Description

Technical Field

[0001] The following relates to wireless communications, including antenna position configuration for predictive beam management. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, and the like. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communications for communication devices, which may be referred to as user equipment (UE). Summary of the invention

For example, a user equipment (UE) may receive an indication or configuration of a beamforming codebook associated with a serving cell of a network entity, and the beamforming codebook may indicate antenna positions and spatial information of channel resources associated with the beamforming codebook.

For example, the UE may identify, select, or otherwise determine the association between the first channel resource and the second channel resource based on the corresponding antenna positions of the first channel resource in the first set of channel resources and the second channel resource in the second set of channel resources. Therefore, the UE may predict the signal strength of the second channel resource based on the channel measurement result of the first channel resource, and in some specific implementations, the predicted signal strength of the second channel resource may be included in a channel state information (CSI) report.

[0052] In some systems, a user equipment (UE) may use a model such as an artificial intelligence (AI) or machine learning (ML) model to predict information associated with a first set of beams based on a set of measurement results of a second set of beams. For example, the UE may receive information associated with a first set of beams (referred to herein as set A) and a second set of beams (referred to herein as set B). Based on the received information, the UE may use the signal strength measurement results of the set B beams to predict the signal strength measurement results of the set A beams. In some aspects, the UE may receive an indication of a connection regarding the respective beam shapes of the set A beams and the set B beams, and may use this connection to assist in predicting the signal strength of the set A beams. If each beam in the set A beams and the set B beams is associated with the same antenna point position, the connection between the set A beams and the set B beams based on the respective beam shapes may be sufficient (e.g., facilitating a sufficiently accurate prediction of the set A beams).

[0053] However, as the antenna array size increases, the network entity may use different sub-arrays (which may be farther away from each other) or different boresight departure points for different beams. As a result, the relative antenna position (e.g., the boresight departure position) may affect which connections between the set A beam and the set B beam are appropriate, and may also affect the signal strength prediction at the UE. For example, if the set A beam and the set B beam have the same beam shape but are associated with boresight departure positions that are relatively far away from each other, using the set B beam to predict the signal strength of the set A beam may result in inaccurate signal strength predictions. However, some systems may lack a mechanism by which the network entity can efficiently signal the antenna positions of the set A beam and the set B beam to the UE, so that the UE can use the antenna position to identify or ascertain the connection between the set A beam and the set B beam and make corresponding signal strength predictions for the set A beam.

[0054] In some specific implementations, the UE and the network entity may support a beamforming codebook configuration, according to which the network entity may include, for each codepoint of the beamforming codebook, an indication of the antenna position and spatial information associated with the channel resources corresponding to the codepoint. In some aspects, the beamforming codebook may be specific to or associated with a serving cell of the network entity. Similarly, the antenna position indicated by the beamforming codebook may be associated with a position on an antenna panel of the network entity associated with the serving cell. In addition, the beamforming codebook may include antenna positions and spatial information for channel resources associated with beam measurement (which may be associated with set B beams) and channel resources associated with beam prediction (which may be associated with set A beams).

[0055] Thus, the UE may identify, select, ascertain, or otherwise determine the connection or association regarding the set A beam and the set B beam based on the corresponding antenna position together with the corresponding spatial information (e.g., the corresponding beam shape), and the UE may predict the signal strength of one or more set A beams (e.g., one or more channel resources associated with the beam prediction) based on these connections or associations. In some aspects, the UE may send a channel state information (CSI) report including the predicted signal strength of one or more set A beams. In some specific implementations, the UE may also use the connection or association to generate a CSI report. For example, the UE may include the predicted signal strength of the set A beam connected to or associated with the set B beam having the maximum measured signal strength, and may exclude the predicted signal strength of the set A beam that is not connected to or associated with the set B beam having the maximum measured signal strength.

[0056] Specific implementations of the subject matter described in the present disclosure may be implemented to achieve one or more of the following potential advantages. For example, by supporting a beamforming codebook that enables the UE to predict and report signal strength based on its corresponding antenna position between set A beams and set B beams, the UE may achieve lower signaling overhead and reduced measurement-related power consumption costs. In other words, enabling beam prediction for deployments where a network entity uses a relatively large antenna array (e.g., a deployment where the network entity operates multiple subarrays) may reduce the amount of reference signals that the network entity expects to send, and may reduce the amount of resources via which the UE monitors and measures signal strength. In addition, the UE and the network entity may support one or more mutually understood or signaled rules associated with the amount of predicted signal strength that the UE may include in a CSI report based on the described antenna position-based connection or association between set A beams and set B beams. In addition, supporting beam prediction processes across different deployments (including deployments where network entities use relatively large antenna arrays) can promote wider adoption of one or both of AI-based beam prediction or ML-based beam prediction and larger antenna array configurations, thereby improving connectivity and reducing latency. Thus, UEs and network entities can employ the described techniques in a variety of scenarios including beam management processes, and can experience higher data rates, greater capacity, and higher spectral efficiency.

[0057] Various aspects of the present disclosure are first described in the context of a wireless communication system. Various aspects of the present disclosure are additionally illustrated by signaling diagrams, beamforming codebook configurations, and process flows related to antenna position configurations for predictive beam management. Various aspects of the present disclosure are further illustrated and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to antenna position configurations for predictive beam management.

[0058] Figure 1 An example of a wireless communication system 100 supporting antenna position configuration for predictive beam management according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.

[0059] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other names. In some examples, the network entities 105 and the UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs). Components within a wireless communication system may be coupled to each other (e.g., operationally coupled, communicatively coupled, functionally coupled, electronically coupled, and / or electrically coupled).

[0060] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile or both stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1 . The UEs 115 described herein may be capable of supporting communication with various types of devices (such as other UEs 115 or network entities 105), such as Figure 1 shown.

[0061] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, reference to UE 115, network entity 105, apparatus, device, or computing system may include disclosure that UE 115, network entity 105, apparatus, device, or computing system is a node. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0062] In some examples, the network entities 105 may communicate with the core network 130, or communicate with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3 or other interface protocols). In some examples, the network entities 105 may communicate with each other via the backhaul communication link 120 (e.g., according to X2, Xn or other interface protocols) directly (e.g., directly between each network entity 105) or indirectly (e.g., via the core network 130). In some examples, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0063] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next-generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next-generation eNB (ng-eNB), a Home Node B, a Home Evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0064] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0065] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DUs 165 and the RUs 170, such that the DUs 165 may support one or more layers of the protocol stack, and the RUs 170 may support one or more different layers of the protocol stack. The DUs 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities 105 that communicate via such communication links.

