Technical Field

[0004] Aspects of the present disclosure generally relate to wireless communication and relate to techniques and apparatuses for a wake-up signal monitoring window. Background Art

[0005] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single-Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / Advanced LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the Third Generation Partnership Project (3GPP).

[0006] A wireless communication network may include several base stations (BSs) capable of supporting communication of several user equipments (UEs). A user equipment (UE) may communicate with a base station (BS) via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmission reception point (TRP), New Radio (NR) BS, 5G Node B, and so on.

[0007] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments to communicate at the urban, national, regional, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhanced set of the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectral efficiency, reducing costs, improving services, utilizing new spectrums, and using Orthogonal Frequency Division Multiplexing with Cyclic Prefix (CP-OFDM) on the downlink (DL), CP-OFDM and / or SC-FDM (e.g., also referred to as Discrete Fourier Transform Spread OFDM (DFT-s-OFDM)) on the uplink (UL), and supporting beamforming, Multiple-Input Multiple-Output (MIMO) antenna technology, and carrier aggregation to better integrate with other open standards. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and the telecommunication standards that employ these technologies. SUMMARY OF THE INVENTION

[0008] In some aspects, a wireless communication method performed by a User Equipment (UE) includes: determining a monitoring window for monitoring a search space set for a Physical Downlink Control Channel (PDCCH) Wake-Up Signal (WUS), where the monitoring window is a part of the configured monitoring window for the search space set; and monitoring the search space set within the monitoring window for the PDCCH WUS.

[0023] The various aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently or in combination with any other aspect of the present disclosure. For example, any number of the aspects set forth herein may be used to implement an apparatus or practice a method. Additionally, the scope of the present disclosure is intended to cover such apparatus or methods practiced using other structures, functionality, or a combination of structures and functionality that supplement or are additional to the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be implemented by one or more elements of a claim.

[0024] Certain aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0025] It should be noted that although aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, aspects of the present disclosure may be applied in communication systems based on other generations (such as 5G and later generations, including NR technologies).

[0026] Figure 1FIG. 0 is a diagram illustrating a wireless network 100 in which aspects of the present disclosure may be practiced. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include several BSs 110 (shown as BS110a, BS110b, BS110c, and BS110d) and other network entities. A BS is an entity that communicates with user equipment (UE) and may also be referred to as a base station, NR BS, B node, gNB, 5G B node (NB), access point, transmission reception point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0027] A BS may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., with a radius of several kilometers) and may allow unrestricted access by UEs having a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs having a service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs associated with the femto cell (e.g., UEs in a closed subscriber group (CSG)). A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in Figure 1 FIG. 5, BS110a may be a macro BS for macro cell 102a, BS110b may be a pico BS for pico cell 102b, and BS110c may be a femto BS for femto cell 102c. A BS may support one or more (e.g., three) cells. The terms "eNB", "base station", "NR BS", "gNB", "TRP", "AP", "B node", "5G NB", and "cell" may be used interchangeably herein.

[0028] In some aspects, a cell may not have to be stationary, and the geographic area of a cell may move according to the location of a mobile BS. In some aspects, BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces, such as direct physical connections, virtual networks, and / or analogs using any suitable transport network.

[0029] The wireless network 100 may also include a relay station. A relay station is an entity that can receive transmissions of data from an upstream station (e.g., a BS or a UE) and send transmissions of the data to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that can relay transmissions for other UEs. Figure 1 In the example shown in , a relay base station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay base station may also be referred to as a relay BS, a relay station, a relay, or the like.

[0030] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0031] A network controller 130 may be coupled to a set of BSs and may provide coordination and control of these BSs. The network controller 130 may communicate with each BS via a backhaul. The BSs may also communicate with each other directly or indirectly, for example, via a wireless or wired backhaul.

