[0002] This patent application claims priority to U.S. Provisional Patent Application No. 63 / 485,484, filed on February 16, 2023, entitled “REPORT CONFIGURATION FOR SERVING CELL AND CANDIDATE CELL,” and U.S. Non-Provisional Patent Application No. 18 / 440,138, filed on February 13, 2024, entitled “REPORT CONFIGURATION FOR SERVING CELL AND CANDIDATE CELL,” which are hereby expressly incorporated herein by reference and assigned to the assignee of this document. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for reporting configuration 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, region, and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) 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 to better integrate with other open standards; 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

[0030] 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 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 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 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 devices or methods implemented using other structures, functionality, or structure 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.

[0031] 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, "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.

[0032] 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.

[0033] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (illustrated as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple 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)).

[0034] 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.

[0035] 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 1 In 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).

[0036] 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.

[0037] 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 in , a network node 110 d (e.g., a relay network node) may communicate with a network node 110 a (e.g., a macro network node) and a UE 120 d to facilitate communications between the network node 110 a and the UE 120 d. 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.

[0038] 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).

[0039] 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.

[0040] 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.

[0041] 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 can 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.

[0042] 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.

[0043] 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.

[0044] The devices of the wireless network 100 may communicate using an electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency 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).

[0045] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz–24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and / or FR2 characteristics, thus effectively extending the features of FR1 and / or FR2 to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation to beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz–71 GHz), FR4 (52.6 GHz–114.25 GHz), and FR5 (114.25 GHz–300 GHz). Each of these higher frequency bands falls within the EHF band.

[0046] 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. Additionally, 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.

[0047] In some aspects, UE 120 may include a communications manager 140. As described in greater detail elsewhere herein, communications manager 140 may receive an updated serving cell configuration from a serving cell, the updated serving cell configuration including a reporting configuration associated with reporting measurements for a layer 1 or layer 2 triggered mobility (LTM) candidate cell; and send a measurement report to the serving cell via underlay transmission, the measurement report being based at least in part on the reporting configuration and including measurements for the LTM candidate cell. Additionally or alternatively, communications manager 140 may perform one or more other operations described herein.

[0048] In some aspects, a serving cell (e.g., a serving cell associated with network node 110) may include a communications manager 150. As described in greater detail elsewhere herein, communications manager 150 may send an updated serving cell configuration to a UE, the updated serving cell configuration including a reporting configuration associated with reporting measurements for an LTM candidate cell; and receive a measurement report from the UE via an underlay transmission, the measurement report being based at least in part on the reporting configuration and including measurements for the LTM candidate cell. Additionally or alternatively, communications manager 150 may perform one or more other operations described herein.

[0049] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0050] Figure 2 2 is a diagram illustrating 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 include radio frequency components, such as one or more CUs or one or more DUs, that facilitate direct communication with the UE 120.

[0051] At network node 110, transmit processor 220 may receive data intended for UE 120 (or a group 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. 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 frequency 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 (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a through 234t).

[0052] 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.

[0053] 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.

[0054] 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 groups of antenna elements, and / or one or more antenna arrays, etc. An antenna panel, antenna group, group of antenna elements, and / or antenna array may include one or more antenna elements (within a single housing or multiple housings), a group of coplanar antenna elements, a group 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.

[0055] 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 7 to 11 ) any aspects of any method described in the method.

[0056] 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 7 to 11 ) any aspects of any method described in the method.

[0057] 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 reporting configuration for serving cells and candidate cells, as described in more detail elsewhere herein. Figure 2 Any other component that can execute or guide e.g. Figure 8 The process of 800 Figure 9 900 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 8 The process of 800 Figure 9 The process 900 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0058] In some aspects, the UE includes means for receiving (e.g., using antenna 252, modem 254, MIMO detector 256, receive processor 258, controller / processor 280, memory 282, etc.) an updated serving cell configuration from the serving cell, the updated serving cell configuration including a reporting configuration associated with reporting measurements for an LTM candidate cell; and / or means for sending (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, modem 254, antenna 252, memory 282, etc.) a measurement report to the serving cell via underlay transmission, the measurement report being based at least in part on the reporting configuration and including measurements for the LTM candidate cell. Means for the UE to perform the operations described herein may include, for example, one or more of: 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.

