Description

[0001] This application is a divisional application of the invention patent application with the application date of July 9, 2020, application number 202010655282.4, and invention name “Electronic device supporting dual connection and power control method thereof”. Technical Field

[0002] The present disclosure relates to an electronic device, and more particularly to an electronic device supporting dual connectivity and a power control method of the electronic device. Background Art

[0003] With the development of mobile communication technology, portable terminals providing various functions have become popular. Therefore, efforts are being made to develop the fifth generation (5G) communication system to meet the growing demand for wireless data services. In order to achieve high data transmission rates, in addition to the implementation methods in the high frequency bands already used by the third generation (3G) communication system and the long term evolution (LTE) communication system, the 5G communication system considers implementation methods in ultra-high frequency bands to provide high data transmission speeds.

[0004] As a method of implementing 5G communication, a standalone (SA) scheme and a non-standalone (NSA) scheme are considered. The NSA scheme may be a scheme that uses a new radio (NR) system together with an existing LTE system. In the NSA scheme, a user equipment (UE) may use an eNB in ​​an LTE system and a gNB in ​​an NR system. A technology that allows a user terminal to operate in different communication systems is called dual connectivity.

[0005] Dual connectivity was first proposed by 3GPP Release-12. According to the first proposal, in addition to the LTE system, it is recommended to use the 3.5GHz band as a dual connectivity for small cells. It is being discussed whether to implement the NSA scheme of 5G by using the LTE system as the primary node and the NR system as the secondary node in the dual connectivity recommended by 3GPP Release-12.

[0006] An electronic device supporting dual connectivity can perform communication via heterogeneous communication networks, and the electronic device supporting dual connectivity can separately include a communication processor for processing signals of each communication network. If fast data exchange between two separately included communication processors is difficult, the transmission power allowed by each electronic device may not be effectively used.

[0007] For example, if an electronic device supporting dual connectivity sends data via two communication networks at the same time, and the electronic device does not know the power-related information of the two communication networks, the electronic device may not be able to effectively utilize the maximum power (Pmax) resources allowed by the power level of the electronic device, but may simply control the power depending on the parameters provided from the network. In the case where the power is controlled by the network, the time delay may be relatively long, and therefore, the power resources may not be effectively used, and the performance and coverage may be deteriorated.

[0008] The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with respect to the present disclosure. Summary of the invention

According to another embodiment, the fourth RFIC 228 may be omitted or may be included as a part of the third RFIC 226.

[0072] The first communication processor 212 can establish a communication channel for a frequency band for wireless communication with the first cellular network 292, and can support traditional network communication via the established communication channel. According to various embodiments, the first cellular network 292 can be a traditional network including a 2G, 3G, 4G or long-term evolution (LTE) network. The second communication processor 214 can establish a communication channel corresponding to a specified frequency band (e.g., about 6 GHz to 60 GHz) among the frequency bands for wireless communication with the second cellular network 294, and can support 5G network communication via the established communication channel. According to various embodiments, the second cellular network 294 can be a 5G network defined in 3GPP. In addition, according to an embodiment, the first communication processor 212 or the second communication processor 214 can establish a communication channel corresponding to another specified frequency band (e.g., about 6 GHz or less) among the frequency bands for wireless communication with the second cellular network 294, and can support 5G network communication via the established communication channel.

[0074] Depending on the implementation, the first communication processor 212 may not be directly connected to the second communication processor 214. In this case, the first communication processor 212 may perform data transmission or reception with the second communication processor 214 via the processor 120 (e.g., an application processor). According to various embodiments, the first communication processor 212 or the second communication processor 214 may perform data transmission or reception with the processor 120 via a shared memory or a PCIe interface.

[0075] According to an embodiment, the first communication processor 212 and the second communication processor 214 may be implemented in a single chip or a single package. According to various embodiments, the first communication processor 212 or the second communication processor 214 may be implemented in a single chip or a single package together with the processor 120, the auxiliary processor 123, or the communication module 190. For example, Figure 2B As shown, the integrated communication processor 260 may support both functionality for communicating with a first cellular network and functionality for communicating with a second cellular network.

[0076] In the case of transmission, the first RFIC 222 may convert a baseband signal generated by the first communication processor 212 into a radio frequency (RF) signal in the range of about 700 MHz to 3 GHz for the first cellular network 292 (e.g., a legacy network). In the case of reception, an RF signal is obtained from the first cellular network 292 (e.g., a legacy network) via an antenna (e.g., the first antenna module 242) and may be pre-processed via an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the pre-processed RF signal into a baseband signal so that the baseband signal is processed by the first communication processor 212.

