Description

Technical Field

[0001] This application relates to wireless communication, and more specifically to systems, apparatus, and methods for measuring neighboring cells in wireless communication systems. Background Technology

[0002] The use of wireless communication systems is growing rapidly. In recent years, wireless devices such as smartphones and tablets have become increasingly sophisticated. In addition to supporting phone calls, many mobile devices (i.e., user equipment or UE) now offer access to the internet, email, text messaging, and navigation using the Global Positioning System (GPS), and are capable of operating complex applications that utilize these capabilities. Furthermore, many different wireless communication technologies and standards exist. Some examples of wireless communication standards include GSM, UMTS (e.g., associated with WCDMA or TD-SCDMA air interfaces), LTE, LTE-A (LTE-Advanced), NR, HSPA, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), IEEE 802.11 (WLAN or Wi-Fi), and BLUETOOTH. TM wait.

[0003] The introduction of an ever-increasing number of features and functions into wireless communication devices necessitates continuous improvement of both wireless communication and the devices themselves. Ensuring the accuracy of signals transmitted and received by user equipment (UE) devices (e.g., wireless devices such as cellular phones, base stations, and relay stations used in wireless cellular communications) is of paramount importance. Furthermore, increasing the functionality of UE devices can significantly strain their battery life. Therefore, it is equally crucial to reduce the power requirements in UE device design while allowing them to maintain good transmission and reception capabilities for improved communication. Thus, improvements are expected in this area. Summary of the Invention

[0004] This document provides apparatus, systems, and methods for neighboring cell measurements in wireless communication systems. Such neighboring cell measurements may be or include inter-frequency layer 1 (L1) measurements.

[0005] The UE can establish a radio link with the serving cell. The serving cell can provide configuration information to the UE, and the UE can receive this configuration information. Based on this configuration information, the UE can determine a first measurement period for performing inter-frequency Layer 1 (L1) measurements on a first neighboring cell (or multiple neighboring cells). The UE can receive at least one reference signal from the first neighboring cell (or multiple cells). This reference signal can be CSI-RS, SSB, etc. The UE can perform at least one L1 measurement of the at least one reference signal according to the first measurement period for performing inter-frequency L1 measurements on the first neighboring cell. Among various possibilities, this measurement can be L1-SINR and / or L1-RSRP. The UE can transmit a report of the at least one L1 measurement to the serving cell.

[0051] the term

[0052] The following is a glossary of terms that will appear in this disclosure:

[0053] Memory media—any device of any type of nontransitory memory device or storage device. The term "memory media" is intended to include mounting media such as CD-ROMs, floppy disks, or magnetic tape devices; computer system memory or random access memory such as DRAM, DDR RAM, SRAM, EDO RAM, Rambus RAM, etc.; non-volatile memory such as flash memory, magnetic media, e.g., hard disk drives or optical storage devices; registers or other similar types of memory elements, etc. Memory media may also include other types of nontransitory memory or combinations thereof. Furthermore, memory media may reside in a first computer system executing a program, or may reside in a different second computer system connected to the first computer system via a network such as the Internet. In a later example, the second computer system may provide program instructions to the first computer system for execution. The term "memory media" may include two or more memory media that may reside in different locations on different computer systems connected via a network, for example. Memory media may store program instructions (e.g., representing a computer program) that can be executed by one or more processors.

[0054] Carrier medium—the memory medium as described above, and physical transmission medium, such as buses, networks and / or other physical transmission media for transmitting signals (such as electrical signals, electromagnetic signals or digital signals).

[0055] Computer system (or computer) — any of the various types of computing or processing systems, including personal computer systems (PCs), mainframe computer systems, workstations, network appliances, internet-connected appliances, personal digital assistants (PDAs), television systems, grid computing systems, or other devices or combinations thereof. Generally, the term "computer system" can be broadly defined as any device (or combination of devices) that includes at least one processor that executes instructions from a memory medium.

[0056] User equipment (UE) (or “UE device”) — any of various types of computer systems or devices that are mobile or portable and perform wireless communication. Examples of UE devices include mobile phones or smartphones (e.g., iPhone). TM Based on Android TM Phones), tablets (e.g., iPads) TM Samsung Galaxy TM ), portable gaming devices (e.g., Nintendo DS) TM PlayStation Portable TM Gameboy Advance TM iPhone TMThis includes wearable devices (e.g., smartwatches, smart glasses), laptops, PDAs, portable internet devices, music players, data storage devices, other handheld devices, automobiles and / or motor vehicles, unmanned aerial vehicles (UAVs) (e.g., drones), UAV controllers (UACs), etc. Generally speaking, the term "UE" or "UE device" can be broadly defined to encompass any electronic device, computing device, and / or telecommunications device (or a combination of these devices) that is easily transportable by the user and capable of wireless communication.

[0057] A wireless device is any of various types of computer systems or devices that perform wireless communication. A wireless device can be portable (or mobile), or it can be stationary or fixed in a location. A UE is an example of a wireless device.

[0058] A communication device is any of various types of computer systems or devices that perform communication, which may be wired or wireless. A communication device may be portable (or mobile), or it may be stationary or fixed in a location. A wireless device is one example of a communication device. A UE is another example of a communication device.

[0059] Base station (BS) — The term “base station” has the full range of its usual meaning and includes at least a wireless communication station that is installed in a fixed location and used for communication as part of a wireless telephone system or radio system.

[0060] A processing element (or processor) is a component or combination of components capable of performing the functions of a device (such as a user equipment device or a cellular network device). A processing element may include, for example: a processor and associated memory, portions or circuitry of individual processor cores, an entire processor core, a processor array, circuitry such as an ASIC (Application-Specific Integrated Circuit), programmable hardware components such as a Field-Programmable Gate Array (FPGA), and any combination thereof.

[0061] Wi-Fi—The term “Wi-Fi” encompasses the full range of its common meaning and includes at least wireless communication networks, or RATs, which are provided by and through wireless LAN (WLAN) access points to provide connectivity to the Internet. Most modern Wi-Fi networks (or WLAN networks) are based on the IEEE 802.11 standard and are marketed under the name “Wi-Fi.” Wi-Fi (WLAN) networks are distinct from cellular networks.

[0062] Automatic—means an action or operation performed by a computer system (e.g., software executed by the computer system) or device (e.g., circuits, programmable hardware elements, ASICs, etc.) without requiring direct user input to specify or perform that action or operation. Therefore, the term "automatic" contrasts with an action performed or specified manually by a user, where the user provides input to directly perform that action. An automatic process can be initiated by user-provided input, but the subsequent actions performed "automatically" are not specified by the user; that is, they are not performed "manually," where the user specifies each action to be performed. For example, a user filling out a form by selecting each field and providing input to specify information (e.g., by typing information, selecting a checkbox, radio selection, etc.) is considered manually filling out the form, even though the computer system must update the form in response to the user's actions. The form can be automatically filled out by a computer system (e.g., software executed on the computer system) which analyzes the fields of the form and fills it out without any user input specifying answers for the fields. As indicated above, the user can invoke the automatic filling of the form but does not participate in the actual filling of the form (e.g., the user does not manually specify answers for the fields, but they are completed automatically). This manual provides various examples of operations that are automatically performed in response to actions taken by the user.

[0063] "Configured as"—Various components can be described as being "configured as" to perform one or more tasks. In such contexts, "configured as" is a broad expression generally meaning "having" a "structure" that performs one or more tasks during operation. Thus, a component can be configured to perform a task even when it is not currently performing one (e.g., a set of electrical conductors can be configured to electrically connect one module to another, even when the two modules are not connected). In some contexts, "configured as" can also be a broad expression generally meaning a structure that "has" a "circuit" that performs one or more tasks during operation. Thus, a component can be configured to perform a task even when it is not currently powered on. Typically, the circuit forming the structure corresponding to "configured as" can include hardware circuitry.

[0064] For ease of description, various components may be described as performing one or more tasks. Such descriptions shall be interpreted as including the phrase “configured to”. The statement that a component is configured to perform one or more tasks is expressly intended not to invoke the interpretation of paragraph 6 of section 112 of title 35 of the United States Code.

[0065] Figure 1 and Figure 2 -Exemplary communication system

[0066] Figure 1 Exemplary (and simplified) wireless communication systems that can implement various aspects of this disclosure according to some embodiments are shown. It should be noted that... Figure 1The system described is merely one example of a possible system, and this implementation can be carried out in any of a variety of systems as needed.

