  • OFDM orthogonal frequency division multiplexing
  • LTE and NR networks have to coexist.
  • LTE and NR base stations could operate on separate spectrum and the coexistence between NR and LTE radios would not be much different than in existing networks where multiple RATs (e.g., GSM, UMTS, LTE) also coexist.
  • multiple RATs e.g., GSM, UMTS, LTE
  • guard intervals could be very costly and inefficient, especially in unpaired spectrum where uplink and downlink are dime-division multiplexed and guards would have to be provisioned that isolate each RAT from cross-link interference stemming from other RATs with uncoordinated UL/DL switching intervals.

  • the former may not be possible or feasible if the LTE and NR networks belong to separate operators but for the second case, the two networks may not belong to the same mobile network operation (MNO) or eNB of same network. In case they do belong to the same MNO, it is important to distinguish whether the "eNBs" controlling the LTE and NR networks are collocated or not, or more precisely, if coordination among them can be assumed and if so, on which time scale such coordination can occur (e.g., ideal versus non-ideal backhaul between the LTE and NR eNBs).

  • 3GPP RAN1 has agreed to study at least the following two subframe structures: a. a DL transmission region (containing data assignments and data), followed by a guard region, followed by a UL transmission region (containing UCI); and b. DL transmission region (containing data assignments), followed by a guard region, followed by a UL transmission region (containing data, UCI).

  • This can be similar to LTE Rel. 8 with control format indicator (CFI) equals 1 and 1 2 UL symbols such as where the first symbol carrying the DCI on a PDCCH is followed by a guard symbol for duplex switching in the transceiver and the remaining 1 2 symbols in a subframe are used for UL transmissions.

  • a semi-static TDD UL/DL configuration could designate each subframe in a radio frame as DL or UL and the 14 symbols within it would accordingly be all UL or DL.
  • NR could support a mode where the DCI in subframe n schedules an UL transmission in subframe A?+/ with k>0. It is then possible to schedule a future subframe to have 14 UL symbols.

  • the NR UE could not make any explicit assumption about the duplex direction of a subframe, but rather would consider a subframe as DL or UL depending on whether it has been scheduled for a PDSCH or PUSCH transmission, respectively. In that sense, such a design also follows the overall spirit of the NR with respect to forward compatibility where UE assumptions should be minimized to the extent possible.
  • ABS almost blank subframes
  • Fe ICIC inter-cell interference coordination
  • the X2AP defines two separate ABS pattern info bit strings of equal length, one that helps the eNB MAC scheduler in deciding the appropriate modulation and coding scheme (MCS) for a given subframe (including no transmission) and one that helps the eNB 102 RRC function to configure said measurement restrictions at the UE 1 12, for example.
  • MCS modulation and coding scheme
  • the LTE and NR networks could exchange information about the TDD UL/DL configuration— if such an interface is introduced— but there would be no need to signal them to NR UEs 1 12 or the like, for example. Rather such indication could be dynamic via the DCI.
  • LTE and NR networks should be able to coexist in the same spectrum.
  • LTE and NR could coexist as well as be multiplexed within the same carrier in either the time domain or frequency domain. Coexistence could be possible regardless of whether NR and LTE are controlled by the same base station and all LTE features can be supported in both paired and unpaired spectrum.

  • co-carrier networks e.g., the network 126 and 122
  • LTE and NR base stations could inform each other about time intervals of LTE and NR transmissions, respectively, such that the LTE network would activate the carrier when there are no NR transmissions and deactivate it whenever there are NR transmissions.
  • the time granularity of this approach could depend on whether ideal or non-ideal backhaul are assumed between the LTE and NR base stations / eNBs and the MAC level (de)activation procedure of LTE could also put a limit on the time granularity, i.e., subframe level coexistence may not be supported.
  • LTE Rel. 14 may introduce further enhanced lean SCells where subframe level coordination may be possible.

  • PSS primary synchronization signals
  • SSS secondary synchronization signals
  • NR and LTE resources are orthogonal and time-division multiplexed, both paired and unpaired spectrum can be supported.
  • NR and LTE networks could be on a subframe level or radio frame level.
  • a bitmap can indicate which subframes are reserved for LTE [NR] transmissions, respectively, whereas in the latter case, a bitmap can indicate which radio frame is reserved for LTE [NR] transmissions, respectively.
  • Other time granularities are not precluded.
  • the LTE and NR networks could be SFN aligned to align the bitmaps between each other.
  • the two networks could be controlled by the same scheduler. For example, when the same base station collocates LTE and NR cells, LTE and NR could be jointly scheduled. In fact, LTE and NR networks could even share the same FFT and RF front-end 1006 in the base station hardware if numerologies are aligned.
  • Rel. 8 UEs are not capable of carrier aggregation and cannot be configured with secondary cells, CA based techniques as above may not fully allow coexistence between NR and LTE with these UEs.
  • Rel. 8 UEs do, however, support MBSFN subframes.
  • NR transmissions could occur in the MBSFN region of an MBSFN subframe spanning 12 or 1 3 symbols depending on the LTE eNB antenna configuration and physical multicast channel (PMCH) configuration.

Sur la base de la transmission DL reçue, un signal toujours actif peut être configuré conformément à une reconfiguration des ressources réservées pour l'UE LTE et des systèmes de transmission avancés ou de nouvelles caractéristiques peuvent être ajoutées pour une nouvelle radio (NR) des UE sans interruption des dispositifs UE existants.
