- FIG. 2 shows a wireless network 200 with a New Generation Radio Access Network (NG-RAN) node, e.g., base station 208 gNB represented by node B equipped with M antennas, and K user equipments 202, 204, 206 (UEs) denoted by U 1 , U 2 , ---, U K each having N antennas.
- NG-RAN New Generation Radio Access Network
- H k (t) denotes a channel at time t over frequency band I, I G , between B and U k , which is a matrix of size N x M with complex entries, i.e., H k (t) G J’NXM
- the gNB may selects w k (t) that maximizes the received signal to noise ratio (SNR).
- SNR received signal to noise ratio
- the gNB may get knowledge of H k (t) by direct measurement (e.g., in Time Division Duplex, TDD, mode and assuming reciprocity of the channel), or indirectly using the information that the UE sends to the gNB (e.g., in Frequency Division Duplex, FDD, mode). In the latter case, large amounts of feedback may be required to send accurate information about H k (t). This becomes particularly important if there are large number of antennas or/and large frequency bands.
- H k denotes a matrix of size N X M X L which may be constructed by stacking H k for all frequency bands, i.e., the entries at H k [n, m, I is equal to H k [n, m], In total, therefore, each UE may need to send information about N x M x L complex numbers to the gNB.
- a two-sided model is one of the schemes presented to reduce the required feedback information where an encoding part (at the UE) computes a quantized latent representation 310 of input data 312; and the decoding part (at the gNB) may get this latent representation 310 and use it to reconstruct the desired output 314.
- the input data 312 in this case may be a dataset which is based on channel measurements. For example, it could be the raw channel inputs of H k or H k , or, for example, precoders that are computed from the channel matrix, e.g., the eigenvector associated with the largest eigen-vector of H k for each sub-band.
- Figure 3 depicts a high-level structure of a two-sided model 300 with NN-based node A 302 (e.g., UE) and node B 304 (e.g., gNB) referred to here as M e (encoding model) 306 and M d (decoding model) 308, respectively. Note that this is an example: the locations of the encoder 306 and decoder 308 represented in Figure 3 may be interchanged.
- Models M e 306 and M d 308 may be logical models. This means that node A 302 may choose not to use M e 306 directly and instead develop and use several internal models like M e ⁇ , based on some private parameters and decisions. In these examples, these internal models may meet at least the performance of pairing original M e 306 with M d 308. In this example, node B 304 may not need to know what the actual model used at the node A 302 is. The corollary may be true for M d 308 and internal models at node B 304.
- NN Neural Network
- Updating a two-sided model may be carried out centrally on one entity, on different entities but simultaneously, or separately.
- the NN modules of the node A 302 e.g., UE 202
- the node B 304 e.g., gNB 208
- the NN modules of the node A 302 and the node B 304 are trained in different training sessions (no forward or backpropagation path between the two parts).
- node A 302 and node B 304 do not need to be aware of the internal structure of the NN module of the other side.
- Figure 4 illustrates a one-sided model 400 with NN-based node A 402 (e.g., a UE) and node B 404 (e.g., a gNB).
- node A 402 has a model M A 406 for encoding, there being no model (indicated by 408) for decoding at node B 404.
- the node A 402 applies model 406 to input data 412 to get result 410 for passing to node B 404.
- Figure 5 illustrates a one-sided model 500 with NN-based node A 502 (e.g., a UE) and node B 504 (e.g., a gNB).
- node B 504 has a model M B 508 for decoding, there being no model (indicated by 506) for encoding at node A 502.
- the node B 504 applies model 508 to transmitted data 510 from node A 502 to get output 514.
- node A and node B may decide not to use a single Encoder-Decoder pair, and instead may construct different encode-decoder pairs which apply to different conditions of node A and/or node B since the samples of different states may have different statistics compared to other settings, and, therefore, it may be advantageous to construct two different encoder-decoder model for these two cases instead of trying to train a single model that can generalize well to different settings.
- condition refers to when the parameters of node A and node B are in a certain state.
- the node A/node B may decide on which of these models should be activated based on the current node A/node B states.
- Node A may be connected to different node Bs, and vice versa, i.e., one node B may be connected to different node As.
- node A could be a UE equipped with a Qualcomm chipset, and the node B could a gNB manufactured by Ericsson or Nokia.
- node A may develop a model in collaboration with each of the node Bs.
- Qualcomm and Ericsson collaborate to generate M 1 (QI represents the first encoder model of Qualcomm chipset) (El represents the first decoder model of the Ericsson gNB).
- Qualcomm and Ericsson may collaborate to generate Mg 2 (Q2 represents the second encoder model of Qualcomm chipset) and M ⁇ 1 (N1 represents the first decoder model of the Nokia gNB).
- node A/node B may select an appropriate model during an inference phase.
- node A and node B may not want to reveal their identity to the other.
- the Qualcomm chipset may select between Mg 1 and Mg 2 , but the gNB side may not want to tell the Qualcomm chipset if is a gNB made by Ericsson or Nokia.
- data may be gathered from different node As and node Bs and a single model may be generated that works with all pairs. For example, data may be collected from both Ericsson and Nokia gNBs and a model may be trained that works for both. Then, during the inference phase, the UE may not decide which model to use (as it only has one model) and therefore it may not need to know the identity of the other side.
- a drawback of this example may be that, based on the use-case and the model structure, the performance of one single model which is applicable to all different node A-node B pairs may be inferior to having separate models each of them for a group of node A-node B pairs, so performance may be improved by training different models and then finding a way for correct model selection during the inference phase.
- Another difficulty of this example may be that collaboration between different node As and node Bs (during the training phase) to train a single model, while possible, may be impractical. In the above example, it may not be practical to ask different chipset vendors and gNB vendors to collaborate together to determine a model that works for all pairing situations.
- an ID may be assigned to that model and then, during the inference phase, each node may tell the other node which of the models should be selected.
- node A has two encoder models with proxy identifiers ID-A and ID-B.
- Ericsson has one decoder model with proxy identifier ID-A
- Nokia has one decode model with proxy identifier ID-B.
- the UE chipset vendor e.g., Qualcomm chipset
- a gNB vendor e.g., Nokia gNB but it does not know the identity of the gNB. So, the UE may query gNB as to what model the UE may use. Then, the gNB may respond (or the gNB may send this information proactively, before even the question from the node A side) that the gNB supports a decoder with Model represented by identifier ID-A (without revealing that the gNB is associated with Ericsson or Nokia). Receiving this message, the Qualcomm chipset may activate the associated encoder model for Model ID-A without actual knowledge of the gNB vendor.
