Title: Method for applying msd and apparatus thereof

Description:
BACKGROUND 
     3rd generation partnership project (3GPP) long-term evolution (LTE) is a technology for enabling high-speed packet communications. Many schemes have been proposed for the LTE objective including those that aim to reduce user and provider costs, improve service quality, and expand and improve coverage and system capacity. The 3GPP LTE requires reduced cost per bit, increased service availability, flexible use of a frequency band, a simple structure, an open interface, and adequate power consumption of a terminal as an upper-level requirement. 
     Work has started in international telecommunication union (ITU) and 3GPP to develop requirements and specifications for new radio (NR) systems. 3GPP has to identify and develop the technology components needed for successfully standardizing the new RAT timely satisfying both the urgent market needs, and the more long-term requirements set forth by the ITU radio communication sector (ITU-R) international mobile telecommunications (IMT)-2020 process. Further, the NR should be able to use any spectrum band ranging at least up to 100 GHz that may be made available for wireless communications even in a more distant future. 
     The NR targets a single technical framework addressing all usage scenarios, requirements and deployment scenarios including enhanced mobile broadband (eMBB), massive machine-type-communications (mMTC), ultra-reliable and low latency communications (URLLC), etc. The NR shall be inherently forward compatible. A mobile device should be configured to satisfy a reference sensitivity power level (REFSENS) which is the minimum average power for each antenna port of the mobile device when receiving the downlink signal. 
     When a harmonics component and/or an intermodulation distortion (IMD) component occurs, there is a possibility that the REFSENS for the downlink signal may not be satisfied due to the uplink signal transmitted by the mobile device. 
     When a harmonics component and/or an intermodulation distortion (IMD) component occurs, there is a possibility that the REFSENS for the downlink signal may not be satisfied due to the uplink signal transmitted by the mobile device. 
     SUMMARY

UTRA is a part of a universal mobile telecommunications system (UMTS). 3rd generation partnership project (3GPP) long term evolution (LTE) is a part of evolved UMTS (E-UMTS) using E-UTRA. 3GPP LTE employs OFDMA in DL and SC-FDMA in UL. Evolution of 3GPP LTE includes LTE-A (advanced), LTE-A Pro, and/or 5G NR (new radio). 
     For convenience of description, implementations of the present disclosure are mainly described in regards to a 3GPP based wireless communication system. However, the technical features of the present disclosure are not limited thereto. For example, although the following detailed description is given based on a mobile communication system corresponding to a 3GPP based wireless communication system, aspects of the present disclosure that are not limited to 3GPP based wireless communication system are applicable to other mobile communication systems. 
     For terms and technologies which are not specifically described among the terms of and technologies employed in the present disclosure, the wireless communication standard documents published before the present disclosure may be referenced.

     Although not limited thereto, various descriptions, functions, procedures, suggestions, methods and/or operational flowcharts of the present disclosure disclosed herein can be applied to various fields requiring wireless communication and/or connection (e.g., 5G) between devices. 
     Hereinafter, the present disclosure will be described in more detail with reference to drawings. The same reference numerals in the following drawings and/or descriptions may refer to the same and/or corresponding hardware blocks, software blocks, and/or functional blocks unless otherwise indicated. 
       FIG.  1    shows an example of a communication system to which implementations of the present disclosure is applied. 
     The 5G usage scenarios shown in  FIG.  1    are only exemplary, and the technical features of the present disclosure can be applied to other 5G usage scenarios which are not shown in  FIG.  1   . 
     Three main requirement categories for 5G include (1) a category of enhanced mobile broadband (eMBB), (2) a category of massive machine type communication (mMTC), and (3) a category of ultra-reliable and low latency communications (URLLC). 
     Referring to  FIG.  1   , the communication system  1  includes wireless devices  100   a  to  100   f , base stations (BSs)  200 , and a network  300 . Although  FIG.  1    illustrates a 5G network as an example of the network of the communication system  1 , the implementations of the present disclosure are not limited to the 5G system, and can be applied to the future communication system beyond the 5G system. 
