[0014] It will be readily understood that the components of certain example embodiments, as generally described and illustrated herein, can be arranged and designed in a wide variety of different configurations. Following are detailed descriptions of several example embodiments of systems, methods, apparatuses, and non-transitory computer program products for time-domain resource allocation of demodulation reference signals. For example, some example embodiments may be directed to time-domain resource allocation of demodulation reference signals in sub-band full-duplex operation.

[0015] In NR, communications may be managed 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 physical uplink shared channel (PUSCH). The resources allocated for the PDSCH and PUSCH may be within the bandwidth portion (BWP) of a carrier. Resources in the time domain for PDSCH and PUSCH transmissions may be scheduled by a downlink control information (DCI) format.

[0016] As described in the 3GPP (3rd Generation Partnership Project) technical specifications, for PDSCH transmission, the time domain resource allocation for the PDSCH may be determined by the starting symbol index S within a slot and the length L in symbols. Based on S and L, two PDSCH mapping types may be defined depending on whether a normal cyclic prefix or an extended cyclic prefix is ​​applied for orthogonal frequency division multiplexing (OFDM). For example, for normal cyclic prefix OFDM, a first mapping type, sometimes referred to as mapping type A, may define S as any value between 0 and 3, and may define the minimum value of L as 3. As another example, a second mapping type, sometimes referred to as mapping type B, may define S as any value between 0 and 12, and may define L as any value between 2 and 13.

[0017] For PUSCH transmission, similar to PDSCH transmission, 3GPP defines two PUSCH mapping types that can be defined based on S and L, and whether a normal cyclic prefix or an extended cyclic prefix is ​​applied for OFDM. For example, for normal cyclic prefix OFDM, a first mapping type, sometimes referred to as mapping type A, can define S as always 0 and the minimum value of L as 4. As another example, a second mapping type, sometimes referred to as mapping type B, can define S as any value between 0 and 13 and L as any value between 1 and 14.

[0018] According to 3GPP, when establishing a PDSCH and / or a PUSCH, a demodulation reference signal (DM-RS) may be used for channel estimation as part of the demodulation. In the case of a PDSCH, the DM-RS symbols in the PDSCH

number

[0019] For example, the position l0 of the first DM-RS symbol of PDSCH mapping type A may be defined by a higher layer parameter (e.g., dmrs-TypeA-Position), and the position l0 of the second DM-RS symbol of PDSCH mapping type B may be 0. Furthermore, the radio resource control (RRC) parameter dmrs-AdditionalPosition of DMRS-DownlinkConfig may be used to configure whether one or more additional DM-RSs are required.

[0020] The reference point position of OFDM symbol index l and the position l0 of the first DM-RS symbol may be based on the mapping type, such as mapping type A or mapping type B described above. As an example of PDSCH mapping type A, l may be defined relative to the start of the slot, and l0=3 may be defined when higher layer parameters such as dmrs-TypeA-Position indicate a position that is set equal to 3. If the higher layer parameters such as dmrs-TypeA-Position indicate a position that is not 3, then l0=2. In this example, l d , may define the duration between the first OFDM symbol of a slot and the last OFDM symbol of a scheduled PDSCH resource within the slot.

[0021] This example based on 3GPP for PDSCH mapping type A may further define that dmrs-AdditionalPosition can be equal to position "pos3" only when dmrs-TypeA-position is equal to position "pos2". The duration between the first and last OFDM symbols is l when dmrs-TypeA-Position is equal to position "pos2". d =3 and l d = 4 symbols. For single-symbol DM-RS, l1 = 11 unless the higher layer parameters lte-CRS-ToMatchArround, lte-CRS-PatternList1, or lte-CRS-PatternList2 are set, the higher layer parameter dmrs-AdditionalPosition is equal to "pos1", l0 = 3, and the UE indicates the capability of an additional dmrs-DL-Alt. If these conditions are met, then l1 = 12.

[0022] As an example of PDSCH mapping type B, l may be defined relative to the start of the scheduled PDSCH resource, where l = 2. In this example, l dPDSCH duration l may be the duration of the scheduled PDSCH resource and may be used by the UE to determine if or when one or more additional DM-RS symbols are received by the UE. d but for normal cyclic prefix

number

number

number

[0023] Additionally, the PDSCH duration l d For example, if PDSCH duration l is 2 symbols, the UE may not expect to receive DM-RS symbols beyond the second symbol. d is 5 symbols and one additional single-symbol DMRS is configured, the UE may expect the additional DM-RS to be transmitted on the fifth symbol when the frontloaded DM-RS symbol is within the first symbol of the PDSCH duration. Otherwise, the UE may expect the additional DM-RS not to be transmitted.

