BRIEF DESCRIPTION OF THE DRAWINGS

[0090] The above and other aspects and their implementation manners are described in more detail in the accompanying drawings, the description of the specification and the claims.

[0093] Figure 3 An example of a schematic diagram of a wireless network node according to an embodiment of the present disclosure is shown;

[0094] Figure 4 Figure D shows a timing diagram related to downlink control information and a physical uplink control channel according to an embodiment of the present disclosure;

[0095] Figure 5 A flowchart of a process according to an embodiment of the present disclosure is shown;

[0096] Figure 6 A flowchart of a process according to an embodiment of the present disclosure is shown. Detailed implementation manners

[0097] In Long-Term Evolution (LTE) and New Radio (NR), Discontinuous Reception (DRX) can be used for power saving of a terminal (or User Equipment (UE)).

[0098] The basic mechanism of DRX is to configure a DRX cycle for the UE, and the drx-ondurationTimer starts from a DRX cycle. During the drx-ondurationTimer, the UE is in the 'DRX On' state and continuously monitors the Physical Downlink Control Channel (PDCCH). If the UE successfully decodes the PDCCH, the UE remains awake (in the 'DRX On' state) and starts an inactivity timer. After the drx-ondurationTimer or the drx activityTimer expires, the UE can enter the sleep state (in the 'DRX off' state). In the 'DRX off' state, the UE does not monitor the PDCCH to save power.

[0099] In NR, more energy-saving technologies are proposed. For example, Downlink Control Information (DCI) format 2_6 is used to notify one or more UEs of energy-saving information (e.g., wake-up indication) outside the DRX activation time; the fields of DCI formats 0_1 and 1_1 can be used to indicate the minimum applicable scheduling offset (cross-slot scheduling), and DCI format 0_1 or 1_1 or 2_6 can be used to indicate the dormancy of a Secondary Cell (SCell), etc.

[0100] However, the UE still needs to follow the Physical Downlink Shared Channel (PDSCH) processing time N1 and / or the Physical Uplink Shared Channel (PUSCH) preparation process time N2 to process data, and the energy-saving gain is limited.

[0101] Reference Figure 1A -C describes the existing processing time in more detail. Figure 1A The figure shows the PDSCH processing time N1. Figure 1B The figure shows the PUSCH preparation process time N2. Figure 1C The figure shows the Medium Access Control (MAC) Control Element (CE) processing time. In addition, the CSI calculation time and the PDCCH decoding time are briefly described below.

[0102] The PDSCH processing time N1 is related to the number of symbols of the PDSCH processed by the UE. Specifically, the PDSCH processing time N1 is a parameter used to calculate the minimum time gap between the end position of the last symbol of the PDSCH carrying the confirmed transport block (TB) and the first uplink symbol of the Physical Uplink Control Channel (PUCCH) carrying Hybrid Automatic Repeat Request Acknowledgement (HARQ-ACK) information.

[0103] Table 1 shows the first UE processing time of the PDSCH and the third UE processing time of the PDSCH.

[0104] Table 1:

[0105]

[0106] In Table 1, if the PDSCH DM-RS position l of the additional DM-RS is l=12, then N 1,0 =14; otherwise N 1.0 =13.

[0107] The PUSCH preparation process time N2 is the number of symbols. Specifically, the PUSCH preparation process time N2 is used to calculate the minimum time interval between the end position of the last symbol of the PDCCH carrying the downlink control information (DCI) for scheduling the PUSCH and the first uplink symbol in the PUSCH.

[0108] Table 2 shows the first UE processing time of the PUSCH preparation time and the third UE processing time of the PUSCH preparation time.

[0109] Table 2:

[0110]

[0111] MAC CE processing time ( Figure 1C The application time in (i) is related to the time between the PUCCH with the HARQ-ACK information and the time slot in which the command carried by the PDSCH is applied.

[0112] The CSI calculation time is related to multiple symbols. It is used to calculate the minimum time gap between the last symbol end position of the PDCCH that triggers the CSI report and the uplink symbol of the CSI report. It is also used to calculate the latest non-periodic channel state information reference signal (CSI-RS) resources for channel measurement, non-periodic CSI-interference measurement (IM) for interference measurement, and non-periodic non-zero power (NZP) CSI-RS for interference measurement. The minimum time gap between the last symbol end position in time and the first uplink symbol of the nth CSI report.

[0113] Table 3 shows the first UE processing time for CSI calculation delay requirements 1 and 2.

[0114] Table 3:

[0115]

[0116]

[0117] In Table 3, X0, X1, X2, and / or X3 are determined according to the beamReportTiming of the UE-reported capabilities. Additionally, KB l is also determined according to the beamReportTiming of the UE-reported capabilities.

[0118] The PDCCH decoding time is related to the time taken by the UE to decode the PDCCH / DCI and is expressed in terms of the number of symbols / slots.

The communication unit 320 may be a transceiver and is used to send and receive signals (e.g., messages or data packets) according to the processing result of the processor 300. In one example, the communication unit 320 sends and receives signals via Figure 3 at least one antenna 322 shown.

[0124] In one embodiment, the storage unit 310 and the program code 312 may be omitted. The processor 300 may include a storage unit storing program code.

[0125] The processor 300 may implement any steps described in the exemplary embodiments on the wireless network node 30, for example, by executing the program code 312.

[0126] The communication unit 320 may be a transceiver. Alternatively or additionally, the communication unit 320 may combine a sending unit and a receiving unit, and the sending unit and the receiving unit are respectively configured to send signals to a wireless terminal (e.g., a user equipment) and receive signals from the wireless terminal.

[0127] Generally, in one embodiment, a more relaxed UE processing time is provided, where the UE can use the relaxed UE processing time to save energy.

[0128] The following description relates to the user equipment side or the gNB side.

[0129] Specifically, a method related to applying the UE processing time based on a first condition is provided.

[0130] In some embodiments, the process related to applying or using the UE processing time may include determining the UE processing time and at least one of, for example, performing / applying the UE processing time to a scheduled transmission.

[0131] In some embodiments, the UE processing time includes a first UE processing time, a second UE processing time, and a third UE processing time.

[0132] In some embodiments, the UE performs based on the second UE processing time, and the processor that allows the clock frequency to be reduced can be slower, or the hardware processing for calculation and energy saving can be reduced.

