SIGNALING FOR ENABLING FULL-DUPLEX COMMUNICATIONS IN THE PRESENCE OF A TIMING ADVANCE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17851410 titled 'SIGNALING FOR ENABLING FULL-DUPLEX COMMUNICATIONS IN THE PRESENCE OF A TIMING ADVANCE
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communication. It focuses on a user equipment (UE) receiving a control signal that allocates downlink and uplink resources. The UE generates an uplink signal containing feedback control information and cancelation tones to eliminate interference with the downlink signal. The UE can also generate an uplink signal with feedback control information, uplink symbols, and cyclic extensions based on a timing advance value. The UE transmits the uplink signal while receiving downlink data on the allocated uplink resources.
- The patent application focuses on wireless communication systems and devices.

Original Abstract Submitted
Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may receive a control signal allocating downlink resources and uplink resources, where the uplink resources puncture the downlink resources and are allocated for transmitting feedback control information. The UE may generate an uplink signal containing the feedback control information and one or more cancelation tones for canceling interference between a downlink signal and the uplink signal in accordance with a timing advance value. Additionally, or alternatively, the UE may generate an uplink signal including the feedback control information, where the uplink signal contains uplink symbols and cyclic extensions appended to the uplink symbols, and the cyclic extensions may be based on the timing advance value. The UE may transmit, while receiving downlink data on the downlink resources, the uplink signal including the feedback control information using the set of uplink resources.
