Abstract

The present disclosure relates to techniques for calibrating wireless device and cellular network expectations and behavior in connection with neighbor cell measurements in a wireless communication system. A wireless device can determine that a reference signal is configured for a neighbor cell measurement, which is also configured with a communication with a serving cell. The wireless device can determine whether the reference signal for the neighbor cell measurement is configured with a same or different subcarrier spacing as the communication with the serving cell. The wireless device can select one or more of the reference signal for the neighbor cell measurement or the communication with the serving cell to receive based at least in part on whether the reference signal for the neighbor cell measurement is configured with the same or different subcarrier spacing as the communication with the serving cell.

Description

Technical Field

[0001] This application relates to wireless communication, and more specifically to systems, apparatus, and methods for calibrating the desired and behavior of wireless devices and cellular networks by incorporating neighboring cell measurements in a wireless communication system. 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. ™ 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—such as wireless devices like 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 transmit and receive capabilities for improved communication. Thus, improvements are expected in this area. Summary of the Invention

[0004] This paper presents implementation schemes for apparatus, systems, and methods for calibrating the expected and behavior of wireless devices and cellular networks in wireless communication systems by incorporating neighboring cell measurements.

[0005] In wireless communication systems, when configuring neighboring cell measurements, setting and adhering to certain configuration expectations or requirements regarding behavior can allow for more efficient and predictable network and wireless device behavior, and can reduce undesirable behavior and waste of network resources and power. Therefore, this document describes techniques for configuring and operating wireless devices according to such expectations and / or requirements.

[0006] According to the techniques described herein, a wireless device can be configured to perform neighboring cell measurements while configuring communication with the serving cell of the wireless device. The wireless device can select to receive one or both of the reference signal configured for neighboring cell measurements or communication with the serving cell based on any one or all of a variety of considerations, and can receive the selected signal accordingly.

[0007] These considerations may include: whether the reference signal configured for neighboring cell measurements is configured with the same or different subcarrier spacing as the communication with the serving cell; the wireless device's simultaneous reception of reference signals for neighboring cell measurements and communication with the serving cell having different subcarrier spacings; the frequency range and / or frequency band of the reference signal configured for neighboring cell measurements and communication with the serving cell; the beam configuration of the reference signal configured for neighboring cell measurements and communication with the serving cell; the type of the reference signal; and / or the type of communication with the serving cell; and various other possible considerations.

[0008] If only the reference signal configured for neighboring cell measurements is selected, and the received timing difference between the reference signal configured for neighboring cell measurements and the communication with the serving cell is sufficiently large, then in at least some cases, the wireless device may not perform (or be expected to perform) communication with the serving cell within a specific time amount (e.g., 1 symbol) before and / or after receiving the reference signal configured for neighboring cell measurements.

[0009] It should be noted that the technologies described herein can be implemented in and / or used in several different types of devices, including but not limited to base stations, access points, mobile phones, portable media players, tablets, wearable devices, unmanned aerial vehicles, unmanned flight controllers, automobiles and / or motor vehicles, and various other computing devices.

[0049] the term

[0050] The following is a glossary of terms that will appear in this disclosure:

[0051] 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.

[0052] 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).

[0053] 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) containing at least one processor that executes instructions from a memory medium.

[0054] 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). ™ Based on Android ™ Phones), tablets (e.g., iPads) ™ Samsung Galaxy ™ ), portable gaming devices (e.g., Nintendo DS) ™ PlayStation Portable ™ Gameboy Advance ™ iPhone ™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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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 perform that action directly. 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.

[0061] "Configured as"—Various components can be described as being "configured 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 switched on. Typically, the circuit forming the structure corresponding to "configured as" can include hardware circuitry.

[0062] 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.

[0063] Figure 1 and Figure 2 -Exemplary communication system

[0064] 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 1 The 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.

[0065] 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.

[0066] 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.

[0067] 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 (LTE-A), LAA / LTE-U, 5G NR, 3GPP2, CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), Wi-Fi, etc.

[0068] 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.

[0069] 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 neighboring cell measurements in a wireless communication system according to techniques used to calibrate the expected and behavior of wireless devices and cellular networks by incorporating neighboring cell measurements, such as the various methods described herein. UE 106 can also be configured, or alternatively configured, to use WLAN, BLUETOOTH, etc. ™ 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.

[0070] 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.

[0071] 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.

[0072] 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 NR, or LTE or GSM), and for communication using Wi-Fi and BLUETOOTH. ™ Each component communicates independently. Other configurations are also possible.

[0073] Figure 3 - Block diagram of an exemplary UE device

[0074] 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.

[0075] 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). ™(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.

[0076] UE 106 may include hardware and software components for implementing a method of performing neighboring cell measurements in a wireless communication system, based on techniques for calibrating the expected and behavioral behavior of wireless devices and cellular networks by incorporating neighboring cell measurements, as further described herein. 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 and / or interoperable with other components, such as… Figure 3 As shown, neighboring cell measurements are performed in a wireless communication system according to various embodiments disclosed herein, based on techniques used to calibrate the expected behavior of wireless devices and cellular networks by incorporating neighboring cell measurements. Processor 302 may also implement various other applications and / or end-user applications running on UE 106.

[0077] 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. ™ 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 ™Controller 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.

[0078] 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.

[0079] Figure 4 - Block diagram of an exemplary base station

[0080] 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 for 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).

[0081] 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).

[0082] 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 some 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.

[0083] Reference signal

[0084] 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 with 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.

[0085] 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).

[0086] 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)).

[0087] 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.

[0088] 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 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.

[0089] 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.

[0090] 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 (×R matrix), and therefore R can be called the "rank indicator (RI)" in this context.

[0091] 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, each layer can be mapped 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 implementations, 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.

[0092] Figure 5 - Combine neighboring cell measurements to calibrate wireless device and cellular network expectations and behaviors

[0093] For example, in addition to performing data and control communications, wireless devices in a cellular communication system can typically perform neighboring cell measurements and serving cell measurements at various times, for example, to ensure consistently good reception and facilitate cell handover and reselection, as well as for various other purposes. Multiple types of signals and channels can exist for various types of measurements and communications with neighboring and serving cells. Furthermore, multiple types of wireless devices can be operating in a given cellular communication system, and these types of wireless devices may have different capabilities.

[0094] Given the variety of possible wireless devices and scenarios that can operate in a given cellular communication system, it may be useful to define at least some expected or required wireless device and / or network behaviors in conjunction with these scenarios, at least in a way that can reduce or avoid wasted network power / resource usage and unintended interference. One such area could include combining wireless device and cellular network expectations and behaviors with neighboring cell measurements.

[0095] To illustrate such a set of possible technologies, Figure 5 This is a flowchart illustrating a method for operating a wireless device in a cellular communication system when neighboring cell measurements are configured according to a framework for calibrating the expectations and behaviors of the wireless device and the cellular network by incorporating neighboring cell measurements, according to at least some embodiments.

[0096] Figure 5 Aspects of the method may be implemented by a wireless device, for example, in conjunction with one or more cellular base stations (such as UE 106 and BS 102 shown and described with respect to the various figures herein), or more generally, in conjunction as needed with any of the computer circuits, systems, devices, elements, or components shown in the aforementioned figures. For example, the processor (and / or other hardware) of such a device may be configured to cause the device to perform any combination of the illustrated method elements and / or other method elements.

[0097] 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.

