19 Mar 2010TL;DR: In this article, the authors provide communication services utilizing a combination of non-white spaces (NWS) and white spaces (WS) networks, where the first base station (BS) receives a communication request for network access from a wireless access terminal (AT) and determines at least one available unlicensed frequency corresponding to a location of the wireless AT.
Abstract: The described apparatus and methods provide communication services utilizing a combination of non-white space (NWS) and white space (WS) networks. For example, in an aspect, the described apparatus and methods receive, at a first base station (BS) and on a licensed frequency, a communication request for network access from a wireless access terminal (AT). The aspects also determine at least one available unlicensed frequency corresponding to a location of the wireless AT. Further, the aspects partition at least a portion of the network access for the wireless AT to be via the at least one available unlicensed frequency. Additionally, the aspects inform the wireless AT of the at least one available unlicensed frequency for use to obtain at least the portion of the network access. Additional aspects relate to NWS BS assisted handoffs of WS calls, dynamic caching of WS information, peer-to-peer WS communication, and WS BS venue-specific broadcasting.

21 Mar 2005TL;DR: In this paper, the first and second receive paths for the first wireless system are for two frequency bands and provide receive diversity, while the second receive path for the second wireless system is for a single frequency band and provides receive diversity.
Abstract: A transceiver system includes a first section coupled to a first antenna, a second section coupled to a second antenna, and a radio frequency (RF) unit. The first section includes a transmit path and a first receive path for a first (e.g., GSM) wireless system, a transmit path and a first receive path for a second (e.g., CDMA) wireless system, and a transmit/receive (T/R) switch that couples the signal paths to the first antenna. The second section includes a second receive path for the first wireless system and a second receive path for the second wireless system. The first and second receive paths for the first wireless system are for two frequency bands. The first and second receive paths for the second wireless system are for a single frequency band and provide receive diversity. The transceiver system may include a GPS receive path coupled to a third antenna.

10 Jun 2009TL;DR: In this article, a user may initiate a zoom-in or zoom-out function by tracing an ellipsoidal shape (e.g., a circle) using a user interface device, such as a touchscreen, touchpad or mouse.
Abstract: Methods and devices provide an efficient user interface for providing continuous zoom or magnification of a displayed image on a computing device. A user may initiate a zoom-in or zoom-out function by tracing an ellipsoidal shape (e.g., a circle) using a user interface device, such as a touchscreen, touchpad or mouse. The zoom function continues so long as a touchscreen or touchpad are touched, or a mouse button is depressed, and an ellipsoidal path is traced. Zoom-in or magnification scaling factor may be applied to an image in response to a clockwise path trace and a zoom-out or demagnification scaling factor may be applied to an image in response to a clockwise path trace, or vice versa. A visual aid may be presented on the display that may be followed to conduct the zoom function.

11 Aug 2009TL;DR: In this article, the authors present methods and systems for communications that generate a plurality of spatial streams, wherein each of the spatial streams comprises a data packet with a training sequence, and multiply at least a portion of the training sequence in each spatial stream with a different spreading sequence.
Abstract: Methods and systems for communications that generate a plurality of spatial streams, wherein each of the spatial streams comprises a data packet with a training sequence; and multiply at least a portion of the training sequence in each of the spatial streams with a different spreading sequence. Methods and systems that receive a plurality of spatial streams, wherein each of the spatial streams comprises a data packet with a training sequence; multiply at least a portion of the training sequence in each of the spatial streams with a different spreading sequence; and decode the plurality of spatial streams based on the different spreading sequences.

16 Nov 2005TL;DR: In this paper, a carrier customization module system for a wireless device is described, which is executed by the wireless device which is configured with at least one carrier-specific parameter for a first carrier.
Abstract: A method of customizing a wireless device to a predetermined configuration is described. A wireless device configured with at least one carrier-specific parameter for a first carrier is modified to access at least one carrier-specific parameter for a second carrier during operation of the wireless device and responsive to a predetermined network switch input received by the wireless device. A carrier customization module system for a wireless device includes a carrier customization module loader executed by the wireless device which is configured with at least one carrier-specific parameter for a first carrier. The loader selects at least one carrier-specific parameter for a second carrier from among one or more carrier-specific parameters during operation of the wireless device and responsive to a predetermined network switch input received by the wireless device. The loader modifies the wireless device to access the second carrier using the selected carrier-specific parameter for the second carrier.
