摘要
Wireless communications systems and methods related to performing random backoff over multiple spatial dimensions in spatial listen-before-talk (LBT) procedures are provided. A first wireless communication device determines a first backoff counter for contending for a transmission opportunity (TXOP) in a communication medium over a first spatial subspace. The first wireless communication device detects a transmission in the TXOP within the first spatial subspace. The first wireless communication device determines a second backoff counter for contending for the TXOP over a second spatial subspace that is different from the first spatial subspace based on the detecting. The second spatial subspace is part of the first spatial subspace and the detected transmission is in a different spatial subspace than the second spatial subspace.
