  • Publication number: 20240147572
    Abstract: 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.

  • Patent number: 11856451
    Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving control signaling that configures the UE with a retransmission request time duration for requesting packet retransmission relative to when a packet in a sequence of packets is determined to be unsuccessfully received, monitoring for one or more transmissions including at least a subset of packets in the sequence of packets, and transmitting, prior to expiration of the retransmission request time duration, a first retransmission request to request retransmission of at least one packet in the sequence of packets based on a first retransmission trigger being satisfied.

  • Patent number: 11387945
    Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive a set of packets having a sequential order. The UE may initiate a first packet data convergence protocol (PDCP) reordering timer based on a first time stamp corresponding to unsuccessful decoding of a first packet in the sequential order. The UE may then initiate, prior to the expiration of the first PDCP reordering timer, a second PDCP reordering timer. The second PDCP reordering timer may be based on a second time stamp corresponding to unsuccessful decoding of a second packet in the sequential order. In some cases, the UE may initiate the second PDCP reordering timer after expiration of the first PDCP reordering timer, but may decrease the duration of the second PDCP reordering timer.

  • Patent number: 11357037
    Abstract: 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 handling 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.

  • Publication number: 20220070659
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may monitor packet data convergence protocol (PDCP) counter values associated with PDCP packets. The UE may control a PDCP mode of the UE based at least in part on the monitoring of the PDCP counter values. Numerous other aspects are provided.

  • Publication number: 20190124575
    Abstract: 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.

  • Publication number: 20170078177
    Abstract: 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.

  • Publication number: 20160135114
    Abstract: Aspects described herein relate to throttling packet-switched (PS) call establishment in wireless communications. A circuit-switched (CS) call can be conducted by using a first radio access technology (RAT). A cell update (CU) procedure for a PS call using a second RAT can be detected as due to one or more conditions. A cause for the one or more conditions can be determined based on one or more parameters related to a transmitter or receiver.
