Description

Terminal, wireless communication method and base station

The present disclosure relates to terminals, wireless communication methods, and base stations in next-generation mobile communication systems.

In the Universal Mobile Telecommunications System (UMTS) network, Long Term Evolution (LTE) has been specified for the purpose of further high data rate, low delay, etc. (Non-Patent Document 1). In addition, LTE-Advanced (3GPP Rel. 10-14) has been specified for the purpose of further increasing the capacity and sophistication of LTE (Third Generation Partnership Project (3GPP) Release (Rel.) 8, 9).

LTE successor systems (for example, 5th generation mobile communication system (5G), 5G+ (plus), 6th generation mobile communication system (6G), New Radio (NR), 3GPP Rel. 15 and later) are also being considered. .

In future wireless communication systems (for example, NR), it is assumed that multiple user terminals (user terminals, user equipment (UE)) will communicate in an ultra-high-density and high-traffic environment.

Under such an environment, it is assumed that uplink (UL) resources will be insufficient compared to downlink (DL) resources.

However, in the NR specifications so far, sufficient consideration has not been given to methods for increasing uplink resources. Failure to properly control the method may result in degraded system performance, such as increased delay and reduced coverage performance.

Therefore, one of the purposes of the present disclosure is to provide a terminal, a wireless communication method, and a base station that improve resource utilization efficiency.

A terminal according to an aspect of the present disclosure includes a receiving unit that receives an indication of a link direction for a first time resource and availability of some frequency resources within the first time resource; and a control unit for controlling uplink transmission or downlink reception on the frequency resource within the first time resource based on.

According to one aspect of the present disclosure, resource utilization efficiency can be improved.

(TDD setting)
Rel. At 15, the UE is configured for UL and DL (UL and DL resources) in Time Division Duplex (TDD). The UE receives higher layer parameters for cell-specific UL/DL TDD configuration (TDD-UL-DL-ConfigCommon) or higher layer parameters for UE-specific UL/DL TDD configuration (TDD-UL-DL-ConfigDedicated). You may

The cell-specific UL/DL TDD configuration related upper layer parameters (TDD-UL-DL-ConfigCommon) include a parameter for setting reference subcarrier spacing (referenceSubcarrierSpacing) and a parameter for TDD UL and DL patterns (TDD- UL-DL-Pattern) and

TDD-UL-DL-Pattern includes a parameter for setting the period of the DL-UL pattern (dl-UL-TransmissionPeriodicity), a parameter for setting the number of consecutive DL slots (nrofDownlinkSlots), and a parameter for setting the number of consecutive DL symbols. (nrofDownlinkSymbols), a parameter for setting the number of consecutive UL slots (nrofUplinkSlots) and a parameter for setting the number of consecutive UL symbols (nrofUplinkSymbols).

　The slot setting and the slot index setting are performed with the higher layer parameter (TDD-UL-DL-ConfigDedicated) related to the UE-specific UL/DL TDD setting.

　Slot settings are performed by the parameter TDD-UL-DL-SlotConfig. TDD-UL-DL-SlotConfig includes a parameter (TDD-UL-DL-SlotIndex) related to the slot index and a parameter (symbols) related to the symbols forming the slot. The parameters (symbols) related to the symbols that make up the slot include a parameter (allDownlink) that indicates that all the symbols that make up the slot are used for DL, a parameter (allUplink) that indicates that all the symbols that make up the slot are used for UL, Alternatively, set one of the parameters (explicit) that explicitly indicate the number of symbols.

Parameters (explicit) that explicitly indicate the number of symbols include a parameter (nrofDownlinkSymbols) for setting the number of DL symbols and a parameter (nrofUplinkSymbols) for setting the number of UL symbols.

The UE determines the slots/symbols to use for transmission of UL signals/channels and/or reception of DL signals/channels based on the parameters described above.

(XDD)
Rel. Considering a time ratio of transmission and reception with Time Division Duplex (TDD) up to 16 (e.g., DL:UL=4:1), the transmission opportunities of UL signals/channels are reduced to the reception of DL signals/channels. It is conceivable that there may be cases where the amount is less than the opportunity. In such a case, the UE may not be able to transmit UL signals/channels frequently, which may cause delays in transmission of critical UL signals/channels. Signal/channel congestion at UL transmission opportunities is also a concern, as there are fewer UL transmission opportunities compared to DL reception opportunities. Furthermore, in TDD, the time resource for transmitting UL signals/channels is limited, so the application of UL coverage extension technology by, for example, repetition transmission (Repetition) is also limited.

In future wireless communication systems (eg, Rel.17/18 and later), a division duplex method that combines TDD and Frequency Division Duplex (FDD) for UL and DL will be introduced. is being considered.

The division duplex method may be called XDD (Cross Division Duplex). XDD may refer to a duplexing method that frequency division multiplexes the DL and UL within one component carrier (CC) of the TDD band (DL and UL can be used simultaneously).

　Figure 1A shows the Rel. 16 is a diagram showing an example of setting of TDD defined up to 16. FIG. In the example shown in FIG. 1A, a UE is configured with TDD slots/symbols in the bandwidth of one component carrier (CC) (cell, which may also be called a serving cell).

In the example shown in FIG. 1A, the time ratio between DL slots and UL slots is 4:1. With such a conventional TDD slot/symbol setting, sufficient UL time resources cannot be secured, and there is a risk of occurrence of UL transmission delay and degradation of coverage performance.

FIG. 1B is a diagram showing an example of the configuration of XDD. In the example of FIG. 1B, resources used for DL reception and resources used for UL transmission overlap in time within one component carrier (CC). According to such a resource configuration, it is possible to secure UL resources and improve the utilization efficiency of resources.

For example, as in the example shown in FIG. 1B , both ends of the frequency domain in one CC are configured as DL, and by configuring the DL to sandwich the UL resource, cross-link interference with neighboring carriers (Cross It is possible to avoid and mitigate the occurrence of Link Interference (CLI). Also, a guard area may be set at the boundary between the DL resource and the UL resource.

Considering the complexity of self-interference processing, it is conceivable that only the base station uses DL resources and UL resources at the same time. That is, in resources where DL and UL temporally overlap, a configuration may be adopted in which one UE uses DL resources and another UE uses UL resources.

FIG. 2 is a diagram showing an example of the configuration of XDD. In the example shown in FIG. 2, a part of the DL resource of the TDD band is used as the UL resource, and the DL and the UL are partially overlapped in terms of time.

In the example shown in FIG. 2, each of the multiple UEs (UE#1 and UE#2 in FIG. 2) receives the DL channel/signal during the DL-only period.

Also, in the period when the DL and UL temporally overlap, a certain UE (UE # 1 in the example of FIG. 2) performs reception of the DL channel / signal, and another UE (UE # 2 in the example of FIG. 2 ) carries out the transmission of the UL channels/signals. During this period, the base station performs simultaneous DL and UL transmission and reception.

Furthermore, during UL-only periods, each of the multiple UEs transmits UL channels/signals.

