Background Art

[0002] Mobile communication systems were developed to provide voice services while ensuring user mobility. However, mobile communication systems have expanded beyond voice to include data services, and currently, due to the explosive increase in traffic, there is a shortage of resources, and users are demanding faster services, so a more advanced mobile communication system is desired.

[0061] System Overview

[0062] As more communication devices require larger communication capacities, there is a growing need for mobile broadband communication that is improved compared to existing radio access technologies (RATs). In addition, massive Machine Type Communications (MTC), which connects a large number of devices and things to provide various services anytime and anywhere, is also one of the major issues considered in next-generation communication. In addition to this, the design of communication systems considering services / terminals sensitive to reliability and latency is also being discussed. Thus, the introduction of next-generation RATs considering enhanced mobile broadband communication (eMBB), massive MTC (mMTC), Ultra-Reliable and Low Latency Communication (URLLC), etc. is being discussed, and in this disclosure, for convenience, this technology is referred to as NR. NR is an expression representing an example of 5G RAT.

[0063] The new RAT system including NR uses an OFDM transmission method or a transmission method similar thereto. The new RAT system may follow OFDM parameters different from those of LTE's OFDM parameters. Or, the new RAT system may directly follow the numerology of existing LTE / LTE-A but can support a larger system bandwidth (for example, 100 MHz). Or, one cell can also support multiple numerologies. That is, terminals operating with different numerologies may coexist within one cell.

[0064] Numerology corresponds to one subcarrier spacing in the frequency domain. Different numerologies can be defined by scaling the reference subcarrier spacing by an integer N.

[0065] FIG. 1 illustrates the structure of a wireless communication system to which the present disclosure is applicable.

[0066] Referring to FIG. 1, the NG-RAN is composed of gNBs that provide NG-RA (NG-Radio Access) user plane (i.e., new AS (access stratum) sublayer / PDCP (Packet Data Convergence Protocol) / RLC (Radio Link Control) / MAC / PHY) and control plane (RRC) protocol termination for UEs. The gNBs are interconnected via the Xn interface. The gNBs are also connected to the NGC (New Generation Core) via the NG interface. More specifically, the gNBs are connected to the AMF (Access and Mobility Management Function) via the N2 interface and to the UPF (User Plane Function) via the N3 interface.

[0067] FIG. 2 illustrates a frame structure in a wireless communication system to which the present disclosure is applicable.

[0068] The NR system can support a number of numerologies. Here, the numerology may be defined by the subcarrier spacing and the cyclic prefix (CP) overhead. At this time, a number of subcarrier spacings may be derived by scaling the basic (reference) subcarrier spacing by an integer N (or μ). Also, even assuming that a very low subcarrier spacing is not used at a very high carrier frequency, the numerology used may be selected independently of the frequency band. Also, in the NR system, various frame structures with a number of numerologies may be supported.

[0069] The OFDM numerologies and frame structures that can be considered in the NR system will be described below. A number of OFDM numerologies supported in the NR system may be defined as shown in Table 1 below.

[0070]

Table 1

[0071] NR supports a number of numerologies (or subcarrier spacings (SCS)) to support various 5G services. For example, when the SCS is 15 kHz, it supports a wide area in traditional cellular bands. When the SCS is 30 kHz / 60 kHz, it supports dense-urban areas, lower latency, and wider carrier bandwidths. When the SCS is 60 kHz or higher, it supports bandwidths greater than 24.25 GHz to overcome phase noise.

[0072] The NR frequency band is defined as two types (FR1, FR2) of frequency ranges. FR1 and FR2 may be configured as shown in Table 2 below. Also, FR2 can mean millimeter wave (mmW).

[0073]

Table 2

[0074] In relation to the frame structure in the NR system, the sizes of various fields in the time domain are multiples of the time unit of T c = 1 / (Δf max ·N f ). Here, Δf max = 480·10 3 Hz, and Nf is 4096. Downlink and uplink transmissions are in T f = 1 / (Δf max N f / 100)·T c = 10 ms intervals and are organized into radio frames. Here, each radio frame has T sf =(Δf max N f / 1000)·T c = 1 ms intervals and is composed of 10 subframes. In this case, there may be one set of frames for the uplink and one set of frames for the downlink. Also, the transmission at the uplink frame number i from the terminal must start T TA =(N TA +N TA,offset )T c before the start of the corresponding downlink frame at the terminal. For the subcarrier spacing configuration μ, a slot is numbered in increasing order of n s μ ∈ {0,..., N slot subframe,μ -1} within a subframe and in increasing order of n s,f μ ∈ {0,..., N slot frame,μ -1} within a radio frame. One slot is composed of N symb slot consecutive OFDM symbols, and N symb slot is determined by the CP. In a subframe, the start of slot n s μ is the OFDM symbol n s μ N symb slotis aligned in time with the start. Not all terminals can transmit and receive simultaneously, which means that not all OFDM symbols in a downlink slot or an uplink slot can be used.

[0075] Table 3 shows the number of OFDM symbols per slot (N symb slot ), the number of slots per radio frame (N slot frame,μ ), and the number of slots per subframe (N slot subframe,μ ) in the normal CP. Table 4 shows the number of OFDM symbols per slot, the number of slots per radio frame, and the number of slots per subframe in the extended CP.

[0076]

Table 3

[0077]

Table 4

[0078] Figure 2 shows an example when μ = 2 (SCS is 60 kHz). Referring to Table 3, one subframe can include 4 slots. The one subframe = {1, 2, 4} slots shown in Figure 2 is an example, and the number of slots that can be included in one subframe is defined as in Table 3 or Table 4. Also, a mini-slot can include 2, 4, or 7 symbols, or more or fewer symbols.

[0079] In relation to physical resources in the NR system, an antenna port, a resource grid, a resource element, a resource block, a carrier part, etc. may be considered. Hereinafter, the physical resources that can be considered in the NR system will be specifically described.

[0080] First, in relation to the antenna port, the antenna port is defined such that the channel through which the symbols on the antenna port are carried can be inferred from the channels through which other symbols on the same antenna port are carried. When the large-scale properties of the channels through which the symbols on one antenna port are carried can be analogized from the channels through which the symbols on other antenna ports are carried, it can be said that the two antenna ports are in a QC / QCL (quasi co-located or quasi co-location) relationship. Here, the large-scale properties include any one or more of delay spread, Doppler spread, frequency shift, average received power, and received timing.

[0081] FIG. 3 illustrates a resource grid in a wireless communication system to which the present disclosure is applicable.

[0082] Referring to FIG. 3, the resource grid is composed of N RB μ N sc RB sub-carriers, and it is exemplarily described that one sub-frame is composed of 14·2 μ OFDM symbols, but it is not limited thereto. In the NR system, the transmitted signal is N RBμ N sc RB One or more resource grids composed of subcarriers and 2 μ N symb (μ) are described by the OFDM symbols of. Here, N RB μ ≤ N RB max,μ is. The said N RB max,μ represents the maximum transmission bandwidth, which may vary not only in numerology but also between the uplink and the downlink. In this case, one resource grid may be set separately for each of μ and antenna port p. Each element of the resource grid for μ and antenna port p is called a resource element and is uniquely identified by the index pair JPEG2025516180000006.jpg7169. Here, k = 0,..., N RB μ N sc RB −1 is the index in the frequency domain, and JPEG2025516180000007.jpg7169 represents the position of the symbol within the subframe. When indicating a resource element in a slot, the index pair (k, l) is used. Here, l = 0,..., N symb μ −1. The resource element JPEG2025516180000008.jpg7169 for μ and antenna port p is a complex value corresponding to JPEG2025516180000009.jpg8169. If there is no risk of confusion or a specific antenna port or numerology is not specified, the indices p and μ may be dropped, and as a result, the complex value is JPEG2025516180000010.jpg9169 or It can be JPEG2025516180000011.jpg7169. Also, a resource block (RB) is defined as N sc RB = 12 consecutive subcarriers in the frequency domain.

[0083] Point A serves as the common reference point of the resource block grid and is obtained as follows.

[0084] - offsetToPointA for the primary cell (PCell) downlink indicates the frequency offset between the lowest subcarrier of the lowest resource block that overlaps with the SS / PBCH block used by the terminal for initial cell selection and point A. It is expressed in resource block units assuming a 15 kHz subcarrier spacing for FR1 and a 60 kHz subcarrier spacing for FR2.

[0085] - absoluteFrequencyPointA indicates the frequency - position of point A expressed as in the absolute radio - frequency channel number (ARFCN).

[0086] The common resource block is numbered upward from 0 in the frequency domain for the subcarrier spacing setting μ. The center of subcarrier 0 of common resource block 0 for the subcarrier spacing setting μ coincides with 'point A'. The relationship between the common resource block number n CRB μ in the frequency domain and the resource element (k, l) for the subcarrier spacing setting μ is given as in Equation 1 below.

[0087]

Equation

[0088] In Equation 1, k is defined relative to Point A such that k = 0 corresponds to the sub-carrier centered at Point A. The physical resource block is numbered from 0 to N BWP,i size,μ -1 within the bandwidth part (BWP), and i is the number of the BWP. In BWP i, the relationship between the physical resource block n PRB and the common resource block n CRB is given by Equation 2 below.

[0089]

Number

[0090] N BWP,i start,μ is the common resource block where the BWP starts relative to the common resource block 0.

[0091] FIG. 4 illustrates a physical resource block in a wireless communication system to which the present disclosure is applicable. And FIG. 5 illustrates a slot structure in a wireless communication system to which the present disclosure is applicable.

[0092] Referring to FIGS. 4 and 5, a slot includes a plurality of symbols in the time domain. For example, in the case of normal CP, one slot includes 7 symbols, while in the case of extended CP, one slot includes 6 symbols.

