Methods, systems and apparatuses for operation in long-term evolution (LTE) systems are provided, including a method implemented in a base station. The method may include receiving, from a wireless transmit/receive unit (WTRU) via a first interface, a first message including radio capability information associated with the WTRU, transmitting, to a mobility management entity (MME) via a second interface, a second message including the radio capability information; receiving, from the MME via the second interface, a paging message requesting the WTRU be paged in idle mode, wherein the paging message includes the radio capability information associated with the WTRU; selecting, based on the radio capability information, a set of subframes to use for paging the WTRU in idle mode; and paging the WTRU in idle mode using the selected set of subframes.
