Patent number: 8537763Abstract: A frame (200) and a method for allocating resources that is used in a wireless communication network is provided. The frame includes a first subframe (202) concatenated to a second subframe (204). A first portion (206) of the first subframe allocated for a control channel of a first protocol. A second portion (208) of the first subframe and the second subframe are allocated for a data channel for the first protocol. In an embodiment second portion of the first subframe and the second subframe are allocated for a data channel of the second protocol that are multiplexed with the data channel of the first protocol using frequency division multiplexing (FDM).Type: GrantFiled: June 18, 2009Date of Patent: September 17, 2013Assignee: Motorola Mobility LLCInventors: Fan Wang, Mark C.

Patent number: 8391173Abstract: In an OFDM communication system, wherein a frequency bandwidth is divided into multiple Physical Resource Units (PRUs), a Frequency Partitioning Configuration Module (FPCM) is provided that configures a physical layer for use in multiple coverage areas. The FPCM divides the PRUs into a first group, for frequency selective allocations, and a second group, for frequency diverse allocations. The FPCM subdivides each of the two groups into multiple sets of PRUs, maps the sets of PRUs from the first group to consecutive PRUs allocated for contiguous segment allocation (CS-PRUs), and maps the sets of PRUs from the second group to consecutive PRUs allocated for distributed segment allocation (DS-PRUs). The FPCM permutes the DS-PRUs and allocates the CS-PRUs and the permuted DS-PRUs to at least one frequency partition.Type: GrantFiled: May 10, 2010Date of Patent: March 5, 2013Assignee: Motorola Mobility LLCInventors: Mark C.

Publication number: 20120147813Abstract: During operation, the choice of the initial ranging code (sometimes referred to as a ranging preamble code, or a random-access preamble) at the mobile station is associated with a PMI feedback to be signaled to the base station during the initial ranging. More particularly, during initial system access a ranging code is transmitted by the mobile station to the base station. The mobile station chooses one of the available ranging codes based on the channel conditions and associates the ranging code with channel feedback information. The ranging code is then transmitted to the base station, and provides the base station with the channel feedback information.Type: ApplicationFiled: December 13, 2010Publication date: June 14, 2012Applicant: MOTOROLA, INC.Inventors: Eugene Visotsky, Mark C.

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. Sartori, Kevin L. Baum, Brian K. Classon, Mark C. Cudak

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.

Patent number: 7640373Abstract: A base station (101) will request the transmission of quality information from a particular remote stations (102, 103) only when data is queued to be transmitted to the remote stations. Once a remote station begins the transmission of channel quality information, the transmission of such information continues until the data transmission is successfully delivered to the remote station. The base station receives the channel quality information and adjusts the modulation and coding of the remote stations accordingly. Where data is transmitted simultaneously to a plurality of remote stations, a set of queues (303) for the multiple remote stations is maintained, and based on queue status, a channel quality request messages is sent to a sub-set of remote stations with data queued.Type: GrantFiled: April 25, 2003Date of Patent: December 29, 2009Assignee: Motorola, Inc.Inventors: Mark C.
