[0006] Technical solution

[0007] This disclosure provides a method and apparatus for transmitting and receiving signals in a wireless communication system.

[0008] In one aspect of this disclosure, a method for transmitting and receiving signals by a user equipment (UE) in a wireless communication system is provided, the method comprising the steps of: receiving a first physical downlink control channel (PDCCH) including downlink control information (DCI) for scheduling a first physical uplink shared channel (PUSCH); receiving CSI-RS in an aperiodic channel state information-reference signal (CSI-RS) resource; and transmitting a CSI report via the first PUSCH based on measurement results from the CSI-RS.

[0021] Figure 4 This is a diagram illustrating a method for transmitting and receiving signals according to an embodiment of the present disclosure.

[0022] Figures 5 to 8 An apparatus according to an embodiment of the present disclosure is illustrated. Detailed Implementation

[0023] The following technologies can be used in various wireless access systems such as 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). CDMA can be implemented as radio technologies such as Universal Terrestrial Radio Access (UTRA) or CDMA2000. TDMA can be implemented as radio technologies such as Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS), and Enhanced Data Rate GSM Evolution (EDGE). OFDMA can be implemented as radio technologies such as IEEE 802.11 (Wireless Fidelity (WiFi)), IEEE 802.16 (Global Microwave Access Interoperability (WiMAX)), IEEE 802.20, and Evolved UTRA (E-UTRA). UTRA is part of the Universal Mobile Telecommunications System (UMTS). The 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) is part of Evolved UMTS using E-UTRA (E-UMTS), and LTE-Advanced (LTE-A) is an evolution of 3GPP LTE. 3GPP New Radio or New Radio Access Technology (NR) is an evolution of 3GPP LTE / LTE-A.

[0024] For clarity, this disclosure will be described in the context of 3GPP communication systems (e.g., LTE and NR), which should not be construed as limiting the spirit of this disclosure. LTE refers to technologies beyond 3GPP TS 36.xxx version 8. Specifically, LTE technologies beyond 3GPP TS 36.xxx version 10 are referred to as LTE-A, and LTE technologies beyond 3GPP TS 36.xxx version 13 are referred to as LTE-A pro. 3GPP NR is a technology beyond 3GPP TS 38.xxx version 15. LTE / NR may be referred to as a 3GPP system. “xxx” specifies the technical specification number. LTE / NR may be collectively referred to as a 3GPP system. Background techniques, terms, abbreviations, etc., as used herein refer to technical specifications published prior to this disclosure. For example, the following documents may be referenced.

[0026] -38.211: Physical Channel and Modulation

[0027] -38.212: Multiplexing and Channel Coding

[0028] -38.213: Physical layer process used for control

[0029] -38.214: Physical layer procedures for data

[0030] -38.300: General Description of NR and NG-RAN

[0031] -38.331: Radio Resource Control (RRC) Protocol Specification

[0032] Figure 1 The radio frame structure used for NR is shown.

[0033] In NR, UL and DL transmissions are configured on a frame-by-frame basis. Each radio frame is 10ms long and is divided into two 5ms half-frames. Each half-frame is further divided into five 1ms subframes. Subframes are divided into one or more time slots, and the number of time slots in a subframe depends on the subcarrier spacing (SCS). Depending on the cyclic prefix (CP), each time slot includes 12 or 14 OFDM(A) symbols. When using normal CP, each time slot includes 14 OFDM symbols. When using extended CP, each time slot includes 12 OFDM symbols. Symbols can include OFDM symbols (or CP-OFDM symbols) and SC-FDMA symbols (or Discrete Fourier Transform-Extended-OFDM (DFT-s-OFDM) symbols).

[0034] Table 1 exemplarily shows how the number of symbols per slot, the number of slots per frame, and the number of slots per subframe vary according to SCS under normal CP conditions.

[0035] [Table 1]

[0036] Table 2 shows the number of symbols per slot, the number of slots per frame, and the number of slots per subframe in the case of extended CP, depending on the SCS.

[0037] [Table 2]

[0038] In NR systems, different OFDM(A) parameter sets (e.g., SCS, CP length, etc.) can be configured for multiple cells aggregated for a UE. Therefore, the (absolute time) duration of time resources (e.g., subframes, slots, or transmission time intervals (TTI)) consisting of the same number of symbols (for convenience, referred to as time units (TU)) can be configured differently among the aggregated cells.

