Abstract
Description
[Technical Field]
[0001] FIELD Embodiments of the present disclosure relate generally to the field of telecommunications, and more particularly to a device, method, apparatus, and computer-readable storage medium for frame structure configuration enhancements. [Background technology]
[0002] In communication systems, two main duplexing modes are used for uplink (UL) and downlink (DL) transmission: frequency division duplexing (FDD) and time division duplexing (TDD). In FDD, paired bands are used for simultaneous DL and UL transmission, with a guard band between them. In TDD, unpaired bands are used, and resources are divided in the time domain into different symbols or slots for DL and UL transmission, respectively. Allocating a time slot for UL in TDD reduces coverage and capacity and increases latency.
[0003] Against this background, an evolution of duplexing is proposed for 5G New Radio (NR) that enables simultaneous DL and UL transmissions on different physical resource blocks (PRBs) within the unpaired band of a cell. Summary of the Invention

[0027] To enable simultaneous DL and UL transmissions on PRBs within unpaired widebands in an NR cell, a combination of TDD and FDD has been proposed, sometimes referred to as subband non-overlapping full duplex (SBFD). In SBFD, at least a portion of the resources configured for DL transmission in the time domain may be dynamically or semi-statistically allocated to UL transmission. In other words, the SBFD frame takes the form of a UL-DL PRB split.
[0028] Implementing SBFD frames faces several challenges. First, the location and size of these UL-DL subbands may not be fixed, so the UE needs to communicate with the gNB the time and frequency location of the subbands to use for SBFD operation. Therefore, signaling of the SBFD frame configuration is required.
[0029] Backward compatibility with gNBs or UEs that only support normal TDD or FDD operation must be ensured. A gNB or corresponding cell that supports 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. Furthermore, existing 5G UEs that cannot be upgraded to support SBFD-specific features can be served by SBFD-enabled cells without experiencing performance degradation compared to their performance in normal TDD cells, for example.
[0030] To solve these and other potential problems, embodiments of the present disclosure provide a SBFD frame structure and related configuration solution. The configuration of UL-DL PRB splitting is flexible; that is, the location and size of UL-DL resources or subbands may be configured, for example, at the cell level or operator level, or may be changed over time in individual cells. To this end, one or more signaling signals are enabled by the gNB to configure the UL-DL PRB split, for example, by configuring (activating or deactivating) one or more UL subbands. Furthermore, asymmetric SBFD subframe configurations are also possible by assigning TDD Pattern 1 and Pattern 2 with different subband configurations. In some exemplary embodiments of the present disclosure, the terms “UL-DL PRB splitting” and “UL subband” may be used interchangeably.
[0031] 1 illustrates an exemplary network system 100 in which exemplary embodiments of the present disclosure may be implemented. As illustrated in FIG. 1, 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., a UE). The second device 120 may be a terminal device, for example, a network device (e.g., a gNB) that provides service to the first device 110 located within a cell 102. Hereinafter, the first device 110 may also be referred to as a UE 110, and the second device 120 may also be referred to as a gNB 120.
[0032] The first device 110 and the second device 120 can communicate with each other based on a conventional FDD scheme, a conventional TDD scheme, or an SBFD scheme. In the context of this disclosure, the SBFD scheme may also be referred to as a cross-division duplex (xDD) scheme, a flexible duplex (FDU) scheme, etc. The link from the first device 110 to the second device 120 is referred to as an UL, and the link from the second device 120 to the first device 110 is referred to as a DL.
[0033] In TDD, the second device 120 can instruct the first device 110 to configure a TDD-UL-DL-pattern. In particular, the second device 120 can configure or instruct a unit time resource (e.g., symbol or slot) as "DL" or "UL" or "flexible" via RRC configuration. There is a common pattern that is broadcast as part of the system information of TDD-UL-DL-ConfigCommon and received by all UEs in the cell 102 accordingly.
