Background Art

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

[0003] The introduction of an ever-increasing number of features and functions in wireless communication devices also requires continuous improvement in wireless communications and improvements in wireless communication devices. In order to increase coverage and better serve the increased demand and range of intended uses of wireless communications, in addition to the above-mentioned communication standards, there are wireless communication technologies being developed, including fifth generation (5G) new air interface (NR) communications. Therefore, there is a need for improvements in the field of supporting such development and design. Summary of the invention

[0004] Aspects disclosed herein relate to devices, circuits, and methods for configuring reference signal measurements for a wireless device, including: determining, by a user equipment (UE), that an aperiodic channel state information reference signal (AP-CSI-RS) measurement opportunity for layer 1 reference signal received power (L1-RSRP) overlaps with one or more layer 3 (L3) RS measurement opportunities; determining that the UE cannot measure both the AP-CSI-RS measurement opportunity for L1-RSRP and the one or more overlapping L3 RS measurement opportunities; and prioritizing, by the UE, measurements of the AP-CSI-RS measurement opportunity for L1-RSRP over measurements of the overlapping one or more L3 RS measurement opportunities.

[0005] According to other aspects, at least one of the one or more L3 RS measurement opportunities may include: one or more synchronization signal block (SSB) symbols or CSI-RS symbols for L3 RS measurement; one data symbol before the SSB or CSI-RS symbol and one data symbol after the SSB or CSI-RS symbol; or one or more received signal strength indication (RSSI) symbols and one data symbol before and after each of the one or more RSSI symbols.

[0006] According to yet other aspects, prioritizing, by the UE, measurements of an AP-CSI-RS measurement opportunity for L1-RSRP over measurements of one or more overlapping L3 RS measurement opportunities further includes prioritizing according to a scaling factor (e.g., a value representing a multiple of a period of the L1-RSRP or L3 RS measurement opportunity). According to other aspects, prioritizing measurements of an AP-CSI-RS measurement opportunity for L1-RSRP over measurements of one or more overlapping L3 RS measurement opportunities further includes silencing at least one L3 RS measurement opportunity (e.g., to ensure that AP-CSI-RS for L1-RSRP is received in at least the first overlapping measurement opportunity).

[0007] In other aspects, if AP-CSI-RS for L1-RSRP overlaps with one or more measurement gap (MG) opportunities, the overlapping MGs may take precedence over receiving AP-CSI-RS measurements for L1-RSRP (e.g., by silencing AP-CSI-RS measurements for L1-RSRP).

[0008] Additional aspects disclosed herein relate to devices, circuits, and methods for configuring reference signal transmission by a wireless network, including: determining, by a wireless network (NW), that a user equipment (UE) cannot provide both aperiodic channel state information reference signal (AP-CSI-RS) measurement and layer 3 (L3) RS measurement for layer 1 reference signal received power (L1-RSRP) in overlapping measurement opportunities; and configuring, by the NW, AP-CSI-RS measurement or L3 RS measurement for L1-RSRP to avoid overlapping measurement opportunities.

[0009] According to some such aspects, configuring AP-CSI-RS measurement or L3 RS measurement for L1-RSRP to avoid overlapping measurement opportunities further comprises one or more of the following: configuring AP-CSI-RS or L3 RS for L1-RSRP so that the AP-CSI-RS for L1-RSRP avoids overlapping with a synchronization signal block (SSB) symbol or CSI-RS symbol for L3 RS measurement; configuring AP-CSI-RS or L3 RS for L1-RSRP so that the AP-CSI-RS for L1-RSRP avoids overlapping with a data symbol before the SSB or CSI-RS symbol for L3 RS measurement and a data symbol after the SSB or CSI-RS symbol for L3 RS measurement; configuring AP-CSI-RS or L3 RS for L1-RSRP so that the AP-CSI-RS for L1-RSRP avoids overlapping with a data symbol before the SSB or CSI-RS symbol for L3 RS measurement and a data symbol after the SSB or CSI-RS symbol for L3 RS measurement. RS, so that the AP-CSI-RS for L1-RSRP avoids overlapping with one or more received signal strength indication (RSSI) symbols and one data symbol before and after each of the one or more RSSI symbols; or configure the AP-CSI-RS or L3 RS for L1-RSRP to avoid a configuration in which multiple AP-CSI-RS measurement opportunities for L1-RSRP overlap with all L3 RS measurement opportunities in the first time interval.

[0010] According to other aspects, a method for configuring reference signal (RS) transmission by a wireless network is disclosed, including: determining, by a wireless network (NW), that a user equipment (UE) cannot provide both aperiodic channel state information reference signal (AP-CSI-RS) measurement for layer 1 reference signal received power (L1-RSRP) and layer 3 (L3) RS measurement in overlapping measurement opportunities; and configuring, by the NW, AP-CSI-RS measurement or L3 RS measurement for L1-RSRP to avoid a configuration in which multiple AP-CSI-RS measurement opportunities for L1-RSRP overlap with all L3 RS measurement opportunities in a first time interval. In some such aspects, configuring AP-CSI-RS measurement or L3 RS measurement for L1-RSRP also includes: changing the timing of at least one of the L3 RS measurement opportunities (e.g., changing at least one of the following: a period, an offset, or a starting point of the L3 measurement RS opportunity, or a bitmap associated with a synchronization signal block (SSB) in the time domain).

[0011] In some other aspects, configuring AP-CSI-RS or L3 RS measurement for L1-RSRP also includes: for each AP-CSI-RS measurement opportunity for L1-RSRP: determining by the NW whether the AP-CSI-RS measurement opportunity for L1-RSRP will overlap with the L3 RS measurement opportunity; and when it is determined that the AP-CSI-RS measurement opportunity for L1-RSRP will overlap with the L3 RS measurement opportunity, changing the timing of the AP-CSI-RS measurement opportunity for L1-RSRP.

[0012] The techniques described herein may be implemented in and / or used with a number of different types of devices, including, but not limited to, any of cellular telephones, wireless devices, wireless base stations, tablet computers, wearable computing devices, portable media players, and a variety of other computing devices.

[0027] Although the features described herein are susceptible to various modifications and alternative forms, specific aspects thereof are shown by way of example in the drawings and described in detail herein.

DETAILED DESCRIPTION

[0028] In 5G / NR, conflicts between measurements of different reference signals (RS) (e.g., conflicts caused by using overlapping measurement opportunities in the time domain) are an issue that must be addressed in an appropriate and reasonable manner. In 3GPP TS38.133, measurement conflicts between various RSs have been considered, and these considerations can be summarized as shown in Table 1 below (see also, for example, ETSI TS 138133 V15.8.0 (2020-02), Sections 8.5.2–8.5.3).

[0029] Measurement restriction and sharing scheme for conflicting RSs (Rel-16)

[0030]

[0031] Table 1

[0032] In the cells of Table 1 marked with an asterisk above, the CSI-RS used for L1-RSRP measurement can have three possible types: periodic CSI-RS (P-CSI-RS), semi-persistent CSI-RS (SP-CSI-RS), or aperiodic CSI-RS (AP-CSI-RS). In this context, semi-persistent CSI-RS is similar to periodic CSI-RS, however, SP-CSI-RS is only sent after the network has specifically configured and activated the UE for SP-CSI-RS.