[0067] As shown in the figure, this exemplary wireless communication system includes a base station 102 that communicates with one or more (e.g., any number) user equipments 106A, 106B, etc., up to 106N, via a transmission medium. Each user equipment may be referred to herein as a "user equipment" (UE) or UE device. Therefore, user equipment 106 is referred to as a UE or UE device.

[0068] Base station 102 may be a transceiver base station (BTS) or a cell site, and may include hardware and / or software for enabling wireless communication with UEs 106A to 106N. If base station 102 is implemented in an LTE environment, it may be referred to as an "eNodeB" or "eNB". If base station 102 is implemented in a 5G NR environment, it may alternatively be referred to as a "gNodeB" or "gNB". Base station 102 may also be equipped to communicate with network 100 (e.g., the core network of a cellular service provider, telecommunications networks such as the Public Switched Telephone Network (PSTN), and / or the Internet, and various other possible networks). Therefore, base station 102 facilitates communication between user equipments and / or between user equipments and network 100. The communication area (or coverage area) of a base station may be referred to as a "cell". Also as used herein, in relation to a UE, a base station may sometimes be considered to represent the network, taking into account both uplink and downlink communication of the UE. Therefore, a UE communicating with one or more base stations in the network may also be understood as a UE communicating with the network.

[0069] Base station 102 and user equipment can be configured to communicate via a transmission medium using any of a variety of radio access technologies (RATs), also known as wireless communication technologies or telecommunications standards, such as GSM, UMTS (WCDMA), LTE, LTE-A Advanced, LAA / LTE-U, 5G NR, 3GPP2, CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), Wi-Fi, etc.

[0070] Base station 102 and other similar base stations operating according to the same or different cellular communication standards may thus provide, as one or more cell networks, continuous or near-continuous overlapping services to UE 106 and similar devices over a geographic area via one or more cellular communication standards.

[0071] It should be noted that UE 106 can communicate using multiple wireless communication standards. For example, UE 106 can be configured to communicate using either or both of the 3GPP cellular communication standards or the 3GPP2 cellular communication standards. In some implementations, UE 106 can be configured to perform neighbor cell measurements in a wireless communication system based on techniques that combine neighbor cell measurements to align the expected behavior of the wireless device and the cellular network, such as the various methods described herein. UE 106 can also be configured, or alternatively configured, to use WLAN, BLUETOOTH, etc. TM It can communicate with one or more Global Navigation Satellite Systems (GNSS, such as GPS or GLONASS), one and / or more mobile television broadcasting standards (e.g., ATSC-M / H), etc. Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.

[0072] Figure 2 An exemplary user equipment 106 (e.g., one of devices 106A to 106N) communicating with base station 102 according to some embodiments is illustrated. UE 106 can be a device with wireless network connectivity, such as a mobile phone, handheld device, wearable device, computer or tablet, unmanned aerial vehicle (UAV), unmanned flight controller (UAC), automobile, or virtually any type of wireless device. UE 106 may include a processor (processing element) configured to execute program instructions stored in memory. UE 106 can perform any of the method embodiments of the present invention by executing such stored instructions. Alternatively or additionally, UE 106 may include programmable hardware elements, such as any of an FPGA (Field Programmable Gate Array), integrated circuit, and / or various other possible hardware components configured to perform (e.g., individually or in combination) any of or any portion of any of the method embodiments described herein. UE 106 may be configured to communicate using any of a plurality of wireless communication protocols. For example, UE 106 can be configured to communicate using two or more of CDMA2000, LTE, LTE-A, 5G NR, WLAN, or GNSS. Other combinations of wireless communication standards are also possible.

[0073] UE 106 may include one or more antennas communicating using one or more wireless communication protocols according to one or more RAT standards. In some embodiments, UE 106 may share one or more portions of the receive chain and / or transmit chain among multiple wireless communication standards. The shared radio components may include a single antenna, or may include multiple antennas for performing wireless communication (e.g., for MIMO). Typically, the radio components may include any combination of baseband processors, analog radio frequency (RF) signal processing circuitry (e.g., including filters, mixers, oscillators, amplifiers, etc.), or digital processing circuitry (e.g., for digital modulation and other digital processing). Similarly, the radio components may use the aforementioned hardware to implement one or more receive chains and transmit chains.

[0074] In some implementations, UE 106 may include separate transmit and / or receive chains (e.g., including separate antennas and other radio components) for each wireless communication protocol configured to communicate therewith. As another possibility, UE 106 may include one or more radio components shared among multiple wireless communication protocols, as well as one or more radio components uniquely used by a single wireless communication protocol. For example, UE 106 may include shared radio components for communication using either LTE or CDMA2000 1xRTT (or LTE or GSM), and for communication using Wi-Fi and BLUETOOTH. TM Each component communicates independently. Other configurations are also possible.

[0075] Figure 3 - Block diagram of an exemplary UE device

[0076] Figure 3A block diagram of an exemplary UE 106 according to some embodiments is shown. As shown, UE 106 may include a System-on-Chip (SOC) 300, which may include parts for various purposes. For example, as shown, SOC 300 may include a processor 302 capable of executing program instructions for UE 106, and display circuitry 304 capable of performing graphics processing and providing display signals to a display 360. SOC 300 may also include sensor circuitry 370, which may include components for sensing or measuring any of a variety of possible characteristics or parameters of UE 106. For example, sensor circuitry 370 may include motion sensing circuitry configured to detect motion of UE 106, for example, using a gyroscope, accelerometer, and / or any of a variety of other motion sensing components. As another possibility, sensor circuitry 370 may include one or more temperature sensing components, for example, for measuring the temperature of each of one or more antenna panels and / or other components of UE 106. Any of a variety of other possible types of sensor circuitry may also or alternatively be included in UE 106 as needed. Processor 302 may also be coupled to memory management unit (MMU) 340, which may be configured to receive addresses from processor 302 and translate those addresses into locations in memory (e.g., memory 306, read-only memory (ROM) 350, NAND flash memory 310) and / or other circuitry or devices, such as display circuitry 304, radio components 330, connector I / F 320, and / or display 360. MMU 340 may be configured to perform memory protection and page table translation or setup. In some embodiments, MMU 340 may be included as part of processor 302.

[0077] As shown in the figure, the SOC 300 can be coupled to various other circuits of the UE 106. For example, the UE 106 may include various types of memory (e.g., including NAND flash memory 310), connector interface 320 (e.g., for coupling to computer systems, docking stations, charging stations, etc.), display 360, and wireless communication circuitry 330 (e.g., for LTE, LTE-A, NR, CDMA2000, BLUETOOTH). TM(e.g., Wi-Fi, GPS, etc.). UE device 106 may include at least one antenna (e.g., 335a) and may include multiple antennas (e.g., shown by antennas 335a and 335b) for performing wireless communication with base stations and / or other devices. Antennas 335a and 335b are shown by way of example, and UE device 106 may include fewer or more antennas. In general, one or more antennas are collectively referred to as antenna 335. For example, UE device 106 may use antenna 335 to perform wireless communication via radio circuitry 330. As described above, in some embodiments, the UE may be configured to use multiple wireless communication standards for wireless communication.

[0078] UE 106 may include hardware and software components for implementing methods for performing neighboring cell measurements in a wireless communication system, such as those described further herein, based on techniques for aligning the expectations and behaviors of wireless devices and cellular networks using neighboring cell measurements. The processor 302 of UE device 106 may be configured to implement some or all of the methods described herein, for example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium). In other embodiments, processor 302 may be configured as a programmable hardware element, such as an FPGA (Field-Programmable Gate Array) or as an ASIC (Application-Specific Integrated Circuit). Furthermore, processor 302 may be coupled to, for example,... Figure 3 Other components shown and / or interoperable with other components are used to perform neighbor cell measurements in a wireless communication system according to techniques for aligning the desired behavior of wireless devices and cellular networks, based on various embodiments disclosed herein. Processor 302 may also implement various other applications and / or end-user applications running on UE 106.

