Patent Images
1. A method of wireless communication, comprising:
- pre-preparing, at a transmitter, a plurality of candidate combined transmission waveforms of cross-carrier control information for one of at least one non-guaranteed transmission carriers and one or more of;
control information and data for a guaranteed transmission carrier;
receiving, at the transmitter, a transmission status for the at least one non-guaranteed transmission carriers;
selecting, by the transmitter, a transmission waveform from the plurality of candidate combined transmission waveforms based on the transmission status; and
transmitting, by the transmitter, the selected transmission waveform to a receiver.

Abstract
Management of transmitters is disclosed for conditions of transmission uncertainty that arises in operating over non-guaranteed transmission carriers that are required to perform listen-before-talk (LBT) processes and guaranteed transmission carriers that are LBT-exempt. Due to the hardware and software constraints, techniques are described to pre-prepare data and control transmissions or provide the transmitters additional time to prepare for such data and control transmissions based on the results of clear channel assessment (CCA) checks of the non-guaranteed transmission carriers.