[0034] 2A and 2B illustrate example configurations of TDD patterns suitable for embodiments of the present disclosure. As shown in FIG. 2A, TDD-UL-DL-pattern 200 is configured via TDD-UL-DL-ConfigCommon, which can be either Pattern 1 or Pattern 2. As shown in FIG. 2B, TDD-UL-DL-pattern 202 is configured via TDD-UL-DL-ConfigCommon, and two concatenated patterns, i.e., both Pattern 1 and Pattern 2, may be repeated in the time domain. The PRBs of the symbols have the same string: "D" for DL, "F" for flexible, or "U" for UL. The configured pattern includes a DL phase first and a UL phase last, with the remaining phase in between designated "flexible." This flexible symbol is intended to be opportunistically used for either UL or DL and can be subject to the gNB's decision to either: Scheduling downlink control information (DCI), for example DCI format 0_x for UL and DCI format 1_x for DL (where x denotes 0, 1 or 2), is used to dynamically schedule UL transmission or DL reception to the UE. Additional UE-dedicated configuration signaling is provided semi-statically via Radio Resource Control (RRC) in TDD-UL-DL-ConfigDedicated to further designate some or all flexible symbols in TDD-UL-DL-ConfigCommon as DL or UL. Transmit DCI format 2_0 (i.e., SFI) and further designate the "flexible" symbols remaining after the common and dedicated RRC configurations as DL or UL.
[0035] In some exemplary embodiments, the second device 120 can instruct the first device 110 on a UL-DL split or subband configuration. This allows a portion of resources originally allocated as DL or flexible to be converted to UL. In the context of this disclosure, a UL-DL split 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 include a set of resource elements usable for UL transmission. In an 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 to, for example, traffic demands is supported.
[0036] Although embodiments may be described below in conjunction with a TDD system, it should be understood that the SBFD frame structure and UL-DL splitting provided in this disclosure are also applicable to an FDD system, and thus the disclosure is not limited in this respect.
[0037] It should also be understood that the number of network devices and terminal devices shown in Figure 1 is given for illustrative purposes, without implying any limitation, and communication network 100 may include any suitable number of network devices and terminal devices.
[0038] Depending on the communication technology, communication network 100 may 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 others. Communications discussed in network 100 may conform to any suitable standard, including, but not limited to, New Radio Access (NR), Long Term Evolution (LTE), LTE Evolution, LTE Advanced (LTE-A), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access (CDMA), cdma2000, Global System for Mobile Communications (GSM), and the like. Furthermore, communications may be performed according to any generation of communication protocols now known or 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, and fifth generation (5G) communication protocols. The technology described herein can be used with the wireless networks and technologies listed above, as well as other wireless networks and technologies. For clarity, one aspect of the technology will be described below in terms of LTE, and LTE terminology will be used in much of the description below.
[0039] The principles and embodiments of the present disclosure are described in detail below with reference to Figures 3 to 8. Figure 3 is a signaling chart illustrating an example process 300 for frequency-time resource configuration in some exemplary embodiments of the present disclosure. The process 300 may include a first device 110 and a second device 120, as shown in Figure 1. For illustrative purposes, the process 300 will be described with reference to Figure 1.
[0040] As an example, process 300 may be implemented in a scenario in which first device 110 and second device 120 communicate in an FDD or TDD mode. In process 300, second device 120 transmits first configuration information 305 indicating a set of resources for TDD or FDD communication between first device 110 and second device 120. The set of resources may include a first subset of resources for uplink transmission.
[0041] For example, the first configuration information may be a TDD-UL-DL-pattern indicated via TDD-UL-DL-ConfigCommon, which may be included in an RRC system information broadcast (SIB). In the case of TDD, the set of resources may be symbols or slots for DL and UL transmissions allocated in the TDD-UL-DL-pattern, and the first subset of resources may be UL symbols or slots.
[0042] In some cases, in addition to TDD-UL-DL-ConfigCommon, to maintain backward compatibility, the second device 120 may send TDD-UL-DL-ConfigDedicated, e.g., DDDDU.
