[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. Provisional Patent Application No. 62 / 937,688, entitled “WAKEUP SIGNAL MONITORING WINDOW,” filed on November 19, 2019, and U.S. Non-Provisional Patent Application No. 16 / 949,326, entitled “WAKEUP SIGNAL MONITORING WINDOW,” filed on October 26, 2020, which are hereby expressly incorporated herein by reference.

[0003] Public domain

[0004] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for wake-up signal monitoring windows.

[0005] background

[0006] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support 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 / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0007] A wireless communication network may include several base stations (BS) that can support communication of several user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. Downlinks (or forward links) refer to the communication link from a BS to a UE, while uplinks (or reverse links) refer to the communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an Access Point (AP), a Radio Head, a Transmit Receive Point (TRP), a New Radio (NR) BS, a 5G Node B, and the like.

[0008] The above multiple access technologies have been adopted in various telecommunication standards to provide common protocols that enable different user equipment to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP). NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using 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 in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies.

[0025] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be implemented in many different forms and should not be interpreted as being limited to any specific structure or function given throughout the present disclosure. On the contrary, these aspects are provided to make the present disclosure thorough and complete, and it 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 will appreciate that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein can be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods practiced using supplements or other other structures, functionality, or structures and functionality as the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be implemented by one or more elements of the claims.

[0026] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0027] It should be noted that although various aspects may be described herein using terminology typically associated with 3G and / or 4G wireless technologies, various aspects of the present disclosure may be applied in communication systems based on other generations, such as 5G and later generations, including NR technologies.

[0028] Figure 11 is a diagram illustrating a wireless network 100 in which various 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 BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, B node, gNB, 5G B node (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0029] 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., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscriptions. 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 Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. The 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.

[0030] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected to each other and / or to 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 the like using any suitable transport network.

[0031] 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.

[0032] 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).

[0033] 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.

[0034] 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.

[0035] Some UEs may be considered as 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 or to a network (e.g., a wide area network (such as the Internet) or a cellular network), for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as client equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, and the like.

[0036] In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a specific radio access technology (RAT) and may operate on one or more frequencies. RAT may also be referred to as radio technology, air interface, etc. Frequency may also be referred to as carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0037] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. 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.), mesh networks, 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.

[0038] As indicated above, Figure 1 are provided as examples. Other examples may differ from those described in Figure 1 Examples described.

[0039] Figure 2 A diagram showing a design 200 of a base station 110 and a UE 120 is shown, which may be Figure 1One for each base station and one for each UE in the base station 110. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T≧1 and R≧1.

[0040] 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 (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS selected for the 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 (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a 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 modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, position coding may be used to generate synchronization signals to convey additional information.

[0041] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, 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. A MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols where applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller / processor 280. The channel processor may determine 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 UE 120 may be included in a housing.

[0042] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a 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 a TX MIMO processor 266, if 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, uplink signals from the UE 120 as well as other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236, if applicable, and further processed by the receive processor 238 to obtain decoded data and control information sent by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and provide decoded control information to a 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.

[0043] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any other component of the base station 110 may perform one or more techniques associated with the 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 of the Figure 6 The operations of process 600 and / or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 may include: a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and / or UE 120, may perform or direct, for example Figure 6 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0044] In some aspects, UE 120 may include: means for determining a monitoring window for monitoring a search space set for a physical downlink control channel (PDCCH) WUS, wherein the monitoring window is a portion of a configured monitoring window for the search space set; and means for monitoring the search space set within the monitoring window for the PDCCH WUS; etc. In some aspects, such means may include in conjunction with Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and the like.

[0045] As indicated above, Figure 2 are provided as examples. Other examples may differ from those described in Figure 2 Examples described.

[0046] Figure 3A An example frame structure 300 for frequency division duplex (FDD) in a telecommunication system (e.g., NR) is shown. The transmission timeline for each of the downlink and uplink may be divided into units of 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., with 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 3A Each subframe 2 is shown mtime slots, where m is a parameter design for transmission, such as 0, 1, 2, 3, 4, etc.). Each time slot may include a set of L symbol periods. For example, each time slot may include fourteen symbol periods (e.g., Figure 3A ), seven symbol periods, or another number of symbol periods. In the case where a subframe includes two 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, slot-based, symbol-based, etc.

