1. A beamforming method comprising:
- detecting a deterioration of a first communication link between a transmitter and a receiver;
in response to the detecting, obtaining candidate sets of transmission beams and reception beams, wherein at least one of the candidate sets is composed of a respective cluster of beams about a transmission beam or a reception beam on which the first communication link is implemented;
determining a signal quality for each transmission beam and reception beam pair from the candidate sets by transmitting or receiving signals on the respective transmission beam or reception beam in each pair; and
establishing a new communication link with one of the pairs from the candidate sets that is selected based on the determined signal quality for the selected pair.

Abstract
Methods and systems for rectifying deteriorated channel conditions on a communication link are described. In response to the detection of a link deterioration event, a cluster of beams about a currently utilized beam pair can be trialed to determine a suitable, alternate pair of beams on which to establish a communication link. In turn, in the case of a link blockage event, a set of beams having a relatively large azimuthal angle with respect to a currently utilized beam pair can be trialed to determine a suitable beam pair for further communication.

8. A beamforming method comprising:
-
detecting a blockage of a first communication link between a transmitter and a receiver; in response to the detecting, obtaining candidate sets of transmission beams and reception beams, wherein at least one of the candidate sets is composed of respective beams having azimuthal angles that exceed pre-determined thresholds with regard to a transmission beam or a reception beam on which the communication link is implemented; determining a signal quality for each transmission beam and reception beam pair from the candidate sets by transmitting or receiving signals on the respective transmission beam or reception beam in each pair; and establishing a new communication link with one of the pairs from the candidate sets that is selected based on the determined signal quality for the selected pair. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A beamforming system comprising:
-
a transmitter device configured to separately transmit signals on transmission beams in a candidate set of transmission beams; and a receiver device configured to separately apply reception beams from a candidate set of reception beams to receive the signals on the transmission beams and to determine a received signal quality for each transmission beam and reception beam pair from the candidate sets, wherein at least one of the devices is further configured to perform at least one of;
a) detection of a deterioration or a blockage of a first communication link between the devices, and b) determination of at least one of the candidate sets by selecting a respective cluster of beams about a transmission beam or a reception beam on which the first communication link is implemented or by selecting beams for inclusion in the respective candidate set that have azimuthal angles exceeding azimuthal angles of beams in the cluster with respect to the transmission beam or the reception beam on which the first communication link is implemented,wherein the transmitter and receiver devices are further configured to establish a new communication link on one of the pairs from the candidate sets that is selected based on the received signal quality for the selected pair. - View Dependent Claims (16, 17, 18, 19, 20)
