Description

Technical Field

[0001] Various example embodiments are directed to methods, apparatus, systems, and / or non-transitory computer-readable media for providing advanced adjacent channel leakage rate (ACLR) and / or in-band emission (IBE) measurement reports for enhanced operation utilizing dynamic time division duplex (TDD), full duplex, and / or flexible duplex (FDU) scheduling for user equipment. Background Art

[0002] The fifth generation mobile network (5G) standard, referred to as 5G New Radio (NR), is being developed to provide communications with higher capacity, higher reliability, and lower latency than the 4G Long Term Evolution (LTE) standard.

[0003] The 5G NR standard supports two duplex modes: frequency division duplex (FDD), in which user equipment (UE) devices are scheduled to perform uplink (UL) and downlink (DL) on paired frequency bands in the same time period; and time division duplex (TDD), in which UE devices are scheduled to perform UL and DL on the same frequency band at different times. In addition, the 5G NR standard supports dynamic TDD mode, in which the UL / DL time slots scheduled for UE devices can be dynamically changed by the RAN node. In addition, support for flexible duplex (FDU) mode, and / or full-duplex mode on non-overlapping resources has been proposed, in which the RAN node can perform DL and UL transmissions simultaneously on different physical resource blocks (PRBs) within an unpaired wideband carrier.

[0069] As used in this application, the terms "circuitry" and / or "hardware circuitry" may refer to one or more or all of the following: (a) a pure hardware circuit implementation (such as an implementation in analog and / or digital circuitry only); (b) a combination of hardware circuitry and software, such as (as applicable): (i) a combination of (multiple) analog and / or digital hardware circuits with software / firmware, and (ii) any portion of (multiple) hardware processors (including (multiple) digital signal processors), software, and (multiple) memories with software, which work together to enable a device such as a mobile phone or server to perform various functions); and (c) (multiple) hardware circuits and / or (multiple) processors, such as (multiple) microprocessors or portions of (multiple) microprocessors, which require software (e.g., firmware) to operate, but when not required for operation, the software may not be present. For example, the circuitry may more specifically include, but is not limited to, a central processing unit (CPU), an arithmetic logic unit (ALU), a digital signal processor, a microcomputer, a field programmable gate array (FPGA), a system on a chip (SoC), a programmable logic unit, a microprocessor, an application specific integrated circuit (ASIC), etc.

[0070] This definition of circuitry applies to all uses of the term in this application, including in any claims. As another example, as used in this application, the term circuitry also covers an implementation of only a hardware circuit or processor (or multiple processors) or a portion of a hardware circuit or processor and its accompanying software and / or firmware. For example, if applicable to a particular claim element, the term circuitry also covers a baseband integrated circuit or processor integrated circuit for a mobile device, or a similar integrated circuit in a server, cellular network device, or other computing or network device.

[0071] Although various example embodiments of the present disclosure are discussed in conjunction with the 5G wireless communication standard for the sake of clarity and convenience, the example embodiments are not limited thereto, and a person of ordinary skill in the art will recognize that the example embodiments may be applicable to other wireless communication standards, such as the 4G standard, the Wi-Fi standard, the future 6G standard, the future 7G standard, etc.

[0072] Various example embodiments are directed to improving adjacent channel leakage rate (ACLR) and / or in-band emission (IBE) measurement reports generated by UE devices; and using improved and / or advanced ACLR and / or IBE measurement reports to provide enhanced UE scheduling by RAN nodes using dynamic time division duplexing (TDD) and / or flexible duplexing (FDU) (which may also be referred to as sub-band non-overlapping full duplexing). As currently defined in 5G standards, and as Figure 1B As shown in ( Figure 1BExample FDD, TDD, and FDU resource partitions are illustrated), and UE devices can be scheduled to perform duplex communications (e.g., both UL and DL) in both the frequency domain (FDD) and the time domain (TDD). Figure 1B As shown in , when the UE is configured for FDD, the UE is assigned a paired frequency band, such as a UL carrier and a DL carrier, with a guard band between the UL carrier and the DL carrier, and the UE can send and receive data on the UL carrier and the DL carrier at the same time (e.g., perform full-duplex communication). In the case of TDD, the UE device is assigned a single carrier frequency, and the UE performs UL and DL on the single carrier frequency but at different non-overlapping time slots, such as Figure 1B As shown in , or in other words, the UE performs half-duplex communication with the RAN node, while the RAN node is capable of full-duplex communication by receiving data from the first UE on a first carrier frequency and simultaneously sending data to the second UE on a second carrier frequency.