[0059] In some aspects, the serving cell includes means for transmitting (e.g., using the controller / processor 240, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the memory 242, etc.) an updated serving cell configuration to the UE, the updated serving cell configuration including a reporting configuration associated with reporting measurements for the LTM candidate cell; and / or means for receiving (e.g., using the antenna 234, the modem 232, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, etc.) a measurement report from the UE via an underlay transmission, the measurement report being based at least in part on the reporting configuration and including measurements for the LTM candidate cell. In some aspects, means for the serving cell to perform the operations described herein may include, for example, one or more of: the communications manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0060] In some aspects, a single processor may perform all of the functions described as being performed by the one or more processors. In some aspects, the one or more processors may collectively perform a set of functions. For example, a first set of processors in the one or more processors (one or more processors) may perform a first function described as being performed by the one or more processors, and a second set of processors in the one or more processors (one or more processors) may perform a second function described as being performed by the one or more processors. The first set of processors and the second set of processors may be the same set of processors or may be different sets of processors. References to "one or more processors" should be understood to refer to the combination Figure 2 Any one or more of the processors described. References to "one or more memories" should be understood to refer to any one or more memories of the corresponding device, such as in conjunction with Figure 2 For example, functions described as being performed by one or more memories may be performed by the same subset of the one or more memories or by a different subset of the one or more memories.

[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) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually spread across one or more other network nodes. A 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 this 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 communicating with the control plane and user plane of 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 both non-virtualized 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 can 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 the 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 can be configured to include logic that enables 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 can be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 can be configured to include logic that enables near-real-time control and optimization of RAN elements and resources through data collection and actions over an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0073] In some implementations, the non-RT RIC 315 can receive parameters or external enrichment information from an external server in order to generate an AI / ML model to be deployed in the near-RT RIC 325. 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 4 is a diagram illustrating an example 400 of physical channels and reference signals in a wireless network according to the present disclosure. Figure 4 As shown in , the downlink channel and the downlink reference signal may carry information from the network node 110 to the UE 120 , and the uplink channel and the uplink reference signal may carry information from the UE 120 to the network node 110 .

[0076] As shown, downlink channels may include, among others, a physical downlink control channel (PDCCH) carrying downlink control information (DCI), a physical downlink shared channel (PDSCH) carrying downlink data, or a physical broadcast channel (PBCH) carrying system information. In some aspects, PDSCH communications may be scheduled by PDCCH communications. As further shown, uplink channels may include, among others, a physical uplink control channel (PUCCH) carrying uplink control information (UCI), a physical uplink shared channel (PUSCH) carrying uplink data, or a physical random access channel (PRACH) for initial network access. In some aspects, UE 120 may send acknowledgement (ACK) or negative acknowledgement (NACK) feedback (e.g., ACK / NACK feedback or ACK / NACK information) in the UCI on the PUCCH and / or PUSCH.

[0077] As further shown in the figure, the downlink reference signal may include a synchronization signal block (SSB), a channel state information (CSI) reference signal (CSI-RS), a demodulation reference signal (DMRS), a positioning reference signal (PRS), or a phase tracking reference signal (PTRS), etc. As also shown in the figure, the uplink reference signal may include a sounding reference signal (SRS), a DMRS, or a PTRS, etc.

[0078] The SSB may carry information used for initial network acquisition and synchronization, such as the Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), PBCH, and PBCH DMRS. The SSB is sometimes referred to as a Synchronization Signal / PBCH (SS / PBCH) block. In some aspects, the network node 110 may transmit multiple SSBs on multiple corresponding beams, and the SSBs may be used for beam selection.

[0079] The CSI-RS may carry information for downlink channel estimation (e.g., downlink CSI acquisition), which may be used for scheduling, link adaptation, or beam management, among other things. The network node 110 may configure a CSI-RS set for the UE 120, and the UE 120 may measure the configured CSI-RS set. Based at least in part on these measurements, the UE 120 may perform channel estimation and may report channel estimation parameters such as a channel quality indicator (CQI), a precoding matrix indicator (PMI), a CSI-RS resource indicator (CRI), a layer indicator (LI), a rank indicator (RI), or a reference signal received power (RSRP) to the network node 110 (e.g., in a CSI report). The network node 110 may use the CSI reports to select transmission parameters for downlink communications to the UE 120, such as the number of transmission layers (e.g., rank), a precoding matrix (e.g., a precoder), a modulation and coding scheme (MCS), or to refine the downlink beam (e.g., using a beam refinement process or a beam management process), among others.

