Techniques for predicting network node transmission configuration indicator status

Abstract

Aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may receive a medium access control (MAC) control element (CE) indication that activates a network node predicted transmit configuration indicator (TCI) state. The UE may transmit an acknowledgement (ACK) associated with the MAC CE indication. The UE may receive downlink control information (DCI) indicating a predicted TCI state of the network node of a subsequent communication, the DCI scheduling the subsequent communication at a scheduling time based at least in part on a threshold amount of time from the indication from the ACK or from the MAC CE. Numerous other aspects are described.

Description

Technical Field

[0001] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for predicting a state of a network node sending a configuration indicator.

[0002] Related technologies

[0003] 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).

[0004] 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. A UE may communicate with a network node 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 side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, among other examples).

[0005] These 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, or global level. New Radio (NR), which may also 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 using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using CP-OFDM or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM) on the uplink, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards.

[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 construed as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be appreciated by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functions, or structures and functions in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present invention.

[0040] 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 these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0041] 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 applied to other RATs, such as 3G RAT, 4G RAT and / or post-5G (e.g., 6G) RAT.

[0042] Figure 11 is a diagram illustrating an example of a wireless network 100. The wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network or 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 an example of 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 RAN node (e.g., within a single device or unit). As another example, the network node 110 may be a disaggregated network node (sometimes referred to as a disaggregated 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)).

[0043] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. 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. For example, the network node 110 may include 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.

[0044] 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 or a 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, or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) 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 residence) 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 in , 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. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0045] In some aspects, the term "base station" or "network node" may refer to an aggregated 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 execution 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 the other. In this way, a single device may include more than one base station.

[0046] The wireless network 100 may include one or more relay stations. A relay station is a network node that receives transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmits 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.

[0047] 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, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different effects on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 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 to 2 watts).

[0048] 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.

[0049] UE 120 can be dispersed throughout the wireless network 100, and each UE 120 can be fixed or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station, 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 device, 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, 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, or any other suitable device configured to communicate via a wireless or wired medium.

[0050] Some UE 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UE. MTC UE or eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor or a location tag, which may communicate with a network node, another device (e.g., a remote device) or some other entity. Some UE 120 may be considered as an Internet of Things (IoT) device, or may be implemented as a NB-IoT (narrowband IoT) device. Some UE 120 may be considered as customer site equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component or a memory component. In some examples, the processor component and the 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 operationally coupled, communicatively coupled, electronically coupled, or electrically coupled.

[0051] 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 also be referred to as a radio technology or air interface. Frequency may also be referred to as a carrier or frequency channel. 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.

[0052] 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), or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by network node 110.

[0053] Devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, or channels by frequency or wavelength. For example, devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). Although a portion of FR1 is greater than 6 GHz, FR1 is often (interchangeably) referred to as the “below 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, 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).

[0054] The 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-24.25GHz). The frequency bands falling within FR3 can inherit FR1 characteristics or FR2 characteristics, and thus the features of FR1 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-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0055] With these examples in mind, unless otherwise specifically stated, if the term "sub-6 GHz" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, frequencies that may be within FR1, or frequencies that may include mid-band frequencies. Additionally, unless otherwise specifically stated, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, frequencies that may be within FR2, FR4, FR4-a, FR4-1, or FR5, or frequencies that 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, or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0056] In some aspects, the UE 120 may include a communications manager 140. As described in more detail elsewhere herein, the communications manager 140 may receive a MAC CE indication activating a transmit configuration indicator (TCI) state predicted by a network node; send an acknowledgement (ACK) associated with the MAC CE indication; and receive downlink control information (DCI) indicating the TCI state predicted by the network node for subsequent communications, the DCI scheduling the subsequent communications at a scheduling time based at least in part on a threshold amount of time from the ACK or from the MAC CE indication. As described in more detail elsewhere herein, the communications manager 140 may send an indication of support for receiving a DCI-based indication of a TCI state predicted by a network node; and receive a DCI-based indication of a TCI state predicted by a network node. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0057] In some aspects, the network node 110 may include a communications manager 150. As described in more detail elsewhere herein, the communications manager 150 may send a MAC CE indication to the UE that activates a TCI state predicted by the network node; receive an ACK associated with the MAC CE indication; and send a DCI indicating the TCI state predicted by the network node for subsequent communications, the DCI scheduling the subsequent communications at a scheduling time based at least in part on a threshold amount of time from the ACK or from the MAC CE indication. As described in more detail elsewhere herein, the communications manager 150 may receive an indication from the UE of support for receiving a DCI-based indication of a TCI state predicted by the network node; and send a DCI-based indication of a TCI state predicted by the network node. Additionally or alternatively, the communications manager 150 may perform one or more other operations described herein.

[0058] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 Different from what is described.

[0059] 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. 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.

[0060] 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 use one or more channel quality indicators (CQIs) received from the UE 120 to select one or more modulation and coding schemes (MCSs) for the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 using the MCS selected for the UE 120 and may provide data symbols to the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, 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-decoding) on ​​data symbols, control symbols, overhead symbols, or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a set of corresponding 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, 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 set of corresponding antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0061] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 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, 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 a data sink 260, and may provide decoded control information and system information to a 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, or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in a housing.

[0062] 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.

