Description

Terminal, wireless communication method and base station

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

[0002] Long Term Evolution (LTE) has been specified for the Universal Mobile Telecommunications System (UMTS) network with the aim of achieving higher data rates and lower latency (Non-Patent Document 1). Also, LTE-Advanced (3GPP Rel. 10-14) has been specified with the aim of achieving higher capacity and more advanced features than LTE (Third Generation Partnership Project (3GPP) Release (Rel.) 8, 9).

[0003] Successor systems to LTE (e.g., 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 or later, etc.) are also being considered.

[0004] 3GPP TS 36.300 V8.12.0 “Evolved Universal Terrestrial Radio Access (E-UTRA) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN); Overall description; Stage 2 (Release 8)”, April 2010

[0005] In future wireless communication systems, a UE will be able to use one of multiple panels (or multiple beams) for uplink (UL) transmission. Furthermore, in Rel. 18 and beyond, support for simultaneous UL transmission (e.g., simultaneous multi-panel UL transmission (SiMPUL)) using multiple panels to one or more Transmission / Reception Points (TRPs) is being considered to improve UL throughput / reliability.

[0006] However, there has been insufficient consideration on how to control UL transmission using multiple panels (e.g., simultaneous UL transmission). If UL transmission using multiple panels is not performed appropriately, there is a risk of degradation of system performance, such as a decrease in throughput.

[0007] Therefore, one of the objectives 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 multiple panels.

[0008] A terminal according to one aspect of the present disclosure includes a receiving unit that receives first configuration information regarding channel state information (CSI), second configuration information regarding a hybrid automatic repeat request acknowledgement (HARQ-ACK) or a scheduling request (SR), and third configuration information regarding simultaneous transmission of a physical uplink control channel (PUCCH) using multiple panels, and a control unit that determines a PUCCH resource to which the CSI and the HARQ-ACK or the SR in the same time domain are mapped based on the first configuration information, the second configuration information, and the third information.

[0009] According to one aspect of the present disclosure, even when UL transmission is performed using multiple panels, UL transmission can be appropriately controlled.

[0011] (PUCCH Format) In NR, a configuration (format, also referred to as PUCCH format (PF)) for an uplink control channel (e.g., PUCCH) is used to transmit uplink control information (UCI). For example, Rel. 15 NR supports PF0 to PF4 as shown in Figures 1A to 1E. Note that in Rel. 17 and later, the names of the PFs shown below are merely examples, and different names may be used.

[0012] For example, PF0 and 1 are PFs used for transmitting UCI of 2 bits or less (up to 2 bits). For example, the UCI may be at least one of delivery confirmation information (also referred to as Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK), acknowledgement (ACK) or negative-acknowledgement (NACK) or the like) and a scheduling request (scheduling request (SR)). PF0 can be allocated to 1 or 2 symbols, and is therefore also referred to as a short PUCCH. On the other hand, PF1 can be allocated to 4 to 14 symbols, and is therefore also referred to as a long PUCCH or the like. PF0 is also referred to as a sequence-based PUCCH because it uses a cyclic shift (CS) that depends on the value of the UCI and transmits a sequence obtained by cyclic shifting a base sequence. In PF1, multiple user terminals may be code division multiplexed (CDM) within the same physical resource block (PRB) using time domain block spreading using at least one of CS and time domain (TD)-orthogonal cover code (OCC). PF0 and PF1 may be mapped to one PRB.

[0013] PF2-PF4 are PFs used to transmit UCI of 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 symbols, and is therefore also referred to as short PUCCH, etc. PF3 and PF4 can be allocated to 4-14 symbols, and are therefore also referred to as long PUCCH, etc. PF4 allows multiple user terminals to perform CDM using block spreading in the frequency domain (FD)-OCC before DFT. PF2 and PF3 may be mapped to 1-16 PRBs. PF4 may be mapped to 1 PRB.

[0014] PF1-4 are also called DMRS-based PUCCHs because they transmit UCI and DMRS in resource blocks allocated to PUCCH. In PF1, PF3, and PF4, UCI and DMRS are time-division multiplexed (TDM). In PF2, DMRS is mapped to every three subcarriers, and UCI and DMRS are frequency-division multiplexed (FDM).

[0015] Intra-slot frequency hopping may be applied to PF1, PF3, and PF4. symb Then, the length before frequency hopping (first hop) is floor(N symb / 2), and the length after frequency hopping (second hop) is ceil(N symb / 2).

[0016] The waveforms of PF0, PF1, and PF2 may be Cyclic Prefix (CP)-Orthogonal Frequency Division Multiplexing (OFDM), and the waveforms of PF3 and PF4 may be Discrete Fourier Transform (DFT)-spread(s)-OFDM.

[0017] The allocation of resources (for example, PUCCH resources) used for transmitting the uplink control channel is performed using higher layer signaling and / or downlink control information (DCI).

[0018] Specifically, one or more sets (PUCCH resource sets), each including one or more PUCCH resources, are notified (configured) to a UE by higher layer signaling. For example, a network (e.g., a base station) may notify a user terminal of K (e.g., 1≦K≦4) PUCCH resource sets. Each PUCCH resource set may include M (e.g., 1≦M≦32) PUCCH resources.

[0019] The UE may determine a single PUCCH resource set (first PUCCH resource set) from the configured K PUCCH resource sets based on a payload size of the UCI (UCI payload size, number of UCI information bits). The UCI payload size may be the number of UCI bits excluding Cyclic Redundancy Check (CRC) bits.

[0020] The UE may determine a PUCCH resource to be used for transmitting UCI from the M PUCCH resources included in the determined PUCCH resource set based on at least one of DCI and implicit information (also referred to as implicit indication information or implicit index, etc.). For example, the implicit indication information may be a first CCE index for receiving a PDCCH carrying the DCI.

[0021] Each PUCCH resource configured for a UE may include a value of at least one of the following parameters (also referred to as a field or information, etc.): Note that a range of values ​​that each parameter can take may be defined for each PUCCH format. Symbol at which PUCCH allocation starts (start symbol) Number of symbols allocated to PUCCH within a slot (duration allocated to PUCCH) Index of resource block (physical resource block (PRB)) at which PUCCH allocation starts Number of PRBs allocated to PUCCH Whether frequency hopping is enabled for PUCCH Second hop frequency resource and initial cyclic shift (CS) index when frequency hopping is enabled Index of orthogonal spreading code (for example, OCC: Orthogonal Cover Code) in the time domain, and length of OCC used for block spreading before discrete Fourier transform (DFT) (also referred to as OCC length, spreading factor, etc.) Index of OCC used for block-wise spreading after DFT

[0022] A low-power to average power ratio (low PAPR) sequence is used for the UCI in PF0 / PF1 and the DMRS in PF1 / PF3 / PF4. A pseudo-random sequence (Gold sequence) is used for the DMRS in PF2.

[0023] (Simultaneous multi-panel UL transmission (SiMPUL)) In future wireless communication systems (e.g., Rel. 18 and later), support for simultaneous UL transmission using multiple panels (e.g., simultaneous multi-panel UL transmission (SiMPUL)) to one or more transmission / reception points (TRPs) is being considered to improve UL throughput / reliability.

[0024] In simultaneous UL transmission using multiple panels, the UE may transmit multiple physical uplink control channels (PUCCHs).

[0025] In the following description of the present disclosure, an example in which the number of panels is two will be described, but the number of panels may be three or more. In other words, the number of panels, which is two, may be interpreted as three or more.

[0026] As transmission methods for simultaneous UL transmission using multiple panels for PUCCH, the following schemes 1 and 2 are being considered.

[0027] Scheme 1: Two PUCCH resources overlap in the time domain and are transmitted simultaneously. Each of the two PUCCH resources is associated with a different panel / beam (see Fig. 2A). Each of the two beams is transmitted towards a respective TRP.

[0028] Scheme 2: One PUCCH resource is transmitted simultaneously using two panel / spatial relationships. One PUCCH resource is associated with two panels / beams (see Fig. 2B). Each of the two beams is transmitted towards a respective TRP.

[0029] Note that scheme 2 may be applied to repetitive transmission of PUCCH in a single frequency network (SFN).

