Method and apparatus for monitoring downlink channels of a plurality of cells and receiving data over a downlink channel
A method and apparatus are disclosed. The apparatus comprises a wireless transceiver and a processor. The apparatus performs wireless communications with a primary cell, receives a message via a shared channel of the primary cell, wherein the received message includes information identifying a plurality of non-primary cells, monitors downlink channels of the identified plurality of non-primary cells based on the received message, and receives data over a downlink channel of at least one of the identified plurality of non-primary cells based on the monitored downlink channels.
1. A wireless transmit/receive unit (WTRU) comprising:
a wireless transceiver; and
a processor,
wherein the wireless transceiver and the processor cause the WTRU to:
perform wireless communications with a primary cell associated with a base station;
receive a message from the base station via a shared channel of the primary cell, wherein the received message includes information identifying at least one non-primary cell associated with the base station;
monitor downlink channels of the identified at least one non-primary cell based on the received message from the base station; and
receive data over a downlink channel of at least one of the identified at least one non-primary cell based on the monitored downlink channels.
2. The WTRU of claim 1 , wherein the received message is received over a shared downlink channel via the primary cell, and wherein the information identifying the at least one plurality of non-primary cell is control information.
3. The WTRU of claim 2 , wherein the shared downlink channel is one of a plurality of shared downlink channels of the primary cell.
4. The WTRU of claim 2 , wherein the processor further causes the WTRU to read the control information.
5. The WTRU of claim 1 , wherein the received message further includes information identifying a plurality of shared downlink data channels of the at least one non-primary cell.
6. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
performing wireless communications with a primary cell associated with a base station;
receiving a message from the base station via a shared channel of the primary cell, wherein the received message includes information identifying at least one non-primary cell associated with the base station;
monitoring downlink channels of the identified at least one non-primary cell based on the received message from the base station; and
receiving data over a downlink channel of at least one of the identified at least one non-primary cell based on the monitored downlink channels.
7. The method of claim 6 , wherein the received message is received over a shared downlink channel via the primary cell, and wherein the information identifying the at least one plurality of non-primary cell is control information.
8. The method of claim 7 , wherein the shared downlink channel is one of a plurality of shared downlink channels of the primary cell.
9. The method of claim 7 , further comprising reading the control information.
10. The method of claim 6 , wherein the received message further includes information identifying a plurality of shared downlink data channels of the at least one non-primary cell.
