Description

TECHNICAL FIELD

[0001] Various example embodiments of the present disclosure generally relate to the field of telecommunications, and in particular, to methods, devices, apparatuses, and computer-readable storage media for configuring a frame pattern in a sub-band non-overlapping full duplex (SBFD) scenario. BACKGROUND

[0002] Currently, New Radio (NR) supports two duplex modes: frequency division duplex (FDD) for paired bands and time division duplex (TDD) for unpaired bands. In TDD, time domain resources are divided between downlink (DL) and uplink (UL). The allocation of limited duration of uplink in TDD will result in reduced coverage, increased latency, and reduced capacity.

[0003] To address the above challenges, research has been initiated on the evolution of duplex operation in NR. SBFD has been proposed as a solution for enhanced duplex operation. In SBFD, simultaneous occurrence of DL transmission and UL reception on different physical resource blocks (PRBs) within an unpaired wideband NR cell is allowed. This duplex solution is also referred to as cross-split duplex (xDD) or flexible duplex (FDU). SUMMARY

[0030] As described above, techniques of SBFD have been proposed as a scheme of enhanced duplex operation. An example of a static TDD frame pattern in a cell bandwidth is shown as follows, e.g., DDDSU, where D, S, U respectively refer to DL slots, special slots, UL slots. In the special slots, there can be DL, UL, and gap symbols.

[0034] An example of SBFD frame pattern in one cell bandwidth is shown below, e.g., DUD with legacy frame structure DDDSU.

[0035] An example of SBFD frame pattern DUD with legacy frame structure DDDSU

[0036] In some embodiments, for a SBFD symbol configured semi-statically with DL in TDD-UL-DL-ConfigCommon For a SBFD-aware UE configured with UL subband in SBFD symbol configured as DL, UL transmission within the UL subband can be allowed in the symbol and UL transmission outside the UL subband can not be allowed in the symbol. In addition, in some embodiments, the frequency location of the DL subband(s) can be known to the SBFD-aware UE. In addition, the frequency location of the DL subband(s) can be explicitly indicated to the SBFD-aware UE or implicitly derived by the SBFD-aware UE.

[0037] In some embodiments, DL reception(s) within the DL subband can be allowed in the symbol. Note that in the symbol, UL transmission can be within the active UL BWP and DL reception can be within the active DL BWP.

[0038] In some embodiments, UL transmission and DL reception in SBFD symbols and non-SBFD symbols can be enhanced, such as physical downlink control channel (PDCCH), scheduled or configured physical uplink control channel (PUCCH), scheduled or configured physical uplink shared channel (PUSCH), scheduled or configured physical downlink shared channel (PDSCH), without repetition in SBFD symbols and non-SBFD symbols.

[0039] In addition, more enhancements can also be made to scheduled or configured sounding reference signal (SRS) / channel state information reference signal (CSI-RS), multiple PUSCH / PDSCH scheduled by a single downlink control information (DCI), TBoMS scheduled or configured TB processing, on SBFD symbols and non-SBFD symbols with or without repetition.

[0040] Additionally, further enhancements can be made to the scheduled or configured PDSCH, scheduled or configured PUSCH, and scheduled or configured PUCCH, which have repetitions on SBFD symbols and non-SBFD symbols.

[0041] In some embodiments, for in TDD-UL-DL-ConfigCommon The SBFD operation within a symbol is configured for flexibility, allowing UL transmission within a UL subband and disallowing UL transmission outside the UL subband within the symbol. The frequency locations of (multiple) DL subbands can be known to the UE through SBFD sensing. DL reception within (multiple) DL subbands can be allowed within the symbol. Furthermore, DL reception outside (multiple) DL subbands can be allowed or disallowed within the symbol.

[0042] In some embodiments, for in TDD-UL-DL-ConfigCommon The symbol is configured for flexible SBFD operation, which allows UL transmission within the UL subband within the symbol. From the gNB's perspective, resource blocks (RBs) outside the UL subband can be used in the symbol as UL or DL ​​exclusion guard bands (if used), and all of these RBs can be transmitted in the same direction.

[0043] In some embodiments, signaling for multiple guard bands may exist, and symbols may be converted to DL-only symbols. Additionally, in some embodiments, the frequency locations of the multiple DL subbands may be known to the SBFD-aware UE. DL reception within the multiple DL subbands may be permitted within the symbols.

