摘要： Methods and apparatus for correcting quantization errors in signal reception based on estimated network loading including solutions for preserving cellular network performance in low noise, high interference environments. In one embodiment, a data channel is amplified with respect to other signals based on network load during periods of relatively low network utilization. Dynamic modification of the data channel's power level is configured to overcome quantization errors, rather than the true noise floor (which is insignificant in low noise environments). Such solutions provide both the fidelity necessary to enable high degrees of unwanted signaling rejection, while still preserving data channel quality.

摘要： Maintaining communication of a wireless device and using a plurality of wireless communication technologies. A first paging message schedule may be determined for maintaining communication between the wireless device and a first base station associated with a first wireless communication technology. Similarly, a second paging message schedule may be determined for maintaining communication between the wireless device and a second base station associated with a second wireless technology. Additionally, a scheduling conflict may be determined between the first paging message schedule and the second paging message schedule. Accordingly, communication with the first base station may be switched to a third base station using the first wireless technology in response to determining that there is a scheduling conflict.

摘要： Methods and apparatus enabling a wireless network to implement efficient and robust paging channel operation. In one aspect, the invention permits recovery of a paging channel after a virtual connection failure. A virtually connected UMTS cellular phone that misses a paging notification will no longer be synchronized with its serving radio network, and the resultant loss of synchronization causes a service “blackout” until the devices are resynchronized. Accordingly, in one embodiment, a virtually connected cellular device continuously monitors for fallback messaging, greatly expediting detection and correction of a virtual connection failure. In another embodiment, a virtually connected base station which is unable to page a cellular device in a virtually connected mode continues paging in both virtual connection and fallback modes, thereby provoking an immediate response from the cellular device.

摘要： Methods and apparatus for minimizing scheduling collisions between networks. In one embodiment, the networks are substantially unsynchronized, and during hybrid network operation (e.g., LTE and CDMA 1× operation), a mobile device can place CDMA 1× voice calls while registered with the LTE network. However, since the LTE and CDMA 1× networks are not coordinated, the mobile device will experience scheduling collisions. In one variant, the LTE network accounts for predictable behaviors (such as CDMA 1× paging), and schedules low priority tasks during likely time interval conflicts. Consequently, even though the mobile device must tune away from the LTE network to check CDMA 1× pages, overall LTE network performance is minimally affected.
摘要翻译：用于最小化网络之间的调度冲突的方法和装置。在一个实施例中，网络基本上不同步，并且在混合网络操作（例如，LTE和CDMA 1×操作）期间，移动设备可以在向LTE网络注册的同时放置CDMA 1×语音呼叫。然而，由于LTE和CDMA 1×网络不协调，移动设备将经历调度冲突。在一个变型中，LTE网络考虑到可预测的行为（例如CDMA 1×寻呼），并且在可能的时间间隔冲突期间调度低优先级任务。因此，即使移动设备必须从LTE网络调出来检查CDMA 1×页面，整体LTE网络性能受到最小的影响。

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 be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry with first and second ports that are coupled by switching circuitry to first and second antennas. A first receiver in the transceiver circuitry may be associated with the first port and a second receiver in the transceiver circuitry may be associated with the second port. An electronic device may be operated in a single receiver mode in which only one of the receivers is active to conserve power or a dual receiver mode in which signals from both antennas may be received in parallel to compare antenna performance. Based on antenna performance metrics, the electronic device may adjust the switching circuitry to ensure that an optimal antenna is being used.
