Description

Technical Field

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

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

[0003] In 5G, technologies that meet requirements such as high-capacity systems, high-speed data transmission, low latency, simultaneous connection of multiple terminals, low cost, and power saving are being researched (e.g., non-patent literature 1).

[0004] With the expansion of mobile communication systems as described above, it is hoped that the combination of the real world and the virtual world (virtual content) will be possible. The utilization and popularization of XR (extended reality) such as VR (virtual reality), AR (augmented reality), and MR (mixed reality) are being discussed in 3GPP for Release 19 (for example, see Non-Patent Document 2).

[0005] Related to XR extensions, for example, extensions related to Measurement Gap (MG) and scheduling constraints are being widely discussed.

[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, determine the future scope of the standard that may be included to reduce the impact on capacity and individual terminals.

[0009] Non-patent document 1: 3GPP TS 38.300 V17.6.0 (2023-09)

[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 current wireless communication systems, measurements using synchronization signal blocks (SSB) are employed (SSB-based measurement).

[0012] To perform SSB measurements, the terminal is notified of measurement-related timing settings (SMTC: SSB-based Measurement Timing Configuration). The terminal then performs measurements on the signal based on the object being measured within the configured SMTC window. Furthermore, to perform functions such as switching the operating frequency (RF: Radio Frequency), settings related to measurement intervals can be notified to the terminal for use in SSB measurements.

[0013] Due to the periodicity of XR services, when the transmission and reception of signals involved in XR services overlap with the SMTC window and measurement gap, the signal cannot be scheduled, which may lead to problems such as capacity loss caused by scheduling limitations of accompanying measurements.

[0014] Furthermore, in current wireless communication systems, other measurements, such as those using Channel State Information Reference Signal (CSI-RS) (CSI-RS based measurement), are also employed, and the aforementioned problems may occur in various measurements. Moreover, these problems may also occur in the transmission and reception of signals other than those involved in XR services.

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

[0016] One aspect of this disclosure relates to a terminal comprising: a communication unit that receives first information from a base station, the 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 a measurement using the measurement signal, the communication unit receiving second information from the base station indicating activation of the extended period, and based on the second information, the control unit performing the measurement during the periodic extended period, and the communication unit not performing signal reception or transmission with the base station.

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

[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 and includes a Next Generation-Radio Access Network 20 (hereinafter NG-RAN20) 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 known as 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). Alternatively, when there is no need to distinguish between each of 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... Figure 1 The example shown.

[0052] NG-RAN20 actually includes multiple NG-RAN nodes, specifically gNBs (or ng-eNBs), connected 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 and perform 5G-compliant wireless communication with UE200. gNB100A, gNB100B, and UE200 can correspond to: MIMO (Multiple-Input Multiple-Output) which generates a more directional beam BM by controlling the wireless signals transmitted from multiple antenna elements; carrier aggregation (CA) which aggregates multiple component carriers (CC); and dual connectivity (DC) which enables communication between the UE and two NG-RAN nodes.

[0054] Furthermore, the wireless communication system 10 can correspond to multiple frequency ranges (FR). 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 correspond to FR1 and FR2. The frequency bands of each FR are described below, for example.

[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 use SCS of 60kHz or 120kHz (including 240kHz), as well as a bandwidth (BW) of 50~400MHz.

[0058] Alternatively, SCS can also be interpreted as a numerology. The numerology 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 exceeding 52.6 GHz and not exceeding 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 (wider) the SCS, the shorter the symbol period (and time slot period). However, the SCS is not limited to... 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 does not necessarily have to be 14 symbols (for example, it could be 28 or 56 symbols, etc.). Moreover, the number of time slots in each subframe can 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] gNB100 sends control information, configuration information, etc. as downlink (DL) signals to UE200.

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

[0065] The channels used in transmitting DL signals include, for example, data channels and control channels. For instance, data channels may include the Physical Downlink Shared Channel (PDSCH), and control channels may include the Physical Downlink Control Channel (PDCCH). For example, for UE200, gNB100 uses PDCCH to transmit control information and PDSCH to transmit DL data signals. 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, for example, at least one of 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 in the demodulation of 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, UE200 sends control information, data signals, and UE200 terminal capability information to gNB100 as UL signals.

[0071] The channels used in transmitting UL signals include, for example, data channels and control channels. For instance, the data channel may include the Physical Uplink Shared Channel (PUSCH), and the control channel may include the Physical Uplink Control Channel (PUCCH). For example, UE200 uses PUCCH to transmit control information and uses 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 the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRS, RS, and PRS for location information. For example, reference signals such as DMRS and PTRS are used in the demodulation of the UL data signal and are transmitted using PUSCH.

[0073] <State of discussion related to XR>

[0074] XR presents attractive use cases for future wireless communication systems. On the other hand, XR also brings challenges that need to be studied and addressed. As one of these challenges, XR extensions are being discussed in 3GPP for Release 19 (see, for example, non-patent literature 2), with extensive discussions on extensions related to measurement gaps and scheduling constraints.

[0075] <About SSB and SSB Measurement>

[0076] Among the signals and / or channels transmitted from the base station to the terminal, there are periodically transmitted signals and / or channels. In examples of such signals and / or channels, a synchronization signal block (SSB) is included.

[0077] SSB is used by the terminal for measurements such as 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] The terminal is notified of the measurement-related timing settings (SMTC) for SSB measurements. The SMTC may also 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, for purposes such as switching the operating frequency (RF: Radio Frequency), settings related to the measurement gap can be notified to the terminal for use in SSB measurements. The measurement gap is an extended period for measurement, which can be appended before and after the SMTC window. Settings related to the measurement gap may also include length, period, etc.

[0080] In addition, the RRM measurement example also includes CSI-RS based measurements (CSI-RS measurements).

[0081] In NR, the following RRM measurement is used, which includes SSB measurement and CSI-RS measurement, with or without measurement gap.

[0082] (1) Intra-frequency measurement

[0083] (2) Inter-frequency measurement

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

[0085] <Scheduling constraints related to RRM measurements>

[0086] Regarding in-frequency SSB measurements, 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 are described in the following locations in the current standard.

[0087] SSB measurement within a frequency range without a measurement gap: Clause 9.2.5.3 of TS 38.133 (in short, under certain conditions, a scheduling constraint is imposed on the SSB symbol being measured within the SMTC window or on all symbols within the SMTC window).

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

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

[0090] Regarding inter-frequency SSB measurements, 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 are described in the current standard at the following location.

[0091] Inter-frequency SSB measurement without measurement gap: Clause 9.3.5.3 of TS 38.133 (in short, under certain conditions, a scheduling constraint is imposed on the SSB symbol being measured within the SMTC window or on all symbols 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 the SMTC window for all Measurement Occasions (MOs) or the union of all symbols within the SMTC window for all MOs).

[0093] Frequency-interval SSB measurement accompanying the measurement gap: Clause 9.1.2 of TS 38.133

[0094] Regarding in-frequency CSI-RS measurements, scheduling restrictions (terminal operation restrictions) related to in-frequency CSI-RS measurements without accompanying measurement gaps are described in the current standard at the following location.

[0095] CSI-RS measurements within a frequency range without measurement gaps: Clause 9.10.2.6 of TS 38.133 (in short, under certain conditions, scheduling constraints are imposed on the set CSI-RS symbols).

[0096] Regarding inter-frequency CSI-RS measurements, the scheduling constraints (terminal operation constraints) associated with inter-frequency CSI-RS measurements accompanying measurement gaps are described in the current standard at the following location.

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

[0098] Due to the periodicity of XR services, if the SMTC window, measurement gap, and the transmission and reception of signals involved in the XR service overlap, the signal cannot be scheduled, which may lead to problems such as capacity loss caused by scheduling limitations of accompanying measurements.

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

[0100] The aforementioned problems can 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 services.

[0101] Currently, although research is being conducted on extensions to scheduling constraints, the specific operations related to the control used to implement these extensions have not been fully studied.

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

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

[0104] Proposal 1: Support terminals in prioritizing channel / signal transmission / reception over RRM measurements based on one or more specific conditions.

