In the following, unless explicitly stated otherwise, both frequency-domain resources and time-domain resources will be used as examples of transmission resources to describe some exemplary embodiments of this disclosure. It should be noted that the exemplary embodiments of this disclosure are equally applicable to other resources in other domains.

[0034] As mentioned above, resource allocation within a subnet is susceptible to interference from other subnets. One approach is to allocate subbands based on interference measurement and monitoring. Outside of coverage areas, interference issues can be addressed through distributed resource allocation. In distributed resource allocation, resource allocation can be performed autonomously within the subnet.

[0035] While subband allocation (or general resource allocation) requires an understanding of inter-subnet interference, it remains unclear how to account for the heterogeneity of service requirements between subnets during subband allocation. Given the pervasive association between subnet technologies and licensed frequency band access (such as 6G), leveraging specific tools to improve resource allocation based on service requirements holds significant potential.

[0036] Many concepts developed for subband resource allocation follow principles similar to unlicensed band access (such as Wi-Fi) and attempt to benefit from centralized approaches to avoid excessive interference between subnets. However, these methods are often difficult to adapt to unlicensed band access. They do not utilize inter-subnet communication methods and priorities when accessing subbands. Regardless of whether centralized or distributed resource allocation is used, components can be specified for licensed band access. In other words, while distributed resource access in unlicensed bands does not consider the importance of underlying services and operates primarily on a first-come, first-served basis, service requirements can be considered when allocating resources in licensed band access.

[0037] Subband allocation within licensed frequency bands offers significant advantages over unlicensed frequency band technologies in terms of how resources are coordinated between nodes and subbands. Specifically, nodes can use specified metrics and channels to transmit these metrics, prioritizing channel access among them; this applies to both centralized and distributed resource allocation scenarios.

[0038] The exemplary embodiments of this disclosure provide a solution for resource allocation within a subnet. In this solution, a priority metric for a target subnet is determined based on at least one service requirement to be satisfied within the target subnet. Resource allocation for multiple subnets is determined based on the respective priority metrics of the subnets.

[0039] This solution can prioritize resource access in subband, time slot, and / or spatial transmission directions based on service requirements, such as the Quality of Service (QoS) requirements of services within the subnet. For example, in the allocation of resources (e.g., subband) in heterogeneous subnets, the QoS or Quality of Experience (QoE) requirements of subnet devices can be considered.

[0040] As mentioned above, existing subnet frequency subband allocation methods do not fully consider the criticality of services within the subnet. The proposed solution can address the priority issue of 6G subnet frequency resource access based on the QoS requirements of devices within the subnet. In this way, subnet resource allocation can be more efficient and effective.

[0041] Figure 1 An example communication environment 100 in which example embodiments of the present disclosure may be implemented is illustrated.

[0042] The communication environment 100 includes multiple subnets 110-1, 110-2, 110-3, ..., 110-N. In each subnet, first devices 120-1, 120-2, 120-3, ..., 120-N, such as APs, can communicate with multiple devices 130-1, 130-2, ..., 130-M (such as sensors, actuators, mobile phones, etc.). N and M represent positive integers. For the purposes of discussion, subnets 110-1, 110-2, ..., 110-N can be referred to individually or collectively as (multiple) subnets 110, first devices 120-1, 120-2, ..., 120-N can be referred to individually or collectively as (multiple) first devices 120, and devices 130-1, 130-2, ..., 130-N in subnets 110-1, 110-2, ..., 110-M can be referred to individually or collectively as (multiple) devices 130.

[0043] Subnet 110 can be an in-X subnet. Figures 2A to 2D The diagram illustrates example in-X subnets in robotic or production, vehicle-mounted, in-body, or internal subnets. In these embodiments, APs 205, 210, 215, and 220 are used as... Figure 1 The example of the first device 110 is operated. Figure 2A As shown, sensors and actuators can be used in the robot / production module subnet 200A. In Figure 2B In the vehicle subnet 200B, sensors and actuators can be embedded in the trunk, ignition system, safety devices, engine, or suspension within the vehicle 225. Subnets 200A and 200B can have high performance requirements in terms of reliability (up to six nines or more) and latency (as low as 100µs or even lower), for example, challenging periodic and deterministic communication services in 6G systems.

[0044] like Figure 2C As shown, the pacemaker 230 and some tactile sensors / actuators can be deployed within the in vivo subnet 200C. Figure 2D As shown, some internal devices (such as virtual reality (VR) glasses 230) can be deployed within the internal subnet 200D.

[0045] Still referencing Figure 1 Services with different time-critical levels can be transmitted within subnet 110, which may include high time-critical services (<<1ms), medium time-critical services (1~10ms), and / or non-critical services, such as Key Performance Indicator (KPI) monitoring. Services may have different service requirements, such as QoS or QoE requirements.

[0046] Outside of subnet 110, the first device 120 can be connected to a second device 140 in a wide area network (WAN), such as a base station (BS) or xNB, which can control and coordinate subnet 110. Services between the first device 120 and the second device 140 may include medium-time critical services and / or non-critical services.

