Description

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

[0001] The present disclosure relates to a wireless communication system, and more specifically, to a method and apparatus for transmitting and receiving uplink / downlink wireless signals in a wireless communication system.

[0002] Mobile communication systems were developed to provide voice services while ensuring user mobility. However, mobile communication systems have expanded their scope to include data services as well as voice. Currently, due to the explosive increase in traffic leading to resource shortages and users demanding higher-speed services, more advanced mobile communication systems are required.

[0003] The requirements for next-generation mobile communication systems largely include the ability to accommodate explosive data traffic, a dramatic increase in transmission rates per user, a significantly increased number of connected devices, very low end-to-end latency, and high energy efficiency. To achieve this, various technologies are being researched, such as dual connectivity, massive multiple input multiple output (MMIMO), in-band full duplex, non-orthogonal multiple access (NOMA), super wideband support, and device networking.

[0004] The technical problem of the present disclosure is to provide a method and apparatus for transmitting and receiving uplink / downlink wireless signals according to periodic resource allocation, taking into account the measurement gap in a wireless communication system.

[0005] The technical problems to be solved in this disclosure are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this disclosure belongs from the description below.

[0006] A method according to one aspect of the present disclosure may include: receiving first setting information related to setting periodic resource allocations for downlink reception or uplink transmission from a base station by a user device (UE: user equipment), wherein the location of a plurality of resource allocations for downlink reception or uplink transmission is determined in a time domain based on the first setting information; receiving second setting information related to a measurement gap from the base station by the UE; and performing downlink reception or uplink transmission by changing the location of one or more resource allocations based on the fact that the location of one or more of the plurality of resource allocations overlaps with a interval of the measurement gap by the UE.

[0007] In a further aspect of the present disclosure, a method may comprise: a step of transmitting, by a base station, first setting information related to setting periodic resource allocations for downlink transmission or uplink reception to a user device (UE: user equipment), wherein the location of a plurality of resource allocations for downlink transmission or uplink reception is determined in a time domain based on the first setting information; a step of transmitting, by the base station, second setting information related to a measurement gap to a terminal; and a step of performing downlink transmission or uplink reception by changing the location of one or more resource allocations based on the fact that the location of one or more of the plurality of resource allocations overlaps with a interval of the measurement gap.

[0008] According to an embodiment of the present disclosure, transmission and reception of uplink / downlink wireless signals are possible even in periodic resource allocations overlapping in the measurement gap interval, thereby supporting efficient transmission and reception of delay-sensitive traffic.

[0009] The effects obtainable from the present disclosure are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art to which the present disclosure belongs from the description below.

[0067] General System

[0068] As more communication devices require larger communication capacities, the need for enhanced mobile broadband communication compared to existing radio access technology (RAT) is emerging. Furthermore, Massive Machine Type Communications (MTC), which connects multiple devices and objects to provide various services anytime and anywhere, is also one of the major issues to be considered in next-generation communication. In addition, communication system designs that take into account services and terminals sensitive to reliability and latency are being discussed. As such, the introduction of next-generation RATs considering eMBB (enhanced mobile broadband communication), Mmtc (massive MTC), and URLLC (Ultra-Reliable and Low Latency Communication) is being discussed, and for convenience, this technology is referred to as NR in this disclosure. NR is an expression representing an example of 5G RAT.

[0069] A new RAT system including NR uses an OFDM transmission method or a similar transmission method. The new RAT system may follow OFDM parameters different from those of LTE. Alternatively, the new RAT system may follow the existing LTE / LTE-A numerology but support a larger system bandwidth (e.g., 100 MHz). Or, a single cell may support multiple numerologies. That is, terminals operating with different numerologies can coexist within a single cell.

[0070] Numerology corresponds to a single subcarrier spacing in the frequency domain. Different numerologies can be defined by scaling the reference subcarrier spacing to an integer N.

[0071] FIG. 1 illustrates the structure of a wireless communication system to which the present disclosure can be applied.

[0072] Referring to FIG. 1, the NG-RAN consists of gNBs that provide NG-RA (NG-Radio Access) user plane (i.e., new access stratum (AS) sublayer / PDCP (Packet Data Convergence Protocol) / RLC (Radio Link Control) / MAC / PHY) and control plane (RRC) protocol endpoints for the UE. The gNBs are interconnected via Xn interfaces. The gNBs are also connected to the NGC (New Generation Core) via NG interfaces. More specifically, the gNBs are connected to the AMF (Access and Mobility Management Function) via N2 interfaces and to the UPF (User Plane Function) via N3 interfaces.

[0073] FIG. 2 illustrates a frame structure in a wireless communication system to which the present disclosure may be applied.

[0074] An NR system can support multiple numerologies. Here, the numerology can be defined by subcarrier spacing and cyclic prefix (CP) overhead. In this case, multiple subcarrier spacings can be derived by scaling the base (reference) subcarrier spacing by an integer N (or μ). Furthermore, the numerology used can be selected independently of the frequency band, even if it is assumed that very low subcarrier spacings are not used at very high carrier frequencies. Additionally, various frame structures based on multiple numerologies can be supported in an NR system.

[0075] Below, we examine the OFDM numerologies and frame structures that can be considered in NR systems. Many OFDM numerologies supported in NR systems can be defined as shown in Table 1 below.

[0076] μΔf=2 μ ·15 [kHz]CP015 Normal 130 Normal 260 Normal, Extended 3120 Normal 4240 Normal

[0077] NR supports multiple numerologies (or subcarrier spacing (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, lower latency, and wider carrier bandwidth; and when the SCS is 60 kHz or higher, it supports a bandwidth greater than 24.25 GHz to overcome phase noise.

[0078] The NR frequency band is defined by two types of frequency ranges (FR1, FR2). FR1 and FR2 can be configured as shown in Table 2 below. Additionally, FR2 may refer to millimeter wave (mmW).

[0079] Frequency Range Designation Corresponding Frequency Range Subcarrier Spacing FR1 4 10MHz - 7125MHz 15, 30, 60kHz FR2 24 250MHz - 52600MHz 60, 120, 240kHz

[0080] Regarding the frame structure in an NR system, the magnitude of various fields in the time domain is T c =1 / (Δf max ·N f It is expressed as a multiple of the time unit of ). Here, Δf max =480·10 3 Hz and N f = 4096. Downlink and uplink transmission is T f =1 / (Δf max N f / 100)·T c It is organized into radio frames having an interval of = 10ms. Here, each radio frame is T sf =(Δf max N f / 1000)·T c =1ms It consists of 10 subframes having the interval. In this case, there may be one set of frames for the uplink and one set of frames for the downlink. Additionally, the transmission at uplink frame number i from the terminal is T before the start of the corresponding downlink frame at the terminal.TA =(N TA +N TA,offset )T c Must start previously. For a subcarrier spacing configuration μ, the slots are n within the subframe. s μ ∈{0,..., N slot Numbered in increasing order of {subframe,μ-1}, and n within the radio frame s,f μ ∈{0,..., N slot frame,μ Numbers are assigned in increasing order of {-1}. One slot is N symb slot It consists of consecutive OFDM symbols of, and N symb slot is determined by CP. Slot n in the subframe s μ The start is OFDM symbol n in the same subframe. s μ N symb slot It is aligned with the start and time of. Not all terminals can transmit and receive simultaneously, which means that not all OFDM symbols in the downlink slot or uplink slot can be used.

[0081] Table 3 shows the number of OFDM symbols per slot in a standard CP (N symb slot ), number of slots per wireless frame (N slot frame,μ ), number of slots per subframe (N slot Table 4 shows the number of OFDM symbols per slot, the number of slots per wireless frame, and the number of slots per subframe in the extended CP.

[0083] μN symb slot N slot frame,μ N slot subframe,μ212404

[0084] FIG. 2 is an example of the case where μ=2 (SCS is 60 kHz), and referring to Table 3, 1 subframe can contain 4 slots. The 1 subframe={1,2,4} slot shown in FIG. 2 is an example, and the number of slot(s) that can be included in 1 subframe is defined as in Table 3 or Table 4. Additionally, a mini-slot can contain 2, 4, or 7 symbols, or more or fewer symbols.

[0085] Regarding physical resources in an NR system, antenna ports, resource grids, resource elements, resource blocks, and carrier parts may be considered. Below, we will examine in detail the aforementioned physical resources that can be considered in an NR system.

[0086] First, regarding antenna ports, an antenna port is defined such that the channel carrying a symbol on the antenna port can be inferred from the channel carrying another symbol on the same antenna port. If the large-scale property of the channel carrying a symbol on one antenna port can be inferred from the channel carrying a symbol on another antenna port, the two antenna ports can be said to be in a QC / QCL (quasi-co-located or quasi-co-location) relationship. Here, the large-scale property includes one or more of delay spread, Doppler spread, frequency shift, average received power, and received timing.

[0087] FIG. 3 illustrates a resource grid in a wireless communication system to which the present disclosure may be applied.

