Description

Technical Field

[0001] This disclosure relates to terminals and communication methods. Background Technology

[0002] The 3rd Generation Partnership Project (3GPP) is advancing the standardization of the 5th generation mobile communication system (also known as 5G, New Radio (NR) or Next Generation (NG)) and further advancing the standardization of the next generation, known as Beyond 5G, 5G Evolution or 6G.

[0003] In 5G, as a requirement, research is conducted on technologies that meet the requirements of large-capacity systems, high-speed data transmission, low latency, simultaneous connection of a large number of terminals, low cost, and power saving (e.g., non-patent literature 1).

[0004] With the enhancement of mobile communication systems as described above, the combination of the real world and the virtual world (virtual content) is made possible. The utilization and popularization of XR (extended reality) such as VR (virtual reality), AR (augmented reality), and MR (mixed reality) are expected. In 3GPP, XR enhancement is discussed in Release 19 (for example, see Non-Patent Literature 2).

[0005] Regarding XR enhancement, for example, there is extensive discussion of enhancements related to measurement gap (MG) and scheduling constraints.

[0006] For example, scheduling constraints related to inter-frequency RRM measurements of FR1 and FR2 with accompanying measurement gaps, and intra-frequency RRM measurements of FR2 without accompanying measurement gaps, and the determination of enhancements to reduce the impact on capacity and individual terminals, may be included in the scope of the standard in the future.

[0010] Non-patent literature 2: “Moderator's summary for REL-19 RAN2 topic Enhancements for XR”, RP-232619, 3GPP TSG-RAN Meeting #101, 3GPP, September 2023 Summary of the Invention

[0011] In existing wireless communication systems, measurements using synchronization signal blocks (SSB) are employed (SSB-based measurement).

[0012] For SSB measurements, measurement-related timing settings (SMTC: SSB-based Measurement Timing Configuration) are communicated to the terminal. The terminal then performs measurements based on the signal of the object being measured within the configured SMTC window. Furthermore, settings related to measurement intervals can be communicated to the terminal for SSB measurements, such as for switching operating frequencies (RF: Radio Frequency).

[0013] In cases where the periodicity of XR traffic causes overlap with the transmission and reception of signals involved in the SMTC window, measurement gaps, and XR traffic, problems such as the inability to schedule the signal and capacity loss due to scheduling limitations associated with the measurement may occur.

[0014] Furthermore, in existing wireless communication systems, other measurements, such as those using Channel State Information Reference Signal (CSI-RS) (CSI-RS based measurement), also utilize this problem, and the aforementioned issues may occur in various other measurements as well. Moreover, these problems may also occur when transmitting and receiving signals other than those involved in XR traffic.

[0015] One aspect of this disclosure provides a terminal and a communication method capable of reducing the impact of measurement-related scheduling constraints.

[0016] One aspect of this disclosure relates to a terminal comprising: a control unit that determines whether to receive or transmit the signal or to perform a measurement using the measurement signal when the timing of receiving or transmitting the signal overlaps with a period associated with a measurement using the measurement signal; and a communication unit that receives or transmits the signal at the timing based on the determination.

[0046] Hereinafter, an embodiment of one aspect of this disclosure will be described with reference to the accompanying drawings.

[0047] (Implementation Method)

[0048] <Wireless Communication Systems>

[0049] Figure 1 This is a diagram illustrating an example of a wireless communication system 10 according to an embodiment of the present disclosure. The wireless communication system 10 is a 5G NR compliant wireless communication system, including a next-generation radio access network 20 (hereinafter NG-RAN 20) and a terminal 200 (hereinafter also referred to as UE (User Equipment) 200).

[0050] Alternatively, the wireless communication system 10 may also be a wireless communication system that follows a protocol called Beyond 5G, 5G Evolution, or 6G.

[0051] NG-RAN20 includes base station 100A (hereinafter also referred to as gNB100A) and base station 100B (hereinafter also referred to as gNB100B). However, 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 [specific number missing]. Figure 1 The example shown.

[0052] NG-RAN20 actually comprises multiple NG-RAN nodes, specifically gNBs (or ng-eNBs), and connects to a 5G-compliant core network (5GC, not shown). Additionally, NG-RAN20 and 5GC can also be simply referred to as "network". Furthermore, gNB can also be rewritten as network (NW) below.

[0053] As an example, gNB100A and gNB100B are 5G-compliant base stations that perform 5G-compliant wireless communication with UE200. gNB100A, gNB100B, and UE200 can also support MIMO (Multiple-Input Multiple-Output) which generates more directional beams by controlling wireless signals transmitted from multiple antenna elements, carrier aggregation (CA) which aggregates multiple component carriers (CC), and dual connectivity (DC) which allows communication between the UE and each of the two NG-RAN nodes.

[0054] In addition, the wireless communication system 10 can also support multiple frequency ranges (FRs). Figure 2 This is a diagram illustrating an example of the FR used in the wireless communication system 10. (As shown) Figure 2 As shown, the wireless communication system 10 can also support FR1 and FR2. The frequency bands of each FR are as follows.

[0055] FR1: 410MHz~7.125GHz

[0056] FR2: 24.25GHz~52.6GHz

[0057] In FR1, sub-carrier spacing (SCS) of 15kHz, 30kHz, or 60kHz can be used, as well as a bandwidth (BW) of 5~100MHz. FR2 is a higher frequency than FR1, and can also use SCS of 60kHz or 120kHz (including 240kHz), and a bandwidth (BW) of 50~400MHz.

[0058] Alternatively, SCS can also be interpreted as a parameter set (numerology). The parameter set is defined in 3GPP TS 38.300 and corresponds to a subcarrier spacing in the frequency domain.

[0059] Furthermore, the wireless communication system 10 can also support frequency bands higher than FR2. Specifically, the wireless communication system 10 can also support frequency bands from 52.6 GHz to 114.25 GHz. For convenience, such high-frequency bands can also be referred to as "FR2x". When using a band domain 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 can also be applied.

[0060] Figure 3 This is a diagram illustrating an example of the structure of radio frames (system frames), subframes, and time slots used in a wireless communication system 10. (See diagram below.) Figure 3 As shown, one time slot consists of 14 symbols. The larger the SCS, the shorter the symbol period (and time slot period). However, the SCS is not limited to a certain value. Figure 3 The intervals (frequency) shown. For example, as an SCS, 480kHz, 960kHz, etc. can also be used.

[0061] Furthermore, the number of symbols constituting one time slot is not necessarily 14 symbols (for example, it could be 28 or 56 symbols, etc.). Moreover, the number of time slots in each subframe can also vary depending on the SCS.

[0062] in addition, Figure 3 The time direction (t) shown can also be referred to as the time domain, symbol period, or symbol time, etc. Furthermore, the frequency direction can also be referred to as the frequency domain, resource block, subcarrier, bandwidth part (BWP), etc.

[0063] As a downlink (DL) signal, gNB100 sends control information, configuration information, etc. to UE200.

[0064] In addition, for example, as an uplink (UL) signal, gNB100 receives control information, data signals, and information related to the processing capabilities of UE200 (terminal capability (information); for example, UE capability) from UE200.

[0065] The channels used in DL signal transmission include, for example, data channels and control channels. For instance, 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 uses PDCCH to transmit control information and PDSCH to transmit DL data signals to UE200. Furthermore, PDSCH is an example of a downlink shared channel, and PDCCH is an example of a downlink control channel. Additionally, PDCCH can be rewritten to transmit downlink control information (DCI), control information, etc.

[0066] The reference signals included in the DL signal may include 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 location information. For example, reference signals such as DMRS and PTRS are used for demodulating the DL data signal and are transmitted using PDSCH.

[0067] UE200 is a communication device with wireless communication capabilities, such as smartphones, mobile phones, tablets, wearable terminals, and M2M (machine-to-machine) communication modules.

[0068] UE200 receives control signals or data signals from gNB100 via DL and transmits control signals or data signals to gNB100 via UL, thereby utilizing various communication services provided by wireless communication system 10. Furthermore, UE200 receives various reference signals transmitted from gNB100 and performs propagation path quality measurements based on the reception results of these reference signals.

[0069] For example, as a DL signal, UE200 receives control information, setting information, etc. from gNB100.

[0070] In addition, for example, as a UL signal, UE200 sends control information, data signals, and UE200 terminal capability information to gNB100.

[0071] The channels used in transmitting UL signals include, for example, data channels and control channels. For instance, a data channel may include a Physical Uplink Shared Channel (PUSCH), and a control channel may include a Physical Uplink Control Channel (PUCCH). For example, UE200 uses PUCCH to transmit control information and PUSCH to transmit UL data signals. Furthermore, PUSCH is an example of an uplink shared channel, and PUCCH is an example of an uplink control channel. Additionally, PUSCH or PUCCH can be rewritten to transmit uplink control information (UCI), control information, etc., within PUSCH or PUCCH.

[0072] The reference signals included in UL signals may include 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 for demodulation of UL data signals and are transmitted using PUSCH.

[0073] <State of discussion related to XR>

[0074] XR offers attractive use cases for future wireless communication systems. On the other hand, XR also presents challenges that need to be studied and addressed. As one of these challenges, XR enhancements are being discussed in 3GPP toward Release 19 (e.g., see Non-Patent Literature 2), with extensive discussions on enhancements related to measurement gaps and scheduling constraints.

[0075] <About SSB and SSB Measurement>

[0076] Some of the signals and / or channels transmitted from the base station to the terminal are transmitted periodically. Examples of such signals and / or channels include the Synchronization Signal Block (SSB).

[0077] SSB is a measurement performed by the terminal for, for example, received power (e.g., SS-RSRP (Synchronization Signal Reference Signal Received Power)) and received quality (e.g., SS-RSRQ (Synchronization Signal Reference Signal Received Quality)). This measurement is an example of RRM (Radio Resource Management) measurement.

[0078] For SSB measurements, a measurement-related timing setting (SMTC) is provided to the terminal. The SMTC may include the length, period, and timing offset of the SSB measurement period (also known as the SMTC window, measurement timing, etc.). Within the configured SMTC window, the terminal performs measurements based on the signal of the object being measured.

[0079] Furthermore, to switch operating frequencies (RF: Radio Frequency), settings related to the measurement gap can be communicated to the terminal for SSB measurements. The measurement gap is an extended period that can be appended before and after the SMTC window for measurement purposes. Settings related to the measurement gap can also include length, period, etc.

[0080] In addition, examples of RRM measurements also include CSI-RS-based measurements (CSI-RS measurements).

[0081] In NR, the following RRM measurements are used, including SSB measurements and CSI-RS measurements, with or without a measurement gap.

[0082] (1) Measurement at the same frequency or within the same frequency range (Intra-frequency measurement)

[0083] (2) Measurement at different frequencies or between frequencies

[0084] The terminal can use at least one of the first frequency band (FR1) and the second frequency band (FR2) to perform the above-mentioned RRM measurement and signal transmission and reception.

[0085] <Scheduling constraints related to RRM measurements>

[0086] Regarding in-frequency SSB measurements, existing standards document scheduling restrictions (terminal operation restrictions) related to in-frequency SSB measurements without measurement gaps, in-frequency SSB measurements with NCSG (Network Configured Small Gap), and in-frequency SSB measurements with measurement gaps in the following locations.

[0087] SSB measurements within a frequency range without a measurement gap: TS 38.133 clause 9.2.5.3 (In short, under certain conditions, scheduling restrictions are imposed on SSB symbols or all symbols within the SMTC window that are measured within the SMTC window).

[0088] SSB measurement within the frequency range accompanying the NCSG: TS 38.133 Clause 9.2.5.3

[0089] SSB measurement within the frequency range accompanying the measurement gap: TS 38.133 Clause 9.1.2

[0090] Regarding inter-frequency SSB measurements, existing standards specify scheduling restrictions (terminal operation restrictions) related to inter-frequency SSB measurements without measurement gaps, inter-frequency SSB measurements with NCSG, and inter-frequency SSB measurements with measurement gaps in the following locations.

[0091] Inter-frequency SSB measurements without measurement gaps: TS 38.133 clause 9.3.5.3 (In short, under certain conditions, scheduling restrictions are imposed on SSB symbols or all symbols within the SMTC window that are measured within the SMTC window).

[0092] Inter-frequency SSB measurements accompanying NCSG: Clause 9.2.10.3 of TS 38.133 (in short, under certain conditions, a scheduling constraint is imposed on the union of SSB symbols measured within an SMTC window for all measurement opportunities (MOs) or the union of all symbols within an SMTC window for all MOs).

[0093] Inter-frequency SSB measurement accompanying the measurement gap: TS 38.133 clause 9.1.2

[0094] Regarding in-frequency CSI-RS measurements, existing standards specify scheduling constraints (terminal operation constraints) related to in-frequency CSI-RS measurements without measurement gaps in the following locations.

[0095] CSI-RS measurements within frequencies without measurement gaps: TS 38.133 clause 9.10.2.6 (In short, scheduling restrictions are imposed on the set CSI-RS symbols under certain conditions).

[0096] Regarding inter-frequency CSI-RS measurements, existing standards specify the scheduling constraints (terminal operation constraints) associated with inter-frequency CSI-RS measurements during the accompanying measurement intervals in the following locations.

[0097] Inter-frequency CSI-RS measurements accompanying measurement gaps: TS 38.133 Clause 9.1.2

[0098] When the periodicity of XR traffic causes the SMTC window, measurement gap, and signal transmission and reception involved in the XR traffic to overlap, problems such as the inability to schedule the signal and capacity loss due to scheduling limitations associated with the measurement may occur.

[0099] However, the terminal also performs measurements for wireless link monitoring, L1-RSRP, beam failure detection, and other purposes.

[0100] The aforementioned problems may also occur in CSI-RS measurements and the wide variety of measurements that include them. Furthermore, these problems may also occur with the transmission and reception of signals other than those involved in XR traffic.

[0101] Currently, although extensions (enhancements) for scheduling constraints are being studied, research on the specific operations related to the control used to implement these extensions is insufficient.

[0102] Therefore, the following is an explanation of a proposal to reduce the impact of measurement-related scheduling constraints (a proposal to mitigate measurement-related scheduling constraints).

[0103] More specifically, this proposal includes the following proposals 1 through 5.

[0104] Proposal 1: Support terminal-based prioritization of channel / signal transmission / reception over RRM measurements based on one or more conditions.

[0105] Proposal 2: Support notifications from base stations to skip or deactivate measurement gaps.

[0106] Proposal 3: Support reporting of terminal-based requests / notifications to skip or deactivate measurement gaps.

