Description

PUSCH transmission and reception methods, apparatus, and communication systems Technical Field

[0001] This application relates to the field of communication technology. Background Technology

[0002] In traditional technologies, for Time Division Duplex (TDD) frequency bands, uplink transmission can only occur during uplink time periods. When limited or few uplink time periods are allocated, there will be problems such as small uplink coverage, small capacity, and large latency.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application.

[0004] Summary of the Invention

[0005] To improve uplink capacity and coverage, and reduce uplink latency, network devices in the TDD band can operate in full-duplex mode at certain times. For example, at these times, the network device can simultaneously receive and transmit on different frequency domain resources within the corresponding carrier of the TDD band. This operating mode is called, for example, Subband non-overlapping Full Duplex (SBFD), but is not limited to this.

[0006] On the other hand, the Physical Uplink Shared Channel (PUSCH) can be scheduled by Downlink Control Information (DCI) or Random Access Response (RAR) Uplink Grant (UL grant). However, even if the above operating modes are supported, there is still no solution for how the UE transmits the PUSCH.

[0007] To address at least one of the above-mentioned problems, embodiments of this application provide a PUSCH transmission and reception method, apparatus, and communication system.

" / " indicates "and / or," and this application is not limited thereto. Various embodiments of this application will be described below with reference to the accompanying drawings. These embodiments are merely exemplary and not intended to limit the scope of this application.

[0080] First aspect of the embodiments

[0081] This application provides a PUSCH transmission method, which is described from the perspective of the terminal device.

[0082] Figure 2 is a schematic diagram of a PUSCH transmission method according to an embodiment of this application. As shown in Figure 2, the method includes:

[0083] 201. The terminal device receives information for configuring a first frequency domain resource (UL subband) (configured for one or more SCSs) and / or information for configuring a second frequency domain resource (DL subband) (configured for one or more SCSs);

[0084] 202, the terminal device transmits a PUSCH scheduled or activated by (CBRA or CFRA in response to PRACH in CBRA or CFRA) RAR or (CRC scrambled by TC-RNTI or C-RNTI or MCS-RNTI or CS-RNTI) DCI in the (activated) uplink BWP.

[0085] The third frequency domain resources (UL usable PRBs) of the uplink BWP include / are determined to be the intersection of the first frequency domain resources and the uplink BWP (configured for the SCS of the uplink BWP).

[0086] It is worth noting that Figure 2 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 2 above.

[0087] In some embodiments, if the UE is not provided with information for configuring the third frequency domain resources of the UL BWP, and / or, for PUSCH (aka.Msg.3PUSCH(re)transmission) scrambled by TC-RNTI with RAR and / or CRC by (CBRA's) (or PRACH in response to CBRA's) PUSCH, and / or, for (contention-based) random access (PUSCH in process), and / or, when the UL BWP is an initial UL BWP, the third frequency domain resources (UL usable PRBs) of the uplink BWP include / are determined to be (configured for the SCS of the uplink BWP) the intersection of the first frequency domain resources with the uplink BWP.

[0088] In other cases, such as when the UE is provided with information for configuring the third frequency domain resources of the UL BWP and / or the PUSCH is a PUSCH scheduled in a manner different from that described above and / or the UL BWP is a non-initial UL BWP (or not an initial UL BWP), the third frequency domain resources of the uplink BWP are determined based on the information for configuring the third frequency domain resources of the uplink BWP.

[0089] In some embodiments, the uplink BWP is an initial UL BWP or other UL BWP (e.g., referred to as a non-initial UL BWP). For information on first frequency domain resources, third frequency domain resources, etc., please refer to the following embodiments.

[0090] In some embodiments, the terminal device may be an SBFD-aware device; however, this application is not limited thereto. For example, during the initial access procedure (from RRC_IDLE to RRC_Connected state, including CBRA) and / or the random access procedure (e.g., CBRA) and / or the RRCSetupComplete message and / or in the capability information, the terminal device indicates to the network device that the terminal device is an SBFD-aware device (SBFD-aware UE).

[0091] For example, during random access, the terminal device is indicated to be an SBFD-aware device via the RO and / or Msg3 used to send the preamble / PRACH. For instance, some ROs (first ROs, different from the second ROs described below) are not limited to use by SBFD-aware UEs (other UEs may also use them), while some ROs (second ROs, e.g., referred to as additional ROs, but not limited to them) are limited to use by SBFD-aware devices. Therefore, when a UE uses a second RO to send the preamble / PRACH, the base station knows that the UE is an SBFD-aware device (and consequently, the subsequent Msg3 and / or RRCSetupComplete message and / or capability information may include / not include information indicating that the UE is an SBFD-aware device). For example, (when a UE uses a first RO to send the preamble / PRACH,) the Msg3 and / or RRCSetupComplete message and / or capability information includes information indicating that the UE is an SBFD-aware device.

[0092] For example, an SBFD-aware UE has capabilities related to SBFD operation, including one or more of the following: being able to know the SBFD configuration, such as the configuration of the first time domain resources and / or the second time domain resources and / or the first frequency domain resources and / or the second frequency domain resources described below; being able to configure transmit and receive signals according to the SBFD; and being able to transmit uplink signals on (DL)SBFD symbols.

[0093] The following is an illustrative description of the time-domain resources involved in the embodiments of this application.

[0094] In some embodiments, for a cell or carrier, in the first time domain resources, different frequency domain resources are respectively (only) used for (network device receiving) uplink (e.g., corresponding to the first frequency domain resources described below) and (only) used for (network device transmitting) downlink (e.g., corresponding to the second frequency domain resources described below). For example, the network device can simultaneously receive (uplink signals) in the frequency domain resources (only) used for uplink and transmit (downlink signals) in the frequency domain resources (only) used for downlink. The second time domain resources are outside the first time domain resources. For example, in the second time domain resources, different frequency domain resources are all used for uplink or all used for downlink. That is, the frequency domain resources are not divided into frequency domain resources (only) used for uplink and (only) used for downlink, and the network device does not receive and transmit at the same time.

[0095] In some embodiments, the first time-domain resource includes, for example, SBFD time slots and / or SBFD symbols (or first symbols, or other names), and the second time-domain resource includes, for example, non-SBFD time slots and / or non-SBFD symbols (or second symbols, or other names). Here, SBFD time slots refer to time slots where all symbols are SBFD symbols, and non-SBFD time slots refer to time slots where all symbols are non-SBFD symbols. For ease of description, SBFD symbols and non-SBFD symbols will be used in the following description.

[0096] In some embodiments, information for configuring SBFD symbols and / or non-SBFD symbols is provided by higher-layer signaling. For example, higher-layer parameters for configuring SBFD symbols may optionally exist in SIB1 and / or the SIB ServingCellConfigCommonSIB IE and / or the ServingCellConfigCommon IE (within the ServingTDD-UL-DL-ConfigCommon IE, which contains the TDD-UL-DL-Pattern IE), and / or, higher-layer parameters for configuring SBFD symbols may optionally exist in the ServingCellConfig.

[0097] In some embodiments, a cell / carrier can be configured with one or more (e.g., two) TDD uplink / downlink patterns. When multiple patterns are configured, different patterns may or may not have corresponding SBFD symbols, and different patterns are independently configured with corresponding SBFD symbols.

[0098] For example, for each pattern with SBFD symbols, the configured SBFD symbols are continuous within the corresponding period of the pattern. The high-level parameters for configuring SBFD symbols mentioned above include, for example, one or more parameters for configuring SBFD symbols in that period, such as: start slot index, start symbol index (in the start slot), end slot index, and end symbol index (in the end slot).

[0099] For example, the start and end slots are the first and last slots containing SBFD symbols, respectively. The start and end symbols are the first and last SBFD symbols in the start slot and the last SBFD symbol in the end slot, respectively. All symbols from the start symbol of the start slot to the end symbol of the end slot are SBFD symbols. The slot index is the number of the slots included in the period, which increments by 1, for example, starting from 0 or 1. For example, when the start slot index is 0, the start slot is the first slot in the period; when the start slot index is 1, the start slot is the second slot in the period, and so on. Similarly, the symbol index is the number of the symbols within a slot. The aforementioned slots / symbols use the SCS configured in the reference subcarrier spacing field of the Common TDD Uplink / Downlink Configuration (TDD-UL-DL-Config Common) IE.

