Abstract

Methods, systems, and devices for wireless communication are described. Some wireless communication systems support user equipment (UE) to achieve power savings by operating in connected discontinuous reception (C-DRX) mode. The system can additionally utilize wake-up signals for further UE power savings. For example, the UE can be configured with a wake-up signal resource configuration (e.g., a first search space configuration) for monitoring wake-up signals when operating in a low power mode. The first search space configuration can be different from the second search space configuration for the UE operating in an active mode. When in the low power mode, the UE can monitor wake-up signals according to the wake-up signal resource configuration. If the UE receives a wake-up signal in the wake-up signal resources defined by the configuration, the UE can initiate a wake-up procedure and transition to an active mode for data transmission and reception.

[0002] This patent application claims priority to U.S. patent application No. 16 / 592,675, entitled “WAKEUP SIGNALING RESOURCE OCCASIONS,” filed by NAM et al. on October 3, 2019, and U.S. provisional patent application No. 62 / 742,227, entitled “WAKEUP SIGNALING RESOURCE OCCASIONS,” filed by NAM et al. on October 5, 2018, which are assigned to the assignee of this application.

[0003] background

[0004] The following relates generally to wireless communications, and more particularly to wake-up signaling resource opportunities.

[0005] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcasting, etc. These systems may be able to 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 (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 use various 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 spread OFDM (DFT-S-OFDM). A wireless multiple access communication system may include several base stations or network access nodes, each of which simultaneously supports the communication of multiple communication devices, which may be referred to as user equipment (UE).

[0006] Some wireless communication systems may support UEs operating in a discontinuous reception (DRX) mode (e.g., a connected DRX (C-DRX) mode), wherein the UE may transition between an active state for data transmission and reception and a sleep state for power saving. The UE may determine whether data is available by monitoring a control channel, such as a physical downlink control channel (PDCCH). The PDCCH may carry or otherwise convey an indication that a base station has data ready to be transmitted to the UE. In some cases, in order to reduce the frequency of control channel monitoring, the UE may monitor the wake-up signal using a low complexity receiver, and if no wake-up signal is received, the UE may skip the control channel monitoring opportunity. However, in a system with a large number of UEs, even though the base station does not schedule the UE for any data communication, the UE may still detect a wake-up signal intended for other UEs and may perform a wake-up procedure. These unnecessarily awakened UEs may experience reduced power savings due to incorrectly identified wake-up signals.

[0007] Overview

[0008] The described technology relates to improved methods, systems, devices, and apparatuses that support wake-up signaling resource opportunities. In general, the described technology provides improved power saving at user equipment (UE). Some wireless communication systems support UEs to achieve power saving by operating in a connected discontinuous reception (C-DRX) mode. The system may additionally utilize a wake-up signal for further power saving at the UE. For example, the UE may be configured with a wake-up signal resource configuration (e.g., a first search space set configuration) that varies from UE to UE or from UE group to UE. The wake-up signal resource configuration may indicate several resource configuration parameters, such as time resource information, frequency resource information, decoding parameter information, beam sweep information, or some combination of these parameters. When in low power mode, the UE may monitor the wake-up signal according to the wake-up signal resource configuration and corresponding parameters. If the UE receives a wake-up signal in a wake-up signal resource defined by the configuration, the UE may determine that the wake-up signal is intended for the UE (e.g., based on configuration parameters). Based on the determination, the UE may initiate a wake-up procedure and transition to an active mode for data transmission and reception. When in active mode, the UE may monitor downlink control information (DCI) messages according to a second search space set configuration that is different from the first search space set configuration. Additionally, when in low power mode, if the UE detects a wake-up signal that does not correspond to a wake-up signal resource configuration for the UE, the UE may determine that the wake-up signal is intended for a different UE and may not wake up. In this way, the UE may better distinguish between wake-up signals transmitted by the base station, reduce the number of unnecessary wake-up procedures performed by the UE, and correspondingly improve power saving at the UE.

[0074] Detailed Description

[0075] Some wireless communication systems (e.g., millimeter wave (mmW) systems) may support user equipment (UE) operating in a discontinuous reception (DRX) mode (e.g., a connected DRX (C-DRX) mode). In C-DRX mode, the UE may transition between an active state for data transmission and reception and a sleep state for power saving. The UE may determine whether data is available by monitoring a control channel, such as a physical downlink control channel (PDCCH). The PDCCH may carry or otherwise convey an indication that a base station has data ready to be transmitted to the UE or is scheduling the UE for data transmission. In some cases, in order to reduce the frequency of control channel monitoring, the UE may use a low-complexity receiver to monitor wake-up signals while in a low-power mode. If the UE detects a wake-up signal transmitted by a base station (e.g., on a downlink control channel or another channel), the UE may transition to a higher power mode in order to monitor the control channel for scheduling information. However, if the UE does not detect a wake-up signal transmitted by a base station, the UE may skip the full-power control channel monitoring opportunity and instead return to a deep sleep mode, thereby improving power saving at the UE.

[0076] In some cases, a base station may serve a large number of UEs within a cell. In order to use the wake-up signal efficiently, the base station may distinguish the wake-up signal intended for each UE or UE group based on the wake-up signal resource configuration. For example, each UE or UE group may be configured with a specific wake-up signal resource configuration, wherein the wake-up signal resource configuration indicates how the UE or UE group monitors the wake-up signal, decodes the wake-up signal, or both. If a UE or UE group detects a wake-up signal transmitted according to the wake-up signal resource configuration for the UE or UE group, the UE or UE group may initiate a wake-up procedure according to the wake-up signal. However, if the UE detects a wake-up signal transmitted according to a different wake-up signal resource configuration, the UE may determine that the wake-up signal is intended for a different UE or UE group, and the wake-up procedure may not be performed.

[0077] The wake-up signal resource configuration may indicate several resource configuration parameters. These resource configuration parameters may include time resource information (e.g., the start symbol index and the duration of the monitoring period), frequency resource information, decoding parameter information (e.g., scrambling sequence, downlink control information (DCI) format, radio network temporary identifier (RNTI), decoding assumptions, or some combination of these parameters for successfully decoding the wake-up signal), beam sweep information (e.g., the number of beams, beam repetition factor, beam pattern, etc.), or some combination of these parameters or other related parameters. If the UE receives a wake-up signal during the monitoring opportunity defined by the wake-up signal resource configuration and successfully decodes the wake-up signal according to the decoding parameters defined by the wake-up signal resource configuration, the UE may determine that the wake-up signal is intended for the UE. Accordingly, the UE may perform a wake-up procedure to transition to a higher power mode and monitor scheduling information. In the higher power mode (e.g., active power mode), the UE may operate according to a configuration different from the wake-up signal resource configuration. For example, the wake-up signal resource configuration may be a first search space configuration (eg, a first search space set), and the active power mode configuration may be a second search space configuration (eg, a second search space set).

[0078] Various aspects of the present disclosure are initially described in the context of a wireless communication system. Additional aspects of the present disclosure are described with respect to timelines (e.g., UE operation timelines, UE power level timelines, wake-up procedure timelines, etc.), configurations for wake-up signal resources, and process flows. Various aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow charts relating to wake-up signaling resource opportunities.

[0079] Figure 1 An example of a wireless communication system 100 supporting wake-up signaling resource opportunities according to various aspects of the present disclosure is illustrated. 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 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-APro network, or a new radio (NR) network. In some cases, the wireless communication system 100 may support enhanced broadband communications, ultra-reliable (e.g., mission-critical) communications, low latency communications, or communications with low-cost and low-complexity devices.

[0080] 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 transceiver station, a radio base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a home Node B, a home evolved Node B, 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 equipment (including macro eNBs, small cell eNBs, gNBs, relay base stations, etc.).

