Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may transmit, to a second AP and during a first portion of a transmission opportunity (TxOP), a request to participate in a multi-user (MU) transmission. The AP may receive, from the second AP and during the first portion of the TxOP, an indication of intent to participate in the MU transmission during the second portion of the TxOP, the indication of intent including a resource request of the second AP for participation in the MU transmission. The AP may transmit, during an initial period of the second portion of the TxOP, a trigger signal to the second AP indicating a set of one or more resources for the second AP during the MU transmission. The AP may participate, in conjunction with the second AP and during the second portion of the TxOP, in the MU transmission.

Abstract: This disclosure provides methods, devices and systems for generating packet preambles. Some implementations more specifically relate to preamble designs for special cases such as, for example, full-bandwidth multi-user multiple-input multiple-output (MU-MIMO), single-user (SU) preamble puncturing, hybrid automatic repeat request (HARD), and multi-AP coordination. Multi-AP coordination may refer to coordinated beamforming (CoBF), joint transmission (JT), or coordinated orthogonal frequency division multiple access (C-OFDMA). Additionally, or alternatively, some implementations more specifically relate to preamble designs that accommodate signal fields of different cases.

Abstract: This disclosure provides methods, devices and systems for wireless communication, and particularly, methods, devices and systems for generating or receiving a wireless packet that includes a first preamble based on a first generation of a wireless communication protocol and a second preamble based on a second generation of the wireless communication protocol. The wireless packet may include the first preamble in a first subchannel of a wireless channel and the second preamble in a second subchannel of the wireless channel. Thus, the wireless packet may concurrently include communication to or from different types of wireless stations that support the different generations of a wireless communication protocol.
