Abstract
Embodiments described herein relate to time division duplexing (TDD) support for in-band, guard band, and standalone operation modes of narrowband internet-of-things (NB-IoT) systems. At least one example is directed to an indication technique for transmission of a narrowband system information block type 1 (SIB1-NB) on a carrier.
Claims22
One or more non-transitory computer-readable storage media including computer executable instructions for supporting time division duplexing (TDD) in a narrowband internet-of-things (NB-IoT) system, wherein the instructions, when executed by one or more processors, cause the one or more processors to:
- receive a narrowband master information block (MIB-NB);
- determine, based on the MIB-NB, information associated with a carrier;
- determine, based on the information, bandwidth information associated with the carrier;
- determine one or more physical resource block (PRB) offset values based on the bandwidth information;
- and
- receive, based on the one or more PRB offset values, a narrowband system information block type 1 (SIB1-NB) on the carrier.
One or more non-transitory computer-readable storage media including computer executable instructions for supporting time division duplexing (TDD) in a narrowband internet-of-things (NB-IoT) system, wherein the instructions, when executed by one or more processors, cause the one or more processors to:
- receive a narrowband master information block (MIB-NB);
- determine, based on the MIB-NB, that a narrowband system information block type 1 (SIB I-NB) is to be transported on a first carrier or a second carrier;
- in response to determining that the SIB1-NB is to be transported on the first carrier, identify, based at least in part on the MIB-NB, bandwidth information;
- determine one or more physical resource block (PRB) offset values based on the bandwidth information;
- determine, based on the one or more PRB offset values, an identity of the first carrier that will transport the SIB1-NB;
- and
- receive the SIB1-NB on the identified first carrier.
An apparatus for use in supporting time division duplexing (TDD) in a narrowband internet-of-things (NB-IoT) system, the apparatus comprising:
- memory circuitry;
- and
- processing circuitry, coupled with the memory circuitry, to:
- receive a narrowband master information block (MIB-NB);
- determine, based on the MIB-NB, information associated with a carrier;
- store the information associated with the carrier in the memory circuitry;
- determine, based on the information, bandwidth information;
- determine one or more physical resource block (PRB) offset values based on the bandwidth information;
- and
- receive, based on the one or more PRB offset values, a narrowband system information block type 1 (SIB1-NB) on the carrier.
An apparatus for use in supporting time division duplexing (TDD) in a narrowband internet-of-things (NB-IoT) system, comprising:
- means for transmitting a narrowband master information block (MIB-NB), the MIB-NB including information associated with a carrier;
- and
- means for transmitting a narrowband system information block type 1 (SIB1-NB) on the carrier,
- wherein the information includes bandwidth information, and
- wherein bandwidth information corresponds to one or more physical resource block (PRB) offset values associated with the carrier.