[0066] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled IAB donor's DU 165. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0067] Where the techniques described herein are applied to the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support antenna position configuration for predictive beam management as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0068] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other appropriate terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client. UE 115 may also include or be referred to as a personal electronic device, such as: a cellular phone, a personal digital assistant (PDA), a multimedia / entertainment device (e.g., a radio, an MP3 player, or a video device), a camera, a gaming device, a navigation / positioning device (e.g., a GNSS (Global Navigation Satellite System) device based on, for example, GPS (Global Positioning System), Beidou, GLONASS or Galileo, ground-based equipment, etc.), a tablet computer, a laptop computer, a netbook, a smartbook, a personal computer, a smart device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, virtual reality goggles, a smart wristband, smart jewelry (e.g., a smart ring, a smart bracelet)), a drone, a robot / robotic device, a vehicle, an in-vehicle device, a meter (e.g., a parking meter, an electric meter, a gas meter, a water meter), a monitor, a gas pump, an appliance (e.g., a kitchen appliance, a washing machine, a dryer), a location tag, a medical / health care device, an implant, a sensor / actuator, a display, or any other suitable device or personal computer configured to communicate via a wireless or wired medium. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, which may be implemented in various objects such as appliances or vehicles or meters.

[0069] In one aspect, the techniques disclosed herein may be applicable to MTC or IoT UEs. MTC or IoT UEs may include MTC / enhanced MTC (eMTC, also known as CAT-M, Cat M1) UEs, NB-IoT (also known as CAT NB1) UEs, and other types of UEs. eMTC and NB-IoT may refer to future technologies that may evolve from or be based on these technologies. For example, eMTC may include FeMTC (further eMTC), eFeMTC (further enhanced eMTC), mMTC (massive MTC), and NB-IoT may include eNB-IoT (enhanced NB-IoT) and FeNB-IoT (further enhanced NB-IoT). The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115 that may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, relay base stations, such as Figure 1 shown.

[0070] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any part (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send", "receive", or "communicate" when referring to the network entity 105 may refer to any part of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0071] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system employing MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The amount of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that a relatively high amount of resource elements (e.g., in the transmission duration) and a relatively high order of the modulation scheme may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0072] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period T s =1 / (Δfmax ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0073] Each frame may include a plurality of consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, a frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro-time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0074] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the amount of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).

[0075] According to various techniques, physical channels may be multiplexed using carriers for communication. Physical control channels and physical data channels may be multiplexed for signaling via downlink carriers, for example, using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0076] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0077] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms "ultra-reliable", "low latency" and "ultra-reliable low latency" are used interchangeably herein.

[0078] In some examples, a UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured by the network entity 105 (e.g., scheduled by the network entity). In some examples, one or more UEs 115 in such a group may be outside the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.

[0079] The core network 130 may provide user authentication, access authentication, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access layer (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered via a user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0080] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than communications using smaller frequencies and longer wavelengths in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0081] The wireless communication system 100 may also operate using a super high frequency (SHF) region (also known as a centimeter band) that may be in the range of 3 GHz to 30 GHz or an extremely high frequency (EHF) region (e.g., 30 GHz to 300 GHz) (also known as a millimeter band) using a spectrum. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and network entity 105 (e.g., base station 140, RU 170), and the EHF antenna of the corresponding device may be smaller and closer than the UHF antenna. In some examples, such technology may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by greater attenuation and shorter range than SHF or UHF transmissions. The technology disclosed herein may be adopted across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.

[0082] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology using unlicensed bands, such as the 5 GHz Industrial, Scientific, and Medical (ISM) band. When operating using unlicensed RF spectrum bands, devices such as the network entity 105 and the UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions.

[0083] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly (such as an antenna tower). In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of antenna ports of multiple rows and columns that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0084] The network entity 105 or UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technologies include: single-user MIMO (SU-MIMO), in which multiple spatial layers are sent to the same receiving device; and multi-user MIMO (MU-MIMO), in which multiple spatial layers are sent to multiple devices.

[0085] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a sender device or a receiver device (e.g., network entity 105, UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the sender device and the receiver device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the sender device or the receiver device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the sender device or the receiver device or relative to some other orientation).

[0086] The network entity 105 or UE 115 may use beam scanning techniques as part of a beamforming operation. For example, the network entity 105 (e.g., base station 140, RU 170) may use multiple antennas or antenna arrays (e.g., antenna panels) to perform beamforming operations for directional communication with UE 115. Some signals (e.g., synchronization signals, reference signals, beam selection signals, or other control signals) may be sent multiple times by the network entity 105 along different directions. For example, the network entity 105 may send signals according to different sets of beamforming weights associated with different transmission directions. Transmission along different beam directions may be used to identify (e.g., by a transmitting device (such as network entity 105), or by a receiving device (such as UE 115)) the beam direction for later transmission or reception by the network entity 105.

[0087] Some signals, such as data signals associated with a particular receiving device, may be sent by a sending device (e.g., a sending network entity 105, a sending UE 115) along a single beam direction (e.g., a direction associated with a receiving device (such as a receiving network entity 105 or a receiving UE 115)). In some examples, a beam direction associated with the transmission along a single beam direction may be determined based on signals sent along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions, and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0088] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured set of beams across a system bandwidth or one or more subbands. Network entity 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may or may not be precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-panel codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0089] A receiving device (e.g., UE 115) may perform receiving operations according to multiple receiving configurations (e.g., directional listening) when receiving various signals (such as synchronization signals, reference signals, beam selection signals, or other control signals) from a receiving device (e.g., network entity 105). For example, the receiving device may perform reception according to multiple receiving directions by: receiving via different antenna subarrays, processing the received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing the received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0090] In some aspects, the wireless communication system 100 may support one or more beam management techniques. For example, the UE 115 may be in an RRC idle state (e.g., RRC_IDLE) or an RRC inactive state (e.g., RRC_INACTIVE), and may send or receive one or more tracking reference signals (TRS) prior to initial access. As part of the initial access, one or more devices (e.g., one or both of the UE 115 and the network entity 105) may perform synchronization signal block (SSB) beam scanning, which may be associated with wide beam scanning. In some aspects, the initial access may involve a contention-based random access (CBRA) process or a contention-free random access (CFRA) process associated with the transmission or reception of a random access channel (RACH) opportunity (RO) or a preamble, or the transmission or reception of an SSB.

