Title: Determining available capacity per cell partition

Description:
TECHNICAL FIELD 
     Particular embodiments relate to wireless communication, and more specifically to determining available capacity per cell partition. 
     BACKGROUND 
     Generally, all terms used herein are to be interpreted according to their ordinary meaning in the relevant technical field, unless a different meaning is clearly given and/or is implied from the context in which it is used. All references to a/an/the element, apparatus, component, means, step, etc. are to be interpreted openly as referring to at least one instance of the element, apparatus, component, means, step, etc., unless explicitly stated otherwise. The steps of any methods disclosed herein do not have to be performed in the exact order disclosed, unless a step is explicitly described as following or preceding another step and/or where it is implicit that a step must follow or precede another step. Any feature of any of the embodiments disclosed herein may be applied to any other embodiment, wherever appropriate. Likewise, any advantage of any of the embodiments may apply to any other embodiments, and vice versa. Other objectives, features, and advantages of the enclosed embodiments will be apparent from the following description. 
     In Third Generation Partnership Project (3GPP) fifth generation (5G) new radio (NR) wireless networks, a radio cell may transmit multiple synchronization signals (SS) and physical broadcast channel (PBCH) blocks (SSB) for cell search and synchronization, An SSB consists of a primary and secondary synchronization signals (PSS, SSS), each occupying 1 symbol and 127 subcarriers, and a PBCH signal spanning across 3 orthogonal frequency division multiplexing (OFDM) symbols and 240 subcarriers, with one symbol having an unused part in the middle for SSS. 
     The sub-carrier spacing determines the possible time locations of SSBs within a half-frame. The network configures the periodicity of the half-frames where SSBs are transmitted. During a half-frame, the network may transmit different SSBs in different spatial directions (e.g., using different spatial beams spanning the coverage area of a cell). 
     Multiple SSBs may be transmitted within the frequency span of a carrier. The physical cell identifiers (Pas) of SSBs transmitted in different frequency locations are not necessarily unique, but different SSBs in the frequency domain can have different PCIs. When an SSB is associated with a remaining minimum system information (RMSI), however, the SSB corresponds to an individual cell, which has a unique NR cell global identity (NCO). Such an SSB is referred to as a cell-defining SSB (CD-SSB). A PCell is always associated to one and only one CD-SSB located on the synchronization raster. 
     Because a network may transmit SSB beams to cover different parts of the cell&#39;s coverage area, and from a user equipment (UE) perspective measurement reports are based on detection of such SSBs, it is possible to divide the cell in SSB coverage areas and to determine parameters such as load, composite capacity, and resource status information for each partition of the cell. With this approach, SSB measurement reports from a UE enable the network to assess which portion of the cell the UE is located and the resource status information for that partition of the NR cell. This provides a significantly finer granularity than in long term evolution (LTE) where resource status information is available at a per cell level. An example is illustrated in  FIG. 1 . 
       FIG. 1  is a block diagram illustrating resource utilization for multiple cells. As illustrated, gNB 1  controls a serving cell with a plurality of UEs, and gNB 2  controls two cells, Cell-A and Cell-B, Each of the ovals represents a particular beam. The illustrated load distribution is unbalanced between SSB within an NR cell and can benefit from mobility load balancing (MLB) to the coverage area of SSB with low load. 
     Using resource status information per SSB beam can be beneficial for enhancing MLB in NR. The illustrated NR serving cell (gNB 1 ) is highly loaded at least in some local area defined, for instance, by the coverage area of different SSB beams. A target UE in the loaded area may report measurements that a neighbor Cell-A is detected with good radio conditions, possibly including beam measurements, and also reports another cell that is farther away e.g. Cell-B. 
     Using the LTE MLB solution as a baseline for NR, the serving node can request resource status information from the target node. The resource status information may indicate a high load in Cell-A. A high load may be at least the same number of UEs and same traffic as the serving node is experiencing. If only cell-specific resource status information is available, the loaded serving node may be led to believe that the target node is also overloaded. With SSB-beam specific resource status information available, however, the serving cell can determine that, in the beam coverage area where the UE is moving. Cell-A has enough available capacity to accept the UE. 
