The present disclosure relates to a CDMA communication node arrangement comprising at least two spatially separated antenna units, at least one radio unit and at least one control unit. Each antenna unit has at least one corresponding coverage area and is connected to the central unit. The control unit is arranged to alter transmitting properties of at least a first antenna unit, to a user terminal, such that more or less power is transmitted by the first antenna unit in a dedicated channel. The control unit is arranged to monitor received inner power control loop commands when at least a second antenna unit is communicating with the user terminal, and to determine whether said first antenna unit should start or stop communicating with the user terminal, or continue as before, based on how the inner power control loop commands respond. The present disclosure also relates to a corresponding method.

A method for transmitting physical uplink shared channel (PUSCH) and a user equipment (UE) are provided. In the method, a configuration of a first PUSCH with a number of PUSCH repetitions is received. Physical Downlink Control Channel (PDCCH) which includes a Transmit Power Control (TPC) command is received. Whether the PDCCH is received within a number of symbols before a first symbol of a slot bundle is determined. In response to determining the PDCCH is received within the number of symbols before the first symbol of the slot bundle, the TPC command is applied for a first PUSCH transmission occasion within the slot bundle. In response to determining the PDCCH is not received within the number of symbols before the first symbol of the slot bundle, the TPC command is applied for a second PUSCH transmission occasion within a second slot bundle after the slot bundle.

A method and device for determining power control configuration. it is determined whether a first transmit power control configuration based on a first uplink transmission is outdated; and a second transmit power control configuration for a second uplink transmission is determined based on a power control scheme. Therefore, transmit power control efficiency of sparse data transmissions may be improved.

A user equipment (UE) receives a parameter indicating a power control loop out of a plurality of power control loops and a first transmit power control (TPC) command. The UE transmit a first uplink physical channel based on the first TPC command and the indicated power control loop. Further, the UE receive a single downlink channel, wherein the single downlink channel carries a channel allocation and a second TPC command for the UE. The UE transmit a second uplink physical channel using resources based on the channel allocation and at a transmission power level based on the second TPC command.

A user terminal is disclosed including a receiver, a transmitter, and a processor. The receiver receives downlink control information including a transmission power control (TPC) command. The transmitter transmits an uplink signal using a transmission power that is controlled based on an accumulated value of the TPC command, accumulated independently of a length of a transmission duration of the uplink signal. The processor resets the accumulated value if a predetermined parameter is provided by higher layer signaling. In other aspects, a radio base station and a radio communication method for a user terminal are also disclosed.

Aspects of the disclosure relate to a method of wireless communication at a user equipment (UE), including determining that future or past simultaneous first and second signal transmissions by first and second transceivers pursuant to a dual subscription dual active (DSDA) mode of operation may exceed or has exceeded a maximum allowed transmit power, respectively; and performing at least one operation to reduce an occurrence, likelihood or frequency of the future simultaneous first and second signal transmissions exceeding the maximum allowed transmit power in the DSDA mode of operation, respectively.

Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal is configured to effectively ignore “UP” transmit power control commands in the event that the mobile terminal is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal, a plurality of transmit power control commands are received. An accumulated power control value is adjusted in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal is not in a power-limited state. Transmit power settings for each transmission are calculated based on the accumulated power control value and the one or more radio link parameters.

Systems, devices, and techniques for transmit power control (TPC) in wireless communication systems are described. A described technique performed by a user equipment (UE) includes signaling that enables transmit power control (TPC) accumulation; receiving, by the UE, downlink control information (DCI) messages corresponding to respective physical uplink shared channel (PUSCH) transmission occasions; determining, by the UE, power control adjustment states for the PUSCH transmission occasions; and transmitting, by the UE, in the PUSCH transmission occasions in accordance with the power control adjustment states. Determining the power control adjustment states can include selectively applying TPC accumulation to one or more of the power control adjustment states based on a determination that at least one of the PUSCH transmission occasions is out-of-order based on an arrival ordering of the DCI messages.

Provided in one embodiment of the present specification is a wireless communication device. The wireless communication device can comprise a transceiver, a memory for storing a command, and a processor. An operation performed on the basis of the execution of the command by the processor can comprise the steps of: determining transmission power; and controlling the at least one transceiver so as to transmit, on the basis of the transmission power, an uplink signal in an operating band including 39 GHz.

Systems and methods are provided for dynamically reallocating available transmit power on a dual connectivity user device. A retransmission rate is monitored for the user device that can simultaneously communicate using two or more wireless communication protocols. It is determined that the retransmission rate for the user device is above a threshold for communications using a first wireless communication protocol, such as LTE. Channel assignment of a second wireless communication protocol, such as 5G, is reduced, thus allowing the user device to reallocate a portion of the transmit power previously allocated for the second wireless communication protocol to the first wireless communication protocol to improve the retransmission rate for the first wireless communication protocol.
