Description

Background Art

[0001] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for discontinuous reception.

[0002] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0003] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. The UE may communicate with the network nodes via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).

[0004] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectrum efficiency; reducing costs; improving services; utilizing new spectrum; and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards; and supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0031] In some aspects, a user equipment (UE) may communicate according to a discontinuous reception (DRX) configuration. A DRX configuration may be associated with a DRX cycle. A DRX cycle may include a DRX on duration (e.g., during which the UE is awake or active) and an opportunity to enter a DRX sleep state. As used herein, the time during which the UE is configured to be active includes the DRX on duration and may be referred to as a DRX active time, and the time during which the UE is configured to be in a DRX sleep state may be referred to as an inactive time. The UE may monitor a physical downlink control channel (PDCCH) during the DRX active time, and may suppress monitoring of the PDCCH during the inactive time. For example, the UE may monitor the PDCCH for downlink control information (DCI) associated with the UE. If the UE does not detect and / or successfully decode any PDCCH communication intended for the UE during the DRX on duration, the UE may enter a sleep state (e.g., in an inactive time) at the end of the DRX on duration. In this way, the UE may save battery power and reduce power consumption. The DRX cycle may be repeated at a configured periodicity according to the DRX configuration.

[0032] If the UE detects and / or successfully decodes a PDCCH communication intended for the UE, the UE may remain in an active state (e.g., awake) for the duration of a DRX inactivity timer (IAT) (e.g., this may extend the DRX active time). The duration of the DRX IAT may be referred to as a DRX IAT duration. The DRX IAT duration may include a DRX HARQ retransmission timer and / or a DRX retransmission timer. During the DRX IAT duration, the UE may remain in an active state to monitor for retransmissions.

[0033] In some cases, some communications may be received in a semi-persistent manner. A semi-persistent communication configuration is a configuration associated with a semi-persistent communication. A semi-persistent communication is a communication configured so that more than one configured communication may occur without activating and / or dynamically scheduling each communication. For example, in a semi-persistent communication, two or more semi-persistent communication opportunities may be configured so that once the semi-persistent communication configuration is activated, communication may occur during each of the two or more semi-persistent communications. In some aspects, a semi-persistent communication configuration may include a semi-persistent scheduling (SPS) configuration and a configured grant (CG) configuration.

[0034] An example of semi-persistent communication is extended reality (XR) communication. "XR" is a term referring to a combined real and virtual environment and human-computer interaction generated by computer technology and wearable devices. For example, an XR environment can be used to implement a metaverse scene or network. Incomplete examples of XR include augmented reality, mixed reality, and virtual reality. XR may involve a certain amount of network communication. XR communication is a transmission or a series of transmissions (e.g., a service flow) associated with an XR application, such as a service flow carrying XR data. XR applications can be implemented on network nodes such as XR devices and / or UEs. XR devices may include, for example, XR headsets, laptops, personal computers, game consoles, and / or UEs. In some specific implementations, a certain amount of processing may be performed at the server, such as to generate a scene (e.g., a frame) that is communicated to the XR device via a service burst. A service burst may include one or more packets and may be associated with a scene (e.g., a frame) of an XR application. For example, a service burst may carry data associated with a scene (e.g., a frame). As another example, a network node may access remotely stored data for use in an XR environment. In some cases, XR communications may be associated with multiple service flows, such as a video service flow, an audio service flow, and a haptic service flow.

[0035] Some periodic communications such as XR communications may be inherently variable. For example, XR communications may be associated with variability in the number of packets per service burst and the size of each packet. XR communications may also be associated with non-integer periods. As another example, the arrival time of XR services may vary due to jitter and may not correspond to the expected arrival time. Jitter is the variation or uncertainty in the arrival time of a communication, such as the expected or observed deviation of the actual arrival time of a packet from the scheduled arrival time of the packet. As yet another example, multiple service flows of an XR communication may have variable parameters and characteristics, such as different data rates, different latency or reliability requirements, different packet sizes, and the like.

[0036] In some cases, a constrained packet delay budget (PDB) may be established for XR video frames (e.g., for AR / VR, the delay budget from the time a video frame arrives at a network node to the time the video frame is successfully transmitted to a UE may be 10ms). Using some dynamic signaling (e.g., wake-up signals and / or scheduling DCI, etc.) to indicate the data arrival time and the number of time slots of the physical data communication channel used to send the data may better accommodate jitter and variable frame sizes.

[0037] Early burst arrival of XR data at a network node (e.g., XR data arrives near the first end of a jitter distribution) may result in increased delay at a buffer (e.g., a downlink buffer) relative to an on-time burst arrival because scheduling a physical data communication channel for sending data associated with the burst may occur near the expected arrival time, close to the center of the jitter distribution. In some cases, early burst arrival may occur outside the DRX on duration, which may result in delayed reception of the XR data. Late burst arrival (which may occur outside the DRX on duration) may result in latency within the PDB and inefficient consumption of power resources prior to arrival. A DRX retransmission timer may be started after a burst arrives at the UE. Once the DRX retransmission timer is started, the UE monitors the PDCCH based on the HARQ process according to the configuration, even if the network does not intend to schedule retransmissions, which may result in unnecessary power consumption by the UE. With deadline-aware scheduling, some HARQ retransmissions may not be scheduled before the burst deadline, which may also result in unnecessary power consumption by the UE.

