  • Patent number: 8559458
    Abstract: 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.

  • Patent number: 7965683
    Abstract: 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.

  • Patent number: 7791717
    Abstract: A system for testing a reflective display device includes a testing apparatus and a computer. The testing apparatus includes one or more light emitters, one or more light detectors, an analog-to-digital converter (ADC) module, and a microcontroller unit (MCU). The light emitters are for projecting light onto a reflective display device located on the testing apparatus. The light detectors are for sensing reflected light from the reflective display device, and generating electricity according to a luminance of the reflected light. The ADC module is for receiving the electrical signals from the light detectors, and producing a digital output according to voltages of the electrical signals. The MCU is configured for reading the digital output of the ADC module. The computer is for processing the digital output and displaying results after processing.
