Description

Terminal and Communication Method

[0001] The present disclosure relates to a terminal and a communication method.

[0002] The 3rd Generation Partnership Project (3GPP (registered trademark)) has standardized the 5th generation mobile communication system (also called 5G, New Radio (NR) or Next Generation (NG)), and is further promoting the specification of the next generation called Beyond 5G, 5G Evolution, or 6G.

[0003] In 5G, as requirements, technologies that satisfy a large-capacity system, high data transmission speed, low latency, simultaneous connection of a large number of terminals, low cost, power saving, etc. are being studied (for example, Non-Patent Document 1).

[0004] With the expansion of the mobile communication system as described above, the use and spread of XR (extended reality) such as VR (virtual reality), AR (augmented reality), and MR (mixed reality), which enable the combination of the real world and the virtual world (virtual content), are expected, and in 3GPP, discussions on XR expansion are underway for Release 19 (for example, see Non-Patent Document 2).

[0005] Regarding XR expansion, for example, expansions related to measurement gaps (MG: Measurement Gap) and scheduling restrictions are widely discussed.

[0006] For example, regarding the scheduling restrictions for inter-frequency RRM (Radio Resource Management) measurements in FR1 and FR2 with measurement gaps and intra-frequency RRM measurements in FR2 without measurement gaps, identifying expansions to reduce the impact on capacity and individual terminals may be included in the scope of future standards.

[0007] At the RAN1#119 meeting, it was agreed that a 1-bit gap / limit skipping instruction may be included in DCI format 0_3 / 1_3. This agreement applies to concurrently scheduled cells in the case of in-band CAs with the same SCS.

[0008] 3GPP TS 38.300 V17.6.0 (2023-09)“Moderator's summary for REL-19 RAN2 topic Enhancements for XR”, RP-232619, 3GPP TSG-RAN Meeting #101, 3GPP, September 2023 “New WID: XR (eXtended Reality) for NR Phase 3”, RP-234080, 3GPP TSG-RAN Meeting #102, 3GPP, December 2023

[0009] However, the terminal behavior when concurrently scheduled cells are interband cells and / or cells with different SCSs has not been adequately considered, and further investigation is needed.

[0010] One aspect of this disclosure is to provide a terminal and communication method that can operate appropriately when the concurrently scheduled cells are interband cells and / or cells having different SCSs.

[0011] A terminal according to one aspect of the present disclosure includes a receiving unit that receives information indicating whether instruction information relating to an instruction to skip a measurement in a measurement opportunity is included in downlink control information used to simultaneously schedule multiple carriers, and a control unit that determines, based on the information, whether the instruction information is included in the downlink control information, wherein the control unit decides to ignore the instruction information included in the downlink control information if the simultaneously scheduled multiple carriers have different subcarrier intervals and / or are in different frequency bands.

This figure shows an example of the configuration of a vehicle according to an embodiment of the present disclosure.

[0013] Hereinafter, an embodiment relating to one aspect of this disclosure will be described with reference to the drawings. Note that the embodiment described below is merely an example, and the embodiments to which this disclosure applies are not limited to the embodiments described below.

[0014] <Wireless Communication System> Figure 1 shows an example of a wireless communication system 10 according to an embodiment of the present disclosure. The wireless communication system 10 is a wireless communication system in accordance with 5G NR and includes Next Generation-Radio Access Network 20 (hereinafter referred to as NG-RAN 20) and terminal 200 (hereinafter also referred to as UE (User Equipment) 200).

[0015] The wireless communication system 10 may be a wireless communication system that conforms to a method called Beyond 5G, 5G Evolution, or 6G.

[0016] NG-RAN20 includes base station 100A (hereinafter also referred to as gNB100A) and base station 100B (hereinafter also referred to as gNB100B). When it is not necessary to distinguish between gNB100A, gNB100B, etc., they are collectively referred to as gNB or base station 100. Furthermore, the number of gNBs and UEs is not limited to the example shown in Figure 1.

[0017] NG-RAN20 actually includes multiple NG-RAN nodes, specifically gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). Note that NG-RAN20 and 5GC may simply be referred to as "the network." Furthermore, in the following, gNB may be read as "network (NW)."

[0018] gNB100A and gNB100B are, for example, base stations compliant with 5G, and perform 5G-compliant wireless communication with UE200. gNB100A, gNB100B, and UE200 may support MIMO (Multiple-Input Multiple-Output), which generates a more directional beam BM by controlling the radio signals transmitted from multiple antenna elements; Carrier Aggregation (CA), which uses multiple component carriers (CC); and Dual Connectivity (DC), which enables communication between the UE and each of the two NG-RAN nodes.

[0019] Furthermore, the wireless communication system 10 may support multiple frequency ranges (FRs). Figure 2 shows an example of an FR used in the wireless communication system 10. As shown in Figure 2, the wireless communication system 10 may support FR1 and FR2. The frequency bands of each FR are, for example, as follows: ・FR1: 410 MHz to 7.125 GHz ・FR2: 24.25 GHz to 52.6 GHz

[0020] In FR1, a subcarrier spacing (SCS) of 15 kHz, 30 kHz, or 60 kHz may be used, and a bandwidth (BW) of 5 to 100 MHz may be used. FR2 is a higher frequency than FR1, and an SCS of 60 kHz or 120 kHz (240 kHz may be included) may be used, and a bandwidth (BW) of 50 to 400 MHz may be used.

[0021] Note that SCS may also be interpreted as numerology. Numerology is defined in 3GPP TS 38.300 and corresponds to a single subcarrier interval in the frequency domain.