[0032] UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout the wireless network 100, and each UE may be stationary or mobile. UEs may also be referred to as access terminals, terminals, mobile stations, subscriber units, stations, etc. A UE may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0033] Some UEs may be considered machine type communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide connectivity to a network (e.g., a wide area network such as the Internet or a cellular network) or provide connectivity to the network via a wired or wireless communication link, for example. Some UEs may be considered Internet of Things (IoT) devices, and / or may be implemented as narrowband IoT (NB-IoT) devices. Some UEs may be considered customer premise equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as processor components, memory components, etc.

[0034] Generally, any number of wireless networks may be deployed in a given geographical area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. The RAT may also be referred to as a radio technology, an air interface, etc. The frequency may also be referred to as a carrier, a frequency channel, etc. Each frequency may support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network may be deployed.

[0035] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., communicate with each other without using base station 110 as an intermediary). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, etc.), a mesh network, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0036] As indicated above, Figure 1 is provided as an example. Other examples may be different from the example regarding Figure 1 described.

[0037] Figure 2 A diagram of design 200 of base station 110 and UE 120 is shown, where base station 110 and UE 120 may be Figure 1One of the base stations and one of the UEs in []. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, where generally T≥1 and R≥1.

[0038] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCSs) for the UE at least in part based on the channel quality indicator (CQI) received from each UE, process (e.g., encode and modulate) the data for the UE at least in part based on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRSs)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols when applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from the modulators 232a to 232t may be transmitted via the T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be utilized to generate synchronization signals to convey additional information.

[0039] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols when applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The channel processor may determine the reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing.

[0040] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266 when applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, the uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 when applicable, and further processed by the receive processor 238 to obtain the decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0041] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component may perform one or more techniques associated with a wake-up signal (WUS) monitoring window, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component may perform or direct the operation of, for example, Figure 6 Process 600 and / or the operation of other processes as described herein. The memories 242 and 282 may store data and program code for the base station 110 and the UE 120, respectively. In some aspects, the memory 242 and / or the memory 282 may include: a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, when executed by one or more processors of the base station 110 and / or the UE 120, the one or more instructions may perform or direct the operation of, for example, Figure 6 Process 600 and / or the operation of other processes as described herein. The scheduler 246 may schedule the UE for data transmission on the downlink and / or uplink.

[0042] In some aspects, the UE 120 may include: means for determining a monitoring window for monitoring a search space set for a physical downlink control channel (PDCCH) WUS, where the monitoring window is part of a configured monitoring window for the search space set; and means for monitoring the search space set for the PDCCH WUS within the monitoring window; and so on. In some aspects, such means may include one or more components of the UE 120 described in conjunction with Figure 2 Such as the controller / processor 280, the transmit processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252, the DEMOD 254, the MIMO detector 256, the receive processor 258, and so on.

[0043] As indicated above, Figure 2 is provided as an example. Other examples may be different from the examples described with respect to Figure 2 described.

[0044] Figure 3A Illustrates an example frame structure 300 for frequency division duplexing (FDD) in a telecommunication system (e.g., NR). The transmission timeline for each of the downlink and the uplink may be divided into radio frames (sometimes referred to as frames). Each radio frame may have a predetermined duration (e.g., 10 milliseconds (ms)), and may be divided into a set of Z (Z≥1) subframes (e.g., having indices 0 to Z-1). Each subframe may have a predetermined duration (e.g., 1 ms) and may include a set of time slots (e.g., in Figure 3AEach subframe shows 2m time slots, where m is a parameter design for transmission, such as 0, 1, 2, 3, 4, and so on). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., as shown in Figure 3A ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two time slots (e.g., when m = 1), the subframe may include 2L symbol periods, where the 2L symbol periods in each subframe may be assigned indices 0 to 2L–1. In some aspects, the scheduling unit for FDD may be frame-based, subframe-based, time slot-based, symbol-based, and so on.

