Description

Technical Field

[0001] The following relates to wireless communications, including configuration of a reconfigurable smart surface (RIS) to report events. Background Art

[0002] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcasting, etc. 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 that may be referred to as new radio (NR) systems. These systems may use 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 communication for a communication device, which may be referred to as a user equipment (UE).

[0003] In some systems, two or more devices can communicate with each other via a reflective surface (e.g., a device including one or more reflective surfaces, which may be referred to as a reconfigurable smart surface (RIS)). For example, a first device can send signaling to a reflective surface, and a second device can receive signaling reflected from the reflective surface. Summary of the invention

[0055] Some wireless communication systems may include one or more reconfigurable smart surfaces (RIS) (or wireless devices including RIS, or devices controlling the operation of RIS, which may sometimes be referred to as RIS controllers) that reflect signaling between other devices (e.g., between a network entity and a user equipment (UE), between two UEs). In some cases, the RIS may be an example of a reflective surface or a device including various reflective elements that may extend the coverage area of ​​the device, or may otherwise support a communication link between the device and one or more other devices. For example, the RIS may reflect signaling around a blockage so that two devices can communicate in any blockage situation. The RIS may be understood as a two-dimensional antenna array that includes or at least includes a set of reflective elements (e.g., individual scattering elements). Each reflective element may be configured according to a phase configuration so that the RIS reflects signals to or from a certain direction. Some RIS may be associated with a relatively large number of surface configurations (for different reflection directions), where different surface configurations correspond to different receive beams and reflected beam pairs at the RIS. In some cases, a device (e.g., a network entity, a UE) may send signaling to the RIS (e.g., to a controller of the RIS) to indicate the phase configuration of each of the set of reflective elements of the RIS. RIS can configure the surface according to the indicated phase configuration.

[0056] In addition to operating with relatively low power consumption, the RIS may have a relatively simple (e.g., low complexity) structure and may be relatively low cost. A device (e.g., a network entity, a UE) may configure the RIS using lower layer control signaling (e.g., layer 1 (e.g., physical layer (PHY)) or layer 2 (e.g., medium access control (MAC) layer) signaling). However, in some cases, such control signaling may be vulnerable to malicious attacks from unauthorized devices. In addition, some RIS may not be able to verify whether the received signal is from a valid source. For example, a malicious device may send an unauthorized communication configuration to the RIS so that the RIS is configured to be in an unexpected state (e.g., a state different from that associated with the communication configuration sent by an authorized network entity). The unauthorized communication configuration may shut down the RIS, thereby causing a communication interruption for any device using the RIS. In other examples, the unauthorized communication configuration may configure the RIS to reflect signals in a direction that causes congestion, interference, or reduced signal strength. Therefore, unauthorized and / or malicious control of the RIS may affect communications in a wireless communication system in various ways.

[0057] Therefore, the technology described herein supports the configuration of a status report sent by a RIS, wherein the status report indicates operational information associated with the RIS, which can provide early detection of unauthorized configurations of the RIS, thereby minimizing or avoiding the impact on communication efficiency and other issues. A device can monitor the status report received from the RIS to detect unauthorized configurations at the RIS. For example, a device (e.g., a network entity, a UE) can indicate one or more communication configurations to the RIS. In addition, the device can send control signaling to the RIS for indicating the status report configuration, such as a parameter set used by the RIS to send one or more status reports. The RIS can send a status report based on the status report configuration, wherein the status report indicates the current operational state of the RIS, the current configuration of the reflective element set of the RIS, the number of communication configurations received at the RIS, a list of communication configurations received at the RIS, or a combination thereof, as well as other examples. The device can receive the status report and can compare the operational information included in the status report with one or more communication configurations indicated by the device. If the operational information is inconsistent (e.g., matches, corresponds) with one or more communication configurations (e.g., the most recent communication configuration), the device can determine that the RIS has received or is operating according to an unauthorized configuration. In some examples, the device may indicate another communication configuration to return the RIS to the intended configuration. In other examples, the device may deactivate the RIS or perform other actions to avoid problems associated with unauthorized or malicious attacks on the RIS.

[0058] In addition, the described techniques support methods for verifying the validity of messages received at a device and a RIS. For example, a device may generate a signature to include in a status report configuration, thereby enabling the RIS to verify the status report configuration. The RIS may include a signature in a status report so that the device can verify the validity of the status report. Additionally, the RIS may send a status report according to a configured pattern (e.g., resource element pattern, identifier pattern), which may enable the device to verify the validity of the status report. In some cases, the RIS may send a status report based on a triggering event, such as a change in a measurement associated with receiving a control message from a device. For example, control signaling received by the RIS from a new angle of arrival (AoA) may indicate that the control signaling originated from an unauthorized device, and the RIS may be triggered to send a status report to the device.

[0059] Aspects of the disclosure are initially described in the context of wireless communication systems. Aspects of the disclosure are then discussed with reference to signaling diagrams and process flows. Aspects of the disclosure are further illustrated by apparatus diagrams, system diagrams, and flow diagrams relating to configuration of RIS reporting events, and are described with reference to these diagrams.

[0060] Figure 1 An example of a wireless communication system 100 that supports configuration of RIS reporting events according to one or more aspects of the present disclosure is shown. 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.

[0061] The network entities 105 may be spread over a geographic area to form a wireless communication system 100, and may be devices of different forms or with different capabilities. In various examples, the network entity 105 may be referred to as a network element, a mobile element, a radio access network (RAN) node, or a network device, among other names. In some examples, the network entity 105 and the UE 115 may wirelessly communicate via one or more communication links 125 (e.g., a radio frequency (RF) access link). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area), and the UE 115 and the network entity 105 may establish one or more communication links 125 in the area. The coverage area 110 may be an example of a geographic area on which the network entity 105 and the UE 115 may support transmission of signals according to one or more radio access technologies (RATs).

[0062] UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary, mobile, or both at different times. UEs 115 may be devices of different forms or with different capabilities. Figure 1 Some example UEs 115 are shown 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) communication.

[0063] As described herein, a node (which may be referred to as a network node, or a wireless node) of the wireless communication system 100 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 yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, with reference to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosures of UE 115, network entity 105, apparatus, device, computing system, or as a node, etc. For example, disclosures regarding UE 115 being configured to receive information from network entity 105 also disclose that the first node is configured to receive information from the second node.

[0064] In some examples, the network entities 105 may communicate with the core network 130 or 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 directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication links 120 (e.g., according to X2, Xn or other interface protocols). In some examples, the network entities 105 may communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, midhaul communication links 162 or fronthaul communication links 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 .

[0065] One or more network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, a NR base station, an access point, a radio transceiver, a Node B, an eNodeB (eNB), a next generation Node B, or a giga Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a Home NodeB, a Home eNodeB, or other suitable terminology). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) 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).

[0066] In some examples, the network entity 105 can be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture), which can be configured to utilize a protocol stack 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 central units (CUs) 160, distributed units (DUs) 165, radio units (RUs) 170, RAN intelligent controllers (RICs) 175 (e.g., near real-time RICs (near RT RICs), non-real-time RICs (non-RT RICs)), service management and orchestration (SMO) 180 systems, 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 disaggregated 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 disaggregated RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0067] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functions, depending on what functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed on 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 upper protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functions 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 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) functions and signaling, and each may 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 units (e.g., via one or more RUs 170). In some cases, the functional split between the CU 160 and the DU 165, or the functional split between the DU 165 and the RU 170 may be within the protocol layer (e.g., certain functions of the protocol layer may be performed by one of the CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, DU 165, or RU 170). The CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. The CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and the 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 according to interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 communicating via such communication links.

[0068] In a wireless communication system (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access can support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to the core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) can partially control 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 partially controlled by one or more CUs 160 associated with a donor network entity 105 (e.g., a 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 the DU 165 of the coupled IAB donor. 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., antennas 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 of an access network (e.g., downstream). In such a case, one or more components of the de-aggregated 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.

[0069] For example, an access network (AN) or RAN may include an access node (e.g., an IAB donor), communications between an IAB node 104, and one or more UEs 115. The donor IAB may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, an IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. An IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and the IAB node 104 may communicate via an F1 interface according to a protocol defining signaling messages (e.g., an F1 AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface, which may be an example of a portion of a backhaul link, and may communicate with other CUs 160 (e.g., CU 160 associated with an alternative IAB donor) via an Xn-C interface, which may be an example of a portion of a backhaul link.

