For example, the RF transceiver (220) may include an analog-to-digital converter (ADC) for converting an analog signal into a digital signal. The RF transceiver (220) may include a mixer and an oscillator for down-conversion. The RF transceiver (220) may convert the RF signal into a baseband signal so that it can be processed by a processor (210). The RF transceiver (220) may include one or more receiving ports.

[0054] In one embodiment, the electronic device (101) may include RFFE modules (e.g., RFFE module (233), RFFE module (234), RFFE module (235), RFFE module (244), and RFFE module (254)). Wireless communication systems are evolving toward supporting higher data transmission rates to meet the ever-increasing demand for wireless data traffic. To support various frequency combinations, a plurality of transmit (Tx) / receive (Rx) RFFE modules may be placed around an RF transceiver (220). For example, the RFFE module (233) may be a PAMid comprising one or more power amplifiers and RF components for transmitting signal processing (e.g., a duplexer or a filter). For example, the RFFE module (233) may be an LPAMid comprising a power amplifier and / or a low noise amplifier (LNA). For example, the RFFE module (233) may include a control circuit for controlling one or more power amplifiers within the RFFE module (233) under the control of the processor (210) and / or the RF transceiver (220). For example, the control circuit of the RFFE module (233) may control the bias current (or voltage) of the power amplifier under the control of the processor (210) and / or the RF transceiver (220). For example, the control circuit of the RFFE module (233) may change parameters by controlling a signal path through a switch circuit within the power amplifier under the control of the processor (210) and / or the RF transceiver (220). In one example, the parameters may include gain and / or output power. However, this is merely an example and the present disclosure is not limited thereto. The parameters may include additional parameters besides the examples described above.In addition to being a control circuit, the control circuit may be referred to as a control unit, a controller, a logic circuit, a CMOS (complementary metal-oxide-semiconductor) controller, a CMOS logic circuit, a CMOS control circuit, a control logic circuit, an RFFE controller, an RFFE control circuit, an RFFE module control circuit, or any other term having an equivalent technical or functional meaning. The description of the RFFE module (233) described above may be applied substantially the same to the RFFE module (234), RFFE module (234), RFFE module (235), RFFE module (244), and RFFE module (254).

[0055] FIG. 3 illustrates the components of an RFFE module. In FIG. 3, noise caused by control according to a MIPI (mobile industry processor interface) command (301) is described. FIG. 3 is described based on an RFFE (radio frequency front end) module (310) including a power amplifier (PA) (330) in the transmit path, but this is merely an example and the present disclosure is not limited thereto. For example, the description of FIG. 3 may also apply to an RFFE module including a LNA (low noise amplifier) ​​in the receive path. Hereinafter, control by the processor (210) and / or RF transceiver (220) may mean control based on a MIPI command (301).

[0056] Referring to FIG. 3, the RFFE module (310) may include a control circuit (320) and a power amplifier (330). For example, the RFFE module (310) may correspond to one of the RFFE module (233), RFFE module (234), RFFE module (235), RFFE module (244), or RFFE module (254) of FIG. 2a and FIG. 2b.

[0057] In one embodiment, the RFFE module (310) may include a control circuit (320). For example, the control circuit (320) may control the power amplifier (330) based on a MIPI command (301) obtained from the processor (210) and / or the RF transceiver (220). For example, the control circuit (320) may control the bias current (or voltage) of the power amplifier (330) based on a MIPI command (301) obtained from the processor (210) and / or the RF transceiver (220). The control circuit (320) may control the bias current (or voltage) of the power amplifier (330) by providing the power amplifier (330) with a control signal for controlling a bias circuit inside the power amplifier (330). For example, the control circuit (320) can control parameters of the power amplifier (330) based on MIPI commands (301) obtained from the processor (210) and / or the RF transceiver (220). The control circuit (320) can control the parameters by providing the power amplifier (330) with a control signal for controlling the parameters of the power amplifier (330). In one example, the parameters may include gain and / or output power. However, this is merely an example and the present disclosure is not limited thereto. The parameters may further include other parameters in addition to the examples described above.

[0058] In one embodiment, the RFFE module (310) may include a power amplifier (330). The power amplifier (330) may be driven based on a supply voltage (303) provided by a modulator (or power supply circuit) (e.g., modulator (243) and / or modulator (253) of FIG. 2a and FIG. 2b). For example, the power amplifier (330) may amplify an RF signal (e.g., RF input (302)) provided by an RF transceiver (220). By providing the amplified RF signal (e.g., RF output (303)) to an antenna, the amplified RF signal may be radiated into the air.

[0059] As described above, the control circuit (320) of the RFFE module (310) can control the power amplifier (330) based on the MIPI command (301). The control circuit (320) of the RFFE module (310) can control the power amplifier (330) by providing a control signal to the power amplifier (330) to control the power amplifier (330). Control according to the control signal of the control circuit (320) can be performed while the power amplifier (330) amplifies the RF signal. The control signal of the control circuit (320) may cause noise in the RF signal. Noise generated while the RF signal is amplified in the power amplifier (330) may cause a degradation in the transmission performance of the electronic device (101). In the RFFE module of the receiving path, noise may be generated by control according to the MIPI command while the RF signal is amplified by the LNA. Noise generated while the RF signal is amplified in the LNA can cause a decrease in the receiving performance of the electronic device (101). An example of reduced transmission and reception performance due to noise caused by the control signal of the control circuit (320) is described in FIG. 4a and FIG. 4b.

[0060] Figure 4a shows a graph representing the output of a power amplifier according to noise caused by MIPI commands.

