Method and system for allocating resources of relay link-physical downlink control channel

摘要

The disclosure provides a method and system for allocating resources of a Relay link-Physical Downlink Control Channel (R-PDCCH). The method includes that: a network side configures a resource allocation way of the R-PDCCH (400); a relay node receives control information carried in the R-PDCCH in accordance with the configured resource allocation way (401). The disclosure provides a specific solution for implementing the resource allocation of the R-PDCCH.

1. A method for allocating resources of a Relay link-Physical Downlink Control Channel (R-PDCCH), comprising:
configuring a resource allocation way of the R-PDCCH by a network side; receiving control information carried in the R-PDCCH by a relay node in accordance with the configured resource allocation way; wherein the resource allocation way comprises one or more resource allocation domains configured to carry signalling corresponding to resource allocation; the resource allocation domain is configured according to one of or any combination of the following: resource allocation type, demodulation pilot type, grant information type, service channel and control channel multiplexing type and scheduling type; wherein when configured according to the resource allocation type, the resource configuration way is a centralized resource allocation domain and/or a distributed resource allocation domain; when configured according to the demodulation pilot type, the resource configuration way is a resource allocation domain based on a Demodulation Reference Signal (DMRS) and/or a resource allocation domain based on a Cell-specific Reference Signal (CRS); when configured according to the grant information type, the resource configuration way is a resource allocation domain based on Relay link-Downlink grant (R-DL grant) and/or a resource allocation domain based on Relay link-Uplink grant (R-UL grant); when configured according to the service channel and control channel multiplexing type, the resource configuration way is a resource allocation domain based on Frequency Division Multiplexing (FDM) and/or a resource allocation domain based on FDM+Time Division Multiplexing (TDM); when configured according to the scheduling type, the resource configuration way is a resource allocation domain based on frequency diversity scheduling and/or a resource allocation domain based on frequency selective scheduling.