[0088] Referring to Fig. 3, the resource grid N in the frequency domain RB μ N sc RB It consists of subcarriers, and one subframe is 14.2 μ It is described by way of example that it consists of OFDM symbols, but is not limited thereto. In an NR system, the transmitted signal is N RB μ N sc RB One or more resource grids composed of subcarriers and 2 μ N symb (μ) It is described by the OFDM symbols of. Here, N RB μ≤ N RB max,μ It is. The above N RB max,μrepresents the maximum transmission bandwidth, which can vary not only between numerologies but also between uplink and downlink. In this case, a single resource grid can be established for each μ and antenna port p. Each element of the resource grid for μ and antenna port p is referred to as a resource element and is uniquely identified by an index pair (k,l'). Here, k=0,...,N RB μ N sc RB -1 is an index in the frequency domain, and l'=0,...,2 μ N symb (μ) -1 refers to the location of a symbol within a subframe. When referring to resource elements in a slot, an index pair (k,l) is used. Here, l=0,...,N symb μ It is -1. The resource factor (k,l') for μ and antenna port p is the complex value a k,l' (p,μ) It corresponds to. If there is no risk of confusion or if a specific antenna port or numerology is not specified, the indices p and μ may be dropped, and the resulting complex value is a k,l' (p) or a k,l' This can be. In addition, the resource block (RB) is N in the frequency domain. sc RB =12 is defined by consecutive subcarriers.

[0089] Point A serves as a common reference point for the resource block grid and is acquired as follows.

[0090] - OffsetToPointA for the Primary Cell (PCell) downlink represents the frequency offset between point A and the lowest subcarrier of the lowest resource block that overlaps with the SS / PBCH block used by the terminal for initial cell selection. It is expressed in resource block units assuming a 15 kHz subcarrier interval for FR1 and a 60 kHz subcarrier interval for FR2.

[0091] - absoluteFrequencyPointA represents the frequency-location of point A as expressed in ARFCN (absolute radio-frequency channel number).

[0092] Common resource blocks are numbered from 0 upward in the frequency domain for a subcarrier spacing setting μ. The center of subcarrier 0 of common resource block 0 for a subcarrier spacing setting μ coincides with 'point A'. Common resource block number n in the frequency domain CRB μ The relationship between the resource element (k,l) and the subcarrier spacing setting μ is given as Equation 1 below.

[0093]

[0094] In Equation 1, k is defined relative to point A such that k=0 corresponds to a subcarrier centered at point A. Physical resource blocks range from 0 to N within the bandwidth part (BWP). BWP,i size,μ Numbers are assigned up to -1, and i is the BWP number. Physical resource block n in BWP i PRB and common resource block n CRB The relationship between them is given by the following mathematical formula 2.

[0095]

[0096] N BWP,i start,μ is a common resource block where BWP starts relative to common resource block 0.

[0097] FIG. 4 illustrates a physical resource block in a wireless communication system to which the present disclosure may be applied. FIG. 5 illustrates a slot structure in a wireless communication system to which the present disclosure may be applied.

[0098] Referring to FIGS. 4 and 5, a slot contains multiple symbols in the time domain. For example, in the case of a standard CP, one slot contains 7 symbols, but in the case of an extended CP, one slot contains 6 symbols.

[0099] A carrier includes multiple subcarriers in the frequency domain. A Resource Block (RB) is defined as multiple (e.g., 12) consecutive subcarriers in the frequency domain. A Bandwidth Part (BWP) is defined as multiple consecutive (physical) resource blocks in the frequency domain and can correspond to a single numerology (e.g., SCS, CP length, etc.). A carrier may include up to N (e.g., 5) BWPs. Data communication is performed through the active BWPs, and only one BWP can be active for a single terminal. In the resource grid, each element is referred to as a Resource Element (RE) and can be mapped to a single complex symbol.

[0100] NR systems can support up to 400 MHz per Component Carrier (CC). If a terminal operating in such a wideband CC always keeps its radio frequency (RF) chip turned on for the entire CC, the terminal's battery consumption may increase. Alternatively, considering various use cases operating within a single wideband CC (e.g., eMBB, URLLC, Mmtc, V2X, etc.), different numerologies (e.g., subcarrier spacing) may be supported for each frequency band within that CC. Or, the capability regarding maximum bandwidth may vary by terminal. Taking this into account, the base station may instruct the terminal to operate only on a portion of the bandwidth rather than the entire bandwidth of the wideband CC, and for convenience, this portion of bandwidth is defined as the bandwidth part (BWP). A BWP can consist of consecutive RBs on the frequency axis and can correspond to a single numerology (e.g., subcarrier spacing, CP length, slot / mini-slot interval).

[0101] Meanwhile, the base station may configure multiple BWPs within a single CC configured for a terminal. For example, a BWP occupying a relatively small frequency range may be configured in the PDCCH monitoring slot, and the PDSCH indicated by the PDCCH may be scheduled on a larger BWP. Alternatively, if UEs are concentrated on a specific BWP, some terminals may be configured to a different BWP for load balancing. Or, considering frequency domain inter-cell interference cancellation between neighboring cells, a portion of the spectrum in the middle of the total bandwidth may be excluded, and both BWPs may be configured within the same slot. That is, the base station may configure at least one DL / UL BWP for a terminal associated with a broadband CC. The base station may activate at least one DL / UL BWP among the DL / UL BWP(s) configured at a specific time (by L1 signaling, MAC CE (Control Element), or RRC signaling, etc.). Additionally, the base station may instruct a switch to another configured DL / UL BWP (by L1 signaling, MAC CE, RRC signaling, etc.). Alternatively, a switch to a defined DL / UL BWP may occur based on a timer when the timer value expires. In this case, the activated DL / UL BWP is defined as the active DL / UL BWP. However, since the terminal may not receive the configuration for the DL / UL BWP in situations such as when the terminal is performing the initial access process or before the RRC connection is set up, the DL / UL BWP assumed by the terminal in such situations is defined as the initial active DL / UL BWP.

[0102] FIG. 6 illustrates physical channels used in a wireless communication system to which the present disclosure may be applied, and a general method of transmitting and receiving signals using these channels.

[0103] In a wireless communication system, a terminal receives information from a base station via the downlink and transmits information to the base station via the uplink. The information transmitted and received by the base station and the terminal includes data and various control information, and various physical channels exist depending on the type and purpose of the information being transmitted and received.

[0104] When the terminal is powered on or enters a new cell, it performs an initial cell search operation, such as synchronizing with the base station (S601). To this end, the terminal receives a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS) from the base station to synchronize with the base station and obtain information such as a cell identifier (ID). Subsequently, the terminal receives a Physical Broadcast Channel (PBCH) from the base station to obtain broadcast information within the cell. Meanwhile, during the initial cell search phase, the terminal receives a Downlink Reference Signal (DL RS) to check the downlink channel status.

[0105] A terminal that has completed initial cell search can obtain more specific system information by receiving a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH) according to the information carried on the PDCCH (S602).

[0106] Meanwhile, when a terminal first connects to a base station or when there are no wireless resources available for signal transmission, the terminal may perform a Random Access Procedure (RACH) with respect to the base station (steps S603 to S606). To do this, the terminal transmits a specific sequence as a preamble through a Physical Random Access Channel (PRACH) (S603 and S605), and may receive a response message for the preamble through a PDCCH and a corresponding PDSCH (S604 and S606). In the case of a contention-based RACH, a Contention Resolution Procedure may additionally be performed.

[0107] A terminal that has performed the procedure described above may subsequently 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) through the PDCCH. Here, the DCI includes control information such as resource allocation information for the terminal, and its format varies depending on its purpose of use.

[0108] Meanwhile, control information transmitted by the terminal to the base station via the uplink or received by the terminal 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 case of a 3GPP LTE system, the terminal may transmit the aforementioned control information, such as CQI / PMI / RI, via PUSCH and / or PUCCH.

[0109] Table 5 shows an example of the DCI format in an NR system.

[0111] Referring to Table 5, DCI formats 0_0, 0_1, and 0_2 may include resource information related to PUSCH scheduling (e.g., UL / SUL (Supplementary UL), frequency resource allocation, time resource allocation, frequency hopping, etc.), information related to Transport Blocks (TB: Transport Block) (e.g., MCS (Modulation Coding and Scheme), NDI (New Data Indicator), RV (Redundancy Version), etc.), information related to Hybrid - Automatic Repeat and request (e.g., process number, DAI (Downlink Assignment Index), PDSCH-HARQ feedback timing, etc.), information related to multiple antennas (e.g., DMRS sequence initialization information, antenna port, CSI request, etc.), and power control information (e.g., PUSCH power control, etc.), and the control information included in each DCI format may be predefined.

[0112] DCI format 0_0 is used for PUSCH scheduling in a cell. The information contained in DCI format 0_0 is transmitted after being scrambled by CRC (cyclic redundancy check) by C-RNTI (Cell RNTI: Cell Radio Network Temporary Identifier), CS-RNTI (Configured Scheduling RNTI), or MCS-C-RNTI (Modulation Coding Scheme Cell RNTI).

[0113] DCI format 0_1 ​​is used to instruct a terminal on the scheduling of one or more PUSCHs in a cell, or on configured grant (CG) downlink feedback information. The information contained in DCI format 0_1 ​​is transmitted after being CRC scrambled by C-RNTI, CS-RNTI, SP-CSI-RNTI (Semi-Persistent CSI RNTI), or MCS-C-RNTI.

[0114] DCI format 0_2 is used for scheduling PUSCH in a single cell. The information contained in DCI format 0_2 is transmitted after being CRC scrambled by C-RNTI, CS-RNTI, SP-CSI-RNTI, or MCS-C-RNTI.