[0100] For example, each / different pattern is configured with a period independently, for example, by the corresponding ((TDD-UL-DL-Pattern)IE)dl-UL-TransmissionPeriodicity. When only one pattern is configured, the period of the SBFD symbol is the same as the period corresponding to that pattern; when multiple patterns (e.g., two) are configured, the period of the SBFD symbol is the same as the sum of the periods corresponding to all patterns.

[0101] In some embodiments, a downlink symbol is, for example, a symbol indicated as downlink by the first uplink / downlink configuration, an uplink symbol is, for example, a symbol indicated as uplink by the first uplink / downlink configuration, and a flexible symbol is, for example, a symbol that is neither indicated as downlink nor as uplink by the first uplink / downlink configuration, or a symbol indicated as flexible by the configuration. The first uplink / downlink configuration is used to provide cell-specific uplink / downlink configurations, such as tdd-UL-DL-ConfigurationCommon, or the common TDD uplink / downlink configuration (TDD-UL-DL-ConfigCommon)IE or (TDD-UL-DL-Pattern)IE, but is not limited thereto.

[0102] In some embodiments, the UE determines the DL / UL / Flexible symbol corresponding to the BWP based on the DL / UL / Flexible symbol configured according to the aforementioned reference Subcarrier Spacing (and assuming NCP). For example, it determines the DL / UL / Flexible symbol corresponding to the BWP based on the reference Subcarrier Spacing and the SCS and / or CP type (NCP or ECP) ​​of the BWP.

[0103] In some embodiments, the DL / UL / Flexible symbol refers to the DL / UL / Flexible symbol configured based on the reference SubcarrierSpacing or the DL / UL / Flexible symbol corresponding to the BWP.

[0104] In some embodiments, the UE determines the SBFD / non-SBFD symbol corresponding to the BWP based on the SBFD / non-SBFD symbol configured based on the aforementioned reference SubcarrierSpacing (and assuming NCP). For example, it determines the SBFD / non-SBFD symbol corresponding to the BWP based on the reference SubcarrierSpacing and the SCS and / or CP type (NCP or ECP) ​​of the BWP.

[0105] In some embodiments, SBFD / non-SBFD symbols refer to SBFD / non-SBFD symbols configured based on reference SubcarrierSpacing or SBFD / non-SBFD symbols corresponding to BWP.

[0106] In some embodiments, the UE does not expect the CP type of the BWP to be ECP.

[0107] In some embodiments, the UE does not expect the SBFD symbols configured (as described above by the higher-layer parameters) to overlap with the uplink symbols, or if the SBFD symbols configured (as described above by the higher-layer parameters) overlap with the uplink symbols, the UE considers the SBFD symbols overlapping with the uplink symbols to be non-SBFD symbols.

[0108] In some embodiments, the SBFD symbol overlaps with the downlink symbol or the flexible symbol, or the SBFD symbol is configured within the range of the downlink symbol and / or the flexible symbol.

[0109] In some embodiments, SBFD symbols include DLSBFD symbols and / or Flexible SBFD symbols, and non-SBFD symbols include Full-DL symbols and / or Full-Flexible symbols and / or Full-UL symbols (or UL symbols). Other representations may also be used for these symbols, and are not limited thereto.

[0110] Figure 3 is an example diagram of the time-domain resources of an embodiment of this application. As shown in Figure 3, a period may include multiple different symbols. Among them, the SBFD symbol is within the range of downlink symbols and flexible symbols. The SBFD symbol that overlaps with the DL symbol is represented as a DLSBFD symbol, the SBFD symbol that overlaps with the flexible symbol is represented as a Flexible SBFD symbol, the downlink symbol that does not overlap with the SBFD symbol is represented as a Full-DL symbol, the flexible symbol that does not overlap with the SBFD symbol is represented as a Full-Flexible symbol, and the UL symbol that does not overlap with the SBFD symbol is represented as a Full-UL symbol (assuming that the UL symbol cannot be used as an SBFD symbol, the Full-UL symbol is equivalent to the UL symbol). Figure 3 illustrates the time-domain resources of an embodiment of this application, but is not limited thereto.

[0111] The frequency domain resources involved in the embodiments of this application will be illustrated below.

[0112] For a cell and / or carrier, in the first time domain resources, the first frequency domain resources are used (only) for uplink and the second frequency domain resources are used (only) for downlink. That is, the frequency domain resources are divided into the first frequency domain resources used (only) for uplink and the second frequency domain resources used (only) for downlink. The second time domain resources are outside the first time domain resources, that is, in the second time domain resources, the frequency domain resources are not divided in the above manner.

[0113] For example, the first frequency domain resource includes the uplink subband (UL subband), and the second frequency domain resource includes the downlink subband (DL subband). Other names may also be used, and this is not a limitation. For convenience, the following descriptions will use UL subband and DL subband.

[0114] In some embodiments, the UE receives information for configuring the UL subband and DL subband. For example, the uplink subband and downlink subband each include an integer number of PRBs, and the information for configuring the UL subband and DL subband includes information indicating the corresponding starting PRB and bandwidth / size (including the number of PRBs).

[0115] In some embodiments, information for configuring the UL subband and DL subband is provided by higher-level signaling.

[0116] For example, the higher-layer parameters used to configure the DL subband may optionally exist in SIB1 (the SIB Public Service Cell Configuration (ServingCellConfigCommonSIB) IE (the SIB Common Downlink Configuration (DownlinkConfig Common SIB) IE (the SIB Downlink Frequency Domain Information (FrequencyInfoDL-SIB) IE (the SCS Specific Carrier (SCS-SpecificCarrier) IE))). For instance, the inclusion relationship of these parameters can be expressed as: SIB1 > ServingCellConfigCommonSIB > DownlinkConfigCommonSIB > FrequencyInfoDL-SIB > SCS-SpecificCarrier; and / or,

[0117] The higher-layer parameters used to configure the DL subband may optionally exist in the ServingCellConfigCommon IE (which contains the DownlinkConfigCommon IE, which contains the DownlinkFrequencyInfoDL IE, which contains the SCS-SpecificCarrier IE)). For example, the inclusion relationship of the above parameters can be represented as: ServingCellConfigCommon > DownlinkConfigCommon > FrequencyInfoDL > SCS-SpecificCarrier, and / or, optionally, in the ServingCellConfig. That is, the higher-layer parameters used to configure the DL subband may optionally exist in one or more of the above parameters.

[0118] For example, the higher-layer parameters used to configure the UL subband may optionally exist in SIB1 (the SIB ServingCellConfigCommonSIB IE, the SIB UplinkConfigCommonSIB IE, the SIB Uplink FrequencyInfoUL-SIB IE, and the SCS-SpecificCarrier IE). For instance, the inclusion relationship of these parameters can be expressed as: SIB1 > ServingCellConfigCommonSIB > UplinkConfigCommonSIB > FrequencyInfoUL-SIB > SCS-SpecificCarrier, and / or...

[0119] The higher-layer parameters used to configure the UL subband may optionally exist in the ServingCellConfigCommon IE (which contains the CommonUplinkConfigCommon IE, which contains the UplinkFrequencyInfoUL IE, which contains the SCS-SpecificCarrier IE)). For example, the inclusion relationship of the above parameters can be represented as: ServingCellConfigCommon > UplinkConfigCommon > FrequencyInfoUL > SCS-SpecificCarrier, and / or, optionally, in the ServingCellConfig. That is, the higher-layer parameters used to configure the UL subband may optionally exist in one or more of the above parameters.

[0120] In some embodiments, the high-level parameters for configuring the UL subband and the high-level parameters for configuring the DL subband include one or more parameters for providing the RIV (resource indication value) and / or (the SCS corresponding to the UL / DL subband), that is, indicating the starting RB (RB) of the UL subband and the DL subband respectively based on the RIV. start ) and bandwidth (including the number of RBs, L RBs )).