[0133] In some embodiments, each UE processing time includes at least one of the following: Physical Downlink Shared Channel (PDSCH) processing time N1, Physical Uplink Shared Channel (PUSCH) preparation process time N2, Medium Access Control (MAC) Control Element (CE) processing time, Channel State Information (CSI) calculation time, or Physical Downlink Control Channel (PDCCH) decoding time.

[0134] Specifically, according to one embodiment, in addition to the above first and third UE processing times, a second UE processing time is provided. The second UE processing time allows a more relaxed time than the first UE processing time. The third UE processing time only includes N1 and N2.

[0135] In some embodiments, the second UE processing time is greater than or equal to at least one of the first UE processing time or the third UE processing time.

[0136] In some embodiments, the second UE processing time is greater than or equal to the first UE processing time and less than 10 times the first UE processing time. For example, the second UE processing time can be greater than or equal to 1.5 times the first UE processing time.

[0137] In some embodiments, the processing time of the second UE is greater than or equal to 2 times the processing time of the third UE and less than 20 times the processing time of the third UE. For example, the processing time of the second UE may be greater than or equal to 3 times the processing time of the third UE.

[0138] In some embodiments, the execution / application of the UE processing time may indicate that the UE does not expect to receive a PDSCH scheduling indication that does not follow N1 in the UE processing time. In some embodiments, the execution / application of the UE processing time means that the UE does not expect to receive a PUSCH scheduling indication that does not follow N2 in the UE processing time. In some embodiments, the execution / application of the UE processing time means that the UE does not expect to process a CSI report that does not follow the CSI calculation time in the UE processing time. In some embodiments, the execution / application of the UE processing time means that the UE does not expect to apply the indication carried by the PDSCH until the time between the PUCCH with HARQ-ACK information and the slot applying the command carried by the PDSCH satisfies the MAC CE processing time in the processing time. In some embodiments, the execution / application of the UE processing time means that the UE does not expect to complete decoding the DCI or apply the indication carried by the DCI until the PDCCH decoding time in the UE processing time is satisfied.

[0139] In some embodiments, if one of the times in the UE processing time (e.g., N1, N2, MAC CE processing time, CSI calculation time, and PDCCH decoding time) is applied, then one or more of the remaining times in the corresponding UE processing time may also be applied. For example, if N1 in the processing time of the second UE is applied, then the PDCCH decoding time in the processing time of the second UE may also be applied.

[0140] Next, the definition of the processing time of the second UE is given.

[0141] In some embodiments, the characteristics of the processing time of the second UE include at least one of the following: the PDSCH processing time N1 in the processing time of the second UE is greater than or equal to the PDSCH processing time N1 in the processing time of the first UE; the PUSCH preparation process time N2 in the processing time of the second UE is greater than or equal to the PUSCH preparation process time N2 in the processing time of the first UE; the MAC CE processing time in the processing time of the second UE is greater than or equal to the MAC CE processing time in the processing time of the first UE; the CSI calculation time in the processing time of the second UE is greater than or equal to the CSI calculation time in the processing time of the first UE; or the PDCCH decoding time in the processing time of the second UE is greater than or equal to the PDCCH decoding time in the processing time of the first UE.

[0142] In some embodiments, the PDSCH processing time N1 in the second UE processing time is associated with at least one of the following: PDSCH dedicated demodulation reference signal (DMRS), subcarrier spacing (SCS), PDSCH mapping type, frequency range (FR) type, higher layer signaling, the PDSCH processing time in the first UE processing time, UE capabilities, UE type (or UE category), or a scaling factor.

[0143] In the present disclosure, UE capabilities may be equal to the UE type or UE category.

[0144] In some embodiments, the value of the PDSCH processing time in the second UE processing time is associated with at least the UE capabilities.

[0145] In some embodiments, N1 in the second UE processing time has more than one value. For example, if the UE reports support for the first UE capabilities, the first value of N1 in the second UE processing time is applied. If the UE reports support for the second UE capabilities, the second value of N1 in the second UE processing time is applied.

[0146] In some embodiments, the first or second UE capabilities may include the supported maximum latency, maximum data rate, maximum modulation order, or use case. Among the first and second UE capabilities, the maximum latency, maximum data rate, maximum modulation order, or use case are different.

[0147] As another example, if the UE reports support for the first UE capabilities, the first value of N1 in the second UE processing time is applied. If the UE reports support for the second UE capabilities, the second value of N1 in the second UE processing time is applied. If the UE reports support for the third UE capabilities, N1 in the first UE processing time is applied.

[0148] In some embodiments, the first, second, or third UE capabilities may include the supported maximum latency, maximum data rate, maximum modulation order, or use case. Among the first, second, and third UE capabilities, the maximum latency, maximum data rate, maximum modulation order, or use case are different.

[0149] In some embodiments, if the UE reports support for the first or second UE capabilities, N1 in the second UE processing time will be applied. If the UE reports support for the third UE capabilities, N1 in the first UE processing time will be applied.

[0150] In some embodiments, the maximum latency in the first capability is greater than the maximum latency in the second capability. In some embodiments, the maximum latency in the second capability is greater than the maximum latency in the third capability.

[0151] In some embodiments, the maximum data rate or the maximum modulation order in the first capability is less than the maximum data rate or the maximum modulation order in the second capability. In some embodiments, the maximum data rate or the maximum modulation order in the second capability is less than the maximum data rate or the maximum modulation order in the third capability.

[0152] In some embodiments, the use cases in the first or second capabilities are associated with use cases of reduced capabilities (e.g., industrial wireless sensors, video surveillance, and wearable devices).

[0153] In some embodiments, the value of the PDSCH processing time in the second UE processing time is at least associated with the UE type. For example, if the UE is the first type of UE, the second UE processing time is applied; otherwise, the first or third UE processing time is applied.

[0154] In some embodiments, the first type of UE is a UE with reduced capabilities (e.g., industrial wireless sensors, video surveillance, or wearable devices), a UE that supports reduced capabilities, an NR light UE, a UE with limited bandwidth, or a coverage-enhanced UE.

[0155] In some embodiments, the PDSCH processing time N1 is at least associated with the SCS (as shown in Table 4 below).

