    Abstract: PROBLEM TO BE SOLVED: To provide techniques for dynamically mapping assigned resources to physical resources.SOLUTION: A resource assigned for communication may be mapped to a first physical resource on the basis of a first mapping function and to a second physical resource on the basis of a second mapping function. The assigned resource may be configurable for hopping or no hopping. The first mapping function may be a transparent function or may map consecutive input indices to non-consecutive output indices. The second mapping function may be equal to an output of the first mapping function plus an offset defined by a step size and a hop value. The hop value may be configurable for the assigned resource and may be conveyed in a resource assignment. The hop value may be set to a first value to indicate no hopping or to a second value to indicate hopping by the step size.

    Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and method for efficiently estimating the signal-to-noise ratio of a received signal irrespective of intentional adjustment to transmission power by varying the data rate.SOLUTION: Variation in power due to variation in the data rate is decoupled from environmental sources for variation in power. In one embodiment, the signal-to-noise ratio is adjusted for the data rate. In another embodiment, another signal is used as a reference for the signal-to-noise computation. This advantageously permits a system to efficiently and accurately control power in a power control loop for efficient use of spectral bandwidth and for relatively good grade of service.

    Abstract: PROBLEM TO BE SOLVED: To support multiple wireless access technologies at a common terrestrial radio access network.SOLUTION: Wireless resources can be reserved in a manner that enables transmission of control and reference signals to advanced or emerging-technology user terminals (e.g., LTE-A), while mitigating adverse effects on legacy user terminals (e.g., LTE Release 8). Therefore, information designated for LTE-A terminals can be embedded in predetermined reserved locations, which exploit known standardized behavior of legacy terminals in expecting information at specific locations. Such a reservation of resources can be made typically without affecting the legacy terminals, and thus performance degradation of legacy terminals can be mitigated or avoided.

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate defining new control channels in legacy wireless networks.SOLUTION: Control data resources for new systems are defined in the legacy wireless network specification. Legacy devices are still supported after new control data resources are implemented. The new control data resources are reserved over the general data resources to avoid the interference over legacy control and reference signal resources (S802). In addition, new system devices create a substantially non-interfered global control segment not including data communication resources over new control resources (S804). Control data are transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like (S806).

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate selecting frequency for transmitting a control channel format indicator (CCFI) so as to identify a related cell.SOLUTION: CCFI data is transmitted in an initial portion of frequency (such as an orthogonal frequency division multiplexing (OFDM) symbol) in a time transmit interval (TTI). The CCFI data is spread across the initial portion of frequency and shifted to identify a transmitting cell. Additionally, the CCFI data is scrambled to further identify the cell. The CCFI data is also utilized to determine structure of subsequent control and/or data channels.

    Abstract: PROBLEM TO BE SOLVED: To provide techniques for performing scrambling and descrambling.SOLUTION: Different scrambling sequences for different channels are generated based on different cyclic shifts of a base scrambling sequence generated by a linear feedback shift register, which is a maximal-length sequence. A scrambling sequence for a given channel is generated by (1) determining a sequence selector value based on at least one parameter for a channel type value and (2) cyclically shifting the base scrambling sequence based on the sequence selector value. In addition, a reference signal transferred on variable system bandwidth is generated with two scrambling sequences, which are different cyclic shifts of a base scrambling sequence. Scrambling/descrambling for positive and negative frequencies for the reference signal is performed with the first and second scrambling sequences, respectively.