[0121] For example, resource indicator values ​​can be defined as shown in Table 1 below.

[0122] Table 1

[0123] For example, for DL / UL subband: assuming the following in Table 1 In addition, the first PRB (RB) start The minimum value (0 or 1) corresponding to the PRB can be determined as follows: The first PRB is the PRB determined by the corresponding subcarrierSpacing and offsetToCarrier in ServingCellConfigCommon / ServingCellConfigCommonSIB (configured in the corresponding SCS-SpecificCarrier in FrequencyInfoDL (for DL ​​subband) / FrequencyInfoUL (for UL subband) / FrequencyInfoUL-SIB (for UL subband) / FrequencyInfoDL-SIB (for DL ​​subband)).

[0124] In some embodiments, within a cell, the scs-SpecificCarrierList of UL and DL may each include one or more SCS-SpecificCarrier IEs, and each SCS-SpecificCarrier IE corresponds to / includes one SCS configuration (subcarrierSpacing). That is, the scs-SpecificCarrierList of UL and DL may each include one or more SCS configurations.

[0125] For example, each SCS configuration in the UL scs-SpecificCarrierList is configured with a UL subband, or each corresponds to a UL subband, for example, each corresponds to an independent high-level parameter mentioned above for configuring the UL subband. Each SCS configuration in the DL scs-SpecificCarrierList is configured with one or more (e.g., two) DL subbands, or each corresponds to one or more DL subbands, for example, each corresponds to an independent high-level parameter mentioned above for configuring the DL subband. If an SCS configuration is configured with multiple DL subbands, the corresponding high-level parameter for configuring the DL subband includes multiple RIVs mentioned above.

[0126] In some embodiments, the UE does not expect the DL subband and UL subband (in the frequency domain) to overlap (for the same SCS (configuration), or the UE expects the DL subband and UL subband (in the frequency domain) not to overlap (for the same SCS (configuration)).

[0127] In some embodiments, a first time-domain resource, a first frequency-domain resource, and / or a third frequency-domain resource (UL usable PRBs for the active UL BWP) are used for uplink, and a second frequency-domain resource and / or a fourth frequency-domain resource (DL usable PRBs for the active DL BWP) are used for downlink, wherein the second time-domain resource is outside the first time-domain resource. For convenience, UL usable PRBs and DL usable PRBs will be used in the following description.

[0128] In some embodiments, for a UL BWP, its UL usable PRBs include / are determined as (in the SBFD symbol / corresponding to the SBFD symbol,) the intersection of (PRBs in the UL subband) and (PRBs in the uplink BWP) with (the SCS configured for the uplink BWP, or, corresponding to the SCS of the UL BWP), or, the PRBs in the intersection are referred to as UL usable PRBs.

[0129] For example, for a UL BWP, the intersection is determined based on the uplink subband corresponding to the SCS of that UL BWP. For instance, if the SCS of a UL BWP is 15kHz, then its corresponding UL available PRB is the intersection of that UL BWP and the corresponding uplink subband with SCS = 15kHz. If the SCS of a UL BWP is 30kHz, then its corresponding UL available PRB is the intersection of that UL BWP and the corresponding uplink subband with SCS = 15kHz.

[0130] In some embodiments, the UE does not expect the UL usable PRBs of the activated UL BWP and the DL usable PRBs of the activated DL BWP to overlap or their frequency domain spacing to be less than or greater than a specific value; or, the UE expects the UL usable PRBs of the activated UL BWP and the DL usable PRBs of the activated DL BWP to not overlap or their frequency domain spacing to be not less than or greater than a specific value.

[0131] Figure 4 is an example diagram of uplink usable PRBs according to an embodiment of this application. As shown in Figure 4, the UL BWP and UL subband overlap, and the UL usable PRBs are the intersection between them. The UL subband, for example, represents the uplink subband corresponding to the SCS of the UL BWP, but this application is not limited to this.

[0132] In some embodiments, for a DL BWP, its DL usable PRBs include / are determined as (in SBFD symbols / corresponding to SBFD symbols,) the intersection of (PRBs in the DL subband) and (PRBs in the downlink BWP) with (the SCS configured for the downlink BWP, or, corresponding to the SCS of the DL BWP), or, the PRBs in the intersection are referred to as DL usable PRBs.

[0133] For example, if a DL BWP has an SCS of 15kHz, then its corresponding DL can be represented by a PRB as the intersection of the DL BWP and the corresponding downlink subband with an SCS of 15kHz. If a DL BWP has an SCS of 30kHz, then its corresponding DL can be represented by a PRB as the intersection of the DL BWP and the corresponding uplink subband with an SCS of 15kHz.

[0134] Figure 5 is an example diagram of downlink usable PRBs according to an embodiment of this application. As shown in Figure 5, DL BWP and DL subband overlap, and DL usable PRBs are the intersection of the two. The DL subband, for example, represents the downlink subband corresponding to the SCS of the DL BWP, but this application is not limited thereto.

[0135] The above provides an illustrative description of time and frequency resources. The following provides an illustrative description of embodiments of this application.

[0136] In this embodiment of the application, PUSCH is sent in the (activated) uplink BWP.

[0137] For ease of description, the UL BWP where the PUSCH is located, is scheduled, or is sent will be referred to as the active UL BWP. An active UL BWP may be an initial UL BWP or a non-initial UL BWP.

[0138] In this application embodiment, the relationship between the activated UL BWP and the initial UL BWP is considered, including the following cases:

[0139] Case A: The activated UL BWP is the initial UL BWP.

[0140] Case B: The activated UL BWP is not the initial UL BWP, or the activated UL BWP is a non-initial UL BWP.

[0141] Case B-1: The activated UL BWP (the non-initial UL BWP mentioned above) and the initial UL BWP have the same SCS and the same CP length, and the activated UL BWP includes all RBs of the initial UL BWP;

[0142] Case B-2: The relationship between the activated UL BWP (the non-initial UL BWP mentioned above) and the initial UL BWP does not satisfy Case B-1, for example: the SCS of the activated UL BWP and the initial UL BWP are different, and / or, the CP lengths of the activated UL BWP and the initial UL BWP are different, and / or, the activated UL BWP does not include all RBs of the initial UL BWP.

[0143] In the embodiments of this application, overlap with the SBFD symbol includes partial overlap (i.e., the part is within the SBFD symbol and a part is within the non-SBFD symbol) and / or complete overlap (also, it can be said that it is within the SBFD symbol). Overlap with the non-SBFD symbol includes partial overlap (i.e., the part is within the non-SBFD symbol and a part is within the SBFD symbol) and / or complete overlap (also, it can be said that it is within the non-SBFD symbol).

[0144] In some embodiments, overlap with SBFD symbols and overlap with non-SBFD symbols do not both include the aforementioned partial overlap. For example, if overlap with SBFD symbols includes partial overlap, then overlap with non-SBFD symbols does not include partial overlap, and vice versa; this application is not limited thereto.

[0145] In this application embodiment, the relationship between the scheduled PUSCH and SBFD symbols and non-SBFD symbols is considered, including the following cases:

[0146] Case C: PUSCH and SBFD symbols (completely overlap).

[0147] Case D: PUSCH and non-SBFD symbols (completely overlap).

[0148] Case E:PUSCH overlaps with both SBFD and non-SBFD symbols.

[0149] In this application embodiment, the relationship between PUSCH and repetition is considered, including the following cases:

[0150] Case F: PUSCH does not have repeatability.

[0151] Case G:PUSCH has repetition.

[0152] In some embodiments, for Case G, Case C means that all repetitions of PUSCH completely overlap with the SBFD symbol, Case D means that all repetitions of PUSCH completely overlap with the non-SBFD symbol, and Case E means that at least some repetitions of PUSCH completely overlap with the SBFD symbol and at least some repetitions completely overlap with the non-SBFD symbol.

[0153] In this application embodiment, valid / invalid symbol types are considered, including the following cases:

[0154] Case H: One of the SBFD symbols and non-SBFD symbols is an invalid symbol (type), and the other is a valid symbol (type).