[0115] Next, DCI formats 1_0, 1_1, and 1_2 may 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.), and the control information included in each DCI format may be predefined.

[0116] DCI format 1_0 is used for scheduling PDSCH in a single DL cell. The information contained in DCI format 1_0 is transmitted after being CRC scrambled by C-RNTI, CS-RNTI, or MCS-C-RNTI.

[0117] DCI format 1_1 is used for scheduling PDSCH in a single cell. The information contained in DCI format 1_1 is transmitted after being CRC scrambled by C-RNTI, CS-RNTI, or MCS-C-RNTI.

[0118] DCI format 1_2 is used for PDSCH scheduling in a single cell. The information contained in DCI format 1_2 is transmitted after being CRC scrambled by C-RNTI, CS-RNTI, or MCS-C-RNTI.

[0119] Downlink semi-persistent scheduling (SPS)

[0120] Downlink SPS combines persistent scheduling via upper-layer signaling (such as RRC) with dynamic scheduling via lower-layer signaling (such as DCI). Persistent scheduling is used for periodic resource allocation for the first transmission of a transport block (TB). Dynamic scheduling is used for resource allocation for retransmission when a retransmission is required.

[0121] Continuous scheduling via upper-layer signaling (RRC, etc.) can be transmitted prior to dynamic scheduling via lower-layer signaling (DCI, etc.).

[0122] The terminal can report SPS support to the base station using the downlinkSPS flag in the UE capability information.

[0123] For SPS, RRC signaling and physical layer signaling over PDCCH are combined and utilized. RRC signaling (e.g., SPS-Config IE) provides a subset of resource allocation information, and additional information is provided by PDCCH. Furthermore, PDCCH is used as a trigger for activation and release.

[0124] Table 6 shows an example of an SPS-Config IE. An SPS-Config IE is used to configure downlink semi-persistent transmission. Multiple downlink SPS configurations can be configured within a single BWP of a serving cell.

[0125] -- ASN1START-- TAG-SPS-CONFIG-STARTSPS-Config ::= SEQUENCE {periodicity ENUMERATED {ms10, ms20, ms32, ms40, ms64, ms80, ms128, ms160, ms320, ms640,spare6, spare5, spare4, spare3, spare2, spare1},nrofHARQ-Processes INTEGER (1..8),n1PUCCH-AN PUCCH-ResourceId OPTIONAL, -- Need Mmcs-Table ENUMERATED {qam64LowSE} OPTIONAL, -- Need S...,[[sps-ConfigIndex-r16 SPS-ConfigIndex-r16 OPTIONAL, -- Cond SPS-Listharq-ProcID-Offset-r16 INTEGER (0..15) OPTIONAL, -- Need RperiodicityExt-r16 INTEGER (1..5120) OPTIONAL, -- Need Rharq-CodebookID-r16 INTEGER (1..2) OPTIONAL, -- Need Rpdsch-AggregationFactor-r16 ENUMERATED {n1, n2, n4, n8} OPTIONAL -- Need S]]}-- TAG-SPS-CONFIG-STOP-- ASN1STOP

[0126] In Table 6, periodicity represents the period of the downlink SPS, which refers to the time interval between consecutive continuous resource allocations. periodicityExt is used to calculate the period of the downlink SPS, and if this parameter is not present, periodicity is ignored. The supported values ​​for the SPS period vary depending on the configured subcarrier spacing.

[0127] nrofHARQ-Processes represents the number of HARQ processes configured for downlink SPS. In the case of dynamic resource allocation, the HARQ process identifier is specified within the DCI associated with each resource allocation. However, in downlink SPS, the HARQ process identifier is determined based on the nrofHARQ-Processes value and the periodicity value.

[0128] n1PUCCH-AN represents the HARQ resource of the PUCCH for the downlink SPS. The actual PUCCH-Resource is set according to the value of n1PUCCH-AN, and based on this, the PUCCH resource for transmitting the HARQ ACK to the base station is identified.

[0129] mcs-Table indicates the MCS table used by the terminal for downlink SPS.

[0130] pdsch-AggregationFactor indicates the number of repetitions of SPS PDSCH and can have a value of {1, 2, 4, 8}. If this field is not present, the terminal applies the pdsch-AggregationFactor from PDSCH-Config. That is, the terminal repeatedly receives the same downlink data / transport block (TB: transport block) in consecutive slots.

[0131] When receiving a scheduled PDSCH without transmitting the corresponding PDCCH using SPS-config, the same symbol allocation is applied across consecutive slots according to the configured repetition count (pdsch-AggregationFactor). That is, the terminal repeatedly receives downlink TBs from the same symbol across multiple consecutive slots according to the configured repetition count. When repeated transmission is configured, the PDSCH is limited to a single transmission layer.

[0132] For a PDSCH scheduled without the corresponding PDCCH transmission using SPS-config, the time interval for reception based on the number of repetitions (pdsch-AggregationFactor) is not larger than the period interval derived from the period obtained from SPS-config.

[0133] The redundancy version (rv_id) is determined differently for each TO of the TB. For PDSCHs scheduled without the corresponding PDCCH transmission using SPS-config, the redundancy version indicated by the DCI is assumed to be 0.

[0134] When a terminal configured with SPS at an upper layer receives DCI on the PDCCH, the terminal first validates whether the downlink SPS assignment PDCCH is valid.

[0135] i) The CRC in DCI format is scrambled by CS(Configured Scheduling)-RNTI; and

[0136] ii) The new data indicator (NDI) in the DCI format for TB is set to 0; and

[0137] iii) When validation is for scheduling activation, and when a PDSCH-to-HARQ feedback timing indicator field exists within the DCI format, if the PDSCH-to-HARQ feedback timing indicator field does not provide an applicable value,

[0138] The terminal determines that the downlink SPS assignment PDCCH is valid for enabling / undoing scheduling.

[0139] Next, the terminal validates whether the DCI format is valid as follows.

[0140] If the terminal is provided with a single setting for SPS PDSCH, verification of the DCI format is achieved when all fields of the DCI format are set according to Table 7 or Table 8 below.

[0141] Table 7 provides examples of fields for verifying the activation of a single downlink SPS scheduling when the terminal is provided with a single SPS PDSCH setting within the downlink BWP of the scheduled cell.

[0142] DCI format 1_1HARQ process numbersset to all '0'sRedundancy versionFor the enabled transport block: set to all '0's

[0143] Table 8 illustrates fields for verifying a single downlink SPS scheduling release when the terminal is provided with a single SPS PDSCH setting within the downlink BWP of the scheduled cell.

[0145] When a terminal is provided with one or more SPS PDSCH settings, and the HARQ process number field in the DCI format indicates the activation of the SPS PDSCH settings with a value identical to the index of a specific setting among the one or more SPS PDSCH settings (i.e., sps-ConfigIndex), and the RV (redundancy version) field of the DCI format is set as shown in Table 7 above, verification of the DCI format for SPS PDSCH activation is achieved.

[0146] When a terminal is provided with one or more SPS PDSCH settings, and the HARQ process number field in the DCI format instructs SPS PDSCH deactivation with a value identical to the index of a specific setting among the one or more SPS PDSCH settings (i.e., sps-ConfigDeactivationStateList or sps-ConfigIndex), and the RV, MCS (modulation and coding schemen), and FDRA (frequency domain resource assignment) fields of the DCI format are all set as shown in Table 8, then verification of the DCI format for SPS PDSCH deactivation is achieved.

[0147] Uplink configured grant

[0148] PUSCH configured grants are classified into CG (configured grant) Type 1 and CG Type 2.

[0149] CG Type 1 is fully resource-allocated or released using RRC signaling. When CG Type 1 is configured, the terminal is allocated a set of resources to periodically transmit PUSCH, and PDCCH is requested only when retransmission is necessary. CG Type 1 PUSCH transmission is semi-statically configured to operate upon receiving the upper layer parameter configuredGrantConfig, which includes rrc-ConfiguredUplinkGrant, without detecting a UL grant within the DCI. The terminal can perform PUSCH transmission according to the configured CG Type 1 until additional RRC signaling is reset to the terminal.

[0150] CG Type 2 resource allocation is partially configured using RRC signaling, and activation / deactivation is indicated using PDCCH transmissions. Since PDCCH also provides time and frequency resource allocations, resource allocation may change each time it is activated. CG Type 2 PUSCH transmissions are semi-persistently scheduled by UL grants within a valid activating DCI after receiving the upper layer parameter configuredGrantConfig, which does not include rrc-ConfiguredUplinkGrant.

[0151] Upper-level signaling (RRC, etc.) for a configured grant can be transmitted before lower-level signaling (DCI, etc.) for uplink scheduling.

[0152] One or more CG settings of CG Type 1 and / or CG Type 2 can be simultaneously activated on the active BWP of the serving cell.

[0153] In a PUSCH transmission corresponding to CG Type 1 or CG Type 2, parameters for the PUSCH transmission may be provided by configuredGrantConfig.

[0154] Table 9 shows an example of configuredGrantConfig IE. configuredGrantConfig IE is used to configure uplink transmission without dynamic grants by DCI. The actual uplink grant may be configured by RRC (CG Type 1) or provided via PDCCH (by CS-RNTI) (CG Type 2). Multiple CG configurations may be configured within a single BWP of a serving cell.