[0038] Some of the techniques described herein provide early termination of HARQ retransmission operations associated with DRX based on receiving a DCI containing a DFI, which is configured for downlink and / or uplink early HARQ termination for the purpose of saving power in scenarios involving variable communication time such as XR communications. For example, in some aspects, the UE may receive a DCI including a DFI field indicating a DFI value. The UE may terminate the HARQ retransmission operation based on receiving the DCI. The UE may transition from a first state to a second state based on terminating the HARQ retransmission operation, wherein the second state is a power saving state. In some aspects, the UE may terminate the HARQ retransmission operation by terminating the HARQ retransmission timer and / or by refreshing the HARQ buffer corresponding to the HARQ retransmission operation. In this way, some aspects described herein may facilitate termination of the HARQ retransmission operation before the end of the DRX active time, thereby improving resource allocation efficiency and reducing the power consumption of the UE. Therefore, some aspects may facilitate XR-specific power saving and resource allocation, which may reduce jitter and / or latency while increasing reliability.

[0039] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be interpreted as being limited to any specific structure or function presented throughout the present disclosure. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the disclosure.

[0040] Aspects and examples generally include methods, apparatus, network nodes, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, wireless communication devices, and / or processing systems as described or fully described herein with reference to the figures and description and as illustrated in the figures and description.

[0041] The present disclosure may be readily used as a basis for modifying or designing other structures for carrying out the same purpose of the present disclosure. Such equivalent constructions do not depart from the scope of the appended claims. The characteristics of the concepts disclosed herein (both their organization and method of operation) and the associated advantages are better understood from the following description when considered in conjunction with the accompanying drawings. Each of the figures in the accompanying drawings is provided for the purpose of illustration and description and not as a definition of limitations to the claims.

[0042] Although various aspects are described in the present disclosure by illustrating some examples, such aspects can be implemented in many different arrangements and scenarios. The technology described herein can be implemented using different platform types, devices, systems, shapes, sizes and / or packaging arrangements. For example, some aspects can be implemented via integrated chip implementations or other devices based on non-module components (e.g., end-user devices, vehicles, communication equipment, computing equipment, industrial equipment, retail / shopping equipment, medical equipment and / or artificial intelligence devices). Various aspects can be implemented in chip-level components, modular components, non-modular components, non-chip-level components, device-level components and / or system-level components. The equipment incorporating the various aspects and features described may include additional components and features for implementing and practicing the various aspects claimed and described. For example, the transmission and reception of wireless signals may include one or more components (e.g., hardware components, including antennas, radio frequency (RF) chains, power amplifiers, modulators, buffers, processors, interleavers, adders and / or summers) for analog and digital purposes. The various aspects described herein can be practiced in various devices, components, systems, distributed arrangements and / or end-user devices of different sizes, shapes and compositions.

[0043] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0044] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).

[0045] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one UE 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). For another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0046] In some examples, the network node 110 is or includes a network node (such as an RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0047] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. The network node may support one or more (e.g., three) cells. In some examples, the cell may not necessarily be stationary, and the geographic area of ​​the cell may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0048] In some aspects, the term "base station" or "network node" may refer to a converged base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near-RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions, such as those described herein in conjunction with the network node 110. In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the performance of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions, but not another base station function. In this way, a single device may include more than one base station.

[0049] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0050] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0051] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0052] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.

[0053] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, a processor component and a memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0054] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0055] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0056] The electromagnetic spectrum is typically subdivided by frequency / wavelength into various categories, bands, channels, etc. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that, although a portion of FR1 is greater than 6 GHz, FR1 is often (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 often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0057] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz to 24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz to 71GHz), FR4 (52.6GHz to 114.25GHz) and FR5 (114.25GHz to 300GHz). Each of these higher frequency bands falls within the EHF band.

[0058] With the above examples in mind, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0059] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive a DCI including a DFI field indicating at least one DFI value; terminate HARQ retransmission operations associated with the DRX cycle based on receiving the DCI; and transition from a first state to a second state based on terminating the HARQ retransmission operations, wherein the second state includes a power saving state. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0060] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send configuration information indicating a DCI field of a DCI format; and send a DCI corresponding to the DCI format, wherein the DCI includes a DFI field, wherein the DFI field indicates at least one DFI value, the at least one DFI value indicating that the UE 120 is to terminate a HARQ retransmission operation associated with a DRX cycle, wherein the configuration information indicates that the UE is to transition from a first state to a second state based on the termination of the HARQ retransmission operation, wherein the second state includes a power saving state. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0061] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The content described is different.

