Abstract
Methods and apparatuses are disclosed for multiplexing uplink control information and uplink user data in the same uplink slot. A scheduling entity may use a unified rule to map uplink control information (UCI) in a distributed fashion according to a predetermined step size on each orthogonal frequency division multiplexing (OFDM) symbol regardless of UCI types. The scheduling entity may use a unified rule to partition the UCI into two parts when frequency hopping is enabled, and use the same unified rule to map the UCI in each hop.

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 (REs) 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 REs of one or more corresponding orthogonal frequency division multiplexing (OFDM) symbols of the PUSCH;
- and
- transmitting data in the PUSCH including the UCI.
An apparatus comprising:
- a communication interface configured for wireless communication;
- and
- a communication circuit configured to:
- modulate uplink control information (UCI) comprising a plurality of control information types, to generate a plurality of modulated UCI symbols;
- map the plurality of modulated UCI symbols to a plurality of resource elements (REs) 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 REs of one or more corresponding orthogonal frequency division multiplexing (OFDM) symbols of the PUSCH;
- and
- transmit data in the PUSCH including the UCI using the communication interface.
A wireless communication apparatus comprising:
