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.

Claims (69)

1 . 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.

2 . The method of claim 1 , wherein the HARQ information is transmitted by the base station to the wireless device and comprises:

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the primary cell; and

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the secondary cell.

3 . The method of claim 1 , wherein uplink channel resources of the secondary cell are not configured with physical random access (PRACH) resources.

4 . The method of claim 1 , wherein uplink channel resources of the secondary cell are not configured with physical uplink control channel (PUCCH) resources.

5 . The method of claim 1 , wherein a carrier of the secondary cell supports fewer transmission modes than a carrier of the primary cell.

6 . The method of claim 1 , further comprising sending synchronization signals via a carrier of the primary cell and via a carrier of the secondary cell, wherein synchronization signals on the carrier of the primary cell are configured to avoid overlap with synchronization signals on the carrier of the secondary cell.

7 . 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.

8 . The one or more non-transitory, computer-readable media of claim 7 , wherein the HARQ information is transmitted by the base station to the wireless device and comprises:

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the primary cell; and

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the secondary cell.

9 . The one or more non-transitory, computer-readable media of claim 7 , wherein uplink channel resources of the secondary cell are not configured with physical random access (PRACH) resources.

10 . The one or more non-transitory, computer-readable media of claim 7 , wherein uplink channel resources of the secondary cell are not configured with physical uplink control channel (PUCCH) resources.

11 . The one or more non-transitory, computer-readable media of claim 7 , wherein a carrier of the secondary cell supports fewer transmission modes than a carrier of the primary cell.

12 . The one or more non-transitory, computer-readable media of claim 7 , wherein the instructions, when executed, further configure the base station to send synchronization signals via a carrier of the primary cell and via a carrier of the secondary cell, wherein synchronization signals on the carrier of the primary cell are configured to avoid overlap with synchronization signals on the carrier of the secondary cell.

13 . 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.

14 . The base station of claim 13 , wherein the HARQ information is transmitted by the base station to the wireless device and comprises:

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the primary cell; and

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the secondary cell.

15 . The base station of claim 13 , wherein uplink channel resources of the secondary cell are not configured with physical random access (PRACH) resources.

16 . The base station of claim 13 , wherein uplink channel resources of the secondary cell are not configured with physical uplink control channel (PUCCH) resources.

17 . The base station of claim 13 , wherein a carrier of the secondary cell supports fewer transmission modes than a carrier of the primary cell.

18 . The base station of claim 13 , wherein the instructions, when executed, further configure the base station to send synchronization signals via a carrier of the primary cell and via a carrier of the secondary cell, wherein synchronization signals on the carrier of the primary cell are configured to avoid overlap with synchronization signals on the carrier of the secondary cell.

19 . 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.

20 . The system of claim 19 , wherein the HARQ information is transmitted by the base station to the wireless device and comprises:

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the primary cell; and

an acknowledgement for uplink data transmitted via an uplink channel corresponding to the secondary cell.

21 . The system of claim 19 , wherein uplink channel resources of the secondary cell are not configured with physical random access (PRACH) resources.

22 . The system of claim 19 , wherein uplink channel resources of the secondary cell are not configured with physical uplink control channel (PUCCH) resources.

23 . The system of claim 19 , wherein a carrier of the secondary cell supports fewer transmission modes than a carrier of the primary cell.

24 . The system of claim 19 , wherein the base station is configured to send synchronization signals via a carrier of the primary cell and via a carrier of the secondary cell, wherein synchronization signals on the carrier of the primary cell are configured to avoid overlap with synchronization signals on the carrier of the secondary cell.
