Method and apparatus for controlling carrier selection in wireless communications systems
First Claim
1. A method of assisting carrier access in a wireless communication system performed by a base station, which is configured to communicate data to and/or from at least two different types of terminal devices via a wireless access interface, the method comprising:
- broadcasting synchronisation signaling on a first carrier of the wireless access interface in a format that allows the two different types of terminal devices to synchronize with the first carrier to begin a camp-on procedure;
transmitting system information associated with a camp-on procedure on the first carrier of the wireless access interface, whereinat least a portion of the system information indicates to a first terminal device of the two different types of terminal devices whether the first terminal device is allowed to camp-on the first carrier.

Abstract
A mobile communications system including: at least one base station configured to communicate data to/from different terminal devices via respective of plural logically separate carriers of a wireless access interface; first and second terminal devices operable to camp-on to first and second carriers of plural carriers and to subsequently communicate data with the at least one base station via the first and second carriers. The first and second carriers support compatible synchronization signaling such that the first and second terminal devices both can synchronize with the first and second carriers to begin a camp-on procedure. Following synchronization with one of the first or second carriers to begin the camp-on procedure, the second terminal device is configured to determine whether or not to continue with the camp-on procedure in dependence on an aspect of physical layer signaling associated with a control channel of the carrier with which it has synchronized.

18. A non-transitory computer-readable medium including computer-readable instructions, which when executed by a base station configured to communicate data to and/or from at least two different types of terminal devices via a wireless access interface, cause the base station to:
-
broadcast synchronisation signaling on a first carrier of the wireless access interface in a format that allows the two different types of terminal devices to synchronize with the first carrier to begin a camp-on procedure; and transmit system information associated with a camp-on procedure on a first carrier of the wireless access interface, wherein at least a portion of the system information indicates to a first terminal device of the two different types of terminal devices whether the first terminal device is allowed to camp-on the first carrier.
