Publication number: 20140140435Abstract: Embodiments of the present invention disclose a transmit diversity method, a related device, and a system, which mainly includes: configuring two different antenna ports separately for different antennas in a network, so that the antennas can use transmit diversity based on the configured antenna ports. In one aspect, because two antenna ports are used in the network to perform transmit diversity, a diversity gain of multiple antennas is obtained. In another aspect, a cavity position caused by a completely identical precoding codebook used in the network is avoided, and therefore network communication performance is improved. The technical solutions according to the embodiments of the present invention efficiently use the transmit diversity of the multiple antennas to acquire diversity gain so as to improve network communication performance.Type: ApplicationFiled: January 27, 2014Publication date: May 22, 2014Applicant: Huawei Technologies Co., Ltd.Inventors: Jiayin ZHANG, Jun NI, Yi WANG

Patent number: 8693363Abstract: Systems (100, 200) and methods for providing TDMA communication. The methods involve determining a channel quality of an uplink channel. A communication delay is set equal to an integer value “K”. “K” is selected based on the channel quality. “K”?“N”. “N” is a total number of frames of a time slot of a TDMA signal (400). Thereafter, First Message Data (FMD) is communicated over the uplink channel in a first time slot (A1) of an uplink signal (1000, 1100, 1200, 1400, 1500, 1600). An Error Control Process (ECP) is performed using FMD to at least identify First Error Free Message Data (FEFMD). Filler data and/or at least a portion of FEFMD is communicated over a downlink channel in a last “N?K” frames of a time slot (A1) of a downlink signal (1050, 1150, 1250, 1450, 1550, 1650), when “K”<“N”.Type: GrantFiled: July 21, 2011Date of Patent: April 8, 2014Assignee: Harris CorporationInventors: Daniel W.

Patent number: 8401543Abstract: An apparatus, system and method are provided for testing a battery-powered electronic device-under-test in a transport frame engaged with a test fixture. A transport frame power supply is arranged to provide power to the DUT in a pre-testing stage. A switching circuit is arranged to switch from the transport frame power supply to a test fixture power supply in response to receiving a power switching signal indicating satisfaction of a pre-testing condition. Power from the test fixture power supply can then be switched back to the first transport frame, or to a second transport frame, to begin testing a second DUT. The ability to start a DUT test without having to wait for the DUT to boot-up in the test fixture reduces test time and increases efficiency of use of test equipment.Type: GrantFiled: January 28, 2010Date of Patent: March 19, 2013Assignee: Research In Motion LimitedInventors: Karoly Goja, Jun Ni, William Mark Dodd, Arkady Ivannikov