[0070] The IAB node 104 may refer to a RAN node that provides IAB functions (e.g., access, wireless self-backhaul capabilities for UE 115). The DU 165 may act as a distributed scheduling node toward a child node associated with the IAB node 104, and the IAB-MT may act as a scheduling node toward a parent node associated with the IAB node 104. That is, the IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay transmissions for UEs through one or more other IAB nodes 104). Additionally or alternatively, the IAB node 104 may also be referred to as a parent node or child node to other IAB nodes 104, depending on the configuration of the relay chain or AN. Therefore, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104, and a DU interface (e.g., DU 165) may provide a Uu interface for the parent IAB node 104 to signal the child IAB node 104 or the UE 115.

[0071] For example, the IAB node 104 may be referred to as a parent node that supports communications for a child IAB node, or as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 having a wired or wireless connection (e.g., a backhaul communication link 120) to the core network 130, and may act as a parent node to the IAB node 104. For example, the DU 165 of the IAB donor may relay a transmission to the UE 115 through the IAB node 104, or may directly signal the transmission to the UE 115, or both. The CU 160 of the IAB donor may signal the establishment of a communication link to the IAB node 104 via the F1 interface, and the IAB node 104 may schedule a transmission (e.g., a transmission relayed from the IAB donor to the UE 115) through the DU 165. That is, data may be relayed to or from the IAB node 104 via signaling via the NR Uu interface of the MT to the IAB node 104. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .

[0072] 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 the configuration of RIS reporting events described herein. For example, additionally or alternatively, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may 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).

[0073] 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, as well as other examples. 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 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, as well as other examples, which may be implemented in various items such as appliances, or vehicles, meters, and other examples.

[0074] The UE 115 described herein may be able to communicate with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network devices, including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, such as Figure 1 shown.

[0075] UE 115 and network entity 105 can use resources associated with one or more carriers to communicate wirelessly with each other via one or more communication links 125 (e.g., access links). The term "carrier" can refer to a collection of RF spectrum resources with a specified physical layer structure to support communication links 125. For example, a carrier for 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-APro, NR). Each physical layer channel can carry acquisition signaling (e.g., synchronization signals, system information), control signaling to coordinate operations for the carrier, user data, or other signaling. The wireless communication system 100 can use carrier aggregation or multi-carrier operation to support communication with UE 115. UE 115 can be configured with multiple downlink component carriers and one or more uplink component carriers according to the carrier aggregation configuration. Carrier aggregation can be used with 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 a device and any portion (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 portion (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN that communicates with another device (e.g., directly or via one or more other network entities 105).

[0076] In some examples (e.g., in a carrier aggregation configuration), a carrier may also have acquisition signaling, or control signaling to coordinate operations for other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute Radio Frequency Channel Number (EARFCN)) and may be identified based on a channel raster for discovery by a UE 115. A carrier may be operated in a standalone mode, where initial acquisition and connection may be performed by a UE 115 via the carrier, or may be operated in a non-standalone mode, where a connection is anchored using a different carrier (e.g., with the same or different radio access technology).

[0077] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., fronthaul link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry either downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry both downlink communications and uplink communications (e.g., in TDD mode).

[0078] A carrier may be associated with a particular bandwidth of the RF spectrum, and in some examples, the carrier bandwidth may be referred to as the "system bandwidth" of the carrier or wireless communication system 100. For example, the carrier bandwidth may be one of a plurality of determined bandwidths of a carrier for a particular radio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 megahertz (MHz)). Devices of the wireless communication system 100 (e.g., base stations 105, UEs 115, or both) may have a hardware configuration that supports communication on a particular carrier bandwidth, or may be configured to support communication on one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include a base station 105 or UE 115 that supports simultaneous communication via carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate on a portion (e.g., subband, BWP) or all of the carrier bandwidth.

[0079] The signal waveform transmitted via the carrier wave may be composed of 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 techniques, a resource element may refer to a symbol period (e.g., the duration of a modulation symbol) and a subcarrier resource, in which case the symbol period and the subcarrier spacing are inversely proportional. 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., within the transmission duration) and a relatively high modulation scheme order may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of radio frequency spectrum resources, time resources, and spatial resources (e.g., spatial layers, beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0080] One or more digital schemes for a carrier may be supported, and the digital scheme may include a subcarrier spacing (Δf) and a cyclic prefix. A carrier may be divided into one or more BWPs with the same or different digital schemes. In some examples, a UE 115 may be configured with multiple BWPs. In some examples, a single BWP for a carrier may be active at a given time, and communications for a UE 115 may be limited to the one or more active BWPs.

[0081] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, for example, T s =1 / (Δf max ·N f ) seconds sampling period, for its Δf max It can indicate 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).

[0082] 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 (e.g., in the time domain) into subframes, and each subframe may be further divided into a 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 number of symbol periods (e.g., depending on the length of a cyclic prefix added in front of each symbol period). In some wireless communication systems 100, a 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 ) sampling period. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.

[0083] 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 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 the form of a burst of shortened TTIs (sTTIs)).

[0084] Physical channels can be multiplexed using carriers for communication according to various techniques. Physical control channels and physical data channels can be multiplexed via downlink carriers for signaling, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET)) for a physical control channel can be defined by a set of symbol periods and can extend across a system bandwidth or a subset of a system bandwidth of a carrier. One or more control regions (e.g., CORESETs) can be configured for a set of UEs 115. For example, one or more of UEs 115 can monitor or search a control region to obtain control information according to one or more search space sets, and each search space set can include one or more control channel candidates with one or more aggregation levels arranged in a cascaded manner. The aggregation level for a control channel candidate can refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with the coded information for a control information format with 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 .

[0085] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier) ​​used to distinguish adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which a logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, the cell may range from a smaller area (e.g., a structure, a subset of a structure) to a larger area. For example, a cell may be or include a building, a subset of a building, or an external space between or overlapping a geographic coverage area 110, etc.

[0086] A macro cell typically covers a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 115 with a service subscription to a network provider that supports the macro cell. A small cell may be associated with a lower-power network entity 105 (e.g., a lower-power base station 140) than a macro cell, and the small cell may operate using the same or different (e.g., licensed, unlicensed) frequency band as compared to the macro cell. A small cell may provide unrestricted access to a UE 115 with a service subscription to a network provider, or may provide restricted access to a UE 115 associated with a small cell (e.g., a UE 115 in a closed subscriber group (CSG), a UE 115 associated with a user in a residence or office). A network entity 105 may support one or more cells, and may also support communications via one or more cells using one or more component carriers.

[0087] In some examples, a carrier may support multiple cells, and different cells may be configured according to different protocol types (e.g., MTC, narrowband IoT (NB-IoT), enhanced mobile broadband (eMBB)) that may provide access to different types of devices.

[0088] 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 respective coverage areas 110 using the same or different radio access technologies.

[0089] The wireless communication system 100 may support synchronous or asynchronous operation. For synchronous operation, the network entities 105 (e.g., base stations 140) may have similar frame timing, and transmissions from different network entities 105 may be approximately aligned in time. For asynchronous operation, the base stations 105 may have different frame timing, and in some examples, transmissions from different base stations 105 may not be aligned in time. The techniques described herein may be used for either synchronous operation or asynchronous operation.

[0090] Some UEs 115 (e.g., MTC or IoT devices) may be low-cost or low-complexity devices and may provide automated communications between machines (e.g., machine-to-machine (M2M) communications). M2M communications or MTC may refer to data communications technology that allows devices to communicate with each other or a network entity 105 (e.g., a base station 140) without human intervention. In some examples, M2M communications or MTC may include communications from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents the information to a human 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, healthcare monitoring, wildlife monitoring, climate and geological event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based business billing.

[0091] Some UEs 115 may be configured to employ an operating mode that reduces power consumption, such as half-duplex communication (e.g., a mode that supports unidirectional communication via transmission or reception rather than concurrent transmission and reception). In some examples, half-duplex communication may be performed at a reduced peak rate. Other power conservation techniques for UE 115 include entering a power-saving deep sleep mode when not engaged in active communications, operating using limited bandwidth (e.g., according to narrowband communications), or a combination of these techniques. For example, some UEs 115 may be configured to operate using a narrowband protocol type that is associated with a defined portion or range (e.g., a set of subcarriers or resource blocks (RBs)) within a carrier, within a guard band of a carrier, or outside a carrier.