In the existing NR (for example, defined by Rel.15/16), the DL frequency resource and UL frequency resource in the UE carrier are set as DL bandwidth part (BWP) and UL BWP, respectively. be. In order to switch a DL/UL frequency resource to another DL/UL frequency resource, multiple BWP configurations and a BWP adaptation mechanism are required.

Also, in the existing NR, the time resource in the TDD carrier for UE is configured as at least one of DL, UL and flexible (FL) in TDD configuration.

How to configure time domain and frequency domain resources for XDD operation is being considered. For example, for UE #1 in FIG. 2, by setting the XDD resource (the period in which DL and UL overlap) in the same way as the existing DL resource (for example, using frequency domain resource allocation (FDRA) (while avoiding using part of the UL resource for the UE), the impact on the specification/UE can be minimized (see Figure 3A).

Further, for example, for UE #2 in FIG. 2, by setting the XDD resource in the same manner as the existing UL resource (for example, using frequency domain resource allocation (FDRA), the DL resource part can be used (while avoiding

However, each UE needs to know whether resources are being used for XDD operations.

For example, for UE #1 as shown in FIG. 2, the portion where DL and UL overlap in the TDD band (may be called XDD portion) can be configured as DL. However, it is not clear whether or not to configure frequency resources for the XDD part separately from frequency resources for the DL only part (for example, the DL part other than the XDD part).

Since the UL part of the frequency resource of the XDD part can be used for UL transmission by another UE (eg, UE #2 in FIG. 2), when DL reception is performed in this part (UL part of the XDD part), the CLI It is feared that it will occur. It is also being considered to disable the DL resource allocation to this part in order to allocate the remaining resources other than that part to a single UE.

In other words, it is considered necessary to configure DL resources in XDD separately from DL in TDD band.

Also, when it is necessary to process DL resources in XDD and DL resources not in XDD separately, set these resources as separate frequency resources (for example, DL BWP), and BWP adaptation for switching these resources Consideration is being given to introducing a mechanism.

However, requiring UE capabilities for multiple BWP configuration and BWP adaptation may not be preferable due to the difference between the functionality required for XDD operation and the functionality required for operation with multiple BWPs.

The above can be considered the same for UL. For example, for UE #2 as shown in FIG. 2, the overlapping portion of DL and UL in the TDD band (which may be referred to as the XDD portion) may be configured as UL. However, it is not clear whether frequency resources for the XDD part are set separately from frequency resources for the UL only part (for example, the UL part other than the XDD part).

For example, in order to minimize adverse effects of CLI, it is being considered to configure UL transmission (eg, filtering) in the XDD part differently than UL resources that are not in the XDD part.

In other words, it is considered necessary to set UL resources in XDD separately from UL in the TDD band.

Also, when it is necessary to process UL resources in XDD and UL resources not in XDD separately, these resources are set as separate frequency resources (for example, UL BWP), and BWP adaptation for switching these resources Consideration is being given to introducing a mechanism.

However, due to the difference between the functionality required for XDD operation and the functionality required for operation with multiple BWPs, it is preferable to require existing UE capabilities for multiple BWP configuration and BWP adaptation for XDD operation. It is possible that there is none.

Also, when the link direction (DL/UL/flexible) is set/indicated, it is not clear whether each UE can use part of the frequency resource. If the availability of frequency resources is not clear, proper transmission and reception cannot be performed, and communication quality/communication throughput may deteriorate.

We therefore propose a method for controlling XDD operation, link direction and partial frequency resource availability without exceeding UE capacity and/or inefficiency (e.g. switching delay of BWP). I came up with the idea of a control method for

<First Embodiment>
In the first embodiment, XDD DL frequency resources will be described.

<<Embodiment 1-1>>
[Embodiment 1-1-1]
In the embodiment 1-1, in the XDD operation, a DL BWP (new DL BWP, DL BWP for XDD) using continuous or non-continuous PRBs may be set. The UE may be configured with DL BWP with contiguous or non-contiguous PRBs in XDD operation.

In the present disclosure, for BWP using XDD, an example in which one UL resource is allocated between two DL resources in the frequency domain of one CC, as shown in FIG. 2, will be mainly described. /UL resource placement/allocation is not limited to this example. One DL resource may be allocated so as to be sandwiched between two UL resources. Allocation of two DL resources in the frequency domain of one CC may mean that DL BWP using non-contiguous PRBs is configured. Conversely, in the frequency domain of one CC, allocating one DL resource may mean that a DL BWP using continuous PRBs is configured.

Regarding PRB settings for DL BWP, the UE sets total frequency resources (continuous frequency resources including frequency resources that can be used for DL and frequency resources that cannot be used for DL) and frequency resources that cannot be used for DL resources. may be The total frequency resource may be configured using existing BWP parameters, such as the starting PRB (position) and the number of PRBs (bandwidth). Frequency resources that cannot be used for DL resources may be configured using, for example, (the location of) the starting PRB and the number of PRBs (bandwidth).

Also, regarding the configuration of PRBs for DL BWP, the UE may be configured with available frequency resources. Frequency resources that cannot be used for DL resources may be configured, for example, using multiple (eg, two) sets of starting PRB (position) and number of PRBs (bandwidth).

[Embodiment 1-1-2]
The setting of the new DL BWP may be set as a DL BWP supplementary to the normal DL BWP. Auxiliary DL BWP may be associated with normal DL BWP. A supplemental DL BWP may be referred to as a supplemental DL BWP, an additional DL BWP, and so on.

A setting limit may be defined for the normal DL BWP and the supplemental DL BWP. For example, even if at least one of the center frequency, subcarrier spacing, subset of frequency resources (start position/bandwidth), and settings related to DL BWP settings are common between normal DL BWP and supplemental DL BWP good. Settings related to DL BWP settings are, for example, at least one of PDCCH settings (PDCCH Config), PDSCH settings (PDSCH Config), SPS settings (SPS Config), radio link monitoring (RLM) settings (RLM Config). There may be. Also, for example, for normal DL BWP and supplemental DL BWP, at least one of center frequency, subcarrier spacing, subset of frequency resources (start position/bandwidth), and settings related to BWP settings are set separately. may

The association between the new DL BWP (auxiliary DL BWP) and the normal DL BWP may be configured in a specific number ratio. The new DL BWP (auxiliary DL BWP) and normal DL BWP may be associated 1:1, 1:N (N is an integer of 2 or more), or N:1. or N:M (M may be an integer equal to or greater than 2, and N=M).

Also, the setting of the new DL BWP does not have to be associated with the normal DL BWP.

[Embodiment 1-1-3]
The configuration of the DL BWP may be done in conjunction with a UL BWP (new UL BWP, UL BWP for XDD, paired UL BWP) composed of PRBs not allocated for the DL BWP.

Also, the setting of the new DL BWP may be performed together with at least one of the setting of the UL BWP (new UL BWP) in XDD and the setting of the normal UL BWP.

Also, the setting of the new DL BWP may not be associated with the setting of the new UL BWP. In other words, setting the new DL BWP and setting the new UL BWP may be performed separately.