[0091] When a beam pair is established between two devices (e.g., between UE 115 and network entity 105), each device may perform beam management in an RRC connected state (e.g., RRC_CONNECTED). In some aspects, the beam management may include sending or receiving one or more SSBs, one or more CSI reference signals (CSI-RS) or one or more sounding reference signals (SRS), layer 1 (L1) reference signal received power (RSRP) reporting, and transmission configuration indicator (TCI) state configuration or indication. In some aspects, beam management (e.g., SSB or CSI-RS associated beam management) may be associated with a set of processes P1, P2, and P3 designed for beam management when the device is in a connected state. P1 may be associated with beam selection (e.g., the network entity 105 may scan beams, and the UE 115 may select one of the beams and report the selected beam to the network entity 105); P2 may be associated with beam refinement for the transmitter (e.g., the network entity 105 may refine the beam by scanning a narrower beam across a narrower range, and the UE 115 may select a narrower one of the narrower beams and report the selected narrower beam to the network entity 105); and P3 may be associated with beam refinement for the receiver (e.g., the network entity 105 may fix the beam, and the UE 115 may refine its receive beam). In some aspects, beam management (e.g., SRS-associated beam management) may be associated with a set of different uplink beam management processes U1, U2, and U3, each of which may be associated with beam scanning.

[0092] Additionally or alternatively, beam management may include L1 signal to interference plus noise ratio (SINR) reporting and overhead and latency reduction. In some aspects, overhead and latency reduction may be associated with or otherwise relate to one or more component carrier (CC) group beam updates and lower latency uplink beam updates. Furthermore, in some aspects, beam management may involve beam measurements or reporting, or both, associated with unified TCI states and L1 or layer 2 (L2) center mobility. For example, the beam management process may include dynamic TCI state updates, uplink multi-panel selection, maximum permissible exposure (MPE) mitigation, or other techniques that facilitate further beam management latency reduction. Furthermore, some beam management processes may include processes associated with high speed train (HST) deployment, single frequency network (SFN) deployment, or multi-TRP deployment, or any combination thereof.

[0093] In some aspects, a device may measure, identify, or otherwise experience beam failure detection (BFD) based on measurements associated with beam management, and may perform one or more beam failure recovery procedures. BFD and beam failure recovery (BFR) may be performed for a primary cell (PCell), a primary secondary cell (PSCell), or a secondary cell (SCell). In addition, BFD and BFR may involve sending or receiving one or more BFD reference signals (BFD-RS), physical downlink control channel (PDCCH) block error rate (BLER) measurements, link recovery requests via scheduling requests (SRs), or MAC-CE-based BFR for SCells, or any combination thereof. In some cases, such as when a device cannot recover a failed beam pair link, the device may declare a radio link failure (RLF) and attempt to reestablish a connection via one or more initial establishment procedures.

[0094] Various devices of the wireless communication system 100 may support one or more AI or ML models associated with air interface predictions (e.g., predictions associated with wireless communications). In some deployments, for example, the devices may utilize or use AI or ML models for CSI feedback enhancement (e.g., for achieving overhead reduction, higher accuracy, and more accurate predictions), beam management (e.g., beam prediction in the time domain or spatial domain for overhead and latency reduction and for higher beam selection accuracy), or positioning accuracy enhancement for different scenarios (e.g., scenarios associated with severe non-line-of-sight (NLOS) conditions).

[0095] In some cases, the device may utilize or use an AI or ML model for a specific use case such that the AI ​​or ML model approach is sufficiently diverse to support constraints on various levels of collaboration between the UE 115 and the network entity 105. In addition, various devices may support one or both of the AI ​​or ML model or description to identify common and specific characteristics for framework investigation or decision making. For example, the device may support models and descriptions for characterizing lifecycle management of AI or ML models, such as aspects related to model training, model deployment, model inference, model monitoring, or model updates.

[0096] In some deployments, the UE 115 or the network entity 105 may use AI-based predictive beam management or ML-based predictive beam management (e.g., for Uu beam management). For example, other beam management techniques may involve identifying beam quality or failure via measurement results, which may be associated with greater power or overhead to achieve suitable performance. In addition, due to constraints on power or overhead, beam management based on measurement results may be associated with limited accuracy, and latency and throughput may be adversely affected by beam recovery work. On the other hand, predictive beam management may be associated with reduced power or overhead, higher accuracy, lower latency, or higher throughput. For example, a predictive beam management process may enable a device to predict unmeasured beam quality (which may be associated with lower power consumption, lower overhead, or greater beam selection accuracy) and predict future beam obstruction or failure (which may be associated with lower latency and greater throughput). Such predictive beam management may involve predictions in the spatial domain, time domain, frequency domain, or any combination thereof.

[0097] Some devices may specifically employ AI or ML to compensate for or address the problem that beam prediction may be highly nonlinear in some deployments. For example, predicting future transmit beam quality may depend on the speed or trajectory of UE 115, one or more receive beams to be used, or interference, which may be difficult to model via some statistical signaling processing methods (e.g., non-AI-based statistical processing methods or non-ML-based statistical processing methods). In some deployments, there may be a tradeoff between performance and UE power consumption based on whether beam prediction is performed at UE 115 or at network entity 105. For example, to predict future downlink transmit beam quality, UE 115 may have more observations (e.g., via measurements) than network entity 105 (e.g., via UE feedback messages), so that beam prediction at UE 115 may outperform beam prediction at network entity 105 (at the expense of consuming more UE power for prediction or inference processing tasks). In addition, model training may be performed at UE 115 or network entity 105, and the decision between training locations may be associated with work on data collection versus work on UE computation. For example, if the training is performed by the network entity 105, the data may be collected via an air interface or via an application layer approach. If the training is performed by the UE 115, the UE 115 may perform additional UE computation or buffering tasks for the model training and associated data storage.

[0098] AI-based spatial or time domain beam prediction or selection or ML-based spatial or time domain beam prediction or selection (e.g., for downlink) may involve one or more of the various processes. For example, AI-based spatial or time domain beam prediction or selection or ML-based spatial or time domain beam prediction or selection may be used for initial access, secondary cell group (SCG) setup, service beam refinement, link quality and interference adaptation (e.g., one or more parameters, such as channel quality indicator (CQI) or precoding matrix indicator (PMI)), beam failure or occlusion prediction, or RLF prediction. In some aspects, specific one or more selection or prediction schemes may be used for each of such various processes. For example, codebook-based spatial domain selection may be used for initial access, SCG setup, service beam refinement, or link quality and interference adaptation. Non-codebook-based spatial domain prediction may be used for service beam refinement and link quality and interference adaptation. Additionally or alternatively, joint spatial and time domain beam prediction may be used for serving beam refinement, link quality and interference adaptation, beam failure or obstruction prediction, or RLF failure prediction.

[0099] The codebook-based spatial selection may be associated with an input of a first set of beams (e.g., measurement results of the first set of beams) and a predicted output (e.g., an output of an AI or ML model) of a second set of beams (e.g., a predicted set of beams). For interference at the network entity 105, the input may be associated with or include UE feedback and assistance information (e.g., history or location information). For inference at the UE 115, the input may be associated with or include UE measurement results and assistance information (e.g., location information). The UE 115 may report or measure such measurement information using spatial or time domain compressed beam measurements. The codebook-based spatial selection may be associated with fewer beam measurements, which may result in reduced power at the measuring device (e.g., UE 115).

