The device can alternatively perform the bandwidth switching and request retransmission of the data portion. Additionally or alternatively, the device can determine a type of the one or more subframes and/or signals transmitted in the one or more subframes to determine whether to perform bandwidth switching in the subframes. The bandwidth switching can include changing a sampling rate, reconfiguring frequency filters, modifying a local oscillator, etc.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus maintains at least one PHR trigger for triggering communication of a PHR for a plurality of component carriers. In addition, the apparatus communicates the PHR for at least one of the component carriers upon the at least one PHR trigger being triggered. The communicated PHR may be an aggregated PHR that includes power headroom information on the PCC and activated SCCs. The communicated PHR may further include an index associating information in the PHR to a corresponding component carrier. The communicated PHR may further include information indicating use of a PUSCH reference for computing the PHR for the at least one of the component carriers on which there is no PUSCH transmission.

Abstract: An access point transmits cell information via a physical layer channel. In some cases, the cell information sent on the physical layer channel comprises a physical layer identifier. For example, a physical layer channel may be modulated based on a cell identifier and/or a closed subscriber group identifier associated with the access point. Through the use of this cell information, an access point may be quickly identified for mobility and/or interference management operations. In addition, this cell information may be used for finger-printing operations.

Abstract: Embodiments of the present disclosure use one or more gain stages to generate an output voltage representing whether a resistive memory element of a data cell stores a high data value or a low data value. In a particular embodiment, an apparatus includes a sensing circuit. The sensing circuit includes a first amplifier stage that is configured to convert a first current through a first resistive memory element of a memory cell into a first single-ended output voltage. A second amplifier stage is configured to amplify the first single-ended output voltage of the first amplifier stage to produce a second single-ended output voltage.

Abstract: Each base station transmits a TDM pilot 1 having multiple instances of a pilot-1 sequence generated with a PN1 sequence and a TDM pilot 2 having at least one instance of a pilot-2 sequence generated with a PN2 sequence. Each base station is assigned a specific PN2 sequence that uniquely identifies that base station. A terminal uses TDM pilot 1 to detect for the presence of a signal and uses TDM pilot 2 to identify base stations and obtain accurate timing. For signal detection, the terminal performs delayed correlation on received samples and determines whether a signal is present. If a signal is detected, the terminal performs direct correlation on the received samples with PN1 sequences for K1 different time offsets and identifies K2 strongest TDM pilot 1 instances. For time synchronization, the terminal performs direct correlation on the received samples with PN2 sequences to detect for TDM pilot 2.

Abstract: Systems and methods are provided for processing wireless signal components for a mobile wireless access broadband service. This can include processes for measuring signal strength of an alternative frequency by tuning away from an existing frequency associated with an existing communications path. Such processes allow determining if the alternative frequency supports a subsequent communications path in a mobile broadband wireless application. Upon the determination, the process can automatically select the subsequent communications path based in part on the measured signal strength.

Abstract: A method and apparatus for selecting a favored transmission slot for communicating non-voice data in conjunction with a voice-data communication. The slot, reflecting a favored power level and transmission rate for transmitting the non-voice data on a supplemental channel, is selected based upon the transmission power levels for voice-data transmitted by a base station to a remote station on a fundamental channel. The favored transmission slot is selected without the remote station messaging information to the base station concerning frequency channel or interference information for the supplemental channel.

Abstract: A novel and improved method and system for paging a cellular telephone or other wireless terminal using two paging channels that reduces standby mode power consumption described. In one embodiment of the invention, a minimally encoded quick paging channel is established over which short, quick page messages are transmitted during one of a set of quick paging slots. The quick page message indicates that a communications request has been received, and that the receiving communication terminals should process a highly encoded full paging channel over which more detailed, full page messages are transmitted during the next full paging slot. A terminal monitors full paging channel only after a quick page message has been received on the quick paging channel.

Abstract: Techniques for reporting channel quality indicators (CQIs) are described. Data activity at a receiver may be determined, and CQI reporting by the receiver may be adjusted based on the determined data activity. In one design, CQI reporting may be enabled for a time window around each expected packet arrival for a periodic or quasi-periodic transmission and may be suspended outside of the time window. In another design, CQI reporting may be varied based on ACK/NACK feedback. In yet another design, CQIs may be sent at a first rate when data activity is not detected and at a second rate faster than the first rate when data activity is detected. In yet another design, CQIs may be sent only during discontinuous transmission (DTX) ON periods when data activity is not detected and may be sent during both DTX ON and OFF periods when data activity is detected.

Abstract: Techniques for supporting periodic and other location services with Secure User Plane Location (SUPL) and other location architectures are described. The techniques can provide position estimates for a SUPL enabled terminal (SET) to a SUPL agent periodically and/or based on trigger events. A Home SUPL Location Platform (H-SLP) receives from the SUPL agent a request for position estimates for the SET. The H-SLP starts a SUPL location session with the SET. For each of at least one reporting event during the location session, the H-SLP obtains a position estimate for the SET and sends the position estimate to the SUPL agent. The position estimate may be derived by the SET and sent to the H-SLP. Alternatively, the position estimate may be derived by the H-SLP based on measurements from the SET.

Abstract: The disclosure describes flicker detection and correction techniques to improve the quality of captured imagery, such as video or still images. In particular, this disclosure describes flicker correction techniques that compare different image frames to detect flicker. In some embodiments, the comparisons involves summing intensity values associated with rows within the frames and comparing the row sums to generate a difference signal. Detection and correction of flicker may be performed using a first derivative of the difference signal. The first derivative of the difference signal can be used in variety of ways to detect and correct flicker.