[0047] Communication in communication environment 100 can be implemented according to any suitable communication protocol(s), including but not limited to cellular communication protocols such as first-generation (1G), second-generation (2G), third-generation (3G), fourth-generation (4G), fifth-generation (5G), and sixth-generation (6G), wireless local area network communication protocols such as IEEE 802.11, and / or any other protocols currently known or to be developed in the future. Furthermore, communication can utilize any suitable wireless communication technology, including but not limited to: Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Frequency Division Duplex (FDD), Time Division Duplex (TDD), Multiple-Input Multiple-Output (MIMO), Orthogonal Frequency Division Multiplexing (OFDM), Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM), and / or any other technologies currently known or to be developed in the future.

[0048] It should be understood that Figure 1 The number and type of devices shown are for illustrative purposes only and do not represent any limitation. Communication environment 100 may include any suitable number and type of devices and apparatus. For example, more than one first device may be deployed in a subnet, and one of these first devices may operate as a serving AP.

[0049] In the following description, for illustrative purposes, some example embodiments are described in which the first device 110 operates as an access point (AP) and the second device 120 operates as a network base station (BS). However, in some example implementations, the operations described in conjunction with network devices (e.g., AP or BS) may be implemented at terminal devices or other devices.

[0050] In the communication environment 100, the second device 140 can allocate resources to multiple subnets 110-1, ..., 110-N based on the corresponding priority metrics of the subnets. In some example embodiments, the first device 120-1 can combine the service request metrics of devices 130-1, ..., 130-M in subnet 110-1 into a priority metric for subnet 110-1. According to some example embodiments of this disclosure, when allocating resources to subnet 110, the priority metric of subnet 110 can be considered, which may depend on the service requests of devices 130 within subnet 110.

[0051] In some example embodiments, subnets 110-1, ..., 110-N can be divided into three groups for resource (e.g., subband) allocation based on corresponding priority metrics, including, for example, subnet 110-1 with a high priority metric for priority centralized resource allocation (RA); subnet 110-2 with an intermediate priority metric for centralized RA; and subnet 110-N with a low priority metric for distributed RA.

[0052] In this way, subnet priority metrics (e.g., determined by the QoS requirements of device services) can be fully considered and embedded in the resource allocation process. See below for reference. Figure 3 and Figure 4 Describe some example implementations.

[0053] Figure 3 This is a signaling diagram illustrating an example communication process 300 between a first device 120 and a second device 140 according to some example embodiments of the present disclosure. As described in detail in the following paragraphs, the first device 120 may operate as a first device 120-1, ..., 120-N in different use cases.

[0054] like Figure 3 As shown, in process 300, the first device 120 (e.g., the first device 120-1) determines (315) the priority metric (e.g., designated P1) of the target subnet 110 (e.g., subnet 110-1) based on the corresponding service requirements (designated as SD1, ..., SDM) to be met by each device (e.g., each device 130-1, ..., 130-M) within the target subnet (e.g., subnet 110-1) of the plurality of subnets 110-1 to 110-N. The priority metric for the target subnet can be merged by the first device 120 based on the priority metric or service requirements (e.g., designated as SD1, ..., SDM) of the devices 130-1, ..., 130-M within the target subnet 110-1.

[0055] In some example embodiments, the first device 120 may determine a corresponding priority metric (designated as PT1, ..., PTM) for each device in at least one device (e.g., devices 130-1, ..., 130-M) in the target subnet 110 based on the corresponding service requirements corresponding to each device in the target subnet 110-1. Then, the first device 120 may determine a priority metric for the target subnet based on the corresponding priority metric for each corresponding device 130-1, ..., 130-M in the target subnet 110-1.

[0056] In one example, the first device 120 may calculate a priority metric based on the QoS requirements of each device 130 (or each user), for example, using a formula, a lookup table, or any other method. For instance, the priority metric for each device 130-1, 130-2, ..., 130-M within subnet 120-1 may be calculated as the reciprocal of the required latency value, weighted by the negative logarithm of the reliability requirements of devices 130-1, 130-2, ..., 130-M, to base 10. For example, a reliability requirement of 10^-5 for device 130-1 at a 1ms latency may be converted to a priority metric of 5000 (i.e., 5 / 0.001). A reliability requirement of 10^-6 for device 130-2 at a 2ms latency may be converted to a priority metric of 3000 (i.e., 6 / 0.002). A reliability requirement of 10^-9 for device 130-M at a 10ms latency may be converted to a priority metric of 900. As another example, each QoS level may be mapped to a specified priority index. Mapping can be predefined, fixed, or hard-coded in the 3GPP standard, or it can be pre-configured or configured by the network.

[0057] Based on the priority metrics of devices 130-1, ..., 130-M within subnet 120-1, the first device 120-1 can calculate the priority metric of subnet 120-1. For example, the maximum or median of the priority metrics of devices 130-1, ..., 130-M can be determined as the priority metric of subnet 120-1. Other algorithms can also be applied when calculating the priority metric of subnet 120-1 based on the priority metrics of devices 130-1, ..., 130-M.