     LTE defines the cell composite available capacity to indicate the overall available resource level in a cell in either downlink or uplink. The composite available capacity (CAC) is defined as (see IS 32.522): Composite Available Capacity=Cell Capacity Class Value*Capacity Value. The Cell Capacity Class Value (CCCV) indicates the value that classifies the cell capacity with regards to the other cells. The Cell Capacity Class Value information element (IE) only indicates resources that are configured for traffic purposes and it is expressed with an integer ranging from 1, indicating the minimum cell capacity, to 100 indicating the maximum cell capacity, following a linear relation between cell capacity and the Cell Capacity Class Value as described in TS 36.331. 
     In TS 36.423, the cell capacity class value is an optional parameter in case of intra-LTE load balancing. If cell capacity class value is not present, then IS 36.423 assumes that bandwidth should be used instead to assess the capacity. The Capacity Value (CV) indicates the amount of resources that are available relative to the total evolved universal terrestrial radio access network (E-UTRAN) resources. The capacity value should be measured and reported so that the minimum E-UTRAN resource usage of existing services is resented according to implementation. The Capacity Value IE ranges between 0, indicating no available capacity, and 100 which indicates maximum available capacity. Capacity Value should be measured on a linear scale. 
     There currently exist certain challenges. For example, a cell-specific CAC as defined in LIE has at least two shortcomings. For multiple input multiple output (MIMO) transmission capability, a cell-specific CAC may incorrectly represent the cell available capacity. Furthermore, a cell specific CAC value does not provide any information about the distribution of the cell load or available capacity in the spatial domain. The latter aspect is important to optimize the network operation in case of advance antenna systems capable of MIMO transmission with narrow beams, like in the 3GPP NR system or LIE system with massive NEMO antenna array. An example is illustrated in  FIGS. 2A and 2B . 
       FIGS. 2A and 2B  illustrates cell resource availability for a cell with MIMO capabilities. The illustrated example includes LTE cell-specific CAC used for characterizing the available capacity in a radio cell capable of spatial multiplexing users via MIMO transmission and assumes CCCV=100 and 4 SSSB beams.  FIG. 2A  illustrates how resources are used to serve UEs under the coverage area of each of the SSB beams.  FIG. 2B  illustrates how resources are utilized from the cell perspective: 
       FIG. 2A  illustrates light traffic scheduled under the coverage area of all SSB beams. In particular, the cell schedules: (a) users within the coverage area of SSB 1  only in 40% of the resources; (h) users within the coverage area of SSB 2  only in 20% of the resources; (c) users within the coverage area of SSB 3  only in 20% of the resources; and (d) users within the coverage area of SSB 4  only in 40% of the resources. 
     With MIMO transmission capabilities, the available capacity under the coverage area of each SSB beam may range between 60% and 80%. Therefore, the cell overall appears lightly loaded and could accept more users/traffic under the coverage area of all SSB beams. 
     Using a cell-specific CAC as defined in the LTE system, however, only 30% of the capacity appears available (i.e., CAC=3000 out of a CAC_max=10000). In other words, the cell is considered highly loaded. A similar conclusion can be drawn if defining the available capacity for a traffic slice. 
     SUMMARY 
     As described above, certain challenges currently exist with determining composite available capacity (CAC) for a cell. Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges. 
     For example, particular embodiments determine the available capacity in different regions of the coverage area of a radio cell, as well as the overall cell capacity as a function of the capacity available in different regions of the cell&#39;s coverage area. 
     A particular embodiment includes a method executed by a first network node. The method comprises: computing the available capacity associated to one or more partitions of a radio cell; computing the available capacity associate to the radio cell based on the available capacity associated to one or more partitions of the radio cell; and transmitting a resource status information message to a second network node comprising the available capacity associated with one or more partitions of the radio cell and/or the available capacity associated to the radio cell. 