[0044] In some embodiments, UL transmission can be within an active UL BWP, and DL reception can be within an active DL BWP in the symbol. For all RBs outside the UL subband, the SBFD-aware UE may not use separate RBs for DL ​​and UL simultaneously.

[0045] Although some discussion has been done on SBFD scenarios, there are still unresolved issues that require further discussion. One example unresolved issue is that traditional FDD and TDD resource allocation solutions are not applicable to SBFD scenarios, thus requiring new scheduling mechanisms, feedback mechanisms, and power control solutions.

[0046] Another example of an unresolved issue could be UL / DL conflict handling. Specifically, given the half-duplex limitation in the UE (while the gNB has full-duplex capability), new conflict scenarios between DL and UL can be identified, which requires the UE to have additional rules that prioritize the transmission / reception of one channel (PDSCH, PUSCH, PDCCH, PUCCH) over the other channel.

[0047] Another example pending issue can relate to dynamic TDD. Specifically, when dynamic TDD is used, flexible (F) slots / symbols can be configured in the frame structure, and all UEs in the same cell transmitting in the same symbol can be in the same transmission direction. In terms of radio resource configuration, it can be difficult to statically schedule resources for all UEs, which increases the complexity of radio resource management.

[0048] Furthermore, even though dynamic TDD can be considered by which the link direction of F slots is scheduled by DCI or changed using dynamic SFI, it can still have the drawback of requiring the corresponding slots / symbols to be configured as F, and thus there can be more uncertainty for the UE about how to handle, for example, semi-statically configured.

[0049] Another example pending issue can relate to TDD-UL-DL-ConfigDedicated . Specifically, TDD-UL-DL- ConfigDedicated It can be similar to the static TDD mode. In a network supporting SBFD, the UL and DL traffic ratio, UE mobility, and interference change will make such a static TDD structure inflexible. However, the reconfiguration method by RRC only can be too slow to cope with the fast-changing SBFD interference level. As a result, the communication performance can be significantly reduced.

[0050] In view of the above discussion, it is desirable to propose a more flexible solution for configuring frame patterns in the SBFD scenario.

[0051] According to the present disclosure, a first device (such as a terminal device) receives first information from a second device (such as a network device), where the first information indicates a first frame pattern in a set of preconfigured frame patterns. Furthermore, the first frame pattern is to be applied to a resource, and at least a part of the resource is an SBFD resource. Then, the first device communicates with the second device on the resource based at least in part on the first frame pattern.

[0052] According to the present disclosure, a set of frame patterns can be preconfigured. Based on the set of frame patterns, a frame pattern can be configured by the second device to a particular first device, and can also be dynamically updated by the second device. In this way, flexible frame pattern configuration can be achieved, and thus the first device can quickly respond to changes in interference, UL / DL traffic load, communication environment, function, traffic demand, etc.

[0053] Example Environment Figure 1AAn example communication environment 100A in which example embodiments of the present disclosure can be implemented is shown. The communication environment 100A can include a first device 110-1 and a second device 120. The communication environment 100A can also optionally include another first device 110-2. The first device 110-1 and the first device 110-2 can be referred to individually or jointly as the first device 110. The service area provided by the second device 120 is referred to as a cell. Furthermore, the second device 120 can provide one or more cells, for example, a cell 102 is provided by the second device 120, as Figure 1A shown.

[0054] In some example embodiments, the first device 110 can be included in a terminal device / apparatus, and the second device 120 can be included in a network device / apparatus serving the terminal device / apparatus.

[0055] Hereinafter, for the purpose of illustration, some example embodiments are described in which the first device 110 operates as a terminal device and the second device 120 operates as a network apparatus. However, in some example embodiments, operations described in connection with a terminal device can be implemented at a network apparatus or other apparatus, and operations described in connection with a network apparatus can be implemented at a terminal device or other apparatus.

[0056] In some example embodiments, if the first device 110 is a terminal device and the second device 120 is a network apparatus, a link from the second device 120 to the first device 110 is referred to as a downlink (DL), and a link from the first device 110 to the second device 120 is referred to as an uplink (UL). In the DL, the second device 120 is a transmitting (TX) device (or transmitter), and the first device 110 is a receiving (RX) device (or receiver). In the UL, the first device 110 is a TX device (or transmitter), and the second device 120 is an RX device (or receiver).