[0156] In Table 10, periodicity represents the period for uplink CG transmission, which refers to the time interval between consecutive continuous resource allocations. periodicityExt is used to calculate the period of the uplink CG, and if this parameter is not present, periodicity is ignored. The supported values ​​for the uplink CG period vary depending on the configured subcarrier spacing.

[0157] 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, in the uplink CG, the HARQ process identifier is determined based on the nrofHARQ-Processes value and the periodicity value.

[0158] repK indicates the number of repetitions. That is, it indicates the repetition level for each PUSCH transmission. repK can have one of the values ​​{1, 2, 4, 8}. For CG Type 1, if the pusch-RepTypeIndicator in rrc-ConfiguredUplinkGrant indicates 'pusch-RepTypeB', PUSCH repetition type B is applied; otherwise, PUSCH repetition type A is applied. For CG Type 2, the PUSCH repetition type is determined by the DCI's UL grant. Depending on the configured PUSCH repetition type A or B, the terminal transmits the uplink TB repeatedly for the configured number of repetitions.

[0159] repK-RV represents a redundancy version sequence. repK-RV is set when a repetition is used (i.e., when repK is set to one of {2, 4, 8}).

[0160] resourceAllocation represents a setting of bitmap-based resource allocation type 0 or resource indication value (RIV)-based resource allocation type 1.

[0161] mcs-Table indicates the MCS table used by the terminal for PUSCH where transform precoding is not used, and mcs-TableTransformPrecoder indicates the MCS table used by the terminal for PUSCH where transform precoding is used. transformPrecoder indicates whether transform precoding is enabled for PUSCH.

[0162] rrc-ConfiguredUplinkGrant is a setting for CG Type 1 transmission. If this field does not exist, the terminal uses the UL grant configured by the DCI via CS-RNTI (i.e., CG Type 2). timeDomainAllocation specifies the start symbol and length of the PUSCH and the PUSCH mapping type. timeDomainOffset indicates the offset associated with the reference SFN (system frame number) specified by timeReferenceSFN. timeReferenceSFN specifies the SFN used to determine the offset of a resource in the time domain. The terminal uses the SFN closest to the specified number prior to receiving the configured grant setting, and if this field does not exist, the reference SFN is 0.

[0163] When a terminal configured with a grant at the upper layer receives DCI on the PDCCH, the terminal first validates whether the configured UL grant Type 2 PDDCH is valid.

[0164] i) The CRC in DCI format is scrambled by CS(Configured Scheduling)-RNTI; and

[0165] ii) The new data indicator (NDI) in the DCI format for TB is set to 0; and

[0166] iii) When validation is for scheduling activation, and when a PDSCH-to-HARQ feedback timing indicator field exists within the DCI format, if the PDSCH-to-HARQ feedback timing indicator field does not provide an applicable value,

[0167] The terminal determines that the configured UL grant Type 2 PDDCH is valid for enabling / disabling scheduling.

[0168] Next, the terminal validates whether the DCI format is valid as follows.

[0169] If the terminal is provided with a single setting for UL grant Type 2 PUSCH, verification of the DCI format is achieved when all fields of the DCI format are set according to Table 11 or Table 12 below.

[0170] Table 11 provides examples of fields for verifying the activation of a single UL grant Type 2 scheduling when the terminal is provided with a single UL grant Type 2 setting within the uplink BWP of the scheduled cell.

[0171] DCI format 0_0 / 0_1 / 0_2HARQ process numberset to all '0'sRedundancy versionset to all '0's

[0172] Table 12 provides examples of fields for verifying the release of a single UL grant Type 2 scheduling when the terminal is provided with a single UL grant Type 2 setting within the uplink BWP of the scheduled cell.

[0174] When a terminal is provided with one or more UL grant Type 2 PUSCH settings, and the HARQ process number field in the DCI format indicates the activation of the UL grant Type 2 PUSCH settings with a value identical to the index of a specific setting among the one or more UL grant Type 2 PUSCH settings (i.e., ConfiguredGrantConfigIndex), and the RV (redundancy version) field of the DCI format is set as shown in Table 11 above, verification of the DCI format for activating UL grant Type 2 PUSCH is achieved.

[0175] When a terminal is provided with one or more UL grant Type 2 PUSCH settings, and the HARQ process number field in the DCI format indicates the release of the UL grant Type 2 PUSCH settings with a value identical to the index of a specific setting among the one or more UL grant Type 2 PUSCH settings (i.e., ConfiguredGrantConfigType2DeactivationStateList or ConfiguredGrantConfigIndex), and when the RV, MCS (modulation and coding schemen), and FDRA (frequency domain resource assignment) fields of the DCI format are all set as shown in Table 12, verification of the DCI format for UL grant Type 2 PUSCH release is achieved.

[0176] When a terminal is scheduled by DCI to transmit a TB over PUSCH, the 'Time domain resource assignment' field value of the UL grant in DCI provides the row value of the resource allocation table.

[0177] Each row of the resource allocation table defines parameters for time domain resource allocation, specifically defining the slot offset (K_2) to be applied to the PUSCH transmission, the start and length indicator (SLIV) (or directly the start symbol (S) and allocation length (L)), the PUSCH mapping type, and the number of repetitions (if numberOfRepetitions exists).

[0178] The resource allocation table may be set by the upper-level parameter PUSCH-TimeDomainResourceAllocationList, or it may be a predefined table.

[0179] The PUSCH-TimeDomainResourceAllocationList (i.e., resource allocation table) contains one or more PUSCH-TimeDomainResourceAllocation IEs. The PUSCH-TimeDomainResourceAllocation IE is used to establish time domain relationships between PDCCH and PUSCH and to set parameters for the aforementioned time domain resource allocation. A value of 0 in the 'Time domain resource assignment' field within the DCI represents the first element in the list (TimeDomainResourceAllocation) (i.e., the first row of the resource allocation table), a value of 1 represents the second element in the list, and so on.

[0180] Wake-up signal (WUS)

[0181] In MTC and NB-IoT, a WUS can be used to reduce power consumption associated with paging monitoring. A WUS is a physical layer signal that indicates whether a terminal should monitor paging signals (e.g., MPDCCH / NPDCCH scrambled with P-RNTI) depending on the cell configuration. For terminals where eDRX is not configured (i.e., only DRX is configured), the WUS can be associated with a single PO (N=1). Conversely, for terminals where eDRX is configured, the WUS can be associated with one or more POs (N≥1). If the WUS is detected, the terminal can monitor the subsequent N POs associated with the WUS. On the other hand, if the WUS is not detected, the terminal can maintain sleep mode by skipping PO monitoring until monitoring the next WUS.

[0182] FIG. 7 illustrates the timing relationship between the WUS and the PO in a wireless communication system to which the present disclosure can be applied.

[0183] The terminal receives configuration information for the WUS from the base station and can monitor the WUS based on the WUS configuration information. The configuration information for the WUS may include, for example, the maximum WUS duration, the number of consecutive POs associated with the WUS, gap information, etc. The maximum WUS duration represents the maximum time interval during which the WUS can be transmitted and can be expressed as a ratio to the maximum number of repetitions (e.g., Rmax) associated with the PDCCH (e.g., MPDCCH, NPDCCH). The terminal can expect repeated WUS transmissions within the maximum WUS duration, but the actual number of WUS transmissions may be less than the maximum number of WUS transmissions within the maximum WUS duration. For example, the number of WUS repetitions may be low for a terminal within good coverage. For convenience, the resources / opportunities for transmitting the WUS within the maximum WUS duration are referred to as WUS resources. WUS resources can be defined as multiple consecutive OFDM symbols and multiple consecutive subcarriers. A WUS resource can be defined as multiple consecutive OFDM symbols and multiple consecutive subcarriers within a subframe or slot. For example, a WUS resource can be defined as 14 consecutive OFDM symbols and 12 consecutive subcarriers. A terminal that detects a WUS does not monitor the WUS until the first PO associated with the WUS. If the WUS is not detected during the maximum WUS interval, the terminal does not monitor paging signals at the POs associated with the WUS (or remains in sleep mode).

[0184] Method for Handling Measurement Gap for Periodic Resource Allocation

[0185] The present disclosure proposes a method for adapting periodic resource allocation (e.g., SPS resources and / or CG resources) and transmission / reception operations according to a measurement gap.

[0186] To this end, the method proposed in this disclosure may include a method for a base station to allocate SPS radio resources to a terminal, and a method for receiving (by the terminal) and transmitting (by the base station) SPS resources. It may also include a method for receiving the base station's retransmission DCI via PDCCH after transmitting a HARQ-ACK PUCCH response for the SPS PDSCH reception result. Additionally, the proposed method may include a process in which the terminal transmits a signal and channel to indicate its capability and / or service requirements, and the base station receives them.

[0187] The method proposed in this disclosure may be applied by selecting or combining one or more of the following embodiments. Additionally, the methods proposed in each embodiment may operate independently without separate combination, or the methods of one or more embodiments may operate in a combined and linked manner. Some terms, symbols, sequences, etc., used to describe the method proposed in this disclosure may be replaced with other terms, symbols, sequences, etc., as long as the principle of the proposed method is maintained.