[0022] Furthermore, the wireless communication system 10 may support higher frequency bands than the FR2 frequency band. Specifically, the wireless communication system 10 may support frequency bands exceeding 52.6 GHz and up to 114.25 GHz. Such high frequency bands may be conveniently referred to as "FR2x". When using a bandwidth exceeding 52.6 GHz, CP-OFDM (Cyclic Prefix - Orthogonal Frequency Division Multiplexing) / DFT-S-OFDM (Discrete Fourier Transform - Spread - Orthogonal Frequency Division Multiplexing) with a larger SCS may be applied.

[0023] Figure 3 shows an example of the configuration of wireless frames (system frames), subframes, and slots used in the wireless communication system 10. As shown in Figure 3, one slot consists of 14 symbols, and the larger (wider) the SCS, the shorter the symbol period (and slot period). However, the SCS is not limited to the interval (frequency) shown in Figure 3. For example, 480 kHz, 960 kHz, etc. may be used as the SCS.

[0024] Furthermore, the number of symbols constituting one slot does not necessarily have to be 14 (for example, it could be 28 or 56 symbols, etc.). In addition, the number of slots per subframe may differ depending on the SCS.

[0025] The time direction (t) shown in Figure 3 may also be called the time domain, symbol period, or symbol time. The frequency direction may also be called the frequency domain, resource block, subcarrier, bandwidth part (BWP), or similar.

[0026] The gNB100 transmits control information, setting information, etc., to the UE200 as a downlink (DL) signal.

[0027] Furthermore, for example, the gNB100 receives control information, data signals, and information regarding the processing capabilities of the UE200 (terminal capability information; e.g., UE capability) from the UE200 as uplink (UL) signals.

[0028] The channels used to transmit DL signals include, for example, a data channel and a control channel. For example, the data channel may include a Physical Downlink Shared Channel (PDSCH), and the control channel may include a Physical Downlink Control Channel (PDCCH). For example, gNB100 transmits control information to UE200 using the PDCCH and transmits DL data signals using the PDSCH. Note that PDSCH is an example of a Downlink Shared Channel, and PDCCH is an example of a Downlink Control Channel. Note that PDCCH may be interpreted as Downlink Control Information (DCI), control information, etc., transmitted in the PDCCH.

[0029] The reference signals included in the DL signal may include, for example, at least one of the following: DMRS (Demodulation Reference Signal), PTRS (Phase Tracking Reference Signal), CSI-RS (Channel State Information - Reference Signal), SRS (Sounding Reference Signal), and PRS (Positioning Reference Signal) for position information. For example, reference signals such as DMRS and PTRS are used to demodulate the DL data signal and are transmitted using PDSCH.

[0030] The UE200 is a communication device equipped with wireless communication capabilities, such as a smartphone, mobile phone, tablet, wearable device, or M2M (Machine-to-Machine) communication module.

[0031] The UE200 receives control signals or data signals from the gNB100 via DL and transmits control signals or data signals to the gNB100 via UL, thereby utilizing various communication services provided by the wireless communication system 10. The UE200 also receives various reference signals transmitted from the gNB100 and performs propagation path quality measurements based on the reception results of these reference signals.

[0032] For example, UE200 receives control information, setting information, etc., from gNB100 as DL signals.

[0033] Furthermore, for example, UE200 transmits control information, data signals, terminal capability information of UE200, etc., to gNB100 as UL signals.

[0034] The channels used to transmit UL signals include, for example, a data channel and a control channel. For example, the data channel may include a Physical Uplink Shared Channel (PUSCH), and the control channel may include a Physical Uplink Control Channel (PUCCH). For example, UE200 transmits control information using PUCCH and transmits UL data signals using PUSCH. Note that PUSCH is an example of an uplink shared channel, and PUCCH is an example of an uplink control channel. Note that PUSCH or PUCCH may be interpreted as Uplink Control Information (UCI), control information, etc., transmitted in PUSCH or PUCCH.

[0035] The reference signals included in the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRSRS, and PRS for location information. For example, reference signals such as DMRS and PTRS are used to demodulate the UL data signal and are transmitted using PUSCH. Hereafter, "and / or" may be written as " / ".

[0036] <Current Status of Discussions Regarding XR> XR presents attractive use cases for future wireless communication systems. On the other hand, XR also presents challenges that need to be considered and addressed. One such challenge is that 3GPP is discussing XR extensions toward Rel-19 (see, for example, Non-Patent Document 2), and is broadly discussing extensions related to measurement gaps and scheduling limitations.

[0037] <Rel-19 XR WID Objectives> The following matters were considered in the WI for XR in Rel-19 (see Non-Patent Document 3): - To define enhancements to enable transmission / reception in gaps / limitations caused by RRM measurement (inter-frequency RRM measurement gaps / intra-frequency measurements / other scheduling restrictions, etc.).

[0038] In other words, to prioritize XR, it is possible to consider skipping the measurement gap for measuring the received signal and skipping the scheduling limit to prioritize the measurement of the received signal.

[0039] <DCI Format 0_3 / 1_3> The DCI format for multi-carrier scheduling of PUSCH is agreed to be called DCI Format 0_3. The DCI format for multi-carrier scheduling of PDSCH is agreed to be called DCI Format 1_3. DCI Format 0_3 / 1_3 can simultaneously schedule combinations of cells included in a Set of Cells. In other words, DCI Format 0_3 / 1_3 can schedule PUSCH / PDSCH on a Set of Cells. Multi-carrier scheduling may also be called multi-cell scheduling. Below, Set of Cells may be referred to as SoCs.

[0040] <RAN1#119 Agreement> At the RAN1#119 meeting, it was agreed that, in addition to DCI formats 0_1 / 1_1 and 0_2 / 1_2, a one-bit indication may be included as part of DCI format 0_3 / 1_3 for explicit DCI indication to skip specific gaps / limits. In other words, it was agreed that one bit of DCI format 0_3 / 1_3 may be used to skip specific gaps / limits.

