Description
DEVICE, METHOD AND COMPUTER READABLE MEDIUM FOR COMMUNICATIONFIELD
[0001] Embodiments of the present disclosure generally relate to the field of communication, and in particular, to devices, methods and computer readable medium for a transmission configuration related to full duplex operation.BACKGROUND
[0002] With the development of communication technology, to enhance the performance of the communication system, several refined resource configuration manners had been introduced. For example, to easily utilize the multiple-input multiple-output (MIMO) technology, the Time Division Duplex (TDD) pattern had been studied and adopted, in which a time symbol may be configured as an uplink (UL) symbol, a downlink (DL) symbol or a flexible symbol. In this case, during a symbol, the configured whole bandwidth part (BWP) or carrier can be used for communication of corresponding link direction (for example, UL or DL) .
[0003] Furthermore, to enhance the frequency spectrum efficiency, a subband non-overlapping full duplex (SBFD) operation was proposed on the basis of TDD pattern. In the SBFD operation, a time unit (for example, a symbol, slot, sub-frame, frame, and so on) which may be also referred to as an SBFD time unit can be divided into a plurality of frequency subbands in the frequency domain. The plurality of frequency subbands may be respectively used for different link directions, for example, uplink (UL) frequency subband or downlink (DL) frequency subband. That is, for example, on a DL symbol configured with a UL subband, the network device may perform the DL transmission on the DL subband and perform the UL reception on the configured UL subband during this DL symbol. In this case, the BWP or carrier during a SBFD time unit (for example, this DL symbol) can be divided into multiple subbands that each is configured for one link direction. However, the frequency resources during an SBFD time unit are still not fully utilized. For example, the DL performance is reduced correspondingly.SUMMARY

[0044] As used herein, the singular forms ‘a’ , ‘an’ and ‘the’ are intended to include the plural forms as well, unless the context clearly indicates otherwise. The term ‘includes’ and its variants are to be read as open terms that mean ‘includes, but is not limited to. ’ The term ‘based on’ is to be read as ‘at least in part based on. ’ The term ‘one embodiment’ and ‘an embodiment’ are to be read as ‘at least one embodiment. ’ The term ‘another embodiment’ is to be read as ‘at least one other embodiment. ’ The terms ‘first, ’ ‘second, ’ and the like may refer to different or same objects. Other definitions, explicit and implicit, may be included below.
[0045] In some examples, values, procedures, or apparatus are referred to as ‘best, ’ ‘lowest, ’ ‘highest, ’ ‘minimum, ’ ‘maximum, ’ or the like. It will be appreciated that such descriptions are intended to indicate that a selection among many used functional alternatives can be made, and such selections need not be better, smaller, higher, or otherwise preferable to other selections.
[0046] The term “circuitry” used herein may refer to hardware circuits and / or combinations of hardware circuits and software. For example, the circuitry may be a combination of analog and / or digital hardware circuits with software / firmware. As a further example, the circuitry may be any portions of hardware processors with software including digital signal processor (s) , software, and memory (ies) that work together to cause an apparatus, such as a terminal device or a network device, to perform various functions. In a still further example, the circuitry may be hardware circuits and or processors, such as a microprocessor or a portion of a microprocessor, that requires software / firmware for operation, but the software may not be present when it is not needed for operation. As used herein, the term circuitry also covers an implementation of merely a hardware circuit or processor (s) or a portion of a hardware circuit or processor (s) and its (or their) accompanying software and / or firmware. In this disclosure, the subband and the frequency subband may be used interchangeable without any limitation. In this disclosure, the control channel may be interchangeably used with the physical downlink control channel (PDCCH) without any limitation.
[0047] In this disclosure, the term “full duplex frequency subband” refers to a range of frequency resources on which a network device can simultaneously perform the DL transmission and UL reception, for example, by utilizing the spatial division multiplex (SDM) or code division multiplex (CDM) technology. In turn, the terminal device performs one of the DL reception or UL transmission on the full duplex frequency subband. In this disclosure, the full duplex frequency subband may be also referred to be as “overlapped subband full duplex (OSFD) ” subband. For the simplicity purpose, the terms “the full duplex frequency subband” and “the full duplex subband” can be interchangeably used in this disclosure.
[0048] In addition, performing the simultaneous DL transmission and UL reception (e.g., from network device perspective) on the full duplex frequency subband may be also referred to as the “overlapped subband full duplex (OSFD) ” operation in this disclosure. In this disclosure, a time unit that configured with the full duplex frequency subband may be also referred to as a full duplex time unit or an “OSFD” time unit. In turn, the time unit that is not configured with the flexible frequency subband may be also referred non-OSFD time unit.
[0049] In some example embodiments of the disclosure, the non-OSFD time unit may include a normal time unit for a single link direction (e.g., UL time unit or DL time unit) and an SBFD time unit. As mentioned above, the SBFD time unit may be a DL configured with an UL frequency subband. In this case, the configured SBFD time unit may include multiple frequency subbands for different link directions. For example, during the SBFD time unit, a network device may perform DL transmission within the DL frequency subband and UL reception within UL frequency subband. However, in the SBFD operation, the network device cannot perform, within the same frequency subband, the simultaneous DL transmission and UL reception compared to the full duplex frequency subband. Some examples of the normal time unit, SBFD time unit and OSFD time unit are further discussed with reference to FIGS. 1B to 1C.
[0050] In some example embodiments of the disclosure, the time unit may be any metric of the time domain. For example, the time unit may be a frame, a subframe, a slot, or a symbol. Without any limitation, the time unit may be any other time duration. For example, the OSFD time unit may include, but not limited to, OSFD slot, OSFD symbol, OSFD frame and so on.
[0051] In some example embodiments of the disclosure, the expression “frequency resources within a subband of the OSFD time unit” only refers to the resources located within the subband with respect to the frequency domain; however, the time duration of these resources is unnecessary to be limited in the OSFD time unit if the time duration is not indicated. In some example embodiments of the disclosure, the term “Physical Resource Block (PRB) or resource block” used herein may refer to a resource base unit in the frequency domain.
