Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 936,240, filed on September 28, 2022, entitled “EARLY MEASUREMENT REPORTING VERIFICATION FOR NON-CONNECTED MODE USER EQUIPMENT,” which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for early measurement report validation for non-connected mode user equipment (UE). Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards; and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0028] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such a device or method practiced using other structures, functionality, or structure and functionality other than the various aspects of the disclosure set forth herein or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present claim.

[0029] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0030] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0031] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0032] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0033] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown in , network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0034] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a plurality of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeatedly perform at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions, but not another base station function. In this way, a single device may include more than one base station.

[0035] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0036] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0037] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0038] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. UE 120 may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.

[0039] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags that may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0040] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0041] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0042] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 6 GHz” band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0043] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and thus the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band.

[0044] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0045] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may perform an early measurement report (EMR) measurement for a first set of carriers in an EMR time window; perform at least one verification operation for the EMR measurement based at least in part on at least one carrier measurement in the verification time window; and send measurement results associated with the EMR measurement for one or more carriers in the first set of carriers to a network node based at least in part on the at least one verification operation. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0046] In some aspects, as described in more detail elsewhere herein, the communication manager 140 may receive configuration information indicating multiple target carriers for inter-frequency measurement; perform measurements for cell detection on reference carriers in a carrier group of the multiple target carriers in a first time window; and selectively perform inter-frequency measurement on the carrier group in a second time window based at least in part on the cell detection on the reference carriers in the carrier group. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0047] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The content described is different.

[0048] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0049] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0050] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0051] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0052] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0053] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Fig. 6A , Figure 6B , Fig. 7A , Figure 7B as well as Figures 8 to 11 ) any aspects of any of the methods described herein.

[0054] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to execute the instructions described herein (e.g., reference 20). Fig. 6A , Figure 6B , Fig. 7A , Figure 7B as well as Figures 8 to 11 ) any aspects of any of the methods described herein.

[0055] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 8 The process of 800 Fig. 9 900 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly executed, or executed after compilation, conversion, and / or interpretation), may cause one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0056] In some aspects, a UE (e.g., UE 120) includes a component for performing EMR measurements for a first set of carriers in an EMR time window; a component for performing at least one verification operation for the EMR measurements based at least in part on at least one carrier measurement in the verification time window; and / or a component for sending a measurement result associated with the EMR measurements for one or more carriers in the first set of carriers to a network node based at least in part on the at least one verification operation. The components for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0057] In some aspects, a UE (e.g., UE 120) includes means for receiving configuration information indicating multiple target carriers for inter-frequency measurement; means for performing measurements for cell detection on a reference carrier in a carrier group of the multiple target carriers in a first time window; and / or means for selectively performing inter-frequency measurement on the carrier group in a second time window based at least in part on the cell detection on the reference carrier in the carrier group. Means for the UE to perform operations described herein may include, for example, one or more of the following: communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0058] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0059] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The content described is different.

[0060] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0061] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of a CU, a DU, and a RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0062] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0063] Figure 3 3 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units, such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both. The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0064] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces, the one or more interfaces being configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0065] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0066] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers, at least in part, according to a functional split (such as a functional split defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may further host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0067] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions or low PHY layer functions based on functional split (e.g., functional split defined by 3GPP) (such as lower layer functional split), such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0068] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RTRIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0069] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or communicate with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0070] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to regulate RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0071] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The content described is different.

[0072] Figure 4 4 are diagrams illustrating examples 400 and 410 of secondary cell (SCell) settings for a UE (e.g., UE 120) when switching from a non-connected mode to a connected mode according to the present disclosure. The connected mode may be an RRC connected mode, in which an active RRC connection is established between the UE and a network node (e.g., network node 110). The non-connected mode may be an idle mode (e.g., RRC idle) or an inactive mode (e.g., RRC inactive).

[0073] Example 400 is an example of an SCell configuration for a UE where the UE does not perform non-connected mode EMR measurements. As shown in reference numeral 402, when the UE is operating in an idle or inactive mode, new traffic to be sent to or from the UE may arrive. For example, new downlink traffic to be sent from a network node to the UE may arrive at a buffer of the network node, or new uplink traffic to be sent by the UE to the network node may arrive at a buffer of the UE.

[0074] As indicated by reference numeral 404, the UE and the network node may perform a connection setup procedure to establish a connection between the UE and the network (e.g., switch the UE to a connected mode). The connection setup procedure may be an initial access procedure or a random access procedure, such as a 4-step random access channel (RACH) procedure or a 2-step RACH procedure. For example, in a 4-step RACH procedure, the UE may send a random access message (Msg1) including a PRACH preamble to the network node using a physical RACH (PRACH) resource associated with a synchronization symbol block (SSB) of the network node. The network node may send a random access response (Msg2) to the UE. The random access response (Msg2) may indicate a resource allocation to be used by the UE 120 to send an RRC connection request. The UE may send an RRC connection request (Msg3) to the network node in the resources allocated by the random access response. For example, the RRC connection request may be an RRC setup request message (e.g., when the UE is in an idle mode) or an RRC recovery request (e.g., when the UE is in an inactive mode). The network node may send an RRC connection setup message (Msg4) to the UE. For example, the RRC connection setup may be an RRC setup message or an RRC recovery message. The UE may then send a message (Msg5) to the network node indicating that the UE has successfully received the RRC connection setup message. For example, Msg5 may be an RRC setup complete message or an RRC recovery complete message. In some examples, the network node with which the UE establishes an RRC connection using the connection setup procedure may be a master node (MN) associated with a master cell group (MCG), and the UE may perform the connection setup procedure on a master cell (PCell) of the MCG.

[0075] As shown by reference numeral 406, when operating in connected mode (e.g., after establishing an RRC connection during a connection setup process), the UE may perform measurements on one or more candidate SCells. For example, the UE may perform measurements (e.g., RSRP and / or RSRQ measurements) on one or more SCells of an MCG. Additionally or alternatively, the UE may perform measurements (e.g., RSRP and / or RSRQ measurements) on cells in one or more candidate secondary cell groups (SCGs). In some examples, the UE may receive a configuration for candidate SCell measurements to be performed from a network node on a PCell, and the UE may perform measurements on the candidate SCell (and / or candidate SCG) based at least in part on the configuration. The UE may report measurements on the candidate SCell (and / or candidate SCG) to a network node (e.g., MN).

[0076] As shown in reference numeral 408, the network node and the UE may perform a carrier aggregation (CA) and / or dual connectivity (DC) setup process. CA is a technology that enables two or more component carriers (CCs, sometimes referred to as carriers) to be combined (e.g., combined into a single channel) for a single UE to enhance data capacity. In CA, the UE is configured with a PCell (also referred to as a primary carrier) and one or more SCells (also referred to as secondary carriers). The terms "carrier" and "cell" may be used interchangeably herein. In some examples, the network node may configure the SCell based at least in part on candidate SCell measurements, and the network node may activate the SCell for the UE. For example, the network node may send a MAC control element (MAC-CE) for SCell activation to the UE to activate the SCell for the UE. Once the SCell is activated, the UE may use the SCell to receive and / or send traffic. In some examples, the network node may configure and activate multiple SCells for the UE.

[0077] In DC, the UE may be configured to communicate with a MN (e.g., a first network node) on an MCG and with a secondary node (SN) (e.g., a second network node) on an SCG. In this case, the UE may be configured with a CA (e.g., an MCG and an SCG) on each cell group. That is, the MCG may include a PCell and one or more SCells, and the SCG may include a primary secondary cell (PSCell) (e.g., a primary cell of the SCG) and one or more SCells. In some examples, the MN may send the configuration of the SCG to the UE, and the UE may communicate with the SN based at least in part on the configuration of the SCG.

[0078] Example 410 is an example of an SCell setting of a UE, wherein the UE performs non-connected mode EMR measurements. As shown in reference numeral 412, when operating in non-connected mode (e.g., idle mode or inactive mode), the UE may perform EMR measurements of one or more candidate SCells. EMR measurements are measurements of one or more carriers (or cells) performed in idle mode (e.g., RRC idle) or inactive mode (e.g., RRC inactive) during the time duration when the UE switches to idle mode or inactive mode. The UE may receive an EMR measurement configuration from a network node (e.g., when operating in connected mode), the EMR measurement configuration indicating the carrier / cell on which the UE is to perform EMR measurements. For example, an EMR measurement configuration (e.g., EarlyMeasConfig) may be included in an RRC release message that triggers the UE to switch from connected mode to idle mode or inactive mode. When the UE switches to idle mode or inactive mode, the UE may perform EMR measurements according to the EMR measurement configuration during the time duration associated with the EMR timer. For example, the EMR timer may be a timer that starts after the UE receives an RRC release message that triggers the UE to switch to an idle mode or an inactive mode (eg, a T331 timer in the 3GPP standard).