[0156] Table 4:

[0157] μ PDSCH processing time N1 (symbols) 0 Value 1 1 Value 2 2 Value 3 3 Value 4

[0158] In Table 4, μ is the numerology, where μ = 0 means SCS = 15 kHz; μ = 1 means SCS = 30 kHz; μ = 2 means SCS = 60 kHz; μ = 3 means SCS = 120 kHz.

[0159] In some embodiments, a larger SCS is associated with a larger N1. That is, SCS and N1 are positively correlated.

[0160] In some embodiments, each N1 candidate value is a multiple of X, where X is greater than 0. For example, X = 1.5 or 4. In one example, value 1 = 20, value 2 = 24, value 3 = 32, value 4 = 36.

[0161] In some embodiments, N1 corresponding to the first SCS is greater than or equal to 1.1 times of N1 corresponding to the second SCS and less than 10 times of N1 corresponding to the second SCS, where the first SCS is greater than the second SCS. For example, N1 corresponding to the first SCS may be greater than or equal to 1.25 times of N1 corresponding to the second SCS.

[0162] In some embodiments, the PDSCH processing time N1 is associated with at least one PDSCH DRMS, where the PDSCH DRMS includes at least one of the following: higher layer configuration and DMRS position.

[0163] In some embodiments, for dmrs-AdditionalPosition = pos0 and dmrs-AdditionalPosition ≠ pos0, N1 has different values (as shown in Table 5 below).

[0164] Table 5:

[0165]

[0166] Each N1 value for dmrs-AdditionalPosition ≠ pos0 is greater than the N1 value for dmrs-AdditionalPosition = pos0 associated with the same parameter set (this is because dmrs-AdditionalPosition ≠ pos0 means that the PDSCH has more than one DMRS position in a time slot and may take the UE more time to decode the PDSCH).

[0167] In some embodiments, the N1 value (Value_type 2) for dmrs-AdditionalPosition ≠ pos0 is associated with the N1 value (Value_type 1) for dmrs-AdditionalPosition = pos0 associated with the same parameter set. For example, Value_type2 = Value_type1 + d, where d is greater than 0, for example, d = 3, 4, or 5.

[0168] In some embodiments, the N1 value for dmrs-AdditionalPosition = pos0 in the second UE processing time (A1) is associated with the N1 value for dmrs-AddtionalPosition ≠ pos0 in the first UE processing time (A2). In one example, A1 = A2. In another example, A1 = A2 + t, where t is greater than 0 and less than 50.

[0169] In some embodiments, for different dmrs-AdditionalPosition configurations, the N1 value may be different (as shown in Table 6 below).

[0170] Table 6:

[0171]

[0172]

[0173] In some embodiments, for the same parameter set, the N1 value of dmrs-AdditionalPosition = pos3 is not less than the N1 value of the unconfigured dmrs AddtionalPosition, the N1 value of the unconfigured dmrs-AdditionalPosition is not less than the N1 value of dmrs-AddationalPosition = pos1, and the N1 value of dmrs-AddtionalPosition = pos1 is not less than the N1 value of dmrs-Additional Position = pos0.

[0174] In some embodiments, the N1 value of dmrs-AdditionalPosition ≠ pos0 is associated with dmrs-AdditionalPosition = pos0 (value_1). For example, the N1 value of dmrs-AdditionalPosition = pos1 is equal to value_1 + d, the N1 value of dmrs-additionalPosation = pos3 is equal to value_1 + X2 * d, and the N1 value of the unconfigured dmrs-AddtionalPosition is equal to value_1 + X1 * d. X1, X2, and d are greater than 0. In some embodiments, X1 ≤ X2.

[0175] In some embodiments, the N1 value in the second UE processing time is associated with at least one of the N1 value in the first UE processing time and the scaling factor.

[0176] For example, each N1 value in the second UE processing time is equal to the N1 value in the first UE processing time with the same dmrs-AdditionalPosition and the same SCS configuration plus d1, where d1 is greater than 0.

[0177] In another example, each N1 value in the second UE processing time with dmrs-AdditionalPosition = pos0 in dmrs-DownlinkConfig in both dmrs-DownlinkForPDSCH MappingTypeA and dmrs DownlinkForPDCCH Mapping TypeB is equal to the N1 value in the first UE processing time with the same dmrs-AdditionalPosition and the same SCS configuration plus d2, where d2 is greater than 0. Each N1 value in the second UE processing time with dmrs-AdditionalPosition ≠ pos0 in DMRS-DownlinkConfig in both dmrs-DownlinkForPDSCH-mapping typeA and dmrs-DownlinkForPDSCH-mapping typeB is equal to the N1 value in the first UE processing time with the same dmrs-AdditionalPosition and the same SCS configuration plus d3, where d3 is greater than 0.

[0178] In another example, each N1 value in the second UE processing time with dmrs-AdditionalPosition = pos0 in DMRS-DownlinkConfig in both dmrs-DownlinkForPDSCH-MappingTypeA and dmrs-DownlinkForPDSCH-MappingTypeB is equal to the N1 value in the first UE processing time with the same dmrs-AdditionalPosition and the same SCS configuration multiplied by d2, where d2 is greater than 0. Each N1 value in the second UE processing time with dmrs-AdditionalPosition ≠ pos0 in DMRS-DownlinkConfig in both dmrs-DownlinkForPDSCH-MappingTypeA and dmrs-DownlinkForPDSCH-MappingTypeB is equal to the N1 value in the first UE processing time with the same dmrs-AdditionalPosition and the same SCS configuration multiplied by d3, where d3 is greater than 0.

[0179] In some embodiments, d2 = d3.

[0180] In some embodiments, d1, d2, or d3 is at least associated with SCS, UE capabilities, or UE type (or UE category).

[0181] In some embodiments, the PDSCH processing time N1 in the second UE processing time is configured by higher layer signaling.

[0182] In some embodiments, for different PDSCH mapping types, N1 in the second UE processing time is different. For example, N1 in the second UE processing time associated with PDSCH mapping type A is greater than N1 in the second UE processing time associated with PDSCH mapping type B.

[0183] In some embodiments, N1 in the second UE processing time is determined based at least on the FR type. For example, N1 in the second UE processing time associated with FR 2 is greater than N1 in the second UE processing time associated with FR 1.

[0184] Next, the PUSCH preparation process time N2 in the second UE processing time is described according to various embodiments.

[0185] In some embodiments, the PUSCH preparation process time N2 in the second UE processing time is associated with at least one of the following: SCS, the PUSCH preparation process time N2 in the first UE processing time, UE capability, UE type (or UE category), higher layer signaling, and FR type.

[0186] In some embodiments, the value of the PUSCH preparation process time N2 in the second UE processing time is associated with UE capability.

[0187] In some embodiments, the second UE processing time can have more than one value. For example, if the UE reports support for the first UE capability, the first value of the second UE processing time is applied. If the UE reports support for the second UE capability, the second value of the second UE processing time is applied. The first or second UE capability can include the supported maximum latency, maximum data rate, maximum modulation order, or use case. Among the first and second UE capabilities, the maximum latency, maximum data rate, maximum modulation order, or use case can be different.

[0188] In another example, if the UE reports support for the first UE capability, the first value of the second UE processing time is applied. If the UE reports support for the second UE capability, the second value of the second UE processing time is applied. If the UE reports support for the third UE capability, the first UE processing time is applied. The first, second, or third UE capability can include the supported maximum latency, maximum data rate, maximum modulation order, or use case. Among the first, second, and third UE capabilities, the maximum latency, maximum data rate, maximum modulation order, or use case are different.

[0189] In some embodiments, if the UE reports support for the first or second UE capability, the second UE processing time will be applied. If the UE reports support for the third UE capability, the first UE processing time will be applied.

[0190] In some embodiments, the maximum latency in the first capability is greater than the maximum latency in the second capability. In some embodiments, the maximum latency in the second capability is greater than the maximum latency in the third capability.

[0191] In some embodiments, the maximum data rate or maximum modulation order in the first capability is less than the maximum data rate or maximum modulation order in the second capability. In some embodiments, the maximum data rate or maximum modulation order in the second capability is less than the maximum data rate or maximum modulation order in the third capability.

[0192] In some embodiments, the use cases in the first or second capability are associated with use cases of reduced capabilities (e.g., industrial wireless sensors, video surveillance, and wearable devices).

[0193] In some embodiments, the PUSCH preparation process time N2 in the second UE processing time is associated with at least one SCS.

[0194] In some embodiments, a larger SCS is associated with a larger N2 value. In other words, N2 has a positive correlation with SCS.

[0195] In some embodiments, N2 corresponding to the first SCS is greater than or equal to 1.1 times N2 corresponding to the second SCS and less than 10 times N2 corresponding to the second SCS, where the first SCS is greater than the second SCS. For example, N2 corresponding to the first SCS can be greater than or equal to 1.25 times N2 corresponding to the second SCS.

[0196] In some embodiments, the N2 value is multiplied by a real number C. In one example, N2 = μ · C (however, the N2 value for SCS = 15 kHz does not use this formula).

[0197] In another example, N2 = d μ · C, as shown in Table 7, where d μ is a real number associated with SCS, and d0 < d1 < d2 < d3.

[0198] Table 7:

[0199] μ PUSCH preparation process time N2 0 <![CDATA[d0·C]]> 1 <![CDATA[d1·C]]> 2 <![CDATA[d2·C]]> 3 <![CDATA[d3·C]]>

[0200] In some embodiments, the PUSCH preparation process time N2 in the second UE processing time is at least associated with the PUSCH preparation process time N2 in the first UE processing time.

[0201] In one example, the PUSCH preparation process time N2 in the second UE's processing time is equal to N2 in the first UE's processing time with the same parameter set multiplied by Cμ, where Cμ is a real number greater than 1 and less than 10 associated with the parameter set. As shown in Table 8 (PUSCH preparation process time N2 in the second UE's processing time).

[0202] Table 8:

[0203] μ PUSCH preparation process time N2 0 10*C0 1 12*C1 2 23*C2 3 36*C3

[0204] In some embodiments, C0 = C1 = C2 = C3, for example, C0 = C1 = C2 = C3 = 2.

[0205] In another example, the PUSCH preparation process time N2 in the second UE's processing time is equal to N2 in the first UE's processing time with the same parameter set plus Dμ, where Dμ is a real number greater than 1 and less than 10 associated with the parameter set.

[0206] In some embodiments, D1 = D2 = D3 = D4.

[0207] In some embodiments, the PUSCH preparation process time N2 in the second UE's processing time is associated with higher layer signaling, which means the N2 value in the second UE's processing time is configured by higher layer signaling.

[0208] In some embodiments, the PUSCH preparation process time N2 in the second UE's processing time is associated with the FR type. For example, N2 in the second UE's processing time associated with FR 2 is greater than N2 in the second UE's processing time associated with FR 1.

[0209] Next, the MAC CE processing time in the second UE's processing time is described according to various embodiments.

[0210] In some embodiments, the MAC CE processing time in the second UE's processing time is associated with at least one of the following: the number of time slots per subframe configured with the subcarrier spacing the MAC CE processing time in the first UE's processing time, higher layer signaling, a predefined value, or UE capabilities.

[0211] In some embodiments, the MAC CE processing time in the second UE's processing time (e.g., T MAC ) is associated with at least and a predefined value. For example, where M is a predefined value and is an integer greater than 3 and less than 10.

[0212] In some embodiments, the MAC CE processing time (T MAC) is at least associated with the MAC CE processing time (T MAC_1 ) in the first UE processing time. In one example, T MAC = T MAC_1 + M1, where M1 is an integer greater than 0 and less than 10. In another example, T MAC = T MAC_1 · M2, where M2 is a real number greater than 1 and less than 10.

[0213] In some embodiments, the MAC CE processing time (T MAC ) in the second UE processing time is configured by higher layer signaling.

[0214] The MAC CE processing time (T MAC_1 ) in the first UE processing time can be:

[0215] Next, the CSI calculation time in the second UE processing time is described according to various embodiments.

[0216] In some embodiments, the CSI calculation time in the second UE processing time is associated with at least one of the following: the reporting amount, UE capabilities, higher layer signaling, the reporting index, SCS, frequency granularity, or the number N of supported simultaneous CSI calculations CPU .