- identifier ID-A without actual knowledge of the gNB vendor.
- a two-sided model with M e (encoder) and M d (decoder) parts residing at a node A and node B, respectively, is trained, in which there may be L different types of node A and K different types of node Bs.
- Node As may be different chipsets used in different UEs, e.g., Low-end Qualcomm chipset, high-end Qualcomm chipset, high-end MediaTek chipset, etc.
- Node As may be different OEMs/UEs, e.g., Motorola glOO first gen, Motorola glOO second get, Motorola Razr40, Apple iPhone 13, etc.
- Node Bs may be different gNB manufacturers/vendors, e.g., Ericsson first generation gNB, Nokia first generation gNB, Nokia second generation gNB, etc.
- a few types may be grouped together for consideration as one type. For example, if for a use case there is no difference between a Low-end Qualcomm chipset and a high-end Qualcomm chipset the two may be considered as one type of UE chipset, instead of two types.
- node As there may be a few types of node As and a few types of node Bs who participate in the training of a two-sided model.
- node Bs who participate in the training of a two-sided model.
- a separate two-sided model for each pair may be trained.
- node As, and node Bs may not be willing to reveal their Types to the other side.
- Node A may send an identifier (ID) to the other side with which the other side can determine the particular node B (node A) is connected to.
- This ID may not reveal information about the type of the other side.
- This ID may be referred to as a pairing identifier or pairing ID.
- a current Cell-ID of a UE may show the gNB it is connected to, and it does not reveal who the manufacturer of that gNB is.
- an International Mobile Equipment Identity (IMEI) can be used to determine which UE a gNB is connected to, and it does not tell which chipset is used in that UE. In examples, either or both of these may therefore be useable as a pairing ID.
- IMEI International Mobile Equipment Identity
- a model like M , is trained if the nodes node A and node B participating in training are aware of each other's model types. Whenever one side selects that particular model M , the other side may indirectly understand the type of the first side.
- a gateway node G A may be designated. If there are multiple groups, then there are multiple gateway nodes G A1 to G Am .
- gateway node properties may include: a. The node As who are associated with that gateway node may share their types with that Gateway. b. Gateways of node As may be identified from node Bs and may be accessible at least from a node at the node-B side.
- an over-the-top (OTT) server from Lenovo may be the designated gateway for all UEs manufactured by Lenovo.
- Lenovo ma already knows their types, i.e., what chipset has been used in eachUE, e.g., Qualcomm high-end chipset, or MediaTek chipset. Therefore, no extra information is revealed.
- a network is already able to determine the manufacturer of a UE which is connected to it. Therefore, even though the network, e.g., gNB, is not able to determine the chipset used in a UE, it can determine that the gateway of the UE should be Lenovo.
- the network e.g., gNB
- the gNB may not have direct access to Lenovo Gateway, it may rely on another node in NW side to communicate with Lenovo gateway.
- a gateway node G B is designated. If there are multiple groups, then there are multiple gateway nodes G B1 to G Bm .
- gateway node properties may include: a. The node Bs who are associated with that gateway may share their types with that Gateway. b. Gateways of node Bs may be identified from node As.
- an operations and management (0AM) server from an operator of the network could be the designated gateway for all gNBs owned by T- Mobile.
- T-Mobile may already know their types, i.e., their manufacturer, e.g., Ericsson first generation gNB, Nokia first generation gNB, Nokia second generation gNB. Therefore, no extra information is revealed.
- each UE is able to determine the operator that it is connected to. Therefore, even though the UE is not able to determine the gNB manufacturer, it can determine that the gateway of that gNB should be T-Mobile. Note that since the UE may not have direct access to T-Mobile Gateway, it may rely on another node in NW side to communicate with the Lenovo gateway.
- a node Type from one side sends their request to their gateway node notifying the gateway node that they want to train a model.
- the gateway may associate a proxy-ID with that type.
- the term G ⁇ D may be used to refer to this proxy-ID. If that type was previously assigned with an ID, it may use that ID, otherwise the gateway node may generate a new random number which has not been previously used at this gateway node for that type.
- a model for Lenovo UEs of type 1, e.g., with high-end Qualcomm chipset may be trained.
- G A and node As may collaboratively determine a proxy-ID to each of the node As and may pre-assign the proxy-ID to that node A. Following this scheme, node A does not need to receive its proxy-ID from the G A during the data-collection phase, node A may only transmit a request to G A notifying the gateway that they want to train the model.
- G A then may determine a pairing -ID and/or ask all node As of a particular Type to send it their pairing-IDs that the gateway may use to determine which node B they are connecting to.
- Lenovo G A may ask all UEs with high-end Qualcomm chipset to send the Cell-ID that they are associated with.
- Lenovo G A may use IMEI of the UEs with high-end Qualcomm chipset. Since the network side knows which IMEI is connected to which cell it can determine the connected gNB.
- G A may notify the G B that the UEs with a certain G A D want to collect data for training of their model and may send G B their pairing-IDs.
- G B may determine the node Bs who are connected to node As and may determine their Types. G B , then, may associate a proxy-ID with each of the types. Term G B D may be used to refer to this proxy-ID. If that type was previously assigned with an ID, it may use that ID, otherwise the gateway may generate a new random number which has not been previously used at this gateway for that type.
- G B and node Bs may collaboratively determine a proxy-ID to each of the node Bs and may pre-assign the proxy-ID to that node B. Following this scheme, node B does not need to receive its proxy-ID from the G B during the data-collection phase.
- G B may notify the G A with the information on the G B D of the node B that each node A with certain Pairing-ID is connected to.
- both sides may know that there are two groups of (node A, node B) pairs, for example
- data collection and model training may be carried out for each group.
- node As with similar (G A D , G B D ⁇ ) may participate in data collection and may use the training dataset. The collected data may then be used for training the encoder model for (G A D , G B D ) ⁇ . The dataset required for construction of the paired decoder model may be constructed.
- the constructed dataset may be sent to node B-side with an indication that this dataset is for (G A D , G B D ) ⁇ .
- the dataset may be sent to G B (directly or via G A ) and G B may direct it to appropriate server/node owned by the node B with that particular iD
- G B may send an IP address of the server/node owned by the node B with that particular G B D , so the data of (G A D , G B D ) may be sent directly to that server/node.
- the node B-side server/node may train the decoder model of the two-sided model associated with (G A D , G B D [0104]
- node As with similar G A D may send their data to the node B-side indicating that this dataset is for G A D .

- G B may send an IP address of the node owned by the node B with that particular G B D , so the data of (G A D , B D ) may be sent directly to that server/node.
