Discontinuous reception for energy-saving base stations

Abstract

Aspects are provided that allow a network entity to receive uplink transmissions from a UE in a UE DTX or cell DRX based on dynamic activation or deactivation of a DTX configuration or an associated uplink transmission configuration relative to the DTX. In some examples, the UE receives a DTX configuration associated with a UE transmission configuration and indicating an active time duration for UE transmissions associated with the UE transmission configuration. The UE also receives the uplink transmission configuration, such as an SR configuration, and a semi-static or dynamic indication of the DTX configuration or an active state of the uplink transmission configuration relative to the DTX configuration. Thereafter, the UE transmits the UE transmission during the active time duration indicated in the DTX configuration based on the active state. Thus, less uplink transmission monitoring may be caused at the base station, thereby providing network energy savings.

Technical Field

[0003] The present disclosure relates generally to wireless communications, and more particularly, to a wireless communication system providing cell discontinuous reception (DRX). Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcast. Typical wireless communication systems may employ multiple access technologies capable of supporting communication with multiple users by sharing available system resources. Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and time division synchronous code division multiple access (TD-SCDMA) systems.

[0005] These multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different wireless devices to communicate at city, country, region, and even global levels. An example telecommunication standard is 5G New Radio (NR). 5G NR is part of the continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP) to meet new requirements associated with latency, reliability, security, scalability (e.g., with the Internet of Things (IoT)) and other requirements. 5GNR includes services associated with enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable low latency communication (URLLC). Certain aspects of 5G NR may be based on 4G Long Term Evolution (LTE) standards. It is necessary to further improve 5G NR technology. In addition, these improvements may also be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0027] The specific embodiments described below in conjunction with the accompanying drawings are intended as descriptions of various configurations and are not intended to represent the only configurations with which the concepts described herein can be practiced. In order to provide a thorough understanding of the various concepts, the specific embodiments include specific details. However, it is apparent to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid blurring such concepts.

[0028] Aspects generally relate to cell discontinuous reception (DRX). More specifically, aspects specifically relate to a wireless communication system, wherein a network entity such as a base station provides a discontinuous transmission (DTX) configuration associated with an uplink transmission configuration to a user equipment (UE) to provide network energy saving. These aspects reduce energy consumption at a base station by allowing the base station to avoid actively and blindly monitoring associated, unscheduled or unused uplink transmissions (such as scheduling request (SR) or configuration grant (CG) physical uplink shared channel (CG-PUSCH) transmissions) during the off duration in a DTX cycle. Some examples of these aspects generally relate to semi-static or dynamic activation or deactivation of a DTX configuration. These examples achieve maximum energy savings at a base station by allowing the base station to suppress monitoring of general uplink transmissions during the off duration of a DTX cycle when the DTX configuration is active. Other examples of these aspects specifically relate to semi-static or dynamic activation or deactivation of an uplink transmission configuration relative to a DTX configuration. These examples provide the base station with flexibility to configure certain uplink transmission configurations (such as CG-PUSCH or SR configurations associated with high priority logical channels or delay sensitive services) to be deactivated or excluded from DTX so that delay sensitive data may not be delayed due to the DTX off duration, while other uplink transmission configurations (such as SR configurations associated with low priority logical channels for delay tolerant services) may be activated or subject to DTX to allow the base station to still obtain network energy savings. Additional examples relate to dynamic activation or deactivation of uplink transmission configurations that are independent of the DTX configuration. In any of these aspects and examples previously described and to be described, the DTX configuration may refer to a UE DTX configuration or a cell DRX configuration.

[0029] In some examples, the base station may dynamically activate or deactivate the SR configuration, and thus activate or deactivate the SR transmission via layer 1 (L1) or layer 2 (L2) signaling, regardless of the DTX configuration. For example, after the base station configures the SR configuration for the UE via radio resource control (RRC) configuration, the base station may send a message to the UE via L1 or L2 signaling to activate or deactivate the SR configuration. In another example, after the base station configures the SR resource configuration for the UE via RRC configuration, the base station may send a message to the UE via L1 or L2 signaling to activate or deactivate the SR resource configuration. In other examples, the base station may configure parameters associated with the SR configuration or SR resource configuration in a message or L1 / L2 signaling for activating or deactivating SR transmission. In another example, the base station may configure a message for modifying logical channel parameters associated with the SR configuration. Activation and deactivation may be specific to one configuration or transmission, or activation and deactivation may be applicable to multiple SR configurations or transmissions. Similarly, activation and deactivation may be specific to one UE, or activation and deactivation may be signaled by multicast or broadcast to a cell including multiple UEs. In other examples, the base station may configure multiple PUCCH resources for SR on a given bandwidth part (BWP) so that even if the base station deactivates one PUCCH resource for SR, SR may have at least one other PUCCH resource available for UE application. In other examples, the base station may not activate or deactivate the SR opportunity, but instead use L1 / L2 signaling to reconfigure the SR opportunity. In any of the foregoing examples, the base station may indicate via L1 / L2 signaling the time at which activation, deactivation, or reconfiguration of the SR configuration, SR resource configuration, logical channel configuration, or other SR-associated configuration takes effect. In any of the foregoing examples, the base station may dynamically activate, deactivate, or reconfigure the SR configuration or SR-associated configuration based on one or more UE capabilities. The base station may similarly apply any of the foregoing concepts to CG configurations for configuring grant type 1 and configuring grant type 2.

[0030] Additionally, in other examples, the base station may provide a semi-static DTX configuration to the UE. In response to receiving the DTX configuration, the UE may transmit in valid resources falling within the active interval indicated in the DTX configuration, and suspend transmission outside these intervals while the DTX configuration is active. The base station may semi-statically activate or deactivate the DTX configuration via RRC signaling or dynamically via L1 or L2 signaling. Thus, when the DTX configuration is active, the UE may send general uplink transmissions during the on duration of the DTX cycle instead of during the off duration, and when the DTX configuration is inactive, the UE may ignore the DTX cycle and send uplink transmissions during the off duration. In addition, the base station may apply any of the aforementioned example concepts of activation, deactivation, and reconfiguration described with respect to the SR configuration and CG-PUSCH configuration in conjunction with the DTX application. For example, the base station may dynamically via L1 or L2 signaling or semi-statically via RRC signaling select to activate, deactivate, or reconfigure the SR configuration, SR resource configuration, CG configuration, or other uplink transmission configuration relative to the DTX configuration. Therefore, when a specific configuration is active, during the on duration of the DTX cycle instead of the off duration, the UE may send a general SR transmission, an SR transmission associated with a specific SR configuration, a general CG-PUSCH transmission, a CG-PUSCH transmission associated with a specific CG-PUSCH configuration, a random access channel (RACH) transmission, etc. according to the specific configuration. On the other hand, when the specific configuration is inactive, the UE may ignore the DTX cycle and send SR, CG-PUSCH, RACH, or other transmissions associated with the specific configuration during the off duration. In addition, in other examples, the base station may apply L1 or L2 signaling to interrupt or cancel the first active time indicated by the DTX configuration, the base station may reconfigure the parameters of the DTX configuration via L1 or L2 signaling, the base station may define one or more UE capabilities for supporting one or more DTX configurations, or the base station may indicate at least one parameter of the DTX configuration via a system information block (SIB) or multicast signaling.

[0031] Several aspects of telecommunication systems will now be presented with reference to various apparatus and methods. These apparatus and methods will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, components, circuits, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using electronic hardware, computer software, or any combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0032] As an example, an element, or any part of an element, or any combination of elements can be implemented as a "processing system", which includes one or more processors. Examples of processors include microprocessors, microcontrollers, graphics processing units (GPUs), central processing units (CPUs), application processors, digital signal processors (DSPs), reduced instruction set computing (RISC) processors, systems on chip (SoCs), baseband processors, field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic components, discrete hardware circuits, and other suitable hardware configured to perform various functionalities described throughout the present disclosure. One or more processors in a processing system can execute software. Whether it is referred to as software, firmware, middleware, microcode, hardware description language, or other names, software should be widely interpreted as meaning instructions, instruction sets, codes, code segments, program codes, programs, subroutines, software components, applications, software applications, software packages, routines, subroutines, objects, executable files, threads of execution, processes, functions, etc.

[0033] Therefore, in one or more example embodiments, the described functions can be implemented with hardware, software or any combination thereof. If implemented in software, the function can be stored or encoded on a computer-readable medium as one or more instructions or codes. Computer-readable media include computer storage media. Storage media can be any available medium that can be accessed by a computer. By way of example and not limitation, such computer-readable media can include a random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), an optical disk storage device, a magnetic disk storage device, other magnetic storage devices, a combination of computer-readable media of the above type, or any other medium that can be used to store computer executable code in the form of instructions or data structures that can be accessed by a computer.

[0034] Figure 1A 1 is a diagram illustrating an example of a wireless communication system and access network 100. The wireless communication system (also referred to as a wireless wide area network (WWAN)) includes a base station 102, a user equipment (UE) 104, an evolved packet core (EPC) 160, and another core network 190 (e.g., a 5G core (5GC)). The base station 102 may include a macro cell (a high-power cellular base station) and / or a small cell (a low-power cellular base station). A macro cell includes a base station. A small cell includes a femto cell, a pico cell, and a micro cell.

[0035] The base station 102 configured for 4G Long Term Evolution (LTE) (collectively referred to as Evolved Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-UTRAN)) can interface with the EPC 160 via a first backhaul link 132 (e.g., S1 interface). The base station 102 configured for 5G New Radio (NR) (collectively referred to as Next Generation RAN (NG-RAN)) can interface with the core network 190 via a second backhaul link 184. Among other functions, the base station 102 can also perform one or more of the following functions: delivery of user data, radio channel encryption and decryption, integrity protection, header compression, mobility control functions (e.g., handover, dual connectivity), inter-cell interference coordination, connection establishment and release, load balancing, distribution of non-access stratum (NAS) messages, NAS node selection, synchronization, radio access network (RAN) sharing, multimedia broadcast multicast service (MBMS), subscriber and equipment tracking, RAN information management (RIM), paging, positioning, and delivery of warning messages. The base stations 102 may communicate with each other directly or indirectly (eg, via the EPC 160 or the core network 190) via the third backhaul link 134 (eg, an X2 interface). The first backhaul link 132, the second backhaul link 184, and the third backhaul link 134 may be wired or wireless.

[0036] Base station 102 can communicate wirelessly with UE 104. Each of base stations 102 can provide communication coverage for a corresponding geographic coverage area 110. There may be overlapping geographic coverage areas 110. For example, a small cell 102' can have a coverage area 110' that overlaps with the coverage area 110 of one or more macro base stations 102. A network including both small cells and macro cells can be referred to as a heterogeneous network. A heterogeneous network can also include a home evolved Node B (eNB) (HeNB), which can provide services to a restricted group called a closed subscriber group (CSG). A communication link 120 between base station 102 and UE 104 can include an uplink (UL) (also called a reverse link) transmission from UE 104 to base station 102 and / or a downlink (DL) (also called a forward link) transmission from base station 102 to UE 104. The communication link 120 can use multiple input multiple output (MIMO) antenna technology, including spatial multiplexing, beamforming and / or transmit diversity. The communication link can be through one or more carriers. For each carrier allocated in the carrier aggregation for up to a total of up to Yx MHz (x component carriers) for transmission in each direction, the base station 102 / UE 104 can use a spectrum of up to Y megahertz (MHz) (e.g., 5 MHz, 10 MHz, 15 MHz, 20 MHz, 100 MHz, 400 MHz, etc.) bandwidth. The carriers may or may not be adjacent to each other. The allocation of carriers may be asymmetric with respect to DL and UL (e.g., more or fewer carriers may be allocated for DL ​​compared to UL). The component carrier may include a primary component carrier and one or more secondary component carriers. The primary component carrier may be referred to as a primary cell (PCell) and the secondary component carrier may be referred to as a secondary cell (SCell).

[0037] Some UEs 104 may communicate with each other using a device-to-device (D2D) communication link 158. The D2D communication link 158 may use DL / UL WWAN spectrum. The D2D communication link 158 may use one or more sidelink channels, such as a physical sidelink broadcast channel (PSBCH), a physical sidelink discovery channel (PSDCH), a physical sidelink shared channel (PSSCH), and a physical sidelink control channel (PSCCH). The D2D communication may be through a variety of wireless D2D communication systems, such as, for example, WiMedia, Bluetooth, ZigBee, Wi-Fi based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard, LTE, or NR.

[0038] The wireless communication system may also include a Wi-Fi access point (AP) 150 that communicates with a Wi-Fi station (STA) 152 via a communication link 154 in, for example, a 5 gigahertz (GHz) unlicensed spectrum. When communicating in the unlicensed spectrum, the STA 152 / AP 150 may perform a clear channel assessment (CCA) to determine whether a channel is available prior to communication.

[0039] The small cell 102' may operate in licensed and / or unlicensed spectrum. When operating in an unlicensed spectrum, the small cell 102' may employ NR and use the same unlicensed spectrum (e.g., 5 GHz, etc.) as used by the Wi-Fi AP 150. The small cell 102' employing NR in the unlicensed spectrum may improve the coverage of the access network and / or increase the capacity of the access network.

[0040] The electromagnetic spectrum is typically subdivided into various categories, bands, channels, etc. based on frequency / wavelength. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Frequencies between FR1 and FR2 are typically referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is typically (interchangeably) referred to as the “sub-6 GHz” band in various documents and articles. A similar naming issue sometimes occurs with respect to FR2, which is typically (interchangeably) referred to as the “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz–300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0041] In view of the above aspects, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, it can broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, it can broadly represent frequencies that may include mid-band frequencies, may be within FR2, or may be within the EHF band.

[0042] The base station 102, whether a small cell 102' or a large cell (e.g., a macro base station), may include and / or be referred to as an eNB, a gNodeB (gNB), or another type of base station. Some base stations, such as gNB 180, may operate in the traditional sub-6 GHz spectrum, in millimeter wave frequencies, and / or near millimeter wave frequencies to communicate with the UE 104. When the gNB 180 operates in millimeter wave or near millimeter wave frequencies, the gNB 180 may be referred to as a millimeter wave base station. The millimeter wave base station 180 may utilize beamforming 182 with the UE 104 to compensate for path loss and short range. The base station 180 and the UE 104 may each include multiple antennas, such as antenna elements, antenna panels, and / or antenna arrays, to facilitate beamforming.

[0043] Base station 180 may send beamformed signals to UE 104 in one or more transmit directions 182'. UE 104 may receive beamformed signals from base station 180 in one or more receive directions 182". UE 104 may also send beamformed signals to base station 180 in one or more transmit directions. Base station 180 may receive beamformed signals from UE 104 in one or more receive directions. Base station 180 / UE 104 may perform beam training to determine the best receive direction and transmit direction for each of base station 180 / UE 104. The transmit direction and receive direction of base station 180 may be the same or different. The transmit direction and receive direction of UE 104 may be the same or different.

[0044] The EPC 160 may include a mobility management entity (MME) 162, other MMEs 164, a serving gateway 166, an MBMS gateway 168, a broadcast multicast service center (BM-SC) 170, and a packet data network (PDN) gateway 172. The MME 162 may communicate with a home subscriber server (HSS) 174. The MME 162 is a control node that handles signaling between the UE 104 and the EPC 160. Typically, the MME 162 provides bearer and connection management. All user Internet Protocol (IP) packets are delivered through the serving gateway 166, which itself is connected to the PDN gateway 172. The PDN gateway 172 provides UE IP address allocation and other functions. The PDN gateway 172 and the BM-SC 170 are connected to IP services 176. The IP services 176 may include the Internet, an intranet, an IP multimedia subsystem (IMS), a PS streaming service, and / or other IP services. The BM-SC 170 may provide functions for MBMS user service configuration and delivery. BM-SC 170 may serve as an entry point for content provider MBMS delivery, may be used to authorize and initiate MBMS bearer services in a public land mobile network (PLMN), and may be used to schedule MBMS delivery. MBMS gateway 168 may be used to distribute MBMS services to base stations 102 belonging to a multicast broadcast single frequency network (MBSFN) area of ​​a broadcast specific service, and may be responsible for session management (start / stop) and for collecting eMBMS related billing information.

[0045] The core network 190 may include an access and mobility management function (AMF) 192, other AMFs 193, a session management function (SMF) 194, and a user plane function (UPF) 195. The AMF 192 may communicate with a unified data management (UDM) 196. The AMF 192 is a control node that handles signaling between the UE 104 and the core network 190. Typically, the AMF 192 provides quality of service (QoS) flows and session management. All user IP packets are delivered through the UPF 195. The UPF 195 provides UE IP address allocation and other functions. The UPF 195 is connected to an IP service 197. The IP service 197 may include the Internet, an intranet, an IMS, a packet switching (PS) streaming media service, and / or other IP services.

