Abstract: Systems and methods are disclosed for a wireless device to transmit or receive a channel busy time (CBT) to or from other devices in a wireless network. For transmitting, the wireless device may determine a CBT during which a wireless channel is to be occupied, generate a universal reservation signal (URS) indicating the CBT, and transmit on the wireless channel the URS to at least one other wireless device. For receiving, the wireless device may receive on a wireless channel a URS from a second wireless device, the URS configured to indicate the CBT. The wireless device may also refrain from attempting to transmit on the wireless channel during the CBT.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may configure one or more trigger frames, which may include a number of random access resource units (RUs). A number of stations (STAs) may contend to use such random access RUs. Regulation techniques for which STAs may contend for access to random access RUs may include providing that separate subsets of random access RUs may be identified for STAs that are associated and unassociated with the AP. In some implementations, the regulation techniques enable STAs to attempt transmissions using the random access RUs when uplink-limited or if the STA has a non-empty buffer, or combinations thereof. Techniques for acknowledging receipt of an uplink transmission may include transmitting an acknowledgment using a same association identification for the acknowledgment as used in the uplink transmission, and including a STA identifier in a signaling field associated with the acknowledgment.

Abstract: Techniques are described herein that illustrate a feedback system to configure various format parameters of physical layer convergence procedure protocol data units (PPDUs) transmitted across a communication link. A receiving device may determine a Doppler shift or a delay spread of a signal received from a transmitting device. The receiving device may determine one or more format parameters for a future PPDU based on the Doppler shift or the delay spread. The receiving device may transmit an indication that includes the format parameters for the future PPDU to the transmitting device. The transmitting device may modify one or more format parameters of a PPDU based on the information in the indication. In some cases, the receiving device may indicate characteristics of mid-ambles, a type of PPDU, a guard interval, high efficiency long training field size for a future PPDU.

Abstract: Wireless communications systems and methods related to signaling medium reservation information medium sharing among multiple radio technologies (RATs) are provided. A first wireless communication device communicates, with a second wireless communication device, a reservation signal to reserve a transmission opportunity (TXOP) in a spectrum. The spectrum is shared by multiple RATs. The reservation signal includes a plurality of first waveform sequences indicating medium reservation information detectable by the multiple RATs. The first wireless communication device and the second wireless communication device are associated with a first RAT of the multiple RATs. The first wireless communication device communicates, with the second wireless communication device using the first RAT, a communication signal in the spectrum during the TXOP.

Abstract: Methods, systems, and devices for wireless communication are described. An access point (AP) may broadcast or multicast a wakeup transmission to wakeup radios (WURs) of a group of wireless and determine to retransmit the first wakeup transmission (e.g., for redundancy). The AP may transmit a second wakeup transmission to the WURs, the second wakeup transmission including an indication that the second wakeup transmission is a retransmission of the first wakeup transmission. The wireless devices may receive the indication that the second wakeup transmission is a retransmission, and may power up a main radio to receive a beacon based on whether or not the previous or originally wakeup transmission was received (e.g., determined via the indication included in the received wakeup message). In some cases, the AP may identify that some wireless devices failed to receive the first wakeup transmission, and may transmit a second wakeup transmission to those identified stations.

Abstract: A station configured to operate in a wireless network includes low-power protocol circuitry configured to operate according to a low-power protocol coupled to primary protocol circuitry configured to operate according to a first protocol. The low-power protocol circuitry includes a wake-up receiver configured to transition into a receive mode according to a medium access schedule. The wake-up receiver is also configured to receive synchronization signals from a wake-up transmitter of an access point in the wireless network. Each synchronization signal is received according to a slot-skipping transmit schedule of the wake-up transmitter. The low-power protocol circuitry also includes a low-power processor configured to synchronize a clock of the wake-up receiver to a clock of the wake-up transmitter based on at least one of the synchronization signals.
