DL transmissions. Without this solution, the terminal device and the network device may have different understandings of whether to operate UL transmission or DL ​​transmission, which may reduce transmission performance.

[0144] Example 10

[0145] In this embodiment, the order of processing potential conflicts between multiple UL transmissions and potential conflicts between DL transmissions and UL transmissions in SBFD symbols / time slots can be determined based on the order. In other words, conflicts between multiple UL transmissions and conflicts between DL transmissions and UL transmissions in the same SBFD symbol / time slot can be processed in order. For example, if the overlap between the DL transmission and the first UL transmission in the time domain is earlier than the overlap between the first UL transmission and the second UL transmission in the time domain, the terminal device 110 can first determine one of the DL transmission and the first UL transmission as the target transmission to resolve the potential conflict between the DL transmission and the first UL transmission. If the overlap between the first UL transmission and the second UL transmission in the time domain is earlier than the overlap between the DL transmission and the first UL transmission in the time domain, the terminal device 110 can first determine the target UL transmission based on the first UL transmission and the second UL transmission to resolve the potential conflict between the first UL transmission and the second UL transmission.

[0146] For example, in Fig.7DIn the scenario shown, since the overlap between SSB transmission and CG PUSCH transmission in the time domain is earlier than the overlap between CG PUSCH transmission and PUCCH transmission in the time domain, the terminal device 110 can first process the overlap between SSB transmission and CG PUSCH transmission. The CG PUSCH transmission in SBFD symbol / time slot #5 can be canceled, and the SSB transmission can be determined as the target transmission. When the CG PUSCH transmission is canceled, the overlap between the CG PUSCH transmission and the PUCCH transmission is resolved; the terminal device 110 can therefore first receive the SSB transmission from the network device 120 and then send the PUCCH transmission to the network device 120. The solution of embodiment 10 provides a simple and clear scheduling scheme for the coexistence of conflicts between UL transmissions and conflicts between UL transmissions and DL transmissions.

[0147] Embodiment 11

[0148] In this embodiment, if there is a potential conflict between multiple UL transmissions and a potential conflict between a DL transmission and a UL transmission in the same SBFD symbol / time slot, all UL transmissions can be regarded as one complete UL transmission, and the conflict between the entire UL transmission and the DL transmission can be handled, for example, based on a predefined priority. In other words, if the DL transmission has a higher priority than the entire UL transmission, all UL transmissions can be canceled. In the case where the priority of the DL transmission is lower than the priority of the entire UL transmission, the DL transmission can be discarded and the terminal device can resolve the conflict between the UL transmissions. For example, if the common priority of the first UL transmission and the second UL transmission is lower than the priority of the DL transmission, the terminal device 110 can discard the first UL transmission and the second UL transmission. If the priority of the DL transmission is lower than the common priority of the first UL transmission and the second UL transmission, the terminal device 110 can stop receiving the DL transmission. In this way, a clear solution can be provided.

[0149] In some alternative embodiments, the terminal device 110 may determine the coexistence of overlaps between multiple transmissions and overlaps between UL transmissions and DL transmissions as an error condition. In other words, the terminal device 110 does not expect overlaps between multiple transmissions and overlaps between UL transmissions and DL transmissions to coexist.

[0150] Example 12

[0151] In this embodiment, the behavior for handling conflicts between the transmission direction provided by the TDD configuration (e.g., tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated) and the transmission direction configured for the subband in the same TDD symbol / time slot may be predefined. For example, in some embodiments, when the UL subband is configured in the DL symbol provided by tdd-UL-DL-ConfigurationCommon, the behavior of the transmission direction determination of the terminal device may be predefined. The terminal device may then determine to use SBFD operation to operate reception or transmission in the symbol based on the predefined behavior.

[0152] In some embodiments, the time and frequency resource allocation of the subband is configured for the terminal device by semi-static configuration (e.g., RRC configuration). In some alternative embodiments, the time and frequency resource allocation of the subband is indicated to the terminal device by dynamic indication (e.g., by UE-specific DCI or UE group common DCI).

