Technical Field

[0003] The following relates to wireless communications, including dynamic aggregate occupancy grid generation. Background Art

[0004] 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).

[0005] In some examples, the wireless communication system may support one or more automotive applications, such as advanced driver assistance systems (ADAS) or positioning. To support one or more automotive applications, a UE (e.g., a vehicle) may send occupancy information to a network entity. The occupancy information may inform the network entity of other UEs near an object or UE. Summary of the invention

[0006] The described technology relates to improved methods, systems, devices, and apparatuses that support dynamic aggregated occupancy grid generation. For example, the described technology provides a network entity to generate an aggregated occupancy grid. In some examples, the network entity may send control information indicating an occupancy grid (e.g., a configuration associated with the occupancy grid) to a user equipment (UE). The occupancy grid may include a set of cells corresponding to a geographic area, and the set of cells may correspond to a set of resource elements (REs) of a time-frequency grid. Upon receiving the control information, the UE may receive signaling indicating occupancy information for one or more cells in the set of cells from one or more sensors, and for each of the one or more occupied cells, send signaling via the RE corresponding to the occupied cell. The network entity may monitor the set of REs and determine whether the cell is occupied based on the energy level of the RE corresponding to each cell in the set of cells. If the energy level of the RE exceeds a threshold, the network entity may determine that the cell corresponding to the RE is occupied. If the energy level of the RE is lower than the threshold, the network entity may determine that the cell corresponding to the RE is not occupied. The network entity may generate an aggregated occupancy grid based on determining whether each cell in the set of cells is occupied, and potentially send signaling indicating the aggregated occupancy grid to the UE.

The method may include: receiving control information indicating an occupied grid, the occupied grid including a set of multiple cells corresponding to a geographic area, the cells in the set of multiple cells corresponding to REs in a set of multiple REs of a time-frequency resource grid; receiving first signaling indicating occupancy information of a set of cells in the set of multiple cells from one or more sensors; and for each cell in the set of cells that is occupied according to the occupancy information, sending second signaling via REs in the set of multiple REs that correspond to the occupied cell.

[0053] In some examples, high definition (HD) maps may benefit automotive applications such as advanced driver assistance systems (ADAS) and positioning. In order to generate an HD map, a network entity may aggregate occupancy grids from multiple user equipments (UEs). In some examples, a UE may use one or more sensors to generate an occupancy map. First, the UE may determine a geographic area based on the range of one or more sensors and divide the geographic area into cells. The UE may then determine whether each cell of the geographic area is occupied or unoccupied, and send the information to the network entity in the form of an occupancy map. After receiving the occupancy map from multiple UEs, the network entity may combine the occupancy grids to determine the HD map. For stationary objects, multiple UEs may not sense and transmit their occupancy grids during the same time interval, thereby allowing the network to control the communication overhead associated with sending the occupancy grids. However, for dynamic objects, multiple UEs may sense and transmit their occupancy grids during the same time interval, which may increase the communication overhead associated with sending the occupancy grid. Thus, an efficient process for generating collaborative dynamic occupancy grids for multiple UEs with potentially high update rates may be beneficial.

[0054] As described herein, a network entity may generate an HD map by combining occupancy grids from multiple UEs using over-the-air (OTA) aggregation, where the generated HD map may also be referred to as an aggregated occupancy grid. In some examples, a set of UEs may receive a configuration message from a network entity. The configuration message may include an indication of a global geographic area for the HD map and a shape or size of cells included in the global geographic area. In addition, the configuration message may include a mapping of cells to REs. The group of UEs may determine that their geographic area is included in the global geographic area and divide their geographic area into cells based on the indicated cell size or cell shape.

[0055] The set of UEs may then determine (e.g., using sensors) whether their geographic cell is occupied. If the cell is determined to be occupied, the UE may send signaling on the RE mapped to the cell. If the cell is determined to be unoccupied, the UE may not send (i.e., suppress) signaling on the RE mapped to the cell. Because the cells of the set of UEs may overlap, such as when multiple UEs detect occupancy at the same geographic location, multiple UEs may send signaling on the same RE. Thus, the network entity may determine whether the cell is occupied based on the energy of the RE corresponding to the cell (e.g., OTA aggregation). If the energy of the RE corresponding to the cell is higher than a threshold, the network entity may determine that the cell is occupied, and if the energy of the RE corresponding to the cell is lower than a threshold, the network entity may determine that the cell is unoccupied. The network entity may generate an HD map (or aggregated occupancy grid) based on determining whether the cell is occupied. By utilizing OTA aggregation, the resources used to send the occupancy grid may become independent of the number of UEs included in the set of UEs, which may reduce overhead signaling.

