Terminal and communication method

Abstract

This terminal is provided with: a control unit that, when the timing of reception or transmission of a signal overlaps with a period associated with measurement using a measurement signal, determines, on the basis of skip information received from a network, which one is to be skipped between the reception or transmission of the signal and the measurement using the measurement signal; and a communication unit that, if the reception or transmission of the signal is prioritized, performs the reception or transmission of the signal at the timing.

Description

Terminal and communication method

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

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

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

[0004] The expansion of mobile communication systems as described above is expected to lead to the use and spread of extended reality (XR), such as virtual reality (VR), augmented reality (AR), and mixed reality (MR), which enable the combination of the real world and the virtual world (virtual content). 3GPP is currently discussing XR expansion in preparation for Release 19 (see, for example, Non-Patent Document 2).

[0005] In the context of XR extensions, for example, extensions regarding Measurement Gap (MG) and scheduling restrictions have been widely discussed.

[0006] For example, it may be within the scope of future standards to specify extensions to the scheduling restrictions for inter-frequency RRM measurements in FR1 and FR2 with measurement gaps and intra-frequency RRM measurements in FR2 without measurement gaps to reduce the impact on capacity and on individual terminals.

[0007] 3GPP TS 38.300 V17.6.0 (2023-09)“New WID: XR (eXtended Reality) for NR Phase 3”, RP-234080, 3GPP TSG-RAN Meeting #103, December 11-15, 2023

[0008] Current wireless communication systems utilize measurements using synchronization signal blocks (SSBs) (SSB-based measurements (sometimes referred to as "SSB measurements")).

[0009] For SSB-based measurements, a measurement timing configuration (SMTC) is notified to a terminal, and the terminal performs measurements based on signals to be measured in the configured SMTC window. Furthermore, for SSB-based measurements, a measurement gap configuration can be notified to the terminal for switching the used frequency (RF: Radio Frequency), etc.

[0010] Due to the periodicity of XR traffic, if the SMTC window or measurement gap overlaps with the transmission and reception of signals related to XR traffic, the signals cannot be scheduled, which can lead to problems due to scheduling restrictions associated with measurements, such as capacity loss.

[0011] In addition, current wireless communication systems also use other measurements such as measurements using a Channel State Information Reference Signal (CSI-RS) (CSI-RS based measurements (sometimes referred to as "CSI-RS measurements")), and the above-mentioned problems may also occur in various measurements. Furthermore, the above-mentioned problems may also occur in transmission and reception of signals other than signals related to XR traffic.

[0012] One aspect of the present disclosure provides a terminal and a communication method that can reduce the impact caused by scheduling restrictions on measurements.

[0013] A terminal according to one aspect of the present disclosure includes a control unit that, when the timing of receiving or transmitting a signal overlaps with a period associated with measurement using a measurement signal, determines whether to skip reception or transmission of the signal or measurement using the measurement signal based on skip information received from a network, and a communication unit that receives or transmits the signal at the timing when priority is given to reception or transmission of the signal.

[0015] Hereinafter, an embodiment according to one aspect of the present disclosure will be described with reference to the drawings.

[0016] 1 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 wireless communication system conforming to 5G NR, and includes a Next Generation-Radio Access Network 20 (hereinafter, NG-RAN 20) and a terminal (hereinafter, also referred to as UE (User Equipment) 200).

[0017] The wireless communication system 10 may be a wireless communication system conforming to a system called Beyond 5G, 5G Evolution, or 6G.

[0018] The NG-RAN 20 includes a base station A (hereinafter also referred to as gNB 100A) and a base station B (hereinafter also referred to as gNB 100B). When it is not necessary to distinguish between the gNB 100A, the gNB 100B, etc., they are collectively referred to as gNBs or base stations. Furthermore, the number of gNBs and UEs is not limited to the example shown in FIG. 1.

[0019] The NG-RAN 20 actually includes multiple NG-RAN nodes, specifically, gNBs (or ng-eNBs), and is connected to a 5G-compliant core network (5GC, not shown). The NG-RAN 20 and 5GC may simply be referred to as "networks." In the following, the term "gNB" may be replaced with "network (NW)."

[0020] As an example, the gNB 100A and the gNB 100B are base stations conforming to 5G, and perform 5G wireless communication with the UE 200. The gNB 100A, the gNB 100B, and the UE 200 may support MIMO (Multiple-Input Multiple-Output), which generates a more directional beam BM by controlling radio signals transmitted from multiple antenna elements, carrier aggregation (CA), which uses a bundle of multiple component carriers (CC), and dual connectivity (DC), which performs communication between the UE and each of two NG-RAN nodes.

[0021] The wireless communication system 10 may also support multiple frequency ranges (FR). Fig. 2 is a diagram showing an example of FRs used in the wireless communication system 10. As shown in Fig. 2, the wireless communication system 10 may support FR1 and FR2. The frequency bands of each FR are, for example, as follows: FR1: 410 MHz to 7.125 GHz FR2: 24.25 GHz to 52.6 GHz

[0022] FR1 may use a sub-carrier spacing (SCS) of 15 kHz, 30 kHz, or 60 kHz, and a bandwidth (BW) of 5 to 100 MHz. FR2 is a higher frequency than FR1, and may use an SCS of 60 kHz or 120 kHz (including 240 kHz), and a bandwidth (BW) of 50 to 400 MHz.

[0023] Note that SCS may be interpreted as numerology, which is defined in 3GPP TS 38.300 and corresponds to one subcarrier spacing in the frequency domain.

[0024] Furthermore, the wireless communication system 10 may support a frequency band higher than the FR2 frequency band. Specifically, the wireless communication system 10 may support a frequency band exceeding 52.6 GHz up to 114.25 GHz. For convenience, such a high frequency band may be referred to as "FR2x." When using a frequency band exceeding 52.6 GHz, CP-OFDM (Cyclic Prefix-Orthogonal Frequency Division Multiplexing) / DFT-S-OFDM (Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing) with a larger SCS may be applied.

[0025] 3 is a diagram showing an example of the configuration of a radio frame (system frame), subframe, and slot used in the radio communication system 10. As shown in FIG. 3, one slot is composed of 14 symbols, and the larger (wider) the SCS, the shorter the symbol period (and slot period). However, the SCS is not limited to the interval (frequency) shown in FIG. 3. For example, 480 kHz, 960 kHz, etc. may be used as the SCS.

[0026] Furthermore, the number of symbols constituting one slot does not necessarily have to be 14 (for example, it may be 28 or 56 symbols, etc.) Furthermore, the number of slots per subframe may differ depending on the SCS.

[0027] 3 may be called a time domain, a symbol period, a symbol time, etc. The frequency direction may be called a frequency domain, a resource block, a subcarrier, a bandwidth part (BWP), etc.

[0028] The gNB100 transmits control information, setting information, etc. to the UE200 as a downlink (DL) signal.

[0029] Furthermore, for example, gNB100 receives control information, data signals, information regarding the processing capabilities of UE200 (terminal capabilities (information); for example, UE capability), etc. from UE200 as uplink (UL) signals.

[0030] Channels used for transmitting DL signals include, for example, data channels and control channels. For example, the data channel may include a physical downlink shared channel (PDSCH), and the control channel may include a physical downlink control channel (PDCCH). For example, the gNB 100 transmits control information to the UE 200 using the PDCCH, and transmits DL data signals using the PDSCH. Note that the PDSCH is an example of a downlink shared channel, and the PDCCH is an example of a downlink control channel. Note that the PDCCH may be interpreted as downlink control information (DCI), control information, etc. transmitted in the PDCCH.

[0031] The reference signal included in the DL signal may include, for example, at least one of a DMRS (Demodulation Reference Signal), a PTRS (Phase Tracking Reference Signal), a CSI-RS (Channel State Information - Reference Signal), an SRS (Sounding Reference Signal), and a PRS (Positioning Reference Signal) for position information. For example, reference signals such as the DMRS and PTRS are used to demodulate the DL data signal and are transmitted using the PDSCH.

[0032] The UE 200 is a communication device equipped with a wireless communication function, such as a smartphone, a mobile phone, a tablet, a wearable terminal, or an M2M (Machine-to-Machine) communication module.

[0033] UE200 receives control signals or data signals from gNB100 in DL and transmits control signals or data signals to gNB100 in UL, thereby utilizing various communication services provided by wireless communication system 10. UE200 also receives various reference signals transmitted from gNB100 and performs measurement of propagation path quality based on the reception results of the reference signals.