[0093] The carrier wave includes a plurality of sub-carrier waves in the frequency domain. An RB (Resource Block) is defined as a plurality (e.g., 12) of consecutive sub-carrier waves in the frequency domain. A BWP (Bandwidth Part) is defined as a plurality of consecutive (physical) resource blocks in the frequency domain and can correspond to one numerology (e.g., SCS, CP length, etc.). A carrier wave can include up to N (e.g., 5) BWPs. Data communication is performed on the activated BWP, and only one BWP may be activated for one terminal. Each element in the resource grid is called a resource element (RE:Resource Element), and one complex symbol may be mapped to it.

[0094] The NR system may support up to 400 MHz per component carrier (CC:Component Carrier). If a terminal operating in such a wideband CC always operates with the radio frequency (RF) chip for the entire CC turned on, the terminal battery consumption may increase. Alternatively, considering various use cases (e.g., eMBB, URLLC, Mmtc, V2X, etc.) operating within one wideband CC, different numerologies (e.g., sub-carrier spacing, etc.) may be supported for different frequency bands within the CC. Alternatively, the capabilities of terminals may vary with respect to the maximum bandwidth. Considering this, the base station may instruct the terminal to operate only on a part of the bandwidth instead of the entire bandwidth of the wideband CC, and this part of the bandwidth is defined as the bandwidth part (BWP) for convenience. A BWP may be composed of consecutive RBs on the frequency axis and can correspond to one numerology (e.g., sub-carrier spacing, CP length, slot / minislot interval).

[0095] On one hand, the base station can configure multiple BWPs within one CC configured for a terminal. For example, in a PDCCH monitoring slot, a BWP that occupies a relatively small frequency region can be configured, and the PDSCH indicated by the PDCCH may be scheduled on a larger BWP than that. Alternatively, when UEs concentrate on a specific BWP, other BWPs may be configured for some terminals for load balancing. Alternatively, considering frequency domain inter-cell interference cancellation between adjacent cells, etc., a part of the spectrum of the entire bandwidth can be excluded, and both BWPs can be configured within the same slot. That is, the base station can configure at least one DL / UL BWP for a terminal associated with a wideband CC. The base station can activate at least one of the DL / UL BWPs configured at a specific time (by means of L1 signaling or MAC CE (Control Element) or RRC signaling, etc.). Also, the base station can instruct switching to other configured DL / UL BWPs (by means of L1 signaling or MAC CE or RRC signaling, etc.). Or, when the timer value expires based on a timer, it may switch to a defined DL / UL BWP. At this time, the activated DL / UL BWP is defined as the active DL / UL BWP. However, during the initial access process of the terminal or in situations such as before the RRC connection is set up, the terminal may not be able to receive the configuration for the DL / UL BWP. Therefore, the DL / UL BWP assumed by the terminal in such situations is defined as the initial active DL / UL BWP.

[0096] FIG. 6 illustrates physical channels used in a wireless communication system to which the present disclosure is applicable and a general signal transmission / reception method using them.

[0097] In a wireless communication system, a terminal receives information from a base station on the downlink, and the terminal transmits information to the base station on the uplink. The information transmitted and received between the base station and the terminal includes data and various control information, and there are various physical channels depending on the type / usage of the information they transmit and receive.

[0098] When the terminal is powered on or newly enters a cell, it performs an initial cell search operation such as synchronizing with the base station (S601). For this purpose, the terminal receives the primary synchronization signal (PSS) and the secondary synchronization signal (SSS) from the base station to synchronize with the base station and can obtain information such as a cell identifier (ID). After that, the terminal can receive the physical broadcast channel (PBCH) from the base station to obtain in-cell broadcast information. On the other hand, the terminal can receive the downlink reference signal (DL RS) in the initial cell search stage to check the downlink channel state.

[0099] After completing the initial cell search, the terminal can receive the physical downlink shared channel (PDSCH) based on the physical downlink control channel (PDCCH) and the information carried on the PDCCH, and obtain more specific system information (S602).

[0100] On one hand, when the terminal first connects to the base station or there is no radio resource for signal transmission, the terminal can perform a random access procedure (RACH) with the base station (steps S603 to S606). For this purpose, the terminal transmits a specific sequence as a preamble on the physical random access channel (PRACH) (S603 and S605), and can receive a response message for the preamble on the PDCCH and the corresponding PDSCH (S604 and S606). In the case of contention-based RACH, furthermore, a contention resolution procedure can be performed.

[0101] After performing the above-described procedure, the terminal can then perform PDCCH / PDSCH reception (S607) and physical uplink shared channel (PUSCH) / physical uplink control channel (PUCCH) transmission (S608) as a general uplink / downlink signal transmission procedure. In particular, the terminal receives downlink control information (DCI) on the PDCCH. Here, the DCI includes control information such as resource allocation information for the terminal, and the formats are different from each other depending on the purpose of use.

[0102] On the other hand, the control information that the terminal transmits to the base station on the uplink or that the terminal receives from the base station includes downlink / uplink ACK / NACK (Acknowledgement / Non-Acknowledgement) signals, CQI (Channel Quality Indicator), PMI (Precoding Matrix Indicator), RI (Rank Indicator), etc. In the 3GPP LTE system, the terminal can transmit control information such as the above-described CQI / PMI / RI on the PUSCH and / or PUCCH.

[0103] Table 5 shows an example of DCI format in the NR system.

[0105] Referring to Table 5, DCI formats 0_0, 0_1, and 0_2 can include resource information related to PUSCH scheduling (e.g., UL / SUL (Supplementary UL), frequency resource allocation, time resource allocation, frequency hopping, etc.), transport block (TB) related information (e.g., MCS (Modulation Coding and Scheme), NDI (New Data Indicator), RV (Redundancy Version), etc.), HARQ (Hybrid-Automatic Repeat and request) related information (e.g., process number, DAI (Downlink Assignment Index), PDSCH-HARQ feedback timing, etc.), multi-antenna related information (e.g., DMRS sequence initialization information, antenna port, CSI request, etc.), and power control information (e.g., PUSCH power control, etc.). The control information included in each DCI format may be defined in advance.

[0106] DCI format 0_0 is used for PUSCH scheduling in one cell. The information included in DCI format 0_0 is transmitted after being CRC (cyclic redundancy check) scrambled by C-RNTI (Cell RNTI: Cell Radio Network Temporary Identifier) or CS-RNTI (Configured Scheduling RNTI) or MCS-C-RNTI (Modulation Coding Scheme Cell RNTI).

[0107] DCI format 0_1 is used to schedule one or more PUSCHs in one cell or to instruct the terminal with downlink feedback information of a configured grant (CG). The information included in DCI format 0_1 is transmitted after being CRC scrambled by a C-RNTI or a CS-RNTI or an SP-CSI-RNTI (Semi-Persistent CSI RNTI) or an MCS-C-RNTI.

[0108] DCI format 0_2 is used to schedule PUSCH in one cell. The information included in DCI format 0_2 is transmitted after being CRC scrambled by a C-RNTI or a CS-RNTI or an SP-CSI-RNTI or an MCS-C-RNTI.

[0109] Next, DCI formats 1_0, 1_1, and 1_2 can include resource information related to PDSCH scheduling (e.g., frequency resource allocation, time resource allocation, VRB (virtual resource block)-PRB (physical resource block) mapping, etc.), transmission block (TB) related information (e.g., MCS, NDI, RV, etc.), HARQ related information (e.g., process number, DAI, PDSCH-HARQ feedback timing, etc.), multiple antenna related information (e.g., antenna port, TCI (transmission configuration indicator), SRS (sounding reference signal) request, etc.), PUCCH related information (e.g., PUCCH power control, PUCCH resource indicator, etc.). The control information included in each DCI format may be defined in advance.

[0110] DCI format 1_0 is used for scheduling the PDSCH in one DL cell. The information contained in DCI format 1_0 is transmitted after being CRC scrambled by C-RNTI or CS-RNTI or MCS-C-RNTI.

[0111] DCI format 1_1 is used for scheduling the PDSCH in one cell. The information contained in DCI format 1_1 is transmitted after being CRC scrambled by C-RNTI or CS-RNTI or MCS-C-RNTI.

[0112] DCI format 1_2 is used for scheduling the PDSCH in one cell. The information contained in DCI format 1_2 is transmitted after being CRC scrambled by C-RNTI or CS-RNTI or MCS-C-RNTI.

[0113] Quasi-Co Location (QCL)

[0114] An antenna port is defined such that the channel on which the symbols on the antenna port are carried can be inferred from the channel on which other symbols on the same antenna port are carried. When the characteristics of the channel on which the symbols on one antenna port are carried can be analogized from the channel on which the symbols on other antenna ports are carried, it can be said that the two antenna ports are in a QC / QCL (quasi co-located or quasi co-location) relationship.

[0115] Here, the channel characteristics include one or more of delay spread, Doppler spread, frequency / Doppler shift, average received power, received timing / average delay, and spatial Rx parameter. Here, the spatial Rx parameter means a spatial (reception) channel characteristic parameter such as the angle of arrival.

[0116] The terminal may be configured by a list of up to M TCI-State settings within the higher layer parameter PDSCH-Config in order to decode the PDSCH by means of a detected PDCCH having the DCI intended for the terminal and a given serving cell. The M depends on the UE capability.

[0117] Each TCI-State includes parameters for setting a quasi co-location relationship between one or two DL reference signals and the DM-RS ports of the PDSCH.

[0118] The quasi co-location relationship is set by the higher layer parameter qcl-Type1 for the first DL RS and qcl-Type 2 (if set) for the second DL RS. In the case of two DL RSs, the QCL type is not the same regardless of whether the reference is the same DL RS or different DL RSs from each other.

