Abstract

A system and method for configuring a component carrier is presented. A component carrier assignment message is received. The component carrier assignment message may be configured to identify the component carrier and include at least one of, at least one of a downlink carrier frequency, a carrier frequency of a paired uplink carrier, a bandwidth of the component carrier, and a bandwidth of the paired uplink carrier, an indication of whether the component carrier is a control channel monitoring component carrier configured to signal data channel assignment information for the component carrier, and a logical index of the component carrier. The component carrier assignment message may then be used to configure the component carrier on a user equipment (UE).

First claim

The invention claimed is:

1. A method, comprising:
receiving a component carrier assignment message via a first component carrier different from a second component carrier and a third component carrier, the first component carrier a control channel monitoring component carrier, the component carrier assignment message identifying the second component carrier and the third component carrier and including:
a physical cell identity (PCI) of the second component carrier;
a PCI of the third component carrier;
an indication that the second component carrier is a control channel monitoring component carrier configured to signal data channel assignment information associated with the second component carrier;
an indication that the third component carrier is a not control channel monitoring component carrier and an indication that a control channel of the first component carrier is configured to signal data channel assignment information for the third component carrier;
an antenna configuration for the second component carrier;
an antenna configuration for the third component carrier; and
using the component carrier assignment message to configure the second component carrier and the third component carrier on a user equipment (UE).

2. The method of claim 1 , wherein the control channel is a physical downlink control channel (PDCCH).

3. The method of claim 1 , wherein the first component carrier comprises a cell.

4. The method of claim 1 , wherein the component carrier assignment message is received using dedicated signaling.

5. A method, comprising: receiving a component carrier assignment message via a first component carrier different from a second component carrier and a third component carrier, the first component carrier a control channel monitoring component carrier, the component carrier assignment message identifying the second component carrier and the third component carrier and including a physical cell identity (PCI) of the second component carrier, a PCI of the third component carrier, an indication that the second component carrier is a control channel monitoring component carrier configured to signal data channel assignment information for the second component carrier, and an indication that the third component carrier is a not control channel monitoring component carrier and an indication that a control channel of the first component carrier is configured to signal data channel assignment information for the third component carrier; and
using the component carrier assignment message to configure the second component carrier and the third component carrier on a user equipment (UE).

6. The method of claim 5 , wherein the component carrier assignment message includes:
system information block type 1 data including at least one of a physical cell identity (PCI), cell global identity (CGI), and closed subscriber group (CSG) information,
system information block type 2 data identifying a radio resource configuration,
at least one of a physical component carrier index and a mapped logical component carrier index of the component carrier, and
an antenna configuration for the component carrier.

7. The method of claim 5 , wherein the component carrier assignment message is received using dedicated signaling.

8. The method of claim 5 , wherein the first component carrier comprises a cell.

9. A method, comprising:
transmitting, by a first component carrier different from a second component carrier and a third component carrier, a component carrier assignment message, the component carrier assignment message identifying the second component carrier and including a physical cell identity (PCI) of the second component carrier, a PCI of the third component carrier, an indication that the second component carrier is a control channel monitoring component carrier configured to signal data channel assignment information for the second component carrier, and an indication that the third component carrier is a not control channel monitoring component carrier and an indication that a control channel of the first component carrier is configured to signal data channel assignment information for the third component carrier; and
communicating with user equipment using the second component carrier and the third component carrier.

10. The method of claim 9 , wherein the component carrier assignment message includes:
system information block type 1 data including at least one of a physical cell identity (PCI), cell global identity (CGI), and closed subscriber group (CSG) information,
system information block type 2 data identifying a radio resource configuration,
an indication of whether the component carrier is a physical downlink control channel (PDCCH) monitoring component carrier,
at least one of a physical component carrier index and a mapped logical component carrier index of the first component carrier, and
an antenna configuration for the first component carrier.

11. The method of claim 9 , wherein the component carrier assignment message is transmitted using dedicated signaling.

12. The method of claim 9 , wherein the component carrier comprises a cell.

13. A user equipment, comprising:
a processor, the processor being configured to:
receive a component carrier assignment message from a first component carrier different from a second component carrier, the component carrier assignment message identifying the second component carrier and a third component carrier and including a physical cell identity (PCI) of the second component carrier, a PCI of the third component carrier, an indication that the second component carrier is a control channel monitoring component carrier configured to signal data channel assignment information for the second component carrier, and an indication that the third component carrier is a not control channel monitoring component carrier and an indication that a control channel of the first component carrier is configured to signal data channel assignment information for the third component carrier; and
use the component carrier assignment message to configure the second component carrier and the third component carrier on a user equipment (UE).

14. The user equipment of claim 13 , wherein the component carrier assignment message includes:
system information block type 1 data including at least one of a physical cell identity (PCI), cell global identity (CGI), and closed subscriber group (CSG) information,
system information block type 2 data identifying a radio resource configuration,
at least one of a physical component carrier index and a mapped logical component carrier index of the first component carrier, and
an antenna configuration for the first component carrier.

15. A base station, comprising:
one or more processors configured to:
transmit, by a first component carrier different from a second component carrier and a third component carrier, a component carrier assignment message, the component carrier assignment message identifying the second component carrier and including a physical cell identity (PCI) of the second component carrier, a PCI of the third component carrier, an indication that the second component carrier is a control channel monitoring component carrier configured to signal data channel assignment information for the second component carrier, and an indication that the third component carrier is a not control channel monitoring component carrier and an indication that a control channel of the first component carrier is configured to signal data channel assignment information for the third component carrier; and
communicate with user equipment
