Description

[0001] The present disclosure relates to an electronic device that performs a handover operation based on transmission capability, a method of operation thereof, and a storage medium.

To achieve high data rates and provide faster data transmission speeds, the 5G communication system is designed to provide faster data transmission speeds. rd In addition to the frequency bands used in generation (3G) communication systems and long term evolution (LTE) communication systems, implementation in higher frequency bands (e.g., 25–60 GHz band) is being considered.

[0079] Referring to FIG. 2a, an electronic device (101) (e.g., the electronic device (101) of FIG. 1) may include a first communication processor (212), a second communication processor (214), a first radio frequency integrated circuit (RFIC) (222), a second RFIC (224), a third RFIC (226), a fourth RFIC (228), a first radio frequency front end (RFFE) (232), a second RFFE (234), a first antenna module (242), a second antenna module (244), a third antenna module (246), and antennas (248). The electronic device (101) may further include a processor (120) and a memory (130). A second network (199) may include a first cellular network (292) and a second cellular network (294). According to one embodiment, the electronic device (101) may further include at least one of the components described in FIG. 1, and the second network (199) may further include at least one other network. According to one embodiment, the first communication processor (212), the second communication processor (214), the first RFIC (222), the second RFIC (224), the fourth RFIC (228), the first RFFE (232), and the second RFFE (234) may form at least a part of the wireless communication module (192). According to one embodiment, the fourth RFIC (228) may be omitted or may be included as part of the third RFIC (226).

[0080] The first communication processor (212) can support the establishment of a communication channel of a band to be used for wireless communication with the first cellular network (292), and legacy network communication through the established communication channel. According to one embodiment, the first cellular network is a second generation (2 nd generation: 2G) network, 3rd generation (3 rdgeneration: 3G) network, 4th generation (4 th It may be a legacy network including a generation (4G) network or a long term evolution (LTE) network. The second communication processor (214) may support the establishment of a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel. According to one embodiment, the second cellular network (294) may be a 5G network defined by the 3rd generation partnership project (3GPP). Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support the establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or lower) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0081] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted through the second cellular network (294) can be changed to be transmitted through the first cellular network (292). In this case, the first communication processor (212) can receive transmitted data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) through the inter-processor interface (213). The above inter-processor interface (213) may be implemented, for example, as a UART (universal asynchronous receiver / transmitter) interface (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express), but there is no limitation on the type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information, for example, using shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output strength, and resource block (RB) allocation information, with the second communication processor (214).

[0082] According to one embodiment, 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 transmit and receive data to and from the second communication processor (214) through a processor (120) (e.g., an application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data to and from the processor (120) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) using shared memory.

[0083] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented within a single chip or a single package. According to one embodiment, the first communication processor (212) or the second communication processor (214) may be formed within a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190). For example, as shown in FIG. 2b, the integrated communication processor (260) may support both the function for communication with the first cellular network (292) and the function for communication with the second cellular network (294).

[0084] The first RFIC (222) can convert a baseband signal generated by the first communication processor (212) during transmission into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network (292) (e.g., legacy network). During reception, the RF signal is acquired from the first cellular network (292) through an antenna (e.g., the first antenna module (242)) and can be preprocessed through an RFFE (e.g., the first RFFE (232)). The first RFIC (222) can convert the preprocessed RF signal into a baseband signal so that it can be processed by the first communication processor (212).

[0085] The second RFIC (224) can convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) during transmission into an RF signal of the Sub6 band (e.g., about 6 GHz or lower) used in the second cellular network (294) (e.g., 5G network) (hereinafter, 5G Sub6 RF signal). During reception, the 5G Sub6 RF signal is acquired from the second cellular network (294) through an antenna (e.g., the second antenna module (244)) and can be preprocessed through an RFFE (e.g., the second RFFE (234)). The second RFIC (224) can convert the preprocessed 5G Sub6 RF signal into a baseband signal so that it can be processed by the corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0086] The third RFIC (226) can convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, 5G Above6 RF signal) of the 5G Above6 band (e.g., about 6 GHz to about 60 GHz) used in the second cellular network (294). Upon reception, the 5G Above6 RF signal may be acquired from the second cellular network (294) via an antenna (e.g., antenna (248)) and preprocessed via the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) may be formed as part of the third RFIC (226).

[0087] According to one embodiment, the electronic device (101) may include a fourth RFIC (228) separately from or at least as 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 referred to as an IF signal) in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular network (294) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0088] According to one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as at least part of a single chip or a single package. According to one embodiment, if the first RFIC (222) and the second RFIC (224) in FIG. 2a or FIG. 2b are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and the converted signal may be transmitted to either the first RFFE (232) or the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least part of a single chip or a single package. According to one embodiment, at least one of the first antenna module (242) or the second antenna module (244) may be omitted or combined with another antenna module to process RF signals of a corresponding number of bands.

[0089] According to one embodiment, the third RFIC (226) and the antenna (248) may be placed on the same substrate to form a third antenna module (246). For example, a wireless communication module (192) or a processor (120) may be placed on the first substrate (e.g., main PCB). In this case, the third RFIC (226) may be placed on a portion of a second substrate (e.g., sub PCB) separate from the first substrate (e.g., bottom surface), and the antenna (248) may be placed on another portion of a second substrate (e.g., top surface) to form the third antenna module (246). By placing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line between them. This can, for example, reduce the loss (e.g., attenuation) of signals in the high-frequency band (e.g., about 6 GHz to about 60 GHz) used for 5G network communication by the transmission line. As a result, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0090] According to one embodiment, the antenna (248) may be formed as an antenna array comprising a plurality of antenna elements that can be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). During transmission, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device (101) (e.g., a base station of a 5G network) through the corresponding antenna element. During reception, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal received from the outside through the corresponding antenna element to the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device (101) and the outside.

[0091] The second cellular network (294) may operate independently of the first cellular network (292) (e.g., stand-alone (SA)) or be connected to the first cellular network (292) and operated (e.g., non-stand-alone (NSA)). For example, in a 5G network, only an access network (e.g., 5G radio access network (RAN) or next generation RAN (NG RAN)) may exist, and a core network (e.g., next generation core (NGC)) may not exist. In this case, after the electronic device (101) accesses the access network of the 5G network, it may access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., evolved packet core (EPC)). Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., new radio (NR) protocol information) is stored in memory (130) and can be accessed by other parts (e.g., processor (120), first communication processor (212), or second communication processor (214)).

[0092] FIG. 2b is a block diagram (250) of an electronic device for supporting legacy network communication and 5G network communication according to one embodiment.

[0093] Referring to FIG. 2b, an electronic device (101) (e.g., the electronic device (101) of FIG. 1) may include an integrated communication processor (260), a first RFIC (222), a second RFIC (224), a third RFIC (226), a fourth RFIC (228), a first RFFE (232), a second RFFE (234), a first antenna module (242), a second antenna module (244), a third antenna module (246), and / or antennas (248). The electronic device (101) may further include a processor (120) and a memory (130). A second network (199) may include a first cellular network (292) and a second cellular network (294).