[0046] Base stations may include and / or be referred to as gNBs, Node Bs, eNBs, access points, base transceivers, radio base stations, radio transceivers, transceiver functions, basic service sets (BSSs), extended service sets (ESSs), transmit receive points (TRPs), or some other suitable terminology. Base stations 102 provide access points to EPC 160 or core network 190 for UEs 104. Examples of UEs 104 include cellular phones, smart phones, session initiation protocol (SIP) phones, laptops, personal digital assistants (PDAs), satellite radios, global positioning systems, multimedia devices, video devices, digital audio players (e.g., MP3 players), cameras, game consoles, tablets, smart devices, wearable devices, vehicles, electric meters, gas pumps, large or small kitchen appliances, healthcare devices, implants, sensors / actuators, displays, or any other similarly functional devices. Some of the UEs 104 may be referred to as IoT devices (e.g., parking meters, gas pumps, toasters, vehicles, heart monitors, etc.). UE 104 may also be referred to as a station, a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communication device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.

[0047] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a network device, a mobility element of a network, a RAN node, a core network node, a network element or network equipment such as a BS or one or more units (or one or more components) performing base station functionality can be implemented in an aggregated or decomposed architecture. For example, a BS (such as a Node B (NB), an eNB, an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) can be implemented as an aggregated base station (also called an independent BS or a monolithic BS) or a decomposed base station.

[0048] The aggregated base station may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node. The decomposed base station 181 may be configured to utilize a protocol stack physically or logically distributed between two or more units, such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs). In some aspects, the CU 183 may be implemented within a RAN node, and one or more DUs 185 may be co-located with the CU, or alternatively, may be geographically or virtually distributed in one or more other RAN nodes. The DU may be implemented to communicate with one or more RUs 187. Each of the CU, DU, and RU may also be implemented as a virtual unit, i.e., a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0049] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a disaggregated base station may be used in an integrated access and backhaul (IAB) network, an open radio access network (O-RAN (network configurations such as those initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)). Decomposition may include distributing functionality across two or more units at various physical locations, as well as virtually distributing functionality of at least one unit, which may enable flexibility in network design. Individual units of a disaggregated base station or disaggregated RAN architecture may be configured for wired or wireless communication with at least one other unit.

[0050] Figure 1B A diagram illustrating an example decomposed base station 181 architecture is shown. The decomposed base station 181 architecture may include one or more CUs 183, which may communicate directly with the core network 190 via a backhaul link, or indirectly with the core network 190 through one or more decomposed base station units (such as a near real-time RIC 125 via an E2 link, or a non-real-time RIC 115 associated with a service management and orchestration (SMO) framework 105, or both). The CU 183 may communicate with one or more DUs 185 via corresponding midhaul links, such as an F1 interface. The DU 185 may communicate with one or more RUs 187 via corresponding fronthaul links. The RUs 187 may communicate with the UEs 104, respectively, via one or more radio frequency (RF) access links. In some implementations, the UE 104 may be served simultaneously by multiple RUs 187.

[0051] Each of the units (i.e., CU 183, DU 185, RU 187, and near-RT RIC 125, non-RT RIC 115, and SMO framework 105) may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to the communication interfaces of these units may be configured to communicate with one or more of the other units via a transmission medium. For example, a unit may include a wired interface configured to receive or send signals to one or more of the other units via a wired transmission medium. Additionally, these units may include a wireless interface that may include a receiver, a transmitter, or a transceiver (such as a radio frequency (RF) transceiver) configured to receive or send signals, or both, to one or more of the other units on a wireless transmission medium.

[0052] In some aspects, CU 183 may host higher-layer control functions. Such control functions may include radio resource control (RRC), packet data convergence protocol (PDCP), service data adaptation protocol (SDAP), etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 183. CU 183 may be configured to handle user plane functionality (i.e., central unit-user plane (CU-UP)), control plane functionality (i.e., central unit-control plane (CU-CP)), or a combination thereof. In some specific implementations, CU 183 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 183 may be implemented to communicate with DU 185 for network control and signaling.

[0053] DU 185 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RU 187. In some aspects, DU 185 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc.) based at least in part on functional splits such as those defined by the 3rd Generation Partnership Project (3GPP). In some aspects, DU 185 may also host one or more low PHY layers. Each layer (or module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by DU 185 or with control functions hosted by CU 183.

[0054] The lower layer functionality may be implemented by one or more RUs 187. In some deployments, the RU 187 controlled by the DU 185 may correspond to a logical node that hosts RF processing functions or low PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on functional splitting (such as lower layer functional splitting). In such an architecture, the RU 187 may be implemented to handle over-the-air (OTA) communications with one or more UEs 104. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 187 may be controlled by the corresponding DU 185. In some scenarios, this configuration may enable the DU 185 and CU 183 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0055] The SMO framework 105 may be configured to support RAN deployment and configuration of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 105 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 105 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) 189) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 183, DU 185, RU 187, and near-RT RIC 125. In some specific implementations, the SMO framework 105 may communicate with hardware aspects of the 4G RAN such as an open eNB (O-eNB) 111 via the O1 interface. Additionally, in some specific implementations, the SMO framework 105 may communicate directly with one or more RUs 187 via the O1 interface. The SMO framework 105 may also include a non-RT RIC 115 configured to support the functionality of the SMO framework 105 .

[0056] The non-RT RIC 115 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 125. The non-RT RIC 115 may be coupled to or in communication with the near-RT RIC 125 (such as via an A1 interface). The near-RT RIC 125 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 183, one or more DUs 185, or both, and the O-eNB with the near-RT RIC 125.

[0057] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 125, the non-RT RIC 115 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 125 and may be received from a non-network data source or from a network function at the SMO framework 105 or the non-RT RIC 115. In some examples, the non-RT RIC 115 or the near-RT RIC 125 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 115 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 105 (such as via reconfiguration of O1) or via the creation of RAN management policies (such as A1 policies).

[0058] See again Figure 1AIn certain aspects, the UE 104 may include a UE DTX component 198a configured to receive a DTX configuration associated with the UE transmission and indicating an active time duration for the UE transmission; and to transmit the UE transmission during the active time duration indicated in the DTX configuration. Similarly, the base station 102 / 180 may include a NW DRX component 199a configured to transmit a DTX configuration associated with the UE transmission and indicating an active time duration for the UE transmission; and to receive the UE transmission during the active time duration indicated in the DTX configuration. The DTX configuration referenced in either component may be a UE DTX configuration or a cell DRX configuration. Thus, the UE transmission may be, for example, an SR, CG-PUSCH transmission, or other uplink transmission that the UE 104 or UE DTX component 198a may transmit and the base station 102 / 180 or NW DRX component 199a may receive during the active time duration or on duration of the UE DTX cycle or cell DRX cycle configured in the DTX configuration. In some examples, the DTX configuration may be semi-statically or dynamically activated or deactivated relative to UE transmission. For example, the DTX configuration or other RRC message may semi-statically indicate the DTX activity state, or the DCI or medium access control (MAC) control element (MAC-CE) may dynamically indicate the DTX activity state, which indicates whether the DTX configuration is active or inactive. If the DTX activity state is active, the UE may send and the base station may receive uplink transmissions during the on duration of the UE DTX cycle or the cell DRX cycle, but not during the off duration. If the DTX activity state is inactive, the UE and the base station may ignore the UE DTX cycle or the cell DRX cycle, and thus the UE may send and the base station may receive even during the off duration.

[0059] In some examples, a configuration that a UE transmits or is associated with a UE transmit may be activated or deactivated relative to a DTX configuration. For example, the UE 104 may also include an active SR transmitting component 198b, which is configured to receive an SR configuration; receive a message indicating an activity state of the SR configuration, wherein the activity state indicates whether the SR configuration is active or inactive; and send an SR associated with the SR configuration based on the message. Similarly, the base station 102 / 180 may also include an active SR receiving component 199b, which is configured to send an SR configuration; send a message indicating an activity state of the SR configuration, wherein the activity state indicates whether the SR configuration is active or inactive; and receive an SR associated with the SR configuration based on the message. If the message indicates that the SR configuration is active relative to the DTX configuration, the UE 104 may send and the base station 102 / 180 may receive the SR during the on duration of the UE DTX cycle or the cell DRX cycle configured in the DTX configuration but not during the off duration. If the SR configuration is inactive relative to the DTX configuration, the UE 104 and the base station 102 / 180 may ignore the UE DTX cycle or the cell DRX cycle, and thus the UE may send and the base station may receive the SR even in the OFF duration.

[0060] The aforementioned concepts may be similarly applicable to other configurations associated with UE transmissions, such as configuration grant configurations for CG-PUSCH transmissions. In addition, these concepts may be similarly applicable to SR, CG-PUSCH transmissions, or other uplink transmissions independently of the DTX configuration. For example, if the message indicates that the SR configuration is active regardless of the DTX configuration, the UE 104 may send and the base station 102 / 180 may receive the SR during the on duration or off duration of the UE DTX cycle or cell DRX cycle configured in the DTX configuration, and if the message indicates that the SR configuration is inactive regardless of the DTX configuration, the UE may not send the SR and the base station may not receive the SR even during the on duration.

[0061] Although the present disclosure may focus on 5G NR, the concepts and aspects described herein may be applicable to other similar areas such as LTE, Advanced LTE (LTE-A), Code Division Multiple Access (CDMA), Global System for Mobile Communications (GSM), and / or other wireless / radio access technologies.

[0062] Figure 2A FIG200 is a diagram illustrating an example of a first subframe within a 5G NR frame structure. Figure 2B FIG230 is a diagram illustrating an example of DL channels within a 5G NR subframe. Figure 2C FIG250 is a diagram illustrating an example of a second subframe within a 5G NR frame structure. Figure 2DFIG280 is a diagram illustrating an example of an UL channel within a 5G NR subframe. The 5G NR frame structure may be frequency division duplex (FDD) (wherein for a particular set of subcarriers (carrier system bandwidth), a subframe within the subcarrier set is dedicated to either DL or UL), or may be time division duplex (TDD) (wherein for a particular set of subcarriers (carrier system bandwidth), a subframe within the subcarrier set is dedicated to both DL and UL). Figure 2A , Figure 2C In the example provided, the 5G NR frame structure is assumed to be TDD, where subframe 4 is configured with slot format 28 (most of which are DL), where D is DL, U is UL, and F is flexible between DL / UL, and subframe 3 is configured with slot format 34 (most of which are UL). Although subframes 3 and 4 are shown as having slot formats 34 and 28, respectively, any particular subframe may be configured with any of the various available slot formats 0-61. Slot formats 0 and 1 are full DL and full UL, respectively. Other slot formats 2-61 include a mix of DL, UL and flexible symbols. The UE is configured with the slot format through the received slot format indicator (SFI) (dynamically configured through DL control information (DCI) or semi-statically / statically configured through radio resource control (RRC) signaling). Note that the following description also applies to the 5G NR frame structure as TDD.

[0063] Other wireless communication technologies may have different frame structures and / or different channels. For example, a 10 millisecond (ms) frame may be divided into 10 equally sized subframes (1 ms). Each subframe may include one or more time slots. A subframe may also include a microslot, which may include 7, 4, or 2 symbols. Each time slot may include 7 or 14 symbols, depending on the time slot configuration. For time slot configuration 0, each time slot may include 14 symbols, and for time slot configuration 1, each time slot may include 7 symbols. The symbol on the DL may be a cyclic prefix (CP) orthogonal frequency division multiplexing (OFDM) (CP-OFDM) symbol. The symbol on the UL may be a CP-OFDM symbol (for high throughput scenarios) or a discrete Fourier transform (DFT) spread OFDM (DFT-s-OFDM) symbol (also known as a single carrier frequency division multiple access (SC-FDMA) symbol) (for power-constrained scenarios; limited to single-stream transmission). The number of time slots in a subframe is based on the time slot configuration and parameter set (numerology). For slot configuration 0, different parameter sets μ0 to 4 allow 1, 2, 4, 8, and 16 slots per subframe, respectively. For slot configuration 1, different parameter sets 0 to 2 allow 2, 4, and 8 slots per subframe, respectively. Accordingly, for slot configuration 0 and parameter set μ, there are 14 symbols per slot and 2 per subframe. μtime slots. The subcarrier spacing and symbol length / duration are functions of the parameter set. The subcarrier spacing can be equal to 2 μ *15 kilohertz (kHz), where μ is parameter set 0 to 4. Therefore, the subcarrier spacing for parameter set μ=0 is 15 kHz, and the subcarrier spacing for parameter set μ=4 is 240 kHz. The symbol length / duration is inversely related to the subcarrier spacing. FIG. 2A to FIG. 2D An example is provided for slot configuration 0 with 14 symbols per slot and parameter set μ=2 with 4 slots per subframe. The slot duration is 0.25 ms, the subcarrier spacing is 60 kHz, and the symbol duration is approximately 16.67 μs. Within a frame set, there may be one or more different bandwidth parts (BWPs) that are frequency-division multiplexed (see Figure 2B ). Each BWP can have a specific set of parameters.

[0064] A resource grid may be used to represent the frame structure. Each slot includes a resource block (RB) (also called a physical RB (PRB)) extending over 12 consecutive subcarriers. The resource grid is divided into a number of resource elements (REs). The number of bits carried by each RE depends on the modulation scheme.

[0065] like Figure 2A As illustrated, some of the REs carry reference (pilot) signals (RS) for the UE. The RS may include a demodulation RS (DM-RS) for channel estimation at the UE (indicated as R for one particular configuration). x , where 100x is the port number, but other DM-RS configurations are possible) and a channel state information reference signal (CSI-RS). RS may also include beam measurement RS (BRS), beam refinement RS (BRRS) and phase tracking RS (PT-RS).

[0066] Figure 2BExamples of various DL channels within a subframe of a frame are illustrated. The physical downlink control channel (PDCCH) carries DCI within one or more control channel elements (CCEs), each CCE including nine RE groups (REGs), each REG including four consecutive REs in an OFDM symbol. The PDCCH within a BWP may be referred to as a control resource set (CORESET). Additional BWPs may be located at higher and / or lower frequencies on the channel bandwidth. The primary synchronization signal (PSS) may be within symbol 2 of a specific subframe of a frame. The PSS is used by UE 104 to determine subframe / symbol timing and physical layer identification. The secondary synchronization signal (SSS) may be within symbol 4 of a specific subframe of a frame. The SSS is used by the UE to determine the physical layer cell identification group number and radio frame timing. Based on the physical layer identification and the physical layer cell identification group number, the UE may determine the physical cell identifier (PCI). Based on the PCI, the UE may determine the position of the aforementioned DM-RS. The physical broadcast channel (PBCH) carrying the master information block (MIB) can be logically grouped with the PSS and SSS to form a synchronization signal (SS) / PBCH block (also referred to as an SS block (SSB)). The MIB provides the number of RBs in the system bandwidth and the system frame number (SFN). The physical downlink shared channel (PDSCH) carries user data, broadcast system information not sent over the PBCH (such as the system information block (SIB)), and paging messages.

[0067] like Figure 2C As illustrated, some of the REs carry DM-RS (indicated as R for a particular configuration, but other DM-RS configurations are possible) for channel estimation at the base station. The UE may send a DM-RS for a physical uplink control channel (PUCCH) and a DM-RS for a physical uplink shared channel (PUSCH). The PUSCH DM-RS may be sent in the first or first two symbols of the PUSCH. Depending on whether a short PUCCH or a long PUCCH is sent and depending on the specific PUCCH format used, the PUCCH DM-RS may be sent in different configurations. The UE may send a sounding reference signal (SRS). The SRS may be sent in the last symbol of a subframe. The SRS may have a comb structure, and the UE may send the SRS on one of the comb teeth. The SRS may be used by the base station for channel quality estimation to achieve frequency-dependent scheduling of the UL.

[0068] Figure 2DExamples of various UL channels within a subframe of a frame are illustrated. The PUCCH may be located at a position as indicated in one configuration. The PUCCH carries uplink control information (UCI), such as scheduling requests, channel quality indicators (CQI), precoding matrix indicators (PMI), rank indicators (RI), and hybrid automatic repeat request (HARQ) acknowledgement (ACK) / negative acknowledgement (NACK) feedback. The PUSCH carries data and may additionally be used to carry buffer status reports (BSRs), power headroom reports (PHRs), and / or UCI.