     The BSs  200  and the network  300  may be implemented as wireless devices and a specific wireless device may operate as a BS/network node with respect to other wireless devices. 
     The wireless devices  100   a  to  100   f  represent devices performing communication using radio access technology (RAT) (e.g., 5G new RAT (NR)) or LTE) and may be referred to as communication/radio/5G devices. The wireless devices  100   a  to  100   f  may include, without being limited to, a robot  100   a , vehicles  100   b - 1  and  100   b - 2 , an extended reality (XR) device  100   c , a hand-held device  100   d , a home appliance  100   e , an IoT device  100   f , and an artificial intelligence (AI) device/server  400 . For example, the vehicles may include a vehicle having a wireless communication function, an autonomous driving vehicle, and a vehicle capable of performing communication between vehicles. The vehicles may include an unmanned aerial vehicle (UAV) (e.g., a drone). The XR device may include an AR/VR/Mixed Reality (MR) device and may be implemented in the form of a head-mounted device (HMD), a head-up display (HUD) mounted in a vehicle, a television, a smartphone, a computer, a wearable device, a home appliance device, a digital signage, a vehicle, a robot, etc. The hand-held device may include a smartphone, a smartpad, a wearable device (e.g., a smartwatch or a smartglasses), and a computer (e.g., a notebook). The home appliance may include a TV, a refrigerator, and a washing machine. The IoT device may include a sensor and a smartmeter. 
     In the present disclosure, the wireless devices  100   a  to  100   f  may be called user equipments (UEs). A UE may include, for example, a cellular phone, a smartphone, a laptop computer, a digital broadcast terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation system, a slate personal computer (PC), a tablet PC, an ultrabook, a vehicle, a vehicle having an autonomous traveling function, a connected car, an UAV, an AI module, a robot, an AR device, a VR device, an MR device, a hologram device, a public safety device, an MTC device, an IoT device, a medical device, a FinTech device (or a financial device), a security device, a weather/environment device, a device related to a 5G service, or a device related to a fourth industrial revolution field. 
     The wireless devices  100   a  to  100   f  may be connected to the network  300  via the BSs  200 . An AI technology may be applied to the wireless devices  100   a  to  100   f  and the wireless devices  100   a  to  100   f  may be connected to the AI server  400  via the network  300 . The network  300  may be configured using a 3G network, a 4G (e.g., LTE) network, a 5G (e.g., NR) network, and a beyond-5G network. Although the wireless devices  100   a  to  100   f  may communicate with each other through the BSs  200 /network  300 , the wireless devices  100   a  to  100   f  may perform direct communication (e.g., sidelink communication) with each other without passing through the BSs  200 /network  300 . For example, the vehicles  100   b - 1  and  100   b - 2  may perform direct communication (e.g., vehicle-to-vehicle (V2V)/vehicle-to-everything (V2X) communication). The IoT device (e.g., a sensor) may perform direct communication with other IoT devices (e.g., sensors) or other wireless devices  100   a  to  100   f.    
     Wireless communication/connections  150   a ,  150   b  and  150   c  may be established between the wireless devices  100   a  to  100   f  and/or between wireless device  100   a  to  100   f  and BS  200  and/or between BSs  200 . Herein, the wireless communication/connections may be established through various RATs (e.g., 5G NR) such as uplink/downlink communication  150   a , sidelink communication (or device-to-device (D2D) communication)  150   b , inter-base station communication  150   c  (e.g., relay, integrated access and backhaul (JAB)), etc. The wireless devices  100   a  to  100   f  and the BSs  200 /the wireless devices  100   a  to  100   f  may transmit/receive radio signals to/from each other through the wireless communication/connections  150   a ,  150   b  and  150   c . For example, the wireless communication/connections  150   a ,  150   b  and  150   c  may transmit/receive signals through various physical channels. To this end, at least a part of various configuration information configuring processes, various signal processing processes (e.g., channel encoding/decoding, modulation/demodulation, and resource mapping/de-mapping), and resource allocating processes, for transmitting/receiving radio signals, may be performed based on the various proposals of the present disclosure. 