[0217] In some embodiments, the CSI calculation time (N CSI ) in the second UE processing time is at least associated with UE capabilities. In one example, some or all of N CSI are values reported through UE capability reporting. In some embodiments, the UE capability is the beamReportTiming in the second UE processing time.

[0218] In some embodiments, the CSI calculation time (N CSI ) in the second UE processing time is at least associated with the reporting amount. The reporting amount is a CSI-related quantity to be reported by the UE, such as the Layer Indicator (LI), L1 Reference Signal Received Power (RSRP), L1 Signal to Interference plus Noise Ratio (SINR), CSI-RS Resource Indicator (CRI), and Synchronization Signal Block Resource Indicator (SSBRI).

[0219] In some embodiments, for different reporting amounts, some or all of the N in the second UE processing time CSI are the same value. In one example, some or all of the N in the second UE processing time for reporting L1-RSRP and L1-SINR CSI are the same. In another example, some or all of the N in the second UE processing time for reporting CRI and SSBRI CSI are the same.

[0220] In some embodiments, the CSI calculation time (N CSI ) in the second UE processing time is at least associated with the higher layer signaling. In one example, different values configured by the higher layer signaling will be associated with different CSI calculation times. In another example, if the higher layer signaling is configured, the CSI calculation time is the first value; otherwise, the CSI calculation time is the second value. In another example, the CSI calculation time is configured by the higher layer signaling.

[0221] In some embodiments, the CSI calculation time (N CSI ) in the second UE processing time is at least associated with the reported index. If DCI triggers a CSI report in PUSCH, one or more CSI reports will be sent. Since the UE should decode the DCI and prepare the CSI report before sending the first CSI report, the N of the first (or index 1) CSI report CSI is greater than the other N CSI .

[0222] For example, for CSI reports triggered by the same DCI, the N of the first CSI report CSI is the same as the N of another CSI report CSI plus C1. In some embodiments, C1 is a real number greater than 0. For example, C1 is the PDCCH decoding time in the second UE processing time.

[0223] In some embodiments, the CSI calculation time (N CSI ) in the second UE processing time is at least associated with the frequency granularity. In one example, the CSI calculation time (N CSI ) in the second UE processing time for wideband frequency granularity is less than or equal to the CSI calculation time (N CSI ) in the second UE processing time for sub-band frequency granularity.

[0224] In some embodiments, the CSI calculation time (N CSI ) in the second UE processing time is associated with the SCS. In one example, N CSI = d μ· C2, where C2 is a real number greater than 0 and less than 100, d μ is an integer greater than 0 associated with the SCS.

[0225] In some embodiments, the CSI calculation time (N CSI ) in the second UE processing time is at least associated with the number N CPU of supported simultaneous CSI calculations. In one example, the larger of the N CPU is not associated with the smaller of the N CSI . In another example, if N CPU is less than a threshold, the value of N CSI is 1, otherwise, the value of N CSI is 2.

[0226] Next, the PDCCH decoding time in the second UE processing time is described according to various embodiments.

[0227] The PDCCH decoding time in the second UE processing time is associated with at least one of the following: SCS, Control Resource Set (CORESET), search space set, DCI format, Radio Network Temporary Identifier (RNTI), UE capability, predefined value, higher layer signaling, or UE type.

[0228] In some embodiments, the PDCCH decoding time (N PDCCH ) is associated with the SCS. In one example, a larger SCS will not be associated with a smaller PDCCH decoding time. In another example, N PDCCH = y μ · C3, where C3 is a positive real number less than 20, and y μ is a positive real number less than 10 associated with the SCS (see Table 9 below).

[0229] Table 9:

[0230] μ PDCCH decoding time 0 <![CDATA[y0·C3]]> 1 <![CDATA[y1·C3]]> 2 <![CDATA[y2·C3]]> 3 <![CDATA[y3·C3]]>

[0231] In some embodiments, the PDCCH decoding time in the second UE processing time is at least associated with the UE capability. For example, the UE can report the PDCCH decoding time UE capability, and the PDCCH decoding time is determined based on the reported UE capability value.

[0232] In some embodiments, the PDCCH decoding time in the second UE processing time is associated with a predefined value. In some embodiments, the predefined value is different for different SCSs.

[0233] In some embodiments, the PDCCH decoding time in the second UE processing time is associated with the higher layer signaling. For example, the PDCCH decoding time in the second UE processing time is configured by the higher layer signaling.

[0234] Next, according to various embodiments, a first condition is defined.

[0235] The first condition includes at least one of the following: higher layer signaling, UE capability, UE type, DCI, RNTI, Bandwidth Part (BWP), TBS, modulation order, CORESET, search space set, UE category, or random access preamble (at least one of sequence or resource or format).

[0236] In some embodiments, the first condition includes UE capability.

[0237] The UE capability includes at least one of the following:

[0238] 1. PDSCH - processingType capability

[0239] In some embodiments, if the UE reports a UE capability indicating that the UE supports the PDSCH processing time in the second UE processing time, the PDSCH processing time in the second UE processing time will be used.

[0240] In the present disclosure, "will be used" may be equal to "is used".

[0241] In some embodiments, if the UE does not report a UE capability indicating that the UE supports the PDSCH processing time in the second UE processing time, the PDSCH processing time in the first or third UE processing time will be used.

[0242] In some embodiments, the UE capability indicating that the UE supports the PDSCH processing time in the second UE processing time includes a parameter indicating whether the UE supports 1, 2, 4, and / or 7 unicast PDSHs with different transport blocks per time slot for each Component Carrier (CC) in the second UE processing time.

[0243] In some embodiments, if this capability is indicated, the UE may include at least one of the transport blocks with a numberOfCarriers value of 1, 2, 4, or 7 per time slot.

[0244] 2. pusch - processingType capability

[0245] In some embodiments, if the UE reports a UE capability indicating that the UE supports the PUSCH preparation time in the second UE processing time, the PUSCH preparation time in the second UE processing time will be used.

[0246] In some embodiments, if the UE does not report a UE capability indicating that the UE supports the PUSCH preparation time in the second UE processing time, the PUSCH preparation time in the first or third UE processing time will be used.

