[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 485,171, filed on February 15, 2023, entitled “MEASUREMENT AND REPORTING FORSERVING AND CANDIDATE CELLS,” and U.S. Non-Provisional Patent Application No. 18 / 418,138, filed on January 19, 2024, entitled “MEASUREMENT AND REPORTING FORSERVING AND CANDIDATE CELLS,” which are 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 measurement and reporting of serving and candidate cells. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple access technologies capable of supporting 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 communication for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network node via downlink and uplink communications. A "downlink" (or "DL") refers to the communication link from the network node to the UE, and an "uplink" (or "UL") refers to the communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (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, regional, 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 better integrating with other open standards by using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink and 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; as well as 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

[0029] A cell may be both a serving cell and a candidate layer 1 (L1) or layer 2 (L2) (L1 / L2) triggered mobility (LTM) cell. For example, a cell may be a serving secondary cell (SCell) and a candidate LTM primary cell (PCell). Alternatively, a cell may be a serving PCell and a candidate LTM SCell. However, a user equipment (UE) associated with a cell may not be configured for measurements and reporting of the cell. In other words, when a cell is both a serving cell and a candidate LTM cell at the same time instance, measurements and reporting may not be configured to the UE for the cell. As a result, the UE may not be able to perform and report measurements for the cell, which may degrade the performance of the UE when an LTM cell handover is required (e.g., due to poor network conditions), but may not be triggered due to lack of measurements and reporting.

[0030] In some aspects, a UE may receive configurations of cells serving as serving cells and candidate LTM cells from a network node. The cell may be a serving PCell, and the candidate LTM cell may be a candidate LTM SCell. Alternatively, the cell may be a serving SCell, and the candidate LTM cell may be a candidate LTM PCell. The serving SCell may be activated or deactivated. The UE may receive measurement or reporting configurations for cells serving as serving cells and candidate LTM cells from the network node. In some cases, the UE may receive measurement and reporting configurations for cells serving as serving cells and candidate LTM cells. The UE may send measurement reports to the network node based at least in part on the measurement or reporting configurations. As a result, when a cell is both a serving cell and a candidate LTM cell, the UE may be able to perform and report measurements on the cell, which may improve the performance of the UE. The measurement and reporting of the cell may enable the network node to perform a cell handover for the UE, which may improve the performance of the UE. In other words, when the UE needs to handover to another cell to have favorable coverage, the network node may be able to initiate a cell handover because the network node receives measurements from the UE.

[0031] 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 construed as limited to any specific structure or function presented throughout the present disclosure. Rather, these aspects are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of protection of the present disclosure to those skilled in the art. It will be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether 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 an apparatus or practice method. Furthermore, the scope of the present disclosure is intended to cover such apparatus or methods implemented using other structures, functionality, or structures and functionality 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 present claims.

[0032] 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, or algorithms (collectively referred to as "elements"). These elements can 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.

[0033] Although various aspects may be described herein using terminology 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 post-5G (e.g., 6G) RATs.

[0034] Figure 1 1 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 (illustrated as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (illustrated 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, meaning 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 disaggregated network node (sometimes referred to as a disaggregated base station), meaning 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)).

[0035] In some examples, network node 110 is or includes a network node (such as an RU) that communicates with UE 120 via a radio access link. In some examples, network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link. In some examples, network node 110 (such as a converged 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. 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, an RU, a CU, a mobility element of a network, a core network node, a network element, 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 using any suitable transport network via various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0036] In some examples, 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 ​​network node 110 and / or a network node subsystem serving that coverage area, depending on the context in which the term is used. Network node 110 may provide communication coverage for a macrocell, a picocell, a femtocell, and / or another type of cell. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 120 with service subscriptions. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscriptions. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 associated with the femtocell (e.g., UEs 120 in a closed subscriber group (CSG)). A network node 110 for a macrocell may be referred to as a macro network node. A network node 110 for a picocell 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, 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, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0037] In some aspects, the term "base station" or "network node" may refer to a converged 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 multiple 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.

[0038] 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 can relay 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.

[0039] 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).

[0040] 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 these 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.

[0041] UEs 120 may be dispersed throughout 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 smartphone), 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 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, 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.

