[0002] In communication systems, there are mainly two duplex modes for uplink (UL) and downlink (DL) transmission, namely, frequency division duplex (FDD) and time division duplex (TDD).

[0041] Although the functionality described herein may be performed in fixed and / or wireless network nodes in various example embodiments, in other example embodiments, the functionality may be implemented in a user equipment device (such as a cellular phone or a tablet computer or a laptop computer or a desktop computer or a mobile IoT device or a fixed IoT device). This user equipment device may, for example, be appropriately equipped with corresponding capabilities, as described in conjunction with fixed and / or wireless network nodes. The user equipment device may be a user device and / or a control device, such as a chipset or a processor, which is configured to control the user device when installed therein. Examples of such functionality include boot server functionality and / or a home subscriber server, which may be implemented by providing software to the user equipment device, the software being configured to cause the user equipment device to perform from the perspective of these functions / nodes.

[0042] In order to allow simultaneous DL and UL transmission on PRBs within an unpaired wideband of an NR cell, a combination of TDD and FDD is proposed, which can be referred to as a subband non-overlapping full-duplex (SBFD) scheme. In SBFD, at least a portion of the resources configured for DL ​​transmission in the time domain can be dynamically or semi-statically assigned to UL transmission. In other words, the SBFD frame is a form of UL-DL PRB segmentation.

[0043] To implement SBFD frames, there are several challenges. First, the location and size of such UL-DL subbands may not be fixed, so the UE needs to know the time and frequency location of the subbands to be used for SBFD operation with the gNB. Therefore, signaling of SBFD frame configuration is required.

[0044] Backward compatibility with gNBs or UEs that only support normal TDD or FDD operation needs to be ensured. A gNB or corresponding cell supporting SBFD operation is expected to coexist with other gNBs or cells that only support normal TDD operation, both from a co-channel (i.e., cells deployed on the same carrier frequency, e.g., belonging to the same operator) and adjacent channel (i.e., cells deployed on adjacent carrier frequencies, e.g., belonging to different operators) perspective. In addition, existing 5G UEs that cannot be upgraded to support SBFD-specific features can be served on cells supporting SBFD without experiencing performance degradation, e.g., compared to the performance of normal TDD cells.

[0045] To address the above and other potential problems, embodiments of the present disclosure provide solutions for SBFD frame structures and related configurations. The configuration of UL-DL PRB splitting is flexible, i.e., the location and size of UL-DL resources or subbands can be configured, for example, at the cell level or operator level, or can even change over time in each individual cell. To this end, the gNB enables one or more signalings for configuring UL-DL PRB splitting, for example, by configuring, activating or deactivating one or more UL subbands. In addition, by allocating different subband configurations to TDD mode 1 and mode 2, asymmetric SBFD subframe configurations are possible. In some example embodiments of the present disclosure, the terms "UL-DL PRB splitting" and "UL subband" may be used interchangeably.

[0046] Figure 1 1 shows an example network system 100 in which example embodiments of the present disclosure may be implemented. Figure 1 As shown, the communication network 100 may include a first device 110 and a second device 120. The first device 110 may be a terminal device (e.g., UE). The second device 120 may be a network device (e.g., gNB) serving terminal device, for example, the first device 110 located in the cell 102. Hereinafter, the first device 110 may also be referred to as UE 110, and the second device 120 may also be referred to as gNB 120.

[0047] The first device 110 and the second device 120 may communicate with each other based on a normal FDD scheme, a normal TDD scheme, or a SBFD scheme. In the context of the present disclosure, the SBFD scheme may be referred to as a cross-division duplex (xDD) scheme, a flexible duplex (FDU) scheme, etc. A link from the first device 110 to the second device 120 is referred to as UL, and a link from the second device 120 to the first device 110 is referred to as DL.

[0048] In TDD, the second device 120 may indicate the configuration of the TDD-UL-DL mode to the first device 110. Specifically, the second device 120 may configure or indicate a unit time resource (e.g., symbol or time slot) as "DL" or "UL" or "flexible" via RRC configuration. There is a common mode, which is broadcast as part of the system information in TDD-UL-DL-ConfigCommon and is received by all UEs in the cell 102 accordingly.

[0049] Figure 2A and Figure 2B An example configuration of a TDD mode suitable for an embodiment of the present disclosure is shown. Figure 2A As shown, TDD-UL-DL mode 200 is configured via TDD-UL-DL-ConfigCommon, which can be mode 1 or mode 2. Figure 2B As shown, TDD-UL-DL mode 202 is configured via TDD-UL-DL-ConfigCommon, which can be two cascaded modes, namely, both mode 1 and mode 2 repeated in the time domain. The PRBs of the symbols have the same characteristics, "D" for DL, "F" for flexible, and U for UL. The configured mode includes a DL phase at the beginning and a UL phase at the end, and the middle part is designated as "flexible". The flexible symbols are intended to be used for UL or DL ​​at the right time, which may depend on the gNB decision, by either Dynamically schedule a UE to send UL transmissions or receive DL transmissions using scheduling downlink control information (DCI) (e.g., DCI format 0_x for UL, DCI format 1_x for DL, where x represents 0, 1, or 2), ● Additional UE-specific configuration signaling is provided semi-statically via Radio Resource Control (RRC) in TDD-UL-DL-ConfigDedicated, which also specifies some or all flexible symbols of TDD-UL-DL-ConfigCommon as DL or UL, • Send DCI format 2_0 (ie, SFI), which specifies the "flexible" symbols left after the generic RRC configuration and the dedicated RRC configuration as DL or UL.