[0119] The quasi co-location type corresponding to each DL RS is given by the higher layer parameter qcl-Type of QCL-Info and can take one of the following values:

[0120] - "QCL-TypeA": {Doppler shift, Doppler spread, average delay, delay spread}

[0121] - "QCL-TypeB": {Doppler shift, Doppler spread}

[0122] - "QCL-TypeC": {Doppler shift, average delay}

[0123] - "QCL-TypeD": {Spatial Rx parameter}

[0124] For example, when the target antenna port is a specific NZP CSI-RS, the NZP CSI-RS antenna port may be indicated / set to be QCL with a specific TRS from the QCL-Type A perspective and with a specific SSB from the QCL-Type D perspective. A terminal receiving such an indication / setting can receive the NZP CSI-RS using the Doppler and delay values measured at the QCL-TypeA TRS, and apply the reception beam used for QCL-TypeD SSB reception to the NZP CSI-RS reception.

[0125] The UE can receive an activation command by MAC CE signaling used to map up to 8 TCI states to the code points of the DCI field "Transmission Configuration Indication".

[0126] Configured Grant on Uplink

[0127] The configured grant for PUSCH is distinguished into CG Type 1 and CG Type 2.

[0128] For CG Type 1, resource allocation is completely set or released using RRC signaling. When CG Type 1 is set, a resource set for the terminal to periodically transmit PUSCH is allocated, and the PDCCH is requested only when retransmission is required. CG Type 1 PUSCH transmission is semi-statically set to operate when receiving the upper layer parameter configuredGrantConfig including rrc-ConfiguredUplinkGrant without detecting a UL grant in the DCI. The terminal can perform PUSCH transmission according to the set CG Type 1 until additional RRC signaling is reconfigured for the terminal.

[0129] For CG Type 2, resource allocation is partially set using RRC signaling and activation / deactivation is indicated using PDCCH transmission. Since the PDCCH also provides time and frequency resource allocation, the resource allocation can change each time it is activated. CG Type 2 PUSCH transmission is semi-persistently scheduled by a UL grant in a valid activation DCI after receiving the upper layer parameter configuredGrantConfig that does not include rrc-ConfiguredUplinkGrant.

[0130] One or more CG settings of CG Type 1 and / or CG Type 2 may be simultaneously activated on the activated BWP of the serving cell.

[0131] In PUSCH transmission corresponding to CG Type 1 or CG Type 2, the parameters for PUSCH transmission may be provided by configuredGrantConfig.

[0132] Table 6 shows an example of the configuredGrantConfig IE. The configuredGrantConfig IE is used to configure uplink transmission without a dynamic grant by DCI. In fact, the uplink grant may be configured by RRC (CG Type 1) or provided by PDCCH (using CS-RNTI) (CG Type 2). Multiple CG settings may be configured within one BWP of the serving cell.

[0133]

Table 6-1

Table 6-2

[0134] In Table 6, periodicity represents the period for uplink CG transmission, which means the time interval between consecutive continuous resource allocations. periodicityExt is used to calculate the period of the uplink CG. If this parameter does not exist, periodicity is ignored. The uplink CG periods are different from each other for the values supported by the configured subcarrier spacing.

[0135] nrofHARQ-Processes represents the number of HARQ processes configured for the uplink CG. In the case of dynamic resource allocation, the HARQ process identifier is specified within the DCI associated with each resource allocation. However, for the uplink CG, the HARQ process identifier is determined based on the nrofHARQ-Processes value and the periodicity value.

[0136] repK represents the number of repetitions. That is, it indicates the repetition level for each PUSCH transmission. repK may have one value from {1, 2, 4, 8}. In the case of CG Type 1, when the pusch-RepTypeIndicator in rrc-ConfiguredUplinkGrant indicates "pusch-RepTypeB", PUSCH repetition type B is applied; otherwise, PUSCH repetition type A is applied. In the case of CG Type 2, the PUSCH repetition type is determined by the UL grant in the DCI. The terminal repeats and transmits the uplink TB the set number of times according to the set PUSCH repetition type A or B.

[0137] repK-RV represents the redundancy version sequence. repK-RV is set when repetition is used (i.e., when repK is set to one value from {2, 4, 8}).

[0138] resourceAllocation represents the setting of bitmap-based resource allocation type 0 or resource indication value (RIV)-based resource allocation type 1.

[0139] mcs-Table indicates the MCS table used by the terminal for PUSCH for which transform precoding is not used, and mcs-TableTransformPrecoder indicates the MCS table used by the terminal for PUSCH for which transform precoding is used. transformPrecoder indicates whether transform precoding is enabled for PUSCH.

[0140] The rrc-ConfiguredUplinkGrant is a configuration for CG Type 1 transmission. If this field does not exist, the terminal uses the UL grant configured by DCI with CS-RNTI (i.e., CG Type 2). The timeDomainAllocation indicates the start symbol and length of the PUSCH and the PUSCH mapping type. The timeDomainOffset represents the offset related to the reference SFN (system frame number) indicated by the timeReferenceSFN. The timeReferenceSFN indicates the SFN used to determine the resource offset in the time domain. The terminal uses the SFN closest to the number indicated before receiving the configured grant setting, and if this field does not exist, the reference SFN is 0.

[0141] After the uplink grant is configured for CG Type 1, the MAC entity sequentially considers the occurrence of the Nth (N≥0) uplink grant within the symbol according to Equation 3 below. That is, when CG Type 1 is used, the CG PUSCH may be transmitted in a transmission occasion / opportunity that satisfies Equation 3 below.

[0142]

Number

[0143] Also, after the uplink grant is configured for CG Type 2, the MAC entity sequentially considers the occurrence of the Nth (N≥0) uplink grant within the symbol according to Equation 4 below. That is, when CG Type 2 is used, the CG PUSCH may be transmitted in a transmission occasion / opportunity that satisfies Equation 4 below.

[0144]

Number

[0145] In Equation 3 and Equation 4, numberOfSlotsPerFrame represents the number of consecutive slots per frame, and numberOfSymbolsPerSlot represents the number of consecutive symbols per slot.

[0146] Also, timeReferenceSFN is used for determining the offset of resources in the time domain, and the UE can use the SFN closest to the number indicated before receiving the configured CG. timeDomainOffset represents the offset related to the reference SFN indicated by timeReferenceSFN. periodicity represents the period of UL transmission for CG Type 1. timeReferenceSFN, timeDomainOffset, and periodicity may be set by configuredGrantConfig (see Table 6). Also, S corresponds to the start symbol deduced from timeDomainAllocation (see Table 6), and N is an integer value corresponding to the Nth transmission occasion / opportunity.

[0147] Also, SFN start time 、slot start time and symbol start time respectively represent the SFN, slot, and symbol of the first transmission occasion / opportunity of the PUSCH for which the CG is (re)initialized (i.e., in the PUSCH transmission generated by the resource allocation within the active PDCCH).

[0148] On one hand, in the case of dynamic resource allocation on PDCCH, the HARQ process identifier (HARQ process ID) is specified within the DCI. In contrast, in the case of CG, since the DCI is not received before each PUSCH transmission, the HARQ process is calculated by the following Equation 5 or Equation 6. The base station can set the number of HARQ processes (e.g., nrofHARQ - Processes) and the offset (e.g., harq - ProcID - Offset2) used to derive the HARQ process ID.

[0149] When the offset (e.g., harq - ProcID - Offset2) used to derive the HARQ process ID and the re - transmission timer (cg - RetransmissionTimer) are not set, the UE derives the HARQ process ID associated with the slot at which the uplink transmission starts from the following Equation 5. Alternatively, when the offset (e.g., harq - ProcID - Offset2) used to derive the HARQ process ID is set, the UE derives the HARQ process ID associated with the slot at which the uplink transmission starts from the following Equation 6.

[0150]

Equation

[0151]

Equation

[0152] In Equation 5 and Equation 6, nrofHARQ - Processes defines the number of uplink HARQ processes and may have values from 1 to 16 (see Table 6). nrofHARQ - Processes is used to identify the HARQ process ID for a specific PUSCH transmission.

[0153] Also, in Equation 5 and Equation 6, CURRENT_symbol = (SFN × numberOfSlotsPerFrame × numberOfSymbolsPerSlot + slot number in the frame × numberOfSymbolsPerSlot + symbol number in the slot). numberOfSlotsPerFrame and numberOfSymbolsPerSlot respectively represent the number of consecutive slots per frame and the number of consecutive symbols per slot.

[0154] On the other hand, in Table 6, configuredGrantTimer indicates the initial value of the CG timer as a multiple of periodicity. That is, configuredGrantTimer defines the duration (period) for which the UE waits for a retransmission request after transmitting an uplink packet. The CG timer is driven independently for each HARQ process.

[0155] To describe this more specifically, the MAC entity includes a HARQ entity for each serving cell having a configured uplink, which maintains a plurality of parallel HARQ processes. The number of parallel HARQ processes per HARQ entity is determined by the standard specification. Each HARQ process supports one TB. Each HARQ process is associated with one HARQ process identifier (ID). When one TB is repeated in multiple CG PUSCHs (i.e., multiple CG PUSCH TOs), the same HARQ process may be used for the repeated CG PUSCHs.

[0156] For an uplink grant, the HARQ entity identifies the HARQ process associated with the grant. For the identified HARQ process, if the uplink grant is the uplink grant set for the HARQ process and is used for the first transmission for the set uplink grant, the HARQ entity can start a CG timer (i.e., configuredGrantTimer) by means of an initial CG PUSCH transmission for the HARQ process identified by the said Equation 5 or Equation 6. Here, the CG timer (i.e., configuredGrantTimer) may be started from the start of the first symbol of the initial CG PUSCH transmission.

