Abstract: Systems and methods are disclosed that may provide for selective multi-user uplink (UL) of data for wireless devices. For example, a first wireless device may request permission to initiate a UL transmission to a second wireless device. The first wireless device may then receive, from the second wireless device, permission to initiate the UL transmission according to a multi-user (MU) UL protocol, determine a threshold duration for the UL transmission, and transmit UL data to the second wireless device according to the MU UL protocol and the threshold duration.

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.

Abstract: Methods and systems for wireless communication are disclosed. In one aspect, a method includes generating device specific transmission control information for each of two devices, transmitting the transmission control information for each device over different frequencies, and transmitting data to each of the devices as part of a communication according to the respective transmission control information. In some aspects, the transmission control information for each device is encoded based on an identifier of the device. For example, in some aspects, an error detection value such as a cyclic redundancy check, is exclusive or'ed with an identifier of the device, such as an AID, PAID, or group identifier. The resulting value is transmitted along with the transmission control information. A device receiving the wireless frame may only be able to decode its own transmission control information, as the decoding is also based on the receiving device's identifier.
