[0022] FIG. 1 shows an example of the structure of a radio frame used in NR.

[0023] In NR, uplink (UL) and downlink (DL) transmissions are organized into frames. A radio frame has a length of 10 ms and consists of two 5 ms half-frames (Half-F A half frame is defined as five 1 ms subframes (Subframes, HF). A subframe is divided into one or more slots. The number of slots in each slot depends on the SCS (Subcarrier Spacing). The lot consists of 12 or 14 OFDM(A) systems depending on the CP (cyclic prefix). If a general CP is used, each slot contains 14 symbols. If CP is used, each slot contains 12 symbols, where the symbols are O FDM symbol (or CP-OFDM symbol), SC-FDMA symbol (or DFT-s-OFDM symbols).

[0024] Table 1 shows the number of symbols per slot, frame rate, and frame rate per frame, depending on the SCS when a general CP is used. This shows an example of the number of slots per frame and the number of slots per subframe changing. .

[0025] [Table 1]

[0026] Table 2 shows how the SCS determines the number of symbols per slot, frame rate, and frame rate when extended CP is used. This shows an example of the number of slots per frame and the number of slots per subframe changing. .

[0027] [Table 2]

[0028] In the NR system, the mobile stations are merged into one terminal (User Equipment: UE). OFDM(A) neurology (e.g., SCS, CP length, etc.) differs among multiple cells. This allows for a time resource consisting of the same number of symbols (e.g. , SF, slot or TTI) (for convenience, collectively referred to as TU (Time Unit)) The intervals differ between the merged cells.

[0029] NR will support a variety of 5G services using a number of Orthogonal Frequency Division Multiplexing (OFDM) schemes. Frequency Division Multiplexing) Pneumologic (e.g. For example, if the SCS is 15 kHz, the traditional Supports wide area in the general cellular band, SCS is 30 kHz z / 60kHz, dense-urban, lower latency ( lower latency and wider carrier bandwidth Supports bandwidth.

[0030] The NR frequency bands are divided into two types of frequency ranges (F R) (FR1 / FR2). FR1 / FR2 is configured as shown in Table 3 below. FR2 stands for millimeter wave (mmW). .

[0031] [Table 3]

[0032] Figure 2 shows an example of the slot structure of an NR frame.

[0033] A slot contains multiple symbols in the time domain. For example, in the case of a general CP, one A slot contains 14 symbols, but in the case of extended CP, one slot contains 12 symbols. A carrier contains multiple subcarriers in the frequency domain. e Block) is defined as a number (e.g., 12) of consecutive subcarriers in the frequency domain. In the frequency domain, multiple RB interlaces (or simply interlaces) are defined. Interlace m∈[0, 1, ..., M-1] is (common) RB[m, M+m, 2M+m , 3M+m, ...], where M indicates the number of interlaces. dth Part) is a part of multiple consecutive RBs (e.g., physical RBs) in the frequency domain. B, PRB) and one OFDM numerology (e.g. For example, SCS(u), CP length, etc.) can be supported. The maximum number of carriers is N (for example, 5 ) BWP. Data communication is performed in the activated BWP and is performed within one cell / carrier. In the resource grid, only one BWP is activated for each terminal. The elements are called resource elements (RE) and are used for one modulation. The symbols can be mapped.

[0034] In a wireless communication system, a terminal receives downlink (DL) signals from a base station. The terminal receives information via the uplink (UL) and transmits the information to the base station. The information transmitted and received between the base station and the terminal includes data and various control information. There are various physical channels / signals depending on the type / purpose of the information being transmitted / received. A channel corresponds to a set of Resource Elements (RE) that carry information originating from a higher layer. The signal corresponds to a set of resource elements (RE) used by the physical layer (PHY), but It does not carry information originating from the higher layer. The higher layer is MAC (Medium Access Control). ontrol) layer, RLC (Radio Link Control) layer, PDCP (Pa cket Data Convergence Protocol) layer, RRC (Radio o Resource Control) hierarchy.

[0035] The DL physical channel is PBCH (Physical Broadcast Channel) el), PDSCH (Physical Downlink Shared channel) and PDCCH (Physical Downlink Control channel) DL physical signals include DL RS (Reference Signal), PSS (Pri mary synchronization signal) and SSS (Secondary Synchronization Signal) DL RS includes DM-RS (D emodulation RS), PT-RS(Phase-tracking RS) and Includes CSI-RS (Channel-state information RS). The physical channel is PRACH (Physical Random Access Channel) el), PUSCH (Physical Uplink Shared Channel) and Includes PUCCH (Physical Uplink Control Channel). The UL physical signal includes UL RS. UL RS includes DM-RS, PT-RS and SRS (So undering RS).

[0036] FIG. 3 shows an example of mapping physical channels within a slot.

[0037] In one slot, DL control channel, DL or UL data, and UL control channel For example, the first N symbols in a slot are DL control channels. The DL control region is used to transmit the last M symbols in a slot. The UL control region is used to transmit the UL control channel (hereafter referred to as the UL control region). N and M are 0 and The resource area between the DL control area and the UL control area (hereinafter referred to as the data area) is an integer equal to or greater than 1. is used for transmitting DL data or is used for transmitting UL data. Between the control and data domains, there is a DL-to-UL or UL-to-DL switching There is a time gap for PDCCH transmission in the DL control region and for DL ​​data region. PDSCH is transmitted at the time of switching from DL to UL within the slot. symbols are used as time gaps.

When a signal is received, the terminal performs transform precoding. For example, when transform precoding is not possible ( (e.g., transform precoding is disabled), the terminal is CP-O Transmit PUSCH based on FDM waveform and, if transform precoding is possible (e.g., transform precoding is enabled), and the terminal is CP-OFDM PUSCH is transmitted based on the PD waveform or DFT-s-OFDM waveform.

[0115] Higher frequency bands than the FR1 and FR2 bands (e.g., 52.6 GHz to 114.25 The 52.6GHz to 71GHz band is called FR2-2. Waveform, SCS, CP length, and timing defined for FR1 and FR2 in the stem (timing) etc. do not need to be applied to FR2-2.

[0116] For NR operation in the band above 52.6 GHz, 120 kHz, 480 kHz z, 960kHz SCS will be used. Newly introduced 480kHz, 960kHz In the case of SCS, the length of the OFDM symbol is shorter (e.g., 48 (0kHz is 1 / 4 times, 960kHz is 1 / 8 times). Shortened symbol length and slot length Depending on the length, the PDCCH / PDSCH processing time , various times such as PDSCH / PUSCH preparation time Changes may occur in the timeline. Because the influence of noise is large, ICI (Integrated Coherence Index) is large when the terminal decodes the PDSCH. This further increases the time required for compensation for carrier interference. On the other hand, the newly introduced multi-PDSCH scheduling using a single DCI (multi-PDSCH scheduling) -PDSCH scheduling by single DCI) DCCH processing time increases. Also, PDSCH-to-HARQ-ACK (K 1) When setting the required time (number of symbols and / or number of slots), changes are expected. The implementation complexity of the terminal (UE) due to the short symbol / slot time is To reduce the burden of staging complexity, changes in the timeline are required. This allows for NR operation in the corresponding band, and requires a PDSCH processing time. The time required for the PUSCH preparation (N2), HARQ-ACK processing (N3) The slot off time from DL grant reception to PDSCH reception is Set (K0), slot offset from PDSCH reception to HARQ-ACK transmission (K 1) Change in the slot offset (K2) setting from UL grant reception to PUSCH transmission Furthermore, DCI (or PDCCH) that triggers CSI-RS, CSI-RS and / or CSI-IM signals and / or CSI reports transmitted by This also requires timeline changes between UL channels.

[0117] In the present invention, in high frequency (e.g., 52.6 GHz or higher) / wideband NR operation, Newly introduced SCS (e.g., 480, 960 kHz) and the resulting shortened synchro Changes in timeline aspects due to bolt / slot length, specific K0, K1, K2 values This section explains how to set the DCI that triggers the CSI-RS and the associated The timing of the CSI-RS / IM signal that transmits the CSI report and the PUSCH that transmits the CSI report is also important.

[0118] 1.1. How to change the range of K1 values ​​to match the range of N1 values

[0119] 1.1.1-1. DCI Format 1_0

[0120] When PDSCH scheduling is performed using DCI format 1_0, CH-to-HARQ_Feedback Timing Indicator (PDSCH-to-HARQ The _feedback timing indicator field is 3 bits (bit ) to indicate one of the values ​​[1, 2, 3, 4, 5, 6, 7, 8]. The -to-HARQ_Feedback Timing Indicator field is hereinafter referred to as the K1 field. The specified value is used to determine the last slot of the PDSCH received by the terminal. PUCCH (or PUSCH) slots for transmitting HARQ-ACK associated with PDSCH On the other hand, the slot interval between PDSCH reception, PDSCH decoding and HARQ-A The terminal reports the time required for CK processing to the base station. When the time required for PDSCH decoding and HARQ-ACK processing is N1, N 1 is expressed in symbol units. After the N1 value is reported, the base station Set the PDSCH-to-HARQ_feedback value to be equal to or greater than the HARQ-ACK for PDSCH and PUCCH (or PUSCH, PDSCH) Set the slot offset between the high SCS ( For example, if a frequency band (480, 960 kHz) is set, the slot length is very short and the terminal ,After receiving PDSCH, it takes a long time to prepare HARQ-ACK, so K Of the values ​​of 1 field [1, 2, 3, 4, 5, 6, 7, 8], 1 is actually used. It may not be possible.

[0121] Table 8 shows the conventional 3GPP 38.214 Table 5.3-1: PDSCH pr ocessing time for PDSCH processing capabil ity 1, indicating the defined N1 value.

[0123] If SCS (or pneumology) is 960 kHz (in this case μ = 6), 2 For example, if N1>28, the PDSCH-to-HA Among the RQ_feedback field values, values ​​of 2 or less are not required. Therefore, the N1 value If necessary, the HARQ_Flag is set to indicate the further requested value instead of the unused value. Two different interpretations of the feedback field values ​​are useful: By using this method, the PDSCH-to-HARQ_feedback field is While still using (i.e., without increasing the value and bitwidth), N Instead of a small value that is not used according to 1, another value can be set as K1.

[0126] In 1.1-(1) and 1.1-(2), c is semi-statically set by RRC, MAC CE, etc. The default c value is set by the s The number of symbols per lot is 14. Method 1.1-(1) for determining K1 is as follows: Using the ceiling function, add the smallest integer equal to or greater than N1 / c to the K1 field value. The method 1.1-(2) for determining K1 is to use the floor function to find N1 / c This is a method of adding the largest integer below to the K1 field value. If N1 is a multiple of c, then: The K1 field values ​​determined by 1.1-(1) and 1.1-(2) are the same. For example, when c=14, according to 1.1-(2), depending on the range of N1 value, The K1 value is determined as follows.

[0127] If N1 is less than 14, then K1 = [1, 2, 3, 4, 5, 6, 7, 8]

[0128] If N1 is greater than or equal to 14 and less than 28, K1 = [2, 3, 4, 5, 6, 7, 8, 9]

[0129] If N1 is greater than or equal to 28 and less than 42, K1 = [3, 4, 5, 6, 7, 8, 9, 10]

[0130] ...

[0131] Alternatively, when c=14, according to method (1), K1 is calculated as follows according to N1: A value is defined.

