  • UL transmission is scheduled by the base station which uses a UL grant message to indicate a terminal which resource can be used for the next UL transmission.
  • This option is called grant based UL transmission.
  • grant free UL transmission or UL transmission without grant both mean the same thing.
  • UL transmission without grant a set of resources are pre-allocated to the terminal for a certain period and the UE can start its transmission without waiting for the downlink scheduling message. Both are illustrated in figure 1 (left: grant based; right: grant free) .
  • RTT Round Trip Time
  • SPS Semi-Persistent Scheduling
  • VoIP Voice over Internet Protocol
  • URLLC is considered to be useful for remotely controlling machines in a factory (factory control) in which the data packets arrive infrequently and sporadically. This may result in a large percentage of pre-allocated resources being wasted.
  • DMRS De-Modulation Reference Symbol
  • the HARQ process ID needs to be indicated to the gNB if more than one HARQ process is configured.
  • the gNB uses this information to put the received packet in the right buffer or if HARQ soft combining is required, the gNB uses this information to combine the right soft information to improve the reception performance.
  • RV Redundancy Version
  • K is the number of repetitions.
  • UE ID Hybrid Automatic repeater request (HARQ) process ID (HARQ PID in short below) and RV need to be indicated together with the UL grant free transmission. It is possible that parameters like time/frequency allocation, repetition number K, MCS and DMRS sequences, etc., could be (re-) configured by the gNB and according to current agreements, there will more flexible options than SPS in LTE for the gNB to modify parameters or to active/de-active a grant free connection.
  • RRC Radio Resource Control
  • DCI Downlink Control Information
  • DMRS for channel estimation (and possibly UE identification)
  • control signalling as discussed above
  • URLLC data for URLLC data.
  • URLLC Two requirements are identified for URLLC services: for URLLC the target for user plane latency should be 0.5ms for UL, and 0.5ms for DL; and URLLC reliability requirement is one transmission of a packet is 1-10 -5 for 32 bytes with a user plane latency of 1ms. Designs of all three parts, i.e., DMRS, control signalling and data, are still open. The URLLC requirements for each part could be supported separately. DMRS pattern and density may to be designed to maximize the overall link performance. Control signalling needs to be the most reliable part as it has no HARQ protection and its one-short detection reliability must be no less than 1-10 -5 . It should be noted that UE ID, HARQ PID and RV may have different reliability requirements. The data part has HARQ protection so its one-short detection reliability reduced as far as the final reliability of 1-10 -5 can be achieved with HARQ retransmission.
  • DMRS is considered to indicate UE ID
  • specific DMRS sequence can be configured to a UE and the gNB can identify the UE by detecting the corresponding DMRS sequence. It may be possible to extend this option to let DMRS further support HARQ PID and/or RV. In that case, multiple DMRS sequences may need to be configured to a UE.
  • This option may have a detection reliability problems especially when the resources are multiplexed with enhanced Mobile Broadband (eMBB) UEs. Due to power control of the multiplexed eMBB UE, the interference at the gNB could be very different and the gNB may need to select a threshold with the worst case for the detection which will in return reduce the DMRS detection reliability.
  • eMBB enhanced Mobile Broadband
  • the eMBB modulated symbols may be correlated to the URLLC DMRS symbols and in such a case, a false alarm may be produced. Due to these drawbacks, it is assumed that it is even harder for DRMS to indicate HARQ PID and/or RV.
  • different HARQ processes may be mapped to different time/frequency resources. Multiple resources may be pre-allocated to a UE, and the UE selects the resource with the HARQ process ID for the transmission.
  • This option may be possible to extend this option to let different resource indicate RV as well.
  • This option requires multiple resources are pre-allocated. On one hand, this may further decrease the resource usage efficiency, and on another hand, it may not support many HARQ processes in the frequency domain as URLLC services normally require a wide band. It may further increase the latency when multiple resources are allocated in the time domain as discussed in the example given below with reference to figure 2.
  • mini-slot #0 3 HARQ processes are mapped to three mini-slot sets, i.e., mini-slot #0, 3, 6... for HARQ PID #0, mini-slot #1, 4, 7... for HARQ PID #1 and mini-slot #2, 5, 8... for HARQ PID #2.
  • Buffer #0 must be transmitted with HARQ PID #0
  • the UE cannot transmit it in the first available mini-slot (#4 in this example) and has to skip two mini-slots until mini-slot #6. This introduces an additional latency of two mini-slots.
