Abstract: A user equipment (UE) operating in a communication system comprising a base station and one or more UEs. The UE may be configured to operate on or “camp” on two different networks with one radio. In this exemplary system, the radio may be normally connected to the first network (NW1) and may from time to time be “tuned away” from NW1 to a second network (NW2). The UE may inform NW1 that it has tuned away to another network, e.g., using start and end indicators. This information may prevent NW1 from wasting downlink capacity by unnecessarily allocating downlink resources to the UE during the tune-away. Alternatively, or in addition, this information may prevent NW1 from penalizing the UE, e.g., by reducing its future downlink allocations, since the UE does not respond to NW1 commands during the tune-away.

Abstract: A method for transitioning a video call is provided. The method can include a wireless communication device participating in a video call with a remote communication device via a first video call session established over a connection between the wireless communication device and a first cellular network. The video call can include a packet switched video stream carried over a first bearer and an audio stream carried over a second bearer. The method can further include the wireless communication device determining a degradation in a connection quality for the first cellular network; transitioning to a legacy cellular network having a circuit switched domain in response to the degradation in connection quality for the first cellular network; establishing a second video call session on the legacy cellular network; and using the second video call session to continue the video call on the legacy cellular network.

Abstract: A user equipment (UE) device may be configured to effectively manage coexistence of multiple radio access technologies (RATs) on the device. Respective controllers responsible for at least partially managing wireless communications according to corresponding respective RATs may communicate to each other expected data transfer patterns that take place over their respective communications links, including application-specific data transfer patterns and data-transfer-mechanism-specific data transfer patterns. The RAT controllers may manage their respective data transfers according to the expected data-transfer pattern information associated with the other RATs received from each in order to prevent data transmission by the device over one RAT link interfering with data transmission of the device over another RAT link. The expected data pattern information may be sent in messaging of a specific type with indexes determined based at least on a status of the data transfer mechanism and a connectivity status of the UE device.

Abstract: Methods and apparatus to mitigate interference among multiple wireless subsystems of a wireless communication device are described. A host processor obtains configurations for a plurality of wireless subsystems and evaluates whether potential or actual coexistence interference exists between two or more of the wireless subsystems. The host processor provides configuration information and link quality reporting parameters to and obtains link quality reports from at least two wireless subsystems. When link quality for at least one wireless subsystem fails a set of link quality conditions, the host processor adjusts data requirements for applications that communicate through one or more of the wireless subsystems and/or adjusts radio frequency operating conditions for one or more of the wireless subsystems to mitigate interference among the wireless subsystems.

Abstract: Outer loop link adaptation for device resumption. A user equipment (UE) and base station (BS) may be in communication in a first network (e.g., an LTE network). Communication between the UE and the BS may be interrupted, e.g., due to a long fading environment, the UE tuning away to a second network (e.g., a CDMA network). Accordingly, the measured error rate may increase dramatically. After resumption from the interruption, a negative offset may be applied to a reported SINR value from the UE due to the previous increase in error rate. Upon improvement in the error rate, a larger, positive offset adjustment may be added to the negative offset, allowing the estimated SINR to return to reported SINR more quickly. Additionally, the error rate estimation may be adjusted to converge to a more recently measured more quickly by decreasing a feedback filter coefficient.

Abstract translation: 用于设备恢复的外环链路自适应。 用户设备（UE）和基站（BS）可以在第一网络（例如，LTE网络）中进行通信。 UE和BS之间的通信可能被中断，例如由于漫长的衰落环境，UE调谐到第二网络（例如，CDMA网络）。 因此，测量的误码率可能会急剧增加。 在从中断恢复之后，由于错误率的先前增加，可能对来自UE的所报告的SINR值应用负偏移。 在改进误差率时，可以将更大的正偏移调整添加到负偏移，从而允许估计的SINR更快地返回到所报告的SINR。 此外，可以通过减小反馈滤波器系数来调整误差率估计以收敛到更近的测量更快。
