1. An apparatus, comprisinga first device for operating in a wireless communication network, the first device including a processor, a memory, and at least one radio, the at least one radio to:
- transmit a multi-channel request-to-send (MRTS) to reserve multiple channels to a second device in the wireless communications network, a first indication in the MRTS of which of multiple channels were sensed by the first device as being free;
receive a first multi-channel clear-to-send (MCTS) from the second device, a second indication in the MCTS of which of the multiple channels indicated by the first indication were sensed by the second device as being free; and
transmit a message to the second device using one or more of the channels indicated by the second indication.

Abstract
In various embodiments, a multi-channel request-to-send and a multi-channel clear-to-send may be used in a wireless communications network to assure that a subsequent multi-channel communications exchange between two devices takes place only over channels that are sensed by both devices as being free.
