Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatuses for mobility enhancement with coverage and capacity optimization. Background Art

[0002] 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).

[0003] 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 sidelink (SL), a WiFi link, or a Bluetooth link).

[0004] 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 an enhancement set to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using 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, and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. 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

[0027] 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. On the contrary, 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 present 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 that is practiced using other structures, functions, or structures and functions in addition to 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 claims.

[0028] 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 can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0029] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technologies (RATs), various aspects of the present disclosure may be applicable to other RATs, such as 3G RATs, 4G RATs, and / or post-5G RATs (e.g., 6G).

[0030] Figure 1 1 is a diagram illustrating an example of a wireless network 100. The wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network or elements of a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. 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), or other entities. The network node 110 is an example of a network node communicating with the UE 120. As shown, 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 RAN node (e.g., within a single device or unit). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated 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)).

[0031] 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. For example, the network node 110 may include 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.

[0032] 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 or a 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, or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) 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 residence) 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 1In 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).

[0033] In some aspects, the term "base station" or "network node" may refer to a clustered 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 number 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 repeat the execution of 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 the other. In this way, a single device may include more than one base station.

[0034] The wireless network 100 may include one or more relay stations. A relay station is a network node that receives transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmits 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, 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 communications 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.

[0035] 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, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different effects on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 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 to 2 watts).

[0036] 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 backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0037] UE 120 can be dispersed throughout wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, access terminals, terminals, mobile stations, or subscriber units. UE 120 can 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 device, 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, or a satellite radio), a vehicle-mounted component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, or any other suitable device configured to communicate via a wireless or wired medium.

[0038] Some UE 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UE. MTC UE or eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor or a location tag, which may communicate with a network node, another device (e.g., a remote device) or some other entity. Some UE 120 may be considered as an Internet of Things (IoT) device, or may be implemented as a NB-IoT (narrowband IoT) device. Some UE 120 may be considered as customer premises equipment. UE 120 may be included inside a housing 284, which houses components of UE 120, such as a processor component 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, or electrically coupled.

[0039] 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 also be referred to as a radio technology or air interface. Frequency may also be referred to as a carrier or frequency channel. In a given geographic area, each frequency may support a single RAT to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0040] 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), or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by network node 110.

[0041] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, or channels by frequency or wavelength. For example, 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 range designations FR1 (410 MHz–7.125 GHz) and FR2 (24.25 GHz–52.6 GHz). 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. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0042] 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 (7.125GHz–24.25GHz). The bands falling within FR3 can inherit FR1 characteristics or FR2 characteristics, and thus the features of FR1 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 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz–71GHz), FR4 (52.6GHz–114.25GHz), and FR5 (114.25GHz–300GHz). Each of these higher frequency bands falls within the EHF band.

[0043] With these examples in mind, unless otherwise specifically stated, if the term "sub-6 GHz" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, frequencies that may be within FR1, or frequencies that may include mid-band frequencies. Additionally, unless otherwise specifically stated, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, frequencies that may be within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies that 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, or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0044] In some aspects, UE 120 may include a communications manager 140. As described in greater detail elsewhere herein, communications manager 140 may receive configuration information indicating a plurality of configurations indicating at least one of: a plurality of values ​​for a measurement reporting event, or a plurality of scaling factors for a metric associated with a measurement reporting event; receive an indication of a selected configuration from the plurality of configurations; and measure a reference signal based at least in part on the selected configuration. Additionally or alternatively, communications manager 140 may perform one or more other operations described herein.

[0045] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send configuration information indicating a plurality of configurations indicating at least one of: a plurality of values ​​for a measurement reporting event, or a plurality of scaling factors for a metric associated with the measurement reporting event; send an indication of a selected configuration of the plurality of configurations for the UE; and receive a measurement report associated with the UE based at least in part on the selected configuration. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0046] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 Different than described.

[0047] 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. 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 antenna 234 and 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.

[0048] At the network node 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may use one or more channel quality indicators (CQIs) received from the UE 120 to select one or more modulation and coding schemes (MCSs) for the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 using the MCS selected for the UE 120 and may provide data symbols to the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, 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., pre-coding) on ​​data symbols, control symbols, overhead symbols, 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, or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0049] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 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, 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, or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in a housing.

[0050] 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.

[0051] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or may be included in one or more antenna panels, one or more antenna groups, one or more group antenna elements, or one or more antenna arrays, etc. An antenna panel, antenna group, set of antenna elements, or antenna array may include one or more antenna elements (in a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or coupled to one or more transmit or receive components (such as Figure 2 One or more antenna elements of one or more components).

[0052] 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, 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, or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the processes described herein.