[0041] Explicit instructions can be set individually for each DCI format by higher layers such as RRC. For example, whether or not to include fields for skipping specific gaps / limitations in DCI formats 0_1 / 1_1, 0_2 / 1_2, and 0_3 / 1_3 can be set by higher layers such as RRC.

[0042] A skipping indication may correspond to the first gap / limitation opportunity among co-scheduled cells by DCI (Type-1C field). For example, the first gap / limitation opportunity among multiple co-scheduled cells may be skipped by DCI. DCI does not have a field for per-cell skipping (in the Type-1C field, a single value is applied only to one cell within the SoCs (see FIG. 4)).

[0043] The above is only applicable to the case of intra-band carrier aggregation (CA) (the SCS of cells within the set of co-scheduled cells is the same).

[0044] <Consideration> As described in the above <RAN1#119 agreement>, in the RAN1#119 meeting, it was agreed that a 1-bit gap / limitation skipping indication can be included in DCI format 0_3 / 1_3.

[0045] The above agreement is applicable to the case of intra-band CA with the same SCS for co-scheduled cells. The behavior of the terminal when the co-scheduled cells scheduled by DCI format 0_3 / 1_3 are inter-band cells / cells with different SCSs is not clear. Therefore, the terminal may not operate properly in some cases.

[0046] Therefore, the present disclosure provides a technique that enables the terminal to operate properly when the co-scheduled cells are inter-band cells and / or cells with different SCSs.

[0047] In the present disclosure, a 1-bit indication, a 1-bit skipping indication, and an indication may be used interchangeably. Skipping, skip, and stop may be used interchangeably.

[0048] <Proposal 1> The presence (or absence) of a 1-bit indication in DCI format 0_3 / 1_3 is determined based on the following options 1 to 4.

[0049] <Proposal 1: Option 1> The presence of a 1-bit indication in DCI format 0_3 / 1_3 is determined solely based on the explicit RRC configuration.

[0050] (1) If an explicit RRC parameter indicates the presence of a one-bit indicator in DCI format 0_3 / 1_3, then a one-bit indicator exists in DCI format 0_3 / 1_3.

[0051] Even if an explicit RRC parameter indicates the presence of a one-bit indication in DCI format 0_3 / 1_3, the one-bit indication is ignored if the concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have different SCSs / are in different frequency bands (inter-band).

[0052] For example, even if the presence of a one-bit indication is explicitly indicated by the RRC parameter, the terminal will ignore the one-bit indication in DCI format 0_3 / 1_3 if the concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have different SCSs / are in different frequency bands. In other words, the terminal will ignore the one-bit indication even if a field for the one-bit indication exists in DCI format 0_3 / 1_3.

[0053] If simultaneously scheduled cells according to DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band (intra-band), the 1-bit indication applies to the first gap / limit opportunity.

[0054] For example, if the presence of a 1-bit instruction is explicitly indicated by the RRC parameter, and concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band, the terminal applies the 1-bit instruction to the first gap / limit opportunity after receiving DCI format 0_3 / 1_3.

[0055] (2) If the explicit RRC parameter does not indicate the presence of a one-bit indicator in DCI format 0_3 / 1_3, then the one-bit indicator does not exist in DCI format 0_3 / 1_3.

[0056] <Proposal 1: Option 2> The presence of a 1-bit indication in DCI format 0_3 / 1_3 is determined based on the explicit RRC setting and the properties (or settings or state) of the concurrently scheduled cell scheduled by DCI format 0_3 / 1_3.

[0057] (1) If an explicit RRC parameter indicates the presence of a 1-bit indication in DCI format 0_3 / 1_3, and the concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have different SCSs / are in different frequency bands, then the 1-bit indication does not exist in DCI format 0_3 / 1_3.

[0058] For example, even if an explicit RRC parameter indicates the presence of a one-bit instruction in DCI format 0_3 / 1_3, the terminal will assume that the one-bit instruction does not exist in DCI format 0_3 / 1_3 if the concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have different SCSs / are in different frequency bands.

[0059] (2) The 1-bit indication exists in DCI format 0_3 / 1_3 if the explicit RRC parameter indicates the presence of a 1-bit indication in DCI format 0_3 / 1_3, and concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band.

[0060] For example, the terminal assumes that a single bit instruction exists in DCI format 0_3 / 1_3 if an explicit RRC parameter indicates the presence of a single bit instruction in DCI format 0_3 / 1_3, and concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band. The terminal skips the first gap / limit opportunity based on the single bit instruction present in DCI format 0_3 / 1_3.

[0061] (3) Otherwise, no one-bit indication exists. For example, if an explicit RRC parameter does not indicate the presence of a one-bit indication in DCI format 0_3 / 1_3, the terminal assumes that no one-bit indication exists in DCI format 0_3 / 1_3, even if concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band.

[0062] <Proposal 1: Option 3> The presence of a single-bit instruction for DCI format 0_3 / 1_3 is implicitly determined based on the properties of the set of concurrently scheduled cells (the set of candidate cells for concurrently scheduled cells) configured for DCI format 0_3 / 1_3. In other words, the presence of a single-bit instruction for DCI format 0_3 / 1_3 is implicitly determined based on the properties of the SoCs.

[0063] A 1-bit indication exists in DCI format 0_3 / 1_3 if a set of concurrently scheduled cells configured for DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band.

[0064] For example, it is assumed that if the SoCs configured in higher-layer signaling such as RRC have the same SCS and are in the same frequency band, then a 1-bit instruction exists in DCI format 0_3 / 1_3.

[0065] Otherwise, there is no 1-bit instruction. For example, if the SoCs configured in higher-layer signaling such as RRC have different SCSs and are in different frequency bands, the terminal assumes that there is no 1-bit instruction in DCI format 0_3 / 1_3.

[0066] <Proposal 1: Option 4> The presence of a 1-bit indication in DCI format 0_3 / 1_3 is determined based on the explicit RRC setting and the properties of the set of concurrently scheduled cells.