[0081] Each base station 105 may be associated with a particular geographic coverage area 110 in which it supports communications with various UEs 115. Each base station 105 may provide communications coverage for the 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.

[0082] The geographic coverage area 110 of the base station 105 may be divided into sectors that constitute only a portion of the geographic coverage area 110, and each sector may be associated with a cell. For example, each base station 105 may provide communication coverage for a macrocell, a small cell, a hotspot, or other types of cells, or various combinations thereof. In some examples, the base station 105 may be mobile and therefore provide communication coverage for a mobile geographic coverage area 110. In some examples, different geographic coverage areas 110 associated with different technologies may overlap, and overlapping geographic coverage areas 110 associated with different technologies may be supported by the same base station 105 or different base stations 105. The wireless communication system 100 may include, for example, a heterogeneous LTE / LTE-A / LTE-A Pro or NR network, in which different types of base stations 105 provide coverage for various geographic coverage areas 110.

[0083] The term "cell" refers to a logical communication entity for communicating with base station 105 (e.g., on a carrier), and may be associated with an identifier to distinguish adjacent cells operating via the same or different carriers (e.g., physical cell identifier (PCID), virtual cell identifier (VCID)). 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), or others). In some cases, the term "cell" may refer to a portion of a geographic coverage area 110 (e.g., a sector) on which the logical entity operates.

[0084] Each UE 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be stationary 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 term, wherein "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.).

[0085] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated 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 person interacting with the program or application. Some UEs 115 may be designed to collect information or implement automated behavior of machines. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[0086] Some UEs 115 may be configured to employ a reduced power consumption mode of operation, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception but not simultaneous transmission and reception). In some examples, half-duplex communication may be performed with 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 operating over a limited bandwidth (e.g., in accordance with 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.

[0087] 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 UEs in a 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 be able to receive transmissions from the base station 105 for other reasons. In some cases, each 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 involving the base station 105.

[0088] 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 interfaces). The base stations 105 may communicate with each other directly (e.g., directly between the base stations 105) or indirectly (e.g., via the core network 130) on a backhaul link 134 (e.g., via X2, Xn, or other interfaces).

[0089] 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 of UEs 115 served by base stations 105 associated with the EPC. User IP packets may be delivered through 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 network operator IP services. Operator IP services may include access to the Internet, intranets, IP multimedia subsystems (IMS), or packet switched (PS) streaming services.

[0090] At least some network devices (such as base stations 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 each UE 115 through a number of other access network transport entities, which may be referred to as radio heads, smart radio heads, or transmission / reception 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 merged into a single network device (e.g., base station 105).

[0091] The wireless communication system 100 may operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. In general, the 300 MHz to 3 GHz region is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about 1 decimeter to 1 meter long. UHF waves may be blocked or redirected by buildings and environmental features. However, these waves may penetrate various structures sufficiently for macro cells to provide services to UEs 115 located indoors. Transmission of UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 km) compared to transmission using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.

[0092] The wireless communication system 100 may also operate in the Super High Frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, also known as the centimeter band. The SHF region includes frequency bands that may be opportunistically used by devices that can tolerate interference from other users, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band.

[0093] The wireless communication system 100 may also operate in the extremely high frequency (EHF) division of the spectrum (e.g., from 30 GHz to 300 GHz), which is also referred to as the millimeter band. 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 antenna of the corresponding device may be even smaller and more closely spaced than the UHF antenna. In some cases, this may facilitate the use of antenna arrays within the UE 115. However, the propagation of EHF transmissions may be subject to even greater atmospheric attenuation and shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency divisions, and the use of designated frequency bands across these frequency divisions may differ by country or regulatory agency.

[0094] In some cases, the wireless communication system 100 may utilize both licensed and unlicensed radio frequency spectrum bands. For example, the wireless communication system 100 may adopt license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology in an unlicensed band (such as a 5GHz ISM band). When operating in an unlicensed radio frequency spectrum band, wireless devices (such as base stations 105 and UE 115) may adopt a listen-before-talk (LBT) procedure to ensure that the frequency channel is clear before transmitting data. In some cases, operations in unlicensed bands can be based on carrier aggregation (CA) configuration in coordination with component carriers (CCs) operating in licensed bands (e.g., LAA). Operations in unlicensed spectrum may include downlink transmissions, uplink transmissions, peer-to-peer transmissions, or a combination of these. Duplexing in unlicensed spectrum may be based on frequency division duplexing (FDD), time division duplexing (TDD), or a combination of the two.

[0095] 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) communication, or beamforming. For example, the wireless communication system 100 may use a transmission scheme between a transmitting device (e.g., the base station 105) and a receiving device (e.g., the UE 115), wherein the transmitting device is equipped with multiple antennas and the receiving device is equipped with one or more antennas. MIMO communication 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. For example, the transmitting device may transmit multiple signals via different antennas or different antenna combinations. Similarly, the receiving device may receive multiple signals via different antennas or different antenna combinations. Each of these 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.

[0096] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a base station 105 or a UE 115) to shape or direct 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 may be achieved by combining signals communicated via antenna elements of an antenna array so that signals propagating at a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals communicated via antenna elements may include the transmitting device or the receiving device applying a particular amplitude and phase shift to the signal carried via each antenna element associated with the device. Adjustments associated with each antenna element may 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).

[0097] 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 transmitted multiple times by the base station 105 in different directions, which may include a signal being transmitted 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) a 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 transmitted 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 transmitted in different beam directions. For example, UE 115 may receive one or more signals transmitted by base station 105 in different directions, and UE 115 may report indications of the signals it received with the highest signal quality or other acceptable signal quality to base station 105. Although these techniques are described with reference to signals transmitted by base station 105 in one or more directions, UE 115 may use similar techniques for transmitting signals multiple times in different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or for transmitting signals in a single direction (e.g., for transmitting data to a recipient device).

[0098] A receiving device (e.g., UE 115, which may be an example of a mmW receiving device) may try multiple receive beams when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from base station 105. For example, the receiving device may try multiple receive directions by receiving via different antenna subarrays, processing received signals according to different antenna subarrays, receiving according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, or processing received signals according to different receive beamforming weight sets applied to signals received at multiple antenna elements of an 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). The single receive beam may be aligned on a beam direction determined at least in part based on listening according to different receive beam directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio, or other acceptable signal quality based at least in part on listening according to multiple beam directions).

[0099] 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 assembly, 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 having several rows and columns of antenna ports that the base station 105 may use to support beamforming for communications with a UE 115. Likewise, a UE 115 may have one or more antenna arrays that may support various MIMO or beamforming operations.

[0100] 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 of 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 packet segmentation and reorganization to communicate on the logical channel. The media access control (MAC) layer can perform priority handling and multiplex logical channels into transport channels. The MAC layer can also use hybrid automatic repeat request (HARQ) to provide retransmission of the MAC layer, thereby improving link efficiency. In the control plane, the radio resource control (RRC) protocol layer can provide the establishment, configuration and maintenance of the RRC connection of the radio bearer supporting user plane data between the UE 115 and the base station 105 or the core network 130. In the physical (PHY) layer, the transport channel can be mapped to the physical channel.