[0100] Non-codebook based spatial prediction may be associated with an input of a channel set or beam set (e.g., measurement results associated with the channel set or beam set) and an output of a point direction, angle of departure (AoD), or angle of arrival (AoA). For inference at the network entity 105, the input may be associated with or include UE feedback and assistance information (e.g., history or location information). For inference at the UE 115, the input may be associated with or include UE measurement results and assistance information (e.g., location information). Such reporting or measurement of such measurement information at the UE 115 may be facilitated via raw channel extraction. Non-codebook based spatial prediction may be associated with higher beam management accuracy without excessive beam scanning.

[0101] From spatial to spatial plus temporal, joint spatial and temporal beam prediction may be associated with a time series input and output associated with both codebook-based spatial and temporal beam prediction and non-codebook-based spatial and temporal point direction, AoD, or AoA prediction. The time series input may include UE reports or measurements at a first time or measurement occasion (e.g., measurement occasion #0) to an Nth time or measurement occasion (e.g., measurement occasion #1). th UE reports or measurements at a time or measurement occasion (e.g., measurement occasion #N). Based on the joint spatial and temporal beam prediction, the time series input may be input to a first AI or ML model to obtain a first output of codebook-based spatial and temporal beam prediction, and may be input to a second AI or ML model to obtain a second output of non-codebook-based spatial and temporal point direction, AoD or AoA prediction.

[0102] The prediction performance or cost may depend on whether the prediction is performed by the UE 115 or the network entity 105. If the prediction is performed at the network entity 105, the network entity 105 may use relatively more powerful computing power (e.g., compared to the UE 115), access to the distribution of L1 reports in terms of history and location, access to feedback or locations of other UEs 115, knowledge of transmit beam shape and pointing direction to assist in beam prediction. In some deployments, the prediction performance at the network entity 105 may be balanced with other factors, such as only the strongest beam or beams may be reported by the UE 115, it may be difficult to know the receive beams used to derive L1 or CSI feedback, (all) UE feedback is quantized (and may potentially be missed), and it may be difficult to know the orientation or rotation state of the UE 115. If beam prediction is performed at the UE 115, the UE 115 may use access to instantaneous and filtered measurements of a set of (e.g., all) beams, access to receive beams used to derive the measurements, raw or unquantized (all) measurements, and (at least partially) knowledge of or the ability to predict its own orientation and rotation to assist in beam prediction. In some deployments, the prediction performance at the UE 115 may be balanced with other factors, such as the UE 115 may have relatively limited computational power, relatively limited knowledge of the historical distribution of L1 reports in the cell, limited access to L1 or CSI feedback from other UEs 115, or relatively limited indication or awareness of transmit beam shape or pointing direction. In some aspects, the UE 115 may send assistance information to assist in beam prediction configuration.

[0103] In some deployments, for AI-based beam management or ML-based beam management, devices of the wireless communication system 100 may support one or more beam management cases for characterization and benchmark performance evaluation. A first beam management case or BM-Case 1 may be associated with spatial downlink beam prediction for a set of beams A based on measurement results of a set of beams B. A second beam management case or BM-Case 2 may be associated with temporal downlink beam prediction for a set of beams A based on historical (e.g., previous) measurement results of a set of beams B. For use cases of BM-Case 1 or BM-Case 2 or both, the UE 115 or the network entity 105 may support downlink transmit beam prediction, downlink receive beam prediction, or beam pair prediction (wherein a beam pair may include a downlink transmit beam and a corresponding downlink receive beam).

[0104] The beams of set A and set B may be in the same frequency range or in different frequency ranges. In some aspects, set B may be a subset of set A, wherein the number of beams in set A and set B may vary. In some other aspects, set A and set B may be the same. In some other aspects, set A and set B may be different. For example, set A may include a set of relatively narrow beams, and set B may include a set of relatively wide beams. In such aspects, the number of beams in set A and set B may vary, and there may be a defined quasi-co-location (QCL) relationship between the beams in set A and the beams in set B. In addition, various types or specific implementations of codebook constructions of set A and set B may be used without exceeding the scope of the present disclosure. In the context of such a set A of beams and a set B of beams, set A may be used for downlink beam prediction, and set B may be used for downlink beam measurement.

[0105] The UE 115 may receive control signaling from the network entity 105 that indicates, configures, activates, or triggers CSI reporting from the UE 115. For example, the UE 115 may be configured to send one or more synchronization signal (SS) / physical broadcast channel (PBCH) resource indicators (SSBRI) or CSI-RS resource indicators (CRI) and L1-RSRP or L1-SINR reports via one or more CSI reports. In some deployments, the UE 115 may receive (e.g., may be configured with) ReportQuantity=ssb-Index-RSRP, ssb-Index-SINR, cri-RSRP, or cri-SINR for joint SSBRI / CRI and L1-RSRP / L1-SINR beam reporting. UE 115 may report (eg, send) nrofReportedRS parameters (which may be RRC configured and may be up to 2 or 4 depending on UE capabilities) that may be different for the SSBRI or CRI of each CSI-ReportConfig.

[0106] For L1-RSRP reporting, for the strongest SSBRI / CRI, RSRP may be reported in the range of [-140, -44] dBm using 7 bits with a step size of 1 dBm. For the remaining SSBRI / CRI, differential RSRP (e.g., the maximum RSRP reported in absolute or full value via 7 bits) may be reported in the range of [0, -30] dB using 4 bits with a step size of 2 dB and with reference to the L1-RSRP of the strongest SSBRI / CRI. For the L1-RSRP of the strongest SSBRI / CRI, the RSRP may be reported in the range of [0, -30] dB using 4 bits with a step size of 2 dB. 7= 128 but 140 - 44 + 1 = 97, there may be one or more invalid code points. In some systems, the mapping between the reported 7-bit code points and 4-bit code points and the actual measured RSRP values ​​may be defined by a specification (such as a network specification).

[0107] Similarly, for L1-SINR reporting, for the strongest SSBRI / CRI, 7 bits may be used to report SINR in the range of [-23,40] dB with a step size of 0.5 dB. For the remaining SSBRI / CRI, 4 bits may be used to report differential SINR (e.g., the maximum SINR reported in absolute or complete value via 7 bits) in the range of [0,-15] dB with a step size of 1 dB and reference to the L1-SINR of the strongest SSBRI / CRI. For the strongest and remaining SSBRI / CRI, there may be no invalid code points, but SINR_0 may represent an SINR less than or equal to -23 dB for the strongest SSBRI / CRI, and DIFFSINR_15 may represent a ΔSINR less than or equal to -15 dB. In some systems, the mapping between the reported 7-bit code points and 4-bit code points and the actual measured SINR values ​​may be defined by specifications (such as network specifications).

