NPBCH: The NPBCH is used to carry the 34 bit MIB-NB (TS 36.212 6.4.1 [ 2 ]). The MIB-NB is coded to form a 1600 bits codeword (TS 36.211 10.2.4.1 [ 1 ]). The codeword is evenly segmented into 8 sub-blocks, each one has 200 bits which are transmitted on subframe 0 and repeated in the 7 following consecutive frames (TS 36.211 10.2.4.4 [ 1 ]). The mapping of the codeword bits is illustrated in the figure below.NPDSCHDataType: Type of data the NPDSCH carries, the allowed values are either 'BCCHNotSIB1NB' or 'NotBCCH'.

NAS Rrc pdcp rlc mac phy. Ue NPDSCH: The key feature of NPDSCH is subframe repetition. NB-IoT defines two repetition schemes for the case when NPDSCH is carrying broadcast control channel (BCCH) or not. BCCH is the logical channel to carry SIB1-NB, system information messages, etc. Not carrying BCCH implies that NPDSCH may carry Paging Control Channel (PCCH), Common Control Channel (CCCH), Dedicated Control Channel (DCCH), Dedicated Traffic Channel (DTCH), etc (TS 36.300 6.1.3.2 and 5.3.1a [ 6 ]). The two repetition schemes are illustrated in the figure below. The NPDSCH repetition parameters includes the number of subframes in a codeword NSF and the number of repetitions NRep. The example in the figure shows the repetition pattern with NRep = 4 for the case when NPDSCH is carrying BCCH and NRep = 8 for the case when NPDSCH is not carrying BCCH and NSF = 3 for both cases. For the case when carrying BCCH, all the subframes of a codeword are transmitted before repeating the codeword. For the case when not carrying BCCH, a subframe in the codeword is repeated by min(NRep,4) before performing the same repetition for the other subframes. After the codeword is repeated by min(NRep,4) times, the same procedure is performed until the full repetition is complete, i.e., repeated by NRep times. The detailed specification of the repetition scheme can be found in TS 36.211 10.2.3 [ 1 ].NRep: Number of repetitions for a NPDCCH candidate (TS 36.213 16.6 [ 3 ]). Allowed values are , where n = 1...10.

NB-IoT is designed to connect a large number of devices in a wide range of application domains For NB-IoT UE, only the following radio bearers are defined: SRB0: Used for carrying RRC signalling.. In-band mode can be further grouped depending on the physical cell identity (PCI) used, Inband-SamePCI and Inband-DifferentPCI. If Inband-SamePCI, the physical layer cell identity and PCI are the same and the UE can make assumptions about the ports and channel from LTE signals. The operation mode is indicated in the NB-IoT master information block (MIB-NB), which provides essential information for the user equipment (UE). The network can use radio resource control information to allocate a non-anchor carrier to an UE operating in an anchor carrier, see TS 36.331 6.7.3.2 [ 5 ] and section 7.3.2.4 in [ 9 ].

  2. NPDSCH: For operation modes Standalone and Guardband, the REs is punctured by NRS only; for in-band operation modes, the REs is punctured by both NRS and CRS. When the operation mode is in-band, the first 3 OFDM symbols in the subframe are not used for NPDSCH carrying SIB1-NB, the first ControlRegionSize OFDM symbols in the subframe are not used when NPDSCH is carried by a NB-IoT downlink subframe. ControlRegionSize is a parameter field in structure ngen.Config to configure the LTE control region size for NPDSCH RE allocations (TS 36.211 10.2.3.4 [ 1 ], TS 36.213 16.4.1.4 [ 3 ] and TS 36.331 6.7.2 [ 5 ]).

Buy Bitcoin, Ethereum, XRP or Litecoin, then securely store it in your.. NPDCCH: The NRS and CRS puncturing are the same as that in NPDSCH described above. When the operation mode is in-band, the first ControlRegionSize OFDM symbols in the subframe are not used for NPDCCH. Same as that for NPDSCH, ControlRegionSize is used to configure the NPDCCH RE allocations (TS 36.211 10.2.3.4 [ 1 ], TS 36.213 16.4.1.4 [ 3 ] and TS 36.331 6.7.2 [ 5 ]).

NPBCH: The REs are punctured by the NRS and the CRS using the maximum number of NRS and CRS antenna ports (2 and 4, respectively), for both operation modes (TS 36.211 10.2.4 [ 1 ]). This is because the UE has no knowledge about the number of used antenna ports and the operation mode. Alibaba.com offers 6,656 nb iot products. About 1% of these are Alarm.

A SIB1-NB is carried in 8 subframes (NSF = 8), and mapped to subframe 4 in every other frame in 16 continuous frames which are repeated NRep times (NRep = 4, 8 or 16, see TS 36.213 16.4.1.3 Table 16.4.1.3-3 [ 3 ]). The repetitions are equally spaced within a period of 256 frames (TS 36.331 5.2.1.2a [ 5 ]). The starting frame number for the first NPDSCH transmission in the period depends on the narrowband physical cell identity NNCellID as well as the number of repetitions NRep (TS 36.213 16.4.1.3 Table 16.4.1.3-4 [ 3 ]).