[0092] The wireless communication system 100 can be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 can be configured to support ultra-reliable low-latency communication (URLLC). UE 115 can be designed to support ultra-reliable, low-latency or critical functions. Ultra-reliable communication can include private communication or group communication, and can be supported by one or more services (such as push-to-talk, video or data). Support for ultra-reliable, low-latency functions can include prioritization of services, and such services can be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency can be used interchangeably herein.

[0093] In some examples, the 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 105). In some examples, one or more UEs 115 in such a group may be located outside of the coverage area 110 of the network entity 105, or may be otherwise 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.

[0094] 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, vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these. Vehicles can use signals to notify information related to traffic conditions, signal scheduling, weather, safety, emergencies, or any other information related to the V2X system. In some examples, vehicles in a 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, UR 170) using vehicle-to-network (V2N) communication, or perform both operations.

[0095] The core network 130 may provide user authentication, access permission, tracking, Internet Protocol (IP) connection, 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 to an external network or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management for 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 transmitted by user plane entities, which may provide IP address allocation and other functions. The user plane entity may be connected to an IP service 150 for one or more network operators. These IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0096] The wireless communication system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the very high frequency (UHF) region or decimeter band, due to its wavelength range from 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 penetrate buildings sufficiently for macro cells to provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter distances (e.g., less than 100 kilometers) compared to communications using lower frequencies and longer waves in the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.

[0097] The wireless communication system 100 may also operate in a super high frequency (SHF) region using a frequency band from 3 GHz to 30 GHz, also known as a centimeter band, or in an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz), also known as a millimeter band. In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between UE 115 and base station 170, and the EHF antennas of each device may be smaller and closer than UHF antennas. 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 atmospheric attenuation and shorter range than SHF or UHF transmissions. The technology disclosed herein may be used across transmissions using one or more different frequency regions, and the designated use of frequency bands across these frequency regions may vary by country or regulatory agency.

[0098] The wireless communication system 100 can utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 can use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to adopt license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed radio frequency spectrum bands, devices (such as network entities 105 and UE 115) can use carrier sensing for conflict detection and avoidance. In some examples, operations using unlicensed bands can be based on carrier aggregation configurations of component carriers in combination with operations using licensed bands (e.g., LAA). Operations using unlicensed spectrum can include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, as well as other examples.

[0099] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas, which may be used to employ techniques 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 within 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 in different geographic locations. The network entity 105 may include an antenna array having antenna ports of a set of rows and columns that the network entity 105 may 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. In addition, or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0100] The network entity 105 or UE 115 can use MIMO communication to utilize multipath signal propagation and increase spectrum efficiency by sending or receiving multiple signals via different spatial layers. Such a technology can be referred to as spatial multiplexing. For example, multiple signals can be sent by a transmitting device via different antennas or different combinations of antennas. Similarly, multiple signals can be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals can be referred to as a separate spatial stream and can carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers can be associated with different antenna ports for channel measurement and reporting. MIMO technology includes single-user MIMO (SU-MIMO) (for which multiple spatial layers are sent to the same receiving device) and multi-user MIMO (MU-MIMO) (for which multiple spatial layers are sent to multiple devices).

[0101] 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 transmitted 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 transmitted 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 the 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 transmitting device or the receiving device, or relative to some other orientation).

[0102] 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. Transmissions 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) a beam direction for later transmission or reception by the network entity 105.

[0103] Some signals, such as data signals associated with a particular receiving device, may be sent by a transmitting device (e.g., transmitting network entity 105, transmitting UE 115) along a single beam direction (e.g., a direction associated with a receiving device such as receiving network entity 105 or receiving UE 115). In some examples, the beam direction associated with transmission along a single beam direction may be determined based on signals that have been 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 having the highest signal quality or otherwise acceptable signal quality.

[0104] In some examples, transmissions by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may generate a combined beam for transmission (e.g., from network entity 105 to UE 115) using a combination of digital precoding or beamforming. 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 reference signals (e.g., cell-specific reference signals (CRS), channel state information reference signals (CSI-RS)) that may be precoded or unprecoded. 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 type codebook, a linear combination type codebook, a port selection type 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 employ similar techniques to send signals multiple times along different directions (e.g., for identifying a beam direction for subsequent transmission or reception by UE 115) or to send signals along a single direction (e.g., for sending data to a receiving device).

[0105] 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), the receiving device (e.g., UE 115) can perform receiving operations according to multiple receiving configurations (e.g., directional listening). For example, the receiving device can perform reception according to multiple receiving directions by receiving via different antenna subarrays, by processing received signals according to different antenna subarrays, by 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 by processing received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which can be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device can 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 otherwise acceptable signal quality based on listening according to multiple beam directions).

[0106] The wireless communication system 100 can be a packet-based network operated according to a layered protocol stack. In the user plane, the communication of the bearer or PDCP layer can be IP-based. The RLC layer can perform packet segmentation and reorganization to transmit via logical channels. The MAC layer can perform priority processing and multiplexing of logical channels to transport channels. The MAC layer can also implement error detection technology, error correction technology, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer can provide the establishment, configuration and maintenance of the RRC connection (which supports radio bearers for user plane data) between the UE 115 and the network entity 105 or the core network 130. The PHY layer can map the transport channel to the physical channel.

[0107] In some examples, the wireless communication system 100 can employ massive MIMO (e.g., 5G massive MIMO) to increase the achievable throughput between two communicating devices, and can extend the coverage by one or more active antenna units or one or more passive reflective surfaces (e.g., RIS), or any combination thereof. For example, devices in the wireless communication system 100 can achieve relatively high beamforming gain by using active antenna units (e.g., devices capable of supporting active antenna units, such as network entities 105, UEs 115, relay nodes, smart repeaters, etc.). In some aspects, such active antenna units can be associated with the use of separate RF chains for each antenna port. Such a system may experience a significant increase in power consumption due to the use of active antenna units.

[0108] Some systems (e.g., wireless communication system 100) may use one or more auxiliary devices, such as one or more RIS, in addition to or as an alternative to deploying additional active antenna units to extend coverage (e.g., 5G coverage) with negligible or relatively small increase in power consumption (e.g., compared to active antenna units). For example, some systems may utilize passive MIMO as an alternative to active antenna units. A RIS may be a nearly passive device that is capable of reflecting an impinging or incident wave to a desired location or in a desired direction.

[0109] For example, the wireless communication system 100 may include one or more RISs to extend wireless communication coverage around or due to congestion between devices (e.g., between a network entity 105 and a UE 115, between two UEs 115). For example, the network entity 105 and the UE 115 may attempt to establish a communication link with each other using beamforming techniques and via an auxiliary device controlled by an auxiliary node. Such an auxiliary device may include or be an example of a RIS, and such an auxiliary node may include or be an example of a central unit (CU) or some other device capable of CU functionality (e.g., any device capable of wirelessly transmitting or receiving or capable of configuring or otherwise controlling one or more auxiliary devices).

[0110] A RIS (which may sometimes be referred to as a smart surface, a passive access point, or other similar terms) may extend the coverage area of ​​a device, or may support a communication link between devices by reflecting beams in one or more target directions. For example, a RIS may reflect beams around obstacles so that devices can communicate in the presence of obstacles. In some cases, a RIS may consume relatively low power to reflect transmissions (e.g., compared to a device that uses an active antenna unit to transmit a beamforming signal). That is, the RIS may passively reflect beams according to a configured (i.e., target) direction. The network entity 105 or the UE 115 may configure (e.g., control) the RIS (e.g., through an auxiliary node) to reflect transmissions according to the configured direction. The RIS may include a set of reflective elements (e.g., N reflective elements), each of which may be configured according to a phase configuration so that the RIS reflects signals to or from the configured direction. For example, the RIS may include a control unit (also referred to herein as a RIS controller) that may receive signaling from a device (e.g., from the network entity 105, from the UE 115) and set the phase configuration of each reflective element. In some cases, the RIS may include a two-dimensional reflective element and may reflect one or more beams (eg, in one or more directions (eg, symmetric directions)).