[0155] Case H-1: SBFD symbols are invalid symbols (type), and non-SBFD symbols are valid symbols (type).

[0156] Case H-2: Non-SBFD symbols are invalid symbols (type), while SBFD symbols are valid symbols (type).

[0157] Case I: There is no invalid symbol type, or both SBFD symbols and non-SBFD symbols are valid symbols (types).

[0158] In some embodiments, for Case H, it can also be said that PUSCH transmission is limited to SBFD symbols (when SBFD symbols are valid and non-SBFD symbols are invalid, Case H-2) or limited to non-SBFD symbols (when non-SBFD symbols are valid and SBFD symbols are invalid, Case H-1). For PUSCHs with repetitions, only the repetitions overlapping with SBFD symbols (for repetition Type B: actual) are transmitted, or only the repetitions overlapping with non-SBFD symbols (for repetition Type B: actual) are transmitted.

[0159] In this application embodiment, the downlink signal for scheduling / activating PUSCH is considered, including the following cases:

[0160] Case J: Scheduled by RAR (or RAR UL grant).

[0161] Case J-1: The RAR is a RAR in CBRA, or a RAR in response to a PRACH / preamble (for) CBRA, or a RAR in response to a preamble selected by the MAC layer (from the preamble for CBRA).

[0162] Case J-2: The RAR is a RAR in CFRA, or a RAR in response to a PRACH / preamble (for) CFRA, or a RAR in response to a preamble (for CFRA) indicated by a PDCCH order or RRC layer.

[0163] Case K: Scheduled / activated by DCI (format 0_0)

[0164] Case K-1: The DCI (format 0_0) has a CRC scrambled by TC-RNTI.

[0165] Case K-2: The DCI (format 0_0) has a CRC scrambled by C-RNTI / MCS-C-RNTI.

[0166] Case K-3: The DCI (format 0_0) has a CRC scrambled by CS-RNTI.

[0167] In some embodiments, in Case K-3, the PUSCH is a retransmission of the (first) (CG) PUSCH scheduled by the DCI, or an active CG PUSCH, or a scheduled CG PUSCH.

[0168] In some embodiments, the PUSCH in Case J-1 and / or Case J-2 and / or Case K-1 may be referred to as Msg3PUSCH((re-)transmission), wherein the PUSCH in Case K-1 may also be referred to as Msg3PUSCH retransmission. The DCI in Case K-1 is in CSS, and the DCI in Case K-2 and / or Case K-3 may be in USS or in CSS.

[0169] In some embodiments, only certain combinations of Case A to Case K-3 considering different aspects are supported or exist, or certain combinations of Case A to Case K-3 considering different aspects are not supported or exist.

[0170] For example, the UE does not expect some combinations of Case A to Case K-3 mentioned above to occur.

[0171] For example, for Case F, the UE does not expect Case E, or does not support Case E, that is, the UE does not expect the situation to meet both Case F and Case E at the same time.

[0172] For example, Case K-2 is not supported for Case G.

[0173] For example, for Case G and / or Case K-3, the valid / invalid symbol type needs to be considered, that is, the combination with one or more of Case H to Case I needs to be considered. For Case F and / or Case J-1 and / or Case K-2, the valid / invalid symbol type does not need to be considered, that is, the combination with Case H to Case I does not need to be considered.

[0174] The above provides illustrative examples of various cases in the embodiments of this application, but this application is not limited thereto. The various cases described above can be implemented independently, or can be combined in any way, depending on the actual application situation. Other cases can also be added.

[0175] The following explains how to determine the frequency domain resources of this PUSCH.

[0176] In some embodiments, the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol) (for transmitting the PUSCH's PRBs) are associated with at least one of the following, and / or the UE determines the frequency domain resources (allocation) of the PUSCH (for transmitting the PUSCH's PRBs) based on one or more of the following:

[0177] -Initial uplink BWP (starting PRB and / or ending PRB and / or size);

[0178] - The third frequency domain resources of the initial uplink BWP (the start PRB and / or end PRB and / or size);

[0179] -The (activated) uplink BWP (starting PRB and / or ending PRB and / or size);

[0180] - The third frequency domain resources of the (activated) uplink BWP (the start PRB and / or end PRB and / or size);

[0181] - Frequency domain offset.

[0182] In some embodiments, the third frequency domain resource of the initial uplink BWP includes the intersection of the first frequency domain resource (configured for the SCS of the initial UL BWP) and the initial uplink BWP.

[0183] In some embodiments, the third frequency domain resources of the initial uplink BWP are determined based on information used to configure the third frequency domain resources of the uplink BWP.

[0184] In some embodiments, the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol) (for transmitting the PRBs of the PUSCH (located in / corresponding to the SBFD symbol)) are associated with at least one of the above, including:

[0185] The frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol) (for transmitting the PUSCH PRBs) are determined by the FDRA field (provided RIV) in the RAR or DCI based on at least one indication, and / or, the UE determines the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol) (for transmitting the PUSCH PRBs) indicated by the FDRA field (provided RIV) in the RAR or DCI based on at least one indication.

[0186] In some embodiments, the FDRA field in a RAR (or RAR(UL) grant) can also be called the PUSCH frequency resource allocation field. The TDRA field in a RAR (or RAR(UL) grant) can also be called the PUSCH time resource allocation field. Table 2 schematically shows the contents of a RAR UL grant from the most significant bit (MSB) to the least significant bit (LSB).

[0187] Table 2

[0188] In some embodiments, the size of the FDRA field in the downlink control information (DCI) and the number of bits it includes are: For example, for Case K-1, is the size of the initial UL bandwidth part, for Case K-2 / K-3, is the size of the initial UL bandwidth part or active UL BWP.

[0189] In some embodiments, (for Case J / J-1 / J-2 / K-1,) (and / or, for Case K-2 / K-3, and the size of the (FDRA field) in the DCI is determined by the size of the activated UL BWP,) the definition of the RIV provided by the FDRA field in the RAR or DCI is as shown in Table 1 above.

[0190] In some embodiments (for Case K-2 / K-3), (when the size of the DCI (the number of bits included in the FDRA field of the DCI) is determined based on the initial UL BWP, and when the DCI is applied to a non-initial UL BWP (scheduled in the PUSCH of the initial UL BWP),) the definition of the RIV provided by the FDRA field in the RAR or DCI is shown in Table 3.

[0191] Table 3

[0192] In some embodiments, the FDRA domain / RIV indicates the frequency domain resources (located in / corresponding to the SBFD symbol) of the PUSCH based on at least one of the above, including: the length of the PRB (located in / corresponding to the SBFD symbol) indicated by the FDRA domain / RIV for the PUSCH is limited to a value associated with or determined by at least one of the above, or the maximum number of RBs allocated for the frequency domain resources (located in / corresponding to the SBFD symbol) of the PUSCH is equal to a value associated with or determined by at least one of the above.

[0193] For example, the maximum number of RBs for the frequency domain resource allocation (FDRA) for this PUSCH (located in / corresponding to the SBFD symbol) is equal to one of the following:

[0194] - The number of RBs in the initial uplink BWP (i.e., the size of the initial UL BWP);

[0195] - The number of available uplink PRBs in the initial uplink BWP;

[0196] - The number of RBs in the activated uplink BWP;

[0197] - The number of available uplink PRBs in the activated uplink BWP

[0198] - The largest of the following: the number of RBs in the initial uplink BWP and / or the number of RBs in the UL usable PRBs of the uplink BWP and / or the number of remaining RBs in the activated uplink BWP (including the number of PRBs from the first PRB of the UL usable PRBs to the last PRB of the activated UL BWP).

[0199] For example, in Table 1 It equals the maximum number of RBs for the frequency domain resource allocation (FDRA) used for this PUSCH (located in / corresponding to the SBFD symbol).