[0043] The second device 120 transmits second configuration information 310 indicating at least a second subset of resources for uplink transmission, where the at least one second subset of resources is configured as a UL-DL split and includes at least one resource other than the first subset of resources. The second configuration information may be included, for example, in a SIB, an RRC message, etc.
[0044] In the context of the present disclosure, a first subset of resources may refer to at least one UL slot or symbol in one or more TDD-UL-DL patterns. A second subset of resources may refer to one or more subbands allocated for UL transmission in at least one DL (or flexible) slot or symbol in one or more TDD-UL-DL patterns. As an example, a total of four subbands, e.g., SBFD_UL_subband1,...,SBFD_UL_subband4, are configured, where SBFD_UL_subband1 is allocated to TDD pattern 1 and SBFD_UL_subband1 and SBFD_UL_subband3 are allocated to TDD pattern 2. That is, the same subband can be allocated to one or more TDD patterns; it is not necessary for all subbands to be allocated to one or more TDD patterns.
[0045] In 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 a portion of the first subset of resources may overlap with at least one second subset of resources. Accordingly, the scope of the present disclosure is not limited in this respect.
[0046] 4A to 4C, an SBFD resource configuration according to an embodiment of the present disclosure will now be described. It should be understood that the resource units in the time domain and frequency domain are given for illustrative purposes without implying the classification approach of the first type classification model. In the examples shown in FIGS. 4A to 4E, the unit of the time resource may be a symbol or a slot, and the unit of the frequency resource may be a subcarrier, but any other resource unit or resolution may also be suitable for implementing the SBFD resource configuration.
[0047] In an exemplary embodiment, the second setting information is a first indication of a starting frequency resource and a starting time resource of the at least a second subset of resources; a second indication of an ending frequency resource and an ending time resource of the second subset of resources; may include:
[0048] Thus, the second configuration information may be in the form of a two-tuple [symbol, PRB] to indicate the start and end positions of each of the UL subbands, respectively. Figure 4A shows a schematic diagram of an example UL subband configuration 400 in some example embodiments of the present disclosure. As indicated by the first configuration instruction, slots 401 through 404 are allocated for DL transmission, and slot 405 is allocated for UL transmission. The second configuration instruction may indicate UL-DL splits 406 and 407, corresponding to subband 1 and subband 2 for UL transmission, which are indicated by RE / rectangle symbols.
[0049] The location and size of each UL-DL split 406 and 407 may be determined based on the start and end points of the corresponding subband in both the time and frequency domains, i.e., the two opposite corners of the RE / rectangular symbol. Thus, the start and end positions of UL subband 1 may be denoted by [first time index, first frequency index] and [second time index, second frequency index], respectively. The start and end positions of UL subband 2 may be denoted similarly.
[0050] In some exemplary embodiments, the second configuration information may include a starting frequency resource and a starting time resource 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 shows a schematic diagram of an exemplary configuration 410 of UL subbands in some exemplary embodiments of the present disclosure. Similar to configuration 400, slots 401 through 404 are allocated for DL transmissions and slot 405 is allocated for UL transmissions, as indicated by the first configuration information. The second configuration instruction indicates UL-DL splits 406 and 407, corresponding to subband 1 and subband 2 for UL transmission, indicated by RE / rectangle symbols.
[0051] The location and size of each of the UL-DL splits 406 and 407 may be determined based on the starting location of the corresponding subband in both the time domain and the frequency domain, as well as the bandwidth and duration of the subband. Thus, the starting location 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, slots, etc.) in the time domain.