[0030] Up to Rel. 17, when two PUCCH / PUSCH transmissions with different priorities are transmitted, the UE first de-overlaps the PUCCH / PUSCH transmission with the smaller (lower) priority index.

[0031] If multiplexing of UCIs of different priorities is supported, firstly, the UE eliminates overlapping PUCCH / PUSCH transmissions of larger (higher) priority indexes.

[0032] Second, the UE de-duplicates PUCCH transmissions of different priority indices.

[0033] Third, the UE eliminates overlaps between PUCCH and PUSCH transmissions of different priority indices.

[0034] If multiplexing of UCIs with different priorities is not supported, the UE cancels / drops the PUCCH / PUSCH with a lower priority index according to rules predefined in the specifications.

[0035] However, when simultaneous transmission using multiple panels for multiple PUCCHs (e.g., PUCCH / UCIs with different priorities) is supported, the UE behavior regarding overlapping PUCCH transmissions is unclear, which may result in reduced system performance, such as reduced throughput.

[0036] Therefore, the present inventors have conceived a method for appropriately controlling UL transmission even when UL transmission is performed using multiple panels.

[0037] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the drawings. Wireless communication methods according to the embodiments may be applied independently or in combination.

In other words, the PUCCH formats of the present disclosure may be expressed by the functions / features of the PUCCH formats described above.

[0050] Furthermore, although CSI, HARQ-ACK, and SR are described as UCI in this disclosure, these terms may be interchanged as appropriate.

[0051] (Wireless Communication Method) PUCCH resources for UCI (eg, SR / HARQ-ACK / CSI) and panels may be associated based on a specific method.

[0052] The association may be configured in the UE using higher layer signaling (e.g., RRC / MAC CE), may be indicated to the UE using DCI, or may be notified to the UE using a combination of RRC / MAC CE / DCI.

[0053] The panels may be associated with PUCCH resources or with spatial relationship information / TCI status of the PUCCH resources.

[0054] The UCI (eg, SR / HARQ-ACK / CSI report) and the panel may be associated based on a specific method.

[0055] The association may be configured in the UE using higher layer signaling (e.g., RRC / MAC CE), may be indicated to the UE using DCI, or may be notified to the UE using a combination of RRC / MAC CE / DCI.

[0056] The panel may be associated with a PUCCH resource of the UCI, or may be associated with at least one of a CSI reporting configuration, an SR configuration, and a PDCCH / PDSCH corresponding to HARQ-ACK information.

[0057] Each embodiment / aspect / option / choice in the present disclosure may be applied to the use of at least one of a single DCI using multiple TRPs and multiple DCIs using multiple TRPs.

[0058] In the following embodiments and drawings of the present disclosure, cases where PUCCH / CSI / HARQ-ACK / SR overlap in the time domain will be described. This overlap may mean that the PUCCH resources completely overlap, that at least some of the PUCCH resources overlap, or that the time resource of one PUCCH resource is completely included in the time resource of another PUCCH resource.

[0059] The following embodiments of the present disclosure may be used when the above scheme 1 / 2 is applied.

[0060] First Embodiment (Analysis 1) Up to Rel. 16 / 17, a UE may transmit up to two PUCCH resources in one slot.

[0061] If the HARQ-ACK feedback mode is not set to separate (for example, when the RRC parameter ackNackFeedbackMode=separate is not satisfied), at least one of the two PUCCH resources in one slot is PUCCH format 0 or 2.

[0062] These limitations arise from the fact that there is no use case in which two long PUCCHs (e.g., a 7-symbol PUCCH and a 7-symbol PUCCH) are time-division multiplexed (TDM) in one slot in the PUCCH of Rel. 15.

[0063] However, it is unclear whether these restrictions apply when simultaneous transmission using multiple panels for multiple PUCCHs (eg, PUCCH / UCIs of different priorities) is supported.

[0064] In the first embodiment, the number of PUCCHs (resources) that a UE can transmit will be described below.

[0065] When a UE supports simultaneous multi-panel transmission of PUCCH, the number of PUCCHs that the UE may transmit in one slot in a CC (cell) may follow at least one of the following options 1-0 and 1-1.

[0066] <<Option 1-0>> The UE may transmit up to M PUCCHs (M is a specific integer, e.g., 2) in one slot in a CC (cell) across multiple (e.g., all) panels.

[0067] In this case, at least one of the multiple (e.g., two) PUCCHs may be restricted to a specific PUCCH format. For example, the specific PUCCH format may be a PUCCH format with a relatively short number of symbols (e.g., PUCCH format 0 / 2, short PUCCH).

[0068] This restriction on the PUCCH format may be applied only when a specific higher layer parameter is not set to a specific condition (for example, when the RRC parameter ackNackFeedbackMode=separate is not satisfied).

[0069] <<Option 1-1>> The UE may transmit a total of N (N is an integer) PUCCHs in one slot in a certain CC (cell).

[0070] The N may be an integer greater than two.

[0071] For example, when PUCCH (simultaneous) transmission is performed in two panels, N may be 2×M (M is a specific integer, for example, 2). Also, when PUCCH (simultaneous) transmission is performed in X panels, N may be X×M.

[0072] A UE may transmit up to two PUCCHs in different symbols within one slot in a CC (cell) for PUCCHs associated with the same panel.

[0073] At least one of two PUCCHs associated with the same panel in one slot may be a specific PUCCH format, for example, a PUCCH format with a relatively short number of symbols (e.g., PUCCH format 0 / 2, short PUCCH).

[0074] This restriction on the PUCCH format may be applied, for example, only when multi-DCI using multi-TRP is configured and specific upper layer parameters are not set to specific conditions (for example, when the RRC parameter ackNackFeedbackMode=separate is not set).

[0075] 3 is a diagram showing an example of the number of PUCCHs according to Option 1-1. In the example shown in Fig. 3, the UE transmits a total of four PUCCHs (PUCCHs #1-#4) across two panels in one slot.

[0076] In the example shown in Figure 3, up to two PUCCHs are associated with one panel within one slot. Here, PUCCHs #1 and #2 are associated with panel #1, and PUCCHs #3 and #4 are associated with panel #2. PUCCHs corresponding to the same panel are hatched with the same color. Hereinafter, in the diagrams showing associations related to PUCCHs / UCIs, PUCCHs / UCIs with the same color hatching may mean that they are associated with the same panel.

[0077] According to the first embodiment described above, even when simultaneous transmission using multiple panels is applied, the maximum number of PUCCHs in one slot can be appropriately determined.

[0078] Second Embodiment (Analysis 2) In Rel. 16 / 17, if a UE is configured with PUCCH resources for multiple CSIs in one slot and the RRC parameter for multiple PUCCH resource lists for CSIs (multi-CSI-PUCCH-ResourceList) is not configured, the UE determines two PUCCH resources in one slot according to the priority of the CSI reports.

[0079] In this case, first, the UE determines the PUCCH resource (first resource) corresponding to the CSI report with the highest (highest) priority.

[0080] Second, the UE determines a PUCCH resource (second resource) corresponding to a CSI report with the highest priority among CSI reports corresponding to remaining resources excluding the first resource.

[0081] When the first resource is PUCCH format 2, the remaining resources excluding the first resource are resources that do not overlap with the first resource within the slot.

[0082] If the first resource is PUCCH format 3 or 4, the remaining resources excluding the first resource are PUCCH format 2 resources that do not overlap with the first resource within the slot.

[0083] In Rel. 16 / 17, if a UE is configured with PUCCH resources for multiple CSI in one slot and the RRC parameter for multiple PUCCH resource lists for CSI (multi-CSI-PUCCH-ResourceList) is configured, the UE multiplexes all CSI reports in one resource.

[0084] However, when simultaneous transmission using multiple panels for multiple PUCCHs is supported, it is unclear how the UE should behave when multiple PUCCH resources associated with multiple panels for CSI are configured within one slot.

[0085] In the second embodiment, simultaneous transmission using multiple panels for PUCCHs for multiple CSIs will be described below.

[0086] The UE may support simultaneous multi-panel transmission of the PUCCH. The simultaneous multi-panel transmission of the PUCCH may be configured for the UE. The configuration may be performed using specific higher layer parameters.