     AI refers to the field of studying artificial intelligence or the methodology that can create it, and machine learning refers to the field of defining various problems addressed in the field of AI and the field of methodology to solve them. Machine learning is also defined as an algorithm that increases the performance of a task through steady experience on a task. 
     Robot means a machine that automatically processes or operates a given task by its own ability. In particular, robots with the ability to recognize the environment and make self-determination to perform actions can be called intelligent robots. Robots can be classified as industrial, medical, home, military, etc., depending on the purpose or area of use. The robot can perform a variety of physical operations, such as moving the robot joints with actuators or motors. The movable robot also includes wheels, brakes, propellers, etc., on the drive, allowing it to drive on the ground or fly in the air. 
     Autonomous driving means a technology that drives on its own, and autonomous vehicles mean vehicles that drive without user&#39;s control or with minimal user&#39;s control. For example, autonomous driving may include maintaining lanes in motion, automatically adjusting speed such as adaptive cruise control, automatic driving along a set route, and automatically setting a route when a destination is set. The vehicle covers vehicles equipped with internal combustion engines, hybrid vehicles equipped with internal combustion engines and electric motors, and electric vehicles equipped with electric motors, and may include trains, motorcycles, etc., as well as cars. Autonomous vehicles can be seen as robots with autonomous driving functions. 
     Extended reality is collectively referred to as VR, AR, and MR. VR technology provides objects and backgrounds of real world only through computer graphic (CG) images. AR technology provides a virtual CG image on top of a real object image. MR technology is a CG technology that combines and combines virtual objects into the real world. MR technology is similar to AR technology in that they show real and virtual objects together. However, there is a difference in that in AR technology, virtual objects are used as complementary forms to real objects, while in MR technology, virtual objects and real objects are used as equal personalities. 
     NR supports multiples numerologies (and/or multiple subcarrier spacings (SCS)) to support various 5G services. For example, if SCS is 15 kHz, wide area can be supported in traditional cellular bands, and if SCS is 30 kHz/60 kHz, dense-urban, lower latency, and wider carrier bandwidth can be supported. If SCS is 60 kHz or higher, bandwidths greater than 24.25 GHz can be supported to overcome phase noise. 
     The NR frequency band may be defined as two types of frequency range, i.e., FR1 and FR2. The numerical value of the frequency range may be changed. For example, the frequency ranges of the two types (FR1 and FR2) may be as shown in Table 1 below. For ease of explanation, in the frequency ranges used in the NR system, FR1 may mean “sub 6 GHz range”, FR2 may mean “above 6 GHz range,” and may be referred to as millimeter wave (mmW).

     As mentioned above, the numerical value of the frequency range of the NR system may be changed. For example, FR1 may include a frequency band of 410 MHz to 7125 MHz as shown in Table 2 below. That is, FR1 may include a frequency band of 6 GHz (or 5850, 5900, 5925 MHz, etc.) or more. For example, a frequency band of 6 GHz (or 5850, 5900, 5925 MHz, etc.) or more included in FR1 may include an unlicensed band. Unlicensed bands may be used for a variety of purposes, for example for communication for vehicles (e.g., autonomous driving).

