Abstract

A transmitter includes a bandwidth configuration unit configured to provide an increased system bandwidth corresponding to a bandwidth extension over multiple component carriers. Additionally, the transmitter also includes a transmit unit configured to employ the bandwidth extension.

Claims (39)

1 . A user equipment (UE), comprising:

a receive unit configured to receive, via Radio Resource Control (RRC) signaling, information indicative of a single carrier from a plurality of carriers that collectively form a total transmission bandwidth, and to receive a system information block (SIB) on the single carrier, each of the carriers having a bandwidth of 20 MHz, a bandwidth of the SIB being contained entirely within the single carrier; and

a transmit unit configured to transmit all physical uplink control channel (PUCCH) control information over the single carrier.

2 . A method, comprising:

receiving, by a user equipment (UE) via Radio Resource Control (RRC) signaling, information indicative of a single carrier from a plurality of carriers that collectively form a total transmission bandwidth, each of the carriers having a bandwidth of 20 MHz;

receiving, by the UE, a system information block (SIB) on the single carrier, a bandwidth of the SIB being contained entirely within the single carrier; and

transmitting, by the UE, all physical uplink control channel (PUCCH) control information over the single carrier.

3 . The method of claim 2 , wherein the total transmission bandwidth includes common control information that occupies only one carrier or is replicated in all carriers of the plurality of carriers.

4 . The method of claim 2 , wherein the total transmission bandwidth includes dedicated control information that occupies at least one carrier.

5 . The method of claim 2 , wherein the total transmission bandwidth includes multiple separate contiguous carriers.

6 . The method of claim 2 , wherein the control information in the total transmission bandwidth includes common control information that occupies only one carrier.

7 . The method of claim 2 , wherein the control information in the total transmission bandwidth includes dedicated control information that occupies only one carrier.

8 . The method of claim 2 , wherein the control information in the total transmission bandwidth includes common control information that occupies two carriers.

9 . The method of claim 2 , wherein the control information in the total transmission bandwidth includes dedicated control information that occupies two carriers.

10 . The method of claim 2 , wherein the control information in the total transmission bandwidth includes common control information that occupies more than two carriers.

11 . The method of claim 2 , wherein the control information in the total transmission bandwidth includes dedicated control information that occupies more than two carriers.

12 . A method, comprising:

receiving, by a user equipment (UE) via Radio Resource Control (RRC) signaling, information indicative of a single component carrier from a plurality of component carriers that collectively form a total transmission bandwidth, each of the component carriers having a bandwidth of 20 MHz;

receiving, by the UE, a system information block (SIB) on the single component carrier, a bandwidth of the SIB being contained entirely within the single component carrier; and

transmitting, by the UE, all physical uplink control channel (PUCCH) control information over the single component carrier.

13 . A user equipment configured to:

receive, via Radio Resource Control (RRC) signaling, information indicative of a single component carrier from a plurality of component carriers that collectively form a total transmission bandwidth, each of the component carriers having a bandwidth of 20 MHz;

receive a system information block (SIB) on the single component carrier, a bandwidth of the SIB being contained entirely within the single component carrier; and

transmit all physical uplink control channel (PUCCH) control information over the single component carrier.

14 . The user equipment of claim 13 , wherein the total transmission bandwidth jointly aggregates multiple contiguous component carriers into a single carrier of larger bandwidth.

15 . The user equipment of claim 13 , wherein the total transmission bandwidth includes multiple separate non-contiguous component carriers.

16 . The user equipment of claim 13 , wherein the total transmission bandwidth includes common control information that occupies only one component carrier or is replicated in all component carriers.

17 . The user equipment of claim 13 , wherein the total transmission bandwidth includes dedicated control information that occupies at least one component carrier.

18 . The user equipment of claim 13 , wherein the total transmission bandwidth includes multiple separate contiguous component carriers.

19 . The user equipment of claim 13 , wherein the control information in the total transmission bandwidth includes common control information that occupies only one component carrier.

20 . The user equipment of claim 13 , wherein the control information in the total transmission bandwidth includes dedicated control information that occupies only one component carrier.

21 . The user equipment of claim 13 , wherein the control information in the total transmission bandwidth includes common control information that occupies two component carriers.

22 . The user equipment of claim 13 , wherein the control information in the total transmission bandwidth includes dedicated control information that occupies two component carriers.

23 . The user equipment of claim 13 , wherein the control information in the total transmission bandwidth includes common control information that occupies more than two component carriers.

24 . The user equipment of claim 13 , wherein the control information in the total transmission bandwidth includes dedicated control information that occupies more than two component carriers.

25 . A user equipment configured to:

receive, via Radio Resource Control (RRC) signaling, information indicative of a single carrier from a plurality of carriers that collectively form a total transmission bandwidth, each of the carriers having a bandwidth of 20 MHz;

receive a system information block (SIB) on the single carrier, a bandwidth of the SIB being contained entirely within the single carrier; and

transmit all physical uplink control channel (PUCCH) control information over the single carrier.
