摘要:
Methods and equipments provide mechanisms for delivering out-of-order PDCP PDUs to the PDCP sublayer. In a user equipment configured for dual connectivity between LTE and NR, upon delivering at least one out-of-order PDCP PDU from the RLC sublayer to the PDCP sublayer, a PDCP reordering timer may be initialized. To prevent discarding of LTE PDCP PDUs while the RLC sublayer is performing a retransmission procedure, prior to expiration of the PDCP reordering timer, the out-of-order LTE PDCP PDUs mapped to decoded LTE RLC PDUs may be delivered from the RLC sublayer to the PDCP sublayer without reordering thereof. When the PDCP reordering timer expires, any LTE PDCP PDUs mapped to missing LTE RLC PDUs may be discarded.

Certain aspects of the present disclosure propose techniques that may help improve system performance in a wireless communication network. According to certain aspects, a UE may determine a blocking period, during which traffic volume measurement (TVM) reports are not to be transmitted during a handover (HO) and after completion of the HO, and defer transmission of a TVM report until after the blocking period.

摘要:
Certain aspects of the present disclosure relate to methods and apparatus for wireless communication and more particularly for recovering missing RLC PDUs. In aspects, a method for wireless communications by a user equipment (UE) is provided. The method includes determining whether one or more grant conditions are met, and transmitting a partial status protocol data unit (PDU) and a buffer status report (BSR) based on the one or more grant conditions being met before starting a status prohibit timer if the one or more grant conditions are met. Numerous other aspects are provided.
摘要:
Various aspects of the disclosure relate to techniques for handling out-of-order grants. For example, upon detection of an out-of-order grant, the best scheduling policy for handing the out-of-order grants may be selected based on at least one traffic condition. In some aspects, a scheduling policy may involve canceling and regenerating out-of-order grants. In some aspects, a scheduling policy may involve reordering data units. In some aspects, a scheduling policy may involve designating a reorder time window.
摘要:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may transmit a session initiation protocol (SIP) message. The apparatus may initiate a timer based at least in part on the transmission of the SIP message. The apparatus may trigger, based at least in part on expiration of the timer, at least one of: a radio link failure (RLF) procedure for cell selection, or an out of service (OOS) procedure for radio access technology (RAT) selection.

Embodiments described herein relate to managing communications for a first subscription and a second subscription of a wireless communication device, including, but not limited to, using a reduced re-order release timer having a reduced length in response to determining that a length of a tune-away interval exceeds a threshold. In some embodiments, a reduced status prohibit timer is initiated in response to determining that the length of the tune-away interval exceeds a threshold. In some embodiments, two or more status reports are transmitted during a same status prohibit timer in response to determining that transmission window occupancy exceeds a threshold.
摘要:
A method and apparatus for reducing call drop rate by validating reconfiguration messages based on service data unit (SDU) lifetime are described.A receiving device,such as a user equipment,may determine a receiving delay between receiving a first protocol data unit (PDU) and receiving a last PDU of a reconfiguration message SDU.The receiving delay may be compared with an SDU lifetime.The reconfiguration message SDU may be validated based on the comparison of the receiving delay with the SDU lifetime.A receiving delay that is greater than the SDU lifetime may indicate that the SDU is stale and,therefore,invalid.A receiving delay that is less than the SDU lifetime may indicate that the timing of the SDU is valid and the reconfiguration message SDU is to be processed.An activation time of the reconfiguration message SDU may also be honored or disregarded based on the receiving delay.
摘要:
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE) or component thereof. The apparatus may be configured to transmit to a base station a first request to transmit data in a buffer. The apparatus may be further configured to transmit to the base station a second request to transmit the data in the buffer in absence of a grant in response to the first transmit request. The apparatus may be further configured to remain awake for at least a portion of a scheduled discontinuous reception (DRX) sleep state following the transmission of the second request.