[0056] Aspects of the present disclosure are first described in the context of wireless communication systems. Additional aspects are described in the context of occupancy grid generation schemes and process flows. Aspects of the present disclosure are further illustrated and described by and with reference to apparatus diagrams, system diagrams, and flow diagrams related to dynamic aggregated occupancy grid generation.

[0057] Figure 1 An example of a wireless communication system 100 supporting dynamic aggregated occupancy grid generation 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.

[0058] 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 nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly 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).

[0059] 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 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 communications with various types of devices, such as Figure 1 Other UEs 115 or network entities 105 are shown.

[0060] 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, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. 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.

[0061] 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 through 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), and other examples or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0062] 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).

[0063] 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)).

[0064] The functional split between CU 160, DU 165, and RU 170 is flexible and can 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 can be employed between CU 160 and DU 165, such that CU 160 can support one or more layers of a protocol stack and DU 165 can support one or more different layers of a protocol stack. In some examples, CU 160 can 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 DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 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 a protocol layer (e.g., some functions of a 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., an open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 that communicate via those communication links.

[0065] 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.

[0066] In the case 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 dynamic aggregated occupancy grid generation as described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0067] 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 suitable terminology, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. 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, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0068] The UE 115 described herein may be capable of communicating with various types of devices such as other UEs 115 which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0069] 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 with 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).

[0070] 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 using MCM technology, RE 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 subcarrier spacing may be inversely related. The number of bits carried by each RE 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 number of REs (e.g., in the transmission duration) and a relatively high order 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.

[0071] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, T s =1 / (Δf max ·N f ) seconds sampling period, where the sampling period, Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The 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).

[0072] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the 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.

[0073] A subframe, slot, mini-slot, or 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 number 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)).

[0074] Carrier multiplexing physical channels may be used for communication according to various techniques. Physical control channels and physical data channels may be multiplexed via downlink carriers for signaling using, for example, 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 or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE115 may monitor or search a control region for 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 .

[0075] 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.

[0076] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may provide automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or acquire information and relay such information to a central server or application that uses the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, wildlife monitoring, weather and geographic event monitoring, queue management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.

[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 or 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 may be 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 or (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 of such a group may be outside of 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] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units), or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170) using vehicle-to-network (V2N) communication, or both.

[0080] The core network 130 may provide user authentication, access authorization, 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 stratum (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 through the 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.

[0081] 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 ranges from about 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 lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[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 network entity 105 and UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands may be based on 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, and the like.

[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 collection of multiple rows and columns of antenna ports 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] 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 transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular direction relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving 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 direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0085] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority processing and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection that supports a radio bearer for user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map a transport channel to a physical channel.

[0086] In some examples, the network entity 105 may generate an HD map by combining occupancy grids from multiple UEs 115 using OTA aggregation, where the generated HD map may also be referred to as an aggregated occupancy grid. In some examples, a group of UEs 115 may receive a configuration message from the network entity 105. The configuration message may include an indication of a global geographic area for the HD map and a shape or size of cells included in the global geographic area. In addition, the configuration message may include a mapping of cells to REs. The set of UEs 115 may determine that their geographic area is included in the global geographic area and divide their geographic area into cells according to the indicated cell size or cell shape.

[0087] The set of UEs 115 may then determine (e.g., using sensors) whether their geographic cell is occupied. If the cell is determined to be occupied, the UE 115 may send signaling on the REs mapped to the cell. If the cell is determined to be unoccupied, the UE 115 may not send (i.e., suppress) signaling on the REs mapped to the cell. Because the cells of the set of UEs may overlap, such as when multiple UEs detect occupancy at the same geographic location, multiple UEs 115 may send signaling on the same RE. Thus, the network entity 105 may determine whether the cell is occupied based on the energy of the REs corresponding to the cell (e.g., OTA aggregation). If the energy of the REs corresponding to the cell is above a threshold, the network entity 105 may determine that the cell is occupied, and if the energy of the REs corresponding to the cell is below a threshold, the network entity 105 may determine that the cell is unoccupied. The network entity 105 may generate an HD map (or aggregated occupancy grid) based on determining whether the cell is occupied. By utilizing OTA aggregation, the resources used to send the footprint grid may become independent of the number of UEs 115 included in the set of UEs 115, which may reduce overhead signaling.

[0088] Figure 2An example of a network architecture 200 (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) supporting dynamic aggregated occupancy grid generation according to one or more aspects of the present disclosure is illustrated. The network architecture 200 may illustrate an example for implementing one or more aspects of the wireless communication system 100. The network architecture 200 may include one or more CUs 160-a, which may communicate directly with the core network 130-a via a backhaul communication link 120-a, or indirectly with the core network 130-a through one or more disaggregated network entities 105 (e.g., a near RT RIC 175-b via an E2 link, or a non-RT RIC 175-a associated with an SMO 180-a (e.g., an SMO framework), or both. The CU 160-a may communicate with one or more DUs 165-a via corresponding midhaul communication links 162-a (e.g., an F1 interface). The DU 165-a may communicate with one or more RUs 170-a via corresponding fronthaul communication links 168-a. A RU 170-a can be associated with a corresponding coverage area 110-a and can communicate with a UE 215 via one or more communication links 125-a. In some implementations, a UE 215 can be served simultaneously by multiple RUs 170-a.

