[0002] This patent application claims priority to U.S. Patent Application No. 16 / 503,980 of Lee et al., entitled “ADAPTIVE MONITORING,” filed on July 5, 2019, and U.S. Provisional Patent Application No. 62 / 696,273 of Lee et al., entitled “ADAPTIVE MONITORING,” filed on July 10, 2018, which are assigned to their assignees and are incorporated herein by reference in their entirety. Background Art

[0003] The following relates generally to wireless communications, and more particularly to adaptive monitoring.

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems can be capable of supporting communication for multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of these multiple access systems include fourth generation (4G) systems, such as long term evolution (LTE) systems, advanced 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 may employ techniques 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 spread spectrum OFDM (DFT-S-OFDM). A wireless multiple access communication system may include multiple base stations or network access nodes, each of which simultaneously supports communication for multiple communication devices, which may otherwise be known as user equipment (UE).

[0005] Wireless communication systems may operate in the millimeter wave (mmW) frequency range (e.g., 28 GHz, 40 GHz, 60 GHz, etc.). Wireless communication at these frequencies may be associated with increased signal attenuation (e.g., path loss), which may be affected by various factors, such as temperature, atmospheric pressure, diffraction, etc. As a result, signal processing techniques (such as beamforming) may be used to coherently combine energy and overcome path losses at these frequencies. Due to the increased amount of path loss in mmW communication systems, transmissions from base stations and / or UEs may be beamformed. In addition, a receiving device may use beamforming techniques to configure an antenna and / or antenna array so that the transmission is received in a directional manner.

[0006] Channel measurement and reporting techniques can be used within a wireless communication system to identify possible communication beams within a serving cell or a neighboring cell. For example, a base station and / or a UE can measure channel performance metrics for one or more transmit beams and send a feedback message reporting the measurement results. In some cases, in order to obtain a measurement report, the base station and / or the UE may have to perform complex and time-dependent steps. For example, each beam measurement may include different operations for measuring different types of reference signals, which may change based on the type of beam measurement performed. Further, based on the mobility of the device performing the measurement, the monitored active communication beams may change more frequently, and the measurements may not have a clearly defined time frame established for the measurement report. In this way, conventional techniques may result in excessive signaling, unnecessary measurements, scheduling restrictions, unnecessary power consumption and / or time delays, and ambiguous time frames for obtaining measurement reports. Summary of the invention

[0007] The described technology relates to improved methods, systems, devices and apparatuses for supporting adaptive monitoring. In general, the described technology provides dynamic modification of reference signal (RS) measurement configurations, which can be continuously adapted based on the conditions of the UE (e.g., the mobility of the UE, the channel quality experienced at the UE, the discontinuous reception (DRX) mode, etc.). RS measurements based on measurement configurations can be used for intra-cell or inter-cell channel quality measurements, and RS measurements can be used for different types of measurements, such as beam management (BM), radio resource management (RRM), radio link monitoring (RLM) and channel tracking. In some cases, multiple measurement configurations can be provided to the UE. In these cases, each measurement configuration can include different measurement parameter sets (e.g., measurement periodicity, offset, window size, etc.) for RS of a measurement cell (e.g., a serving cell, a neighboring cell, etc.). Therefore, a UE configured with multiple measurement configurations can activate, deactivate and / or switch between different measurement configurations implicitly or based on explicit signaling from a base station. For example, a base station may dynamically instruct (e.g., using downlink control information (DCI), medium access control (MAC) control elements (CE), etc.) a UE to activate, deactivate, or switch to a selected measurement configuration of a plurality of measurement configurations. In some examples, explicit signaling of the selected measurement configuration may be based on a subsampling rule for a particular measurement configuration, wherein the periodicity and / or measurement timing may be adjusted based on the subsampling results and the channel conditions at the UE (e.g., when operating under high mobility or poor beam quality conditions). Additionally or alternatively, the measurement configuration may be implicitly adapted or adjusted based on the DRX periodicity, wherein, when the UE is in DRX mode, for example, a lower frequency of measurement or monitoring timing may be utilized. In any event, using a dynamic measurement configuration adapted to the conditions of the UE or the measurement requirements of the cell may provide a clear timeline for measurements, reduce communication delays (e.g., while avoiding scheduling restrictions), avoid excessive signaling, prevent unnecessary measurements, and the like.

[0057] The described devices and techniques provide efficient modification of RS measurement configurations, which can be based on conditions of the UE (e.g., mobility, discontinuous reception mode (DRX), beam conditions, etc.). Adaptive monitoring for RS measurement configurations can be used to minimize scheduling constraints within the network and can reduce unnecessary power consumption at the UE. RS measurement configurations can be used for BM, RRM, RLM, and channel tracking.

[0058] Typically, a UE may communicate using beamforming techniques and may perform RS measurements on beams used for communication, for example, to ensure sufficient channel quality for future communications. As described herein, multiple measurement configurations may be provided to a UE from a base station. In some cases, each measurement configuration may include different sets of measurement parameters (e.g., measurement periodicity, measurement window, etc.) for measuring RSs of one or more beams in a cell. Thus, a UE configured with one or more measurement configurations may be able to implicitly activate, deactivate different measurement configurations and / or switch between different measurement configurations based on changes in UE conditions or based on signaling from a base station. For example, a base station may send explicit signaling instructing the UE to activate / deactivate a selected measurement configuration. In other examples, the base station may indicate that the UE will switch between different measurement configurations to accommodate, for example, changes in the mobility of the UE or the channel quality experienced by the UE. In some cases, a subsampling period may be used for one or more measurement configurations, such as when additional measurements are required (e.g., when operating under high mobility and / or poor beam quality conditions). These sub-sampling periods may inform the network how a particular measurement configuration may be adjusted, and signaling from the base station may further indicate how the UE is to adjust the configured measurement parameters based on the sub-sampling results.

[0059] Changes (e.g., activation, deactivation, and / or switching) to previously used measurement configurations may be performed on a defined timeline to reduce delays, excessive signaling, unnecessary measurements, and the like. Further, the use of adaptive monitoring and / or multiple measurement configurations may reduce or eliminate scheduling constraints (e.g., due to conflicts between when the UE will perform measurements and when communications are scheduled, or due to what type of RS will be monitored). Thus, adaptive monitoring may be used by the network to dynamically increase or decrease measurement periodicity for different conditions (e.g., beam quality and / or UE mobility). For example, in a system with high beam quality and / or low UE mobility, the measurement frequency may be reduced, or inter-cell frequency measurements may be partially or completely deactivated. In some cases, the network may also use adaptive monitoring to modify the beam set for monitoring via switching to a different configuration. As a result, instead of using a static or slowly changing measurement configuration, the base station and UE may dynamically adjust the measurement configuration to perform the required measurements, thereby improving efficiency in the wireless communication system and saving power at the UE.