[0053] At the network node 110, uplink signals from the UE 120 or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232, shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted via 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 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, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the processes described herein.

[0054] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other components of the network node 110 may perform one or more techniques associated with mobility enhancement, as described in more detail elsewhere herein. For example, 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 6 The process of 600 Figure 7 10 and / or operations of process 700 and / or 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, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The process 700 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.

[0055] In some aspects, the UE 120 includes means for receiving configuration information indicating a plurality of configurations indicating at least one of: a plurality of values ​​for a measurement reporting event, or a plurality of scaling factors for a metric associated with a measurement reporting event; means for receiving an indication of a selected configuration from the plurality of configurations; and / or means for measuring a reference signal based at least in part on the selected configuration. Means for the UE 120 to perform operations described herein may include, for example, one or more of the communications manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0056] In some aspects, a network node (e.g., network node 110) includes means for sending configuration information indicating a plurality of configurations indicating at least one of: a plurality of values ​​for a measurement reporting event, or a plurality of scaling factors for a metric associated with a measurement reporting event; means for sending an indication of a selected configuration of the plurality of configurations for a UE; and / or means for receiving a measurement report associated with the UE based at least in part on the selected configuration. In some aspects, means for a network node to perform operations described herein may include, for example, one or more of a communications manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0057] 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 with respect to 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.

[0058] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different than described.

[0059] Figure 3 is a diagram illustrating an example 300 of dynamic network-side antenna adaptation according to the present disclosure.

[0060] For various reasons, including climate change mitigation and network cost reduction, energy conservation and / or energy efficiency measures are expected to have increasing importance in wireless network operations. For example, although NR generally provides significant energy efficiency improvements per gigabyte over previous generations (e.g., LTE), the adoption of new NR use cases and / or millimeter wave frequencies requires more network sites and more network antennas, which may potentially lead to more efficient cellular networks that still have higher energy requirements and / or cause more emissions than previous generations. In addition, energy accounts for a significant proportion of the cost of operating a cellular network. For example, according to some estimates, energy costs are close to 23% of the total cost of operating a cellular network, sales, general and administrative (SG&A) expenses and other costs account for about 75%, and more than 90% of network operating costs are spent on energy (e.g., fuel and electricity consumption). Most energy consumption and / or energy costs are associated with powering the RAN, which accounts for about 30% of the energy consumed by wireless networks, with data centers and fiber transmission accounting for a smaller share. Therefore, measures to increase energy conservation and / or energy efficiency in wireless networks are important factors that can drive the adoption and / or expansion of cellular networks.

[0061] One way to increase energy efficiency in the RAN may be to use dynamic network antenna adaptation in base stations that communicate using massive MIMO technology that tends to consume a lot of power. For example, in an LTE network, a base station that supports massive MIMO technology may communicate using a baseband unit (BBU) that processes baseband signals and communicates with the core network through a physical interface and a remote radio unit (RRU) that performs transmit and receive radio frequency (RF) functions. In an LTE network, the per-cell power consumption (e.g., in watts) of the RRU is slightly larger than that of the BBU, and the per-cell power consumption does not vary significantly with cell load. However, in an NR network, network nodes that support massive MIMO technology may communicate using a BBU and an active antenna unit (AAU) that consumes significantly more power than the BBU and RRU in an LTE base station (e.g., because NR operates at a higher data rate and / or higher bandwidth than LTE). For example, when the cell load is low (e.g., 0%), the BBU and AAU of the NR network node or network node group may consume 2.4 times the power of the BBU and RRU in the LTE base station, when the cell load is medium (e.g., 30%), the BBU and AAU of the NR network node or network node group may consume 2.6 times the power of the BBU and RRU in the LTE base station, or when the cell load is high (e.g., 100%), the BBU and AAU of the NR network node or network node group may consume 3 times the power of the BBU and RRU in the LTE base station, where "cell load" generally refers to the proportion of frequency resources within a carrier that is being utilized at a given time. In addition, in an NR network node, the AAU generally consumes more power than the BBU, and the proportion of power consumption attributable to the AAU increases as the cell load increases (e.g., because the BBU has a relatively static power consumption regardless of the cell load). Therefore, in an NR base station supporting massive MIMO technology, the AAU represents the highest energy consuming component.