[0062] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0063] At the network node 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQI) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0064] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0065] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0066] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0067] Each of the antenna elements may include one or more sub-elements for radiating or receiving radio frequency signals. For example, a single antenna element may include a first sub-element that is cross-polarized with a second sub-element, which can be used to independently transmit cross-polarized signals. The antenna elements may include patch antennas, dipole antennas, or other types of antennas arranged in a linear pattern, a two-dimensional pattern, or another pattern. The spacing between antenna elements may allow signals having a desired wavelength transmitted individually by the antenna elements to interact or interfere (e.g., to form a desired beam). For example, given a desired wavelength or frequency range, the spacing may provide a quarter wavelength, half wavelength, or other fraction of a wavelength of the spacing between adjacent antenna elements to allow interaction or interference of signals transmitted by individual antenna elements within the desired range.

[0068] Antenna elements and / or sub-elements may be used to generate beams. A "beam" may refer to a directional transmission, such as a wireless signal transmitted in the direction of a receiving device. A beam may include a directional signal, a direction associated with the signal, a set of directional resources associated with the signal (e.g., angle of arrival, horizontal direction, vertical direction), and / or a set of parameters indicating one or more aspects of the directional signal, the direction associated with the signal, and / or the set of directional resources associated with the signal.

[0069] As indicated above, antenna elements and / or sub-elements can be used to generate beams. For example, antenna elements can be individually selected or deselected for transmission of a signal (or multiple signals) by controlling the amplitude of one or more corresponding amplifiers. Beamforming includes generating beams using multiple signals on different antenna elements, wherein one or more or all of the multiple signals are shifted in phase relative to each other. The formed beams may carry physical or higher layer reference signals or information. When each of the multiple signals is radiated from the corresponding antenna element, the radiated signals interact, interfere (constructively and destructively) and amplify with each other to form the resulting beam. The shape (such as amplitude, width and / or the presence of side lobes) and direction (such as the angle of the beam relative to the surface of the antenna array) can be dynamically controlled by modifying the phase shift or phase offset of the multiple signals relative to each other.

[0070] Beamforming may be used for communication between a UE and a base station, such as for millimeter wave communication, etc. In this case, the base station may provide the UE with a configuration of a transmit configuration indicator (TCI) state, which respectively indicates beams that may be used by the UE, such as for receiving a physical downlink shared channel (PDSCH). The base station may indicate an activated TCI state to the UE, and the UE may use the activated TCI state to select a beam for receiving the PDSCH.

[0071] The beam indication may be or include a TCI state information element, a beam identifier (ID), spatial relationship information, a TCI state ID, a closed loop index, a panel ID, a TRP ID, and / or a sounding reference signal (SRS) set ID, etc. The TCI state information element (referred to herein as TCI state) may indicate information associated with a beam such as a downlink beam. For example, the TCI state information element may indicate a TCI state identifier (e.g., tci-StateID), a quasi-co-location (QCL) type (e.g., qcl-Type1, qcl-Type2, qcl-TypeA, qcl-TypeB, qcl-TypeC, qcl-TypeD, etc.), a cell identifier (e.g., ServCellIndex), a bandwidth part identifier (bwp-Id), a reference signal identifier (such as CSI-RS (e.g., NZP-CSI-RS-ResourceId, SSB-Index, etc.)), etc. The spatial relationship information may similarly indicate information associated with an uplink beam.

[0072] The beam indication may be a joint or separate downlink (DL) / uplink (UL) beam indication in a unified TCI framework. In some cases, the network may support layer 1 (L1) based beam indication using at least UE-specific (unicast) DCI to indicate a joint or separate DL / UL beam indication from an active TCI state. In some cases, existing DCI formats 1_1 and / or 1_2 may be reused for beam indication. The network may include a support mechanism for the UE to confirm successful decoding of the beam indication. For example, an ACK / NACK (ACK / NACK) for a PDSCH scheduled by a DCI carrying a beam indication may also be used as an ACK for the DCI.

[0073] Beam indication may be provided for carrier aggregation (CA) scenarios. In a unified TCI framework, the network may support common TCI state ID updates and activations to provide common QCL information and / or one or more common UL transmit spatial filters across a set of configured component carriers (CCs). This type of beam indication may be applicable to intra-band CA as well as joint DL / UL beam indication and separate DL / UL beam indication. A common TCI state ID may mean that a reference signal (RS) determined according to a TCI state indicated by a common TCI state ID is used to provide a QCL type D indication and determine a UL transmit spatial filter across a set of configured CCs.

[0074] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0075] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0076] In some aspects, the controller / processor 280 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be communicated to other systems or components, such as the UE 120. For example, the processing system of the UE 120 may be a system that includes various other components or subcomponents of the UE 120.

