Patent ID: 8825066

Claim:
An apparatus, comprising: at least one processor; and at least one memory storing computer program code; the at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to: reselect, while operating according to a first frequency band mode, to a base station operating according to a second frequency band mode, wherein the first frequency band mode and the second frequency band mode are different frequency band modes having at least one at least partially overlapping frequency channel; receive at least one resource allocation message to allocate from the base station at least one of a downlink channel and an uplink channel of the at least one partially overlapping frequency channel, the resource allocation of said at least one of a downlink channel and an uplink channel complying to at least one of a plurality of radio frequency restrictions of the second frequency band mode and to at least one of a plurality of radio frequency restrictions of the first frequency band mode; and receive information indicating whether the base station, while operating according to the second frequency band mode, can support a user equipment operating according to at least one of a plurality of radio frequency restrictions of the first frequency band mode without the base station operating according to the first frequency band mode, wherein the at least one of a plurality of radio frequency restrictions of the first frequency band mode restricts at least one radio frequency parameter differently than a corresponding radio frequency restriction of the second frequency band mode restricts the radio frequency parameter.
