Patent application number | Description | Published |
20080198869 | Enhanced polling method for preventing deadlock in a wireless communications system - A method of polling in a wireless communications system includes prohibiting polling within a predetermined period and triggering a poll function while polling is prohibited. After the predetermined period has expired the method determines that there are no protocol data units (PDUs) scheduled for transmission or re-transmission and that the poll function was triggered by a “Last PDU in Retransmission buffer” trigger, and selects a PDU to schedule for re-transmission to fulfill the poll function. | 08-21-2008 |
20080205371 | Enhanced polling method for preventing deadlock in a wireless communications system - A method of polling in a wireless communications system includes prohibiting polling within a predetermined period and triggering a poll function while polling is prohibited. After the predetermined period has expired the method determines that there are no protocol data units (PDUs) scheduled for transmission or re-transmission and that the poll function was triggered by a “Every Poll_PDU PDU” trigger, and selects a PDU to schedule for re-transmission to fulfill the poll function. | 08-28-2008 |
20080205372 | Enhanced polling method for preventing deadlock in a wireless communications system - A method of polling in a wireless communications system includes prohibiting polling within a predetermined period and triggering a poll function while polling is prohibited. After the predetermined period has expired the method determines that there are no protocol data units (PDUs) scheduled for transmission or re-transmission and that the poll function was triggered by a “Every Poll_SDU SDU” trigger, and selects a PDU to schedule for re-transmission to fulfill the poll function. | 08-28-2008 |
20080212605 | Enhanced polling method for preventing deadlock in a wireless communications system - A method of polling in a wireless communications system includes prohibiting polling within a predetermined period and triggering a poll function while polling is prohibited. After the predetermined period has expired the method determines that there are no protocol data units (PDUs) scheduled for transmission or re-transmission and that the poll function was triggered by a “window-based” trigger, and selects a PDU to schedule for re-transmission to fulfill the poll function. | 09-04-2008 |
20080273551 | Method and Related Apparatus for Handling Packet Discard in a Wireless Communications System - A method for handling packet discard in a transmitter of a wireless communications system includes activating a “use of a special value of a header extension field” mode, discarding a plurality of service data units, wherein the last service data unit of the plurality of service data units ends at an end of a first protocol data unit using the special value in a header extension field, and setting a value of a field to be a sequence number of a second protocol data unit, wherein the field is utilized for indicating a receiver to discard all not yet successfully received service data units that have segments with sequence number being less than the value of the field, and the second protocol data unit is next to the first protocol data unit. | 11-06-2008 |
20080279218 | Abnormal case handling for acknowledged mode transmission and unacknowledged mode transmission - Whenever the Receiver of this invention receives an AMD PDU or a UMD PDU with its “Length Indicator” having an invalid or a reserved value, the Receiver discards such a PDU and treats it as never received. The Receiver may report its receiving status accordingly if a report is required. This invention avoids invoking unnecessary RLC reset procedures and reduces the chance of losing HFN synchronization during AM or UM data transmissions. | 11-13-2008 |
20080285583 | Method and Apparatus for Polling Transmission Status in a Wireless Communications System - A method for polling transmission status in a transmitter of a wireless communications system includes forming a status protocol data unit including a poll sequence number field indicating a sequence number of a protocol data unit to be polled when a polling procedure is triggered to poll a receiver, setting a value of the poll sequence number field to be a sequence number of a next protocol data unit to be transmitted for the first time minus 1, and transmitting the status protocol data unit to the receiver. | 11-20-2008 |
20090046608 | Method and Apparatus for Setting Headers in a Wireless Communications System - A method for setting headers in a transmitter of a wireless communications system includes dividing a Radio Link Control Protocol Data Unit into a plurality of segments each including a header, and setting the header to include a field indicating a sequence number of the Radio Link Control Protocol Data Unit. | 02-19-2009 |
20090046695 | Method and Apparatus for Triggering a Poll Function in a Wireless Communications System - A method for triggering a poll function in a transmitter of a wireless communications system includes triggering the poll function for polling status of a receiver, and a radio link control entity of the transmitter supporting a “Last PDU” trigger and a “Poll retransmission timer” trigger, and not supporting a “Periodic Timer” trigger. | 02-19-2009 |
20110028171 | Method and Apparatus for Optimizing Radio Resource Control Procedures in Wireless Communication System - A method for optimizing a radio resource control procedure in a wireless communication system is disclosed. The wireless communication system supports Coordinated multi-point (CoMP) transmission/reception, which enables a plurality of cells cooperating and providing services for a user equipment (UE). The method includes defining cells directly or indirectly participating in transmission to the UE within the plurality of cells as members of a CoMP cooperating set, and setting the cells of the CoMP cooperating set to use a same system frame number. | 02-03-2011 |