[0105] Proposal 2: Support skipping or deactivating measurement gaps in base station notifications

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

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

[0108] Proposal 5: Support base station notification skipping or deactivation of RRM measurements

[0109] Proposal 6: Support terminal reporting requests / notifications 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 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 be applied to any measurement (e.g., RRM measurement), including intra-frequency SSB and / or CSI-RS measurements with and / or without measurement gaps, 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 with measurement gaps, and / or inter-frequency SSB and / or CSI-RS measurements.

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

[0113] In this application, the word " / " can 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", "not allowing receiving / sending", "not performing receiving / sending", "restricting receiving / sending", "assuming that receiving / sending is impossible", etc.

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

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

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

[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 assumed that scheduling constraints are not applied)", etc.

[0119] <Proposal 1>

[0120] The following describes how a terminal supports prioritizing channel / signal transmission / reception over RRM measurement based on one or more conditions (Proposal 1). Processing related to prioritizing channel / signal transmission / reception over RRM measurement, and / or prioritizing RRM measurement and channel / signal transmission / reception, can also be referred to as priority processing, etc.

[0121] For one or more conditions that take precedence over RRM measurements in channel / signal transmission / reception, the following options 1 / 2 may also apply.

[0122] [Option 1]

[0123] One or more conditions can also be predefined. For example, a predefined rule as a predefined condition can define when and which signal / channel (transmission / reception) can take precedence over RRM measurements (with or without measurement gaps). Such conditions / rules can also be predefined in the 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 received / transmitted DL / UL channel / signal on one or more CCs, and the DL / UL channel / signal overlaps with the measurement gap, or overlaps with the SMTC window (within which the measured SSB symbol is located), or overlaps with the measured CSI-RS symbol used 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 (e.g., during the measurement gap / SMTC window) and does not perform RRM measurement.

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

[0126] Condition A2: The DL / UL channel / signal is scheduled / triggered by DCI (or activated by DCI, or set by RRC), or scheduled / triggered by 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 context (e.g., in TN / NTN, in FR1 / FR2, in licensed / unlicensed bands, in FDD / TDD, etc.).

[0131] Condition A7: RRM measurement is performed with or without a 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 situations 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 by 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., they can be Pcell (primary cell) / Pscell (primary / secondary cell) / Scell ​​(secondary cell)), set by RRC (e.g., they can be a list of CCs, and priority processing can be activated / deactivated on a per-CC basis), or they can be 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 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 to prioritize RRM measurements based on the priority state value of the DL / UL channel / signal and / or RRM measurement (and / or measurement gap).

[0140] As an example of Option 2 (Example 1), Terminal 200 can also determine whether to prioritize transmitting / receiving the DL / UL channel / signal or prioritizing 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 to be received / transmitted on one or more CCs, and the DL / UL channel / signal overlaps with the measurement gap, and the priority status value of the DL / UL channel / signal is greater (or smaller) than the priority status value of the measurement gap, Terminal 200 performs the reception / transmission of the DL / UL channel / signal and does not perform RRM measurement in the measurement gap. Otherwise, Terminal 200 performs RRM measurement or needs to perform RRM measurement in the measurement gap and does not receive / transmit the DL / UL channel / signal.

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

[0143] Figure 6 This illustrates another example of how priority status values ​​based on DL / UL channels / signals and RRM measurements determine whether to prioritize the transmission / reception of minimal DL / UL channels / signals or to prioritize RRM measurements. For example... Figure 6 As shown, when the URLLC / XR PDSCH 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 / XR PDSCH and measures the SSB during the measurement gap / SMTC window.

[0144] Additionally, 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 also be defined for different conditions such as conditions A1 / A2 / A3 / A4 / A5 proposed 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 each of the above examples (Example 1 and Example 2), the aforementioned one or more CCs (or carriers) can be defined by a standard (e.g., it can be Pcell / Pscell / Scell), set by RRC (e.g., a list of CCs can also be set, and priority processing can be activated / deactivated for each CC), or one or more CCs in a specific frequency range (e.g., FR1 / FR2).

[0147] [A variation of Proposal 1]

[0148] Whether priority processing is activated can be defined by the standard (e.g., always activated (in a 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 accompanying measurement gaps, and / or intra-frequency SSB / CSI-RS measurements / inter-frequency SSB / CSI-RS measurements without accompanying 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 The operation example of terminal 200 is explained.

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

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

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

[0156] Based on Proposal 1, channel / signal transmission / reception can be prioritized over RRM measurements based on conditions, thus reducing the impact of measurement-related scheduling constraints.

[0157] <Proposal 2>

[0158] As Proposal 2, it explains the notification that the base station supports skipping or deactivating measurement gaps.

[0159] The operation of terminal 200 related to skipping or deactivating measurement gaps can 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 receive / transmit DL / UL channels / signals during the measurement gap opportunity without performing RRM measurements (and / or positioning reference signal (PRS) measurements).

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

[0162] [Alternative 1 (Alt 1)]

[0163] Skipping or deactivating measurement gap opportunities can also be notified via semi-static notifications based on RRC or SIB. For example, RRC can set a measurement gap skipping pattern, and SIB can notify of the measurement gap skipping pattern. When multiple measurement gap settings are set, the measurement gap skipping pattern can be common to all of the multiple 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 portion of the extended period used 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 non-skipped measurement gaps, applying scheduling constraints defined in the current standard. During measurement gaps that are set / notified to be skipped, terminal 200 can receive / transmit DL / UL channels / signals without performing RRM measurements.

[0165] Figure 7 An example of a notification skipping measurement gap opportunity based on Alternative 1 (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", in the illustrated measurement gap opportunities, the first measurement gap opportunity is set to not skip (activated), the second measurement gap opportunity is set to skip (deactivated), the third measurement gap opportunity is set to not skip (activated), and the fourth measurement gap opportunity is set to not skip (activated). Therefore, terminal 200 decides to skip the second measurement gap opportunity, and terminal 200 can receive / transmit DL / UL channels / signals without performing RRM measurements during the second measurement gap.

[0166] [Alternative 2 (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 (within a portion of the extended period used for measurement) that no measurement will be performed. 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 alternatives 2-1 / 2-2 / 2-3 / 2-4 (Alt 2-1 / 2-2 / 2-3 / 2-4).

[0168] • Alternative 2-1 (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 Alternative 2-1 (Alt 2-1), the initial measurement gap opportunity that is skipped can also be the initial measurement gap opportunity after X symbols / slots of the final symbol / slot of the DCI used for notification (or, the HARQ-ACK corresponding to the PDSCH (which includes 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 be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0171] Furthermore, the value of N can be defined by the standard (e.g., N=1), set by RRC, or notified by the DCI / MAC CE used for the notification.

[0172] Measurement gap opportunities not included in the N consecutive measurement gap opportunities are not skipped. Terminal 200 needs to perform RRM measurements during the non-skipped measurement gap opportunities, applying the scheduling constraints defined in the current standard. During the N consecutive measurement gap opportunities, terminal 200 may not perform RRM measurements but instead receive / transmit DL / UL channels / signals.

[0173] Figure 8 This is an example of skipping notifications based on the measurement gap opportunity of Alternative 2-1 (Alt 2-1), and shows N DCI notifications skipped (in Figure 8 The 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 decide to skip the initial and second measurement gap opportunities illustrated, during which RRM measurements are not performed, but DL / UL channels / signals are received / transmitted.

[0174] • Alternative 2-2 (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 Alternative 2-2 (Alt 2-2), the start of the skip window can also be X symbols / slots after the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK corresponding to 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 be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0177] Furthermore, the length of the skip window can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

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

[0179] Figure 9 This is an example of a notification to skip measurement gap opportunities based on Alternative 2-2 (Alt 2-2), and it illustrates an example of DCI notification skipping measurement gap opportunities contained within the skip window. In this example, the illustrated initial measurement gap opportunity and the second measurement gap opportunity are skipped. Therefore, terminal 200 can decide to skip the illustrated initial measurement gap opportunity and the second measurement gap opportunity, during which RRM measurements are not performed, but DL / UL channels / signals are received / transmitted.

