Abstract: Various aspects related to control channel (e.g., PSCCH) scheduling/prioritizing techniques in wireless communications are described. When a UE may not be able to decode various PSCCH transmissions detected in a subframe, a subset of the PSCCHs may be selected for decoding based on the described methods. In accordance with one aspect, a UE may determine that a total number of PSCCH transmissions in a subframe is greater than a number of PSCCH transmissions that can be decoded within the subframe. Upon such a determination, the UE may select at least one PSCCH transmission in the subframe for decoding based on at least one of: retransmission information, information regarding a transmitting UE associated with the at least one PSCCH transmission, or scheduling priority history associated with a sub-channel carrying the at least one PSCCH transmission. The UE may then decode the at least one PSCCH transmission selected for decoding.

Abstract: In an aspect, while a mobile device is operating in a RRC_Idle State, an RRC_Suspended State, an RLF State and/or an RLF Recovery Procedure State, the mobile device may transmit a connection establishment message to a base station of a plurality of base stations. In an aspect, the connection establishment message includes information that indicates whether the mobile device has information associated with signals transmitted by one or more base stations of the plurality of base stations. The mobile device may initiate transmission of the information associated with the signals to the base station subsequent to establishing a security context for the connection between the mobile device and the base station. In some aspects, the mobile device may scramble the information associated with signals and transmit the information associated with signals to the base station prior to establishing a security context for a connection between the mobile device and the base station.

Abstract: The disclosure generally relates to network-initiated and client-initiated mechanisms to enable quality of service (QoS) for web-based client applications that may high efficiency, high performance, or otherwise guaranteed service levels. For example, to enable QoS for calls or other sessions associated a web-based application, one or more signaling messages may be exchanged between a server and a first user equipment (UE) to establish a call between the first UE and a second UE and to establish a peer connection between the server and at least the first UE. As such, QoS may be activated for at least the peer connection between the first UE and the server, wherein the server may route data associated with the web-based application between the first UE and the second UE over the established peer connection to implement the activated QoS.

Abstract: In an embodiment, a first MBSFN area is configured to support a higher data rate than a lower data rate portion of a second MBSFN area, and an application server executes a common data rate mode by delivering a data stream for a group session to the first and second MBSFN areas via IP multicast at a common data rate that is regulated by quality feedback. In a further embodiment, the application server exits the common data rate mode and delivers the data stream to the first MBSFN area via IP multicast at an MBSFN-specific data rate that is higher than the common data rate, while delivering the data stream to the lower data rate portion of the second MBSFN area via IP unicast. In another further embodiment, the application server resumes the common data rate mode.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may identify a collision of a first DRX wakeup occasion of a first radio access technology (RAT) and a second DRX wakeup occasion of a second RAT within a discontinuous reception (DRX) interval. The wireless device may identify an offset change for a DRX wakeup occasion of at least one RAT based on the collision. In some cases, the wireless device may transmit a paging offset change request message to a network node, such as a base station or core network node, based on the identified offset change. The wireless device may receive, from the network node, a paging offset acceptance message in response to the paging offset change request message indicating a timing offset for changing the first DRX wakeup occasion or the second DRX wakeup occasion. In some cases, the wireless device may receive an indication from the network node to change a wakeup occasion.