[0098] In section 502, a wireless device can establish a radio link with a cellular base station. According to some implementations, the radio link may include a 5G NR-based cellular link. For example, the wireless device may establish a session with an AMF entity of the cellular network via one or more gNBs that provide radio access to the cellular network. Alternatively, the radio link may include an LTE-based cellular link. For example, the wireless device may establish a session with a mobility management entity of the cellular network via an eNB that provides radio access to the cellular network. Other types of cellular links are also possible according to various implementations, and the cellular network may also or alternatively operate according to another cellular communication technology (e.g., UMTS, CDMA2000, GSM, etc.).

[0099] Establishing a radio link may include, according to at least some implementations, establishing an RRC connection with a serving cellular base station. Establishing a first RRC connection may include configuring various parameters for communication between the radio device and the cellular base station, establishing environmental information for the radio device, and / or any of various other possible characteristics, such as establishing an air interface for the radio device to communicate with a cellular network associated with the cellular base station. After establishing an RRC connection, the radio device may operate in an RRC connected state. In some instances, the RRC connection may also be released (e.g., after a period of inactivity relative to data communication), in which case the radio device may operate in an RRC idle state or an RRC inactive state. In some cases, such as due to radio device movement, changes in radio medium conditions, and / or any other various possible reasons, the radio device may perform a handover (e.g., when in RRC connected mode) or cell reselection (e.g., when in RRC idle mode or RRC inactive mode) to a new serving cell.

[0100] According to at least some implementations, a wireless device can establish multiple wireless links, for example, with multiple TRPs in a cellular network, based on a multi-TRP configuration. In such scenarios, the wireless device 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 TCI states can be activated at a specific time by the wireless device's Media Access Control (MAC) control element (CE).

[0101] In at least some cases, establishing a wireless link may include the wireless device providing information about its capabilities. This capability information may include information related to any one of a variety of wireless device capabilities.

[0102] In some cases, capability information may include information indicating whether a radio device supports simultaneous reception of reference signals for neighbor cell measurements and communications with the serving cell, both having different parameter sets (e.g., subcarrier spacing). For example, capability information may indicate whether a radio device supports concurrent CSI-RS-based neighbor cell measurements and serving cell PDCCH or PDSCH reception with different subcarrier spacings. Such capability information may indicate one or more different subcarrier spacing combinations for which the radio device supports concurrent CSI-RS-based neighbor cell measurements and serving cell PDCCH or PDSCH reception. Additionally or alternatively, such capability information may indicate whether a radio device supports concurrent CSI-RS-based neighbor cell measurements and serving cell PDCCH or PDSCH reception with different subcarrier spacings for one or more of 3GPP Layer 1 (L1) or Layer 3 (L3) neighbor cell measurements. As another possibility, such capability information can indicate whether a wireless device supports concurrent CSI-RS-based neighboring cell measurements and serving cell PDCCH or PDSCH reception with different subcarrier spacings for one or more of intra-frequency or inter-frequency measurements.

[0103] The wireless device may also, or alternatively, provide capability information indicating whether the wireless device supports simultaneous reception of reference signals for neighboring cell measurements and reference signals for serving cell measurements with different parameter sets, for example, for concurrent SSB-based neighboring cell measurements and SSB-based serving cell measurements with different subcarrier spacings, and / or for concurrent CSI-RS-based neighboring cell measurements and CSI-RS-based serving cell measurements with different subcarrier spacings. Capability information may also, or alternatively, be provided by the wireless device to indicate whether the wireless device supports concurrent SSB-based neighboring cell measurements and serving cell PDCCH or PDSCH reception with different subcarrier spacings. Any level of granularity or specificity may be provided for any or all such capability indications, such as whether the support applies to 3GPP L1 and / or 3GPP L3 neighboring cell measurements with regard to one or more different combinations of supported or unsupported subcarrier spacings, and / or whether the support applies to intra-frequency measurements and / or inter-frequency measurements, and various other possibilities.

[0104] In some cases, a wireless device may additionally or alternatively provide capability information to indicate one or more L1 neighbor cell measurement support capabilities of the wireless device. For example, such capabilities may include one or more L1 measurements that the wireless device is capable of performing (e.g., the maximum number of L1 measurements that the wireless device is capable of performing in each of one or more scenarios or sets of conditions, such as for one-port NZP CSI-RS resources and SSB, for two-port NZP CSI-RS resources, for non-periodic CSI-RS resources, etc.). Depending on various embodiments, such capability information may be provided as combined capability information for L1 neighbor cell measurements and serving cell measurements, or it may be provided as L1 neighbor cell measurement-specific capability information.

[0105] In 504, the wireless device can determine that a reference signal is configured for neighboring cell measurements, and communication with the serving cell is also configured. The reference signal can be any of various types of reference signals, and communication with the serving cell can include any of various types of communication.

[0106] As one possibility, the reference signal may include a reference signal configured for L1 or L3 neighbor cell measurements. For example, the configured reference signal may include a CSI-RS for L1 reference signal received power (RSRP), a CSI-RS for L1 signal-to-interference-plus-noise ratio (SINR), a CSI-RS for L3, an SSB for L1-RSRP, an SSB for L1-SINR, or an SSB for L3, and various other possibilities.

[0107] In some cases, communication with the serving cell may include one or more of control or data communications, such as PDCCH transmissions and / or PDSCH transmissions. As another possibility, communication with the serving cell may include reference signals configured for cell measurements and / or one or more other purposes, such as CSI-RS or SSB. For example, communication with the serving cell may include CSI-RS or SSB from the serving cell configured for Radio Link Monitoring (RLM), Beam Failure Detection (BFD), Candidate Beam Detection (CBD), or L1-RSRP measurements, and various other possibilities.

[0108] In clause 506, the wireless device can determine whether a reference signal used for neighboring cell measurements is configured with the same or different subcarrier spacing as communication with the serving cell. In at least some cases, this may include determining the subcarrier spacing of each cell, and determining whether the determined subcarrier spacing is the same or different. The wireless device can determine the subcarrier spacing of each cell in any of a variety of possible ways. For example, such determination may be based on system acquisition and / or system information associated with each cell, dedicated configuration information provided to the wireless device (e.g., provided via RRC), reference signal and / or channel type, implicit determination (e.g., based on cellular communication standard specifications, cell frequency range, cell carrier, other cell characteristics, etc.), and various other possibilities. In some cases, if the reference signal used for neighboring cell measurements is configured with a different subcarrier spacing than communication with the serving cell, the wireless device can also determine the combination of the reference signal configured for neighboring cell measurements and the subcarrier spacing configured for communication with the serving cell. For example, if a wireless device has the capability to perform concurrent neighbor cell measurements and serving cell communications with different parameter sets for some subcarrier spacing combinations but not others, the wireless device can determine whether it supports the reference signal configured for neighbor cell measurements and the subcarrier spacing combination for communication with the serving cell.

[0109] In 508, a wireless device may choose to receive one or more of the following: a reference signal used for neighboring cell measurements or communications with the serving cell. The wireless device may receive the selected signal and discard (e.g., not receive / transmit) any unselected signal. At least according to some embodiments, the selection may be performed according to cellular communication standard specifications for desired or required wireless device behavior, and the cellular base station serving the wireless device may accordingly expect the selection made by the wireless device.

[0110] According to at least some implementations, this selection can be based, at least in part, on whether the reference signal used for neighboring cell measurements is configured with the same or different subcarrier spacing as the communication with the serving cell. For example, in some cases, if the reference signal used for neighboring cell measurements and the communication with the serving cell are in 3GPP frequency range 1 (FR1), and if the reference signal used for neighboring cell measurements is configured with the same subcarrier spacing as the communication with the serving cell, then both the reference signal used for neighboring cell measurements and the communication with the serving cell can be selected.