[0061] In the graph exemplified in FIG. 4a, the horizontal axis represents frequency, and the vertical axis represents the magnitude of the output power of a power amplifier (PA) (e.g., the power amplifier (330) of FIG. 3). The waveform (401) shown in the graph represents the magnitude of the output power of the power amplifier at different frequencies.

[0062] The control circuit of the RFFE (radio frequency front end) module can control the power amplifier based on MIPI commands. The control circuit of the RFFE module can control the power amplifier by providing a control signal to the power amplifier to control the power amplifier. The control signal may cause noise in the RF signal while the power amplifier amplifies the RF signal. For example, spurious (402) may occur in the output power of the power amplifier due to the control signal. Spurious (402) may cause a degradation of the EVM (error vector magnitude). Depending on the time at which the spurious (402) occurs, additional degradation of transmission performance may occur. The additional degradation of transmission performance caused depending on the time at which the spurious (402) occurs is described in FIG. 4b.

[0063] FIG. 4b illustrates time-domain resources to explain noise caused by MIPI commands. In FIG. 4b, the first slot (420) and the second slot (430) contain 14 OFDM (orthogonal frequency division multiplexing) symbols. However, this is merely an example for illustrative purposes and the present disclosure is not limited thereto. The number of symbols in the first slot (420) and the second slot (430) may be determined according to the subcarrier interval (e.g., 30 kHz, 60 kHz, 120 kHz, 240 kHz, 480 kHz, 960 kHz, or 1920 kHz).

[0064] In one embodiment, control by MIPI (mobile industry processor interface) commands may be performed periodically. For example, the processor (210) and / or RF (radio frequency) transceiver (220) may periodically provide MIPI commands to the RFFE (radio frequency front end) module to maintain the settings of the power amplifier (PA) of the RFFE module. In the example illustrated in FIG. 4b, control by MIPI command (421) may be performed at the twelfth symbol of the first slot (420), and control by MIPI command (431) may be performed at the twelfth symbol of the second slot (430). The MIPI command (421) at the twelfth symbol of the first slot (420) and the MIPI command (431) at the twelfth symbol of the second slot (430) may be the same command provided to maintain the settings of the power amplifier of the RFFE module. Control by the MIPI command (431) at the twelfth symbol of the second slot (430) may not be essential because the MIPI command (421) and the MIPI command (431) are identical. According to one embodiment, the RFFE module can reduce the occurrence of noise by not performing control according to the MIPI command (431) when the same MIPI command (431) as the MIPI command (421) obtained in the first slot (420) is obtained.

[0065] In one embodiment, the MIPI command (431) in the twelfth symbol of the second slot (430) may be different from the MIPI command (421) in the twelfth symbol of the first slot (420). Since the MIPI command (431) in the second slot (430) is different from the MIPI command (421) in the first slot (420), the RFFE module needs to perform control according to the MIPI command (431). However, the twelfth symbol of the second slot (430) where control according to the MIPI command (431) is performed may be a symbol to which a reference signal (e.g., DMRS (demodulation reference signal)) for decoding a data signal is assigned. When control according to the MIPI command is performed in a symbol to which a reference signal is assigned, a degradation of the transmission and reception performance of the electronic device (101) may occur. For example, the electronic device (101) may be a transmitting device. When control according to a MIPI command is performed on a symbol to which a reference signal is assigned, the reference signal may be distorted by spurious (e.g., spurious (402) in FIG. 4a) according to the MIPI command. Since the reference signal is distorted, the receiving device may fail to decode the data signal. Since decoding the data signal fails, the transmission performance of the electronic device (101) may be degraded. In another example, the electronic device (101) may be a receiving device. When control according to a MIPI command is performed on a symbol to which a reference signal is assigned, the reference signal may be distorted by spurious (e.g., spurious (402) according to the MIPI command). Since the reference signal is distorted, the electronic device (101) may fail to decode the data signal. Since decoding the data signal fails, the reception performance of the electronic device (101) may be degraded. According to one embodiment, the RFFE module can avoid control according to a MIPI command being performed at a symbol to which a reference signal is assigned by delaying control according to a MIPI command.

[0066] In the following, an electronic device and an RFFE module are described for reducing noise caused by repetitive MIPI commands and avoiding distortion of the reference signal by MIPI commands.

[0067] FIG. 5 illustrates components of an RFFE module for reducing noise caused by MIPI commands. FIG. 5 is described based on an RFFE (radio frequency front end) module (510) including a power amplifier (PA) (530) in the transmit path. However, this is merely an example and the present disclosure is not limited thereto. The description of FIG. 5 may be applied in the same or similar way to an RFFE module including a low noise amplifier (LNA) in the receive path. In the following, control by the processor (210) and / or the RF (radio frequency) transceiver (220) may mean control based on MIPI (mobile industry processor interface) commands (501).

[0068] Referring to FIG. 5, an RFFE module (510) according to one embodiment may include a control circuit (520) and a power amplifier (530).

[0069] In one embodiment, the RFFE module (510) may include a control circuit (520). The control circuit (520) may control the power amplifier (530) based on a MIPI command (501) obtained from the processor (210) and / or the RF transceiver (220). For example, the control circuit (520) may control the bias current (or voltage) of the power amplifier (530) based on a MIPI command (501) obtained from the processor (210) and / or the RF transceiver (220). The control circuit (520) may control the bias current (or voltage) of the power amplifier (530) by providing the power amplifier (530) with a control signal for controlling a bias circuit inside the power amplifier (530). For example, the control circuit (520) can control parameters of the power amplifier (530) based on MIPI commands (501) obtained from the processor (210) and / or the RF transceiver (220). The control circuit (520) can control the parameters by providing the power amplifier (530) with a control signal for controlling the parameters of the power amplifier (530). In one example, the parameters may include gain and / or output power. However, this is merely an example and the present disclosure is not limited thereto. The parameters may further include other parameters in addition to the examples described above.

