Description

Electronic device for controlling antenna settings and operating method thereof {ELECTRONIC DEVICE FOR CONTROLLING ANTENNA SETTING AND OPERATING METHOD THEREOF}

This disclosure relates to an electronic device that controls antenna settings and a method of operating the same.

Recently, as the use of portable terminals that provide various functions has become widespread due to the development of mobile communication technology, efforts have been made to develop a ^5th generation (5G) communication system to meet the increasing demand for wireless data traffic. This is being done. The 5G communication system is used in the 3rd generation (5 ^rd generation: 3G) communication system and the long term evolution (LTE) communication system to achieve a high data rate and provide faster data transmission speed. In addition to the frequency band, implementation in higher frequency bands (e.g., 25-60 GHz band) is being considered.

For example, in order to mitigate the path loss of radio waves and increase the transmission distance of radio waves in the millimeter wave (mmWave) band, the 5G communication system uses beamforming technology, massive multiple input, multiple output. -input multiple-output: MIMO) technology, full dimensional MIMO (FD-MIMO) technology, array antenna technology, analog beamforming technology, and large scale antenna technology. This is being discussed.

Electronic devices are simplified for 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 antenna's transmission power can be increased to improve the antenna's transmission performance. The specific absorption rate (SAR) is a value that indicates the degree to which electromagnetic waves generated in this way are absorbed by the human body, and there may be cases where the transmission power of an electronic device is limited to satisfy regulatory standards for SAR.

The electronic device may include a grip sensor, and the grip sensor may be used to sense changes in electric charge of a metal part of the antenna and may recognize the approach of a dielectric such as the human body. When the grip sensor recognizes the approach of a human body, the transmission power of the signal transmitted from the electronic device can be maintained at a level that can satisfy regulatory standards for SAR.

For an electronic device to transmit signals to a communications network (e.g., a base station), the processor within the electronic device, or data generated from the communications processor, uses a radio frequency integrated circuit (RFIC), a radio frequency front end. front end: RFFE), and may be processed through an antenna tuning circuit and then transmitted through at least one antenna.

When a dielectric approaches at least one antenna, the impedance of at least one antenna may change, which may cause radio frequency (RF) performance to deteriorate. Electronic devices are using antenna tuning circuits to improve RF performance in a variety of scenarios. In this case, the electronic device can recognize the approach of the dielectric to the antenna through the grip sensor and operate the antenna tuning circuit to alleviate RF performance degradation due to the approach of the dielectric.

Because the grip sensor consumes current when turned on, the electronic device must determine the state of the electronic device (e.g. radio resource control (RRC) idle (RRC_IDLE) state, RRC). The grip sensor can be turned on or turned off depending on the inactive (RRC_INACTIVE) state or the RRC connected (RRC_CONNECTED) state. To prevent current consumption due to turning on the grip sensor, the electronic device turns off the grip sensor when the state of the electronic device is RRC_IDLE or RRC_INACTIVE, and turns on the grip sensor when the state of the electronic device is RRC_CONNECTED. It can be turned on.

In this way, when the state of the electronic device is RRC_IDLE state or RRC_INACTIVE state, the grip sensor may be turned off. Therefore, the electronic device may not be able to operate the antenna tuning circuit based on the proximity of the dielectric sensed by the grip sensor, which may result in performance degradation for receiving operations of the electronic device, such as receiving a call signal. In addition, performance degradation in the transmission operation of the electronic device may also occur, such as when a random access procedure is performed in the RRC_IDLE state of the electronic device.

For example, in a 5G network, there is only an access network (e.g., 5G radio access network (RAN) or next generation RAN (NG RAN)) and a core network (e.g., next generation core). : NGC)) may not exist. In this case, the electronic device 101 accesses the access network of the 5G network and then accesses the external network (e.g., the Internet) under the control of the core network (e.g., evolved packet core (EPC)) of the legacy network.

According to an embodiment of the present disclosure, the random access preamble signal may be transmitted a set number of times until the RAR signal is received. FIG. 6 is a flowchart illustrating a method of operating an electronic device, according to an embodiment. .

Referring to FIG. 6, an electronic device (e.g., the electronic device 101 of FIGS. 1, 2A, 2B, 3A to 3C, or FIG. 4) (e.g., the processor 120 of FIG. 1, the electronic device 101 of FIG. 2A) The first communication processor 212 or the second communication processor 214, or the integrated communication processor 260 of FIG. 2B or FIG. 4) may transition to the RRC_IDLE state or the RRC_INACTIVE state at operation 611. In one embodiment, when the electronic device transitions to the RRC_IDLE state or the RRC_INACTIVE state, the electronic device may turn off the grip sensor (e.g., the grip sensor 410 in FIG. 4).

The electronic device that has transitioned to the RRC_IDLE state or the RRC_INACTIVE state, in operation 613, includes at least one antenna tuning circuit corresponding to a grip sensor (e.g., grip sensor 410 in FIG. 4) prior to transitioning to the RRC_IDLE state or the RRC_INACTIVE state. The first setting value, which is the setting value of the antenna tuning circuit 440 of FIG. 4 or FIG. 5, may be maintained. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates a grip touch state, the first setting value is at least one antenna tuning connected to at least one antenna (e.g., antenna 460 in FIG. 4). With respect to the frequency used in the RF circuit including the circuit (e.g., the RF circuit 450 in FIG. 5), it may be a setting value used by at least one antenna tuning circuit when in a grip state. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates the grip release state, the first setting value is for the frequency used in the RF circuit, and when in the free space state, is used by at least one antenna tuning circuit. It may be a set value.

