RRC (Radio Resource Control) SIB (System Information Block) UAC (Unified Access Control) UE (User Equipment) UL Uplink Detailed Implementation Figure 1 An example of a communication network 100 is illustrated, such as a 5G network, a 6G network, or any other suitable type of network. Network 100 includes various different types of nodes 110, 120, and 130. The different types of nodes 110, 120, and 130 may include terminal nodes 110 and network nodes 120 and 130. Network nodes may include access nodes 120 and core network nodes 130 and / or any other suitable type of device.

[0037] Access node 120 can be configured to communicate with terminal node 110. Core network node 130 communicates with access node 120. In some examples, core network node 130 communicates with terminal node 110.

[0038] In some examples, core network nodes 130 can communicate with each other. In some examples, one or more access nodes 120 can communicate with each other.

[0039] Network 100 may be a cellular network comprising multiple cells 122. Each cell is served by an access node 120. In this example, the interface between terminal node 110 and the access node 120 providing cell 122 is a radio interface 124.

[0040] Access node 120 may include one or more cellular radio transceivers. Terminal node 110 may include one or more cellular radio transceivers.

[0041] Terminal node 110 may include user equipment (UE), energy harvesting equipment, redcap equipment, Internet of Things (IoT) equipment, Ambient Internet of Things (AIoT) equipment, or any other suitable type of equipment.

[0042] Access node 120 can be a base station. Access node 120 can be any suitable type of base station. Access node 120 can be a network entity responsible for radio transmission and reception with terminal node 110 in one or more cells. Access node 120 can be a network element in a radio access network (RAN) or any other suitable type of network.

[0043] Core network node 130 may be part of the core network. Core network node 130 may be configured to manage functions related to connectivity with terminal node 110. For example, core network node 130 may be configured to manage functions such as connectivity, mobility, authentication, authorization, and / or other suitable functions.

[0044] exist Figure 1 In the example, core network node 130 is shown as a single entity. In some examples, core network node 130 may be distributed across multiple entities. For example, core network node 130 may be cloud-based or distributed in any other suitable manner.

[0045] Network 100 can be any suitable type of network; for example, it could be a New Radio (NR) network using gNBs as access nodes. New Radio is 3GPP's designation for 5G technology. In this case, serving node 120 may include a gNB configured to provide user plane and control plane protocol termination toward terminal node 110 and / or perform any other suitable functions. The gNBs interconnect via X2 / Xn interface 126. The gNBs are also connected to core network node 130 via N2 interface 128. Other types of networks and interfaces can be used in other examples. Other types of networks could include next-generation mobile and communication networks, such as 6G networks.

[0046] Unified Access Control (UAC) is a mechanism used to determine whether a UE is allowed to access a network or a specific service. UAC parameters can be broadcast to all UEs on the cell, and a UE can have up-to-date UAC information before initiating an access attempt. The network can use UAC to restrict UE access without denying it. When a UE may need to access a 5G system, it first performs an access control check to determine if access is allowed. Access attempts can involve, for example, Multimedia Priority Service (MPS), Mission-Critical Service (MCS), or disaster situations. In the UAC check, the UE maps its access attempt to an Access Class (AC) and one or more Access Identifiers (AIs) based on mapping rules, which can be predefined in standard specifications.

[0047] The UE may have already received a blocking information, such as via a SIB1 message. For each AC, the blocking information may include a blocking factor, a blocking time, and a blocking indicator for each AI. The blocking indicator for each AI indicates whether the AI's access attempt to the AC is permitted. The blocking factor indicates the probability that a given access request can be permitted. The blocking time defines a minimum time interval, such as UAC-BarringTime, before a new access attempt can be performed after an access attempt has been blocked. The UE can then perform an access blocking check, as defined in TS 24.501 and TS 38.331.

[0048] Network Energy Saving (NES) is important for things like Figure 1The network 100 is important. NES helps improve environmental sustainability, reduce environmental impact, and provide operating cost savings. A large portion of energy consumption comes from the radio access network, and particularly from active antenna units (AAUs). The power consumption of radio access can be divided into two parts: a dynamic part, which is consumed only when data transmission / reception is in progress; and a static part, which is consumed continuously to maintain the necessary operation of the radio access equipment, even when data transmission / reception is not in progress.

