摘要： Various methods of control-less data transmission for NB-IoT/NR devices have been proposed to improve efficiency and system capacity in cellular networks. In a first embodiment, a PDCCH-less operation is performed between eNB and UE. UE will blindly decode some PDSCH subframes according to the parameters configured by higher layer. In a second embodiment, a PDCCH-lite operation is performed between eNB and UE. UE may use one PDCCH to schedule more than one subsequent PDSCH resources. In a third embodiment, an extremely compact DCI (E-DCI) format is used between eNB and UE. When the same assignment parameters are used by the eNB for the UE, DCI overhead may be reduced by E-DCI. In a fourth embodiment, direct data transmission in PDCCH is performed between eNB and UE. Data transmission is directly transmitted by PDCCH with a new DCI format.

摘要： Narrowband downlink control channel (NB-PDCCH) design for Narrowband Internet of Thing (IoT) devices is proposed. In one novel aspect, NB-PDCCH spans both first and second slots in the region of legacy physical downlink shared channel (PDSCH). A plurality of physical resource blocks (PRBs) is allocated for NB-PDCCH transmission that carry downlink control information (DCI). Furthermore, each NB-IoT device can be configured with nPRB PRB pairs for NB-PDCCH transmission (e.g., nPRB=1, 2, 4, or 8), and an NB-PDCCH transmission time interval (TTI) is composed by nPRB subframes. An NB-PDCCH is encoded and occupies multiple narrowband control channel elements (NCCEs) based on aggregation level. In a preferred embodiment, each PRB pair for NB-PDCCH occupies two NCCEs.