In operation 615, the electronic device may transmit a first signal for random access to the base station based on the first transmission power and the first setting value. In one embodiment, the electronic device may control the RF circuit to transmit the first signal for random access based on the first transmission power and the first setting value. In one embodiment, the first signal may include a random access preamble signal. In one embodiment, the first signal may include a random access preamble signal and data by the first scheduled transmission of the random access procedure. In one embodiment, when an electronic device performs a 4-step random access procedure, the first signal may include a random access preamble signal. In one embodiment, when an electronic device performs a 2-step random access procedure, the first signal may include a random access preamble signal and data by first scheduled transmission. In one embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number indicated by the parameter preambleTransMax) until the second signal is received. In one embodiment, the parameter preambleTransMax may indicate the maximum number of first signal transmissions performed before failure for the random access procedure is declared. Accordingly, operation 615 may be performed only until the maximum number of first signal transmissions is reached. In one embodiment, the second signal may be a response signal to the first signal. In one embodiment, the second signal may include a random access response (RAR) signal. In one embodiment, the second signal may include a RAR signal and contention resolution. In one embodiment, when the electronic device performs a 4-step random access procedure, the second signal may include a RAR signal. In one embodiment, when the electronic device performs a two-step random access procedure, the second signal may include a RAR signal and contention resolution.

In operation 617, the electronic device can check whether a second signal is received from the base station in response to the first signal. In one embodiment, the electronic device may check whether a second signal is received in response to the first signal through an RF circuit. In one embodiment, the electronic device determines whether a second signal is received in response to the first signal via the RF circuitry within a set time period (e.g., the time period indicated by the parameter ra-ResponseWindow). You can. In one embodiment, the parameter ra-ResponseWindow may indicate the Msg2 (RAR) window length indicated by the network, and the Msg2 (RAR) window length corresponds to a set number of slots, as an example. It can be a period of time.

If the second signal is not received as a result of the check in operation 617, the electronic device can check whether the set condition is satisfied in operation 619. In one embodiment, the set condition may include a condition where the first transmit power is equal to the threshold transmit power. The threshold transmission power may include the maximum transmission power (Max Tx power) that the electronic device can use to transmit the first signal.

As a result of the confirmation in operation 619, if the set condition is satisfied, the electronic device may change the setting value from the first setting value to the second setting value in operation 621. In one embodiment, the second setting value may be a setting value other than the first setting value among setting values that can be set for the frequency used in the RF circuit (eg, a first setting value and a second setting value). In one embodiment, the second set value may be a set value for a frequency used in the RF circuit that is set to correspond to a second state that is different from the first state of the grip sensor corresponding to the first set value. In one embodiment, the second signal is transmitted in response to the first signal even though a set condition is met (e.g., despite transmitting the first signal using a threshold transmit power (e.g., maximum transmit power)). Cases where reception is not possible may include cases where antenna radiation performance is deteriorated due to decreased antenna efficiency. If antenna efficiency decreases, the antenna's radiation performance may deteriorate, which may result in a decrease in total radiated power (TRP) performance and/or a decrease in total isotropic sensitivity (TIS) performance. may result in Therefore, according to one embodiment, antenna efficiency can be improved by changing the setting value (eg, tuning value) used in the antenna tuning circuit from the first setting value to the second setting value. In this way, as antenna efficiency is improved, the radiation performance of the antenna can be improved, and thus TRP performance and/or TIS performance can also be improved. In this way, as TRP performance improves, when the electronic device transmits the first signal based on the first transmission power and the second setting value, the electronic device transmits the first signal based on the first transmission power and the first setting value. Compared to the case of transmitting, the probability that the first signal will reach (receive) the base station may be increased.

In operation 623, the electronic device may transmit the first signal to the base station based on the first transmission power and the second set value. In one embodiment, the electronic device may control the RF circuit to transmit the first signal based on the first transmission power and the second set value.

In FIG. 6 , the operation of the electronic device in the RRC_IDLE state or RRC_INACTIVE state is explained by taking as an example the operation when the electronic device performs a random access procedure. An electronic device in the RRC_CONNECTED state may also operate in a similar manner as described in FIG. 6 when performing a random access procedure. Since the electronic device is in the RRC_CONNECTED state, operations 611 and 613 can be omitted. As operations 611 and 613 are omitted, the first setting value of operation 615 is at least at the time of transmitting the first signal, which is not the setting value of at least one antenna tuning circuit before transitioning to the RRC_IDLE state or the RRC_INACTIVE state. This can be the setting value of one antenna tuning circuit. Accordingly, when an electronic device in the RRC_CONNECTED state performs a random access procedure, operations may be similar or substantially the same as operations 615 to 623.

FIG. 7 is a diagram illustrating setting values used to control an antenna tuning circuit, according to an embodiment.