[0052] In some exemplary 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 start frequency resource and a start time resource of the first target subset of resources and a first bandwidth of the first uplink subband corresponding to the first target subset of resources; a fourth indication of a start frequency resource and a start time resource of the second target subset of resources and a second bandwidth of the second uplink subband corresponding to the second target subset of resources; and may include:
[0053] In the above case, 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. Figure 4C shows a schematic diagram of an example UL subband configuration 420 in accordance with some exemplary embodiments of the present disclosure. Similar to configurations 400 and 410, slots 401 to 404 are allocated for DL transmission, and slot 405 is allocated for UL transmission, as indicated by the first configuration information. The second configuration instruction indicates UL-DL splits 406 and 407 corresponding to subband 1 and subband 2 for UL transmission.
[0054] As shown in FIG. 4C, each of subbands 1 and 2 is indicated by a starting PRB, a starting symbol, and a bandwidth. The starting PRB and starting symbol can be represented as [first time index, first frequency index]. The frequency domain allocation of each subband can be determined based on the starting PRB and bandwidth. Regarding the time domain allocation, the last symbol of the last subband (i.e., subband 2) is assumed to be fixed in the time domain. For example, a specific symbol can be designated as the last DL symbol of S slots or the last symbol of S slots. Therefore, the last symbol of another subband (i.e., subband 1) becomes 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 set starting symbol of each subband.
[0055] In an exemplary embodiment, the second setting information is a first resource index value (RIV) indicating an origination frequency resource and a number of frequency resources in one of the at least one second subset of resources; a second RIV indicating start times and durations of temporal resources in the second subset of resources; may include:
[0056] In the above embodiments, the frequency-time square corresponding to the UL-DL split is shown in a similar way to provide the 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 Common RB (CRB) grid. Furthermore, the corresponding Start and Length Indicator Value (SLIV) jointly provides the starting position and duration within the TDD-UL-DL-pattern.
[0057] In some demonstrative embodiments, the first device 110 may determine a third subset of resources 315 including the first and second subsets of resources based on the first and second configuration information. Based on the received information, the UE may determine a respective UL or DL direction or UL-DL split for each resource in the time and frequency grid described below in connection with FIG. 6A.
[0058] Accordingly, the first device 110 may send 320 a data transmission to the second device 120 on the third subset of resources.
[0059] Semi-statistical signaling of SBFD configuration has been described above. Dynamic signaling of SBFD configuration is described in detail below, which can be used in conjunction with semi-statistical signaling. In this case, the second configuration information may indicate at least a frequency domain allocation of at least a second subset of resources. The second device 120 may further transmit a configuration message 325 to the first device 110 to indicate activation or deactivation of at least a second subset of resources in the time domain. The configuration message may be transmitted by lower layer signaling, such as DCI, medium access control (MAC) control element (CE), etc.
[0060] In some exemplary embodiments, such a configuration message may be used to activate or deactivate each of the individual subbands corresponding to at least a second subset of resources.
[0061] In the above embodiment, after receiving the configuration message, the first device 110 may determine (330) whether the configuration message includes a first instruction to activate at least a first portion of at least one second subset of resources or a second instruction to deactivate at least a second portion of at least one second subset of resources.
[0062] If the configuration message includes the first instruction, the first device 110 may determine a third subset of the allocated resources for uplink transmission based on the first instruction. In this case, the third subset of resources may include the first subset of resources and at least an initial portion of at least one second subset of resources. Accordingly, the first device 110 may send a data transmission to the second device 120 on the third subset of resources (335).
[0063] Otherwise, if the configuration message includes the second instruction, the first device 110 may determine a fourth subset of the allocated resources for uplink transmission based on the second instruction. In this case, the fourth subset of resources may include the first subset of resources and a remaining portion other than at least the second portion of the at least one second subset of resources. Accordingly, the first device 110 may transmit to the second device 120 (340).
[0064] In the case of a frequency domain assignment, the second configuration information may include a starting frequency resource and a bandwidth of an uplink subband corresponding to one of the 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 subset of resources. In the case of a time domain assignment, the first configuration information may indicate a TDD-UL-DL pattern of the first device 110. Furthermore, the configuration message may include an indication of at least one slot of the TDD-UL-DL pattern to which the uplink subband should be applied.