[0180] • Alternatives 2-3 (Alt 2-3)

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

[0182] As an example of Alternative 2-3 (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. A bit value of "0" can also represent "not skipped (not skipped)," and a bit value of "1" can also represent "skipped (skipped)." For measurement gap opportunities notified as "skipped," terminal 200 can receive / transmit DL / UL channels / signals without performing RRM measurements or applying the scheduling restrictions defined in the current standard. On the other hand, for measurement gap opportunities notified as "not skipped," terminal 200 needs to perform RRM measurements and apply the scheduling restrictions defined in the current standard for measurement gap opportunities that are not skipped.

[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 of the final symbol / slot of the notification DCI (or, the HARQ-ACK corresponding to the PDSCH corresponding to the notification MAC CE). 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 be defined by the standard, set by RRC, or notified by the notification DCI / MAC CE.

[0184] Furthermore, the value of N can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0185] Figure 10 This is an example of skipping notifications based on the measurement gap opportunities of Alternate 2-3 (Alt 2-3), and shows how 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 decide to skip the second measurement gap opportunity shown, in which RRM measurement is not performed, but DL / UL channel / signal is received / transmitted.

[0186] • Alternatives 2-4 (Alt 2-4)

[0187] The DCI or MAC CE can also notify that the set measurement gap is deactivated before the terminal 200 receives another DCI or MAC CE to activate the measurement gap. In other words, if the terminal 200 receives a DCI or MAC CE to deactivate the measurement gap, the measurement gap can remain deactivated (in a deactivated state) until another DCI or MAC CE to activate the measurement gap is received. The DCI or MAC CE that deactivates the measurement gap can also be referred to as information indicating (in another) part of the extended period used for measurement) that a measurement is being performed.

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

[0189] When multiple measurement gaps or measurement gap settings are configured, the DCI or MAC CE can either notify the deactivation of all of the configured measurement gaps or measurement gap settings, or notify the deactivation of a specific measurement gap or measurement gap setting. For example, when the DCI or MAC CE notifies the deactivation 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 an alternative DCI or MAC CE from base station 100 that notifies the activation of the measurement gap, terminal 200 may also decide to activate the measurement gap opportunity starting from Y symbols / slots after the final symbol / slot of the alternative DCI (or, the HARQ-ACK corresponding to the PDSCH corresponding to the alternative MAC CE). The value of Y can be defined by the standard, set by RRC, or notified by the alternative DCI / MAC CE.

[0191] Figure 11This is an example of skipping measurement gap opportunities based on Alternative 2-4 (Alt 2-4), and illustrates an example where another DCI notifies the activation of a measurement gap after the DCI has notified the deactivation of the measurement gap. In this example, the DCI notifies the deactivation of the measurement gap before the initial measurement gap opportunity shown in the illustration. Therefore, subsequent measurement gap opportunities that meet the above conditions are deactivated / skipped. In this example, the first three measurement gap opportunities from the initial measurement gap opportunity until the first DCI is received are skipped. After the third measurement gap opportunity, another DCI notifies the activation of the measurement gap. Therefore, subsequent measurement gap opportunities (furthermore, until another DCI notifies the deactivation of the measurement gap) are not activated / skipped. Thus, terminal 200 can decide to skip the initial to third measurement gap opportunities shown in the illustration, and receive / transmit DL / UL channels / signals during these measurement gap opportunities without performing RRM measurements. On the other hand, terminal 200 decides not to skip the last measurement gap opportunity shown in the figure, and needs to perform RRM measurement in that measurement gap opportunity. In the measurement gap opportunities that are not skipped, the scheduling constraints defined in the current standard are applied.

[0192] • Variations of Alternative 2-1 / 2-2 / 2-3 / 2-4 (Alt 2-1 / 2-2 / 2-3 / 2-4)

[0193] Dynamic notifications based on DCI or MAC CE can be applied either to more than one specific measurement gap type (e.g., FR1 measurement gap or FR2 measurement gap) 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 of multiple measurement gap settings. That is, dynamic notifications based on DCI or MAC CE can also be common notifications 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] In addition, in this application, the measurement gap (opportunity) may also be referred to as the extended period or interval used 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) or a (new) information element that is the same as the RRC parameter.

[0203] In step S22, the terminal 200 periodically sets the extended period for the measurement 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 period after the periodic extension. For example, the second information may also be a semi-static notification as described in Alternative 1 (Alt 1) / a dynamic notification as described in Alternative 2 (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 instead performs signal reception or transmission between base stations.

[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 measurement-related scheduling constraints.

[0207] <Proposal 3>

[0208] As Proposal 3, it describes how the terminal supports reporting requests / notifications for skipping or deactivating measurement gaps.

[0209] Terminal 200 can also report a request / notification to skip or deactivate a measurement gap to base station 100 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 the measurement gap can be set by RRC or notified by scheduling DCI. The request / notification to skip or deactivate the measurement gap can also be referred to as information indicating (within a portion of the extended period for measurement) that measurement will not be performed, etc.

[0210] Reports of requests / notifications to skip or deactivate measurement gaps can be periodic, and / or semi-persistent, and / or non-periodic, and / or triggered by events. In the case of such reports being triggered by events, the event could, for example, indicate a situation where measurement is not required. For example, the event could be a measurement period in which the received quality of the measurement signal (SSB, etc.) is measured a specific number of times within a specific range during multiple consecutive measurement periods (SMTC windows, etc.), or a measurement period in which the received quality of the measurement signal is measured is continuously maintained for a specific number of times.

[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 trigger skipping or deactivating a measurement gap to base station 100. After reporting the request to base station 100, terminal 200 may also monitor / receive a notification from base station 100 notifying it of skipping or deactivating the measurement gap (the notification is sent from base station 100). In option 1, how to skip the measurement gap may also depend on the 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 measurement gaps can also follow the above-mentioned Proposal 2 (including options, Alternate (Alt) 1 / 2 (Alternate 2-1 (Alt 2-1) ~ Alternate 2-4 (Alt 2-4)). That is, as described in Proposal 2 above, the operation of terminal 200 when skipping measurement gap opportunities can also follow the notification from base station 100.

[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 may also report requests to skip or deactivate measurement gaps, as well as information related to requested / suggested skipping occasions (skipped measurement gap opportunities), to base station 100. In this case, terminal 200 also requests / suggests skipped measurement gap opportunities.

[0218] Option 2 requires notification from base station 100 regarding how to skip the measurement gap, or confirmation (allowance, permission) of the request from base station 100 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 in more detail in [reference needed]. Figure 13 as well as Figure 14 And will be discussed later.

[0219] The content of a request based on 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 gaps (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 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 measurement gap opportunity that is skipped in this way. The value of X can be defined by the standard, set by RRC, or notified by the request.

[0222] Furthermore, the value of N can be defined by the standard (e.g., N=1), set by the 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 X symbols / slots after 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.

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

[0226] Option 2-c: A skip mode related to whether to skip or not skip for each of N consecutive measurement gap opportunities (N being 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. A bit value of "0" can also represent "not skipped (not skipped)", a bit value of "1" can also represent "skipped (skipped)", and a bit value of "0" can also represent "skipped (skipped)".

[0228] The initial measurement gap opportunity among N consecutive measurement gap opportunities can also be the initial measurement gap opportunity after X symbols / slots following 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 to be skipped in this way. The value of X can be defined by the standard, set by RRC, or notified by the request.

[0229] Furthermore, the value of N can be defined by the standard, set by the RRC, or notified by the request.

[0230] Option 2-d: The set measurement gap can also be deactivated (remained deactivated) until terminal 200 sends a request to activate the measurement gap. The request to activate the measurement gap can also be referred to as information indicating (in another) part of the extended period used for measurement) that a measurement will be performed.

[0231] Terminal 200 can also decide to deactivate the measurement gap opportunity starting from X symbols / slots after the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). The value of X can be defined by the 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 another request to activate the measurement gap, terminal 200 may also decide to activate the measurement gap opportunity starting from Y symbols / slots after the final symbol / slot of the other request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the other request). The value of Y can be defined by the 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 requested by terminal 200 can also be one or more of the following options 1 to 3 (Alt 1 to Alt 3).

[0235] Alternative 1 (Alt 1)

[0236] The content requested by terminal 200 can also be content for all measurement gap settings / types.

