TRANSMISSION OF CONTROL INFORMATION IN A WIRELESS NETWORK WITH CARRIER AGGREGATION
First Claim
1. A method for wireless communication, comprising:
- identifying a first component carrier (CC) and a second CC configured for a user equipment (UE) for carrier aggregation, the first and second CCs being associated with different system configurations, wherein the different system configurations comprise different uplink-downlink configurations; and
receiving an uplink grant sent on the first CC for uplink data transmission on the second CC, wherein the uplink grant is sent on the first CC based on an uplink grant transmission timeline for the second uplink-downlink configuration for the second CC.

Abstract
Techniques for sending control information to support operation on multiple component carriers (CCs) are disclosed. A user equipment (UE) may be configured with multiple CCs for carrier aggregation. The multiple CCs may be associated with different uplink-downlink configurations and may have different downlink subframes and uplink subframes. In one aspect, uplink control information (UCI) for a secondary CC (SCC) may be sent on a primary CC (PCC) based on a UCI transmission timeline for the PCC (and not based on a UCI transmission timeline for the SCC). For example, a downlink grant for the SCC may be sent based on a downlink grant transmission timeline for the PCC. In another aspect, uplink grants for an SCC may be sent on the PCC based on an uplink grant transmission timeline for the PCC (and not based on an uplink grant transmission timeline for the SCC).
