  • AP access point
  • UE user equipments
  • Radio access wide area or enterprise
  • the AP of the sub-network serves and manages the sub-network devices on one hand and is connected to a gNB of the radio access network on the other hand. Therefore, the AP of the sub-network represents a sort of special UE within the radio access network.

  • the deployment in 6G of these “small mobile supporting life critical applications” sub-networks poses many new challenges from the air interface design to the architectural enablers.
  • One main challenge is the management of interferences among neighboring sub-networks that need to be properly handled.
  • Fig. 1B illustrates an example environment of 3 sub-networks connected to a same network device in some embodiments of the present disclosure.
  • Fig. 1B there are 3 access points of sub-networks connected to a same gNB of a radio access network.

  • the radio access gNB may have a whole picture of the interference conditions experiences by all the sub-networks, and thus CRS has large potential to achieve much better performance when compared to distributed resource selection (DRS) , which needs anyhow to be in place when sub-networks go out-of-coverage.
  • DRS distributed resource selection
  • An enabling technical component for provisioning of extreme performance requirements is the sub-band channelization of the carrier, i.e., the carrier bandwidth is divided into multiple sub-bands and each sub-network operates in one (or more) sub-band to provide extreme connections.
  • the CRS is essentially the issue of which sub-bands need to be allocated to each sub-network based on the information available at the gNB.
  • the AP of sub-network feedback to the gNB is a challenge.
  • each sub-network may serve several tens of UEs: it would be too much overhead for the AP to send back all the UE measurements to the gNB. Besides the large overhead, this type of massive feedback may not even be needed for some use cases. For in-vehicle, such detailed information inside a vehicle shared outside may not be desired for security reasons. Furthermore, short term feedback on the interference is useful to allow opportunistic use of resources. However, if this short term feedback needs to be provided to the gNB, then the utility of this information is reduced due to the latency associated with this feedback.
  • Sub-networks cover small areas, and therefore there will be correlation among the power levels of the received signal and interference as measured by two nearby devices in most of the cases. Feedback of all the measurements is simply not efficient. On other hand, there may be large difference in signal and interference levels among nearby devices in some specific scenarios, for example in the in-vehicle case between sensors/UEs inside and outside the car frame.
  • the feedback format sent back to the gNB should fulfill the following conditions: being a per group of UEs feedback rather than a per-UE feedback; describing the interference experienced in the geographical area covered by the sub-network or a part of the sub-network; being flexible enough to capture different properties among the sub-networks in terms of occupied areas or number of devices. Even for the in-vehicle case, cars can have very different dimensions as produced by different manufacturers.
  • a network device for a radio access network transmits, to an access point of a sub-network associated with the radio access network, a request for information on support for a report associated with interference variability among transmission links within the sub-network. Then the network device receives, from the access point, a response comprising the information indicating at least one first parameter for the network device to determine a configuration of the report. Based on the at least one first parameter, the network device determines the configuration indicating at least one second parameter to be comprised in the report. Moreover, the network device transmits the configuration of the report to the access point.
  • This solution provides a mechanism to enable the AP of the sub-network to report back to the network device some information about the interference situation experienced within the coverage area of the sub-network.
  • This information about the interference includes both information on the inter-sub-network interference as well as intra-sub-network interference.
  • the inter-sub-network interference means that the communication in the sub-network can be degraded due to external interference, and that has been recognized as one of the main challenges for sub-network operations. Then the inter-sub-network interference information can be used by the gNB to decide to move the full sub-network to another set of resources where the external interference is not as severe.
  • a too high intra-sub-network interference means that the number of resources allocated for the sub-network communications are too few, and in this case the gNB should evaluate if additional resources need to be allocated.
  • the solution proposes that the AP of the sub-network provides a feedback to the gNB made by following two components: interference measurement report (IMR) and Interference variability report (IVR) .

  • the number of transmission links not meeting the at least one communication service requirement within the sub-network (K S ) represents the number of transmission links experiencing average SINR conditions below that threshold.
  • interference can be very uncorrelated among UEs, therefore some UEs experience an interference largely deviating from the average reported in the IMR.
  • the SINR includes both inter-sub-network and intra-sub-network interference.
  • the presence of intra-sub-network interference means that transmissions within the sub-network are not scheduled on orthogonal resources in time and/or frequency, thus calling for additional resources to be assigned by the gNB to that sub-network.

Un dispositif réseau pour un réseau d'accès radio transmet, à un point d'accès d'un sous-réseau associé au réseau d'accès radio, une demande d'informations sur la prise en charge d'un rapport associé à une variabilité d'interférence entre les liaisons de transmission au sein du sous-réseau. Le dispositif réseau reçoit, du point d'accès, une réponse comprenant les informations indiquant au moins un premier paramètre pour que le dispositif réseau détermine une configuration du rapport. D'après le(s) premier(s) paramètre(s), le dispositif réseau détermine la configuration indiquant au moins un second paramètre à inclure dans le rapport. De plus, le dispositif réseau transmet la configuration du rapport au point d'accès.
