  • Antenna control system and method
    Patent number: 8155096
    Abstract: Each of multiple directional transmissions from an antenna array of a subscriber unit are received at a base unit. Based on the detected quality of received signals at the base unit, directional transmissions from the antenna array that produce a higher quality of received signal at the base unit receiver are identified. Feedback messages can be used to notify the subscriber unit which of the directional transmissions are optimal. Consequently, settings of an antenna array at the subscriber unit can be adjusted to support more efficient directional transmissions from the subscriber unit to the base unit.

  • Method and apparatus for locating a wireless user
    Patent number: 8155017
    Abstract: A plurality of antennas transmit a first spread spectrum signal having an associated code. The first spread spectrum signal is received at the wireless user. For each received first spread spectrum signal, a second spread spectrum signal is transmitted having an associated code having a same phase as that received first spread spectrum signal. The second spread spectrum signals are received at the plurality of antennas. A distance measurement is determined between each antenna and the wireless user based on in part a received timing of the second signals. The wireless user's location is determined based on in part the distance determinations.

  • Method and system for code reuse and capacity enhancement using null steering
    Patent number: 8149895
    Abstract: The number of users and data capacity of wireless systems are increased by employing apparatus and method for increasing the number of spreading codes available in the system by providing a mechanism to reuse the already allocated spreading code or use the codes that may correlate to those already being used within the same sector/cell. This, in return, provides capacity improvement proportional to the number of added base station (BS) antennas for each cell. An antenna null steering technique for code allocation maintains the cross correlation properties of the codes only for the desired user and to obtain a gain in capacity improvement.

  • Method and system for optimizing power resources in wireless devices
    Patent number: 8144637
    Abstract: A method and system is disclosed for a device to quickly determine if data is being sent to it. If no data is being sent to the device, the device may return to a sleep mode so as to conserve energy. The present invention includes organizing and transmitting, one at a time, all device destination identifiers. If a message listing search indicates that no message is being sent for a device, the device can continue with any other activity that needs servicing, or if no other activity is pending, it may shut down to conserve power until the next wake up period arrives. If the search returns a positive indication, the count value when the identifier is found can be used to determine the location of the pointer to the message.
