Abstract
A base station may transmit, to a wireless device, configuration parameters of a downlink control channel. The configuration parameters may indicate features such as a time interval in which the downlink control channel is configured, and a starting symbol, and the base station may use the downlink control channel for transmitting packet scheduling information. The base station may configure a primary cell and a secondary cell, which a wireless device may use to communicate with the base station. A downlink channel of the primary cell may comprise acknowledgement for information transmitted via the primary cell as well as for information transmitted via the secondary cell.
Claims24
A method comprising:
- configuring, by a base station, a primary cell and a secondary cell;
- and
- communicating, by the base station with a wireless device, via the primary cell and the secondary cell,
- wherein the primary cell comprises:
- scheduling information for both the primary cell and the secondary cell;
- and
- a downlink channel comprising hybrid automatic request (HARQ) information comprising:
- an acknowledgement for information transmitted via the primary cell;
- and
- an acknowledgement for information transmitted via the secondary cell, and
- wherein a channel with HARQ feedback resources is absent from a downlink channel of the secondary cell.
One or more non-transitory, computer-readable media storing instructions that, when executed, configure a base station to:
- configure a primary cell and a secondary cell;
- and
- communicate with a wireless device via the primary cell and the secondary cell,
- wherein the primary cell comprises:
- scheduling information for both the primary cell and the secondary cell;
- and
- a downlink channel comprising hybrid automatic request (HARQ) information comprising:
- an acknowledgement for information transmitted via the primary cell;
- and
- an acknowledgement for information transmitted via the secondary cell, and
- wherein a channel with HARQ feedback resources is absent from a downlink channel of the secondary cell.
A base station comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, configure the base station to:
- configure a primary cell and a secondary cell;
- and
- communicate with a wireless device via the primary cell and the secondary cell,
- wherein the primary cell comprises:
- scheduling information for both the primary cell and the secondary cell;
- and
- a downlink channel comprising hybrid automatic request (HARQ) information comprising:
- an acknowledgement for information transmitted via the primary cell;
- and
- an acknowledgement for information transmitted via the secondary cell, and
- wherein a channel with HARQ feedback resources is absent from a downlink channel of the secondary cell.
A system comprising:
- a wireless device and a base station,
- wherein the base station is configured to:
- configure a primary cell and a secondary cell;
- and
- communicate with the wireless device via the primary cell and the secondary cell,
- wherein the primary cell comprises:
- scheduling information for both the primary cell and the secondary cell;
- and
- a downlink channel comprising hybrid automatic request (HARQ) information comprising:
- an acknowledgement for information transmitted via the primary cell;
- and
- an acknowledgement for information transmitted via the secondary cell, and
- wherein a channel with HARQ feedback resources is absent from a downlink channel of the secondary cell, and
- wherein the wireless device is configured to communicate with the base station via the primary cell and the secondary cell.