[0132] If N1 is 14 or less, K1 = [2, 3, 4, 5, 6, 7, 8, 9]

[0133] If N1 is greater than 14 and less than or equal to 28, K1 = [3, 4, 5, 6, 7, 8, 9, 10]

[0134] If N1 is greater than 28 and less than or equal to 42, K1 = [4, 5, 6, 7, 8, 9, 10, 11]

[0136] 1.1.1-2. DCI Format 1_1 and DCI Format 1_2

[0137] If PDSCH is scheduled by a DCI format other than DCI format 1_0, When the SPS PDSCH release is triggered by DCI, If scheduled, the RRC IE (information element) dl-DataToUL-ACK or dl-DataToUL-ACK configured by the PUCCH-Config l-DataToUL-ACK-r16 or dl-DataToUL-ACKForD Using CIFormat1_2, the number of bits (bitwidth) of the K1 field and its In this case, the value is determined. -(2) is used to add ceil(N1 / c) or floor(N1 / c) to the K1 field value. The K1 value is set by the method used.

In this case, as in 1.1.1-1, dl- DataToUL-ACK, or dl-DataToUL-ACK-r16, or dl- The value specified by DataToUL-ACKForDCIFormat1_2 is set to ceil The K1 value is set by adding (N1 / c) or floor(N1 / c).

[0140] 1.1.1-4. SPS PDSCH reception

[0141] In addition, the DCI format that activates SPS PDSCH reception is If the K1 field exists in the SPS PD, add X to the K1 field value. The offset between the SCH reception ending slot and the PUCCH transmission slot In this case, X can be defined as (Method 1.1.1-1) can be in the form ceil(N1 / c) or floor(N1 / c), where c is the R It is set by RC / DCI, etc. Or, you can set the X value to a specific number without using N1 and c. It may be pre-defined and determined by higher layer signaling such as RRC. Therefore, it may be set.

[0142] Furthermore, methods 1.1.1-1 through 1.1.1-4 may be used to identify specific SCSs (e.g., 480 , 960kHz). Methods .1-4 operate only when N1 is equal to or greater than a specific value. Also, methods 1.1-(1) and 1.1-(2) in 1.1.1-1 are mutually exclusive. After setting different c values, the K1 settings by Method 1.1-(1) and Method 1.1-(2) In this case, the switch flag (switch) ch flag) is indicated by the DCI.

[0143] In order to apply the methods of 1.1.1-1 to 1.1.1-4, (480 kHz and / or (for 960kHz SCS) N1 value is dmrs-AdditionalPosition There are two different values ​​depending on the ion value. If dmrs-AdditionalPosition='pos0', the relative Aggressive (short) processing times are applied to If AdditionalPosition ≠ 'pos0', or if the upper layer parameter If the meter (higher-layer parameter) is not set, Relative processing times apply.

[0144] For example, 480 kHz and / or 960 kHz used in the FR2-2 band For SCS, the N1 value is calculated by the dmrs-AdditionalPosit It is defined to have two different values ​​depending on the ion value.

[0145] Table 9 is based on Table 5.3-1: PDSCH process in 3GPP 38.214. ssing time for PDSCH processing capability 480 kHz and / or 960 kHz used in the FR2-2 band in relation to 1 The newly defined N1 value for SCS is shown.

[0146] [Table 9]

[0147] This allows us to achieve the ceil(N1 / c) or floor(N1 / c) is a newly defined This is applied by selecting one of two different N1 values.

[0148] (Method 1.1.2-1) The first method is the same as the condition where N1 is divided into two different values. Similarly, depending on the dmrs-AdditionalPosition value, ceil(N1 / c) or floor(N1 / c) is a method for selecting N1 used in In the methods of .1-1 to 1.1.1-4, ceil (N1 / c) or floor (N1 / When calculating c), "dmrs-AdditionalPosition=pos0 i n DMRS-DownlinkConfig in both of dmrs-Down linkForPDSCH-MappingTypeA, dmrs-DownlinkF or PDSCH-MappingTypeB, the N1 value on the left side of Table 9 is used. "dmrs-AdditionalPosition≠pos0 in DMRS-D ownlinkConfig in either of dmrs-DownlinkFo rPDSCH-MappingTypeA,dmrs-DownlinkForPDSC H-MappingTypeB or if the higher layer param If the value is "neter is not configured", the N1 value on the right side of Table 9 Two different N1 values ​​are defined depending on the Additional DMRS setting. Similarly, PDS where Additional DMRS is not configured / used For CH, the smaller of the two N1 values ​​is used to determine the off-state for K1 (or K1). The set is determined and the Additional DMRS is set / used in the PDSCH. For the PDSCH-to-H, the larger of the two N1 values ​​is used to determine K1 (or The offset for the ARQ feedback timing indicator is determined. In this case, the latter (for example, the N1 value on the right side of Table 9) is used as the base value. In other words, the basic setting of dmrs-AdditionalPosition is pos2 Therefore, K1 (or PDSCH-to-HARQ_feedback timing The basic value of dmrs-AdditionalPosition is also the basis for It is determined based on N1 when this value is reached.

[0149] (Method 1.1.2-2) The second method is dmrs-AdditionalPosit This is a method of using the larger of the two N1 values ​​regardless of the ion value. As an example, (using the N1 values ​​in Table 9) in methods 1.1.1-1 to 1.1.1-4 K1 (or PDSCH-to-HARQ_feedback timing in dicator) value is offset by dmrs-AdditionalPosit Regardless of the ion value, floor(24 / 14) for 120kHz SCS, 480kHz SCS: floor (96 / 14), 960kHz SCS: floor (192 / 14 ) Alternatively, use the ceil() function instead of floor() to offset may be determined.

[0150] (Method 1.1.2-3) The third method is dmrs-AdditionalPosit This is a method of using the smaller of the two N1 values ​​regardless of the ion value. As an example, (using the N1 values ​​in Table 9) in methods 1.1.1-1 to 1.1.1-4 K1 (or PDSCH-to-HARQ_feedback timing in dicator) value is offset by dmrs-AdditionalPosit Regardless of the ion value, floor(20 / 14) for 120kHz SCS, 480kHz For SCS, floor (80 / 14), for 960kHz SCS, floor (160 / 14 ) Alternatively, use the ceil() function instead of floor() to offset may be determined.

[0151] When PDSCH scheduling is performed using DCI format 1_0, the K1 frame field (PDSCH-to-HARQ_feedback timing indicator The value defined by the three bits of the byte field is [1, 2, 3, Instead of the traditional 8 values, new values ​​may be defined. Some of the values ​​are defined with the offset proposed in 1.1 above. Some other values ​​are defined by scaling the conventional values. Alternatively, the K1 field value is scaled with the value determined by the offset. Therefore, the maximum value (largest value) or minimum value (smallest value) of the determined values ​​is determined. As an example, the offset value is set using ceil(N1 / 14) (in this case, The N1 value may vary depending on the SCS and / or additional DMRS configuration. In this example, N1=96 for 480 kHz, N=192 for 960 kHz. Assume that ceil(N1 / 14)=7 for 480kHz, ceil(N1 / 14)=14 for 960kHz), scaling value is 480 / 960kHz SC For each of S, use x4 and x8 (in this case, the scaling value is 4 times (480 kHz), 8 times (960kHz) (not limited to), four of the eight conventional values ​​have offsets Apply scaling to the other four (at this time, the offset of the eight values ​​is The number of values ​​changed by scaling and the number of values ​​changed by scaling are also 4 / 4. (It may be set to 0 / 8 or 1 / 7 or 8 / 0), A new value is defined.

[0152] 1.1.1-(1) Apply offset to any of the eight values ​​for 480kHz: 1, 2, 3, 4, 5, 6, 7, 8] -> [8, 9, 10, 11, 12, 13, 14, 15]

[0153] 1.1.1-(2) Apply scaling to any of the eight values ​​for 480kHz: [1, 2, 3, 4, 5, 6, 7, 8] -> [4, 8, 12, 16, 20, 24, 28, 32 ]

[0154] 1.1.1-(3) Apply offset to any of the eight values ​​for 960kHz: 1, 2, 3, 4, 5, 6, 7, 8] -> [15, 16, 17, 18, 19, 20, 21, twenty two]

[0160] Also, when PDSCH is scheduled by DCI format 1_0, K1 field (PDSCH-to-HARQ_feedback timing indicator The value defined by the three bits of the icator field is the same as that of the conventional communication system. 1, 2, 3, 4, 5, 6, 7, 8] values ​​are used as they are, but the terminal (UE) A part of the indicated value is offset depending on the N1 value. Additionally, interpret and / or use other parts of the indicated values ​​to scale conventional values. As an example of this, the base station uses the conventional [1, 2, 3, 4, 5, 6, 7, 8] to the terminal, and the terminal determines the value to be actually applied using the specified value, Some values ​​are offset and some values ​​are scaled. Alternatively, the terminal The maximum value (larger value) of the values ​​determined by the offset and the scaling is determines the minimum value (smallest value) as the value actually used. The offset value is ceil(N1 / 14) (where N1 is the SCS and / or additional DMR The value varies depending on the S setting. In this example, N1=96 for 480 kHz, N=1 92 for 960 kHz), the scaling value is 480 / 960kHz S Using x4 and x8 for each CS (in this case, the scaling value is 4 times (48 0kHz), 8 times (960kHz) and more. Four of the eight previous values ​​are off. Applying a set to four values ​​and scaling to four values ​​(in this case, out of eight values, , the number of values ​​changed by the offset and the number of values ​​changed by scaling are also four. / 4, but may be set to 0 / 8, 1 / 7, or 8 / 0), will interpret and / or apply the eight values ​​as new values ​​as follows:

[0162] 1.1.2-(2) Apply scaling to any of the eight values ​​for 480kHz: [1, 2, 3, 4, 5, 6, 7, 8] is indicated, and [4, 8, 12, 16, 20, 24, 28, 32] applied

[0163] 1.1.2-(3) Apply offset to any of the eight values ​​for 960kHz: 1, 2, 3, 4, 5, 6, 7, 8] is indicated, and [15, 16, 17, 18, 19, 20 , 21, 22] are applied.

[0167] The number of eight K1 field values ​​to which the offset is applied and the scaling applied. The number of values ​​to be used is not limited to the above-described embodiment, and may be predetermined to a ratio of a specific number. For example, Of the eight values, the first four are offset and the last four are scaling. Another example is to use an offset for the first two values ​​and a scaling for the last four values. Another example is to apply offset to the 1st, 3rd, 5th and 7th values ​​of the 8 values. , 2nd, 4th, 6th, and 8th values ​​are scaled. The number and position of values ​​to which offsets are applied in signaling such as ringing and DCI, and the scale The number and position of the values ​​to which the ring is applied may be set. Also, the scaling value may be set as described above. Not limited to the embodiment described above, even if a specific value is predetermined (by SCS or independently of SCS), Alternatively, scaling can be achieved by higher layer signaling such as RRC or DCI. The offset value may be set as proposed in 1.1 above. floor(N1 / c) or ceil(N1 / c) are used.

[0168] Furthermore, by the method described later, the K1 field (PD SCH-to-HARQ_feedback timing indicator fie For systems operating in the 52.6 GHz frequency band, a new value for ld may be determined. When a high SCS (e.g., 480kHz or 960kHz) is set, the DCI The K1 field value of MAT1_0 is the conventional 52 GHz frequency band. Instead of [1, 2, 3, 4, 5, 6, 7, 8] in the system, we use the method described below to The method described below uses the conventional 3-bit, i.e., 8 values The K1 field is then used to generate a higher SCS (e.g., 480 , 960 kHz), PDSCH scheduling flexibility (sched This can improve the problem of low suction flexibility. We will explain two typical examples of problem situations that can occur. First, the conventional [1, 2, 3, 4, 5, 6, 7, 8] are simply scaled by 4 or 8. The granularity of the scheduling has been increased from the previous 1 slot to 4 or 8 slots. Second, if you want to add a specific offset value to the existing value, The scheduling granularity is maintained at 1 slot, but is restricted from the PUCCH at a specific position. The problem arises that PDSCH scheduling is only possible in slots with limited distance. The proposed method described below can avoid the worst-case scenario of these two problem situations. can be done.