[0107] Proposal 4: Support periodic / semi-continuous / non-periodic measurement gaps

[0108] Proposal 5: Support notifications from base stations to skip or deactivate RRM measurements.

[0109] Proposal 6: Support reporting of requests / notifications made by the terminal to skip or deactivate RRM measurements.

[0110] The following explanation, for proposals 1-3, assumes that the measurement gap is periodic. For example, the measurement gap (setting) can also be set using an existing measurement gap setting information element (e.g., MeasGapConfig IE) as an RRC parameter, or a (new) information element that is the same as that information element. The period of the measurement gap can also be set in such an information element.

[0111] Proposals 1, 5, and 6 can also be applied to any measurement (e.g., RRM measurement) including and / or not including measurement gaps, intra-frequency SSB and / or CSI-RS measurements, and / or inter-frequency SSB and / or CSI-RS measurements. On the other hand, Proposals 2, 3, and 4 can only be applied to intra-frequency SSB and / or CSI-RS measurements and / or inter-frequency SSB and / or CSI-RS measurements with measurement gaps.

[0112] In addition, the matters described in Proposals 1 to 6 can be appropriately combined as long as they do not contradict each other.

[0113] In this application, the word " / " can also mean "and / or" unless otherwise specified.

[0114] Furthermore, in this application, the expression "not receiving / sending" can also be rewritten as "not assuming receiving / sending", "unable to receive / send", "not performing receiving / sending", "restricting receiving / sending", "assuming unable to receive / send", etc.

[0115] In addition, in this application, the expression "deactivate" can also be rewritten as "disable", "off", "become invalid (disabled state, off state)", etc., and "activate" can also be rewritten as "enable", "on", "become valid (disabled state, off state)", etc.

[0116] Furthermore, in this application, the term "notification" can also be rewritten as "instruction".

[0117] Furthermore, in this application, signals used for measuring received power, received quality, etc., such as SSB and CSI-RS, may also be referred to as measurement signals or measurement signals.

[0118] Furthermore, in this application, "skip or deactivate ~" can also be understood as "in ~, no measurement (e.g., RRM measurement) is performed", "it is assumed that no scheduling constraints are applied in ~ (it is not assumed that scheduling constraints are applied)", etc.

[0119] <Proposal 1>

[0120] The following describes the support performed by the terminal for prioritizing channel / signal transmission / reception over RRM measurement based on one or more conditions (Proposal 1). Processes related to prioritizing channel / signal transmission / reception over RRM measurement and / or prioritizing either RRM measurement or channel / signal transmission / reception can also be referred to as priority processing, etc.

[0121] One or more conditions used to prioritize channel / signal transmission / reception over RRM measurements can also follow options 1 / 2 below.

[0122] [Option 1]

[0123] One or more conditions can also be predefined conditions. For example, a predefined rule as a predefined condition can define when and what kind of signal / channel (transmission / reception) can take precedence over RRM measurements (with or without measurement gaps). Such conditions / rules can also be predefined in a standard. In Option 1, Terminal 200 can also decide, based on predefined conditions (e.g., during a measurement gap / SMTC window), whether to perform DL / UL channel / signal reception / transmission or to perform RRM measurements.

[0124] As an example of Option 1, if there is a DL / UL channel / signal being received / transmitted on one or more CCs, and the DL / UL channel / signal overlaps with the measurement gap, or overlaps with the SMTC window (the SSB symbol for in-measuring), or overlaps with the CSI-RS symbol for RRM measurement, and one or more of the following conditions A1 to A9 are met, the terminal 200 performs the reception / transmission of the DL / UL channel / signal, and (e.g., during the measurement gap / SMTC window) does not perform RRM measurement.

[0125] Condition A1: The DL / UL channel / signal is a specific channel / signal type (e.g., PDCCH / PDSCH / CSI-RS / PUCCH / PUSCH / SRS (Sounding Reference Signal) etc.).

[0126] Condition A2: The DL / UL channel / signal is scheduled / triggered via DCI (or activated via DCI, or set via RRC), or scheduled / triggered via a specific DCI format.

[0127] Condition A3: The DL / UL channel / signal has a low physical layer priority value (“0”) / a high physical layer priority value (“1”) (introduced in Release 16).

[0128] Condition A4: The DL / UL channel / signal is aperiodic / semi-persistent / periodic.

[0129] Condition A5: DL / UL channels / signals are used for specific service types (e.g., for XR / for URLLC / for eMBB, etc.).

[0130] Condition A6: Communication is performed in a specific scenario (e.g., in TN / NTN, in FR1 / FR2, in licensed bands, in unlicensed bands, in FDD / TDD, etc.).

[0131] Condition A7: RRM measurement with or without measurement gap.

[0132] Condition A8: RRM measurement or measurement gap is used for intra-frequency measurement or inter-frequency measurement.

[0133] Condition A9: RRM measurement is based on SSB measurement or CSI-RS measurement.

[0134] Conversely, in cases other than those described above, terminal 200 (e.g., during a measurement gap / SMTC window) performs RRM measurements without receiving / transmitting DL / UL channels / signals.

[0135] Figure 4 An example is shown that satisfies condition A5 among conditions A1 to A9. For example... Figure 4 As shown, when the PDSCH scheduled via DCI is used for URLLC / XR (URLLC / XR PDSCH), and condition A5 is specifically "DL / UL channel / signal used for URLLC / XR", terminal 200 receives URLLC / XR PDSCH and does not measure SSB during the measurement gap / SMTC window.

[0136] [A variation of the example in option 1]

[0137] The aforementioned one or more CCs (or carriers) can be defined by a standard (e.g., Pcell (primary cell) / Pscell (primary / secondary cell) / Scell ​​(secondary cell)), set by RRC (e.g., a list of CCs can be set, or each CC can be activated / deactivated first), or one or more CCs in a specific frequency range (e.g., FR1 / FR2).

[0138] [Option 2]

[0139] One or more conditions can also be based on a priority state value or priority value. A priority state value or priority value (hereinafter simply referred to as a priority state value) can also be referred to as information or a value representing priority or order of precedence. In option 2, terminal 200 can also determine (e.g., in a measurement gap / SMTC window) whether to prioritize the transmission / reception of the DL / UL channel / signal or the RRM measurement based on the priority state value of the DL / UL channel / signal and / or RRM measurement.

[0140] As an example of Option 2 (Example 1), Terminal 200 can also determine whether to prioritize the transmission / reception of the DL / UL channel / signal or the RRM measurement based on the priority status value of the DL / UL channel / signal and the measurement gap. More specifically, if there is a DL / UL channel / signal being received / transmitted on more than one CC, and the DL / UL channel / signal overlaps with the measurement gap, and the priority status value of the DL / UL channel / signal is greater than (or less than) the priority status value of the measurement gap, Terminal 200 performs the reception / transmission of the DL / UL channel / signal without performing RRM measurement during the measurement gap. Otherwise, Terminal 200 performs or needs to perform RRM measurement during the measurement gap without receiving / transmitting the DL / UL channel / signal.

[0141] As another example of Option 2 (Example 2), Terminal 200 can also decide whether to prioritize the transmission / reception of the DL / UL channel / signal or the RRM measurement based on the priority status value of the DL / UL channel / signal and the RRM measurement. More specifically, if a DL / UL channel / signal exists on more than one CC, and the DL / UL channel / signal overlaps with the SMTC window (the SSB symbol measured within the window), or overlaps with the CSI-RS symbol measured for RRM measurement, and the priority status value of the DL / UL channel / signal is greater than (or less than) the priority status value of the RRM measurement, Terminal 200 performs the reception / transmission of the DL / UL channel / signal without performing the RRM measurement. Otherwise, Terminal 200 performs or needs to perform the RRM measurement without receiving / transmitting the DL / UL channel / signal.

[0142] Figure 5 This illustrates an example of how priority status values ​​based on DL / UL channel / signal and RRM measurements determine whether to prioritize DL / UL channel / signal transmission / reception or RRM measurements. For example... Figure 5 As shown, when the URLLC / XR PDSCH scheduled by DCI has a priority status value of "0" (high priority status value) and the RRM measurement has a priority status value of "1" (low priority status value), the terminal 200 receives the URLLC / XR PDSCH and does not measure the SSB in the measurement gap / SMTC window.

[0143] Figure 6 This illustrates another example of how priority status values ​​based on DL / UL channel / signal and RRM measurements determine whether to prioritize DL / UL channel / signal transmission / reception or RRM measurements. For example... Figure 6 As shown, when the URLLC / XRPDSCH scheduled by DCI has a priority status value "1" (low priority status value) and the RRM measurement has a priority status value "0" (high priority status value), the terminal 200 does not receive the URLLC / XRPDSCH and measures the SSB during the measurement gap / SMTC window.

[0144] Furthermore, the priority status values ​​for DL / UL channels / signals and / or RRM measurements and / or measurement intervals can also be determined by standard definitions (e.g., priority status value X for a certain channel / signal), and / or by notifications from base station 100 (e.g., RRC setting / DCI notification / MAC CE notification), and / or by the capabilities of terminal 200 (UE capability). When the priority status values ​​are determined by standard definitions, different priority status values ​​can be defined for different conditions A1 / A2 / A3 / A4 / A5 as presented in the example of Option 1 above. For example, priority status values ​​can also be defined for each condition.

[0145] [A variation of the example in option 2]

[0146] For the examples above (Example 1 and Example 2), one or more CCs (or carriers) can also be defined by a standard (e.g., Pcell / Pscell / Scell), set by RRC (e.g., a list of CCs can be set, and priority can be given to activate / deactivate each CC), or one or more CCs in a specific frequency range (e.g., FR1 / FR2).

[0147] [A variation of Proposal 1]

[0148] Whether to prioritize activation can be defined by standards (e.g., always active (valid state)), set by RRC, or determined based on the capabilities of terminal 200.

[0149] Proposal 1 can also be applied to intra-frequency SSB / CSI-RS measurements / inter-frequency SSB / CSI-RS measurements with or without measurement gaps.

[0150] In addition, in this application, measurement gaps, SMTC windows, SSB symbols, CSI-RS symbols, etc., can also be referred to as periods or intervals associated with measurements.

[0151] <Operation example>

[0152] Next, refer to Figure 20 An example of operating the terminal 200 is explained.

[0153] In step S11, the terminal 200 determines whether to receive or transmit a signal ( / channel) or to perform a measurement using a measurement signal when the timing of receiving or transmitting the signal ( / channel) overlaps with the period associated with the measurement using the measurement signal.

[0154] In step S12, the terminal 200 follows the determination in step S11 and receives or sends a signal ( / channel) at the aforementioned timing.

[0155] As described above, the processing in steps S11 and S12 can also be understood as equivalent to prioritizing the transmission / reception of the channel / signal over RRM measurement based on one or more certain conditions.

[0156] According to Proposal 1, it is possible to prioritize channel / signal transmission / reception over RRM measurements based on conditions, thereby reducing the impact of scheduling constraints related to measurements.

[0157] <Proposal 2>

[0158] As Proposal 2, it describes support for notifications made by the base station to skip or deactivate measurement gaps.

[0159] The operation of terminal 200 related to skipping or deactivating measurement gaps can also be based on notifications from base station 100.

[0160] For example, if terminal 200 is notified from base station 100 to skip or deactivate a measurement gap opportunity, terminal 200 may also receive / transmit DL / UL channels / signals during the measurement gap opportunity instead of performing RRM measurements (and / or positioning reference signal (PRS) measurements) during the measurement gap opportunity.

[0161] Skipping or deactivating measurement gap opportunities can also be notified by following Alt 1 / 2.

[0162] [Alt 1]

[0163] Skipping or deactivating measurement gap opportunities can also be notified via semi-static notifications based on RRC or SIB. For example, a measurement gap skipping pattern can be set by RRC, or a measurement gap skipping pattern can be notified by SIB. In the case of multiple measurement gap settings, the measurement gap skipping pattern can be common to all measurement gap settings, or it can be set / notified for each measurement gap setting. Semi-static notifications based on RRC or SIB can also be referred to as information indicating that a measurement will not be performed (during a period of periodic extension for measurement). Terminal 200 can also be notified of skipping or deactivating measurement gap opportunities by receiving such semi-static notifications from base station 100, and can also determine which measurement gap opportunities to skip and / or not to skip based on such semi-static notifications.

[0164] Measurement gaps that are set / notified to be non-skipped will not be skipped. Terminal 200 needs to perform RRM measurements during these non-skipped measurement gaps, applying scheduling constraints defined in existing standards. Alternatively, during measurement gaps that are set / notified to be skipped, terminal 200 may not perform RRM measurements but instead receive / transmit DL / UL channels / signals.

[0165] Figure 7 An example of a notification skipping measurement gap opportunity based on Alt 1 is shown. Figure 7 As shown, when the measurement gap skipping mode is set to "Not skip / enable", "Skip / disable", "Not skip / activate", and "Not skip / activate", the first measurement gap opportunity in the illustrated measurement gap opportunities is set to not skip (activate), the second measurement gap opportunity is set to skip (disactivate), the third measurement gap opportunity is set to not skip (activate), and the fourth measurement gap opportunity is set to not skip (activate). Therefore, terminal 200 can also decide to skip the second measurement gap opportunity, and terminal 200 can also receive / transmit DL / UL channels / signals without performing RRM measurement in the second measurement gap.

[0166] [Alt 2]

[0167] The skipping or deactivation of measurement gap opportunities can also be notified via dynamic notification based on DCI or MAC CE. Dynamic notification based on DCI or MAC CE can also be referred to as information indicating that a measurement will not be performed (during a periodic extension for measurement). Terminal 200 can also be notified of the skipping or deactivation of measurement gap opportunities by receiving this dynamic notification from base station 100, and can also determine which measurement gap opportunities to skip and which not to skip based on this dynamic notification. Dynamic notification based on DCI or MAC CE can also follow the following Alt 2-1 / 2-2 / 2-3 / 2-4.

[0168] ·Alt 2-1

[0169] DCI or MAC CE can also notify the skipping of N consecutive measurement gap opportunities (N is an integer greater than 1).

[0170] As an example of Alt 2-1, the initial measurement gap opportunity to be skipped is the initial measurement gap opportunity after the X symbol / slot of the final symbol / slot of the DCI used for notification (or, for the HARQ-ACK of the PDSCH corresponding to (or containing) the MAC CE used for notification). Thus, terminal 200 can also determine the initial measurement gap opportunity to skip based on the DCI / MAC CE. The value of X can also be defined by a standard, set by RRC, or notified via the DCI / MAC CE used for notification.

[0171] In addition, the value of N can be defined by a standard (e.g., N=1), set by RRC, or notified via DCI / MAC CE.