     Here, the radio communication technologies implemented in the wireless devices in the present disclosure may include narrowband internet-of-things (NB-IoT) technology for low-power communication as well as LTE, NR and 6G. For example, NB-IoT technology may be an example of low power wide area network (LPWAN) technology, may be implemented in specifications such as LTE Cat NB 1  and/or LTE Cat NB 2 , and may not be limited to the above-mentioned names. Additionally and/or alternatively, the radio communication technologies implemented in the wireless devices in the present disclosure may communicate based on LTE-M technology. For example, LTE-M technology may be an example of LPWAN technology and be called by various names such as enhanced machine type communication (eMTC). For example, LTE-M technology may be implemented in at least one of the various specifications, such as 1) LTE Cat 0, 2) LTE Cat M1, 3) LTE Cat M2, 4) LTE non-bandwidth limited (non-BL), 5) LTE-MTC, 6) LTE Machine Type Communication, and/or 7) LTE M, and may not be limited to the above-mentioned names.

     &lt;Carrier Aggregation&gt; 
     A carrier aggregation system is now described. 
     A carrier aggregation system aggregates a plurality of component carriers (CCs). A meaning of an existing cell is changed according to the above carrier aggregation. According to the carrier aggregation, a cell may signify a combination of a downlink component carrier and an uplink component carrier or an independent downlink component carrier. 
     Further, the cell in the carrier aggregation may be classified into a primary cell, a secondary cell, and a serving cell. The primary cell signifies a cell operated in a primary frequency. The primary cell signifies a cell which UE performs an initial connection establishment procedure or a connection reestablishment procedure or a cell indicated as a primary cell in a handover procedure. The secondary cell signifies a cell operating in a secondary frequency. Once the RRC connection is established, the secondary cell is used to provide an additional radio resource. 
     As described above, the carrier aggregation system may support a plurality of component carriers (CCs), that is, a plurality of serving cells unlike a single carrier system. 
     The carrier aggregation system may support a cross-carrier scheduling. The cross-carrier scheduling is a scheduling method capable of performing resource allocation of a PDSCH transmitted through other component carrier through a PDCCH transmitted through a specific component carrier and/or resource allocation of a PUSCH transmitted through other component carrier different from a component carrier basically linked with the specific component carrier. 
     Carrier aggregation can also be classified into inter-band CA and intra-band CA. The inter-band CA is a method of aggregating and using each CC existing in different operating bands, and the intra-band CA is a method of aggregating and using each CC in the same operating band. In addition, the CA technology is more specifically, intra-band contiguous CA, intra-band non-contiguous CA and inter-band discontinuity. Non-Contiguous) CA. 
       FIG.  5   a    illustrates a concept view of an example of intra-band contiguous CA.  FIG.  5   b    illustrates a concept view of an example of intra-band non-contiguous CA. 
     The CA may be split into the intra-band contiguous CA shown in  FIG.  5   a    and the intra-band non-contiguous CA shown in  FIG.  5     b.    
       FIG.  6   a    illustrates a concept view of an example of a combination of a lower frequency band and a higher frequency band for inter-band CA.  FIG.  6   b    illustrates a concept view of an example of a combination of similar frequency bands for inter-band CA. 
     The inter-band carrier aggregation may be separated into inter-band CA between carriers of a low band and a high band having different RF characteristics of inter-band CA as shown in  FIG.  6   a    and inter-band CA of similar frequencies that may use a common RF terminal per component carrier due to similar RF (radio frequency) characteristics as shown in  FIG.  6     b.    
     For inter-band carrier aggregation, a carrier aggregation configuration is a combination of operating bands, each supporting a carrier aggregation bandwidth class. 
     &lt;Introduction of Dual Connectivity (DC)&gt; 
     Recently, a scheme for simultaneously connecting UE to different base stations, for example, a macro cell base station and a small cell base station, is being studied. This is called dual connectivity (DC). 
     In DC, the eNodeB for the primary cell (Pcell) may be referred to as a master eNodeB (hereinafter referred to as MeNB). In addition, the eNodeB only for the secondary cell (Scell) may be referred to as a secondary eNodeB (hereinafter referred to as SeNB). 
     A cell group including a primary cell (Pcell) implemented by MeNB may be referred to as a master cell group (MCG) or PUCCH cell group  1 . A cell group including a secondary cell (Scell) implemented by the SeNB may be referred to as a secondary cell group (SCG) or PUCCH cell group  2 . 