[0157] When the CG timer expires, the UE can assume a positive acknowledgement. When this timer expires (i.e., no retransmission request is received until the timer expires), the UE assumes a positive acknowlegement. Thereby, the UE can subsequently transmit new uplink data using the same HARQ process.

[0158] Such a CG timer needs to be set long enough to guarantee the time for the base station to receive uplink packets and schedule retransmission requests. However, if this CG timer is set too long, the UE cannot reuse the HARQ process for new transmissions until a positive acknowlegement for a previous transmission is assumed, and delays may occur.

[0159] Method for Transmitting and Receiving Physical Uplink Shared Channel (PUSCH) with Configured Grant (CG)

[0160] In the present disclosure, when video information of an extended reality (XR) service is transmitted using pre-configured resources such as a configured grant (CG) of an NR wireless communication system, a method is proposed to reduce power consumption and improve the efficiency of wireless resources while ensuring the availability and reliability of the transmission resources.

[0161] In NR, one or more CG PUSCHs can be configured for a UE for periodic transmission and reception, or for low latency and PDCCH overhead. Each CG configuration may repeat the configured / indicated resources at a period. That is, the initially configured / indicated resource allocation is repeated at the configured period, and the UE can perform uplink transmission using the resource without another PDCCH reception process.

[0162] On the other hand, the types of data that can occur in XR are diverse. Among such data, the transmission of UE sensor and location information and video data, which are generally reported with a specific period, is considered to be transmitted and received using CG resources. Such data may not always have a constant traffic arrival time and may have jitter due to reasons such as video encoding time, sensor measurement time, upper layer operations, or routing changes in the transmitted network.

[0163] Considering jitter, etc., if resources are allocated at a position sufficiently far in time from the expected traffic arrival time, the availability of the resources can be guaranteed, but a delay time may occur. Conversely, if CG resources with a fixed period are allocated to the expected data generation time, a larger delay time may occur due to the waiting time until the next available resource when jitter occurs.

[0164] In addition, since certain data is generated based on events, it is impossible to accurately grasp the actual time of data generation. However, in order to reduce the delay time caused by scheduling, it is considered to use CG resources for such data as well. In this case, a method of allocating a sufficiently large amount of resources in a short cycle in preparation for the generation of data, and having the UE or the base station selectively use such resources and skip other resources that are not actually used has been discussed conventionally. However, in order to use the method of skipping transmission and reception, it is necessary to consider a response signal for determining the presence or absence of reception and transmission between the UE and the base station. If the UE sends a response signal even for transmissions it has not received, the base station needs to always prepare the resources for which the UE will send the response signal. And, considering that such resources are set to be sufficiently large within the radio resources as the basis of the skip method, it can act as a large uplink burden. Also, considering that such resources can be multiplexed among UEs, the burden on the uplink resources should be considered more importantly.

[0165] Since ensuring a low delay time is essential for the quality of XR services, it is necessary to consider a method for minimizing the impact on the delay time while reducing the influence of jitter. In the present disclosure, in order to solve such problems, a method is described in which a part of a plurality of CG resources set between the UE and the base station is selectively used, and the response to the CG resources thus used is simplified and transmitted to a predetermined position.

[0166] A group of pictures (GOP) in video coding may include the following types of pictures.

[0167] An I picture or I frame (i.e., an intra-coded picture) (or also referred to as a key frame or i-frame) is a picture coded independently of all other pictures. Each GOP starts with a picture of this type (in decoding order).

[0168] A P picture or P frame (i.e., a predictive-coded picture) contains motion-compensated difference information relative to a previously decoded picture. For example, in previous designs such as H.262 / MPEG-2 and H.263, each P picture can reference only one picture, which must precede the P picture in both display order and decoding order and must be an I or P picture. Such constraints do not apply to the new standards H.264 / MPEG-4 AVC and HEVC.

[0169] A B picture or B frame (a bipredictive-coded picture) contains motion-compensated difference information relative to previously decoded pictures. For example, in previous designs such as MPEG-1 and H.262 / MPEG-2, each B picture can reference only two pictures, one that precedes the B picture in display order and one that follows the B picture in display order, and all referenced pictures must be I or P pictures. Such constraints do not apply to the new standards H.264 / MPEG-4 AVC and HEVC.

[0170] A D picture or D frame (a direct-coded picture) serves as a fast access display of a picture for loss robustness or fast-forward. D pictures are used only in MPEG-1 video.

[0171] Figure 7 illustrates the structure / pattern of a group of pictures.

[0172] Referring to Figure 7, an I-frame indicates the start of a GOP. Subsequently, a plurality of P and B frames follow. In previous designs, the allowed ordering and reference structures are relatively restricted.

[0173] The GOP structure is often referred to by two numbers, for example, M = 3, N = 12. The first number (M) represents the distance between two anchor frames (I or P). The second number (N) is the GOP size that indicates the distance between two full images (I-frames). For example, when M = 3, N = 12, the GOP structure is IBBPBBPBBPBBI. Instead of the M parameter, the maximum number of B frames between two consecutive anchor frames can also be used.

[0174] For example, in a sequence with the pattern IBBBBPBBBBPBBBBBI, the GOP size (N value) is 15 (the length between two I-frames), and the distance between both anchor frames (M value) is 5 (the length between an I-frame and a P-frame or the length between two consecutive P-frames).

[0175] An I-frame contains a full image and does not require additional information to reconstruct it. Generally, the encoder uses a GOP structure such that each I-frame becomes a "clean random access point". Therefore, decoding can start cleanly at an I-frame, and all errors within the GOP structure are corrected after processing the correct I-frame.

[0176] Hereinafter, in the present disclosure, a method proposed based on uplink CG radio resources set semi-statically will be described. This is for the convenience of explanation and the method proposed in the present disclosure is not limited thereto. Therefore, those skilled in the art can understand that the method proposed in the present disclosure can also be extended and applied to the radio resources allocated by dynamic scheduling received by the UE. For example, a method for determining one HARQ-ACK timing for a plurality of downlink radio resources allocated to the UE may be applied regardless of whether it is SPS PDSCH or PDSCH indicated by dynamic scheduling. Also, when a plurality of radio resources are not set semi-statically but are set by dynamic indication, for example, when a plurality of radio resources are set at once by DCI, the method proposed in the present disclosure may be applied. Therefore, the method proposed in the present disclosure may be applied to any type of transmission and reception method expected by the base station and the terminal as long as the principle of the proposed method is not violated without other explanations. Hereinafter, in the present disclosure, for the convenience of explanation, semi-persistent scheduling (SPS) can be used as a general concept collectively referring to radio resources set semi-statically (for example, DL / UL SPS, CG).

[0177] Also, in the present disclosure, a transmission occasion (TO) means radio resources set for CG use (for example, CG PUSCH). The entity that performs transmission in the transmission occasion (that is, the base station in the downlink and the UE in the uplink) can attempt to transmit in the TO, and the receiver (that is, the UE in the downlink and the base station in the uplink) can attempt to receive expecting transmission in each TO.

[0178] Hereinafter, in the present disclosure, for the purpose of explaining the principle of the proposed method, an example will be given based on the NR system for explanation. However, the proposed method does not specify or limit the NR transmission / reception mode unless otherwise specified. Also, in the following present disclosure, for the purpose of explaining the principle of the proposed method, an example will be given based on the characteristics and structure of the XR service for explanation. However, the proposed method does not specify or limit the support for the XR service unless otherwise specified. Therefore, the method proposed in the present disclosure may be applied to any wireless communication transmission / reception structure and service as long as the principle of the proposed method is not violated even without specific explanation.

[0179] Hereinafter, in the present disclosure, a method of connecting / associating a plurality of CG settings for a plurality of CG resources set between a UE and a base station in case of a GOP pattern and jitter occurring, and / or a method of activating / transmitting a second CG transmission by a first connected / associated CG transmission are proposed. Also, in the present disclosure, a method of adjusting the transmission timing of the CG PUSCH or activating a deactivated CG in consideration of the jitter of the uplink traffic is proposed. Thereby, it is possible to quickly respond to the uplink VR / virtual reality (VR) / extended reality (XR) video traffic due to the movement of the UE, and to perform optimized CG resource allocation in consideration of the jitter of the uplink video traffic.

[0180] Therefore, the method proposed in the present disclosure may include a method for a base station to allocate CG radio resources to a UE and a method for receiving and transmitting CG resources. Also, the method proposed in the present disclosure may include a method of transmitting a HARQ-ACK response to the CG PUSCH reception result, and then a method of receiving the retransmission DCI of the base station by the PDCCH. Also, the method proposed in the present disclosure may include a process in which the UE transmits a signal and a channel for notifying its own capability and / or service requirement conditions, and the base station receives it.

[0181] The method proposed in this disclosure may be applied by selecting some of the following methods. In addition, each method proposed in this disclosure can operate independently without other combinations, or one or more methods may be combined and associated to operate. Some terms, symbols, orders, etc. used for the description of the methods proposed in this disclosure may be replaced by other terms, symbols, orders, etc. as long as the principle of the invention is maintained.

[0182] In this disclosure, the following CG settings, activation / deactivation, transmission / reception operations, etc. can be supported. That is, the following CG settings, activation / deactivation, transmission / reception operations, etc. may be incorporated into the method proposed in this disclosure.

[0183] FIG. 8 illustrates a plurality of configured grant settings according to an embodiment of the present disclosure.

[0184] - A plurality of CGs (for example, when there are two CGs, CG1 and CG2) may be set as one CG group by a CG setting in which they are interconnected / associated, and CG1 can be set as the primary CG and CG2 as the secondary CG. Here, the secondary CG may be a CG that is activated or received by the transmission of the primary CG. For example, the CG setting for CG PUSCH 1 in FIG. 8 is a primary CG setting, the CG setting for CG PUSCH 2 is a secondary CG setting, and the two CG settings may be set as one CG group.