[0200] For example, in Table 1 The value of is related to the size of at least one of the terms. For example, The size of the initial UL BWP, or the size of the UL usable PRBs of the initial UL BWP, or the size of the UL usable PRBs of the activated UL BWP, or the largest / smallest value of the size of the initial UL BWP and the UL usable PRBs of the activated UL BWP, or the size from the start / first PRB of the UL usable PRBs of the activated UL BWP to the last PRB of the activated UL BWP (or the number of PRBs included).

[0201] For example, for different combinations of Case A to Case K-3 or different cases mentioned above, The definitions are different.

[0202] For example, regarding Case J / J-1( / J-2)+Case A( / B-1)(+Case C / D / E)(+Case F / G)(+Case H / H-1 / H-2 / I), This is the initial size of the UL BWP.

[0203] For example, regarding Case J / J-1( / J-2)+Case(B-1 / )B-2(+Case C / D / E)(+Case F / G)(+Case H / H-1 / H-2 / I), The size of the UL usable PRBs for the activated UL BWP.

[0204] For example, for Case K-1(+Case A / B / B-1 / B-2)(+Case C / D / E)(+Case F / G)(+Case H / H-1 / H-2 / I), This is the initial size of the UL BWP.

[0205] In some embodiments, the FDRA domain / RIV indicates the frequency domain resources of the PUSCH (located in / corresponding to the SBFD symbol) based on at least one of the above, including: the FDRA domain / RIV indicates the frequency domain resources of the PUSCH (located in / corresponding to the SBFD symbol) based on the RB number associated with at least one of the above, or the RB number allocated for the frequency domain resources of the PUSCH (located in / corresponding to the SBFD symbol) is associated with at least one of the above.

[0206] For example, (for Case J / J-1 / J-2 + Case A / B-1 (+ Case C / D / E)(+ Case H / I / E), and / or Case K / K-1 / K-2 / K-3 + Case A, and / or Case D / E) RB numbering (in ascending order of frequency domain position) starts from the first RB of the initial UL BWP (e.g., incrementing by 1 from 0 until the above). ).

[0207] For example, (for Case J / J-1 / J-2 + Case B-1 (+ Case C),) the RB numbers (in ascending order of frequency domain position) start from the RB in the active UL BWP that is the same as the first RB (frequency domain position) of the initial UL BWP (e.g., starting from 0 and incrementing by 1 until the above). ).

[0208] For example, (for Case J / J-1 / J-2 + Case A / B-1 + Case C / H-2, and / or Case K / K-1 / K-2 / K-3 + Case A, and / or Case D / E) RB numbering (in ascending order of frequency domain position) starts from the first RB of the initial UL BWP (e.g., starting from 0 and incrementing by 1 until the above). ).

[0209] For example, (for Case J / J-1 / J-2 + Case A / B / B-1 / B-2, and / or Case K / K-1 / K-2 / K-3) the RB numbering (in ascending order of frequency domain position) starts from the first RB of the active UL BWP (e.g., incrementing by 1 from 0 until the above). ).

[0210] For example, (for Case J / J-1 / J-2 + Case A + Case C, and / or Case K / K-1 / K-2 / K-3) RB numbering (in ascending order of frequency domain position) starts from the first RB of the UL usable PRB of the initial UL BWP (e.g., starting from 0 and incrementing by 1 until the above). ).

[0211] For example, RB in Table 1 start Corresponding to the RB number mentioned above. For example, RB start =0 corresponds to RB with number 0, RB start =1 corresponds to RB with number 1, and so on.

[0212] For example, the frequency domain resources of a PUSCH are indicated by the FDRA field (provided RIV) in the RAR or DCI based on the initial uplink BWP (the start PRB and / or end PRB and / or size). For example, this RIV indicates the frequency domain resources of the PUSCH (including the start RB and the number / length of RBs) based on the start RB and / or size of the initial uplink BWP. For example, assuming the values ​​in Table 1... This is the size of the initial UL BWP. Additionally, the RB numbering starts from the first PRB of this initial UL BWP.

[0213] For example, the frequency domain resources of a PUSCH are indicated by the FDRA field (provided RIV) in the RAR or DCI based on the third frequency domain resources (starting PRB and / or ending PRB and / or size) of the active uplink BWP. For example, the RIV indicates the frequency domain resources of the PUSCH based on the starting RB and / or size of the third frequency domain resources of the active uplink BWP, the number / length of the starting RB, and the RBs. For example, assuming the values ​​in Table 1... This represents the size of the third frequency domain resource. Additionally, the RB numbering starts from the first PRB of this third frequency domain resource.

[0214] For example, the frequency domain resources of a PUSCH are indicated by the FDRA field (provided RIV) in the RAR or DCI based on the initial uplink BWP (the start PRB and / or end PRB and / or size) and the third frequency domain resources (the start PRB and / or end PRB and / or size) of the active uplink BWP. For example, the RIV indicates the frequency domain resources of the PUSCH based on the start RB of the third frequency domain resources of the active uplink BWP and the size of the initial UL BWP, the number / length of the start RB, and the RBs. For example, assuming the values ​​in Table 1... This is the initial UL BWP size. Additionally, the RB numbering starts from the first PRB of this third frequency domain resource.

[0215] The following is an example of the frequency domain resources (allocation) of PUSCH (i.e., Case J / J-1 / J-2) scheduled by RAR (located in / corresponding to SBFD symbols).

[0216] In some embodiments, if the activated uplink BWP and the initial uplink BWP have the same subcarrier spacing (SCS) and the same cyclic prefix length (CP length) and the activated uplink BWP includes all resource blocks (RBs) of the initial uplink BWP (i.e., for Case B-1), or the activated uplink BWP is the initial uplink BWP (i.e., for Case A), the initial uplink BWP (its start and size) is used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol); for example, the RB numbering starts from the first RB of the initial uplink BWP (for Case A / B-1) or from the RB in the activated UL BWP that is the same as the first RB (frequency domain position) of the initial uplink BWP (for Case A / B-1), the maximum number of RBs used for frequency domain resource allocation (FDRA) is equal to the number of RBs in the initial uplink BWP.

[0217] Otherwise (i.e., for Case B-2), the active uplink BWP (start) and the initial UL BWP (size) are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). For example, the RB numbering above starts from the first RB of the active uplink BWP, and the maximum number of RBs used for frequency domain resource allocation (FDRA) is equal to the number of RBs in the initial uplink BWP (i.e., the size of the initial uplink BWP).

[0218] Figure 6 is a schematic diagram of Case A of this application, and Figure 7 is a schematic diagram of Case B-1 of this application. As shown in Figures 6 and 7, for example, addressable PRBs (e.g., the range of PRBs that can be indicated by RIV) are determined according to the initial UL BWP.

[0219] Figure 8 is a schematic diagram of Case B-2 of this application, illustrating the addressable PRBs when the SCS is the same but the CP is different. Figure 9 is another schematic diagram of Case B-2 of this application, illustrating the addressable PRBs when the SCS is the same but the activated uplink BWP does not include all resource blocks (RBs) of the initial uplink BWP. Figure 10 is another schematic diagram of Case B-2 of this application, illustrating the addressable PRBs when the SCS is different; for example, assuming the SCS of the activated uplink BWP (e.g., 30kHz) is greater than the SCS of the initial uplink BWP (e.g., 15kHz).

[0220] In some embodiments, for Case A, the initial uplink BWP (start and size) is used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). For Case B, i.e., Case B-1 / B-2, the active uplink BWP (start) and the initial UL BWP (size) are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol).

[0221] In some embodiments, for Case A and Case B, the activated uplink BWP (start) and the initial UL BWP (size) are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol).

[0222] In some embodiments, if the activated uplink BWP and the initial uplink BWP have the same subcarrier spacing (SCS) and the same cyclic prefix length (CP length) and the activated uplink BWP includes all resource blocks (RBs) of the initial uplink BWP (i.e., for Case B-1), or the activated uplink BWP is the initial uplink BWP (i.e., for Case A), the initial uplink BWP (its start and size) is used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol); for example, the RB numbering starts from the first RB of the initial uplink BWP (for Case A / Case B-1) or from the RB in the activated UL BWP that is the same as the first RB (frequency domain position) of the initial uplink BWP (for Case A / Case B-1), the maximum number of RBs used for frequency domain resource allocation (FDRA) is equal to the number of RBs in the initial uplink BWP.

[0223] Otherwise (i.e., for Case B-2), (when the size of the UL usable PRBs of the active uplink BWP is not greater than the size of the initial UL BWP), the start of the UL usable PRBs of the active uplink BWP and the size of the initial UL BWP are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). For example, the above RB numbering starts from the first RB of the UL usable PRBs of the active uplink BWP, and the maximum number of RBs used for frequency domain resource allocation (FDRA) is equal to the number of RBs of the initial uplink BWP (i.e., the size of the initial uplink BWP). Alternatively, (when the size of the UL usable PRBs of the active uplink BWP is greater than the size of the initial UL BWP), the start and / or size of the UL usable PRBs of the active uplink BWP are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). For example, the RB numbering mentioned above starts from the first RB of the UL usable PRBs of the active uplink BWP, and the maximum number of RBs used for frequency domain resource allocation (FDRA) is equal to the number of RBs of the UL usable PRBs of the active uplink BWP (i.e., the size of the UL usable PRBs of the active uplink BWP).

[0224] In some embodiments, for Case A, the initial uplink BWP (its start and size) is used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). For Case B, i.e., Case B-1 / Case B-2, (when the size of the UL usable PRBs of the activated uplink BWP is not greater than the size of the initial UL BWP), the start of the UL usable PRBs of the activated uplink BWP and the size of the initial UL BWP are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). Alternatively, (when the size of the UL usable PRBs of the activated uplink BWP is greater than the size of the initial UL BWP), the start and / or size of the UL usable PRBs of the activated uplink BWP are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol).

[0225] In some embodiments, for Case A and Case B, the UL usable PRBs (start and / or size) of the activated uplink BWP are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol).

[0226] Figure 11 is a schematic diagram of Case A of this application, and Figure 12 is a schematic diagram of Case B-1 of this application. Figure 13 is a schematic diagram of Case B-2 of this application, showing the addressable PRBs when the SCS is the same but the CP is different. Figure 14 is another schematic diagram of Case B-2 of this application, showing the addressable PRBs when the SCS is the same but the activated uplink BWP does not include all resource blocks (RBs) of the initial uplink BWP. Figure 15 is another schematic diagram of Case B-2 of this application, showing the addressable PRBs when the SCS is different; for example, assuming that the SCS of the activated uplink BWP (e.g., 30kHz) is greater than the SCS of the initial uplink BWP (e.g., 15kHz).

[0227] As shown in Figures 11 to 15, for example, addressable PRBs are determined based on the first RB of the UL usable PRBs of the activated UL BWP (i.e., non-initial UL BWP) and the number of RBs of the initial uplink BWP.

[0228] In some embodiments, addressable PRBs include the aforementioned PRBs starting from the first PRB (i.e., the PRB numbered 0). RB.

[0229] The above provides an exemplary description of the frequency domain resources (allocation) (located in / corresponding to SBFD symbols) of PUSCH (i.e., Case J / J-1 / J-2) scheduled by RAR. The following provides an exemplary description of PUSCH scheduled by DCI.

[0230] In some embodiments, the same method as described above for Case J / J-1 / J-2 is used for Case K-1. Alternatively, in other embodiments, a different method is used for Case K-1 than that described above for Case J / J-1 / J-2.

[0231] In some embodiments, for Case K-2 / K-3, the same method as described above for Case J / J-1 / J-2 is used when determining the size of the DCI / FDRA domain based on the initial UL BWP. Alternatively, in other embodiments, for Case K-2 / K-3, a different method is used when determining the size of the DCI / FDRA domain based on the initial UL BWP than described above for Case J / J-1 / J-2.

[0232] In some embodiments, for Case K-1, and / or for Case K-2 / K-3 (and when the size of the DCI / FDRA domain is determined based on the initial UL BWP), the active uplink BWP (start) and the initial UL BWP (size) are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol).

[0233] In some embodiments, for Case K-1, and / or for Case K-2 / K-3 (and when the size of the DCI / FDRA domain is determined based on the initial UL BWP), (when the size of the UL usable PRBs of the activated uplink BWP is not greater than the size of the initial UL BWP), the start of the UL usable PRBs of the activated uplink BWP and the size of the initial UL BWP are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). Alternatively, (when the size of the UL usable PRBs of the activated uplink BWP is greater than the size of the initial UL BWP), the start and / or size of the UL usable PRBs of the activated uplink BWP are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol).

[0234] In some embodiments, the frequency domain resources (allocation) of the PUSCH (corresponding to / located in the SBFD symbol) (for transmitting the PUSCH's PRBs) are associated with at least one of the following, including:

[0235] The frequency domain resources (allocation) of the PUSCH (corresponding to / located in the SBFD symbol) (PRBs for transmitting the PUSCH) are determined according to the PRBs (initial PRBs and / or number) indicated by the FDRA field (provided RIV) in the RAR or DCI and the at least one of them.

[0236] For example, the FDRA field (provided RIV) in RAR or DCI is based on at least one of the following indications for PRBs:

[0237] -Initial uplink BWP (starting RB and / or ending RB and / or size);

[0238] - The third frequency domain resources of the initial uplink BWP (the start RB and / or end RB and / or size);

[0239] -The (activated) uplink BWP (starting RB and / or ending RB and / or size);

[0240] - The third frequency domain resources of the (activated) uplink BWP (the start RB and / or end RB and / or size);

[0241] - Frequency domain offset.

[0242] For example, how the FDRA field (provided RIV) in the RAR or DCI is based on at least one of the above-mentioned indications for PRBs can be referred to the foregoing description, and this application is not limited thereto. For example, for a PUSCH scheduled by RAR, for Case A / Case B-1, the initial uplink BWP (start and size) is used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol); for Case B-2, the active uplink BWP (start) and the initial UL BWP (size) are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol). For example, for a PUSCH scheduled by DCI, for Case K-1, and / or, for Case K-2 / K-3 (and when the size of the DCI / FDRA field is determined according to the initial UL BWP), the active uplink BWP (start) and the initial UL BWP (size) are used to determine the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol).

[0243] In some embodiments, the frequency domain resources (allocation) of the PUSCH (corresponding to / located in the SBFD symbol) (PRBs for transmitting the PUSCH) are determined based on the PRBs (initial PRBs and / or number) indicated by the FDRA field (provided RIV) in the RAR or DCI and at least one of the above, including: the first / initial PRB (or the RB of the RIV) indicated by the UE according to the FDRA field (provided RIV). start The corresponding PRB and at least one of the above determine the first PRB of PUSCH.

[0244] In some embodiments, the RB offset is an offset relative to the start of the initial UL BWP (for Case J + Case A / B-1) or the start of the activated UL BWP (for Case J + Case B / B-1 / B-2). For example, this offset is the offset between the start and the first / starting PRB indicated by the RIV.

[0245] In some examples, an implicit RB offset can be used. For example, the PRBs of the PUSCH (corresponding to / located in the SBFD symbol) can be determined based on the PRBs indicated by the RIV and the size of the initial UL BWP and / or the start and / or size of the UL usable PRBs. The determined PRBs of the PUSCH (corresponding to / located in the SBFD symbol) (the starting PRB) may have an RB offset from the PRBs indicated by the RIV (the starting PRB).

[0246] For example, the starting PRB index of the PUSCH (in the SBFD symbol, or located at / corresponding to the SBFD symbol) references the starting RB of the active uplink BWP, and the starting PRB of the PUSCH is determined based on at least one of the following:

[0247] (For example, for Case C / H-1, but not limited to this)

[0248] in, It is the starting PRB index of the UL BWP start (RB) reference active (in the SBFD symbol, or located at / corresponding to the SBFD symbol) (e.g., This is the starting PRB index of PUSCH in the SBFD symbol with reference to the start of the UL BWP; for example, the PRBs in the active UL BWP (in ascending order of frequency domain position) are numbered / indexed starting from the first RB (e.g., incrementing by 1 from 0). It equals the number / index of the starting PRB of this PUSCH.

