Opportunistic carrier aggregation framework for efficient LTE operation in unlicensed spectrum
First Claim
1. A method operable by a user equipment (UE) configured for operation in a licensed communication band and an unlicensed communication band, comprising:
- establishing a connection with a primary component carrier (PCC);
determining at least one metric associated with a constraint on a transmission channel of a secondary component carrier (SCC) in the unlicensed communication band, the determined at least one metric including a measure of interference from at least one access point;
sending the determined at least one metric on the PCC; and
receiving a message for switching on or switching off the SCC for transmissions on the unlicensed communication band in response to sending the determined at least one metric, wherein the SCC is selected from a set of unlicensed communication bands, the set being associated with a biasing parameter defining a likelihood of selection from the set.

Abstract
Described herein are techniques for reducing efficient LTE operation in the unlicensed band. For example, the technique may involve establishing a connection with a primary component carrier on the licensed communication band or the unlicensed communication band. The technique may also involve determining at least one metric associated with a constraint on a transmissions channel of the unlicensed communication band. The technique may also involve sending the at least one metric to the primary component carrier. The technique may also involve receiving a message for one of switching on or switching off a secondary component carrier (SCC) for transmissions on the unlicensed communication band in response to sending the at least one metric.