[0153] In some alternative embodiments, the behavior of the transmission direction for determining conflicts between the transmission direction provided by the TDD configuration (e.g., tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated) and the transmission direction configured for the subband in the same TDD symbol / time slot may be predefined according to Table 2.

[0157] Corresponding to the above process, the embodiment of the present disclosure provides a communication method implemented at a terminal device and a network device. Figure 8 and Fig. 9 Describe these methods.

[0158] Figure 8 An example communication method 800 implemented at a terminal device according to some embodiments of the present disclosure is illustrated. For example, the method 800 may be implemented in a Figure 1 For the purpose of discussion, reference will be made to Figure 1 Method 800 is described. It should be understood that method 800 may include additional blocks not shown and / or may omit some of the blocks shown, and the scope of the present disclosure is not limited in this regard.

[0159] At block 810, terminal device 110 receives from network device 120 an indication of a set of transmissions to be sent or received by terminal device 110 within a set of time intervals. The transmissions in the set of transmissions are indicated as being sent or received by the terminal device within time intervals in the set of time intervals.

[0160] At block 820 , the terminal device 110 determines whether the time interval includes a time interval associated with the sub-band full-duplex mode. If the time interval includes a time interval associated with the sub-band full-duplex mode, the method 800 proceeds to block 830 .

[0161] At block 830, the terminal device 110 performs operations related to sending or receiving a transmission.

[0162] In some embodiments, the terminal device 110 may determine that the time interval is valid for sending or receiving a transmission if the frequency resources allocated for transmission are within a first subband having a first direction in the time interval, the first direction being the same as the direction of transmission between the terminal device and the network device.

[0163] In some embodiments, if the frequency resource overlaps with a second subband having a second direction or overlaps with a guard band between the first subband and the second subband, the second direction being different from the first direction, the terminal device 110 may determine that the time interval is invalid for sending or receiving a transmission.

[0164] In some embodiments, terminal device 110 may cancel a transmission if the time resource of the transmission at least partially overlaps with a time interval that is invalid for sending or receiving transmissions.

[0165] In some embodiments, if a first portion of the time resources for a transmission overlaps with a time interval that is invalid for sending or receiving a transmission, and a second portion of the time resources for the transmission overlaps with a time interval associated with a half-duplex mode, the terminal device 110 may send or receive a portion of the transmission that is in the time interval associated with the half-duplex mode.

[0166] In some embodiments, if the frequency resource overlaps with a second subband having a second direction or overlaps with a guard band between the first subband and the second subband, the second direction being different from the first direction, the terminal device 110 may determine the transmission set as an error condition.

[0167] In some embodiments, the bandwidth part (BWP) available for the time interval may include at least: a first subband having a first direction in the time interval, and a second subband having a second direction, wherein the first direction is the same as the direction of transmission between the terminal device and the network device, and the second direction is opposite to the first direction.

[0168] In some embodiments, the terminal device 110 may determine a frequency resource allocation for the transmission based on a reference BWP including the first sub-band; and send or receive the transmission in the time interval based on the frequency resource allocation.

[0169] In some embodiments, the terminal device 110 may determine a frequency resource allocation for transmission based on a BWP available for the time interval. The BWP includes: a first subband having a first direction in the time interval. The first direction is the same as the direction of transmission between the terminal device and the network device. The terminal device 110 may send or receive transmissions in the time interval based on the frequency resource allocation.

[0170] In some embodiments, the terminal device 110 may receive information of frequency resource allocation for transmission from a network device, the information comprising: a first frequency resource indicator for a time interval associated with a half-duplex mode, and a second frequency resource indicator for a time interval associated with a sub-band full-duplex mode.

[0171] In some embodiments, the terminal device 110 may determine a frequency resource allocation for the transmission based on the second frequency resource indicator; and send or receive the transmission within the time interval based on the frequency resource allocation.

[0172] In some embodiments, terminal device 110 may receive an indication from a network device whether a transmission set is to be sent or received by the terminal device in a time interval associated with half-duplex mode or in a time interval associated with sub-band full-duplex mode.