[0111] In some cases, this selection may be further based, at least in part, on the ability of the wireless device to simultaneously receive signals with different sets of parameters. For example, in FR1, if the reference signal used for neighboring cell measurements is configured with a different subcarrier spacing than the communication with the serving cell, and the wireless device supports simultaneously receiving both the reference signal used for neighboring cell measurements and the communication with the serving cell with different subcarrier spacings (e.g., including, for a particular combination of subcarrier spacings, the type of reference signal configured for neighboring cell measurements and the type of communication with the serving cell), then the wireless device selects to receive both the reference signal used for neighboring cell measurements and the communication with the serving cell. However, if the wireless device does not support simultaneously receiving both the reference signal used for neighboring cell measurements and the communication with the serving cell with different subcarrier spacings (e.g., at least for a particular combination of subcarrier spacings, the type of reference signal configured for neighboring cell measurements and / or the type of communication with the serving cell), then it is possible that the wireless device selects to receive only one of the reference signal used for neighboring cell measurements or the communication with the serving cell. Which one is selected may depend at least in part on the type and / or characteristics of the reference signal configured for neighboring cell measurements and the communication with the serving cell. For example, in some cases, neighboring cell measurements may take precedence over some or all data and control communications (e.g., PUSCH, PUCCH, PDCCH, and PDSCH transmissions). It is also possible that in some cases, such as for SSB and CORESET used for Residual Minimum System Information (RMSI) scheduling multiplexing modes 2 and 3, serving cell communications may be configured to take precedence over neighboring cell measurements (e.g., exceptions). For scenarios where communications with the serving cell include at least some reference signals configured for serving cell measurements, it is possible that the radio device may (e.g., with equal priority) select either neighboring cell measurements or serving cell measurements (e.g., for SSB or CSI-RS of RLM, BFD, CBD, or L1-RSRP, as some possibilities).

[0112] It should be noted that if a wireless device selects only the reference signal used for neighbor cell measurements to receive during one or more Orthogonal Frequency Division Multiplexing (OFDM) symbols, and also discards communication with the serving cell during those OFDM symbols, the wireless device may discard communication with the serving cell in at least one OFDM symbol before and / or after those OFDM symbols if the received timing difference between the reference signal used for neighbor cell measurements and the communication with the serving cell is greater than a certain threshold (e.g., the length of the cyclic prefix of the active bandwidth portion). Discarding such symbols can help support the wireless capabilities of the wireless device to switch communication links between different subcarrier intervals and / or relative to other communication link configuration settings.

[0113] In some cases (e.g., if the reference signal used for neighboring cell measurements and the communication with the serving cell are in 3GPP frequency range 2 (FR2), as a possibility), the radio device can determine whether the reference signal used for neighboring cell measurements is configured with the same or different beam configuration as the communication with the serving cell, and can select one or more of the reference signal used for neighboring cell measurements or the communication with the serving cell to receive, at least in part, based on whether the reference signal used for neighboring cell measurements is configured with the same or different beam configuration as the communication with the serving cell. For example, in some cases (e.g., in FR2, if the serving cell and the neighboring cell are in the same frequency band, as a possibility), if different beams are configured for the reference signal used for neighboring cell measurements and the communication with the serving cell (e.g., if they are not quasi-cooperative positioning (QCL)), the radio device may not be able to receive the reference signal used for neighboring cell measurements and the communication with the serving cell simultaneously, even using the same set of parameters. In some implementations, the network can provide signaling information to indicate the QCL information of the neighboring cell's SSB / CSI-RS relative to the serving cell (if applicable). The radio device can use this QCL information to determine whether the reference signal used for neighboring cell measurements is configured with the same or a different beam configuration as the communication with the serving cell. In FR2, if the reference signal used for neighboring cell measurements is configured with a different beam configuration than the communication with the serving cell, or if the radio device cannot determine whether the neighboring cell measurements are configured with the same or a different beam configuration as the communication with the serving cell, it is possible that the radio device will select only one of the reference signal used for neighboring cell measurements or the communication with the serving cell to receive.

[0114] It should also be noted that, at least in some cases, the selection of one or more of the reference signal used for neighboring cell measurements or the communication with the serving cell for reception may be at least partially based on whether the reference signal used for neighboring cell measurements is configured in the same or a different frequency band as the communication with the serving cell. For example, when the wireless device is capable of independent beam management (IBM), any in-band scheduling restrictions may not apply for inter-band carrier aggregation in FR1 and / or inter-band carrier aggregation in FR2. Therefore, even if the wireless device selects only one of the reference signal used for neighboring cell measurements or the communication with the serving cell for reception in one frequency band, the wireless device may still be able to simultaneously receive communication on the serving cell in other frequency bands (e.g., where the reference signal used for neighboring cell measurements is not configured), for example, provided that the wireless device would otherwise be capable of performing simultaneous reception on multiple frequency bands.

[0115] Therefore, at least in some cases, at least according to some implementation schemes, Figure 5The method can be used to calibrate the expectations between the wireless device and the cellular base station regarding the signal received by the wireless device in a manner that helps support reduced wireless device complexity and power consumption and / or reduced network power and / or resource waste, when neighboring cell measurements and serving cell communications are configured simultaneously.

[0116] Additional Information

[0117] The following additional information describes what can be combined if needed. Figure 5 Other aspects of the method used. However, it should be noted that the exemplary details described are not intended to limit this disclosure as a whole: many variations and alternative forms of the details provided below are possible and should be considered within the scope of this disclosure.

[0118] In 3GPP Releases 15 and 16, L1 measurements on the serving cell, including L1-RSRP and L1-SINR measurements, are supported. The corresponding UE L1 measurement capabilities and limitations can currently be 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 for data communication before, during, and after performing L1 measurements on the serving cell) can currently be specified in 3GPP TS 38.133 v.16.7.0.

[0119] L1 measurements on neighboring cells are not supported in 3GPP Releases 15 and 16, but are supported in 3GPP Release 17. Therefore, providing a framework for combining such L1 measurements on neighboring cells to determine UE scheduling availability may be useful, for example, to avoid unnecessary network power and / or resource usage, to avoid accidental interference, and / or for any of other possible reasons.

[0120] One possible aspect of this framework could include introducing new UE capability indications related to whether the UE supports simultaneous serving cell PDCCH / PDSCH reception and neighboring cell CSI-RS measurements with different subcarrier spacings. This capability information can be designed in any of a variety of ways, for example, to include more or less information at any of a range of granular levels.

[0121] For example, as an option, a single-bit capability indicator (e.g., “simultaneousRxDataCSI-RS-DiffNumerology”) can be defined and used to indicate whether the UE supports concurrent CSI-RS-based measurements with different parameter sets on neighboring cells and reception from the serving cell’s PDCCH or PDSCH.

[0122] As an alternative, the capability indicator can be split into two bits (e.g., “simultaneousRxDataL1CSI-RS-DiffNumerology” and “simultaneousRxDataL1CSI-RS-DiffNumerology”) to indicate whether the UE supports concurrent CSI-RS-based L1 and L3 measurements with different parameter sets on neighboring cells, as well as reception from the serving cell’s PDCCH or PDSCH.

[0123] As an alternative, two single-bit capability indicators can be defined (e.g., “simultaneousRxDataCSI-RS-DiffNumerology-intra” and “simultaneousRxDataCSI-RS-DiffNumerology-inter”), and these two single-bit capability indicators can be used to support concurrent CSI-RS-based measurements with different parameter sets on neighboring cells, respectively for intra-frequency measurements and inter-frequency measurements, as well as UE capability reports received from the serving cell's PDCCH or PDSCH. It should be noted that in such a scenario, a UE indicating support for inter-frequency measurements with different parameter sets can be reporting support for CSI-RS-based inter-frequency measurements without measurement gaps.

