Methods, systems and apparatuses for operation in long-term evolution systems
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.
1. A method implemented in a base station, the method comprising:
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.
2. The method of claim 1 , further comprising:
paging the WTRU in a cell on condition that the cell supports paging the WTRU in accordance with the radio capability information.
3. The method of claim 2 , further comprising:
determining that the cell supports paging the WTRU in accordance with the radio capability information.
4. The method of claim 1 , wherein the first interface is a radio resource control (RRC) interface.
5. The method of claim 1 , wherein the second interface is a S1 interface.
6. The method of claim 1 , wherein the first message is a radio resource control (RRC) message.
7. The method of claim 1 , wherein the second message is a S1 WTRU CAPABILITY INFO INDICATION message.
8. The method of claim 1 , wherein the paging message is an S1 PAGING message.
9. A base station comprising a receiver, transmitter and a processor, wherein:
the receiver is configured to receive, from a wireless transmit/receive unit (WTRU) via a first interface, a first message including radio capability information associated with the WTRU;
the transmitter is configured to transmit, to a mobility management entity (MME) via a second interface, a second message including the radio capability information;
the receiver is configured to receive, 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;
the processor is configured to select, based on the radio capability information, a set of subframes on which to page the WTRU in idle mode; and
the processor in combination with the transmitter are configured to page the WTRU in idle mode using the selected set of subframes.
10. The base station of claim 9 , wherein the processor in combination with the transmitter are configured to:
page the WTRU in a cell on condition that the cell supports paging the WTRU in accordance with the radio capability information.
11. The base station of claim 10 , wherein the processor is configured to:
determine that the cell supports paging the WTRU in accordance with the radio capability information.
12. The base station of claim 9 , wherein the first interface is a radio resource control (RRC) interface.
13. The base station of claim 9 , wherein the second interface is a S1 interface.
14. The base station of claim 9 , wherein the first message is a radio resource control (RRC) message.
