摘要： The present invention relates to the technical field of dynamic spectrum access. Synchronization of quiet periods for spectrum sensing can significantly benefit sharing of available secondary access spectrum between two or more wireless communication systems in the same geographic region. The object of the present invention is to provide a methodology by which quiet periods can be synchronized in time between different secondary access wireless communication systems. Quiet Period Clients (QPC) of secondary access wireless communication systems are adapted to send requests to a Quiet Period Server (QPS) to obtain a quiet period rule set. The QPC receives from the QPS an answer specifying the quiet period rule set, and optional quiet period synchronization information. The systems perform their transmissions in accordance with the received rules.

摘要： A wireless relay node (100) comprises a receiving side (110) and a transmitting side (120) adapted for concurrent reception and transmission of an information stream, and at least one of the two sides has multiple antennas for multi-antenna operation. In the internal design, the wireless relay node is further configured (130) for cancelling signal feedback from a multi-antenna dependent feedback channel from the transmitting side to the receiving side based on an N×M dimensional filter matrix (135) dependent on the multi-antenna dependent feedback channel, where at least one of N and M is greater than 1. In this way, self-interference cancellation of a multi-antenna dependent feedback signal from the output to the input of the wireless relay node is effectively obtained.