[0108] In some deployments, various devices in the wireless communication system 100 may support CSI reporting in an mTRP deployment. For example, when associated with a non-periodic resource setting, such a device may extend the RRC parameter CSI-AssociatedReportConfigInfo to be configured with two CMR sets, each of which may be configured with or associated with corresponding QCL information. When associated with a periodic resource or a semi-persistent resource setting, the resource setting may include two CMR sets. In some deployments, the device may support less than or equal to 2 beams per group M for some beam reporting options.

[0109] In some aspects, the UE 115 and the network entity 105 may support a serving cell specific beamforming codebook (e.g., a serving cell specific RRC configured beamforming codebook) that may be selected by the UE 115 via one or more code point indices of a first set of beams (referred to as set A) and a second set of beams (referred to as set B) involved in the CSI report. In some aspects, such a codebook may include an indication of an absolute beam shape or options for components associated with the beam shape (e.g., point direction and width information, or array structure and phase shift values). In such aspects, a connection or relationship regarding respective beam shapes of set A beams and set B beams may be indicated at various levels (e.g., from the network entity 105 to the UE 115), including a resource level, a resource set level, a CSI resource setting level, a CSI report setting level, or a MAC-CE or downlink control information (DCI) dynamic indication level.

[0110] In some systems, the codebook construction and the connection or relationship between the set A beams and the set B beams may be configured to assume or expect that the antenna reference point location is the same for different set A beams and set B beams, or to transmit the beams from the network entity 105 by using all antenna elements at the panel of the network entity 105. However, as the antenna array of the network entity 105 becomes larger (e.g., such as in a deployment of a large intelligent surface (LIS) or a reconfigurable / reflective intelligent surface (RIS) at the network entity 105), the network entity 105 may transmit using different transmit beams from different sub-arrays that are physically far away from each other. In other words, different transmit beams of the network entity 105 may be associated with various line-of-sight departure points, where some of such line-of-sight departure points may be relatively far away from each other. Such various line-of-sight departure points may be factors in beam prediction (e.g., information related to antenna location may affect receive beam selection and beam prediction performance at the UE 115). However, the UE 115 may not be aware of such various boresight off points for different transmit beams used by the network entity 105 , which may result in inaccurate beam prediction at the UE 115 .

[0111] Furthermore, while the UE 115 and the network entity 105 may support indicating individual antenna positions for different downlink positioning reference signal (DL-PRS) resources (e.g., physical positions of antennas within a grid of antenna panels, boresight departure points, or other indications of one or more antenna positions within one or more antenna panels), such indications may be associated with relatively large indication or configuration overhead (e.g., because such indications may be specifically indicated for each PRS resource). In some aspects, a more compact or efficient configuration of the relay may be more suitable for predictive beam management, particularly given the case where the codebook may change dynamically.

[0112] Thus, in some implementations, the UE 115 and the network entity 105 may support antenna positions for a specific configuration of a serving cell (e.g., ServCell). In some aspects, the antenna positions for a specific configuration of a serving cell may be configured or indicated together with a beamforming codebook for a specific configuration of a serving cell. In some implementations, the connection of the corresponding antenna positions may be indicated at various setting levels (including a resource level, a resource set level, a CSI resource setting level, a CSI report setting level, or a MAC-CE or DCI dynamic indication level) together with the corresponding beam shapes for the set A beam and the set B beam.

[0113] Figure 2 An example of a signaling diagram 200 that supports antenna position configuration for predictive beam management according to one or more aspects of the present disclosure is illustrated. The signaling diagram 200 may be implemented or implemented to implement aspects of the wireless communication system 100. For example, the signaling diagram 200 illustrates communications between the UE 115 and the network entity 105, which may be as described herein (including references to Figure 1 ) is an example of a corresponding device described in the embodiment of the present invention. The network entity 105 may send signaling to the UE 115 via the downlink 205, and the UE 115 may send signaling to the network entity 105 via the uplink 210. In some specific implementations, the UE 115 and the network entity 105 may support a beamforming codebook 215, and the network entity 105 may indicate antenna positions 220 and 225 of various channel resources associated with the beamforming codebook 215 according to the beamforming codebook.

[0114] The beamforming codebook 215 may be a codebook of beams that can be formed by a serving cell associated with the network entity 105 and may be configured via signaling associated with configuration of the serving cell (e.g., RRC configuration). In some aspects, the various channel resources associated with the beamforming codebook 215 may include a first set of channel resources for channel measurement and a second set of channel resources for beam prediction. The first set of channel resources for channel measurement may be associated with a set of beams 230, which may be associated with or referred to as a set of beams B, and the second set of channel resources for beam prediction may be associated with a set of beams 235, which may be associated with or referred to as a set of beams A. In some aspects, the set of beams 230 may be relatively wide beams, and the set of beams 235 may be relatively narrow beams.

[0115] As described herein, a set of beams A may be predicted and a set of beams B may be actually measured. For example, the network entity 105 may transmit one or more reference signals using each beam in the set of beams B via a channel resource in a first set of channel resources for channel measurement. In addition, the UE 115 may predict measurement information (e.g., signal strength, such as an L1-RSRP measurement result or an L1-SINR measurement result) for each subset of at least one subset of the set A beams associated with the network entity 105.

[0116] The first set of channel resources and the second set of channel resources may be associated with each other (e.g., connected), which may refer to how the UE 115 uses the measurement results of one or more channel resources in the first set of channel resources to predict the measurement results of one or more channel resources in the second set of channel resources. In addition, although described herein as the second set of channel resources for beam prediction, additionally or alternatively, the channel resources in the second set of channel resources may be part of a set of channel resources for channel measurement, wherein such a set of channel resources may be configured, indicated, or defined as being used for or associated with channel measurement or beam prediction functions. The UE 115 may receive configuration information associated with the first set of channel resources and the second set of channel resources via the beamforming codebook 215, CSI report settings, separate signaling, or any combination thereof, and potentially also receive information indicating an association (e.g., connection) between the first set of channel resources and the second set of channel resources.

[0117] In some implementations, the UE 115 and the network entity 105 may utilize a beamforming codebook 215 (e.g., a ServCell-specific beamforming codebook) for predictive beam management. For example, the UE 115 may receive an indication of the number (e.g., amount) of transmit antenna positions that may be identified by the beamforming codebook 215 within a particular serving cell and that may be applied to channel resources associated with the beamforming codebook 215. As described herein, the channel resources in the first set of channel resources may be referred to as channel measurement resources (CMRs) (including SSBs or CSI-RSs), and the channel resources in the second set of channel resources may be CMRs that are not actually transmitted (e.g., not expected to be transmitted by the network entity 105 or measured by the UE 115) or virtual resources or nominal resources.

