Abstract: A method to implement an adaptive multicast data rate transmission selection includes determining the lowest signal strength station in a multicast group, using signal strength as an indicator to increase data rate, and determining if the increase in data rate is viable for multicast transmission by determining frame or packet loss using the increased data rate.

Abstract translation: 实现自适应多播数据速率传输选择的方法包括：使用信号强度作为指标来确定多播组中的最低信号强度站，以增加数据速率，以及通过确定帧来确定数据速率的增加对于多播传输是否可行 或使用增加的数据速率的分组丢失。

Abstract: A method and apparatus for power management in the communication system, wherein the method for transmitting data from an access point to communication units comprising: assigning, by the access point, a first and a second association identifier in a message, to each of the communication units, to indicate the presence of respective buffered multicast data and unicast data respectively; setting, by the access point, the first association identifier to indicate the corresponding communication unit to receive the buffered multicast data, the second association identifier to indicate the corresponding communication unit to receive the buffered unicast data; and transmitting, by the access point, the message to awake the communication unit corresponding to the set first and/or second association identifier so as to transmit the buffered data thereto.