[0039] In NR, various parameter sets (or SCSs) can be supported to support a wide range of 5G services. For example, a 15kHz SCS can support wide areas in traditional cellular bands, while a 30kHz or 60kHz SCS can support dense urban areas, lower latency, and wide carrier bandwidth. For an SCS of 60kHz or higher, bandwidths greater than 24.25kHz can be supported to overcome phase noise.

[0040] The NR band can be defined by two types of frequency ranges, FR1 and FR2. FR1 and FR2 can be configured as shown in Table 3 below. FR2 can be millimeter wave (mmW).

[0041] [Table 3]

[0042] Figure 2 This shows the resource grid during the duration of a time slot.

[0043] A time slot comprises multiple symbols in the time domain. For example, a time slot may contain 14 symbols in normal CP and 12 symbols in extended CP. A carrier comprises multiple subcarriers in the frequency domain. A resource block (RB) can be defined by multiple (e.g., 12) consecutive subcarriers in the frequency domain. Multiple RB interleavings (simply called interleavings) can be defined in the frequency domain. An interleaving m∈{0, 1, ..., M-1} can consist of (common) RBs {m, M+m, 2M+m, 3M+m, ...}. M represents the number of interleavings. A bandwidth portion (BWP) can be defined by multiple consecutive (physical) RBs ((P)RBs) in the frequency domain and corresponds to a set of parameters (e.g., SCS, CP length, etc.). A carrier may include up to N (e.g., five) BWPs. Data communication can be performed in active BWPs, and only one BWP can be enabled for a UE. Individual elements in a resource grid can be called resource elements (REs) and can be mapped to a complex symbol.

[0044] In a wireless communication system, the UE receives information from the BS in the downlink (DL) and transmits information to the BS in the uplink (UL). The information exchanged between the BS and the UE includes data and various control information, and various physical channels / signals exist depending on the type / purpose of the information exchanged. Physical channels correspond to a set of resource elements (REs) carrying information originating from higher layers. Physical signals correspond to a set of REs used by the physical layer but not carrying information originating from higher layers. Higher layers include the Media Access Control (MAC) layer, Radio Link Control (RLC) layer, Packet Data Convergence Protocol (PDCP) layer, Radio Resource Control (RRC) layer, etc.

[0045] DL physical channels include the Physical Broadcast Channel (PBCH), Physical Downlink Shared Channel (PDSCH), and Physical Downlink Control Channel (PDCCH). DL physical signals include the DL Reference Signal (RS), Primary Synchronization Signal (PSS), and Secondary Synchronization Signal (SSS). DL RS includes the Demodulation Reference Signal (DM-RS), Phase Tracking Reference Signal (PT-RS), and Channel State Information Reference Signal (CSI-RS). UL physical channels include the 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 Reference Signal (SRS).

[0046] Figure 3 An example of a self-contained time slot structure is shown.

[0047] In NR systems, frames have a self-contained structure where the DL control channel, DL or UL data, and UL control channel can all be contained within a single time slot. For example, the first N symbols in a time slot (hereinafter, the DL control region) can be used to transmit the DL control channel, and the last M symbols in the time slot (hereinafter, the UL control region) can be used to transmit the UL control channel. N and M are integers greater than or equal to 0. The resource region between the DL control region and the UL control region (hereinafter, the data region) can be used for either DL data transmission or UL data transmission. For example, consider the following configuration. The parts are listed in chronological order.

[0048] In this disclosure, the base station (BS) may be, for example, a gNode B (gNB).

