US 2023/0147311 A1 · ENHANCED HANDOVER FOR MOVING WI-FI MULTI-LINK DEVICES

Abstract

This disclosure describes systems, methods, and devices related to multi-link devices (MLDs). A MLD may identify a first security key received from a first access point MLD (A-MLD); identify a second security key received from the first A-MLD; transmit, from a first physical location, a first packet to the first A-MLD, the first packet including the first security key; identify a first subset of N packets, the first subset received from the first A-MLD; transmit, from a second physical location, a second packet to the second A-MLD, the second packet including the second security key; identify a second subset of the N packets, the second subset received from the second A-MLD; determine that a third packet of the N packets was not received; and transmit, to the first A-MLD or the second A-MLD, an indication that the third packet was not received.

Dependent claims

An apparatus of a multi-link device (MLD), the apparatus comprising processing circuitry coupled to storage, the processing circuitry configured to:

identify a first security key received from a first access point MLD (A-MLD), the first security key associated with communicating with the first A-MLD;
identify a second security key received from the first A-MLD, the second security key associated with communicating with a second A-MLD;
transmit, from a first physical location, a first packet to the first A-MLD, the first packet comprising the first security key;
identify a first subset of N packets, the first subset received from the first A-MLD;
transmit, from a second physical location, a second packet to the second A-MLD, the second packet comprising the second security key;
identify a second subset of the N packets, the second subset received from the second A-MLD;
determine, based on sequence numbers included in the first subset and the second subset, that a third packet of the N packets was not received;
and
transmit, to the first A-MLD or the second A-MLD, an indication that the third packet was not received.

A computer-readable storage medium comprising instructions to cause processing circuitry of a controller device of a first access point (AP) multi-link device (A-MLD) and a second A-MLD, upon execution of the instructions by the processing circuitry, to:

generate a first security key for communications between a MLD the first A-MLD;
generate a second security key for communications between the MLD the second A-MLD;
transmit the first security key and the second security key to the first A-MLD or the second A-MLD to forward to the MLD;
generate N packets having respective sequence numbers;
transmit the N packets to both the first A-MLD and the second A-MLD;
transmit first instructions to the first A-MLD to transmit a first subset of the N packets to the MLD;
transmit second instructions to the second A-MLD to transmit a second subset of the N packets to the MLD;
identify a first score received from the first A-MLD, the first score indicates that a first packet of the N packets was not received by the MLD;
and
identify a second score received from the second A-MLD, the second score indicates that a second packet of the N packets was not received by the MLD.
