Description

Technical Field

[0001] The present disclosure relates to a terminal, a wireless communication method, and a base station in a next generation mobile communication system. Background Art

[0002] In the Universal Mobile Telecommunications System (UMTS) network, Long Term Evolution (LTE) is standardized for the purpose of further high-speed data rate, low latency, etc. (Non-Patent Document 1). In addition, LTE-Advanced (3GPP Rel. 10-14) is standardized for the purpose of further increasing capacity and sophistication of LTE (3rd Generation Partnership Project (3GPP)) versions (Release (Rel.) 8, 9).

[0007] Problems to be solved by the invention

[0008] In future wireless communication systems, UE will be able to use one of multiple panels (or multiple beams) for uplink (UL) transmission. In addition, after Rel.18, in order to improve the throughput / reliability of UL, research is being conducted on supporting simultaneous UL transmission using multiple panels (e.g., simultaneous multi-panel UL transmission (SiMPUL)) for more than one transmission / reception point (Transmission / Reception Point (TRP)).

[0009] However, there is insufficient research on how to control UL transmission using multiple panels (eg, simultaneous UL transmission). If UL transmission using multiple panels cannot be properly performed, there is a concern that system performance may be degraded, such as a decrease in throughput.

[0010] Therefore, one of the objects of the present disclosure is to provide a terminal, a wireless communication method, and a base station that can appropriately control UL transmission even when UL transmission is performed using a plurality of panels.

[0032] (PUCCH format)

[0033] In NR, the structure (also called format, PUCCH format (PF), etc.) for the uplink control channel (e.g., PUCCH) is used in the transmission of uplink control information (UCI). For example, in Rel.15NR, Figures 1A to 1E As shown, PF0 to 4 are supported. In Rel. 17 and later, the names of the PFs shown below are only examples, and different names may be used.

[0034] For example, PF0 and 1 are PFs used in the transmission of UCI of less than 2 bits (up to 2 bits). For example, UCI may also be at least one of delivery confirmation information (also called Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK)), confirmation (acknowledgement (ACK)) or negative confirmation (negative-acknowledgement (NACK)), and scheduling request (SR). PF0 can be allocated 1 or 2 code elements, so it is also called short PUCCH. On the other hand, PF1 can be allocated 4-14 code elements, so it is also called long PUCCH, etc. PF0 uses a cyclic shift (CS) that depends on the value of UCI to send a sequence obtained by cyclic shift of a base sequence, so it is also called sequence-based PUCCH. In PF1, multiple user terminals may be code-division multiplexed (CDM) in the same physical resource block (PRB) by using block spreading in the time domain using at least one of CS and time domain (TD)-orthogonal cover code (OCC). PF0 and 1 may also be mapped to 1 PRB.

[0035] PF2-4 is a PF used in the transmission of UCI of more than 2 bits (more than 2 bits) (for example, Channel State Information (CSI)), or at least one of CSI, HARQ-ACK and SR). PF2 can be allocated to 1 or 2 codewords, so it is also called short PUCCH, etc. On the other hand, PF3 and 4 can be allocated to 4-14 codewords, so they are also called long PUCCH, etc. In PF4, block spreading before DFT (frequency domain (FD)-OCC) can also be used, and multiple user terminals are CDM. PF2 and 3 can also be mapped to 1 to 16 PRBs. PF4 can also be mapped to 1 PRB.

[0036] PF1-4 transmits UCI and DMRS in the resource blocks allocated to PUCCH, so it is also called DMRS-based PUCCH. In PF1, 3, and 4, UCI and DMRS are time-division multiplexing (TDM). In PF2, DMRS is mapped to every 3 subcarriers, and UCI and DMRS are frequency-division multiplexing (FDM).

[0037] For PF1, PF3, and PF4, intra-slot frequency hopping can also be applied. If the length of PUCCH is set to N symb , then the length before frequency hopping (first hop) can also be floor(N symb / 2), the length after frequency hopping (second hop) can also be ceil(N symb / 2).

[0038] The waveforms of PF0, PF1, and PF2 may also be Cyclic Prefix (CP)-Orthogonal Frequency Division Multiplexing (OFDM). The waveforms of PF3 and PF4 may also be Discrete Fourier Transform (DFT)-spread(s)-OFDM.

[0039] The allocation of resources (eg, PUCCH resources) used for transmission of the uplink control channel is performed using higher layer signaling and / or downlink control information (DCI).

[0040] Specifically, for a UE, one or more sets (PUCCH resource sets) each including one or more PUCCH resources are notified (configured) through high-layer signaling. For example, for a user terminal, K (for example, 1≤K≤4) PUCCH resource sets may also be notified from the network (for example, a base station). Each PUCCH resource set may also include M (for example, 1≤M≤32) PUCCH resources.

[0041] The UE may also determine a single PUCCH resource set (first PUCCH resource set) from the configured K PUCCH resource sets based on the UCI payload size (UCI payload size, number of UCI information bits). The UCI payload size may also be the number of UCI bits excluding cyclic redundancy check (CRC) bits.

[0042] The UE may also determine the PUCCH resource used for transmitting the UCI from the M PUCCH resources included in the determined PUCCH resource set based on the DCI and at least one of implicit information (also referred to as implicit indication information or implicit index, etc.). For example, the implicit indication information may also be the starting CCE index of the PDCCH receiving the DCI.

[0043] Each PUCCH resource configured for the UE may include the value of at least one of the following parameters (also referred to as a field or information, etc.): In addition, for each parameter, a range of values ​​that can be taken for each PUCCH format may be determined.

[0044] The symbol that starts the allocation of PUCCH (start symbol)

[0045] The number of symbols allocated to the PUCCH in a slot (the period allocated to the PUCCH)

[0046] The index of the resource block (Physical Resource Block (PRB)) where PUCCH allocation starts

[0047] The number of PRBs allocated to PUCCH

[0048] Whether to activate frequency hopping for PUCCH

[0049] The frequency resource of the second hop when frequency hopping is valid, and the index of the initial cyclic shift (CS: CyclicShift)

[0050] The index of the orthogonal spreading code (e.g., orthogonal cover code (OCC)) in the time domain, the length of the OCC used in block spreading before discrete Fourier transform (DFT) (also called OCC length, spreading rate, etc.)

[0051] The OCC index used in block-wise spreading after DFT uses a low-power to average power ratio (low PAPR) sequence in the UCI of PF0 / PF1 and the DMRS of PF1 / PF3 / PF4. A pseudo-random sequence (Gold sequence) is used in the DMRS of PF2.

[0052] (simultaneous multi-panel UL transmission (SiMPUL))

[0053] In future wireless communication systems (e.g., Rel. 18 and later), in order to improve UL throughput / reliability, research is being conducted on supporting simultaneous UL transmission using multiple panels (e.g., simultaneous multi-panel UL transmission (SiMPUL)) for more than one transmission / reception point (Transmission / Reception Point (TRP)).

[0054] In simultaneous UL transmission using multiple panels, the UE may also transmit multiple physical uplink control channels (PUCCH).

[0055] Hereinafter, in the present disclosure, the case where the number of the plurality of panels is two is described as an example, but the number of the panels may be greater than 3. In other words, the number of panels, 2, may be rewritten as a number greater than 3.

[0056] As a transmission method of simultaneous UL transmission using multiple panels for PUCCH, the following schemes 1 and 2 are studied.

[0057] [Solution 1]

[0058] The two PUCCH resources overlap in the time domain and are transmitted simultaneously. The two PUCCH resources are associated with a different panel / beam (see Figure 2A ). The two beams are sent towards their respective TRPs.