[0033] There may be some potential problems when, for example, AP-CSI-RS is configured for L1-RSRP and the AP-CSI-RS collides with one or more other RSs used for L3RRM measurement (e.g., synchronization signal blocks (SSBs) or CSI-RS for L3 measurement). Potential problems can be observed in the case when the UE cannot simultaneously receive or measure the AP-CSI-RS for L1-RSRP and the RS for L3 measurement due to, for example, mixed parameter sets and / or Rx beam scanning.

[0034] Therefore, in certain wireless communication systems, it may be desirable to explicitly define preferred user equipment (e.g., UE) behavior for measuring multiple different types of reference signals (RS) with conflicting measurement window opportunities, so that the UE (with or without assistance from the network) can perform reasonable measurement activities on the available RSs.

[0035] The following is a glossary of terms that may be used in this disclosure:

[0036] Memory medium - any of various types of non-transitory memory devices or storage devices. The term "memory medium" is intended to include installation media, such as CD-ROM, floppy disk or 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, for example, hard disk drive or optical storage device; registers or other similar types of memory elements, etc. The memory medium may also include other types of non-transitory memory or a combination thereof. In addition, the memory medium may be located in the first computer system executing the program, or may be located in a different second computer system connected to the first computer system via a network such as the Internet. In the latter case, the second computer system may provide program instructions to the first computer for execution. The term "memory medium" may include two or more memory media that may reside in different locations in different computer systems connected, for example, via a network. The memory medium may store program instructions (e.g., in the form of a computer program) that may be executed by one or more processors.

[0037] Carrier Medium—storage media as described above and physical transmission media such as a bus, network, and / or other physical transmission media that convey signals such as electrical, electromagnetic, or digital signals.

[0038] Programmable hardware element - includes various hardware devices that include multiple programmable function blocks connected via programmable interconnects. Examples include FPGA (field programmable gate array), PLD (programmable logic device), FPOA (field programmable object array), and CPLD (complex PLD). Programmable function blocks can vary from fine-grained (combinational logic unit or lookup table) to coarse-grained (arithmetic logic unit or processor core). Programmable hardware elements may also be referred to as "configurable logic units".

[0039] Computer System—Any of various types of computing or processing systems, including a personal computer system (PC), a mainframe computer system, a workstation, a network appliance, an Internet appliance, a personal digital assistant (PDA), a television system, a grid computing system, or other devices or combinations of devices.

Examples of UE devices include mobile phones or smartphones (e.g., iPhone-based TM 、AndroidTM phones), portable gaming devices (e.g., Nintendo DS TM , PlayStation Portable TM 、Gameboy Advance TM , iPhone TM ), laptops, wearable devices (e.g., smart watches, smart glasses), PDAs, portable internet devices, music players, data storage devices, other handheld devices, in-vehicle infotainment (IVI), in-car entertainment (ICE) devices, instrument clusters, heads-up display (HUD) devices, on-board diagnostic (OBD) devices, dashboard mobile equipment (DME), mobile data terminals (MDT), electronic engine management systems (EEMS), electronic / engine control units (ECU), electronic / engine control modules (ECM), embedded systems, microcontrollers, control modules, engine management systems (EMS), networked or "smart" appliances, machine type communication (MTC) devices, machine to machine (M2M), Internet of Things (IoT) devices, etc. In general, the term "UE" or "UE device" or "user equipment" can be broadly defined to cover any electronic, computing and / or telecommunication device (or combination of devices) that is easily transportable by a user (or vehicle) and is capable of wireless communication.

[0041] Wireless Device—Any of various types of computer systems or devices that perform wireless communications. A wireless device may be portable (or mobile), or may be stationary or fixed at a certain location. A UE is an example of a wireless device.

[0042] Communication device - any of various types of computer systems or devices that perform communication, where the communication may be wired or wireless. A communication device may be portable (or mobile), or may be stationary or fixed at a location. A wireless device is an example of a communication device. A UE is another example of a communication device.

[0043] Base Station—The term “base station,” “wireless base station,” or “wireless station” has the full scope of its ordinary meaning and includes at least a wireless communication station that is installed at a fixed location and used to communicate as part of a wireless telephone system or radio system. For example, if a base station is implemented in the context of LTE, it may alternatively be referred to as an “eNodeB” or “eNB.” If a base station is implemented in the context of 5GNR, it may alternatively be referred to as a “gNodeB” or “gNB.” Although certain aspects are described in the context of LTE or 5G NR, references to “eNB,” “gNB,” “nodeB,” “base station,” “NB,” etc. may also refer to one or more wireless nodes that serve a cell to provide wireless connectivity between a user device and a generally wider network, and the concepts discussed are not limited to any particular wireless technology. Although certain aspects are described in the context of LTE or 5G NR, references to “eNB,” “gNB,” “nodeB,” “base station,” “NB,” etc. are not intended to limit the concepts discussed herein to any particular wireless technology, and the concepts discussed may be applied to any wireless system.

[0044] Node—As used herein, the term “node” or “wireless node” may refer to one or more devices associated with a cell that provides wireless connectivity between user equipment and a typically wired network.

[0045] Processing element (or processor) - refers to various elements or combinations of elements that are capable of performing functions in a device such as user equipment or cellular network equipment. Processing elements may include, for example, processors and associated memory, portions or circuits of individual processor cores, entire processor cores, separate processors, processor arrays, circuits such as ASICs (application specific integrated circuits), programmable hardware elements such as field programmable gate arrays (FPGAs), and any of the above combinations.

[0046] Channel - a medium used to transmit information from a sender (transmitter) to a receiver. It should be noted that since the characteristics of the term "channel" may vary according to different wireless protocols, the term "channel" used in the present invention may be considered to be used in a manner that conforms to the standards of the type of device to which the term is used. In some standards, the channel width may be variable (e.g., depending on device capabilities, frequency band conditions, etc.). For example, LTE may support scalable channel bandwidths of 1.4MHz to 20MHz. In contrast, a WLAN channel may be 22MHz wide, while a Bluetooth channel may be 1Mhz wide. Other protocols and standards may include different definitions of channels. In addition, some standards may define and use multiple types of channels, such as different channels for uplink or downlink and / or different channels for different purposes such as data, control information, etc.

[0047] Frequency band—The term “frequency band” has the full breadth of its ordinary meaning and includes at least a segment of the spectrum (eg, radio frequency spectrum) in which channels are used or set aside for the same purpose.

[0048] Automatic—refers to an action or operation being performed by a computer system (e.g., software executed by a computer system) or a device (e.g., a circuit, a programmable hardware element, an ASIC, etc.) without the need for the action or operation to be directly specified or performed by a user input. Thus, the term "automatic" is in contrast to a user manually performing or specifying an action (where the user provides input to directly perform the action). An automatic process may be initiated by input provided by a user, but subsequent actions performed "automatically" are not specified by the user, i.e., are not performed "manually," where the user specifies each action to be performed. For example, a user filling out an electronic form by selecting each field and providing input specifying information (e.g., by typing in information, selecting checkboxes, radio selections, etc.) is manually filling out the form, even though the computer system must update the form in response to the user action. The form may be automatically filled out by a computer system, where the computer system (e.g., software executed on the computer system) analyzes the fields of the form and fills out the form without any user input specifying the answers to the fields. As indicated above, a user may invoke automatic filling out of a form, but not participate in the actual filling out of the form (e.g., the user does not manually specify the answers to the fields but rather they are automatically completed). This specification provides various examples of operations that are automatically performed in response to actions taken by a user.