[0185] - The primary CG and the secondary CG may be set with different CG configuration indexes. Or, the primary CG and the secondary CG may be set with the same CG configuration index, but may be distinguished by an RRC message, a MAC CE, or a DCI into a primary / secondary CG indicator or different sub-indexes.

[0186] i) When the DCI instructs CG1 and also instructs activation, the UE can activate CG2 either simultaneously with the activation of CG1 or after a certain period of time.

[0187] ii) Or, when the DCI instructs both CG1 and CG2 and also instructs activation, the UE can activate CG2 either simultaneously with the activation of CG1 or after a certain period of time. For example, in FIG. 8, a case is exemplified where activation is instructed for both the CG setting for CG PUSCH 1 and the CG setting for CG PUSCH 2 by one DCI. Also, a case is exemplified where the CG setting for CG PUSCH 1 and the CG setting for CG PUSCH 2 are activated simultaneously.

[0188] Here, the DCI may include all different CG setting indexes for CG1 and CG2.

[0189] Or, the DCI can include the CG setting index for CG1 and can instruct a secondary CG indicator.

[0190] Or, the DCI can include the CG setting index for CG2 and can instruct a primary CG indicator.

[0191] Or, the DCI can include the CG setting index for CG1 or CG2 and may include a sub-index for CG2 or CG1.

[0192] Or, the DCI can instruct a common CG setting index for CG1 and CG2. For example, among the HARQ process identifier (ID: identity) values that instruct the CG setting index, values in the range of 1 to 8 are set as the conventional CG setting index (i.e., for instructing a single CG setting), and HARQ process ID values exceeding 8 may be set as the CG setting index for simultaneously instructing a plurality of concatenated CGs.

[0193] Alternatively, the DCI may include all different CG configuration sub-indices for CG1 and CG2.

[0194] - The base station can set different video frame types (e.g., I-frame and P-frame) to different logical channels. Thereby, depending on the value of the logical channel identifier (LCID) field included in the sub-header of the uplink MAC protocol data unit (i.e., transport block (TB)), the UE can indicate that the data is for different video frames. Here, the base station can be set to map different logical channels for different video frame types to different CGs. Here, CG1 and CG2 may be mapped to the same or different logical channels.

[0195] For example, referring to FIG. 8, different logical channels may be set / assigned for the I-frame and the P-frame. Also, the logical channel for the I-frame may be mapped to the CG for CG PUSCH 1, and the logical channel for the P-frame may be mapped to the CG for CG PUSCH 2.

[0196] - The activation or transmission / reception of CG2 may be determined by the activation or presence / absence of transmission / reception of CG1. Here, the activation of CG2 may be set to occur simultaneously with or after the activation of CG1.

[0197] - The UE can expect that CG2 PUSCH transmission occurs only after CG1 PUSCH transmission. Therefore, the CG2 PUSCH transmission in the next period may be determined by the presence / absence of CG1 PUSCH transmission.

[0198] - When CG1 PUSCH and CG2 PUSCH are transmitted / assigned by TDM or FDM in the same period or a partially overlapping period, when transmitting CG1 PUSCH, the UE can determine whether the CG2 PUSCH resource is not valid or skip the CG2 PUSCH transmission. Alternatively, the UE can deactivate CG2 or deactivate the activated CG2. For example, as shown in FIG. 8, the CG setting for CG PUSCH 1 can be set in a period that is N times (N is a natural number) of 16 ms or 17 ms, and the CG setting for CG PUSCH 2 can be set in a period of 16 ms or 17 ms. And N CG settings for CG PUSCH 2 within one period of the CG setting for CG PUSCH 1 may overlap. That is, as shown in FIG. 8, in the first period of CG PUSCH 2, CG PUSCH 2 and CG PUSCH 1 may be assigned by TDM or FDM. In this case, it may be determined that the resource of CG PUSCH 2 (PUSCH 2 carrying TB2 for the I frame in FIG. 8) is not valid, or it may be determined to skip the transmission of CG PUSCH 2.

[0199] - When CG1 PUSCH and CG2 PUSCH are transmitted / assigned by TDM or FDM in the same slot, or when the CG1 PUSCH and CG2 PUSCH resources overlap, the UE gives priority to CG1 PUSCH reception regardless of the CG setting indexes of CG1 and CG2. That is, in this case, the UE can skip the CG2 PUSCH resource transmission and transmit the CG1 PUSCH resource. For example, as shown in FIG. 8, CG PUSCH 2 (PUSCH 2 carrying TB2 for the I frame in FIG. 8) can be skipped and only the CG PUSCH 1 resource can be transmitted.

[0200] - When the base station sets and activates periodic radio resources (e.g., CG) for the UE, the base station can allocate a plurality of radio resources to the UE within one period. The plurality of radio resources may be such that the same time / frequency resource allocation within a slot is repeated at regular intervals (e.g., every M (M is a natural number) slots) (e.g., radio resources of 3 symbols per slot are repeatedly allocated at the same position), or radio resources having the same length may be continuously and repeatedly allocated to symbols consecutive to the first radio resource (e.g., radio resources of 3 symbols are continuously and repeatedly allocated). The number N (N is a natural number) of radio resources may be determined by L1 signaling and / or upper layer signaling. For example, in FIG. 8, both CG PUSCH 1 and CG PUSCH 2 illustrate the case where only one radio resource is allocated within one period, but a plurality of radio resources may be allocated within one period.

[0201] - The base station / UE can perform transmission using one or a part of the plurality of CG radio resources within the period according to a traffic pattern. Here, considering the time point when user data of the base station / UE is generated, the earliest radio resource capable of transmitting a transmission block (TB) containing the user data may be selected.

[0202] In the present disclosure, a base station can activate a plurality of CGs that are linked / associated with each other using one DCI or different DCIs. Here, the different CGs may be mapped to the same or different UL cells. Also, the different CGs may be mapped to the same or different UL BWPs (bandwidth parts). Also, the different CGs may be mapped to the same or different sets of RBs (resource blocks). For example, when two CGs are linked / associated, different periodic CG PUSCH resources for the two CGs may be allocated to one or more UL cells or one or more UL BWPs or one or more sets of RBs.

[0203] Example 1: When a plurality of CG settings set in a UE are linked / associated with each other, the CG PUSCH for each CG setting may be transmitted and received as follows.

[0204] Here, the plurality of CG settings may be mapped to one or more different logical channels from each other, or may be mapped to the same one or more logical channels, or may be mapped to some overlapping logical channels.

[0205] When CG1 (i.e., CG Configuration Index 1) (e.g., CG-ConfigIndex) is mapped to a logical channel for an I-frame, and CG2 (i.e., CG Configuration Index 2) is mapped to both a logical channel for an I-frame and a logical channel for a P-frame, and CG1 and CG2 are set as linked / associated CGs, the UE can transmit different CG PUSCHs to each other as follows.

[0206] In such a CG configuration, multiple TBs for an I-frame may be transmitted by CG PUSCHs for multiple CGs. For example, as shown in FIG. 8, the logical channel data for an I-frame may be divided into two TBs and transmitted by PUSCH 1 for CG1 and PUSCH 2 for CG2.

[0207] Method 1-1: The UE can determine that the CG2 resources are valid only when there is a CG1 transmission. In other words, when two concatenated / associated CG configurations are set for the UE, the CG PUSCH resources for the other CG configuration may be valid when CG PUSCH transmission for either one of the CG configurations is performed (or when an ACK for this is received). Here, a non-valid CG PUSCH resource can mean that no CG PUSCH resource is allocated.

[0208] That is, assuming that CG2 has its PUSCH resources allocated by CG1, the UE can determine the CG PUSCH transmission for CG2 when it is determined that there is a CG1 PUSCH transmission (i.e., when it is performed) or when HARQ-ACK information (e.g., ACK) for the CG PUSCH transmission for CG1 is received.

[0209] Method 1-2: The UE can activate CG2 only when there is a CG1 transmission. In other words, when two concatenated / associated CG configurations are set for the UE, the other CG configuration may be activated when CG PUSCH transmission for either one of the CG configurations is performed (or when an ACK for this is received).

[0210] For example, when the base station instructs the activation of CG1 and CG2 with one DCI, the UE can first activate CG1. Then, when there is a TB to be transmitted by CG1 PUSCH (or when HARQ-ACK information (e.g., ACK) for CG1 PUSCH is received), CG2 can be activated and CG2 PUSCH can be transmitted.

[0211] Here, when there is no TB to be transmitted by CG1 PUSCH in the resource allocated for CG1 PUSCH transmission, or when it is determined that there is no data to be transmitted by CG1 PUSCH for a certain period of time, or when CG1 PUSCH transmission fails or a NACK is received, the UE can determine that CG2 is deactivated (or can deactivate the activated CG2).

[0212] If necessary, even when the base station has already instructed the activation of CG1 and CG2 with the first DCI, the base station can instruct the activation / release of CG2 with another second DCI. When the two DCIs (the first DCI and the second DCI) activate the same CG2, the UE can reactivate CG2 with the last received DCI (i.e., the second DCI) even if CG2 is already activated.

[0213] Method 1-3: The UE can determine whether to transmit CG2 PUSCH based on the MAC PDU header or MAC CE content / content transmitted by CG1 PUSCH. In other words, when two concatenated / associated CG settings are set for the UE, whether to transmit CG PUSCH for the other CG setting can be determined by the content within the CG PUSCH transmission for either one of the CG settings. Here, determining whether to transmit CG PUSCH can also mean whether the CG PUSCH resource for the CG setting is allocated (i.e., whether it is valid), or can also mean whether the CG setting is activated.