[0079] The UE may be configured to perform EMR measurements of one or more inter-frequency CA / DC candidate cells (e.g., cells of one or more candidate SCells and / or one or more candidate SCGs). An inter-frequency cell (or inter-frequency carrier) is a cell / carrier to be measured that is on a frequency different from the frequency of the cell / carrier of the current serving cell for the UE (e.g., the cell / carrier on which the UE resides in idle / inactive mode). Inter-frequency measurements are measurements performed on inter-frequency cells / carriers. In some examples, the UE may have the ability to perform EMR measurements for up to a certain number of inter-frequency carriers. For example, depending on the budget for the total number of inter-frequency / inter-RAT carriers for measurements in idle or inactive mode, the UE may be configured with up to 7 NR inter-frequency carriers.

[0080] The carrier set configured for EMR measurement may include one or more carriers overlapping with the carrier set configured for mobility measurement (e.g., cell reselection measurement) in idle / inactive mode. An overlapping carrier is a carrier included in the carrier set configured for EMR measurement and the carrier set configured for mobility measurement. The carrier set configured for EMR measurement may include one or more non-overlapping carriers that are not included in the carrier set configured for mobility measurement. In some examples, there may be no distinction between overlapping carriers and non-overlapping carriers with respect to performing mobility measurements. For example, the measurement interval for EMR measurement may be the same as the measurement interval for mobility measurement in idle / inactive mode.

[0081] In some examples, the EMR measurements may include cell / carrier level measurements (e.g., cell / carrier level RSRP and / or RSRQ measurements) for each carrier and / or beam level measurements (e.g., beam level RSRP and / or RSRQ measurements) for multiple beams (e.g., associated with corresponding SSBs) for each carrier. In some examples, beam level EMR measurements may be an optional capability of the UE. The measurement time for beam level EMR measurements may be scaled similarly to beam level connected mode measurements (e.g., the scaling factor of the SSB reading time is 3 for FR1 and 5 for FR2). In some examples, the UE may perform beam level EMR measurements for up to 7 SSB indices and / or physical cell identifiers (PCIs) for FR1 and up to 10 SSB indices and / or PCIs for FR2. In some examples, the thresholds for measurement accuracy and signal-to-noise ratio (SNR) for EMR measurements may be relaxed by 1.5 dB and 2 dB, respectively, compared to connected mode measurements.

[0082] When the UE is operating in an idle or inactive mode, new traffic to be sent to or from the UE may arrive, as indicated by reference numeral 414. For example, new downlink traffic to be sent from a network node to the UE may arrive at a buffer of the network node, or new uplink traffic to be sent by the UE to the network node may arrive at a buffer of the UE.

[0083] As indicated by reference numeral 416, the UE and the network node may perform a connection setup procedure to establish a connection between the UE and the network (e.g., switching the UE to a connected mode), and the UE may report EMR measurement results for one or more candidate SCells during the connection setup procedure. The connection setup procedure may be an initial access procedure or a random access procedure, such as a 4-step RACH procedure or a 2-step RACH procedure.

[0084] In some aspects, when the UE is in an inactive mode (e.g., RRC inactive), an RRC recovery message (Msg4) sent by a network node (e.g., the last serving MN of the UE) to the UE during a RACH procedure may include a request to report EMR measurements. In this case, the UE may include an EMR indicating EMR measurements for one or more SCell candidates in an RRC recovery complete message (Msg5) sent to the network node (e.g., the last serving MN) during the RACH procedure.

[0085] In some other aspects, when the UE is in idle mode (e.g., RRC idle) or inactive mode (e.g., RRC inactive), the UE may include an indication that a measurement report is available in Msg5 (e.g., in an RRC setup complete message or an RRC recovery complete message sent to a network node) during a RACH procedure. In this case, the network node may send a UE information request including a measurement report request to the UE. The UE may then send a UE information response to the network node (e.g., MN), the UE information response including an EMR indicating EMR measurements of one or more SCell candidates. In some examples, the network node may send a UE information request to the UE after configuring the UE with security information. For example, the network node may send an RRC security mode command to the UE after receiving Msg5 (e.g., an RRC setup complete message or an RRC recovery complete message). The UE may send an RRC security mode complete message to the network node. The network node may then send a UE information request to the UE after receiving the RRC security mode complete message from the UE.

[0086] As shown in reference numeral 418, the network node and the UE may perform a CA and / or DC setup process based at least in part on EMR measurements. For example, the network node may configure the SCell based at least in part on EMR measurements of one or more candidate SCells, and the network node may activate the SCell for the UE. For example, the network node may send a MAC-CE for SCell activation to the UE to activate the SCell for the UE. Once the SCell is activated, the UE may use the SCell to receive and / or send services. In some examples, the network node may configure and activate multiple SCells for the UE based at least in part on EMR measurements of one or more candidate SCells. Additionally or alternatively, the network node (e.g., MN) may configure and / or activate an SCG for the UE based at least in part on EMR measurements. In this case, once the SCG is configured and / or activated for the UE, the UE may communicate with the SN on the SCG.

[0087] like Figure 4 As shown in example 400, in the example where EMR measurements are not reported, the amount of time between the UE switching to connected mode and completing the CA / DC setup may exceed 500ms. Figure 4As shown in example 410 of , in the example of reporting EMR measurements, the amount of time between the UE switching to connected mode and completing CA / DC establishment can be less than 100 ms. Therefore, using EMR measurements in the CA / DC setup process reduces the latency associated with the CA / DC setup process when the UE switches to connected mode, compared to a CA / DC setup process without EMR measurements. For example, using EMR measurements in the CA / DC setup process reduces the amount of time used for configuration and activation of the SCell when the UE switches from idle / inactive mode to connected mode.

[0088] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The content described is different.

[0089] FIG. 5A to FIG. 5B is a diagram illustrating an example 500 of a non-connected mode UE configured with an inter-frequency layer for cell reselection and EMR measurement according to the present disclosure.

[0090] like Figure 5A As shown, example 500 includes a deployment scenario (shown by reference numeral 502) in which an RRC idle mode or RRC inactive mode UE (e.g., UE 120) is configured with an inter-frequency layer for cell reselection and EMR measurement. As shown by reference numeral 502, the deployment scenario may include a wireless network having multiple serving cells deployed in multiple frequency layers (f0, f1, f2, f2, f4, and f5). As shown by reference numeral 504, Figure 5A An exploded view of the frequency layers relative to the deployment scenario is shown. Figure 5A As shown, frequency layer f0 may be the frequency layer where idle / inactive mode UE resides, and the UE may perform intra-frequency cell reselection measurements (eg, intra-frequency mobility measurements) for carriers / cells in f0. Figure 5A As further shown, frequency layers f1, f2, f3, f4, and f5 may be inter-frequency layers (e.g., frequency layers other than frequency layer f0 on which the UE resides). Frequency layers f2, f3, and f5 may be frequency layers configured for EMR measurements (e.g., frequency layers of a carrier configured for EMR measurements), and may be referred to as "EMR frequency layers". In some aspects, the EMR frequency layers (f2, f3, and f5) may be frequency layers for a carrier for which the CA may be configured with a current serving cell on which the UE resides. That is, the EMR frequency layers (f2, f3, and f5) may be frequency layers for a candidate SCell for the UE.

[0091] Frequency layers f1, f2, f3, and f4 may be configured for cell reselection measurements (e.g., mobility measurements) and may be configured with priorities for cell reselection. Frequency layer f1 may be configured with a lower cell reselection priority than frequency layer f0, frequency layer f2 may be configured with a cell reselection priority equal to frequency layer f0, and frequency layers f3 and f4 may be configured with a higher cell reselection priority than frequency layer f0. Frequency layer f5 may be a non-measurement mobility frequency layer (e.g., a frequency layer not configured for mobility / cell reselection measurements).

