    Abstract: PROBLEM TO BE SOLVED: To implement sensor networks using wireless devices.SOLUTION: A wireless device obtains measurements for a first system (e.g., a broadcast system) with which the wireless device is not in communication, and sends the measurements and associated location information and/or timestamps via a second system (e.g., a cellular system). A server receives measurements from a number of wireless devices and determines the coverage of the first system on the basis of the measurements. For other applications, a wireless device obtains sensor information from at least one sensor at the wireless device, and sends the sensor information and associated location information and/or timestamps via a wireless system. A server obtains the sensor information and associated information from a number of wireless devices, aggregates the sensor information, and constructs a map.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for channel estimation in a system employing different transmission protocols such as a broadcast/multicast protocol and a unicast protocol.SOLUTION: When pilots of adjacent slots are used for channel estimation, quality of channel estimation deteriorates significantly. To solve the problem, it is determined whether a first time slot (multicast slot) of one transmission protocol is adjacent to a second time slot (unicast slot) of another transmission protocol (510); a symbol of an edge slot is determined (520); the pilot power and/or the number of pilot sub-carriers is increased (530); and channel estimation is performed using the edge symbol (540).

    Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate serving sector directed transmit power control in a wireless communication environment.SOLUTION: Under certain conditions, an access point can have better data with which to determine appropriate power levels than an individual terminal. Accordingly, an access point can transmit power control information to one or more terminals supported by the access point overriding normal power determination procedures. In particular, power control information can be included within an assignment message that designates resources (e.g., frequency, time) assigned to a terminal. Power control information can be based upon SNR, quality of service requirements, interference information, any other relevant information or any combination thereof.

    Abstract: PROBLEM TO BE SOLVED: To provide a rank step-down method for MIMO SCW (single code word) design employing HARQ.SOLUTION: Systems and methodologies are described that reduce rank (e.g., of a user device) as a number of transmissions therefrom increases. Such rank step-down can improve interference resistance and maintain code rate despite transmission propagation. Additionally, rank step-down information can be encoded along with CQI information to generate a 5-bit CQI signal that can update a user's rank upon each CQI transmission (e.g., approximately every 5 ms). The described systems and/or methods can be employed in a single code word (SCW) wireless communication environment with a hybrid automatic request (HARQ) protocol.

    Abstract: PROBLEM TO BE SOLVED: To provide a technology to support fast frequency hopping using a code division multiplexed pilot in a multi-carrier communication system.
    SOLUTION: Each transmitter transmits a wideband pilot in all sub-bands to make a receiver simultaneously estimate an entire channel response. The wideband pilot for each transmitter can be generated using direct sequence spread spectrum processing and based on a pseudo-random number code assigned to that transmitter. For a time division multiplexed TDM/CDM pilot transmission scheme, each transmitter transmits the wideband pilot in burst. For a continuous CDM pilot transmission scheme, each transmitter continuously transmits the wideband pilot while being at a low transmit power level. Any frequency hopping rate is supported without affecting a pilot overhead.
