    Abstract: PROBLEM TO BE SOLVED: To provide a multi-mode base station that supports a transmission standby mode and an active mode.SOLUTION: In the transmission standby mode at least some of the synchronization signaling such as pilot tone signaling is reduced in power level and/or rate with respect to the active mode. Mode transitions from active to transmission standby may be in response to: a detected period of inactivity, scheduling information, base station mode change signals, and/or detected wireless terminal state transition. Mode transitions from transmission standby to active may be in response to: scheduling information, access signals, wake-up signals from the wireless terminal, hand-off signals, etc.

    Abstract: PROBLEM TO BE SOLVED: To efficiently utilize limited amounts of bandwidth for redundant information communication in improved ARQ mechanisms. SOLUTION: Different NAK signals are used to indicate different relative levels in regard to an unsuccessful attempt to decode a received signal. An ACK signal is used in the case of successful decoding. A device which generates and transmits the original encoded signal receives the NAK signal and selects a portion of redundant information, e.g., additional error correction bits, to be transmitted based on the value of the NAK signal. If the NAK signal indicates a low level decoding success, indicating a relatively large number of errors in the decoded signal, a large set of redundant information is selected and transmitted. If the NAK signal indicates a relatively successful decoding, e.g., relatively few errors, a small set of redundant information is selected and transmitted. When a small set of redundant information is transmitted, new information can be transmitted with the redundant information. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a system that facilitates mitigating effects of asynchronous behavior when transmitting a data signal.SOLUTION: An appropriate time-shifting mechanism is selectively appended to a data signal in order to rectify negative effects of asynchronous time behavior during a logical data burst. The length of a time offset created by the asynchronous behavior is determined. A cyclic prefix is appended to the beginning and/or end of signals. A receiving mobile terminal can employ a signal processing procedure (e.g., FFT) to all portions of a received signal.

    Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for selecting between multiple carriers using a single receiver chain tuned to a single carrier.SOLUTION: A receiver is tuned to a single band, and an estimate value of channel quality corresponding to a currently used carrier and an alternative carrier is generated without switching between carriers. Transmitters of different cells and/or different sectors use different carrier frequencies and periodically transmit using a neighboring sector's carrier frequency. Mobile mode receivers use a single RF chain with a controllable filter to receive and process a signal within a first selected carrier band including a first signal component identified within the first currently selected band and a second signal component identified within a second alternative band. Separate quality indicator values are obtained from the first and second signal components and compared, and a determination is made as to whether the receiver's controllable filter should be switched to the second band.