Note that there may be the same restrictions between the DL BWP settings for XDD and the related UL BWP settings as between the normal DL BWP settings and the normal UL BWP settings. Also, there may be different restrictions between the DL BWP settings for XDD and the associated UL BWP settings than between the normal DL BWP settings and the normal UL BWP settings. For example, the limitation may be that the center frequencies are different between the DL BWP setting for XDD and the associated UL BWP setting. The restriction may also be that the PRBs in the DL BWP settings for XDD and the associated UL BWP settings do not overlap in the frequency domain.

<<Embodiment 1-2>>
In embodiments 1-2, semi-static configuration of DL BWP switching patterns in the time domain may be supported.

According to this switching pattern, the switching between pure DL resources (DL resources/DL BWP in which all frequencies in the DL resources are available for DL) and DL resources in XDD (new DL BWP) can be performed automatically. This can be done without the typical BWP switch indication and the delay time required for existing switching.

[Embodiment 1-2-1]
The switching pattern of the DL BWP may be done based on the TDD settings.

The UE may determine/judgment the DL BWP switching pattern based on the RRC information element regarding the TDD configuration (eg, TDD-UL-DL-Config). For example, the DL BWP switching pattern may be included in the RRC information element for TDD configuration (eg, TDD-UL-DL-Config).

For example, in addition to normal DL/UL/FL, information on DL/UL on XDD may be included in an RRC information element on TDD configuration (eg, TDD-UL-DL-Config).

In this disclosure, DL/UL for XDD, unavailable DL/UL resource, available DL/UL resource, XDD DL/UL, partial DL/UL, partially available DL/UL resource, Partially unavailable DL/UL resource, invalid DL/UL resource, invalid resource block, invalid resource block pattern, partial pattern may be read interchangeably.

Also, the UE may determine/judgment the DL BWP switching pattern based on the RRC information element (for example, BWP-Config) regarding the BWP configuration. For example, the DL BWP switching pattern may be included in an RRC information element (eg, BWP-Config) regarding BWP configuration.

For example, an RRC information element related to BWP configuration (eg, BWP-Config) may include the period and (time) offset of DL resources in XDD. The period and offset may be expressed in a specific time unit (eg, slot, symbol), or may be expressed in arbitrary time.

Also, the UE may determine/judgment the DL BWP switching pattern based on the RRC information element regarding the BWP configuration in XDD. The RRC control element is Rel. 17 or later, or RRC information elements related to existing TDD settings (e.g., TDD-UL-DL-Config) and RRC information elements related to BWP settings (e.g., BWP-Config) may be a parameter of

[Embodiment 1-2-2]
Restrictions on setting the switching pattern of the DL BWP may be specified.

Restrictions on the time domain location of XDD DL resources may be defined. For example, DL resources in XDD may be restricted to be set temporally after normal DL resources and/or temporally before normal UL resources.

Also, for example, DL resources in XDD may be restricted so that they are set only to specific resources. The specific resource may be, for example, a resource (eg, slot) to which the UL and DL are assigned. Also, the specific resource may be, for example, a resource (for example, a slot) in which the rest of the XDD other than the DL resource is a normal UL resource (symbol). Also, the specific resource may be, for example, a slot that does not include an SS/PBCH block.

For example, DL resources in XDD may be restricted to be set temporally before normal DL resources and/or temporally after normal UL resources.

　The existing (defined in Rel. 15/16) DL/UL BWP settings and BWP switching are performed based on settings/instructions from the network (eg, base station). Existing DL/UL BWP configuration and BWP switching may be performed based on a predetermined timer and a specific DCI format (for example, DCI format 0_1, 0_2, 1_1, or 1_2).

FIG. 4A is a diagram showing an example of switching between existing DL/UL BWP (equivalent to pure DL BWP and pure UL BWP). In the example shown in FIG. 4A, the UE performs DL/UL BWP switching in TDD (DL BWP#1 to DL BWP#2 and UL BWP#1 to UL (switching to BWP#2). In the diagram of FIG. 4A, the resource in the BWP frequency direction increases due to switching.

Note that in the diagram shown in FIG. 4A, the center frequency of the DL BWP in TDD and the center frequency of the UL BWP are the same, and are indicated by broken lines. In the diagram shown in FIG. 4B as well, the center frequency of the DL BWP in TDD and the center frequency of the UL BWP are the same, and are indicated by dashed lines. In this disclosure, a case where the DL BWP and the UL BWP have the same center frequency will be described, but the DL BWP and the UL BWP may have different center frequencies.

　The following describes DL/UL BWP settings and BWP switching in XDD.

The UE may be configured with DL/UL BWP (BWP pattern) in XDD using higher layer signaling (RRC signaling). The UE, based on at least one of the BWP switching pattern configuration included in the RRC configuration, a predetermined timer, and a specific DCI format (eg, BWP configuration/indication included in DCI), XDD DL/ UL BWP setting and BWP switching may be set/instructed.

FIG. 4B is a diagram showing an example of DL/UL BWP switching in XDD. In the example shown in FIG. 4B, the UE is set with DL BWP#1 as the pure DL BWP and DL BWP#1a as the DL BWP in XDD. Also, in the example shown in FIG. 4B, the UE is set with UL BWP #1 as the pure UL BWP and UL BWP #1a as the UL BWP in XDD.

DL BWP#1 and DL BWP#1a may be associated with each other. Also, UL BWP#1 and UL BWP#1a may be associated with each other. Also, DL BWP#1 and UL BWP#1 may be associated with each other. DL BWP#1a and UL BWP#1a may be associated with each other.

In the example shown in FIG. 4B, the UE is configured with a DL/UL BWP switching pattern. The switching pattern may be information for setting switching between DL/UL BWP#1 and DL/UL BWP#1a. The switching pattern includes at least one of the timing of switching between the normal DL/UL resource and the DL/UL resource in XDD, and the period of the configuration including the normal DL/UL resource and the DL/UL resource in XDD. may be information indicating The UE decides/judges DL and UL resources based on the switching pattern.

<<Embodiment 1-3>>
In embodiments 1-3, dynamic adaptation of DL BWP between pure DL resources and DL resources in XDD may be supported.

The UE determines/judges dynamic adaptation of DL BWP between pure DL resources and DL resources in XDD based on at least one of DCI, MAC CE, and specific conditions. good too.

Dynamic adaptation of DL BWP for XDD may mean switching between normal DL BWP and DL BWP in XDD.

Dynamic adaptation of DL BWP for XDD may mean activation/deactivation of DL BWP in XDD associated with normal DL BWP.

The UE may apply the DL BWP adaptation only for a specific period after receiving the DL BWP adaptation instruction (Embodiment 1-3-1). The particular time period may be one or more slots/symbols. The particular time period may be indicated by an offset from the slot/symbol in which the indication is transmitted/received. The particular time period may be indicated by a particular number of slots/symbols. The specific period/offset may be predefined in the specification, configured/notified in higher layer signaling, or dynamically indicated in DCI.

Also, the UE may apply DL BWP adaptation after receiving a DL BWP adaptation instruction until receiving a next DL BWP adaptation instruction (Embodiment 1-3-2). In other words, after receiving an indication for DL BWP adaptation, the UE may apply DL BWP adaptation until receiving an indication to cancel/override the indication.

