Abraham teaches the method of claim 1, wherein the acknowledgment message further indicates one or more links other than the third link (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams). Regarding claim 5. Abraham teaches the method of claim 1, wherein: the first link corresponds to a first frequency channel (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams); the second link corresponds to a second frequency channel different from the first frequency channel (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams); and the third link corresponds to a third frequency channel different from the first frequency channel and different from the second frequency channel (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams). Regarding claim 6. Abraham teaches the method of claim 1, further comprising transmitting the second data unit concurrently with transmitting the first data unit (Abraham, pp [22]-[23], [25]: concurrent data streams). Regarding claim 7. Abraham teaches the method of claim 1, further comprising: transmitting, to the second wireless device and via the first link, a response message to the acknowledgment message (Abraham, Fig. 16, pp [113]-[116]). Regarding claim 8. Abraham teaches the method of claim 1, further comprising: monitoring, during transmission of the first data unit, the first link for the acknowledgment message (Abraham, Fig. 16, pp [113]-[116]). Regarding claim 10. Abraham teaches the method of claim 9, wherein the second data unit further indicates the third link (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams). Regarding claim 11. Abraham teaches the method of claim 9, wherein the second data unit further indicates a plurality of links comprising the third link, and wherein the method further comprises: transmitting, to the second wireless device and via the first link, a response message indicating a selection of the third link among the plurality of links (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams). Regarding claim 12. Abraham teaches the method of claim 9, wherein: the first link corresponds to a first frequency channel (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams); the second link corresponds to a second frequency channel different from the first frequency channel (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams); and the third link corresponds to a third frequency channel different from the first frequency channel and different from the second frequency channel (Abraham, Figs. 7, 8 and 9, pp [87]-[89]: multiple data streams). Regarding claim 13. Abraham teaches the method of claim 9, wherein the first data unit comprises a physical layer protocol data unit (PPDU), and wherein the error comprises at least one of: an error in a physical layer (PHY) header of the PPDU (Abraham, pp [22]-[23], [25], [29], [57]); or an error in a medium access control (MAC) protocol data unit (MPDU) of the PPDU (Abraham, pp [22]-[23], [25], [29], [57]). Regarding claim 14. Abraham teaches the method of claim 9, wherein the third data unit comprises a part, of the first data unit, that comprises the error during the transmission of the first data unit. Regarding claim 15.

Regarding claim 20. Abraham teaches the method of claim 16, wherein the first data unit comprises a physical layer protocol data unit (PPDU), and wherein the error comprises at least one of: an error in a physical layer (PH Y) header of the PPDU (Abraham, pp [22]-[23], [25], [29], [57]); or an error in a medium access control (MAC) protocol data unit (MPDU) of the PPDU (Abraham, pp [22]-[23], [25], [29], [57]). References related but not used in the rejection above Kim et al. (Pub. No. US 2017/0353887), teaches a method and device for transmitting a frame including error check bits for a header in a wireless LAN are disclosed. The method for transmitting a frame in a wireless LAN can comprise the steps of: generating, by an STA, a frame to be transmitted to an AP; and transmitting, by the STA, the frame to the AP, wherein the frame is an A-MPDU, the A-MPDU includes an A-MPDU header subframe and an A-MPDU subframe, the A-MPDU header subframe includes a first MPDU, the A-MPDU subframe includes a second MPDU, the first MPDU, as an MPDU, includes a first MAC header, expect for a MAC body, and the second MPDU, as an MPDU, can include the MAC body and a second MAC header. Vermani et al. (Pub. No. US 2022/0140942) teaches methods, devices and systems for interpreting reserved bits and values associated with different releases of a wireless communication protocol. A wireless communication device may determine whether to terminate or continue reception of a physical layer protocol convergence protocol (PLCP) protocol data unit (PPDU) if it detects a reserved bit in the physical layer preamble set to an unsupported value (such as a value different than what is defined by a version or release of the wireless communication protocol supported by the wireless communication device). A wireless communication device may determine whether to terminate or continue reception of a PPDU if it detects a field in the physical layer preamble set to a reserved value (such as defined by a version or release of the wireless communication protocol supported by the wireless communication device).