[0060] Aspects of the present disclosure are initially described in the context of a wireless communication system. Example operational timelines of a system using adaptive monitoring techniques are described herein. Aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to adaptive monitoring.

[0061] Figure 1 An example of a wireless communication system 100 supporting adaptive monitoring according to aspects of the present disclosure is shown. The wireless communication system 100 includes a base station 105, a UE 115, and a core network 130. In some examples, the wireless communication system 100 can be an LTE network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, or a New Radio (NR) network. In some cases, the wireless communication system 100 can support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low-latency communications, or communications with low-cost and low-complexity devices. The wireless communication system 100 can support dynamic adaptation of measurement configurations at the UE 115 through explicit or implicit selection of different measurement configurations and / or measurement parameters.

[0062] The base station 105 may communicate wirelessly with the UE 115 via one or more base station antennas. The base station 105 described herein may include or may be referred to by those skilled in the art as a base station transceiver, a radio base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB), a next generation NodeB or a giga-nodeB (all of which may be referred to as a gNB), a home NodeB, a home eNodeB, or some other suitable terminology. The wireless communication system 100 may include different types of base stations 105 (e.g., macro cell base stations or small cell base stations). The UE 115 described herein may be able to communicate with various types of base stations 105 and network devices, including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.

[0063] Each base station 105 may be associated with a particular geographic coverage area 110 in which communications with various UEs 115 are supported. Each base station 105 may provide communications coverage for a respective geographic coverage area 110 via a communications link 125, and the communications link 125 between the base station 105 and the UE 115 may utilize one or more carriers. The communications link 125 shown in the wireless communication system 100 may include an uplink transmission from the UE 115 to the base station 105, or a downlink transmission from the base station 105 to the UE 115. Downlink transmissions may also be referred to as forward link transmissions, and uplink transmissions may also be referred to as reverse link transmissions.

[0064] The geographic coverage area 110 of the base station 105 can be divided into sectors that constitute only a portion of the geographic coverage area 110, and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for a macro cell, a small cell, a hotspot, or other types of cells, or various combinations thereof. In some examples, the base station 105 can be mobile and thus provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies can overlap, and overlapping geographic coverage areas 110 associated with different technologies can be supported by the same base station 105 or different base stations 105. The wireless communication system 100 may, for example, include a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, in which different types of base stations 105 provide coverage for each geographic coverage area 110.

[0065] The term "cell" refers to a logical communication entity used to communicate with a base station 105 (e.g., via a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID)) used to distinguish between adjacent cells operating via the same carrier or different carriers. In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types that may provide access to different types of devices (e.g., machine type communication (MTC), narrowband Internet of Things (NB-IoT), enhanced mobile broadband (eMBB), etc.). In some cases, the term "cell" may refer to a portion (e.g., a sector) of a geographic coverage area 110 on which the logical entity operates.

[0066] UE 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be fixed or mobile. UE 115 can also be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where "device" can also be referred to as a unit, a station, a terminal, or a client. UE 115 can also be a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 can also refer to a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or an MTC device, etc., which can be implemented in various items such as electrical appliances, vehicles, meters, etc.

[0067] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automatic communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a base station 105 without human intervention. In some examples, M2M communication or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay the information to a central server or application, which may utilize the information or present the information to a human interacting with the program or application. Some UEs 115 may be designed to collect information or implement automatic behavior of machines. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, weather and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0068] Some UEs 115 may be configured to employ operating modes that reduce power consumption, such as half-duplex communication (e.g., a mode that supports one-way communication via transmission or reception but not 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 communications or when operating over limited bandwidth (e.g., according to narrowband communications). In some cases, UE 115 may be designed to support critical functions (e.g., mission critical functions), and the wireless communication system 100 may be configured to provide ultra-reliable communications for these functions.

[0069] In some cases, UE 115 may also be able to communicate directly with other UE 115 (e.g., using a peer-to-peer (P2P) or device-to-device (D2D) protocol). One or more of the group of UEs 115 utilizing D2D communication may be within the geographic coverage area 110 of the base station 105. Other UEs 115 in this group may be outside the geographic coverage area 110 of the base station 105, or may not otherwise be able to receive transmissions from the base station 105. In some cases, the group of UEs 115 communicating via D2D communication may utilize a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some cases, the base station 105 facilitates the scheduling of resources for D2D communication. In other cases, D2D communication is performed between UEs 115 without the involvement of the base station 105.

[0070] The base stations 105 may communicate with the core network 130 and with each other. For example, the base stations 105 may interface with the core network 130 via a backhaul link 132 (e.g., via S1, N2, N3, or other interface). The base stations 105 may communicate with each other via a backhaul link 134 (e.g., via X2, Xn, or other interface), either directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130).

[0071] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one serving gateway (S-GW), and at least one packet data network (PDN) gateway (P-GW). The MME may manage non-access layer (e.g., control plane) functions such as mobility, authentication, and bearer management for UE 115 served by a base station 105 associated with the EPC. User IP packets may be transmitted via the S-GW, which itself may be connected to the P-GW. The P-GW may provide IP address allocation and other functions. The P-GW may be connected to a network operator IP service. Operator IP services may include access to the Internet, an intranet, an IP multimedia subsystem (IMS), or a packet switched (PS) streaming service.

[0072] At least some of the network devices, such as the base station 105, may include subcomponents, such as access network entities, which may be examples of access node controllers (ANCs). Each access network entity may communicate with the UE 115 through a plurality of other access network sending entities, which may be referred to as radio heads, smart radio heads, or transmit / receive points (TRPs). In some configurations, the various functions of each access network entity or base station 105 may be distributed across various network devices (e.g., radio heads and access network controllers), or combined into a single network device (e.g., base station 105).

[0073] The wireless communication system 100 can operate using one or more frequency bands typically in the range of 300 MHz to 300 GHz. Typically, the region of 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band, because wavelengths range from about one decimeter to one meter long. Buildings and environmental features may block or redirect UHF waves. However, the waves can penetrate structures sufficiently to allow macro cells to provide services to UEs 115 located indoors. Transmission of UHF waves can be associated with smaller antennas and shorter distances (e.g., less than 100 km) compared to transmission using smaller frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0074] The wireless communication system 100 may also operate in the very high frequency (SHF) region using a frequency band of 3 GHz to 30 GHz, also known as a centimeter frequency band. The SHF region includes frequency bands such as the 5 GHz Industrial, Scientific, and Medical (ISM) band, which may be opportunistically used by devices that can tolerate interference from other users.