[0172] Measurement gap opportunities not included in N consecutive measurement gap opportunities are not skipped. Terminal 200 needs to perform RRM measurements during the non-skipped measurement gap opportunities, and apply the scheduling constraints defined in the existing standard during these non-skipped measurement gap opportunities. Alternatively, terminal 200 may receive / transmit DL / UL channels / signals without performing RRM measurements during the N consecutive measurement gap opportunities.

[0173] Figure 8 This illustrates an example of skipping measurement gap opportunities based on Alt 2-1, specifically, skipping N (in...) via DCI notification. Figure 8The example shown is an example of consecutive measurement gap opportunities (N=2). In this example, the initial measurement gap opportunity and the second measurement gap opportunity illustrated are skipped. Therefore, terminal 200 can also decide to skip the initial measurement gap opportunity and the second measurement gap opportunity illustrated, and not perform RRM measurements during these measurement gap opportunities, but instead receive / transmit DL / UL channels / signals.

[0174] ·Alt 2-2

[0175] DCI or MAC CE can also notify the skipping of measurement gap opportunities within a skipping window. The skipping window can also be referred to as a measurement non-execution period, a period during which measurements are not performed, etc.

[0176] As an example of Alt 2-2, the start of the skip window can also be after the X symbol / slot of the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK for the PDSCH corresponding to the MAC CE used for the notification). In this way, terminal 200 can also determine the start of the skip window based on the DCI / MAC CE. The value of X can also be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0177] In addition, the length of the skip window can be defined by a standard, set by RRC, or notified via DCI / MAC CE.

[0178] Measurement gaps not included in the skip window will not be skipped. Terminal 200 needs to perform RRM measurements during these non-skipped measurement gaps, applying scheduling constraints defined in existing standards. During measurement gaps included in the skip window, terminal 200 may also receive / transmit DL / UL channels / signals without performing RRM measurements.

[0179] Figure 9 An example of skipping measurement gap opportunities based on Alt 2-2 is shown, specifically an example of skipping measurement gap opportunities included in the skip window by DCI notification. In this example, the initial measurement gap opportunity and the second measurement gap opportunity illustrated are skipped. Therefore, terminal 200 can also decide to skip the initial measurement gap opportunity and the second measurement gap opportunity illustrated, and not perform RRM measurements during these measurement gap opportunities, but instead receive / transmit DL / UL channels / signals.

[0180] Alt 2-3

[0181] DCI or MAC CE can also notify whether to skip or not skip each of N consecutive measurement gap opportunities (N is an integer greater than 1).

[0182] As an example of Alt 2-3, DCI or MAC CE can also notify (or include) a bitmap in which each bit indicates whether to skip or not skip the corresponding measurement gap opportunity among the N consecutive measurement gap opportunities notified. Alternatively, a bit value "0" can represent "not skipped (not skipped)," and a bit value "1" can represent "skipped (skipped)," or a bit value "1" can represent "not skipped (not skipped)," and a bit value "0" can represent "skipped (skipped)." For measurement gap opportunities notified as "skipped," terminal 200 can also receive / transmit DL / UL channels / signals without performing RRM measurements or applying the scheduling constraints defined in existing standards during those measurement gap opportunities. On the other hand, for measurement gap opportunities notified as "not skipped," terminal 200 needs to perform RRM measurements during those measurement gap opportunities and apply the scheduling constraints defined in existing standards during those non-skipped measurement gap opportunities.

[0183] The initial measurement gap opportunity among N consecutive measurement gap opportunities can also be determined as the initial measurement gap opportunity after X symbols / slots following the final symbol / slot of the DCI used for notification (or, for the HARQ-ACK of the PDSCH corresponding to the MAC CE used for notification). In this way, terminal 200 can also determine the initial measurement gap opportunity to be skipped based on the DCI / MAC CE. The value of X can also be defined by a standard, set by RRC, or notified via the DCI / MAC CE used for notification.

[0184] In addition, the value of N can be defined by a standard, set by RRC, or notified via DCI / MAC CE.

[0185] Figure 10 This illustrates an example of skipping notifications based on Alt 2-3 measurement gap opportunities, where DCI notifies N (in) via a bitmap. Figure 10 The example shown illustrates a skipping mode for consecutive measurement gap opportunities (N=4). In this example, the bitmap (skip mode) is "0100" (where 0: not skipped, 1: skipped), and the second measurement gap opportunity shown is skipped. Therefore, terminal 200 can also decide to skip the second measurement gap opportunity shown, in which RRM measurement is not performed, but DL / UL channels / signals are received / transmitted.

[0186] ·Alt 2-4

[0187] The DCI or MAC CE can also notify the terminal 200 to deactivate the set measurement gap until another DCI or MAC CE is received to activate the measurement gap. In other words, if the terminal 200 receives a DCI or MAC CE to deactivate the measurement gap, it can continue to deactivate the measurement gap (state) until another DCI or MAC CE to activate the measurement gap is received. The DCI or MAC CE to deactivate the measurement gap can also be referred to as information indicating (in another) part of the periodic extension period used for measurement) the execution of measurement, etc.

[0188] As an example of Alt 2-4, if terminal 200 detects or receives a notification from base station 100 to deactivate the measurement gap DCI or MAC CE, terminal 200 may also decide to deactivate the measurement gap opportunity after the X symbol / time slot of the final symbol / time slot of the notification DCI (or, for the HARQ-ACK of the PDSCH corresponding to the notification MAC CE). The value of X can be defined by a standard, set by RRC, or notified by the notification DCI / MAC CE.

[0189] When multiple measurement gaps or measurement gap settings are configured, the DCI or MAC CE can either notify the activation of all configured measurement gaps or measurement gap settings, or notify the activation of a specific measurement gap or measurement gap setting. For example, when the DCI or MAC CE notifies the activation of a specific measurement gap or measurement gap setting, the DCI or MAC CE can also notify the corresponding measurement gap (setting) ID (or index) or FR.

[0190] If the measurement gap is deactivated, and terminal 200 detects or receives a notification from base station 100 of (other) DCI or MAC CE activating the measurement gap, terminal 200 may also decide to activate the measurement gap opportunity after the Y symbol / time slot of the final symbol / time slot of the (other) DCI used for notification (or, for the HARQ-ACK of the PDSCH corresponding to the (other) MAC CE used for notification). The value of Y can also be defined by a standard, set by RRC, or notified by the (other) DCI / MAC CE used for notification.

[0191] Figure 11An example of skipping measurement gap opportunities based on Alt 2-4 is shown, i.e., an example where, after a DCI notifies of deactivating a measurement gap, another DCI notifies of activating a measurement gap. In this example, before the initial measurement gap opportunity shown in the illustration, the DCI notifies of deactivating the measurement gap. Therefore, subsequent measurement gap opportunities that meet the above conditions are deactivated / skipped. In this example, from the initial measurement gap opportunity up to the third measurement gap opportunity before receiving another DCI, they are skipped. After the third measurement gap opportunity, another DCI notifies of activating the measurement gap. Therefore, subsequent measurement gap opportunities are activated / not skipped (until yet another DCI notifies of deactivating the measurement gap). Thus, terminal 200 can also decide to skip the initial to third measurement gap opportunities shown in the illustration, not performing RRM measurements during these measurement gap opportunities, but receiving / transmitting DL / UL channels / signals. On the other hand, terminal 200 decides not to skip the last measurement gap opportunity shown in the illustration, requiring RRM measurements to be performed during this measurement gap opportunity, applying the scheduling constraints defined in existing standards during the measurement gap opportunities that are not skipped.

[0192] Variations of Alt 2-1 / 2-2 / 2-3 / 2-4

[0193] Dynamic notifications based on DCI or MAC CE can be applied to more than one specific measurement gap type (e.g., FR1 measurement gap or FR2 measurement gap, etc.) or only to the measurement gap per UE.

[0194] In addition, when multiple measurement gap settings are set, the following options a / b can also be used.

[0195] Option a

[0196] Dynamic notifications based on DCI or MAC CE can also be sent to all measurement gap settings. That is, dynamic notifications based on DCI or MAC CE can also be a common notification for multiple measurement gap settings.

[0197] Option b

[0198] Dynamic notifications based on DCI or MAC CE can also be sent out on a per-measurement-gap basis. That is, the target measurement gap setting also needs to be notified in the dynamic notification based on DCI or MAC CE.

[0199] Additionally, in this application, the measurement gap (opportunity) may also be referred to as an extended period or interval for measurement, etc.

[0200] <Operation example>

[0201] Next, refer to Figure 21 The operation example of terminal 200 is explained.

[0202] In step S21, terminal 200 receives from base station 100 first information related to the extended period of the measurement using the measurement signal. For example, the first information may be an existing measurement gap setting information element (e.g., MeasGapConfig IE) as an RRC parameter or a (new) information element that is the same as that information element.

[0203] In step S22, the terminal 200 periodically sets the duration of the measurement extension using the measurement signal based on the received first information.

[0204] In step S23, terminal 200 receives second information from base station 100 indicating that no measurement will be performed during a portion of the periodically extended period. For example, the second information could also be a semi-static notification as described in Alt 1 / a dynamic notification as described in Alt 2.

[0205] In step S24, based on the received second information, the terminal 200 does not perform measurements during a portion of the periodically extended period, but performs signal reception or transmission with the base station.

[0206] According to Proposal 2, measurement gaps (opportunities) can be skipped or deactivated based on semi-static / dynamic notifications from the base station, thus reducing the impact of scheduling constraints related to measurement.

[0207] <Proposal 3>

[0208] As Proposal 3, it describes support for reporting requests / notifications made by the terminal to skip or deactivate measurement gaps.

[0209] Terminal 200 can also report a request / notification to base station 100 to skip or deactivate a measurement gap via UCI / MAC CE on PUCCH / PUSCH. In the case of PUCCH / PUSCH, the PUCCH / PUSCH resources used by terminal 200 to report the request / notification to skip or deactivate a measurement gap can be set via RRC or notified via scheduling DCI. The request / notification to skip or deactivate a measurement gap can also be referred to as information indicating that measurement will not be performed (during a periodic extension for measurement).

[0210] Reports of requests / notifications to skip or deactivate measurement gaps can be periodic, semi-persistent, non-periodic, or event-triggered. In the case of such event-triggered reports, the event could be, for example, an event indicating a condition where measurement is not required. For example, the event could be a specific number of times during a measurement period (SMTC window, etc.) in which the received quality of the measured signal (SSB, etc.) is within a specific range, or a specific number of consecutive measurements during which the received quality of the measured signal is within a specific range.

[0211] The report content and reporting process can also follow options 1 / 2 / 3 below.

[0212] [Option 1]

[0213] Terminal 200 may also report a request to base station 100 to trigger skipping or deactivating the measurement gap. Terminal 200 may also monitor / receive a notification from base station 100 (sent from base station 100) after reporting the request to base station 100, indicating whether the measurement gap should be skipped or deactivated. In Option 1, the method for skipping the measurement gap may also rely on a notification from base station 100. That is, base station 100 may also notify terminal 200 how to skip the measurement gap (terminal 200 may also be notified from base station 100 how to skip the measurement gap).

[0214] The notification from base station 100 regarding how to skip the measurement gap can also follow Proposal 2 described above (including options, Alt 1 / 2 (Alt 2-1~Alt 2-4)). That is, the operation of terminal 200 when skipping the measurement gap opportunity can also follow the notification from base station 100 as described in Proposal 2 described above.

[0215] For example, such as Figure 12 As shown, after sending the request to the base station 100, the terminal 200 receives a notification from the base station 100 regarding how to skip the measurement gap. Then, based on the notification from the base station 100, the terminal 200 skips the measurement gap opportunity.

[0216] [Option 2]

[0217] Terminal 200 can also report to base station 100 requests to skip or deactivate measurement gaps, and information related to suggested skipping occasions (skipped measurement gap opportunities). In this case, terminal 200 also requests / suggests skipped measurement gap opportunities.

[0218] Option 2 requires either a notification from base station 100 regarding how to skip the measurement gap, or a confirmation from base station 100 confirming (allowing, authorizing) the request to skip or deactivate the measurement gap. In the former case, terminal 200 follows the notification from base station 100 and skips the measurement gap opportunity; in the latter case, terminal 200 skips the measurement gap opportunity as requested / prompted by terminal 200. This will be discussed later. Figure 13 as well as Figure 14 Let me explain.

[0219] The content of a request made by terminal 200 may also include one or more of the following options 2-a to 2-d.

[0220] Option 2-a: Skip N consecutive measurement interval opportunities (N is an integer greater than or equal to 1).

[0221] The initial measurement gap opportunity that is skipped can also be the initial measurement gap opportunity after the X symbol / slot of the final symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). Terminal 200 can also determine the initial measurement gap opportunity that is skipped in this way. The value of X can also be defined by a standard, set by RRC, or notified by the request.

[0222] In addition, the value of N can be defined by a standard (e.g., N=1), set by an RRC, or notified by the request.

[0223] Option 2-b: Skip the measurement gap opportunity within the window.

[0224] The start of the skip window can also be after the X symbol / slot of the final symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). Terminal 200 can also determine the start of the skip window in this way. The value of X can also be defined by the standard, set by RRC, or notified by the request.

[0225] In addition, the length of the skip window can be defined by a standard, set by an RRC, or notified by the request.

[0226] Option 2-c: Skip mode related to whether to skip or not skip for each of N consecutive measurement gap opportunities (N is an integer greater than or equal to 1).

[0227] The request may also include a bitmap in which each bit indicates whether to skip or not skip the corresponding measurement gap opportunity among the N consecutive measurement gap opportunities notified. Alternatively, a bit value of "0" can represent "not skipped (not skipped)" and a bit value of "1" can represent "skipped (skipped)", or a bit value of "1" can represent "not skipped (not skipped)" and a bit value of "0" can represent "skipped (skipped)".

[0228] The first measurement gap opportunity among N consecutive measurement gap opportunities can also be the first measurement gap opportunity after X symbols / slots of the final symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). Terminal 200 can also determine the first measurement gap opportunity to be skipped in this way. The value of X can also be defined by a standard, set by RRC, or notified by the request.

[0229] In addition, the value of N can be defined by a standard, set by an RRC, or notified through this request.

[0230] Option 2-d: Terminal 200 may also notify the deactivation of the set measurement gap (keeping the deactivation state unchanged) until a request to activate the measurement gap is sent. The request to activate the measurement gap may also be referred to as information indicating (in other) parts of the periodic extension used for measurement) to perform the measurement, etc.