[0079] In some implementations, radio component 330 may include a separate controller dedicated to controlling communications for various corresponding RAT standards. For example, such as Figure 3 As shown, the radio component 330 may include a Wi-Fi controller 352, a cellular controller (e.g., an LTE and / or LTE-A controller) 354, and a BLUETOOTH controller. TM Controller 356, and in at least some embodiments, one or more of these controllers may be implemented as corresponding integrated circuits (referred to as ICs or chips), which communicate with each other and with the SOC 300 (more specifically with the processor 302). For example, Wi-Fi controller 352 may communicate with cellular controller 354 via a cell-ISM link or WCI interface, and / or BLUETOOTH TMController 356 can communicate with cellular controller 354 via a cell-ISM link or the like. Although three separate controllers are shown within radio component 330, other implementations with fewer or more similar controllers for various different RATs can be implemented in UE device 106.

[0080] Furthermore, implementation schemes in which the controller can perform functions associated with various radio access technologies are envisioned. For example, according to some implementation schemes, in addition to hardware and / or software components for performing cellular communications, the cellular controller 354 may also include hardware and / or software components for performing one or more activities associated with Wi-Fi, such as Wi-Fi preamble detection, and / or the generation and transmission of Wi-Fi physical layer preamble signals.

[0081] Figure 4 - Block diagram of an exemplary base station

[0082] Figure 4 A block diagram of an exemplary base station 102 according to some implementation schemes is shown. It should be noted that... Figure 4 The base station shown is merely one example of a possible base station. As illustrated, base station 102 may include a processor 404 capable of executing program instructions specific to base station 102. Processor 404 may also be coupled to a memory management unit (MMU) 440 or other circuitry or device, which may be configured to receive addresses from processor 404 and translate those addresses into locations in memory (e.g., memory 460 and read-only memory (ROM) 450).

[0083] Base station 102 may include at least one network port 470. Network port 470 may be configured to be coupled to a telephone network and provide access rights as described above. Figure 1 and Figure 2 The telephone network described herein includes multiple devices such as UE device 106. Network port 470 (or an additional network port) may also be configured, or alternatively configured, to be coupled to a cellular network, such as the core network of a cellular service provider. The core network may provide mobility-related services and / or other services to multiple devices such as UE device 106. In some cases, network port 470 may be coupled to the telephone network via the core network, and / or the core network may provide the telephone network (e.g., in other UE devices served by the cellular service provider).

[0084] Base station 102 may include at least one antenna 434 and possibly multiple antennas. One or more antennas 434 may be configured to operate as a wireless transceiver and may be further configured to communicate with UE device 106 via radio component 430. Antenna 434 communicates with radio component 430 via communication link 432. Communication link 432 may be a receive link, a transmit link, or both. Radio component 430 may be designed to communicate via various wireless telecommunication standards, including but not limited to NR, LTE, LTE-A WCDMA, CDMA2000, etc. Processor 404 of base station 102 may be configured to implement and / or support implementation of some or all of the methods described herein, for example by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium). Alternatively, processor 404 may be configured as a programmable hardware element such as a FPGA (Field-Programmable Gate Array), or as an ASIC (Application-Specific Integrated Circuit), or a combination thereof. In the case of certain RATs (e.g., Wi-Fi), base station 102 can be designed as an access point (AP), in which case network port 470 can be implemented to provide access to a wide area network and / or one or more local area networks, for example it may include at least one Ethernet port, and radio component 430 can be designed to communicate according to the Wi-Fi standard.

[0085] Reference signal

[0086] Wireless devices (such as user equipment) can be configured to perform various tasks, including using reference signals (RS) provided by one or more cellular base stations. For example, initial access and beam measurements of the wireless device can be performed, at least in part, based on synchronization signal blocks (SSBs) provided by one or more cells within the communication range of the wireless device from one or more cellular base stations. Another type of reference signal typically provided in cellular communication systems can include channel state information (CSI) RS. In addition to various possibilities, various types of CSI-RS can be provided for tracking (e.g., for time and frequency offset tracking), beam management (e.g., CSI-RS configured to have repetition to help determine one or more beams for uplink and / or downlink communication), and / or channel measurement (e.g., CSI-RS configured in a resource set for measuring the quality of the downlink channel and reporting information related to that quality measurement to the base station). For example, in the case where CSI-RS is used for CSI acquisition, the UE can periodically perform channel measurements and send channel state information (CSI) to the BS. The base station can then receive and use the channel state information during communication with the wireless device to determine adjustments to various parameters. Specifically, the BS can use the received channel state information to adjust the coding of its downlink transmission to improve downlink channel quality.

[0087] In many cellular communication systems, base stations may periodically transmit some or all of these reference signals (or pilot signals), such as SSB and / or CSI-RS. In some cases, aperiodic reference signals may also be provided (e.g., aperiodic reference signals for aperiodic CSI reporting).

[0088] As a detailed example, according to at least some implementation schemes, in the 3GPP NR cellular communication standard, the channel state information from the UE based on the CSI-RS feedback used for CSI acquisition may include one or more of the following: Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI), Rank Indicator (RI), CSI-RS Resource Indicator (CRI), SSBRI (SS / PBCH Resource Block Indicator and Layer Indicator (LI)).

[0089] Channel quality information can be provided to the base station for link adaptation, for example, to provide guidance on which modulation and coding scheme (MCS) the base station should use when transmitting data. For instance, when the downlink channel communication quality between the base station and the UE is determined to be high, the UE can report a high CQI value, which allows the base station to transmit data using a relatively high modulation order and / or a low channel coding rate. Conversely, when the downlink channel communication quality between the base station and the UE is determined to be low, the UE can report a low CQI value, which allows the base station to transmit data using a relatively low modulation order and / or a high channel coding rate.

[0090] PMI feedback can include preferred precoding matrix information and can be provided to the base station to indicate which MIMO precoding scheme the base station should use. In other words, the UE can measure the quality of the downlink MIMO channel between the base station and the UE based on pilot signals received on the channel, and can recommend which MIMO precoding scheme the base station should apply via PMI feedback. In some cellular systems, the PMI configuration is represented in matrix form, providing linear MIMO precoding. The base station and UE can share a codebook consisting of multiple precoding matrices, where each MIMO precoding matrix in the codebook can have a unique index. Therefore, as part of the channel state information fed back by the UE, the PMI can include indices (or possibly multiple indices) corresponding to the most preferred MIMO precoding matrix (or matrices) in the codebook. This allows the UE to minimize the amount of feedback information. Thus, at least according to some embodiments, the PMI can indicate which precoding matrix from the codebook should be used for transmission to the UE.

[0091] For example, when the base station and UE have multiple antennas, Rank Indicator Information (RI Feedback) can indicate the number of transport layers that the UE determines can be supported by the channel, which can enable multi-layer transmission through spatial multiplexing. RI and Rank Indicator Information (PMI) together allow the base station to know which precoding needs to be applied to which layer, for example, depending on the number of transport layers.

[0092] In some cellular systems, the PMI codebook is defined based on the number of transport layers. In other words, for R-layer transport, N N-layer codebooks can be defined. t ×R matrix (e.g., where R represents the number of layers, N t Let R represent the number of transmitter antenna ports, and N represent the codebook size. In such a scenario, the number of transport layers (R) can correspond to the rank (N) of the precoding matrix. t The matrix is ​​a ×R matrix, and therefore R can be called the "rank indicator (RI)" in this context.

[0093] Therefore, channel state information may include an assigned rank (e.g., a rank indicator or RI). For example, a MIMO-enabled UE communicating with a BS may include four receiver chains, for example, four antennas. The BS may also include four or more antennas to enable MIMO communication (e.g., 4×4 MIMO). Thus, the UE can simultaneously receive up to four (or more) signals (e.g., layers) from the BS. Layer-to-antenna mapping can be applied, for example, mapping each layer to any number of antenna ports (e.g., antennas). Each antenna port can transmit and / or receive information associated with one or more layers. The rank may include multiple bits and may indicate the number of signals the BS can send to the UE in an upcoming time period (e.g., during an upcoming transmission time interval or TTI). For example, a rank 4 indicator may indicate that the BS will send four signals to the UE. As a possibility, the RI length may be two bits (e.g., since two bits are sufficient to distinguish four different rank values). It should be noted that, depending on various embodiments, other numbers and / or configurations of antennas (e.g., at either or both of the UE or BS) and / or other numbers of data layers are also possible.

