Patent number: 9271270Abstract: A method in a wireless communication device may include receiving a plurality of sub-frames, each sub-frame having time-frequency resource elements, at least one of the sub-frames having a control channel. In some implementations, the plurality of sub-frames forms a continuum of concatenated sub-frames. Each of the plurality of resource allocation fields of the control channel may indicate a resource assignment to the wireless communication device based on a channel quality report, as well as resource assignments in sub-frames of the continuum of concatenated sub-frames. At least one sub-frame of the continuum of concatenated sub-frames may include information indicating that at least some of the resource assignments are frequency diverse.Type: GrantFiled: February 14, 2013Date of Patent: February 23, 2016Assignee: Google Technology Holdings LLCInventors: Ravi Kuchibhotla, Brian K.

Patent number: 8553594Abstract: A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.Type: GrantFiled: March 20, 2007Date of Patent: October 8, 2013Assignee: Motorola Mobility LLCInventors: Kevin L. Baum, Brian K. Classon, Arvind Krishnamoorthy, Vijay Nangia, Philippe J. Sartori

Patent number: 8018893Abstract: Communications sourced by a remote unit (14) that is already within reception range of a base site (10) can nevertheless be further facilitated through allocation of one or more relay resources (15, 16). Such relay resources, properly employed, then serve to effectively increase the quality of service for the facilitated communication. This, in turn, can permit the use of, for example, increased data rates for communications from a relatively low power remote unit.Type: GrantFiled: May 2, 2005Date of Patent: September 13, 2011Assignee: Motorola Mobility, Inc.Inventors: Philippe J.

Patent number: 7664091Abstract: A method and apparatus for control channel transmission and reception is provided herein. In particular, the use of a partitioned and structured control channel is provided that leverages the benefits of common control while maintaining favorable aspects of dedicated control. During operation, control information is distributed over a number of partitions (201). Each Pi is encoded (607) with monotonically non-increasing reliability level. Control information for a given remote unit can be distributed on one or several partitions, from Pl to Pk, where Pk is encoded with the lowest reliability level that can be decodable by the remote unit at an acceptable error rate.Type: GrantFiled: October 3, 2005Date of Patent: February 16, 2010Assignee: Motorola, Inc.Inventors: Mickael D.
