Description

Technical Field

[0001] This disclosure relates to the field of wireless communications, and more specifically to measurement configurations of user equipment (UE) in idle or inactive modes. Background Technology

[0002] Some abbreviations that may be found in the specification and / or figures are defined hereafter. 3GPP Third Generation Partnership Project 5G NR (Fifth Generation New Radio) CA carrier aggregation CN Core Network DC Dual Connection gNB Next Generation Node B NR New Radio (5G) RAN (Radio Access Network) RRC Radio Resource Control RNA RAN Notification Region SIB System Information Block TA tracking area UE User Equipment

[0003] Based on the current 3GPP (3rd Generation Partnership Project) standardization, there are three Radio Resource Control (RRC) states: RRC_IDLE, RRC_INACTIVE, and RRC_CONNECTED. After a User Equipment (UE) powers on, it establishes a connection with the network to perform functions such as, but not limited to, data transmission, or making or receiving voice calls. In certain situations, such as reduced activity from or related to the UE, the network can command the UE to switch to RRC_INACTIVE or RRC_IDLE. When the UE is not actively sending or receiving data, it typically switches to an idle or inactive mode to conserve power. However, even in these low-power states, certain network tasks (such as cell reselection, measurement reporting, and system information acquisition) are necessary to maintain seamless connectivity and ensure optimal network performance.

[0004] Therefore, while in RRC_IDLE or RRC_INACTIVE, the UE can perform Radio Resource Management (RRM) measurements on its camped cell and a list of neighboring cells or carriers, allowing the UE to determine whether the network is optimal in its current cell or in one of its neighboring cells. Thus, the UE can either remain in its current cell or reselect to one of its neighboring cells. In the case of carrier aggregation (CA) and / or dual connectivity (DC), where the network node (NW) can offload UE traffic to more cells by adding more carriers, the UE can report measurements to the NW when it is switched to RRC_CONNECTED, enabling the NW to quickly determine which neighboring cells are added as secondary cells (SCell) or primary-secondary cells (PSCell) in CA and DC, respectively.

[0005] Traditionally, UEs in idle or inactive modes can rely on information maintained from broadcast system information (such as System Information Blocks (SIBs)) to find the configurations needed to perform basic tasks such as cell reselection. This approach leads to inefficient use of network resources and requires system information scheduling. Furthermore, broadcast configurations are generic and not tailored to the specific needs or capabilities of individual UEs. Additionally, UEs may consume unnecessary power to process irrelevant broadcast configurations, further reducing battery life—a critical issue for mobile devices.

[0006] Therefore, even in idle or inactive mode, the UE may be instructed to perform measurements based on measurement configurations provided in one or more System Information Blocks (SIBs) from the network node. Furthermore, periodically sending SIBs may not be power-optimal for the network node. Similarly, for a UE in RRC_IDLE or RRC_INACTIVE mode, reading a sent SIB would be counterintuitive in terms of power consumption, where the measurement configuration in the sent SIB can be cell-specific rather than UE-specific. Summary of the Invention

[0007] Aspects relating to the exemplary embodiments disclosed herein are set forth below. It should be understood that these aspects are not intended to limit the scope of this disclosure. In fact, this disclosure may cover various aspects not set forth below.

[0008] In one example embodiment of this disclosure, a user equipment (UE) (120) for wireless communication includes at least one processor (1204) and at least one memory (1202) storing instructions thereon that, when executed by the at least one processor (1204), cause the user equipment (120) to: receive (202, 301) a signaling message from a network node (110A) in a first cell (130) before entering an idle or inactive mode, the signaling message including a user equipment (UE) specific measurement configuration (202(a)) including one or more carriers to be measured in the idle or inactive mode, and to perform (206, 302) a measurement of the one or more carriers in the idle or inactive mode according to the UE measurement configuration (202(a)).

[0009] In one example embodiment of this disclosure, a network node (110) for wireless communication includes: at least one processor (1104) and at least one memory (1102) storing instructions thereon that, when executed by the at least one processor (1104), cause the network node (110) to: send a (202, 401) signaling message to the user equipment (UE) (120) when or before the user equipment (UE) (120) enters an idle or inactive mode, the signaling message including a user equipment (UE) (120) specific measurement configuration (202a) including one or more carriers to be measured in the idle or inactive mode; and broadcast (205, 402) a cell common measurement configuration in its cell (130, 140).

