TECHNIQUES FOR A COMBINED CYCLIC PREFIX AND GUARD INTERVAL-BASED WAVEFORM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17378568 titled 'TECHNIQUES FOR A COMBINED CYCLIC PREFIX AND GUARD INTERVAL-BASED WAVEFORM
Simplified Explanation
Methods, systems, and devices for wireless communication are described in this patent application. The innovation involves a combined cyclic prefix and guard interval-based waveform format for communication between a user equipment (UE) and a base station. The base station transmits control signaling to the UE, indicating a slot configuration. The UE identifies the format of a slot, which includes a set of symbols, based on the slot configuration. The format specifies that the first portion of the first symbol in the set includes at least two cyclic prefixes, while the second portion includes a guard interval. The UE and the base station can then perform wireless communications during the first symbol according to this format.
- The patent application describes a method for wireless communication using a combined cyclic prefix and guard interval-based waveform format.

Original Abstract Submitted
Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may communicate according to a combined cyclic prefix and guard interval-based waveform format. The base station may transmit control signaling to the UE. The control signaling may indicate a slot configuration. The UE may identify a format of a slot including a set of symbols based on the slot configuration. The format may indicate that a first portion of a first symbol of the set of symbols includes at least two cyclic prefixes and a second portion of the first symbol includes a guard interval. The UE and the base station may perform wireless communications during the first symbol in accordance with the format.