[0073] In addition, the 5G standard also supports dynamic TDD, in which RAN nodes perform dynamic assignment and / or reassignment of time domain resources to individual UE devices based on demand, for example, assigning UE devices more or less UL time slots for a given radio frame, etc. However, due to the increased likelihood of UE-to-UE cross-link interference (CLI) and issues associated with inter-operator RAN nodes operating in adjacent wireless channels in overlapping service areas (e.g., base station (BS) to BS CLI), performance degradation will make dynamic TDD infeasible in the real world if different operator RAN nodes do not use the same TDD configuration.

[0074] In addition, flexible duplex (FDU) and / or sub-band non-overlapping full-duplex techniques are currently being studied, where a RAN node can simultaneously transmit to a first UE and receive from a second UE on non-overlapping frequency resources of the same unpaired carrier. However, even with FDU, the UE still operates in half-duplex mode, for example, the same UE device cannot be assigned DL and UL simultaneously on different PRBs. However, with FDU, the first UE may also suffer from UE-to-UE CLI from non-overlapping frequency resources, where the CLI is generated by a second UE served by the same RAN node sending UL when the first UE is receiving in DL, and vice versa.

[0075] In addition, 3GPP defines the maximum power reduction (MPR) requirement allowed as the maximum (e.g., worst-case) power reduction required to meet specified emission requirements (e.g., ACLR, IBE, out-of-band emissions (OOBE), and spurious emissions), as well as other requirements (such as error vector magnitude (EVM) requirements, etc.). In the context of example embodiments, the term emission (or more specifically, undesired and / or undesired emission) refers to interference caused by a radio frequency (RF) transmission (e.g., UL transmission) performed by a transmitting device (e.g., UE device, RAN node, etc.) using a first set of frequency resources (e.g., a set of desired, assigned, allocated and / or scheduled PRBs) on a second set of frequency resources. The second set of frequency resources is different from the first set of frequency resources and does not overlap (e.g., non-overlapping). IBE can be considered as the difference between an ideal and / or expected waveform formed by an RF transmission (e.g., UL transmission) and an actual measured waveform of the RF transmission of the allocated resource block. IBE is defined as the ratio of the UE output power in the non-allocated PRBs to the UE output power in the allocated RBs. OOBE may be considered an undesired and / or unintended RF emission and / or transmission that causes interference to frequency resources outside of the desired, assigned, allocated and / or scheduled frequency resources (eg, PRBs) of the transmitting device.

[0076] In practice, depending on several factors such as channel bandwidth, UL RB allocation, UE transmit power, etc., a UE is often able to operate (well) below at least some specified transmission requirements.

[0077] Thus, one or more example embodiments provide improvements to UE scheduling by providing advanced ACLR and / or IBE measurement reports generated by UE devices, including improved in-band and / or out-of-band emission measurements, thereby allowing a RAN node to determine potential interference caused by the UE device and adjust dynamic time division duplex (TDD) and / or flexible duplex (FDU) scheduling of the UE device based on the determined potential interference. By having the UE report measured adjacent channel and / or in-band emissions, as well as information about at least one of the allocated PRBs and UE UL transmit power used when performing the measurements, the RAN node can obtain, for each reporting UE, more detailed and / or more precise information about adjacent channel emissions (e.g., OOBE) and / or in-band emissions generated by the UE at a particular frequency offset (compared to what the RAN node can assume from emission requirements available in 3GPP and / or 5G NR specifications), as a function of, among other things, the allocated PRBs and UE transmit power. This information may be used at the RAN node when scheduling users and / or UEs during sub-band full duplex (SBFD) timeslots and / or CLI timeslots for FDU and dynamic TDD, respectively.

[0078] Therefore, the UE device can be scheduled to use dynamic TDD and / or FDU, thereby improving network resource usage efficiency, improving network reliability, and / or improving duplex performance, etc.

[0080] The RAN nodes 110 to 130, and / or the UE devices 140 to 160 may be connected via a wireless network, such as a cellular wireless access network (e.g., a 3G wireless access network, a 4G long term evolution (LTE) network, a 5G new radio (e.g., 5G) wireless network, a 6G wireless network, a WiFi network, etc.). The wireless network may include a core network 100 and / or a data network 105.

The data network 105 may refer to the Internet, an intranet, a wide area network, etc.

[0081] According to some example embodiments, the RAN nodes 110, 120, 130 may act as relay nodes (e.g., integrated access and backhaul (IAB) nodes) and may be combined with at least one base station (and / or access point (AP), router, etc.) (not shown) of the same or different radio access technology (e.g., WiFi, etc.) to communicate with UE devices 140, 150, 160, etc.

UE devices 140, 150, 160 may be configurable to send and / or receive data according to strict latency, reliability, and / or accuracy requirements, such as URLLC communications, TSC communications, etc., but example embodiments are not limited thereto.

