Grid Design for Introducing Gaps in Transmission for DL NB-IOT

A network node comprising:

• a memory;
• and
• processing circuitry communicatively coupled to the memory, the processing circuitry configured to:
• communicate, over a narrowband Internet of Things downlink, a first message to a first wireless device during repetition periods of at least a first time frame and a second time frame of a plurality of time frames of a transmission time of a narrowband physical downlink control channel (NB-PDCCH) or a narrowband physical downlink shared channel (NB-PDSCH). each time frame of the plurality of time frames comprising a repetition period and a gap;
• and
• communicate a second message to a second wireless device during a gap of the first time frame.

A wireless device comprising:

• a memory;
• and
• processing circuitry communicatively coupled to the memory, the processing circuitry configured to:
• receive, over a narrowband Internet of Things downlink, a configuration indicating a subframe in which a communication over a narrowband physical downlink control channel (NB-PDCCH) is scheduled to be communicated;
• receive the communication over the NB-PDCCH in the subframe Indicated by the configuration;
• and
• decode the communication.

A method comprising:

• receiving, over a narrowband Internet of Things downlink, a configuration indicating a subframe in which a communication over a narrowband physical downlink control channel (NB-PDCCH) is scheduled to be communicated;
• receiving communication over the NB-PDCCH in the subframe indicated by the configuration;
• and
• decoding the communication.
