Design of common search space for enhanced coverage in wireless communication

摘要

Methods, systems, and devices for wireless communication are described. The base station and user equipment (UE) may utilize an enhanced physical downlink control channel (ePDCCH) in a common search space to establish a MulteFire connection. The common search space may include common PDCCH (C-PDCCH) and MulteFire system information block (SIB-MF1) grant. The base station may define one or more common search spaces for SIB-MF1 grants and C-PDCCH, and signal resource allocation for common search spaces to the UE within a master information block (MIB). Each common search space may include a fixed set of control elements that monitor the UE to decode SIB-MF1 grants and C-PDCCH. In some cases, the base station may hardcode resources for SIB-MF1 grants and C-PDCCH. Alternatively, the base station may signal resources for each of the SIB-MF1 grants and C-PDCCH through reserved bits in the MIB.