[0083] The wireless communication system also includes multiple transmission / reception points (TRPs) (e.g., base stations, wireless access points, etc.), such as RAN nodes 110 to 130, etc. The RAN nodes 110, 120, 130, etc. can operate according to the underlying cellular and / or wireless radio access technology (RAT), such as 5G NR, LTE, Wi-Fi, etc. For example, the RAN nodes 110, 120, 130, etc. can be 5G gNB nodes, LTE eNB nodes, or LTE ng-eNB nodes, etc., but the example embodiments are not limited to this. The RAN nodes 110, 120, 130, etc. can provide wireless network services to one or more UE devices within one or more cells (e.g., cell service areas, broadcast areas, service areas, coverage areas, etc.) around the corresponding physical location of the RAN node. As Figure 1A As shown in , RAN node 110 may provide cell 110A, RAN node 120 may provide cell 120A, and / or RAN node 130 may provide cell 130A, but example embodiments are not limited thereto.

For example, UE device 140 may perform carrier aggregation using one or more CCs from both RAN nodes 110 and 120, or may perform carrier aggregation using two or more CCs from a single RAN node (e.g., RAN node 110 or RAN node 120), etc., but example embodiments are not limited thereto.

[0086] According to at least one example embodiment, UE device 140, etc. may include multiple antenna panels (e.g., may be a multi-panel UE device, etc.), and may use the same time-frequency resources and / or use time-overlapping resources to transmit and / or receive to multiple RAN nodes (e.g., TRPs) (such as RAN nodes 110 to 130, etc.), but example embodiments are not limited thereto. For example, UE device 140 may perform UL transmission to one or more RAN nodes among RAN nodes 110 to 130, etc., and may measure an in-band emission (IBE) leakage level and / or an out-of-band emission (OOBE) leakage level (e.g., adjacent channel transmission, etc.) corresponding to the UL transmission.

[0089] Figure 2 A block diagram of an example RAN node is illustrated according to at least one example embodiment. Figure 2 The RAN node may correspond to Figure 1A RAN nodes 110, 120, and / or 130, but example embodiments are not limited thereto.

[0090] refer to Figure 2 , the RAN node 2000 may include a processing circuit system, such as at least one processor 2100, at least one communication bus 2200, a memory 2300, at least one core network interface 2400, and / or at least one wireless antenna array 2500, etc., but the example embodiments are not limited thereto. For example, the core network interface 2400 and the wireless antenna array 2500 may be combined into a single network interface, etc., or the RAN node 2000 may include multiple wireless antenna arrays, multiple core network interfaces, etc., and / or any combination thereof. The memory 2300 may include various dedicated program codes, including for executing Figures 4 to 5 The computer executable instructions may enable the RAN node 2000 to perform one or more of the methods of the example embodiments, but the example embodiments are not limited thereto.

[0091] In at least one example embodiment, the processing circuit system may include at least one processor (and / or processor core, distributed processor, networked processor, etc.), such as at least one processor 2100, which may be configured to control one or more elements of the RAN node 2000 and thereby cause the RAN node 2000 to perform various operations. The processing circuit system (e.g., at least one processor 2100, etc.) is configured to perform processing by retrieving program code (e.g., computer-readable instructions) and data from the memory 2300 to execute them, thereby performing dedicated control and functions of the entire RAN node 2000. Once the dedicated program instructions are loaded into (e.g., at least one processor 2100, etc.), the at least one processor 2100 executes the dedicated program instructions, thereby converting the at least one processor 2100 into a dedicated processor.

[0092] In at least one example embodiment, the memory 2300 may be a non-transitory computer-readable storage medium and may include a random access memory (RAM), a read-only memory (ROM), and / or a permanent mass storage device, such as a disk drive or a solid-state drive. Stored in the memory 2300 are program codes (i.e., computer-readable instructions) related to the operation of the RAN node 2000, such as in conjunction with Figures 4 to 5 , at least one core network interface 2400 and / or at least one wireless antenna array 2500, etc. Such software elements may be loaded from a non-transitory computer-readable storage medium independent of the memory 2300 using a driver mechanism (not shown) connected to the RAN node 2000, or via at least one core network interface 2400 and / or at least one wireless antenna array 2500, etc.

[0093] In at least one example embodiment, the communication bus 2200 may enable communication and data transfer between elements of the RAN node 2000. The bus 2200 may be implemented using a high-speed serial bus, a parallel bus, and / or any other suitable communication technology. According to at least one example embodiment, the RAN node 2000 may include multiple communication buses (not shown), such as an address bus, a data bus, etc.