[0231] Terminal 200 can also decide to activate the measurement gap opportunity after the X symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). The value of X can also be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0232] If the measurement gap is deactivated, and terminal 200 sends an (other) request to activate the measurement gap, terminal 200 may also decide to activate the measurement gap opportunity after the Y symbol / time slot of the final symbol / time slot of the (other) request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the (other) request). The value of Y can also be defined by a standard, set by RRC, or notified by the (other) request.

[0233] Variations of options 2-a / 2-b / 2-c / 2-d

[0234] The content of the request made by terminal 200 can also be for one or more of the following Alt 1 to Alt 3.

[0235] Alt 1

[0236] The content of the request made by terminal 200 can also be content for all measurement gap settings / types.

[0237] Alt 2

[0238] The content of the request made by terminal 200 may also be the content of setting one or more specific measurement gaps, and the setting of one or more measurement gaps that are objects may also be included in the request.

[0239] Alt 3

[0240] The content requested by terminal 200 can also be content specific to a particular measurement gap type (e.g., measurement gap for each UE / FR, FR1 / FR2 measurement gap, etc.).

[0241] The operation of terminal 200 after reporting a request to base station 100 to skip or deactivate the measurement gap (e.g., following the request of option 2-a / 2-b / 2-c / 2-d) can also follow the following option 2-1 / 2-2.

[0242] Option 2-1

[0243] Terminal 200 may also monitor / receive notifications from base station 100 that indicate skipping or deactivating measurement gaps (the notification is sent from base station 100). In option 2-1, how to skip measurement gaps may also depend on notifications from base station 100. That is, base station 100 may also notify terminal 200 how to skip measurement gaps (terminal 200 may also be notified from base station 100 how to skip measurement gaps).

[0244] The notification from base station 100 regarding how to skip the measurement gap can also follow Proposal 2 described above (including options, Alt 1 / 2 (Alt 2-1~Alt 2-4)). That is, the operation of terminal 200 when skipping the measurement gap opportunity can also follow the notification from base station 100 as described in Proposal 2 described above.

[0245] For example, such as Figure 13 As shown, after sending the request and instructions on how to skip the measurement gap to the base station 100, terminal 200 receives a notification from base station 100 on how to skip the measurement gap. Then, based on the notification from base station 100, terminal 200 skips the measurement gap opportunity.

[0246] Option 2-2

[0247] Terminal 200 may also monitor / receive confirmations from base station 100 of requests to skip or deactivate measurement gaps (the confirmation is sent from base station 100). If terminal 200 receives the confirmation (in the monitoring window), it can skip the measurement gap opportunity as requested. On the other hand, if terminal 200 does not receive the confirmation (in the monitoring window), it cannot skip the measurement gap opportunity as requested.

[0248] The monitoring window described above can also be configured as follows.

[0249] • The start of the monitoring window can be the first symbol / slot after the K symbol / slot of the request, or it can be the first PDCCH monitored symbol / slot after the request (for a specific search space type or a specific DCI format).

[0250] • The length of the monitoring window can be defined by a standard, set by RRC, or reported in the request.

[0251] For example, such as Figure 14 As shown, after sending the request and instructions on how to skip the measurement gap to the base station 100, the terminal 200 receives an acknowledgment from the base station 100. Then, the terminal 200 skips the measurement gap opportunity as requested (instructed) (e.g., based on the requested (instructed) skip mode).

[0252] As a variation of option 2-2, if the request made by terminal 200 is a request for multiple measurement gap settings / types, the confirmation by base station 100 may also follow the following Alt 1 / 2.

[0253] Alt 1: A single confirmation can also be applied only to requests for multiple measurement gap settings / types.

[0254] Alt 2: Terminal 200 can also be set / type assumed (received) for each measurement gap.

[0255] [Option 3]

[0256] Terminal 200 may also report to base station 100 a notification of skipping or deactivating a measurement gap opportunity. In option 3, without the need for notification from base station 100 on how to skip the measurement gap, or confirmation from base station 100 of a request to confirm (allow, authorize) skipping or deactivating the measurement gap, terminal 200 may skip the measurement gap opportunity as notified by terminal 200.

[0257] The content of the notification issued by terminal 200 may also include one or more of options 2-a to 2-d (including variations) of proposal 3 above. Here, in options 2-a to 2-d of proposal 3 above, "request" may also be replaced with "notification".

[0258] The operation of terminal 200 after reporting to base station 100 a notification to skip or deactivate the measurement gap (e.g., a notification following options 2-a / 2-b / 2-c / 2-d of proposal 3 above) can also be described as follows.

[0259] • For measurement gap opportunities that are notified as “skipped / deactivated”, terminal 200 does not perform RRM measurements during the measurement gap opportunity and does not apply the scheduling restrictions defined in the existing standards (terminal 200 may also receive / transmit DL / UL channels / signals).

[0260] • For measurement gap opportunities that are notified to be “not skipped / activated”, terminal 200 needs to perform RRM measurements in the measurement gap opportunity and apply the scheduling constraints defined in the existing standard in the measurement gap opportunities that are not skipped.

[0261] For example, such as Figure 15 As shown, after sending the notification to the base station 100, the terminal 200 skips the measurement gap opportunity as notified (e.g., based on the notified skip mode) without needing to receive notification and confirmation from the base station 100.

[0262] [Variations of options 1 / 2 / 3]

[0263] In the presence of multiple measurement gap settings / types, terminal 200 may also report to base station 100 a request / instruction that does not include details related to the measurement gap setting / type to which the request / notification to skip or deactivate the measurement gap is the object (or report to base station 100 a request / notification to skip or deactivate the measurement gap for all of the multiple measurement gap settings / types), and may also report to base station 100 information related to the object measurement gap setting or specific measurement gap type (e.g., each UE / FR, FR1 / FR2, etc.) to which it intends to skip or deactivate.

[0264] Additionally, in this application, the measurement gap (opportunity) may also be referred to as an extended period or interval for measurement, etc.

[0265] <Operation example>

[0266] Next, refer to Figure 22 An example of operating the terminal 200 is explained.

[0267] In step S31, terminal 200 receives from base station 100 first information related to the extended period of the measurement using the measurement signal. For example, the first information may be an existing measurement gap setting information element (e.g., MeasGapConfig IE) as an RRC parameter or a (new) information element that is the same as that information element.

[0268] In step S32, the terminal 200 periodically sets the duration of the measurement extension using the measurement signal based on the received first information.

[0269] In step S33, terminal 200 sends a second message to base station 100 indicating that no measurement will be performed. For example, the second message may also be a request as described in option 1 / 2 or a notification as described in option 3.

[0270] In step S34, the terminal 200, based on the transmission of the second information in step S33, does not perform measurements during a portion of the periodically extended period, but performs signal reception or transmission with the base station.

[0271] Additionally, between steps S33 and S34, sometimes as described in option 1 / 2-1, base station 100 sends a notification to terminal 200 on how to skip the periodic extension period (indicating that no measurement will be performed during a portion of the periodic extension period), sometimes as described in option 2-2, it sends an acknowledgment to terminal 200 that no measurement will be performed during a portion of the periodic extension period, and sometimes as described in option 3, no exchange occurs between terminal 200 and base station 100.

[0272] According to Proposal 3, it is possible to skip or deactivate measurement gaps (opportunities) based on requests / notifications from the terminal, thereby reducing the impact of scheduling constraints caused by measurement.

[0273] <Proposal 4>

[0274] As Proposal 4, support for periodic / semi-continuous / non-periodic measurement gaps is explained.

[0275] In proposals 1-3 above, the measurement gap was assumed to be periodic. However, the measurement gap is not limited to periodicity. Specifically, the measurement gap can also include periodic measurement gaps, semi-continuous measurement gaps, and non-periodic measurement gaps.

[0276] Regarding periodic measurement gaps, once a periodic measurement gap is set, it can remain active (or in a valid state). In this case, terminal 200 can also receive RRC parameters from base station 100 that set the periodic measurement gap, and perform intra-frequency RRM measurement / inter-frequency RRM measurement during each set measurement gap opportunity. The aforementioned RRC parameters can be, for example, information elements that add parameters representing measurement gap types such as periodic measurement gaps, semi-continuous measurement gaps, and non-periodic measurement gaps to existing RRM measurement setting information elements (e.g., MeasGapConfig IE), or they can be (new) information elements for periodic measurement gaps that are the same as those information elements.

[0277] Regarding semi-persistent measurement gaps, these gaps can also be activated / deactivated using a DCI or MAC CE for activation / deactivation. If terminal 200 receives RRC parameters for setting a semi-persistent measurement gap, and detects or receives a DCI or MAC CE from base station 100 to activate the measurement gap for that specified gap (if the semi-persistent measurement gap is activated), terminal 200 can also perform intra-frequency RRM measurements / inter-frequency RRM measurements during each measurement gap opportunity (until a DCI or MAC CE to deactivate the measurement gap is detected or received). Furthermore, if a semi-persistent measurement gap is activated, scheduling constraints defined in previous standards can also be applied. On the other hand, if terminal 200 detects or receives a DCI or MAC CE deactivating the measurement gap (if a semi-persistent measurement gap is deactivated), terminal 200 may also not perform intra-frequency RRM measurement / inter-frequency RRM measurement during each measurement gap opportunity, but instead receive / transmit DL / UL channels / signals (until a DCI or MAC CE activating the measurement gap is detected or received). The aforementioned RRC parameters may, for example, be information elements that add parameters representing measurement gap types such as periodic measurement gaps, semi-persistent measurement gaps, and non-periodic measurement gaps to existing RRM measurement setting information elements (e.g., MeasGapConfig IE), or they may be (new) information elements used for semi-persistent measurement gaps, similar to these information elements.

[0278] Regarding aperiodic measurement gaps, aperiodic measurement gaps can also be activated via DCI or MAC CE. If terminal 200 receives RRC parameters for setting aperiodic measurement gaps, and detects or receives activation DCI or MAC CE from base station 100 for the set measurement gap (if the aperiodic measurement gap is activated), terminal 200 can also perform intra-frequency RRM measurement / inter-frequency RRM measurement during the notified measurement gap opportunity. The aforementioned RRC parameters can be, for example, information elements that add parameters representing measurement gap types such as periodic measurement gaps, semi-continuous measurement gaps, and aperiodic measurement gaps to existing RRM measurement setting information elements (e.g., MeasGapConfig IE), or (new) information elements for aperiodic measurement gaps that are the same as those information elements.

[0279] <Operation example>

[0280] Next, refer to Figure 23 An operational example of the terminal 200 related to the semi-continuous measurement gap is described.

[0281] In step S41, terminal 200 receives from base station 100 first information related to the extended period of the measurement using the measurement signal. For example, the first information may be a measurement gap setting information element (e.g., MeasGapConfig IE) as an RRC parameter or a (new) information element that is the same as that information element.

[0282] In step S42, the terminal 200 periodically sets the duration of the measurement extension using the measurement signal based on the received first information.

[0283] In step S43, terminal 200 receives second information from base station 100 for activating the extended period. For example, the second information could also be DCI or MAC CE for activating a measurement gap described for a semi-persistent measurement gap.

[0284] In step S44, the terminal 200 performs measurements during the subsequent extended period, without receiving or transmitting signals with the base station.

[0285] Furthermore, if terminal 200 subsequently receives third information from base station 100 for deactivating the extended period, terminal 200 may also perform signal reception or transmission without performing measurement during the extended period. For example, the third information may also be a DCI or MAC CE for deactivating a measurement gap specified for a semi-persistent measurement gap.

[0286] In addition, for periodic measurement gaps, steps S41 and S42 can be performed, and then steps S43 and S44 can be omitted to activate the periodic extension period.

[0287] Furthermore, for non-periodic measurement gaps, after executing steps S41 to S43, the terminal 200 performs measurements only during an extended period in step S44.

[0288] Furthermore, this proposal can also be applied to multiple measurement gaps (settings). In this case, a list of multiple measurement gaps (settings) can also be set via RRC.

[0289] According to Proposal 4, the impact of measurement-related scheduling constraints can be reduced by activating and deactivating semi-persistent measurement gaps and deactivating / activating non-periodic measurement gaps.

[0290] <Proposal 5>

[0291] As Proposal 5, it describes support for notifications made by the base station to skip or deactivate RRM measurements.

[0292] Operations of terminal 200 related to skipping or deactivating RRM measurements can also be based on notifications from base station 100.

[0293] For example, if terminal 200 is notified from base station 100 to skip or deactivate an RRM measurement opportunity (e.g., an SMTC window), terminal 200 will not perform RRM measurement during the RRM measurement opportunity, and previous scheduling restrictions will not be applied to the symbols being measured or the symbols within the SMTC window. If the RRM measurement is not accompanied by a measurement gap, terminal 200 may also (within the SMTC window) receive DL channels / signals in the measured SSB / CSI-RS symbols, or receive / transmit DL / UL channels / signals in all symbols within the SMTC window.

[0294] Skipping or deactivating RRM measurements can also follow option 1 / 2 below.

[0295] [Option 1]

[0296] Skipping or deactivating RRM measurements can also be notified / set on a per-RRM measurement basis. More specifically, skipping or deactivating RRM measurements can also follow options 1-1 / 1-2 below.

[0297] Option 1-1

[0298] The skipping or deactivation of RRM measurement opportunities can also be notified via a semi-static notification based on RRC or SIB. The semi-static RRM measurement skipping or deactivation mode can also be set per RRM measurement via RRC. The semi-static notification based on RRC or SIB can also be referred to as information indicating (within a period associated with the measurement) that a measurement will not be performed, etc. Terminal 200 can also be notified of the skipping or deactivation of RRM measurement opportunities by receiving this semi-static notification from base station 100, and can also determine which RRM measurement opportunities to skip and / or not to skip based on this semi-static notification.

[0299] Options 1-2

[0300] The skipping or deactivation of RRM measurement opportunities can also be notified via dynamic notification. Dynamic notification (e.g., DCI or MAC CE) can also notify of the skipping or deactivation of an RRM measurement for a specific RRM measurement setting. In this case, the object RRM measurement setting index (or ID) can also be notified via DCI or MAC CE. Dynamic notification can also be referred to as information indicating (within a periodic period associated with the measurement) that a measurement will not be performed, etc. Terminal 200 can also be notified of the skipping / deactivation of RRM measurement opportunities by receiving this dynamic notification from base station 100, and can also determine which RRM measurement opportunities to skip and which not to skip based on this dynamic notification. Dynamic notification can also follow the following options 1-2-1 / 1-2-2 / 1-2-3 / 1-2-4.

[0301] Option 1-2-1

[0302] As illustrated in Alt 2-1 of Proposal 2, DCI or MAC CE can also notify the skipping of N (N is an integer greater than 1) consecutive RRM measurement opportunities.