[0092] In some examples, when in idle / inactive mode, the frequency layer on which the UE performs inter-frequency cell reselection measurements (e.g., mobility measurements) can be based at least in part on a determination of whether UE mobility criteria are met. For example, when the serving cell signal power level (S rxlev ) (e.g., RSRP measurement on the serving cell) is less than or equal to a power threshold (e.g., S nonintraSearchP ) and / or serving cell signal quality (S qual ) (e.g., RSRQ measurement on the serving cell) is less than or equal to a quality threshold (e.g., S nonintraSearchQ ), the UE mobility criteria can be met. Figure 5A As shown, the first UE (UE1) may not meet the UE mobility criteria (e.g., S rxlev >S nonintraSearchP And S qual >S nonintraSearchQ ) and the second UE (UE2) may satisfy the UE mobility criteria (e.g., S rxlev ≤S nonintraSearchP And S qual ≤S nonintraSearchQ ). In some examples, a UE that meets the UE mobility criteria (e.g., UE2) may perform inter-frequency cell reselection measurements in frequency layers configured with all cell reselection priorities (e.g., f1, f2, f3, and f4) when operating in an idle / inactive state. In some examples, a UE that does not meet the UE mobility criteria (e.g., UE1) may perform inter-frequency cell reselection measurements only in frequency layers configured with cell reselection priorities higher than the current serving cell (e.g., f3 and f4) when operating in an idle / inactive state.

[0093] Figure 5B Shown in Figure 5A Inter-frequency measurements are performed by an idle / inactive mode UE in the deployment scenario shown. Figure 5BAs shown, an idle / inactive mode UE can perform EMR measurements only when an EMR timer (e.g., T331 timer) is running, and an idle / inactive mode UE can perform cell / carrier reselection measurements when an EMR timer (e.g., T331 timer) is running and after the EMR timer (e.g., T331 timer) has expired.

[0094] As shown by reference numeral 506, Figure 5B It shows that when the UE does not meet the UE mobility criteria (e.g., S rxlev >S nonintraSearchP And S qual >S nonintraSearchQ ). In this case, cell / carrier reselection measurements are performed only for carriers in frequency layers f3 and f4 (e.g., frequency layers with higher cell reselection priorities than frequency layer f0 on which the UE resides). As indicated by reference numeral 506a, the UE does not perform any measurements in frequency layer f1, which is not configured for EMR and is configured with a lower cell reselection priority than the serving cell. As indicated by reference numeral 506b, while the EMR timer is running, the UE performs measurements for EMR for carriers in frequency layer f2 (e.g., carriers that do not overlap with the set of carriers for which cell / carrier reselection measurements are performed), and after the EMR timer has expired, the UE does not perform measurements for carriers in frequency layer f2. As shown in reference numeral 506c, when the EMR timer is running, the UE performs measurements for EMR and carrier / cell reselection for carriers in frequency layer f3 (e.g., overlapping carriers configured for EMR and cell reselection measurements), and after the EMR timer has expired, the UE continues to perform measurements for carrier / cell reselection for carriers in frequency layer f3. As shown in reference numeral 506d, when the EMR timer is running and after the EMR timer has expired, the UE performs measurements for carrier / cell reselection for carriers in frequency layer f4. As shown in reference numeral 506e, when the EMR timer is running, the UE performs measurements for EMR for carriers in frequency layer f5 (e.g., non-overlapping carriers), and after the EMR timer has expired, the UE does not perform measurements for carriers in frequency layer f5.

[0095] As shown by reference numeral 508, Figure 5B It is shown that for a UE that satisfies the UE mobility criteria (e.g., S rxlev ≤S nonintraSearchP And S qual ≤S nonintraSearchQ). In this case, cell / carrier reselection measurements are performed only on detected carriers / cells in all frequency layers (e.g., f1, f2, f3, and f4) for which cell reselection / mobility measurements are configured. As shown by reference numerals 508a and 508d, when the EMR timer is running and after the EMR timer expires, the UE performs measurements for carrier / cell reselection for carriers in frequency layers f1 and f4. As shown by reference numerals 508b and 508c, when the EMR timer is running, the UE performs measurements for EMR and carrier / cell reselection for carriers in frequency layers f2 and f3 (e.g., overlapping carriers configured for EMR and cell reselection measurements), and after the EMR timer has expired, the UE continues to perform measurements for carrier / cell reselection for carriers in frequency layers f2 and f3. As indicated by reference numeral 508e, the UE performs measurement for EMR for carriers (eg, non-overlapping carriers) in frequency layer f5 while the EMR timer is running, and does not perform measurement for carriers in frequency layer f5 after the EMR timer has expired.

[0096] As indicated above, FIG. 5A to FIG. 5B Other examples can be found in the FIG. 5A to FIG. 5B The content described is different.

[0097] In some examples, UE guidelines for UE receive (Rx) beam scanning (e.g., in wireless communication standards such as 3GPP standards) and related UE environments can be based at least in part on the assumption that the UE can receive in one Rx direction at a time. For example, Technical Specification (TS) 38.133 of the 3GPP standard (e.g., TS 38.133, Table 4.2.2.4-1) specifies guidelines for FR2 inter-frequency measurement delay for UEs in RRC idle mode. According to the guidelines for FR2 inter-frequency measurement delay specified in TS 38.133, even when only the delay associated with detecting inter-frequency carriers (T detect,NR_Inter ) and the delay associated with performing the inter-frequency measurement (T measure,NR_Inter), the FR2 measurement delay for idle mode EMR measurements may also be significant. For example, even when only one inter-frequency carrier is measured, in the case of a discontinuous reception (DRX) cycle of 320 ms, the total delay based on the guidelines (e.g., in the case of a scaling factor (N1) of 8) will be equal to DRX cycle*(36*N1*1.5)+(4*N1*1.5)=320*40*8*1.5=153600 ms=153.6 s (approximately 2.5 minutes). Therefore, the FR2 measurement delay for idle / inactive mode inter-frequency measurements (such as EMR measurements) may be very large, and as the number of carriers increases, the FR2 measurement delay scales linearly with the number of carriers. This may result in a large measurement cycle for performing inter-frequency measurements for each carrier, which may result in increased power consumption and reduced battery life for the UE when the UE is in idle or inactive mode.

[0098] Furthermore, in some cases, due at least in part to the nature of FR2 (e.g., beam-based communications for both network nodes and UEs and limited and non-uniform spatial coverage), depending on the time interval between EMR measurements performed by the UE in idle or inactive mode and reporting the EMR measurements when the UE switches to connected mode, the EMR measurement results may be outdated. This may cause measurements of candidate carriers for CA and / or DC (e.g., for candidate SCells) to be inaccurate when reported, which may result in a suboptimal SCell (or SCG) being activated for the UE when the UE establishes an RRC connection with the network node. As a result, the UE may experience unreliable service delivery on the suboptimal SCell (or SCG) and / or delays associated with activating the correct SCell (or SCG) for the UE.

[0099] Some techniques and apparatus described herein enable EMR measurement report verification for non-connected mode UEs. The UE may perform EMR measurements for a first set of carriers in an EMR time window. The UE may perform at least one verification operation for the EMR measurement based at least in part on at least one carrier measurement in the verification time window. The UE may send measurement results associated with the EMR measurement for one or more carriers in the first set of carriers to a network node based at least in part on the at least one verification operation. Thus, the likelihood that the reported EMR measurement results are still accurate when the UE switches to connected mode is increased, which reduces the latency associated with configuring and activating an SCell (or SCG) when the UE switches to connected mode, and increases the reliability of services delivered via the activated SCell (or SCG).

[0100] Some techniques and apparatus described herein enable grouping of carriers for fast inter-frequency measurements. In some aspects, a UE may receive configuration information indicating multiple target carriers for inter-frequency measurements. The UE may perform measurements for cell detection on a reference carrier in a carrier group of multiple target carriers in a first time window. The UE may selectively perform inter-frequency measurements on the carrier group in a second time window based at least in part on the cell detection on the reference carrier in the carrier group. Thus, the total delay for performing inter-frequency measurements for a carrier group is reduced at least by reducing the delay associated with performing cell detection individually for each carrier in the carrier group. This can reduce the size of a measurement cycle for performing inter-frequency measurements for a carrier group, which can reduce power consumption and save battery life of the UE.

[0101] FIG. 6A to FIG. 6B 6 is a diagram illustrating an example 600 associated with early measurement report validation for non-connected mode UEs according to the present disclosure. Fig. 6A As shown, example 600 includes communications between a network node 110 and a UE 120. In some aspects, the network node 110 and the UE 120 may be included in a wireless network, such as the wireless network 100. The network node 110 and the UE 120 may communicate via a wireless access link, which may include an uplink and a downlink.