[0094] The block diagram (250) of the electronic device (101) shown in FIG. 2b differs from the block diagram (200) of the electronic device (101) shown in FIG. 2a only in that the first communication processor (212) and the second communication processor (214) are implemented as an integrated communication processor (260), and the remaining components included in the block diagram (250) of the electronic device (101) may be implemented similarly or substantially identically to the components included in the block diagram (200) of the electronic device (101) shown in FIG. 2a, and therefore, a detailed description thereof is omitted.

[0095] FIG. 3a is a drawing illustrating a wireless communication system providing a network of legacy communication and / or 5G communication according to one embodiment.

[0096] Referring to FIG. 3a, the network environment (300a) may include at least one of a legacy network and a 5G network. In one embodiment, the legacy network may include a 4G or LTE base station of 3GPP standard (e.g., eNB(eNodeB)) that supports wireless access to an electronic device (101) (e.g., the electronic device (101) of FIG. 1, FIG. 2a, or FIG. 2b) and an EPC that manages 4G communication. The 5G network may include an NR base station (e.g., gNB(gNodeB)) that supports wireless access to an electronic device (101) and a 5GC that manages 5G communication of the electronic device (101).

[0097] According to one embodiment, the electronic device (101) may transmit and receive control messages and user data via legacy communication and / or 5G communication. The control message may include a message related to at least one of security control, bearer setup, authentication, registration, or mobility management of the electronic device (101). User data may refer to user data excluding control messages transmitted and received between the electronic device (101) and the core network (330) (e.g., the EPC (342) in FIG. 3c).

[0098] The electronic device (101) can transmit and receive at least one of control messages or user data with at least one part of a 5G network (e.g., NR base station, 5GC) using at least part of a legacy network (e.g., LTE base station, EPC).

[0099] According to one embodiment, the network environment (300a) may include a network environment that provides dual connectivity (DC) to an LTE base station and an NR base station, and transmits and receives control messages to and from an electronic device (101) through a core network (330) of either an EPC or a 5GC.

[0100] According to one embodiment, in a DC environment, one of the LTE base station or NR base station may operate as a master node (MN) (310) and the other as a secondary node (SN) (320). The MN (310) may be connected to a core network (330) to transmit and receive control messages. The MN (310) and the SN (320) may be connected via a network interface to transmit and receive messages related to the management of wireless resources (e.g., communication channels) to each other.

[0101] According to one embodiment, the MN (310) may be composed of an LTE base station, the SN (320) of an NR base station, and the core network (330) of an EPC. For example, control messages may be transmitted and received through the LTE base station and the EPC, and user data may be transmitted and received through at least one of the LTE base station or the NR base station.

[0102] According to one embodiment, the MN (310) may include an NR base station, the SN (320) may include an LTE base station, and the core network (330) may include a 5GC. For example, control messages may be transmitted and received through the NR base station and the 5GC, and user data may be transmitted and received through at least one of the LTE base station or the NR base station.

[0103] FIG. 3b is a drawing illustrating a wireless communication system providing a network of legacy communication and / or 5G communication according to one embodiment.

[0104] Referring to FIG. 3b, the network environment (300b) may include at least one of a legacy network and a 5G network. In one embodiment, the legacy network may include a 4G or LTE base station of 3GPP standard (e.g., eNB(eNodeB)) that supports wireless access to an electronic device (101) (e.g., the electronic device (101) of FIG. 1, FIG. 2a, or FIG. 2b) and an EPC that manages 4G communication. The 5G network may include an NR base station (350) (e.g., gNB(gNodeB)) that supports wireless access to an electronic device (101) and a 5GC (352) that manages 5G communication of the electronic device (101).

[0105] According to one embodiment, the electronic device (101) can transmit and receive control messages and user data via legacy communication and / or 5G communication.

[0106] The 5G network may include an NR base station (350) and a 5GC (352), and can transmit and receive control messages and user data independently of the electronic device (101).

[0107] FIG. 3c is a drawing illustrating a wireless communication system providing a network of legacy communication and / or 5G communication according to one embodiment.

[0108] Referring to FIG. 3c, the network environment (300c) may include at least one of a legacy network and a 5G network. In one embodiment, the legacy network may include a 4G or LTE base station (340) of 3GPP standards that supports wireless access to an electronic device (101) (e.g., the electronic device (101) of FIG. 1, FIG. 2a, or FIG. 2b) and an EPC (342) that manages 4G communication. The 5G network may include an NR base station (350) that supports wireless access to an electronic device (101) (e.g., a gNB (gNodeB)) and a 5GC (352) that manages 5G communication of the electronic device (101).

[0109] According to one embodiment, the electronic device (101) can transmit and receive control messages and user data via legacy communication and / or 5G communication.

[0110] According to one embodiment, the legacy network and the 5G network can each provide data transmission and reception independently. For example, the electronic device (101) and the EPC (342) can transmit and receive control messages and user data through the LTE base station (340). In another example, the electronic device (101) and the 5GC (352) can transmit and receive control messages and user data through the NR base station (350).

[0111] According to one embodiment, the electronic device (101) can be registered with at least one of the EPC (342) or 5GC (352) to send and receive control messages.

[0112] According to one embodiment, the EPC (342) or 5GC (352) may interwork to manage the communication of the electronic device (101). For example, movement information of the electronic device (101) may be transmitted and received through an interface between the EPC (342) and 5GC (352).

[0113] As described above, the DC through the LTE base station (340) and the NR base station (350) may be named EN-DC (E-UTRA new radio dual connectivity).

[0114] 4th generation (4 thIn mobile communication systems such as generation: 4G) communication systems and 5G communication systems, handovers can be classified according to their purpose into intra-frequency handover, inter-frequency handover, and inter-RAT handover, and events triggering measurement reporting can be classified into events A1 to A6, event B1, and event B2.

[0115] In a mobile communication system, a handover operation can be performed based on reception strength, such as, for example, reference signal received power (RSRP) and / or reference signal received quality (RSRQ). Therefore, in current mobile communication systems, an electronic device (e.g., a smartphone) can perform a handover operation using only the receiving capability of the electronic device (e.g., including reception strength).

[0116] However, performing a handover operation using only the receiving capability may be suitable when the receiving capability and the transmitting capability are relatively similar, and when the transmitting capabilities of the electronic devices used in the frequency bands supported by the electronic devices are relatively similar. For example, the receiving capability may include a receiving strength such as RSRP and / or RSRQ, and the transmitting capability may include a maximum transmitting power. For example, the receiving capability for a frequency band may include a receiving strength for the frequency band, and the transmitting capability for a frequency band may include a maximum transmitting power for the frequency band.