[0303] As an example of option 1-2-1, the initial RRM measurement opportunity that is skipped can also be the initial RRM measurement opportunity after the X symbols / slots of the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK for the PDSCH corresponding to the MAC CE used for the notification). In this way, terminal 200 can also determine the initial RRM measurement opportunity that is skipped based on the DCI / MAC CE. The value of X can also be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0304] In addition, the value of N can be defined by a standard (e.g., N=1), set by RRC, or notified via DCI / MAC CE.

[0305] RRM measurement opportunities not included in N consecutive RRM measurement opportunities are not skipped. Terminal 200 needs to perform RRM measurements during the non-skipped RRM measurement opportunities, applying the scheduling constraints defined in the existing standard. Alternatively, terminal 200 may not perform RRM measurements during N consecutive RRM measurement opportunities, but instead receive / transmit DL / UL channels / signals.

[0306] Option 1-2-2

[0307] As described in Alt 2-2 of Proposal 2, the DCI or MAC CE can also notify the skipping of RRM measurement opportunities within a skip window. The skip window may also be referred to as the measurement non-execution period, the period during which measurements are not performed, etc.

[0308] As an example of option 1-2-2, the start of the skip window can also be after the X symbol / slot of the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK for the PDSCH corresponding to the MAC CE used for the notification). In this way, terminal 200 can also determine the start of the skip window based on the DCI / MAC CE. The value of X can also be defined by the standard, set by RRC, or notified via the DCI / MAC CE used for the notification.

[0309] In addition, the length of the skip window can be defined by a standard, set by RRC, or notified via DCI / MAC CE.

[0310] RRM measurement opportunities not included in the skip window are not skipped. Terminal 200 needs to perform RRM measurements on non-skipped RRM measurement opportunities, applying scheduling constraints defined in existing standards. For RRM measurement opportunities included in the skip window, terminal 200 may also receive / transmit DL / UL channels / signals without performing RRM measurements.

[0311] Options 1-2-3

[0312] As illustrated in Alt 2-3 of Proposal 2, DCI or MAC CE can also inform whether to skip or not skip each of N (N being an integer greater than 1) consecutive RRM measurement opportunities.

[0313] As an example of option 1-2-3, the DCI or MAC CE may also notify (or include) a bitmap in which each bit indicates whether to skip or not skip the corresponding RRM measurement opportunity among the N consecutive RRM measurement opportunities notified. Alternatively, a bit value of "0" can represent "not skipped (not skipped)," and a bit value of "1" can represent "skipped (skipped)," or a bit value of "1" can represent "not skipped (not skipped)," and a bit value of "0" can represent "skipped (skipped)." For RRM measurement opportunities notified as "skipped," terminal 200 may also not perform RRM measurements in that RRM measurement opportunity, and may not apply the scheduling constraints defined in the existing standard, while receiving / transmitting DL / UL channels / signals. On the other hand, for RRM measurement opportunities notified as "not skipped," terminal 200 needs to perform RRM measurements in that RRM measurement opportunity, and apply the scheduling constraints defined in the existing standard in the RRM measurement opportunities not skipped.

[0314] The initial RRM measurement opportunity among N consecutive RRM measurement opportunities can also be determined as the initial RRM measurement opportunity after X symbols / slots following the final symbol / slot of the DCI used for notification (or, for the HARQ-ACK of the PDSCH corresponding to the MAC CE used for notification). In this way, terminal 200 can also determine the initial RRM measurement opportunity to be skipped based on the DCI / MAC CE. The value of X can also be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0315] In addition, the value of N can be defined by a standard, set by RRC, or notified via DCI / MAC CE.

[0316] Options 1-2-4

[0317] As explained in Alt 2-4 of Proposal 2, the DCI or MAC CE can also notify the deactivation of the configured RRM measurement until the terminal 200 receives another DCI or MAC CE to activate the RRM measurement. In other words, if the terminal 200 receives a DCI or MAC CE to deactivate the RRM measurement, it can continue to deactivate the RRM measurement (state) until it receives another DCI or MAC CE to activate the RRM measurement. Other DCIs or MAC CEs to activate the RRM measurement can also be referred to as information indicating (in other) parts of a periodic period associated with the measurement) that the measurement is being performed.

[0318] As an example of option 1-2-4, if terminal 200 detects or receives a DCI or MAC CE from base station 100 notifying the deactivation of RRM measurement, terminal 200 may also decide to activate RRM measurement after X symbols / time slots of the final symbol / time slot of the DCI used for notification (or, for the HARQ-ACK of the PDSCH corresponding to the MAC CE used for notification). The value of X can also be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0319] If the RRM measurement is deactivated, and terminal 200 detects or receives from base station 100 announcing the activation of the RRM measurement via (other) DCI or MAC CE, terminal 200 may also decide to activate the RRM measurement after the Y symbol / slot of the final symbol / slot of the (other) DCI used for the announcement (or, for the HARQ-ACK of the PDSCH corresponding to the (other) MAC CE used for the announcement). The value of Y can also be defined by a standard, set by RRC, or announced via the (other) DCI / MAC CE used for the announcement.

[0320] [Option 2]

[0321] Skipping or deactivating RRM measurements can also be done through notifications / settings for multiple RRM measurements (publicly). More specifically, skipping / deactivating RRM measurements can also follow options 2-1 / 2-2 below.

[0322] Option 2-1

[0323] The skipping or deactivation of RRM measurement opportunities can also be notified via a semi-static notification based on RRC or SIB. The semi-static RRM measurement skipping or deactivation mode can also be set via RRC. The semi-static notification based on RRC or SIB can also be referred to as information indicating (during a period associated with the measurement) that a measurement will not be performed, etc. Terminal 200 is notified of the skipping or deactivation of RRM measurement opportunities by receiving this semi-static notification from base station 100, and can also decide which RRM measurement opportunities to skip and / or not to skip based on this semi-static notification.

[0324] The RRM measurement skip or deactivation mode can also be applied to one or more of the following Alt a to Alt g.

[0325] Alt a: All RRM measurement settings are configured.

[0326] Alt b: Intra-frequency RRM measurement or inter-frequency RRM measurement

[0327] Alt c: RRM measurement based on SSB or RRM measurement based on CSI-RS

[0328] Alt d: RRM measurement with or without measurement gap

[0329] Alt e: RRM measurement settings for one or more cells (one or more cells can also be set via RRC, or predefined by a standard (e.g., cells in Pcell / Pscell / Scell, FR1 / FR2, etc.)).

[0330] Alt f: List of RRM measurement settings to be set

[0331] Alt g: RRM measurement settings for specific purposes or RRM measurement settings with specific priority values.

[0332] Option 2-2

[0333] The skipping or deactivation of RRM measurement opportunities can also be notified via dynamic notification. Dynamic notifications (e.g., DCI or MAC CE) can also notify of the skipping or deactivation of RRM measurements for multiple RRM measurement settings. Dynamic notifications can also be referred to as information indicating (within a periodic period associated with the measurement) that a measurement will not be performed, etc. Terminal 200 can also be notified of the skipping / deactivation of RRM measurement opportunities by receiving such dynamic notifications from base station 100, and can also determine which RRM measurement opportunities to skip and which not to skip based on such dynamic notifications. Dynamic notifications can also follow the following options 2-2-1 / 2-2-2 / 2-2-3 / 2-2-4.

[0334] Option 2-2-1

[0335] As illustrated in Alt 2-1 of Proposal 2, DCI or MAC CE can also notify the skipping of N (N is an integer greater than 1) consecutive RRM measurement opportunities.

[0336] As an example of option 2-2-1, the initial RRM measurement opportunity that is skipped can also be the initial RRM measurement opportunity after the X symbols / slots of the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK for the PDSCH corresponding to the MAC CE used for the notification). In this way, terminal 200 can also determine the initial RRM measurement opportunity that is skipped based on the DCI / MAC CE. The value of X can also be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0337] In addition, the value of N can be defined by a standard (e.g., N=1), set by RRC, or notified via DCI / MAC CE.

[0338] RRM measurement opportunities not included in N consecutive RRM measurement opportunities are not skipped. Terminal 200 needs to perform RRM measurements during the non-skipped RRM measurement opportunities, applying the scheduling constraints defined in the existing standard. Alternatively, terminal 200 may not perform RRM measurements during N consecutive RRM measurement opportunities, but instead receive / transmit DL / UL channels / signals.

[0339] Option 2-2-2

[0340] As described in Alt 2-2 of Proposal 2, the DCI or MAC CE can also notify the skipping of RRM measurement opportunities within a skip window. The skip window may also be referred to as the measurement non-execution period, the period during which measurements are not performed, etc.

[0341] As an example of option 2-2-2, the start of the skip window can also be after the X symbol / slot of the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK for the PDSCH corresponding to the MAC CE used for the notification). In this way, terminal 200 can also determine the start of the skip window based on the DCI / MAC CE. The value of X can also be defined by the standard, set by RRC, or notified via the DCI / MAC CE used for the notification.

[0342] In addition, the length of the skip window can be defined by a standard, set by RRC, or notified via DCI / MAC CE.

[0343] RRM measurement opportunities not included in the skip window are not skipped. Terminal 200 needs to perform RRM measurements on non-skipped RRM measurement opportunities, applying scheduling constraints defined in existing standards. For RRM measurement opportunities included in the skip window, terminal 200 may also receive / transmit DL / UL channels / signals without performing RRM measurements.

[0344] Option 2-2-3

[0345] As illustrated in Alt 2-3 of Proposal 2, DCI or MAC CE can also inform whether to skip or not skip each of N (N being an integer greater than 1) consecutive RRM measurement opportunities.

[0346] As an example of option 2-2-3, the DCI or MAC CE may also notify (or include) a bitmap in which each bit indicates whether to skip or not skip the corresponding RRM measurement opportunity among the N consecutive notified RRM measurement opportunities. Alternatively, a bit value of "0" can represent "not skipped (not skipped)," and a bit value of "1" can represent "skipped (skipped)," or a bit value of "1" can represent "not skipped (not skipped)," and a bit value of "0" can represent "skipped (skipped)." For RRM measurement opportunities notified as "skipped," terminal 200 may also not perform RRM measurements in that RRM measurement opportunity, and may not apply the scheduling constraints defined in the existing standard, while receiving / transmitting DL / UL channels / signals. On the other hand, for RRM measurement opportunities notified as "not skipped," terminal 200 needs to perform RRM measurements in that RRM measurement opportunity, and apply the scheduling constraints defined in the existing standard in RRM measurement opportunities that are not skipped.

[0347] The initial RRM measurement opportunity among N consecutive RRM measurement opportunities can also be determined as the initial RRM measurement opportunity after X symbols / slots following the final symbol / slot of the DCI used for notification (or, for the HARQ-ACK of the PDSCH corresponding to the MAC CE used for notification). In this way, terminal 200 can also determine the initial RRM measurement opportunity to be skipped based on the DCI / MAC CE. The value of X can also be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0348] In addition, the value of N can be defined by a standard, set by RRC, or notified via DCI / MAC CE.

[0349] Option 2-2-4

[0350] As explained in Alt 2-4 of Proposal 2, the DCI or MAC CE can also notify the deactivation of the configured RRM measurement until the terminal 200 receives another DCI or MAC CE to activate the RRM measurement. In other words, if the terminal 200 receives a DCI or MAC CE to deactivate the RRM measurement, it can continue to deactivate the RRM measurement (state) until it receives another DCI or MAC CE to activate the RRM measurement.

[0351] As an example of option 2-2-4, if terminal 200 detects or receives a DCI or MAC CE from base station 100 notifying the deactivation of RRM measurement, terminal 200 may also decide to activate RRM measurement after X symbols / time slots of the final symbol / time slot of the DCI used for notification (or, for the HARQ-ACK of the PDSCH corresponding to the MAC CE used for notification). The value of X can be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0352] If the RRM measurement is deactivated, and terminal 200 detects or receives from base station 100 announcing the activation of the RRM measurement via (other) DCI or MAC CE, terminal 200 may also decide to activate the RRM measurement after the Y symbol / time slot of the final symbol / time slot of the (other) DCI used for the announcement (or, for the HARQ-ACK of the PDSCH corresponding to the (other) MAC CE used for the announcement). The value of Y can be defined by a standard, set by RRC, or announced via the (other) DCI / MAC CE used for the announcement.

[0353] Dynamic notifications can also be applied to one or more of the following Alt h to Alt n.

[0354] Alt h: All RRM measurement settings are configured.

[0355] Alt i: Intra-frequency RRM measurement or inter-frequency RRM measurement

[0356] Alt j: RRM measurement based on SSB or RRM measurement based on CSI-RS

[0357] Alt k: RRM measurement with or without measurement gap

[0358] Alt l: RRM measurement settings for one or more cells (one or more cells can also be set via RRC, or predefined by a standard (e.g., cells in Pcell / Pscell / Scell, FR1 / FR2, etc.)).

[0359] Alt m: List of RRM measurement settings to be set

[0360] Alt n: RRM measurement settings for specific purposes or RRM measurement settings with specific priority values.

[0361] In addition, in this application, RRM measurement opportunity, SMTC window, SSB symbol, CSI-RS symbol, etc., may also be referred to as period or interval associated with measurement, period or interval used for measurement, measurement period or interval, etc.

[0362] <Operation example>

[0363] Next, refer to Figure 24 An example of operating the terminal 200 is explained.

[0364] In step S51, terminal 200 receives first information related to the measurement using the measurement signal from base station 100. For example, the first information may be an RRM measurement setting information element (e.g., MeasConfig IE) as an existing RRC parameter or a (new) information element that is the same as that information element.

[0365] In step S52, the terminal 200 periodically sets a period associated with the measurement using the measurement signal based on the received first information.

[0366] In step S53, terminal 200 receives second information from base station 100 indicating that no measurement will be performed during a portion of the periodic period. For example, the second information may also be a semi-static notification as described in options 1-1 / 2-1 / a dynamic notification as described in options 1-2 / 2-2.

[0367] In step S54, based on the received second information, the terminal 200 does not perform measurements during a portion of the periodic period, but performs signal reception or transmission with the base station.

[0368] According to Proposal 5, RRM measurements (opportunities) can be skipped or deactivated based on semi-static / dynamic notifications from the base station, thus reducing the impact of scheduling constraints related to measurements.

[0369] <Proposal 6>

[0370] As Proposal 6, support for reporting requests / notifications made by the terminal to skip or deactivate RRM measurements is described.