[0087] If the UE is configured with multiple PUCCH resources for CSI within one slot and multiple (e.g., two) PUCCHs for multiple (e.g., two) CSI reports are associated with the same panel, the UE may follow at least one of options 2-A-1 to 2-A-3 described below.

[0088] The UE may multiplex / map multiple (e.g., two) CSI reports associated with the same panel in one PUCCH (option 2-A-1).

[0089] The UE may not multiplex / map multiple (e.g., two) CSI reports associated with the same panel in one PUCCH (option 2-A-2).

[0090] The UE may be configured to apply either of the above options 2-A-1 and 2-A-2 using higher layer signaling (RRC / MAC CE) (option 2-A-3).

[0091] In option 2-A-3, the setting may be made for each panel.

[0092] If the UE is configured with multiple PUCCH resources for CSI within one slot and the multiple (e.g., two) PUCCHs for the multiple (e.g., two) CSI reports are associated with different panels, the UE may follow at least one of options 2-B-1 to 2-B-3 described below.

[0093] The UE may multiplex / map multiple (e.g., two) CSI reports associated with different panels in one PUCCH (option 2-B-1).

[0094] The UE may not multiplex / map multiple (e.g., two) CSI reports associated with different panels in one PUCCH (option 2-B-2).

[0095] The UE may be configured to apply either of the above options 2-B-1 and 2-B-2 using higher layer signaling (RRC / MAC CE) (option 2-B-3).

[0096] In option 2-B-3, the setting may be made for each panel / panel pair.

[0097] <<Aspect 2-1>> The UE may support simultaneous multi-panel transmission of the PUCCH.

[0098] A UE may be configured with multiple PUCCH resources for CSI within one slot.

[0099] This aspect may be applied, for example, in a combination of the above options 2-A-1 and 2-B-1.

[0100] The UE may follow the behavior specified in existing specifications (e.g., Rel. 16).

[0101] For example, the UE may determine one PUCCH resource from RRC parameters related to multiple PUCCH resource lists for CSI (e.g., multi-CSI-PUCCH-ResourceList) according to a specific rule, and may multiplex / map multiple (e.g., all) CSIs in the determined one PUCCH resource.

[0102] 4 is a diagram illustrating an example of CSI multiplexing / mapping according to aspect 2-1. In the example shown in FIG. 4, four CSI reports (CSI #1-#4) are configured for a UE within one slot. PUCCH resources corresponding to CSI #1 and #2 are associated with one panel (panel #1), and PUCCH resources corresponding to CSI #1 and #2 are associated with another panel (panel #2).

[0103] In the example shown in FIG. 4, the UE multiplexes / maps and transmits CSI#1-#4 in one resource.

[0104] <<Aspect 2-2>> The UE may support simultaneous multi-panel transmission of the PUCCH.

[0105] A UE may be configured with multiple PUCCH resources for CSI within one slot.

[0106] This aspect may be applied, for example, in a combination of Options 2-A-2 and 2-B-2 above.

[0107] The UE may follow at least one of the following options 2-2-0 and 2-2-1.

[0108] [Option 2-2-0] The UE may determine multiple (eg, two) PUCCH resources for CSI reporting across multiple (eg, all) panels.

[0109] The UE may determine a PUCCH resource (first resource) corresponding to the CSI report with the highest (maximum) priority among the CSI reports associated with any panel.

[0110] The UE may determine a PUCCH resource (second resource) corresponding to a CSI report with the highest priority among CSI reports corresponding to remaining resources excluding the first resource, which are associated with any panel.

[0111] When the first resource is a first PUCCH format (e.g., a relatively short PUCCH format, a short PUCCH, or PUCCH format 2), the remaining resources excluding the first resource may be resources that do not overlap with the first resource within a slot. In this case, the remaining resources may be associated with any panel.

[0112] When the first resource is a second PUCCH format (a relatively long PUCCH format, a long PUCCH, or PUCCH format 3 / 4), the remaining resources excluding the first resource may be resources of the first PUCCH format that do not overlap with the first resource within the slot, and the remaining resources may be associated with any panel.

[0113] Resources other than the first and second resources may be dropped.

[0114] 5A is a diagram showing an example of association of CSI and PUCCH resources according to Option 2-2-0. In the example shown in FIG. 5A, four CSI reports (CSI #1-#4) are configured within one slot. PUCCH resources corresponding to CSI #1 and #2 are associated with one panel (panel #1), and 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.

[0115] In the example shown in Figure 5A, the UE determines the PUCCH resource corresponding to the highest priority CSI #1 across all panels (panels #1 and #2) as the first resource. The UE determines the PUCCH resource corresponding to the highest priority CSI #2 across all panels (panels #1 and #2) for the remaining CSIs excluding the CSI corresponding to the first resource as the second resource. In this case, CSI #3 and #4 are dropped.

[0116] [Option 2-2-1] For each panel, the UE may determine multiple (eg, two) PUCCH resources within one slot for CSI reporting.

[0117] For each panel, the UE may determine a PUCCH resource (first resource) corresponding to the CSI report with the highest (highest) priority among the CSI reports associated with the panel.

[0118] For each panel, the UE may determine a PUCCH resource (second resource) corresponding to a CSI report with the highest priority among the CSI reports corresponding to the remaining resources associated with the panel, excluding the first resource.

[0119] When the first resource is a first PUCCH format (e.g., a relatively short PUCCH format, a short PUCCH, or PUCCH format 2), the remaining resources other than the first resource may be resources that do not overlap with the first resource within a slot, and in this case, the remaining resources may be associated with the same panel.

[0120] If the first resource is a second PUCCH format (a relatively long PUCCH format, a long PUCCH, or PUCCH format 3 / 4), the remaining resources excluding the first resource may be resources of the first PUCCH format that do not overlap with the first resource within the slot, and the remaining resources may be associated with the same panel.

[0121] For each panel, resources other than the first and second resources may be dropped.

[0122] 5B is a diagram showing an example of association of CSI and PUCCH resources according to Option 2-2-1. In the example shown in FIG. 5B, four CSI reports (CSI #1-#4) are configured within one slot. PUCCH resources corresponding to CSI #1 and #2 are associated with one panel (panel #1), and 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.

[0123] In the example shown in Figure 5B, the UE determines the PUCCH resource corresponding to the highest priority CSI #1 as the first resource in panel #1, and determines the PUCCH resource corresponding to the highest priority CSI #2 as the second resource for the remaining CSIs excluding the CSI corresponding to the first resource in panel #1.

[0124] In the example shown in Figure 5B, the UE determines the PUCCH resource corresponding to the highest priority CSI #3 as the first resource in panel #2, and determines the PUCCH resource corresponding to the highest priority CSI #4 as the second resource for the remaining CSIs other than the CSI corresponding to the first resource in panel #2.

[0125] <<Aspect 2-3>> The UE may support simultaneous multi-panel transmission of the PUCCH.

[0126] A UE may be configured with multiple PUCCH resources for CSI within one slot.

[0127] This aspect may be applied, for example, in a combination of the above options 2-A-1 and 2-B-2.

[0128] For each panel, the UE may multiplex / map multiple (eg, all) CSI reports associated with the same panel in one resource.

[0129] For each panel, the one resource may be determined according to a specific rule from an RRC parameter related to a PUCCH resource list for CSI (e.g., multi-CSI-PUCCH-ResourceList) associated with the panel, and the UE may follow at least one of the following variations 2-3-1 and 2-3-2.

[0130] [Variation 2-3-1] A single resource list may be configured for the UE. The single resource list may include resources across multiple (e.g., all) panels. For each panel, the single resource may be determined from the resources associated with that panel in the list.

[0131] [Variation 2-3-2] For each panel, a list of resources may be configured for the UE, and for each panel, the resource may be determined from a resource list associated with the panel.

[0132] In aspect 2-3, the UE may simultaneously transmit multiple (e.g., two) PUCCH resources associated with multiple (e.g., two) panels, each of which may include one or more CSIs associated with the same panel.