Also, after receiving an instruction regarding DL BWP adaptation, the UE may apply DL BWP adaptation until a specific condition is met (Embodiment 1-3-3). The particular condition may be, for example, expiration of a particular timer.

At least two of the methods described in Embodiments 1-3-1 to 1-3-3 above may be applied in combination.

At least one of the switching delay and indication mechanisms/conditions for BWP adaptation shall be the same as the existing (specified in Rel. 15/16) switching delay and at least one of the indication mechanisms/conditions. may be different. For example, the delay required for switching the DL BWP adaptation in XDD may be set/defined shorter (or longer) than the existing delay time.

FIG. 5 is a diagram showing an example of BWP adaptation in XDD. In the example shown in FIG. 5, the UE has DL BWP#1 and DL BWP#2 set as pure DL BWP. In addition, DL BWP#1a and DL BWP#2a are set as DL BWPs in XDD for the UE. In addition, UL BWP#1 and UL BWP#2 are set for the UE as pure UL BWP. In addition, UL BWP#1a and UL BWP#2a are set for the UE as UL BWPs in XDD.

In the example shown in FIG. 5, as in FIGS. 4A and 4B, broken lines indicate the center frequencies of the DL BWP and the UL BWP, and the center frequencies of the DL and UL match.

DL BWP#1 and DL BWP#1a may be associated with each other. Also, UL BWP#1 and UL BWP#1a may be associated with each other.

DL BWP#2 and DL BWP#2a may be associated with each other. Also, UL BWP#2 and UL BWP#2a may be associated with each other.

DL BWP#1 and UL BWP#1 may be associated with each other. DL BWP#1a and UL BWP#1a may be associated with each other.

DL BWP#2 and UL BWP#2 may be associated with each other. DL BWP#2a and UL BWP#2a may be associated with each other.

In the example shown in FIG. 5, the UE receives an indication regarding DL/UL BWP adaptation. The UE performs, for example, DL/UL BWP switching based on the instruction. For example, the UE performs switching between DL/UL BWP#1 and DL/UL BWP#1a and switching between DL/UL BWP#2 and DL/UL BWP#2a based on the instruction.

Also, in the example shown in FIG. 5, the UE receives information instructing switching between DL/UL BWP#1 and DL/UL BWP#2. In the present disclosure, existing BWP switching and DL/UL BWP switching in normal DL/UL BWP and XDD may be combined. The switching combination may be performed using a common RRC information element/MAC CE/DCI, or may be performed using different RRC information elements/MAC CE/DCI.

In addition, in the examples shown in FIGS. 4A, 4B, and 5 above, an example in which the UL BWP bandwidth is narrower (smaller) than the DL BWP bandwidth is described. The bandwidth may be equal to that of the UL BWP, or the bandwidth of the DL BWP may be narrower than the bandwidth of the UL BWP. For example, a configuration in which the UL BWP bandwidth is narrower than the DL BWP bandwidth is suitable for application in terms of UL coverage and DL communication capacity.

<<Embodiment 1-4>>
UE capabilities may be specified to support DL BWP setup and/or adaptation in XDD operation. The UE capability may be a UE capability common to or different from the UE capability for supporting at least one of UL BWP configuration and adaptation in XDD operation.

The UE capability may be different from the UE capability for operation on multiple BWPs. The UE capability may also be a capability supported by a UE that supports UE capabilities for operation with respect to multiple BWPs.

In addition, the UE capability is per UE / per band / per band in multiple band units / per feature set (FS) (per band in multiple band combination units) / per cell in FS units (multiple band combination units may be reported to the network on a per CC per band basis.

When a DL BWP in XDD is configured/activated for a specific period (e.g., slot/symbol), the UE assigns a frequency domain resource allocation (FDRA) in that specific period to the corresponding normal DL BWP and may be interpreted similarly. That is, the PRB indices (numbering/ordering) assigned to the normal DL BWP and the DL BWP in XDD may be the same. At this time, the UE may assume that DL channels/signals are not assigned by the FDRA for PRBs that are not available. Alternatively, even if a DL channel/signal is assigned by the FDRA for a PRB that is not available, the UE may not perform reception processing of the assigned portion of the DL channel/signal.

Also, when the DL BWP in XDD is configured/activated for a specific period, the UE may interpret the FDRA in that specific period differently than the corresponding normal DL BWP. That is, the (numbering/ordering of) PRB indices assigned to normal DL BWPs and DL BWPs in XDD may differ. For PRBs in DL BWP in XDD that are not available compared to the corresponding normal DL BWP, the PRB indices may not be numbered/ordered. At this time, the DL BWP PRBs in XDD may be referred to as virtually continuous PRBs.

Although the explanation above is limited to PRB, resources are not limited to this.

If at least some of the DL channels/signals are configured/scheduled outside the DL BWP in the configured/activated XDD, the UE does not expect to receive such DL channels/signals. good.

Also, if at least some of the DL channels/signals are configured/scheduled outside the DL BWP in the XDD that is configured/activated, the UE is configured/scheduled outside the DL BWP. It may not be assumed (expected) to receive at least part of it. The UE may then puncture/rate match the DL channel/signal. The puncturing/rate matching may be performed based on the specification, or may be configured/notified by higher layer signaling (RRC signaling).

In the present disclosure, transmission/reception (for example, repeated transmission/ The UE may not assume (expect) that reception (repetition, semi-persistent scheduling (SPS)) is scheduled/configured/activated.

In addition, in the present disclosure, transmission and reception across at least one of the boundaries between the normal DL/UL BWP and the DL/UL BWP in XDD, the boundary where DL/UL BWP switching is performed, and the slot boundary are scheduled/configured/activated. If so, the UE may cancel the transmission/reception. The UE may decide to cancel based on the timing of the boundary (i.e. cancel part of the transmission/reception) or independently of the timing of the boundary (i.e. cancel the entire transmission/reception). You may

According to the first embodiment, it is possible to appropriately set the DL BWP in the XDD operation.

<Second embodiment>
In the second embodiment, XDD UL frequency resources will be described.

<<Embodiment 2-1>>
[Embodiment 2-1-1]
In embodiment 2-1, in XDD operation, UL BWP (new UL BWP, UL BWP for XDD) may be set using continuous or discontinuous PRBs. The UE may be configured with UL BWP with contiguous or non-contiguous PRBs in XDD operation.

As described in Embodiment 1-1-1 above, in the frequency domain of one CC as shown in FIG. As explained, the placement/allocation of DL/UL resources is not limited to this example. One DL resource may be allocated so as to be sandwiched between two UL resources. Allocating one UL resource in the frequency domain of one CC may mean that a UL BWP using continuous PRBs is configured. Conversely, the allocation of two UL resources in the frequency domain of one CC may mean that the UL BWP using non-contiguous PRBs is configured. For example, by allocating two UL resources in the frequency domain of one CC, frequency hopping of UL transmission can be preferably applied.