[0094] Figure 5 - Neighboring cell measurement

[0095] Wireless devices in cellular communication systems typically perform neighboring cell measurements (e.g., measurements of cells that may be nearby but not the current serving cell) and serving cell measurements at various times, for example, in addition to performing data and control communications. Such measurements can support consistently good reception and facilitate cell handover and reselection, for example, in a variety of other applications. Many types of signals and channels may exist that can be used for various types of measurements and communications with neighboring and serving cells. Furthermore, many types of wireless devices may exist that have different capabilities for operating within a given cellular communication system.

[0096] In 3GPP Releases 15 and 16, Layer 1 (L1) measurements could be configured (e.g., only) for serving cell measurements. L1 measurements for neighboring cells might not be supported. In Release 17, intra-frequency L1 measurements for neighboring cells are supported. However, inter-frequency L1 measurements for neighboring cells are also possible. For example, future technical specifications (TS) 38.133 may include measurement requirements for inter-frequency L1 measurements for neighboring cells.

[0097] In the various embodiments described herein, the measurement period for inter-frequency L1 measurements of neighboring cells can be determined. For example, various embodiments may include any or all of the following measurements in a variety of possibilities: L1 reference signal received power (RSRP) measurement based on neighboring cell synchronization signal (SSB), L1-RSRP measurement based on neighboring cell channel state information (CSI) reference signal (RS, e.g., CSI-RS), neighboring cell L1 signal-to-interference-plus-noise ratio (SINR) configured with SSB-based channel measurement resources (CMR) and dedicated interference measurement resources (IMR), neighboring cell L1-SINR configured with CSI-RS-based CMR but without dedicated IMR, and neighboring cell L1-SINR configured with CSI-RS-based CMR and dedicated IMR.

[0098] In version 17, multi-beam (e.g., multiple-input multiple-output (MIMO)) enhancements may be considered to support L1 and / or L2 center mobility and inter-cell multiple transmit and receive points (mTRP).

[0099] In some implementations, neighboring cell measurements can be configured via SSB Measurement Timing Configuration (SMTC). SMTC can be configured for L3-based neighboring cell measurements. The SMTC periodicity may be common to all neighboring cell measurements. For example, the SMTC periodicity could be 160ms. However, in some implementations, the SSB of the neighboring cell being measured (e.g., CellX) may have a shorter periodicity, such as 40ms. Therefore, the UE may only perform measurements during the SMTC period, and thus may not perform measurements during some SSB periods within the SSB period. As a result, the measurement may take longer (e.g., four times longer).

[0100] One objective of L1 and / or L2 center mobility could be faster inter-cell beam switching and / or handover. Therefore, such measurements are limited to an SMTC-extendable measurement period. This extension of the measurement period can delay mobility (e.g., beam switching, handover, etc.).

[0101] In this disclosure, methods for enhancing L1 and / or L2 center mobility and inter-cell mTRP neighbor cell L1 measurements are discussed.

[0102] To illustrate a possible set of implementation schemes for this type, Figure 5 This is a communication flowchart illustrating, at least according to some implementations, a method for a UE to operate in a cellular communication system when neighboring cell measurements are configured according to a framework that aligns the expectations and behaviors of the wireless device and the cellular network by incorporating neighboring cell measurements.

[0103] Figure 5 Aspects of the method can be implemented by wireless devices, such as a UE 106 in conjunction with one or more cellular base stations, such as a serving cell 501 and neighboring cells 503 (or multiple neighboring cells 503). The serving cell 501 and neighboring cells 503 can be provided by one or more BS 102 and / or TRP. The various figures herein show and describe the UE 106 and / or BS 102, or more generally, they can be shown and described as needed in conjunction with any of the computer circuits, systems, devices, elements, or components shown in the figures above. For example, the processor (and / or other hardware) of such devices can be configured to cause the devices to perform any combination of the illustrated method elements and / or other method elements. For example, one or more processors (or processing elements) (e.g., processors 302, 404, baseband processors, processors associated with communication circuits such as 330, 430, or 432, processors associated with various core network elements, etc., and various possible processors) can cause the UE, network, network elements, BS, or other devices to perform such method elements.

[0104] It should be noted that, although the description uses methods involving the use of communication technologies and / or features associated with 3GPP and / or NR specification documents, Figure 5 This method describes at least some elements, but this description is not intended to limit this disclosure and can be used in any suitable wireless communication system as needed. Figure 5 The method encompasses various aspects. In various implementation schemes, some elements of the method shown may be performed simultaneously in a different order than those shown, may be replaced by other method elements, or may be omitted. Additional method elements may also be performed as needed. As shown in the figure, Figure 5 The method can be operated as follows.

[0105] The UE may establish communication with the serving cell via a radio link according to some implementation schemes (502). For example, the radio link may include a cellular link based on 5G NR. The UE may establish a session with the AMF entity of the cellular network via the serving cell, which may operate according to NR. As another possibility, the radio link may include a cellular link based on LTE. For example, the UE may establish a session with the Mobility Management Entity (MME) of the cellular network via the serving cell, which may operate according to LTE. According to various implementation schemes, other types of cellular links and management equipment are also possible, and the cellular network may also or alternatively operate according to another cellular communication technology (e.g., UMTS, CDMA2000, GSM, etc.).

[0106] Establishing a radio link may include establishing an RRC connection. Establishing an RRC connection may include configuring various parameters for communication between the UE and the serving cell, establishing environmental information, and / or any of various other possible features, such as establishing an air interface for the UE to communicate with a cellular network associated with a cellular base station.

[0107] According to at least some implementations, a UE can establish multiple radio links, for example, with multiple TRPs in a cellular network, based on a multi-TRP configuration. In such scenarios, the UE can be configured (e.g., via RRC signaling) to have one or more Transmission Control Indicators (TCIs), which may correspond to various beams available for communication with the TRPs. Furthermore, there may be situations where one or more configured Transmission Control Indicator (TCI) states can be activated at a specific time by the UE's Media Access Control (MAC) control element (CE).

[0108] In at least some cases, establishing a radio link may include the UE providing its capability information. This capability information may include information related to any of a variety of UE capabilities.

[0109] In some cases, this capability information may include information indicating whether the UE supports simultaneous reception of reference signals for neighboring cell measurements. For example, the capability information may indicate whether the UE supports concurrent CSI-RS-based neighboring cell measurements and serving cell PDCCH or PDSCH reception, for example, with different subcarrier spacings (also referred to as parameters). This capability information may relate to one or more of the 3GPP Layer 1 (L1) or Layer 3 (L3) neighboring cell measurements for one or more of the intra-frequency or inter-frequency measurements. Similarly, the capability information may indicate whether the UE supports simultaneous reception of reference signals for neighboring cell measurements and reference signals for serving cell measurements, and any limitations on this capability (e.g., based on different parameters). As another example, such capabilities may include the number of one or more L1 measurements that the radio device is capable of performing (e.g., the maximum number of L1 measurements that the radio device is capable of performing in each of one or more scenarios or sets of conditions, such as non-zero power (NZP) CSI-RS resources and SSB for one port, NZP CSI-RS resources for two ports, non-periodic CSI-RS resources, etc.). According to various implementation schemes, this capability information can be provided as a combination of capability information for both L1 neighboring and serving cell measurements, or it can be provided as specific capability information for L1 neighboring cell measurements.

[0110] According to some implementations, the serving cell may provide configuration information (504) to the UE. This configuration information may indicate a measurement configuration for L1 frequency-to-frequency measurements between non-serving cells. For example, the configuration information may indicate the periodicity, index, and / or time and / or frequency resources of reference signals transmitted by one or more neighboring cells. Additional and / or different characteristics of the reference signals and / or measurements may be indicated. In some implementations, the configuration information may be (e.g., in part) based on UE capability information. In some implementations, the configuration information may include measurement configurations for the serving cell and / or for higher-level (e.g., L3, etc.) measurements for non-serving cells. In various possibilities, the configuration information may be used to assist the UE in detecting, measuring, and reporting non-serving cells. The configuration information may describe various types of reference signals (RS), such as SSB, CSI-RS, etc. Various examples of configuration information for L1 measurements of non-serving cells are provided below.

[0111] The UE can be configured with L1-RSRP and / or L1-SINR on the SSB and / or CSI-RS of non-serving cells. For example, L1 and CSI measurements (e.g., serving cell only) can be configured via the CSI-ReportConfig information element (IE). To support L1 measurements and reporting for non-serving cells, similar reporting configurations can be configured for non-serving cells. For example, a new CSI-ReportConfig-nonServing IE can be added to the standard for this purpose. Alternatively, the CSI-ReportConfig IE can be extended / enhanced to include non-serving cells. For example, the CSI-ReportConfig IE and / or the CSI-ReportConfig-nonServing IE can include relevant fields regarding measurement reporting and / or RS (e.g., SSB) configuration for non-serving cells, as further explained below.

