Abstract: Methods, systems, and devices for wireless communication are described. A first device in a synchronous network performs a first clear channel assessment (CCA) procedure on a channel; identifies the channel as being available based at least in part on the first CCA procedure; and transmits a packet on the channel immediately following the completion of the first CCA procedure. A second device performs a CCA procedure on the channel using the same count-down duration if the first and second devices are associated with the same first operator. If the first and second devices are associated with different operators, the second device performs a second CCA procedure on the channel having a different count-down duration than the count-down duration of the first CCA procedure.

Abstract: The apparatus sends a request from a medium access control (MAC) layer to at least one of a Physical (PHY) Layer or a radio frequency (RF) component using an application protocol interface (API) and receives a response message from the at least one of the PHY layer or the RF component comprising an hierarchical indication of at least one capability of the PHY layer or the RF component using the API. The apparatus may also configure the PHY layer or the RF component based on the at least one capability.