[0034] For example, UE200 receives control information, configuration information, etc. from gNB100 as a DL signal.

[0035] Also, for example, UE200 transmits control information, data signals, terminal capability information of UE200, etc. to gNB100 as UL signals.

[0036] Channels used for transmitting UL signals include, for example, data channels and control channels. For example, the data channel may include a Physical Uplink Shared Channel (PUSCH), and the control channel may include a Physical Uplink Control Channel (PUCCH). For example, the UE 200 transmits control information using the PUCCH and transmits UL data signals using the PUSCH. Note that the PUSCH is an example of an uplink shared channel, and the PUCCH is an example of an uplink control channel. Note that the PUSCH or the PUCCH may be interpreted as uplink control information (UCI), control information, etc. transmitted in the PUSCH or the PUCCH.

[0037] The reference signal included in the UL signal may include, for example, at least one of a DMRS, a PTRS, a CSI-RS, an SRSRS, and a PRS for location information. For example, the reference signal such as the DMRS or the PTRS is used for demodulating the UL data signal and is transmitted using the PUSCH.

[0038] <Current status of discussions on XR> XR presents attractive use cases for future wireless communication systems. However, XR also poses challenges that need to be considered and addressed. For example, in 3GPP, XR extensions are being discussed for Release 19 (see, for example, Non-Patent Document 2), and extensions related to measurement gaps and scheduling restrictions are being widely discussed.

[0039] Regarding SSB and SSB-based measurements, some signals and / or channels transmitted from a base station to a terminal are periodically transmitted. Examples of such signals and / or channels include synchronization signal blocks (SSBs).

[0040] The SSB is used by the terminal to measure (SSB-based measurement) 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.

[0041] For SSB-based measurements, a measurement timing configuration (SMTC) is notified to the terminal. The SMTC may include the length, period, timing offset, etc. of the SSB-based measurement period (which may also be called an SMTC window, measurement timing, etc.). The terminal performs measurements based on the signal to be measured within the configured SMTC window.

[0042] Furthermore, for SSB-based measurements, measurement gap settings may be notified to the terminal due to switching of the used frequency (RF: Radio Frequency). A measurement gap is an extended period for measurements, in which additional periods may be added before and after the SMTC window. The measurement gap settings may also include a length, a period, etc.

[0043] Examples of RRM measurements also include CSI-RS based measurements.

[0044] In NR, the following RRM measurements are used, including SSB-based measurements and CSI-RS-based measurements, with or without measurement gaps: (1) Intra-frequency measurements (2) Inter-frequency measurements (3) Inter-frequency measurements (4)

[0045] The terminal can perform the above-mentioned RRM measurements and transmit / receive signals using at least one frequency band (carrier frequency) of the first frequency band (FR1) and the second frequency band (FR2).

[0046] <Regarding PRS Measurement Priority> In the case of DL PRS (Positioning Reference Signal) measurement, a DL PRS priority is introduced to determine the priority between the DL PRS and other DL channels / signals.

[0047] The terminal determines the priority between the DL PRS and the DL signals and channels as follows, either explicitly by the priority of higher layer parameters according to the terminal capabilities or implicitly by the terminal capabilities excluding SSB: - If the priority value of the DL PRS is "st1", the DL PRS has higher priority than all DL signals and channels; - If the priority value of the DL PRS is "st2", the DL PRS has lower priority than the PDCCH, higher priority than the PDSCH scheduled by a DCI format whose priority indicator field is set to "1" (e.g., DCI1_1, DCI1_2, DCI1_3), and higher priority than other DL signals and channels; - If the priority value of the DL PRS is "st3", the DL PRS has lower priority than all DL signals and channels.

[0048] <Scheduling Restrictions for RRM Measurements> Scheduling restrictions (terminal operation restrictions) for intra-frequency SSB-based measurements without measurement gaps, with NCSG (Network Configured Small Gap), and with measurement gaps are described in the current standard in the following places: Intra-frequency SSB-based measurements without measurement gaps: TS 38.133 clause 9.2.5.3 (in brief, scheduling restrictions are imposed on SSB symbols measured within an SMTC window or on all symbols within an SMTC window, if the conditions are met) Intra-frequency SSB-based measurements with NCSG: TS 38.133 clause 9.2.5.3 Intra-frequency SSB-based measurements with measurement gaps: TS 38.133 clause 9.1.2

[0049] Regarding inter-frequency SSB-based measurements, the scheduling restrictions (terminal operation restrictions) for inter-frequency SSB-based measurements without measurement gaps, inter-frequency SSB-based measurements with NCSG, and inter-frequency SSB-based measurements with measurement gaps are described in the following sections of the current standard: Inter-frequency SSB-based measurements without measurement gaps: TS 38.133 clause 9.3.5.3 (briefly, if the condition is met, a scheduling restriction is imposed on the SSB symbols measured within the SMTC window or on all symbols within the SMTC window) Inter-frequency SSB-based measurements with NCSG: TS 38.133 clause 9.2.10.3 (briefly, if the condition is met, a scheduling restriction is imposed on the union of the SSB symbols measured within the SMTC window for all Measurement Occasions (MOs) or on the union of all symbols within the SMTC window for all MOs) Inter-frequency SSB-based measurements with measurement gaps: TS 38.133 clause 9.1.2

[0050] Regarding intra-frequency CSI-RS-based measurements, the scheduling restrictions (terminal operation restrictions) for intra-frequency CSI-RS-based measurements without measurement gaps are described in the current standard in the following places: Intra-frequency CSI-RS-based measurements without measurement gaps: TS 38.133 clause 9.10.2.6 (in brief, scheduling restrictions are imposed on configured CSI-RS symbols if the conditions are met).

[0051] Regarding inter-frequency CSI-RS based measurements, the scheduling restrictions (terminal operation restrictions) for inter-frequency CSI-RS based measurements with measurement gaps are described in the current standard in the following section: Inter-frequency CSI-RS based measurements with measurement gaps: TS 38.133 clause 9.1.2

[0052] Due to the periodicity of XR traffic, if the SMTC window or measurement gap overlaps with the transmission or reception of signals related to XR traffic, the signals cannot be scheduled, resulting in capacity loss and other problems due to scheduling restrictions associated with measurements.

[0053] In order to prioritize channel / signal transmission / reception in response to measurement gaps / scheduling restrictions caused by RRM measurements, there is a need to consider using semi-static notification via RRC (Radio Resource Control) or the like.

[0054] When using this semi-static notification, the details of the setting pattern for priority processing and the granularity of the settings have not been sufficiently considered.

[0055] Therefore, a specific proposal for setting priority processing using this semi-static notification will be described below.

[0056] More specifically, this proposal includes the following Proposal 1 to Proposal 3. Proposal 1: Setting / applying a "skip pattern" via RRC to prioritize channel / signal transmission / reception over measurement gaps / scheduling restrictions resulting from RRM measurements and to indicate opportunities to skip measurement gaps / scheduling restrictions. Proposal 2: When measurement gaps / scheduling restrictions resulting from RRM measurements collide with a specific semi-statically pre-configured channel / signal transmission / reception opportunity, setting an "RRM skip indicator" for the transmission / reception opportunity and skipping measurement gaps / scheduling restrictions based on the "RRM skip indicator." Proposal 3: Measurement gaps / scheduling restrictions resulting from RRM measurements skip measurement gaps / scheduling restrictions based on semi-statically pre-configured "priority information" for specific semi-statically pre-configured channel / signal transmission / reception and / or specific measurement gaps / scheduling restrictions.

[0057] In the following, Proposals 1 to 3 are described assuming that the measurement gap is periodic. For example, the measurement gap (configuration) may be configured by an existing measurement gap configuration information element (e.g., MeasGapConfig IE), which is an RRC parameter, or a (new) information element similar to the existing information element. The measurement gap period may be configured in such an information element.

[0058] The items explained in Proposals 1 to 3 may be combined as appropriate as long as no contradictions arise.

[0059] In this application, the notation " / " may mean "and / or" unless otherwise specified.

[0060] In addition, in this application, the expression "not receiving / transmitting" may be interpreted as "not assuming reception / transmission," "reception / transmission is disabled," "not performing reception / transmission," "restricting reception / transmission," "assuming reception / transmission is not possible," etc.

