Abstract: Aspects of the present disclosure provide techniques and apparatus for improving user experience of a voice call associated with a simultaneous voice and long-term evolution (SV-LTE) device (e.g., improving silent redial during a mobile originated (MO) call or mobile terminated (MT) call by a SV-LTE device. A method for wireless communications by a user equipment (UE) capable of communicating via a first packet-based radio access technology (RAT) and a second circuit-switched RAT is provided. The method generally includes detecting initiation of a mobile originated (MO) call, attempting to establish a connection with the first RAT prior to sending a session initiation protocol (SIP) message for the MO call, determining whether the connection is successfully established, and, if the connection is successfully established, sending the SIP message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. A user equipment (UE) may establish a connection to a serving cell and monitor channel conditions for the serving cell and neighboring cells. Based on the channel conditions, the UE may determine to read the system information of a non-serving neighbor. The UE may then read the system information of the non-serving neighbor cell while still connected to the serving cell. In some cases, the UE may store the system information in a database. When the time comes for the UE to access the neighbor cell (e.g., if the link to the serving cell fails) the UE may proceed with access procedures without delay using the stored system information.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus receives an MBMS service from a first cell in a first MBSFN area while in an RRC idle mode. The apparatus reselects to a second cell through an intra-frequency cell reselection upon moving into coverage of the second cell. The second cell is a non-MBSFN cell or an MBSFN cell in a second MBSFN area different than the first MBSFN area. The apparatus continues to receive the MBMS service directly from the first cell while receiving paging signals from the second cell.

Abstract: Methods, systems, and devices are described for media synchronization. Multi-stream media processes may include media streams captured with respect to different clock rates. Multi-processor implementations may involve separate clocks associated with different media streams, such as audio and video, respectively. The separate clocks may tend to drift from one another, becoming further out of sync as time passes. Selecting a reference time of one of the processors to function as a “wall clock,” recording frame capture times with respect to the reference time, accounting for propagation delays, and transmitting frame capture times in terms of the reference time may aid in AV synchronization at a device where audio and video streams are received.
