1. A method comprising:
- obtaining data to be wirelessly transmitted in a frame in an unlicensed spectrum;
determining whether an entire subframe of the frame is required to completely communicate the data;
responsive to determining that the data does not require the entire subframe, generating a burst transmission so as to minimize a time period of the subframe used to communicate the data; and
transmitting the burst transmission and a parameter indicating a duration of the burst transmission.

Abstract
Modifications to frame/subframe structure are presented herein so that a wirelessdevice can transmit its data within a fraction of a subframe. The device obtains data to be transmitted in an unlicensed spectrum and determines whether an entire subframe is required to completely communicate the data. If the data is small enough to not require the entire subframe, then the device generates a burst transmission to minimize the time period of the subframe used to communicate the data. The device transmits the burst transmission and a parameter indicating the duration of the burst transmission.

10. An apparatus comprising:
-
a transmitter configured to transmit signals in an unlicensed spectrum; a modem configured to modulate signals for transmission in a frame; a processor configured to; obtain data to be wirelessly transmitted by the transmitter; determine whether an entire subframe of the frame is required to completely communicate the data; responsive to determining that the data does not require the entire subframe, generate a burst transmission so as to minimize a time period of the subframe used to communicate the data; and cause the transmitter to transmit the burst transmission and a parameter indicating a duration of the burst transmission. - View Dependent Claims (11, 12, 13, 14, 15)
