Abstract

To optimize latency and throughputs in 802.11 network implementing multi-link P2P communication sessions on multiple P2P links, a P2P TID-To-Link mapping specific to the multiple P2P links and defining a mapping of TIDs to the multiple P2P links is negotiated between the two peer non-AP MLDs of the session. The P2P TID-To-Link map is carried in a TID-to-Link Mapping information element, IE, according to the IEEE 802.11be/D2.0 standard that is included in exchanged TDLS Action frames, e.g. when establishing multiple single-link TDLS direct links. The MLDs check whether a proposed P2P TID-To-Link mapping received from the peer MLD matches its own TID-To-Link mapping with an AP MLD. Once the P2P TID-To-Link mapping is agreed on, the peer MLDs directly communicate through the multiple P2P links based on the negotiated TID-to-Link mapping.

Abstract

Single link TDLS direct link according to IEEE 802.11be/D2.0 does not benefit from the multiple link features to improve aggregation, common block acknowledgement and retransmission through plural links. The invention provides multi-link TDLS direct link by augmenting TDLS Action frames exchanged during TDLS direct link establishment. The augmented frames signal plural TDLS links from amongst multiple setup communication links of the emitting non-AP MLD. Those links are intended links on which to establish the TDLS direct link. The other peer non-AP MLD can, through the frame exchange, negotiate another set of links. In embodiments, an augmented TDLS Multi-Link IE embeds Per-TDLS STA Profiles, each of which signals a specific TDLS link. A Profile conveys a Link ID and a MAC address of the corresponding affiliated STA of the transmitting non-AP MLD. The non-AP MLDs therefore share their affiliated STAs' MAC addresses, hence simplifying the signaling in the P2P data frames.

Abstract

The invention improves user privacy in wireless networks by making fingerprinting of management frames more difficult. It is achieved by obfuscating the IEs that populate a management frame. Some IEs to be included in the management frame are grouped into sets; each set of one or more IEs is encrypted into an encrypted portion; each encrypted portion is embedded within the information part of a new IE, acting as a container. One or more of such Container IEs are then embedded in the frame body of the management frame under construction. The management frame can then be transmitted. By changing obfuscating parameters used to build the Container IEs, when the station changes its own MAC address based on a RCM procedure, the same frame, such as a beacon frame, can have a very different fingerprint after the MAC address change. Fingerprint-based correlation between frames is therefore made more difficult.
