Abstract:
1. A method of operating a wireless relay device, the method comprising: establishing a first connection between a relay node (RN) and a base station using a first set of frequency bands, wherein establishing the first connection comprises establishing a primary cell (PCell) connection between the RN and the base station using an out of band (OOB) carrier; establishing a second connection between the RN and a user device using the first set of frequency bands; and establishing a third connection between the RN and the base station using a second set of frequency bands, wherein establishing the third connection comprises establishing a secondary cell (SCell) connection between the RN and the base station using an in-band (IB) carrier after establishing the PCell connection with the base station, and wherein the base station configures the SCell connection to carry control information from the RN to the base station, the control information being excluded from the PCell connection-when the base station configures the SCell connection to carry the control information.