[0214] For example, the LCID field of the MAC PDU transmitted by CG1 PUSCH, or the MAC CE, can indicate (notify) the start of the GOP pattern, or indicate the logical channel corresponding to the I-frame, or indicate the concatenated CG2 transmission or activation. In this case, the UE can activate the deactivated CG2 and transmit the TB of the next frame (e.g., P-frame) on the activated CG2 PUSCH.

[0215] Embodiment 2: When multiple CG settings set for the UE are concatenated / associated with each other, the CG PUSCH for each CG setting may be transmitted and received as follows.

[0216] Here, the multiple CG settings may be mapped to one or more different logical channels from each other, or may be mapped to the same one or more logical channels, or may be mapped to some overlapping logical channels.

[0217] When CG1 (i.e., CG Configuration Index 1) is mapped to the logical channel for the I-frame and CG2 (i.e., CG Configuration Index 2) is mapped to the logical channel for the P-frame, and CG1 and CG2 are set as concatenated / associated CGs, the UE can transmit different CGs from each other as follows.

[0218] In such a CG setting, multiple TBs for the I-frame may be transmitted on multiple CG PUSCHs for CG1. For example, as shown in FIG. 8, the logical channel data for the I-frame may be divided into two TBs and transmitted on different (consecutive) PUSCH 1s for CG1.

[0219] Method 2-1: CG PUSCH resources may not be allocated for a specific (one or more) CG period of CG2. In other words, when two concatenated / associated CG settings are set for the UE, the CG PUSCH resources within a specific one or more periods of a specific CG setting may not be allocated (may be invalid).

[0220] For example, the UE can determine that the CG PUSCH resources assigned to a specific (one or more) CG period of CG2 that overlaps with the CG1 PUSCH transmission are invalid. And / or, the base station does not have to assign CG PUSCH resources to a specific (one or more) CG period of CG2 that overlaps with the CG1 PUSCH transmission.

[0221] A mask (i.e., a section where CG PUSCH is not transmitted) may be set in CG period units so as to invalidate or not assign the CG PUSCH resources of the specific Mth (or one or more) overlapping CG periods in such a manner. Thereby, the UE and the base station do not have to invalidate or assign the CG PUSCH resources of the specific Mth (or one or more) CG periods where the mask is set.

[0222] Method 2-2: CG2 transmission may be skipped in (one or more) CG2 periods that overlap with CG1. In other words, when two concatenated / associated CG settings are set for the UE, CG PUSCH transmission may be skipped within one or more specific periods of a specific CG setting that overlaps with other CG settings. That is, although CG PUSCH resources are assigned within the one or more periods, CG PUSCH transmission may be skipped.

[0223] The UE can skip the PUSCH transmission assigned to a specific (one or more) CG period of CG2 that overlaps with the CG1 PUSCH transmission.

[0224] In such a manner, a mask may be set in CG period units to skip the specific Mth (or one or more) overlapping CG periods. Thereby, the UE and the base station can skip the CG PUSCH transmission of the specific Mth (or one or more) CG periods where the mask is set.

[0225] Here, ACK may be transmitted as the HARQ-ACK information for the skipped CG PUSCH. Alternatively, the response of the HARQ-ACK information for the skipped CG PUSCH may also be skipped.

[0226] Method 2-3: When CG1 PUSCH transmission is executed in a specific CG1 period, or when CG1 PUSCH is transmitted in a specific CG1 period, the CG2 PUSCH resources in the CG2 period starting after the CG1 PUSCH transmission can be determined to be valid. Thereby, the UE can perform CG2 PUSCH transmission with the valid CG2 PUSCH resources. In other words, when two concatenated / associated CG configurations are set for the UE, when a CG PUSCH for either one of the CG configurations is transmitted, a CG PUSCH may be transmitted within one or more periods for the other CG configuration starting after the CG PUSCH transmission.

[0227] Embodiment 3: When a plurality of CG configurations set for the UE are concatenated / associated with each other, the CG PUSCH transmission for one of the CG configurations may indicate the CG PUSCH transmission for the other CG configuration.

[0228] Here, the plurality of CG configurations may be mapped to one or more logical channels that are different from each other, or may be mapped to the same one or more logical channels, or may be mapped to some overlapping logical channels.

[0229] When CG1 (i.e., CG Configuration Index 1) is mapped to the logical channel for the I-frame and CG2 (i.e., CG Configuration Index 2) is mapped to the logical channel for the P-frame, and CG1 and CG2 are set as concatenated / associated CGs, the UE can activate all the concatenated / associated CGs by DCI and indicate the transmission of CG1 PUSCH or CG2 PUSCH in period N + k (K is a natural number) by the CG1 PUSCH transmission in period N (N is a natural number).

[0230] In other words, when two concatenated / associated CG configurations are set for a UE, CG PUSCH transmissions within a specific period of a specific CG configuration may indicate, by means of CG PUSCH transmissions in one or more periods for the said CG configuration and / or the remaining CG configurations at a later time.

[0231] For example, the UE may notify the start of a GOP pattern in the sub-header of a CG1 PUSCH with a period of N or in a MAC CE, or indicate a logical channel corresponding to an I-frame, or indicate concatenated CG2 transmissions or activation. After the said CG1 PUSCH transmission, the UE may perform CG2 PUSCH transmissions in the k-th period (k = 1, 2, 3,..., M). After performing M CG2 PUSCH transmissions according to the GOP pattern, the UE does not have to perform CG2 PUSCH transmissions until the next CG1 PUSCH transmission. The base station may expect CG2 PUSCH transmissions in the k-th period (k = 1, 2, 3,..., M) after the said CG1 PUSCH transmission according to the said indication.

[0232] Here, the UE may perform a plurality of CG2 PUSCH transmissions following the k-th period. For example, when expecting three P-frame uplink transmissions immediately after an I-frame according to information indicated by the upper layer of the UE or information notified by the base station, the UE may perform CG2 PUSCH transmissions in the k-th, k+1-th, and k+2-th periods (k = 1, 2, 3,..., M) immediately after the said CG1 PUSCH transmission.

[0233] In addition, the UE may receive information regarding the said GOP pattern from the base station in an RRC message or a MAC CE or DCI for setting or activating CG1 and CG2.

[0234] Embodiment 4: Information regarding the start time of a CG PUSCH within the next CG period (i.e., the next CG PUSCH transmission period) (i.e., information related to the resource at which the CG PUSCH starts) may be adjusted / indicated by control information (e.g., DCI or MAC CE) from the base station.

[0235] - The base station and the UE can periodically allocate CG PUSCH time resources. Here, the base station can adjust / indicate the first resource of the CG PUSCH (i.e., in the PUSCH transmission generated by the resource allocation in the active CG PDCCH) in slot units using control information (e.g., DCI or MAC CE). Alternatively, the CG deactivated by the control information (e.g., DCI or MAC CE) can be activated, or the activated CG can be reactivated.

[0236] For example, the UE and the base station can periodically allocate CG PUSCH time resources according to Equation 7 below. Here, the base station can use control information (e.g., DCI or MAC CE) to adjust / indicate the slot start time (slot start time ) of Equation 7 in slot units.

[0237]

Number

[0238] In Equation 7, numberOfSlotsPerFrame represents the number of consecutive slots per frame, and numberOfSymbolsPerSlot represents the number of consecutive symbols per slot. Also, in Equation 7, N is an integer value corresponding to the Nth PUSCH transmission (i.e., TO). periodicity is the transmission period of the CG PUSCH and may be set by configuredGrantConfig (see Table 6). SFN start time , slot start time respectively represent the SFN and slot of the first transmission (i.e., the first resource (TO)) of the PUSCH for which the CG is (re)initialized (i.e., in the PUSCH transmission generated by the resource allocation in the active PDCCH).

[0239] - For example, when adjusting / indicating the time resource of the CG PUSCH (i.e., the resource at which the CG PUSCH starts) using a MAC CE, the MAC CE includes the CG configuration index (e.g., CG-ConfigIndex) value of the CG to be adjusted / indicated, and as an example of information related to the resource at which the CG PUSCH starts, the newly applied slot start time (slot start time ) can indicate the absolute slot value or the slot unit offset value by which the existing slot is changed.

[0240] The UE can apply the information related to the resource at which the CG PUSCH starts (e.g., the adjusted slot value) from the time when the next CG cycle starts after receiving the MAC CE or after transmitting an ACK for the MAC CE. That is, when the adjusted slot start time is indicated, the adjusted slot start time can be applied from the next CG cycle after that time.

[0241] - As another example, when adjusting / indicating the time resource of the CG PUSCH (i.e., the resource at which the CG PUSCH starts) using DCI, the DCI may be scrambled with a CS-RNTI or a new RNTI (i.e., a new RNTI defined for the purpose of adjusting / indicating the CG PUSCH time resource) in the CRC. Here, the HARQ process ID of the DCI indicates the CG configuration index (e.g., CG-ConfigIndex) value of the corresponding CG, and as an example of information related to the resource at which the CG PUSCH starts, the newly applied slot start time (slot start time ) can indicate the absolute slot value or the slot unit offset value by which the existing slot is changed.

[0242] When the UE finishes receiving the DCI, or when it transmits HARQ-ACK information (e.g., ACK) for the DCI, or when it finishes transmitting the PUSCH scheduled by the DCI, or when it transmits HARQ-ACK information (e.g., ACK) for the PUSCH scheduled by the DCI, the UE can apply information related to the resource where the CG PUSCH starts (e.g., the adjusted slot value) from the time when the next CG period starts. Here, the HARQ-ACK information (e.g., ACK) for the DCI or the HARQ-ACK information (e.g., ACK) for the PUSCH scheduled by the DCI may be transmitted on the PUCCH resource indicated by the DCI, or (if there is no indicated PUCCH resource) on the PUCCH resource of A / N set for the CG, which is the closest PUCCH resource after a certain time.

