Abstract: Methods and apparatus are described herein for dynamic allocation of multiple channels and data streams for multi-channel transmission and multiple-input and multiple-output (MIMO). For example, a station (STA) may receive an enhanced poll (EPoll) frame that includes a time offset, a channel offset and antenna/sector settings from an access point (AP). The STA may transmit, based on the received EPoll frame, an enhanced service period request (ESPR) frame that includes a MIMO control field and a multi-channel control field. The MIMO control field may indicate whether the STA supports MIMO transmission. The multi-channel control field may indicate whether the STA supports multi-channel transmission. Upon transmitting the ESPR frame, the STA may receive an enhanced grant frame from the AP. The enhanced grant frame may include an antenna configuration and a multi-channel allocation to enable the STA to perform the MIMO transmission and the multi-channel transmission.

Abstract: A method for use in an IEEE 802.11 station (STA) for receiving data from an IEEE 802.11 access point (AP) via a coordinated orthogonal block resource allocation (COBRA) is described. The STA may receive a COBRA schedule from the AP and transmit an acknowledgement (ACK) to the AP in the COBRA TXOP. The STA may receive a first data packet in the COBRA TxOP based on the COBRA schedule. The STA may determine whether the first data packet is received successfully and on a condition that the first data packet is not received successfully, the STA may transmit a negative acknowledgement (NACK) to the AP in the COBRA TxOP.

Abstract: Systems, methods, and instrumentalities are disclosed for concurrent link setup and downlink data retrieval, e.g., for high efficiency WLAN. An access point (AP) may send a trigger element that allocates a resource for pre-association transmissions with the AP. The trigger element may allocate the resource for random access and/or deterministic access. The AP may receive, from an unassociated STA, a first frame via one or more resource units (RUs) allocated in the trigger element. The AP may determine a pre-association identifier (PID) that identifies the unassociated STA. The AP may send the PID to the unassociated STA, for example, in the trigger element or in the multi-STA ACK. The AP may send a second frame associated with a multi-user (MU) transmission that includes the PID. The AP may send a trigger frame that includes the PID.