[0049] About - refers to a value that is close to a correct or exact value. For example, about can refer to a value that is within 1% to 10% of an exact (or desired) value. However, it should be noted that the actual threshold (or tolerance) may depend on the application. For example, in some aspects, "about" may mean within 0.1% of some specified or desired value, while in various other aspects, the threshold may be, for example, 2%, 3%, 5%, etc., depending on the desires or requirements of a particular application.

[0050] Concurrency - refers to parallel execution or implementation, where tasks, processes, or programs are executed in an at least partially overlapping manner. For example, concurrency can be achieved using "strong" or strict parallelism, where tasks are executed (at least partially) in parallel on respective computing elements, or using "weak parallelism," where tasks are executed in an interleaved manner (e.g., by time multiplexing of execution threads).

[0051] Configured to - Various components may be described as being "configured to" perform one or more tasks. In such environments, "configured to" is a broad statement that generally means "having a structure" that performs one or more tasks during operation. Thus, a component can be configured to perform a task even when the component is not currently performing the task (e.g., a set of electrical conductors can be configured to electrically connect a module to another module even when the two modules are not connected). In some contexts, "configured to" can be a broad statement that generally means "having a structure" that performs one or more tasks during operation. Thus, the component can be configured to perform a task even when the component is not currently turned on. Typically, the circuitry that forms the structure corresponding to "configured to" may include hardware circuitry.

[0052] For ease of description, various components may be described as performing one or more tasks. Such descriptions should be interpreted as including the phrase "configured to". The description of a component being configured to perform one or more tasks is expressly intended not to invoke 35 U.S.C. §112(f) interpretation of that component.

[0053] Exemplary Wireless Communication System

[0054] Now go to Figure 1 , shows a simplified example of a wireless communication system according to some aspects. Note that Figure 1 The system is only one example of possible systems, and features of the present disclosure may be implemented in any of a variety of systems as desired.

[0055] As shown, the exemplary wireless communication system includes a base station 102A, which communicates with one or more user equipment 106A, user equipment 106B to user equipment 106N, etc. through a transmission medium. Each user equipment may be referred to as a "user equipment" (UE) in this article. Therefore, user equipment 106 is referred to as UE or UE device.

[0056] The base station (BS) 102A may be a base transceiver station (BTS) or a cell site ("cellular base station") and may include hardware that enables wireless communications with the UEs 106A through 106N.

[0057] The communication area (or coverage area) of a base station may be referred to as a "cell". The base station 102A and the UE 106 may be configured to communicate over a transmission medium using any of a variety of radio access technologies (RATs), which are also referred to as wireless communication technologies or telecommunication standards, such as GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces), LTE, Advanced LTE (LTE-A), 5G New Radio (5G-NR), HSPA, 3GPP2CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), and the like. Note that if the base station 102A is implemented in the context of LTE, it may alternatively be referred to as an "eNodeB" or "eNB". Note that if the base station 102A is implemented in the context of 5G NR, it may alternatively be referred to as a "gNodeB" or "gNB".

[0058] In some aspects, UE 106 may be an IoT UE that may include a network access layer designed for low-power IoT applications that utilize short-term UE connections. The IoT UE may utilize technologies such as M2M or MTC to exchange data with an MTC server or device via a public land mobile network (PLMN), a short-range service (ProSe), or a device-to-device (D2D) communication, a sensor network, or an IoT network. M2M or MTC data exchange may be a machine-initiated data exchange. The IoT network describes interconnected IoT UEs that may include uniquely identifiable embedded computing devices (within the Internet infrastructure) with short-lived connections. As an example, vehicle-to-everything (V2X) may utilize ProSe features using a PC5 interface to communicate directly between devices. The IoT UE may also execute background applications (e.g., keep-alive messages, status updates, etc.) to facilitate connectivity to the IoT network.

[0059] As shown, UE 106 (such as UE 106A and UE 106B) can directly exchange communication data via PC5 interface 108. For example, PC5 interface 105 may include one or more logical channels, including but not limited to a physical sidelink shared channel (PSSCH), a physical sidelink control channel (PSCCH), a physical sidelink broadcast channel (PSBCH), and a physical sidelink feedback channel (PSFCH).

[0060] In a V2X scenario, one or more of the base stations 102 may be a roadside unit (RSU) or act as an RSU. The term RSU may refer to any transportation infrastructure entity used for V2X communication. The RSU may be implemented in or by a suitable wireless node or a stationary (or relatively stationary) UE, wherein an RSU implemented in or by a UE may be referred to as a "UE-type RSU", an RSU implemented in or by an eNB may be referred to as an "eNB-type RSU", an RSU implemented in or by a gNB may be referred to as a "gNB-type RSU", and so on. In one example, the RSU is a computing device coupled to a radio frequency circuit located on the road side that provides connectivity support to a passing vehicle UE (vUE). The RSU may also include internal data storage circuitry for storing intersection map geometry, traffic statistics, media, and applications / software for sensing and controlling ongoing vehicle and pedestrian traffic. The RSU may operate on the 5.9 GHz Intelligent Transportation System (ITS) band to provide extremely low latency communications required for high-speed events, such as collision avoidance, traffic warnings, etc. In addition or alternatively, the RSU may operate on the cellular V2X band to provide the aforementioned low latency communications as well as other cellular communication services. In addition or alternatively, the RSU may operate as a Wi-Fi hotspot (2.4 GHz band) and / or provide connectivity to one or more cellular networks to provide uplink and downlink communications. Some or all of the computing device and the RSU's RF circuitry may be packaged in a weather-resistant enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller and / or backhaul network.

[0061] As shown, base station 102A may also be configured to communicate with network 100 (e.g., a core network of a cellular service provider, a telecommunications network such as a public switched telephone network (PSTN), and / or the Internet, among other possibilities). Thus, base station 102A may facilitate communications between user devices and / or between user devices and network 100. In particular, cellular base station 102A may provide UE 106 with various communication capabilities, such as voice, SMS, and / or data services.

[0062] Base station 102A and other similar base stations (such as base stations 102B...102N) operating according to the same or different cellular communication standards can therefore be provided as a network of cells that can provide continuous or nearly continuous overlapping service to UE 106A-N and similar devices over a geographic area via one or more cellular communication standards.

[0063] Thus, although base station 102A may function as Figure 1106A-N, but each UE 106 may also be able to receive signals from (and possibly be within communication range of) one or more other cells (which may be provided by base stations 102B-N and / or any other base stations), which may be referred to as "neighboring cells." Such cells may also be able to facilitate communications between user devices and / or between user devices and network 100. Such cells may include "macro" cells, "micro" cells, "pico" cells, and / or cells of any various other granularity of service area size. For example, in Figure 1 The base stations 102A-102B shown in FIG. 1 may be macro cells, while the base station 102N may be a micro cell. Other configurations are also possible.