[0061] Furthermore, in this application, the expression "deactivate" may be interpreted as "disable", "turn off", "put into an inactive (or disabled) state (disabled state, off state)", etc., and "enable" may be interpreted as "enable", "turn on", "put into an active (or disabled) state (disabled state, off state)", etc.

[0062] In addition, in this application, the expression "notification" may be read as the expression "instruction."

[0063] In addition, in this application, signals such as SSB and CSI-RS used to measure received power, received quality, etc. may be referred to as measurement signals, measurement signals, etc.

[0064] In addition, in this application, "skipping or disabling" may be interpreted as "not performing measurements (e.g., RRM measurements) on" or "assuming that scheduling restrictions do not apply on" (do not assume that scheduling restrictions apply), etc.

[0065] In addition, in this application, "transmission / reception of a channel / signal (by a terminal)" may be abbreviated to "channel / signal".

[0066] <Proposal 1> In the following, we will describe configuring / applying a "skip pattern" via RRC to prioritize channel / signal transmission / reception over measurement gaps / scheduling restrictions resulting from RRM measurements and to indicate opportunities to skip measurement gaps / scheduling restrictions (Proposal 1). The process of prioritizing channel / signal transmission / reception over measurement gaps / scheduling restrictions and skipping measurement gaps / scheduling restrictions may be called priority processing, etc.

[0067] Support for notification by base stations to skip or disable measurement gaps is described.

[0068] The terminal's behavior regarding skipping or disabling measurement gaps may be based on notification by the base station.

[0069] For example, if the terminal is notified by the base station to skip or disable a measurement gap occasion, the terminal may not perform RRM measurements (and / or Positioning Reference Signal (PRS) measurements) during the measurement gap occasion, and may receive / transmit DL / UL channels / signals during the measurement gap occasion.

[0070] The skipping or disabling of a measurement gap opportunity may be signaled according to the following procedure.

[0071] The skipping or disabling of measurement gap occasions may be notified by semi-static notification via RRC or SIB. For example, RRC may configure a skipping pattern, or the SIB may notify the skipping pattern. When multiple measurement gap configurations are configured, the skipping pattern may be common to all of the multiple measurement gap configurations, or may be configured / notified for each measurement gap configuration. The semi-static notification via RRC or SIB may be referred to as information indicating that measurements will not be performed (during part of the periodic extended period for measurements), or the like. The terminal may be notified of the skipping or disabling of measurement gap occasions by receiving the semi-static notification from the base station, and may determine which measurement gap occasions to skip and / or which measurement gap occasions not to skip based on the semi-static notification.

[0072] Measurement gap occasions configured / indicated as not skipped shall not be skipped, and the terminal shall perform RRM measurements in the non-skipped measurement gap occasions, during which the scheduling restrictions defined in the current standard shall apply. In measurement gap occasions configured / indicated as skipped, the terminal shall not perform RRM measurements and may receive / transmit DL / UL channels / signals.

[0073] 4 shows an example of notification of skipping of the measurement gap occasions described above. As shown in FIG. 4, when the skip pattern set for the measurement gap configuration is "Not skip / enable," "Skip / disable," "Not skip / enable," or "Not skip / enable," among the measurement gap occasions shown in the figure, the first measurement gap occasion is set as not skipped (enabled), the second measurement gap occasion is set as skipped (disabled), the third measurement gap occasion is set as not skipped (enabled), and the fourth measurement gap occasion is set as not skipped (enabled). Therefore, the terminal decides to skip the second measurement gap occasion, and the terminal may receive / transmit DL / UL channels / signals without performing RRM measurements in the second measurement gap.

[0074] Below, we will explain Proposal 1 in three cases: when the granularity of setting / applying the skip pattern is changed (Proposal 1-1); when the skip pattern is based on a bitmap (Proposal 1-2); and when the skip pattern is based on a time window (periodicity, offset, duration) (Proposal 1-3).

[0075] <Proposal 1-1> This section explains changing the granularity of setting / applying the skip pattern (Proposal 1-1). This skip pattern may be set / applied as follows: (1) The skip pattern may be set / applied to all configured measurement gap configurations / SMTC configurations / RRM measurement configurations (Option 1-1). (2) The skip pattern may be set / applied for each measurement gap configuration / SMTC configuration / RRM measurement configuration (Option 1-2). (3) The skip pattern may be set / applied for each configured subset of measurement gap configurations / SMTC configurations / RRM measurement configurations (Option 1-3).

[0076] Option 1-1 to Option 1-3 will be described in detail below.

[0077] [Option 1-1] The skip pattern may be set / applied to all the set measurement gap configurations / SMTC configurations / RRM measurement configurations.

[0078] For example, a skip pattern (configured by a bitmap, a periodic time window (periodicity, offset, duration), etc.) may be configured / applied (for all measurement gap configurations) by, for example, MeasConfig or MeasGapConfig.

[0079] [Option 1-2] A skip pattern may be set / applied for each measurement gap configuration / SMTC configuration / RRM measurement configuration.

[0080] For example, a skip pattern (configured by a bitmap, a periodic time window (periodicity, offset, duration), etc.) may be configured / applied (per measurement gap configuration) by GapConfig. Similarly, a skip pattern may be configured / applied (per SMTC configuration) by SSB-MTC or SSB-MTC2.

[0081] For example, one or more skip patterns (configured by bitmaps, periodic time windows (periodicity, offset, duration), etc.) may be configured by MeasConfig or MeasGapConfig, and corresponding measurement gap configurations / SMTC configurations / RRM measurement configurations may also be configured / applied for each skip pattern.

[0082] [Options 1-3] A skip pattern may be configured / applied for each configured subset of measurement gap configurations / SMTC configurations / RRM measurement configurations.

[0083] For example, one or more skip patterns (configured by bitmaps, periodic time windows (periodicity, offset, duration), etc.) may be configured / applied in MeasConfig or MeasGapConfig for a subset of measurement gap configurations.

[0084] A subset of the measurement gap configurations / SMTC configurations / RRM measurement configurations may be defined by a specification or configured / applied by the RRC, for example, a measurement gap configuration / SMTC configuration / RRM measurement configuration corresponding to each skip pattern may be configured / applied.

[0085] <Proposal 1-2> A case where the above skip pattern is based on a bitmap (Proposal 1-2) will be described. In this case, the (maximum) length of the bitmap can be defined by the specifications.

[0086] Each bit in the bitmap may be set / applied to be mapped to a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity.

[0087] For example, a bit in the bitmap may be mapped to either a corresponding measurement gap configuration / SMTC configuration / RRM measurement configuration, all configured measurement gap configurations / SMTC configurations / RRM measurement configurations, or a subset of the measurement gap configurations / SMTC configurations / RRM measurement configurations.

[0088] For the bitmap described above, the first bit of the bitmap may be set as follows:

[0089] [Option 1-a] The first bit of the bitmap may be mapped to the first opportunity of the (corresponding) measurement gap configuration / SMTC configuration / RRM measurement configuration after configuration / activation.

[0090] [Option 1-b] The first bit of the bitmap may be mapped to the first opportunity of the (corresponding) measurement gap configuration / SMTC configuration / RRM measurement configuration in frame 0.

[0091] Furthermore, subsequent bits in the bitmap may be mapped to subsequent opportunities for (corresponding) measurement gap configuration / SMTC configuration / RRM measurement configuration.

[0092] The bitmap may also be applied periodically.

[0093] If the corresponding bit in a measurement gap occasion / SMTC occasion / RRM measurement occasion is "0" (or "1"), the measurement gap occasion / SMTC occasion / RRM measurement occasion may be skipped.

[0094] As an example, via RRC, a bitmap may be signaled (or may include) in which each bit indicates whether a corresponding measurement gap opportunity among the signaled N consecutive measurement gap opportunities is skipped or not. A bit value of "0" may indicate "not skipped" and a bit value of "1" may indicate "skip." Alternatively, a bit value of "1" may indicate "not skipped" and a bit value of "0" may indicate "skip." For measurement gap opportunities signaled as "skipped," terminal 200 does not perform RRM measurements during the measurement gap opportunities, scheduling restrictions defined in the current standard do not apply, and terminal 200 may receive / transmit DL / UL channels / signals. On the other hand, for measurement gap opportunities signaled as "not skipped," terminal 200 must perform RRM measurements during the measurement gap opportunities, and scheduling restrictions defined in the current standard apply to non-skipped measurement gap opportunities.