[0058] In some example embodiments, the algorithms or methods(s) used to merge priority metrics of subnet 110 may be network-configurable. For example, second device 140 may transmit (305) a configuration (referred to as a second configuration, designated CB) for determining (315) the priority metrics of target subnet 110 to first device 120. The second configuration may include algorithms or methods for merging priority metrics of target subnet 110. The second configuration may also include algorithms or methods for determining the corresponding priority metrics of each device 130-1 to 130M within target subnet 110-1. The second configurations (designated CB1, ..., CB2) associated with different subnets 110-1, ..., 110-N may be the same or different.

[0059] Accordingly, the first device 120 may receive (310) the second configuration from the second device 140. Then, the first device 120 may determine (315) a priority metric for the target subnet 110 based on the second configuration according to the corresponding service requirements to be met by each device 130-1, ..., 130-M within the target subnet 110-1.

[0060] The second configuration can be transmitted (305) from the second device 140 to the first device 120 at any suitable time and with any suitable signaling. In one example, the first device 120 can receive (315) the second configuration from the second device 140 when connected to an overlay network or WAN (network). In this way, for example, when connected to an overlay or WAN network, the overlay or WAN network can inform subnet 110 of the algorithms or methods(s) used to merge priority metrics for subnet 110.

[0061] After determining (315) the priority metric of the target subnet 110, the first device 120 transmits (320) the priority metric of the target subnet 110 to the second device 140. For example, the first device 120 (e.g., an AP) in subnet 110 can feed back the priority metric of subnet 110 to the second device 140, such as a WAN BS (or xNB).

[0062] Accordingly, the second device 140 receives (325) the priority metric of the target subnet 110 from the first device 120. In addition, the second device 140 can receive priority metrics of other subnets from other first devices 120 in the subnet.

[0063] Then, the second device 140 determines (330) the corresponding resource allocation types (designated as T1, ..., TN) of the multiple subnets 110-1, ..., 110-N based on the corresponding priority metrics (P1, ..., PN). The resource allocation type may include centralized resource allocation (designated as CR). In centralized resource allocation, the second device 140 may allocate resources (e.g., designated as R1) for the target subnet (e.g., subnet 110-1). Alternatively or additionally, the resource allocation type may include distributed resource allocation (designated as DR). In distributed resource allocation, the first device 120 may autonomously select resources (e.g., designated as RN) for the target subnet (e.g., subnet 110-N).

[0064] The second device 140 transmits (335) multiple first configurations (designated as CA1, ..., CAN) for resource allocation of multiple subnets 110-1, ..., 110-N to multiple first devices 120-1, ..., 120-N. Accordingly, the first device 120 receives (340) at least one first configuration (e.g., CA1) for resource allocation of a target subnet 110-1 from the second device 140. The first configuration may include configurations related to resource allocation corresponding to the target subnet. In some example embodiments, at least one first configuration for resource allocation may include an indication of the resource allocation type (e.g., T1) of the target subnet 110-1. In some example embodiments, the first configuration for resource allocation of a subnet subject to centralized resource allocation may include configurations of resources allocated to the subnet.

[0065] In some example embodiments, resource allocation for some subnets 110 can be prioritized based on priority metrics. In one example, if a set of subnets (e.g., subnets 110-1 to 110-3) in a plurality of subnets 110-1, ..., 110-N (referred to as the first set) has a higher priority metric, for example, if the corresponding priority metric of each subnet in the first set is greater than or equal to a threshold priority metric (referred to as the first threshold priority metric, designated THP1), then the second device 140 can determine a centralized resource allocation for the first set of subnets. The first threshold priority metric can be set according to the network deployment or actual service requirements of the plurality of subnets 110-1, ..., 110-N. If the corresponding priority metric of each subnet in the second set of subnets (e.g., subnet 110-N) is lower than the first threshold priority metric, then the second device 140 can determine a distributed resource allocation for the second set of subnets.

[0066] In this way, the second device 140 can centrally allocate resources (designated as R1, R2, and R3) of subnets 110-1 to 110-3 with higher priority metrics. Therefore, during resource allocation, the service requirements of subnets 110-1 to 110-3 can be given priority to ensure that they are met.

[0067] In some example implementations, resource allocation to a subnet can be based on the interference that subnets exert on each other. This interference can depend on the relative positions of devices within the subnet. The stronger the interference between subnets, the more "orthogonal" their resource allocation will be.

[0068] Interference can be measured by a first set of devices (e.g., first devices 120-1 to 120-3) within a first subnet set (e.g., subnets 110-1 to 110-3) based on reference signals from the first subnet set transmitted from the second device 140 to the first set of devices, and at least one third configuration (CC). The third configuration can indicate the reference signal for each subnet in the first subnet set. The reference signals of different subnets can be orthogonal to each other. The third configuration received by the first device 120-1 can indicate the reference signal for subnet 110-1, as well as the reference signals for other subnets 110-2 and 110-3. Third configurations transmitted to more than one subnet can contain the same information related to the reference signals and interference measurements of all subnets in the first subnet set.

