Description

Technical Field

[0001] This disclosure relates to terminals, wireless communication methods, and base stations in next-generation mobile communication systems. Background Technology

[0002] In Universal Mobile Telecommunications System (UMTS) networks, Long Term Evolution (LTE) was standardized with the aim of achieving higher data rates and lower latency (Non-Patent Document 1). Furthermore, LTE-Advanced (3GPP Rel. 10-14) was standardized with the aim of further increasing capacity and improving upon LTE (Third Generation Partnership Project (3GPP (registered trademark)) Release (Rel.) 8, 9).

[0032] (Initial access process)

[0033] During the initial access process, the UE (RRC_IDLE mode) receives the SS / PBCH block (SSB), transmits Msg.1 (PRACH / random access preamble), receives Msg.2 (PDCCH, PDSCH containing the random access response (RAR)), transmits Msg.3 (PUSCH scheduled via RAR UL permission), and receives Msg.4 (PDCCH, PDSCH containing the UE contention resolution identifier). Subsequently, if the UE sends an ACK for Msg.4 to the base station (network), an RRC connection is established (RRC_CONNECTED mode).

[0034] SSB reception includes PSS detection, SSS detection, PBCH-DMRS detection, and PBCH reception. PSS detection detects a portion of the Physical Cell ID (PCI), OFDM symbol timing (synchronization), and (coarse) frequency synchronization. SSS detection includes physical cell ID detection. PBCH-DMRS detection includes detection of a portion of the SSB index within a half-frame (5ms). PBCH reception includes detection of the system frame number (SFN) and radio frame timing (SSB index), reception of remaining minimum system information (RMSI, SIB1) settings, and identification of whether the UE can camp on the cell (carrier).

[0035] The SSB has a 20RB band and a 4-symbol time. The SSB transmission period can be set from {5, 10, 20, 40, 80, 160} ms. In a half-frame, multiple symbol positions of the SSB are specified based on the frequency range (FR1, FR2).

[0036] The PBCH has a 56-bit payload. N repetitions of the PBCH are transmitted within an 80ms period. N depends on the SSB transmission period.

[0037] System information consists of the MIB, RMSI (SIB1), and other system information (OSI) carried via the PBCH. SIB1 contains information for RACH setup and the RACH process. The time / frequency resource relationship between the SSB and SIB1, monitored via the PDCCH, is set through the PBCH.

[0038] The PDSCH carrying SIB1 (SIB1 PDSCH) is transmitted periodically. This PDSCH is scheduled via type 0-PDCCH. One SSB corresponds to one SIB1 PDSCH. An SIB1 PDSCH may be transmitted twice or not. SIB1 sets the Public Land Mobile Network (PLMN) ID. The PLMN ID can also be an MNO identifier.

[0039] Base stations using beam correspondence transmit multiple SSBs separately using multiple beams (simulated beams) per SSB transmission cycle. These multiple SSBs can also be referred to as SSB bursts. Each of these multiple SSBs has multiple SSB indices. A UE that detects an SSB transmits a PRACH at the RACH occasion associated with that SSB index and receives a RAR within the RAR window.

[0040] (SSB: Physical channels and modulation / Downlink / Physical signals / SS / PBCH block)

[0041] Resources used in PSS, SSS, PBCH, and SS / PBCH blocks (SSB) of PBCH using DMRS are defined as follows.

[0042] - PSS:

[0043] -- OFDM symbol number l=0 for the beginning of the SS / PBCH block, and subcarrier number k=56,57,...,182 for the beginning of the SS / PBCH block.

[0046] - Resources set to zero:

[0047] -- OFDM symbol number l=0 for the beginning of the SS / PBCH block, and subcarrier number k=0,1,...,55,183,184,...,239 for the beginning of the SS / PBCH block.

[0048] -- OFDM symbol number l=2 for the beginning of the SS / PBCH block, and subcarrier number k=48,49,...,55,183,184,...,191 for the beginning of the SS / PBCH block.

[0049] - PBCH:

[0050] -- OFDM symbol numbers l=1,3 for the beginning of the SS / PBCH block, and subcarrier numbers k=0,1,...,239 for the beginning of the SS / PBCH block.

[0051] -- OFDM symbol number l=2 for the beginning of the SS / PBCH block, and subcarrier number k=0,1,...,47,192,193,...,239 for the beginning of the SS / PBCH block.

[0052] - PBCH uses DMRS:

[0053] -- OFDM symbol numbers l=1,3 for the beginning of the SS / PBCH block, and subcarrier numbers k=0+v,4+v,8+v,...,236+v for the beginning of the SS / PBCH block.

[0054] -- OFDM symbol number l=2 for the beginning of the SS / PBCH block, and subcarrier number k=0+v,4+v,8+v,...,44+v,192+v,196+v,...,236+v for the beginning of the SS / PBCH block.

[0055] (SSB diagram: Physical layer procedures for control / Synchronization procedures / Cell search)

[0056] In the existing specification, within a half-frame that accompanies multiple SS / PBCH blocks, the initial (first) symbol index for multiple candidate SS / PBCH blocks is determined according to the SCS of the multiple SS / PBCH blocks, as follows. Here, index 0 represents the first symbol of the first slot within the half-frame.

[0057] - Case A - 15 kHz SCS: The initial symbols of multiple candidate SS / PBCH blocks have indices of {2,8}+14·n.

[0058] -- In operation without shared spectrum channel access

[0059] --- For carrier frequencies below 3 GHz (FR1), n=0,1.

[0060] --- For carrier frequencies within FR1 greater than 3 GHz, n=0,1,2,3.

[0061] -- In the operation of accompanying shared spectrum channel access, n=0,1,2,3,4.

[0062] - Case B - 30 kHz SCS: The initial symbols of multiple candidate SS / PBCH blocks have indices of {4, 8, 16, 20} + 28·n. For carrier frequencies below 3 GHz (FR1), n ​​= 0; for carrier frequencies within FR1 above 3 GHz, n = 0, 1.

[0063] - Case C - 30 kHz SCS: The initial symbols of multiple candidate SS / PBCH blocks have indices of {2,8}+14·n.

[0064] -- In operation without shared spectrum channel access

[0065] --- In paired spectrum operation (FDD), for carrier frequencies below 3 GHz (FR1), n=0,1; for carrier frequencies within FR1 above 3 GHz, n=0,1,2,3. In operation accompanied by shared spectrum channel access, n=0,1,2,3,4.

[0066] --- In unpaired spectrum operation (TDD), for carrier frequencies less than 1.88 GHz (FR1), n=0,1, and for carrier frequencies within FR1 above 1.88 GHz, n=0,1,2,3.

[0067] -- In the operation of accompanying shared spectrum channel access, n=0,1,2,3,4,5,6,7,8,9.

[0068] - Case D - 120 kHz SCS: The initial symbols of multiple candidate SS / PBCH blocks have indices of {4, 8, 16, 20} + 28·n. For the carrier frequency within FR2, n = 0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0069] - Case E - 240 kHz SCS: The initial symbols of multiple candidate SS / PBCH blocks have indices of {8,12,16,20,32,36,40,44} + 56·n. For the carrier frequency within FR2-1, n = 0,1,2,3,5,6,7,8.

[0070] - Case F - 480 kHz SCS: The initial symbols of multiple candidate SS / PBCH blocks have indices of {2,9} + 14·n. For the carrier frequency within FR2-2, n = 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31.

[0071] - Case G - 960 kHz SCS: The initial symbols of multiple candidate SS / PBCH blocks have indices of {2,9} + 14·n. For the carrier frequency within FR2-2, n = 0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31.

[0072] In the above scenarios, where the SCS of the SS / PBCH block is not provided by ssbSubcarrierSpacing, the applicable scenarios for a particular cell depend on the corresponding frequency band.

[0073] (Reusable patterns for SSB and CORESET#0)

[0074] In the existing specifications, the multiplexing patterns of SSB and CORESET#0 for FR and {SSB SCS, CORESET#0 SCS} are defined as follows.

[0075] - FR1: For {15, 15} kHz, {30, 30} kHz, {15, 30} kHz, {30, 15} kHz, apply multiplexing pattern 1 ( Figure 1A ).

[0076] - FR2-1:

[0077] -- For {120, 60} kHz and {240, 120} kHz, apply multiplexing pattern 1 and multiplexing pattern 2 ( Figure 1B ).

[0078] -- For {120, 120} kHz, apply multiplexing pattern 1 and multiplexing pattern 3 ( Figure 1C ).

[0079] -- For {240, 60} kHz, apply multiplexing pattern 1.

[0080] - FR2-2:

[0081] -- For {120, 120} kHz, {480, 480} kHz, and {960, 960} kHz, apply multiplexing pattern 1 and multiplexing pattern 3.

[0082] For the minimum channel bandwidth, the SCS of the SS / PBCH block, and the SCS of the PDCCH, a set of multiple resource blocks and multiple symbols for the CORESET of type 0-PDCCH CSS set is defined. Figure 2 Table P-1 is shown, which represents the set of multiple resource blocks and symbols of the CORESET used in the case of {SS / PBCH block SCS, PDCCH SCS} being {15, 15} kHz in a frequency band with a minimum channel bandwidth of 5 MHz or 10 MHz. The index of this table is provided by the MIB (controlResourceSetZero within pdcch-ConfigSIB1). For the index value, the multiplexing pattern of the SS / PBCH block and CORESET, the number of RBs of the CORESET, the number of symbols of the CORESET, and the RB offset of the CORESET are defined.