     Meanwhile, among the secondary cells in the secondary cell group (SCG), a secondary cell in which the UE can transmit Uplink Control Information (UCI), or the secondary cell in which the UE can transmit a PUCCH may be referred to as a super secondary cell (Super SCell) or a primary secondary cell (Primary Scell; PScell). 
       FIGS.  7   a  to  7   c    are exemplary diagrams illustrating exemplary architectures for services of the next generation mobile communication. 
     Referring to  FIG.  7   a   , the UE is connected to LTE/LTE-A based cells and NR based cells in a dual connectivity (DC) manner. 
     The NR-based cell is connected to a core network for existing 4G mobile communication, that is, an evolved packet core (EPC). 
     Referring to  FIG.  7   b   , unlike  FIG.  7   a   , the LTE/LTE-A based cell is connected to a core network for the 5G mobile communication, that is, a next generation (NG) core network. 
     The service scheme based on the architecture as illustrated in  FIGS.  7   a  and  7   b    is called non-standalone (NSA). 
     Referring to  FIG.  7   c   , the UE is connected only to NR-based cells. The service method based on such an architecture is called standalone (SA). 
     On the other hand, in the NR, it may be considered that the reception from the base station uses a downlink subframe, and the transmission to the base station uses an uplink subframe. This method may be applied to paired spectra and unpaired spectra. A pair of spectra means that the two carrier spectra are included for downlink and uplink operations. For example, in a pair of spectra, one carrier may include a downlink band and an uplink band that are paired with each other. 
       FIG.  8    illustrates an example of situation in which uplink signal transmitted via an uplink operating bands affects reception of a downlink signal via downlink operating bands. 
     In  FIG.  8   , an Intermodulation Distortion (IMD) may mean amplitude modulation of signals containing two or more different frequencies, caused by nonlinearities or time variance in a system. The intermodulation between frequency components will form additional components at frequencies that are not just at harmonic frequencies (integer multiples) of either, like harmonic distortion, but also at the sum and difference frequencies of the original frequencies and at sums and differences of multiples of those frequencies. 
     Referring to  FIG.  8   , an example in which a CA is configured in a terminal is shown. For example, the terminal may perform communication through the CA based on three downlink operating bands (UL Band X, Y, Z) and two uplink operating bands (DL Band X, Y). 
     As shown in  FIG.  8   , in a situation in which three downlink operating bands are configured and two uplink operating bands are configured by the CA, the terminal may transmit an uplink signal through two uplink operating bands. In this case, a harmonics component and an intermodulation distortion (IMD) component occurring based on the frequency band of the uplink signal may fall into its own downlink band. That is, in the example of  FIG.  8   , when the terminal transmits the uplink signal, the harmonics component and the intermodulation distortion (IMD) component may occur, which may affect the downlink band of the terminal itself. 
     The terminal should be configured to satisfy a reference sensitivity power level (REFSENS) which is the minimum average power for each antenna port of the terminal when receiving the downlink signal. 
     When the harmonics component and/or IMD component occur as shown in the example of  FIG.  8   , there is a possibility that the REFSENS for the downlink signal may not be satisfied due to the uplink signal transmitted by the UE itself. 
     For example, the REFSENS may be set such that the downlink signal throughput of the terminal is 95% or more of the maximum throughput of the reference measurement channel. When the harmonics component and/or IMD component occur, there is a possibility that the downlink signal throughput is reduced to 95% or less of the maximum throughput. 
     Disclosure of the Present Disclosure 
     Therefore, it is determined whether the harmonics component and the IMD component of the terminal occur, and when the harmonics component and/or IMD component occur, the maximum sensitivity degradation (MSD) value is defined for the corresponding frequency band, so relaxation for REFSENS in the reception band may be allowed in the reception band due to its own transmission signal. Here, the MSD may mean the maximum allowed reduction of the REFSENS. When the MSD is defined for a specific operating band of the terminal where the CA or DC is configured, the REFSENS of the corresponding operating band may be relaxed by the amount of the defined MSD. 