[0237] Alternative 2 (Alt 2)

[0238] The content of the request based on terminal 200 can also be content set for more than one specific measurement gap, and more than one measurement gap setting as an object can also be included in the request.

[0239] Alternative 3 (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] After terminal 200 reports a request to base station 100 to skip or deactivate the measurement gap (e.g., following the request in options 2-a / 2-b / 2-c / 2-d), the operation of terminal 200 can also follow the following options 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 measurement gaps can also follow the above-mentioned Proposal 2 (including options, Alternate (Alt) 1 / 2 (Alternate 2-1 (Alt 2-1) ~ Alternate 2-4 (Alt 2-4)). That is, as described in Proposal 2 above, the operation of terminal 200 when skipping measurement gap opportunities can also follow the notification from base station 100.

[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 the confirmation is received (in the monitoring window), terminal 200 can skip the measurement gap opportunity as requested. On the other hand, if the confirmation is not received (in the monitoring window), terminal 200 cannot skip the measurement gap opportunity as requested.

[0248] The aforementioned monitoring window can also be determined as follows.

[0249] • The monitoring window can start either as the first symbol / slot after the K symbols / slots of the request, or as the first symbol / slot monitored by the PDCCH 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 the standard, set by RRC, or reported in the request.

[0251] For example, such as Figure 14 As shown, after sending the request and a prompt 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 (prompted) (e.g., based on the requested (prompted) skip mode).

[0252] As a variation of option 2-2, if the request based on terminal 200 is a request for multiple measurement gap settings / types, the confirmation of base station 100 can also follow the following alternative 1 / 2 (Alt 1 / 2).

[0253] Alternative 1 (Alt 1): A single confirmation is only required for requests that specify multiple measurement gap settings / types.

[0254] Alternative 2 (Alt 2): Terminal 200 can also assume (receive) confirmation according to each measurement gap setting / type.

[0255] [Option 3]

[0256] Terminal 200 may also report a notification to base station 100 regarding skipping or deactivating a measurement gap opportunity. In option 3, without 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 based on 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 rewritten as "notification".

[0258] The operation of terminal 200 after reporting a notification to base station 100 to skip or deactivate the measurement gap (e.g., following the notification of options 2-a / 2-b / 2-c / 2-d of proposal 3 above) can also be 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 current standard (terminal 200 can 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 current standard in 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 does not receive the notification and acknowledgment from the base station 100, but skips the measurement gap opportunity as notified (e.g., based on the notified skip mode).

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

[0263] In the presence of multiple measurement gap settings / types, terminal 200 may report a request / instruction to base station 100 without including details related to the measurement gap setting / type to which the request / notification for skipping or deactivating the measurement gap is intended (either reporting a request / notification for skipping or deactivating the measurement gap to base station 100 for all of the multiple measurement gap settings / types), or it may report to base station 100 information related to the measurement gap setting intended to be skipped or deactivated or a specific measurement gap type (e.g., each UE / FR, FR1 / FR2, etc.).

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

[0265] <Operation example>

[0266] Next, refer to Figure 22 The operation example of terminal 200 is explained.

[0267] In step S31, terminal 200 receives from base station 100 first information related to the extended period of measurement using measurement signals. 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 extended period for the measurement 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, in response to the transmission of the second information in step S33, the terminal 200 does not perform measurements during a portion of the periodically extended period, but instead performs signal reception or transmission between base stations.

[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 periodically extended period (indicating that no measurement will be performed during a portion of the periodically extended period); sometimes, as described in option 2-2, base station 100 sends an acknowledgment that no measurement will be performed during a portion of the periodically extended period; and sometimes, as described in option 3, no communication 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, thus reducing the impact of measurement-related scheduling constraints.

[0273] <Proposal 4>

[0274] As Proposal 4, it explains the support for periodic / semi-continuous / non-periodic measurement gaps.

[0275] In the aforementioned proposals 1-3, the assumption was that the measurement gap was periodic. However, the measurement gap is not limited to periodic measurement gaps. Specifically, the measurement gap may 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 always be activated (i.e., always in an effective 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 gap, semi-continuous measurement gap, and non-periodic measurement gap to existing RRM measurement setting information elements (e.g., MeasGapConfigIE), or (new) information elements for periodic measurement gaps that are the same as the information element.

[0277] Regarding semi-persistent measurement gaps, these gaps can also be activated / deactivated via 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 (once 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 for deactivating the measurement gap is detected or received). Furthermore, once 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 that deactivates the measurement gap (once the semi-persistent measurement gap is deactivated), terminal 200 can (until it detects or receives a DCI or MAC CE that activates the measurement gap) receive / transmit DL / UL channels / signals during each measurement gap opportunity without performing intra-frequency RRM measurement / inter-frequency RRM measurement. The aforementioned RRC parameters can be, for example, information elements that add parameters representing measurement gap types such as periodic measurement gaps, semi-persistent measurement gaps, and aperiodic measurement gaps to existing RRM measurement setting information elements (e.g., MeasGapConfig IE), or (new) information elements for semi-persistent measurement gaps that are identical 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 an RRC setting for an aperiodic measurement gap, and detects or receives an 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 example of the operation of terminal 200 related to the semi-continuous measurement gap.

[0281] In step S41, terminal 200 receives from base station 100 first information related to the extended period of 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 extended period for the measurement 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 may also be a DCI or MAC CE that describes the semi-persistent measurement gap and activates the measurement gap.

[0284] In step S44, during the extended period thereafter, the terminal 200 performs measurements 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 can perform signal reception or transmission without performing measurement during the extended period. For example, the third information could also be a DCI or MAC CE that describes a semi-persistent measurement gap and deactivates the measurement gap.

[0286] In addition, for periodic measurement gaps, steps S41 and S42 can be performed, and then steps S43 and S44 are not performed, but the periodic extended period is activated.

[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 effects of measurement-related scheduling constraints can be quietly mitigated by activating and deactivating semi-persistent measurement gaps and deactivating / non-periodic measurement gaps.

[0290] <Proposal 5>

[0291] As Proposal 5, it clarifies the notification regarding base station support for skipping or deactivating RRM measurements.

[0292] The operation of terminal 200 related to skipping or deactivating RRM measurements can be based on notification 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 does not perform RRM measurement during the RRM measurement opportunity, and previous scheduling restrictions are not applied to the measured symbol or the symbols within the SMTC window. When RRM measurement is not accompanied by a measurement gap, terminal 200 can receive DL channels / signals in the measured SSB / CSI-RS symbols (within the SMTC window) 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 by RRC for each RRM measurement setting. The semi-static notification based on RRC or SIB can also be referred to as information indicating that a measurement will not be performed (during a period associated with the measurement). 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 given RRM measurement setting. In this case, the object RRM measurement setting index (or ID) can also be notified by DCI or MAC CE. Dynamic notification 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 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 described in Alternative 2-1 (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 notification (or, the HARQ-ACK corresponding to the PDSCH corresponding to the MAC CE used for notification). Terminal 200 can also determine the initial RRM measurement opportunity that is skipped based on the DCI / MAC CE in this way. The value of X can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0304] Furthermore, the value of N can be defined by the standard (e.g., N=1), set by RRC, or notified by the DCI / MAC CE used for the notification.

[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, and the scheduling constraints defined in the current standard apply during these non-skipped RRM measurement opportunities. During N consecutive RRM measurement opportunities, terminal 200 may not perform RRM measurements but instead receive / transmit DL / UL channels / signals.

[0306] Option 1-2-2

[0307] As described in Alternative 2-2 (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 X symbols / slots after the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK corresponding to the PDSCH corresponding to the MAC CE used for the notification). Terminal 200 can also determine the start of the skip window based on the DCI / MAC CE in this way. The value of X can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0309] Furthermore, the length of the skip window can be defined by the standard, set by RRC, or notified by the DCI / MAC CE notification used for the notification.

[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, and the scheduling constraints defined in the current standard apply to these non-skipped RRM measurement opportunities. On RRM measurement opportunities included in the skip window, terminal 200 may not perform RRM measurements but instead receive / transmit DL / UL channels / signals.