[0124] As another option, each such capability indicator can be split into two bits, for example, to distinguish support for concurrent CSI-RS-based L1 and L3 measurements with different parameter sets on neighboring cells, as well as support for PDCCH or PDSCH received from the serving cell for each of intra-frequency and inter-frequency measurements.

[0125] In some cases, any of the previously described options for reporting CSI-RS-based measurements on neighboring cells with different parameter sets that support concurrency, as well as UE capabilities received from the serving cell's PDCCH or PDSCH, can be further divided into multiple bits to indicate support for different combinations of parameter sets. For example, when reporting such capability information such as any or all of the following, the UE can indicate a range of supported parameter set combinations: {15kHz to 30kHz; 15kHz to 60kHz; 15kHz to 120kHz; 30kHz to 60kHz; 30kHz to 120kHz; 60kHz to 120kHz}, and various other possibilities.

[0126] It should be noted that, at least in some cases, the adjacent L1 measurements described herein may include any or all L1-RSRP measurements and / or L1-SINR measurements based on adjacent SSBs and / or CSI-RS.

[0127] Regardless of whether or how CSI-RS-based measurements with different parameter sets on neighboring cells are configured to support concurrency, and UE capability reports received from the serving cell's PDCCH or PDSCH, at least according to some implementations, it may be useful to provide a framework that may determine the scheduling availability of the UE during neighboring cell L1 measurements.

[0128] According to one possible architecture, in 3GPP frequency range 1 (FR1), it is possible that if a reference signal (e.g., SSB or CSI-RS) configured for L1 measurement from a neighboring cell has the same SCS as the PDCCH / PDSCH in the active bandwidth portion of the serving cell, there are no scheduling restrictions due to neighboring cell L1 measurement. Therefore, in such a scenario, the serving cell may schedule the UE to receive PDCCH / PDSCH simultaneously with the configured neighboring cell L1 measurement.

[0129] If there is an SSB from a neighboring cell configured for L1 measurements that has a different SCS than the PDCCH / PDSCH in the active BWP of the serving cell in FR1, it is possible that for UEs that support (e.g., including reporting as a UE capability) simultaneousRxDataSSB-DiffNumerology, there are no scheduling restrictions because neighboring cell L1 measurements use the SSB as the RS.

[0130] For UEs that do not support simultaneousRxDataSSB-DiffNumerology, due to L1 measurements, the serving cell and UE may impose certain constraints and / or assumptions on UE scheduling availability based on the neighboring cell SSBs configured for L1 measurements. For example, it may not be expected that such a UE transmits PUCCH / PUSCH / SRS on symbols corresponding to the neighboring cell SSB index configured for L1 measurements, or receives PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI. If the received timing difference (RTD) between the neighboring cell SSB configured for L1 measurements and the serving cell PDCCH / PDSCH / CSI-RS exceeds the cyclic prefix (CP) length of the active BWP, it may be expected that the UE transmits PUCCH / PUSCH / SRS on one data symbol before each consecutive SSB symbol to be measured and one data symbol after each consecutive SSB symbol to be measured, or receives PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI.

[0131] It should be noted that when configuring intra-band carrier aggregation in FR1, any scheduling restrictions on the serving cell based on SSB-based neighboring L1 measurements on symbols that fully or partially overlap with the restricted symbols may apply to all serving cells in the same frequency band. When configuring inter-band carrier aggregation within FR1, it is possible that there are no scheduling restrictions on FR1 serving cells configured in frequency bands other than those where the serving cell scheduling availability is limited due to neighboring L1 measurements.

[0132] If a CSI-RS configured for L1 measurement exists from a neighboring cell, having an SCS different from the PDCCH / PDSCH in the active BWP of the serving cell in FR1, it is possible that the UE is not expected to transmit PUCCH / PUSCH / SRS on symbols corresponding to the neighboring cell CSI-RS index configured for L1 measurement, or receive PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI. Additionally, in some cases, if the RTD between the neighboring cell CSI-RS configured for L1 measurement and the serving cell PDCCH / PDSCH / CSI-RS exceeds the CP length of the active BWP, it is possible that the UE is not expected to transmit PUCCH / PUSCH / SRS on one data symbol before each consecutive CSI-RS symbol to be measured and one data symbol after each consecutive CSI-RS symbol to be measured, or receive PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI. As an alternative, this approach can be used if the simultaneousRxDataCSI-RS-DiffNumerology capability is not defined.

[0133] As another possibility, it's possible that for UEs supporting (e.g., including reporting as a UE capability) simultaneousRxDataCSI-RS-DiffNumerology, there are no scheduling restrictions because neighboring cell L1 measurements use CSI-RS as the RS. In some cases, the lack of scheduling restrictions in such scenarios may depend on the specific simultaneousRxDataCSI-RS-DiffNumerology report for the UE being applicable to existing scenarios, for example, considering the specific different SCS combinations used for neighboring cell L1 measurements and serving cell PDCCH / PDSCH, such as in the case of configuring more granular capability reporting relative to support for different SCS combinations.

[0134] For UEs that do not support simultaneousRxDataCSI-RS-DiffNumerology, due to L1 measurements, the serving cell and UE may impose certain constraints and / or assumptions on UE scheduling availability based on the neighboring cell CSI-RS configured for L1 measurements. For example, it may not be expected that such a UE will transmit PUCCH / PUSCH / SRS on symbols corresponding to the neighboring cell CSI-RS configured for L1 measurements, or receive PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI. If the RTD between the neighboring cell CSI-RS configured for L1 measurements and the serving cell PDCCH / PDSCH / CSI-RS exceeds the CP length of the active BWP, it may be expected that the UE will not transmit PUCCH / PUSCH / SRS on one data symbol before each consecutive CSI-RS symbol to be measured and one data symbol after each consecutive CSI-RS symbol to be measured, or receive PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI.

[0135] It should be noted that when configuring intra-band carrier aggregation in FR1, any scheduling restrictions on the serving cell based on CSI-RS-based neighboring L1 measurements on symbols that fully or partially overlap with the restricted symbols may apply to all serving cells in the same frequency band. When configuring inter-band carrier aggregation within FR1, it is possible that there are no scheduling restrictions on FR1 serving cells configured in frequency bands other than those where the serving cell scheduling availability is limited due to neighboring L1 measurements.

[0136] According to some implementation schemes, different frameworks for determining UE scheduling availability during neighboring cell L1 measurements may be used in 3GPP Frequency Range 2 (FR2) instead of FR1, for example because FR2 may have increased requirements / use of beamforming compared to FR1. For example, according to one possible architecture, it is possible that the UE is not expected to transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI on one or more of the following: symbols corresponding to SSB indices configured for neighboring cell L1 measurements; symbols corresponding to periodic CSI-RS resources configured for neighboring cell L1 measurements; symbols corresponding to semi-persistent CSI-RS resources configured for neighboring cell L1 measurements when such resources are activated; or symbols corresponding to non-periodic CSI-RS resources configured for neighboring cell L1 measurements when a report is triggered. If the RTD between the neighboring cell SSB or CSI-RS configured for L1 measurement and the serving cell PDCCH / PDSCH / CSI-RS exceeds the CP length of the active BWP, it is possible that the UE is not expected to transmit PUCCH / PUSCH / SRS on one data symbol before each consecutive SSB or CSI-RS symbol to be measured and one data symbol after each consecutive SSB or CSI-RS symbol to be measured, or to receive PDCCH / PDSCH / CSI-RS for tracking / CSI-RS for CQI.