[0045] Although some techniques are described herein in connection with frames, subframes, time slots, etc., these techniques may equivalently apply to other types of wireless communication structures, which may be referred to by terms other than "frame", "subframe", "time slot", etc. in 5G NR. In some aspects, a "wireless communication structure" may refer to a periodically time-bounded communication unit defined by a wireless communication standard and / or protocol. Additionally or alternatively, wireless communication structure configurations different from those shown in Figure 3A may be used.

[0046] In certain telecommunications (e.g., NR), a base station may transmit synchronization (SYNC) signals. For example, a base station may transmit a primary synchronization signal (PSS), a secondary synchronization signal (SSS), etc. on the downlink for each cell supported by the base station. The PSS and SSS may be used by a UE for cell search and capture. For example, the PSS may be used by the UE to determine symbol timing, while the SSS may be used by the UE to determine the physical cell identifier associated with the base station and frame timing. The base station may also transmit a physical broadcast channel (PBCH). The PBCH may carry some system information, such as the system information that supports the initial access of the UE.

[0047] In some aspects, a base station may transmit the PSS, SSS, and / or PBCH according to a synchronization communication hierarchy (e.g., a synchronization signal (SS) hierarchy) that includes multiple synchronization communications (e.g., SS blocks), as described below in conjunction with Figure 3B .

[0048] Figure 3B is a diagram illustrating an example SS hierarchy, which is an example of a synchronization communication hierarchy. As shown in Figure 3B , the SS hierarchy may include an SS burst set, which may include multiple SS bursts (identified as SS burst 0 to SS burst B-1, where B is the maximum number of repetitions of SS bursts that can be transmitted by the base station). As further shown, each SS burst may include one or more SS blocks (identified as SS block 0 to SS block (b max_SS-1), where b max_SS -1 is the maximum number of SS blocks that can be carried by an SS burst). In some aspects, different SS blocks can be beamformed differently. The SS burst set can be transmitted periodically by a wireless node, such as every X milliseconds, as Figure 3B shown. In some aspects, the SS burst set can have a fixed or dynamic length, as shown in Figure 3B as Y milliseconds.

[0049] Figure 3B The SS burst set shown in is an example of a synchronization communication set, and other synchronization communication sets can be used in combination with the techniques described herein. Additionally, Figure 3B the SS block shown in is an example of synchronization communication, and other synchronization communications can be used in combination with the techniques described herein.

[0050] In some aspects, the SS block includes resources carrying PSS, SSS, PBCH, and / or other synchronization signals (e.g., the third synchronization signal (TSS)) and / or synchronization channels. In some aspects, multiple SS blocks are included in an SS burst, and PSS, SSS, and / or PBCH can be the same across each SS block of the SS burst. In some aspects, a single SS block can be included in an SS burst. In some aspects, the SS block can be at least four symbol periods in length, where each symbol carries one or more of PSS (e.g., occupying one symbol), SSS (e.g., occupying one symbol), and / or PBCH (e.g., occupying two symbols).

[0051] In some aspects, the symbols of the SS block are consecutive, as shown in Figure 3B shown. In some aspects, the symbols of the SS block are non-consecutive. Similarly, in some aspects, one or more SS blocks of an SS burst can be transmitted in consecutive radio resources (e.g., consecutive symbol periods) during one or more time slots. Additionally or alternatively, one or more SS blocks of an SS burst can be transmitted in non-consecutive radio resources.

[0052] In some aspects, the SS burst can have a burst period, whereby the SS blocks of the SS burst are transmitted by a base station according to the burst period. In other words, these SS blocks can be repeated during each SS burst. In some aspects, the SS burst set can have a burst set periodicity, whereby the SS bursts of the SS burst set are transmitted by a base station according to a fixed burst set periodicity. In other words, the SS bursts can be repeated during each SS burst set.

[0053] The base station may transmit system information, such as system information blocks (SIBs), on the physical downlink shared channel (PDSCH) in certain time slots. The base station may transmit control information / data on the physical downlink control channel (PDCCH) in C symbol periods of a time slot, where B may be configurable for each time slot. The base station may transmit traffic data and / or other data on the PDSCH in the remaining symbol periods of each time slot.

