Abstract

Various aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may receive downlink control information (DCI) from a network node via an active cell associated with the network node that triggers layer 1 (L1) measurement reporting. The UE may transmit the L1 measurement report to the network node via the active cell based at least in part on the DCI, the L1 measurement report indicating inter-frequency L1 measurements associated with a candidate cell associated with the network node, the candidate cell and the active cell being associated with different frequencies, and channel state information (CSI) processing times associated with the inter-frequency L1 measurements are based, at least in part, on mobility based on L1 or layer 2 (L2) (L1 / L2). Numerous other aspects are described.

Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for channel state information (CSI) processing time for inter-frequency measurements associated with candidate cells. Background Art

[0002] 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).

[0003] 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.).

[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region, and / or global level. New Radio (NR) (which may be referred to as 5G) is 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

[0025] 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 the scope of protection 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 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 method that is practiced 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.

[0026] 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.

[0027] 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.

[0028] 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)).

[0029] 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.

[0030] 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).

[0031] 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 a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to 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.

[0032] 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.

[0033] 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).

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] The devices of the wireless network 100 can communicate using an electromagnetic spectrum, which can be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, the devices of the wireless network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that although portions of FR1 are 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).

[0040] 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.

[0041] 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.

[0042] 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 downlink control information (DCI) triggering a layer 1 (L1) measurement report from a network node via an active cell associated with the network node; and send the L1 measurement report to the network node via the active cell based at least in part on the DCI, the L1 measurement report indicating an inter-frequency L1 measurement associated with a candidate cell associated with the network node, the candidate cell and the active cell being associated with different frequencies, and a channel state information (CSI) processing time associated with the inter-frequency L1 measurement being based at least in part on L1 or layer 2 (L2) (L1 / L2)-based mobility. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0043] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may: send a DCI triggering an L1 measurement report to a UE via an active cell associated with the network node; and receive an L1 measurement report from the UE via the active cell based at least in part on the DCI, the L1 measurement report indicating an inter-frequency L1 measurement associated with a candidate cell associated with the network node, the candidate cell and the active cell being associated with different frequencies, and a CSI processing time associated with the inter-frequency L1 measurement being based at least in part on L1 / L2-based mobility. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0044] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0045] 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 not include radio frequency components, such as one or more CUs or one or more DUs, that facilitate direct communication with the UE 120.

[0046] 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).

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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 6 to 12 ) any aspects of any of the methods described.

[0051] 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 decoded data to a data sink 239 and 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 6 to 12 ) any aspects of any of the methods described.

[0052] 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 CSI processing time for inter-frequency measurements associated with 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 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.

[0053] In some aspects, a UE (e.g., UE 120) includes: means for receiving a DCI triggering an L1 measurement report from a network node via an active cell associated with the network node; and / or means for sending an L1 measurement report to the network node via the active cell based at least in part on the DCI, the L1 measurement report indicating an inter-frequency L1 measurement associated with a candidate cell associated with the network node, the candidate cell and the active cell being associated with different frequencies, and a CSI processing time associated with the inter-frequency L1 measurement being based at least in part on L1 / L2-based mobility. Means for the UE to perform the operations described herein may include, for example, one or more of the following: the communications manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0054] In some aspects, a network node (e.g., network node 110) includes means for sending a DCI triggering an L1 measurement report to a UE via an active cell associated with the network node; and / or means for receiving an L1 measurement report from the UE via the active cell based at least in part on the DCI, the L1 measurement report indicating an inter-frequency L1 measurement associated with a candidate cell associated with the network node, the candidate cell and the active cell being associated with different frequencies, and a CSI processing time associated with the inter-frequency L1 measurement being based at least in part on L1 / L2-based mobility. Means for the network node to perform the operations described herein may include, for example, one or more of the following: the communication 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.

[0055] 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.

[0056] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0057] The deployment of a communication system such as a 5G NR system can be arranged in a variety of ways with various components or constituent parts. 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 may 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 may be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. 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).