[0169] (Proposed method 1.1.k1-1) K1 field of DCI format 1_0 (PDSCH -to-HARQ_feedback timing indicator field) Maintain 3 bits (or extend it to more than 3 bits) and use S above 120 kHz. How to define new values ​​suitable for CS (e.g., 480, 960 kHz). Specifically, Z The 2^Z values ​​that can be represented by bits are constructed according to the following rules: The 2^Z representable values ​​are divided into M subgroups. Each subgroup consists of L consecutive numbers (or numbers in a specific interval). When M and L are integers greater than 0, M*L=2^Z. Also, there are M*L The values ​​of are all different and overlapping numbers are not allowed (here, each subgroup The first subgroup, the second subgroup, and so on, in ascending order of the numbers / values ​​contained in For example, the eight values ​​that can be expressed with 3 bits are called slot groups with M=1. It may consist of L=8 consecutive numbers, M=2 slot groups and each sub Each subgroup may consist of L=4 consecutive numbers, and M=8 subgroups and each It may be composed of L=1 numbers for each subgroup.

[0170] In addition to the aforementioned M and L, the interval between subgroups (= T) in the rules described below and / or the spacing between values ​​within a subgroup (=J), depending on which value you use. Various types of K1 field values ​​are defined. The larger M or T, the larger the range of values. However, the difference in values ​​between subgroups increases, and scheduling granularity J can also adjust the scheduling scope and granularity within the subgroup. For example, if J=1, the UE receives PDSCH in consecutive slots. HARQ-ACK can be supported for J>1, but it is larger than when J>1. This is because the limited Z bit ( Or, when using a set of 2^Z values, a large scheduling Scheduling range and high scheduling granularity It is difficult to simultaneously support the two, and there is a trade-off between them. Therefore, the appropriate schedule for each SCS is In order to ensure flexibility in the rules, the following rules (1.1.3-1) to (1.1.3-3) By appropriate selection / combination of L, T, J, etc., the most suitable set of values ​​for each SCS is obtained. (value set) needs to be defined.

[0171] Rule 1.1.3-1: How to determine the minimum value of the first subgroup (=S1)

[0172] The minimum value of the first subgroup is the floor(N1 / c) or ceil(N1 / c) is used. Or floor(N1 / c) or ceil( N1 / c) is used. If a high SCS (e.g., 48 When multi-slot PDCCH monitoring operation is introduced at By adjusting by +1 or -1, the PDCCH monitoring slot (or slot The slot-group positions and PDSCH receiving slot positions are distributed. N1 may be a predefined value for each SCS, and c may be a value as defined in 1.1 above. For example, the c value may be a value that is predefined for each slot. Alternatively, the first subgroup of the first The minimum value (i.e., the minimum value) may be different for each SCS, depending on the pneumothorax of the SCS. The first value is determined as "2^(u_SCS - 3)" using u_SCS, which indicates the logic. Or "2^(u_SCS - 3) + 1" or "2^(u_SCS - 3) - 1" The first value is determined. u_SCS is calculated as follows: 2^(u_SCS)*15[kHz]=SCS[ For example, for a 120kHz SCS, u_SCS=3 , u_SCS=5 for 480kHz SCS, u_SCS=6 for 960kHz SCS If the PDSCH processing time for a particular SCS is set large, The first value may be determined to be 2^(u_SCS - 2). The required PDSCH processing time for S - 3), this value is very unlikely to be used. , "2^(u_SCS - 2) + 1" or "2^(u_SCS - 2) - 1" plus the first A value may be specified.

[0173] Rule 1.1.3-2: Method for determining the minimum value of a subgroup other than the first

[0174] If M>1, the smallest value of any subgroup other than the first subgroup is , a specific value (=T) from the minimum value of the first subgroup determined in Rule 1.1.3-1, or It is determined as a value that is a multiple of a specific value T. The specific value T differs for each SCS, and T=1 Or it is determined to be a power of two, such as T=2, T=4, T=8, or T=16. For example, The minimum value of the second subgroup is the minimum value of the first subgroup plus T. , the minimum value of the third subgroup is the minimum value of the first subgroup plus 2*T (i.e., the minimum value of the second subgroup plus T), and The minimum value of the next subgroup is the minimum value of the first subgroup plus (n-1)*T (i.e., (i.e., the minimum value of the (n-1)th subgroup plus T).

[0175] Rule 1.1.3-3: For each subgroup, the L-1 values ​​excluding the smallest value are Increase by a specific interval (=J) from the value determined by Rules 1.1.3-1 and 1.1.3-2 The specific interval J varies from SCS to SCS, and J ranges from 0 to are large integers. For example, Z=3, M=1, L=8, J=1, and 480 kHz S For CS, N1=80, and the minimum subgroup value is ceil(N1 / 14)+1=7. In this case, the K1 field value is determined to be [7, 8, 9, 10, 11, 12, 13, 14]. For 960kHz SCS, N1=160 and the minimum value of the subgroup is ceil(N If 1 / 14)+1=13, then the K1 field value is [13, 14, 15, 16, 1 7, 18, 19, 20]. Another example is Z=3, M=4, L=2, T =4 (for 480kHz) or T=8 (for 960kHz), J=1, and the first If the minimum number of subgroups is the same as in the example above, then the For each of these, [7, 8, 11, 12, 15, 16, 19, 20] and [13, 14, 21 , 22, 29, 30, 37, 38].

[0178] The following Examples 1.1.4-1 to 1.1.4-10 were created according to the above rules.

You can subtract values ​​and apply them by dividing the slot index by a specific divisor. modulo the remainder of the received P The slot offset between the UL slots transmitting the corresponding HARQ-ACK from the DSCH is determined. The PDSCH and the PDSCH actually applied by the UE are determined by the following [Equation 1.1.k1-2]. The slot offset between the UL slots is determined.

[0199] [Formula 1.1.k1-2] k1_applied=k1_indicated-mod ulo(slot_index, B)

[0200] In this case, k1_applied is the "PDSCH and corresponding HA" that the UE actually applies. Slot offset between UL slots for RQ-ACK transmission et)" k1_indicated means "PDSCH-t indicated to UE" o-HARQ_feedback timing indicator field value slot_index is the slot index of the slot in which the UE received the PDSCH. The modulo(x, y) operation means the remainder when x is divided by y. The constant B may have different values ​​depending on the SCS, and may be predefined or It may be indicated separately by RRC or DCI. For example, for 480 kHz SCS For 960kHz SCS, B=4 is predefined, and for 960kHz SCS, B=8 is predefined. As a specific example of this, k1_indi for 960 kHz SCS is If cated=[8, 16, 24, 32, 40, 48, 56, 64] is defined, UE In order to transmit HARQ-ACK in slot #n, the UE must slot♯(n-8), slot♯(n-16), ...., slot♯(n-64) In other words, the HARQ-ACK must be received in the corresponding UL slot. To transmit, the schedulable PDSCH receive slots are spaced 8 slots apart. It exists only in the slots between them (i.e., slot♯(n-9), slot♯(n-10) ), ..., slot #(n-15)), the UE receives the PDSCH In some cases, the UE may not be able to send HARQ-ACK at t♯n. However, there may be cases where a valid UL slot is not indicated. By applying [Formula 1.1.k1-2], the UE transfers from slot #(n-16) to slot Even if the UE receives PDSCH in any of the eight slots #(n-9), The HARQ-ACK may be transmitted in response to the

[0201] Furthermore, this behavior can be enabled / disabled via a separate RRC setting (config can be set and / or indicated by the DCI field For example, by using a separate parameter / field of RRC or DCI, [Equation 1.1.k] If you enable the operation of [1-2], the UE will use "indicated k1=16". and HARQ-ACK for PDSCH received in slot #(n-15) is sent to slot #n. Separate parameters / fields of RRC or DCI are If you disable the operation of [Formula 1.1.k1-2] using HARQ-ACK for the PDSCH received in slot #(n-15) is transmitted in slot #(n+1). Furthermore, this behavior can be enabled / disabled by the index (or SFN: system frame number), subframe index It may be implicitly determined depending on the m index, slot index, etc. If modulo(SFN,2)=0, the operation is enabled. If ,2)=1, the behavior is set to [disable], so that even frames (ev This enables the operation every 100 frames. E uses only the K1 field with a limited number of bits (bidwidth) to achieve high SC Increased scheduling flexibility for S (e.g., 480, 960 kHz) You can expect this.

[0202] 1.2. N pdsch and μ PDCCH , μ PDSCH How to change the range of K0 values ​​using cross-carrier scheduling)

[0203] K0 is the number of slots from which DL grant PDCCH is received to which PDSCH is received. A UE configured with K0 shall use the slot offset to the next slot in accordance with 3GPP TS 38. The slot Ks for receiving the PDSCH is determined according to Table 10 defined in 214.

[0204] [Table 10]

[0205] At this time, μ PDCCH , μ PDSCH If the values ​​are different from each other, K0 is PDSCH Standard slot μ is interpreted as a unit of PDSCH >μ PDCCH If K0=0, the PDCCH is received. It means the earliest slot among the PDSCH slots corresponding to the specified slot. μ PDSCH <μ PDCCH If K=0, then K=0 corresponds to the slot in which the PDCCH is received. This refers to the PDSCH slot.

[0206] On the other hand, in cross-carrier scheduling, μ PDCCH , μ PDSCH If the values ​​are different, s Even if is determined by the above formula, K s The position of N symbols from the last symbol received by PDCCH (PDCCH symbol unit) pdsch Shin Only when the PDSCH interval is guaranteed, the terminal can expect normal PDSCH reception. N pdsch is defined in Table 11 of 3GPP TS 38.214.

[0207] Table 11 is based on Table 5.5-1: N in 3GPP TS 38.214. pdsch as a function of the subcarrier spacing of the scheduling PDCCH.

[0209] Newly introduced 480kHz and 960kHz SCS for the 52.6GHz band For μ PDCCH = 5, μ PDCCH N corresponds to =6 pdsch From Table 11, we can infer that It is set to a value greater than 4.

[0210] As mentioned above, mixed S If CS, slot K s Even if the last symbol of PDCCH is determined by K0, From Bolu to N pdschIf the interval for the number of symbols is not guaranteed, the terminal will not expect to receive the PDSCH. Since there is no need to wait, a specific value of K0 is not required. pdsch >N pdcch If the PDCCH is received in the slot, the last PDCCH received is The number of unnecessary K0s (for which PDSCH reception is not expected) varies depending on the symbol index. do.

[0211] For example, μ PDCCH = 3 (i.e., 120 kHz SCS), and μ PDSCH =6 (i.e. In other words, when the SCS is 960 kHz, the PD When CCH is received, the position corresponding to K0=0 is 960k (kHz) slot 0. (In Figure 6, the numbers in the slots are slot indexes. means.)