[0010] In another example embodiment, a method for wireless communication is disclosed. The method is performed by a user equipment (120). The method includes: receiving (202, 301) signaling messages from a network node (110A) in a first cell (130) upon or before entering an idle or inactive mode. These signaling messages include a user equipment (UE) (120) measurement configuration (202(a)) including one or more carriers to be measured in the idle or inactive mode, and performing (206, 302) measurements of the one or more carriers in the idle or inactive mode according to the UE (120)-specific measurement configuration (202(a)). In another example embodiment, a method for wireless communication is disclosed. This method is performed by a network node (110). The method includes: sending a (202, 401) signaling message to the user equipment (UE) (120) (when or before the user equipment (UE) (120) enters an idle or inactive mode, the signaling message including a user equipment (UE) (120) specific measurement configuration (202a) including one or more carriers to be measured in the idle or inactive mode; and broadcasting a (205, 402) cell common measurement configuration in its cell (130, 140).

[0027] In the following examples, different example embodiments will use communication network architectures based on 3GPP standards for communication networks (such as 5G NR or 6G (sixth generation)). Examples of communication networks to which the examples can be applied are described as examples of the embodiments; however, the example embodiments are not limited to such architectures.

[0028] Figure 1 An example wireless communication network 100, in which an example embodiment of the present disclosure may be implemented, is shown. The wireless communication network 100 includes at least the following: network nodes 110A / 110B and user equipment (UE) 120.

[0029] UE 120 can be any wireless communication device capable of transmitting and receiving radio signals. UE 120 can be used to communicate with a radio access network (RAN) via an uplink channel. Non-limiting examples of UE 120 include smartphones, tablets, laptops, etc. UE 120 can be interchangeably referred to as a mobile device, mobile terminal, mobile station (MS), radio transceiver unit (WTRU), or by other names.

[0030] Network node 110 (e.g., network node 110A / 110B) may be referred to by other names in some implementations, such as radio access network (RAN) node, next-generation NodeB (gNB), base station, radio unit, etc. Network node 110 can communicate with UE 120 according to one of a variety of Radio Point Access Technologies (RATs) and can be part of a radio access (RAN). Network node 110 can be part of the RAN and can communicate with UE 120 via a downlink channel. UE 120 can access the communication network and receive services from it via network node 110.

[0031] In the wireless communication network 100, there may be areas of radio coverage (referred to as "cells"). Each cell 130 / 140 may be supported by a network node 110. A UE 120 may have a source cell 130 (also referred to as a "serving cell"), wherein the UE 120 is associated with a network node 110A (i.e., the source network node) serving that source cell 130. Figure 1 UE 120 can be in a connected state (e.g., RRC_ACTIVE) or a disconnected state (e.g., RRC_IDLE or RRC_INACTIVE). UE 120 can be considered to be camped on source cell 130.

[0032] In the first cell (130), the network node (110) can send a signaling message to the UE (120). This message may contain a UE-specific measurement configuration detailing one or more carriers to be measured during the UE's idle or inactive state. Based on this configuration, the UE (120) performs measurements on the specified carriers without relying on broadcast system information (such as System Information Blocks (SIBs)). This configuration allows the UE (120) to prioritize carrier measurements, optimize power consumption, and enhance connectivity. The network node (112) can be caused to send updates to the measurement configuration in response to tracking area updates, RAN notification area updates, or other signaling messages received from the UE.

[0033] although Figure 1 A certain number of entities within the wireless communication network 100 are shown, but any reasonable number of these entities may be included in the wireless communication system 100.

[0034] As used herein, the terms “user equipment” (UE) and “network node” are not specific to or otherwise limited to any particular radio access technology (RAT) unless otherwise stated.

[0035] Figure 2A and 2BThe diagram illustrates the operational flow in a wireless communication network 100 involving a user equipment (UE) (120) and two network nodes: a first network node (110A) and a second network node (110B). The diagram shows the transitions and processes that occur when the UE moves from a connected state with the first network node (110A) to an idle or inactive state, and finally reselects to the second network node (110B).

[0036] Figure 2A Step (201): The UE is connected to the first network node 110A.

[0037] The UE (120) may begin in an “RRC_CONNECTED” connected state with a network node, such as a first network node (110A) . In this state, the UE (120) can actively communicate with the first network node (110A) for data transmission and reception and control signaling. The RRC_CONNECTED state provides continuous interaction between the UE and the network for tasks such as mobility management, resource allocation, and data processing. During this time, the UE can be fully synchronized with the network, and measurement tasks can be executed according to instructions from the serving node.

