Abstract: Disclosed are techniques for transmitting bundles of silence indicator (SID) frames during a voice call among a plurality of access terminals. In an aspect, a source access terminal detects a transition to a silence state, generates, in response to detection of the transition, at least a first bundle of SID frames, wherein each SID frame of the at least the first bundle of SID frames includes data representing comfort noise to be played at one or more target access terminals of the plurality of access terminals during the silence state, and transmits the at least the first bundle of SID frames to a base station serving the source access terminal. In an aspect, the base station receives the at least the first bundle of SID frames, and periodically forwards SID frames of the at least the first bundle of SID frames to the one or more target access terminals.

Abstract: Techniques for indicating and/or selecting a modulation and coding scheme (MCS) are disclosed. A method for selecting the MCS may comprise receiving control information, identifying a change indicator, determining a first MCS based on the control information, and modifying the first MCS based on the change indicator to determine a second MCS.

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: Methods, systems, and devices for wireless communication are described that provide for scheduling different types of traffic within a data flow, and providing a different coverage enhancement (CE) levels for the different types of traffic. Lower priority traffic within the IP flow may be scheduled with a lower CE level and higher priority traffic within the data flow may be scheduled with a higher CE level. In some cases, the CE levels may be selected to allow for a delay budget that supports real-time communications, such as a voice over LTE (VoLTE) real-time voice communications for bandwidth limited devices or devices that are bandwidth unrestricted but having poor channel conditions.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a first UE. The UE receives an IP packet including header information and data for a MBMS session. The first UE establishes a WWAN communication link with a base station through a WWAN RAT. The first UE provides an access point accessing the WWAN communication link to at least one second UE through a WLAN RAT. The first UE determines a channel condition of the WWAN communication link. The first UE manages at least one multimedia service between the base station and the at least one second UE based on the channel condition.

Abstract: Systems and methods are disclosed for maintaining continuity of a peer-to-peer group session. The method may include exchanging a first P2P group session communication with a member of the P2P group via a direct data traffic connection, requesting session data from an application server, conveying the session data to a proxy UE, wherein the proxy UE is a member of the P2P group, and exchanging a second P2P group session communication with the application server in accordance with the session data.

Abstract: In an embodiment, a first WebRTC proxy module on a first UE receives a multiplexed stream from a first WebRTC multimedia client application on the first UE. The first WebRTC proxy module de-multiplexes into at least first and second de-multiplexed streams. The first WebRTC proxy module sends the first de-multiplexed stream to a second WebRTC proxy module on a second UE via a first set of links with QoS, and sends a second de-multiplexed stream to the second WebRTC proxy module on a second set of links. The second WebRTC proxy module re-multiplexes the first and second de-multiplexed streams to obtain either an original or compressed version of the multiplexed stream, and then delivers the re-multiplexed stream to a second WebRTC multimedia client application on the second UE.

Abstract: The disclosure relates to determining priority access with dual access barring classes. An aspect receives, at a client device, at least one high priority access barring class and at least one low priority access barring class, switches to the low priority access barring class, receives an access barring message, and switches to the high priority access barring class in response to receiving the access barring message. An aspect receives a call request for a high priority call among a group of client devices, transmits a notification to a network instructing it to transmit an access barring message in response to receiving the call request, wherein one or more members of the group of client devices switch to a high priority access class in response to receiving the access barring message, and suppresses call announcements for non-priority call requests after transmitting the notification.