[0075] The wireless communication system 100 may also operate in the extremely high frequency (EHF) region (also referred to as the millimeter band) of the spectrum (e.g., 30 GHz to 300 GHz). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between the UE 115 and the base station 105, and the EHF antennas of each device may be even smaller and more closely spaced than the UHF antennas. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may suffer even greater atmospheric attenuation and shorter distances than SHF or UHF transmissions. The techniques disclosed herein may be employed between transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary from country to country or regulatory agency.

[0076] In some cases, the wireless communication system 100 can utilize licensed radio spectrum bands and unlicensed radio spectrum bands. For example, the wireless communication system 100 can use license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in unlicensed bands such as the 5GHz ISM band. When operating in an unlicensed radio spectrum band, wireless devices such as base stations 105 and UE115 can use a listen-before-talk (LBT) process to ensure that the channel is clear before sending data. In some cases, operations in unlicensed bands can be based on CA configurations and CCs operating in licensed bands (e.g., LAA). Operations in unlicensed spectrum can include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum can be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of both.

[0077] In some examples, the base station 105 or the UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., a base station 105) and a receiving device (e.g., a UE 115), wherein the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communications may employ multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers, which may be referred to as spatial multiplexing. Multiple signals may be transmitted, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry bits associated with the same data stream (e.g., the same codeword) or different data streams. Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technology includes Single-User MIMO (SU-MIMO) in which multiple spatial layers are transmitted to the same receiving device, and Multi-User MIMO (MU-MIMO) in which multiple spatial layers are transmitted to multiple devices.

[0078] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape and steer an antenna beam (e.g., a transmit beam or a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array so that signals experience constructive interference at a particular orientation relative to the antenna array, while other signals experience destructive interference. Adjustments to signals transmitted via antenna elements can include the transmitting device or the receiving device applying a certain amplitude and phase offset to the signal carried via each of the antenna elements associated with the device. The adjustments associated with each of the antenna elements can be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device, or relative to some other orientation).

[0079] In one example, the base station 105 may use multiple antennas or antenna arrays to perform beamforming operations for directional communication with the UE 115. For example, some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the base station 105 in different directions, which may include signals sent according to different beamforming weight sets associated with different transmission directions. Transmissions in different beam directions may be used to identify (e.g., by the base station 105 or a receiving device such as the UE 115) the beam direction for subsequent transmission and / or reception by the base station 105. Some signals, such as data signals associated with a particular receiving device, may be sent by the base station 105 in a single beam direction (e.g., a direction associated with a receiving device such as the UE 115). In some examples, the beam direction associated with transmissions along a single beam direction may be determined based at least in part on signals sent in different beam directions. For example, the UE 115 may receive one or more of the signals sent by the base station 105 in different directions, and the UE 115 may report an indication of the signals it received to the base station 105 with the highest signal quality or otherwise acceptable signal quality. Although these techniques are described with reference to signals sent by base station 105 in one or more directions, UE 115 may employ similar techniques for sending signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or for sending signals in a single direction (e.g., for sending data to a receiving device).

[0080] When receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105, a receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may try multiple receive beams. For example, the receiving device may try multiple receive directions by: receiving via different antenna subarrays; by processing the received signal according to different antenna subarrays; by receiving according to different receive beamforming weight sets applied to the signal received at multiple antenna elements of the antenna array; or by processing the received signal according to different receive beamforming weight sets applied to the signal received at multiple antenna elements of the antenna array, any of which may be referred to as "listening" according to different receive beams or receive directions. In some examples, the receiving device may use a single receive beam to receive along a single beam direction (e.g., when receiving a data signal). A single receive beam can be aligned in a beam direction determined based at least in part on monitoring of different receive beam directions (e.g., a beam direction determined to have the highest signal strength, the highest signal-to-noise ratio, or otherwise acceptable signal quality based at least in part on monitoring of multiple beam directions).

[0081] In some cases, the antennas of a base station 105 or a UE 115 may be located within one or more antenna arrays that may support MIMO operations, or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna component, such as an antenna tower. In some cases, the antennas or antenna arrays associated with a base station 105 may be located at different geographic locations. A base station 105 may have an antenna array with multiple rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Similarly, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

[0082] In some cases, the wireless communication system 100 can be a packet-based network that operates according to a layered protocol stack. In the user plane, the communication at the bearer or packet data convergence protocol (PDCP) layer can be based on IP. In some cases, the radio link control (RLC) layer can perform data packet segmentation and reorganization to communicate via logical channels. The medium access control (MAC) layer can perform priority processing and multiplex logical channels into transport channels. The MAC layer can also use hybrid automatic repeat request (HARQ) to provide retransmission 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 between UE 115 and the base station 105 or core network 130 that supports radio bearers for user plane data. At the physical (PHY) layer, transport channels can be mapped to physical channels.

[0083] In some cases, UE 115 and base station 105 can support retransmission of data to increase the possibility of successfully receiving data. HARQ feedback is a technique that increases the possibility of correctly receiving data via 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 the throughput at the MAC layer under poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device can support HARQ feedback for the same time slot, where the device can provide HARQ feedback for data received in the previous symbol in the time slot in a specific time slot. In other cases, the device can provide HARQ feedback in a subsequent time slot or according to some other time intervals.

[0084] Time intervals in LTE or NR can be expressed in multiples of a basic time unit, which may refer to, for example, a sampling period T s=1 / 30,720,000 seconds. The time intervals of the communication resources may be organized according to radio frames each having a duration of 10 milliseconds (ms), where the frame period may be denoted as T f =307,200T s . A radio frame can be identified by a system frame number (SFN) in the range of 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and the duration of each subframe is 1 ms. The subframe can be further divided into 2 time slots, each with a duration of 0.5 ms, and each time slot can contain 6 or 7 modulation symbol periods (e.g., depending on the length of the cyclic prefix preceding each symbol period). In addition to the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases, a subframe can be the minimum scheduling unit of the wireless communication system 100 and can be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 can be shorter than a subframe or can be dynamically selected (e.g., in a burst of a shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0085] In some wireless communication systems, a time slot may be further divided into multiple mini-slots containing one or more symbols. In some cases, a symbol of a mini-slot or a mini-slot may be the minimum unit of scheduling. For example, the duration of each symbol may vary, depending on, for example, the subcarrier spacing or the frequency band of operation. Further, some wireless communication systems may implement time slot aggregation, where multiple time slots or mini-slots are aggregated together and used for communication between UE 115 and base station 105.

