Symbol puncture for unlicensed narrowband internet of things (NB IoT)

1. An apparatus of a user equipment (UE) operable for narrowband (NB) internet of things (IoT), the apparatus comprising:

one or more processors configured to:

decode, at the UE, a special subframe from a data segment carried on an nframe that is transmitted in a data channel;

identify, at the UE, a downlink pilot time slot (DwPTS) and a guard period (GP) from the special subframe;

switch, at the UE, from receiving in the data channel to transmitting in the data channel during a duration of the special subframe, wherein to switch comprising switching from downlink reception in a downlink subframe to uplink transmission in an uplink subframe, wherein an initial 14 orthogonal frequency division multiplexing (OFDM) symbols of the uplink subframe are punctured; and

a memory interface configured to send the DwPTS and the GP to a memory.

2. The apparatus of claim 1 , wherein the one or more processors are further configured to:

identify, at the UE, the DwPTS comprised of 10 OFDM symbols and the GP comprised of 4 OFDM symbols.

3. The apparatus of claim 1 , wherein the one or more processors are further configured to:

identify, at the UE, the DwPTS comprised of 7 OFDM symbols and the GP comprised of 7 OFDM symbols.

4. The apparatus of claim 1 , further comprising a transceiver configured to:

receive, at the UE, the special subframe from the data segment carried on the nframe that is transmitted in the data channel.

5. The apparatus of claim 1 , wherein the UE includes an antenna, a touch sensitive display screen, a speaker, a microphone, a graphics processor, an application processor, an internal memory, a non-volatile memory port, or combinations thereof.

6. An apparatus of a base station operable for narrowband (NB) internet of things (IoT), the apparatus comprising:

one or more processors configured to:

encode, at the base station, a special subframe from a data segment carried on an nframe that is transmitted in a data channel;

encode, at the base station, a downlink pilot time slot (DwPTS) and a guard period (GP) in the special subframe; and

encode, at the base station, the special subframe that enables a UE to switch from receiving in the data channel to transmitting in the data channel during a duration of the special subframe, wherein the special subframe is encoded to enable the UE to switch from downlink reception in a downlink subframe to uplink transmission in an uplink subframe, wherein an initial 14 orthogonal frequency division multiplexing (OFDM) symbols of the uplink subframe are punctured; and

a memory interface configured to send the DwPTS and the GP to a memory.

7. The apparatus of claim 6 , wherein the one or more processors are further configured to:

encode, at the base station, the DwPTS comprised of 10 OFDM symbols and the GP comprised of 4 OFDM symbols; or

encode, at the base station, the DwPTS comprised of 7 OFDM symbols and the GP comprised of 7 OFDM symbols.

8. The apparatus of claim 6 , wherein the one or more processors are further configured to:

encode, at the base station, an anchor channel and a non-anchor channel for transmission to the UE.

9. The apparatus of claim 8 , wherein a final two OFDM symbols of a MulteFire (MF) narrowband physical broadcast channel (NPBCH) (MF-NPBCH) of the anchor channel are punctured at the UE.

10. The apparatus of claim 8 , wherein an initial two OFDM symbols of an initial downlink subframe of the non-anchor channel are punctured at the UE.

11. At least one non-transitory machine readable storage medium having instructions embodied thereon for narrowband (NB) internet of things (IoT) communication, the instructions when executed by one or more processors at a user equipment (UE) perform the following:

decoding, at the UE, a special subframe from a data segment carried on an nframe that is transmitted in a data channel;

identifying, at the UE, a downlink pilot time slot (DwPTS) and a guard period (GP) from the special subframe; and

switching, at the UE, from receiving in the data channel to transmitting in the data channel during a duration of the special subframe by switching from downlink reception in a downlink subframe to uplink transmission in an uplink subframe, wherein an initial 14 orthogonal frequency division multiplexing (OFDM) symbols of the uplink subframe are punctured.

12. The at least one non-transitory machine readable storage medium of claim 11 , further comprising instructions that when executed perform:

identifying, at the UE, the DwPTS comprised of 10 OFDM symbols and the GP comprised of 4 OFDM symbols.

13. The at least one non-transitory machine readable storage medium of claim 11 , further comprising instructions that when executed perform:

identifying, at the UE, the DwPTS comprised of 7 OFDM symbols and the GP comprised of 7 OFDM symbols.

14. The at least one non-transitory machine readable storage medium of claim 11 , further comprising instructions that when executed perform:

switching from transmission in an anchor channel to transmission in the data channel.
