Detailed Description

Test the transmission of UL frames from EMLSR clients.

This test considers an AP MLD and a non-AP MLD that support EMLSR. The non-AP MLD setups three links, while the set of EMLSR links is configurable. Block ack agreements (for TID 0) for both DL and UL directions are established after that the EML Operating Mode Notification frames are exchanged to enable the EMLSR mode on the EMLSR links. Aux PHYs on the EMLSR client do not switch link, hence the main PHY will switch link (if needed) when terminating a TXOP.

It is checked that:

Initially, aux PHYs are configured so that they are unable to transmit frames. Before generating the packets for the first UL data frame, transmissions on the link where the main PHY is operating and on the non-EMLSR link (if any) are blocked. Thus, the first UL data frame is held until transmissions on the link where the main PHY is operating are unblocked. The first UL data frame is sent by the main PHY without RTS protection. When the data frame exchange terminates, the MediumSyncDelay timer is started on the other EMLSR links and the CCA ED threshold is set as expected
If there is a non-EMLSR link, another data frame can be sent concurrently (without protection) on the non-EMLSR link
When the first UL data frame is transmitted, we make the aux PHYs on the EMLSR client capable of transmitting, we block transmissions on the link where the main PHY is operating and generate new UL packets, which will then be transmitted on a link where an aux PHY is operating. Thus, the aux PHY transmits an RTS frame and the main PHY will take over and transmit the second UL data frame. We check that, while the link on which the main PHY was operating is blocked because another EMLSR link is being used, new backoff values for that link are generated if and only if the QosTxop::GenerateBackoffIfTxopWithoutTx attribute is true; otherwise, a new backoff value is generated when the link is unblocked.
When the exchange of the second UL data frame terminates, we make the aux PHY unable to transmit, block transmissions on the non-EMLSR link (if any) and generate some more UL packets, which will then be transmitted by the main PHY. However, a MediumSyncDelay timer is now running on the link where the main PHY is operating, hence transmissions are protected by an RTS frame. We install a post reception error model on the AP MLD so that all RTS frames sent by the EMLSR client are not received by the AP MLD. We check that the EMLSR client makes at most the configured max number of transmission attempts and that another UL data frame is sent once the MediumSyncDelay timer is expired. We also check that the TX width of the RTS frames and the UL data frame equal the channel width used by the main PHY.
We check that no issue arises in case an aux PHY sends an RTS frame but the CTS response is not transmitted successfully. Specifically, we check that the main PHY is completing the channel switch when the (unsuccessful) reception of the CTS ends and that a new RTS/CTS exchange is carried out to protect the transmission of the last data frame.
While the main PHY is operating on the same link as an aux PHY (which does not switch channel), the aux PHY is put in sleep mode as soon as the main PHY starts operating on the link, stays in sleep mode until the TXOP ends and is resumed from sleep mode right after the end of the DL/UL TXOP.
When an aux PHY that is not TX capable gains a TXOP, it checks whether the main PHY can switch to the auxiliary link a start an UL TXOP. If the main PHY is switching, the aux PHY waits until the channel switch is completed and checks again; if the remaining backoff time on the preferred link is greater than the channel switch delay, the main PHY is requested to switch to the auxiliary link of the aux PHY. When the channel switch is completed, if the medium is idle on the auxiliary link and the backoff is zero, the main PHY starts an UL TXOP after a PIFS period; otherwise, the main PHY starts an UL TXOP when the backoff timer counts down to zero. The QoS data frame sent by the main PHY is not protected by RTS and the bandwidth it occupies is not affected by possible limitations on the aux PHY TX bandwidth capabilities.

Also, if the PutAuxPhyToSleep attribute is set to true, it is checked that aux PHYs are in sleep mode a SIFS after receiving the ICF and are still in sleep mode right before receiving a Block Ack frame, and they are resumed from sleep after receiving the Block Ack frame.