[0095] The first measurement gap opportunity among the N consecutive measurement gap opportunities may be determined to be the first measurement gap opportunity X symbols / slots after the last symbol / slot of the RRC skip pattern for the notification. In this manner, terminal 200 may determine the first measurement gap opportunity to be skipped via RRC. The value of X may be defined by the standard, configured by RRC, or notified by the DCI / MAC CE for the notification.

[0096] Furthermore, the value of N may also be defined by a standard, may be set by the RRC, or may be notified by a DCI / MAC CE for notification.

[0097] 5 shows an example of notification of skipping of measurement gap opportunities, in which a skip pattern for N consecutive measurement gap opportunities (N=4 in the example shown in FIG. 5) is notified by bitmap via RRC. In this example, the bitmap (skip pattern) is "0100" (0: not skipped, 1: skipped in this example), and the second measurement gap opportunity shown in the figure is skipped. Therefore, terminal 200 decides to skip the second measurement gap opportunity shown in the figure, and may receive / transmit DL / UL channels / signals without performing RRM measurements during this measurement gap opportunity.

[0098] (Variation of Proposal 1-2) As a variation of Proposal 1-2, if the corresponding bit is "0" (or "1"), if there is a DL / UL channel / signal received / transmitted that overlaps with a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity, the measurement gap opportunity / SMTC opportunity / RRM measurement opportunity may be skipped.

[0099] <Proposal 1-3> A case where the skip pattern described above is based on a time window in which periodicity, offset, or duration is set (Proposal 1-3) will be described.

[0100] (Unit of Period / Offset / Period Setting) The configuration units of the periodicity, offset, and period of the time window may be set / applied as follows: Alt (Alternation).

[0101] (Alt. a) The configuration unit of the time window periodicity, offset, and duration may be set / applied on a frame / subframe basis.

[0102] (Alt. b) The configuration unit of the time window periodicity, offset and duration may be set / applied in slot / symbol units based on the reference SCS (SubCarrier Spacing).

[0103] In Alt. b, the reference SCS mentioned above may be determined as follows:

[0104] (Alt. b-1) The reference SCS may be configured by the RRC. For example, the reference SCS may be configured by the RRC together with the configuration of the skip pattern.

[0105] (Alt. b-2) The reference SCS may be set based on the cell of the measurement gap configuration / SMTC configuration / RRM measurement configuration.

[0106] If the skip time window is configured for all measurement gap configurations / SMTC configurations / RRM measurement configurations, the reference SCS may be the minimum / maximum SCS of all serving cells or the minimum / maximum SCS of cells of all configured measurement gap configurations / SMTC configurations / RRM measurement configurations.

[0107] If the skip time window is configured per SMTC configuration / RRM measurement configuration, the reference SCS may be the SCS of the serving cell in which the SMTC configuration / RRM measurement configuration is configured.

[0108] If the skip time window is configured for each measurement gap configuration, the reference SCS may be the minimum / maximum SCS of the cell corresponding to the measurement gap configuration. For example, if the measurement gap configuration is per UE, the reference SCS may be the minimum / maximum SCS of all serving cells. If the measurement gap configuration is FR1 / FR2, the reference SCS may be the minimum / maximum SCS of the FR1 / FR2 serving cell.

[0109] If the skip time window is configured for each configured subset of SMTC configuration / RRM measurement configuration, the reference SCS may be the SCS of the serving cell in which the subset of SMTC configuration / RRM measurement configuration is configured.

[0110] Determining Skip Time Window Based on Periodicity / Offset / Duration Settings The skip time window may be determined based on the periodicity, offset, and duration configurations.

[0111] The skip time window may be determined for each period, and each period may be determined according to a set periodicity. The start position of the skip time window for each period may be determined based on a relative offset from the start position of each period.

[0112] In this case, the start position of the first period may be the first subframe / slot / symbol of frame 0.

[0113] Based on the skip time window, measurement gap opportunities / SMTC opportunities / RRM measurement opportunities may be skipped.

[0114] If a measurement gap opportunity / SMTC opportunity / RRM measurement occasion overlaps with or is within a skip time window determined based on the periodicity, offset, and duration, the measurement gap opportunity / SMTC opportunity / RRM measurement occasion may be skipped. The terminal may receive DL channels / signals or transmit UL channels / signals during the measurement gap opportunity / SMTC opportunity / RRM measurement occasion.

[0115] (Effects of Proposal 1) The above proposal allows adaptive and granular prioritization of signal reception or transmission over measurements, thereby reducing the impact of scheduling restrictions on measurements under flexible conditions.

[0116] <Proposal 2> In the following, we will explain a proposal (Proposal 2) that, when a measurement gap / scheduling restriction resulting from RRM measurement collides with a transmission / reception opportunity for a specific quasi-statically pre-configured channel / signal, an "RRM skipping indicator" is set for the transmission / reception opportunity, and the measurement gap / scheduling restriction is skipped based on the "RRM skipping indicator."

[0117] The priority of channels / signals for measurement gaps / RRM measurement occasions, i.e., information indicating whether measurement gaps / RRM measurements or channels / signals are prioritized (e.g., "RRM skip indicator") may be set by RRC.

[0118] In the case of channels / signals other than PDCCH (e.g., per SPS (Semi persistent Scheduling) PDSCH configuration (SPS-Config), CG (Configured Scheduling) PUSCH configuration (CG-Config), CSI-RS configuration, SRS configuration, CSI report configuration, etc.), the "RRM prioritization indicator" may be configured for each channel / signal.

[0119] If the "RRM skip indicator" is configured for the SPS PDSCH / CG PUSCH and the SPS PDSCH / CG PUSCH overlaps with a measurement gap / RRM measurement occasion, the terminal prioritizes the SPS PDSCH / CG PUSCH over the measurement gap / RRM measurement occasion.

[0120] If the "RRM skip indicator" is not configured for the SPS PDSCH / CG PUSCH and the SPS PDSCH / CG PUSCH overlaps with a measurement gap / RRM measurement occasion, the terminal does not prioritize the SPS PDSCH / CG PUSCH over the measurement gap / RRM measurement occasion, i.e., conventional scheduling restrictions apply.

[0121] In Proposal 2, the "RRM Skip Indicator" for a specific semi-statically pre-configured channel / signal transmission / reception opportunity is configured as follows: (1) The "RRM Skip Indicator" is configured by SPS-Config or CG-Config (Alt. 1). (2) The "RRM Skip Indicator" is configured in the measurement configuration (Alt. 2).

[0122] Alt. 1 and Alt. 2 will be explained in detail below.

[0123] (Alt. 1) The "RRM Skip Indicator" may be configured by SPS-Config or CG-Config. If the "Skip Indicator" is configured (as "Enabled") in SPS-Config or CG-Config, the terminal may further determine the skip as follows:

[0124] (Alt. 1-a) The terminal may skip any / all of the measurement gap opportunities / SMTC opportunities / RRM measurement opportunities that overlap with the SPS / CG opportunities of the SPS / CG configuration (regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunities).

[0125] (Alt. 1-b) The terminal may skip a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity of a particular measurement gap configuration / SMTC configuration / RRM measurement configuration if it overlaps with an SPS / CG opportunity of the SPS / CG configuration (regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity).

[0126] The specific measurement gap configuration / SMTC configuration / RRM measurement configuration may be defined by the specification (e.g., per terminal / FR1 / FR2 measurement gap, SMTC configuration / RRM measurement configuration on the same cell as the SPS / CG configuration, etc.) or may be configured by the RRC (for the SPS / CG configuration).

[0127] (Alt. 2) The "RRM skip indicator" may be configured in the "measurement configuration". The "measurement configuration" may be further configured as follows:

[0128] (Alt. 2-1) The "RRM skip indicator" may be configured for all configured measurement gap configurations / SMTC configurations / RRM measurement configurations. For example, the "RRM skip indicator" may be configured by a parameter of MeasConfig or MeasGapConfig (for all measurement gap configurations). If the "skip indicator" is configured (as "enabled"), the terminal may further determine skipping as follows:

[0129] (Alt. 2-1a) The terminal may skip any / all measurement gap opportunities / SMTC opportunities / RRM measurement opportunities that overlap with SPS / CG opportunities of the SPS / CG configuration (regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity).

[0130] (Alt. 2-1b) The terminal may skip any / all measurement gap opportunities / SMTC opportunities / RRM measurement opportunities that overlap with SPS / CG opportunities of a particular SPS / CG configuration (regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity).