[0052] In some example embodiments of the disclosure, the term “OSFD aware UE” used herein may refer to the terminal device which obtains the OSFD configuration for time units, for example, the subband division or location of the time units, and supports the OSFD operations with the network device.
[0053] In some example embodiments of the disclosure, the term “OSFD slot” refers to a slot including at least one OSFD symbol. In addition to the at least one OSFD symbol, the SBFD slot may further include one or more non-SBFD symbols.
[0054] As mentioned above, the SBFD operation can improve UL performance, including UL capacity, UL coverage and reduce UL transmission latency. However, DL performance is reduced correspondingly. As such, the OSFD operation that supports the simultaneous DL and UL transmission (at the network device) within the same frequency subband may be introduced. However, how to transmit or receive one or more transmissions on a plurality of time units which comprises the OSFD time unit is not designed. Only as an example, the resource assignment for the transmission crossing the OSFD time unit should be considered. Furthermore, at least the following content should be considered: the related spatial filter configuration, power control configuration, frequency hopping configuration, default configuration associated with the OSFD time unit, cross link interference (CLI) management configuration, and so on.
[0055] At least in view of the above, the example embodiments of the disclosure propose aspects for a transmission configuration related to full duplex operation.
[0056] In an aspect of the disclosure, a terminal device receives from a network device configuration information indicating a transmission associated with a plurality of time units that comprises a full duplex time unit (or OSFD time unit) . The full duplex time unit is configured with a full duplex frequency subband on which the network device can perform both a downlink transmission and an uplink reception. The transmission is indicated to be performed on at least one of the full duplex time unit or a non-full duplex time unit among the plurality of time units. For example, the transmission may be performed on one or more full duplex time units or one or more non-full duplex time units among the plurality of time units. Alternatively, the configuration information may indicate that the transmission is performed on both of the full duplex time unit (s) and the non-full duplex time unit (s) . Then, the terminal device performs the transmission based on the configuration information.
[0057] In this way, the terminal device and network device may communicate a transmission crossing the OSFD time with each other based on the configuration information.
[0058] For illustrative purposes, principle and example embodiments of the present disclosure will be described below with reference to FIGS. 1-16. However, it is to be noted that these embodiments are given to enable the skilled in the art to understand inventive concepts of the present disclosure and implement the solution as proposed herein, and not intended to limit scope of the present application in any way.
[0059] FIG. 1A illustrates an example environment 100 in which some embodiments of the present disclosure can be implemented.
[0060] The environment 100, which may be a part of a communication network, comprises a terminal device 110 and a network device 120. In some embodiments, the communication network may include NTN, NB-IoT and / or eMTC. In some other embodiments, the communication network may include any other possible communication network. Although not shown, it would be appreciated that one or more terminal devices, TRPs and network devices may be located in the environment 100. In some embodiments, the network device 120 supports the SBFD / OSFD operation. For example, during the SBFD time units, the network device 120 may transmit a downlink (DL) channel in DL subband to the terminal device 110 and receive an UL channel in UL subband from another terminal device (which is not shown in FIG. 1A) , simultaneously. In another example, during the full duplex time unit (or OSFD time unit) , the network device 120 may transmit a downlink (DL) channel to the terminal device 110 and receive an UL channel from another terminal device, simultaneously. Moreover, during the OSFD time unit, the DL channel and the UL channel may be within the same frequency range.
[0061] It is to be understood that the number of units and other objects in FIG. 1 are provided merely for the purpose of illustration without implying any limitations to the device environment 100. The environment 100 may include any suitable number of functionality units configured to implement example embodiments of the subject disclosure. Although not shown, it would be appreciated that one or more terminal devices may be located in the environment 100.
[0062] FIG. 1B illustrates example normal time units comprising downlink (DL) time units and uplink (UL) time units.
[0063] In FIG. 1B, an example TDD pattern including DL and UL time units is shown. The network device may transmit DL transmission to the terminal device on the DL time units. The network device may receive UL transmission from the terminal device on the UL time units. That is, in the normal time unit, the transmission is in one link direction.
[0064] FIG. 1C illustrates an example non-overlapping subband full duplex (SBFD) time unit.
[0065] As shown in FIG. 1C, the SBFD time unit is configured with multiple frequency subbands for different link directions. In the example of FIG. 1C, the network device may receive UL transmission within the UL subband 130 from a terminal device. Furthermore, the network device may transmit DL transmission within the DL subband to other terminal devices.
[0066] FIG. 1D illustrates an example full duplex time unit (or OSFD time unit) .
[0067] As shown in FIG. 1D, the OSFD time unit is configured with a full duplex frequency subband. The network device may transmit DL transmission to a terminal device and receive UL transmission from another terminal device within the full duplex frequency subband 140 simultaneously. Furthermore, the network device may transmit DL transmission using the DL subband.
[0068] At least to solve the related issues mentioned above, some embodiments of the disclosure are discussed with reference to FIGS. 2 to 16.
[0069] FIG. 2 illustrates a signaling process 200 for the transmission configuration related to the full duplex time unit according to some embodiments of the present disclosure. For the purpose of discussions, the process 200 will be described with reference to FIG. 1A. It would be appreciated that although the process 200 has been described with respect to communication environment of FIG. 1A, this process 200 may be likewise applied to other communication environments.
[0070] In the signaling process 200, the network device 120 transmits (210) configuration information 215 to the terminal device 110. The configuration information 215 indicates a transmission associated with a plurality of time units that comprises a full duplex time unit (which may be also referred to as “OSFD time unit” in some embodiments) . In some embodiments, the indicated transmission may comprise a plurality transmission repetitions crossing the plurality of time units. Alternatively, the indicated transmission may be one of a plurality of transmissions and the plurality of transmissions crosses the plurality of time units that has the OSFD time unit. Alternatively, the indicated transmission itself crosses the plurality of time units. The plurality of time units may be a plurality of slots which has an OSFD slot. In some other embodiments, the plurality of time units may be multiple symbols, frames, subframes, and so.
