METHOD AND APPARATUS FOR SENDING CONTROL INFORMATION WITH ENHANCED COVERAGE IN A WIRELESS NETWORK

摘要

Techniques for sending control information in a manner to improve reliability are described. In an aspect, control information may be sent on multiple control channels, which may be independently configured and operated, in order to improve reliability. In one design, a base station may send signaling to instruct at least one UE to receive control information on both a first control channel (e.g., a Physical Downlink control Channel (PDCCH)) and a second control channel (e.g., a Relay PDCCH (R-PDCCH)). The base station may send control information for the at least one UE on the first and second control channels, e.g., in different time and/or frequency regions of a subframe. In another aspect, control information may be sent on a control channel in multiple subframes with bundling to improve reliability. A user equipment (UE) may perform the complementary processing to recover the control information sent by the base station on multiple control channels or with bundling.