[0058] 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 CUs, DUs, and RUs 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.

[0059] 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. Various units of the disaggregated base station may be configured for wired or wireless communication with at least one other unit of the disaggregated base station.

[0060] 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.

[0061] 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.

[0062] 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 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 divided 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.

[0063] 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.

[0064] Each RU 340 may implement low-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 low-layer functional split), such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0065] The SMO framework 305 can be configured to support RAN deployment and configuration 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-RTRIC 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.

[0066] 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.

[0067] In some implementations, the non-RT RIC 315 may 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 may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to regulate RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns 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).

[0068] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0069] Figure 4 is a diagram illustrating an example 400 of a special cell (SpCell) change based on L1 measurement according to the present disclosure.

[0070] like Figure 4 As shown in, in L1 / L2-based mobility, the SpCell can be updated via L1 / L2 signaling based at least in part on L1 measurements. The L1 measurements can be intra-frequency measurements and / or inter-frequency measurements. The UE can perform a single SpCell change without carrier aggregation (CA). The UE can be connected to an old SpCell (e.g., an initial cell). The old SpCell can be a first SpCell. The UE can perform L1 measurements associated with a candidate SpCell. The candidate SpCell can be associated with a preconfigured set of candidate SpCells. The UE can report the L1 measurements to the network node. Based on the L1 measurements, the UE can switch from the old SpCell to a new SpCell, which can be one of the candidate SpCells. The new SpCell can be a second SpCell. L1 / L2-based mobility can involve handover of the UE from the old SpCell to the new SpCell.

[0071] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0072] An L1 / L2-based inter-cell mobility procedure may be defined to achieve mobility delay reduction. An L1 / L2-based inter-cell mobility procedure may involve configuration and maintenance for multiple candidate cells to allow relatively quick application of the configuration for the candidate cells. An L1 / L2-based inter-cell mobility procedure may define a dynamic switching mechanism between candidate serving cells (including SpCells and serving cells (SCells)), which is based at least in part on L1 / L2 signaling for potential applicable scenarios. An L1 / L2-based inter-cell mobility procedure may define L1 enhancements for inter-cell beam management, which includes L1 measurement and reporting and beam indication. An L1 / L2-based inter-cell mobility procedure may define timing advance (TA) management. An L1 / L2-based inter-cell mobility procedure may define CU-DU interface signaling to support L1 / L2-based mobility. The L1 / L2-based inter-cell mobility procedure is applicable to standalone scenarios, CA scenarios, or NR dual connectivity (NR-DC) scenarios, where the serving cell change is performed within a configured grant (CG). The L1 / L2-based inter-cell mobility procedure is applicable to intra-DU scenarios and / or intra-CU inter-DU scenarios. The L1 / L2-based inter-cell mobility procedure is applicable to both intra-frequency and inter-frequency. The L1 / L2-based inter-cell mobility procedure is applicable to both FR1 and FR2. The L1 / L2-based inter-cell mobility procedure is applicable to source and target cells, which can be synchronized or asynchronous.

[0073] Figure 5 is a diagram illustrating an example 500 of L1 measurements for L1 / L2 based mobility according to the present disclosure.

[0074] like Figure 5 As shown in , the UE may be configured with an active SpCell. The active SpCell may send DCI to the UE, which may trigger L1 measurements and reports for the candidate SpCell. The active SpCell and the candidate SpCell may be associated with a network node. The UE may receive DCI from the active SpCell. The DCI may trigger measurements of synchronization signal blocks (SSBs) or channel state information reference signals (CSI-RSs) associated with the candidate SpCell. The candidate SpCell may send SSBs / CSI-RSs. The UE may receive and measure SSBs / CSI-RSs that may be based at least in part on the DCI. The UE may generate an L1 measurement report that may be based at least in part on measurements associated with the SSBs / CSI-RSs. The UE may send an L1 measurement report to the active SpCell via a physical uplink shared channel (PUSCH).

