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.
Claims25
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.
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.
