[0003] The following discussion pertains to wireless communications, including early measurements for Minimum Drive Test (MDT) recording, i.e., recording measurements of non-cell reselection frequencies and cells in the recorded MDT report. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, and broadcasting. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth-generation (4G) systems (e.g., Long Term Evolution (LTE) systems, improved LTE (LTE-A) systems, or LTE-A Pro systems) and fifth-generation (5G) systems (which may be referred to as New Radio (NR) systems). These systems can employ technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication with multiple communication devices (which may also be referred to as User Equipment (UE)).

[0047] Some wireless communication systems can support Minimized Drive Testing (MDT) to test the quality of wireless communication in an area. Using MDT, the network can collect radio measurements to autonomously optimize network performance. Some systems can use instantaneous MDT, where user equipment (UE) can be configured to perform measurements and immediately report them to the serving cell. Alternatively, systems can utilize recorded MDT, where the device performs measurements and then later sends a measurement report containing the measurements, where the measurements can be used for recorded MDT purposes. Reports from recorded MDT can include periodic or event-triggered measurements.

[0048] In addition, wireless communication can also support dual-connectivity carrier aggregation (DCCA). To facilitate more efficient or faster DCCA establishment, the UE can obtain measurements before DCCA is established. In particular, these early measurements can be obtained when the UE is idle or inactive.

[0049] The UE can be configured to perform early measurements, also referred to herein as idle-mode measurements. Idle-mode measurements can refer to early measurements performed in idle and inactive states. Alternatively, as explained herein, the configuration for idle-mode measurements can also be used to record early measurements for MDT purposes. The UE can receive an idle-mode measurement configuration from a base station, and the idle-mode measurement settings can include configuration information for performing measurements when the UE is in an idle or inactive state. For example, the early measurement configuration can be received in a Radio Resource Control (RRC) release signaling from a base station or in a System Information Block (SIB) transmission. The UE can determine which MDT reports the measurements can also be used for recording based on the idle-mode measurement configuration. For example, the UE can determine which MDT reports the measurements can be used for recording based on whether location information is configured in the idle-mode measurement configuration or based on flags included in the idle-mode measurement configuration. The UE can generate multiple idle-mode measurement reports (based on different idle-mode measurement configurations and updated configurations). Alternatively, the UE can generate MDT reports (based on the recorded MDT configuration, or based on the recorded MDT configuration and the updated idle-mode measurement configuration). In this regard, the UE can be configured to generate and transmit idle mode measurement reports and MDT reports independently of each other. The UE can also send reports to the base station.

[0050] The UE may measure the Radio Access Technology (RAT) of the adjacent area or the RAT that the UE is configured to use for wireless communication. Similarly, the UE may measure adjacent frequencies or frequencies that the UE is configured to use. Measurements of the UE's adjacent RATs or RATs, and measurements of the UE's adjacent frequencies or frequencies, or combinations of these items, may be included in idle mode measurement reports (e.g., early measurement reports), recorded MDT reports, or both.

[0051] The various aspects of this disclosure are first described in the context of a wireless communication system. Then, the various aspects of this disclosure are described with respect to process flow. The various aspects of this disclosure are further illustrated by apparatus diagrams, system diagrams, and flowcharts relating to early measurements for recording MDT, and are described with reference to these diagrams.

[0052] Figure 1An example of a wireless communication system 100 supporting early measurements of a recorded MDT (Multidisciplinary Team) is shown according to various aspects of this disclosure. The wireless communication system 100 may include one or more base stations 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an improved LTE (LTE-A) network, an LTE-APro network, or a New Radio (NR) network. In some examples, the wireless communication system 100 may support enhanced broadband communication, ultra-reliable (e.g., mission-critical) communication, low-latency communication, or communication with low-cost and low-complexity devices, or any combination thereof.

[0053] Base stations 105 can be distributed throughout a geographical area to form a wireless communication system 100, and can be devices of different forms or with different capabilities. Base stations 105 and UE 115 can communicate wirelessly via one or more communication links 125. Each base station 105 can provide a coverage area 110, and UE 115 and base station 105 can establish one or more communication links 125 on the coverage area 110. Coverage area 110 can be an example of a geographical area where base station 105 and UE 115 can support signal transmission according to one or more RATs.

[0054] UE 115 can be distributed throughout the entire coverage area 110 of the wireless communication system 100, and each UE 115 can be stationary, mobile, or both at different times. UE 115 can be devices of different forms or with different capabilities. Figure 1 Some example UE 115s are shown in the document. The UE 115 described herein is capable of communicating with various types of devices, such as other UE 115s, base station 105, or network devices (e.g., core network nodes, relay devices, integrated access and backhaul (IAB) nodes, or other network devices), such as... Figure 1 As shown.