[0086] In some cases, the UE 115 may continuously monitor the communication link 125 for an indication that the UE 115 may receive data. In other cases (e.g., to save power and extend battery life), the UE 115 may be configured with a DRX cycle. The DRX cycle consists of an "on duration" when the UE 115 may monitor control information (e.g., on the PDCCH) and a "DRX cycle" when the UE 115 may power off the radio component. The DRX cycle (e.g., for connected mode DRX) may be used to effectively use battery power to receive downlink transmissions. In some cases, the base station 105 and the UE 115 may establish an RRC connection, and the UE 115 may enter a sleep state during inactive communications. For example, during RRC connection establishment, a DRX configuration may be configured in an RRC connection establishment request or an RRC connection reconfiguration request, including a DRX on cycle duration and a DRX off cycle duration. The DRX configuration may determine how frequently the UE 115 is scheduled to wake up and receive downlink data based on the configured DRX cycle duration. The UE 115 may wake up during the DRX on-duration and monitor one or more physical downlink control channel (PDCCH) subframes for downlink control information (DCI) designated for the UE 115, including a radio network temporary identifier (RNTI) (e.g., a cell-specific RNTI (C-RNTI) and subsequent physical downlink shared channel (PDSCH) transmissions.

[0087] In some cases, UE 115 may be configured with a short DRX cycle and a long DRX cycle. In some cases, if UE 115 is inactive for one or more short DRX cycles, it may enter a long DRX cycle. The transition between short DRX cycle, long DRX cycle and continuous reception may be controlled by an internal timer or by a message from base station 105. UE 115 may receive a scheduling message on PDCCH during the on-duration period. While monitoring the PDCCH for the scheduling message, UE 115 may initiate a "DRX inactive timer". If the scheduling message is successfully received, UE 115 may be ready to receive data, and the DRX inactive timer may be reset. When the DRX inactive timer expires without receiving a scheduling message, UE 115 may move to a short DRX cycle and may start a "DRX short cycle timer". When the DRX short cycle timer expires, UE 115 may resume the long DRX cycle.

[0088] The DRX cycle (e.g., when operating in DRX mode) can be used to make battery power effectively used to receive downlink transmissions. The base station 105 and the UE 115 can establish an RRC connection, and the UE 115 can enter a sleep state when there is no active communication. For example, during the RRC connection establishment, the DRX configuration can be configured in the RRC connection establishment request or the RRC connection reconfiguration request, including the DRX on cycle duration and the DRX off cycle duration. The DRX configuration can determine how often the UE 115 is scheduled to wake up and receive downlink data according to the configured DRX cycle duration. The UE 115 can wake up during the DRX on duration and monitor one or more physical downlink control channel (PDCCH) subframes for downlink control information (DCI) specified for the UE 115, including a radio network temporary identifier (RNTI) (e.g., a cell-specific RNTI (C-RNTI) and subsequent physical downlink shared channel (PDSCH) transmissions.

[0089] The term "carrier" refers to a set of radio spectrum resources having a defined physical layer structure for supporting communications on the communication link 125. For example, a carrier of the communication link 125 may include a portion of a radio spectrum band that operates according to a physical layer channel for a given radio access technology. Each physical layer channel may carry user data, control information, or other signaling. A carrier may be associated with a predefined frequency channel (e.g., an E-UTRA Absolute Radio Frequency Channel Number (EARFCN)) and may be located according to a channel grid so as to be discovered by a UE 115. A carrier may be downlink or uplink (e.g., in FDD mode), or may be configured to carry downlink communications and uplink communications (e.g., in TDD mode). In some examples, a signal waveform transmitted on a carrier may be composed of multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as orthogonal frequency division multiplexing (OFDM) or DFT-s-OFDM).

[0090] The organization structure of the carrier may be different for different radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR, etc.). For example, communications on a carrier may be organized based on TTIs or time slots, each of which may include user data and control information or signaling to support decoding of the user data. The carrier may also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate the operation of the carrier. In some examples (e.g., in a carrier aggregation configuration), the carrier may also have acquisition signaling or control signaling to coordinate the operation of other carriers.

[0091] Physical channels may be multiplexed on a carrier according to various techniques. Physical control channels and physical data channels may be multiplexed on a downlink carrier using, for example, time division multiplexing (TDM), frequency division multiplexing (FDM), or hybrid TDM-FDM techniques. In some examples, control information sent in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or common search space and one or more UE-specific control regions or UE-specific search spaces).

[0092] A carrier can be associated with a particular bandwidth of the radio spectrum, and in some examples, the carrier bandwidth can be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth can be one of a plurality of predetermined bandwidths of a carrier for a particular radio access technology (e.g., 1.4 MHz, 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). In some examples, each served UE 115 can be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 can be configured to operate using a narrowband protocol type associated with a predefined portion or range (e.g., a set of subcarriers or RBs) within a carrier (e.g., an "in-band" deployment of a narrowband protocol type).

[0093] In a system using MCM technology, a resource element may consist of a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period is inversely proportional to the subcarrier spacing. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme). Therefore, the more resource elements received by UE 115 and the higher the modulation scheme, the higher the data rate available to UE 115. In a MIMO system, wireless communication resources may refer to a combination of radio spectrum resources, time resources, and space resources (e.g., space layers), and the use of multiple space layers may further increase the data rate used to communicate with UE 115.

[0094] A device of the wireless communication system 100 (e.g., a base station 105 or a UE 115) may have a hardware configuration that supports communication on a specific carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 and / or a UE 115 that may support simultaneous communication via carriers associated with more than one different carrier bandwidths.

[0095] The wireless communication system 100 may support communication with the UE 115 on multiple cells or carriers, a feature that may be referred to as carrier aggregation (CA) or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured with multiple downlink CCs and one or more uplink CCs. Carrier aggregation may be used with FDD and TDD component carriers.

[0096] In some cases, the wireless communication system 100 can utilize an enhanced component carrier (eCC). An eCC can be characterized by one or more characteristics, including a wider carrier or frequency channel bandwidth, a shorter symbol duration, a shorter TTI duration, or a modified control channel configuration. In some cases, an eCC can be associated with a carrier aggregation configuration or a dual connectivity configuration (e.g., when multiple serving cells have suboptimal or non-ideal backhaul links). An eCC can also be configured for use in an unlicensed spectrum or a shared spectrum (e.g., allowing more than one operator to use the spectrum). An eCC characterized by a wide carrier bandwidth can include one or more segments that can be utilized by a UE 115, which may not be able to monitor the entire carrier bandwidth, or can otherwise be configured to use a limited carrier bandwidth (e.g., to save power).