[0371] Terminal 200 can also report a request / notification to base station 100 to skip or deactivate RRM measurements via UCI / MAC CE on PUCCH / PUSCH. In the case of PUCCH / PUSCH, the PUCCH / PUSCH resources used by terminal 200 to report the request / notification to skip or deactivate RRM measurements can also be set via RRC or notified via scheduling DCI. The request / notification to skip or deactivate RRM measurements can also be referred to as information indicating (within a period of time associated with the measurement) that the measurement will not be performed, etc.

[0372] Reports of requests / notifications to skip or deactivate RRM measurements can be periodic, semi-persistent, non-periodic, or event-triggered. In the case of event-triggered reports, the event can, for example, indicate a condition where measurement is not required. For example, the event could be a specific number of times during consecutive measurement periods (SMTC window, etc.), or a specific number of consecutive measurements during which the received quality of the measured signal (SSB, etc.) is within a specific range.

[0373] The report content and reporting process can also follow options 1 / 2 / 3 below.

[0374] [Option 1]

[0375] Terminal 200 may also report a request to base station 100 to trigger skipping or deactivating RRM measurements. Terminal 200 may also monitor / receive a notification from base station 100 (sent from base station 100) after reporting the request to base station 100, indicating whether to skip or deactivate RRM measurements. In Option 1, the method for skipping RRM measurements may also rely on notifications from base station 100. That is, base station 100 may also notify terminal 200 how to skip RRM measurements (terminal 200 may also be notified from base station 100 how to skip RRM measurements).

[0376] The notification from base station 100 regarding how to skip RRM measurements can also follow Proposal 5 above. That is, the operation of terminal 200 when skipping RRM measurements can also follow the notification from base station 100, as described in Proposal 5 above.

[0377] For example, such as Figure 16 As shown, after sending the request to the base station 100, the terminal 200 receives a notification on how to skip the RRM measurement. Then, based on the notification from the base station 100, the terminal 200 skips the RRM measurement opportunity.

[0378] [Option 2]

[0379] Terminal 200 can also report to base station 100 a request to skip or deactivate RRM measurements, and information related to the requested / prompted skip opportunity (skipped RRM measurement opportunity). In this case, terminal 200 also requests / prompts the skipped RRM measurement gap opportunity.

[0380] Option 2 requires either a notification from base station 100 regarding how to skip the RRM measurement, or a confirmation from base station 100 of a request to acknowledge (allow, authorize) skipping or deactivating the RRM measurement. In the former case, terminal 200 follows the notification from base station 100 and skips the RRM measurement opportunity; in the latter case, terminal 200 skips the RRM measurement opportunity as requested / prompted by terminal 200. More details on this will be provided later. Figure 17 as well as Figure 18 Let me explain.

[0381] The content of a request made by terminal 200 may also include one or more of the following options 2-a to 2-d.

[0382] Option 2-a: Skip N consecutive RRM measurement opportunities (N is an integer greater than or equal to 1).

[0383] The initial RRM measurement opportunity that is skipped can also be the initial RRM measurement opportunity after the X symbol / slot of the final symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). Terminal 200 can also determine the initial RRM measurement opportunity that is skipped in this way. The value of X can also be defined by a standard, set by RRC, or notified by the request.

[0384] In addition, the value of N can be defined by a standard (e.g., N=1), set by an RRC, or notified by the request.

[0385] Option 2-b: Skip RRM measurement opportunities within the window

[0386] The start of the skip window can also be after the X symbol / slot of the final symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). Terminal 200 can also determine the start of the skip window in this way. The value of X can be defined by the standard, set by RRC, or notified by the request.

[0387] In addition, the length of the skip window can be defined by a standard, set by an RRC, or notified by the request.

[0388] Option 2-c: Skip mode related to whether to skip or not skip for each of N consecutive RRM measurement opportunities (N is an integer greater than or equal to 1).

[0389] The request may also include a bitmap in which each bit indicates whether to skip or not skip the corresponding RRM measurement opportunity among the N consecutive RRM measurement opportunities notified. Alternatively, a bit value of "0" can represent "not skipped (not skipped)" and a bit value of "1" can represent "skipped (skipped)", or a bit value of "1" can represent "not skipped (not skipped)" and a bit value of "0" can represent "skipped (skipped)".

[0390] The initial RRM measurement opportunity among N consecutive measurement gap opportunities can also be the initial RRM measurement opportunity after X symbols / slots of the final symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). Terminal 200 can also determine the initial RRM measurement opportunity to be skipped in this way. The value of X can also be defined by a standard, set by RRC, or notified by the request.

[0391] In addition, the value of N can be defined by a standard, set by an RRC, or notified through this request.

[0392] Option 2-d: Terminal 200 may also notify the deactivation of the configured RRM measurement (leaving the deactivation state unchanged) until a request to activate the RRM measurement is sent. The request to activate the RRM measurement may also be referred to as information indicating (in other) part of a periodic period associated with the measurement) to perform the measurement, etc.

[0393] Terminal 200 can also decide to activate the RRM measurement opportunity after the X symbol / slot of the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). The value of X can also be defined by a standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0394] If RRM measurement is deactivated, and terminal 200 sends an (other) request to activate RRM measurement, terminal 200 may also decide to activate the RRM measurement opportunity after the Y symbol / time slot of the final symbol / time slot of the (other) request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the (other) request). The value of Y can also be defined by a standard, set by RRC, or notified by the (other) request.

[0395] Variations of options 2-a / 2-b / 2-c / 2-d

[0396] The content of the request made by terminal 200 can also be for one or more of the following Alt 1 to Alt 3.

[0397] Alt 1

[0398] The content of the request made by terminal 200 can also be content for all RRM measurement settings / types.

[0399] Alt 2

[0400] The content of the request made by terminal 200 can also be the content of more than one specific RRM measurement setting, and more than one RRM measurement setting that is the object can also be included in the request.

[0401] Alt 3

[0402] The content requested by terminal 200 can also be content specific to a particular RRM measurement type (e.g., intra-frequency RRM measurement or inter-frequency RRM measurement, SSB-based RRM measurement or CSI-RS-based RRM measurement, RRM measurement with or without measurement gap, RRM measurement in FR1 or RRM measurement in FR2, etc.).

[0403] The operation of terminal 200 after reporting a request to base station 100 to skip or deactivate RRM measurement (e.g., following the request of option 2-a / 2-b / 2-c / 2-d) can also follow the following option 2-1 / 2-2.

[0404] Option 2-1

[0405] Terminal 200 may also monitor / receive notifications from base station 100 notifying the skipping or deactivation of RRM measurements (the notification is sent from base station 100). In option 2-1, how to skip RRM measurements may also depend on notifications from base station 100. That is, base station 100 may also notify terminal 200 how to skip RRM measurements (terminal 200 may also be notified from base station 100 how to skip RRM measurements).

[0406] The notification from base station 100 regarding how to skip RRM measurement can also follow Proposal 5 above. That is, the operation of terminal 200 when skipping RRM measurement opportunities can also follow the notification from base station 100 as described in Proposal 5 above.

[0407] For example, such as Figure 17As shown, after sending the request to the base station 100, the terminal 200 receives a notification from the base station 100 regarding how to skip the RRM measurement. Then, based on the notification from the base station 100, the terminal 200 skips the RRM measurement opportunity.

[0408] Option 2-2

[0409] Terminal 200 may also monitor / receive confirmations from base station 100 of requests to skip or deactivate RRM measurements (the confirmations are sent from base station 100). If terminal 200 receives such confirmations (in the monitoring window), it can skip the RRM measurement opportunity as requested. On the other hand, if terminal 200 does not receive such confirmations (in the monitoring window), it cannot skip the RRM measurement opportunity as requested.

[0410] The monitoring window described above can also be configured as follows.

[0411] • The monitoring window can start either as the first symbol / slot after the requested K symbol / slot, or as the first PDCCH monitored symbol / slot after the request (for a specific search space type or a specific DCI format).

[0412] • The length of the monitoring window can be defined by a standard, set by RRC, or reported in the request.

[0413] For example, such as Figure 18 As shown, after sending the request to base station 100, terminal 200 receives an acknowledgment from base station 100. Then, terminal 200 skips the RRM measurement opportunity as requested (prompted) (e.g., based on the requested (prompted) skip mode).

[0414] As a variation of option 2-2, if the request made by terminal 200 is for multiple RRM measurement settings / types, the confirmation by base station 100 may also follow Alt 1 / 2 below.

[0415] Alt 1: A single confirmation can also be applied only to requests for multiple RRM measurement settings / types.

[0416] Alt 2: Terminal 200 can also confirm each RRM measurement setting / type assumption (receive).

[0417] [Option 3]

[0418] Terminal 200 may also report to base station 100 a notification to skip or deactivate RRM measurement opportunities. In option 3, without the need for notification from base station 100 on how to skip RRM measurements, or confirmation from base station 100 of a request to confirm (allow, authorize) skipping or deactivating RRM measurements, terminal 200 may skip RRM measurement opportunities as notified by terminal 200.

[0419] The content of the notification issued by terminal 200 may also include one or more of options 2-a to 2-d (including variations) of proposal 6 above. Here, in options 2-a to 2-d of proposal 6 above, "request" may also be replaced with "notification".

[0420] The operation of terminal 200 after reporting to base station 100 a notification to skip or deactivate RRM measurement (e.g., a notification following options 2-a / 2-b / 2-c / 2-d of proposal 3 above) can also be described as follows.

[0421] • For RRM measurement opportunities that are notified as “skipped / deactivated,” terminal 200 does not perform RRM measurements during those RRM measurement opportunities, and scheduling restrictions defined in existing standards are not applied to the symbols being measured or the symbols within the SMTC window. When RRM measurements are not accompanied by measurement gaps, terminal 200 may receive DL channels / signals either (within the SMTC window) in the measured SSB / CSI-RS symbols or in all symbols within the SMTC window.

[0422] • For RRM measurement opportunities that are notified as “not skipped / activated”, terminal 200 needs to perform RRM measurements in that RRM measurement opportunity and apply the scheduling constraints defined in the existing standards in the non-skipped RRM measurement opportunities.

[0423] For example, such as Figure 19 As shown, after sending the notification to the base station 100, the terminal 200 skips the RRM measurement opportunity as notified (e.g., based on the notified skip mode) without needing to receive notification and confirmation from the base station 100.

[0424] [Variations of options 1 / 2 / 3]

[0425] In the presence of multiple RRM measurement settings / types, terminal 200 may also report to base station 100 a request / instruction that does not include details related to the RRM measurement setting / type to which the request / notification to skip or deactivate RRM measurement is targeted (or report to base station 100 a request / notification to skip or deactivate RRM measurement for all of the multiple RRM measurement settings / types), and may also report to base station 100 information related to the target RRM measurement setting or specific RRM measurement type that is intended to be skipped or deactivated (e.g., intra-frequency RRM measurement or inter-frequency RRM measurement, SSB-based RRM measurement or CSI-RS-based RRM measurement, RRM measurement with measurement gap or RRM measurement without measurement gap, RRM measurement in FR1 or RRM measurement in FR2, etc.).

[0426] In addition, in this application, RRM measurement opportunity, SMTC window, SSB symbol, CSI-RS symbol, etc., may also be referred to as period or interval associated with measurement, period or interval used for measurement, measurement period or interval, etc.

[0427] <Operation example>

[0428] Next, refer to Figure 25 An example of operating the terminal 200 is explained.

[0429] In step S61, terminal 200 receives first information related to the measurement using the measurement signal from base station 100. For example, the first information may be an existing RRM measurement setting information element (e.g., MeasConfig IE) as an RRC parameter or a (new) information element that is the same as that information element.

[0430] In step S62, the terminal 200 periodically sets a period associated with the measurement using the measurement signal based on the received first information.

[0431] In step S63, terminal 200 sends a second message to base station 100 indicating that no measurement will be performed. For example, the second message may also be a request as described in option 1 / 2 or a notification as described in option 3.

[0432] In step S64, the terminal 200, based on the transmission of the second information in step S63, does not perform measurements during a portion or other part of the periodic period, but performs signal reception or transmission with the base station.

[0433] Additionally, between steps S63 and S64, sometimes as described in option 1 / 2-1, base station 100 sends a notification to terminal 200 on how to skip the periodic period (indicating that no measurement will be performed during a portion of the periodic period), sometimes as described in option 2-2, it sends an acknowledgment to terminal 200 that no measurement will be performed during a portion of the periodic period, and sometimes as described in option 3, no exchange occurs between terminal 200 and base station 100.

[0434] According to Proposal 6, it is possible to skip or deactivate RRM measurements (opportunities) based on requests / notifications from the terminal, thereby reducing the impact of scheduling constraints caused by measurement.

[0435] <UE capability>

[0436] The UE capability, which represents the capabilities of the terminal, may also include information indicating the capabilities of the following terminals. Terminal 200 may also report this information, indicating the capabilities of the following terminals, to base station 100. Furthermore, the information indicating the capabilities of the terminal may also be equivalent to the information defining the capabilities of the terminal.

[0437] • Define whether the terminal supports prioritizing channel / signal transmission / reception over RRM measurements based on more than one specific condition.

[0438] • Define whether the terminal supports base station-based notifications, skipping or deactivating measurement gap information.

[0439] • Define whether the terminal supports (in PUCCH / PUSCH / MAC CE) (periodic / semi-persistent / non-periodic / event-triggered) reporting requests / notifications for skipping or deactivating measurement gaps.

[0440] • Define whether the terminal supports information on periodic / semi-continuous / non-periodic measurement gaps.

[0441] • Define whether the terminal supports base station-based notifications, skipping or deactivating RRM measurement information.

[0442] • Define whether the terminal supports (in PUCCH / PUSCH / MAC CE) (periodic / semi-persistent / aperiodic / event-triggered) reporting requests / notifications for skipping or deactivating RRM measurements.

[0443] • Define the minimum processing time for notifications / acknowledgments used to handle skipping or deactivation of measurement gap opportunities / RRM measurement opportunities (e.g., “X” in X symbol / slot, “K” in K symbol / slot, etc. above).

[0444] Furthermore, the above description illustrates an example of exchanging notifications and requests (skip mode, etc.) for skipping or deactivating measurement gaps (opportunities) and RRM measurements (opportunities) between base station 100 and terminal 200. However, it is also possible to exchange notifications and requests (skip mode, etc.) for not skipping or activating measurement gaps (opportunities) and RRM measurements (opportunities).

[0445] Next, the structures of base station 100 and terminal 200 will be described. Furthermore, the structures of base station 100 and terminal 200 described below represent one example of the functions associated with this embodiment. Base station 100 and terminal 200 may also have functions not shown. Moreover, the functional distinctions and / or names of functional units are not limited as long as they perform the operations involved in this embodiment.

