Wireless network multipoint association and diversity
Aspects of the disclosure relate to a multipoint environment that enables a station (STA) to communicate with multiple access points (APs) and an AP to communicate with multiple STAs in a single wireless protocol stack. For example, a STA can authenticate simultaneously with multiple APs and decode any data packet that includes in a header a destination address that matches an address of the STA, irrespective of the source address included in the header of the data packet. Similarly, an AP can decode any data packet that includes in a header a source address that matches an address of an authenticated STA, irrespective of the destination address included in the header of the data packet.
1. A wireless computing device comprising:
an antenna; and
a processor in communication with the antenna, wherein computer-executable instructions, when executed by the processor, cause the wireless computing device to:
authenticate with one or more access points;
decode a first portion of a first packet transmitted by a first access point in the one or more access points, wherein an active set for the wireless computing device identifies the first access point as serving the wireless computing device;
determine that a destination address included in the first portion of the first packet matches an address of the wireless computing device;
process the first packet in response to the determination that the destination address included in the first portion of the first packet matches the address of the wireless computing device, irrespective of a source address included in the first portion of the first packet; and
decode a first portion of a second packet transmitted by a second access point in the one or more access points, wherein the active set is updated to identify the second access point as serving the wireless computing device in response to transmission of the second packet.
2. The wireless communication device of claim 1 , wherein the computer-executable instructions, when executed, further cause the wireless communication device to:
decode a first portion of a third packet transmitted by the first access point;
determine that a destination address included in the first portion of the third packet does not match an address of the wireless computing device; and
begin to search for a new packet transmitted by any access point in the one or more access points before transmission of the third packet is complete.
3. The wireless communication device of claim 1 , wherein the second access point transmits the second packet in response to a transmission of the second packet by the first access point failing.
4. The wireless communication device of claim 3 , wherein the second access point is located at a position spatially different than a position of the first access point.
5. The wireless communication device of claim 3 , wherein the first access point and the second access point are both configured to transmit data to the wireless communication device using a same wireless protocol stack.
6. The wireless communication device of claim 3 , wherein an access point controller pre-caches the second packet at the second access point device prior to a transmission of the second packet by the first access point.
7. The wireless communication device of claim 3 , wherein the second access point causes a scheduler to receive a beam visibility report indicating that the second access point is transmitting data to the wireless communication device instead of the first access point, wherein the scheduler schedules a third packet intended for the wireless communication device to be transmitted by the second access point instead of the first access point in response to receipt of the beam visibility report.
8. The wireless communication device of claim 1 , wherein the first portion of the first packet comprises one of a header of the first packet or a preamble of the first packet.
9. The wireless communication device of claim 1 , wherein the wireless communication device is a station.
10. The wireless communication device of claim 1 , wherein the first access point transmits the first packet during a non-assigned raster interval.
