Abstract
Certain aspects of the present disclosure relate to methods and apparatus for determining spectral efficiency for transmitting uplink control information (UCI) on an uplink data channel for use in performing uplink power control.
Claims36
A method for wireless communications by a user equipment (UE), comprising:
- receiving information indicative of a modulation coding scheme (MCS) for use by the UE to transmit uplink control information (UCI) on an uplink data channel;
- determining a spectral efficiency for transmitting the UCI based at least in part on the MCS and on a rate offset between a rate for transmitting UCI and a rate for transmitting uplink data on the uplink data channel;
- performing uplink power control based at least in part on the determined spectral efficiency;
- and
- transmitting the UCI without uplink data on the uplink data channel using an uplink power based at least in part on the performed uplink power control.
2 more elements
An user equipment (UE) configured for wireless communication, comprising:
- a memory;
- and
- a processor communicatively coupled to the memory, wherein the processor is configured to:
- receive information indicative of a modulation coding scheme (MCS) for use by the UE to transmit uplink control information (UCI) on an uplink data channel;
- determine a spectral efficiency for transmitting the UCI based at least in part on the MCS and on a rate offset between a rate for transmitting UCI and a rate for transmitting uplink data on the uplink data channel;
- perform uplink power control based at least in part on the determined spectral efficiency;
- and
- transmit the UCI without uplink data on the uplink data channel using an uplink power based at least in part on the performed uplink power control.

An apparatus, comprising:
- means for receiving information indicative of a modulation coding scheme (MCS) for use by the apparatus to transmit uplink control information (UCI) on an uplink data channel;
- means for determining a spectral efficiency for transmitting the UCI based at least in part on the MCS and on a rate offset between a rate for transmitting UCI and a rate for transmitting uplink data on the uplink data channel;
- means for performing uplink power control based at least in part on the determined spectral efficiency;
- and
- means for transmitting the UCI without uplink data on the uplink data channel using an uplink power based at least in part on the performed uplink power control.

A non-transitory computer-readable storage medium that stores instructions that when executed by a processor of a user equipment (UE) cause the UE to perform a method of wireless communication, comprising:
- receiving information indicative of a modulation coding scheme (MCS) for use by the UE to transmit uplink control information (UCI) on an uplink data channel;
- determining a spectral efficiency for transmitting the UCI based at least in part on the MCS and on a rate offset between a rate for transmitting UCI and a rate for transmitting uplink data on the uplink data channel;
- performing uplink power control based at least in part on the determined spectral efficiency;
- and
- transmitting the UCI without uplink data on the uplink data channel using an uplink power based at least in part on the performed uplink power control.