[0057] Communications in the communication environment 110A can be implemented according to any suitable communication protocol, including but not limited to cellular communication protocols of first generation (1G), second generation (2G), third generation (3G), fourth generation (4G), fifth generation (5G), sixth generation (6G), etc., wireless local area network communication protocols such as Institute of Electrical and Electronics Engineers (IEEE) 802.11, and / or any other protocol that is currently known or later developed. Moreover, communications can utilize any suitable wireless communication techniques, including but not limited to: code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), frequency division duplexing (FDD), time division duplexing (TDD), multiple-input multiple-output (MIMO), orthogonal frequency division multiple access (OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), and / or any other techniques that are currently known or later developed.

[0058] A variety of duplex modes can be supported in the communication environment 100A. Referring now to Figure 1B which shows a block 100B of three example duplex modes (i.e., TDD, FDD, and FDU such as SBFD).

[0059] FDD can be used for paired bands, and TDD can be used for unpaired bands. In TDD, time domain resources are divided between DL and UL. The allocation of limited duration of UL in TDD will result in reduced coverage, increased latency, and reduced capacity. SBFD can be considered as an evolution of duplex operation in NR. Specifically, SBFD can allow simultaneous occurring DL and UL transmissions on different physical resource blocks (PRBs) / sub-bands within an unpaired wideband NR cell, as Figure 1B illustrated.

[0060] In some embodiments, SBFD slots can include both SBFD symbols and non-SBFD symbols.

[0061] Moreover, different duplex modes can be used interactively. In view of this, there can be two types of resources for both DL and UL transmissions, namely: SBFD resources (such as slots, symbols) where both non-overlapping DL sub-bands and UL sub-bands exist, and non-SBFD resources (such as slots, symbols) where the entire band is used for either DL or UL (i.e., full DL / UL slots).

[0062] For better understanding, reference is now made to Figure 1C which shows a block 100C of SBFD resources and non-SBFD resources.

[0063] Operation and Example Signaling for Communication According to some example embodiments of the present disclosure, a solution of configuring frame pattern is provided. With the example embodiments discussed below, flexible frame pattern configuration can be achieved, and thus the first apparatus can quickly respond to changes of interference, UL / DL traffic load, communication environment, function, traffic demand, etc.

[0064] Reference is now made to Figure 2 which shows a signaling flow 200 of communication according to some embodiments of the present disclosure. For the purpose of discussion, reference will be made to Figures 1A-1C The signaling flow 200 is discussed, for example, by using the first apparatus 110-1 and the second apparatus 120 and optionally the first apparatus 110-2.

[0065] It should be appreciated that the operations at the first apparatus 110-1 / 110-2 and the second apparatus 120 should be coordinated. In other words, the second apparatus 120 and the first apparatus 110-1 / 110-2 should have a common understanding on the configuration, parameters, etc. This common understanding can be achieved through any suitable interaction between the second apparatus 120 and the first apparatus 110-1 / 110-2, or both the second apparatus 120 and the first apparatus 110-1 apply the same rules / policies.

[0066] In the following, although some operations are described from the perspective of the first apparatus 110-1 / 110-2, it should be appreciated that corresponding operations should be performed by the second apparatus 120. Similarly, although some operations are described from the perspective of the second apparatus 120, it should be appreciated that corresponding operations should be performed by the first apparatus 110-1 / 110-2. Only for the sake of brevity, some identical or similar content is omitted here.

[0067] In addition, in the following description, examples of signaling types (such as “RRC signaling”, “MAC CE”, “DCI”, “Uplink Control Information (UCI)”) are only for the purpose of illustration, without implying any limitation. In other example embodiments, any suitable message type can be used for the interaction between the first apparatus 110-1 / 110-2 and the second apparatus 120.

[0068] For the sake of better understanding, in the example of Figure 2 the first apparatus 110-1 can operate as a terminal device, and the second apparatus 120 can operate as a network apparatus.

[0069] In operation, the first apparatus 110-1 receives 235 first information from the second apparatus 120, where the first information indicates a first frame pattern in a set of preconfigured frame patterns. Further, the first frame pattern is to be applied to a resource, and at least a portion of the resource is an SBFD resource.

[0070] Then, the first apparatus 110-1 communicates 240 with the second apparatus 120 on the resources based at least in part on the first frame pattern (i.e., performs the transmission).

