Abstract:
Methods, devices and computer programs for determining new transmit directions to use for beamformed transmissions in case the link quality of an existing direction falters. A transmitting communication device and a receiving communication device cooperate via a beam tracking procedure to determine a new suitable transmit direction to use for upcoming beamformed transmissions. Information relating to the beam tracking procedure is communicated over an existing link that enables communication between the transmitting and receiving communication devices. The receiving communication device provides the transmitting communication device with information about a beam scan performed in order to detect tracking beams transmitted by the transmitting communication device. This information allows the transmitting communication device to determine suitable transmit directions to use.

Claim (Index 1):
A method performed by a transmitting communication unit for determining beam directions suitable to use for communication between the transmitting communication unit and a receiving communication unit, the transmitting communication unit and the receiving communication unit being connected through an existing radio link, wherein the method comprises:\n triggering, by means of a message transmitted over the existing radio link, the receiving communication unit to perform a beam scan; transmitting, according to a pre-determined transmission scheme, tracking beams in different transmit directions, to enable the receiving communication unit perform the beam scan for each transmit direction in order to detect a transmitted tracking beam; receiving information about the outcome of the performed beam scan from the receiving communication unit over the existing radio link, said information enables the transmitting communication unit to identify at least one transmit direction that led to a detection of a tracking beam during the performed beam scan; and determining, based on the received information, a suitable transmit direction to use for beamformed transmissions to the receiving communication unit, wherein the transmitting the tracking beams is performed based on a pre-determined transmission scheme that comprises information about time intervals during which the tracking beams are transmitted over particular transmit directions, and transmitting information of the pre-determined transmission scheme to the receiving communication unit over the existing radio link.