[0065] In some exemplary embodiments, the indication may be a bitmap to indicate the D and / or S slots of the TDD-UL-DL pattern in which the configured or active UL subbands are applied. In case of multiple applied UL subbands, an indication of the active subbands is required, as will be described later. In this case, the UL resources start from the first symbol of each indicated slot, or alternatively, the starting symbol of the first indicated slot is set, and the other indicated slots are assumed to translate all DL symbols and / or flexible symbols as SBFD symbols.
[0066] In some exemplary embodiments, the bitmap has a number of bits corresponding to the number of D and S slots in the TDD-UL-DL-pattern. As an example, for the TDD-UL-DL-pattern "DDDSU", the bitmap may be 0111 to indicate that the active subbands are applicable to the second and third D and S slots.
[0067] 5A illustrates a schematic diagram of an exemplary UL subband configuration 500 in accordance with some exemplary embodiments of the present disclosure. As illustrated in FIG. 5A, slots 501 through 504 are allocated for DL transmissions and slot 505 is allocated for UL transmissions, as indicated by first configuration information. A second configuration instruction indicates the frequency domain allocation of UL-DL splits 506 through 508.
[0068] Representing the UL-DL split 506, 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. Furthermore, 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 slot in the UL-DL split 506-508 (i.e., the UL-DL split 506), with full slot allocation assumed for the remainder of the UL-DL split 506-508.
[0069] Alternatively, to reduce the number of bits required in the bitmap, a table can be identified or configured for each TDD pattern that shows only the relevant possibilities for using active UL subbands in the time domain. In this way, the gNB can dynamically and flexibly change the SBFD configuration in the time domain.
[0070] For example, the mapping between a 2-bit bitmap and the TDD-UL-DL-pattern "DDDSU" is shown in Table 1. It should be understood that such an approach is also applicable when multiple TDD-UL-DL-patterns are configured.
[0071] [Table 1]
[0072] Alternatively, in another example of a UL subband configuration, at least two non-overlapping UL subbands may be configured for the SBFD frame, and these subbands have the same bandwidth and time domain allocation, e.g., a nominal time domain allocation. One of the UL subbands is separated from the other UL subband by a frequency domain offset. In this case, the second configuration information may indicate the starting time resource and starting frequency resource of one of the UL subbands (e.g., in the format of [first time index, first frequency index]) and the frequency offset. Thus, the location of the other subband can be determined based on the frequency offset.
[0073] 5B shows a schematic diagram of another exemplary configuration 510 of UL subbands in some exemplary embodiments of the present disclosure. As shown in FIG. 5B, slots 511 through 514 are allocated for DL transmission, and slot 515 is allocated for UL transmission as indicated by the first configuration information. Two non-overlapping UL subbands 1 and 2 having 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 due to frequency hopping.
[0074] Furthermore, in some exemplary embodiments, for each time instance (e.g., slot, symbol, etc.), only one of UL subbands 1 and 2 can be used. This is beneficial for UL transmit and DL receive filtering at the UE side. The second device 120 can dynamically indicate which subbands are active for UL, and the reference point for frequency domain allocation follows the activated subband.
[0075] Additionally or alternatively, if frequency hopping is enabled, the two subbands 1 and 2 can be used alternately in the time domain. The start of the frequency hop is on the active subband, which is indicated independently. Furthermore, if two or more UL subbands are configured, the indication of which two of the two or more subbands to use for frequency hopping should also be indicated dynamically or semi-statically.
[0076] In example embodiments, the TDD-UL-DL-pattern RRC configuration element can be extended to include one or more UL subbands that apply to the corresponding TDD-UL-DL-pattern. This allows for implementing an "asymmetric" SBFD subframe configuration by allocating TDD Pattern 1 and TDD Pattern 2 with different subband configurations, such as DXXXU-DDDXU. Figure 6A is a schematic diagram illustrating an example of allocation 600 of UL subbands to TDD-UL-DL patterns, in accordance with some example embodiments of the present disclosure.
