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

Claim 0:
1. 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
synchronizing 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,

wherein a physical carrier sense (CS) is checked during a point coordination function (PCF) inter-frame space (PIFS),
wherein the synchronizing of either or both of the starting time and the ending time of the transmission and the reception on the first link and the second link comprises:
calculating a first minimum transmission time of a response frame based on a transmit vector (TXVECTOR) parameter of a soliciting Physical Layer Conformance Procedure (PLCP) Protocol Data Unit (PPDU) on the first link;
calculating a second minimum transmission time of the response frame based on another TXVECTOR parameter of another soliciting PPDU on the second link;
determining either the first minimum transmission time or the second minimum transmission time, whichever is higher, to be a transmission time of the response frame;
applying a Medium Access Control (MAC) layer padding, a physical (PHY) layer padding, or both, on the first link and the second link in determining the transmission time; and
transmitting the response frame at the transmission time on the first link and the second link.