[0042] Some UEs 120 may be considered 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 Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. The UE 120 may be included within a housing that houses components of the 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, the processor component (e.g., one or more processors) and the memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0043] Generally speaking, 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. A RAT may be referred to as a radio technology, air interface, etc. A 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.

[0044] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) can 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 can 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 can perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0045] 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, 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). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the "sub-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 it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0046] 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 frequency 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 operation 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.

[0047] With the above examples in mind, unless otherwise specifically stated, it should be understood that if the term "sub-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. Furthermore, 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, 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.

[0048] In some aspects, a UE (e.g., UE 120) may include a communications manager 140. As described in greater detail elsewhere herein, the communications manager 140 may receive configurations of cells as serving cells and candidate LTM cells from a network node; receive measurement or reporting configurations for the cells as serving cells and candidate LTM cells from the network node; and send measurement reports to the network node based at least in part on the measurement or reporting configurations. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0049] In some aspects, a network node (e.g., network node 110) may include a communications manager 150. As described in greater detail elsewhere herein, the communications manager 150 may send a configuration of cells serving as serving cells and candidate LTM cells to a UE; send a measurement or reporting configuration for cells serving as serving cells and candidate LTM cells to the UE; and receive a measurement report from the UE based at least in part on the measurement or reporting configuration. Additionally or alternatively, the communications manager 150 may perform one or more other operations described herein.

[0050] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0051] 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 through 234t, such as T antennas (T ≥ 1). The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas (R ≥ 1). The network node 110 of example 200 includes one or more radio frequency components, such as antennas 234 and a modem 232. 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 radio frequency components, such as one or more CUs or one or more DUs, that facilitate direct communication with the UE 120.

[0052] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more modulation and coding schemes (MCS) for UE 120 based at least in part on one or more channel quality indicators (CQIs) received from UE 120. Network node 110 may process (e.g., encode and modulate) the data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols for UE 120. 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, as 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 through 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).

[0053] At the UE 120, a set of antennas 252 (shown as antennas 252a through 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 through 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 the 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, if 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 a 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, among other things, 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. In some examples, one or more components of the UE 120 may be included in a housing 284.

[0054] 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.

[0055] 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. The antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (within a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or 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.

[0056] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. 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, if applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted 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 execute the instructions herein (eg, reference Figures 8 to 12 ) any aspects of any of the methods described.

[0057] At network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., a demodulator component (shown as DEMOD) of modem 232), detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include a communication unit 244 and may communicate with network controller 130 via communication unit 244. Network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, modem 232 of network node 110 may include a modulator and a demodulator. In some examples, 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 herein (e.g., reference 242). Figures 8 to 12 ) any aspects of any of the methods described.

[0058] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with measurement and reporting for the serving cell and candidate cells, as described in more detail elsewhere herein. Figure 2 Any other component of the may perform or direct e.g. Figure 9 The process of 900 Figure 10 1000 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 (e.g., directly or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 9 The process of 900 Figure 10 The operations of process 1000 and / or other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, among others.

[0059] In some aspects, a UE (e.g., UE 120) includes means for receiving a configuration of cells as serving cells and candidate LTM cells from a network node; means for receiving a measurement or reporting configuration for cells as serving cells and candidate LTM cells from the network node; and / or means for sending a measurement report to the network node based at least in part on the measurement or reporting configuration. Means for the UE to perform the operations described herein may include, for example, one or more of the communications 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.

[0060] In some aspects, a network node (e.g., network node 110) includes: means for sending a configuration of cells as serving cells and candidate LTM cells to a UE; means for sending a measurement or reporting configuration for cells as serving cells and candidate LTM cells to the UE; and / or means for receiving a measurement report from the UE based at least in part on the measurement or reporting configuration. Means for the network node to perform the operations described herein may include, for example, one or more of the following: communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller / processor 240, memory 242, or scheduler 246.

[0061] Although Figure 2 The blocks in FIG. 2 are illustrated as distinct components, but the functionality described above with respect to 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.

[0062] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0063] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or constituent parts in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of the network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated architecture or a decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR base station, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) performing base station functionality can be implemented as an aggregated base station (also known as an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or a "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).