[0102] like Fig. 6A And as shown by reference numeral 605, the network node 110 may send an RRC release message including an EMR configuration, and the UE 120 may receive the RRC release message. The RRC release message may indicate to the UE 120 that the UE 120 is to switch to an idle mode (e.g., RRC idle) or an inactive mode (e.g., RRC inactive). The RRC release message may include an EMR configuration (e.g., EarlyMeasConfig), which indicates a configuration for EMR measurements to be performed by the UE 120 when operating in an idle or inactive state and a configuration for reporting EMR measurements. The EMR configuration may include a cell list (or carrier list) indicating a first carrier set for which EMR measurements are configured. The first carrier set may also be referred to herein as an EMR carrier. In some aspects, an EMR carrier (e.g., a carrier included in the first carrier set) may be a candidate carrier for CA and / or DC. For example, the EMR carrier may be a candidate SCell for the UE 120.

[0103] In some aspects, the EMR configuration may indicate at least one verification parameter associated with at least one verification operation to be performed for the EMR measurement. For example, the EMR configuration may indicate a first threshold (X) for a first verification operation (e.g., a first RSRP threshold and / or a first RSRQ threshold) and / or a second threshold (Y) for a second verification operation (e.g., a second RSRP threshold and / or a second RSRQ threshold). Additionally or alternatively, the EMR configuration may indicate a reference carrier for the first verification operation. In some aspects, a reference cell on the reference carrier may be further included in the configuration for the verification operation.

[0104] In some aspects, the RRC release message (or another configuration message received by UE 120) may indicate a configuration for cell reselection measurements performed by UE 120 when UE 120 is in an idle or inactive mode. For example, the configuration for cell reselection measurements may configure UE 120 to determine a second set of carriers (e.g., cell reselection carriers) for cell reselection measurements. For example, the configuration may identify carriers and / or frequencies (e.g., frequency layers) configured for cell reselection measurements, and the configuration may indicate respective cell reselection priorities associated with the frequencies (or carriers) configured for cell reselection measurements. The configuration for cell reselection measurements may also indicate a power threshold (e.g., S R) used to determine whether UE mobility criteria of UE 120 are met. nonintraSearchP ) and / or quality thresholds (e.g., S nonintraSearchQ ).

[0105] like Fig. 6A As further shown by reference numeral 610, UE 120 may switch to an idle mode (e.g., RRC idle) or an inactive mode (e.g., RRC inactive). UE 120 may switch to the idle mode or inactive mode in conjunction with receiving an RRC release message. For example, the RRC release message may trigger UE 120 to switch to the idle mode or inactive mode.

[0106] like Fig. 6AAnd as further shown by reference numeral 615, UE 120 may perform EMR measurements for a first set of carriers (e.g., EMR carriers) in an EMR time window. When UE 120 is operating in an idle mode or an inactive mode, UE 120 may perform EMR measurements for EMR carriers. UE 120 may perform EMR measurements for EMR carriers within a time duration associated with an EMR timer. The EMR timer may be started when UE 120 receives an RRC release message and runs for a time duration associated with the EMR timer. For example, the EMR timer may be a T331 timer. In this case, the EMR timer may be configured (e.g., in an EMR configuration) with a time duration of 10, 30, 60, 120, 180, 240, or 300 seconds. In some aspects, UE 120 may periodically repeat EMR measurements for EMR carriers during a time duration associated with the EMR timer according to a measurement cycle configured for EMR measurements. In some aspects, UE 120 may perform EMR measurements on the EMR carrier in an EMR time window (WO) within a time duration associated with the EMR timer. The EMR time window WO may be a time window that begins a certain amount of time before the EMR timer expires and ends when the EMR timer expires. In some aspects, the EMR time window WO may be the same as the time duration associated with the EMR timer. In some other aspects (e.g., Figure 6B ), the EMR time window W0 may be different from (eg, shorter than) the time duration associated with the EMR timer.

[0107] The EMR measurements for each carrier in the first set of carriers (e.g., for each EMR carrier) may include RSRP and / or RSRQ measurements performed on the carrier. In some aspects, the RSRP and / or RSRQ measurements for the carrier may include cell / carrier level RSRP and / or RSRP measurements and / or beam level RSRP and / or RSRQ measurements. For example, the UE 120 may perform beam level RSRP and / or RSRQ measurements for one or more SSBs (e.g., each SSB corresponding to a transmit (Tx) beam of a corresponding network node). Additionally or alternatively, the UE 120 may perform beam level RSRP and / or RSRQ measurements for one or more UE Rx beams per SSB.

[0108] In some aspects, when UE 120 is in idle mode or inactive mode, UE 120 may also perform cell reselection measurements for a second set of carriers. For example, the cell reselection measurements may include RSRP and / or RSRQ measurements for the second set of carriers. The second set of carriers for which the UE performs cell reselection measurements may be based at least in part on a determination of whether UE mobility criteria are met. For example, when Srxlev ≤S nonintraSearchP and / or S qual ≤S nonintraSearchQ When the UE mobility criteria (e.g., S rxlev ≤S nonintraSearchP and / or S qual ≤S nonintraSearchQ ), when operating in an idle / inactive state, UE 120 may perform inter-frequency cell reselection measurements for carriers detected in all frequency layers configured for cell reselection (e.g., utilizing all cell reselection priorities). rxlev >S nonintraSearchP and / or S qual >S nonintraSearchQ ), when operating in an idle / inactive state, UE 120 may perform inter-frequency cell reselection measurements only for carriers detected in a frequency layer configured with a higher cell reselection priority than the current serving cell. UE 120 may always perform intra-frequency cell reselection measurements on carriers in the same frequency layer as the current serving cell.

[0109] Figure 6B 1 shows that when the mobility criteria (e.g., S rxlev >S nonintraSearchP and / or S qual >S nonintraSearchQ ) is an example of EMR and cell reselection measurements in the case of Figure 6B As shown, frequency layers f2, f3, and f4 may be frequency layers for EMR. In this case, the first carrier set (e.g., EMR carriers) includes carriers deployed in frequency layers f2, f3, and f4. Frequency layers f0, f1, f2, and f3 may be frequency layers for cell reselection. Frequency layer f0 may be the frequency layer of the current serving cell on which UE 120 resides when in idle mode or inactive mode. Frequency layer f1 may be configured with a lower cell reselection priority than frequency layer f0. Frequency layer f2 may be configured with a cell reselection priority to frequency layer f0. Frequency layer f3 may be configured with a higher cell reselection priority than frequency layer f0. As shown Figure 6B As shown, when the mobility criteria (e.g., S rxlev >S nonintraSearchP and / or S qual >S nonintraSearchQ), the second carrier set for which the cell reselection measurement is performed by the UE 120 may include carriers in frequency layers f0 and f3. In this case, the carriers in frequency layer f3 may be overlapping carriers included in the first carrier set for which the EMR measurement is performed (e.g., in frequency layers f2, f3, and f4) and the second carrier set for which the cell reselection measurement is performed (e.g., carriers in f0 and f3).

[0110] like Figure 6B As shown, UE 120 may include a measurement component 642 for EMR and a measurement component 644 for non-EMR. When UE 120 is in an idle mode or an inactive mode, the measurement component 642 for EMR may perform EMR measurements for carriers in a first set of carriers. When UE 120 is in an idle mode or an inactive mode, the measurement component 644 for non-EMR may perform cell reselection measurements for a second set of carriers. In some aspects, the measurement component 642 for EMR and the measurement component 644 for non-EMR may be included in Fig.10 In the measurement component 1008 depicted in FIG.

[0111] As shown by reference numeral 646, UE 120 (e.g., using measurement component 642 for EMR) may perform EMR measurements (e.g., inter-frequency EMR measurements) for carriers in frequency layer f4 (or multiple carriers in frequency layer f4) during a time duration associated with an EMR timer. The EMR measurements for carriers in frequency layer f4 may include one or more EMR measurements in EMR time window W0. UE 120 may stop performing EMR measurements for carriers (or multiple carriers) in frequency layer f4 at the end of the time duration associated with the EMR timer.