[0097] In some cases, an eCC may utilize a different symbol duration than other CCs, which may include using a reduced symbol duration compared to the symbol duration of other CCs. A shorter symbol duration may be associated with an increased spacing between adjacent subcarriers. A device utilizing an eCC (such as a UE 115 or a base station 105) may transmit a wideband signal (e.g., according to a frequency channel or carrier bandwidth of 20 MHz, 40 MHz, 60 MHz, 80 MHz, etc.) at a reduced symbol duration (e.g., 16.67 microseconds (μs)). A TTI in an eCC may consist of one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

[0098] Wireless communication systems such as NR systems can utilize any combination of licensed spectrum bands, shared spectrum bands, and unlicensed spectrum bands. The flexibility of eCC symbol duration and subcarrier spacing can allow eCC to be used across multiple spectrums. In some examples, NR shared spectrum can improve spectrum utilization and spectrum efficiency, particularly through dynamic vertical resource sharing (e.g., in the frequency domain) and horizontal (e.g., in the time domain) resource sharing.

[0099] The wireless communication system 100 may support the use of an adaptive monitoring configuration for RS measurements within the system. For example, the UE 115 may utilize an effective modification to the RS measurement configuration, which may be based on the conditions of the UE 115 (e.g., mobility, DRX, channel condition experience, etc.). The RS measurement may be used for intra-cell (e.g., within the coverage area 110 of the base station 105) channel quality measurement or inter-cell (e.g., between different coverage areas 110 of the base station 105) channel quality measurement. For example, RS measurements may be used for BM, RRM, RLM, channel tracking, etc. A plurality of measurement configurations may be provided for the UE 115. In some cases, each of the plurality of measurement configurations may include a different set of measurement parameters (e.g., measurement periodicity and window) for measuring the RS of the cell. The UE 115 may be configured with one or more measurement configurations and may be able to implicitly activate, deactivate, and / or switch between different measurement configurations based on changes in conditions experienced by the UE 115 or based on signaling from the base station 105.

[0100] Changes to previously used measurement configurations may be done on a clearly, unambiguously defined timeline to reduce latency, excessive signaling, unnecessary measurements, etc. In some cases, one or more of the base stations 105 may include a base station measurement configuration manager that may determine different measurement configurations that may be used by the UE 115. The base station 105 may then select one of the measurement configurations, for example, based on beam and UE 115 conditions. The base station 105 may then communicate which measurement configuration the UE 115 should operate on. In some cases, the base station 105 may signal the UE 115 to activate, deactivate, and / or switch to a measurement configuration.

[0101] The UE 115 may include a UE measurement configuration manager that may receive signaling related to different measurement configurations of the UE 115. The UE 115 may then determine a specific measurement configuration with determined parameters and reporting schemes based on the signaling received from the base station 105. In some cases, the UE 115 may not receive an explicit signal indicating which measurement configuration to use. In these cases, the UE 115 may change operating modes, which may trigger a change in one or more measurement configurations (or a change in parameters of the measurement configuration). For example, a change from DRX operation to active operation may trigger a change in the measurement configuration (e.g., measurement frequency and opportunity timeline). In some cases, the UE 115 may perform measurements at additional times (e.g., sub-sampling periods) based on receiving an indication from the base station 105.

[0102] Figure 2An example of a system 200 for wireless communication supporting adaptive monitoring according to aspects of the present disclosure is shown. In some examples, the wireless communication system 200 can implement aspects of the wireless communication system 100. The wireless communication system 200 can include a UE 115-a and base stations 105-a and 105-b, which can be examples of corresponding devices described herein.

[0103] UE 115-a may communicate with base station 105-a using beams 205-a and 210-a. UE 115-a may perform RS measurements on beam 205-a of base station 105-a and / or beam 205-b of base station 105-b. In a system using beamforming, such as wireless communication system 200, mobility considerations for UE 115-a may include intra-cell mobility and inter-cell mobility. In some examples, intra-cell mobility may refer to the ability of UE 115-a to move within a single cell (e.g., the cell of base station 105-a), and BM may be used to monitor channel conditions and ensure that beam 205-a is successfully received from base station 105-a of the cell at UE 115-a. In some cases, BM may occur using layer 1 (L1) and / or layer 2 (L2) signaling. In some examples, inter-cell mobility may refer to the ability of UE 115-a to move between cells (e.g., a cell of base station 105-a and a cell of base station 105-b), and RRM may be used to monitor channel conditions and allow successful transitions between cells. Radio resource management may use layer 3 (L3) signaling. However, there may be no dedicated mobility signaling in L1, L2, or L3 signaling.

[0104] Key functions related to multi-beam mobility may be related to feedback reporting within the wireless communication system 200. In particular, a cell-specific reference signal (CRS) function may be included in a synchronization signal block (SSB) (e.g., including one or more synchronization signals and / or broadcast channels) and / or a channel state information (CSI) reference signal (CSI-RS). For example, different RS measurement techniques such as RRM, BM, RLM, and channel tracking may be based on one or both of the SSB and the CSI-RS. In some cases, the CSI-RS may include, for example, a tracking (or third-level) reference signal (TRS) for location tracking of the UE 115. RRM may be performed for a serving cell of the UE 115-a (e.g., associated with the base station 105-a) and / or a neighboring cell of the UE 115 (e.g., associated with the base station 105-b). In addition, BM, RLM, and channel tracking may be performed on the serving cell of the UE 115-a. In NR systems such as the wireless communication system 200, RRM, BM, RLM, and channel tracking may be complex due to beamforming and variable subcarrier spacing.

[0105] RRM can be used for various resource measurements based on multiple beams, and can be triggered to report these measurements based on various factors. For example, RRM may include measurement results per SSB and / or physical broadcast channel (PBCH) block. In another example, RRM may include measurement results per cell based on SSB and / or PBCH blocks. When the result is per cell, the cell measurement may be configured to return the highest measured beam among the SSB beams, or may be configured as a linear average of some of the highest configured SSB beams. In some examples, RRM may include measurement results per CSI-RS resource. In some examples, RRM may include measurement results per cell based on CSI-RS resources. When the result is per cell based on CSI-RS, the cell measurement may be configured to return the highest measured beam among the CSI-RS beams, or may be configured as a linear average of some of the highest configured CSI-RS beams.

