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: Methods and apparatus for determining backoff values when transitioning between single-user (SU) and multi-user (MU) modes are provided. A station (STA) transitions from a Single-User (SU) mode, in which a first set of parameters is used to attempt to access a medium, to a Multi-User (MU) mode, in which a second set of parameters is used to attempt to access the medium. The STA determines, upon transitioning back from the MU mode to the SU mode, one or more values to use for setting corresponding one or more of a set of backoff counters. The STA attempts, after setting the one or more backoff counters, to access the medium for one or more SU transmissions based on the set of backoff counters.