[0055] Base station 105 can communicate with core network 130, communicate with each other, or perform both of these operations. For example, base station 105 can interface with core network 130 via one or more backhaul links 120 (e.g., via S1, N2, N3, or other interfaces). Base station 105 can communicate with each other directly (e.g., directly between base stations 105) on backhaul links 120 (e.g., via X2, Xn, or other interfaces), or indirectly (e.g., via core network 130), or perform both of these operations. In some examples, backhaul link 120 can be or includes one or more radio links.

[0056] One or more of the base stations 105 described herein may include, or may be referred to by those skilled in the art as, base station transceiver, radio base station, access point, radio transceiver, node B, evolved node B (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), home node B, home evolved node B, or some other suitable term.

[0057] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or some other suitable term, wherein "device" may also be referred to as a unit, station, terminal, or client, and other examples. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, and other examples, which may be implemented in various articles such as electrical appliances, vehicles, meters, and other examples.

[0058] The UE 115 described in this document can communicate with various types of devices, such as other UE 115s that can sometimes act as repeaters, as well as base station 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, and other examples, such as... Figure 1 As shown.

[0059] UE 115 and base station 105 can wirelessly communicate with each other via one or more communication links 125 on one or more carriers. The term "carrier" can refer to a set of radio frequency spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of a radio frequency spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling coordinating operation for the carrier, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers.

[0060] In some examples (e.g., in a carrier aggregation configuration), carriers may also have acquisition or control signaling that coordinates operation against other carriers. Carriers may be associated with frequency channels (e.g., Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Channel Number (EARFCN)) and may be positioned according to a channel grid for discovery by UE 115. Carriers may operate in standalone mode, where UE 115 performs initial acquisition and connection via a carrier, or in non-standalone mode, where different carriers (e.g., of the same or different RATs) are used to anchor the connection.

[0061] The communication link 125 shown in the wireless communication system 100 may include uplink transmission from UE 115 to base station 105, or downlink transmission from base station 105 to UE 115. The carrier may carry downlink or uplink communication (e.g., in FDD mode) or may be configured to carry both downlink and uplink communication (e.g., in TDD mode).

[0062] A carrier may be associated with a specific bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the carrier or the “system bandwidth” of the wireless communication system 100. For example, the carrier bandwidth may be one of a number of defined bandwidths for a specific RAT (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Devices of the wireless communication system 100 (e.g., base station 105, UE 115, or both) may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configurable to support communication on one carrier bandwidth in a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., a subband, BWP) or all of the carrier bandwidth.

[0063] The signal waveform transmitted on a carrier can consist of multiple subcarriers (e.g., using multicarrier modulation (MCM) techniques such as Orthogonal Frequency Division Multiplexing (OFDM) or Discrete Fourier Transform Spread Spectrum OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element can include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits carried by each resource element can depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both). Therefore, the more resource elements UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for UE 115. Wireless communication resources can refer to a combination of radio frequency spectrum resources, temporal resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial layers can further increase the data rate or data integrity used for communication with UE 115.

[0064] One or more digital schemes (numerologies) can be supported for a carrier, where the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier can be divided into one or more BWPs with the same or different digital schemes. In some examples, UE 115 can be configured with multiple BWPs. In some examples, a single BWP for a carrier can be active at a given time, and communication for UE 115 can be restricted to one or more active BWPs.

[0065] It can be expressed in a basic unit of time (which can be, for example, T). s =1 / (Δf) max ·N f The sampling period is ) seconds, where Δf max This can represent the maximum supported subcarrier spacing, and N f The time interval for base station 105 or UE 115 can be represented as a multiple of the maximum supported Discrete Fourier Transform (DFT) size. The time interval for communication resources can be organized based on radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0066] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., this depends on the length of the cyclic prefix added before each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple micro-time slots containing one or more symbols. Excluding the cyclic prefix, each symbol period may contain one or more (e.g., N) f (Number) sampling periods. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0067] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst form of a shortened TTI (sTTI)).

[0068] Physical channels can be multiplexed on a carrier using various techniques. For example, one or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used to multiplex physical control channels and physical data channels on a downlink carrier. A control region (e.g., a control resource set (CORESET)) for physical control channels can be defined by the number of symbol periods and can extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) can be configured for a group of UEs 115. For example, one or more of the UEs 115 can monitor or search for control regions against control information based on one or more search space sets, and each search space set can include one or more control channel candidates arranged in a cascaded manner at one or more aggregation levels. The aggregation level for control channel candidates can refer to the number of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space set may include a common search space set configured to send control information to multiple UEs 115 and a UE-specific search space set used to send control information to a specific UE 115.