[0131] For a particular SPS / CG configuration, the SPS configuration and / or CG configuration index and corresponding cell index can be set, for example, in MeasConfig or MeasGapConfig (for all measurement gap configurations).

[0132] (Alt. 2-2) The "RRM skip indicator" may be configured for each measurement gap configuration / SMTC configuration / RRM measurement configuration. If the "skip indicator" is configured (as "enabled") for a measurement gap configuration / SMTC configuration / RRM measurement configuration, the terminal may further determine skipping as follows:

[0133] (Alt. 2-2a) The terminal may skip a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity of a measurement gap configuration / SMTC configuration / RRM measurement configuration if it overlaps with an SPS / CG opportunity of any SPS / CG configuration (regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity).

[0134] (Alt. 2-2b) The terminal may skip a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity of a measurement gap configuration / SMTC configuration / RRM measurement configuration (regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity) if it overlaps with an SPS / CG opportunity of a specific SPS / CG configuration.

[0135] For a specific SPS / CG configuration, the SPS configuration and / or CG configuration index and the corresponding cell index can be set in the measurement gap configuration / SMTC configuration / RRM measurement configuration.

[0136] (Alt. 2-3) The "RRM skip indicator" may be configured for a subset of the configured measurement gap configurations / SMTC configurations / RRM measurement configurations. The subset of the measurement gap configurations / SMTC configurations / RRM measurement configurations may be defined by a specification or configured by the RRC. If the "skip indicator" is configured (as "enabled"), the terminal may further determine skipping as follows:

[0137] (Alt. 2-3a) The terminal may skip any / all measurement gap opportunities / SMTC opportunities / RRM measurement opportunities of a subset of measurement gap configurations / SMTC configurations / RRM measurement configurations if they overlap with SPS / CG opportunities of any SPS / CG configuration (regardless of whether the SPS / CG opportunities have actual PDSCH / PUSCH).

[0138] (Alt. 2-3b) The terminal may skip any / all measurement gap opportunities / SMTC opportunities / RRM measurement opportunities of a subset of measurement gap configurations / SMTC configurations / RRM measurement configurations (regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunities) if they overlap with SPS / CG opportunities of a specific SPS / CG configuration.

[0139] For a particular SPS / CG configuration, the SPS configuration and / or CG configuration index and corresponding cell index can be configured, for example, in MeasConfig or MeasGapConfig (for a subset of measurement gap configurations).

[0140] (Variations of Proposal 2) Variations of Proposal 2 will be described below.

[0141] The priority indication may only apply to any particular measurement gap / RRM measurement occasion.

[0142] A specific measurement gap may be, for example, a measurement gap for each terminal, a measurement gap for each specific frequency band (e.g., FR1 / FR2), a measurement gap for intra-frequency measurement / inter-frequency measurement, a measurement gap whose gap length is a specific value or within a specific value range, a measurement gap for a specific ID, a measurement gap with a repetition period (provided by mgrp) of a specific value or within a specific value range, etc.

[0143] Furthermore, a specific RRM measurement may be, for example, an RRM measurement with / without a measurement gap, an SSB-based / CSI-RS-based RRM measurement, an intra-frequency / inter-frequency RRM measurement, an RRM measurement of a specific ID (measObjectId, etc.), etc.

[0144] In this case, for other measurement gaps / RRM measurements (not the specific measurement gap / RRM measurement), the priority indication does not apply, i.e. no prioritization is performed and conventional scheduling restrictions apply.

[0145] (Effects of Proposal 2) The above proposal allows prioritizing signal reception or transmission over measurements adaptively and with varying granularity, thereby reducing the impact of scheduling restrictions on measurements under flexible conditions.

[0146] <Proposal 3> In the following, we will explain (Proposal 3) that measurement gaps / scheduling restrictions caused by RRM measurements are skipped based on the transmission / reception of specific quasi-statically pre-configured channels / signals and / or quasi-statically configured "priority information" for specific measurement gaps / scheduling restrictions.

[0147] For skipping methods based on channel / signal priority state values ​​and / or measurement gap / SMTC / RRM priority values, when an SPS / CG opportunity overlaps with a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity, the terminal decides to skip the measurement gap opportunity / SMTC opportunity / RRM measurement opportunity based on the priority value in accordance with (Proposal 3-1) to (Proposal 3-3) below, regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity.

[0148] <Proposal 3-1> Regarding the skipping method based on a comparison between the priority state value of a channel / signal and the priority value of a measurement gap / SMTC / RRM, when an SPS / CG opportunity overlaps with a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity, the terminal decides to skip the measurement gap opportunity / SMTC opportunity / RRM measurement opportunity based on one or more conditions and the priority value of the SPS / CG configuration and the priority value of the measurement gap configuration / SMTC configuration / RRM measurement configuration, regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity.

[0149] The following describes a process by a terminal to prioritize channel / signal transmission / reception over RRM measurements and / or to prioritize either RRM measurements or channel / signal transmission / reception based on one or more conditions.

[0150] One or more conditions for prioritizing transmission / reception of channels / signals over RRM measurements may follow the following procedure.

[0151] One or more conditions may be predefined conditions. For example, a predefined rule as a predefined condition may define when and what signal / channel (transmission / reception) may take precedence over RRM measurements (with / without measurement gaps). Such a condition / rule may be predefined in a standard. The terminal may decide whether to receive / transmit DL / UL channels / signals or perform RRM measurements (e.g., in a measurement gap / SMTC window) based on the predefined condition.

[0152] For example, if there is a DL / UL channel / signal received / transmitted on one or more CCs, and the DL / UL channel / signal overlaps with a measurement gap, or overlaps with an SMTC window (within which an SSB symbol is measured), or overlaps with a CSI-RS symbol measured for RRM measurement, and one or more of the following conditions A1 to A9 are satisfied, the terminal receives / transmits the DL / UL channel / signal and does not perform RRM measurement (e.g., in the measurement gap / SMTC window). Condition A1: The DL / UL channel / signal is a specific channel / signal type (e.g., PDCCH / PDSCH / CSI-RS / PUCCH / PUSCH / SRS (Sounding Reference Signal) etc.). Condition A2: The DL / UL channel / signal is scheduled / triggered by DCI (or activated by DCI or configured by RRC) or scheduled / triggered by a specific DCI format. Condition A3: The DL / UL channel / signal has a low physical layer priority value ("0") / high physical layer priority value ("1") (introduced in Release 16). Condition A4: The DL / UL channel / signal is aperiodic / semi-persistent / periodic. Condition A5: The DL / UL channel / signal is for a specific service type (e.g., for XR / URLLC / eMBB, etc.). Condition A6: Communication is performed in a specific scenario (e.g., in TN / NTN / FR1 / FR2 / licensed band / unlicensed band / FDD / TDD, etc.). Condition A7: The RRM measurement involves a measurement gap or does not involve a measurement gap. Condition A8: The RRM measurement or measurement gap is for intra-frequency measurement or for inter-frequency measurement. Condition A9: The RRM measurement is based on SSB measurement or CSI-RS measurement.

[0153] Conversely, otherwise, the terminal performs RRM measurements (eg, in measurement gaps / SMTC windows) and does not receive / transmit DL / UL channels / signals.

[0154] (Variation 1) The one or more CCs (or carriers) described above may be defined by a standard (for example, Pcell (primary cell) / Pscell (primary secondary cell) / Scell ​​(secondary cell)), may be set by RRC (for example, a list of CCs may be set, or priority processing may be enabled / disabled for each CC), or may be one or more CCs in a specific frequency range (for example, FR1 / FR2).

[0155] (Variation 2) Whether or not priority processing is enabled may be defined by a standard (for example, always enabled (in an enabled state)), may be set by RRC, or may be determined based on the capabilities of terminal 200.

[0156] Proposal 3-1 may be applied to intra-frequency SSB / CSI-RS measurements / inter-frequency SSB / CSI-RS measurements with measurement gaps, and / or intra-frequency SSB / CSI-RS measurements / inter-frequency SSB / CSI-RS measurements without measurement gaps.

[0157] In this application, a measurement gap, an SMTC window, an SSB symbol, a CSI-RS symbol, etc. may be referred to as a period or interval associated with a measurement.

[0158] (Effects of Proposal 3-1) As described above, according to Proposal 3-1, it is possible to prioritize channel / signal transmission / reception over RRM measurements based on conditions, thereby reducing the impact caused by scheduling restrictions on measurements.