[0094] The RAN node 2000 may operate as, for example, a 4G RAN node, a 5G RAN node, etc., and may be configured to schedule time domain resource allocation (TDRA), such as orthogonal frequency division multiplexing (OFDM) symbols, physical resource blocks (PRBs), resource elements, etc., for UE devices connected to the RAN node 2000, but example embodiments are not limited thereto.

[0095] For example, RAN node 2000 may allocate time-frequency resources (e.g., component carriers) of carriers (e.g., resource blocks with time and frequency dimensions) based on operations in the time domain (e.g., time division duplexing) and / or frequency domain (e.g., frequency division duplexing). In the context of the time domain, RAN node 2000 will allocate carriers (or subbands of carriers) to one or more UEs (e.g., UE 140, 150, 160, etc.) connected to RAN node 2000 during a specified upload (e.g., uplink (UL)) time period and a specified download (e.g., downlink (DL)) time period, or during a specified special (S) time period that can be used for UL and / or DL, but example embodiments are not limited thereto. In addition, according to some example embodiments, RAN node 2000 may schedule one or more UEs according to dynamic TDD and / or flexible duplexing, etc., but example embodiments are not limited thereto.

[0096] When multiple UEs are connected to the RAN node 2000, the carrier is shared in time so that each UE is scheduled by the RAN node 2000, and the RAN node 2000 allocates its own uplink time and / or downlink time to each UE. In the frequency domain context, and / or when performing spatial domain multiplexing of UEs (e.g., MU MIMO, etc.), the RAN node 2000 will allocate a separate frequency subband (e.g., physical resource block, etc.) of the carrier to the UEs simultaneously served by the RAN node 2000 for uplink and / or downlink transmission, with a guard band between the UL frequency band and the DL frequency band. Data transmission between the UE and the RAN node 2000 can be performed on a radio frame basis in both the time domain context and the frequency domain context. The minimum resource unit allocated and / or assigned by the RAN node 2000 to a specific UE device corresponds to a specific downlink / uplink time interval (e.g., one OFDM symbol, one time slot, one mini-time slot, one subframe, etc.) and / or a specific downlink or uplink resource block (e.g., twelve adjacent subcarriers, frequency subbands, etc.). The RAN node 2000 can schedule and / or assign different transmission frame formats, typically used in TDD systems, but not limited thereto, wherein each frame format contains a desired sequence of DL, S and / or UL time slots in a desired pattern and / or sequence. However, when a UE (such as UE 140) (by the core network 100 and / or the RAN node 2000, etc.) is configured to employ carrier aggregation, the UE 140 can simultaneously send / receive data from multiple component carriers (CCs), etc. For clarity and consistency, the example embodiments will be primarily described as using the time domain, but the example embodiments are not limited thereto.

[0097] In addition, the RAN node 2000 may send scheduling information to one or more UE devices located in the cell service area of ​​the RAN node 2000 via physical downlink control channel (PDCCH) information, and the scheduling information may configure the one or more UE devices to send (e.g., UL transmission via physical uplink control channel (PUCCH) information and / or physical uplink shared channel (PUSCH) information, etc.) and / or receive (e.g., DL transmission via physical downlink shared channel (PDSCH) information, etc.) data packets to the RAN node 2000. In addition, the RAN node 2000 may send control messages to the UE devices via physical (PHY) layer signaling, medium access control (MAC) layer control element (CE) signaling, radio resource control (RRC) signaling, etc. using downlink control information (DCI) messages, but example embodiments are not limited thereto.

[0098] RAN node 2000 may also include at least one core network interface 2400 and / or at least one wireless antenna array 2500, etc. At least one wireless antenna array 2500 may include an associated radio unit array (not shown) and may be used to transmit wireless signals, such as 4G LTE wireless signals, 5G NR wireless signals, etc., to at least one UE device (such as UE 140, etc.) according to a radio access technology. According to some example embodiments, wireless antenna array 2500 may be a single antenna or may be a plurality of antennas, etc. For example, wireless antenna array 2500 may be configured as a beam grid (GoB), and the GoB transmits a plurality of beams in different directions, angles, frequencies, and / or different delays, etc., but example embodiments are not limited thereto.

[0099] The RAN node 2000 may communicate with a core network (e.g., a backend network, a backhaul network, a backbone network, a data network, etc.) of a wireless communication network via a core network interface 2400. The core network interface 2400 may be a wired and / or wireless network interface, and may enable the RAN node 2000 to communicate and / or send data with a network device on a backend network, such as a core network gateway (not shown), a data network (e.g., the data network 105), such as the Internet, an intranet, a wide area network, a telephone network, a VoIP network, etc.

