Abstract
A method and apparatus of receiving system information of an SeNB including configuring connection to an MeNB and receiving a RRC Connection Reconfiguration message including the system information of a cell included in a SCG controlled by the SeNB and a method of sharing frame offset between a MCG controlled by an MeNB and an SCG controlled by an SeNB connected to the MeNB through non-ideal backhaul including measuring system frame number (SFN) and subframe number (SN) of a cell included in the SCG and sharing the frame offset which is determined based on the SFN and the SN with the MeNB or the SeNB are provided.

Claim
1. A method of sharing, by a terminal, frame offset between a master eNodeB (MeNB) and a secondary eNodeB (SeNB), the method comprising:
receiving a measurement configuration for the SeNB via a radio resource control (RRC) signaling from the MeNB;
receiving a master information block (MIB) from a primary secondary cell (pSCell) of the SeNB;
measuring system frame number (SFN) of the SeNB through the MIB; and
transmitting a measurement report including a frame offset information which is determined based on the SFN of the SeNB to the MeNB,
wherein the MeNB and the SeNB provides dual connectivity to the terminal.
2. The method of claim 1, wherein the measurement report further includes a subframe boundary offset information which is determined based on subframe timings of the SeNB to the MeNB.
3. The method of claim 2,
wherein the subframe boundary offset information is determined by the difference between a point of time at which the terminal receives a start subframe from the MeNB and a point of time at which the terminal receives a start subframe from the SeNB.
4. The method of claim 1,
wherein the frame offset information is used for discontinuous reception (DRX) configuration.
5. The method of claim 1, wherein the frame offset information is used for a measurement gap configuration.
6. The method of claim 1, further comprising:
receiving RRC Connection Reconfiguration message for adding the cell of the SeNB from the MeNB; and
transmitting RRC Connection Reconfiguration Complete message to the MeNB.
7. The method of claim 1, wherein the measurement report further includes a radio frame boundary offset information which is determined based on subframe timings of the SeNB to the MeNB.
8. The method of claim 7, wherein the radio frame boundary offset is determined by the difference between a point of time at which the terminal receives a start radio frame from the MeNB and a point of time at which the terminal receives a start radio frame from the SeNB.
9. A method of sharing, by a master eNodeB (MeNB), frame offset between the MeNB and a secondary eNodeB (SeNB), the method comprising:
transmitting a measurement configuration for the SeNB via a radio resource control (RRC) signaling to a terminal; and
receiving an measurement report including a frame offset information which is determined based on a system frame number (SFN) measured by the terminal,
wherein the SFN is measured through a master information block (MIB) received from a primary secondary cell (pSCell) by the terminal, the MeNB and the SeNB provides dual connectivity to the terminal.
10. The method of claim 9, wherein the measurement report further includes a subframe boundary offset information which is determined based on subframe timings of the SeNB and the MeNB by the terminal.
11. The method of claim 10, wherein the server; and
subframe boundary offset information is determined by the difference between a point of time at which the terminal receives a start subframe from the MeNB and a point of time at which the terminal receives a start subframe from the SeNB.
12. The method of claim 9,
wherein the frame offset information is used for discontinuous reception (DRX) configuration.
13. The method of claim 9, wherein the frame offset information is used for a measurement gap configuration.
14. The method of claim 9, wherein the measurement report further includes a radio frame boundary offset which is determined based on subframe timings of the SeNB to the MeNB.
15. The method of claim 14, wherein the radio frame boundary offset is determined by the difference between a point of time at which the terminal receives a start radio frame from the MeNB and a point of time at which the terminal receives a start radio frame from the SeNB.