[0188] In the following description of the present disclosure, SPS / CG may be interpreted as having the same meaning as SPS and / or CG. Additionally, SPS transmission / reception may be interpreted as SPS PDSCH transmission / reception, and SPS (PDSCH) occasion transmission / reception may be interpreted as transmitting and receiving SPS PDSCH on the corresponding SPS (PDSCH) occasion. Likewise, CG transmission / reception may be interpreted as CG PUSCH transmission / reception, and CG (PUSCH) occasion transmission / reception may be interpreted as transmitting and receiving CG PUSCH on the corresponding CG occasion.

[0189] Additionally, in the description of the present disclosure, SPS (PDSCH) occasion and / or CG (PUSCH) occasion may refer to periodic resource allocations and are referred to as SPS (PDSCH) occasion and / or CG (PUSCH) occasion for convenience of explanation.

[0190] Example 1A: A base station and a terminal can perform transmission and reception of SPS PDSCH or CG PUSCH by changing the location of an SPS PDSCH occasion or a CG PUSCH occasion of a specific SPS / CG setting based on a measurement gap.

[0191] When a specific measurement gap is activated or set according to instructions / settings of a base station through an RRC message, MAC CE (control element), or DCI, the terminal can change or skip the activated specific SPS / CG setting location (i.e., SPS / CG occasion location) to perform transmission and reception of SPS PDSCH and / or CG PUSCH.

[0192] Here, the specific measurement gap and / or specific SPS / CG setting may be set by an RRC message or set / instructed by the DCI (or MAC CE). Here, the terminal may receive the RRC message or the DCI (or MAC CE) prior to the specific measurement gap.

[0193] In addition, the specific SPS / CG setting may be mapped / associated with the specific measurement gap. This mapping / associated relationship may be indicated / established by the base station via an RRC message, MAC CE, or DCI. Alternatively, the specific SPS / CG setting may be mapped / associated with the specific measurement gap based on predefined rules, etc.

[0194] For example, if one or more SPS / CG occasions set by the specific SPS / CG setting above overlap with the measurement gap interval (i.e., cases where the entire overlap applies, and cases where a part of the SPS / CG overlaps with the measurement gap interval), the terminal can determine that the location of the SPS / CG occasion has changed as follows and perform transmission and reception of SPS PDSCH and / or CG PUSCH.

[0195] - Option 1: The location of the SPS / CG occasion may be changed or skipped according to the specified rule or RRC setting rule.

[0196] In the case where there are multiple SPS / CG occasions to be moved (i.e., their positions changed) due to overlapping in the measurement gap interval, the positions of the multiple SPS / CG occasions may be changed so that the last SPS / CG occasion, the first SPS / CG occasion, or a specific SPS / CG occasion among them is moved (positioned) to a subsequent slot by an offset (interval) from the last end of the measurement gap interval. Alternatively, the positions of the first or last SPS / CG occasion among them, or only one SPS / CG occasion, may be changed so that it is moved to a previous slot by an offset from the first slot of the measurement gap interval.

[0197] Alternatively, SPS / CG occasion(s) that overlap with the measurement gap interval may be invalidated / skipped so that transmission and reception of SPS PDSCH and / or CG PUSCH are not performed during said SPS / CG occasion(s).

[0198] - Option 2: The location of the SPS / CG occasion can be changed or skipped via DCI (or MAC CE).

[0199] A DCI (or MAC CE) may be received before or after the measurement gap, and the received DCI (or MAC CE) may indicate an offset value. In this case, the position of one or more overlapping SPS / CG occasions may be changed to an earlier slot by an offset from the first slot of the measurement gap, or the position of one or more overlapped SPS / CG occasions may be changed to an later slot by an offset from the last slot of the measurement gap.

[0200] Alternatively, in accordance with instructions from the received DCI (or MAC CE), one or more SPS / CG occasion(s) that overlap with subsequent measurement gap intervals may be invalidated / skipped so that transmission and reception of SPS PDSCH and / or CG PUSCH are not performed during the said SPS / CG occasion.

[0201] - Option 3A: Instructs the change of position or skipping of the Mth (M is an integer greater than N) SPS PDSCH occasion from the Nth (N is an integer greater than 0) SPS PDSCH occasion.

[0202] The Nth SPS PDSCH occasion is received prior to the measurement gap interval, and an offset value may be indicated in the DCI or MAC CE embedded in the received SPS PDSCH. In this case, the position of one or more overlapping SPS occasions may be changed to an earlier slot by an offset from the first slot of the measurement gap interval, or the position of one or more overlapping SPS occasions may be changed to a later slot by an offset from the last slot of the measurement gap interval.

[0203] Alternatively, if the Nth SPS PDSCH occasion is received prior to the measurement gap interval, and the DCI or MAC CE embedded in the received SPS PDSCH indicates a skip, the SPS / CG occasions that overlap with one or more subsequent measurement gap intervals may be invalidated / skipped, so that the transmission and reception of SPS PDSCH and / or CG PUSCH at the said SPS / CG occasions may not be performed.

[0204] Option 3B: Instructs the change of position or skipping of the Mth (M is an integer greater than N) CG PUSCH occasion from the Nth (N is an integer greater than 0) CG PUSCH occasion.

[0205] Before or during the measurement gap period, the terminal transmits a UCI or MAC CE / RRC message embedded in the CG PUSCH and may indicate an offset value in the transmitted UCI / MAC CE / RRC message. The position of one or more overlapping CG occasions may be changed to an earlier slot by an offset from the first slot of the measurement gap period, or the position of one or more overlapping CG occasions may be changed to a later slot by an offset from the last slot of the measurement gap period or the slot in which the UCI / MAC CE / RRC message is transmitted.

[0206] Alternatively, the terminal may transmit a UCI or MAC CE / RRC message embedded in the CG PUSCH before or during the measurement gap period, and may indicate a skip in the transmitted UCI / MAC CE / RRC message. Subsequently, overlapping SPS / CG occasions may be invalidated / skipped during one or more measurement gap periods, so that the transmission and reception of the corresponding SPS PDSCH and / or CG PUSCH are not performed.

[0207] In the description above, UCI may be an unused transmission occasion (UTO)—UCI, and may refer to uplink control information indicating an unused transmission occasion.

[0208] Example 1B: Method for indicating SPS / CG adaptation information within a measurement gap interval

[0209] - Method A1: When N (N is an integer greater than 0) SPS occasions overlap within a specific measurement gap interval, the terminal can receive SPS PDSCH by changing the number of SPS occasions within the specific measurement gap interval to M (M is an integer greater than 0) as follows. Here, the interval between SPS occasions may be changed. For example, if N > M, the terminal can receive SPS PDSCH by changing the SPS occasion positions so that the interval between SPS occasions within the measurement gap interval is increased by an offset.

[0210] Option 1: SPS occasion location(s) may be changed according to specified rules or RRC setting rules.

[0211] For example, the M value may be set by the RRC setting of the base station prior to a specific measurement gap, or an offset that is the interval may be set.

[0212] Option 2: The SPS occasion location(s) may be changed at the direction of the DCI (or MAC CE).

[0213] For example, a base station may indicate a value of M at a specific DCI (or MAC CE) before or during a specific measurement gap interval, or indicate an offset which is the interval. Here, the CRC of the specific DCI may be scrambled into a C-RNTI, a CS-RNTI, or a specific RNTI.

[0214] Option 3: Can instruct the change of position of the Pth SPS PDSCH occasion at the Qth SPS PDSCH occasion.

[0215] For example, the M value may be indicated in the DCI or MAC CE embedded (associated / embedded) in the Qth SPS PDSCH received prior to or during a specific measurement gap interval, or the offset which is the interval may be indicated.

[0216] - Method A2: When N (N is an integer greater than 0) CG occasions overlap within a specific measurement gap interval, the terminal may transmit a CG PUSCH by changing the number of CG occasions within the specific measurement gap interval to M (M is an integer greater than 0) as follows. Here, the interval between CG occasions may be changed. For example, if N > M, the terminal may transmit a CG PUSCH by changing the CG occasion positions so that the interval between CG occasions within the specific measurement gap interval is increased by an offset.

[0217] Option 1: The CG occasion location(s) may be changed according to the specified rule or RRC setting rule.

[0218] For example, the M value may be set by the RRC setting of the base station prior to a specific measurement gap, or an offset that is the interval may be set.

[0219] Option 2: The CG occasion location(s) may be changed at the direction of the DCI (or MAC CE).

[0220] For example, a base station may indicate a value of M at a specific DCI (or MAC CE) before or during a specific measurement gap interval, or indicate an offset which is the interval. Here, the CRC of the specific DCI may be scrambled into a C-RNTI, a CS-RNTI, or a specific RNTI.

[0221] Option 3: You can instruct the change of the position of the Pth CG PUSCH occasion in the Qth CG PUSCH occasion.

[0222] For example, the M value may be indicated in the UCI (e.g., UTO-UCI) or MAC CE embedded in the Qth CG PUSCH received prior to or during a specific measurement gap interval, or the offset which is the interval may be indicated.

[0223] - Method B1: One or more SPS settings are grouped / associated with a single index, and SPS PDSCH occasions for specific SPS setting(s) that overlap with a specific measurement gap interval may be shifted later or earlier in the time domain depending on the setting index value or the HARQ process number (HPN) value corresponding to the index.