[0070] In one embodiment, the RFFE module (510) may include a power amplifier (530). The power amplifier (530) may be driven based on a supply voltage (503) provided by a modulator (or power supply circuit) (e.g., modulator (243) and / or modulator (253) of FIG. 2a and FIG. 2b). For example, the power amplifier (530) may amplify an RF signal (e.g., RF input (502)) obtained from an RF transceiver (220). By providing the amplified RF signal (e.g., RF output (503)) to an antenna, the amplified RF signal may be radiated into the air.

[0071] In one embodiment, the control circuit (520) of the RFFE module (510) may include a comparison circuit (521), a memory (522), and a delay circuit (523).

[0072] In one embodiment, the control circuit (520) may include a comparison circuit (521). The comparison circuit (521) may be configured to identify whether a MIPI command obtained from the processor (210) and / or the RF transceiver (220) is identical to a MIPI command obtained previously (preceding or just before). For example, the comparison circuit (521) may be configured to identify whether a MIPI command obtained from a second slot (e.g., the second slot (430) in FIG. 4b) (e.g., MIPI command (431) in FIG. 4b)) is identical to a MIPI command obtained from a first slot (e.g., the first slot (420) in FIG. 4b) (e.g., MIPI command (421) in FIG. 4b). The comparison circuit (521) may be configured to refrain from providing a MIPI command to the delay circuit (523) upon identifying that the MIPI command obtained from the processor (210) and / or the RF transceiver (220) is identical to a previously obtained MIPI command. The comparison circuit (521) may be configured to provide a MIPI command to the delay circuit (523) upon identifying that the MIPI command obtained from the processor (210) and / or the RF transceiver (220) is different from a previously obtained MIPI command. In one example, the comparison circuit (521) may be referred to as a comparator, a MIPI comparator, or other terms having an equivalent technical / functional meaning.

[0073] In one embodiment, the control circuit (520) may include a memory (522). The memory (522) may be configured to store information about a previously acquired MIPI command so that a comparison circuit (521) can identify whether a MIPI command acquired from the processor (210) and / or RF transceiver (220) is identical to a previously acquired MIPI command (preceding or just before). The memory (522) may store, per radio access technology (RAT), the value of a time interval defined (or determined) so that a delay circuit (523) delays the time at which the MIPI command is executed. For example, the time interval may be defined (or determined) so that control by the MIPI command is not performed at a symbol to which a reference signal (e.g., demodulation reference signal (DMRS)) is assigned. For example, a time interval may be defined (or determined) such that control by MIPI commands is performed within the time interval to which the CP (cyclic prefix) of the data signal is assigned. In one example, memory (522) may store the value of a first time interval defined for an LTE (long term evolution) network. In one example, memory (522) may store the value of a second time interval defined for an NR (new radio) network. In an example that is not limited, memory (522) may store the values ​​of time intervals defined by subcarrier spacing. In one example, memory (522) may be referred to as a buffer, a memory block, or other terms having an equivalent technical / functional meaning.

[0074] In one embodiment, the control circuit (520) may include a delay circuit (523). The delay circuit (523) may be configured to delay the time at which a MIPI command obtained from the processor (210) and / or the RF transceiver (220) is executed. For example, the delay circuit (523) may be configured to delay the time at which a MIPI command is executed so that control by the MIPI command is not performed at a symbol to which a reference signal (e.g., DMRS) is assigned. For example, the delay circuit (523) may be configured to delay the time at which a MIPI command is executed so that control by the MIPI command is performed at a time interval to which a cyclic prefix (CP) of the data signal is assigned.

[0075] In the following, operations of an RFFE module (510) for reducing noise caused by control according to a MIPI command (501) are described. At least some of the operations of the RFFE module (510) may be controlled by a control circuit (520). The operations of the RFFE module (510) may be performed using components of the control circuit (520) (e.g., a comparison circuit (521), a memory (522), and a delay circuit (523)). In the following, the operations of the RFFE module (510) are described sequentially. However, the operations of the RFFE module (510) are not necessarily performed sequentially. For example, at least two operations may be performed in parallel.

[0076] In one embodiment, the RFFE module (510) may perform an initialization operation in response to the booting of the electronic device (101). For example, the RFFE module (510) may control the memory (522) so that the memory (522) of the control circuit (520) is initialized. For example, the RFFE module (510) may control the comparison circuit (521) so that the register of the control circuit (520) is initialized. For example, the register may be a component of the comparison circuit (521) for recording (or storing) a current MIPI instruction, a previous MIPI instruction (or a MIPI instruction stored in the memory (522)), and / or a MIPI instruction provided to the power amplifier (530). For example, when an initialization operation is performed, the register for controlling the RFFE module (510) may have an initial value (e.g., 0x00) or be in a blank state. In one example, the register may be as shown in [Table 1] below.