[0111] In some cases, the device may configure N reflective elements of the RIS to improve a channel between the device and another device. For example, the network entity 105 may configure N reflective elements of the RIS to improve a channel between the network entity 105 and the UE 115. In some cases, the channel between the network entity 105 and the UE 115 via the RIS having N reflective elements may be based on one or more communication parameters, such as element spacing of the reflective elements, AoA of a signal from the network entity 105 to the RIS, wavelength of the signal, etc., as well as other examples. Thus, the network entity 105 may configure the RIS (e.g., may configure N reflective elements) using a communication configuration based on one or more communication parameters, for example, to increase the signal strength between the network entity 105 and the UE 115. For example, the network entity 105 may send signaling to the RIS indicating a communication configuration so that the RIS reflects a signal in a target direction according to the communication configuration. In some examples, the communication configuration may correspond to a phase configuration of one or more reflective elements in a set of RIS reflective elements. For example, for each reflective element N, the network entity 105 may determine a respective phase configuration. Alternatively, the network entity 105 may determine the phase configuration for each subset of reflective elements of the set of reflective elements.

[0112] According to the techniques described herein, a device configuring a RIS may configure one or more status reports to be sent by the RIS. A device (e.g., a network entity 105 or a UE 115) may send a message to the RIS indicating a status report configuration. The status report configuration may include one or more parameters to be used by the RIS to send one or more status reports. For example, the one or more parameters may include the number of status reports to be sent, the status report periodicity, one or more operating parameters associated with the current operation of the RIS to be included in the status report, a triggering event for sending the status report, a bitmap for indicating a mapping between a set of communication configurations and a set of symmetric keys, or a combination thereof. The one or more operating parameters may include the current operating state of the RIS, the current configuration of multiple reflective elements of the RIS, the number of communication configurations received at the RIS, a list of communication configurations received at the RIS, or a combination thereof. The RIS may send a status report based on the status report configuration. The device may monitor the status report received from the RIS to detect unauthorized configurations at the RIS. For example, the device may compare the operating information indicated in the status report with the communication configuration sent by the device to determine whether the RIS has received any communication configurations from an illegal device.

[0113] Figure 2 An example of a wireless communication system 200 that supports configuration of RIS reporting events according to one or more aspects of the present disclosure is shown. The wireless communication system 200 may implement aspects of the wireless communication system 100, or may be implemented to implement aspects of the wireless communication system 100. For example, the wireless communication system 200 may include a network entity 105-a, a UE 115-a, and a UE 115-b, which may be reference Figure 1 In addition, the wireless communication system 200 may include a RIS 205 having a set of reflective elements 210. Although the RIS 205 includes nine reflective elements 210 shown, the RIS 205 may include a different number of reflective elements 210, such as more than nine reflective elements 210 (e.g., one thousand reflective elements 210, four thousand reflective elements 210).

[0114] The wireless communication system 200 may support MIMO technology, which in turn may support an increase in throughput (e.g., compared to a wireless communication system that does not support MIMO technology). In some cases, in order to support MIMO technology, devices in the wireless communication system 200 (e.g., network entity 105-a, UE 115) may use active antenna units to communicate via beams 215 with relatively high beamforming gain. This may include configuring a separate RF chain for each antenna port. However, due to the use of active antenna units, this approach may be associated with a significant increase in power consumption. Therefore, the wireless communication system 200 may deploy RIS205 to extend coverage (e.g., around obstructions) with negligible power consumption (e.g., compared to active antenna units). For example, RIS205 may be a nearly passive device capable of reflecting an impinging wave or an incident wave to a desired location or desired direction.

[0115] RIS 205 can be similar to the functionality of a reflector or other type of reflective surface in its ability to reflect an incident beam or wave (e.g., light waves, radio waves), but the difference is that RIS 205 can include one or more components that can control or specify the manner in which the incident beam or wave is reflected (such that the angle of incidence can be different from the angle of reflection) or can control or specify the shape of the reflected beam or wave (e.g., via energy focusing or via constructive interference or destructive interference to zero the energy, respectively), or both. For example, the set of reflective elements 210 included in RIS 205 can each have a controllable delay, phase, or polarization, or any combination thereof. Therefore, each reflective element 210 can be controlled or configured to direct the reflection of an incident beam or wave or control the shape of a reflected beam or wave. RIS205 can be an example of a software-controlled metasurface, a configurable reflective surface, a reflective smart surface, a configurable smart surface, or other terms, or can be otherwise referred to as a software-controlled metasurface, a configurable reflective surface, a configurable smart surface, or other terms, and RIS205 can sometimes be a metal surface (e.g., a copper surface) that includes, among other examples, a certain number of reflective elements 210.

[0116] In some aspects, the RIS CU 220 may be coupled to the RIS 205 via hardware (e.g., via a fiber optic cable). In some other aspects, the RIS CU 220 may be non-co-located with the RIS 205, and the RIS 205 may be configured via over-the-air signaling. In some aspects, the RIS CU 220 may have both sending and receiving capabilities. The RIS CU 220 may also be referred to as a RIS controller, and may be an example of a CU, a node, or any device with CU capabilities. The RIS CU 220 may control the RIS 205 by configuring one or more reflection characteristics of the RIS 205 to control the reflection direction from the RIS 205. For example, the RIS CU 220 may control or configure each reflective element 210 to control the reflection mode of the incident beam or wave, or to control the shape of the reflected beam or wave. In some cases, another device (e.g., different from RIS CU 220), such as a UE (e.g., UE 115) or a network entity (e.g., network entity 105-a) can configure or control RIS CU 220 (so that the device can effectively configure or control the reflection direction of RIS 205).

[0117] For example, the RIS 205 (e.g., the RIS CU 220) may receive a communication configuration from another device such as the network entity 105-a or the UE 115. The communication configuration may be understood as a configuration for the RIS 205, for example, a configuration for the reflective element set 210 for the RIS 205. The device may select a communication configuration that implements a desired shape or reflection direction of a beam (i.e., a signal) transmitted in the direction of the RIS 205. In some aspects, the communication configuration of the RIS 205 may be associated with a receive beam, such as a directional beam or configuration for directional "reception" of signaling, and a reflective beam, such as a directional beam or configuration for directional reflection of signaling. For example, the communication configuration may indicate a beam associated with a transmission to be reflected by the RIS 205 (e.g., to a receiving device). Additionally or alternatively, the communication configuration may indicate an index associated with the beam, or may indicate a sum associated with an AoA associated with the beam (e.g., at the RIS 205) and a departure angle associated with the beam (e.g., from the RIS 205). In some examples, the communication configuration may indicate a respective configuration for each of one or more individual reflective elements 210, may indicate one or more respective configurations for each of one or more subsets of reflective elements 210, or may indicate a configuration for a set of reflective elements 210. In any case, RIS 205 (e.g., RIS CU 220) may configure reflective elements 210 according to the received communication configuration so that a signal (e.g., a receive beam) received at RIS 205 is reflected in a predetermined direction (e.g., as a reflected beam).

[0118] As shown in the wireless communication system 200, for example, by reflecting communications from the network entity 105-a (e.g., directly from the network entity 105-a to the RIS 205) to the UE 115-a (e.g., directly from the RIS 205 to the UE 115-a) via the beam 230, the RIS 205 can support a communication link between the network entity 105-a and the UE 115-a. For example, the network entity 105-a can send a message transmission (e.g., a control signal) indicating the configuration of the RIS 205 to the RIS CU 220 to achieve an appropriate reflection direction of the beam 230, and the RIS CU 220 can configure the RIS 205 accordingly. In some cases, the RIS 205 can reflect a beam (e.g., beam 230) according to a direction based on the phase configuration of each reflective element 210 of the RIS 205. For example, the RIS 205 can set the phase configuration of each reflective element 210 to adjust the departure angle of the beam reflected by the RIS 205. Furthermore, although described herein as a "receive" beam, a receive beam associated with the configuration of RIS 205 may receive as part of a reflection (as opposed to, for example, as part of a decode).

