1. A method comprising:
- receiving, by a wireless device, configuration parameters of a plurality of cells, wherein the plurality of cells are grouped into a plurality of cell groups comprising;
a primary cell group comprising a primary cell; and
a secondary cell group comprising a secondary cell configured with uplink scheduling request (SR) resources;
receiving an activation command indicating activation of the secondary cell; and
determining that the secondary cell has an invalid uplink SR resource based on;
at least one uplink SR pending in a time interval;
the uplink SR resources being configured in the time interval; and
a time alignment timer, associated with the secondary cell group, not running in the time interval.

Abstract
Methods, apparatuses, and systems are described for wireless communications. Cells may be grouped into a plurality of cell groups. A wireless device may determine that a secondary cell has an invalid scheduling request (SR) resource based on various conditions. The wireless device may transmit a preamble via a primary cell if the secondary cell has an invalid SR resource.

27. A system comprising:
-
a base station comprising; one or more processors; and memory storing instructions that, when executed by the one or more processors of the base station, cause the base station to; transmit configuration parameters of a plurality of cells, wherein the plurality of cells are grouped into a plurality of cell groups comprising; a primary cell group comprising a primary cell; and a secondary cell group comprising a secondary cell configured with uplink scheduling request (SR) resources; and transmit an activation command indicating activation of the secondary cell; and a wireless device comprising; one or more processors; and memory storing instructions that, when executed by the one or more processors of the wireless device, cause the wireless device to; determine that the secondary cell has an invalid uplink SR resource based on; at least one uplink SR pending in a time interval; the uplink SR resources being configured in the time interval; and a time alignment timer, associated with the secondary cell group, not running in the time interval. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