[0137] As another possibility, in some cases, new signaling may be introduced to allow the network to indicate QCL information from the neighboring cell's SSB / CSI-RS to the serving cell's SSB / CSI-RS (e.g., the neighboring cell's SSB TRS may be the same as the serving cell's SSB TRS). In such a scenario, if the RS from the neighboring cell used for L1 measurements has the same active TCI state QCL as the serving cell's PDCCH / PDSCH, and is not in a CSI-RS resource set with repeated activation, and receive beam scanning is not required for the measurement (e.g., N=1 applies, as specified in Section 9.5.4.2 of 3GPP TS 38.133 v.16.7.0), then it is possible that there are no scheduling constraints due to L1 measurements performed based on the RS from the neighboring cell.

[0138] When performing in-band carrier aggregation in FR2, it is possible that the scheduling of serving cells performing neighboring cell L1 measurements is restricted to symbols that fully or partially overlap with the restricted symbols, applicable to all serving cells in the same frequency band.

[0139] When performing inter-band carrier aggregation in FR2, it is possible that there are no scheduling restrictions on the FR2 serving cell in a different frequency band than the FR2 serving cell which has scheduling restrictions due to L1 measurements of neighboring cells, provided that the UE has independent beam management (IBM) capability on this FR2 band pair. Alternatively, it is possible that if the UE has different parameter sets configured between the SSB or CSI-RS on one FR2 band and the data on another FR2 band, there are no scheduling restrictions, provided that the UE is configured with IBM operation for the band pair.

[0140] It should be noted that within this framework, there may be some exceptions to the scheduling restrictions on the serving cell caused by adjacent L1 measurements. For example, as one possibility, if the UE has already been notified of system information updates (e.g., via paging information), and for SSBs and CORESETs used in RMSI scheduling multiplexing mode 3, the gap between the PDCCH monitored by the UE in the type 2 PDCCH CSS set and including the system information update notification, and the PDCCH monitored by the UE in the type 0 PDCCH CSS set is greater than two time slots, then it can be expected that the UE will receive the PDCCH and corresponding PDSCH monitored by the UE in the type 0 PDCCH CSS set on the SSB symbol to be measured for L1 measurement. In such a scenario, for SSBs and CORESETs used in RMSI scheduling multiplexing mode 2, it can also be or alternatively expected that the UE will receive the PDSCH corresponding to the PDCCH monitored by the UE in the type 0 PDCCH CSS set on the SSB symbol to be measured for L1 measurement.

[0141] It should also be noted that, if necessary, a similar framework can be used to configure scheduling restrictions by combining neighboring cell L3 measurements with different SCSs. For example, as previously described, at least in some cases, UE capability information can be supported to indicate whether simultaneous serving cell control / data communications and neighboring cell CSI-RS L3 measurements with different SCSs are supported. The UE and network can use such information according to a similar framework described earlier herein to determine whether the UE is expected to receive both serving cell control / data communications and neighboring cell CSI-RS L3 measurements with different SCSs when both are scheduled simultaneously, or whether the UE is expected not to receive one or more such communications in such a scenario.

[0142] According to at least some implementations, in addition to calibrating the scheduling availability expectations of the UE when configuring neighboring cell L1 measurements, or alternatively, it may be useful to provide a framework for calibrating the expectations of UE behavior when configuring serving cell measurements and neighboring cell L1 measurements.

[0143] According to at least some implementations, 3GPP TS 38.306 v16.4.0 specifies existing UE capabilities regarding support for a maximum number of L1 measurements in the beamManagementSSB-CSI-RS information element (IE). Currently, this beamManagementSSB-CSI-RS can be defined specifically for the serving cell. Therefore, it may be useful to provide a new way of reporting UE capabilities for indicating support for a maximum number of L1 measurements on neighboring cells, for example, allowing the UE to disregard the corresponding measurement requirements if the actual number of configured resources exceeds the indicated UE capability, and without defining UE behavior.

[0144] As one possibility for providing a mechanism for such UE capability reporting, a new UE capability IE can be defined, which can be used to indicate the maximum number of L1 measurements supported by the UE on neighboring cells. At least according to some implementations, the following example can be used as a possible design for such a “neighborCellBeamManagementSSB-CSI-RS” IE.

[0145] neighborCellBeamManagementSSB-CSI-RS

[0146] Defines support for RSRP measurements based on SS / PBCH and CSI-RS on neighboring cells. This capability includes sending signal notifications for the following:

[0147] -maxNumberSSB-CSI-RS-ResourceOneTx indicates the maximum total number of port NZP CSI-RS resources and SS / PBCH blocks supported by the UE within a time slot and across all adjacent cells as specified in TS 38.215

[13] (see note).

[0148] -maxNumberCSI-RS-Resource indicates the maximum total number of NZP-CSI-RS resources supported by the UE across all neighboring cells as specified in TS 38.215

[13] for the measurement L1-RSRP (see note).

[0149] -maxNumberCSI-RS-ResourceTwoTx indicates the maximum total number of port NZP CSI-RS resources supported by the UE within a time slot and across all adjacent cells as specified in TS 38.215

[13] (see note).

[0150] -supportedCSI-RS-Density indicates the density of one RE per PRB for a port NZP CSI-RS resource used for RSRP reporting (if supported).

[0151] -maxNumberAperiodicCSI-RS-Resource indicates the maximum number of configured aperiodic CSI-RS resources across all neighboring cells (see note).

[0152] Note: If the UE sets a value different from n0 in the FR1 band, it will set the same value in all FR1 bands. If the UE sets a value different from n0 in the FR2 band, it will set the same value in all FR2 bands. The total number of resources supported by the UE is equal to the maximum of the FR1 and FR2 values, but not greater than the FR1 value across all FR1 serving cells, and not greater than the FR2 value across all FR2 serving cells.

[0153] It should be noted that such an IE may include only a subset of the exemplary components described herein, and / or may include other components, among various other possibilities. It should also be noted that this UE capability may be defined by frequency band if required.

[0154] As another possibility, the current beamManagementSSB-CSI-RS UE capability IE could be redefined to cover both the serving cell and neighboring cells. At least according to some implementations, the following example could serve as a possible design for such a “beamManagementSSB-CSI-RS-r17” IE.

[0155] beamManagementSSB-CSI-RS

[0156] Defines support for RSRP measurements based on SS / PBCH and CSI-RS. This capability includes sending signals to notify the following:

[0157] -maxNumberSSB-CSI-RS-ResourceOneTx indicates the maximum total number of port NZP CSI-RS resources and SS / PBCH blocks configured for the L1-RSRP measurement specified in TS 38.215

[13] supported by the UE within the time slot and across all serving cells and neighboring cells (see note). On FR2, mandatory reports >= 8; on FR1, capability signaling mandatory reports >= 8.

[0158] -maxNumberCSI-RS-Resource indicates the maximum total number of NZP-CSI-RS resources that the UE supports across all serving cells and neighboring cells as specified in TS38.215

[13] for the measurement L1-RSRP (see note). For FR1, a minimum of n8 is mandatory.

[0159] -maxNumberCSI-RS-ResourceTwoTx indicates the maximum total number of port NZP CSI-RS resources supported by the UE within a time slot and across all serving cells and neighboring cells as specified in TS 38.215

[13] (see note).

[0160] -supportedCSI-RS-Density indicates the density of one RE per PRB for a port NZP CSI-RS resource used for RSRP reporting (if supported). On FR2, reporting of either "three" or "oneAndThree" is mandatory; on FR1, capability signaling reporting of either "three" or "oneAndThree" is mandatory.