[0100] although Figure 2An example embodiment of a RAN node 2000 is depicted, but the RAN node is not limited thereto and may include additional and / or alternative architectures that may be suitable for the purposes shown. For example, the functionality of the RAN node 2000 may be divided between multiple physical, logical and / or virtual network elements, such as a centralized unit (CU), a distributed unit (DU), a remote radio head (RRH) and / or a remote radio unit (RRU), etc. In addition, the RAN node 2000 can operate in a standalone (SA) mode and / or a non-standalone (NSA) mode, which uses an interface (not shown) between the RAN node 2000 and other RAN nodes of the wireless network (such as X2, Xn, etc.), an interface between the RAN node 2000 and the core network (e.g., the core network 100) (such as S1, NG, etc.), an interface between network functions of the RAN node 2000 operating in a distributed and / or virtual RAN mode (such as F1, E1, etc.), and / or an interface (not shown) between the physical layer (e.g., a baseband unit, etc.) and the radio layer (e.g., RRH, core network interface 2400, etc.) (such as CPRI, eCPRI, etc.), but the example embodiments are not limited thereto.

[0103] In at least one example embodiment, the processing circuit system may include at least one processor (and / or processor core, distributed processor, networked processor, etc.), such as at least one processor 3100, which may be configured to control one or more elements of the UE 3000 and thereby cause the UE 3000 to perform various operations. The processing circuit system (e.g., at least one processor 3100, etc.) is configured to perform processing by retrieving program code (e.g., computer-readable instructions) and data from the memory 3300 to execute them, thereby performing dedicated control and functions of the entire UE 3000. Once the dedicated program instructions are loaded into the processing circuit system (e.g., at least one processor 3100, etc.), the at least one processor 3100 executes the dedicated program instructions, thereby converting the at least one processor 3100 into a dedicated processor.

Stored in memory 3300 are program codes (i.e., computer-readable instructions) related to the operation of UE 3000, such as in conjunction with Figures 4 to 5Such software elements may be loaded from a non-transitory computer-readable storage medium independent of the memory 3300 using a driving mechanism (not shown) connected to the UE 3000, or via multiple wireless antennas 3400, etc. In addition, the memory 3300 may store network configuration information, such as system information, resource block scheduling, etc., for communicating with at least one RAN node (e.g., RAN nodes 110, 120, 130, etc.), accessing a wireless network, etc., but example embodiments are not limited thereto.

[0105] In at least one example embodiment, at least one communication bus 3200 may enable communication and data transmission / reception between elements of UE 3000, and / or monitor the status of elements of UE 3000 (e.g., monitoring transmission power level, monitoring interference level, monitoring channel quality level, etc.).

According to at least one example embodiment, UE 3000 may include multiple communication buses (not shown), such as an address bus, a data bus, etc.

[0106] The UE 3000 may also include, but is not limited to, multiple wireless antenna panels 3400. The multiple wireless antenna panels 3400 may include multiple related radio units (e.g., Figure 3B RF transmitter 3410) and the like, and can be used to send wireless signals according to at least one desired radio access technology (such as 4G LTE, 5G NR, Wi-Fi, etc.). In addition, multiple wireless antenna panels 3400 can be configured to send and / or receive data communications to one or more RAN nodes (e.g., RAN nodes 110, 120, 130, etc.), but example embodiments are not limited thereto. Multiple wireless antenna panels 3400 can be located at the same or different physical locations on the body of UE 3000, can have the same or different orientations, can operate in the same or different frequency ranges, can operate according to the same or different radio access technologies, and the like. According to some example embodiments, multiple wireless antenna panels 3400 can be a single antenna, or can be multiple antennas, and the like.

[0107] UE 3000 may also include a feedback receiver 3500, but example embodiments are not limited thereto, for example, feedback receiver 3500 may be included in wireless antenna panel 3400, etc. Feedback receiver 3500 may measure in-band emissions (IBE) corresponding to and / or associated with UL transmissions performed by UE 3000, such as a ratio of UE output power (e.g., UL transmission power) in non-allocated resource blocks to UE output power in allocated resource blocks, general transmission (applicable to all non-allocated PRBs), in-phase and quadrature-phase (IQ) image component transmissions, and carrier leakage, etc., but example embodiments are not limited thereto. In addition, feedback receiver 3500 may measure out-of-band emissions (OOBE) corresponding to and / or associated with UL transmissions (such as ACLR, etc.), but example embodiments are not limited thereto. For example, ACLR measurement is a ratio of filtered average power centered on the assigned channel frequency to filtered average power consumption centered on the adjacent channel frequency. The adjacent channel frequency can be set by the 5G standard based on the power class and / or power level of the UE device, and / or can be configured to an expected frequency offset value by the network (e.g., core network 100, RAN node 110, etc.) via measurement parameters included in a transmission report configuration sent by RAN node 110, but the example embodiments are not limited thereto.