[0064] A converged base station (e.g., a converged network node) can 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) can 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, the 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 spread across one or more other network nodes. The DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and 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), among others.

[0065] Base station type operation or network design may take into account the aggregated nature of base station functionality. For example, a disaggregated 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 scaling of the communication system by separating base station functionality into one or more units that can be deployed separately. A disaggregated 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. Each unit of the disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0066] Figure 3 FIG2 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed 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 decomposed control units (such as a near-RT RIC 325 via an E2 link, 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.

[0067] Each of the units (including the CU 310, DU 330, RU 340) and the near-RT RIC 325, the non-RT RIC 315, and the SMO framework 305 may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, 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 the transmission medium. In some examples, each of the units may include a wired interface configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, and a wireless interface that may include a receiver, a transmitter, or a transceiver (such as an RF transceiver) configured to receive signals or transmit signals to one or more of the other units via a wireless transmission medium, or both.

[0068] 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, among others. 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 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.

[0069] 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 higher physical (PHY) layers, at least in part according to a functional split (such as that defined by 3GPP). In some aspects, the one or more higher PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and the like. In some aspects, the DU 330 may also host one or more lower PHY layers, such as those implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering. Each layer (which may also be referred to as a module) may be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0070] 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 such an architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some 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).

[0071] The SMO framework 305 can 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 can be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operations and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 can be configured to interact with a cloud computing platform (such as the 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 the 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-RT RIC 325. In some implementations, the SMO framework 305 can communicate with hardware aspects of the 4G RAN (such as 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.

[0072] 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 in communication with the near-RT RIC 325 (e.g., 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 through data collection and actions via an interface (e.g., 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.

[0073] In some implementations, to generate AI / ML models to be deployed in the near-RT RIC 325, the non-RT RIC 315 can receive parameters or external enrichment information from an external server. Such information can be utilized by the near-RT RIC 325 and can be received from non-network data sources or from network functions 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 can be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 can monitor long-term trends and patterns in performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or through the creation of RAN management policies (such as A1 interface policies).

[0074] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0075] Figure 4 is a diagram illustrating an example 400 of an LTM according to the present disclosure.

[0076] In LTM, the UE may be in an RRC connected state. As indicated by reference numeral 402, the UE may send a measurement report to the network node. The UE may send the measurement report via RRC signaling. The network node may determine to use LTM based at least in part on the measurement report and may initiate candidate LTM cell preparation. As indicated by reference numeral 404, the network node may send an RRC reconfiguration message to the UE. The RRC reconfiguration message may indicate a candidate LTM cell configuration, which may indicate a configuration of one or more candidate LTM target cells. The UE may store the candidate LTM cell configuration. As indicated by reference numeral 406, the UE may send an RRC reconfiguration complete message to the network node. The measurement report, the RRC reconfiguration message, and the RRC reconfiguration complete message may be part of the LTM preparation phase.

[0077] As indicated by reference numeral 408, the UE may perform downlink / uplink synchronization and timing advance (TA) acquisition with a candidate target cell, which may occur before receiving an LTM cell handover command. Downlink / uplink synchronization and TA acquisition may be associated with an early synchronization phase. The UE may perform L1 measurements on one or more configured candidate LTM target cells. As indicated by reference numeral 410, the UE may send an L1 measurement report to the network node, which may indicate L1 measurements on one or more configured candidate LTM target cells. The network node may determine to perform an LTM cell handover to the target cell, which may be based at least in part on the L1 measurement report. As indicated by reference numeral 412, the network node may send a MAC control element (MAC-CE) to the UE triggering an LTM cell handover, wherein the MAC-CE may indicate a candidate configuration index for the target cell. The UE may detach from the source cell. The UE may apply the candidate configuration index for the target cell. In other words, the UE may switch to the configuration of the candidate LTM target cell. As part of the LTM execution phase, the UE may detach from the source cell and attach to the target cell.

[0078] As indicated by reference numeral 414, the UE may perform a random access channel (RACH) procedure with the target cell (e.g., when the TA is not available). As indicated by reference numeral 416, the UE may send an indication to the target cell of the successful completion of the LTM cell handover to the target cell. The indication of the successful completion of the LTM cell handover may be part of the LTM completion phase.

