Abstract: Methods, systems, and devices are described for signaling soft time division multiplexing (TDM) assignment information in an enhanced distributed channel access (EDCA) operation. The soft TDM assignment may be sent to one or more nodes of a group of nodes to communicate with indicated priority access parameters during at least one of a plurality of time slots. The soft TDM assignment may also convey one or more backoff operation rules to at least one of the one or more nodes. Further, primary and secondary non-concurrent nodes may be identified and a signal sent to the secondary node for it to communicate, at a different priority than the primary node, during at least one of a plurality of non-concurrent time slots the primary node is communicating during.

Abstract: Reuse of transmission resources is discussed in which a transmitting node may reuse an entire remaining overlapping basic service set (OBSS) transmission opportunity (TXOP) instead of being limited to reuse based on a per-frame basis. The node may reuse the remaining TXOP if the expected caused interference to other nodes using the resources is below a predetermined threshold. Spatial reuse information may be classified into different mode based on the manner in which the spatial reuse information is obtained by the transmitting node. The manner in which the expected caused interference may be determine may be associated with the particular spatial reuse mode.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be an AP that requests a plurality of STAs to jointly enable and disable an MRP based on at least one of that each STA of the STAs has uplink traffic with the AP or that each STA of a subset of the STAs has a hidden node. The AP receives, from the STAs, information indicating a communication metric while jointly enabling or disabling the MRP. The AP determines, based on the received information indicating the communication metric, whether the joint enablement of the medium reserving procedure improves communication for the plurality of STAs. The AP requests the STAs to jointly enable the medium reserving procedure for subsequent communication when the joint enablement of the medium reserving procedure improves communication for the plurality of STAs.
