| 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 |
| 20100172332 | Method and apparatus for controlling a vocoder mode in a packet switched voice wirelss network - A method for controlling speech vocoder rates in a packet switched voice wireless network, comprises a base station included in the network controlling the adaptive multirate (AMR) codec rate. The network may be in accordance with LTE standards and the base station be an eNB. | 07-08-2010 |

| 20110164574 | Method to improve voice over ip capacity for user equipment employing variable rate vocoders - In one embodiment, a message is sent from the wireless network to a user equipment having a variable rate vocoder. The message defines transport block sizes for the user equipment to select from in making uplink transmissions if the user equipment is permitted to vary a packet size for uplink transmission. A scheduling grant is sent to the user equipment, and the scheduling grant includes an indicator indicating that the user equipment is permitted to vary the packet size for uplink transmissions by selecting a transport block size from among the defined transport block sizes. | 07-07-2011 |

| 20090047962 | Transfer-of uplink power control parameters during handovers - The present invention provides a method for performing handover of a mobile unit from a source base station to a target base station. The source base station determines that a mobile unit should be handed over to the target base station. The target base station transmits uplink power control parameters associated with the target base station to the source base station, which transmits them to the mobile unit. | 02-19-2009 |
| 20090075668 | Method of indicating packet waiting time in wireless packet data systems - The present invention provides a method for indicating packet waiting time in wireless packet data systems. A mobile unit determines a packet waiting time measurement of an amount of time that a data packet has been waiting in a buffer of a mobile unit. The mobile unit then transmits the packet waiting time measurement to a base station. | 03-19-2009 |
| 20090092103 | Method and apparatus for a coordinated scheduling method to avoid multiplexing of control and data for power limited users in the LTE reverse link - A system and method for coordinated scheduling of a telecom device to avoid multiplexing of control signaling and data signaling is disclosed. The method includes defining a round trip time for signaling transmissions. The method further includes allocating the signal transmissions and signal retransmissions for uplink transmissions which are directed by a first scheduling mode and downlink transmissions which are directed by a second scheduling mode to take place in a subframe time position where control signaling transmissions are not being transmitted in subframes where data transmissions and retransmissions are being transmitted. This system and method are particularly useful for telecommunication devices in power limited situations. | 04-09-2009 |
| 20090245207 | System and method to improve uplink coverage in multi-carrier systems - A method of uplink carrier handoff in a multiple carrier communication system may include receiving a measurement report from a mobile providing information regarding path loss as measured at the mobile for one of the multiple carriers on the downlink. 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 |
