  • Embodiments of the present system disclose methods and devices for achieving access for IAB so that both cellular access and backhaul access may be accomplished independently. In one embodiment, if access may not be achieved independently, the system may allow an operator to privilege backhaul traffic and access to the time frequency resources over the cellular access. In some examples of the Sharing Access Resources by Base Stations for both User Equipment and Backhaul Nodes embodiments, the following consideration may be made in order to achieve the independent access or privileged traffic:
  • the system may provide a method for controlling access to the IAB node of the mobile network by a User Equipment (UE), where only other IAB nodes are permitted to attach and connect.
  • UE User Equipment
  • a signal indicating that UEs need not attempt connection may be transmitted by using discovery information from the IAB on a broadcast channel (carried by Physical Broadcast Channel (PBCH)), where the broadcast channel is carrying information bit(s). That is, the UE may detect a synchronization signal while deciding which cell to camp on and the IAB may be signaling that an IAB node (or gNB cell) is corresponding to a backhaul cell and bar the UE from camping on the IAB node all together.
  • PBCH Physical Broadcast Channel
  • the IAB node may obtain the cell identity (Cell ID) and determine a set of parameters associated with the device sending the signal. That is, in some embodiments, the synchronization signal may comprise discovery information thereby the IAB may derive the Cell ID and location of the broadcast channel for the device sending the signal, to then determine the set of parameters.
  • the parent gNB may broadcast synchronization signal and broadcast channel to UE and the IAB child nodes.
  • the IAB child node may determine a Cell ID via the received synchronization signals which have been mapped to the Cell ID, and use the determined set of parameters transmitted and received, for broadcast attempt, to get into connected mode with the IAB parent node or gNB.
  • the discovery information in the SSB may differentiate which terminal device is authorized to connect to the network and therefore use the signal to bar UEs from connecting to the IAB.
  • the IAB may transmit a barring signal to the UE on the broadcast control channel within the network cell and set up, based on the barring signal, an access control to the service with regard to the UE by deciding whether a specific access request of the UE to the service is accepted or rejected.
  • the discovery information may be used to bar UE access for load balancing reasons. That is, using the broadcast channel-when Cell IDs are different-the signal may be used to bar UE access by determining whether it is a UE or IAB sending the signal through the lookup of parameters.
  • the parent gNB broadcasts synchronization signal on the broadcast channel to the UEs, so the timing of the transmission to IAB node and UE is aligned.
  • the Cell IDs may be received via a Random-Access Channel (RACH) which may be a shared channel used by wireless terminals to access the mobile network where RACH is on the transport-layer channel and the corresponding physical-layer channel is PRACH.
  • RACH Random-Access Channel
  • the parent gNB may transmit discovery information via the PBCH to IAB node and UE, where the IAB node and UE read the information. If the parent gNB indicates in the discovery information that the UE is barred from the cell due to load reason, then the UE has to find another cell to camp. While the IAB node can select that cell to camp, if the discovery information from PBCH allow it to do so. That is, there is a selection process allowing the discovery information on the synchronization signal to indicate whether a device may camp or not camp at the cell (IAB parent node or parent GNB). If the parent gNB doesn’t indicate the UE is barred from the cell in the discovery information, then the UE may continue to camp on the cell; where the PRACH procedures may then start to be implement in this scenario.
  • the Physical Random Access Channel is used by an uplink user to initiate contact with a base station.
  • the base station broadcasts some basic cell information, including where random-access requests can be transmitted.
  • a UE then makes a PRACH transmission asking for, for example, PUSCH allocations, and the base station uses the downlink control channel (PDCCH) to reply where the UE can transmit PUSCH.
  • PDCCH downlink control channel
  • the UE camps on the cell, if the UE wants any connection with the network, it will start PRACH procedures, thereafter, if the UE obtains PRACH resources successfully for PRACH preamble transmission, then the UE may have further communication with the network, until it successfully complete PRACH procedures and set up connection with the network. Otherwise the UE has to reselect PRACH resources to restart the PRACH procedures.
  • the system may prioritize the opportunity of backhaul to obtain PRACH resources successfully (if there are no conflicts with other IAB backhaul node and UEs).
