摘要： A base station communicates, with a mobile station, data associated with a packet-switched session in which the mobile station is involved. In response to a handover request from the mobile station, the base station accesses information provisioned for the mobile station to determine whether the mobile station is to be subjected to mobility restriction. Based on the accessed information, the base station determines whether to allow handover of the mobile station. A message is sent to the mobile station to indicate that the requested handover is not allowed if the base station determines that the requested handover is not allowed.

摘要： A network comprising a relay node configured to transmit a first common reference signal (CRS) to a plurality of user agents (UAs) using a first plurality of physical antennas and/or virtual antennas, and an access node configured to transmit a second CRS to the UAs using a second plurality of physical antennas and/or virtual antennas, wherein the first CRS and the second CRS are combined for the same number of first and second physical antennas and/or virtual antennas. Included is a network comprising a relay node configured to transmit a dedicated reference signal (DRS) to a UA using a first plurality of physical antennas and/or virtual antennas, and an access node configured to transmit a second DRS to the UA using a second plurality of physical antennas and/or virtual antennas, wherein the first DRS and the second DRS are transmitted at about the same time.

摘要： A method of conveying data through an optical communications system. An optical signal is received through the optical communication system, the optical signal comprising data symbols and SYNC bursts, each SYNC burst having a predetermined symbol sequence. The received optical signal is oversampled to generate a multi-bit sample stream. The sample stream is partitioned into blocks of contiguous samples, wherein each block of samples partially overlaps at least one other block of samples and encompasses at least one SYNC burst and a plurality of data symbols. Each block of samples is independently processed to detect a value of each data symbol.

摘要： A method and system for averaging the effects of polarization distortions across a multitude of transmitted data streams in a dual polarization multiplexed optical communications system. Data streams are interleaved amongst each other in accordance with a predetermined pattern. The interleaved data streams are symbol mapped and modulated to provide a pair of optical signals. The pair of optical signals are orthogonally polarized, and multiplexed for transmission across an optical fibre. A receiver circuit receives the transmitted signal and extracts the interleaved data streams. The interleaved data streams are de-interleaved to generate the original data streams. While the data streams can be interleaved and transmitted via a single wavelength optical signal, the data streams can be interleaved and transmitted over two or more different wavelength optical signals to further mitigate the effects of polarization distortions.
