Fig. 1 shows and can for example represent and (can realize the technology of the discontinuous mapping for time-domain resource wherein) The Illustrative Operating Environment 100 of some embodiments.Operating environment 100 may include mobile device 102 and cellular base station 104.Behaviour Make the part that environment 100 is considered the network for realizing the wireless communication between mobile device 102 and base station 104.It moves Dynamic equipment 102 interface 106 can be communicated with base station 104 by radio communication.Mobile device 102 can be can be with one Or the arbitrary mobile computing device that multiple cordless communication networks are wirelessly communicated.As an example, mobile device 102 can be The IoT equipment that can be wirelessly communicated with cellular base station 104 in opposite narrowband frequency range.Mobile device 102 can be with It is user equipment (UE).Base station 104 can be cellular base station, for example, evolution node B (eNB).Wireless communication interface 106 can be with Be for example for arbitrary wireless network described herein or standard (including for example, 4G, LTE or 5G wireless network, or specifically, NB-IoT technologies and/or standard (for example, 3GPP LTE NB-IoT standards)) wireless interface.As an example, mobile device 102 Can be intelligence instrument, which may be coupled to or be incorporated into for transmitting and the information of associated device-dependent Bigger equipment (intelligence instrument is it is possible thereby to which it is motionless or fixed to be considered relative to the bigger equipment).Mobile device 102 and base station 104 technology of the discontinuous mapping as described herein for time-domain resource may be implemented.

Operating environment 100 (including it forms component, including mobile device 102 and base station 104) can be according to 3GPP LTE NB-IoT standards are operated.Operating environment 100, mobile device 102 and base station 104 can support such as three kinds of different behaviour Operation mode, i.e. independent manipulation mode, protection band operation mode and with interior operation mode.For independent manipulation mode and protection band Operation mode, all resources in NB-IoT carrier waves may be used to the transmission of NB-IoT signals and channel.NB-IoT carrier waves are logical May include often a tradition LTE Physical Resource Block (PRB), tradition LTE Physical Resource Block corresponds to the son with 15kHz and carries The system bandwidth of the 180kHz of wave spacing.LTE NB-IoT (or NB-LTE) can be based on the orthogonal frequency in downlink (DL) Single-carrier frequency division multiple access (SC-FDMA) in multiple access (OFDMA) and uplink (UL).

The NB-IoT physical layer designs that can be used in operating environment 100 can be used to be defined for traditional LTE system Channel subset.Other channels may not be defined for NB-IoT systems.NB-IoT UE (for example, mobile device 102) can With the appropriate cell for executing cell searching to identify for being connected to internet.In the first step, NB-IoT UE 102 can be with Attempt detection narrowband primary synchronization signal (NB-PSS).NB-IoT UE 102 can also use NB-PSS to make its clock and NB- IoT Network Synchronizations and the character boundary for detecting OFDM waveforms.In the second step, NB-IoT UE 102 can attempt to use Narrowband secondary synchronization signal (NB-SSS) obtains downlink subframe and frame timing (frame timing) and NB-IoT carrier waves Physical district ID (PCI).According to cell ID and radio frame synchronization, UE 102 can continue to decode narrowband Physical Broadcast Channel (NB-PBCH), which may include the scheduling information transmitted for additional system information.Obtain NB-IoT system informations To enable NB-IoT UE 102 initiate random access (RA) process to be attached to NB-IoT networks.The network can use Random access response (RAR) responds random access procedure.Random access procedure allow network configuration NB-IoT UE 102 with It is communicated in network, and may include contention resolved process.After a connection is established, network can be used specific to small Area and NB-IoT UE 102 are configured specific to radio resource control (RRC) parameter of UE, to controlling NB-IoT UE 102 transmission and reception behavior features.

NB-IoT UE 102 and network (via and include base station 104) between communication can be by under narrowband physics Uplink Control Channel (NPDCCH) is scheduled (may not include random access channel (RACH)).NPDCCH can be by downlink Link control message (DCI) is transmitted to NB-IoT UE 102 from eNodeB 104, which can be in downlink and uplink Narrowband physical down link sharing channel (NPDSCH) transmission and/or narrowband physical uplink shared channel are dispatched in road respectively (NPUSCH) it transmits.It may not be needed other channels in NB-LTE systems, but be also not excluded for other channels.

The demodulation of narrowband Physical Broadcast Channel (NPBCH), NPDCCH, and/or NPDSCH can be based on cell specific reference Signal (CRS), demodulated reference signal (DMRS) or narrowband reference signal (NB-RS).In addition it is possible to use different reference letters Number modulate different channels.Finally, individual channel can be demodulated using several reference signals.For example, NPBCH can be used NB-RS is demodulated, and NPDCCH can be demodulated using CRS.In different examples, it is in good in NB-IoT UE 102 NPDCCH can be demodulated using CRS when coverage condition, and other NB-IoT UE (not shown in FIG. 1 for the sake of simplicity) can NPDCCH is demodulated to use CRS and NB-RS.