- Each node B type may then have the training dataset for different (G A D , B D ) if there are multiple G A D s.
- the server/node owned by the node B with that particular G B D may train the decoder model for (G A D , G B D ⁇ ) and may also construct the dataset required for construction of the paired encoder model.

DETAILED DESCRIPTION
[0020] During communication between nodes in a network, it may be desirable to maintain information regarding a type of a node as secret from other nodes. At the same time, it may be desirable to use a most appropriate means for encoding and/or decoding messages transmitted between the nodes.
[0021] Examples of the present disclosure tend to facilitate selection of a most appropriate, efficient, and/or secure encoding and/or decoding model for increasing both security and efficiency of communication.
[0022] Aspects of the present disclosure are described in the context of a wireless communications system.
[0023] Figure 1 illustrates an example of a wireless communications system 100 in accordance with aspects of the present disclosure. The wireless communications system 100 may include one or more NE 102, one or more UE 104, and a core network (CN) 106. The wireless communications system 100 may support various radio access technologies. In some implementations, the wireless communications system 100 may be a 4G network, such as an LTE network or an LTE- Advanced (LTE-A) network. In some other implementations, the wireless communications system 100 may be a NR network, such as a 5G network, a 5G- Advanced (5G-A) network, or a 5G ultrawideband (5G-UWB) network. In other implementations, the wireless communications system 100 may be a combination of a 4G network and a 5G network, or other suitable radio access technology including Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20. The wireless communications system 100 may support radio access technologies beyond 5G, for example, 6G. Additionally, the wireless communications system 100 may support technologies, such as time division multiple access (TDMA), frequency division multiple access (FDMA), or code division multiple access (CDMA), etc.
[0024] The one or more NE 102 may be dispersed throughout a geographic region to form the wireless communications system 100. One or more of the NE 102 described herein may be or include or may be referred to as a network node, a base station, a network element, a network function, a network entity, a radio access network (RAN), a nodeB, an enodeB (eNB), a next-generation nodeB (gNB), or other suitable terminology. An NE 102 and a UE 104 may communicate via a communication link, which may be a wireless or wired connection. For example, an NE 102 and a UE 104 may perform wireless communication (e.g., receive signalling, transmit signalling) over a Uu interface.
[0025] An NE 102 may provide a geographic coverage area for which the NE 102 may support services for one or more UEs 104 within the geographic coverage area. For example, an NE 102 and a UE 104 may support wireless communication of signals related to services (e.g., voice, video, packet data, messaging, broadcast, etc.) according to one or multiple radio access technologies. In some implementations, an NE 102 may be moveable, for example, a
satellite associated with a non-terrestrial network (NTN). In some implementations, different geographic coverage areas associated with the same or different radio access technologies may overlap, but the different geographic coverage areas may be associated with different NE 102.
[0026] The one or more UE 104 may be dispersed throughout a geographic region of the wireless communications system 100. A UE 104 may include or may be referred to as a remote unit, a mobile device, a wireless device, a remote device, a subscriber device, a transmitter device, a receiver device, or some other suitable terminology. In some implementations, the UE 104 may be referred to as a unit, a station, a terminal, or a client, among other examples. Additionally, or alternatively, the UE 104 may be referred to as an Internet-of-Things (loT) device, an Internet-of-Everything (loE) device, or machine-type communication (MTC) device, among other examples.
[0027] A UE 104 may be able to support wireless communication directly with other UEs 104 over a communication link. For example, a UE 104 may support wireless communication directly with another UE 104 over a device- to-device (D2D) communication link. In some implementations, such as vehicle-to-vehicle (V2V) deployments, vehicle-to-everything (V2X) deployments, or cellular-V2X deployments, the communication link may be referred to as a sidelink. For example, a UE 104 may support wireless communication directly with another UE 104 over a PC5 interface.
[0028] An NE 102 may support communications with the CN 106, or with another NE 102, or both. For example, an NE 102 may interface with other NE 102 or the CN 106 through one or more backhaul links (e.g., SI, N2, N2, or network interface). In some implementations, the NE 102 may communicate with each other directly. In some other implementations, the NE 102 may communicate with each other or indirectly (e.g., via the CN 106. In some implementations, one or more NE 102 may include subcomponents, such as an access network entity, which may be an example of an access node controller (ANC). An ANC may communicate with the one or more UEs 104 through one or more other access network transmission entities, which may be referred to as a radio heads, smart radio heads, or transmission-reception points (TRPs).
[0029] The CN 106 may support user authentication, access authorization, tracking, connectivity, and other access, routing, or mobility functions. The CN 106 may be an evolved packet core (EPC), or a 5G core (5GC), which may include a control plane entity that manages access and mobility (e.g., a mobility management entity (MME), an access and mobility management functions (AMF)) and a user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW), a Packet Data Network (PDN) gateway (P-GW), or a user plane function (UPF)). In some implementations, the control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management (e.g., data bearers, signal bearers, etc.) for the one or more UEs 104 served by the one or more NE 102 associated with the CN 106.
[0030] The CN 106 may communicate with a packet data network over one or more backhaul links (e.g., via an SI, N2, N2, or another network interface). The packet data network may include an application server. In some implementations, one or more UEs 104 may communicate with the application server. A UE 104 may establish a session (e.g., a protocol data unit (PDU) session, or the like) with the CN 106 via an NE 102. The CN 106 may route traffic (e.g., control information, data, and the like) between the UE 104 and the application server using the established session (e.g., the established PDU session). The PDU session may be an example of a logical connection between the UE 104 and the CN 106 (e.g., one or more network functions of the CN 106).
[0031] In the wireless communications system 100, the NEs 102 and the UEs 104 may use resources of the wireless communications system 100 (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers)) to perform various operations (e.g., wireless communications). In some implementations, the NEs 102 and the UEs 104 may support different resource structures. For example, the NEs 102 and the UEs 104 may support different frame structures. In some implementations, such as in 4G, the NEs 102 and the UEs 104 may support a single frame structure. In some other implementations, such as in 5 G and among other suitable radio access technologies, the NEs 102 and the UEs 104 may support various frame structures (i.e., multiple frame structures). The NEs 102 and the UEs 104 may support various frame structures based on one or more numerologies.