[0069] Each base station 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hotspots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used (e.g., on a carrier) to communicate with base station 105 and may be associated with an identifier used to distinguish neighboring cells (e.g., Physical Cell Identifier (PCID), Virtual Cell Identifier (VCID), or other identifier). In some examples, a cell may also refer to a geographic coverage area 110 or a portion of geographic coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors (such as the capabilities of base station 105), the range of such cells can range from small areas (e.g., structures, subsets of structures) to large areas. For example, a cell may be or include buildings, subsets of buildings, or external space between or overlapping geographic coverage areas 110, and other examples.

[0070] Macro cells typically cover a relatively large geographical area (e.g., a radius of several kilometers) and can allow unrestricted access by UE 115 with a service subscription to a network provider supporting the macro cell. In contrast, small cells can be associated with a lower-power base station 105 and can operate in the same or different (e.g., licensed, unlicensed) frequency bands as macro cells. Small cells can provide unrestricted access to UE 115 with a service subscription to a network provider, or restricted access to UE 115 associated with the small cell (e.g., UE 115 in a Closed Subscriber Group (CSG), or UE 115 associated with a user in a residence or office). Base station 105 can support one or more cells and can also support communication on one or more cells using one or more component carriers.

[0071] In some examples, a carrier can support multiple cells and can be configured with different cells based on different protocol types that can provide access for different types of devices (e.g., MTC, Narrowband IoT (NB-IoT), Enhanced Mobile Broadband (eMBB)).

[0072] In some examples, base station 105 may be mobile, and therefore provide communication coverage for mobile geographic coverage areas 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, but different geographic coverage areas 110 may be supported by the same base station 105. In other examples, overlapping geographic coverage areas 110 associated with different technologies may be supported by different base stations 105. Wireless communication system 100 may include, for example, a heterogeneous network, in which different types of base stations 105 use the same or different RATs to provide coverage for various geographic coverage areas 110.

[0073] The wireless communication system 100 can support synchronous or asynchronous operation. For synchronous operation, base stations 105 can have similar frame timings, and transmissions from different base stations 105 can be approximately time-aligned. For asynchronous operation, base stations 105 can have different frame timings, and in some examples, transmissions from different base stations 105 may not be time-aligned. The techniques described herein can be used for both synchronous and asynchronous operation.

[0074] Some UE 115s (e.g., MTC or IoT devices) can be low-cost or low-complexity devices and can provide automated machine-to-machine communication (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC can refer to data communication technologies that allow devices to communicate with each other or with base station 105 without human intervention. In some examples, M2M communication or MTC can include communication from devices that have integrated sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents it to humans interacting with the application. Some UE 115s can be designed to collect information or automate the behavior of machines or other devices. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based billing.

[0075] Some UE 115s can be configured to operate in a power-saving mode, such as half-duplex communication (e.g., a mode that supports unidirectional communication via either transmission or reception, rather than simultaneous transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power-saving techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communication, when operating on limited bandwidth (e.g., according to narrowband communication), or a combination of these techniques. For example, some UE 115s can be configured to operate using a narrowband protocol type associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs) within a carrier, within a carrier's guard band, or outside a carrier.

[0076] Wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC) or mission-critical communication. UE 115 can be designed to support ultra-reliable, low-latency, or mission-critical functions (e.g., mission-critical functions). Ultra-reliable communication can include private or group communication and can be supported by one or more mission-critical services (such as mission-critical push-to-talk (MCPTT), mission-critical video (MCVideo), or mission-critical data (MCData)). Support for mission-critical functions can include service prioritization, and mission-critical services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, mission-critical, and ultra-reliable low-latency are used interchangeably herein.

[0077] In some examples, UE 115 is able to communicate directly with other UE 115 on a device-to-device (D2D) communication link 135 (e.g., using peer-to-peer (P2P) or D2D protocols). One or more UE 115s utilizing D2D communication can be within the geographic coverage area 110 of base station 105. Other UE 115s in such a group may be outside the geographic coverage area 110 of base station 105 or otherwise unable to receive transmissions from base station 105. In some examples, groups of UE 115s communicating via D2D communication can utilize a one-to-many (1:M) system, where each UE 115 transmits to every other UE 115 in the group. In some examples, base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UE 115s without involving base station 105.

[0078] In some systems, the D2D communication link 135 may be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicle may communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. The vehicle may signal information relating to traffic conditions, signal control, weather, safety, emergencies, or any other information relating to the V2X system. In some examples, a vehicle in a V2X system may communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., base station 105) using vehicle-to-network (V2N) communication, or both.

