Description

Method and device for transmitting and receiving signals in a wireless communication system

[0001] The present invention relates to a method and apparatus used in a wireless communication system.

[0002] Wireless communication systems are widely deployed to provide various types of communication services, such as voice and data. Typically, wireless communication systems are multiple access systems that support communication with multiple users by sharing available system resources (e.g., bandwidth, transmission power). Examples of multiple access systems include Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Orthogonal Frequency Division Multiple Access (OFDMA), and Single Carrier Frequency Division Multiple Access (SC-FDMA).

[0003] The technical problem to be achieved by the present invention is to provide a signal transmission and reception method and a device therefor for efficiently transmitting and receiving a reference signal and a measurement report in a wireless communication system.

[0004] The technical problems of the present invention are not limited to the technical problems described above, and other technical problems can be inferred from the embodiments of the present invention.

[0005] The present invention provides a method and device for transmitting and receiving signals in a wireless communication system.

[0006] As one aspect of the present invention, a method for transmitting and receiving a signal by a terminal in a wireless communication system is provided, the method comprising: receiving a first physical downlink control channel (PDCCH) including downlink control information (DCI) for scheduling a first physical uplink shared channel (PUSCH); receiving a CSI-RS on an aperiodic channel state information-reference signal (CSI-RS) resource; and transmitting a CSI report through the first PUSCH based on a measurement result for the CSI-RS.

[0007] In another aspect of the present invention, a method for transmitting and receiving a signal by a base station in a wireless communication system is provided, the method comprising: transmitting a first physical downlink control channel (PDCCH) including downlink control information (DCI) for scheduling a first physical uplink shared channel (PUSCH); transmitting a CSI-RS on an aperiodic CSI-reference signal (CSI-RS) resource; and receiving a CSI report triggered by the DCI through the first physical uplink shared channel (PUSCH) based on a measurement result for the CSI-RS.

[0008] As another aspect of the present invention, a device, a processor and a storage medium for performing one of the signal transmission and reception methods are provided.

[0009] In the above methods and devices, based on the first PUSCH overlapping with one or more second PUSCHs and one or more physical uplink control channels (PUCCHs), the PUSCH may be positioned after a first processing time from the last symbol in which the first signal is received. The first signal may be a signal including the symbol located at the very end of (i) the first PDCCH, (ii) all second PDCCHs including a DCI format for scheduling the second PUSCH, and (iii) all third PDCCHs scheduling a physical downlink shared channel (PDSCH) corresponding to hybrid automatic repeat and request acknowledgement (HARQ-ACK) information in the PUCCH or providing a DCI format.

[0010] In the above methods and devices, based on the smallest value among the SCS values ​​of the CSI-RSs associated with each of the first PDCCH, all the second PDCCHs, all the third PDCCHs, the first PUSCH, the second PUSCH, the CSI-RS, and all the second PDCCHs being 5 or 6, the first value added to the value of the CSI calculation delay requirement related to the first processing time may be set to be the same as when the smallest value is 3.

[0011] The above devices may include at least a terminal, a network, and an autonomous vehicle capable of communicating with other autonomous vehicles other than the above devices.

[0012] The above-described aspects of the present invention are only some of the preferred embodiments of the present invention, and various embodiments reflecting the technical features of the present invention can be derived and understood by a person having ordinary skill in the art based on the detailed description of the present invention described below.

[0013] According to one embodiment of the present invention, when a reference signal and a measurement report are transmitted and received between communication devices, there is an advantage in that more efficient signal transmission and reception can be performed through operations differentiated from the conventional invention.

[0014] The technical effects of the present invention are not limited to the technical effects described above, and other technical effects can be inferred from the embodiments of the present invention.

[0019] Figures 5 to 8 illustrate devices according to embodiments of the present invention.