[0133] 6 is a diagram showing an example of association of CSI and PUCCH resources according to aspect 2-3. In the example shown in FIG. 6, four CSI reports (CSI #1-#4) are configured in one slot. PUCCH resources corresponding to CSI #1 and #2 are associated with one panel (panel #1), and PUCCH resources corresponding to CSI #1 and #2 are associated with another panel (panel #2).

[0134] In the example shown in Figure 6, the UE multiplexes / maps CSI #1 and #2 in resources associated with panel #1, and CSI #3 and #4 in resources associated with panel #2, which are determined from a list of resources based on a specific rule.

[0135] According to the second embodiment described above, even if multiple pieces of CSI overlap when simultaneous transmission using multiple panels of PUCCH is performed, the multiple pieces of CSI can be transmitted appropriately.

[0136] <Third Embodiment> (Analysis 3) In Rel. 16 / 17, except when a UE is configured with multiple DCIs using multiple TRPs and the HARQ-ACK feedback mode is set to separate (e.g., when the RRC parameter ackNackFeedbackMode=separate) (which may be referred to as Case 1), for multiple PUCCH resources including HARQ-ACK information indicated in the same slot, the UE multiplexes / maps all the HARQ-ACK information in one PUCCH resource.

[0137] In Rel. 16 / 17, when a UE is configured with multiple DCIs using multiple TRPs and the HARQ-ACK feedback mode is set to separate (also referred to as Case 2), for multiple PUCCH resources containing HARQ-ACK information indicated in the same slot, the UE multiplexes / maps HARQ-ACK information associated with the same CORESET pool index (coresetPoolIndex) in one PUCCH resource for each CORESET pool index. In this case, 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.

[0138] However, when simultaneous transmission using multiple panels for multiple PUCCHs is supported and corresponds to the above cases 1 / 2, it is unclear what the UE's behavior is regarding PUCCH resources for HARQ-ACK information.

[0139] In the third embodiment, simultaneous transmission using multiple panels for PUCCH for multiple HARQ-ACKs will be described below.

[0140] The UE may support simultaneous multi-panel transmission of the PUCCH. The simultaneous multi-panel transmission of the PUCCH may be configured for the UE. The configuration may be performed using specific higher layer parameters.

[0141] This embodiment may be applied, for example, when a UE is configured with multiple DCIs using multiple TRPs and specific upper layer parameters are set to specific conditions (for example, when the RRC parameter ackNackFeedbackMode = separate).

[0142] For multiple PUCCH resources containing HARQ-ACK information indicated in the same slot, the UE may multiplex / map the HARQ-ACK information associated with the same CORESET pool index in one PUCCH resource for each CORESET pool index (coresetPoolIndex).

[0143] The UE may multiplex / map different HARQ-ACK information corresponding to different CORESET pool indices in different PUCCH resources, respectively.

[0144] The UE may make an assumption as to whether the PUCCH resources (multiple PUCCH resources) corresponding to each of multiple HARQ-ACK information indicated in the same slot overlap in the time domain based on whether the PUCCH resources are associated with the same CORESET pool index.

[0145] The UE may follow at least one of the following options 3-0 and 3-1.

[0146] <<Option 3-0>> The UE may not expect / assume that multiple (e.g., two) PUCCH resources associated with different CORESET pool indices (coresetPoolIndex) overlap (in the time domain), regardless of whether the multiple (e.g., two) PUCCH resources are associated with the same panel or different panels.

[0147] <<Option 3-1>> If 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 does not need to expect / assume that the multiple PUCCH resources overlap (in the time domain).

[0148] If each of the PUCCH resources (multiple PUCCH resources) corresponding to each of multiple (e.g., two) CORESET pool indices is associated with a different panel, the UE may follow at least one of the following options 3-1-1 to 3-1-3.

[0149] [Option 3-1-1] The UE may not expect / assume that the PUCCH resources associated with different panels (multiple PUCCH resources) overlap (in the time domain).

[0150] [Option 3-1-2] The UE may expect / assume that PUCCH resources associated with different panels (multiple PUCCH resources) overlap (in the time domain), and then the UE may transmit the multiple PUCCH resources simultaneously (overlapping in the time domain).

[0151] FIG. 7 is a diagram showing an example of association of multiple HARQ-ACKs with PUCCH resources according to option 3-1-2.

[0152] In the example shown in Figure 7, the UE is configured with two HARQ-ACKs (HARQ-ACK #1 and #2) / PUCCH associated with different CORESET pool indices corresponding to different panels. In the example shown in Figure 7, the UE transmits each HARQ-ACK on resources associated with the CORESET pool index / panel corresponding to the respective HARQ-ACK.

[0153] [Option 3-1-3] The UE may be configured to apply either option 3-1-1 or option 3-1-2 using higher layer signaling (RRC / MAC CE).

[0154] According to the third embodiment described above, even if multiple HARQ-ACKs overlap when simultaneous transmission is performed using multiple panels of PUCCH, the multiple HARQ-ACKs can be transmitted appropriately.

[0155] <Fourth Embodiment> (Analysis 4) In Rel. 16 / 17, if a PUCCH resource including a positive SR overlaps with a PUCCH resource using PUCCH format 0 including HARQ-ACK, the UE multiplexes / maps the SR and HARQ-ACK onto the resource for HARQ-ACK and transmits them.

[0156] In Rel. 16 / 17, if a PUCCH resource using PUCCH format 0 with SR overlaps with a PUCCH resource using PUCCH format 1 with HARQ-ACK, the UE drops the SR and transmits only the HARQ-ACK on the resource for HARQ-ACK.

[0157] In Rel. 16 / 17, if a PUCCH resource using PUCCH format 1 with a positive SR overlaps with a PUCCH resource using PUCCH format 1 with a HARQ-ACK, the UE maps the HARQ-ACK to the resource for SR and transmits it.

[0158] In Rel. 16 / 17, if a PUCCH resource using PUCCH format 1 with a negative SR overlaps with a PUCCH resource using PUCCH format 1 with a HARQ-ACK, the UE maps the HARQ-ACK to the resource for HARQ-ACK and transmits it.

[0159] In Rel. 16 / 17, if a PUCCH resource including an SR overlaps with a PUCCH resource using PUCCH format 2 / 3 / 4 including an HARQ-ACK, the UE multiplexes / maps the SR and HARQ-ACK onto the HARQ-ACK resource for transmission.

[0160] However, if simultaneous transmission using multiple panels for multiple PUCCHs is supported, it is unclear what the UE's transmission behavior is regarding PUCCH resources for SR and HARQ-ACK information.

[0161] In the fourth embodiment, simultaneous transmission using multiple panels for PUCCH for SR and HARQ-ACK will be described below.

[0162] The UE may support simultaneous multi-panel transmission of the PUCCH. The simultaneous multi-panel transmission of the PUCCH may be configured for the UE. The configuration may be performed using specific higher layer parameters.

[0163] The UE may determine the multiplexing / mapping of at least one of the HARQ-ACK and the SR based on at least one of whether the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with the same panel or different panels, and the PUCCH format corresponding to the PUCCH resource for SR and the PUCCH format corresponding to the PUCCH resource for HARQ-ACK.

[0164] Aspect 4-1: If a PUCCH resource including a positive SR and a PUCCH resource using a specific PUCCH format including HARQ-ACK (e.g., PUCCH format 0) overlap (in the time domain), the UE may follow at least one of options 4-1-0 and 4-1-1 below.

[0165] [Option 4-1-0] The UE may multiplex / map and transmit SR and HARQ-ACK in the PUCCH resource for HARQ-ACK, regardless of whether the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with the same panel or different panels.

[0166] [Option 4-1-1] When the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with the same panel, the UE may multiplex / map the SR and HARQ-ACK in the PUCCH resource for HARQ-ACK and transmit them.

[0167] If the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with different panels, the UE may follow at least one of the following options 4-1-1-1 to 4-1-1-3.

[0168] The UE may multiplex / map and transmit SR and HARQ-ACK in the PUCCH resource for HARQ-ACK (option 4-1-1-1).

[0169] The UE may not multiplex / map SR and HARQ-ACK on the same resource (option 4-1-1-2), in which case the UE may transmit SR on the PUCCH resource for SR and transmit HARQ-ACK on the PUCCH resource for HARQ-ACK.

