20090047911 | Method for control channel transmission with persistent scheduling - A method is provided for multiplexing control information with persistently scheduled data in a spectrally efficient operation. In particular, the invention operates to determine and send a power offset parameter in a message carrying a persistent data allocation from a base station to a corresponding mobile station. The power offsets are related to the control information being sent, and specify the amount by which the mobile should increase its transmit power level when multiplexing particular control information together with the persistent data. The increased transmit power then operates to maintain the required QoS on the data channel. | 02-19-2009 |

A serving carrier may be the carrier over which the mobile communicates on the uplink. An instruction may be selectively sent to the mobile to handoff to a non-serving one of the multiple carriers depending on whether a threshold requirement has been met. The meeting of the threshold requirement may be based on the received measurement report and the serving carrier of the mobile. Each of the multiple carriers may have an associated threshold requirement. | 10-01-2009 |
20100260132 | Method For Transmitting Fast Scheduling Request Messages in Scheduled Packet Data Systems - Disclosed is a method of allocating resources in a packet data system to a User Equipment (UE) with an active data session, such as a Voice over Internet Protocol (VoIP) call, using dedicated resources to transmit scheduling requests, thereby reducing latency which may occur as a result of collisions associated with transmitting scheduling requests over a random access channel. The method comprises the step of transmitting over dedicated resources a scheduling request, and receiving a scheduling grant in response thereto. The scheduling request indicates that a transmitter in a data session has a data packet to transmit. The scheduling grant indicates resources allocated for transmitting the data packet. | 10-14-2010 |
