Title (EN) OPERATING A WIRELESS COMMUNICATION SYSTEM
(FR) EXPLOITATION D'UN SYSTÈME DE COMMUNICATION SANS FIL
Abstract:
(EN) OPERATING A WIRELESS COMMUNICATION SYSTEM The present application relates to a method for operating a wireless communi- cation system (10). The communication system (10) comprises a first communi- cation device (20) having an antenna arrangement (22) configured to adjust the polarisation of a radio frequency signal to be transmitted via the antenna ar- rangement (22), and a second communication device (30). According to the method, a first downlink pilot signal (301) having a first polarisation is sent via the antenna arrangement (22) of the first communication device (20). A second downlink pilot signal (302) having a second polarisation is sent via the antenna arrangement (22). The first and second downlink pilot signals are orthogonal to each otherand the first and second polarisations are different. The first and second downlink pilot signals are received at an antenna arrangement (32, 33) of the second communication device (30). A combined power of the first and second received downlink pilot signals (301, 302) isoptimised by varying a combining information. The combined power is a function of the first received downlink pilot signal (301), the second received downlink pilot signal (302), and the combining information. The antenna arrangement (22) of the first communi- cation device (20) is adjusted based on the combining information. (Fig.2)
(FR) La présente invention concerne un procédé d'exploitation d'un système de communication sans fil (10). Le système de communication (10) comprend un premier dispositif de communication (20) comportant un agencement d'antenne (22) configuré pour régler la polarisation d'un signal radiofréquence devant être émis par l'intermédiaire de l'agencement d'antenne (22), et un second dispositif de communication (30). Selon le procédé, un premier signal pilote de liaison descendante (301) ayant une première polarisation est envoyé par l'intermédiaire de l'agencement d'antenne (22) du premier dispositif de communication (20). Un second signal pilote de liaison descendante (302) ayant une seconde polarisation est envoyé par l'intermédiaire de l'agencement d'antenne (22). Les premier et second signaux pilotes de liaison descendante sont orthogonaux l'un à l'autre, et les première et seconde polarisations sont différentes. Les premier et second signaux pilotes de liaison descendante sont reçus au niveau d'un agencement d'antenne (32, 33) du second dispositif de communication (30). Une puissance combinée des premier et second signaux pilotes de liaison descendante reçus (301, 302) est optimisée par variation d'informations de combinaison. La puissance combinée est fonction du premier signal pilote de liaison descendante reçu (301), du second signal pilote de liaison descendante reçu (302) et des informations de combinaison. L'agencement d'antenne (22) du premier dispositif de communication (20) est réglé sur la base des informations de combinaison.
