Abstract: Methods, systems, and devices are described for wireless communication at a device. A transmitting device such as a base station may select some packets for direct transmission to a receiving device using data compression based on the reliability of the direct connection. The transmitting device may select other packets for indirect transmission via an unreliable connection using uncompressed packets or compressed packets that will not be used to update a compression buffer. In some cases, uncompressed packets may also be sent via the reliable connection. If a packet sent over the unreliable connection is lost, it may be transmitted over the reliable connection.

Abstract: Apparatus and methods of controlling call establishment are described. A user equipment (UE) may determine to establish a call. In an aspect, the UE may detect a Wireless Local Area Network (WLAN) access node and receive, from a Wireless Wide Area Network (WWAN) access node, WWAN load-related information.

In another aspect, the UE may determine WLAN access node characteristics associated with a received signal from a WLAN access node. The UE may forward a call establishment request, including the WLAN access node characteristics to a WWAN access node. The UE may receive a redirection command to redirect the call establishment request to the WLAN access node.

Abstract: The present disclosure presents methods and apparatuses for selective channel reset. For example, the disclosure describes example methods that may include determining that a candidate cell exhibits superior communication properties on a carrier than does a serving cell. In an aspect, this carrier may correspond to an active serving cell channel. The example methods may also include adding a reset flag to a channel reconfiguration message based on the determining, where the reset flag instructs a user equipment to reset a subset of a set of channels associated with the serving cell and the subset includes the channel. Furthermore, example methods may include transmitting the channel reconfiguration message, for example, to a user equipment. Thus, a specified subset of channels associated with the user equipment may be reset, which reduces the signaling load, complexity, and power drain associated with legacy channel reset methods and apparatuses.

Abstract: Aspects relate to a Remote NodeB Relay that appears similar to a NodeB, a Radio Network Controller (RNC), and served mobile devices. Also provided is a Super-Light Router Relay that can provide better performance and QoS to served mobile devices while mitigating modifications to mobile devices, NodeBs, or interfaces between RNC and intermediary NodeBs. Aspects also relate to an Internet Protocol (IP) Relay that requires few, if any, modifications to mobile devices, NodeBs, or interfaces between RNC and intermediary NodeBs. Further, changes to an RNC and/or a core network can be mitigated though utilization of a strategic Relay Gateway.

Abstract: Various apparatuses and methods for transmitting uplink data of an application at a user equipment are provided. In one aspect of the disclosure, uplink data of an application at a user equipment (UE) is transmitted to a network. A first amount of the uplink data expected to be buffered at a radio link control (RLC) layer is determined based on a latency of the application. A second amount of the uplink data available for transmission at the RLC layer is determined based on information provided by a modem of the UE. A data rate of the application is dynamically adjusted based on a difference between the first amount and second amount of the uplink data. In another aspect of the disclosure, an amount of the application data buffered at the RLC layer is maintained to be greater than a predetermined threshold that sets a Happy bit at an unhappy setting. The unhappy setting is communicated to the network, a data rate of the application is increased in response to an increased grant from the network due to the unhappy setting. In another aspect of the disclosure, a maximum modem supported data rate at which the user equipment (UE) transmits uplink data of an application is determined based on an uplink channel capacity estimate, a modem queue length estimate, a codec rate change frequency of the application, and a delay threshold of the modem queue.

Abstract: Aspects of the present disclosure provide an apparatus and method for modem-assisted video telephony. As one example, a user equipment (UE) utilizes a modem to perform video telephony (VT) communication with a remote device through a wireless network. The UE determines a network metric indicative of congestion in the wireless network based on modem information obtained from the modem, independent of feedback information received from the remote device. The UE dynamically adjusts a data rate of the VT communication by an amount proportional to a quantity based on the network metric.

Abstract: Methods and apparatuses are provided for determining available uplink bandwidth as an achievable throughput for a link. An available link capacity of a link with a cell for a user equipment is estimated based on a communication quality measured in the cell. An available fraction of cell resources for the user equipment over the link is also estimated based at least in part on received assistance information. An available bandwidth of the cell is then estimated as an achievable throughput for the user equipment over the link as a function of the estimated available link capacity and the estimated available fraction of cell resources. Moreover, a network procedure can be performed based at least in part on comparing the achievable throughput to one or more thresholds.