[0117] Meanwhile, electronic devices are being simplified for the efficient use of the system, and antennas are also required to be simplified while satisfying high-gain characteristics. Electronic devices generate electromagnetic waves, and the transmission power of the antenna may be increased to improve transmission performance. The specific absorption rate (SAR) is a numerical value representing the degree to which these generated electromagnetic waves are absorbed by the human body. SAR uses the unit KW / g (or mW / g), which can represent the amount of power (KW, W, or mW) absorbed per gram of the human body. As the issue of the harmful effects of electromagnetic waves on the human body has emerged, various SAR standards limiting the SAR of electronic devices are being proposed.

[0118] An electronic device may perform a back-off operation for the transmission power (or, the maximum value of the transmission power, or the maximum transmission power limit (MTPL)) when, for example, the expected SAR based on the transmission power is expected to exceed a threshold value. For example, when the electronic device detects a specific event (e.g., a grip, a hot spot, and / or a proxy), it may transmit a communication signal using the transmission power that has been backed off in response to the specific event, or transmit a communication signal using the transmission power set based on the back-off MTPL.

[0119] In addition, a technique for backoff transmission power (or MTPL) based on the total amount of SAR values ​​accumulated over a set time (e.g., time average SAR: TAS value) (or the average value of SARs generated over a set time) is also used. Just as SARs that instantaneously affect the human body need to be considered, SARs that affect the human body on average also need to be considered. Accordingly, if the total amount of accumulated SARs (or the average value of SARs generated over a set time) satisfies a set condition, a backoff operation for transmission power (or MTPL) can be performed.

[0120] Due to various operations that consider SAR (or TAS), such as back-off operations, the average transmit power of an electronic device can vary significantly depending on which of the multiple frequency bands supported by the electronic device is used. In particular, for some of the multiple frequency bands, the maximum transmit power may be set very low to limit SAR, and thus, in a weak field environment where the received strength is below the threshold strength, communication may become impossible, such as with call drops and / or radio link failure (RLF).

[0121] Accordingly, the present disclosure may propose an electronic device and a method of operation thereof that perform a handover operation based on not only a receiving capability but also a transmitting capability.

[0122] Figure 4 is a diagram illustrating events used for measurement reporting in a mobile communication system.

[0123] Referring to FIG. 4, various events are specified in a mobile communication system for measurement reporting, and FIG. 4 illustrates the threshold values ​​and hysteresis values ​​for events A1 to A6 among the events used for measurement reporting. For example, events A1 to A6 can be represented as shown in Table 1 below.

[0124]

[0125]

[0126] Events A1 through A6, as shown in Table 1, can be implemented similarly or substantially identically to those specified in V18.2.0 of 3GPP technical specification (TS) 36.331, and thus redundant descriptions may be omitted here.

[0127] Event A3 may occur (or be triggered) when the signal strength (or power and / or quality) received from an adjacent base station (or adjacent cell or secondary cell: S Cell) improves by more than an offset compared to the signal strength received from a serving base station (or serving cell or primary cell: P Cell), and may be used in both in-frequency and cross-frequency handovers. When Event A3 is triggered, it may indicate that the condition of the adjacent base station has significantly improved and that it can become a target base station for handover.

[0128] Figure 5 is a diagram illustrating a handover based on event A3 in a mobile communication system.

[0129] Referring to FIG. 5, reference number 520 may represent the signal strength received from a serving base station, and reference number 530 may represent the signal strength received from an adjacent base station. If a set condition (e.g., a condition in which the signal strength (or power and / or quality) received from an adjacent base station (or adjacent cell or S Cell) is better than the signal strength received from a serving base station (or serving cell or P Cell) by more than an offset) is not satisfied, event A3 may not be triggered. Alternatively, event A3 may be triggered if the signal strength received from an adjacent base station (or adjacent cell or S Cell) is better than the signal strength received from a serving base station (or serving cell or P Cell) by more than an offset. However, handover is not performed immediately at the moment when the signal strength received from an adjacent base station becomes greater than the signal strength received from the serving base station by an offset, but can be performed if, from the time when event A3 is triggered, the signal strength received from the adjacent base station remains greater than the signal strength received from the serving base station by an offset during the time to trigger (TTT), that is, if the A3 trigger condition persists for the TTT time. For example, event A3 can be triggered when the condition of Equation 1 below is satisfied.

[0130] <Mathematical Formula 1>

[0131] Neighbor cell RSRP > serving cell RSRP+(A3-offset+hysteresis) / 2

[0132] Mathematical Formula 1 is merely an example to aid understanding, and embodiments of the present disclosure are not limited thereto. For example, Mathematical Formula 1 may be modified, applied, or extended in various ways.

[0133] In Equation 1, Neighbour cell RSRP represents the RSRP of the signal received from the adjacent base station, serving cell RSRP represents the RSRP of the signal received from the serving base station, A3-offset represents the offset applied to event A3, and hysteresis represents the hysteresis parameter applied to event A3. A3-offset and hysteresis can be set by the serving base station, for example, (A3-offset+hysteresis) / 2 can be set to about 2 to 5 dB.

[0134] For example, if A3-offset is set to 6 and hysteresis to 2 (A3-offset+hysteresis) / 2 = 4), if the signal strength received from an adjacent base station is 3dB or greater than the signal strength received from the serving base station, the TTT for triggering Event A3 begins to count, and if, even after the TTT has elapsed, the signal strength received from the adjacent base station is 4dB or greater than the signal strength received from the serving base station, Event A3 may be triggered. Upon triggering Event A3, the electronic device may transmit a measurement report message containing the measurement results to the serving base station. Thus, as the measurement report message is transmitted to the serving base station, an operation for handover may be performed.

[0135] In current mobile communication systems, an electronic device may determine whether to perform a handover operation based solely on the device's receiving capability. For example, receiving capability may include the strength (or power and / or quality) of the received signal, such as RSRP and / or RSRQ. However, due to various operations that consider SAR (or TAS), such as back-off operations, the average transmit power of the electronic device can vary significantly depending on which of the multiple frequency bands supported by the device is used. Therefore, if the decision to perform a handover operation is made based solely on the device's receiving capability, a problem may arise where performance is degraded due to the device's transmit capability. For example, transmit capability may include the maximum transmit power. For example, receiving capability for a frequency band may include the strength (or power and / or quality) of the signal received in the frequency band, and transmit capability for a frequency band may include the device's maximum transmit power for that frequency band.

[0136] Table 2 below may show the transmission capability and reception capability by frequency band. For example, the transmission capability may include TRP (total radiated power), and the reception capability may include TIS (total isotropic sensitivity).

[0137] Table 2

[0138]

[0139] In Table 2, TX0 may represent, for example, an antenna located at the bottom of the electronic device among a plurality of antennas included in the electronic device, and TX1 may represent an antenna located at the top of the electronic device among a plurality of antennas.