Referring to FIG. 7, the antenna (e.g., antenna 460 of FIG. 4) of an electronic device (e.g., the electronic device 101 of FIGS. 1, 2a, 2b, 3a to 3c, or FIG. 4) When a dielectric approaches, the impedance of the antenna may change, which may degrade RF performance. Due to this decrease in RF performance, antenna efficiency for each frequency may also decrease. To compensate for this decrease in antenna efficiency, the setting value (e.g., tuning value) of the antenna tuning circuit (e.g., the antenna tuning circuit 440 of FIG. 4) may be changed.

Reference number 711 is a graph showing the change in antenna efficiency in the free space state, reference number 713 is a graph showing the change in antenna efficiency in the grip state, and reference number 715 is a graph showing the change in antenna efficiency based on the tuning value in the grip state. This is a graph showing the change.

As shown in FIG. 7, in the case of a grip state due to the approach of the dielectric, the antenna efficiency for each frequency of the electronic device may change, and therefore the antenna efficiency at the target frequency (Target freq.) may also change. there is.

If antenna efficiency decreases, the radiation performance of the antenna may decrease. Degradation of the antenna's radiation performance may result in a decrease in total radiated power (TRP) performance and/or a decrease in total isotropic sensitivity (TIS) performance. In one embodiment, TRP performance may be related to the transmitting performance of the electronic device, and TIS performance may be related to the receiving performance of the electronic device.

Therefore, depending on the structure of the antenna and the antenna tuning circuit, antenna efficiency can be improved by changing the setting value (eg, tuning value) used in the antenna tuning circuit. As antenna efficiency improves, the radiation performance of the antenna can be improved, and thus TRP performance and/or TIS performance can also be improved.

Since the change in antenna efficiency by frequency due to the approach of the dielectric is a characteristic of electronic devices, the change in antenna efficiency by frequency due to the approach of the dielectric can be confirmed in advance. For example, electronic devices can check in advance changes in antenna efficiency for each frequency due to dielectric access in a laboratory environment. Therefore, the electronic device can pre-store the set value to be used by the antenna tuning circuit in the grip state and the set value to be used by the antenna tuning circuit in the free space state based on the change in antenna efficiency for each frequency due to the approach of the dielectric. there is. In one embodiment, the electronic device configures the settings to be used by the antenna tuning circuit in the form of a table containing, by frequency, the settings to be used by the antenna tuning circuit when in a gripped state and the settings to be used by the antenna tuning circuit when in free space. Values can be stored in advance.

FIG. 8 is a diagram for explaining the operation of an electronic device in the RRC_IDLE state or the RRC_INACTIVE state, according to an embodiment.

Before describing FIG. 8, the operation of the electronic device described in FIG. 8 (e.g., the electronic device 101 in FIGS. 1, 2A, 2B, 3A to 3C, or 4) is in the RRC_IDLE state or RRC_INACTIVE. It may be noted that this is the operation of an electronic device that exists in a state.

Referring to FIG. 8, the electronic device determines whether a call signal targeting the electronic device is received from a serving cell based on a set cycle (e.g., the first cycle) and performs a measurement operation for the serving cell. can be performed. The electronic device may perform a measurement operation for a neighboring cell based on a set cycle (e.g., second cycle).

In FIG. 8, time periods 811, 815, 817, and 821 marked “P” allow the electronic device to check whether a call signal targeting the electronic device is received from the serving cell, and Indicates a time period for performing a measurement operation on a cell, and time periods 813 and 819 marked with “M” may represent a time period in which an electronic device performs a measurement operation on an adjacent cell.

The electronic device may maintain the setting value of at least one antenna tuning circuit (e.g., the antenna tuning circuit 440 of FIG. 4 or FIG. 5) before transitioning to the RRC_IDLE state or the RRC_INACTIVE state. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates a grip touch state, the setting value is set to at least one antenna tuning circuit connected to at least one antenna (e.g., antenna 460 in FIG. 4). The frequency used in the included RF circuit (e.g., the RF circuit 450 in FIG. 5) may be a setting value used by at least one antenna tuning circuit in the grip state. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates a grip release state, the setting value is the setting used by at least one antenna tuning circuit when in free space for the frequency used in the RF circuit. It can be a value.

The electronic device maintains the setting value of at least one antenna tuning circuit before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, checks whether a call signal is received, performs a measurement operation for the serving cell, and performs a measurement operation for the adjacent cell. Measurement operations can be performed. In this way, a measurement operation performed while maintaining the setting value of at least one antenna tuning circuit before the electronic device transitions to the RRC_IDLE state or the RRC_INACTIVE state (e.g., at least one of a measurement operation for a serving cell or a measurement operation for an adjacent cell) One) will be referred to as “normal measurement operation.”

An electronic device in the RRC_IDLE state or RRC_INACTIVE state can decide whether to transition to a sleep state or wake up based on a discontinuous reception (DRX) cycle. The electronic device can check the on-duration based on the DRX cycle, check whether a call signal targeting the electronic device is received in the awake state during the on-duration, and determine whether the serving cell Measurement operations can be performed. In one embodiment, on-duration may include the duration in which the electronic device waits to receive physical downlink control channels (PDCCH) after waking up. When the on-duration expires, the electronic device may transition to a sleep state or perform a measurement operation for a neighboring cell based on a radio resource management (RRM) configuration. In Figure 8, the time period marked “P” may correspond to the on-duration.