The IQ demodulator 3512 may convert the modulated RF signal into an in-phase / quadrature phase (I / Q) signal, such as a zero IF signal or the like, but is not limited thereto. The zero IF signal is then filtered using a filter 3513 (e.g., a low pass filter, etc.) to remove unwanted mixing byproducts and / or noise, and is then digitized by a zero IF analog-to-digital converter circuit 3514 or the like to have at least 3 times the signal bandwidth and a desired amount of dynamic range in order to detect information about leakage of a transmit signal on an adjacent channel (e.g., OOBE leakage level, etc.), but the example embodiment is not limited thereto, and for example, other bandwidth and / or dynamic range values ​​may be used. The digitized signal is then output to the adaptive predistortion circuit 3411, which compares the digitized signal with the original baseband data to determine the amount of transmit signal error in the output signal, etc. The adaptive predistortion circuit 3411 may then output the determined transmit signal error to the processor 3100 of the UE 3000, and may also adjust the data signal input to the RF modulator 3412 based on the determined transmit signal error, etc.

[0113] According to at least one example embodiment, in operation S4010, a RAN node (such as Figure 1A RAN node 110, etc.) may be a UE device (such as Figure 1A The example embodiments may include, but are not limited to, a UE 140 (e.g., UE 140 of the embodiment of the present invention) configuring a transmission report configuration setting (e.g., ALCR / IBE measurement report setting, etc.), but example embodiments are not limited thereto. The transmission report configuration setting may include, but are not limited to, at least one measurement parameter and / or at least one transmission report triggering condition. According to some example embodiments, at least one measurement parameter may be a transmission value corresponding to an expected UL transmission measured by UE 140, and may include at least one of an in-band transmission leakage level (IBE measurement, etc.), an out-of-band transmission leakage level (e.g., ALCR measurement, etc.), and / or at least one expected frequency offset value (e.g., an offset between a frequency used to perform UL transmission and a frequency used to measure UL transmission transmission), etc., but are not limited thereto. In addition, the transmission report triggering condition (e.g., measurement trigger, etc.) may be a condition and / or setting that specifies, instructs, and / or configures UE 140 to measure the next UL transmission based on at least one measurement parameter. For example, the transmission report triggering condition may be at least one of the following: an implicit trigger, such as an expected transmission threshold, an expected periodicity setting (e.g., a timer setting, etc.), etc.; and / or an explicit trigger from the network, such as an expected downlink control information (DCI) trigger (e.g., indicating that UE 140 will perform transmission measurement after the next DCI scheduling command received from RAN node 110, etc.; and / or an expected medium access control (MAC) control element (CE) trigger, which indicates that UE 140 performs transmission measurement after receiving the next MAC CE trigger from RAN node 110, etc., but example embodiments are not limited thereto. In addition, according to some example embodiments, UE 140 may be configured to use multiple transmission report triggering conditions, such as two or more of the expected transmission threshold, the expected periodicity setting, the DCI trigger, and / or the MAC CE trigger. The combination of the two or more conditions may be used to generate a transmission report triggering condition. Figure 5 , discusses implicit emission report triggering in more detail.

[0114] Furthermore, according to some example embodiments, if UE 140 is configured to perform carrier aggregation (CA), RAN node 110 may include an indication of one or more carrier components associated with and / or corresponding to the configured CA, for which transmit measurements in the transmit report configuration are to be performed, or in other words, RAN node 110 may configure UE 140 to perform transmit measurements on a subset of carrier components, although example embodiments are not limited thereto. The transmit measurement configuration may also include one or more UL transmission parameters to be reported, such as a power level of a UL transmission being measured (e.g., a UL transmit power level, etc.), an RB allocation corresponding to and / or associated with the UL transmission being measured, (multiple) expected frequency offset values ​​to be measured corresponding to the UL transmission, etc., although example embodiments are not limited thereto.

[0115] In operation S4020, RAN node 110 may send an explicit transmit report trigger, such as a DCI trigger and / or a MACCE trigger, etc., but example embodiments are not limited thereto, and the transmit report trigger may be an implicit trigger, such as a desired measurement time interval, a desired transmit threshold, etc. In the case where the explicit trigger is a DCI trigger, the DCI trigger may be included in a DCI scheduling command that is sent to UE 140 to schedule PUCSCH transmission by UE 140, but example embodiments are not limited thereto. In addition, UE 140 may receive the explicit transmit report trigger, and may determine whether the received explicit transmit report trigger satisfies at least one transmit report trigger condition set in the transmit measurement configuration received in operation S4010.