[0020] The following technologies can be used in various wireless access systems, such as CDMA, FDMA, TDMA, OFDMA, and SC-FDMA. CDMA can be implemented using wireless technologies such as UTRA (Universal Terrestrial Radio Access) or CDMA2000. TDMA can be implemented using wireless technologies such as GSM (Global System for Mobile communications) / GPRS (General Packet Radio Service) / EDGE (Enhanced Data Rates for GSM Evolution). OFDMA can be implemented using wireless technologies such as IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802-20, and E-UTRA (Evolved UTRA). UTRA is a part of UMTS (Universal Mobile Telecommunications System). 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution) is a part of E-UMTS (Evolved UMTS) that uses E-UTRA, and LTE-A (Advanced) / LTE-A pro is an evolved version of 3GPP LTE. 3GPP NR (New Radio or New Radio Access Technology) is an evolved version of 3GPP LTE / LTE-A / LTE-A pro.

[0021] For clarity, the description is based on a 3GPP communication system (e.g., LTE, NR), but the technical idea of ​​the present invention is not limited thereto. LTE refers to technology after 3GPP TS 36.xxx Release 8. Specifically, LTE technology after 3GPP TS 36.xxx Release 10 is referred to as LTE-A, and LTE technology after 3GPP TS 36.xxx Release 13 is referred to as LTE-A pro. 3GPP NR refers to technology after TS 38.xxx Release 15. LTE / NR may be referred to as a 3GPP system. "xxx" refers to a standard document detail number. LTE / NR may be collectively referred to as a 3GPP system.

[0028] - 38.331: Radio Resource Control (RRC) protocol specification

[0029] Figure 1 illustrates the structure of a radio frame used in NR.

[0030] In NR, uplink (UL) and downlink (DL) transmissions are structured as frames. A radio frame is 10ms long and is defined as two 5ms half-frames (HF). Each half-frame is defined as five 1ms subframes (SF). A subframe is divided into one or more slots, and the number of slots in a subframe depends on the subcarrier spacing (SCS). Each slot contains 12 or 14 OFDM(A) symbols, depending on the cyclic prefix (CP). When normal CP is used, each slot contains 14 symbols. When extended CP is used, each slot contains 12 symbols. Here, the symbols can include OFDM symbols (or CP-OFDM symbols), SC-FDMA symbols (or DFT-s-OFDM symbols).

[0031] Table 1 illustrates that when CP is normally used, the number of symbols per slot, the number of slots per frame, and the number of slots per subframe vary depending on the SCS.

[0032] [Table 1]

[0033]

[0034] Table 2 illustrates that when extended CP is used, the number of symbols per slot, the number of slots per frame, and the number of slots per subframe vary depending on the SCS.

[0035] [Table 2]

[0036]

[0037] In an NR system, OFDM(A) numerology (e.g., SCS, CP length, etc.) may be set differently between multiple cells that are merged into a single user equipment (UE). Accordingly, the (absolute time) interval of a time resource (e.g., SF, slot, or TTI) (conveniently referred to as a TU (Time Unit)) consisting of the same number of symbols may be set differently between the merged cells.

[0038] NR supports multiple Orthogonal Frequency Division Multiplexing (OFDM) numerologies (e.g., subcarrier spacing, SCS) to support various 5G services. For example, a 15 kHz SCS supports wide areas in traditional cellular bands, while a 30 kHz / 60 kHz SCS can support dense urban areas, lower latency, and wider carrier bandwidth.

[0039] The NR frequency band is defined by two types of frequency ranges (FR) (FR1 / FR2). FR1 / FR2 can be configured as shown in Table 3 below. FR2 can also refer to millimeter wave (mmW).

[0040] [Table 3]

[0041]

[0042] Figure 2 illustrates the slot structure of an NR frame.

[0043] A slot contains multiple symbols in the time domain. For example, for a normal CP, one slot contains 14 symbols, and for an extended CP, one slot contains 12 symbols. A carrier contains multiple subcarriers in the frequency domain. An RB (Resource Block) is defined as multiple (e.g., 12) consecutive subcarriers in the frequency domain. Multiple RB interlaces (simply, interlaces) can be defined in the frequency domain. An interlace m ∈ {0, 1, ..., M-1} can be composed of (common) RBs {m, M+m, 2M+m, 3M+m, ...}. M represents the number of interlaces. A BWP (Bandwidth Part) is defined as multiple consecutive RBs (e.g., physical RBs, PRBs) in the frequency domain, and can correspond to one OFDM numerology (e.g., SCS(u), CP length, etc.). A carrier can contain up to N (e.g., 5) BWPs. Data communication is performed through activated BWPs, and only one BWP can be activated per terminal within a single cell / carrier. Each element in the resource grid is referred to as a Resource Element (RE), to which a single modulation symbol can be mapped.

