[0020] It will be readily appreciated that the components of certain example embodiments as generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations. The following is a detailed description of some example embodiments of systems, methods, apparatus, and non-transient computer program products for time domain resource allocation of demodulation reference signals. For example, certain example embodiments may relate to time domain resource allocation of demodulation reference signals in sub-band full-duplex operation.

[0021] In NR, communications may be governed at least in part by physical layer control signaling of uplink (UL) and downlink (DL) transport channels, such as the physical downlink shared channel (PDSCH) and the physical uplink shared channel (PUSCH). The resources allocated for the PDSCH and PUSCH may be within the bandwidth part (BWP) of the carrier. The resources in the time domain for PDSCH and PUSCH transmissions may be scheduled by a downlink control information (DCI) format.

[0022] As described in the technical specifications of the Third Generation Partnership Project (3GPP), for PDSCH transmission, the time domain resource allocation of the PDSCH can be determined by the starting symbol index S in the time slot and the length L in symbols. Based on S and L, two PDSCH mapping types can be defined depending on whether a normal cyclic prefix or an extended cyclic prefix is ​​applied to orthogonal frequency division multiplexing (OFDM). For example, for normal cyclic prefix OFDM, a first mapping type (the first mapping type can be referred to as mapping type A) can define S as any value from 0 to 3, and can define the minimum value of L as 3. As another example, a second mapping type (the second mapping type can be referred to as mapping type B) can define S as any value from 0 to 12, and can define L as any value from 2 to 13.

[0023] For PUSCH transmission, similar to PDSCH transmission, 3GPP describes that two PUSCH mapping types can be defined based on S and L and whether a normal cyclic prefix or an extended cyclic prefix is ​​applied to OFDM applications. For example, for normal cyclic prefix OFDM, a first mapping type (the first mapping type may be referred to as mapping type A) may define S to always be 0, and may define the minimum value of L to be 4. As another example, a second mapping type (the second mapping type may be referred to as mapping type B) may define S to be any value from 0 to 13, and may define L to be any value from 1 to 14.

[0024] According to 3GPP, when establishing PDSCH and / or PUSCH, as part of demodulation, a demodulation reference signal (DM-RS) may be used for channel estimation. For PDSCH, each position of one or more reference symbols (which may be referred to as DM-RS symbol l) of the DM-RS in the PDSCH may be specified in 3GPP for different PDSCH duration l. d In addition, the OFDM symbol index l determined for the DM-RS position may be set relative to the start of each PDSCH.

[0025] For example, the position l of the first DM-RS symbol for PDSCH mapping type A 0 It may be defined by a higher layer parameter (eg, dmrs-TypeA-Position), and for the second DM-RS symbol for PDSCH mapping type B, l 0 = 0. Additionally, a radio resource control (RRC) parameter dmrs-AdditionalPosition in DRMS-DownlinkConfig may be used to configure whether one or more additional DM-RSs may be required.

[0026] The reference point position of the OFDM symbol index l and the position l of the first DM-RS symbol 0 It may be based on a mapping type, such as mapping type A or mapping type B discussed above. As an example for PDSCH mapping type A, l may be defined relative to the start of a slot, and l 0 = 3 may be defined when a higher layer parameter (such as dmrs-TypeA-Position) indicates that the position is set equal to 3. When the position indicated by the higher layer parameter (such as dmrs-TypeA-Position) is not equal to 3, l 0 =2, in this example, l d The duration between the first OFDM symbol of a slot and the last OFDM symbol of the scheduled PDSCH resources in the slot may be defined.

[0027] This example based on 3GPP for PDSCH mapping type A can be further defined: only when dmrs-TypeA-Position is equal to position "pos2", dmrs-AdditionalPosition can be equal to position "pos3". When dmrs-TypeA-Position is equal to position "pos2", the duration between the first OFDM symbol and the last OFDM symbol can be set to l d =3 and l d = 4 symbols. For single-symbol DM-RS, unless higher-layer parameters lte-CRS-ToMatchAround, lte-CRS-PatteryList1 or lte-CRS-PatteryList2 are configured; higher-layer parameter dmrs-AdditionalPosition is equal to 'pos1' and l 0 =3; and the UE indicates the capability for additionalDMRS-DL-Alt, otherwise l 1 =11. When these conditions are met, l 1 =12.

