REDUCING BLIND DECODING IN ENHANCED CARRIER AGGREGATION
First Claim
1. A method of wireless communication, comprising:
- receiving a carrier aggregation (CA) configuration comprising one or more first component carriers (CCs) associated with a first control channel restriction and one or more second CCs associated with a second control channel restriction different from the first control channel restriction, wherein the first control channel restriction or the second control channel restriction, or both, comprises a decoding candidate restriction;
monitoring a control channel of the one or more first CCs according to the first control channel restriction; and
monitoring a control channel of the one or more second CCs according to the second control channel restriction.

Abstract
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured with a carrier aggregation (CA) configuration, which may include a large number of component carriers (CCs). Some of the CCs may be designated as basis CCs, and may have a flexible control channel configuration, while other CCs may be designated as supplemental CCs with a restricted control channel configuration. The restricted control channels may have a reduced number of decoding candidates, which may reduce the complexity and increase the likelihood of successfully decoding the control channels. For example, the restricted control channels may be limited to a subset of aggregation levels, a reduced control region, or other restrictions. In some cases, the CCs may be grouped into basis CCs and supplemental CCs based on physical uplink control channel (PUCCH) groups or based on CCs that utilize enhanced physical downlink control channels (ePDCCH).