[0049] UL physical channel / signal

[0050] (1) PUSCH

[0051] The PUSCH can carry UL data (e.g., Uplink Shared Channel (UL-SCH) transport block (TB)) and / or Uplink Control Information (UCI). The PUSCH can be transmitted based on a Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) waveform or a Discrete Fourier Transform Extended OFDM (DFT-s-OFDM) waveform. When the PUSCH is transmitted based on a DFT-s-OFDM waveform, the UE can transmit the PUSCH by applying transform precoding. For example, when transform precoding is not allowed (e.g., when transform precoding is disabled), the UE can transmit the PUSCH based on a CP-OFDM waveform. When transform precoding is allowed (e.g., when transform precoding is enabled), the UE can transmit the PUSCH based on either a CP-OFDM waveform or a DFT-s-OFDM waveform. PUSCH transmissions can be dynamically scheduled by PDCCH (dynamic scheduling) or semi-statically scheduled by higher-layer signaling (e.g., RRC signaling) (and / or Layer 1 (L1) signaling (e.g., PDCCH)) (Configured Scheduling (CS)). Therefore, in dynamic scheduling, PUSCH transmissions can be associated with PDCCH, while in CS, PUSCH transmissions may not be associated with PDCCH. CS can include PUSCH transmissions based on Type 1 Configuration Certification (CG) and PUSCH transmissions based on Type 2 CG. For Type 1 CG, all parameters for PUSCH transmissions can be signaled by higher layers. For Type 2 CG, some parameters for PUSCH transmissions can be signaled by higher layers, while the rest can be signaled via PDCCH. Essentially, in CS, PUSCH transmissions may not be associated with PDCCH.

[0052] (2) PUCCH

[0053] PUCCH can transmit UCI. UCI includes the following information.

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

[0055] - Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK): HARQ-ACK is a received signal in response to DL signals (e.g., PDSCH, SPS release PDCCH, etc.). HARQ-ACK responses can include affirmative ACK (ACK), negative ACK (NACK), DTX (discontinuous transmission), or NACK / DTX. HARQ-ACK can be used interchangeably with A / N, ACK / NACK, and HARQ-ACK / NACK. HARQ-ACK can be generated based on TB / CBG.

[0056] - Channel State Information (CSI): CSI is feedback information about the DL channel. CSI includes Channel Quality Indicator (CQI), Rank Indicator (RI), Precoding Matrix Indicator (PMI), Precoding Type Indicator (PTI), etc.

[0057] DL physical channel / signal

[0058] (1) PDSCH

[0059] PDSCH carries DL data (e.g., DL Shared Channel Transport Block (DL-SCH TB)). TBs are encoded into codewords (CWs) and then transmitted after scrambling and modulation. Each CW comprises one or more code blocks (CBs). One or more CBs can be grouped into a code block group (CBG). Depending on the cell configuration, PDSCH can carry up to two CWs. Scrambling and modulation can be performed on each CW, and the modulation symbols generated from each CW can be mapped to one or more layers. Each layer can be pre-coded and mapped to resources along with DMRS and transmitted on the corresponding antenna port. PDSCH can be dynamically scheduled by PDCCH (dynamic scheduling). Alternatively, PDSCH can be 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, while in CS, PDSCH transmission may not be accompanied by PDCCH. CS may include semi-persistent scheduling (SPS).

[0060] (2) PDCCH

[0061] The PDCCH carries downlink control information (DCI). For example, the PDCCH (i.e., DCI) can carry: the transmission format and resource allocation of the DL-SCH; frequency / time resource allocation information for the uplink shared channel (UL-SCH); paging information for the paging channel (PCH); system information for the DL-SCH; time / frequency resource allocation information for higher-layer control messages such as random access responses (RARs) transmitted on the PDSCH; power control commands; and information about SPS / CS activation / deactivation. Various DCI formats can be provided based on the information in the DCI.

[0062] 1. Additional time for CSI delay

[0063] The above content can be applied in conjunction with the methods proposed in this disclosure (described later). Alternatively, the content can illustrate the technical features of the methods proposed in this disclosure.

[0064] Furthermore, the following methods can be equally applied to the aforementioned NR systems (licensed bands) or shared spectrum. Therefore, it is evident that the terminology, expressions, and structure in this document can be modified to suit the system in order to implement the technical concepts of this disclosure in the corresponding system.

[0065] SCSs of 120 kHz, 480 kHz, or 960 kHz can be used for NR operation in bands above 52.6 GHz. For the newly introduced 480 kHz and 960 kHz SCSs, the length of OFDM symbols becomes shorter than that of OFDM symbols with the 120 kHz SCS (e.g., 1 / 4 for 480 kHz and 1 / 8 for 960 kHz). Due to the shortened symbol and slot lengths, various changes may occur in the timeline, such as PDCCH / PDSCH processing time and PDSCH / PUSCH preparation time.