[0062] Therefore, if Figure 3 Also shown by reference numeral 310, a network node supporting massive MIMO communications may enable dynamic network antenna adaptation based on current and / or predicted cell loads to improve energy efficiency. For example, to enable massive MIMO communications, a network node may typically need to have multiple co-located antenna panels, each antenna panel including multiple antenna ports. For example, in Figure 3 , reference numeral 320 depicts an example antenna panel including four (4) sub-panels, each sub-panel including a number of antenna ports (shown as gray and black cross-hatched lines) that are each mapped to one or more physical antennas, wherein Figure 3Each diagonal line in corresponds to one (1) antenna port and the color of the diagonal line indicates the polarization of the antenna port (e.g., horizontal or vertical). In general, each antenna panel is equipped with various power amplifiers and antenna subsystems that consume a lot of power. Therefore, in order to save power or otherwise utilize energy more efficiently, the network node may dynamically adapt the antenna configuration based on current and / or predicted cell load. For example, when the cell load is high, the network node may turn on all (or most) antenna panels, sub-panels and / or ports to increase capacity, and when the cell load is low, the network node may turn off some antenna panels, sub-panels and / or ports to reduce energy consumption. In some examples, the network node may perform dynamic beam adaptation, in which one or more beams are turned off (such as based at least in part on the load on the one or more beams) to reduce energy consumption.

[0063] However, in the case where the network node supports dynamic network antenna adaptation (e.g., to use energy more efficiently based on cell load or other factors), changes in antenna configuration parameters may result in changes in coverage of the network node. For example, dynamic network antenna adaptation or dynamic beam adaptation for network energy saving may result in cell coverage loss due to reduced transmit power and beamforming gain of the network node. Some networks may allow a cell to compensate for the coverage loss of another cell (referred to as coverage and capacity optimization (CCO)). An updated antenna or beam configuration may be used to schedule an updated antenna or beam configuration before the actual service arrives (e.g., based at least in part on UE feedback, such as predicted service and channel state information (CSI) reports). In some cases, a reduction in coverage at a serving cell may cause the UE to perform a handover to a neighboring cell after the serving cell has completed the coverage reduction. However, such a handover may result in UE communication interruption, delay, and unreliability. This may be particularly impactful for UEs with time-critical or data-sensitive services such as extended reality (XR), ultra-reliable communications, low-latency communications, etc.

[0064] Some techniques and devices described herein provide for the selection of a threshold for a measurement reporting event, and / or a selection of a scaling factor to be applied to a metric associated with a measurement reporting event. A measurement reporting event may be associated with a handover of a UE. The threshold or scaling factor may be selected from a plurality of configured thresholds or scaling factors (such as a plurality of configurations of the threshold or scaling factor). In some examples, a network node may select a threshold or scaling factor based at least in part on a prediction of a coverage change. For example, when a reduction in coverage of a network node is predicted (such as due to dynamic antenna or beam adaptation), the network node may select a threshold or scaling factor that may trigger an earlier handover. In this way, interruptions, delays, and unreliability of communications of a UE are reduced by triggering a handover before the coverage of the network node is reduced due to dynamic antenna or beam adaptation. In addition, these techniques (selecting a threshold or scaling factor that triggers a handover earlier than another threshold or scaling factor) may be applied to situations where the activity of a network node (e.g., cell load) is to be reduced, regardless of whether the network node predicts a coverage change.

[0065] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different than described.

[0066] Figure 4 4 is a diagram illustrating an example 400 of signaling associated with measurement report event adjustment according to the present disclosure. As shown, example 400 includes a UE (e.g., UE 120) and a network node (e.g., network node 110). The network node may include a serving cell of the UE. A serving cell is a cell on which the UE has an active connection (e.g., a radio resource control (RRC) connection) with the network node. In some aspects, the network node may include multiple network nodes, such as a CU and a DU, a CU and a RU, a DU and a RU, or different combinations of network nodes.

[0067] like Figure 4 4 and as shown by reference numeral 410, a network node (e.g., a CU and / or a DU) may send configuration information, and a UE may receive the configuration information. For example, the configuration information may be sent via control signaling such as RRC signaling. The configuration information may include a plurality of configurations. One of the plurality of configurations may identify a value for a measurement report event. For example, the value may be a threshold for the measurement report event, such as a threshold of a metric determined at least in part based on a measurement reference signal, or a threshold time length based thereon to trigger a measurement report event. Thus, the configuration information may include a plurality of values ​​for the measurement report event.

[0068] In some aspects, the configuration information may include a measurement configuration or multiple measurement configurations, which identify or include multiple configurations. The measurement configuration may identify the configuration of one or more neighboring measurements to be performed by the UE 120. In some aspects, the one or more neighboring measurements may be associated with a corresponding target carrier, cell, or frequency. The neighboring measurements may include, for example, RSRP measurements (e.g., synchronization signal RSRP (SS-RSRP) measurements), RSRQ measurements (e.g., synchronization signal RSRQ (SS-RSRQ) measurements), signal to interference plus noise ratio (SINR) values ​​(e.g., synchronization signal SINR (SS-SINR) measurements), etc.

