摘要： Methods and apparatus are provided for communicating pseudo-orthogonal pilot tones in a multiple antenna communication system. Data is transmitted in a multiple antenna communication system having N transmit antennas by generating a number of pilot tones for each of the N transmit antennas, wherein the pilot tones for each of the N transmit antennas are pseudo-orthogonal with each other; and transmitting the data on each of the N transmit antennas. The pilot tones are generally embedded in the data. Data is received in a multiple antenna communication system having N transmit antennas by receiving the data on each of the N transmit antennas, wherein the data includes a number of pilot tones for each of the N transmit antennas, wherein the pilot tones for each of the N transmit antennas are pseudo-orthogonal with each other. The pilot tones can be orthogonal in the frequency domain, time domain, spatial domain, or all of them.

摘要： Electronic devices may be provided that contain wireless communications circuitry. The wireless communications circuitry may include radio-frequency transceiver circuitry coupled to multiple antennas. An electronic device may alternate between a sleep mode and a wake mode. During wake mode, the electronic device may monitor a paging channel in a wireless network for incoming paging signals. The device may use either a single antenna mode or a multiple antenna mode such as a dual antenna mode in monitoring the paging channel. In the single antenna mode, a single active antenna is used to receive paging signals. In the dual antenna mode two antennas are simultaneously used to receive paging signals. The device may choose which antenna mode to use based on signal quality measurements and history information on successfully received paging signals.

摘要： A single chip mobile wireless device capable of receiving and transmitting over one wireless network at a time maintains registration on two wireless communication networks that each use different communication protocols in parallel. Periodically, the mobile wireless device tunes one or more receivers from a first wireless network to a second wireless network in order to listen for paging messages addressed to the mobile wireless device from the second wireless network. The first wireless network suspends allocation of radio resources to the mobile wireless device based on receipt of a suspension message from the mobile wireless device, or based on knowledge of a paging cycle for mobile wireless device in the second wireless network, or based on detection of an out of synchronization condition with the mobile wireless device.

摘要： A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.
摘要翻译： 用户设备从基站接收分组。 基于给定分组的不完整内容，用户设备可以在分组仍在接收时调用解码。 这种“部分分组解码”依赖于以冗余（代码率小于1）对分组中的底层信息进行编码的事实。 如果链路质量差，则部分分组解码可能不成功，即在尝试恢复基础信息时失败。 为了避免浪费电力，用户设备可以被配置为在对当前分组调用部分分组解码之前应用一个或多个链路质量测试。
