Mechanisms for single user (SU) and multiple user (MU) transmission and association via polling within wireless communications
A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other device(s) and to generate and process signals for such communications. A device generates and transmits a resource and association poll frame (ra-poll frame) to other device(s). The contents of ra-poll frame direct which of the other device(s) is authorized to respond to the device (e.g., authorized device(s)) and the manner in which they are authorized to respond. Authorized device(s) transmit responses that may include association request(s) and/or a resource request(s), among other types of communications. The device then generates and transmits acknowledgement(s) (ACK(s)) indicates successful receipt of any responses from the authorized device(s).
