摘要： A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions.

摘要： Techniques for transmitting data in a manner to support multi-user scheduling, multiple-input multiple-output (MIMO) transmission, and interference cancellation are described. A base station assigns multiple time segments of a transmission time interval (TTI) to at least one terminal, maps data for each terminal to at least one time segment assigned to the terminal, and spreads the data in each time segment with at least one channelization code used in the TTI. A terminal receives an assignment of at least one time segment from among multiple time segments of the TTI, obtains input samples for the at least one time segment, and despreads the input samples with the at least one channelization code used in the TTI.

摘要： Creation of update of a security context between user equipment and MSC/VLR (Mobile Switching Centre/Visitor Location Register) for circuit switched domain services is provided. The creation or update is based on conversion of the security context used in an evolved Universal Terrestrial Radio Access Network (E-UTRAN) in the Mobility Management Entity (MME) to a security context for the circuit switched domain target system and transferring it to a MSC/VLR. When user equipment is moved from E-UTRAN to GSM EDGE Radio Access Network/Universal Terrestrial Radio Access Network (GERAN/UTRAN), a MME does not need to perform authentication and key agreement procedures to establish shared circuit switched security context for the user equipment.

摘要： Systems and methodologies are described that facilitate inter-system handover in a wireless communication system. Various aspects described herein provide for handover techniques that enable a target system to be prepared by a mobile device via a source system in order to minimize specific changes required to source system and/or target system. Techniques are described herein in which the radio link of a source system can be utilized to tunnel signaling messages which are in a format understood by a destination node in a target system. Further, fast inter-access handover can be facilitated by establishing a simple generic transmission tunnel between respective network nodes in source and target systems that handle intra-system mobility and providing a Layer 2 (L2) tunneling mechanism over the radio interface of each involved system technology.