[0101] In some cases, UE 115 and base station 105 may support retransmission of data to increase the likelihood that the data is successfully received. HARQ feedback is a technique that increases the likelihood of correctly receiving data on communication link 125. HARQ may 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 of the MAC layer in poor radio conditions (e.g., signal-to-noise ratio conditions). In some cases, a wireless device may support simultaneous slot HARQ feedback, where the device may provide HARQ feedback in a specific time slot for data received in a previous symbol in the time slot. In other cases, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0102] The time interval in LTE or NR can be represented by a basic time unit (which may refer to a sampling period T, for example). 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 expressed as T f =307,200Ts . A radio frame may be identified by a system frame number (SFN) ranging from 0 to 1023. Each frame may include 10 subframes numbered from 0 to 9, and each subframe may have a duration of 1 ms. A subframe may be further divided into 2 time slots, each having a duration of 0.5 ms, and each time slot may contain 6 or 7 modulation codeword periods (e.g., depending on the length of the cyclic prefix added before each codeword period). Excluding the cyclic prefix, each codeword period may contain 2048 sampling periods. In some cases, a subframe may be the minimum scheduling unit of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In other cases, the minimum scheduling unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI) or in a selected component carrier using sTTI).

[0103] In some wireless communication systems, a time slot may be further divided into a plurality of mini-slots containing one or more symbols. In some instances, a symbol of a mini-slot or a mini-slot may be the minimum scheduling unit. For example, each symbol may vary in duration depending on the subcarrier spacing or the operating frequency band. Further, some wireless communication systems may implement time slot aggregation, wherein a plurality of time slots or mini-slots are aggregated together and used for communication between UE 115 and base station 105.

[0104] The term "carrier" refers to a set of radio frequency 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 frequency 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 for discovery 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 include multiple subcarriers (e.g., using a multi-carrier modulation (MCM) technique such as OFDM or DFT-s-OFDM).

[0105] 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 according to TTIs or time slots, each of which may include user data and control information or signaling to support decoding of the user data. A carrier may also include dedicated acquisition signaling (e.g., synchronization signals or system information, etc.) and control signaling to coordinate carrier operations. In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling or control signaling to coordinate the operations of other carriers.

[0106] 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, for example, using a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. In some examples, control information transmitted in a physical control channel may be distributed in a cascaded manner between different control regions (e.g., between a common control region or a common search space and one or more UE-specific control regions or UE-specific search spaces).

[0107] A carrier may be associated with a particular bandwidth of the radio frequency spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of several predetermined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). In some examples, each served UE 115 may be configured to operate on part or all of the carrier bandwidth. In other examples, some UEs 115 may 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).

[0108] In a system using MCM technology, a resource element may include a symbol period (e.g., the duration of a modulation symbol) and a subcarrier, where the symbol period and the subcarrier spacing are inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme). Thus, the more resource elements received by UE 115 and the higher the order of the modulation scheme, the higher the data rate of UE 115 can be. In a MIMO system, wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and space resources (e.g., space layers), and the use of multiple space layers may further increase the data rate of communication with UE 115.

[0109] A device (e.g., base station 105 or UE 115) of wireless communication system 100 may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configurable to support communication on one carrier bandwidth in a set of carrier bandwidths. In some examples, wireless communication system 100 may include base stations 105 and / or UEs 115 that may support simultaneous communication via carriers associated with more than one different carrier bandwidths.

[0110] 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 CA or multi-carrier operation. The UE 115 may be configured with multiple downlink CCs and one or more uplink CCs according to a carrier aggregation configuration. Carrier aggregation may be used with both FDD and TDD component carriers.

[0111] In some cases, the wireless communication system 100 may utilize an enhanced component carrier (eCC). An eCC may be characterized by one or more features 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 may 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 may also be configured for use in an unlicensed spectrum or a shared spectrum (e.g., where more than one operator is allowed to use the spectrum). An eCC characterized by a wide carrier bandwidth may include one or more segments that may be utilized by a UE 115 that is not capable of monitoring the entire carrier bandwidth or is otherwise configured to use a limited carrier bandwidth (e.g., to save power).

[0112] 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., based on a frequency channel or carrier bandwidth of 20, 40, 60, 80 MHz, etc.) with a reduced symbol duration (e.g., 16.67 microseconds). A TTI in an eCC may include one or more symbol periods. In some cases, the TTI duration (i.e., the number of symbol periods in a TTI) may be variable.

[0113] Wireless communication systems (such as NR systems) can utilize any combination of licensed, shared, and unlicensed spectrum bands, etc. The flexibility of eCC symbol duration and subcarrier spacing can allow for the use of eCC across multiple spectrums. In some examples, NR shared spectrum can improve spectrum utilization and spectrum efficiency, particularly through dynamic vertical (e.g., across frequency domain) and horizontal (e.g., across time domain) sharing of resources.

[0114] Some wireless communication systems 100 (e.g., mmW systems) may support UEs 115 operating in C-DRX mode. In C-DRX mode, UE 115 may transition between an active state (e.g., active mode) for data transmission and reception and a sleep state (e.g., inactive or low power mode) for power saving. UE 115 may determine whether data is available by monitoring a control channel (such as PDCCH). PDCCH may carry or otherwise convey an indication that a base station 105 has data ready to be transmitted to UE 115 or is scheduling UE 115 for data transmission. In some cases, in order to reduce the frequency of control channel monitoring, UE 115 may use a low complexity receiver to monitor a wake-up signal when in a low power mode. If UE 115 detects a wake-up signal transmitted by base station 105, UE 115 may transition to a higher power mode in order to monitor the control channel for scheduling information. However, if the UE 115 does not detect a wake-up signal transmitted by the base station, the UE 115 may skip the control channel monitoring opportunity and instead return to the deep sleep mode, thereby improving power conservation at the UE 115 .

[0115] In some cases, the base station 105 may serve a large number of UEs 115 within a cell. In order to efficiently use the wake-up signal, the base station 105 may distinguish the wake-up signal intended for each UE 115 or a group of UEs 115 based on the wake-up signal resource configuration. For example, each UE 115 may be configured with a specific wake-up signal resource configuration, wherein the wake-up signal resource configuration indicates how the UE 115 monitors for wake-up signals, decodes wake-up signals, or both. If a UE 115 detects a wake-up signal transmitted according to the wake-up signal resource configuration for the UE 115, the UE 115 may initiate a wake-up procedure according to the wake-up signal. However, if the UE 115 detects a wake-up signal transmitted according to a different wake-up signal resource configuration, the UE 115 may determine that the wake-up signal is intended for a different UE 115 or a group of UEs 115, and may not perform a wake-up procedure.

[0116] The wake-up signal resource configuration may indicate several resource configuration parameters. These resource configuration parameters may include time resource information (e.g., the start symbol index and the duration of the monitoring window), frequency resource information for the monitoring window, decoding parameter information (e.g., scrambling sequence, DCI format, RNTI, decoding assumptions, or some combination of these parameters for successfully decoding the wake-up signal), beam sweep information (e.g., the number of beams used to receive the wake-up signal, beam repetition factor, beam pattern, etc.), or some combination of these parameters or other related parameters. If the UE 115 receives the wake-up signal in the monitoring opportunity defined by the wake-up signal resource configuration and successfully decodes the wake-up signal according to the decoding parameters defined by the wake-up signal resource configuration, the UE 115 may determine that the wake-up signal is intended for the UE 115. Accordingly, the UE 115 may perform a wake-up procedure to transition to a higher power mode and monitor scheduling information. In the higher power mode (e.g., active power mode), the UE 115 may operate according to a configuration different from the wake-up signal resource configuration. By using these wake-up signal resource configurations to differentiate wake-up signals to different UEs 115 , the wireless communication system 100 may support improved power conservation at the UE 115 .

