1. A method comprising:
- receiving, by a wireless device, one or more radio resource control (RRC) messages comprising configuration parameters for a first licensed assisted access (LAA) cell and a second LAA cell;
transmitting an uplink transmission during a subframe via the second LAA cell; and
based on the uplink transmission during the subframe via the second LAA cell, skipping monitoring of a physical downlink control channel (PDCCH) during the subframe for the first LAA cell.

Abstract
A wireless device receives one or more radio resource control (RRC) messages comprising configuration parameters for a first licensed assisted access (LAA) cell and a second LAA cell. The wireless device selectively monitors, in a first subframe, a downlink physical control channel (PDCCH) on a first LAA cell, depending on whether there is an uplink transmission in the first subframe on the second LAA cell.

10. A wireless device comprising:
-
one or more processors; and memory storing instructions that, when executed by the one or more processors, cause the wireless device to; receive one or more radio resource control (RRC) messages comprising configuration parameters for a first licensed assisted access (LAA) cell and a second LAA cell; transmit an uplink transmission during a subframe via the second LAA cell; and based on the uplink transmission during the subframe via the second LAA cell, skip monitoring of a physical downlink control channel (PDCCH) during the subframe for a first LAA cell. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 20)