[0059] [Solution 2]

[0060] One PUCCH resource is sent simultaneously using two panels / spatial relationships. One PUCCH resource is associated with two panels / beams (refer to Figure 2B ). The two beams are sent towards their respective TRPs.

[0061] In addition, scheme 2 can also be applied to the repeated transmission (repetition) of PUCCH in SFN (single frequency network).

[0062] As of Rel. 17, when two PUCCHs / PUSCHs of different priorities are transmitted, the UE first eliminates the overlap of the PUCCH / PUSCH transmission with a smaller (lower) priority index.

[0063] In case of supporting multiplexing of UCI of different priorities, first, the UE eliminates the overlap of PUCCH / PUSCH transmissions of larger (higher) priority indexes.

[0064] Second, the UE eliminates the overlap of PUCCH transmissions with different priority indices.

[0065] Third, the UE eliminates the overlap of PUCCH and PUSCH transmissions with different priority indices.

[0066] When multiplexing of UCIs of different priorities is not supported, the UE cancels / drops the PUCCH / PUSCH with a smaller priority index according to rules predefined in the specification.

[0067] However, the operation of the UE for overlapping PUCCH transmissions in the case of supporting simultaneous transmission of multiple panels for multiple PUCCHs (e.g., PUCCH / UCI of different priorities) is not clear. In the case of this ambiguity, there is a concern that system performance may be reduced, such as a reduction in throughput.

[0068] Therefore, the inventors of the present invention have conceived a method of appropriately controlling UL transmission even when UL transmission is performed using a plurality of panels.

[0069] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. The wireless communication methods according to the embodiments may be applied individually or in combination.

[0070] In the present disclosure, "A / B" and "at least one of A and B" may be replaced with each other. In addition, in the present disclosure, "A / B / C" may also mean "at least one of A, B, and C".

[0071] In the present disclosure, activation, deactivation, indication (or indication), selection, configuration, update, determination, etc. may also be mutually rewritten. In the present disclosure, support, supported, configured, control, controllable, operation, operationable, etc. may also be mutually rewritten.

[0072] In the present disclosure, Radio Resource Control (RRC), RRC parameters, RRC messages, high-layer parameters, information elements (IE), settings, etc. can also be overwritten with each other. In the present disclosure, Medium Access Control (MAC) control elements (MAC Control Element (CE)), update commands, activation / deactivation commands, etc. can also be overwritten with each other.

[0073] In the present disclosure, the high-layer signaling may be, for example, any one of Radio Resource Control (RRC) signaling, Medium Access Control (MAC) signaling, broadcast information, etc., or a combination thereof.

[0074] In the present disclosure, MAC signaling may use, for example, MAC Control Element (MACCE), MAC Protocol Data Unit (MAC Protocol Data Unit (PDU)), etc. Broadcast information may also be, for example, Master Information Block (MIB), System Information Block (SIB), minimum system information (Remaining Minimum System Information (RMSI)), Other System Information (Other System Information (OSI)), etc.

[0075] In the present disclosure, the physical layer signaling may be, for example, downlink control information (Downlink Control Information (DCI)), uplink control information (Uplink Control Information (UCI)), etc.

[0076] In the present disclosure, index, identifier (ID), indicator, resource ID, etc. may also be mutually overwritten. In the present disclosure, sequence, list, set (set), group, cluster, subset, etc. may also be mutually overwritten.

[0077] In the present disclosure, a panel, a UE panel, a panel group, an antenna group, a UE capability value (UE Capability value), a UE capability value set (UE Capability value set), a specific (pool) index included in a PUSCH setting, a specific (pool) index included in a PUCCH setting, a specific (pool) index included in an SRS setting, a beam, a beam group, a precoder, an uplink (Uplink (UL)) transmitting entity, a transmission / reception point (Transmission / Reception Point (TRP))), a base station, Spatial Relation Information (Spatial Relation Information (SRI)), a spatial relationship, an SRS Resource Indicator (SRS Resource Indicator (SRI)), a control resource set (COntrol REsource SET (CORESET)), a physical downlink shared channel (Physical Downlink Shared Channel (PDSCH)), a codeword (Codeword (CW)), a transport block (Transport Block (TB)), a reference signal (Reference Signal (RS)), an antenna port (e.g., a demodulation reference signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal (DeModulation Reference Signal ( The UE capability value set may also overwrite each other. The UE capability value set may also include, for example, the maximum number of SRS ports supported.

[0078] In addition, the spatial relationship information identifier (Identifier (ID)) (TCI state ID) and the spatial relationship information (TCI state) can also be overwritten with each other. "Spatial relationship information" can also be overwritten with "a collection of spatial relationship information", "one or more spatial relationship information", etc. TCI state and TCI can also be overwritten with each other.

[0079] In the present disclosure, discard, suspend, cancel, puncture, rate matching, postpone, etc. can also be rewritten to each other.

[0080] In each embodiment of the present disclosure, a multi-DCI is set to use a multi-TRP, a CORESET pool index (RRC parameter "coresetPoolIndex") is not provided, and in the activation BWP of the serving cell, a CORESET pool index (RRC parameter "coresetPoolIndex") of a first value (for example, 0) is provided for one or more first CORESETs and a CORESET pool index (RRC parameter "coresetPoolIndex") of a second value (for example, 1) is provided for one or more second CORESETs may also overwrite each other.

[0081] In addition, in each embodiment of the present disclosure, for convenience, an index is marked in the PUCCH format, but the index of the PUCCH format is just an example and is not limited to this. In other words, the PUCCH format of the present disclosure can also be expressed as the function / feature of the PUCCH format as described above.

[0082] In addition, although CSI, HARQ-ACK, and SR are described as UCI in the present disclosure, these statements may be appropriately replaced with each other.

[0083] (Wireless Communication Method)

[0084] PUCCH resources and panels of UCI (eg, SR / HARQ-ACK / CSI) may also be associated based on a specific method.

[0085] This association can be set to the UE using higher layer signaling (for example, RRC / MAC CE), can be indicated to the UE using DCI, or can be notified to the UE by combining RRC / MAC CE / DCI.

[0086] The panel can be associated with the PUCCH resources or with the spatial relationship information / TCI status of the PUCCH resources.

[0087] UCI (eg, SR / HARQ-ACK / CSI reporting) and panels may also be associated based on a specific method.

[0088] This association can be set to the UE using higher layer signaling (for example, RRC / MAC CE), can be indicated to the UE using DCI, or can be notified to the UE by combining RRC / MAC CE / DCI.

[0089] The panel may be associated with the PUCCH resources of the UCI, and may also be associated with at least one of the CSI report settings, the SR settings, and the PDCCH / PDSCH corresponding to the HARQ-ACK information.

[0090] Each embodiment / method / option / selection in the present disclosure may also apply at least one of a single DCI using multiple TRPs and multiple DCI using multiple TRPs.

[0091] In the following embodiments and drawings of the present disclosure, the situation in which PUCCH / CSI / HARQ-ACK / SR overlap in the time domain is described. The overlap may mean that the PUCCH resources are completely overlapped, or that at least a part of the PUCCH resources are overlapped, or that the time resources of a certain PUCCH resource are completely contained in the time resources of other PUCCH resources.

[0092] Hereinafter, each embodiment of the present disclosure can also be used when the above-mentioned scheme 1 / 2 is applied.

[0093] <First embodiment>

[0094] (Analysis 1)

[0095] Up to Rel.16 / 17, the UE can also send a maximum of two PUCCH resources in one time slot.

[0096] When the HARQ-ACK feedback mode is not set to separate (for example, when the RRC parameter is not ackNackFeedbackMode=separate), at least one of the two PUCCH resources in one slot becomes PUCCH format 0 or 2.

