  • Earmounted electronic device and method
    Patent number: 7805171
    Abstract: Disclosed is a wireless communication device capable of being positioned in a wearable position adjacent a user's head. The wireless communication device may include a housing and an arcuate earmount coupled to the housing. The earmount may be configured so that it includes an overhanging portion and a hinge portion, the hinge portion electrically and mechanically coupling the earmount to the housing. A proximity sensor can be positioned on the overhanging portion and configured to detect proximity of a user's skin behind the user's ear. The sensor location for earmounted devices can provide that the sensor may be trapped between the user's ear auricle and the user's head as the earmount sits down on the top portion of the ear, which may result in accurate sensing activation. The device may be further configured to, for example, change a state based on whether the proximity sensor detects proximity.

  • Employing different signal thresholds based on type of information transmitted
    Patent number: 7805110
    Abstract: A method is disclosed for determining whether to transmit from a first unit to a second unit, where the transmission is one of a first type and a second type. In the method, a signal from the second unit is received at the first unit, and the strength of the signal as received at the first unit is measured. A determination is made of whether the transmission is of the first type or the second type, and a first threshold is selected if the transmission is of the first type, or else a second threshold is selected if the transmission is of the second type. The measured signal strength is then compared to the selected threshold, and the transmission proceeds only if the measured signal strength exceeds the selected threshold.

  • Method and system for adjusting downlink outer loop power to control target SIR
    Patent number: 7801548
    Abstract: A wireless communication system and method for controlling transmission power to maintain a received signal-to-interference ratio (SIR) as close as possible to a target SIR. A received quality is maintained as close as possible to a target quality based on block error rate (BLER). When a target BLER is converted to an initial target SIR, an error may occur due to a channel condition mismatch, since the target SIR required for the target BLER varies with channel conditions. An outer loop power control process is used to set a target SIR for each coded composite transport channel (CCTrCH) based on the required target BLER. The process adjusts a SIR step size parameter to maximize the convergence speed of the process.

  • Scheduling of uplink data transmission using different UE-IDS
    Patent number: 7801549
    Abstract: A radio terminal adjusts its data transmit power in response to received power control commands which specify a maximum transmit power level. The commands may be addressed to an individual radio terminal by means of a first address, or addressed to a group of radio terminals by means of a second address. In order that the data transmit power of an individual radio terminal is not disrupted by the commands addressed to a group, the radio terminal operates in two states. In the first state the radio terminal responds to commands comprising the first address and does not respond to commands comprising the second address. In the second state the radio terminal responds to commands comprising the second address. The radio terminal transfers from the first state to the second state in response to receiving a command comprising the first address and a predetermined value.

  • Dynamic Adjustment of the pilot-channel, paging-channel, and sync-channel transmission-power levels based on forward-link and reverse-link RF conditions
    Patent number: 7787899
    Abstract: Methods and systems are provided for dynamic adjustment of the pilot-channel, paging-channel, and sync-channel transmission-power levels based on forward-link and reverse-link RF conditions. In an exemplary embodiment, a base station provides service on a carrier in a wireless coverage area, and computes both an Ec/Ior value and a reverse noise rise (RNR) value for the carrier. Based at least in part on the Ec/Ior value and at least in part on the RNR value, the base station adjusts at least one of a pilot-channel power level, a paging-channel power level, and a sync-channel power level for the carrier. As an example, if (a) Ec/Ior is above a first threshold and (b) RNR is below a second threshold, the base station may increase all three of the power levels, so as to improve service quality and coverage, among other advantages.
