  • Publication number: 20120155644
    Abstract: A method for communicating end-to-end encrypted super group information is provided. Temporary address data, which identifies a temporary address on which the super group is to communicate, is transmitted from a gateway to a back-to-back communications device using a direct mode or data message. The back-to-back communications device retrieves an encryption key associated with the temporary address and uses the encryption key to decrypt super group information sent from a networked communications device on the temporary address. The back-to-back communications reverts back to its original encryption key when super group communications are terminated.

  • Publication number: 20120147813
    Abstract: During operation, the choice of the initial ranging code (sometimes referred to as a ranging preamble code, or a random-access preamble) at the mobile station is associated with a PMI feedback to be signaled to the base station during the initial ranging. More particularly, during initial system access a ranging code is transmitted by the mobile station to the base station. The mobile station chooses one of the available ranging codes based on the channel conditions and associates the ranging code with channel feedback information. The ranging code is then transmitted to the base station, and provides the base station with the channel feedback information.

  • Publication number: 20120139810
    Abstract: An antenna system includes a multi-port antenna with an active feeding network coupled thereto. The active feeding network applies complex weights to signals received from and transmitted to each port of the multi-port antenna. The complex weights are applied according to eigenvectors corresponding to a Hermitian matrix representation of the multi-port antenna. The Hermitian matrix may be base on such multi-port antenna parameters such as power dissipation, power radiation, real-power flow, volumetric storage of electromagnetic energy, and/or volumetric dissipation of electromagnetic energy. The multi-port antenna yields orthogonal electromagnetic fields in volumes or surfaces of interest in response to the active feeding network excitation.