[0112] In some implementations, in addition to the relevant fields required for reporting measurements of non-serving cells, the configuration information also indicates the configuration of reference signals for the non-serving cells. For example, the configuration information may indicate RS (e.g., SSB and / or CSI-RS, etc.) configuration. Furthermore, configurations including RS periodicity and / or indexing of neighboring cells can allow the UE to avoid cell detection and measurement time. It should be understood that, in this context, "cell detection and measurement time" can refer to the amount of time the UE would spend (e.g., blind) detecting, decoding, and correlated measurements to identify the RS of the non-serving cell. Such cell detection and measurement time can be reduced or eliminated based on configuration information indicating the time / frequency location of the RS, thereby avoiding the need for blind detection and decoding. Furthermore, such configurations can facilitate the UE measuring non-serving cells outside the time used for measuring the serving cell (e.g., according to the SSB Measurement Timing Configuration (SMTC)). As mentioned above, the SMTC can describe the time for L3 measurements of the SSB of neighboring cells. However, for L1 inter-frequency measurements of neighboring cells (e.g., using SSB), the UE can perform measurements outside the SMTC time / frequency resources. In other words, such a configuration can facilitate the UE to utilize additional transmissions of the SSB and / or other RS ​​of the non-serving cell (e.g., possibly every transmission during the measurement period).

[0113] Figure 6Examples of configuration information showing possible variations in the use of SMTC configuration according to some implementation schemes are illustrated, such as enhancements for non-serving cells. As shown, a separate SMTC configuration (e.g., referred to as SSB-MTC-L1-r17, for example) can be provided in the IE for any or all non-serving cells configured for L1 measurements. Therefore, a dedicated configuration for L1 measurements of non-serving cells can be provided on a per-serving-cell basis. This approach allows the network to flexibly configure non-serving-cell measurements separately from other SMTCs (e.g., those of the serving cell). The SMTC configuration provides the UE with the ability to detect, measure, and report L1-RSRP (and / or SINR or other measurements) on RS (e.g., SSB) from any non-serving cell.

[0114] Another aspect of the configuration information may include new or modified scaling factors. Carrier-specific scaling factors (CSSFs) are described in Clause 9.1.5 of TS 38.133. CSSFs can be used to scale measurement timing parameters, such as measurement delay requirements. CSSFs may include those discussed in 9.1.5.1. outside_gap And CSSF, which can be discussed in 9.1.5.2 within_gap In many cases, L1 measurements between frequencies can be performed within the measurement interval. Therefore, CSSF within_gap This can be applied to inter-frequency L1 measurements between adjacent cells. For example, the measurement period for inter-frequency L1 measurements on a first adjacent cell can be based on a CSSF, which can be based on the total number of inter-frequency layers configured for L1 measurements (e.g., the first adjacent cell) during the measurement interval.

[0115] In some implementations, CSSF within_gap Various aspects may be modified as described herein, for example, to accommodate or support inter-frequency L1 measurements between adjacent cells. For example, the discussion of CSSF in existing sections from 9.1.5.2.1 to 9.1.5.2.5 (and / or similar documents) may be updated as described below.

[0116] Specifically, the parameter (M) that can be adjusted indicates the number of layers within the gap that are candidates for measurement. tot ) to include the number of L1 measurements. For example, M tot It can be used to calculate CSSF within_gap The parameters are as follows: 9.1.5.2.1 EN-DC mode: Carrier-specific scaling factor for L3 measurements based on SSB and CSI-RS performed within the gap. Specifically, M tot,i,j It can be calculated as a sum: M intra,i,j +M inter,i,j Parameter i can refer to the object being measured, i. Parameter j can refer to a specific gap, j. M intra,i,jThis can refer to the number of objects to be measured within the frequency range, including both SSB-based and CSI-RS-based measurements, which are candidates to be measured in gap j, where object i is also a candidate. Similarly, M inter,i,j This can refer to the number of NR inter-frequency layers, including NR RAT inter-frequency layers configured by E-UTRA PCell based on both SSB and CSI-RS, EUTRA inter-frequency measurement objects configured by E-UTRA PCell, or UTRA RAT inter-measurement objects configured by E-UTRA PCell, which are candidates to be measured in gap j, where measurement object i is also a candidate. The number of layers used for measurement can refer to the number of frequency layers used for measurement. Therefore, the number of layers is different from the number of layers being measured (e.g., L1, L3, etc.). According to some implementations, M inter,i,j This could refer only to high-level measurements (e.g., L3) and may not include L1 measurements. Therefore, a new item can be added to M. tot,i,j In the calculation, represents the number of (e.g., frequency) layers used for L1 measurements (e.g., inter-frequency measurements between neighboring cells). In some implementations, such a new term can be described as M. inter,i,j_L1 M inter,i,j_L1 This can describe the total number of inter-frequency layers to be measured that are configured with L1-RSRP and / or L1-SINR in gap j, where the measurement object i is also a candidate. M inter,i,j_L1 This describes the number of frequency layers used for such L1 frequency measurements between adjacent cells. Therefore, M tot,i,j It can be calculated as M intra,i,j +M inter,i,j +M inter,i,j_L1 It should be understood that the specific identifier M provided... inter,i,j_L1 The identifiers and descriptions are examples, and different identifiers and / or descriptions may be used as needed.

[0117] A specific example of the potential revised text in 9.1.5.2.1 is as follows:

[0118] The scaling values ​​in the following text (CSSF) within_gap,i It was derived without considering the inter-carrier of GSM RAT.

[0119] When monitoring one or more measurement objects within a measurement gap, the carrier-specific scaling factor for the target measurement object with index i is specified as CSSF. within_gap,i And exported as described in that clause.

[0120] If the measurement object i refers to a periodic Tprs > 160ms or a periodic Tprs = 160ms but RSTD measurement is configured with prs-MutingInfo-r9, then CSSF within_gap,i=1. Otherwise, other measurement objects (including periodic RSTD measurements with Tprs = 160 ms) participate in the CSSF gap competition. within_gap,i Export as follows.

[0121] For each measurement gap j that is not used for RSTD measurements with periodic Tprs > 160ms or periodic Tprs = 160ms but configured with prs-MutingInfo-r9 within any 160ms period, the total number of intra-frequency measurement objects and inter-frequency / RAT measurement objects that are candidates for measurement within the statistical gap j is counted.

[0122] -If the SMTC duration of an NR measurement object configured with SSB measurement is fully covered by MGL (excluding RF switching time), then the NR measurement object is a candidate to be measured in the gap. For an in-frequency NR carrier, if the higher layer in the TS 38.331[2] signaling configured with smtc2 is configured, then the periodicity of the assumed SMTC timing corresponds to the value of the higher layer parameter smtc2; otherwise, the periodicity of the assumed SMTC timing corresponds to the value of the higher layer parameter smtc1.

[0123] - If the window restricting all CSI-RS resources is fully covered by MGL (excluding RF switching time), then the NR measurement object configured for CSI-RS measurement is a candidate to be measured in the gap.

[0124] - The RAT-interval UTRA measurement object configured by E-UTRA PCell

[15] is a candidate to be measured in all measurement gaps.

[0125] - The frequency-inter-frequency E-UTRA measurement object configured by the E-UTRA PCell

[15] is a candidate to be measured in all measurement gaps.

[0126] - For UEs that support and configure each FR gap, statistics are performed on a per FR basis, and for UEs that configure each UE gap, statistics are performed on a per UE basis.

[0127] -M intra,i,j The number of objects to be measured within the frequency range, including both SSB-based and CSI-RS-based objects, which are candidates to be measured in gap j, where object i is also a candidate.

[0128] Otherwise, M intra,i,j It equals 0.

[0129] -M inter,i,jThe number of NR inter-frequency layers includes NR RAT inter-frequency layers based on both SSB and CSI-RS configured by the E-UTRA PCell, EUTRA inter-frequency measurement objects configured by the E-UTRA PCell, or UTRA RAT inter-measurement objects configured by the E-UTRA PCell. These are candidates to be measured in gap j, where measurement object i is also a candidate. Otherwise, M inter,i,j It equals 0.