[0080] DMRS can carry information used to estimate the radio channel to demodulate the associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH, or PUSCH). The design and mapping of DMRS can be specific to the physical channel that the DMRS is used to estimate. DMRS is UE-specific, can be beamformed, can be restricted to scheduled resources (e.g., rather than being sent over a wideband), and can be sent only when necessary. As shown in the figure, DMRS is used for both downlink and uplink communications.

[0081] PTRS can carry information used to compensate for oscillator phase noise. Typically, phase noise increases with increasing oscillator carrier frequency. Therefore, PTRS can be used at high carrier frequencies (such as millimeter wave frequencies) to mitigate phase noise. PTRS can be used to track the phase of the local oscillator and to achieve phase noise and common phase error (CPE) suppression. As shown in the figure, PTRS is used for both downlink communications (e.g., on the PDSCH) and uplink communications (e.g., on the PUSCH).

[0082] The PRS may carry information used to implement timing or ranging measurements of the UE 120 based on signals transmitted by the network node 110 to improve observed time difference of arrival (OTDOA) positioning performance. For example, the PRS may be a pseudo-random quadrature phase shift keying (QPSK) sequence mapped in a diagonal pattern with a frequency offset and a time offset to avoid collisions with cell-specific reference signals and control channels (e.g., PDCCH). Generally speaking, the PRS may be designed to improve detectability for the UE 120, which may need to detect downlink signals from multiple neighboring network nodes in order to perform OTDOA-based positioning. Thus, the UE 120 may receive PRS from multiple cells (e.g., a reference cell and one or more neighboring cells) and may report reference signal time difference (RSTD) based on OTDOA measurements associated with the PRS received from the multiple cells. In some aspects, the network node 110 may then calculate the position of the UE 120 based on the RSTD measurements reported by the UE 120.

[0083] The SRS may carry information used for uplink channel estimation, which may be used for scheduling, link adaptation, precoder selection, or beam management, among other things. Network node 110 may configure one or more SRS resource sets for UE 120, and UE 120 may transmit the SRS on the configured SRS resource sets. The SRS resource sets may have configured uses such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operation, uplink beam management, and so on. Network node 110 may measure the SRS, perform channel estimation based at least in part on these measurements, and use the SRS measurements to configure communications with UE 120.

[0084] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0085] Figure 5 5 is a diagram illustrating an example 500 of layer 1 (L1) or layer 2 (L2) triggered mobility (LTM) according to the present disclosure. UE 120 may communicate with network node 110. In some cases, network node 110 may be a base station, such as a gNB.

[0086] As shown at 505, UE 120 may transmit a MeasurementReport message to network node 110. The MeasurementReport message is based on the previous serving cell configuration and reporting configuration. Therefore, it should be understood that before 505, network node 110 sent the previous serving cell configuration and the previous reporting configuration. In response to the MeasurementReport message, network node 110 decides to use LTM and initiates LTM candidate preparation.

[0087] As indicated by reference numeral 510 , the network node 110 sends an RRCReconfiguration message to the UE 120 including configuration of one or more LTM candidate target cells.

[0088] As indicated by reference numeral 515 , the UE 120 stores the configuration of the LTM candidate target cell and sends an RRCReconfigurationComplete message to the network node 110 .

[0089] As indicated by reference numeral 520, the UE 120 may perform downlink (DL) synchronization and timing advance (TA) acquisition with a candidate target cell before receiving the LTM cell handover command.

[0090] As indicated by reference numeral 525 , the UE 120 performs L1 measurement on the configured LTM candidate target cell and sends a layer measurement report to the network node 110 .

[0091] As indicated by reference numeral 530, the network node 110 determines to perform LTM cell handover to the target cell and transmits a MAC control element (MAC-CE) triggering LTM cell handover by including the candidate configuration index of the target cell. The UE 120 switches to the configuration of the LTM candidate target cell.

[0092] As indicated by reference numeral 535, if the TA is not available, the UE 120 performs a random access procedure toward the target cell.