[0117] Figure 2 An example of a wireless communication system 200 supporting wake-up signaling resource opportunities according to various aspects of the present disclosure is illustrated. The wireless communication system 200 may be an example of the wireless communication system 100 and may include a base station 105-a, a UE 115-a, and a UE 115-b, which may be referenced to Figure 1 Examples of corresponding wireless devices described. Base station 105-a can provide network coverage for UE 115 within geographic coverage area 110-a. In some cases, UE 115 can support C-DRX operation with wake-up signal 210 to obtain improved power efficiency. For example, UE 115 can operate in a low power mode until signaled via wake-up signal 210 to transition to a higher power mode to support data transmission and reception. These wake-up signals 210 can be examples of reference signal type signals or PDCCH type signals. UE 115 (e.g., UE 115-a and UE 115-b) can distinguish between wake-up signals 210 transmitted by base station 105-a based on the type of wake-up signal 210, based on different parameters or configurations.

[0118] In a wireless communication system 200 (e.g., a mmW system supporting beamforming), a base station 105-a may transmit a wake-up signal 210 using a beam sweeping procedure. For example, the base station 105-a may transmit the wake-up signal 210 on a downlink channel 205 (e.g., a downlink control channel) using a number of different downlink transmit beams 215. The base station 105-a may sweep N different transmit beams for transmitting the wake-up signaling to improve reception reliability at the UE 115. For example, when the UE 115 is in a low power mode (e.g., a sleep mode), the UE 115 may experience some degree of beam degradation, such as beam misalignment, beam blocking, etc. In order to reduce the probability that the UE 115 misses the wake-up signal 210 transmitted by the base station 105-a due to the beam degradation, the base station 105-a may use various beam directions, beam widths, or both for transmitting the wake-up signal 210 to the UE 115. If the UE 115 successfully receives one or more wake-up signals 210 transmitted in the beam sweeping procedure, the UE 115 may perform the wake-up procedure and transition to a higher power level to support data transmission and reception. The number N of downlink transmit beams, or the direction of the beams in the beam sweeping, may be dynamically determined by the base station 105-a. The UE 115 may attempt to receive the wake-up signal 210 using a number of downlink receive beams 220. For example, the UE 115-a may use the downlink receive beam 220-a to monitor for wake-up signaling, while the UE 115-b may use the downlink receive beam 220-b to monitor for wake-up signaling.

[0119] UE 115 may be configured to receive a wake-up signal 210 according to specific configuration parameters and a configuration framework. In some cases, UE 115 may be preconfigured for a specific configuration framework, which may be referred to as a wake-up signal resource configuration. In other cases, base station 105-a may transmit an indication of a configuration framework for UE 115 (e.g., a configuration indicator). In a first example, the configuration framework for UE 115 may be an example of a downlink control channel (e.g., PDCCH) resource configuration. For example, the downlink control channel resource configuration may include one or more control resource sets (CORESETs), one or more search spaces, one or more monitoring opportunities, or a combination thereof. In a second example, the configuration framework for UE 115 may be an example of a reference signal (e.g., a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a demodulation reference signal (DMRS), etc.) configuration.

[0120] Each wake-up signal 210 may be a UE-specific or group-specific wake-up signal 210. For example, the base station 105-a may transmit a UE-specific wake-up signal 210 to initiate a wake-up procedure at a specific UE 115. That is, each UE 115 may have a dedicated wake-up signal 210, a dedicated signaling opportunity, or both. This may result in large network overhead (e.g., for the base station 105-a to transmit the wake-up signal 210 for each UE 115 scheduled to wake up) but highly flexible and efficient wake-up signaling for improved UE power saving. The base station 105-a may transmit a wake-up signal 210-a on a downlink channel 205-a to wake up the UE 115-a, and transmit a wake-up signal 210-b on a downlink channel 205-b to wake up the UE 115-b. If UE 115 - b detects wake-up signal 210 - a , UE 115 - b may identify that wake-up signal 210 - a is intended for a different UE 115 and may not perform the wake-up procedure.

[0121] Alternatively, if both UE 115-a and UE 115-b are in the same UE group, base station 105-a may transmit a group-specific wake-up signal 210 to wake up these UEs 115. That is, each predefined or dynamically defined group of UEs 115 may share the same wake-up signal 210, signaling opportunity, or both. This may result in low network overhead, but one or more UEs 115 may wake up based on a group-specific wake-up signal 210, even if the wake-up signal 210 is intended for another UE 115 in the same group. Waking up a UE 115 based on a group-specific wake-up signal 210 even if there is no data to transmit or receive may incur a power penalty.

[0122] To support a large number of UEs 115 within a cell (e.g., geographic coverage area 110-a), UEs 115 or groups of UEs may share available resources for monitoring wake-up signals 210. Base station 105-a may multiplex wake-up signals 210 such that available resources are efficiently used to support wake-up procedures for multiple UEs 115 with minimal power penalty. That is, by configuring UEs 115 with different resources for wake-up opportunities, base station 105-a may initiate wake-up procedures with different UEs 115 during small time windows without having to wake up other UEs 115 or groups of UEs 115.

[0123] Figure 3 An example of a UE operation timeline 300 supporting wake-up signaling resource opportunities according to various aspects of the present disclosure is illustrated. The UE operation timeline 300 may correspond to the timeline of FIG. Figure 1 and 2100 or 200. The UE 115 may utilize C-DRX operation to achieve power savings during periods of inactive traffic based on the capabilities or configuration of the UE 115. In some cases, the UE operation schedule 300 corresponds to UE operation in a legacy wireless communication system. To further save power in the wireless communication system 100 or 200, the UE 115 may additionally support a wake-up signal to trigger a ramp-up power for the UE "on" duration.

[0124] UE 115 can operate in several different power modes to support transmission and reception of data while achieving power conservation. For example, in the active duration 305-a, UE 115 can operate in a high power mode or a standard power mode (e.g., compared to a low power mode or a sleep mode of UE 115). During the active duration 305-a, UE 115 can receive signals during any number of reception durations 310, and can transmit signals during any number of transmission durations 315. For example, UE 115 can use a receiver (e.g., a full power or standard receiver) to receive downlink data from base station 105, transmit uplink data to base station 105, participate in D2D communication, or perform any combination of these operations. UE 115 can remain in a high power or standard power mode during an inactive period 320 after the active duration 305-a. During this inactive period, UE 115 may not detect any PDCCH signaling. UE 115 may initiate an inactivity timer at the beginning of the inactive period 320 (i.e., the end of the active duration 305-a). If UE 115 receives an additional signal (e.g., a PDCCH signal) or transmits an additional signal before the inactivity timer expires, UE 115 may reenter the additional active duration 305 and may reset the inactivity timer to restart at the end of the additional active duration 305. Otherwise, if the inactivity timer expires at 325, UE 115 may ramp down its power and enter a low power mode or sleep mode (e.g., a UE "off" duration). During the off duration, UE 115 may not transmit or receive signals due to the current UE power level. In this way, during periods of traffic inactivity, UE 115 may switch to C-DRX operation to achieve significant power savings.

[0125] Based on the configured C-DRX cycle, UE 115 can periodically or aperiodically wake up from low power mode to enter the open duration. During the open duration, UE 115 can monitor PDCCH to find any signaling (e.g., DCI message, grant, etc.) transmitted to UE 115. If UE 115 does not detect any PDCCH signaling for UE 115, UE 115 can return to the closed duration (i.e., return to sleep) in the remaining time of the C-DRX cycle after the open duration 330 in which no PDCCH is detected. UE 115 can then wake up in the next open duration and repeat PDCCH monitoring. The time length between each open duration can remain the same, or it can be changed based on one or more timers. For example, UE 115 can initially wake up from the closed mode at regular intervals defined by a short C-DRX cycle 335. However, upon expiration of the short C-DRX timer at 340 (e.g., where the short C-DRX timer may be activated at the end of the inactivity period 320), the UE 115 may switch from the short C-DRX cycle 335 to the long C-DRX cycle 345 to further save power. During the long C-DRX cycle 345, the UE 115 may periodically wake up for an on duration, wherein the time interval between the on durations of the long C-DRX cycle 345 is longer than the time interval between the on durations during the short C-DRX cycle 335. In some cases, the UE 115 may support additional C-DRX cycle lengths and corresponding timers.