[0159] <Proposal 3-2> Regarding the skip method based on the priority state value of a channel / signal, when an SPS (Semi-Persistent Scheduling) / CG (Configured Scheduling) opportunity overlaps with a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity, the terminal determines whether to skip the measurement gap opportunity / SMTC opportunity / RRM measurement opportunity based on the priority value of the SPS / CG configuration according to the following procedure, regardless of whether there is an actual PDSCH / PUSCH within the SPS / CG opportunity.

[0160] Hereinafter, a process for prioritizing a channel / signal over a measurement gap / RRM measurement based on a priority state value of the channel / signal will be described. Note that the "priority state value" is information or a value indicating a priority or order of priority, and may also be referred to as a priority value.

[0161] The base station may notify the terminal of the priority status value of a channel / signal by dynamic instruction (e.g., instruction by scheduling, triggering, activation DCI or MAC CE) and / or by configuration by RRC (Radio Resource Control) (e.g., configuration for each channel type, for each SPS PDSCH configuration, for each CG PUSCH configuration, for each PUCCH resource (set), for each CSI-RS configuration, for each SRS configuration, or for each CSI report configuration). Candidate values ​​for the priority status value of a channel / signal may be defined by a specification, or may be indicated or configured by the base station.

[0162] If the priority status value is indicated in the DCI, this indication may be done via a new DCI field (e.g., "RRM Priority Status Value"), the presence of which may be configured by the base station for the DCI format.

[0163] Furthermore, if the priority status value is indicated in the DCI, this indication may be made via an existing field / bit, for example by reinterpreting an existing field / bit. Whether to reinterpret an existing field / bit for indicating the priority status value or to interpret it based on legacy can be configured by the base station for the DCI format.

[0164] Also, in the case where the priority state value is indicated in the DCI, if the DCI schedules multiple PDSCH / PUSCH, scheduled PDSCH / PUSCH in multiple serving cells, multiple repetitions of PDSCH / PUSCH / PUCCH, etc., the indication field may apply to each PDSCH / PUSCH, PDSCH / PUSCH on each scheduled serving cell, or each repetition of PDSCH / PUSCH / PUCCH.

[0165] If the priority state value of a channel / signal is not specified / configured by the base station, a default value may be defined by the specification. In this case, as a variation, different default values ​​may be defined for different channel / signal types (PDSCH / PUSCH / PUCCH / CSI-RS / SRS, presence / absence of scheduling / triggering DCI, physical priority state value as 1 / 0, periodic / semi-persistent / aperiodic, etc.). Alternatively, as a variation, a common default value may be defined for all channel / signal types.

[0166] For channels / signals that overlap with measurement gaps / RRM measurement occasions, whether the channel / signal is prioritized over the measurement gap / RRM measurement may be determined based on the priority state value of the channel / signal.

[0167] (Alt. 1) A channel / signal may be prioritized over any / all measurement gaps / RRM measurement occasions if its priority status value is equal to a first value or is within a range from a first lower limit value to a first upper limit value. The first value, the first lower limit value, and the first upper limit value may be defined by a specification or may be set by the base station.

[0168] (Alt. 2) A channel / signal may be prioritized over a particular measurement gap / RRM measurement occasion if its priority status value is equal to a second value or is within a range from a second lower limit value to a second upper limit value. The second value, the second lower limit value, and the second upper limit value may be defined by a specification or may be set by the base station.

[0169] A specific measurement gap may be, for example, a measurement gap for each terminal, a measurement gap for each specific frequency band (e.g., FR1 / FR2), a measurement gap for intra-frequency measurement / inter-frequency measurement, a measurement gap whose gap length is a specific value or within a specific value range, a measurement gap for a specific ID, a measurement gap with a repetition period (provided by mgrp) of a specific value or within a specific value range, etc.

[0170] Furthermore, a specific RRM measurement may be, for example, an RRM measurement with / without a measurement gap, an SSB-based / CSI-RS-based RRM measurement, an intra-frequency / inter-frequency RRM measurement, an RRM measurement of a specific ID (measObjectId, etc.), etc.

[0171] In this case, for other measurement gaps / RRM measurements (not the specific measurement gap / RRM measurement), the priority indication does not apply, i.e. no prioritization is performed and conventional scheduling restrictions apply.

[0172] (Alt. 3) If the priority status value of a channel / signal is equal to a third value or is within the range from a third lower limit to a third upper limit, no prioritization of the channel / signal for measurement gaps / RRM measurement occasions may be performed and conventional scheduling restrictions may apply. The third value, the third lower limit, and the third upper limit may be defined by the specification or may be set by the base station.

[0173] Whether the prioritization based on the channel / signal priority state value is Alt. 1 to Alt. 3 may be defined by a specification or may be indicated or set by the base station.

[0174] (Effects of Proposal 3-2) The above proposal makes it possible to adaptively prioritize signal reception or transmission over measurement, thereby reducing the impact of scheduling restrictions on measurements.

[0175] <Proposal 3-3> Regarding the skip method based on the priority status value of MG / SMTC / RRM measurements, when an SPS / CG opportunity overlaps with a measurement gap opportunity / SMTC opportunity / RRM measurement opportunity, the terminal determines whether to skip the measurement gap opportunity / SMTC opportunity / RRM measurement opportunity based on the priority value of MG / SMTC / RRM measurements according to the following procedure, regardless of whether there is an actual PDSCH / PUSCH in the SPS / CG opportunity.

[0176] The following describes support for prioritizing channels / signals over measurement gaps / RRM measurements based on the priority state value of the measurement gaps / RRM measurements.

[0177] The base station can set the priority state value for the measurement gap / RRM measurement.

[0178] The priority status value of a measurement gap may be set individually for each measurement gap (e.g., measurement gap ID), individually for each measurement gap type (e.g., for each terminal, for each specific frequency band (e.g., FR1 / FR2), for intra-frequency measurement / inter-frequency measurement, for a measurement gap whose gap length is a specific value or within a specific range of values, for a measurement gap with a specific ID, or for a measurement gap whose repetition period is a specific value or within a specific range of values ​​(provided by mgrp)), or may be set commonly for all measurement gaps. Candidate values ​​for the priority status value of a measurement gap may be defined by a specification, or may be indicated or set by the base station.

[0179] The priority state value of the RRM measurement may be set individually for each RRM measurement (e.g., RRM measurement ID), individually for each RRM measurement type (e.g., SSB-based / CSI-RS-based, intra-frequency measurement / inter-frequency measurement, with / without measurement gap), or commonly for all RRM measurements. Candidate values ​​for the priority state value of the RRM measurement may be defined by a specification, or may be indicated or set by the base station.

[0180] If the priority state value is not set for the measurement gap / RRM measurement, a default value may be defined by the specification. In this case, as a variation, different default values ​​may be defined for different measurement gap types (e.g., for each UE, for each specific frequency band (e.g., FR1 / FR2), or for different RRM measurement types (e.g., SSB-based / CSI-RS-based, intra-frequency measurement / inter-frequency measurement, with / without gap). Alternatively, as a variation, a common default value may be defined for all measurement gap types / RRM measurement types.

[0181] For channels / signals (e.g., PDSCH / PUSCH) that overlap with measurement gaps / RRM measurement occasions, whether the channel / signal is prioritized over the measurement gap / RRM measurement may be determined based on the priority state value of the measurement gap / RRM measurement.

[0182] (Alt. 1) A channel / signal may be prioritized over any / all measurement gaps / RRM measurement occasions if the priority state value of the measurement gap / RRM measurement is equal to a first value or is within a range from a first lower limit value to a first upper limit value. The first value, the first lower limit value, and the first upper limit value may be defined by a specification or may be set by the base station.

[0183] (Alt. 2) A particular channel / signal may be prioritized over a measurement gap / RRM measurement occasion if the priority state value of the measurement gap / RRM measurement is equal to a second value or is within a range from a second lower limit value to a second upper limit value. The second value, the second lower limit value, and the second upper limit value may be defined by a specification or may be set by the base station.

[0184] The specific channel / signal may be PDSCH / PUSCH / PUCCH / CSI-RS / SRS, presence or absence of scheduling / trigger DCI, physical priority state value as 1 / 0, periodic / semi-persistent / non-periodic, etc.

[0185] In this case, for other channels / signals (not specific channels / signals), the priority indication does not apply, i.e., no prioritization is performed and conventional scheduling restrictions apply.