[0077] Register Data (Input) Data (Memory) Data (MIPI provided to PA) 0x01---

[0078] In one embodiment, the RFFE module (510) may obtain a first MIPI command from the processor (210) and / or the RF transceiver (220) after performing an initialization operation. For example, the first MIPI command may be obtained from a first slot (e.g., the first slot (420) in FIG. 4b). The RFFE module (510) may control the power amplifier (530) based on the first MIPI command. For example, the RFFE module (510) may generate a control signal to control the power amplifier (530) based on the first MIPI command. The RFFE module (510) may perform control according to the first MIPI command by providing the control signal to the power amplifier (530). The RFFE module (510) may update the registers of the control circuit (520) based on the first MIPI command. In one example, the updated registers may be as shown in [Table 2] below.

[0079] Register Data (Input) Data (Memory) Data (MIPI provided to PA) 0x010x01Ox01Ox01

[0080] In one embodiment, the RFFE module (510) may obtain a second MIPI command from the processor (210) and / or the RF transceiver (220). For example, the second MIPI command may be obtained from a second slot (e.g., the second slot (430) in FIG. 4b). The comparison circuit (521) of the RFFE module (510) may identify whether the second MIPI command is identical to the first MIPI command stored in memory (522).

[0081] In one embodiment, the RFFE module (510) may refrain from controlling the power amplifier (530) based on the second MIPI command upon identifying that the second MIPI command is identical to the first MIPI command stored in memory (522). For example, the RFFE module (510) may refrain from generating a control signal according to the second MIPI command upon identifying that the second MIPI command is identical to the first MIPI command. By refraining from controlling the power amplifier (530) based on the second MIPI command, the RFFE module (510) may reduce noise caused by repetitive MIPI commands. The RFFE module (510) may update the registers of the control circuit (520) upon identifying that the second MIPI command is identical to the first MIPI command. In one example, the updated registers may be as shown in [Table 3] below.

[0082] Register Data (Input) Data (Memory) Data (MIPI provided to PA) 0x01 0x01 Ox01 Ignore

[0083] In one embodiment, the RFFE module (510) can control the power amplifier (530) based on the second MIPI command upon identifying that the second MIPI command is different from the first MIPI command stored in memory (522). For example, the RFFE module (510) can generate a control signal for controlling the power amplifier (530) based on the second MIPI command upon identifying that the second MIPI command is different from the first MIPI command. The RFFE module (510) can identify a time interval (or duration) for delaying control according to the second MIPI command based on the RAT (or subcarrier interval) at which the RFFE module operates. For example, the RFFE module (510) can provide the control signal to the power amplifier (530) at a second time, which is a specified time interval after the first time at which the second MIPI command was acquired. In one example, the first time at which the second MIPI command is acquired may be included in a symbol to which a reference signal (e.g., DMRS (demodulation reference signal)) for decoding a data signal is assigned. In one example, the second time at which control according to the second MIPI command is performed may be included in a cyclic prefix (CP) of the data signal. The RFFE module (510) can reduce the degradation of the transmission and reception performance of the electronic device (101) by avoiding the performance of control according to the MIPI command in the symbol to which the reference signal is assigned. For example, the RFFE module (510) may store the second MIPI command in memory (522) upon identification that the second MIPI command is different from the first MIPI command. For example, the RFFE module (510) may update the register of the control circuit (520) upon identification that the second MIPI command is different from the first MIPI command. In one example, the updated register can be updated as shown in [Table 4] below.

[0085] In FIG. 5, for convenience of explanation, the operations of the RFFE module (510) for reducing noise according to MIPI commands in the first slot and the second slot after booting the electronic device (101) are described. However, this is for illustrative purposes only and the present disclosure is not limited thereto. The operations described in FIG. 5 may be performed in any consecutive or discontinuous slots among the plurality of slots.

[0086] FIG. 6 illustrates components of an RFFE module for reducing noise caused by MIPI commands. FIG. 6 is described based on an RFFE (radio frequency front end) module (510) including a power amplifier (PA) (530) in the transmit path. However, this is merely an example and the present disclosure is not limited thereto. The description of FIG. 6 may be applied in the same or similar way to an RFFE module including a low noise amplifier (LNA) in the receive path. In the following, control by the processor (210) and / or the RF (radio frequency) transceiver (220) may mean control based on MIPI (mobile industry processor interface) commands (501).

[0087] Referring to FIG. 6, an RFFE module (510) according to one embodiment may include a control circuit (520) and a power amplifier (530).

[0088] In one embodiment, the RFFE module (510) may include a control circuit (520). The control circuit (520) may control the power amplifier (530) based on a MIPI command (501) obtained from the processor (210) and / or the RF transceiver (220). For example, the control circuit (520) may control the bias current (or voltage) of the power amplifier (530) based on a MIPI command (501) obtained from the processor (210) and / or the RF transceiver (220).

The control circuit (520) can control the parameters by providing the power amplifier (530) with a control signal for controlling the parameters of the power amplifier (530). In one example, the parameters may include gain and / or output power. However, this is merely an example and the present disclosure is not limited thereto. The parameters may further include other parameters in addition to the examples described above.

[0089] In one embodiment, the RFFE module (510) may include a power amplifier (530). The power amplifier (530) may be driven based on a supply voltage (503) provided by a modulator (or power supply circuit) (e.g., modulator (243) and / or modulator (253) of FIG. 2a and FIG. 2b). For example, the power amplifier (530) may amplify an RF signal (e.g., RF input (502)) obtained from an RF transceiver (220).

In one example, the memory (522) may be referred to as a buffer, a memory block, or other terms having an equivalent technical or functional meaning.

[0093] In the following, the operations of an RFFE module (510) for reducing noise caused by control according to a MIPI command (501) are described. At least some of the operations of the RFFE module (510) may be controlled by a control circuit (520).