[0067] (1) A one-bit indication exists in DCI format 0_3 / 1_3 if an explicit RRC parameter indicates the presence of a one-bit indication in DCI format 0_3 / 1_3, and the configured concurrently scheduled cells in the set for DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band.

[0068] For example, the terminal assumes that a one-bit instruction exists in DCI format 0_3 / 1_3 if an explicit RRC parameter indicates the presence of a one-bit instruction in DCI format 0_3 / 1_3, and if the SoCs have the same SCS and are in the same frequency band.

[0069] (2) Otherwise, the 1-bit instruction does not exist in DCI format 0_3 / 1_3.

[0070] For example, even if an explicit RRC parameter indicates the presence of a one-bit instruction in DCI format 0_3 / 1_3, the terminal will assume that the one-bit instruction does not exist in DCI format 0_3 / 1_3 if the SoCs have different SCSs / are in different frequency bands.

[0071] <Proposal 1: Summary> The terminal can operate appropriately when the concurrently scheduled cells are interband cells or cells with different SCSs, through the operation of options 1 to 4 described above.

[0072] <Proposal 1: Variation 1> If the terminal indicates the presence of a 1-bit indication in DCI format 0_3 / 1_3 in an explicit RRC setting (e.g., options 1, 2, and 4 above), it assumes that concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have the same SCS and are in the same frequency band.

[0073] The terminal determines an error if, in an explicit RRC setting, the presence of a 1-bit indication in DCI format 0_3 / 1_3 is indicated, and if concurrently scheduled cells scheduled by DCI format 0_3 / 1_3 have different SCSs / are in different frequency bands.

[0074] <Proposal 1: Variation 2> If a 1-bit indication does not exist in the DCI format 0_3 / 1_3, the field for the 1-bit indication may be padded with zeros, for example. This is because changing the length of the DCI depending on the presence or absence of the field for the 1-bit indication increases the number of blind decoding patterns for the terminal, thus increasing the load on the terminal.

[0075] <Proposal 2> In Proposal 1, gap / limit skipping according to DCI format 0_3 / 1_3 can be applied to simultaneously scheduled cells that have the same SCS and are in the same frequency band. In Proposal 2, gap / limit skipping according to DCI format 0_3 / 1_3 can be applied to simultaneously scheduled cells that have different SCSs and are in different frequency bands.

[0076] For Proposal 2, the following individual UE capabilities will be supported: • The ability to support gap / limit skipping instructions using DCI format 0_3 / 1_3 for simultaneously scheduled cells with intraband CA and the same SCS. • The ability to support gap / limit skipping instructions using DCI format 0_3 / 1_3 for simultaneously scheduled cells with interband CA and different SCS.

[0077] One-bit gap / constraint skipping instructions, applicable to cases of simultaneously scheduled cells with different SCSs / on different frequency bands, are supported in DCI format 1_3 / 0_3 depending on terminal capabilities / gNB configuration.

[0078] An explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3, and the following options 1 to 4 are provided regarding the presence of a one-bit skipping instruction when concurrently scheduled cells in DCI format 0_3 / 1_3 have different SCSs / are in different frequency bands.

[0079] <Proposal 2: Option 1> The presence of a 1-bit skipping instruction depends on the terminal's capabilities.

[0080] For example, if an explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal reports its ability to handle one-bit skipping instructions in DCI format 1_3 / 0_3 for interband CA / different SCS cases, then the one-bit skipping instruction is present.

[0081] Otherwise, the one-bit skipping instruction does not exist. For example, if an explicit RRC parameter indicates the presence of the one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal does not report terminal capability for the one-bit skipping instruction in DCI format 1_3 / 0_3 for the interband CA / different SCS case, then the one-bit skipping instruction does not exist.

[0082] <Proposal 2: Option 2> The presence of a 1-bit skipping instruction depends on the terminal capability and separate explicit settings for interband CA / different SCS.

[0083] For example, if an explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal reports its capability for a one-bit skipping instruction in DCI format 1_3 / 0_3 for the interband CA / different SCS case, and the explicit RRC parameter indicates that a one-bit skipping instruction is applicable for interband CA / different SCS, then a one-bit skipping instruction exists.

[0084] Otherwise, the one-bit skipping instruction does not exist. For example, if an explicit RRC parameter indicates the presence of the one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal reports terminal capability for the one-bit skipping instruction in DCI format 1_3 / 0_3 for the interband CA / different SCS case, and the explicit RRC parameter does not indicate that the one-bit skipping instruction is applicable for interband CA / different SCS, then the one-bit skipping instruction does not exist.

[0085] <Proposal 2: Option 3> The application of the 1-bit skipping instruction depends on the terminal's capabilities.

[0086] A 1-bit skipping instruction exists in DCI format 0_3 / 1_3.

[0087] For example, if an explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal reports its ability to apply a one-bit skipping instruction in DCI format 1_3 / 0_3 for the case of interband CA / different SCS, then the one-bit skipping instruction will be applied to the first gap / limit opportunity among the concurrently scheduled cells.

[0088] Otherwise, the one-bit skipping instruction is ignored. For example, if an explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal does not report its ability to handle one-bit skipping instructions in DCI format 1_3 / 0_3 for the interband CA / different SCS case, the terminal will ignore the one-bit skipping instruction in DCI format 1_3 / 0_3.

[0089] <Proposal 2: Option 4> The application of the 1-bit skipping instruction depends on the terminal capability and separate explicit settings for interband CA / different SCS.

[0090] A 1-bit skipping instruction exists in DCI format 0_3 / 1_3.