[0050] In some example embodiments, the second device 120 may indicate a UL-DL partition or subband configuration to the first device 110. This allows some resources that were originally allocated as DL or flexible to be converted to UL. In the context of the present disclosure, UL-DL partition refers to at least a set of UL resources or subbands (e.g., REs, PRBs) that are converted from a set of DL and flexible symbols to a set of resource elements that can be used for UL transmissions. In the SBFD scheme, SBFD UL subbands are created on DL (and possibly flexible) symbols within the full carrier or BWP bandwidth. In this way, dynamic adjustment of the subband configuration, for example according to business needs, can be supported.

[0051] It should be understood that, hereinafter, the embodiments may be described in conjunction with the TDD scheme, however, the SBFD frame configuration and UL-DL partitioning provided in the present disclosure are also applicable to the FDD scheme. Therefore, the present disclosure is not limited in this regard.

[0052] It should also be understood that Figure 1 The number of network devices and terminal devices shown in FIG. 1 is given for illustrative purposes and does not imply any limitation. Communication network 100 may include any suitable number of network devices and terminal devices.

[0053] Depending on the communication technology, the communication network 100 can be a code division multiple access (CDMA) network, a time division multiple access (TDMA) network, a frequency division multiple access (FDMA) network, an orthogonal frequency division multiple access (OFDMA) network, a single carrier frequency division multiple access (SC-FDMA) network, or any other network. The communication discussed in the network 100 may conform to any suitable standard, including but not limited to new radio (NR) access, long term evolution (LTE), LTE evolution, advanced LTE (LTE-A), wideband code division multiple access (WCDMA), code division multiple access (CDMA), cdma2000, and global system for mobile communications (GSM), etc. In addition, the communication 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. The technology described herein can be used for the above-mentioned wireless networks and radio technologies as well as other wireless networks and radio technologies. For clarity, certain aspects of the techniques are described below for LTE, and LTE terminology is used in much of the description below.

[0054] The following will refer to Figures 3 to 8 The principles and embodiments of the present disclosure are described in detail. Figure 3 FIG. 3 is a signaling diagram showing an example process 300 for frequency time resource configuration according to some example embodiments of the present disclosure. The process 300 may involve: Figure 1 The first device 110 and the second device 120 are shown. For discussion purposes, the process 300 will be referred to as Figure 1 describe.

[0055] As an example, the process 300 may be implemented in a scenario where the first device 110 and the second device 120 communicate in FDD or TDD mode. In the process 300, the second device 120 sends 305 first configuration information indicating a set of resources for TDD or FDD communication between the first device 110 and the second device 120. The set of resources may include a first subset of resources for uplink transmission.

[0056] For example, the first configuration information may be a TDD-UL-DL-mode indicated via TDD-UL-DL-ConfigCommon. TDD-UL-DL-ConfigCommon may be included in an RRC system information broadcast (SIB). In the case of TDD, the set of resources may be symbols or time slots allocated for DL ​​and UL transmission in the TDD-UL-DL-mode, and the first subset of resources may be UL symbols or time slots.

[0057] In some cases, the second device 120 may transmit TDD-UL-DL-ConfigDedicated (eg, DDDDU) in addition to TDD-UL-DL-ConfigCommon to maintain backward compatibility.

[0058] The second device 120 sends 310 indicating second configuration information indicating at least one second subset of resources for uplink transmission. In this case, the at least one second subset of resources is configured as UL-DL partitioning and includes at least one resource in addition to the first subset of resources. The second configuration information can be included in, for example, a SIB, an RRC message, etc.

[0059] In the context of the present disclosure, a first subset of resources may refer to at least one UL time slot or symbol in one or more TDD-UL-DL modes. A second subset of resources may refer to one or more subbands that are allocated for UL transmission in at least one DL (or flexible) time slot or symbol in one or more TDD-UL-DL modes. As an example, a total of 4 subbands (e.g., SBFD_UL_subband1, ..., SBFD_UL_subband4) may be configured, where SBFD_UL_subband1 is allocated to TDD mode 1, and SBFD_UL_subband1 and SBFD_UL_subband3 are allocated to TDD mode 2, i.e., the same subband may be allocated to one or more TDD modes, and not all subbands need to be allocated to one or more TDD modes.

