Synchronized group messaging
First Claim
1. A method for synchronizing wireless communications, comprising:
- receiving access point information, the access point information including one or more of;
a load on at least one second access point, wireless channel information, or an identification of multicast streams to be used for synchronized wireless communications;
determining, by a first access point, a common transmission time for synchronous wireless communications by a group of access points based on the access point information, the group of access points including the first access point and the least one second access point;
transmitting, by the first access point, a trigger frame to the group of access points prior to the common transmission time, the trigger frame indicating the common transmission time; and
transmitting, by the first access point, based on the common transmission time, a first wireless communication to at least one first wireless communication device synchronously with at least one second wireless communication from the at least one second access point to at least one second wireless communication device.

Abstract
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.

9. A method for synchronizing wireless communications, comprising:
-
determining, by a first access point, a common transmission time for synchronous wireless communications by a group of access points, the group of access points including the first access point and at least one second access point; transmitting, by the first access point, a trigger frame to the group of access points prior to the common transmission time, the trigger frame indicating the common transmission time; and transmitting, by the first access point, based on the common transmission time, a first wireless communication to at least one first wireless communication device synchronously with at least one second wireless communication from the at least one second access point to at least one second wireless communication device; and transmitting group messaging transmit time offset information, wherein; the group of access points is a first group of access points; the synchronous wireless communications including the trigger frame and the first wireless communication are transmitted on a first primary wireless channel of the first group of access points; and the group messaging transmit time offset information identifies at least one second common transmission time associated with at least one second group of access points operating on at least one second primary wireless channel different than the first primary wireless channel.