FIG. 9 is a diagram for explaining the operation of an electronic device in the RRC_IDLE state or the RRC_INACTIVE state, according to an embodiment.

Before describing FIG. 9, the operation of the electronic device described in FIG. 9 (e.g., the electronic device 101 in FIGS. 1, 2A, 2B, 3A to 3C, or 4) is in the RRC_IDLE state or RRC_INACTIVE. It may be noted that this is the operation of an electronic device that exists in a state.

Referring to FIG. 9, the electronic device checks whether a call signal targeting the electronic device is received from the serving cell based on the set cycle (e.g., the first cycle) as described in FIG. 8, and determines whether a call signal targeting the electronic device is received from the serving cell. A measurement operation may be performed, and a measurement operation for an adjacent cell may be performed based on a set cycle (e.g., second cycle).

The reason why an electronic device performs a measurement operation on a neighboring cell may be mainly related to mobility issues such as handover. Accordingly, the electronic device may be able to skip the measurement operation for an adjacent cell when the electronic device exists in a stationary environment rather than a mobile environment. According to one embodiment, the electronic device skips the measurement operation for the adjacent cell in a time period in which the measurement operation for the adjacent cell is set to be performed, and skips the measurement operation for the adjacent cell and uses at least one antenna tuning circuit (e.g., in FIG. 4) that is currently set. The setting value (e.g., tuning value) of the antenna tuning circuit 440 may be changed from the first setting value to the second setting value, and a measurement operation for the serving cell may be performed based on the second setting value.

In one embodiment, the first setting value may be a setting value corresponding to grip state information before the electronic device transitions to the RRC_IDLE state or the RRC_INACTIVE state. For example, when the grip state information indicates a grip touch state, the first setting value is for the frequency used in the RF circuit (e.g., the RF circuit 450 in FIG. 5), and when in the grip state, at least one antenna tuning It may be a set value used by the circuit. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates the grip release state, the first setting value is for the frequency used in the RF circuit, and when in the free space state, is used by at least one antenna tuning circuit. It may be a set value.

In one embodiment, the second setting value may be a setting value that takes into account grip state information that is different (eg, opposite) from the grip state information considered in the first setting value. When the grip state information considered in the first setting value indicates a grip touch state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip release state. When the grip state information considered in the first setting value indicates a grip release state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip touch state.

In this way, the measurement operation for the adjacent cell is skipped in the time period in which the measurement operation for the adjacent cell is set to be performed, and based on the second setting value rather than the first setting value before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, The reasons for performing a measurement operation on the serving cell may be as follows.

Because the grip sensor consumes current when turned on, the electronic device can turn the grip sensor on or off depending on the state of the electronic device. To prevent current consumption due to turning on the grip sensor, the electronic device turns off the grip sensor when the state of the electronic device is RRC_IDLE or RRC_INACTIVE, and turns on the grip sensor when the state of the electronic device is RRC_CONNECTED. It can be turned on.

In this way, when the state of the electronic device is RRC_IDLE state or RRC_INACTIVE state, the grip sensor may be turned off. Accordingly, the electronic device may not be able to operate at least one antenna tuning circuit based on the proximity of the dielectric sensed by the grip sensor, resulting in performance degradation for receiving operations of the electronic device, such as receiving a call signal. In addition, performance degradation in the transmission operation of the electronic device may also occur, such as when a random access procedure is performed in the RRC_IDLE state of the electronic device.

Therefore, in the present disclosure, when the state of the electronic device transitions to the RRC_IDLE state or the RRC_INACTIVE state, even though the grip sensor is turned off, in order to prevent the transmission performance and reception performance from being deteriorated due to the grip sensor being turned off ( or to alleviate) the setting value of at least one antenna tuning circuit in a set time period such that if a set condition is satisfied (e.g., a stationary condition is satisfied), a measurement operation for a neighboring cell is performed. It may be possible to skip the measurement operation for the cell and perform the measurement operation for the serving cell based on the second setting value rather than the first setting value before transitioning to the RRC_IDLE state or RRC_INACTIVE state.

In this way, when the state of the electronic device transitions to the RRC_IDLE state or the RRC_INACTIVE state, even though the grip sensor is turned off, in order to prevent (or alleviate) the deterioration of transmission and reception performance due to the turn-off of the grip sensor, ) If the setting condition for the setting value of at least one antenna tuning circuit is satisfied (for example, when the stationary condition is satisfied), the setting value of the at least one antenna tuning circuit is changed from the first setting value to the second setting value. and a measurement operation (e.g., a measurement operation for a serving cell) performed using at least one antenna tuning circuit changed to the second setting value will be referred to as a “temporary measurement operation.”

In FIG. 9, time periods 911, 915, 917, and 921 marked “P” allow the electronic device to check whether a call signal targeting the electronic device is received from the serving cell and perform measurements for the serving cell. Indicates a time period during which an operation is performed, where the time period 913 marked with “M” may represent a time period during which the electronic device performs a measurement operation for an adjacent cell, and the time period marked “A” 919 ) was set to perform a measurement operation for an adjacent cell, but as the electronic device exists in a stationary environment, a measurement operation for the serving cell (e.g., a temporary measurement operation) is performed based on the second setting value (e.g., a changed tuning value). ) can indicate the time period for performing.