[0079] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0080] Figure 5 is a diagram illustrating an example 500 of cell switching between L1 / L2 mobility candidate cells according to the present disclosure.

[0081] As shown by reference numeral 502, at a first point in time, the UE may be associated with a serving cell. The serving cell may or may not be associated with a serving cell group. The UE may perform measurements on one or more candidate cells. The candidate cells may or may not be associated with a candidate cell group. As shown by reference numeral 504, at a second point in time, the UE may be handed over to one of the candidate cells, which may become the serving cell, and the other cells may become candidate cells or remain candidate cells. As shown by reference numeral 506, at a third point in time, the UE may be handed over to one of the candidate cells, which may become the serving cell, and the other cells may become candidate cells or remain candidate cells.

[0082] In subsequent LTMs, the UE may perform cell switching between L1 / L2 mobility candidate cells (e.g., candidate LTM target cells). Cell switching between L1 / L2 mobility candidate cells may not involve RRC reconfiguration. In other words, sequential L1 / L2 cell changes between candidates may be supported without RRC reconfiguration. Cell switching without RRC reconfiguration may still involve downlink / uplink synchronization with the candidate target cell, L1 measurement reporting, cell switching commands (e.g., MAC-CE), and / or RACH procedures.

[0083] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0084] L1 / L2 mobility may include non-carrier aggregation scenarios (e.g., PCell only) and / or carrier aggregation scenarios (e.g., PCell and SCell). L1 / L2 mobility may involve situations where the target PCell and target SCell are not the current serving cell. Carrier aggregation scenarios may involve PCell changes. In some cases, L1 / L2 mobility may support carrier aggregation scenarios involving PCell changes without SCell changes, and / or carrier aggregation scenarios involving PCell changes with SCell changes. In some cases, in L1 / L2 mobility, the target PCell / SCell may be the current PCell / SCell. In other words, the current PCell / SCell may be configured as a candidate target cell. In addition, L1 / L2 mobility may be triggered based at least in part on L1 measurements.

[0085] Figure 6 is a diagram illustrating an example 600 of a cell as a serving cell or an LTM cell according to the present disclosure.

[0086] In the first scenario, a cell may be a serving cell or an LTM cell. By default, when a cell is a serving cell, a separate measurement and reporting configuration may be used compared to when the cell is an LTM cell.

[0087] As indicated by reference numeral 602, when a UE is served on a first cell (cell 1), the UE may perform L1 measurements and reporting of the first cell. The first cell may be the serving cell of the UE. When a second cell (cell 2) is configured as a candidate LTM cell, the UE may also perform L1 measurements and reporting of the second cell. The UE may perform channel state information (CSI) measurements and reporting of the first cell based at least in part on a CSI measurement configuration associated with the serving cell configuration of the first cell. The UE may follow the LTM-specific configuration for L1 measurements and reporting of the second cell, which may be a candidate LTM cell.

[0088] As indicated by reference numeral 604, after LTM execution, the second cell may become the serving cell, which may be measured and reported by the UE based at least in part on the corresponding new serving cell configuration. Where subsequent LTM is supported, the first cell may become a candidate LTM cell. The UE may follow the LTM-specific configuration for L1 measurements and reporting of the first cell.

[0089] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0090] Figure 7 is a diagram illustrating an example 700 of a cell that is both a serving cell and an LTM cell according to the present disclosure.

[0091] In the second scenario, the cell can be both a serving cell and an LTM cell. The target PCell / SCell can be the current PCell / SCell. In other words, the current PCell / SCell can be configured as a candidate LTM target cell.

[0092] As indicated by reference numeral 702, a UE may be associated with a primary first cell (P-Cell 1) and a secondary second cell (S-Cell 2). The primary second cell (P-Cell 2) may be a candidate LTM target cell. In other words, the second cell may be a serving SCell and a candidate LTM PCell, and the first cell may be a serving PCell. The network node may serve the first cell and the second cell, and in a first configuration, the second cell may be a serving SCell and a candidate LTM PCell, and the first cell may be a serving PCell.