[0024] As a further example, the PDSCH duration l dmay be 7 symbols for the normal cyclic prefix or 6 symbols for the extended cyclic prefix, and when one additional single-symbol DM-RS is configured, the UE may expect the additional DM-RS to be transmitted on the 5th or 6th symbol in the PDSCH duration when the frontloaded DM-RS symbol is in the 1st or 2nd symbol, respectively. Otherwise, the UE may expect the additional DM-RS not to be transmitted.

[0025] Some further examples of PDSCH duration are: PDSCH duration l d but,

number

[0026] The PUSCH may be configured similarly to the PDSCH, as described above. In the PUSCH, one or more DM-Rs symbols in the PUSCH

number

[0027] Similar to the PUSCH, in the PUSCH, the reference point of the OFDM symbol index l and the position l of the first DM-RS symbol 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, l is defined relative to the start of the slot when frequency hopping is disabled, and relative to the start of each hop when frequency hopping is enabled. l=3 is defined by higher layer parameters such as dmrs-TypeA-Position.

[0028] In another example of mapping type B, if frequency hopping is disabled, l may be defined relative to the start of the scheduled PUSCH resource, and if frequency hopping is enabled, l may be defined relative to the start of each hop and l may be set to 0.

[0029] Similar to PDSCH, for PUSCH, DM-RS symbols

number

[0030] Also, if the upper layer parameter MaxLength in DMRS-UplinkConfig is not set, or if the msgA transmission msgA-MaxLength in msgA-DMRS-Config is not set, a single-symbol DM-RS can be used. If the upper layer parameter maxLength in DMRS-UplinkConfig is equal to 'len2', the associated downlink control information (DCI) or configured grant configuration can be used to determine whether a single-symbol or double-symbol DM-RS can be used. If the upper layer parameter msgA-MaxLength in msgA-DMRS-Config is equal to 'len2', a double-symbol DM-RS can be used. If the upper layer parameter dmrs-AdditionalPosition is not set to 'pos0' and intra-slot frequency hopping is by upper layers, the 3GPP standard can be used, assuming dmrs-AdditionalPosition is equal to 'pos1' for each hop. For PUSCH mapping type A, dmrs-AdditionalPosition can be equal to position "pos3" only when dmrs-TypeA-position is equal to position "pos2". The duration between the first and last OFDM symbols is l when dmrs-TypeA-Position is equal to position "pos2". d = 4 symbols

[0031] To facilitate transmission, modulation symbols and / or reference signals may be converted into a waveform that is a baseband signal before the baseband signal is mixed into radio frequency (RF) and transmitted. The waveform may be cyclic prefix orthogonal frequency division multiplexing (CP-OFDM), which may be applicable to both the uplink and downlink, or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM), which may be applicable only to the uplink. DFT-s-OFDM may support only a single transmission layer (rank = 1) per user, while CP-OFDM may support multiple layers (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 transmit power to provide relatively improved coverage.

[0032] 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 the time-domain signal to a frequency-domain signal. With the transform precoding block used in the transmitter, the waveform can be separately configured so that the receiver can perform the inverse operation (IFFT).

[0033] PUSCH and PDSCH transmissions may be separated by duplexing in time and / or frequency. Time division duplexing (TDD) may allow uplink, PUSCH, and downlink, PDSCH transmissions to use the same carrier frequency and be separated only by time. Frequency division duplexing (FDD) may allow uplink, PUSCH, and downlink, PDSCH transmissions to use different frequencies and occur substantially simultaneously, such as simultaneously or substantially simultaneously.

[0034] In an unpaired wideband NR cell, it may be beneficial to allow simultaneous DL and UL transmissions on different physical resource blocks (PRBs), sometimes called subbands. This is sometimes called subband non-overlapping full duplex (SBFD). For example, Figure 1 shows an example of frequency-time resource partitioning with SBFD compared to FDD and TDD.