[0032] One or more numerologies may be supported in the wireless communications system 100, and a numerology may include a subcarrier spacing and a cyclic prefix. A first numerology (e.g., /r=0) may be associated with a first subcarrier spacing (e.g., 15 kHz) and a normal cyclic prefix. In some implementations, the first numerology (e.g., /r=0) associated with the first subcarrier spacing (e.g., 15 kHz) may utilize one slot per subframe. A second numerology (e.g., /r=l) may be associated with a second subcarrier spacing (e.g., 30 kHz) and a normal cyclic prefix. A third numerology (e.g., /r=2) may be associated with a third subcarrier spacing (e.g., 60 kHz) and a normal cyclic prefix or an extended cyclic prefix. A fourth numerology (e.g., /r=3) may be associated with a fourth subcarrier spacing (e.g., 120 kHz) and a normal cyclic prefix. A fifth numerology (e.g., /r=4) may be associated with a fifth subcarrier spacing (e.g., 240 kHz) and a normal cyclic prefix.
[0033] A time interval of a resource (e.g., a communication resource) may be organized according to frames (also referred to as radio frames). Each frame may have a duration, for example, a 10 millisecond (ms) duration. In some implementations, each frame may include multiple subframes. For example, each frame may include 10 subframes, and each subframe may have a duration, for example, a 1 ms duration. In some implementations, each frame may have the same duration. In some implementations, each subframe of a frame may have the same duration.
[0034] Additionally, or alternatively, a time interval of a resource (e.g., a communication resource) may be organized according to slots. For example, a subframe may include a number (e.g., quantity) of slots. The number of slots in each subframe may also depend on the one or more numerologies supported in the wireless communications system 100. For instance, the first, second, third, fourth, and fifth numerologies (i.e., /r=0, /r=l, /r=2, /r=3, /r=4) associated with respective subcarrier spacings of 15 kHz, 30 kHz, 60 kHz, 120 kHz, and 240 kHz may utilize a single slot per subframe, two slots per subframe, four slots per subframe, eight slots per subframe, and 16 slots per subframe, respectively. #Each slot may include a number (e.g., quantity) of symbols (e.g., OFDM symbols). In some implementations, the number (e.g., quantity) of slots for a subframe may depend on a numerology. For a normal cyclic prefix, a slot may include 14 symbols. For an extended cyclic prefix (e.g., applicable for 60 kHz subcarrier spacing), a slot may include 12 symbols.
The relationship between the number of symbols per slot, the number of slots per subframe, and the number of slots per frame for a normal cyclic prefix and an extended cyclic prefix may depend on a numerology. It should be understood that reference to a first numerology (e.g., /r =0) associated with a first subcarrier spacing (e.g., 15 kHz) may be used interchangeably between subframes and slots.
[0035] In the wireless communications system 100, an electromagnetic (EM) spectrum may be split, based on frequency or wavelength, into various classes, frequency bands, frequency channels, etc. By way of example, the wireless communications system 100 may support one or multiple operating frequency bands, such as frequency range designations FR1 (410 MHz - 7.125 GHz), FR2 (24.25 GHz - 52.6 GHz), FR3 (7.125 GHz - 24.25 GHz), FR4 (52.6 GHz - 114.25 GHz), FR4a or FR4-1 (52.6 GHz - 71 GHz), and FR5 (114.25 GHz - 300 GHz). In some implementations, the NEs 102 and the UEs 104 may perform wireless communications over one or more of the operating frequency bands. In some implementations, FR1 may be used by the NEs 102 and the UEs 104, among other equipment or devices for cellular communications traffic (e.g., control information, data). In some implementations, FR2 may be used by the NEs 102 and the UEs 104, among other equipment or devices for short-range, high data rate capabilities.
[0036] FR1 may be associated with one or multiple numerologies (e.g., at least three numerologies). For example, FR1 may be associated with a first numerology (e.g., /r=0), which includes 15 kHz subcarrier spacing; a second numerology (e.g., /r=l), which includes 30 kHz subcarrier spacing; and a third numerology (e.g., /r=2), which includes 60 kHz subcarrier spacing. FR2 may be associated with one or multiple numerologies (e.g., at least 2 numerologies). For example, FR2 may be associated with a third numerology (e.g., /r=2), which includes 60 kHz subcarrier spacing; and a fourth numerology (e.g., /r=3), which includes 120 kHz subcarrier spacing.
[0037] Figure 2 shows a wireless network 200 with a New Generation Radio Access Network (NG-RAN) node, e.g., base station 208 gNB represented by node B equipped with M antennas, and K user equipments 202, 204, 206 (UEs) denoted by U1, U2, ---, UK each having N antennas.
[0038] Hk(t) denotes a channel at time t over frequency band I, I G
, between B and Uk, which is a matrix of size N x M with complex entries, i.e., Hk(t) G J’NXM
[0039] At time t and in frequency band I, the gNB may want to transmit message x (t) to user Uk, where k = {1,2, ••• , K}, while it uses wk(t) G CMxl as the precoding vector. The received signal at Uk, y Ct), can be written as: yk(t) = Hk(t)wk(t)xk(t) + nk(t) where nk(t) represents the noise vector at the receiver.
[0040] To improve the achievable rate of the link, the gNB may selects wk(t) that maximizes the received signal to noise ratio (SNR). Several schemes have been proposed for good selection of wk(t) where most of them rely on having some knowledge about Hk(t).
[0041] The gNB may get knowledge of Hk(t) by direct measurement (e.g., in Time Division Duplex, TDD, mode and assuming reciprocity of the channel), or indirectly using the information that the UE sends to the gNB (e.g., in Frequency Division Duplex, FDD, mode). In the latter case, large amounts of feedback may be required to send accurate information about Hk(t). This becomes particularly important if there are large number of antennas or/and large frequency bands.
[0042] Hk denotes a matrix of size N X M X L which may be constructed by stacking Hk for all frequency bands, i.e., the entries at Hk[n, m, I is equal to Hk[n, m], In total, therefore, each UE may need to send information about N x M x L complex numbers to the gNB.
[0043] With reference to Figure 3, a two-sided model is one of the schemes presented to reduce the required feedback information where an encoding part (at the UE) computes a quantized latent representation 310 of input data 312; and the decoding part (at the gNB) may get this latent representation 310 and use it to reconstruct the desired output 314. The input data 312 in this case may be a dataset which is based on channel measurements. For example, it could be the raw channel inputs of Hk or Hk, or, for example, precoders that are computed
from the channel matrix, e.g., the eigenvector associated with the largest eigen-vector of Hk for each sub-band.
[0044] Figure 3 depicts a high-level structure of a two-sided model 300 with NN-based node A 302 (e.g., UE) and node B 304 (e.g., gNB) referred to here as Me(encoding model) 306 and Md(decoding model) 308, respectively. Note that this is an example: the locations of the encoder 306 and decoder 308 represented in Figure 3 may be interchanged.