[0049] Network node or access node 120 may have one or more NES modes. Different NES modes or energy-saving modes may have different levels of energy usage. For example, a first NES mode may have a first number of antenna resources in an active state, while a second NES mode may have a second number of antenna resources in an active state, wherein the first number and the second number are different. The NES mode or energy-saving mode may involve adaptation of at least one of the following: antenna resource usage, bandwidth of the active bandwidth portion (BWP), transmit power, and time (time slots occupied for DL ​​transmission).

[0050] For example, antenna resource usage can be adapted through spatial element / antenna adaptation. This adaptation aims to dynamically adapt spatial elements (e.g., using scaling factors) using scaling factors. sa The proportion of active antenna elements at network nodes is represented by ).

[0051] For example, the transmit power of a signal or channel can be adapted. This adaptation aims to use a scaling factor (e.g., sp This is used to adapt the transmit power or power spectral density (PSD) of the downlink signal to represent the PSD ratio of each transmission (Tx) between the DL transmission and the reference configuration.

[0052] For example, the bandwidth of the active BWP can be adapted. This adaptation is intended to use scaling factors (e.g., sf This is used to adapt the bandwidth of the active BWP to represent the ratio between the RF bandwidth and the maximum system BW.

[0053] For example, adaptation in the time domain aims to use scaling factors (e.g.) st This is used to adapt the time slots occupied by DL transmission to represent the active time slots occupied by data.

[0054] Let's consider devices or equipment such as energy harvesting devices, RedCap devices, IoT devices, and AIoT devices, which can be referred to as low-priority devices or low-priority user equipment (UEs). From the NES's perspective, it is inefficient for a UE (e.g., a low-priority UE) to wake up a network node in NES mode.

[0055] Examples of this disclosure provide methods and apparatus configured to perform the methods to prevent UEs (e.g., low-priority UEs) from accessing a cell employing NES technology. For example, an access control procedure is provided that can take into account different NES modes or energy-saving modes of network 100.

[0056] Figure 2 Example methods that can be implemented in the examples of this disclosure are shown. Figure 2 The method can be implemented by a device including terminal node 110 (e.g., UE) or a device within terminal node 110. For example, the device configured to perform at least the method can be one of the following: UE, low-priority UE, energy harvesting device, RedCap device, IoT device, AIoT device. Figure 3 This method can be implemented by network node 120 (e.g., gNB). The corresponding method can be executed as part of the access procedure of network 100 that can implement NES.

[0057] Figure 2 The method includes, at block 200, receiving at least one NES mode parameter from network node 120. The NES mode parameter may be an indication of the NES mode of network node 120. The NES mode parameter may include an NES prohibition factor, an NES prohibition time, and / or any other suitable parameter.

[0058] At least one NES mode parameter may include different parameters for different energy-saving modes of network node 120. Different energy-saving modes of network node 120 may include different numbers of resources of network node 102 being active or any other different type of arrangement of network node 120. For example, different NES modes or energy-saving modes may include at least a first mode (e.g., mode 1) and a second mode (mode 2), wherein in the first mode the number of active resources at network node 120 is higher than in the second mode. For example, in mode 1, 75% of the network node's resources are active; in mode 2, 50% of the network node's resources are active; and in mode 3, 25% of the network node's resources are active.

[0059] NES mode parameters can be associated with specific types of devices. Different types of devices can be or can be included within a UE, energy harvesting device, RedCap device, IoT device, AIoT device, or any other suitable type of device. Different NES mode parameters associated with different types of devices can take into account different priority levels for the device type. For example, a device or equipment such as an energy harvesting device, RedCap device, IoT device, or AIoT device can be referred to as a low-priority device or a low-priority UE.

[0060] In some examples, at least one NES mode parameter may include access class (AC) and / or access identifier (AI) specific information. This allows different NES mode parameters to be associated with different access classes and / or different access identifiers.

[0061] At least one NES mode parameter can be received in any suitable format. In some examples, at least one NES mode parameter can be received as additional information for a Unified Access Control (UAC) parameter.

