This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for determining time location of sub-band full duplex. A
user equipment, UE (102), receives (602), from a
radio access network, RAN, node (104), a configuration including a time-division duplex, TDD, pattern. The UE (102) receives (604), from the RAN node (104), a sub-band full duplex, SBFD, pattern indicating symbols in the TDD pattern configured for a SBFD operation. The UE (102) transmits (612), to the RAN node (104), an uplink, UL, transmission on an assigned symbol configured for the SBFD operation corresponding to the SBFD pattern, the assigned symbol being associated with a non-UL symbol of the TDD pattern.