[0066] The UE can send (non-periodic) CSI reports on the PUSCH. In this case, the CSI report can be triggered by the DCI. Traditional 3GPP standard documents define the minimum time required from receiving the PDCCH carrying the DCI to sending the UL channel carrying the CSI (e.g., the PUSCH). When this minimum time is met, the UE should send a valid CSI report. The minimum time is defined as follows.

[0067] In the following two cases, when the CSI request field in the DCI triggers a CSI report on the PUSCH, the UE should provide a valid CSI report for the nth triggered report.

[0068] - If the first UL symbol used to carry the CSI report (including the effects of timing advance) is not earlier than symbol Z ref The beginning, and

[0069] - If the first UL symbol used to carry the nth CSI report (including the effects of timing advance) is not earlier than symbol Z' ref (n) Begins.

[0070] When aperiodic CSI-RS is used for channel measurements to trigger the nth CSI report, Z ref The CP is defined as the T' starting from the end of the last symbol of the PDCCH that triggered the CSI report. proc,CSI =(Z)(2048+144)·κ2 -μ ·T c +T switch The UL symbol that begins after that, and Z' ref (n) is defined as CP starting from the end of T' of the last symbol in the following signals. proc,CSI=(Z')(2048+144)·κ2 -μ ·T c The UL symbol that follows.

[0071] - Aperiodic CSI-RS resources for channel measurements.

[0072] - Non-periodic CSI-Interference Measurement (IM) for interference measurement.

[0073] - Non-periodic non-zero power (NZP) CSI-RS for interference measurements.

[0074] When a UL handover gap is triggered, for a UE configured with the higher-layer parameter uplinkTxSwitchingOption set to "dualUL" for UL carrier aggregation (CA), T switch Equal to the UL switching cycle. In other cases, T switch =0. T is applied only when Z1 in Table 4 is used. switch .

[0075] Z and Z' are the CSI calculation delay requirements, defined as Z = max m=0,...,M-1 (Z(m)) and Z'=max m=0,...,M-1 (Z'(m)), where M is the number of CSI reports updated based on the CSI processing criteria and UE CPU usage 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 calculation delay requirement 1) or (Z1, Z'1), (Z2, Z'2), and (Z3, Z'3) in Table 5 (CSI calculation delay requirement 2) according to the conditions satisfied by the m-th updated CSI report. The specific conditions used to select a particular Z and Z' value are based on Section 5.4 of 3GPP TS 38.214.

[0076] [Table 4]

[0077] [Table 5]

[0078] Tc=1 / (480000) 4096) and κ=64.

[0079] μ is μ PDCCH μ CSI-RS and μ UL The minimum value among them, where μ PDCCH Corresponding to the subcarrier spacing (SCS) of the PDCCH carrying DCI, μ CSI-RSThe SCS corresponding to the PUSCH carrying the CSI report, and μ UL SCS corresponds to the non-periodic CSI-RS triggered by DCI.

[0080] When different types of UCIs are configured / indicated to be transmitted on multiple overlapping PUCCHs and / or PUSCHs, the conditions for multiplexing UCIs (in terms of timeline) are specified as follows. Specifically, regarding CSI reporting, the minimum time required between the PDCCH (e.g., triggering CSI reporting) and the UL channel / signal (e.g., PUSCH) is specified as follows.

[0081] When a UE transmits multiple overlapping PUCCHs or multiple overlapping PUCCHs and PUSCHs in a time slot, the UE is configured to multiplex UCIs of different UCI types or different priority indices within a single PUCCH, and at least one of the multiple overlapping PUCCHs or PUSCHs is a response to a DCI format detected by the UE. The UE multiplexes all UCIs of different UCI types or different priority indices if the following condition is met: When one of the PUCCH or PUSCH transmissions is a response to a DCI format detected by the UE, the UE expects the first symbol S0 of the earliest PUCCH or PUSCH in the group of overlapping PUCCHs and PUSCHs within the time slot to satisfy the following timeline condition.

