Segmented pre-compensation schemes for time division duplexing in a non-terrestrial network

Abstract

Methods, systems, and devices for wireless communication are described. Various aspects generally relate to segmented pre-compensation schemes that account for time division duplexing (TDD) patterns involving periodic valid uplink subframes. Some aspects more specifically relate to a segmented pre-compensation scheme according to which a user equipment (UE) may reset a segment duration in a next valid uplink subframe in accordance with an interruption, by an invalid uplink subframe associated with a TDD pattern, of a segment within a prior valid uplink subframe. The UE may perform a time or frequency adjustment at or prior to the segment duration reset in the next valid uplink subframe. For example, if a first segment is interrupted by an invalid uplink subframe, the UE may transmit a postponed portion of the uplink message within a next valid uplink subframe in accordance with a new time or frequency adjustment.