[0089] Each of the network entities 105 of the network architecture 200 (e.g., CU 160-a, DU 165-a, RU 170-a, non-RT RIC 175-a, near-RT RIC 175-b, SMO 180-a, open cloud (O-Cloud) 205, open eNB (O-eNB) 210) may include one or more interfaces or may be coupled to one or more interfaces configured to receive or send signals (e.g., data, information) via a wired or wireless transmission medium. Each network entity 105 or an associated processor (e.g., a controller) that provides instructions to an interface of the network entity 105 may be configured to communicate with one or more of the other network entities 105 via a transmission medium. For example, these network entities 105 may include a wired interface that is configured to receive signals on a wired transmission medium or to send signals to one or more of the other network entities 105 on a wired transmission medium. Additionally or alternatively, the network entity 105 may include a wireless interface, which may include a receiver, a transmitter, or a transceiver (e.g., an RF transceiver) configured to receive signals on a wireless transmission medium, or to send signals to one or more of the other network entities 105 on a wireless transmission medium, or both.

[0090] In some examples, CU 160-a may host one or more higher layer control functions. Such control functions may include RRC, PDCP, SDAP, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 160-a. CU 160-a may be configured to handle user plane functionality (e.g., CU-UP), control plane functionality (e.g., CU-CP), or a combination thereof. In some examples, CU 160-a may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU 160-a may be implemented to communicate with DU 165-a for network control and signaling.

[0091] DU 165-a may correspond to a logical unit that includes one or more functions (e.g., base station functions, RAN functions) for controlling the operation of one or more RUs 170-a. In some examples, DU 165-a may at least partially host one or more of the RLC layer, the MAC layer, and one or more aspects of the PHY layer (e.g., a high PHY layer, such as modules for FEC encoding and decoding, scrambling, modulation and demodulation, etc.), which depends at least in part on functional splits, such as those defined by the Third Generation Partnership Project (3GPP). In some examples, DU 165-a may also host one or more low PHY layers. Each layer may be implemented using an interface that is configured to communicate signals with other layers hosted by DU 165-a or with control functions hosted by CU 160-a.

[0092] In some examples, lower layer functionality may be implemented by one or more RUs 170-a. For example, a RU 170-a controlled by a DU 165-a may correspond to a logical node that hosts RF processing functions or low PHY layer functions (e.g., performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.) or both based at least in part on functional splitting (such as lower layer functional splitting). In such an architecture, RU 170-a may be implemented to handle over-the-air (OTA) communications with one or more UEs 215. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with RU 170-a may be controlled by corresponding DU 165-a. In some examples, such a configuration may enable DU 165-a and CU 160-a to be implemented in a cloud-based RAN architecture (such as a vRAN architecture).

[0093] The SMO 180-a may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network entities 105. For non-virtualized network entities 105, the SMO 180-a may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (e.g., an O1 interface). For virtualized network entities 105, the SMO 180-a may be configured to interact with a cloud computing platform (e.g., O-Cloud 205) to perform network entity lifecycle management (e.g., instantiating virtualized network entities 105) via a cloud computing platform interface (e.g., an O2 interface). Such virtualized network entities 105 may include, but are not limited to, CU 160-a, DU 165-a, RU 170-a, and near-RT RIC 175-b. In some specific implementations, the SMO 180-a may communicate (e.g., via an O1 interface) with components configured according to a 4G RAN. Additionally or alternatively, in some implementations, the SMO 180-a may communicate directly with one or more RUs 170-a via an O1 interface. The SMO 180-a may also include a non-RT RIC 175-a configured to support the functionality of the SMO 180-a.

[0094] The non-RT RIC 175-a may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence (AI) or machine learning (ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 175-b. The non-RT RIC 175-a may be coupled to or communicate with the near-RT RIC 175-b (e.g., via an A1 interface). The near-RT RIC 175-b may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions on an interface (e.g., via an E2 interface) that connects one or more CUs 160-a, one or more DUs 165-a, or both, and the O-eNB 210 with the near-RT RIC 175-b.

[0095] In some examples, in order to generate an AI / ML model to be deployed in the near-RT RIC 175-b, the non-RT RIC 175-a may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 175-b and may be received from a non-network data source or from a network function at the SMO 180-a or the non-RT RIC 175-a. In some examples, the non-RT RIC 175-a or the near-RT RIC 175-b may be configured to tune RAN behavior or performance. For example, the non-RT RIC 175-a may monitor long-term trends and patterns of performance and employ an AI model or ML model to perform corrective actions through the SMO 180-a (e.g., via reconfiguration of O1) or via the generation of a RAN management policy (e.g., an A1 policy).

[0096] Figure 3 An example of a wireless communication system 300 supporting dynamic aggregated occupancy grid generation according to one or more aspects of the present disclosure is illustrated. In some examples, the wireless communication system 300 may include aspects of the wireless communication system 100 and the network architecture 200. For example, the wireless communication system 300 may include a network entity 305, which may be as described in reference Figure 1 The wireless communication system 300 may also include UE 315, which may be as shown in FIG. Figure 1 and Figure 2 The examples of UE 115 and UE 215 are described. In some examples, UE 315 can be an example of a vehicle UE (VUE).

[0097] In some examples, UE 315 may generate an occupancy grid 320. The occupancy grid 320 of UE 315 may indicate the location of other UE 315 or objects near or around UE 315, and may be helpful for automobile operations such as positioning and ADAS. In some examples, the occupancy grid 320 may be associated with a geographic area. The geographic area may represent the range in which UE 315 can accurately detect other UE 315 or objects. In some examples, UE 315 may include a sensor (e.g., a camera, a lidar, or a radar), and the geographic area may correspond to the range of the sensor. In addition, the geographic area may be divided into a plurality of smaller geographic areas referred to as cells. The cells included in the geographic area may vary in size or shape or have the same size and shape. When generating the occupancy grid 320, UE 315 may determine the geographic area and the cells that make up the geographic area. UE 315 may then determine whether each cell is occupied or unoccupied, and potentially send the occupancy information (e.g., occupancy grid 320) to network entity 305. If the UE 315 senses (eg, using a sensor) that another UE 315 or object is present in the cell, the cell may be considered occupied. If the UE 315 does not sense that another UE 315 or object is present in the cell, the cell may be considered unoccupied.

[0098] The occupancy grid 320 of UE 315 can enhance the understanding of the area around UE 315, but the information provided by the occupancy grid of UE 315 may be limited. As an example, the occupancy grid 320 of UE 315 may be limited by the range of the sensor or the field of view of the sensor. For example, UE 315 may be equipped with a single sensor (e.g., radar) with a field of view of 20 degrees relative to the visual axis and a range of 150 meters. The resulting occupancy grid 320 of UE 315 may include the same limitations. In addition, the occupancy grid 320 of UE 315 may be affected by visibility gaps. For example, due to occlusion (e.g., buildings), even if another UE 315 is within the range of UE 315, the other UE 315 may not be visible to UE 315. Thus, it may be beneficial to fuse the occupancy grid 320 generated by each UE 315 (e.g., UE 315-a, UE 315-b, and UE 315-c) in the area and generate an aggregated occupancy grid 325.

[0099] To create an aggregate occupancy grid 325, a collection of UEs 315 within an area (e.g., UE 315-a, UE 315-b, and UE 315-c) may individually generate their own occupancy grids 320. For example, UE 315-a may generate occupancy grid 320-a, UE 315-b may generate occupancy grid 320-b, and UE 315-c may generate occupancy grid 320-c. After generating their own individual occupancy grids 320, UE 315-a, UE 315-b, and UE 315-c may send their occupancy grids 320 to a network entity 305 (e.g., a central server), and upon receiving the occupancy grids 320, the network entity 305 may combine the received occupancy grids 320 to generate an aggregate occupancy grid 325. In some examples, the aggregate occupancy grid 325 may indicate the location of a stationary object. In this case, when a UE 315 (e.g., any one of UE 315-a, UE 315-b, or UE 315-c) passes through an area, the UE 315 sends its occupancy grid 320 to the network entity 305 of the area, and the network entity 305 may accumulate the occupancy grids 320 from different UEs 315 over time and generate an accurate aggregated occupancy grid 325 of stationary objects in the area. To create such an aggregated occupancy grid 325, since the objects are stationary, the UE 315 may not need to sense or send their occupancy grids 320 during the same duration (e.g., at the same time). This may allow the network entity 305 to control the communication overhead associated with sending the occupancy grid 320.

[0100] However, it may also be helpful for the network entity 305 to track dynamic objects for applications such as ADAS. To create an aggregate occupancy grid for dynamic objects, the UEs 315 may sense and send their own individual occupancy grids 320 to the network entity 305 during the same duration. Additionally, the UEs 315 may send their own individual occupancy grids at a high frequency proportional to the dynamics of the environment. Sending occupancy grids 320 in this manner may result in greater communication overhead than the communication overhead associated with sending occupancy grids 320 for stationary objects.

[0101] As described herein, the network entity 305 may generate an aggregated occupancy grid 325 of a dynamic object using OTA aggregation. In some examples, UE 315-a, UE 315-b, and UE 315-c may receive (e.g., sent via broadcast) control information 310. The control information 310 may include a configuration for aggregated occupancy grid generation using OTA aggregation. For example, the control information 310 may include an indication of one or more of a geographic area of ​​the aggregated occupancy grid 325, a size of a cell included in the geographic area of ​​the aggregated occupancy grid 325, or a shape of a cell included in the geographic area of ​​the aggregated occupancy grid 325. In addition, the control information 310 may indicate a mapping between cells included in the geographic area of ​​the aggregated occupancy grid 325 and RE 330. The mapping may be an example of a one-to-one mapping. That is, a single cell included in the geographic area of ​​the aggregated occupancy grid 325 may be mapped to a single RE. Additionally, the control information 310 may include an indication of one or more time slots for sending the occupancy grid 320.

[0102] In some examples, the control information 310 may be sent to the UE 315 according to a certain periodicity (e.g., configured by the network entity 305). In another example, the control information 310 may be sent to the UE 315 dynamically. That is, the network entity 305 may decide when to send the control information 310. In yet another example, the control information 310 may be sent to the UE 315 after a request from one of the UEs 315. For example, the UE 315-a may send a request for the control information 310 to the network entity 305, and upon receiving the control information 310, the network entity 305 may send the control information 310 to one or more of the UEs 315.

[0103] In some examples, the control information 310 or the information included in the control information 310 (e.g., a configuration for generating an occupancy grid using OTA aggregation) may be valid for a certain duration. In one example, the control information 310 at the UE 315 may be valid until the UE 315 receives a second control information from the network entity 305, the second control information indicating a second configuration for generating an occupancy grid using OTA aggregation. In another example, the control information 310 may be valid for multiple aggregation rounds (unless the second control information is received earlier than the aggregation number is satisfied). In this example, each time the UE 315 sends an occupancy grid 320 to the network entity 305 according to the control information 310, the UE may increment a counter. If the counter exceeds the number of aggregation rounds (e.g., a threshold), the UE 315 may stop using the control information 310. That is, the UE 315 may stop sending (e.g., contributing) its occupancy grid 320 according to the control information 310. In some examples, each time the network entity 305 receives the occupancy grid 320 from the UE 315, the network entity may also increment a counter, and if the counter exceeds a number of aggregation rounds (e.g., a threshold), the network entity 305 may send second control information to the UE 315, the second control information indicating a second configuration for occupancy grid generation using OTA aggregation. Upon receiving the second control information, the UE 315 may switch from sending the occupancy grid 320 according to the control information 310 to sending the occupancy grid according to the second control information. In some examples, the threshold number of aggregation rounds may be indicated to the UE 315 via RRC signaling or included in the control information 310.

[0104] Upon receiving the control information 310 from the network entity 305, the UEs 315 (e.g., UE 315-a, UE 315-b, and UE 315-c) may determine that the geographic areas of their respective occupancy grids 320 overlap at least a portion of the geographic area of ​​the aggregated occupancy grid 325. As an example, the UE 315-a may determine that its corresponding geographic area overlaps with a first set of cells included in the geographic area of ​​the aggregated occupancy grid 325. Additionally, the UE 315-b and the UE 315-c may determine that their corresponding geographic areas overlap with a second set of cells and a third set of cells included in the geographic area of ​​the aggregated occupancy grid 325, respectively.

[0105] UE 315 may then sense whether each cell in their respective cell set is occupied or unoccupied during the same duration. If UE 315 determines that a cell is occupied, UE 315 may send signaling on RE 330 corresponding to the cell (e.g., according to the cell to RE mapping indicated in control information 310). In some examples, the signaling may indicate a number greater than or equal to 1, and in some cases, the number may be a plural number. If UE 315 determines that a cell is unoccupied, UE 315 may suppress sending signaling on RE 330 corresponding to the cell. In some examples, the geographic areas of the corresponding UE 315 may overlap. For example, the cells included in the geographic area of ​​the aggregated occupancy grid 325 may be included in the first set of cells and the second set of cells. In this example, if UE 315-a and UE 315-b sense that a cell is occupied, UE 315-a and UE 315-b may send signaling on the same RE 330 corresponding to the cell. If the UEs 315 determine that the geographic areas associated with their respective occupancy grids 320 do not overlap with the geographic area of ​​the aggregated occupancy grid 325, the UEs 315 may not generate their occupancy grids 320 and may not participate in aggregation.