[0079] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can be an evolved packet core (EPC) or a 5G core (5GC), and can include at least one control plane entity (e.g., a mobility management entity (MME), access and mobility management function unit (AMF)) managing access and mobility, and at least one user plane entity (e.g., a serving gateway (S-GW), packet data network (PDN) gateway (P-GW), or user plane function unit (UPF)) routing packets to or interconnecting with external networks. The control plane entity can manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for UE 115 served by base station 105 associated with core network 130. User IP packets can be transmitted through the user plane entity, which can provide IP address allocation and other functions. The user plane entity can connect to network operator IP service 150. Network operator IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0080] Some network devices (e.g., base station 105) may include sub-components such as access network entity 140, which may be an example of an access node controller (ANC). Each access network entity 140 may communicate with UE 115 through one or more other access network transport entities 145 (which may be referred to as a radio headend, smart radio headend, or transmit / receive point (TRP)). Each access network transport entity 145 may include one or more antenna panels. In some configurations, the various functions of each access network entity 140 or base station 105 may be distributed across individual network devices (e.g., radio headends and ANCs) or incorporated into a single network device (e.g., base station 105).

[0081] Wireless communication system 100 can operate using one or more frequency bands (typically in the range of 300 MHz to 300 GHz). The region from 300 MHz to 3 GHz is often referred to as the Ultra High Frequency (UHF) region or decimeter band because the wavelength range extends from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, but the waves can be sufficiently permeable to penetrate structures for use in macrocells to provide service to UE 115 located indoors. Compared to the transmission of smaller frequencies and longer waves in the lower 300 MHz portion of the spectrum in the High Frequency (HF) or Very High Frequency (VHF) regions, UHF wave transmission can be associated with smaller antennas and shorter distances (e.g., less than 100 km).

[0082] The wireless communication system 100 can also operate in the ultra-high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz (also referred to as the centimeter band) or in the extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also referred to as the millimeter band). In some examples, the wireless communication system 100 can support millimeter-wave (mmW) communication between the UE 115 and the base station 105, and the EHF antennas of the corresponding device can be even smaller and more closely spaced compared to UHF antennas. In some examples, this can facilitate the use of antenna arrays within the device. However, EHF transmissions may suffer from even greater atmospheric attenuation and shorter distances compared to SHF or UHF transmissions. The techniques disclosed herein can be employed across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary depending on the country or regulatory authority.

[0083] Wireless communication system 100 can utilize both licensed and unlicensed radio frequency spectrum bands. For example, wireless communication system 100 can employ licensed assisted access (LAA), LTE unlicensed (LTE-U) RAT, or NR technologies in unlicensed frequency bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band). When operating in unlicensed radio frequency spectrum bands, devices (such as base station 105 and UE 115) can employ carrier sensing for collision detection and avoidance. In some examples, operation in unlicensed frequency bands can be based on carrier aggregation configurations that combine component carriers operating in licensed frequency bands (e.g., LAA). Operation in unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and other examples.

[0084] Base station 105 or UE 115 may be equipped with multiple antennas, which can be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of base station 105 or UE 115 may be located within one or more antenna arrays or antenna panels (which may support MIMO operation or transmit or receive beamforming). For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, the antennas or antenna arrays associated with base station 105 may be located in different geographical locations. Base station 105 may have an antenna array having a number of rows and columns of antenna ports that base station 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may have one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, antenna panels may support radio frequency beamforming for signals transmitted via antenna ports.

[0085] Base station 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such a technique can be called spatial multiplexing. For example, a transmitting device can transmit multiple signals via different antennas or different combinations of antennas. Similarly, a receiving device can receive multiple signals via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry bits associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) (where multiple spatial layers are transmitted to the same receiving device) and multi-user MIMO (MU-MIMO) (where multiple spatial layers are transmitted to multiple devices).

[0086] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., base station 105, UE 115) to form or guide an antenna beam (e.g., transmit beam, receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating relative to a specific orientation of the antenna array experience constructive interference, while others experience destructive interference. Adjustments to the signals transmitted via the antenna elements can include applying amplitude offset, phase offset, or both to the signals carried via the antenna elements associated with the transmitting or receiving device. The adjustments associated with each antenna element can be defined by a set of beamforming weights associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device, or relative to some other orientation).

[0087] As part of beamforming operations, base station 105 or UE 115 may use beam scanning techniques. For example, base station 105 may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Base station 105 may transmit some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) multiple times in different directions. For example, base station 105 may transmit signals according to different sets of beamforming weights associated with different transmission directions. Transmissions in different beam directions may be used (e.g., by a transmitting device (such as base station 105) or by a receiving device (such as UE 115)) to identify the beam direction for subsequent transmissions or receptions performed by base station 105.