[0112] As shown by reference numeral 648, UE 120 (e.g., using measurement component 642 for EMR) may perform measurements (e.g., inter-frequency measurements) for EMR and cell reselection for a carrier (or multiple carriers in frequency layer f3) in a time duration associated with an EMR timer. For example, measurement component 642 for EMR may perform EMR measurements for a carrier (or multiple carriers) in frequency layer f3, and the EMR measurements may also be used for cell reselection measurements. In this case, measurement component 644 for non-EMR may not perform cell reselection measurements for a carrier (or multiple carriers) in frequency layer f3 during the time duration associated with the EMR timer, because the measurements performed by the measurement component for EMR may be used as EMR measurements and cell reselection measurements for a carrier (or multiple carriers) in frequency layer f3. Measurements for EMR and cell reselection for a carrier (or multiple carriers) in frequency layer f3 may include one or more EMR measurements in EMR time window W0. The measurement component 642 for EMR can stop performing EMR measurements for the carrier (or multiple carriers) in frequency layer f3 at the end of the time duration associated with the EMR timer. As shown by reference numeral 650, the UE 120 (e.g., using the measurement component 644 for non-EMR) can continue to perform cell reselection measurements for the carrier (or multiple carriers) in frequency layer f3 after the end of the time duration associated with the EMR timer.

[0113] As shown by reference numeral 652, UE 120 (e.g., using measurement component 642 for EMR) may perform EMR measurements (e.g., inter-frequency EMR measurements) for carriers in frequency layer f2 (or multiple carriers in frequency layer f2) during a time duration associated with an EMR timer. The EMR measurements for carriers in frequency layer f2 may include one or more EMR measurements in EMR time window W0. UE 120 may stop EMR measurements for carriers (or multiple carriers) in frequency layer f2 at the end of the time duration associated with the EMR timer. As shown by reference numeral 654, in the case where mobility criteria (e.g., S rxlev >S nonintraSearchP and / or S qual >S nonintraSearchQ ), the UE 120 (e.g., the measurement component 644 for non-EMR) may not perform cell reselection measurements for a carrier (or multiple carriers) in frequency layer f2 (e.g., which is configured with a cell reselection priority equal to that of frequency layer f0).

[0114] As shown by reference numeral 656, when the mobility criteria (e.g., S rxlev >S nonintraSearchPand / or S qual >S nonintraSearchQ ), the UE 120 (e.g., the measurement component 644 for non-EMR) may not perform measurements on a carrier (or multiple carriers) in the frequency layer f1 (e.g., which is configured with a cell reselection priority lower than the frequency layer f0). As shown by reference numeral 658, the UE 120 (e.g., using the measurement component 644 for non-EMR) may perform intra-frequency cell reselection measurements on carriers (e.g., intra-frequency carriers) in the frequency layer f0 (or for multiple intra-frequency carriers in the frequency layer f0) during and after the time duration associated with the EMR timer. In some aspects, the intra-frequency cell reselection measurements performed on the intra-frequency carriers in the frequency layer f0 may include one or more intra-frequency cell reselection measurements in the EMR time window W0.

[0115] As shown by reference numeral 660, the UE 120 may save per-carrier measurement results for each of the EMR carriers (e.g., for each of the carriers in frequency layers f2, f3, and f4) in a memory of the UE 120 at the end of a timer duration associated with the EMR timer (e.g., when the EMR timer expires). In some aspects, the measurement results for the EMR measurement may include a measurement result set that indicates, for each carrier, RSRP and / or RSRQ values ​​measured for different SSB identifiers (SSB-IDs) and different Rx beam identifiers (Rx-beam-IDs). For example, the measurement result set for the EMR measurement may indicate a value of (RSRP / Q, SSB-ID, Rx-beam-ID) per EMR carrier / cell.

[0116] As indicated by reference numeral 662, the UE 120 may save, in a memory of the UE 120, a measurement result of at least one reference carrier in a second set of carriers (e.g., carriers in frequency layers f0 and f3) for which cell reselection measurements are performed at the end of a timer duration associated with the EMR timer. For example, the at least one reference carrier may include at least one of an overlapping inter-frequency carrier (e.g., a carrier in frequency layer f3) or an intra-frequency carrier (e.g., a carrier in frequency layer f0) included in the first set of carriers and the second set of carriers. In some aspects, the UE 120 may save a measurement result for a set of reference carriers included in a second set of carriers. For example, the reference carrier or set of reference carriers for which the measurement result is to be saved may be explicitly indicated by the network node 110 (e.g., in an EMR configuration or other configuration information) or implicitly selected by the UE 120 at least in part based on a rule (e.g., a rule for selecting one or more intra-frequency and / or overlapping frequency carriers). In some aspects, the UE 120 may save, in a memory of the UE 120, measurement results for all intra-frequency carriers and / or overlapping carriers. In some aspects, the reference carrier (or multiple reference carriers) may be a carrier (or multiple carriers) for which at least one measurement (e.g., a measurement for cell reselection) is performed within the EMR time window W0, and the measurement saved for the reference carrier (or multiple reference carriers) may be a measurement performed within the EMR time window (e.g., the most recent measurement performed within the EMR time window). In some aspects, the measurement results for cell reselection measurements may include a value of (RSRP / Q, SSB-ID, Rx-beam-ID) per carrier / cell for each of the one or more reference cells for which the measurement results are saved.

[0117] return Fig. 6A , as indicated by reference numeral 620, UE 120 may perform at least one verification operation for EMR measurement based at least in part on at least one carrier measurement in the verification time window. The at least one verification operation may include a first verification operation and / or a second verification operation.

[0118] As indicated by reference numeral 625, in some aspects, the UE 120 may perform a first verification operation for the EMR measurement. The first verification operation may be based at least in part on a comparison between a first measurement (e.g., a first RSRP or RSRQ measurement) for a reference carrier in the second carrier set in the EMR time window W0 and a second measurement (e.g., a second RSRP or RSRQ measurement) for the reference carrier in the first verification time window (W1). The reference carrier may be any carrier (e.g., any carrier in the second carrier set) for which a cell reselection measurement is performed by the UE 120 in idle mode or inactive mode. In some aspects, the reference carrier may be an overlapping carrier included in the first carrier set (e.g., the EMR carrier) and the second carrier set. In some aspects, the reference carrier may be an intra-frequency carrier (e.g., in the same frequency layer as the serving cell on which the UE 120 resides) for which the intra-frequency cell reselection measurement is performed by the UE 120 in idle mode or inactive mode. For example, the reference carrier / cell may be an overlapping carrier / cell or an intra-frequency carrier / cell, since such a UE 120 will have continued to measure such frequency / cell after the EMR timer expires. In some aspects, the specific frequency / carrier / cell used for the measurement of the reference carrier in W1 may be based on an explicit configuration (e.g., in the EMR configuration information) or may be selected autonomously by the UE 120. The first measurement for the reference carrier in the EMR time window W0 may be a cell reselection measurement or a measurement for cell reselection and EMR (e.g., in the projection of an overlapping carrier). The second measurement for the reference carrier may be the most recent cell reselection measurement in the first verification time window W1 (e.g., an intra-frequency cell reselection measurement or an inter-frequency cell reselection measurement).

[0119] In some aspects, in a first verification operation, UE 120 may determine whether a difference between a first RSRP or RSRQ measurement for a reference carrier in an EMR time window W0 and a second RSRP or RSRQ measurement for a reference carrier in a first verification time window W1 satisfies (e.g., is less than) a threshold. For example, UE 120 may determine whether abs[(most recent RSRP and / or RSRQ in W1)–(value saved in W0)]≥[X]dB, where X is a threshold. In some aspects, the value of threshold X may be configured by network node 110 (e.g., in an EMR configuration). The first verification time window may be a time window of a specific length starting at a specific amount of time before an RRC connection procedure for UE 120.

[0120] like Figure 6BAs shown, the reference carrier used for the first verification can be a carrier in frequency layer f3 (e.g., a carrier overlapping with the EMR carrier set) or a carrier in frequency layer f0 (e.g., an intra-frequency carrier). UE 120 (e.g., using measurement component 644 for non-EMR) can perform cell reselection measurements on a carrier (or multiple carriers) in frequency layer f3 and a carrier (or multiple carriers) in frequency layer f0 in a first verification time window. As shown by reference numeral 664, UE 120 can perform a first verification operation based at least in part on a cell reselection measurement for a reference carrier (e.g., an overlapping carrier in frequency layer f3 or an intra-frequency carrier in frequency layer f0). For example, UE 120 can compare the RSRP or RSRQ measurement for the reference carrier in W1 with the saved RSRP or RSRQ measurement for the reference carrier in W0 to determine whether the difference between the RSRP or RSRQ measurement in W1 and the saved RSRP or RSRQ measurement meets a threshold.

