    Abstract: In order to maintain conformance with exposure limits, in band measurements may be performed. A method, a computer-readable medium, and an apparatus may be provided for wireless communication at a user equipment. The apparatus receives an indication of a cell specific resource, e.g., a cell specific resource available for MPE measurement. The apparatus then performs a measurement based on the cell specific resource and determines whether to adjust a transmission characteristic of the user equipment based on whether the measurement meets a threshold. In another aspect a base station apparatus may configure a cell specific resource in which a user equipment may perform an MPE measurement and control use of the cell specific resource for the MPE measurement.

  • Publication number: 20180167897
    Abstract: Various aspects of the disclosure relate to reporting a power limit along with an indication of at least one constraint upon which the power limit is based. In some aspects, the constraint is a radio frequency (RF) exposure constraint. For example, a power headroom limit calculated by a first apparatus may be constrained by a specific absorption rate (SAR) limit or a maximum permissible exposure (MPE) limit. The first apparatus may thus report to a second apparatus the current power headroom limit of the first apparatus along with an indication of whether the power headroom limit is constrained by an SAR limit or an MPE limit (e.g., as opposed to being constrained by a maximum transmit power limit). The second apparatus may then schedule the first apparatus taking into account the power headroom limit and the corresponding constraint (e.g., maximum power or SAR/MPE).

  • Publication number: 20180160377
    Abstract: Techniques are described for wireless communication at a wireless device, such as a base station, a user equipment, a customer premises equipment (CPE), etc. Some such wireless devices may communicate using beamformed transmissions, which may focus transmission energy in a particular direction. In accordance with the described techniques, a wireless device (e.g., which may or may not use beamforming) may detect an object within an energy mitigation area proximate to the wireless device. The wireless device may determine an allowable energy density at the object based at least in part on the object detection. The wireless device may adjust at least one radio frequency (RF) transmission parameter based at least in part on the allowable energy density at the object.

    Abstract: Methods, systems, and devices are described for selecting a polarization mode. A transmitter may select a polarization mode from a plurality of polarization modes available for transmission. The transmitter may send transmission(s) based on the selected polarization mode.

  • Patent number: 7815119
    Abstract: Contamination in a feedback signal is eliminated in a laser scanning arrangement having a drive coil driven by a drive signal formed as a periodic train of drive pulses to oscillate a scan mirror and a light beam reflected from the scan mirror. A feedback coil generates a feedback signal during oscillation of the scan mirror, the feedback coil being in proximity with the drive coil and being subject to corruption by cross-coupling between the coils. The drive coil is not driven with at least one drive pulse during a quiet time period. Cross-coupling is eliminated by generating the feedback signal only during the quiet time period, and by monitoring a position of the scan mirror by processing the feedback signal which was generated only during the quiet time period.

  • Patent number: 7447252
    Abstract: A radio transmission telemetry system includes several transmitters intermittently transmitting short messages indicative associated sensors status and a receiver for collecting data from the sensors. Each transmitter changes time and frequency of transmissions according to a time-frequency pattern that is different for each transmitter. The receiver identifies each source of transmissions based on its unique variations of the transmission time and frequency, thus eliminating the necessity to include the transmitter ID code in each transmitted message. Thus, overhead in the transmissions is reduced. In addition, the sensor status and other supervisory information such as battery status are partitioned and included in the transmitted messages in portions and at different rates according to the state of the PN-generator for producing the time-frequency pattern. The receiver can determine what and when is included without additional control bits in the transmitted messages.

  • Patent number: 7301986
    Abstract: A radio transmission system including many radio transmitters using frequency hopping carriers to intermittently transmit very short messages indicative of status of stimuli associated with the transmitters. The transmitters transmit transmissions independently of a receiver receiving the transmissions and independent of each other. In operation, radio transmitters transmit messages at varying frequencies at time intervals that can be varied as well. The frequency and time intervals are varied according to patterns that can be determined individually for each transmitter. A receiver holds data indicative of the future transmission frequency and time for each transmitter and updates the data based on the time and the content of the received messages. In addition, a simple method is provided to generate a very large number of orthogonal frequency-time hopping sequences that are individual for each transmitter and based on the transmitter ID.

  • Patent number: 7224713
    Abstract: A telemetry system includes many radio transmitters using frequency hopping carriers to intermittently transmit transmissions indicative of status of sensors associated with the transmitters. The transmitters transmit transmissions independently of a receiver receiving the transmissions and independently of each other. The carrier frequency and the time between transmissions are changed according to a frequency-time hopping sequence that is different for each transmitter. The sequences and the resulting frequency ad time hopping are predictable and can be reproduced in the receiver based on the transmitter ID number. The system also includes one or more receivers containing a plurality of memory registers to hold, simultaneously for each transmitter, digital data indicative of (a) expected time and (b) expected frequency of the next transmission occurrence. The data is updated based on the time and the content of the received transmissions.

  • Patent number: 7209495
    Abstract: A wireless telemetry system includes many radio transmitters using frequency-hopping carriers for intermittently transmitting very short messages indicative of status of stimuli associated with the transmitters. The transmitters can transmit independently of any receiver for receiving from the transmitters and independently of each other. Transmission frequency and time between transmissions are varied according to time-frequency patterns that can be different for each transmitter. Urgent messages, such as alarms, are transmitted at transmission opportunities at intervals smaller than routine transmissions. The transmission opportunities are also according to a time-frequency pattern. Power-up transmissions carry information about future transmission opportunities and/or routine transmissions. Power-up transmissions can also carry information about time-frequency pattern for controlling routine transmissions and/or transmission opportunities.
