Patent number: 8559458Abstract: A method and scheduler are provided that optimize utilization of an uplink (UL) data packet field of an UL sub-frame. In one embodiment, a request for an allocation of bandwidth is received from each of multiple mobile stations. The requests include requests for a bandwidth allocation of a first size range and requests for a bandwidth allocation of a second size range, wherein each request of the second size range requests more bandwidth than any request of the first size range. Bandwidth is allocated in a UL data packet field to the requests in order of priority, and when the allocated bandwidth does not fill the UL data packet field and a request of the second size range remains unallocated, an allocation of bandwidth to an unallocated request of the second size range is substituted for an allocation of bandwidth to a request of the first size range.Type: GrantFiled: May 27, 2009Date of Patent: October 15, 2013Assignee: Motorola Mobility LLCInventors: David R. Maas, Chen Mu

Patent number: 7965683Abstract: A method and system for allocating a particular uplink control region to both HARQ ACKCH and CQICH in order to maximize uplink bandwidth for data transfer in a communication network. A control region scheduling (CRS) utility assigns a higher priority to HARQ ACKCH relative to CQICH. When both HARQ ACKCH and CQICH are to be allocated for a subscriber in the same region in the same frame, HARQ ACKCH is allocated in the region while CQICH is rejected. As the substitute to the rejected CQICH, the CRS utility may use current uplink channel quality information in combination with the corresponding HARQ ACK transmission to estimate the downlink channel quality information for the subscriber. Upon receiving the HARQ ACK information, the CRS utility updates the subscriber(s) uplink channel quality information. The CRS utility also provides a configurable option of activating or de-activating the sharing of the uplink control region.Type: GrantFiled: June 16, 2008Date of Patent: June 21, 2011Assignee: Motorola Mobility, Inc.Inventors: Chen Mu, Prachi P. Kumar, Nghia T. Vuong, Jun Wang