[0093] As shown at reference numeral 540, the UE 120 indicates successful completion of the LTM cell handover towards the target cell.

[0094] In some cases, RAN2 (e.g., RAN2#119bis-e protocol) indicates that sequential L1 / L2 cell changes between candidates can be supported without RRC reconfiguration. However, for a single RRC configuration, the serving cell and candidate cells can change after each LTM execution.

[0095] As indicated above, Figure 5are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0096] Figure 6 is a diagram illustrating an example 600 of measurement reporting according to the present disclosure.

[0097] The UE measures the serving cell and submits a report on the same, as indicated by reference numeral 605. The CSI resource configuration and the CSI reporting configuration are part of the serving cell configuration of the serving cell.

[0098] As shown in reference numeral 610, the UE measures serving cell 1 and submits a report to serving cell 2. This can be applied, for example, to carrier aggregation. The CSI resource configuration of cell 1 is part of the serving cell configuration of serving cell 1. The CSI reporting configuration of cell 1 is part of the serving cell configuration of serving cell 2. The reports from cell 1 and cell 2 to cell 2 can be separate.

[0099] As shown in the reference numeral 615, the UE measures the cell associated with the additional physical cell identity (PCI) and submits the report to the serving cell. This can be applied to, for example, mTRP. The CSI resource configuration of the additional PCI is part of the SSB measurement timing configuration (SMTC) in MeasObjectNR. The CSI resource configuration of the serving cell includes a pointer to the SMTC of the additional PCI. The CSI report configuration of the serving cell includes a pointer to the CSI resource configuration of the serving cell. Reporting of the serving cell PCI and the additional PCI can be combined.

[0100] As shown in reference numeral 620, the UE performs L1 measurements of the LTM candidate cells and reports these measurements to the serving cell. This can be applied, for example, in an LTM scenario.

[0101] In some cases, the UE may need to transmit a report for the serving cell and one or more candidate cells in a single reporting instance, which report includes intra-frequency measurements and / or inter-frequency measurements. In some cases, the reporting configuration will be included in the configuration of the serving cell, and the resource configuration may be included in, for example, the configuration of the serving cell, the configuration of the candidate cell, or may be external to the configuration of the serving cell and the configuration of the candidate cell. In some cases, the UE may not be able to determine which reporting configuration to use. For example, the UE may not be able to determine which reporting configuration should be used to meet the requirement that the UE will transmit a report for the serving cell and one or more candidate cells in a single reporting instance, which report includes intra-frequency measurements and / or inter-frequency measurements. This may result in measurements for the candidate cell not being correctly reported to the serving cell, which may result in interruptions in the handover process, etc.

[0102] Techniques and apparatus for reporting configuration of serving cells and candidate cells are described herein. In some aspects, a UE may receive an updated serving cell configuration from a serving cell, the updated serving cell configuration including a reporting configuration associated with reporting measurements for an LTM candidate cell. The UE may send a measurement report to the serving cell via underlying transmission, the measurement report being based at least in part on the reporting configuration and including measurements for the LTM candidate cell. Thus, the UE may accurately report measurements for the serving cell and one or more candidate cells in a single reporting instance. Additional details are described herein.

[0103] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0104] Figure 7 is a diagram illustrating an example 700 of a reporting configuration for a serving cell and a candidate cell according to the present disclosure. A UE 120 may communicate with a serving cell 705, e.g., to report measurement information associated with the serving cell 705 and / or an LTM candidate cell 710. In some aspects, the serving cell 705 may be associated with a first DU 330, and the LTM candidate cell 710 may be associated with a second DU 330. In some other aspects, the serving cell 705 and the LTM candidate cell may be associated with the same DU 330. In some aspects, the network node may receive the reporting configuration from a CU 310.

[0105] As indicated by reference numeral 715, serving cell 705 may transmit an updated serving cell configuration, and UE 120 may receive the updated serving cell configuration, which includes a reporting configuration associated with reporting measurements for LTM candidate cells. Although not illustrated, it should be understood that, prior to transmitting the updated serving cell configuration, the serving cell transmits a previous serving cell configuration including a previous reporting configuration. Communications and measurement reporting prior to reference numeral 715 are performed based on the previous serving cell configuration and the previous reporting configuration. Thus, the updated serving cell configuration corresponds to an update of the previous serving cell configuration, and similarly, the updated serving cell configuration corresponds to an update of the previous reporting configuration. In some aspects, the difference between the updated serving cell configuration and the previous serving cell configuration is the updated reporting configuration, while in other aspects, other aspects of the serving cell configuration are also updated.

