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： A method is disclosed for coordinating a user equipment's communication with a network during tune back with C-DRX (connected mode discontinuous receive). When a user equipment tunes back to a network after a tune away or a signal fade, a scheduling request is sent to the network to indicate the tune back as quickly as possible. The user equipment waits for a downlink transmission from the network. When the user equipment does not receive the downlink transmission, the method determines if the connection between the user equipment and the network has been released. The sending of the first scheduling request and any additional scheduling requests is coordinated with the C-DRX configuration so as to maximize the battery savings of C-DRX and minimize the latency of the tune back process in case the user equipment has uplink data to send.

摘要翻译： 公开了一种用于在用C-DRX（连接模式不连续接收）回调期间协调用户设备与网络的通信的方法。 当用户设备在离开音乐或信号消隐后调谐回网络时，调度请求将被发送到网络，以尽可能快地指示回调。 用户设备等待来自网络的下行链路传输。 当用户设备没有接收到下行链路传输时，该方法确定用户设备和网络之间的连接是否已被释放。 第一调度请求和任何附加调度请求的发送与C-DRX配置协调，以便最大限度地减少C-DRX的电池节省，并且在用户设备具有发送上行链路数据的情况下最小化回调过程的等待时间 。

摘要： A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.

摘要： Managing radio resources across dual networks includes a wireless mobile device connecting to a first wireless network using a first radio access technology. The wireless device may notify the first network of a capability to be temporarily non-responsive to the first network while maintaining a signaling connection to the first network. The wireless device may communicate with a second network. The wireless device may return to communicating with the first network subsequent to communicating with the second network, and in response to communicating with the second network for less than a predetermined amount of time, the wireless device may send a scheduling request to the first network. In response to receiving a grant acknowledgement from the first network, the wireless device may send a buffer status report that includes a value such as zero to indicate that the wireless device has returned to and can communicate with the first network.

摘要： Electronic devices may have multiple wireless integrated circuits such as first and second baseband processor integrated circuits. The first baseband processors may be used exclusively for handling packet switched traffic, whereas the second baseband processor may be used exclusively for handling circuit switched traffic. Radio-frequency front end circuitry may be used to couple multiple antennas to the baseband processors and associated radio-frequency transceivers. The first baseband processor may be coupled to a first universal integrated circuit card (UICC) storing a first subscriber profile, whereas the second baseband processor may be coupled to a second UICC storing a second subscriber profile. The first baseband processor may be used to support any desired circuit switched radio access technology, whereas the second baseband processor may be used to support any desired packet switched radio access technology.

摘要： Electronic devices may have multiple wireless integrated circuits such as a pair of baseband processor integrated circuits and may have multiple antennas such as a pair of antennas. An electronic device may be operated in different modes depending on the operating environment of the electronic device. When both antennas are unblocked, both baseband processors and both antennas may be used in transmitting signals. When one antenna is not available, the device may be operated in a mode in which the available antenna is used and both baseband processors are used or in a mode in which the available antenna is used and only one of the baseband processors is used. Operating mode decisions may be made so as to minimize the potential for intermodulation distortion and absorbed radiation.