[0083] (Monitoring of CORESET#0 PDCCH: Physical layer procedures for control / UE procedure for monitoring Type0-PDCCH CSS sets)

[0084] In the existing specifications, the parameters used for monitoring CORESET#0 PDCCH are determined according to a table.

[0085] For FR and multiplexed patterns, parameters are defined for the timing of PDCCH monitoring of the CSS collection of type 0-PDCCH. Figure 3 Table P-11 is shown, which represents the parameters for PDCCH monitoring timings used for the Type 0-PDCCH CSS set of FR1 and multiplexing pattern 1. The index of this table is provided by the MIB (searchSpaceZero within pdcch-ConfigSIB1). For the index values, O, the number of search space sets per slot, M, and the initial symbol index of the PDCCH monitoring timing are defined.

[0086] In operation without shared spectrum channel access (listen before talk (LBT)) (licensed band) and in multiplexing pattern 1 of SS / PBCH blocks and CORESET, the UE monitors the PDCCH within a type 0-PDCCH CSS set spanning two slots. For an SS / PBCH block with index i, the UE determines the index of slot n0 as n0 = (0.2). μ +ceil(i·M)) mod N slot frame,μ This time slot n0 is located in the system frame number SFN. c Within the frame, where ceil(O·2) μ +ceil(i·M)) / N slot frame,μ When mod 2=0, the system frame number SFN c Satisfy SFN c mod 2=0, or the time slot n0 is located in the system frame number SFN. c Within the frame, where ceil(O·2) μ +ceil(i·M)) / N slot frame,μ When mod 2=1, the system frame number SFN c Satisfy SFN c mod 2 = 1. Here, based on the SCS used for PDCCH reception within this CORESET, μ ∈ {0, 1, 2, 3, 5, 6}. The two time slots follow the following.

[0087] - For an SS / PBCH block with μ∈{0,1,2,3} and index i, the two slots containing the associated type 0-PDCCH monitoring timing are slots n0 and n0+1. The indices of the initial symbols of M, O, and CORESET within slots n0 and n0+1 are given by the corresponding table in the specification.

[0088] - For SS / PBCH blocks with μ=5 and index i, the two slots containing the associated type 0-PDCCH monitoring timing are slots n0 and n0+4. The indices of the initial symbols of M, O, and CORESET within slots n0 and n0+4 are given by the corresponding table in the specification. Here, X=1.25.

[0089] - For SS / PBCH blocks with μ=6 and index i, the two slots containing the associated type 0-PDCCH monitoring timing are slots n0 and n0+8. The indices of the initial symbols of M, O, and CORESET within slots n0 and n0+8 are given by the corresponding table in the specification. Here, X=0.625.

[0090] In the operation accompanying shared spectrum channel access (unlicensed band) and multiplexing pattern 1 of SS / PBCH blocks and CORESET, the UE monitors the PDCCH within a Type 0-PDCCH CSS set spanning multiple time slots. Where the characteristics of 'type A' and 'type D' of average gain, quasi co-location (QCL) are applicable, with respect to these characteristics, the multiple time slots contain Type 0-PDCCH monitoring opportunities associated with SS / PBCH blocks that perform QCL with the CORESET providing the Type 0-PDCCH CSS set. For 0≤i - ≤L max - -1. Candidate SS / PBCH block index i - The two time slots contain the associated Type 0-PDCCH monitoring opportunities. The UE determines the index of time slot n0 as n0 = (0.2 μ +ceil(i - ·M)) mod N slot frame,μ This time slot n0 is located in the system frame number SFN. c Within the frame, where ceil(O·2) μ +ceil(i - ·M)) / N slot frame,μ When mod 2=0, the system frame number SFN c Satisfy SFN c mod 2=0, or the time slot n0 is located in the system frame number SFN. c Within the frame, where ceil(O·2) μ +ceil(i - ·M)) / N slot frame,μ When mod 2=1, the system frame number SFN c Satisfy SFN c mod 2 = 1. Here, based on the SCS used for PDCCH reception within this CORESET, μ ∈ {0, 1, 3, 5, 6}. The two time slots follow the following.

[0091] - For μ∈{0,1} and having index i - The SS / PBCH block, containing the associated type 0-PDCCH monitoring timing in the two slots n0 and n0+1, the indices of the initial symbols of M, O, and CORESET within slots n0 and n0+1 are given through the corresponding table in the specification. The UE in N SSB QCL When M=1, it is not expected to be set to M=1 / 2 or M=2.

[0092] - For μ=3 and with index i - The SS / PBCH block, which includes the associated type 0-PDCCH monitoring timing, has two slots, slots n0 and n0+1, M, O, and the index of the initial symbol of the CORESET within slots n0 and n0+4, given by the corresponding table in the specification.

[0093] - For μ=5 and with index i - The SS / PBCH block, containing the associated type 0-PDCCH monitoring timing in the two slots n0 and n0+4, the indices of the initial symbols of M, O, and CORESET within slots n0 and n0+4 are given by the corresponding table in the specification. Here, X=1.25.

[0094] - For μ=6 and with index i - The SS / PBCH block, containing the associated type 0-PDCCH monitoring timing in the two slots n0 and n0+8, the indices of the initial symbols of M, O, and CORESET within slots n0 and n0+8 are given by the corresponding table in the specification. Here, X=0.625.

[0095] (analyze)

[0096] SCS frequencies above 960kHz are being investigated. However, designs using SCS frequencies above 960kHz have not been adequately studied. Furthermore, the monitoring operation of the PDCCH scheduling SIB1 during initial DL access using SCS frequencies above 960kHz has not been adequately studied. If such designs / operations are not adequately studied, there are concerns about reduced communication quality / throughput.

[0097] Therefore, the inventors of this invention conceived of designing / operating a signal using an SCS greater than 960 kHz.

[0123] (Wireless communication method)

[0124] <Implementation Method 1>

[0125] This implementation relates to the SCS of the SSB.

[0126] For SSB, new SCS (specific SCS) are supported for frequencies greater than 960kHz.

[0127] SSB SCS (specific SCS) greater than 960 kHz can also be applied under specific conditions.

[0128] In this disclosure, a specific condition may also include at least one of a specific FR, a specific band domain, and a specific scenario. A specific band domain may also include at least one of a band domain exceeding 71 GHz, an Asia-Pacific Hertz band domain, and a terahertz band domain. A specific scenario may also include at least one of a terrestrial network (TN), a non-terrestrial network (NTN), TDD, FDD, a licensed band domain, and an unlicensed band domain.

[0129] The determination of SSB SCS under specific conditions may also follow at least one of the following options.

[0130] - Option 1: SSB SCS is provided by the higher-level parameter ssbSubcarrierSpacing. New candidate values ​​for the higher-level parameter ssbSubcarrierSpacing can also be supported / imported for specific conditions. The SSB in this option can also be a measurement SSB.

[0131] - Option 2: Define SSB SCS based on specific conditions. The specification can also define the SCS of SSBs under specific conditions.

[0132] Option 3: The UE performs blind detection of the SSB SCS based on applicable conditions. Applicable conditions can also be determined based on specific conditions. The specification can also define a set of applicable values ​​for the SSB SCS under specific conditions. The UE can also use the set of applicable values ​​and the corresponding SSB patterns to perform blind detection of the SSB.

[0133] - Option 4: The SSB SCS is set / indicated by settings / indications on other cells. These other cells can also be cells in a lower frequency band. The SSB SCS on a cell under specific conditions can also be determined based on parameters from another cell in a lower frequency band.

[0134] Option 5: The UE performs blind detection of SSB SCS based on applicable conditions. Applicable conditions are set / indicated through settings / indications on other cells. Other cells can also be cells in lower frequency bands. The set of applicable values ​​for a cell's SSB SCS can also be indicated through parameters on other cells. The UE can also perform blind detection of SSB using the set of applicable values ​​and the corresponding SSB pattern.

[0135] According to this implementation, the UE can appropriately determine the SCS of the SSB. When SCS above 960kHz is supported in the SSB and other signals / channels, implementation can be simplified by supporting operation with a single parameter set.

[0136] <Implementation Method 2>

[0137] This implementation involves the design of SSB patterns.

[0139] The number of SSB limits for a specific SCS greater than 960 kHz can also be defined.

[0140] The maximum number of SSB indices within a cell can also be greater than 64. This maximum number could be, for example, 96 / 128 / 160 / 192, etc. This maximum number can also depend on the SCS and specific conditions, as defined in the specification.

[0141] The maximum number of SSBs that can be sent within a specific time period can also be greater than 64. This maximum number could be, for example, 96 / 128 / 160 / 192, etc. This maximum number can also depend on at least one of a specific SCS and specific conditions, as defined in the specification.

A specific time can be one half-frame, X frames / half-frames / subframes / time slots, or X milliseconds / seconds / minutes / hours, etc. A specific time can also depend on specific conditions. The maximum number of SSBs transmitted within a specific time can also be greater than 64. For example, in FRs above 72 GHz, the maximum number of SSBs transmitted within a frame can also be greater than 64.

Since the time of each candidate SSB is 4 symbols, the symbol indices of the time position range of the candidate SSBs are {2, 3, 4, 5, 9, 10, 11, 12, ...}.

