Power control in new radio systems

An apparatus for wireless communication, comprising:

• means for determining a number of resource blocks for transmission of control information in an uplink control channel during a transmission time interval (TTI);
• means for determining a payload size of the control information;
• means for determining a number of resource elements of the resource blocks to be used for the control information;
• means for determining a transmit power for the uplink control channel during the TTI based at least in part on the number of resource elements of the resource blocks used for transmission of the control information and the payload size of the control information;
• and
• means for transmitting the control information on the uplink control channel during the TTI using the determined transmit power.

A mobile device for wireless communication, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the mobile device to:
• determine a number of resource blocks for transmission of control information in an uplink control channel during a transmission time interval (TTI);
• determine a payload size of the control information;
• determine a number of resource elements of the resource blocks to be used for the control information;
• determine a transmit power for the uplink control channel during the TTI based at least in part on the number of resource elements of the resource blocks used for transmission of the control information and the payload size of the control information;
• and
• transmit the control information on the uplink control channel during the TTI using the determined transmit power.

A non-transitory computer readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:

• determine a number of resource blocks for transmission of control information in an uplink control channel during a transmission time interval (TTI);
• determine a payload size of the control information;
• determine a number of resource elements of the resource blocks to be used for the control information;
• determine a transmit power for the uplink control channel during the TTI based at least in part on the number of resource elements of the resource blocks used for transmission of the control information and the payload size of the control information;
• and
• transmit the control information during the TTI using the determined transmit power.