[0069] Figure 3 3 is a block diagram of a base station 310 in an access network communicating with a UE 350. In the DL, IP packets from the EPC 160 may be provided to the controller / processor 375. The controller / processor 375 implements layer 3 and layer 2 functionality. Layer 3 includes a radio resource control (RRC) layer, and layer 2 includes a service data adaptation protocol (SDAP) layer, a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer, and a medium access control (MAC) layer. The controller / processor 375 provides RRC layer functionality associated with broadcasting of system information (e.g., MIB, SIB), RRC connection control (e.g., RRC connection paging, RRC connection establishment, RRC connection modification, and RRC connection release), inter-radio access technology (RAT) mobility, and measurement configuration for UE measurement reporting; PDCP layer functionality associated with header compression / decompression, security (encryption, decryption, integrity protection, integrity verification), and handover support functions; RLC layer functionality associated with delivery of upper layer packet data units (PDUs), error correction through ARQ, concatenation, segmentation and reassembly of RLC service data units (SDUs), re-segmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto transport blocks (TBs), demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0070] The transmit (TX) processor 316 and receive (RX) processor 370 implement layer 1 functionality associated with various signal processing functions. Layer 1 (which includes the physical (PHY) layer) may include error detection on the transport channel, forward error correction (FEC) coding / decoding of the transport channel, interleaving, rate matching, mapping onto the physical channel, modulation / demodulation of the physical channel, and MIMO antenna processing. The TX processor 316 handles the mapping to the signal constellation based on various modulation schemes (e.g., binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), M-order phase shift keying (M-PSK), M-order quadrature amplitude modulation (M-QAM)). The coded and modulated symbols may then be separated into parallel streams. Each stream may then be mapped to an OFDM subcarrier, multiplexed with a reference signal (e.g., pilot) in the time and / or frequency domain, and then combined together using an inverse fast Fourier transform (IFFT) to produce a physical channel carrying a time domain OFDM symbol stream. The OFDM stream is spatially pre-coded to generate multiple spatial streams. Channel estimates from channel estimator 374 may be used to determine coding and modulation schemes, as well as for spatial processing. Channel estimates may be derived based on reference signals and / or channel condition feedback sent by UE 350. Each spatial stream may then be provided to a different antenna 320 via a separate transmitter 318TX. Each transmitter 318TX may modulate an RF carrier with a corresponding spatial stream for transmission.

[0071] At the UE 350, each receiver 354RX receives a signal through its corresponding antenna 352. Each receiver 354RX recovers the information modulated onto the RF carrier and provides the information to a receive (RX) processor 356. The TX processor 368 and the RX processor 356 implement layer 1 functionality associated with various signal processing functions. The RX processor 356 can perform spatial processing on the information to recover any spatial stream destined for the UE 350. If multiple spatial streams are destined for the UE 350, they can be combined into a single OFDM symbol stream by the RX processor 356. The RX processor 356 then converts the OFDM symbol stream from the time domain to the frequency domain using a fast Fourier transform (FFT). The frequency domain signal includes a separate OFDM symbol stream for each subcarrier of the OFDM signal. The symbols on each subcarrier and the reference signal are recovered and demodulated by determining the signal constellation point most likely to be sent by the base station 310. These soft decisions can be based on channel estimates calculated by the channel estimator 358. The soft decisions are then decoded and deinterleaved to recover the data and control signals originally sent on the physical channel by the base station 310. The data and control signals are then provided to the controller / processor 359, which implements layer 3 and layer 2 functionality.

[0072] The controller / processor 359 may be associated with a memory 360 that stores program codes and data. The memory 360 may be referred to as a computer readable medium. In the UL, the controller / processor 359 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, and control signal processing to recover IP packets from the EPC 160. The controller / processor 359 is also responsible for error detection using an ACK and / or NACK protocol to support HARQ operations.

[0073] Similar to the functionality described in conjunction with DL transmissions performed by the base station 310, the controller / processor 359 provides RRC layer functionality associated with system information (e.g., MIB, SIB) acquisition, RRC connection, and measurement reporting; PDCP layer functionality associated with header compression / decompression and security (encryption, decryption, integrity protection, integrity verification); RLC layer functionality associated with delivery of upper layer PDUs, error correction through ARQ, concatenation, segmentation and reassembly of RLC SDUs, resegmentation of RLC data PDUs, and reordering of RLC data PDUs; and MAC layer functionality associated with mapping between logical channels and transport channels, multiplexing of MAC SDUs onto TBs, demultiplexing of MAC SDUs from TBs, scheduling information reporting, error correction through HARQ, priority handling, and logical channel prioritization.

[0074] Channel estimates derived by the channel estimator 358 based on a reference signal or feedback sent by the base station 310 may be used by the TX processor 368 to select the appropriate coding and modulation schemes and to facilitate spatial processing. The spatial streams generated by the TX processor 368 may be provided to different antennas 352 via separate transmitters 354TX. Each transmitter 354TX may modulate an RF carrier with a corresponding spatial stream for transmission.

[0075] UL transmissions are processed at the base station 310 in a manner similar to that described in conjunction with the receiver functionality at the UE 350. Each receiver 318RX receives a signal through its respective antenna 320. Each receiver 318RX recovers information modulated onto an RF carrier and provides the information to a RX processor 370.

[0076] The controller / processor 375 may be associated with a memory 376 that stores program codes and data. The memory 376 may be referred to as a computer readable medium. In the UL, the controller / processor 375 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover IP packets from the UE 350. The IP packets from the controller / processor 375 may be provided to the EPC 160. The controller / processor 375 is also responsible for error detection using ACK and / or NACK protocols to support HARQ operations.

[0077] At least one of the TX processor 368, the RX processor 356, and the controller / processor 359 may be configured to combine Figure 1A The UE DTX component 198a and the active SR sending component 198b are used to perform various aspects.

[0078] At least one of the TX processor 316, the RX processor 370, and the controller / processor 375 may be configured to combine Figure 1A The NW DRX component 199a and the active SR receiving component 199b are used to perform various aspects.

[0079] When a UE performs discontinuous reception (DRX), the UE typically periodically monitors the radio channel for a physical downlink control channel (PDCCH) during an active or "on" duration, and powers down a large portion of its circuitry during an "off" duration to save battery life. A base station may configure a medium access control (MAC) entity of the UE via RRC configuration with DRX functionality that controls the UE's PDCCH monitoring activity for one of many radio network temporary identifiers (RNTIs) of the MAC entity in the PDCCH. RRC configuration can control DRX operation through multiple parameters, including, for example, the start duration timer (the duration at the beginning of the DRX cycle), the slot offset (the delay before starting the start duration timer), the inactivity timer (the duration after the PDCCH opportunity in which the PDCCH indicates a new uplink or downlink transmission for the MAC entity), the downlink retransmission timer (the maximum duration of each downlink HARQ process until a downlink retransmission is received), the uplink retransmission timer (the maximum duration of each uplink HARQ process until a grant for uplink retransmission is received), the long cycle start offset (the starting offset of the long DRX cycle and the subframe defining the start of the long and short DRX cycles), the optional short cycle (short DRX cycle) and the optional short cycle timer (the duration of the short DRX cycle that the UE should follow). When the UE is in RRC connected mode (RRC_CONNECTED) and if DRX is configured, the MAC entity of the UE may monitor the PDCCH non-continuously for all activated serving cells of the UE. Therefore, the UE can save power through non-continuous PDCCH monitoring. In addition, the service cells of the MAC entity can be configured via RRC configuration in two DRX groups with separate DRX parameters. When the RRC configuration does not configure a secondary DRX group, there is only one DRX group and all service cells of the MAC entity belong to the one group. When two DRX groups are configured, each service cell is uniquely assigned to either of the two groups.

[0080] Figure 4An example 400 of DRX reception at a UE is illustrated. The UE may monitor PDCCH 401 during a DRX On duration 402 within a DRX long cycle 404. The DRX long cycle may start at a time given by a DRX start offset 406, and the DRX On duration may start at a time given by a DRX slot offset 408. If the UE detects PDCCH 401 within the DRX On duration 402, the UE may continue to monitor for activity within a DRX Inactivity Timer 410. These and other DRX parameters may be configured to the UE in an RRC configuration from a base station.

[0081] When the UE is in a DRX on period and currently has data to be sent to the base station, the UE may send a scheduling request (SR) to the base station. The SR may inform the base station that the UE is requesting uplink shared channel (UL-SCH) resources for new uplink transmissions. For example, the UE may be triggered to send an SR in response to a buffer status report (BSR) process, a secondary cell (SCell) beam failure recovery, or a continuous listen-before-talk (LBT) failure recovery. The MAC entity of the UE may be configured with zero, one, or more SR configurations. The SR configuration may include a set of PUCCH resources for sending SRs across different bandwidth parts (BWPs) and cells of the UE. Typically, at most one PUCCH resource for sending an SR is configured per BWP for a logical channel, for SCell beam failure recovery, or for continuous LBT failure recovery. In addition, each SR configuration may correspond to one or more logical channels, SCell beam failure recovery, or continuous LBT failure recovery, each of which may be mapped to zero or one SR configuration configured by RRC.

[0082] The base station may configure at least the following parameters for the scheduling request process for each SR configuration: a prohibit timer (which prevents subsequent SR transmissions for a period of time after a given SR transmission) and a maximum number of SR transmissions. The UE may send an SR only on valid PUCCH resources, which may include PUCCH resources on a BWP that is active at the time of the SR transmission opportunity. The maximum number of SR configurations for each cell group of the UE is currently 8, and the maximum number of SR resources for each BWP in the cell is currently 8, but these maximum values ​​may change. The base station may also configure an SR resource configuration for each SR configuration, which indicates an SR periodicity that depends on the applied subcarrier spacing (SCS). For example, any of the following SR periodicities may be configured depending on the SCS, where "sym" refers to symbol and "sl" refers to time slot:

[0083] SCS=15kHz: 2sym, 7sym, 1sl, 2sl, 4sl, 5sl, 8sl, 10sl, 16sl, 20sl, 40sl, 80sl

[0084] SCS=30kHz: 2sym, 7sym, 1sl, 2sl, 4sl, 8sl, 10sl, 16sl, 20sl, 40sl, 80sl, 160sl

[0085] SCS=60kHz: 2sym, 7sym / 6sym, 1sl, 2sl, 4sl, 8sl, 16sl, 20sl, 40sl, 80sl, 160sl, 320sl

[0086] SCS=120kHz: 2sym, 7sym, 1sl, 2sl, 4sl, 8sl, 16sl, 40sl, 80sl, 160sl, 320sl, 640sl

[0087] Figure 5 An example 500 of a call flow between a UE 502 and a base station 504 is illustrated, in which the UE 502 sends an SR 506 to the base station 504. In response to, for example, a BSR procedure, SCell beam failure recovery, and continuous LBT failure recovery, the UE may send an SR to receive UL-SCH resources from the base station. After the UE sends the SR 506, the UE may trigger an inhibit timer for the SR. If the inhibit timer expires before the UE receives an UL grant 508 from the base station, the UE may resend the SR. The UE may continue with the maximum number of SR transmissions in the associated SR configuration in this manner. If the UE responds to, for example, a BSR procedure, SCell beam failure recovery, and continuous LBT failure recovery, the UE may send an SR to receive UL-SCH resources from the base station. Figure 5 If a UE receives a UL grant without the illustrated SR, the UE may continue to send data 510 in the resources indicated in the UL grant.

[0088] As an alternative to receiving a dynamic grant in response to an SR, the UE may receive a configuration grant, such as configuration grant type 1 or configuration grant type 2, from the base station. Configuration grant type 1 is an uplink grant provided by the base station to the UE via RRC configuration. The UE may store the uplink grant as a configuration uplink grant, and may therefore send data to the base station in resources associated with the configuration uplink grant. Configuration grant type 2 is an uplink grant provided by the base station to the UE via PDCCH (or other layer 1 signaling). For example, the base station may configure the uplink grant via RRC configuration, but activate or deactivate the uplink grant via DCI in the PDCCH. The UE may store the configuration uplink grant, and may therefore send data to the base station in resources associated with the configuration uplink grant when the uplink grant is active. The UE may clear the configuration uplink grant, and may therefore not send data to the base station in resources associated with the configuration uplink grant when the uplink grant is inactive.

[0089] The base station may configure configuration grant type 1 and configuration grant type 2 for each BWP via the RRC configuration for the UE's serving cell. In addition, multiple configurations may be active simultaneously in the same BWP. For configuration grant type 2, the base station may independently activate or deactivate configuration grants between the UE's serving cells. The MAC entity of the UE may be configured with both configuration grant type 1 and configuration grant type 2 for the same BWP. The maximum number of configuration grant configurations for each BWP is currently 12, but this maximum value may vary. The periodicity of configuration grant type 1 or configuration grant type 2 may depend on the applied SCS. For example, any of the following configuration grant periodicities may be configured in units of the number of symbols according to the SCS:

[0090] 15kHz: 2, 7, n*14, where n={1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640}

[0091] 30kHz: 2, 7, n*14, where n={1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 640, 1280}

[0092] 60kHz with normal CP 2, 7, n*14, where n={1,2,4,5,8,10,16,20,32,40,64,80,128,160,256,320,512,640,1280,2560}

[0093] 60kHz with the following ECPs: 2, 6, n*12, where n={1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 512, 640, 1280, 2560}

[0094] 120kHz: 2, 7, n*14, where n={1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 256, 320, 512, 640, 1024, 1280, 2560, 5120}

[0095] The UE may also receive BSR parameters from the base station via one or more RRC configurations that control the BSR and, therefore, the triggering of the SR. At least one of these BSR parameters may also depend on whether the configuration uplink grant is configured. For example, the UE may receive from the base station a logical channel configuration including a logical channel SR mask (which controls SR triggering when configuration grant type 1 or type 2 is configured) and an SR delay timer application flag (which indicates whether the delay timer is applied to the SR transmission of the logical channel when the delay timer is included in the BSR configuration, otherwise set to false), and receive from the base station a BSR configuration including an SR delay timer (which delays the transmission of the SR until the timer expires). The SR delay timer may be configured, for example, to any of the following number of subframes: 20, 40, 64, 128, 512, 1024, and 2560. The SR delay timer is different from the prohibit timer of the SR configuration (wherein the latter prohibits the transmission of subsequent SRs until the timer expires after the previous SR is transmitted). The inhibit timer may be configured, for example, to any of the following numbers of milliseconds: 1, 2, 4, 8, 16, 32, 64, 128.

[0096] Typically for uplink transmissions, the UE may receive an SR configuration or a configuration grant (CG) PUSCH (CG-PUSCH) configuration from the base station, such as configuration grant type 1 or configuration grant type 2. Each of these configurations may be associated with a set of opportunities for non-scheduled uplink transmissions by the UE to the base station. However, the UE may not typically utilize all of these opportunities, and since the base station has not dynamically granted these opportunities to the UE in response to the UE request, the base station may typically be uncertain of the opportunities that the UE will actually use for uplink transmissions. Therefore, the base station tends to actively and blindly monitor whether all of these opportunities are used by the UE, resulting in significant energy consumption at the base station. Since many of these opportunities may not ultimately be used, the base station wastes significant energy to monitor many of these opportunities. In addition, since the number of opportunities associated with SR or CG-PUSCH transmissions may be large (e.g., with a periodicity of at least every two symbols), energy efficiency is significantly reduced. Therefore, it would be helpful to allow the base station to minimize blind monitoring of SR or CG-PUSCH transmission opportunities to improve the energy efficiency of the base station and achieve network energy savings.

[0097] Fig. 6A and Figure 6B Examples 600, 650 of SR opportunities 602 and CG-PUSCH opportunities 652 that base stations 604, 654 can configure for UEs 606, 656 are illustrated, respectively. Fig. 6A In the example of , the base station 604 may provide an SR configuration and an SR resource configuration for a logical channel, which indicates the resources or SR opportunities 602 at which the UE 606 can send an SR in response to a BSR for the logical channel, SCell beam failure recovery, or continuous LBT failure recovery. The base station 604 may also provide a logical channel configuration and a BSR configuration, which indicates whether the logical channel SR mask is enabled (in which case the SR opportunities 602 will be masked and thus SR transmissions in those opportunities are prohibited) or whether the SR delay timer is applicable (in which case the SR opportunities 602 and thus transmissions will be delayed until the timer expires). Similarly, in Figure 6B In the example of , the base station 654 may provide a CG-PUSCH configuration (such as configuration grant type 1 or configuration grant type 2) indicating resources or CG-PUSCH opportunities 652 in which the UE 656 may send uplink data (depending on the activation of the CG-PUSCH opportunity 652 in the DCI if configuration grant type 2 is configured). Fig. 6A In the example of , the SR resource configuration may configure the SR opportunity 602 to have a periodicity 608 (eg, two symbols), and Figure 6BIn the example of , the configuration grant configuration may configure the CG-PUSCH opportunity 652 to have a periodicity 658 (eg, two symbols).

[0098] like Fig. 6A As illustrated in the example of , the base station 604 may monitor for an SR 610 from the UE 606 in each of the SR opportunities 602. If the base station 604 receives the SR 610 in any of these opportunities, the base station may send a dynamic grant 612 to the UE 606 that configures resources 614 for the UE 606 to apply to uplink transmissions 616. However, typically, the UE 606 may send the SR 610 in infrequent opportunities, such as Fig. 6A As illustrated in . Thus, the base station 604 may waste energy to monitor many configured opportunities because, as illustrated in monitoring time 618, the base station may not receive the SR in these monitored opportunities. Similarly, Figure 6B As illustrated in the example of , the base station 654 may monitor the uplink transmission 660 from the UE 656 in each CG-PUSCH opportunity 652. However, typically the UE 656 may send the uplink transmission 660 in infrequent opportunities, such as Figure 6B Thus, the base station 654 may waste energy monitoring many configured occasions because, as illustrated at monitoring time 662, the base station may not receive an uplink transmission during these monitored occasions.

