Abstract: A method to reserve a directional channel, such as in an unlicensed spectrum for instance, is disclosed. In an example embodiment, the method may be performed by a receiving node, such as a user equipment (UE) for instance. In such method, the receiving node may receive an enhanced directional transmit request message from a transmitting node and transmit an enhanced directional transmit confirmation message using one or more first beams, with at least one first beam being directed in a first direction towards the transmitting node. Further, the receiving node may transmit at least one additional enhanced directional transmit confirmation message using one or more second beams, with at least one second beam being directed in a second direction towards a potentially interfering node. In the method, the second direction is a different direction than the first direction.

Abstract: A method that includes interference control at transmitters and interference mitigation at receivers in a wireless communication system is disclosed. Embodiments of the present invention exploit the interference sensitivity at neighboring terminals by taking into account the reciprocity of propagation radio channels in Time Division Duplexing systems (TDD). It can be applied to design the resource allocation for downlink (DL) and uplink (UL) transmissions in a wireless communication system. The methods include the self-configuration of the transmit power, the transmit precoder and the receive filter, at each transmitter and receiver in a multi-cell network. Systems are also provided and configured for implementing the methods of the invention.
