A user equipment (UE) receives a reference signal from a base station and determines a pathloss based on the received reference signal. The UE further receive a downlink channel signal including an uplink resource assignment and a transmit power command. The UE transmits an uplink signal, wherein the uplink signal is transmitted using a transmit power level determined based on the pathloss, a format of the uplink signal, the uplink resource assignment and the transmit power command.

A base station can prevent deterioration of data channel application control accuracy due to influence of transmission power control to a control channel. In the base station, each encoding section performs encoding processing to an SCCH (Shared Control Channel) of each mobile station, each modulating section performs modulation processing to the encoded SCCH, an arranging section arranges the SCCH to each mobile station to one of a plurality of subcarriers which configure an OFDM symbol, and transmission power control section controls transmission power of the SCCH based on reception quality information reported from each mobile station. The arranging section arranges a plurality of the SCCH to be under transmission power control to one of the subcarriers so that combinations at resource blocks are the same.

In order to appropriately control each use case even when a plurality of use cases having different requirements coexists in a radio communication system, a user terminal according to one aspect of the present disclosure has a transmitting section that performs UL transmission using at least one of a first modulation and coding scheme (MC table or a second MCS table in which a code rate lower than a minimum code rate specified in the first MCS table is specified, and a control section that separately controls transmission conditions for the UL transmission according to a type of an MCS table to be applied.

A wireless communication device receives an average transmission power limit for a time period, and determines a first MTPL for a first time of the time period by setting the first MTPL to the average transmission power limit. The wireless communication device then transmits a signal at the first time using a first transmission power not to exceed the first MTPL. If the first transmission power is less than the first MTPL, then the wireless communication device determines residual transmission power based on a difference between the first MTPL and the first transmission power. The wireless communication device determines a second MTPL for a second time of the time period by adding the residual transmission power to the first MTPL. The wireless communication device then transmits a signal at the second transmission power not to exceed the second MTPL.

A wireless device receives a radio resource control (RRC) release message indicating a small data transmission (SDT) time window for an SDT in an RRC inactive state. The wireless device transmits, during the SDT time window, an initial uplink transmission using a first power control adjustment (PCA) state being reset to zero. The wireless device transmits, using a second PCA state, a second uplink transmission. In response to the second uplink transmission being subsequent to the initial uplink transmission during the SDT time window, the second PCA state is based on the first PCA state and one or more transmit power control command values received during the SDT time window.

A user equipment (UE) is provided to implement a set of transmit power control (TPC) commands during a time domain window (TDW) including multiple physical uplink shared channel (PUSCH) transmissions. The UE can receive a configuration from the base station to configure the UE to support a power control mode and a timeline measurement related to a PUSCH transmission. The UE can receive a set of TPC commands during the TDW, determine whether a TPC command of the set of TPC commands satisfies a time constraint based on the timeline measurement, determine an effective TPC command for the set of TPC commands based on one or more TPC commands satisfying the time constraint, determine an effective delay for the effective TPC command based on the timeline measurement, and further apply the effective TPC command to a PUSCH transmission determined based on the effective delay of the effective TPC command.

A method for adjusting a transmitting (TX) power ratio of a radio module includes: separating multiple radio modules into multiple radio groups according to a radiofrequency (RF) regulation, wherein the multiple radio modules comprise the radio module; mapping an RF exposure limit to a TX power limit; interacting with at least one other radio module for adjusting the TX power ratio, to obtain at least one adjusted TX power ratio, wherein the radio module and the at least one other radio module are comprised in a same radio group of the multiple radio groups; and adjusting the TX power limit according to the at least one adjusted TX power ratio, to generate an adjusted TX power limit of the radio module.

A user equipment (UE) receives a transmit power control (TPC) command and is configured to accumulate the TPC command with prior TPC commands to derive a first value. Further, the UE is configured to produce a second value based on a type of a first signal to be transmitted and a third value based on a transport format of the first signal, wherein the type of signal is from a plurality of types of signals having different spreading factors. The UE is configured to determine a transmission power level for the first signal based on the first value, the second value and the third value. The UE is configured to transmit the first signal at the determined transmission power level.

In some embodiments a method performed by a wireless device for controlling power for an UL control channel includes receiving a first transmit power control (TPC) command; receiving at least a second TPC command; computing a power for the UL control channel transmission based on at least the first TPC command and the second TPC command; and adjusting a power for the UL control channel according to the computed power. In this way, the wireless device behavior is clarified in terms of UL power setting in case multiple transmissions with feedback in the same UL transmission are scheduled, especially if these multiple transmissions are scheduled at different times.