[0045] Models Me 306 and Md 308 may be logical models. This means that node A 302 may choose not to use Me 306 directly and instead develop and use several internal models like Me^ ,
based on some private parameters and decisions. In these examples, these internal models may meet at least the performance of pairing original Me 306 with Md 308. In this example, node B 304 may not need to know what the actual model used at the node A 302 is. The corollary may be true for Md 308 and internal models at node B 304.
[0046] There are several ways to train the Neural Network (NN) modules of a two-sided model, including, but not limited to: centralized training; simultaneous training; and separate training. Updating a two-sided model may be carried out centrally on one entity, on different entities but simultaneously, or separately. In separate training/model update, the NN modules of the node A 302 (e.g., UE 202) and the node B 304 (e.g., gNB 208) are trained in different training sessions (no forward or backpropagation path between the two parts). In separate training, node A 302 and node B 304 do not need to be aware of the internal structure of the NN module of the other side.
[0047] There are also some other use cases, e.g., CSI prediction or Beam Management or Positioning, wherein the model is only at one side, i.e., node A-Side, or node B-Side. Figure 4 and Figure 5 are example high-level demonstrations of these two cases.
[0048] Figure 4 illustrates a one-sided model 400 with NN-based node A 402 (e.g., a UE) and node B 404 (e.g., a gNB). node A 402 has a model MA 406 for encoding, there being no model (indicated by 408) for decoding at node B 404. The node A 402 applies model 406 to input data 412 to get result 410 for passing to node B 404.
[0049] Figure 5 illustrates a one-sided model 500 with NN-based node A 502 (e.g., a UE) and node B 504 (e.g., a gNB). node B 504 has a model MB 508 for decoding, there being no model (indicated by 506) for encoding at node A 502. The node B 504 applies model 508 to transmitted data 510 from node A 502 to get output 514.
[0050] To train a model for a specific use case, node A and node B may decide not to use a single Encoder-Decoder pair, and instead may construct different encode-decoder pairs which apply to different conditions of node A and/or node B since the samples of different states may have different statistics compared to other settings, and, therefore, it may be advantageous to construct two different encoder-decoder model for these two cases instead of trying to train a single model that can generalize well to different settings. For example, for CSI feedback use case, it may be advantageous to have separate encoder- decoder pairs for UMA environment and indoor environment, compared to the case of building a single encoder- decoder pair covering both environments. There it may be beneficial to design Me[i] — Md[i] , for i = {1,2,
where the itfl pair is trained based on a training data collected when node A and node B are in one or a set of conditions. Here, condition refers to when the parameters of node A and node B are in a certain state.
[0051] Having multiple models for different states of the node A and node B, during inference phase, the node A/node B may decide on which of these models should be activated based on the current node A/node B states.
[0052] Node A may be connected to different node Bs, and vice versa, i.e., one node B may be connected to different node As. For example, in case of CSI feedback, node A, could be a UE equipped with a Qualcomm chipset, and the node B could a gNB manufactured by Ericsson or Nokia.
[0053] In these scenarios where there are two-sided models and a separate training scheme (where the encoder and decoder parts are trained respectively on two nodes owned by the node A and node B sides), node A may develop a model in collaboration with each of the node Bs. In an example, Qualcomm and Ericsson collaborate to generate M 1 (QI represents the first encoder model of Qualcomm chipset)
(El represents the first decoder model of the Ericsson gNB). In addition, Qualcomm and Ericsson may collaborate
to generate Mg 2 (Q2 represents the second encoder model of Qualcomm chipset) and M^1 (N1 represents the first decoder model of the Nokia gNB).
[0054] After training of the models, there may be multiple (encoder) models (at node A- side) associated with different node Bs and there may also be multiple (decoder) models (at node B-side) associated with different node As.
[0055] There may be a mechanism for node A/node B to select an appropriate model during an inference phase. During the inference phase, node A and node B may not want to reveal their identity to the other. In an example, during the inference time, the Qualcomm chipset may select between Mg 1 and Mg 2 , but the gNB side may not want to tell the Qualcomm chipset if is a gNB made by Ericsson or Nokia.
[0056] The following disclosure sets out examples of how node A and node B may determine an appropriate model that may be used during an inference phase in a transparent manner.
[0057] In an example, during the inference phase, node A (node B) may tell node B (node A) about its identity and then each side determines a correct model to use based on the identity of the other size. However, during the inference phase node A/node B does not want to tell/reveal its identity to the other side, so while this arrangement works, identity is revealed.
[0058] During training of a model, data may be gathered from different node As and node Bs and a single model may be generated that works with all pairs. For example, data may be collected from both Ericsson and Nokia gNBs and a model may be trained that works for both. Then, during the inference phase, the UE may not decide which model to use (as it only has one model) and therefore it may not need to know the identity of the other side. A drawback of this example may be that, based on the use-case and the model structure, the performance of one single model which is applicable to all different node A-node B pairs may be inferior to having separate models each of them for a group of node A-node B pairs, so performance may be improved by training different models and then finding a way for correct model selection during the inference phase. Another difficulty of this example may be that collaboration between different node As and node Bs (during the training phase) to
train a single model, while possible, may be impractical. In the above example, it may not be practical to ask different chipset vendors and gNB vendors to collaborate together to determine a model that works for all pairing situations.
[0059] In an example, after training a model between each pair, an ID may be assigned to that model and then, during the inference phase, each node may tell the other node which of the models should be selected. In an example, there may be assigned identifiers, such as proxy identifiers denoted ID-A and ID-B, to M 1 —
and M 1 — Md respectively. In this example, node A has two encoder models with proxy identifiers ID-A and ID-B. Ericsson has one decoder model with proxy identifier ID-A and Nokia has one decode model with proxy identifier ID-B.
[0060] In an example, during inference, the UE chipset vendor, e.g., Qualcomm chipset, may be attached to a gNB vendor, e.g., Nokia gNB but it does not know the identity of the gNB. So, the UE may query gNB as to what model the UE may use. Then, the gNB may respond (or the gNB may send this information proactively, before even the question from the node A side) that the gNB supports a decoder with Model represented by identifier ID-A (without revealing that the gNB is associated with Ericsson or Nokia). Receiving this message, the Qualcomm chipset may activate the associated encoder model for Model ID-A without actual knowledge of the gNB vendor.
[0061] This example avoids direct communication of node identities. However, when one node reveals its supported model ID, its identity may be also revealed, indirectly, to the other side.
