Abstract
(EN)
Some embodiments of the present disclosure provide a contention window size (CWS) adjustment method and a network device for transmission in an unlicensed spectrum. The method comprises: receiving a plurality of HARQ responses, wherein a downlink channel corresponding to the plurality of HARQ responses occupies one or more basic bandwidths in a reference time unit; determining the number of HARQ responses in one basic bandwidth; and adjusting, on the basis of the ratio of NACKs in said one basic bandwidth, a CWS corresponding to said one basic bandwidth.
(FR)
Certains modes de réalisation de la présente invention concernent un procédé d’ajustement de taille de fenêtre de conflit (CWS) et un dispositif de réseau aux fins de transmission dans un spectre sans licence. Le procédé comprend : la réception d’une pluralité de réponses de HARQ, un canal de liaison descendante correspondant à la pluralité des réponses de HARQ occupant une ou plusieurs largeurs de bande de base dans une unité de temps de référence ; la détermination du nombre de réponses de HARQ dans une largeur de bande de base ; et l’ajustement, sur la base du rapport de NACK dans ladite largeur de bande de base, d’une CWS correspondant à ladite largeur de bande de base.
(ZH)
本公开的一些实施例提供了一种非授权频谱传输中CWS调节方法和网络设备。所述方法包括:接收多个HARQ应答,上述多个HARQ应答对应的下行信道在参考时间单元内占用一个和/或多个基本带宽;确定一个基本带宽的HARQ应答数量;基于所述一个基本带宽内NACK的比率,调节所述一个基本带宽对应的CWS。