[0212] If the PDCCH is received at symbol 0 of slot 0, then N pdsch Forced by ( Due to the constraints, the UE will start PD from 960k slot 8 (or 7). In this case, a value of K0 smaller than 8 (or 7) is used to set K s It was decided When PDCCH is received in the slot, the UE does not expect to receive PDSCH in that slot. If it is received at symbol 13 of bit 0, N pdsch Due to the enforcement of the UE, Since PDSCH reception is expected from 60k slot 15 (or 14), 15 (or 14) Slot K determined using the smaller K value s Do not expect to receive PDSCH.

[0213] In this way, in order to exclude values ​​of K0 for which PDSCH reception is not actually expected, The K0 value is determined by the following formula: The K0 value that can be set in is denoted as K0`.)

Also, 1.2 The methods 1.2-(1) and 1.2-(2) are set using different c values, and then 1.2 -(1) and 1.2-(2) may be operated so that the K0 setting is switched. At this time, the switch flag is indicated by the DCI.

[0228] 1.3. Determine the range of K1 values ​​according to the range of K0 values, or How to determine the range of K0 values

[0229] PDSCH is scheduled by DL grant, and H for the PDSCH is In the process of transmitting ARQ-ACK on PUCCH and / or PUSCH, The base station determines K0 (i.e., the slot in which the PDCCH is to be received) and the scheduling K1 (i.e., the interval between the slots for receiving the PDSCH) and K2 (i.e., the interval between the slots for receiving the PDSCH) The interval between the slot in which the HARQ-ACK is transmitted and the slot in which the HARQ-ACK is transmitted is set to In conventional communication systems (i.e., NR Rel-15), the K0 value is Supported values ​​are 0 to 32, and K1 supports values ​​0 to 15.

[0230] UL slot in which the terminal transmits PUCCH and / or PUSCH including HARQ-ACK. There may be situations where the network is semi-statically configured. For example, Figure 8 shows the TDD configuration. Specifically, DL slot or special An example is shown where the ratio of slots to UL slots is assumed to be 8:2. 120kHz SCS are aligned with the DL / special slots and UL slots of the TDD configuration of the configured cell. TDD settings for 480kHz SCS cells and 960kHz SCS cells is set.

[0231] For convenience of explanation, the 64 DL slots of a cell with 960 kHz SCS are The index is expressed as 0, 1, ..., 63 from the left. PDCCH scheduling PDSCH when both CSs are 960 kHz is received in slot 0, the first symbol of the PDSCH is 32. Also, the PDSCH receiving slot (or multi-slot PD The range of the offset K1 from the last slot (if SCH) to the UL slot (0 to 1 5), when considering the PDSCH reception slot (or multi-slot PDSCH The last slot of the Therefore, the PDSCH schedule is calculated in this situation using the current K0 and K1 values. In order to perform ringing, the multi-slot area where the PDSCH is located must be That is, the interval between the first slot and the last slot must be 16 or more. To configure long multi-slot PDSCH scheduling, K0 and / or K1 Furthermore, in such a situation, the range of values ​​of K0 and K1 must be increased. In the situation where the UL slot position is determined, the PDC When CH is received, if K0 is set to a large value, K1 is set to a relatively small value. If K0 is set to a small value, K1 is set to match the position of the UL slot. To set the value, K1 is set to a relatively large value.

[0232] In general, if the UL slot position is determined semi-statically, the DL grant PDCCH Depending on the position of the receiving slot, the range of values ​​for K0 and / or K1 may need to be increased. Also, a method in which the combination of K0 and K1 values ​​is determined within an appropriate range is conceivable. The use of a range of K0 and / or K1 values ​​allows for flexibility in multi-slot PDSCH scheduling. It is also useful in terms of flexibility. In 1.3 below, the range of K0 values ​​is The method for determining the range of K1 value and the method for determining the range of K0 value according to the range of K1 value are also described. This explains how to do this.

[0233] 1.3.1. Different interpretations of the K1 range depending on the K0 range

[0234] The base station uses configurable PDSCH and HARQ-ACK scheduling. The terminal specifies K0 and K1. The terminal divides the specified K0 value into N sections and calculates the K0 value for each section. The offset value to be added to the K1 value is determined according to the range as shown in Table 12.

[0235] [Table 12]

[0236] Once the offset to be added to K1 has been determined, the terminal shall apply the offset to the indicated K1 value. In addition, the UL slot in which the corresponding HARQ-ACK is transmitted is determined from the last slot of the received PDSCH. Determine the slot offset to the HARQ-ACK transmission slot (i.e., (determine the position of the

[0237] In a specific example, K0=[0, 1, ..., 32] is divided into N=3 intervals. Set a=0, b=10, c=20, d=30, F_a=8, F_b=4, F_c=2 When the base station instructs the terminal to set K0=9, the terminal receives K1+8 (=K1+F_a). From the last slot of the received PDSCH to the UL slot where the corresponding HARQ-ACK is transmitted Determine the slot interval and the UL slot position for transmitting HARQ-ACK. .

[0238] 1.3.2. Different interpretations of the K0 range depending on the K1 range

[0239] The base station uses configurable PDSCH and HARQ-ACK scheduling. The terminal is instructed to use K0 and K1. The terminal divides the specified K1 value into M parts and calculates the The offset value to be added to the K0 value is determined according to the range as shown in Table 13.

[0240] [Table 13]

[0241] Once the offset to be added to K0 has been determined, the terminal shall apply the offset to the indicated K0 value. In addition, the slot offset from the PDCCH reception slot to the PDSCH reception slot is determined. (That is, the terminal determines the position of the PDSCH reception slot.)

[0242] In a specific example, K1=[0, 1, ..., 15] is divided into intervals of M=2. The settings are e=0, f=8, g=15, F_e=8, and F_f=4. If K1=9 is specified, K0+4 (=K0+F_f) is set as the PDCCH reception slot. The slot interval from the PDSCH reception to the PDSCH reception is determined as the slot interval. Determine.

[0243] In the above method, the configurable K0 values ​​are divided into N groups in order of size. , a different offset is preset for each group, and the settable value of the conventional K1 is The value to which the offset is added is instructed to the terminal as the new K1. 1. Divide the value into M groups in order of size, and then assign different offsets to each group. After setting the value in advance, the value that can be set in the conventional K0 plus the corresponding offset is set to the terminal. It is designated as the new K0.

[0244] 1.4. How to change the range of K2 values ​​to match the range of N2 values

Also, if the UE reports CSI without TB by DCI, When configured to transmit on PUSCH, the TDRA field value m and R reportSlotOffset in RC parameter CSI-ReportConfig ListDCI-0-2, reportSlotOffsetListDCI-0-1, or Y given in reportSlotOffsetList j Using the formula: K2=maxY j (m+1) j is determined. On the other hand, the time it takes to transmit PUSCH after receiving UL grant DCI is The terminal reports to the base station, and N2 used at this time is expressed in symbol units. Determine the K2 value so that it is equal to or greater than the corresponding absolute time after the N2 value is reported, In this case, depending on the range of N2 values ​​in a specific situation, Among the supported K2 values, there may be some values ​​that are not valid. For example, if N2>14, If K2=0 or 1, the UE is not obligated to transmit PUSCH. A large SCS (e.g., 480, 960 kHz) is used to schedule multiple PUSCHs. In certain circumstances, such as when the processing time of the DCI to be A value larger than the K2 value currently supported is required. In this case, K2 can be calculated using the following method. It is decided.

[0246] 1.4-(1) K2 = ceil(N1 / c) + K2 that can be supported by RRC parameters, etc. value"

[0247] 1.4-(2) K2 = floor(N1 / c) + K that can be supported by RRC parameters, etc. 2 values

[0248] In equations 1.4-(1) and 1.4-(2), c is a semi-static value in RRC, MAC CE, etc. It is set automatically or dynamically by the DCI. The default c value is , the number of symbols per slot is 14. Methods 1.4-(1) and 1.4-(2) are used. may be configured to operate only at a specific SCS (e.g., 480, 960 kHz). Also, methods 1.4-(1) and 1.4-(2) are only applicable when N2 is greater than a certain value. Also, 1.4-(1) and 1.4-(2) are mutually exclusive. After being set using different c values, the K2 setting by 1.4-(1) and 1.4-(2) is switched. In this case, the switch flag is indicated by the DCI.

[0249] 1.5. Aperiodic CSI-RS Trigger Offset How to determine the ering offset value

[0250] Aperiodic CSI-RS (hereinafter referred to as A-CSI-RS) is used for aperiodic CSI-RS reporting. When set / instructed / used in, and at this time, the pneumologic μ csirs And the PDCCH pneumatology μ that triggers this pdcch If different, C The SI-RS trigger offset X (hereinafter referred to as offset X) is the RRC parameter ape riodicTriggeringOffset or aperiodicTrigger For each resource set using ingOffset-r16 At this time, the offset X is set as a non-periodic NZP (non-zero power ) The sequence in which DCI (or PDCCH) that triggers the CSI-RS resource is transmitted / received. The slot offset between the slot and the slot in which the corresponding CSI-RS is transmitted and / or received. The offset X that can be supported is μ csirs and μ pdcch According to the relationship , as follows:

[0251] - μ pdcch <μ csirs : offset X=[0, 1, ..., 31]

[0252] - μ pdcch >μ csirs : offsetX=[0, 1, 2, 3, 4, 5, 6, ..., 15 , 16, 24]

[0253] Using offset X, aperiodic CSI-RS is transmitted according to Table 14 below. Position of the slot K s is determined.

[0254] [Table 14]

[0255] The value of the offset X mentioned above is set to 480 kHz or 960 kHz for a short slot interval ( This is a value set without considering the slot duration, and 480 / 960kHz If used, the supported range of offset X values ​​must be increased. For example, X=16, which means the same time as 16 slots at 120 kHz (absolute time The number of slots at 960 kHz corresponding to me is 128, and to support this, The offset X value range is increased.

[0256] (1.5-1) The configurable value of offset X may be increased. Meter aperiodicTriggeringOffset or aperiodicT New configurable values ​​for triggeringOffset-r16 are available for SCS (e.g. , 480 kHz and / or 960 kHz) are newly defined. In contrast, in this embodiment, a value obtained by multiplying the conventional offset X by M is determined as the maximum value that can be supported. For example, if M=8, the offset X is set to [0, 1, ..., 31*8]. Alternatively, the offset X is set to [0, 1*8, 2*8, ..., 31*8]. M may be predefined or semi-statically determined, e.g., 480 kHz or 960 kHz. Align the timeline of the cell with 120kHz set to the timeline of the cell with 120kHz set to To achieve this, M is determined to be 4 at 480 kHz or 8 at 960 kHz. However, this is not limited to this.

[0257] (1.5-2) Add offset Y to offset X to set a new offset value When the conventional X value is X', it is determined that X = X' + Y. By way of example, the Y value may be determined according to any one of the following methods: Not limited to.

For example, the SCS with the maximum Y or W is used as the reference. The Y and / or W of the rule are determined.

[0266] The range of the offset X value is determined according to the methods (1.5-1) and (1.5-2) described above. The base station then notifies the terminal of the range of the offset X value by higher layer signaling such as RRC. Alternatively, by mutual agreement between the base station and the terminal, the conventional offset The base station sets and / or modifies the value of offset X via RRC etc. without changing the value of offset X. If specified, the terminal will define (increase) the method (1.5-1), (1.5-2), etc. There is also a way to interpret it as a value and act accordingly.

[0267] 1.6 N csirs and a method for determining the offset of K2 using Z and Z'

[0268] The CSI calculation time (computation time) defined in 3GPP TS 38.214 DCI triggers the CSI report to be sent on the PUSCH according to the and the timing between the associated CSI-RS or CSI-IM signal and the corresponding PUSCH. The timelines have the relationships shown in Table 15.

