Indication and processing method and device for resource occupancy mode

摘要

There is disclosed a method of indicating a resource occupancy scheme and processing a resource occupancy scheme indicator so as to enable a UE to be aware a resource occupancy scheme of the network side and avoid an unnecessary power waste and unnecessary interference, and in the method, a base station generates a corresponding resource indicator for a resource occupancy scheme of a legacy control resource area and an enhanced control resource area in each downlink subframe to be transmitted in a specific periodicity and sends the resource indicator to a UE in a resource indication message, and the UE determines from the obtained resource indicator the resource occupancy scheme of the legacy control resource area and the enhanced control resource area in each downlink subframe to be transmitted in the specific periodicity and performs a corresponding resource handling mode, so that the UE can blindly detect in PDCCH common and user spaces or receive control information carried on PHICH resource at an accurate position to thereby avoid an unnecessary power waste of and unnecessary interference to the UE due to blind detection or reception and improve effectively the performance of a system.

1. A method of indicating a resource occupancy scheme, comprising:
a base station determining downlink subframes to be transmitted and determining respectively a resource occupancy scheme of a legacy control resource area and an enhanced control resource area in each downlink subframe to be transmitted; and the base station generating a resource indicator for the resource occupancy scheme of the legacy control resource area and the enhanced control resource area in each downlink subframe to be transmitted in a specific periodicity and sending the resource indicator to a User Equipment (UE) in a resource indication message to instruct the UE to determine from the obtained resource indicator the resource occupancy scheme of the legacy control resource area and the enhanced control resource area in each downlink subframe to be transmitted in the specific periodicity; wherein the base station sending the resource indicator to the UE in the resource indication message to instruct the UE to determine from the obtained resource indicator the resource occupancy scheme of the legacy control resource area and the enhanced control resource area in each downlink subframe to be transmitted in the specific periodicity, comprises: the base station sending the resource indicator to the UE in the resource indication message to instruct the UE to determine from the obtained resource indicator that control information is transmitted from the network side neither in the legacy control resource area nor in the enhanced control resource area, or that control information is transmitted from the network side in the legacy control resource area and/or the enhanced control resource area, respectively in each downlink subframe to be transmitted in the specific periodicity; wherein before the downlink subframes to be transmitted are determined, the base station configures the resource occupancy scheme of any downlink subframe at least by: the base station determining whether a downlink subframe to be configured is an Almost Blank Subframe (ABS) subframe, and if it is not an ABS subframe, then configuring control information transmission in the legacy control resource area and/or the enhanced control resource area in the downlink subframe; or if it is an ABS subframe, then configuring no control information transmission in the legacy control resource area in the downlink subframe but control information transmission in the enhanced control resource area in the downlink subframe.