[0075] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0076] L1 inter-frequency measurements may be supported for L1 / L2-based mobility. For example, an old cell (e.g., an initial cell) and a candidate cell may be associated with different frequencies, so measurements associated with the old cell and the candidate cell may be inter-frequency measurements. For candidate cell measurements for L1 / L2-based mobility or lower layer triggered mobility (LTM), SSB-based L1-RSRP may be supported for intra-frequency measurements, and SSB-based L1-RSRP may be supported for inter-frequency measurements. In addition, L1 signal to interference plus noise ratio (SINR) (L1-SINR) and CSI-RS-based L1-RSRP may be supported for inter-frequency / intra-frequency measurements.

[0077] Regarding the CSI processing timeline in NR, when the CSI request field on the DCI triggers a CSI report on the PUSCH, the UE may provide a valid CSI report for the nth triggered report. When the first uplink symbol used to carry the corresponding CSI report includes the effect of TA, the CSI report may be sent no earlier than symbol Z. ref When the first uplink symbol used to carry the nth CSI report includes the effect of TA, the CSI report may be no earlier than symbol Z' ref (n) Start. In addition, Z ref It can be defined as the period of time after the end of the last symbol of the physical downlink control channel (PDCCH) that triggers the CSI report. proc,CSI =(Z)(2048+144)·κ2 -μ ·T C +T switch The next uplink symbol starting from which Z, κ, μ, T C and T switch It is further defined in 3GPP Technical Specification (TS) 38.214 Section 5.4 (Release 17). In addition, Z' ref (n) can be defined as the time T′ after the end of the last symbol of the latest term among the following proc,CSI =(Z′)(2048+144)·κ2 -μ ·T CNext uplink symbol starting from: when aperiodic CSI-RS is used for channel measurement for the nth triggered CSI report, aperiodic CSI-RS resources for channel measurement, aperiodic channel state information interference management (CSI-IM) resources for interference measurement, and aperiodic non-zero power (NZP) CSI-RS resources for interference measurement, and where T switch Thus, the first processing timeline may be associated with DCI indicated via PDCCH and CSI reporting, and the second processing timeline may be associated with measurement resources and CSI reporting.

[0078] Inter-frequency L1 measurements may be supported for L1 / L2-based mobility. A UE may need to switch between frequencies to perform inter-frequency L1 measurements on a candidate cell. A legacy CSI processing timeline may be defined for legacy L1 measurements. However, the legacy CSI processing timeline may not be applicable to inter-frequency L1 measurements. The legacy CSI processing timeline may not account for UEs switching between frequencies to perform inter-frequency L1 measurements on a candidate cell. Therefore, a new CSI processing timeline may need to be defined for inter-frequency L1 measurements for L1 / L2-based mobility.

[0079] In various aspects of the techniques and apparatus described herein, a UE may receive a DCI triggering an L1 measurement report from a network node via an active cell associated with the network node (e.g., an active SpCell). The UE may receive an SSB or CSI-RS from the network node via a candidate cell associated with the network node (e.g., a candidate SpCell). The candidate cell and the active cell may be associated with different frequencies. The UE may perform inter-frequency L1 measurements on the SSB or CSI-RS. The inter-frequency L1 measurement may be associated with a handover of the UE from the active cell to the candidate cell. The UE may send an L1 measurement report to the network node via the active cell based at least in part on the DCI. The L1 measurement report may indicate an inter-frequency L1 measurement. The CSI processing time associated with the inter-frequency L1 measurement may be based at least in part on L1 / L2-based mobility. The CSI processing time may be sufficient for the UE to process the inter-frequency L1 measurement, thereby improving the performance of the UE.

[0080] Figure 6 6 is a diagram illustrating an example 600 associated with CSI processing time for inter-frequency measurements associated with a candidate cell according to the present disclosure. Figure 6 As shown, example 600 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).