[0077] In the case of transmission, the second RFIC 224 may convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 into an RF signal (hereinafter, a 5G Sub6 RF signal) of a Sub6 frequency band (e.g., about 6 GHz or less) for a second cellular network 294 (e.g., a 5G network). In the case of reception, a 5G Sub6 RF signal is obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., the second antenna module 244) and may be pre-processed via an RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the pre-processed 5G Sub6 RF signal into a baseband signal so that the baseband signal is processed by a corresponding communication processor among the first communication processor 212 or the second communication processor 214.

[0078] The third RFIC 226 may convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, 5G 6 or above RF signal) of a 5G Above 6 frequency band (e.g., approximately 6 GHz to 60 GHz) for a second cellular network 294 (e.g., a 5G network). In the case of reception, the 5G 6 or above RF signal is obtained from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 244) and may be pre-processed via the third RFFE 236. The third RFIC 226 may convert the pre-processed 5G 6 or above RF signal into a baseband signal so that the baseband signal is processed by the second communication processor 214. According to an embodiment, the third RFFE 236 may be implemented as a part of the third RFIC 226.

[0079] According to an embodiment, the electronic device 101 may include a fourth RFIC 228 that is separate from the third RFIC 226 or as a part of the third RFIC 226. In this case, the fourth RFIC 228 may convert a baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, IF signal) in an intermediate frequency band (e.g., about 9 GHz to 11 GHz), and may transmit the IF signal to the third RFIC 226. The third RFIC 226 may convert the IF signal into a 5G 6 or higher RF signal. In the case of reception, the 5G 6 or higher RF signal is received from the second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and may be converted into an IF signal by the third RFIC 226. The fourth RFIC 228 may convert the IF signal into a baseband signal so that the baseband signal is processed by the second communication processor 214.

[0080] According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least a portion of a single chip or a single package. According to an embodiment, the first RFFE 232 and the second RFFE 234 may be implemented as at least a portion of a single chip or a single package. According to an embodiment, at least one antenna module of the first antenna module 242 or the second antenna module 244 may be omitted or may be combined with another antenna module in order to process RF signals in multiple frequency bands.

[0081] According to an embodiment, the third RFIC 226 and the antenna 248 may be disposed on the same substrate, and a third antenna module 246 may be formed. For example, the wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 is disposed on a portion (e.g., a lower portion) of the second substrate (e.g., a sub-PCB) that is different from the first substrate, and the antenna 248 is disposed on another portion (e.g., an upper portion), so that the third antenna module 246 may be formed. By disposing the third RFIC 226 and the antenna 248 on the same substrate, the length of the transmission line therebetween may be reduced. For example, this may reduce the loss (e.g., attenuation) of a signal in a high frequency band (e.g., approximately 6 GHz to 60 GHz) for 5G network communication, which loss is caused by a transmission line. Therefore, the electronic device 101 may improve the quality or speed of communication with the second cellular network 294 (e.g., a 5G network).

[0082] According to an embodiment, the antenna 248 may be implemented as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC 226 may be, for example, part of a third RFFE 236, and may include a plurality of phase shifters 238 corresponding to the plurality of antenna elements. In the case of transmission, each of the plurality of phase shifters 238 may shift the phase of a 5G 6 or higher RF signal to be transmitted to the outside of the electronic device 101 (e.g., a base station of a 5G network) via a corresponding antenna element. In the case of reception, each of the plurality of phase shifters 238 may shift the phase of a 5G 6 or higher RF signal received from the outside via a corresponding antenna element to the same or substantially the same phase. This may enable transmission or reception via beamforming between the electronic device 101 and the outside.

[0083] The second cellular network 294 (e.g., a 5G network) may operate independently of the first cellular network 292 (e.g., a legacy network) (e.g., standalone (SA)), or may operate by connecting thereto (e.g., non-standalone (NSA)). For example, in a 5G network, there may only be an access network (e.g., a 5G radio access network (RAN) or a next generation RAN (NG RAN)), and there may not be a core network (e.g., a next generation core (NGC)). In this case, the electronic device 101 may access the access network of the 5G network, and may access an external network (e.g., the Internet) under the control of the core network (e.g., the evolved packet core (EPC)) of the legacy network. Protocol information for communicating with a legacy network (e.g., LTE protocol information) or protocol information for communicating with a 5G network (e.g., new radio (NR) protocol information) may be stored in the memory 230 and may be accessed by another component (e.g., the processor 120, the first communication processor 212, or the second communication processor 214).