[0063] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or may be included in one or more antenna panels, one or more antenna groups, one or more group antenna elements, or one or more antenna arrays, etc. An antenna panel, antenna group, set of antenna elements, or antenna array may include one or more antenna elements (in a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, or coupled to one or more transmit or receive components (such as Figure 2 One or more antenna elements of one or more components).

[0064] 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, 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, 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 processes described herein (eg, with reference to Figures 6 to 14 ).

[0065] At the network node 110, uplink signals from the UE 120 or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232, shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted via the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide the decoded control information to the controller / processor 240. The 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 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, 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 processes described herein (e.g., reference 20 to FIG. 1 ). Figures 6 to 14 ).

[0066] 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 input and processes the input 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.

[0067] 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 of the chip or modem and a receiver, 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 of the chip or modem and a transmitter, so that UE 120 may send information output from the chip or modem. One 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.

[0068] 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.

[0069] 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 the processing system of the chip or modem and a receiver, so that the network node 110 can receive information or signal input, and can pass information to the processing system. In some examples, the second interface may be an interface between the processing system of the chip or modem and a transmitter, so that the network node 110 can send information output from the chip or modem. Those 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.

[0070] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component (or combination of components) may perform or direct, for example Fig. 9 The process of 900 Fig.10 The process of 1000 Fig.11 Process 1100, Fig.12 1200 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 memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code or program code) for wireless communication. For example, one or more instructions, when executed (e.g., directly, or after compilation, conversion, or interpretation) by one or more processors of network node 110 or UE 120, may cause the one or more processors, UE 120, or network node 110 to perform or direct, for example, Fig. 9 The process of 900 Fig.10 The process of 1000 Fig.11 Process 1100, Fig.12 The operations of the process 1200 and / or other processes described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0071] In some aspects, the UE includes: a means for receiving a MAC CE indication of a TCI state predicted by a network node; a means for sending an ACK associated with the MAC CE indication; and / or a means for receiving a DCI indicating a TCI state predicted by a network node for a subsequent communication, the DCI scheduling the subsequent communication at a scheduling time based at least in part on a threshold amount of time from the ACK or from the MAC CE indication. In some aspects, the UE includes: a means for sending an indication of support for receiving a DCI-based indication of a TCI state predicted by a network node; and / or a means for receiving a DCI-based indication of a TCI state predicted by a network node. 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.

[0072] In some aspects, the network node includes: a means for sending a MAC CE indication to a UE to activate a TCI state predicted by the network node; a means for receiving an ACK associated with the MAC CE indication; and / or a means for sending a DCI indicating the TCI state predicted by the network node for subsequent communication, the DCI scheduling the subsequent communication at a scheduling time based at least in part on a threshold amount of time from the ACK or from the MAC CE indication. In some aspects, the base station includes: a means for receiving an indication from the UE of support for receiving a DCI-based indication of the TCI state predicted by the network node; and / or a means for sending a DCI-based indication of the TCI state predicted by the network node. The means for the base station to perform the 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.

[0073] Although Figure 2 The blocks in the 2000 and 2010 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.

[0074] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different from what is described.

[0075] The deployment of a communication system (such as a 5G NR system) can be arranged in a variety of ways with 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, a TRP or a cell, etc.) or one or more units (or one or more components) performing 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. "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).

[0076] 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.

[0077] 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.

[0078] Figure 33 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310 that may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated 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 radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0079] 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, the one or more interfaces being 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.

[0080] In some aspects, 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 CU 310. 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, CU310 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 310 may be implemented to communicate with DU 330 for network control and signaling.

[0081] 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 partition such as that defined by 3GPP. In some aspects, 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. 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.

[0082] 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 based on functional split (e.g., functional split defined by 3GPP) (such as lower layer functional split). 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).

[0083] The SMO framework 305 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 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 335) 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-RTRIC 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.

[0084] 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 in communication 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.

[0085] 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).

[0086] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different from what is described.

[0087] Figure 4 4 is a diagram illustrating examples 400, 410, and 420 of a channel state information (CSI) reference signal (CSI-RS) beam management process according to the present disclosure. Figure 4 As shown, examples 400, 410, and 420 include UE 120 communicating with network node 110 in a wireless network (e.g., wireless network 100). Figure 4 The devices shown are provided as examples, and the wireless network may support communication and beam management between other devices (e.g., between UE 120 and network node 110 or TRP, between mobile terminal node and control node, between IAB child node and IAB parent node, and / or between scheduled node and scheduling node). In some aspects, UE 120 and network node 110 may be in a connected state (e.g., RRC connected state).

[0088] like Figure 4 As shown in , example 400 may include a network node 110 (e.g., one or more network node devices such as RU, DU, and / or CU, among other examples) and a UE 120 that communicates with the UE to perform beam management using CSI-RS. Example 400 depicts a first beam management process (e.g., P1 CSI-RS beam management). The first beam management process may be referred to as a beam selection process, an initial beam acquisition process, a beam scanning process, a cell search process, and / or a beam search process. As shown in Figure 4 As shown in example 400, CSI-RS may be configured to be sent from network node 110 to UE 120. CSI-RS may be configured to be periodic (e.g., using RRC signaling), semi-persistent (e.g., using medium access control (MAC) control element (MAC-CE) signaling), and / or aperiodic (e.g., using DCI).