[0170] The UE may be configured to apply either of the above options 4-1-1-1 and 4-1-1-2 using higher layer signaling (RRC / MAC CE) (option 4-1-1-3).

[0171] FIG. 8 is a diagram showing an example of association between SR / HARQ-ACK and PUCCH resources according to option 4-1-1-2.

[0172] In the example shown in Figure 8, the UE is configured with SR and HARQ-ACK corresponding to different panels. In the example shown in Figure 8, HARQ-ACK is associated with panel #1 and SR is associated with panel #2. In the example shown in Figure 8, the UE transmits HARQ-ACK on the PUCCH resource for HARQ-ACK (i.e., the PUCCH resource associated with panel #1) and transmits SR on the PUCCH resource for SR (i.e., the PUCCH resource associated with panel #2).

[0173] Aspect 4-2: If PUCCH resources including SR and PUCCH resources using a specific PUCCH format including HARQ-ACK (e.g., PUCCH format 2 / 3 / 4) overlap (in the time domain), the UE may follow at least one of the above-mentioned options 4-1-0 and 4-1-1.

[0174] Aspect 4-3: When PUCCH resources using a first PUCCH format (e.g., PUCCH format 0) including SR and PUCCH resources using a second PUCCH format (e.g., PUCCH format 1) including HARQ-ACK overlap (in the time domain), the UE may follow at least one of Options 4-3-0 and 4-3-1 below.

[0175] [Option 4-3-0] The UE may drop the SR and transmit HARQ-ACK (only HARQ-ACK) in the PUCCH resource for HARQ-ACK, regardless of whether the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with the same panel or different panels.

[0176] [Option 4-3-1] If the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with the same panel, the UE may drop the SR and transmit the HARQ-ACK (only the HARQ-ACK) in the PUCCH resource for HARQ-ACK.

[0177] If the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with different panels, the UE may follow at least one of the following options 4-3-1-1 to 4-3-1-3.

[0178] The UE may drop the SR and transmit HARQ-ACK (HARQ-ACK only) in the PUCCH resource for HARQ-ACK (option 4-3-1-1).

[0179] The UE may transmit the SR on the PUCCH resource for SR and transmit the HARQ-ACK on the PUCCH resource for HARQ-ACK (option 4-3-1-2).

[0180] The UE may be configured to apply either of the above options 4-3-1-1 and 4-3-1-2 using higher layer signaling (RRC / MAC CE) (option 4-3-1-3).

[0181] Aspect 4-4: When a PUCCH resource using a specific PUCCH format (e.g., PUCCH format 1) including a positive SR overlaps (in the time domain) with a PUCCH resource using a specific PUCCH format (e.g., PUCCH format 1) including a HARQ-ACK, the UE may follow at least one of Options 4-4-0 and 4-4-1 below.

[0182] [Option 4-4-0] The UE may transmit HARQ-ACK in the PUCCH resource for SR, regardless of whether the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with the same panel or different panels.

[0183] [Option 4-4-1] When the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with the same panel, the UE may transmit HARQ-ACK in the PUCCH resource for SR.

[0184] If the PUCCH resources for SR and the PUCCH resources for HARQ-ACK are associated with different panels, the UE may follow at least one of the following options 4-4-1-1 to 4-4-1-3.

[0185] The UE may transmit HARQ-ACK in the PUCCH resource for SR (option 4-4-1-1).

[0186] At this time, the UE may transmit the SR on the PUCCH resource for SR and transmit the HARQ-ACK on the PUCCH resource for HARQ-ACK (option 4-4-1-2).

[0187] The UE may be configured to apply either of the above options 4-4-1-1 and 4-4-1-2 using higher layer signaling (RRC / MAC CE) (option 4-4-1-3).

[0188] According to the fourth embodiment described above, even if HARQ-ACK and SR overlap when simultaneous transmission using multiple panels of PUCCH is performed, HARQ-ACK / SR can be transmitted appropriately.

[0189] Fifth Embodiment (Analysis 5) In Rel. 16 / 17, when a PUCCH resource including an SR overlaps with a PUCCH resource using PUCCH format 2 / 3 / 4 including CSI, the UE multiplexes / maps the SR and CSI into the resource for CSI and transmits the multiplexed SR and CSI.

[0190] However, if simultaneous transmission using multiple panels for multiple PUCCHs is supported, it is unclear about the UE transmission behavior regarding PUCCH resources for SR and CSI.

[0191] In the fifth embodiment, simultaneous transmission using multiple panels for PUCCH for SR and CSI will be described below.

[0192] The UE may support simultaneous multi-panel transmission of the PUCCH. The simultaneous multi-panel transmission of the PUCCH may be configured for the UE. The configuration may be performed using specific higher layer parameters.

[0193] If a PUCCH resource using a specific PUCCH format including SR overlaps (in the time domain) with a PUCCH resource using a specific PUCCH format including CSI (e.g., PUCCH format 2 / 3 / 4), the UE may follow at least one of options 5-0 and 5-1 below.

[0194] [Option 5-0] The UE may multiplex / map the SR and CSI to the resources for CSI and transmit them, regardless of whether the PUCCH resources for SR and the PUCCH resources for CSI are associated with the same panel or different panels.

[0195] [Option 5-1] The UE may determine the mapping of at least one of the PUCCH resource for the SR and the PUCCH resource for the CSI based on whether the SR and the PUCCH resource for the CSI are associated with the same panel.

[0196] When the PUCCH resource for SR and the PUCCH resource for CSI are associated with the same panel, the UE may multiplex / map the SR and CSI to the resource for CSI and transmit them.

[0197] If the PUCCH resource for SR and the PUCCH resource for HARQ-ACK are associated with different panels, the UE may follow at least one of the following options 5-1-1 to 5-1-3.

[0198] The UE may multiplex / map the SR and CSI to the resources for CSI and transmit them (option 5-1-1).

[0199] The UE may not multiplex / map the SR and CSI in the same resource (option 5-1-2), in which case the UE may transmit the CSI in the PUCCH resource for CSI and the SR in the PUCCH resource for SR.

[0200] The UE may be configured to apply either of the above options 5-1-1 and 5-1-2 using higher layer signaling (RRC / MAC CE) (option 5-1-3).

[0201] FIG. 9 is a diagram showing an example of association between SR / CSI and PUCCH resources according to option 5-1-2.

[0202] In the example shown in Figure 9, the UE is configured with SR and CSI corresponding to different panels. In the example shown in Figure 9, CSI is associated with panel #1 and SR is associated with panel #2. In the example shown in Figure 9, the UE transmits CSI in the PUCCH resource for CSI (i.e., the PUCCH resource associated with panel #1) and transmits SR in the PUCCH resource for SR (i.e., the PUCCH resource associated with panel #2).

[0203] According to the fifth embodiment described above, even if CSI and SR overlap when simultaneous transmission using multiple panels of PUCCH is performed, CSI / SR can be transmitted appropriately.

[0204] Sixth Embodiment (Analysis 6) In Rel. 16 / 17, when a PUCCH resource containing CSI overlaps with a PUCCH resource containing HARQ-ACK, if the RRC parameter for simultaneous transmission of HARQ-ACK and CSI ("simultaneousHARQ-ACK-CSI") is provided, the UE multiplexes / maps and transmits the HARQ-ACK and CSI on one PUCCH resource. If the RRC parameter for simultaneous transmission of HARQ-ACK and CSI ("simultaneousHARQ-ACK-CSI") is not provided, the UE drops the CSI and transmits the HARQ-ACK (only HARQ-ACK).

[0205] However, if simultaneous transmission using multiple panels for multiple PUCCHs is supported, it is unclear about the UE's transmission behavior regarding PUCCH resources for HARQ-ACK and CSI.

[0206] In the sixth embodiment, simultaneous transmission using multiple panels for PUCCH for SR and CSI will be described below.

[0207] The UE may support simultaneous multi-panel transmission of the PUCCH. The simultaneous multi-panel transmission of the PUCCH may be configured for the UE. The configuration may be performed using specific higher layer parameters.

[0208] The UE may determine the mapping of the HARQ-ACK and / or the CSI based on whether the PUCCH resource for the HARQ-ACK and the PUCCH resource for the CSI are associated with the same panel.