[0106] The RRM measurement report trigger may occur with multiple events. For example, when the serving cell measurement exceeds (e.g., becomes better than) a threshold, the RRM measurement report may be triggered. In another example, when the serving cell measurement drops below a threshold, the RRM measurement report may be triggered. In another example, when the neighboring cell becomes better than a special cell (SpCell) offset, the RRM measurement report may be triggered. In another example, when the neighboring cell exceeds (e.g., becomes better than) a threshold, the RRM measurement report may be triggered. In another example, when the SpCell drops below (e.g., becomes worse than) a first threshold and the neighboring cell exceeds (e.g., becomes better than) a second threshold, the RRM measurement report may be triggered. In another example, when the neighboring cell becomes better than a second cell (SCell) offset, the RRM measurement report may be triggered.

[0107] UE 115-a may be able to receive communications using beamforming techniques. In some cases, UE 115-a may perform reference signal measurements of base station 105-a and / or base station 105-b. UE 115-a may be configured to perform RRM, BM and / or RLM at different times. For example, RRM (e.g., SSB-based and CSI-based) may be performed by UE 115-a to perform intra-cell and inter-cell measurements without a measurement gap (MG). In some cases, when MG is not used, RRM may be performed in a configured SSB measurement timing configuration (SMTC) window. In other examples, RRM (e.g., SSB-based and CSI-based) may be performed to perform intra-cell and inter-cell measurements in the case of MG. In these cases, RRM may be performed in a configured MG, which may overlap with the SMTC window in time and / or frequency when MG is used. BM and / or RLM may be performed by UE 115-a for configured reference signals (e.g., SSB and / or CSI-RS). In some cases, there are no specific instances defined for when to perform BM and RLM measurements. UE 115-a may perform BM measurements at a certain number of intervals (e.g., the shortest periodicity of the configured RS, 2ms). In addition or alternatively, UE 115-a may perform RLM measurements while in normal (e.g., non-discontinuous reception (non-DRX)) mode with a certain periodicity (e.g., the shortest periodicity of the configured RS, 10ms). UE 115-a may also perform RLM measurements, for example, while in DRX mode with a certain periodicity (e.g., the shortest periodicity of the configured RS and DRX periodicities). The network may configure UE 115-a to perform measurements for SSB or CSI-RS. However, in some cases, UE 115-a may not be obligated to perform measurements. That is, the time frame in which UE 115-a performs measurements may be ambiguous or undefined.

[0108] The varying number of measurements and configurations for RRM, BM, and RLM on multiple beams (e.g., all beams) may have an impact on UE 115-a performance. For example, due to the high resource requirements of RRM, BM, and RLM, the network may encounter scheduling limitations for transmitting to UE 115-a. Scheduling limitations may be due to the use of different receive beams associated with RRM, BM, and RLM. The use of different subcarrier spacings for reference signals (e.g., SSB and CSI-RS) may be another example source of scheduling limitations. Scheduling limitations may also occur due to the use of measurement gaps for intra-cell and inter-cell frequency measurements, for example, the network may not schedule transmissions for UE 115-a when there are measurement gaps. In some cases, another impact of RRM, BM, and RLM may include unnecessary power consumption at UE 115-a when measurements are performed more frequently than required. In some cases, UE 115-a may require more frequent RRM, BM, and RLM in a high mobility state and may require less frequent RRM, BM, and RLM than when UE 115-a is in a more stationary state.

[0109] In some cases, the process for changing individual measurement configurations (e.g., for RRM, BM, and RLM) may be accomplished via RRC signaling. However, the changes via RRC may be semi-static and may not change the configuration in a valid time (e.g., to account for rapidly changing conditions at UE 115-a). Further, the timeline for UE 115-a to use the updated measurement configuration indicated by RRC signaling may be unclear or not clearly defined. The timeline as to the exact time when UE 115-a should begin using the updated measurement configuration may be ambiguous.

[0110] For BM and RLM, when the measurements performed by UE 115-a are not clearly defined, the network may unnecessarily assume that all beams are needed for measurement. Adaptive monitoring for RLM, BM, and RRM can be used to minimize scheduling constraints of the network and unnecessary power consumption at UE 115-a. When the conditions of UE 115-a change (e.g., UE 115-a speed increases), UE 115-a can adjust the parameters used for RS measurements. The change can be the result of signaling from a serving base station (e.g., base station 105-a) or can be triggered by a change in the operating state at UE 115-a.

[0111] As described in further detail below, adaptive monitoring can be implemented in the wireless communication system 200 to mitigate challenges associated with changing types of measurements for different beams and changing mobility conditions of the UE 115-a. For example, the base station 105-a can provide multiple measurement configurations 220 to the UE 115-a. The multiple measurement configurations can be issued via RRC signaling (e.g., within a single information element of an RRC message). The base station 105-a can also issue additional signaling (e.g., via DCI or MAC-CE), which activates, deactivates and / or switches to one of the multiple measurement configurations. In addition or alternatively, the base station 105-a can perform subsampling on the measurement occasions associated with the measurement configuration and indicate adjustments to the measurement parameters (e.g., periodicity, timing, offset, etc.) of the measurement configuration. In other examples, the UE 115-a can determine the adjustments in the measurement configuration, for example, based on the UE 115-a being in DRX mode.

[0112] Figure 3 An example of a timeline 300 supporting adaptive monitoring according to aspects of the present disclosure is shown. In some examples, the timeline 300 can implement aspects of the wireless communication system 100. The timeline 300 can include a UE 115-b, which can be an example of a corresponding device described herein. The UE 115-b can be configured to perform RS measurements such as BM, RLM, and RRM for a cell.

[0113] In some cases, UE 115-b may operate in normal (e.g., RRC_Connected) mode. The mode may include an activity duration 305 when UE 115-b may send and receive communications (e.g., data). The mode may also include configured measurement parameters. For example, UE 115-b may perform RS measurements based on scheduling (e.g., a specific periodicity of MG 310). In some cases, when operating in RRC_Connected mode, UE 115-b may use adaptive monitoring. Adaptive monitoring may include using multiple measurement configurations. For example, there may be multiple measurement configurations for each of BM, RLM, and RRM. These multiple measurement configurations may be signaled to UE 115-b via a single RRC transmission, and may also include multiple SMTC configurations to be used by UE 115-b for RRM measurements without requiring an MG.

[0114] In other examples, multiple MG configurations may be included and the MG configurations may be used by UE 115-b for RRM measurements in the case of MG 310. In some examples, multiple measurement configurations for BM and RLM may be included; these may be linked to RS configurations (e.g., SSB or CSI-RS) or may be independent of RS configurations. In some examples, different configurations may include different periodicities for SMTC and MG 310 and different time domain windows for SMTC and MG 310. For example, the offset and periodicity of the SMTC window may be indicated to determine a specific monitoring / measurement instance. In other cases, there may not be an explicit measurement window with certain RS configurations, and the default measurement configuration may be configured or indicated by the network.