[0118] like Figure 2As illustrated by the example of, the beamforming codebook 215 may indicate the antenna positions 220 (e.g., including antenna position 220-a and antenna position 220-b) of the channel resources in the first set of channel resources for channel measurement (which may be associated with the set of beams 230), and may indicate the antenna positions 225 (e.g., including antenna position 225-a, antenna position 225-b, antenna position 225-c, antenna position 225-d, antenna position 225-e, antenna position 225-f, antenna position 225-g, and antenna position 225-h) of the channel resources in the second set of channel resources for beam prediction (which may be associated with the set of beams 235). In some aspects, the set of beams 230 may be relatively wide beams and may be associated with the antenna positions 220, which are located at four corresponding points within the antenna panel 245. The set of beams 235 may be relatively narrow beams and may be associated with the antenna positions 225, which are located at 16 corresponding points around the four points associated with the set B beams.

[0119] In some examples, the beamforming codebook 215 may indicate the antenna positions 220 and 225 according to a differential antenna position configuration. For example, the configuration or indication of the antenna positions in the corresponding beamforming code points may be based on the configuration of a specifically defined antenna reference point position of the serving cell. In such examples, the indication of the antenna positions for a given beamforming code point may be made by indicating the differential position with respect to the specifically defined antenna reference point position of the serving cell. In other words, the network entity 105 may indicate the reference point positions specific to both the antenna panel 245 of the network entity 105 and the corresponding serving cell of the network entity 105, and may differentially indicate the antenna positions 220 and 225 with respect to the reference point positions via the beamforming codebook 215.

[0120] In addition to transmitting the antenna positions, the beamforming codebook 215 may further include the spatial information of the corresponding beam code points included in the beamforming codebook 215, and the spatial information may include beamforming gain information specific to the beam pointing direction or angle. Thus, the UE 115 may identify, select, or otherwise determine the antenna positions of both the first set of channel resources and the second set of channel resources (which may include CMR or virtual resources or nominal resources) based on additional connections that may be configured or indicated to associate resources with at least one code point within the beamforming codebook 215. Additional details regarding the spatial information included in the beamforming codebook 215 are illustrated and described with reference to Figure 3 illustrated and referenced Figure 3 are described.

[0121] In some implementations, the UE 115 and the network entity 105 may support a connection between a first set of channel resources (e.g., which may be associated with a set B beam) and a second set of channel resources (e.g., which may be associated with a set A beam) according to or based on the antenna position indicated by the beamforming codebook 215. In some aspects, for example, the UE 115 may also identify a connection (in terms of antenna position) between a first subset of resources within the first set of channel resources and a second subset of resources within the second set of channel resources based on a threshold distance. For example, the network entity 105 may configure (e.g., via RRC signaling) or indicate (e.g., via MAC-CE or DCI) that if an antenna position 225 of a second resource within the second set of channel resources is within a threshold distance (e.g., X centimeters) from a first resource within the first set of channel resources, then the first resource and the second resource (e.g., for beam prediction purposes) may be connected or associated. Additionally or alternatively, the network specification may indicate that a set of resources from the first set of channel resources and the second set of channel resources are associated or connected if antenna locations of the resources are within a threshold distance of each other.

[0122] In some implementations, a value or a set of possible values ​​(e.g., X) of the threshold distance may be defined or indicated by a network specification. Additionally or alternatively, the UE 115 may receive an indication of the threshold distance via signaling from the network entity 105. In some aspects, the threshold distance may be RRC configured. In such aspects, the value of X may be configured per serving cell with the beamforming codebook 215, by a CSI report setting, or by a CSI resource setting associated with one or both of the first set of channel resources and the second set of channel resources. In some aspects, the threshold distance may be MAC-CE indicated. In such aspects, the value of X may be indicated by a MAC-CE that activates a CSI report 240 (e.g., a semi-persistent CSI report) associated with the first set of channel resources and the second set of channel resources, or by a MAC-CE that activates a CSI resource set that is the first set of channel resources and the second set of channel resources. In some aspects, the threshold distance may be DCI indicated. In such aspects, when CSI reporting associated with the aperiodic CSI triggering state is triggered by DCI, the value of X may be configured by the aperiodic CSI triggering state configuration and indicated by the DCI.

[0123] If the second resource from the second set of channel resources is associated or connected to multiple first resources from the first set of channel resources, the UE 115 may identify, select, or otherwise determine a single first resource from the first set of channel resources that is connected to the second resource. In some implementations, the UE 115 may select the single first resource from the first set of channel resources based on the single first resource being associated with an antenna position that is closest to an antenna position of the second resource.

[0124] In addition, in some implementations, the UE 115 may select, identify, ascertain, or otherwise determine an association or connection between channel resources in the first set of channel resources and channel resources in the second set of channel resources based on a connection priority order of different codebook components. In other words, when identifying, selecting, ascertaining, or otherwise determining a connection or association between resources in the first set of channel resources and resources in the second set of channel resources, the UE 115 may support or consider a priority order between multiple codebook components (e.g., parameters or other information conveyed by the beamforming codebook 215). In some examples, the multiple codebook components may include antenna position differences between corresponding resources, beam pointing direction differences (e.g., in X 1 / X 2 dB beamwidth), beam shape differences, or phase shift value differences between corresponding resources.

[0125] In some implementations, connections between resources may be prioritized initially based on the first component, and secondarily based on the second component. For example, the UE 115 may first identify the connection based on the antenna position, and then identify (or narrow down) the connection based on the beam pointing direction. Thus, the UE 115 may identify a preliminary connection between a first set of channel resources and a second set of channel resources based on the corresponding antenna position, and may identify a refined connection between the first set of channel resources and the second set of channel resources based on the corresponding beam pointing direction of the channel resources. For another example, the UE 115 may first identify the connection based on the beam spot direction, and then identify (or narrow down) the connection based on the antenna position. In some aspects, the preliminary connection may include a connection between a plurality of first resources in the first set of channel resources and a second channel resource in the second set of channel resources, and the refined connection may include a connection between a smaller set of first resources (e.g., a single first resource) in the first set of channel resources and a second channel resource.

[0126] The UE 115 may receive an indication of one or more code points in the beamforming codebook 215 for the channel resources from the network entity 105. In some aspects, the UE 115 may receive the indication of the one or more code points via signaling for the CSI report 240. The UE 115 may accordingly identify a connection between the channel resources in the first set of channel resources and the channel resources in the second set of channel resources based on the indicated beamforming code points, and may associate the channel resources indicated by the beamforming code points along with any connected channel resources with a CSI report for a serving cell of the network entity 105.

[0127] In some implementations, the UE 115 and the network entity 105 may support QCL or reporting volume behavior based on the antenna position connection. For example, the UE 115 may identify the QCL or reporting volume or both based on the antenna position-based connection. In some examples, for the reporting volume associated with the second set of channel resources used for beam prediction, the UE 115 may address (e.g., include in the CSI report 240) a channel resource in the second set of channel resources that is connected to a first resource in the first set of channel resources that is associated with the strongest channel measurement result (e.g., the strongest L1-RSRP) among the remaining channel resources in the first set of channel resources.