[0054] As indicated above, Figure 3A and 3B are provided as examples. Other examples may be different from the examples described with respect to Figure 3A and 3B described.

[0055] Figure 4 Fig. shows an example time slot format 410 with a normal cyclic prefix. The available time-frequency resources may be partitioned into resource blocks. Each resource block may cover a set of subcarriers (e.g., 12 subcarriers) in a time slot and may include several resource elements. Each resource element may cover one subcarrier in one symbol period (e.g., in time) and may be used to transmit one modulation symbol that may be a real value or a complex value.

[0056] For FDD in some telecommunication systems (e.g., NR), an interleaving structure may be used for each of the downlink and the uplink. For example, Q strands of interleaving with indices 0 to Q–1 may be defined, where Q may be equal to 4, 6, 8, 10, or some other value. Each strand of interleaving may include time slots spaced Q frames apart. Specifically, interleaving q may include time slots q, q + Q, q + 2Q, etc., where q ∈ {0, …, Q–1}.

[0057] The UE may be within the coverage of multiple BSs. One of these BSs may be selected to serve the UE. The serving BS may be selected at least in part based on various criteria such as received signal strength, received signal quality, path loss, etc. The received signal quality may be quantified by the signal-to-noise interference ratio (SNIR), or the reference signal received quality (RSRQ), or some other metric. The UE may operate in a strong interference scenario, in which the UE may observe high interference from one or more interfering BSs.

[0058] While aspects of the examples described herein may be associated with NR or 5G technology, aspects of the present disclosure may be applicable to other wireless communication systems. New Radio (NR) may refer to a radio configured to operate according to a new air interface (e.g., different from an air interface based on Orthogonal Frequency Division Multiple Access (OFDMA)) or a fixed transport layer (e.g., different from Internet Protocol (IP)). In aspects, NR may utilize OFDM with a cyclic prefix (referred to herein as cyclic prefix OFDM or CP-OFDM) and / or SC-FDM on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using time division duplex (TDD). In aspects, NR may utilize, for example, OFDM with a cyclic prefix (referred to as CP-OFDM herein) and / or Discrete Fourier Transform Spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) on the uplink, may utilize CP-OFDM on the downlink and include support for half-duplex operation using TDD. NR may include enhanced mobile broadband (eMBB) services targeted at wide bandwidths (e.g., 80 megahertz (MHz) and above), millimeter wave (mmW) targeted at high carrier frequencies (e.g., 60 gigahertz (GHz)), massive machine type communication (mMTC) targeted at non-backward compatible MTC technology, and / or mission critical targeted at ultra-reliable low latency communication (URLLC) services.

[0059] In some aspects, a single component carrier bandwidth of 100 MHz may be supported. An NR resource block may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) over a duration of 0.1 millisecond (ms). Each radio frame may include 40 time slots and may have a length of 10 ms. Thus, each time slot may have a length of 0.25 ms. Each time slot may indicate a link direction for data transmission (e.g., DL or UL) and the link direction for each time slot may be switched dynamically. Each time slot may include DL / UL data as well as DL / UL control data.

[0060] Beamforming may be supported and beam directions may be configured dynamically. MIMO transmission with precoding may also be supported. MIMO configurations in the DL may support up to 8 transmit antennas (multi-layer DL transmission with up to 8 streams) and up to 2 streams per UE. Multi-layer transmission with up to 2 streams per UE may be supported. Aggregation of multiple cells may be supported using up to 8 serving cells. Alternatively, NR may support different air interfaces other than the OFDM-based interface. An NR network may include entities such as a central unit or a distributed unit.

[0061] As indicated above, Figure 4 is provided as an example. Other examples may be different from the examples described with respect to Figure 4 above.

