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