  • An alternative embodiment consists of having a cell in which there is a single Cell ID for both cellular access and backhaul.
  • the set of PRACH resources specifically, the PRACH sequences, are partitioned into two sets, which may be configurable or be preconfigured and/or predefined by the network. One set is used for PRACH access for UEs, while the remainder of the set may be used for backhaul access for gNBs.
  • the parameter numberOfRA-PreamblesGroupBackIabhaul, or numberOfRA-PreamblesGroupIabUE can be configured, which defines the number of Random Access Preambles in Random Access Preamble group dedicated for IAB Backhaul use, or IAB UE use respectively.
  • Either numberOfRA-PreamblesGroupIabBackhaul, or numberOfRA-PreamblesGroupIabUE, or both of them can be configured by the network. For convenience, we call them numberOfRA-PreamblesGroupIabX.
  • numberOfRA-PreamblesGroupIabX can be for each synchronization signal/PBCH block (SSB), or for each cell, or for each IAB gNB/UE; if it is for each IAB gNB, which means all cells belonging to/associated with the IAB gNB share the preamble sequences defined by numberOfRA-PreamblesGroupIabX.
  • SSB synchronization signal/PBCH block
  • IAB gNB/UE if it is for each IAB gNB, which means all cells belonging to/associated with the IAB gNB share the preamble sequences defined by numberOfRA-PreamblesGroupIabX.
  • numberOfRA-PreamblesGroupA which defines the number of Random Access Preambles in Random Access Preamble group A for each SSB
  • Random Access Preambles group B is configured
  • numberOfRA-PreamblesGroupIabX is(are) for each SSB and configured
  • Alt 1> numberOfRA-PreamblesGroupIabX has nothing related to numberOfRA-PreamblesGroupA and numberOfRA-PreamblesGroupB, which means these two types of parameters are independently configured.
  • RA-PreamblesGroupIabX may, or may not, have overlap with RA-PreamblesGroupA/ RA-PreamblesGroupB.
  • numberOfRA-PreamblesGroupIabX is a subset of numberOfRA-PreamblesGroupA, or numberOfRA-PreamblesGroupB. For example, assuming totally there are 64 RA preamble sequences, and there are 48 RA preamble sequences (e.g., RA preamble sequence index from 0 to 47, or from 1 to 48) allocated to PreamblesGroupA, and 18 sequences are allocated to PreamblesGroupB.
  • numberOfRA-PreamblesGroupIabBackhaul can be a value not greater than numberOfRA-PreamblesGroupA, e.g., 40, which allows IAB backhaul to use preamble sequence index from 0 to 39, or from 1 to 40.
  • PreamblesGroupIabUE should be subset as well, e.g. when numberOfRA-PreamblesGroupIabUE is 10, IAB UE is allowed to use preamble sequence index from 40 to 49, or 41 to 50.
  • RA-PreamblesGroupIabX allows IAB gNB/UE to use preamble sequences with index mutual exclusive from PreamblesGroupA and PreamblesGroupB.
  • RA-PreamblesGroupIabX allows IAB gNB/UE to use preamble sequences with index 41 to 64 if the first 40 indexes are configured by the network to be used by PreamblesGroupA and PreamblesGroupB.
  • the number of available cyclic shifts available for RACH access may decline significantly.
  • the present embodiments include a mobile network infrastructure using 5G signals and 5G base stations (or cell stations).
  • an integrated access provides gNBs with coordination between gNBs in response to changing cellular and backhaul traffic states, therefore load balancing may be achieved by controlling access (e.g., access class baring) to network devices (e.g., UEs). Allowing the coordination of resources in response thereof may be via the Integrated Access and Backhaul topology comprising the transmission of discovery information between IAB-donors and IAB-nodes and IAB-donors and UEs, exchanged as part of the synchronization signals (if the network is not synchronized, SSB may be used for discovery instead).
  • modifying the coordination to allow limiting of resources that are requested by the UEs in the network due to backhaul traffic conditions may be implemented based on barring an access class associated with the UE, prioritizing use of resources based on needs of the wireless communication system and load management, and/or partitioning resources provided by the first base station based on the class of network equipment (terminal device).