[0088] Base station 105 may transmit signals (e.g., data signals associated with a specific receiving device, such as UE 115) in a single beam direction (e.g., a direction associated with a particular receiving device, such as UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on signals transmitted in one or more beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions and may report to base station 105 an indication of the signal received by UE 115 that has the highest signal quality or otherwise acceptable signal quality.

[0089] In some examples, multiple beam directions can be used to perform transmissions by a device (e.g., base station 105 or UE 115), and the device can use a combination of digital precoding or radio frequency beamforming to generate combined beams for (e.g., from base station 105 to UE 115) transmissions. UE 115 can report feedback indicating precoding weights for one or more beam directions, and this feedback can correspond to a configured number of beams spanning the system bandwidth or one or more subbands. Base station 105 can transmit reference signals that can be precoded or unprecoded (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)). UE 115 can provide feedback on beam selection, which can be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., multi-panel type codebook, linear combination type codebook, port selection type codebook). Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may employ similar techniques to transmit signals multiple times in different directions (e.g., to identify beam directions for subsequent transmissions or receptions by UE 115) or to transmit signals in a single direction (e.g., to transmit data to a receiving device).

[0090] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, the receiving device (e.g., UE 115) can attempt multiple receiving configurations (e.g., directional listening). For example, the receiving device can attempt multiple receiving directions by receiving via different antenna subarrays, by processing the received signals according to different antenna subarrays, by receiving according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (e.g., different sets of directional listening weights), or by processing the received signals according to different sets of receiving beamforming weights applied to signals received at multiple antenna elements of the antenna array (any of these operations can be referred to as "listening" according to different receiving configurations or receiving directions). In some examples, the receiving device can use a single receiving configuration to receive along a single beam direction (e.g., when receiving data signals). A single receiver configuration can be aligned to a beam direction determined based on listening in different receiver configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or otherwise acceptable signal quality based on listening in multiple beam directions).

[0091] The wireless communication system 100 can be a packet-based network operating according to a layered protocol stack. In the user plane, communication at the bearer or Packet Data Convergence Protocol (PDCP) layer can be IP-based. The Radio Link Control (RLC) layer can perform packet fragmentation and reassembly for transmission over logical channels. The Media Access Control (MAC) layer can perform priority handling and multiplexing of logical channels to transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. In the control plane, the RRC protocol layer can provide the establishment, configuration, and maintenance of RRC connections (which support radio bearers for user plane data) between the UE 115 and the base station 105 or core network 130. At the physical layer, transport channels can be mapped to physical channels.

[0092] UE 115 and base station 105 can support data retransmission to increase the likelihood of successful data reception. Hybrid Automatic Repeat Request (HARQ) feedback is a technique used to increase the likelihood of correct data reception on communication link 125. HARQ can include a combination of error detection (e.g., using Cyclic Redundancy Check (CRC)), forward error correction (FEC), and retransmission (e.g., Automatic Repeat Request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal and noise conditions). In some examples, the device can support same-slot HARQ feedback, where the device can provide HARQ feedback for data received in a previous symbol within a specific time slot. In other cases, the device can provide HARQ feedback in subsequent time slots or according to some other time interval.

[0093] UE 115 can perform network measurements when it is in an idle or inactive state. UE 115 can receive from base station 105 an idle mode measurement configuration and a recorded measurement configuration for performing measurements when UE 115 is in an idle or inactive state. UE 115 can determine, based on the idle mode measurement configuration, that the measurements will also be used for MDT reporting. UE 115 can generate one or more idle mode measurement reports, MDT reports, or both based on the idle mode measurement configuration and the recorded measurement configuration. UE 115 can send one or more idle mode measurement reports, MDT reports, or both to base station 105 based on the idle mode measurement configuration and the recorded measurement configuration.

[0094] Figure 2An example of a wireless communication system 200 supporting early measurements for recorded MDTs according to various aspects of this disclosure is shown. In some examples, the wireless communication system 200 may implement aspects of the wireless communication system 100. The wireless communication system 200 may include a UE 115-a and a base station 105-a, which may be respectively referenced to Figure 1 Examples of UE 115 and base station 105 described.

[0095] Base station 105-a can communicate with UE 115-a and can transmit signals on downlink channel 205-a. UE 115-a can communicate with base station 105-a by transmitting signals on uplink channel 205-b. UE 115-a can perform or be used for early measurements in MDT reporting (such as recorded MDT reports). For example, based on the capabilities of UE 115-a, early measurements can be captured by UE 115-a and used for MDT purposes. Therefore, recorded MDT measurements can be enhanced.