[0224] The base station transmits an RRC message to the terminal, and the terminal can be configured to map SPS setting 1 and SPS setting 2 to the same setting index value or HPN value = k.

[0225] If a terminal according to the above settings receives a DCI (or MAC CE) indicating k, and the DCI (or MAC CE) indicates +m slots, the terminal may determine / consider that all SPS PDSCH occasions allocated after the offset from the slot where the DCI (or MAC CE) was received have moved m slots later. Here, the offset is 0 or a positive integer. For example, the terminal may receive SPS PDSCH by determining / consider that the SPS PDSCH occasion of slot n has moved to slot n+m.

[0226] If the corresponding DCI (or MAC CE) indicates -m slots, it is determined that all SPS PDSCH occasions assigned after the DCI (or MAC CE) have moved back by m slots. For example, a terminal may receive the SPS PDSCH by determining / considering that the SPS PDSCH occasion of slot n has moved to slot nm. Here, the CRC of the DCI can be scrambled with CS-RNTI, C-RNTI, or a specific RNTI.

[0227] According to the conventional method, when changing the location of an SPS resource, it was necessary to deactivate it via RRC or DCI and then reactivate it. According to the proposed method above, the location of one or more SPS resources can be changed with a single DCI transmission.

[0228] In this manner, it may be determined that the SPS occasion is moved only when the terminal transmits an ACK that has received the DCI (or MAC CE), and it may be determined that the SPS occasion is not moved when the terminal transmits a NACK. Here, when the terminal transmits an ACK, all SPS occasions allocated after the offset from the slot where the ACK for the DCI (or MAC CE) was transmitted may be determined / considered to have moved.

[0229] The above specific measurement gap and / or specific SPS setting may be set by an RRC message or indicated by the DCI (or MAC CE). Here, the terminal may receive the RRC message or the DCI (or MAC CE) prior to the specific measurement gap.

[0230] - Method B2: One or more CG settings are grouped / associated with a single index, and CG PDSCH occasions for specific CG setting(s) that overlap with a specific measurement gap interval can be shifted later or earlier in the time domain depending on the setting index value or the HPN value corresponding to the index.

[0231] The base station transmits an RRC message to the terminal, and the terminal can be configured to map CG setting 1 and CG setting 2 to the same setting index value or HPN value = k.

[0232] If a terminal according to the above settings receives a DCI (or MAC CE) indicating k, and the DCI (or MAC CE) indicates +m slots, the terminal may determine / consider that all CG PUSCH occasions allocated after the offset from the slot where the DCI (or MAC CE) was received have moved m slots later. Here, the offset is 0 or a positive integer. For example, the CG PUSCH occasion of slot n may be determined / considered to have moved to slot n+m and transmit a CG PUSCH.

[0233] If the corresponding DCI (or MAC CE) indicates -m slots, it is determined that all CG PUSCH occasions assigned after the DCI (or MAC CE) have moved back by m slots. For example, the terminal may determine / consider that the CG PUSCH occasion of slot n has moved to slot nm and transmit a CG PUSCH. Here, the CRC of the DCI can be scrambled with CS-RNTI, C-RNTI, or a specific RNTI.

[0234] According to the conventional method, when changing the location of a CG resource, it was necessary to deactivate it via RRC or DCI and then reactivate it. According to the proposed method, the location of one or more CG resources can be changed with a single DCI transmission.

[0235] In this manner, the terminal may be determined to move the CG occasion only when it transmits an ACK that has received the DCI (or MAC CE), and may be determined not to move the CG occasion when the terminal transmits a NACK. Here, when the terminal transmits an ACK, all CG occasions allocated after the offset from the slot where the ACK for the DCI (or MAC CE) was transmitted may be determined / considered to have moved.

[0236] The specific measurement gap and / or specific CG configuration may be set by an RRC message or indicated by the DCI (or MAC CE). Here, the terminal may receive the RRC message or the DCI (or MAC CE) prior to the specific measurement gap.

[0237] Example 2: Based on the measurement gap, the number of CG occasions from cell DRX1 to cell DRX2 can be relaxed.

[0238] The terminal can adjust the period of CG PUSCH occasions for specific CG setting(s) according to the measurement gap (e.g., significantly change the period) or skip CG PUSCH occasions at regular intervals.

[0239] Here, the specific CG setting may be mapped / associated with the specific measurement, and this mapping / associated relationship may be indicated / established by the base station through an RRC message, MAC CE, or DCI.

[0240] For example, for a specific CG setting, the terminal may assign a CG PUSCH occasion at short intervals (e.g., 10ms) outside a specific measurement gap interval and assign a CG PUSCH occasion at long intervals (e.g., 40ms) within a specific measurement gap interval.

[0241] Accordingly, the base station can receive CG PUSCH occasions at short intervals (e.g., 10ms) within a specific measurement gap interval and at long intervals (e.g., 40ms) outside the specific measurement gap interval.

[0242] Alternatively, the terminal may be configured to allocate CG PUSCH occasions at short intervals (e.g., 10ms) for a specific CG setting according to the base station's settings. Here, if a specific measurement gap is also configured, the terminal may determine that CG PUSCH occasions are valid at short intervals (e.g., 10ms) outside the specific measurement gap interval (i.e., all CG PUSCH occasions are valid), and that CG PUSCH occasions are valid at long intervals (e.g., 40ms) within the specific measurement gap interval. Additionally, the terminal may determine that the remaining CG PUSCH occasions between the valid CG PUSCH occasions are invalid.

[0243] The terminal can determine a specific measurement gap interval and the above-mentioned activation / inactivation according to the instructions of the base station's DCI, the instructions of the MAC CE, or the RRC settings.

[0244] The base station can receive CG PUSCH occasions at short intervals (e.g., 10ms) outside a specific measurement gap interval and at long intervals (e.g., 40ms) within a specific measurement gap interval.

[0245] Example 3: Method for changing or skipping the location of a specific plurality of SPS / CG settings included in a measurement gap interval by a specific DCI (or MAC CE) indication

[0246] The terminal receives a specific DCI (or MAC CE) from a base station and can transmit and receive SPS PDSCH and / or CG PUSCH by changing or skipping the location of one or more specific SPS / CG settings included in the measurement gap interval based on the specific DCI (or MAC CE) instruction.

[0247] The above specific DCI (or MAC CE) may correspond to a DCI (or MAC CE) received prior to the measurement gap, and the above specific DCI (or MAC CE) may instruct to change or skip the location of a specific one or more SPS / CG settings. Accordingly, the terminal transmits and receives by changing or skipping the location of a specific multiple SPS / CG settings in accordance with the instruction of the specific DCI (or MAC CE).

[0248] The specific DCI (or MAC CE) above may indicate the index or ID (identifier) ​​of the measurement gap, and may indicate the index (or ID) of the SPS / CG setting, whether to skip, or the offset m value.

[0249] If a specific DCI (or MAC CE) has indicated a skip, the reception of all SPS PDSCH occasions of the SPS setting indicated by the DCI (or MAC CE) that overlap with the measurement gap that occurred after the slot in which the DCI (or MAC CE) was received, or the reception of all SPS PDSCH occasions of the SPS setting indicated by the DCI (or MAC CE) that overlap with the measurement gap indicated by the specific DCI (or MAC CE) may be skipped, or all SPS PDSCH occasions of the SPS setting indicated by the DCI (or MAC CE) that overlap may be invalidated.

[0250] If a specific DCI (or MAC CE) has indicated a skip, transmissions in all CG PUSCH occasions of the CG setting indicated by the DCI (or MAC CE) that overlap with the measurement gap that occurred after the slot in which the DCI (or MAC CE) was received, or the measurement gap indicated by the specific DCI (or MAC CE), may be skipped, or all CG PUSCH occasions of the CG setting indicated by the DCI (or MAC CE) that overlap may be invalidated.

[0251] If a specific DCI (or MAC CE) indicates +m slots, all SPS PDSCH occasions or all CG PUSCH occasions allocated after the offset from the slot receiving the DCI (or MAC CE) may be determined / considered to have moved m slots later. Here, the offset is 0 or a positive integer. For example, an SPS PDSCH occasion or CG PUSCH occasion of slot n may be determined / considered to have moved to slot n+m, and an SPS PDSCH and / or CG PUSCH may be transmitted.

[0252] If a specific DCI (or MAC CE) indicates -m slots, all SPS PDSCH occasions assigned after the slot in which the DCI (or MAC CE) was received may be determined / considered to have moved back by m slots. For example, an SPS PDSCH occasion or CG PUSCH occasion of slot n may be determined / considered to have moved to slot nm, and an SPS PDSCH and / or CG PUSCH may be transmitted.

[0253] In the above description, the CRC of the DCI can be scrambled into CS-RNTI, C-RNTI, or a specific RNTI.

[0254] Example 4: Method for reporting whether SPS PDSCH occasion(s) can be received or CG PUSCH occasion(s) can be transmitted during a measurement gap interval

[0255] The terminal may report whether SPS PDSCH occasion(s) are available to receive or CG PUSCH occasion(s) are available to transmit in the measurement gap via UCI, MAC CE, or RRC messages.

[0256] When a terminal reports whether it is possible to receive SPS PDSCH occasion(s) in the measurement gap interval via a UCI, MAC CE, or RRC message of a dynamically allocated PUSCH or CG PUSCH, the base station receives the report and can determine whether to transmit the SPS PDSCH occasion(s) based on the reported information.