At this time, the UE may recognize that the UL BWP in XDD and the normal UL BWP have different configurations. Also, the UE may switch between UL BWPs normally without dynamic indication/switching delays for UL BWPs.

Regarding UL BWP PRB settings, the UE uses total frequency resources (continuous frequency resources including frequency resources that can be used for UL and frequency resources that cannot be used for UL) and frequency resources that cannot be used for UL resources (start location/bandwidth) may be set. The total frequency resource may be configured using existing BWP parameters, such as the starting PRB (position) and the number of PRBs (bandwidth). Frequency resources that cannot be used for UL resources may be configured using, for example, the starting PRB (position) and the number of PRBs (bandwidth).

Also, regarding the setting of the UL BWP PRB, the UE may be set with available frequency resources (starting position/bandwidth). Frequency resources that cannot be used for UL resources may be configured, for example, using multiple (eg, two) sets of starting PRBs (positions) and the number of PRBs (bandwidth).

[Embodiment 2-1-2]
The configuration of the new UL BWP may be configured as a UL BWP supplementary to the normal UL BWP. Auxiliary UL BWP may be associated with the normal UL BWP. A supplemental UL BWP may be called a supplemental UL BWP, an additional UL BWP, and so on.

Setting limits may be defined for the normal UL BWP and the supplemental UL BWP. For example, even if at least one of the center frequency, subcarrier spacing, subset of frequency resources (start position/bandwidth), and settings related to UL BWP settings are common between normal UL BWP and supplemental UL BWP good. Settings related to UL BWP settings are, for example, PUCCH settings (PDCCH Config), PUSCH settings (PDSCH Config), configured grant settings (Configured grant config), SRS settings (SRS Config), radio link monitoring (RLM) settings ( RLM Config), may be at least one. Also, for example, for normal UL BWP and supplemental DL BWP, at least one of the center frequency, subcarrier spacing, subset of frequency resources (start position/bandwidth), and settings related to BWP settings are set separately. may

The association between new UL BWPs (auxiliary UL BWPs) and regular UL BWPs may be configured in a specific number ratio. The new UL BWP (auxiliary UL BWP) and the normal UL BWP may be associated 1:1, 1:N (N is an integer of 2 or more), or N:1 or N:M (M may be an integer equal to or greater than 2, and N=M).

Also, the setting of a new UL BWP may be performed by setting a UL BWP that is not normally associated with a UL BWP.

[Embodiment 2-1-3]
The UL BWP configuration may be done in conjunction with a DL BWP (new DL BWP, DL BWP for XDD, paired DL BWP) that consists of PRBs that are not allocated for the UL BWP.

Also, the setting of the new UL BWP may be performed together with at least one of the setting of the DL BWP in XDD and the setting of the normal DL BWP.

Also, the setting of the new UL BWP may not be associated with the setting of the new DL BWP. In other words, setting the new UL BWP and setting the new DL BWP may be performed separately.

Note that there may be the same restrictions between the UL BWP settings for XDD and the related DL BWP settings as between the normal UL BWP settings and the normal DL BWP settings. Also, there may be different restrictions between the UL BWP settings for XDD and the associated DL BWP settings than between the normal UL BWP settings and the normal DL BWP settings. For example, the limitation may be that the center frequencies are different between the UL BWP setting for XDD and the associated DL BWP setting. The restriction may also be that the PRBs in the UL BWP settings for XDD and the associated DL BWP settings do not overlap in the frequency domain.

<<Embodiment 2-2>>
In embodiment 2-2, semi-static configuration of UL BWP switching patterns in the time domain may be supported.

According to the switching pattern, the switching between pure UL resources (UL resources in which all frequencies in the UL resources are available for UL/UL BWP) and UL resources in XDD (new UL BWP) is activated. This can be done without the typical BWP switch indication and the delay time required for existing switching.

[Embodiment 2-2-1]
The UL BWP switching pattern may be done based on the TDD setting.

The UE may determine/judgment the DL BWP switching pattern based on the RRC information element regarding the TDD configuration (eg, TDD-UL-DL-Config). For example, the UL BWP switching pattern may be included in the RRC information element for TDD configuration (eg, TDD-UL-DL-Config).

Also, the UE may determine/judgment the UL BWP switching pattern based on the RRC information element (for example, BWP-Config) regarding the BWP configuration. For example, the UL BWP switching pattern may be included in an RRC information element regarding BWP configuration (eg, BWP-Config).

For example, the RRC information element for BWP configuration (eg, BWP-Config) may include the period and (time) offset of the UL resource in XDD. The period and offset may be expressed in a specific time unit (eg, slot, symbol), or may be expressed in arbitrary time.

Also, the UE may determine/judgment the UL BWP switching pattern based on the RRC information element regarding the BWP configuration in XDD. The RRC control element is Rel. 17 or later, or RRC information elements related to existing TDD settings (e.g., TDD-UL-DL-Config) and RRC information elements related to BWP settings (e.g., BWP-Config) may be a parameter of

[Embodiment 2-2-2]
Restrictions on the configuration of UL BWP switching patterns may be specified.

Restrictions on the time domain location of XDD UL resources may be defined. For example, UL resources in XDD may be restricted to be set temporally after normal UL resources and/or temporally before normal DL resources.

Also, for example, UL resources in XDD may be restricted so that they are set only to specific resources. The specific resource may be, for example, a resource (eg, slot) to which the UL and DL are assigned. Also, the specific resource may be, for example, a resource (for example, a slot) in which the remainder other than the UL resource in XDD is a normal UL resource (symbol). Also, the specific resource may be, for example, a slot that does not include an SS/PBCH block.

For example, UL resources in XDD may be restricted to be set temporally before normal UL resources and/or temporally after normal DL resources.

DL/UL BWP setting and BWP switching in XDD are the same as those described in Embodiment 1-2-2.

<<Embodiment 2-3>>
In embodiments 2-3, dynamic adaptation of UL BWP between pure UL resources and UL resources in XDD may be supported.

The UE determines/determines to perform dynamic adaptation of UL BWP between pure UL resources and UL resources in XDD based on at least one of DCI, MAC CE, and specific conditions. good too.

Dynamic adaptation of UL BWP for XDD may mean switching between normal UL BWP and UL BWP in XDD.

Dynamic adaptation of UL BWP for XDD may mean activation/deactivation of UL BWP in XDD associated with normal UL BWP.

The UE may apply the UL BWP adaptation only for a specific period after receiving the UL BWP adaptation instruction (Embodiment 2-3-1). The particular time period may be one or more slots/symbols. The particular time period may be indicated by an offset from the slot/symbol in which the indication is transmitted/received. The particular time period may be indicated by a particular number of slots/symbols. The specific period/offset may be predefined in the specification, configured/notified in higher layer signaling, or dynamically indicated in DCI.

In addition, the UE may apply UL BWP adaptation until receiving the next UL BWP adaptation instruction after receiving the UL BWP adaptation instruction (Embodiment 2-3-2). In other words, after receiving an indication for UL BWP adaptation, the UE may apply UL BWP adaptation until receiving an indication to cancel/override the indication.