[0093] As indicated by reference numeral 704, after LTM execution, the UE may be associated with a primary second cell (P-Cell2). The primary first cell (P-Cell1) and the secondary second cell (S-Cell2) may be candidate LTM target cells. In other words, the second cell may be a serving PCell and a candidate LTM SCell, and the first cell may be a candidate LTM PCell. The network node may serve the first cell and the second cell, and in a second configuration, the second cell may be a serving PCell and a candidate LTM SCell, and the first cell may be a candidate LTM PCell. The UE may perform a handover between the first configuration and the second configuration based at least in part on LTM execution.

[0094] In some cases, the cell may be both the serving PCell and the candidate LTM PCell. Alternatively, the cell may be both the serving SCell and the candidate LTM SCell.

[0095] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0096] A cell may be both a serving cell and a candidate LTM cell. For example, a cell may be a serving SCell and a candidate LTM PCell. Alternatively, a cell may be a serving PCell and a candidate LTM SCell. However, a UE associated with a cell may not be configured for L1 measurement and reporting of the cell. In other words, when a cell is both a serving cell and a candidate LTM cell at the same time instance, L1 measurement and reporting may not be configured to the UE for the cell. Furthermore, a mechanism for configuring the UE to perform L1 measurement and reporting of a cell and associated UE behavior may not be defined. As a result, the UE may not be able to perform L1 measurements for the cell and report L1 measurements for the cell, which may degrade the performance of the UE when LTM cell switching is required (e.g., due to poor network conditions), but may not be triggered due to lack of L1 measurement and reporting.

[0097] In various aspects of the techniques and apparatus described herein, a UE may receive a configuration of a cell as a serving cell and a candidate LTM cell from a network node. The cell may be a serving PCell, and the candidate LTM cell may be a candidate LTM PCell. Alternatively, the cell may be a serving SCell, and the candidate LTM cell may be a candidate LTM PCell. The serving SCell may be activated or deactivated. The UE may receive a measurement or reporting configuration for a cell as a serving cell and a candidate LTM cell from a network node. In some cases, the UE may receive a measurement and reporting configuration for a cell as a serving PCell and a candidate LTM SCell, or for a cell as a serving SCell and a candidate LTM PCell. The measurement and reporting configuration may be a single measurement and reporting configuration or multiple measurement and reporting configurations. The UE may send a measurement report to the network node based at least in part on the measurement or reporting configuration. As a result, when a cell is both a serving cell and a candidate LTM cell, the UE may be able to perform measurements on the cell and report measurements on the cell, which may improve the performance of the UE. Measurement and reporting on the cell may enable the network node to perform cell switching for the UE, which may improve the performance of the UE. In other words, when the UE needs to switch to another cell to have favorable coverage, the network node may be able to initiate a cell switch because the network node receives measurements from the UE.

[0098] Figure 8 8 is a diagram illustrating an example 800 associated with measurements and reporting for a serving cell and a candidate cell according to the present disclosure. Figure 8 As shown in , example 800 includes communications between a UE (e.g., UE 120) and a network node (e.g., network node 110). In some aspects, the UE and the network node may be included in a wireless network (such as wireless network 100).

[0099] As indicated by reference numeral 802, the UE may receive a configuration of a cell as a serving cell and a candidate LTM cell from a network node. The configuration may indicate that the cell is a serving PCell and the candidate LTM cell is a candidate LTM SCell. Alternatively, the configuration may indicate that the cell is a serving SCell and the candidate LTM cell is a candidate LTM PCell. The serving SCell may be an activated serving SCell or a deactivated serving SCell.

[0100] As indicated by reference numeral 804, the UE may receive measurement and / or reporting configurations for cells that are serving cells and candidate LTM cells from the network node. The measurement and / or reporting configurations may configure the UE to perform and / or report measurements associated with the cells.

[0101] In some aspects, the measurement and / or reporting configuration may be a single measurement and / or reporting configuration based at least in part on whether the cell is a serving PCell and a candidate LTM cell, or based at least in part on whether the cell is a serving SCell and a candidate LTM cell. The measurement and / or reporting configuration may be associated with the serving configuration of the cell, or the measurement and / or reporting configuration may be an LTM-specific configuration for the cell.

