This has the advantage that it increases the data reliability in a more resource efficient manner compared to prior art reliability enhancing techniques which relies on higher layer packet duplication. Furthermore, it avoids queuing delays caused by unnecessary replicas of every packet.

  • the configured grant usage indicator can be configured to provide either implicit indication or explicit indication of the configured grant transmission opportunity usage.
  • An implicit indication of configured grant opportunity usage can be achieved by configuring an indicator timing offset relative to the configured grant opportunities. For example, a timing offset of 1 mini-slot means that the configured grant indicator is transmitted in 1 mini-slot after the configured grant opportunities.
  • An explicit indication means that the configured grant usage indicator is explicitly providing the needed information to identify the exact configured grant transmission opportunity by containing a gNB ID, configured grant ID and a timing offset indicator. The indicator can be configured to be only transmitted if at least one of the configured grant opportunities are used.
  • the configured grant usage indicator can be implemented in several ways. Two different examples are discussed in the following.
  • a new uplink control information (UCI) message format is introduced, for example, for transmission on the PUCCH.
  • the UE is then configured to use this UCI message format whenever a configured grant opportunity to the sNB is used.
  • the UE can, in this case, be configured in a similar manner as used for transmitting scheduling requests or periodic reference sequences on PUCCH and determine the resource allocation, for example, by relying on existing Release 15 UCI procedures.
  • the UE is configured with a special configured grant configuration to the mNB of similar periodicity as the configured grant configuration to the sNB.
  • a configured grant usage indicator message is simultaneously prepared by the UE and transmitted to the mNB according to the step 0 configuration.
  • the transmissions to the sNB and mNB are performed essentially at the same time thus meaning that the sNB is capable of receiving them about the same time and it is possible to associate the transmissions with each other. This can be performed even if the transmission are not sent and received exactly at the same time. Variable conditions and a transmission over mNB can always cause some deviations in receiving time.
  • the sNB attempts decoding 203 of the configured grant transmission.
  • a beam-misalignment In case of a beam-misalignment, it may not detect the transmission, and might interpret this occasion as a discontinuous transmission (believe that the UE did not transmit on the configured grant opportunity).
  • the mNB receives the configured grant usage indicator and forwards it rapidly to the sNB. If no configured grant usage indicator is received from the mNB, the gNB will follow the traditional behavior and assume that the UE skipped its transmission. Upon reception of the configured grant usage indicator, the sNB reacts accordingly. It may take the one of the following example actions, for example, depending on the urgency of the traffic.
  • sNB may trigger 204A a retransmission on dedicated resources from the UE to the sNB, possible with different transmission parameters and beam configuration. This can be a viable option if the latency requirement allows at least one retransmission and if the beam-misalignment is expected to be short and temporary.
  • sNB may request 204B the mNB to grant a retransmission to the UE, for example, the UE sending the data packet to the mNB, which then forwards this to the sNB.
  • the sNB can signal this to the mNB with the retransmission request, so it can grant the retransmission with proper parameters. This option is favorable in case the beam-misalignment with sNB is severe.
  • the latency requirement should allow the retransmission signal to be exchanged between mNB to gNB.
  • a possible extension to the second example is to configure the UE with a configured grant configuration to the mNB for data transmissions while the beam-misalignment is present.
  • the UE may chose not to use this configured grant configuration to the mNB anymore or the mNB can be instructed, by the sNB to release the configured grant configuration.
  • sNB may instruct 204C the UE to trigger a beam failure recovery request to start the beam failure recovery procedure early either by using sNB downlink or through the mNB.
  • Fig. 3a is a more detailed explanation of step 201A of figure 2.
  • the configured grant usage indicator is carried on a shadow configured grant configuration.
  • the mNB 301 receives from the sNB 300 the configured grant opportunities configured for the UE on the sNB 300 and calculates the equivalent configuration (shadow) for its own network parameters.
  • the mNB configures the UE with a shadow CG configuration (sCG).
  • the periodicity of the sCG in mNB 301 can be the same as the shortest periodicity of the CGs in sNB 300.
  • a sCG config of 1 symbol slot offset and 2 symbol periodicity is chosen.
  • the smallest TBS is chosen which is sufficient to carry 2 bits.
  • the UE calculates or is configured with the mapping of sNB CGs to sCG opportunities as described earlier.
  • a simple mapping rule is that all sNB CGs occurring between a sCG opportunity n and the previous sCG opportunity n-1 are put in the same indication message.
  • sNB CGI l -> CG opportunity 1
  • Fig. 4 is a more detailed explanation of step 201B of figure 2.
  • the mNB 401 receives the CG configurations from the sNB 400 and determines a suitable PUCCH configuration.
  • the UE may be configured with a number of sub-slots for PUCCH.
  • the UE calculates or is configured with the mapping of sNB 401 CGs to PUCCH sub-slots.
  • a simple rule is to select the sub-slot (or mini-slot) of which the sNB 401 CG falls into (similar to PDSCH to PUCCH mapping).
  • sub-slot 0 the PUCCH transmission in sub-slot 0 will be used for three sNB 401 CG opportunities.
  • the order is determined by the time of the sNB 401 CGs.
  • the CG usage indicator payload can be implemented several ways. In the following, three different examples are given. Firstly, a unique bitmap of sNB CG opportunities, as assumed for the examples above, may be used. Secondly, a unique bitmap per sNB symbol may be used. This is useful for large SCS differences between sNB and mNB. Thirdly, a counter of the number of transmitted CG may be used. This option is useful when the number of sNB CG is in one sCG opportunity or the UCI message is large. The sNB will be able to combine the knowledge of what was received and how many CG opportunities were available to attempt identifying which CG opportunities were lost. If latency constraint relaxed, the sNB can dynamic schedule a retransmission of the lost opportunities.