[0064] In some aspects, base station 102A may be a next generation base station, such as a 5G New Radio (5GNR) base station or "gNB". In some aspects, the gNB may be connected to a legacy evolved packet core (EPC) network and / or to an NR core (NRC) / 5G core (5GC) network. In addition, a gNB cell may include one or more transition and reception points (TRPs). In addition, a UE capable of operating in accordance with 5G NR may be connected to one or more TRPs within one or more gNBs. For example, base station 102A and one or more other base stations 102 may support joint transmissions such that UE 106 may be able to receive transmissions from multiple base stations (and / or multiple TRPs provided by the same base station). For example, as Figure 1 As shown, base station 102A and base station 102C are both shown serving UE 106A.

[0065] It should be noted that the UE 106 is capable of communicating using multiple wireless communication standards. For example, in addition to at least one cellular communication protocol (e.g., GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interface), LTE, LTE-A, 5G NR, HSPA, 3GPP2CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc.), the UE 106 can be configured to communicate using wireless networking (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer, etc.). If desired, the UE 106 can also or alternatively be configured to communicate using one or more global navigation satellite systems (GNSS, such as GPS or GLONASS), one or more mobile television broadcast standards (e.g., Advanced Television Systems Committee—Mobile / Handheld (ATSC-M / H)), and / or any other wireless communication protocol. Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.

[0067] Figure 2 A user equipment 106 (e.g., one of devices 106A-106N) is shown in accordance with some aspects in communication with base station 102. UE 106 may be a device with cellular communication capabilities, such as a mobile phone, handheld device, computer, laptop, tablet, smart watch or other wearable device, or indeed any type of wireless device.

[0068] UE 106 may include a processor (processing element) configured to execute program instructions stored in a memory. UE 106 may perform any of the method aspects described herein by executing such stored instructions. Alternatively or in addition, UE 106 may include a programmable hardware element, such as an FPGA (field programmable gate array), an integrated circuit, and / or any of a variety of other possible hardware components configured to perform (e.g., individually or in combination) any of the method aspects described herein or any portion of any of the method aspects described herein.

[0069] UE 106 may include one or more antennas for communicating using one or more wireless communication protocols or technologies. In some aspects, UE 106 may be configured to communicate using, for example, NR or LTE using at least some shared radio components. As an additional possibility, the UE 106 may be configured to communicate using CDMA2000 (1xRTT / 1xEV-DO / HRPD / eHRPD) or LTE using a single shared radio component and / or GSM or LTE using a single shared radio component. The shared radio may be coupled to a single antenna, or may be coupled to multiple antennas (e.g., for MIMO) for performing wireless communications. Typically, the radio component may include any combination of a baseband processor, an analog radio frequency (RF) signal processing circuit (e.g., including filters, mixers, oscillators, amplifiers, etc.), or a digital processing circuit (e.g., for digital modulation and other digital processing). Similarly, the radio component may use the aforementioned hardware to implement one or more receive chains and transmit chains. For example, UE 106 may share one or more portions of a receive chain and / or transmit chain between multiple wireless communication technologies such as those discussed above.

[0070] In some aspects, the UE 106 may include a separate transmit chain and / or receive chain (e.g., including separate antennas and other radio components) for each wireless communication protocol with which it is configured to communicate. As another possibility, the UE 106 may include one or more radio components shared between multiple wireless communication protocols, and one or more radio components used uniquely by a single wireless communication protocol. For example, the UE 106 may include a shared radio component for communicating using either LTE or 5G NR (or, in various possibilities, either LTE or 1xRTT, or either LTE or GSM), and an independent radio component for communicating using each of Wi-Fi and Bluetooth. Other configurations are also possible.

[0071] In some aspects, a downlink resource grid may be used for downlink transmissions from any of the base stations 102 to the UE 106, while uplink transmissions may utilize similar techniques. The grid may be a time-frequency grid, referred to as a resource grid or a time-frequency resource grid, which is a physical resource in the downlink in each time slot. For OFDM systems, such a time-frequency plane representation is a common practice, which makes radio resource allocation intuitive. Each column and each row of the resource grid corresponds to an OFDM symbol and an OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to a time slot in a radio frame. The smallest time-frequency unit in the resource grid is represented as a resource element. Each resource grid may include multiple resource blocks, which describe the mapping of specific physical channels to resource elements. Each resource block includes a collection of resource elements. Such resource blocks are used to transmit several different physical downlink channels.

[0072] The physical downlink shared channel (PDSCH) may carry user data and higher layer signaling to the UE 106. The physical downlink control channel (PDCCH) may carry information about, among other things, the transport format and resource allocation associated with the PDSCH channel. It may also inform the UE 106 of the transport format, resource allocation, and H-ARQ (Hybrid Automatic Repeat Request) information associated with the uplink shared channel. Typically, downlink scheduling (allocation of control and shared channel resource blocks to the UE 102 within the cell) may be performed at any of the base stations 102 based on channel quality information fed back from any of the UEs 106. Downlink resource allocation information may be sent on the PDCCH for (e.g., allocated to) each of the UEs.

[0073] PDCCH can use control channel elements (CCE) to transmit control information. Before being mapped to resource elements, the PDCCH complex-valued symbols can first be organized into quadruplets, which can then be arranged using a sub-block interleaver for rate matching. One or more of these CCEs can be used to transmit each PDCCH, where each CCE can correspond to four sets of nine physical resource elements, called resource element groups (REGs). Four quadrature phase shift keying (QPSK) symbols can be mapped to each REG. Depending on the size of the downlink control information (DCI) and channel conditions, one or more CCEs can be used to transmit the PDCCH. There may be four or more different PDCCH formats defined in LTE with different numbers of CCEs (e.g., aggregation levels, L=1, 2, 4, or 8).

[0074] Exemplary Communication Devices

[0075] Figure 3 1 shows an exemplary simplified block diagram of a communication device 106 according to some aspects. Note that Figure 3 The block diagram of the communication device is only an example of a possible communication device. According to various aspects, the communication device 106 can be a user equipment (UE) device, a mobile device or mobile station, a wireless device or wireless station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, a notebook or a portable computing device), a tablet computer and / or a combination of devices, in addition to other devices. As shown, the communication device 106 may include a group of components 300 configured to perform core functions. For example, the group of components may be implemented as a system on a chip (SOC), which may include parts for various purposes. Alternatively, the group of components 300 may be implemented as a separate component or group of components for various purposes. This group of components 300 may be coupled to various other circuits of the communication device 106 (e.g., communicatively; directly or indirectly).

[0076] For example, the communication device 106 may include various types of memory (e.g., including NAND flash memory 310), input / output interfaces such as connector I / F 320 (e.g., for connecting to a computer system; a docking station; a charging station; input devices such as a microphone, camera, keyboard; output devices such as speakers; etc.), a display 360 that may be integrated with the communication device 106 or external to it, and wireless communication circuitry 330 (e.g., for LTE, LTE-A, NR, UMTS, GSM, CDMA2000, Bluetooth, Wi-Fi, NFC, GPS, etc.). In some aspects, the communication device 106 may include wired communication circuitry (not shown), such as, for example, a network interface card for Ethernet.