[0173] In some embodiments, if based on the indication, the transmission set is to be sent or received in a time interval associated with the sub-band full-duplex mode, the terminal device 110 may send or receive the transmission in the time interval. If based on the indication, the transmission set is to be sent or received in a time interval associated with the half-duplex mode, the terminal device 110 may skip the time interval associated with the sub-band full-duplex mode and postpone sending or receiving the transmission to a subsequent time interval associated with the half-duplex mode.

[0174] In some embodiments, the indication may include at least one of the following items: an explicit indication in downlink control information (DCI), the type of a first time interval during which the terminal device sends or receives a first transmission in a transmission set based on the DCI, a frequency resource allocation in the DCI, a first index of a first BWP in the DCI (the first BWP corresponds to a time interval associated with a sub-band full-duplex mode), and a second index of a second BWP in the DCI (the second BWP corresponds to a time interval associated with a half-duplex mode).

[0175] In some embodiments, the indication may include at least one of the following items: whether subband information is present in the activation DCI, the type of the first time interval during which the terminal device sends or receives the first transmission in the transmission set based on the activation DCI, the frequency resource allocation in the activation DCI, the first configuration authorization configuration index in the radio resource control (RRC) configuration (the first configuration authorization configuration index corresponds to the time interval associated with the subband full-duplex mode), and the second configuration authorization configuration index in the RRC configuration (the second configuration authorization configuration index corresponds to the time interval associated with the half-duplex mode).

[0176] In some embodiments, in response to receiving an indication that the time interval associated with the sub-band full-duplex mode is a valid time interval of the transmission set, the terminal device 110 may send or receive a transmission in the time interval. In response to receiving an indication that the time interval associated with the sub-band full-duplex mode is an invalid time interval of the transmission set, the terminal device 110 may cancel the transmission or postpone sending or receiving the transmission to a subsequent time interval associated with the half-duplex mode.

[0177] In some embodiments, if the time interval is a time interval associated with a sub-band full-duplex mode, and another time interval in the time interval set is a time interval associated with a half-duplex mode, and another transmission in the transmission set is indicated to be sent or received by the terminal device in the other time interval, the terminal device 110 may determine the transmission set as an error condition.

[0178] In some embodiments, a transmission set is a plurality of repetitions of a transmission.

[0179] In some embodiments, the terminal device 110 may receive a frequency hopping indication of a transmission set from a network device; and send multiple transmissions in the transmission set by alternately using a first frequency resource and a second frequency resource based on the frequency hopping indication.

[0180] In some embodiments, if a first hop of a transmission overlaps with a time interval associated with a half-duplex mode, and a second hop of a transmission overlaps with a time interval associated with a sub-band full-duplex mode, if the time interval associated with the sub-band full-duplex mode is invalid for sending the second hop of the transmission, the terminal device 110 may cancel the second hop of sending the transmission; or postpone the second hop of sending the transmission to a subsequent time interval associated with the half-duplex mode.

[0181] In some embodiments, if the second hop of the transmission is indicated to be sent by the terminal device using the second frequency resource, the terminal device 110 may determine the second frequency resource based on the first frequency resource and a first frequency offset associated with the time interval associated with the sub-band full-duplex mode. The first frequency offset is different from a second frequency offset associated with the time interval associated with the half-duplex mode. The terminal device 110 may send the second hop of the transmission using the second frequency resource within the time interval.

[0182] pass Figure 8 The method can well support the sub-band non-overlapping full-duplex scheme regarding resource allocation.

[0183] Fig. 9 Another example communication method 900 implemented at a terminal device according to some embodiments of the present disclosure is illustrated. For example, the method 900 may be implemented in a Figure 1 For the purpose of discussion, reference will be made to Figure 1 Method 900 is described. It should be understood that method 900 may include additional blocks not shown and / or may omit some of the blocks shown, and the scope of the present disclosure is not limited in this regard.

[0184] At block 910, the terminal device 110 receives from the network device 120 a first indication of a downlink transmission to be received by the terminal device in a downlink sub-band within a time interval associated with the sub-band full-duplex mode.

[0185] At block 920, the terminal device 110 receives from the network device 120 a second indication of a first uplink transmission to be sent by the terminal device in the uplink sub-band within a time interval associated with the sub-band full-duplex mode.