[0121] In some aspects, UE 120 may determine whether to send measurement results for EMR measurement of the first set of carriers to network node 110 based at least in part on the verification results of the first verification operation (e.g., during or after the RRC connection process). In some aspects, UE 120 may determine not to send measurement results for EMR measurement in conjunction with a determination that a difference between a first RSRP measurement or RSRQ measurement for a reference carrier in EMR time window W0 and a second RSRP measurement or RSRQ measurement for a reference carrier in the first verification time window W1 does not satisfy a threshold (e.g., abs[(most recent RSRP and / or RSRQ in W1)–(value stored in W0)]≥[X] dB). In some aspects, at least one verification operation performed by UE 120 may include only the first verification operation (e.g., without the second verification operation). In this case, UE 120 may determine to send measurement results for EMR measurement in conjunction with a determination that a difference between a first RSRP measurement or RSRQ measurement for the reference carrier in the EMR time window W0 and a second RSRP measurement or RSRQ measurement for the reference carrier in the first verification time window W1 satisfies a threshold (e.g., abs[(most recent RSRP and / or RSRQ in W1) – (value saved in W0)] < [X] dB).

[0122] In some aspects (e.g., Figure 6B), the at least one verification operation performed by UE 120 may include a first verification operation and a second verification operation. For example, UE 120 may perform a two-stage verification, in which UE 120 performs a first verification operation and then proceeds to a second verification operation in conjunction with a determination that the first verification operation passes. In this case, UE 120 may determine to proceed to a second verification operation in conjunction with a determination that a difference between a first RSRP measurement or RSRQ measurement for a reference carrier in EMR time window W0 and a second RSRP measurement or RSRQ measurement for a reference carrier in a first verification time window W1 satisfies a threshold value (e.g., abs[(most recent RSRP and / or RSRQ in W1)–(value saved in W0)]<[X] dB).

[0123] return Fig. 6A , as shown by reference numeral 630, UE 120 may perform a second verification operation for the EMR measurement. In some aspects, UE 120 may perform the second verification operation based at least in part on the verification result of the first verification operation. For example, UE 120 may perform the second verification operation in conjunction with a determination that the difference between a first RSRP measurement or RSRQ measurement for a reference carrier in EMR time window W0 and a second RSRP measurement or RSRQ measurement for a reference carrier in a first verification time window W1 satisfies a first threshold (e.g., abs[(most recent RSRP and / or RSRQ in W1)–(value saved in W0)]<[X]dB). In some aspects, at least one verification operation performed by UE 120 may include only the second verification operation (e.g., without the first verification operation).

[0124] The second verification operation may be based at least in part on RSRP or RSRQ measurements for at least a subset of carriers in the first set of carriers in a second verification time window (W2). Figure 6B As shown, in the case where UE 120 performs the first verification operation and the second verification operation, the first verification time window W1 is the first part of the total EMR verification time window, and the second verification time window W2 is the second part of the total EMR verification window. For example, in this case, the EMR verification window can be equal to W1+W2. In some aspects, the second verification time window W2 can be a time window of a certain duration that starts at or after the end of the first verification time window W1. Figure 6B As shown, the second verification time window may overlap in the time domain with at least a portion of an RRC connection process in which UE 120 establishes an RRC connection with a network node (eg, network node 110) and switches to an RRC connected mode.

[0125] In some aspects, in the second verification operation, the UE 120 may perform per-carrier verification for each carrier in at least a subset of carriers in the first carrier set based at least in part on a comparison of the highest RSRP or RSRQ measurement for a carrier using a certain number (M) of Rx beams in the second verification time window W1 with the RSRP or RSRQ measurement for the carrier in the EMR window. In this case, the UE 120 may determine, for each one or more carriers in the first carrier set, whether the difference between the highest RSRP or RSRQ measurement for a carrier using M Rx beams in the second verification time window W1 and the RSRP or RSRQ measurement for the carrier in the EMR window satisfies (e.g., is less than) a second threshold (Y). For example, the UE 120 may determine per carrier for one or more EMR carriers in the EMR carriers whether abs[(the highest RSRP and / or RSRQ among the M Rx beams in W2)−(the saved RSRP and / or RSRQ for the same carrier in W0)]≥YdB. In some aspects, the value of M and the selection of M Rx beams by UE 120 may depend on the specific implementation of the UE and may be based at least in part on the SSB periodicity of the cell. In some aspects, UE 120 may perform per-carrier verification for each EMR carrier (e.g., each carrier in the first carrier set). In some aspects, UE 120 may perform per-carrier verification for a subset of EMR carriers (e.g., a subset of carriers in the first carrier set) selected based at least in part on previous measurement results of EMR measurements performed for EMR carriers in WO. For example, the subset of EMR carriers may include one or more EMR carriers (e.g., one or more carriers in the first carrier set), for which the RSRP or RSRQ measurement for the carrier in WO satisfies a threshold (Z) (e.g., RSRP / Q>ZdB). In some aspects, UE 120 may determine, for each of the best N SSB-IDs of the carrier (e.g., having the highest measured RSRP or RSRQ value in WO), whether the difference between the highest RSRP or RSRQ measurement for the carrier in the M Rx beams in the verification time window and the RSRP or RSRQ measurement for the carrier in the EMR window satisfies a second threshold (Y). In some aspects, depending on the network configuration, the RSRP and / or RSRQ measurements may be cell-level measurements (e.g., measurements derived from beam-specific measurements reported to Layer 3 after beam combining / selection or measurements after Layer 3 filtering for cell quality) or network node Tx beam-level measurements (e.g., beam-specific measurements reported to Layer 3 by Layer 1 after Layer 1 filtering or beam-specific measurements after Layer 3 beam filtering).

[0126] In some aspects, the UE 120 may determine not to transmit the corresponding measurement results for EMR measurements for each of one or more EMR carriers in the EMR carrier based at least in part on the determination that the difference between the highest RSRP or RSRQ measurement for the carrier using M Rx beams in the second verification time window (W2) and the RSRP or RSRQ measurement for the carrier in the EMR window meets a second threshold (Y) (e.g., abs[(highest RSRP and / or RSRQ among [M] Rx beams in W2) – (stored RSRP and / or RSRQ for the same carrier in W0)] < Y dB). In some aspects, the UE 120 may determine to transmit the corresponding measurement results for EMR measurements for each of one or more EMR carriers in the EMR carrier based at least in part on the determination that the difference between the highest RSRP or RSRQ measurement for the carrier using M Rx beams in the second verification time window W2 and the RSRP or RSRQ measurement for the carrier in the EMR window does not meet the second threshold Y (e.g., abs[(highest RSRP and / or RSRQ among M Rx beams in W2) – (stored RSRP and / or RSRQ for the same carrier in W0)] ≥ Y dB).

[0127] As Figure 6B shown by reference numeral 666 in, the UE 120 may perform a second verification operation based at least in part on RSRP and / or RSRQ measurements (e.g., performed using the measurement component 642 for EMR) for one or more EMR carriers in the EMR carrier in the second time verification window W2. For example, the UE 120 (e.g., using the measurement component 642 for EMR) may perform an RSRP measurement for each carrier using M Rx beams for all EMR carriers or a subset of EMR carriers. Then, the UE 120 may determine for each carrier of all EMR carriers or a subset of EMR carriers whether abs[(highest RSRP and / or RSRQ among M Rx beams in W2) – (stored RSRP and / or RSRQ for the same carrier in W0)] ≥ Y dB.

[0128] Return Fig. 6A, as shown by reference numeral 635, the UE 120 may establish an RRC connection with the network node 110. The UE 120 may establish an RRC connection with the network node 110 via a random access procedure (e.g., a 4-step RACH procedure). In some aspects, the UE 120 may perform a first verification operation and / or a second verification during the RACH procedure to establish an RRC connection with the network node 110. For example, the UE 120 may initiate a RACH procedure (e.g., by sending Msg1 to the network node 110) before performing the first verification operation and / or the second verification operation. The UE 120 may switch to a connected mode (e.g., an RRC connection) at least in part based on establishing an RRC connection with the network node 110.

[0129] As shown by reference numeral 640, in some aspects, the UE 120 may send measurement results associated with EMR measurements for an EMR carrier to the network node 110 at least in part based on at least one verification operation (e.g., the first verification operation and / or the second verification operation). In some aspects, the UE 120 may selectively send measurement results associated with an EMR carrier to the network node 110 at least in part based on at least one verification operation.