[0077] The processing system of UE 120 may interface with one or more other components of UE 120, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of UE 120 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that UE 120 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that UE 120 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0078] In some aspects, controller / processor 240 may be a component of a processing system. A processing system may generally be a system or series of machines or components that receives inputs and processes the inputs to produce a set of outputs that may be passed to other systems or components, such as network node 110. For example, a processing system of network node 110 may be a system that includes various other components or subcomponents of network node 110.

[0079] The processing system of the network node 110 may interface with one or more other components of the network node 110, may process information (such as input or signal) received from one or more other components, or may output information to one or more other components. For example, a chip or modem of the network node 110 may include: a processing system, a first interface for receiving or obtaining information, and a second interface for outputting, sending, or providing information. In some examples, the first interface may be an interface between a processing system and a receiver of the chip or modem, so that the network node 110 may receive information or signal input, and may pass information to the processing system. In some examples, the second interface may be an interface between a processing system and a transmitter of the chip or modem, so that the network node 110 may send information output from the chip or modem. A person of ordinary skill in the art will readily recognize that the second interface may also obtain or receive information or signal input, and the first interface may also output, send, or provide information.

[0080] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the network node 110 may perform one or more techniques associated with early termination of hybrid automatic repeat request retransmissions, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 8 The process of 800 Fig. 9 900 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 8 The process of 800 Fig. 9 The process 900 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0081] In some aspects, the UE 120 includes means for receiving a DCI including a DFI field indicating at least one DFI value; means for terminating a HARQ retransmission operation associated with a discontinuous reception cycle based on receiving the DCI; and / or means for transitioning from a first state to a second state based on terminating the HARQ retransmission operation, wherein the second state includes a power saving state. The means for the UE to perform the operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0082] In some aspects, the network node includes means for sending configuration information indicating a DFI field of a DCI format; and / or means for sending a DCI corresponding to a DCI format, wherein the DCI includes a DFI field, wherein the DFI field indicates at least one DFI value, the at least one DFI value indicating that the UE 120 is to terminate a HARQ retransmission operation associated with a discontinuous reception cycle, wherein the configuration information indicates that the UE 120 is to transition from a first state to a second state based on the termination of the HARQ retransmission operation, wherein the second state includes a power saving state. Means for the network node to perform operations described herein may include, for example, one or more of the following: a communication manager 150, a transmit processor 220, a TX MIMO processor 230, a modem 232, an antenna 234, a MIMO detector 236, a receive processor 238, a controller / processor 240, a memory 242, or a scheduler 246.

[0083] Although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0084] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The content described is different.

[0085] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways using various components or constituent parts. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station, or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP, or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. A "network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0086] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other network nodes. A DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0087] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0088] Figure 33 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective RF access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0089] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 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 one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0090] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 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, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.

[0091] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partitioning (such as that defined by 3GPP). In some aspects, the one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0092] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions, or low PHY layer functions (such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc.) based on functional splitting (e.g., functional splitting defined by 3GPP). In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0093] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 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 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) 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 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0094] The non-RT RIC 315 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 325. The non-RT RIC 315 may be coupled to or communicate with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 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 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0095] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0096] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The content described is different.

[0097] Figure 4 4 is a diagram illustrating an example 400 associated with a DRX configuration according to the present disclosure. As shown by reference numeral 402, the network node 110 may send a DRX configuration to the UE 120 to configure a DRX cycle 405 for the UE 120. The DRX cycle 405 may include a DRX on-duration 410 (e.g., during which the UE 120 is awake or active) and an opportunity to enter a DRX sleep state 415. As used herein, the time during which the UE 120 is configured to be active including the DRX on-duration 410 may be referred to as a DRX active time 420, and the time during which the UE 120 is configured to be in the DRX sleep state 415 may be referred to as an inactive time. As described below, the UE 120 may monitor the PDCCH during the DRX active time 420, and may avoid monitoring the PDCCH during the inactive time.

[0098] During the DRX on duration 410, the UE 120 may monitor a downlink control channel (e.g., a PDCCH), as indicated by reference numeral 425. For example, the UE 120 may monitor the PDCCH for DCI related to the UE 120. If the UE 120 does not detect and / or successfully decode any PDCCH communication intended for the UE 120 during the DRX on duration 410, the UE 120 may enter a sleep state 415 (e.g., an inactive time) at the end of the DRX on duration 410, as indicated by reference numeral 430. In this way, the UE 120 may conserve battery power and reduce power consumption. As shown, the DRX cycle 405 may repeat at a configured periodicity according to the DRX configuration.