[0069] For example, after the first device 120-1 in the target subnet 110-1 receives reference signals and at least one third configuration of measurements from the second device 140 for the first subnet set 110-1 to 110-3, the first device 120-1 can perform at least one measurement on at least one interference of at least one remaining subnet 110-2 and 110-3 in the first subnet set to the target subnet 110-1. Then, the first device 120-1 can transmit the measurement result of at least one interference to the second device 140.

[0070] The second device 140 can receive corresponding measurements of interference between a first set of first devices (e.g., first devices 120-1 to 120-3) and a first set of subnets (e.g., subnets 110-1 to 110-3). Based on the corresponding measurements of interference, the second device 140 can allocate resources for the first subnets. Resources may include subbands, time slots, and / or spatial transmission directions. In some example embodiments, a first configuration of resource allocation transmitted (335) by the second device 140 to the first subnets may include an indication of the resources allocated for the first subnets.

[0071] In some example embodiments, the first subnet set can be further divided into different subnet subsets with different resource allocation priorities. In one example, if the corresponding priority metric of each subnet in the subset of subnets (e.g., subnet 110-1) within the first subnet set (referred to as the first subset) is greater than or equal to a threshold priority metric (referred to as the second threshold priority metric, designated THP2) that is higher than the first threshold priority metric, then the second device 140 can determine a first centralized resource allocation (designated CR1) for the first subnet subset. The first subnet subset with a priority metric higher than the second threshold priority metric can have high requirements. The second threshold priority metric can be set according to the network deployment or actual service requirements of multiple subnets 110-1, ..., 110-N.

[0072] If the corresponding priority metric of each subnet in a subset (referred to as the second subset) of subnets (e.g., subnets 110-2 and 110-3) within the first subnet set (e.g., subnets 110-1 to 110-3) is greater than or equal to a first threshold priority metric and lower than a second threshold priority metric, then the second device 140 may determine a second centralized resource allocation (designated CR2) for the second subnet subset. The first centralized resource allocation may take precedence over the second centralized resource allocation.

[0073] For example, the second device 140 can use a centralized RA to configure mutually orthogonal reference signals (RS) and RS measurements of the first subnet sets 110-1 to 110-3 to obtain information about inter-subnet interference. For the first subnet sets 110-1 to 110-3, reference signal transmission can be performed by the first set 120-1 to 120-3 of the first devices within the subnet according to a third configuration, and related measurements can be performed by devices in each subnet and reported to the associated first set 120-1 to 120-3 of the second devices, and then the first set of the first devices feeds back the measurement results to the second device 140. For example, one or more devices of the first device 120-1 in the first subnet 110-1 can measure the received power of reference signals transmitted from other first devices 120-2 and 120-3 in other subnets 110-2 and 110-3. Based on the measured power of the reference signals, the inter-subnet interference level can be obtained and fed back as a measurement result to the second device 140.

[0074] The second device 140 can perform (or conduct) centralized RA for the first subnet sets 110-1 to 110-3 based on the acquired measurement results and the priority metrics of the first subnet sets 110-1 to 110-3. For example, the first subnet sets 110-1 to 110-3 with centralized RA can be divided into two subsets (or two parts): a first subnet subset 110-1 (or the first part of the subnet) with a priority metric higher than a second threshold priority metric (e.g., having a high requirement); and second subnet subsets 110-2 and 110-3 (or the second part of the subnet).

[0075] For a first subnet subset (e.g., subnet 110-1) within a first subnet set (e.g., subnets 110-1 to 110-3), the second device 140 can allocate resources sequentially in descending order of the corresponding priority metrics of the subnets within the first subnet subset. In some example embodiments, a resource list can be maintained for each subnet in the first subnet set (e.g., subnets 110-1 to 110-3). For example, the second device 140 can initialize a resource list with all available resources (e.g., all subbands) for each subnet in the first subnet set 110-1 to 110-3. Such a resource list can also be referred to as a resource whitelist.

[0076] The second device 140 can select resources from the resource list (i.e., resource whitelist) of the first subnet 110-1 in the first subnet subset. The first subnet may have a first priority metric. If the second subnet 110-2 in the first subnet set (e.g., subnets 110-1 to 110-3) has a second priority metric lower than the first priority metric, and the interference from the second subnet 110-2 is higher than a threshold interference (which may be referred to as a third threshold interference, designated THI3), then the second device 140 can remove the resources allocated to the first subnet 110-1 from the resource whitelist of the second subnet 110-2. The value of the third threshold interference can be set according to the network deployment or actual service requirements of multiple subnets 110-1, ..., 110-N. For example, the third threshold interference can be lower for subnets with higher performance requirements. In this way, interference to subnets with higher priority metrics can be avoided through resource allocation.