[0106] As indicated by reference numeral 720, UE 120 may transmit a measurement report, and serving cell 705 may receive the measurement report, based at least in part on the reporting configuration and including measurements for the LTM candidate cell. The measurement report may be transmitted by UE 120 using a lower layer transmission, such as an L1 transmission, an L2 transmission, or a layer 3 (L3) transmission.

[0107] In some aspects, the CSI reporting configuration of the LTM candidate cell 710 will be part of the serving cell configuration (e.g., ServingCellConfig) of the serving cell 705. At least one serving cell configuration of the current serving cell group will include a reporting configuration for each LTM candidate cell 710 (to be measured).

[0108] In some aspects, the measurement report may be a measurement report associated with the serving cell 705 and / or the LTM candidate cell 710. For example, the measurement report may be for only the serving cell 705, only the LTM candidate cell 710, or both the serving cell 705 and the LTM candidate cell 710.

[0109] In a first option, one reporting configuration may exclusively point to (eg, indicate) a CSI resource configuration associated with the CSI resources of the LTM candidate cell 710 .

[0110] In a second example, one reporting configuration may point to a CSI resource configuration associated with a combination of CSI resources of the serving cell 705 and the LTM candidate cell 710 .

[0111] In a third example, one reporting configuration may point to multiple CSI resource configurations, where one CSI resource configuration is associated with the CSI resources of the serving cell 705 and another CSI resource configuration is associated with the CSI resources of the LTM candidate cell 710 .

[0112] In some aspects, the first option may allow separate CSI reporting of the serving cell 705 and the LTM candidate cell 710. In some aspects, the second and third examples may allow combined reporting of the serving cell 705 and the LTM candidate cell 710.

[0113] In some aspects, the first option may be used for SSB-based reporting, CSI-RS-based reporting, or a combination of SSB-based reporting and CSI-RS-based reporting. In some aspects, the second and third options may allow for SSB-based reporting for the serving cell 705 and / or the LTM candidate cell 710, CSI-RS-based reporting for the serving cell 705 and / or the LTM candidate cell 710, or a combination of SSB-based reporting and CSI-RS-based reporting for the serving cell 705 and / or the LTM candidate cell 710.

[0114] An example solution for the configuration of SSB-based reports is shown below:

[0115]

[0116]

[0117] The CSI-ReportConfig includes resourcesForChannelMeasurement for the serving cell and a separate resourcesForChannelMeasurement for the LTM or LTM candidate, with an indication of the cell and potentially the location of the configuration. This can use a separate CSI-ReportConfig with a pointer to the CSI-ReportConfig of the serving cell.

[0118] CSI-ResourceConfig includes a csi-SSB-ResourceSetList for the serving cell and another csi-SSB-ResourceSetList for LTM or LTM candidates, and has a corresponding indication of the cell.

[0119] In the csi-SSB-ResourceSetList, each CSI-SSB-ResourceSet may correspond to a serving cell or an LTM or a (LTM candidate) cell and have a corresponding indication of the cell.

[0120] The CSI-SSB-ResourceSet may include one csi-SSB-ResourceList for the serving cell and another csi-SSB-ResourceList for the LTM (or LTM candidate) cell, with corresponding indications of the cells (potentially with corresponding AdditionalPCIList).

[0121] In csi-SSB-ResourceList, each SSB index may correspond to a serving cell, an additional PCI, or an LTM cell, and have a corresponding indication of the cell.

[0122] In some aspects, the SMTC and frequency information may already be provided in the serving cell configuration of the LTM candidate cell 710, or a pointer may be included. The UE 120 may perform early decoding of the configuration of the LTM cell to obtain this information. This operation may be performed if the CSI-ResourceConfig for the LTM candidate cell 710 is included in the serving cell configuration of the cell. Alternatively, separate SMTC and / or frequency information may be provided outside the serving cell configuration of the LTM candidate cell 710 (e.g., within or outside the serving cell configuration of the serving cell 705). In some aspects, the indication of the LTM candidate cell 710 in the above example may provide a pointer to the SMTC and / or frequency information.

