DCFirst Claim
1. An apparatus of an enhanced directional multi gigabit (EDMG) station (STA), the apparatus comprising:
- memory; and
processing circuitry coupled to the memory, the processing circuitry configured to;
decode a non EDMG physical layer convergence procedure (PLCP) protocol data unit (PPDU), the non-EDMG PPDU comprising a legacy header (L-Header), the L-Header comprising a field that indicates a control trailer is present, the non-EDMG PPDU further comprising a grant frame, the grant frame indicating an intent to transmit to the STA on a bonded channel an EDMG PPDU at a time indicated by a value of an allocation duration field, the control trailer indicating the bonded channel, wherein the non-EDMG PPDU is received from a peer STA; and
decode the EDMG PPDU, wherein the EDMG PPDU is received on the bonded channel from the peer STA.

Abstract
Devices and methods of limiting wideband STA communication are generally described. The STA receives, over a primary channel, a wakeup frame containing an indication of a SP or CBAP to acquire a wideband TXOP over a wide bandwidth channel including the primary channel and a secondary channel and a control trailer having an indication of the wide bandwidth channel. Prior to the SP/CBAP, the STA opens reception from the primary channel to the wide bandwidth channel. The STA then communicates with another STA over the wide bandwidth channel and subsequently reduces reception from the wide bandwidth channel to the primary channel. The wakeup frame originates from an AP/PCP or the other STA, and contains fields indicating the wakeup frame length and SP or a sensing time length prior to the CBAP.