[0130] -M inter,i,j_L1 The total number of inter-frequency layers to be measured, configured with L1-RSRP and / or L1-SINR in gap j, where measurement object i is also a candidate. Otherwise, M inter,i,j_L1 It equals 0.

[0131] -M tot,i,j =M intra,i,j +M inter,i,j +M inter,i,j_L1 : The total number of frequency layers within, between, and between RATs that are candidates to be measured in gap j, where the object to be measured i is also a candidate.

[0132] Otherwise, Mtot,i,j equals 0.

[0133] It should be understood that similar additions and revisions may be applied to other parts of TS 38.133 and / or other documents. For example, similar additions may be introduced in sections 9.1.5.2.2 to 9.1.5.2.4 of TS 38.133, which may relate to SA mode, NE-DC and NR-DC respectively.

[0134] As another possible example of configuration information, this information may involve the calculation of the measurement period (e.g., in a manner different from or other than via CSSF calculation). For example, new sections could be added to specifications (e.g., TS 38.133 and / or other documents) to describe L1-RSRP and / or L1-SINR measurements. Such new sections could describe the measurement period (e.g., for inter-frequency L1 measurements of neighboring cells) as a function of the RS periodicity of neighboring cells. As a possibility, the measurement period could be based on the larger of MGRP and / or RS periodicity. Potential variations in inter-frequency measurements of L1-RSRP and L1-SINR for neighboring cells are described below. L1-RSRP is described first, followed by L1-SINR.

[0135] Existing L1-RSRP measurement requirements for serving cells are specified in Clause 9.5 of TS 38.133. However, the current description in TS 38.133 may not cover inter-frequency L1 measurements between neighboring cells. Therefore, to support inter-frequency L1-RSRP measurements between neighboring cells, new measurement descriptions and / or requirements may be added. For example, new sections (or sections) may be introduced to describe such measurements. Among various possibilities, new sections may be added to the end of 9.5. For example, it could be added as: 9.5.x Inter-frequency L1-RSRP Measurements. Subsections for SSB-based and / or CSI-RS measurements may be included, such as: 9.5.x.1 SSB-based Inter-frequency L1-RSRP Measurements and 9.5.x.2 CSI-RS-based Inter-frequency L1-RSRP Measurements. It should be understood that the numbering and headings provided herein are examples, and such sections may be added in various other places in TS 38.133 or other documents.

[0136] Available Figures 7 to 10 More details regarding the L1-RSRP measurements are provided below and discussed in relation to these figures.

[0137] It should be noted that the measurement reporting requirements defined in 9.5.3 also apply to inter-frequency L1-RSRP measurements. In some implementations, 9.5.3 may not need to be updated. In some implementations, 9.5.3 may be modified. It should be noted that 9.5.4 may include a description of L1-RSRP measurements for the serving cell.

[0138] Existing L1-SINR measurement requirements for serving cells can be specified in Clause 9.8 of TS 38.133. However, the current description in TS 38.133 may not cover inter-frequency L1 measurements between adjacent cells. Therefore, to support inter-frequency L1-SINR measurements between adjacent cells, new measurement descriptions and / or requirements may be added. For example, new sections (or sections) may be introduced to describe such measurements. Among various possibilities, new sections may be added to the end of 9.8. For example, it could be added as: 9.8.x Inter-frequency L1-SINR measurements. Subsections may include measurements based on SSB and / or CSI-RS, such as: 9.8.x.1 L1-SINR reporting with CSI-RS-based CMR and no dedicated IMR configured, 9.8.x.2 L1-SINR reporting with SSB-based CMR and dedicated IMR configured, and 9.8.x.3 L1-SINR reporting with CSI-RS-based CMR and dedicated IMR configured.

[0139] Available Figures 11 to 16 More details are provided in relation to L1-SINR measurements, and these figures are discussed below.

[0140] It should be noted that the measurement reporting requirements defined in 9.8.3 also apply to inter-frequency L1-SINR measurements. In some implementations, 9.8.3 may not need to be updated. In some implementations, 9.8.3 may be modified. It should be noted that 9.8.4 may include a description of L1-SINR measurements for the serving cell.

[0141] In some implementations, the configuration information may include additional or different related and / or unrelated aspects of communication between the UE and the network (e.g., serving cell and / or neighboring cells).

[0142] For example, this configuration may specify one or more frequencies, bands, frequency ranges, component carriers, etc., for which the UE is configured to perform measurements. As an option, this configuration information may indicate the inter-frequency measurement configuration for neighboring cells L1 for frequency range 1 (FR1) and / or FR2 (e.g., as described in 3GPP specifications such as TS 38.104).

[0143] For example, this configuration information can provide discontinuous reception (DRX) cycle information. For instance, the configuration information may include the DRX cycle length and / or information about how / when to apply DRX.

[0144] Different configuration information can be provided for different types of RS scheduling. For example, the configuration information can be different for persistent, semi-persistent, and / or aperiodic RS (e.g., CSI-RS and / or SSB).

[0145] According to some implementation schemes, the UE may determine one or more measurement configurations or measurement configuration parameters for L1 measurements in neighboring cells (506). The UE may determine the configuration or parameters based on this configuration information and / or other factors.

[0146] For any single neighboring cell or cell group, the UE can determine: what L1 inter-frequency measurements (e.g., SINR or RSRP, etc.) to perform; when to perform the measurements (e.g., measurement cycle); what RS (e.g., CSI-RS and / or SSB, etc.) to use for the measurements; what frequency, frequency range, etc. to use; and when and how to report the measurements (e.g., how often). It should be understood that, depending on some implementations, different measurement cycles (and / or other characteristics) can be determined for different measurement types. For example, one measurement cycle can be determined for L1-RSRP, and different measurement cycles can be determined for L1-SINR.

[0147] In some implementations, to determine the measurement period, the UE may determine one or more relevant quantities (e.g., parameters used to calculate the measurement period). For example, the UE may determine one or more CSSFs, one or more reporting periods (e.g., T...). report), one or more RS cycles (e.g., T) SSB T CSI-RS etc.), DRX cycle time (e.g., T DRX ), sharing coefficient (e.g., P), MGRP and / or other factors (e.g., M, N, etc., as described in 9.5.4 and / or 9.8.4 of TS 38.133).

[0148] In some implementations, the UE may, for example, determine the characteristics of RSs of neighboring cells based on the configuration information. The UE may determine such characteristics of one or more individual cells; for example, different neighboring cells may have different characteristics, and the UE may determine the individual characteristics of any number of neighboring cells (e.g., as indicated in the configuration information). The UE may determine the characteristics of various types of RSs (e.g., CSI-RS, SSB, etc.) for any neighboring cell. The UE may determine periodicity and / or time and / or frequency resources for various characteristics of RSs. Similarly, the UE may determine an index for RSs. It should be understood that in implementations where the characteristics of RSs of neighboring cells are indicated in the configuration information, the UE may determine such characteristics without performing a search for RSs of neighboring cells. For example, based on the characteristics of RSs included in the configuration information (e.g., in various possibilities, in the report configuration message), the UE may determine the time / frequency location of RSs and may avoid searching for RSs. The UE may determine the time and / or frequency resources for various types of measurements for various neighboring cells. For example, the UE can determine a first time / frequency resource for L1-RSRP measurement of the first neighboring cell, a second time / frequency resource for L1-SINR measurement of the first neighboring cell, a third time / frequency resource for L1-RSRP measurement of the second neighboring cell, a fourth time / frequency resource for L1-SINR measurement of the second neighboring cell, and so on. Any of the time / frequency resource sets may overlap in the time domain and / or frequency domain, or these sets may be disjoint.

[0149] Such characteristics can be determined for one or more frequency bands of any cell (e.g., FR1, FR2, etc.). Similarly, such characteristics can be determined based on UE operations, such as the UE's DRX cycle. Furthermore, such characteristics can be determined for persistent, semi-persistent, and / or aperiodic RS (e.g., CSI-RS and / or SSB). In other words, different RS schedules can have different characteristics.

[0150] Therefore, the UE can determine different measurement configurations at different times. For example, at a first time, the UE can operate according to a first DRX cycle (e.g., including operation without DRX, such as non-DRX) and / or a first frequency band. At a second time, the UE can operate according to a second DRX cycle and / or a second frequency band. The UE can determine L1 measurement parameters between different frequencies of neighboring cells based on different DRX and / or frequency bands, for example, in combination with received configuration information. In other words, in response to detecting a change in DRX and / or frequency band, the UE can determine a change in measurement parameters.