[0249] This is the starting PRB index of the reference active UL BWP start (RB) indicated by the FDRA field (provided RIV) of the RAR or DCI, or the index of the reference active UL BWP start (RB) corresponding to the first / starting PRB indicated by the FDRA field (provided RIV) of the RAR or DCI. For example, PRBs in the active UL BWP (in ascending order of frequency domain position) are numbered / indexed starting from the first RB (e.g., incrementing by 1 from 0). This is equal to the number / index corresponding to the starting PRB indicated by the FDRA field (provided RIV) of the RAR or DCI. Specifically, the starting PRB index of the reference active UL BWP start (RB) is the same as the aforementioned RIV-based RB number, or the starting PRB index of the reference active UL BWP start (RB) is different from the aforementioned RIV-based RB number. For example, when the aforementioned RIV-based RB number starts from the start of the active UL BWP, they are the same. For example, for Case B, when the aforementioned RIV-based RB number starts from the start of the initial UL BWP, and the start of the initial UL BWP is different from the start of the active UL BWP, they are different.

[0250] It is the reference index of the starting PRB of the active UL BWP (either the active UL BWP or the initial UL BWP).

[0251] It is the number of PRBs in the activated UL BWP or the initial UL BWP;

[0252] It is the number of PRBs (for activated UL BWP or initial UL BWP) of UL usable PRBs;

[0253] It is the number of PRBs in the PUSCH (the size of the PUSCH).

[0254] For example, the starting PRB index of the PUSCH (in the SBFD symbol, or located in / corresponding to the SBFD symbol) refers to the start of the UL usable PRBs of the active UL BWP, and the starting PRB of the PUSCH in the first time-domain resource (SBFD symbol) is determined based on at least one of the following:

[0255] in, It is the starting PRB index of the UL usable PRBs of the active UL BWP (in the SBFD symbol, or located at / corresponding to the SBFD symbol); for example, the PRBs in the active UL BWP's UL usable PRBs (in ascending order of frequency domain position) are numbered / indexed starting from the first RB (e.g., incrementing by 1 from 0). It equals the number / index of the starting PRB of this PUSCH.

[0256] In some embodiments, (when frequency hopping (FH) is enabled, the UE needs to The corresponding PRB references the starting PRB index of the UL BWP.

[0257] In other examples, explicit RB offsets can be used, such as those that are predefined or indicated by higher-layer signaling and / or physical-layer signaling.

[0258] In some embodiments, SIB1 includes information indicating one or more RB offsets. When multiple RB offsets are indicated, the RAR or DCI includes information indicating one of the RB offsets, and the RB offset indicated by the RAR / DCI is applied to the scheduled / activated PUSCH. For example, the starting PRB index of the PUSCH references the start position of the uplink BWP, and the starting PRB of the PUSCH in the first time-domain resource (SBFD symbol) is determined based on at least one of the following:

[0259] in, It is the starting PRB index of the UL BWP start (RB) of the PUSCH (in the SBFD symbol, or located in / corresponding to the SBFD symbol) reference active; The RB offset is a predefined or indicated value, which may be a positive integer, a negative integer, or zero.

[0260] For example, the starting PRB index of the PUSCH refers to the starting position of the UL usable PRB, and the starting PRB of the PUSCH in the first time-domain resource (SBFD symbol) is determined based on at least one of the following:

[0261] in, It is the starting PRB index of the UL usable PRBs of the PUSCH (in the SBFD symbol, or in / corresponding to the SBFD symbol) reference active UL BWP.

[0262] In some embodiments, when frequency hopping (FH) is enabled, the UE can also refer to the start of the UL BWP to determine the corresponding starting PRB index for the PUSCH.

[0263] In some embodiments, the frequency domain resources (allocation) of the PUSCH (corresponding to / located in the SBFD symbol) (PRBs for transmitting the PUSCH) are associated with at least one of the following: the UE processes the FDRA field in the RAR or DCI according to one or more of the following, the processing including truncation and / or insertion of bits.

[0264] For example, truncate bits in the FDRA field of the RAR and / or insert bits in the FDRA field based on the size of the initial UL BWP and / or the size of the UL usable PRBs of the activated UL BWP.

[0265] For example, for Case J / J-1 / J-2+Case A, truncate and / or insert bits according to the size of the initial UL BWP.

[0266] For example, for Case J / J-1 / J-2+Case B / B-1 / B-2(+Case C / H-2), for (when the size of the UL usable PRBs of the activated UL BWP is not greater than the size of the initial UL BWP), bits are truncated and / or inserted according to the size of the initial UL BWP, or (when the size of the UL usable PRBs of the activated UL BWP is greater than the size of the initial UL BWP), bits are truncated and / or inserted according to the size of the UL usable PRBs of the activated UL BWP.

[0267] In some embodiments, the UE determines the bits it provides / includes for indicating frequency hopping offset and / or RIV and / or (RIV) indication PRBs based on the FDRA field after truncation or expansion (i.e., the inserted bits).

[0268] Taking RAR as an example. For instance, Table 4 schematically illustrates a portion of the processing of the Frequency Domain Resource Allocation (FRDA) domain based on the initial UL BWP size. Processing is based on the size of the UL usable PRBs of the activated UL BWP, for example, in Table 4... For example, the size of the UL usable PRBs representing the active UL BWP.

[0269] Table 4

[0270] In some embodiments, the UE does not expect the PRBs of the PUSCH in the SBFD symbol to overlap with the PRBs other than the UL usable PRBs of the activated UL BWP.

[0271] In some embodiments, the frequency domain resources (allocation) of the PUSCH (located in / corresponding to the SBFD symbol) (for transmitting the PRBs of the PUSCH (located in / corresponding to the SBFD symbol)) are associated with the at least one, including: the parameter K for determining the resource indication value RIV indicating / corresponding to the PRBs is associated with the at least one.

[0272] For example, (for Case K-2 / K-3), the parameter K (refer to Table 3) is determined as follows:

[0273] if K is a set {1, 2, 4, 8} that satisfies The maximum value, otherwise K = 1;

[0274] Or, if K is a set {1, 2, 4, 8} that satisfies The maximum value, otherwise K = 1;

[0275] Or, if K is a set {1, 2, 4, 8} that satisfies The maximum value, otherwise K = 1;

[0276] in, The number of RBs that activate the uplink BWP. The number of RBs in the initial uplink BWP. This represents the number of RBs available for uplink PRBs.

[0277] The following is a schematic explanation of frequency hopping (FH).

[0278] In some embodiments, the RAR or DCI includes a frequency hopping flag field.

[0279] For example, the frequency hopping flag includes 1 bit. If the value of the frequency hopping flag is 0, then PUSCH does not hop; otherwise, if the value of the frequency hopping flag is 1, then PUSCH hops.

[0280] The following description uses the example of PUSCH being used for uplink grant (ULgrant) scheduling in the random access response (RAR) (Case J), ​​or PUSCH being scheduled by downlink control information (CRC scrambled by TC-RNTI) (Case K-1); this application is not limited to these examples.

[0281] In some embodiments (for Case C / E / H-2 / I), (when the PUSCH has frequency hopping), the number of bits included in the RAR or DCI (in the FDRA field) for indicating the frequency hopping offset and / or the frequency hopping offset indicated by the RAR or DCI (in the FDRA field) and / or the starting frequency domain resources of the PUSCH (corresponding to / located in the SBFD symbol) for the (corresponding) second hop are related to at least one of the following:

[0282] -Initial uplink BWP (starting RB and / or ending RB and / or size);

[0283] - The third frequency domain resources of the initial uplink BWP (the start RB and / or end RB and / or size);

[0284] -The (activated) uplink BWP (starting RB and / or ending RB and / or size);

[0285] - The third frequency domain resources of the (activated) uplink BWP (the start RB and / or end RB and / or size);

[0286] - Frequency offset.

[0287] For example, Table 5 schematically shows the number of frequency hopping bits (N) UL,hop (Example based on the initial uplink BWP being determined.)