[0089] The first beam management process may include the network node 110 performing beam scanning on multiple transmit (Tx) beams. The network node 110 may transmit a CSI-RS using each transmit beam used for beam management. In order to enable the UE 120 to perform receive (Rx) beam scanning, the network node may transmit (e.g., repeat) each CSI-RS multiple times within the same reference signal resource set using a transmit beam, so that the UE 120 can sweep the receive beam in multiple transmit instances. For example, if the network node 110 has a set of N transmit beams and the UE 120 has a set of M receive beams, the CSI-RS may be transmitted M times on each of the N transmit beams, so that the UE 120 can receive M instances of the CSI-RS per transmit beam. In other words, for each transmit beam of the network node 110, the UE 120 may perform beam scanning on the receive beam of the UE 120. Thus, the first beam management process may enable UE 120 to measure CSI-RS on different transmit beams using different receive beams to support selection of a network node 110 transmit beam / UE 120 receive beam pair. UE 120 may report the measurements to network node 110 to enable network node 110 to select one or more beam pairs for communication between network node 110 and UE 120. Although example 400 has been described in conjunction with CSI-RS, the first beam management process may also use synchronization signal blocks (SSBs) to perform beam management in a similar manner as described above.

[0090] like Figure 4As shown, example 410 may include network node 110 and UE 120 communicating to perform beam management using CSI-RS. Example 410 depicts a second beam management procedure (e.g., P2 CSI-RS beam management). The second beam management procedure may be referred to as a beam refinement procedure, a network node beam refinement procedure, a TRP beam refinement procedure, and / or a transmit beam refinement procedure. Figure 4 As shown in example 410, the CSI-RS may be configured to be transmitted from the network node 110 to the UE 120. The CSI-RS may be configured to be non-periodic (e.g., using DCI). The second beam management process may include the network node 110 performing beam scanning on one or more transmit beams. The one or more transmit beams may be a subset of all transmit beams associated with the network node 110 (e.g., determined at least in part based on measurements reported by the UE 120 in conjunction with the first beam management process). The network node 110 may transmit the CSI-RS using each of the one or more transmit beams used for beam management. The UE 120 may measure each CSI-RS using a single (e.g., the same) receive beam (e.g., determined at least in part based on measurements performed in conjunction with the first beam management process). The second beam management process may enable the network node 110 to select the best transmit beam based at least in part on measurements of the CSI-RS reported by the UE 120 (e.g., measured by the UE 120 using a single receive beam).

[0091] like Figure 4 As shown, example 420 depicts a third beam management process (e.g., P3 CSI-RS beam management). The third beam management process may be referred to as a beam refinement process, a UE beam refinement process, and / or a receive beam refinement process. Figure 4As shown in example 420, one or more CSI-RS may be configured to be sent from the network node 110 to the UE 120. The CSI-RS may be configured to be non-periodic (e.g., using DCI). The third beam management process may include the network node 110 sending the one or more CSI-RS using a single transmit beam (e.g., determined at least in part based on measurements reported by the UE 120 in conjunction with the first beam management process and / or the second beam management process). In order to enable the UE 120 to perform receive beam scanning, the network node may use the transmit beam to send (e.g., repeat) the CSI-RS multiple times within the same reference signal resource set, so that the UE 120 can sweep across one or more receive beams in multiple transmission instances. The one or more receive beams may be a subset of all receive beams associated with the UE 120 (e.g., determined at least in part based on measurements performed in conjunction with the first beam management process and / or the second beam management process). The third beam management process may enable the network node 110 and / or the UE 120 to select the best receive beam based at least in part on reported measurements received from the UE 120 (e.g., the reported measurements are measurements of the CSI-RS of the transmit beam using the one or more receive beams).

[0092] As indicated above, Figure 4 is provided as an example of a beam management process. Other examples of beam management processes can be found in Figure 4 For example, UE 120 and network node 110 may perform the third beam management process before performing the second beam management process, and / or UE 120 and network node 110 may perform a similar beam management process to select a UE transmit beam.

[0093] Figure 5 is a diagram illustrating an example 500 of predicting TCI status according to the present disclosure.

[0094] The beam management process can improve communications in a wireless network by providing a mechanism to a network node and / or UE to identify a beam with better signal quality relative to other beams. Communicating via a wireless network using a beam with better signal quality relative to other beams can reduce recovery errors at the receiver, increase data throughput, and / or reduce data transmission latency (e.g., by reducing retransmissions). Various factors may cause the network node and UE to perform the beam management process multiple times, such as atmospheric changes, UE movement to a new location, and / or changes in interference associated with other devices. Repeated beam management processes may consume air interface resources (e.g., frequency resources and / or time resources) that the wireless network could have otherwise been directed to additional devices or used for other transmissions. Therefore, when the network node and UE perform each beam management process, the repeated beam management process may increase data transmission latency for other devices.

[0095] In order to reduce the signaling overhead and resource consumption associated with the beam management process, the network node 502 (shown as a base station in the example 500) may select a beam and / or beam pair associated with the TCI state based at least in part on a prediction algorithm. For example, the network node 502 may include one or more models 504 trained using a machine learning algorithm (e.g., a deep neural network (DNN) algorithm, a long short-term memory (LSTM) network algorithm, a gradient boosting algorithm, a K-means algorithm, and / or a random forest algorithm). Machine learning involves a computer learning from data to perform a task. As an example, a machine learning algorithm is used to train a machine learning model based at least in part on sample data referred to as "training data". Once trained, the machine learning model can be used to make predictions, decisions, or classifications related to new observations. In some aspects, the module 504 may be trained to predict signal metrics (e.g., signal to interference plus noise ratio (SINR) metrics and / or RSRP metrics). Alternatively or additionally, module 504 may be trained to predict TCI states, beams, and / or beam pairs (e.g., associated with a pair of TCI states or a TCI state and a spatial relationship, among other examples) based at least in part on signal metrics (e.g., UE-generated signal metrics and / or predicted signal metrics).