Also, after receiving an instruction regarding UL BWP adaptation, the UE may apply UL BWP adaptation until a specific condition is met (Embodiment 2-3-3). The particular condition may be, for example, expiration of a particular timer.

At least two of the methods described in Embodiments 2-3-1 to 2-3-3 above may be applied in combination.

<<Embodiment 2-4>>
UE capabilities may be specified to support UL BWP configuration and/or adaptation in XDD operation. The UE capability may be a UE capability common to or different from the UE capability for supporting at least one of DL BWP configuration and adaptation in XDD operation.

In addition, the UE capability is per UE / per band / per feature set (FS) (per band in multiple band units) / per cell in feature set (FS) units (CC per band in multiple band combination units per)/to the network.

When the UL BWP in XDD is configured/activated for a specific period (e.g. slot/symbol), the UE assigns the Frequency Domain Resource Allocation (FDRA) in that specific period to the corresponding normal UL BWP may be interpreted similarly. That is, the (numbering/ordering of) PRB indices assigned to the normal UL BWP and the UL BWP in XDD may be the same. The UE may then assume that UL channels/signals are not scheduled by the FDRA for PRBs that are not available. Alternatively, the UE may not process the scheduled part of the UL channel/signal for transmission even if the UL channel/signal is scheduled by the FDRA for PRBs that are not available.

Also, when the UL BWP in XDD is configured/activated for a specific period, the UE may interpret the FDRA in that specific period differently than the corresponding normal UL BWP. That is, the (numbering/ordering of) PRB indices assigned to the normal UL BWP and the UL BWP in XDD may be different. For the PRBs in the UL BWP in XDD that are not available compared to the corresponding normal UL BWP, the PRB indices may not be numbered/ordered. At this time, the UL BWP PRB in XDD may be called a virtually continuous PRB.

If at least part of a UL channel/signal is configured/scheduled outside the UL BWP in the configured/activated XDD, the UE may decide not to transmit that UL channel/signal. The UE may not assume (expect) that at least some of the UL channels/signals are configured/scheduled outside the UL BWP in the configured/activated XDD.

Also, if at least some of the UL channels/signals are configured/scheduled outside the UL BWP in the XDD that is configured/activated, the UE is configured/scheduled outside the UL BWP. It may be determined not to transmit at least a portion. The UE may then puncture/rate match the UL channels/signals. The puncturing/rate matching may be performed based on the specification, or may be configured/notified by higher layer signaling (RRC signaling).

According to the second embodiment described above, it is possible to appropriately set the UL BWP in the XDD operation.

<Third Embodiment>
"analysis"
In order to realize XDD operation, the existing configuration/instruction on the slot format has different link directions (DL ('D')/UL ('U')/flexible ('F')) for different UEs. ) may be used to indicate the slot of

In the examples of FIGS. 6A and 6B, first, the link direction 'DDFFU' is set by RRC for slots #0 to #4 of UE #1 and #2, respectively.

Then, in the example of FIG. 6A, the DCI for UE #1 indicates two 'F's in slots #2 and #3 as two 'D's. This allows UE#1 to receive DL in slots #2 and #3.

To achieve XDD operation in slots #2 and #3, the base station may schedule UE #1 without PDSCH reception on some resource #1 in slots #2 and #3. Conceivable. If there is no explicit indication of unavailability of resource #1 and there can be periodic/semi-persistent SSB/CSI-RS on resource #1, there may be problems with SSB/CSI-RS measurement. There is

In the example of FIG. 6B, the DCI for UE #2 indicates two 'F's in slots #2 and #3 as two 'U's. This allows UE#2 to transmit UL in slots #2 and #3.

In order to achieve XDD operation in slots #2 and #3, the base station may schedule UE #2 without PUSCH transmission on some resource #2 in slots #2 and #3. Conceivable. If there is no explicit indication of unavailability of resource #2 and normal PUCCH/SRS resource configuration on resource #2 is not limited to resource #1, there may be problems with PUSCH/SRS/PRACH transmission. There is

Different link directions of time resources (subframes/slots/minislots/symbols) may be indicated for different UEs.

Some periodic/semi-persistent RSs may be considered to enable XDD operation on time resources designated 'D' for some UEs.

Some UL channel/RS configurations may be considered to enable XDD operation on time resources designated 'U' for some UEs.

In the present disclosure, partial availability, partially available indication, partial non-available indication, partially available DL frequency resource, partial utilization A combination of available UL frequency resources, partially unavailable DL frequency resources, partially unavailable UL frequency resources, link direction (D/F/U) and partial availability may be read interchangeably.

<<Embodiment 3-1>>
Based on the existing link direction (D/F/U) indication, a new type of indication (new indication) may be defined to indicate "partial availability" for a time unit. In this disclosure, a time unit may be a time resource with a certain length, eg, subframe/slot/minislot/symbol. In this disclosure, the partial availability indication may indicate whether some frequency resources (resource blocks/resource elements) within a component carrier/BWP are available for a particular link direction. Alternatively, the frequency resource may be indicated.

The new indication may be RRC IE/MAC CE/DCI.

The new indication may be signaling different from the signaling of the existing link direction indication. In other words, the RRC IE/MAC CE/DCI elements of the new indication (e.g. partial availability indication, partial frequency resource indication, etc.) are replaced with the existing link direction indication (e.g. D/F/U indication). ) may be separated from the RRC IE/MAC CE/DCI elements.

The new indication may be signaling combined with existing link direction indication signaling. In other words, a combination of existing link direction indications and new indications (e.g., partial availability and D/F/U indications, D/F/U/partially available D/partially available U indication) may be notified of RRC IE/MAC CE/DCI.

The UE provides a 'partial available indication' (partial frequency resources available) and an indication of 'D' (time unit for DL) (indication of partial frequency resources available for DL, partial available DL frequency resource) and 'partial non-available indication' (partial frequency resource unavailable) and 'D' (time unit for DL) indication (DL indication of partial unavailable frequency resources, indication of partial unavailable DL frequency resources).

The UE shall provide a 'partial availability indication' (partial frequency resource available) and an indication of 'U' (time unit for UL) (indication of partial frequency resource available for UL, partial available UL frequency resource) and a 'partial unavailability indication' (partial frequency resource unavailable) and an indication 'U' (time unit for UL) (an indication of partial frequency resource unavailable for UL, indication of partially unavailable UL frequency resources).

The UE sends a 'partial availability indication' (partial frequency resource available) and 'D' (time unit for DL) indication (partial available DL frequency resource indication) and a 'partial availability indication ' (partial frequency resource available) and an indication of 'U' (time unit for UL) (indication of partial available UL frequency resource). Based on the indication of the partial available DL frequency resources in a time unit, the UE may select partial unavailable DL frequency resources in the time unit (partially available DL frequency resources in the time unit). (partial frequency resources other than ) may be identified. Based on the indication of the partial available UL frequency resources in a time unit, the UE may select partial unavailable DL frequency resources in the time unit (partially available UL frequency resources in the time unit). (partial frequency resources other than ) may be identified.

