PROCÉDÉ ET APPAREIL DE COMMANDE AUTOMATIQUE DE GAIN EN PHASE D'APPRENTISSAGE DE FAISCEAU
(ZH)
一种波束训练阶段自动增益控制的方法及装置
Abstract:
(EN)
Disclosed are a method and apparatus for beam training phase automatic gain control. Said beam training phase automatic gain control method comprises: a sending device sequentially using a send beam to send an AGC training sequence to a receiving device, and the receiving device sequentially using a receive beam to receive a corresponding AGC training sequence; the receiving device executing an AGC algorithm after each time the device receives an AGC training sequence, acquiring the AGC gain control value α
i
corresponding to the current send and receive beam combination, where 1≤i≤n; when a supported beam training strategy is beam training based on channel estimation, the receiving device, after acquiring a number n of AGC gain control values α
i
corresponding to send and receive beam combinations, selecting a single α
i
as a uniform optimal AGC gain control value α̂, sequentially receiving a beam training pilot sent by the sending device, and using the uniform optimal AGC gain control value α̂ to perform automatic gain control on each beam training pilot received.
(FR)
L'invention concerne un procédé et un appareil de commande automatique de gain en phase d'apprentissage de faisceau. Ce procédé comprend les étapes suivantes: un dispositif émetteur utilise séquentiellement un faisceau d'émission pour envoyer une séquence d'apprentissage AGC à un dispositif récepteur, et le dispositif récepteur utilise séquentiellement un faisceau de réception pour recevoir une séquence d'apprentissage AGC correspondante; le dispositif récepteur exécute un algorithme AGC chaque fois que le dispositif reçoit une séquence d'apprentissage AGC, acquiert la valeur de commande de gain AGC αi correspondant à la combinaison de faisceaux d'émission et de réception courante, où 1≤i≤n; lorsqu'une stratégie d'apprentissage de faisceau prise en charge est un apprentissage de faisceau basé sur une estimation de canal, le dispositif récepteur, après acquisition d'un nombre n de valeurs de commande de gain AGC αi correspondant à des combinaisons de faisceaux d'émission et de réception, choisit une seule αi comme valeur de commande de gain AGC optimale uniforme α̂, reçoit séquentiellement un pilote d'apprentissage de faisceau envoyé par le dispositif émetteur, et utilise la valeur de commande de gain AGC optimale uniforme α̂ pour effectuer une commande automatique de gain sur chaque pilote d'apprentissage de faisceau reçu.

本文公开了一种波束训练阶段自动增益控制的方法及装置。所述波束训练阶段自动增益控制的方法包括:发送设备依次使用发送波束向接收设备发送AGC训练序列,接收设备依次使用接收波束接收对应的AGC训练序列;接收设备每次接收到AGC训练序列后,执行AGC算法,获取本次收发波束组合对应的AGC增益控制量α
i
,1≤i≤n;在支持的波束训练策略为基于信道估计的波束训练时,接收设备在获取到n对收发波束组合对应的AGC增益控制量α
i
后,从中选取一个α
i
作为统一的最佳AGC增益控制量α̂,依次接收发送设备发送的波束训练导频,使用统一的最佳AGC增益控制量α̂对每次接收的波束训练导频进行自动增益控制。
