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

Claim 9:
10. An apparatus, comprising:
a transceiver configured to communicate wirelessly; and
a processor coupled to the transceiver and configured to perform operations comprising:
establishing, via the transceiver, 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 or on at least a first link and a second link; and
performing, via the transceiver, an extreme-high-throughput (EHT) subchannel selective transmission (SST) operation in the plurality of frequency segments or on the first link and the second link 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 or on the first link prior to the TWT SP;
switching to a second frequency segment of the plurality of frequency segments or the second link to perform a second data transmission on the second link during the TWT SP; and
switching back to the first frequency segment or the first link to perform a third data transmission on the first link after the TWT SP,

wherein the negotiating of the TWT SP comprises either:
indicating one of the plurality of frequency segments as containing a resource unit (RU) allocation addressed to the non-AP STA; or
indicating one of the first link and the second link on which an operating frequency segment is located during the TWT SP,

wherein, in indicating the one of the first link and the second link on which the operating frequency segment is located, the processor performs operations comprising:
indicating the one of the first link and the second link by setting a respective bit of a plurality of bits in a Link identifier (ID) subfield in a TWT Channel field in a TWT element corresponding to the one of the first link and the second link to 1;
indicating the operating frequency segment among a plurality of frequency segments within a basic service set (BSS) bandwidth by setting a respective bit of a plurality of bits in an Operating Channel Bitmap subfield in the TWT Channel field corresponding to the operating frequency segment to 1; and
indicating a packet detection channel of the non-AP STA during the TWT SP by setting a respective bit of a plurality of bits in a Packet Detection Channel Bitmap subfield in the TWT Channel field corresponding to a 20-MHz operating channel in one of the plurality of frequency segments to 1 such that packet detection is performed by the non-AP STA in the 20-MHz operating channel.