[0269] [Table 15]

[0270] In addition, HARQ-ACK and UL-SCH (or , whether the transport block is multiplexed or not Depending on the type of CSI reporting, the UE may ignore DCIs that trigger CSI reporting, as shown in Table 16. e) may be used.

[0271] [Table 16]

[0272] For the above operation, in the DCI that triggers the CSI report on the PUSCH, When setting / instructing the transmission slot of the corresponding PUSCH (for example, PDCCH and (When setting / indicating the slot offset k2 from the scheduled UL transmission), The range of supported K2 values ​​needs to be readjusted. For example, the conventional K2 is and can point to values ​​in [0,...,31], but Z and / or Z' (or Z ref Reach and / or Z' ref If the (n) value is large, a small K2 (e.g., K2 = 0) is not necessary. In this case, the CSI reporting on the PUSCH indicated by the DCI is not performed. Or the maximum value of K2 needs to be larger than the conventional 31. For kHz, if Z and / or Z' are defined as very large values, K2 will therefore To deal with this, in 1.6, Z, Z ' and / or X (offset X of 1.5) to determine a new range of conventional k2 values The method will be described below. The base station and the terminal determine a new range of K2 values. This is transmitted / set / instructed by RRC, etc. Alternatively, the base station may use the conventional K2 value as is. The terminal then transmits K2 to the terminal, and the terminal then transmits DCI (or PDC The slot offset between CH and UL slots is interpreted and applied differently. You can also perform the work.

[0273] When the previous K2 value is set to K2_old, the slot offset to be added to the previous K2 value Let K2_offset be the K2 value determined by the added offset and let K2_new be the K2 value determined by the added offset. When using K2, the range of K2 values ​​is set as follows: K2_new=K2_old+K2_offset. At this time, K2_offset is determined by one of the following methods: is determined.

[0274] - k2_offset=ceil(z / c1)

[0275] - k2_offset=floor(z / c2)

[0276] - k2_offset=X+ceil(z' / c3)

[0277] - k2_offset=X+floor(z' / c4)

[0278] In this case, c1, c2, c3, and c4 are either predefined or determined by RRC, MAC CE, etc. It can be configured semi-statically by the DCI or dynamically by the DCI. As the four values, for example, 14, which is the number of symbols per slot, is used, but this is not the only option. X means the aperiodic CSI-RS trigger offset value, which is 1.5 in the present invention. Including the offset X described.

[0280] How to calculate k2_new and k2_offset, and / or how to use Z, Z', and X The way to redefine or reinterpret k2 in this case is to use HARQ on the PUSCH where the CSI report is transmitted. - If ACK and / or UL-SCH (or transmission block) are not multiplexed This may be applied only in certain cases.

[0282] How to calculate k2_new and k2_offset, and / or how to use Z, Z', and X The way k2 is redefined or reinterpreted in this context is to allow for a single DCI-triggered CSI report. It may be applied only if the number of CSI reports triggered is less than 1, regardless of the number of CSI reports triggered. This may also be done.

[0283] 7) Delay requirements for aperiodic CSI reporting How to determine the irement

[0284] In conventional NR systems, the frequency ranges FR1 or FR2-1 (below 52.6 GHz) For each pneumologic (or SCS) category, use Tables 17 and 18 to determine the CSI content. The CSI reporting latency is specified for each CSI. The reports (i.e., each CSI reporting configuration) are classified into three latency classes: s), and for each class, Z1 (low-latency c class), Z2 (high-latency class), Z3 (other cases) are the delay requirements. It also applies to requirements that are lower than low-latency. For Ultra Low-latency, Table 17 is defined.

[0285] Table 17 is based on Table 5.4-1: CSI computation in 3GPP 38.214. ation delay requirement 1, and Table 18 is based on 3GPP 38. Table 5.4-2: CSI computation delay requirement irement 2.

[0286] [Table 17]

[0287] [Table 18]

[0288] For example, in Table 18, Z1 and Z1' are CSI reports that simultaneously meet the following three conditions: This applies to all notices.

[0289] - Wideband frequency-granularity

[0290] - A single CSI-RS resource (ie, no CRI rep orting) with at most 4 CSI-RS ports

[0291] - PMI reporting with Type I Single-Panel Codebook or non-PMI reporting

[0292] Z3 and Z3' are used for L1-RSRP reporting (i.e., beam management). Z2 and Z2' are for reporting other CSI content. The applicable delay requirements are:

[0293] Table 17 also shows the lowest latency (Ultra-low latency) This is a requirement for low-latency class CSI. When a report is triggered (i.e., Z1 and Z1' in Table 5.4-2 are applied) In certain conditions (e.g., all CPUs of the UE are unoccupied) The PUSCH to which the CSI report is transmitted is in the UL-SCH or is applied if HARQ-ACK is not multiplexed) This is a delay requirement. TS 38.214 defines it as shown in Table 19. do.

[0294] [Table 19]

[0295] Used in the FR2-2 (52.6 to 71 GHz) or high frequency (52.6 GHz or higher) band. For the SCS used (e.g., 480 kHz or 960 kHz), the most No latency requirements are set for ultra-low latency. If not, then a provision for reporting time requirements for that single CSI will be required.

[0296] Proposed method 1.7-1

[0297] SCS (e.g., 480 kHz) used in high frequency bands (e.g., 52.6 GHz and above) z and / or 960 kHz or higher SCS) there is one delay requirement When only the lowest latency class is defined (i.e., Ultra latency class) s) separately defined delay requirements), the relevant CSI report shall UL-SCH or HARQ-ACK is multiplexed onto the PUSCH on which the notification is sent. Whether or not the CP in use by the UE at the time of CSI reporting (or CSI-RS reception) A single delay requirement is followed regardless of the number of U (CSI Processing units). An example of this is the low latency class. For Report 1 and Report 2, which have the same CSI report settings, Report 1 is HARQ-A. CK and transmitted to a specific PUSCH, and report 2 is multiplexed with Even if the PUSCH is transmitted to another specific PUSCH without any synchronization, the delay requirements for Report 1 and Report 2 are the same. In another embodiment, the same CSI reporting corresponding to the low delay class is set. For report1 for UE1 and report2 for UE2, indicates that all CPUs are unoccupied (unoccupied) at the time of the corresponding CSI trigger (or CSI-RS reception). Received) state, and UE2 receives the corresponding CSI trigger (or CSI-RS reception) Even if some CPUs are occupied at the time, report1 for The delay requirements for UE1 and report2 for UE2 apply equally.

[0298] Proposed method 1.7-2

[0299] SCS (e.g., 480 kHz) used in high frequency bands (e.g., 52.6 GHz and above) z and / or 960 kHz or higher SCS) there is one delay requirement When only the lowest latency class is defined (i.e., Ultra latency class) If the delay requirement for s) is not separately defined, the following three conditions are met: The UE does not expect CSI reporting configuration.

[0300] - Wideband frequency-granularity

[0301] - A single CSI-RS resource (ie, no CRI rep orting) with at most 4 CSI-RS ports

[0302] - PMI reporting with Type I Single-Panel Codebook or non-PMI reporting

[0303] Specifically, the UE selects the CSI reporting configuration when these three conditions are met simultaneously. t setting) and meets some (or any) of these three conditions. It is also possible to not expect any CSI reporting settings to be configured.

[0304] Also, more generally, SCS ( For example, for 480 kHz and / or 960 kHz or higher SCS, The UE shall not expect any CSI reporting configuration that satisfies all or any of these three conditions. It can be made.

[0305] 1.8. How to apply the delay requirement for aperiodic CSI reporting

[0306] C for 480 kHz and / or 960 kHz SCS in the FR2-2 band The SI computation delay requirement is , TS 38.214 Table 5.4-2 computation delay r This defines a new CSI calculation delay requirement. Table 5.4-2 of 3GPP TS 38.214, which defines May be changed. Table 17 is used without modification.

[0307] [Table 20]

[0308] In this case, the μ value is min(μ PDCCH , μ CSI-RS , μ UL ) is defined as 3GPP TS Refer to 5.4 of 38.214, "μ of table 5.4-1 and t able 5.4-2 corresponds to the min (μ PDCCH , μ CSI-RS , μ UL ) where the μ PDCCH corresponds to t he subcarrier spacing of the PDCCH with which the DCI was transmitted and μ UL cor responds to the subcarrier spacing of th e PUSCH with which the CSI report is to be transmitted and μ CSI-RS corresponds to t he minimum subcarrier spacing of the ape "CSI-RS triggered by the DCI" is displayed. There are.

[0309] That is, the minimum value of μ of PDCCH, CSI-RS, and PUSCH is used as a reference. The CSI calculation delay requirement is determined, but μ PDCCH , μ CSI-RS , μ UL Among them, μ=5 or Mixed pneumologic cases where μ=6 and smaller values ​​(e.g., μ=4) are mixed For any CSI computation delay requirement for mixed numerology cases, A rule is needed to determine which term applies.

[0310] In this invention, the application method of the CSI calculation delay requirement will be explained in the following three cases.

[0311] - μ PDCCH , μ CSI-RS , μ UL If both values ​​are 5 or greater

[0312] - μ PDCCH , μ CSI-RS , μ UL If any one of the values ​​is 5 or greater

[0313] - μ CSI-RS If the value is 5 or greater

[0314] More specifically, the UE and / or the network (or gNB) may: -1), (1.8-2a), (1.8-2b), (1.8-2c), (1.8-3a) and / or (1. 8-3b) and operate in accordance with one or more of the UE and / or the network. It operates according to a combined method.

[0315] Method (1.8-1)

[0316] min(μ PDCCH , μ CSI-RS , μ UL )=5 or min(μ PDCCH , μ CSI-RS , μ UL )=6 If so, use Table 20. Z1 (and Z1'), Z2 (and Z2'), Z3 (and Z3') Which value to apply depends on the triggered CSI, similar to the operation of conventional communication systems. In particular, the CSI report to which Z1 (and Z1') applies is When triggered, there is no CPU occupied and no HARQ-ACK or data In the situation where data is not multiplexed (i.e., in Rel-15 / 16) This is the case where the Z1 and Z1' delay requirements of Table 17 described in 1.7 are applied. Even if the conditions are met), the Z1 and Z1' values ​​in Table 20 are used as the CSI calculation delay requirements. Used.

[0317] Method (1.8-2a)

[0318] μ PDCCH , μ CSI-RS , μ UL If at least one of the items is 5 or 6, Table 20 Therefore, μ PDCCH , μ CSI-RS , μ UL At least one of the following must be 5 or more. If a morphology is present, Table 17 is not used. For example, μ PDCCH = 3, μ C SI-RS = 3, μ UL = 5, the values ​​defined in Table 20 are the CSI calculation delay requirements. In this case, μ PDCCH = 3 is the minimum value, so it corresponds to μ = 3 in Table 20 One of Z1 (and Z1'), Z2 (and Z2'), and Z3 (and Z3') is triggered. Used depending on the type of CSI report. In particular, CSI reports to which Z1 (and Z1') is applied When triggered, there is no CPU occupied and PUSCH is not receiving HARQ-ACK or The situation where data (transmission blocks) are not multiplexed (i.e., Rel-15 This is the case where Z1 and Z1' delay requirements in table 5.4-1 are applied in / 16. (This corresponds to the conditions for using table 5.4-1 explained in 1.7) 1. The Z1' value is used as the CSI calculation delay requirement.