[0126] If during the on duration, the UE 115 detects a PDCCH signal for the UE 115, the UE 115 may perform a wake-up procedure and may terminate the C-DRX mode (e.g., short C-DRX mode or long C-DRX mode). For example, the UE 115 may enter the active duration 305-b based on the on duration of detecting the PDCCH 350. In some cases, the PDCCH signal may schedule data for the UE 115, and the UE 115 may operate according to a number of reception durations 310, transmission durations 315, or both during the active duration 305-b according to the data scheduling. The UE 115 may remain in a high power or standard power mode for data transmission and reception during the active duration 305-b.

[0127] In some cases, the UE operation timeline 300 can be based on several configuration parameters for the UE 115. These configuration parameters may include an inactivity timer (e.g., the length of the inactivity period 320 after which the UE 115 is powered off), a short DRX timer (e.g., the length of the time to operate according to the short C-DRX cycle 335 before switching to the long C-DRX cycle 345), a short DRX cycle (e.g., the length of the first periodic short C-DRX cycle 335 that defines the on duration), a long DRX cycle (e.g., the length of the second periodic long C-DRX cycle 345 that defines the on duration), or any combination of these or other related parameters for DRX operation. In some cases, the UE 115 can be pre-configured with these configuration parameters. In other cases, the base station 105 can configure the UE 115 with the configuration parameters. Additionally, the durations, time periods, and cycles described herein can span any length of time (e.g., a number of symbols, slots, subframes, frames, etc.) based on the UE or base station configuration.

[0128] To further improve power savings at UE 115, UE 115 may implement a wake-up signal in conjunction with C-DRX operation. Using a low-power receiver, UE 115 may monitor for a wake-up signal indicating subsequent data scheduling. In order to handle a large number of UEs operating within a wireless communication system, these UEs may be configured with specific wake-up signaling resource opportunities and parameters. Using these parameters, UE 115 may identify whether the wake-up signal is intended for the UE 115, and may not wake up based on a wake-up signal intended for other UEs 115. In this way, if UE 115 is not explicitly instructed to wake up by base station 105, UE 115 may further achieve power savings by skipping the turn-on duration.

[0129] Figure 4 1 illustrates an example of a power level timeline 400 for a UE 115 supporting a wake-up signaling resource opportunity in accordance with aspects of the present disclosure. The power level timeline 400 may correspond to a UE 115 (such as, for example, referring to Figures 1 to 3 115) for different operating modes. The UE 115 may implement extended sleep functionality (e.g., as described with Figure 3 300 ) to support additional power savings. By supporting a wake-up procedure based on wake-up signaling that can be received at a lower power level than the PDCCH signaling (e.g., using a receiver with lower power than the receiver used to receive the PDCCH signaling), the UE 115 can efficiently determine whether to wake up for data and control channel processing 445. Figure 4As illustrated, the height of each bar may indicate the relative power level at which the UE 115 performs the corresponding operation, with higher bars indicating higher power levels. For example, wake-up signal reception 405 may correspond to a slightly higher power level than deep sleep 410 mode, but a lower power level than only PDCCH reception 440 or data and control channel processing 445.

[0130] UE 115 may turn on a wake-up subsystem for wake-up signal decoding while in low power mode. The wake-up subsystem may be an example of a low complexity receiver (such as a simple correlator). In this way, the wake-up subsystem may detect the wake-up signal using lower power than a receiver that performs PDCCH decoding in active mode (i.e., a standard or "full power" receiver). In some cases, the wake-up signal may be a special type of waveform, such as a frequency modulation, a preamble, a reference signal, etc. based on on-off keying (OOK). UE 115 may perform wake-up signal reception 405 before C-DRX turn-on duration 420. The pre-wake-up offset 415 may define a buffer period between wake-up signal reception 405 and turn-on duration 420 (e.g., for UE 115 to process any received wake-up signals and perform a power ramp-up procedure 435). If the UE 115 does not detect a wake-up signal during the wake-up signal reception 405 (e.g., if there is no downlink grant transmitted for the UE 115 at the wake-up signal reception 405-a during the pre-wake-up offset 415-a), the UE 115 can skip the turn-on duration 420 (e.g., the turn-on duration 420-a) and instead return to the deep sleep 410 mode until the next wake-up signal reception 415 opportunity. This wake-up signal reception 405 supporting an extended deep sleep 410 duration can save power at the UE 115 by reducing the amount of PDCCH monitoring.

[0131] In some cases, the UE 115 may detect a wake-up signal during wake-up signal reception. Based on this wake-up signal detection 425, the UE 115 may perform a power ramp-up procedure 435 (e.g., during the pre-wake-up offset 415-b). This power ramp-up procedure 435 may transition the UE 115 from a first power level (e.g., a power level associated with the deep sleep 410 mode) to a second power level (e.g., a power level associated with the PDCCH-only reception 440 mode). The UE 115 may monitor a grant 430 in the PDCCH-only reception 440 mode during the on-duration 420-b. This grant may be an example of a PDCCH grant scheduling data transmission or reception for the UE 115, and the grant may be indicated by the detected wake-up signal. For example, the base station 105 may transmit a wake-up signal to the UE 115 to indicate that the base station 105 is scheduled to transmit a PDCCH grant to the UE 115 during the next on-duration 420-b. The UE 115 may use the full modem for PDCCH reception and decoding instead of the wake-up subsystem. For example, the UE 115 may wake up within the on-duration 420-b and may use the full modem to monitor the PDCCH grant 430 at a power level greater than the power level used for wake-up signal reception 405. Based on the received PDCCH grant 430, the UE 115 may determine a schedule for performing data and control channel processing 445, which may be performed at a power level different from that of the PDCCH-only reception 440. After the data and control channel processing 445, the UE 115 may remain in the active mode and monitor any further PDCCH signals. If the UE 115 does not receive a further PDCCH grant before the inactivity timer expires (e.g., the UE 115 is inactive within a specific threshold duration 450), the UE 115 may perform a power ramp-down procedure 455 to return to the deep sleep 410. The UE 115 may then periodically or aperiodically check for wake-up signals according to the DRX cycle 460. For example, the wake-up signal reception 405 may occur near the end of the DRX cycle 460 such that the UE 115 may wake up within the next DRX cycle 460 if the wake-up signal is received.

[0132] UE 115 may be configured with specific wake-up signaling resource timing and parameters. Using these parameters, UE 115 can identify whether the wake-up signal is for the UE 115, and can not wake up based on the wake-up signal intended for other UE 115. The base station 105 that transmits the wake-up signal can use these configuration parameters to distinguish between UE 115 or UE 115 groups. In this way, the base station 105 can use different wake-up configurations to wake up a large number of UEs 115 in the same time window (e.g., the same wake-up signal reception 405 period), thereby supporting a large amount of data traffic in the system. In addition, different UE wake-up signaling configurations allow UE 115 to remain dormant even when a wake-up signal for other UEs 115 (e.g., a wake-up signal transmitted according to other configurations) is detected. In this way, even in a system with a high level of data traffic, UE 115 can achieve significant power savings by remaining in deep sleep 410 mode until specifically instructed to wake up by the base station 105.