In the following, the operations of the RFFE module (510) are described sequentially. However, the operations of the RFFE module (510) are not necessarily performed sequentially. For example, at least two operations may be performed in parallel.

[0094] In one embodiment, the RFFE module (510) may perform an initialization operation in response to the booting of the electronic device (101). For example, the RFFE module (510) may control the memory (522) so that the memory (522) of the control circuit (520) is initialized. For example, the RFFE module (510) may control the comparison circuit (521) so that the register of the control circuit (520) is initialized. For example, the register may be a component of the comparison circuit (521) for recording (or storing) a current MIPI instruction, a previous MIPI instruction (or a MIPI instruction stored in the memory (522)), and / or a MIPI instruction provided to the power amplifier (530). For example, when an initialization operation is performed, the register for controlling the RFFE module (510) may have an initial value (e.g., 0x00) or be in a blank state. In one example, the register may be as shown in [Table 1].

[0095] In one embodiment, the RFFE module (510) may obtain a first MIPI command from the processor (210) and / or the RF transceiver (220) after performing an initialization operation. For example, the first MIPI command may be obtained from a first slot (e.g., the first slot (420) in FIG. 4b). The RFFE module (510) may control the power amplifier (530) based on the first MIPI command. For example, the RFFE module (510) may generate a control signal to control the power amplifier (530) based on the first MIPI command. The RFFE module (510) may perform control according to the first MIPI command by providing the control signal to the power amplifier (530). The RFFE module (510) may update the registers of the control circuit (520) based on the first MIPI command. The updated registers may be as shown in [Table 2].

[0096] In one embodiment, the RFFE module (510) may obtain a second MIPI command from the processor (210) and / or the RF transceiver (220). For example, the second MIPI command may be obtained from a second slot (e.g., the second slot (430) in FIG. 4b). The comparison circuit (521) of the RFFE module (510) may identify whether the second MIPI command is identical to the first MIPI command stored in memory (522).

[0097] In one embodiment, the RFFE module (510) may refrain from controlling the power amplifier (530) based on the second MIPI command upon identifying that the second MIPI command is identical to the first MIPI command stored in memory (522). For example, the RFFE module (510) may refrain from generating a control signal according to the second MIPI command upon identifying that the second MIPI command is identical to the first MIPI command. By refraining from controlling the power amplifier (530) based on the second MIPI command, the RFFE module (510) may reduce noise caused by repetitive MIPI commands. The RFFE module (510) may update the registers of the control circuit (520) upon identifying that the second MIPI command is identical to the first MIPI command. The updated registers may be as shown in [Table 3].

[0098] In one embodiment, the RFFE module (510) can control the power amplifier (530) based on the second MIPI command based on the identification that the second MIPI command is different from the first MIPI command stored in memory (522). For example, the RFFE module (510) can generate a control signal to control the power amplifier (530) based on the second MIPI command based on the identification that the second MIPI command is different from the first MIPI command. The RFFE module (510) can provide the generated control signal to the power amplifier (530). For example, the RFFE module (510) can store the second MIPI command in memory (522) based on the identification that the second MIPI command is different from the first MIPI command. For example, the RFFE module (510) can update the registers of the control circuit (520) upon identifying that the second MIPI command is different from the first MIPI command. In one example, the updated registers may be as shown in [Table 4].

[0099] In FIG. 6, for convenience of explanation, the operations of the RFFE module (510) for reducing noise according to MIPI commands in the first slot and the second slot after booting the electronic device (101) are described. However, this is for illustrative purposes only and the present disclosure is not limited thereto. The operations described in FIG. 6 may be performed in any consecutive slot among a plurality of slots.

[0100] FIG. 7 illustrates components of an RFFE module for reducing noise caused by MIPI commands. FIG. 7 is described based on an RFFE (radio frequency front end) module (510) including a power amplifier (PA) (530) in the transmit path. However, this is merely an example and the present disclosure is not limited thereto. The description of FIG. 7 may be applied in the same or similar way to an RFFE module including a low noise amplifier (LNA) in the receive path. In the following, control by the processor (210) and / or the RF (radio frequency) transceiver (220) may mean control based on MIPI (mobile industry processor interface) commands (501).

[0101] Referring to FIG. 7, an RFFE module (510) according to one embodiment may include a control circuit (520) and a power amplifier (530).

[0102] In one embodiment, the RFFE module (510) may include a control circuit (520). The control circuit (520) may control the power amplifier (530) based on a MIPI command (501) obtained from the processor (210) and / or the RF transceiver (220). For example, the control circuit (520) may control the bias current (or voltage) of the power amplifier (530) based on a MIPI command (501) obtained from the processor (210) and / or the RF transceiver (220). The control circuit (520) may control the bias current (or voltage) of the power amplifier (530) by providing the power amplifier (530) with a control signal for controlling a bias circuit inside the power amplifier (530). For example, the control circuit (520) can control parameters of the power amplifier (530) based on MIPI commands (501) obtained from the processor (210) and / or the RF transceiver (220). The control circuit (520) can control the parameters by providing the power amplifier (530) with a control signal for controlling the parameters of the power amplifier (530). In one example, the parameters may include gain and / or output power. However, this is merely an example and the present disclosure is not limited thereto. The parameters may further include other parameters in addition to the examples described above.