[0186] (Alt. 3) If the priority state value of a measurement gap / RRM measurement is equal to a third value or is within the range of a third lower limit value to a third upper limit value, no channel / signal prioritization for the measurement gap / RRM measurement occasion is performed and conventional scheduling restrictions may apply. The third value, the third lower limit value, and the third upper limit value may be defined by the specification or may be set by the base station.

[0187] Whether the prioritization based on the priority state value of the measurement gap / RRM measurement is Alt. 1 to Alt. 3 may be defined by a specification or may be indicated or set by the base station.

[0188] (Effects of Proposal 3-3) The above proposal makes it possible to adaptively prioritize signal reception or transmission over measurement, thereby reducing the impact of scheduling restrictions on measurements.

[0189] (Variations of Proposals 3-2 and 3-3) Variations of Proposals 3-2 and 3-3 are described below.

[0190] Whether the priority state (priority) for a channel / signal measurement gap / RRM measurement is determined based on the priority state value of the channel / signal (Proposal 3-2) or based on the priority state value of the gap / RRM measurement (Proposal 3-3) may be defined by the specification or set by the base station.

[0191] Furthermore, whether the priority state (priority) for a channel / signal measurement gap / RRM measurement is determined based on the priority state value of the channel / signal (proposal 3-2), based on the priority state value of the gap / RRM measurement (proposal 3-3), or based on the magnitude relationship between the priority state value of the channel / signal and the priority state value of the gap / RRM measurement (hereinafter referred to as "other proposals") may be defined by the specifications or set by the base station.

[0192] In another proposal, the terminal may prioritize transmission / reception of a channel / signal over measurement gap / RRM measurement if the priority state value of the channel / signal is greater than the priority state value of the gap / RRM measurement, and may prioritize measurement gap / RRM measurement over transmission / reception of a channel / signal if the priority state value of the channel / signal is less than the priority state value of the gap / RRM measurement.

[0193] Alternatively, in another proposal, the terminal may determine the priority state (priority) for the measurement gap / RRM measurement of the channel / signal based on Proposal 3-2 if the priority state value of the channel / signal is greater than the priority state value of the gap / RRM measurement, and may determine the priority state (priority) for the measurement gap / RRM measurement of the channel / signal based on Proposal 3-3 if the priority state value of the channel / signal is less than the priority state value of the gap / RRM measurement.

[0194] <UE capability> The UE capability indicating the capabilities of the terminal may include information indicating some or all of the following new terminal functions and report signaling (and RRC configuration) capabilities in units of terminal / FR / feature set, etc.

[0195] Information defining whether the terminal supports a quasi-static configuration skip pattern for skipping measurement gaps / RRM measurements / SMTC opportunities. Information defining whether the terminal supports a quasi-static configuration skip pattern for measurement gap configuration. Information defining whether the terminal supports a quasi-static configuration skip pattern for SMTC configuration. Information defining whether the terminal supports a quasi-static configuration skip pattern for RRM measurement configuration. Information defining whether the terminal supports an RRM skip indicator set for SPS / CG configuration.

[0196] <Configuration of Base Station> Fig. 11 is a block diagram showing an example of the configuration of a base station according to this embodiment. The base station includes, for example, a transmitting unit 101, a receiving unit 102, and a control unit 103. The base station communicates with a terminal (see Fig. 12) by radio. The base station 10 may be an intermediate node, a support node, or a terminal (a terminal of an SL that communicates with the device 20).

[0197] The transmitter 101 transmits a downlink (DL) signal to a terminal. For example, the transmitter 101 transmits a DL signal (for example, the above-mentioned RRC, SIB, MAC CE, DCI, notification, confirmation, etc.) under the control of the controller 103.

[0198] The DL signal may include, for example, a downlink data signal and control information (e.g., Downlink Control Information (DCI)). The DL signal may also include information indicating scheduling related to terminal signal transmission (e.g., an UL grant). The DL signal may also include control information of higher layers (e.g., control information of Radio Resource Control (RRC)). The DL signal may also include a reference signal.

[0199] Channels used for transmitting DL signals include, for example, a downlink data channel and a downlink control channel. For example, the downlink data channel may include a PDSCH (Physical Downlink Shared Channel), and the downlink control channel may include a PDCCH (Physical Downlink Control Channel). For example, a base station transmits downlink control information to a terminal using the PDCCH and transmits downlink data signals using the PDSCH.

[0200] The reference signal included in the DL signal may include at least one of a demodulation reference signal (Demodulation Reference Signal (DMRS)), a Phase Tracking Reference Signal (PTRS), a Channel State Information-Reference Signal (CSI-RS), a Sounding Reference Signal (SRS), and a Positioning Reference Signal (PRS) for position information. For example, reference signals such as DMRS and PTRS are used for demodulating downlink data signals and are transmitted using the PDSCH.

[0201] The receiving unit 102 receives an uplink (UL) signal transmitted from a terminal. For example, the receiving unit 102 receives an UL signal (e.g., the above-mentioned request, notification, etc.) under the control of the control unit 103.

[0202] The transmitting unit 101 and the receiving unit 102 may be collectively referred to as a communication unit.

[0203] The control unit 103 controls the communication operations of the base station, including the transmission processing of the transmission unit 101 and the reception processing of the reception unit 102 .

[0204] For example, the control unit 103 acquires information such as data and control information from the upper layer and outputs it to the transmitting unit 101. The control unit 103 also outputs the data, control information, etc. received from the receiving unit 102 to the upper layer.

[0205] For example, the control unit 103 allocates resources (or channels) used for transmitting and receiving DL signals and / or resources used for transmitting and receiving UL signals based on signals (e.g., data and control information, etc.) received from the terminal and / or data and control information, etc. acquired from a higher layer. Information on the allocated resources may be included in control information transmitted to the terminal.

[0206] 12 is a block diagram showing an example of the configuration of a terminal according to this embodiment. The terminal includes, for example, a receiving unit 201, a transmitting unit 202, and a control unit 203. The terminal communicates with, for example, a base station wirelessly.

[0207] In relation to proposals 1 to 3, for example, the receiving unit 201 may receive a signal from the base station at the above timing in accordance with the judgment of the control unit 203 when the period for receiving a signal overlaps with a period associated with RRM measurements (measurement gap opportunity, SMTC window, etc.).

[0208] The transmitter 202 transmits an UL signal to the base station. For example, the transmitter 202 transmits an UL signal (for example, the above-mentioned request, notification, etc.) under the control of the controller 203.

[0209] In relation to proposals 1 to 3, for example, the transmitting unit 202 may transmit a signal to the base station at the above timing in accordance with the judgment of the control unit 203 when the period for transmitting a signal overlaps with a period associated with RRM measurements (measurement gap opportunity, SMTC window, etc.).

[0210] The UL signal may include, for example, an uplink data signal and control information (e.g., UCI), information related to the processing capabilities of the terminal (e.g., UE capability), and a reference signal.

[0211] Channels used for transmitting UL signals include, for example, an uplink data channel and an uplink control channel. For example, the uplink data channel includes a PUSCH (Physical Uplink Shared Channel), and the uplink control channel includes a PUCCH (Physical Uplink Control Channel). For example, a terminal transmits uplink control information to a base station using the PUCCH and transmits uplink data signals using the PUSCH.

[0212] 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, the reference signals such as DMRS and PTRS are used for demodulating the uplink data signal and are transmitted using an uplink channel (for example, PUSCH).

[0213] The receiving unit 201 and the transmitting unit 202 may be collectively referred to as a communication unit.

[0214] The control unit 203 controls the communication operations of the terminal, including the reception processing in the receiving unit 201 and the transmission processing in the transmitting unit 202 .

[0215] For example, the control unit 203 acquires information such as data and control information from the upper layer and outputs it to the transmitting unit 202. Also, the control unit 203 outputs, for example, the data and control information received from the receiving unit 201 to the upper layer.

[0216] For example, the control unit 203 controls transmission of information to be fed back to the base station. The information to be fed back to the base station may include, for example, HARQ-ACK, Channel State Information (CSI), or Scheduling Request (SR). The information to be fed back to the base station may be included in UCI.

[0217] In relation to Proposals 1 to 3, for example, the control unit 203 may determine whether to receive or transmit a signal or perform measurement using a measurement signal when a period for receiving or transmitting a signal overlaps with a period associated with RRM measurement (such as a measurement gap opportunity or an SMTC window). For example, the control unit 203 may make the above determination based on information indicating the priority of the signal and the period and / or measurement, predefined conditions, etc. For example, the control unit 203 may further make the above determination when a signal is received or transmitted in a specific cell (such as a Pcell) or carrier (such as a CC).