[0311] Options 1-2-3

[0312] As illustrated in Alternative 2-3 (Alt 2-3) of Proposal 2, DCI or MAC CE can also inform whether to skip or not skip each of N (N is 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 notified RRM measurement opportunities. A bit value of "0" can also represent "not skipped (not skipped)," a bit value of "1" can also represent "skipped (skipped)," and a bit value of "0" can also represent "skipped (skipped)." For RRM measurement opportunities notified as "skipped," terminal 200 may not perform RRM measurements in that RRM measurement opportunity and may not apply the scheduling restrictions defined in the current standard to receive / transmit 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 restrictions defined in the current standard to RRM measurement opportunities that are not skipped.

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

[0315] Furthermore, the value of N can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0316] Options 1-2-4

[0317] As described in Alternative 2-4 (Alt 2-4) of Proposal 2, the DCI or MAC CE can also notify the deactivation of the RRM measurement to be set until the terminal 200 receives another DCI or MAC CE to activate the RRM measurement. In other words, if a DCI or MAC CE is received to deactivate the RRM measurement, the terminal 200 can also maintain the deactivation (state) of the RRM measurement until another DCI or MAC CE is received to activate the RRM measurement. The other DCI or MAC CE to activate the RRM measurement can also be referred to as information indicating (in another) part of the 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 that RRM measurement will be deactivated, terminal 200 may also decide to deactivate RRM measurement starting from X symbols / slots after the final symbol / slot of the notifying DCI (or, the HARQ-ACK corresponding to the PDSCH corresponding to the notifying MAC CE). The value of X can be defined by the standard, set by RRC, or notified by the notifying DCI / MAC CE.

[0319] If RRM measurement is deactivated, and terminal 200 detects or receives an alternative DCI or MAC CE from base station 100 notifying the activation of RRM measurement, terminal 200 may also decide to activate RRM measurement starting from Y symbols / slots after the final symbol / slot of the alternative DCI (or, the HARQ-ACK corresponding to the PDSCH corresponding to the alternative MAC CE). The value of Y can be defined by the standard, set by RRC, or notified by the alternative DCI / MAC CE.

[0320] [Option 2]

[0321] Skipping or deactivating RRM measurements can also be (commonly) notified / set for multiple RRM measurement settings. 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 by 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 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.

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

[0325] Alternate a (Alt a): All configured RRM measurement settings

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

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

[0328] Alternative d (Alt d): RRM measurement with or without measurement gap.

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

[0330] Alternative f (Alt f): A list of RRM measurement settings to be set.

[0331] Alternate g (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 notification (e.g., DCI or MAC CE) can also notify of the skipping or deactivation of RRM measurements for multiple RRM measurement settings. Dynamic notification 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 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 2-2-1 / 2-2-2 / 2-2-3 / 2-2-4.

[0334] Option 2-2-1

[0335] As described in Alternative 2-1 (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 X symbols / slots after the final symbol / slot of the DCI used for notification (or, the HARQ-ACK corresponding to the PDSCH corresponding to the MAC CE used for notification). Terminal 200 can also determine the initial RRM measurement opportunity that is skipped based on the DCI / MAC CE in this way. The value of X can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0337] Furthermore, the value of N can be defined by the standard (e.g., N=1), set by RRC, or notified by the DCI / MAC CE used for the notification.

[0338] RRM measurement opportunities not included in N consecutive RRM measurement opportunities are not skipped. Terminal 200 needs to perform RRM measurements within the non-skipped RRM measurement opportunities. Scheduling restrictions defined in the current standard do not apply to the non-skipped RRM measurement opportunities. Within N consecutive RRM measurement opportunities, terminal 200 may receive / transmit DL / UL channels / signals without performing RRM measurements.

[0339] Option 2-2-2

[0340] As described in Alternative 2-2 (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 X symbols / slots after the final symbol / slot of the DCI used for the notification (or, the HARQ-ACK corresponding to the PDSCH corresponding to the MAC CE used for the notification). Terminal 200 can also determine the start of the skip window based on the DCI / MAC CE in this way. The value of X can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0342] Furthermore, the length of the skip window can be defined by the standard, set by RRC, or notified by the DCI / MAC CE notification used for the notification.

[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, and the scheduling constraints defined in the current standard apply to these non-skipped RRM measurement opportunities. On RRM measurement opportunities included in the skip window, terminal 200 may not perform RRM measurements but instead receive / transmit DL / UL channels / signals.

[0344] Option 2-2-3

[0345] As described in Alternative 2-3 (Alt 2-3) of Proposal 2, DCI or MAC CE can also inform whether to skip or not skip each of N (N is 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 RRM measurement opportunities notified. A bit value of "0" can also represent "not skipped (not skipped)," a bit value of "1" can also represent "skipped (skipped)," and a bit value of "0" can also represent "skipped (skipped)." For RRM measurement opportunities notified as "skipped," terminal 200 may not perform RRM measurements in that RRM measurement opportunity and may not apply the scheduling restrictions defined in the current standard to receive / transmit 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 restrictions defined in the current standard to 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 X symbols / slots after the final symbol / slot of the DCI used for notification (or, the HARQ-ACK corresponding to the PDSCH corresponding to the MAC CE used for notification). Terminal 200 can also determine the initial RRM measurement opportunity to be skipped based on the DCI / MAC CE in this way. The value of X can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for notification.

[0348] Furthermore, the value of N can be defined by the standard, set by RRC, or notified by the DCI / MAC CE used for the notification.

[0349] Option 2-2-4

[0350] As described in Alternative 2-4 (Alt 2-4) of Proposal 2, the DCI or MAC CE can also notify the deactivation of the RRM measurement to be set until the terminal 200 receives another DCI or MAC CE to activate the RRM measurement. In other words, if a DCI or MAC CE is received to deactivate the RRM measurement, the terminal 200 can also maintain the deactivation (state) of the RRM measurement until another DCI or MAC CE is received 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 that RRM measurement will be deactivated, terminal 200 may also decide to deactivate RRM measurement starting from X symbols / slots after the final symbol / slot of the notifying DCI (or, the HARQ-ACK corresponding to the PDSCH corresponding to the notifying MAC CE). The value of X can be defined by the standard, set by RRC, or notified by the notifying DCI / MAC CE.

[0352] If RRM measurement is deactivated, and terminal 200 detects or receives an alternative DCI or MAC CE from base station 100 notifying that RRM measurement will be activated, terminal 200 may also decide to activate RRM measurement starting from Y symbols / slots after the final symbol / slot of the alternative DCI (or, the HARQ-ACK corresponding to the PDSCH corresponding to the alternative MAC CE). The value of Y can be defined by the standard, set by RRC, or notified by the alternative DCI / MAC CE.

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

[0354] Alternate h (Alt h): All configured RRM measurement settings

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

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

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

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

[0359] Alternate m (Alt m): A list of RRM measurement settings to be set.

[0360] Alternate n (Alt n): RRM measurement settings for a specific purpose or RRM measurement settings with a specific priority value.

[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 The operation example of 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 the period for associating with measurements using measurement signals 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, it describes the reporting of requests / notifications for terminal support to skip or deactivate RRM measurements.

[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 be set by RRC or notified by scheduling DCI. The request / notification to skip or deactivate RRM measurements can also be referred to as information indicating (within a periodic period 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, and / or semi-persistent, and / or non-periodic, and / or triggered by events. In the case of such reports being triggered by events, the event could, for example, be an event indicating a condition where measurement is not required. For example, the event could be a measurement period in which the received quality of the measurement signal (SSB, etc.) is within a specific range a specific number of times within multiple consecutive measurement periods (SMTC windows, etc.), or a measurement period in which the received quality of the measurement signal is within a specific range continues continuously for a specific number of times.

[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. After terminal 200 reports this request to base station 100, terminal 200 may also monitor / receive a notification from base station 100 notifying it of skipping or deactivating RRM measurements (the notification is sent from base station 100). In Option 1, how to skip RRM measurements may also depend on a notification from base station 100. That is, base station 100 may 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 the above-mentioned Proposal 5. That is, as explained in Proposal 5 above, the operation of terminal 200 when skipping RRM measurements can also follow the notification from base station 100.