[0028] As an example for PDSCH mapping type B, l may be defined relative to the start of the scheduled PDSCH resource and l 0 =2. In this example, l d It can be the duration of the scheduled PDSCH resource and can be used by the UE to determine whether or when the additional one or more DM-RS symbols will be received by the UE. d ∈{2,3,4,5,6,7,8,9,10,11,12,13} OFDM symbols or for extended cyclic prefix, l d∈{2,4,6} OFDM symbols, and the front-loaded DM-RS allocated by the PDSCH collides with the resources reserved for the search space set associated with the CORESET, l can be increased so that the first DM-RS symbol occurs immediately after the CORESET and until no collision with any CORESET occurs.

[0029] In addition, if the PDSCH duration is l d is 2 symbols, the UE may not expect to receive DM-RS symbols beyond the second symbol. As another example, if the PDSCH duration is l d If the PDSCH duration is 5 symbols and there is an additional single-symbol DMRS, then when the current DM-RS symbol is in the first symbol of the PDSCH duration, the UE may expect the additional DM-RS to be transmitted on the fifth symbol. Otherwise, the UE may expect the additional DM-RS not to be transmitted.

[0030] As another example, when the PDSCH duration is l d When it can be 7 symbols for a normal cyclic prefix or 6 symbols for an extended cyclic prefix and an additional single-symbol DM-RS is configured, the UE may expect the additional DM-RS to be transmitted on the fifth symbol or the sixth symbol when the current DM-RS symbol is in the first symbol or the second symbol of the PDSCH duration, respectively. Otherwise, the UE may expect the additional DM-RS not to be transmitted.

[0031] Some additional examples of PDSCH durations may include: d ∈{5,6,7,8,9,10,11,12,13} OFDM symbols, the UE may not expect to receive DM-RS forwarded beyond the fourth symbol. d If the PDSCH duration is 12 or 13 symbols, the UE may not expect to receive DM-RS mapped to symbol 12 or later in the slot. d For all values ​​of d -1) symbol. If the PDSCH duration is l d Less than or equal to 4 OFDM symbols, only single-symbol DM-RS can be supported. If higher layer parameters lte-CRS-ToMatchAround, lte-CRS-PatteryList1 or lte-CRS-PatteryList2 are configured, where for normal cyclic prefix, PDSCH duration l d= 10; subcarrier spacing configuration μ = 0; single-symbol DM-RS is configured and at least one PDSCH DM-RS symbol in the PDSCH allocation collides with a symbol containing a resource element indicated by the higher layer parameters lte-CRS-ToMatchAround, lte-CRS-PatteryList1 or lte-CRS-PatteryList2, then Can be incremented by 1 in all time slots.

[0032] As described above, the PUSCH can be configured similarly to the PDSCH. In the PUSCH, the position of one or more DM-RS symbols l in the PUSCH can be based on the different PUSCH durations l. d The OFDM symbol index l determined for the DM-RS position can be defined relative to the start of each PUSCH. For example, the position l of the first DM-RS symbol in PUSCH mapping type A 0 It may be defined by a higher layer parameter dmrs-TypeA-Position, and for another example (such as PUSCH mapping type B), l 0 = 0 may be defined. The RRC parameter dmrs-AdditionalPosition in DMRS-UplinkConfig may be used to configure whether additional DM-RS is required. For PUSCH repetition type A, the DM-RS position of each slot may be the same across repetitions.

[0033] Similar to PDSCH, in PUSCH, the reference point of OFDM symbol index l and the position of the first DM-RS symbol l 0 It may be based on a mapping type, such as mapping type A or mapping type B discussed above. As an example for PUSCH mapping type A, if frequency hopping is disabled, then l may be defined relative to the start of a slot, and if frequency hopping is enabled, then l may be defined relative to the start of each hop. 0 = 3 may be defined by a higher layer parameter (eg, dmrs-TypeA-Position).

[0034] In another example for mapping type B, if frequency hopping is disabled, l may be defined relative to the start of the scheduled PUSCH resources, and if frequency hopping is enabled, l may be defined relative to the start of each hop, and l 0 =3 can be set.

[0035] Similar to PDSCH, for PUSCH, each position of DM-RS symbol l can be based on, for example, PUSCH duration l dSome examples of PUSCH durations may include: when intra-slot frequency hopping is not used, d It can be the duration between the first OFDM symbol of a slot and the last OFDM symbol of a scheduled PUSCH resource in the slot. Alternatively, if intra-slot frequency hopping is not used, then l d is the duration of the scheduled PUSCH resources for PUSCH mapping type B. As another alternative, if intra-slot frequency hopping is not used, then l d is the duration of each hop.