The UE shall give a 'partially unavailable indication' (partially unavailable frequency resource) and 'D' (time unit for DL) indication (an indication of partially unavailable DL frequency resource) and a 'partially 'unavailable indication' (partial frequency resource unavailable) and 'U' (time unit for UL) indication (partially unavailable DL frequency resource indication). good. Based on the indication of the partially unavailable DL frequency resources in a time unit, the UE may select the partially available DL frequency resources in the time unit (partially unavailable DL frequency in the time unit). (partial frequency resources other than resources) may be identified. Based on the indication of the partially unavailable UL frequency resources in a time unit, the UE may select the partially available UL frequency resources in the time unit (partially unavailable UL frequency resources in the time unit). (partial frequency resources other than resources) may be identified.

If a time unit is indicated with a 'partially available indication' and 'D' (indicated with a partially available DL frequency resource), the UE shall It may be assumed to receive DL channels/RS on frequency resources, or it may not be assumed to receive DL channels/RS on partially unavailable DL frequency resources within that time unit. If a time unit is indicated with 'partially unavailable indication' and 'D' (indicated with a partially unavailable DL frequency resource), the UE may use a partial utilization within that time unit. It may be assumed to receive DL channels/RS on available DL frequency resources, or it may not be assumed to receive DL channels/RS on partially unavailable DL frequency resources within that time unit. good.

If a time unit is indicated with a 'partially unavailable indication' and 'U' (indicated a partially unavailable UL frequency resource), the UE may use a partial utilization within that time unit. It may be assumed to receive DL channels/RS on impossible UL frequency resources, or it may not be assumed to receive DL channels/RS on partial available UL frequency resources within that time unit. good.

The partially available DL frequency resource (P_AD) can be set/indicated by the RRC IE/MAC CE. For example, setting/indicating that partially available DL frequency resources may disable some frequency resources (partially unavailable DL frequency resources (P_ND)) (FIG. 7A), The two sets may be combined (Fig. 7B).

A common partial available DL frequency resource may be configured/indicated for multiple time units (eg, time units #0 and #1) (FIG. 7A). Different partial available DL frequency resources may be configured/indicated for multiple time units (eg, time units #0 and #1) (FIG. 7B).

If a time unit is indicated with a 'partially available indication' and 'U' (indicated with a partially available UL frequency resource), the UE shall It may be assumed that the UL channel/RS is transmitted on a frequency resource, or it may not be assumed that the UL channel/RS is transmitted on a partially unavailable UL frequency resource within that time unit. If a time unit is indicated with a 'partially unavailable indication' and 'U' (indicated a partially unavailable UL frequency resource), the UE may use a partial utilization within that time unit. It may be assumed that the UL channels/RS are transmitted on available UL frequency resources, or it is not assumed that the UL channels/RS are transmitted on partially unavailable UL frequency resources within the time unit. good.

If a time unit is indicated with 'partially unavailable indication' and 'D' (indicated with a partially unavailable DL frequency resource), the UE may use a partial utilization within that time unit. It may be assumed that UL channels/RS are transmitted on impossible DL frequency resources, or it is not assumed that UL channels/RS are transmitted on partial available DL frequency resources within that time unit. good.

The partially available UL frequency resource (P_AU) can be set/indicated by the RRC IE/MAC CE. For example, setting/indicating that partially available UL frequency resources may disable some frequency resources (partially unavailable UL frequency resources (P_NU)) (FIG. 7C), The two sets may be combined (Fig. 7D).

A common partial available UL frequency resource may be configured/indicated for multiple time units (eg, time units #0 and #1) (FIG. 7C). Different partial available UL frequency resources may be configured/indicated for multiple time units (eg, time units #0 and #1) (FIG. 7D).

According to this embodiment, the link direction can be set/indicated for each time resource, and the partially available or unavailable frequency resource can be flexibly set/indicated.

<<Embodiment 3-2>>
Here, UE operation in partially available DL time units is described. Partially available DL time units are indicated by 'partially available indication' and 'D' (partially available DL frequency resource, P_AD), or by 'partially unavailable indication' and 'U' (partially available Impossible UL frequency resource, P_UL).

- PDSCH reception A UE may assume that PDSCH reception is scheduled only on partially available DL frequency resources (or partially unavailable UL frequency resources) within partially available DL time units. The UE may perform rate matching around the partially unavailable DL frequency resource (or the partially available UL frequency resource) within the partially available DL time unit.

[Option 1]
Frequency resource configuration and frequency domain resource allocation (frequency domain resource assignment (FDMA) indication in DCI) for normal DL time units (time units not indicated with partial availability indication and indicated 'D') time units , and partially available DL time units are common (consistent). The UE may not assume that the FDRA indication places PDSCH resources that overlap with partially unavailable DL frequency resources (or partially available UL frequency resources) within partially available DL time units. It may be an error case if the FDRA field places a PDSCH resource that overlaps with a partially unavailable DL frequency resource within a partially available DL time unit.

[Option 2]
Frequency resource configuration and mapping to frequency domain resource allocation (FDMA indication in DCI) for normal DL time units (time units not indicated with partial available indication and indicated 'D') and partial utilization possible DL time units are common (consistent). The UE may perform rate matching around the partially unavailable DL frequency resource (or the partially available UL frequency resource) within the partially available DL time unit. If the FDRA indication includes a partially unavailable DL frequency resource within the partially available DL time unit, the UE may rate match around the partially unavailable DL frequency resource.

[Option 3]
The frequency resource configuration and mapping to frequency domain resource allocation (FDMA indication in DCI) for partial available DL time units is configured separately by RRC IE. The UE may interpret the FDRA on the partially available DL frequency resource within the partially available DL time unit based on the new configuration.

For DMRS and phase tracking reference signal (PTRS), the UE may handle it similarly to PDSCH.

[Option 2]
If SSB can be transmitted in a certain time unit according to the SSB period, the UE does not assume that the time unit is indicated with a partially available DL frequency resource.

[Option 2]
A UE is sent aperiodic CSI-RS on a partially unavailable DL frequency resource within a partially available DL time unit (partially unavailable within a partially available DL time unit). It is not assumed that aperiodic CSI-RS transmitted on DL frequency resources are scheduled (triggered) by DCI.

- DL-PRS measurement The UE does not monitor DL-positioning reference signals (PRS) on partially unavailable DL frequency resources (or partially available UL frequency resources) within partially available DL time units. The UE may follow either of

Options

1 and 2 below.

[Option 1]
If the DL-PRS can be transmitted according to the periodicity on the partially unavailable DL frequency resource within the partially available DL time unit, the UE may transmit the DL-PRS on the partially unavailable DL frequency resource. Ignore (do not make) PRS measurements.

[Option 2]
If the DL-PRS can be transmitted periodically in a certain time unit, the UE does not assume that the time unit is indicated with a partially available DL frequency resource.

According to this embodiment, for each time resource, the UE can control reception appropriately in time resources indicated for DL and partial availability.

<<Embodiment 3-3>>
UE operation in partially available UL time units is described herein. Partially available UL time units are defined as 'partially available indication' and 'U' (partially available UL frequency resource, P_AU) or 'partially unavailable indication' and 'D' (partially available Impossible DL frequency resource, P_ND).

