Control signaling for wireless communication
In accordance with an example embodiment of the present invention, a method comprises allocating a control channel resource in a wireless relay transmission frame on a wireless relay link; generating a control signaling based on at least one of a resource allocation scheme, a status of the wireless relay link and a traffic condition of the wireless relay link; mapping the control signaling to the allocated control channel resource via at least one of a time-first mapping, a frequency-first mapping, and a multiplexing mapping; and transmitting the control signaling in the allocated control channel resource on the wireless relay link to at least one associated relay node.
1. A receiving device comprising:
a wireless receiver configured to receive a first signal;
a baseband processor configured to process upper layer control signaling included in the first signal, the upper layer control signaling including an indication of a location of a control resource located in LTE subframes, the control resource comprising at least one physical resource block (PRB) including at least one control channel element (CCE) designated for the receiving device;
the wireless receiver configured to receive a second signal; and
the baseband processor configured to decode the at least one CCE from the received second signal using the upper layer control signaling to recover a control channel for the receiving device.
2. The receiving device of claim 1 , wherein the receiving device is a user equipment (UE).
3. The receiving device of claim 1 , wherein the upper layer control signaling includes an indication of a starting symbol that the receiving device should monitor for the at least one CCE in the control resource located in the LTE subframes.
4. The receiving device of claim 1 , wherein the first signal and the second signal are received from an eNB.
5. The receiving device of claim 1 , wherein the at least one PRB is semi-statically allocated.
6. A method for use in a receiving device, the method comprising:
receiving a first signal;
processing upper layer control signaling included in the first signal, the upper layer control signaling including an indication of a location of a control resource located in LTE subframes, the control resource comprising at least one physical resource block (PRB) including at least one control channel element (CCE) designated for the receiving device;
receiving a second signal; and
decoding the at least one CCE from the received second signal using the upper layer control signaling to recover a control channel for the receiving device.
7. The method of claim 6 , wherein the receiving device is a user equipment (UE).
8. The method of claim 6 , wherein the upper layer control signaling includes an indication of a starting symbol that the receiving device should monitor for the at least one CCE in the control resource located in the LTE subframes.
9. The method of claim 6 , wherein the first signal and the second signal are received from an eNB.
10. The method of claim 6 , wherein the at least one PRB is semi-statically allocated.
11. A non-transitory computer readable medium that stores a set of instructions that when executed by a receiving device causes the receiving device to:
receive a first signal;
process upper layer control signaling included in the first signal, the upper layer control signaling including an indication of a location of a control resource located in LTE subframes, the control resource comprising at least one physical resource block (PRB) including at least one control channel element (CCE) designated for the receiving device;
receive a second signal; and
decode the at least one CCE from the received second signal using the upper layer control signaling to recover a control channel for the receiving device.
12. The non-transitory computer readable medium of claim 11 , wherein the receiving device is a user equipment (UE).
13. The non-transitory computer readable medium of claim 11 , wherein the upper layer control signaling includes an indication of a starting symbol that the receiving device should monitor for the at least one CCE in the control resource located in the LTE subframes.
14. The non-transitory computer readable medium of claim 11 , wherein the first signal and the second signal are received from an eNB.
15. The non-transitory computer readable medium of claim 11 , wherein the at least one PRB is semi-statically allocated.
