    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.

    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: 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: 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: A method and apparatus for transport format selection in a mobile wireless communication device. During a simultaneous voice and data call, the mobile wireless communication device selects a transport format for proper uplink data transmission. Simultaneous voice and data calls require higher uplink transmit power than voice only calls. The mobile wireless communication device selects a transport format based on the uplink transmit power level. At higher transmit power levels, minimum or zero data rates are chosen to maintain sufficient power for simultaneous voice. Transmit format is specified using a transmit format combination indicator.
