Patent number: 9252921Abstract: Provided is a method and system for transmitting information. The method includes determining stream length information for at least one data stream to be transmitted and associating the stream length information with a system parameter message. The system parameter message including the associated stream length information is transmitted separately from the data stream. This process facilitates de-multiplexing of individual streams and the processing of stream data even if one or more individual streams are received in error.Type: GrantFiled: May 16, 2011Date of Patent: February 2, 2016Assignee: QUALCOMM IncorporatedInventors: Dhinakar Radhakrishnan, Bruce Collins, Shusheel Gautam

Patent number: 8638714Abstract: A wireless broadcast system is disclosed. The wireless broadcast system includes a transmitter for broadcasting to a wireless communications device. The transmitter receives a plurality of streams on a logical channel, wherein one of the streams contains signaling. The transmitter arranges the streams such that the stream containing the signaling is broadcast after the other streams on the logical channel. The wireless communications device receives the streams broadcast on a logical channel broadcast in a frame, and acquires the logical channel during the broadcast of the frame in response to a prompt received during the broadcast of the same frame.Type: GrantFiled: December 18, 2006Date of Patent: January 28, 2014Assignee: QUALCOMM IncorporatedInventors: Gordon Kent Walker, Bruce Collins, Shusheel Gautam

Patent number: 8194796Abstract: A media access control (MAC) layer controller can manage base layer data and enhancement layer data in a layered modulation system. The MAC layer controller can process both base layer data and enhancement layer data and map the encoded symbols to a layered modulation constellation when both are present. If data for one of the layers terminates, then the MAC layer controller can generate and supply predetermined stuffing data to the layer lacking additional data. The MAC layer controller can send a control signal to the physical layer hardware to cause the hardware to map the layered signals having the stuffing data to a modified signal constellation. The MAC controller can also generate an overhead message that indicates the occurrence of the stuffing data. The receiver can receive the overhead message and can use the information to configure the receiver for the layered modulation constellation or the modified signal constellation.Type: GrantFiled: October 28, 2009Date of Patent: June 5, 2012Assignee: Qualcomm IncorporatedInventors: Bruce Collins, Rajeev Krishnamurthi, Murali Ramaswamy Chair, Shusheel Gautam, Rajiv Vijayan, Seong Taek Chung