[0446] <Base station structure>

[0447] Figure 26 This is a block diagram illustrating an example of the structure 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 wirelessly with a terminal 200 (see reference 100). Figure 27 ) to communicate.

[0448] 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, acknowledgment, etc. mentioned above) under the control of the control unit 103.

[0449] The DL signal may also include, for example, downlink data signals and control information (e.g., Downlink Control Information (DCI)). Furthermore, the DL signal may also include scheduling information related to signal transmission of the terminal 200 (e.g., UL authorization). Additionally, the DL signal may also include higher-layer control information (e.g., Radio Resource Control (RRC) control information). Furthermore, the DL signal may also include reference signals.

[0450] The channels used in transmitting DL signals may include, for example, downlink data channels and downlink control channels. For instance, 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 uses the PDCCH to transmit downlink control information and the PDSCH to transmit downlink data signals to terminal 200.

[0451] 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 location information. For example, reference signals such as DMRS and PTRS are used for demodulation of downlink data signals and are transmitted using PDSCH.

[0452] The receiving unit 102 receives uplink (UL) signals transmitted from the terminal 200. For example, the receiving unit 102 receives UL signals (e.g., requests, notifications, etc. mentioned above) under the control of the control unit 103.

[0453] The transmitting unit 101 and the receiving unit 102 can also be collectively referred to as the communication unit.

[0454] The control unit 103 controls the communication operation of the base station 100, which includes the transmission processing of the transmission unit 101 and the reception processing of the reception unit 102.

[0455] For example, control unit 103 obtains data and control information from higher layers and outputs it to transmitting unit 101. Furthermore, control unit 103 outputs data and control information received from receiving unit 102 to higher layers.

[0456] For example, the control unit 103 allocates resources (or channels) used in the transmission and reception of DL signals and / or UL signals based on signals received from the terminal 200 (e.g., data and control information) and / or data and control information obtained from higher layers. Information related to the allocated resources may also be included in the control information transmitted to the terminal 200.

[0457] <Terminal Structure>

[0458] Figure 27 This is a block diagram illustrating an example of the structure of the 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 the base station 100 wirelessly, for example.

[0459] Regarding Proposal 1, for example, if the timing of receiving the signal overlaps with the period (measurement gap opportunity, SMTC window, etc.) associated with the measurement using the measurement signal (SSB, etc.), the receiving unit 201 may also receive the signal from the base station 100 at the aforementioned timing according to the judgment of the control unit 203.

[0460] Regarding Proposal 2, for example, receiving unit 201 may also receive from base station 100 first information (RRC, etc.) related to the extended period (measurement gap opportunity, etc.) for measurements using measurement signals (SSB, etc.) (SSB measurement, etc.). For example, receiving unit 201 may also receive from base station 100 second information (RRC, SIB, MAC CE, DCI, etc.) indicating that measurements are not performed during a portion of the periodically extended period. For example, receiving unit 201 may also receive, after receiving the second information from base station 100, information indicating that measurements are performed during other portions of the periodically extended period (MAC CE, DCI, etc.). Receiving unit 201 may also receive signals from base station 100 during a portion of the periodically extended period.

[0461] Regarding Proposal 3, for example, the receiving unit 201 may also receive from the base station 100 first information (RRC, etc.) related to the extended period (measurement gap opportunity, etc.) for measurements using measurement signals (SSB, etc.) (SSB measurement, etc.). For example, the receiving unit 201 may also receive from the base station 100, after the second information (request, etc.) is sent to the base station 100, third information (RRC, SIB, MAC CE, DCI, etc.) indicating that measurements will not be performed during a portion of the periodically extended period. For example, the second information (request, etc.) may also indicate that measurements will not be performed during a portion or another portion of the periodically extended period, and the receiving unit 201 may also receive from the base station 100, after the second information is sent to the base station 100, fourth information (RRC, SIB, MAC CE, DCI, etc.) indicating that measurements will not be performed during a portion of the periodically extended period. For example, the second information (skip mode, etc., and request) may also indicate that no measurement will be performed during a portion of the periodically extended period. The receiving unit 201 may also receive, after the second information is sent to the base station 100, fourth information (RRC, SIB, MAC CE, DCI, etc.) indicating that no measurement will be performed during a portion of the periodically extended period. For example, the second information (skip mode, etc., and request) may also indicate that no measurement will be performed during a portion of the periodically extended period. The receiving unit 201 may also receive, after the second information is sent to the base station 100, fifth information (confirmation, etc.) confirming that no measurement will be performed during a portion of the periodically extended period. For example, the receiving unit 201 may also receive signals from the base station 100 during a portion of the periodically extended period based on the third, fourth, second, and fifth information. For example, the second information (skip mode, etc., and notification) may also indicate that no measurement will be performed during a portion of the periodically extended period. The receiving unit 201 may also receive signals from the base station 100 during a portion of the periodically extended period based on the second information.

[0462] Regarding Proposal 4, for example, receiving unit 201 may also receive from base station 100 first information (RRC, etc.) related to the extended period (measurement gap opportunity, etc.) of a measurement (SSB measurement, etc.) using a measurement signal (SSB, etc.). For example, receiving unit 201 may also receive from base station 100 second information (MAC CE, DCI, etc.) indicating the period of activation of the extended period. For example, receiving unit 201 may also receive signals from base station 100 outside the periodic extended period based on the second information. For example, receiving unit 201 may also receive from base station 100 third information (MAC CE, DCI, etc.) indicating the period of deactivation of the extended period. For example, receiving unit 201 may also receive signals from base station 100 during the periodic extended period based on the third information. For example, receiving unit 201 may also receive from base station 100 fourth information (MAC CE, DCI, etc.) indicating the period of activation of the extended period. For example, receiving unit 201 may also receive signals from base station 100 during one extended period based on the fourth information.

[0463] Regarding Proposal 5, for example, receiving unit 201 may also receive from base station 100 first information (RRC, etc.) related to a measurement (SSB measurement, etc.) using a measurement signal (SSB, etc.). For example, receiving unit 201 may also receive from base station 100 second information (RRC, SIB, MAC CE, DCI, etc.) indicating that a measurement is not performed during a portion of a periodic period (SMTC window, etc.) associated with the measurement. For example, receiving unit 201 may also receive, after receiving the second information from base station 100, information indicating that a measurement is performed during another portion of the periodic period (MAC CE, DCI, etc.). Receiving unit 201 may also receive signals from base station 100 during a portion of the periodic period.

[0464] Regarding Proposal 6, for example, receiving unit 201 may also receive from base station 100 first information (RRC, etc.) related to a measurement (SSB measurement, etc.) using a measurement signal (SSB, etc.). For example, receiving unit 201 may also receive from base station 100, after second information (request, etc.) is sent to base station 100, third information (RRC, SIB, MAC CE, DCI, etc.) indicating that a measurement will not be performed during a portion of a periodic period (SMTC window, etc.) associated with the measurement. For example, the second information (request, etc.) may also indicate that a measurement will not be performed during a portion or another portion of the periodic period, and receiving unit 201 may also receive from base station 100, after the second information is sent to base station 100, fourth information (RRC, SIB, MAC CE, DCI, etc.) indicating that a measurement will not be performed during a portion of the periodic period. For example, the second information (skip mode, etc., and request) may also indicate that no measurement will be performed during a portion of the periodic period. The receiving unit 201 may also receive, after the second information is sent to the base station 100, fourth information (RRC, SIB, MAC CE, DCI, etc.) indicating that no measurement will be performed during a portion of the periodic period. For example, the second information (skip mode, etc., and request) may also indicate that no measurement will be performed during a portion of the periodic period. The receiving unit 201 may also receive, after the second information is sent to the base station 100, fifth information (confirmation, etc.) confirming that no measurement will be performed during a portion of the periodic period. For example, the receiving unit 201 may also receive a signal from the base station 100 during a portion of the periodic period based on the third, fourth, second, and fifth information. For example, the second information (skip mode, etc., and notification) may also indicate that no measurement will be performed during a portion of the periodic period. The receiving unit 201 may also receive a signal from the base station 100 during a portion of the periodic period based on the second information.

[0465] The transmitting unit 202 transmits a UL signal to the base station 100. For example, under the control of the control unit 203, the transmitting unit 202 transmits a UL signal (e.g., the aforementioned request, notification, etc.).

[0466] Regarding Proposal 1, for example, if the timing of transmitting the signal overlaps with the period (measurement gap opportunity, SMTC window, etc.) associated with the measurement using the measurement signal (SSB, etc.), the transmitting unit 202 may also transmit the signal to the base station 100 at the aforementioned timing according to the judgment of the control unit 203.

[0467] Regarding Proposal 2, for example, the transmitting unit 202 may also transmit a signal to the base station 100 during a period of periodic extension (measurement gap opportunity, etc.) of a measurement (SSB measurement, etc.) that uses a measurement signal (SSB, etc.).

[0468] Regarding Proposal 3, for example, the transmitting unit 202 may also transmit second information to the base station 100 indicating that a measurement using a measurement signal (SSB, etc.) will not be performed (SSB measurement, etc.). For example, the transmitting unit 202 may also transmit a signal to the base station 100 during a portion of the periodically extended period (measurement gap opportunity, etc.) for the measurement based on the third, fourth, second, and fifth information. The second information may also indicate that a measurement will not be performed during a portion of the periodically extended period, and the transmitting unit 202 may also, based on the second information, not transmit a signal to the base station 100 during a portion of the periodically extended period.

[0469] Regarding Proposal 4, for example, the transmitting unit 202 may also, based on the second information, not transmit signals to the base station 100 during the periodic extension period (measurement gap opportunity, etc.) of measurements using measurement signals (SSB, etc.). For example, the transmitting unit 202 may also, based on the third information, transmit signals to the base station 100 during the periodic extension period. For example, the transmitting unit 202 may also, based on the fourth information, not transmit signals to the base station 100 during an extension period.

[0470] Regarding Proposal 5, for example, the transmitting unit 202 may also transmit a signal to the base station 100 during a periodic period (SMTC window, etc.) associated with a measurement (SSB measurement, etc.) that uses a measurement signal (SSB, etc.).

[0471] Regarding Proposal 6, for example, the transmitting unit 202 may also transmit second information to the base station 100 indicating that a measurement using a measurement signal (SSB, etc.) will not be performed (SSB measurement, etc.). For example, the transmitting unit 202 may also transmit a signal to the base station 100 during a periodic period (SMTC window, etc.) associated with the measurement using a measurement signal (SSB, etc.) based on the third, fourth, second, and fifth information. The second information may also indicate that a measurement will not be performed during a portion of the periodic period, and the transmitting unit 202 may also, based on the second information, not transmit a signal to the base station 100 during a portion of the extended periodic period.

[0472] The UL signal may also include, for example, uplink data signals and control information (e.g., UCI). For example, it may also include information related to the processing capabilities of the terminal 200 (e.g., UE capability). In addition, the UL signal may also include reference signals.

[0473] The channels used in transmitting UL signals include, for example, uplink data channels and uplink control channels. For instance, the uplink data channel includes a PUSCH (Physical Uplink Shared Channel), and the uplink control channel includes a PUCCH (Physical Uplink Control Channel). For example, terminal 200 uses the PUCCH to transmit uplink control information and the PUSCH to transmit uplink data signals to base station 100.

[0474] The reference signals included in the UL signal may include at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, reference signals such as DMRS and PTRS are used for demodulation of uplink data signals and are transmitted using an uplink channel (e.g., PUSCH).

[0475] The receiving unit 201 and the transmitting unit 202 can also be collectively referred to as the communication unit.

[0476] The control unit 203 controls the communication operation of the terminal 200, which includes the receiving processing in the receiving unit 201 and the transmitting processing in the transmitting unit 202.

[0477] For example, control unit 203 obtains data and control information from higher layers and outputs it to transmitting unit 202. Furthermore, control unit 203 may output data and control information received from receiving unit 201 to higher layers, for example.

[0478] For example, control unit 203 controls the transmission of information fed back to base station 100. The information fed back to base station 100 may include, for example, HARQ-ACK, Channel State Information (CSI), and Scheduling Request (SR). The information fed back to base station 100 may also be included in UCI.

[0479] Regarding Proposal 1, for example, when the timing of receiving or transmitting a signal overlaps with a period (measurement gap opportunity, SMTC window, etc.) associated with a measurement using a measurement signal (SSB, etc.), the control unit 203 determines whether to receive or transmit a signal or perform a measurement using a measurement signal. For example, the control unit 203 may also make the above determination based on information indicating the priority of the signal, period, and / or measurement, predefined conditions, etc. For example, the control unit 203 may also make the above determination when the signal is received or transmitted in a specific cell (Pcell, etc.) or carrier (CC, etc.).

[0480] Regarding Proposal 2, for example, the control unit 203 may also periodically set an extended period (measurement gap opportunity, etc.) for measurements using measurement signals (SSB, etc.) based on the first information. For example, the control unit 203 may also decide not to perform a portion of the periodically extended period of measurement based on the second information, and may not perform measurement during the determined portion of the periodically extended period.

[0481] Regarding Proposal 3, for example, the control unit 203 may also periodically set an extended period (measurement gap opportunity, etc.) for measurements using measurement signals (SSB, etc.) (SSB measurement, etc.) based on the first information. For example, the control unit 203 may also determine, based on the second, third, fourth, and fifth information, a portion of the periodically extended period during which the measurement is not performed, and may also refrain from performing the measurement during the determined portion of the periodically extended period.

[0482] Regarding Proposal 4, for example, the control unit 203 may periodically set the extended period (measurement gap opportunity, etc.) for measurements using measurement signals (SSB, etc.) based on the first information.

For example, the control unit 203 may activate the extended period based on the fourth information.

[0483] Regarding Proposal 5, for example, the control unit 203 may also periodically set a period (SMTC window, etc.) associated with measurements using measurement signals (SSB, etc.) (SSB measurement, etc.) based on the first information.

For example, the control unit 203 may also determine a portion of the periodic period during which measurements are not performed based on the second, third, fourth, and fifth information, and may also refrain from performing measurements during a portion of the determined periodic period.

[0485] Furthermore, the channels used in transmitting DL signals and UL signals are not limited to the examples described above. For instance, the channels used in transmitting DL signals and UL signals may also include RACH (Random Access Channel) and PBCH (Physical Broadcast Channel). RACH can also be used, for example, to transmit downlink control information (DCI) containing the Random Access Radio Network Temporary Identifier (RA-RNTI).

[0486] The above structure can reduce the impact of scheduling constraints caused by measurement.