[0091] For example, if an explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal reports its ability to apply the one-bit skipping instruction in DCI format 1_3 / 0_3 for the interband CA / different SCS case, and the explicit RRC parameter indicates that the one-bit skipping instruction applies for the interband CA / different SCS case, then the one-bit skipping instruction applies to the first gap / limit opportunity among the concurrently scheduled cells.

[0092] Otherwise, the one-bit skipping instruction is ignored. For example, if an explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3, and the terminal does not report terminal capability for the one-bit skipping instruction in DCI format 1_3 / 0_3 for the interband CA / different SCS case, and the explicit RRC parameter indicates that the one-bit skipping instruction applies for the interband CA / different SCS case, the terminal will ignore the one-bit skipping instruction in DCI format 1_3 / 0_3.

[0093] <Proposal 2: Summary> The terminal can operate appropriately when the concurrently scheduled cells are interband cells or cells with different SCSs, through the operation of options 1 to 4 described above.

[0094] <Proposal 2: Variation 1> The terminal may report the following terminal capabilities: • Ability to support gap / limit skipping instructions using DCI format 0_3 / 1_3 for simultaneously scheduled cells with interband CA and different SCSs • Ability to support gap / limit skipping instructions using DCI format 0_3 / 1_3 for simultaneously scheduled cells with interband CA and the same SCS • Ability to support gap / limit skipping instructions using DCI format 0_3 / 1_3 for simultaneously scheduled cells with intraband CA and different SCSs

[0095] <Proposal 2: Variation 2> Options 1 to 4 above assume, but are not limited to, that an explicit RRC parameter indicates the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3. In options 1 to 4 above, the parameter indicating the presence of a one-bit skipping instruction in DCI format 1_3 / 0_3 does not have to be used. In this case, signaling for the explicit RRC parameter can be reduced.

[0096] <Base Station Configuration> Figure 5 is a block diagram showing an example of the configuration of a base station 100 according to this embodiment. The base station 100 includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. The base station 100 communicates with a terminal 200 (see Figure 6) wirelessly.

[0097] The transmitting unit 101 transmits downlink (DL) signals to the terminal 200. For example, the transmitting unit 101 transmits DL signals (e.g., RRC, SIB, MAC CE, DCI, notification, confirmation, etc. as described above) under the control of the control unit 103.

[0098] The DL signal may include, for example, data signals for the downlink and control information (e.g., Downlink Control Information (DCI)). The DL signal may also include information indicating the scheduling of signal transmission by terminal 200 (e.g., UL grant). Furthermore, the DL signal may include control information from higher layers (e.g., Radio Resource Control (RRC) control information). Finally, the DL signal may include a reference signal.

[0099] The channels used to transmit DL signals include, for example, a downlink data channel and a downlink control channel. For example, the downlink data channel may include a PDSCH (Physical Downlink Shared Channel), and the downlink control channel may include a PDCCH (Physical Downlink Control Channel). For example, base station 100 transmits downlink control information to terminal 200 using the PDCCH and transmits downlink data signals using the PDSCH.

[0100] The reference signals included in the DL signal may include, for example, at least one of the following: Demodulation Reference Signal (DMRS), Phase Tracking Reference Signal (PTRS), Channel State Information-Reference Signal (CSI-RS), Sounding Reference Signal (SRS), and Positioning Reference Signal (PRS). For example, reference signals such as DMRS and PTRS are used for demodulating the downlink data signal and are transmitted using PDSCH.

[0101] The receiving unit 102 receives uplink (UL) signals transmitted from the terminal 200. For example, the receiving unit 102 receives UL signals (e.g., the requests and notifications mentioned above) under the control of the control unit 103.

[0102] The control unit 103 controls the communication operations of the base station 100, including the transmission process of the transmission unit 101 and the reception process of the reception unit 102. For example, the control unit 103 performs operations other than the transmission and reception described in the above embodiment (these operations may be performed by the reception unit 102 and / or the transmission unit 101).

[0103] For example, the control unit 103 acquires information such as data and control information from the upper layer and outputs it to the transmission unit 101. The control unit 103 also outputs the data and control information received from the receiving unit 102 to the upper layer.

[0104] For example, the control unit 103 allocates resources (or channels) used for transmitting and receiving DL signals and / or resources used for transmitting and receiving UL signals based on signals received from the terminal 200 (e.g., data and control information, etc.) and / or data and control information, etc. acquired from higher layers. Information regarding the allocated resources may be included in the control information transmitted to the terminal 200.

[0105] The control unit 103 sets the PUCCH resource as an example of resource allocation for sending and receiving UL signals. Information regarding PUCCH settings, such as the PUCCH cell timing pattern (PUCCH setting information), may be notified to the terminal 200 by RRC.

[0106] The control unit 103 may decide whether or not to include instruction information regarding instructions to skip measurements during measurement opportunities in the downlink control information used to simultaneously schedule multiple carriers. Measurement opportunities may be gap / limiting opportunities. Instruction information may be 1-bit instructions. Downlink control information may be in DCI format 0_3 / 1_3.

[0107] The transmitting unit 101 may transmit information indicating the decision result of the control unit 103, including it in higher-layer parameters such as RRC. The information may also be an explicit RRC setting.

[0108] <Terminal Configuration> Figure 6 is a block diagram showing an example of the configuration of a terminal 200 according to this embodiment. The terminal 200 includes, for example, a receiving unit 201, a transmitting unit 202, and a control unit 203. The terminal 200 communicates with, for example, a base station 100 wirelessly.

[0109] The terminal 200 includes, for example, a receiving unit 201, a transmitting unit 202, and a control unit 203. The terminal 200 communicates with, for example, a base station 100 wirelessly.

[0110] The receiving unit 201 receives DL signals transmitted from the base station 100. For example, the receiving unit 201 receives DL signals under the control of the control unit 203.

[0111] The transmitting unit 202 transmits the UL signal to the base station 100. For example, the transmitting unit 202 transmits the UL signal under the control of the control unit 203.

