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.
Claims26
1-27. (canceled)
An apparatus, comprising:
- a processor;
- a memory;
- and
- an access point (AP) comprising logic, at least a portion of which is in hardware, the logic to:
- transmit a multi-channel request-to-send (MRTS) reserving multiple channels sensed as being free by the AP, the MRTS addressed to a plurality of stations (STAs);
- and
- process a multi-channel clear-to-send (MCTS) received from a STA comprised among the plurality of STAs, the MCTS to comprise free channel information for a determination of one or more channels to be utilized for one or more multi-user multiple-input multiple-output (MU-MIMO) transmissions of the AP, the MCTS to identify one or more channels sensed as free by the STA, the one or more channels to comprise a subset of the multiple channels sensed as being free by the AP.
4 more elements
At least one non-transitory computer-readable storage medium comprising a set of instructions that, in response to being executed at an access point (AP), cause the AP to:
- transmit a multi-channel request-to-send (MRTS) reserving multiple channels sensed as being free by the AP, the MRTS addressed to a plurality of stations (STAs);
- and
- process a multi-channel clear-to-send (MCTS) received from a STA comprised among the plurality of STAs, the MCTS to comprise free channel information for a determination of one or more channels to be utilized for one or more multiple-input multiple-output (MU-MIMO) transmissions of the AP, the MCTS to identify one or more channels sensed as free by the STA, the one or more channels to comprise a subset of the multiple channels sensed as being free by the AP.
A method, comprising:
- transmitting, from an access point (AP), a multi-channel request-to-send (MRTS) reserving multiple channels sensed as being free by the AP, the MRTS addressed to a plurality of stations (STAs);
- and
- processing a multi-channel clear-to-send (MCTS) received from a STA comprised among the plurality of STAs, the MCTS to comprise free channel information for a determination of one or more channels to be utilized for one or more multiple-input multiple-output (MU-MIMO) transmissions of the AP, the MCTS to identify one or more channels sensed as free by the STA, the one or more channels to comprise a subset of the multiple channels sensed as being free by the AP.