[0140] In Table 2, the TIS for frequency band B8 (e.g., about 900 MHz) is 91 dB, and the TIS for frequency band B7 (e.g., about 2600 MHz) is 91 dB; thus, it can be seen that the receiving capability for frequency band B8 and the receiving capability for frequency band B7 are substantially the same. In contrast, for the TX0 antenna, the TRP for frequency band B8 is 14.5 dBm, and the TRP for frequency band B7 is 18.7 dBm; thus, it can be seen that the transmitting capability for frequency band B8 and the transmitting capability for frequency band B7 are different. As shown in Table 2, even if the receiving capabilities for the bands are substantially the same, the transmitting capabilities for the bands may differ.

[0141] As such, since transmission capability varies by frequency band, in situations where there is a relatively large amount of uplink data communication where transmission capability is particularly important, when two frequency bands have similar reception capabilities, deciding whether to perform a handover operation based solely on reception capability without considering transmission capability can lead to a degradation in overall performance.

[0142] Figure 6 is a diagram illustrating the overlap between the coverage of a serving base station and the coverage of an adjacent base station in a mobile communication system.

[0143] Referring to FIG. 6, the electronic device (101) (e.g., the electronic device (101) of FIG. 1, FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, or FIG. 3c) can enter an area (630) where the coverage of the serving base station (610) (e.g., serving cell) and the coverage of an adjacent base station (620) (e.g., adjacent cell) using frequency band B7 overlap, while the serving base station (610) is in a state of establishing a connection using frequency band B8.

[0144] For example, if A3-offset is set to 6 and hysteresis to 2 (A3-offset+hysteresis) / 2 = 4), the electronic device (101) may trigger event A3 when the signal strength (or power and / or quality) received from the adjacent base station (620) during TTT is greater than the signal strength received from the serving base station (610) by more than 4 dB, and an operation for handover may be performed in accordance with the triggering of event A3. However, since the transmission power for frequency band B7 is greater than the transmission power for frequency band B8 by more than 4 dB, when the signal strength received in frequency band B8 and the signal strength received in frequency band B7 are substantially the same, the electronic device (101) may have an advantage in terms of call connection or uplink throughput if it establishes a connection with the adjacent base station (620) using frequency band B7 rather than the serving base station (610).

[0145] Table 3 below may show the target transmission power for each frequency band of the electronic device (101), the maximum transmission power (e.g., Plimit) corresponding to the maximum value of the average specific absorption rate (e.g., Average SAR) that is set not to be exceeded during the set interval (e.g., Average SAR LIMIT), the TRP, the average TRP, the TRP swing per antenna, and the share. In Table 3 below, frequency bands B3 (e.g., B3: 1800 MHz+), B1 (e.g., 2100 MHz), B7 (e.g., 2600 MHz), and B40 (e.g., TD 2300 MHz), which belong to the middle band (MB) (e.g., a band from about 1 GHz to about 2 GHz) and high band (HB) (e.g., a band from about 2 GHz or higher), may have Plimit values ​​lower than the target transmit power to satisfy SAR specifications. This may indicate that the actual TRP may be smaller than the maximum TRP. Therefore, the electronic device (101) may need to determine whether to perform a handover operation based on the transmit capability as well as the receive capability.

In Table 3, the share for TX1 is expressed as "TX1 low" for Pmin.

[0157] Figure 7 is a diagram illustrating the overlap between the coverage of a serving base station and the coverage of an adjacent base station in a mobile communication system.

[0158] Referring to FIG. 7, an electronic device (101) (e.g., FIG. 1, FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, FIG. 3c, or FIG. 6) can enter an area (730) where the coverage of the serving base station (710) (e.g., the serving base station (610) of FIG. 6) (e.g., the serving cell) and the coverage of an adjacent base station (720) (e.g., the adjacent base station (620) of FIG. 6) (e.g., the adjacent cell) using frequency band B40 are overlapping while the serving base station (710) is in a state where the coverage of the serving base station (710) and the coverage of the adjacent base station (720) (e.g., the adjacent base station (620) of FIG. 6) (e.g., the adjacent cell) using frequency band B28 overlap.

[0159] For example, as illustrated in FIG. 7, when the electronic device (101) enters an area (730) where the coverage of the serving base station (710) and the coverage of the adjacent base station (720) overlap, it is assumed that the state of the bottom antenna of the electronic device (101) (e.g., antenna TX0) is in a grip state (e.g., a state where a user is holding the bottom antenna of the electronic device (101) with their hand), or that the electronic device (101) is fixed to another device such as a selfie stick, and that it is primarily performing uplink communication. Uplink communication may refer to a flow of data transmitted from the electronic device (101) to a base station or any other centralized device. Uplink communication may be used for the purpose of the electronic device (101) uploading data or reporting information. In the area (730) where the coverage of the serving base station (710) and the coverage of the adjacent base station (720) overlap, the electronic device (101) can confirm that the signal strength received from the serving base station (710) establishing a connection using frequency band B40 and the signal strength received from the adjacent base station (720) using frequency band B28 are substantially the same. For example, the RSRP of the signal received from the serving base station (710) may be about -100dBm, and the RSRP of the signal received from the adjacent base station (720) may be about -100dBm.

[0160] In this case, the difference between the transmission power for frequency band B40 and the transmission power for frequency band B28 may be about 6 dB, and thus it may be advantageous for the electronic device (101) to hand over to an adjacent base station (720) using frequency band B28. However, as described in FIG. 5, if the signal strength received from the adjacent base station during TTT is not greater than the signal strength received from the serving base station by more than 4 dB, event A3 may not be triggered, and thus the electronic device (101) may maintain a connection with the serving base station (710) without handing over to the adjacent base station (720). For example, a transmission power of about 6 dBm may be a transmission power level that can adjust the level of the modulation and coding scheme (MCS), which directly affects not only the call connection but also the throughput, and thus, the electronic device (101) not handing over to the adjacent base station (720) may result in a degradation in performance.

[0161] Meanwhile, in Table 3, the TRP swing value per antenna is the actual output TRP value when the electronic device (101) uses maximum transmission power, and can be fixed or swing according to the Plimit. The Plimit may represent the maximum transmission power corresponding to the maximum value of Average SAR (e.g., Average SAR LIMIT) that is set so as not to be exceeded during a set interval. To satisfy the SAR specification that limits SAR (or TAS), the transmission power can be adjusted in accordance with the Plimit. The electronic device (101) can swing the transmission power based on Pmax, which is the maximum value of the Plimit, and Pmin, which is the minimum value of the Plimit (e.g., Plimit-3dBm). For example, if the Plimit is smaller than Pmax, the maximum transmission power can swing, and the greater the difference between Pmax and Plimit, the shorter the output time of Pmax and the longer the output time of Pmin.

[0162] Figure 8 is a diagram illustrating the TRP swing for frequency band B5 in a mobile communication system.

[0163] Figure 9 is a diagram illustrating the TRP swing for frequency band B1 in a mobile communication system.

[0164] Referring to FIGS. 8 and 9, when frequency bands B5 and B1 are used in an electronic device (e.g., the electronic device (101) of FIG. 1, FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, FIG. 3c, FIG. 6, or FIG. 7) as described in Table 3, the TRP for TX0, which is an antenna located at the bottom of the electronic device among a plurality of antennas included in the electronic device, can swing. For example, frequency band B1 may be a frequency band used by a serving base station, and frequency band B5 may be a frequency band used by an adjacent base station.