- PUCCH configuration For PUCCH configuration for partially available UL time units, the UE may follow at least one of

options

1 and 2 below.

[Option 1]
Another PUCCH configuration may be configured for the partially available UL time unit. PUCCH configuration for partial availability UL time units may be configured separately from PUCCH configuration for normal UL time units (time units not indicated with partial availability indication and indicated with 'U').

[Option 2]
A single PUCCH configuration is configured with some PUCCH resources for normal UL time units and some PUCCH resources for partially available UL time units. The UE may select PUCCH resources corresponding to time resources.

For PUCCH applications, the UE may follow either of

[Option 2]
For partial available UL time units, PUCCH usage is restricted to HARQ-ACK feedback only (HARQ-ACK with SR or HARQ-ACK without SR).

The settings for transmit power control (TPC) for partially available UL time units may differ from the settings for TPC for normal UL time units.

The UE may handle DMRS in the same way as PUCCH.

[Option 2]
A separate PUSCH configuration for the partially available UL time unit (a PUSCH configuration separate from the PUSCH configuration for the normal UL time unit) is not configured. In this case, the UE may not assume that PUSCH transmissions on partially unavailable UL frequency resources are scheduled.

The setting for TPC for partially available UL time units may differ from the setting for TPC for normal UL time units. DMRS and PTRS may be handled by the UE in the same way as PUSCH.

- PRACH configuration For PRACH configuration for partially available UL time units, the UE may follow at least one of

options

1 and 2 below.

[Option 1]
A separate PRACH configuration (a different PRACH configuration than for normal UL time units) is configured for the partially available UL time units.

(Modification)
The terms explained in this disclosure and the terms necessary for understanding the present disclosure may be replaced with terms having the same or similar meanings. For example, channel, symbol and signal (signal or signaling) may be interchanged. A signal may also be a message. A reference signal may be abbreviated as RS, and may also be called a pilot, a pilot signal, etc., depending on the applicable standard. A component carrier (CC) may also be called a cell, a frequency carrier, a carrier frequency, or the like.

A radio frame may consist of one or more periods (frames) in the time domain. Each of the one or more periods (frames) that make up a radio frame may be called a subframe. Furthermore, a subframe may consist of one or more slots in the time domain. A subframe may be a fixed time length (eg, 1 ms) independent of numerology.

Here, a numerology may be a communication parameter applied to at least one of transmission and reception of a certain signal or channel. Numerology, for example, subcarrier spacing (SCS), bandwidth, symbol length, cyclic prefix length, transmission time interval (TTI), number of symbols per TTI, radio frame configuration , a particular filtering process performed by the transceiver in the frequency domain, a particular windowing process performed by the transceiver in the time domain, and/or the like.

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

A slot may contain multiple mini-slots. Each minislot may consist of one or more symbols in the time domain. A minislot may also be referred to as a subslot. A minislot may consist of fewer symbols than a slot. A PDSCH (or PUSCH) transmitted in time units larger than a minislot may be referred to as PDSCH (PUSCH) Mapping Type A. PDSCH (or PUSCH) transmitted using minislots may be referred to as PDSCH (PUSCH) mapping type B.

Radio frames, subframes, slots, minislots and symbols all represent time units when transmitting signals. Radio frames, subframes, slots, minislots and symbols may be referred to by other corresponding designations. Note that time units such as frames, subframes, slots, minislots, and symbols in the present disclosure may be read interchangeably.

For example, one subframe may be called a TTI, a plurality of consecutive subframes may be called a TTI, and one slot or one minislot may be called a TTI. That is, at least one of the subframe and TTI may be a subframe (1 ms) in existing LTE, a period shorter than 1 ms (eg, 1-13 symbols), or a period longer than 1 ms may be Note that the unit representing the TTI may be called a slot, mini-slot, or the like instead of a subframe.

Here, TTI refers to, for example, the minimum scheduling time unit in wireless communication. For example, in the LTE system, a base station performs scheduling to allocate radio resources (frequency bandwidth, transmission power, etc. that can be used by each user terminal) to each user terminal on a TTI basis. Note that the definition of TTI is not limited to this.

A TTI may be a transmission time unit such as a channel-encoded data packet (transport block), code block, or codeword, or may be a processing unit such as scheduling and link adaptation. Note that when a TTI is given, the time interval (for example, the number of symbols) in which transport blocks, code blocks, codewords, etc. are actually mapped may be shorter than the TTI.

When one slot or one minislot is called a TTI, one or more TTIs (that is, one or more slots or one or more minislots) may be the minimum scheduling time unit. Also, the number of slots (the number of mini-slots) constituting the minimum time unit of the scheduling may be controlled.

A TTI having a time length of 1 ms may be called a normal TTI (TTI in 3GPP Rel. 8-12), normal TTI, long TTI, normal subframe, normal subframe, long subframe, slot, or the like. A TTI that is shorter than a normal TTI may be called a shortened TTI, a short TTI, a partial or fractional TTI, a shortened subframe, a short subframe, a minislot, a subslot, a slot, and the like.

Note that the long TTI (e.g., normal TTI, subframe, etc.) may be replaced with a TTI having a time length exceeding 1 ms, and the short TTI (e.g., shortened TTI, etc.) is less than the TTI length of the long TTI and 1 ms A TTI having the above TTI length may be read instead.

A resource block (RB) is a resource allocation unit in the time domain and frequency domain, and may include one or more consecutive subcarriers (subcarriers) in the frequency domain. The number of subcarriers included in the RB may be the same regardless of the neumerology, eg twelve. The number of subcarriers included in an RB may be determined based on neumerology.

Also, an RB may contain one or more symbols in the time domain and may be 1 slot, 1 minislot, 1 subframe or 1 TTI long. One TTI, one subframe, etc. may each be configured with one or more resource blocks.

One or more RBs are Physical Resource Block (PRB), Sub-Carrier Group (SCG), Resource Element Group (REG), PRB pair, RB Also called a pair.

Also, a resource block may be composed of one or more resource elements (Resource Element (RE)). For example, 1 RE may be a radio resource region of 1 subcarrier and 1 symbol.

A Bandwidth Part (BWP) (which may also be called a bandwidth part) represents a subset of contiguous common resource blocks (RBs) for a numerology on a carrier. good too. Here, the common RB may be identified by an RB index based on the common reference point of the carrier. PRBs may be defined in a BWP and numbered within that BWP.

BWP may include UL BWP (BWP for UL) and DL BWP (BWP for DL). One or multiple BWPs may be configured for a UE within one carrier.

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 "cell", "carrier", etc. in the present disclosure may be read as "BWP".

It should be noted that the structures of radio frames, subframes, slots, minislots, symbols, etc. described above are merely examples. For example, the number of subframes contained in a radio frame, the number of slots per subframe or radio frame, the number of minislots contained within a slot, the number of symbols and RBs contained in a slot or minislot, the number of Configurations such as the number of subcarriers and the number of symbols in a TTI, symbol length, cyclic prefix (CP) length, etc. can be varied.