[0089] According to various embodiments, in a DC environment, one of the LTE base station or the NR base station may operate as a master node (MN) 310, and the other may operate as a secondary node (SN) 320. The MN 310 may be connected to the core network 330, and may send or receive control messages. The MN 310 and the SN 320 are connected via a network interface, and transmission or reception of messages related to management of radio resources (e.g., communication channels) may be performed therebetween.

[0090] According to various embodiments, the MN 310 may be implemented as an LTE base station, the SN 320 may be implemented as an NR base station, and the core network 330 may be implemented as an EPC. For example, a control message may be sent or received via the LTE base station and the EPC, and user data may be sent or received via at least one of the LTE base station and the NR base station.

[0091] According to various embodiments, the MN 310 may be implemented as an NR base station, the SN 320 may be implemented as an LTE base station, and the core network 330 may be implemented as a 5GC. For example, a control message may be sent or received via the NR base station and the 5GC, and user data may be sent or received via at least one of the LTE base station and the NR base station.

[0092] According to various embodiments, the electronic device 101 may register with at least one of the EPC or the 5GC, and may send or receive a control message.

[0093] According to various embodiments, the EPC or the 5GC may interwork to manage the communication of the electronic device 101. For example, movement information of the electronic device 101 may be transmitted or received via an interface between the EPC and the 5GC.

[0094] As described above, dual connectivity via an LTE base station and an NR base station may be referred to as E-UTRA New Radio Dual Connectivity (EN-DC).

[0095] Figure 4 is a diagram illustrating bearers in a user equipment (UE) according to an embodiment of the present disclosure.

[0096] refer to Figure 4 , in a 5G non-standalone network environment (e.g. Figure 3The bearers available in the network environment 300a) may include a primary cell group (MCG) bearer, a secondary cell group (SCG) bearer, and a split bearer. A user equipment (UE) 400 may be configured with an E-UTRA / NR Packet Data Convergence Protocol (E-UTRA / NR PDCP) entity 401 and NR PDCP entities 402 and 403. The UE 400 may be configured with E-UTRA Radio Link Control (E-UTRA RLC) entities 411 and 412, and NR RLC entities 413 and 414. The UE 400 may be configured with an E-UTRA MAC entity 421 and an NR MAC entity 422. The UE may be a user equipment capable of performing communication with a base station, and may communicate with the base station. Figure 1 For example, in various embodiments, UE performing a predetermined operation may refer to at least one element included in the electronic device 101 performing a predetermined operation.

[0097] For example, MCG can correspond to Figure 3 The master node (MN) 310 of the SCG may correspond to, for example, Figure 3 If the node is determined to be used for communication, the UE 400 may configure Figure 4 The various entities shown are used to communicate with the determined node (e.g., base station). The entities 401, 402, and 403 in the PDCP layer can receive data (e.g., PDCP SDU corresponding to an IP packet), and can output converted data (e.g., PDCP protocol data unit (PDU)) to which additional information (e.g., header information) is applied. The entities 411, 412, 413, and 414 in the RLC layer can receive converted data (e.g., PDCP PDU) output from the entities 401, 402, and 403 in the PDCP layer, and can output converted data (e.g., RRLC PDU) to which additional information (e.g., header information) is applied. The entities 421 and 422 in the MAC layer can receive converted data (e.g., RLC PDU) output from the entities 411, 412, 413, and 414 in the RLC layer, can output converted data (e.g., MAC PDU) to which additional information (e.g., header information) is applied, and can transmit it to the physical layer (not shown).

[0098] In DC, an MCG bearer may be associated with a path (or data) via which data is sent or received using only an entity or resource corresponding to an MN. In DC, an SCG bearer may be associated with a path (or data) via which data is sent or received using only a resource or entity corresponding to an SN. In DC, a split bearer may be associated with a path (or data) via which data is sent or received using either an entity or resource corresponding to an MN or a resource or entity corresponding to an SN. Thus, Figure 4 As shown, the split bearer can be associated with all E-UTRA RLC entities 412 and NR RLC entities 413 and E-UTRA MAC entities 421 and NR MAC entities 422 via the NR PDCP entity 402.

At least a portion of the second signal transmitted via the second coupler 560b may be fed back and provided to the second transceiver 530b.

[0111] According to various embodiments, the first transceiver 530a and / or the second transceiver 530b may receive a transmission feedback signal fed back from the first coupler 560a and / or the second coupler 560b, and may change the frequency using an internal local oscillator (LO) so as to process it into a baseband signal. According to various embodiments, the first transceiver 530a and the second transceiver 530b may convert a baseband signal corresponding to the transmission power into a digital signal using an analog-to-digital converter (ADC), and may send the digital signal to the first communication processor 520a or the second communication processor 520b.