[0077] As shown in FIG. 6A, TDD pattern 1 "DDDSU" corresponding to slots 601 through 605 is concatenated with TDD pattern 2 "DDSUU" corresponding to slots 606 through 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 / slots that overlap with at least one set of UL subbands can be considered SBFD symbols / slots. This can be considered an SBFD UL-DL pattern configured by RRC or higher layers that can be used for purposes of initial access (e.g., random access channel) and determining the validity of certain semi-static signals, such as the physical downlink control channel (PDCCH) and channel state information reference signal (CSI-RS).
[0078] To enable dynamic adaptation of the SBFD subband configuration, multiple UL subbands may be configured via higher layer indication (e.g., RRC signaling), while lower layer indication (e.g., MAC CE or a new DCI format) may be used to activate or deactivate one or more UL subbands in a dynamic manner, e.g., the DCI or MAC CE may provide a bitmap, e.g., 10011, to activate or deactivate each individual subband.
[0079] It should be noted that not all UL subbands need to be assigned to the TDD-UL-DL-pattern provided by the RRC / SIB, as lower layer signaling (via MAC, DCI, etc.) may also be used to determine which UL subbands are enabled / active for the UE at a given time.
[0080] 6B shows a schematic diagram of an example configuration 610 for dynamic activation or deactivation of UL sub-bands in some example embodiments of the present disclosure. As shown in FIG. 6B, the first device 110 receives a configuration message via lower layer signaling, e.g., MAC, DCI, etc., to change the configuration of the UL sub-bands. In the example of FIG. 6B, the MAC or DCI includes the bitmap "011."
[0081] Therefore, the first device 110 applies the received UL subband configuration after a predetermined time from receiving the configuration message. Thus, in slots 621-625, subbands 2 and 3 are deactivated and subband 1 is activated, and in slots 626-630, the states of subbands 1-3 are toggled, i.e., subbands 2 and 3 are activated and subband 1 is deactivated.
[0082] In some exemplary embodiments, a new MAC CE or DCI format may be used to activate or deactivate each individual subband. For example, the DCI or MAC CE provides a bitmap, e.g., 0110, with each bit mapped to a corresponding one of four (pre-)configured UL subbands. Optionally, "1" and "0" can be used to indicate which UL subbands are considered enabled and disabled, respectively. Another option is to use a value of "1" to toggle the activation / deactivation state of the corresponding subband, in other words, to switch the state of a subband from enabled to disabled or from disabled to enabled.
[0083] It should be appreciated that other options for mixing higher and lower layer signaling are possible to implement embodiments. For example, a table with multiple possible enabled or disabled states, e.g., 0101, 0111, 0000, 1010, may be provided through RRC signaling, and a two-bit indication in the DCI or MAC CE may point to one of four entries in the table. Thus, the present disclosure is not limited in this respect.
[0084] In some exemplary embodiments, a similar approach to that used to dynamically signal SFI using DCI format 2_0 in dynamic TDD may be reused for SBFD operation. In this case, the frequency domain allocation of DU splits is configured via higher layer signaling (e.g., RRC, MAC, etc.). The time granularity for indicating SBFD operation may be at the OFDM symbol level. One or more tables of slot formats are configured in the first device 110 to indicate multiple options for UL-DL resource partitioning with a time resolution of one OFDM symbol. For example, a table similar to Table 11.1.1-1 of TS 38.213 in this embodiment may be used for this purpose, where the "F" symbol is replaced with the "SBFD" symbol.
[0085] Instead of using a new table, a subset of unused indices 66-254 in Table 11.1.1-1 of TS 38.213 can be used to signal SBFD symbols. For example, indices 60-115 can be used to signal the same slot format as indices 0-55, but the "F" symbol can be replaced with an "SBFD" symbol. In some embodiments, a gNB can transmit 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 of TS 38.213, while SBFD-capable UEs interpret the "F" symbol as an SBFD symbol with frequency-domain UL-DL splitting configured by higher layers. Additionally, in some cases, SBFD-capable UEs can be further configured by higher layer signaling whether to interpret the "F" symbol as a flexible symbol or an SBFD symbol according to Table 11.1.1-1 of TS 38.213.