[0062] At least one NES mode parameter can be received in any suitable signaling. In some examples, the NES mode parameter can be received in broadcast messages, UAC messages, Master Information Block (MIB), or System Information Block (SIB).

[0063] At block 202, the method includes receiving at least one evaluation criterion from network node 120 for the device to determine whether to initiate an access procedure with network node 120. The evaluation criterion may include mathematical operations. The mathematical operations may be based on at least one NES mode parameter. The mathematical operations may be performed by the device at block 204. An example of a mathematical operation is given below.

[0064] The access procedure covered by the evaluation criteria can be any type of access procedure. The access procedure can be a random access procedure, a Radio Resource Control (RRC) connection restoration procedure, or any other suitable type of access procedure.

[0065] At least one evaluation criterion can be received in any suitable signaling. In some examples, NES mode parameters can be received in broadcast messages, UAC messages, Master Information Block (MIB), or System Information Block (SIB).

[0066] The reception of NES mode parameters 200 and the reception of evaluation criteria 202 are in Figure 2 They are displayed as separate boxes. In other examples, they can be received together, such as in the same signaling or the same message. If the NES mode parameters and evaluation criteria are received separately, they can be received in any order. That is, the NES mode parameters can be received before the evaluation criteria, or the evaluation criteria can be received before the NES mode parameters.

[0067] At box 204, the method includes determining whether to initiate an access procedure with a network node. The determination is based on at least one NES mode parameter and at least one evaluation criterion. The determination may include performing one or more mathematical operations defined by the evaluation criterion, wherein the at least one NES mode parameter is used in the one or more mathematical operations.

[0068] If at least one evaluation criterion is satisfied at box 204, the device will initiate an access procedure with network node 120. The evaluation criterion is considered satisfied if the output of the mathematical operation meets the requirements defined by the evaluation criterion.

[0069] If it is determined at box 204 that at least one evaluation criterion is not met, the device determines a time period. The time period can be based on the NES prohibition time. An example of calculating the timer period is given below. The NES prohibition time can be one of the NES mode parameters received at box 200. The device will wait until the determined time period expires before making another attempt to access the cell provided by network node 120.

[0070] In some examples of this disclosure, the method may further include receiving an update to at least one NES mode parameter of network node 120. The NES mode parameter may be updated by network node 120 due to changes in network load. The change in network load may be the current network load or an upcoming network load. Updates to the NES mode parameter can be received using any suitable signaling. The apparatus can then update or replace at least one NES mode parameter based on the received update. The apparatus can then use the updated or replaced NES mode parameter in evaluation criteria.

[0071] In some examples, the NES mode parameters received from the network node may include an indication of the NES mode. For example, the parameter may indicate whether the network node is using mode 1, in which, for example, 75% of the network node's resources are active; mode 2, in which, for example, 50% of the network node's resources are active; or mode 3, in which, for example, 25% of the network node's resources are active. Other modes with different percentages may be used in other examples. In this case, the device may be able to perform at least a partial determination of at least one of the NES prohibition factor or the NES prohibition time based on the indicated network power saving mode.

[0072] The determination of the NES prohibition factor or NES prohibition time by the device can also be based on other criteria. These other criteria may include device-specific criteria. This can provide the device with improved flexibility. For example, the NES prohibition factor or NES prohibition time can be determined at least in part based on the device's buffer state. In this case, the device can determine whether its buffer is full or above a threshold level. If the buffer is full or above a threshold level, the device can use the NES prohibition factor and / or NES prohibition time to allow transmission to avoid any data loss. If the buffer is not full or below a threshold level, the device can use the NES prohibition factor and / or NES prohibition time to restrict access until more resources are available at the network node. The device can also consider its Quality of Service (QoS) requirements. For example, if the QoS requirements are less stringent and the buffer is empty, not full, or below a threshold level, the device can use the NES prohibition factor and / or NES prohibition time to restrict access until more or all resources are available at the network node.

[0073] Figure 3 Example methods that can be implemented in the examples of this disclosure are shown. Figure 3 The method can be implemented by means including network node 120 (e.g., gNB) or means within network node 110. For example, the means configured to perform at least the method can be a network node, such as gNB. Figure 3 The method is Figure 2 The corresponding method for the method.

