20150071241 | APPARATUS AND METHOD FOR TRANSMITTING MUTING INFORMATION, AND APPARATUS AND METHOD FOR ACQUIRING CHANNEL STATE USING SAME - The present disclosure relates to an apparatus and a method for transmitting muting information in a wireless communication system, and to an apparatus and a method for acquiring channel state using same. In an exemplary embodiment, muting information includes: a first data field, having a serving cell for receiving from peripheral cells in a multi-cell environment, at least one of a CSI-RS pattern, the number of CSI-RS antenna ports, a CSI-RS duty cycle, and CSI-RS transmission subframe offset information, and using same for expressing the cycle and the offset of muting subframes, which pertain to information on a resource block that can generate interference between the peripheral cells and CSI-RS; and a second data field for expressing a specific muting pattern, which must be muted within the muting subframes, having either 12 bits or 28 bits that display muting application in a bitmap format. | 2015-03-12 |
20150071242 | System and Method for Channel Estimation for Generalized Frequency Division Multiplexing (GFDM) - Embodiments are provided for pre-cancelling signal interference in Generalized Frequency Division Multiplexing (GFDM). Signal interference is pre-cancelled, at a transmitter, so that clean pilots are observed at a receiver and hence used for channel estimation. Using a Pilot-Interference Cancellation (Pilot-IC) method, interference is pre-cancelled at only pilot symbols. Alternatively, interference is simultaneously pre-cancelled at all symbols using a Transmitter IC (Tx-IC) method. The embodiments also include scattering the pilots over frequency and time resources to estimate channels which are frequency selective and time-variant. The channel estimates at the receiver are then used for single-tap channel equalization at time-frequency grid data points, where no assumption of time-invariant channels is required. | 2015-03-12 |
20150071243 | METHOD FOR PERFORMING WIRELESS SWITCHING - A wireless communication system includes an infrastructure device for transmitting and receiving communications to and from a plurality of wireless user terminals. Each wireless user terminal includes a receiver and a controller that receives a plurality of orthogonal frequency division multiplexing (OFDM) signals on a first carrier frequency of a downlink. Each of the plurality of OFDM signals includes carrier frequency assignment information indicating a carrier frequency to transmit uplink data and spatial pattern information indicating a spatial pattern. In response to the carrier frequency assignment information of each of the plurality of OFDM signals, a transmitter and the controller of the wireless user terminal transmit a plurality of uplink signals. Each of the plurality of uplink signals are transmitted on the indicated carrier frequency and using the indicated spatial pattern. | 2015-03-12 |
