  • Uplink power headroom reporting for carrier aggregation
    Patent number: 9426752
    Abstract: A method for reporting power headroom is disclosed. Power headroom may be reported across all carriers (wideband), for a specific carrier, or for a carrier group. The formula used to calculate the power headroom depends on whether the carrier (or a carrier in the carrier group) has a valid uplink grant. If the carrier or carrier group does not have a valid uplink grant, the power headroom may be calculated based on a reference grant. The power headroom is calculated by a wireless transmit/receive unit and is reported to an eNodeB.

  • Method and apparatus for using control plane to transmit and receive data
    Patent number: 9398555
    Abstract: Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.
