COOPERATION WITH DIGITAL FREQUENCY-TRANSLATION REPEATER FOR UPLINK TRANSMISSION AND RECEPTION-UE BEHAVIOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18141498 titled 'COOPERATION WITH DIGITAL FREQUENCY-TRANSLATION REPEATER FOR UPLINK TRANSMISSION AND RECEPTION-UE BEHAVIOR
Simplified Explanation
The patent application describes a method, computer-readable medium, and apparatus for transmitting baseband data signals from a user equipment (UE) to a base station via repeaters.
- The UE generates R layers of baseband data signals to be carried on N subcarriers.
- The UE maps each of the R layers of baseband data signals to N antennas in some or all of L first transmission time intervals.
- Each precoder used for mapping contains L*N elements.
- The UE transmits a first OFDM-based time-domain signal corresponding to the mapped baseband data signals across the L first transmission time intervals.
- The transmission is done via one or more repeaters.
- The L first transmission time intervals correspond to one second transmission time interval.
Original Abstract Submitted
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE generates R layers of baseband data signals to be carried on Nsubcarriers, where Nand R are positive integers. The UE maps each of the R layers of baseband data signals to Nantennas in some or all of L first transmission time intervals using R precoders, with each precoder containing L·Nelements, and Nand L being positive integers. The UE transmits a first OFDM-based time-domain signal corresponding to the mapped baseband data signals across the L first transmission time intervals to a base station via one or more repeaters, where the L first transmission time intervals correspond to one second transmission time interval.