[0130] In some aspects, the UE 120 may send measurement results associated with EMR measurements to the network node 110 at least in part based on determining that the difference between a first RSRP measurement or RSRQ measurement for a reference carrier in an EMR time window W0 and a second RSRP measurement or RSRQ measurement for the reference carrier in a first verification time window W1 satisfies a first threshold (e.g., abs[(nearest RSRP and / or RSRQ in W1) – (stored value in W0)] < X dB). In some aspects, the UE 120 may send measurement results associated with EMR measurements to the network node 110 at least in part based on a determination in the second verification operation. In some aspects, the UE 120 may send corresponding measurement results associated with EMR measurements for each of one or more EMR carriers in an EMR carrier at least in part based on determining that the difference between the highest RSRP or RSRQ measurement for a carrier using M Rx beams in a second verification time window W2 and the RSRP or RSRQ measurement for the carrier in an EMR window W0 satisfies a second threshold Y (e.g., abs[(highest RSRP and / or RSRQ among the M Rx beams in W2) – (stored RSRP and / or RSRQ for the same carrier in W0)] < Y dB). In this case, the UE 120 may report the most recent measurement results for the EMR carrier in W2, or report the stored EMR measurement results in W0.

[0131] In some aspects, UE 120 may select to send measurement results associated with EMR measurements based at least in part on a first verification result of the first verification operation and / or a second verification result of the second verification operation. In this case, the first verification result may correspond to the EMR measurements being verified by the first verification operation (e.g., by the first verification operation), and the second verification result may correspond to the EMR measurements being verified by the second verification operation (e.g., by the second verification operation). In some aspects, in the case where UE 120 selects to send measurement results associated with EMR measurements, UE 129 may send the measurement results to network node 110 during or after a RACH procedure to establish an RRC connection between UE 120 and network node 110. For example, in the case where UE 120 switches from an inactive mode to a connected mode, UE 120 may receive a request for a measurement report from network node 110 in an RRC resume message (e.g., Msg4) in a RACH procedure, and UE 120 may send the measurement results associated with EMR measurements in one or more EMRs in an RRC resume complete message (e.g., Msg5) in a RACH procedure. In some aspects, in the event that UE 120 switches from idle mode or inactive mode to connected mode, UE 120 may send an RRC setup complete message or an RRC recovery complete message (e.g., Msg5) including an indication that measurement reports are available to network node 110 during a RACH procedure. In this case, network node 110 may send a UE information request including a measurement report request to UE 120, and UE 120 may send measurement results associated with EMR measurements in one or more EMRs to network node 110 in a UE information response.

[0132] In some aspects, the UE 120 may determine that one or more EMR measurement results have not passed at least one of the first verification operation or the second verification operation. For example, the UE 120 may determine that the EMR measurement has not passed the first verification operation based at least in part on determining in the first verification operation that a difference between a first RSRP measurement or RSRQ measurement for a reference carrier in the EMR time window W0 and a second RSRP measurement or RSRQ measurement for a reference carrier in the first verification time window W1 does not satisfy a first threshold (e.g., abs[(most recent RSRP and / or RSRQ in W1)–(value stored in W0)]≥XdB). UE 120 may determine that one or more EMR measurements have not passed the second verification operation based at least in part on determining in the second verification operation that the difference between the highest RSRP or RSRQ measurement for a carrier using M Rx beams in the second verification time window W2 and the RSRP or RSRQ measurement for the carrier in the EMR window W0 does not meet a second threshold (e.g., abs[(highest RSRP and / or RSRQ among the M Rx beams in W2)–(saved RSRP and / or RSRQ for the same carrier in W0)]≥YdB). In some aspects, UE 120 may suppress sending measurement results associated with EMR measurements for one or more EMR carriers based at least in part on a determination that the EMR measurements have not passed at least one of the first verification operation or the second verification operation. In this case, UE 120 may discard the EMR configured to report the EMR measurements. In some aspects, in the event that UE 120 discards the EMR, UE 120 may send an explicit indication to network node 110 that the EMR is discarded, rather than sending the EMR to network node 110. In some aspects, based at least in part on a determination that the EMR measurement for one or more EMR carriers fails at least one of the first verification operation or the second verification operation, UE 120 may send to network node 110 an EMR including a measurement result for the EMR measurement and an indication (e.g., a flag) indicating that the EMR measurement failed the verification.

[0133] In some aspects, the above combination FIG. 6A to FIG. 6BThe operations described may be similarly applied to verify measurements performed by a UE 120 operating in any RRC state (e.g., RRC idle, RRC inactive, and / or RRC connected). For example, in some aspects, the operations described above may be similarly applied to verify measurements performed by a UE 120 operating in an RRC connected mode, where the interval between a measurement instance and a measurement result reporting instance satisfies (e.g., is greater than or equal to) a specific threshold. In this case, W0 may be redefined as a time window of a specific duration that ends at the time slot in which the last measurement resource is received before the corresponding result is scheduled for reporting. In this case, W1 may be redefined as a time window of a specific duration that begins before the reporting instance. In this case, W2 may be redefined as a time window of a specific duration that begins at or after the end of W1.

[0134] As indicated above, FIG. 6A to FIG. 6B are provided as examples. Other examples can be found in the FIG. 6A to FIG. 6B The content described is different.

[0135] FIG. 7A to FIG. 7B is a diagram illustrating an example 700 associated with a packet carrier for fast cell measurement according to the present disclosure. Fig. 7A As shown, example 700 includes communications between a network node 110 and a UE 120. In some aspects, the network node 110 and the UE 120 may be included in a wireless network, such as the wireless network 100. The network node 110 and the UE 120 may communicate via a wireless access link, which may include an uplink and a downlink.

[0136] like Fig. 7A And as indicated by reference numeral 705, the network node 110 may send configuration information for inter-frequency measurements and the UE 120 may receive the configuration information. In some aspects, the configuration information may indicate multiple target carriers for the inter-frequency measurements. In some aspects, the configuration information may be included in an RRC message. In some aspects, the inter-frequency measurements may be EMR measurements to be performed by the UE 120 in an idle mode or an inactive mode. In this case, the configuration information for the EMR measurements may be included in an RRC release message that triggers the UE 120 to switch from a connected mode to an idle mode or an inactive mode. In some aspects, the inter-frequency measurements may include inter-frequency cell reselection measurements to be performed by the UE 120 in an idle mode or an inactive mode. In some aspects, the inter-frequency measurements may be inter-frequency measurements to be performed in a connected mode (e.g., an RRC connected mode).

[0137] Multiple target carriers may be target carriers for which inter-frequency measurements (e.g., inter-frequency EMR measurements and / or inter-frequency cell reselection measurements) are to be performed. In some aspects, UE 120 may be configured with one or more target carrier groups. In some aspects, the grouping of target carriers for inter-frequency measurements may be explicitly signaled from network node 110 to UE 120. For example, the configuration information may indicate one or more target carrier groups. In this case, the configuration information may indicate which of the multiple target carriers are in each target carrier group. In some aspects, the configuration may not explicitly indicate the target carrier group. In this case, the target carrier group may be implicitly determined or selected by UE 120 based at least in part on the frequency position of the target carrier / cell for inter-frequency measurements. For example, the carriers in the group may be intra-band carriers in the same frequency band, or the carriers in the group may be intra-band continuous carriers in continuous frequencies in the same frequency band.

[0138] like Figure 7B As shown, the target carrier may be an FR2 carrier, and the target carrier group may include a first target carrier group (frequency group #1) (shown by reference numeral 722) and a second target carrier group (frequency group #2) (shown by reference numeral 724). The first group may include a first set of in-band contiguous carriers, and the second group may include a second set of in-band contiguous carriers. In some aspects, the first target carrier group and the second target carrier group may be inter-band target carrier groups. For example, the first group may be an in-band contiguous carrier set in a first frequency band, and the second group may be an in-band contiguous carrier set in a second frequency band. Alternatively, the first target carrier group and the second target carrier group may be in-band non-contiguous target carrier groups. For example, the first group may be a first in-band contiguous carrier set in a frequency band, and the second group may be a second in-band contiguous carrier set in the same frequency band as the first group but not contiguous with the first group.

[0139] In some aspects, the measurement cycle of one target frequency group may be configured differently than the measurement cycle of another target frequency group. Figure 7B The first target frequency group in the embodiment may be configured with a first measurement cycle that is different from the first measurement cycle configured for Figure 7B In some aspects, the configuration information may include a measurement configuration for the target carrier group, and the measurement configuration may indicate a configuration of the measurement cycle for each group. For example, the measurement configuration may be common within a target carrier group, but may be different for different target carrier groups.