[0038] Step (202): An RRC release message with the configuration to be measured during idle or inactive states.

[0039] Before or during the transition to an idle or inactive state, the UE can receive an RRC Release message, or an RRC Release message with suspendConfig, from the first network node (110A) to transition the UE to the idle or inactive state, respectively. This message also includes a UE-specific measurement configuration (202a). This configuration can be customized for the UE based on its capabilities, operational requirements, and network conditions. It can specify one or more carriers that the UE should measure during its idle or inactive state. The use of customized configuration reduces reliance on broadcast information and enhances the efficiency of measurement and mobility procedures.

[0040] The configuration may include details such as measurement intervals and frequencies, priority indicators for specifying carriers, and specific criteria for cell reselection and reporting requirements. The UE (120)-specific measurement configuration may be received from the first network node (110A) as part of an RRC release or an RRC release (202) with suspendConfig to transition the UE to an idle or inactive state, respectively. Message (202) and the UE (120)-specific measurement configuration specify one or both of the following: when the measurement will be performed, or whether the configuration is applicable to cell reselection, enhanced early measurement reporting (eEMR), or both.

[0041] The UE (120) specific measurement configuration may also include a priority indicator (206) that causes the user equipment (120) to prioritize the received configuration over the broadcast configuration and, where applicable, skip processing the broadcast configuration.

[0042] Step (203): The UE and the first network node 110A enter an inactive state together.

[0043] The UE can transition to an idle or inactive state along with the first network node (110A). This state conserves power by reducing activity while maintaining minimal connectivity. Unlike the RRC_CONNECTED state, the UE in this state does not engage in continuous data exchange, but can still monitor the network for specific instructions or conditions requiring operation. Therefore, the UE enters an inactive state along with the first network node 110A.

[0044] Step (204) The UE does not read the broadcast information (SIB 1-5).

[0045] In idle or inactive states, the UE (120) can operate without relying on broadcast system information blocks (SIB1-SIB5) from the first network node (110A). Therefore, the UE does not read broadcast information (SIB1-5). This deviates from conventional methods, where the UE typically needs to process a large amount of broadcast configuration. By skipping broadcast information, the UE (120) minimizes processing overhead and power consumption. This can be beneficial in dense network environments, as frequent broadcast updates can overwhelm a UE in a low-power state.

[0046] Step (205): The UE uses a simplified common measurement configuration shared in the RRCRelease message stored in SIB1.

[0047] The RRC Release message (110A) provided by the network node includes a simplified common configuration for the User Equipment (UE) (120). This common configuration is designed to enable the UE to efficiently perform necessary measurement and mobility-related tasks during idle or inactive states without relying on a large amount of broadcast information. Here, the UE can use a simplified common measurement configuration shared in the RRC Release message stored in SIB1. This minimizes the UE's power consumption and processing overhead, especially in dense network environments; specifies minimum parameters for carrier measurements, such as prioritized frequency bands or measurement intervals; and provides rules for basic tasks such as cell reselection and enhanced early measurement reporting (eEMR). The UE can apply this configuration to continue seamless operation in idle or inactive modes without requiring additional network signaling or updates.

[0048] Figure 2B Step (206): The UE performs IDLE / INACTIVE mode measurements based on the configuration received in step 202.

[0049] Using the configuration received in step (202), the UE (120) performs IDLE / INACTIVE mode measurements, including cell reselection measurements. These measurements may involve evaluating the signal strength, quality, and other parameters of neighboring cells, including those managed by the second network node (110B). The UE can prioritize carriers specified in the configuration to ensure efficient and accurate measurements. Therefore, this step highlights one of the advantages of UE-specific configurations, as the measurements are tailored to the UE's capabilities and network requirements, meaning the UE does not waste resources measuring irrelevant carriers or processing unnecessary broadcast information. Without reading the broadcast information (204) to find the UE (120)-specific measurement configuration, the UE (120) can perform cell reselection measurements on one or more carriers in idle or inactive mode based on the UE (120)-specific measurement configuration (see step 203).

[0050] Figure 2B Step (207): UE reselects to a cell.