[0161] -maxNumberAperiodicCSI-RS-Resource indicates the maximum number of configured aperiodic CSI-RS resources across all serving cells and neighboring cells (see note). For FR1 and FR2, the UE is required to report at least n4.

[0162] Note: If the UE sets a value different from n0 in the FR1 band, it will set the same value in all FR1 bands. If the UE sets a value different from n0 in the FR2 band, it will set the same value in all FR2 bands. The total number of resources supported by the UE is equal to the maximum of the FR1 and FR2 values, but not greater than the FR1 value across all FR1 serving cells, and not greater than the FR2 value across all FR2 serving cells.

[0163] It should be noted that such an IE may include only a subset of the exemplary components described herein, and / or may include other components, among various other possibilities. It should also be noted that such UE capabilities can be defined by frequency band if desired. In various implementations, for one or more such IE components, a minimum UE capability reporting value different from that provided in the examples may be mandated.

[0164] For FR1, when the SSB configured for L1-RSRP measurement from a neighboring cell and the CSI-RS configured for Radio Link Monitoring (RLM), Beam Failure Detection (BFD), Candidate Beam Detection (CBD), or L1-RSRP measurement from the serving cell are in the same OFDM symbol, if the SSB and CSI-RS have the same SCS, it is possible that, at least according to some implementations, the UE can measure the SSB for L1-RSRP measurement without any restrictions. If the SSB and CSI-RS have different SCS, if the UE supports simultaneousRxDataSSB-DiffNumerology, it is possible that the UE can measure the SSB for L1-RSRP measurement without any restrictions. If the UE does not support simultaneousRxDataSSB-DiffNumerology, it is possible that the UE is required or expected to measure one of the SSB and CSI-RS for L1-RSRP measurement, but not both. For SSB-based L1-RSRP measurements, longer measurement cycles can be expected, and in at least some cases, no requirements need to be defined.

[0165] For FR1, when an SSB from a neighboring cell configured for L1-RSRP measurement and an SSB from the serving cell configured for RLM, BFD, CBD, or L1-RSRP measurement are in the same OFDM symbol, if the SSB from the neighboring cell and the SSB from the serving cell have the same SCS, it is possible, at least according to some embodiments, that the UE can measure the SSB from both the serving cell and the neighboring cell without any restrictions. If the SSB from the neighboring cell and the SSB from the serving cell have different SCSs, several possible options exist. As one possibility, if a gap is provided for L1 RSRP measurement based on the neighboring cell SSB, it can be expected that the UE measures the neighboring cell SSB during the measurement gap. As another option, it can be expected or required that the UE measure only one of the SSBs without measuring both SSBs, and a longer measurement period is expected. As another option, new UE capabilities can be introduced to indicate support for simultaneous measurement on SSBs with different SCSs, for example, such that, at least according to some embodiments, a UE with this capability can measure the SSB from both the serving cell and the neighboring cell without any restrictions. As another option, it is possible that this configuration with an SSB from a neighboring cell and an SSB from the serving cell with different SCSs is discouraged, and no UE measurement requirements are defined for this scenario.

[0166] For FR2, when the SSB from a neighboring cell used for L1-RSRP measurements on one component carrier (CC) and the CSI-RS or SSB from the serving cell used for RLM, BFD, CBD, or L1-RSRP measurements on different CCs in the same CC or the same frequency band are in the same OFDM symbol, it is possible that the UE is expected or required to measure one of the SSB and CSI-RS used for L1-RSRP measurements, rather than both. For SSB-based L1-RSRP measurements, longer measurement periods can be expected, and in at least some cases, no requirements may be defined. For UEs capable of performing IBM on FR2 band pairs, it is possible that the network does not configure measurement restrictions when configuring a mixed parameter set between the SSB from a neighboring cell used for L1-RSRP measurements on one FR2 band and the CSI-RS or SSB from the serving cell used for RLM, BFD, CBD, L1-RSRP, or L1-SINR measurements on another FR2 band.

[0167] For FR1, when an SSB from the serving cell configured for RLM, BFD, CBD, or L1-RSRP measurements is within an active BWP and has the same SCS as a CSI-RS from a neighboring cell in the same OFDM symbol configured for L1-RSRP measurements, it is possible, at least according to some implementations, that the UE can perform CSI-RS measurements without any restrictions. If, in such a scenario, the SSB from the serving cell and the CSI-RS from the neighboring cell have different SCSs, it is possible, if the UE supports simultaneousRxDataSSB-DiffNumerology, that the UE can perform CSI-RS measurements without any restrictions. If the UE does not support simultaneousRxDataSSB-DiffNumerology, it is possible that the UE is required or expected to measure either the CSI-RS or the SSB used for L1-RSRP measurements, but not both. For CSI-RS-based L1-RSRP measurements, longer measurement periods can be expected, and at least in some cases, no requirements may be defined.

[0168] For FR1, when a CSI-RS from a neighboring cell configured for L1-RSRP measurement and another CSI-RS from the serving cell configured for RLM, BFD, CBD, or L1-RSRP measurement are in the same OFDM symbol, if the two CSI-RS have the same SCS, then at least according to some embodiments, the UE can perform two CSI-RS measurements without any restrictions. If the CSI-RS from the neighboring cell and the CSI-RS from the serving cell have different SCS, several possible options exist. As one possibility, if a gap is provided for L1 RSRP measurement based on neighboring cell CSI-RS, it can be expected that the UE measures the neighboring cell CSI-RS during the measurement gap. As another option, it can be expected or required that the UE measure only one of the CSI-RS without measuring both, and a longer measurement period is expected. As another option, new UE capabilities can be introduced to indicate support for simultaneous measurement on CSI-RS with different SCS, for example, such that, at least according to some embodiments, a UE with this capability can measure CSI-RS from both the serving cell and the neighboring cell without any restrictions. As another option, it is possible that this configuration with CSI-RS from neighboring cells and CSI-RS from the serving cell having different SCS is discouraged, and UE measurement requirements are not defined for this scenario.

[0169] For FR2, when the CSI-RS from a neighboring cell for L1-RSRP measurements on one CC is in the same OFDM symbol as the SSB from the serving cell for RLM, BFD, or L1-RSRP measurements on different CCs in the same CC or the same frequency band, or when a beam failure is detected, it is possible that the UE is expected or required to measure either the CSI-RS or the SSB used for L1-RSRP measurements, but not both. For CSI-RS-based L1-RSRP measurements, longer measurement periods can be expected, and in at least some cases, no requirements may be defined. When a CSI-RS from a neighboring cell used for L1-RSRP measurements on a single CC and another CSI-RS from the serving cell used for RLM, BFD, CBD, or L1-RSRP measurements on different CCs within the same CC or the same frequency band are in the same OFDM symbol, in at least several scenarios, it may be required or expected that the UE measures one of the CSI-RS used for L1-RSRP measurements and the other CSI-RS, rather than both. In such cases, a longer measurement period may be expected for CSI-RS-based L1-RSRP measurements, and in at least some cases, no requirements may be defined. Such scenarios may include: if the CSI-RS from a neighboring cell used for L1-RSRP measurements or another CSI-RS from the serving cell is in a resource set configured with repeated activation; if the CSI-RS from the serving cell is configured in q1 and beam failure is detected; or if both CSI-RS resources are not QCL-compliant with QCL-TypeD; or if the QCL information is unknown to the UE. Exceptions may be specified additionally or alternatively if necessary. Unless there are exceptional configuration circumstances, at least according to some implementation schemes, the UE may be required or expected to be able to measure CSI-RS from neighboring cells for L1-RSRP measurements without any restrictions.