[0116] Assuming that the transmission report trigger condition sent as part of the measurement report configuration is a DCI trigger condition, and UE 140 receives the DCI trigger from RAN node 110, in operation S4030, the DCI scheduling will cause UE 140 to start preparing for transmission measurement by calculating a transmission power headroom (PHR) of UL transmission, a maximum power reduction (MPR) and / or a carrier maximum power (Pcmax) corresponding to the UL transmission, etc., and storing them in a memory, but example embodiments are not limited thereto. As another example, assuming that the transmission report trigger condition is a MAC CE trigger, in operation S4030, UE 140 may calculate a PHR of UL transmission, an MPR and / or Pcmax corresponding to the UL transmission, etc., and UL RB allocation information associated and / or corresponding to the UL transmission to RAN node 110, and store them in a memory, but example embodiments are not limited thereto.

[0117] The PHR, MPR, and / or Pcmax may indicate to the RAN node 110 what is the available power in the UL transmission time slot. In addition, the UE 140 may store the calculated PHR value, MPR value, Pcmax value, etc. in a memory, but example embodiments are not limited thereto. In some example embodiments, the UE 140 may also store in the memory UL transmission parameters associated and / or corresponding to the scheduled and / or measured UL transmissions, such as the UL RB allocation for the transmission; and / or a specific time reference associated with the UL transmission, such as the HARQ ID and / or HARQ transmission number for the transmission, the SFN for the transmission, the time slot ID and / or the starting OFDM symbol, etc., but example embodiments are not limited thereto.

[0118] In operation S4040, UE 140 may perform UL transmission to RAN node 110 according to at least one transmission parameter (e.g., UL transmission power, UL RB allocation, etc.), but example embodiments are not limited thereto. For example, UE 140 may send the scheduled PUSCH to RAN node 110 according to the DCI scheduling command, or in the case of using MAC CE triggering, UE 140 may wait for the next available PUSCH / PUCH / SRS transmission, etc., but example embodiments are not limited thereto. In operation S4050, UE 140 may use at least one RF sensor (such as feedback receiver 3500, etc.) to perform IBE and / or OOBE measurement corresponding to UL transmission (e.g., PUSCH transmission, PUCCH transmission, sounding reference signal (SRS) transmission, etc.) based on at least one measurement parameter and at least one transmission parameter indicated in the measurement report configuration, but example embodiments are not limited thereto. For example, UE 140 may measure an in-band transmission leakage level (IBE measurement, etc.), an out-of-band transmission leakage level (ALCR measurement, etc.), a signal-to-interference and noise ratio (SINR), a spurious emission level, etc., of a desired and / or scheduled transmission frequency at (multiple) desired frequency offsets from the desired transmission frequency indicated in a measurement parameter, etc., but the example embodiments are not limited thereto.

[0119] Furthermore, according to some example embodiments, if UE 140 is configured to perform CA, UE 140 may perform IBE and / or OOBE measurements on one or more desired carrier components indicated in the transmit measurement report configuration setting, and / or store UL transmission parameters corresponding to one or more UL transmissions. For example, if UE 140 is configured to perform CA on four carrier components, and the transmit measurement report configuration setting indicates that UE 140 is to measure transmissions on a first carrier component and a second carrier component, UE 140 may measure IBE and / or OOBE corresponding to the first carrier component and the second carrier component, etc., but example embodiments are not limited thereto.

[0120] In operation S4060, UE 140 may generate a transmit measurement report based on transmit measurements (e.g., measured IBE leakage levels, measured OOBE leakage levels, SINR, etc.) and / or UL transmission parameters corresponding to the performed UL transmission (such as stored PHR, Pcmax value, MPR value, etc.).

[0121] According to some example embodiments, UE 140 may indicate UL transmission parameters using indices corresponding to multiple combinations of transmission parameters, the UL transmission parameters corresponding to the performed UL transmission. For example, UE 140 may be configured to perform UL transmission using UL parameters forming N×M×S combinations, where N corresponds to possible transmission power levels of the UL transmission (e.g., for N=3, high / medium / low TX power, etc.), M corresponds to a transmission bandwidth (BW) (e.g., for M=3, inner / outer / edge BW or narrow / medium / large BW, etc.), and S corresponds to a desired frequency spacing (e.g., for S=3, image frequency, carrier leakage frequency, X PRBs from the edge of the TX BW, or X / Y / Z PRBs from the edge of the TX BW, etc.), but example embodiments are not limited thereto, for example, N, M and / or S values ​​may be greater than or less than 3, etc.

[0122] In operation S4070, UE 140 may send the generated transmit measurement report to RAN node 110. According to some example embodiments, UE 140 may send the generated transmit measurement report as an RRC message, a MAC CE, or both an RRC message and a MAC CE, etc., but example embodiments are not limited thereto. In addition, UE 140 may send a MAC CE to a distributed unit (DU) of core network 100, and may send an RRC report to a central unit (CU) of core network 100, etc., but example embodiments are not limited thereto. In at least one example embodiment, after receiving the transmit measurement report, the DU may transmit the report back to the CU via an F1 interface, etc., but example embodiments are not limited thereto.