[0247] In some embodiments, the UE capability indicating that the UE supports the PUSCH preparation time in the second UE processing time includes parameters indicating whether the UE supports 1, 2, 4, and / or 7 unicast PUSCHs with different transport blocks per time slot for each CC. In some embodiments, if this capability is indicated, the UE may include at least one of 1, 2, 4, or 7 transport blocks with a numberOfCarriers value per time slot.

[0248] 3. PDCCH Decoding Capability

[0249] In some embodiments, if the UE reports a UE capability indicating that the UE supports the PDCCH decoding time in the second UE processing time, the second UE processing time will be used.

[0250] In some embodiments, if the UE does not report a UE capability indicating that the UE supports the PDCCH decoding time in the second UE processing time, the first or third UE processing time will be used.

[0251] In some embodiments, the UE capability indicating that the UE supports the PDCCH decoding time in the second UE processing time is associated with the capability indicating that the UE supports the PUSCH preparation time in the second UE processing time.

[0438] - The maximum number of MIMO layers is 4

[0439] - The maximum modulation order is 4

[0440] - Supported types of half-duplex FDD operation.

[0441] Next, if the second UE processing time is used or the conditions for the second UE processing time are met, other settings are described according to various embodiments.

[0442] In some embodiments, when at least one of the following conditions is met, N1 in the second UE processing time is used: the higher layer signaling enables N1 in the second UE processing time and the second UE processing time capability is configured.

[0443] In some embodiments, if N1 in the second type of UE processing time is used (or applied), the associated time associated with the second type of UE processing time can be determined.

[0444] The associated time includes at least one of the following:

[0445] 1. The minimum time between the last symbol of the PDSCH corresponding to the SI-RNTI and the start symbol of the retransmission of the earlier PDSCH;

[0446] 2. The duration from the last symbol of the PDCCH to the first symbol of the HARQ-ACK information;

[0447] 3. The duration between the last symbol of the second DCI indicating the second resource of the PUCCH and the first symbol of the PUCCH resource indicated by the first DCI, where it is expected that the UE multiplexes the HARQ-ACK information corresponding to the second DCI format in this PUCCH resource, or within the duration of a PRACH procedure.

[0448] In some embodiments, in a given scheduled cell, for any PDSCH corresponding to a System Information (SI)-Radio Network Temporary Identifier (RNTI), the UE does not need to decode the retransmission of a previous PDSCH whose starting symbol is less than N symbols after the last symbol of the PDSCH, where the value of N depends on the PDSCH subcarrier spacing configuration μ and the N1 processing time. For example, if N1 in the first or third UE processing time is used, then N = 13 when μ = 0, N = 13 when μ = 1, N = 20 when μ = 2, and N = 24 when μ = 3. If N1 in the second UE processing time is used, the value of N is increased by X1, where X1 is a positive number and less than 20. For example, X1 = 3. In another example, X1 is associated with the SCS.

[0449] In some embodiments, the duration from the last symbol of the PDCCH to the first symbol of the HARQ-ACK information is N symbols. The value of N is associated with the SCS and higher layer signaling. For a serving cell with a PDCCH, if processingType2Enabled of PDSCH-ServingCellConfig is set to enable, then N = 5 when μ = 0, N = 5.5 when μ = 1, and N = 11 when μ = 2. If the higher layer signaling enabling the second UE processing time for a serving cell with a PDCCH is set to be enabled, then N = 10 + X2 when μ = 0, N = 12 + X3 when μ = 1, N = 22 + X4 when μ = 2, and N = 25 + X5 when μ = 3. Otherwise, N = 10 when μ = 0, N = 12 when μ = 1, N = 22 when μ = 2, and N = 25 when μ = 3, where μ corresponds to the minimum SCS configuration between the SCS configuration of the PDCCH and the SCS configuration of the PUCCH carrying the HARQ-ACK information.

[0450] In some embodiments, the duration from the last symbol of the PDCCH to the first symbol of the HARQ-ACK information is N symbols. The value of N is associated with the SCS and the UE processing time type. For example, the value of N in the case of using N1 in the second UE processing time is greater than the value of N in the case of using N1 in the first or third UE processing time.

[0451] The PDCCH is at least one of the following: a PDCCH that provides SPS PDSCH release, a PDCCH that provides DCI format 1_1 indicating the dormancy of a secondary cell (SCell). The HARQ-ACK information responds to the detection of SPS PDSCH release or DCI format 1_1. X2, X3, X4, X5 can be positive numbers and can be less than 20. For example, X2 = X3 = X4 = X5 = 4.

[0452] In some embodiments, referring to Figure 4 , if the UE detects a first DCI (DCI 1) format indicating a first resource of a PUCCH (PUCCH 1) transmitting with corresponding HARQ-ACK information in a time slot and later detects a second DCI (DCI 2) format indicating a second resource of a PUCCH (PUCCH 2) transmitting with corresponding HARQ-ACK information in that time slot, if the duration (time 1) is less than N3 · (2048 + 144) · κ · 2 - μ · T C , then the UE does not need to multiplex the HARQ-ACK information corresponding to the second DCI format in the PUCCH resources in the time slot, where κ is the ratio of T S and T C , T C is the basic time unit of NR, T S is the basic time unit of LTE, and μ corresponds to the minimum SCS configuration among the SCS configurations of the PDCCH providing the DCI format and the SCS configuration of the PUCCH. N3 is associated with the SCS and the UE processing time type. In some embodiments, if for the serving cell with the second DCI format and for all serving cells with corresponding HARQ-ACK information multiplexed in the PUCCH transmission in the time slot, processingType2Enabled of PDSCH-ServingCellConfig is set to enable, N3 = 3 when μ = 0, N3 = 4.5 when μ = 1, N3 = 9 when μ = 2; if the second UE processing time is used, N3 = 8 + X6 when μ = 0, N3 = 10 + X7 when μ = 1, N3 = 17 + X8 when μ = 2, N3 = 20 + X9 when μ = 3, otherwise, N3 = 8 when μ = 0, N3 = 10 when μ = 1, N3 = 17 when μ = 2, N3 = 20 when μ = 3, where X6, X7, X8, X9 can be positive numbers and can be less than 20. For example, X6 = X7 = 4, X8 = X9 = 8. In another example, X6, X7, X8, X9 are associated with the SCS. In some embodiments, the N3 value of the second UE processing time is greater than the N3 value of the first or third UE processing time.

[0453] In some embodiments, during the PRACH procedure, the duration (Time 2) is associated with the PDSCH processing time. If N1 in the second UE processing time is used, then Time 2 is associated with N1 in the second UE processing time; otherwise, when additional PDSCH DM-RS is configured, Time 2 is associated with N1 of UE processing capability 1.

[0454] The duration (Time 2) can be at least one of the following:

[0455] - The time between the last symbol of the PDSCH reception for transmitting the RAR message with the RAR UL grant and the first symbol of the corresponding PUSCH transmission scheduled by the RAR UL grant;

[0456] - The time between the slot for receiving the timing advance command and the symbol to which the corresponding adjustment of the uplink transmission timing is applied, where the timing advance command is for transmissions other than the PUSCH scheduled by the RAR UL grant or the PUCCH with HARQ-ACK information in response to successRAR;

[0457] - The time between the last symbol of the window or the last symbol of the PDSCH reception and the first symbol of transmitting the PRACH (if the higher layer instructs the physical layer to transmit the PRACH), where the window is the ra-ResponseWindow or the msgB-ResponseWindow;

[0458] - The time between the last symbol of the PDSCH reception with the UE contention resolution identity and the first symbol of the corresponding PUCCH transmission with HARQ-ACK information.

[0459] Next, N2 in the second UE processing time is at least described according to various embodiments.

[0460] In some embodiments, during the PRACH procedure, the duration (Time 3) is associated with the PUSCH processing time (N2). If N2 in the second UE processing time is used or the higher layer signaling associated with N2 in the second UE processing time is set to enabled, then Time 3 is associated with N2 in the second UE processing time; otherwise, Time 3 is associated with N2 of UE processing capability 1.

[0461] The duration can be at least one of the following: the time between the last symbol of PDCCH command reception and the first symbol of PRACH transmission (if requested by the higher layer); or the time between the slot in which the timing advance command is received and the symbol to which the corresponding adjustment of the uplink transmission timing is applied, where the timing advance command is for transmissions other than PUSCH scheduled by RAR UL grant or PUCCH with HARQ-ACK information in response to successRAR.

[0462] In some embodiments, for single cell operation or for carrier aggregation operation in the same frequency band, the UE does not transmit PRACH and PUSCH / PUCCH / SRS in the same slot, or when the gap between the first or last symbol of PRACH transmission in the first slot and the last or first symbol of PUSCH / PUCCH / SRS transmission in the second slot is less than N symbols respectively, the UE does not transmit PRACH and PUSCH / PUCCH / SRS. N is associated with the SCS or UE processing time type or higher layer signaling. In some embodiments, if N2 in the second UE processing time is used or the higher layer signaling associated with N2 in the second UE processing time is set to enabled, N = X10 when μ = 0 or μ = 1, N = X11 when μ = 2 or μ = 3, otherwise, N = 2 when μ = 0 or μ = 1, N = 4 when μ = 2 or μ = 3, and μ is the SCS configuration of the activated UL BWP, where X10 and X11 can be positive numbers and can be less than 10. In some embodiments, X10 ≥ 2, X11 ≥ 4.

[0463] Next, the available value ranges of K0, K1, K2, CSI-RS trigger offset, SRS offset, K0min, and K2min for the second UE processing time are described according to various embodiments.

The first maximum available value of the SRS offset can be 15. The second maximum available value of the SRS offset can be V3.

[0473] In some embodiments, if the second UE processing time is used, the second available value range of K0min or K2min is applied, otherwise the first available value range of K0min or K2min is applied.

[0476] In the present disclosure, K0 can be the slot offset between the DCI and the PDSCH it schedules.

[0477] In the present disclosure, K2 can be the slot offset between the DCI and the PUSCH it schedules.

[0478] In the present disclosure, K0min can be the minimum value of K0. The minimum K0 parameter represents the minimum available value of the Time Domain Resource Allocation (TDRA) table of the PDSCH and the CSI-RS trigger offset.

[0480] In the present disclosure, K1 (or dl-DataToUL-ACK) can be the slot offset between the PDSCH and HARQ or the slot offset between the DCI and HARQ.

[0481] In the present disclosure, the aperiodic CSI-RS triggering offset may be the offset between the time slot of the DCI that triggers the aperiodic NZP CSI-RS resource set and the time slot that transmits the CSI-RS resource set.

[0482] In the present disclosure, the SRS offset may be the offset of the number of time slots between the triggering DCI and the actual transmission of the SRS-ResourceSet.

[0483] Next, the MAC-CE processing time in the second UE processing time will be described according to various embodiments.

[0484] In some embodiments, the duration between the PUCCH having HARQ-ACK information corresponding to the PDSCH and the time slot applying the indication carried by the PDSCH is (Time 4). The value of Time 4 is determined according to the first condition. According to the first condition, the value of Time 4 is the MAC-CE processing time in the first UE processing time or the MAC-CE processing time in the second UE processing time.

[0485] In some embodiments, the PDSCH carries at least one of the following: the PDSCH carrying an activation command and indicating the mapping between the TCI state and the code point of the DCI field "transmission configuration indication"; the PDSCH carrying an activation command and indicating a semi-persistent reporting setting; the PDSCH carrying a deactivation command and indicating the deactivation of the SP CSI-RS / CSI-IM resource set; the PDSCH carrying an activation command for a secondary cell.

[0486] In some embodiments, when the UE receives a secondary cell activation command ending in time slot n in the PDSCH, the UE takes corresponding actions no earlier than time slot n + k (where n and k are integers), except for the following actions:

[0487] - Actions related to CSI reporting of the serving cell activated in time slot n + k,

[0488] - Actions taken by the UE in time slot n + k related to the sCellDeactivationTimer associated with the secondary cell, and

[0489] - Actions related to CSI reporting of the serving cell not activated in time slot n + k and taken by the UE in the earliest time slot after time slot n + k when the serving cell is activated.

[0490] Note that the value of k is associated with K1 and the MAC CE processing time in the UE processing time.

[0491] Next, the PDCCH decoding time in the second UE processing time will be described according to various embodiments.

