Claim of US Patent No. 10,368,365

1. A method for wireless communication, comprising:identifying a first transient period between a transmit OFF power and transmit ON power for a wireless transmitter, the first transient period identified for a first transmission time interval (TTI) for an uplink transmission of the wireless transmitter, the first TTI having a first duration that is shorter than a threshold duration;
identifying a second transient period between the transmit ON power and transmit OFF power for the wireless transmitter;
identifying a transmission bandwidth for the uplink transmission, wherein one or more of the first transient period or the second transient period are identified based at least in part on the transmission bandwidth for the uplink transmission, and wherein one or more of the first transient period or the second transient period has a longer duration for narrowband transmission bandwidths than for wideband transmission bandwidths:
applying the first transient period as an OFF-ON mask that starts before a start of the first TTI;
applying the second transient period as an ON-OFF mask that ends after an end of the first TTI; and
transmitting the uplink transmission during the first TTI.