[0077] For example, for each subnet in Part 1 (e.g., subnet 110-1) and Part 2 (110-2 and 110-3), the second device 140 can initialize a subband whitelist (as an example of a resource whitelist) using all subbands (as an example of a resource whitelist). For Part 1 subnets, the second device 140 can sequentially allocate subbands to each subnet 110-1 in descending order of priority metric from its subband whitelist. The allocated subbands can be randomly selected from the subband whitelist. Alternatively or additionally, previous resource allocations can be considered. For example, subbands already allocated to a subnet may not be selected or may be allocated to other subnets.

[0078] After a subband (e.g., subband-a) is assigned to subnet 110-1, based on the interference information between subnets, for any (part 1 or part 2) subnet 110-2 or 110-3 whose interference to subnet 110-1 is higher than the third threshold interference, subband-a can be removed from the subband whitelist of subnet 110-2 or 110-3.

[0079] In some example embodiments, resources allocated to a first subnet subset (or a first part of the subnet, such as subnet 110-1 to 110-3) within a first subnet set (e.g., subnets 110-1 to 110-3) can form a resource set (referred to as the first set) (designated RS1), which may also be referred to as the first protected resource set. For example, subbands allocated to the first part of the subnet can form a subband set, referred to as the first protected subband set.

[0080] For a second subnet subset (or a second part of the subnet, such as subnets 110-2 and 110-3) within a first subnet set (e.g., subnets 110-1 to 110-3) whose priority metric is greater than or equal to a first threshold priority metric and lower than a higher second threshold priority metric, the second device 140 may allocate resources to reduce interference between the second subnet subsets.

[0081] In one example, in an embodiment where resources include subbands, for second subnets 110-2 and 110-3, the second device 140 can perform (or conduct) centralized subband allocation based on their respective subband whitelists, for example using the Sequential Iterative Subband Allocation (SISA) algorithm, under subband whitelist constraints. Using the SISA algorithm, the second device 140 can sequentially perform subband allocation for second subnets 110-2 and 110-3. For example, subband allocation can be performed first for subnet 110-2. Subbands can be selected for subnet 110-2 from its subband whitelist, minimizing the total perceived interference between second subnets 110-2 and 110-3. Subband allocation can then be performed for subnet 110-3 in a similar manner. Subband allocation is performed iteratively on subnets 110-2 and 110-3 in the second part, thereby iteratively updating the subbands allocated to subnets 110-2 and 110-3 to minimize interference between these subnets 110-2 and 110-3.

[0082] In some example embodiments, resources allocated to a second subnet subset (or a second part of the subnets, such as subnets 110-2 and 110-3) within a first subnet set (e.g., subnets 110-1 to 110-3) can form a resource set (referred to as the second set) (designated RS2), which may also be called the second protected resource set. For example, subbands allocated to the second part of the subnets can form a subband set, referred to as the second protected subband set.

[0083] For a second subnet set (e.g., subnet 110-N) having distributed resource allocation due to a priority metric lower than the first threshold priority metric, the first configuration of the resource allocation (335) transmitted by the second device 140 may include at least one configuration (designated as RD) of the distributed resource allocation to the second subnet set (e.g., subnet 110-N) of the second set of the first devices (e.g., first device 120-N). The at least one configuration of the distributed resource allocation may include information regarding at least one of the first resource set allocated to a first subnet subset (e.g., subnet 110-1) within the first subnet set (e.g., subnet 110-1 to 110-3) or a second resource set allocated to a second subnet subset (e.g., subnets 110-2 and 110-3) within the first subnet set. The same configuration of the distributed resource allocation may be transmitted to more than one subnet constrained by the distributed resource allocation.

[0084] In some example embodiments, at least one configuration of distributed resource allocation may include a time window (specified as TW) for distributed resource allocation. After the time window is configured, distributed resource allocation can be performed on subnets (e.g., subnet 110-N) within the configured time window to improve interference management.

[0085] After receiving at least one configuration for distributed resource allocation, the first device 120 (e.g., first device 120-N) can accordingly select resources for the target subnet (e.g., subnet 110-N). In some example embodiments, the first device 120 can select resources outside the first and second resource sets indicated by at least one configuration for distributed resource allocation to avoid interference with subnets with higher priority metrics. In some example embodiments, the selected resources can be outside the first resource set, allowing the first resource set to be highly protected.

[0086] In some example embodiments, the first resource set can be reused to improve resource efficiency. In some example embodiments, if the interference to resources in the first resource set is below a threshold interference (referred to as the first threshold interference, denoted as THI1), the first device 120 can select resources for the target subnet 110. In this way, interference to subnets with higher priority metrics can be reduced.

[0087] In some example embodiments, a second resource set can be reused to further improve resource efficiency. In some example embodiments, if the interference to resources in the second resource set is below a threshold interference (referred to as the second threshold interference, denoted as THI2), the first device 120 can select resources for the target subnet 110. The second threshold interference of the second resource set can be higher than the first threshold interference of the first resource set, so that the first resource set is highly protected.

