Iterative beam selection method with receiver and transmitter diversity
First Claim
1. A method for determining at least one beam of a transmitter and at least one beam of one or more receivers with a specific signal transmission quality between the transmitter and the respective receiver,wherein the transmitter and each receiver comprise a plurality of predetermined transmitter and receiver beams, respectively,said method comprising a radiation pattern determination routine with the steps oftransmitting a transmitter training burst for each receiver from the transmitter to the respective receiver, consecutively, wherein the plurality of predetermined transmitter beams of the transmitter is applied during each transmitter training burst in a sequence;
- transmitting at least one feedback burst to the transmitter, wherein the feedback burst comprises information based on each transmitter training burst received by the respective receiver, wherein said information identifies at least one transmitter beam of the plurality of predetermined transmitter beams of the transmitter with a specific signal transmission quality for each receiver, wherein a number of the identified at least one transmitter beam is smaller than a number of the plurality of predetermined transmitter beams;
transmitting a receiver training burst for each receiver from the transmitter to the respective receiver, consecutively, wherein the respective transmitter beam with a specific signal transmission quality of the identified at least one transmitter beam of the transmitter for the respective receiver is applied during each receiver training burst;
receiving the receiver training burst by the respective receiver, wherein the plurality of predetermined receiver beams of the respective receiver is applied during each receiver training burst in a sequence;
identifying at least one receiver beam of the plurality of predetermined receiver beams of the respective receiver with a specific signal transmission quality, wherein a number of the identified at least one receiver beam is smaller than a number of the plurality of predetermined receiver beams; and
repeating the radiation pattern determination routine at least once,wherein the identified at least one transmitter beam and the identified at least one receiver beam of the preceding radiation pattern determination routine are used as a new assortment of the plurality of predetermined transmitter and receiver beams of the succeeding radiation pattern determination routine for the transmitter and the respective receiver.

Abstract
The present invention relates to a method for determining the best transmitter and receiver beams with a reduced number of calculations for the best antenna beam arrangement between a transmitter and a receiver. The iterative routine within this method comprises a transmitter beam determination sequence, a feedback sequence and a receiver beam determination sequence. While calculating the best possible antenna beam arrangement, the antenna beam width does not require to be reduced.