[0047] Although some techniques are described herein in conjunction with frames, subframes, time slots, etc., these techniques may be equally applicable to other types of wireless communication structures, which may be referred to in 5G NR using terms other than "frames," "subframes," "time slots," etc. In some aspects, a "wireless communication structure" may refer to a periodic, time-bounded communication unit defined by a wireless communication standard and / or protocol. Additionally or alternatively, a wireless communication structure may be used in conjunction with a wireless communication standard and / or protocol. Figure 3A The wireless communication structure configurations are different from those shown in FIG.

[0048] In some telecommunications (e.g., NR), a base station may transmit a synchronization (SYNC) signal. For example, a base station may transmit a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and the like on the downlink for each cell supported by the base station. The PSS and SSS may be used by the UE for cell search and acquisition. For example, the PSS may be used by the UE to determine symbol timing, and the SSS may be used by the UE to determine a 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 system information that supports initial access of the UE.

[0049] In some aspects, a base station may transmit a PSS, SSS, and / or PBCH according to a synchronization communication level (e.g., a synchronization signal (SS) level) including multiple synchronization communications (e.g., SS blocks), as described below in conjunction with Figure 3B as described.

[0050] Figure 3B is a diagram illustrating an example SS hierarchy, which is an example of a synchronous communication hierarchy. Figure 3B As shown in FIG. 1 , the SS hierarchy may include an SS burst set, which may include a plurality of SS bursts (identified as SS burst 0 to SS burst B-1, where B is the maximum number of repetitions of the SS burst that may 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 bmax_SS -1 is the maximum number of SS blocks that can be carried by an SS burst). In some aspects, different SS blocks may be beamformed differently. SS burst sets may be transmitted by a wireless node periodically, such as every X milliseconds, e.g. Figure 3B In some aspects, SS burst sets may have fixed or dynamic lengths, such as in Figure 3B is shown as Y milliseconds.

[0051] Figure 3B The SS burst set shown in is an example of a synchronous communication set, and other synchronous communication sets may be used in conjunction with the techniques described herein. Figure 3B The SS blocks shown in are examples of synchronous communications, and other synchronous communications may be used in conjunction with the techniques described herein.

[0052] In some aspects, an SS block includes resources that carry PSS, SSS, PBCH, and / or other synchronization signals (e.g., a third synchronization signal (TSS)) and / or synchronization channels. In some aspects, multiple SS blocks are included in an SS burst, and the PSS, SSS, and / or PBCH may be identical for each SS block across an SS burst. In some aspects, a single SS block may be included in an SS burst. In some aspects, an SS block may be at least four symbol periods in length, with each symbol carrying one or more of a PSS (e.g., occupying one symbol), an SSS (e.g., occupying one symbol), and / or a PBCH (e.g., occupying two symbols).

[0053] In some aspects, the symbols of the SS block are consecutive, such as Figure 3B In some aspects, the symbols of the SS block are non-contiguous. Similarly, in some aspects, one or more SS blocks of an SS burst may be transmitted in contiguous radio resources (e.g., contiguous symbol periods) during one or more time slots. Additionally or alternatively, one or more SS blocks of an SS burst may be transmitted in non-contiguous radio resources.

[0054] In some aspects, an SS burst may have a burst periodicity, whereby each SS block of the SS burst is transmitted by the base station according to the burst periodicity. In other words, the SS blocks may be repeated during each SS burst. In some aspects, an SS burst set may have a burst set periodicity, whereby each SS burst of the SS burst set is transmitted by the base station according to a fixed burst set periodicity. In other words, the SS burst may be repeated during each SS burst set.

[0055] The base station may transmit system information, such as system information blocks (SIBs), on a physical downlink shared channel (PDSCH) in certain time slots. The base station may transmit control information / data on a 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.

[0056] As indicated above, Figure 3A and 3B are provided as examples. Other examples may differ from those described in Figure 3A and 3B Examples described.

[0057] Figure 4 An example slot format 410 with a normal cyclic prefix is ​​shown. Available time-frequency resources may be divided into resource blocks. Each resource block may cover a set of subcarriers (e.g., 12 subcarriers) in one 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 send one modulation symbol, which may be a real value or a complex value.

[0058] For FDD in certain telecommunication systems (e.g., NR), an interleaving structure may be used for each of the downlink and uplink. For example, Q interleavings with indices 0 to Q–1 may be defined, where Q may be equal to 4, 6, 8, 10, or some other value. Each interleaving may include time slots spaced apart by Q frames. Specifically, interleaving q may include time slots q, q+Q, q+2Q, etc., where q∈{0,…,Q–1}.