[0097] These limitations arise from the fact that in the PUCCH of Rel. 15, there is no use case for time division multiplexing (TDM) two long PUCCHs (eg, a 7-symbol PUCCH and a 7-symbol PUCCH) within 1 slot.

[0098] However, in the case of supporting simultaneous transmission using multiple panels for multiple PUCCHs (eg, PUCCH / UCI of different priorities), it is unclear whether these restrictions are applied.

[0099] In the following, in the first embodiment, the number of PUCCHs (resources) that can be transmitted by the UE is described.

[0100] When the UE supports simultaneous multi-panel transmission of PUCCH, the number of PUCCHs that the UE can transmit in a time slot in a certain CC (cell) may also follow at least one of the following options 1-0 and 1-1.

[0101] 《Option 1-0》

[0102] The UE may also send a maximum of M (M is a specific integer, such as 2) PUCCHs in one time slot in a certain CC (cell) across multiple (eg, all) panels.

[0103] At this time, at least one of the multiple (eg, two) PUCCHs may also be limited to a specific PUCCH format. For example, the specific PUCCH format may also be a PUCCH format with a relatively short number of symbols (eg, PUCCH format 0 / 2, short PUCCH).

[0104] The restriction related to the PUCCH format may be applied only when a specific higher layer parameter is not set as a specific condition (for example, when the RRC parameter does not become ackNackFeedbackMode=separate).

[0105] 《Option 1-1》

[0106] The UE may also send a total of N (N is an integer) PUCCHs in one time slot in a CC (cell).

[0107] The N may also be an integer greater than 2.

[0108] For example, when PUCCH is transmitted (simultaneously) in two panels, N=2×M (M is a specific integer, such as 2). Also, for example, when PUCCH is transmitted (simultaneously) in X panels, N=X×M.

[0109] The UE may also transmit a maximum of two PUCCHs in different symbols in a slot in a certain CC (cell) for PUCCHs associated with the same panel.

[0110] At least one of the two PUCCHs associated with the same panel in one time slot may also be a specific PUCCH format. For example, the specific PUCCH format may also be a PUCCH format with a relatively short number of symbols (eg, PUCCH format 0 / 2, short PUCCH).

[0111] The restriction related to the PUCCH format may be applied only when, for example, multiple DCI using multiple TRPs is configured and specific higher layer parameters are not configured as specific conditions (for example, when the RRC parameter does not become ackNackFeedbackMode=separate).

[0112] Figure 3 is a diagram showing an example of the number of PUCCHs involved in option 1-1. Figure 3 In the example shown, the UE transmits a total of four PUCCHs (PUCCH#1-#4) across two panels in one slot.

[0113] exist Figure 3 In the example shown, a maximum of two PUCCHs are associated with one panel in one time slot. Here, PUCCH #1 and #2 are associated with panel #1, and PUCCH #3 and #4 are associated with panel #2. For PUCCHs corresponding to the same panel, the same hatching is applied. In the following, in the figures showing the associations related to PUCCH / UCI, PUCCH / UCI with the same hatching means that they are associated with the same panel.

[0114] According to the above first embodiment, even when simultaneous transmission using a plurality of panels is applied, the maximum number of PUCCHs in one slot can be appropriately determined.

[0115] <Second embodiment>

[0116] (Analysis 2)

[0117] In Rel.16 / 17, when the UE is configured with PUCCH resources for multiple CSIs in one time slot and the RRC parameters related to the multiple PUCCH resource lists for CSI (multi-CSI-PUCCH-ResourceList) are not configured, the UE determines the two PUCCH resources in one time slot according to the priority of the CSI report.

[0118] In this case, first, the UE determines the PUCCH resource (first resource) corresponding to the CSI report with the maximum (highest) priority.

[0119] Second, the UE determines the PUCCH resource (second resource) corresponding to the CSI report with the highest priority among the CSI reports corresponding to the remaining resources except the first resource.

[0120] When the first resource is in PUCCH format 2, the remaining resources other than the first resource become resources that do not overlap with the first resource in the time slot.

[0121] When the first resource is in PUCCH format 3 or 4, the remaining resources except the first resource become PUCCH format 2 resources that do not overlap with the first resource in the slot.

[0122] In Rel. 16 / 17, when PUCCH resources for multiple CSIs are configured in one slot for a UE and RRC parameters related to multiple PUCCH resource lists for CSI (multi-CSI-PUCCH-ResourceList) are configured, the UE multiplexes all CSI reports in one resource.

[0123] However, in the case of supporting simultaneous transmission using multiple panels for multiple PUCCHs, the operation of the UE when multiple PUCCH resources associated with multiple panels for CSI are configured in one time slot is unclear.

[0124] Hereinafter, in the second embodiment, simultaneous transmission using multiple panels of PUCCH for multiple CSIs will be described.

[0125] The UE may also support simultaneous multi-panel transmission of the PUCCH. The UE may also be configured to simultaneously transmit multiple panels of the PUCCH. This configuration may also be performed using specific high-layer parameters.

[0126] In the case where the UE is configured with multiple PUCCH resources for CSI within one time slot, and multiple (e.g., two) PUCCHs for multiple (e.g., two) CSI reports are associated with the same panel, the UE may also follow at least one of options 2-A-1 to 2-A-3 described below.

[0127] The UE may also multiplex / map multiple (eg, two) CSI reports associated with the same panel in one PUCCH (option 2-A-1).

[0128] The UE may also not multiplex / map multiple (eg, two) CSI reports associated with the same panel in one PUCCH (option 2-A-2).

[0129] The UE may be configured to determine which of the above options 2-A-1 and 2-A-2 to apply (option 2-A-3) by using higher layer signaling (RRC / MAC CE).

[0130] In option 2-A-3, this setting can also be made for each panel.

[0131] In the case where the UE is configured with multiple PUCCH resources for CSI within one time slot, and multiple (e.g., two) PUCCHs for multiple (e.g., two) CSI reports are associated with different panels, the UE may also follow at least one of options 2-B-1 to 2-B-3 described below.

[0132] The UE may also multiplex / map multiple (eg, two) CSI reports associated with different panels in one PUCCH (option 2-B-1).

[0133] The UE may also not multiplex / map multiple (eg, two) CSI reports associated with different panels in one PUCCH (option 2-B-2).

[0134] The UE may be configured to determine which of the above options 2-B-1 and 2-B-2 to apply (option 2-B-3) by using higher layer signaling (RRC / MAC CE).

[0135] In option 2-B-3, this setting can also be made for each panel / each panel pair.

[0136] Method 2-1

[0137] The UE may also support simultaneous multi-panel transmission of PUCCH.

[0138] For the UE, multiple PUCCH resources for CSI may be configured in one time slot.

[0139] This method can also be applied to the combination of the above-mentioned options 2-A-1 and 2-B-1, for example.

[0140] The UE may also follow operations specified in existing specifications (eg, Rel. 16).

[0141] For example, the UE may determine a PUCCH resource according to RRC parameters related to multiple PUCCH resource lists for CSI (e.g., multi-CSI-PUCCH-ResourceList) and follow specific rules. The UE may also multiplex / map multiple (e.g., all) CSIs in the determined PUCCH resource.

[0142] Figure 4is a diagram showing an example of multiplexing / mapping of CSI involved in method 2-1. Figure 4 In the example shown, four CSI reports (CSI#1-#4) are configured for the UE in one time slot. The PUCCH resources corresponding to CSI#1 and #2 are associated with a certain panel (panel #1), and the PUCCH resources corresponding to CSI#1 and #2 are associated with another panel (panel #2).