[0123] An example solution for the configuration of CSI-RS based reporting is shown below:

[0124]

[0125] The CSI-ReportConfig includes resourcesForChannelMeasurement for the serving cell and a separate resourcesForChannelMeasurement for LTM or LTM candidate, with an indication of the cell and potentially the location of the CSI-Resource config for the latter. This can use a separate CSI-ReportConfig with a pointer to the CSI-ReportConfig of the serving cell.

[0126] CSI-ResourceConfig includes a non-zero power (NZP) CSI-RS resource set list (nzp-CSI-RS-ResourceSetList) for the serving cell and another nzp-CSI-RS-ResourceSetList for the LTM (or LTM candidate) cell, and has corresponding indications for the cells.

[0127] In the nzp-CSI-RS-ResourceSetList, each NZP-CSI-RS-ResourceSet may correspond to a serving cell or an LTM (or LTM candidate) cell and have a corresponding indication of the cell.

[0128] The NZP-CSI-RS-ResourceSet may include one nzp-CSI-RS-Resources for the serving cell and another nzp-CSI-RS-Resources for the LTM (or LTM candidate) cell, with corresponding indications of the cells.

[0129] In nzp-CSI-RS-Resources, each NZP-CSI-RS-ResourceId may correspond to a serving cell or an LTM cell and have a corresponding indication of the cell.

[0130] In some aspects, CSI-ReportConfigs associated with LTM cells can be provided as part of the configuration of multiple serving cells to enable reporting on multiple serving cells. Alternatively, reporting can be restricted to the serving PCell. In some aspects, a reporting configuration can be associated with resources corresponding to one or more LTM cells. A UE can be dynamically queried to submit reports for a subset of resources corresponding to a specific reporting configuration to allow dynamic measurements of LTM cells, thereby minimizing overhead.

[0131] In some aspects, the UE is configured with multiple LTM candidate cells, the multiple LTM candidate cells including at least the LTM candidate cell and another LTM candidate cell. In some aspects, the reporting configuration is associated with one or more measurement resources for the serving cell and for one of the LTM candidate cell or the another LTM candidate cell. In some aspects, the reporting configuration is associated with one or more measurement resources for the serving cell, the LTM candidate cell, and the another LTM candidate cell. In some aspects, the reporting configuration includes a first reporting configuration associated with one or more measurement resources for the serving cell and a second reporting configuration associated with one or more measurement resources for the LTM candidate cell or the another LTM candidate cell. In some aspects, the reporting configuration includes a first reporting configuration associated with one or more measurement resources for the serving cell, a second reporting configuration associated with one or more measurement resources for the LTM candidate cell, and a third reporting configuration associated with one or more resources for the another LTM candidate cell.

[0132] In some aspects, the UE is configured with multiple serving cells, the multiple serving cells including at least the serving cell and another serving cell. In some aspects, the LTM candidate cell is configured to be reported on the serving cell, and the another LTM candidate cell is configured to be reported on the another serving cell. In some aspects, the LTM candidate cell and the another LTM candidate cell are configured to be reported on the serving cell, wherein reporting on the serving cell uses a first reporting configuration, and reporting on the another serving cell uses a second reporting configuration.

[0133] In some aspects, the first reporting configuration associated with the serving cell may be the same as a previous reporting configuration associated with the serving cell, or may also be updated, and the second reporting configuration may be new compared to the previous reporting configuration prior to the updated serving cell configuration. In some aspects, the third reporting configuration may be new compared to the previous reporting configuration.

[0134] In some aspects, a UE may receive an LTM candidate cell configuration that includes a reporting configuration associated with reporting measurements for the serving cell. The UE may apply the reporting configuration associated with reporting measurements for the serving cell after performing LTM operations and establishing a connection to the LTM candidate cell. In some aspects, the reporting configuration associated with reporting measurements for the serving cell includes a reporting configuration associated with reporting measurements for another LTM candidate cell. In some aspects, the UE may apply the reporting configuration associated with reporting measurements for the another LTM candidate cell based at least in part on performing LTM operations and establishing a connection to the LTM candidate cell.

[0135] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0136] Figure 8 is a diagram illustrating an example process 800, performed, for example, by a UE, in accordance with the present disclosure.
