摘要： Systems and methods for performing power control of a physical channel in a communication system are provided. In one exemplary embodiment, a method in a wireless device of performing power control of a physical channel in a wireless communication system may include determining a transmission power for a transmission on the physical channel according to a power control loop. Further, the loop may specify the transmission power based on at least one parameter. Also, a value of the at least one parameter may be dependent on which of different transmission time interval (TTI) lengths defined as usable on the physical channel is selected for the transmission on the physical channel.

摘要： The present invention relates to a wireless access system supporting a full duplex radio (FDR) transmission environment. The method for a terminal to control uplink transmission power in a wireless access system supporting an FDR, according to an embodiment of the present invention, comprises the steps of: transmitting, to a terminal, power control information on uplink transmission power; and receiving an uplink signal transmitted on the basis of the power control information. The power control information may be determined on the basis of the maximum transmission power of the terminal, the open loop or closed loop power control factor, and a function having as a variable self-interference (SI) value of the base station due to the FDR.

摘要： A combined open loop and closed loop (channel quality indicator (CQI)-based) transmit power control (TPC) scheme with interference mitigation for a long term evolution (LTE) wireless transmit/receive unit (WTRU) is disclosed. The transmit power of the WTRU is derived based on a target signal-to-interference noise ratio (SINR) and a pathloss value. The pathloss value pertains to the downlink signal from a serving evolved Node-B (eNodeB) and includes shadowing. An interference and noise value of the serving eNodeB is included in the transmit power derivation, along with an offset constant value to adjust for downlink (DL) reference signal power and actual transmit power. A weighting factor is also used based on the availability of CQI feedback.

摘要： A method for a user equipment (UE) to determine a total power for transmissions in a cell group (CG) or a power for transmission of a channel or signal in a cell of a CG. The method comprises receiving configuration information for first and second CGs and for first and second maximum total powers for transmissions in the first and second CGs and determining first and second total powers for transmissions in the first and second CGs, respectively. The method also comprises receiving configuration information for a set of values for one or more parameters used to determine a power for transmission of a channel or signal in a cell of a CG and an indication for a value for each parameter from the one or more parameters.

摘要： The present disclosure relates to a transmitter for transmitting a transmit signal comprising a first signal portion and a second signal portion. The transmitter comprises a power amplifier configured to amplify the transmit signal. The power amplifier is prone to undesired gain variations during the first and the second signal portion. The transmitter further comprises a transmit feedback receiver coupled to an output of the power amplifier and configured to feed back the transmit signal to generate a fed back first signal portion and a fed back second signal portion. Processing circuitry is configured to determine a first gain relation between the fed back first signal portion and the first signal portion and to determine at least one second gain relation between the fed back second signal portion and the second signal portion. Power adjustment circuitry is configured to adjust a transmit power of the transmit signal according to a variation between the first gain relation and the second gain relation.