[0096] Base station 105-a can send an indication of idle mode measurement configuration 210 to UE 115-a. UE 115-a can determine whether idle mode measurement configuration 210 can also be used for MDT reporting. In some cases, base station 105-a can send idle mode measurement configuration 210 with location information. The location information can indicate that UE 115-a can also use idle mode measurement configuration 210 to perform recorded MDT reporting. In other cases, base station 105-a can include a flag (e.g., earlyMeasForLoggedMDT flag) in idle mode measurement configuration 210 indicating whether UE 115-a can also use idle mode measurement configuration 210 for MDT recording purposes and reporting.

[0097] The idle mode measurement configuration 210 may include an indication or carrier list (such as NR carriers or E-UTRA carriers) and a valid area for performing measurements. In some cases, base station 105-a may send the idle mode measurement configuration 210 in an RRC release signaling message. In these cases, UE 115-a may use the idle mode measurement configuration 210 received in the RRC release signaling message. After receiving the RRC release message, UE 115-a may perform idle mode measurements according to the idle mode measurement configuration 210 while in an idle or inactive state. In other cases, UE 115-a may receive the idle mode measurement configuration 210 from base station 105-a in an SIB transmission (e.g., in SIB11 or SIB16). If UE 115-a receives both an RRC release message and an SIB transmission with this configuration, UE 115-a may use the configuration received in the RRC release message and may ignore the configuration received in the SIB transmission. The additional idle mode measurement configuration 210 can be updated by receiving the idle mode measurement configuration 210 in a subsequent SIB transmission.

[0098] In the case of an MDT report recorded using the Idle Mode Measurement Configuration 210, UE 115-a may additionally or alternatively generate an earlier measurement report for the recorded MDT report. This earlier measurement report may include the Idle Mode Measurement Report 215. UE 115-a may include a timestamp or cell identifier in the Idle Mode Measurement Report 215, which base station 105-a may use to determine whether UE 115-a used the Idle Mode Measurement Report 215 for DCCA enhancement. UE 115-a may include location information in the Idle Mode Measurement Report 215. Location information may include Global Navigation Satellite System (GNSS), Wireless Local Area Network (WLAN), Bluetooth, and sensor location information. Configurations for each of these parameters may be included in the Idle Mode Measurement Configuration 210. If base station 105-a identifies that UE 115-a used the Idle Mode Measurement Report 215 for DCCA, base station 105-a may ignore the location information in the report. Base station 105-a can report idle mode measurement report 215 to the tracking collection entity (TCE) and can indicate that the report was obtained by UE 115-a using idle mode measurement configuration.

[0099] Furthermore, UE 115-a can use the most recently received idle mode measurement configuration 210 to report idle mode measurement report 215, and can indicate to base station 105-a that more idle mode measurement reports 215 are available. In some cases, base station 105-a can indicate the intention to receive multiple idle mode measurement reports 215 simultaneously, and can request more idle mode measurement reports 215 from UE 115-a by sending an information request to UE 115-a (e.g., by sending a UEInformationRequest message).

[0100] If a previous idle mode measurement configuration 210 is overwritten by a new configuration, UE 115-a can store multiple different idle mode measurements (e.g., for idle mode measurement report 215). For example, base station 105-a can send an SIB with an updated idle mode measurement configuration 210. UE 115-a can store previous reports with timestamps or cell identifiers or both, and can send reports to base station 105a upon request from base station 105-a.

[0101] In some cases, base station 105-a may send MDT configuration 215 to UE 115-a. MDT configuration 215 may be an example of a recorded measurement configuration (e.g., logged Measurement Configuration). MDT configuration 215 may also be referred to as a recorded MDT configuration. MDT configuration 215 may indicate to UE 115-a whether idle mode measurement configuration 210 can also be used by UE 115-a for MDT reporting. Furthermore, MDT configuration 215 may include frequency and cell information that UE 115-a can use to perform idle mode measurements.

[0102] For example, before UE 115-a receives the RRC release message, UE 115-a can use Idle Mode Measurement Configuration 210 to generate and report an Idle Mode Measurement Report, including measurements of adjacent RATs and frequencies. UE 115-a can also obtain a list of adjacent RATs and frequencies from MDT Report 220. UE 115-a can obtain the list of adjacent RATs and frequencies based solely on MDT Configuration 215 (e.g., the recorded measurement configuration) or based on both MDT Configuration 215 and Idle Mode Measurement Configuration 210. Once UE 115-a receives MDT Configuration 215, UE 115-a can collect RAT and frequency measurements according to MDT Configuration 215, which may include RATs and frequencies for MDT reporting, and may differ from the RATs or frequencies included in Idle Mode Measurement Configuration 210. This is when UE 115-a is in an idle or inactive state (e.g., after receiving the RRC release message). If the recorded MDT timer is running, UE 115-a can discard the previous measurement configuration (e.g., from the original idle mode measurement configuration).