[0088] The following describes an example RA process. In this example, it is assumed that there can be eight subnets (e.g., N=8), denoted by subNW-n, where n=1, 2, ..., 8. Additionally, there can be four subbands, denoted by subband k, where k=1, 2, 3, 4. A second device 140, such as a WAN BS, can acquire the priority metrics of all eight subnets. Based on the subnet priority metrics, the second device 140 can determine that subNW-6, subNW-7, and subNW-8 are distributed RA subnets because their priority metrics are below a first threshold priority metric, while the other subnets (subNW-n, n=1, 2, 3, 4, 5) are centralized RA subnets because their priority metrics are above the first threshold priority metric.

[0089] Interference information between centralized RA subnets is obtained from the internet interference matrix through reference signal transmission and inter-subnet interference measurement.W This is represented as follows:

[0090] Here, the rows and columns correspond to sub-NW-1 to sub-NW-5, respectively. "na" indicates unavailable. It should be noted that in the interference matrix W, the measured interference is scaled to the range of 0 to 1, with larger values ​​indicating more severe interference.

[0091] Based on the subnet priority metric, the five subnets can be divided into two parts: Part 1, which includes subnets NW-2 and NW-3, has a priority metric higher than the second threshold priority metric, indicating that they have top-level extreme performance requirements; and Part 2, which includes the other subnets, namely subnets NW-1, NW-4, and NW-5. For each of the five subnets, a subband whitelist can be initialized to include all four available subbands, namely {sb1, sb2, sb3, sb4}.

[0092] During the subband allocation process for the first subnet (subNW2 and subNW3), it is assumed that the priority metric for subNW-2 is higher than that for subNW-3. For subNW-2, the second device 140 can randomly allocate a subband from its subband whitelist. For example, subband sb1 is allocated to subNW-2.

[0093] In this example, the third threshold interference can be 0.20. The interference from sub-NW-4 and sub-NW-5 to sub-NW-2 is higher than the third threshold interference. Therefore, subband sb1 assigned to sub-NW-2 is removed from the corresponding subband whitelists of sub-NW-4 and sub-NW-5. That is, the subband whitelists of sub-NW-4 and 5 are updated to {sb2, sb3, sb4}. The subband whitelists of the other sub-NWs remain unchanged.

[0094] Then, for sub-NW-3, its current subband whitelist includes all subbands. Considering the previous assignment (to sub-NW-2), subband sb2 can be assigned to sub-NW-3. Since the interference from sub-NW-1 and sub-NW-5 to sub-NW-3 exceeds the third threshold interference of 0.20, subband sb2 can be removed from the corresponding subband whitelists of sub-NW-1 and sub-NW-5. That is, the subband whitelist of sub-NW-1 is updated to {sb1, sb3, sb4}. The subband whitelist of sub-NW-5 is updated to {sb3, sb4}.

[0095] The current whitelists for sub-bands NW-1, NW-4, and NW-5 are as follows: Sub-NW-1: {sb1, sb3, sb4}, Sub-NW-4: {sb2, sb3, sb4}, and Sub-NW-5: {sb3, sb4}.

[0096] Based on the subband allocation of the first part of the subnet, the first protected subband set can be determined as {sb1, sb2}.

[0097] During the subband allocation process of the second subnet (sub-NW-1 / 4 / 5), centralized subband allocation can be performed on the second subnet based on its subband whitelist, for example, using the SISA algorithm under the constraint of the subband whitelist. For example, in each iteration of the subnet, the subband to be allocated can be selected from the subnet's subband whitelist (instead of all available subbands).

[0098] Furthermore, by considering the priority metrics of these subnets, the interference measurement matrices of the remaining subnets NW-1 / 4 / 5 can be further updated. W For example, interference matrix W Priority metrics can be used to create matrices that can be used in the SISA algorithm. W In one example, this is achieved by calculating the priority metric for each sub-NW and... W Create by the product of the corresponding rows W Each row. In this example, the remaining two subbands {sb3, sb4} are assigned to the second part of the subnet. Based on this, the second protected subband set is determined to be {sb3, sb4}.

[0099] The second device 140 can transmit the configuration of the distributed RA to a subnet having the distributed RA. The configuration may include information about protected subband sets (i.e., the first protected subband set {sb1, sb2} and the second protected subband set {sb3, sb4}) and the time window of the distributed RA.

[0100] Distributed subband allocation can be performed on these subnets based on the configuration received from the second device 140. In one example, subbands belonging to the first protected subband set may not be selected. Alternatively, subbands in that set may be selected only if the sensed interference on the subband is below a first threshold interference. Alternatively or additionally, subbands in the second protected subband set may be selected only if the sensed interference on the subband is below a second threshold interference.

[0101] In this way, subnets are divided into three groups for resource or subband allocation: subnets with higher priority metrics (e.g., above the second threshold priority metric) based on a subband whitelist-based centralized RA are allocated subbands called the first protected subband set; subnets with medium priority metrics (e.g., between the first and second threshold priority metrics) in a centralized RA, for example, using an iterative algorithm SISA updated with subband whitelists, are allocated subbands called the second protected subband set; and subnets with lower priority metrics (e.g., below the first threshold priority metric) in a distributed RA that considers both the first and second protected subband sets are allocated subnets. Therefore, resource allocation can be performed more efficiently and effectively by fully considering the subnet's priority metrics (e.g., determined by the QoS requirements of the device's services).