[0186] At block 930 , the terminal device 110 determines whether the downlink transmission overlaps with the first uplink transmission in the time domain. If the downlink transmission overlaps with the first uplink transmission in the time domain, the method 900 continues to block 940 .

[0187] At block 940, the terminal device 110 performs operations related to a downlink transmission or a first uplink transmission.

[0188] In some embodiments, if the priority of the first uplink transmission is lower than the priority of the downlink transmission, the terminal device 110 may discard the first uplink transmission. If the priority of the downlink transmission is lower than the priority of the first uplink transmission, the terminal device 110 may stop receiving the downlink transmission.

[0189] In some embodiments, the downlink transmission may be a Semi-Persistently Scheduled Physical Downlink Shared Channel (SPSPDSCH).The terminal device 110 may stop receiving the SPS PDSCH.

[0190] In some embodiments, if the first uplink transmission is a Physical Random Access Channel (PRACH), the terminal device 110 may stop receiving downlink transmissions.

[0191] In some embodiments, if the downlink transmission at least partially overlaps with the uplink sub-band or the guard band between the uplink sub-band and the downlink sub-band, the terminal device 11 may cancel the downlink transmission; or determine the portion of the downlink transmission located in the downlink sub-band as the target downlink transmission.

[0192] In some embodiments, the terminal device 110 may resolve a potential conflict between a downlink transmission and a first uplink transmission if there is no overlap between the downlink and uplink subbands and the downlink transmission would overlap with the first uplink transmission in the time domain.

[0193] In some embodiments, if the downlink transmission will overlap with the first uplink transmission in the time domain, the terminal device 110 may determine one of the first uplink transmission and the downlink transmission as the target transmission to resolve potential conflicts between the first uplink transmission and the downlink transmission.

[0194] In some embodiments, the terminal device 110 may cancel the downlink transmission if there is no potential conflict between the downlink transmission and the first uplink transmission and the downlink transmission will at least partially overlap with the uplink subband; or receive a portion of the downlink transmission that is in the downlink subband.

[0195] In some embodiments, the terminal device 110 may receive from the network device a third indication of a second uplink transmission to be sent by the terminal device in the uplink sub-band within a time interval associated with the sub-band full-duplex mode.

[0196] In some embodiments, if the second uplink transmission will overlap with the first uplink transmission in the time domain, the terminal device 110 can determine a target uplink transmission based on the first uplink transmission and the second uplink transmission to resolve a potential conflict between the first uplink transmission and the second uplink transmission; and resolve a potential conflict between the downlink transmission and the target uplink transmission.

[0197] In some embodiments, the target uplink transmission may be one of: the first uplink transmission, the second uplink transmission, or an adjusted first uplink transmission determined by multiplexing a portion of the second uplink transmission in the first uplink transmission.

[0198] In some embodiments, if the second uplink transmission will overlap with the first uplink transmission in the time domain, the terminal device 110 may determine one of the first uplink transmission and the downlink transmission as the target transmission to resolve a potential conflict between the first uplink transmission and the downlink transmission; and resolve a potential conflict between the target transmission and the second uplink transmission.

[0199] In some embodiments, if the overlap of the downlink transmission and the first uplink transmission in the time domain is earlier than the overlap of the first uplink transmission and the second uplink transmission in the time domain, the terminal device 110 may determine one of the first uplink transmission and the downlink transmission as the target transmission to resolve the potential conflict between the downlink transmission and the first uplink transmission. If the overlap of the first uplink transmission and the second uplink transmission in the time domain is earlier than the overlap of the downlink transmission and the first uplink transmission in the time domain, the terminal device 110 may determine the target uplink transmission based on the first uplink transmission and the second uplink transmission to resolve the potential conflict between the first uplink transmission and the second uplink transmission.

[0200] In some embodiments, if the common priority of the first uplink transmission and the second uplink transmission is lower than the priority of the downlink transmission, the terminal device 110 may discard the first uplink transmission and the second uplink transmission. If the priority of the downlink transmission is lower than the common priority of the first uplink transmission and the second uplink transmission, the terminal device 110 may stop receiving the downlink transmission.