[0071] In some example embodiments, the first frame pattern can correspond to a plurality of slots, and indicates whether a slot of the plurality of slots is an UL slot (U slot), a DL slot (D slot), a special slot (S slot), a flexible slot (F slot), or an SBFD slot (X slot).

[0072] In some examples, the first information can be sent via one of: an RRC signal, a MAC CE, or a DCI.

[0073] In some example embodiments, the second apparatus 120 can send dedicated signaling (e.g., based on a MAC CE) to indicate that the first apparatus 110-1 changes or otherwise adds one UE-specific TDD configuration.

[0074] Note that if the second apparatus 120 uses a MAC CE to inform the frame pattern, it is needed to provide the related RRC parameters (such as a set of pre-configured frame patterns) to the first apparatus 110-1 in advance.

[0075] In some example embodiments, the first frame pattern can be valid from a following frame or after a pre-configured time duration after receiving the first information.

[0076] Alternatively, in some example embodiments, the first frame pattern can be valid for a configured time period. Also, in some example embodiments, the first information can indicate the configured time period.

[0077] In some example embodiments, the first apparatus 110-1 can start working with the first frame pattern from a certain time point (such as a next frame). Further, the valid time period of the first frame pattern can be permanent or short-term (such as defined by a timer). Also, in some example embodiments, the first apparatus 110-1 can return to the common frame pattern if a length of time without traffic scheduling exceeds a threshold time or the timer expires.

[0078] In one example embodiment, the first apparatus 110-1 can operate with a common frame pattern (such as a cell-specific frame pattern DDDSU). The second apparatus 120 can send another frame pattern index (such as corresponding to frame pattern DSUUU, i.e., the first frame pattern) to the first apparatus 110-1 through a MAC CE, and then the first apparatus 110-1 can start working with the new frame pattern from a following frame (such as a next frame).

[0079] As another example embodiment, the first apparatus 110-1 can operate with a common frame pattern, such as a cell-specific frame pattern DDDSU. The second apparatus 120 can send another frame pattern index (e.g., corresponding to frame pattern DXXUU, i.e., a first frame pattern) to the first apparatus 110-1 by MAC CE. In this example, X slots can indicate SBFD slots, and X slots can be signaled as D / F in TDD-UL-DL-ConfigDedicated the middle of the frame, i.e., the symbol is a SBFD symbol, and the second apparatus 120 can use UE-specific signaling to indicate the symbol as D / U, e.g., by DCI. Next, the first apparatus 110-1 can work with the new frame pattern starting from a subsequent frame, such as the next frame.

[0080] In the following, more details will be discussed regarding the set of preconfigured frame patterns. In some example embodiments, the set of preconfigured frame patterns can be a default configuration. As one example, the set of preconfigured frame patterns can be pre-defined by a communication organization, such as 3GPP, or by a network operator or service provider. In this way, no additional signaling exchange between the first apparatus 110-1 or the second apparatus 120 is needed.

[0081] Alternatively, in some embodiments, the set of preconfigured frame patterns can be configured by the second apparatus 120, as described below.

[0082] In some example embodiments, the first apparatus 110-1 can receive 210 second information from the second apparatus 120. The second information can indicate the set of preconfigured frame patterns. For example, the first apparatus 110-1 can receive a configuration of the set of preconfigured frame patterns (sometimes also referred to as a pool of TDD frame patterns configuration, a pool of frame patterns, or a frame pattern pool) configured by the second apparatus 120.

[0083] In some example embodiments, the second information can include a set of identities of frame patterns, where each identity in the set of identities corresponds to a preconfigured frame pattern.

[0084] As one example, the pool of TDD frame patterns can be specified in a wireless specification, such as defined as a table format and can be indexed. For example, 4 bits represent 16 such configurations, i.e., a pool of 16 frame patterns.

[0085] Alternatively, and additionally, the second information can include the set of preconfigured frame patterns.

[0086] As one example, the pool of frame patterns can be indicated based on TDD-UL-DL-ConfigCommon In one example, the pool of frame patterns can include: Pattern 1, frame pattern DDDSU, Pattern 1-2, frame pattern DSSUU, Pattern 1-3, frame pattern SUUUU, Pattern 1-4, frame pattern DSUUU.

[0087] In some example embodiments, the first apparatus 110-1 can also receive the dedicated TDD configuration using TDD-UL-DL- ConfigDedicated Alternatively, the first apparatus 110-1 can receive a pointer pointing to one of the TDD frame pattern configurations in a signaled pool (which can be a newly introduced signaling). Then, the first apparatus 110-1 can determine the link direction of the symbols based on the TDD-UL-DL- ConfigDedicated (or the new signaling) and can determine the UL subband configuration and DL subband configuration in the symbols based on the subband configuration and / or the SFI.

[0088] An example configuration for a set of preconfigured frame patterns is shown as follows.

[0089] TDD-UL-DL-ConfigPool2 ::= SEQUENCE { referenceSubcarrierSpacing SubcarrierSpacing, pattern1-2 TDD-UL-DL-Pattern, } TDD-UL-DL-Pattern ::= SEQUENCE { dl-UL-TransmissionPeriodicity ENUMERATED {ms2p5}, nrofDownlinkSlots INTEGER (2), nrofDownlinkSymbols INTEGER (10), nrofUplinkSlots INTEGER (2), nrofUplinkSymbols INTEGRE (2), … TDD-UL-DL-ConfigPool3 ::= SEQUENCE { referenceSubcarrierSpacing SubcarrierSpacing, pattern1-3 TDD-UL-DL-Pattern, } TDD-UL-DL-Pattern : : = SEQUENCE{ dl-UL-TransmissionPeriodicity ENUMERATED{ms2p5}, nrofDownlinkSlots INTEGER(0), nrofDownlinkSymbols INTEGER(10), nrofUplinkSlots INTEGER (4), nrofUplinkSymbols INTEGER (2), … TDD-UL-DL-ConfigPool4 :: = SEQUENCE{ referenceSubcarrierSpacing SubcarrierSpacing, pattern1-4 TDD-UL-DL-Pattern, } TDD-UL-DL-Pattern : : = SEQUENCE{ dl-UL-TransmissionPeriodicity ENUMERATED {ms 2p5}, nrofDownlinkSlots INTEGER(1), nrofDownlinkSymbols INTEGER(10), nrofUplinkSlot INTEGER (3), nrofUplinkSymbols INTEGER (2), … SBFDslots_bitmap INTEGER(01110)----------1 mean SBFD slots,0 meannon-SBFD slots, bitmap length equal dl-UL-T ransmissionPeriodicity TDD-UL-DL-ConfigDedicated :: = SEQUENCE{…} Or TDD-UL-DL-ConfigPoolindex={1,2,3…maxNrofindex}.

[0090] In some example embodiments, the locations of the SBFD resources can also be indicated together with the set of preconfigured frame patterns. For example, the first apparatus 110-1 can understand that time slot #0 and time slot #4 are non-SBFD time slots, and time slots #1 to 3 are SBFD time slots.

[0091] In some example embodiments, the first information and the second information can be included in a common signal (e.g., one RRC signaling) or at least two different signals (e.g., one RRC signaling and one MAC CE / DCI). The present disclosure is not limited thereto.

[0092] More details on how the second apparatus 120 determines the first frame pattern will be discussed below. According to some example embodiments of the present disclosure, the second apparatus 120 can determine the first frame pattern based on one or more factors that can be associated with the first apparatus 110-1, the second apparatus 120, and / or the wireless communication environment. The second apparatus 120 can select one or more factors as needed to determine the first frame pattern for the first apparatus 110-1.

[0093] Some example factors will be discussed with reference to the following example embodiments. It should be appreciated that the following example factors are given for the purpose of illustration and without implying any limitations. The second apparatus 120 can determine an appropriate frame pattern based on any suitable factors. In addition, the following example factors and other suitable factors can be used individually or in combination. The present disclosure is not limited thereto.

[0094] In some example embodiments, the example factors associated with the second apparatus 120 can include, but are not limited to, a traffic load of a currently applied frame pattern of the second apparatus 120, a downlink buffer status of the second apparatus 120, and the like.

[0095] In some example embodiments, the factors associated with the first apparatus 110-1 can include, but are not limited to, a traffic load of the first apparatus 110-1, a communication environment condition or a functional requirement of the first apparatus 110-1, a communication capability of the first apparatus 110-1, a usage status of the first apparatus 110-1, and the like.

[0096] In some example embodiments, with reference to Figure 2 , the first apparatus 110-1 can transmit 215 third information to the second apparatus 120. The third information can be used to assist the second apparatus 120 to determine 230 the first frame pattern for the first apparatus 110-1.

[0097] In some example embodiments, the third information can be transmitted via one of: a radio resource control (RRC) signal, a channel state information (CSI) report, a cross link interference (CLI) report, an uplink control information (UCI) dedicated for carrying the fourth information, or a medium access control (MAC) control element (CE).

[0098] In some example embodiments, the functional requirement can be associated with a communication mode of the first apparatus 110-1, and the communication mode is one of: a power saving mode, a discontinuous reception (DRX) mode, a connected mode, an idle mode, an inactive mode, or a small data transmission (SDT) mode.

[0099] In some example embodiments, the communication capability of the first apparatus 110-1 can be associated with at least one of: at least one frame pattern supported by the first apparatus 110-1, a first time period required for the first apparatus 110-1 to switch from uplink transmission to downlink transmission, or a second time period required for the first apparatus 110-1 to switch from downlink transmission to uplink transmission.

[0100] In some example embodiments, the communication environment status of the first apparatus 110-1 can comprise at least one of: a cell coverage status of the first apparatus 110-1, a path loss status of the first apparatus 110-1, an interference status of the first apparatus 110-1, or a signal quality measured by the first apparatus 110-1.

[0101] In some example embodiments, the usage status of the first apparatus 110-1 can be associated with at least one of: a device temperature of the first apparatus 110-1, a power consumption status of the first apparatus 110-1, or a battery usage status of the first apparatus 110-1.

[0102] Alternatively or in addition, the factor for determining the first frame structure can be represented by / included in a channel state information (CSI) report, a cross link interference (CLI) report, or other measurement report.

[0103] In this way, the second apparatus 120 can determine an appropriate frame pattern for the first apparatus 110-1. Specifically, for a particular first apparatus device, a cell-specific TDD / SBFD frame structure configuration (i.e., a common frame pattern) can be reserved, and a UE-specific TDD configuration can be dynamically modified based on, for example, a traffic load, a channel condition, etc. of the first apparatus 110-1.

[0104] Alternatively or additionally, the first apparatus 110-1 can report a desired / preferred / recommended frame pattern (hereinafter referred to as a second frame pattern) to the second apparatus 120. The second apparatus 120 can also take into account the reported second frame pattern when determining the first frame pattern for the first apparatus 110-1.

[0105] In some example embodiments, the first apparatus 110-1 can determine 220 the second frame pattern from a set of preconfigured frame patterns, and send 225 fourth information indicating the second frame pattern to the second apparatus 120.

[0106] In some example embodiments, the fourth information is sent via one of: an RRC signal, a channel state information (CSI) report, a cross-link interference (CLI) report, an uplink control information (UCI) dedicated to carrying the second frame pattern, or a MAC CE.

[0107] In one example embodiment, the second frame pattern can be reported together with a CSI or CLI report, or be considered as new UCI information reported in layer 1, e.g., via PUCCH or PUSCH. Alternatively, in another example embodiment, the second frame pattern can be reported in a MAC CE.

[0108] Similar to the second apparatus 120, the first apparatus 110-1 can also determine the second frame pattern based on one or more relevant factors. Some example embodiments on how to determine the second frame pattern will be discussed below. It should be appreciated that although the following example embodiments are discussed with reference to the first apparatus 110-1, the same or similar operations can also be performed by the second apparatus 120 when determining the first frame pattern.

[0109] In some example embodiments, the first apparatus 110-1 can determine the second frame pattern based on at least one of: a traffic load of the first apparatus 110-1, a communication environment condition of the first apparatus 110-1, a functional requirement of the first apparatus 110-1, a communication capability of the first apparatus 110-1, or a usage status of the first apparatus 110-1.

[0110] The physical meaning of these factors has been discussed sufficiently in the foregoing. Only the same or similar content is omitted for brevity. Details on how to determine an appropriate frame pattern based on example factors will be discussed below.

[0111] In some example embodiments, the first apparatus 110-1 can determine the second frame pattern based on a traffic load of the first apparatus 110-1.

[0112] As an example, the first apparatus 110-1 can select a semi-TDD frame pattern based on a current traffic load model. In one example, when the traffic load of the first apparatus 110-1 is low, the first apparatus 110-1 can determine a common TDD frame pattern. Further, when the traffic load of the first apparatus 110-1 changes, the first apparatus 110-1 can determine a new semi-TDD frame pattern accordingly.