[0143] exist Figure 4 In the example shown, the UE multiplexes / maps CSI#1-#4 in one resource and transmits them.

[0144] Method 2-2

[0145] The UE may also support simultaneous multi-panel transmission of PUCCH.

[0146] For the UE, multiple PUCCH resources for CSI may be configured in one time slot.

[0147] This method can also be applied to the combination of the above-mentioned options 2-A-2 and 2-B-2, for example.

[0148] The UE may also follow at least one of the following options 2-2-0 and 2-2-1.

[0149] [Option 2-2-0]

[0150] The UE may also determine multiple (eg, two) PUCCH resources for CSI reporting across multiple (eg, all) panels.

[0151] The UE may determine the PUCCH resource (first resource) corresponding to the CSI report with the maximum (highest) priority among the CSI reports associated with any panel.

[0152] The UE may determine the PUCCH resource (second resource) corresponding to the CSI report with the highest priority among the CSI reports corresponding to the remaining resources other than the first resource and associated with any panel.

[0153] When the first resource is a first PUCCH format (e.g., a relatively short PUCCH format, a short PUCCH, or a PUCCH format 2), the remaining resources other than the first resource may also be resources that do not overlap with the first resource in the time slot. At this time, the remaining resources may also be associated with any panel.

[0154] When the first resource is a second PUCCH format (relatively long PUCCH format, long PUCCH, PUCCH format 3 / 4), the remaining resources other than the first resource may also be resources of the first PUCCH format that do not overlap with the first resource in the time slot. At this time, the remaining resources may also be associated with any panel.

[0155] Resources other than the first and second resources mentioned above may also be discarded.

[0156] Figure 5A is a diagram showing an example of the association between CSI and PUCCH resources involved in option 2-2-0. Figure 5A In the example shown, four CSI reports (CSI#1-#4) are set in one time slot. The PUCCH resources corresponding to CSI#1 and #2 are associated with a certain panel (panel #1), and the PUCCH resources corresponding to CSI#1 and #2 are associated with another panel (panel #2). The priority of CSI is CSI#1>CSI#2>CSI#3>CSI#4.

[0157] exist Figure 5A In the example shown, the UE determines the PUCCH resource corresponding to the highest priority CSI#1 as the first resource across all panels (panels #1 and #2). The UE determines the PUCCH resource corresponding to the highest priority CSI#2 as the second resource for the remaining CSIs except the CSI corresponding to the first resource across all panels (panels #1 and #2). At this time, CSI#3 and #4 are discarded.

[0158] [Option 2-2-1]

[0159] For each panel, the UE may also determine multiple (eg, two) PUCCH resources within one time slot for CSI reporting.

[0160] For each panel, the UE may determine the PUCCH resource (first resource) corresponding to the CSI report with the maximum (highest) priority among the CSI reports associated with the panel.

[0161] For each panel, the UE may determine the PUCCH resource (second resource) corresponding to the CSI report with the highest priority among the CSI reports corresponding to the remaining resources other than the first resources and associated with the panel.

[0162] When the first resource is a first PUCCH format (e.g., a relatively short PUCCH format, a short PUCCH, a PUCCH format 2), the remaining resources other than the first resource may also be resources that do not overlap with the first resource in the time slot. At this time, the remaining resources may also be associated with the same panel.

[0163] When the first resource is a second PUCCH format (relatively long PUCCH format, long PUCCH, PUCCH format 3 / 4), the remaining resources other than the first resource may also be resources of the first PUCCH format that do not overlap with the first resource in the time slot. At this time, the remaining resources may also be associated with the same panel.

[0164] For each panel, resources other than the first and second resources may also be discarded.

[0165] Figure 5B FIG. 2 is a diagram showing an example of the association between CSI and PUCCH resources involved in Option 2-2-1. Figure 5B In the example shown, four CSI reports (CSI#1-#4) are set in one time slot. The PUCCH resources corresponding to CSI#1 and #2 are associated with a certain panel (panel #1), and the PUCCH resources corresponding to CSI#1 and #2 are associated with another panel (panel #2). The priority of CSI is CSI#1>CSI#2>CSI#3>CSI#4.

The UE determines the PUCCH resource corresponding to the highest priority CSI#2 as the second resource for the remaining CSI in panel #1 except for the CSI corresponding to the first resource.

[0167] exist Figure 5B In the example shown, the UE determines the PUCCH resource corresponding to the highest priority CSI #3 as the first resource in panel #2. In panel #2, the UE determines the PUCCH resource corresponding to the highest priority CSI #4 as the second resource for the remaining CSI except the CSI corresponding to the first resource.

[0168] Method 2-3

[0169] The UE may also support simultaneous multi-panel transmission of PUCCH.

[0170] For the UE, multiple PUCCH resources for CSI may be configured in one time slot.

[0171] This method can also be applied to the combination of the above-mentioned options 2-A-1 and 2-B-2, for example.

[0172] For each panel, the UE may also multiplex / map multiple (eg, all) CSI reports associated with the same panel in one resource.

[0173] For each panel, the one resource may also be determined according to a specific rule based on an RRC parameter (e.g., multi-CSI-PUCCH-ResourceList) related to a CSI PUCCH resource list associated with the panel. At this time, the UE may also follow at least one of the following changes 2-3-1 and 2-3-2.

[0174] [Change 2-3-1]

[0175] A list of resources may be set for the UE. The list of resources may include resources across multiple (eg, all) panels. For each panel, the resource may be determined from resources associated with the panel in the list.

[0176] [Change 2-3-2]

[0177] For each panel, a list of resources may be set for the UE. For each panel, the one resource may be determined from a list of resources associated with the panel.

[0178] In mode 2-3, the UE may also simultaneously transmit multiple (eg, two) PUCCH resources associated with multiple (eg, two) panels. Each of the multiple PUCCH resources may also include one or more CSIs associated with the same panel.

[0179] Figure 6 2-3 is a diagram showing an example of the association between CSI and PUCCH resources. Figure 6 In the example shown, four CSI reports (CSI#1-#4) are configured in one time slot. The PUCCH resources corresponding to CSI#1 and #2 are associated with a certain panel (panel #1), and the PUCCH resources corresponding to CSI#1 and #2 are associated with another panel (panel #2).

[0180] exist Figure 6 In the example shown, the UE multiplexes / maps CSI #1 and #2 in the resources associated with panel #1. The UE multiplexes / maps CSI #3 and #4 in the resources associated with panel #2. The resources are determined from a list of resources based on a specific rule.

[0181] According to the second embodiment described above, even when a plurality of CSIs overlap when a plurality of panels are simultaneously transmitted using the PUCCH, the plurality of CSIs can be appropriately transmitted.

[0182] <Third embodiment>

[0183] (Analysis 3)

[0184] In Rel.16 / 17, except when the UE is configured to use multi-DCI of multiple TRPs and the HARQ-ACK feedback mode is set to separate (for example, when the RRC parameter becomes ackNackFeedbackMode=separate) (also referred to as Case 1), for multiple PUCCH resources containing HARQ-ACK information indicated in the same time slot, the UE multiplexes / maps all HARQ-ACK information in one PUCCH resource.

[0185] In Rel.16 / 17, when the UE is configured to use multi-DCI with multiple TRPs and the HARQ-ACK feedback mode is set to separate (also referred to as situation 2), for multiple PUCCH resources containing HARQ-ACK information indicated in the same time slot, the UE multiplexes / maps HARQ-ACK information associated with the same CORESET pool index in one PUCCH resource for each CORESET pool index (coresetPoolIndex). At this time, the UE multiplexes / maps different HARQ-ACK information corresponding to different CORESET pool indexes in different PUCCH resources. The UE does not expect multiple PUCCH resources for multiple CORESET pool indexes to overlap.

