Abrégé
(EN)
The invention provides a self-adaption mode switching method and system based on MCS and a bler. When intra-mode switching is carried out in a transmission mode TM3 in a base station, the MCS and the bler are imported as judgment thresholds. The method comprises following steps of receiving ACK/NACK information of downlink data reported by a physical layer; calculating a downlink bler; judging whether RI and CQI reach adjustment thresholds or not; judging whether the bler and MCS reach the adjustment thresholds or not after the RI and CQI reach the adjustment thresholds; calculating new downlink MCS as the MCS value of a next moment after the bler and MCS reach the adjustment thresholds; and carrying out intra-mode switching adjustment and downlink MCS adjustment. According to the method and the system, the downlink bler of the terminal and the current MCS of the terminal are added to the mode switching judgment threshold constraint, and through combination of generally used RI and CQI thresholds, the downlink traffic when switching is carried out in the TM3 mode is stable.

本发明提出一种基于MCS和bler的自适应模式切换方法及系统,在基站内传输模式TM3下进行模式内切换时引入MCS及bler作为判决门限,包括接收物理层上报的下行数据的ACK/NACK信息,计算下行bler,判断RI及CQI是否达到调整门限,达到门限后进断bler及MCS是否达到调整门限,达到门限后计算新的下行MCS,作为终端下一时刻的MCS值,进行模式内切换调整及下行MCS调整。本发明通过将终端下行的bler及终端当前的MCS添加到模式切换的判决门限约束当中,结合普遍采用的RI及CQI门限,达到TM3模式内切换下行流量平稳的目的。