[0151] In some implementations, the UE may determine the SMTC configuration for one or more non-serving cells.

[0152] According to some implementation schemes, neighboring cells may transmit RS (508). RS may be transmitted according to a configuration consistent with the configuration information (e.g., discussed in 504). For example, RS may be transmitted periodically and / or on time / frequency resources consistent with the configuration information. RS may use an index consistent with the configuration information (e.g., one or more indices). The UE may receive RS from one or more neighboring cells. Among various possibilities, RS may include CSI-RS and / or SSB. RS may be persistent, semi-persistent, and / or non-periodic.

[0153] According to some implementation schemes, the UE can perform measurements of RS received from neighboring cells (510). The UE can perform the measurements according to a configuration consistent with this configuration information (e.g., discussed in 504 and 506). For example, in various possibilities, the UE can perform the measurements periodically according to a measurement period determined in 506. The measurement can be or includes L1 inter-frequency measurements. For example, the UE can measure L1-RSRP and / or L1-SINR of CSI-RS and / or SSB transmitted by neighboring cells.

[0154] In some implementations, it is possible to do so without regard to the SMTC period associated with the serving cell (e.g., T). SMTCperiod At least some of the measurements are executed during the scheduled time.

[0155] In some implementations, measurements can be performed based on the SMTC cycle or SMTC configuration of the non-serving cell.

[0156] In some implementations, event-based measurements can be performed.

[0157] According to some implementation schemes, the UE may report measurements or information based on measurements of the serving cell (512). For example, the UE may periodically transmit reports of measurement values ​​to the serving cell, for example, according to the reporting period and / or SMTC configuration for L1 frequency inter-frequency measurements on non-serving cells determined in 506.

[0158] In some implementations, event-based measurement reports may be provided.

[0159] Figures 7 to 16 -Example Measurement Periodic Table

[0160] Figures 7 to 16 Various examples of calculating measurement cycles and / or related parameters are shown (e.g., as described above with respect to 506).

[0161] As described above, a new section of the specification (e.g., section 9.5.x.1, possibly added as TS 38.133) describes inter-frequency L1-RSRP measurements based on SSBs. This section specifies that the UE should be able to perform inter-frequency L1-RSRP measurements based on the SSB resources configured for L1-RSRP calculation, and that the UE physical layer should be able to report the L1-RSRP measured within the measurement period. In various possibilities, the measurement period may be denoted as T. Inter-L1-RSRP_Measurement_Period_SSB According to some implementation schemes, T is used to determine Inter-L1-RSRP_Measurement_Period_SSB Example table of values ​​in Figure 7 China targets FR1 and Figure 8 The document provides an explanation for FR2. Figure 7 and Figure 8 The following parameters can be used:

[0162] If the higher-level parameter timeRestrictionForChannelMeasurement is configured, then M=1; otherwise, M=3.

[0163] N = 8.

[0164] Because of the overlap between L1 measurements, the SMTC used for L3 measurements, and the measurement gap (MG), P may be a scaling factor. The value of P can vary depending on the scenario; for example, it may depend on the level of overlap between L1 measurement resources (e.g., for SSB-based L1 inter-frequency RSRP), the SMTC (e.g., for L3 measurements in neighboring cells), and the measurement gap. In other words, P may depend on the amount of overlap in the time domain between these three events. For example, if there is no overlap between L1 measurements and the SMTC or measurement gap, P may be 1. If there is partial overlap between L1 measurements and the SMTC and / or measurement gap, P may be greater than 1. It should be understood that different measurement gaps can be configured for intra-frequency, inter-frequency, and / or inter-RAT measurements. In some implementations, a measurement gap specific to L1 inter-frequency measurements in neighboring cells can be used to calculate P. In some implementations, measurement gaps for inter-frequency, intra-frequency, and / or inter-RAT (e.g., L1 and / or L3) measurements in the serving cell and / or neighboring cells can be used to calculate P. The MGRP may be a measurement gap repetition period configured with an MG mode.

[0165] CSSF inter This can be a scaling factor used to measure multiple layers. Note that CSSF... inter It can be determined according to the methods described herein (e.g., in conjunction with the number of layers used for inter-frequency L1 measurements of adjacent cells).

[0166] about Figure 7 and Figure 8 T DRX This can be the applicable / current DRX cycle length (e.g., for the UE in the relevant frequency band). T Report This can be configured for periodicity in reporting. In some implementations, when T... SSB When ≤40ms and highSpeedMeasFlag-r16 is configured, K=1; otherwise, K may equal 1.5 in various possibilities. Furthermore, in Figure 7 and Figure 8 (and more generally, Figures 7 to 16 In the case of any / all of the parameters, it should be understood that any or all of the parameters may be cell-specific. For example, according to some implementation schemes, T SSB (As shown in the figure in this application) can be used for neighboring cells. This type of parameter can be represented as T. SSB T SSB It could be "ssb-periodicityNeighborCellX", indicating T SSB It is the periodicity of the SSB-Index configured for L1-RSRP measurements of a specific neighboring cell X across various possibilities. Similarly, T Report This could refer to the reporting period used for L1-RSRP measurements in neighboring cells. Therefore, Figures 7 to 16 The parameters shown may have values ​​different from those in TS38.133 or other specifications. For example, T in the figure below... report It may have the T referenced in section 9.5.4 of TS 38.133. Report Different values.

[0167] As described above, a new section of the specification (e.g., section 9.5.x.2, possibly added as TS 38.133) describes inter-frequency L1-RSRP measurements based on CSI-RS. This section specifies that the UE should be able to perform L1-RSRP measurements based on the CSI-RS resources configured for L1-RSRP calculation, and that the UE physical layer should be able to report the L1-RSRP measured within the measurement period. In various possibilities, the measurement period may be denoted as T. Inter-L1-RSRP_Measurement_Period_CSI-RS Used to determine T Inter-L1-RSRP_Measurement_Period_CSI-RS Example table of values ​​in Figure 9 China targets FR1 and Figure 10 The description is provided for FR2. For these graphs, the parameters M and N may be similar to the scaling factors described in Clause 9.5.4.2 of the existing TS 38.133.

[0168] for Figure 9 and Figure 10 Since P may be a scaling factor due to the overlap between the L1 measurement, the SMTC used for the L3 measurement, and the measurement gap. P can be related to... Figure 7 and Figure 8 The calculation is performed in a similar manner. The P-value can vary depending on the scenario; for example, it can depend on the level of overlap between L1 measurement resources (e.g., for L1 inter-frequency RSRP based on CSI-RS), SMTC (e.g., for L3 measurements in neighboring cells), and measurement gaps. In other words, P can depend on the amount of overlap in the time domain between these three events.

[0173] According to some implementation schemes, these tables may be applicable if the CSI-RS resources configured for L1-RSRP measurements are emitted at a density of 3.

[0174] When T CSI-RS If the time is ≤40ms and highSpeedMeasFlag-r16 is configured, K can be set to K=1; otherwise, K=1.5.

[0175] In addition, Figure 9 and Figure 10 (and more generally, Figures 7 to 16 In the case of any / all of the parameters, it should be understood that any or all of the parameters may be cell-specific. For example, T CSI-RS This can be used for neighboring cells. This type of parameter can be represented as T. CSI-RS =SSI-CRS-periodicityNeighborCellX, which indicates the periodicity of the CSI-RS-Index configured for L1-RSRP measurements of a specific neighboring cell X in various possibilities. Similarly, T Report This can refer to the reporting period used for L1-RSRP measurements in neighboring cells, and may have the same T as referenced in section 9.5.4 of TS 38.133. Report Different values.

[0176] As described above, a new section of the specification (e.g., section 9.8.x.1, possibly added as TS 38.133) describes CSI-RS-based inter-frequency L1-SINR measurements when no dedicated IMR is configured. This section specifies that the UE should be able to perform L1-SINR measurements when the CSI-RS resource is configured for CMR and no dedicated resource is configured for an IMR for L1-SINR calculation, and that the UE physical layer should be able to report the L1-SINR measured within the measurement period. In various possibilities, the measurement period may be denoted as T. Inter-L1-SINR_Measurement_Period_CSI-RS_CMR_Only Used to determine T Inter-L1-SINR_Measurement_Period_CSI-RS_CMR_Only Example table of values ​​in Figure 11 China targets FR1 and Figure 12 The document provides an explanation of FR2.