     In particular embodiments, a partition of a radio cell is represented by any one of the following: (a) the coverage area of reference signal beams, e.g. SSB beams; (h) a network slice; and/or (c) a network slice and the coverage area of a reference signal beam. 
     In some embodiments, a method executed by a first network node comprises: computing the available capacity associated to the coverage area of one or more reference signal spatial beams transmitted within a radio cell; computing the available capacity associated to the radio cell based on the available capacity associated to the coverage area of reference signal spatial beams transmitted in the radio cell; and transmitting a resource status information message to a second network node comprising the available capacity associated to the coverage area of one or more spatial beams transmitted within a radio cell and/or the available capacity associated to the radio cell, According to some embodiments, a method performed by a network node for determining available capacity comprises determining an available capacity of one or more partitions of a radio cell and transmitting a resource status information message to another network node. The resource status information message comprises at least one of the determined available capacities of the one or more partitions of the radio cell. 
     In particular embodiments, the method further comprises determining an available cell capacity for the radio cell based on the determined available capacity of the one or more partitions of the radio cell. The resource status information includes the available cell capacity for the radio cell. 
     In particular embodiments, determining the available capacity of one or more partitions of the radio cell is based on all cell resources being available to each of the one or more partitions of the radio cell. 
     For example, the available capacity of a partition of the radio cell may be a composite available capacity comprising a partition capacity class value and a partition capacity value wherein the partition capacity class value is equal to a cell capacity class value, and the partition capacity value is an amount of resources available within the partition relative to the partition capacity class value. 
     In particular embodiments, determining the available capacity of one or more partitions of the radio cell is based on a fraction of cell resources being available to each of the one or more partitions of the radio cell. 
     For example, the available capacity of a partition of the radio cell may be a composite available capacity comprising a partition capacity class value and a partition capacity value wherein the partition capacity class value is smaller than a cell capacity class value and the sum of the partition capacity class value of all partitions equals the cell capacity class value, and the partition capacity value is the amount of resources available within the partition relative to the partition capacity class value. 
     As another example, the available capacity of a partition of the radio cell may be a composite available capacity comprising a partition capacity class value and a partition capacity value wherein the partition capacity class value is smaller than a cell capacity class value and the sum of the partition capacity class value of all partitions exceeds the cell capacity class value, and the partition capacity value is the amount of resources available within the partition relative to the partition capacity class value. 
     In particular embodiments, determining the available cell capacity for the radio cell comprises averaging each of the available capacities of the one or more partitions of the radio cell. 
     In particular embodiments, the one or more partitions of the radio cell comprise coverage areas of one or more reference signal beams. The one or more reference signal beams may comprise one or more synchronization signal blocks (SSBs) beams. The one or more partitions of the radio cell may comprise one or more network slices, or the one or more partitions of the radio cell comprise one or more network slices and coverage areas of one or more reference signal beams. 
     According to some embodiments, a network node comprises processing circuitry operable to perform any of the network node methods described above. 
     Also disclosed is a computer program product comprising a non-transitory computer readable medium storing computer readable program code, the computer readable program code operable, when executed by processing circuitry to perform any of the methods performed by the network node described above. 
     Certain embodiments may provide one or more of the following technical advantages. For example, particular embodiments facilitate determination of an estimate of the available capacity in different regions of the coverage area of a radio cell capable of MEMO transmission. This can enable more efficient mobility related decisions in the system and more efficient load balancing and load sharing among radio cells, thus resulting in an overall better spectral efficiency and system performance.

     DETAILED DESCRIPTION 
     As described above, certain challenges currently exist with determining composite available capacity (CAC) for a cell. Certain aspects of the present disclosure and their embodiments may provide solutions to these or other challenges. 
     Particular embodiments are described more fully with reference to the accompanying drawings. Other embodiments, however, are contained within the scope of the subject matter disclosed herein, the disclosed subject matter should not be construed as limited to only the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art. 