[0069] A measurement configuration is a configuration provided from a network node to a UE to configure the UE to perform measurements, such as NR measurements, inter-radio access technology measurements of Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access (E-UTRA) frequencies, and the like. The measurement configuration may configure the UE to report measurement information based at least in part on measurement resources such as synchronization signal blocks (SSBs), channel state information reference signal (CSI-RS) resources, channel state information interference management (CSI-IM) resources, and the like. The measurement configuration may include a measurement object, a reporting configuration, a measurement identifier, a quantity configuration, a measurement gap configuration, or a combination thereof. The measurement object may provide a list of objects (e.g., frequency resources, time resources, and subcarrier spacing of reference signals) on which the UE may perform measurements for intra-frequency and inter-frequency operations. The reporting configuration may indicate a reporting criterion (e.g., a value associated with a measurement reporting event), a reference signal type, and / or a reporting format for the measurement object. The measurement identifier may link the measurement object to the reporting configuration. The quantity configuration may describe filter coefficients for layer 3 filtering used for the measurement. The measurement gap configuration may indicate the gaps over which the UE 120 is to perform measurements. In some aspects, UE 120 may determine measurement information based at least in part on one or more measurement configurations and / or may report measurement information based at least in part on one or more measurement configurations.

[0070] The measurement reporting events may include, for example, an A1 reporting event (e.g., a metric associated with a serving cell becomes better than a threshold), an A2 reporting event (e.g., a metric associated with a serving cell becomes worse than a threshold), an A3 reporting event (e.g., a metric associated with a neighboring cell becomes better than a special cell (SPCell) by a threshold), an A4 reporting event (e.g., a metric associated with a neighboring cell becomes better than a threshold), an A5 reporting event (e.g., a metric associated with a special cell is worse than a first threshold, and a metric associated with a neighboring cell is better than a second threshold), an A6 reporting event (e.g., a metric associated with a neighboring cell becomes better than a metric associated with a secondary cell by a threshold), a B1 reporting event (e.g., a metric associated with a neighboring inter-system cell becomes better than a threshold), or a B2 reporting event (e.g., a metric associated with a primary serving cell is worse than a first threshold, and a metric associated with a neighboring inter-system cell is better than a second threshold). The value associated with a measurement reporting event (also referred to herein as a reporting criterion) may indicate a threshold associated with the measurement reporting event (e.g., a time-based threshold indicating a threshold time length, or a threshold of a metric associated with the measurement reporting event), or a first threshold and / or a second threshold associated with the measurement reporting event, such as the thresholds described with respect to the reporting events above. The network node may configure multiple values ​​associated with the measurement reporting event (or a corresponding multiple values ​​for each of a plurality of measurement reporting events). For example, a single reporting configuration may include multiple reporting criteria, or a measurement configuration may include multiple reporting configurations.

[0071] In some aspects, multiple configurations may be shared among multiple cells. For example, each neighboring cell of a UE may be associated with the same multiple configurations, meaning that the value of the measurement reporting event is selected from the same multiple values ​​for any neighboring cell. In some aspects, multiple configurations may be cell-specific. For example, a first cell may be associated with a first multiple configuration (from which the value of the threshold of the measurement reporting event of the first cell may be selected), and a second cell may be associated with a second multiple configuration (from which the value of the threshold of the measurement reporting event of the second cell may be selected).

[0072] In some aspects, multiple configurations may be shared across two or more types of measurements. For example, the same multiple configurations may be applied to a threshold associated with a SINR metric, a threshold associated with an RSRP metric, and a threshold associated with an RSRQ metric. In some aspects, multiple configurations may be specific to the type of measurement. For example, a first multiple configuration may be applied to a threshold associated with an SINR metric, and a second multiple configuration may be applied to a threshold associated with an RSRP metric.

[0073] As shown by reference numeral 420, a network node (e.g., a CU, DU, and / or RU) may identify a coverage change. For example, the network node may identify a predicted coverage change for a serving cell associated with the network node. In some aspects, the network node may identify a predicted coverage change based at least in part on dynamic network antenna adaptation and / or dynamic beam adaptation. For example, the network node may identify that the network node will deactivate one or more antennas, antenna sub-panels, or antenna panels at a future time. As another example, the network node may identify that the network node will deactivate one or more beams at a future time. Thus, the network node may identify a predicted coverage change that will be caused by the deactivation of one or more beams, antennas, antenna sub-panels, or antenna panels.

