Method and system for signalling resource allocation information in an asymmetric multicarrier communication network
First Claim
1. A method of signaling resource allocation information in a multicarrier communication system, the method comprising:
- allocating resources in a downlink allocation interval for a secondary downlink carrier and an uplink allocation interval for a secondary uplink carrier, wherein the downlink allocation interval is included in a part of a first subframe and a part of a second subframe on the secondary downlink carrier and starts at a first predefined offset after a start time of a subframe on a primary downlink carrier, wherein the uplink allocation interval is included in a part of a third subframe and a part of a fourth subframe on the secondary uplink carrier and starts at a second predefined offset after the start time of the subframe on the primary downlink carrier, wherein a duration of the downlink allocation interval is equal to a duration of one subframe, and wherein a duration of the uplink allocation interval is equal to the duration of one subframe; and
transmitting resource allocation information about the allocated resources in a control region included in the subframe on the primary downlink carrier to a mobile station, wherein the resource allocation information includes information indicating a start time for the downlink allocation interval for the secondary downlink carrier and information indicating a start time for the uplink allocation interval for the secondary uplink carrier,wherein each of frequencies of the secondary downlink carrier and the secondary uplink carrier is higher than a frequency of the primary downlink carrier.

Abstract
A method and system signal resource allocation information in an asymmetric multicarrier communication network. A MS communicates with a BS using asymmetric carriers consisting of at least one low frequency carrier (e.g., primary carriers) in a cellular band and at least one high frequency carrier (e.g., secondary carriers) in a millimeter Wave band. In one embodiment, the BS allocates resources for one or more transmit time intervals in at least one of DL allocation interval of a secondary DL carrier and UL allocation interval of a secondary UL carrier for the MS, where the DL allocation interval spans one or more subframes of the secondary DL carrier and the UL allocation interval spans one or more subframes of the secondary UL carrier. The BS then transmits information regarding the allocated resources to the MS in a Packet Data Control Channel region of a subframe of the primary DL carrier.
