Abstract
Embodiments provide methods, apparatuses, and software for transmitting or receiving information on at least one coverage carrier and/or at least one capacity carrier of a multi-carrier cell.
Claims16
An apparatus, configured to
- access a multi-carrier cell,
- receive system information or broadcast system information, and
- select at least one carrier based on the received information.
Apparatus, configured to
- provide or broadcast at least one of a coverage carrier, a capacity carrier, and system information of a multi-carrier cell,
- wherein the system information includes one or more, in any arbitrary combination, of:
- control information, or cell-specific implicit and/or explicit control information, for supporting carrier selection,
- the control information comprising one or more, in any arbitrary combination, of:
- received carrier signal strength, or received carrier interference ratio, offset between at least one coverage carrier and at least one capacity carrier,
- offset of at least one carrier-specific downlink synchronization or pilot channel,
- multi-random access channel information indicating that a user is able or allowed to attempt accessing the cell on more than one suitable carrier in parallel.

A method, comprising at least one of
- accessing a multi-carrier cell,
- receiving system information or broadcast information relating to at least one carrier, and
- selecting at least one carrier based on the received information.
A method, comprising:
- providing or broadcasting at least one of a coverage carrier, a capacity carrier, and system information of a multi-carrier cell,
- wherein the system information includes one or more, in any arbitrary combination, of:
- control information, or cell-specific implicit and/or explicit control information, for supporting carrier selection,
- the control information comprising one or more, in any arbitrary combination, of:
- received carrier signal strength, or received carrier interference ratio, offset between at least one coverage carrier and at least one capacity carrier,
- offset of at least one carrier-specific downlink synchronization or pilot channel,
- multi-random access channel information indicating that a user is able or allowed to attempt accessing the cell on more than one suitable carrier in parallel.
