Abstract
A user equipment (UE) device may perform uplink (UL) data communication using a first radio access technology (RAT) while performing an UL voice call communication using a second RAT. The UL data communication may be supported by a first subscriber identity module (SIM) and the UL packet switched voice call communication may be supported by a second SIM. The UL voice call communication may be a packet switched communication. The communications may be performed by a radio(s) of the UE. The radio(s) may include shared physical layer resources that are shared between the UL data and UL voice communications. The UE may also include a single transmitter that may be shared between the UL data and UL packet voice communications and the UL data communication may use a first portion of the single transmitter's TTI and the UL voice communication may use a second portion of the single transmitter's TTI.