[0036] In addition, if the higher layer parameter maxLength in DMRS-UplinkConfig is not configured, or for msgA transmission, msgA-MaxLength in msgA-DMRS-Config is not configured, a single symbol DM-RS may be used. If the higher layer parameter maxLength in DMRS-UplinkConfig is equal to 'len2', the associated downlink control information (DCI) or the configured grant configuration may be used to determine whether single or dual symbol DM-RS may be used. If the higher layer parameter msgA-MaxLength in msgA-DMRS-Config is equal to 'len2', dual symbol DM-RS may be used. If the higher layer parameter dmrs-AdditionalPosition is not set to 'pos0' and intra-slot hopping is performed by higher layers, the 3GPP standard may be used, which assumes that for each hop, dmrs-AdditionalPosition is equal to 'pos1'. For PUSCH mapping type A, dmrs-AdditionalPosition may be equal to position "pos3" only when dmrs-TypeA-Position is equal to position "pos2". When dmrs-TypeA-Position is equal to position "pos2", the duration between the first OFDM symbol and the last OFDM symbol may be set to l d =4 symbols.

[0037] To facilitate transmission, the modulation symbols and / or reference signals may be converted into a waveform, which is a baseband signal, before the baseband signal is mixed to a radio frequency (RF) and transmitted. The waveform may be cyclic prefix orthogonal frequency division multiplexing (CP-OFDM) (which may be applicable to both uplink and downlink) or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM) (which may be applicable only to uplink). DFT-s-OFDM may support only a single transmission layer for each user (rank = 1), and CP-OFDM may support more than one layer (rank ≥ 1). This may allow CP-OFDM to provide higher throughput and capacity than DFT-s-OFDM. In contrast, DFT-s-OFDM may have a relatively low peak-to-average power ratio (PAPR), which may allow DFT-s-OFDM to be used with higher transmission power to provide relatively improved coverage.

[0038] DFT-s-OFDM can be generated by adding a transform precoding block before the processing block used to generate CP-OFDM. The transform precoding block can be a fast Fourier transform (FFT) block that converts a time domain signal into a frequency domain signal. Due to the transform precoding block used in the transmitter, the waveform can be configured separately so that the receiver can perform an inverse operation (IFFT).

[0039] PUSCH and PDSCH transmissions may be separated by duplexing in time and / or frequency. Time division duplexing (TDD) may allow uplink (PUSCH) transmissions and downlink (PDSCH) transmissions to use the same carrier frequency and be separated only in time. Frequency division duplexing (FDD) may allow uplink (PUSCH) transmissions and downlink (PDSCH) transmissions to use different frequencies and occur substantially simultaneously, e.g., simultaneously or substantially simultaneously.

[0040] It may be beneficial to allow simultaneous DL and UL transmissions on different physical resource blocks (PRBs) (which may be referred to as subbands) within an unpaired wideband NR cell. This may be referred to as subband non-overlapping full duplex (SBFD). For example, Figure 1 An example of frequency-time resource partitioning with SBFD compared to FDD and TDD is shown.

[0041] Figure 2 Examples of SBFD time slots that can be defined for both non-overlapping DL subbands and UL subbands and non-SBFD time slots (e.g., legacy or full DL / UL time slots) that can be defined so that the entire frequency band can be used for DL ​​or UL are shown. The SBFD time slots can be known by the UE, which can be referred to as a SBFD-aware UE.

[0042] Figure 3 An example of co-channel interference in a deployment of SBFD is shown. SBFD may provide cross-link interference (CLI), such as co-channel inter-subband CLI and co-channel intra-subband CLI. Co-channel inter-subband CLI may be classified as base station (such as gNB) interference, intra-cell UE-to-UE co-channel inter-subband CLI, inter-cell UE-to-UE co-channel inter-subband CLI, and / or gNB-to-gNB co-channel inter-subband CLI. Co-channel intra-subband CLI may be classified as gNB-to-gNB inter-cell co-channel intra-subband CLI and / or UE-to-UE inter-cell co-channel intra-subband CLI.