In one embodiment, temporary measurement operations may be performed based on a set ratio. For example, if the setting ratio is 50%, a temporary measurement operation may be performed in one time period corresponding to 50% of the time periods in which a measurement operation for an adjacent cell is set to be performed. In one embodiment, the setup ratio may be determined based on various parameters to suit the situation of the wireless communication network.

FIG. 10 is a flowchart illustrating an operation process of an electronic device, according to an embodiment.

Referring to FIG. 10, an electronic device (e.g., electronic device 101 of FIGS. 1, 2A, 2B, and 3A to 3C) (e.g., processor 120 of FIG. 1, first communication processor of FIG. 2A) (212) or the second communication processor 214, the integrated communication processor 260 of FIG. 2B, and the communication processor 260 of FIG. 4) may transition to the RRC_IDLE state in operation 1011.

The electronic device that has transitioned to the RRC_IDLE state or the RRC_INACTIVE state may turn off the grip sensor (eg, the grip sensor 410 in FIG. 4) in operation 1013.

In operation 1015, the electronic device may maintain the first setting value, which is the setting value of at least one antenna tuning circuit (e.g., the antenna tuning circuit 440 of FIG. 4 or 5) before transitioning to the RRC_IDLE state or the RRC_INACTIVE state. . Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates a grip touch state, the first setting value is at least one antenna tuning connected to at least one antenna (e.g., antenna 460 in FIG. 4). With respect to the frequency used in the RF circuit including the circuit (e.g., the RF circuit 450 in FIG. 5), it may be a setting value used by at least one antenna tuning circuit when in a grip state. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates the grip release state, the first setting value is for the frequency used in the RF circuit, and when in the free space state, is used by at least one antenna tuning circuit. It may be a set value. Since operation 1015 is similar to or may be implemented substantially the same as operation 613 of FIG. 6, its detailed description will be omitted here.

In operation 1017, the electronic device can check whether the stationary condition is satisfied. In one embodiment, the stationary condition may include a condition under which the electronic device can be determined to be in a stationary state.

In one embodiment, the electronic device may check whether the electronic device is in a stopped state through a sensor hub (eg, sensor module 176 in FIG. 1).

In one embodiment, the electronic device may determine whether the electronic device is in a stationary state based on at least one of an acceleration signal or an angular velocity signal obtained through a sensor hub. In one embodiment, when the amount of change in at least one of the acceleration signal or the angular velocity signal is less than the threshold change amount, the electronic device may determine that the electronic device is in a stationary state. In one embodiment, the case of checking whether an electronic device is in a stationary state based on at least one of an acceleration signal or an angular velocity signal is described as an example, but the signal sensed by a plurality of sensors included in the sensor hub is explained as an example. Based on this, it is possible to check whether the electronic device is in a stopped state.

In one embodiment, the electronic device may check whether the electronic device is in a stationary state based on the cell identifier (ID) of the serving cell and the signal strength of the serving cell. In one embodiment, the electronic device does not change the cell identifier (ID) of the serving cell, and the signal strength of the serving cell measured in the RRC_CONNECTED state immediately before transitioning to the RRC_IDLE state or RRC_INACTIVE state and the signal strength measured in the RRC_IDLE state or RRC_INACTIVE state If the difference between the signal strengths of the serving cells is less than a threshold (e.g. 10 dB), the electronic device can be confirmed to be in a stationary state. In one embodiment, the signal strength is determined by reference signal received power (RSRP), received strength signal indicator (RSSI), reference signal received quality (RSRP), and reference signal code. It may include at least one of received signal code power (RSCP), signal to noise ratio (SNR), or signal to interference plus noise ratio (SINR).

If the stationary condition is not satisfied as a result of the check in operation 1017, the electronic device may perform a first measurement operation (eg, a normal measurement operation) in operation 1019. Since the normal measurement operation can be implemented similarly or substantially the same as that described in FIG. 8, its detailed description will be omitted here.

As a result of the check in operation 1017, if the stationary condition is satisfied, the electronic device may change the setting value of at least one antenna tuning circuit from the first setting value to the second setting value in operation 1021. In one embodiment, the second setting value may be a setting value that takes into account grip state information that is different (eg, opposite) from the grip state information considered in the first setting value. When the grip state information considered in the first setting value indicates a grip touch state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip release state. When the grip state information considered in the first setting value indicates a grip release state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip touch state.

In operation 1023, the electronic device may perform a second measurement operation (eg, a temporary measurement operation) based on the second set value. Since the temporary measurement operation may be implemented similarly or substantially the same as that described in FIG. 9, its detailed description will be omitted here.

In operation 1025, the electronic device can check whether reception performance has been improved. In one embodiment, the electronic device determines whether reception performance has been improved based on whether the signal strength of the serving cell measured through the temporary measurement operation is greater than the threshold signal strength than the signal strength of the serving cell measured through the normal measurement operation. You can check it. For example, if the signal strength of the serving cell measured through the temporary measurement operation is greater than the threshold signal strength than the signal strength of the serving cell measured through the normal measurement operation, the electronic device may confirm that reception performance has been improved. In FIG. 10, the case where the electronic device checks whether reception performance has been improved through a temporary measurement operation is described as an example, but the electronic device can also check whether reception imbalance has been improved through a temporary measurement operation. there is. In one embodiment, the electronic device improves reception imbalance performance based on whether the difference between the signal strength of the serving cell measured through a temporary measurement operation and the signal strength of the serving cell measured through a normal measurement operation decreases by more than a threshold strength. You can check whether it was done or not. For example, if the difference between the RSRP of the serving cell measured through a temporary measurement operation and the RSRP of the serving cell measured through a normal measurement operation decreases by more than a threshold value (e.g., 2 dB), it can be confirmed that the reception imbalance performance has been improved.