[0257] The SSB symbol positions for a specific SCS are determined using the same principles as the SSB pattern design in cases A / F / G. Alternatively, the SSB symbol positions for a specific SCS may be the same in each time slot as in cases A / F / G. For a specific SCS, one or two SSBs may also be configured / transmitted per time slot.

[0258] This option may also follow at least one of the following examples 2-x.

[0259] -- Example 2-1: An SSB is configured / transmitted within a time slot. This example may also have at least one of the following characteristics.

[0260] --- Multiple time slots containing an SSB can be consecutive or non-consecutive.

[0261] --- The initial code of a candidate SSB can also have {x}+14 The index of n. As in implementation method 2-2, n can also be the index of a time slot that includes an SSB.

[0262] --- The value of x can also represent the initial symbol index of the SSB within each SSB slot. The initial symbol index of the SSBs within each SSB slot can also be the same. The value of x can also be 0 / 1 / 2 / 3 / 4 / 5 / 6 / 7 / 8 / 9 / 10. The value of x can be defined by the specification or indicated by the MIB.

[0263] -- Example 2-2: Two SSBs are configured / transmitted within one time slot. This example may also have at least one of the following characteristics.

[0264] --- Multiple time slots containing an SSB can be consecutive or non-consecutive.

[0265] --- The initial code of a candidate SSB can also have {x, x+4+y}+14 The index of n. As in implementation method 2-2, n can also be the index of a time slot that includes an SSB.

[0266] The value of x can also represent the initial symbol index of the first SSB within each SSB slot. The initial symbol index of the first SSB within each SSB slot can also be the same. The value of x can also be 0 / 1 / 2 / 3 / 4 / 5 / 6. The value of x can be defined by the specification or indicated by the MIB.

[0267] --- The value of y can also represent the gap between two SSBs within each SSB time slot. The value of y can also be 0 / 1 / 2 / 3 / 4 / 5 / 6. The value of y can be defined by the specification or indicated by the MIB. The value of y can also depend on at least one of the SSB SCS (specific SCS) and specific conditions.

[0268] --- x+y<7

[0269] -- Variation of Example 2-2: Two SSBs are configured / sent within a time slot. These two SSBs can have the same SSB index or different SSB indices. Whether the two SSBs have the same or different SSB indices can also depend on the interval between the two SSBs within a time slot. For example, if y is less than a certain value, the two SSBs have the same SSB index; otherwise, the two SSBs have different SSB indices.

[0270] In each example, index 0 may also correspond to the first symbol of the first slot within a specific time period.

[0271] Figure 8 This is an example of the SSB pattern in Example 2-1. In specific SCSs of 1920kHz and 3840kHz, the initial symbol index of the candidate SSB for the initial symbol of each time slot is {2}, and the initial symbol index of the candidate SSB for the initial symbol of the initial time slot within a specific time period is {2, 9, 16, 23, 30, 37, 44, 51, ...}. The time of each candidate SSB can also be the four symbols of a specific SCS.

[0272] Figure 9This is an example of the SSB pattern in Example 2-2. In specific SCSs of 1920kHz and 3840kHz, the initial symbol index of the candidate SSB for the first symbol in each time slot is {2,9}, and the initial symbol index of the candidate SSB for the first symbol in the first time slot within a specific time period is {2,9,16,23,30,37,44,51,...}. The time of each candidate SSB can also be the four symbols of a specific SCS.

[0273] - Option 3

[0274] The number of gap symbols between any two adjacent (indexed consecutive) SSBs can be the same. Even if the two SSBs are located in different time slots, the number of gap symbols between the two SSBs can be the same.

[0275] The gap can also be to ensure that the UE has enough time to switch the SSB receive beam for different SSB indices.

[0276] For different SCSs, the absolute length of the gap between two adjacent SSBs can also be the same.

[0277] The gap can also be the interval between the end symbol of the first SSB and the start symbol of the second SSB in two adjacent SSBs.

[0278] The length of the gap can also be y symbols per slot. The value of y can be defined by the specification or indicated by the MIB. The unit of y (symbol or slot) can be defined by the specification or indicated by the MIB.

[0279] The length of the gap can also depend on at least one of the SSB, SCS (specific SCS), and specific conditions.

[0280] The length of the gap can also be scaled based on the length of the gap between multiple SSBs in the reference SCS (reference gap length). For example, if the reference SCS is 960kHz, and the length of the gap in a specific SCS is based on the reference gap length of 3 symbols between multiple SSBs in the reference SCS, then the length of the gap in the 1920kHz SCS is 6 symbols, the length of the gap in the 3820kHz SCS is 12 symbols, and the length of the gap in the 7680kHz SCS is 24 symbols.

[0281] When the length scaled based on the reference gap length is longer than one time slot, the length of the gap in a specific SCS can also be determined in units of time slots. The length of the gap in a specific SCS can also be given by the minimum number of time slots that is greater than the length scaled based on the reference gap length. For example, if the reference SCS is 960 kHz, and the length of the gap in a specific SCS is based on the reference gap length of 3 symbols between multiple SSBs in the reference SCS, then since the length scaled for the 7680 kHz SCS is 24 symbols, the length of the gap is 2 time slots.

[0282] This option may also follow at least one of the following examples 3-x.

[0283] -- Example 3-1: The gap is in units of symbols. The initial symbol of a candidate SSB can also have {x + (4 + y)}. The index of n}. n can be the index of the SSB, or n = 0, 1, 2, 3, ..., L max -1. The value of x can also represent the initial symbol index of the initial SSB within a specific time period. The value of x can be defined by the specification or indicated by the MIB. The value of y can also represent the length of the gap between two SSBs. The length of this gap can also be determined according to option 3-1.

[0284] -- Example 3-2: The gap is in units of time slots. The initial symbol of a candidate SSB can also have {x+14}. y The index of n}. n can be the index of the SSB, or n = 0, 1, 2, 3, ..., L max -1. The value of x can also represent the initial symbol index of the initial SSB within a specific time period. The value of x can be defined by the specification or indicated by the MIB. The value of y can also represent the length of the gap between two SSBs. The length of this gap can also be determined according to option 3-1.

[0285] In each example, index 0 may also correspond to the first symbol of the first slot within a specific time period.

[0286] Figure 10 This is an example of the SSB pattern in Example 3-1. In specific SCSs of 1920 kHz and 3840 kHz, the initial symbol index of the first SSB within a specific time period is 2. The reference SCS is 960 kHz, and the reference gap length is 3 symbols. The length of the gap in a specific SCS is obtained by scaling the reference gap length using the specific SCS. The gap in a specific SCS of 1920 kHz is 6 symbols. The gap in a specific SCS of 3840 kHz is 12 symbols.

[0287] Figure 11 This illustrates an example of the SSB pattern in Example 3-2. In a specific SCS = 7680 kHz, the initial symbol index of the first SSB within a specific time period is 2. The reference SCS is 960 kHz, the reference gap length is 3 symbols, and the gap length in the specific SCS is obtained by scaling the reference gap length using the specific SCS and rounding up in time slot units. In the specific SCS = 7680 kHz, the scaled length is 24 symbols, and the gap in time slot units is 2 time slots.

[0288] - Changes to option 3

[0289] All SSB indices can also be divided into K groups (SSB groups). As described in option 4 below, multiple SSBs within a group can also have equal-length gaps. The symbol positions of the SSBs can also be the same in different groups. In other words, the SSB pattern can repeat in all groups.

[0290] Alternatively, imagine K SSB groups, where each SSB group contains N SSBs. Regarding the initial symbol indices of the N SSBs within the first group, option 3 (L) can also be used. max Replace with N, based on option 3. The initial symbol index of the SSBs within the remaining groups can also be determined based on the SSB group index and the slot offset between the SSB groups. For example, when the offset between two adjacent SSB groups is m slots, the initial symbol index of multiple SSBs within the (k+1)th SSB group can also be determined by "symbol index within the first SSB group" + k. m The value is determined by 14 (k=1,2,...,K-1). K can also be the SSB group index {0,1,2,...,K-1}. The offset between two adjacent SSB groups is m time slots, or it can be that in the two SSBs, the index of the initial time slot of the first SSB group is i, and the index of the initial time slot of the second SSB group is i+m.

[0291] Figure 12 This illustrates an example of the SSB pattern for option 3 in implementation method 2-3. The initial symbol indices of the four SSBs in the first SSB group (SSB group index 0) are {i0, i1, i2, i3}. The initial symbol indices of the four SSBs in the (k+1)th SSB group (SSB group index k) are {i0+k}. m 14, i1+k m 14, i2+k m 14, i3+k m 14}.

[0292] <<<Changes in Implementation Methods 2-3>>>

[0293] In implementation methods 2-3, the choice of which option to apply can also depend on a specific SCS. Different options can also be applied depending on the specific SCS.

[0294] Option 1-1 / Option 1-2 can also be combined with Option 2 / 3. This combination can also follow the examples below.

[0295] - Example: Option 2 / 3 can also be applied to the determination / design of SSB position / pattern for an object SCS (e.g., an SCS greater than 960kHz). Option 1-1 / 1-2 can also be applied to the determination / design of SSB position / pattern for an SCS other than the object (e.g., another SCS greater than 960kHz). In option 1-1 / 1-2, the object SCS can also be used as a reference SCS. For example, it is also possible that the SSB pattern for a 1920kHz SCS is determined by option 2 / 3, and the SSB pattern for a 3840kHz SCS is determined by using option 1-1 / 1-2, which uses a 1920kHz SCS as the reference SCS.