[0209] Example 6-1 Example 6-1 describes a case where a PUCCH resource including CSI overlaps with a PUCCH resource including HARQ-ACK, and the PUCCH resource for HARQ-ACK and the PUCCH resource for CSI are associated with the same panel.

[0210] In aspect 6-1, the UE may follow at least one of the following options 6-1-1 to 6-1-3.

[0211] The UE may multiplex / map CSI and HARQ-ACK onto one PUCCH resource and transmit them (option 6-1-1).

[0212] The UE may not multiplex / map CSI and HARQ-ACK in the same resource (option 6-1-2), in which case the UE may drop the CSI report and transmit HARQ-ACK in one PUCCH resource.

[0213] The UE may be configured to apply either of the above options 6-1-1 and 6-1-2 using higher layer signaling (RRC / MAC CE) (option 6-1-3).

[0214] Example 6-2 Example 6-2 describes a case where a PUCCH resource including CSI overlaps with a PUCCH resource including HARQ-ACK, and the PUCCH resource for SR and the PUCCH resource for CSI are associated with different panels.

[0215] In aspect 6-2, the UE may follow at least one of the following options 6-2-1 to 6-2-3.

[0216] The UE may multiplex / map CSI and HARQ-ACK onto one PUCCH resource and transmit them (option 6-2-1).

[0217] The UE may not multiplex / map the CSI and the HARQ-ACK in the same resource (option 6-2-2). In this case, the UE may transmit the CSI in the PUCCH resource for CSI and the HARQ-ACK in the PUCCH resource for HARQ-ACK.

[0218] The UE may be configured to apply either of the above options 6-2-1 and 6-2-2 using higher layer signaling (RRC / MAC CE) (option 6-2-3).

[0219] The above options 6-1-1 / 6-1-2 / 6-1-3 / 6-2-1 / 6-2-2 / 6-2-3 may be applied in combination.

[0220] 10A and 10B are diagrams showing examples of transmission of CSI and HARQ-ACK according to the combinations of options 6-1-1 and 6-2-1. In the examples shown in FIGS. 10A and 10B, CSI and HARQ-ACK are configured to overlap within one slot. In the example shown in FIG. 10A, the CSI and HARQ-ACK are associated with different panels. In the example shown in FIG. 10B, the CSI and HARQ-ACK are associated with the same panel.

[0221] In the examples shown in FIGS. 10A and 10B, the UE multiplexes / maps CSI and HARQ-ACK onto one PUCCH resource for transmission.

[0222] 11A and 11B are diagrams showing examples of transmission of CSI and HARQ-ACK according to the combinations of options 6-1-1 and 6-2-2. In the examples shown in FIGS. 11A and 11B, CSI and HARQ-ACK are configured to overlap within one slot. In the example shown in FIG. 11A, the CSI and HARQ-ACK are associated with different panels. In the example shown in FIG. 11B, the CSI and HARQ-ACK are associated with the same panel.

[0223] In the example shown in Figure 11A, the UE transmits CSI on the PUCCH resource for CSI and transmits HARQ-ACK on the PUCCH resource for HARQ-ACK. In the example shown in Figure 11B, the UE multiplexes / maps CSI and HARQ-ACK onto one PUCCH resource for transmission.

[0224] 12A and 12B are diagrams showing examples of transmission of CSI and HARQ-ACK according to the combinations of options 6-1-2 and 6-2-2. In the examples shown in FIGS. 12A and 12B, CSI and HARQ-ACK are configured to overlap within one slot. In the example shown in FIG. 12A, the CSI and HARQ-ACK are associated with different panels. In the example shown in FIG. 12B, the CSI and HARQ-ACK are associated with the same panel.

[0225] In the example shown in Figure 12A, the UE transmits CSI on the PUCCH resource for CSI and transmits HARQ-ACK on the PUCCH resource for HARQ-ACK. In the example shown in Figure 12B, the UE drops the CSI and transmits HARQ-ACK (only HARQ-ACK).

[0226] In the sixth embodiment, when CSI and HARQ-ACK are multiplexed / mapped in one PUCCH resource and the PUCCH resource for CSI overlaps with the PUCCH resource for HARQ-ACK indicated by the DCI, the UE may multiplex / map the CSI and HARQ-ACK in the PUCCH resource indicated by the DCI and transmit them.

[0227] The DCI may be, for example, a DCI that schedules the PDSCH (scheduling DCI).

[0228] In the sixth embodiment, when CSI and HARQ-ACK are multiplexed / mapped in one PUCCH resource and the PUCCH resource for CSI overlaps with the PUCCH resource for HARQ-ACK that is not indicated using DCI, the UE may multiplex / map the CSI and HARQ-ACK in the PUCCH resource for CSI and transmit them.

[0229] The HARQ-ACK may be, for example, a HARQ-ACK that does not correspond to a scheduling DCI, or a HARQ-ACK that corresponds to a PDSCH of semi-persistent scheduling (SPS).

[0230] According to the sixth embodiment described above, even if CSI and HARQ-ACK overlap when simultaneous transmission using multiple panels of PUCCH is performed, CSI / HARQ-ACK can be transmitted appropriately.

[0231] <Variations> In the second to sixth embodiments, with regard to the setting method for options X-Y-3 (X is an integer from 2 to 6, and Y is 1 or 2), each option may be set based on different (independent) setting information (signaling).

[0232] Regarding the configuration method for options X-Y-3 in the second to sixth embodiments, at least two of the options (or all of the options) may be configured based on common (joint) configuration information (signaling).

[0233] In each embodiment of the present disclosure, "associated with different panels" and "associated with the same panel" may be read interchangeably.

[0234] The UE may be configured to at least one of the following Mode 1 / Mode 2. The configuration may be based on reported UE capability information.

[0235] Mode 1: Time division multiplexed (TDM) / space division multiplexed (SDM) / frequency division multiplexed (FDM) PUCCH repetition (for improved reliability). Mode 2: PUCCH MIMO (Multi-Input Multi-Output) (for high PUCCH throughput / high resource efficiency).

[0236] The PUCCH MIMO may be a MIMO with a rank / layer greater than one.

[0237] For the above-mentioned scheme 1, the UE may transmit UCI using multiple PUCCHs using multiple panels (transmission panels), and the PUCCH resource indicator (PRI) field included in the DCI may be extended to indicate multiple PUCCH resources in one PUCCH resource set.

[0238] In the above-described scheme 2, UCI may be transmitted using one PUCCH with multiple panels (transmission panels). In this case, one PRI field may be used to indicate one PUCCH resource. Multiple layers / time resources / frequency resources may be configured for one PUCCH resource.

[0239] Similar to the layer mapping for codewords, layer mapping for UCI may be specified / applied.

[0240] <Other Embodiments> A higher layer parameter (RRC IE) / UE capability corresponding to a function (feature) in at least one of the above embodiments may be defined. The UE capability may indicate support of this function.

[0241] A UE configured with higher layer parameters corresponding to the function (enabling the function) may perform the function. It may also be specified that "a UE not configured with higher layer parameters corresponding to the function shall not perform the function (for example, in accordance with Rel. 15 / 16 / 17)."

[0242] A UE that reports a UE capability indicating that it supports the feature may perform the feature. It may also be specified that a UE that does not report a UE capability indicating that it supports the feature shall not perform the feature (e.g., in accordance with Rel. 15 / 16 / 17).

[0243] If the UE reports a UE capability indicating that it supports the function and the corresponding higher layer parameters are configured, the UE may perform the function. It may also be specified that "if the UE does not report a UE capability indicating that it supports the function or if the corresponding higher layer parameters are not configured, the UE shall not perform the function (e.g., in accordance with Rel. 15 / 16 / 17)."

[0244] The UE capability may indicate whether the UE supports this feature.

[0245] The function may be the application of simultaneous UL transmission using multiple panels.

[0253] (Wireless Communication System) The configuration of a wireless communication system according to an embodiment of the present disclosure will be described below. In this wireless communication system, communication is performed using any one of the wireless communication methods according to the above embodiments of the present disclosure or a combination thereof.