[0243] - When the resource where the CG PUSCH of the periodic CG PUSCH starts (e.g., the start slot of the CG PUSCH) is adjusted / instructed by the method described above, the CG period is not changed in the next CG period, and only the start slot of the periodic CG PUSCH resource may be changed. Alternatively, the CG period may also be changed in slot units according to the change of the CG PUSCH resource. For example, when information related to the resource where the CG PUSCH starts, such as a slot start time value, is indicated by control information (e.g., DCI or MAC CE), the indicated slot start time value in Formula 7 is applied, and the resource where the transmission of the CG PUSCH starts may be determined.

[0244] - Also, in Formula 7, together with the slot start time (slot start time ), the symbol start time (symbol start time) may be added. Then, using control information (e.g., DCI or MAC CE), as an example of information related to the resource where the CG PUSCH starts, the absolute symbol value of the symbol (symbol start time ) or the symbol unit offset value changed from the existing symbol can be indicated. That is, in the above-described method, as an example of information related to the resource where the CG PUSCH starts, control information (e.g., DCI or MAC CE) may indicate symbol start time instead of slot start time , or may indicate symbol start time together with slot start time . The UE that receives this can apply the information related to the resource where the CG PUSCH starts (e.g., the adjusted slot start time and / or symbol start time ) value from the next CG period or from the next CG PUSCH resource or from the CG PUSCH resource of the next CG period.

[0245] For example, when using control information (e.g., DCI or MAC CE), as information related to the resource where the CG PUSCH starts, if the values of slot start time and / or symbol start time are indicated, the indicated slot start time and / or symbol start time values may be applied according to the following formula 8, and the resource where the transmission of the CG PUSCH starts may be determined.

[0246]

Number

[0247] In Equation 8, numberOfSlotsPerFrame represents the number of consecutive slots per frame, and numberOfSymbolsPerSlot represents the number of consecutive symbols per slot. Also in Equation 8, N is an integer value corresponding to the Nth PUSCH transmission (i.e., TO). periodicity is the transmission period of the CG PUSCH and may be set by configuredGrantConfig (see Table 6). SFN start time , slot start time , symbol start time respectively represent the SFN, slot, and symbol of the first transmission (i.e., the first resource (TO)) of the PUSCH for which the CG is (re)initialized (i.e., in the PUSCH transmission generated by the resource allocation in the active PDCCH).

[0248] - Also, the base station can adjust the resource (e.g., slot start time (slot start time ) and / or symbol start time (symbol start time ) at which the CG PUSCH for a specific CG (e.g., the CG associated / linked with the specific uplink transmission) starts for a specific uplink transmission (e.g., PUSCH, PUCCH, uplink traffic, uplink control information (UCI)) transmitted by the UE, or activate a linked deactivated CG, or reactivate a linked activated CG.

[0249] For example, a UE that supports virtual reality (VR) can report pose information to the base station based on the motion of the user wearing the VR UE. For example, the VR UE can transmit the pose information to the base station at a period of 4 ms.

[0250] Therefore, for example, a base station can set / assign another logical channel for transmitting pose information and configure it to be mapped / associated with a configured grant (CG) specified for the pose. Then, the specific CG may be set / defined to transmit only the data of the logical channel for the pose in the uplink. Here, the PUSCH resource for the specific CG can transmit the UCI piggybacked together (i.e., transmit the TB and UCI together). For example, such UCI can indicate whether there is a change in pose information. For example, when there is a pose change of a user above a threshold compared to 4 ms before (i.e., when sensed by the UE), 1 can be indicated by the UCI, and 0 can be indicated otherwise. Or, when there is a pose change compared to 4 ms before (i.e., when sensed by the UE), 1 can be indicated by the UCI, and 0 can be indicated when there is no pose change. Or, when multiple stage-by-stage thresholds are defined / set, the largest pose change can be indicated as 11, a smaller pose change as 10, an even smaller pose change as 01, and no pose change as 00. The bit values indicated by the UCI described above are only examples, and the present disclosure is not limited thereto.

[0251] On the other hand, the TB of the PUSCH for the pose may include the pose information of the upper layer.

[0252] Also, when there is no pose change or when the pose change is small and below the threshold, the UE may skip all transmissions of the pose-related CG PUSCH and the UCI piggybacked thereon. Here, the data unit (e.g., the TB including the pose information) for the pose information with no pose change may also be discarded. For example, when there is no pose change or when the pose change is small and below the threshold, the PDCP (packet data convergence protocol) entity that provides the radio bearer for the pose information can discard the data unit for the pose information. As yet another example, when there is no pose change or when the pose change is small and below the threshold, the UE may be configured to expire the PDCP discard timer for the data unit of the pose information in the PDCP entity and discard the data unit.

[0253] Alternatively, when there is no pose change or when the pose change is small and below the threshold, the UE can discard the TB that contains only such pose information.

[0254] Alternatively, when there is no pose change or when the pose change is small and below the threshold, the upper layer of the UE can discard such pose information or transmit it on a logical channel with another radio bearer. Here, the PDCP entity for the other radio bearer may be configured with a PDCP discard timer shorter than that of the PDCP entity.

[0255] As yet another example, the base station can set / assign another logical channel for transmitting pose information, and set it to be mapped / associated with a specific PUCCH resource and a specific scheduling request (SR) setting. Then, when pose information for the logical channel occurs, the pose information may trigger a buffer state request (BSR), and the BSR may be set to trigger an SR. Here, for example, the BSR MAC CE can indicate that there is pose information transmitted by the UE according to the value of a logical channel group field or other specific fields. Alternatively, when pose information for the logical channel occurs, it may be set to directly trigger an SR without a BSR. When the SR for pose is triggered, the UE can transmit UCI on the corresponding PUCCH resource.

[0256] Here, it may be set not to trigger a BSR or an SR when there is no pose change or when the pose change is small and below a threshold. Alternatively, when there is no pose change or when the pose change is small and below a threshold, the pose information may be discarded, and it may be set not to trigger a BSR or an SR.

[0257] By transmitting UCI indicating or including the pose information, or PUCCH transmission, or CG PUSCH transmission, the base station and the UE can, according to the pose information, determine the resource (e.g., slot start time (slot start time ) and / or symbol start time (symbol start time ) at which the CG PUSCH of a specific CG (e.g., a concatenated / associated CG) starts may be adjusted. For example, when the pose information indicates a change in jitter or when the UCI or PUCCH for the pose information requests a CG time point change, the base station and the UE can determine the resource at which the CG PUSCH of a specific CG PUSCH for XR traffic concatenated / associated with the pose information starts (e.g., slot start time (slotstart time ) and / or symbol start time (symbol start time ) can be adjusted. Alternatively, the base station can transmit DCI indicating a CG configuration index (e.g., CG-ConfigIndex) for the XR traffic CG to activate a concatenated deactivated CG or reactivate a concatenated activated CG.

[0258] For this purpose, the base station can concatenate the pause information with a specific CG configuration index (e.g., CG-ConfigIndex) or concatenate the pause information with a specific SR configuration. The UE and the base station can concatenate such a specific CG (e.g., the CG for transmitting the pause information) or a specific SR configuration with a specific CG (e.g., the CG for transmitting XR traffic). Thus, CG-UCI or CG-PUSCH transmission for the specific CG concatenated with the pause, or specific SR PUCCH transmission concatenated with the pause, is at the resource where the CG PUSCH starts (e.g., slot start time (slot start time ) and / or symbol start time (symbol start time ) is set to indicate, in the next CG period of the specific CG PUSCH for the concatenated XR traffic, the resource where the CG PUSCH starts (e.g., slot start time (slot start time ) and / or symbol start time (symbol start time )) may be adjusted.

[0259] Alternatively, the UE can use RRC signaling (e.g., an RRC assistant information message) to indicate the resource where the CG PUSCH adjusted for the specific CG PUSCH for XR traffic starts (e.g., slot start time (slot start time ) and / or symbol start time (symbol start time)) The value can be reported to the base station.

[0260] FIG. 9 illustrates the signaling procedure between the network and the UE for the configured grant PUSCH transmission / reception method according to an embodiment of the present disclosure.

[0261] FIG. 9 illustrates the signaling between the network (e.g., TRP1, TRP2) and the UE for the method proposed in the present invention (e.g., embodiments 1 to 4, combinations of one or more of the proposed methods in embodiments 1 to 4). Here, the UE / network is merely an example and may be alternatively applied to various devices. FIG. 9 is only for convenience of explanation and does not limit the scope of the present disclosure. Also, some of the steps illustrated in FIG. 9 may be omitted depending on the situation and / or settings, etc.

[0262] The signaling method described in FIG. 9 may also be extended and applied to the signaling between a plurality of TRPs and a plurality of UEs. In the following description, the network may be one base station including a plurality of TRPs, or may be one cell including a plurality of TRPs. As an example, an ideal / non-ideal backhaul may be set between TRP 1 and TRP 2 constituting the network. Also, the following description is described based on a plurality of TRPs, and this may be equally extended and applied to transmission using a plurality of panels. In the present disclosure, the operation of the UE receiving a signal from TRP 1 / TRP 2 may also be interpreted / explained as the operation of the UE receiving a signal from the network (via / using TRP 1 / 2) (or may be the operation), and the operation of the terminal transmitting a signal to TRP 1 / TRP 2 may be interpreted / explained as the operation of the UE transmitting a signal to the network (via / using TRP 1 / TRP 2) (or may be the operation), and the reverse interpretation / explanation is also possible.