[0081] As shown by reference numeral 602, the UE may receive a DCI triggering an L1 measurement report from the network node via an active cell associated with the network node. The UE may receive the DCI via a physical downlink control channel (PDCCH). The active cell may be an active SpCell. The L1 measurement report may be associated with a candidate cell. The candidate cell may be a candidate SpCell. The candidate cell may be associated with a preconfigured set of candidate cells. The active cell and the candidate cell may be associated with different frequencies. In some other aspects, the UE may receive a medium access control element (MAC-CE) or RRC signaling triggering the L1 measurement report from the network node via the active cell associated with the network node.

[0082] As shown by reference numeral 604, the UE may send an L1 measurement report to the network node via the active cell based at least in part on the DCI. The UE may send the L1 measurement report via a physical uplink control channel (PUCCH). The L1 measurement report may indicate an inter-frequency L1 measurement associated with a candidate cell associated with the network node. The inter-frequency L1 measurement may be an SSB-based L1-RSRP measurement or a CSI-RS-based L1-RSRP measurement. The CSI processing time associated with the inter-frequency L1 measurement may be based at least in part on L1 / L2-based mobility.

[0083] In some aspects, the CSI processing time may be a first processing time between the end of the last symbol of the PDCCH carrying the DCI and the first symbol of the PUSCH carrying the L1 measurement report. The CSI processing time may be based at least in part on a switching time (T m,switch ), and the first CSI processing parameter associated with L1 / L2-based mobility (Z m The switching time associated with L1 / L2-based mobility may be a switching time defined for a candidate cell associated with L1 / L2-based mobility, or may be a legacy switching time (T switch ) plus the switching time offset (ΔT switch ). The switching time offset and / or the switching time defined for the candidate cell associated with L1 / L2-based mobility may be based at least in part on the UE capabilities. The first CSI processing parameter associated with L1 / L2-based mobility may be a parameter dedicated to inter-frequency L1 measurements for L1 / L2-based mobility, or may be a legacy CSI processing parameter (Z) plus an increment parameter (ΔZ) for additional processing delay due to inter-frequency L1 measurements for L1 / L2-based mobility.

[0084] In some aspects, the CSI processing time may be a second processing time between one of: an end of a last symbol in time associated with a measurement resource (e.g., an SSB / CSI-RS measurement resource) and a first symbol of a PUSCH carrying an L1 measurement report, an end of a synchronization signal block (SSB) measurement timing configuration (SMTC) window and a first symbol of a PUSCH carrying an L1 measurement report, or an end of a measurement gap and a first symbol of a PUSCH carrying an L1 measurement report. The CSI processing time may be based at least in part on a second CSI processing parameter (Z′) associated with L1 / L2-based mobility. m The second CSI processing parameter associated with L1 / L2-based mobility may be a parameter dedicated to inter-frequency L1 measurement for L1 / L2-based mobility, or may be a legacy CSI processing parameter (Z) plus an increment parameter (ΔZ) for additional processing delay due to inter-frequency L1 measurement for L1 / L2-based mobility.

[0085] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The examples described are different.

[0086] In some aspects, new CSI processing timing may be defined for candidate cells for L1 / L2 based mobility. In L1 / L2 based mobility, a UE may be configured to report L1 measurements on resources associated with a candidate cell (such as SSB / CSI-RS resources), where new switching time requirements may be defined for corresponding CSI reporting. In a first option, the new switching time T for mobility may be m,switch It can be defined as follows:

[0087]

[0088] Where T switch is the switching time associated with the active cell (eg, source cell), and T m,switch is the switching time associated with the candidate cell (e.g., target cell). When the UE uses the switching time for the active cell, the switching time may be the same as T switch Correspondingly, when the UE uses the switching time for the candidate cell, the switching time can be m,switch The switching time requirements for the active cell and the candidate cell may be different. In the second option, the new switching time offset ΔT switch It can be defined as follows: T m,switch =T switch +ΔT switch. The switching time for candidate cells (T m,switch ) can be achieved through T switch +ΔT switch To calculate, where T m,switch and / or ΔT switch It may be based at least in part on UE capabilities.In other words, the switching time for the candidate cell may be smaller or larger than the switching time for the active cell, depending on the new switching time offset.