[0128] For example, if the UE 115 measures that the beam 230-a associated with the first channel resource having the antenna position 220-a has the relatively largest signal strength, the UE 115 may include in the CSI report 240 the predicted signal strength of a second channel resource in the second set of channel resources, the second channel resource being connected to the first channel resource associated with the beam 230-a. In other words, the CSI report 240 may include the predicted L1-RSRP of the set A beam, the set A beam being connected to the beam 230-a for which the UE 115 measured the strongest L1-RSRP. In the example of the beamforming codebook 215, the second channel resource in the second set of channel resources may be connected to the first channel resource having the antenna position 220-a, the second channel resource being associated with the antenna positions 225-a, 225-b, 225-c, and 225-d, and the UE 115 may include the predicted signal strength of those second channel resources in the CSI report 240 accordingly.

[0129] Likewise, UE 115 may exclude predicted signal strengths for remaining channel resources in the second set of channel resources that are not connected to the first channel resources associated with beam 230-a from CSI report 240. In some aspects, UE 115 may receive (e.g., in the future) scheduled signaling using a receive beam based on a TCI state associated with a second resource in the second set of channel resources, wherein the receive beam used by UE 115 to receive signaling based on the TCI state associated with the second resource may be the same receive beam used by UE 115 to receive and measure reference signals via the connected first resource.

[0130] Thus, UE 115 may generate and send a CSI report 240 that includes at least one or more predicted signal strengths of one or more channel resources in the second set of channel resources. In some examples, UE 115 may also additionally include one or more measured signal strengths of one or more channel resources in the first set of channel resources in CSI report 240. Network entity 105 may receive CSI report 240 and may schedule communications between UE 115 and network entity 105 based on CSI report 240. For example, network entity 105 may select one or more (uplink or downlink) transmit beams or one or more (uplink or downlink) receive beams or both based on the predicted signal strengths included in CSI report 240, and schedule communications with UE 115 accordingly.

[0131] Figure 3 Examples of beamforming codebook configurations 300 and 301 supporting antenna position configuration for predictive beam management according to one or more aspects of the present disclosure are illustrated. The example beamforming codebook configurations 300 and 301 may be implemented or implemented to implement or facilitate aspects of the wireless communication system 100 or the signaling diagram 200. For example, the UE 115 and the network entity 105 (which may be examples of corresponding devices described herein) may support one or both of the beamforming codebook configurations 300 and 301, or a combination of the beamforming codebook configurations 300 and 301, so that the beamforming codebook 215 utilizes beam prediction based on antenna position. The beamforming codebook 215 may include a plurality of codepoints 305 indicating antenna positions 310 and spatial information of channel resources in a first set of channel resources associated with channel measurement and channel resources in a second set of channel resources associated with beam prediction. In some aspects, each code point 305 may include or be associated with a corresponding antenna position 310 and corresponding spatial information for a corresponding channel resource.

[0132] As illustrated in the example beamforming codebook configuration 300 (which may be associated with the multi-component beamforming codebook 215), each codepoint 305 may include a plurality of fields associated with: an indication of an antenna position 310 (which may be defined as the point at which the associated beam propagates from an antenna array or panel of the network entity 105), an indication of a reference beam shape 315 (e.g., a particular angular beamforming gain), and an indication of a beam pointing direction 320 (e.g., an indication of a boresight direction). In some examples, the indication of the antenna position 310 may include a value of one of a set of approximately 20 options; the indication of the reference beam shape 315 may include a value of one of a set of approximately 3 options; and the indication of the beam pointing direction 320 may include a value of one of a set of approximately 10 options. In a specific implementation associated with the beamforming codebook configuration 300, the spatial information indicated by the beamforming codebook 215 may include a reference beam shape and a beam pointing direction (e.g., a boresight direction).

[0133] As illustrated by the example beamforming codebook configuration 301, each codepoint 305 may include a plurality of fields associated with an indication of an antenna position 310 (which may be defined as the center of one or more antenna elements involved in transmission using the associated beam), an indication of an antenna array structure 325, and an indication of a set of phase shift values ​​330. The indication of the antenna array structure 325 may be associated with or otherwise indicate a layout and orientation of a set of antenna elements, wherein the layout of the antenna elements may identify a distance from the antenna position to the respective antenna element. Additionally, the indication of the set of phase shift values ​​330 may be associated with the respective antenna element. In a specific implementation associated with the beamforming codebook configuration 301, the spatial information indicated by the beamforming codebook 215 may include an antenna array structure and a set of phase shift values.

[0134] Figure 4An example of a process flow 400 supporting antenna position configuration for predictive beam management according to one or more aspects of the present disclosure is illustrated. The process flow 400 may be implemented or implemented to facilitate or implement aspects of the wireless communication system 100, the signaling diagram 200, the beamforming codebook configuration 300, or the beamforming codebook configuration 301. For example, the process flow 400 illustrates communication between a UE 115 and a network entity 105 (which may be examples of corresponding devices as described herein). In some specific implementations, the UE 115 and the network entity 105 may support a beamforming codebook according to which the UE 115 and the network entity 105 may communicate antenna positions that are associated with channel resources in both a first set of channel resources associated with channel measurement and a second set of channel resources associated with beam prediction. Thus, the UE 115 and the network entity 105 may support beam prediction across various deployments, including deployments where the network entity 105 supports relatively large antenna panels with multiple subarrays.

[0135] In the following description of the process flow 400, operations (such as reporting or providing) may be performed in a different order than shown, or operations performed by the example device may be performed in a different order or at a different time. Some operations may also be excluded from the process flow 400, or other operations may be added to the process flow 400. In addition, although some operations or signaling are shown as occurring at different times for discussion purposes, these operations may actually occur simultaneously.

[0136] At 405, UE 115 may receive a beamforming codebook (eg, a codebook configured by Figure 2 and Figure 3 Illustrated and referenced Figure 2 and Figure 3 The beamforming codebook 215 described above is associated with a serving cell of the network entity 105. In some implementations, the beamforming codebook may indicate antenna positions of a first set of multiple channel resources associated with channel measurement and a second set of multiple channel resources associated with beam prediction (such as antenna positions 220 and antenna positions 225 via the indication of antenna position 310, as shown in FIG. Figure 2 and Figure 3 Illustrated and referenced Figure 2 and Figure 3In some aspects, the antenna position may be associated with an antenna panel of a network entity 105 associated with a serving cell. In some aspects, the beamforming codebook may include a plurality of codepoints, and each of the plurality of codepoints may include a corresponding antenna position and corresponding spatial information for a corresponding channel resource. Thus, the codebook may be used to connect the set A beams and the set B beams for predictive beam management based on one or both of the antenna position and the spatial information.