     The disclosure of the present specification provides results of analysis about self-interference in a terminal configured with CA and NR EN-DC and amount of relaxation to sensitivity. 
     I. Reference Sensitivity 
     The reference sensitivity power level REFSENS is the minimum mean power applied to each one of the UE antenna ports for all UE categories, at which the throughput shall meet or exceed the requirements for the specified reference measurement channel. 
     For EN-DC, E-UTRA and NR single carrier, CA, and MIMO operation of REFSENS requirements defined apply to all downlink bands of EN-DC configurations listed, unless sensitivity degradation exception is allowed in this clause of this specification. Allowed exceptions specified in this clause also apply to any higher order EN-DC configuration combination containing one of the band combinations that exception is allowed for. Reference sensitivity exceptions are specified by applying maximum sensitivity degradation (MSD) into applicable REFSENS requirement. EN-DC REFSENS requirements shall be met for NR uplink transmissions using QPSK DFT-s-OFDM waveforms as defined. Unless otherwise specified UL allocation uses the lowest SCS allowable for a given channel BW. Limits on configured maximum output power for the uplink shall apply. 
     In case of intra-band EN-DC the receiver REFSENS requirements in this clause do not apply for 1.4 and 3 MHz E-UTRA carriers. For the case of inter-band EN-DC with a single carrier per cell group and multi-carrier per cell group, in addition to the E-UTRA and NR single carrier, CA, and MIMO operation of REFSENS requirements defined the REFSENS requirements specified therein also apply with both downlink carriers and both uplink carriers active unless sensitivity exceptions are allowed in this clause of this specification. 
     For inter-band EN-DC, the reference sensitivity requirement with both uplink carriers active is allowed to be verified for only a single inter-band EN-DC configuration per NR band. 
     For intra-band contiguous EN-DC configurations, the reference sensitivity power level REFSENS is the minimum mean power applied to each one of the UE antenna ports at which the throughput for the carrier(s) of the E-UTRA and NR CGs shall meet or exceed the requirements for the specified E-UTRA and NR reference measurement channels. The reference sensitivity requirements apply with all uplink carriers and all downlink carriers active for EN-DC configuration and Uplink EN-DC configuration, as supported by the UE. For EN-DC configurations where uplink is not available in either the MCG or the SCG or for EN-DC configurations where the UE only supports single uplink operation, reference sensitivity requirements apply with single uplink transmission. The downlink carrier(s) from the cell group with uplink shall be configured closer to the uplink operating band than any of the downlink carriers from the cell group without uplink. 
     Sensitivity degradation is allowed for Intra-band contiguous EN-DC configurations, the reference sensitivity is defined only for the specific uplink and downlink test points and E-UTRA and NR single carrier requirements do not apply. 
     Sensitivity degradation is allowed for a band if it is impacted by UL harmonic interference from another band part of the same EN-DC configuration. Reference sensitivity exceptions for the victim band (high) are specified with uplink configuration of the agressor band (low). 
     Sensitivity degradation is allowed for a band if it is impacted by receiver harmonic mixing due to another band part of the same EN-DC configuration. Reference sensitivity exceptions for the victim band (low) are specified with uplink configuration of the agressor band (high). 
     Sensitivity degradation is allowed for a band if it is impacted by UL of another band part of the same EN-DC configuration due to cross band isolation issues. Reference sensitivity exceptions for the victim band are specified with uplink configuration of the agressor band specified. 