[0296] According to this implementation, the UE can appropriately determine the pattern / position of the SSB in a specific SCS.

[0297] <Implementation Method 3>

[0298] This implementation involves monitoring CORESET#0.

[0299] <<Implementation Method 3-1>>

[0300] A UE operating under specific conditions may also determine the SCS of CORESET#0 (the SCS of PDCCH). The SCS of CORESET#0 may also follow at least one of the following options.

[0301] - Option a: The SCS of CORESET#0 is the same as the SCS of SSB.

[0302] - Option b: The SCS of CORESET#0 is set / indicated by the base station. For example, the SCS of CORESET#0 is set / indicated by the subCarrierSpacingCommon within the MIB.

[0303] Options can also depend on specific conditions. Different options can be supported / applied for different specific conditions.

[0304] <<Implementation Method 3-2>>

[0305] The relationship between the SCS of the SSB (SSB SCS, first SCS) and the SCS of the PDCCH (CORESET#0) (PDCCH SCS, CORESET#0 PDCCH SCS, second SCS) can also be defined. Alternatively, the SSB SCS can be x1 kHz, and the PDCCH SCS can be x2 kHz.

[0306] In this disclosure, the combinations of SSB SCS and PDCCH SCS, SCS combinations, {SSB, PDCCH}SCS, {X1, X2} [kHz], and SCS combination types can also be rewritten to each other.

[0307] SCS combinations can also follow at least one of the following SCS combination types.

[0330] <<<Changes to Implementation Method 3-2>>>

[0331] At least one SCS combination type from 1 to 3 may be supported or not. For example, SCS combination type 1 may not be supported, but SCS combination types 2 / 3 may be supported. For example, SCS combination type 1 may be supported, but SCS combination types 2 / 3 may not be supported.

[0332] At least one of X1 and X2 can be made from 15.2 μ The value represented may not be 15.2 μ The value represented.

[0333] <<Implementation Method 3-3>>

[0334] You can also define a multiplexing pattern between SSB and CORESET#0.

[0335] For SCS combination types 1 / 2 / 3, it is also possible to support at least one of the following: a pattern in which SSB and CORESET#0 are TDM (multiplexed pattern 1), a pattern in which SSB and CORESET#0 are FDM (multiplexed pattern 3), and a pattern in which SSB and CORESET#0 are both TDM and FDM (multiplexed pattern 2).

[0336] In the reused pattern 1, as described above Figure 1A Therefore, the frequency resources (bandwidth) of the SSB can be different from or the same as the frequency resources (bandwidth) of the CORESET / PDSCH. In multiplexing pattern 2, as described above... Figure 1B Therefore, the frequency resources (bandwidth) of the SSB and the PDSCH can be the same or different. In multiplexing pattern 2, as described above... Figure 1B Therefore, the time resources (number of symbols) of CORESET and PDSCH can be the same or different.

In multiplexing pattern 3, as described above... Figure 1C In that case, the time resources (number of symbols) of SSB and PDSCH can be the same as or different from the time resources (number of symbols) of CORESET.

[0337] <<<Changes to Implementation Method 3-3>>>

[0338] The multiplexing pattern can also depend on at least one parameter among SSB SCS, PDCCH SCS, SCS combination type, the relationship between SSB SCS and PDCCH SCS, and specific conditions. Different values ​​of this parameter can result in different applicable multiplexing patterns. Different values ​​of this parameter can also support different multiplexing patterns. This implementation can also follow at least one of the following examples.

[0339] Example 1: The multiplexing pattern supported for SCS combination type 1 is pattern 1 / 3.

[0340] Example 2: The multiplexing pattern supported for SCS combination type 2 is pattern 1 / 2.

[0341] Example 3: The multiplexing pattern supported for SCS combination type 3 is pattern 1.

[0342] <<Implementation Methods 3-4>>

[0343] A method for determining the timing of PDCCH monitoring can also be defined for at least one of the SSB SCS and PDCCH SCS that is greater than 960kHz, using CORESET#0 (for type 0-PDCCH CSS set).

[0344] The monitoring slot of CORESET#0 PDCCH can also follow at least one of the following procedures 1-x.

[0345] - Procedure 1-1: The UE monitors the PDCCH within the Type 0-PDCCH CSS set spanning X time slots. The X time slots could also be, for example, time slot #n0, time slot #(n0+N), time slot #(n0+2), etc. N), ... time slot # (n0 + (X-1) N). The values ​​of X and N can also follow the following.

[0346] -- The value of X can be defined by the specification or indicated by the MIB. The value of X can also be the same for multiple different values ​​of at least one parameter in SCS combination type, multiplexing pattern, SSBSCS, PDCCH SCS.

[0347] -- The value of N can be defined by the specification or indicated by the MIB. The value of N can also be the same for multiple different values ​​of at least one parameter in SCS combination type, multiplexing pattern, SSBSCS, PDCCH SCS.

[0348] - Process 1-2: The value of n0 can also follow at least one of the following options.

[0349] -- The value of option a:n0 is determined based on the CORESET#0 monitoring parameter indicated by MIB.

[0350] -- Option b: The value of n0 is determined based on the time slot of the corresponding SSB. For example, it can be n0 = n_SSB, n0 = n_SSB - n_offset, or n0 = n_SSB + n_offset. Here, n_SSB is the time slot index of the received SSB, and n_offset can be defined by the specification or indicated by the MIB.

[0351] -- Variation: The choice between option a and option b can also be based on the multiplexing pattern. Different options can also be applied for different multiplexing patterns. For example, option a can be applied for multiplexing pattern 1, and option b can be applied for multiplexing pattern 3 / 2.

[0352] The length of CORESET#0 PDCCH can also follow the following process 2.

[0353] - Procedure 2: The number of symbols in CORESET#0 PDCCH can be any one of 1, 2, 3, 4, ... The number of symbols in CORESET#0 PDCCH can be defined by the specification or indicated by the MIB.

[0354] - Variation: The length of CORESET#0 PDCCH can also depend on at least one parameter in the combination of multiplexing pattern, SSB SCS, PDCCH SCS, and SCS. Different values ​​of this parameter can also result in different values ​​for the length of CORESET#0 PDCCH. For example, the length of CORESET#0 PDCCH for multiplexing pattern 1 can be 1 / 2 / 3 symbols. For example, the length of CORESET#0 PDCCH for multiplexing pattern 3 can be 1 symbol. For example, the length of CORESET#0 PDCCH for multiplexing pattern 2 can also be 1 symbol.

[0355] The initial symbol index for the CORESET#0 PDCCH monitoring timing can also follow the following process 3.

[0356] - Procedure 3: The initial symbol index for a Type 0-PDCCH monitoring event within multiple monitoring slots can be defined by the specification or indicated by the MIB. If the initial symbol index is defined by the specification, the rules for this initial symbol index can also be based on the symbols of the corresponding SSB. For example, the start / end symbols of a Type 0-PDCCH monitoring event are aligned with the start or end symbols of the corresponding SSB. For example, the start or end symbols of a Type 0-PDCCH monitoring event are X symbols before or X symbols after the start or end symbols of the corresponding SSB.

[0357] The frequency domain resources of CORESET#0 can also follow the process 4-x below.

[0358] - Procedure 4-1: The number of RBs for CORESET#0 can also be 4 / 8 / 12 / 16 / 24 / 48 / 96 / 192 / 384, etc. The number of RBs for CORESET#0 can be defined by the specification or indicated by the MIB.

[0359] - Procedure 4-2: The RB offset of CORESET#0 can also be 0 / 1 / 2 / 3 / 4 / 8 / 9, etc. The RB offset of CORESET#0 can be defined by the specification or indicated by the MIB.

[0360] - Variation: The number of RBs for CORESET#0 can also depend on at least one parameter among the multiplexing pattern, SSB SCS, PDCCH SCS, and SCS combinations. Different values ​​for this parameter can also result in different values ​​for the number of RBs for CORESET#0. For example, 24 / 48 / 96 can be used for the number of RBs for CORESET#0 of multiplexing pattern 1. For example, 24 / 48 can be used for the number of RBs for CORESET#0 of multiplexing pattern 3 / 2.

[0361] According to this implementation, the UE can properly monitor CORESET#0.

[0362] <Cases of Mandatory Functions>

[0363] At least one function in the above embodiments can also be a mandatory function of the UE in a specific radio communication system (RAT). The UE can be set / instructed to perform the function without reporting the UE capabilities associated with the function, or the UE can perform the function (mandatory without capability signaling). The UE can also be set to require reporting the UE capabilities associated with the function (mandatory with capability signaling).

[0446] (Wireless communication system)

[0447] The structure of a wireless communication system according to one embodiment of this disclosure will now be described. In this wireless communication system, communication is performed using any one or a combination of the wireless communication methods according to the above embodiments of this disclosure.

[0448] Figure 13 This is a diagram illustrating an example of the schematic structure of a wireless communication system according to one embodiment. The wireless communication system 1 (also referred to simply as System 1) may also be a system that uses Long Term Evolution (LTE) or 5th generation mobile communication system New Radio (5G NR) as standardized by the Third Generation Partnership Project (3GPP) to achieve communication.