[0177] In some implementations, for periodic and semi-persistent CSI-RS resources configured as Channel Measurement Resources (CMR), parameter M can be set to 1 (e.g., M=1) if a higher-layer parameter (e.g., timeRestrictionForChannelMeasurement) is configured, otherwise M=3. For aperiodic CSI-RS resources as CMR, M=1.

[0178] As mentioned above, relative to Figure 11 and Figure 12 Because of the overlap between the L1 measurement, the SMTC used for the L3 measurement, and the measurement gap, P can be a scaling factor. MGRP can be the measurement gap repetition period configured in the MG mode. CSSF inter This can be a scaling factor for measurements across multiple layers. Any or all of these parameters can be specifically set and / or determined for one or more neighboring cells. For example, CSSF... interIt can be determined according to the methods described herein (e.g., in conjunction with the number of layers used for inter-frequency L1 measurements of adjacent cells).

[0179] Similarly, T CSI-RS This can be the periodicity of a CSI-RS configured for L1-SINR measurements, such as for inter-frequency adjacent cell measurements. DRX This can be the DRX loop length. T Report This can be a configuration periodicity used for reporting, such as for inter-frequency adjacent cell measurements.

[0180] In some implementations, if the CSI-RS resources configured for L1-SINR measurements are transmitted at a density of 3, then Figure 11 and Figure 12 Possibly applicable.

[0181] As described above, a new section of the specification (e.g., section 9.8.x.2, possibly added as TS 38.133) describes SSB-based inter-frequency L1-SINR measurements when a dedicated IMR is configured. This section specifies that the UE should be able to perform L1-SINR measurements when the SSB is configured for CMR and the dedicated resource is configured for the IMR used for L1-SINR calculation, wherein the NZP-CSI-RS or CSI-IM resource configured as the dedicated IMR can be mapped one-to-one to the SSB configured as CMR at the same periodicity. The UE physical layer can then report the L1-SINR measured within the measurement period. In various possibilities, this measurement period may be referred to as T. Inter-L1-SINR_Measurement_Period_SSB_CMR_IMR In some implementations, this clause may not apply if an NZP-CSI-RS or CSI-IM resource configured as a dedicated IMR is scheduled to have a different periodicity than an SSB configured as a CMR.

[0182] According to some implementation schemes, T is used to determine Inter-L1-SINR_Measurement_Period_SSB_CMR_IMR Example table of values ​​in Figure 13 China targets FR1 and Figure 14 The document provides an explanation of FR2.

[0183] In some implementation schemes, for Figure 13 and Figure 14For periodic or semi-persistent NZPCSI-RS or CSI-IM resources used as dedicated IMRs, M = 1 if one or both of the high-level parameters timeRestrictionForChannelMeasurements and / or timeRestrictionForInterferenceMeasurements are configured; otherwise, M = 3. As mentioned above, P may be a scaling factor due to the overlap of L1 measurements, the SMTC used for L3 measurements, and the measurement gap. MGRP can be the measurement gap repetition period configured in MG mode. CSSF inter It can be a scaling factor measured across multiple layers. CSSF inter It can be determined according to the methods described herein (e.g., in conjunction with the number of layers used for inter-frequency L1 measurements of adjacent cells).

[0184] T SSB This can refer to the periodicity of the SSB-Index configured for L1-SINR channel measurements, for example, for inter-frequency measurements between adjacent cells. DRX This can be the DRX loop length. T Report This can be a configuration periodicity used for reporting, such as for inter-frequency adjacent cell measurements.

[0185] In some implementations, CSI-RS resources configured for interference measurements can be mapped one-to-one to SSBs configured for channel measurements with the same periodicity. In some implementations, Figure 13 and Figure 14 This type of 1-to-1 mapping can be applied to CSI-RS and SSB.

[0186] As described above, a new section of the specification (e.g., section 9.8.x.3, possibly added as TS 38.133) describes CSI-RS-based inter-frequency L1-SINR measurements when a dedicated IMR is configured. This section specifies that the UE should be able to perform L1-SINR measurements when the CSI-RS resource is configured for CMR and the dedicated resource is configured for the IMR used for L1-SINR calculation, where the NZP-CSI-RS or CSI Interference Measurement (CSI-IM) resource can be configured as a dedicated IMR, and the dedicated IMR should be mapped one-to-one to the CSI-RS resource configured for CMR at the same periodicity. The UE physical layer should be able to report the L1-SINR measured within the measurement period. In various possibilities, the measurement period may be labeled T. L1 - SINR_Measurement_Period_CSI-RS_CMR_IMRIn some implementations, this clause may not apply if NZP-CSI-RS or CSI-IM resources configured for dedicated IMR are scheduled to have a different periodicity than CSI-RS resources configured for CMR. In some implementations, this clause may apply if CSI-RS resources configured for L1-SINR measurements are transmitted at density = 3. In some implementations, this clause may apply if CSI-RS resources configured for interference measurements are mapped 1-to-1 to CSI-RS resources configured for channel measurements with the same periodicity.

[0187] In some implementations, CSI-IM can be a CSI resource configured for interference measurement. In practice, CSI-IM may not be transmitted, but a mode can be specified in the resource element grid, which the UE can use for interference measurement. In other words, the UE may not use the CSI-IM resource for transmission and / or reception, but can use the mode of the CSI-IM resource to measure interference.

[0188] According to some implementation schemes, T is used to determine L1-SINR_Measurement_Period_CSI-RS_CMR_IMR Example table of values ​​in Figure 15 China targets FR1 and Figure 16 The document provides an explanation of FR2.

[0189] In some implementation schemes, for Figure 15 and Figure 16 If the following conditions are met, then M=1 can be applied:

[0190] • The non-periodic NZP-CSI-RS is configured as either a CMR or a dedicated IMR.

[0191] • The non-periodic CSI-IMR is configured as a dedicated IMR.

[0192] • Periodic and semi-persistent NZP-CSI-RS are configured as CMR or dedicated IMR, and the high-level parameters timeRestrictionForChannelMeasurement and / or timeRestrictionForInterferenceMeasurements are configured, and / or

[0193] • Periodic and semi-persistent CSI-IM are configured as dedicated IMRs, and the high-level parameters timeRestrictionForChannelMeasurement and / or timeRestrictionForInterferenceMeasurements are configured.

[0194] In some implementations, M=3 may be applied in other ways, for example, if the condition M=1 does not apply.

[0195] As mentioned above, relative to Figure 15 and Figure 16 Because of the overlap between the L1 measurement, the SMTC used for the L3 measurement, and the measurement gap, P can be a scaling factor. MGRP can be the measurement gap repetition period configured in the MG mode. CSSF inter It can be a scaling factor measured across multiple layers. CSSF inter The parameters can be determined according to the methods described herein (e.g., in conjunction with the number of layers used for inter-frequency L1 measurements between neighboring cells). Any or all of these parameters can be specifically set and / or determined for one or more neighboring cells.

[0196] Similarly, T CSI-RS This can be the periodicity of a CSI-RS configured for L1-SINR measurements, such as for inter-frequency adjacent cell measurements. DRX This can be the DRX loop length. T Report This can be a configuration periodicity used for reporting, such as for inter-frequency adjacent cell measurements.

[0197] It should be understood that the UE can use Figures 7 to 16 The measurement period is determined by one or more of the tables shown in either of the tables (e.g., in 506). For example, based on configuration information provided to the UE (e.g., in 504), the UE may determine the measurement period using one or more of the tables (e.g., ...). Figures 7 to 16 The UE can use one or more of the parameter values ​​used in the relevant table to determine the corresponding measurement period for the application. Therefore, the UE can use the determined measurement period to perform inter-frequency L1 neighboring cell measurements (e.g., in 510). The UE can report the measurements according to the corresponding reporting period (e.g., in 512).

The corresponding UE L1 measurement capabilities and limitations are currently specified in 3GPP TS 38.306 v.16.4.0 and 38.133 v.16.7.0, respectively. For example, UE scheduling availability in conjunction with such measurements (e.g., whether / when a UE can be scheduled to perform data communication before, during, and after performing L1 measurements of the serving cell) can currently be specified in 3GPP TS 38.133 v.16.7.0.