[0102] In some aspects, the UE may be a first UE. A measurement and / or reporting configuration associated with a serving configuration of a cell may be used for the first UE. A measurement and / or reporting configuration that is a LTM-specific configuration for the cell may be used for a second UE. In some aspects, the measurement and / or reporting configuration associated with the serving configuration of the cell may be used for the UE at a first time, and the measurement and / or reporting configuration that is a LTM-specific configuration for the cell may be used for the UE at a second time.

[0103] In some aspects, a cell may be a serving PCell and a candidate LTM SCell (or candidate LTM cell) (as previously indicated by reference numeral 704). For example, a UE may be associated with a primary second cell (P-Cell2), which may serve as a serving PCell. A secondary second cell (S-Cell2) may be a candidate LTM SCell. In this example, the second cell may be both a serving PCell and a candidate LTM SCell. The UE may perform measurements and reports on the second cell based at least in part on the second cell being a serving PCell and a candidate LTM SCell.

[0104] In some aspects, when a cell is both a serving PCell and a candidate LTM SCell, a network node may provide a single measurement and / or reporting configuration for the cell as both the serving PCell and the candidate LTM SCell. The single measurement and / or reporting configuration may be part of the serving configuration of the cell. Alternatively, the single measurement and / or reporting configuration may be an LTM-specific configuration for the cell. The UE may adhere to the single measurement and / or reporting configuration based at least in part on the cell being configured as both the serving PCell and the candidate LTM SCell.

[0105] In some aspects, a network node may use a single measurement and / or reporting configuration as part of a service configuration for one UE, and the network node may use a single measurement and / or reporting configuration as an LTM-specific configuration for another UE. In some aspects, a network node may use a single measurement and / or reporting configuration as part of a service configuration for a UE at one time, and the network node may use a single measurement and / or reporting configuration as part of an LTM-specific configuration for a UE at another time.

[0106] In some aspects, the measurement and / or reporting configuration may be two separate measurement and / or reporting configurations based at least in part on whether the cell is a serving PCell and a candidate LTM cell, or based at least in part on whether the cell is a serving SCell and a candidate LTM cell. A first measurement and / or reporting configuration of the two separate measurement and / or reporting configurations may be associated with the serving configuration of the cell. A second measurement and / or reporting configuration of the two separate measurement and / or reporting configurations may be an LTM-specific configuration of the cell.

[0107] In some aspects, the UE may activate one or more of the first measurement and / or reporting configuration or the second measurement and / or reporting configuration. The UE may send an indication to the network node that one or more of the first measurement and / or reporting configuration or the second measurement and / or reporting configuration is activated. In some aspects, the UE may receive an indication from the network node to activate one or more of the first measurement and / or reporting configuration or the second measurement and / or reporting configuration.

[0108] In some aspects, when the cell is a serving PCell and a candidate LTM SCell, the network node may provide separate measurement and / or reporting configurations for the cell as a serving PCell and a candidate LTM SCell. The first measurement and / or reporting configuration may be part of the serving configuration of the cell, and the second measurement and / or reporting configuration may be part of the LTM-specific configuration of the cell. The UE may activate both the first measurement and / or reporting configuration and the second measurement and / or reporting configuration. The UE may select and activate the first measurement and / or reporting configuration or the second measurement and / or reporting configuration, which may change over time based on changes in network conditions. The UE may indicate to the network node whether the first measurement and / or reporting configuration and / or the second measurement and / or reporting configuration is activated. In some aspects, the UE may receive an indication from the network node as to whether the first measurement and / or reporting configuration and / or the second measurement and / or reporting configuration should be activated by the UE. The indication may be received via RRC signaling, or the indication may be received in a more dynamic manner.