[0071] Still referring to FIG. 2, the terminal device 110 receives (220) the configuration information 215 from the network device 120 accordingly. Based on the configuration information 215, the terminal device 110 performs (230) the transmission with the network device 120. Correspondingly, the network device 120 also performs (240) the transmission with the terminal device 110 based on the configuration information 215.
[0072] In some embodiments, the configuration information 215 may be transmitted in a radio resource control (RRC) signaling. In addition or alternatively, the configuration information 215 may be transmitted in downlink control information (DCI) . In addition or alternatively, the configuration 215 may be transmitted in medium access control (MAC) control element (CE) .
[0073] In some embodiments, the configuration information 215 may include a first configuration. The first configuration indicates that the transmission is to be performed on the full duplex time unit or the non-full duplex time unit. For example, the transmission (e.g., DL transmission or UL transmission) may be restricted only on the OSFD time unit (s) or non-OSFD time units among the plurality of time units.
[0074] To discuss clarity, the first configuration is further discussed with reference to FIGS. 3A to 3D.
[0075] FIG. 3A to FIG. 3D illustrate some example channel transmissions based on the configuration information comprising a first configuration according to some embodiments of the present disclosure;
[0076] In the example of FIG. 3A, the channel transmission (which is shown as PXSCH) is indicated by the configuration information including the first configuration to be performed only on the OSFD time unit. As such, the transmission is performed on the OSFD symbols, rather than the non-symbols (which are shown as DL symbols in FIG. 3A) . In some embodiments of the disclosure, the PXSCH may refer to the physical shared channel which includes a physical uplink shared channel (PUSCH) and a physical downlink shared channel (PDSCH) .
[0077] Alternatively, in the example of FIG. 3B, the channel transmission (which is shown as PXSCH) is indicated by the configuration information including the first configuration to be performed only on the non-OSFD time unit. As such, the transmission is performed on the non-OSFD symbols (which are shown as the DL symbols in FIG. 3B) , rather than the OSFD symbols.
[0078] In the example of FIG. 3C, the channel transmission (which is shown as PUSCH) is indicated by the configuration information including the first configuration to be performed only on the OSFD time unit. As such, the transmission is performed on the OSFD symbols, rather than the non-OSFD symbols (which are shown as UL symbols and DL symbols in FIG. 3C) .
[0079] In the example of FIG. 3D, the channel transmission (which is shown as PUSCH) is indicated by the configuration information including the first configuration to be performed only on the non-OSFD time unit. As such, the transmission is performed on the non-OSFD time unit, such as on the UL subband of the SBFD time unit and the UL time unit, rather than the OSFD time units.
[0080] Referring back to FIG. 2, in some embodiments, in the case that the first configuration indicates that the transmission is to be performed on the full duplex time unit or the non-full duplex time unit, the terminal device 110 may need to determine one of the full duplex time unit or the non-full duplex time unit as valid for the transmission. Then, the terminal device 110 may perform the transmission on the valid one of the full duplex time unit (s) or non-full duplex time unit (s) among the plurality of time units.
[0081] In some embodiments, the network device 120 may transmit a configuration or an indication that indicates the full duplex time unit or the non-full duplex time unit (normal time unit and / or SBFD time unit) as valid. For example, for semi-statically configured transmissions / receptions (i.e., without activation DCI) , the valid symbol type (i.e., OSFD time unit type or non-SBFD time unit type) may be explicitly configured by radio resource control (RRC) signaling. In another example, the valid symbol type (such as OSFD symbol, SBFD symbol, or UL only symbol) for semi-persistent (SP) -channel state information (CSI) on physical uplink control channel (PUCCH) or physical uplink shared channel (PUSCH) may be explicitly configured in CSI-ReportConfig. In another example, the valid symbol type for type 2 configured grant (CG) PUSCH may be explicitly configured in ConfiguredGrantConfig. In a further example, the valid symbol type (such as OSFD symbol or DL only symbol) for semi-persistent-scheduling (SPS) physical downlink shared channel (PDSCH) may be explicitly configured in SPS-Config. In a yet example, the valid symbol type for semi-persistent sounding resource signal (SRS) may be explicitly configured in SRS-Config / SRS-ResourceSet / SRS-Resource.
[0082] Once determining which time unit is valid (OSFD time unit, normal time unit or SBFD time unit) , other invalid symbols (type) may be considered as invalid resource and the transmissions / receptions are dropped or deferred. For example, the configured symbol type for SPS SRS, the SRS-Config may indicate as non-OSFD symbols, then the SPS or SRS can be only transmitted on SBFD symbols and UL only symbols, and the SPS SRS on OSFD symbols may be dropped or deferred.
[0083] Alternatively or in addition to the explicit indication of the valid time unit type, in some embodiments, the valid time unit type may be determined by determining the time unit on which the first transmission or initial transmission is transmitted.
[0084] In some embodiments, a transmission is one of plurality of transmissions. The terminal device 110 and network device 120 may determine a first time unit for transmitting an initial or first transmission of the plurality of transmissions after an activation. The terminal device 110 and network device 120 may further determine whether the first time unit belongs to the full duplex time unit or the non-full duplex time unit. If the first time unit belongs to the full duplex time unit, the terminal device 110 may determine the full duplex time unit as valid for the transmission. If the first time unit belongs to the non-full duplex time unit, the terminal device 110 may determine the non-full duplex time unit as valid for the transmission.
[0085] To discuss clarity, some embodiments related to the determination of a type of the first time unit is further discussed with reference to FIG. 4A.
[0086] FIG. 4A illustrates an example of a determination of the valid time unit type according to some embodiments of the disclosure.
[0087] As shown in FIG. 4A, the DCI activates a transport block processing over multiple slots (TBMoS) which crosses a plurality of time units, and the plurality of time units includes OSFD time unit. For the dynamical scheduled transmissions / receptions, the valid time unit type of the plurality of time units may be determined based on the time unit type on which the first (or initial) is transmitted or received. Specifically, the time unit for transmitting or receiving the first transmission of the TBMoS may be determined by the DCI. In an example, if the time unit type of the first transmission or reception is determined as the OSFD time unit (for example, the first transmission / reception may be determined by the scheduling offset “K0, K1 or K2” and time domain resource assignment (TDRA) , the valid time unit type for subsequent transmission / reception may be the OSFD time unit.
