Abstract
(EN)
A resource allocation method and device for amplify-and-forward relay network are provided by the present invention. The method includes: obtaining the channel information, which includes the information of a channel between a Base Station (BS) and a Relay Station (RS) and the information of the channels between the RS and each User Equipment (UE); calculating the resource usage information for each UE on each sub-channel pair based on the channel information; and obtaining the number of the Resource Elements (RE) allocated for each UE on each sub-channel pair based on the resource usage information, wherein the obtained number of the RE maximizes a predefined first function. The embodiments of the present invention improve the resource usage efficiency.
(FR)
L'invention concerne un procédé pour affecter des ressources et un dispositif pour amplifier et transmettre un réseau relais. Le procédé consiste : à obtenir des informations de canal qui comprennent des informations de canal entre une station de base (BS) et une station relais (RS) et des informations de canaux entre la RS et chaque équipement utilisateur (UE) ; à calculer les informations d'utilisation de ressources pour chaque UE sur chaque paire de sous-canaux basées sur les informations de canal ; et obtenir le nombre d'éléments de ressources (RE) affectés à chaque UE sur chaque paire de sous-canaux en fonction des informations d'utilisation de ressources, le nombre de RE obtenu maximisant une première fonction prédéfinie. Les modes de réalisation de l'invention permettent d'améliorer l'efficacité d'utilisation de ressources.