[0186] However, in the case of supporting simultaneous transmission using multiple panels for multiple PUCCHs, that is, in a case equivalent to the above-mentioned situation 1 / 2, the operation of the UE related to the PUCCH resources used for HARQ-ACK information is not clear.

[0187] Hereinafter, in the third embodiment, simultaneous transmission using multiple panels for PUCCHs for multiple HARQ-ACKs will be described.

[0188] The UE may also support simultaneous multi-panel transmission of the PUCCH. The UE may also be configured to simultaneously transmit multiple panels of the PUCCH. This configuration may also be performed using specific high-layer parameters.

[0189] This embodiment can also be applied, for example, when multiple DCI using multiple TRPs is configured for the UE and specific higher layer parameters are set as specific conditions (for example, when the RRC parameter is ackNackFeedbackMode=separate).

[0190] For multiple PUCCH resources containing HARQ-ACK information indicated in the same time slot, the UE can also multiplex / map the HARQ-ACK information associated with the same CORESET pool index (coresetPoolIndex) in one PUCCH resource.

[0191] The UE may also multiplex / map different HARQ-ACK information corresponding to different CORESET pool indexes in different PUCCH resources.

[0192] The UE may also make an assumption as to whether the PUCCH resources overlap in the time domain based on whether the PUCCH resources (multiple PUCCH resources) corresponding to each of the multiple HARQ-ACK information indicated in the same time slot are associated with the same CORESET pool index.

[0193] The UE may also follow at least one of the following options 3-0 and 3-1.

[0194] Option 3-0

[0195] Regardless of whether multiple (e.g., two) PUCCH resources associated with different CORESET pool indices (coresetPoolIndex) are associated with the same panel or with different panels, the UE may not expect / assume that the multiple (e.g., two) PUCCH resources overlap (in the time domain).

[0196] 《Option 3-1》

[0197] In the case where each of the PUCCH resources (multiple PUCCH resources) corresponding to each of multiple (e.g., two) CORESET pool indices is associated with the same panel, the UE may not expect / assume that the multiple PUCCH resources overlap (in the time domain).

[0198] In the case where each of the PUCCH resources (multiple PUCCH resources) corresponding to each of multiple (e.g., two) CORESET pool indexes is associated with a different panel, the UE may also follow at least one of the following options 3-1-1 to 3-1-3.

[0199] [Select 3-1-1]

[0200] The UE may not expect / assume that each (plurality of PUCCH resources) associated with different panels overlaps (in the time domain).

[0201] [Select 3-1-2]

[0202] The UE may also expect / assume that each (a plurality of PUCCH resources) associated with different panels overlaps (in the time domain). In this case, the UE may also transmit the plurality of PUCCH resources simultaneously (overlapping in the time domain).

[0204] exist Figure 7 In the example shown, the UE is configured with two HARQ-ACKs (HARQ-ACK #1 and #2) / PUCCHs associated with different CORESET pool indices corresponding to different panels. Figure 7 In the example shown, the UE sends each HARQ-ACK in the resources associated with the CORESET pool index / panel corresponding to each HARQ-ACK.

[0205] [Select 3-1-3]

[0206] The UE may be configured to determine which of the above options 3-1-1 and 3-1-2 to apply by using higher layer signaling (RRC / MAC CE).

[0211] In Rel.16 / 17, when PUCCH resources using PUCCH format 0 including SR overlap with PUCCH resources using PUCCH format 1 including HARQ-ACK, the UE discards the SR and sends only HARQ-ACK in the resources for HARQ-ACK.

[0212] In Rel.16 / 17, when PUCCH resources using PUCCH format 1 including a positive SR overlap with PUCCH resources using PUCCH format 1 including HARQ-ACK, the UE maps HARQ-ACK to the resources for SR and transmits it.

[0213] In Rel. 16 / 17, when PUCCH resources using PUCCH format 1 including a negative SR overlap with PUCCH resources using PUCCH format 1 including HARQ-ACK, the UE maps HARQ-ACK to the resources for HARQ-ACK and transmits it.

[0214] In Rel.16 / 17, when PUCCH resources including SR overlap with PUCCH resources using PUCCH format 2 / 3 / 4 including HARQ-ACK, the UE multiplexes / maps SR and HARQ-ACK in the resources for HARQ-ACK and transmits them.

[0215] However, in the case of supporting simultaneous transmission using multiple panels for multiple PUCCHs, the transmission operation of the UE related to the PUCCH resources used for SR and HARQ-ACK information is unclear.

[0302] This HARQ-ACK may be, for example, a HARQ-ACK that does not correspond to the scheduling DCI, or a HARQ-ACK that corresponds to the PDSCH of semi-persistent scheduling (SPS).

[0303] According to the sixth embodiment described above, even when CSI and HARQ-ACK overlap when performing simultaneous transmission of a plurality of panels using PUCCH, CSI / HARQ-ACK can be appropriately transmitted.

[0304] <Modification>

[0305] Regarding the setting method for the selection XY-3 (X is an integer from 2 to 6, and Y is 1 or 2) in the second to sixth embodiments, each selection may be set based on different (independent) setting information (signaling).

[0306] Regarding the setting method for the selection XY-3 in the second to sixth embodiments described above, at least two of the selections (or all of the selections) may be set based on common (joint) setting information (signaling).

[0307] In each embodiment of the present disclosure, “associated with different panels” and “associated with the same panel” may be rewritten.

[0308] The UE may also be configured with at least one of the following Mode 1 and Mode 2. This configuration may also be performed based on reported UE capability information.

[0309] Mode 1: Repeated transmission (repetition) of PUCCH using time division multiplexing (TDM) / space division multiplexing (SDM) / frequency division multiplexing (FDM) (for improving reliability).

[0310] Mode 2: PUCCH MIMO (Multi-Input Multi-Output) (for high throughput / high resource efficiency of PUCCH).

[0311] The PUCCH MIMO may also be a MIMO of a rank / layer greater than 1.

[0312] For the above-mentioned solution 1, the UE may also use multiple panels (transmission panels) to transmit UCI using multiple PUCCHs. In this case, the PUCCH resource indicator (PRI) field included in the DCI may also be enhanced to indicate multiple PUCCH resources in one PUCCH resource set.

[0313] For the above-mentioned solution 2, multiple panels (transmission panels) can also be used to use one PUCCH to send UCI. In this case, one PRI field can also be used to indicate one PUCCH resource. For one PUCCH resource, multiple layers / time resources / frequency resources can also be set.

[0314] Similar to the layer mapping for codewords, the layer mapping for UCI can also be standardized / applied.

[0315] <Other embodiments>

[0316] A higher layer parameter (RRC IE) / UE capability corresponding to at least one function (feature) in the above multiple embodiments may also be specified. The UE capability may also indicate support for the function.

[0317] A UE to which the higher layer parameters corresponding to the function are set (to activate the function) can also perform the function. It may also be stipulated that "a UE to which the higher layer parameters corresponding to the function are not set does not perform the function (for example, in accordance with Rel. 15 / 16 / 17)".

[0318] A UE that has reported UE capabilities indicating support for the function may also perform the function. It may also be stipulated that "a UE that has not reported UE capabilities indicating support for the function shall not perform the function (for example, in accordance with Rel. 15 / 16 / 17)".