[0035] 2 shows examples of SBFD slots that may be defined for both non-overlapping DL and UL subbands, and non-SBFD slots that may be defined such that the entire band may be used for DL ​​or UL, e.g., legacy or full DL / UL slots. SBFD slots may be known by UEs, which may be referred to as SBFD-aware UEs.

[0036] Figure 3 shows an example of co-channel interference in a SBFD deployment. SBFD can provide crosslink interference (CLI), such as co-channel inter-subband CLI and co-channel inter-subband CLI. Co-channel inter-subband CLI can be classified as gNB, base station interference, such as intra-cell UE-UE co-channel inter-subband CLI, inter-cell UE-UE co-channel inter-subband CLI, and / or gNB-gNB co-channel inter-subband CLI. Co-channel intra-subband CLI can 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.

[0037] As shown in Figure 3, the UE 310 may experience co-channel interference when performing UL and DL transmissions with a network entity 320, such as a gNB, another UE, etc. As an example of UL transmissions in one or more slots of the SBFD shown in Figure 3, interference "1" may be gNB self-interference, interference "4" may be gNB-to-gNB co-channel inter-subband CLI, and interference "5" may be gNB-to-gNB co-channel intra-subband CLI. As an example of DL transmissions in the SBFD slots shown in Figure 3, interference "2" may be intra-cell UE-UE co-channel inter-subband CLI, interference "3" may be inter-cell UE-UE co-channel inter-subband CLI, and interference "6" may be inter-UE inter-cell co-channel intra-subband CLI.

[0038] To reduce CLI in slots for SBFD as discussed above, one or more additional DM-RS symbols may be added to PDSCH / PUSCH transmissions in SBFD slots compared to non-SBFD slots. Adding one or more additional DM-RS symbols may improve performance of transmissions in SBFD slots through improved channel estimation. Additionally or alternatively, a lower power-to-average ratio (PAPR) waveform for PUSCH transmissions in SBFD slots, e.g., DFT-s-OFDM, is a lower power-to-average ratio (PAPR) waveform compared to non-SBFD slots, e.g., OFDM. The lower PAPR may improve performance of transmissions in SBFD slots by allowing the UE to use its maximum transmit power.

[0039] As described 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 slots.

[0040] 4 illustrates an example signal diagram 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 transmission on SBFD and non-SBFD slots, in accordance with various exemplary embodiments.

[0041] At 410, the NW 402 may indicate and provide (i) a frequency band, (ii) a number of slots / symbols into which the frequency band is divided into multiple subbands, such as SBFD slots / symbols and the location of the number of slots / symbols in a radio frame, and (iii) a number of slots / symbols in which the entire frequency band, such as non-SBFD slots / symbols, may be used for DL ​​transmission or UL transmission, and the location of the number of slots / symbols in a radio frame. The frequency band may be divided into multiple subbands and may include at least one subband for DL ​​transmission and at least one subband for UL transmission.

[0042] At 415, UE 401 may receive from NW 402, as indicated by NW 402, a frequency band, a number of slots / symbols into which the frequency band is divided into multiple subbands, and a number of slots / symbols in which the entire frequency band may be used for DL ​​or UL transmission.

[0043] At 420, the NW 402 may indicate and provide a first configuration and a second configuration of a reference signal, e.g., a time-domain resource allocation for DM-RS, and / or a UE operation mode, e.g., a waveform. The second configuration may be used for transmission in SBFD slots / symbols. For example, the second configuration of the time-domain resource allocation for 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 an SBFD slot / symbol with a greater number of DM-RS symbols than when the first configuration is used. In another example, the second configuration of the UE operation mode (i.e., one or more waveforms) may require the UE 401 to transmit an UL transmission (e.g., a PUSCH) in an SBFD slot / symbol with a waveform that is more robust against interfered channels (e.g., DFT-s-OFDM) compared to the first configuration. The first configuration may require the UE 401 to transmit in a different waveform, such as CP-OFDM.

[0044] At 425, the UE 401 may receive the first configuration and the second configuration from the NW 402.

[0045] At 430, the NW 402 may schedule a transmission. According to some exemplary embodiments, the transmission may occur on an SBFD slot / symbol, or on a non-SBFD slot / symbol, or may span an SBFD slot / symbol and a non-SBFD slot / symbol. For example, a transmission on an SBFD slot / symbol or a non-SBFD slot / symbol may be a PDSCH or a PUSCH with or without repetition. In another exemplary embodiment, a transmission that spans an SBFD slot / symbol and a non-SBFD slot / symbol may be a PDSCH or a PUSCH with repetition.

