MULTIPLEXING METHOD FOR NARROWBAND INTERNET OF THINGS PHYSICAL DOWNLINK CHANNEL, AND BASE STATION AND USER EQUIPMENT

摘要

Embodiments of the present disclosure provide a multiplex transmission method for narrowband Internet of Things physical downlink channels, and a corresponding base station and user equipment for executing the method. The base station according to the embodiments of the present disclosure comprises a mapping unit, configured to multiplex more than one narrowband Internet of Things physical downlink channel in the same subframe, wherein the narrowband Internet of Things physical downlink channels comprise narrowband Internet of Things physical downlink control channels (NB-PDCCHs) and/or narrowband Internet of Things physical downlink shared channels (NB-PDSCHs), a minimum granularity for resource allocation of the narrowband Internet of Things physical downlink channels is in a unit of an enhanced resource element group (EREG), and the EREG is composed of multiple resource elements defined in two dimensions of time and frequency in the same subframe; and a transmitting unit, configured to transmit a downlink subframe.