[0201] In some embodiments, the terminal device 110 may determine the coexistence of an overlap between the first uplink transmission and the second uplink transmission and an overlap between the first uplink transmission and the downlink transmission as an error condition.

[0202] use Fig. 9 The method can support a sub-band non-overlapping full-duplex scheme for potential transmission conflicts.

[0203] Fig.10 An example communication method 1000 implemented at a network device according to some embodiments of the present disclosure is illustrated. For example, the method 1000 may be implemented at a network device such as Figure 1 For discussion purposes, reference will be made to the network device 120. Figure 1Method 1000 is described. It should be understood that method 1000 may include additional blocks not shown and / or may omit some of the blocks shown, and the scope of the present disclosure is not limited in this regard.

[0204] At block 1010, network device 120 sends an indication of a set of transmissions to be sent or received by the terminal device within a set of time intervals to terminal device 110. The transmissions in the set of transmissions are indicated as being sent or received by the terminal device within time intervals in the set of time intervals.

[0205] At block 1020, if the time interval includes a time interval associated with a sub-band full-duplex mode, the network device 120 performs operations related to receiving or sending a transmission by the network device.

[0206] In some embodiments, the network device 120 may determine that a time interval is valid for receiving or sending a transmission if the frequency resources allocated for transmission are within a first subband having a first direction in the time interval, the first direction being the same as the direction of transmission between the terminal device and the network device.

[0207] In some embodiments, network device 120 may determine that the time interval is invalid for receiving or sending a transmission if the frequency resource overlaps a second subband having a second direction, or overlaps a guard band between the first subband and the second subband, the second direction being different from the first direction.

[0208] In some embodiments, network device 120 may cancel a transmission if the time resource of the transmission at least partially overlaps with a time interval that is invalid for receiving or sending transmissions.

[0209] In some embodiments, if a first portion of the time resources for a transmission overlaps with a time interval that is invalid for receiving or sending a transmission, and a second portion of the time resources for the transmission overlaps with a time interval associated with half-duplex mode, the network device 120 may receive or send the portion of the transmission that is in the time interval associated with half-duplex mode.

[0210] In some embodiments, the bandwidth part (BWP) available for the time interval may include at least: a first subband having a first direction in the time interval, and a second subband having a second direction, wherein the first direction is the same as the direction of transmission between the terminal device and the network device, and the second direction is opposite to the first direction.

[0211] In some embodiments, network device 120 may send an indication of a frequency resource allocation for transmissions to terminal device 110 based on a reference BWP including the first subband; and receive or send transmissions in the time interval based on the frequency resource allocation.

[0212] In some embodiments, network device 120 may send an indication of frequency resource allocation for transmission to terminal device 110 based on the BWP available for the time interval. The BWP includes: a first subband having a first direction in the time interval. The first direction is the same as the direction of transmission between the terminal device and the network device. Network device 120 may receive or send transmissions in the time interval based on the frequency resource allocation.

[0213] In some embodiments, the network device 120 may send information of frequency resource allocation for transmission to the terminal device, the information comprising: a first frequency resource indicator for a time interval associated with the half-duplex mode, and a second frequency resource indicator for a time interval associated with the sub-band full-duplex mode.

[0214] In some embodiments, the network device 120 may send an indication of a frequency resource allocation for the transmission to the terminal device 110 based on the second frequency resource indicator; and receive or send the transmission within the time interval based on the frequency resource allocation.

[0215] In some embodiments, network device 120 may send an indication to a terminal device whether a transmission set is to be received or sent by the terminal device in a time interval associated with half-duplex mode or in a time interval associated with sub-band full-duplex mode.

[0216] In some embodiments, in response to the set of transmissions being received or sent in a time interval associated with the sub-band full-duplex mode, the network device 120 may receive or send a transmission in the time interval. In response to the set of transmissions being received or sent in a time interval associated with the half-duplex mode, the network device 120 may skip the time interval associated with the sub-band full-duplex mode and defer receiving or sending the transmission to a subsequent time interval associated with the half-duplex mode.