[0133] Figure 5 An example of a wake-up procedure timeline 500 for a wireless communication system supporting wake-up signaling resource opportunities according to aspects of the present disclosure is illustrated. The wake-up procedure timeline 500 may correspond to wake-up signaling between a base station 105-b and a UE 115-c, which may be referenced to Figures 1 to 4 Examples of corresponding devices described. The base station 105-b and the UE 115-c can operate within a wireless communication system that supports beamforming, such as a mmW system. In some cases, the UE 115-c can use a low-power receiver to detect a wake-up signal transmitted by the base station 105-b. Based on whether the wake-up signal is detected, the UE 115-c can return to a lower power mode (i.e., return to sleep) or can transition to a higher power mode (i.e., wake up) to receive and / or transmit data.

[0134] The C-DRX timeline 505 illustrates operations performed by the UE 115-c. For example, during the first C-DRX on duration 510-a corresponding to the first C-DRX cycle 515-a, the UE 115-c may receive data from the base station 105-b, transmit data to the base station 105-b, perform other communication operations in an active mode, or any combination of these operations. After the first C-DRX on duration 510-a, the UE 115-c may enter a low power mode (e.g., based on an inactivity timer). However, according to the C-DRX cycle 515 schedule, the UE 115-c may periodically or non-periodically pre-wake up for wake-up signal detection 520-a. In some cases, the pre-wake-up procedure may involve the UE 115-c transitioning to a power level higher than the sleep mode, but lower than the active mode to monitor for a wake-up signal from the base station 105-b.

[0135] In a first example, the base station 105-b may not have data to transmit to or receive from the UE 115-c. In this example, at 525, the base station 105-b may not transmit a wake-up signal to the UE 115-c. In some cases, the base station 105-b may instead transmit one or more wake-up signals to other UEs 115 served by the base station 105-b. The UE 115-c may monitor for wake-up signals using a set of downlink receive beams 530-a. If the UE 115-c does not detect or otherwise receive a wake-up signal intended for the UE 115-c on any downlink receive beam 530-a, the UE 115-c may skip the C-DRX on duration at 535 within the C-DRX cycle 515-b and may instead return to a low power mode (i.e., return to sleep). In this way, the UE 115 - c may reduce its power consumption by not entering the C-DRX on duration 510 when there is no data scheduled for reception or transmission.

[0136] In a second example, the base station 105-b may identify data to be transmitted to or received from the UE 115-c. In this example, at 540, the base station 105-b may transmit a wake-up signal to the UE 115-c using a beam sweeping procedure (e.g., using several downlink transmit beams to transmit the wake-up signal). The UE 115-c may pre-wake up during the C-DRX cycle 515-b for wake-up signal detection 520-b, and may attempt to detect the wake-up signal using a set of downlink receive beams 530-b, which may be the same as or different from the set of downlink receive beams 530-a. If the UE 115-c detects a wake-up signal on any of these downlink receive beams 530-b, the UE 115-c may perform a full wake-up procedure to transmit or receive scheduled data in the C-DRX on duration 510-b.

[0137] Downlink transmit beams, downlink receive beams, or both may be configured for improved detection at UE 115-c. For example, base station 105-b may use a downlink transmit beam that includes N Tx A set of beams (e.g., from up to 64 synchronization signal block (SSB) beams) is used for wake-up signal transmission, and UE 115-c may use a set of N beams including Rx A set of beams (e.g., from up to 64 SSB beams) is used for wake-up signal reception. The number of beams, the direction of the beams, or both may be preconfigured for each wireless device, or may be configured based on a configuration message or a configuration function. For example, the configuration function for the beam may be based on link quality, UE mobility, one or more UE capabilities, C-DRX cycle 515 length, or some combination of these or other relevant parameters for wake-up signal reception. In some cases, the number and direction of downlink transmit beams, downlink receive beams, or both may be determined by the base station 105-b for each UE 115 or a group of UEs 115. The base station 105-b may use the determined number and direction of downlink transmit beams for a wake-up signal beam sweeping procedure. Additionally or alternatively, the base station 105-b may transmit a configuration message to the UE 115-c to indicate the determined number and direction of downlink receive beams for wake-up signal reception. In some cases, the UE 115 - c may not maintain beam information during the off duration and may be preconfigured with a default downlink receive beam to use during pre-wake-up 520 for wake-up signal detection.

[0138] In some cases, UE 115-c may be configured with other wake-up signal reception parameters. For example, these parameters may include values ​​that define a pre-wake-up 520 time period for wake-up signal detection (such as the starting code element of the time period, the number of code elements corresponding to the duration of the time period, or other time resources). In other cases, these parameters may include decoding information for UE 115-c, such as a scrambling sequence, a DCI format, an RNTI value, a decoding assumption, or some combination of these parameters. In some cases, the parameters indicated to UE 115c may be based on the format of the wake-up signal. For example, a PDCCH-type wake-up signal and a reference signal-type wake-up signal may correspond to different parameter sets. In some cases, base station 115-b may configure UE 115-c with wake-up signal reception parameters. UE115-c may detect a wake-up signal intended for UE 115-c based on the wake-up signal monitoring configuration.

[0139] Figure 6 A first example of a configuration for a wake-up signal resource 600 for supporting a wake-up signaling resource opportunity in accordance with various aspects of the present disclosure is illustrated. The configuration for the wake-up signal resource 600 may correspond to a downlink control channel resource configuration, such as a PDCCH-type wake-up signal configuration. The base station 105 may use the configuration for the wake-up signal resource 600 to distinguish between wake-up signals between UEs 115 or groups of UEs 115. The base station 105 and these UEs 115 may be referenced Figures 1 to 5 Examples of corresponding wireless devices are described. While the configuration for wake-up signal resources 600 as illustrated shows one possible wake-up signal resource configuration, many other configurations are possible using any of the techniques described herein.

[0140] A UE 115 within the wireless communication system may monitor for wake-up signals in one or more wake-up signaling resource opportunities according to the configuration of the UE 115. For example, the base station 105 may configure the UE 115 with a wake-up signal resource configuration set. In some cases, the UE 115 may store the wake-up signal resource configuration set in a lookup table in a memory. Subsequently, the base station 105 may transmit a configuration indicator to the UE 115, which indicates a specific wake-up signal resource configuration for the UE 115 to monitor and receive wake-up signals. In another example, the base station 105 may store the wake-up signal resource configuration set in a memory, and may transmit an indication of one of the configurations to the UE 115.

[0141] Each wake-up signal resource configuration may include a set of configuration parameters. These configuration parameters may include time resources, frequency resources, DCI formats, scrambling sequences, RNTIs, or any combination of these parameters or other related configuration parameters for distinguishing wake-up signals. Configuration parameters indicating time resources, frequency resources, or both may indicate to UE 115 how to monitor wake-up signals to be transmitted to UE 115. Configuration parameters indicating DCI formats, scrambling sequences, or RNTIs may indicate to UE 115 how to decode wake-up signals to be transmitted to UE 115. For example, if UE 115 successfully decodes the wake-up signal according to the configured DCI format (e.g., if the decoded wake-up signal passes an error detection check (EDC), such as a CRC), UE 115 may determine that the wake-up signal is intended for UE 115. Similarly, if the UE 115 performs descrambling processing on the received wake-up signal according to the indicated scrambling sequence, the indicated RNTI, or both, and successfully decodes the wake-up signal based on the descrambling processing, the UE 115 can initiate a wake-up procedure using the received wake-up signal.