[0103] In some cases, while the recorded MDT timer is running, UE 115-a can use Idle Mode Measurement Configuration 210 to report Radio Resource Measurements (RRMs) on adjacent RATs and frequencies. UE 115-a can then receive MDT Configuration 215 and use it to obtain a list of adjacent RATs and frequencies for generating and sending MDT Report 220. Once UE 115-a receives an updated Idle Mode Measurement Configuration, it can avoid measuring adjacent RATs and frequencies, which may have already been configured in the previous Idle Mode Measurement Configuration 210. UE 115-a can override Idle Mode Measurement Configuration 210 (e.g., by utilizing an updated Idle Mode Measurement Configuration 210 received in the SIB) and can add measurements of UE 115-a's RATs and frequencies for reporting via MDT Report 220.

[0104] In some cases, UE 115-a may be unable to receive the MDT configuration, and in these cases, the Idle Mode Measurement Configuration 210 may not be considered for MDT reporting purposes. In some cases, UE 115-a can obtain MDT measurements by combining adjacent RAT measurements and adjacent frequency measurements. In these cases, UE 115-a can create and generate a single report that combines information from the Idle Mode Measurement Report 215 and the MDT Report 220. UE 115-a can send the combined report to base station 105-a. As previously mentioned herein, UE 115-a can be configured to generate and send the Idle Mode Measurement Report 215 and the MDT Report 220 separately and / or independently of each other.

[0105] Figure 3 An example of a process flow 300 supporting early measurements for a recorded MDT according to various aspects of this disclosure is shown. In some examples, process flow 300 may implement various aspects of wireless communication systems 100 and 200. Process flow 300 includes UE 115-b, which may be as referenced Figure 1 and Figure 2 An example of UE 115 is described. Process flow 300 also includes base station 105-b, which can be as described in reference. Figure 1 and 2 An example of base station 105 is described. UE 115-a and base station 105-b can communicate on downlink and uplink channels.

[0106] At 305, base station 105-b can identify the idle mode measurement configuration used by UE 115-b to perform measurements in the idle or inactive state of UE 115-b. In some cases, base station 105-b can receive instructions on the MDT report configuration from the Operation, Administration and Maintenance (OAM) network equipment. OAM can send the MDT report configuration to the base station through the Access and Mobility Function Unit (AMF).

[0107] At 310, UE 115-b can receive from base station 105-b an idle mode measurement configuration for performing measurements when UE 115-b is in an idle or inactive state. UE 115-b can receive the idle mode measurement configuration as part of an SIB transmission from base station 105-b. UE 115-b can also receive the idle mode measurement configuration as part of an RRC release message sent from base station 105-b. In some cases, UE 115-b can receive both the SIB transmission from base station 105-b and the RRC release message sent from base station 105-b, where both the SIB and RRC release messages include the corresponding idle mode measurement configuration.

[0108] At 320, UE 115-b can determine from the idle mode measurement configuration that the measurement will also be used for MDT reporting. In some cases, UE 115-b can recognize that the idle mode measurement configuration received at 310 includes location information. In these cases, UE 115-b can determine that the idle mode measurement configuration will also be used for MDT reporting (e.g., recorded MDT reports) based on the location information included in the idle mode measurement configuration. In other cases, UE 115-b can recognize that the idle mode measurement configuration includes a flag that indicates that the idle mode measurement configuration will also be used for MDT reporting.

[0109] When UE 115-b receives the idle mode configuration in both the SIB transmission and the RRC release message from base station 105-b, UE 115-b can identify the idle mode measurement configuration from the RRC release information. For example, UE 115-b can ignore the idle mode measurement configuration from the SIB transmission.

[0110] UE 115-b can also receive recorded measurement configurations, which can instruct UE 115-b to use idle mode measurement configurations to obtain measurements for MDT reporting and for the generation of MDT reports.

[0111] UE 115-b can receive a recorded measurement configuration, which includes at least one of frequency or cell information included in the idle mode measurement configuration, wherein the measurement can be based on the recorded measurement configuration and the idle mode measurement configuration and the recorded measurement configuration.

[0112] At 325, UE 115-b can generate one or more idle mode measurement reports, MDT reports, or both based on the idle mode measurement configuration. For example, in some cases, UE 115-b can generate a recorded MDT report based on the idle mode measurement configuration and the recorded MDT configuration, and can report only the most recent measurement based on the idle mode measurement configuration in the idle mode measurement report. In other cases, UE 115-b can generate one or more idle mode measurement reports based on the recorded idle mode configuration, and generate an MDT report based on the idle mode measurement and the recorded MDT configuration.

