Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may use wireless local area network (WLAN) signaling fields in a multiple user transmission preamble to communicate with a number of stations greater than a threshold. For example, the AP may determine that the number of stations is greater than the threshold and generate a compression indicator and an indication of the number of stations to include in a first signaling field. The AP may then generate a spatial configuration indicator in a second signaling field based on the number of stations and transmit the first and second signaling fields in a preamble of the multiple user transmission. Upon receiving the preamble, a station may identify the compression indicator and number of stations, and the spatial configuration indicator in the first and second signaling fields, and decode the multiple user transmission using a determined spatial decoding scheme.

Abstract: The present disclosure provides various aspects related to techniques for generating trigger frames, at an access point (AP), that reduce the overhead associated with triggering an uplink transmission from the wireless station (STA). Features of the present disclosure achieve this by, for example, utilizing a single per-user information field of the trigger to signal a plurality of random access resource units that may be allocated to the one or more STAs in the network. Such a technique is an improvement over the conventional system that require each random access resource unit to be signaled separately in a separate per-user information field (thus increasing the overhead). Additionally, aspects of the present disclosure allow the AP to effectively signal to the STA whether the one or more resources allocated to the at least one STA are a single user resource unit allocation or a multi-user resource unit allocation.

Abstract: A wireless device may selectively add padding to an end of a data transmission in order to provide adequate time for a receiving device to process the transmitted data and transmit feedback related to the transmitted data. A wireless device may identify a total amount of data capable of being transmitted in a transmission, and determine a number of data bits to be transmitted in the transmission. An amount of padding may be selected based on a proportion of the total amount of data capable of being transmitted and the number of data bits. In some examples, a preamble for a feedback transmission may be transmitted concurrently with processing of the received transmission.
