Mapping uplink control information to uplink data channel in wireless communication

A method of wireless communication, comprising:

• modulating uplink control information (UCI) comprising a plurality of control information types, to generate a plurality of modulated UCI symbols;
• mapping the plurality of modulated UCI symbols to a plurality of resource elements of a physical uplink shared channel (PUSCH) such that the modulated UCI symbols of each control information type are distributed according to a predetermined step size among the resource elements of one or more corresponding orthogonal frequency division multiplexing (OFDM) symbols of the PUSCH, the mapping comprising:
• dividing the modulated UCI symbols into a first partition and a second partition, and
• mapping the first partition to resource elements of the plurality of resources elements in a first frequency band and the second partition to resource elements of the plurality of resources elements in a second frequency band;
• and
• transmitting the PUSCH, including the plurality of resource elements to which the modulated UCI symbols were mapped and including resource elements to which data is mapped, using frequency hopping across the first frequency band and the second frequency band.

An apparatus comprising:

• a communication interface configured for wireless communication;
• and
• a communication circuit configured to:
• modulate uplink control information (UCI) of a plurality of control information types to generate a plurality of modulated UCI symbols, each modulated UCI symbol carrying UCI of a corresponding one of the control information types;
• map the plurality of modulated UCI symbols to a plurality of resource elements of a plurality of orthogonal frequency division multiplexing (OFDM) symbols of a physical uplink shared channel (PUSCH), the mapping comprising, for each of the control information types, distributing the respective modulated UCI symbols to resource elements of one or more corresponding OFDM symbols of the plurality of OFDM symbols based on a step size between adjacent ones of the respective resource elements for each respective OFDM symbol, the step size for the respective OFDM symbol being a function of a number of available resource elements in the respective OFDM symbol and a number of remaining modulated UCI symbols of the respective control information type;
• and
• transmit the PUSCH including the plurality of resource elements to which the modulated UCI symbols were mapped.