[0112] The UL signal may include, for example, data signals for the uplink and control information (e.g., UCI). It may also include, for example, information regarding the processing capability of terminal 200 (e.g., UE capability). Furthermore, the UL signal may include reference signals.

[0113] The channels used to transmit UL signals include, for example, a data channel and a control channel. For example, the data channel includes PUSCH (Physical Uplink Shared Channel), and the control channel includes PUCCH (Physical Uplink Control Channel). For example, terminal 200 receives control information from base station 100 using PUCCH and transmits uplink data signals using PUSCH.

[0114] The reference signals included in the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, reference signals such as DMRS and PTRS are used for demodulating the uplink data signal and are transmitted using an uplink channel (e.g., PUSCH).

[0115] The control unit 203 controls the communication operation of the terminal 200, including the receiving process in the receiving unit 201 and the transmission process in the transmitting unit 202.

[0116] For example, the control unit 203 acquires information such as data and control information from the upper layer and outputs it to the transmission unit 202. The control unit 203 also outputs data and control information received from the receiving unit 201 to the upper layer.

[0117] For example, the control unit 203 controls the transmission of information to be fed back to the base station 100. The information to be fed back to the base station 100 may include, for example, a HARQ-ACK, Channel State Information (CSI), or a Scheduling Request (SR). The information to be fed back to the base station 100 may be included in the UCI. The UCI is transmitted using the PUCCH resource.

[0118] The control unit 203 sets up PUCCH resources based on the configuration information received from the base station 100 (for example, configuration information such as the PUCCH cell timing pattern notified by RRC and / or DCI). The control unit 203 determines the PUCCH resource to be used to transmit the information to be fed back to the base station 100. The transmission unit 202 transmits the information to be fed back to the base station 100 using the PUCCH resource determined by the control unit 203, under the control of the control unit 203.

[0119] The channels used for transmitting DL signals and UL signals are not limited to the examples described above. For example, the channels used for transmitting DL signals and UL signals may include RACH (Random Access Channel) and PBCH (Physical Broadcast Channel). RACH may be used, for example, to transmit Downlink Control Information (DCI) including a Random Access Radio Network Temporary Identifier (RA-RNTI).

[0120] The receiving unit 201 receives information indicating whether instruction information regarding instructions to skip measurements during a measurement opportunity is included in the downlink control information used to simultaneously schedule multiple carriers. The measurement opportunity may be a gap / limit opportunity. The instruction information may be a 1-bit instruction. The downlink control information may be in DCI format 0_3 / 1_3.

[0121] The control unit 203 may determine whether or not instruction information is included in the downlink control information based on the information received by the receiving unit 201.

[0122] The control unit 203 may decide to ignore the instruction information included in the downlink control information if the simultaneously scheduled multicarriers have different SCSs and / or are in different frequency bands. The simultaneously scheduled multicarriers may be simultaneously scheduled cells. Multicarriers may be read as multicells.

[0123] This allows the terminal to operate correctly. For example, if multiple carriers scheduled simultaneously have different SCSs / are on different frequency bands, the terminal may ignore the instruction information contained in the downlink control information and operate in a way that does not skip gaps / limiting opportunities. In other words, the operation of the terminal when multiple carriers scheduled simultaneously have different SCSs / are on different frequency bands is clarified, and the terminal can operate correctly.

[0124] This concludes the explanation of this disclosure. The division of items in the above explanation is not essential to this disclosure, and matters described in two or more items may be combined as needed, and matters described in one item may be applied to matters described in another item (as long as they do not contradict each other).

[0125] <Hardware Configuration> The block diagram used in the description of the above embodiment shows functional units. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method of realizing each functional block is not particularly limited. That is, each functional block may be realized using one device that is physically or logically coupled, or it may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wired or wireless connections). A functional block may also be realized by combining the above one device or the above multiple devices with software.

For example, a functional block (configuration part) that enables transmission is called a transmitting unit or transmitter. In all cases, as mentioned above, the method of implementation is not particularly limited.

[0127] For example, a base station, terminal, etc. in one embodiment of the present disclosure may function as a computer that processes the wireless communication method of the present disclosure. Figure 7 is a diagram showing an example of the hardware configuration of a base station 100 and a terminal 200 according to an embodiment of the present disclosure.

The above-described various processes have been explained as being executed by one processor 1001, but they may be executed simultaneously or sequentially by two or more processors 1001. The processor 1001 may be implemented by one or more chips. The program may also be transmitted from the network via a telecommunications line.

Furthermore, notification of predetermined information (for example, notification that "it is X") is not limited to explicit notification, but may also be implicit (for example, by not providing notification of the predetermined information).

[0146] Although the present disclosure has been described in detail above, it will be clear to those skilled in the art that the present disclosure is not limited to the embodiments described herein. The present disclosure can be implemented in modified and altered forms without departing from the intent and scope of the present disclosure as defined by the claims. Therefore, the descriptions in the present disclosure are illustrative and not intended to be restrictive in any way.

[0148] Furthermore, software, instructions, information, etc., may be transmitted and received via a transmission medium. For example, if software is transmitted from a website, server, or other remote source using at least one of wired technology (such as coaxial cable, fiber optic cable, twisted pair, or digital subscriber line (DSL)) and wireless technology (such as infrared or microwave), then at least one of these wired and wireless technologies is included in the definition of a transmission medium.

[0152] <Parameters, Channel Names> Furthermore, the information, parameters, etc. described in this disclosure may be expressed using absolute values, relative values ​​from a predetermined value, or other corresponding information. For example, wireless resources may be indicated by an index.

[0153] The names used for the parameters described above are not restrictive in any way. Furthermore, the formulas and other expressions using these parameters may differ from those expressly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name, and therefore, the various names assigned to these various channels and information elements are not restrictive in any way.