[0170] For FR1, when the SSB of the Channel Measurement Resource (CMR) configured for L1-SINR measurement from a neighboring cell and the CSI-RS from the serving cell for RLM, BFD, CBD, or L1-RSRP measurement are in the same OFDM symbol, if the SSB and CSI-RS have the same SCS, then, at least according to some implementations, it is possible that the UE can measure the SSB for L1-SINR measurement without any restrictions. If the SSB and CSI-RS have different SCS, and if the UE supports simultaneousRxDataSSB-DiffNumerology, then it is possible that the UE can measure the SSB for L1-SINR measurement without any restrictions. If the UE does not support simultaneousRxDataSSB-DiffNumerology, then it is possible that the UE is required or expected to measure one of the SSB and CSI-RS for L1-SINR measurement, but not both. For SSB-based L1-SINR measurement, a longer measurement period can be expected, and at least in some cases, no requirements may be defined.

[0171] For FR1, when an SSB configured for L1-SINR measurement from a neighboring cell and an SSB configured for RLM, BFD, CBD, or L1-RSRP measurement from the serving cell are in the same OFDM symbol, if the SSBs from the neighboring cell and the serving cell have the same SCS, it is possible, at least according to some implementations, that the UE can measure the SSBs from both the serving cell and the neighboring cell without any limitations. If the SSBs from the neighboring cell and the serving cell have different SCSs, several possible options exist, such as those described earlier in this document regarding scenarios where the SSB configured for L1-RSRP measurement from the neighboring cell and the SSB configured for RLM, BFD, CBD, or L1-RSRP measurement from the serving cell are in the same OFDM symbol. For example, as one possibility, if a gap is provided for L1 RSRP measurement based on the neighboring cell SSB, it can be expected that the UE measures the neighboring cell SSB during the measurement gap. As another option, it can be expected or required that the UE measure only one of the SSBs instead of both, and a longer measurement period is desired. As another option, new UE capabilities could be introduced to indicate support for simultaneous measurements on SSBs with different SCSs, for example, enabling a UE with this capability, at least according to some implementations, to measure SSBs from both the serving cell and neighboring cells without any restrictions. As yet another option, it is possible that such a configuration with SSBs from neighboring cells and SSBs from the serving cell with different SCSs is discouraged, and no UE measurement requirements are defined for this scenario.

[0172] For FR2, when the SSB of a CMR from a neighboring cell configured for L1-SINR measurement on one CC and the CSI-RS from the serving cell configured for RLM, BFD, CBD, or L1-RSRP measurement on different CCs in the same CC or the same frequency band are in the same OFDM symbol, it is possible that the UE is expected or required to measure one of the SSB and CSI-RS used for L1-SINR measurement, rather than both. For SSB-based L1-SINR measurement, a longer measurement period can be expected, and in at least some cases, no requirement may be defined. For UEs capable of performing IBM on FR2 band pairs, it is possible that no measurement restrictions are configured when the network configures a mixed parameter set between the SSB from a neighboring cell configured for L1-SINR measurement on one FR2 band and the CSI-RS from the serving cell configured for RLM, BFD, CBD, L1-RSRP, or L1-SINR measurement on another FR2 band.

[0173] For FR1, when an SSB from the serving cell configured for RLM, BFD, CBD, L1-RSRP, or L1-SINR measurement is within an active BWP and has the same SCS as a CSI-RS from a neighboring cell in the same OFDM symbol configured for L1-SINR measurement, it is possible, at least according to some implementations, that the UE can perform CSI-RS measurements without any restrictions. If, in such a scenario, the SSB from the serving cell and the CSI-RS from the neighboring cell have different SCSs, it is possible, if the UE supports simultaneousRxDataSSB-DiffNumerology, that the UE can perform CSI-RS measurements without any restrictions. If the UE does not support simultaneousRxDataSSB-DiffNumerology, it is possible that the UE is required or expected to measure either the CSI-RS or the SSB used for L1-SINR measurement, but not both. For CSI-RS-based L1-SINR measurements, longer measurement periods can be expected, and at least in some cases, no requirements may be defined.

[0174] For FR1, when a CSI-RS from a neighboring cell configured for L1-SINR measurement and another CSI-RS from the serving cell configured for RLM, BFD, CBD, or L1-RSRP measurement are in the same OFDM symbol, if the two CSI-RS have the same SCS, then, at least according to some implementations, the UE can perform two CSI-RS measurements without any restrictions. If the CSI-RS from the neighboring cell and the CSI-RS from the serving cell have different SCS, several possible options exist, such as those described earlier in this document regarding scenarios where a CSI-RS from a neighboring cell configured for L1-RSRP measurement and a CSI-RS from the serving cell configured for RLM, BFD, CBD, or L1-RSRP measurement are in the same OFDM symbol. For example, as a possibility, if a gap is provided for L1-SINR measurement based on neighboring cell CSI-RS, it can be expected that the UE measures the neighboring cell CSI-RS during the measurement gap. As another option, it may be expected or required that the UE measure only one of the CSI-RSs and not both, with a longer measurement period expected. Alternatively, new UE capabilities may be introduced to indicate support for simultaneous measurement on CSI-RSs with different SCSs, for example, enabling a UE with this capability, at least according to some implementations, to measure CSI-RSs from both the serving cell and neighboring cells without any limitations. Yet another option is that such a configuration with CSI-RSs from neighboring cells and CSI-RSs from the serving cell with different SCSs may be discouraged, and no UE measurement requirements may be defined for this scenario.

[0175] For FR2, when a CSI-RS from a neighboring cell for L1-SINR measurement on one CC is in the same OFDM symbol as an SSB from the serving cell for RLM, BFD, L1-RSRP, or L1-SINR measurement on different CCs in the same CC or the same frequency band, or when a beam failure is detected, it is possible that the UE is expected or required to measure either the CSI-RS or the SSB used for L1-SINR measurement, rather than both. For CSI-RS-based L1-SINR measurement, a longer measurement period can be expected, and in at least some cases, no requirement may be defined. When a CSI-RS from a neighboring cell used for L1-SINR measurement on one CC and another CSI-RS from the serving cell used for RLM, BFD, CBD, L1-RSRP, or L1-SINR measurement on different CCs in the same CC or the same frequency band are in the same OFDM symbol, in at least several scenarios, it is possible that the UE is required or expected to measure one of the CSI-RS used for L1-SINR measurement and the other CSI-RS, rather than both. In such cases, a longer measurement period may be expected for CSI-RS-based L1-SINR measurement, and in at least some cases, no requirement may be defined. Such scenarios may include: if the CSI-RS from the neighboring cell used for L1-SINR measurement or another CSI-RS from the serving cell is in a resource set configured with repeated activation; if the CSI-RS from the serving cell is configured in q1 and beam failure is detected; or if the two CSI-RS resources are not QCL-compliant with QCL-TypeD; or if the QCL information is unknown to the UE. Exceptions may be specified additionally or alternatively if necessary. If no configured exceptions occur, the UE may be required or expected to be able to measure CSI-RS from neighboring cells for L1-SINR measurements without any restrictions, at least according to some implementation schemes.

[0176] In some cases, providing new Radio Resource Management (RRM) UE capabilities to support the use of gaps for monitoring multiple layers, including L1 measurements over neighboring cells, can be useful. For example, for standalone (SA) NR deployments, for RRM requirements, if the UE is configured to perform measurements on multiple frequency layers, parameter N... freq, SA It can be used to scale measurement latency. In cases where L1 measurements on neighboring cells are supported, it's possible that for N... freq, SASuch measurements should be considered. For example, as a possibility, 3GPP TS 38.133 for SA can be updated in section 9.1.3.1a as follows.

