Abstract
Control information may be used to schedule communications between a wireless device and a base station. The wireless device may monitor control channels associated with one or more cells to receive the control information.
Claims30
A method comprising:
- receiving, by a wireless device and via a first search space of a primary cell, first downlink control information (DCI) comprising at least one first resource assignment for the primary cell;
- receiving a medium access control (MAC) control element (CE) indicating activation of a secondary cell;
- and
- based on the receiving the MAC CE,
- activating cross-carrier scheduling of the primary cell by the secondary cell;
- and
- receiving, via a second search space of the secondary cell, second DCI comprising at least one second resource assignment for the primary cell.
4 more elements
A method comprising:
- receiving, by a wireless device and via a first search space of a primary cell, first downlink control information (DCI) comprising at least one first resource assignment for the primary cell, wherein the receiving the first DCI is based on monitoring for a first DCI format;
- receiving a command indicating activation of cross-carrier scheduling of the primary cell via a secondary cell;
- and
- based on the receiving the command, receiving, via a second search space of the secondary cell, second DCI comprising at least one second resource assignment for the primary cell, wherein the receiving the second DCI is based on monitoring for a second DCI format.
1 more element
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, via a first search space of a primary cell, first downlink control information (DCI) comprising at least one first resource assignment for the primary cell;
- receive a medium access control (MAC) control element (CE) indicating activation of a secondary cell;
- and
- based on the receiving the MAC CE,
- activate cross-carrier scheduling of the primary cell by the secondary cell;
- and
- receive, via a second search space of the secondary cell, second DCI comprising at least one second resource assignment for the primary cell.

- receive a command indicating activation of cross-carrier scheduling of the primary cell via a secondary cell;
- and
- based on the receiving the command, receive, via a second search space of the secondary cell, second DCI comprising at least one second resource assignment for the primary cell, wherein the receiving the second DCI is based on monitoring for a second DCI format.