[0109] In some aspects, a cell may be a serving SCell and a candidate LTM PCell (or candidate LTM cell) (as previously indicated by reference numeral 702). For example, a UE may be associated with a primary first cell (P-Cell1) and a secondary second cell (SCell-2), the primary first cell may serve as a serving PCell. The primary second cell (P-Cell2) may be a candidate LTM PCell. In this example, the second cell may be both a serving SCell and a candidate LTM PCell. In some aspects, when a serving SCell (e.g., SCell-2) is activated, the UE may perform measurements and reports on the cell based at least in part on the cell being an activated serving SCell and a candidate LTM PCell. The serving SCell may be activated due to UE bandwidth requirements. In some aspects, when a serving SCell (e.g., SCell-2) is deactivated, the UE may cancel measurements and / or reporting on cells including the deactivated serving SCell, even if the cell is a candidate LTM PCell. Alternatively, the UE may still perform measurements on the cell for LTM purposes. For example, the UE can still measure the deactivated serving SCell (e.g., SCell-2) and candidate LTM PCell (e.g., SCell-2) for LTM purposes. The serving SCell may be deactivated due to UE bandwidth requirements. In contrast to the serving PCell, which can always be activated, the serving SCell can be activated or deactivated due to UE bandwidth requirements.

[0110] In some aspects, when a cell is both an activated serving SCell and a candidate LTM PCell, the network node may provide a single measurement and / or reporting configuration for the cell as both the activated serving SCell and the candidate LTM PCell. The single measurement and / or reporting configuration may be part of the cell's serving configuration. Alternatively, the single measurement and / or reporting configuration may be an LTM-specific configuration for the cell. The UE may adhere to the single measurement and / or reporting configuration based, at least in part, on the cell being configured as both the activated serving SCell and the candidate LTM PCell.

[0111] In some aspects, a network node may use a single measurement and / or reporting configuration as part of a service configuration for one UE, and the network node may use a single measurement and / or reporting configuration as an LTM-specific configuration for another UE. In some aspects, a network node may use a single measurement and / or reporting configuration as part of a service configuration for a UE at one time, and the network node may use a single measurement and / or reporting configuration as part of an LTM-specific configuration for a UE at another time.

[0112] In some aspects, when the cell is an activated serving SCell and a candidate LTM PCell, the network node may provide separate measurement and / or reporting configurations for the cell that is an activated serving SCell and a candidate LTM PCell. The first measurement and / or reporting configuration may be part of the serving configuration of the cell, and the second measurement and / or reporting configuration may be part of the LTM-specific configuration of the cell. The UE may activate both the first measurement and / or reporting configuration and the second measurement and / or reporting configuration. The UE may select and activate the first measurement and / or reporting configuration or the second measurement and / or reporting configuration, which may change over time based on changes in network conditions. The UE may indicate to the network node whether the first measurement and / or reporting configuration and / or the second measurement and / or reporting configuration is activated. In some aspects, the UE may receive an indication from the network node as to whether the first measurement and / or reporting configuration and / or the second measurement and / or reporting configuration should be activated by the UE. The indication may be received via RRC signaling, or the indication may be received in a more dynamic manner.

[0113] In some aspects, when the cell is a serving SCell and a candidate LTM cell, and when the serving SCell is a deactivated serving SCell, the UE may determine not to perform measurements and / or reports on the serving SCell based at least in part on the serving SCell being a deactivated serving SCell. Alternatively, the UE may determine to perform measurements and / or reports on the serving SCell based at least in part on the serving SCell being a deactivated serving SCell. In some aspects, the measurement and / or reporting configuration may be associated with the service configuration of the cell based at least in part on the serving SCell being deactivated. The measurement and / or reporting configuration may be an LTM-specific configuration based at least in part on the cell in which the serving SCell is deactivated. In addition, the measurement and / or reporting configuration may be based at least in part on the serving SCell being deactivated.

[0114] In some aspects, when a cell is both a deactivated serving SCell and a candidate LTM PCell, the UE may not perform measurements and / or reporting for the deactivated serving SCell, even when the cell is also a candidate LTM PCell. In this case, the UE may not send CSI measurement reports for the deactivated serving SCell. The serving SCell may need to be activated before LTM can be triggered, as no CSI measurement reports are available for the serving SCell.

[0115] In some aspects, when a cell is a deactivated serving SCell and a candidate LTM PCell, the UE may perform measurements and / or reporting of the deactivated serving SCell. The UE may perform measurements and / or reporting of the deactivated serving SCell using a configuration that is part of the service configuration of the cell. The UE may perform measurements and / or reporting of the deactivated serving SCell using the same configuration as when the serving SCell was activated. The configuration that is part of the service configuration of the cell may be associated with a single measurement and / or reporting configuration for the cell, or may be one of the separate measurement and / or reporting configurations for the cell. Alternatively, the UE may perform measurements and / or reporting of the deactivated serving SCell using an LTM-specific configuration for the cell. The LTM-specific configuration may be associated with a single measurement and / or reporting configuration for the cell, or may be one of the separate measurement and / or reporting configurations for the cell.