[0059] The UE may be located within the coverage of multiple BSs. One of these BSs may be selected to serve the UE. The serving BS may be selected based at least in part on various criteria such as received signal strength, received signal quality, path loss, etc. The received signal quality may be quantified by a signal-to-noise-and-interference ratio (SNIR), or a 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.

[0060] Although 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. A new radio (NR) may refer to a radio configured to operate according to a new air interface (e.g., an air interface different from an orthogonal frequency division multiple access (OFDMA)-based air interface) or a fixed transport layer (e.g., different from an Internet Protocol (IP)). In various aspects, NR may utilize OFDM with CP (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 various aspects, NR may, for example, utilize OFDM with CP (referred to herein as CP-OFDM) 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 targeting wide bandwidth (e.g., 80 megahertz (MHz) and above), millimeter wave (mmW) targeting high carrier frequencies (e.g., 60 gigahertz (GHz)), massive MTC (mMTC) targeting non-backward compatible MTC technologies, and / or mission critical services targeting ultra-reliable low latency communications (URLLC) services.

[0061] In some aspects, a single component carrier bandwidth of 100 MHz may be supported. NR resource blocks may span 12 subcarriers with a subcarrier bandwidth of 60 or 120 kilohertz (kHz) over a duration of 0.1 milliseconds (ms). Each radio frame may include 40 slots and may have a length of 10 ms. Thus, each slot may have a length of 0.25 ms. Each slot may indicate a link direction (e.g., DL or UL) for data transmission and the link direction for each slot may be switched dynamically. Each slot may include DL / UL data and DL / UL control data.

[0062] Beamforming may be supported and the beam direction may be dynamically configured. MIMO transmission with precoding may also be supported. MIMO configuration in 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 OFDM-based interfaces. NR networks may include entities such as central units or distributed units.

[0063] As indicated above, Figure 4 are provided as examples. Other examples may differ from those described in Figure 4 Examples described.

[0064] A UE (e.g., UE 120) may use a discontinuous reception (DRX) cycle to save power. One type of DRX cycle is a connected mode DRX (C-DRX) cycle. During a period of inactive traffic, the UE may switch to C-DRX operation to save power. The C-DRX cycle may be configured at least in part based on an inactive timer, a short DRX timer, a short DRX cycle, and a long DRX cycle. The UE may wake up from a sleep state to monitor the PDCCH based at least in part on a short DRX cycle and a long DRX cycle. The period during which the UE wakes up based at least in part on the DRX cycle may be referred to as an on duration. In addition to the on duration, the UE may remain asleep, which may be referred to as an off state or off duration. During the off duration, the network (e.g., BS 110, network controller 130, etc.) may not expect the UE to transmit or receive a signal. If the UE detects a PDCCH during the on duration, the UE may remain active to transmit or receive data. Otherwise, the UE may go to sleep at the end of the on duration. Therefore, when no traffic is scheduled for a UE, the UE can remain asleep, thereby saving power that would otherwise be used to check the PDCCH at every scheduling opportunity.

[0065] 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 the 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. Therefore, 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.

[0066] WUS may be implemented using various types of signals, sequences, transmissions, etc. For example, WUS may be reference signal-based (e.g., may be implemented by a channel state information reference signal (CSI-RS), a tracking reference signal (TRS), a demodulation reference signal (DMRS), etc.), may be PDCCH-based (e.g., may be implemented by PDCCH communication), may be sequence-based (e.g., may be implemented by a Gold sequence, a Zadoff Chu sequence, etc.), etc. PDCCH WUS may be more robust relative to other types of WUS because PDCCH WUS may have built-in coding and cyclic redundancy check (CRC) mechanisms.

[0067] In order to detect PDCCH WUS, the UE may monitor a number 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. The base station may configure multiple PDCCH candidate positions for a corresponding search space set associated with the UE. The base station may configure multiple search space sets (e.g., including the periodicity and offset of the search space opportunity, the duration of the search space opportunity (e.g., the number of time slots), and the starting codeword in the time slot of the search space) for a corresponding control resource set (CORESET) assigned to the UE. The base station may configure multiple CORESETs for a corresponding bandwidth part (BWP) associated with the UE, and the UE may be assigned multiple BWPs by the base station.

[0068] In some aspects, a base station may configure a monitoring window (e.g., a time window) for a UE. The monitoring window configured for a UE may include: one or more PDCCH candidate positions (e.g., a subset of PDCCH candidate positions configured for the UE) that the UE is to monitor in order to find PDCCH WUS monitoring. 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, and the like. The UE may monitor a search space set in a monitoring window configured for the UE to find PDCCH WUS (e.g., only monitoring the monitoring opportunities that fall within the monitoring window to find 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 so 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 that of the turn-on duration, thereby minimizing the power savings that may be achieved through the WUS technique.

