Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of Korean Patent Applications No. 10-2021-0004816 filed on Jan. 13, 2021, the contents of which are all hereby incorporated by reference herein in their entirety 
     BACKGROUND OF THE DISCLOSURE 
     Field of the Disclosure 
     The present disclosure relates to mobile communication 
     Related Art 
     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. 
     SUMMARY OF THE DISCLOSURE 
     In accordance with an embodiment of the present disclosure, a disclosure of this specification provides a device configured to operate in a wireless system, the device comprising: a transceiver configured with an Evolved Universal Terrestrial Radio Access (E-UTRA)-New Radio (NR) Dual Connectivity (EN-DC), wherein the EN-DC is configured to use three bands, a processor operably connectable to the transceiver, wherein the processer is configured to: control the transceiver to receive a downlink signal, control the transceiver to transmit an uplink signal via at least two bands among the three bands, wherein a value of Maximum Sensitivity Degradation (MSD) is applied to a reference sensitivity for receiving the downlink signal, wherein the value of the MSD is 4.5 dB for band n5, based on the three bands being bands 13, n5 and n77. 
     The present disclosure can have various advantageous effects. 
     For example, by performing disclosure of this specification, UE can transmit signal with dual uplink by applying MSD value. 
     Advantageous effects which can be obtained through specific embodiments of the present disclosure are not limited to the advantageous effects listed above. For example, there may be a variety of technical effects that a person having ordinary skill in the related art can understand and/or derive from the present disclosure. Accordingly, the specific effects of the present disclosure are not limited to those explicitly described herein, but may include various effects that may be understood or derived from the technical features of the present disclosure.

       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., LIE) 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 (IAB)), 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).

     &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. 5A to 5C  are exemplary diagrams illustrating exemplary architectures for services of the next generation mobile communication. 
     Referring to  FIG. 5A , 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. 5B , unlike  FIG. 5A , 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. 5A and 5B  is called non-standalone (NSA). 
     Referring to  FIG. 5C , 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. 6  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. 6 , 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. 6 , 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. 6 , 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. 6 , 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. 6 , 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 Specification 
     When a power class 3 terminal performs an EN-DC operation, self-interference occurring in the terminal is analyzed, and a relaxed standard for sensitivity thereof is proposed. 
     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 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 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. 
     The analysis on the sensitivity degradation is an analysis method of how the effect of noise raising on the non-lineality characteristic of dual uplink transmission at the transmitting end affects the receiving end in terms of sensitivity. The structure of the terminal (1Tx &amp; 1PA, 1Tx/2PA structure or 2Tx/2PA structure), devices used (Cascaded diplexer structure, Duplexer-Triplexer, duplexer-Quadplexer structure, etc.) and isolation levels for each device (antenna isolation, PCB isolation, PA to PA isolation, PA to LNA) Isolation, etc.) was used to analyze the effect on Tx noise raising, which is caused by a complex occurrence of all effects, on the decrease in Rx sensitivity at the frequency of the self-receiving area. Unlike mathematically calculating the reception sensitivity, it is a value measured and analyzed considering the device characteristics of the corresponding terminal. 
     In particular, intermodulation in terminals composed of active elements (PA, LNA) is a component that occurs as a single nonlinear characteristic, and when it occurs in the wanted signal and adjacent bands, it does not disappear even using a filter and continues to be additional nonlinearity. It has the properties to produce ingredients. 
     Here, the constant coefficient represents the DC component (A) and the amplification ratio of the original signal (B), and from the part of the second term, the harmonic/IMD component generated by the active element at 2×/3× is generated. 
     That is, the harmonics/IMD component is a trigonometric function C*[acos(w 1 t)+bcos(w 2 t)] 2  of the quadratic term, which creates a nonlinear component generated by mixing several signals as follows. It is created in a complex manner and exhibits non-linear characteristics. 
         C *[ a  cos( w   1   t )+ b  cos( w   2   t )] 2    
       = C *[ a   2  cos 2 ( w   1   t )+2 ab  cos( w   1   t )cos( w   2   t )+ b   2  cos 2 ( w   2   t )] 
       = C *[ a   2 *(1+cos(2 w   1   t ))/2+ ab  cos( w   1   +w   2 ) t+ab  cos( w   1   −w   2 ) t+b   2 *(1+cos(2 w   2   t ))/2] 
       =0.5 C ( a   2   +b   2 )+0.5 Ca   2  cos(2 w   1   t )+0.5 Cb   2  cos(2 w   2   t )+ Cab  cos( w   1   +w 2=) t+Cab  cos( w 1− w 2) t  
 