[0106] At the network entity 305, the aggregated occupancy grid 325 may be generated using OTA aggregation. The network entity 305 may monitor the REs 330 corresponding to the cells included in the geographic area of ​​the aggregated occupancy grid 325, and measure the energy of each RE 330 (e.g., measure the energy of the signaling received through each RE 330). If the energy of the RE 330 exceeds the threshold, the network entity 305 may determine that the cell corresponding to the RE 330 is occupied. If the energy of the RE 330 does not exceed the threshold, the network entity 305 may determine that the cell corresponding to the RE 330 is not occupied. As described above, if the cell is not occupied, the UE 315 whose geographic area includes the cell may not send signaling on the RE 330 corresponding to the cell, and thus, the energy received from the RE 330 may not exceed the threshold. Alternatively, if the cell is occupied, the UE 315 whose geographic area includes the cell may send signaling on the RE 330 corresponding to the cell, and thus, the energy received from the RE 330 may exceed the threshold. As described above, if the cell corresponding to RE 330 is occupied, a single UE 315 or multiple UEs 315 may send signaling on RE 330 (e.g., if the geographic areas of two or more UEs 315 overlap, multiple UEs 315 may send signaling on the RE). Regardless of whether zero, one, or more UEs 315 are contributing to the energy of RE 330, the methods described herein are applicable. Thus, in some examples, the methods described herein do not depend on the number of UEs 315 contributing to the energy of RE 330.

[0107] Figure 4 An example of an occupancy grid generation scheme 400 supporting dynamic aggregated occupancy grid generation according to one or more aspects of the present disclosure is illustrated. In some examples, the occupancy grid generation scheme 400 can implement aspects of the wireless communication system 100, the network architecture 200, and the wireless communication system 300. For example, the occupancy grid generation scheme 400 can be implemented by a network entity, which can be a reference Figure 1 and Figure 3 The occupancy grid generation scheme 400 may be implemented by a UE, which may be a network entity 105 or a network entity 305 as described above. Figures 1 to 3 Examples of UE 115, UE 215 or UE 315 described.

[0108] like Figure 4 As shown, the network entity may generate an aggregated occupancy grid 425 for a 2-lane highway covering the geographic area 405. At a given point in time, the 2-lane highway may include a collection of UEs 415 (e.g., VUEs), and each UE 415 in the collection of UEs 415 may be equipped with a front sensor 420 (e.g., a radar sensor). Figure 3 As described, before the network entity can generate the aggregated occupancy grid 425, the network entity can send control information associated with generating the aggregated occupancy grid 425 to the set of UEs 415, and the control information can include an indication of the geographic area 405, the size of the cells 410 included in the geographic area 405, and the shape of the cells 410.

[0109] In some examples, the control information may include explicit indications of the geographic area 405, the size of the cells 410, and the shape of the cells 410. For example, the control information may include multiple coordinate sets 430 (e.g., global positioning system (GPS) coordinates), and each of the multiple coordinate sets 430 may be associated with a cell 410. The coordinate sets 430 may depict the shape of the associated cells 410, and the distances between the coordinate sets 430 may indicate the size of the associated cells 410. In one example, the shape of the cell 410 may be a rectangle. In this example, the coordinate set 430 associated with the cell 410 may include four coordinates 430 (e.g., one coordinate for each side of the rectangle). In this example, the control information may be signaled to the UE 415 as part of the application data. The cells 410 may collectively create the geographic area 405. In Figure 44, the size of the cells 410 is common, and the shape of the cells 410 is rectangular. The cells 410 together constitute a geographical area 405 having a rectangular shape. More specifically, the geographical area 405 is divided into 99 cells 410. The width of the geographical area 405 is 9 cells 410, and the height of the geographical area is 11 cells 410.

[0110] In another example, the control information may not include an explicit indication of the size of the cell 410 and the shape of the cell 410. In this example, the control information may include the boundary of the geographic area 405. As an example, the coordinate set 430 may be used to indicate the boundary of the geographic area 405. Additionally, the UE 415 may be pre-configured with the cell size and the cell shape. Upon receiving the control information, the UE 415 may perform a division of the geographic area 405 based on the cell size and the cell shape, and determine the coordinate set 430 for each cell 410. In another example, the UE 415 may be pre-configured (e.g., via RRC signaling) with a table including an index set. Each index in the index set may correspond to a corresponding cell size and cell shape. In the control information, the UE 415 may receive the index and determine the cell size and cell shape using the pre-configured table and index. In this example, the control information may be received as part of downlink control information (DCI), and the DCI may include a field for the index. The UE 415 may then perform a partitioning of the geographic area 405 based on cell size and cell shape, and determine a set of coordinates 430 for each cell 410 .

[0111] In another example, the control information may not include an explicit indication of the size of the geographic area 405, the cell 410, and the shape of the cell 410. In this example, the UE 415 may be pre-configured (e.g., via RRC signaling) with a table including a set of indices. Each index in the set of indices may correspond to a corresponding geographic area 405 (e.g., a boundary of the geographic area 405), a cell shape, and a cell size. In the control information, the UE 415 may receive the index and use the pre-configured table and index to determine the geographic area 405, the cell size, and the cell shape. In this example, the control information may be received as part of the DCI, and the DCI may include a field for the index. The UE 415 may then perform a division of the geographic area 405 based on the cell size and the cell shape, and determine a coordinate set 430 for each cell 410.