[0074] At box 300, the method includes determining at least one NES mode parameter of network node 120.

[0075] At box 302, the method includes determining at least one evaluation criterion for the device (UE) to determine whether to initiate an access procedure with network node 120.

[0076] At block 304, the method includes transmitting at least one NES mode parameter of network node 120 and at least one evaluation criterion for the device to the device. The NES parameter and evaluation criterion can be transmitted to the device to enable the device to perform... Figure 2 The method shown.

[0077] NES parameters and evaluation criteria can be transmitted using any suitable signaling, such as broadcast messages, UAC messages, Master Information Block (MIB), or System Information Block (SIB).

[0078] NES parameters and evaluation criteria can be transmitted separately or together, for example, in the same signaling or the same message. If NES mode parameters and evaluation criteria are transmitted separately, they can be transmitted in any order. That is, NES mode parameters can be transmitted before evaluation criteria, or evaluation criteria can be transmitted before NES mode parameters.

[0079] Figure 4 An example signaling diagram that can be used in the examples of this disclosure is shown. In this example, signaling occurs between the UE and the gNB. Other types of terminal nodes 110 and network nodes 120 can be used in other examples. For example, the UE can be a low-priority UE as described above.

[0080] Figure 4 The example method shown can be used to adjust the UAC process. The example method can also be used to restrict network access by using one or more NES mode parameters and corresponding evaluation criteria.

[0081] At box 400, the method includes transmitting one or more NES mode parameters and one or more evaluation criteria from the gNB to the UE. The NES mode parameters and one or more evaluation criteria may be transmitted in a broadcast message, UAC information, Master Information Block (MIB) or System Information Block (SIB), or in any other suitable signaling.

[0082] In the example where NES mode parameters and one or more evaluation criteria are transmitted along with UAC information, the signaling at box 400 may also include a prohibition factor, prohibition time, and prohibition indicator for each Access Identifier (AI). The NES mode parameters and evaluation criteria may be provided as additional information to the prohibition factor, prohibition time, and prohibition indicator.

[0083] NES mode parameters may include NES prohibition factor, NES prohibition time, and / or any other suitable parameters or combinations thereof.

[0084] The NES mode parameters can differ for different NES modes of the gNB. NES mode parameters can be set to implement different restrictions on network traffic for different NES modes. For example, a first NES mode may include the gNB using a sleep mode with a first duration, and a second NES mode may include the gNB using a sleep mode with a second duration, where the second duration is longer than the first duration. In this example, NES parameters, such as the NES prohibition factor, can be set lower for the second NES mode to reduce access requests to the gNB. For example, configuring the NES prohibition factor to a value of '0' will result in all access control checks resulting in blocked access attempts.

[0085] In some examples, a first NES mode may include a first number of resources being active, and a second NES mode may include a second number of resources being active, where the second number is less than the first number. In these examples, NES parameters, such as the NES prohibition factor, may be set lower for the second NES mode to reduce access requests to the gNB. For example, configuring the NES prohibition factor to a value of '0' will result in all access control checks resulting in blocked access attempts.

[0086] In some examples, the NES blocking time parameter can be different for different NES modes. For example, a higher NES blocking time can be set to increase the UE's waiting time, thereby reducing access requests to the gNB.

[0087] In some examples, the NES mode parameters can be applied to all UEs. This can be the case in examples where the UE is active at the gNB or where available resources are very limited.

[0088] In some examples, different NES mode parameters can be associated with different types of UEs. For instance, some UEs may be classified as low-priority UEs and may have higher levels of restrictions compared to other non-low-priority UEs. NES mode parameters may apply to low-priority UEs but not to other types of UEs. A UE may have multiple priority levels, and each priority level may have multiple NES mode parameters. The priority level of a UE may be determined based on active resources at the gNB and / or any other suitable factors.

[0089] At box 402, the gNB can send updated NES mode parameters. NES mode parameters can be updated based on changes in network load. NES mode parameters can be updated to limit network traffic within a certain limit. Changes can be based on current or upcoming network load. Changes in NES mode parameters can indicate changes in the NES mode used by the gNB. The network can adjust NES mode parameters to stop UE access and keep network traffic below the limit.