[0319] If the UE reports the UE capability that supports the function and the high-level parameters corresponding to the function are set, the UE may also perform the function. It may also be stipulated that "if the UE does not report the UE capability that supports the function or if the high-level parameters corresponding to the function are not set, the UE does not perform the function (for example, in accordance with Rel.15 / 16 / 17)".

[0320] UE capability may also indicate whether the UE supports the function.

[0321] The function can also be an application of simultaneous UL transmission using multiple panels.

[0322] The UE capability may also be defined by whether it supports simultaneous transmission of multiple (eg, two) PUCCH resources associated with different panels.

[0323] The UE capability may also be defined by whether multiplexing / mapping of (e.g., two) multiple CSI / HARQ-ACK / SR associated with the same / different panels is supported in one PUCCH resource.

[0324] The UE capability may also be defined by whether multiplexing / mapping of (eg, two) SR and HARQ-ACK associated with the same / different panels is supported in one PUCCH resource.

[0325] The UE capability may also be defined by whether multiplexing / mapping of (eg, two) SRs and CSIs associated with the same / different panels is supported in one PUCCH resource.

[0326] The UE capability may also be defined by whether multiplexing / mapping of (eg, two) CSI and HARQ-ACK associated with the same / different panels is supported in one PUCCH resource.

[0327] The UE capability may also be defined by whether it supports at least one of the methods described in the first to sixth embodiments above.

[0328] According to the above other implementation modes, the UE can maintain compatibility with existing specifications and can implement the above functions.

[0329] (Wireless Communication System)

[0330] Hereinafter, a configuration of a wireless communication system according to an embodiment of the present disclosure will be described. In the wireless communication system, communication is performed using any one of the wireless communication methods according to the above-mentioned embodiments of the present disclosure or a combination thereof.

[0331] Fig.131 is a diagram showing an example of a schematic structure of a wireless communication system involved in one embodiment. The wireless communication system 1 may also be a system that implements communication using Long Term Evolution (LTE) standardized by the Third Generation Partnership Project (3GPP), the fifth generation mobile communication system New Radio (5G NR), and the like.

[0332] In addition, the wireless communication system 1 can also support dual connectivity (Multi-RAT Dual Connectivity (MR-DC)) between multiple radio access technologies (Radio Access Technology (RAT)). MR-DC can also include dual connectivity between LTE (Evolved Universal Terrestrial Radio Access (E-UTRA))) and NR (E-UTRA-NR Dual Connectivity (E-UTRA-NR Dual Connectivity (EN-DC))), dual connectivity between NR and LTE (NR-E-UTRA Dual Connectivity (NR-E-UTRA Dual Connectivity (NE-DC))), etc.

[0333] In EN-DC, the base station (eNB) of LTE (E-UTRA) is the master node (Master Node (MN)), and the base station (gNB) of NR is the secondary node (Secondary Node (SN)). In NE-DC, the base station (gNB) of NR is the MN, and the base station (eNB) of LTE (E-UTRA) is the SN.

[0334] The wireless communication system 1 can also support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity (NR-NR Dual Connectivity (NN-DC)) where both MN and SN are NR base stations (gNB)).

[0335] The wireless communication system 1 may also include a base station 11 that forms a macro cell C1 with a relatively wide coverage, and a base station 12 (12a-12c) that is configured in the macro cell C1 and forms a small cell C2 that is narrower than the macro cell C1. The user terminal 20 may also be located in at least one cell. The configuration and number of each cell and user terminal 20 are not limited to the method shown in the figure. Hereinafter, when the base stations 11 and 12 are not distinguished, they are collectively referred to as base stations 10.

[0336] The user terminal 20 may be connected to at least one of the plurality of base stations 10. The user terminal 20 may use at least one of carrier aggregation (CA) using a plurality of component carriers (CC) and dual connectivity (DC).

[0337] Each CC may 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)). The macro cell C1 may also be included in FR1, and the small cell C2 may also be included in FR2. For example, FR1 may be a frequency band below 6 GHz (lower than 6 GHz (sub-6 GHz)), and FR2 may be a frequency band higher than 24 GHz (higher than 24 GHz (above-24 GHz)). In addition, the frequency bands and definitions of FR1 and FR2 are not limited to these. For example, FR1 may also be equivalent to a frequency band higher than FR2.

[0338] Furthermore, the user terminal 20 may perform communication in each CC using at least one of time division duplex (TDD) and frequency division duplex (FDD).

[0339] Multiple base stations 10 may also be connected via wired (e.g., optical fiber based on Common Public Radio Interface (CPRI)), X2 interface, etc.) or wireless (e.g., NR communication). For example, when NR communication between base stations 11 and 12 is used as a backhaul, the base station 11 equivalent to the upper station may also be referred to as an Integrated Access Backhaul (IAB) donor, and the base station 12 equivalent to a relay station (relay) may also be referred to as an IAB node.

[0340] The base station 10 may also be connected to the core network 30 via other base stations 10 or directly. The core network 30 may also include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a Next Generation Core (NGC), and the like.

[0341] The user terminal 20 may also be a terminal that supports at least one of communication modes such as LTE, LTE-A, and 5G.

[0342] In the wireless communication system 1, a wireless access method based on orthogonal frequency division multiplexing (OFDM) may be used. For example, in at least one of the downlink (DL) and the uplink (UL), cyclic prefix OFDM (CP-OFDM), discrete Fourier transform spread OFDM (DFT-s-OFDM), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), etc. may be used.

[0343] The radio access scheme may also be referred to as a waveform. In addition, in the wireless communication system 1, other radio access schemes (for example, other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the radio access schemes for UL and DL.

[0344] In the wireless communication system 1, as downlink channels, a downlink shared channel (Physical Downlink Shared Channel (PDSCH)) shared by each user terminal 20, a broadcast channel (Physical Broadcast Channel (PBCH))), a downlink control channel (Physical Downlink Control Channel (PDCCH)) and the like may be used.

[0345] In addition, in the wireless communication system 1, an uplink shared channel (Physical Uplink Shared Channel (PUSCH)) shared by each user terminal 20), an uplink control channel (Physical Uplink Control Channel (PUCCH))), a random access channel (Physical Random Access Channel (PRACH)) and the like may be used as uplink channels.

[0346] The PDSCH transmits user data, high-layer control information, system information block (SIB), etc. The PUSCH transmits user data, high-layer control information, etc. In addition, the PBCH transmits the master information block (MIB).

[0347] The PDCCH may also transmit lower layer control information. The lower layer control information may include, for example, downlink control information (Downlink Control Information (DCI)) including scheduling information of at least one of the PDSCH and the PUSCH.

[0348] In addition, the DCI for scheduling the PDSCH may also be referred to as DL allocation, DL DCI, etc., and the DCI for scheduling the PUSCH may also be referred to as UL grant, UL DCI, etc. In addition, the PDSCH may also be rewritten as DL data, and the PUSCH may also be rewritten as UL data.

[0349] In the detection of PDCCH, the control resource set (CORESET) and the search space (search space) can also be used. CORESET corresponds to the resources for searching DCI. The search space corresponds to the search area and search method of PDCCH candidates. A CORESET can also be associated with one or more search spaces. The UE can also monitor the CORESET associated with a search space based on the search space setting.

[0350] A search space may also correspond to a PDCCH candidate corresponding to one or more aggregation levels. One or more search spaces may also be referred to as a search space set. In addition, the "search space", "search space set", "search space setting", "search space set setting", "CORESET", "CORESET setting" and the like in the present disclosure may also be rewritten mutually.

[0351] Through PUCCH, uplink control information (uplink control information (UCI)) including at least one of channel state information (CSI), delivery confirmation information (e.g., also called hybrid automatic repeat request confirmation (HARQ-ACK), ACK / NACK, etc.) and scheduling request (SR) can also be transmitted. Through PRACH, random access preambles for establishing a connection with a cell can also be transmitted.

