Abstract: Capacity limited devices may initiate real-time Internet protocol (IP) flows that may include voice data for voice calls. Talk-over patterns may be identified, and an IP flow may be modified based at least in part on the identified talk-over pattern. Such a modification of an IP flow may include, for example, dropping one or more downlink or uplink packets of the IP flow, modifying a semi-persistent scheduling (SPS) grant to suppress one or more uplink transmissions, or modifying a reliability target associated with the IP flow to reduce a number of redundant transmissions or number of retransmissions.

Abstract: Improved methods, systems, devices, or apparatuses support header compression for reduced bandwidth wireless devices prior to an initial transmission that includes a real-time data payload. A data flow containing real-time multimedia data may be initiated between a UE and a base station. In order to enhance the likelihood of meeting data flow timing constraints, compression context may be established prior to a first transmission of a packet with a real-time data payload. The one or more initial transmissions may include a small payload, that is smaller than typical real-time data payloads, may be used to establish compression context for the data flow. When a packet with a real-time payload is to be transmitted, the transmission may use header compression and be transmitted in less time than a transmission without header compression.

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.