[0119] In some scenarios, a malicious device may attempt to control RIS205 into an unauthorized configuration or state. Figure 2 As shown, the network entity 105-a and the UE 115-a can be examples of authorized (e.g., valid, legal) devices, so that the communication configuration sent to the RIS 205 (e.g., to the RIS CU 220) can be considered as an authorized (e.g., valid, legal) configuration. Specifically, the network entity 105-a can send downlink control signaling indicating one or more communication configurations (e.g., authorized communication configurations) to the RIS 205 via the beam 215-a, for example, to configure the RIS 205 to support communication between the network entity 105-a and the UE 115-a. In order to enable the RIS 205 to decode the control signaling and implement a configuration with relatively low latency, the network entity 105-a can utilize L1 / L2 signaling (such as physical layer signaling or MAC layer signaling) for the transmission of the communication configuration. However, due to its relatively simple structure, the L1 / L2 signaling may be easily copied by malicious devices, and the RIS 205 may not be able to distinguish between authorized configurations and unauthorized configurations.

[0120] For example, UE 115-b may be a malicious (e.g., unauthorized, invalid, illegal) device. UE 115-b may send an unauthorized communication configuration to RIS 205 via beam 215-c. If RIS 205 configures itself based on the unauthorized communication configuration, RIS 205 may no longer be able to reflect beam 230 in the direction of UE 115-a. For example, the unauthorized communication configuration may configure RIS 205 to a different direction, causing beam 230 to experience congestion or interference, or causing the signal sent via beam 230 to be relatively weak (e.g., compared to an authorized configuration). Additionally or alternatively, the unauthorized communication configuration may configure RIS 205 to switch to an off state.

[0121] To avoid or mitigate such attacks, the RIS 205 (e.g., RIS CU 220) may be configured to send one or more status reports to a control device such as a network entity 105-a or a UE 115 (e.g., UE 115-a). The control device may be the same device that sends the communication configuration to the RIS 205, or may be different from the device that sends the communication configuration to the RIS 205. The status report may indicate information related to operations on the RIS 205, such as a list of configurations received or implemented on the RIS 205 within a given time period. The control device may analyze the operational information in the status report to determine whether the RIS 205 has received unauthorized communications from a malicious device. In some cases, the control device may compare the list of configurations received by the RIS 205 with a record (e.g., history) of authorized configurations (e.g., sent by the control device) to identify any mismatches. For example, if the list of configurations received by the RIS 205 includes additional configurations, such as configurations that are not included in the record of authorized configurations, the control device may determine that the additional configurations are unauthorized (e.g., originating from an unauthorized device). Thus, the status reports sent by RIS 205 enable the control device to monitor attacks on RIS 205 .

[0122] exist Figure 2In an example of the embodiment, the network entity 105-a may send control signaling (e.g., one or more control messages) to the RIS 205 via the beam 215-a to indicate one or more communication configurations of the RIS 205. The network entity 105-a may additionally send a message to the RIS 205 to indicate a status report configuration to configure a reporting event for the RIS 205. A reporting event may refer to a transmission of a status report by the RIS 205. The message may include or be an example of control signaling, such as L1, L2, or L3 (e.g., PHY layer, MAC layer, or radio resource control (RRC) layer) signaling (e.g., physical downlink shared channel (PDSCH) message, physical downlink control channel (PDCCH) message, downlink control information (DCI), MAC control element (MAC-CE), RRC message).

[0123] Although the examples described herein are discussed with reference to a network entity 105-a that sends control signaling for indicating a communication configuration and a status report configuration, it is to be understood that any device can configure the RIS 205. For example, the UE 115-a can send control signaling for indicating one or more communication configurations and status report configurations to the RIS 205. In such an example, the UE 115-a can communicate with the RIS 205 using uplink signaling or sidelink signaling. That is, the control signaling sent by the UE 115-a can be an example of uplink control information (UCI), sidelink control information (SCI), a physical sidelink shared channel (PSSCH) message, a physical sidelink control channel (PSCCH), etc.

[0124] The status report configuration may include a set of parameters for the RIS 205 to use in sending one or more status reports related to the operation of the RIS 205. The set of parameters may include transmission parameters for the one or more status reports, such as a period, a set of resources (e.g., time resources, frequency resources, space resources), etc. In some cases, the set of parameters may include a number of status reports to be sent by the RIS 205, for example, within a specified time period. The time period may be indicated by a time duration, an initial start time, an end time, a number of reporting events, or a combination thereof.

[0125] Additionally or alternatively, the parameter set may indicate information (e.g., operational information, operational parameters) to be included in the status report, such as the current operational state of the RIS 205, one or more past operational states of the RIS 205, the current configuration of the RIS 205 (e.g., the current configuration of the reflective element set 210), one or more past configurations of the RIS 205, the number of all or a subset of communication configurations received at the RIS 205 (e.g., within an indicated time period), a list of all or a subset of communication configurations received at the RIS 205 (e.g., within a specified time period), or a combination thereof. For example, the status report may indicate whether the current operation of the RIS 205 corresponds to the communication configuration sent by the network entity 105-a. In some examples, the indicated time period may be defined as a time period between reporting events. For example, the RIS 205 may be configured to report the number of communication configurations received since the RIS 205 sent a previous status report. In other words, the RIS 205 may receive the number of communication configurations between two reporting events, for example, during a time period starting after the RIS 205 sent a previous status report and ending when the RIS 205 sends a current status report.

[0126] The status report may have a report length in bits, for example, may include the number of bits used to indicate operational information, where the number of bits may depend on the type of signaling used for the status report. For example, RIS205 may send the status report as an L1 / L2 signal (e.g., via the PHY / MAC layer), which may be associated with a limited number of bits (e.g., 3 bits). RIS205 may modify the operational information to align with the limited number of bits. For example, RIS205 may be configured to report the number of communication configurations received within a given time period (which may be indicated by a parameter set), but the number of communication configurations received may be greater than the number of bits available for the status report. In this case, RIS205 may apply a modulo operation to the operational information based on the limited number of bits, as shown in Equation 1 below.

[0127] C mod(r b )=x (1)

[0128] In Formula 1, C represents the number of configurations received at RIS 205, r represents the number of reports sent by RIS 205 between which the number of configurations are received, b represents a finite number of bits, and x represents a value indicated in the status report. That is, x is a value representing operational information to be reported by RIS 205. By way of example, if RIS 205 receives nine communication configurations between the transmission of a first status report and a second status report (e.g., between the two status reports), and there are three bits available to send a status report, then x may be equal to 1, and RIS 205 may indicate a value of one (1) in the status report.

[0129] In some examples, the parameter set may include an indication of a triggering event (e.g., an event that triggers RIS 205 to send a status report), such that RIS 205 sends a status report when the triggering event occurs. The triggering event may be, for example, a change in a channel condition between network entity 105-a and RIS 205, a change in a measurement associated with reception of a beam at RIS 205, etc. Additionally or alternatively, the triggering event may indicate a number of status reports to be sent by RIS 205 within a specified time period. Here, RIS 205 may begin sending a first status report of the number of status reports based on the indicated time period.

[0130] The measurements to be monitored by the RIS 205 may include AoA, reference signal received power (RSRP), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR), etc. The RIS 205 may perform measurements on signals received at the RIS 205 over time, and may send a status report when one or more of the measurements changes. For example, the RIS 205 may perform measurements on control messages received from the network entity 105-a, such as control messages indicating a communication configuration. As an example, the RIS 205 may expect to receive communications from the network entity 105-a via beam 215-a, which may be associated with an AoA on the RIS 205 due to the fixed nature of the network entity 105-a. If the RIS 205 receives signaling (e.g., communication configuration) via a beam associated with a different AoA (e.g., beam 215-c from UE 115-b), the RIS 205 may be triggered to send a status report to the network entity 105-a. The network entity 105 - a may receive a status report indicating that the RIS 205 received an unauthorized communication configuration.

[0131] In some examples, a device other than the network entity 105-a may be configured to receive a status report from the RIS 205. For example, a UE 115 served by the RIS 205 (e.g., a UE 115 receiving signaling from the RIS 205, such as a UE 115 communicating with the network communication entity 105-a through the RIS 205) may be configured to collect status reports from the RIS 205, and in some cases, forward the status reports to the network entity 105-a. For example, the network entity 105-a may send a message to the UE 115-a via the beam 215-b, wherein the message indicates a configuration associated with a status report to be sent by the RIS 205. The configuration may enable the UE 115-a to distinguish whether a transmission received from the RIS 205 is a reflected signal originating from the network entity 105-a or a status report originating from the RIS 205. That is, if the transmission is consistent with the configuration, the UE 115-a may recognize that the transmission received from the RIS 205 is a status report. For example, the UE 115-a may expect the RIS 205 to send status reports in a format specified by the configuration. Additionally, the configuration may instruct the UE 115-a to forward (eg, relay) received status reports to the network entity 105-a.

[0132] In such an example, UE 115-a may be further configured to trigger RIS 205 to send a status report. Here, UE 115-a may perform measurements associated with receiving one or more signals (e.g., control signals) at RIS 205. If UE 115-a determines that a change in one or more measurement values ​​has occurred, UE 115-a may trigger a status report by sending a control message to RIS 205, the control message being used to instruct RIS 205 to send a status report to UE 115-a. Thus, in some cases, a triggering event indicated in a status reporting configuration of RIS 205 may include receiving a triggering control message at RIS 205.

[0133] RIS205 may send status reports according to a timing based on the type of signaling associated with the status report, for example, in addition to any periodicity indicated by the status report configuration. For example, if the status report uses L1 / L2 signaling, RIS205 may send status reports relatively frequently (e.g., every 20 milliseconds). Such lower layer signaling may also be associated with reduced overhead. In contrast, higher layer signaling may be associated with a relatively large reporting period (e.g., once every 10 seconds). However, higher layer signaling may support encryption of status reports, while lower layer signaling may not. That is, lower layer signaling may be vulnerable to imitation (e.g., attack) by malicious devices (e.g., UE 115-b). For example, UE 115-b may create a false status report that appears to come from RIS205. For example, by sending a false (e.g., invalid, illegal) status report to network entity 105-a, UE 115-b may mislead network entity 105-a to cover up or hide any malicious activity of UE 115-b at RIS205.

[0134] To avoid or mitigate false status reports, the network entity 105-a can configure a transmission mode for the status reports sent by the RIS205, wherein the transmission mode acts as an encryption method. That is, as long as the status report is sent according to the configured transmission mode, the network entity 105-a can verify that the received status report is from the RIS205. In a first example, the network entity 105-a can determine a resource element pattern of resources (e.g., time resources and frequency resources) on which the RIS205 sends one or more status reports. The resource element pattern may include a random (or pseudo-random) set of resources. In some cases, the resource element pattern may include or be an example of a frequency hopping pattern. The RIS205 can send each status report in a respective subset of resources of the random set of resources according to the resource element pattern.

[0135] In a second example, the network entity 105-a may determine an RNTI pattern for a set of radio network temporary identifiers (RNTIs) associated with status reports sent by the RIS 205. The RIS 205 may select a corresponding RNTI from the set of RNTIs based on the RNTI pattern to include in each sent status report. The RNTI pattern may be time-dependent, such that the RIS 205 may switch the RNTIs included in the status report based on a time-based pattern. That is, the RNTI selected by the RIS 205 to be included in the status report may change periodically over time, for example, based on a timer, a time domain resource corresponding to the status report, etc.

[0136] In some examples, RIS205 can be pre-configured with a resource element pattern, an RNTI pattern, or both. In other examples, the network entity 105-a can send a mode configuration message indicating a resource element pattern, an RNTI pattern (e.g., a set of RNTIs, an RNTI pattern, a timer associated with an RNTI pattern, a set of time domain resources associated with an RNTI pattern, or a combination thereof), or both. Here, the mode configuration message can be sent via higher layer signaling (e.g., RRC signaling) and can be encrypted by the network entity 105-a to prevent any malicious device (e.g., UE 115-b) from acquiring the pattern. Additionally or alternatively, the network entity 105-a can dynamically update the resource element pattern or RNTI pattern over time, for example, by sending subsequent mode configuration messages to indicate an updated transmission mode.

[0137] In some cases, the network entity 105-a can further support secure communications with the RIS 205 by appending an authentication signature (e.g., a PHY layer digital signature) to the communication configuration of the RIS 205, which can be based on or associated with a private key (e.g., a symmetric key). In some examples, the network entity 105-a can generate an authentication signature based on the configuration of the RIS 205 (e.g., the communication configuration), such as the phase configuration (e.g., beam weight) of one or more reflective elements 210 of the RIS 205. The authentication signature can include or be an example of a sequence (e.g., a bit sequence), a commitment value (e.g., associated with a commitment key), etc. The network entity 105-a can include the authentication signature within control signaling (e.g., indicating a communication configuration, a status report configuration, or both) sent to the RIS 205. The RIS 205 can verify that the control signaling is from an authorized source (e.g., from the network entity 105-a) based on the authentication signature associated with the phase configuration of the reflective element 210 of the RIS 205. That is, if the control message includes an authentication signature corresponding to a phase configuration that is not currently implemented at RIS 205 , RIS 205 may determine that the control message is invalid and may discard the control message.

[0138] In some examples, the network entity 105-a may determine a bitmap for indicating a relationship (e.g., a mapping) between one or more communication configurations and one or more authentication signatures. For example, for a large number of communication configurations and authentication signatures, the bitmap may indicate that a first communication configuration corresponds to a first authentication signature, a second communication configuration corresponds to a second authentication signature, and so on. The network entity 105-a may indicate the bitmap to the RIS 205 as part of a status report configuration (e.g., the bitmap may be an example of a parameter of the parameter set). For example, when sending control signaling indicating a communication configuration to the RIS 205, the network entity 105-a may include an authentication signature corresponding to the indicated communication configuration in the control signaling based on the bitmap. The RIS 205 may verify the authenticity of the control signaling based on the authentication signature and the bitmap. For example, the RIS 205 may check (e.g., using a bitmap) whether the authentication signature corresponds to the indicated communication configuration. If the authentication signature and the indicated communication configuration do not correspond to each other based on the bitmap, the RIS 205 may determine that the control signaling is unauthorized.

[0139] If the RIS 205 receives the authentication signature as part of a valid (e.g., authorized) control message, the RIS 205 may include the authentication signature in a status report sent to the network entity 105-a to indicate that the status report is from the RIS 205 (e.g., not from an unauthorized device). For example, the RIS 205 may send a status report indicating an authentication signature associated with the current operation (or configuration) of the RIS 205. The authentication signature may be based on a bitmap indicated in the status report configuration.

[0140] After receiving the status report from the RIS 205, the network entity 105-a may verify the status report and the operational information indicated by the status report. For example, the network entity 105-a may verify that the status report originated from the RIS 205 by checking whether a signature included in the status report matches a signature generated by the network entity 105-a and included in a control message to the RIS 205. The network entity 105-a may compare the operational information with information associated with the RIS 205 and known to the network entity 105-a to identify whether the RIS 205 has been tampered with by a malicious device (e.g., UE 115-b). For example, the network entity 105-a may determine whether the number of communication configurations received at the RIS 205 and indicated in the status report is the same as the number of configurations sent by the network entity 105-a. Additionally or alternatively, the network entity 105-a may determine whether the list of communication configurations received at the RIS 205 (and indicated in the status report) includes only communication configurations sent by the network entity 105-a, e.g., without including any additional communication configurations from other devices (e.g., UE 115-b).

[0141] In some cases, if the network entity 105-a determines that the RIS 205 has been compromised by a malicious device (e.g., has received an unauthorized communication configuration), the network entity 105-a may assume that the RIS 205 is controlled by the malicious device. The network entity 105-a may send a report to the network operator to indicate that the RIS 205 has been compromised. Additionally or alternatively, the network entity 105-a may temporarily shut down the RIS 205. For example, the network entity 105-a may send a control message to the RIS 205 to indicate that the RIS 205 will transition to a closed state. In some cases, the network entity 105-a may send the control message using encrypted or other secure signaling, such as higher layer signaling (e.g., RRC messages).

[0142] Figure 3 An example of a signaling diagram 300 that supports configuration of RIS reporting events according to one or more aspects of the present disclosure is shown. The signaling diagram 300 may implement or be implemented to implement aspects of the wireless communication system 100 or the wireless communication system 200. For example, the signaling diagram 300 may show communication between a device 303 and a RIS CU 305 to configure a reporting event on a RIS 307 controlled by the RIS CU 305. The signaling diagram 300 may also include a device 309, which may be a reference Figure 2 RIS CU 305 and RIS 307 may be examples of respective devices described herein. In some aspects, RIS 307 may operate with RIS CU 305, or RIS 307 may operate without RIS CU 305. That is, RIS 307 may include functions and components configured to perform the described techniques (e.g., without RIS CU 305).

