  • An RRC parameter configures minimum duration D from the ending symbol of PUSCH to the starting symbol of DFI carrying feedback for that PUSCH.
  • the transmission resource is specified with a given periodicity with which the transmission resource repeats over the same frequency resources.
  • the transmission parameters such as HARQ process ID or redundancy version (RV) are not tied to any period of resource.
  • a UE selects the transmission parameters such as HARQ ID and RV according to the higher layer configuration.

  • a UE is configured to transmit multiple repetitions, and to transmit the repetitions over the subsequent periodic occasions after the transmission of the original transmission, thereby achieving a given reliability within the latency budget without additional overhead of multiple configured grant configurations.
  • AUE may start transmitting the packet in the first resource after the minimum processing time required for the UE to process the packet.
  • the apparatus, systems and methodsdescribed herein can be used to transmit traffic from more than one flow with different QoS requirements.
  • the generalized resources configured thus allow efficient handling of such flows with minimal control overhead. This also results in improved spectral efficiency. This provides a unified approach for both the licensed and unlicensed spectrums.
  • frequency hopping can be introduced for the periodic resources to exploit the frequency diversity to the advantage of high reliability.
  • Each period P maps to a HARQ ID through a deterministic known mapping, so the HARQ ID of a TB is determined by the HARQ ID of the period P in which the TB is transmitted. Thisintroduces severe limitations in the transmission of PUSCH repetitions.
  • a TB may not cross a CG period boundary, to prevent random packet arrival times that would otherwise require a large number of configurations and cause significant signalling overhead.
  • large number of CG configurations may be required by the current standards, resulting in large configuration and signalling overhead needed for activation and de-activation of such configurations.
  • Figure 2 illustrates the time frequency resources, shown by the dotted line boxes, configured for access by a UE.
  • the first packet arrives from the physical layer in sufficient time to be transmitted with 4 repetitions as per its configuration.
  • the 2 nd and the 3 rd packet get transmitted only with 3 and 2 repetitions respectively.
  • a UE is able to transmit 3 repetitions for the 2 nd packet in Figure 2.
  • the 3 rd packet arrives such that 2 repetitions in the current period can be made, as shown in Figure 2. This may not provide the target reliability for the transmission and degrade the quality of service.
  • the decoding may eventually succeed but there is a risk of violating the latency budget.
  • transmission resource configured for CG transmission are not available, for example due to the shared nature of the unlicensed spectrum, the subset of available resources may not be fully utilised due to limitations over TB restricted to period boundary. This will also require multiple CG configurations to transmit a suitable number of repetitions, wasting resources.
  • CG-UCI has been introduced in configured grant NR-U to avoid confusion between UE and the base station resulting from channel uncertainty.
  • explicit indication of control parameters is necessary over the licensed carriers to be able to identify transmission parameters such as HARQ ID and RV etc.
  • Thegeneralized configured grant scheme described herein provides a flexible framework, allowing the proposal of accommodating multiple traffic flows having different repetition requirements.
  • the time frequency resource is shown by dotted rectangle in each period P.
  • the period is not linked to the transport block, but to the resource repetition.
  • a UE is configured by the UL CG configuration to transmit 4 repetitions and starts transmitting the first transmission in the first available occasion, after the packet arrival at physical layer, after the minimum processing time, and transmits the configured number of repetitions in the subsequent resources.
  • Crossing period boundaries means that UE does not need to buffer the packet upon arrival in waiting for the next suitable interval like in legacy schemes, and explicit indication of CG-UCI leads to no confusion at the base station regarding the HARQ process transmitted and other relevant transmission parameters.
  • HARQ ID does not have a fixed mapping associated to resource period P.
  • the UE determines HARQ ID of a TB at the moment it is ready to transmit that TB and this HARQ ID is used for all repetitions of the TB in different periods.
  • a UE is configured to transmit with 4 repetitions and determines HARQ ID at the beginning of the transmission, which it then uses for all 4 repetitions in 4 different periods.
  • the HARQ-ID is communicated to the gNB by CG-UCI multiplexed with every PUSCH repetition so that the gNB can do proper combining for the TB decoding.
  • CG-UCI also contains RV, NDI corresponding to each PUSCH repetition.
  • transmission parameters such as HARQ ID and RV patterns are not associated to period but are instead selected in accordance with the higher layer configuration and are always transmitted and explicitly multiplexed over a transmitted PUSCH.
  • Thelegacyconfigured grant scheme accommodates unexpected packet arrival by having multiple configurations as shown in Figure 4, which illustrates 4 CG configurations. These configurations have staggered start times and a UE will choose the configuration closest to the packet arrival time and with sufficient number of repetitions available. The UE is able to transmit 4 repetitions for each of the three packets illustratedby selecting a different configuration for each of these packets. With large number of repetitions required, even more CG configurations may be required, resulting in larger control overhead and configuration delays.
  • FIG. 5 shows the behaviour of proposed scheme for the same packet arrivals at the gNB as for those transmitted by the method illustrated in figure 4, with a single proposed configuration capable of handling the arrival times of three arbitrary packet.
  • UE starts to transmit the packets in the first available occasion, and continues the repetitions in the subsequent resources up to the configured number of repetitions. This minimizes the latency without compromising the reliability for such transmissions. Additionally, the configuration is very simple and has minimal overhead.
  • the apparatus, systems and methods described herein can have two modes of configuration, going in line with Type 1 and Type 2 CG transmissions described in the standards.
  • Type 1 CG uses RRC configuration
  • Type 2 CG schemes require activation and de-activation transmitted in dynamic DCI based signalling.
  • the apparatus, systems and methods described herein can provide improved QoS and reduction on signalling overhead by configuring multiple (delayed) CG configurations to over the issues arising from random packet arrivals.
  • a single resource configuration, at a defined single time frequency resource with a defined periodicity, can accommodate different traffics with different number of repetitions.
  • Figure 6 shows the current approach required for a UE that needs two different configurations for two different repetitions numbers corresponding to different QoS, whichcan be configured as two CG configurations.
  • the figure shows Config1, which is configured with 2 repetitions and Config2, which is configured with 4 repetitions.
  • the use of multiple configurations may consume more resources and, for higher QoS requirements the two configurations illustrated in figure 6, may further require multiple staggered configurations to handle random packet arrival and/or channel uncertainty.
  • Figure 7 shows that the generalized scheme outlined herein, as a result of the association of periodicity to a single transmissionresource can handle both traffic types with a single configuration.
  • the configuration of such dual traffic aspect requires that the base station configures a multiple repetition number and relevant RV patterns as part of the CG configuration.
  • Another method to achieve this can be to configure a generalized CG periodic resource, and make this resource available in two different PUSCH configurations having different transmission parameters, such as number of repetitions.
  • the base station may miss a UE transmitting on a given CG occasion and therefore uses standardized DL feedback for UL CG based transmissions.
  • the apparatus, systems and methods described herein may employ downlink feedback with generalized configured grant transmissions, even for licensed carriers.
  • the configuration of generalized CG may include activation or de-activation of associated DL feedback. This provides a more flexible solution where feedback can be activated by the gNB when necessary in the light of the specific traffic QoS, the nature of the communication medium, and the cell dynamics.