[0088] Otherwise, if the first transmission or reception is in a non-OSFD time unit, then the subsequent transmission or reception symbol type may be on non-OSFD symbols. In other words, other time unit type may be considered invalid, and skipped or postponed for transmission or reception.
[0089] In the example of FIG. 4A, for TBoMS transmission over multiple slots, the time unit type for the first transmission is an SBFD time unit (i.e., a non-OSFD time unit) . In this case, the subsequent transmission or reception may be on non-OSFD symbols. In turn, once encountering an OSFD symbol, it may be considered invalid and the terminal device 110 may postpone transmissions to the SBFD time unit or UL only time unit.
[0090] FIG. 4B illustrates another example of a determination of the valid time unit type according to some embodiments of the disclosure.
[0091] As shown in FIG. 4B, DCI may activate semi persistent scheduling (SPS) transmissions. Similarly, in some embodiments, the valid time unit type may be determined based on the symbol type for the first (initial) transmissions / receptions associated with this DCI.
[0092] In an example, the valid time unit type (OSFD time unit or non-OSFD time unit) for SP-CSI on PUCCH or PUSCH may be determined based on the time unit type for the first PUSCH / PUCCH after activation. Specifically, if the first transmission / reception occasion occurs in OSFD symbols, the subsequent transmission may be performed only on OSFD symbols. As shown in FIG. 4B, the PUSCH 410 on the UL subband should be dropped or deferred to the full duplex frequency subband.
[0093] In another example, the valid time unit type for type 2 configured grant (CG) PUSCH may be determined based on the time unit type for the first CG PUSCH associated with activation DCI. In a further example, the valid time unit type for SPS PDSCH may be determined based on the time unit type for the first SPS PDSCH associated with activation DCI. In a yet example, the valid time unit type for semi-persistent SRS may be determined based on the time unit type for the first SRS transmission after the activation.
[0094] In the example of FIG. 4B, after the activation DCI, the first PUSCH for type 2 CG PUSCH is transmitted on an OSFD symbol (e.g., in slot n+2) . In this case, the subsequent CG PUSCH transmission on another slot (e.g., in slot n+8) configured with SBFD symbol (s) should be dropped or deferred, since the other slot is of non-OSFD slot type.
[0095] Referring back to FIG. 2, alternatively, in some embodiments, the configuration information 215 may include a second configuration. The second configuration indicates that the transmission may be performed on the full duplex time unit and the non-full duplex time unit. For discussion purposes, the transmission indicated by the second configuration is further discussed with reference to FIGS. 5A to 5C.
[0096] FIG. 5A to FIG. 5C illustrate example channel transmissions based on the configuration information comprising a second configuration according to some embodiments of the present disclosure.
[0097] In the example of FIG. 5A, the second configuration may indicate that the transmissions (including transmitting the transmission and receiving the transmission) may be performed on the OSFD time unit (s) and non-OSFD time unit (s) (which include the SBFD time unit and normal time unit) .
[0098] Furthermore, as mentioned above, the non-OSFD time unit includes the SBFD time unit and the normal time unit (e.g., UL time unit or DL time unit) for a single link direction. Alternatively, in some embodiments, the second configuration may indicate that the transmissions may be transmitted on the OSFD time unit and one of the SBFD time unit or normal time unit. In the example of FIG. 5B, the transmission may be indicated to be performed on OSFD time units and SBFD time units. Accordingly, the PUSCH transmissions in FIG. 5B are performed within the full duplex frequency subband of the OSFD time unit (s) and within the UL subband of the SBFD time unit (s) .
[0099] Alternatively, in the example of FIG. 5C, the transmission may be indicated to be performed on OSFD time units and normal time unit (s) . Accordingly, the PUSCH transmissions in FIG. 5C are performed within the full duplex frequency subband of the OSFD time unit (s) and on the UL time unit (s) . In the examples, the UL transmission may be performed on OSFD time unit (s) and SBFD time unit (s) , or the UL transmission may be performed on OSFD time unit (s) and UL time unit (s) . In addition, the DL transmission may be performed on OSFD time unit (d) and DL time unit (s) .
[0100] Referring back to FIG. 2, alternatively, in some embodiments, the configuration information 215 may includes a third configuration. The third configuration indicates that the transmission is to be performed within the full duplex frequency subband or a further frequency subband, wherein the further subband is configured for the downlink direction or the uplink direction. In this embodiment, the transmission is configured on one of the full duplex frequency subband or further frequency subband in the frequency domain. For discussion purposes, the third configuration is further discussed with reference to FIG. 6A to 6B.
[0101] FIG. 6A to FIG. 6B illustrate example channel transmissions based on the configuration information comprising a third configuration according to some embodiments of the present disclosure.
[0102] In the example of FIG. 6A, the transmission may be indicated to be performed only within the full duplex frequency subband. In this case, the example PUSCH transmission is performed within the full duplex frequency subband of the OSFD time unit accordingly.
[0103] In the example of FIG. 6B, the transmission may be indicated to be performed on within a further frequency subband other than the full duplex frequency subband. In this case, the example PDSCH transmissions are transmitted on the DL subband of the OSFD time unit (s) . In addition, in some other embodiments, the transmission (s) may be transmitted on UL frequency subband of the SBFD time unit or DL frequency subband of the SBFD time unit without any limitation. For example, the transmission may be restricted within the full duplex frequency subband of the OSFD time unit or an UL frequency subband of the UL time unit.
[0104] Similarly, in the case that the configuration information 215 indicates that the transmission is to be performed within the full duplex frequency subband or a further frequency subband, the terminal device 110 (or the network device 120) may need to determine the valid one of the full duplex frequency subband or further frequency subband.
[0105] For example, the terminal device 110 may determine one of the full duplex frequency subband or a further frequency subband as valid for the transmission, wherein the further subband is configured for an uplink direction or a downlink direction. Then, the terminal device 110 may perform the transmission within the valid one of the full duplex frequency subband or the further subband.
