Abstract
A method and apparatus are disclosed for reducing signaling and delay for uplink scheduling in a wireless communication network. The method includes activating a newly configured SCell (Secondary Cell). The method also includes starting a TA (Timing Alignment/Advance) timer associated with the SCell upon detection of a specific DL (Downlink) signaling. The method further includes detecting and processing a PDCCH (Physical Downlink Control Channel) for a PUSCH (Physical Uplink Shared Channel) transmission. In addition, the method includes sending a MAC (Mac Access Control) PDU (Protocol Data Unit) corresponding to the PDCCH scheduling on a PUSCH of the SCell based on an UL transmission timing equal to a specific value.
