Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Methods and apparatuses to select a transmit antenna in a mobile wireless device connected to a wireless network are described. The mobile wireless device monitors received signal characteristics through first and second antennas and switches antennas based on the monitored signal characteristics and on an assessment of the sufficiency of available transmit power headroom to accommodate data transmissions in the uplink direction. Sufficiency is determined based on one or more criteria including achievable data rate throughput, quality of service, grade of service, an amount of data buffered, an amount of resources allocated by the wireless network and a number of “power up” commands received by the mobile wireless device during a pre-determined time interval.

Abstract: 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.
Abstract translation: 允许移动设备从多个网络接收寻呼通知的方法和装置。 在本发明的一个实施例中，连接到第一网络的第一设备暂时忽略第一网络，以代替监视第二网络。 第一设备识别并优先列出第一网络的应用列表; 优先级列表允许第一设备抢占其低优先级任务之一，而不是替代地监视第二网络的寻呼消息。 所描述的方法和装置能够例如连接到GPRS NMO-2型网络的B类蜂窝设备的GSM寻呼。 B类蜂窝设备可以忽略某些GPRS数据（这是容错误的），以解码GSM寻呼信道，否则会丢失。