[0090] If the gNB does not determine the NES mode parameters that need to be updated, box 402 can be omitted, and the UE can use the NES mode parameters received at box 400 to perform the method.

[0091] Updated NES parameters can be transmitted in any suitable signaling. These parameters can be transmitted along with other information that enables the UE to determine whether it is allowed to access the cell. In some examples, updated NES parameters can be transmitted using SIB1.

[0092] At box 404, the UE determines to execute a connection request. The connection request allows the UE to switch from IDLE / INACTIVE mode to CONNECTED mode.

[0093] Once the UE has determined to execute a connection request, at box 406, the UE checks evaluation criteria to determine whether to initiate an access procedure, such as a random access procedure. The UE can map its access attempt to an AC or one or more AIs. The UE can use NES mode parameters received at boxes 400 or 402 in the evaluation criteria. In some examples, one or more additional parameters may also be used in the evaluation criteria. For example, one or more UAC parameters may also be used.

[0094] Evaluation criteria can include any suitable mathematical operations. As an example, an evaluation criterion could include the UE generating random numbers uniformly distributed between 0 and 1. And evaluation equation 1.

[0095] Equation (1) If the random number is less than uac_BarringFactor and If the product of these two values ​​is true, the access attempt is allowed. Otherwise, the access attempt is denied. In this example, it is uac_BarringFactor or... A configuration value of '0' means that all checks of the evaluation criteria will result in access attempts being blocked.

[0096] Depending on the network implementation and NES requirements, other equations or mathematical operations can be used in the evaluation criteria. In some examples, such as Equations 2 and 3, the evaluation criteria can be based on a combination of the NES prohibition factor and the uac_BarringFactor.

[0097] / 2, Equation (2) Equation (3) In some examples, such as Equation 4, the evaluation criteria can be based solely on the NES prohibition factor without using any other factors or parameters.

[0098] Equation (4) Other evaluation criteria may also be used in the examples disclosed herein.

[0099] In some examples, the UE can select the evaluation criteria to use based on either NES mode or power saving mode. For example, in the first NES mode, the evaluation criteria may include Equation 1, and in the second NES mode, the evaluation criteria may include Equation 2 or any other suitable mathematical operation.

[0100] If the evaluation criteria are met, the process proceeds to box 408. The connection request is not blocked, and the UE can determine whether to initiate an access procedure with the gNB. The UE can send a connection request to the gNB at box 410. For example, the UE can initiate a random access procedure with the gNB.

[0101] If the evaluation criteria are not met, the process proceeds to box 412. The connection request is denied, and the UE determines not to initiate an access procedure with the gNB. The UE avoids initiating an access procedure with the gNB. The UE does not send a connection request to the gNB at this time. Instead, the denial period is calculated at box 414. The denial period can define the duration for which the UE considers the gNB's cell to be denied for the corresponding access category. The denial period can be determined by any suitable timer (e.g., T390).

[0102] The prohibited time period can be calculated using appropriate mathematical operations from the evaluation criteria and any suitable NES mode parameters (such as NES prohibition time). The mathematical operations can also use any other suitable parameters, such as uac_BarringTime. Equation 5 provides an example of the mathematical operations that can be used to determine the prohibited time period.

[0103] Equation (5) Depending on the network implementation and NES requirements, other equations or mathematical operations can be used to calculate the prohibited time period. In some examples, such as Equation 6, the evaluation criteria can be based on a combination of the NES prohibition factor and uac_BarringTime.

[0104] Equation (6) In some examples, such as Equation 7, the prohibited time period can be calculated based solely on the NES prohibition factor without using any other factors or parameters.

[0105] Equation (7) For example, configuring the NES blocking time to a value close to '0' means that the UE is allowed to send new connection requests without waiting. Therefore, a higher NES blocking time may result in longer waiting times for the UE. For instance, a higher NES blocking time can be set to increase UE waiting time, thereby reducing access requests to the gNB.

[0106] At box 416, the UE waits for the prohibited period to expire. After the prohibited period expires, the process can return to boxes 400 or 402. The UE can then make another attempt to access the cell provided by the gNB after the prohibited period expires. In some examples, if the UE is within the coverage area of ​​a cell provided by another network node, the UE can attempt to access that other network node.

