    Abstract: An embodiment is a method performed by a source node to activate relay functionality of a relay node on a per-physical layer protocol data unit (PPDU) basis. The method includes generating a PPDU that includes a first set of preamble fields, followed by a relay-on field indicating that the relay node should relay the PPDU, followed by a second set of preamble fields, followed by a data field that includes a frame intended for a destination node, wherein the first set of preamble fields includes a first legacy short training field (L-STF) field, a first legacy long training field (L-LTF) field, and a first legacy signal (L-SIG) field, wherein the second set of preamble fields includes a second L-STF field, a second L-LTF field, and a second L-SIG field. The method further includes transmitting the PPDU.

    Abstract: An embodiment is method performed by a source node to transmit data that is to be relayed by a relay node to a destination node using a multi-link device (MLD) amplify-and-forward (AF) relay mechanism. The method includes transmitting a relay trigger frame to the relay node on a first link between the source node and the relay node to set up a second link between the relay node and the destination node, receiving a relay response frame from the relay node on the first link as a response to the relay trigger frame, transmitting a relay initiation frame to the relay node on the first link to start a relay operation period, and during the relay operation period, transmitting a data frame on the first link that is to be relayed by the relay node to the destination node on the second link using an AF relay mechanism.

    Abstract: Disclosed herein is a method performed by a wireless device in a wireless network. The method includes wirelessly transmitting an aggregated physical layer protocol data unit (A-PPDU), wherein the A-PPDU includes a plurality of sub-PPDUs each occupying a different one of a plurality of subchannels, wherein all of the plurality of sub-PPDUs are addressed to a same station (STA). The A-PPDU may be used for realizing an efficient channel sounding process for a subchannel selective transmission (SST).
