Abstract

A method for configuring at least one component carrier (CC) for a physical downlink shared channel (PDSCH). The method includes receiving a CC configuration using a signaling protocol, wherein the CC is assigned using a semi-static configuration. Also included is a user equipment (UE) comprising a processor configured to receive a CC configuration for at least one CC for a PDSCH using a signaling protocol, wherein the CC is assigned using a semi-static configuration. Also included is an access node comprising a processor configured to transmit a CC configuration for at least one CC for a PDSCH using a signaling protocol, wherein the CC is assigned using a semi-static configuration.

Claims (46)

1. A method for configuring a component carrier (CC) in a wireless communication network, the method comprising:

receiving, by a user equipment (UE) in the wireless communication network, a CC configuration for a physical downlink shared channel (PDSCH), using a signaling protocol, wherein at least one CC is assigned for the PDSCH using a semi-static configuration; and

receiving, by the user equipment, a CC configuration for a Physical Downlink Control Channel (PDCCH) associated with the PDSCH, using the signaling protocol,

wherein the CC configuration for the PDSCH is based on a traffic load for the UE, and

wherein a number of assigned CCs for the PDSCH is increased to support an increase in a transmission data rate for the UE.

2. The method of claim 1 , wherein receiving the CC configuration for the PDSCH comprises receiving a CC configuration for using maximum allowed CCs for the PDSCH.

3. The method of claim 1 , wherein the PDCCH is configured using a separate coding scheme, and wherein the same CCs are assigned to the PDSCH and the associated PDCCH using the same signaling parameter.

4. The method of claim 1 , wherein the PDCCH is configured using a joint coding scheme, and wherein different CCs are assigned to the PDSCH and the associated PDCCH, using a bitmap.

5. The method of claim 1 , wherein the signaling protocol comprises a Radio Resource Control (RRC) protocol or Media Access Control (MAC) signaling.

6. The method of claim 1 , further comprising:

transmitting, by the user equipment, a CC configuration for at least one CC for an uplink (UL) using a signaling protocol, wherein the at least one CC for the UL is assigned using the semi-static configuration.

7. The method of claim 1 , further comprising:

transmitting, by the user equipment, a CC configuration for at least one CC for a Physical Uplink Control Channel (PUCCH) associated with the UL using the signaling protocol, wherein the at least one CC for the PUCCH is assigned using the semi-static configuration.

8. A method for configuring a component carrier (CC) in a wireless communication network, the method comprising:

transmitting, by an access node in the wireless communication network, a CC configuration for a physical downlink shared channel (PDSCH), using a signaling protocol, wherein at least one CC is assigned for the PDSCH using a semi-static configuration; and

transmitting, by the access node, a CC configuration for a Physical Downlink Control Channel (PDCCH) associated with the PDSCH, using the signaling protocol,

wherein the CC configuration for the PDSCH is based on a traffic load for a user equipment (UE) in the wireless communication network, and

wherein a number of assigned CCs for the PDSCH is increased to support an increase in a transmission data rate for the UE.

9. The method of claim 8 , further comprising:

receiving a CC configuration for at least one CC for an uplink (UL) using a signaling protocol, wherein the at least one CC for the UL is assigned using the semi-static configuration.

10. A user equipment (UE) for use in a wireless communication network, the user equipment comprising:

a processor configured to receive a component carrier (CC) configuration for a physical downlink shared channel (PDSCH), using a signaling protocol, wherein at least one CC is assigned for the PDSCH using a semi-static configuration,

wherein the processor is further configured to receive a CC configuration for a Physical Downlink Control Channel (PDCCH) associated with the PDSCH, using the signaling protocol,

wherein the CC configuration for the PDSCH is based on a traffic load for the UE, and

wherein a number of assigned CCs for the PDSCH is increased to support an increase in a transmission data rate for the UE.

11. The UE of claim 10 , wherein the CC configuration for the PDSCH is configured to use maximum allowed CCs for the PDSCH.

12. The UE of claim 10 , wherein the at least one CC assigned for the PDSCH is synchronized with an access node in the wireless communication network, using a start time.

13. The UE of claim 10 , wherein the processor is further configured to transmit a CC configuration for at least one CC for an uplink (UL) using a signaling protocol, wherein the at least one CC for the UL is assigned using the semi-static configuration.

14. The UE of claim 10 , wherein the processor is further configured to transmit a CC configuration for at least one CC for a Physical Uplink Control Channel (PUCCH) associated with the UL using the signaling protocol, wherein the at least one CC for the PUCCH is assigned using the semi-static configuration.

15. An access node for use in a wireless communication network, the access node comprising:

a processor configured to transmit a component carrier (CC) configuration for a physical downlink shared channel (PDSCH), using a signaling protocol, wherein at least one CC is assigned for the PDSCH using a semi-static configuration; and

wherein the processor is further configured to transmit a CC configuration for a Physical Downlink Control Channel (PDCCH) associated with the PDSCH, using the signaling protocol,

wherein the CC configuration for the PDSCH is based on a traffic load for a user equipment (UE) in the wireless communication network, and

wherein a number of assigned CCs for the PDSCH is increased to support an increase in a transmission data rate for the UE.

16. The access node of claim 15 , wherein the processor is further configured to receive a CC configuration for at least one CC for an uplink (UL) using a signaling protocol, wherein the at least one CC for the UL is assigned using the semi-static configuration.

17. The access node of claim 15 , wherein the processor is further configured to receive a CC configuration for at least one CC for a Physical Uplink Control Channel (PUCCH) associated with the UL using the signaling protocol, wherein the at least one CC for the PUCCH is assigned using the semi-static configuration.

18. A non-transitory computer readable medium storing instructions which are configured to cause a user equipment (UE) device to execute a method comprising the operations of:

receiving a CC configuration for a physical downlink shared channel (PDSCH), using a signaling protocol, wherein at least one CC is assigned for the PDSCH using a semi-static configuration; and