     Particular embodiments include capacity associated to coverage area of downlink reference signals beams. A partition of the radio cell may be represented by the coverage area associated to a downlink reference signal transmitted in a region of the cell&#39;s coverage area. In one example, the downlink reference signal is a synchronization signal (SS) and physical broadcast channel (PBCH) Blocks (SSB) transmitted in a predefined spatial direction using, for example, multiple-input multiple-output (MIMO) beamforming techniques. For ease of reference, this will be referred to as the coverage area of an SSB beam, or more generally the coverage area of a downlink reference signal beam. 
     In particular embodiments, the available capacity associated to the coverage area of a downlink reference signal beam is determined as Beam Composite Available Capacity=Beam Capacity Class Value*Beam Capacity Value. The Beam Capacity Class Value (BCCV) indicates the total resources configured within the cell for traffic purposes in the coverage area of a reference signal beam. The Beam Capacity Value (BCV) indicates the amount of resources that are available within the coverage area of the downlink reference signal beam relative to the total resources BCCV. The following short hand notation 
         CAC   b =BCCV b   ·BCV   b    b= 1, . . . ,  N   beams    
     denotes the available capacity associated to the coverage area of N beams  downlink reference signals beams indexed by b=1, . . . , N beams . 
     The value of BCCV b  can be determined as a function of the cell capacity class value (CCCV) depending on how the cell resources are distributed among different downlink reference signal beams. In one example, BCCV b =CCCV for all reference signal beams in case of full reuse of the cell&#39;s resources among the coverage are of each reference signal beam. In another example, BCCV, can be fraction of CCCV such that Σ b=1   N     beams   BCCV b , =CCCV when the cell&#39;s resources are orthogonally divided among the coverage area of different reference signal beams. 
     In another example, when the cell&#39;s resources are partly reused among the coverage area of different SSB beams, BCCV b  can be a fraction of CCCV such that Σ b=1   N     beams    BCCV b ≥CCCV. For example, the cell may allow full reuse among the coverage areas of each SSB, but in practice at the border between the coverage area of two SSBs it is possible that the scheduler will use different resources, thus BCCV b ≤CCCV but Σ b=1   N     beams    BCCV b ≥CCCV. 
     In some embodiments, the available capacity associated to the radio cell is based on the available capacity associated to the coverage area of one or more reference signal beams. In one embodiment, the available capacity associated to the radio cell is computed as

     The sum of the available capacity CAC b  associated to the coverage area of multiple reference signal beams is scaled in proportion to the cell capacity class value normalized by the sum of the beam capacity class values. The normalization is useful in the case where the cell resources are reused, fully or only in part, between the coverage area of different reference signals.

     The cell available capacity is represented by the average available capacity associated to the coverage area of multiple reference signal beams. 
       FIG. 3  is a graph illustrating the available capacity associated to the coverage area of four SSB reference signals of a 3GPP NR system with the cell-specific available capacity as defined by the 3GPP LTE system and with the cell-specific available capacity, according to particular embodiments.  FIG. 3  illustrates how particular embodiments can be used to characterize the available capacity in different areas of a radio cell (e.g., the available capacity associated to the coverage area of different SSB beams) as well as to derive the cell-specific available cell capacity derived as a function of the available capacity in different areas of a radio cell.  FIG. 3  also illustrates a comparison with the cell-specific available capacity that could be derived if it were an LTE cell. Based on the illustrated example, the state of the art cannot capture how radio resources are used/available over the spatial domain, nor can it correctly infer the cell available capacity when radio resources can be spatially reused with MIMO beamforming techniques. 