In one embodiment, the case where the electronic device includes one grip sensor (e.g., the grip sensor 410 of FIG. 4) has been described as an example, but the electronic device may include two or more grip sensors. For example, when an electronic device includes two grip sensors, one of the two grip sensors can be used as a main grip sensor and the other can be used as a sub-grip sensor. For example, the main grip sensor may be a grip sensor disposed at the bottom of the electronic device, and the sub-grip sensor may be a grip sensor disposed at the top of the electronic device. When the electronic device includes two grip sensors, similarly to the case where the electronic device includes one grip sensor, the sensor value of at least one antenna tuning circuit corresponding to each grip sensor is set to the first set value or the second set value. Measurement operations can be performed while controlling with set values.

Table 1 below shows the signal strength (e.g. RSRP) of the serving cell obtained through the antenna corresponding to the main grip sensor and the signal strength obtained through the antenna corresponding to the sub grip sensor when the electronic device includes two grip sensors. Indicates the signal strength of the serving cell.

<Table 1>

In Table 1, when the first setting value is applied, the difference between the signal strength of the serving cell acquired through the antenna corresponding to the main grip sensor and the signal strength of the serving cell obtained through the antenna corresponding to the sub grip sensor is the second When the setting value is applied, the difference between the signal strength of the serving cell acquired through the antenna corresponding to the main grip sensor and the signal strength of the serving cell acquired through the antenna corresponding to the sub-grip sensor is more than a threshold (e.g. 2 dB). It can be seen that it decreases. For example, as shown in Table 1, a 3dB gain is generated in the antenna corresponding to the main grip sensor, and the electronic device can confirm that reception imbalance performance has been improved.

If the reception performance is improved as a result of the confirmation in operation 1025, the electronic device may maintain the setting value of at least one antenna tuning circuit at the second value in operation 1029.

If the reception performance is not improved as a result of the check in operation 1025, the electronic device may change the setting value of at least one antenna tuning circuit from the second value to the first value in operation 1027.

FIG. 11 is a diagram for explaining the operation of an electronic device in the RRC_IDLE state or the RRC_INACTIVE state, according to an embodiment.

Before describing FIG. 11, the operation of the electronic device described in FIG. 11 (e.g., the electronic device 101 of FIGS. 1, 2A, 2B, 3A to 3C, or 4) is in the RRC_IDLE state or RRC_INACTIVE. It may be noted that the electronic device existing in this state is an operation in which a random access procedure is performed.

Referring to FIG. 11, the electronic device may transition to the RRC_IDLE state or the RRC_INACTIVE state. In one embodiment, when the electronic device transitions to the RRC_IDLE state or the RRC_INACTIVE state, the electronic device may turn off the grip sensor (e.g., the grip sensor 410 in FIG. 4).

The electronic device that has transitioned to the RRC_IDLE state or the RRC_INACTIVE state includes at least one antenna tuning circuit (e.g., the antenna tuning circuit 440 of FIG. 4 or FIG. 5), corresponding to the grip sensor, before transitioning to the RRC_IDLE state or RRC_INACTIVE state. The first setting value, which is the setting value, can be maintained. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates a grip touch state, the first setting value is at least one antenna tuning connected to at least one antenna (e.g., antenna 460 in FIG. 4). With respect to the frequency used in the RF circuit including the circuit (e.g., the RF circuit 450 in FIG. 5), it may be a setting value used by at least one antenna tuning circuit when in a grip state. Before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, when the grip state information indicates the grip release state, the first setting value is for the frequency used in the RF circuit, and when in the free space state, is used by at least one antenna tuning circuit. It may be a set value.

The electronic device may transmit the first signal for random access based on the first transmission power and the first setting value in the RRC_IDLE state or the RRC_INACTIVE state. In one embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number indicated by the parameter preambleTransMax) until the second signal is received. In one embodiment, the parameter preambleTransMax may indicate the maximum number of first signal transmissions performed before failure for the random access procedure is declared.

In one embodiment, the first signal may include a random access preamble signal. In one embodiment, the first signal may include a random access preamble signal and data by the first scheduled transmission of the random access procedure. In one embodiment, when an electronic device performs a 4-step random access procedure, the first signal may include a random access preamble signal. In one embodiment, when an electronic device performs a 2-step random access procedure, the first signal may include a random access preamble signal and data by first scheduled transmission. In one embodiment, the second signal may be a response signal to the first signal. In one embodiment, the second signal may include a RAR signal. In one embodiment, the second signal may include a RAR signal and contention resolution. In one embodiment, when the electronic device performs a 4-step random access procedure, the second signal may include a RAR signal. In one embodiment, when the electronic device performs a two-step random access procedure, the second signal may include a RAR signal and contention resolution.