[0112] After learning geographic area 405, UEs 415 may determine whether their own geographic area (e.g., the geographic area covered by their own respective sensors 420) at least partially overlaps with geographic area 405. Figure 4As shown, at a given time, UE 415-a, UE 415-b, UE 415-c, and UE 415-d may determine that their own geographic areas at least partially overlap with geographic area 405. As such, UE 415-a, UE 415-b, UE 415-c, and UE 415-d may contribute information (e.g., occupancy grids) to assist a network entity in generating an aggregated occupancy grid 425.

[0113] Using their sensors 420, the UEs 415 may sense (e.g., during the same duration) whether each cell 410 in their respective geographic areas is occupied or unoccupied. As an example, a UE 415-d may sense that cells 410 at locations (3,4), (3,3), (3,2), (5,4), (6,4), and (7,4) in the geographic area 405 are occupied, and that the remaining cells 410 in its geographic area are unoccupied. Additionally, a UE 415-a may sense that cells 410 at locations (6,7), (5,7), (5,6), (5,5), (5,4), (3,4), (2,4), and (1,4) and the remaining cells 410 in its geographic area are unoccupied. As described with reference to FIG. Figure 2 As described above, each cell 410 may be mapped to REs in a one-to-one mapping manner. For an occupied cell 410, UE 415 may send signaling on the corresponding REs, and for an unoccupied cell 410, UE 415 may suppress sending signaling on the corresponding REs. If two or more UEs 415 sense that the same cell 410 is occupied, the two or more UEs 415 may send signaling on the same RE corresponding to the cell 410. For example, both UE 415-a and UE 415-d may send signaling on the RE corresponding to the cell at position (5, 4).

[0114] The network entity may monitor the REs and determine whether the REs are occupied or unoccupied based on signaling received through the REs. For example, the network entity may measure the energy level of each RE. If the energy level is above a threshold, the network entity may consider the cell 410 to be occupied. Alternatively, if the energy level is below a threshold, the network entity may consider the cell to be unoccupied. After sensing each of the REs, the network entity may generate an aggregated occupancy grid 425 for a two-lane highway within a given time.

[0115] Figure 5An example of an occupancy grid generation scheme 500 supporting dynamic aggregated occupancy grid generation according to one or more aspects of the present disclosure is illustrated. In some examples, the occupancy grid generation scheme 500 can implement aspects of the wireless communication system 100, the network architecture 200, the wireless communication system 300, and the occupancy grid generation scheme 400. For example, the occupancy grid generation scheme 500 may include a UE 515, which may be as described in reference Figures 1 to 4 Examples of UE 115, UE 215, UE 315 and UE 415 are described.

[0116] like Figure 3 As shown in FIG. 1 , UE 515 may be an example of a VUE and may communicate with one or more other UEs 515 ( Figure 3 505-a, 505-b, 505-c, 505-d, 505-e, 505-f, 505-g, 505-h, and 505-i.

[0117] As reference Figure 3As described, before the UE 515 can generate the occupancy grid 510, the UE 515 can receive control information associated with generating an aggregated occupancy grid from a network entity. In some examples, the control message may include an indication of the cell to RE mapping. The cell to RE mapping may be a one-to-one mapping. That is, a single cell 505 may be mapped to a single RE 530. As an example, the indication of the cell to RE mapping may include an indication of a starting symbol and a starting frequency range. Upon receiving the control information, the UE 515 may map each cell 505 to a RE 530. The mapping of the cell 505 may start at the upper left corner of the geographic area 525, and continue from left to right, and then move to the next row, etc. The mapping of the RE 515 may start at the starting symbol and the starting frequency range, and continue to the adjacent RE 515 in the same symbol, and then move to a different symbol (e.g., in a frequency-first manner). For example, cell 505-a, cell 505-b, cell 505-c, cell 505-d, cell 505-e, cell 505-f, cell 505-g, cell 505-h and cell 505-i can be mapped to RE 530-a, RE 530-b, RE 530-c, RE530-d, RE 530-e, RE 530-f, RE 530-g, RE 530-h and RE 530-i, respectively.

[0118] In another example, UE 515-a may be configured with a table including a set of indices, wherein each index in the set of indices corresponds to a RE to a cell mapping. In this example, the control information may include an index, and UE 515-a may determine the RE to cell mapping based on the index and the table. In some examples, the indication of the cell to RE mapping may be dynamic (e.g., indicated via downlink control information (DCI) or MAC control element (MAC-CE)) or semi-static (e.g., indicated via RRC signaling). In some examples, one or more REs 530 may be reserved for other signaling (e.g., SSB or CSI-RS). In this example, UE 115 may skip one or more REs 530 reserved for other signaling when executing the mapping scheme.

