Abstract: Apparatuses, systems, and methods for high data mode operation in cellular networks. A UE may determine, for an interface to a high-speed cellular network, a categorization from a plurality of categorizations, determine availability of the high-speed cellular network, and select, based at least in part on the categorization and availability of the high-speed cellular network, the interface for a data connection to the high-speed cellular network. The categorization may be one of expensive or not expensive and/or one of a first level associated with a higher compression codec rate or a second level associated with a lower compression codec rate. The UE may receive, from one of the a low-speed cellular network or the high-speed cellular network, carrier plan information for a cellular data service carrier and analyze the carrier plan information to determine desirability of a switch, e.g., from the low-speed cellular network to the high-speed cellular network.

Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. Previously, the instantaneous jitter was derived from a weighted history of the media stream, and consequently only packets that had already been received were used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.

Abstract: Apparatuses, systems, and methods for multi-SIM user equipment (UE) devices to perform emergency calling. A UE may receive an indication to initiate an emergency call. The UE may select a cell on which to initiate the emergency call. If a serving cell of a first SIM of the UE is not available for the emergency call, the UE may utilize information from a second SIM of the UE as part of selecting the cell on which to initiate the emergency call. The information from the second SIM may include an indication of a serving cell of the second SIM. Alternatively or in addition, the information from the second SIM may include an indication of one or more neighboring cells of the second SIM. The emergency call may be initiated via the selected cell using the first SIM.

Abstract: Methods and apparatus for network-based detection and mitigation of hybrid client device reception outage events. For example, in one embodiment, a cellular device uses a single-radio solution to support circuit-switched calls on a CDMA 1X network and packet-switched calls on LTE. Periodically, the cellular device tunes away from LTE and monitors CDMA 1X activity, and vice versa. During these tuned-away periods, the network adjusts operation to mitigate adverse effects (e.g., underutilization of radio resources, synchronization loss, etc.).

Abstract: Methods, apparatuses and computer readable media are described that configure wireless circuitry of a wireless communication device. The wireless communication device establishes a connection to a first wireless network using first and second receiving signaling chains. In response to detecting a radio frequency tune-away event, the wireless communication device reconfigures only one of the radio frequency signaling chains to receive signals from a second wireless network when a set of receive signal conditions for the second wireless network is satisfied. The wireless communication device reconfigures both of the radio frequency signaling chains to the second wireless network when the set of receive signal conditions is not satisfied.

Abstract: A method for reducing power consumption in connected mode discontinuous reception is disclosed. The method can include a wireless communication device sending a transmission for a pending HARQ retransmission process and receiving an ACK for the transmission. The method can further include the wireless communication device determining a subset of remaining uplink transmission opportunities in the pending HARQ retransmission process to monitor for an uplink grant in response to receiving the ACK and monitoring the subset of remaining uplink transmission opportunities for an uplink grant. The method can additionally include the wireless communication device entering a sleep state for any uplink transmission opportunities remaining in the pending HARQ retransmission process after monitoring the subset of remaining uplink transmission opportunities in an instance in which an uplink grant for the pending HARQ retransmission process is not received for any of the subset of remaining uplink transmission opportunities.