[0060] In some example embodiments, the first subset of resources may not overlap with at least one second subset of resources. Alternatively, in some other embodiments, at least part of the first subset of resources may overlap with at least one second subset of resources. Therefore, the scope of the present disclosure is not limited in this regard.

[0061] Reference now FIG. 4A to FIG. 4C SBFD resource configuration according to an embodiment of the present disclosure is described. It should be understood that the resource units in the time domain and the frequency domain are given for the purpose of illustration and do not imply the classification method of the first type of classification model. Figure 4A In the example shown in FIG. 4E , the time resource unit may be a symbol or a time slot, and the frequency resource unit may be a subcarrier, however, any other resource unit or resolution may also be applicable to the implementation of SBFD resource configuration.

[0062] In some example embodiments, the second configuration information may include: - a first indication of a starting frequency resource and a starting time resource of one of at least one second subset of resources, and - A second indication of an ending frequency resource and an ending time resource for a second subset of resources.

[0063] To this end, the second configuration information may be in the form of a two-tuple, ie, [symbol, PRB], for respectively indicating the starting position and the ending position of each UL subband. Figure 4A A schematic diagram of an example configuration 400 of UL subbands according to some example embodiments of the present disclosure is shown. As indicated by a first configuration indication, time slots 401 to 404 are allocated for DL ​​transmission, while time slot 405 is allocated for UL transmission. A second configuration indication may indicate UL-DL partitions 406 and 407 corresponding to subband 1 and subband 2 for UL transmission, which are shown as RE / symbol rectangles.

[0064] The position and size of each of the UL-DL partitions 406 and 407 can be determined based on the start and end points of the corresponding subband in the time domain and the frequency domain (i.e., the two opposite vertices of the RE / symbol rectangle). Accordingly, the start position and the end position of UL subband 1 can be indicated by [first time index, first frequency index] and [second time index, second frequency index], respectively. The start position and the end position of UL subband 2 can be indicated in a similar manner.

[0065] In some example embodiments, the second configuration information may include a starting frequency resource and a starting time resource for one of at least one second subset of resources, a first number of frequency resources in the second subset, and a second number of time resources in the second subset. Figure 4B A schematic diagram of an example configuration 410 of UL subbands according to some example embodiments of the present disclosure is shown. Similar to configuration 400, as indicated by the first configuration information, time slots 401 to 404 are allocated for DL ​​transmission, while time slot 405 is allocated for UL transmission. The second configuration indication may indicate UL-DL partitions 406 and 407 corresponding to subband 1 and subband 2 for UL transmission, which are shown as RE / symbol rectangles.

[0066] The position and size of each of the UL-DL partitions 406 and 407 may be determined based on the starting point of the corresponding subband in the time domain and the frequency domain and the bandwidth and duration of the subband. Accordingly, the starting position of UL subband 1 may be indicated by [first time index, first frequency index]. The bandwidth may be indicated by the number of frequency resources (e.g., PRBs) in the frequency domain, and the duration may be indicated by the number of time resources (e.g., symbols, time slots, etc.) in the time domain.

[0067] In some example embodiments, the at least one second subset of resources may include a first target subset of resources and a second target subset of resources. In these embodiments, the second configuration information may include: ● a third indication of a starting frequency resource and a starting time resource for the first target subset of resources, and a first bandwidth of a first uplink subband corresponding to the first target subset of resources; - A fourth indication of a starting frequency resource and a starting time resource for a second target subset of resources, and a second bandwidth of a second uplink subband corresponding to the second target subset of resources.

[0068] In the above case, the start time resource of the second target resource subset may be before the first symbol after the end time resource of the first target resource subset in the time domain. Figure 4CA schematic diagram of an example configuration 420 of UL subbands according to some example embodiments of the present disclosure is shown. Similar to configurations 400 and 410, time slots 401 to 404 are allocated for DL ​​transmission, while time slot 405 is allocated for UL transmission, as indicated by the first configuration information. The second configuration indicates UL-DL partition 406 and partition 407 corresponding to subband 1 and subband 2 for UL transmission.

[0069] like Figure 4C As shown, each of subband 1 and subband 2 is indicated by a starting PRB and a starting symbol and a bandwidth. The starting PRB and the starting symbol can be indicated by [first time index, first frequency index]. Using the starting PRB and the bandwidth, the frequency domain allocation of each subband can be determined. For time domain allocation, it is assumed that the last symbol of the last subband (i.e., subband 2) is fixed in the time domain, for example, it can be designated as the last DL symbol in the S slot, or the last symbol in the S slot, etc. Therefore, the last symbol of any other subband (i.e., subband 1) is the starting symbol of the next subband (i.e., subband 2). In this way, the time domain allocation of each subband can be derived based on the configured starting symbol of each subband.

[0070] In some example embodiments, the second configuration information may include: - a first resource indicator value (RIV) indicating a starting frequency resource and a number of frequency resources in one of at least one second subset of resources; and - A second RIV indicating a starting time resource and a duration of the time resource in a second subset of resources.