[0257] If the terminal reports that it is possible to receive SPS PDSCH occasion(s) during the measurement gap period, the base station transmits the active SPS PDSCH occasion(s) during the measurement gap period, and the terminal can receive the said SPS PDSCH occasion(s). If the terminal reports that it is impossible to receive SPS PDSCH occasion(s) during the measurement gap period, the base station does not transmit the active SPS PDSCH occasion(s) during the measurement gap period, and the terminal may not receive the said SPS PDSCH occasion(s).

[0258] Here, when the availability of receiving SPS PDSCH occasion(s) is reported to UCI, the transmission of the corresponding SPS PDSCH occasion(s) may be determined for one, N, or all measurement gap intervals that occur after the UCI transmission slot + offset.

[0259] Alternatively, if the availability of an SPS PDSCH occasion(s) is reported by a MAC CE or RRC message, the transmission of the SPS PDSCH occasion(s) may be determined for one, N, or all measurement gap intervals that occur after the MAC CE or RRC message transmission slot + offset. Alternatively, the transmission of the SPS PDSCH occasion(s) may be determined for one, N, or all measurement gap intervals that occur after the transmission of a HARQ ACK or RLC ACK for the MAC CE or RRC message.

[0260] A report on the reception availability of the above SPS PDSCH occasion(s) may indicate a specific measurement gap. For example, the report may include information on a measurement gap ID or index, or on the serving cell or serving frequency to which the measurement gap applies.

[0261] In addition, if the terminal reports whether transmission of CG PUSCH occasion(s) is possible during the measurement gap period via a UCI, MAC CE, or RRC message of a dynamically allocated PUSCH or CG PUSCH, the base station receives the report and can determine whether to receive the CG PUSCH occasion(s) based on the reported information.

[0262] If the terminal reports that it is possible to transmit CG PUSCH occasion(s) during the measurement gap period, the terminal may transmit the active CG PUSCH occasion(s) during the measurement gap period. If the terminal reports that it is not possible to transmit CG PUSCH occasion(s) during the measurement gap period, the terminal may not transmit the active CG PUSCH occasion(s) during the measurement gap period.

[0263] Here, if the transmission availability of CG PUSCH occasion(s) is reported to UCI, the transmission availability of the CG PUSCH occasion(s) may be determined for one, N, or all measurement gap intervals that occur after the UCI transmission slot + offset.

[0264] Alternatively, if the transmission availability of a CG PUSCH occasion(s) is reported by a MAC CE or RRC message, the transmission of the CG PUSCH occasion(s) may be determined for one, N, or all measurement gap intervals that occur after the MAC CE or RRC message transmission slot + offset. Alternatively, the transmission of the CG PUSCH occasion(s) may be determined for one, N, or all measurement gap intervals that occur after the transmission of a HARQ ACK or RLC ACK for the MAC CE or RRC message.

[0265] A report on the transmission availability of the above CG PUSCH occasion(s) may indicate a specific measurement gap. For example, the report may include information on a measurement gap ID or index, or on the serving cell or serving frequency to which the measurement gap applies.

[0266] Example 5: The transmission or reception of the next CG / SPS occasion may be indicated by the previous CG / SPS occasion.

[0267] The terminal can indicate whether to transmit the Mth (M is an integer greater than N) CG PUSCH that overlaps with the next measurement gap interval by transmitting the Nth (N is an integer greater than 0) CG PUSCH that does not overlap with the measurement gap interval.

[0268] In this case, the terminal may transmit or not transmit the Mth CG PUSCH transmission indicated by the Nth CG PUSCH even if it overlaps with the measurement gap interval.

[0269] The indication for whether to transmit the above Mth CG PUSCH may be indicated by the UTO-UCI associated with the Nth CG PUSCH, by the piggybacked UCI of the Nth CG PUSCH, or by the MAC CE or RRC message included in the transport block (TB) of the Nth CG PUSCH.

[0270] In addition, the instruction regarding whether to transmit the Mth CG PUSCH may include one or more of the following information.

[0271] - For one or more CG PUSCH occasions of a specific CG setting(s) including the Mth CG PUSCH occasion, information on whether to transmit when overlapping with a measurement gap interval for each CG PUSCH occasion may be included.

[0272] For example, each bit of the bitmap can indicate whether to transmit when the measurement gap overlaps with each CG PUSCH occasion from the N+1th to the N+kth CG PUSCH occasion. Here, M can be N+1 or N+k or a value between these.

[0273] The above specific CG setting index(s) may be set as an instruction for whether to transmit the Mth CG PUSCH or as an RRC message.

[0274] - Information regarding transmission of all CG PUSCH occasions of a specific CG setting(s) that overlap with one or more measurement gap(s) occurring after the Nth CG PUSCH may be included.

[0275] For example, information on whether all CG PUSCH occasions that overlap with all measurement gap(s) occurring after the Nth CG PUSCH transmission have been transmitted may be included.

[0276] Alternatively, information regarding the transmission of all CG PUSCH occasions that overlap with Q measurement gap(s) occurring after the Nth CG PUSCH transmission may be included. Here, the Q value may be fixed, set as an RRC message, or set as an indication regarding the transmission of the Mth CG PUSCH. For example, the Q value may be a value greater than or equal to 1.

[0277] The above specific CG setting index(s) may be set as an instruction for whether to transmit the Mth CG PUSCH or as an RRC message.

[0278] Both the Nth CG PUSCH and the Mth CG PUSCH may belong to the specific CG settings mentioned above. If the Nth CG PUSCH does not belong to the specific CG settings mentioned above, the index of the CG settings of the Nth CG PUSCH may be set as an instruction regarding whether to transmit the Mth CG PUSCH or as an RRC message.

[0279] The base station can indicate whether to transmit the Mth (M is an integer greater than N) SPS PDSCH that overlaps with the next measurement gap interval using the Nth (N is an integer greater than 0) SPS PDSCH that does not overlap with the measurement gap interval.

[0280] In this case, the terminal that receives the Nth SPS PDSCH may or may not receive the Mth SPS PDSCH transmission indicated by the Nth SPS PDSCH even if it overlaps with the measurement gap.

[0281] The instruction regarding whether to transmit the Mth SPS PDSCH may be indicated by the piggybacked DCI of the Nth SPS PDSCH, or by the MAC CE or RRC message included in the TB of the Nth SPS PDSCH.

[0282] The instruction regarding whether the above Mth SPS PDSCH is transmitted may include one or more of the following information.

[0283] - For one or more SPS PDSCH occasions of a specific SPS setting(s) including the Mth SPS PDSCH occasion, information on whether to transmit when overlapping with a measurement gap interval for each SPS PDSCH occasion may be included.

[0284] For example, each bit of the bitmap can indicate whether to transmit when the measurement gap overlaps with each SPS PDSCH for the N+1th to N+kth SPS PDSCH occasions. Here, M can be N+1 or N+k or a value between these.

[0285] The index(s) of the specific SPS setting above may be set as an instruction for whether to transmit the Mth SPS PDSCH or as an RRC message.

[0286] - Information regarding transmission of SPS PDSCH occasions of specific SPS setting(s) that overlap with one or more measurement gap(s) occurring after the Nth SPS PDSCH may be included.

[0287] For example, information on whether all SPS PDSCH occasions that overlap with all measurement gap(s) occurring after the Nth SPS PDSCH transmission are transmitted may be included.

[0288] Alternatively, information regarding the transmission of all SPS PDSCH occasions that overlap with Q measurement gap(s) occurring after the Nth SPS PDSCH transmission may be included. Here, the Q value may be fixed, set as an RRC message, or set as an indication regarding the transmission of the Mth SPS PDSCH. For example, the Q value may be a value greater than or equal to 1.

[0289] The index(s) of the specific SPS setting above may be set as an instruction for whether to transmit the Mth SPS PDSCH or as an RRC message.

[0290] Both the Nth SPS PDSCH and the Mth SPS PDSCH may belong to the specific SPS setting mentioned above. If the Nth SPS PDSCH does not belong to the specific SPS setting mentioned above, the index of the SPS setting of the Nth SPS PDSCH may be set as an instruction regarding whether to transmit the Mth SPS PDSCH or as an RRC message.

[0291] Example 6: SPS / CG transmission and reception method in a measurement gap according to LP-WUS (low power-wake-up signal)

[0292] The terminal may monitor the LP-WUS before or during a specific measurement gap interval according to the base station's settings. In this case, the terminal may deactivate a specific SPS setting, suspend or skip the reception of an activated SPS PDSCH of a specific SPS setting, or invalidate the corresponding SPS PDSCH occasions according to the instructions of the LP-WUS.

[0293] Here, specific SPS settings may be set by an RRC message, indicated by a DCI or MAC CE, or indicated by an LP-WUS. In the absence of such settings / instructions, the proposed method for one or more embodiments described above in Examples 1 to 5 may be applied to the terminal or all SPS settings.

[0294] When the above specific measurement gap is deactivated or after the specific measurement gap interval, the terminal may activate the deactivated SPS setting without a separate base station instruction, or resume suspended SPS PDSCH reception. Accordingly, the terminal may activate and receive all activated SPS PDSCH occasions that occurred after the LP-WUS that instructed the wake-up.

