Channel configuration and downlink/uplink configuration for narrow band internet of things (NB-IoT) systems
Methods, systems, and storage media are described for the indication of frequency hopping and downlink (DL)/uplink (UL) configuration in narrowband Internet-of-Things (NB-IoT) systems. Other embodiments may be described and/or claimed.
1. An apparatus comprising:
memory to store downlink (DL)/uplink (UL) configuration information; and
processing circuitry, coupled with the memory, to:
retrieve the DL/UL configuration information stored in the memory;
generate a message comprising a master information block (MIB) that includes the DL/UL configuration information; and
encode the message for transmission to a user equipment (UE),
wherein the MIB further includes channel whitelist information that includes a frequency hopping indication for use in an unlicensed narrowband Internet of things (NB-IoT) spectrum, and wherein the channel whitelist information indicates a channel number and a channel group utilized for frequency hopping.
2. The apparatus of claim 1 , wherein the DL/UL configuration information comprises a three-bit indicator for indicating one of eight DL/UL subframe configurations.
3. The apparatus of claim 1 , wherein the DL/UL configuration information indicates: two downlink channels and eighteen uplink channels, ten downlink channels and ten uplink channels, four downlink channels and thirty-six uplink channels, or eight downlink channels and seventy-two uplink channels.
4. The apparatus of claim 1 , wherein the DL/UL configuration is configured per channel dwell.
5. The apparatus of claim 4 , wherein the DL/UL configuration crosses two or four channel dwell periods.
6. The apparatus of claim 1 , wherein the DL/UL configuration includes multiple DL/UL switches.
7. The apparatus of claim 1 , wherein the channel whitelist information includes one or more bitmaps associated with the frequency hopping indication.
8. The apparatus of claim 1 , wherein the channel whitelist information comprises a state indicating all channels within the channel group are to be utilized for frequency hopping.
9. The apparatus of claim 1 , wherein the channel whitelist information indicates that the UE is to perform transmission and reception on a channel upon which it received a primary synchronization signal (PSS), secondary synchronization signal (SSS), or physical broadcast channel (PBCH) for initial access.
10. The apparatus of claim 1 , wherein the channel whitelist information indicates a separate physical channels index for anchor channels and data channels.
11. The apparatus of claim 10 , wherein the channel whitelist information indicates thirty channels for anchor channel transmission and two groups of fifty data channels.
12. The apparatus of claim 10 , wherein the channel whitelist information indicates five channels for anchor channel transmission and five groups of twenty-five data channels.
13. One or more non-transitory, computer-readable media storing instructions, that, when executed by one or more processors, cause a next-generation NodeB (gNB) to:
generate a message comprising a master information block (MIB) that includes an indicator of downlink (DL)/uplink (UL) configuration information; and
encode the message for transmission to a user equipment (UE), wherein the indicator of the DL/UL configuration information is a three-bit indicator for indicating one of eight DL/UL subframe configurations.
14. The one or more non-transitory, computer-readable media of claim 13 , wherein the DL/UL configuration information indicates: two downlink channels and eighteen uplink channels, ten downlink channels and ten uplink channels, four downlink channels and thirty-six uplink channels, or eight downlink channels and seventy-two uplink channels.
15. One or more non-transitory, computer-readable media storing instructions, that, when executed by one or more processors, cause a next-generation NodeB (gNB) to:
generate a master information block (MIB) message comprising downlink (DL)/uplink (UL) configuration information for an unlicensed narrowband Internet of things (NB-IoT) spectrum; and
encode the MIB message for transmission to a user equipment (UE),
wherein the MIB further includes channel whitelist information that includes a frequency hopping indication for use in an unlicensed narrowband Internet of things (NB-IoT) spectrum, and wherein the channel whitelist information indicates a channel number and a channel group utilized for frequency hopping.
16. The one or more non-transitory, computer-readable media of claim 13 , wherein the DL/UL configuration information includes a three-bit indicator for indicating one of eight DL/UL subframe configurations.
17. The one or more non-transitory computer-readable media of claim 13 , wherein the DL/UL configuration information is configured per channel dwell.
18. The one or more non-transitory computer-readable media of claim 17 , wherein the DL/UL configuration crosses two or four channel dwell periods.
19. The one or more non-transitory computer-readable media of claim 15 , wherein the channel whitelist information includes one or more bitmaps associated with the frequency hopping indication.
20. The one or more non-transitory computer-readable media of claim 15 , wherein the channel whitelist information comprises a state indicating all channels within the channel group are to be utilized for frequency hopping.