     Particular embodiments include capacity associated to network slices. A partition of the radio cell is represented as a network slice. The available capacity associated to a network slice can be determined as: Slice Composite Available Capacity=Slice Capacity Class Value*Slice Capacity Value. The Slice Capacity Class Value (SCCV) indicates the total resources configured within the cell for traffic purposes in the coverage area of a reference signal beam. The Slice Capacity Value (SCV) indicates the amount of resources that are available for the network slice relative to the total resources SCCV. The short hand notation 
         CAC   s =SCCV s   ·SCVs   s =1, . . . ,  N   slices    
     denotes the available capacity associated to N slices  network slices indexed by s=1, . . . , N slices . 
     The value of SCCV s  can be determined as a function of the cell capacity class value (CCCV) depending on how the cell resources are distributed among different network slices. In one example, SCCV s =CCCV for all network slices if the cell resources can be fully reused by all network slices. In another example, SCCV s  can be fraction of CCCV such that Σ s=1   N     slices    SCCV s =CCCV in case the cell&#39;s resources are orthogonally divided among network slices. 
     In another example, when the cell&#39;s resources are partly reused among different network slices, SCCV s  can be fraction of CCCV such that Σ s=1   N     slices   SCCV s ≥CCCV. For instance, network slices may be configured to have a minimum guaranteed number of resources such that Σ s=1   N     slices   SCCV s,min =CCCV but could be allowed to pull resources from other network slices if their traffic is low, up to a maximum amount of resources. In this case, the value SCCV s  may be expressed associated to a network slice s to range in an interval [SCCV s,min ,SCCV s,max ]. 
     In some embodiments, the available capacity associated to the radio cell is determined based on the available capacity associated to one or more network slices. In one embodiment, the available capacity associated to the radio cell is computed as

     The sum of the available capacity CAC s  associated to the multiple network slices is scaled in proportion to the cell capacity class value normalized by the sum of the slice capacity class values. The normalization is useful in the case where the cell resources are reused, fully or only in part, between network slices. 
     In some embodiments, the available capacity associated to the radio cell is computed as

     The cell available capacity is represented by the average available capacity associated to all network slices. 
     Particular embodiments include available capacity associated to network slices and downlink reference signal beams. A partition of the radio cell is represented by the resource utilization associated to a network slice within the coverage area of a reference signal beam. The available capacity associated to a network slice s within the coverage area of a reference signal beam b can be determined as 
         CAC   s,b =SCCV s,b   ·SCV   s,b    S= 1, . . .  N   slices    b= 1, . . . ,  N   beams    
     where SCCV s,b  indicates the total resources configured for a slices within the coverage area of a beam b for traffic purposes, whereas SCV s,b  indicates the amount of resources that are available for the network slice within the coverage area of a reference signal beam relative to the total resources SCCV s,b . 
     The value of SCCV s  can be determined as a function of the cell capacity class value (CCCV) depending on how the cell resources are distributed among different network slices and the coverage area of downlink reference signal beams. In one example, SCCV s,b =CCCV for all network slices under the coverage area of all reference signal beams, i.e. the cell resources are fully reusable among all network slices and among the coverage area of all reference signal beams. 
     In another example, each network slice is associated a Slice Capacity Class Value SCCV s  representing a fraction of the cell CCCV such that Σ s=1   N     slices    SCCV s =CCCV (i.e., the cell&#39;s resources are orthogonally divided among network slices) and SCCV s,b =SCCV s  for all coverage areas of reference signal beams. In other words, the resources dedicated to a network slice are fully reusable among the coverage area of different reference signal beams. 
     In another example, each network slice is associated a Slice Capacity Class Value SCCV s  representing a fraction of the cell CCCV and SCCV s,b =SCCV s  for all coverage areas of reference signal beams. In other words, each network slice is allocated a fraction of the cell&#39;s network resources that may partly overlap with the resources allocated to another network slice, and the resources dedicated to a network slice are fully reusable among the coverage area of different reference signal beams. 
     In some embodiments, the available capacity associated to the radio cell is determined based on the available capacity associated to one or more network slices within the coverage area of one or more reference signal beams. In one embodiment, the available capacity associated to the radio cell is computed as

     In some embodiments, a partition of the radio cell is represented by a bandwidth part of an uplink or a downlink carrier band. Therefore, the radio network node computes the available capacity associated to one or more bandwidth part of a downlink or uplink carrier. 