[0077] Wireless communication circuitry 330 may be (e.g., communicatively; directly or indirectly) coupled to one or more antennas, such as one or more antennas 335 as shown. Wireless communication circuitry 330 may include cellular communication circuitry and / or short- to medium-range wireless communication circuitry, and may include multiple receive chains and / or multiple transmit chains for receiving and / or transmitting multiple spatial streams, such as in a multiple-input multiple-output (MIMO) configuration.

[0078] In some aspects, as further described below, the cellular communication circuitry 330 can include one or more receive chains for multiple RATs (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components (e.g., a first receive chain for LTE and a second receive chain for 5G NR). Further, in some aspects, the cellular communication circuitry 330 can include a single transmit chain that can switch between radio components dedicated to specific RATs. For example, a first radio component can be dedicated to a first RAT (e.g., LTE) and can communicate with a dedicated receive chain and a transmit chain shared with a second radio component. The second radio component can be dedicated to a second RAT (e.g., 5G NR). NR), and can communicate with a dedicated receive chain and a shared transmit chain. In some aspects, the second RAT can operate at millimeter wave frequencies. Since the operating frequency of the millimeter wave system is higher than the typical frequency in the LTE system, the signals in the millimeter wave frequency range are severely attenuated due to environmental factors. To help solve this attenuation problem, millimeter wave systems typically utilize beamforming and include more antennas than LTE systems. These antennas can be organized into antenna arrays or panels composed of individual antenna elements. These antenna arrays can be coupled to the radio link.

[0079] The communication device 106 may also include and / or be configured for use with one or more user interface elements. The user interface elements may include various elements such as a display 360 (which may be a touch screen display), a keyboard (which may be a separate keyboard or may be implemented as part of a touch screen display), a mouse, a microphone and / or speakers, one or more cameras, one or more buttons, and / or any of a variety of other elements capable of providing information to a user and / or receiving or interpreting user input.

[0080] The communication device 106 may also include one or more smart cards 345 having SIM (Subscriber Identity Module) functionality, such as one or more UICC cards (one or more Universal Integrated Circuit Cards) 345 .

[0081] As shown, the SOC 300 may include a processor 302 that may execute program instructions for the communication device 106 and a display circuit 304 that may perform graphics processing and provide display signals to a display 360. The one or more processors 302 may also be coupled to a memory management unit (MMU) 340 (which may be configured to receive addresses from the one or more processors 302 and convert those addresses to locations in a memory (e.g., a memory 306, a read-only memory (ROM) 350, a NAND flash memory 310)), and / or to other circuits or devices (such as the display circuit 304, the wireless communication circuit 330, the connector I / F 320, and / or the display 360). The MMU 340 may be configured to perform memory protection and page table translation or setup. In some aspects, the MMU 340 may be included as part of the processor 302.

[0082] As described above, the communication device 106 may be configured to communicate using wireless and / or wired communication circuits. As described herein, the communication device 106 may include hardware and software components for implementing any of the various features and techniques described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transient computer-readable memory medium), the processor 302 of the communication device 106 may be configured to implement part or all of the features described in the present invention. Alternatively (or in addition thereto), the processor 302 may be configured as a programmable hardware element, such as an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit). Alternatively (or in addition thereto), in combination with one or more components in other components 300, 304, 306, 310, 320, 330, 340, 345, 350, 360, the processor 302 of the communication device 106 may be configured to implement part or all of the features described herein.

[0083] In addition, as described in the present invention, processor 302 may include one or more processing elements. Therefore, processor 302 may include one or more integrated circuits (ICs) configured to perform the functions of processor 302. In addition, each integrated circuit may include circuits (e.g., first circuits, second circuits, etc.) configured to perform the functions of one or more processors 302.

[0084] In addition, as described herein, wireless communication circuit 330 may include one or more processing elements. In other words, one or more processing elements may be included in wireless communication circuit 330. Therefore, wireless communication circuit 330 may include one or more integrated circuits (ICs) configured to perform the functions of wireless communication circuit 330. In addition, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of wireless communication circuit 330.

[0085] Exemplary Base Station

[0086] Figure 4 1 shows an exemplary block diagram of a base station 102 according to some aspects. Note that Figure 4 The base station of is only one example of a possible base station. As shown, the base station 102 may include a processor 404 that may execute program instructions for the base station 102. The processor 404 may also be coupled to a memory management unit (MMU) 440 or other circuit or device, which may be configured to receive addresses from the processor 404 and convert these addresses to locations in memory (e.g., memory 460 and read-only memory (ROM) 450).

[0087] Base station 102 may include at least one network port 470. Network port 470 may be configured to couple to a telephone network and provide access to the telephone network described above. Figure 1 and Figure 2 Multiple devices of the telephone network described in, such as UE device 106.

[0088] The network port 470 (or an additional network port) may also or alternatively be configured to couple to a cellular network, such as a core network of a cellular service provider. The core network may provide mobility-related services and / or other services to multiple devices, such as the UE device 106. In some cases, the network port 470 may be coupled to a telephone network via the core network, and / or the core network may provide a telephone network (e.g., in other UE devices served by the cellular service provider).

[0089] In some aspects, base station 102 may be a next generation base station, e.g., a 5G New Radio (5GNR) base station or "gNB". In such aspects, base station 102 may be connected to a legacy evolved packet core (EPC) network and / or to an NR core (NRC) / 5G core (5GC) network. Furthermore, base station 102 may be considered a 5G NR cell and may include one or more transition and reception points (TRPs). Furthermore, a UE capable of operating in accordance with 5G NR may be connected to one or more TRPs within one or more gNBs.

[0090] The base station 102 may include at least one antenna 434 and possibly multiple antennas. The at least one antenna 434 may be configured to function as a wireless transceiver and may be further configured to communicate with the UE device 106 via the radio component 430. The antenna 434 communicates with the radio component 430 via a communication chain 432. The communication chain 432 may be a receive chain, a transmit chain, or both. The radio component 430 may be configured to communicate via various wireless communication standards, including but not limited to 5G NR, LTE, LTE-A, GSM, UMTS, CDMA2000, Wi-Fi, etc.

[0091] The base station 102 may be configured to perform wireless communications using multiple wireless communication standards. In some cases, the base station 102 may include multiple radios that enable the base station 102 to communicate according to multiple wireless communication technologies. For example, as one possibility, the base station 102 may include an LTE radio component for performing communications according to LTE and a 5GNR radio component for performing communications according to 5GNR. In this case, the base station 102 may be able to operate as both an LTE base station and a 5G NR base station. When the base station 102 supports millimeter waves, the 5G NR radio component may be coupled to one or more millimeter wave antenna arrays or panels. As another possibility, the base station 102 may include a multimode radio component that can perform communications according to any one of a plurality of wireless communication technologies (e.g., 5G NR and LTE, 5G NR and Wi-Fi, LTE and Wi-Fi, LTE and UMTS, LTE and CDMA2000, UMTS and GSM, etc.).

[0092] As further described later herein, BS 102 may include hardware and software components for implementing or supporting specific implementations of the features described herein. The processor 404 of base station 102 may be configured to implement or support some or all of the embodiments 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 an FPGA (field programmable gate array), or as an ASIC (application-specific integrated circuit) or a combination thereof. Alternatively (or in addition thereto), in combination with one or more of other components 430, 432, 434, 440, 450, 460, 470, the processor 404 of base station 102 may be configured to implement or support some or all of the embodiments of the features described herein.

