Abstract
Disclosed herein are devices, systems and methods between a between a plurality of collaborating Access Points (APs) and a receiving station (STA) operating in a wireless local area network (WLAN). The method include the steps of: transmitting, by each AP in the plurality of collaborating APs, a data frame to the receiving STA, each data frame has a preamble portion, the preamble portion including a signal (SIG) field, and the SIG field has a subfield including information representative of a total number of spatial streams transmitted by the plurality of collaborating Aps.
Claims16
A method comprising:
- transmitting, by an access point (AP), a downlink frame to a receiving station (STA), the downlink frame comprising a preamble portion including a signal (SIG) field, wherein the SIG field comprises a first subfield including information representative of a total number of Long Training Fields (LTF) symbols transmitted by a plurality of collaborating APs.
A method comprising:
- receiving, by a receiving station (STA), a downlink frame from an access point (AP), the downlink frame comprising a preamble portion including a signal (SIG) field, wherein the SIG field comprises a first subfield including information representative of a total number of Long Training Fields (LTF) symbols transmitted by a plurality of collaborating APs.
A method of communication between an access point (AP) and a receiving station (STA) operating in a wireless local area network (WLAN), the method comprising:
- transmitting, by the AP, a null data packet (NDP) frame to the receiving STA,
- wherein the NDP frame includes a SIG field, the SIG field including information representative of a Basic Service Set identifier (BSSID) configured to be used by the receiving STA to determine a correct NDP frame for estimating a feedback matrix during a sounding process between a respective AP and the receiving STA.
An access point (AP) comprising:
- at least one processor;
- and
- a non-transitory computer readable storage medium storing programming, the programming including instructions that, when executed by the at least one processor, cause the AP to:
- transmit a downlink frame to a receiving station (STA), the downlink frame comprising a preamble portion including a signal (SIG) field, wherein the SIG field comprises a first subfield including information representative of a total number of Long Training Fields (LTF) symbols transmitted by a plurality of collaborating APs.