[0106] In some embodiments, the valid one of the full duplex frequency subband or the further subband may be determined based on the allocated physical resource block (PRB) ratio in at least one of the full duplex frequency subband or the further subband.
[0107] As an example, the terminal device 110 may determine a first portion of resources allocated to the transmission which is within the full duplex frequency subband, and determine a second portion of the resources which is within the further frequency subband. The terminal device 110 may further determine one of the full duplex frequency subband or further frequency as valid based on at least one of the first portion or the second portion.
[0108] For example, if the first portion is above 50%of the frequency resource width allocated to the transmission, the terminal device 110 may determine the full duplex frequency subband is the valid one, and vice versa. Alternatively, if the first portion is above the second portion, the terminal device 110 may determine that the full duplex frequency subband is the valid one, and vice versa. Alternatively, if the second portion is smaller than 50%of the frequency resource width, the terminal device 110 may determine that the full duplex frequency subband is the valid one, and vice versa. That is, in some cases, the terminal device 110 may determine the valid frequency subband by determining one of the first portion or the second portion. To discuss clarity, the above embodiments are further discussed with reference to FIG. 7A.
[0109] FIG. 7A illustrates an example of a determination of the valid frequency subband type according to some embodiments of the disclosure.
[0110] In the example of FIG. 7A, the PRB ratio in OSFD subband is larger than the PRB ratio in non-OSFD subband. In this case, if the configuration information 215 indicates that the transmission is restricted to full duplex frequency subband or further frequency subband, then the transmission may be performed on OSFD subband only. Otherwise, if the PRB ratio in OSFD subband is smaller than or equal to the PRB ratio in non-OSFD subband, the transmission may be performed only on non-OSFD subband (i.e., the UL subband as shown in FIG. 7A) . Moreover, the terminal device 110 (or network device 120) may need to perform a puncturing or rate matching operation associated with the first portion or the second portion which is determined as invalid.
[0111] As an example, a demodulation reference signal (DMRS) is indicated to be performed within only one subband type (i.e., the full duplex frequency subband or the further frequency subband) . In this case, the DMRS sequence mapped to the RBs outside the valid subband type should be punctured. In this example, the terminal device 110 (or network device 120) may need to perform a puncturing or rate matching operation associated with the second portion 710.
[0112] In addition, in some embodiments, the number of PRBs for transport block size (TBS) determination is based on the assigned PRBs within valid subband type. In the example of FIG. 7A, the PRB ratio in the full duplex frequency subband is larger than the PRB ratio in non-OSFD subband, and the transmission are restricted to full duplex frequency subband only. Accordingly, the RB allocated to the transmission in non-OSFD subband may be determined as invalid, and the terminal device 110 may perform rate matching or puncturing for PUSCH transmission.
[0113] Referring back to FIG. 2, alternatively or in addition to the determination of a valid frequency subband based on the resource ratio, the network device 120 may explicitly indicate the valid frequency subband. In some embodiments, the network device 120 may transmit, to the terminal device, a configuration or an indication that indicates the full duplex frequency subband or the further frequency as valid.
[0114] In an example, this indication or configuration may be transmitted in RRC signaling. In this case, the terminal device 110 may determine the valid subband type based on RRC configuration. Some specific examples are discussed in following.
[0115] The valid frequency subband type (such as full duplex frequency subband, UL frequency subband of SBFD time unit, or UL only subband) for SP-CSI report on PUCCH or PUSCH may be explicitly configured in CSI-ReportConfig. The valid frequency subband type for type 2 CG PUSCH may be explicitly configured in ConfiguredGrantConfig. The valid frequency subband type for SPS PDSCH (such as, full duplex frequency subband or DL only subband) may be explicitly configured in SPS-Config. The valid frequency subband type for semi-persistent SRS (such as full duplex frequency subband, UL frequency subband of SBFD time unit, or UL only subband) may be explicitly configured in SRS-Config, SRS-ResourceSet, or SRS-Resource.
[0116] In some embodiments, the configured frequency resources may cross multiple subband types in some time units. In this case, the terminal device 110 may perform the transmissions / receptions only on the valid frequency subband type based on the RRC configuration. In turn, resources within other subband type may be considered as invalid resources.
[0117] In addition or alternatively, in some embodiments, if the configured transmission is completely within a frequency subband, then the transmission may be performed. Furthermore, if the configured transmission crosses a boundary between different frequency subbands, the configured transmission may be determined as invalid. The invalid transmission may be dropped or deferred.
[0118] For discussion clarity, some example transmissions associated with one or more frequency subbands are further discussed with reference to FIGS. 8A and 8B.
[0119] FIG. 8A to FIG. 8B illustrate example channel transmissions associated with one or more frequency subbands according to some embodiments of the present disclosure.
[0120] In the example of FIG. 8A, a plurality of PDSCH repetitions or SPS PDSCH (repetitions) cross OSFD symbols and non-OSFD symbols. Furthermore, one or more repetitions of the plurality of the repetitions may cross the frequency subbands. In this case, the repetition across the frequency subbands may be determined as invalid, and may be dropped or deferred. As shown in FIG. 8A, the PDSCH 2 810 across the full duplex frequency subband and DL frequency subband is dropped or deferred.
[0121] In the example of FIG. 8B, multiple PDSCHs scheduled by a single DCI cross OSFD symbols and non-OSFD symbols. Moreover, each of the multiple PDSCHs is located within full duplex frequency subband or a further frequency subband. In this case, the multiple PDSCHs are valid completely.
[0122] Referring back to FIG. 2, in addition or alternatively, in some embodiments, the configuration information 215 may include a fourth configuration. The fourth configuration may indicate that the transmission is to be performed within the full duplex frequency subband and a further frequency subband. For example, the DL transmission may be performed within the full duplex frequency subband and DL frequency subband (e.g., DL only frequency subband of DL time unit or DL frequency subband of SBFD time unit) . In another example, the UL transmission may be within UL frequency subband of the SBFD time unit and the full duplex frequency subband. For discussion clarity, the transmission indicated by the fourth configuration is further discussed with reference to FIGS 9A to 9B.