[0099] If the UE 120 detects and / or successfully decodes a PDCCH communication intended for the UE 120, the UE 120 may remain in an active state (e.g., awake) for the duration of the DRX IAT 435 (e.g., this may extend the DRX active time 420). The duration of the DRX IAT 435 may be referred to as a DRX IAT duration. The DRX IAT duration 435 may include a DRX HARQ retransmission timer and / or a DRX retransmission timer. The UE 120 may start the DRX IAT 435 at the time when the PDCCH communication is received (e.g., in a transmit time interval (TTI) such as a time slot or subframe in which the PDCCH communication is received). The UE 120 may remain in an active state until the DRX IAT 435 expires, at which time the UE 120 may enter a sleep state 415 (e.g., during an inactive time), as shown by reference numeral 440. During the duration of the DRX IAT 435, the UE 120 may continue to monitor the PDCCH communication, may obtain downlink data communications scheduled by the PDCCH communication (e.g., on a downlink data channel such as the PDSCH), and / or may prepare and / or transmit uplink communications scheduled by the PDCCH communication (e.g., on a physical uplink shared channel (PUSCH)). The UE 120 may restart the DRX IAT 435 each time a PDCCH communication of the UE 120 is detected for an initial transmission (e.g., but not for a retransmission).

[0100] As shown by reference numeral 440, UE 120 and network node 110 may communicate with each other. The communication may involve XR communication. Some periodic communications such as XR communications may be inherently variable. For example, as shown in conjunction with the first XR service flow 445, XR communication may be associated with the number of packets 450 per service burst 455 and the variability of the size of each packet 450. XR communication may also be associated with a non-integer period 460 (e.g., 1 / 60 frame per second = 16.67ms period and 1 / 120fps = 8.33ms period). As another example, the arrival time 465 of the XR service may vary due to jitter 470 and may not correspond to the expected arrival time 475. Jitter is the variation or uncertainty of the arrival time of a communication, such as the expected or observed deviation of the actual arrival time of a packet relative to the scheduled arrival time of the packet. As yet another example, multiple service flows of XR communication may have variable parameters and characteristics, such as different data rates, different delay or reliability requirements, different packet sizes, etc. For example, as shown, the second XR traffic flow 480 may have a different number of packets 450 per traffic burst 455 and a different non-integer period 485 , which may result in a different jitter 470 than the jitter of the first XR traffic flow 445 .

[0101] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The content described is different.

[0102] In some cases, a restricted PDB may be established for XR video frames (e.g., for AR / VR, the delay budget from the time a video frame arrives at a network node to the time the video frame is successfully transmitted to the UE may be 10ms). Using some dynamic signaling (e.g., wake-up signal and / or scheduling DCI, etc.) to indicate the data arrival time and the number of time slots of the physical data communication channel used to send the data may better accommodate jitter and variable frame sizes.

[0103] Figure 5 is a diagram illustrating an example 500 associated with communication of an XR service according to the present disclosure.

[0104] As shown by reference numeral 505, an early burst arrival of XR data at a network node (e.g., XR data arrives near a first end of a jitter distribution) can cause delays at a buffer (e.g., a downlink buffer) to increase relative to an on-time burst arrival (as shown by reference numeral 510) because scheduling a physical data communication channel for sending data associated with the burst can occur near the expected arrival time, near the center of the jitter distribution. In some cases, early burst arrivals can occur outside of the DRX On Duration, which can result in delayed reception of the XR data. As shown by reference numeral 515, late burst arrivals (which can occur outside of the DRX On Duration) can result in delays within the PDB and inefficient consumption of power resources prior to arrival.

[0105] As shown by reference numeral 520, a DRX retransmission timer may be started after a burst arrives at the UE. Once the DRX retransmission timer is started, even if the network does not intend to schedule retransmissions, the UE monitors the PDCCH based on the HARQ process according to the configuration, which may result in unnecessary power consumption of the UE. With deadline-aware scheduling, some HARQ retransmissions may not be scheduled before the burst deadline, which may also result in unnecessary power consumption of the UE.

[0106] In some cases, a DFI indication may be used to facilitate a configured grant operation. For example, a UE may be configured with multiple search space sets to monitor the PDCCH to detect DCI format 0_1 ​​with a DFI flag field and a cyclic redundancy check (CRC), which is scrambled with the cs-RNTI provided by the configured scheduling (CS)-radio network temporary identifier (RNTI). If the PUSCH transmission is configured by ConfiguredGrantConfig, the UE may determine that the DCI format provides HARQ-ACK information for the PUSCH transmission based on when the DFI flag field value is set to "1". For the UE's initial transmission of a transport block in the PUSCH configured by ConfiguredGrantConfig, if the UE receives a CG-DFI providing HARQ-ACK information for the transport block, the UE may assume that the transport block has been correctly decoded if the HARQ-ACK information value is ACK; otherwise, the UE may assume that the transport block has not been correctly decoded. For PUSCH transmissions scheduled by the DCI format, if the UE receives a CG-DFI providing HARQ-ACK information for a transport block, the UE may assume that the transport block has been correctly decoded if the HARQ-ACK information value is ACK; otherwise, the UE may assume that the transport block has not been correctly decoded.