[0062] A UE (e.g., UE 120) can use a discontinuous reception (DRX) cycle to save power. One type of DRX cycle is a connected-mode DRX (C-DRX) cycle. During periods of traffic inactivity, the UE can switch to C-DRX operation to save power. The C-DRX cycle can be configured at least in part based on an inactivity timer, a short DRX timer, a short DRX cycle, and a long DRX cycle. The UE can wake up from a sleep state to monitor the PDCCH at least in part based on the short DRX cycle and the long DRX cycle. The period during which the UE wakes up at least in part based on the DRX cycle can be referred to as the on-duration. In addition to the on-duration, the UE can remain asleep, which can be referred to as the off state or the off-duration. During the off-duration, the network (e.g., BS110, network controller 130, etc.) may not expect the UE to transmit or receive signals. If the UE detects a PDCCH during the on-duration, the UE can remain active to transmit or receive data. Otherwise, the UE may go to sleep at the end of the on-duration. Thus, when there is no traffic scheduled for the UE, the UE can remain asleep, thereby saving the power that would otherwise be used to check the PDCCH at each scheduling occasion.

[0063] The UE can further save power by using a wake-up signal (WUS) technique. When using the WUS technique, the UE can wake up within the on-duration only if a WUS is received before the on-duration of the C-DRX cycle. Once the UE receives the WUS, the UE can activate the modem within the next on-duration. Thus, the UE can save power and processor resources. In addition, by skipping the on-duration when the WUS has not been received, the UE saves additional power.

[0064] The WUS can be implemented using various types of signals, sequences, transmissions, etc. For example, the WUS can be reference-signal based (e.g., can be implemented by a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a demodulation reference signal (DMRS), etc.), can be PDCCH-based (e.g., can be implemented by PDCCH communication), can be sequence-based (e.g., can be implemented by Gold sequences, Zadoff-Chu sequences, etc.), and so on. Relative to other types of WUS, the PDCCH WUS may be more robust because the PDCCH WUS may have a built-in coding and cyclic redundancy check (CRC) mechanism.

[0065] To detect PDCCH WUS, a UE may monitor a plurality of PDCCH candidate positions configured for the UE and may perform blind decoding on the PDCCH candidate positions to determine whether the PDCCH WUS is located in any of the PDCCH candidate positions. A base station may configure a plurality of PDCCH candidate positions for a corresponding search space set associated with the UE. The base station may configure a plurality of search space sets for a corresponding control resource set (CORESET) assigned to the UE (e.g., including the periodicity and offset of the search space occasion, the duration of the search space occasion (e.g., the number of time slots), the starting symbol in the time slot of the search space). The base station may configure a plurality of CORESETs for a corresponding bandwidth part (BWP) associated with the UE, and the UE may be assigned a plurality of BWPs by the base station.

[0066] In some aspects, the base station may configure a monitoring window (e.g., a time window) for the UE. The monitoring window configured for the UE may include: one or more PDCCH candidate positions among the PDCCH candidate positions configured for the UE that the UE is to monitor for PDCCH WUS monitoring (e.g., a subset of the PDCCH candidate positions configured for the UE). The monitoring window for the UE may be configured as a time interval, the number of PDCCH candidate positions, the number of time slots, the number of control channel elements, etc. The UE may monitor the search space set in the monitoring window configured for the UE for PDCCH WUS (e.g., only monitor the monitoring occasions falling within the monitoring window for PDCCH WUS). The monitoring window may start at a configured offset (PS_offset) before the start of the DRX on duration. However, in some cases, the UE may not be able to monitor the monitoring window configured for the UE. For example, the end of the monitoring window may be too close to the start of the on duration such that the UE does not have enough time to wake up within the on duration after the monitoring window. In some cases, the monitoring window configured for the UE may be inefficient. For example, the monitoring window may have a duration similar to the duration of the on duration, thereby minimizing the power savings achievable by the WUS technique.