[0218] Note that the channel used for transmitting the DL signal and the channel used for transmitting the UL signal are not limited to the above-mentioned example. For example, the channel used for transmitting the DL signal and the channel used for transmitting the UL signal may include a Random Access Channel (RACH) and a Physical Broadcast Channel (PBCH). The RACH may be used to transmit Downlink Control Information (DCI) including a Random Access Radio Network Temporary Identifier (RA-RNTI), for example.

[0219] The above configuration can reduce the impact of scheduling restrictions on measurements.

[0220] <Hardware Configuration, etc.> The block diagrams used to explain the above embodiments show functional blocks. These functional blocks (components) are realized by any combination of at least one of hardware and software. Furthermore, the method for realizing each functional block is not particularly limited. That is, each functional block may be realized using a single device that is physically or logically coupled, or may be realized using two or more physically or logically separated devices that are directly or indirectly connected (for example, using wires, wirelessly, etc.) and these multiple devices. The functional block may be realized by combining software with the single device or the multiple devices.

For example, the embodiments of the present disclosure may be applied to a configuration in which communication between a base station and a terminal is replaced with communication between multiple terminals (which may be called, for example, D2D (Device-to-Device) or V2X (Vehicle-to-Everything)). In this case, the terminal may be configured to have the functions of the base station described above.

[0266] The communication module 2013 is a communication device that can be controlled by the microprocessor 2031 of the electronic control unit 2010 and can communicate with an external device. For example, it transmits and receives various information to and from the external device via wireless communication. The communication module 2013 may be located either inside or outside the electronic control unit 2010. The external device may be, for example, a base station, a mobile station, or the like.

[0272] <Meaning of "based on"> As used in this disclosure, the phrase "based on" does not mean "based only on," unless expressly stated otherwise. In other words, the phrase "based on" means both "based only on" and "based at least on."

[0273] "First," "Second" Any reference to an element using designations such as "first," "second," etc., used in this disclosure does not generally limit the quantity or order of those elements. These designations may be used in this disclosure as a convenient method of distinguishing between two or more elements. Thus, a reference to a first and a second element does not imply that only two elements may be employed or that the first element must in some way precede the second element.

[0274] <Means> The "means" in the configuration of each device above may be replaced with "section," "circuit," "device," or the like.

[0275] Open Format: When the terms "include," "including," and variations thereof are used in this disclosure, these terms are intended to be inclusive, similar to the term "comprising." Furthermore, when the term "or" is used in this disclosure, it is not intended to be an exclusive or.

[0276] <Time Units such as TTI, Frequency Units such as RB, and Radio Frame Configuration> A radio frame may be composed of one or more frames in the time domain. Each of the one or more frames in the time domain may be called a subframe. A subframe may further be composed of one or more slots in the time domain. A subframe may have a fixed time length (e.g., 1 ms) that is independent of numerology.

[0277] Numerology may be a communication parameter applied to the transmission and / or reception of a signal or channel, and may indicate, for example, at least one of subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame structure, specific filtering operations performed by the transceiver in the frequency domain, specific windowing operations performed by the transceiver in the time domain, etc.

[0278] A slot may be composed of one or more symbols (such as an Orthogonal Frequency Division Multiplexing (OFDM) symbol or a Single Carrier Frequency Division Multiple Access (SC-FDMA) symbol) in the time domain. A slot may be a time unit based on numerology.

[0279] A slot may include multiple minislots. Each minislot may consist of one or multiple symbols in the time domain. A minislot may also be called a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in a time unit larger than a minislot may be called PDSCH (or PUSCH) mapping type A. A PDSCH (or PUSCH) transmitted using a minislot may be called PDSCH (or PUSCH) mapping type B.

[0280] The radio frame, subframe, slot, minislot, and symbol all represent time units for transmitting signals, and may be referred to by other names corresponding to the radio frame, subframe, slot, minislot, and symbol.

[0281] For example, one subframe may be called a transmission time interval (TTI), multiple consecutive subframes may be called a TTI, or one slot or one minislot may be called a TTI. That is, at least one of the subframe and the TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (for example, 1-13 symbols), or a period longer than 1 ms. Note that the unit representing the TTI may be called a slot, minislot, etc. instead of a subframe.

[0282] Here, TTI refers to, for example, the smallest time unit for scheduling in wireless communication. For example, in an LTE system, a base station performs scheduling to allocate radio resources (such as frequency bandwidth and transmission power that can be used by each user terminal) to each user terminal in TTI units. Note that the definition of TTI is not limited to this.

[0283] The TTI may be a transmission time unit for a channel-encoded data packet (transport block), a code block, a code word, etc., or may be a processing unit for scheduling, link adaptation, etc. When a TTI is given, the time interval (e.g., the number of symbols) to which the transport block, code block, code word, etc. are actually mapped may be shorter than the TTI.

[0284] When one slot or one minislot is called a TTI, one or more TTIs (i.e., one or more slots or one or more minislots) may be the minimum time unit for scheduling. Also, the number of slots (minislots) constituting the minimum time unit for scheduling may be controlled.

[0285] A TTI having a time length of 1 ms may be called a regular TTI (TTI in LTE Rel. 8-12), normal TTI, long TTI, regular subframe, normal subframe, long subframe, slot, etc. A TTI shorter than a regular TTI may be called a shortened TTI, short TTI, partial or fractional TTI, shortened subframe, short subframe, minislot, subslot, slot, etc.

[0286] In addition, a long TTI (e.g., a normal TTI, a subframe, etc.) may be interpreted as a TTI having a time length of more than 1 ms, and a short TTI (e.g., a shortened TTI, etc.) may be interpreted as a TTI having a TTI length shorter than that of a long TTI and greater than or equal to 1 ms.

[0287] A resource block (RB) is a resource allocation unit in the time domain and the frequency domain, and may include one or more consecutive subcarriers in the frequency domain. The number of subcarriers included in an RB may be the same regardless of numerology, for example, 12. The number of subcarriers included in an RB may be determined based on numerology.

[0288] The time domain of an RB may include one or more symbols and may have a length of one slot, one minislot, one subframe, or one TTI. One TTI, one subframe, etc. may each be composed of one or more resource blocks.

[0289] Note that one or more RBs may also be called a physical resource block (PRB), a sub-carrier group (SCG), a resource element group (REG), a PRB pair, an RB pair, etc.

[0290] Furthermore, a resource block may be composed of one or more resource elements (REs). For example, one RE may be a radio resource region of one subcarrier and one symbol.

[0291] A Bandwidth Part (BWP) (which may also be referred to as a partial bandwidth) may represent a subset of contiguous common resource blocks (RBs) for a given numerology on a given carrier, where the common RBs may be identified by their index relative to a Common Reference Point of the carrier. PRBs may be defined in a BWP and numbered within the BWP.

[0292] The BWP may include a BWP for UL (UL BWP) and a BWP for DL ​​(DL BWP). One or more BWPs may be configured for a UE within one carrier.

[0293] At least one of the configured BWPs may be active, and the UE may not expect to transmit or receive a given signal / channel outside the active BWP. Note that the terms "cell," "carrier," etc. in this disclosure may be read as "BWP."

[0294] The above-described structures of radio frames, subframes, slots, minislots, symbols, etc. are merely examples, and various changes can be made to the number of subframes included in a radio frame, the number of slots per subframe or radio frame, the number of minislots included in a slot, the number of symbols and RBs included in a slot or minislot, the number of subcarriers included in an RB, the number of symbols in a TTI, the symbol length, the cyclic prefix (CP) length, etc.

[0295] <Maximum Transmit Power> The "maximum transmit power" in the present disclosure may refer to the maximum value of transmit power, the nominal UE maximum transmit power, or the rated UE maximum transmit power.

[0296] Articles In this disclosure, where articles are added by translation, such as a, an, and the in English, the disclosure may include that the nouns following these articles are in the plural form.

[0297] <"Different"> In the present disclosure, the term "A and B are different" may mean "A and B are different from each other." Note that the term may also mean "A and B are each different from C." Terms such as "separate" and "coupled" may also be interpreted in the same way as "different."

[0298] One aspect of the present disclosure is useful in wireless communication systems.
