Method and apparatus for transmitting uplink control information for carrier aggregated spectrums

Methods and apparatus for transmitting uplink control information (UCI) in carrier aggregated spectrums are disclosed. UCI may include, but is not limited to, Precoding Matrix Indicator (PMI), Rank Indication (RI), Channel Quality Indicator (CQI), Acknowledge / Not Acknowledge (ACK / NACK) and Scheduling Request (SR). For symmetric carrier aggregation, uplink (UL) and downlink (DL) component carriers may be paired and use physical uplink control channel (PUCCH) in each UL component carrier to send UCI for the corresponding DL component carrier. For asymmetric carrier aggregation, methods are provided for UCI transmission and resource allocation depending on component carrier configuration or assignment. Methods are provided for multiple and single component carrier configurations that may further provide backward compatibility.

Apparatus and method for supporting transmission of sounding reference signals from multiple antennas

Methods and apparatuses, through the use of a Downlink Control Indication (DCI) format or through higher layer signaling, for dynamic activation and deactivation of Sounding Reference Signal (SRS) transmissions from User Equipments (UEs) in an UL Component Carrier (CC) with configured SRS transmissions, the dynamic configuration of SRS transmissions parameters, the dynamic activation and configuration of SRS transmissions in an UL CC without previously configured SRS transmissions for a reference UE, and the configuration of SRS transmissions from multiple UE transmitter antennas.
