SYNCHRONIZED GROUP MESSAGING

摘要

Devices and methods for synchronized group messaging in a wireless communication system are described. Multicast transmissions, such as those in a dense network, can cause significant medium usage because same multicast packet is likely sent by multiple APs at different time. Medium usage in such implementations may be redundant. As such, the transmission medium is not used optimally. Devices and methods which coordinate and align group messages (e.g., multicast packets) amongst APs are described. Each AP may be configured to transmit identical packets at the same time. Therefore, medium usage can be reduced, while the range can be extended due to accumulated energy from APs.

1. A method of wireless communication, the method comprising:
identifying a transmission time for transmitting a message to a recipient via a first wireless communication transmitter, wherein contents of the message is to be transmitted to at least one other recipient via a second wireless communication transmitter; identifying common group messaging parameters associated with the first wireless communication transmitter and the second wireless communication transmitter, the common group messaging parameters including a group temporal key, a common transmission media access control address, and a common group identifier; generating the message based at least in part on the common group messaging parameters, wherein contents of the message to be transmitted to the recipient is the same as contents of the message transmitted to the at least one other recipient; and transmitting the message at the identified transmission time to the recipient.