[0096] For illustration, the network node 502 may periodically receive UE reported signal metrics (e.g., from the UE 120), as shown in reference numerals 506, 508, and 510. As an example, the network node 502 may receive layer 1 RSRP (L1-RSRP) metrics and / or layer 1 SINR (L1-SINR) metrics from the UE 120 every 120 milliseconds (msec) as UE reported signal metrics. The module 504 may receive the UE reported signal metrics as input and predict one or more signal metrics and / or one or more TCI states at various time points, as shown in reference numerals 512-1 to 512-n (where n is an integer). For example, the module 504 may use the signal metrics reported by the UE shown in reference numeral 506 to predict a set of future signal metrics and / or TCI states with a period of 20 msec. The module 504 may iteratively receive the UE reported signal metrics as shown in reference numerals 508 and 510 as feedback for subsequent predictions. For illustration, module 504 may use the signal metric reported by the UE shown by reference numeral 508 and / or the signal metric reported by the UE shown by reference numeral 506 to predict the signal metric as shown by reference numeral 514-1 to reference numeral 514-n. Module 504 may alternatively or additionally select a TCI state and / or beam pair that is predicted to have better performance (e.g., improved signal quality, reduced recovery error, and / or increased data throughput) relative to other beams and / or TCI states. In order to save air interface resources, UE 120 may be configured to refrain from reporting signal metrics between configured reporting periods, as shown by reference numerals 506, 508, and 510.

[0097] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 Different from what is described.

[0098] In some networks, a network node may provide auxiliary information to a UE to identify a predicted network node transmit beam and / or associated TCI state (e.g., in order to better refine a UE receive (RX) beam). In some networks, a TCI indication and / or activation window may be reduced for future transmit beam scanning. For example, a network node may indicate and / or activate a future TCI state associated with a reference signal (RS) in order to receive scheduled physical downlink shared channel (PDSCH) communications from a preconfigured future TCI state output according to an AI model. However, in the absence of synchronization between the network node and the UE for the window when the TCI state predicted by the network node is valid, the network node may attempt to send subsequent communications before the UE is able to receive subsequent communications, which may result in communication errors that consume power, computation, network and / or power resources to detect and correct. Alternatively, when the UE is ready to receive subsequent communications, the network node may wait for an unnecessarily long amount of time to send subsequent communications, which may result in increased latency in communications.

[0099] In some aspects described herein, a UE may receive a MAC CE indication that activates a TCI state predicted by a network node. The UE may send an ACK associated with the MAC CE indication, and may receive a DCI indicating the TCI state predicted by the network node for subsequent communications. The DCI may schedule the subsequent communications at a scheduled time based at least in part on a threshold amount of time (e.g., a switching time) from the ACK or from the MAC CE indication. Additionally or alternatively, the DCI may schedule the subsequent communications at a scheduled time within (e.g., including or excluding) an additional threshold amount of time from the ACK or from the MAC CE indication.

[0100] In an example, when a MAC CE is received that activates a TCI state as a TCI state predicted by a network node (e.g., a future TCI state predicted by a network node), the UE may apply corresponding timeline rules to schedule and / or receive subsequent communications via the TCI state predicted by the network node using a TypeD-QCL source RS that is at least a CSI-RS or SSB. For example, for a first duration of X time slots after the time slot in which the UE sends an ACK for the MAC CE, the UE may not expect to schedule the PDSCH using the TCI state predicted by the network node. Assuming that the UE transmits an ACK for the MAC CE in time slot n, the UE may expect to schedule the PDSCH using the TCI state predicted by the network node during a second duration Y starting from time slot n+X+1 until time slot n+X+Y. In some aspects, if the UE is aware that the TCI state is a TCI state predicted by the network node, the value of X may be reduced.

[0101] In some aspects, the scheme may be applied based at least in part on the TCI state predicted by the network node not being in a previous active TCI state list (eg, indicated in a previous MAC CE) before the UE receives an activation MAC CE.

[0102] In some aspects, the scheme may reuse or extend parameters for an unknown TCI state switching delay timeline. For example, if the TCI state predicted by the network node is considered unknown (e.g., based on a definition in a communication protocol), the unknown TCI state switching delay may be reused or may be used as a basis for a value that may indicate X. In the example, the UE may not have yet identified the correct receive beam for the associated downlink RS, and the UE may require additional time to complete receive beam refinement. However, if the UE has reported the capability for receive beam prediction, the duration of X time slots may be shorter than the delay for the unknown TCI state.

[0103] In some aspects, the UE may report capabilities for values ​​of X. For example, for the case where the TCI state predicted by the network node is considered unknown, a minimum value of X may be reported by the UE as a capability. If the UE is additionally equipped with an AI / ML-based receive beam predictor (e.g., the input may be other DL-RS, associated L1-RSRP, and associated receive beam), the receive beam may be predicted by the UE and the minimum duration of X may be reduced (e.g., to 3msec for a known TCI state), even though the UE may not have measured the DL-RS for the indicated network node predicted TCI state.

