Description

Technical Field

[0001] The present invention relates to wireless communications, and more particularly to apparatus, systems and methods for medium access control (MAC) behavior and radio resource control (RRC) configuration for uplink (UL) wake-up signals (WUS) of connected user equipment devices (UEs), for example in cellular systems such as LTE systems, 5GNR systems and beyond.

[0002] Related technical description

[0003] The use of wireless communication systems is growing rapidly. In recent years, wireless devices such as smart phones, wearable devices or accessory devices, and tablet computers have become increasingly sophisticated. In addition to supporting phone calls, many mobile devices now also provide access to the Internet, email, text messaging, and navigation using the Global Positioning System (GPS), and are capable of operating sophisticated applications that utilize these functions.

[0004] Long Term Evolution (LTE) is currently the technology of choice for most wireless network operators around the world, providing mobile broadband data and high-speed Internet access to their subscriber base. LTE was first proposed in 2004 and first standardized in 2008. Since then, as the use of wireless communication systems has grown exponentially, the need for wireless network operators to support higher capacity for a higher density of mobile broadband users has also risen. As a result, research into new radio access technologies began in 2015, and in 2017, the first version of Fifth Generation New Radio (5G NR) was standardized.

[0005] 5G-NR (also referred to as NR) provides higher capacity for a higher density of mobile broadband users compared to LTE, while also supporting ultra-reliable and massive machine-type communications from device to device, as well as lower latency and / or lower battery consumption. In addition, NR may allow for more flexible UE scheduling compared to current LTE. Therefore, efforts are being made to continue the development of 5G-NR to take advantage of the higher throughput possible at higher frequencies. Summary of the invention

[0006] Embodiments relate to wireless communications, and more particularly to apparatus, systems, and methods for MAC behavior and RRC configuration for UL WUS of connected UEs, such as in 5G NR systems and above.

[0007] For example, in some embodiments, the UE may be configured to receive an indication of resources for the UL WUS from a base station. In addition, the UE may be configured to receive one or more trigger conditions for the transmission of the UL WUS from the base station. The indication may include a prohibition timer and a maximum number of transmissions per UL WUS resource. The resource for the UL WUS may be a periodic or aperiodic UL resource. The one or more trigger conditions for the transmission of the UL WUS may be received via a system information block or via radio resource control signaling. The UE may be configured to configure the UL WUS based at least in part on the indication of resources for the UL WUS and the one or more trigger conditions for the transmission of the UL WUS.

[0008] As another example, in some embodiments, the UE may be configured to detect a trigger condition for transmission of a UL WUS and determine whether the conditions for transmitting the UL WUS are met, including determining that at a time of an upcoming UL WUS transmission opportunity, a prohibit timer is not running, and determining that the UL WUS transmission opportunity does not overlap with a measurement gap. The trigger condition may be detected at a medium access control (MAC) layer of the UE.

[0009] As a further example, in some embodiments, the UE may be configured to receive a plurality of UL WUS configurations from a base station and select a UL WUS resource to indicate a type of transmission and / or a UL resource that the UE intends to use for an upcoming transmission, wherein each UL WUS configuration in the plurality of UL WUS configurations is associated with a respective UL WUS resource. The selection of the UL WUS resource may indicate that the UE intends to transmit a RACH transmission in an upcoming UL resource, that the UE intends to transmit a configuration grant physical uplink shared channel (CG-PUSCH) transmission in an upcoming UL resource, which upcoming CG-PUSCH resource the UE intends to use, which upcoming RACH resource the UE intends to use, and / or that the UE intends to transmit in an upcoming cell DRX / DTX off duration.

[0010] As yet another example, in some embodiments, the UE may be configured to receive an indication from a base station that the base station will wake up in one or more upcoming UL resources in response to sending the UL WUS, and to send pending RACH or PUSCH data to the base station in at least a portion of the one or more upcoming UL resources.

[0011] As yet another example, in some embodiments, the UE may be configured to receive an indication from the base station that the base station will not wake up in one or more upcoming UL resources in response to sending the UL WUS, and to suspend pending RACH or PUSCH data in the one or more upcoming UL resources.

[0012] As an additional example, in some embodiments, the UE may be configured to determine that upcoming UL resources occur in a turn-on duration or upcoming cell DRX / DTX in response to not receiving a response to a UL WUS sent to the base station, and to send pending RACH or PUSCH data to the base station in at least a portion of the upcoming UL resources.

[0013] As another additional example, in some embodiments, the UE may be configured to determine that an upcoming UL resource occurs in an on-time or an upcoming cell DRX / DTX in response to not receiving a response to a UL WUS sent to the base station, and to suspend pending RACH or PUSCH data in the upcoming UL resource.

[0014] The techniques described herein may be implemented in and / or used with a variety of different types of devices, including, but not limited to, unmanned aerial vehicles (UAVs), unmanned aerial vehicle controllers (UACs), UTM servers, base stations, access points, cellular telephones, tablet computers, wearable computing devices, portable media players, and any of a variety of other computing devices.

[0069] the term

[0070] The following is a glossary of terms used in this disclosure:

[0071] Memory medium—any of various types of non-transitory memory devices or storage devices. The term "memory medium" is intended to include installation media, such as CD-ROM, floppy disk, or tape devices; computer system memory or random access memory, such as DRAM, DDR RAM, SRAM, EDO RAM, Rambus RAM, etc.; non-volatile memory, such as flash memory, magnetic media, such as hard disk drives or optical storage devices; registers or other similar types of memory elements, etc. The memory medium may also include other types of non-transitory memory or combinations thereof. In addition, the memory medium may be located in a first computer system executing a program, or may be located in a different second computer system connected to the first computer system via a network such as the Internet. In the latter example, the second computer system may provide program instructions to the first computer for execution. The term "memory medium" may include two or more memory media, which may reside in different locations in different computer systems connected, for example, via a network. The memory medium may store program instructions (e.g., embodied as a computer program) that may be executed by one or more processors.

[0072] Carrier medium—storage media as described above, as well as physical transmission media such as a bus, network, and / or other physical transmission media that convey signals such as electrical, electromagnetic, or digital signals.

[0073] Programmable hardware element - includes various hardware devices that include multiple programmable function blocks connected via programmable interconnects. Examples include FPGAs (field programmable gate arrays), PLDs (programmable logic devices), FPOAs (field programmable object arrays), and CPLDs (complex PLDs). Programmable function blocks can range from fine-grained (combinatorial logic or lookup tables) to coarse-grained (arithmetic logic units or processor cores). Programmable hardware elements may also be referred to as "configurable logic units."

[0074] Computer system (or computer) - any of various types of computing or processing systems, including a personal computer system (PC), a mainframe computer system, a workstation, a network appliance, an Internet appliance, a personal digital assistant (PDA), a television system, a grid computing system, or other devices or combinations of devices. In general, the term "computer system" can be broadly defined to encompass any device (or combination of devices) having at least one processor that executes instructions from a memory medium.

[0075] User Equipment (UE) (or "UE device") - any of various types of computer system devices that are mobile or portable and perform wireless communications. Examples of UE devices include mobile phones or smart phones (e.g., iPhone TM, based on Android TM phones), portable gaming devices (e.g., Nintendo DS TM , PlayStation Portable TM 、Gameboy Advance TM , iPhone TM ), laptops, wearable devices (e.g., smart watches, smart glasses), PDAs, portable Internet devices, music players, data storage devices, other handheld devices, unmanned aerial vehicles (UAVs) (e.g., drones), UAV controllers (UACs), etc. In general, the term "UE" or "UE device" can be broadly defined to cover any electronic device, computing device, and / or telecommunication device (or combination of devices) that is easily transportable by a user and capable of wireless communication.

[0076] Base Station—The term “base station” has the full breadth of its ordinary meaning and includes at least a wireless communication station that is installed at a fixed location and used to communicate as part of a wireless telephone system or radio system.

[0077] Processing element (or processor) - refers to various elements or combinations of elements that are capable of performing functions in a device, such as user equipment or a cellular network device. Processing elements may include, for example, processors and associated memory, portions or circuits of individual processor cores, entire processor cores, processor arrays, circuits such as ASICs (application specific integrated circuits), programmable hardware elements such as field programmable gate arrays (FPGAs), and any of the above combinations.

[0078] Channel - a medium used to convey information from a sender (transmitter) to a receiver. It should be noted that since the characteristics of the term "channel" may vary according to different wireless protocols, the term "channel" as used herein may be considered to be used in a manner that conforms to the standards of the type of device to which the term is used. In some standards, the channel width may be variable (e.g., depending on device capabilities, frequency band conditions, etc.). For example, LTE may support scalable channel bandwidths of 1.4 MHz to 20 MHz. In contrast, a WLAN channel may be 22 MHz wide, while a Bluetooth channel may be 1 MHz wide. Other protocols and standards may include different definitions of channels. In addition, some standards may define and use multiple types of channels, for example, different channels for uplink or downlink and / or different channels for different purposes such as data, control information, etc.

[0079] Frequency band—The term “frequency band” has the full breadth of its ordinary meaning and includes at least a segment of the spectrum (eg, radio frequency spectrum) in which channels are used or set aside for the same purpose.

[0080] Wi-Fi—The term "Wi-Fi" (or WiFi) has the full scope of its usual meaning and includes at least wireless communication networks or RATs that are served by wireless LAN (WLAN) access points and provide connectivity to the Internet through these access points. Most modern Wi-Fi networks (or WLAN networks) are based on the IEEE 802.11 standard and are marketed under the name "Wi-Fi". Wi-Fi (WLAN) networks are distinct from cellular networks.