[0165] As illustrated in FIGS. 8 and 9, the maximum TRP in frequency band B1 is about 2 dB higher than in frequency band B5, but the average TRP in frequency band B1 is about 2.5 dB lower than in frequency band B5, and the minimum TRP in frequency band B1 is about 5.5 dB lower than in frequency band B5. If the condition for triggering event A3 is that the difference between the signal strength (or power and / or quality) received from the serving base station and the signal strength received from the adjacent base station is 4 dB, then in the situation described in FIGS. 6 and 7, the electronic device may not hand over to the adjacent base station using frequency band B5. In this case, when the electronic device is performing uplink transmission at a relatively high transmission rate, handing over to the adjacent base station using frequency band B5 may be advantageous in terms of data transmission speed, and the call connection can also be maintained stably. For example, the area where the coverage of a serving base station and the coverage of an adjacent base station overlap may be a weak field area, and for frequency band B1 in this overlap area, 10.5 dBm, which is 7.5 dB lower than the maximum transmit power, is used for 80% of the set period, which may not only cause degradation of uplink throughput but also cause deterioration of call quality, call drop, and / or RLF.

[0166] Figure 10 is a diagram illustrating the TRP swing for frequency band B3 in a mobile communication system.

[0167] Figure 11 is a diagram illustrating the TRP swing for frequency band B4 in a mobile communication system.

[0168] Figure 12 is a diagram illustrating the TRP swing for frequency band B28 in a mobile communication system.

[0169] Figure 13 is a diagram illustrating the TRP swing for frequency band B40 in a mobile communication system.

[0170] Referring to FIGS. 10, 11, 12, and 13, as illustrated in FIGS. 10 and 11, the average transmission power (Plimit), maximum transmission power (Pmax), minimum transmission power (Pmin), and occupancy rate when an electronic device (e.g., the electronic device (101) of FIG. 1, 2a, 2b, 3a, 3b, 3c, 6, or 7) uses frequency band B3 may show a relatively large difference from the average transmission power (Plimit), maximum transmission power (Pmax), minimum transmission power (Pmin), and occupancy rate when the electronic device uses frequency band B4. In this case, the electronic device may determine the handover between frequency bands by taking TRP into account.

[0171] In contrast, as illustrated in FIGS. 12 and 13, when an electronic device uses frequency band B28, the average transmission power (Plimit), maximum transmission power (Pmax), minimum transmission power (Pmin), and occupancy rate may be similar to when an electronic device uses frequency band B40. For example, for frequency band B28, the Plimit is greater than Pmax, so the electronic device may use a fixed Pmax, for example, 14.4 dBm, without swinging the TRP, and for frequency band B40, the electronic device may swing the TRP between Pmax of 19.4 dBm and Pmin of 11.4 dBm, taking into account the Plimit of 14.4 dBm. As explained above, in mobile communication systems, even though an electronic device has relatively superior transmission capabilities (e.g., transmission power), determining whether to perform a handover operation based solely on reception capabilities (e.g., reception strength) can lead to degradation in the performance of the electronic device.

[0172] Accordingly, the present disclosure may provide an electronic device and a method of operation thereof for determining whether to perform a handover operation based on both receiving capability and transmitting capability.

In one embodiment, the measurement configuration may include a measurement period during which the measurement operation is to be performed, information related to the measurement targets on which the measurement operation is to be performed, and reporting conditions for reporting the results of the measurement operation to a serving base station. For example, the measurement configuration message may be implemented similarly or substantially identically to the MeasConfig information element (IE) included in the radio resource control (RRC) connection reconfiguration (RRCConnectionReconfiguration) message of V18.2.0 of 3GPP TS 36.331, and thus redundant descriptions may be omitted.

[0202] An electronic device that receives a measurement configuration message from a serving base station may, in operation 1413, perform a measurement operation for the serving base station and an adjacent base station based on the measurement configuration message. For example, in operation 1413, the electronic device may, based on information related to the measurement period and measurement targets included in the measurement configuration message, perform a measurement operation for the serving base station and an adjacent base station.

[0203] An electronic device that performs a measurement operation for a serving base station and an adjacent base station based on a measurement configuration message can determine in operation 1415 that the signal strength (or power and / or quality) received from the serving base station is a first value and the signal strength received from the adjacent base station is a second value. For example, the received signal strength may include RSRP and / or RSRQ.

[0204] An electronic device that has confirmed that the signal strength received from a serving base station is a first value and the signal strength received from an adjacent base station is a second value can, in operation 1417, determine whether a condition indicating that the transmission capability of the electronic device to an adjacent base station (or transmission capability associated with an adjacent base station) is superior to the transmission capability of the electronic device to a serving base station (or transmission capability associated with a serving base station) is satisfied based on information associated with a first frequency band used by the serving base station, transmission power for the first frequency band, a second frequency band used by the adjacent base station, and transmission power for the second frequency band, which is stored in advance in memory (e.g., memory (130) of FIG. 1, FIG. 2a, or FIG. 2b). In one embodiment, the information associated with the first frequency band used by the serving base station, transmission power for the first frequency band, the second frequency band used by the adjacent base station, and transmission power for the second frequency band may be implemented in the form of a table. For example, information related to a first frequency band used at a serving base station, transmission power for the first frequency band, a second frequency band used at an adjacent base station, and transmission power for the second frequency band can be implemented in the form of a table as shown in Table 3. In one embodiment, the transmission capability of the electronic device to the serving base station and the transmission capability of the electronic device to the adjacent base station can be determined based on the antenna currently being used by the electronic device among a plurality of antennas included in the electronic device.

[0205] In one embodiment, a condition indicating that the transmission capability of an electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station may include a condition in which the maximum transmission power of the electronic device for a second frequency band used by the adjacent base station is greater than or equal to a first threshold value than the maximum transmission power of the electronic device for a first frequency band used by the serving base station.

[0206] In one embodiment, the transmission capability of the electronic device to a serving base station may be determined based on a first maximum value and a first minimum value of a Plimit for a first frequency band corresponding to an Average SAR limit. In one embodiment, the first maximum value may include the maximum transmission power of the electronic device for the first frequency band that is applied when a back-off operation to satisfy conditions associated with TAS is not performed, and the first minimum value may include the minimum transmission power of the electronic device for the first frequency band that is applied when a back-off operation is performed. In one embodiment, the transmission capability of the electronic device to an adjacent base station may be determined based on a second maximum value and a second minimum value of a Plimit for a second frequency band corresponding to an Average SAR limit. In one embodiment, the second maximum value may include the maximum transmission power of the electronic device for the second frequency band that is applied when a back-off operation is not performed, and the second minimum value may include the minimum transmission power of the electronic device for the second frequency band that is applied when a back-off operation is performed.

