Description

Uplink transmission power control method and electronic device for same

Embodiments disclosed in the present disclosure 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 voice quality and efficiency of voice calls over circuit switched (CS) networks. Unlike the circuit switched scheme, in the VoIP technology, voice may be exchanged through a data packet, and a VoIP call may be referred to as a packet based voice call. As the electronic device uses packetized voice data, efficiency of data capacity and voice data quality 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, the electronic device may determine an uplink transmission power based on a transmission power or a channel state indicated by the base station. For example, the electronic device may increase the probability that a signal to be transmitted is received at the base station by transmitting an uplink signal using a high transmission power.

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

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

According to various embodiments, in operation 420, the electronic device 201 may receive a response to the uplink transmission from the first base station 202. For example, the electronic device 201 may receive a response from the first base station 202 through a physical hybrid-ARQ indicator channel (PHICH). For example, the response may include an acknowledgment (ACK) or negative acknowledgment (NACK) for the uplink transmission. According to an embodiment, the electronic device 201 may determine retransmission of the uplink transmission based on the response.

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

For example, the 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, the resource block may correspond to twelve subcarrier spacings on the frequency axis and correspond to 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. Resource blocks may be referred to as physical resource blocks or virtual resource blocks. For example, the first base station 202 may instruct the electronic device 201 of the number of resource blocks per time slot corresponding to one 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 one transmit-time-interval (TTI). For example, one 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 four resource blocks, the electronic device 201 may transmit a radio resource having a bandwidth corresponding to four resource blocks in each of the time slots of the subframe corresponding to the uplink grant. Uplink transmission can be performed by using. In the following description, the number of allocated resource blocks may refer to the number of resource blocks set for each time slot in a corresponding TTI.

When the time interval T1 corresponds to two subframes (eg, four time slots), the number of resource blocks allocated to the electronic device 201 during the time interval T1 may be a total of 28. In this case, the number of resource blocks allocated to the electronic device 201 exceeds the number of specified resource blocks. Therefore, in the period T1, the electronic device 201 may transmit the uplink signal to the first base station 202 at the first transmission power. For example, the data transmitted in the section T1 may be a data packet except for a voice data packet.

According to an embodiment, in the time interval T2, the number of resource blocks allocated to the electronic device 201 may correspond to three or two resource blocks on the frequency domain. If time interval T2 corresponds to two subframes (eg, four time slots), the number of resource blocks allocated to electronic device 201 during the first subframe of time interval T2 is 6, and The number of resource blocks allocated to the electronic device 201 during the second subframe may be four. In this case, the number of resource blocks allocated to the electronic device 201 is equal to or less than the specified number of resource blocks. Therefore, in the period T2, the electronic device 201 may transmit the uplink signal to the first base station 202 at the second transmission power. For example, the second transmit power may be a transmit power higher 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 initial limit transmit power set in the electronic device 201. For example, the data transmitted in the section T2 may include a voice data packet.

According to one embodiment, the first transmit power and the second transmit power may correspond to a 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. In FIG. 5, the second transmit power is shown at a lower value than the third transmit power, but embodiments of the present disclosure are not limited thereto.

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