[0081] 3GPP access—refers to access (e.g., radio access technology) specified by the 3GPP standards. These accesses include, but are not limited to, GSM / GPRS, LTE, LTE-A, and / or 5G NR. In general, 3GPP access refers to various types of cellular access technologies.

[0082] Non-3GPP access - refers to any access (e.g., radio access technology) not specified by the 3GPP standards. These accesses include, but are not limited to, WiMAX, CDMA2000, Wi-Fi, WLAN, and / or fixed networks. Non-3GPP accesses can be divided into two categories, "trusted" and "untrusted": trusted non-3GPP accesses can interact directly with the Evolved Packet Core (EPC) and / or 5G Core (5GC), while untrusted non-3GPP interoperates with the EPC / 5GC via network entities (such as Evolved Packet Data Gateways and / or 5GNR Gateways). In general, non-3GPP access refers to various types of non-cellular access technologies.

[0083] Automatic—refers to an action or operation being performed by a computer system (e.g., software executed by a computer system) or a device (e.g., a circuit, a programmable hardware element, an ASIC, etc.) without the action or operation being directly specified or performed by a user input. Thus, the term "automatic" is in contrast to a user manually performing or specifying an action (where the user provides input to directly perform the action). An automatic process may be initiated by input provided by a user, but subsequent actions performed "automatically" are not specified by the user, i.e., are not performed "manually," where the user specifies each action to be performed. For example, a user filling out an electronic form by selecting each field and providing input specifying information (e.g., by typing in information, selecting checkboxes, radio selections, etc.) is manually filling out the form, even though the computer system must update the form in response to the user action. The form may be automatically filled out by a computer system, where the computer system (e.g., software executed on the computer system) analyzes the fields of the form and fills out the form without any user input specifying the answers to the fields. As indicated above, a user may invoke automatic filling out of a form, but not participate in the actual filling out of the form (e.g., the user does not manually specify the answers to the fields but rather they are automatically completed). This specification provides various examples of operations that are automatically performed in response to actions that a user has taken.

[0084] Approximately - refers to a value that is almost correct or exact. For example, approximately can refer to a value that is within 1% to 10% of an exact (or expected) value. However, it should be noted that the actual threshold value (or tolerance) may be application dependent. For example, in some embodiments, "approximately" may mean within 0.1% of some specified or expected value, while in various other embodiments, the threshold value may be, for example, 2%, 3%, 5%, etc., depending on the expectations or requirements of a particular application.

[0085] Concurrency - refers to parallel execution or implementation, where tasks, processes, or programs are executed in an at least partially overlapping manner. For example, concurrency can be achieved using "strong" or strict parallelism, where tasks are executed (at least partially) in parallel on respective computing elements, or using "weak parallelism", where tasks are executed in an interleaved manner (e.g., by time multiplexing of execution threads).

[0086] Various components may be described as being "configured to" perform one or more tasks. In such contexts, "configured to" is a broad statement that generally means "having a structure" that performs one or more tasks during operation. Thus, even when the component is not currently performing a task, the component may be configured to perform the task (e.g., a collection of electrical conductors may be configured to electrically connect a module to another module even when the two modules are not connected). In some contexts, "configured to" may be a broad statement that generally means "having a structure" that performs one or more tasks during operation. Thus, even when the component is not currently turned on, the component may be configured to perform a task. Typically, the circuitry that forms the structure corresponding to "configured to" may include hardware circuits.

[0087] For ease of description, various components may be described as performing one or more tasks. Such descriptions should be interpreted as including the phrase "configured to". Representing a component configured to perform one or more tasks expressly intends that the component does not invoke the interpretation of 35 U.S.C. §112(f).

[0088] Figure 1A and Figure 1B :Communication System

[0089] Figure 1A A simplified example wireless communication system according to some embodiments is illustrated. Note that Figure 1A The system is merely one example of a possible system, and features of the present disclosure may be implemented in any of a variety of systems, as desired.

[0090] As shown, the exemplary wireless communication system includes a base station 102A, which communicates with one or more wireless devices (such as user equipment 106A, 106B, etc. to 106N) and accessory devices (such as user equipment 107A, 107B) via a transmission medium. Each user equipment in the user equipment may be referred to as a "user equipment" (UE) in this article. Therefore, user equipment 106 and 107 are referred to as UE or UE devices.

[0091] Base station (BS) 102A may be a base transceiver station (BTS) or a cell site ("cellular base station"), and may include hardware that enables wireless communications with UEs 106A-106N and UEs 107A and 107B.

[0092] The communication area (or coverage area) of a base station may be referred to as a "cell". The base station 102A and the UE 106 / 107 may be configured to communicate over a transmission medium using any of a variety of radio access technologies (RATs), which are also referred to as wireless communication technologies or telecommunication standards, such as GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces), LTE, Advanced LTE (LTE-A), 5G New Radio (5G NR), HSPA, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc. It should be noted that if the base station 102A is implemented in the context of LTE, it may alternatively be referred to as an "eNodeB" or "eNB". It should be noted that if the base station 102A is implemented in the context of 5G NR, it may alternatively be referred to as a "gNodeB" or "gNB".

[0093] As shown, the base station 102A may also be configured to communicate with a network 100 (e.g., a core network of a cellular service provider, a telecommunication network such as a public switched telephone network (PSTN), and / or the Internet, among other possibilities). Thus, the base station 102A may facilitate communications between user devices and / or between user devices and the network 100. Specifically, the cellular base station 102A may provide the UE 106 / 107 with various telecommunication capabilities, such as voice, SMS, and / or data services.

[0094] Base station 102A and other similar base stations (such as base stations 102B, ..., 102N) operating according to the same or different cellular communication standards can therefore be provided as a network of cells that can provide continuous or nearly continuous overlapping service to UE 106A-106N and similar devices over a geographic area via one or more cellular communication standards.

[0095] Thus, although base station 102A may act as a "serving cell" for UE 106 / 107 as illustrated in FIG. 1 , each UE 106 / 107 may also be able to receive signals (and possibly be within communication range) from one or more other cells (which may be provided by base stations 102B to 102N and / or any other base station), which may be referred to as "neighboring cells". Such cells may also be able to facilitate communication between user devices and / or between user devices and network 100. Such cells may include "macro" cells, "micro" cells, "pico" cells, and / or cells of any various other granularity that provide service area sizes. For example, base stations 102A-102B illustrated in FIG. 1 may be macro cells, while base station 102N may be a micro cell. Other configurations are also possible.

[0096] In some embodiments, base station 102A may be a next generation base station, e.g., a 5G New Radio (5G NR) base station or "gNB". In some embodiments, a gNB may be connected to a legacy evolved packet core (EPC) network and / or to an NR core (NRC) network. In addition, a gNB cell may include one or more transition and reception points (TRPs). In addition, a UE capable of operating in accordance with 5G NR may be connected to one or more TRPs within one or more gNBs.

[0097] It should be noted that the UE 106 / 107 may be capable of communicating using multiple wireless communication standards. For example, the UE 106 / 107 may be configured to communicate using wireless networking (e.g., Wi-Fi) and / or peer-to-peer wireless communication protocols (e.g., Bluetooth, Wi-Fi peer-to-peer, etc.) in addition to at least one cellular communication protocol (e.g., GSM, UMTS (associated with, for example, WCDMA or TD-SCDMA air interfaces), LTE, LTE-A, 5G NR, HSPA, 3GPP2 CDMA2000 (e.g., 1xRTT, 1xEV-DO, HRPD, eHRPD), etc.). If desired, the UE 106 / 107 may also or alternatively be configured to communicate using one or more global navigation satellite systems (GNSS, such as GPS or GLONASS), one or more mobile television broadcast standards (e.g., ATSC-M / H or DVB-H), and / or any other wireless communication protocols. Other combinations of wireless communication standards (including more than two wireless communication standards) are also possible.

[0098] Note that the accessory device 107A / 107B may include cellular communication capabilities and thus be able to communicate directly with the cellular base station 102A via a cellular RAT. However, because the accessory device 107A / 107B may be one or more of communication, output power, and / or battery limited, the accessory device 107A / 107B may selectively utilize the UE 106A / 106B as a proxy for communication purposes with the base station 102A and, thereby, the network 100 in some instances. In other words, the accessory device 107A / 107B may selectively use the cellular communication capabilities of its companion device (e.g., UE 106A / 106B) for cellular communications. The limitation on the communication capabilities of the accessory device 107A / 107B may be permanent, such as due to limitations in output power or supported RATs, or temporary, such as due to various conditions such as current battery status, inability to access the network, or poor reception.

[0099] Figure 1BA user equipment 106 (e.g., one of devices 106A to 106N) and an accessory device (or user equipment) 107 (e.g., one of devices 107A or 107B) that communicate with a base station 102 and an access point 112 and with each other according to some embodiments are illustrated. UE 106 / 107 can be a device with cellular communication capabilities and non-cellular communication capabilities (e.g., Bluetooth, Wi-Fi, etc.), such as a mobile phone, a wearable device, a handheld device, a computer or tablet computer, or nearly any type of wireless device. Accessory device 107 can be a wearable device such as a smart watch. Accessory device 107 can include cellular communication capabilities and can communicate directly with base station 102 as shown. When accessory device 107 is configured to communicate directly with a base station, it can be said that the accessory device is in "autonomous mode". In addition, the accessory device 107 may also be able to communicate with another device (e.g., UE 106) (referred to as a proxy device, an intermediate device, or a companion device) using a short-range communication protocol; for example, according to some embodiments, the accessory device 107 may be "paired" with the UE 106, which may include establishing a communication channel and / or a trusted communication relationship with the UE 106. In some cases, the accessory device 107 may use the cellular functionality of the proxy device to communicate cellular voice and / or data with the base station 102. In other words, the accessory device 107 may provide voice and / or data packets intended for the base station 102 to the UE 106 via a short-range link, and the UE 106 may use its cellular functionality to send (or relay) the voice and / or data to the base station on behalf of the accessory device 107. Similarly, voice and / or data packets sent by the base station and intended for the accessory device 107 may be received by the cellular functionality of the UE 106 and may then be relayed to the accessory device via a short-range link. As described above, UE 106 can be a mobile phone, tablet or any other type of handheld device, a media player, a computer, a laptop, or virtually any type of wireless device. Note that when accessory device 107 is configured to communicate indirectly with base station 102 using the cellular functionality of an intermediate or proxy device, the accessory device can be said to be in "relay mode".