[0043] like Figure 3 As shown, when performing UL transmission and DL transmission with a network entity 320 (e.g., a gNB, another UE, etc.), UE 310 may experience co-channel interference. Figure 3 As shown in the example of UL transmission in one or more time slots of SBFD, interference "1" can be gNB self-interference, interference "4" can be gNB to gNB co-channel inter-subband CLI, and interference "5" can be gNB to gNB inter-cell co-channel intra-subband CLI. Figure 3 In the example of DL transmission in the SBFD time slot shown in , interference "2" can be intra-cell UE-to-UE co-channel inter-subband CLI, interference "3" can be inter-cell UE-to-UE co-channel inter-subband CLI, and interference "6" can be UE-to-UE inter-cell co-channel intra-subband CLI.

[0044] In order to reduce the CLI in the time slots for SBFD discussed above, one or more additional DM-RS symbols may be added in the PDSCH / PUSCH transmissions in the time slots for SBFD compared to the time slots for non-SBFD. Adding one or more additional DM-RS symbols may improve the performance of transmissions in the time slots for SBFD via improved channel estimation. Additionally or alternatively, a lower power-to-average ratio (PAPR) waveform is provided for PUSCH transmissions in the time slots for SBFD (e.g., DFT-s-OFDM) compared to the time slots for non-SBFD (e.g., OFDM). The lower PAPR may improve the performance of transmissions in the time slots for SBFD by enabling the UE to use the maximum transmit power of the UE. Thus,

[0045] As discussed in detail below, various exemplary embodiments may provide several technical improvements, enhancements and / or advantages, including, for example, providing a framework for indicating and determining different DM-RS symbol allocations and / or different waveforms for transmissions on SBFD and non-SBFD time slots.

[0046] Figure 42 shows an exemplary signal diagram according to various exemplary embodiments. Specifically, Figure 4 An exemplary signal diagram is shown for a UE 401 and a network entity (NW) 402 (such as a gNB) to determine one or more different DM-RS symbol allocations and / or different waveforms for transmissions on SBFD timeslots and non-SBFD timeslots.

[0047] At 410, NW 402 may indicate and provide (i) a frequency band, (ii) a number of time slots / symbols (such as SBFD time slots / symbols) in which the frequency band is split into a number of sub-bands, and the positions of the number of time slots / symbols in a radio frame, and (iii) a number of time slots / symbols (such as non-SBFD time slots / symbols) in which the entire frequency band may be used for DL ​​transmission or UL transmission, and the positions of the number of time slots / symbols in a radio frame. The frequency band may be split into a number of sub-bands, and may include at least one sub-band for DL ​​transmission and at least one sub-band for UL transmission.

[0048] At 415, UE 401 can receive a frequency band, multiple time slots / symbols, in which the frequency band is split into multiple sub-bands, and multiple time slots / symbols from NW 402, and the entire frequency band can be used for DL ​​transmission or UL transmission in the multiple time slots / symbols, as indicated by NW 402.

[0049] At 420, NW 402 may indicate and provide a first configuration and a second configuration of a time domain resource allocation of a reference signal (e.g., DM-RS) and / or a UE operating mode (e.g., a waveform). The second configuration may be used for transmissions in SBFD slots / symbols. For example, the second configuration of the time domain resource allocation of the DM-RS may require the UE 401 to transmit an UL transmission (such as a PUSCH) or receive a DL transmission (such as a PDSCH) in a SBFD slot / symbol having a higher number of DM-RS symbols than when the first configuration is used. In another example, the second configuration (i.e., one or more waveforms) of the UE operating mode may require the UE 401 to transmit an UL transmission (e.g., a PUSCH) in a SBFD slot / symbol having a waveform that is more robust to an interfered channel (e.g., DFT-s-OFDM) than the first configuration. The first configuration may require the UE 401 to transmit using another waveform (such as CP-OFDM).

[0050] At 425 , UE 401 may receive a first configuration and a second configuration from NW 402 .

[0051] At 430, NW 402 may schedule a transmission. According to certain exemplary embodiments, the transmission may be on a SBFD slot / symbol, or on a non-SBFD slot / symbol, or may span a SBFD slot / symbol and a non-SBFD slot / symbol. For example, a transmission on a SBFD slot / symbol or on a non-SBFD slot / symbol may be a PDSCH or PUSCH with or without repetition. In another exemplary embodiment, a transmission spanning a SBFD slot / symbol and a non-SBFD slot / symbol may be a PDSCH or PUSCH with repetition.