[0377] For example, such as Figure 16As shown, after sending the request to base station 100, terminal 200 receives a notification on how to skip RRM measurement. Then, based on the notification from base station 100, 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, as well as information related to the requested / prompted skip opportunity (skipped RRM measurement opportunity). In this case, terminal 200 also requests / prompts for the skipped RRM measurement gap opportunity.

[0380] Option 2 requires either a notification from base station 100 regarding how to skip RRM measurements, or a confirmation (allow, permit) request from base station 100 to skip or deactivate RRM measurements. In the former case, terminal 200 skips the RRM measurement opportunity based on the notification from base station 100; in the latter case, terminal 200 skips the RRM measurement opportunity as requested / prompted by terminal 200. For further details, please refer to... Figure 17 as well as Figure 18 And will be discussed later.

[0381] The content of a request based on 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 X symbols / slots after 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 be defined by the standard, set by RRC, or notified by the request.

[0384] Furthermore, the value of N can be defined by the standard (e.g., N=1), set by the 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 X symbols / slots after 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] Furthermore, the length of the skip window can be defined by the standard, set by RRC, or notified by the request.

[0389] • For option 2-c: for each of N (N is an integer greater than or equal to 1) consecutive RRM measurement opportunities, whether to skip or not, the associated skip mode.

[0390] The request can also include a bitmap in which each bit indicates whether to skip or not skip the corresponding RRM measurement opportunity out of N consecutive RRM measurement opportunities. A bit value of "0" can also represent "not skipped (not skipped)," a bit value of "1" can also represent "skipped (skipped)," and a bit value of "0" can also represent "skipped (skipped)."

[0391] The initial RRM measurement opportunity in N consecutive measurement gap opportunities can also be the initial RRM measurement opportunity X symbols / slots after 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 be defined by the standard, set by RRC, or notified by the request.

[0392] Furthermore, the value of N can be defined by the standard, set by the RRC, or notified by the request.

[0393] Option 2-d: Terminal 200 may also notify the deactivation (remaining in a deactivated state) of the RRM measurement to be set 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 another) part of the periodic period associated with the measurement) to perform the measurement, etc.

[0394] Terminal 200 may also decide to deactivate the RRM measurement opportunity starting from X symbols / slots after the request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the request). The value of X can be defined by the standard, set by the RRC, or notified by the DCI / MAC CE used for notification.

[0395] If RRM measurement is deactivated, and terminal 200 sends another request to activate RRM measurement, terminal 200 may also decide to activate RRM measurement opportunity starting from Y symbols / slots after the final symbol / slot of the other request (e.g., the PUCCH / PUSCH / MAC CE corresponding to the other request). The value of Y can be defined by the standard, set by RRC, or notified by the other request.

[0396] • Variations of options 2-a / 2-b / 2-c / 2-d

[0397] The content requested by terminal 200 can also be one or more of the following options 1 (Alt 1) to 3 (Alt 3).

[0398] Alternative 1 (Alt 1)

[0399] The content requested by terminal 200 can also be content for all RRM measurement settings / types.

[0400] Alternative 2 (Alt 2)

[0401] The content of the request based on terminal 200 can also be the content of more than one specific RRM measurement setting, and more than one RRM measurement setting as the object can also be included in the request.

[0402] Alternative 3 (Alt 3)

[0403] 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 a measurement gap, RRM measurement in FR1 or RRM measurement in FR2, etc.).

[0404] After terminal 200 reports a request to base station 100 to skip or deactivate RRM measurements (e.g., following the request in options 2-a / 2-b / 2-c / 2-d), the operation of terminal 200 can also follow the following options 2-1 / 2-2.

[0405] Option 2-1

[0406] 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).

[0407] The notification from base station 100 regarding how to skip RRM measurement can also follow the above-mentioned Proposal 5. That is, as explained in Proposal 5 above, the operation of terminal 200 when skipping RRM measurement opportunities can also follow the notification from base station 100.

[0408] For example, such as Figure 17 As shown, after sending the request to base station 100, terminal 200 receives a notification from base station 100 regarding how to skip RRM measurement. Then, based on the notification from base station 100, terminal 200 skips the RRM measurement opportunity.

[0409] Option 2-2

[0410] Terminal 200 may also monitor / receive confirmations from base station 100 of requests to skip or deactivate RRM measurements (the confirmation is sent from base station 100). If terminal 200 receives the confirmation (in the monitoring window), it can skip the RRM measurement opportunity as requested. On the other hand, if terminal 200 does not receive the confirmation (in the monitoring window), it cannot skip the RRM measurement opportunity as requested.

[0411] The monitoring window described above can also be configured as follows.

[0412] • The monitoring window can start either as the first symbol / slot after the K symbols / slots of the request, or as the first symbol / slot monitored by the PDCCH after the request (for a specific search space type or a specific DCI format).

[0413] • The length of the monitoring window can be defined by the standard, set by RRC, or reported in the request.

[0414] 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).

[0415] As a variation of option 2-2, if the request based on terminal 200 is for multiple RRM measurement settings / types, the confirmation of base station 100 may also follow the following alternative 1 (Alt 1) / 2.

[0416] Alternative 1 (Alt 1): A single confirmation can be applied only to requests for multiple RRM measurement settings / types.

[0417] Alternative 2 (Alt 2): Terminal 200 can also assume (receive) confirmation according to each RRM measurement setting / type.

[0418] [Option 3]

[0419] Terminal 200 may also report to base station 100 a notification to skip or deactivate RRM measurement opportunities. In option 3, without notification from base station 100 on how to skip RRM measurement, or confirmation from base station 100 of a request to confirm (allow, authorize) skipping or deactivating RRM measurement, terminal 200 may skip RRM measurement opportunities as notified by terminal 200.

[0420] The content of the notification based on 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 rewritten as "notification".

[0421] The operation of terminal 200 after reporting a notification to base station 100 to skip or deactivate RRM measurement (e.g., following the notification of options 2-a / 2-b / 2-c / 2-d of proposal 6 above) can also be as follows.

[0422] • For RRM measurement opportunities that are notified as "skipped / deactivated", terminal 200 does not perform RRM measurements during those RRM measurement opportunities, and the scheduling restrictions defined in the current standard are not applied to the measured symbols or symbols within the SMTC window. When RRM measurements are not accompanied by measurement gaps, terminal 200 can receive DL channels / signals either in the measured SSB / CSI-RS symbols (within the SMTC window) or in all symbols within the SMTC window.

[0423] • For RRM measurement opportunities that are notified to be “not skipped / activated”, terminal 200 needs to perform RRM measurement in that RRM measurement opportunity. In RRM measurement opportunities that are not skipped, the scheduling constraints defined in the current standard are applied.

[0424] For example, such as Figure 19As shown, after sending the notification to the base station 100, the terminal 200 does not receive the notification and acknowledgment from the base station 100, and skips the RRM measurement opportunity as notified (e.g., based on the notified skip mode).

[0425] [Variations of options 1 / 2 / 3]

[0426] In the presence of multiple RRM measurement settings / types, terminal 200 may report a request / instruction to base station 100 without including details related to the RRM measurement setting / type to which the request / notification for skipping or deactivating RRM measurement is intended (either reporting a request / notification for skipping or deactivating RRM measurement to base station 100 for all of the multiple RRM measurement settings / types), or it may also report information related to the RRM measurement setting intended to be skipped or deactivated or a specific 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 a measurement gap, RRM measurement in FR1 or RRM measurement in FR2, etc.) to base station 100.

[0427] 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.

[0428] <Operation example>

[0429] Next, refer to Figure 25 The operation example of terminal 200 is explained.

[0430] 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.

[0431] In step S62, the terminal 200 periodically sets a period for associating with measurements using measurement signals based on the received first information.

[0432] In step S63, terminal 200 sends a second message indicating that no measurement will be performed to base station 100. For example, the second message may also be a request as described in option 1 / 2 or a notification as described in option 3.

[0433] In step S64, in response to the transmission of the second information in step S63, the terminal 200 does not perform measurement during one or another part of the periodic period, but performs signal reception or transmission with the base station.