[0069] Some techniques and devices described herein provide a monitoring window that does not conflict with the subsequent opening duration of the UE and / or provide a monitoring window that is minimized in duration to obtain high efficiency. In some aspects, the UE can monitor a portion of the monitoring window configured for the UE according to one or more criteria. In some aspects, the UE can determine the monitoring window depending on one or more parameters (e.g., UE capability parameters, monitoring parameters, etc.). In this way, the UE can use an effective and improved monitoring window for the power saving of the UE to monitor to find the PDCCH WUS.

[0070] Figure 5is a diagram illustrating an example 500 of monitoring a WUS monitoring window according to aspects of the present disclosure. Figure 5 As shown in FIG, UE 120 may communicate with BS 110. Specifically, UE 120 may monitor the PDCCH according to a C-DRX procedure using a PDCCH WUS technique.

[0071] As in Figure 5 1 and as 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 a periodicity and offset of search space opportunities, a duration of search space opportunities (e.g., a number of time slots), a symbol of a time slot of one or more PDCCH candidate locations (i.e., a PDCCH monitoring opportunity), and the like.

[0072] In some aspects, the configuration may indicate a monitoring window for monitoring a search space set, wherein only PDCCH candidate positions in the monitoring window will be monitored to find a PDCCH WUS. In some aspects, the configuration may identify the start of the monitoring window by an offset from the start of the on duration (e.g., the on duration configured by the 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 opportunities to be monitored (e.g., from the start of the monitoring window). For example, the number of search space opportunities may be one (e.g., only the first search space opportunity after the start of the monitoring window is to be monitored), or the number of search space opportunities may be all search space opportunities 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 invalid or inefficient.

[0073] 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 portion (e.g., a sub-window) of the monitoring window configured by the configuration (e.g., the portion of the monitoring window may have a shorter duration than the monitoring window). For example, UE 120 may determine the monitoring window to be a portion of the configured monitoring window based at least in part on determining that the configured monitoring window does not satisfy one or more criteria. In some aspects, the one or more criteria may be static (e.g., pre-configured for UE 120).

[0074] In some aspects, one or more criteria may indicate a threshold number of time slots (e.g., a maximum number). Accordingly, the monitoring window (e.g., a portion of a configured monitoring window) may include up to a threshold number of time slots of the configured monitoring window. That is, UE 120 may determine that the monitoring window will include up to a threshold number of time slots of the configured monitoring window (e.g., based at least in part on determining that the configured monitoring window includes more than the threshold number of time slots).

[0075] In some aspects, one or more criteria may indicate a threshold number (e.g., a maximum number) of PDCCH candidate positions that the UE 120 is to attempt to decode. In other words, the one or more criteria may indicate a threshold number of PDCCH candidate positions that the UE 120 is to monitor. Accordingly, the monitoring window (e.g., a portion of a configured monitoring window) may include up to a threshold number of PDCCH candidate positions of the configured monitoring window. That is, the UE 120 may determine that the monitoring window will include up to a threshold number of PDCCH candidate positions of the configured monitoring window (e.g., based at least in part on determining that the configured monitoring window includes more than a threshold number of PDCCH candidate positions).

[0076] 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 a threshold number of CCEs to be monitored by UE 120. Accordingly, a monitoring window (e.g., a portion of a configured monitoring window) may include up to a threshold number of CCEs of the configured monitoring window. That is, UE 120 may determine that the monitoring window will include up to a threshold number of CCEs of the configured monitoring window (e.g., based at least in part on determining that the configured monitoring window includes more than the threshold number of CCEs).

[0077] In some aspects, one or more criteria may indicate that the last one or more time slots, the last one or more search space opportunities, the last one or more PDCCH candidate positions, etc. of the configured monitoring window will not be monitored (e.g., providing a guard interval between the monitoring window and the opening duration). Accordingly, in some aspects, the monitoring window (e.g., a portion of the 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 interval) of the configured monitoring window. That is, the monitoring window may not include one or more search space opportunities associated with the last time slot of the configured monitoring window. In some aspects, the monitoring window (e.g., a portion of the configured monitoring window) may include a set of time slots of the search space opportunities of the configured monitoring window, and may not include the last one or more search space opportunities of the configured monitoring window. In some aspects, the monitoring window (e.g., a portion of the 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.