[0100] UE 106 / 107 may include a processor configured to execute program instructions stored in a memory. UE 106 / 107 may perform any of the method implementations described herein by executing such stored instructions. Alternatively or in addition, UE 106 / 107 may include a programmable hardware element, such as a field programmable gate array (FPGA) configured to perform any of the method implementations described herein or any part of any of the method implementations described herein.

[0101] UE 106 / 107 may include one or more antennas for communicating using one or more wireless communication protocols or technologies. In some embodiments, UE 106 may be configured to communicate using, for example, CDMA2000 (1xRTT / 1xEV-DO / HRPD / eHRPD), LTE / Advanced LTE, or 5G NR using a single shared radio component and / or GSM, LTE, Advanced LTE, or 5G NR using a single shared radio component. The shared radio component may be coupled to a single antenna, or may be coupled to multiple antennas (e.g., for MIMO) for performing wireless communications. Typically, the radio component may include any combination of a baseband processor, an analog RF signal processing circuit (e.g., including filters, mixers, oscillators, amplifiers, etc.) or a digital processing circuit (e.g., for digital modulation and other digital processing). Similarly, the radio component may use the aforementioned hardware to implement one or more receive chains and transmit chains. For example, UE 106 / 107 may share one or more parts of a receive chain and / or a transmit chain between multiple wireless communication technologies such as those discussed above.

[0102] In some embodiments, UE 106 / 107 may include a separate transmit chain and / or receive chain (e.g., including separate antennas and other radio components) for each wireless communication protocol configured to communicate with it. As another possibility, UE 106 / 107 may include one or more radio components shared between multiple wireless communication protocols, and one or more radio components used uniquely by a single wireless communication protocol. For example, UE 106 / 107 may include a shared radio component for communicating using either LTE or 5G NR (or LTE or 1xRTT, or LTE or GSM), and a separate radio component for communicating using each of Wi-Fi and Bluetooth. Other configurations are also possible.

[0105] The base station 102 may include at least one network port 270. The network port 270 may be configured to couple to a telephone network and provide access to multiple devices (such as the UE device 106) as described above in FIG. Figure 2 Access to the telephone network described in.

[0106] The network port 270 (or an additional network port) may also be configured or alternatively configured to couple to a cellular network, such as a core network of a cellular service provider. The core network may provide mobility-related services and / or other services to a plurality of devices, such as the UE device 106. In some cases, the network port 270 may be coupled to a telephone network via the core network, and / or the core network may provide a telephone network (e.g., in other UE devices served by a cellular service provider).

[0107] In some embodiments, base station 102 may be a next generation base station, such as a 5G New Radio (5G NR) base station, or "gNB". In such embodiments, base station 102 may be connected to a legacy evolved packet core (EPC) network and / or to an NR core (NRC) network.

[0108] The base station 102 may include at least one antenna 234 and possibly multiple antennas. The at least one antenna 234 may be configured to operate as a wireless transceiver and may be further configured to communicate with the UE device 106 via the radio component 230.

The radio component 230 may be configured to communicate via various wireless communication standards, including but not limited to 5G NR, LTE, LTE-A, GSM, UMTS, CDMA2000, Wi-Fi, etc.

[0109] Base station 102 may be configured to perform wireless communications using multiple wireless communication standards. In some instances, base station 102 may include multiple radio components that enable base station 102 to communicate according to multiple wireless communication technologies. For example, as one possibility, base station 102 may include an LTE radio component for performing communications according to LTE and a 5G NR radio component for performing communications according to 5GNR. In this case, base station 102 may be able to operate as both an LTE base station and a 5G NR base station. As another possibility, base station 102 may include a multimode radio component capable of performing communications according to any one of a plurality of wireless communication technologies (e.g., 5G NR and Wi-Fi, LTE and Wi-Fi, LTE and UMTS, LTE and CDMA2000, UMTS and GSM, etc.).

[0119] Figure 4 :UE block diagram

[0120] Figure 4 An example simplified block diagram of a communication device 106 / 107 according to some embodiments is illustrated. Note that Figure 4 The block diagram of the communication device is only an example of a possible communication device. According to the embodiment, the communication device 106 / 107 can be a user equipment (UE) device, a mobile device or a mobile station, a wireless device or a wireless station, a desktop computer or a computing device, a mobile computing device (e.g., a laptop, a notebook or a portable computing device), a wearable device, a tablet computer, an unmanned aerial vehicle (UAV), a UAV controller (UAC) and / or a combination of devices and other devices. As shown in the figure, the communication device 106 / 107 may include a group of components 400 configured to perform core functions. For example, the group of components may be implemented as a system on a chip (SOC), which may include parts for various purposes. Alternatively, the group of components 400 may be implemented as a separate component or a group of components for various purposes. This group of components 400 may be (e.g., communicatively; directly or indirectly) coupled to various other circuits of the communication device 106.

[0121] For example, the communication device 106 / 107 may include various types of memory (e.g., including NAND flash memory 410), input / output interfaces such as connector I / F 420 (e.g., for connecting to a computer system; a docking station; a charging station; input devices such as microphones, cameras, keyboards; output devices such as speakers; etc.), a display 460 (which may be integrated with the communication device 106 / 107 or external thereto), and wireless communication circuitry 430. The wireless communication circuitry 430 may include a cellular modem 434 such as for 5G NR, LTE, GSM, etc., and a short-range to mid-range wireless communication logic component 436 (e.g., Bluetooth TM In some embodiments, the communication devices 106 / 107 may include wired communication circuitry (not shown), such as, for example, a network interface card for Ethernet.

[0122] The wireless communication circuit 430 may be (e.g., communicatively; directly or indirectly) coupled to one or more antennas, such as antennas 435a, 435b, and 435c (e.g., 435a to 435c) as shown. The wireless communication circuit 430 may include a local area network (LAN) logic component 432, a cellular modem 434, and / or a short-range communication logic component 436. The LAN logic component 432 may be used to enable the UE device 106 / 107 to perform LAN communications, such as Wi-Fi communications on an 802.11 network, and / or other WLAN communications. The short-range communication logic component 436 may be used to enable the UE device 106 / 107 to perform communications according to a short-range RAT, such as Bluetooth or UWB communications. In some scenarios, the cellular modem 434 may be a lower power cellular modem capable of performing cellular communications according to one or more cellular communication technologies.

[0123] In some embodiments, as further described below, the cellular modem 434 can include dedicated receive chains (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components) for multiple RATs (e.g., a first receive chain for LTE and a second receive chain for 5G NR). In addition, in some embodiments, the cellular modem 434 can include a single transmit chain that can switch between radio components dedicated to specific RATs. For example, a first radio component can be dedicated to a first RAT, such as LTE, and can communicate with the dedicated receive chain and a transmit chain shared with additional radio components, such as a second radio component that can be dedicated to a second RAT (e.g., 5G NR) and can communicate with the dedicated receive chain and the shared transmit chain.

[0124] Communication device 106 / 107 may also include one or more user interface elements and / or be configured for use with one or more user interface elements. User interface elements may include any of various elements, such as display 460 (which may be a touch screen display), keyboard (which may be a separate keyboard or may be implemented as a part of a touch screen display), mouse, microphone and / or loudspeaker, one or more cameras, one or more buttons, and / or any of various other elements capable of providing information to a user and / or receiving or interpreting user input.

[0125] The communication device 106 / 107 may also include one or more smart cards 445 with SIM (Subscriber Identity Module) functionality, such as one or more UICC (Universal Integrated Circuit Card) cards 445. Note that the term "SIM" or "SIM entity" is intended to include any of various types of SIM implementations or SIM functions, such as one or more UICC cards 445, one or more eUICCs, one or more eSIMs, removable or embedded, etc. In some embodiments, the UE 106 / 107 may include at least two SIMs. Each SIM may execute one or more SIM applications and / or implement SIM functions in other ways. Thus, each SIM may be a single smart card that may be embedded, for example, soldered to a circuit board in the UE 106 / 107, or each SIM 410 may be implemented as a removable smart card. Thus, the SIM may be one or more removable smart cards (such as a UICC card, sometimes referred to as a "SIM card"), and / or the SIM 410 may be one or more embedded cards (such as an embedded UICC (eUICC), sometimes referred to as an "eSIM" or "eSIM card"). In some embodiments (such as when the SIM includes an eUICC), one or more of the SIMs may implement embedded SIM (eSIM) functionality; in such embodiments, a single SIM in the SIM may execute multiple SIM applications. Each SIM may include components such as a processor and / or a memory; instructions for performing SIM / eSIM functionality may be stored in the memory and executed by the processor. In some embodiments, the UE 106 / 107 may include a combination of removable smart cards and fixed / non-removable smart cards (such as one or more eUICC cards that implement eSIM functionality) as needed. For example, the UE 106 / 107 may include two embedded SIMs, two removable SIMs, or a combination of one embedded SIM and one removable SIM. Various other SIM configurations are also contemplated.

[0126] As described above, in some embodiments, UE 106 / 107 may include two or more SIMs. Including two or more SIMs in UE 106 / 107 may allow UE 106 / 107 to support two different phone numbers, and may allow UE 106 / 107 to communicate on corresponding two or more corresponding networks. For example, a first SIM may support a first RAT such as LTE, and a second SIM 410 may support a second RAT such as 5G NR. Of course, other specific implementations and RATs are also possible. In some embodiments, when UE 106 / 107 includes two SIMs, UE 106 / 107 may support dual card dual communication (DSDA) functionality. The DSDA functionality may allow UE 106 / 107 to be connected to two networks (and use two different RATs) at the same time, or to allow two connections supported by two different SIMs using the same or different RATs to be maintained simultaneously on the same or different networks. The DSDA functionality may also allow UE 106 / 107 to receive voice calls or data traffic simultaneously on any phone number. In some embodiments, voice calls may be packet-switched communications. In other words, voice calls may be received using voice over LTE (VoLTE) technology and / or voice over NR (VoNR) technology. In some embodiments, UE 106 / 107 may support dual SIM dual standby (DSDS) functionality. The DSDS functionality may allow either of the two SIMs in UE 106 / 107 to standby for voice calls and / or data connections. In DSDS, when a call / data is established on one SIM, the other SIM is no longer active. In some embodiments, the DSDx functionality (DSDA or DSDS functionality) may be implemented using a single SIM (e.g., eUICC) that executes multiple SIM applications for different carriers and / or RATs.

[0127] As shown, SOC 400 may include a processor 402 that may execute program instructions for communication device 106 and a display circuit 404 that may perform graphics processing and provide display signals to display 460. Processor 402 may also be coupled to a memory management unit (MMU) 440 (which may be configured to receive addresses from processor 402 and translate those addresses into locations in memory (e.g., memory 406, read-only memory (ROM) 450, NAND flash memory 410), and / or to other circuits or devices (such as display circuit 404, short-range to mid-range wireless communication circuit 429, cellular communication circuit 430, connector I / F 420, and / or display 460). MMU 440 may be configured to perform memory protection and page table translation or setup. In some embodiments, MMU 440 may be included as part of processor 402.

[0128] As described above, the communication device 106 may be configured to communicate using wireless and / or wired communication circuits. The communication device 106 may be configured to perform methods for MAC behavior and RRC configuration for UL WUS of connected UEs, such as in 5G NR systems and higher, as further described herein.

[0129] As described herein, the communication device 106 / 107 may include hardware components and software components for implementing the above-mentioned features of the communication device 106 / 107 to communicate the scheduling profile for power saving to the network. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processor 402 of the communication device 106 / 107 can be configured to implement part or all of the features described herein. Alternatively (or additionally), the processor 402 can be configured as a programmable hardware element, such as an FPGA (field programmable gate array) or an ASIC (application-specific integrated circuit). Alternatively (or additionally), in combination with one or more other components in other components 400, 404, 406, 410, 420, 429, 430, 440, 445, 450, 460, the processor 402 of the communication device 106 can be configured to implement part or all of the features described herein.

[0130] Additionally, as described herein, processor 402 may include one or more processing elements. Thus, processor 402 may include one or more integrated circuits (ICs) configured to perform the functions of processor 402. Additionally, each integrated circuit may include circuits (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processor 402.

[0131] In addition, as described herein, the cellular communication circuit 430 and the short-range to medium-range wireless communication circuit 429 may each include one or more processing elements. In other words, one or more processing elements may be included in the cellular communication circuit 430, and similarly, one or more processing elements may be included in the short-range to medium-range wireless communication circuit 429. Therefore, the cellular communication circuit 430 may include one or more integrated circuits (ICs) configured to perform the functions of the cellular communication circuit 430. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the cellular communication circuit 430. Similarly, the short-range to medium-range wireless communication circuit 429 may include one or more ICs configured to perform the functions of the short-range to medium-range wireless communication circuit 429. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the short-range to medium-range wireless communication circuit 429.

[0132] Figure 5: Block diagram of a cellular communication circuit

[0133] Figure 5 An example simplified block diagram of a cellular communication circuit according to some embodiments is illustrated. Note that Figure 5 The block diagram of the cellular communication circuit of is only one example of possible cellular communication circuits. According to an embodiment, the cellular communication circuit 530 (which may be the cellular modem circuit 434) may be included in a communication device such as the communication device 106 / 107 described above. As described above, the communication device 106 / 107 may be a user equipment (UE) device, a mobile device or mobile station, a wireless device or wireless station, a desktop computer or computing device, a mobile computing device (e.g., a laptop, notebook, or portable computing device), a tablet computer, a wearable device, and / or a combination of devices, among other devices.

[0134] Cellular communication circuitry 530 may be coupled (eg, communicatively; directly or indirectly) to one or more antennas, such as antennas 535a through 535c (which may be Figure 4 In some embodiments, the cellular communication circuit 530 may include dedicated receive chains (including and / or coupled to (e.g., communicatively; directly or indirectly) dedicated processors and / or radio components) for multiple RATs (e.g., a first receive chain for LTE and a second receive chain for 5G NR). For example, Figure 5 As shown, the cellular communication circuit 530 may include a modem 510 and a modem 520. The modem 510 may be configured for communication according to a first RAT (e.g., such as LTE or LTE-A), and the modem 520 may be configured for communication according to a second RAT (e.g., such as 5G NR).

[0135] As shown, the modem 510 may include one or more processors 512 and a memory 516 in communication with the processor 512. The modem 510 may communicate with a radio frequency (RF) front end 530. The RF front end 530 may include circuits for sending and receiving radio signals. For example, the RF front end 530 may include a receiving circuit (RX) 532 and a transmitting circuit (TX) 534. In some embodiments, the receiving circuit 532 may communicate with a downlink (DL) front end 550, which may include circuits for receiving radio signals via an antenna 535a.

[0136] Similarly, the modem 520 may include one or more processors 522 and a memory 526 in communication with the processor 522. The modem 520 may communicate with the RF front end 540. The RF front end 540 may include circuits for sending and receiving radio signals. For example, the RF front end 540 may include a receiving circuit 542 and a transmitting circuit 544. In some embodiments, the receiving circuit 542 may communicate with the DL front end 560, which may include circuits for receiving radio signals via the antenna 535b.

[0137] In some embodiments, the switch 570 may couple the transmit circuit 534 to an uplink (UL) front end 572. Additionally, the switch 570 may couple the transmit circuit 544 to the UL front end 572. The UL front end 572 may include circuitry for transmitting radio signals via the antenna 535c. Thus, when the cellular communication circuit 530 receives an instruction to transmit according to a first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572) supported by the modem 510, the switch 570 may be switched to a first state that allows the modem 510 to transmit signals according to the first RAT (e.g., via a transmit chain including the transmit circuit 534 and the UL front end 572). Similarly, when the cellular communication circuit 530 receives an instruction to transmit according to a second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572) supported by the modem 520, the switch 570 may be switched to a second state that allows the modem 520 to transmit signals according to the second RAT (e.g., via a transmit chain including the transmit circuit 544 and the UL front end 572).

[0138] In some embodiments, the cellular communication circuit 530 may be configured to perform methods for MAC behavior and RRC configuration for UL WUS of connected UEs, for example in 5G NR systems and above, as further described herein.

[0139] As described herein, the modem 510 may include hardware components and software components for implementing the above-described features or for time-division multiplexing UL data for NSA NR operations and various other technologies described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processor 512 may be configured to implement some or all of the features described herein. Alternatively (or in addition), the processor 512 may be configured as a programmable hardware element such as an FPGA (field programmable gate array), or as an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more of the other components 530, 532, 534, 550, 570, 572, 535a to 535c, the processor 512 may be configured to implement some or all of the features described herein.

[0140] In addition, as described herein, processor 512 may include one or more processing elements. Thus, processor 512 may include one or more integrated circuits (ICs) configured to perform the functions of processor 512. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of processor 512.

[0141] As described herein, the modem 520 may include hardware components and software components for implementing the above-described features for MAC behavior and RRC configuration of UL WUS for connected UEs, for example, in 5G NR systems and higher versions, as well as various other technologies described herein. For example, by executing program instructions stored on a memory medium (e.g., a non-transitory computer-readable memory medium), the processor 522 may be configured to implement part or all of the feature parts described herein. Alternatively (or in addition), the processor 522 may be configured as a programmable hardware element such as an FPGA (field programmable gate array), or as an ASIC (application-specific integrated circuit). Alternatively (or in addition), in combination with one or more of the other components 540, 542, 544, 550, 570, 572, 535a to 535c, the processor 522 may be configured to implement part or all of the features described herein.

[0142] In addition, as described herein, the processor 522 may include one or more processing elements. Thus, the processor 522 may include one or more integrated circuits (ICs) configured to perform the functions of the processor 522. In addition, each integrated circuit may include a circuit (e.g., a first circuit, a second circuit, etc.) configured to perform the functions of the processor 522.

[0143] Fig. 6A , Figure 6B and Figure 7 : 5G core network architecture—interworking with Wi-Fi

[0144] In some embodiments, the 5G core network (CN) can be accessed via (or through) a cellular connection / interface (e.g., via a 3GPP communication architecture / protocol) and a non-cellular connection / interface (e.g., a non-3GPP access architecture / protocol such as a Wi-Fi connection). Fig. 6AAn example of a 5G network architecture according to some embodiments is illustrated, which combines both 3GPP (e.g., cellular) and non-3GPP (e.g., non-cellular) access to 5G CN. As shown, a user equipment device (e.g., such as UE 106) can access 5G CN through both a radio access network (RAN, such as gNB 604, which can be a base station 102) and an access point (such as AP 612). AP 612 may include a connection to the Internet 600 and a connection to a non-3GPP interworking function (N3IWF) 603 network entity. N3IWF may include a connection to a core access and mobility management function (AMF) 605 of the 5G CN. AMF 605 may include an instance of a 5G mobility management (5G MM) function associated with UE 106 / 107. In addition, RAN (e.g., gNB 604) may also have a connection to AMF 605. Thus, the 5G CN may support unified authentication on both connections and allow simultaneous registration of UE 106 / 107 access via both gNB 604 and AP 612. As shown, the AMF 605 may communicate with a location management function (LMF) 609 via a network interface such as an NL interface. The LMF 609 may receive measurement and assistance information from the RAN (e.g., gNB 604) and the UE (e.g., UE 106) via the AMF 605. The LMF 609 may be a server (e.g., server 104) and / or a functional entity executed on the server. In addition, based on the measurement and / or assistance information received from the RAN and the UE, the LMF may determine the location of the UE. In addition, the AMF 605 may include one or more functional entities associated with the 5G CN (e.g., a network slice selection function (NSSF) 620, a short message service function (SMSF) 622, an application function (AF) 624, a unified data management (UDM) 626, a policy control function (PCF) 628, and / or an authentication server function (AUSF) 630). It should be noted that these functional entities may also be supported by the session management function (SMF) 606a and SMF 606b of the 5G CN. The AMF 605 may be connected to (or communicate with) the SMF 606a. In addition, the gNB 604 may communicate with (or be connected to) a user plane function (UPF) 608a, which may also communicate with the SMF 606a. Similarly, the N3IWF 603 may communicate with the UPF 608b, which may also communicate with the SMF 606b. Both UPFs may communicate with a data network (eg, DNs 610a and 610b) and / or the Internet 600 and an Internet Protocol (IP) Multimedia Subsystem / IP Multimedia Core Subsystem (IMS) Core Network 610.

[0145] Figure 6B An example of a 5G network architecture according to some embodiments is illustrated, which combines both dual 3GPP (e.g., LTE and 5G NR) and non-3GPP access to 5GCN. As shown, a user equipment device (e.g., such as UE106) can access 5G CN through a radio access network (RAN, such as gNB 604 or eNB 602, which can be a base station 102) and an access point (such as AP 612). AP 612 may include a connection to the Internet 600 and a connection to the N3IWF 603 network entity. N3IWF may include a connection to AMF 605 of 5G CN. AMF 605 may include an instance of a 5G MM function associated with UE 106 / 107. In addition, RAN (e.g., gNB 604) may also have a connection to AMF 605. Thus, the 5G CN may support unified authentication on both connections and allow simultaneous registration of UE 106 / 107 access via both gNB 604 and AP 612. In addition, the 5G CN may support dual registration of UEs on both legacy networks (e.g., LTE via eNB 602) and 5G networks (e.g., via gNB 604). As shown, the eNB 602 may have connections to a mobility management entity (MME) 642 and a serving gateway (SGW) 644. The MME 642 may have connections to both the SGW 644 and the AMF 605. In addition, the SGW 644 may have connections to both the SMF 606a and the UPF 608a. As shown, the AMF 605 may communicate with the LMF 609 via, for example, a network interface (such as NL) as described above and may include one or more functional entities associated with the 5G CN (e.g., NSSF 620, SMSF 622, AF 624, UDM 626, PCF 628, and / or AUSF 630). Note that the UDM 626 may also include a Home Subscriber Server (HSS) function, and the PCF may also include a Policy and Charging Rules Function (PCRF). Note also that these functional entities may also be supported by the SMF 606a and SMF 606b of the 5GCN. The AMF 606 may be connected to (or in communication with) the SMF 606a. In addition, the gNB 604 may communicate with (or be connected to) the UPF 608a, which may also communicate with the SMF 606a. Similarly, N3IWF 603 can communicate with UPF 608b, which can also communicate with SMF 606b. Both UPFs can communicate with data networks (e.g., DN 610a and 610b) and / or the Internet 600 and IMS core network 610.

[0146] Note that in various embodiments, one or more of the above-mentioned network entities may be configured to perform methods for MAC behavior and RRC configuration for UL WUS of connected UEs, for example in 5G NR systems and higher, for example, as further described herein.

[0147] Figure 7 An example of a baseband processor architecture for a UE (eg, such as UE 106) according to some embodiments is illustrated. Figure 7 The baseband processor architecture 700 described in the figure can be implemented on one or more radio components (e.g., the radio components 429 and / or 430 described above) or modems (e.g., modems 510 and / or 520) as described above. As shown in the figure, the non-access layer (NAS) 710 may include a 5G NAS 720 and a traditional NAS 750. The traditional NAS 750 may include a communication connection with a traditional access layer (AS) 770. The 5G NAS 720 may include a communication connection with a 5G AS 740 and a non-3GPP AS 730 and a Wi-Fi AS 732. The 5G NAS 720 may include functional entities associated with two access layers. Therefore, the 5G NAS720 may include multiple 5G MM entities 726 and 728 and 5G session management (SM) entities 722 and 724. The legacy NAS 750 may include functional entities such as a short message service (SMS) entity 752, an evolved packet system (EPS) session management (ESM) entity 754, a session management (SM) entity 756, an EPS mobility management (EMM) entity 758, and a mobility management (MM) / GPRS mobility management (GMM) entity 760. In addition, the legacy AS 770 may include functional entities such as an LTE AS 772, a UMTS AS 774, and / or a GSM / GPRS AS 776.

[0148] Thus, the baseband processor architecture 700 allows for a common 5G-NAS for both 5G cellular and non-cellular (e.g., non-3GPP access). Note that, as shown, 5G MM can maintain a separate connection management and registration management state machine for each connection. In addition, a device (e.g., UE 106) can register to a single PLMN (e.g., 5G CN) using 5G cellular access as well as non-cellular access. In addition, a device can be in a connected state in one access and in an idle state in another access, or vice versa. Finally, there may be common 5G-MM processes (e.g., registration, deregistration, identification, authentication, etc.) for both accesses.

[0149] It should be noted that in various embodiments, one or more of the above-mentioned functional entities of the 5G NAS and / or 5G AS may be configured to perform methods for MAC behavior and RRC configuration for UL WUS of connected UEs, for example in 5G NR systems and higher versions, for example, as further described herein.

[0150] MAC behavior and RRC configuration for UL WUS of connected UEs

[0151] 3GPP Release 18 aims to provide opportunities for network energy saving. Technologies for improving network energy saving in terms of both base station transmission and reception on both the network and UE sides are currently being studied. For example, how to utilize potential support / feedback from the UE and potential UE assistance information in one or more network energy saving technologies to dynamically and / or semi-statically achieve more efficient operation and achieve finer-grained adaptation of transmission and / or reception in the time domain, frequency domain, spatial domain and power domain. As another example, how to exchange and / or coordinate information related to network energy saving through a network interface. Note that idle / empty and / or low / medium load scenarios are prioritized.

[0152] One proposed concept introduces a cell discontinuous reception cycle (DRX) / discontinuous transmission (DTX) cycle and an uplink (UL) wake-up signal (WUS). In cell DRX, the base station may enter a sleep mode / state (e.g., "gNB sleep mode / state") during the DRX / DTX off duration. During the sleep mode / state, the base station may not transmit and / or receive at least a portion of the signal / channel, e.g., Figure 8 As illustrated. In some scenarios, it has been proposed that periodic on / off periods can be configured in the system information block (SIB). In addition, different base station sleep modes may indicate different levels of base station transmit / receive behavior during the DRX / DRX off duration. For example, sleep mode 0 may correspond to legacy base station operation without energy saving, and sleep mode 1 may correspond to no reference signal transmission (e.g., SSB, CSI-RS, TRS, etc.), no downlink (DL) data transmission, and no UL reception (e.g., including UL grant, configured grant (CG) PUSCH, RACH, SR, and / or SRS). In other words, in sleep mode 1, the base station may turn off its RF and power amplifier (PA). In sleep mode 2, only SSB transmission may be allowed, and there may be no DL data transmission or UL reception.

[0153] In addition, the UL WUS can be a layer 1 (L1) UL signal from the UE to the base station for notifying the base station to wake up from a sleep mode / state. However, the RRC configuration and MAC behavior of the UL WUS have not yet been determined. Therefore, it is necessary to consider the impact of base station blind detection on network energy saving. For example, the base station may need to perform blind detection on uncertain UL transmissions with periodic resources (e.g., such as RACH, SR, and CG-PUSCH), which is a major contributor to base station power consumption. In addition, due to blind detection, the detection of HARQ-ACK / CSI (e.g., in PUCCH) is another major contributor to base station power consumption (although the base station generally knows when to expect these in the UL, for example, the base station may only expect UCI on certain carriers or certain PUCCH groups may be deactivated). In addition, although the base station will not transmit UL / DL grants to the UE during the cell DRX / DTX off period, the UE may have the above-mentioned UL transmission with periodic resources (e.g., such as RACH and CG with high priority services), so the base station needs to know whether it needs to wake up during the DRX / DTX off period for reception in one or some of the periodic resources.

[0154] The embodiments described herein provide systems, methods, and mechanisms for MAC behavior and RRC configuration of UL WUS for a connected UE, including systems, methods, and mechanisms for configuring resources for the UE to transmit UL WUS, configuring trigger conditions for sending UL WUS signals after receiving UL WUS, UE behavior for sending UL WUS, and base station behavior.

[0155] In some instances, periodic UL resources (e.g., periodicity and slot offset) similar to scheduling request (SR) resources may be configured. In some instances, periodic UL resources with different patterns (e.g., periodicity and slot offset) may be configured in the cell DRX / DTX on duration and the cell DRX / DTX off duration. Note that the resources in the cell DRX / DTX off duration may be sparser (e.g., less frequent) than the resources in the cell DRX / DTX on duration. In some instances, UL resources for x slots before the start time of the cell DRX / DTX off duration may be configured. Note that the value of x may be configured via a system information block (SIB) and / or via radio resource control (RRC) signaling. In some instances, non-periodic UL resources may be triggered by a base station. The trigger signaling may be UE-specific downlink control information (DCI) (e.g., such as DCI 1-1) or UE common DCI (e.g., such as DCI 2-7) for connected UEs. The trigger signal may also be a MAC control element (CE) for activating a specific mode for WUS triggering (e.g., based on information in a MAC CE). Note that if a timing advance (TA) timer expires, the UE may release the resource. In some instances, the UL WUS resources may be shared with a group of UEs or may be UE-specific. In some instances, a prohibit timer and a maximum number of transmissions may be configured for each UL WUS resource.

[0156] In some instances, the UL WUS resources may be configured to be associated with 0, 1 or more logical channels. In some instances, the UL WUS resources may be configured to be associated with one or more upcoming configuration grant (CG) physical uplink shared channel (PUSCH) resources. In some instances, the UL WUS resources may be configured to be associated with one or more upcoming random access channel (RACH) resources. In some instances, the UL WUS resources may be configured to be associated with an upcoming cell DRX / DTX off duration. In some instances, the UL WUS resources may be configured to be associated with any combination of the above resources. Note that the UL WUS resources may be configured as per UE configuration and / or per base station sleep mode / state configuration.

[0157] In some instances, the trigger condition may be configured in the SIB and / or via RRC signaling. In some instances, the minimum logical channel (LCH) priority threshold of the associated CG-PUSCH resource may be configured, for example, via SIB and RRC signaling, trigger conditions. Note that the LCH priority threshold may be per UE or per base station sleep mode / state. In some instances, as a trigger condition, RACH may be triggered for the associated RACH resource. In some instances, if the UE transmits a UL WUS just before the cell DRX / DTX off duration, the minimum LCH priority threshold of the associated CG-PUSCH or RACH may be used as a trigger condition. In some instances, the minimum physical channel priority threshold of the associated dynamic grant (DG) PUSCH may be used as a trigger condition.

[0158] In some examples, after detecting the triggering condition for sending the UL WUS, the MAC layer of the UE may check, determine and / or confirm whether the conditions for transmitting (sending) the UL WUS are met, for example, Fig. 9 exemplified.

[0159] Fig. 9 A block diagram illustrating an example of a method for a UE to confirm whether a condition for transmitting a UL WUS is met according to some embodiments. Fig. 9 The method shown can also be used in combination with any one of the systems, methods or devices shown in the figure. In various embodiments, some method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as required. As shown in the figure, the method can operate as follows.

[0160] At 902, the MAC layer of a UE (such as UE 106) may detect a trigger condition for transmission of a UL WUS. At 904, the MAC layer of the UE may check, determine, and / or confirm that the prohibition timer is not running at the time of the UL WUS transmission opportunity. At 906, the MAC layer of the UE may check, determine, and / or confirm that the UL WUS transmission opportunity does not overlap with the measurement gap. At 908, after confirming that the conditions for transmitting (sending) the UL WUS are met, the MAC layer of the UE may determine whether the number of transmissions is less than the configured maximum number of transmissions. At 910, after determining that the number of transmissions is less than the configured maximum number of transmissions, the MAC layer of the UE may instruct the lower layer of the UE to transmit (send) the UL WUS and reset the prohibition timer. Otherwise, at 912, after confirming that the conditions for transmitting (sending) the UL WUS are not met and / or after determining that the number of transmissions is not less than the configured maximum number of transmissions, the MAC layer of the UE may notify the higher layer of the UE (e.g., such as the RRC layer) of the failure to transmit (send) the UL WUS.

[0161] In some instances, for example, depending on the sequence design of the UL WUS signal, the UL WUS signal may carry and / or include information such as: an indication of whether the UE intends to transmit RACH and / or CG-PUSCH in upcoming UL resources, an indication of which upcoming CG-PUSCH resource the UE intends to use, an indication of which upcoming RACH resource the UE intends to use, and / or an indication that the UE intends to send in an upcoming cell DRX / DTX off duration.

[0162] In some instances, the UE may be configured with multiple UL WUS configurations corresponding to different resources. In such instances, the UE may select a UL WUS resource to implicitly indicate whether the UE intends to transmit RACH and / or CG-PUSCH in an upcoming UL resource, which upcoming CG-PUSCH resource the UE intends to use, which upcoming RACH resource the UE intends to use, and / or the UE intends to transmit in an upcoming cell DRX / DTX off duration. For example, when the UE intends to use a first CG-PUSCH resource, the UE may send a UL WUS in the first resource. As another example, when the UE intends to use a second CG-PUSCH resource, the UE may send a UL WUS in the second resource.

[0163] In some instances, upon receiving the UL WUS signal, the base station may respond to a specific UE (e.g., only if the UL WUS resource is a UE-specific configuration), or may respond to multiple UEs' decisions on whether to wake up in one or some upcoming UL resources. The response signaling may be a DCI or a MAC-CE or an associated RS (e.g., the UE may detect a base station sleep model associated with the RS (or sleep mode signal)). In some instances, the base station may reject the UL WUS and request the UE to repeat the UL WUS after a predefined time. In some instances, when the base station indicates that it will wake up in one or more upcoming UL resources, the UE (or multiple UEs) receiving the response signaling (e.g., an indication that the base station will wake up) may transmit (send) pending RACH and / or PUSCH in the indicated UL resources. Alternatively, when the base station indicates that it will not wake up in one or more upcoming UL resources, the UE (or multiple UEs) receiving the response signaling (e.g., an indication that the base station will not wake up) may suspend pending RACH and / or PUSCH in the indicated UL resources. In some examples, when the base station does not provide a response to the UL WUS and the associated UL resources are in the cell DRX / DTX on duration, the UE (or multiple UEs) may transmit (send) pending RACH and / or PUSCH in the associated UL resources. However, when the base station does not provide a response to the UL WUS and the associated UL resources are in the cell DRX / DTX off duration, the UE (or multiple UEs) may suspend pending RACH and / or PUSCH in the associated UL resources.

[0164] Fig.10 A block diagram illustrating an example of a method for UE behavior based on a wake-up indication from a base station according to some embodiments. In addition to other devices, Fig.10 The method shown can also be used in combination with any one of the systems, methods or devices shown in the figure. In various embodiments, some method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as required. As shown in the figure, the method can operate as follows.

[0165] At 1002, a base station (such as base station 102) may determine whether to wake up in one or more upcoming UL resources. At 1004, in response to the base station determining that the base station will wake up in one or more upcoming UL resources, a UE (such as UE 106) and / or a group of UEs may receive an indication from the base station that the base station will wake up in one or more upcoming UL resources. At 1006, the UE (or multiple UEs) receiving the indication that the base station will wake up may transmit a pending RACH and / or PUSCH to the base station in the indicated UL resources. Alternatively, at 1008, in response to the base station determining that the base station will not wake up in one or more upcoming UL resources, the UE (such as UE 106) and / or a group of UEs may receive an indication from the base station that the base station will not wake up in one or more upcoming UL resources. At 1010, the UE (or multiple UEs) receiving the indication that the base station will not wake up may suspend the pending RACH and / or PUSCH in the indicated UL resources.

[0166] Fig.11 A block diagram illustrating an example of a method for base station behavior upon receiving an UL wake-up signal according to some embodiments. Fig.11 The method shown can also be used in combination with any one of the systems, methods or devices shown in the figure. In various embodiments, some method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as required. As shown in the figure, the method can operate as follows.

[0167] At 1102, a base station (such as base station 102) may receive a UL WUS from a UE (such as UE 106) and / or a group of UEs. At 1104, the base station may determine whether to wake up in one or more upcoming UL resources. At 1106, for example, in response to determining that the base station will wake up in one or more upcoming UL resources, the base station may determine whether to transmit an indication that the base station will wake up in one or more upcoming resources. At 1108, the base station may receive a pending RACH and / or PUSCH in the indicated UL resource from the UE (or multiple UEs) that received the indication that the base station will wake up. Alternatively, at 1110, the base station may determine whether one or more upcoming UL resources are in a cell DRX / DTX on duration. At 1112, for example, when it is determined that one or more upcoming UL resources appear in the cell DRX / DTX on duration, the base station may receive a pending RACH and / or PUSCH from the UE (or multiple UEs) in one or more upcoming UL resources. Alternatively, at 1114, the base station may not wake up, for example, when the upcoming one or more UL resources are in the cell DRX / DTX off duration. In such an example, the UE (or multiple UEs) may suspend pending RACH and / or PUSCH in the one or more upcoming UL resources.

[0168] Fig.12 A block diagram illustrating an example of a method for configuring an uplink (UL) wake-up signal (WUS) according to some embodiments. Among other devices, Fig.12 The method shown can be used in combination with any one of the systems, methods or devices shown in the figure. In various embodiments, some of the method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as needed. As shown in the figure, the method can operate as follows.

[0169] At 1202, a UE (such as UE 106) may receive an indication of resources for a UL WUS from a base station (such as base station 102). In some instances, the indication may include a prohibition timer and a maximum number of transmissions per UL WUS resource. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more logical channels. In some instances, the indication may specify that the resources for the UL WUS are not associated with any logical channel. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more upcoming configuration grant (CG) physical uplink shared channel (PUSCH) resources. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more upcoming random access channel (RACH) resources. In some instances, the indication may specify that the resources for the UL WUS are associated with an upcoming cell DRX / DTX off duration. In some instances, the indication may specify that the resources for the UL WUS are configured as per UE configuration or per base station sleep mode / state configuration.

[0170] In some instances, the resource for the UL WUS may be a periodic UL resource. The indication may specify the periodicity of the periodic UL resource and the time slot offset of the periodic UL resource. The indication may specify a first configuration of the periodic UL resource for a cell discontinuous reception cycle (DRX) / discontinuous transmission cycle (DTX) on duration and a second configuration of the periodic UL resource for a cell DRX / DTX off duration. In some instances, the first configuration may specify a denser resource than the second configuration.

[0171] In some examples, the indication may specify UL resources for a number of time slots prior to the start time of the cell DRX / DTX off duration. The number of time slots may be specified via a system information block or radio resource control signaling.

[0172] In some instances, the resource for the UL WUS may be an aperiodic UL resource. The aperiodic UL resource may be triggered via signaling from the base station. The signaling may include one of UE common downlink control information (DCI), UE dedicated DCI, or medium access control (MAC) control element (CE). The UE common DCI may be DCI 2-7, for example, DCI format 2_7. The UE dedicated DCI may be DCI 1-1 and / or a paging short message. The MAC CE may activate a specific mode for UL WUS triggering.

[0173] At 1204, the UE may receive one or more trigger conditions for the transmission of a UL WUS from a base station. In some instances, the one or more trigger conditions for the transmission of the UL WUS may be received via a system information block or via radio resource control signaling. In some instances, the one or more trigger conditions for the transmission of the UL WUS include a minimum logical channel (LCH) priority threshold for the associated CG-PUSCH resource as one of the one or more trigger conditions. The LCH priority threshold may be a per-UE threshold or a per-base station sleep mode threshold. In some instances, the one or more trigger conditions for the transmission of the UL WUS may include a RACH process triggered for the associated RACH resource as one of the one or more trigger conditions. In some instances, when the UE transmits a UL WUS in the last time slot before the cell DRX / DTX is turned off, the one or more trigger conditions for the transmission of the UL WUS may include a minimum LCH priority threshold for the associated CG-PUSCH resource or a RACH process triggered for the associated RACH resource as the one or more trigger conditions. In some instances, the one or more triggering conditions for transmission of the UL WUS include a minimum physical channel priority threshold of an associated dynamic grant (DG) PUSCH resource as one of the one or more triggering conditions.

[0174] At 1206, the UE may configure the UL WUS based at least in part on the indication of resources for the UL WUS and one or more triggering conditions for transmission of the UL WUS.

[0175] In some instances, the UE may detect a trigger condition for the transmission of the UL WUS and determine whether the condition for transmitting the UL WUS is met. The trigger condition may be detected at a medium access control (MAC) layer of the UE. In some instances, in order to determine whether the condition for transmitting the UL WUS is met, the UE may determine that the prohibition timer is not running at the time of the upcoming UL WUS transmission opportunity, and determine that the UL WUS transmission opportunity does not overlap with the measurement gap. In addition, the UE may then determine whether the number of transmissions is less than the configured maximum number of transmissions, and in response to determining that the number of transmissions is less than the configured maximum number of transmissions, generate an instruction for transmitting the UL WUS and reset the prohibition timer. The instruction may be generated by the MAC layer of the UE and delivered to the lower layer of the UE. In some instances, in response to determining that the condition for transmitting the UL WUS is not met, the MAC layer of the UE may notify the higher layer of the UE of the failure to transmit the UL WUS. The higher layer of the UE may include the radio resource control layer of the UE.

[0176] In some instances, the UL WUS may include one or more of: an indication of whether the UE intends to transmit a RACH transmission in an upcoming UL resource, an indication of whether the UE intends to transmit a CG-PUSCH transmission in an upcoming UL resource, an indication of which upcoming CG-PUSCH resource the UE intends to use, an indication of which upcoming RACH resource the UE intends to use, and / or an indication that the UE intends to transmit in an upcoming cell DRX / DTX off duration.

[0177] In some instances, the UE may receive multiple UL WUS configurations from a base station and select a UL WUS resource to indicate a type of transmission and / or an UL resource that the UE intends to use for an upcoming transmission. In some instances, each UL WUS configuration in the multiple UL WUS configurations is associated with a corresponding UL WUS resource. In some instances, the selection of the UL WUS resource may indicate that the UE intends to transmit a RACH transmission in an upcoming UL resource, that the UE intends to transmit a configuration grant physical uplink shared channel (CG-PUSCH) transmission in an upcoming UL resource, which upcoming CG-PUSCH resource the UE intends to use, which upcoming RACH resource the UE intends to use, and / or that the UE intends to transmit in an upcoming cell DRX / DTX off duration.

[0178] In some instances, the UE may receive an indication from the base station that the base station will wake up in one or more upcoming UL resources. In other words, the UE may send a UL WUS to the base station and receive the indication in response to the UL WUS. The UE may send pending RACH or PUSCH data to the base station in at least a portion of the one or more upcoming UL resources.

[0179] In some instances, the UE may receive an indication from the base station that the base station will not wake up in one or more upcoming UL resources. In other words, the UE may send a UL WUS to the base station and receive the indication in response to the UL WUS. The UE may suspend pending RACH or PUSCH data in the one or more upcoming UL resources.

[0180] In some examples, in response to not receiving a response to a UL WUS sent to the base station, the UE may determine that the upcoming UL resources occur in the on duration or the upcoming cell DRX / DTX. In other words, the UE may send the UL WUS and not receive a response from the base station. The UE may send pending RACH or PUSCH data to the base station in at least a portion of the upcoming UL resources.

[0181] In some instances, in response to not receiving a response to a UL WUS sent to the base station, the UE may determine that the upcoming UL resource occurs in the on duration or the upcoming cell DRX / DTX. In other words, the UE may send a UL WUS and not receive a response from the base station. The UE may suspend pending RACH or PUSCH data in the upcoming UL resource.

[0182] Fig.13 A block diagram illustrating an example of a method for determining when to send a UL WUS according to some embodiments. Among other devices, Fig.13 The method shown can be used in combination with any one of the systems, methods or devices shown in the figure. In various embodiments, some of the method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as needed. As shown in the figure, the method can operate as follows.

[0183] At 1302, a UE, such as UE 106, may detect a trigger condition for transmission of a UL WUS. The trigger condition may be detected at a medium access control (MAC) layer of the UE.

[0184] At 1304, the UE may determine whether a condition for sending a UL WUS is met. In some instances, to determine whether the condition for sending the UL WUS is met, the UE may determine that at the time of an upcoming UL WUS transmission opportunity, a prohibit timer is not running, and determine that the UL WUS transmission opportunity does not overlap with a measurement gap. In addition, the UE may then determine whether the number of transmissions is less than a configured maximum number of transmissions, and in response to determining that the number of transmissions is less than the configured maximum number of transmissions, generate an instruction for sending the UL WUS and reset the prohibit timer. The instruction may be generated by a MAC layer of the UE and delivered to a lower layer of the UE. In some instances, in response to determining that the condition for sending the UL WUS is not met, the MAC layer of the UE may notify a higher layer of the UE of a failure to send the UL WUS. The higher layer of the UE may include a radio resource control layer of the UE.

[0185] In some examples, the UE may receive an indication of resources for the UL WUS and one or more trigger conditions for transmission of the UL WUS from a base station, such as base station 102. The UE may configure the UL WUS based at least in part on the indication of resources for the UL WUS and the one or more trigger conditions for transmission of the UL WUS.

[0186] In some instances, the indication may include a prohibition timer and a maximum number of transmissions per UL WUS resource. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more logical channels. In some instances, the indication may specify that the resources for the UL WUS are not associated with any logical channel. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more upcoming configuration grant (CG) physical uplink shared channel (PUSCH) resources. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more upcoming random access channel (RACH) resources. In some instances, the indication may specify that the resources for the UL WUS are associated with an upcoming cell DRX / DTX shutdown duration. In some instances, the indication may specify that the resources for the UL WUS are configured as per UE configuration or per base station sleep mode / state configuration.

[0187] In some instances, the resource for the UL WUS may be a periodic UL resource. The indication may specify the periodicity of the periodic UL resource and the time slot offset of the periodic UL resource. The indication may specify a first configuration of the periodic UL resource for a cell discontinuous reception cycle (DRX) / discontinuous transmission cycle (DTX) on duration and a second configuration of the periodic UL resource for a cell DRX / DTX off duration. In some instances, the first configuration may specify a denser resource than the second configuration.

[0188] In some examples, the indication may specify UL resources for a number of time slots prior to the start time of the cell DRX / DTX off duration. The number of time slots may be specified via a system information block or radio resource control signaling.

[0189] In some instances, the resource for the UL WUS may be an aperiodic UL resource. The aperiodic UL resource may be triggered via signaling from the base station. The signaling may include one of UE common downlink control information (DCI), UE dedicated DCI, or medium access control (MAC) control element (CE). The UE common DCI may be DCI 2-7, for example, DCI format 2_7. The UE dedicated DCI may be DCI 1-1 and / or a paging short message. The MAC CE may activate a specific mode for UL WUS triggering.

[0192] In some instances, the UE may receive multiple UL WUS configurations from a base station and select a UL WUS resource to indicate a type of transmission and / or an UL resource that the UE intends to use for an upcoming transmission. In some instances, each UL WUS configuration in the multiple UL WUS configurations is associated with a corresponding UL WUS resource. In some instances, the selection of the UL WUS resource may indicate that the UE intends to transmit a RACH transmission in an upcoming UL resource, that the UE intends to transmit a configuration grant physical uplink shared channel (CG-PUSCH) transmission in an upcoming UL resource, which upcoming CG-PUSCH resource the UE intends to use, which upcoming RACH resource the UE intends to use, and / or that the UE intends to transmit in an upcoming cell DRX / DTX off duration.