[0254] 13 is a diagram illustrating an example of a schematic configuration of a wireless communication system according to an embodiment. The wireless communication system 1 may be a system that realizes communication using Long Term Evolution (LTE) or 5th generation mobile communication system New Radio (5G NR) specified by the Third Generation Partnership Project (3GPP).

[0255] The wireless communication system 1 may also support dual connectivity between multiple Radio Access Technologies (RATs) (Multi-RAT Dual Connectivity (MR-DC)). MR-DC may 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.

[0256] In EN-DC, the LTE (E-UTRA) base station (eNB) is the master node (Master Node (MN)), and the NR base station (gNB) is the secondary node (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.

[0257] The wireless communication system 1 may support dual connectivity between multiple base stations within the same RAT (for example, dual connectivity in which both the MN and SN are NR base stations (gNBs) (NR-NR Dual Connectivity (NN-DC))).

[0258] The wireless communication system 1 may include a base station 11 that forms a macrocell C1 with a relatively wide coverage, and base stations 12 (12a-12c) that are located within the macrocell C1 and form small cells C2 that are smaller than the macrocell C1. A user terminal 20 may be located within at least one of the cells. The locations and numbers of the cells and user terminals 20 are not limited to the embodiment shown in the figure. Hereinafter, when there is no need to distinguish between the base stations 11 and 12, they will be collectively referred to as base station 10.

[0259] The user terminal 20 may be connected to at least one of the multiple base stations 10. The user terminal 20 may utilize at least one of carrier aggregation (CA) using multiple component carriers (CCs) and dual connectivity (DC).

[0260] Each CC may be included in at least one of a first frequency band (Frequency Range 1 (FR1)) and a second frequency band (Frequency Range 2 (FR2)). The macro cell C1 may be included in FR1, and the small cell C2 may be included in FR2. For example, FR1 may be a frequency band of 6 GHz or less (sub-6 GHz), and FR2 may be a frequency band higher than 24 GHz (above-24 GHz). Note that the frequency bands and definitions of FR1 and FR2 are not limited to these, and for example, FR1 may correspond to a higher frequency band than FR2.

[0261] Furthermore, the user terminal 20 may perform communication using at least one of time division duplex (TDD) and frequency division duplex (FDD) in each CC.

[0262] The multiple base stations 10 may be connected by wire (e.g., optical fiber compliant with the Common Public Radio Interface (CPRI), an X2 interface, etc.) or wirelessly (e.g., NR communication). For example, when NR communication is used as a backhaul between the base stations 11 and 12, the base station 11 corresponding to the upper station may be called an Integrated Access Backhaul (IAB) donor, and the base station 12 corresponding to the relay station (relay) may be called an IAB node.

[0263] The base station 10 may be connected to the core network 30 directly or via another base station 10. The core network 30 may 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.

[0264] The user terminal 20 may be a terminal that supports at least one of communication methods such as LTE, LTE-A, and 5G.

[0265] An Orthogonal Frequency Division Multiplexing (OFDM)-based radio access scheme may be used in the wireless communication system 1. For example, 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), or the like may be used in at least one of the downlink (DL) and uplink (UL).

[0266] The radio access scheme may also be called a waveform. Note that in the wireless communication system 1, other radio access schemes (e.g., other single-carrier transmission schemes, other multi-carrier transmission schemes) may be used as the UL and DL radio access schemes.

[0267] In the wireless communication system 1, 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)), etc. may be used as the downlink channel.

[0268] Furthermore, 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)), or the like may be used as an uplink channel.

[0269] The PDSCH transmits user data, higher layer control information, a System Information Block (SIB), etc. The PUSCH may transmit user data, higher layer control information, etc. Furthermore, the PBCH may transmit a Master Information Block (MIB).

[0270] Lower layer control information may be transmitted by the PDCCH. The lower layer control information may include, for example, Downlink Control Information (DCI) including scheduling information for at least one of the PDSCH and the PUSCH.

[0271] Note that the DCI for scheduling the PDSCH may be referred to as a DL assignment, a DL DCI, etc., and the DCI for scheduling the PUSCH may be referred to as a UL grant, a UL DCI, etc. Note that the PDSCH may be replaced with DL data, and the PUSCH may be replaced with UL data.

[0272] A control resource set (CORESET) and a search space may be used to detect the PDCCH. The CORESET corresponds to resources for searching for DCI. The search space corresponds to a search region and a search method for PDCCH candidates. One CORESET may be associated with one or more search spaces. The UE may monitor the CORESET associated with a certain search space based on the search space configuration.

[0273] One search space may correspond to PDCCH candidates corresponding to one or more aggregation levels. One or more search spaces may be referred to as a search space set. Note that the terms "search space," "search space set," "search space configuration," "search space set configuration," "CORESET," "CORESET configuration," and the like in the present disclosure may be read interchangeably.

[0274] The PUCCH may transmit uplink control information (UCI) including at least one of channel state information (CSI), delivery confirmation information (which may be called, for example, Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK), ACK / NACK, etc.), and scheduling request (SR). The PRACH may transmit a random access preamble for establishing a connection with a cell.

[0275] In the present disclosure, downlink, uplink, etc. may be expressed without adding "link." Also, various channels may be expressed without adding "Physical" to the beginning.

[0276] In the wireless communication system 1, a synchronization signal (SS), a downlink reference signal (DL-RS), etc. may be transmitted. In the wireless communication system 1, as the DL-RS, a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), a phase tracking reference signal (PTRS), etc. may be transmitted.

[0277] 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 an SS (PSS, SSS) and a PBCH (and a DMRS for the PBCH) may be referred to as an SS / PBCH block, an SS Block (SSB), or the like. Note that the SS, SSB, and the like may also be referred to as a reference signal.

[0278] Furthermore, in the wireless communication system 1, a sounding reference signal (SRS), a demodulation reference signal (DMRS), or the like may be transmitted as an uplink reference signal (UL-RS). Note that the DMRS may also be called a user equipment-specific reference signal (UE-specific reference signal).

The communication device 1004 may be configured to include a high-frequency switch, a duplexer, a filter, a frequency synthesizer, etc. to realize at least one of frequency division duplex (FDD) and time division duplex (TDD). For example, the above-mentioned transmission / reception unit 120 (220), transmission / reception antenna 130 (230), etc. may be realized by the communication device 1004. The transmission / reception unit 120 (220) may be implemented as a transmission unit 120a (220a) and a reception unit 120b (220b) that are physically or logically separated.

[0339] The input device 1005 is an input device (e.g., a keyboard, a mouse, a microphone, a switch, a button, a sensor, etc.) that accepts input from the outside. The output device 1006 is an output device (e.g., a display, a speaker, a light emitting diode (LED) lamp, etc.) that outputs to the outside. Note that the input device 1005 and the output device 1006 may be integrated into one device (e.g., a touch panel).

[0340] Furthermore, each device, such as the processor 1001 and the memory 1002, is connected by a bus 1007 for communicating information. The bus 1007 may be configured using a single bus, or may be configured using different buses between each device.

[0341] Furthermore, the base station 10 and the user terminal 20 may 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 some or all of the functional blocks may be realized using this hardware. For example, the processor 1001 may be implemented using at least one of these pieces of hardware.

[0342] (Modifications) Note that terms described in the present disclosure and terms necessary for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, a channel, a symbol, and a signal (signal or signaling) may be interchangeable. A signal may also be a message. A reference signal may be abbreviated as RS, and may also be called a pilot, pilot signal, etc. depending on the applicable standard. A component carrier (CC) may also be called a cell, frequency carrier, carrier frequency, etc.

[0343] A radio frame may be composed of one or more periods (frames) in the time domain. Each of the one or more periods (frames) constituting a radio frame may be called a subframe. Furthermore, a subframe may be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0344] Here, the numerology may be a communication parameter applied to at least one of transmission and reception of a signal or channel, and may indicate at least one of, for example, Subcarrier Spacing (SCS), bandwidth, symbol length, cyclic prefix length, Transmission Time Interval (TTI), number of symbols per TTI, radio frame structure, specific filtering performed by a transceiver in the frequency domain, and specific windowing performed by a transceiver in the time domain.

[0345] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may also be a time unit based on numerology.

[0346] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (PUSCH) mapping type B.