[0263] The base station may be a general term for objects that transmit and receive data with the UE. For example, the base station may be a concept including one or more TPs (Transmission Points), one or more TRPs (Transmission and Reception Points), etc. Also, the TP and / or TRP may include a panel of the base station, a transmission and reception unit, etc. Further, "TRP" may be applied as an alternative to expressions such as a panel, an antenna array, a cell (e.g., macro cell / small cell / pico cell, etc.), a TP (transmission point), a base station (gNB), etc. As described above, the TRP may be classified by information (e.g., index, ID) for a CORESET group (or, CORESET pool). As an example, when one UE is set to transmit and receive with a plurality of TRPs (or, cells), this may mean that a plurality of CORESET groups (or, CORESET pools) are set for one UE. Such a setting for the CORESET group (or, CORESET pool) may be performed by upper layer signaling (e.g., RRC signaling, etc.).

[0264] The UE can receive configuration information from the network (S901).

[0265] The configuration information may include information related to the configuration of the network (e.g., TRP configuration) / information related to M-TRP based transmission and reception (e.g., resource allocation, etc.). At this time, the configuration information may be transmitted by upper layer signaling (e.g., RRC signaling, MAC-CE, etc.).

[0266] The setting information may include setting information related to the CG setting described by the above-described proposed method (for example, the proposed methods in Embodiments 1 to 4, combinations of one or more proposed methods in Embodiments 1 to 4). For example, one or more CG settings may be set for the UE, and the setting information may include individual setting information (for example, configuredGrantConfig IE) for each of the one or more CG settings. Here, the individual setting information for each of the one or more CG settings may include the information / parameters exemplified in Table 6 above.

[0267] Also, for example, according to the above-described embodiments, the individual setting information for each CG setting may include information related to the logical channel associated with the CG setting.

[0268] The UE can receive downlink control information from the network (S902).

[0269] As described above, the CG Type 1 PUSCH transmission may be set to operate semi-statically when receiving setting information (for example, configuredGrantConfig including rrc-ConfiguredUplinkGrant) for the CG setting without detecting the UL grant in the DCI. In this case, the step of S902 may be omitted. Also, in this case, the TCI state for one or more CG settings set for the UE may be set by the setting information (for example, configuredGrantConfig IE) related to the CG setting, or may be set / instructed by the above-described MAC CE.

[0270] In addition, the CG Type 2 PUSCH transmission may be semi-statically scheduled by a UL grant in a valid activation DCI after receiving configuration information for the CG configuration (e.g., configuredGrantConfig not including rrc-ConfiguredUplinkGrant). In this case, the DCI in step S902 may correspond to the valid activation DCI. Also, in this case, the TCI state for one or more CG configurations set for the UE may be set by configuration information related to the CG configuration (e.g., configuredGrantConfig IE), set / instructed by the above-described MAC CE, or instructed by the valid activation DCI.

[0271] The UE transmits a configured grant (CG) PUSCH to the network (S903).

[0272] Here, the UE can transmit the CG PUSCH to the network based on the operations described by the above-described proposed methods (e.g., Examples 1 to 4, combinations of one or more proposed methods in Examples 1 to 4).

[0273] For example, according to the first embodiment, when a plurality of CG configurations set for the UE are linked / associated with each other, the UE can determine that the resources for other CG configurations are valid or that other CG configurations are activated only when there is a transmission for a specific CG configuration. Also, the UE can determine whether to transmit the CG PUSCH for other CGs via the CG PUSCH for a specific CG.

[0274] Also, for example, according to the above-described Example 2, when a plurality of CG settings set in the UE are connected / associated with each other, for the CG PUSCH transmission period for the CG2 setting that overlaps with the CG1 setting, the CG PUSCH resource for CG2 may not be allocated, and the UE may skip the CG PUSCH transmission. Also, the CG PUSCH for the CG2 setting may be transmitted in the next CG PUSCH transmission period only when there is a CG1 PUSCH transmission.

[0275] Also, for example, according to the above-described Example 3, when a plurality of CG settings set in the UE are connected / associated with each other, the CG PUSCH transmission for one CG setting may indicate the CG PUSCH transmission for the other CG setting.

[0276] Also, for example, according to the above-described Example 4, information related to the resource at which the next CG PUSCH transmission for one or more CG settings occurs (or the CG PUSCH transmission is resumed (or started)) is transmitted and received by downlink control information (e.g., DCI or MAC CE) or uplink control information (UCI), so that the CG PUSCH may not be transmitted before the resource determined by the information. Then, the CG PUSCH for the one or more CG settings may be transmitted at (or from) the resource determined by the information related to the resource at which the CG PUSCH is resumed.

[0277] In this case, although not shown in FIG. 9, the UE can send UCI to the network. Here, the UCI may include information related to a resource where the next CG PUSCH transmission for one or more CG settings occurs (or a resource where the CG PUSCH transmission resumes (or starts)). Also, the information related to the resource where the next CG PUSCH transmission occurs may be indicated in units of slots or symbols. For example, the information related to the resource where the next CG PUSCH transmission occurs may indicate the slot or symbol of the resource where the next CG PUSCH transmission occurs or may indicate an offset value from the slot or symbol of the resource where the next CG PUSCH transmission occurs.

[0278] Also, the UCI may be sent on a CG PUSCH for a specific CG setting associated with the transmission of the UCI. Here, the CG PUSCH for the specific CG setting includes only data for a specific logical channel mapped to the specific CG setting, and the UCI may be piggybacked on the CG PUSCH for the specific CG setting. Or, the UCI may be sent on a PUCCH based on an SR associated with the UCI.

[0279] Thus, when the UCI includes information related to a resource where the next CG PUSCH transmission for the one or more CG settings occurs, the CG PUSCH may not be transmitted before the resource determined by the information related to the resource where the next CG PUSCH transmission occurs. And at (or from) the resource determined by the information related to the resource where the next CG PUSCH transmission occurs, the CG PUSCH for the one or more CG settings may be transmitted. Here, the one or more CG settings are set to be associated with the UCI, and based on the UCI, a resource where the next CG PUSCH transmission for the associated one or more CG settings occurs may be determined.

[0280] FIG. 10 is a diagram illustrating the operation of a UE with respect to a configured grant PUSCH transmission / reception method according to an embodiment of the present disclosure.

[0281] Referring to FIG. 10, FIG. 10 illustrates the operation of a UE based on the previous proposed methods (e.g., Embodiments 1 to 4, combinations of one or more proposed methods in Embodiments 1 to 4). The illustration in FIG. 10 is for convenience of explanation and does not limit the scope of the present disclosure. Some steps illustrated in FIG. 10 may be omitted depending on the situation and / or settings. Also, in FIG. 10, the UE is merely an illustration and may be implemented by the apparatus illustrated in FIG. 12.

[0282] Also, the operations in FIG. 10 may be processed by one or more processors 102, 202 in FIG. 12, and the operations in FIG. 10 may be stored in a memory (e.g., one or more memories 104, 204 in FIG. 12) in the form of instruction words / programs (e.g., instructions, executable code) for driving at least one processor (e.g., 102, 202) in FIG. 12.

[0283] The UE receives individual configuration information related to one or more configured grants (CGs) from the base station (S1001).

[0284] The configuration information related to the CG configuration may include information related to the CG configuration described by the above-mentioned proposed methods (e.g., Embodiments 1 to 4, combinations of one or more proposed methods in Embodiments 1 to 4). For example, one or more CG configurations may be set for the UE, and the individual configuration information (e.g., configuredGrantConfig IE) for each of the one or more CG configurations may include the information / parameters illustrated in Table 6 above.

[0285] Also, for example, according to the above-described embodiments, the individual setting information for each CG setting may include information regarding the logical channel associated with the CG setting.

[0286] The UE can receive downlink control information from the base station (S1002).

[0287] As described above, the CG Type 1 PUSCH transmission may be set to operate semi-statically when receiving setting information (e.g., configuredGrantConfig including rrc-ConfiguredUplinkGrant) for the CG setting without detecting the UL grant in the DCI. In this case, the step of S1002 may be omitted. Also, in this case, the TCI state for one or more CG settings set in the UE may be set by the setting information (e.g., configuredGrantConfig IE) related to the CG setting, or set / instructed by the above-described MAC CE.

[0288] Also, the CG Type 2 PUSCH transmission may be semi-statically scheduled by the UL grant in the valid activation DCI after receiving the setting information (e.g., configuredGrantConfig not including rrc-ConfiguredUplinkGrant) for the CG setting. In this case, the DCI in the S1002 step may correspond to the valid activation DCI. Also, in this case, the TCI state for one or more CG settings set in the UE may be set by the setting information (e.g., configuredGrantConfig IE) related to the CG setting, or set / instructed by the above-described MAC CE, or instructed by the valid activation DCI.

For example, the information related to the resource where the next CG PUSCH transmission occurs may indicate the slot or symbol of the resource where the next CG PUSCH transmission occurs, or may indicate an offset value from the slot or symbol of the resource where the next CG PUSCH transmission occurs.

Here, the CG PUSCH for the specific CG setting includes only data for a specific logical channel mapped to the specific CG setting, and the UCI may be piggybacked on the CG PUSCH for the specific CG setting. Or, the UCI may be transmitted on a PUCCH based on an SR associated with the UCI.

[0292] The UE transmits a configured grant (CG) PUSCH to the base station (S1004).

[0293] As described above, when the UCI includes information related to a resource where the next CG PUSCH transmission for the one or more CG settings occurs, before the resource determined by the information related to the resource where the next CG PUSCH transmission occurs, the UE does not have to transmit the CG PUSCH to the base station. And at (or from) the resource determined by the information related to the resource where the next CG PUSCH transmission occurs, the UE can transmit the CG PUSCH for the one or more CG settings to the base station. Here, the one or more CG settings are set to be associated with the UCI, and based on the UCI, the resource where the next CG PUSCH transmission for the associated one or more CG settings occurs may be determined.