[0102] Figure 4 An example process 400 for resource allocation of a subnet according to some example embodiments of the present disclosure is illustrated. In this example, WAN BS 405 can be used as... Figure 1 The second device 140 is an example of the AP 410. The AP 410 can be operated as an example of the first device 120 within a subnet 110 with a centralized RA, and the AP 415 can be operated as an example of the first device 120 within a subnet 110 with a distributed RA.

[0103] like Figure 4 As shown, in step 0, WAN BS 405 can transmit configurations (420, 422) to APs 410 and 415 on the subnet. These configurations can instruct APs 410 or 415 on how to combine service request metrics of devices in the subnet into subnet priority metrics (which may be referred to as subnet priority metrics). For example, WAN BS 405 can notify APs 410 and 415 when connecting to the WAN network.

[0104] In step 1, APs 410 and 415 can calculate priority metrics (424, 426) based on the QoS requirements of each user or device within the subnet, for example, using formulas or lookup tables, such as based on specified or pre-configured methods. In step 2, APs 410 and 415 can feed back the subnet priority metrics (428, 430) to WAN BS 405.

[0105] In step 3, based on the received subnet-specific priority metric, WAN BS 405 can determine (432) the resource allocation (RA) type for all subnets and the configuration of reference signals and measurements for subnets with priority metrics higher than a first threshold priority metric. The RA type mentioned can be a centralized RA or a distributed RA. In a centralized RA, WAN BS 405 allocates resources (or subbands) to the subnet. In a distributed RA, AP 410 or 415 autonomously selects resources for the subnet according to constraints indicated by WAN BS 405. The configuration of reference signals and measurements can be used for centralized RA subnets (with priority metrics higher than a first threshold priority metric). WAN BS 405 can indicate (434, 436) the RA type to AP 410 and 415. In some example embodiments, WAN BS 405 can indicate (434) the configuration of RS and measurements to AP 410.

[0106] In step 4, AP 410 within the subnet with centralized RA (also known as the centralized RA subnet) can perform (438) reference signal transmission and related measurements according to its configuration, and then feed back (440) the measurement results to WAN BS 405. In step 5, WAN BS 405 can perform (442) centralized RA for the subnet based on the acquired measurement results (in step 4) and the subnet priority metric (in step 2). The centralized RA subnet can be divided into two parts: a first part of the subnet with a priority metric higher than the second threshold priority metric (i.e., with high requirements); and the other subnets as the second part of the subnet.

[0107] For each of the Part 1 / Part 2 subnets, the WAN BS 405 can initialize a subband whitelist with all subbands. For Part 1 subnets, the WAN BS 405 can sequentially allocate subbands to each subnet from its subband whitelist in descending order of priority metric. The allocated subbands can be randomly selected from the subband whitelist or considered based on previous allocations. After allocating subbands to subnets, based on interference information between subnets (obtained in step 4), for any subnet (Part 1 or Part 2) where interference to that subnet exceeds a third threshold, the allocated subband can be removed from its subband whitelist. The subbands allocated to the Part 1 subnets form a subband set, referred to as the first protected subband set.

[0108] For the second subnet, WAN BS 405 can perform centralized subband allocation based on its corresponding subband whitelist, for example, using the SISA algorithm, and update it with subband whitelist constraints. The subbands allocated to the second subnet form a subband set, called the second protected subband set.

[0109] In step 6, the WAN BS 405 may transmit (444) the configuration of the distributed RA to the AP 410 within the subnet with the distributed RA (also referred to as the distributed RA subnet). The configuration may include a set of protected subbands, including a first protected subband set and / or a second protected subband set. The first protected subband set includes subbands requiring high protection. For example, subbands belonging to the first protected subband set may not be selected for the distributed RA subnet. Instead, subbands in this set may be selected only if the sensed interference on the subband is below a first threshold interference. The second protected subband set includes subbands requiring protection. For example, subbands belonging to the second protected subband set may be selected for the distributed RA subnet only if the sensed interference on the subband is below a second threshold interference. The first and second threshold interferences may also be included in the distributed RA configuration. The configuration may also include a time window allowing distributed subband allocation.

[0110] In step 7, AP 415 can perform (446) distributed subband allocation on the distributed RA subnet based on the configuration shown in step 6.

[0111] Figure 5 A flowchart of an example method 500 implemented at a first device according to some example embodiments of the present disclosure is shown. For discussion purposes, it can be seen from... Figure 1 The first device 120 in the method of angle description 500.

[0112] At box 510, the first device 120 determines a priority metric for the target subnet based on the corresponding service requirements that each device in the target subnet from multiple subnets needs to meet.

[0113] At frame 520, the first device 120 transmits a priority metric for the target subnet to the second device 140.

