摘要： A method and apparatus to improve the robustness of a wireless communication link between a base station and a mobile communication device. The method increases power selectively on portions of an uplink communication signal transmitted from the mobile communication device to the base station. The method monitors a quality metric value at the mobile communication device and sets the transmit power level of the first portion of an uplink communication signal to the first power level, if the monitored quality metric value is in a first range of quality values, or sets the transmit power level of the first portion of the uplink communication signal to a second power level, if the monitored quality metric value is in a second range of quality values. The first portion of the uplink communication signal includes control signals used by a base station to maintain connection of the wireless communication link.

摘要： User equipment such as cellular telephones and other wireless electronic devices may communicate wirelessly with 2G and 3G cells in a cellular network. The cellular network may broadcast a list of primary scrambling codes corresponding to 3G cell sites that are potentially available for wirelessly communicating with the user equipment. The user equipment may perform an evaluation of primary scrambling code pilot signal strengths for each of the primary scrambling codes in the list. The user equipment may also maintain a record whenever a more extensive full primary scrambling code scan fails. If the evaluation reveals that at least one signal strength is sufficient, the cellular telephone may establish a corresponding 3G wireless link. If the evaluation does not identify any sufficiently strong 3G cells, a full pilot signal scan may be performed, provided that no full scans have failed within a predetermined time interval before the current time.
摘要翻译：诸如蜂窝电话和其他无线电子设备的用户设备可以与蜂窝网络中的2G和3G小区进行无线通信。蜂窝网络可以广播与潜在可用于与用户设备无线通信的3G小区站点对应的主扰码的列表。用户设备可以对列表中的每个主扰码执行主扰码导频信号强度的评估。每当更广泛的全主要扰码代码扫描失败时，用户设备也可以保持记录。如果评估显示至少一个信号强度足够，则蜂窝电话可以建立相应的3G无线链路。如果评估没有识别足够强的3G小区，则可以执行全导频信号扫描，只要在当前时间之前的预定时间间隔内没有完全扫描已经失败。

摘要： An electronic device may contain wireless communication circuitry. The wireless communication circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. The electronic device may use the multiple antennas to make received signal power measurements. The signal power measurements may be made for each frequency in a list of frequencies used most recently by the electronic device in conveying data traffic between the electronic device and a wireless network. Based on received signal power measurements, the electronic device may select which frequency to use in performing system acquisition operations to attempt to establish a wireless communications link between the electronic device and the wireless network. The device may make signal power measurements for each antenna in the device to determine which antenna should be used in performing the system acquisition operations or may rotate through antennas in sequence to identify an antenna that can successfully perform system acquisition operations.

摘要： A method to control configuration change times is performed at a mobile wireless communication device when the mobile wireless communication device is connected to a wireless network. The mobile wireless device is connected in a first configuration mode. The mobile wireless communication device receives a control message from a radio network subsystem in the wireless network at a local receive time. The received control message includes a time indication for when to start a configuration mode change of the mobile wireless communication device, which the device extracts from the control message. The mobile wireless communication device reconfigures to a second configuration mode, different from the first configuration mode, based on the extracted time indication and the local receive time.

摘要： Methods and apparatus for modifying network management for hybrid operation. In one embodiment, the networks include an LTE network and a CDMA 1× network, and a mobile device can place CDMA 1× voice calls while registered with the LTE network. However, since the mobile device cannot simultaneously measure information for the LTE network while connected to the CDMA 1× networks, the mobile device modifies measurements and behaviors reported to the LTE network. In one implementation, the mobile device accounts for the time switched away from the LTE network in one or more subsequent reports thereto.