[0492] In some embodiments, if the PDCCH decoding time in the second UE processing time is used, or the first condition for the UE to use the second UE processing time is met, or the second UE processing time is used, the first time type will be different from the time for PDCCH decoding using the first or third UE processing time. The first time includes at least one of the following: BWP switching delay time, beam switching time, beam reporting time, Slot Format Indication (SFI) application time, Channel Occupancy (CO) application time, Quasi Co-Location (QCL) duration, search space switching application time, cross-slot scheduling application delay time, minimum time gap, or energy saving offset.

[0493] In some embodiments, the first time type when using the PDCCH decoding time in the second UE processing time or the second UE processing time is greater than the second time type when using the PDCCCH decoding time in the first or third UE processing.

[0494] In some embodiments, the BWP switching delay time (TBWPswitchDelay) is used for DCI-based BWP switching. After the UE receives a BWP switching request in the DL slot n of the serving cell, the UE should be able to receive the PDSCH (for DL activation of BWP switching) or transmit the PUSCH (for UL activation of BWP switching) on the DL or UL slot of the new BWP on the serving cell after the DL slot n + TBWPswitchDelay on the serving cell. In some embodiments, the BWP switching delay time is the time to switch the BWP.

[0495] In some embodiments, the beam switching time can be the minimum number of OFDM symbols between the DCI trigger of the aperiodic CSI-RS and the aperiodic CSI-RS transmission.

[0496] In some embodiments, the beam reporting time can be the SFI application time, which can be the time between the DCI carrying the SFI and the slot / symbol to which the indicated SFI is applied.

[0497] In some embodiments, the CO application time can be the time between the DCI carrying the CO duration and the slot / symbol to which the indicated CO duration is applied.

[0498] In some embodiments, the QCL duration can be the minimum number of OFDM symbols required for the UE to perform PDSCH processing using the spatial QCL information received in the PDCCH reception and the applied DCI.

[0499] In some embodiments, the search space switching time may be the minimum number of symbols / slots between the PDCCH and the slot of the search space set indicated by the application.

[0500] In some embodiments, the cross-slot scheduling application delay time may be the time between the DCI indicating the minimum scheduling offset change and the slot of the minimum scheduling offset indicated by the application.

[0501] In some embodiments, the minimum time gap may be the time between the time when the UE is not required to monitor the PDCCH to detect DCI format 2_6 and the slot when the UE will start the drx-onDurationTimer.

[0502] In some embodiments, the energy saving offset may be the time between the time when the UE starts to monitor the PDCCH to detect DCI format 2_6 according to the number of search space sets and the slot when the drx-onDuarationTimer will start on the primary cell (PCell) or the special cell (SpCell).

[0503] In some embodiments, if the PDCCH decoding time in the second UE processing time is used or the first condition for the UE to use the second UE processing time is satisfied, the first time type (T_2) is determined by the first time type and the factor (B1) in the first or third UE processing time (T_1). B1 may be a positive number and may be less than 20.

[0504] In some embodiments, the first time type is at least one of the following: BWP switching delay time, beam switching time, beam reporting time, duration of quasi co-location (QCL), search space switching application time, cross-slot scheduling application delay time, minimum time gap, or energy saving offset. For example, T_2 = T_1 + B1. For another example, T_2 = T_1 * B1. In some embodiments, B1 is associated with at least one of the following: SCS, PDCCH decoding time, number of repetitions, or higher layer signaling.

[0505] In some embodiments, if the PDCCH decoding time in the second UE processing time is used, or the first condition for the UE to use the second UE processing time is satisfied, the specific higher layer signaling configures the first time type (T_2) for this case. In some embodiments, the first time type is configured to be associated with the SCS. In other words, different SCSs may configure different first time type values.

[0506] Next, cross-carrier scheduling is described according to various embodiments.

[0507] In some embodiments, if the PDCCH carrying the scheduling DCI is received on a carrier with one OFDM subcarrier spacing, the PDSCH scheduled by the DCI is received on another carrier with another OFDM subcarrier spacing.

[0508] If μPDCCH < μPDSCH, then if the first symbol (including DM-RS) in the PDSCH allocation defined by the slot offset K0 and the start and length indicator SLIV of the scheduling DCI does not start earlier than the first symbol of the PDSCH slot starting from at least Npdsch PDCCH symbols after the end of the PDCCH scheduling the PDSCH, it is expected that the UE receives the scheduled PDSCH, regardless of the effect of the reception timing difference between the scheduling cell and the scheduled cell.

[0509] If μPDCCH > PDSCH, then if the first symbol (including DM-RS) in the PDSCH allocation defined by the slot offset K0 and the start and length indicator SLIV indicated by the scheduling DCI does not start earlier than Npdsch PDCCH symbols after the end of the PDCCH scheduling the PDSCH, the UE expects to receive the scheduled PDSCH, regardless of the effect of the reception timing difference between the scheduling cell and the scheduled cell.

[0510] In some embodiments, Npdsch associated with the first or third UE processing time is less than Npdsch associated with the second UE processing time.

[0511] In some embodiments, if the first or third UE processing time is used, Npdsch can be based on Table 10 below, and if the second UE processing time is used, Npdsch can be based on Table 11 below. In some embodiments, P1 > 4, P2 > 5, P3 > 10, P4 > 14. In some embodiments, P2 > 1.5 * P1, P3 > 1.5 * P2, P4 > 1.5 * P3.

[0516] In summary, it is apparent from the foregoing description that the embodiments include one or more of the following aspects:

[0517] In some embodiments, UE processing time is applied based on a first condition (e.g., to perform, schedule, or operate a transmission).

[0518] In some embodiments, the UE processing time may include a first UE processing time, a second UE processing time, and a third UE processing time.

[0519] In some embodiments, each UE processing time may include at least one of the following: Physical Downlink Shared Channel (PDSCH) processing time N1, Physical Uplink Shared Channel (PUSCH) preparation process time N2, Medium Access Control (MAC) Control Element (CE) processing time, Channel State Information (CSI) calculation time, or Physical Downlink Control Channel (PDCCH) decoding time.

[0520] Specifically, the second UE processing time allows a more relaxed time than the first UE processing time. The third UE processing time only includes N1 and N2.
