User equipment radio frequency and band capability for carrier aggregation measurement gap
Briefly, in accordance with one or more embodiments, user equipment (UE) comprising circuitry to connect to a network via a serving cell; and indicate to the network a measurement gap capability of the UE. The measurement gap capability includes information if the UE supports a carrier aggregation (CA) specific measurement gap and if the UE has two or more radio-frequency (RF) chains. The UE then receives a CA specific measurement gap configuration from the network for the two or more RF chains.