[0074] As shown by reference numeral 430, in some examples, a network node (e.g., a CU and / or DU) may send an indication of a predicted coverage change, and a UE may receive the indication of the predicted coverage change. For example, a serving cell associated with the network node may announce an indicator indicating the "next step" of the serving cell. In some aspects, a network node (e.g., a CU and / or DU) may provide an indication sent by another network node (e.g., a DU and / or RU). In some aspects, the indication may indicate that cell coverage is about to change (e.g., increase or decrease), so that the UE may consider whether to stay in the serving cell or hand over to another cell. The indication shown by reference numeral 430 may be sent using RRC signaling, a medium access control control element (MAC-CE), or downlink control information (DCI). The indication shown by reference numeral 430 may also be described elsewhere herein. Figure 5 is implemented in Example 500.

[0075] As shown by reference numeral 440, a network node (e.g., a CU, a DU, and / or a RU) may send an indication of a selected configuration, and a UE may receive an indication of the selected configuration. The indication of the selected configuration may be sent using layer 1 signaling (e.g., DCI), layer 2 signaling (e.g., MAC-CE), or a combination thereof (e.g., down-selection from a plurality of configurations via MAC-CE signaling, and then selecting one of the down-selected configurations via DCI signaling). In some aspects, a network node (e.g., a CU and / or a DU) may provide an indication sent by another network node (e.g., a DU and / or a RU). In some aspects, the indication may indicate a single selected configuration. In some other aspects, the indication may indicate a plurality of selected configurations, such as a first configuration associated with a first cell and a second configuration associated with a second cell, or a first configuration associated with a first type of measurement and a second configuration associated with a second type of measurement, or a combination thereof. In some aspects, a network node may select a selected configuration. For example, a network node may select a selected configuration based at least in part on a predicted coverage change. More specifically, in the case of a predicted coverage change involving a coverage decrease, the network node may select a threshold or scaling factor that is likely to trigger a handover earlier than a threshold or scaling factor associated with a coverage increase (such as due to dynamic antenna or beam adaptation).

[0076] As indicated by reference numeral 450, the UE may measure reference signals of the UE's serving cell and / or one or more neighboring cells. In some aspects, the UE may measure the reference signal based at least in part on the selected configuration (e.g., the UE may determine whether a metric derived from the measurement satisfies a selected value indicated by the selected configuration, and / or may determine whether a threshold indicated by a measurement reporting event is met within a threshold time length indicated by the selected value). To measure the reference signal, the UE may determine a metric (e.g., an SINR metric, an RSRP metric, an RSRQ metric, etc.) of a resource identified by one or more measurement configurations associated with the reference signal. The reference signal may include any reference signal used for radio resource management (RRM) measurements and / or that may be indicated by a measurement configuration, such as a CSI-RS, SSB, etc. In some aspects, the UE may apply a scaling factor to one or more metrics determined based at least in part on the measurement, such as in combination with the measurement configuration. Figure 5 Described in more detail.

[0077] As shown by reference numeral 460, the UE may send a measurement report and the network node may receive the measurement report. For example, the UE may send one or more measurement reports and the network node may receive one or more measurement reports. In some aspects, the measurement report (or the sending of the measurement report) may be based at least in part on a selected value corresponding to the configuration selected at reference numeral 440. For example, the UE may send the measurement report based at least in part on satisfying a threshold value of a metric associated with a measurement report event (as indicated by the selected value). As another example, the UE may send the measurement report based at least in part on satisfying a threshold time length associated with the measurement report event (as indicated by the selected value). The measurement report may indicate a cell that satisfies a reporting criterion for the relevant measurement report event. For example, the measurement report may identify a neighboring cell whose metric satisfies a threshold value associated with the reporting criterion. In some aspects, a first network node (e.g., RU) may receive the measurement report and may provide the measurement report to another network node (e.g., CU and / or DU). In some aspects, a first network node (eg, a RU and / or a DU) may receive and process the measurement report and may provide the measurement information to a second network node (eg, a CU and / or a DU).

[0078] Thus, the UE may identify a suitable neighboring cell for handover based at least in part on the selected configuration. In some aspects, the selected configuration may enable the UE to select a suitable neighboring cell faster than when the UE uses another configuration to select a neighboring cell. For example, the selected configuration may be associated with a lower metric threshold and / or a shorter threshold time length than another configuration. In this example, when the network node has (at reference numeral 420) identified the coverage change as a coverage decrease, the selected configuration may be used, and when no coverage decrease is identified or when an increase in coverage is identified, another configuration may be used.

[0079] As shown by reference numeral 470, in some aspects, the UE and the network node may perform a handover to the cell indicated by the measurement report. For example, the network node (or a network entity associated with the network node) may trigger a handover of the UE from a serving cell associated with the network node to a neighboring cell (which may be associated with the network node or another network node). In some aspects, the network node (or a network entity associated with the network node) may reconfigure the neighboring cell to increase coverage of the neighboring cell (such as based at least in part on a coverage change identifying the serving cell). In some aspects, the network node may perform dynamic network antenna adaptation or dynamic beam adaptation as described with respect to reference numeral 420 (e.g., after a handover of the UE).