[0207] In one embodiment, the electronic device can confirm that a condition indicating that the transmission capability of the electronic device to the adjacent base station is superior to the transmission capability of the electronic device to the serving base station is satisfied when the maximum transmission power of the electronic device for the second frequency band used by the adjacent base station is greater than or equal to a second threshold value than the maximum transmission power of the electronic device for the first frequency band used by the serving base station.

[0208] In one embodiment, the electronic device determines a first weight based on a first maximum value, a first minimum value, a second maximum value, and a second minimum value, determines a fifth value by applying the first weight to the second value, determines a sixth value by applying a second weight based on a reporting condition to the first value, and can determine whether a condition indicating that the transmission capability of the electronic device toward an adjacent base station is superior to the transmission capability of the electronic device toward a serving base station is satisfied based on the fifth value and the sixth value.

[0209] In one embodiment, the electronic device can determine a first share of a section in which a first maximum value is maintained among additional sections that are the same as or different from a set section, a second share of a section in which a first minimum value is maintained among additional sections, a third share of a section in which a second maximum value is maintained among additional sections, and a fourth share of a section in which a second minimum value is maintained among additional sections, and determine a first weight based on the first share, the second share, the third share, and the fourth share.

[0210] As a result of checking whether the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is satisfied, if the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is satisfied (Operation 1417-Yes), the electronic device may, in Operation 1419, change the measured value of the signal strength received from the adjacent base station to a third value greater than the second value. If the transmission performance of the electronic device to an adjacent base station is superior to the transmission performance of the electronic device to a serving base station, it may be advantageous in terms of performance for the electronic device to perform a handover even if the signal strength received from the serving base station is greater than the signal strength received from the adjacent base station. Therefore, in order to increase the probability of handover from the serving base station to the adjacent base station, the electronic device may change the signal strength received from the adjacent base station to a third value greater than the second value, which is the actual measured value obtained by performing a measurement operation.

[0211] An electronic device that changes the measured value of the signal strength received from an adjacent base station to a third value greater than the second value can, in operation 1421, check whether the reporting condition for transmitting a measurement report message is satisfied. For example, in operation 1421, the electronic device can check whether the reporting condition for transmitting a measurement report message is satisfied based on the first value and the third value. In one embodiment, the reporting condition may include an event that triggers a measurement report, and the event that triggers the measurement report may include events A1 through A6, event B1, and event B2. For example, the event that triggers the measurement report may be event A3. Event A3 may be implemented similarly or substantially identically to that described in Equation 1, and thus redundant description may be omitted. Events A1 through A6, Event B1, and Event B2 may be implemented similarly or substantially identically to Events A1 through A6, Event B1, and Event B2 specified in V18.2.0 of 3GPP TS 36.331, and thus redundant descriptions may be omitted.

[0212] If, as a result of checking whether the reporting conditions for transmitting a measurement report message are satisfied based on the first and third values, the reporting conditions for transmitting a measurement report message are not satisfied (operation 1421-No), the electronic device may terminate without performing any further operations.

[0213] As a result of checking whether the reporting conditions for transmitting a measurement report message are satisfied based on the first value and the third value, if the reporting conditions for transmitting a measurement report message are satisfied (Operation 1421-Yes), the electronic device may, in Operation 1423, transmit a measurement report message including the identifier of an adjacent base station and the third value to a serving base station through a communication circuit. The measurement report message may be implemented similarly or substantially identically to the Measurement Report message of V18.2.0 of 3GPP TS 36.331, and thus redundant description may be omitted.

[0214] Alternatively, if the condition indicating that the electronic device’s transmission capability to an adjacent base station is superior to the electronic device’s transmission capability to a serving base station is not satisfied (Operation 1417-No), the electronic device may, in Operation 1425, check whether the condition indicating that the electronic device’s transmission capability to a serving base station is superior to the electronic device’s transmission capability to an adjacent base station is satisfied.

[0215] If a condition is satisfied indicating that the transmission capability of the electronic device to the serving base station is superior to the transmission capability of the electronic device to the adjacent base station (Operation 1425-Example), the electronic device may, in Operation 1427, change the measured value of the signal strength received from the serving base station to a fourth value greater than the first value.

[0216] If the transmission performance of the electronic device to the serving base station is superior to the transmission performance of the electronic device to the adjacent base station, it may be advantageous in terms of performance for the electronic device not to perform a handover, even if the signal strength received from the adjacent base station is greater than the signal strength received from the serving base station. Therefore, to reduce the probability of handover from the serving base station to the adjacent base station, the electronic device may change the measured value of the signal strength received from the serving base station to a fourth value that is greater than the first value, which is the actual measured value obtained by performing a measurement operation.

[0217] An electronic device that changes the measured value of the signal strength received from a serving base station to a fourth value greater than the first value can proceed to operation 1421 and perform subsequent procedures. For example, in operation 1421, the electronic device checks whether a reporting condition for transmitting a measurement report message is satisfied based on the fourth value and the second value, and if the reporting condition is satisfied, in operation 1423, it can transmit a measurement report message including the identifier of an adjacent base station and the second value to the serving base station.

[0218] If the condition indicating that the transmission capability of the electronic device to the serving base station is superior to the transmission capability of the electronic device to the adjacent base station is not satisfied (Operation 1425-No), the electronic device may proceed to Operation 1421 and perform subsequent procedures. For example, in Operation 1421, the electronic device may check whether the reporting condition for transmitting a measurement report message is satisfied based on the first value and the second value, and if the reporting condition is satisfied, in Operation 1423, transmit a measurement report message including the identifier of the adjacent base station and the second value to the serving base station.

[0219] Although operations 1425 and 1427 in FIG. 14 describe the operation of adjusting the measured value of the signal strength received from the serving base station, operations 1425 and 1427 may be omitted in situations where the electronic device needs to consider the signal strength received from other adjacent base stations other than the serving base station and the adjacent base station, because changing the measured value of the signal strength received from the serving base station may affect the operation of other adjacent base stations. If operations 1425 and 1427 are omitted, if the condition indicating that the electronic device’s transmission capability toward an adjacent base station is superior to the electronic device’s transmission capability toward a serving base station is not satisfied as a result of checking in operation 1417, the electronic device proceeds to operation 1421 to check whether a reporting condition for transmitting a measurement report message is satisfied based on a first value, which is a measurement value of the signal strength received from the serving base station, and a second value, which is a measurement value of the signal strength received from the adjacent base station. If the reporting condition is satisfied, in operation 1423, the electronic device can transmit a measurement report message to the serving base station that includes the identifier of the adjacent base station and the measurement value of the signal strength received from the adjacent base station.

[0220] Although not separately illustrated in FIG. 14, the electronic device, after transmitting a measurement report message, receives a handover command message in response to the measurement report message from a serving base station via a communication circuit, and based on receiving the handover command message, can perform an operation for handover from the serving base station to an adjacent base station. The handover command message and the operation for handover from the serving base station to an adjacent base station can be implemented similarly or substantially identically to the handover command message and handover operation of V18.2.0 of 3GPP TS 36.331, and thus redundant descriptions may be omitted.