[0044] In a wireless communication system, a terminal receives information from a base station via the downlink (DL), and the terminal transmits information to the base station via the uplink (UL). The information transmitted and received between the base station and the terminal includes data and various control information, and various physical channels / signals exist depending on the type / purpose of the information they transmit and receive. A physical channel corresponds to a set of resource elements (REs) that carry information derived from a higher layer. A physical signal corresponds to a set of resource elements (REs) used by the physical layer (PHY), but does not carry information derived from a higher layer. The higher layers include the Medium Access Control (MAC) layer, the Radio Link Control (RLC) layer, the Packet Data Convergence Protocol (PDCP) layer, and the Radio Resource Control (RRC) layer.

[0045] DL physical channels include Physical Broadcast Channel (PBCH), Physical Downlink Shared Channel (PDSCH), and Physical Downlink Control Channel (PDCCH). DL physical signals include DL Reference Signal (RS), Primary Synchronization Signal (PSS), and Secondary Synchronization Signal (SSS). DL RS includes Demodulation RS (DM-RS), Phase-tracking RS (PT-RS), and Channel-state information RS (CSI-RS). UL physical channels include Physical Random Access Channel (PRACH), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH). UL physical signals include UL RS. UL RS includes DM-RS, PT-RS, and Sounding RS (SRS).

[0046] Figure 3 shows an example of physical channels being mapped within a slot.

[0047] A DL control channel, DL or UL data, and UL control channel can all be included in a single slot. For example, the first N symbols in a slot can be used to transmit a DL control channel (hereinafter, DL control region), and the last M symbols in the slot can be used to transmit a UL control channel (hereinafter, UL control region). N and M are each integers greater than or equal to 0. A resource region (hereinafter, data region) between the DL control region and the UL control region can be used for DL ​​data transmission or UL data transmission. A time gap for DL-to-UL or UL-to-DL switching can exist between the control region and the data region. A PDCCH can be transmitted in the DL control region, and a PDSCH can be transmitted in the DL data region. Some symbols at the time of switching from DL to UL within a slot can be used as a time gap.

[0048] In the present invention, the base station may be, for example, a gNodeB.

[0049] Uplink (UL) physical channel / signal

[0050] (1) PUSCH

[0051] The PUSCH carries uplink data (e.g., UL-SCH TB) and / or uplink control information (UCI), and is transmitted based on a CP-OFDM (Cyclic Prefix-Orthogonal Frequency Division Multiplexing) waveform or a DFT-s-OFDM (Discrete Fourier Transform-spread-OFDM) waveform. When the PUSCH is transmitted based on a DFT-s-OFDM waveform, the UE transmits the PUSCH by applying transform precoding. For example, when transform precoding is disabled (e.g., transform precoding is disabled), the UE transmits the PUSCH based on the CP-OFDM waveform, and when transform precoding is enabled (e.g., transform precoding is enabled), the UE can transmit the PUSCH based on the CP-OFDM waveform or the DFT-s-OFDM waveform. PUSCH can be dynamically scheduled by PDCCH (dynamic scheduling) or semi-statically scheduled based on higher layer (e.g., RRC) signaling (and / or Layer 1 (L1) signaling (e.g., PDCCH)) (Configured Scheduling, CS). Therefore, in dynamic scheduling, PUSCH transmission is accompanied by PDCCH, but in CS, PUSCH transmission is not accompanied by PDCCH. CS includes Type-1 Configured Grant (CG) PUSCH transmission and Type-2 CG PUSCH transmission. In Type-1 CG, all parameters for PUSCH transmission are signaled by higher layers. In Type-2 CG, some of the parameters for PUSCH transmission are signaled by higher layers, and the rest are signaled by PDCCH. Basically, in CS, PUSCH transmission is not accompanied by PDCCH.

[0052] (2) PUCCH

[0053] PUCCH carries Uplink Control Information (UCI). UCI includes:

[0054] - SR (Scheduling Request): Information used to request UL-SCH resources.