[0078] In some aspects, UE 120 may determine the monitoring window based at least in part on (e.g., as a function of) one or more parameters, such as one or more parameters related to capabilities of UE 120, one or more parameters configured by BS 110, etc. In some aspects, UE 120 may determine the monitoring window based at least in part on (e.g., as a function of) energy consumption of UE 120. As an example, UE 120 may determine the monitoring window as a function of at least one of: a ratio of energy consumption of UE 120 during an inactive time period (e.g., an off duration) to energy consumption of UE 120 during an active time period (e.g., an on duration), a duration of the active time period, a minimum monitoring window duration, a maximum monitoring window duration, etc.

[0079] For example, UE 120 may determine the monitoring window according to Formula 1:

[0080]

[0081] Formula 1

[0082] Where T 窗口 is the duration of the monitoring window, T 开启 is the duration of the opening 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 energy consumption of UE 120 during the inactive time period to the energy consumption of UE 120 during the active time period, and β is a scaling factor.

[0083] In some aspects, BS 110 may transmit (eg, via RRC signaling) and UE 120 may receive an indication T 最小 , T 最大 In other words, BS 110 may determine T 最小 , T 最大 and / or the value of β. In some aspects, the configuration may indicate T 最小 value and may not indicate T 最大 In this case, T 最大 may be a default value, such as a value corresponding to an offset for determining the start of a configured monitoring window, as described above. In some aspects, the configuration may indicate that T 最大 value and may not indicate T 最小 In this case, T 最小 can be a default value, such as one (1). In some aspects, T 开启 may be a value indicated by a DRX configuration sent by BS 110 and received by UE 120. In some aspects, BS 110 may transmit and UE 120 may receive information regarding a DRX configuration that UE 120 is to perform based at least in part on one or more parameters (e.g., in combination with T 最小 , T 最大 and / or β configuration, DRX configuration, etc.) to determine the indication of the monitoring window.

[0084] In some aspects, as shown by reference numeral 515, UE 120 may transmit an indication of the capabilities of UE 120 to BS 110 (e.g., via UE assistance information, uplink control information, medium access control (MAC) control element (CE), etc.) to enable BS 110 to determine the monitoring window being used by UE 120. For example, the indication may include an α value. In some cases, the α value may change over time (e.g., due to traffic levels of UE 120). Accordingly, UE 120 may dynamically determine the monitoring window (e.g., upon changes to the α value) and may transmit a corresponding indication of the α value to BS 110.

[0085] As indicated by reference numeral 520, UE 120 may monitor the search space set within a monitoring window determined by UE 120. Similarly, as indicated by reference numeral 525, BS 110 may transmit a PDCCH WUS in a search space set 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 being 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 being used by UE 120 to determine the monitoring window, as described above. For example, BS 110 may determine the monitoring window being used by UE 120 based at least in part on capabilities (e.g., α) of UE 120 received from UE 120 (and T determined by BS 110). 开启 , T 最小 , T 最大 and / or β) to determine the monitoring window.

[0086] In some aspects, UE 120 can detect PDCCH WUS in a search space set based at least in part on monitoring the search space set within a monitoring window. In this way, UE 120 can monitor for and detect PDCCH WUS using a monitoring window that is efficient and improves power conservation for UE 120.

[0090] like Figure 6As further shown in FIG. 6 , in some aspects, process 600 may include monitoring the WUS search space set within the monitoring window to find the PDCCH WUS (block 620). For example, the UE (e.g., using antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, etc.) may monitor the WUS search space set within the monitoring window to find the PDCCH WUS, as described above.

[0094] In a fifth aspect, either alone or in combination with one or more of the first to fourth aspects, the monitoring window does not include the last one or more time slots of the configured monitoring window. In a sixth aspect, either alone or in combination with one or more of the first to fifth aspects, the monitoring window does not include the last one or more search space opportunities of the configured monitoring window. In a seventh aspect, either alone or in combination with one or more of the first to sixth aspects, the monitoring window does not include the last one or more PDCCH candidate positions of the configured monitoring window.

In a ninth aspect, either alone or in combination with one or more of the first to eighth aspects, the parameter is related to energy consumption of the UE. In a tenth aspect, either alone or in combination with one or more of the first to ninth aspects, process 600 comprises transmitting an indication of a parameter.

[0096] In the eleventh aspect, alone or in combination with one or more of the first to tenth aspects, determining the monitoring window includes determining the monitoring window as a function of at least one of: the ratio of the energy consumption of the UE during the inactive time period to the energy consumption of the UE during the active time period, the duration of the active time period, the minimum monitoring window duration, or the maximum monitoring window duration.