[0319] Method (1.8-2b)

[0320] μ PDCCH , μ UL , for aperiodic CSI-RS triggered by PDCCH (DCI) If at least one of the pneumology categories is 5 or 6, Table 20 is used. For example, μ PDCCH If μ = 5, CSI-RS and μ UL CSI calculation regardless of value Table 20 is used as the delay requirement. PDCCH = 3, μ UL =3 and multiple messages for two aperiodic CSI-RS triggered by the corresponding PDCCH. -If each of the mallogies is μ = 3, μ = 5, then min(μ PDCCH , μ CSI-RS , μ UL )=3, but the PDCCH Since the CSI-RS with the BER performance is configured, Table 20 is used as the CSI calculation delay requirement. do.

[0321] Method (1.8-2c)

[0322] μ PDCCH , μ CSI-RS , μ UL If at least one of the μ values ​​is 3 or less, see Table 1 7 or Table 20 is used. The delay applied depending on the type of CSI report triggered is , Z1 (and Z1'), Z2 (and Z2'), Z3 (and Z3'). When the CSI report is triggered, the conditions (i.e., Z1 and Z1') apply. There is no CPU involved, and HARQ-ACK and data are multiplexed onto the PUSCH. In situations where the This is a case where the Z1' delay requirement is applied, and it corresponds to the conditions for using Table 17 explained in 1.7. In this case, one of Tables 17 and 20 is selected and applied.

[0323] Method (1.8-3a)

[0324] μ CSI-RS If the value is 5 or 6, then Table 20 is used. PDCCH and / or is μ UL Regardless of the value of μ CSI-RS If the value is 5 or greater, then Table 20 is used. For example: , μ CSI-RS= 6, Table 20 is used. In particular, Z1 (and Z1') applies When a CSI report is triggered, there is no CPU occupied and HARQ is not available for PUSCH. -Situations where ACK and data are not multiplexed (i.e., Rel-15 / 1 6, this is the case where the Z1 and Z1' delay requirements in table 5.4-1 are applied. Even if the conditions for using Table 17 described in 1.7 are met, the Z1 and Z1' values ​​in Table 20 are Used as SI calculation delay requirement.

[0325] Method (1.8-3b)

[0326] Pneumothorax of PDCCH (DCI) triggered aperiodic CSI-RS If at least one is 5 or 6, then Table 20 is used. PDCCH and / or μ UL and / or μ CSI-RS Regardless of the value, the PDCCH-triggered aperiodic C If at least one of the pneumology items in the SI-RS is 5 or higher, see Table 20. In particular, when a CSI report to which Z1 (and Z1') is applied is triggered, There is no occupied CPU, and HARQ-ACK and data are multiplexed onto the PUSCH. In situations where the This is the case where Z1 and Z1' delay requirements are applied, and the conditions using Table 17 explained in 1.7 are used. Even in cases where the Z1 and Z1' values ​​in Table 20 are used as the CSI calculation delay requirements, can be.

[0327] 1.9. CPU occupancy for aperiodic CSI reporting

[0328] TS 38.214 5.2.1.6 (CSI processing criteria) In this case, when aperiodic CSI reporting is triggered, the CSI reporting is processed in the UE. For the CPU (CSI processing unit) used / occupied for processing, The rules are defined as shown in Table 21.

[0329] [Table 21]

[0330] According to Table 21, certain situations and / or certain CSI reporting settings When triggered, the UE will operate to use / occupy all available CPUs. The situation corresponds to the conditions for using Table 17 explained in 1.7, but the CSI is not triggered. If there is no CPU occupied at the time of the CSI report and the PUSCH on which the CSI report is transmitted is not The situation where RQ-ACK or data (=transmission block) is not multiplexed In addition, a specific CSI reporting setting is one that satisfies the conditions for using Table 17, as explained in 1.7. However, “the CSI corresponds to a single CSI with wideband frequency-granularity and to at most 4 CSI-RS ports in a single re source without CRI report and where code bookType is set to 'typeI-SinglePanel' o r where reportQuantity is set to 'cri-RI In this way, in a particular situation / setting, the UE By operating in such a way that it uses / occupies all CPU resources, the short processing delays in Table 17 are met. In other words, there are certain situations where a short processing delay is applied, as in Table 17. and all CPU resources of the UE are used and / or dedicated only for a specific CSI reporting configuration.

[0331] On the other hand, for 480kHz and / or 960kHz SCS (as mentioned above) Only computation delay requirement 2 is defined and applied. i.e., CSI c for 480 kHz and / or 960 kHz SCS Since computation delay requirement1 is not defined, For CSI reports where the corresponding SCS / pneumology is set, the UE In other words, there is no need to use / occupy CSI c to process the CSI report. Computation delay requirement 2 (meaning a relatively long time compared to Item 1) Using / occupying the entire CPU for this purpose results in inefficient CPU usage, Aperiodic triggers during this time because all CPUs are used / occupied CSI reports may not be updated at all.

[0332] If Table 17 is not used for the CSI calculation delay requirement, The UE behavior needs to be changed so that U is not used / occupied.

[0333] Section 1.9 explains how to apply the CSI computation delay requirement in the following three sections:

[0334] - μ PDCCH, μ CSI-RS , μ UL If both values ​​are 5 or greater

[0335] - μ PDCCH , μ CSI-RS , μ UL If any one of the values ​​is 5 or greater

[0336] - μ CSI-RS If the value is 5 or greater

[0337] More specifically, the UE and / or the network (or gNB) may: -1), (1.9-2) and / or (1.9-3). The work may operate in one or a combination of two or more of these ways, or Even in this case, Table 17 is defined / used for the CSI calculation delay requirements for aperiodic CSI reporting. If not used / applied, the UE will use / occupy all CPU instead of setting to a portion of the available CPUs (e.g., CPU =K s , where K s is the n number of CSI-RS resources in the CSI-RS resource set for channel measurement) Acts as if used / occupied.

[0338] Method (1.9-1)

[0339] min(μ PDCCH , μ CSI-RS , μ UL )=5 or min(μ PDCCH , μ CSI-RS , μ UL )=6 In some cases, Table 20 is used / applied for the computational delay requirements of the applicable CSI reports, and Table 17 is Not used / applied. In this case, the UE will use / occupy all CPUs. Instead, use a portion of the available CPU (e.g., CPU =K s , where K s is th e number of CSI-RS resources in the CSI- RS resource set for channel measurement) Therefore, the rules in Table 21 are as follows: For example, the table will be amended as shown in Table 22 or Table 23. Not limited to.

Alternatively, this condition may be applied to μ CSI-RS Pseudo-CSI-RS triggered by PDCCH (DCI) instead of The UE is configured to use / occupy all CPUs. Instead, it operates to use and / or occupy only a portion of the available CPU. Ba, O CPU =K s It becomes. K s is the CSI-RS resource set for channel measurement the number of CSI-RS resources rces in the CSI-RS resource set for chan This means that the rules in Table 21 are 2) will be revised appropriately to reflect the above. For example, it will be revised as shown in Table 24 or Table 25. This is not limited to the above.

The conditions are the same as in Method (1.8-3b), μ CSI-RS Trigger on PDCCH (DCI) instead of The UE is substituted with one of the supported aperiodic CSI-RS neurologies. Instead of being set to use / occupy all CPUs, it will only use a portion of the available CPUs. For example, O CPU =K s It becomes. K s Ha, Chan is the number of CSI-RS resources in the CSI-RS resource set for channel measurements. Accordingly, the rules in Table 21 are amended accordingly to reflect Method (1.9-2). For example, Table 26 or Table 27, but is not limited to this.

[0350] 1.10. Extra PDSCH processing time sing time)

[0351] As per 5.3 of 3GPP TS 38.214 (see Table 28), the last synch of the PDSCH The first symbol of the PUCCH in which the HARQ-ACK for the corresponding PDSCH is transmitted from the The distance to the proc,1 If the guarantee is greater than the valid HARQ -Provide ACK.

[0352] [Table 28] JPEG2026004534000044.jpg225163

[0353] At this time, d 1,1 If the number of symbols in each PDSCH is less than a certain number, PD The extra processing time (extra p) added to allow for SCH processing time processing time), and d2 is the higher priority index. The PUCCH with a larger priority index is the one with a smaller priority. PUCCH / P with smaller priority index Extra processing time when overlapping with USCH This can be understood as processing time.

[0354] On the other hand, in the FR2-2 band, for 480 kHz and / or 960 kHz SCS The N1 value for 480 kHz will be newly defined. The value is the N1 value for 120kHz SCS multiplied by X1, and the N1 value for 960kHz The value is X2 times the N1 value for 120kHz SCS. To ensure the same absolute time as the processing time, use X1=4 and X2=8. As shown above, the N1 values ​​for 480kHz and 960kHz are respectively It may be defined as four or eight times the N1 value.

[0355] At this time, T proc,1 When calculating N1, d 1,1 , d2 are added at the same rate, Therefore, the scale between them must be the same. In other words, for a particular SCS, If the newly defined N1 value is scaled by X times compared to the previous value, then d 1,1 and / or d2 also needs to be scaled by a factor of X. For example, d 1,1 = 1 In this case, as shown in Table 9, N1 for 120 kHz is 20 symbols, so d 1,1 =1 is N 5% extra processing time compared to 1 However, since N1 for 960 kHz is 160 symbols, d 1,1 =1 The extra processing time (extra processing time) is 0.6% compared to N1. ime) effect can be expected. d in kHz 1,1 Adding this can be expected to increase processing time by approximately 30%. However, at 960kHz, the effect of an increase in processing time of only about 3.75% can be expected. Therefore, d 1,1 It is necessary to scale it by the same ratio as N1. , d2 also needs to be scaled.

[0356] (Method 1.10-1)

[0357] T proc,1 When calculating, for 480kHz SCS, d 1,1 and / or d2 Scaling by 4 times, for 960kHz SCS, d 1,1 and / or d2 multiplied by 8 Scaled and used. d 1,1 and / or the respective scaling methods for d2, Follow the examples below and the description that follows.

[0358] (Example 1.10-1-1): Conventional Rel-15 / 16 for 480 kHz SCS d defined as 1,1 and / or the rules for d2 are changed as per Table 29.

[0359] [Table 29]

[0360] At this time, d 1,1and / or the method for determining the d2 value is the same as that in Example 1.10-1-1. For example, the PDSCH mapping type (m For mapping type A, d1,1 = 4 * (7-i) and d1,1 = 4*7-i, and d2 may be calculated by scaling the value reported by the UE. It may be used as is, or it may be scaled by a factor of 4 or expressed in other formats. For PDSCH mapping type B, when L >= 4 and L <= 6, d1 , 1 = 4 * (7 - L) or d1, 1 = 4 * 7 - L. At some point, you can calculate d1,1=4*(3+min(d,1)), and d1,1=4*3+mi You can also calculate n(d,1) or d1,1=3+4*min(d,1). When L=2, You can calculate d1,1=4*(3+d), but d1,1=4*3+d or d1,1=3+ It can also be calculated as 4*d.

[0361] (Example 10.1-1-2): Conventional Rel-15 / for 960 kHz SCS d as defined in 16 1,1 and / or the rules for d2 are changed as per Table 30.

[0362] [Table 30]

[0363] In this case, the method for determining the d1, 1 and / or d2 values ​​is the same as that in Example 10.1-1-2. For example, in the case of PDSCH mapping type A, On the other hand, d1,1=8*(7-i) may be calculated, or d1,1=8*7-i may be calculated. Also, d2 may use the value reported by the UE without scaling it. , may be scaled by a factor of 8 or expressed in other formats. PDSCH Mapping Type B For L>=4 and L<=6, d1,1=8*(7-L) may be calculated. , d1,1=8*7-L. When L=3, d1,1=8*(3+min( d,1)) may be calculated as d1,1=8*3+min(d,1) or d1,1=3+8*mi You can also calculate it as n(d, 1). When L=2, you can also calculate it as d1, 1=8*(3+d). Alternatively, it may be calculated as d1,1=8*3+d or d1,1=3+8*d.