[0103] In one embodiment, the RFFE module (510) may include a power amplifier (530). The power amplifier (530) may be driven based on a supply voltage (503) provided by a modulator (or power supply circuit) (e.g., modulator (243) and / or modulator (253) of FIG. 2a and FIG. 2b). For example, the power amplifier (530) may amplify an RF signal (e.g., RF input (502)) obtained from an RF transceiver (220). By providing the amplified RF signal (e.g., RF output (503)) to an antenna, the amplified RF signal may be radiated into the air.

[0104] In one embodiment, the control circuit (520) of the RFFE module (510) may include a memory (522) and a delay circuit (523).

[0105] In one embodiment, the control circuit (520) may include a memory (522). The memory (522) may store, per radio access technology (RAT), the value of a time interval defined (or determined) so that the delay circuit (523) delays the time at which a MIPI command is executed. For example, the time interval may be defined (or determined) so that control by the MIPI command is not performed at a symbol assigned to a reference signal (e.g., demodulation reference signal (DMRS)). For example, the time interval may be defined (or determined) so that control by the MIPI command is performed within a time interval assigned to a cyclic prefix (CP) of a data signal. In one example, the memory (522) may store the value of a first time interval defined for a long term evolution (LTE) network. In one example, the memory (522) may store the value of a second time interval defined for a new radio (NR) network. In a non-limiting example, memory (522) may store values ​​of time intervals defined by subcarrier spacing. In one example, memory (522) may be referred to as a buffer, a memory block, or other terms having an equivalent technical / functional meaning.

[0106] In one embodiment, the control circuit (520) may include a delay circuit (523). The delay circuit (523) may be configured to delay the time at which a MIPI command obtained from the processor (210) and / or the RF transceiver (220) is executed. For example, the delay circuit (523) may be configured to delay the time at which a MIPI command is executed so that control by the MIPI command is not performed at a symbol to which a reference signal (e.g., DMRS) is assigned. For example, the delay circuit (523) may be configured to delay the time at which a MIPI command is executed so that control by the MIPI command is performed at a time interval to which a cyclic prefix (CP) of the data signal is assigned.

[0107] In the following, the operations of an RFFE module (510) for reducing noise caused by control according to a MIPI command (501) are described. At least some of the operations of the RFFE module (510) may be controlled by a control circuit (520). The operations of the RFFE module (510) may be performed using components of the control circuit (520) (e.g., memory (522) and delay circuit (523)). In the following, the operations of the RFFE module (510) are described sequentially. However, the operations of the RFFE module (510) are not necessarily performed sequentially. For example, at least two operations may be performed in parallel.

[0108] In one embodiment, the RFFE module (510) may perform an initialization operation in response to the booting of the electronic device (101). For example, the RFFE module (510) may control the memory (522) so that the memory (522) of the control circuit (520) is initialized. For example, the RFFE module (510) may initialize the register of the control circuit (520). For example, the register may be a component for recording (or storing) a current MIPI instruction, a time interval defined to delay control according to the MIPI instruction, and / or a MIPI instruction provided to the power amplifier (530). For example, after performing the initialization operation, the RFFE module (510) may record the time interval defined to delay control according to the MIPI instruction in the register. For example, the time interval may be determined based on the RAT (or subcarrier interval). After performing an initialization operation, the RFFE module (510) can obtain a predetermined time interval from the memory (130) of the electronic device (101). The RFFE module (510) can record the predetermined time interval in a register. In one example, the register may be as shown in [Table 5] below.

[0109] Register Data (Input) Delay Data (MIPI provided to PA) 0x01-22μs-

[0110] In one embodiment, the RFFE module (510) can obtain a first MIPI command from the processor (210) and / or RF transceiver (220) after performing an initialization operation. For example, the first MIPI command may be acquired in a first slot (e.g., the first slot (420) in FIG. 4b). The RFFE module (510) may control the power amplifier (530) based on the first MIPI command. For example, the RFFE module (510) may generate a control signal for controlling the power amplifier (530) based on the first MIPI command. The RFFE module (510) may identify a time interval (e.g., 22 μs) for delaying control according to the first MIPI command based on the RAT (or subcarrier interval) at which the RFFE module (510) operates. The RFFE module (510) may provide the control signal to the power amplifier (530) at a second time, which is after the time interval identified from the first time at which the first MIPI command was acquired. In one example, the first time at which the first MIPI command was acquired is the data signal A reference signal for decoding (e.g., DMRS (demodulation reference signal)) may be included in the assigned symbol. In one example, a second time during which control according to the first MIPI command is performed may be included in the CP (cyclic prefix) of the data signal. The RFFE module (510) can reduce the degradation of the transmission and reception performance of the electronic device (101) by avoiding control according to the MIPI command in the symbol where the reference signal is assigned. For example, the RFFE module (510) may update the registers of the control circuit (520) based on the first MIPI command. The updated registers may be as shown in [Table 6] below.

[0112] In one embodiment, the RFFE module (510) may obtain a second MIPI command from the processor (210) and / or the RF transceiver (220). For example, the second MIPI command may be obtained from a second slot (e.g., the second slot (430) in FIG. 4b). The RFFE module (510) may generate a control signal for controlling the power amplifier (530) based on the second MIPI command. The RFFE module (510) may identify a time interval for delaying control according to the second MIPI command based on the RAT (or subcarrier interval) in which the RFFE module operates. For example, the RFFE module (510) may provide the control signal to the power amplifier (530) at a fourth time, which is after the time interval identified from the third time in which the second MIPI command was obtained. In one example, the third time at which the second MIPI command is acquired may be included in a symbol to which a reference signal (e.g., DMRS) for decoding a data signal is assigned. In one example, the fourth time at which control according to the second MIPI command is performed may be included in a cyclic prefix (CP) of the data signal. The RFFE module (510) can reduce the degradation of the transmission and reception performance of the electronic device (101) by avoiding control according to the MIPI command being performed in a symbol to which a reference signal is assigned.