[0449] Furthermore, the wireless communication system 1 can also support dual connectivity between multiple radio access technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC can also include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA)) and NR (E-UTRA-NR Dual Connectivity (EN-DC)), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NE-DC)), etc.

[0450] In EN-DC, the LTE (E-UTRA) base station (eNB) is the Master Node (MN), and the NR base station (gNB) is the Secondary Node (SN). In NE-DC, the NR base station (gNB) is the MN, and the LTE (E-UTRA) base station (eNB) is the SN.

[0451] Wireless communication system 1 can also support dual connectivity between multiple base stations within the same RAT (e.g., MN and SN are dual connectivity between NR base stations (gNB) (NR-NR Dual Connectivity (NN-DC))).

[0452] The wireless communication system 1 may also include a base station 11 forming a macro cell C1 with a relatively wide coverage area, and a base station 12 (12a-12c) configured within the macro cell C1 and forming a small cell C2 narrower than the macro cell C1. The user terminal 20 may also be located within at least one cell. The configuration and number of each cell and the user terminal 20 are not limited to the arrangement shown in the figure. Hereinafter, without distinguishing between base stations 11 and 12, they will be collectively referred to as base station 10.

[0453] User terminal 20 may also connect to at least one of multiple base stations 10. User terminal 20 may also utilize at least one of carrier aggregation (CA) using multiple component carriers (CC) and dual connectivity (DC).

[0454] Each CC can also be included in at least one of the first frequency band (Frequency Range 1 (FR1)) and the second frequency band (Frequency Range 2 (FR2)). Macro cell C1 can also be included in FR1, and small cell C2 can also be included in FR2. For example, FR1 can also be a frequency band below 6 GHz (sub-6 GHz), and FR2 can also be a frequency band above 24 GHz (above-24 GHz). In addition, the frequency bands, definitions, etc. of FR1 and FR2 are not limited to these; for example, FR1 can also be equivalent to a frequency band higher than FR2.

[0455] In addition, user terminal 20 can also use at least one of Time Division Duplex (TDD) and Frequency Division Duplex (FDD) to communicate in each CC.

[0456] Multiple base stations 10 can also be connected via wired (e.g., fiber optic cable based on the Common Public Radio Interface (CPRI), X2 interface, etc.) or wireless (e.g., NR communication). For example, when NR communication is used as a backhaul between base stations 11 and 12, base station 11, which is equivalent to a host station, can also be referred to as an Integrated Access Backhaul (IAB) donor, and base station 12, which is equivalent to a relay station, can also be referred to as an IAB node.

[0457] Base station 10 may also be connected to core network 30 via other base stations 10 or directly. Core network 30 may include, for example, at least one of Evolved Packet Core (EPC), 5G Core Network (5GCN), Next Generation Core (NGC), etc.

[0458] The core network 30 may also include, for example, user plane functions (UPF), access and mobility management functions (AMF), session management functions (SMF), unified data management (UDM), application functions (AF), data network (DN), location management functions (LMF), and network functions (NF) such as operation, administration and maintenance (OAM). Alternatively, multiple functions can be provided through a single network node. Furthermore, communication with external networks (e.g., the Internet) can also be achieved via the DN.

[0459] User terminal 20 can also be a terminal that supports at least one of the following communication methods: LTE, LTE-A, 5G, etc.

[0460] In wireless communication system 1, wireless access methods based on Orthogonal Frequency Division Multiplexing (OFDM) can also be used. For example, in at least one of the downlink (DL) and uplink (UL) links, Cyclic Prefix OFDM (CP-OFDM), Discrete Fourier Transform Spread OFDM (DFT-s-OFDM), Orthogonal Frequency Division Multiple Access (OFDMA), and Single Carrier Frequency Division Multiple Access (SC-FDMA) can also be used.

[0461] The wireless access method can also be referred to as a waveform. In addition, in the wireless communication system 1, other wireless access methods (e.g., other single-carrier transmission methods, other multi-carrier transmission methods) can also be used in the wireless access methods of UL and DL.

[0462] In the wireless communication system 1, the downlink channel can also be a shared downlink channel (Physical Downlink Shared Channel (PDSCH)), a broadcast channel (Physical Broadcast Channel (PBCH)), or a downlink control channel (Physical Downlink Control Channel (PDCCH)) shared by each user terminal 20.

[0463] In addition, in the wireless communication system 1, the uplink channel can also be the shared uplink channel (Physical Uplink Shared Channel (PUSCH)), the uplink control channel (Physical Uplink Control Channel (PUCCH)), the random access channel (Physical Random Access Channel (PRACH)) shared by each user terminal 20, etc.

[0464] User data, high-level control information, and System Information Blocks (SIBs) are transmitted via the PDSCH. User data and high-level control information can also be transmitted via the PUSCH. In addition, Master Information Blocks (MIBs) can also be transmitted via the PBCH.

[0465] Lower-layer control information can also be transmitted via PDCCH. This lower-layer control information may include, for example, downlink control information (DCI), which includes scheduling information for at least one of PDSCH and PUSCH.

[0466] Additionally, the DCI that schedules PDSCH can also be called DL allocation, DL DCI, etc., and the DCI that schedules PUSCH can also be called UL authorization, UL DCI, etc. Furthermore, PDSCH can be rewritten as DL data, and PUSCH can be rewritten as UL data.

[0467] In PDCCH detection, a Control Resource Set (CORESET) and a search space can also be utilized. A CORESET corresponds to the resources used to search for DCIs. The search space corresponds to the search area and search method for PDCCH candidates. A CORESET can also be associated with one or more search spaces. The UE can also monitor CORESETs associated with a specific search space based on search space settings.

[0468] A search space can also correspond to one or more PDCCH candidates equivalent to one or more aggregation levels. One or more search spaces can also be referred to as a search space set. In addition, the terms "search space", "search space set", "search space setting", "search space set setting", "CORESET", and "CORESET setting" in this disclosure can be rewritten interchangeably.

[0469] The PUCCH can also transmit uplink control information (uplink control information (UCI)) that includes at least one of the following: Channel State Information (CSI), delivery confirmation information (e.g., also known as Hybrid Automatic Repeat Request ACK Knowledge (HARQ-ACK), ACK / NACK, etc.), and Scheduling Request (SR). The PRACH can also transmit random access preambles used for establishing connections with the cell.

[0470] In addition, in this disclosure, downlink, uplink, etc., may be described without the word "link". Furthermore, various channels may be described without the word "physical".

[0471] In wireless communication system 1, synchronization signals (SS) and downlink reference signals (DL-RS) can also be transmitted. In wireless communication system 1, DL-RS can also transmit cell-specific reference signals (CRS), channel state information reference signals (CSI-RS), demodulation reference signals (DMRS), positioning reference signals (PRS), and phase tracking reference signals (PTRS).

[0472] Synchronization signals can be, for example, at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). A signal block containing SS (PSS, SSS) and PBCH (and DMRS for PBCH) can also be called an SS / PBCH block, SS block (SSB), etc. In addition, SS, SSB, etc. can also be called reference signals.

[0473] Furthermore, in wireless communication system 1, the uplink reference signal (UL-RS) can also transmit measurement reference signals (sounding reference signals (SRS)) and demodulation reference signals (DMRS). Additionally, DMRS can also be referred to as user terminal-specific reference signals (UE-specific reference signals).

[0494] (User terminal)

[0495] Figure 15This diagram illustrates an example of the structure of a user terminal according to one embodiment. The user terminal 20 includes a control unit 210, a transmitting / receiving unit 220, and a transmitting / receiving antenna 230. Alternatively, more than one of each of the control unit 210, the transmitting / receiving unit 220, and the transmitting / receiving antenna 230 may be included.

[0496] Furthermore, while this example primarily illustrates the functional blocks of the characteristic portions of this embodiment, it is also conceivable that the user terminal 20 may also have other functional blocks required for wireless communication. Some of the processing of each unit described below may also be omitted.

[0497] The control unit 210 performs overall control of the user terminal 20. The control unit 210 can be composed of a controller, control circuit, etc., which are described based on common knowledge in the technical field to which this disclosure pertains.

[0498] The control unit 210 can also control signal generation, mapping, etc. The control unit 210 can also control transmission, reception, measurement, etc., using the transmission / reception unit 220 and the transmission / reception antenna 230.

[0500] The transmitting and receiving unit 220 can be configured as a single integrated transmitting and receiving unit, or it can be composed of a transmitting unit and a receiving unit. The transmitting unit can also be composed of a transmitting processing unit 2211 and an RF unit 222. The receiving unit can also be composed of a receiving processing unit 2212, an RF unit 222, and a measurement unit 223.

[0503] The transmitting and receiving unit 220 may also use digital beamforming (e.g., precoding), analog beamforming (e.g., phase rotation), etc., to form at least one of the transmitting beam and the receiving beam.

[0504] The transmitting and receiving unit 220 (transmitting processing unit 2211) may, for example, perform PDCP layer processing, RLC layer processing (e.g., RLC retransmission control), MAC layer processing (e.g., HARQ retransmission control) on the data and control information obtained from the control unit 210, and generate the bit string to be transmitted.

