1. A user equipment (UE), comprising:
a transceiver configured to wirelessly communicate with a base station; and
a processor communicatively coupled to the transceiver and configured to:
determine, based at least in part on a nominal repetition configuration received from the base station, a single symbol is an orphan symbol in a physical uplink shared channel (PUSCH) repetition Type B transmission in a Time Division Duplexing (TDD) New Radio (NR) communication system, wherein the orphan symbol is contained in a first actual repetition of size of one symbol that is either an uplink symbol or a flexible symbol, and the first actual repetition is a part of a nominal repetition that is segmented into multiple actual repetitions including the first actual repetition having the orphan symbol and a second actual repetition having multiple consecutive symbols separated from the first actual repetition by one or more downlink symbols defined by a subframe indicator (SFI) or an invalid symbol pattern;
determine a filler symbol to replace the orphan symbol in the PUSCH repetition Type B transmission; and
generate the PUSCH repetition Type B transmission including the filler symbol.