[0288] Table 5

[0289] In some embodiments, (for Case D / E / I), the frequency offset of the PUSCH (corresponding to / located in the SBFD symbol), i.e., the frequency hopping offset, is determined based on the size of the initial uplink BWP, or, for non-SBFD symbols, the frequency hopping offset is determined based on the size of the initial uplink BWP. For example, in the last column of Table 5... This indicates the initial size of the UL BWP.

[0290] In some embodiments (for Case C / E / I), the frequency offset of the PUSCH (corresponding to / located in the SBFD symbol) is determined based on the size of the UL usable PRBs (of the initial uplink BWP or the active UL BWP), or the frequency offset for the SBFD symbol is determined based on the size of the UL usable PRBs (of the initial uplink BWP or the active UL BWP), for example, in the last column of Table 5. This indicates the size of UL usable PRBs (for the initial uplink BWP or the active UL BWP).

[0291] In some embodiments, the PUSCH in the first time domain resource (SBFD symbol) determines the number of bits for frequency hopping and / or the corresponding frequency offset based on the size of UL usable PRBs in the (activated) uplink BWP, or the number of bits for frequency hopping and / or the corresponding frequency offset is determined based on the size of UL usable PRBs in the initial uplink BWP.

[0292] In some examples, such as Table 6, the corresponding frequency offset of the second hop is determined based on the size of the initial UL BWP for the PUSCH in the non-SBFD symbol.

[0293] Table 6

[0294] For example, for PUSCH in the SBFD symbol, the second hop (2) is determined based on the size (range) of the UL usable PRBs of the (activated) uplink BWP. nd The corresponding frequency offset of the hop; for example, for PUSCH in the SBFD symbol, the second hop (2 hops) is determined based on the size (range) of the UL usable PRBs of the initial uplink BWP. nd The corresponding frequency shift of (hop).

[0295] For example, based on the size of the UL usable PRBs of the (activated) uplink BWP, (e.g. and The UE determines the number of valid / effective frequency hopping bits (N). UL,hop Or the number of truncated frequency hopping bits (N) UL,hop ), and / or, (e.g. and UE pad bits to frequency hopping bits (N) UL,hop ).

[0296] For example, based on the size of the UL usable PRBs of the initial uplink BWP, (e.g.) and The UE determines the number of valid / effective frequency hopping bits (N). UL,hop Or the number of truncated frequency hopping bits (N) UL,hop ), and / or, (e.g. and UE pad bits to frequency hopping bits (N) UL,hop ).

[0297] Tables 7, 8, and 9 show some examples, assuming that the number of PRBs in the ULusable PRBs of the activated UL BWP may be greater than that of the initial UL BWP, for example when the activated UL BWP is used for Case B.

[0298] Table 7

[0299] Table 8

[0300] Table 9

[0301] Table 10 shows another example, assuming that the number of PRBs in the UL usable PRBs of the (activated) UL BWP is no greater than that of the initial UL BWP. For example, the UE does not expect the number of RBs in the UL usable PRBs of the (activated) UL BWP to be greater than the number of RBs in the initial UL BWP.

[0302] Table 10

[0303] Table 11 shows another example, illustrating the determination of frequency offset based on the determined frequency hopping bits (with / without padding bits).

[0304] Table 11

[0305] The above examples illustrate the case where the UE processes the frequency hopping bits to determine the frequency hopping offset, but this application is not limited to this.

[0306] Table 12 shows another example, illustrating a situation where the frequency hopping offset can be determined directly.

[0307] Table 12

[0308] Table 13 shows another example, for instance when and The UE does not expect the frequency hopping bit to be "10" and / or "11".

[0309] Table 13

[0310] In some examples, such as Table 14, the number of bits for frequency hopping and the corresponding frequency offset for the second hop are determined based on the size of the initial UL BWP for the PUSCH in a non-SBFD symbol.

[0311] Table 14

[0312] For example, for PUSCH in an SBFD symbol, the number of hopping bits (N) is determined based on the size (range) of the UL usable PRBs of the (activated) uplink BWP. UL,hop ) and the second jump (2 nd The corresponding frequency offset of the hop; for example, for the PUSCH in the SBFD symbol, the number of hop bits (N) is determined according to the size (range) of the UL usable PRBs of the initial uplink BWP. UL,hop ) and the second jump (2nd The corresponding frequency shift of the second hop (2 hops) nd The corresponding frequency offset of (hop) can be simply referred to as frequency hopping offset.

[0313] Table 15 shows another example.

[0314] Table 15

[0315] The following is a further explanation of the initial RB.

[0316] For example, the following RB ULSBstart It can also be replaced with the aforementioned

[0317] For example, the following RB start For example, the starting PRB index of the PUSCH located at / corresponding SBFD symbol (referencing the start of the active UL BWP) determined by the aforementioned method.

[0318] For example, the following RB offset It refers to the frequency hopping offset for the SBFD symbol, or the frequency hopping offset for the corresponding SBFD symbol of the PUSCH.

[0319] In some examples (for J / K-1+F), for intra-slot frequency hopping in the PUSCH time slot of an SBFD symbol, the starting RB in each hop can be given by the following formula:

[0320] or,

[0321] In some examples (for J / K-1+G), for inter-slot frequency hopping of PUSCH in SBFD symbols, when pusch-DMRS-Bundling is not enabled, the slot... The initial RB during the period is given by the following formula:

[0322] or,

[0323] The frequency domain resources have been illustrated above; the time domain resources will now be discussed. The following explanation uses the cases where the PUSCH is used for uplink grant scheduling in the Random Access Response (RAR), and / or where the PUSCH is scheduled by downlink control information (e.g., DCI format 0_0 with CRC scrambled by TC-RNTI). PUSCH repetition is possible, such as PUSCH repetition in Msg 3 transmission (which can be referred to as Msg.3repepition).

[0324] In some embodiments, only Case H / H-1 / H-2 is supported for Case J / J-1 / J-2 / K-1+Case G.

[0325] In some embodiments, for Case H, the UE determines the time slot based on the RAR and / or DCI and / or reference repetition (e.g., the first repetition) and / or reference time slot (e.g., the time slot determined by the time slot offset k2 indicated by the RAR / DCI, such as slot n+k2+Δ+2). μ ·K Cell,offset ,whereΔis a pre-defined / indicated value,eg0,1,2,K cell,offset is provided by cellSpecificKoffset; otherwise, if not provided, K cell,offset The symbol assigned in (=0) determines whether to apply Case H-1 or Case H-2 for PUSCH of RAR / DCI scheduling.

[0326] For example, for PUSCH with repetition, if the reference repetition or the symbol allocated in the reference slot (or, symbol allocation) overlaps with the non-SBFD symbol, it is Case H-1; if the reference repetition or the symbol allocated in the reference slot overlaps with the SBFD symbol, it is Case H-2.

[0327] For example, for PUSCH with repetition, if the symbol allocated in the reference repetition or reference slot (or symbol allocation) overlaps with the non-SBFD symbol, it is Case H-1; if the symbol allocated in the reference repetition or reference slot (or symbol allocation) overlaps with the SBFD symbol, it is Case H-2.

[0328] In some embodiments, (when the PUSCH has repetitions) (when the PUSCH is associated with a PRACH using a second RO) the UE determines the time slot in which the PUSCH repetitions based on a first time domain resource and / or a second time domain resource.

[0329] For example, for a PUSCH transmission associated with a PRACH transmission using additional RO, the time slot in which the PUSCH repetition occurs can be determined based on the SBFD symbol and / or non-SBFD symbol.

[0330] Table 16 is an example of how to determine the slots (N·K slots) where PUSCH repeats.

[0331] Table 16

[0332] Table 17 provides another example of how to determine the slots (N·K slots) where PUSCH repeats. Case J is used as an example; a similar method can be applied to Case K-1.

[0333] Table 17

[0334] Table 18 provides another example of how to determine the slots (N·K slots) where PUSCH repeats. Case J is used as an example; a similar method can be applied to Case K-1.

This can improve uplink transmission capacity and coverage, reduce uplink transmission latency, and increase resource allocation flexibility and resource utilization.