[0062] In the above example, when the gNB side tells node A side that it supports Model ID-A, then the Qualcomm chipset may infer it the gNB is an Ericsson gNB as it has previously trained Model ID-A with Ericsson collaboration.
[0063] The following examples apply for both one-sided and two-sided models but, for conciseness, the two-sided model scenario is discussed.
[0064] In an example, a two-sided model with Me (encoder) and Md (decoder) parts residing at a node A and node B, respectively, is trained, in which there may be L different types of node A and K different types of node Bs.
[0065] Node As may be different chipsets used in different UEs, e.g., Low-end Qualcomm chipset, high-end Qualcomm chipset, high-end MediaTek chipset, etc.
[0066] Node As may be different OEMs/UEs, e.g., Motorola glOO first gen, Motorola glOO second get, Motorola Razr40, Apple iPhone 13, etc.
[0067] Node Bs may be different gNB manufacturers/vendors, e.g., Ericsson first generation gNB, Nokia first generation gNB, Nokia second generation gNB, etc.
[0068] While specific company names are used herein for illustrative purposes, it should be understood that the UE and gNB devices could come from any UE and gNB manufacturers and that implementation of the disclosure is not dependent on or more particular manufacturer.
[0069] Depending on the use case, statistics of the data, and/or agreement between owner of different types, a few types may be grouped together for consideration as one type. For example, if for a use case there is no difference between a Low-end Qualcomm chipset and a high-end Qualcomm chipset the two may be considered as one type of UE chipset, instead of two types.
[0070] In an example, all possible such groupings may be conducted and there may be L different types of node As and K different types of node Bs.
[0071] In an example, there may be a few types of node As and a few types of node Bs who participate in the training of a two-sided model. In an example, to improve performance of the model a separate two-sided model for each pair may be trained.
[0072] Depending on the use-case and other conditions, in an example, a single model that works with all pair of node As and node Bs may be trained, or all node As and node Bs may be combined into one type (L = 1, and K = 1), such that a single model (which is generalizable for all pairs) may be trained and there is no need for model selection.
[0073] During the inference phase, node As, and node Bs may not be willing to reveal their Types to the other side.
[0074] Node A (node B) may send an identifier (ID) to the other side with which the other side can determine the particular node B (node A) is connected to. This ID may not
reveal information about the type of the other side. This ID may be referred to as a pairing identifier or pairing ID.
[0075] In an example, a current Cell-ID of a UE may show the gNB it is connected to, and it does not reveal who the manufacturer of that gNB is. In another example, an International Mobile Equipment Identity (IMEI) can be used to determine which UE a gNB is connected to, and it does not tell which chipset is used in that UE. In examples, either or both of these may therefore be useable as a pairing ID.
[0076] A model, like M , is trained if the nodes node A and node B participating in training are aware of each other's model types. Whenever one side selects that particular model M , the other side may indirectly understand the type of the first side.
[0077] Following examples set out examples in which the sides collaborating in training may not know the actual type of the other side.
[0078] In an example, for all or each group of node A types, a gateway node GA may be designated. If there are multiple groups, then there are multiple gateway nodes GA1 to GAm.
[0079] In examples, gateway node properties may include: a. The node As who are associated with that gateway node may share their types with that Gateway. b. Gateways of node As may be identified from node Bs and may be accessible at least from a node at the node-B side.
[0080] In an example, an over-the-top (OTT) server from Lenovo may be the designated gateway for all UEs manufactured by Lenovo. In this example, as these UEs are manufactured by Lenovo, Lenovo ma already knows their types, i.e., what chipset has been used in eachUE, e.g., Qualcomm high-end chipset, or MediaTek chipset. Therefore, no extra information is revealed. From current defined 3 GPP signalling, a network is already able to determine the manufacturer of a UE which is connected to it. Therefore, even though the network, e.g., gNB, is not able to determine the chipset used in a UE, it can determine that the gateway of the UE should be Lenovo. Note that since the gNB may not have direct access
to Lenovo Gateway, it may rely on another node in NW side to communicate with Lenovo gateway.
[0081] In an example, for all or each group of the node B types, a gateway node GB is designated. If there are multiple groups, then there are multiple gateway nodes GB1 to GBm.
[0082] In examples, gateway node properties may include: a. The node Bs who are associated with that gateway may share their types with that Gateway. b. Gateways of node Bs may be identified from node As.
[0083] In an example, an operations and management (0AM) server from an operator of the network, e.g., T-Mobile could be the designated gateway for all gNBs owned by T- Mobile. As these gNBs are owned by T-Mobile, T-Mobile may already know their types, i.e., their manufacturer, e.g., Ericsson first generation gNB, Nokia first generation gNB, Nokia second generation gNB. Therefore, no extra information is revealed. From current defined 3GPP signalling, each UE is able to determine the operator that it is connected to. Therefore, even though the UE is not able to determine the gNB manufacturer, it can determine that the gateway of that gNB should be T-Mobile. Note that since the UE may not have direct access to T-Mobile Gateway, it may rely on another node in NW side to communicate with the Lenovo gateway.
[0084] In an example, a node Type from one side, for example, node A-side, sends their request to their gateway node notifying the gateway node that they want to train a model. The gateway may associate a proxy-ID with that type. The term G^D may be used to refer to this proxy-ID. If that type was previously assigned with an ID, it may use that ID, otherwise the gateway node may generate a new random number which has not been previously used at this gateway node for that type.
[0085] In an example, a model for Lenovo UEs of type 1, e.g., with high-end Qualcomm chipset may be trained. In this example, the Lenovo gateway assigns a number, e.g., G^D = 4, to that particular node A type.
[0086] In an example, GA and node As may collaboratively determine a proxy-ID to each of the node As and may pre-assign the proxy-ID to that node A. Following this scheme, node A does not need to receive its proxy-ID from the GA during the data-collection phase, node A may only transmit a request to GA notifying the gateway that they want to train the model.
[0087] In an example, GA then may determine a pairing -ID and/or ask all node As of a particular Type to send it their pairing-IDs that the gateway may use to determine which node B they are connecting to.
[0088] In an example, Lenovo GA may ask all UEs with high-end Qualcomm chipset to send the Cell-ID that they are associated with.
[0089] In an example, Lenovo GA may use IMEI of the UEs with high-end Qualcomm chipset. Since the network side knows which IMEI is connected to which cell it can determine the connected gNB.
[0090] In an example, GA may notify the GB that the UEs with a certain GA D want to collect data for training of their model and may send GB their pairing-IDs.
[0091] In an example, Lenovo GA notifies T-Mobile GB that UEs with GA D = 4 want to collect data for training of their models and may send their Cell-ID to the T-Mobile GB.