[0080] In this way, interruptions, latency, and unreliability of the UE's communications are reduced by, for example, triggering a handover before the coverage of a network node decreases due to dynamic antenna or beam adaptation.

[0081] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 Different than described.

[0082] Figure 5 is a diagram illustrating an example 500 of signaling associated with adjustment of a metric associated with a measurement reporting event according to the present disclosure. As shown, example 500 includes a UE (e.g., UE 120) and a network node (e.g., network node 110). The network node may include a serving cell of the UE. In some aspects, the network node may include multiple network nodes, such as a CU and a DU, a CU and a RU, a DU and a RU, or different combinations of network nodes.

[0083] like Figure 5 , and as shown by reference numeral 510, a network node (e.g., a CU and / or a DU) may send configuration information, and a UE may receive the configuration information. For example, the configuration information may be sent via control signaling such as RRC signaling. The configuration information may include a plurality of configurations. One of the plurality of configurations may identify a scaling factor for a metric associated with a measurement report event. Thus, the configuration information may include a plurality of scaling factors for a measurement report event. The scaling factor may be applied to a metric to determine a scaled metric for determining whether the scaled metric triggers a measurement report event.

[0084] In some aspects, the configuration information may include a measurement configuration or multiple measurement configurations, which identify or include multiple configurations. The measurement configuration may identify the configuration of one or more neighbor measurements to be performed by the UE 120. In some aspects, the one or more neighbor measurements may be associated with a corresponding target carrier, cell, or frequency. The neighbor measurements may include, for example, RSRP measurements (e.g., SS-RSRP measurements), RSRQ measurements (e.g., SS-RSRQ measurements), SINR values ​​(e.g., SS-SINR measurements), etc.

[0085] A measurement configuration is a configuration provided from a network node to a UE to configure the UE to perform measurements, such as NR measurements, inter-radio access technology measurements of E-UTRA frequencies, and the like. The measurement configuration may configure the UE to report measurement information based at least in part on measurement resources such as SSBs, CSI-RS resources, CSI-IM resources, and the like. The measurement configuration may include a measurement object, a reporting configuration, a measurement identifier, a quantity configuration, a measurement gap configuration, or a combination thereof. The measurement object may provide a list of objects on which the UE may perform measurements for intra-frequency and inter-frequency operations. The reporting configuration may indicate a reporting criterion, a reference signal type, and / or a reporting format for the measurement object. The measurement identifier may link the measurement object to the reporting configuration. The quantity configuration may describe the filter coefficients for layer 3 filtering used for the measurement. The measurement gap configuration may indicate the gaps in which the UE 120 is to perform measurements. In some aspects, the UE 120 may determine the measurement information based at least in part on one or more measurement configurations, and / or may report the measurement information based at least in part on one or more measurement configurations. In some aspects, the measurement configuration may include information indicating multiple scaling factors. In some other aspects, the information indicating the multiple scaling factors may be sent separately from the measurement configuration (eg, and may identify the measurement configuration to which the multiple scaling factors are to be applied).

[0086] The network node may configure a plurality of scaling factors associated with a measurement reporting event (or a respective plurality of scaling factors for each of a plurality of measurement reporting events). For example, a single reporting configuration may be associated with a plurality of scaling factors (one of which may be selected as described elsewhere herein), or a measurement configuration may include a plurality of reporting configurations, each associated with a scaling factor.

[0087] In some aspects, multiple configurations may be shared among multiple cells. For example, each neighboring cell of a UE may be associated with the same multiple configurations, meaning that the scaling factor is selected from the same multiple values ​​for any neighboring cell. In some aspects, multiple configurations may be cell-specific. For example, a first cell may be associated with a first multiple configuration (from which the scaling factor associated with the first cell may be selected), and a second cell may be associated with a second multiple configuration (from which the scaling factor associated with the second cell may be selected).

[0088] In some aspects, multiple configurations may be shared among two or more types of measurements. For example, the selected scaling factor may be selected from the same multiple scaling factors for SINR metrics, RSRP metrics, and RSRQ metrics. In some aspects, multiple configurations may be specific to the type of measurement. For example, the selected scaling factor may be selected from a first plurality of configurations for SINR metrics and from a second plurality of configurations for RSRP metrics.