[0052] At 440, UE 401 may determine a time domain resource allocation for a reference signal and / or a UE operation mode. According to certain exemplary embodiments, the determination by UE 401 may be based at least on a time domain allocation for a scheduled transmission, a location of SBFD time slots / symbols and non-SBFD time slots / symbols, and a first configuration and a second configuration.

[0053] In a first example, when a transmission is fully scheduled on a non-SBFD time slot / symbol, the time domain resource allocation of reference signals to be applied to the transmission and / or the UE operation mode may be based on a first configuration. When a transmission is fully scheduled on a SBFD time slot / symbol, the time domain resource allocation of reference signals to be applied to the transmission and / or the UE operation mode may be based on a second configuration. When a transmission spans SBFD time slots / symbols and non-SBFD time slots / symbols, the time domain resource allocation of reference signals and / or the UE operation mode may be based on a first configuration for a portion of the transmission that overlaps with a non-SBFD time slot / symbol, and based on a second configuration for a portion of the transmission that overlaps with a non-SBFD time slot / symbol.

[0054] In a second example, the determination of the time domain resource allocation may be based on a first configuration. When the transmission is fully scheduled on a non-SBFD time slot / symbol, the time domain resource allocation of the reference signal to be applied to the transmission and / or the UE operation mode may be based on the first configuration. When the transmission is fully scheduled on a SBFD time slot / symbol, the time domain resource allocation of the reference signal and / or the UE operation mode may be based on the first configuration scaled by at least one offset value.

[0055] As an example in the time domain resource allocation of the reference signal, the candidate values ​​of dmrs-AdditionalPosition may be defined as "pos0", "pos1", "pos2" and / or "pos3". Assuming that the first configuration may be configured as "pos0" for dmrs-AdditionalPosition, and assuming that the offset value is 2, the UE 401 may determine the allocation of one or more DM-RS symbols. For example, the determination may be made by applying the offset value to the index of the candidate value for dmrs-AdditionalPosition, such as dmrs-AdditionalPosition may have a value "pos2" for determining one or more DM-RS symbol positions for transmission. Another example in the time domain resource allocation of the reference signal assumes that the first configuration may be configured as "pos0" for dmrs-AdditionalPosition, and assuming that the offset value may be set to 4. In this example, the UE 401 may determine the allocation of one or more DM-RS symbols by using dmrs-AdditionalPosition = pos0, and applying the offset value in symbols and referring to the first DM-RS symbol position or the last DM-RS symbol position as determined. Thus, at least one symbol in a transmission may be determined, wherein at least one additional DM-RS symbol may be allocated in the at least one symbol.

[0056] The example in the time domain resource allocation of the UE operation mode may assume that the candidate waveforms for transmission may be configured or specified as a list. For example, {CP-OFDM}, {DFT-s-OFDM}, {DFT-s-OFDM with frequency domain spectral shaping (FDSS)}, {DFT-s-OFDM with FDSS and spectrum spreading}. The example in the time domain resource allocation of the UE operation mode may also assume that the first configuration may be configured for CP-OFDM, such as associated with index 0 in the list, and assume that the offset value is 2. In some exemplary embodiments, the UE 401 may determine the waveform for transmission by applying the offset value to the index of the waveform candidate, such as {DFT-s-OFDM with FDSS}.

For example, in some exemplary embodiments, it may be possible to enhance the performance (e.g., reliability) of transmissions in SBFD slots / symbols by using additional DM-RS symbols or by using lower PAPR waveforms (such as DFT-s-OFDM). By using one or more additional DM-RS symbols for transmissions in SBFD slots / symbols, various exemplary embodiments may improve channel estimation / frequency offset estimation to overcome CLI, and / or improve signal-to-noise ratio (SNR) due to improved channel estimation.

[0087] Certain exemplary embodiments further provide advantages by using a DFT-s-OFDM waveform for transmission on SBFD slots / symbols, such as providing additional capacity for UL power boost due to lower PAPR compared to CP-OFDM counterparts. This can be useful when the UE suffers from UL power limitations and can be able to provide up to 1 dB of gain. Some exemplary embodiments can also provide lower throughput due to the maximum number of multiple-input multiple-output (MIMO) layers (rank) supported by DFT-s-OFDM, which can be set to 1. This allows switching back to CP-OFDM to support higher ranks in non-SBFD slots / symbols, which provides improved throughput.