[0071] In the above embodiments, the frequency-time grid corresponding to the UL-DL partition is indicated in a similar manner to provide physical uplink shared channel (PUSCH) resource allocation. The RIV jointly provides the starting PRB and the number of PRBs within the active bandwidth part (BWP) or within the common RB (CRB) grid. In addition, the corresponding start and length indicator value (SLIV) jointly provides the starting position and duration within the TDD-UL-DL mode.

[0072] In some example embodiments, the first device 110 may determine 315 a third subset of resources based on the first configuration information and the second configuration information, the third subset of resources comprising the first subset of resources and the second subset of resources. Based on the received information, the UE is able to determine a corresponding UL or DL ​​direction or UL-DL partition for each resource in the time and frequency grid, which will be described later in conjunction with Fig. 6A was discussed.

[0073] Thus, the first device 110 may send a data transmission 320 to the second device 120 on the third subset of resources.

[0074] Semi-static signaling of SBFD configuration has been described above. In the following, dynamic signaling of SBFD configuration will be discussed in detail, which can be used together with semi-static signaling. In this case, the second configuration information may at least indicate the frequency domain allocation of at least one second subset of resources. The second device 120 may also send 325 to the first device 110 a configuration message for indicating activation or deactivation of at least one second subset of resources in the frequency domain. The configuration message may be sent via low-layer signaling (e.g., DCI, media access control (MAC) control element (CE)).

[0075] In some example embodiments, such a configuration message may be used to activate or deactivate each of the subbands corresponding to the at least one second subset of resources.

[0076] In the above embodiment, after receiving the configuration message, the first device 110 can determine 330 whether the configuration message includes a first indication to activate at least a first part of at least one second subset of resources, or a second indication to deactivate at least a second part of at least one second subset of resources.

[0077] If the configuration message includes the first indication, the first device 110 may determine a third subset of resources allocated for uplink transmission based on the first indication. In this case, the third subset of resources may include the first subset of resources and at least a first portion of at least one second subset of resources. Thus, the first device 110 may send a data transmission 335 to the second device 120 on the third subset of resources.

[0078] Otherwise, if the configuration message includes the second indication, the first device 110 may determine a fourth subset of resources allocated for uplink transmission based on the second indication. In this case, the fourth subset of resources may include the first subset of resources and the remaining portion of at least one second subset of resources except for at least the second portion. Therefore, the first device 110 may send 340 to the second device 120.

[0079] For frequency domain allocation, the second configuration information may include a starting frequency resource and a bandwidth of an uplink subband corresponding to one of at least one second subset of resources. Alternatively, the second configuration information may include a starting frequency resource and an ending frequency resource of an uplink subband corresponding to the second resource subset. For time domain allocation, the first configuration information may indicate a TDD-UL-DL mode for the first device 110. In addition, the configuration message may include an indication of an uplink subband applied to at least one time slot of the TDD-UL-DL mode.

[0080] In some example embodiments, the indication may be a bitmap indicating the D slots and / or S slots on which the TDD-UL-DL mode of the configured or active UL subbands is applied. In the case where multiple UL subbands are to be applied, an indication of the active subbands is required, which will be discussed later. In this case, it is assumed that the UL resources start from the first symbol of each indicated slot, or alternatively, the starting symbol of the first indicated slot may be configured and the indicated other slots convert all DL and / or flexible symbols to SBFD symbols.

[0081] In some example embodiments, the bitmap has a number of bits corresponding to the number of D slots and S slots in the TDD-UL-DL mode. For example, for the TDD-UL-DL mode "DDDSU", the bitmap for indicating the active subband applies to the second D slot and the third D slot, and the S slot may be 0111.

[0082] Figure 5A Schematic diagram showing an example configuration 500 of UL subbands according to some example embodiments of the present disclosure. Figure 5A As shown, time slots 501 to 504 are allocated for DL ​​transmission, while time slot 505 is allocated for UL transmission, as indicated by the first configuration information. The second configuration information indicates the frequency domain allocation of UL-DL partitions 506 to 508.

[0083] Taking UL-DL split 506 as a representative, the second configuration information may indicate the starting position and bandwidth of the corresponding subband 1. For example, the starting PRB may be indicated by a first time index. In addition, the bandwidth may be indicated by the number of frequency resources (e.g., PRBs) in the frequency domain. Additionally or alternatively, in some embodiments, the second configuration information may further indicate the starting symbol of the first time slot of UL-DL separation 506 to 508 (i.e., UL-DL separation 506), and full time slot allocation is assumed for the remaining UL-DL separations 506 to 508.

[0084] Alternatively, to reduce the number of bits required for the bitmap, a table may be specified or configured for each TDD mode to indicate only the relevant possibilities of using active UL subbands in the time domain. In this way, the gNB can change the SBFD configuration in the time domain in a dynamic and flexible manner.

