1. A method comprising:
- receiving, by a wireless device, one or more listen-before-talk (LBT) parameters for a plurality of licensed assisted access (LAA) cells;
receiving uplink grants for uplink transmissions, each having a same starting position, via the plurality of LAA cells;
performing, for a first LAA cell of the plurality of LAA cells, a first type of LBT procedure associated with a first duration;
performing, for a second LAA cell of the plurality of LAA cells, a second type of LBT procedure associated with a second duration shorter than the first duration, wherein the second LAA cell is different from the first LAA cell;
based on the first type of LBT procedure indicating a clear channel for the first LAA cell, transmitting a first transport block via the first LAA cell; and
based on the first type of LBT procedure indicating a clear channel for the first LAA cell and the second type of LBT procedure indicating a clear channel for the second LAA cell, transmitting a second transport block via the second LAA cell.

Abstract
Methods, apparatuses, and systems are described for wireless communications. A wireless device may perform listen before talk (LBT) procedures for licensed assisted access (LAA) cells. The LBT procedures may use different monitoring periods. The wireless device may transmit transport blocks (TBs) via the LAA cells.