[0086] Alternatively, in some other embodiments, the gNB can configure UEs that do not support SBFD operation and SBFD-capable UEs via two separate DCI 2_0. In this case, the SFI is signaled separately to UEs that do not support SBFD operation and SBFD-capable UEs. The indexes either point to two different tables, i.e., Table 11.1.1-1 of TS 38.213 for UEs that do not support SBFD operation and a new table for SBFD-capable UEs, or point to the same extended Table 11.1.1-1 of TS 38.213.
[0087] Examples of slot formats available for SBFD operation are shown in Table 2. For example, one entry can be defined as D, X2, X2, X2, U, U, X3, X3, X3, X3, X3, U, U, U, where "Xn" indicates UL-DL split SBFD symbols in the frequency domain configured by SBFD_UL_subband_n.
[0088] [Table 2]
[0089] It should be understood that some of the steps in process 200 are optional or may be omitted, and the order of the steps is given for illustrative purposes, and thus, embodiments of the present disclosure are not limited in this respect.
[0090] According to an exemplary embodiment of the present disclosure, an SBFD frame structure and related configuration solution is provided. The UL-DL split and UL subband configuration are flexible; that is, the location and size of the UL-DL PRB split may be configured, for example, at the cell level or operator level, or may vary over time in individual cells. To this end, one or more signalings are enabled by the gNB to configure, activate, or deactivate the UL-DL PRB split. Furthermore, asymmetric SBFD subframe configurations are also possible by assigning TDD Pattern 1 and Pattern 2 with different subband configurations.
[0091] 7 shows a flowchart of an example method 700 in some example embodiments of the present disclosure. Method 700 can be implemented in a terminal device, for example, first device 110 described with reference to FIG. 1. For illustrative purposes, method 700 will be described with reference to FIG. 1.

In this case, the first value of the bit in the bitmap may indicate a corresponding slot or symbol to which an uplink subband corresponding to one of the at least one second subset of resources is applied, and additionally or alternatively, the second value of the bit in the bitmap may indicate a corresponding slot or symbol to which no uplink subband is applied.
[0105] In some exemplary embodiments, the values of the bitmap apply to uplink subbands: Multiple downlink slots or symbols in a time division duplex pattern, or at least one special slot or symbol in the time division duplex pattern; may represent at least one multiple combination of: In this case, the association of the multiple values and the multiple combinations may be pre-configured or pre-determined in the first device 110 and the second device 120.
[0106] In some example embodiments, the start time resource of the second subset of resources may be the first symbol of the corresponding slot indicated by the bitmap.
[0107] In some exemplary embodiments, the first one of the starting time resources of the second subset may be indicated by the second device 120. Additionally, the remaining starting time resources of the second subset may be the first symbols of the corresponding slots indicated by the bitmap.
[0108] In some exemplary embodiments, the second configuration information may indicate a first target subset of resources in the time domain and a frequency offset. The first device 110 may determine at least one second target subset of resources based on the first target subset of resources in the time domain and the frequency offset. In this case, the first target subset of resources may correspond to a first uplink subband. Additionally or alternatively, the at least one second target subset of resources may correspond to at least one second uplink subband.

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. Thus, the first device can transmit a data transmission to the second device 120 on the third subset of resources.
[0112] In some demonstrative embodiments, the first device 110 may receive a configuration message from the second device 120. If the configuration message includes a first instruction to activate at least a first portion of at least one second subset of resources, the first device 110 may determine a third subset of resources allocated for uplink transmission based on the first instruction. The third subset of resources may include the first subset of resources and at least a first portion of the at least one second subset of resources.