Even though the electronic device transmitted a random access preamble signal (marked as “Preamble” in FIG. 11) based on the first transmission power and the first set value, which is the maximum transmission power (marked as “Max power” in FIG. 11) And, the RAR signal may not be received within a set time period (e.g., the time period indicated by the parameter ra-ResponseWindow). In this case, the electronic device changes the setting value of at least one antenna tuning circuit from the first setting value to the second setting value until the RAR is received, if not before the number indicated by the parameter preambleTransMax is reached, and 2 A random access preamble signal may be transmitted based on the setting value and the first transmission power (operations 1111, 1113, and 1115). In FIG. 11, the condition under which the second set value is applied may include a condition in which the first transmission power is equal to the threshold transmission power. The threshold transmit power may be the maximum transmit power that the electronic device can use to transmit the first signal.

In one embodiment, the second setting value may be a setting value that takes into account grip state information that is different (eg, opposite) from the grip state information considered in the first setting value. When the grip state information considered in the first setting value indicates a grip touch state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip release state. When the grip state information considered in the first setting value indicates a grip release state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip touch state.

In FIG. 11, the operation of an electronic device in the RRC_IDLE state or the RRC_INACTIVE state is explained using an example of the operation when the electronic device performs a random access procedure. An electronic device in the RRC_CONNECTED state may also operate in a similar manner as described in FIG. 11 when performing a random access procedure. However, since the electronic device exists in the RRC_CONNECTED state, the first set value is not the set value of the at least one antenna tuning circuit before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, but at least one antenna at the time of transmitting the first signal. It can be the setting value of the tuning circuit.

FIG. 12 is a diagram for explaining the operation of an electronic device in the RRC_IDLE state or the RRC_INACTIVE state, according to an embodiment.

Before describing FIG. 12, the operation of the electronic device described in FIG. 12 (e.g., the electronic device 101 in FIGS. 1, 2A, 2B, 3A to 3C, or 4) is in the RRC_IDLE state or RRC_INACTIVE. It may be noted that the electronic device existing in this state is an operation in which a random access procedure is performed.

The operation of the electronic device performing the random access procedure shown in FIG. 12 is the operation of the electronic device performing the random access procedure described in FIG. 11 except at the time when the second setting value of the at least one antenna tuning circuit is applied. It may be performed similarly or substantially the same as the operation performed. In FIG. 11, although the electronic device transmitted a random access preamble signal based on the first transmission power, which is the maximum transmission power, and the first setting value, the set The case where, when the RAR signal is not received within a time period, the setting value of at least one antenna tuning circuit is transmitted from the first setting value to the second setting value has been described.

However, in Figure 12, even if the RAR signal is not received within the set time period after transmitting the random access preamble signal based on the first set value and the second transmit power less than the first transmit power, which is the maximum transmit power, A case in which the setting value of at least one antenna tuning circuit is transmitted from the first setting value to the second setting value is described (operations 1211, 1213, 1215, 1217, and 1219).

In FIG. 12, the condition under which the second set value is applied may include a condition where the first transmission power is less than the threshold transmission power. The threshold transmit power may be the maximum transmit power that the electronic device can use to transmit the first signal.

In FIG. 12, the operation of an electronic device in the RRC_IDLE state or the RRC_INACTIVE state is explained using an example of the operation when the electronic device performs a random access procedure. An electronic device in the RRC_CONNECTED state may also operate in a similar manner as described in FIG. 12 when performing a random access procedure. However, since the electronic device exists in the RRC_CONNECTED state, the first set value is not the set value of the at least one antenna tuning circuit before transitioning to the RRC_IDLE state or the RRC_INACTIVE state, but at least one antenna at the time of transmitting the first signal. It can be the setting value of the tuning circuit.

In one embodiment, when the electronic device performs a two-step random access procedure, the first signal may include a random access preamble signal and data by first scheduled transmission. In one embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number indicated by the parameter preambleTransMax) until the second signal is received. Accordingly, operation 1313 may be performed only until the maximum number of first signal transmissions is reached. In one embodiment, the second signal may be a response signal to the first signal. In one embodiment, the second signal may include a RAR signal. In one embodiment, the second signal may include a RAR signal and contention resolution. In one embodiment, when the electronic device performs a 4-step random access procedure, the second signal may include a RAR signal.

You can.

If the second signal is not received as a result of the check in operation 1315, the electronic device can check whether the set condition is satisfied in operation 1317. In one embodiment, the set condition may include a first condition where the first transmit power is equal to the threshold transmit power. The threshold transmit power may be the maximum transmit power that the electronic device can use to transmit the first signal. In one embodiment, the set condition may include a second condition in which the first transmission power is less than the threshold transmission power.

As a result of the confirmation in operation 1317, if the set condition is satisfied, the electronic device may change the setting value from the first setting value to the second setting value in operation 1319. In one embodiment, the second setting value may be a setting value that takes into account grip state information that is different (eg, opposite) from the grip state information considered in the first setting value. When the grip state information considered in the first setting value indicates a grip touch state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip release state. When the grip state information considered in the first setting value indicates a grip release state, the second setting value may be a setting value set for the frequency used in the RF circuit when the grip state information indicates a grip touch state.

