摘要： A method of controlling a reset procedure in a wireless communication system sets a proper clocked period to the timer Timer_Status_Prohibit for blocking the timer Timer_Status_Period from interfering with the counting of the state variable VT(RST). In addition, the method of controlling a reset procedure makes use of an amended triggering condition. Therefore, the sender ignores the STATUS PDUs when the reset procedure is ongoing. To sum up, the state variable VT (RST) is not incremented abnormally, and the reset procedure behaves correctly according to the configured protocol parameter MaxRST.

摘要： A radio link control (RLC) layer provides RLC entity information to a medium access control (MAC) layer. The RLC entity information indicates that the RLC layer has service data unit (SDU) data to be transmitted. After providing the RLC entity information, the RLC layer receives an unexpected data interruption that requires the RLC layer to discard or interrupt transmitting the SDU data. After the unexpected data interruption, the MAC layer requests at least a protocol data unit (PDU) from the RLC layer in response to the RLC entity information. The RLC layer then submits to the MAC layer at least one padding PDU in response to the MAC request. The padding PDU is submitted in place of the discarded SDU data. Alternatively, the affected SDU data is not discarded until the next transmission time interval (TTI).

摘要： A transmitter (90) is capable of transmitting protocol data units, PDUs. Each PDU has an n-bit sequence number. A polling determination method is provided that determines if polling should be performed according to a parameter S (98s) that is an n-bit sequence number. Polling is then triggered if a PDU (98p) that is next to be transmitted is not a PDU to be re-transmitted and the polling determination method indicates that polling is to be triggered according to the sequence number (98s) of the PDU. The polling determination method uses the equation:
t = ((2 n + 1 + S - VT(A)) mod2 n )/VT(WS)
to determine if polling should be triggered, where S (98s) is the sequence number of the next outgoing PDU (98p).

摘要： User equipment (UE) can detect a Radio Link Control (RLC) unrecoverable error and a Radio Link (RL) failure. The two errors are handled differently while the UE is in a dedicated channel (DCH) state. The RL failure leads to execution of Radio Access Bearer (RAB) release steps, characterized by utilizing respective timer values to determine if associated RABs should be released. The RLC unrecoverable error is not permitted to execute the RAB release steps. This prevents unnecessary dropping of services. The UTRAN can optionally include and set the indicators to command the UE to perform the indicated RLC re-establishment procedure.

摘要： A method for handling timers in a wireless communication system includes starting a Timer_Poll_Periodic timer for a Radio Link Control Acknowledged Mode (RLC AM) entity, performing a reset procedure for the RLC AM entity, and restarting the Timer_Poll_Periodic timer in response to the Timer_Poll_Periodic timer expiring prior to completion of the reset procedure. The claimed invention also specifies appropriate handling of eight other timers after an RLC reset or re-establishment in order to prevent the RLC AM entity from experiencing deadlock or reduction in quality of service.

摘要： A mobile unit, or UE (User Equipment) includes a Radio Resource Control (RRC) and a plurality of unique states defining the connectivity between the UE and a base station. Once a RRC indicates that it is "Out of Service", a series of timers are started to limit the duration of attempts by the RRC to re-enter an "In Service" condition before the RRC releases allocated resources and moves to an Idle Mode. In certain circumstances, it is necessary to stop one or more of these timers to prevent inadvertently severing the connection.

摘要： When an RRC procedure is combined with an SRNS Relocation procedure, a PDCP synchronization procedure is performed only if a next expected UL/DL Receive PDCP sequence number invalidity event is detected during the SRNS Relocation procedure. If no such invalidity event is detected, then no PDCP sequence number synchronization procedure is performed. If the RRC procedure is not executed in combination with the SRNS Relocation procedure, then the PDCP sequence number synchronization procedure is performed only if: (1) The RRC procedure causes the RLC entity that is used by the PDCP entity to be re-established; or, (2) The RRC procedure causes the header compression protocol used by the PDCP entity to be changed.

摘要： The present invention provides a data discard signaling procedure in a wireless communication system. A Radio Link Control (RLC) provides PDCP in-sequence confirmations. The in-sequence confirmation means that confirmations shall be delivered to PDCP in the same order as PDCP PDUs submitted by PDCP. The sending RLC Acknowledge Mode (AM) entity confirms PDCP Service Data Units (SDUs) with Sequence Numbers (SN) that are positively acknowledged by the peer receiving RLC AM entity. In this way, PDCP PDUs and associated PDCP SDUs with SNs not positively acknowledged will not be deleted by the sending PDCP entity. Another solution provided by the present invention is when the SN for a PDCP SDU carried in a PDCP PDU confirmed by the RLC is larger than the smallest SN for the unconfirmed PDCP SDU, PDCP shall not delete this PDCP PDU and its associated SDU confirmed by RLC until the SN for this PDCP SDU indicated by this confirmation is the smallest or earliest SN. Therefore, the present invention provides a procedure for confirming data transmission which efficiently eliminates problems existing in lossless SRNS Relocation and PDCP Sequence Number synchronization and improves wireless communication system performance.

摘要翻译： 本发明提供一种无线通信系统中的数据丢弃信令过程。 无线电链路控制（RLC）提供PDCP顺序确认。 按顺序确认意味着确认将按PDCP提交的PDCP PDU递送到PDCP。 发送RLC确认模式（AM）实体确认具有由对等接收RLC AM实体肯定确认的序列号（SN）的PDCP业务数据单元（SDU）。 以这种方式，PDCP PDU和没有正确确认的SN的相关联的PDCP SDU将不被发送的PDCP实体删除。 本发明提供的另一解决方案是当由RLC确认的PDCP PDU中承载的PDCP SDU的SN大于未确认的PDCP SDU的最小SN时，PDCP不应删除该PDCP PDU及其由RLC确认的相关SDU 直到该确认指示的该PDCP SDU的SN为最小或最早的SN。 因此，本发明提供了一种用于确认数据传输的方法，其有效地消除了无损SRNS重定位和PDCP序列号同步中存在的问题，并且改善了无线通信系统的性能。