[0085] For example, the mapping of a 2-bit bitmap with the TDD-UL-DL mode "DDDSU" is shown in Table 1. It should be understood that this method is also applicable to the case where more than one TDD-UL-DL mode is configured. Table 1: Example of a 2-bit bitmap for TDD-UL-DL mode "DDDSU"

[0086] Alternatively, in another example configuration of the UL subbands, at least two non-overlapping UL subbands may be configured for a SBFD frame having the same bandwidth and time domain allocation, such as a nominal time domain allocation. One of the UL subbands is separated from the other by an offset in the frequency domain. In this case, the second configuration information may indicate a starting time resource and a starting frequency resource (e.g., in the form of [first time index, first frequency index]) and a frequency offset for one of the UL subbands. Thus, the position of the other subband may be determined based on the frequency offset.

[0087] Figure 5B FIG. 5 is a schematic diagram showing another example configuration 510 of UL subbands according to some example embodiments of the present disclosure. Figure 5B As shown, as indicated by the first configuration information, time slots 511 to 514 are allocated for DL ​​transmission, while time slot 515 is allocated for UL transmission. Two non-overlapping UL subbands 1 and UL subband 2 with the same bandwidth and nominal time domain allocation are configured for the SBFD frame. UL subband 2 is separated from UL subband 1 by a frequency offset, which may be an offset for frequency hopping.

[0088] Additionally, in some example embodiments, for each time instance (e.g., time slot, symbol, etc.), only one of UL subband 1 and UL subband 2 may be used. This facilitates UL transmission and DL reception filtering at the UE side. The second device 120 may dynamically indicate which subband is active for the UL, and the reference point for frequency domain allocation is after the activated subband.

[0089] Additionally or alternatively, in the case where frequency hopping is enabled, the two subbands 1 and 2 may be used alternately in the time domain. The starting frequency hopping is on the activated subbands indicated independently. Furthermore, in the case where more than two UL subbands are configured, the indication of which two of the more than two subbands will be used for frequency hopping should also be indicated dynamically or semi-statically.

[0090] In some example embodiments, the TDD-UL-DL mode RRC configuration element may be extended to include one or more UL subbands for the corresponding TDD-UL-DL mode. This allows an "asymmetric" SBFD subframe configuration to be implemented by assigning different subband configurations (e.g., DXXXU-DDDXU) to TDD Mode 1 and TDD Mode 2. Fig. 6A A schematic diagram is shown of an example allocation 600 of UL sub-bands to a TDD-UL-DL mode according to some example embodiments of the present disclosure.

[0091] like Fig. 6AAs shown, TDD mode 1 "DDDSU" corresponding to time slots 601 to 605 is cascaded to TDD mode 2 "DDSUU" corresponding to time slots 606 to 610. At least one set of UL subbands 1 and 3 may overlap with DL, UL, or flexible symbols in the time domain. DL symbols / time slots overlapping with at least one UL subband set may be considered as SBFD symbols / time slots. This may be considered as an RRC or higher layer configured SBFD UL-DL mode, which may be used for the purpose of initial access (e.g., random access channel), as well as for determining the validity of certain semi-static signals (e.g., physical downlink control channel (PDCCH), channel state information reference signal (CSI-RS), etc.).

[0092] To allow dynamic adaptation of SBFD subband configuration, multiple UL subbands may be configured via high-layer indications (e.g., RRC signaling), and low-layer indications (e.g., MAC CE or new DCI format) may be used to dynamically activate or deactivate one or more UL subbands. For example, the DCI or MAC CE may provide a bitmap, e.g., 10011, to activate or deactivate each of the subbands.

[0093] Note that not all UL subbands need to be allocated to the TDD-UL-DL mode provided by RRC / SIB, as lower layer signaling (e.g., via MAC, DCI, etc.) may also be used to determine which UL subbands should be considered valid or activated by the UE at a certain time.

[0094] Figure 6B Schematic diagram showing an example configuration 610 for dynamic activation or deactivation of UL subbands according to some example embodiments of the present disclosure. Figure 6B As shown, the first device 110 receives a configuration message for changing the UL subband configuration via low-layer signaling (eg, MAC, DCI, etc.). Figure 6B In the example, the MAC or DCI includes a bitmap of “011”.

[0095] Accordingly, the first device 110 applies the received UL subband configuration after a predetermined time from receiving the configuration message. Therefore, in time slots 621 to 625, subbands 2 and 3 are deactivated and subband 1 is activated, and in time slots 626 to 630, the states of subbands 1 to subband 3 are switched, that is, subbands 2 and 3 are activated and subband 1 is deactivated.

[0096] In some example embodiments, a new MAC CE or DCI format may be used to activate or deactivate each of the subbands. For example, the DCI or MAC CE provides a bitmap, e.g., 0110, where each bit is mapped to a corresponding one of the four (pre)configured UL subbands. As an option, '1' and '0' may be used to indicate which UL subbands should be considered enabled and disabled, respectively. As another option, the switching of the '1' value corresponds to the activation / deactivation state of the subband, in other words, it is used to switch the state of the subband from enabled to disabled or from disabled to enabled.