[0487] <Summary of Implementation Methods>

[0488] As explained above, regarding Proposal 1, according to one aspect of this disclosure, a terminal is provided, comprising: a control unit that determines whether to receive or transmit the signal or to perform a measurement using the measurement signal when the timing of receiving or transmitting the signal overlaps with a period associated with a measurement using the measurement signal; and a communication unit that receives or transmits the signal at the determined timing.

[0489] The above structure allows signal reception or transmission to take precedence over measurement, thus reducing the impact of scheduling constraints related to measurement.

[0490] In one example, the control unit determines, based on information indicating the priority of the signal, the period, and / or the measurement, whether to receive or transmit the signal or to perform a measurement using the measurement signal.

[0491] With the above structure, by using priority as the control benchmark, it is possible to control whether to receive or send signals or to perform measurements.

[0492] In one example, the control unit determines, based on predefined conditions, whether to receive or send the signal or to perform a measurement using the measurement signal.

[0493] With the above structure, no signal exchange occurs between the terminal and the base station, thus reducing signaling overhead.

[0494] In one instance, the signal is received or transmitted within a specific cell.

[0495] By using the above structure, signaling overhead can be reduced and measurements can be performed more appropriately based on the cell by limiting the signal to a specific cell.

[0496] In one example, the signal is received or transmitted on a specific carrier wave.

[0497] By using the above structure, and by limiting the signal to a specific carrier, signaling overhead can be reduced, and measurements can be performed more appropriately according to the carrier.

[0498] According to one aspect of this disclosure, a communication method is provided in which a terminal performs the following: when the timing of receiving or transmitting a signal overlaps with a period associated with a measurement using a measurement signal, it determines whether to receive or transmit the signal or to perform a measurement using the measurement signal; and based on the determination, receives or transmits the signal at the timing.

[0499] The above structure allows signal reception or transmission to take precedence over measurement, thus reducing the impact of scheduling constraints related to measurement.

[0500] Furthermore, regarding Proposal 2, according to one aspect of this disclosure, a terminal is provided, comprising: a communication unit that receives from a base station first information relating to an extended period for a measurement using a measurement signal; and a control unit that, based on the first information, periodically sets the extended period for the measurement using the measurement signal, wherein the communication unit receives from the base station second information indicating that the measurement is not performed during a portion of the periodically extended period, and based on the second information, the control unit does not perform the measurement during a portion of the periodically extended period, and the communication unit performs signal reception or transmission with the base station.

[0501] With the above structure, it is possible to perform signal reception or transmission without performing measurements during a portion of the periodically extended period based on the second information from the base station, thus reducing the impact of scheduling constraints caused by measurement.

[0502] In one example, a portion of the periodic extension is N consecutive periods of the extension (N: an integer greater than 1).

[0503] The above structure can prevent measurements from being performed during periods when they are not suitable or when they are not required.

[0504] In one example, a portion of the periodic extension is the period during which the extension is included in the measurement of the non-execution period.

[0505] The above structure can prevent measurements from being performed during periods when they are not suitable or when they are not required.

[0506] In one example, the second information includes third information indicating whether the measurement is performed or not in each of the consecutive extended periods, a portion of the periodic extended periods being the extended periods corresponding to the third information indicating that the measurement is not performed in the consecutive extended periods.

[0507] The above structure avoids the need to perform measurements during various modes.

[0508] In one example, after receiving the second information, the communication unit receives from the base station fourth information indicating that the measurement is performed during another portion of the periodic extended period, the period of the periodic extended period being the extended period after receiving the second information and before receiving the fourth information.

Based on the third information, during the periodic extension, the control unit does not perform the measurement, and the communication unit performs signal reception or transmission with the base station.

Furthermore, notification of specific information (e.g., a "It is X" notification) is not limited to explicit notification, but can also be done implicitly (e.g., without notifying the recipient of that specific information).

[0590] The present disclosure has been described in detail above, but it will be apparent 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 ways without departing from the spirit and scope of the present disclosure as determined by the claims. Therefore, the description in this disclosure is for illustrative purposes only and is not intended to be restrictive in any way.

[0601] The names used for the parameters described above are not limiting names in any respect. Furthermore, the mathematical formulas used for these parameters sometimes differ from those explicitly disclosed in this disclosure. Various channels (e.g., PUCCH, PDCCH, etc.) and information elements can be identified by any suitable name; therefore, the various names assigned to these various channels and information elements are not limiting names in any respect.

There are also instances where terms such as macro cell, small cell, femtocell, and picocell are used to refer to base stations.

[0604] A base station can accommodate one or more (e.g., three) cells. When a base station accommodates multiple cells, its overall coverage area can be divided into several smaller areas, each of which can also provide communication services through a base station subsystem (e.g., a small indoor base station (Remote Radio Head (RRH))). Terms such as "cell" or "sector" refer to a portion or all of the coverage area of ​​at least one of the base station and base station subsystem providing communication services within that coverage area.

[0611] Furthermore, the base station in this disclosure can also be rewritten as a terminal. For example, embodiments of this disclosure can also be applied to structures where communication between the base station and the terminal is replaced by communication between multiple terminals (e.g., also referred to as D2D (Device-to-Device), V2X (Vehicle-to-Everything), etc.). In this case, it can also be configured such that the terminal has the functions of the base station described above. In addition, terms such as "uplink" and "downlink" can also be rewritten as terms corresponding to communication between terminals (e.g., "side").

The information service unit 2012 uses information obtained from external devices via the communication module 2013, etc., to provide various multimedia information and multimedia services to the occupants of the vehicle 2001.

[0618] The information service unit 2012 may include input devices (e.g., keyboard, mouse, microphone, switch, button, sensor, touch panel, etc.) that accept input from the outside, and output devices (e.g., display, speaker, LED light, touch panel, etc.) that implement output to the outside.

[0619] The driver assistance system unit 2030 comprises various devices used to provide functions for preventing accidents or reducing the driver's workload, such as millimeter-wave radar, LiDAR (Light Detection and Ranging), cameras, locators (e.g., GNSS), map information (e.g., high-definition (HD) mapping, autonomous vehicle (AV) mapping), gyroscope systems (e.g., IMU (Inertial Measurement Unit), INS (Inertial Navigation System)), AI (Artificial Intelligence) chips, and AI processors, and one or more ECUs that control these devices. Furthermore, the driver assistance system unit 2030 sends and receives various information via a communication module 2013 and implements driver assistance or autonomous driving functions.

[0620] The communication module 2013 can communicate with the microprocessor 2031 and the constituent elements of the vehicle 2001 via a communication port.

[0621] The communication module 2013, controlled by the microprocessor 2031 of the electronic control unit 2010, is a communication device capable of communicating with external devices. For example, it enables the transmission and reception of various information between external devices via wireless communication.

[0624] <Meaning and Explanation of Terms>

[0625] The terms "determining" and "determining" as used in this disclosure encompass a wide variety of actions. For example, "determining" or "determining" can include actions such as judging, calculating, computing, processing, deriving, investigating, searching (e.g., searching in a table, database, or other data structure), and ascertaining. Furthermore, "determining" or "determining" can include actions such as receiving (e.g., receiving information), transmitting (e.g., sending information), inputting, outputting, and accessing (e.g., accessing data in memory). Additionally, "determining" or "determining" can include actions such as resolving, selecting, choosing, establishing, and comparing. That is, "judgment" and "decision" can include situations where certain actions are regarded as having been "judged" or "decided". In addition, "judgment (decision)" can also be rewritten as "assuming", "expecting", "considering", etc.

[0626] The terms “connected,” “coupled,” or all variations thereof, refer to all direct or indirect connections or combinations between two or more elements, and can include cases where there is one or more intermediate elements between two mutually “connected” or “coupled” elements. The connection or combination between elements can be physical, logical, or a combination thereof. For example, “connected” can also be rewritten as “access.” In the context of this disclosure, it is possible to consider two elements being mutually “connected” or “coupled” using at least one or more wires, cables, or printed electrical connections, and as several non-limiting and non-exclusive examples, using electromagnetic energy with wavelengths in the wireless frequency domain, microwave region, and light (both visible and invisible) region.

[0627] <Reference Signal>

[0628] The reference signal can also be simply referred to as RS (Reference Signal), and may also be called a pilot depending on the standard applied.

[0629] <The meaning of "based on">

[0630] As used in this disclosure, the term "based on" does not mean "based on only" unless otherwise specified. In other words, the term "based on" means both "based on only" and "based on at least".

[0631] <"First", "Second">

[0632] Any reference to elements using the designations "first," "second," etc., as used in this disclosure does not comprehensively limit the quantity or order of these elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Therefore, references to the first and second elements do not imply that only two elements may be used, or that the first element must take precedence over the second element in some form.

[0633] <Unit>

[0634] Alternatively, the term "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0635] <Open format>

[0636] In this disclosure, the terms “include,” “including,” and variations thereof, as well as the term “comprising,” refer to inclusion. Furthermore, the term “or” as used in this disclosure does not mean XOR.

[0637] <Time units such as TTI, frequency units such as RB, and radio frame structure>

[0638] A wireless frame can also consist of one or more frames in the time domain. These frames can also be referred to as subframes in the time domain. Furthermore, a subframe can also consist of one or more time slots in the time domain. A subframe can also be a fixed time length (e.g., 1 ms) independent of the parameter set (numerology).

[0639] A parameter set can also be a set of communication parameters applied in at least one of the transmission and reception of a signal or channel. For example, a parameter set can also represent at least one of the following: subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering processing performed by the transmitter and receiver in the frequency domain, and specific windowing processing performed by the transmitter and receiver in the time domain.

[0640] In the time domain, a time slot can also be composed of one or more symbols (OFDM (Orthogonal Frequency Division Multiplexing) symbols, SC-FDMA (Single Carrier Frequency Division Multiple Access) symbols, etc.). A time slot can also be a time unit based on a set of parameters.

[0641] A time slot can also contain multiple mini-time slots. Each mini-time slot can also consist of one or more symbols in the time domain. Furthermore, a mini-time slot can also be called a sub-time slot. A mini-time slot can also consist of fewer symbols than a time slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a mini-time slot can also be called PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using mini-time slots can also be called PDSCH (or PUSCH) mapping type B.

[0642] Radio frames, subframes, time slots, mini-time slots, and symbols all represent time units for transmitting signals. Radio frames, subframes, time slots, mini-time slots, and symbols can also be referred to by their respective other names.

[0643] For example, a subframe can also be called a Transmission Time Interval (TTI), multiple consecutive subframes can also be called a TTI, and a time slot or a mini-time slot can also be called a TTI. That is, at least one of a subframe and a TTI can be a subframe in existing LTE (1ms), a period shorter than 1ms (e.g., 1-13 symbols), or a period longer than 1ms. In addition, the unit representing TTI may not be called a subframe, but a time slot, mini-time slot, etc.

[0644] Here, TTI refers, for example, to the smallest unit of time for scheduling in wireless communication. For instance, in an LTE system, the base station schedules radio resources (frequency bandwidth, transmit power, etc., available to each user terminal) in TTI units. However, the definition of TTI is not limited to this.

[0645] TTI can also be a unit of time for transmitting channel-coded data packets (transmission blocks), code blocks, codewords, etc., and can also be a unit of processing such as scheduling and link adaptation. In addition, when a TTI is given, the actual time interval (e.g., the number of symbols) mapped to transmission blocks, code blocks, codewords, etc. can be shorter than the TTI.

[0646] Additionally, where a time slot or a mini-time slot is referred to as a TTI, more than one TTI (i.e., more than one time slot or more than one mini-time slot) can also serve as the minimum time unit for scheduling. Furthermore, the number of time slots (mini-time slots) constituting the minimum time unit of the schedule can also be controlled.

[0647] A TTI with a duration of 1ms can also be referred to as a normal TTI (TTI in LTE Rel.8-12), standard TTI, long TTI, normal subframe, standard subframe, long subframe, time slot, etc. A TTI shorter than a normal TTI can also be referred to as a shortened TTI, short TTI, partial TTI (partial or fractional TTI), shortened subframe, short subframe, mini time slot, sub-time slot, time slot, etc.

[0648] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) can also be rewritten as a TTI with a duration of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) can also be rewritten as a TTI with a duration of less than a long TTI but more than 1 ms.

[0649] A resource block (RB) is a unit of resource allocation in both the time and frequency domains. In the frequency domain, it can also contain one or more consecutive subcarriers. The number of subcarriers in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers in an RB can also be determined based on the parameter set.

[0650] Furthermore, the time domain of an RB can also contain one or more symbols, or it can be the length of a time slot, a mini-time slot, a subframe, or a TTI. A TTI, a subframe, etc., can also be composed of one or more resource blocks.

[0651] In addition, one or more RBs can also be referred to as Physical Resource Blocks (PRBs), Sub-Carrier Groups (SCGs), Resource Element Groups (REGs), PRB pairs, RB pairs, etc.

[0652] Furthermore, a resource block can also consist of one or more resource elements (REs). For example, an RE can also be a radio resource area consisting of a subcarrier and a symbol.

[0653] The Bandwidth Part (BWP) (also known as partial bandwidth, etc.) can also represent a subset of consecutive common resource blocks (RBs) used for a certain parameter set in a certain carrier. Here, common RBs can also be determined by the index of RBs based on the common reference point of that carrier. PRBs can also be defined in a BWP and appended with numbers within that BWP.

[0654] A BWP can also include a UL BWP and a DL BWP. For a UE, one or more BWPs can also be set within a single carrier.

[0655] At least one of the configured BWPs can be active, and the UE may not intend to transmit or receive specific signals / channels outside of the active BWPs. Furthermore, the terms "cell," "carrier," etc., in this disclosure can be rewritten as "BWP."

[0656] The structures described above, such as radio frames, subframes, time slots, mini-time slots, and symbols, are merely illustrative. For example, the number of subframes contained in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots contained within a time slot, the number of symbols and RBs contained in a time slot or mini-time slot, the number of subcarriers contained in an RB, and the number of symbols in a TTI, symbol length, and cyclic prefix (CP) length can be varied in many ways.

[0657] <Maximum Transmit Power>

[0658] The term "maximum transmit power" as used in this disclosure may refer to the maximum value of the transmit power, the nominal maximum transmit power (the nominal UE maximum transmit power), or the rated maximum transmit power (the rated UE maximum transmit power).

[0659] <Article>

[0660] In this disclosure, for example, in cases where articles are added through translation, such as a, an, and the in English, the disclosure may also include cases where the noun following these articles is in a plural form.

[0661] <"Differences">

[0662] In this disclosure, the term "A is different from B" can also mean "A and B are different from each other." Additionally, the term can also mean "A and B are each different from C." Terms such as "separate" and "combined" can also be interpreted in the same way as "different."