[0104] In some aspects, the UE may receive an indication of the values ​​of X and / or Y via an activation MAC CE that activates the TCI state predicted by the network node. For example, the MAC CE may indicate the values ​​of X and / or Y for the TCI state predicted by each network node activated by the MAC CE. The scheme may be based at least in part on an index indicating the RRC configuration value of X and / or Y.

[0105] In some aspects, upon receiving a MAC CE activating at least one TCI state as a TCI state predicted by the network node (e.g., a "future TCI state predicted by the network node"), the UE may perform measurements of the RS and / or report measurements of the RS for a first duration X, or may not measure the RS for the first duration X. In a first example, based at least in part on the UE being able to predict a receive beam without further RS ​​measurements, or based at least in part on the UE having identified one or more suitable receive beams during a previous beam measurement for the TCI state predicted by the network node, the UE may not expect additional transmissions of a DL-RS associated with the TCI state predicted by the network node or a DL-RS associated with the TCI state predicted by the network node being a Type D quasi-co-located (QCL) DL-RS. In some aspects, the UE may not expect to receive the TCI state predicted by the network node during the first duration based at least in part on an implicit agreement between the network node and the UE, and without additional signaling to indicate the agreement. The implicit agreement may be based at least in part on the UE reporting to the network node an ability to predict receive beams without additional DL-RS measurements. Additionally or alternatively, the implicit agreement may be based at least in part on a DL-RS comprising a set of periodic (P) or semi-persistent (SP) channel measurement resources (CMRs) sent to the UE.

[0106] In some aspects, the UE may not expect to receive a TCI state predicted by a network node during the first duration based at least in part on the UE's explicit indication of whether such an additional DL-RS is requested during the first duration. The UE may send an explicit indication after receiving the MAC CE. For example, the UE may be expected to report a 2-bit ACK associated with the PDSCH carrying the TCI state activation MAC CE. A bit (e.g., the 2nd bit) may indicate whether such an additional DL-RS is requested during the first duration. In some aspects, the UE may expect at most one TCI state predicted by a network node to be activated by each MAC CE, and the explicit indication may indicate a request for an additional DL-RS for at most one TCI state predicted by a network node. In some aspects, if all network node predicted TCI states activated by the MAC CE do not require an additional DL-RS, the UE reports "no request"; otherwise, the UE reports a request for an additional DL-RS.

[0107] In some aspects, when the UE does not identify the correct receive beam during a previous beam measurement for a TCI state predicted by a network node, the UE cannot predict the receive beam. In some aspects, the UE expects to send an additional DL-RS associated with the TCI state (or a DL-RS of DL-RS TypeD-QCL with the TCI state) during a first duration. In some aspects, the UE may anticipate the transmission of the additional DL-RS based at least in part on an implicit agreement between the network node and the UE based at least in part on no additional signaling. For example, this may be based at least in part on the UE's failure to report to the network node that the UE supports receive beam prediction (e.g., an explicit indication of lack of support, or lack of an indication of support). In some aspects, the scheme may be based at least in part on a TCI state that is considered unknown. In some aspects, the type and / or configuration of the additional DL-RS may be determined based at least in part on the type and / or configuration of the RS specified for the unknown TCI state in the communication protocol.

[0108] In some aspects, the UE may anticipate the transmission of an additional DL-RS based at least in part on an explicit indication sent by the UE to the network node, the explicit indication indicating whether an additional DL-RS is requested during a first duration. The UE may send an explicit indication after receiving a TCI state activation MAC CE. For example, the UE may be expected to report a 2-bit ACK associated with the PDSCH carrying the TCI state activation MAC CE. One bit (e.g., the second bit) may indicate whether an additional DL-RS is requested during the first duration. In some aspects, the UE may expect at most one network node predicted TCI state to be activated by each MAC CE, and the explicit indication may indicate a request for additional DL-RS for at most one network node predicted TCI state. In some aspects, if the TCI states predicted by all network nodes activated by the MAC CE do not require additional DL-RS, the UE reports "no request", otherwise the UE reports a request for additional DL-RS.

[0109] In some aspects, the UE may be able to predict a receive beam, but still require a reduced number of additional DL-RS for a TCI state predicted by the network node. In some aspects, the UE may anticipate sending additional DL-RS associated with the TCI state (or DL-RS Type D-QCL with DL-RS associated with the TCI state) during a first duration based at least in part on an implicit agreement between the gNB and the UE, based on no additional signaling (e.g., based at least in part on a reported capability of the predicted receive beam, where the prediction still requests a certain amount of DL-RS measurements). In some aspects, the capability may indicate a number of repeated CSI-RS resources on a CSI-RS resource set requested for receive beam prediction for a TCI state predicted by the network node. In some aspects, the capability may indicate a number of P or SP CSI-RS or SSB opportunities requested for receive beam prediction for a TCI state predicted by the network node.