[0067] Some of the techniques and apparatuses described herein provide a monitoring window that does not conflict with the subsequent on duration of the UE and / or provide a monitoring window that is minimized in terms of duration to be efficient. In some aspects, the UE may monitor a portion of the monitoring window configured for the UE according to one or more criteria. In some aspects, the UE may determine the monitoring window in response to one or more parameters (e.g., UE capability parameters, monitoring parameters, etc.). In this way, the UE may use an effective monitoring window that improves the power savings of the UE to monitor for PDCCH WUS.

[0068] Figure 5FIG. 500 is an illustration depicting an example 500 of monitoring a WUS monitoring window in accordance with aspects of the present disclosure. As Figure 5 shown, UE 120 may communicate with BS 110. Specifically, UE 120 may monitor the PDCCH according to a C-DRX procedure using PDCCH WUS techniques.

[0069] As in Figure 5 shown and indicated by reference numeral 505, BS 110 may transmit a configuration, and UE 120 may receive the configuration. For example, BS 110 may transmit the configuration via radio resource control (RRC) signaling. In some aspects, the configuration may indicate a search space set. For example, the configuration may indicate the periodicity and offset of a search space occasion, the duration of a search space occasion (e.g., the number of time slots), the symbols of a time slot of one or more PDCCH candidate positions (i.e., PDCCH monitoring occasions), etc.

[0070] In some aspects, the configuration may indicate a monitoring window for monitoring the search space set, where only the PDCCH candidate positions within the monitoring window will be monitored for PDCCH WUS. In some aspects, the configuration may identify the start of the monitoring window by an offset from the start of an on-duration (e.g., an on-duration configured by C-DRX configuration). In some aspects, the configuration may identify the end of the monitoring window by the duration of the monitoring window (e.g., from the start of the monitoring window). In some aspects, the configuration may identify the end of the monitoring window by the number of search space occasions to be monitored (e.g., from the start of the monitoring window). For example, the number of search space occasions may be one (e.g., only the first search space occasion after the start of the monitoring window is to be monitored), or the number of search space occasions may be all search space occasions between the start of the monitoring window and the start of the on-duration. As described above, in some aspects, the monitoring window configured by the configuration may be ineffective or inefficient.

[0071] As indicated by reference numeral 510, UE 120 may determine a monitoring window for WUS monitoring. In some aspects, the monitoring window may be a part (e.g., a sub-window) of the monitoring window configured by the configuration (e.g., the part of the monitoring window may have a shorter duration than the monitoring window). For example, UE 120 may determine the monitoring window as a part of the configured monitoring window at least in part based on determining that the configured monitoring window does not meet one or more criteria. In some aspects, one or more criteria may be static (e.g., pre-configured for UE 120).

[0072] In some aspects, one or more criteria may indicate a threshold number (e.g., a maximum number) of time slots. Accordingly, a monitoring window (e.g., a portion of a configured monitoring window) may include up to the threshold number of time slots of the configured monitoring window. That is, UE 120 may determine that the monitoring window will include up to the threshold number of time slots of the configured monitoring window (e.g., at least in part based on determining that the configured monitoring window includes more than the threshold number of time slots).

[0073] In some aspects, one or more criteria may indicate a threshold number (e.g., a maximum number) of PDCCH candidate locations for which UE 120 is to attempt decoding. In other words, one or more criteria may indicate the threshold number of PDCCH candidate locations that UE 120 is to monitor. Accordingly, a monitoring window (e.g., a portion of a configured monitoring window) may include up to the threshold number of PDCCH candidate locations of the configured monitoring window. That is, UE 120 may determine that the monitoring window will include up to the threshold number of PDCCH candidate locations of the configured monitoring window (e.g., at least in part based on determining that the configured monitoring window includes more than the threshold number of PDCCH candidate locations).