[0119] The UE 515 may determine (e.g., using one or more sensors) whether each cell 505 is unoccupied or occupied. If the UE 515 determines that the cell 505 is occupied, the UE 515 may send signaling on the RE 530 mapped to the cell 505. Alternatively, if the UE 515 determines that the cell 505 is unoccupied, the UE 515 may not send signaling on the RE 530 mapped to the cell 505. As an example, the UE 515 may sense that the cell 505-b, the cell 505-c, the cell 505-g, and the cell 505-h are occupied, while the remaining cells 505 are unoccupied. Thus, the UE 515 may send signaling on the RE 530-b, the RE 530-c, the RE 530-g, and the RE 530-h.

[0120] Figure 6 An example of a process flow 600 for supporting dynamic aggregated occupancy grid generation according to one or more aspects of the present disclosure is illustrated. In some examples, the process flow 600 may include aspects of the wireless communication system 100, the network architecture 200, the wireless communication system 300, the occupancy grid generation scheme 400, and the occupancy grid generation scheme 500. For example, the process flow 600 may include a network entity 605, which may be as described in reference Figure 1 and Figure 3 The process flow 600 may also include a UE 615, which may be as described in reference Figures 1 to 5 The examples of UE 115, UE 215, UE 315, UE 415 and UE 515 described above. The following alternative examples may be implemented in which some of the steps are performed in a different order than described or not performed at all. In some cases, the steps may include additional features not mentioned below, or other steps may be added.

[0121] At 610, the network entity 605 may send control information to the UE 615. The control information may indicate an occupied grid. The occupied grid may include a set of cells corresponding to a geographic area, and each cell may correspond to an RE in a set of REs. In some examples, the control information may include an indication of one or more of a geographic area, a shape of a cell in a set of cells, or a size of a cell. In some examples, additionally, the UE 615 may receive signaling (e.g., RRC signaling) indicating a table including a set of indexes, and each index in the set of indexes may correspond to one or more of a geographic area, a shape of a cell, or a size of a cell. In this example, the control information may include an index in the set of indexes.

[0122] In some examples, additionally or alternatively, the control information may include an indication of a mapping (e.g., one-to-one mapping) between a cell set and a RE set. As an example, the control information may include an indication of an RE and a starting symbol. The UE 615 may map a first cell in the cell set to an RE on a starting symbol, and map a second cell in the cell set to a second RE adjacent to the RE on the same starting symbol. Alternatively, the UE 615 may receive signaling (e.g., RRC signaling) indicating a table including an index set, and each index in the index set may correspond to a mapping. In this example, the control information may include an index in the index set. In some examples, one or more REs in the RE set may be reserved for different signaling. In this example, the UE 615 may suppress mapping a cell to one or more REs reserved for different signaling.

[0123] In some examples, the occupancy grid aggregation may occur dynamically. In such examples, additionally or alternatively, the control information may include an indication of a time slot for sending the occupancy information (e.g., a time slot including the group of UEs), or the UE 615 may receive a separate signaling indicating the time slot from the network entity 605 after the control information. In either case, the control information or signaling may be included in an uplink scheduling DCI (e.g., unicast or multicast), and the time slot indication may be indicated using the TRIV field of the uplink scheduling DCI. Alternatively, the occupancy grid aggregation may occur periodically. In this example, the UE 615 may receive a second control information indicating a configured grant (e.g., unicast or multicast). The configured grant may include an indication of a time slot that is repeated according to a certain periodicity. When the configured grant is activated, the UE 615 may perform the occupancy grid aggregation using the configured granted time slot. It may be assumed that the RE set used for aggregation (e.g., as indicated by the mapping) is the same for all periodically repeated time slots.

[0124] In some examples, UE 615 may receive control information according to a periodicity. In another example, UE 615 may send a request message for the configuration and receive control information based on sending the request message. UE 615 may operate according to the configuration until a second configuration associated with generating an occupancy grid using OTA aggregation is received, or until a counter that is incremented based on executing the configuration is reached.

[0125] At 620, UE 615 may receive first signaling indicating occupancy information of one or more cells in the set of cells from one or more sensors associated with UE 615. In some examples, the one or more sensors may include a lidar, a radar, or a camera. The occupancy information may inform UE 615 whether each of the one or more cells is occupied. In some examples, UE 615 may determine a second geographic area based on the range of the one or more sensors, and receive the first signaling based on the second geographic area being included in the geographic area of ​​the occupancy grid indicated in the control information.

[0126] At 625, UE 615 may send occupancy information to network entity 605. In one example, UE 615 may send signaling via REs corresponding to occupied cells for each of the one or more cells that are occupied. Additionally, UE 615 may refrain from transmitting on REs corresponding to unoccupied cells in the one or more cells.
