Abstract: The invention relates to a method for determining the transmission of a sounding reference signal (SRS) by a terminal in a wireless communication system, which can include a step of determining whether a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH) in a first timing advance (TA) group, or an SRS in a second TA group in the same subframe, is to be transmitted when the transmission timing of the PUCCH or the PUSCH in a cell of the first TA group and the transmission timing of the SRS in a cell of the second TA group overlap each other in the same subframe.

Abstract: In an example method, a mobile device connects a voice call for a user. The voice call causes one or more radio frequency transmitters of the mobile device to transmit radio waves at a first power level. Motion data describing movement of the mobile device is obtained, and the orientation of the mobile device is determined based on the motion data. A determination whether the mobile device is on the user's body or on an inanimate object is made based on the orientation of the mobile device over the period of time. The transmit power level is adjusted based on the determination.

Abstract: A high-frequency signal processing apparatus and a wireless communication apparatus can achieve a decrease in power consumption. For example, when an indicated power level to a high-frequency power amplifier is equal to or greater than a second reference value, envelope tracking is performed by causing a source voltage control circuit to control a high-speed DCDC converter using a detection result of an envelope detecting circuit and causing a bias control circuit to indicate a fixed bias value. The source voltage control circuit and the bias control circuit indicate a source voltage and a bias value decreasing in proportion to a decrease in the indicated power level when the indicated power level is in a range of the second reference value to the first reference value, and indicate a fixed source voltage and a fixed bias value when the indicated power level is less than the first reference value.

Abstract: Embodiments herein relate to a method for controlling transmit power of a mobile terminal. The method is performed by a mobile terminal (10) in a dual connectivity mode wherein the mobile terminal (10) is configured to support two or more contemporaneous links, including a first link and a second link, with two or more wireless network access points (12,13). The mobile terminal (10) independently calculates a respective unsealed uplink transmission power level for each link, based on a corresponding link-specific value. The mobile terminal (10) calculates a respective scaling factor for each link based on a total-power constraint and on one or more of the following: uplink resource allocation to each link, such that the scaling factor for the first link allocated more resources than the second link is larger than the scaling factor for the second link, link quality for each link, such that the scaling factor for the first link having a better link quality than the second link is larger than the scaling factor for the second link, uplink buffer state for each link, such that the scaling factor for the first link having more uplink data to be sent than the second link is larger than the scaling factor for the second link, and priority for each link, such that the scaling factor for the first link having a higher priority than the second link is larger than the scaling factor for the second link. The mobile terminal (10) further applies the respective scaling factor to each respective unsealed uplink transmission power level, to obtain corresponding scaled power levels. The mobile terminal (10) furthermore transmits over the two or more contemporaneous links at the respective scaled power levels.