[0112] According to various embodiments, the first communication processor 520a may control the gain of the first signal transmitted via the first transceiver 530a, and may control the bias of the first power amplifier 540a according to the control signal. The second communication processor 520b may control the gain of the second signal transmitted via the second transceiver 530b, and may control the bias of the second power amplifier 540b according to the control signal.

[0113] According to various embodiments, Figure 5 In the electronic device providing dual connection shown, the transceivers 530a and 530b can convert the sensing signals input via the FBRX ports (FBRX1 and FBRX2) into baseband signals, can pass the signals through an analog / digital converter (ADC), and can send the digitized sensing signals to the communication processors 520a and 520b connected thereto.

[0117] refer to Figure 6 , the first communication uplink (UL) frequency band and the second communication uplink (UL) frequency band may be arranged as shown. According to an embodiment, the first communication (e.g., LTE communication) uplink frequency band may include FR1, FR2, or FR3 frequency band. The FR1 frequency band has a frequency range of FR1_1 to FR1_h. The FR2 frequency band has a frequency range of FR2_1 to FR2_h. The FR3 frequency band has a frequency range of FR3_1 to FR3_h. The second communication (e.g., 5G communication) uplink frequency band may have a frequency range of F_1 to F_h

[0118] According to various embodiments, if an uplink signal based on the first communication and an uplink signal based on the second communication are transmitted simultaneously, an IMD component frequency may be generated. The IMD component frequency may be generated in different frequency bands. For example, the third order (3 rd The third order IMD component frequency region may be “2×first communication frequency-second communication frequency”. According to various embodiments, the third order IMD component frequency region may at least partially overlap with the first communication downlink (DL) frequency band. Therefore, the third order IMD component frequency signal may affect the reception of the first communication downlink signal.

[0119] like Figure 5 and 6As shown, in the case of providing a dual-connected electronic device, in order to access two communication networks, two or more TX transmissions are performed in a single electronic device. Therefore, harmonic / intermodulation interference or intermodulation parasitics may occur. According to various embodiments, if different communication technologies are difficult to be physically far away from each other due to the internal space limitations of the electronic device, the maximum power reduction (MPR) can be applied to the extent that interference and parasitics do not cause problems. If the maximum power reduction is applied, the uplink coverage (UL coverage) may deteriorate. According to the various embodiments described below, the information of the first signal sent via the first transceiver 530a can be monitored in real time, and control can be performed so that the MPR is not excessively applied to the signal sent via the second transceiver 530b.

[0210] Referring to Table 1, a noise component generated by the second-order IMD between two uplink signals may exist in a frequency band ranging from 1835 to 1865 MHz, which may overlap with the LTE B3 downlink frequency band ranging from 1830 to 1860 MHz.

[0211] For example, the magnitude of the second order IMD component may be expressed as given in Equation 1.

[0212] Second-order IMD component size = LogA + dBm (LTE B3 power) + dBm (5G n78 power)

[0213] Rate) Equation 1 Based on Equation 1, LogA can be expressed as given in Equation 2.

[0214] LogA = the second-order IMD component size measured for the UE - dBm (LTE B3 power) - dBm (5G n78 power) Equation 2

[0215] For example, if it is assumed that the B3 TX power is 15 dBm, and the n78 TX power is 20 dBm, and the magnitude of the measured second-order IMD component is -60 dBm, then LogA = -60 - 15 - 20 = -95.

[0216] According to an embodiment, by measuring some terminals when manufacturing the electronic device, the value of LogA can be obtained from Equation 2 and can be stored in the memory of the electronic device in the form of NV parameters. According to various embodiments, if it is desired to keep the sensitivity reduction in the B3 reception band caused by the second-order IMD component within N dB, the maximum power of the n78 UL signal can be determined based on Equation 3.

[0217] dBm(5G n78 maximum UL power_IMD) = B3 receive sensitivity + N-LogA-dBm(LTE B3 UL power) Equation 3

[0218] According to various embodiments, if the maximum power is applied and the corresponding ENDC communication supports power level 3, the sum of the LTE UL power and the 5G UL power exceeding 23dBm may not be allowed. According to this condition, the n78 UL power may have another upper limit given in Equation 4.

[0219] dBm(5G n78 maximum UL power_Pclass) = 23-dBm(LTE B3 UL power)

[0220] Equation 4

[0221] According to various embodiments, the n78 UL power may be set to the minimum of the two upper limit conditions of Equation 3 and Equation 4, as given in Equation 5.

[0222] dBm(5G n78 maximum UL power) = Min(dBm(5G n78 maximum UL power_IMD), dBm(5G n78 maximum UL power_Pclass)) Equation 5