[0116] In some aspects, the UE may receive a measurement and / or reporting configuration from a network node that may be specific to measuring and / or reporting a serving SCell that is in a deactivated state. In other words, the measurement and / or reporting configuration may be used to measure and / or report a deactivated serving SCell. The measurement and / or reporting configuration may be associated with a single measurement and / or reporting configuration for a cell, or may be one of separate measurement and / or reporting configurations for a cell.

[0117] As indicated by reference numeral 806, the UE may send a measurement report to the network node based at least in part on the measurement or reporting configuration. The UE may send a measurement report for a cell that serves as a serving cell and a candidate LTM cell. For example, the UE may send a measurement report for a cell that serves as a serving PCell and a candidate LTM SCell. Alternatively, the UE may send a measurement report for a cell that serves as a serving SCell and a candidate LTM PCell, where the serving SCell may be an activated serving SCell or a deactivated serving SCell.

[0118] As indicated above, Figure 8 are provided as examples. Other examples can be found in the Figure 8 The examples described are different.

In some embodiments, the process 900 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted in FIG. Additionally or alternatively, two or more blocks of the blocks of process 900 may be executed in parallel.

[0140] Figure 10 is a diagram illustrating an example process 1000, performed, for example, by a network node, in accordance with the present disclosure.

The receiving component 1102 may provide the received communications to one or more other components of the apparatus 1100. In some aspects, the receiving component 1102 may perform signal processing (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding, etc.) on the received communications and may provide the processed signals to one or more other components of the apparatus 1100. In some aspects, the receiving component 1102 may include in conjunction with Figure 2 One or more antennas, modems, demodulators, MIMO detectors, receive processors, controllers / processors, memories, or combinations thereof of the described UE.

[0163] The transmitting component 1104 may transmit communications, such as reference signals, control information, data communications, or a combination thereof, to the apparatus 1108. In some aspects, one or more other components of the apparatus 1100 may generate communications and may provide the generated communications to the transmitting component 1104 for transmission to the apparatus 1108. In some aspects, the transmitting component 1104 may perform signal processing (such as filtering, amplification, modulation, digital-to-analog conversion, multiplexing, interleaving, mapping, or encoding, etc.) on the generated communications and may transmit the processed signals to the apparatus 1108. In some aspects, the transmitting component 1104 may include a combination of Figure 2 One or more antennas, modems, modulators, transmit MIMO processors, transmit processors, controllers / processors, memories, or combinations thereof of the described UE.

[0164] The communications manager 1106 can support the operation of the receiving component 1102 and / or the sending component 1104. For example, the communications manager 1106 can receive information associated with configuring the receipt of communications by the receiving component 1102 and / or the sending of communications by the sending component 1104. Additionally or alternatively, the communications manager 1106 can generate and / or provide control information to the receiving component 1102 and / or the sending component 1104 to control the receipt and / or sending of communications.

[0165] Receiving component 1102 can receive a configuration of a cell as a serving cell and a candidate LTM cell from a network node. Receiving component 1102 can receive a measurement or reporting configuration for the cell as a serving cell and a candidate LTM cell from the network node. Sending component 1104 can send a measurement report to the network node based at least in part on the measurement or reporting configuration.

[0166] The communication manager 1106 may activate one or more of the first measurement or reporting configuration or the second measurement or reporting configuration. The sending component 1104 may send an indication to the network node that one or more of the first measurement or reporting configuration or the second measurement or reporting configuration is activated. The receiving component 1102 may receive an indication from the network node to activate one or more of the first measurement or reporting configuration or the second measurement or reporting configuration. The communication manager 1106 may determine not to perform measurements or reports on the serving SCell based at least in part on the serving SCell being a deactivated serving SCell and the candidate LTM cell. The communication manager 1106 may determine to perform measurements or reports on the serving SCell based at least in part on the serving SCell being a deactivated serving SCell and the candidate LTM cell.