[0051] exist Figure 2B At step 207, the user equipment (UE) (120) can reselect to a new cell managed by the second network node (110B). This step indicates that the UE decides to reselect from its current cell to a more suitable cell based on predefined criteria such as signal strength, quality, or other network-defined parameters.

[0052] Figure 2B Step (208): The UE and the second network node 110B are in the IDLE / INACTIVE state together.

[0053] exist Figure 2B At step 208, the user equipment (UE) (120) can transition to an idle or inactive state within the new cell managed by the second network node (110B). Therefore, the cell reselection process and the operational framework for UE integration into the new cell can be performed here. In other words, the UE is now in an IDLE / INACTIVE state together with the second network node 110B.

[0054] If the UE reselects to a second node, for which the UE does not have a UE-specific measurement configuration—as provided in step 202 from the UE's last serving cell—that relies on detailed broadcast information, the UE (120) can utilize a simplified common measurement configuration. This configuration can also be embedded in SIB1 or lightweight SIBx. Without requiring additional signaling or processing, this common configuration includes the necessary parameters for carrier measurement and mobility procedures, ensuring that the UE (120) has minimal relevant information.

[0055] Figure 2B Step (209): The UE extracts only the common / minimum configuration (e.g., SIB1 or lightweight SIBx) broadcast from the new cell.

[0056] Figure 2B Step 209 refers to the user equipment (UE) (120) using a common configuration for its operation in a new cell managed by the second network node (110B). Here, the UE only extracts the common / minimum configuration (e.g., SIB1 or lightweight SIBx) broadcast from the new cell.

[0057] Common configurations include basic operating parameters broadcast by the new cell, such as: System Information Block 1 (SIB1): providing necessary network information such as cell identifier, frequency band support, and access parameters; Lightweight System Information Block (SIBx): containing reduced critical information required for idle / inactive mode operation. These parameters may be common to all UEs within the cell and are optimized for energy-saving operation.

[0058] Figure 2B Step (210): Based on the common configuration, the UE performs IDLE / INACTIVE mode measurements at the new cell.

[0059] Figure 2B Step 210 represents the phase in which the User Equipment (UE) (120) operates in an idle or inactive state within the new cell after successfully reselecting to a new cell managed by the second network node (110B). This step marks the completion of the cell reselection process and the UE's adaptation to the new cell environment. Common configuration ensures that the UE can perform critical tasks, such as monitoring the network for paging or updates. Continuing carrier measurements for cell reselection or enhanced early measurement report (eEMR) reduces signaling overhead by eliminating the need for individual UE-specific configurations at this stage. Common configuration also allows the UE to operate efficiently while conserving energy. The UE can skip processing unnecessary broadcast information and focus only on the critical details required to maintain connectivity and mobility readiness. The UE can periodically listen for broadcast information, paging, or specific instructions from the network to ensure it can re-enter an active state when needed. Additionally, the UE can operate based on the minimum or common configuration received during the reselection process.

[0060] Figure 3 The processing flow for a user equipment (UE) (120) in a wireless communication system is illustrated, with particular focus on its behavior during transitions to idle or inactive modes and the execution of measurement configurations. The figure depicts the sequence of operations performed by the UE to perform carrier measurements, including listening to the SIB, paging, or initiating a switch to an RRC connection, while optimizing power consumption.

[0061] Listening to SIBs, paging, or initiating a transition to an RRC connection (301): The UE can monitor system information blocks (SIBs) broadcast by the network, such as SIB1 or lightweight SIBx, to gather necessary information about the serving cell and neighboring cells. This data may help the UE keep synchronized with the network and prepare for measurement and mobility tasks. The UE can also listen for paging messages sent by the network to receive instructions or updates regarding its status or transition. Paging ensures that the UE maintains a connection with the network in idle or inactive modes while conserving power. If triggered by network or user activity, the UE can use the information from the SIBs and paging to prepare for a possible transition to the RRC_CONNECTED state.

[0062] Receive Measurement Configuration (302): Before or during the entry into idle or inactive mode, the UE (120) receives a signaling message, such as an RRC release message, from the network node (110A). This message contains a UE-specific measurement configuration that specifies one or more carriers that the UE should measure during the idle or inactive state. This configuration can be customized for the UE's capabilities and network requirements to ensure efficient resource utilization. The UE-specific measurement configuration (120) can be configured based on the capabilities of the user equipment, including one or more of supported frequency bands and power consumption capabilities.