[0142] In one specific example, the base station 105 may store a wake-up signal resource configuration lookup table including time resources for different UEs 115 or sets of UEs 115:

[0143] UE Start code element Number of PDCCH symbols 1 0 2 2 2 3 3 5 3 4 9 1 5 11 2

[0144] Table 1: Example of a wake-up signal resource configuration lookup table

[0145] The wake-up signal resource configuration lookup table may support multiplexing of UE 115 within a wake-up window of a time slot, wherein the table indicates a starting symbol index 610 and a number of symbols that each UE 115 or group of UEs 115 may monitor for a wake-up signal transmission. For example, if the base station 105 configures the UE 115 with resources configured for UE 1 (or UE group 1) as defined in Table 1, the UE 115 may be configured within a TTI or sTTI (e.g., time slot 605, where time slot 605 may correspond to the time slot 605 as described in reference to Table 1). Figure 4 and 5The base station 105 may monitor the wake-up signal during symbol indexes 0 and 1 of the wake-up signal reception period or pre-wake-up period (described as a wake-up signal reception period or pre-wake-up period) for wake-up signal detection using a low-power receiver. Similarly, a UE 115 configured for a dedicated wake-up signal opportunity defined for UE 2 may monitor the wake-up signal during symbol indexes 2, 3, and 4 of the time slot 605, a UE 115 configured for a dedicated wake-up signal opportunity for UE 3 may monitor during symbol indexes 5, 6, and 7, a UE 115 configured for a dedicated wake-up signal opportunity for UE 4 may monitor during symbol index 9, and a UE 115 configured for a dedicated wake-up signal opportunity for UE 5 may monitor during symbol indexes 11 and 12 according to the stored lookup table. In this way, the base station 105 may transmit a wake-up signal to any of five different UEs 115 or groups of UEs 115 within the same time slot 605, and each UE 115 may detect whether one of the wake-up signals initiates a wake-up procedure for the UE 115. Additionally or alternatively, UE 115 may be configured with multiple dedicated wake-up signal opportunities. For example, UE 115 may be configured for dedicated wake-up signal opportunities defined for UEs 1 and 3, where the UE 115 may monitor for wake-up transmissions during a first monitoring opportunity spanning symbol indices 0 to 1 and a second monitoring opportunity spanning symbol indices 5 to 7.

[0146] In some cases, the UE 115 may be configured with time and / or frequency resource configuration parameters for wake-up signal monitoring. For example, the frequency resource configuration parameters may specify a CORESET configuration (e.g., one or more CORESETs for a particular BWP) for the UE 115 to perform wake-up signal detection. Additionally or alternatively, the time resource configuration parameters may specify a search space configuration (e.g., a time slot 610 periodicity and an offset from a certain reference time in a TTI for one or more search spaces) and one or more monitoring opportunities within the time slot 610. The UE 115 may activate a low power receiver during the time specified by the configuration and monitor for wake-up signals on the frequency specified by the configuration.

[0147] In one example, two UEs 115 or groups of UEs 115 may share the same time and frequency resources for wake-up signal monitoring (e.g., according to the configuration of the wake-up signal resources). In this example, the wake-up signals transmitted by the base station 105 for different UEs 115 or groups of UEs 115 may use different DCI formats, scrambling sequences, RNTI values, or some combination of these parameters to distinguish the wake-up signals, so that each UE 115 or group of UEs 115 may successfully identify whether the detected wake-up signal is intended for the UE 115 or group of UEs 115. For example, the UE 115 may decode the received wake-up signal using the DCI format, scrambling sequence, RNTI value, or some combination of these parameters configured for the UE 115. If the decoding process is successful, the UE 115 may determine that the received wake-up signal is intended for the UE 115, and the UE 115 may initiate a wake-up procedure. If the decoding process using the configured decoding parameters is unsuccessful, the UE 115 may determine that the received wake-up signal is intended for a different UE 115 or group of UEs 115 and may return to sleep mode.

[0148] When UE 115 detects a wake-up signal transmitted according to a wake-up resource configuration for UE 115, UE 115 may initiate a wake-up procedure (e.g., transition from a low power mode to a higher power mode to support PDCCH reception and data communication). The higher power mode may correspond to an active duration of UE 115. UE 115 may operate according to different configurations for pre-wake-up and post-wake-up. For example, UE 115 may monitor and receive PDCCH-type wake-up signals according to a first configuration of wake-up signaling resources (e.g., a first search space configuration for monitoring downlink control channels). However, after UE 115 wakes up (i.e., during the active duration), UE 115 may monitor and receive PDCCH transmissions that schedule UE 115 for data communication according to a second configuration (e.g., a different PDCCH configuration, such as a second search space configuration for monitoring downlink control channels). In some cases, the second configuration may correspond to a control channel resource configuration associated with a serving cell configuration (e.g., ServingCellConfig) for UE 115. For example, UE 115 may be configured to receive a PDCCH type wake-up signal within any symbol index 610 of slot 605 based on the configuration for wake-up signal resources 600, while UE 115 may be restricted to receiving PDCCH scheduling within the first three symbols of a slot based on the active mode configuration of UE 115.

[0149] Figure 7A second example of a configuration of a wake-up signal resource 700 for supporting a wake-up signaling resource opportunity in accordance with various aspects of the present disclosure is illustrated. The configuration for the wake-up signal resource 700 may correspond to a reference signal configuration. The base station 105 may use the configuration for the wake-up signal resource 700 to distinguish between wake-up signals between UEs 115 or groups of UEs 115. The base station 105 and these UEs 115 may be reference signals. Figures 1 to 6 Examples of corresponding wireless devices are described. While the configuration for wake-up signal resources 700 as illustrated shows one possible wake-up signal resource configuration, many other configurations are possible using any of the techniques described herein.

[0150] A UE 115 within a wireless communication system (e.g., a mmW system) may monitor a wake-up signal in one or more wake-up signaling resource opportunities according to the configuration of the UE 115. For example, the base station 105 may configure the UE 115 with a wake-up signal resource configuration set. In some cases, the UE 115 may store a wake-up signal resource configuration set in a lookup table in a memory. Subsequently, the base station 105 may transmit a configuration indicator to the UE 115, which indicates a specific wake-up signal resource configuration for the UE 115 to monitor and receive the wake-up signal. In another example, the base station 105 may store a wake-up signal resource configuration set in a memory, and may transmit an indication of one of the configurations to the UE 115. Each wake-up signal resource configuration may include a set of configuration parameters. These configuration parameters may include time resources, frequency resources, the number of beams used for a beam sweeping procedure, the number of repetitions per beam used for a beam sweeping procedure, a beam direction, one or more beam patterns, a scrambling sequence, a decoding assumption, or any combination of these parameters or other related configuration parameters for distinguishing a reference signal type wake-up signal.

[0151] In some cases, UE 115 may be configured with time and / or frequency resource configuration parameters for wake-up signal monitoring. The resource configuration may be an example of a reference signal resource configuration (e.g., similar to a CSI-RS configuration) for receiving a reference signal type wake-up signal. The reference signal resource configuration may be applied to monitor reference signals for initiating a wake-up procedure, but may not be applied to monitor reference signals after UE 115 wakes up (i.e., operating in active mode). For example, when monitoring wake-up signals in low power mode, UE 115 may monitor according to the configuration for wake-up signal resources 700. When monitoring reference signals (e.g., CSI-RS, TRS, DMRS, etc.) in high power mode (e.g., during an active duration), UE 115 may monitor according to a serving cell configuration for UE 115.

[0152] As illustrated, the base station 105 may configure four different UEs 115 or groups of UEs 115 with different configurations of wake-up signal resources. The base station 105 may multiplex these four UEs 115 or groups of UEs 115 within the same wake-up window spanning the same TTI (e.g., time slot 710) and bandwidth (e.g., resource blocks (RBs) 715). Each of the UEs 115 or groups of UEs 115 may be configured with a different number of beams 705, a different repetition factor of the beams 705, a different beam pattern, or some combination of these configuration parameters.

