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.

Wireless communication methods, systems, and computer program products

A method, wireless device and computer program product for expanding the coverage of a cellular network. A wireless device (e.g., cellular telephone) is able to communicate with a base station in a cell of the cellular network over a non-cellular interface via another wireless device in the cell through the use of multi-hopping. A wireless device may request permission to communicate with the base station over a non-cellular interface via hopping off another wireless device when its signal strength is below a threshold. Alternatively, a wireless device may receive a request to communicate with the base station over a non-cellular interface via hopping off the wireless device that sent the request when that wireless device has excess capacity in its bandwidth with the base station. By enabling wireless devices to communicate with a base station in such a manner, the effective coverage area of the cellular network is expanded and the effective capacity of the cellular network is improved.

Method and System for Determining the Position of a Mobile Station

A method of determining the location of a mobile device is provided. The method receives a signal with a known radio transmission pattern at the mobile device from each of several transmitting devices. The method correlates each received signal with a corresponding signal that has a same known radio transmission pattern to determine the time the signal traveled between the corresponding transmitting device and the mobile device. The method determines the location of the mobile device based on the time the signal travelled between the corresponding transmitting device and the mobile device. In some embodiments, determining the location of the mobile device does not require calculating a distance between the mobile device and any of the transmitting devices. In some embodiments determining the location of the mobile device includes solving a function that is dependent on the time the signals traveled between each corresponding transmitting device and the mobile device.
