摘要:
A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus establishes a wireless connection to a first network, determines a start time of a tune away procedure, enters a transmission freeze state for a first predetermined interval prior to the start time of the tune away procedure, tunes away from the first network for a second predetermined interval, and tunes back to the first network after the second predetermined interval.

Various embodiments for managing uplink transmissions in a mobile communication device may include receiving, on a first subscription of the mobile communication device, an uplink grant from a first network and determining whether a tune-away from the first subscription to a second subscription of the mobile communication device is scheduled to occur during reception of a response message sent from the first network following an initial transmission of a data packet according to the uplink grant. The mobile communication device may use a block error rate and a buffer status report index of a connection between the first subscription and the first network to determine how to manage uplink transmissions following the tune-away.

Various embodiments include methods for adjusting timing advance values on a mobile communication device that includes receiving, on the mobile communication device, a timing advance adjustment value from a base station and determining whether the timing advance adjustment value exceeds an adjustment threshold. The mobile communication device may ignore the timing advance adjustment value in response to determining that the timing advance adjustment value exceeds the adjustment threshold, and may adjust a timing advance value stored on the mobile communication device by the timing advance adjustment value in response to determining that the timing advance adjustment value does not exceed the adjustment threshold.

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus, e.g., UE, suspends a discarding process of data packets associated with a first RAT during tune away by the UE to a second RAT by stopping a discard timer. The UE restarts the discarding process in response to an occurrence of a triggering event. The triggering event may occur when the UE tunes back to the first RAT, or when a duration of the UE tune away to the second RAT exceeds a threshold. The discarding process may be restarted by resuming the discard timer at the point in time where it was stopped or by resetting the timer to zero.

Apparatuses and methods are described herein for a wireless communication device to request uplink grants associated with the first subscription using at least one Radio Frequency (RF) resource, including tuning away from the first subscription to the second subscription for a tune-away time interval, determining whether the tune-away time interval exceeds a threshold, transmitting at least one scheduling request associated with the first subscription for a throttled count in response to the tune-away time interval exceeding the threshold, wherein the throttled count is less than a default count, determining whether an uplink grant has been received in response to any of the at least one scheduling request transmitted within the throttled count, and initiating an uplink data Random Access Channel (RACH) process in response to not receiving the uplink grant.
摘要:
Certain aspects of the present disclosure relate to techniques and apparatus for optimizing long term evolution (LTE) connected discontinuous reception (CDRX) for single radio hybrid tune away devices. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes entering a DRX mode wherein the UE alternates between an activity period and an inactivity period while connected to a first radio access technology (RAT) network, tuning away from the first RAT network for a tune away period to monitor signals in a second RAT network, determining when an inactivity timer for the DRX mode expires or will expire, and adjusting a value of the inactivity timer based, at least in part, on the determination.

Certain aspects of the present disclosure provide techniques and apparatus for quick radio link control (RLC) retransmission on hybrid automatic repeat request (HARQ) failure during tune away. According to certain aspects, a method for wireless communications is provided. The method generally includes performing communications with a base station (BS) using radio components tuned to a first air interface, detecting a tune-away of the radio components from the first air interface to a second air interface while performing the communications, and scheduling one or more packets for retransmission to the BS upon completion of the tune-away, wherein the one or more packets are one or more packets that failed to be transmitted due to the tune-away.
摘要:
Certain aspects of the present disclosure relate to methods and apparatus for a user equipment (UE) to transmit an uplink signal, even though the UE may not have received a negative acknowledgement (NACK) corresponding to the uplink signal from a network due to a tune away period. The method may generally include determining that an acknowledgement/negative acknowledgement (ACK/NACK) signal from a first network corresponding to an uplink signal is scheduled within a tune away period to a second network, and transmitting at least a portion of the uplink signal upon completion of the tune away period based on the determination.
摘要:
Various aspects described herein relate to a user equipment (UE) that can receive a configuration for a radio bearer with an SCell in a radio resource control (RRC) reconfiguration procedure initiated by a primary cell (PCell) serving the UE. A component carrier with the SCell can be activated based at least in part on receiving a control element indicating to activate the component carrier for the radio bearer. It can be determined whether a first deactivation timer, for deactivating the component carrier with the SCell after a period of detected inactivity on the SCell, is configured by the PCell. A second deactivation timer can be configured for deactivating the component carrier with the SCell based at least in part on a determination that the first deactivation timer is not configured by the PCell or that a first configured duration of the first deactivation timer achieves a threshold.