[0221] FIG. 15 is a flowchart illustrating the operation process of an electronic device according to one embodiment.

[0222] In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0223] Referring to FIG. 15, an electronic device (101) (e.g., the electronic device (101) of FIG. 1, FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, FIG. 3c, FIG. 6, and / or FIG. 7) (e.g., one or more processors including processing circuitry) (e.g., the processor (120) of FIG. 1, FIG. 2a, or FIG. 2b, the first communication processor (212) or the second communication processor (214) of FIG. 2a, and / or the integrated communication processor (260) of FIG. 2b) may, in operation 1511, perform a measurement operation for a serving base station and an adjacent base station based on a measurement configuration message received from a serving base station. For example, in operation 1511, the electronic device may, based on information related to the measurement cycle and measurement targets included in the measurement configuration message, perform a measurement operation for a serving base station and an adjacent base station. An electronic device that performs a measurement operation for a serving base station and an adjacent base station can confirm that the signal strength received from the serving base station is a first value and the signal strength received from the adjacent base station is a second value. For example, the signal strength may include RSRP and / or RSRQ. The measurement operation of operation 1511 may be implemented similarly or substantially identically to the measurement operation of operation 1413 of FIG. 14, and thus redundant description may be omitted.

[0224] An electronic device that performs a measurement operation for a serving base station and an adjacent base station based on a measurement configuration message may, in operation 1513, check the antenna currently in use (e.g., a transmitting antenna) and the usage conditions. In one embodiment, the electronic device may include a plurality of antennas and may be currently performing communication using any one of these antennas. In one embodiment, the reason the electronic device checks the antenna currently in use among the plurality of antennas may be that even within the same frequency band, the Plimit, TRP, average TRP, Pmax, and occupancy rates differ depending on the characteristics of the antennas. In one embodiment, the usage conditions may include the current state of the antenna, e.g., a grip state or a free state, and / or whether a USB cable is inserted into the electronic device.

[0225] An electronic device that has verified the transmitting antenna currently in use and the usage conditions can, in operation 1515, verify whether a condition indicating that the transmitting capability of the electronic device to an adjacent base station is superior to the transmitting capability of the electronic device to a serving base station is satisfied. In one embodiment, the condition indicating that the transmitting capability of the electronic device to an adjacent base station is superior to the transmitting capability of the electronic device to a serving base station may be as follows.

[0226] (A) The electronic device has an average TRP of +1dB relative to adjacent base stations. It is possible to check whether the average TRP is for the serving base station. Figure 15 describes an example in which the electronic device checks whether the average TRP for an adjacent base station is greater than the average TRP for the serving base station by more than 1 dBm, but 1 dBm can be set to a different value depending on the performance and circumstances of the electronic device.

[0227] (B) Average TRP +1dB for adjacent base stations In the case of the average TRP for the serving base station, the electronic device can check the value of S (e.g., (((3)-(1))*a + ((1)-(4))*b + ((4)-(2))*c) / 2) if the Pmax for the serving base station during the setting period is greater than or equal to the Pmax for the adjacent base station, and check the value of N (e.g., (((3)-(1))*a + ((3)-(2))*b + ((4)-(2))*c) / 2) if the Pmax for the adjacent base station during the setting period is greater than or equal to the Pmax for the serving base station. Here, (1) represents the TRPmax for the serving base station, (2) represents the TRPmin for the serving base station, (3) represents the TRPmax for the adjacent base station, (4) represents the TRPmin for the adjacent base station, a represents the smaller share of (1) and (3) during the setting period, b represents the value obtained by subtracting the smaller share from the larger share of (1) and (3) during the setting period, and c represents 1 - (the larger share of (1) and (3)). In one embodiment, the maximum value of S or N may be limited to, for example, 3 dB. The reason for limiting the maximum value of S or N in this way is that if the weighting for the transmission capability of the electronic device is set excessively high, the reception capability of the electronic device may be inaccurately considered, making normal handover impossible. Therefore, the maximum value of S or N may be determined by considering various parameters depending on the performance and situation of the electronic device.

[0228] (C) If S or N is 0 or greater (S 0 or N (in the case of 0), the electronic device can check whether the RSRP + (S or N) of the signal received from the adjacent base station exceeds the RSRP + (A3-offset+hysteresis) / 2 of the signal received from the serving base station (Neighbor cell RSRP + (S or N) > serving cell RSRP + (A3-offset+hysteresis) / 2). Here, Neighbor cell RSRP represents the RSRP of the signal received from the adjacent base station, serving cell RSRP represents the RSRP of the signal received from the serving base station, A3-offset represents the offset applied to event A3, and hysteresis represents the hysteresis parameter applied to event A3. A3-offset and hysteresis can be set by the serving base station. For example, (A3-offset+hysteresis) / 2 can be set to about 2 to 5 dB. If Neighbor cell RSRP + (S or N) > serving cell RSRP + (A3-offset+hysteresis) / 2, it can be confirmed that the condition indicating that the electronic device’s transmission capability toward the neighboring base station is superior to the electronic device’s transmission capability toward the serving base station is satisfied. Alternatively, if the average TRP for the neighboring base station + 1dB is greater than the average TRP for the serving base station by 3dB or more, which is the maximum value of S or N, it can be confirmed that the electronic device’s transmission capability toward the neighboring base station is superior to the electronic device’s transmission capability toward the serving base station is satisfied, without considering the share of Pmax for the serving base station, the share of Pmin for the serving base station, the share of Pmax for the neighboring base station, and the share of Pmin for the neighboring base station during the set interval.

[0229] As a result of checking whether the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is satisfied, if the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is satisfied (Operation 1515-Yes), the electronic device may, in Operation 1517, change the measured value of the signal strength received from the adjacent base station to a third value greater than the second value. For example, the third value may be a value obtained by adding a weight to the second value. For example, the weight may be set to a value of ((Average TRP for adjacent base station +1dB) - (Average TRP for serving base station)) / 2. Alternatively, if the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is not satisfied (Operation 1515-No), the electronic device may proceed to Operation 1519.

[0230] An electronic device that changes the measured value of the signal strength received from an adjacent base station to a third value greater than the second value can, in operation 1519, check whether the reporting condition for transmitting a measurement report message is satisfied. For example, in operation 1519, the electronic device can check whether the reporting condition for transmitting a measurement report message is satisfied based on the first value and the third value. In one embodiment, the reporting condition may include an event that triggers a measurement report, and the event that triggers the measurement report may include events A1 through A6, event B1, and event B2. For example, the event that triggers the measurement report may be event A3. Event A3 may be implemented similarly or substantially identically to that described in Equation 1, and thus the redundant description may be omitted. Events A1 through A6, Event B1, and Event B2 may be implemented similarly or substantially identically to Events A1 through A6, Event B1, and Event B2 specified in V18.2.0 of 3GPP TS 36.331, and thus redundant descriptions may be omitted.

