    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: Methods and apparatus enabling a mobile device to receive paging notifications from multiple networks. In one embodiment of the present invention, a first device connected to a first network momentarily ignores the first network, to monitor a second network instead. The first device identifies and prioritizes a list of applications of the first network; the prioritized listing allows the first device to preempt one of its lower priority tasks to monitor the second network for paging messages instead. The described methods and apparatus enable e.g., GSM paging for Class B cellular devices which are connected to GPRS NMO-2 type networks. The Class B cellular device can ignore certain GPRS data (which is tolerant to error), to decode GSM paging channels, which would otherwise be missed.

    摘要: A method to read selectively system information messages in a mobile wireless communication device. The mobile wireless device receives a first transmission of a multiple segment message through a radio frequency receiver. The mobile wireless device detects decoding errors in at least one of the received segments of the first transmission. In response to detecting decoding errors, the mobile wireless device selectively receives a first subset of segments in a second transmission of the multiple segment message. The mobile wireless device powers down at least a portion of the radio frequency receiver during receive time intervals for a second subset of segments in the second transmission. The first subset of segments in the second transmission corresponds to segments in the first transmission received with decoding errors. The second subset of segments in the second transmission corresponds to segments in the first transmission received without decoding errors.

    摘要: A method of reselecting a mobile wireless communication device to a network subsystem before initiating a connection with a wireless communication network. A connection request is received by the mobile wireless communication device in response to a user input. Attributes of signals received by the mobile wireless communication device from multiple network subsystems in the wireless communication network are measured over a period of time. The mobile wireless communication device is associated with one of the network subsystems and not associated with other network subsystems. The mobile wireless communication device reselects to one of the network subsystems based on quality metrics generated from the measured received signal attributes. After reselection, the mobile wireless communication device initiates a connection through the reselected network subsystem.

    摘要: A method and apparatus for fast cell selection by a mobile wireless device. The mobile wireless device detects when a first wireless cell fails a set of stored suitability criteria and searches for and locates a set of candidate wireless cells to associate with. The mobile wireless device measures at least one received signal metric for each candidate wireless cell in the set of candidate wireless cells. When a candidate cell in the set of candidate wireless cells is identically the first wireless cell, the mobile wireless device evaluates the suitability of the candidate wireless cell using the stored set of suitability criteria for the first wireless cell and the measured at least one received signal metric for the candidate wireless cell. The mobile wireless communication device associates with the candidate wireless cell when the candidate wireless cell meets the stored set of suitability criteria.

The mobile device locates cells in a first of neighbor cells and in a second list of stored cells and evaluates located cells using suitability criteria. When locating a suitable first cell that uses a first radio access technology (RAT) in the first list, the first cell is selected.

    摘要: Transmission capacity for a control channel sent to multiple mobile wireless devices in a wireless network is increased by transmitting the control channel using multi user multiple input multiple output transmissions (MU MIMO). Received signal quality measured at mobile wireless devices in a radio sector are communicated to a radio node and used to determine one or more sets of mobile wireless devices to share transmission of control channel elements on the same time and frequency resource element. The radio node indicates the use of MU MIMO and the selection of precoding matrices to each of the mobile wireless devices in the each set of mobile wireless devices.