[0434] Additionally, between steps S63 and S64, as described in option 1 / 2-1, base station 100 sometimes 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 sends an acknowledgment to terminal 200 that no measurement will be performed during a portion of the periodic period, as described in option 2-2, and sometimes no communication occurs between terminal 200 and base station 100, as described in option 3.

[0435] According to Proposal 6, it is possible to skip or deactivate RRM measurements (opportunities) based on requests / notifications from the terminal, thus reducing the impact of scheduling constraints related to measurements.

[0436] <UE capability>

[0437] The UE capability, which represents the capabilities of the terminal, may include information indicating the capabilities of the terminal as described below. Terminal 200 may also report this information, representing the capabilities of the terminal as described below, to base station 100. Furthermore, the information indicating the terminal's capabilities may be equivalent to the information defining the terminal's capabilities.

[0438] • Define whether the terminal supports transmitting / receiving information on the channel / signal prior to RRM measurements based on more than one specific condition.

[0439] • Define whether the terminal supports base station-based notifications to skip or deactivate measurement gap information.

[0440] • Define whether the terminal supports (in PUCCH / PUSCH / MAC CE) (periodic / semi-persistent / non-periodic / event-triggered) reporting of requests / notifications for skipping or deactivating measurement gaps.

[0441] • Define whether the terminal supports periodic / semi-continuous / periodic measurement gaps.

[0442] • Define whether the terminal supports base station-based notifications, skipping, or deactivation information.

[0443] • Define whether the terminal supports (in PUCCH / PUSCH / MAC CE) (periodic / semi-persistent / aperiodic / event-triggered) reporting of requests / notifications to skip or deactivate RRM measurements.

[0444] • Define the minimum processing time for notifications / acknowledgments to handle skipping or deactivation of measurement gap opportunities / RRM measurement opportunities (e.g., "X" in X symbols / slots, "K" in K symbols / slots, etc. above).

[0445] Furthermore, the above description illustrates an example of communicating between base station 100 and terminal 200 regarding skipping or deactivating measurement gaps (opportunities) and RRM measurements (opportunities), as well as notifications and requests (skip mode, etc.). However, it is also possible to communicate without skipping or activating measurement gaps (opportunities) and RRM measurements (opportunities), as well as notifications and requests (skip mode, etc.).

[0446] 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 function distinction and / or name of the functional unit are not limited if the function performs the operations involved in this embodiment.

[0447] <Base station structure>

[0448] Figure 26 This is a block diagram illustrating an example of the structure of the base station 10 according to this embodiment. The base station 10 includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. The base station 100 can also wirelessly communicate with the terminal 200 (see reference 100). Figure 27 ) to communicate.

[0449] The transmitting unit 101 sends downlink (DL) signals to the terminal 20. For example, the transmitting unit 101 sends DL signals (e.g., RRC, SIB, MAC CE, DCI, notification, acknowledgment, etc.) under the control of the control unit 103.

[0450] 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.

[0451] 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 to terminal 200, and uses the PDSCH to transmit downlink data signals.

[0452] 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.

[0453] 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.) under the control of the control unit 103.

[0454] The transmitting unit 101 and the receiving unit 102 can also be collectively referred to as a communication unit.

[0455] 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.

[0456] For example, the control unit 103 acquires data and control information from higher layers and outputs it to the transmitting unit 101. Furthermore, the control unit 103 outputs data and control information received from the receiving unit 102 to higher layers.

[0457] For example, the control unit 103 allocates resources (or channels) used for transmitting and receiving 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 sent to the terminal 200.

[0458] <Terminal Structure>

[0459] 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.

[0460] In connection with Proposal 1, for example, if the timing of receiving the signal overlaps with the period during which a measurement using a measurement signal (SSB measurement, etc.) overlaps (measurement gap opportunity, SMTC window, etc.), the receiving unit 201 may also receive the signal from the base station 100 at the aforementioned timing based on the determination of the control unit 203.

[0461] Related to Proposal 2, for example, receiving unit 201 may also receive from base station 100 first information (RRC, etc.) related to an 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, after receiving the second information from base station 100, receiving unit 201 may also receive information (MACCE, DCI, etc.) indicating that measurements are performed during another portion of the periodically extended period. Receiving unit 201 may also receive signals from base station 100 during a portion of the periodically extended period.

[0462] Related to Proposal 3, 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, after second information (request, etc.) is sent to base station 100, receiving unit 201 may also receive from 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 after the second information is sent to base station 100, receiving unit 201 may also receive from 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. After the second information is sent to base station 100, receiving unit 201 may also receive from base station 100 a 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. After the second information is sent to base station 100, receiving unit 201 may also receive from base station 100 a fifth information (confirmation, etc.) confirming that no measurement will be performed during a portion of the periodically extended period. For example, receiving unit 201 may also receive a signal from 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, and receiving unit 201 may also receive a signal from base station 100 during a portion of the periodically extended period based on the second information.

[0463] Related to 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.) for measurements using measurement signals (SSB, etc.) (SSB measurement, etc.). For example, receiving unit 201 may also receive from base station 100 second information (MAC CE, DCI, etc.) indicating activation of the extended period. For example, receiving unit 201 may also, based on the second information, not receive signals from base station 100 during periodically extended periods. For example, receiving unit 201 may also receive from base station 100 third information (MAC CE, DCI, etc.) indicating deactivation of the extended period. For example, receiving unit 201 may also, based on the third information, receive signals from base station 100 during periodically extended periods. For example, receiving unit 201 may also receive from base station 100 fourth information (MAC CE, DCI, etc.) indicating activation of the extended period. For example, receiving unit 201 may also, based on the fourth information, receive signals from base station 100 during an extended period.

[0464] Related to 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, after receiving the second information from base station 100, receiving unit 201 may also receive 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.

[0465] In connection with 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, after second information (request, etc.) is sent to base station 100, receiving unit 201 may also receive from 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 after the second information is sent to base station 100, receiving unit 201 may also receive from 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. After the second information is sent to base station 100, receiving unit 201 may also receive from base station 100 a 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. After the second information is sent to base station 100, receiving unit 201 may also receive from base station 100 a fifth information (confirmation, etc.) confirming that no measurement will be performed during a portion of the periodic period. For example, receiving unit 201 may also receive signals from 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, and receiving unit 201 may also receive signals from base station 100 during a portion of the periodic period based on the second information.

[0466] The transmitting unit 202 transmits the UL signal to the base station 100. For example, the transmitting unit 202 transmits the UL signal (e.g., the aforementioned request, notification, etc.) under the control of the control unit 203.

[0467] In connection with Proposal 1, for example, if the timing of transmitting the signal overlaps with the period during which a measurement (SSB measurement, etc.) using a measurement signal (SSB, etc.) overlaps (measurement gap opportunity, SMTC window, etc.), the transmitting unit 202 may also transmit the signal to the base station 100 at the aforementioned timing based on the determination of the control unit 203.

[0468] In connection with Proposal 2, for example, the transmitting unit 202 may also transmit the signal to the base station 100 during a portion of the periodic extension of the periodic extension of the measurement (SSB measurement, etc.) for which the measurement signal (SSB, etc.) is used.

[0469] Related to 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 extended period (measurement gap opportunity, etc.) for the measurement based on third, fourth, second, and fifth information. The second information may also indicate that a measurement will not be performed during a portion of the extended period, and the transmitting unit 202 may also not transmit a signal to the base station 100 during a portion of the extended period based on the second information.

[0470] Related to Proposal 4, for example, the transmitting unit 202 may also transmit a signal to the base station 100 during a periodically extended period (such as a measurement gap opportunity) for measurements using measurement signals (SSB, etc.) (SSB measurement, etc.) based on the second information. For example, the transmitting unit 202 may also transmit a signal to the base station 100 during a periodically extended period based on the third information. For example, the transmitting unit 202 may also not transmit a signal to the base station 100 during an extended period based on the fourth information.

[0471] In connection with Proposal 5, for example, the transmitting unit 202 may also transmit the 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.).

[0472] Related to 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 the 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.

[0473] The UL signal may also include, for example, uplink data signals and control information (e.g., UCI). It may also include information related to the processing capabilities of the terminal 200 (e.g., UE capability). Furthermore, the UL signal may also include reference signals.