[0092] In an example, Lenovo GA notifies T-Mobile GB that UEs with GA D = 4 want to collect data for training of their models and may send their IMEI of that UEs to T-Mobile GB.
[0093] In an example, using the received pairing-IDs, GB may determine the node Bs who are connected to node As and may determine their Types. GB, then, may associate a proxy-ID with each of the types. Term GB D may be used to refer to this proxy-ID. If that type was previously assigned with an ID, it may use that ID, otherwise the gateway may generate a new random number which has not been previously used at this gateway for that type.
[0094] In an example, T-Mobile GB may determine that the Cell-IDs that it has received are associated with two gNB types, one group is associated with Ericsson first generation gNB and the other group is associated with Nokia second generation gNB. It may assign two
random numbers, such as GB D = 2 and GB D = 4 to Ericsson first generation gNB and Nokia second generation gNB, respectively.
[0095] In an example, GB and node Bs may collaboratively determine a proxy-ID to each of the node Bs and may pre-assign the proxy-ID to that node B. Following this scheme, node B does not need to receive its proxy-ID from the GB during the data-collection phase.
[0096] In an example, GB may notify the GA with the information on the GB D of the node B that each node A with certain Pairing-ID is connected to.
[0097] In an example, T-Mobile GB may notify Lenovo GA that a certain set of UEs with such Cell-ID/IMEI are connected to GB D = 2 and another group of them are connected to GB'D = 4.
[0098] At this stage, both sides may know that there are two groups of (node A, node B) pairs, for example
[0099] In an example, data collection and model training may be carried out for each group.
[0100] In an example, node As with similar (GA D, GB D ~) may participate in data collection and may use the training dataset. The collected data may then be used for training the encoder model for (GA D, GB D)~ . The dataset required for construction of the paired decoder model may be constructed.
[0101] In an example, the constructed dataset may be sent to node B-side with an indication that this dataset is for (GA D, GB D)~ . The dataset may be sent to GB (directly or via GA) and GB may direct it to appropriate server/node owned by the node B with that particular iD
[0102] In an example, GB may send an IP address of the server/node owned by the node B with that particular GB D, so the data of (GA D, GB D ) may be sent directly to that server/node.
[0103] In an example, the node B-side server/node may train the decoder model of the two-sided model associated with (GA D, GB D
[0104] In an example, node As with similar GA D may send their data to the node B-side indicating that this dataset is for GA D. The dataset may be sent to GB (directly or via GA) and GB may direct the portion of the datasets associated with a particular
t0 appropriate server/node owned by the node B with that particular GB D.
[0105] In an example, GB may send an IP address of the node owned by the node B with that particular GB D, so the data of (GA D, B D) may be sent directly to that server/node. Each node B type may then have the training dataset for different (GA D, B D ) if there are multiple GA Ds. The server/node owned by the node B with that particular GB D may train the decoder model for (GA D, GB D~) and may also construct the dataset required for construction of the paired encoder model.
[0106] In an example, the constructed dataset may be sent to node A-side with an indication that the dataset is for a particular (G D, GB ID)~ . The dataset may be sent to GA (directly or via GB) and then GA may direct it to appropriate server/node owned by the node A with that particular GA D .
[0107] In an example, GA may send an IP address of the server/node owned by the node A with that particular GB D, so the data can be sent directly to that server/node.
[0108] In an example, the node A-side server/node may train the encoder model of the two-sided model associated with (GA D, GB D)~ .
[0109] In an example, node A and node B may further partition the dataset into subdatasets based on parameters of the node A, pA, and/or parameters of node B, pB, and may then train separate encoder/decoder models for each sub-dataset. The resulted models trained for each sub-dataset may be represented by
GB D), pA, pB],
[0110] In an example, collected data from all Lenovo UEs with high-end Qualcomm chipset connected to Ericsson first generation gNB may have (GA D = 4, GB D = 2). Instead of trained one encoder/decoder model for the whole dataset, this data may be further partitioned based on some configuration/UE capability parameters such as #Txport/Bandwidth/carrier- frequency and different models may be trained for each group.
[0111] There may now, as a result of the above, be different pairs of encoder model and decoder model trained for different pairs of (G^1 , GB D~) . The trained models may be transferred back to the node As/node Bs so they can select the appropriate model themselves. In an example, the trained models may be saved on a server/node on the node A-side/node B-side so they can be transferred to the node A/node B based on the need of the node A/node B at each state.
[0112] Node A and node B Gateways may be located in different physical/logical locations than the node A/node Bs.
[0113] In an example, the Gateways of the NW side, e.g., T-Mobile gateway, may be located at the Access and Mobility Management Function (AMF) of the core. This node may then communicate with the gNBs or with the UE- Vendor gateway. The Gateways of the UEs may also be located at an OTT server owned by the UE manufacturer.
[0114] The above examples ensure transparency between the node A and node B using, for example, Proxy-IDs assigned to node A and node B useable during the training, and data transfer being through a gateway node or with the involvement of the Gateway node such that the Type of node A/node B does not leak to the other side.
[0115] While, above, it is described that node A first initiates the data collection and model training phase, this process may in other examples instead be initiated from the node B side. In an example, a node B (node B Type) may send their request to their gateway notifying the gateway that they want to train the model. Then GB may get pairinginformation, find the node A, determine the gateway of node A, and communicate with the determined gateways to find out the proxy-ID of the node-As. GA and GB may further facilitate data collection and communication needed during the training.
[0116] In an example, different models each associated with a particular (GA D, GB D ~) may already have been trained. Also, the encoder/decoder part of the model may have been transferred back to node A/node B respectively, and the encoder/decoder part of the model may have been stored on a server/node owned by that particular node A/node B Type respectively.
[0117] In an example, models are stored at the node A/node B. The encoder part of
4, G^ = 4) may, in an example, have been stored on all
UEs with GA D = 4, i.e., with high-end Qualcomm chipset.
[0118] In an example, the decoder part
4, G['P = 2) may be stored at the Ericsson first generation gNB and the decoder part o
4, Gj = 4) may be stored at the Nokia second generation gNB.
[0119] In an example, node A may determine its associated GA D . It may ask the node A Gateway GA for, or GA may proactively send, the associated a proxy-ID, GA D (which may have been assigned during the training) to node A.
[0120] In an example, a Lenovo UE equipped with high-end Qualcomm chipset may ask a Lenovo Gateway about its proxy-ID and receive information that it GA D = 4.
[0121] In an example, the Lenovo gateway may notify the Lenovo UE equipped with a high-end Qualcomm chipset that its proxy-ID is GA D = 4.