     The network node can further compute the available capacity associate to the radio cell based on the available capacity associated with at least one bandwidth part. 
       FIG. 4  illustrates an example wireless network, according to certain embodiments. The wireless network may comprise and/or interface with any type of communication, telecommunication, data, cellular, and/or radio network or other similar type of system. In some embodiments, the wireless network may be configured to operate according to specific standards or other types of predefined rules or procedures. Thus, particular embodiments of the wireless network may implement communication standards, such as Global System for Mobile Communications (GSM), Universal Mobile Telecommunications System (UMTS), Long Term Evolution (LTE), New Radio (NR), and/or other suitable 2G, 3G, 4G, or 5G standards; wireless local area network (WLAN) standards, such as the IEEE 802.11 standards; and/or any other appropriate wireless communication standard, such as the Worldwide Interoperability for Microwave Access (WiMax), Bluetooth, Z-Wave and/or ZigBee standards. 
     Network  106  may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks (PSTNs), packet data networks, optical networks, wide-area networks (WANs), local area networks (LANs), wireless local area networks (WLANs), wired networks, wireless networks, metropolitan area networks, and other networks to enable communication between devices. 
     Network node  160  and WD  110  comprise various components described in more detail below. These components work together to provide network node and/or wireless device functionality, such as providing wireless connections in a wireless network. In different embodiments, the wireless network may comprise any number of wired or wireless networks, network nodes, base stations, controllers, wireless devices, relay stations, and/or any other components or systems that may facilitate or participate in the communication of data and/or signals whether via wired or wireless connections. 
     As used herein, network node refers to equipment capable, configured, arranged and/or operable to communicate directly or indirectly with a wireless device and/or with other network nodes or equipment in the wireless network to enable and/or provide wireless access to the wireless device and/or to perform other functions (e.g., administration) in the wireless network. 
     Examples of network nodes include, but are not limited to, access points (APs) radio access points), base stations (BSs) (e.g., radio base stations, Node Bs, evolved Node Bs (eNBs) and NR NodeBs (gNBs)). Base stations may be categorized based on the amount of coverage they provide (or, stated differently, their transmit power level) and may then also be referred to as femto base stations, pico base stations, micro base stations, or macro base stations. 
     A base station may be a relay node or a relay donor node controlling a relay. A network node may also include one or more (or all) parts of a distributed radio base station such as centralized digital units and/or remote radio units (RRUs), sometimes referred to as Remote Radio Heads (RRHs). Such remote radio units may or may not be integrated with an antenna as an antenna integrated radio. Parts of a distributed radio base station may also be referred to as nodes in a distributed antenna system (DAS). Yet further examples of network nodes include multi-standard radio (MSR) equipment such as MSR BSs, network controllers such as radio network controllers (RNCs) or base station controllers (BSCs), base transceiver stations (BTSs), transmission points, transmission nodes, multi-cell/multicast coordination entities (MCEs), core network nodes (e.g., MSCs, MMEs), O&amp;M nodes, OSS nodes. SON nodes, positioning nodes (e.g., E-SMLCs), and/or MDTs. 
     As another example, a network node may be a virtual network node as described in more detail below. More generally, however, network nodes may represent any suitable device (or group of devices) capable, configured, arranged, and/or operable to enable and/or provide a wireless device with access to the wireless network or to provide some service to a wireless device that has accessed the wireless network. 
     In  FIG. 4 , network node  160  includes processing circuitry  170 , device readable medium  180 , interface  190 , auxiliary equipment  184 , power source  186 , power circuitry  187 , and antenna  162 . Although network node  160  illustrated in the example wireless network of  FIG. 4  may represent a device that includes the illustrated combination of hardware components, other embodiments may comprise network nodes with different combinations of components. 