  • HARQ PID to UL Control Information be introduced, which can be transmitted together with UL data. It may be possible to extend this option to include RV.
  • This option requires the introduction of a new type of UCI. This new type of UCI has a different reliability requirement from others and more standardization efforts are required.

  • the invention include three main attributes.
  • RV and HARQ PID By jointly encoding RV and HARQ PID, the overall size of UL signalling can be minimized and accordingly less UL resources will be consumed and the reliability of UL data transmission can be improved.
  • piggybacking the UCI on PUSCH the resource allocation of UL grant free transmission can be simplified and no dedicated resources need to be allocated for signalling. Piggybacking can also help to reduce the out-band emissions by supporting continuous resources usage.
  • a false alarm rate of DMRS detection By adding a secondary UE ID, a false alarm rate of DMRS detection can be reduced and it may enhance the UE identification reliability for URLLC transmissions.
  • RVs and HARQ processes required for URLLC and for eMBB is open for discussion, but is likely to include eight HARQ processes for very high throughputs.

  • the two sets of resources are configured to the UE, e.g., two 10MHz sub-bands of 20MHz band.
  • the value of this bit is indicated by whichever set of resources is used for transmission.
  • the second bit is carried by whichever DMRS sequence is used and two sequences are configured to the UE so both sequences can be used to identify this UE. Simultaneously, the value of this bit can be indicate by selecting the corresponding sequence.
  • the remaining two bits (third and fourth) are carried in UCI.
  • UCI for grant free transmission could be carried out in a similar way to LTE.
  • One way is to use a piggyback with PUSCH and the other way is to be carried in PUCCH.
  • the option to use piggyback with PUSCH is detailed below and forms part of the present invention.
  • RRC or DCI signalling It is assumed that all configurations mentioned above are indicated to the UE via RRC or DCI signalling.
  • One example is for the gNB to allocate a number of different resource sets, a number of DMRS sequences and a number of UCI bits. Different resources are used in a pre-defined order to carry the jointly encoded bits.
  • the number of RVs and the number HARQ processes are also indicated via RRC and/or L1 signalling.
  • modulated DMRS symbols are first mapped to predefined Resource Block (RB) positions.
  • Encoded and modulated UCI symbols are mapped to certain RB positions to insure a better link performance.
  • the best positions for UCI are those around the DMRS and encoded and modulated UCI symbols function mapped to these positions has better results.
  • Encoded and modulated data symbols are mapped to all the remaining RB positions.
  • each RB position includes 12 subcarriers in the frequency domain and 1 symbol in the time domain.
  • a different RB size might be defined, e.g., a resource block of 12 subcarriers by 2 symbols or subcarriers of a RB could be multiplexed between DMRS, UCI and data even if the same RB size is used. For example, 6 subcarriers for UCI and the remaining 6 subcarriers for data. See the symbol scheme of figure 5 by way of example.
  • the UCI may have a fixed payload size and the modulation order could be fixed too, e.g., Quadrature Phase Shift Keying (QPSK) .
  • QPSK Quadrature Phase Shift Keying
  • Normally rate matching is used when the amount of physical resources is not fixed, or the physical resources are fixed but the payload size is not fixed.
  • its payload size could be fixed and it is mapped to the physical resources with a higher priority so there is less need to do rate matching.
  • the modulation order of data symbol may be indicated by downlink control signalling, either RRC or DCI. Note, it is assumed the CP-OFDM waveform is used in the figure4 scheme and if the DFT-s-OFDM waveform is used, all 3 parts (DMRS, UCI and data) may be mapped to the physical layer in the time domain.
  • part or full UE ID is included in the UCI to improve the reliability of DMRS detection
  • Pattern #0 has 1 OFDM symbol fully used for DMRS so the DMRS density equals 1/2.
  • Pattern #1 has one RB used for DMRS from every two in the first OFDM symbol and all RBs in the second symbol are used for data so the DMRS density equals 1/4.
  • Pattern #2 has one RB from every 3 RBs used for DMRS in the first symbol and Pattern #3 and Pattern #4 have one RB from every 4 and 5 RBs separately used for DMRS with corresponding DMRS density equals 1/8 and 1/10 respectively.
  • TBCC Tail-biting Convolutional Codes
  • LTE PUCCH like rate matching is used, modulated with QPSK and then mapped to the remaining RBs of 10 MHz bandwidth except those used for DMRS.