[0122] In an example, each time that the node A is associated with a new node B and it wants to select one of its models, node A may ask GA about the proxy-ID of the node B that the node A is currently associated with. In an example, if the GA does not have the current pairing-ID of the node A, node A may send the pairing-ID to GA .
[0123] In an example, the UE may send its current Cell-ID to the Lenovo gateway asking for the type of the connected gNB.
[0124] In cases that, for example, IMEI is the pairing-ID and assuming that Lenovo gateway knows the IMEI of each UE, the UE may ask the Lenovo gateway for the type of the connected gNB.
[0125] In an example, the UE may start this procedure after the initial connection to a gNB or after handover from one gNB to another gNB.
[0126] In an example, the UE may start this procedure after the gNB askes for the UE capabilities to check if it can support a certain AI/ML based functionality or not.
[0127] In an example, using the pairing-ID, GA may then ask GB about the type of the connected node B. It may send the GA D of the current UE to the GB .
[0128] In an example, GA may ask GB for the gNB proxy-ID of the gNB with that particular cell-ID and may say that G^°of that node A is GA D = 4.
[0129] In an example, GA may ask GB for the gNB proxy-ID of the gNB that a UE with particular IMEI is connected to and may say that GA D of that node A is GA D = 4.
[0130] In an example, GB may use the pairing-ID to determine the actual node B and then may use its internal mapping to determine GB D of the connected node B and may send it back to GA . It may also send the G^°of that node A to the gNB.
[0131] In an example, GB may find out that the connected gNB of that UE is a Nokia second generation gNB and so feedback GB D = 4 to GB .
[0132] In an example, knowing GA D and also its own GB D, the node B may determine the decoder model that should be used. In an example, node B may not find a correct match among the existing models, and may declare that the model is not available, or functionality is not supported by transmitting a message back to node A.
[0133] In an example, the gNB may know GB D = 4 and also ]that GA D = 4; therefore, it may select the decoder model of (GA D = 4, GB D = 4).
[0134] In an example, GA may send back the received GB D to the node A.
[0135] In an example, GA may send back GB D = 4 to the UE.
[0136] In an example, knowing GB D and its own GA D , the node A may determine the encoder model that should be used. In an example, node A may not find a correct match among the existing models, and may declare that the model is not available, or functionality is not supported.
[0137] In an example, the UE may know
= 4 and may also know that GB D = 4; therefore, it may select the encoder model of (GA D = 4, GB D = 4).
[0138] In an example, models may be stored at a server/node at the node A-side/node B- side. SA and SB refer to this server/node at the node A-side/node B-side, respectively.
[0139] In an example, the encoder part of (GA D = 4, GB D = 2) and (GA D = 4, GB D = 4) may have been stored on SA and SB, respectively.
[0140] In examples, SA may first determine the GA D associated with node A. Node A may know its GA D and may send it to SA, node A may ask for its GA D from GA and then may send it to SA.
[0141] In an example, each time that the node A is associated with a new node B and it wants to select one of its models, node A SA may ask GA about the proxy-ID of the node B that the node A is currently associated with. If GA does not have the current pairing-ID of the node A, node A may send the pairing-ID to GA .
[0142] In an example, using the pairing-ID, GA then may ask GB about the type of the connected node B. It may also send the GA D of the current UE to the GB .
[0143] In an example, GB may use the pairing-ID to determine the actual node B and then using its internal mapping, may determine GB D of the connected node B and send it back to GA . It may send the G^°of that node A to the gNB/SB.
[0144] In examples, SB may determine the GB D associated with node B. Node B may know its GB D and send it to SB, Node B may ask for its GB D from Gb and may send it to SB,
[0145] In an example, knowing GA D and GB D, SB may determine the decoder model that should be used and may send it to the node B. In an example, SB may not find a correct match among the existing models, and may declare that the model is not available, or functionality is not supported.
[0146] In an example, GA may send back the received GB D to SA.
[0147] In an example, knowing GB D and GA D, SA may determine the encoder model that should be used and may send it to the node A. In an example, node A may not find a correct
match among the existing models, and may declare that the model is not available, or functionality is not supported.
[0148] In an example, models are stored at the node A/node B. node A and node B may have been notified about their proxy -IDs, i.e., GA D and GB !D, respectively.
[0149] In an example, the encoder part
4, GB D = 4) may have been stored on all UEs with GA D = 4, i.e., with high-end Qualcomm chipset and these UEs may know that their proxy-ID is GA D = 4.
[0150] In an example, the decoder part o
4, GB D = 2) may be stored on all gNBs with Ericsson first generation chipsets and these gNBs may know that they have GB D = 2. Also, the decoder part
4, GB D = 4) may stored at the Nokia second generation gNB and it may know that it has GB D = 4.
[0151] In an example, node A may send its proxy-ID GA D to the node B that it is associated with. This procedure may be initiated with different conditions, e.g., each time that the node A is associated with a new node B and it wants to select one of its models.
[0152] In an example, node A with a high-end Qualcomm chipset may send GA D = 4 to the gNB.
[0153] In an example, GA and node As may collaboratively determine a proxy-ID for each of the node As and pre-assign the proxy-ID to those node As. In this example, node A may not need to ask for the proxy-ID from the GA as it has been already assigned to it.
[0154] In an example, node B, based on the received GA D, may determine the decoder model based on its own GB D . If there is no matching model, it may declare that the model is not available, or functionality is not supported by transmitting a message back to node A.
[0155] In an example, node B may be a Nokia second generation gNB with GB D = 4, and may select the decoder part of the model associated with (GA D = 4, GB D = 4).
[0156] In an example, the UE may start this procedure after the initial connection to a gNB or after handover from one gNB to another gNB.
[0157] In an example, the UE may start this procedure after the gNB askes for the UE capabilities to check if it can support a certain AI/ML based functionality or not.
[0158] In an example, GB and node As may collaboratively determine a proxy-ID for each of the node Bs and pre-assign the proxy-ID to those node Bs. In this example, node B may not need to ask for the proxy-ID from the GB as it has been already assigned to it.
[0159] In an example, node B may send back its proxy-ID GB D to the node A.
[0160] In an example, node B may be a Nokia second generation gNB and may send
GB !D = 4 to the UE.
[0161] In an example, node A, based on the received GB D, may determine the encoder model based on its own G^D . If there is no matching model, it may declare that the model is not available, or functionality is not supported.
[0162] In an example, node A may select the encoder model associated
= 4, GB D = 4) since its G^D = 4 and the received node-B proxy-ID is GB D = 4.