With reference to NPDCCH (no matter its detailed physical layer (PHY) design), it may be necessary to allow NB-IoT UE (for example, moving Dynamic equipment 102) mechanism of decoding NPDCCH in the case of the priori of the physical resource not for sending NPDCCH.With NPDSCH and NPUSCH it is different (transmission of NPDSCH and NPUSCH are scheduled by DCI, DCI include the resource allocation of transmission with And adaptive modulation and coding (AMC) scheme), NB-IoT UE 102 may need in the case of no this priori Decode NPDCCH.

Assuming that the fixed modulation scheme (for example, quadrature phase shift keying (QPSK)) and the certainty of DCI for NPDCCH have Magnitude of load is imitated, eNB schedulers can be by dynamically changing the resource element in the time frequency grid for distributing to given NPDCCH (RE) quantity come adjust NPDCCH transmission code check.NB-IoT UE 102 can be usually directed to when attempting decoding NPDCCH Possible NPDCCH transmission blind decoding is referred to as the physical resource collection of the definition of search space (SS), is thus waited for NPDCCH The cyclic redundancy check (CRC) of choosing by when NPDCCH is successfully decoded.

Search space is considered the logical concept that physical resource is mapped to by control channel element (CCE). Herein, narrowband control channel element (NCCE) can indicate the mapping of the physical resource elements for being defined into NPDCCH CCE.Specifically, NB-IoT UE (for example, mobile device 102) can be attempted for the different codes for being referred to as polymerization grade (AL) Rate is assumed to decode NPDCCH, and thus each AL is mapped to the NCCE for the different number for assuming the transmission for NPDCCH.In addition, Every group of NCCE in subframe can be repeated as many times according to levels of repetition (RL).In other words, NPDCCH candidates are according to AL, starting NCCE indexes and the RL (m) of given NPDCCH candidates are defined.

Number of candidates (that is, blind decoding trial) for given AL is priori for UE 102, as search space is fixed Justice.In addition, search space definition may include hash function, for cross-subframe randomization CCE indexes to prevent different NB-IoT Obstruction between UE.For further processing be directed to NPDCCH transmission and NPDSCH transmission both obstruction in terms of, NPDCCH and NPDSCH can be mapped to (for example, on time) discontinuous subframe at least for the UE in extension or extreme coverage condition Set.In one example, these coverage conditions may map to the maximum coupling loss (MCL) of 154dB and 164dB.In addition, In view of each subframe available limited resources quantity in a frequency domain, the starting subframe of the NPDSCH by neatly indicating scheduling It neatly indicates time-domain resource, can further provide for dispatching flexibility.

Technique described herein is by support for the discontinuous transmission of NPDCCH and NPDSCH and for NPDSCH's Domain scheduling promotes this flexibility when flexibly.

As described above, being directed to NB-IoT systems, limited resources can be obtained in a frequency domain (for example, 1 PRB is crossed over 180kHz).As a result, being directed to NB-IoT systems, possibly rely on for identical or different UE (for example, mobile device 102) NPDCCH and NPDSCH downlink (DL) transmission between the multiplexing based on time division multiplexing (TDM).In addition, in order to place Coverage enhancement is provided in the UE of bad channel condition, NPDCCH and NPDSCH transmission may need to be repeated as many times.For medium big The transmission of small payload (for example,~500 to 1000 information), single NPDSCH transmission blocks (TB) can also be mapped To multiple DL subframes.

NPDCCH can be sent using one or two of subframe NB-CCE, one or two of subframe NB- CCE can be repeated in subsequent subframe to provide required covering.Although in the UE well covered, up to two in this way The NPDCCH transmission of UE can be re-used by the FDM in subframe, still (AL equal to 2) enabling machine type communication (MTC) user PDCCH signals (M-PDCCH signals) can be re-used by TDM.

In addition, in order to reduce the time domain number of repetition needed for UE receptions NPDSCH, NPDSCH can occupy each subframe All available resources-in PRB pair between NPDCCH and NPDSCH or between two NPDSCH are transmitted that is, can not use FDM。

In consideration of it, as described above, in order to provide enough dispatching flexibilities and avoid that a large amount of repetition/subframes may be needed NPDCCH the or NPDSCH transmission blockings NPDCCH or NPDSCH transmission for going to UE, the time-domain resource of sub-frame level it is discontinuous Mapping can be used for both NPDCCH and NPDSCH transmission.By (associated) NB- for allowing NB-PDCCH and scheduling Flexible time interval (rather than Fixed Time Interval) between PDSCH, can further provide for additional flexibility.

Therefore, there is provided herein for providing the technology for being directed to the discontinuous time-domain resource of NPDCCH and NPDSCH and mapping.