[0352] In the present disclosure, downlink, uplink, etc. may be expressed without the word “link.” In addition, various channels may be expressed without the word “physical” at the beginning.

[0353] In the wireless communication system 1, a synchronization signal (Synchronization Signal (SS)), a downlink reference signal (Downlink Reference Signal (DL-RS)), etc. may also be transmitted. In the wireless communication system 1, a cell-specific reference signal (Cell-specific Reference Signal (CRS)), a channel state information reference signal (Channel State Information Reference Signal (CSI-RS)), a demodulation reference signal (DeModulation Reference Signal (DMRS)), a positioning reference signal (Positioning Reference Signal (PRS)), a phase tracking reference signal (Phase Tracking Reference Signal (PTRS)), etc. may also be transmitted as DL-RS.

[0354] The synchronization signal may be, for example, at least one of a primary synchronization signal (PSS) and a secondary synchronization signal (SSS). A signal block including SS (PSS, SSS) and PBCH (and DMRS for PBCH) may also be referred to as SS / PBCH block, SS block (SSB), etc. In addition, SS, SSB, etc. may also be referred to as reference signals.

[0355] In addition, in the wireless communication system 1, as an uplink reference signal (Uplink Reference Signal (UL-RS)), a measurement reference signal (Sounding Reference Signal (SRS)), a demodulation reference signal (DMRS), etc. can also be transmitted. In addition, DMRS can also be called a user terminal specific reference signal (UE-specific Reference Signal).

[0404] Regardless of whether the first PUCCH resource associated with the CSI and the second PUCCH resource associated with the SR are associated with the same panel, the control unit 210 may also map the CSI and the SR in the first PUCCH resource (fifth embodiment).

[0405] The control unit 210 may also determine the resources to map the CSI and the SR based on whether the first PUCCH resource associated with the CSI and the second PUCCH resource associated with the SR are associated with the same panel (fifth embodiment).

[0406] The control unit 210 may also determine the resources to map the CSI and the HARQ-ACK based on whether the first PUCCH resource associated with the CSI and the third PUCCH resource associated with the HARQ-ACK are associated with the same panel (sixth embodiment).

[0408] In addition, the block diagram used in the description of the above-mentioned embodiment shows a block of a functional unit. These functional blocks (structural units) are implemented by any combination of at least one of hardware and software. In addition, the implementation method of each functional block is not particularly limited. That is, each functional block can be implemented by a device that is physically or logically combined, or two or more devices that are physically or logically separated can be directly or indirectly (for example, by wired, wireless, etc.) connected and implemented by these multiple devices. The functional block can also be implemented by combining the above-mentioned one device or the above-mentioned multiple devices with software.

For example, a functional block (structural unit) that implements a sending function may also be referred to as a transmitting unit, a transmitter, etc. Any one of them is as described above, and the implementation method is not particularly limited.

[0410] For example, a base station, a user terminal, etc. in one embodiment of the present disclosure may also function as a computer that performs processing of the wireless communication method of the present disclosure. Fig.16 1001, memory 1002, storage 1003, communication device 1004, input device 1005, output device 1006, bus 1007, etc.

The hardware structure of the base station 10 and the user terminal 20 may be configured to include one or more of the devices shown in the figure, or may be configured to exclude some of the devices.

[0412] For example, only one processor 1001 is shown, but there may be multiple processors. In addition, the processing may be performed by one processor, or may be performed by two or more processors simultaneously, sequentially, or in other ways. In addition, the processor 1001 may also be implemented by one or more chips.

[0413] The functions of the base station 10 and the user terminal 20 are realized, for example, by reading specific software (program) 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 the reading and writing of data in the memory 1002 and the storage 1003.

[0414] The processor 1001 controls the entire computer by, for example, operating an operating system.

The output device 1006 is an output device that implements output to the outside (e.g., a display, a speaker, a light emitting diode (LED) lamp, etc.). In addition, the input device 1005 and the output device 1006 may also be an integrated structure (e.g., a touch panel).

[0422] (Variation Example)

[0423] In addition, the terms described in the present disclosure and the terms required for understanding the present disclosure may also be replaced with terms having the same or similar meanings. For example, channels, code elements, and signals (signals or signaling) may also be rewritten with each other. In addition, a signal may also be a message. A reference signal may also be referred to as RS, and may also be referred to as a pilot, a pilot signal, etc. depending on the standard applied. In addition, a component carrier (CC) may also be referred to as a cell, a frequency carrier, a carrier frequency, etc.

[0424] A wireless frame may also be composed of one or more periods (frames) in the time domain. Each period (frame) of the one or more periods (frames) constituting a wireless frame may also be referred to as a subframe. Further, a subframe may also be composed of one or more time slots in the time domain. A subframe may also be a fixed time length (e.g., 1 ms) that is not dependent on a parameter set (numerology).

[0425] Here, the parameter set may also be a communication parameter applied in at least one of the transmission and reception of a certain signal or channel. For example, the parameter set may also represent at least one of a subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), the number of symbols per TTI, a wireless frame structure, a specific filtering process performed by a transmitter and receiver in the frequency domain, a specific windowing process performed by a transmitter and receiver in the time domain, and the like.

[0426] A time slot may 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 the time domain. In addition, a time slot may also be a time unit based on a parameter set.

[0427] A time slot may also include multiple mini-slots. Each mini-slot may also be composed of one or more symbols in the time domain. In addition, a mini-slot may also be referred to as a sub-slot. A mini-slot may also be composed of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-slot may also be referred to as a PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a mini-slot may also be referred to as a PDSCH (PUSCH) mapping type B.

[0428] 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 may also be referred to by their respective names. In addition, time units such as frames, subframes, time slots, mini-time slots, and symbols in the present disclosure may also be replaced with each other.

[0429] For example, a subframe may be referred to as a TTI, a plurality of consecutive subframes may be referred to as a TTI, and a time slot or a mini time slot may be referred to as a TTI. That is, at least one of a subframe and a TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (e.g., 1-13 symbols), or a period longer than 1 ms. In addition, the unit representing a TTI may be referred to as a time slot, a mini time slot, etc. instead of a subframe.

[0430] Here, TTI refers to, for example, the minimum time unit for scheduling in wireless communication. For example, in the LTE system, the base station schedules each user terminal to allocate wireless resources (frequency bandwidth, transmission power, etc. that can be used in each user terminal) in TTI units. In addition, the definition of TTI is not limited to this.

[0431] TTI may also be a transmission time unit for a data packet (transport block), a code block, a code word, etc. that has been channel-coded, and may also be a processing unit for scheduling, link adaptation, etc. In addition, when TTI is given, the time interval (e.g., the number of symbols) to which a transport block, a code block, a code word, etc. is actually mapped may be shorter than the TTI.

[0432] In addition, when a time slot or a mini time slot is called TTI, one or more TTIs (i.e., one or more time slots or one or more mini time slots) can also be the minimum time unit of scheduling. In addition, the number of time slots (mini time slots) constituting the minimum time unit of scheduling can also be controlled.

[0433] A TTI having a time length of 1 ms may 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 may 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.

[0434] In addition, a long TTI (e.g., normal TTI, subframe, etc.) can also be rewritten as a TTI with a time length exceeding 1 ms, and a short TTI (e.g., shortened TTI, etc.) can also be rewritten as a TTI with a TTI length shorter than that of the long TTI and longer than 1 ms.