[0107] Some of the techniques described herein provide early termination of HARQ retransmission operations associated with DRX based on receiving a DCI containing a DFI, which is configured for downlink and / or uplink early HARQ termination for the purpose of saving power in scenarios involving variable communication time such as XR communications. For example, in some aspects, the UE may receive a DCI including a DFI field indicating a DFI value. The UE may terminate the HARQ retransmission operation based on receiving the DCI. The UE may transition from a first state to a second state based on terminating the HARQ retransmission operation, wherein the second state is a power saving state. In some aspects, the UE may terminate the HARQ retransmission operation by terminating the HARQ retransmission timer and / or by refreshing the HARQ buffer corresponding to the HARQ retransmission operation. In this way, some aspects described herein may facilitate termination of the HARQ retransmission operation before the end of the DRX active time, thereby improving resource allocation efficiency and reducing the power consumption of the UE. Therefore, some aspects may facilitate XR-specific power saving and resource allocation, which may reduce jitter and / or latency while increasing reliability.

[0108] In some aspects, for example, the UE may be configured with a DFI field in a DCI format to end HARQ retransmissions in a DRX cycle for power saving purposes. The DCI format may be a downlink DCI format 1_1 and / or an uplink DCI format 0_1, and may be scrambled by a cell-RNTI (C-RNTI), a CS-RNTI, and / or an MCS-RNTI. If the DCI is a downlink DCI, the DCI may include a DFI tag field and a field including a HARQ-ACK bitmap. The HARQ-ACK bitmap may include 16 bits or 32 bits, depending on the UE capability. In some aspects, all remaining bits may be set to 0. If the DCI is an uplink DCI, the DCI may include a DFI tag field and a field including a HARQ-ACK bitmap with 16 bits. In some aspects, all remaining bits may be set to 0. The mapping order of the bitmap to the HARQ process index may be configured so that the HARQ process index is mapped in ascending order from the most significant bit (MSB) to the least significant bit (LSB) according to the bitmap.

[0109] In some aspects, for example, when a UE receives a DCI with a DFI flag field set to 1, for each bit of the bitmap, a value of 1 indicates ACK, which means that the corresponding HARQ retransmission may be ended (e.g., by ending the HARQ retransmission timer and ending the retransmission timer in the DRX cycle and / or by flushing the HARQ buffer) to save power. In some aspects, the UE may terminate the timer after a configured and / or indicated amount X symbols from the DCI. In some aspects, a value of 0 in the bitmap may indicate a NACK, and the UE may refrain from prematurely terminating the HARQ retransmission operation based on the NACK.

[0110] Some aspects described herein may be implemented based on a rule indicating that for a PDSCH transmission scheduled by a DCI format, or for an initial transmission of a transport block by a UE in a PDSCH configured by an SPSConfig, if the UE receives a DFI providing ACK information for the transport block, then the UE may flush the buffer for the transport block; otherwise, the UE may not flush the buffer for the transport block. In some aspects, the rule may indicate that for a PUSCH transmission scheduled by a DCI format, or for an initial transmission of a transport block by a UE in a PUSCH configured by a ConfiguredGrantConfig, if the UE receives a DFI providing ACK information for the transport block, then the UE may flush the buffer for the transport block; otherwise, the UE may not flush the buffer for the transport block.

[0111] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The content described is different.

[0112] Figure 6 6 is a diagram illustrating an example 600 associated with early termination of HARQ retransmission operations according to the present disclosure. Figure 6 As shown, UE 602 and network node 604 can communicate with each other. In some aspects, UE 602 can be, similar to, or include Figures 1 to 3 The depicted UE 120 may be, or be included in, the UE. In some aspects, the network node 604 may be, be similar to, or include Figure 1 and Figure 2 The depicted network node 110 and / or Figure 3 One or more components of the depicted decomposed base station architecture 300 may be included in the network node and / or the one or more components.

[0113] As indicated by reference numeral 606, the UE 602 may send capability information and the network node 604 may receive the capability information. The capability information may indicate one or more capabilities of the UE 602. For example, the capability information may indicate the capability of the UE 602 to receive and decode a HARQ bitmap having an indication of the amount of bits (e.g., 16 bits and / or 32 bits, etc.). In some aspects, the capability information may indicate the capability of the UE 602 to receive a DFI.

[0114] As shown by reference numeral 608, the network node 604 may send configuration information and the UE 602 may receive the configuration information. In some aspects, the configuration information may be carried in an RRC message. The configuration information may include a DRX configuration. In some aspects, the configuration information may indicate a configuration for a DFI field in the DCI. In some aspects, the configuration information may indicate a set of potential time offset values ​​associated with terminating HARQ retransmission operations based on receiving the DFI. For example, the time offset value may correspond to a time period between receiving the DFI and transitioning from a first state to a second state. In some aspects, the DCI transmission may indicate a time offset for the set of potential time offset values.

[0115] As shown by reference numeral 610, the UE 602 and the network node 604 may communicate with each other during the DRX active time corresponding to the DRX configuration. In some aspects, the UE 602 and the network node 604 may communicate XR data during the DRX active time. Communication may refer to sending and / or receiving signals. As shown by schematic representation 612, the DRX active time may include a time period starting at the beginning of the DRX on duration 614 and ending at the expiration of the DRX retransmission timer duration 616.