[0115] Adaptive monitoring may provide the ability to activate, deactivate, and / or switch to one of the configurations via control signaling. For example, the control signaling may include MAC-CE or DCI. The timelines for MAC-CE and DCI signaling may be more clearly defined than RRC and may be more frequent than RRC (e.g., 10 ms of RRC delay compared to 2 ms delay). This may allow UE 115-b to avoid the ambiguous timelines associated with RRC reconfiguration, and UE 115-b may experience faster switching compared to RRC reconfiguration. In some cases, UE 115-b may also receive control signaling from another carrier indicating a change in the measurement configuration.

[0116] For example, UE 115-b may operate in active duration 305-a and receive control signaling (e.g., via MAC-CE or DCI) from a base station at 315-a. The control signaling may switch UE 115-b to a different measurement configuration that may be predefined including MG 310. The measurement configuration may include the timing and frequency of when MG 310 will and UE 115-b should perform RS measurements within MG 310. UE 115-b may follow the first measurement configuration in multiple MGs 310-a and active durations 305-b and 305-c. In active duration 305, UE 115-b may not perform RS measurements.

[0117] UE 115-b operating in active duration 305-c may be configured using the first measurement configuration received at 315-a. UE 115-b may receive additional control signaling at 315-b. The additional control signaling may be included in a MAC-CE or DCI. In addition or alternatively, the control signaling may be received on a different carrier or bandwidth part (BWP). In some examples, UE 115-b may send an acknowledgment (ACK) to the base station in response to the additional control signaling at 315-b. In some cases, changes to the measurement configuration at the base station and / or UE 115-b may be based on an ACK sent by UE 115-b, and application of the updated measurement configuration may be performed relative to the additional control signaling or ACK.

[0118] The control signaling at 315-b may instruct UE 115-b to deactivate the current measurement configuration. Thus, UE 115-b may not perform RS measurements in MG 310-b, but may operate in active duration 305-c until, for example, further control signaling is received.

[0119] In some examples, adaptive monitoring may include alternative or additional options for configuring multiple measurement configurations. For example, the use of sub-sampling of measurement opportunities may be introduced. Sub-sampling may include defined rules from RS configuration. Another alternative or additional technique may include using explicit MAC-CE or DCI commands to activate, deactivate, or switch to different measurement periodicities or opportunities. The ability to use different RS measurement periodicities and adaptable measurement windows may allow UE 115-b and the network to perform BM, RLM, RRM, and data transmission more efficiently.

[0120] Figure 4 An example of a timeline 400 supporting adaptive monitoring according to aspects of the present disclosure is shown. In some examples, the timeline 400 can implement aspects of the wireless communication system 100. The timeline 400 can include a UE 115-c, which can be an example of a corresponding device described herein. The UE 115-c can be configured to perform RS measurements such as BM, RLM, and RRM for a cell. The timeline 400 can, for example, illustrate an implicit adaptation of the UE 115-c to a measurement configuration based on a DRX cycle.

[0121] In some examples, UE 115-c may operate in a connected discontinuous reception (CDRX) mode, wherein UE 115-c may be in RRC_Connected mode and a receive sleep cycle. When operating in CDRX mode, UE 115-c may use implicit adaptive monitoring. For example, since measurement adaptation is associated with the CDRX state of UE 115-c, when UE 115-c enters CDRX operation, UE 115-c may switch to a larger measurement periodicity. In another example, when UE 115-c exits CDRX operation, UE 115-c may switch to a smaller measurement periodicity to save power.

[0122] As shown, UE 115-c can operate in a CDRX mode having a DRX cycle 415-a including an active duration 405-a and an inactive duration 410-a. During the active duration 405-a, UE 115-c can enable a receiving component and perform RS measurements on a serving cell and / or a neighboring cell. UE 115-c can be configured with a first measurement configuration that defines RS measurement parameters for both the active duration 405-a and the inactive duration 410-a of the DRX cycle 415-a. These parameters may include measurement periodicity and may be related to the DRX cycle 415-a and the active duration 405-a. In some cases, RS measurements may be configured and / or performed during the inactive duration 410-a, since it may not always be possible to align the RS timing with the active duration 405-a.

[0123] After the inactive duration 410-b, the UE 115-c may operate according to a different DRX cycle 415-b including the active duration 405-c and the inactive duration 410-c. The DRX cycle 415-b may be shorter than the DRX cycle 415-a and, therefore, the measurement configuration of the UE 115-c may be adapted. The UE 115-c may detect this change in DRX operation as a trigger to update measurement parameters. The UE 115-c may be configured with a second measurement configuration that defines RS measurement parameters for both the active duration 405-c and the inactive duration 410-c of the DRX cycle 415-b. These parameters may include measurement periodicity and may be related to the DRX cycle 415-b and the active duration 405-c. For example, the UE 115-c may be updated to a second measurement configuration that may increase the periodicity of RS measurements with a shorter DRX cycle 415-b compared to the first measurement configuration. In some cases, the adaptation of the RS measurement configuration may be independent of changes in CDRX parameters (eg, changes in the DRX cycle 415).

[0124] The measurement periodicity may be associated with the DRX cycle 415. For example, a larger measurement periodicity may be used with a longer DRX cycle (e.g., 415-a). In some cases, the measurement occasions may be defined based on the DRX activity occasions (e.g., 405). The UE 115-c may not receive an explicit signal to adapt its measurement periodicity, but rather the UE 115-c may implicitly know to change its measurement periodicity based on switching to or from a CDRX mode to a different DRX cycle 415 duration.

[0125] Figure 5 An example of a process flow 500 of a system supporting adaptive monitoring according to aspects of the present disclosure is shown. In some examples, the process flow 500 can implement aspects of the wireless communication system 100. For example, the process flow 500 includes a UE 115-d and a base station 105-c, which can be a reference Figure 1 and Figure 2 Examples of corresponding devices are described. Process flow 500 may illustrate a system that supports dynamic selection of measurement configurations for UE 115.

[0126] At 505, UE 115-d may receive a first message indicating one or more measurement configurations, and base station 105-c may send the message. Each measurement configuration may include a different set of measurement parameters for the RS of the measured cell. In some cases, the RS may be from a cell provided by base station 105-c or from a neighboring cell. In some cases, the RS may be a synchronization signal (SS) block (or SS burst), a CSI-RS, or any combination thereof. In addition, the first message may be sent via RRC signaling (e.g., an RRC information element may include an indication of multiple measurement configurations).

