The method includes: defining a codebook including at least one precoding matrix composed of a plurality of rows and columns, wherein the codebook is at least one of a first type in which all elements of the precoding matrix are non-zero elements, a second type in which any one column of the precoding matrix includes non-zero element and the remaining columns include at least one zero element, and a third type in which all columns of the precoding matrix include at least one zero element; precoding an input symbol by using the defined codebook; and transmitting the precoded symbol. | 2011-12-22 |
20110310995 | Transcoding multiple media elements for independent wireless delivery - Transcoding multiple media elements for independent wireless delivery. Respective media or multimedia elements are selectively and respectively encoded and/or transcoded. Such respective and selective processing of different media elements provides for their unbundled and independent communication to one or more other devices. In one instance, different respective overlays of a display (e.g., a computer, TV, PDA display, etc.) are respectively and selectively transcoded and/or encoded to generate different respective streams that may each be handled differently as a function of any number of parameters (e.g., media element type, content, communication channel characteristic, source proximity, priority, etc.). Different types of media elements include photo/image, video, graphics, text, audio, picture-in-picture, two-dimensional (2D), three-dimensional (3D), and/or other types of media elements as may be included within a given configuration of a display. Each respective encoding and/or transcoding may be particularly optimized or tailored for a given media element type. | 2011-12-22 |
20110310996 | Spatio-Temporal Processing for Communication - A space-time signal processing system with advantageously reduced complexity. The system may take advantage of multiple transmitter antenna elements and/or multiple receiver antenna elements, or multiple polarizations of a single transmitter antenna element and/or single receiver antenna element. The system is not restricted to wireless contexts and may exploit any channel having multiple inputs or multiple outputs and certain other characteristics. Multi-path effects in a transmission medium cause a multiplicative increase in capacity. | 2011-12-22 |
20110310997 | METHOD OF DISCONTINUOUS RECEIVING STATUS THAT THE USER EQUIPMENT ENTERED - A method for user equipment entering discontinuous reception status, wherein the process of the user equipment side includes: the user equipment starts a timer for entering the discontinuous reception status when the user equipment receives downlink data or uplink grant; the user equipment enters the discontinuous reception status when the timer expires; wherein before the timer expires, if the user equipment receives new downlink data or uplink grant, the user equipment restarts the timer. Further, the process of the base station side includes: the base station starts the timer for the user equipment entering the discontinuous reception status when the base station has sent the downlink data or uplink grant to the user equipment; the base station determines that the user equipment enters the discontinuous reception status when the timer expires; wherein before the timer expires, if the base station transmits again the downlink data or uplink grant to the user equipment, then the base station restarts the timer. | 2011-12-22 |