[0364] (Method 1.10-2)

[0365] T proc,1 When calculating, for 480kHz SCS, d 1,1 is X1 times, d2 is X Scaling by 2, for 960kHz SCS, d 1,1 is multiplied by Y1, and d2 is multiplied by Y2 X1, X2, Y1, Y2 are predefined for each SCS. , set by higher layer signaling such as RRC or DCI indication (indication tion) etc. 1,1 and / or d2, respectively, are scaled as follows: Follow the examples below and the description that follows.

[0366] (Example 1.10.2-1): Conventional Rel-15 / 1 for 480 kHz SCS d as defined in 6 1,1 and / or the rules for d2 are changed as per Table 31.

[0367] [Table 31]

[0368] At this time, d 1,1 and / or the method for determining the d2 value is the same as that in Example 1.10-2-1. For example, in the case of PDSCH mapping type A, In contrast, d 1,1 =X1*(7-i) 1,1 You can also calculate it as =X1*7-i Also, d2 may use the value reported by the UE without scaling it. Alternatively, it may be scaled by a factor of X2 or expressed in other formats. For type B, when L>=4 and L<=6, d 1,1 Calculate =X1*(7-L) Well, d 1,1 =X1*7-L. When L=3, d 1,1 =X1*(3+ min(d,1)) and d 1,1 =X1*3+min(d,1) or d 1,1 =3+X You can also calculate it as 1*min(d,1). When L=2, d 1,1 Calculate =X1*(3+d) You may do so, d 1,1 =X1*3+d or d 1,1 It can also be calculated as =3+X1*d.

[0369] (Example 1.10-2-2): Conventional Rel-15 / for 960 kHz SCS d as defined in 16 1,1 and / or the rules for d2 are changed as per Table 32.

[0370] [Table 32]

[0371] At this time, d1,1 The method for determining the d2 value is not limited to the method in Example 2. For example, for PDSCH mapping type A, d 1,1 = Y1 * (7-i) 1,1 = Y1*7-i. Also, d2 is The UE may use the reported value without scaling or may scale it by a factor of Y2. It may be scaled or expressed in other formats. For PDSCH mapping type B When L>=4 and L<=6, d 1,1 = Y1 * (7-L) 1,1 = Y1*7-L. When L=3, d 1,1 =Y1*(3+min(d,1) ) and d 1,1 =Y1*3+min(d,1) or d 1,1 =3+Y1*min(d, 1) can be calculated as follows. When L=2, d 1,1 You can also calculate it as =Y1*(3+d), and d1 ,1 =Y1*3+d or d 1,1 It can also be calculated as =3+Y1*d.

[0372] Furthermore, T for 480kHz or 960kHz SCS proc,1 When calculating T ext The values ​​may also be scaled, e.g., depending on the specific situation (or if certain conditions are met). (if applicable), T ext will be a non-zero value, but is the T for 960kHz SCS proc,1 When calculating, do not use this value as it is. , the scaled value is used. At this time, the scaling is 1,1 , for d2 As with the proposed method, multiply by 4 for 480 kHz and by 8 for 960 kHz, or The value is set to a defined value or an RRC setting value.

[0373] The aforementioned T proc,1 d for calculation 1,1 and / or d2 and / or T ext Scaling the values The method of using it is proc,1 Apply all or only part of the calculation. For example, d 1,1 is scaled by a factor of 4 or 8 by the SCS, and T proc,1 calculation formula and other d2 or Text are applied to the formula as is.

[0374] The aforementioned d 1,1 and / or d2 and / or T ext How to scale and use values , can be applied regardless of the PDSCH scheduling method. For example, This also applies when there is one PDSCH scheduled in the DCI. The same applies when scheduling multiple PDSCHs on a CI.

[0375] 1.11. Extra PUSCH preparation time n time)

[0376] As per TS 38.214, 6.4 (see Table 33), the PUSCH for TB transmission is From the last symbol of the PDCCH to be scheduled to the first symbol of the corresponding PUSCH The interval is T proc,2 If a larger guarantee is given, the UE transmits the corresponding TB.

[0377] [Table 33] JPEG2026004534000050.jpg220168

[0378] At this time, d 2,1 is when the first symbol of each PUSCH consists of only DM-RS. If d 2,1 = 0, and DM-RS and data are multiplexed in the first symbol. If yes, d 2,1 = 1. d2 is the PUSC with the larger priority index. When H is overlapped with a PUCCH having a smaller priority index, an extra This can be understood as extra preparation time. 2,2 teeth This is considered as extra time for when BWP conversion is triggered. I can solve it.

[0379] On the other hand, in the FR2-2 band, for 480 kHz and / or 960 kHz SCS When defining the N2 value for 480 kHz, the N2 value for 120 kHz SCS is The N2 value for 960kHz is determined as X1 times the N2 value for 120kHz SCS. For example, if X1=4 and X2=8, then the following Table 3 As shown in 4, the N2 values ​​for 480kHz and 960kHz are respectively It is defined as 4 or 8 times the N2 value.

[0380] [Table 34]

[0381] At this time, T proc,2 When calculating N2, d 2,1 , d2 are added at the same rate, Therefore, if the N2 value is scaled by a factor of X for a particular SCS, then d 2,1 and / or d2 also needs to be scaled by a factor of X.

[0382] (Method 1.11-1)

[0383] T proc,2 When calculating, for 480kHz SCS, d 2,1 and / or d2 Scaling by 4 times, for 960kHz SCS, d 2,1 and / or d2 multiplied by 8 Scale and use. d 2,1 and / or d2, respectively, are as follows: Example and the following description.

[0384] (Example 1.11-1-1): For 480 kHz SCS, the first signal of PUSCH If the ball is DM-RS only, 2,1 =0, otherwise d 2,1 = 4. d2 is "If a PUSCH of a larger priority in dex would overlap with PUCCH of a smaller pr If the value is "security index", set it to four times the value reported by the UE. otherwise set to 0.

[0385] (Example 1.11-1-2): For 960 kHz SCS, the first signal of PUSCH If the ball is DM-RS only, 2,1 =0, otherwise d 2,1 = 8. d2 is "If a PUSCH of a larger priority in dex would overlap with PUCCH of a smaller pr If the value is "security index", set it to 8 times the value reported by the UE. otherwise set to 0.

[0386] (Method 1.11-2)

[0387] T proc,2 When calculating, for 480kHz SCS, d 2,1 is X1 times, d2 is Scaling by x2, for 960kHz SCS, d 2,1 is Y1 times, d2 is Y2 X1, X2, Y1, and Y2 are predefined for each SCS. It may be set by higher layer signaling such as RRC, or may be set by DCI instructions, etc. d 2,1 and / or d2 are described in the following examples and subsequent sections. Follow the instructions provided.

[0388] (Example 1.11-2-1): For 480 kHz SCS, the first signal of PUSCH If the ball is DM-RS only, 2,1 =0, otherwise d 2,1 = X1. d2 is "If a PUSCH of a larger priority i ndex would overlap with PUCCH of a smaller p If the priority index is "priority index", the value reported by the UE is multiplied by X2. otherwise set to 0.

[0389] (Example 1.11-2-2): For 960 kHz SCS, the first signal of PUSCH If the ball is DM-RS only,2,1 =0, otherwise d 2,1 = Y1. d2 is "If a PUSCH of a larger priority i ndex would overlap with PUCCH of a smaller p If the priority index is "Y", the value reported by the UE is multiplied by Y2. otherwise set to 0.

[0390] d for 480kHz and 960kHz SCS 2,2

[0391] In Rel-15 / 16, for 15kHz to 120kHz SCS, T p roc,2 used to calculate d 2,2 The BWP conversion time value defined in TS 38.133 is The values ​​are defined in Table 35. (TS 38.133, 8.2.2.5(I interruptions due to Active BWP switching re (Excerpt from the quirement)

[0392] [Table 35]

[0393] Meanwhile, the values ​​for 480 kHz and 960 kHz are further defined as shown in Table 36. do.

[0394] [Table 36]

[0395] d for 480kHz and / or 960kHz SCS 2,2 Also, as mentioned above, 2,1or d2 Like, T proc,2 In the calculation of BWP conversion time, the value is scaled and used. For example, when using the values ​​in the table above, d for 480 kHz SCS is 2,2 =4*17*0.03 125 or d 2,2 =x3*17*0.03125, and d2 for 960kHz SCS ,2 = 8*33*0.015625 or d 2,2 =Y3*33*0.015625. Alternatively, d for 480 kHz and / or 960 kHz SCS 2,2 is 12 Used as the scheduled value for the BWP transition time value for 0kHz SCS For example, d for 480 kHz SCS 2,2 = 4*5*0.03125 or d 2,2 =x4 *5*0.03125 is used to calculate the d for 960kHz SCS. 2,2 =8*5*0.015 625 or d 2,2 Use =Y4*5*0.015625. In this case, X3, X4, Y3 Y4 is either predefined for each SCS or determined by higher layer signaling such as RRC. This is set by the user or by a DCI instruction, etc.

[0396] Alternatively, d for 480 kHz and / or 960 kHz SCS 2,2 is defined for 480kHz and 960kHz SCS without scaling. You may use the BWP conversion time value provided. For example, (using the table above), 480 kHz for SCS 2,2 =17*0.03125, for 960kHz SCS d 2,2 = 33 * 0.015625 to Tproc,2 Apply during calculation.

[0397] Furthermore, T for 480kHz or 960kHz SCS proc,2 In the calculation of T ext and / or T switch The values ​​may also be scaled, e.g., depending on the specific situation (or (if certain conditions are met), T ext or T switch The value is non-zero However, the T for 480kHz or 960kHz SCS proc,2 In the calculation of In this case, do not use this value as it is, but use a scaled value. The d 2, 1, d 2, 2, as with d2, 4 times for 480kHz and 8 times for 960kHz Alternatively, it may be set to a predefined value or an RRC setting value.

[0398] The aforementioned T proc,2 For the calculation of d 2, 1, d 2, 2, d2 and / or T ext , T switch Value The method for scaling and using it is T proc,2 Apply all or part of the calculation For example, d 2,1 Scaled by 4x or 8x depending on SCS T proc,2 Apply to the formula and other d 2, 2, d2 or T ext , T switch is calculated as is Apply to Eq.

[0399] The aforementioned d 2, 1, d 2,2 and / or the method of scaling and using the d2 value is PUS It may be applied regardless of the scheduling method of the CH. For example, scheduling with one DCI This also applies to the case where there is one PUSCH to be scheduled, and multiple PUs are scheduled with one DCI. The same applies when scheduling the SCH.

