Description

Uplink transmission power control method and electronic device therefor

Embodiments disclosed in this document relate to an uplink transmission power control method and an electronic device therefor.

Voice over IP (VoIP) technology based on Internet Protocol (IP) is widely used to improve the quality and efficiency of voice calls through circuit switched (CS) networks. Unlike the circuit-switching method, in VoIP technology, voice can be exchanged through data packets, and a VoIP call can be referred to as a packet-based voice call. When an electronic device uses packetized voice data, efficiency of data capacity and quality of voice data may be increased. VoIP technology can be applied to various network platforms based on packet data networks. For example, for VoIP in long term evolution (LTE) communication, voice over LTE (VoLTE) may be used.

In a packet-based voice call (eg, VoLTE) in LTE communication, an electronic device may determine uplink transmission power based on a transmission power indicated by a base station or a channel state. For example, the electronic device may increase the probability that the signal to be transmitted is received by the base station by transmitting the uplink signal using high transmission power.

If the transmission power is increased, the probability of successful reception at the receiving end of the transmission signal may increase, but power consumption of the electronic device and interference with other electronic devices may also increase. Accordingly, the electronic device may transmit an uplink signal with appropriate transmit power by using transmit power control information received from the base station (eg, a transmit power control (TPC) command). An increase in transmission power may cause an increase in the intensity of electromagnetic waves due to signal transmission. Therefore, in order to reduce the influence of electromagnetic waves on a user, the transmission power can be reduced to a specified transmission power.

When transmission power is reduced in consideration of body absorption rate of electromagnetic waves, at least a part of transmission packets of a packet-based voice call may not be successfully received by a receiving end. For example, a call mute phenomenon and/or a call drop phenomenon may occur due to packet loss. The silent call phenomenon may refer to a phenomenon in which voice received by an electronic device is not transferred to another electronic device or voice transmitted by another electronic device is not received by the electronic device. A call dropping phenomenon may refer to a phenomenon in which a voice call is terminated against a user's intention.

According to various embodiments, in operation 415, when performing uplink transmission, the electronic device 201 may determine uplink transmission power based on at least the amount of allocated uplink resources. According to an embodiment, the electronic device 201 may determine uplink transmission power based on the amount of uplink resources allocated to uplink signals. For example, when the number of allocated uplink resource blocks indicated by the uplink resource information included in the uplink allocation received from the first base station 202 exceeds the specified number, the electronic device 201 first transmits power. (eg, about 24.5 dBm), and if the number of allocated uplink resource blocks is less than or equal to the specified number, the uplink signal may be transmitted with a second transmit power higher than the first transmit power. For example, the second transmit power (eg, about 25 to 25.2 dBm) may be transmit power obtained by adding a specified offset to the first transmit power.

For example, a resource block is a unit of radio resources defined in cellular mobile communication, and the first base station 202 may perform scheduling in units of resource blocks. According to an embodiment, a resource block may correspond to 12 subcarrier spacings on the frequency axis and one time slot on the time axis. For example, two time slots on the time axis may constitute one subframe. For example, one time slot may correspond to one half-subframe. A resource block may be referred to as a physical resource block or a virtual resource block. For example, the first base station 202 may instruct the electronic device 201 the number of resource blocks per time slot corresponding to 1 TTI by transmitting the number of resource blocks per time slot to the electronic device 201. .

According to various embodiments, the first base station 202 may allocate uplink resources in units of 1 transmit-time-interval (TTI). For example, 1 TTI may correspond to a time interval of one subframe. For example, the number of uplink resource blocks indicated by the uplink grant may mean the number of uplink resource blocks per time slot allocated to the electronic device 201 in a subframe corresponding to the uplink grant. For example, when the uplink grant indicates 4 resource blocks, the electronic device 201 provides radio resources with bandwidths corresponding to the 4 resource blocks in each time slot of a subframe corresponding to the uplink grant. Uplink transmission can be performed using In the following description, the number of allocated resource blocks may refer to the number of resource blocks configured per time slot within a corresponding TTI.

When the time interval T1 corresponds to 2 subframes (eg, 4 time slots), the number of resource blocks allocated to the electronic device 201 during the time interval T1 may be 28 in total. In this case, the number of resource blocks allocated to the electronic device 201 exceeds the designated number of resource blocks. Accordingly, in period T1, the electronic device 201 may transmit an uplink signal to the first base station 202 with the first transmission power. For example, data transmitted in interval T1 may be data packets excluding voice data packets.

According to an embodiment, in time interval T2, the number of resource blocks allocated to the electronic device 201 may correspond to 3 or 2 resource blocks in the frequency domain. When time interval T2 corresponds to 2 subframes (eg, 4 time slots), the number of resource blocks allocated to the electronic device 201 during the first subframe of time interval T2 is 6, and time interval T2 The number of resource blocks allocated to the electronic device 201 during the second subframe may be 4. In this case, the number of resource blocks allocated to the electronic device 201 is less than or equal to the specified number of resource blocks. Accordingly, in period T2, the electronic device 201 may transmit an uplink signal to the first base station 202 with the second transmission power. For example, the second transmit power may be a higher transmit power than the first transmit power. The second transmit power may be a value obtained by adding a specified offset to the first transmit power. For example, the first transmit power may be an initial limit transmit power set in the electronic device 201 . For example, data transmitted in section T2 may include a voice data packet.

According to an embodiment, the first transmit power and the second transmit power may correspond to transmit power lower than the third transmit power. For example, the third transmit power may correspond to the maximum transmit power of the communication circuit 290 of the electronic device 201 .

Corresponds to transmission power (eg, first transmission power), and P _initial +offset may correspond to power obtained by adding an offset to the initial limited transmission power (eg, second transmission power). For example, the offset may be at least 0.1 dBm or greater. The electronic device 201 may be set to control the offset in units of 0.1 dBm. For example, the electronic device 201 may transmit an uplink signal with a lower transmit power between the third transmit power and the second transmit power.