[0127] At 510, UE 115-d may receive (from base station 105-c) a second message indicating that UE 115-d activates a first measurement configuration, deactivates the first measurement configuration, or switches to the first measurement configuration, where the first measurement configuration is from one or more measurement configurations. In some cases, the second message may be received via DCI, or via MAC-CE, or via a different carrier, or via a different BWP (e.g., a BWP other than the BWP on which the RS is received), or a combination thereof. At 515, UE 115-d may determine a measurement reporting scheme based at least in part on the indication of activating, deactivating, or switching to the first measurement configuration.

[0128] For example, at 515, UE 115-d may determine a measurement parameter set for the first measurement configuration based on a second message indicating that UE 115-d activates the first measurement configuration. In these cases, UE 115-d may identify that the measurement parameter set includes an SMTC window configuration selected from a plurality of SMTC window configurations. In some cases, the SMTC window configuration includes an SMTC window periodicity, or an SMTC window size, or an SMTC window offset, or a combination thereof. Additionally or alternatively, UE 115-d may identify that the measurement parameter set includes a measurement gap configuration selected from a measurement gap configuration set, wherein the measurement gap configuration may include a measurement gap periodicity, or a measurement gap size, or a combination thereof.

[0129] In some cases, the UE 115-d may identify that the set of measurement parameters includes an RS measurement configuration for performing measurements of the RS of the cell, the RS measurement configuration including a measurement periodicity, or a measurement window size, or a combination thereof. In some examples, the RS measurement configuration may correspond to a configuration of the RS of the cell, or be independent of a configuration of the RS of the cell. In addition or alternatively, the RS measurement configuration may indicate different types of RS to be measured. In some cases, the UE 115-d may identify that the set of measurement parameters includes a beam set for monitoring RS, or activating inter-frequency measurements, or deactivating inter-frequency measurements, or a combination thereof.

[0130] In any case, at 525, the UE 115-d may, after determining the measurement reporting scheme, perform measurements of the RS according to the determined set of measurement parameters, and then send a measurement report to the base station 105-c at 530. In these cases, the measurement report may include measurements of the RS based on the measurement reporting scheme.

[0131] Additionally or alternatively, the message received by UE 115-d at 535 (or the second message received at 510) may include an indication to deactivate the first measurement configuration. In some cases, the indication may provide a timeline for deactivating the measurement configuration. Thus, after receiving the indication to deactivate the first measurement configuration, UE 115-d may stop measuring the RS using the first measurement configuration based on the message instructing UE 115-d to deactivate the first measurement configuration.

[0132] In some cases, the UE 115-d may perform measurements of the RS using the second measurement configuration, and may then switch to the first measurement configuration, for example, based on the message received at 535 indicating that the UE 115-d is switching to the first measurement configuration (or the second message received at 510) at 540. In this way, the UE 115-d may determine a set of measurement parameters for the first measurement configuration, wherein the set of measurement parameters for the first measurement configuration is different from the set of measurement parameters for the second measurement configuration, and the UE 115-d may perform measurements of the RS based on the determined set of measurement parameters. At 545, the UE 115-d may send a measurement report including the measurements of the RS to the base station 105-c based on the measurement reporting scheme.

[0133] Figure 6 600 of a system supporting adaptive monitoring according to aspects of the present disclosure. In some examples, the process flow 600 can implement aspects of the wireless communication system 100. For example, the process flow 600 includes a UE 115-e and a base station 105-d, which can be a reference Figure 1 and Figure 2 Examples of corresponding devices are described. Process flow 600 may illustrate a system that supports implicit adaptation of measurement configuration for UE 115.

[0134] At 605, the base station 105-d may send a message indicating one or more measurement configurations for measuring RSs of a cell, and the UE 115-e may receive the message. At 610, the UE 115-e may perform measurements of the RSs according to a first periodicity of the measurement configurations.

[0135] At 615, the UE 115-e may enter the CDRX mode and may then perform measurements of the RS of the cell according to the second periodicity of the measurement configuration at 620. Adjustments to the measurement configuration and periodicity may be based on the CDRX mode, where the first periodicity may be different from the second periodicity. For example, the first periodicity may be shorter than the second periodicity, and thus measurements may be performed less frequently.

[0136] At 625, the UE 115-e may exit the CDRX mode and may perform measurements of the RS according to a third periodicity, where the third periodicity may be, for example, shorter than the second periodicity. In other cases, the third periodicity may be greater than the second periodicity based on conditions of the UE 115-e. In any case, the UE 115-e may adjust the measurement period based on the CDRX mode, and in some cases may be defined by the CDRX mode.

[0137] Figure 7A block diagram 700 of a device 705 supporting adaptive monitoring according to aspects of the present disclosure is shown. The device 705 may be an example of aspects of the UE 115 as described herein. The device 705 may include a receiver 710, a measurement configuration manager 715, and a transmitter 720.

[0140] The measurement configuration manager 715 may also receive a first message from the base station 105 indicating the measurement configuration of the RS for measuring the cell; receive a second message from the base station 105 indicating the UE 115 activating the first measurement parameter set of the measurement configuration, deactivating the first measurement parameter set, or switching to the first measurement parameter set; and determine a measurement reporting scheme based on the indication of activating, deactivating, or switching to the first measurement parameter set.

The information may be passed to other components of the device 805. The receiver 810 may be a reference Fig.10 Examples of aspects of the transceiver 1020 are described.

[0153] Fig. 9A block diagram 900 of a measurement configuration manager 905 supporting adaptive monitoring according to aspects of the present disclosure is shown. The measurement configuration manager 905 may be an example of aspects of the measurement configuration manager 715, the measurement configuration manager 815, or the measurement configuration manager 1010 described herein. The measurement configuration manager 905 may include a measurement parameter identifier 910, a measurement controller 915, a reporting scheme identifier 920, a feedback manager 925, a deactivation controller 930, a handover controller 935, a periodicity controller 940, and a DRX controller 945. Each of these modules may communicate with each other directly or indirectly (e.g., via one or more buses).

[0154] The measurement parameter identifier 910 may receive a first message indicating a measurement configuration set from a base station, each measurement configuration in the measurement configuration set including a different measurement parameter set for measuring the RS of the cell. In some examples, the measurement parameter identifier 910 may receive a first message indicating a measurement configuration for measuring the RS of the cell from a base station.

In some examples, the measurement parameter identifier 910 may identify that the measurement parameter set includes a beam set for monitoring RS, or activating inter-frequency measurement, or deactivating inter-frequency measurement, or a combination thereof.

[0157] In some examples, the measurement parameter identifier 910 may determine a measurement parameter set of a first measurement configuration, wherein the measurement parameter set of the first measurement configuration is different from the measurement parameter set of the second measurement configuration.