  • Rate matching is applied accordingly for each DMRS pattern which means a lower coding rate with lower DMRS density and a high coding rate with higher DMRS density.
  • DMRS density needs to be selected with a trade-off between channel estimation and data resources.
  • the optimal DMRS density could be different for 15 KHz, 30 KHz and 60 KHz SCS and may be evaluated separately.
  • the DMRS detection is based on a threshold and this threshold is selected with a trade-off between false alarm rate (FAR) and detection rate.
  • FAR false alarm rate
  • False alarm rate is the probability of detection when nothing is actually transmitted by a UE, a false alarm will result in resource waste for both downlink control channel and uplink data channel, and 1%threshold might be an acceptable value.
  • the cross correlation value is normalized by the power of the second symbol. It is observed that different DMRS patterns do not have a significant difference in detection performance
  • the detection probability can be improved from 99.97x%to 99.999%with the cost of the false alarm rate being increased from 1%to 1.7x%.
  • the secondary UE ID could be a segment of the normal UE ID, e.g., Cell Radio Network Temporary Identity (C-RNTI) , or a completely different one which is used to verify the validity of the one detected from DMRS sequence if applicable.
  • C-RNTI Cell Radio Network Temporary Identity
  • the number of secondary UE ID bits included in the UCI is selected according the need to reduce the FAR.
  • the actual FAR from DMRS detection is related to the DMRS density and vender specific algorithm, so the number of secondary UE ID bits to be included in the UCI needs to be aligned between the gNB and the UE.
  • the actual secondary UE ID bits could be obtained from a number of different processes. For example, explicit signalling from the gNB, in which the gNB can indicate in the RRC the number of secondary UE ID bits and the corresponding values. Alternatively implicitly from other configured parameters, for instance, the last few bits of C-RNTI assigned by the gNB, or a set of bits pre-determined for the assigned DMRS sequence. In another example, the number of secondary UE ID bits could be signalled by the gNB but their values are implicitly obtained. This can be summarize as the following three options: size and value are both signalled by the gNB; size and value are both implicitly obtained from other configured parameters; and size is signalled by the gNB, and the actual value is obtained from other configured parameters.
  • UE #i uses DMRS sequence #i
  • a secondary UE ID of 2 bits are included in the UCI to reduce the FAR and a UE can be identified by DMRS sequence #i + a dedicated value of the partial UE ID.
  • UE #i uses DMRS sequence #i, a secondary UE ID of 1 bit is included in the UCI to reduce the FAR (every two UEs have the same partial UE ID) and each UE can be identified by DMRS sequence #i + a dedicated value of the partial UE ID.
  • all UEs use the same DMRS sequence and each UE is identified only by a dedicated value of the partial UE ID.
  • some UEs could share the same DMRS sequence and each UE can be identified by DMRS sequence index + a dedicated value of the partial UE ID.
  • the secondary UE ID can be either signalled by the gNB via RRC and/or L1 signalling or obtained from a pre-defined mapping with the DMRS sequence when possible, for instance, in Example #1, the secondary UE ID is the last two bits of the DMRS sequence index.
  • Table 4 The various combinations are shown in table 4.
  • the simulation has not considered multiple DMRS sequences and when there are multiple cross correlator peaks from any correlator with only noise or interference input will trigger a false alarm so the false alarm rate will be increased. It is expected that with N cross correlators, the false alarm rate will be N times higher.
  • the UE may transmit DMRS, UCI and data without grant.
  • the DMRS sequence may be pre-configured by the gNB, and UCI may include a number of secondary UE ID bits, RV and/or HARQ PID.
  • the data part may be encoded and modulated with an MCS which is also pre-configured by the gNB.
  • FIG 8 An example processing procedure is illustrated in figure 8 for the gNB side.
  • the gNB first identifies a UE by detecting the corresponding DMRS sequence and the peak of multiple cross correlators’outputs is selected and compared against a threshold. If the peak is above the threshold, a UE is assumed to be temporally identified and after the UCI is decoded, this temporal UE ID is verified by the secondary UE ID bit or bits from the UCI. If both match, the gNB will assume a real transmission is detected otherwise it will assume no UL transmission. If the detected UE ID and the secondary UE ID bits match, the receiver can further use the modulated UCI symbols to improve the channel estimation and as a result, the link performance of the data part can be further improved.

It will be appreciated that the present invention may equally apply to other types of transmission in other environments.