[0114] At frame 530, the first device 120 receives from the second device 140 at least one first configuration of resource allocation corresponding to the target subnet.

[0115] In some example embodiments, the first device 120 may receive from the second device 140 a second configuration for determining a priority metric for a target subnet. In some example embodiments, the priority metric for the target subnet may be determined based on this configuration according to the corresponding service requirements that each device within the target subnet needs to meet.

[0116] In some example embodiments, the first device 120 may determine a corresponding priority metric for each of at least one device in the target subnet based on the corresponding service requirements of each device in the target subnet. The first device 120 may determine the priority metric for the target subnet based on the corresponding priority metric corresponding to each corresponding device in the target subnet.

[0117] In some example embodiments, at least one first configuration of resource allocation may include an indication of the resource allocation type for the target subnet.

[0118] In some example embodiments, the resource allocation type may include at least one of centralized resource allocation or distributed resource allocation. The second device 140 may allocate resources for the target subnet in a centralized resource allocation. The first device 120 may autonomously select resources for the target subnet in a distributed resource allocation.

[0119] In some example embodiments, the first device 120 may receive reference signals and at least one third configuration of measurements for a first subnet set from the second device 140. The corresponding priority metric for each subnet in the first subnet set may be greater than or equal to a first threshold priority metric. The first device 120 may perform at least one measurement on at least one interference of at least one remaining subnet in the first subnet set to a target subnet based on the reference signals and at least one third configuration of measurements. The first device 120 may transmit the measurement result of at least one interference to the second device 140.

[0120] In some example embodiments, at least one first configuration of resource allocation may include an indication of resources allocated for a target subnet.

[0121] In some example embodiments, at least one first configuration for resource allocation may include at least one configuration for distributed resource allocation. In some example embodiments, the first device 120 may select resources for a target subnet based on at least one configuration for distributed resource allocation.

[0122] In some example embodiments, at least one configuration for distributed resource allocation may include information about at least one of the following: a first resource set, a second resource set, or a time window for distributed resource allocation, wherein the first resource set is allocated to a first subnet subset within a first subnet set, and the second resource set is allocated to a second subnet subset within the first subnet set. The corresponding priority metric for each subnet in the second subnet subset may be greater than or equal to a first threshold priority metric and lower than a higher second threshold priority metric. The corresponding priority metric for each subnet in the first subnet subset may be greater than or equal to a second threshold priority metric.

[0123] In some example implementations, the resources of the target subnet may be outside the first resource set.

[0124] In some example embodiments, the first device 120 may select resources for a target subnet from a first resource set based on the interference to the resources being below a first threshold interference.

[0125] In some example embodiments, the first device 120 may select resources of a target subnet from a second resource set based on the interference to the resources being below a second threshold interference.

[0126] In some example embodiments, resources may include subbands, time slots, and / or spatial transmission directions.

[0127] Figure 6 A flowchart of an example method 600 implemented at a second device according to some example embodiments of the present disclosure is shown. For the purposes of discussion, method 600 can be described from the perspective of the second device 140 in FIG2.

[0128] At frame 610, the second device 140 receives corresponding priority metrics for multiple subnets 110 from multiple first devices 120.

[0129] At box 620, the second device 140 determines the corresponding resource allocation type of the multiple subnets 110 based on the corresponding priority metrics of the multiple subnets 110.

[0130] At frame 630, the second device 140 transmits multiple first configurations of resource allocation for multiple subnets 110 to multiple first devices 120.

[0131] In some example embodiments, the second device 140 may transmit multiple second configurations to multiple first devices 120 for determining corresponding priority metrics for multiple subnets.

[0132] In some example embodiments, multiple first configurations of resource allocation may include indications of corresponding resource allocation types for multiple subnets.

[0133] In some example embodiments, the resource allocation type may include at least one of centralized resource allocation or distributed resource allocation. The second device 140 may allocate resources to subnets within a plurality of subnets in a centralized resource allocation. The first device among the plurality of first devices 120 may autonomously select resources for subnets within a plurality of subnets in a distributed resource allocation.

[0134] In some example embodiments, if the corresponding priority metric of each subnet in the first subnet set is greater than or equal to a first threshold priority metric, the second device 140 can determine a centralized resource allocation for the first subnet set among a plurality of subnets.

[0135] In some example embodiments, if the corresponding priority metric of each subnet in the first subnet subset of the first subnet set is greater than or equal to a higher second threshold priority metric, then the second device 140 can determine a first centralized resource allocation for the first subnet subset.

[0136] In some example embodiments, if the corresponding priority metric of each subnet in the second subnet subset of the first subnet set is greater than or equal to a first threshold priority metric and lower than a second threshold priority metric, then the second device 140 may determine a second centralized resource allocation for the second subnet subset. The first centralized resource allocation may take precedence over the second centralized resource allocation.

[0137] In some example embodiments, the second device 140 may transmit reference signals and at least one third configuration of measurements for a first subnet set to a first set of the first devices among a plurality of first devices. The second device 140 may receive corresponding measurements of interference between the first subnet sets from the first set of first devices.