[0113] UE 115-b can identify one or more adjacent RATs, one or more adjacent frequencies, or a combination of these based on the recorded MDT configuration and idle mode measurement configuration. For example, UE 115-b can obtain a list of adjacent RATs, adjacent frequencies, or both based on the recorded MDT configuration and idle mode measurement configuration. UE 115-b can measure one or more adjacent RATs, one or more adjacent frequencies, or a combination of these. UE 115-b can also measure UE 115-b's RAT, and UE 115-b's frequency, or both.

[0114] In some cases, UE 115-b can recognize that the MDT timer is running. In these cases, UE 115-b can recognize one or more adjacent RATs, adjacent frequencies, or a combination of these. UE 115-b can generate an MDT report at 325 based on measurements to be used for the MDT report according to the idle mode measurement configuration, wherein the MDT report includes measurements of one or more adjacent RATs, one or more adjacent frequencies, or a combination of these.

[0115] At 330, UE 115-b can receive SIB transmissions from base station 105-b, which include updated idle mode measurement configurations. UE 115-b can override the idle mode configuration (received at 310) based on the updated idle mode measurement configurations.

[0116] At 335, upon receiving an updated idle mode measurement configuration, UE 115-b may avoid recording measurements of one or more adjacent RATs, one or more adjacent frequencies, or combinations in the recorded MDT report based on the identification that the MDT timer is not running, wherein the one or more adjacent RATs, one or more adjacent frequencies, or combinations are based on the idle mode measurement configuration. If the T330 timer is not running, UE 115-b may be configured to record measurements only in the idle mode measurement report. Otherwise, at 335, after receiving an updated idle mode measurement configuration, UE 115-b may initiate measurements of different sets of one or more adjacent RATs, one or more adjacent frequencies, or combinations based on the updated idle mode measurement configuration. The set of one or more adjacent RATs and one or more adjacent frequencies may be based on the updated idle mode measurement configuration.

[0117] In an additional or alternative aspect, if timer T330 is running, UE 115-b can be configured to update the recorded configuration by restarting the idle mode measurement configuration. This can be compared to the behavior of UE 115-b described above when timer T330 is not running.

[0118] At location 340, UE 115-b may send one or more idle mode measurement reports. These idle mode measurement reports may include location information. In some cases, UE 115-b may send a newly generated idle mode measurement report based on one or more idle mode measurement reports sent at location 340. UE 115-b may send an indication to base station 105-b that one or more additional idle mode measurement reports may be available for transmission to base station 105-a.

[0119] In some cases, UE 115-b may receive an indication from base station 105-b that UE 115-b will send multiple idle mode measurement reports to base station 105-b. UE 115-b may then send at least a set of one or more idle mode measurement reports to base station 105-b based on the receipt of the indication. Each idle mode measurement report in the set of one or more idle mode measurement reports may be associated with a timestamp or cell identifier.

[0120] Base station 105-b can recognize that UE 115-b has sent one or more idle mode measurement reports to perform DCCA. In these cases, base station 105-b can ignore the location information included in the idle mode measurement report.

[0121] Furthermore, at 345, when the idle mode measurement timer T331 expires, UE 115-b can avoid measuring one or more adjacent RATs, one or more adjacent frequencies, or combinations thereof based on the updated idle mode configuration received at 330. Based on the determination that the MDT timer is still running, UE 115-b can maintain measurements of UE 115-b's RAT, UE 115-b's frequency, or both, in the recorded MDT report. Furthermore, updating the measurement records of different RATs, or frequencies, or both of UE 115-b in the recorded MDT report can be based on the determination that the MDT timer is running and on receiving an SIB including the updated idle mode measurement configuration. Additionally, in some aspects, if timer T330 is running and timer T331 expires, UE 115-b can be configured to update the recorded MDT configuration by removing the idle mode measurement configuration.

[0122] At 350, UE 115-b can receive requests for MDT reports. At 355, UE 115-b can send MDT reports based on idle mode measurement configuration. MDT reports may include measurements of UE 115-b's RAT, UE 115-b's frequency, or both. MDT reports may also include measurements of one or more adjacent RATs, one or more adjacent frequencies, or a combination of these, and may or may not include measurements of UE 115-b's RAT or UE 115-b's frequency.

[0123] Base station 105-b can send one or more idle mode measurement reports to the Tracking Collection Entity (TCE), wherein the one or more idle mode measurement reports will be used for MDT reporting. Base station 105-b can also send MDT reports to the TCE. Base station 105-b can indicate to the TCE that one or more idle mode measurement reports were collected together with or associated with the idle mode measurement configuration.