     For EN-DC configurations in NR FR1 the UE may indicate capability of not supporting simultaneous dual uplink operation due to possible intermodulation interference overlapping in frequency to its own primary downlink channel bandwidth if
         the intermodulation order is 2;   the intermodulation order is 3 when both operating bands are between 450 MHz-960 MHz or between 1427 MHz-2690 MHz       

     In the case for EN-DC configurations in NR FR1 for which the intermodulation products caused by dual uplink operation do not interfere with its own primary downlink channel bandwidth as defined in Annex I the UE is mandated to operate in dual and triple uplink mode. 
     For these test points the reference sensitivity levels are relaxed by the amount of the parameter MSD.

     Because frequency range made by frequency combination of DC_11+n28 affect to DL Fc of B11(=1490 MHz) in 7 MHz away, IMD3 in band 11 demand low MSD value for affection of side lobe impact unlike with directly affection of NR band n28. 
     On the other hand, because impulse value of IMD4 in n28 DL is 798.5 MHz, higher affection occurs.

For example, as shown in  FIG.  19   b   , if the UE transmits uplink signals via uplink bands of operating bands 41 and n3, IMD products are produced and then a reference sensitivity in operating band 18 is degraded. Therefore, a value of MSD is needed to apply the reference sensitivity. 
     Table 10 shows a MSD exception for Scell due to dual uplink operation for EN-DC_18 A-41A_n3A.

       FIG.  20    illustrates exemplary IMD by a combination of band 18, 41 and n77. 
     There are IMD5 products produced by Band 41 and n77 that impact the reference sensitivity of band 18. For example, as shown in  FIG.  20   , if the UE transmits uplink signals via uplink bands of operating bands 41 and n77, IMD products are produced and then a reference sensitivity in operating band 18 is degraded. Therefore, a value of MSD is needed to apply the reference sensitivity.

     IV-21. Proposed MSD level for DC_18 A-41A_n78A/DC_18 A-41C_n78A 
       FIG.  21    illustrates exemplary IMD by a combination of band 18, 41 and n78. 
     There are IMD5 products produced by Band 41 and n78 that impact the reference sensitivity of band 18. For example, as shown in  FIG.  21   , if the UE transmits uplink signals via uplink bands of operating bands 41 and n78, IMD products are produced and then a reference sensitivity in operating band 18 is degraded. Therefore, a value of MSD is needed to apply the reference sensitivity. 
     Table 10 shows MSD exception for Scell due to dual uplink operation for EN-DC_18 A-41A_n78A. 
       FIG.  22    is a flow chart showing an example of a procedure of a terminal according to the present disclosure. 
     Referring to  FIG.  22   , steps S 1210  to S 1230  are shown. Operations described below may be performed by the terminal. 
     For reference, step S 1210  may not always be performed when the terminal performs communication. For example, step S 1210  may be performed only when the reception performance of the terminal is tested. 
     In step S 1210 , the terminal may preset the above proposed MSD value. For example, the terminal may preset the MSD values in Table 10. For example, for the combination of the DC_28 A-n3A-n77A downlink band and the DC_28 A-n77A uplink band, an MSD of 17.0 dB may be applied to the reference sensitivity of the downlink band n3. 
     In step S 1220 , the terminal may transmit the uplink signal. 
     When the combination of the DC_28 A-n3A-n77A downlink band and the DC_28 A-n77A uplink band is configured in the terminal, the terminal may transmit the uplink signal through the uplink operating bands 28 and n77. 
     In step S 1230 , the terminal may receive the downlink signal. 
     The terminal may receive the downlink signal based on the reference sensitivity of the downlink band n3, to which the MSD value is applied. 
     When the combination of the DC_28 A-n3A-n77A downlink band and the DC_28 A-n77A uplink band is configured in the terminal, the terminal may receive the downlink signal through the downlink operating band n3. 
     For reference, the order in which steps S 1220  and S 1230  are performed may be different from that shown in  FIG.  24   . For example, step S 1230  may be performed first and then step S 1220  may be performed. Alternatively, step S 1220  and step S 1230  may be performed simultaneously. Alternatively, the time when step S 1220  and step S 1230  may be may overlap partially.