[0055] - HARQ-ACK (Hybrid Automatic Repeat and reQuest Acknowledgement): This is a reception response signal for DL ​​signals (e.g., PDSCH, SPS release PDCCH). The HARQ-ACK response may include positive ACK (simply ACK), negative ACK (NACK), Discontinuous Transmission (DTX), or NACK / DTX. HARQ-ACK can be used interchangeably with A / N, ACK / NACK, HARQ-ACK / NACK, etc. HARQ-ACK can be generated on a TB basis / CBG basis.

[0056] - CSI (Channel Status Information): Feedback information for the DL channel. CSI includes the Channel Quality Indicator (CQI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), and Precoding Type Indicator (PTI).

[0057] Downlink (DL) physical channel / signal

[0058] (1) PDSCH

[0059] The PDSCH carries downlink data (e.g., DL-shared channel transport block, DL-SCH TB). The TB is encoded into a codeword (CW) and then transmitted after undergoing scrambling and modulation processes. A CW includes one or more code blocks (CBs). One or more CBs can be grouped into a single CB group (CBBG). Depending on the cell configuration, a PDSCH can carry up to two CWs. Scrambling and modulation are performed for each CW, and the modulation symbols generated from each CW are mapped to one or more layers. Each layer is precoded, mapped to resources along with the DMRS, and transmitted through the corresponding antenna port. PDSCH can be dynamically scheduled by PDCCH (dynamic scheduling) or semi-statically scheduled based on higher layer (e.g., RRC) signaling (and / or Layer 1 (L1) signaling (e.g., PDCCH)) (Configured Scheduling, CS). Therefore, in dynamic scheduling, PDSCH transmission is accompanied by PDCCH, whereas in CS, PDSCH transmission is not accompanied by PDCCH. CS includes semi-persistent scheduling (SPS).

[0060] (2) PDCCH

[0061] The PDCCH carries Downlink Control Information (DCI). For example, the PCCCH (i.e., DCI) carries the transmission format and resource allocation of the DL-SCH, frequency / time resource allocation information for the UL-SCH (shared channel), paging information for the PCH (paging channel), system information on the DL-SCH, frequency / time resource allocation information for upper-layer control messages such as the Random Access Response (RAR) transmitted on the PDSCH, transmission power control commands, and information regarding the activation / release of Configured Scheduling (SPS / CS). Various DCI formats are provided depending on the information contained within the DCI.

[0062] 1. Additional time for CSI delay

[0063] The above-mentioned contents can be applied in combination with the proposed methods described below, or can be supplemented to clarify the technical characteristics of the proposed methods.

[0064] In addition, the methods described below can be equally applied to the NR system (licensed band) or shared spectrum described above, and the technical ideas proposed in this specification can be modified or replaced to fit the terms, expressions, structures, etc. defined in each system so that they can be implemented in the corresponding systems.

[0065] For NR operation in bands above 52.6 GHz (e.g., FR2-2 band), SCS of 120 kHz, 480 kHz, and 960 kHz can be configured. In the case of 480 kHz and 960 kHz SCS introduced for FR2-2 band, the length of OFDM symbol is shortened compared to 120 kHz (e.g., 1 / 4 for 480 kHz, 1 / 8 for 960 kHz). Due to the change in symbol length and slot length, there may be changes in various timeline aspects such as PDCCH / PDSCH processing time and PDSCH / PUSCH preparation time.

[0066] A terminal can transmit (aperiodic) CSI reports on the PUSCH. In this case, the CSI report can be triggered by DCI. Existing 3GPP standards define a minimum time from the reception of a PDCCH containing DCI to the transmission of an uplink channel (e.g., PUSCH) containing CSI. A terminal must transmit a valid CSI report when this minimum time is met. This minimum time is defined as follows.

[0067] In the following two cases, when the CSI request field of a DCI triggers a CSI report(s) on PUSCH, the UE shall provide a valid CSI report for the n-th triggered report:

[0068] - The first uplink symbol carrying the corresponding CSI report, including the timing advance effect, is symbol Z. refIf the first uplink symbol to carry the corresponding CSI report(s) including the effect of the timing advance, starts no earlier than at symbol Z ref ), and

[0069] - The first uplink symbol carrying the nth CSI report, including timing advance effects, is symbol Z'. ref (if the first uplink symbol to carry the n-th CSI report including the effect of the timing advance, starts no earlier than at symbol Z' ref (n)).

