20090046659 | Message transfer for in-band signaling messages in radio access networks - A method and apparatus for handling in-band signaling messages in radio access networks is provided. The method and apparatus may setup a logical channel, where the logical channel provides packet data control protocol in-band signaling for radio bearers, provide a unique logical channel identifier for the logical channel, receive a packet with a logical channel identifier tag and identify a packet data unit of the packet as a signaling packet data unit. | 02-19-2009 |
20090104916 | Method, apparatus and system for signalling of buffer status information - The present invention is directed to a method, apparatus, system and computer program product for receiving a prioritized bit rate for a radio bearer, and setting a header element based at least on a relation of a measured data rate for the radio bearer and the prioritized bit rate for the radio bearer. A medium access control header element may be set based on the relation between the measured data rate and the prioritized bit rate for the corresponding radio bearer. A network element can derive information on the buffer status of the corresponding bearer, and lower-priority prioritized bit rate bearers. The medium access control header element may be set based on the amount of buffered data for radio bearers not included in the current transport block. The network element can derive information on the buffer status of non-prioritized bit rate bearers of priority lower than the transmitted ones. | 04-23-2009 |
20090125650 | Buffer status reporting apparatus, system, and method - An apparatus, system and method for increasing buffer status reporting efficiency and adapting buffer status reporting according to uplink capacity. User equipment is configured a monitor a usage of a plurality of buffers, detect one of a plurality of pre-selected conditions corresponding to at least one of the plurality of buffers, designate one of a plurality of buffer status reporting formats depending on the pre-selected condition detected, communicate a buffer status report to a network device in accordance with the buffer status reporting format designated. The buffer status reporting format is configured to minimize buffer status reporting overhead created by the communicating of the buffer status report. | 05-14-2009 |
20090141675 | Retransmission Process Control Method - This invention relates to signalling of control information related to retransmissions in a wireless communication network. According to one aspect of the invention, a method for controlling transmission over a wireless communication link is provided. The method comprises the step of indicating on a transmission resource control channel whether a HARQ retransmission process in a mobile station should be activated or deactivated. | 06-04-2009 |
20100035616 | Method, Apparatus and Computer Program Product For Data Forwarding at Handover - An apparatus for facilitating data forwarding at handover may include a processor configured for issuing, from a source node, a handover request to a target node for handing EPC over communications with a mobile terminal from the source node to the target node, receiving acknowledgement of the handover request, and forwarding data to the target node prior to communication of a handover command to the mobile terminal. | 02-11-2010 |
20100202402 | System And Method For Non-Contention Based Handover Based On Pre-Reserved Target Cell Uplink Allocations In Communication Systems - In accordance with aspects of the present invention, a method, apparatus and system for non-contention based handover based on pre-reserved target cell uplink allocations in communication systems. In one embodiment, the apparatus includes a transceiver ( | 08-12-2010 |
20100238799 | Method, Apparatus and Computer Program Product For Handover Failure Recovery - An apparatus for facilitating handover failure recovery may include a handover management element configured to receive, at a target node, a handover request from a source node regarding the handover of communications with a mobile terminal. The handover request may include identity information indicative of the mobile terminal. The identity information may be the identity information used to identify the mobile terminal to the source node during establishment of the original connection between the source node and the mobile terminal. The handover management element may be further configured to receive a request for a connection from the mobile terminal subsequent to a radio link failure and prior to handover completion. Based on matching the identity information from the request for connection and the identity information received from the source node, the target node may establish communication with the mobile terminal based on access stratum configuration information used by the source node. | 09-23-2010 |
20100290427 | APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT PROVIDING SYNCHRONIZED HANDOVER - A method is described which provides a synchronized HO of a mobile device. The method includes receiving a HO command. A determination is made of whether the HO command includes an indication of UL resource allocations. A C-RNTI is waited for in DL signaling if the HO command does not include the indication of UL resource allocations. If the HO command includes the indication of UL resource allocations, transmitting occurs based on the UL resource allocations. The method may be performed as a result of execution of computer program instructions stored in a computer readable memory medium. An apparatus is also described. | 11-18-2010 |
20120207117 | METHOD AND APPARATUS FOR COMMUNICATING SCHEDULING INFORMATION FROM A UE TO A RADIO ACCESS NETWORK - A method by which a UE device and a Node B communicate information such as scheduling information to each other, including a step of sending the information as part of a communication signal instead of padding in the communication signal if the information can be fit by removing all or part of the padding. | 08-16-2012 |
20130142137 | Method and a device for reporting the number of correctly decoded transport blocks in a wireless system - A method and a device for reporting the number of correctly decoded transport blocks in a wireless system. The maximum number of correctly decoded transport blocks within a reporting period is determined. Then the actual number of correctly decoded transport blocks is determined and cultivated into an indication thereof on the basis of the maximum number. The indication is sent to a network element capable of decoding it for analysis. | 06-06-2013 |