[0153] For example, the first UE 115 may be configured with four beams 705 (e.g., beams 705-a, 705-b, 705-c, and 705-d), where each beam 705 does not repeat in a beam sweeping procedure. These beams 705 may correspond to downlink transmit beams (wherein the UE 115 attempts to receive a wake-up signal according to the configured downlink transmit beam) or downlink receive beams used by the UE 115 for wake-up signal reception in the configured time and frequency resources. For example, the first UE 115 may be configured with four beams 705 within a TTI (e.g., time slot 710), where each beam has a repetition factor of 1 (e.g., each beam 705 is used in a single codeword of the TTI). Across time, a set of four beams 705 may be configured with a beam pattern of beam 705-a, followed by beam 705-b, followed by beam 705-d, and followed by beam 705-c. The same beam pattern may be repeated at multiple different frequencies within the set of RBs 715. The second UE 115 may be configured with the same number of beams 705, the same beam repetition, and the same beam pattern, but in different frequency resources. The third UE 115 may be configured with two beams 705 (e.g., beams 705-a and 705-d), where each of the two beams 705 is repeated once in the beam sweep procedure (e.g., beam 705-a and beam 705-d each have a repetition factor of 2, depending on the wake-up signal resource configuration). The fourth UE 115 may be configured with one beam 705-c, where beam 705-c is repeated so that the wake-up signal is transmitted on the beam 705-c across four symbols of the time slot 710 (e.g., beam 705-c may be configured with a repetition factor of 4).

[0154] In some cases, the UE 115 may determine to initiate a wake-up procedure based on receiving a wake-up signal on any configured beam 705 in the configured resources. For example, the UE 115 may be configured with a specific decoding hypothesis for successfully decoding a received wake-up signal according to the wake-up signal resource configuration for the UE 115. The decoding hypothesis may correspond to a beam pattern used to receive the wake-up signal from the base station 105. If the UE 115 receives the wake-up signal according to the configured beam pattern, the UE 115 may successfully decode the wake-up signal using the configured decoding hypothesis, and may initiate a wake-up procedure accordingly. It should be understood that these UE 115 configurations are given as examples, and many other UE 115 configurations for reference signal type wake-up signal reception are possible using the techniques described herein.

[0155] Figure 8 An example of a process flow 800 for supporting wake-up signaling resource opportunities according to aspects of the present disclosure is illustrated. The process flow 800 may include a base station 105-c and a UE 115-d, which may be referenced Figures 1 to 7 Examples of corresponding devices described. UE 115-d can use wake-up signals to support C-DRX operation to achieve power savings. UE115-d can be configured (e.g., preconfigured or configured by base station 105-c) to receive wake-up signals in specific wake-up signal resources to efficiently utilize available resources in the system. The following alternative examples can be implemented, in which some of the steps are performed in a different order than described or not performed at all. In some cases, each step may include additional features not mentioned below, or further steps may be added.

[0156] At 805, the base station 105-c may transmit configuration signaling to the UE 115-d. The configuration signaling may configure the UE 115-d with a wake-up signal resource configuration set. Additionally or alternatively, the configuration signaling may configure the UE 115-d with a monitoring configuration when operating in an active mode. In some cases, the UE 115-d may generate a table based on the configuration signaling, and each index in the table may correspond to a corresponding configuration (e.g., a corresponding wake-up signal resource configuration). Each wake-up signal resource configuration may include a set with one or more configuration parameters. At 810, the base station 105-c may transmit a configuration indicator indicating a first wake-up signal resource configuration in the wake-up signal resource configuration set to the UE 115-d. For example, the UE 115-d may use the received configuration indicator to index the configured table. The UE 115-d may determine one or more resource parameters for monitoring the wake-up signal based on the indicated first wake-up signal resource configuration.

[0157] In some cases, the first wake-up signal resource configuration may be an example of a downlink control channel resource configuration (e.g., a PDCCH configuration). The first wake-up signal resource configuration may correspond to resource parameters indicating a start symbol within a TTI, a number of symbols within a TTI, a frequency resource (e.g., a CORESET), a time resource (e.g., a search space), a scrambling sequence, a DCI format, an RNTI value, or some combination of these parameters. In other cases, the first wake-up signal resource configuration may be an example of a reference signal configuration. The first wake-up signal resource configuration may indicate the number of different beams by which the wake-up signal is transmitted, a beam repetition factor for at least one beam, a beam pattern for at least one beam, beam patterns for different beam sets, decoding assumptions for decoding the wake-up signal, or some combination of these parameters.

[0158] At 815, the UE 115-d may operate according to a low power mode. For example, the UE 115-d may be "sleep" and may not transmit or receive data in the low power mode. The UE 115-d may periodically monitor the wake-up signal to identify whether the UE 115-d should wake up for data communication. For example, at 820, the UE 115-d may monitor the wake-up signal resource for a wake-up signal transmission based on the first wake-up signal resource configuration.

[0159] In some cases, the base station 105-c may not identify any data for communicating with the UE 115-d. Accordingly, during the configured wake-up signal monitoring opportunity, the base station 105-c may not transmit a wake-up signal to the UE 115-d. If the UE 115-d does not detect the wake-up signal, the UE 115-d may remain in a low power mode. However, in other cases, the base station 105-c may identify data for communicating with the UE 115-d. In these cases, the base station 105-c may transmit a wake-up signal to the UE 115-d at 825. The base station 105-d may transmit the wake-up signal using the wake-up signal resources that the UE 115-d is configured to monitor. The UE 115-d may detect the wake-up signal based on a monitoring procedure, and may identify that the wake-up signal is intended for the UE 115-d. Accordingly, at 830, the UE 115-d may initiate a wake-up procedure based on detecting the wake-up signal. In some examples, the wake-up signal can be an example of an OOK-based tone, a preamble, a reference signal, a PDCCH transmission, or some combination of these signals.

[0160] Based on the wake-up procedure, the UE 115-d may transition from a low power mode to a high power mode (e.g., "high" and "low" are relative to each other). In the high power mode during the on duration, at 835, the UE 115-d may monitor a control channel (e.g., a PDCCH) for scheduling grants. At 840, the base station 105-c may transmit a scheduling grant to the UE 115d on the PDCCH, wherein the grant schedules the UE 115-d for data transmission, data reception, or both during the active duration. At 845, the UE 115-d and the base station 105-c may communicate according to the scheduling grant.

[0161] In some cases, the UE 115-d may use an inactivity timer to determine when to return to the low power mode. For example, after the UE 115-d has ceased communicating with the base station 105-c, the UE 115-d may initiate the inactivity timer. If the timer expires before the UE 115-d is scheduled by the base station 105-c for any further transmissions (e.g., if the UE 115-d does not receive a grant from the base station 105-c within a defined amount of time), the UE 115-d may initiate a sleep procedure at 850 and return to the low power mode.

The configuration identifier 1115 may receive a configuration indicator indicating a first wake-up signal resource configuration in the wake-up signal resource configuration set.

In some cases, each decoding hypothesis in the set of decoding hypotheses corresponds to a different beam pattern of at least one beam by which a wake-up signal is transmitted during a transmission time interval.

[0189] In some cases, the first search space configuration includes at least one resource configuration parameter, and monitoring the downlink control channel is based on the at least one resource configuration parameter. For example, the at least one resource configuration parameter can be a starting symbol within a TTI, a number of symbols within a TTI, a frequency resource configuration parameter (e.g., a CORESET configuration parameter), a time resource configuration parameter (e.g., a search space configuration parameter or a control channel monitoring opportunity configuration parameter), a scrambling sequence, a DCI format, an RNTI, or a combination thereof, and monitoring the downlink control channel, decoding the wake-up signal transmission, or both can be based on any number of these parameters. In some examples, the first search space configuration can include multiple CORESETs in a BWP, multiple control channel monitoring opportunities within a TTI or search space, or both.