[0070] If aperiodic CSI-RS is used for channel measurement for the nth triggered CSI report, Z ref T' from the end of the last symbol of the PDCCH that triggers the CSI report. proc,CSI =(Z)(2048+144)·κ2 -μ ·T c +T switch Later, CP is defined as an uplink symbol starting from Z' ref(n) is the end point of the last symbol among the following signals T' proc,CSI =(Z')(2048+144)·κ2 -μ ·T c It is defined as the uplink symbol at which CP starts later.

[0071] - Aperiodic CSI-RS resources for channel measurement

[0072] - Aperiodic CSI-IM (interference measurement) used for interference measurement

[0073] - Aperiodic NZP (non-zero power) CSI-RS for interference measurements

[0074] When an uplink switching gap is triggered, for UEs with the upper layer parameter uplinkTxSwitchingOption for uplink carrier aggregation set to 'dualUL', T switch is the same as the uplink switching section. In other cases, T switch =0. T switch Applies only when Z1 in Table 4 is used.

[0075] Z, Z' are CSI computation delay requirements, defined as Z=maxm=0,...,M-1(Z(m)), Z'=maxm=0,...,M-1(Z'(m)), where M is the number of CSI reports to be updated based on the CSI processing criteria and the UE's CPU usage as described in section 5.2.1.6 of 3GPP TS 38.214. (Z(m),Z'(m)) is selected from (Z1,Z'1) in Table 4 (CSI computation delay requirement 1) or (Z1,Z'1), (Z2,Z'2), (Z3,Z'3) in Table 5 (CSI computation delay requirement 2), depending on the condition satisfied by the m-th updated CSI report. The specific conditions for which Z, Z' values ​​are selected are given in section 5.4 of the 3GPP TS 38.214 document.

[0078] Tc=1 / (480000*4096) and κ=64.

[0079] μ is μ PDCCH , μ CSI-RS , μ UL As the minimum among them, μ PDCCH corresponds to the SCS (subcarrier spacing) of the PDCCH on which the DCI is transmitted, μ UL corresponds to the SCS of the PUSCH on which the CSI report will be transmitted, and μ CSI-RS corresponds to the SCS of aperiodic CSI-RS triggered by DCI.

[0080] When different types of UCIs are configured / instructed to be transmitted on multiple overlapping PUCCHs and / or PUSCHs, the conditions (in terms of timeline) for multiplexing all of the UCIs are specified as follows. In particular, with respect to CSI reporting, the conditions for the minimum time required between a PDCCH (e.g., triggering the CSI report) and an UL channel / signal (e.g., PUSCH) are specified as follows.

[0081] If a terminal transmits multiple overlapping PUCCHs in a slot or multiple overlapping PUCCH(s) and PUSCH(s) in a slot, and the terminal is configured to multiplex UCIs of different UCI types or different priority indices within a PUCCH, and at least one of the multiple overlapping PUCCHs or PUSCHs is a response to a DCI format detection by the terminal, the terminal multiplexes all UCIs of different UCI types or different priority indices if the following conditions are satisfied: If one of the PUCCH transmissions or PUSCH transmissions is a response to a DCI format detection by the terminal, the terminal expects the first symbol S0 of the earliest PUCCH or PUSCH in the group of overlapping PUCCHs and PUSCHs within the slot to satisfy the following timeline conditions:

[0082] Timeline Conditions:

[0083] If there is an aperiodic CSI multiplexed on a PUSCH within a group of overlapping PUCCHs and PUSCHs, S0 is the CP after the end of the last symbol of the following first signals T_(proc,CSI)^mux=max((Z+d)·(2048+144)·κ2 -μ ·T c +T switch ,d 2,2 ) is not in front of a symbol starting with .

[0084] Signal 1:

[0085] - Any PDCCH with the DCI format scheduling an overlapping PUSCH.

[0086] - Any PDCCH scheduling a PDSCH, or providing a DCI format, with corresponding HARQ-ACK information in an overlapping PUCCH in the slot.