[0116] As shown, a first transport block 618 associated with a first HARQ process (shown as “HARQ 0”) may be received during the DRX active time. Based on the reception of the first transport block 618, the UE 602 may start a DRX HARQ retransmission timer duration 620, and after a configured offset, the UE 602 may start a DRX retransmission timer duration 622, which may run continuously after the DRX HARQ retransmission timer duration 620, or at least partially concurrently with the DRX HARQ retransmission timer duration 620. Similarly, a second transport block 624 associated with a second HARQ process (shown as “HARQ 1”) may be received during the DRX active time. Based on reception of the first transport block 618, the UE 602 may start a DRX HARQ retransmission timer duration 626, and after a configured offset, the UE 602 may start a DRX retransmission timer duration 616, which may run continuously after the DRX HARQ retransmission timer duration 626 or at least partially concurrently with the DRX HARQ retransmission timer duration 626. During the DRX retransmission timer durations 622 and 616, the UE 602 may be active to receive grants associated with the corresponding HARQ process (e.g., for retransmissions).

[0117] As shown by reference numeral 630, the network node 604 may send a DCI 632 including a DFI field, and the UE 602 may receive the DCI. The DFI field may indicate at least one DFI value. In some aspects, the DCI 632 may correspond to a downlink DCI format 1_1 or a downlink DCI format 0_1. In some aspects, the DCI may be scrambled by a C-RNTI, a CS-RNTI, or an MCS-RNTI. In some aspects, the DFI field may include a DFI flag field and a HARQ-ACK bitmap. Any bit not associated with the DFI field or the HARQ-ACK bitmap may be set to 0.

[0118] In some aspects, the DCI 632 may correspond to a downlink DCI format, and the HARQ-ACK bitmap may include 16 bits or 32 bits. In some aspects, the DCI 632 may correspond to an uplink DCI format, and the HARQ-ACK bitmap may include 16 bits. In some aspects, the order associated with the mapping between multiple bits of the HARQ-ACK bitmap and multiple HARQ process indexes may include an ascending order from the MSB of the bitmap to the LSB of the bitmap. In some aspects, the DFI flag field may include a first value, and a bit of the HARQ-ACK bitmap indicating the first value may indicate ACK. In some aspects, whether to perform a HARQ retransmission operation corresponds to a bit of the HARQ-ACK bitmap. In some aspects, the DCI 632 may also indicate an offset 634 associated with terminating one or more HARQ retransmission operations.

[0119] As shown by reference numeral 636, the UE 602 may terminate the HARQ retransmission operation. The HARQ retransmission operation may be associated with a DRX cycle and may be terminated at a termination time 638 based on receiving the DCI 632. As shown, the termination time 638 may occur before the burst deadline 640. In some aspects, the UE 602 may terminate the HARQ retransmission operation based on ending the HARQ retransmission timer 622 and / or 616. In some aspects, the UE 602 may terminate the HARQ retransmission operation based on flushing a HARQ buffer corresponding to the HARQ retransmission operation.

[0120] In some aspects, the DFI may correspond to only one connected mode DRX (CDRX) cycle. For example, DCI 632 may include only one bit indicating the DFI. In some aspects, the DFI may correspond to multiple CDRX cycles. For example, DCI 632 may correspond to the indicated DCI format (e.g., DCI format 1_1 and / or DCI format 0_1), and the DFI may include a bitmap of a size equal to the number of CDRX groups associated with the set of configured CDRX groups. Each group may correspond to one or more CCs and / or HARQ processes. In some aspects, the bitmap may include multiple bits, each of which corresponds to a CDRX group in the set of configured CDRX groups. A first value (e.g., "0") of a bit in a plurality of bits may indicate that the corresponding CDRX group will remain active, and a second value (e.g., "1") of the bit may indicate that the corresponding CDRX group will terminate the HARQ retransmission operation associated with the CDRX group.

[0121] As shown by reference numeral 642, UE 602 may transition from the first state to the second state. UE 602 may transition from the first state to the second state based on terminating HARQ retransmission operation. The second state may include a power saving state in which one or more components of UE 602 are in a dormant state (e.g., deactivated).

[0122] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 The content described is different.

[0123] Figure 7is a diagram of example 700 illustrating early termination of HARQ retransmission operations according to the present disclosure. As shown, multiple DCI transmissions (shown as "DCI n", "DCI n+1", and "DCI n+2") may be received. Based on the reception of each DCI transmission, a corresponding HARQ process (shown as "HARQ n", "HARQ n+1", and "HARQ n+2") may be triggered so that the corresponding HARQ-ACK / NACK is stored in the HARQ buffer. As shown, the HARQ buffer may be aggregated each time a HARQ process occurs, resulting in the buffer including all three (or more) HARQ-ACK / NACKs after the third HARQ process HARQ n+2 is triggered. As shown, a DCI including a DFI having a value of 1 may be received, and the UE may refresh the corresponding HARQ buffer based on the reception of the DCI. In this example, the DFI indicates a DFT value of 1, and the bitmap 110 mapped for HARQ n, n+1, and n+2, the UE can refresh HARQ n and n+1, and maintain HARQ n+2. In this way, the UE can save power resources by removing bits from the buffer after receiving the DCI, because maintaining bits in the buffer can result in consumption of power resources.