In operation 1319, the electronic device may transmit the first signal based on the first transmission power or the second transmission power and the second set value. In one embodiment, the electronic device may control the RF circuit to transmit the first signal based on the first transmission power or the second transmission power and the second set value. In one embodiment, when the set condition is the first condition, the electronic device may control the RF circuit to transmit the first signal based on the first transmission power and the second set value. In one embodiment, when the set condition is the second condition, the electronic device may control the RF circuit to transmit the first signal based on the second transmission power and the second set value.

As shown in Table 2, the grip states sensed through the grip sensor may vary, and the setting value for at least one antenna tuning circuit (e.g., the antenna tuning circuit 440 of Figure 4 or Figure 5) is the grip sensor It may be determined by applying all of the grip states sensed through . In this case, the table containing the setting values to be used by the antenna tuning circuit may also include setting values corresponding to the hard grip state and death grip state as well as the grip touch state and grip release state.

In one embodiment, when the setting value to be used by the antenna tuning circuit is determined considering only the grip touch state and the grip release state, if the grip state corresponding to the first setting value is the grip touching state, it corresponds to the second setting value. The grip state used may be a grip release state.

Figure 14 is a flowchart illustrating a method of operating an electronic device, according to an embodiment.

Referring to FIG. 14, an electronic device (e.g., the electronic device 101 of FIGS. 1, 2A, 2B, 3A to 3C, or FIG. 4) (e.g., the processor 120 of FIG. 1, the electronic device 101 of FIG. 2A) The first communication processor 212 or the second communication processor 214, or the integrated communication processor 260 of FIG. 2B or FIG. 4) performs random access based on the first transmission power and the first setting value in operation 1411. The first signal for can be transmitted to the base station. In one embodiment, the setting value may include a tuning value of at least one antenna tuning circuit (eg, the antenna tuning circuit 440 of FIG. 4 or FIG. 5). In one embodiment, the electronic device may control the RF circuit to transmit the first signal for random access based on the first transmission power and the first setting value. In one embodiment, the first signal may include a random access preamble signal. In one embodiment, the first signal may include a random access preamble signal and data by the first scheduled transmission of the random access procedure. In one embodiment, when the electronic device performs a 4-step random access procedure, the first signal may include a random access preamble signal. In one embodiment, when the electronic device performs a two-step random access procedure, the first signal may include a random access preamble signal and data by first scheduled transmission. In one embodiment, the electronic device may transmit the first signal a set number of times (e.g., the number of times indicated by the parameter preambleTransMax) until the second signal is received in response to the first signal. In one embodiment, the parameter preambleTransMax may indicate the maximum number of first signal transmissions performed before failure for the random access procedure is declared. Accordingly, operation 1411 may be performed until the maximum number of first signal transmissions is reached. In one embodiment, the second signal may be a response signal to the first signal. In one embodiment, the second signal may include a RAR signal. In one embodiment, the second signal may include a RAR signal and contention resolution. In one embodiment, when the electronic device performs a 4-step random access procedure, the second signal may include a RAR signal. In one embodiment, when the electronic device performs a two-step random access procedure, the second signal may include a RAR signal and contention resolution.

In operation 1413, the electronic device can check whether a second signal is received from the base station in response to the first signal. In one embodiment, the electronic device may check whether a second signal is received in response to the first signal through an RF circuit. In one embodiment, the electronic device may determine whether a second signal is received in response to the first signal through the RF circuit within a set time period (e.g., a time period indicated by the parameter ra-ResponseWindow). In one embodiment, the parameter ra-ResponseWindow may indicate the Msg2 (RAR) window length indicated by the network, and the Msg2 (RAR) window length may be a time period corresponding to a set number of slots, for example.

If the second signal is not received as a result of the check in operation 1413, the electronic device may check whether the set condition is satisfied in operation 1415. In one embodiment, the set condition may include a condition where the first transmit power is equal to the threshold transmit power. The threshold transmission power may include the maximum transmission power (Max Tx power) that the electronic device can use to transmit the first signal.

As a result of the confirmation in operation 1415, if the set condition is satisfied, the electronic device may change the setting value from the first setting value to the second setting value in operation 1417. In one embodiment, the second setting value may be a setting value other than the first setting value among setting values that can be set for the frequency used in the RF circuit (eg, a first setting value and a second setting value). In one embodiment, the second set value may be a set value for a frequency used in the RF circuit that is set to correspond to a second state that is different from the first state of the grip sensor corresponding to the first set value.

In one embodiment, the second signal is transmitted in response to the first signal even though a set condition is met (e.g., despite transmitting the first signal using a threshold transmit power (e.g., maximum transmit power)). Cases where reception is not possible may include cases where antenna radiation performance is deteriorated due to decreased antenna efficiency. If antenna efficiency decreases, the antenna's radiation performance may deteriorate, which may result in a decrease in total radiated power (TRP) performance and/or a decrease in total isotropic sensitivity (TIS) performance. may result in Therefore, according to one embodiment, antenna efficiency can be improved by changing the setting value (eg, tuning value) used in the antenna tuning circuit from the first setting value to the second setting value. In this way, as antenna efficiency is improved, the radiation performance of the antenna can be improved, and thus TRP performance and/or TIS performance can also be improved. In this way, as TRP performance improves, when the electronic device transmits the first signal based on the first transmission power and the second setting value, the electronic device transmits the first signal based on the first transmission power and the first setting value. Compared to the case of transmitting, the probability that the first signal will reach (receive) the base station may be increased.