[0082] Timeline conditions: When there is an aperiodic CSI multiplexed in the PUSCH within a group of overlapping PUCCH and PUSCH, S0 is not located at T_(proc,CSI)^mux=max((Z+d)·(2048+144)·κ2 from the end of the last symbol in the first signal below. -μ ·T c +T switch ,d 2,2 The symbol that begins after ) and before .

[0083] First signal: - Any PDCCH with DCI format that has scheduling overlapping PUSCH.

[0084] - Schedule PDSCH or any PDCCH in DCI format, with corresponding HARQ-ACK information in the overlapping PUCCH in the time slot.

[0085] μ corresponds to the minimum SCS configuration in the PDCCH SCS configuration, the minimum SCS configuration for the group of overlapping PUSCHs, and the minimum SCS configuration of CSI-RS associated with the DCI format of PUSCHs that carry aperiodic CSI reports for scheduling.

[0086] For μ=0 and 1, d=2; for μ=2, d=3; for μ=3, d=4.

[0087] Z, κ, T c and T switch As defined above.

[0088] When the scheduling DCI triggers a BWP handover, d 2,2 It equals the switching time. Otherwise, d 2,2 =0.

[0089] 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) (carrying the corresponding CSI report).

[0090] This operation can also be supported for μ=5 and / or μ=6 in the FR2-2 band, and for this purpose, the T_(proc,CSI)^mux formula needs to be defined for μ=5 and 6. In this disclosure, the d values ​​for μ=5 and 6 are proposed by one (or a combination of two or more) of the following methods.

[0091] 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, for μ=5, d=16, and for μ=6, d=32. This method can maintain the complexity of the UE because when the UE processes a signal configured with a 480 / 960-kHz SCS, or when transmitting such a signal, it can have a processing / preparation timeline similar to that of a 120-kHz signal.

[0092] Method 1-2: The d value for μ=5 and / or μ=6 can be (equally) defined as the value obtained by scaling the d value for μ=3 by a factor of 4 or 8. That is, d=16 for μ=5 and 6, or d=32 for μ=5 and 6. This method can have the advantages of Method 1-1 in terms of timeline, and by fixing the d value for μ=5 and 6 to a single value, the additional time actually occurring due to "d" can also vary for each of μ=5 and μ=6.

[0093] Methods 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 and 6. This method can be useful when Z for μ=5 and 6 is defined / configured to be sufficiently large. That is, since no separate d value is defined and the d values ​​for μ=3, 5 and 6 are defined the same, the impact on the specification is minimized, and the additional time actually occurring due to "d" can be applied differently for each μ.

[0094] Methods 1-4: The value of d for μ=5 and / or μ=6 can be defined as 0. That is, d=0 for μ=5 and 6. This method can be useful when Z for μ=5 and 6 is defined / configured to be sufficiently large. In other words, since the value of Z for μ=5 and 6 is defined / configured to be sufficiently large, the advantages in terms of resource efficiency and latency can be obtained by minimizing the additional time actually incurred due to "d".

[0095] Methods 1-5: The d value for μ=5 can be defined as the value obtained by adding 2 to the d value for μ=3 (i.e., d=6), and the d value for μ=6 can be defined as the value obtained by adding 3 (or 4) to the d value for μ=3 (i.e., d=7 or d=8). That is, for μ=5, d=6, and for μ=6, d=7 (or for μ=6, d=8). This method is based on the fact that the d value for μ=2 is a sign relative to the increments of μ=0 and 1, or the d value for μ=3 is a sign relative to the increments of μ=2. This method can also be useful when Z for μ=5 and 6 is defined / configured to be sufficiently large. That is, since the Z values ​​for μ=5 and 6 are defined / configured to be sufficiently large, advantages in resource efficiency and latency can be obtained by minimizing the additional time actually incurred due to "d".

[0096] Furthermore, regarding CSI reports, the minimum time required between the reception time of the signal / channel (e.g., CSI-RS) used for measurements for CSI reports and the UL channel / signal (e.g., PUSCH) carrying the CSI report (calculated based on the reception time) is as follows.

