First Claim
Patent Images
1. A method of wireless communication, comprising:
- receiving extended bandwidth information indicating availability of an extended bandwidth, the extended bandwidth including a base carrier and an extension carrier within a legacy guard band of the base carrier; and
receiving data on a downlink in the extension carrier within the legacy guard band of the base carrier based on the extended bandwidth information, wherein the downlink is operated within a legacy composite bandwidth, wherein the extension carrier is operated within the extended bandwidth, wherein the extended bandwidth is within the legacy composite bandwidth, and wherein the extended bandwidth comprises a base bandwidth of the base carrier, an upper extended bandwidth in an upper legacy guard band of the base carrier, and a lower extended bandwidth in a lower legacy guard band of the base carrier; and
receiving control information on the downlink in a control channel that extends (a) across the extended bandwidth into the extension carrier in a first set of subframes and (b) across and within the base bandwidth of the base carrier in a second set of subframes.
