Abstract
According to several embodiments of the present invention, an apparatus (e.g., a UE) monitors a set of component carriers by referring to sub-bands having a sub-band size. The channel quality of the component carriers is detected, best component carriers are identified based on the channel quality, the number of the best component carriers is identified, and the subband size is varied based the identified number of the best component carriers. Identification information and channel quality information on the best component carriers may then be provided, for example to a network control element such as an eNode-B.
Claims46
An apparatus comprising
- a monitor configured to monitor a set of component carriers by referring to sub-bands having a sub-band size,
- a processor configured to detect a channel quality of the component carriers, to identify best component carriers based on the channel quality, to identify the number of the best component carriers, and to vary the sub-band size based the identified number of the best component carriers, and
- a provider configured to provide identification information and channel quality information on the best component carriers.
An apparatus comprising
- a sender configured to send a set of component carriers to be monitored by referring to sub-bands having a sub-band size, and
- a receiver configured to receive identification information and channel quality information on the best component carriers, wherein the sub-band size is variable based on the identified number of the best component carriers.
A method comprising
- monitoring a set of component carriers by referring to sub-bands having a sub-band size,
- detecting a channel quality of the component carriers, identifying best component carriers based on the channel quality, identifying the number of the best component carriers, and varying the sub-band size based the identified number of the best component carriers, and
- providing identification information and channel quality information on the best component carriers.
A method comprising sending a set of component carriers, wherein the component carriers are to be monitored by referring to sub-bands having a sub-band size, and receiving identification information and channel quality information on the best component carriers, wherein the sub-band size is variable based on the identified number of the best component carriers.