For example, the measurement unit 223 can also perform RRM measurements, CSI measurements, etc., based on the received signal. The measurement unit 223 can also measure received power (e.g., RSRP), received quality (e.g., RSRQ, SINR, SNR), signal strength (e.g., RSSI), propagation path information (e.g., CSI), etc. The measurement results can also be output to the control unit 210.

Furthermore, the measurement unit 223 can also derive interference measurements for CSI calculation based on interference measurement resources. Interference measurement resources can be at least one of NZP CSI-RS resources for interference measurement, CSI-Interference Measurement (IM) resources, etc. Additionally, CSI-IM can also be referred to as CSI-Interference Management (IM), and can be interchanged with zero power (ZP) CSI-RS.

[0517] The transmitting / receiving unit 220 can also receive a synchronization signal block having a first subcarrier spacing (SCS). The control unit 210 can also determine a second SCS of the control resource set based on specific conditions and the synchronization signal block. At least one of the first SCS and the second SCS can also be higher than 960 kHz.

[0518] The specific conditions can also represent the relationship between the first SCS and the second SCS.

[0519] The control unit 210 can also determine the multiplexing pattern between the synchronization signal block and the control resource set based on the specific conditions.

[0520] The control unit 210 can also determine the timing of monitoring the physical downlink control channel within the control resource set based on the specific conditions.

[0521] (Hardware structure)

[0522] Furthermore, the block diagrams used in the description of the above embodiments illustrate functional units. These functional blocks (structural units) are implemented through any combination of at least one of hardware and software. Moreover, the implementation method of each functional block is not particularly limited. That is, each functional block can be implemented using a single device that is physically or logically combined, or it can be implemented by directly or indirectly (e.g., using wired, wireless, etc.) connecting two or more physically or logically separate devices. A functional block can also be implemented by combining the aforementioned single device or multiple devices with software.

[0523] Here, the functions include judgment, decision, determination, calculation, calculation, processing, export, investigation, search, confirmation, receiving, sending, output, access, resolution, selection, selection, establishment, comparison, assumption, expectation, regard as, broadcasting, notifying, communicating, forwarding, configuring, reconfiguring, allocating, mapping, and assigning, but are not limited to these. For example, a functional block (structural unit) that implements the sending function can also be called a transmitting unit, transmitter, etc. Each of these, as described above, is not particularly limited in its implementation method.

[0524] For example, in one embodiment of this disclosure, the base station, user terminal, etc., can also function as a computer for processing the wireless communication method of this disclosure. Figure 16 This is a diagram illustrating an example of the hardware structure of a base station and a user terminal according to one embodiment. The base station 10 and the user terminal 20 described above can also be physically configured as a computer device including a processor 1001, a memory 1002, a storage device 1003, a communication device 1004, an input device 1005, an output device 1006, a bus 1007, etc.

The hardware structure of base station 10 and user terminal 20 can be configured to include one or more of the apparatuses shown in the figures, or it can be configured not to include any of the apparatuses.

[0526] For example, only one processor 1001 is shown, but there can be multiple processors. Furthermore, processing can be performed by one processor, or simultaneously, sequentially, or by two or more processors using other methods. Additionally, processor 1001 can be implemented using more than one chip.

[0527] The functions of the base station 10 and the user terminal 20 are implemented, for example, by reading specific software (programs) into hardware such as the processor 1001 and the memory 1002, so that the processor 1001 performs calculations and controls communication via the communication device 1004, or controls at least one of reading and writing data in the memory 1002 and the storage device 1003.

[0528] The processor 1001, for example, enables the operating system to operate and control the computer as a whole. The processor 1001 may also be composed of a central processing unit (CPU) that includes interfaces with peripheral devices, control devices, arithmetic devices, registers, etc. For example, at least a portion of the control unit 110 (210), the transmit / receive unit 120 (220), etc., described above may also be implemented by the processor 1001.

[0529] Furthermore, the processor 1001 reads programs (program code), software modules, data, etc., from at least one of the storage 1003 and the communication device 1004 into the memory 1002, and performs various processes accordingly. As a program, a program that causes the computer to perform at least a portion of the operations described in the above embodiments can be used. For example, the control unit 110 (210) can also be implemented by a control program stored in the memory 1002 and operated in the processor 1001; similar implementations can be made for other functional blocks.

[0530] The memory 1002 may also be a computer-readable recording medium, such as being composed of at least one of a read-only memory (ROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a random access memory (RAM), or other suitable storage media. The memory 1002 may also be referred to as a register, cache, main memory (main storage device), etc. The memory 1002 is capable of storing executable programs (program code), software modules, etc., for implementing the wireless communication method according to an embodiment of this disclosure.

[0531] Storage device 1003 may also be a computer-readable recording medium, such as a flexible disc, floppy disk, optical disk (e.g., compact disc ROM, CD-ROM), digital multifunction disk, Blu-ray disc, removable disk, hard disk, smart card, flash memory device (e.g., card, stick, key drive), stripe, database, server, or at least one other suitable storage medium. Storage device 1003 may also be referred to as an auxiliary storage device.

[0532] The communication device 1004 is hardware (transmitting and receiving device) used for communication between computers via at least one of a wired network and a wireless network. It is also referred to as a network device, network controller, network interface card (NIC), communication module, etc. To implement at least one of, for example, Frequency Division Duplex (FDD) and Time Division Duplex (TDD), the communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. For example, the aforementioned transmit / receive unit 120 (220) and transmit / receive antenna 130 (230) may also be implemented by the communication device 1004. The transmit / receive unit 120 (220) may also be implemented by physically or logically separating the transmit unit 120a (220a) and the receive unit 120b (220b).

[0533] Input device 1005 is an input device that receives input from external sources (e.g., keyboard, mouse, microphone, switch, button, sensor, etc.). Output device 1006 is an output device that performs output to external sources (e.g., display, speaker, light-emitting diode (LED) lamp, etc.). Alternatively, input device 1005 and output device 1006 can also be an integrated structure (e.g., a touch panel).

[0534] Furthermore, the processor 1001, memory 1002, and other devices are connected via a bus 1007 for communicating information. The bus 1007 can be configured as a single bus or as different buses between the devices.

[0535] Furthermore, the base station 10 and the user terminal 20 can also be configured to include hardware such as a microprocessor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA), and can also use this hardware to implement part or all of the functional blocks. For example, the processor 1001 can also be implemented using at least one of these hardware components.

[0536] (Variation example)

[0537] Furthermore, the terms described in this disclosure, as well as those necessary for understanding this disclosure, may be replaced with terms that have the same or similar meanings. For example, channel, symbol, and signal (signal or signaling) may be interchanged. Additionally, a signal may also be a message. A reference signal can also be abbreviated as RS, and may be referred to as pilot, pilot signal, etc., depending on the applied standard. Furthermore, a component carrier (CC) may also be referred to as cell, frequency carrier, carrier frequency, etc.

[0538] A radio frame can also be composed of one or more periods (frames) in the time domain. Each of these periods (frames) that constitute a radio frame can also be called a subframe. Furthermore, a subframe can also be composed of one or more time slots in the time domain. A subframe can also be a fixed time length (e.g., 1 ms) independent of the parameter set (numerology).

[0539] Here, the parameter set can also be communication parameters applied in at least one of the transmission and reception of a signal or channel. For example, the parameter set can also represent at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering processing performed by the transmitter and receiver in the frequency domain, and specific windowing processing performed by the transmitter and receiver in the time domain.

[0540] In the time domain, a time slot can also be composed of one or more symbols (Orthogonal Frequency Division Multiplexing (OFDM) symbols, Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols, etc.). In addition, a time slot can also be a time unit based on a set of parameters.

[0541] A time slot can also contain multiple mini-time slots. Each mini-time slot can also consist of one or more symbols in the time domain. Furthermore, a mini-time slot can also be called a sub-time slot. A mini-time slot can also consist of fewer symbols than a time slot. PDSCH (or PUSCH) transmitted in a time unit larger than a mini-time slot can also be called PDSCH (PUSCH) mapping type A. PDSCH (or PUSCH) transmitted using mini-time slots can also be called PDSCH (PUSCH) mapping type B.

[0542] Radio frames, subframes, time slots, mini-time slots, and symbols all represent time units for transmitting signals. Radio frames, subframes, time slots, mini-time slots, and symbols can also use their respective other names. Furthermore, the time units such as frames, subframes, time slots, mini-time slots, and symbols in this disclosure can be interchanged.

[0543] For example, a subframe can also be called a TTI, multiple consecutive subframes can also be called a TTI, and a time slot or a mini-time slot can also be called a TTI. That is, at least one of a subframe and a TTI can be a subframe in existing LTE (1ms), a period shorter than 1ms (e.g., 1-13 symbols), or a period longer than 1ms. In addition, the unit representing TTI may not be called a subframe, but rather a time slot, mini-time slot, etc.

[0544] Here, TTI refers, for example, to the smallest unit of time for scheduling in wireless communication. For instance, in an LTE system, the base station schedules radio resources (frequency bandwidth, transmit power, etc., available to each user terminal) in TTI units. However, the definition of TTI is not limited to this.

[0545] TTI can also be a unit of time for transmitting channel-coded data packets (transmission blocks), code blocks, codewords, etc., and can also be a unit of processing such as scheduling and link adaptation. In addition, when a TTI is given, the actual time interval (e.g., the number of symbols) mapped to transmission blocks, code blocks, codewords, etc. can be shorter than the TTI.

