Abstract: A method for multi-antenna processing in multi-link wireless communication systems includes transmitting by a first MLD, a first capability defining a first number of Spatial Streams (SS) supported by the first MLD for a single link exchange over one of a subset of links from a plurality of links between the first MLD and a second MLD. A second capability is transmitted by the first MLD defining a second number of SS supported by the first MLD for each link of a multi-link exchange. At least one Radio Frequency (RF) chain of the first MLD is configured to enable communication over the subset of links from the plurality of links.

Abstract: A method for securing a Wi-Fi link in a wireless communication system includes configuring an existing agent with a controller, wherein the existing agent is configured as a first Basic Service Set (BSS). An enrollee agent is onboarded with a Push Button Configuration (PBC) method to establish an 1905 layer security between the existing agent and the enrollee agent. The enrollee agent is configured with the controller, including the controller transmitting a Device Provisioning Protocol (DPP) Bootstrapping Information Request to the enrollee agent and the controller receiving a DPP Bootstrapping Information Response from the enrollee agent, wherein the enrollee agent is configured as a second BSS.

Abstract: A first data unit is transmitted which indicates to a remote device to transmit a second data unit. The first data unit comprises an indication to transmit a second data unit. The first data unit comprises a value which indicates that the remote device is to transmit the second data unit and does not indicate a protocol which defines a format of the second data unit. The protocol which defines the format of the second data unit is based on a protocol which defines a format of the first data unit. The second data unit is received from the remote device in response to the transmission of the first data unit.