For example, at least some of the operations may be controlled by the processor (210) of the electronic device (101), the RF (radio frequency) transceiver (220), and / or the control circuit (520) of the RFFE module (510). In the following, each operation may be performed sequentially, but is not necessarily performed sequentially. For example, the order of each operation may be changed. For example, at least two operations may be performed in parallel. FIG. 11 is described based on an RFFE module (510) including a power amplifier (PA) (530) of a transmit path. However, this is merely an example and the present disclosure is not limited thereto. The operations of FIG. 11 may also be applied to an RFFE module including a low noise amplifier (LNA) in the receive path. In this disclosure, terms such as “first” and “second” are used within the description of the drawings to distinguish a component from another component and do not limit the components in any other aspect. For example, regarding the first MIPI command of FIG. 11, reference may be made to the description of the second MIPI command of FIG. 5 through 10. For example, regarding the second MIPI command of FIG. 11, reference may be made to the description of the first MIPI command of FIG. 5 through 10.

[0135] Referring to FIG. 11, in operation 1101, an electronic device (101) according to one embodiment can identify whether a first MIPI (mobile industry processor interface) command corresponds to (or is identical to) a second MIPI command stored in an RFFE module (510).

[0136] In one embodiment, the electronic device (101) can identify whether a first MIPI command obtained (or generated) from the processor (210) and / or the RF transceiver (220) corresponds to (or is identical to) a second MIPI command stored in the memory (522) of the RFFE module (510). The second MIPI command may be obtained prior to (or just before) the first MIPI command. For example, the second MIPI command may be obtained in a first slot (e.g., the first slot (420) in FIG. 4b), and the first MIPI command may be obtained in a second slot following the first slot (e.g., the second slot (430) in FIG. 4b). The electronic device (101) can identify whether the first MIPI command corresponds to (or is identical to) the second MIPI command. In operation 1101, the electronic device (101) according to one embodiment may perform operation 1102 if the first MIPI (mobile industry processor interface) command corresponds to (or is identical to) the second MIPI command stored in the RFFE module (510). In operation 1101, the electronic device (101) according to one embodiment may perform operation 1103 if the first MIPI (mobile industry processor interface) command does not correspond to (or is different from) the second MIPI command stored in the RFFE module (510).

[0137] In operation 1102, an electronic device (101) according to one embodiment may refrain from controlling an RFFE module (510) (or a power amplifier (530) of the RFFE module (510)) based on a first MIPI command. For example, the electronic device (101) may refrain from controlling the RFFE module (510) based on the first MIPI command upon identifying that the first MIPI command corresponds to (or is identical to) a second MIPI command stored in the RFFE module (510). By not performing control according to the first MIPI command which is identical to a previously acquired second MIPI command, the electronic device (101) may reduce noise caused by repetitive MIPI commands.

[0138] In operation 1103, an electronic device (101) according to one embodiment may refrain from controlling the RFFE module (510) (or the power amplifier (530) of the RFFE module (510)) based on the first MIPI command at a first time when the first MIPI command is acquired. For example, the electronic device (101) may refrain from controlling the RFFE module (510) based on the first MIPI command at a first time when the first MIPI command is acquired, upon identification that the first MIPI command does not correspond to (or is different from) the second MIPI command stored in the RFFE module (510). For example, since the first MIPI command is different from the second MIPI command, the electronic device (101) needs to control the RFFE module (510) based on the first MIPI command. However, the first time during which control according to the first MIPI command is performed may include a reference signal (e.g., DMRS (demodulation reference signal)) for decoding the data signal in the assigned symbol. Accordingly, the electronic device (101) can avoid the degradation of the transmission and reception performance of the electronic device (101) by not performing control according to the first MIPI command during the first time.

[0139] In operation 1104, an electronic device (101) according to one embodiment may control an RFFE module (510) (or a power amplifier (530) of the RFFE module (510)) based on a first MIPI command at a second time interval after a specified time interval from a first time. For example, the electronic device (101) may identify a time interval for delaying control according to the first MIPI command based on the radio access technology (RAT) (or subcarrier spacing) in which the RFFE module (510) operates. The electronic device (101) may control the RFFE module (510) based on the first MIPI command at a second time interval after a specified time interval from a first time.

[0140] The technical problems to be solved in this disclosure are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this disclosure pertains.

[0141] The electronic device (101) described above may include at least one processor (210) including a processing circuit. The electronic device (101) may include an RF (radio frequency) transceiver (220). The electronic device (101) may include an RFFE (radio frequency front end) module (510) including a control circuit (520) and a power amplifier (530). The control circuit (520) may be configured to identify whether a first MIPI (mobile industry processor interface) command obtained from the at least one processor or the RF transceiver in a first slot is identical to a second MIPI command obtained in a second slot preceding the first slot. The control circuit (520) may be configured to refrain from generating a control signal for controlling the power amplifier based on the first MIPI command upon identification that the first MIPI command is identical to the second MIPI command. The control circuit (520) may be configured to transmit the control signal generated based on the first MIPI command to the power amplifier upon identification that the first MIPI command is different from the second MIPI command.