[0087] μ corresponds to the smallest SCS setting among the SCS settings of PDCCHs, the smallest SCS setting for a group of overlapping PUSCHs, and the smallest SCS setting of a CSI-RS associated with a DCI format that schedules a PUSCH including aperiodic CSI reporting.

[0088] For μ=0,1, d=2, for μ=2, d=3, for μ=3, d=4.

[0089] Z, κ, T c , T switch is as previously defined.

[0090] If the scheduling DCI triggers the switching of the BWP, d 2,2 is equal to the switching time. Otherwise, d 2,2 =0.

[0091] T_(proc,CSI)^mux can be understood as the minimum interval from the last symbol of the PDCCH to the first symbol of the UL signal (e.g., PUSCH) (where the corresponding CSI report is transmitted).

[0092] Meanwhile, this operation can also be supported for μ=5 and / or μ=6 in the FR2-2 band, for which the T_(proc,CSI)^mux formula needs to be defined for μ=5,6 as well. In this specification, the d value for μ=5,6 is proposed through one (or a combination of two or more) of the following methods.

[0093] Method 1-1: The d value for μ=5 is defined as 4 times the d value for μ=3, and the d value for μ=6 is defined as 8 times the d value for μ=3. That is, d=16 for μ=5, and d=32 for μ=6. This method can maintain the complexity of the terminal because the terminal can process a signal set to 480 / 960kHz SCS or have a processing / preparation timeline similar to that of a 120kHz signal when the signal is transmitted.

[0094] Method 1-2: The d value for μ=5 and / or μ=6 can be defined (identically) as the d value for μ=3 scaled by a factor of 4 or 8. That is, d=16 for μ=5,6 or d=32 for μ=5,6. This method can have the advantage of timeline-wise similar to Method 1-1, and also, since the d value for μ=5,6 is fixed to one, the additional time caused by the actual "d" can be different for μ=5,6 respectively.

[0095] Method 1-3: The d value for μ=5 and / or μ=6 can be defined as the same value as the d value for μ=3 (i.e., d=4). That is, d=4 for μ=5,6. This method can be useful when Z for μ=5,6 is defined / set to be sufficiently large. That is, since no separate d value is defined, and the d values ​​for μ=3,5,6 are defined identically, the impact of the specification is minimized, and the additional time caused by the actual "d" can be applied differently for each μ.

[0096] Method 1-4: The d value for μ=5 and / or μ=6 can be defined as 0. That is, d=0 for μ=5,6. This method can be useful when Z for μ=5,6 is defined / set to be sufficiently large. That is, since the Z value for μ=5,6 is defined / set to be sufficiently large, it can have advantages in terms of resource efficiency and latency by minimizing the additional time incurred due to the actual "d".

[0097] Method 1-5: The d value for μ=5 can be defined as the d value when μ=3 plus 2 (i.e., d=6), and the d value for μ=6 can be defined as the d value when μ=3 plus 3 (or 4) (i.e., d=7 or d=8). That is, d=6 for μ=5, and d=7 for μ=6 (or d=8 for μ=6). This method is based on the fact that the increase in the d value for μ=2 compared to the conventional μ=0,1, or the increase in the d value for μ=3 compared to μ=2 is 1 symbol. This method can also be useful when Z for μ=5,6 is defined / set sufficiently large. That is, since the Z value for μ=5,6 is defined / set sufficiently large, it can have advantages in terms of resource efficiency and delay by minimizing the additional time caused by the actual "d".

[0098] Additionally, with respect to CSI reporting, the conditions for the minimum time required between the reception time of the signal / channel (e.g., CSI-RS) used for measurement for the CSI report and the UL channel / signal (e.g., PUSCH) transmitting the CSI report (calculated therefrom) are as follows.

[0099] If there is one or more aperiodic CSI reports multiplexed on a PUSCH within a group of overlapping PUCCHs and PUSCHs, and S0 is the CP after the end of the last symbol of the next second signals, Z'_(proc,CSI)^mux= (Z'+d)(2048+144)·κ2 -μ ·T c If the next uplink symbol starting from Z'_ref^mux is present, the terminal is not requested to update the CSI report for the triggered CSI report n.