[0074] In some aspects, one or more criteria may indicate a threshold number (e.g., a maximum number) of control channel elements (CCEs) for which UE 120 is to perform channel estimation. In other words, one or more criteria may indicate the threshold number of CCEs that UE 120 is to monitor. Accordingly, a monitoring window (e.g., a portion of a configured monitoring window) may include up to the threshold number of CCEs of the configured monitoring window. That is, UE 120 may determine that the monitoring window will include up to the threshold number of CCEs of the configured monitoring window (e.g., at least in part based on determining that the configured monitoring window includes more than the threshold number of CCEs).

[0075] In some aspects, one or more criteria may indicate that the last one or more time slots of a configured monitoring window, the last one or more search space occasions, the last one or more PDCCH candidate positions, etc. will not be monitored (e.g., to provide a guard interval between the monitoring window and the on-duration). Accordingly, in some aspects, a monitoring window (e.g., a portion of a configured monitoring window) may include a set of time slots of the configured monitoring window and may not include the last one or more time slots (e.g., time intervals) of the configured monitoring window. That is, the monitoring window may not include one or more search space occasions associated with the last time slot of the configured monitoring window. In some aspects, a monitoring window (e.g., a portion of a configured monitoring window) may include a set of time slots of the search space occasions of the configured monitoring window and may not include the last one or more search space occasions of the configured monitoring window. In some aspects, a monitoring window (e.g., a portion of a configured monitoring window) may include a set of time slots of the PDCCH candidate positions of the configured monitoring window and may not include the last one or more PDCCH candidate positions of the configured monitoring window.

[0076] In some aspects, UE 120 may determine the monitoring window at least in part based on (e.g., contingent on) one or more parameters (such as one or more parameters related to the capabilities of UE 120, one or more parameters configured by BS110, etc.). In some aspects, UE 120 may determine the monitoring window at least in part based on (e.g., contingent on) the power consumption of UE 120. As an example, UE 120 may determine the monitoring window contingent on at least one of the following: the ratio of the power consumption of UE 120 during an inactive period (e.g., off-duration) to the power consumption of UE 120 during an active period (e.g., on-duration), the duration of the active period, the minimum monitoring window duration, the maximum monitoring window duration, and so on.

[0077] For example, UE 120 may determine the monitoring window according to Equation 1:

[0078]

[0079] where T 窗口 is the duration of the monitoring window, T 开启 is the duration of the on-duration, T 最小 is the minimum monitoring window duration, T 最大 is the maximum monitoring window duration, α is the ratio of the power consumption of UE 120 during the inactive period to the power consumption of UE 120 during the active period, and β is a scaling factor.

[0080] In some aspects, BS110 may (e.g., via RRC signaling) transmit and UE 120 may receive an indication of T最小 , T 最大 and / or the configuration of the value of β. In other words, BS110 can determine T 最小 , T 最大 and / or the value of β. In some aspects, the configuration may indicate the value of T 最小 and may not indicate the value of T 最大 . In such a case, T 最大 can be a default value, such as a value corresponding to the offset used to determine the start of the configured monitoring window, as described above. In some aspects, the configuration may indicate the value of T 最大 and may not indicate the value of T 最小 . In such a case, T 最小 can be a default value, such as one (1). In some aspects, T 开启 can be the value indicated by the DRX configuration sent by BS110 and received by UE 120. In some aspects, BS110 can transmit and UE 120 can receive an indication regarding the monitoring window that UE 120 is to determine at least in part based on one or more parameters (e.g., the configuration in combination with T 最小 , T 最大 and / or β, DRX configuration, etc.).

[0081] In some aspects, as shown by reference numeral 515, UE 120 can (e.g., via UE assistance information, uplink control information, media access control (MAC) control element (CE), etc.) transmit an indication of the capabilities of UE 120 to BS 110 so that BS110 can determine the monitoring window that UE 120 is using. For example, the indication may include an α value. In some cases, the α value may change over time (e.g., due to the traffic level of UE 120). Accordingly, UE 120 can dynamically determine the monitoring window (e.g., upon a change in the α value) and can transmit a corresponding indication of the α value to BS 110.

