Downlink grants in a multicarrier wireless communication system

摘要

Aspects describe communicating grant information in a multicarrier wireless communication system. The grant information can be transmitted to mobile devices that have single carrier capability and/or mobile devices that have multicarrier capability. Grant information can be sent in a legacy control region and/or a non-legacy control region.

主权项

1. A method for transmitting grants in a multicarrier wireless communications environment, comprising:
determining, by a base station, a grant information to a user device, wherein the grant information assigns resources for a carrier in a first frequency range; selecting, by the base station, a control region on a carrier in a second frequency range in which to insert the grant information as a function of user device capabilities; inserting the grant information in the selected control region; and transmitting the grant information in the selected control region to the user device, wherein the control region is a legacy control region or a non-legacy control region, wherein the legacy control region is located on control resources monitored by mobile devices configured for single carrier systems, and wherein the non-legacy control region excludes the control resources monitored by mobile devices configured for single carrier systems.
