Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication between a user equipment (UE) and a base station. The UE monitors for a wake-up signal (WUS) within a WUS monitoring window based on a jitter monitoring window associated with jittered data traffic at a base station. The base station transmits, to the UE, the WUS. The UE determines whether the WUS is received within the WUS monitoring window. The UE detects a semi-persistent scheduling (SPS) occasion following a location of the WUS by an offset based on the WUS being received within the WUS monitoring window. The base station transmits, to the UE, in the SPS occasion following the WUS by the offset, a physical downlink shared channel including a data frame of the jittered data traffic.

For example, a UE can report to a BS at least one of an indication of a UL Tx switching time and an uplink data preparation time of the UE. In return, the UE can receive an indication of uplink scheduling from the BS, which the UE can use to communicate with the BS.