[0097] It should be understood that other options with a mix of high-level signaling and low-level signaling may also be used to implement embodiments. For example, a table with multiple possible enabled or disabled states (e.g., 0101, 0111, 0000, 1010) may be provided via RRC signaling, and a 2-bit indication in a DCI or MAC CE points to one of the 4 entries in the table. Therefore, the present disclosure is not limited thereto.

[0098] In some example embodiments, a method similar to that used to dynamically signal the use of an SFI for DCI format 2_0 with dynamic TDD may be reused for SBFD operation. In this case, the frequency domain allocation for DU segmentation is configured via high-level signaling (e.g., RRC, MAC, etc.). The time granularity for indicating SBFD operation may be at the OFDM symbol level. One or more time slot format tables are configured at the first device 110, indicating multiple options for UL-DL resource segmentation with a time resolution of one OFDM symbol. For example, to this end, a table similar to Table 11.1.1-1 in TS38.213 may be used, in which the "F" symbol is replaced with the "SBFD" symbol.

[0099] Instead of using a new table, a subset of unused indices 66-254 of Table 11.1.1-1 in TS 38.213 may be used for signaling of SBFD symbols, e.g., indices 60-115 may be used to signal the same slot format as indices 0-55, but with "SBFD" symbols replacing "F" symbols. In some embodiments, the gNB may send one DCI 2_0 per cell. UEs that do not support SBFD operation interpret the 'F' symbol as a flexible symbol according to Table 11.1.1-1 in TS 38.213, while SBFD-aware UEs interpret the 'F' symbol as a SBFD symbol with frequency domain UL-DL partitioning configured by higher layers. In addition, in some cases, SBFD-aware UEs may also be configured via higher layer signaling to interpret the 'F' symbol as a flexible symbol or a SBFD symbol according to Table 11.1.1-1 in TS 38.213.

[0100] Alternatively, in some other embodiments, the gNB may configure UEs that do not support SBFD operation and UEs that support SBFD via two separate DCI 2_0. In this case, the SFI is signaled separately to UEs that do not support SBFD operation and UEs that are aware of SBFD. The index may point to two different tables, i.e., Table 11.1.1-1 in TS 38.213 for UEs that do not support SBFD operation and a new table for UEs that are aware of SBFD, or to the same extended table 11.1.1-1 in TS 38.213.

[0101] An example of a slot format that may be used for SBFD operation is shown in Table 2. For example, one entry may be defined as D, X2, X2, X2, U, U, X3, X3, X3, X3, X3, U, U, U, where Xn represents a SBFD symbol with UL-DL partitioning in the frequency domain as configured in SBFD_UL_subband_n. Table 2: Timeslot formats available for SBFD operations

[0102] It should be understood that some steps in process 200 are optional or can be omitted, and the order of the steps is given for illustrative purposes. Therefore, the embodiments of the present disclosure are not limited in this regard.

[0103] According to an exemplary embodiment of the present disclosure, a scheme for SBFD frame structure and related configuration is provided. The configuration of UL-DL splitting and UL subband is flexible, that is, the location and size of UL-DL PRB splitting can be configured at, for example, cell level or operator level, or can even change over time in each individual cell. To this end, the gNB enables one or more signalings for configuring, activating or deactivating UL-DL PRB splitting. In addition, asymmetric SBFD subframe configuration is achieved by allocating TDD mode 1 and mode 2 with different subband configurations.

[0104] Figure 7 A flowchart of an example method 700 according to some example embodiments of the present disclosure is shown. The method 700 may be performed on a terminal device (e.g., referring to Figure 1 For the purpose of discussion, reference will be made to Figure 1 Method 700 is described.

[0105] At 710, the first device 110 receives first configuration information from the second device 120, the first configuration information indicating a set of resources for time division duplex communication or frequency division duplex communication between the first device 110 and the second device 120. The set of resources may include a first subset of resources for uplink transmission.

[0106] At 720, the first device 110 receives second configuration information indicating at least one second subset of resources for uplink transmission from the second device 120. The at least one second subset of resources may include at least one resource other than the first subset of resources.

[0107] In some example embodiments, the first subset of resources may not overlap with the at least one second subset of resources. Additionally or alternatively, at least a portion of the first subset of resources may overlap with the at least one second subset of resources.

[0108] In some example embodiments, the second configuration information may include: - a first indication of a starting frequency resource and a starting time resource of a second subset of at least one second subset of resources, and - A second indication of an ending frequency resource and an ending time resource for a second subset of resources.

[0109] In some example embodiments, the second configuration information may include a starting frequency resource and a starting time resource of a second subset of at least one second subset of resources, a first number of frequency resources in the second subset, and a second number of time resources in the second subset.