[0113] In some example embodiments, the first apparatus 110-1 can select a semi-TDD frame pattern based on a current environmental condition and / or a transmit power state of the first apparatus 110-1.

[0114] In one example embodiment, if the first apparatus 110-1 is in an UL coverage enhancement mode, the first apparatus 110-1 can use a frame pattern DUUUU. In another example embodiment, if the path loss is large and the power headroom of the first apparatus 110-1 is low, the first apparatus 110-1 can use a UL reframe pattern.

[0115] In another example embodiment, if the first apparatus 110-1 operates in an interference mode, the first apparatus 110-1 can use a common frame pattern, such as frame pattern DDDSU.

[0116] In another example embodiment, if the first apparatus 110-1 operates in a UE-to-UE interference mode, the first apparatus 110-1 can use the same frame pattern as another inter-cell first apparatus.

[0117] In another example embodiment, the first apparatus 110-1 can measure an interference condition in a full band, all time slots, and then the first apparatus 110-1 can select a proper frame pattern matching that can be fed back to the second apparatus 120 as a preferred frame pattern.

[0118] In some example embodiments, the first apparatus 110-1 can determine a second frame pattern based on a functional requirement of the first apparatus 110-1.

[0119] In one example embodiment, if the first apparatus 110-1 is in a power saving mode, the first apparatus 110-1 can use a frame pattern DUUUU.

[0120] In another example embodiment, if the first apparatus 110-1 is in a DRX mode, the first apparatus 110-1 can use a frame pattern DUUUU.

[0121] In another example embodiment, if the first apparatus 110-1 is in an SDT mode in an inactive mode, the first apparatus 110-1 can use a frame pattern DDDSU that can be received from RRC release.

[0122] In some example embodiments, the first device 110-1 may determine the second frame pattern based on the communication capabilities of the first device 110-1 (such as at least one frame pattern supported by the first device 110-1, a first time period required for the first device 110-1 to switch from uplink transmission to downlink transmission, or a second time period required for the first device 110-1 to switch from downlink transmission to uplink transmission). In some embodiments, the first device 110-1 may support SBFD / TDD patterns (e.g., digital filters supported by the first device 110-1 and handover times supported by the UE).

[0123] In some example embodiments, the first device 110-1 may determine the second frame style based on the usage state of the first device 110-1. In some example embodiments, the first device 110-1 may determine the second frame style based on factors such as the temperature, power consumption, and remaining battery level of the first device 110-1.

[0124] According to the above process, the second device can obtain sufficient information that can be used to determine the appropriate frame pattern of the first device 110-1.

[0125] Furthermore, as described above, the first device 110 can report a second frame style (recommended frame style). In this case, the second device 120 can determine whether to apply the second frame style. In other words, the first frame style determined by the second device 120 can be the same as or different from the second frame style.

[0126] In some example embodiments, the first information can indicate the first frame style by indicating whether the second frame style is confirmed by the second device 120. That is, the second device 120 can confirm with the first device 110-1 whether the recommended TDD style is accepted by the second device 120. If it is confirmed, the recommended style can be used from subsequent frames. Otherwise, the first device 110-1 continues to use the default TDD style.

[0127] Optionally, refer to Figure 2 In some example embodiments, the first device 110-1 may receive configuration information 205 from the second device 120. The configuration information may indicate SBFD-related information. As an example embodiment, the configuration information may indicate at least one of the following: frequency band; Multiple time slots / symbols, wherein the frequency band is divided into multiple sub-bands, and at least one sub-band is used for DL ​​transmission and at least one sub-band is used for UL transmission, i.e. SBFD time slots / symbols, and the positions of the multiple time slots / symbols in the radio frame; The number of time slots / symbols, where the entire frequency band is used for DL ​​or UL transmission, i.e., non-SBFD time slots / symbols, and the location of the number of time slots / symbols in a radio frame; or Common TDD frame style configuration, such as DDDSU (style 1).

[0128] An example of configuration information indicating SBFD-related information is shown below.

[0129] TDD-UL-DL-ConfigCommon ::= SEQUENCE{ referenceSubcarrierSpacing SubcarrierSpacing, pattern1TDD-UL-DL-Pattern } TDD-UL-DL-Pattern ::= SEQUENCE{ dl-UL-TransmissionPeriodicityENUMERATED{ms2p5}, nrofDownlinkSlots INTEGER(3), nrofDownlinkSymbols INTEGER(10), nrofUplinkSlotsINTEGER (1), nrofUplinkSymbolsINTEGER(2).

