Assignee: MEDIATEK SINGAPORE PTE. LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A method, comprising:
communicating, by a processor of a first apparatus, with a second apparatus via a first link in a first frequency band and via a second link in a second frequency band different than the first frequency band by performing operations comprising:
performing an independent enhanced distributed channel access (EDCA) on each of the first link and the second link;
obtaining a transmit opportunity (TXOP); and
refraining from either transmitting on the first link and receiving on the second link simultaneously or receiving on the first link and transmitting on the second link simultaneously,

wherein the first apparatus functions as an access point (AP) multi-link device (MLD),
wherein the second apparatus functions as a non-simultaneous-transmit-and-receive (NSTR) non-AP MLD,
wherein a synchronizing of either or both of a starting time and an ending time of a transmission and a reception on the first link and the second link comprises aligning an ending time of a downlink (DL) Physical Layer Conformance Procedure (PLCP) Protocol Data Unit (PPDU) carrying a frame that solicits a response simultaneously sent to the second apparatus on the first link and the second link, and
wherein a difference between a first ending time of a first transmission on the first link and a second ending time of a second transmission on the second link is less than a short inter-frame space (SIFS).