[0093] In addition, as described herein, the one or more processors 404 may include one or more processing elements. Thus, the processor 404 may include one or more integrated circuits (ICs) configured to perform the functions of the processor 404. In addition, each integrated circuit may include circuits (e.g., first circuits, second circuits, etc.) configured to perform the functions of the one or more processors 404.

[0094] In addition, as described herein, radio 430 may include one or more processing elements. Thus, radio 430 may include one or more integrated circuits (ICs) configured to perform the functions of radio 430. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of radio 430.

[0095] Exemplary Cellular Communications Circuitry

[0096] Figure 5 An exemplary simplified block diagram of a cellular communication circuit according to some aspects is shown. Note that Figure 5 The block diagram of the cellular communication circuitry of is only one example of possible cellular communication circuitry; other circuitry, such as circuitry that includes or is coupled to sufficient antennas for different RATs to perform uplink activities using separate antennas, or circuitry that includes or is coupled to fewer antennas, such as circuitry that can be shared between multiple RATs, is also possible. According to some aspects, the cellular communication circuitry 330 may be included in a communication device such as the communication device 106 described above. As described above, the communication device 106 may be a user equipment (UE) device, a mobile device or mobile station, a wireless device or wireless station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, notebook, or portable computing device), a tablet computer, and / or a combination of devices, among other devices.

[0097] The cellular communication circuitry 330 may be (e.g., communicatively; directly or indirectly) coupled to one or more antennas, such as antennas 335a-b and 336 as shown. In some aspects, the cellular communication circuitry 330 may include dedicated receive chains for multiple RATs (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components (e.g., a first receive chain for LTE and a second receive chain for 5G NR). For example, Figure 5 As shown, the cellular communication circuit 330 may include a first modem 510 and a second modem 520. The first modem 510 may be configured for communication according to a first RAT (e.g., such as LTE or LTE-A), and the second modem 520 may be configured for communication according to a second RAT (e.g., such as 5G NR).

[0098] As shown, the first modem 510 may include one or more processors 512 and a memory 516 in communication with the processor 512. The modem 510 may communicate with a radio frequency (RF) front end 530. The RF front end 530 may include circuits for transmitting and receiving radio signals. For example, the RF front end 530 may include a receiving circuit (RX) 532 and a transmitting circuit (TX) 534. In some aspects, the receiving circuit 532 may communicate with a downlink (DL) front end 550, which may include circuits for receiving radio signals via an antenna 335a.

[0099] Similarly, the second modem 520 may include one or more processors 522 and a memory 526 in communication with the processor 522. The modem 520 may communicate with the RF front end 540. The RF front end 540 may include circuits for transmitting and receiving radio signals. For example, the RF front end 540 may include a receiving circuit 542 and a transmitting circuit 544. In some aspects, the receiving circuit 542 may communicate with the DL front end 560, which may include circuits for receiving radio signals via the antenna 335b.

[0100] In some aspects, the switch 570 may couple the transmit circuit 534 to an uplink (UL) front end 572. In addition, the switch 570 may couple the transmit circuit 544 to the UL front end 572. The UL front end 572 may include circuitry for transmitting radio signals via the antenna 336. Thus, when the cellular communication circuit 330 receives an instruction to transmit according to a first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572) supported by the first modem 510, the switch 570 may be switched to a first state that allows the first modem 510 to transmit signals according to the first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572). Similarly, when the cellular communication circuit 330 receives an instruction to transmit according to a second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572) supported by the second modem 520, the switch 570 may be switched to a second state that allows the second modem 520 to transmit signals according to the second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572).

[0101] As described herein, the first modem 510 and / or the second modem 520 may include hardware and software components for implementing any of the various features and techniques described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processors 512, 522 may be configured to implement part or all of the features described herein. Alternatively (or in addition), the processors 512, 522 may be configured as programmable hardware elements, such as an FPGA (field programmable gate array) or as an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more of the other components 530, 532, 534, 540, 542, 544, 550, 570, 572, 335, and 336, the processors 512, 522 may be configured to implement part or all of the features described herein.

[0102] In addition, as described herein, the processors 512, 522 may include one or more processing elements. Thus, the processors 512, 522 may include one or more integrated circuits (ICs) configured to perform the functions of the processors 512, 522. In addition, each integrated circuit may include circuits (e.g., first circuits, second circuits, etc.) configured to perform the functions of the processors 512, 522.

[0103] In some aspects, the cellular communication circuit 330 may include only one transmit / receive chain. For example, the cellular communication circuit 330 may not include the modem 520, the RF front end 540, the DL front end 560, and / or the antenna 335b. As another example, the cellular communication circuit 330 may not include the modem 510, the RF front end 530, the DL front end 550, and / or the antenna 335a. In some aspects, the cellular communication circuit 330 may also not include the switch 570, and the RF front end 530 or the RF front end 540 may communicate with the UL front end 572, for example, directly.

[0104] Exemplary Network Elements

[0105] Figure 6 An exemplary block diagram of a network element 600 according to some aspects is shown. According to some aspects, the network element 600 may implement one or more logical functions / entities of a cellular core network, such as a mobility management entity (MME), a serving gateway (S-GW), an access and management function (AMF), a session management function (SMF), a network slice quota management (NSQM) function, etc. It should be noted that Figure 6The network element 600 is only one example of a possible network element 600. As shown, the core network element 600 may include one or more processors 604 that may execute program instructions of the core network element 600. The processor 604 may also be coupled to a memory management unit (MMU) 640 (which may be configured to receive addresses from the processor 604 and translate these addresses into locations in memory (e.g., memory 660 and read-only memory (ROM) 650)), or to other circuits or devices.

[0106] The network element 600 may include at least one network port 670. The network port 670 may be configured to couple to one or more base stations and / or other cellular network entities and / or devices. The network element 600 may communicate with a base station (e.g., eNB / gNB) and / or other network entities / devices by means of any of a variety of communication protocols and / or interfaces.

[0107] As further described later herein, network element 600 may include hardware and software components for implementing or supporting implementations of the features described herein. Processor 604 of core network element 600 may be configured to implement or support implementations of part 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 604 may be configured as a programmable hardware element such as an FPGA (field programmable gate array) or as an ASIC (application-specific integrated circuit) or a combination thereof.

[0108] Resource signal measurement conflict avoidance scheme

[0109] Now go to FIG. 7A to FIG. 7B , according to some aspects, an example timeline 700 / 750 of periodic CSI-RS (P-CSI-RS) and semi-persistent CSI-RS (SP-CSI-RS) for L1-RSRP measurement is shown. Fig. 7A The top timeline in FIG. 7 reflects the number of four consecutive SSB-based radio resource management (RRM) measurement timing configuration windows (i.e., SMTC) or L3 RRM measurement opportunity windows 705. The windows 705 are consecutively labeled 1, 2, 3, 4, and each window is separated by a time period with a period T (710). Although for illustration purposes, the top timeline in FIG. 7 shows the number of consecutive SSB-based radio resource management (RRM) measurement timing configuration windows (i.e., SMTC) or L3 RRM measurement opportunity windows 705. The windows 705 are consecutively labeled 1, 2, 3, 4, and each window is separated by a time period with a period T (710). Fig. 7A Four SMTC or L3 RRM measurement windows are shown in FIG. 1 , but it should be understood that additional measurement windows (eg, 5 or 6 or more measurement windows) may be utilized in the calculation of a single L3 RS measurement (eg, via a time averaging operation).