[0110] In some aspects, the UE may send an explicit indication of whether to request an additional DL-RS during a first duration (e.g., after receiving a TCI state activation MAC CE). For example, the UE may be expected to report a 2-bit ACK associated with the PDSCH carrying the TCI state activation MAC CE. One bit (e.g., the second bit) may indicate whether an additional DL-RS is requested during the first duration. In some aspects, the UE may expect that at most one network node predicted TCI state is activated by each MAC CE, and the explicit indication may indicate a request for an additional DL-RS for at most one network node predicted TCI state. In some aspects, if the TCI states predicted by all network nodes activated by the MAC CE do not require an additional DL-RS, the UE reports "no request", otherwise the UE reports a request for an additional DL-RS. If the second bit indicates a request for a DL-RS, the UE may expect to be triggered or activated with an SP or aperiodic (AP) CSI report to report the parameters of the DL-RS. In some aspects, if the UE has been scheduled with an uplink grant, the UE may expect to report the parameters of the DL-RS via a MAC CE. If the UE has not been scheduled with an uplink grant, the explicit indication may be an implicit scheduling request for reporting parameters of the DL-RS parameters. In some aspects, the DL-RS parameters include the number of repeated CSI-RS resources on the CSI-RS resource set requested for receive beam prediction for a TCI state predicted by the network node. In some aspects, the DL-RS parameters include the number of P or SP CSI-RS or SSB opportunities requested for receive beam prediction for a TCI state predicted by the network node (e.g., a "future TCI state").

[0111] In some aspects, the UE may support DCI-based indication of a TCI state predicted by a network node. In some aspects, the timeline of using the TCI state predicted by the network node based on DCI may be based at least in part on one or more parameters, a configuration of the UE, a reported capability of the UE, and / or a communication protocol.

[0112] In an example, the UE may report a time domain duration threshold (timeDurationForQCL_Predicted) for determining a receive spatial filter, wherein the time domain duration threshold is associated with a TCI state predicted by a network node indicated by a DL grant DCI for scheduling PDSCH. For example, if the indicated TCI state is unknown, but it has been identified as a TCI state predicted by a network node, then when the UE is configured with a higher layer parameter tci-PresentInDCI enabled for a control resource set (CORESET) for scheduling PDSCH at time slot n, the UE may support receiving PDSCH after a specific time. For example, the UE may support receiving a PDSCH associated with a TCI state predicted by a network node (e.g., a TCI state predicted by a network node of a serving cell in which a TCI state switch occurs) at the first time slot after time slot n+timeDurationForQCL_Predicted (e.g., a value X), where timeDurationForQCL_Predicted is a UE reporting capability for physical downlink control channel (PDCCH) processing, calculating and / or predicting a receive beam associated with a TCI state predicted by a network node, and applying a time domain duration threshold for spatial QCL information of a TCI state predicted by a network node.

[0113] In some aspects, the UE may expect a time offset between a DCI indicating a TCI state predicted by the network node and the first symbol of a PDSCH scheduled by a DL grant DCI to be greater than or equal to timeDurationForQCL_Predicted, where timeDurationForQCL_Predicted is a UE reported capability for calculating and / or predicting a duration threshold for a receive beam associated with a TCI state predicted by the network node (e.g., “future TCI state predicted by the gNB”).

[0114] In some networks, the UE may report a single capability timeDurationForQCL that defines the minimum number of OFDM symbols required for the UE to perform PDCCH reception and apply the spatial QCL information received in the DCI to PDSCH processing. The UE may indicate one value for the minimum number of OFDM symbols per subcarrier spacing for 60kHz and 120kHz. In some aspects, the UE should report another similar capability that is dedicated only to the TCI state predicted by the network node indicated by the DL grant DCI (e.g., the UE may also use the ML model to predict the receive beam without actually receiving beam scanning and / or measurements).

[0115] Based at least in part on the use of one or more of the techniques and / or configurations described herein, a UE and a network node may apply a duration (e.g., X) after receiving an indication of using a TCI state predicted by the network node, during which the UE does not support receiving communications via the TCI state predicted by the network node. The duration may be configured at least in part based on the capabilities of the UE, which may save power, computational, network, and / or communication resources to detect and correct the sending of communications before the UE is able to receive subsequent communications. Alternatively, configuring the duration based at least in part on the capabilities of the UE may reduce latency that may otherwise be caused by the network node waiting for an unnecessarily long amount of time to send communications when the UE is already ready to receive communications. Additionally or alternatively, based at least in part on synchronizing communications of an RS for the UE to obtain a UE receive beam associated with a TCI state predicted by the network node, the UE and the network node may reduce communication errors that may otherwise consume power, computational, network, and / or power resources to detect and correct.

[0116] Figure 6 600 is a diagram illustrating an example associated with predicting a network node TCI state according to the present disclosure. Figure 6 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in a Figure 6 The operations shown are performed after a wireless connection has been established.

[0117] As indicated by reference numeral 605, the network node may send configuration information, and the UE may receive the configuration information. In some aspects, the UE may receive the configuration information via one or more of RRC signaling, one or more MAC CEs, and / or DCI, etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for the UE to select (e.g., known to the UE and / or previously indicated by the network node or other network device) and / or explicit configuration information for the UE to configure the UE, etc.

[0118] In some aspects, the configuration information may indicate that the UE is to send capability information associated with switching to a TCI state predicted by the network node, predicting a receive beam with or without RS, and / or a time value associated with switching to a TCI state predicted by the network node.

[0119] The UE may configure itself based at least in part on the configuration information.In some aspects, the UE may be configured to perform one or more operations described herein based at least in part on the configuration information.

[0120] The UE may send a capability report and the network node may receive the capability report, as indicated by reference numeral 610. In some aspects, the capability report may indicate capabilities associated with switching to a TCI state predicted by the network node, predicting receive beams with or without an additional RS, and / or a time value associated with switching to a TCI state predicted by the network node, among other examples.

[0121] As shown in reference numeral 615, the UE may receive a MAC CE indication and the network node may send a MAC CE indication indicating activation of the TCI state predicted by the network node and / or indicating a time period for which the TCI state predicted by the network node is valid. In some aspects, the TCI state predicted by the network node may be unknown and / or may not be an active TCI state prior to receiving the MAC CE indication. In some aspects, the MAC CE may indicate that the TCI state predicted by the network node is predicted by the network node.

[0122] As shown in reference numeral 620, the UE may send and the network node may receive an ACK for the MAC CE indication, an indication of whether to request an additional RS, and / or an indication of the requested RS. In some aspects, the ACK may include an indication (e.g., a single-bit indication) of whether to request an additional RS. In some aspects, the indication of whether to request an additional RS is associated with a TCI state predicted by a single network node activated by the MAC CE. In some aspects, the indication of whether to request an additional RS is associated with a TCI state predicted by all network nodes activated by the MAC CE.

[0123] As indicated by reference numeral 625, the UE may receive and the network node may send an RS associated with the TCI state predicted by the network node. In some aspects, the UE may receive the RS based at least in part on an indication of resources for receiving the RS. For example, the network node may send an indication of resources based at least in part on receiving an ACK.

[0124] In some aspects, the UE may receive a standard number of RSs (e.g., associated with an unknown TCI state) or a reduced number of RSs. The number of RSs may be explicitly indicated by the UE after receiving the MAC CE, or may be based at least in part on previously indicated capabilities of the UE, among other examples. For example, the number of RSs may be reduced based at least in part on a reported ability of the UE to perform beam prediction for a UE receive beam. In some aspects, the number of RSs may be based at least in part on a TCI state where the TCI state predicted by the network node is an unknown TCI state (e.g., not configured for activation by RRC signaling and / or not activated by a previous MAC CE).

[0125] In some aspects, the UE may not receive any RS. For example, the UE may not receive RS between the reception of the MAC CE indication and the reception of the DCI that schedules subsequent communications using the TCI state predicted by the network node. The UE may not receive RS based at least in part on an explicit indication that RS is not requested (e.g., within the ACK described in conjunction with reference numeral 620) and / or based at least in part on reported UE capabilities (e.g., associated with a UE prediction of a UE receive beam without RS).

[0126] As indicated by reference numeral 630, the UE may receive, and the network node may send, DCI indicating the network node predicted TCI state for subsequent communications. In some aspects, the DCI may schedule subsequent communications at a scheduled time based at least in part on a threshold amount of time from an ACK or from a MAC CE indication.

[0127] In some aspects, the threshold amount of time (e.g., a minimum time and / or X) is based at least in part on an unknown TCI state switching latency, the UE's capability for receive beam prediction, an indication of the threshold amount of time by the UE, or an indication of the threshold amount of time (e.g., within a MAC CE indication).

[0128] In some aspects, the DCI schedules subsequent communications based further at least in part on a scheduled time within an additional threshold amount of time (e.g., X+Y) from the ACK or from the MAC CE indication. In some aspects, the first threshold amount of time and / or the second threshold amount of time is based at least in part on an unknown TCI state switching latency, a capability of the UE for receive beam prediction, an indication by the UE of one or more of the first threshold amount of time or the second threshold amount of time, and / or an indication within the MAC CE indication of one or more of the first threshold amount of time or the second threshold amount of time, as well as other examples.

[0129] As indicated by reference numeral 635, the UE and the network node may communicate subsequent communications at a time when the TCI state predicted by the network node is valid. For example, the TCI state predicted by the network node may be valid based at least in part on a time between a first threshold amount of time and a second threshold amount of time from receipt of a MAC CE or from transmission of an ACK.

[0130] In some aspects, the UE may receive the subsequent communication without receiving a reference signal associated with the TCI state predicted by the network node between the first time of receiving the MAC CE indication and the second time of receiving the subsequent communication. In some aspects, receiving the subsequent communication without receiving a reference signal associated with the TCI state predicted by the network node between the first time of receiving the MAC CE indication and the second time of receiving the subsequent communication is based at least in part on: an indication by the UE of support for predicted receive beams without additional reference signal measurements, a downlink reference signal associated with the TCI state predicted by the network node being associated with a periodic or semi-persistent channel measurement resource, and / or an indication by the UE and within feedback associated with the MAC CE that the reference signal was not requested, among other examples. In some aspects, the indication within the feedback associated with the MAC CE is associated with the TCI state predicted by the network node based at least in part on being the only network node predicted TCI state indicated in the MAC CE indication, or is associated with the TCI state predicted by the network node based at least in part on being associated with all network node predicted TCI states indicated in the MAC CE indication.