     It is to be understood that a network node comprises any suitable combination of hardware and/or software needed to perform the tasks, features, functions and methods disclosed herein. Moreover, while the components of network node  160  are depicted as single boxes located within a larger box, or nested within multiple boxes, in practice, a network node may comprise multiple different physical components that make up a single illustrated component (e.g., device readable medium  180  may comprise multiple separate hard drives as well as multiple RAM modules). 
     Similarly, network node  160  may be composed of multiple physically separate components (e.g., a NodeB component and a RNC component, or a BTS component and a BSC component, etc.), which may each have their own respective components. In certain scenarios in which network node  160  comprises multiple separate components (e.g., BTS and BSC components), one or more of the separate components may be shared among several network nodes. For example, a single RNC may control multiple NodeB&#39;s. In such a scenario, each unique NodeB and RNC pair, may in some instances be considered a single separate network node. 
     In some embodiments, network node  160  may be configured to support multiple radio access technologies (RATs). In such embodiments, some components may be duplicated (e.g., separate device readable medium  180  for the different RATs) and some components may be reused (e.g., the same antenna  162  may be shared by the RATs). Network node  160  may also include multiple sets of the various illustrated components for different wireless technologies integrated into network node  160 , such as, for example, GSM, WCDMA, LTE, NR, WiFi, or Bluetooth wireless technologies. These wireless technologies may be integrated into the same or different chip or set of chips and other components within network node  160 .

       FIG. 5  is a flowchart illustrating an example method in a network node, according to certain embodiments. In particular embodiments, one or more steps of  FIG. 5  may be performed by network node  160  described with respect to  FIG. 4 . The network node is operable to determine available capacity. 
     The method begins at step  512 , where the network node (e.g., network node  160 ) determines an available capacity of one or more partitions of a radio cell. For example, the partitions may comprise coverage areas of one or more reference signal beams, such as one or more synchronization signal blocks (SSBs) beams. In some embodiments, the one or more partitions of the radio cell may comprise one or more network slices, or the one or more partitions of the radio cell may comprise one or more network slices and coverage areas of one or more reference signal beams. 
     In particular embodiments, determining the available capacity of one or more partitions of the radio cell is based on all cell resources being available to each of the one or more partitions of the radio cell. 
     For example, the available capacity of a partition of the radio cell may be a composite available capacity comprising a partition capacity class value and a partition capacity value wherein the partition capacity class value is equal to a cell capacity class value, and the partition capacity value is an amount of resources available within the partition relative to the partition capacity class value. 
     In particular embodiments, determining the available capacity of one or more partitions of the radio cell is based on a fraction of cell resources being available to each of the one or more partitions of the radio cell. 
     For example, the available capacity of a partition of the radio cell may be a composite available capacity comprising a partition capacity class value and a partition capacity value wherein the partition capacity class value is smaller than a cell capacity class value and the sum of the partition capacity class value of all partitions equals the cell capacity class value, and the partition capacity value is the amount of resources available within the partition relative to the partition capacity class value. 
     As another example, the available capacity of a partition of the radio cell may be a composite available capacity comprising a partition capacity class value and a partition capacity value wherein the partition capacity class value is smaller than a cell capacity class value and the sum of the partition capacity class value of all partitions exceeds the cell capacity class value, and the partition capacity value is the amount of resources available within the partition relative to the partition capacity class value. 
     In some embodiments, the available capacity of a partition of the radio cell is determined according to any of the embodiments and examples described herein. 
     At step  514 , the network node may determine an available cell capacity for the radio cell based on the determined available capacity of the one or more partitions of the radio cell. For example, the network node may average each of the available capacities of the one or more partitions of the radio cell. In some embodiments, the network node determines the available cell capacity according to any of the embodiments and examples described herein. 
     At step  516 , the network node transmits a resource status information message to another network node. The resource status information message comprises at least one of the determined available capacities of the one or more partitions of the radio cell, and may also include the determined available cell capacity.