[0089] Figure 7 is a diagram illustrating an example 700 associated with CSI processing time for inter-frequency measurements associated with a candidate cell according to the present disclosure.

[0090] In some aspects, in L1 / L2 based mobility, the UE may be configured to report L1 measurements on resources associated with a candidate cell (such as SSB / CSI-RS resources) with a new minimum time offset requirement (Z m ) can be defined between the end of the last symbol of the PDCCH that triggers the CSI report and the first symbol of the CSI report. The new minimum time offset requirement Z m It can be compared with the CSI processing time (T proc,CSI ), where the CSI processing time can be between the DCI associated with the PDCCH and the CSI report. In the first option, Z m It can be a new parameter dedicated to L1 measurement in L1 / L2 based mobility. In the second option, Z m According to Z m = Z + ΔZ, where Z is the legacy CSI processing parameter and ΔZ is a new parameter for the additional processing delay associated with L1 measurements in L1 / L2 based mobility. In addition, the CSI processing time can be calculated based on T proc,CSI =(Z m )(2048+144)·κ2 -μ ·T C +T m,switch To define, where Z m It is a mobility related parameter and is associated with the time between DCI and CSI reporting.

[0091] like Figure 7As shown in , the UE may be configured with an active SpCell. The active SpCell may send DCI to the UE, which may trigger L1 measurements and reporting for the candidate SpCell. The candidate SpCell may be associated with a different frequency than the active SpCell. In other words, the candidate SpCell and the active SpCell may be associated with different frequencies. The active SpCell and the candidate SpCell may be associated with a network node. The UE may receive DCI from the active SpCell. The DCI may trigger measurement of SSB / CSI-RS associated with the candidate SpCell. The candidate SpCell may send SSB / CSI-RS. The UE may receive and measure the SSB / CSI-RS which may be based at least in part on the DCI. The measurements associated with the SSB / CSI-RS may be inter-frequency measurements because the active SpCell and the candidate SpCell may be associated with different frequencies, and the UE may need to switch to the frequency associated with the candidate SpCell in order to measure the SSB / CSI-RS. The UE may generate an L1 measurement report that may be based at least in part on measurements associated with the SSB / CSI-RS. The UE may send the L1 measurement report to the active SpCell via the PUSCH. The CSI processing time (T) between the DCI triggering the L1 measurement and report and the PUSCH with the L1 report is proc,CsI )According to: T proc,CSl =(Z m )(2048+144)·κ2 -μ ·T C +T m,switch , where T proc,CSI can correspond to the number of symbols, and where Z m are new parameters dedicated to L1 measurements in L1 / L2 based mobility, or are new parameters based at least in part on legacy CSI processing parameters and for additional processing delay for L1 measurements in L1 / L2 based mobility.

[0092] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.

[0093] In some aspects, when the CSI request field on the DCI triggers a CSI report on the PUSCH for a candidate cell configured for mobility (e.g., a candidate cell associated with a handover), the UE may provide a valid CSI report for the nth triggered report. When the first uplink symbol used to carry the corresponding CSI report includes the effect of the TA, the CSI report may be sent no earlier than symbol Z. ref Start with Z refis defined as the CP T after the end of the last symbol of the PDCCH that triggers the CSI report proc,CSI =(Z m )(2048+144)·κ2 -μ ·T C +T m,switch For candidate cells configured for mobility, Z m and T m,switch There may be newly defined mobility related parameters that may be used for handover.

[0094] Figure 8 is a diagram illustrating an example 800 associated with CSI processing time for inter-frequency measurements associated with a candidate cell according to the present disclosure.

