Classification: CPC H  Y | IPC H

Claim 0:
1. A method, comprising:
establishing communications between an access point (AP) and a non-AP station (STA) in a plurality of frequency segments within a basic service set (BSS) bandwidth; and
performing an extreme-high-throughput (EHT) subchannel selective transmission (SST) operation in the plurality of frequency segments by:
negotiating a trigger-enabled target wake time (TWT) session period (SP);
performing a first data transmission in a first frequency segment of the plurality of frequency segments prior to the TWT SP;
switching to a second frequency segment of the plurality of frequency segments to perform a second data transmission on a second link during the TWT SP; and
switching back to the first frequency segment to perform a third data transmission on a first link after the TWT SP,

wherein the negotiating of the TWT SP comprises indicating one of the plurality of frequency segments as containing a resource unit (RU) allocation addressed to the non-AP STA,
wherein the indicating of the one of the plurality of frequency segments as containing the RU allocation comprises indicating the one of the plurality of frequency segments by setting a respective bit of a plurality of bits in an Operating Channel Bitmap subfield in a TWT Channel field in a TWT element corresponding to the one of the plurality of frequency segments to 1,
wherein a length of the TWT Channel field is indicated by a TWT Channel Length subfield in a Control field in the TWT element,
wherein the length of the TWT Channel field is either 1 byte or 2 bytes,
wherein the TWT Channel Length subfield is set to 0 to indicate that the length of the TWT Channel field is 1 byte, and
wherein the TWT Channel Length subfield is set to 1 to indicate that the length of the TWT Channel field is 2 bytes.