[0137] At 410, UE 115 may receive, from network entity 105, an indication of a reference point location associated with an antenna panel of the network entity associated with a serving cell. In such implementations where UE 115 receives an indication of the reference point location, the antenna location indicated by the beamforming codebook may be indicated distinctly relative to the reference point location.

[0138] At 415, the UE 115 may receive an indication of a threshold distance from the network entity 105, the threshold distance being associated with a correspondence between channel resources in the first set of channel resources and channel resources in the second set of channel resources. In such specific implementations where the UE 115 receives the indication of the threshold distance, the UE 115 may use the indication to identify, select, ascertain, or otherwise determine a connection or association between the first set of channel resources and the second set of channel resources for beam prediction purposes. For example, if a first channel resource in the first set of channel resources is within a threshold distance of a second channel resource in the second set of channel resources, the UE 115 may use a signal strength measurement result of the first channel resource to predict a signal strength of the second channel resource.

[0139] At 420, the UE 115 may receive an indication of one or more code points associated with the beamforming codebook. In some aspects, the one or more code points may indicate one or more first channel resources from a first set of channel resources for the UE 115 to measure. The UE 115 may also additionally use the one or more code points to identify one or more second channel resources in a second set of channel resources that are connected or associated with the indicated one or more first channel resources (e.g., based on corresponding antenna positions). Thus, the one or more code points may be associated with the one or more second channel resources in the second set of channel resources, and the UE 115 may accordingly predict the signal strength associated with the one or more second channel resources. The UE 115 may predict the signal strength associated with the one or more second channel resources based on the channel measurement results of the one or more first channel resources.

[0140] At 425, the network entity 105 may send one or more reference signals via one or more channel resources in the first set of channel resources (e.g., one or more first channel resources indicated by one or more code points). The UE 115 may receive and measure a set of signal strengths of the one or more reference signals via one or more channel resources in the first set of channel resources.

[0141] At 430, the UE 115 may predict one or more signal strengths associated with one or more channel resources in the second set of channel resources based on the set of channel measurement results associated with the one or more channel resources in the first set of channel resources, the antenna position, and the spatial information. For example, if a first channel resource in the first set of channel resources and a second channel resource in the second set of channel resources are connected or associated based on the corresponding antenna position or the spatial information or both, the UE 115 may predict the signal strength of the second channel resource based on the channel measurement results of the first channel resource.

[0142] At 435, the UE 115 may send a CSI report to the network entity 105, the CSI report including predicted signal strengths associated with one or more channel resources in the second set of channel resources. In some aspects, the UE 115 may include in the CSI report predicted signal strengths of channel resources in the second set of channel resources that are concatenated or associated with channel resources in the first set of channel resources for which the UE 115 measured a maximum signal strength (e.g., a signal strength that is relatively greater than the remaining signal strengths in the measured signal strengths associated with the first set of channel resources). In some aspects, the UE 115 may include any combination of the following: predicted or measured L1-RSRP, L1-SINR, rank indication (RI), channel quality indicator (CQI), precoding matrix indicator (PMI), or layer indicator (LI).

[0143] At 440, the UE 115 may receive control signaling associated with which directional beams are to be used for communicating with the network entity 105. For example, the UE 115 may receive an indication of which one or more beams the network entity 105 may use based on the CSI report (e.g., based on the predicted signal strength) to communicate with the UE 115. Additionally or alternatively, the control signaling may indicate which one or more beams the UE 115 may use based on the CSI report (e.g., based on the predicted signal strength) to communicate with the network entity 105. The UE 115 may receive the control signaling from the network entity 105 via a DCI, a MAC-CE, a downlink control channel, a downlink data channel, or a downlink shared channel.

[0144] At 445, UE 115 may communicate with network entity 105 in accordance with the control signaling and based on the CSI report. For example, UE 115 may receive downlink signaling from network entity 105 via: UE 115 predicts a downlink beam with a relatively high signal strength in the CSI report, or a beam otherwise indicated via control signaling. UE 115 may communicate with network entity 105 via one or more control channels, data channels, or shared channels.

[0151] In some examples, communication manager 520 may be configured to perform various operations (e.g., receive, obtain, monitor, output, send) using or otherwise cooperating with receiver 510, transmitter 515, or both. For example, communication manager 520 may receive information from receiver 510, transmit information to transmitter 515, or be integrated in conjunction with receiver 510, transmitter 515, or both to obtain information, output information, or perform various other operations as described herein.

[0165] In some examples, the second set of multiple channel resources includes multiple channel resources of the second channel resource and is associated with an antenna position within the threshold distance of the first antenna position of the first channel resource. In some examples, the second channel resource is associated with the first channel resource for beam prediction based on the distance between the first antenna position and the second antenna position being a relatively minimum distance.

[0166] In some examples, the indication of the threshold distance is received from the network entity via radio resource control signaling, medium access control (MAC)-control element (CE) or DCI message, or any combination thereof.

[0168] In some examples, if the first signal strength is the relatively large signal strength, the first group of predicted signal strengths associated with the first set of channel resources in the second set of multiple channel resources is included in the channel state information report; and if the second signal strength is the relatively large signal strength, the second group of predicted signal strengths associated with the second set of channel resources in the second set of multiple channel resources is included in the channel state information report.

[0174] In some examples, each code point in the set of multiple code points includes information indicating an antenna position associated with a corresponding channel resource, an antenna array structure, and a set of phase shift values ​​for antenna elements of the antenna array structure.

[0175] Figure 8 A diagram of a system 800 including a device 805 supporting antenna position configuration for predictive beam management according to one or more aspects of the present disclosure is shown. The device 805 may be an example of a device 505, a device 605, or a UE 115 as described herein, or include components thereof. The device 805 may communicate (e.g., wirelessly) with one or more network entities 105, one or more UEs 115, or any combination thereof. The device 805 may include components for two-way voice and data communications, including components for sending communications and receiving communications, such as a communication manager 820, an input / output (I / O) controller 810, a transceiver 815, an antenna 825, a memory 830, a code 835, and a processor 840. These components may be electronically communicated or otherwise coupled (e.g., operatively, communicatively, functionally, electronically, electrically) via one or more buses (e.g., a bus 845).

[0176] I / O controller 810 can manage input signals and output signals of device 805. I / O controller 810 can also manage peripheral devices that are not integrated into device 805. In some cases, I / O controller 810 can represent a physical connection or port to an external peripheral device. In some cases, I / O controller 810 can utilize an operating system, such as or another known operating system. Additionally or alternatively, I / O controller 810 may represent or interact with a modem, keyboard, mouse, touch screen, or similar device. In some cases, I / O controller 810 may be implemented as part of a processor, such as processor 840.
