摘要： Some embodiments relate to a user equipment (UE) configured to modify at least one signal strength threshold value to provide improved operation for link budget limited devices when performing cell selection or reselection. In some embodiments, the UE may receive a threshold value indicating a minimum received signal strength for camping on a cell. The UE may determine an offset value based on operating parameters of the UE, and may determine a modified threshold value by applying the offset value to the received threshold value. The UE may then compare the modified threshold value to a signal strength measurement of a signal received from a base station associated with the cell. The UE may camp on the cell if the modified threshold value is less than the signal strength measurement, and not camp on the cell if the modified threshold value is greater than the signal strength measurement.

摘要： A wireless communication system is presented for robust mobility management in a HetNet communication system. A source cell can prepare a macro cell and a target small cell as handover candidates during handover decision making and / or preparation. The mobile device is informed about the prepared macro cell and target small cell using radio resource control (RRC) messaging. After receiving a handover command or detecting radio frequency (RF) loss, the mobile device can try to connect with the target small cell. If the mobile device is unable to connect to the target small cell, the UE can fall back and connect to the macro cell.

摘要： 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.
摘要翻译：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。

摘要： Some embodiments relate to an accessory device that may operate in a first mode, where the first radio of the accessory device is configured to perform cellular communication with a base station, or a second mode, where the second radio of the accessory device is configured to perform short-range communication with a companion device and utilize cellular functionality of the companion device to provide cellular communications through the companion device to the base station. The accessory device may operate to selectively transition between the first mode and the second mode based on one or more factors, such as signal strength of the short-range communication between the accessory device and the companion device, the relative batter level of the two devices, and/or a communications status of the companion device.

摘要： Techniques are disclosed relating to informing a network that a UE desires packet-switched voice communication. In one embodiment, a method includes receiving first information from a UE device requesting voice communication over a packet-switched network. In this embodiment, the method further includes transmitting, in response to the first information, second information to a base station serving the UE device, wherein the second information indicates that the UE device is requesting voice communication over the packet-switched network. In this embodiment, the transmitting is performed prior to establishment of a dedicated bearer by the base station for the UE device. In this embodiment, the second information operates to configure communications between the base station and the UE device to provide a particular quality of service for the packet-switched voice communication using the dedicated bearer.