[0143] Device 303 may include or refer to Figure 1 and 2 An example of a network entity or UE is described. Figure 3 In the example of , device 303 can send downlink messages to RIS CU 305 and can receive uplink messages from RIS CU 305, although other types and message combinations can utilize the techniques described herein. For example, if device 303 is an example of a UE, device 303 can communicate with RIS CU 305 via sidelink communication.

[0144] As reference Figure 2As described, the device 303 may send a status report configuration 310 to the RIS CU 305 to indicate a set of parameters for sending one or more status reports associated with the operation of the RIS 307. The set of parameters may include the number of status reports to be sent by the RIS CU 305, the status report periodicity, the triggering event for sending the status report, a bitmap for indicating a mapping between a communication configuration set (e.g., RIS configuration) and a symmetric key set, or a combination thereof. Additionally or alternatively, the set of parameters may include one or more operational parameters associated with the current operation of the RIS 307 to be included in the status report, such as the current operational state of the RIS 307 (e.g., on state, off state), the current configuration of the plurality of reflective elements of the RIS 307 (e.g., the current communication configuration), the number of configurations received at the RIS 307 (e.g., within an indicated time period), a list of RIS configurations received at the RIS 307 (e.g., within an indicated time period), or a combination thereof.

[0145] exist Figure 3 In the example of , RIS CU 305 may be configured (via status report configuration 310) to send a first status report, such as status report 315-a, to device 303 indicating the current operating state of RIS 307. The status report configuration may further indicate that RIS CU 305 is to send additional status reports 315, and each additional status report will include a list of RIS configurations (e.g., RIS configurations 325) received at RIS 307 between two reporting events. For example, a first reporting event of the two reporting events may correspond to the transmission of a first status report (e.g., status report 315-a) by RIS CU 305. A second reporting event may correspond to the transmission of a second status report (e.g., status report 315-b) by RIS CU 305. In other words, RIS CU 305 may be configured to send status report 315-b after the transmission of status report 315-a by RIS CU 305, which status report 315-b indicates all RIS configurations received at RIS CU 305. In addition, the third reporting event may correspond to the transmission of a third status report (e.g., status report 315-c); thus, in status report 315-c, RIS CU 305 may indicate a list of RIS configurations received by RIS CU 305 after receipt of status report 315-b.

[0146] In certain aspects, status report configuration 310 may include a bitmap indicating a mapping between a set of one or more RIS configurations and a set of signatures (eg, bit sequences), which may be based on or associated with a set of symmetric keys.

[0147] RIS CU 305 may send a status report 315-a to device 303 according to status report configuration 310. RIS CU 305 may indicate in status report 315-a the current operating state of RIS 307. For example, RIS CU 305 may indicate that RIS 307 is operating in an on state.

[0148] The device 303 may send a message (e.g., a control message) indicating a mode configuration 320 to the RIS CU 305, indicating one or more transmission modes according to which the RIS CU 305 sends subsequent status reports. For example, the mode configuration 320 may indicate a resource element pattern, an RNTI pattern, and an RNTI set associated with the RNTI pattern. The RNTI pattern may include or be indicated by a time domain resource set corresponding to the RNTI set.

[0149] Device 303 may send a first control message indicating RIS configuration 325-a to RIS CU 305. The first control message may also include a first signature associated with RIS configuration 325-a. RIS CU 305 may verify that the first control message is a valid message (e.g., originating from an authorized device, such as device 303) based on a mapping between the first signature and the RIS configuration 325-a indicated by a bitmap (e.g., received in status report configuration 310). For example, RIS CU 305 may verify the first control message by confirming that the first signature is associated with RIS configuration 325-a. RIS CU 305 may configure RIS 307 according to RIS configuration 325-a. RIS 307 may remain in RIS configuration 325-a until RIS CU 305 receives a second control message indicating RIS configuration 325-b and a second signature, at which time RIS CU 305 may configure RIS 307 according to RIS configuration 325-b. RIS CU 305 may verify the second control message based on the second signature being associated with RIS configuration 325-b, for example, according to the bitmap.

[0150] Device 309 may send a third control message indicating illegal configuration 330 to RIS CU 305 in an attempt to control RIS 307. However, the third control message may lack a signature, or may include an incorrect signature (e.g., a signature not included in the bitmap or associated with an incorrect RIS configuration). For example, RIS CU 305 may determine that the third control message is from an unauthorized source based on a mismatch between the bitmap, the included signature, and illegal configuration 330. In some cases, RIS CU 305 may be triggered to send a status report (e.g., status report 315-b) based on receiving illegal configuration 330 (e.g., based on determining that illegal configuration 330 was sent by an unauthorized source).

[0151] Based on the status report configuration 310, the RIS CU 305 may send (e.g., to the device 303) a status report 315-b indicating a list of RIS configurations received at the RIS CU 305 between a first reporting event (e.g., transmission of the status report 315-a) and a second reporting event (e.g., transmission of the status report 315-b). For example, the RIS CU 305 may include in the status report 315-b an indication of the RIS configuration 325-a, the RIS configuration 325-b, and the illegal configuration 330. The RIS CU 305 may send the status report 315-b according to the transmission mode indicated by the mode configuration 320. For example, the RIS CU 305 may send the status report 315-b on a set of frequency resources according to a resource element pattern. In addition, the RIS CU 305 may send the status report 315-b in a first time domain resource of a set of time domain resources corresponding to the RNTI pattern, wherein the status report 315-b includes an indication of a first RNTI corresponding to the first time domain resource.

[0152] The device 303 may receive the status report 315-b and may verify that the status report 315-b originates from the RIS CU 305 based on the set of frequency resources, first RNTIs, and first time domain resources being consistent with (e.g., matching) the resource element pattern and the RNTI pattern indicated in the pattern configuration 320. The device 303 may compare the indicated list of RIS configurations received at the RIS CU 305 with the list of RIS configurations 325 sent by the device 303. Due to the illegal configuration 330, the device 303 may identify a mismatch between the indicated list and the list of RIS configurations sent, which may enable the device 303 to identify that the illegal configuration 330 is unauthorized.

[0153] Additionally or alternatively, the device 303 may compare the current operation of the RIS 307 to one or more RIS configurations 325 sent by the device 303 to determine whether the current operation of the RIS 307 is legal. For example, the list of indicated RIS configurations may indicate that the RIS 307 is currently operating according to an illegal configuration 330. The device 303 may determine that the illegal configuration 330 does not correspond to any of the RIS configurations 325-a or 325-b. Based on the illegal configuration 330, the device 303 may determine that the operation of the RIS 307 is also illegal. The device 303 may send a RIS configuration 325-c to regain control of the RIS CU 305 and return the RIS 307 to the intended configuration. The RIS CU 305 may configure the RIS 307 according to the RIS configuration 325-c.

[0154] RIS CU 305 may send a status report 315-c according to status report configuration 310 and mode configuration 320. Status report 315-c may indicate a list of RIS configurations received at RIS CU 305 between a second reporting event (e.g., transmission of status report 315-b) and a third reporting event (e.g., transmission of status report 315-c). Thus, status report 315-c may indicate RIS configuration 325-c. Additionally, in some examples, RIS CU 305 may include in status report 315-c a third signature corresponding to RIS configuration 325-c according to the bitmap. For example, the third signature may correspond to a current state of RIS CU 305 (e.g., operating state, RIS configuration).

[0155] The RIS CU 305 may send the status report 315-c on a second frequency resource set according to the resource element pattern and on a second time domain resource of the time domain resource set corresponding to the RNTI pattern. The RIS CU 305 may include in the status report 315-c an indication of a second RNTI corresponding to the second time domain resource.

[0156] Figure 4 4 shows an example of a process flow 400 in a system that supports configuration of RIS reporting events according to one or more aspects of the present disclosure. The process flow 400 may be implemented or performed by referring to Figures 1 to 3 For example, a process flow may include one or more devices 405 (eg, device 405-a, device 405-b), which may be referenced Figures 1 to 3 In addition, the process flow 400 may be implemented by the RIS 410, which includes reference Figures 1 to 3 In the following description of process flow 400, operations between device 405 and RIS 410 may occur in a different order or at a different time than shown. Some operations may also be omitted from process flow 400, while other operations may also be added to process flow 400.