[0097] When there are one or more non-periodic CSI reports multiplexed in the PUSCH within a group of overlapping PUCCH and PUSCH, and S0 is located at the end of the last symbol in the symbol group of the second signal below, Z'_(proc,CSI)^mux= (Z'+d)(2048+144)·κ2 -μ ·T cBefore the next UL symbol Z'_ref^mux begins, the UE does not need to provide a CSI report update for the nth triggered CSI report.

[0098] The symbol for the second signal: - The last symbol for aperiodic CSI-RS resources for channel measurements, and - The final symbol for the non-periodic CSI-IM used for interference measurements, and - The last symbol of the non-periodic NZP CSI-RS for interference measurements when the non-periodic CSI-RS is used for channel measurements for the nth triggered CSI report.

[0099] μ corresponds to the minimum SCS configuration in the SCS configuration of the PDCCH that schedules the PUSCH, the minimum SCS configuration of the aperiodic CSI-RS associated with the DCI format provided by the PDCCH that triggers the aperiodic CSI report, and the minimum SCS configuration of the overlapping PUCCH and PUSCH.

[0100] For μ=0 and 1, d=2; for μ=3, d=3; and for μ=3, d=4.

[0101] Z', κ and T c As defined above.

[0102] Z'_(proc,CSI)^mux can be understood as the minimum interval from the last symbol of the signal / channel for the measurement (e.g., CSI-RS) to the first symbol of the UL signal (e.g., PUSCH) (carrying the corresponding CSI report).

[0103] This operation can also be supported for μ=5 and / or μ=6 in the FR2-2 band, and for this purpose, the Z'_(proc,CSI)^mux formula needs to be defined for μ=5 and 6. In this disclosure, the d values ​​for μ=5 and 6 are proposed by one (or a combination of two or more) of the following methods.

[0104] 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, for μ=5, d=16, and for μ=6, d=32. This method maintains the complexity of the UE because when the UE processes a signal configured with a 480 / 960-kHz SCS, or when transmitting such a signal, the UE can have a processing / preparation timeline similar to that of a 120-kHz signal.

[0105] Method 2-2: The d value for μ=5 and / or μ=6 can be (equally) defined as the value obtained by scaling the d value for μ=3 by a factor of 4 or 8. That is, d=16 for μ=5 and 6, or d=32 for μ=5 and 6. This method can have the advantages of Method 2-1 in terms of timeline, and by fixing the d value for μ=5 and 6 to a single value, the additional time actually occurring due to "d" can also vary for each of μ=5 and 6.

[0106] 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 and 6. This method can be useful when Z for μ=5 and 6 is defined / configured to be sufficiently large. That is, since no separate d value is defined and the d values ​​for μ=3, 5 and 6 are defined the same, the impact on the specification is minimized, and the additional time actually occurring due to "d" can be applied differently for each μ.

[0107] Method 2-4: The value of d for μ=5 and / or μ=6 can be defined as 0. That is, d=0 for μ=5 and 6. This method may be useful when Z for μ=5 and 6 is defined / configured to be sufficiently large. In other words, since the value of Z for μ=5 and 6 is defined / configured to be sufficiently large, the advantages in terms of resource efficiency and latency can be obtained by minimizing the additional time actually incurred due to "d".

[0108] Method 2-5: The d value for μ=5 can be defined as the value obtained by adding 2 to the d value for μ=3 (i.e., d=6), and the d value for μ=6 can be defined as the value obtained by adding 3 (or 4) to the d value for μ=3 (i.e., d=7 or d=8). That is, for μ=5, d=6, and for μ=6, d=7 (or for μ=5, d=8). This method is based on the fact that the d value for μ=2 is a sign relative to the increments of μ=0 and 1, or the d value for μ=3 is a sign relative to the increments of μ=2. This method can also be useful when Z for μ=5 and 6 is defined / configured to be sufficiently large. That is, since the Z values ​​for μ=5 and 6 are defined / configured to be sufficiently large, advantages in resource efficiency and latency can be obtained by minimizing the additional time actually incurred due to "d".

[0109] Although the methods proposed in this disclosure are described for μ=5 and / or μ=6, they are not limited thereto. The proposed methods can be applied in the same way to parameter sets or SCS (i.e., 960 kHz) greater than μ=6. For example, for x>6, the proposed methods can be extended and applied as follows.

[0110] - The value of d for μ=x is defined as 0.