[0131] Based at least in part on the use of one or more of the techniques and / or configurations described herein, a UE and a network node may apply a duration (e.g., X) after receiving an indication of using a TCI state predicted by the network node, during which the UE does not support receiving communications via the TCI state predicted by the network node. The duration may be configured at least in part based on the capabilities of the UE, which may save power, computational, network, and / or power resources to detect and correct the sending of communications before the UE is able to receive subsequent communications. Alternatively, configuring the duration based at least in part on the capabilities of the UE may reduce latency that may otherwise be caused by the network node waiting for an unnecessarily long amount of time to send communications when the UE is already ready to receive communications. Additionally or alternatively, based at least in part on synchronizing communications of an RS for the UE to obtain a UE receive beam associated with a TCI state predicted by the network node, the UE and the network node may reduce communication errors that may otherwise consume power, computational, network, and / or power resources to detect and correct.

[0132] As indicated above, Figure 6 are provided as examples. Other examples can be found in the Figure 6 Different from what is described.

[0133] Figure 7 is a diagram illustrating an example 700 associated with predicting a network node TCI state according to the present disclosure. Figure 7 In the context of , a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in Figure 7 The operations shown are performed after a wireless connection has been established.

[0134] like Figure 7 As shown, the UE may receive a MAC CE activating a TCI state predicted by the network node 705. In some aspects, the TCI state predicted by the network node may be an unknown TCI state (eg, the UE does not have valid RS measurements).

[0135] The UE may send an ACK for the MAC CE 710 during time slot n. As described herein, the ACK may indicate a request for the RS or may deny the RS to use the TCI state predicted by the network node. During a first duration (X) 715 extending to time slot n+X+1, the UE does not expect to receive communications using the TCI predicted by the network node. In some aspects, the UE may receive an RS for the TCI predicted by the network node during the first duration (X) 715 for the UE to measure and obtain a UE receive beam for communicating via the TCI predicted by the network node.

[0136] After the first duration (X) 715, the UE may receive DCI indicating a network node predicted TCI state 720 for transmission of subsequent communications. The UE may receive PDSCH communications using the network node predicted TCI 725 during a second duration (Y) 730 extending from the first duration (X) 715. In some aspects, the UE may be configured to receive DCI and / or PDSCH communications via the network node predicted TCI state only during the second duration (Y) 730.

[0137] As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 Different from what is described.

[0138] Figure 8 8 is a diagram illustrating an example 800 associated with predicting a network node TCI state according to the present disclosure. Figure 8 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in a Figure 8 The operations shown are performed after a wireless connection has been established.

[0139] As indicated by reference numeral 805, the network node may send configuration information, and the UE may receive the configuration information. In some aspects, the UE may receive the configuration information via one or more of RRC signaling, one or more MAC CEs, and / or DCI, etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for the UE to select (e.g., known to the UE and / or previously indicated by the network node or other network device) and / or explicit configuration information for the UE to configure the UE, etc.

[0140] In some aspects, the configuration information may indicate that the UE is to send a DCI-based indication of a TCI state predicted by a receiving network node, capability information associated with predicting a receive beam with or without an additional RS, and / or a time value associated with switching to a TCI state predicted by the network node. In some aspects, the configuration information enables a DCI-based indication of a TCI state predicted by a network node.

[0141] The UE may configure itself based at least in part on the configuration information.In some aspects, the UE may be configured to perform one or more operations described herein based at least in part on the configuration information.

[0142] As shown by reference numeral 810, the UE may send a capability report and the network node may receive the capability report. In some aspects, the capability report may indicate a DCI-based indication of a TCI state predicted by the receiving network node, a capability associated with predicting a receive beam with or without an additional RS, and / or a time value associated with switching to a TCI state predicted by the network node, as well as other examples. In some aspects, the UE may send an indication of support for receiving a DCI-based indication of a TCI state predicted by the network node and / or one or more parameters associated with the support (e.g., restrictions on the support). For example, the UE may indicate a threshold amount of time (e.g., minimum time) between the reception of the DCI-based indication and the reception of the communication of the TCI state predicted by the network node. In some aspects, the threshold amount of time is based at least in part on the ability of the UE to configure a receive beam for the TCI state predicted by the network node. In some aspects, the threshold amount of time is whether the subcarrier spacing associated with the communication or the TCI state predicted by the network node is unknown, as well as other examples.

[0143] As shown by reference numeral 815, the UE may receive a DCI indication indicating a TCI state predicted by the network node for subsequent communications and / or indicating a time period for which the TCI state predicted by the network node is valid. In some aspects, the time period may be valid based at least in part on after a first threshold amount of time (e.g., X) and / or before a second threshold amount of time (e.g., X+Y).

[0144] In some aspects, the UE may receive an indication within the DCI or outside the DCI that the unknown TCI state is the TCI state predicted by the network node and / or that the TCI state predicted by the network node is predicted by the network node. For example, the UE may receive RRC signaling (e.g., associated with a TCI state configured for activation), MAC signaling (e.g., associated with activating a configured TCI state), or within the DCI that the network node predicted is the network node predicted. In some aspects, the MAC CE is configured to activate only the TCI state predicted by the network node (e.g., a dedicated MAC CE for the TCI state predicted by the network node).

[0145] As shown by reference numeral 820, the UE and the network node may communicate subsequent communications at a time when the TCI state predicted by the network node is valid. In some aspects, the time when the TCI state predicted by the network node is valid is based at least in part on a first threshold amount of time (e.g., a minimum time) and / or a second threshold amount of time (e.g., a maximum time). In some aspects, the UE and the network node may continue to use the TCI predicted by the network node after the time based at least in part on performing additional beam management.

[0146] As indicated above, Figure 8are provided as examples. Other examples can be found in the Figure 8 Different than described.