[0089] As shown by reference numeral 520, a network node (e.g., a CU, DU, and / or RU) may identify a coverage change. For example, the network node may identify a predicted coverage change for a serving cell associated with the network node. In some aspects, the network node may identify a predicted coverage change based at least in part on dynamic network antenna adaptation and / or dynamic beam adaptation. For example, the network node may identify that the network node will deactivate one or more antennas, antenna sub-panels, or antenna panels at a future time. As another example, the network node may identify that the network node will deactivate one or more beams at a future time. Thus, the network node may identify a predicted coverage change that will be caused by the deactivation of one or more beams, antennas, antenna sub-panels, or antenna panels.

[0090] As shown by reference numeral 530, a network node (e.g., a CU, DU, and / or RU) may send an indication of a selected configuration, and a UE may receive an indication of the selected configuration. For example, the selected configuration may indicate a selected scaling factor from a plurality of scaling factors. The indication of the selected configuration may be sent using layer 1 signaling (e.g., DCI), layer 2 signaling (e.g., MAC-CE), or a combination thereof (e.g., selecting from a plurality of configurations via MAC-CE signaling, and then selecting one of the selected configurations via DCI signaling). In some aspects, a network node (e.g., a CU and / or DU) may provide an indication sent by another network node (e.g., a DU and / or RU). In some aspects, the indication may indicate a single selected configuration. In some other aspects, the indication may indicate multiple selected configurations, such as a first configuration associated with a first cell and a second configuration associated with a second cell, or a first configuration associated with a first type of measurement and a second configuration associated with a second type of measurement, or a combination thereof.

[0091] As indicated by reference numeral 540, the UE may measure reference signals of the UE's serving cell and / or one or more neighboring cells. As further shown, the UE may apply the selected scaling factor to a metric determined at least in part based on the reference signal. In this example, if the scaling factor is 1.25 and the metric is an SINR of 13dB, the UE may determine that the scaled metric is 1.25×13dB=16.25dB. In some aspects, the UE may measure the reference signal based at least in part on the selected configuration (e.g., the UE may apply the selected scaling factor to a metric determined at least in part based on the reference signal). In order to measure the reference signal, the UE may determine a metric (e.g., an SINR metric, an RSRP metric, an RSRQ metric, etc.) of a resource identified by one or more measurement configurations associated with the reference signal. The reference signal may include any reference signal used for RRM measurement and / or indicated by a measurement configuration, such as CSI-RS, SSB, etc. As described above, in some aspects, the UE may apply a scaling factor based at least in part on which cell sends a reference signal (e.g., a scaling factor associated with the cell, or whether the cell is a serving cell or a neighboring cell), a measurement type associated with the reference signal, or a combination thereof. For example, the UE may be configured with multiple scaling factors applied to different cells, and may apply a scaling factor associated with the cell from which the reference signal is received. As another example, the UE may apply a first scaling factor to a serving cell and a second scaling factor to a neighboring cell. As another example, the UE may be configured with multiple scaling factors for different types of measurements, and may apply a scaling factor associated with a measurement type performed at least in part based on a reference signal.

[0092] As shown by reference numeral 550, the UE may send a measurement report and the network node may receive the measurement report. For example, the UE may send one or more measurement reports and the network node may receive one or more measurement reports. In some aspects, the measurement report (or the sending of the measurement report) may be based at least in part on a scaling factor corresponding to the configuration selected at reference numeral 530. For example, the UE may send the measurement report based at least in part on the scaled metric (scaled using the scaling factor corresponding to the selected configuration) satisfying a threshold associated with a measurement report event. The measurement report may indicate a cell that satisfies a reporting criterion for the relevant measurement report event. For example, the measurement report may identify a neighboring cell whose metric satisfies a threshold associated with the reporting criterion. In some aspects, a first network node (e.g., RU) may receive the measurement report and may provide the measurement report to another network node (e.g., CU and / or DU). In some aspects, the first network node (e.g., RU and / or DU) may receive and process the measurement report and may provide measurement information to a second network node (e.g., CU and / or DU).

[0093] Thus, the UE may identify a suitable neighboring cell for handover based at least in part on the selected configuration. In some aspects, the selected configuration may enable the UE to select a suitable neighboring cell faster than when the UE uses another configuration to select a neighboring cell. For example, the selected configuration may cause a metric to be adjusted so that handover occurs faster or more frequently than a metric adjusted according to another configuration. In this example, the selected configuration may be used when the network node has (at reference numeral 520) identified the coverage change as a coverage decrease, and another configuration may be used when no coverage decrease is identified or when an increase in coverage is identified.