[0110] Fig. 7AThe bottom timeline in reflects the periodic (P) or semi-persistent (SP) CSI-RS L1-RSRP measurement opportunity windows 720. The windows 720 are also consecutively labeled 1, 2, 3, 4, and each window is separated by a time period with the same period T as the SMTC / L3 measurement opportunity window 705. The L1-RSRP measurement is a measurement activity of beam management (BM) in NR. Because the measurement opportunity windows of SMTC / L3 and L1-RSRP may conflict (i.e., overlap each other in the time domain), it is important to establish a sharing principle so that each type of RS can be fully monitored by the UE.

[0111] For example, the main sharing principles established in NR include: (1) L1-RSRP cannot be performed during the measurement gap (MG) duration; (2) if the L1-RSRP RS opportunity partially overlaps with the SMTC or L3 measurement, the L1-RSRP measurements for those opportunities should be performed outside the SMTC / L3 measurement window; and (3) if the L1-RSRP RS measurement window completely overlaps with the SMTC / L3 measurement window, the L1-RSRP measurement can use 1 out of every n opportunities (where, for example, n = 2 or 3, or some other integer), while the L3 measurement will use the other n-1 opportunities in the time domain.

[0112] However, these sharing principles are mainly used for L1-RSRP cases based on P-CSI-RS or SP-CSI-RS, because P-CSI-RS or SP-CSI-RS may be periodically available in the time domain. For example, if the UE chooses to perform L3 RS measurements instead of L1-RSRP measurements in one or more measurement window opportunities, the UE may still have the opportunity to perform L1-RSRP measurements in some other measurement window opportunities in the time domain.

[0113] exist Fig. 7A In the specific example shown, the L3 and L1 measurement window opportunities completely overlap each other (i.e., they coincide in the time domain at each measurement window opportunity). Therefore, according to some aspects, the UE may use measurement window opportunity 3 (730) to perform L1-RSRP measurements and silence the L1-RSRP measurements at opportunities 1 (7251) and 2 (7252), so the scaling factor P of the L1-RSRP measurement delay in this example will be P=3. In other words, the third L3 measurement window opportunity (715) is silenced (i.e., canceled or fails), which means that the UE must wait for 3 periods before completing its L1-RSRP measurement at measurement window opportunity 3 (730). (Note: the first waiting period is not in Fig. 7A is shown in the Fig. 7AThe period before the first measurement opportunity window 705 / 720 shown in the timeline example of FIG. 7 and marked with "1").

[0114] Now go to Figure 7B , timeline 750 shows the SMTC / L3 measurement opportunity window 755 with Fig. 7A The same period T occurs in the scenario where the periodic (P) or semi-persistent (SP) CSI-RS L1-RSRP measurement opportunity window 760 has a shorter period (770), in which case the shorter period is defined as T / 2. Therefore, the possible P-CSI-RS or SP-CSI-RS measurement opportunity window is twice the SMTC / L3 measurement opportunity window. Therefore, according to some aspects, the UE may determine to perform L1-RSRP measurements outside the SMTC / L3 measurement window. In other words, in Figure 7B In the example, the value of the scaling factor P for the L1-RSRP measurement delay is 2 (i.e., the UE must wait for 2 cycles before completing its L1-RSRP measurement, for example, performing measurements at measurement window opportunities 2 (7652), 4 (7654), 6 (7656), etc., and canceling its L1-RSRP measurement at measurement window opportunities 1 (7651), 3 (7653), 5 (7655), etc.).

[0115] Now go to Figure 8 , according to some aspects, an exemplary timeline 800 of aperiodic CSI-RS (AP-CSI-RS) for L1-RSRP measurement is shown. Fig. 7A / Figure 7B Similarly, the SMTC / L3 measurement opportunity window 805 occurs with the same period T, but the L1-RSRP measurement opportunity window is non-periodic, i.e., as shown by AP-CSI-RS (820). As can now be understood, when the CSI-RS used for L1-RSRP measurement is AP-CSI-RS, there is no need to distinguish between fully or partially overlapping L3 / L1 measurement window opportunities, and if the UE chooses to silence the AP-CSI-RS measurement that conflicts with the L3 RRM measurement window, it also has no other opportunity or chance to perform its L1-RSRP measurement, as shown at the AP-CSI-RS measurement window opportunity 820 where the L1-RSRP is silenced (unless, as will be described in more detail below, the network reconfigures the UE's AP-CSI-RS for L1-RSRP measurement to occur at a different time). To address this issue, it is desirable to clearly define default UE behavior so that the UE can perform reasonable measurement activities on the available RS.

[0116] Now go to FIG. 9A to FIG. 9B, according to some aspects, an exemplary timeline 900 / 950 for configuring a wireless network to avoid conflicts between AP-CSI-RS measurement window opportunities for L1-RSRP and L3 RS measurement window opportunities is shown. As described above, in some aspects, it may be desirable for the network to configure AP-CSI-RS measurements and / or L3 measurements for L1-RSRP to avoid conflicts in the time domain. Fig. 9A As shown in the top line of the timeline 900, the SMTC / L3 measurement opportunity windows 905 occur with the same period T (910), and the L1-RSRP measurement opportunity windows are aperiodic, for example, the AP-CSI-RS measurement opportunity windows 915 for L1-RSRP. Fig. 9A In the example shown, the network has determined to mute only the first window 9201 of the L3 RS measurement opportunity windows. By silencing this single L3 RS measurement opportunity 9201, L3 RS measurements can still be performed in the remaining measurement opportunity windows that do not conflict with the AP-CSI-RS measurement opportunity for L1-RSRP, such as L3 RS measurement opportunity windows 9202, 9203, and 9204, etc. As will be explained in further detail below, the network may also change the timing (e.g., in terms of periodicity, start time, offset, etc.) of the L3 measurement opportunity and / or the AP-CSI-RS measurement opportunity for L1-RSRP to avoid conflict with the AP-CSI-RS for L1-RSRP.

[0117] In contrast, Fig. 9B In the example of the timeline 950 shown, all L3 RS measurement opportunity windows 955 are muted due to conflicts with AP-CSI-RS measurement opportunities 970 for L1-RSRP (i.e., in this case, the network has separately configured multiple AP-CSI-RS for L1-RSRP, each of which happens to conflict with an L3 RS measurement opportunity window). In this case, the L3 RS measurement will fail due to the inability to obtain sufficient measurements, and therefore, the network should try to avoid such configurations if possible.

[0118] Exemplary UE and NW methods for resource signal measurement conflict avoidance

[0119] First go to Fig. 10AAccording to some aspects, a flowchart 1000 is shown that details an exemplary method for UE behavior for handling conflicts between AP-CSI-RS measurements for L1-RSRP and periodic L3 RS measurements. The method 1000 may begin when the UE determines that its AP-CSI-RS measurement opportunity for L1-RSRP overlaps with one or more L3 reference signal (RS) measurement opportunities (step 1002). According to some aspects, at step 1004, at least one of the one or more L3 RS measurement opportunities may include: one or more synchronization signal block (SSB) symbols or CSI-RS symbols for L3 RS measurement (step 1006); one data symbol before the SSB or CSI-RS symbol and one data symbol after the SSB or CSI-RS symbol (step 1008); or one or more received signal strength indication (RSSI) symbols and one data symbol before and after each RSSI symbol (step 1010).