[0123] FIG. 9A to FIG. 9B illustrate example channel transmissions based on the configuration information comprising a fourth configuration according to some embodiments of the present disclosure.
[0124] In the example of FIG. 9A, a plurality of PDSCH transmissions is indicated to be performed within the full duplex frequency subband and the further frequency subband. Accordingly, the plurality of PDSCH transmissions may be performed across different frequency subbands.
[0125] In the example of FIG. 9B, the same time unit may be configured as both the OSFD time unit and SBFD time unit. In this case, if a plurality of PDSCH transmissions is indicated to be performed within the full duplex frequency subband and the further frequency subband, then the plurality of PDSCH transmissions may be performed across the boundary between the full duplex frequency subband and the neighboring UL frequency subband.
[0126] Referring back to FIG. 2, in addition, in some embodiments, if the transmission is indicated to be performed within the full duplex frequency subband and the further frequency subband (UL or DL frequency subband) , it may need to determine whether some certain conditions are fulfilled before performing the transmission.
[0127] In some embodiments, the terminal device 110 (or network device 120) may determine whether at least one of the following conditions is fulfilled: the time domain resources for the transmission in the full duplex frequency subband is the same as time domain resources for the transmission in the further frequency subband; or a first spatial filter for the full duplex frequency subband is the same as a second spatial filter for the further frequency subband. In addition or alternatively, the terminal device 110 (or network device 120) may determine whether at least one of the following conditions is fulfilled: there is no guardband between the full duplex frequency subband and the further frequency subband, or a first modulation and coding scheme (MCS) for the full duplex frequency subband is the same as a second MCS for the further frequency subband. To discuss clarity, the transmission across frequency subbands is further discussed with reference to FIG. 10A.
[0128] FIG. 10A illustrates example channel transmission across the full duplex frequency subband and downlink (DL) frequency subband according to some embodiments of the present disclosure.
[0129] In the example of FIG. 10A, the PDSCH may be transmitted across the full duplex frequency subband and the DL frequency subband only in the case that the following conditions are met. A first condition may be that the same time domain resources are used for both the OSFD subband segment and non-OSFD segment of the PDSCH. A second condition may be that the same spatial domain filter is used for both the OSFD segment and non-OSFD segment of the PDSCH. A third condition may be that there is no guardband configured between OSFD subband and DL only subband of the OSFD time unit. The fourth condition may be that the same MCS are indicated for both the OSFD subband segment and non-OSFD segment of the PDSCH. Furthermore, in the example of FIG. 10A, scheduled or SPS PDSCH may be transmitted across OSFD subband and DL only subband in OSFD symbols. In addition, the DMRS may be also mapped to OSFD subband and DL only subband. Otherwise, in some embodiments, if the above conditions are not fulfilled, the terminal device or network device may drop or defer the transmission.
[0130] Alternatively, in some embodiments, the further frequency subband may be the UL subband of the SBFD time unit, e.g., the OSFD time unit is also configured as the SBFD time unit. That is, the transmission may be performed across the full duplex frequency subband and the UL frequency subband. Only for discussion purposes, the transmission across the full duplex frequency subband and the UL frequency subband is further discussed with reference to FIG. 10B.
[0131] FIG. 10B illustrates example channel transmission across the full duplex frequency subband and an uplink (UL) frequency subband according to some embodiments of the present disclosure.
[0132] In the example of FIG. 10B, the PUSCH may be transmitted across the full duplex frequency subband and the UL frequency subband only in the case that the following conditions are met. A first condition may be that the same time domain resources are used for both the OSFD subband segment and SBFD segment of the PUSCH. A second condition may be that the same spatial domain filter (one SRS resource indicator, SRI) and power control parameters are used for both the OSFD segment and SBFD segment of the PUSCH. The third condition may be that there is no guardband configured between OSFD subband and SBFD subband in OSFD symbols. The fourth condition may be that the same MCS are indicated for both the OSFD subband segment and SBFD segment of the PUSCH. As an example, CG PUSCH and DMRS may be transmitted across OSFD subband and SBFD subband in this OSFD symbols.
[0133] Referring back to FIG. 2, as mentioned above, the information configuration 215 including the second configuration may indicate the transmission to be performed on the OSFD time unit (s) and non-OSFD time unit (s) . In some embodiments, similarly, the transmission may be performed only in the case that some conditions related to the OSFD time unit and non-SBFD time unit are fulfilled.
[0134] In some embodiments, the above conditions for the transmission across the OSFD time unit and non-OSFD time unit may include at least one of the following: a phase continuity is maintained between the full duplex time unit and a non-full duplex time unit, or a power control parameter is the same between the full duplex time unit and the non-full duplex time unit. In addition or alternatively, the conditions may include at least one of the following: a spatial filter parameter is the same between the full duplex time unit and the non-full duplex time unit; or a timing parameter is the same between the full duplex time unit and the non-full duplex time unit. For discussion clarity, the conditions for the transmission across the OSFD time unit and non-OSFD time unit are further discussed with reference to FIG. 11.
[0135] FIG. 11 illustrates example transmission crossing the full duplex time unit (OSFD time unit) and non-full duplex time unit according to some embodiments of the present disclosure.
[0136] In the example of FIG. 11, for a physical channel / signal occasion mapped to OSFD and non-OSFD symbols (including SBFD symbol and DL / UL only symbol) within a slot, the transmission may be performed in the case that the following conditions are met. The first condition may be whether the phase continuity can be maintained across OSFD and non-OSFD symbols. The second condition may be whether there are same or different transmission / reception parameters e.g. power control, spatial / QCL assumption, UL timing etc. applied in OSFD and non-OSFD symbols. The third condition may be whether there is a guard period between the OSFD and non-OSFD symbols, and so on. As an example, in the case that there is no guard period between the OSFD and SBFD symbols, and the same power control parameter (s) , spatial / QCL assumption parameters and UL timing are applied to OSFD symbols and SBFD symbols, the terminal device 110 may transmit a PUSCH across OSFD symbols and SBFD symbols. In this case, the terminal device may transmit or receive the physical channel / signal within the slot including OSFD time unit, SBFD time unit and normal time unit if the above conditions are fulfilled.
[0137] Referring back to FIG. 2, alternatively, in some embodiments, the terminal device 110 may not transmit or receive the physical channel / signal crossing the boundary between the OSFD time unit and non-OSFD time unit. In some embodiments, the terminal device 110 may transmitting a first transmission of the plurality of transmissions which is on the full duplex time unit or non-full duplex time unit. Furthermore, the terminal device 110 may drop or defer a second transmission of the plurality of transmissions which overlaps with the full duplex time unit and non-full duplex time unit.
[0138] In addition, in some embodiments, the transmit power control (TPC) parameters may be separately applied to transmission on the full duplex time unit or transmission on the non-full duplex time unit. For example, separate TPC parameters for PUSCH / PUCCH / SRS transmissions (including repetition and non-repetition transmission) on UL only symbols, SBFD symbols and OSFD symbols in different slots may be supported.
[0139] In an example, the transmission is a first transmission on the full duplex time unit, and the terminal device 110 may further perform a second transmission on an SBFD time unit and a third transmission on the UL only time unit. In this case, a first transmit power control parameter may be configured for the first transmission, a second transmit power control parameter may be configured for the second transmission, and a third transmit power control parameter may be configured for the third transmission.
[0140] In addition or alternatively, in some embodiments, the spatial filters may be also separately applied to transmission on the full duplex time unit or transmission on the non-full duplex time unit. For example, separate spatial domain configuration or indication may be for PUSCH / PUCCH / SRS transmissions on UL only symbols, SBFD symbols and OSFD symbols in different slots including repetition and non-repetition.
[0141] In an example, a first spatial filter configuration may be configured for the above first transmission, a second spatial filter configuration may be configured for the above second transmission, and a third spatial filter configuration may be configured for the above third transmission.
[0142] In another example, three SRIs in DCI or srs-ResourceIndicators may be included in ConfiguredGrantConfig, and each of the SRIs may be used for respective PUSCH transmission on UL only symbols, SBFD symbols and OSFD symbols in different slots for PUSCH repetition or non-repetition transmission.
[0143] Referring back to FIG. 2, in some situations, the terminal device 110 may communicate with multiple transmit-receive points (TRP) . In this case, in the OSFD time unit (s) , transmission repetitions of a plurality of transmission repetitions may be performed in different frequency subband. As an example, the terminal device 110 may receive, within the full duplex frequency subband and from a first transmit and receive point (TRP) , a first transmission repetition of the plurality of transmission repetitions. In addition, the terminal device 110 may receive, within a downlink frequency subband and from a second TRP, a second transmission repetition of the plurality of transmission repetitions.
[0144] That is, in an example, in multi-TRP case, a plurality of PDSCH repetitions may cross OSFD subband and DL only subband in OSFD symbols and each repetition should be within OSFD subband or within DL only subband. In another example, multi-PDSCHs scheduled by a single DCI may cross OSFD subband and DL only subband, and each PDSCH should be within OSFD subband or within DL only subband.
[0145] In some embodiments, the resource assignment information for the transmission repetition may be separately applied to the different frequency subbands for the plurality of transmission repetitions. In an example, the full duplex frequency subband may be configured with a first frequency domain resource allocation (FDRA) configuration for the first transmission repetition. The DL frequency subband may be configured with a second FDRA configuration for the second transmission repetition. Thus, the starting PRB in the first FDRA is the starting PRB for the transmission within the full duplex frequency subband.
[0146] Alternatively, in some embodiments, there may be a common FDRA configuration for the full duplex frequency subband and the other frequency subband for the plurality of transmission repetitions. Furthermore, the full duplex frequency subband or the DL frequency subband is further applied with one or more RB offset parameters. To discuss clarity, this embodiment is further discussed with reference to FIG. 12A.
[0147] FIG. 12A illustrates example common frequency domain resource assignment (FDRA) configuration and RB offsets for a plurality of transmission repetitions under the multi-transmit and receive points (TRP) according to some embodiments of the present disclosure;
[0148] In the example of FIG. 12A, a single FDRA configuration / indication may be used for one subband type (OSFD or DL only subband) . Moreover, the FDRA configuration / indication together with RB offset (s) 1210 may be used to determine frequency resources for the transmission repetition on the other subband type. In an example, the RB offsets may be the number of RBs between a starting RB of the lowest PDSCH and the starting RB of higher frequency position PDSCH. In an example, the single FDRA and an RB offset which are separately used for PDSCH within OSFD subband and within DL only subband may be included in the DCI.
[0149] In addition, in some embodiments, the time resources for the first transmission repetition in the full duplex frequency subband and the second transmission in the other DL frequency subband may be determined similarly.
[0150] In some embodiments, the full duplex frequency subband may be associated with a first time domain resource allocation (TDRA) configuration, and the DL frequency subband may be associated with a second TDRA configuration. That is, separate (or two) TDRA configurations, indications or interpretations may be applied to the full duplex frequency subband and DL only subband.
[0151] Alternatively, in some embodiments, the full duplex frequency subband and DL only subband may be associated with the same common TDRA configuration. In an example, a single TDRA configuration / indication may be applied for one frequency subband type (full duplex frequency subband or DL only subband) . Furthermore, additional symbol offset (s) may be used to determine PDSCH resource for the other subband type. To discuss clarity, the TDRA configuration for the PDSCHs in different frequency subbands is further discussed with reference to FIG. 12B.
[0152] FIG. 12B illustrates example common time domain resource assignment (TDRA) configuration and symbols offsets for a plurality of transmission repetitions under the multi-transmit and receive points (TRP) according to some embodiments of the present disclosure.
[0153] In the example of FIG. 12B, the single common TDRA and symbol offset (s) which are separately used for PDSCH transmissions within OSFD subband and within DL only subband may be included in the DCI. The symbol offset (s) may be the delay between the starting time of the PDSCH 1 and the starting time of the PDSCH 2.
