Patent number: 8942327Abstract: The present invention employs hierarchical modulation to simultaneously transmit information on different modulation layers using a carrier RF signal. Initially, first data to be transmitted is assigned to a first modulation layer and second data is assigned to a second modulation layer. In one embodiment of the present invention, the first and second data are assigned based on reliability criteria. The first and second modulation layers are hierarchical modulation layers of the carrier RF signal. Once assigned, the first data is transmitted using the first modulation layer of the carrier RF signal and the second data is transmitted using the second modulation layer of the carrier RF signal. In one embodiment of the present invention, information may be transmitted to one end user using one modulation layer, and information may be transmitted to a different end user using a different modulation layer.Type: GrantFiled: October 11, 2012Date of Patent: January 27, 2015Assignee: Apple Inc.Inventors: Ming Jia, Jianglei Ma, Peiying Zhu, Wen Tong, Curt Dodd

Patent number: 8891457Abstract: In a wireless communication system, a base station assigns resources to mobile stations using indices. Each index is associated with an assignment schedule for assigning resources. Once the base station determines an assignment schedule to assign particular resources, it encodes the schedule into an index and transmits it. A mobile station receives the index and decodes it to recover the assignment schedule. Both the base station and the mobile station may use look-up tables and/or algorithms for storing or generating indices associated with assignment schedules. To assign resources so as to indicate transmission characteristics over the resources, the base station transmits assignment blocks. Each assignment block indicates original transmission, retransmission, persistent assignment, non-persistent assignment, HARQ signaling, RAS-HARQ signaling, DRCH assignment, and/or LRCH assignment.Type: GrantFiled: December 8, 2006Date of Patent: November 18, 2014Assignee: Apple Inc.Inventors: Hang Zhang, Mohammadhadi Baligh, Mo-Han Fong, Dongsheng Yu, Sophie Vrzic, Jun Li, Wen Tong, Curt Dodd

SYSTEMS FOR PROCESSING DIFFERENTIATED HIERARCHICAL MODULATION USED IN RADIO FREQUENCY COMMUNICATIONS
Publication number: 20120288038Abstract: The present invention employs hierarchical modulation to simultaneously transmit data over different modulation layers using a carrier RF signal. Each modulation layer may be of a higher or lower order than the other modulation layers. Certain embodiments of the present invention may transmit different information on the different modulation layers. Other embodiments of the present invention may use the different layers for processing information differently.Type: ApplicationFiled: July 18, 2012Publication date: November 15, 2012Inventors: David G.
