Abstract: Seamless client roaming for Multi-Link Device (MLD) clients may be provided. First, a Traffic Identifier (TID)-to-link map may be established by an Upper Service Access Point (U-SAP) of a multi-AP MLD entity that assigns subsets of TIDs to at least two links of the entity. For example, a client device logically associates with the U-SAP, while the client device physically connects to a first and second AP of the entity on a respective first and second link, where the first and second AP include first and second Lower Service Access Points (L-SAPs) and are non-collocated. Next, using the map, data received at the U-SAP is directed over one of the two links for transmission to the client device. Further, frame aggregation and block acknowledgment functions may be performed by one of the first or second L-SAP based on whether data transmission is over the first or second link.

The second subset of the bandwidth range may be smaller than the first subset of the bandwidth range.

Abstract: Techniques for triggering multiple basic service sets (BSSs) to share resources for a coordinated transmission are described. One technique includes determining a first amount of data available to send in a first BSS and determining a second amount of data available to send in a second BSS. The first BSS and the second BSS form an overlapping BSS. An amount of resources in the first BSS that is available to share with the second BSS for a coordinated transmission from the first BSS and the second BSS is determined based on the first amount of data and the second amount of data. A frame that includes an indication of the amount of resources is generated and transmitted to at least one of the first BSS and the second BSS.

Abstract: The embodiments herein use a factorization based technique for determining filter coefficients for a subset of the subcarriers in a wireless frequency band. Once the filter coefficients for the subset of the subcarriers are calculated, the network device uses these filter coefficients to identify the filter coefficients in a neighboring subcarrier. To do so, the network device uses pseudo-inverse iteration to convert the already calculated filter coefficients into filter coefficients for a neighboring subcarrier. The network device can repeat this process for the next set of neighboring subcarriers until all the filter coefficients have been calculated.