[0063] Application Measurement Configuration (303): The UE can apply the received configuration during idle or inactive modes without processing broadcast system information, such as System Information Blocks (SIB1–SIB5). The UE can read broadcast information including System Information Blocks (SIBs), where SIB1 can include one or more of the following: SIB2, SIB3, SIB4, and SIB5. Additionally, the configuration can include parameters such as the carrier frequency to be measured, measurement interval and priority, and conditions for Enhanced Early Measurement Report (eEMR).

[0064] Based on this configuration, the UE can perform measurements on specified carriers. These measurements can be crucial for tasks such as evaluating neighboring cells for reselection, collecting data for eEMR, and enabling the network to make informed decisions regarding mobility management. Therefore, the UE optimizes its power consumption by avoiding unnecessary broadcast information processing and focusing only on the carriers and parameters specified in the configuration. When the UE transitions back to the connected (RRC_CONNECTED) state, it can report the measurement results to the network node. Thus, based on the received configuration, upon transitioning to RRC_CONNECTED, the user equipment (120) can be enabled to report (212) the measurement results to the network node (110 B). These results allow the network to refine its configuration and improve overall system performance.

[0065] Figure 4 The operation of the network node (110) is shown, and the role of the network in configuring the user equipment (UE) (120) for efficient operation during idle or inactive states is explained in detail.

[0066] Step 401: Sending UE-Specific Measurement Configuration: In step 401, the network node (110) may be responsible for sending a customized signaling message to the UE (120). This message may contain a UE-specific measurement configuration that enables the UE to effectively perform carrier measurements in idle or inactive modes. The network node may send signaling messages, such as RRC release messages, to the UE before or when the UE transitions to idle or inactive modes. This message may include detailed parameters for carrier measurements, designed to align with the UE's capabilities and network requirements. The measurement configuration (202a) may also be sent as part of an RRC Release (202) with a suspend configuration. The UE (120)-specific measurement configuration may also be sent as part of the RRC release message (202), and the UE (120)-specific measurement configuration may specify one or both of the following: when the measurement will be performed, or whether the configuration is applicable to cell reselection, enhanced early measurement reporting (eEMR), or both.

[0067] The configuration can be UE-specific and specifies the carrier or frequency to be measured, the priority rules for carrier measurements, the conditions for cell reselection or enhanced early measurement report (eEMR), and the duration for which the configuration remains valid for one or more carrier measurements. The UE (120)-specific measurement configuration includes priority rules that allow the user device (120) to apply (206) the received configuration instead of the broadcast configuration (205) during idle or inactive modes.

[0068] This configuration can be customized based on the UE's hardware capabilities, such as supported frequency bands and power consumption profiles. This ensures that the configuration is optimized for both network performance and UE efficiency. The measurement configuration can also be UE (120) specific and includes a specified duration during which the UE (120) specific measurement configuration (202a) remains valid for one or more carrier measurements. The measurement configuration can be optimized based on one or more of the following: the most recent measurement report when the UE is in RRC_CONNECTED, or auxiliary information received from the user equipment (120).

[0069] Step 402: The cell common measurement configuration can be broadcast by the network node (110) within its cells (130, 140). This configuration may include information for idle or inactive states, such as parameters for cell reselection and Early Measurement Report (EMR). The UE can process minimal broadcast information, such as SIB1 or Lightweight System Information Blocks (SIBx), reducing overhead while maintaining critical connectivity. This broadcast-centric approach ensures efficient communication and resource allocation, especially for UEs transitioning between different states or cells, highlighting the system's ability to balance network performance and UE efficiency.

[0070] Figure 5 The architecture of the user equipment (UE) (120) is illustrated, highlighting the functional components or parts that enable efficient communication and interaction with the network (110A / 110B) in various states, including connected, idle, and inactive modes. The UE may be equipped with hardware and software components designed to seamlessly manage signaling, measurement, and switching.

[0071] UE components: 1. Memory (1202): The memory can store the operational data, instructions, and configurations required for the functions of the UE. It can save the measurement configuration received from the network, enabling the UE to efficiently perform tasks such as carrier measurement and cell reselection.

[0072] Processor (1204): The processor can be responsible for executing instructions stored in memory, including processing signaling messages, managing state transitions, and performing carrier measurements. It can support decision-making for tasks including but not limited to carrier prioritization and executing mobility protocols.

[0073] Transmitter (1208): This component manages outbound communications, such as sending measurement reports and registration requests to the network.