[0154] <Base Station> In this disclosure, terms such as "Base Station (BS)", "wireless base station", "fixed station", "NodeB", "eNodeB (eNB)", "gNodeB (gNB)", "access point", "transmission point", "reception point", "transmission / reception point", "cell", "sector", "cell group", "carrier", and "component carrier" may be used interchangeably. Base stations may also be referred to by terms such as macrocell, small cell, femtocell, and picocell.

[0155] A base station can accommodate one or more (e.g., three) cells. If a base station accommodates multiple cells, the entire coverage area of ​​the base station can be divided into multiple smaller areas, each of which may also be provided with communication services by a base station subsystem (e.g., a Remote Radio Head (RRH)). The terms “cell” or “sector” refer to part or all of the coverage area of ​​at least one of the base station and / or base station subsystems that provide communication services in that coverage.

[0156] In this disclosure, the transmission of information by a base station to a terminal may be interpreted as the base station instructing the terminal to perform control or operation based on the information.

[0157] <Mobile Station> In this disclosure, terms such as "Mobile Station (MS)", "user terminal", "User Equipment (UE)", and "terminal" may be used interchangeably.

[0158] A mobile station may also be referred to by those skilled in the art as a subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, client, or several other appropriate terms.

[0159] <Base Station / Mobile Station> At least one of a base station and a mobile station may be called a transmitting device, a receiving device, a communication device, etc. At least one of a base station and a mobile station may be a device mounted on a mobile body, the mobile body itself, etc. The mobile body refers to a movable object, and its speed of movement is arbitrary.

Furthermore, at least one of the base station and the mobile station may include devices that do not necessarily move during communication operations. For example, at least one of the base station and the mobile station may be an IoT (Internet of Things) device such as a sensor.

[0160] Furthermore, the term "base station" in this disclosure may be interpreted as "terminal." For example, the various aspects / embodiments of this disclosure may be applied to a configuration in which communication between a base station and a terminal is replaced with communication between multiple terminals (which may be called, for example, D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). In this case, the terminal 200 may have the functions that the base station 100 has. Also, terms such as "uplink" and "downlink" may be interpreted as terms corresponding to terminal-to-terminal communication (for example, "side"). For example, uplink channel, downlink channel, etc., may be interpreted as side channel.

[0161] Similarly, the term "terminal" in this disclosure may be replaced with "base station." In this case, the base station 100 may be configured to have the same functions as the terminal 200 described above.

[0162] Figure 8 shows an example of the configuration of vehicle 2001. As shown in Figure 8, vehicle 2001 includes a drive unit 2002, a steering unit 2003, an accelerator pedal 2004, a brake pedal 2005, a shift lever 2006, front wheels 2007, rear wheels 2008, an axle 2009, an electronic control unit 2010, various sensors 2021 to 2029, an information service unit 2012, and a communication module 2013.

The driver assistance system unit 2030 also transmits and receives various information via the communication module 2013 to realize driver assistance functions or autonomous driving functions.

[0169] The communication module 2013 can communicate with the microprocessor 2031 and components of the vehicle 2001 via its communication port. For example, the communication module 2013 sends and receives data via the communication port 2033 between the drive unit 2002, steering unit 2003, accelerator pedal 2004, brake pedal 2005, shift lever 2006, front wheels 2007, rear wheels 2008, axle 2009, the microprocessor 2031 and memory (ROM, RAM) 2032 in the electronic control unit 2010, and sensors 2021-29 provided in the vehicle 2001.

[0170] The communication module 2013 is a communication device that can be controlled by the microprocessor 2031 of the electronic control unit 2010 and can communicate with external devices. For example, it can send and receive various types of information with external devices via wireless communication. The communication module 2013 may be located either inside or outside the electronic control unit 2010. The external device may be, for example, a base station or a mobile station.

[0171] The communication module 2013 may transmit at least one of the following to an external device via wireless communication: signals from the various sensors 2021 to 2029 input to the electronic control unit 2010, information obtained based on said signals, and information based on input from an external source (user) obtained via the information service unit 2012. The electronic control unit 2010, the various sensors 2021 to 2029, the information service unit 2012, etc., may also be called input units that accept input. For example, the PUSCH transmitted by the communication module 2013 may include the information based on the above input.

[0172] The communication module 2013 receives various information (traffic information, signal information, inter-vehicle information, etc.) transmitted from an external device and displays it on the information service unit 2012 provided in the vehicle 2001. The information service unit 2012 may also be called an output unit, which outputs information (for example, it outputs information to devices such as displays and speakers based on the PDSCH (or data / information decoded from the PDSCH) received by the communication module 2013).

[0173] Furthermore, the communication module 2013 stores various information received from external devices in a memory 2032 that can be used by the microprocessor 2031. Based on the information stored in the memory 2032, the microprocessor 2031 may control the drive unit 2002, steering unit 2003, accelerator pedal 2004, brake pedal 2005, shift lever 2006, front wheels 2007, rear wheels 2008, axles 2009, sensors 2021 to 2029, etc., which are provided in the vehicle 2001.

[0174] <Meaning and Interpretation of Terms> As used in this disclosure, the terms “determining” and “determining” may encompass a wide variety of actions. “Determining” may include, for example, judging, calculating, computing, processing, deriving, investigating, looking up, search, inquiry (e.g., searching in tables, databases or other data structures), and ascertaining. “Determining” may also include, for example, receiving (e.g., receiving information), transmitting (e.g., sending information), input, output, and accessing (e.g., accessing data in memory). Furthermore, "judgment" and "decision" can include considering something as having "judgmented" or "decided" after resolving, selecting, choosing, establishing, comparing, etc. In other words, "judgment" and "decision" can include considering something as having "judgmented" or "decided" about some action. Also, "judgment (decision)" can be reinterpreted as "assuming," "expecting," or "considering."