[0110] In some example embodiments, the at least one second subset of resources may include a first target subset of resources and a second target subset of resources. In this case, the second configuration information may include: - a third indication of a starting frequency resource and a starting time resource for a first target subset of resources and a first bandwidth of a first uplink subband corresponding to the first target subset of resources; - a fourth indication of a starting frequency resource and a starting time resource for a second target subset of resources and a second bandwidth of a second uplink subband corresponding to the second target subset of resources; Additionally, in these embodiments, the start time resource of the second target subset of resources may be the first symbol after the end time resource of the first target subset of resources in the time domain.

[0111] In some example embodiments, the second configuration information may include: - a first resource indicator value indicating a starting frequency resource and a number of frequency resources of a second subset of at least one second subset of resources; and - A second resource indicator value indicating a starting time resource and a duration of the time resource for a second subset of resources.

[0112] In some example embodiments, the second configuration information may be included in one of a system information block (SIB) or a radio resource control (RRC) message.

[0113] In some example embodiments, first device 110 may determine a third subset of resources based on the first configuration information and the second configuration information, the third subset including the first subset of resources and the second subset of resources. First device 110 may then send a data transmission to second device 120 on the third subset of resources.

[0114] In some example embodiments, the second configuration information may indicate at least one second subset of resources in the frequency domain.First device 110 may receive a configuration message from second device 120, the configuration message indicating at least one second subset of resources in the time domain.

[0115] Additionally or alternatively, in the above embodiment, the second configuration information includes one of the following: ● a starting frequency resource and a bandwidth of an uplink subband corresponding to one of at least one second subset of resources, or • The starting frequency resource and the ending frequency resource of the uplink subband corresponding to the second subset of resources.

[0116] In some example embodiments, the first configuration information may indicate a time division duplex mode for the first device 110. The configuration message may include an indication that at least one time slot of the time division duplex mode applies an uplink subband.

[0117] Additionally or alternatively, in the above embodiments, the indication may be a bitmap having a number of bits corresponding to a number of at least one of the following: ● Multiple downlink time slots or symbols in time division duplex mode, or ● At least one special time slot or symbol in time division duplex mode. In this case, the first value of the bit in the bitmap may indicate that the corresponding time slot or symbol applies an uplink subband corresponding to one of the at least one second subset of resources. Additionally or alternatively, the second value of the bit in the bitmap may indicate that the corresponding time slot or symbol does not apply an uplink subband.

[0118] In some example embodiments, the multiple values ​​of the bitmap may indicate multiple combinations of at least one of the following for which uplink subbands are applied: ● Multiple downlink time slots or symbols in time division duplex mode, or ● At least one special time slot or symbol in time division duplex mode. In this case, mapping of the plurality of values ​​to the plurality of combinations may be preconfigured or predetermined at the first device 110 and the second device 120 .

[0119] In some example embodiments, the starting time resource of the second subset of resources may be the first symbol of the corresponding time slot indicated by the bitmap.

[0120] In some example embodiments, the starting time resource of the first second subset in the second subset may be indicated by the second device 120. Further, the starting time resources of the remaining second subsets in the second subset may be the first symbol of the corresponding time slot indicated by the bitmap.

[0121] In some example embodiments, the second configuration information may indicate a first target subset and a frequency offset of resources in the time domain. The first device 110 may determine at least one second target subset of resources based on the first target subset and the frequency offset of resources in the time domain. In this case, the first target subset of resources may correspond to a first uplink subband. Additionally or alternatively, at least one second target subset of resources may correspond to at least one second uplink subband.

[0122] In some example embodiments, the frequency offset may correspond to frequency hopping associated with the first device 110. The first uplink sub-band and the at least one second uplink sub-band may also be applied alternately in the time domain.

[0123] In some example embodiments, the first configuration information may indicate a first time division duplex mode and a second time division duplex mode for first device 110. Additionally or alternatively, the second configuration message may include at least one first uplink subband allocated to the first time division duplex mode and at least one second uplink subband allocated to the second time division duplex mode.

[0124] In some example embodiments, the second configuration information may indicate at least one second subset of resources in the frequency domain. In this case, the first device 110 may receive a DCI from the second device 120, the DCI including an SFI corresponding to at least one second subset of resources in the time domain. The first device 110 may determine a third subset of resources allocated for uplink transmission based on the slot format indicator. In this case, the third subset of resources may include the first subset of resources and at least one second subset of resources. Therefore, the first device may send a data transmission to the second device 120 on the third subset of resources.

[0125] In some example embodiments, first device 110 may receive a configuration message from second device 120. If the configuration message includes a first indication of activating at least a first portion of at least one second subset of resources, first device 110 may determine a third subset of resources allocated for uplink transmission based on the first indication. The third subset of resources may include the first subset of resources and at least a first portion of at least one second subset of resources. First device 110 may then send a data transmission to second device 120 on the third subset of resources.

