TECHNIQUES FOR NON-SIMULTANEOUS TRANSMIT AND RECEIVE STATION OPERATION DURING SYNCHRONIZATION PROCEDURES

Abstract:

This disclosure provides methods, devices and systems for non-simultaneous transmit and receive (STR) station (STA) transmissions using multiple links. In one aspect, a medium synchronization delay timer associated with a second link of the non-STR STA can be initiated in response to completing transmission of the data on the first link to delay triggering of a clear channel assessment (CCA) associated with the second link. Data can be transmitted on the second link in response to expiration of the medium synchronization delay timer. In another aspect, an energy detect (ED) threshold level on a second link may be decreased from a first ED threshold level to a second ED threshold level after transmitting the data on the first link. In a further aspect, a block acknowledgment (BA) frame including a network allocation vector (NAV) synchronization of a second access point may be transmitted to the first link of the station.