[0111] - The value of d for μ=x is defined as 4.

[0112] - The value of d for μ=x is defined as y times the value of d for μ=3. In this case, y is defined as 2^(x-3).

[0113] This disclosure is not limited to the transmission and reception of UL and / or DL ​​signals. For example, this disclosure can also be used for direct communication between UEs. Additionally, the term "BS" in this disclosure can include both relay nodes and base stations. For example, the operation of the BS described in this document can be performed by a base station, but the operation can also be performed by a relay node.

[0114] Obviously, each of the examples of the proposed methods can also be included as an implementation of this disclosure, and thus each example can be considered as a proposed method. Although the proposed methods described above can be implemented independently, some of the proposed methods can be combined (or merged) and implemented. Furthermore, it can be specified that information regarding whether the proposed methods are applied (or information regarding rules related to the proposed methods) is transmitted from the BS to the UE or from the transmitting UE to the receiving UE in predefined signals (e.g., physical layer signaling or higher layer signaling).

[0115] Implementation example

[0116] Figure 4 This is a flowchart illustrating methods for sending and receiving signals.

[0117] Reference Figure 4 The implementation performed by the UE may include: receiving DCI for scheduling PUSCH (S501), receiving CSI-RS in a non-periodic CSI-RS resource (S503), and sending a CSI report via PUSCH based on the measurement results of CSI-RS (S505).

[0118] Reference Figure 4 The implementation performed by the BS may include: sending DCI for scheduling PUSCH (S501), sending CSI-RS in non-periodic CSI-RS resources (S503), and receiving CSI reports via PUSCH based on CSI-RS measurement results (S505).

[0119] Apart from Figure 4 In addition to the operations described in Chapter 1, one or more operations can also be performed.

[0120] Referring to Section 1, the first symbol S0 of the earliest PUCCH or PUSCH in the overlapping PUCCH and PUSCH group in the time slot is not transmitted earlier than the first symbol after T_(proc,CSI)^mux (first processing time) starting from the last symbol of the received PDCCH, and not earlier than Z'_ref^mux (which is the first symbol) after Z'_(proc,CSI)^mux (second processing time) starting from the last symbol of the following three symbols.

[0121] - The last symbol for aperiodic CSI-RS resources for channel measurements.

[0122] - The last symbol for non-periodic CSI-IM used for interference measurements.

[0123] - When aperiodic CSI-RS is used for channel measurements for the nth triggered CSI report, the last symbol of the aperiodic NZP CSI-RS for interference measurements or all trigger sub-configurations.

[0124] Referring to the formulas related to the first and second processing times, 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 mentioned above, and depending on specific conditions, Z and Z' are selected as a pair from the values ​​in Tables 4 and 5.

[0125] The minimum SCS configuration based on PDCCH, the minimum SCS configuration for groups of overlapping PUSCH, and the minimum SCS configuration of CSI-RS associated with the DCI format of PUSCHs that include non-periodic CSI reports during scheduling determine the d value added to Z.

[0126] The minimum SCS configuration of the PDCCH based on the scheduling PUSCH, the minimum SCS configuration of the aperiodic CSI-RS associated with the DCI format provided by the PDCCH that triggers the aperiodic CSI report, and the minimum SCS configuration of the overlapping PUCCH and PUSCH determine the value of d to be added to Z'.

[0127] Conventionally, each d value is defined only up to the case where the minimum SCS value is 3. In this embodiment, for example referring to methods 1-3 and 2-3, for the case where the minimum SCS value is 5 or 6, both the d value for the first processing time (first value) and the d value for the second processing time (second value) can be set to the same as when the minimum SCS value is 3 (i.e., set to 4).

[0128] Although only the first and second values ​​based on methods 1-3 and 2-3 are illustrated, any combination of methods 1-1 to 1-5 and any combination of methods 2-1 to 2-5 is permissible.

[0129] In addition, based on the minimum SCS value being greater than 6, each d value associated with the first processing time and / or the second processing time can be determined (independently) by one of the methods when μ=x.

[0130] Besides about Figure 4 In addition to the operations described, they can also be combined and further executed via... Figures 1 to 3 The operation described and / or one or more of the operations described in Section 1.
