UPLINK CONTROL INFORMATION (UCI) MAPPING INDICATOR FOR LONG TERM EVOLUTION (LTE) CARRIER AGGREGATION
First Claim
1. A method of controlling transmission of Uplink Control Information (UCI) by a User Equipment (UE) configured to be in wireless communication with a processor via a wireless network associated therewith, the method comprising the steps of:
- using the processor, providing radio signaling to the UE; and
using the processor, supplying a UCI mapping bit to the UE via the radio signalingso as to control the UE'"'"'s transmission of the UCI in accordance with a value of the UCI mapping bit.

Abstract
A system and method to instruct a User Equipment (UE) how Uplink Control Information (UCI) on a Physical Uplink Shared Channel (PUSCH) should be transmitted with carrier aggregation. A semi-static signaling of a UCI mapping bit (via a Radio Resource Control (RRC) parameter) is used by a base station such as an eNodeB to require the UE to transmit UCI using one of two pre-determined UCI transmission modes. The bit can be decided by the base station, considering, for example, the available bandwidth or quality of different Uplink Component Carriers (UL CCs) associated with the UE. This network-based solution allows the network to either configure a general rule of UCI transmission by the UE or to enforce the UCI transmission on the Uplink Primary cell (UL Pcell). Because of the rules governing abstracts, this abstract should not be used to construe the claims.