[0347] A radio frame, a subframe, a slot, a minislot, and a symbol all represent time units for transmitting signals. The radio frame, the subframe, the slot, the minislot, and the symbol may be referred to by other names corresponding to the radio frame, the subframe, the slot, the minislot, and the symbol. Note that the time units such as a frame, a subframe, a slot, a minislot, and a symbol in the present disclosure may be interchangeable.

[0348] For example, one subframe may be referred to as a TTI, or multiple consecutive subframes may be referred to as a TTI, or one slot or one minislot may be referred to as a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0349] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.

[0350] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a 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.

[0351] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0352] A TTI having a time length of 1 ms may be called a regular TTI (TTI in 3GPP Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0353] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than the TTI length of a long TTI and greater than or equal to 1 ms.

[0354] 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 in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may be determined based on numerology.

[0355] In addition, an RB may include one or more symbols in the time domain and may have a length of one slot, one minislot, one subframe, or one TTI, each of which may be composed of one or more resource blocks.

[0356] In addition, one or more RBs may be referred to as a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0357] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0358] A Bandwidth Part (BWP), which may also be referred to as a partial bandwidth, may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a Common Reference Point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0359] The BWP may include a UL BWP (BWP for UL) and a DL BWP (BWP for DL). One or more BWPs may be configured for a UE within one carrier.

[0360] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0361] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples. For example, the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc. may be changed in various ways.

[0362] Furthermore, the information, parameters, etc. described in the present disclosure may be expressed using absolute values, may be expressed using relative values ​​from a predetermined value, or may be expressed using other corresponding information. For example, a radio resource may be indicated by a predetermined index.

[0363] The names used for parameters and the like in this disclosure are not intended to be limiting in any way. Furthermore, the mathematical expressions and the like using these parameters may differ from those explicitly disclosed in this disclosure. The various channels (PUCCH, PDCCH, etc.) and information elements may be identified by any suitable names, and therefore the various names assigned to these various channels and information elements are not intended to be limiting in any way.

For example, data, instructions, commands, information, signals, bits, symbols, chips, etc. that may be referred to throughout the above description may be represented by voltages, currents, electromagnetic waves, magnetic fields or magnetic particles, optical fields or photons, or any combination thereof.

[0365] Furthermore, information, signals, etc. may be output from a higher layer to a lower layer and / or from a lower layer to a higher layer. Information, signals, etc. may be input / output via multiple network nodes.

[0366] Input and output information, signals, etc. may be stored in a specific location (for example, memory) or may be managed using a management table. Input and output information, signals, etc. may be overwritten, updated, or added. Output information, signals, etc. may be deleted. Input information, signals, etc. may be transmitted to another device.

[0367] The notification of information is not limited to the aspects / embodiments described in the present disclosure, and may be performed using other methods. For example, the notification of information in the present disclosure may be performed by physical layer signaling (e.g., Downlink Control Information (DCI) and Uplink Control Information (UCI)), higher layer signaling (e.g., Radio Resource Control (RRC) signaling, broadcast information (Master Information Block (MIB) and System Information Block (SIB)), Medium Access Control (MAC) signaling), other signals, or a combination thereof.

[0368] Note that the physical layer signaling may be referred to as Layer 1 / Layer 2 (L1 / L2) control information (L1 / L2 control signal), L1 control information (L1 control signal), etc. Furthermore, the RRC signaling may be referred to as an RRC message, such as an RRC Connection Setup message or an RRC Connection Reconfiguration message. Furthermore, the MAC signaling may be notified using, for example, a MAC Control Element (CE).

[0369] Furthermore, notification of specified information (e.g., notification that "it is X") is not limited to explicit notification, but may be made implicitly (e.g., by not notifying the specified information or by notifying other information).

[0370] The determination may be made by a value represented by one bit (0 or 1), by a Boolean value represented by true or false, or by a comparison of numerical values ​​(e.g., comparison with a predetermined value).

When a base station accommodates multiple cells, the overall coverage area of ​​the base station can be partitioned into multiple smaller areas, and each smaller area can be provided with communication service by a base station subsystem (e.g., a small indoor base station (Remote Radio Head (RRH))). The terms "cell" or "sector" refer to part or all of the coverage area of ​​a base station and / or base station subsystem that provides communication service within that coverage.

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

[0387] The information service unit 59 may include input devices (e.g., keyboards, mice, microphones, switches, buttons, sensors, touch panels, etc.) that accept input from the outside, and may also include output devices (e.g., displays, speakers, LED lamps, touch panels, etc.) that output to the outside.

The driving assistance system unit 64 also transmits and receives various information via the communication module 60 to realize driving assistance functions or autonomous driving functions.

[0389] The communication module 60 can communicate with the microprocessor 61 and components of the vehicle 40 via the communication port 63. For example, the communication module 60 transmits and receives data (information) via the communication port 63 to and from the drive unit 41, steering unit 42, accelerator pedal 43, brake pedal 44, shift lever 45, left and right front wheels 46, left and right rear wheels 47, axles 48, the microprocessor 61 and memory (ROM, RAM) 62 in the electronic control unit 49, and the various sensors 50-58, which are provided in the vehicle 40.

[0390] The communication module 60 is a communication device that can be controlled by the microprocessor 61 of the electronic control unit 49 and can communicate with an external device. For example, it transmits and receives various information to and from the external device via wireless communication. The communication module 60 may be located either inside or outside the electronic control unit 49. The external device may be, for example, the base station 10 or the user terminal 20 described above. Furthermore, the communication module 60 may be, for example, at least one of the base station 10 and the user terminal 20 described above (or may function as at least one of the base station 10 and the user terminal 20).

For example, the PUSCH transmitted by the communication module 60 may include information based on the above-mentioned input.

[0392] The communication module 60 receives various information (traffic information, traffic signal information, vehicle distance information, etc.) transmitted from an external device and displays it on an information service unit 59 provided in the vehicle. The information service unit 59 may also be called an output unit that outputs information (for example, outputs information to a device such as a display or speaker based on the PDSCH received by the communication module 60 (or data / information decoded from the PDSCH)).

[0393] Furthermore, the communication module 60 stores various information received from external devices in a memory 62 that can be used by the microprocessor 61.

[0394] Furthermore, a base station in the present disclosure may be read as a user terminal. For example, the aspects / embodiments of the present disclosure may be applied to a configuration in which communication between a base station and a user terminal is replaced with communication between multiple user terminals (which may be called, for example, Device-to-Device (D2D) or Vehicle-to-Everything (V2X)). In this case, the user terminal 20 may be configured to have the functions of the base station 10 described above. Furthermore, terms such as "uplink" and "downlink" may be read as terms corresponding to terminal-to-terminal communication (for example, "sidelink"). For example, terms such as an uplink channel and a downlink channel may be read as a sidelink channel.

[0395] Similarly, the user terminal in the present disclosure may be read as a base station, in which case the base station 10 may be configured to have the functions of the user terminal 20 described above.

[0396] In the present disclosure, an operation described as being performed by a base station may be performed by its upper node in some cases. It is apparent that in a network including one or more network nodes having a base station, various operations performed for communication with a terminal may be performed by the base station, one or more network nodes other than the base station (such as, but not limited to, a Mobility Management Entity (MME), a Serving-Gateway (S-GW), etc.), or a combination thereof.

[0400] As used in this disclosure, any reference to an element using a designation such as "first," "second," etc. does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

[0401] The term "determining" as used in this disclosure may encompass a wide variety of actions. For example, "determining" may be considered to be judging, calculating, computing, processing, deriving, investigating, looking up, search, inquiry (e.g., looking up in a table, database, or another data structure), ascertaining, etc.

[0407] In the present disclosure, the term "A and B are different" may mean "A and B are different from each other." The term may also mean "A and B are each different from C." Terms such as "separate" and "coupled" may also be interpreted in the same way as "different."

[0408] When the terms "include," "including," and variations thereof are used in this disclosure, these terms are intended to be inclusive, similar to the term "comprising." Furthermore, when the term "or" is used in this disclosure, it is not intended to be an exclusive or.

[0409] In this disclosure, where articles are added by translation, such as a, an, and the in English, the disclosure may include that the nouns following these articles are in the plural form.