[0435] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers (subcarriers) in the frequency domain. The number of subcarriers included in an RB may also be the same regardless of the parameter set, for example, 12. The number of subcarriers included in an RB may also be determined based on the parameter set.

[0436] In addition, an RB may also include one or more symbols in the time domain, and may also be the length of a slot, a mini-slot, a subframe, or a TTI. A TTI, a subframe, etc. may also be composed of one or more resource blocks, respectively.

[0437] In addition, one or more RBs may also be referred to as a physical resource block (Physical RB (PRB)), a sub-carrier group (Sub-Carrier Group (SCG)), a resource element group (Resource Element Group (REG)), a PRB pair, an RB pair, etc.

[0438] In addition, a resource block may be composed of one or more resource elements (RE). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0439] A Bandwidth Part (BWP) (also referred to as a partial bandwidth, etc.) may also represent a subset of contiguous common RBs (common resource blocks) for a parameter set in a carrier. Here, a common RB may also be identified by an index of the RB relative to a common reference point of the carrier. PRBs may also be defined in a BWP and numbered within the BWP.

[0440] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). For a UE, one or more BWPs may be configured in one carrier.

[0441] At least one of the set BWPs may be activated, and the UE may not assume that it will transmit or receive a specific signal / channel other than the activated BWP. In addition, "cell", "carrier", etc. in the present disclosure may also be rewritten as "BWP".

[0442] In addition, the above-mentioned structures such as radio frames, subframes, time slots, mini-time slots and symbols are only examples. For example, the number of subframes included in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots included in a time slot, the number of symbols and RBs included in a time slot or mini-time slot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, and the cyclic prefix (CP) length can be changed in various ways.

Furthermore, the mathematical formulas, etc. using these parameters may be different from those explicitly disclosed in the present disclosure. Various channels (PUCCH, PDCCH, etc.) and information elements can be identified by any suitable names, and therefore, the various names assigned to these various channels and information elements are not restrictive in all respects.

[0445] Information, signals, etc. described in this disclosure may also be represented using any of a variety of different techniques. For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be mentioned throughout the above description may also be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or photons, or any combination thereof.

[0446] Furthermore, information, signals, etc. can be output in at least one of the following directions: from a higher layer (upper layer) to a lower layer (lower layer), and from a lower layer to a higher layer. Information, signals, etc. can also be input and output via multiple network nodes.

[0447] The input and output information, signals, etc. may be stored in a specific location (e.g., a memory), or may be managed using a management table. The input and output information, signals, etc. may be overwritten, updated, or appended. The output information, signals, etc. may also be deleted. The input information, signals, etc. may also be sent to other devices.

[0448] The notification of information is not limited to the methods / implementations described in the present disclosure, and may also be performed by other methods. For example, the notification of information in the present disclosure may also be implemented through physical layer signaling (e.g., downlink control information (Downlink Control Information (DCI))), uplink control information (Uplink Control Information (UCI))), high-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 a combination thereof.

[0449] In addition, physical layer signaling may also be referred to as layer 1 / layer 2 (Layer 1 / Layer 2 (L1 / L2)) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. In addition, RRC signaling may also be referred to as an RRC message, such as an RRC connection establishment (RRC Connection Setup) message, an RRC connection reconstruction (RRC Connection Reconfiguration) message, etc. In addition, MAC signaling may also be notified using, for example, a MAC control element (MACControl Element (CE)).

[0450] Furthermore, notification of specific information (eg, notification of “it is X”) is not limited to explicit notification, but may be performed implicitly (eg, by not notifying the specific information or by notifying other information).

[0451] The determination can be made by a value represented by a bit (0 or 1), by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a specific value).

[0452] Whether software is called software, firmware, middle-ware, microcode, hardware description language, or other names, it should be broadly interpreted as meaning instructions, instruction sets, code, code segments, program code, program, sub-program, software modules, applications, software applications, software packages, routines, sub-routines, objects, executable files, execution threads, procedures, functions, etc.

[0453] In addition, software, instructions, information, etc. may 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 technology (coaxial cable, fiber optic cable, twisted pair, Digital Subscriber Line (DSL), etc.) and wireless technology (infrared, microwave, etc.), at least one of these wired technology and wireless technology is included in the definition of transmission medium.

For example, for the methods described in this disclosure, the elements of various steps are presented in an illustrative order, but are not limited to the specific order presented.

[0479] The various modes / implementations described in the present disclosure may also be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), xth generation mobile communication system (xG (x is, for example, an integer or a decimal)), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), systems using other appropriate wireless communication methods, and next-generation systems based on these enhancements, corrections, generation or regulations, etc. In addition, multiple systems can also be applied in combination (for example, LTE or LTE-A, combination with 5G, etc.).

[0480] The phrase “based on” used in the present disclosure does not mean “based only on” unless otherwise specified. In other words, the phrase “based on” means both “based only on” and “based at least on”.

[0481] Any reference to an element using the terms "first", "second", etc. used in this disclosure does not fully define the amount or order of these elements. These terms can be used in this disclosure as a convenient method to distinguish between two or more elements. Therefore, reference to the first and second elements does not mean that only two elements can be used or that the first element must take precedence over the second element in some form.

[0482] The term "determining" used in the present disclosure may include a variety of actions. For example, "determining" may also refer to situations where judging, calculating, computing, processing, deriving, investigating, looking up (e.g., searching in a table, database or other data structure), ascertaining, etc. are considered to be "determining".

[0483] In addition, "judgment (decision)" may also be a situation where receiving (for example, receiving information), sending (for example, sending information), input (input), output (output), accessing (for example, accessing data in a memory), etc. are regarded as making a "judgment (decision)".

[0484] In addition, "judgment (decision)" can also be regarded as a situation where resolving, selecting, choosing, establishing, comparing, etc. are regarded as a situation where "judgment (decision)" is performed. That is, "judgment (decision)" can also be regarded as a situation where some actions are regarded as a situation where "judgment (decision)" is performed.

[0485] In addition, "judge (decide)" can also be rewritten as "assuming (assuming)", "expecting (expecting)", "considering (considering)" and so on.

[0486] The terms "connected", "coupled", or all their variations used in this disclosure refer to all direct or indirect connections or combinations between two or more elements, and may include the situation where one or more intermediate elements exist between two elements that are "connected" or "coupled" to each other. The combination or connection between elements may be physical, logical, or a combination thereof. For example, "connection" may also be rewritten as "access".

[0487] In the present disclosure, when two elements are connected, it is possible to consider being "connected" or "combined" to each other using one or more wires, cables, printed electrical connections, etc., as well as using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, light (both visible and invisible) region, etc. as several non-limiting and non-inclusive examples.

[0488] In the present disclosure, the term "A is different from B" may also mean "A and B are different from each other". In addition, the term may also mean "A and B are different from C, respectively". The terms "separate" and "combined" may also be interpreted in the same manner as "different".

[0489] When the terms “include,” “including,” and variations thereof are used in the present disclosure, these terms have an inclusive meaning, similar to the term “comprising.” Furthermore, the term “or” used in the present disclosure does not have an exclusive OR meaning.

[0490] In the present disclosure, when an article is added by translation like a, an, and the in English, for example, the present disclosure may also include a case where the noun following the article is in plural form.

[0491] The invention involved in the present disclosure has been described in detail above, but it is obvious to those skilled in the art that the invention involved in the present disclosure is not limited to the embodiments described in the present disclosure. The invention involved in the present disclosure can be implemented as a modified and altered mode without departing from the gist and scope of the invention determined based on the description of the claims. Therefore, the description of the present disclosure is for the purpose of illustrative description and does not have any limiting meaning on the invention involved in the present disclosure.