[0177] 9.1.3.1aSA: Using gaps to monitor multiple layers

[0178] The requirements in this clause apply to UEs configured with SA NR operating mode.

[0179] When the PCell is configured to use gaps (or not use gaps if the UE supports this capability) to monitor multiple inter-RAT E-UTRAN carriers, inter-frequency NR carriers (with or without CCA), and inter-RAT UTRA FDD carriers, the UE will be able to perform one of the configured measurement types (SS-RSRP, SS-RSRQ, SS-SINR, CSI-RSRP, CSI-RSRQ, CSI-SINR, E-UTRAN RSRP, E-UTRAN RSRQ, E-UTRAN RS-SINR measurement, UTRAN FDD CPICH measurement, L1-RSRP, L1-SINR, etc.) of the detected cells at all layers.

[0180] For a UE configured with NR SA operation, the total effective number of frequencies other than the frequencies being monitored (PCell, PSCell, and Scell) is N. freq, SA , is defined as:

[0181] N freq, SA = N freq, SA, NR + N freq, SA, E-UTRA + N freq, SA UTRA ,

[0182] in

[0183] N freq, SA, E-UTRA It is the number of monitored E-UTRA inter-RAT carriers (FDD and TDD) configured as by PCell or via LPP

[22] .

[0184] N freq, SA UTRA This refers to the number of UTRA FDD inter-RAT carriers being monitored, as configured by PCell.

[0185] N freq, SA, NR This refers to the number of NR frequency carriers being monitored, as configured by PCell.

[0186] It should be noted that similar updates (e.g., considering L1-RSRP, L1-SINR for multi-layer RRM monitoring) may also or alternatively apply to dual connectivity configurations (e.g., E-UTRAN-NR dual connectivity (EN-DC), NR-E-UTRAN dual connectivity (NE-DC), NR-NR dual connectivity (NR-DC)) and / or other configurations, such as in other parts of Section 9.1.3 of 3GPP TS 38.133.

[0187] In some implementations, for multiple monitoring operations including L1 measurements on neighboring cells, providing 3GPP specification guidance on the maximum permissible number of tiers may be useful. For example, as a possibility, Section 9.1.3.2a of 3GPP TS 38.133 could be updated as follows.

[0188] 9.1.3.2aSA: Maximum allowed number of layers for multiple monitoring

[0189] If the UE is configured with SA NR operating mode, the UE will be able to monitor at least:

[0190] -Depending on the UE's capabilities, the 7 NR SSB frequency carriers configured by the PCell, and

[0191] -Depending on the UE capabilities, the PCell configures a total of 8 NR inter-frequency carriers, including SSB and CSI-RS, and

[0192] - Depending on the UE capabilities, the PCell-configured X inter-frequency carriers for NR measurements, including L1-RSRP or L1-SINR, and

[0193] - Depending on the UE's capabilities, the PCell configures 7 E-UTRA TDD inter-RAT carriers, and

[0194] - Depending on the UE's capabilities, the PCell configures 7 E-UTRA FDD inter-RAT carriers, and

[0195] - Depending on the UE's capabilities, the PCell configures three UTRA FDD inter-RAT carriers, and

[0196] -Depending on the UE's capabilities, one E-UTRA FDD inter-RAT carrier configured via LBB

[22] for RSTD measurements, and

[0197] - Depending on the UE's capabilities, one E-UTRA TDD inter-RAT carrier configured via LBB

[22] for RSTD measurements.

[0198] In addition to the requirements defined above, the UE should also be able to monitor at least

[13] effective carrier frequency layers, including any combination of the above-defined layers of NR, E-UTRA FDD, E-UTRA TDD and UTRA FDD.

[0199] The number of SSB frequency layers is equal to the total number of MOs, where

[0200] -ssb-ConfigMobility is configured, or

[0201] -ssb-ConfigMobility is not configured, but csi-rs-ResourceConfigMobility is configured with associatedSSB, or

[0202] - L1-RSRP or L1-SINR on neighboring cells.

[0203] It should be noted that the value of X can be any of the various possible values, such as 7, 9, etc. It should also be noted that similar updates (e.g., considering the maximum allowed number of layers for multiple monitoring, L1-RSRP, L1-SINR) can also or alternatively apply to dual connectivity configurations and / or other configurations, as in other parts of Section 9.1.3 of 3GPP TS 38.133.

[0204] In some implementations, it may be useful to provide 3GPP specification guidance regarding the RRM UE's ability to consider the number of cells and SSBs for L1 measurements on neighboring cells. For example, for the inner frequency layer, as a possibility, Section 9.2.3 of 3GPP TS 38.133 may be updated as follows.

[0205] 9.2.3 Number of cells and number of SSBs

[0206] 9.2.3.1 Requirements for FR1

[0207] For each frequency inner layer, during each Layer 1 measurement cycle, the UE should be able to perform SS-RSRP, SS-RSRQ, L1-RSRP, L1-SINR, and SS-SINR measurements for at least the following:

[0208] -X1 identifies the cell, and

[0209] - X2 SSBs with different SSB indices and / or PCIs on the frequency inner layer, wherein the number of SSBs in the serving cell (other than SCell) is not less than the number of configured RLM-RS SSB resources.

[0210] 9.2.3.2 Requirements for FR2

[0211] For a single frequency inner layer within the frequency band, during each Layer 1 measurement cycle, the UE should be able to perform SS-RSRP, SS-RSRQ, L1-RSRP, L1-SINR, and SS-SINR measurements for at least the following:

[0212] -Y1 indicates the community, and

[0213] - Y2 SSB with different SSB indexes and / or PCI,

[0214] The inner layer of this single frequency should be:

[0215] -PCC, which is the PCC in the frequency band when the UE is configured with SA NR operating mode; or

[0216] -PSCC, which provides PSCC in the frequency band when the UE is configured with EN-DC; or

[0217] -PSCC, which provides PSCC in the frequency band when the UE is configured with NR-DC; or

[0218] When neither the PCC nor the PSCC is in the same frequency band, the UE is configured to report SSB-based measurements on one of the SCCs, such that the selected SCC should be the SCC on which the UE is configured to report SS-RSRP measurements (if such an SCC exists), otherwise the selected SCC is determined by the specific implementation of the UE.

[0219] The UE will also be able to perform SS-RSRP, SS-RSRQ and SS-SINR measurements for at least two SSBs on the serving cell to reach other frequency inner layers in the same frequency band.

[0220] It should be noted that the values ​​of X1, X2, Y1, and Y2 can be any of the various possible values. In some cases, it is possible that X1 is not less than 8, X2 is not less than 14, Y1 is not less than 6, and / or Y2 is not less than 24.

[0221] For example, regarding the inter-frequency layer, as a possibility, Section 9.3.3 of 3GPP TS 38.133 can be updated as follows.

[0222] 9.3.3 Number of cells and number of SSBs

[0223] 9.3.3.1 Requirements for FR1

[0224] For each inter-frequency layer, during each Layer 1 measurement cycle, the UE should be able to perform SS-RSRP, SS-RSRQ, L1-RSRP, L1-SINR, and SS-SINR measurements for at least the following:

[0225] -X1 identifies the cell, and

[0226] - X2 SSB with different SSB indices and / or PCI on the inter-frequency layer.

[0227] 9.3.3.2 Requirements for FR2

[0228] For each inter-frequency layer, during each Layer 1 measurement cycle, the UE should be able to perform SS-RSRP, SS-RSRQ, L1-RSRP, L1-SINR, and SS-SINR measurements for at least the following:
