Abstract: A method for managing uplink communication in wireless communication network is provided. The method includes selecting one or more Mobile Stations (MSs) from a plurality of MSs based on a first signal parameter corresponding to each MS of the one or more MSs, one or more second signal parameters corresponding to each MS of the one or more MSs, and one or more threshold parameters. The first signal parameter is associated with a Base Station (BS) serving a MS. Further, the one or more second signal parameters are associated with one or more BSs neighboring to the MS. The one or more threshold parameters are associated with a communication parameter. Thereafter, the method includes modifying uplink Modulation and Coding Scheme (MCS) level of the one or more MSs.

Abstract: Systems and methods are provided for efficient tree-based detection of multi-carrier modulated signals, such as Orthogonal Frequency Division Multiplexing (OFDM) symbols. In an embodiment, a plurality of signals occupying respective tones are received and processed to determine an order, based on a tone quality metric, for the plurality of signals. The plurality of signals are then dispatched to a pool of tree detectors in accordance with the order. In an embodiment, the order ensures that signals occupying higher quality tones, and requiring shorter detection times, are dispatched first to the pool of tree detectors. In another embodiment, a maximum runtime of busy tree detectors of the pool is updated based signal on actual detection times to exploit the time slack of early terminating detectors.

Abstract: An interference suppression (IS) time/frequency zone for improved interference suppression is provided. The IS time/frequency zone can be scheduled and set up using existing signaling of the Almost Blank Subframe (ABS) framework. This includes using the existing signaling of the ABS framework to schedule the IS time/frequency zone, coordinate transmission parameters among base stations for the IS time/frequency zone, and signal the IS time/frequency zone to the UT. In another aspect, interfering base stations align respective reference signals during the IS time/frequency zone, which allows the UT to measure the channels from its serving base station and/or the interfering base stations(s). With channel state information knowledge at the UT, interference suppression can be achieved.

Abstract: A method and system are provided in which a device comprising a first or main phase locked loop (PLL) and a second or reference PLL, is operable to communicate utilizing a first and a second receiving antenna. The first PLL may generate a first signal based on a reference signal generated by the second PLL. A second signal may also be generated based on the reference signal. Data associated with a first radio access technology (RAT) may be received via the first receiving antenna utilizing the generated first signal. The first RAT or another RAT may be scanned via the second receiving antenna utilizing the generated second signal. The scan via the second receiving antenna may be performed concurrently with the reception of data via the first receiving antenna. A switch may be utilized to enable or disable scanning operations via the second receiving antenna.