[0295] Additionally, if a DCI (or MAC CE) received after a specific measurement gap directs a specific SPS setting, the terminal can activate the directed SPS setting or resume receiving SPS PDSCH. Accordingly, the terminal can activate and receive all activated SPS PDSCH occasions of the specific SPS setting that occurred after the LP-WUS that directed the wake-up.

[0296] The terminal may monitor the LP-WUS before or during a specific measurement gap interval according to the base station's settings. In this case, the terminal may deactivate a specific CG setting, suspend or skip the transmission of an activated CG PUSCH of a specific CG setting, or invalidate the CG PUSCH occasions according to the instructions of the LP-WUS.

[0297] Here, specific CG settings may be set by an RRC message, indicated by DCI or MAC CE, or indicated by LP-WUS. In the absence of such settings / instructions, the proposed method for one or more embodiments described above in Examples 1 to 5 may be applied to the terminal or for all CG settings.

[0298] When the above specific measurement gap is deactivated or after the specific measurement gap period, the terminal may activate the CG setting that was instructed to be deactivated or resume the suspended CG PUSCH transmission without a separate base station instruction. Accordingly, the terminal may activate and transmit all activated CG PUSCH occasions that occurred after the LP-WUS that instructed the wake-up.

[0299] Additionally, if a DCI (or MAC CE) received after a specific measurement gap directs a specific CG setting, the terminal may activate the directed CG setting or resume CG PUSCH transmission. Accordingly, the terminal may activate and transmit all activated CG PUSCH occasions of the specific CG setting that occurred after the LP-WUS directing the wake-up.

[0300] FIG. 8 is a diagram illustrating the operation of a UE for a wireless signal transmission and reception method according to one embodiment of the present disclosure.

[0301] FIG. 8 illustrates the operation of a UE based on the proposed methods in the embodiments described above. The example in FIG. 8 is for convenience of explanation and is not intended to limit the scope of the present disclosure. Some step(s) illustrated in FIG. 8 may be omitted depending on the situation and / or configuration. Also, the UE in FIG. 8 is merely an example and may be implemented as the device illustrated in FIG. 10 below. For example, the processor (102 / 202) of FIG. 10 may control the transmission and reception of channels / signals / data / information, etc. using a transceiver (106 / 206), and may also control the storage of channels / signals / data / information, etc. to be transmitted or received in a memory (104 / 204).

[0302] Additionally, the operation of FIG. 8 may be processed by one or more processors (102, 202) of FIG. 10. Additionally, the operation of FIG. 8 may be stored in memory (e.g., one or more memories (104, 204) of FIG. 10) in the form of an instruction / program (e.g., instruction, executable code) for driving at least one processor (e.g., 102, 202) of FIG. 10.

[0303] Referring to FIG. 8, the UE receives first configuration information related to the configuration of periodic resource allocation for downlink reception or uplink transmission from a base station (S801).

[0304] Here, the periodic resource allocation may be semi-persistent scheduling (SPS) or configured-grant (CG). For example, the first configuration information may be an SPS configuration (SPS-Config) for configuring downlink semi-persistent transmission (see Table 6), and multiple downlink SPS configurations may be configured within a single BWP of the serving cell. Alternatively, the first configuration information may be a CG configuration (ConfiguredGrantConfig) for configuring uplink transmission without dynamic grants according to two possible methods (see Table 9), and the actual uplink grant may be configured via RRC (Type 1) or provided via PDCCH (addressed by CS-RNTI) (Type 2). Multiple configured grant configurations may be configured within a single BWP of the serving cell. Based on the first configuration information, the locations of multiple resource allocations for downlink reception or uplink transmission in the time domain may be determined. For example, the location of resource allocations can be determined in units of slots or symbols.

[0305] The UE receives second configuration information related to the measurement gap from the base station (S802).

[0306] Here, the second configuration information may be a measurement gap configuration (MeasGapConfig) that specifies the measurement gap configuration and controls the setup / unset of the measurement gaps.

[0307] Although not shown in FIG. 8, a UE with one or more measurement gaps set performs measurements at the set measurement gaps.

[0308] The UE performs downlink reception or uplink transmission by changing the location of one or more resource allocations based on the fact that the location of one or more resource allocations among the multiple resource allocations overlaps with the interval of the measurement gap (S803).

[0309] For example, the location of the one or more resource allocations may be changed to an offset earlier from the first slot of the measurement gap interval or to an offset later from the last slot of the measurement gap interval. Here, the offset may be indicated by downlink control information or a low power-wake-up signal (LP-WUS) from the base station or determined according to a predefined rule.

[0310] As another example, the location of the one or more resource allocations may be changed by changing the interval for the one or more resource allocations or by changing the number of the one or more resource allocations. Here, information regarding the interval for the one or more resource allocations or the number of the one or more resource allocations may be set by the base station or determined according to a predefined rule.

[0311] Additionally, the location of one or more resource allocations may be changed based on a HARQ (hybrid automatic repeat and request) process number corresponding to the setting of the periodic resource allocation. In this case, the location of one or more resource allocations after an offset from the reception of the downlink control information may be changed based on the HARQ process number corresponding to the setting of the periodic resource allocation indicated in the downlink control information by the base station.

[0312] Additionally, although not illustrated in FIG. 8, the UE may transmit to the base station a report regarding whether downlink reception or uplink transmission is possible in one or more resource allocations during the interval of the measurement gap. Here, the report may include identification information for the measurement gap or serving cell or frequency information to which the measurement gap applies.

[0313] FIG. 9 is a diagram illustrating the operation of a base station for a wireless signal transmission and reception method according to one embodiment of the present disclosure.

[0314] FIG. 9 illustrates the operation of a base station based on the proposed methods in the embodiments described above. The example in FIG. 9 is for convenience of explanation and does not limit the scope of the present disclosure. Some step(s) illustrated in FIG. 9 may be omitted depending on the situation and / or configuration. Also, the base station in FIG. 9 is merely an example and may be implemented as the device illustrated in FIG. 17 below. For example, the processor (102 / 202) of FIG. 17 may control the transmission and reception of channels / signals / data / information, etc. using a transceiver (106 / 206), and may also control the storage of channels / signals / data / information, etc. to be transmitted or received in a memory (104 / 204).

[0315] Additionally, the operation of FIG. 9 may be processed by one or more processors (102, 202) of FIG. 10. Additionally, the operation of FIG. 9 may be stored in memory (e.g., one or more memories (104, 204) of FIG. 10) in the form of an instruction / program (e.g., instruction, executable code) for driving at least one processor (e.g., 102, 202) of FIG. 10.

[0316] Referring to FIG. 9, the base station transmits first configuration information related to the setting of periodic resource allocation for downlink transmission or uplink reception to the UE (S901).

[0317] Here, the periodic resource allocation may be semi-persistent scheduling (SPS) or configured-grant (CG). For example, the first configuration information may be an SPS configuration (SPS-Config) for configuring downlink semi-persistent transmission (see Table 6), and multiple downlink SPS configurations may be configured within a single BWP of the serving cell. Alternatively, the first configuration information may be a CG configuration (ConfiguredGrantConfig) for configuring uplink transmission without dynamic grants according to two possible methods (see Table 9), and the actual uplink grant may be configured via RRC (Type 1) or provided via PDCCH (addressed by CS-RNTI) (Type 2). Multiple configured grant configurations may be configured within a single BWP of the serving cell. Based on the first configuration information, the locations of multiple resource allocations for downlink reception or uplink transmission in the time domain may be determined. For example, the location of resource allocations can be determined in units of slots or symbols.

[0318] The base station transmits second configuration information related to the measurement gap to the UE (S902).

[0319] Here, the second configuration information may be a measurement gap configuration (MeasGapConfig) that specifies the measurement gap configuration and controls the setup / unset of the measurement gaps.

[0320] Although not shown in FIG. 9, a UE with one or more measurement gaps set performs measurements at the set measurement gaps.

[0321] The base station performs downlink transmission or uplink reception by changing the location of one or more resource allocations based on the fact that the location of one or more resource allocations among a plurality of resource allocations overlaps with the interval of the measurement gap (S903).

[0322] For example, the location of the one or more resource allocations may be changed to an offset earlier from the first slot of the measurement gap interval or to an offset later from the last slot of the measurement gap interval. Here, the offset may be indicated by downlink control information or a low power-wake-up signal (LP-WUS) from the base station or determined according to a predefined rule.

[0323] As another example, the location of the one or more resource allocations may be changed by changing the interval for the one or more resource allocations or by changing the number of the one or more resource allocations. Here, information regarding the interval for the one or more resource allocations or the number of the one or more resource allocations may be set by the base station or determined according to a predefined rule.

[0324] Additionally, the location of one or more resource allocations may be changed based on a HARQ (hybrid automatic repeat and request) process number corresponding to the setting of the periodic resource allocation. In this case, the location of one or more resource allocations after an offset from the reception of the downlink control information may be changed based on the HARQ process number corresponding to the setting of the periodic resource allocation indicated in the downlink control information by the base station.

[0325] Additionally, although not illustrated in FIG. 9, the base station may receive a report from the UE regarding whether downlink reception or uplink transmission is possible in one or more resource allocations during the interval of the measurement gap. Here, the report may include identification information for the measurement gap or serving cell or frequency information to which the measurement gap applies.
