Abstract
This disclosure relates to providing system information for cell access to link budget limited devices. According to some embodiments, a base station may transmit an announcement information block (AIB) in a downlink shared data channel (e.g., PDSCH), wherein the AIB contains information useable by a UE in determining the location of system information in the downlink shared data channel. The UE can thus determine the location of and decode system information without having to decode a downlink control channel (e.g., PDCCH). This may be important for certain classes of devices, such as link budget limited devices, which have issues in decoding the downlink control channel. Improved paging scheduling techniques are also disclosed which more efficiently use PDCCH paging resources.
