Methods and apparatuses for transmitting downlink control signaling on wireless relay link

摘要

Using an allocated control channel resource in a relay transmission frame, with an identified starting point, in a semi-static allocation scheme is disclosed. The control signaling may be mapped to the allocated control channel resource using different mapping schemes. Also disclosed is decoding a control channel element from a relay transmission frame received via a wireless relay link. The control channel resource associated with the relay transmission frame may be allocated in a semi-static allocation scheme. A starting indicator may be extracted from the decoded control channel element. A part of control signaling may be extracted from the decoded control channel element using the extracted starting indicator.

主权项

1. An apparatus comprising:
a processor configured to allocate, to a wireless relay link, a control channel resource of a relay transmission frame, with an identified starting point, in a semi-static allocation scheme; the processor is further configured to generate control signaling based on a status of the wireless relay link; the processor is further configured to map the control signaling to the allocated control channel resource via any one of a time-first mapping, a frequency-first mapping, or a multiplexing mapping; and a transceiver configured to transmit the mapped control signaling on the wireless relay link to an associated relay node.