[0140] In some aspects, each target carrier group may have a reference carrier (or reference cell). In some aspects, the reference carriers in the carrier group may be indicated by signaling from the network node 110 to the UE 120. For example, the configuration information may indicate the reference carriers for each carrier group. In some aspects, the UE 120 may autonomously select the reference carrier for the group from the target carriers in the group. Figure 7B As shown, the middle carrier of the first group is the reference carrier of the first group, and the middle carrier of the second group is the reference carrier of the second group.

[0141] Back to Fig. 7A , as shown by reference numeral 710, UE 120 may perform measurements for cell detection on reference carriers in a target carrier group in a first time window (W0-1). In some aspects, in the first time window W0-1, UE 120 may perform measurements only on reference carriers within the target carrier group. The measurements may include cell detection of reference carriers (e.g., reference target carriers) only. In some aspects, UE 120 may be able to perform measurements on reference carriers at a high rate in the first time window W0-1.

[0142] In some aspects, for each target carrier group, UE 120 may perform measurements for cell detection on a reference cell in a first time window W0-1 per group. Figure 7B As shown by reference numeral 726 in FIG. 1 , UE 120 may perform measurements for cell detection on reference carriers of the first target carrier group in the first time window W0-1. As shown by reference numeral 728, UE 120 may perform measurements for cell detection on reference carriers of the second target carrier group in the first time window W0-1. In some aspects, the measurement cycle of the first time window W0-1 may be for different groups (e.g., for Figure 7B The first and second groups in are configured differently.

[0143] Back to Fig. 7AAs shown by reference numeral 715, the UE 120 may selectively perform inter-frequency measurements for the target carrier group in the second time window (W0-2) based at least in part on the cell detection on the reference carrier in the target carrier group. In some aspects, for the target carrier group, if the reference carrier / cell is not detected within the duration of the first time window W0-1, the UE 120 may not continue to perform inter-frequency measurements for other carriers in the group in the second time window W0-2. For example, in conjunction with a determination that no cell is detected on the reference carrier in the first time window W0-1, the UE 120 may suppress performing (e.g., choose not to perform) inter-frequency measurements on the target carrier group in the second time window W0-2. Additionally or alternatively, in conjunction with a determination that the signal strength of the cell detected on the reference carrier in the first time window W0-1 does not meet (e.g., is less than or equal to) a threshold, the UE 120 may suppress performing inter-frequency measurements on the target carrier group in the second time window W0-2.

[0144] In some aspects, if a reference carrier / cell is detected within the duration of the first time window W0-1, the UE 120 may continue to perform (e.g., select to perform) inter-frequency frequency measurements for the target carriers in the group in the second time window W0-2. For example, in conjunction with a determination that a cell with a signal strength above a threshold is detected on the reference carrier in the first time window W0-1, the UE 120 may perform inter-frequency measurements on the carrier group in the second time window W0-2. When the UE 120 successfully detects a cell on the reference carrier, the UE 120 may obtain automatic gain control (AGC) information, time and frequency synchronization information, UE Rx beam information, and network node Tx beam information (e.g., SSB-ID) from the detected cell on the reference carrier. In some aspects, the UE 120 may perform inter-frequency measurements on the target carriers in the group based at least in part on the obtained AGC, time and frequency synchronization information, and / or UE 120 Rx beam information from the reference carrier. In some cases, the network node Tx beam information (e.g., SSB-ID) from the cell detected on the reference carrier may be different from the network node Tx beams of other target carriers in the group. In some other cases, depending on the network configuration, it may be assumed that the network node Tx beam (e.g., SSB-ID) is common to all carriers in the target carrier group. In this case, UE 120 may perform inter-frequency measurements based at least in part on the network node Tx beam (e.g., SSB-ID) determined from the reference cell.

[0145] In some aspects, UE 120 may select to perform or refrain from performing inter-frequency measurements in each set of second time windows W0-2 for each target carrier group based at least in part on cell detection on the corresponding reference carrier in the first time window W0-1 for each carrier group. Figure 7B And as indicated by reference numeral 730, in conjunction with detecting a cell on the reference carrier in the first time window W0-1 (e.g., having a signal strength greater than a threshold), the UE 120 may perform inter-frequency measurements for the first target carrier group in the second time window W0-2. As indicated by reference numeral 732, in conjunction with a determination that no cell is detected on the reference carrier in the first time window W0-2 (e.g., having a signal strength greater than a threshold), the UE 120 may refrain from performing inter-frequency measurements for the second target carrier group in the second time window W0-2.

[0146] In some aspects, different measurement cycles may be configured for the first time window W0-1 and the second time window W0-2. In some aspects, in the case where the configured inter-frequency measurements are inter-frequency EMR measurements to be performed by the UE 120 when the UE 120 is operating in an idle mode or an inactive mode, in combination with FIG. 7A to FIG. 7B The described operations can be combined with FIG. 6A to FIG. 6B For example, the EMR measurements in the EMR window W0 and / or the EMR timer duration may be combined as shown in FIG. FIG. 7A to FIG. 7B In this case, W0-1 and W0-2 may be the first and second parts of the EMR window W0 or the first and second parts of the EMR timer duration.

[0147] Return to Fig. 7A , as indicated by reference numeral 720, UE 120 may send a measurement result of the inter-frequency measurement performed on the target carrier group or an indication that there is no measurement result for the target carrier group to network node 110. In some aspects, when UE 120 performs inter-frequency measurement for the carrier group in the second time window W0-2, UE 120 may send an indication of the inter-frequency measurement performed on the target carrier group, and network node 110 may receive the indication. For example, UE 120 may send a measurement report (e.g., an EMR or another measurement report) including the measurement result of the inter-frequency measurement performed on the target carrier group to network node 110.

[0148] In some aspects, when UE 120 refrains from performing inter-frequency measurements on the target carrier group in the second time window (W0-2), UE 120 may refrain from sending inter-frequency measurements for the target carrier group to network node 110. For example, UE 120 may discard a measurement report configured to report inter-frequency measurements for the target carrier group. In some aspects, when UE 120 refrains from sending inter-frequency measurements for the target carrier group to network node 110, UE 120 may send an indication (e.g., in a measurement opportunity) to network node 110 that inter-frequency measurements were not performed on the carrier group, instead of a measurement report. For example, the indication may indicate that the measurement report for the inter-frequency measurements of the carrier group has been discarded by UE 120.

[0149] In some aspects, when UE 120 refrains from performing inter-frequency measurements on the target carrier group in the second time window W0-2, UE 120 may send (e.g., in a measurement report) a previous measurement (e.g., performed in a previous measurement occasion) for the target carrier group. In this case, UE 120 may send the measurement report together with an indication (e.g., a flag) indicating that the measurement is old and / or that UE 120 did not perform inter-frequency measurements in the measurement occasion for which the measurement is reported.

[0150] In some aspects, UE 120 may continue to monitor the reference carrier of the group while selectively skipping inter-frequency measurements for other target carriers in the group based at least in part on the measurements of the reference carrier. For example, UE 120 may perform measurements (e.g., RSRP or RSRQ measurements) on the reference carrier in a second measurement opportunity after performing inter-frequency measurements on the carrier group in a first measurement opportunity. UE 120 may compare the measured value (e.g., RSRP or RSRQ value) on the reference carrier in the second measurement opportunity with the previously measured value (e.g., previous RSRP or RSRQ value) on the reference carrier in the first measurement opportunity, and UE 120 may refrain from performing inter-frequency measurements on the target carrier group in the second measurement opportunity based at least in part on the difference between the measured values ​​on the reference carrier in the second measurement opportunity and the first measurement opportunity being less than or equal to a threshold.

[0151] As indicated above, FIG. 7A to FIG. 7B are provided as examples. Other examples can be found in the FIG. 7A to FIG. 7B The content described is different.

[0152] Figure 8 is a diagram illustrating an example process 800, performed, for example, by a UE, according to the present disclosure. Example process 800 is an example in which a UE (eg, UE 120) performs operations associated with early measurement report validation for non-connected mode UEs.

[0153] like Figure 8 As shown, in some aspects, process 800 may include performing EMR measurements for a first set of carriers in an EMR time window (block 810). Fig.10 The communication manager 140 and / or the measurement component 1008 depicted in FIG. 1004 may perform EMR measurements for the first set of carriers in the EMR time window, as described above.