[0157] At 420, device 405-a may send, and RIS 410 may receive, a first message indicating a status report configuration including a set of parameters for sending one or more status reports associated with operation of RIS 410. The first message may be an example of a PDSCH, a PSSCH, etc. In some cases, the first message may be an example of a control message, such as a PDCCH, a PSCCH, an RRC message, a MAC-CE, a DCI, etc. In some cases, the set of parameters may include a number of status reports to be sent by RIS 410, a status report periodicity for sending the one or more status reports, one or more operating parameters associated with current operation of RIS 410 to be included in the one or more status reports, a triggering event for sending the one or more status reports, a bitmap for indicating a mapping between a set of communication configurations and a set of symmetric keys, or a combination thereof.

[0158] The one or more operational parameters associated with the current operation of RIS 410 may include a current operational state of RIS 410, a current configuration of a set of reflective elements of RIS 410, a number of communication configurations received by RIS 410, a list of communication configurations received by RIS 410, or a combination thereof. The indication of a triggering event for sending one or more status reports may include an indication of a change in one or more measurement values ​​associated with receiving one or more messages at RIS 410. The first message may further indicate the one or more measurement values, which may include AoA, RSRP, RSRQ, SINR, or a combination thereof.

[0159] At 425, device 405-a may send, and device 405-b may receive, a second message indicating a configuration of a set of status reports to be sent by RIS 410 (e.g., to device 405-b). The second message may be an example of a PDSCH, PSSCH, etc. In some cases, the second message may be an example of a control message, such as a PDCCH, PSCCH, RRC message, MAC-CE, DCI, etc. In some examples, the second message may indicate a triggering event associated with transmission of the status report by RIS 410. For example, the second message may indicate one or more measurements to be performed by device 405-b, where the triggering event consists of a change in one or more measurement values ​​associated with the one or more measurements.

[0160] At 430, device 405-a may send and RIS 410 may receive a third message indicating a transmission mode configuration (e.g., resource element pattern, RNTI pattern) for one or more status reports. For example, the third message may indicate a resource element pattern including a random resource pattern, a frequency hopping pattern, or a combination thereof. Additionally or alternatively, the third message may indicate an RNTI pattern for one or more status reports and an RNTI set associated with the RNTI pattern. The indication of the RNTI pattern may include an indication of a time domain resource set corresponding to the indicated RNTI set.

[0161] In some cases, the third message may be an example of PDSCH, PSSCH, etc. In other cases, the third message may be an example of a control message, such as PDCCH, PSCCH, RRC message, MAC-CE, DCI, etc.

[0162] At 435, device 405-a may send and RIS 410 may receive a first control message (e.g., an RRC message, a MAC-CE, a DCI) indicating a first communication configuration of RIS 410. In some examples, device 405-a may include in the first control message a first signature generated by device 405-a based on a symmetric key (e.g., a private key). The first signature may be associated with device 405-a and may include a bit sequence. In some examples, device 405-a may generate the first signature based on the first communication configuration (e.g., based on one or more beam weights or phase configurations of the first communication configuration and associated with one or more reflective elements of RIS 410). The first signature may be mapped to the first communication configuration (e.g., as indicated in the status report configuration sent to RIS 410 at 420) based on a bitmap. Based on receiving the first control message, RIS 410 may verify that the first signature maps to the first communication configuration based on the bitmap.

[0163] At 440 , RIS 410 may configure the set of reflective elements according to a first communication configuration of RIS 410 , eg, based on receiving the first control message.

[0164] At 445, device 405-a may send and RIS 410 may receive a second control message (e.g., RRC message, MAC-CE, DCI) indicating a second communication configuration of RIS 410. In some examples, device 405-a may include a second signature generated by device 405-a based on a symmetric key. In some examples, device 405-a may generate the second signature based on the second communication configuration (e.g., based on one or more beam weights or phase configurations of the second communication configuration and associated with one or more reflective elements of RIS 410). The second signature may be mapped to the second communication configuration based on the bitmap. Based on receiving the second control message, RIS 410 may verify that the second signature maps to the second communication configuration based on the bitmap.

[0165] At 450 , RIS 410 may reconfigure the set of reflective elements according to a second communication configuration of RIS 410 , eg, based on receiving the second control message.

[0166] At 455, the RIS 410 may perform one or more measurements to determine a change in one or more measurement values ​​associated with the triggering event (e.g., indicated in the status reporting configuration received at 420). For example, the RIS 410 may perform a first set of one or more measurements associated with the reception of the first control message at 435 (e.g., AoA, RSRP, RSRQ, SINR measurements) and a second set of one or more measurements associated with the reception of the second control message at 455 (e.g., AoA, RSRP, RSRQ, SINR measurements). The RIS 410 may compare the first set of one or more measurements (e.g., a first set of measurement values ​​associated with the first set of one or more measurements) and the second set of one or more measurements (e.g., a second set of measurement values ​​associated with the second set of one or more measurements) to determine a change in the measurement values.

[0167] If, at 455, RIS 410 determines that one or more measurements have changed, RIS 410 may be triggered to send a first status report to device 405-a at 460. The first status report may indicate whether current operation of RIS 410 corresponds to a valid communication configuration (e.g., a communication configuration sent by device 405-a, such as the first communication configuration or the second communication configuration). For example, the first status report may indicate that RIS 410 is currently operating according to the second communication configuration.

[0168] A first status report may be sent by RIS 410 and received by device 405-a according to the status reporting configuration indicated at 420 and the pattern configuration indicated at 430. For example, RIS 410 may include an indication of one or more operating parameters and an indication of a first RNTI in the first status report. RIS 410 may send the first status report in frequency domain resources based on the resource element pattern and in time domain resources based on the RNTI pattern (e.g., corresponding to the first RNTI).

[0169] In some examples, RIS 410 may include an indication of the signature in the first status report. For example, RIS 410 may include an indication of the signature associated with the current operation (e.g., state or configuration) of RIS 410. In some cases, the current operation (e.g., state or configuration) of RIS 410 may correspond to a most recently received communication configuration (e.g., based on a bitmap), such as the communication configuration received at 445. Additionally or alternatively, if the second control message for indicating the communication configuration at 445 includes a signature (e.g., a second signature), RIS 410 may include the second signature in the first status report.

[0170] Based on receiving the first status report, device 405-a may compare the current operation of RIS 410 (e.g., as indicated by the first status report) with the respective communication configuration sent by device 405-a to determine whether the current operation of RIS 410 is legal. For example, device 405-a may determine that the current operation of RIS 410 corresponds to the second communication configuration and is legal.

[0171] At 465, device 405-a may send, and RIS 410 may receive, a third control message (e.g., RRC message, MAC-CE, DCI) indicating a third communication configuration of RIS 410. In some examples, device 405-a may include a third signature generated by device 405-a based on a symmetric key. In some examples, device 405-a may generate a third signature based on a third communication configuration (e.g., based on one or more beam weights or phase configurations of the third communication configuration and associated with one or more reflective elements of RIS 410). The third signature may be mapped to the third communication configuration based on the bitmap. Based on receiving the third control message, RIS 410 may verify that the third signature maps to the third communication configuration based on the bitmap.

[0172] At 470 , RIS 410 may reconfigure the set of reflective elements according to a third communication configuration of RIS 410 , eg, based on receiving the third control message.

[0173] At 475, device 405-b may perform one or more measurements associated with receiving the third control message at RIS 410. For example, device 405-b may perform one or more measurements to obtain one or more measurement values, such as AoA, RSRP, RSRQ, SINR, or a combination thereof. Device 405-b may determine that one or more measurement values ​​have changed, for example, relative to one or more corresponding previous measurement values. A change in the measurement value determined by device 405-b may be considered a triggering event.

[0174] At 480, based on determining the change in the measurement value, device 405-b may send, and RIS 410 may receive, a fourth message (e.g., a control message, such as an RRC message, MAC-CE, DCI, etc.) to indicate that RIS 410 will send a status report to device 405-b. The fourth message may be an example of a trigger message. That is, receiving the fourth message at RIS 410 may be considered a trigger event at RIS 410.

[0175] At 485, in response to the trigger message, the RIS 410 may send, and the device 405-b may receive, a second status report associated with a current operation (e.g., state or configuration) of the RIS 410. The second status report may indicate whether the current operation of the RIS 410 corresponds to one of the communication configurations sent by the device 405-a (e.g., the first communication configuration, the second communication configuration, or the third communication configuration).