[0474] The channels used in transmitting UL signals include, for example, uplink data channels and uplink control channels. For instance, the uplink data channel includes PUSCH (Physical Uplink Shared Channel), and the uplink control channel includes PUCCH (Physical Uplink Control Channel). For example, terminal 200 uses PUCCH to transmit uplink control information and uses PUSCH to transmit uplink data signals to base station 100.

[0475] The reference signals included in the UL signal may include, for example, at least one of DMRS, PTRS, CSI-RS, SRS, and PRS. For example, reference signals such as DMRS and PTRS are used for demodulation of uplink data signals and are transmitted using an uplink channel (e.g., PUSCH).

[0476] The receiving unit 201 and the transmitting unit 202 can also be collectively referred to as the communication unit.

[0477] The control unit 203 controls the communication operation of the terminal 200, which includes the receiving processing in the receiving unit 201 and the sending processing in the sending unit 202.

[0478] For example, control unit 203 acquires 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.

[0479] 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), or Scheduling Request (SR). The information fed back to base station 100 may also be included in UCI.

[0480] Related to Proposal 1, for example, when the timing of receiving or transmitting a signal overlaps with the period (measurement gap opportunity, SMTC window, etc.) associated with a measurement using a measurement signal (SSB, etc.), the control unit 203 can also determine whether to receive or transmit a signal or to perform a measurement using a measurement signal. For example, the control unit 203 can also make the above determination based on priority information indicating the signal and period and / or measurement, predefined conditions, etc. For example, the control unit 203 can also make the above determination when receiving or transmitting a signal in a specific cell (Pcell, etc.) or carrier (CC, etc.).

[0481] Related to Proposal 2, for example, the control unit 203 may also periodically set an extended period (measurement gap opportunity, etc.) for measurements using a measurement signal (SSB, etc.) based on the first information. For example, the control unit 203 may also determine, based on the second information, a portion of the periodically extended period during which the measurement will not be performed, and may also refrain from performing the measurement during the determined portion of the periodically extended period.

[0482] Related to Proposal 3, for example, the control unit 203 may also periodically set an extended period (measurement gap opportunity, etc.) for measurements using a measurement signal (SSB, etc.) (SSB measurement, etc.) based on the first information. For example, the control unit 203 may also determine a portion of the periodically extended period during which the measurement is not performed based on the second, third, fourth, and fifth information, and may also refrain from performing the measurement during the determined portion of the periodically extended period.

[0483] Related to Proposal 4, 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 activate the periodically extended period based on the second information. For example, the control unit 203 may also deactivate the periodically extended period based on the third information. For example, the control unit 203 may also activate the extended period based on the fourth information.

[0484] Related to 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 information, and may also refrain from performing measurements during the determined periodic period.

[0485] Related to Proposal 6, 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.

[0486] 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).

[0487] The above structure can reduce the impact of scheduling constraints related to measurement.

[0488] <Summary of Implementation Methods>

[0489] As explained above, in connection with Proposal 1, according to one aspect of this disclosure, a terminal is provided, comprising: a control unit that determines, when the timing of receiving or transmitting a signal overlaps with a period associated with a measurement using a measurement signal, whether to receive or transmit the signal or to perform a measurement using the measurement signal; and a communication unit that receives or transmits the signal at the timing based on the determination.

[0490] Based on the above structure, signal reception or transmission can be prioritized over measurement, thus reducing the impact of scheduling constraints related to measurement.

[0491] In one example, the control unit determines, based on information indicating the priority of the signal and the period and / or the measurement, whether to receive or send the signal, or to perform a measurement using the measurement signal.

[0492] Based on 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.

[0493] 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.

[0494] Based on the above structure, no signal exchange occurs between the terminal and the base station, thus reducing signaling overhead.

[0495] In one instance, the signal is received or transmitted within a specific cell.

[0496] Based on the above structure, by limiting the signal to be measured to a specific cell, it is possible to reduce signaling overhead and perform measurements more appropriately according to the cell.

[0497] In one example, the signal is received or transmitted on a specific carrier wave.

[0498] Based on the above structure, by limiting the signal to a specific carrier, it is possible to perform measurements more appropriately based on the carrier while reducing signaling overhead.

[0499] According to one aspect of this disclosure, a communication method is provided, wherein a terminal determines, when the timing of receiving or transmitting a signal overlaps with a period associated with a measurement using a measurement signal, whether to receive or transmit the signal or to perform a measurement using the measurement signal, and receives or transmits the signal at the determined timing.

[0500] Based on the above structure, signal reception or transmission can be prioritized over measurement, thus reducing the impact of scheduling constraints related to measurement.

[0501] Furthermore, in connection with 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 a measurement using the measurement signal, wherein the communication unit receives from the base station second information indicating that the measurement will not be 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.

[0502] Based on 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 mitigating the effects caused by measurement-related scheduling constraints.

[0503] In one example, a portion of the periodic extended period is N consecutive extended periods (N: an integer greater than 1).

[0504] Based on the above structure, it is possible to avoid performing measurements during periods when they are not suitable or when measurements are unnecessary.

[0505] In one example, a portion of the periodically extended period is the extended period included in the measurement non-execution period.

[0506] Based on the above structure, it is possible to avoid performing measurements during periods when they are not suitable or when measurements are unnecessary.

[0507] In one example, the second information includes third information indicating whether the measurement is performed or not in each of the consecutive extended periods, and a portion of the periodic extended periods is an extended period in the consecutive extended periods corresponding to the extended information indicating that the measurement is not performed.

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).

[0591] 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.

[0605] 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.

In addition, at least one of the base station and the mobile station also includes a device that is not necessarily mobile during communication operations. For example, at least one of the base station and the mobile station can also be an Internet of Things (IoT) device such as a sensor.

[0612] 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"). For example, uplink channel, downlink channel, etc., can also be rewritten as side channel.

[0613] Similarly, the terminal in this disclosure can also be rewritten as a base station. In this case, it can also be configured such that the base station has the functions of the terminal described above.

[0619] 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.

[0620] 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.

[0621] The communication module 2013 can communicate with the microprocessor 2031 and the constituent elements of the vehicle 2001 via a communication port.

[0622] 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. The communication module 2013 can be located either inside or outside the electronic control unit 2010. External devices can be, for example, base stations, mobile stations, etc.

[0626] <Meaning and Explanation of Terms>

[0627] The terms "determining" and "determining" as used in this disclosure encompass a wide variety of actions. For example, "determining" and "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" and "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" and "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.

[0628] 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.

[0629] <Reference Signal>

[0630] 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.

[0631] <The meaning of "based on">

[0632] 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".

[0633] <"First", "Second">

[0634] 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.

[0635] <Unit>

[0636] Alternatively, the term "unit" in the structure of the above devices can be replaced with "section", "circuit", "equipment", etc.

[0637] <Open format>

[0638] 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.

[0639] <Time units such as TTI, frequency units such as RB, and radio frame structure>

[0640] 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).

[0641] 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.

[0642] 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.

[0643] A time slot can also comprise 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.

[0644] 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.

[0645] 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.

[0646] 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.

[0647] 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.

[0648] 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.

[0649] 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.

[0650] 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.

[0651] A resource block (RB) is a unit of resource allocation in both the time and frequency domains. In the frequency domain, it can also include one or more consecutive subcarriers. The number of subcarriers included in an RB can be the same regardless of the parameter set, for example, it can be 12. The number of subcarriers included in an RB can also be determined based on the parameter set.

[0652] Furthermore, the time domain of an RB can also include 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.

[0653] 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.

[0654] 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.

[0655] 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.

[0656] 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.

[0657] 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."

[0658] 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 included in a radio frame, the number of time slots in each subframe or radio frame, the number of mini-time slots included in a time slot, the number of symbols and RBs included in a time slot or mini-time slot, the number of subcarriers included in an RB, and the number of symbols in a TTI, symbol length, and cyclic prefix (CP) length can be varied in many ways.

[0659] <Maximum Transmit Power>

[0660] 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).

[0661] <Article>

[0662] 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.

[0663] <"Differences">

[0664] 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."