[0400] 1.12. HARQ Feedback Timing Indicator fiel d in the successRAR

[0401] The 3-bit field "PDSCH-to- The "HARQ_feedback timing indicator field" value is S For CS 120kHz and below, regardless of SCS, [1, 2, 3, 4, 5, 6, 7, 8]. However, for 480 kHz and 960 kHz SCS, RAN 1♯107-e meeting (also using 3 bits) As the values ​​indicate, for 480kHz it is [7, 8, 12, 16, 20, 24, 28 , 32], and for 960 kHz [13, 16, 24, 32, 40, 48, 56, 64]. It has been decided that:

[0402] On the other hand, 38.213's 8.2A (Random access response - T Type-2 random access procedure) requires that the terminal is MsgB-R NTI CRC scrambled DCI format 1_0 After detection, when the associated PDSCH is received, the RAR message is sent. If the message is successRAR, the PUCCH slot for transmitting HARQ-ACK is The location is determined by the 3-bit field "HARQ Feedb" in the successRAR. It is stated that the value of the "ACK Timing Indicator field" is used. Table 37 is an excerpt from 8.2A of 38.213.

[0403] [Table 37] JPEG2026004534000055.jpg162167

[0404] Also, in 38.321 6.1.5a, each field of successRAR is defined. Among them, "HARQ Feedback Timing Indicator" tor is the "PDSCH-to-HARQ" for MSGB HARQ feedback It is specified as a "feedback timing indicator field." The specific values ​​are set out in 8.2A of 38.213, as excerpted above. This allows the MSGB HA to be used in the 2-step RACH procedure. The PUCCH slot position for RQ feedback is defined as n+k+Δ, where n is the slot index for receiving PDSCH, and k is the number of bits in [1, 2, 3, 4, 5, 6, 7 ,8], Δ is considered as the time margin for PUSCH transmission. Δ is defined in Table 6.1.2.1.1-5 of TS 38.214, and RA According to the N1♯107-e meeting, "Δ=24" for 480kHz, 96 For 0 kHz, a new definition of "Δ=48" is given.

[0405] In this situation, the slot position where the HARQ feedback is transmitted is determined as follows: For 480 kHz and / or 960 kHz SCS, the conventional [1, 2, 3, 4, 5 , 6, 7, 8] are used as they are, the corresponding slot position must be adjusted to match the uplink slot. In order to achieve this, the position of slot n where the PDSCH containing the RAR message is received must be determined as follows: The reason is that the SCS for 480 kHz and / or 960 kHz The lot configuration is likely to be aligned with the semi-static UL:DL configuration of the 120kHz SCS. Therefore, for example, when UL:DL=1:4, the 480kHz SCS This is because there may be no UL slot among the 16 slots (in the case of 960 kHz (32 slots in the 480 / 960 kHz band). Therefore, the above k value is also DCI 1_ 0 "PDSCH-to-HARQ_feedback timing indicator or field" value needs to be changed to have a larger value.

[0406] On the other hand, the Δ value defined for 480 / 960kHz is N1( That is, the time corresponding to the PDSCH processing time and the RAR message are sent to the upper level. Therefore, the value is determined to cover the time it takes for the sound to reach the ear. DCI 1_0 for 960kHz "PDSCH-to-HARQ_feedback The "k timing indicator field" is set to the MSGB HARQ feed If it is used as it is to determine the PUCCH slot position for back, This would result in unnecessary duplication of the N1 value.

[0407] Considering all of this, in the 2-step RACH process, the MSGB HARQ frame The k value for calculating the PUCCH slot position n+k+Δ for feedback is given by The value is one of:

[0408] - 480kHz: [7, 8, 12, 16, 20, 24, 28, 32], 960kHz :[13, 16, 24, 32, 40, 48, 56, 64]

[0409] This value is the PDSCH-to-HARQ_Feedback_Time for DCI 1_0. The timing indicator field value is identical to the N1 value, even though there is an inefficiency in adding the N1 value twice. However, it has the advantage that a consistent value can be used for 480 / 960kHz. .

[0410] - 480kHz:[1, 2, 6, 10, 14, 18, 22, 26], 960kHz:[ 1, 4, 12, 20, 28, 36, 42, 50]

[0411] This value is the first candidate value above minus the N1 equivalent time for the SCS. Specifically, it is reduced by floor(N1 / 14) (or by ceil(N1 / 14)-1). By setting the minimum value to 1, the minimum value after PDSCH reception and Δ has elapsed is Instructions can be given from the first slot.

[0412] - 480kHz:[0, 1, 5, 9, 13, 17, 21, 25], 960kHz:[0 , 3, 11, 19, 27, 35, 41, 49]

[0413] This value is the first candidate value above minus the N1 equivalent time for the SCS. Specifically, it means the value reduced by ceil(N1 / 14). The minimum value 0 is the value This is to enable instructions to be given from the last slot of the Δ period after receiving the SCH.

[0414] - 480kHz:[1, 5, 9, 13, 17, 21, 25, 29], 960kHz:[ 1, 9, 17, 25, 33, 41, 49, 57]

[0415] This value is indicated from the first slot after PDSCH reception and Δ has elapsed, and each indicated value The interval is fixed at 4 or 8. The reason for setting the interval at 4 / 8 is that the 12 This is because it is the length of one slot of the 0 kHz SCS.

[0416] - 480kHz: [4, 8, 12, 16, 20, 24, 28, 32], 960kHz :[8, 16, 24, 32, 40, 48, 56, 64]

[0417] This value is set to 4 or 8 from the last slot of the Δ period after receiving the PDSCH. is a fixed value.

[0418] - 480kHz:[1, 4, 8, 12, 16, 20, 24, 28], 960kHz:[ 1, 8, 16, 24, 32, 40, 48, 56]

[0419] This value is set to the maximum value to indicate the first slot after PDSCH reception and Δ has elapsed. The readings were reduced to 28 or 56.

[0420] - 480kHz: [1, 8, 12, 16, 20, 24, 28, 32], 960kHz :[1, 16, 24, 32, 40, 48, 56, 64]

[0421] This value is indicated from the first slot after PDSCH reception and Δ has elapsed, and is indicated to the maximum. The possible values ​​are kept to 32 or 64.

[0422] In addition, the minimum and maximum values ​​(out of 8 values) of the candidate values ​​listed above are MSGB Since the PUCCH slot for HARQ feedback falls within the possible positioning range, This is especially important for situations where fast HARQ feedback for MSGB is required. The k value is determined so as to include the minimum value "1". You can provide the quickest feedback.

[0423] Additionally, for 480 kHz and / or 960 kHz SCS, the PUCCH slot To eliminate the inefficiency of redundantly considering N1 in determining the bit position (n+k+Δ), Instead of Δ, you can use the number of slots corresponding to 0.5 msec. ec corresponds to 16 slots at 480kHz SCS and 32 slots at 960kHz. Since it corresponds to the slot, the MSGB HARQ fee is The PUCCH slot position for the feedback is n+k+ for 480 kHz SCS. For 960kHz SCS, it is decided to be n+k+32 (where n is is the PDSCH reception slot, and k is one of the seven candidate values ​​above). 0kHz (only one slot) margin, and for 480kHz SCS it is n+k For 960kHz SCS, it is determined to be n+k+40.

[0424] On the other hand, the contents of the present invention are not limited to uplink and / or downlink signal transmission and reception. For example, the present invention can be applied to direct communication between terminals. The base station in includes not only the base station but also the relay node. For example, the operation of the base station in the present invention is n) may be performed by the relay node.

[0425] The above-mentioned example of the proposed method is also included as one of the methods for implementing the present invention. The proposed method can be regarded as a separate system. However, it may be possible to realize the above in the form of a combination (or merging) of some of the proposed methods. The information on whether the proposed method is applied (or the information on the rules of the proposed method) is transmitted to the terminal by the base station. Or the transmitting terminal sends a predetermined signal (for example, a physical layer signal or a higher layer signal) to the receiving terminal. It may be provided that notice be given by

[0426] Example

[0427] FIG. 9 is a flowchart illustrating a signal transmission and reception method according to an embodiment of the present invention.

[0428] Referring to FIG. 9, an embodiment of the present invention is performed by a terminal to trigger a CSI report. receiving a PDCCH (S401); receiving a CSI-RS based on the PDCCH; and a step of receiving a CSI report based on the measurement result for the CSI-RS (S403). The method includes a step of transmitting a PUSCH including the PUSCH (S405).

[0429] In addition to the operations in Figure 9, you can also perform one or more of the operations described in 1 above. good.

[0430] For example, referring to 1.5 to 1.9, the CSI report is an aperiodic CSI report. . 1.8, μ PDCCH is the PDCCH containing DCI for triggering CSI This SCS setting is referred to as the first SCS setting. CSI-RS is triggered by the DCI The second SCS setting is the minimum of the SCS settings of the aperiodic CSI-RSs that have been It is expressed as μ UL is the SCS setting of the PUSCH on which the CSI report is transmitted, and the third S This is expressed as CS setting.

[0431] Referring to method (1.8-2a), the first SCS setting, the second SCS setting, and the third SCS setting If any one of the SCS settings is 5 or 6, HARQ-ACK or Even if TB is not included and there is no CPU dedicated to the terminal, the CSI calculation delay in Table 20 is In this case, delay requirement 2 is used and CSI calculation delay requirement 1 in Table 17 is not used.

[0432] Referring to Table 19, the conventional PUSCH does not include HARQ-ACK or TB, and If there is no CPU dedicated to the end, CSI computation delay requirement 1 in Table 17 is used. The present disclosure provides a first SCS setting, a second SCS setting, and a third SCS setting. The behavior when any one of the settings is 5 or 6 has been changed, so the CSI calculation delay request Item 1 is the first SCS setting, the second SCS setting, and the third SCS setting. 6, i.e., the first SCS setting, the second SCS setting, and the third SCS setting is used when the maximum value of is less than or equal to 3.

[0433] Referring to Table 17, CSI calculation delay requirement 1 is the lowest delay (Ultra-low latency). It is composed of a combination of Z and Z' for each SCS for low latency Referring to Table 20, CSI calculation delay requirement 2 is shorter than CSI calculation delay requirement 1. and consists of a combination of Z and Z' per SCS for higher delays.

[0434] Referring to Table 15, Z is the number of symbols from the last symbol of the PDCCH that triggers the CSI report. the interval from the next uplink symbol (start symbol of PUSCH) and the associated number of symbols Z' is the aperiodic CSI-RS resource and the aperiodic CSI-IM resource. NZP CSI-RS: The next uplink symbol from the last symbol of the last received signal The number of symbols associated with the interval to the symbol (start symbol of PUSCH). If there is no other signal received between CSI-RS and PUSCH, Z' is the CSI-RS is the number of symbols associated with the interval from the last symbol of the PUSCH to the start symbol of the PUSCH.

[0435] Referring to Method (1.9-2), the first SCS setting, the second SCS setting, and the third SCS setting If at least one of the SCS settings is 5 or 6, HARQ-ACK or Even if TB is not included and there is no CPU dedicated to the terminal, the CSI report is still All available CPUs (N CPu ) CSI-RS resource set for channel measurement The CPU is occupied by the number of CSI-RS resources in the CPU =K s ).

[0436] Referring to Table 21, the conventional PUSCH does not include HARQ-ACK or TB, and If there is no CPU dedicated to the terminal, the CSI report will be sent to all CPUs available to the terminal. Occupy U (O CPU =N CPU ) The present disclosure provides a first SCS configuration and a second SCS The behavior when at least one of the settings and the third SCS setting is 5 or 6 has been changed. Therefore, CSI reporting does not occupy all the CPU available to the terminal, which is the first SCS setting and If there is no 5 or 6 of the second and third SCS settings, i.e., the first Allowed when the maximum value of the SCS setting, the second SCS setting, and the third SCS setting is 3 or less. It is tolerated.

[0437] Also, referring to 1.1, the first PUCCH including the HARQ-ACK is transmitted. The interval between the slot and the second slot in which the HARQ-ACK and associated PDSCH are received. is determined based on the slot offset K1.