[0099] One way to provide energy saving to the base station 604, 654 is that the base station will configure the infrequent SR or CG-PUSCH resources to have a large periodicity, for example, via its RRC configuration. Due to the large periodicity, the base station 604, 654 can reduce the amount of monitoring time 618, 662, so that the base station can perform monitoring in fewer opportunities of the SR opportunity 602 or CG-PUSCH opportunity 652, thereby saving energy. However, this approach may significantly affect the UE uplink latency, because its SR 610 or uplink transmission 616, 660 will be delayed as a result.

[0100] Another way that energy savings can be provided to the base stations 604, 654 is that the base station will dynamically activate or deactivate the timing for UE uplink transmissions via layer 1 signaling. For example, for configuration grant type 2, the base station may send a DCI to deactivate the CG-PUSCH timing 652 until the base station later sends another DCI to reactivate the CG-PUSCH timing 652. Fewer opportunities for CG-PUSCH opportunities 652 caused by deactivation will cause the base station to perform less monitoring, thereby saving energy. However, this deactivation and reactivation is generally limited to configuration grant type 2, and therefore it would be helpful if this energy saving could be applied to SR and configuration grant type 1 as well as configuration grant type 2. Additionally, the deactivation and reactivation of configuration grant type 2 are binary operations with limited flexibility, and therefore it would be helpful if more flexible options for deactivation and reactivation of SR opportunities or CG-PUSCH opportunities could be applied.

[0101] In order to flexibly provide more energy savings at the base station, in one example, the base station may dynamically activate or deactivate the SR configuration and thus the SR transmission via DCI, MAC-CE, or other layer 1 (L1) or layer 2 (L2) signaling. For example, after the base station configures the SR configuration for the UE via RRC configuration, the base station may send a message to the UE activating or deactivating the SR configuration via L1 or L2 signaling. For example, the message may include a bit that activates or deactivates the SR configuration for the logical channel based on whether the bit is 0 or 1. In another example, after the base station configures the SR resource configuration for the UE via RRC configuration, the base station may send a message to the UE activating or deactivating the SR resource configuration via L1 or L2 signaling. For example, the message may include a bit that activates or deactivates the SR resource configuration for the SR configuration based on whether the bit is 0 or 1. The message to activate or deactivate the SR resource configuration may be the same message or a different message from the message to activate or deactivate the SR configuration. In addition, the base station may activate or deactivate multiple SR configurations in one or more messages, or activate or deactivate multiple SR resource configurations in one or more messages.

[0102] Figure 7An example 700 of an SR resource configuration 702 that a base station 704 may configure for a UE 706 is illustrated. In the illustrated example, the base station configures two SR resource configurations indicating different periodicities or offsets of SR opportunities 708, but in other examples, the base station may configure a different number of SR resource configurations. Initially or by default, the SR resource configuration 702 and therefore the SR opportunities 708 may be deactivated so that the UE 706 does not initially send SRs in the configured opportunities. After the base station 704 provides an activate resource message 710 for SR resource configuration 1 and an activate resource message 712 for SR resource configuration 2, both of which indicate that the associated SR resource configurations are active, the SR opportunities 708 corresponding to the active SR resource configurations may be monitored for SR transmissions, such as Figure 7 as illustrated. The multiple activation resource messages provided here are merely examples; in other examples, a single message may be provided to activate both SR resource configurations or to activate only one SR resource configuration. Alternatively, in other examples, the SR resource configuration 702 and therefore the SR opportunity 708 may be activated by default, rather than being deactivated by default, in which case no activation resource message would initially be provided. When the SR opportunity 708 is active, the UE may send an SR in each of the SR opportunities, and the base station may monitor each of the opportunities for SR transmissions from the UE. Later in this example, the base station 704 may provide a deactivation resource message 714 for SR resource configuration 1, indicating that the associated SR resource opportunity is inactive and therefore the SR opportunity 708 corresponding to SR resource configuration 1 may no longer be monitored for SR transmissions. Therefore, for SR transmissions, only the SR opportunities 708 corresponding to the remaining active SR resource configurations may be applied and monitored, such as Figure 7 As illustrated, energy saving is provided at the base station.

[0103] The base station may also or alternatively configure parameters associated with SR configuration or SR resource configuration in a message or L1 / L2 signaling for activating or deactivating SR transmission. In one example, the message may specify a duration for activating or deactivating SR transmission, which may be expressed in time units or in the number of SR opportunities. For example, the message may indicate that the UE may send an SR or refrain from sending any SR within a certain time period or a given number of SR opportunities. Therefore, as Figure 7 In an alternative to the example of , the activate resource message 710 (or a different message) may indicate, for example, that the active duration spans a maximum of six SR opportunities, after which the SR resource configuration 1 may be switched to inactive (without transmitting the deactivate resource message 714). In another example, the message may modify an inhibit timer associated with the SR configuration. For example, the message may start, restart, or stop an inhibit timer associated with the SR configuration in order to control the timing of subsequent SR transmissions. Thus, as Figure 7As an alternative to the example of , the activate resources message 710 (or a different message) may indicate that the inhibit timer is periodically stopped and restarted after each SR opportunity 708 to effectively increase the SR opportunity periodicity to match the periodicity of SR resource configuration 2 and thereby deactivate any SR transmissions that would otherwise be sent at the initial SR opportunity periodicity.

[0104] In another example, the message may modify the logical channel parameters associated with the SR configuration. For example, the message may enable, disable or delay the triggering of SR transmission when data is available for the logical channel, for example by switching the logical channel SR mask or SR delay timer application flag, or by starting, restarting or stopping the SR delay timer for the SR configuration. Figure 7 As an alternative to the example, the activate resources message 710 (or a different message) may indicate starting a SR delay timer so that the initial SR timing for SR resource configuration 1 coincides in time with the initial SR timing for SR resource configuration 2, thereby deactivating any SR timings for SR resource configuration 1 that would otherwise exceed those SR timings for SR resource configuration 2 in the initial configuration.

[0105] In the foregoing examples, activation and deactivation may be specific to one configuration or transmission, or activation and deactivation may apply to multiple SR configurations or transmissions. Figure 7 As illustrated in the example of , base station 704 may transmit one message, activation resource message 710, specifically activating or deactivating SR resource configuration 1, and another message, activation resource message 712, specifically activating or deactivating SR resource configuration 2. However, in alternative examples, activation resource message 710 or 712 may activate or deactivate both SR resource configurations 1 and 2. Similarly, in the aforementioned examples, activation and deactivation may be specific to one UE, or activation and deactivation may be multicast or broadcast signaled to a cell including multiple UEs. For example, as Figure 7 Alternatively to the example of , the deactivate resources message 714 may be broadcast to multiple UEs including UE 706, informing these UEs that the base station 704 will not monitor SR resource configuration 1 for SR transmissions from any associated UE (not just UE 706).

[0106] Typically, for logical channels, SCell beam failure recovery, or continuous LBT failure recovery, the base station may configure at most one PUCCH resource for SR for each BWP. Therefore, if the base station is to deactivate the PUCCH resources for SR for a given BWP according to any of the aforementioned examples, the UE may not have any valid resources to send SR on the same BWP during deactivation. Therefore, the base station can relax this restriction by configuring multiple PUCCH resources for SR on a given BWP. For example, the base station may allow the UE to send SR in multiple PUCCH resources on a BWP in response to the data availability of logical channels associated with SR, SCell beam failure recovery, or continuous LBT failure recovery. Therefore, even if the base station deactivates one PUCCH resource for SR, SR may have at least one other PUCCH resource available for the UE to apply.

[0107] In other examples, the base station may not activate or deactivate the SR opportunity, but may reconfigure the SR opportunity using L1 / L2 signaling. For example, when the base station configures the SR resource configuration via RRC configuration, the base station may dynamically modify the parameters of the SR resource configuration in the DCI, MAC-CE, or using some other L1 / L2 signaling. Such parameters may include, for example, the periodicity and offset of the SR opportunity. Therefore, as Figure 7 Alternatively to the example of , the activate resources message 710 may modify the periodicity initially configured in SR resource configuration 1 to match the periodicity of SR resource configuration 2, thereby reconfiguring SR resource configuration 1 to produce fewer SR opportunities and thus greater base station energy savings.

[0108] In any of the foregoing examples, the base station may indicate via L1 / L2 signaling the time at which activation, deactivation, or reconfiguration of an SR configuration, SR resource configuration, logical channel configuration, BSR configuration, or other SR-associated configuration takes effect. For example, the base station may provide DCI, MAC-CE, or other L1 / L2 signaling that notifies the UE not only about the activation, deactivation, or reconfiguration of the SR opportunity, but also about the time delay until the activation, deactivation, or reconfiguration begins. Thus, as Figure 7 As an alternative to the example, in addition to activating the SR opportunity 708 for SR resource configuration 1, the activation resource message 710 may also indicate that the activation will occur a number of symbols, time slots, subframes, SR opportunities or other time units after the transmission of the activation resource message 710, thereby delaying the occurrence of the initial SR opportunity until that time unit has passed and further saving base station energy due to reduced monitoring.

[0109] In any of the foregoing examples, the base station may dynamically activate, deactivate, or reconfigure the SR configuration or SR-associated configuration based on one or more UE capabilities. For example, the UE may indicate to the base station in a capability information message that the UE is capable of activating, deactivating, or reconfiguring the SR configuration, and the base station may configure and send activation, deactivation, or reconfiguration of the SR configuration DCI, MAC-CE, or other L1 / L2 signaling from the base station in response to the indicated UE capabilities according to any of the foregoing examples. Therefore, as Figure 7 Alternatively to the example of , the base station 704 may send an activate resources message 710 to the UE 706 to activate the SR opportunity 708 in the SR resource configuration 1 in response to the UE 706 previously indicating an ability to handle such messages from the base station.

[0110] Although the foregoing examples specifically relate to SR and associated configurations, it should be understood that these examples are not limited to SR. For example, the above concepts may be similarly applicable to configuration grant type 1 and configuration grant type 2. For example, the base station may provide one or more messages to the UE via L1 / L2 signaling that activates, deactivates, or reconfigures the CG-PUSCH opportunity associated with the configuration grant configuration provided to the UE via RRC configuration. The message may activate, deactivate, or reconfigure the CG-PUSCH opportunity in a manner similar to that previously described for the SR opportunity (e.g., by modifying similar parameters used for the configuration grant).

[0111] In addition to dynamically activating SR or configuring a grant configuration via L1 / L2 signaling or as an alternative thereto, the base station may provide a semi-static discontinuous transmission (DTX) configuration to the UE to provide similar energy savings at the base station. In one example, the DTX configuration may be a UE DTX configuration, based on which the UE periodically operates in a sleep mode when it is not expected to transmit during a periodic interval to save transmit power. The base station may suppress monitoring UE transmissions during these periodic intervals to achieve network energy savings. In another example, the DTX configuration may be a cell DRX configuration, based on which the base station periodically operates in a sleep mode when it is not expected to transmit during a periodic interval to save receive power. The base station may stop supplying power to its radio frequency (RF) chain or RF components such as its antenna, transmitter, receiver, or transceiver during these periodic intervals to similarly achieve network energy savings. In response to receiving the DTX configuration, the UE may transmit in valid resources falling within the active interval indicated in the DTX configuration, and suspend transmission outside these intervals. For example, the UE may send SRs, uplink data in CG-PUSCH opportunities, and other uplink data during an active or on duration, and refrain from sending such information during an inactive or off duration.

[0112] When the DTX cycle is in the off duration, the base station may not monitor the SR opportunity or the CG-PUSCH opportunity, thereby saving energy. When the DTX cycle is in the on duration, the base station may apply any of the aforementioned example concepts of activation, deactivation, and reconfiguration regardless of the DTX configuration to save additional power at the base station. For example, the base station may apply the Figure 7 Any of the concepts described in the aforementioned examples of the present invention may be used to activate, deactivate or reconfigure SR, CG-PUSCH or other uplink transmissions during the on duration of a DTX cycle. Alternatively, when the DTX cycle is in the on duration, the base station may maintain the SR or CG-PUSCH opportunity without performing any deactivation or reconfiguration, because the DTX configuration alone can be used to improve base station energy saving. In addition, the base station may activate, deactivate or reconfigure the SR configuration, CG-PUSCH configuration or other uplink configuration relative to the DTX configuration. For example, the base station may semi-statically or dynamically indicate whether a general SR, a SR associated with a specific SR configuration, a general CG-PUSCH transmission, a CG-PUSCH transmission associated with a specific CG configuration, a random access channel (RACH) transmission or other uplink transmission may be deactivated from DTX and therefore may be transmitted during the off duration of the DTX cycle, or activated for DTX and therefore may not be transmitted during the off duration of the DTX cycle.

[0113] Figure 8 An example 800 is illustrated of an SR opportunity 802 and a CG-PUSCH opportunity 804 (for one configuration grant type 1 and another configuration grant type 2) that a base station 806 can configure for a UE 808 via an SR configuration and a configuration grant configuration, respectively. In this example, the base station 806 also provides the UE 808 with a DTX configuration 810 that specifies an on duration 812 and an off duration 814 of a DTX cycle 816 and a delay 818 before the on duration 812 begins. During the on duration 812, depending on the Figure 7 The UE may send data during the SR opportunity 802 and the CG-PUSCH opportunity 804 to save base station energy. The UE may also send other data in addition to SR or CG-PUSCH data during the on duration 812, such as RACH signals or other uplink data. Figure 8 The example of illustrates a single DTX configuration associated with different uplink transmission configurations (such as SR configuration, type 1CG configuration, and type 2CG configuration), but in other examples, different DTX configurations with consistent DTX cycles may be associated with different uplink transmission configurations, respectively. In addition, the UE DRX configuration (not shown) may also have a DRX cycle consistent with the DTX cycle 816.

[0114] Typically, during the OFF duration 814, the UE cannot send data in these opportunities, and therefore the base station cannot monitor any of the SR opportunities 802 or CG-PUSCH opportunities 804 that fall within the OFF duration 814. The base station can refrain from monitoring opportunities during Figure 8 810 are illustrated as masking opportunities with dashed lines. Thus, further energy savings at the base station can be achieved by applying DTX. However, this behavior of the UE and the base station can be changed semi-statically or dynamically according to any activation, deactivation or reconfiguration of the DTX configuration 810 relative to these opportunities or configurations, or according to any activation, deactivation or reconfiguration of the DTX configuration 810 itself. For example, Figure 8 One or more rows of opportunities in (such as those specifically corresponding to SR configurations and Type 1 CG configurations) may alternatively be replaced with solid lines in the figure (not masked) and thus be subject to base station monitoring even during the off duration 814 when these particular configurations are semi-statically or dynamically deactivated for DTX. Similarly, Figure 8 The timings or general uplink transmissions of each row in the figure may alternatively be replaced by solid lines (not masked) in the figure and thus be subject to base station monitoring even during the shutdown duration 814 when the DTX configuration 810 itself is semi-statically or dynamically deactivated. Therefore, if the base station provides an RRC configuration, MAC-CE or DCI that deactivates the general DTX configuration 810 or deactivates (generally or by configuration) specific uplink transmissions with respect to one or more DTX configurations 810, the UE and the base station may ignore whether the timings 802, 804 associated with these deactivated uplink transmissions fall within the shutdown duration 814 when performing uplink transmission and monitoring, respectively. On the other hand, if the base station provides an RRC configuration, MAC-CE or DCI that activates the general DTX configuration 810 or activates (generally or by configuration) specific uplink transmissions with respect to one or more DTX configurations 810, the UE and the base station may refrain from performing uplink transmission and monitoring, respectively, in the timings 802, 804 associated with these activated uplink transmissions within the shutdown duration 814.

[0115] In one example, the DTX configuration 810 provided by the base station to the UE may include at least one of the following parameters: the time when the DTX cycle 816 starts (e.g., a subframe or other DTX start offset), the on duration 812 within which the UE 808 can send uplink data on valid resources, the off duration 814 within which resources for uplink transmissions of the UE 808 are masked, the delay 818 before starting the on duration 812 within the DTX cycle 816 (e.g., a DTX slot offset), and the duration or periodicity of the DTX cycle 816. The DTX configuration 810 may also include multiple DTX cycles, such as a long DTX cycle and a short DTX cycle. For example, as Figure 8Alternatively to the example of , DTX configuration 810 may configure a long DTX cycle corresponding to DTX cycle 816 (having equal to Figure 8 816) and a short DTX cycle that is less than the long DTX cycle and activated in response to activity within the long DTX cycle's on duration 812. The short DTX cycle may last for a configured time duration, after which, if no activity occurs within the on duration, the DTX cycle may revert to the long DTX cycle.

[0116] In various examples, the DTX configuration may be associated with one or more types of transmissions of the UE. In one example, the DTX configuration may be associated with an SR transmission of the UE. For example, referring to Figure 8 , according to the semi-static or dynamic DTX activation or deactivation of general SR transmission, the DTX configuration 810 can configure the UE 808 to transmit any SR for any SR configuration in any SR opportunity within the on duration 812 but not within the off duration 814. In another example, the DTX configuration can be associated with SR transmission related to the SR configuration or SR resource configuration of the UE. For example, as Figure 8 In an alternative embodiment of the example, according to the semi-static or dynamic DTX activation or deactivation of a specific SR or SR resource configuration, the DTX configuration 810 may configure the UE to transmit an SR for at least one specific SR configuration or SR resource configuration (but not in other unspecified SR configurations or SR resource configurations of the UE) in the associated SR opportunities within the on duration 812 but not within the off duration 814. In another example, the DTX configuration may be associated with the CG-PUSCH transmission of the UE. For example, referring to Figure 8 , according to semi-static or dynamic DTX activation or deactivation of general CG-PUSCH transmissions, the DTX configuration 810 may configure the UE 808 to transmit uplink data in response to a configuration grant configured for any configuration grant in any CG-PUSCH opportunity within the on duration 812 but not within the off duration 814. In another example, the DTX configuration may be associated with a CG-PUSCH transmission with respect to a configuration grant configured for the UE. For example, as Figure 8In an alternative embodiment of the example, according to semi-static or dynamic DTX activation or deactivation of a specific CG configuration, the DTX configuration 810 may configure the UE 808 to send uplink data in response to a configuration grant for at least one specific configuration grant configuration (but not for other unspecified configuration grant configurations of the UE) in an associated CG-PUSCH opportunity within an on duration 812 but not within an off duration 814. The specific configuration grant configuration applicable to DTX may be associated with, for example, any configuration grant type 1, specific configuration grant type 1 (but not other unspecified configuration grant type 1), any configuration grant type 2, or specific configuration grant type 2 (but not other unspecified configuration grant type 2), or a combination of any of the foregoing.

[0117] In another example, the DTX configuration may be associated with the RACH transmission of the UE. Figure 8 In an alternative embodiment of the example, the DTX configuration 810 may configure the UE 808 to transmit RACH signals during the on duration 812 but not during the off duration 814, depending on the semi-static or dynamic DTX activation or deactivation of the RACH transmission. In another example, the DTX configuration may be associated with the general uplink transmission of the UE. For example, as Figure 8 In an alternative to the example of , the DTX configuration 810 may configure the UE 808 to transmit any uplink data (e.g., PUCCH data or PUSCH data) within the on duration 812 but not within the off duration 814, depending on the semi-static or dynamic DTX activation or deactivation of the general uplink transmission or the DTX configuration itself. In another example, the DTX configuration may be associated with a combination of any of the aforementioned transmissions (e.g., SR, CG-PUSCH, RACH, general UL, etc.). In any of the aforementioned examples, the DTX configuration may be a dedicated RRC configuration for DTX including parameters for SR, configuration grant, etc., or the DTX configuration may be a sub-configuration or information element for DTX within another configuration for associated transmission (e.g., a DTX information element within an SR configuration, an SR resource configuration, a configuration grant configuration, etc., etc.).

[0118] In one example, the DTX configuration may be associated with a communication resource used for uplink transmission of the UE. The communication resource may be, for example, a BWP, one or more serving cells, a serving cell group, a frequency range, or a combination thereof. Figure 8Alternatively to the example of , the DTX configuration 810 may configure the UE 808 to transmit SR, CG-PUSCH data, RACH signal, PUCCH data, PUSCH data, or other uplink data in at least one specific BWP (but not for other unspecified BWPs), in one or more specific serving cells (but not for other unspecified serving cells), in at least one specific serving cell group (but not for other unspecified serving cell groups), in at least one specific frequency range (but not for other unspecified frequency ranges), or a combination of any of the above during the on duration 812 but not during the off duration 814. In any of the foregoing examples, the DTX configuration may be a dedicated RRC configuration for DTX including parameters for BWP, serving cell, serving cell group, frequency range, etc., or the DTX configuration may be a sub-configuration or information element for DTX within another configuration for associated transmission (e.g., a DTX information element within a BWP configuration, a cell configuration, a frequency range configuration, etc.).

[0119] In some examples, the UE may apply multiple DTX configurations, or a DTX configuration and a DRX configuration. For example, the base station may configure the UE to apply one DTX cycle with one periodicity or other parameters for SR and another DTX cycle with different periodicity or other parameters for configuration grants, or to apply a DTX cycle with one periodicity or other parameters for uplink data and a DRX cycle with different periodicity or other parameters for downlink data. In the former case (two DTXs), the base station can minimize the active time of the UE by making the DTX configuration or DTX cycle consistent. For example, as Figure 8 As an alternative to the example of , the base station 806 may configure multiple DTX configurations 810 including one DTX configuration for the SR opportunity 802 and one DTX configuration for the CG-PUSCH opportunity 804, so that the on duration 812 of the DTX cycles 816 in the corresponding DTX configurations are consistent. Similarly, in the latter case (DTX and DRX), the base station can minimize the active time of the UE by making the DTX configuration and the DRX configuration of the UE consistent. For example, as Figure 8 As an alternative to the example of , the base station 806 may also configure a DRX configuration for the UE 808 together with the DTX configuration 810, so that the start duration 812 of the DTX cycle 816 in the DTX configuration is consistent with the start duration of the DRX cycle in the DRX configuration.

[0120] In another example, the base station may configure the time extension of the on-duration of the DTX and DRX cycles according to the network traffic pattern. For example, the base station may define the extension of the active time for the DTX cycle based on the occurrence of downlink or uplink activity during the active time of the DTX cycle. The activity may include, but is not limited to, the reception of PDSCH or PDCCH data, the transmission of PUSCH or PUCCH data, and the reception of HARQ feedback that triggers retransmission (e.g., generating a NACK for a downlink or uplink grant without switching a new data indicator (NDI). For example, as Figure 8 Alternatively to the example of , the base station 806 may configure the DTX configuration 810 to include a time extension parameter such as an inactivity timer that indicates how long the length of the on duration 812 is extended in response to data or HARQ feedback transmitted or received by the UE during the on duration 812. Similarly, the base station may define an extension of the active time for the DTX cycle based on the occurrence of downlink or uplink activity during the active time of the UE's DRX cycle. For example, as Figure 8 As an alternative to the example of , the base station 806 may configure the DRX configuration for the UE 808 with its own DRX on duration and off duration in addition to the DTX configuration 810. The base station 806 may configure the DTX configuration 810 to include a time extension parameter such as an inactivity timer that indicates how long to extend the length of the on duration 812 of the DTX cycle 816 in response to the UE transmitting or receiving data or HARQ feedback during the DRX on duration.

[0121] In one example, similar to the SR configuration, SR resource configuration, and configuration grant configuration, the base station may dynamically activate or deactivate the DTX configuration via L1 or L2 signaling. For example, the base station 806 may send a DCI, MAC-CE, or other L1 or L2 message indicating to the UE 808 that the DTX configuration 810 is active, in response to which the UE and the base station may apply the DTX cycle 816. Later, the base station may send a similar message indicating to the UE 808 that the DTX configuration 810 is inactive, in response to which the UE may no longer apply the DTX cycle 816. The base station may activate or deactivate the DTX configuration in a manner similar to the activation or deactivation of the SR configuration, SR resource configuration, or configuration grant configuration indicated in the above examples. The base station may similarly activate or deactivate the DTX configuration in a semi-static manner via RRC or layer 3 signaling. Alternatively or additionally, the base station may semi-statically or dynamically activate or deactivate the SR configuration, SR resource configuration, configuration grant configuration, or other uplink transmission configuration in a similar manner relative to the DTX configuration 810.

[0122] In one example, the base station may apply L1 or L2 signaling to interrupt or cancel the first active time indicated by the DTX configuration. For example, the base station may send a DCI, MAC-CE, or other L1 or L2 message notifying the UE to stop applying DTX during the on duration of the initial DTX cycle. For example, as Figure 8 As an alternative to the example of , the base station 806 may send a DCI, MAC-CE, or other L1 or L2 message to indicate to the UE 808 that at least a portion of the turn-on duration 812 is not to be applied during the initially configured DTX cycle and therefore no uplink data is to be sent during that portion or duration until the next DTX cycle.

[0123] In one example, the base station may reconfigure the parameters of the DTX configuration via L1 or L2 signaling. For example, the base station may send a DCI, MAC-CE, or other L1 or L2 message that modifies at least one of the DTX start offset, on duration, off duration, delay, periodicity, or other parameters of the DTX configuration. Figure 8 Alternatively to the example of , base station 806 may send a DCI, MAC-CE, or other L1 or L2 message that reconfigures delay 818 to be longer or shorter than illustrated, reconfigures on duration 812 or off duration 814 to be longer or shorter than illustrated, reconfigures to have a different periodicity of DTX cycle 816, or reconfigures to include some other reconfiguration.

[0124] In one example, the base station may define one or more UE capabilities for supporting one or more DTX configurations. For example, the base station may provide a DTX configuration to the UE in response to identifying from a capability information message from the UE that the UE is capable of applying DTX. For example, as Figure 8 In an alternative to the example of , the UE 808 may initially send a capability information message to the base station 806, the capability information message indicating that the UE is capable of supporting general DTX, DTX for general SR configuration or for specific SR configuration, DTX for general configuration grant configuration or for specific configuration grant configuration, DTX for RACH signals, DTX for general uplink signals, DTX for specific BWP, DTX for specific serving cells, DTX for specific serving cell groups, DTX for specific frequency ranges, etc. through one or more UE capabilities. In response to receiving the capability information message and determining that the UE is capable of, for example, general DTX, the base station 806 may configure the DTX configuration 810 and provide the DTX configuration to the UE 808 accordingly.

[0125] In another example, the base station may indicate at least one parameter of the DTX configuration via a system information block (SIB) or multicast signaling. For example, the base station may indicate at least one of the DTX start offset, on duration, off duration, delay, periodicity, or other parameters of the DTX configuration in a SIB broadcast to UEs in a serving cell or in a multicast or groupcast message to certain UEs. Figure 8 Alternatively to the example of , the base station 806 may initially notify the UE 808 of at least one parameter of the DTX configuration 810, such as the delay 818, the on duration 812, or the off duration 814, via a SIB or multicast message to the UE 808 and other UEs.

[0126] Fig. 9 An example 900 of a call flow diagram between a UE 902 and a base station 904 is illustrated. Initially, the UE 902 may send a capability information message 906 indicating a UE capability to support activation, deactivation, or reconfiguration of an SR configuration, a configuration grant configuration, a DTX configuration, a DRX configuration, or other configurations, or activation, deactivation, or reconfiguration of parameters of such configurations. After receiving the capability information message 906, the base station 904 may send one or more SR configurations 908 and SR resource configurations 910 to the UE 902. The SR configuration 908 may include a plurality of parameters, including at least a prohibition timer and a maximum number of SR transmissions. The SR configuration 908 or the SR resource configuration 910 may also be associated with a PUCCH resource for a BWP. In addition, the base station 904 may send one or more configuration grant configurations 912 to the UE 902. The configuration grant configuration 912 may be used to configure grant type 1, configure grant type 2, or both. The base station 904 may also send one or more logical channel configurations 914 to the UE 902. The logical channel configuration 914 may indicate a logical channel associated with a corresponding SR configuration, and a transmission state of the corresponding SR indicating whether the SR is enabled, disabled, or delayed.

[0127] The base station 904 may then send a message 916 to the UE 902 that may activate, deactivate, or reconfigure any of the aforementioned configurations or parameters in these configurations regardless of or independently of the DTX configuration. The message 916 may be, for example, a message to dynamically activate, deactivate, or reconfigure an SR configuration, a CG-PUSCH configuration, or a message such as a message about a DTX configuration. Figure 7 Alternatively, message 916 may be a semi-static activation, deactivation or reconfiguration of SR configuration, CG-PUSCH configuration or other uplink transmission configuration such as DCI or MAC-CE. Figure 7RRC configuration of other uplink transmission configurations described. In one example, message 916 may indicate one or more activity states of the corresponding SR configuration indicating whether the corresponding SR configuration is active or inactive. In another example, message 916 may indicate the duration of the active state of the SR configuration. In another example, message 916 may modify the timer state of the prohibition timer in the corresponding SR configuration. In another example, message 916 may modify the transmission state of the corresponding logical channel configuration. In another example, message 916 may reconfigure one or more parameters in the corresponding SR configuration or SR resource configuration. In another example, message 916 may indicate the action time of the corresponding SR configuration, which indicates when the activity state or reconfiguration of the corresponding SR configuration takes effect. In any of the foregoing examples, message 916 may activate, deactivate or reconfigure the corresponding SR configuration or SR resource configuration based on UE capabilities. In other examples, message 916 may also indicate, modify or reconfigure parameters similar to any of the foregoing parameters in the configuration grant configuration based on UE capabilities in some cases.

[0128] The base station 904 may also send a DTX configuration 918 to the UE 902. The DTX configuration 918 may be sent in the same message as the SR configuration, CG configuration, or other UE transmission configuration, or in a different message. In one example, the DTX configuration 918 may indicate the resources used for UE transmission (such as SR or CG-PUSCH) and the active time duration used for UE transmission in UE DTX or cell DRX. In another example, the DTX configuration 918 may indicate at least one of the following: the start time of the DTX cycle, the active time duration during the DTX cycle, the inactive time duration during the DTX cycle, the time delay before the start time of the DTX cycle, or the duration or periodicity of the DTX cycle. In one example, the DTX configuration 918 may indicate multiple DTX cycles, such as a long DTX cycle and a short DTX cycle. In one example, the DTX configuration 918 may be associated with at least one of: an SR transmission of the UE 902, an SR transmission associated with an SR configuration or an SR resource configuration of the UE 902, a CG-PUSCH transmission of the UE 902, a RACH transmission of the UE 902, a (general) uplink transmission of the UE 902, or a combination of any of the foregoing. In one example, the DTX configuration 918 may be associated with an uplink transmission of the UE in a communication resource, the communication resource comprising at least one of a BWP, one or more serving cells, a serving cell group, a frequency range, or a combination of any of the foregoing. In one example, the DTX configuration 918 may indicate a time extension of an active time duration of a DTX cycle, and the time extension may be triggered at the UE in response to uplink or downlink activity during the active time duration.

[0129] In one example, the base station 904 may send another DTX configuration 920 to the UE 902. The DTX configuration 920 may indicate the same parameters (although different values) as the DTX configuration 918. In one example, the DTX configuration 920 may be associated with the uplink transmission of the UE 902 and indicate the active time duration of the UE DTX or cell DRX, and the base station 904 may configure the active time durations of the DTX configurations 918 and 920 to be consistent.

[0130] In one example, the base station 904 may send a DRX configuration 922 to the UE 902. The DRX configuration 922 may include at least one of a DRX start offset, a DRX slot offset, a DRX active time duration or on duration, a DRX inactivity timer, and other parameters. In one example, the DRX configuration 922 may indicate a DRX active time duration of the UE DRX, and the base station 904 may configure an active time duration of the DTX configuration 918 to be consistent with the DRX active time duration of the DRX configuration 922. In one example, the DRX configuration 922 may indicate a DRX active time duration, the DTX configuration 918 may indicate a time extension of the active time duration of the DTX cycle, and the time extension may be triggered in response to uplink or downlink activity during the DRX active time duration.

[0131] In various examples, base station 904 can send message 924 to UE 902. Message 924 can be associated with DTX configuration 918. In one example, message 924 can be a semi-static indication (such as RRC configuration) or a dynamic indication (such as DCI or MAC-CE) of the DTX configuration or general UE transmission relative to the activity status of the DTX configuration, such as regarding Figure 8 For example, the message 924 may indicate a DTX activity status of the DTX configuration 918, 920, which indicates whether the DTX configuration 918, 920 is active or inactive. In some examples, the message 924 may be a semi-static indication or a dynamic indication of the activity status of a particular UE transmission or a particular uplink transmission configuration relative to the DTX configuration, such as also regarding Figure 8As described. For example, message 924 may indicate the activity status of an SR configuration, an SR resource configuration, a CG configuration, a logical channel configuration, a RACH configuration, or other UE transmission configuration relative to one or more DTX configurations 918, 920. In one example, the DTX configuration 918 may indicate multiple DTX cycles, and the message 924 may interrupt or cancel an initial DTX cycle in the multiple DTX cycles. In one example, the DTX configuration 918 may include parameters for UE transmission, and the message 924 may reconfigure the parameters. In one example, the message 924 may activate, deactivate, or reconfigure the DTX configuration 918 based on UE capabilities. In one example, the message 924 may indicate parameters associated with the DTX configuration, and the message 924 may be a SIB or multicast message for multiple UEs including the UE 902.

[0132] In response to receiving the aforementioned configuration and messages, the UE 902 may send a SR 926, a CG-PUSCH 928, or an uplink transmission 930 (eg, a RACH signal, PUCCH data, PUSCH data, or other uplink data) accordingly.

[0133] Fig.10 1000 is a flow chart of a method of wireless communication. The method may be performed by a UE (e.g., UE 104, 350, 502, 606, 656, 706, 808, 902; device 1202). Optional aspects are illustrated by dashed lines. The method allows the UE to send an SR or other uplink transmission to a network entity such as a base station in UE DTX or cell DRX according to a message indication of dynamic activation, deactivation or reconfiguration of a DTX configuration, an SR configuration or other uplink transmission configuration, so as to provide energy saving at the base station.

[0134] At 1002, the UE may receive an SR configuration associated with an SR. For example, 1002 may be performed by the SR configuration component 1240. For example, at 1004, the UE may receive a plurality of SR configurations including the SR configuration. For example, 1004 may be performed by the SR configuration component 1240. For example, referring to the aforementioned figures, the UE 902 may receive one or more SR configurations 908 from the base station 904.

[0135] At 1006, the UE may receive an SR resource configuration associated with the SR configuration. For example, 1006 may be performed by the SR resource configuration component 1242. For example, referring to the above figures, the UE 902 may receive the SR resource configuration 910 from the base station 904, which in some examples may correspond to Figure 7 SR resource configuration 702 in.

[0136] At 1008, the UE may receive a logical channel configuration associated with the SR configuration. For example, 1008 may be performed by a logical channel configuration component 1244. For example, referring to the aforementioned figures, the UE 902 may receive a logical channel configuration 914 from the base station 904. The logical channel configuration 914 may include or be associated with a BSR configuration.

[0137] At 1010, the UE may receive a message indicating an activity status of an SR configuration, wherein the activity status indicates whether the SR configuration is active or inactive. For example, 1010 may be performed by the message component 1246. For example, referring to Figure 7 and Fig. 9 , the UE 902 may receive a message 916 from the base station 904, which in some examples may correspond to the activate resource message 710 or 712. After the base station 904 configures the SR configuration 908 for the UE 902 via RRC configuration, the base station 904 may send a message 916 to the UE 902 via L1 or L2 signaling to activate or deactivate the SR configuration 908. For example, the message 916 may include a bit that activates or deactivates the SR configuration 908 for the logical channel depending on whether the bit is 0 or 1.

[0138] In one example, the message may indicate another activity state of the SR resource configuration received at 1006, and the other activity state may indicate whether the SR resource configuration is active or inactive. Figure 7 and Fig. 9 After the base station 904 configures the SR resource configuration 702, 910 for the UE 902 via RRC configuration, the base station 904 may send a message 916 to the UE 902 via L1 or L2 signaling to activate or deactivate the SR resource configuration 910. For example, the message 916 may include a bit that activates or deactivates the SR resource configuration 910 for the SR configuration 908 depending on whether the bit is 0 or 1.

[0139] In one example, the message may indicate the duration of the active state of the SR configuration. Fig. 9 , the message 916 may specify a duration for activating or deactivating SR transmission, which may be expressed in time units or in the number of SR opportunities. For example, the message 916 may indicate that the UE 902 may transmit the SR 926 or refrain from transmitting any SR within a certain time period or a given number of SR opportunities.

[0140] In one example, the SR configuration may be associated with an inhibit timer, the message may modify the timer state of the inhibit timer, and the timer state may indicate whether the inhibit timer is started, restarted, or stopped. Fig. 9, the base station 904 may configure at least the following parameters for the scheduling request process for each SR configuration 908: an inhibit timer, and a maximum number of SR transmissions. The message 916 may modify the inhibit timer associated with the SR configuration 908. For example, the message 916 may start, restart, or stop the inhibit timer associated with the SR configuration to control the timing of subsequent SR transmissions.

[0141] In one example, the logical channel configuration received at 1008 may indicate a transmission state of the SR, which may indicate whether the transmission of the SR is enabled, disabled, or delayed in response to available data for the logical channel, and the message may modify the transmission state of the logical channel configuration. Fig. 9 , the UE 902 may receive a logical channel configuration 914 associated with the SR configuration 908, the logical channel configuration including a logical channel SR mask, an SR delay timer application flag, and an SR delay timer, and a message 916 may modify the logical channel parameters associated with the SR configuration 908. For example, the message 916 may enable, disable, or delay the triggering of the SR 926 when data is available for the logical channel, for example, by switching the logical channel SR mask or the SR delay timer application flag, or by starting, restarting, or stopping the SR delay timer for the SR configuration.

[0142] In one example where multiple SR configurations are received (at 1004), the message may indicate the activity status of only the SR configuration (received at 1002) or other activity statuses for each of the multiple SR configurations. For example, in the aforementioned example, activation and deactivation may be specific to one SR configuration, or activation and deactivation may apply to multiple SR configurations. For example, Figure 7 As illustrated in the example of , base station 704 may transmit one message specifically activating or deactivating SR resource configuration 1, namely, activation resource message 710, and another message specifically activating or deactivating SR resource configuration 2, namely, activation resource message 712. However, in an alternative example, activation resource message 710 or 712 may activate or deactivate both SR resource configurations 1 and 2.

[0143] In one example, the message may be a unicast message to the UE, a multicast message to multiple UEs including the UE, or a broadcast message to a serving cell including the UE. For example, in the foregoing example, activation and deactivation may be specific to one UE, or activation and deactivation may be signaled by multicast or broadcast to a cell including multiple UEs. For example, as Figure 7 Alternatively to the example of , the deactivate resources message 714 may be broadcast to multiple UEs including UE 706, informing these UEs that the base station 704 will not monitor SR resource configuration 1 for SR transmissions from any associated UE (not just UE 706).

[0144] In one example, the SR configuration may be associated with multiple PUCCH resources for a BWP, and the SR configuration may be associated with a logical channel, SCell beam failure recovery, or continuous LBT failure recovery. Fig. 9 , the base station 904 may configure multiple PUCCH resources for SR 926 on a given BWP. For example, the base station 904 may allow the UE 902 to send SR in multiple PUCCH resources on the BWP in response to data availability of logical channels associated with SR 926, SCell beam failure recovery, or continuous LBT failure recovery. Therefore, even if the base station 904 deactivates one PUCCH resource for SR, SR 926 may have at least one other PUCCH resource available for UE 902 to apply.

[0145] In one example, the SR resource configuration received at 1006 may be associated with the SR configuration and configure parameters for the SR, and the message at 1010 may reconfigure parameters for the SR. Fig. 9 After the base station 904 configures the SR configuration 908 and the SR resource configuration 910 associated with the SR configuration 908 via RRC configuration, the base station 904 may dynamically modify the parameters of the SR resource configuration 910 using some other L1 / L2 signaling in the DCI, MAC-CE, or via the message 916. Such parameters may include, for example, the periodicity and offset of the SR opportunity indicated in the SR resource configuration 910.

[0146] In one example, the message may indicate the active time of the SR configuration, and the active time may indicate the active state of the SR configuration or when the reconfiguration takes effect. Fig. 9 , the base station 904 may provide DCI, MAC-CE or other L1 / L2 signaling via message 916, which notifies the UE 902 not only about the activation, deactivation or reconfiguration of the SR opportunity, but also about the time delay until the activation, deactivation or reconfiguration begins. Figure 7 As an alternative to the example, in addition to activating the SR opportunity 708 for SR resource configuration 1, the activation resource message 710 may also indicate that the activation will occur a number of symbols, time slots, subframes, SR opportunities, or other time units after the transmission of the activation resource message 710, thereby delaying the occurrence of the initial SR opportunity until that time unit has passed.

[0147] In one example, the message may activate, deactivate, or reconfigure the SR configuration based on the UE capabilities. Fig. 9, the UE 902 may indicate to the base station 904 in a capability information message 906 that the UE is capable of activating, deactivating, or reconfiguring the SR configuration 908, and the base station 904 may configure and send DCI, MAC-CE, or other L1 / L2 signaling via a message 916 from the base station 904 that activates, deactivates, or reconfigures the SR configuration 908 according to any of the foregoing examples in response to the indicated UE capabilities. For example, as Figure 7 Alternatively to the example of , the base station 704 may send an activate resources message 710 to the UE 706 to activate the SR opportunity 708 in the SR resource configuration 1 in response to the UE 706 previously indicating an ability to handle such messages from the base station.

[0148] At 1012, the UE may receive a DTX configuration associated with a UE transmit configuration and indicating an active time duration for UE transmissions associated with the UE transmit configuration. The UE transmit configuration may be, for example, an SR configuration received at 1002, and the UE transmission may be, for example, an SR associated with the SR configuration. Additionally or alternatively, the UE transmit configuration may be, for example, a CG-PUSCH configuration, a RACH configuration, or other uplink transmit configuration. The DTX configuration may also indicate resources used for UE transmissions. In one example, the UE may receive the UE transmit configuration associated with the UE transmission in the same message or a different message as the message including the DTX configuration. For example, 1012 may be performed by a DTX configuration component 1248. For example, referring to Fig. 9 , the UE 902 may receive a DTX configuration 918 from the base station 904, the DTX configuration indicating at least an on-duration during which the UE 902 may send an SR 926 and valid resources in which the UE 902 may send an SR 926. For example, referring to Figure 8 In response to receiving the DTX configuration 810, the UE 808 may transmit in valid resources (e.g., SR opportunities 802) that fall within the active intervals (e.g., on-duration 812) indicated in the DTX configuration 810, and suspend transmission outside these intervals.

[0149] In one example, the DTX configuration may indicate at least one of: a start time of a DTX cycle, an active time duration during a DTX cycle, an inactive time duration during a DTX cycle, a time delay before the start time of a DTX cycle, or a time duration or periodicity of a DTX cycle. Figure 8 and Fig. 9The DTX configuration 810, 918 provided by the base station 806, 904 to the UE 808, 902 may include at least one of the following parameters: the time when the DTX cycle 816 starts (start time), the on duration 812 (active time duration) during which the UE 808 can send uplink data on valid resources, the off duration 814 (inactive time duration) during which the resources for uplink transmission of the UE 808 are masked, the delay 818 (time delay) before starting the on duration 812 within the DTX cycle 816, and the duration or periodicity of the DTX cycle 816.

[0150] In one example, the DTX configuration may indicate multiple DTX cycles. Figure 8 and Fig. 9 , the DTX configurations 810, 918 may also include multiple DTX cycles, such as a long DTX cycle and a short DTX cycle. Figure 8 Alternatively to the example of , DTX configuration 810 may configure a long DTX cycle corresponding to DTX cycle 816 (having equal to Figure 8 816) and a short DTX cycle that is less than the long DTX cycle and activated in response to activity within the long DTX cycle's on duration 812. The short DTX cycle may last for a configured time duration, after which, if no activity occurs within the on duration, the DTX cycle may revert to the long DTX cycle.

[0151] In one example, the DTX configuration may be associated with or may be directed to at least one of: a SR transmission of the UE, a SR transmission associated with a SR configuration or a SR resource configuration of the UE, a CG-PUSCH transmission of the UE, a CG-PUSCH transmission associated with a CG configuration, a RACH transmission of the UE, or an uplink transmission of the UE. Fig. 9 , the DTX configuration 918 can be associated with one or more types of transmissions of the UE 902. In one example, referring to Figure 8 , the DTX configuration 810 may configure the UE 808 to send any SR for any SR configuration in any SR opportunity within the on duration 812 but not within the off duration 814. Figure 8 In an alternative embodiment of the example, the DTX configuration 810 may configure the UE to send an SR for at least one specific SR configuration or SR resource configuration (but not in other unspecified SR configurations or SR resource configurations of the UE) in the associated SR opportunities within the on duration 812 but not within the off duration 814. Figure 8, the DTX configuration 810 may configure the UE 808 to send uplink data in response to a configuration grant configured for any configuration grant in any CG-PUSCH opportunity within the on duration 812 but not within the off duration 814. Figure 8 Alternatively to the example of , DTX configuration 810 may configure UE 808 to send uplink data in response to a configuration grant for at least one specific configuration grant configuration (but not for other unspecified configuration grant configurations of the UE) in an associated CG-PUSCH opportunity within the on duration 812 but not within the off duration 814. In another example, as Figure 8 In an alternative embodiment of the example, the DTX configuration 810 may configure the UE 808 to send a RACH signal during the on duration 812 but not during the off duration 814. Figure 8 In an alternative to the example of , the DTX configuration 810 may configure the UE 808 to send any uplink data (e.g., PUCCH data or PUSCH data) during the on duration 812 but not during the off duration 814. In another example, the DTX configuration 810, 918 may be associated with a combination of any of the aforementioned transmissions (e.g., SR, CG-PUSCH, RACH, general UL, etc.).

[0152] In one example, the DTX configuration may be associated with an uplink transmission of the UE in a communication resource comprising at least one of: a BWP, one or more serving cells, a serving cell group, or a frequency range. Fig. 9 , the DTX configuration 918 can be associated with the communication resources used for uplink transmission of the UE 902. For example, as Figure 8 As an alternative to the example of , the DTX configuration 810 may configure the UE 808 to send SR, CG-PUSCH data, RACH signal, PUCCH data, PUSCH data, or other uplink data in at least one specific BWP (but not for other unspecified BWPs), in one or more specific service cells (but not for other unspecified service cells), in at least one specific service cell group (but not for other unspecified service cell groups), in at least one specific frequency range (but not for other unspecified frequency ranges), or a combination of any of the above during the on duration 812 but not during the off duration 814.

[0153] At 1014, the UE may receive another DTX configuration associated with uplink transmissions of the UE, wherein the another DTX configuration indicates another active time duration consistent with the active time duration indicated in the DTX configuration at 1012. For example, 1014 may be performed by DTX configuration component 1248. For example, referring to Fig. 9 , the UE 902 may receive a DTX configuration 920 that indicates at least an on duration during which the UE 902 may transmit an uplink transmission 930. In one example, the active time duration of the DTX configuration received at 1012 coincides with another active time duration of another DTX configuration received at 1014. For example, as Figure 8 As an alternative to the example, the base station 806 may configure multiple DTX configurations 810 for the UE 808, including one DTX configuration for the SR opportunity 802 and one DTX configuration for uplink transmission other than SR, so that the start duration 812 of the DTX cycle 816 in the corresponding DTX configurations is consistent.

[0154] At 1016, the UE can receive a UE DRX configuration. For example, 1016 can be performed by DRX configuration component 1250. For example, referring to Fig. 9 , the UE 902 may receive a DRX configuration 922 that indicates at least an on-duration during which the UE 902 may monitor and receive downlink data from the base station 904. In one example, the DRX configuration may indicate another active time duration, and the active time duration of the DRX configuration received at 1012 and the other active time duration of the UE DRX configuration may coincide. For example, as Figure 8 As an alternative to the example of , the base station 806 may also configure a UE DRX configuration for the UE 808 together with the DTX configuration 810, such that a start duration 812 of a DTX cycle 816 in the DTX configuration is consistent with a start duration of a DRX cycle in the DRX configuration.

[0155] In one example, the DTX configuration received at 1012 may indicate a time extension of an active time duration of a DTX cycle, and the time extension may be triggered in response to uplink or downlink activity during the active time duration. Fig. 9 , the base station 904 may configure the time extension of the on-duration of the DTX and DRX cycles depending on the network traffic mode. Figure 8 As an alternative to the example of , the base station 806 may configure the DTX configuration 810 to include a time extension parameter such as an inactivity timer that indicates how long the length of the on duration 812 at the UE is extended in response to the UE sending or receiving data during the on duration 812.

[0156] In one example, the DRX configuration received at 1016 may indicate a DRX active time duration, the DTX configuration received at 1012 may indicate a time extension of the active time duration of the DTX cycle, and the time extension may be triggered in response to uplink or downlink activity during the DRX active time duration. Fig. 9 , the UE 902 may receive a DRX configuration 922 that indicates at least an on-duration during which the UE 902 may monitor and receive downlink data from the base station 904. Figure 8 As an alternative to the example of , similar to the DTX configuration 810, the base station 806 can also configure the DRX configuration for the UE 808 with its own DRX on duration and off duration. In this case, the base station 806 can configure the DTX configuration 810 to include a time extension parameter such as an inactivity timer, which indicates how long the length of the on duration 812 of the DTX cycle 816 is extended at the UE in response to the UE transmitting or receiving data during the DRX on duration.

[0157] At 1018, the UE may receive a message associated with the DTX configuration. For example, 1018 may be performed by the message component 1246. For example, referring to Fig. 9 , UE 902 may receive message 924 from base station 904. Message 924 may activate or deactivate, reconfigure DTX configuration 918, indicate parameters of the DTX configuration, or otherwise be associated with the DTX configuration via L1 or L2 signaling.

[0158] In one example, the UE may receive a semi-static indication or a dynamic indication of a DTX activity state of a DTX configuration, wherein the DTX activity state indicates whether the DTX configuration is active or inactive for uplink transmissions of the device or UE. For example, the message received at 1018 may semi-statically or dynamically indicate a DTX activity state of a DTX configuration, wherein the DTX activity state indicates whether the DTX configuration is active or inactive. For example, referring to Fig. 9 , the base station 904 may activate or deactivate the DTX configuration 918 via a message 924. For example, as Figure 8In an alternative to the example of , the base station 806 may send an RRC configuration or other layer 3 message, or a DCI, MAC-CE, or other L1 or L2 message, thereby indicating to the UE 808 that the DTX configuration 810 is active, in response to which the UE and the base station may apply the DTX cycle 816 to general uplink transmissions. Thus, during the on duration of the DTX cycle 816 but not during the off duration of the DTX cycle 816, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general uplink transmissions in cell DRX. Later, the base station may send a similar message to the UE 808 indicating that the DTX configuration 810 is inactive, in response to which the UE and the base station may no longer apply the DTX cycle 816 to general uplink transmissions. Thus, during the OFF duration as well as the ON duration of the DTX cycle 816, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general uplink transmissions in cell DRX.

[0159] In one example, the UE may receive a semi-static indication or a dynamic indication of an activity status of a UE transmit configuration, wherein the activity status indicates whether the UE transmit configuration is active or inactive relative to the DTX configuration. For example, the message received at 1018, the message received at 1010, the DTX configuration, or the SR or CG-PUSCH or other UE transmit configuration may semi-statically or dynamically indicate the activity status of general SR transmissions, SR transmissions associated with a specific SR configuration or SR resource configuration, general CG-PUSCH transmissions, CG-PUSCH transmissions associated with a specific CG-PUSCH configuration (such as type 1 or type 2), RACH transmissions, or other UE transmissions generally or specifically to certain UE transmit configurations relative to DTX, wherein the activity status indicates whether the DTX configuration is active or inactive relative to these specific types of UE transmissions or specific UE transmit configurations.

[0160] For example, refer to Fig. 9 , the base station 904 may activate or deactivate the application of DTX to SR configuration, CG-PUSCH configuration or other UE transmission configuration via message 924, message 916 or other messages or configurations. Figure 8In an alternative to the example of , the base station 806 may send an RRC configuration or other layer 3 message, or a DCI, MAC-CE, or other L1 or L2 message, thereby indicating to the UE 808 that the DTX configuration 810 is active or inactive for general SR or CG-PUSCH transmissions or SR or CG-PUSCH transmissions configured per a specific SR or CG, and in response to the indication, the UE and the base station may apply or not specifically apply the DTX cycle 816 for these types of UE transmissions, respectively. Thus, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general SR transmissions, SR transmissions configured per SR, general CG-PUSCH transmissions, or CG-PUSCH transmissions configured per CG in cell DRX, and when these transmissions are active with respect to DTX, they have opportunities that overlap with the on duration of the DTX cycle 816 but do not overlap with the off duration or inactive period of the DTX cycle 816. Similarly, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general SR transmissions, SR transmissions per SR configuration, general CG-PUSCH transmissions, or CG-PUSCH transmissions per CG configuration in cell DRX, and when these transmissions are inactive relative to DTX, they have timing that overlaps with the off duration or inactive period of the DTX cycle 816 and with the on duration of the DTX cycle 816.

[0161] In one example, the UE may also receive a semi-static indication or a dynamic indication of another activity state of a different configuration associated with another UE transmission, wherein the other activity state indicates whether the different configuration is active or inactive relative to another DTX configuration received at 1014. For example, referring to Fig. 9 , the base station 904 may activate or deactivate the SR configuration, CG-PUSCH configuration, or other UE transmission configuration via message 924, message 916, or other messages or configurations for multiple DTX configurations 918, 920 with consistent DTX cycles, respectively. Figure 8 In an alternative embodiment of the example, the base station 806 may send multiple RRC configurations or other layer 3 messages, or multiple DCI, MAC-CE, or other L1 or L2 messages to indicate to the UE 808 that multiple DTX configurations 810 are active or inactive for general SR or CG-PUSCH transmissions or SR or CG-PUSCH transmissions configured according to specific SR or CG, respectively. In response to the indication, the UE and the base station may apply or not specifically apply a consistent DTX cycle for these types of UE transmissions, respectively.

[0162] In one example, the DTX configuration received at 1012 may further indicate a plurality of DTX cycles, and the message received at 1018 may interrupt or cancel an initial DTX cycle in the plurality of DTX cycles. Fig. 9 , the base station 904 may send a message 924 notifying the UE 902 to stop applying DTX during the on duration of the initial DTX cycle. Figure 8 As an alternative to the example of , the base station 806 may send a DCI, MAC-CE, or other L1 or L2 message to indicate to the UE 808 that at least a portion of the turn-on duration 812 is not to be applied during the initially configured DTX cycle and therefore no uplink data is to be sent during that portion or duration until the next DTX cycle.

[0163] In one example, the DTX configuration received at 1012 may include parameters for the UE to transmit, and the message received at 1018 may reconfigure the parameters. Fig. 9 , the base station 904 may send a message 924 that modifies at least one of the DTX start offset, on duration, off duration, delay, periodicity, or other parameters of the DTX configuration 918. Figure 8 Alternatively to the example of , base station 806 may send a DCI, MAC-CE, or other L1 or L2 message that reconfigures delay 818 to be longer or shorter than illustrated, reconfigures on duration 812 or off duration 814 to be longer or shorter than illustrated, reconfigures to have a different periodicity of DTX cycle 816, or reconfigures to include some other reconfiguration.

[0164] In one example, the message received at 1018 may activate, deactivate, or reconfigure the DTX configuration received at 1012 based on UE capabilities. Fig. 9 In response to identifying from the capability information message 906 that the UE 902 is capable of applying DTX, the base station 904 may provide the UE 902 with a DTX configuration 918, followed by a message 924 associated with the DTX configuration 918. For example, as Figure 8In an alternative to the example of , the UE 808 may initially send a capability information message to the base station 806, the capability information message indicating that the UE is capable of supporting general DTX, DTX for general SR configuration or for specific SR configuration, DTX for general configuration grant configuration or for specific configuration grant configuration, DTX for RACH signals, DTX for general uplink signals, DTX for specific BWP, DTX for specific serving cells, DTX for specific serving cell groups, DTX for specific frequency ranges, etc. through one or more UE capabilities. In response to receiving the capability information message and determining that the UE is capable of, for example, general DTX, the base station 806 may configure the DTX configuration 810 and provide the DTX configuration accordingly to the UE 808. In addition, the base station 806 may provide a DCI, MAC-CE, or other L1 or L2 signaling that activates, deactivates, or reconfigures the DTX configuration 810 according to any of the foregoing examples.

[0165] In one example, the message received at 1018 may indicate parameters associated with the DTX configuration received at 1012, wherein the message is a SIB or multicast message for multiple UEs including the UE. Fig. 9 , the base station 904 may indicate at least one of the DTX start offset, on duration, off duration, delay, periodicity, or other parameters of the DTX configuration 918 in a SIB broadcast to UEs (including UE 902) in the serving cell or in a multicast or groupcast message to certain UEs (including UE 902). Here, the SIB or multicast / groupcast message may correspond to the message 924. Therefore, as Figure 8 Alternatively to the example of , the base station 806 may initially notify the UE 808 of at least one parameter of the DTX configuration 810, such as the delay 818, the on duration 812, or the off duration 814, via a SIB or multicast message to the UE 808 and other UEs.

[0166] Finally, at 1020, the UE may transmit during the active time duration indicated in the DTX configuration. For example, 1020 may be performed by uplink component 1252. For example, referring to Fig. 9 In response to message 916 indicating that these configurations are currently active, UE 902 may send SR 926 in resources configured by SR configuration 908 and SR resource configuration 910, or send CG-PUSCH 928 or uplink transmission 930 in resources configured by the associated CG or other configuration, respectively. In one example, the SR, CG-PUSCH or other UL transmission sent at 1020 may be sent in resources of a DTX configuration received at 1012 during the active time duration of the DTX configuration. For example, referring to Fig. 9, UE 902 may send SR 926, CG-PUSCH 928 or uplink transmission 930 in the resources configured in DTX configuration 918 during the DTX on duration configured in DTX configuration 918.

[0167] Fig.11 1100 is a flow chart of a method of wireless communication. The method may be performed by a network entity such as a base station (e.g., base station 102 / 180, 310, 504, 604, 654, 704, 806, 904; device 1302). Optional aspects are illustrated by dashed lines. The method allows a base station or other network entity to receive an SR or other uplink transmission from a UE in UE DTX or cell DRX in response to a message indicating dynamic activation, deactivation, or reconfiguration of a DTX configuration, an SR configuration, or other uplink transmission configuration, so as to provide energy savings at the base station.

[0168] At 1102, the network entity can send an SR configuration associated with the SR. For example, 1102 can be performed by the SR configuration component 1340. For example, at 1104, the base station can send a plurality of SR configurations including the SR configuration. For example, 1104 can be performed by the SR configuration component 1340. For example, referring to the aforementioned figures, the UE 902 can receive one or more SR configurations 908 from the base station 904.

[0169] At 1106, the network entity may send an SR resource configuration associated with the SR configuration. For example, 1106 may be performed by SR resource configuration component 1342. For example, referring to the above figures, UE 902 may receive SR resource configuration 910 from base station 904, which in some examples may correspond to Figure 7 SR resource configuration 702 in.

[0170] At 1108, the network entity may send a logical channel configuration associated with the SR configuration. For example, 1108 may be performed by a logical channel configuration component 1344. For example, referring to the aforementioned figures, the UE 902 may receive a logical channel configuration 914 from the base station 904. The logical channel configuration 914 may include or be associated with a BSR configuration.

[0171] At 1110, the network entity can send a message indicating an activity status of the SR configuration, wherein the activity status indicates whether the SR configuration is active or inactive. For example, 1110 can be performed by the message component 1346. For example, referring to Figure 7 and Fig. 9, the UE 902 may receive a message 916 from the base station 904, which in some examples may correspond to the activate resource message 710 or 712. After the base station 904 configures the SR configuration 908 for the UE 902 via RRC configuration, the base station 904 may send a message 916 to the UE 902 via L1 or L2 signaling to activate or deactivate the SR configuration 908. For example, the message 916 may include a bit that activates or deactivates the SR configuration 908 for the logical channel depending on whether the bit is 0 or 1.

[0172] In one example, the message may indicate another activity state of the SR resource configuration sent at 1106, and the other activity state may indicate whether the SR resource configuration is active or inactive. Figure 7 and Fig. 9 After the base station 904 configures the SR resource configuration 702, 910 for the UE 902 via RRC configuration, the base station 904 may send a message 916 to the UE 902 via L1 or L2 signaling to activate or deactivate the SR resource configuration 910. For example, the message 916 may include a bit that activates or deactivates the SR resource configuration 910 for the SR configuration 908 depending on whether the bit is 0 or 1.

[0173] In one example, the message may indicate the duration of the active state of the SR configuration. Fig. 9 , the message 916 may specify a duration for activating or deactivating SR transmission, which may be expressed in time units or in the number of SR opportunities. For example, the message 916 may indicate that the UE 902 may transmit the SR 926 or refrain from transmitting any SR within a certain time period or a given number of SR opportunities.

[0174] In one example, the SR configuration may be associated with an inhibit timer, the message may modify the timer state of the inhibit timer, and the timer state may indicate whether the inhibit timer is started, restarted, or stopped. Fig. 9 , the base station 904 may configure at least the following parameters for the scheduling request process for each SR configuration 908: an inhibit timer, and a maximum number of SR transmissions. The message 916 may modify the inhibit timer associated with the SR configuration 908. For example, the message 916 may start, restart, or stop the inhibit timer associated with the SR configuration to control the timing of subsequent SR transmissions.

[0175] In one example, the logical channel configuration sent at 1108 may indicate a transmission state of the SR, which may indicate whether the transmission of the SR is enabled, disabled, or delayed in response to available data for the logical channel, and the message may modify the transmission state of the logical channel configuration. Fig. 9, the UE 902 may receive a logical channel configuration 914 associated with the SR configuration 908, the logical channel configuration including a logical channel SR mask, an SR delay timer application flag, and an SR delay timer, and a message 916 may modify the logical channel parameters associated with the SR configuration 908. For example, the message 916 may enable, disable, or delay the triggering of the SR 926 when data is available for the logical channel, for example, by switching the logical channel SR mask or the SR delay timer application flag, or by starting, restarting, or stopping the SR delay timer for the SR configuration.

[0176] In one example where multiple SR configurations are sent (at 1104), the message may indicate the activity status of only the SR configuration (sent at 1102) or other activity statuses for each of the multiple SR configurations. For example, in the aforementioned example, activation and deactivation may be specific to one SR configuration, or activation and deactivation may apply to multiple SR configurations. For example, Figure 7 As illustrated in the example of , base station 704 may transmit one message specifically activating or deactivating SR resource configuration 1, namely, activation resource message 710, and another message specifically activating or deactivating SR resource configuration 2, namely, activation resource message 712. However, in an alternative example, activation resource message 710 or 712 may activate or deactivate both SR resource configurations 1 and 2.

[0177] In one example, the message may be a unicast message to the UE, a multicast message to multiple UEs including the UE, or a broadcast message to a serving cell including the UE. For example, in the foregoing example, activation and deactivation may be specific to one UE, or activation and deactivation may be signaled by multicast or broadcast to a cell including multiple UEs. For example, as Figure 7 Alternatively to the example of , the deactivate resources message 714 may be broadcast to multiple UEs including UE 706, informing these UEs that the base station 704 will not monitor SR resource configuration 1 for SR transmissions from any associated UE (not just UE 706).

[0178] In one example, the SR configuration may be associated with multiple PUCCH resources for a BWP, and the SR configuration may be associated with a logical channel, SCell beam failure recovery, or continuous LBT failure recovery. Fig. 9, the base station 904 may configure multiple PUCCH resources for SR 926 on a given BWP. For example, the base station 904 may allow the UE 902 to send SR in multiple PUCCH resources on the BWP in response to data availability of logical channels associated with SR 926, SCell beam failure recovery, or continuous LBT failure recovery. Therefore, even if the base station 904 deactivates one PUCCH resource for SR, SR 926 may have at least one other PUCCH resource available for UE 902 to apply.

[0179] In one example, the SR resource configuration sent at 1106 may be associated with the SR configuration and configure parameters for the SR, and the message at 1110 may reconfigure the parameters for the SR. Fig. 9 After the base station 904 configures the SR configuration 908 and the SR resource configuration 910 associated with the SR configuration 908 via RRC configuration, the base station 904 may dynamically modify the parameters of the SR resource configuration 910 using some other L1 / L2 signaling in the DCI, MAC-CE, or via the message 916. Such parameters may include, for example, the periodicity and offset of the SR opportunity indicated in the SR resource configuration 910.

[0180] In one example, the message may indicate the active time of the SR configuration, and the active time may indicate the active state of the SR configuration or when the reconfiguration takes effect. Fig. 9 , the base station 904 may provide DCI, MAC-CE or other L1 / L2 signaling via message 916, which notifies the UE 902 not only about the activation, deactivation or reconfiguration of the SR opportunity, but also about the time delay until the activation, deactivation or reconfiguration begins. Figure 7 As an alternative to the example, in addition to activating the SR opportunity 708 for SR resource configuration 1, the activation resource message 710 may also indicate that the activation will occur a number of symbols, time slots, subframes, SR opportunities, or other time units after the transmission of the activation resource message 710, thereby delaying the occurrence of the initial SR opportunity until that time unit has passed.

[0181] In one example, the message may activate, deactivate, or reconfigure the SR configuration based on the UE capabilities. Fig. 9 , the UE 902 may indicate to the base station 904 in a capability information message 906 that the UE is capable of activating, deactivating, or reconfiguring the SR configuration 908, and the base station 904 may configure and send DCI, MAC-CE, or other L1 / L2 signaling via a message 916 from the base station 904 that activates, deactivates, or reconfigures the SR configuration 908 according to any of the foregoing examples in response to the indicated UE capabilities. For example, as Figure 7Alternatively to the example of , the base station 704 may send an activate resources message 710 to the UE 706 to activate the SR opportunity 708 in the SR resource configuration 1 in response to the UE 706 previously indicating an ability to handle such messages from the base station.

[0182] At 1112, the network entity may send a DTX configuration associated with a UE transmit configuration and indicating an active time duration for UE transmissions associated with the UE transmit configuration. The UE transmit configuration may be, for example, an SR configuration sent at 1002, and the UE transmission may be, for example, an SR associated with the SR configuration. Additionally or alternatively, the UE transmit configuration may be, for example, a CG-PUSCH configuration, a RACH configuration, or other uplink transmit configuration. The DTX configuration may also indicate resources used for UE transmissions. In one example, the network entity may send the UE transmit configuration associated with the UE transmission in the same message or a different message as the message including the DTX configuration. For example, 1112 may be performed by the DTX configuration component 1348. For example, referring to Fig. 9 , the UE 902 may receive a DTX configuration 918 from the base station 904, the DTX configuration indicating at least an on-duration during which the UE 902 may send an SR 926 and valid resources in which the UE 902 may send an SR 926. For example, referring to Figure 8 In response to receiving the DTX configuration 810, the UE 808 may transmit in valid resources (eg, SR opportunities 802) that fall within the active intervals (eg, on-duration 812) indicated in the DTX configuration 810, and suspend transmission outside of these intervals.

[0183] In one example, the DTX configuration may indicate at least one of: a start time of a DTX cycle, an active time duration during a DTX cycle, an inactive time duration during a DTX cycle, a time delay before the start time of a DTX cycle, or a time duration or periodicity of a DTX cycle. Figure 8 and Fig. 9 The DTX configuration 810, 918 provided by the base station 806, 904 to the UE 808, 902 may include at least one of the following parameters: the time when the DTX cycle 816 starts (start time), the on duration 812 (active time duration) during which the UE 808 can send uplink data on valid resources, the off duration 814 (inactive time duration) during which the resources for uplink transmission of the UE 808 are masked, the delay 818 (time delay) before starting the on duration 812 within the DTX cycle 816, and the duration or periodicity of the DTX cycle 816.

[0184] In one example, the DTX configuration may indicate multiple DTX cycles. Figure 8and Fig. 9 , the DTX configurations 810, 918 may also include multiple DTX cycles, such as a long DTX cycle and a short DTX cycle. Figure 8 Alternatively to the example of , DTX configuration 810 may configure a long DTX cycle corresponding to DTX cycle 816 (having equal to Figure 8 816) and a short DTX cycle that is less than the long DTX cycle and activated in response to activity within the long DTX cycle's on duration 812. The short DTX cycle may last for a configured time duration, after which, if no activity occurs within the on duration, the DTX cycle may revert to the long DTX cycle.

[0185] In one example, the DTX configuration may be associated with or may be directed to at least one of: a SR transmission of the UE, a SR transmission associated with a SR configuration or a SR resource configuration of the UE, a CG-PUSCH transmission of the UE, a CG-PUSCH transmission associated with a CG configuration, a RACH transmission of the UE, or an uplink transmission of the UE. Fig. 9 , the DTX configuration 918 can be associated with one or more types of transmissions of the UE 902. In one example, referring to Figure 8 , the DTX configuration 810 may configure the UE 808 to send any SR for any SR configuration in any SR opportunity within the on duration 812 but not within the off duration 814. Figure 8 In an alternative embodiment of the example, the DTX configuration 810 may configure the UE to send an SR for at least one specific SR configuration or SR resource configuration (but not in other unspecified SR configurations or SR resource configurations of the UE) in the associated SR opportunities within the on duration 812 but not within the off duration 814. Figure 8 , the DTX configuration 810 may configure the UE 808 to send uplink data in response to a configuration grant configured for any configuration grant in any CG-PUSCH opportunity within the on duration 812 but not within the off duration 814. Figure 8 Alternatively to the example of , DTX configuration 810 may configure UE 808 to send uplink data in response to a configuration grant for at least one specific configuration grant configuration (but not for other unspecified configuration grant configurations of the UE) in an associated CG-PUSCH opportunity within the on duration 812 but not within the off duration 814. In another example, as Figure 8 In an alternative embodiment of the example, the DTX configuration 810 may configure the UE 808 to send a RACH signal during the on duration 812 but not during the off duration 814. Figure 8 In an alternative to the example of , the DTX configuration 810 may configure the UE 808 to send any uplink data (e.g., PUCCH data or PUSCH data) during the on duration 812 but not during the off duration 814. In another example, the DTX configuration 810, 918 may be associated with a combination of any of the aforementioned transmissions (e.g., SR, CG-PUSCH, RACH, general UL, etc.).

[0186] In one example, the DTX configuration may be associated with an uplink transmission of the UE in a communication resource comprising at least one of: a BWP, one or more serving cells, a serving cell group, or a frequency range. Fig. 9 , the DTX configuration 918 can be associated with the communication resources used for uplink transmission of the UE 902. For example, as Figure 8 As an alternative to the example of , the DTX configuration 810 may configure the UE 808 to send SR, CG-PUSCH data, RACH signal, PUCCH data, PUSCH data, or other uplink data in at least one specific BWP (but not for other unspecified BWPs), in one or more specific service cells (but not for other unspecified service cells), in at least one specific service cell group (but not for other unspecified service cell groups), in at least one specific frequency range (but not for other unspecified frequency ranges), or a combination of any of the above during the on duration 812 but not during the off duration 814.

[0187] At 1114, the network entity may send another DTX configuration associated with the uplink transmission of the UE, wherein the another DTX configuration indicates another active time duration consistent with the active time duration indicated in the DTX configuration at 1112. For example, 1114 may be performed by DTX configuration component 1348. For example, referring to Fig. 9 , the UE 902 may receive a DTX configuration 920 that indicates at least an on duration during which the UE 902 may transmit an uplink transmission 930. In one example, the active time duration of the DTX configuration received at 1012 coincides with another active time duration of another DTX configuration received at 1014. For example, as Figure 8 As an alternative to the example, the base station 806 may configure multiple DTX configurations 810 for the UE 808, including one DTX configuration for the SR opportunity 802 and one DTX configuration for uplink transmission other than SR, so that the start duration 812 of the DTX cycle 816 in the corresponding DTX configurations is consistent.

[0188] At 1116, the network entity can send the UE DRX configuration. For example, 1116 can be performed by DRX configuration component 1350. For example, referring to Fig. 9 , UE 902 may receive DRX configuration 922, which indicates at least an on-duration during which UE 902 may monitor and receive downlink data from base station 904. In one example, the DRX configuration may indicate another active time duration, and the active time duration of the DTX configuration received at 1012 and the other active time duration of the DRX configuration may coincide. For example, as Figure 8 As an alternative to the example of , the base station 806 may also configure a UE DRX configuration for the UE 808 together with the DTX configuration 810, such that a start duration 812 of a DTX cycle 816 in the DTX configuration is consistent with a start duration of a DRX cycle in the DRX configuration.

[0189] In one example, the DTX configuration sent at 1112 may indicate a time extension of an active time duration of a DTX cycle, and the time extension may be triggered in response to uplink or downlink activity during the active time duration. Fig. 9 , the base station 904 may configure the time extension of the on-duration of the DTX and DRX cycles depending on the network traffic mode. Figure 8 As an alternative to the example of , the base station 806 may configure the DTX configuration 810 to include a time extension parameter such as an inactivity timer that indicates how long the length of the on duration 812 at the UE is extended in response to the UE sending or receiving data during the on duration 812.

[0190] In one example, the DRX configuration sent at 1116 may indicate a DRX active time duration, the DTX configuration sent at 1112 may indicate a time extension of the active time duration of the DTX cycle, and the time extension may be triggered in response to uplink or downlink activity during the DRX active time duration. Fig. 9 , the UE 902 may receive a DRX configuration 922 that indicates at least an on-duration during which the UE 902 may monitor and receive downlink data from the base station 904. Figure 8 As an alternative to the example of , similar to the DTX configuration 810, the base station 806 can also configure the DRX configuration for the UE 808 with its own DRX on duration and off duration. In this case, the base station 806 can configure the DTX configuration 810 to include a time extension parameter such as an inactivity timer, which indicates how long the length of the on duration 812 of the DTX cycle 816 is extended at the UE in response to the UE transmitting or receiving data during the DRX on duration.

[0191] At 1118, the network entity can send a message associated with the DTX configuration. For example, 1118 can be performed by the message component 1346. For example, referring to Fig. 9 , UE 902 may receive message 924 from base station 904. Message 924 may activate or deactivate, reconfigure DTX configuration 918, indicate parameters of the DTX configuration, or otherwise be associated with the DTX configuration via L1 or L2 signaling.

[0192] In one example, the network entity may send a semi-static indication or a dynamic indication of a DTX activity state of a DTX configuration, wherein the DTX activity state indicates whether the DTX configuration is active or inactive for uplink transmissions of the UE. For example, the message sent at 1118 may semi-statically or dynamically indicate a DTX activity state of a DTX configuration, wherein the DTX activity state indicates whether the DTX configuration is active or inactive. For example, referring to Fig. 9 , the base station 904 may activate or deactivate the DTX configuration 918 via a message 924. For example, as Figure 8 In an alternative to the example of , the base station 806 may send an RRC configuration or other layer 3 message, or a DCI, MAC-CE, or other L1 or L2 message, thereby indicating to the UE 808 that the DTX configuration 810 is active, in response to which the UE and the base station may apply the DTX cycle 816 to general uplink transmissions. Thus, during the on duration of the DTX cycle 816 but not during the off duration of the DTX cycle 816, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general uplink transmissions in cell DRX. Later, the base station may send a similar message to the UE 808 indicating that the DTX configuration 810 is inactive, in response to which the UE and the base station may no longer apply the DTX cycle 816 to general uplink transmissions. Thus, during the OFF duration as well as the ON duration of the DTX cycle 816, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general uplink transmissions in cell DRX.

[0193] In one example, the network entity may send a semi-static indication or a dynamic indication of an activity status of a UE transmit configuration, wherein the activity status indicates whether the UE transmit configuration is active or inactive relative to the DTX configuration. For example, the message sent at 1118, the message sent at 1110, the DTX configuration, or the SR or CG-PUSCH or other UE transmit configuration may semi-statically or dynamically indicate the activity status of general SR transmissions, SR transmissions associated with a specific SR configuration or SR resource configuration, general CG-PUSCH transmissions, CG-PUSCH transmissions associated with a specific CG-PUSCH configuration (such as type 1 or type 2), RACH transmissions, or other UE transmissions generally or specifically for certain UE transmit configurations relative to DTX, wherein the activity status indicates whether the DTX configuration is active or inactive relative to these specific types of UE transmissions or specific UE transmit configurations.

[0194] For example, refer to Fig. 9 , the base station 904 may activate or deactivate the application of DTX to SR configuration, CG-PUSCH configuration or other UE transmission configuration via message 924, message 916 or other messages or configurations. Figure 8 In an alternative to the example of , the base station 806 may send an RRC configuration or other layer 3 message, or a DCI, MAC-CE, or other L1 or L2 message, thereby indicating to the UE 808 that the DTX configuration 810 is active or inactive for general SR or CG-PUSCH transmissions or SR or CG-PUSCH transmissions configured per a specific SR or CG, and in response to the indication, the UE and the base station may apply or not specifically apply the DTX cycle 816 for these types of UE transmissions, respectively. Thus, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general SR transmissions, SR transmissions configured per SR, general CG-PUSCH transmissions, or CG-PUSCH transmissions configured per CG in cell DRX, and when these transmissions are active with respect to DTX, they have opportunities that overlap with the on duration of the DTX cycle 816 but do not overlap with the off duration or inactive period of the DTX cycle 816. Similarly, the UE may be semi-statically or dynamically configured to transmit in UE DTX, or the base station may be semi-statically or dynamically configured to receive general SR transmissions, SR transmissions per SR configuration, general CG-PUSCH transmissions, or CG-PUSCH transmissions per CG configuration in cell DRX, and when these transmissions are inactive relative to DTX, they have timing that overlaps with the off duration or inactive period of the DTX cycle 816 and with the on duration of the DTX cycle 816.

[0195] In one example, the network entity may also send a semi-static indication or a dynamic indication of another activity state of a different configuration associated with another UE transmission, wherein the other activity state indicates whether the different configuration is active or inactive relative to another DTX configuration received at 1014. For example, referring to Fig. 9 , the base station 904 may activate or deactivate the SR configuration, CG-PUSCH configuration, or other UE transmission configuration via message 924, message 916, or other messages or configurations for multiple DTX configurations 918, 920 with consistent DTX cycles, respectively. Figure 8 In an alternative embodiment of the example, the base station 806 may send multiple RRC configurations or other layer 3 messages, or multiple DCI, MAC-CE, or other L1 or L2 messages to indicate to the UE 808 that multiple DTX configurations 810 are active or inactive for general SR or CG-PUSCH transmissions or SR or CG-PUSCH transmissions configured according to specific SR or CG, respectively. In response to the indication, the UE and the base station may apply or not specifically apply a consistent DTX cycle for these types of UE transmissions, respectively.

[0196] In one example, the DTX configuration sent at 1112 may further indicate a plurality of DTX cycles, and the message sent at 1118 may interrupt or cancel an initial DTX cycle in the plurality of DTX cycles. Fig. 9 , the base station 904 may send a message 924 notifying the UE 902 to stop applying DTX during the on duration of the initial DTX cycle. Figure 8 As an alternative to the example of , the base station 806 may send a DCI, MAC-CE, or other L1 or L2 message to indicate to the UE 808 that at least a portion of the turn-on duration 812 is not to be applied during the initially configured DTX cycle and therefore no uplink data is to be sent during that portion or duration until the next DTX cycle.

[0197] In one example, the DTX configuration sent at 1112 may include parameters for the UE to transmit, and the message sent at 1118 may reconfigure the parameters. Fig. 9 , the base station 904 may send a message 924 that modifies at least one of the DTX start offset, on duration, off duration, delay, periodicity, or other parameters of the DTX configuration 918. Figure 8 Alternatively to the example of , base station 806 may send a DCI, MAC-CE, or other L1 or L2 message that reconfigures delay 818 to be longer or shorter than illustrated, reconfigures on duration 812 or off duration 814 to be longer or shorter than illustrated, reconfigures to have a different periodicity of DTX cycle 816, or reconfigures to include some other reconfiguration.

[0198] In one example, the message sent at 1118 may activate, deactivate, or reconfigure the DTX configuration received at 1012 based on UE capabilities. Fig. 9 In response to identifying from the capability information message 906 that the UE 902 is capable of applying DTX, the base station 904 may provide the UE 902 with a DTX configuration 918, followed by a message 924 associated with the DTX configuration 918. For example, as Figure 8 In an alternative to the example of , the UE 808 may initially send a capability information message to the base station 806, the capability information message indicating that the UE is capable of supporting general DTX, DTX for general SR configuration or for specific SR configuration, DTX for general configuration grant configuration or for specific configuration grant configuration, DTX for RACH signals, DTX for general uplink signals, DTX for specific BWP, DTX for specific serving cells, DTX for specific serving cell groups, DTX for specific frequency ranges, etc. through one or more UE capabilities. In response to receiving the capability information message and determining that the UE is capable of, for example, general DTX, the base station 806 may configure the DTX configuration 810 and provide the DTX configuration accordingly to the UE 808. In addition, the base station 806 may provide a DCI, MAC-CE, or other L1 or L2 signaling that activates, deactivates, or reconfigures the DTX configuration 810 according to any of the foregoing examples.

[0199] In one example, the message sent at 1118 may indicate parameters associated with the DTX configuration received at 1012, wherein the message is a SIB or multicast message for multiple UEs including the UE. Fig. 9 , the base station 904 may indicate at least one of the DTX start offset, on duration, off duration, delay, periodicity, or other parameters of the DTX configuration 918 in a SIB broadcast to UEs (including UE 902) in the serving cell or in a multicast or groupcast message to certain UEs (including UE 902). Here, the SIB or multicast / groupcast message may correspond to the message 924. Therefore, as Figure 8 Alternatively to the example of , the base station 806 may initially notify the UE 808 of at least one parameter of the DTX configuration 810, such as the delay 818, the on duration 812, or the off duration 814, via a SIB or multicast message to the UE 808 and other UEs.

[0200] Finally, at 1120, the network entity can receive the UE transmission during the active time duration indicated in the DTX configuration. For example, 1120 can be performed by uplink component 1352. For example, referring to Fig. 9In response to message 916 indicating that these configurations are currently active, UE 902 may send SR 926 in resources configured by SR configuration 908 and SR resource configuration 910, or send CG-PUSCH 928 or uplink transmission 930 in resources configured by the associated CG or other configuration, respectively. In one example, the SR, CG-PUSCH or other UL transmission received at 1120 may be received in resources of the DTX configuration sent at 1112 during the active time duration of the DTX configuration. For example, referring to Fig. 9 , UE 902 may send SR 926, CG-PUSCH 928 or uplink transmission 930 in the resources configured in DTX configuration 918 during the DTX on duration configured in DTX configuration 918.