[0130] It should be understood that configuration information may include other parameters depending on the specific scenario. This disclosure is not limited in this respect.

[0131] Furthermore, in some example embodiments, SBFD support can be implemented as a configurable / optional feature. The first device 110-1 can enable SBFD mode either by itself or by the second device 120.

[0132] In some example embodiments, reference is still made to Figure 2 The second device 120 can send 245 another first information to another first device 110-2. The other first information can indicate another first frame style from a set of pre-configured frame styles that are different from the first frame style configured for the first device 110-1. Then, the first device 110-2 performs 250 communication with the second device 120 on resources, at least in part based on the first frame style.

[0133] For better understanding, refer to Figures 3A-3CThis illustrates different frame styles 300A, 300B, and 300C in the same cell according to some embodiments of the present disclosure. Figures 3A-3C In the example, D can indicate a DL time slot, U can indicate a UL time slot, and S can indicate a special time slot. In one example, the first device 110-1 can select the frame style DDDSU, the first device 110-2 can select the frame style DUUUU, and a conventional device can use the frame style DDDSU. In this way, UE-specific frame style configuration is implemented.

[0134] According to the above process, the first device 110 can be configured with an appropriate frame style based on factors such as workload or environment, functional status, etc., through a set of pre-configured frame styles.

[0135] In this way, each first device can be configured with a (semi-static) TDD frame style, and the second device 120 can more easily manage resources (e.g., PDCCH / SRS / PUCCH / CSI-RS).

[0136] In addition, frame styles can be dynamically changed based on changes such as business type, via MAC CE or RRC.

[0137] Because the resources used for scheduling, HARQ, etc. can be reused, the first device 110 and the second device 120 do not need to consider UL and DL conflict handling issues, such as scheduling, measurement, or reporting, thereby reducing system complexity.

[0138] For better understanding, refer to Figure 4 and Figure 5 Two specific embodiments are described. Figure 4 An example flowchart 400 is shown, illustrating a first apparatus for determining a frame style according to an example of this disclosure.

[0139] At block 405, the first device 110-1 enables SBFD mode. At block 410, the first device 110-1 receives a common frame style configuration in the SIB. At block 415, the first device 110-1 receives a configuration of the frame style pool (i.e., a set of pre-configured frame styles). At block 420, the first device 110-1 selects a frame style based on, for example, service type.

[0140] If the DL transmission is overloaded, at box 425, the first device 110-1 selects a frame style, such as DDDDU, based on a frame style pool. If the UL transmission is overloaded, at box 430, the first device 110-1 selects another frame style, such as DDUUU or DUUUU, based on a frame style pool. Otherwise, at box 435, the first device 110-1 uses the common frame style.

[0141] At box 440, the first device 110-1 reports the selected frame style to the second device 120. At box 445, the first device 110-1 is waiting for the second device 120 to confirm, for example, whether the reported frame style is confirmed by the second device 120, such as MAC CE or RRC.

[0142] Figure 5 An example flowchart 500 of a second device determining a frame style according to an example of this disclosure is shown. At block 505, the second device 120 enables SBFD mode. At block 510, the second device 120 sends a common frame style configuration to the first device 110-1 in the SIB. At block 515, the second device 120 sends a configuration of the frame style pool. At block 520, the second device 120 determines the frame style based on reports from the first device 110-1 and / or the status of the second device 120 (e.g., DL buffer status, radio resources of the currently applied frame style).

[0143] Furthermore, if the communication state changes, at box 530, the second device 120 selects a new frame style from the pool of frame styles. At box 535, the second device 120 sends the new frame style indicated, for example, by MAC CE or RRC. Otherwise, if the state does not change, at box 525, the first device 110-1 uses the current frame style.

[0144] It should be understood that the example embodiments discussed above can be applied in static TDD, semi-static TDD, and dynamic TDD scenarios. This disclosure is not limited in this respect.

[0145] According to this disclosure, the complexity of frame pattern configuration in SBFD can be reduced, and almost all traditional mechanisms of TDD mode can be reused.

[0146] The method of this invention is efficient, compatible, and can significantly reduce the complexity of specifications. Furthermore, the first device can quickly respond to changes in interference, UL / DL service load, communication environment, functionality, service requirements, etc.