[0107] If the prohibited period is close to 0, the UE can send a connection request after the prohibited period expires. If the prohibited period is greater than 1, the UE can send a connection request after the gNB has disabled the current NES mode.

[0108] Figure 5 and Figure 6 An example model network and the results obtained using that model are shown to indicate the power savings that can be achieved using the examples of this disclosure. The model is used to obtain... Figure 6 The equation shown is just an example, and other equations and models can be used for other types of network nodes.

[0109] In these examples, the energy consumed by the receiver can be modeled as the energy consumed by components maintaining necessary operation plus the energy consumed by the decoding phase corresponding to Rx activity. Power consumption of the gNB in ​​active uplink (UL) state. It can be represented as shown in Equation 8.

[0110] Equation (8) in It is the ratio of active transceiver units, which can be expressed as shown in Equation 9.

[0111] Equation (9) in, This refers to the power consumption of the active transceiver unit. It is the power saved by the micro-sleep function of the active transceiver unit, and This includes additional factors such as decoding power consumption.

[0112] It can be assumed that decoding power consumption increases with data rate. Data rate can be correlated with encoding rate. Related. The relationship between the data rate and the power consumed by the decoder can be described using a linear function model, as shown in Equation 10.

[0113] Equation (10) in It is decoder-specific and models decoder efficiency.

[0114] Expected total uplink rate The NES gain can be defined using Equation 11. Equation (11) in It is the power consumption of the active UL state with the maximum load and active UE.

[0115] It can be assumed that the UE has a (limited) queue buffer to store network layer data. It can represent the first Each UE in the time slot The queue backlog during this period evolves according to Equation 12. Equation (12) in , It is an achievable rate, and Indicates average arrival rate The data has arrived.

[0116] Figure 5 A network 100 is schematically shown, which includes a gNB 500 that transmits data to multiple UEs 502. Figure 5 The example shows three UEs: 502-1, 502-k, and 502-K, but any number of UEs can be used. Figure 5 The queue backlogs 504-1 and 504-K for the corresponding UEs are also shown (as examples).

[0117] In this model, it is assumed that the access denial check involves UE 502 generating uniformly distributed random numbers. And the value of the network configuration is evaluated using equation q. Equation (1) If the random number is less than this value, the access attempt is allowed. Otherwise, the access attempt is blocked at the current time. Access blocking timers such as timer T390 are not considered for this model.

[0118] Table 1 provides the methods used to obtain... Figure 6 The simulation results shown indicate the parameter assumptions made by the model. This example illustrates three different NES modes: NES mode 1, where the network has 75% available resources, resulting in a 25% reduction in system limitations; NES mode 2, where the network has 50% available resources, resulting in a 50% reduction in system limitations; and NES mode 3, where the network has 25% available resources, resulting in a 75% reduction in system limitations.

[0119] Table 1 Figure 6 It shows the use of Figure 5The graphs in Table 1 show the network traffic changes over time for the example system and parameters. Graph 600 shows the traffic changes without using UAC ("Without UAC"), graph 602 shows the traffic changes with UAC ("With UAC"), graph 604 shows the traffic changes using NES Mode-1 ("Proposed NES Mode-1"), graph 606 shows the traffic changes using NES Mode-2 ("Proposed NES Mode-2"), and graph 608 shows the traffic changes using NES Mode-3 ("Proposed NES Mode-3").

[0120] Table 2 provides an indication of power consumption for each mode and energy savings for the normalized network.

[0121]

[0122] Table 2 In the examples disclosed herein, when network 100 identifies that traffic exceeds system limits, the network can use NES mode parameters and evaluation criteria to apply limits to the UE in order to keep traffic below system limits. The use of NES mode parameters and evaluation criteria can improve network energy savings and allow network node 120 to have longer sleep durations and / or fewer active resources at the gNB. For example, NES mode-3 shown in Table 1 provides up to 72% NES compared to the baseline scenario.

[0123] The results above represent one possible example, and these results may scale differently for different system configurations and NES requirements. However, the fundamental relationships between power consumption, achievable speeds, and network energy savings remain valid.
