Abstract
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.
Claims20
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.
5 more elements
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.
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.