[0082] As indicated by reference numeral 520, UE 120 may monitor the set of search spaces within a monitoring window determined by UE 120. Similarly, as indicated by reference numeral 525, BS 110 may transmit PDCCH WUS in a search space within the monitoring window being used by UE 120. Accordingly, BS 110 may determine the monitoring window being used by UE 120. In some aspects, BS 110 may determine the monitoring window being used by UE 120 based at least in part on one or more criteria used by UE 120 to determine the monitoring window, as described above. In some aspects, BS 110 may determine the monitoring window being used by UE 120 based at least in part on one or more parameters used by UE 120 to determine the monitoring window, as described above. For example, BS 110 may determine the monitoring window based at least in part on an indication of the capabilities of UE 120 (e.g., α) (and Ts, T 开启 , T 最小 , T 最大 and / or β) received from UE 120 to determine the monitoring window.

[0083] In some aspects, UE 120 may detect PDCCH WUS in the set of search spaces based at least in part on monitoring the set of search spaces within the monitoring window. In this way, UE 120 may use the monitoring window that is effective and improves the power savings of UE 120 to monitor for and detect PDCCH WUS.

[0084] As indicated above, Figure 5 is provided as an example. Other examples may be different from the example described with respect to Figure 5 .

[0085] Figure 6 is a diagram illustrating an example process 600, such as may be performed by a UE, in accordance with various aspects of the present disclosure. Example process 600 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with a wake-up signal monitoring window.

[0086] As shown in Figure 6 , in some aspects, process 600 may include determining a monitoring window for monitoring a set of search spaces for PDCCH WUS, where the monitoring window is part of a configured monitoring window for the set of search spaces (block 610). For example, a UE (e.g., using controller / processor 280, etc.) may determine a monitoring window for monitoring a set of search spaces for PDCCH WUS, as described above. In some aspects, the monitoring window is part of a configured monitoring window for the set of search spaces.

[0087] As Figure 6As further shown in, in some aspects, process 600 may include monitoring the set of WUS search spaces within the monitoring window for the PDCCH WUS (block 620). For example, a UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may monitor the set of WUS search spaces within the monitoring window for the PDCCH WUS, as described above.

In a fourth aspect, alone or in combination with one or more of the first through third aspects, the monitoring window includes up to a threshold number of control channel elements of the configured monitoring window.

[0091] In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, the monitoring window does not include the last one or more time slots of the configured monitoring window. In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, the monitoring window does not include the last one or more search space occasions of the configured monitoring window. In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the monitoring window does not include the last one or more PDCCH candidate positions of the configured monitoring window.

[0092] In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, determining the monitoring window includes: determining the monitoring window in response to a parameter of the UE. In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, the parameter is related to the power consumption of the UE. In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, process 600 includes transmitting an indication of the parameter.

[0093] In an eleventh aspect, either alone or in combination with one or more of the first to tenth aspects, determining the monitoring window includes determining the monitoring window in accordance with at least one of the following: a ratio of an energy consumption of the UE during an inactive period to an energy consumption of the UE during an active period, a duration of the active period, a minimum monitoring window duration, or a maximum monitoring window duration.

[0094] In a twelfth aspect, either alone or in combination with one or more of the first to eleventh aspects, the configured monitoring window is a time window configured for the UE, the time window including one or more PDCCH candidate locations for monitoring to search for the PDCCH WUS.

[0095] Although Figure 6 illustrative boxes of process 600 are shown, in some aspects, process 600 may include additional boxes, fewer boxes, different boxes, or boxes arranged differently than those depicted in Figure 6 . Additionally or alternatively, two or more boxes of process 600 may be executed in parallel.

The receiving component 702 may provide the received communication to one or more other components of the device 700. In some aspects, the receiving component 702 may perform signal processing on the received communication (such as filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding, and other examples), and may provide the processed signal to one or more other components of the device 706.