[0094] As indicated by reference numeral 560, in some aspects, the UE and the network node may perform a handover to the cell indicated by the measurement report. For example, the network node (or a network entity associated with the network node) may trigger a handover of the UE from a serving cell associated with the network node to a neighboring cell (which may be associated with the network node or another network node). In some aspects, the network node (or a network entity associated with the network node) may reconfigure the neighboring cell to increase coverage of the neighboring cell (such as based at least in part on a coverage change identifying the serving cell). In some aspects, the network node may perform dynamic network antenna adaptation or dynamic beam adaptation as described with respect to reference numeral 520 (e.g., after a handover of the UE).

[0095] In this way, interruptions, latency, and unreliability of the UE's communications are reduced by, for example, triggering a handover before the coverage of a network node decreases due to dynamic antenna or beam adaptation.

[0096] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 Different than described.

[0097] Figure 6 6 is a diagram illustrating an example process 600 performed, for example, by a UE according to the present disclosure. Example process 600 is an example in which a UE (eg, UE 120) performs operations associated with mobility enhancement.

[0151] Fig. 9 The number and arrangement of components shown are provided as examples. In practice, there may be Fig. 9 The components shown may include additional components, fewer components, different components, or components arranged in a different manner. Fig. 9 Two or more components shown may be implemented in a single component, or Fig. 9 The single component shown may be implemented as multiple distributed components. Additionally or alternatively, Fig. 9 The illustrated set (one or more) of components may be described as being executable by Fig. 9 Another group of components shown performs one or more functions.

[0152] 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).

[0153] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack 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 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.

[0154] 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.

[0155] Fig.101 is a diagram illustrating an example decomposed base station architecture 1000 according to the present disclosure. The decomposed base station architecture 1000 may include a CU 1010, which may communicate directly with a core network 1020 via a backhaul link, or indirectly with the core network 1020 through one or more decomposed control units (such as a near-RT RIC 1025 via an E2 link, or a non-RT RIC 1015 associated with a service management and orchestration (SMO) framework 1005, or both). The CU 1010 may communicate with one or more DUs 1030 via respective midhaul links (such as via an F1 interface). Each of the DUs 1030 may communicate with one or more RUs 1040 via respective fronthaul links. Each of the RUs 1040 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 1040.

[0156] Each unit in the unit (including CU 1010, DU 1030, RU 1040) and near-RT RIC 1025, non-RTRIC 1015 and SMO framework 1005) may include one or more interfaces or be coupled to one or more interfaces, which are configured to receive or send signals, data or information (collectively referred to as signals) via a wired or wireless transmission medium. Each unit in the unit 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 units in the other units via a transmission medium. In some examples, each unit in the unit may include a wired interface and a wireless interface, the wired interface is configured to receive signals or send signals to one or more units in the other units through a wired transmission medium, and the wireless interface may include a receiver, a transmitter or a transceiver (such as an RF transceiver), which is configured to receive signals or send signals to one or more units in the other units through a wireless transmission medium or to perform both.

[0157] In some aspects, the CU 1010 may host one or more high-level control functions. Such control functions may include 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 1010. The CU 1010 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 1010 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 1010 may be implemented to communicate with the DU 1030 for network control and signaling.

[0158] Each DU 1030 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 1040. In some aspects, the DU 1030 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 10GPP. In some aspects, 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 1030 may also 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 1030 or with control functions hosted by the CU 1010.

[0159] Each RU 1040 may implement lower layer functionality. In some deployments, the RU 1040 controlled by the DU 1030 may correspond to a logical node that hosts RF processing functions or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. based on functional splitting (e.g., functional splitting defined by 10GPP) (such as lower layer functional splitting). In this architecture, each RU 1040 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 1040 may be controlled by the corresponding DU 1030. In some scenarios, this configuration may enable each DU 1030 and CU 1010 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0160] The SMO framework 1005 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 1005 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 1005 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 1090) 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 1010, DU 1030, RU 1040, non-RT RIC 1015, and near-RT RIC 1025. In some specific implementations, the SMO framework 1005 may communicate with hardware aspects of the 4G RAN, such as an open eNB (O-eNB) 1011, via the O1 interface. Additionally, in some implementations, the SMO framework 1005 can communicate directly with each of the one or more RUs 1040 via a corresponding O1 interface. The SMO framework 1005 can also include a non-RT RIC 1015 configured to support the functionality of the SMO framework 1005.

[0161] The non-RT RIC 1015 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 1025. The non-RT RIC 1015 may be coupled to or communicate with the near-RT RIC 1025 (such as via an A1 interface). The near-RT RIC 1025 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 1010, one or more DUs 1030, or both, and the O-eNB with the near-RT RIC 1025.

[0162] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 1025, the non-RT RIC 1015 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 1025 and may be received from a non-network data source or from a network function at the SMO framework 1005 or the non-RT RIC 1015. In some examples, the non-RT RIC 1015 or the near-RT RIC 1025 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 1015 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 1005 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).