[0142] For example, the control circuit may be configured to refrain from transmitting the control signal to the power amplifier at a first time when the first MIPI command is acquired, upon identification that the first MIPI command is different from the second MIPI command. The control circuit may be configured to transmit the control signal to the power amplifier at a second time, which is after a specified time interval from the first time when the first MIPI command is acquired. The first time and the second time may be identified based on a clock signal corresponding to the first MIPI command.

[0143] For example, the control circuit may be configured to change the second MIPI command stored in the RFFE module to the first MIPI command upon identification that the first MIPI command is different from the second MIPI command.

[0144] For example, the control circuit may be configured to transmit a control signal to the power amplifier to control at least one parameter of the power amplifier, based on the identification that the first MIPI command is different from the second MIPI command.

[0145] For example, the RFFE module may include a low noise amplifier (LNA) and a second control circuit. The second control circuit may be configured to identify whether a third MIPI command obtained from the at least one processor or the RF transceiver is identical to a fourth MIPI command stored in the RFFE module. The second control circuit may be configured to refrain from generating a control signal to control the LNA based on the third MIPI command upon identifying that the third MIPI command is identical to the fourth MIPI command. The second control circuit may be configured to transmit the control signal generated based on the third MIPI command to the LNA upon identifying that the third MIPI command is different from the fourth MIPI command.

[0146] For example, the second time, which is after the specified time interval from the first time at which the first MIPI command was obtained, may not be included in the time interval allocated for the reference signal for decoding the data signal.

[0147] For example, the second time, which is after the specified time interval from the first time when the first MIPI command was acquired, may be included in the time interval to which the CP (cyclic prefix) of the data signal is assigned.

[0148] For example, the specified time interval can be identified based on the radio access technology (RAT) for the RFFE module.

[0149] The RFFE (radio frequency front end) module described above may include a control circuit. The RFFE module may include a power amplifier. The control circuit may be configured to identify whether a first MIPI (mobile industry processor interface) command obtained in a first slot from at least one processor of the electronic device or an RF (radio frequency) transceiver of the electronic device is identical to a second MIPI command obtained in a second slot preceding the first slot. The control circuit may be configured to refrain from generating a control signal for controlling the power amplifier based on the first MIPI command upon identifying that the first MIPI command is identical to the second MIPI command. The control circuit may be configured to transmit the control signal generated based on the first MIPI command to the power amplifier upon identifying that the first MIPI command is different from the second MIPI command.

[0150] For example, the control circuit may be configured to refrain from transmitting the control signal to the power amplifier at a first time when the first MIPI command is acquired, upon identification that the first MIPI command is different from the second MIPI command. The control circuit may be configured to transmit the control signal to the power amplifier at a second time, which is after a specified time interval from the first time when the first MIPI command is acquired. The first time and the second time may be identified based on a clock signal corresponding to the first MIPI command.

[0151] For example, the control circuit may be configured to change the second MIPI command stored in the RFFE module to the first MIPI command upon identification that the first MIPI command is different from the second MIPI command.

[0152] For example, the control circuit may be configured to transmit the control signal to the power amplifier for controlling at least one parameter of the power amplifier according to the identification that the first MIPI command is different from the second MIPI command.

[0153] For example, the RFFE module may include a low noise amplifier (LNA) and a second control circuit. The second control circuit may be configured to identify whether a third MIPI command obtained from the at least one processor or the RF transceiver is identical to a fourth MIPI command stored in the RFFE module. The second control circuit may be configured to refrain from generating a control signal to control the LNA based on the third MIPI command upon identifying that the third MIPI command is identical to the fourth MIPI command. The second control circuit may be configured to transmit the control signal generated based on the third MIPI command to the LNA upon identifying that the third MIPI command is different from the fourth MIPI command.

[0154] For example, the second time, which is after the specified time interval from the first time at which the first MIPI command was obtained, may not be included in the time interval allocated for the reference signal for decoding the data signal.

[0155] For example, the second time, which is after the specified time interval from the first time when the first MIPI command was obtained, may be included in the time interval to which the CP (cyclic prefix) of the data signal is assigned.

[0156] For example, the specified time interval can be identified based on the radio access technology (RAT) for the RFFE module.

[0157] The electronic device described above may include at least one processor including a processing circuit. The electronic device may include a radio frequency (RF) transceiver. The electronic device may include a radio frequency front end (RFFE) module including a control circuit and a power amplifier. The control circuit may be configured to obtain a mobile industry processor interface (MIPI) command from the at least one processor or the RF transceiver. The control circuit may be configured to refrain from generating a control signal for controlling the power amplifier based on the MIPI command at a first time when the MIPI command is obtained. The control circuit may be configured to transmit the control signal generated based on the MIPI command to the power amplifier at a second time, which is a specified time interval after the first time when the MIPI command is obtained.

[0158] For example, the control circuit may be configured to identify whether the MIPI command is identical to a second MIPI command stored in the RFFE module. The control circuit may be configured to refrain from generating the control signal based on the MIPI command upon identifying that the MIPI command is identical to the second MIPI command. The control circuit may be configured to transmit the control signal to the power amplifier at the second time, which is after the specified time interval from the first time at which the MIPI command was acquired, upon identifying that the MIPI command is different from the second MIPI command.

[0159] For example, the second time, which is after the specified time interval from the first time at which the MIPI command was obtained, may not be included in the time interval allocated for the reference signal for decoding the data signal. The second time, which is after the specified time interval from the first time at which the MIPI command was obtained, may be included in the time interval allocated for the CP (cyclic prefix) of the data signal.

[0160] For example, the specified time interval can be identified based on the radio access technology (RAT) for the RFFE module.