[0217] In some embodiments, the indication may include at least one of the following items: an explicit indication in downlink control information (DCI), the type of a first time interval during which the terminal device sends or receives a first transmission in a transmission set based on the DCI, a frequency resource allocation in the DCI, a first index of a first BWP in the DCI (the first BWP corresponds to a time interval associated with a sub-band full-duplex mode), and a second index of a second BWP in the DCI (the second BWP corresponds to a time interval associated with a half-duplex mode).

[0218] In some embodiments, the indication may include at least one of the following items: whether subband information is present in the activation DCI, the type of the first time interval during which the terminal device sends or receives the first transmission in the transmission set based on the activation DCI, the frequency resource allocation in the activation DCI, the first configuration authorization configuration index in the radio resource control (RRC) configuration (the first configuration authorization configuration index corresponds to the time interval associated with the subband full-duplex mode), and the second configuration authorization configuration index in the RRC configuration (the second configuration authorization configuration index corresponds to the time interval associated with the half-duplex mode).

[0219] In some embodiments, if the time interval associated with the sub-band full-duplex mode is a valid time interval of the transmission set, the network device 120 may receive or send a transmission within the time interval. If the time interval associated with the sub-band full-duplex mode is an invalid time interval of the transmission set, the network device 120 may cancel the transmission or postpone receiving or sending the transmission to a subsequent time interval associated with the half-duplex mode.

[0220] In some embodiments, a transmission set is a plurality of repetitions of a transmission.

[0221] In some embodiments, the network device 120 may send a frequency hopping indication of the transmission set to the terminal device; and alternately use the first frequency resource and the second frequency resource to receive multiple transmissions in the transmission set based on the frequency hopping indication.

[0222] In some embodiments, if a first hop of a transmission overlaps with a time interval associated with a half-duplex mode, and a second hop of a transmission overlaps with a time interval associated with a sub-band full-duplex mode, if the time interval associated with the sub-band full-duplex mode is invalid for receiving the second hop of the transmission, the network device 120 may cancel the second hop of receiving the transmission; or postpone the second hop of receiving the transmission to a subsequent time interval associated with the half-duplex mode.

[0223] In some embodiments, if the second hop of the transmission is indicated as being sent by the terminal device using the second frequency resource, the network device 120 may send an indication of the second frequency resource to the terminal device 110 based on the first frequency resource and a first frequency offset associated with the time interval associated with the sub-band full-duplex mode. The first frequency offset is different from the second frequency offset associated with the time interval associated with the half-duplex mode. The network device 120 may receive the second hop of the transmission using the second frequency resource in the time interval.

[0224] pass Fig.10 The method can well support the sub-band non-overlapping full-duplex scheme regarding resource allocation.

[0236] In some embodiments, network device 120 may send to the terminal device a third indication of a second uplink transmission to be sent by the terminal device in the uplink sub-band within a time interval associated with the sub-band full-duplex mode.

[0238] In some embodiments, the target uplink transmission may be one of: the first uplink transmission, the second uplink transmission, or an adjusted first uplink transmission determined by multiplexing a portion of the second uplink transmission in the first uplink transmission.

[0239] In some embodiments, if the second uplink transmission will overlap with the first uplink transmission in the time domain, the network device 120 may determine one of the first uplink transmission and the downlink transmission as the target transmission to resolve a potential conflict between the first uplink transmission and the downlink transmission; and resolve a potential conflict between the target transmission and the second uplink transmission.

[0240] In some embodiments, if the overlap of the downlink transmission and the first uplink transmission in the time domain is earlier than the overlap of the first uplink transmission and the second uplink transmission in the time domain, the network device 120 may determine one of the first uplink transmission and the downlink transmission as the target transmission to resolve the potential conflict between the downlink transmission and the first uplink transmission. If the overlap of the first uplink transmission and the second uplink transmission in the time domain is earlier than the overlap of the downlink transmission and the first uplink transmission in the time domain, the network device 120 may determine the target uplink transmission based on the first uplink transmission and the second uplink transmission to resolve the potential conflict between the first uplink transmission and the second uplink transmission.