[0175] The terms “connected,” “coupled,” and any variations thereof mean any direct or indirect connection or coupling between two or more elements, and may include the presence of one or more intermediate elements between two elements that are “connected” or “coupled” with each other. The coupling or connection between elements may be physical, logical, or a combination thereof. For example, “connection” may be reinterpreted as “access.” As used in this disclosure, two elements may be considered to be “connected” or “coupled” with each other using at least one of one or more wires, cables, and printed electrical connections, and, in some non-limiting and non-exclusive examples, electromagnetic energy having wavelengths in the radio frequency domain, microwave domain, and optical (both visible and invisible) domain.

[0176] <Reference Signal> The reference signal can also be abbreviated as RS (Reference Signal), and may be called a pilot or pilot signal depending on the applicable standard.

[0177] <Meaning of "based on"> As used in this disclosure, the phrase "based on" does not mean "based solely on" unless otherwise specified. In other words, the phrase "based on" means both "based solely on" and "based at least on".

[0178] <"First", "Second"> Any reference to elements using the designations "first", "second", etc. as used in this disclosure does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient way to distinguish between two or more elements. Accordingly, references to first and second elements do not imply that only two elements may be adopted, or that the first element must precede the second element in any way.

[0179] <Means> The "means" in the configuration of each of the above devices may be replaced with "part," "circuit," "device," etc.

[0180] <Open Format> Where the terms “include,” “including,” and variations thereof are used in this disclosure, these terms are intended to be inclusive, as is the term “comprising.” Furthermore, the term “or” as used in this disclosure is not intended to be exclusive OR.

[0181] <Time units such as TTI, frequency units such as RB, and wireless frame configuration> A wireless frame may consist of one or more frames in the time domain. Each of the one or more frames in the time domain may be called a subframe. A subframe may further consist 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.

[0182] Numerology may be communication parameters applied to at least one of the transmission and reception of a signal or channel. Numerology may include, for example, at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration, specific filtering processes performed by the transceiver in the frequency domain, and specific windowing processes performed by the transceiver in the time domain.

[0183] A slot may consist of one or more symbols in the time domain (such as OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A slot may also be a time unit based on neurology.

[0184] A slot may include multiple minislots. Each minislot may consist of one or more symbols in the time domain. Minislots may also be called subslots. Minislots may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called a PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called a PDSCH (or PUSCH) mapping type B.

[0185] Wireless frames, subframes, slots, minislots, and symbols all represent units of time when transmitting a signal. Different names may be used for each of these terms.

[0186] For example, one subframe may be called a Transmission Time Interval (TTI), multiple consecutive subframes may be called a TTI, or one slot or one minislot may be called a TTI. In other words, at least one of a subframe and a TTI may be a subframe in existing LTE (1 ms), a period shorter than 1 ms (e.g., 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.

[0187] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, the base station schedules each user terminal to allocate wireless resources (such as the frequency bandwidth and transmission power available to each user terminal) in TTI units. However, the definition of TTI is not limited to this.

[0188] TTI may be a transmission time unit for channel-encoded data packets (transport blocks), code blocks, code words, etc., or it may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the actual time interval (e.g., number of symbols) in which the transport block, code block, code word, etc. are mapped may be shorter than the TTI.

[0189] Furthermore, if one slot or one mini-slot is referred to as a TTI, then one or more TTIs (i.e., one or more slots or one or more mini-slots) may constitute the minimum time unit for scheduling. In addition, the number of slots (number of mini-slots) that constitute this minimum time unit for scheduling may be controlled.

[0190] A TTI with a time length of 1 ms may be called a normal TTI, a long TTI, a normal subframe, a long subframe, a slot, etc. A TTI shorter than a normal TTI may be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a mini slot, a sub slot, a slot, etc.

[0191] Furthermore, long TTIs (e.g., normal TTIs, subframes, etc.) may be interpreted as TTIs with a time length exceeding 1 ms, and short TTIs (e.g., shortened TTIs, etc.) may be interpreted as TTIs with a TTI length less than that of a long TTI but 1 ms or more.

[0192] A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and in the frequency domain, it may contain one or more consecutive subcarriers. The number of subcarriers in an RB may be the same regardless of the neurology, for example, 12. The number of subcarriers in an RB may be determined based on the neurology.

[0193] Furthermore, the time domain of the RB may contain one or more symbols and may be the length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc., may each consist of one or more resource blocks.

[0194] One or more RBs may also be called a Physical RB (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB pair, RB pair, etc.

[0195] Furthermore, a resource block may consist of one or more resource elements (REs). For example, one RE may be a radio resource area comprising one subcarrier and one symbol.

[0196] A Bandwidth Part (BWP), also known as a partial bandwidth, may represent a subset of consecutive common resource blocks (RBs) for a given neurology in a given carrier. These common RBs may be identified by an index of the RBs relative to a common reference point of the carrier. The PRBs may be defined and numbered within a given BWP.

[0197] A BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be set within a single carrier for a UE.

[0198] At least one of the configured BWPs may be active, and the UE does not need to assume that it will transmit or receive a predetermined signal / channel outside of the active BWP. In this disclosure, terms such as "cell" and "carrier" may be read as "BWP".

[0199] The structures described above, such as wireless frames, subframes, slots, minislots, and symbols, are merely illustrative. For example, the number of subframes included in a wireless frame, the number of slots per subframe or wireless 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, and the number of symbols, symbol length, and cyclic prefix (CP) length within a TTI can be varied in various ways.

[0200] <Maximum Transmit Power> The term "maximum transmit power" as used in this disclosure may mean the maximum value of the transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0201] <Articles> In this disclosure, if articles are added by translation, such as a, an, and the in English, this disclosure may also include the fact that the noun following these articles is plural.

[0202] <"Different"> In this 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 "combine" may be interpreted similarly to "different."