[0120] Next, the method 1000 may determine that the UE cannot measure both the AP-CSI-RS measurement occasion for L1-RSRP and one or more overlapping L3 RS measurement occasions (step 1012). If operating in frequency range 1 (FR1) (i.e., between 410 MHz and 7125 MHz), the UE may not be able to receive both RSs simultaneously, for example, because a mixed parameter set cannot be supported, which would be required due to the different subcarrier spacing (SCS) typically used between the AP-CSI-RS for L1-RSRP measurement and the RS for L3 measurement. If operating in frequency range 2 (FR2) (i.e., between 24250 MHz and 52600 MHz), it may be assumed that the UE cannot receive both RSs simultaneously due to Rx beam differences (e.g., L1 may use a different beam than L3 and the UE may not be able to receive both signals simultaneously). There may also be other reasons why the UE cannot receive both RSs simultaneously.

[0121] Finally, at step 1014, method 1000 may prioritize measurements of AP-CSI-RS for L1-RSRP by the UE over measurements of one or more overlapping L3 RS measurement opportunities. For example, according to some aspects, the UE may prioritize according to a scaling factor P (step 1016). As described above, according to some aspects, the scaling factor P may include a multiple of the period of the L3 RS or L1-RSRP measurement opportunity. For example, the value of the scaling factor may be P=1, or 2, or 3 (etc.), which means that the UE will wait for 1, or 2, or 3 measurement opportunities, respectively, to perform L1-RSRP measurements. According to other aspects, the UE may mute at least one L3 RS measurement opportunity (step 1018). For example, according to some aspects, by silencing at least one L3 RS measurement opportunity, the UE may ensure that AP-CSI-RS for L1-RSRP is received in at least one overlapping measurement opportunity (step 1018). The operation of method 1000 may then continue by returning to step 1002 and continuing to monitor RS measurement conflicts as long as the UE is actively attempting to perform RS measurements.

[0122] Now go to Fig. 10B , according to some aspects, a flowchart 1020 is shown that details an exemplary method for UE behavior for handling conflicts between AP-CSI-RS measurements for L1-RSRP and measurement gaps (MGs). The method 1020 may begin by determining that the UE's AP-CSI-RS for L1-RSRP measurements overlaps with one or more MG opportunities (step 1022). Next, that is, in response to determining that the UE's AP-CSI-RS for L1-RSRP measurements overlaps with one or more measurement gap opportunities, the method 1020 may prioritize the overlapping MG opportunities over the AP-CSI-RS measurement opportunities for L1-RSRP by the UE (i.e., rather than simply shifting or delaying the L1-RSRP measurements) (step 1024). According to some aspects, this prioritization may require, for example, completely silencing or canceling the L1-RSRP measurements.

[0123] FIG. 11A to FIG. 11B is a flow chart illustrating various exemplary methods of network behavior for handling conflicts between AP-CSI-RS measurements for L1-RSRP and periodic L3 RS measurements according to some aspects. Fig.11A, method 1100 may begin with a determination by a wireless network (NW) that a UE cannot perform both AP-CSI-RS measurement and L3 RS measurement for L1-RSRP in an overlapping measurement opportunity (step 1102). Next, in response to determining that the UE cannot perform both AP-CSI-RS measurement and L3 RS measurement for L1-RSRP in an overlapping measurement opportunity, the NW may configure an AP-CSI-RS or L3 RS for L1-RSRP to avoid overlapping measurement opportunities (step 1104). For example, according to some aspects, the NW may avoid overlapping measurement opportunities by configuring the AP-CSI-RS or L3 RS measurement for L1-RSRP so that the AP-CSI-RS avoids overlapping with a synchronization signal block (SSB) symbol or CSI-RS symbol for L3 RS measurement in the time domain (step 1106); configuring the AP-CSI-RS or L3 measurement RS for L1-RSRP to avoid overlapping with one data symbol before and one data symbol after the SSB or CSI-RS symbol (step 1108); and / or configuring the AP-CSI-RS or L3 measurement RS for L1-RSRP to avoid overlapping with one or more received signal strength indication (RSSI) symbols and one data symbol before and after each of the one or more RSSI symbols (step 1110). The operation of method 1100 may then continue by returning to step 1102 and, for example, the NW continues to monitor RS measurement conflicts as long as there are UEs actively attempting to make RS measurements.

[0124] Now go to Fig. 11B , another method 1120 of network behavior for handling conflicts between AP-CSI-RS measurements for L1-RSRP and periodic L3 RS measurements is shown. First, at step 1122, the method 1120 may begin with a determination by a wireless network (NW) that a UE cannot provide both AP-CSI-RS measurements and L3 RS measurements for L1-RSRP in overlapping measurement opportunities. Next, in response to determining that the UE cannot provide both AP-CSI-RS measurements and L3 RS measurements for L1-RSRP in overlapping measurement opportunities, the NW may configure the AP-CSI-RS or L3 measurement RS for L1-RSRP to allow some overlapping measurement opportunities, but avoid a configuration in which multiple AP-CSI-RS for L1-RSRP measurements overlap with all L3 RS measurement opportunities (e.g., during 5 specific consecutive L3 RS measurement opportunities) within a first time interval (step 1124).

[0125] According to some aspects, configuring the AP-CSI-RS or L3 measurement RS for L1-RSRP may also include changing the timing of at least one of the L3 RS measurement opportunities (step 1126). For example, changing the timing of the L3 RS measurement opportunity may include changing at least one of the following: a period, an offset, a bitmap associated with an SSB in the time domain, or a starting point of the L3 RS measurement opportunity.

[0126] According to other aspects, configuring the AP-CSI-RS or L3 measurement RS for L1-RSRP may also include: for each AP-CSI-RS measurement opportunity for L1-RSRP, determining by the NW whether the AP-CSI-RS measurement opportunity for L1-RSRP will overlap with the L3RS measurement opportunity; and when it is determined that the AP-CSI-RS measurement opportunity for L1-RSRP will overlap with the L3 RS measurement opportunity, changing the timing of the AP-CSI-RS measurement opportunity for L1-RSRP (e.g., via any of the aforementioned timing change methods, such as changing the period, offset, or starting point of the AP-CSI-RS measurement opportunity for L1-RSRP, or a bitmap associated with the SSB in the time domain) so as to avoid L3 RS measurement conflicts of the UE. The operation of method 1120 may then continue by returning to step 1122 and, for example, the NW continuing to monitor RS measurement conflicts as long as there is a UE actively attempting RS measurement.

[0127] It should be noted that the dashed boxes in Figures 10 to 11 of the present application indicate the optional nature of such steps or features. In addition, it should be understood that FIG. 10A to FIG. 10B One or more of the UE-based techniques for avoiding RS measurement conflicts described in detail in FIG. 11A to FIG. 11B Any one or more of the NW-based techniques for avoiding RS measurement conflicts detailed in in order to further improve RS measurements of UEs within a wireless network.
