Abstract: A Node-B sends a polling message to a wireless transmit/receive unit (WTRU). The WTRU sends an uplink synchronization burst in response to the polling message without contention. The Node-B estimates an uplink timing shift based on the synchronization burst and sends an uplink timing adjustment command to the WTRU. The WTRU then adjusts uplink timing based on the uplink timing adjustment command. Alternatively, the Node-B may send a scheduling message for uplink synchronization to the WTRU. The WTRU may send a synchronization burst based on the scheduling message. Alternatively, the WTRU may perform contention-based uplink synchronization after receiving a synchronization request from the Node-B. The WTRU may enter an idle state instead of performing a handover to a new cell when the WTRU moves to the new cell. A discontinuous reception (DRX) interval for the WTRU may be set based on activity of the WTRU.

In response to determining that a valid codeword can be identified, the FEC decoder determines that an alignment of the codeword with the first data window is found. Otherwise, the FEC decoder selects a second data window of the predetermined size and attempts to decode the second data window.

Abstract: Methods (100) and apparatuses (12, 24, 38) taught herein advantageously facilitate use of timing measurements in wireless communication networks (10) where radio signal timing measurements involve signals at different carrier frequencies. The methods and apparatuses in particular compensate such timing measurements for expected discrepancies in the measurements that arise from frequency-dependent differences in the propagation behavior of the radio signals being measured. In a non-limiting example, measurements at two or more frequencies may be compensated for the frequency distance between those frequencies, or with respect to a reference frequency. In such cases, timing measurements determined for one or more other radio signals are compensated as a function of the frequency distance between the reference frequency and the frequencies of such other radio signals.

The system receives an FEC-coded Ethernet frame that includes the even delimiter, which is a predetermined sequence that separates a conventional Ethernet frame and FEC parity bits in the FEC-coded Ethernet frame.

Both the first and second Hamming distances are shorter than a predefined value. The system subsequently selects one of the first and second sets of frame bits having the shorter Hamming distance as the even delimiter.

Abstract: Low latency and computationally efficient techniques may be employed to account for errors in data such as low bit-width, oversampled data. In some aspects these techniques may be employed to mitigate audio artifacts associated with sigma-delta modulated audio data. In some aspects an error may be detected in a set of encoded data based on an outcome of a channel decoding process. Upon determining that a set of data may contain at least one error, the set of data may be replaced with another set of data that is based on one or more neighboring data sets. For example, in some aspects a set of data including at least one bit in error may be replaced with data that is generated by applying a cross-fading operation to neighboring data sets. In some aspects a given data bit may be flipped as a result of a linear prediction operation that is applied to PCM equivalent data that is associated with the given data bit and its neighboring data bits.