In the first option, the CSI processing time can be between the end of the last symbol in time of the most recently measured resource (e.g., SSB / CSI-RS resource) and the first symbol of the CSI report. In the second option, the CSI processing time can be between the end of the SMTC window and the first symbol of the CSI report. In the third option, the CSI processing time can be between the end of the measurement gap and the first symbol of the CSI report.

[0096] In some aspects, Z′ m It can be a new parameter dedicated to L1 measurement in L1 / L2 based mobility. m According to Z′ m = Z' + ΔZ', where Z' is the legacy CSI processing parameter and ΔZ' is a new parameter for the additional processing delay associated with L1 measurements in L1 / L2 based mobility. proc,CSI ) can be defined according to the following formula: proc,CSI =(Z′ m )(2048+144)·κ2 -μ ·T C , where Z′ mis a mobility-related parameter and is associated with a time between a measurement-related time instance (eg, based at least in part on the first option, the second option, or the third option) and a CSI report.

[0097] like Figure 8 As shown in , the UE may be configured with an active SpCell. The active SpCell may send DCI to the UE, which may trigger L1 measurement and reporting for the candidate SpCell. The candidate SpCell may be associated with a different frequency than the active SpCell. In other words, the candidate SpCell and the active SpCell may be associated with different frequencies. The active SpCell and the candidate SpCell may be associated with a network node. The UE may receive DCI from the active SpCell. The DCI may trigger measurement of the SSB / CSI-RS associated with the candidate SpCell. The candidate SpCell may send SSB / CSI-RS. The UE may receive and measure the SSB / CSI-RS which may be based at least in part on the DCI. The measurement associated with the SSB-CSI-RS may be an inter-frequency measurement because the active SpCell and the candidate SpCell may be associated with different frequencies, and the UE may need to switch to the frequency associated with the candidate SpCell in order to measure the SSB / CSI-RS. The UE may generate an L1 measurement report, which may be based at least in part on measurements associated with the SSB / CSI-RS.The UE may send the L1 measurement report to the active SpCell via the PUSCH.

[0098] In some aspects, such as Figure 8 As shown in , the CSI processing time (T proc,CSI ) may correspond to the time between the end of the last symbol in time of the most recently measured resource (e.g., SSB / CSI-RS resource) and the first symbol of the CSI report (e.g., Option 3), the CSI processing time may correspond to the time between the end of the SMTC window and the first symbol of the CSI report (e.g., Option 2), or the CSI processing timeline may correspond to the time between the end of the measurement gap and the first symbol of the CSI report (e.g., Option 1). For Option 3, Option 2, or Option 1, the CSI processing time may be defined as follows: T′ proc,CSI =(Z′ m )(2048+144)·κ2 -μ ·T C , where T proc,CSI can correspond to the number of symbols, and where Z′ mare new parameters dedicated to L1 measurements in L1 / L2 based mobility, or are new parameters based at least in part on legacy CSI processing parameters and for additional processing delay for L1 measurements in L1 / L2 based mobility.

[0099] As indicated above, Figure 8 are provided as examples. Other examples can be found in the Figure 8 The examples described are different.

[0100] In some aspects, when the CSI request field on the DCI triggers a CSI report on the PUSCH for a candidate cell configured for mobility (e.g., a candidate cell associated with a handover), the UE may provide a valid CSI report for the nth triggered report. When the first uplink symbol used to carry the nth CSI report includes the effect of the TA, the CSI report may be sent no earlier than symbol Z' ref Start with Z' ref is defined as the time T′ after the end of the last symbol of the latest term whose CP is proc,CSI =(Z′ m )(2048+144)·κ2 -μ ·T C Next uplink symbol starting: When aperiodic CSI-RS is available for channel measurement for the nth triggered CSI report, after the end of the SMTC, or after the end of the measurement gap, aperiodic CSI-RS resources for channel measurement, aperiodic CSI-IM resources for interference measurement, or aperiodic NZP CSI-RS for interference measurement. For candidate cells configured for mobility, Z′ m There may be newly defined mobility related parameters that may be used for handover.