[0046] At 440, the UE 401 may determine a time domain resource allocation for the reference signal and / or a UE operating mode. According to some example embodiments, the determination by the UE 401 may be based on at least the time domain allocation for scheduled transmissions, the locations of SBFD slots / symbols and non-SBFD slots / symbols, and the first and second configurations.

[0047] In a first example, when a transmission is scheduled entirely on non-SBFD slots / symbols, the reference signal time domain resource allocation and / or UE operating mode to be applied for the transmission may be based on a first configuration. When a transmission is scheduled entirely on SBFD slots / symbols, the reference signal time domain resource allocation and / or UE operating mode to be applied for the transmission may be based on a second configuration. When a transmission spans SBFD and non-SBFD slots / symbols, the reference signal time domain resource allocation and / or UE operating mode may be based on a first configuration for the portion of the transmission that overlaps with non-SBFD slots / symbols and a second configuration for the portion of the transmission that overlaps with SBFD slots / symbols.

[0048] In a second example, a determination of a time domain resource allocation may be based on a first configuration. When a transmission is scheduled entirely on non-SBFD slots / symbols, a time domain resource allocation of a reference signal to be applied for the transmission and / or a UE operating mode may be based on the first configuration. When a transmission is scheduled entirely on SBFD slots / symbols, a time domain resource allocation of a reference signal and / or a UE operating mode may be based on the first configuration scaled by at least one offset value.

[0049] As an example in time domain resource allocation of a reference signal, candidate values ​​of dmrs-AdditionalPosition may be defined as “pos0,” “pos1,” “pos2,” and / or “pos3.” Assume that a first configuration may be configured as “pos0” for dmrs-AdditionalPosition, and assume that the offset value is 2, then 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 of dmrs-AdditionalPosition, such as dmrs-AdditionalPosition may have the value “pos2” to determine one or more DM-RS symbol locations for transmission. As another example in time domain resource allocation of a reference signal, assume that a first configuration may be configured as “pos0” for dmrs-AdditionalPosition, and assume 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 apply an offset value with reference to the determined first or last DM-RS symbol location, on a symbol-by-symbol basis. Thus, at least one symbol during transmission to which at least one additional DM-RS symbol may be allocated may be determined.

[0050] An example of time domain resource allocation for a UE mode of operation may assume that candidate waveforms for transmission may be configured or specified as a list, such as {CP-OFDM}, {DFT-s-OFDM}, {DFT-s-OFDM with frequency domain spectrum shaping (FDSS)}, {DFT-s-OFDM with FDSS and spectrum extension}, etc. This example of time domain resource allocation for a UE mode of operation may also assume that a first configuration may be configured for CP-OFDM, such as associated with index 0 in the list, and an offset value may be 2. In some exemplary embodiments, the UE 401 may determine a waveform for transmission by applying an offset value to the index of the waveform candidate, such as {DFT-s-OFDM with FDSS}.

[0051] Continuing with the second example described above, when a transmission spans SBFD slots / symbols and non-SBFD slots / symbols, the reference signal time domain resource allocation and / or the UE operation mode may be based on a first configuration for the portion of the transmission that overlaps with the non-SBFD slots / symbols, and based on the first configuration scaled by at least one offset value for the portion of the transmission that overlaps with the SBFD slots / symbols.

[0052] At 450, when the transmission is a downlink transmission such as a PDSCH, the UE 401 may receive the transmission on the non-SBFD slots / symbols and / or SBFD slots / symbols scheduled by the NW 402 at 430. The UE 401 may receive the scheduled transmission using the determined time domain resource allocation of the reference signal and / or the UE operating mode.

[0053] At 460, when the transmission is an uplink transmission such as a PUSCH, the UE 401 may transmit scheduled transmissions on non-SBFD slots / symbols and / or SBFD slots / symbols to the NW 402 based on the determined time domain resource allocation of the reference signal and / or the UE operating mode.

[0054] 5 illustrates an exemplary flow diagram of a method according to various exemplary embodiments. In an exemplary embodiment, the method of FIG. 5 may be performed by a network element or a group of network elements in a 3GPP system, such as LTE or 5G-NR. For example, in an exemplary embodiment, the method of FIG. 5 may be performed by a UE similar to the apparatus 710 illustrated in FIG. 7.

[0055] According to various exemplary embodiments, the method of FIG. 5 may include, at 510, receiving, by the device, from a network entity, information regarding slots and symbols of a transmission to be scheduled, including a physical channel and a signal. The signal may include at least one reference signal. The information regarding slots and symbols may include at least slot and symbol types for one-way transmissions and slot and symbol types for two-way transmissions. At 520, the method may include receiving, by the device, time-domain resource allocation information for the signal and first and second configurations of a waveform of the transmission to be scheduled. The first and second configurations may have different symbol densities for the signal in the transmission to be scheduled or may have different waveforms of the transmission to be scheduled relative to each other. At 530, the method may include determining, by the device, a time-domain resource allocation for the waveform of the transmission to be scheduled and the signal based on at least the information regarding the slots and symbols and at least one of the first and second configurations.

[0056] According to some example embodiments, the slots and symbols may be at least one of sub-band full duplex and / or non-sub-band full duplex.

[0057] According to certain exemplary embodiments, when the slots and symbols are subband full duplex, the signal time domain resource allocation and waveform of the transmission to be scheduled may be determined based on the first configuration.

[0058] According to certain exemplary embodiments, when the slots and symbols are non-subband full duplex, the time domain resource allocation of the signal and the waveform of the to-be-scheduled transmission may be determined based on a first configuration. Furthermore, when the slots and symbols are subband full duplex, the time domain resource allocation of the signal and the waveform of the to-be-scheduled transmission may be determined based on a second configuration.

[0059] According to some example embodiments, when the slots and symbols include subband full duplex and non-subband full duplex, the time domain resource allocation of the signal and the waveform of the transmission to be scheduled may be determined based on both the first configuration and the second configuration.

[0076] According to various exemplary embodiments, the device 720 may include at least one processor 721 and at least one memory 722, as shown in Figure 7. The memory 722 may store instructions that, when executed by the processor 721, cause the device 720 to perform the method described above with respect to Figure 6.

[0077] In some demonstrative embodiments, an apparatus (e.g., apparatus 710 and / or 720) may include means for performing any of the methods, processes, or variations described herein. Examples of means may include one or more processors, memories, controllers, transmitters, receivers, and / or computer program code for causing the execution of operations.

[0078] According to some demonstrative embodiments, an apparatus (e.g., apparatus 710) may include at least one processor and at least one memory. The memory may store instructions that, when executed by the at least one processor, cause the apparatus to at least receive, from a network entity similar to apparatus 720, information regarding slots and symbols in a signal for transmission. The apparatus may be further caused to receive a first configuration and a second configuration of time-domain resource allocation information for the signal. The apparatus may also be configured to determine the time-domain resource allocation information of the signal based at least on the time-domain resource allocation of the scheduled transmission, the information regarding the slots and symbols, and at least one of the first configuration and the second configuration.

[0079] According to some demonstrative embodiments, an apparatus (e.g., apparatus 720) may include at least one processor and at least one memory.

The apparatus may further cause the apparatus to schedule transmissions in slots and symbols associated with the signal and to provide the scheduled transmissions to user equipment similar to apparatus 710.

[0080] The various exemplary embodiments described above may provide several technical improvements, enhancements, and / or advantages. For example, in some exemplary embodiments, it may be possible to increase the performance, e.g., reliability, of transmissions during SBFD slots / symbols by using additional DM-RS symbols or by using a lower PAPR waveform 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 the signal-to-noise ratio (SNR) due to the improved channel estimation.

[0081] Some exemplary embodiments further provide advantages by using a DFT-s-OFDM waveform for transmission on SBFD slots / symbols, which provides additional capacity for UL power boosting due to a lower PAPR compared to its CP-OFDM counterpart. This may be useful when a UE is subject to UL power limitations and may be able to provide up to 1 dB of gain. Some exemplary embodiments may also provide lower throughput due to the maximum number of multiple-input multiple-output (MIMO) layers (rank) supported by DFT-s-OFDM, which may be set as 1. This allows switching back to CP-OFDM to support a higher rank in non-SBFD slots / symbols, providing improved throughput.
