Abstract: A keypad assembly (100) provides improved backlighting in a slim-line from factor with a minimal number of LEDs (130). The keypad assembly (100) utilizes side-firing LEDs (130) mounted to a keypad flex (112) which protrude through subsequent thin layers of substrates.

Abstract: A wireless communication system as described here employs control signaling for contention-based uplink access from user equipment devices to a base station. Contention-based access configuration is performed via physical downlink control channel signaling. Configuration data sent to the user equipment devices identifies multiple contention-based access zones, along with minimum power headroom values for each contention-based access zone. A probability factor may also be used to lower collision possibility by influencing whether the user equipment devices perform contention-based uplink access. An uplink grant message can be used to acknowledge contention-based transmission; contention resolution is achieved implicitly via the uplink grant.

Abstract: A method and device for transmitting data in a wireless communication network uses both cognitive frequency diversity and antenna diversity. The method includes identifying a bandwidth of one or more potentially interfering frequency sub-bands from one or more potentially interfering signals in a radio frequency (RF) band (step 605). Next, based on the bandwidth of the one or more potentially interfering frequency sub-bands, occupancy probabilities are calculated concerning whether the one or more potentially interfering frequency sub-bands will occupy each of a plurality of transmitting sub-bands in the RF band (step 610). Finally, the data are transmitted simultaneously over first and second transmitting sub-bands selected from the plurality of transmitting sub-bands based on the occupancy probabilities, where a first antenna transmits in the first transmitting sub-band and a second antenna transmits in the second transmitting sub-band (step 615).

Abstract: A method for estimating a parameter for low bit rate stereo transmission that includes deriving estimate of any time delay between left and right audio channels in a multi-channel signal from a time delay subsystem. A cross-correlation between the left and right audio channels in the time delay subsystem is employed.

Abstract: Methods and devices are provided for determining location of an input on a surface of a device using an acoustic sensing element. An exemplary method begins by determining an anticipated acoustic response resulting from an output generated by a component of the device at the acoustic sensing element. The method continues by subtracting the anticipated acoustic response from a measured acoustic response at the acoustic sensing element to obtain a nominal acoustic response, and determining the location of the input based on the nominal acoustic response.

Abstract: Embodiments include communication devices and texting methods performed by communication devices. When the communication device detects that a text session has been initiated with a potential real time text (RTT) destination specified as a destination for text messages transmitted by the communication device, the communication device automatically transitions into an RTT transmission mode. While in the RTT transmission mode, text messages may be communicated to the destination using an RTT protocol. A response system may be configured to communicate with the communication device, while the communication device is in the RTT transmission mode.