[0231] If, as a result of checking whether the reporting conditions for transmitting a measurement report message are satisfied based on the first and third values, the reporting conditions for transmitting a measurement report message are not satisfied (Operation 1519-No), the electronic device may terminate without performing any further operations.

[0232] As a result of checking whether the reporting conditions for transmitting a measurement report message are satisfied based on the first value and the third value, if the reporting conditions for transmitting a measurement report message are satisfied (Operation 1519-Yes), the electronic device may, in Operation 1521, transmit a measurement report message including the identifier of an adjacent base station and the third value to a serving base station through a communication circuit. The measurement report message may be implemented similarly or substantially identically to the Measurement Report message of V18.2.0 of 3GPP TS 36.331, and thus redundant description may be omitted.

[0233] FIG. 16 is a flowchart illustrating the operation process of an electronic device according to one embodiment.

[0234] In the following embodiments, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed, and at least two operations may be performed in parallel.

[0235] Referring to FIG. 16, an electronic device (101) (e.g., the electronic device (101) of FIG. 1, FIG. 2a, FIG. 2b, FIG. 3a, FIG. 3b, FIG. 3c, FIG. 6, and / or FIG. 7) (e.g., one or more processors including processing circuitry) (e.g., the processor (120) of FIG. 1, FIG. 2a, or FIG. 2b, the first communication processor (212) or the second communication processor (214) of FIG. 2a, and / or the integrated communication processor (260) of FIG. 2b) can analyze a communication environment in operation 1611. In one embodiment, the electronic device can collect analysis parameters used to analyze the communication environment of the electronic device. For example, analysis parameters may include the cell identifier of the serving base station to which the electronic device is connected, GPS information, RSRP, RSRQ, RLF information (e.g., an RLF count indicating the number of times an RLF occurred), throughput before the electronic device performs a handover and throughput after the electronic device performs a handover, and / or parameters that can be collected over a relatively long period (e.g., one week), such as weather, and / or parameters that can be collected over a relatively short period, such as the current consumption of the electronic device, whether a voice call is performed on the electronic device, the amount of data transmitted, and / or location information of the electronic device, such as indoor / outdoor / in-vehicle. In one embodiment, the communication environment analysis may be performed on the electronic device or on a server (e.g., a cloud server). If the communication environment analysis is performed on a server, the electronic device may transmit analysis parameters to the server so that the server analyzes the communication environment of the electronic device using the analysis parameters received from the electronic device.

[0236] The server can predict the location of the handover and the frequency band used before and after the handover by using various artificial intelligence (AI) models, by analyzing the handover location in the weak field overlap area where the handover occurs, the reception capability at the time of the handover, and / or the throughput before and after the handover based on analysis parameters. The server can obtain the inference results of the AI ​​model by applying the analysis parameters to the AI ​​model. In one embodiment, parameters that can be collected over a relatively long period, such as the cell identifier of the serving base station connected to the electronic device, GPS information, RSRP, RSRQ, RLF information, the throughput before the electronic device performs the handover, the throughput after the electronic device performs the handover, and / or weather, may be parameters related to the capability of the electronic device, and parameters that can be collected over a relatively short period, such as the current consumption of the electronic device, whether a voice call is performed on the electronic device, the amount of data transmitted, and / or location information of the electronic device, such as indoor / outdoor / in-vehicle, may be used as information to compensate for the parameters related to the capability of the electronic device.

[0237] An electronic device that has analyzed the communication environment may, in operation 1613, determine whether the serving base station to which the electronic device is currently connected is included in the analyzed communication environment. If the serving base station to which the electronic device is currently connected is not included in the analyzed communication environment (operation 1613-No), the electronic device may terminate without performing any further operations.

[0238] If the currently connected serving base station is included in the analyzed communication environment (Operation 1613-Yes), the electronic device may perform a measurement operation in Operation 1615. Operation 1615, which performs the measurement operation, may be implemented similarly or substantially identically to Operation 1413 of FIG. 14, and thus redundant descriptions may be omitted.

[0239] The electronic device performing the measurement operation can determine whether the condition indicating that the electronic device’s transmission capability to an adjacent base station is superior to the electronic device’s transmission capability to a serving base station is satisfied in operation 1617. Operation 1617, which determines whether the condition indicating that the electronic device’s transmission capability to an adjacent base station is superior to the electronic device’s transmission capability to a serving base station is satisfied, can be implemented similarly or substantially identically to operation 1417 of FIG. 14, and thus redundant descriptions may be omitted.

[0240] If a condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is satisfied (Operation 1617-Yes), the electronic device may, in Operation 1619, check whether the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is satisfied based on the location of the electronic device. In one embodiment, the electronic device may check whether the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is satisfied based on whether the location of the electronic device corresponds to a location where the amount of real-time data transmission and reception is relatively large, such as an urban environment where buildings are dense and there are relatively many users, or a location where the communication environment changes even within the same location, such as rain or snow. In one embodiment, if the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station is not satisfied (Operation 1617-No), the electronic device may proceed to Operation 1623.

[0241] If a condition is satisfied indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station based on the location of the electronic device (Operation 1619-Yes), the electronic device may, in Operation 1621, change the measured value of the signal strength received from the adjacent base station to a third value greater than the second value. Operation 1621 of changing the measured value of the signal strength received from the adjacent base station may be implemented similarly or substantially identically to Operation 1419 of FIG. 14, and thus redundant description thereof may be omitted.

[0242] An electronic device that has changed the measured value of the signal strength received from an adjacent base station can, in operation 1623, check whether the reporting condition for transmitting a measurement report message is satisfied. For example, in operation 1623, the electronic device can check whether the reporting condition for transmitting a measurement report message is satisfied based on a first value and a third value. Operation 1623, which checks whether the reporting condition for transmitting a measurement report message is satisfied, can be implemented similarly or substantially identically to operation 1421 of FIG. 14, and thus redundant description may be omitted.

[0243] If the reporting condition is satisfied (Operation 1623-Yes), the electronic device may, in Operation 1625, transmit a measurement report message containing the identifier of an adjacent base station and a third value to a serving base station via a communication circuit. Operation 1625 of transmitting the measurement report message may be implemented similarly or substantially identically to Operation 1423 of FIG. 14, and thus redundant description thereof may be omitted. If the reporting condition is not satisfied (Operation 1623-No), the electronic device may terminate without performing any further operations.

[0244] If, as a result of checking in Operation 1619, the condition indicating that the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station based on the location of the electronic device is not satisfied (Operation 1619-No), the electronic device may, in Operation 1627, change the measured value of the signal strength received from the adjacent base station to a fourth value greater than the second value. However, the fourth value may be set to a value smaller than the third value, and the reason may be that although the transmission capability of the electronic device to an adjacent base station is superior to the transmission capability of the electronic device to a serving base station, the location of the electronic device is not based on a location where the probability of a handover being performed is high, inferred through an AI model.