[0154] Referring back to FIG. 2, in addition or alternatively, in some situations, the configured grant (CG) transmission repetitions may cross OSFD symbols and SBFD symbols in different slots. In this case, the TDRA and / or FDRA for these transmission repetitions should be considered. Specifically, assuming that transmission includes a plurality of transmission repetitions that is configured grant, and the terminal device 110 (or the network device 120) performs the transmission by transmitting the plurality of transmission repetitions on the full duplex time unit and SBFD time unit.
[0155] In some embodiments, the full duplex time unit may be associated with at least one of a third time domain resource allocation (TDRA) configuration or a third FDRA configuration, and the SBFD time unit may be associated with at least one of a fourth TDRA configuration or a fourth FDRA configuration. That is, separate TDRA or FDRA resource configurations or indications may be applied SBFD symbols and OSFD symbols.
[0156] Alternatively, in some embodiments, the full duplex time unit and the SBFD time unit are associated with a common resource configuration, and one of the full duplex time unit and the SBFD time unit is associated with one or more offset parameters. In an example, a single resource configuration or indication may be applied to one symbol type (SBFD or OSFD symbol) , and the single resource configuration together with RB / symbols offset (s) configuration, indication or determination may be used determine resource for the other symbol type.
[0157] In addition or alternatively, in some embodiments, the resources for uplink channel which is not located within the full duplex frequency subband of the OSFD time unit or the UL subband of the OSFD time unit may be determined as invalid. In some embodiments, the terminal device 110 may receive, from the network device 120, an indication that resources for the transmission which is not located within the full duplex frequency subband in the frequency domain is invalid. To discuss clarity, this embodiment is further discussed with reference to FIG. 13.
[0158] FIG. 13 illustrates example transmission which is not completely configured within the full duplex frequency subband according to some embodiments of the present disclosure.
[0159] As shown in FIG. 13, the resources 1310 configured for the PUSCH which is not located in the full duplex frequency subband may be considered as invalid. In an example, there may be a single resource configuration / indication, and the resource blocks (RB) outside UL usable PRBs in OSFD symbols are invalid.
[0160] Referring back to FIG. 2, in addition or alternatively, the frequency hopping configuration may be similarly determined for the OSFD time units and non-OSFD time units.
[0161] In some embodiments, if PUSCH / PUCCH / SRS transmissions cross SBFD symbols and OSFD symbols, separate FH (Frequency Hopping) offsets maybe configured or indicated for PUSCH transmissions on SBFD symbols and OSFD symbols respectively. The separate FH offsets may be obtained in the following manners.
[0162] In some embodiments, the full duplex time unit may be associated with a first frequency hopping (FH) offset parameter and the SBFD time unit is associated with a second FH offset parameter.
[0163] As an example, two sets of FH offsets may be included in DCI or RRC configuration and the two sets of FH offsets may be used for PUSCH / PUCCH / SRS on SBFD time units and OSFD time units separately. Moreover, in some embodiments, the FH offsets values may be determined based on the OSFD subband and SBFD subband size separately. That is, the first sets of FH offset may be determined based on a first size of the full duplex frequency subband and the second sets of FH offset may be determined based on a second size of a further frequency subband.
[0164] Alternatively, in some embodiments, the full duplex time unit and the SBFD time unit are associated with a common FH offset parameter, and one of the full duplex time unit and the SBFD time unit is associated with a further frequency offset. In an example, one set of FH offsets and an offset Δ may be included in DCI or RRC configuration. The one set of FH offsets may be used for the one of the OSFD time unit or non-OSFD time unit. Moreover, the one set of FH offsets and the offset Δ may be used for the other one of the OSFD time unit or non-OSFD time unit. For example, a second FH offset for the other time unit may be obtain by the one set of FH offsets plus Δ.
[0165] In addition, in some embodiments, the terminal device 110 expects that the number of FH offsets for PUSCH transmission in SBFD symbol is the same as the number of FH offset for PUSCH transmission in OSFD symbol. In some embodiments, the FH offsets or offset Δ for PUSCH transmissions in OSFD symbols are not configured, FH for PUSCH transmissions in OSFD symbols may be disabled.
[0166] Still referring to FIG. 2, in addition, in some embodiments, the configuration information 215 may specific to the terminal device. For example, the configuration information may be per-UE and is applied to all the channel / signal. The configuration information 215 may be based on UE capabilities.
[0167] In addition or alternatively, the configuration information 215 may specific to signal or channel to be transmitted. As an example, the configuration information 215 may be per channel / signal. For example, the SSB may use the configuration information comprising the second configuration as default configuration. In some embodiments, the CSI-RS, PDSCH may configured with configuration information 215 comprising the second configuration and / or third configuration through RRC. UL PRACH may be transmitted only based on the configuration information 215 comprising the first configuration. In an example, the UL PRACH may be only transmitted on UL only symbols. In some embodiments, PUSCH, SRS, PUCCH may be configured with configuration information comprising the first configuration or the second configuration 2.
[0168] In some embodiments, considering intra-subband CLI, only UE-specific DL / UL can be transmitted on the OSFD subband, and UE does not expect common information, such as SSB and PDCCH in CSS are configured in the OSFD subband. The common information can be only transmitted on DL only subband.
[0169] In some embodiments, the configuration information 215 comprising the first configuration may be default configuration information. The terminal device 110 may perform a random access procedure based on the default configuration information. In addition or alternatively, the terminal device 110 may perform a transport block processing over multiple slots (TBoMS) based on the default configuration information. In addition or alternatively, the terminal device 110 may perform a plurality of transmission repetitions based on the default configuration information. In addition or alternatively, the terminal device 110 may perform an operation associated with a demodulation reference signal (DMRS) bundling based on the default configuration information.
[0170] In some other embodiments, the defaulted configuration may be the first configuration and the configuration that the receptions are restricted to DL subband only or OSFD subband only. In this case, if other configuration is configured, the default configuration may be disabled. In some other embodiments, the terminal device 110 may operate based on the first configuration during initial access and after in RRC connected state based on the RRC configuration. In some other embodiments, if TBoMS or repetitions or DMRS time bundling is used, then the first configuration and the configuration that the receptions are restricted to DL subband only or OSFD subband only are adopted. Furthermore, other cases may be configured or indicated with other configurations.