[0546] Additionally, where a time slot or a mini-time slot is referred to as a TTI, more than one TTI (i.e., more than one time slot or more than one mini-time slot) can also be the minimum time unit for scheduling. Furthermore, the number of time slots (mini-time slots) constituting the minimum time unit of the schedule can also be controlled.

[0547] A TTI with a duration of 1 ms can also be referred to as a normal TTI (TTI in 3GPP Rel.8-12), a standard TTI, a long TTI, a normal subframe, a standard subframe, a long subframe, a time slot, etc. A TTI shorter than a normal TTI can also be referred to as a shortened TTI, a short TTI, a partial TTI (partial or fractional TTI), a shortened subframe, a short subframe, a mini time slot, a sub-time slot, a time slot, etc.

[0548] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) can also be rewritten as a TTI with a duration of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) can also be rewritten as a TTI with a duration of less than a long TTI but more than 1 ms.

[0549] A resource block (RB) is a unit of resource allocation in both the time and frequency domains. In the frequency domain, it can also contain one or more consecutive subcarriers. The number of subcarriers in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers in an RB can also be determined based on the parameter set.

[0550] Furthermore, an RB can contain one or more symbols in the time domain, and can also be a time slot, a mini-time slot, a subframe, or the length of a TTI. A TTI, a subframe, etc., can also be composed of one or more resource blocks.

[0551] In addition, one or more RBs can also be referred to as Physical Resource Blocks (PRBs), Sub-Carrier Groups (SCGs), Resource Element Groups (REGs), PRB pairs, RB pairs, etc.

[0552] In addition, a resource block can also consist of one or more resource elements (REs). For example, an RE can also be a radio resource area consisting of a subcarrier and a symbol.

[0553] The Bandwidth Part (BWP) (also referred to as partial bandwidth, etc.) can also represent a subset of consecutive common resource blocks (RBs) used for a certain parameter set in a carrier. Here, common RBs can also be determined by the index of RBs based on the common reference point of the carrier. PRBs can also be defined in a BWP and appended with numbers within that BWP.

[0554] A BWP can also include a UL BWP (the BWP used by UL) and a DL BWP (the BWP used by DL). For a UE, one or more BWPs can also be set within a single carrier.

[0555] At least one of the configured BWPs can be active, and the UE may not intend to transmit or receive specific signals / channels outside of the active BWPs. Furthermore, the terms "cell," "carrier," etc., in this disclosure can be rewritten as "BWP."

[0556] Furthermore, the structures described above, such as radio frames, subframes, time slots, mini-time slots, and symbols, are merely illustrative. For example, the number of subframes contained in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots contained within a time slot, the number of symbols and RBs contained in a time slot or mini-time slot, the number of subcarriers contained in an RB, and the number of symbols in a TTI, symbol length, and cyclic prefix (CP) length can be varied in many ways.

[0557] Furthermore, the information, parameters, etc., described in this disclosure can be represented by absolute values, relative values ​​with respect to a specific value, or other corresponding information. For example, wireless resources can also be indicated by a specific index.

[0558] In this disclosure, the names used for parameters, etc., are not limiting names in any respect. Furthermore, the mathematical expressions, etc., using these parameters may differ from those explicitly disclosed in this disclosure. Various channels (PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name; therefore, the various names assigned to these various channels and information elements are not limiting names in any respect.

[0559] The information, signals, etc., described in this disclosure can also be represented using any of a variety of different technologies. For example, data, instructions, commands, information, signals, bits, symbols, chips, etc., which may be mentioned throughout the above description, can also be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination thereof.

[0560] Furthermore, information, signals, etc., can be output in at least one of the following directions: from higher level (upper layer) to lower level (lower layer), and from lower layer to higher level. Information, signals, etc., can also be input and output via multiple network nodes.

[0561] Input and output information, signals, etc., can be stored in a specific location (e.g., memory) or managed using a management table. Input and output information, signals, etc., can be overwritten, updated, or appended. Output information, signals, etc., can also be deleted. Input information, signals, etc., can also be sent to other devices.

[0562] The notification of information is not limited to the methods / implementations described in this disclosure, and may also be carried out by other methods. For example, the notification of information in this disclosure may also be implemented by physical layer signaling (e.g., downlink control information (DCI), uplink control information (UCI), etc.), higher layer signaling (e.g., radio resource control (RRC) signaling, broadcast information (Master Information Block (MIB), System Information Block (SIB) etc.), medium access control (MAC) signaling), other signals, or combinations thereof.

[0563] In addition, physical layer signaling can also be referred to as Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signals), L1 control information (L1 control signals), etc. Furthermore, RRC signaling can also be referred to as RRC messages, such as RRC connection setup messages, RRC connection reconfiguration messages, etc. Additionally, MAC signaling can also be notified using, for example, the MAC control element (CE).

[0564] Furthermore, notification of specific information (e.g., a notification of “is X”) is not limited to explicit notification, but can also be implicit (e.g., by not providing that specific information, or by providing other information).

[0565] The determination can be made by a value represented by a single bit (0 or 1), by a true or false value (boolean), or by a numerical comparison (e.g., a comparison with a specific value).

[0566] Whether software is called software, firmware, middleware, microcode, hardware description language, or any other name, it should be broadly interpreted to refer to instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executable files, execution threads, procedures, functions, etc.

[0567] Furthermore, software, instructions, and information can also be sent and received via a transmission medium. For example, when software is sent from a website, server, or other remote source using at least one of wired technologies (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL) etc.) and wireless technologies (infrared, microwave, etc.), at least one of these wired and wireless technologies is included within the definition of a transmission medium.

[0568] The terms “system” and “network” as used in this disclosure are interchangeable. “Network” may also mean devices included in a network (e.g., base stations).

[0569] In this disclosure, the terms “precoding”, “precoder”, “weight (precoding weight)”, “quasi-co-location (QCL)”, “transmission configuration indication state (TCI state)”, “spatial relation”, “spatial domain filter”, “transmit power”, “phase rotation”, “antenna port”, “layer”, “number of layers”, “rank”, “resource”, “resource set”, “beam”, “beamwidth”, “beam angle”, “antenna”, “antenna element”, “panel”, “UE panel”, “transmitting entity”, and “receiving entity” are used interchangeably.

[0570] Furthermore, in this disclosure, the antenna port can also be rewritten with an antenna port used for any signal / channel (e.g., a DeModulation Reference Signal (DMRS) port). In this disclosure, resources can also be rewritten with resources used for any signal / channel (e.g., reference signal resources, SRS resources, etc.). Additionally, resources can also include time / frequency / code / spatial / power resources. Moreover, the spatial domain transmission filter can also include at least one of a spatial domain transmission filter and a spatial domain reception filter.

[0571] The aforementioned groups may include, for example, at least one of the following: spatial relation group, code division multiplexing (CDM) group, reference signal (RS) group, control resource set (CORESET) group, PUCCH group, antenna port group (e.g., DMRS port group), layer group, resource group, beam group, antenna group, panel group, etc.

There are also instances where the terms macro cell, small cell, femtocell, and picocell are used to refer to a base station.

[0578] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be divided into multiple smaller areas, each of which can also provide communication services through a base station subsystem (e.g., a small indoor base station (Remote Radio Head (RRH))). Terms such as "cell" or "sector" refer to a portion or all of the coverage area of ​​at least one of the base station and base station subsystem providing communication services within that coverage area.

[0579] In this disclosure, the information sent by the base station to the terminal can also be rewritten with the control / operation instructed by the base station to the terminal based on that information.

The vehicle 40 includes a drive unit 41, a steering unit 42, an accelerator pedal 43, a brake pedal 44, a gear shift lever 45, left and right front wheels 46, left and right rear wheels 47, an axle 48, an electronic control unit 49, various sensors (including a current sensor 50, a speed sensor 51, a pressure sensor 52, a vehicle speed sensor 53, an acceleration sensor 54, an accelerator pedal sensor 55, a brake pedal sensor 56, a gear shift lever sensor 57, and an object detection sensor 58), an information service unit 59, and a communication module 60.

[0586] The drive unit 41 is comprised of at least one of an engine, a motor, or a combination of an engine and a motor. The steering unit 42 is configured to include at least a steering wheel (also called a handlebar) and to perform directional control on at least one of the front wheel 46 and the rear wheel 47 based on the operation of the steering wheel by the user.

[0587] The electronic control unit 49 consists of a microprocessor 61, a memory (ROM, RAM) 62, and a communication port (e.g., an input / output (IO) port) 63). Signals from various sensors 50-58 present in the vehicle are input into the electronic control unit 49. The electronic control unit 49 can also be referred to as an ECU (Electronic Control Unit).

The information service unit 59 uses information obtained from external devices via the communication module 60, etc., to provide various information / services (e.g., multimedia information / multimedia services) to the occupants of the vehicle 40.

[0590] The information service unit 59 may include input devices that accept input from the outside (e.g., keyboard, mouse, microphone, switch, button, sensor, touch panel, etc.) or output devices that implement output to the outside (e.g., display, speaker, LED light, touch panel, etc.).