[0123] In operation S4080, RAN node 110 may adjust PRB allocation and / or make new PRB allocation based on the received transmission measurement report. More specifically, RAN node 110 may adjust dynamic TDD and / or FDU scheduling of UE 140 and / or UE devices 150 and / or 160 adjacent to UE 140 based on the received transmission measurement report by estimating potential interference caused by UL transmission of UE 140, etc., but example embodiments are not limited thereto. For example, RAN node 110 may calculate potential interference caused by UE 140 using the following formula:

[0124] Interference(P_tx,f,#rb)=(P_tx / #N_rb)-ACLR(P_tx,f,#rb)[Equation 1];

[0125] Wherein f = frequency offset between Tx and Rx; P_tx = UE Tx power, #rb = ​​allocated frequency resource set; and #N_rb = size of allocated frequency resource, but example embodiments are not limited thereto.

[0126] In addition, the RAN node 110 may adjust UL transmission parameters, such as UL transmission power, UL PRB allocation, etc., based on the calculated potential interference, but is not limited thereto.

[0127] Figure 5 A second transmission flow diagram for generating advanced ACLR and / or IBE measurement reports using an implicit transmit report trigger according to at least one example embodiment is illustrated.

[0128] According to at least one example embodiment, in operation S5010, similar to operation S4010, RAN node 110 may configure a transmission measurement report setting (e.g., ALCR / IBE measurement report setting, etc.) for UE 140, the transmission measurement report setting including at least one measurement parameter and / or at least one transmission report triggering condition, but example embodiments are not limited thereto. More specifically, in Figure 5 In the example, it is assumed that the transmission report triggering condition is set to the expected transmission threshold trigger, but the example embodiments are not limited thereto. For example, in some other example embodiments, UE 140 may be configured to perform transmission measurement reporting on an expected periodic (time) basis, etc., but is not limited thereto.

[0129] According to at least one example embodiment, the desired transmit threshold may correspond to the “worst case interference” caused by UL transmissions of UE 140 interfering with the DL of neighboring UEs (e.g., UEs 150, 160, etc.). UE 140 may calculate the worst case interference using the following formula:

[0130] (P_tx / #N_rb)-ACLR=[(P_max-MPR-PH) / #N_rb-ACLR]>threshold[Equation 2];

[0131] Wherein f=frequency offset between Tx and Rx; P_tx=UE tx power, #rb=allocated frequency resource set, #N_rb=size of allocated frequency resource; and threshold is a desired transmission threshold set by a network or the like, but example embodiments are not limited thereto.

[0132] In operation S5020, similar to S4030, UE 140 may calculate a PHR corresponding to the UL transmission to RAN node 110 and store it in a memory. In addition, UE 140 may also store UL RB allocation information associated with and / or corresponding to the UL transmission to RAN node 110, but example embodiments are not limited thereto. In operation S5030, similar to S4040, UE 140 may perform UL transmission to RAN node 110 based on at least one transmission parameter, etc. In operation S5040, similar to S4050, UE 140 may measure transmission associated with and / or corresponding to the performed UL transmission (e.g., PUSCH transmission, etc.) based on at least one measurement parameter and / or transmission parameter, but example embodiments are not limited thereto. In operation S5050, UE 140 may determine whether the measured UL transmission exceeds the expected transmission threshold set in the transmission measurement report trigger condition, for example, determine whether IBE and / or OOBE exceed the expected IBE transmission threshold and / or the expected OOBE transmission threshold, respectively.

[0133] In operation S5060, similar to S4060, in response to the measured UL transmission exceeding the expected transmission threshold (and / or exceeding the time value of the expected periodic setting (if the transmission report trigger is set to the periodic setting), etc.), UE 140 may generate a transmission measurement report based on the stored PHR and / or the stored UL RB allocation information, and the measured IBE and OOBE corresponding to the performed UL transmission, etc. In the case that the measured UL transmission does not exceed the expected transmission threshold, UE 140 may skip operations S5060 to S5070 and repeat operations S5030 and S5040, etc., but example embodiments are not limited thereto.

[0134] In operation S5070, similar to S4070, UE 140 may send a transmit measurement report, etc. to RAN node 110. In operation S5080, similar to S4080, RAN node 110 may adjust PRB allocation and / or make new PRB allocation associated with dynamic TDD and / or FDU scheduling of UE 140 and / or neighboring UEs 150, 160, etc. based on the received transmit measurement report, but example embodiments are not limited thereto.