[0124] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The content described is different.

[0125] Figure 8 is a diagram illustrating an example process 800 performed, for example, by a UE in accordance with the present disclosure. Example process 800 is an example in which a UE (eg, UE 602) performs operations associated with early termination of HARQ retransmissions.

[0126] like Figure 8 As shown, in some aspects, process 800 may include receiving a DCI that includes a DFI field indicating at least one DFI value (block 810). For example, a UE (e.g., using Fig.10 The communications manager 1008 and / or receiving component 1002 depicted in FIG. 1004 may receive a DCI that includes a DFI field indicating at least one DFI value, as described above.

[0127] like Figure 8 As further shown, in some aspects, process 800 may include terminating HARQ retransmission operations associated with a discontinuous reception cycle based on receiving the DCI (block 820). Fig.10The communication manager 1008, receiving component 1002 and / or sending component 1004 depicted in the figure can terminate HARQ retransmission operations associated with the discontinuous reception cycle based on receiving the DCI, as described above.

[0128] like Figure 8 As further shown, in some aspects, process 800 may include transitioning from a first state to a second state based on terminating HARQ retransmission operations, wherein the second state includes a power saving state (block 830). Fig.10 The communication manager 1008, receiving component 1002 and / or sending component 1004 depicted in the figure can transition from a first state to a second state based on terminating HARQ retransmission operations, where the second state includes a power saving state, as described above.

[0129] Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in combination with one or more other processes described elsewhere herein.

[0130] In a first aspect, the DCI corresponds to a downlink DCI format 1_1 or a downlink DCI format 0_1. In a second aspect, alone or in combination with the first aspect, the DCI is scrambled by a C-RNTI, a CS-RNTI, or an MCS-RNTI. In a third aspect, alone or in combination with one or both of the first and second aspects, the DFI field includes a DFI flag field and a HARQ-ACK bitmap. In a fourth aspect, alone or in combination with the third aspect, any bit not associated with the DFI field or the HARQ-ACK bitmap is set to 0. In a fifth aspect, alone or in combination with one or more of the third or fourth aspects, the DCI corresponds to a downlink DCI format, and wherein the HARQ-ACK bitmap includes 16 bits or 32 bits.

[0131] In a sixth aspect, alone or in combination with one or more of the third to fifth aspects, process 800 includes sending UE capability information indicating a bitmap capability, wherein the HARQ-ACK bitmap includes 16 bits or 32 bits based on the UE capability. In a seventh aspect, alone or in combination with the third aspect, the DCI corresponds to an uplink DCI format, and wherein the HARQ-ACK bitmap includes 16 bits.

[0132] In an eighth aspect, alone or in combination with one or more of the third aspect or the seventh aspect, an order associated with a mapping between a plurality of bits of a HARQ-ACK bitmap and a plurality of HARQ process indices comprises an ascending order from a most significant bit of the bitmap to a least significant bit of the bitmap. In a ninth aspect, alone or in combination with one or more of the third aspect, the seventh aspect or the eighth aspect, a DFI flag field comprises a first value, and wherein a bit of the HARQ-ACK bitmap indicating the first value indicates confirmation. In a tenth aspect, alone or in combination with the ninth aspect, whether a HARQ retransmission operation is performed corresponds to a bit of the HARQ-ACK bitmap.

[0133] In an eleventh aspect, either alone or in combination with one or more of the first to tenth aspects, terminating the HARQ retransmission operation includes ending a HARQ retransmission timer. In a twelfth aspect, either alone or in combination with one or more of the first to eleventh aspects, terminating the HARQ retransmission operation includes flushing a HARQ buffer corresponding to the HARQ retransmission operation. In a thirteenth aspect, either alone or in combination with one or more of the first to twelfth aspects, process 800 includes receiving configuration information indicating a DFI field.

[0134] although Figure 8 An example block diagram of process 800 is shown, but in some aspects, process 800 may include Figure 8 The blocks depicted may be additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted. Additionally or alternatively, two or more of the blocks of process 800 may be performed in parallel.

[0135] Fig. 9 is a diagram illustrating an example process 900, performed, for example, by a network node, in accordance with the present disclosure. Example process 900 is an example in which a network node (eg, network node 604) performs operations associated with early termination of HARQ retransmissions.

[0136] like Fig. 9 As shown, in some aspects, process 900 may include sending configuration information indicating a DFI field of a DCI format (block 910).