     Here, the constant 0.5C (a 2 +b 2 ) value representing the non-linear characteristic and the 0.5Ca 2  cos(2w 1 t) and 0.5Cb 2  cos(2w 2 t) components expressed as first-order terms represent the harmonic components according to each frequency, and Cabcos(w 1 +w 2 )t and Cabcos(w 1 −w 2 )t show that the IMD component generated when a and b signals are transmitted at the same time occurs at the corresponding frequency. 
     The influence on the 3rd and 4th order or higher functions is also shown by adding more non-linear characteristics as above, and the non-linear characteristics according to these equations appear complexly at the receiving end. 
     Therefore, in 5G NR, since a high power terminal supports at a high frequency in a channel bandwidth wider than that of existing mobile communication, the characteristics of the corresponding band of the terminal element are identified and used, By identifying and analyzing the factors caused by noise increase and non-linear characteristics that components have on the receiving end, the sensitivity reduction of the receiving end can be analyzed.

     Test configuration for testing MSD according to the above self-interference analysis and parameters of FE devices according to each RF architecture were analyzed. 
     In rel-17 DC of LTE x Bands (xDL/1UL, x=1, 2, 3, 4) and NR 2 Bands (2DL/1UL) basket WI, RAN4 also consider shared antenna RF architectures for NSA UE in sub-6 GHz as LTE system. So we consider shared antenna RF architecture for general NSA DC UE to derive MSD levels. Also separate antenna RF architecture is considered in some specific band combinations which was considered in general NR RF session. 
     For the MSD analysis of these several DC band combinations between LTE and NR, we assume the following parameters and attenuation levels based on current UE RF FE components as shown in Table 8 and 9. 
     Table 8 shows the RF component isolation parameters to derive MSD level at sub-6 GHz.

     6. DC_13_n5-n77 
     There are IMD3 &amp; IMD4 produced by Band 13 and NR band n77 that impact the reference sensitivity of NR band n5. 
       FIG. 7  illustrates exemplary IMD by a combination of band 13, n5 and n77. 
     There are IMD5 products produced by Band 13 and n77 that impact the reference sensitivity of Band n5. For example, as shown in  FIG. 7 , if the UE transmits uplink signals via uplink bands of operating bands 13 and n77, IMD products are produced and then a reference sensitivity in operating band n5 is degraded. Therefore, a value of MSD is needed to apply the reference sensitivity. 
     The required MSD levels and test configuration are shown in Table 16. 
     Table 16 shows Reference sensitivity exceptions for Scell due to dual uplink operation for DC in NR FR1 (three bands).

       FIG. 8  is a flow chart showing an example of a procedure of a terminal according to the present disclosure. 
     Referring to  FIG. 8 , steps S 810  to S 830  are shown. Operations described below may be performed by the terminal. 
     For reference, step S 810  may not always be performed when the terminal performs communication. For example, step S 810  may be performed only when the reception performance of the terminal is tested. 
     In step S 810 , the terminal may preset the above proposed MSD value. For example, the terminal may preset the MSD values in Table 16. For example, for the combination of the DC_13_n5-n77 downlink band and the DC_13-n77 uplink band, an MSD of 4.5 dB may be applied to the reference sensitivity of the downlink band n5. 
     In step S 820 , the terminal may transmit the uplink signal. 
     When the combination of the DC_13_n5-n77 downlink band and the DC_13-n77 uplink band is configured in the terminal, the terminal may transmit the uplink signal through the uplink operating bands 13 and n77. 
     In step S 830 , the terminal may receive the downlink signal. 
     The terminal may receive the downlink signal based on the reference sensitivity of the downlink band n5, to which the MSD value is applied. 
     When the combination of the DC_13_n5-n77 downlink band and the DC_13-n77 uplink band is configured in the terminal, the terminal may receive the downlink signal through the downlink operating band n5. 
     For reference, the order in which steps S 820  and S 830  are performed may be different from that shown in  FIG. 8 . For example, step S 830  may be performed first and then step S 820  may be performed. Alternatively, step S 820  and step S 830  may be performed simultaneously. Alternatively, the time when step S 820  and step S 830  may be may overlap partially.