[0126] Otherwise, in some example embodiments, if the configuration message includes a second indication to deactivate at least a second portion of at least one second subset of resources, the first device 110 may determine a fourth subset of resources allocated for uplink transmission based on the second indication. The fourth subset of resources may include the first subset of resources and the remaining portion of at least one second subset of resources other than at least the second portion. The first device 110 may then send a data transmission to the second device 120 on the fourth subset of resources.

[0127] In some example embodiments, the configuration message may include a DCI, a MAC CE, or the like.

[0128] In some example embodiments, the first device 110 may include a terminal device, and the second device 120 may include a network device. Alternatively, in some other embodiments, the first device 110 may include a network device, and the second device 120 may include a terminal device.

[0129] Figure 8 A flowchart of an example method 800 according to some example embodiments of the present disclosure is shown. The method 800 may be performed on a network device (e.g., referring to Figure 1 For the purpose of discussion, reference will be made to Figure 1 Method 800 is described.

[0130] At 810, the second device 120 sends first configuration information to the first device 110, the first configuration information indicating a set of resources for time division duplex communication or frequency division duplex communication between the first device 110 and the second device 120. The set of resources may include a first subset of resources for uplink transmission.

[0131] At 820 , the second device 120 sends second configuration information to the first device 110 , the second configuration information indicating at least one second subset of resources for uplink transmission, the at least one second subset of resources including at least one resource other than the first subset of resources.

[0132] In some example embodiments, the first subset of resources may not overlap with the at least one second subset of resources. Additionally or alternatively, at least a portion of the first subset of resources may overlap with the at least one second subset of resources.

[0133] In some example embodiments, the second configuration information may include: - a first indication of a starting frequency resource and a starting time resource of a second subset of at least one second subset of resources, and - A second indication of an ending frequency resource and an ending time resource for a second subset of resources.

[0134] In some example embodiments, the second configuration information may include a starting frequency resource and a starting time resource of one of at least one second subset of resources, a first number of frequency resources of the second subset, and a second number of time resources of the second subset.

[0135] In some example embodiments, the at least one second subset of resources may include a first target subset of resources and a second target subset of resources. In this case, the second configuration information may include: ● a third indication of a first bandwidth of a first uplink subband corresponding to the first target subset of resources and a starting frequency resource and a starting time resource of the first target subset of resources; and ● a fourth indication of a second bandwidth of a second uplink subband corresponding to the second target subset of resources and a starting frequency resource and a starting time resource of the second target subset of resources; Additionally, in these embodiments, the start time resource of the second target subset of resources may be the first symbol after the end time resource of the first target subset of resources in the time domain.

[0136] In some example embodiments, the second configuration information may include: - a first resource indicator value indicating a starting frequency resource and a number of frequency resources of a second subset of at least one second subset of resources; and - A second resource indicator value indicating a starting time resource and a duration of the time resource in a second subset of resources.

[0137] In some example embodiments, the second configuration information may be included in one of a system information block (SIB) or a radio resource control (RRC) message.

[0138] In some example embodiments, the second device 120 may receive the data transmission from the first device 110 on a third subset of resources, the third subset of resources comprising the first subset of resources and the second subset of resources.

[0139] In some example embodiments, the second configuration information may indicate at least one second subset of resources in the frequency domain.The second device 120 may send a configuration message to the first device 110, the configuration message indicating at least one second subset of resources in the time domain.

[0140] In some example embodiments, the second configuration information may include one of the following: ● a starting frequency resource and a bandwidth of an uplink subband corresponding to one of at least one second subset of resources; or • The starting frequency resource and the ending frequency resource of the uplink subband corresponding to the second subset of resources.

[0141] In some example embodiments, the first configuration information may indicate a time division duplex mode for the first device 110, and the configuration message includes an indication that at least one time slot of the time division duplex mode applies an uplink subband.

[0142] In some example embodiments, the indication may be a bitmap having a number of bits corresponding to the number of at least one of: ● Multiple downlink time slots or symbols in time division duplex mode, or ● At least one special time slot or symbol in time division duplex mode. In this case, the first value of the bit in the bitmap may indicate that the time slot or symbol applies an uplink subband corresponding to one of the at least one second subset of resources. Additionally or alternatively, the second value of the bit in the bitmap may indicate that the corresponding time slot or symbol does not apply an uplink subband.

[0143] In some example embodiments, the multiple values ​​of the bitmap may indicate multiple combinations of at least one of the following for which uplink subbands are applied: ● Multiple downlink time slots or symbols in time division duplex mode, or ● At least one special time slot or symbol in time division duplex mode. In this case, mapping of the plurality of values ​​and the plurality of combinations may be preconfigured or predetermined at the first device 110 and the second device 120 .

[0144] In some example embodiments, the starting time resource of the second subset of resources may be the first symbol of the corresponding time slot indicated by the bitmap.

[0145] In some example embodiments, the starting time resource of the first second subset in the second subset may be indicated by the second device 120. Further, the starting time resources of the remaining second subsets in the second subset may be the first symbol of the corresponding time slot indicated by the bitmap.
