Methods, systems, and devices for wireless communications are described for multiplexing of uplink channels in a shared radio frequency spectrum band. Techniques may provide for segmenting uplink resources into multiple different sets of uplink resources, each set of uplink resources having one or more associated uplink control channel resources. A base station or user equipment (UE) may select a set of uplink resources from the multiple sets of uplink resources for uplink transmissions from the UE based on a location of the uplink control channel resources of the set of uplink resources relative to other allocated uplink resources of the UE. Uplink control information (UCI) may be multiplexed with one or more uplink shared channel transmissions of a UE for transmission to a base station in certain circumstances.