[0100] Symbols of the second signals:

[0101] - The last symbol of the aperiodic CSI-RS resource for channel measurement, and

[0102] - The last symbol of the aperiodic CSI-IM used for interference measurement, and

[0103] - When aperiodic CSI-RS is used for channel measurement for triggered CSI report n, the last symbol of the aperiodic NZP CSI-RS for interference measurement

[0104] μ corresponds to the smallest SCS configuration among the SCS configurations of PDCCHs scheduling PUSCHs, the smallest SCS configuration of aperiodic CSI-RSs associated with the DCI format provided by PDCCHs triggering aperiodic CSI reporting, and the smallest SCS configurations of overlapped PUCCHs and PUSCHs.

[0105] For μ=0,1, d=2, for μ=2, d=3, for μ=3, d=4.

[0106] Z', κ, T c is as previously defined.

[0107] Z'_(proc,CSI)^mux can be understood as the minimum interval from the last symbol of the signal / channel for measurement (e.g., CSI-RS) to the first symbol of the UL signal (e.g., PUSCH) on which the corresponding CSI report is transmitted.

[0108] Meanwhile, this operation can also be supported for μ=5 and / or μ=6 in the FR2-2 band, for which the Z'_(proc,CSI)^mux formula needs to be defined for μ=5,6 as well. In this specification, the d value for μ=5,6 is proposed through one (or a combination of two or more) of the following methods.

[0109] Method 2-1: The d value for μ=5 is defined as 4 times the d value for μ=3, and the d value for μ=6 is defined as 8 times the d value for μ=3. That is, d=16 for μ=5, and d=32 for μ=6. This method can maintain the complexity of the terminal because the terminal can process a signal set to 480 / 960kHz SCS or have a processing / preparation timeline similar to that of a 120kHz signal when the signal is transmitted.

[0110] Method 2-2: The d value for μ=5 and / or μ=6 can be defined (identically) as the d value when μ=3 scaled by a factor of 4 or 8. That is, d=16 for μ=5,6 or d=32 for μ=5,6. This method can have the advantage of timeline-wise similar to Method 2-1, and also, since the d value for μ=5,6 is fixed to one, the additional time caused by the actual "d" can be different for μ=5,6 respectively.

[0111] Method 2-3: The d value for μ=5 and / or μ=6 can be defined as the same value as the d value for μ=3 (i.e., d=4). That is, d=4 for μ=5,6. This method can be useful when Z for μ=5,6 is defined / set to be sufficiently large. That is, since no separate d value is defined, and the d values ​​for μ=3,5,6 are defined identically, the impact of the specification is minimized, and the additional time caused by the actual "d" can be applied differently for each μ.

[0112] Method 2-4: The d value for μ=5 and / or μ=6 can be defined as 0. That is, d=0 for μ=5,6. This method can be useful when Z for μ=5,6 is defined / set to be sufficiently large. That is, since the Z value for μ=5,6 is defined / set to be sufficiently large, it can have advantages in terms of resource efficiency and latency by minimizing the additional time caused by the actual "d".

[0113] Method 2-5: The d value for μ=5 can be defined as the d value when μ=3 plus 2 (i.e., d=6), and the d value for μ=6 can be defined as the d value when μ=3 plus 3 (or 4) (i.e., d=7 or d=8). That is, d=6 for μ=5, and d=7 for μ=6 (or d=8 for μ=6). This method is based on the fact that the increase in the d value for μ=2 compared to the conventional μ=0,1, or the increase in the d value for μ=3 compared to μ=2 is 1 symbol. This method can also be useful when Z for μ=5,6 is defined / set sufficiently large. That is, since the Z value for μ=5,6 is defined / set sufficiently large, it can have advantages in terms of resource efficiency and delay by minimizing the additional time caused by the actual "d".

[0114] The methods proposed in this specification are described for μ=5 and / or μ=6, but are not limited thereto. The proposed methods can be equally applied to numerologies or SCSs greater than μ=6 (i.e., 960 kHz). For example, for x>6, the proposed methods can be extended in the following manner.

[0115] - The d value for μ=x is defined as 0

[0116] - The d value for μ=x is defined as 4

[0117] - The d value for μ=x is defined as y times the d value for μ=3. In this case, y is defined as 2^(x-3).

[0118] Meanwhile, the present invention is not limited to the transmission and reception of uplink and / or downlink signals. For example, the present invention can also be used in direct communication between terminals. Furthermore, the base station in the present invention may include not only a base station but also a relay node. For example, the base station operations in the present invention may be performed by the base station, but may also be performed by a relay node.

[0119] It is clear that the examples of the proposed methods described above can also be considered as a type of proposed methods, as they can be included as one of the implementation methods of the present invention. In addition, the proposed methods described above can be implemented independently, but can also be implemented in the form of a combination (or merge) of some of the proposed methods. Information on whether the proposed methods are applicable (or information on the rules of the proposed methods) can be defined as a rule so that the base station notifies the terminal or the transmitting terminal notifies the receiving terminal through a predefined signal (e.g., a physical layer signal or a higher layer signal).

[0120] Implementation example

[0121] Figure 4 is a flowchart for a signal transmission and reception method.

[0122] Referring to FIG. 4, an embodiment performed by a terminal may be configured to include a step of receiving DCI for scheduling a PUSCH (S501), a step of receiving a CSI-RS on an aperiodic CSI-RS resource (S503), and a step of transmitting a CSI report through the PUSCH based on a measurement result for the CSI-RS (S505).

[0123] Referring to FIG. 4, an embodiment performed by a base station may be configured to include a step of transmitting DCI for scheduling a PUSCH (S501), a step of transmitting a CSI-RS on an aperiodic CSI-RS resource (S503), and a step of receiving a CSI report through a PUSCH based on a measurement result for the CSI-RS (S505).

[0124] In addition to the operations of FIG. 4, one or more of the operations described in Section 1 may be additionally performed.

[0125] Referring to Section 1, the first symbol S0 of the most advanced PUCCH or PUSCH in a group of overlapping PUCCHs and PUSCHs within a slot is from the last symbol in which the PDCCH was received. It is not transmitted earlier than the first symbol after T_(proc,CSI)^mux (the first processing time), and it is not transmitted earlier than Z'_ref^mux, which is the first symbol after Z'_(proc,CSI)^mux (the second processing time), from the last of the three symbols.

[0126] - The last symbol of the aperiodic CSI-RS resource for channel measurement

[0127] - The last symbol of the aperiodic CSI-IM used for interference measurement.

[0128] - When aperiodic CSI-RS is used for channel measurements for triggered CSI report n, the last symbol of the aperiodic NZP CSI-RS for interference measurements or all triggered sub-sets.

[0129] Referring to the formulas related to the first processing time and the second processing time, Z+d is used to determine the first processing time, and Z'+d is used to determine the second processing time. Z and Z' are the CSI calculation delay requirements described above, and Z and Z' are selected as a pair of values ​​from Tables 4 and 5 depending on specific conditions.

[0130] The d value added to Z is determined based on the smallest value among the SCS settings of PDCCHs, the smallest SCS setting for a group of overlapping PUSCHs, and the smallest SCS setting of a CSI-RS associated with a DCI format that schedules a PUSCH including aperiodic CSI reporting.

[0131] The d value added to Z' is determined based on the smallest value among the SCS settings of the PDCCHs scheduling the PUSCHs, the smallest SCS settings of the aperiodic CSI-RSs associated with the DCI format provided by the PDCCHs triggering the aperiodic CSI report, and the smallest SCS settings of the overlapped PUCCHs and PUSCHs.

[0132] Conventionally, each d value is defined only up to the case where the smallest SCS value is 3, and in the present embodiment, for example, referring to methods 1-3 and 2-3, for the case where the smallest SCS value is 5 or 6, the d value for the first processing time (first value) and the d value for the second processing time (second value) can both be set to be the same (4) as when the smallest SCS value is 3.

[0133] Only the first and second values ​​based on methods 1-3 and 2-3 are exemplified, but one of methods 1-1 to 1-5 and one of methods 2-1 to 2-5 can be arbitrarily combined.

[0134] Additionally, based on the smallest SCS value exceeding 6, each d value associated with the first processing time and / or the second processing time can be (independently) determined by one of the methods for when μ=x.

[0135] In addition to the operations described with respect to FIG. 4, one or more of the operations described with respect to FIGS. 1 to 3 and / or the operations described in Section 1 may be additionally performed in combination.