[0591] The driver assistance system unit 64 comprises various devices used to provide functions for preventing accidents and reducing the driver's workload, such as millimeter-wave radar, light detection and ranging (LiDAR), cameras, positioning devices (e.g., Global Navigation Satellite System (GNSS)), map information (e.g., High Definition (HD) maps, Autonomous Vehicle (AV) maps), gyroscope systems (e.g., Inertial Measurement Unit (IMU)) and Inertial Navigation System (INS)), artificial intelligence (AI) chips, and AI processors, as well as one or more ECUs that control these devices. Furthermore, the driver assistance system unit 64 sends and receives various information via a communication module 60 and implements driver assistance or autonomous driving functions.

[0592] The communication module 60 can communicate with the microprocessor 61 and the structural elements of the vehicle 40 via the communication port 63. For example, the communication module 60 sends and receives data (information) with the microprocessor 61 and memory (ROM, RAM) 62, and various sensors 50-58 in the drive unit 41, steering control unit 42, accelerator pedal 43, brake pedal 44, gear shift lever 45, left and right front wheels 46, left and right rear wheels 47, axle 48, and electronic control unit 49 of the vehicle 40 via the communication port 63.

[0593] The communication module 60 is controlled by the microprocessor 61 of the electronic control unit 49 and is a communication device capable of communicating with external devices. For example, it can transmit and receive various types of information with external devices via wireless communication. The communication module 60 can be located either inside or outside the electronic control unit 49. The external device can be, for example, the aforementioned base station 10, user terminal 20, etc. Furthermore, the communication module 60 can be, for example, at least one of the aforementioned base station 10 and user terminal 20 (or it can function as at least one of the base station 10 and user terminal 20).

[0594] The communication module 60 can also wirelessly transmit at least one of the following to an external device: signals from the various sensors 50-58 described above that are input to the electronic control unit 49, information obtained based on these signals, and information based on input from an external source (user) obtained via the information service unit 59. The electronic control unit 49, the various sensors 50-58, the information service unit 59, etc., can also be referred to as input units that receive input. For example, the PUSCH transmitted via the communication module 60 can also contain information based on the aforementioned input.

[0595] The communication module 60 receives various information (traffic information, signal information, inter-vehicle information, etc.) sent from external devices and displays it to the information service unit 59 provided by the vehicle. The information service unit 59 can also be referred to as an output unit that outputs information (for example, outputs information to devices such as displays and speakers based on the PDSCH received through the communication module 60 (or data / information decoded from the PDSCH).

[0596] Furthermore, the communication module 60 stores various information received from external devices in a memory 62 that can be used by the microprocessor 61. The microprocessor 61 can also control the drive unit 41, steering unit 42, accelerator pedal 43, brake pedal 44, gear shift lever 45, left and right front wheels 46, left and right rear wheels 47, axle 48, and various sensors 50-58 of the vehicle 40 based on the information stored in the memory 62.

[0597] Furthermore, the base station in this disclosure can also be rewritten as a user terminal. For example, various methods / implementations of this disclosure can be applied to structures where communication between the base station and the user terminal is replaced by communication between multiple user terminals (e.g., also referred to as device-to-device (D2D) or vehicle-to-everything (V2X)). In this case, it can also be configured such that the user terminal 20 has the functions of the base station 10 described above. In addition, terms such as "uplink" and "downlink" can be rewritten as terms corresponding to inter-terminal communication (e.g., "sidelink"). For example, uplink channel, downlink channel, etc., can also be rewritten as sidelink channel.

[0598] Similarly, the user terminal in this disclosure can also be rewritten as a base station. In this case, it can also be configured such that the base station 10 has the functions of the user terminal 20 described above.

[0599] In this disclosure, operations are assumed to be performed by the base station, and sometimes, depending on the circumstances, by its upper node. Clearly, in a network containing one or more network nodes having a base station, various operations for communication with a terminal can be performed by the base station, one or more network nodes other than the base station (e.g., considering a Mobility Management Entity (MME), a Serving-Gateway (S-GW), etc., but not limited to these), or combinations thereof.

[0600] The various methods / implementations described in this disclosure can be used individually or in combination, and can be switched as needed during execution. Furthermore, the processing procedures, timing sequences, flowcharts, etc., of the various methods / implementations described in this disclosure can be rearranged as long as they do not contradict each other. For example, for the method described in this disclosure, the illustrated order is used to indicate various steps, but the order in which they are indicated is not limited.

Furthermore, multiple systems can be combined (e.g., LTE or LTE-A, combinations with 5G, etc.) for application.

[0602] As used in this disclosure, the term "based on" does not mean "based on only" unless otherwise specified. In other words, the term "based on" means both "based on only" and "based on at least".

[0603] Any reference to an element using the designations "first," "second," etc., as used in this disclosure does not comprehensively limit the quantity or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, reference to the first and second elements does not imply that only two elements may be used, or that the first element must take precedence over the second element in some form.

[0604] The term "determining" as used in this disclosure can encompass a wide variety of operations. For example, "determining" can also refer to judging, calculating, computing, processing, deriving, investigating, looking up (search, inquiry) (e.g., searching in a table, database or other data structure), and ascertaining.

[0605] In addition, "judgment (decision)" can also refer to receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, accessing (e.g., accessing data in memory), etc., as situations where "judgment (decision)" is performed.

[0606] Furthermore, "judgment (decision)" can also refer to situations where resolving, selecting, choosing, establishing, or comparing are considered as making a "judgment (decision)". That is, "judgment (decision)" can also refer to certain operations as making a "judgment (decision)". In this disclosure, "judgment (decision)" can also be rewritten in relation to the operations described above.

[0607] Furthermore, in this disclosure, "determine / determining" can also be interchanged with "assume / assuming," "expect / expecting," "consider / considering," etc. Additionally, in this disclosure, "not assuming..." can also be interchanged with "assuming not...".

[0608] In this disclosure, "expect" can also be interchanged with "be expected." For example, "expect(s)..." (where "..." can also be expressed using a that clause, an infinitive to, etc.) can be interchanged with "be expected...". "Does not expect..." can also be interchanged with "be not expected...". Furthermore, "An apparatus A is not expected..." can also be interchanged with "Apparatus B other than apparatus A does not expect..." (for example, if apparatus A is a UE, apparatus B can also be a base station).

[0609] The term "maximum transmit power" as used in this disclosure may refer to the maximum value of the transmit power, the nominal maximum transmit power (the nominal UE maximum transmit power), or the rated maximum transmit power (the rated UE maximum transmit power).

[0610] As used in this disclosure, the terms “connected,” “coupled,” or all variations thereof, refer to all direct or indirect connections or combinations between two or more elements, and can include cases where there is one or more intermediate elements between two mutually “connected” or “coupled” elements. The connections or combinations between elements can be physical, logical, or a combination thereof. For example, “connection” can also be rewritten as “access.”

[0611] In this disclosure, when two elements are connected, it is possible to consider using more than one wire, cable, printed electrical connection, etc. to be "connected" or "combined" with each other, and as several non-limiting and non-exclusive examples, to use electromagnetic energy with wavelengths having wireless frequency domain, microwave region, light (both visible and invisible) region to be "connected" or "combined" with each other.

[0612] In this disclosure, the term "A is different from B" can also mean "A and B are different from each other." Additionally, the term can also mean "A and B are each different from C." Terms such as "separate" and "combined" can also be interpreted in the same way as "different."

[0613] When the terms "include," "including," and variations thereof are used in this disclosure, these terms, like the term "comprising," mean inclusive. Furthermore, the term "or" as used in this disclosure does not mean XOR.

[0614] In this disclosure, for example, in cases where articles are added through translation, such as a, an, and the in English, the disclosure may also include cases where the noun following these articles is in a plural form.

[0615] In this disclosure, words such as "below," "less than," "above," "more than," and "equal to" can be interchanged. Furthermore, in this disclosure, words meaning "good," "bad," "large," "small," "high," "low," "early," "late," "wide," and "narrow" can be interchanged, not limited to the positive, comparative, and superlative degrees. Additionally, in this disclosure, words meaning "good," "bad," "large," "small," "high," "low," "early," "late," "wide," and "narrow" can also be interchanged as expressions accompanied by "i" (where i is any integer), not limited to the positive, comparative, and superlative degrees (e.g., "highest" can also be interchanged with "i-th highest").

[0616] In this disclosure, "of", "for", "regarding", "related to", "associated with", etc., can also be rewritten interchangeably.

[0617] In this disclosure, phrases such as "when A, B", "if A, then B", "B upon A", "B in response to A", "B based on A", "B during / while A", "B before A", "B at (the same time as) / on A", "B after A", "B since A", and "B until A" can be rewritten interchangeably. Furthermore, A and B can be appropriately replaced with nouns, gerunds, or normal sentences, depending on the context. Additionally, the time difference between A and B can be approximately 0 (immediately following or immediately preceding). Moreover, a time offset can be applied to the time A occurs. For example, "A" can also be rewritten interchangeably with "before / after the time offset of A". This time offset (e.g., more than one symbol / slot) can be predetermined or determined by the UE based on the information it is notified of.

[0618] In this disclosure, timing, moment, time, time instance, arbitrary time unit (e.g., time slot, sub-time slot, symbol, subframe), period, opportunity, resource, etc., can also be rewritten to each other.

[0619] The inventions disclosed herein have been described in detail above. However, it will be apparent to those skilled in the art that the inventions disclosed herein are not limited to the embodiments described herein. The description herein is for illustrative purposes only and is not intended to limit the inventions disclosed herein in any way.