In other words, the UE may send a UL WUS to the base station and receive the indication in response to the UL WUS. The UE may send pending RACH or PUSCH data to the base station in at least a portion of the one or more upcoming UL resources.

[0194] In some instances, the UE may receive an indication from the base station that the base station will not wake up in one or more upcoming UL resources. In other words, the UE may send a UL WUS to the base station and receive the indication in response to the UL WUS. The UE may suspend pending RACH or PUSCH data in the one or more upcoming UL resources.

[0195] In some examples, in response to not receiving a response to a UL WUS sent to the base station, the UE may determine that the upcoming UL resources occur in the on duration or the upcoming cell DRX / DTX. In other words, the UE may send the UL WUS and not receive a response from the base station.

[0207] In some instances, the UE may detect a trigger condition for the transmission of the UL WUS and determine whether the condition for transmitting the UL WUS is met. The trigger condition may be detected at a medium access control (MAC) layer of the UE. In some instances, in order to determine whether the condition for transmitting the UL WUS is met, the UE may determine that the prohibition timer is not running at the time of the upcoming UL WUS transmission opportunity, and determine that the UL WUS transmission opportunity does not overlap with the measurement gap. In addition, the UE may then determine whether the number of transmissions is less than the configured maximum number of transmissions, and in response to determining that the number of transmissions is less than the configured maximum number of transmissions, generate an instruction for transmitting the UL WUS and reset the prohibition timer.

[0245] In some instances, the UL WUS may include one or more of: an indication of whether the UE intends to transmit a RACH transmission in an upcoming UL resource, an indication of whether the UE intends to transmit a CG-PUSCH transmission in an upcoming UL resource, an indication of which upcoming CG-PUSCH resource the UE intends to use, an indication of which upcoming RACH resource the UE intends to use, and / or an indication that the UE intends to transmit in an upcoming cell DRX / DTX off duration.

[0246] In some instances, the UE may detect a trigger condition for the transmission of the UL WUS and determine whether the condition for transmitting the UL WUS is met. The trigger condition may be detected at a medium access control (MAC) layer of the UE. In some instances, in order to determine whether the condition for transmitting the UL WUS is met, the UE may determine that the prohibition timer is not running at the time of the upcoming UL WUS transmission opportunity, and determine that the UL WUS transmission opportunity does not overlap with the measurement gap. In addition, the UE may then determine whether the number of transmissions is less than the configured maximum number of transmissions, and in response to determining that the number of transmissions is less than the configured maximum number of transmissions, generate an instruction for transmitting the UL WUS and reset the prohibition timer. The instruction may be generated by the MAC layer of the UE and delivered to the lower layer of the UE. In some instances, in response to determining that the condition for transmitting the UL WUS is not met, the MAC layer of the UE may notify the higher layer of the UE of the failure to transmit the UL WUS. The higher layer of the UE may include the radio resource control layer of the UE.

[0247] In some instances, the UE may receive multiple UL WUS configurations from a base station and select a UL WUS resource to indicate a type of transmission and / or an UL resource that the UE intends to use for an upcoming transmission. In some instances, each UL WUS configuration in the multiple UL WUS configurations is associated with a corresponding UL WUS resource. In some instances, the selection of the UL WUS resource may indicate that the UE intends to transmit a RACH transmission in an upcoming UL resource, that the UE intends to transmit a configuration grant physical uplink shared channel (CG-PUSCH) transmission in an upcoming UL resource, which upcoming CG-PUSCH resource the UE intends to use, which upcoming RACH resource the UE intends to use, and / or that the UE intends to transmit in an upcoming cell DRX / DTX off duration.

[0248] Fig.18 A block diagram illustrating another example of a method for suspending the transmission of pending data after the transmission of a UL WUS according to some embodiments. Among other devices, Fig.18The method shown in can also be used together with any one of the system, method or device shown in the figure. In various embodiments, some method elements shown can be executed concurrently in a different order than shown, or can be omitted. Additional method elements can also be executed as required. As shown in the figure, the method can be operated as follows.

[0249] At 1802, a UE, such as UE 106, may determine that upcoming UL resources occur in an OFF duration of an upcoming cell DRX / DTX cycle in response to not receiving a response to a UL WUS sent to a base station, such as base station 102. In other words, the UE may send the UL WUS to the base station and not receive a response to the sending of the UL WUS from the base station.

[0250] At 1804, the UE may suspend pending RACH or PUSCH data in one or more upcoming UL resources.

[0251] In some instances, the UE may receive from a base station an indication of resources for the UL WUS and one or more trigger conditions for sending the UL WUS. The UE may configure the UL WUS based at least in part on the indication of resources for the UL WUS and the one or more trigger conditions for sending the UL WUS.

[0252] In some instances, the indication may include a prohibition timer and a maximum number of transmissions per UL WUS resource. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more logical channels. In some instances, the indication may specify that the resources for the UL WUS are not associated with any logical channel. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more upcoming configuration grant (CG) physical uplink shared channel (PUSCH) resources. In some instances, the indication may specify that the resources for the UL WUS are associated with one or more upcoming random access channel (RACH) resources. In some instances, the indication may specify that the resources for the UL WUS are associated with an upcoming cell DRX / DTX shutdown duration. In some instances, the indication may specify that the resources for the UL WUS are configured as per UE configuration or per base station sleep mode / state configuration.

[0253] In some instances, the resource for the UL WUS may be a periodic UL resource. The indication may specify the periodicity of the periodic UL resource and the time slot offset of the periodic UL resource. The indication may specify a first configuration of the periodic UL resource for a cell discontinuous reception cycle (DRX) / discontinuous transmission cycle (DTX) on duration and a second configuration of the periodic UL resource for a cell DRX / DTX off duration. In some instances, the first configuration may specify a denser resource than the second configuration.

[0254] In some examples, the indication may specify UL resources for a number of time slots prior to the start time of the cell DRX / DTX off duration. The number of time slots may be specified via a system information block or radio resource control signaling.

[0255] In some instances, the resource for the UL WUS may be an aperiodic UL resource. The aperiodic UL resource may be triggered via signaling from the base station. The signaling may include one of UE common downlink control information (DCI), UE dedicated DCI, or medium access control (MAC) control element (CE). The UE common DCI may be DCI 2-7, for example, DCI format 2_7. The UE dedicated DCI may be DCI 1-1 and / or a paging short message. The MAC CE may activate a specific mode for UL WUS triggering.

[0256] In some instances, the one or more trigger conditions for sending the UL WUS may be received via a system information block or via radio resource control signaling. In some instances, the one or more trigger conditions for sending the UL WUS include a minimum logical channel (LCH) priority threshold for the associated CG-PUSCH resource as one of the one or more trigger conditions. The LCH priority threshold may be a per-UE threshold or a per-base station sleep mode threshold. In some instances, the one or more trigger conditions for sending the UL WUS may include a RACH process triggered for the associated RACH resource as one of the one or more trigger conditions. In some instances, when the UE sends a UL WUS in the last time slot before the cell DRX / DTX off period, the one or more trigger conditions for sending the UL WUS may include a minimum LCH priority threshold for the associated CG-PUSCH resource or a RACH process triggered for the associated RACH resource as the one or more trigger conditions. In some instances, the one or more triggering conditions for transmission of the UL WUS include a minimum physical channel priority threshold of an associated dynamic grant (DG) PUSCH resource as one of the one or more triggering conditions.

[0257] In some instances, the UL WUS may include one or more of: an indication of whether the UE intends to transmit a RACH transmission in an upcoming UL resource, an indication of whether the UE intends to transmit a CG-PUSCH transmission in an upcoming UL resource, an indication of which upcoming CG-PUSCH resource the UE intends to use, an indication of which upcoming RACH resource the UE intends to use, and / or an indication that the UE intends to transmit in an upcoming cell DRX / DTX off duration.

[0258] In some instances, the UE may detect a trigger condition for the transmission of the UL WUS and determine whether the condition for transmitting the UL WUS is met. The trigger condition may be detected at a medium access control (MAC) layer of the UE. In some instances, in order to determine whether the condition for transmitting the UL WUS is met, the UE may determine that the prohibition timer is not running at the time of the upcoming UL WUS transmission opportunity, and determine that the UL WUS transmission opportunity does not overlap with the measurement gap. In addition, the UE may then determine whether the number of transmissions is less than the configured maximum number of transmissions, and in response to determining that the number of transmissions is less than the configured maximum number of transmissions, generate an instruction for transmitting the UL WUS and reset the prohibition timer. The instruction may be generated by the MAC layer of the UE and delivered to the lower layer of the UE. In some instances, in response to determining that the condition for transmitting the UL WUS is not met, the MAC layer of the UE may notify the higher layer of the UE of the failure to transmit the UL WUS. The higher layer of the UE may include the radio resource control layer of the UE.

[0259] In some instances, the UE may receive multiple UL WUS configurations from a base station and select a UL WUS resource to indicate a type of transmission and / or an UL resource that the UE intends to use for an upcoming transmission. In some instances, each UL WUS configuration in the multiple UL WUS configurations is associated with a corresponding UL WUS resource. In some instances, the selection of the UL WUS resource may indicate that the UE intends to transmit a RACH transmission in an upcoming UL resource, that the UE intends to transmit a configuration grant physical uplink shared channel (CG-PUSCH) transmission in an upcoming UL resource, which upcoming CG-PUSCH resource the UE intends to use, which upcoming RACH resource the UE intends to use, and / or that the UE intends to transmit in an upcoming cell DRX / DTX off duration.
