[0003] The following relates to wireless communications, including interference management for reconfigurable smart surfaces (RIS). Background Art

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, 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 (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations or one or more network access nodes, each base station or network access node simultaneously supporting communication for multiple communication devices, which may be further referred to as user equipment (UE).

[0005] Some wireless communication systems may employ reconfigurable smart surfaces (RIS) to increase cell coverage and channel diversity. A RIS may be an example of a passive device that may reflect, refract, or otherwise passively direct a signal in a desired direction. However, in some cases, a signal reflected (e.g., refracted, directed) by a RIS may cause interference at other wireless devices. Summary of the invention

The base station may determine a second activation schedule of one or more RIS or resource allocation for communicating with the UE based on the interference measurement information. The base station may communicate with the UE based on the second activation schedule or resource allocation.

[0070] In some wireless communication systems, a reconfigurable smart surface (RIS) can be used to increase cell coverage and channel diversity. The RIS can be an example of a passive (e.g., low-power) device that can reflect, refract, or otherwise passively manipulate a signal in a desired direction. In some cases, the RIS may not actively decode, encode, amplify, or otherwise process a signal reflected by the RIS. For example, the RIS may have a configurable (e.g., controllable) reflectivity or refractive index (e.g., angle) (e.g., based on a configurable characteristic, such as an electromagnetic characteristic or an electromechanical characteristic). A controller of the RIS can configure (e.g., adjust) the RIS to control the direction of reflection or refraction. As a more specific example, a RIS controller can adjust various gratings on the RIS (e.g., the spacing, orientation, or another characteristic of the grating) to guide an incident wave in a desired direction.

[0071] Some wireless communication systems may include multiple RISs that may be connected to or controlled by multiple base stations or a central RIS controller. For example, a first base station may use a first RIS to communicate with a first user equipment (UE), and a second base station may use a second RIS to communicate with a second UE. However, in some cases, signals reflected by the first RIS (e.g., signals reflected from the first UE to the first base station or vice versa) may assist communication between the first base station and the first UE, but also interfere with or otherwise disrupt communication between the second base station and the second UE. Similarly, signals reflected by the second RIS may assist communication between the second base station and the second UE, but also cause interference at the first UE or the first base station.

[0072] The techniques described herein provide for managing interference caused by RIS by performing interference measurements on RIS-centric interference measurement resources (RC-IMRs). In some examples, the UE may receive a downlink reference signal from a base station on the RC-IMR and may generate a RIS-centric interference measurement set based on the downlink reference signal. Thus, the UE may send an indication of the RIS-centric interference measurement to the base station, and the base station may use the RIS-centric interference measurement provided by the UE to make scheduling decisions or determine optimal RIS configuration settings (e.g., directional settings, active and inactive periods).

[0073] In other examples, the UE may send an uplink reference signal to the base station on the RC-IMR, and the base station may generate an interference measurement set centered on the RIS based on the uplink reference signal. The base station may use the interference measurement set centered on the RIS to improve subsequent communications with the UE (e.g., by determining appropriate resource allocations for the UE). In some examples, the base station may coordinate with other base stations or a central RIS controller to determine a RIS activation schedule that minimizes RIS-centered interference (e.g., interference caused by the RIS). The techniques described herein may result in reduced interference and improved communication reliability, among other benefits.

[0074] Aspects of the present disclosure are first described in the context of wireless communication systems and process flows. Aspects of the present disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flow diagrams related to interference management for RIS.

[0075] Figure 1An example of a wireless communication system 100 supporting interference management for RIS according to aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating according to other systems and radio technologies (including future systems and radio technologies not explicitly mentioned herein).

[0076] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, etc. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more radio access technologies (RATs).

[0077] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or both stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1 . The UEs 115 described herein may be capable of supporting communications with various types of devices, such as Figure 1 Other UEs 115 or network entities 105 are shown.

[0078] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, apparatus, device, computing system, etc. may include disclosure of UE 115, network entity 105, apparatus, device, computing system, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.

[0079] As described herein, a node (which may be referred to as a node, a network node, a network entity, or a wireless node) may include, may be, or may be included in (e.g., as a component of) a base station 140 (e.g., any base station described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, a computing system, an integrated access and backhaul (IAB) node, a distributed unit (DU), a central unit (CU), a remote / radio unit (RU) (which may also be referred to as a remote radio unit (RRU)), and / or another processing entity configured to perform any of the techniques described herein. For example, the network node may be a UE 115. As another example, the network node may be a base station 140 or a network entity 105. As another example, a first network node may be configured to communicate with a second network node or a third network node.

[0080] In one aspect of this example, the first network node may be UE 115, the second network node may be base station 140, and the third network node may be UE 115. In another aspect of this example, the first network node may be UE 115, the second network node may be base station 140, and the third network node may be base station 140. In yet other aspects of this example, the first network node, the second network node, and the third network node may be different relative to these examples. Similarly, references to UE 115, base station 140, devices, equipment, computing systems, etc. may include disclosure of UE 115, base station 140, devices, equipment, computing systems, etc. as network nodes. For example, a disclosure that UE 115 is configured to receive information from base station 140 also discloses that the first network node is configured to receive information from the second network node.

[0081] Consistent with the present disclosure, once a specific example is expanded according to the present disclosure (e.g., a UE is configured to receive information from a base station and it is also disclosed that a first network node is configured to receive information from a second network node), a broader example of a narrower example can be interpreted inversely, but in a broad, open-ended manner. In the above example where a UE 115 is configured to receive information from a base station and it is also disclosed that a first network node is configured to receive information from a second network node, the first network node may refer to a first UE 115 configured to receive information, a first base station 140, a first device, a first equipment, a first computing system, a first set of one or more components, a first processing entity, etc.; and the second network node may refer to a second UE 115, a second base station 140, a second device, a second equipment, a second computing system, a second set of one or more components, a second processing entity, etc.

[0082] As described herein, different terms may be used in various aspects to describe the communication of information (e.g., any information, signal, etc.). Disclosure of one communication term includes disclosure of other communication terms. For example, a first network node may be described as being configured to send information to a second network node. In this example and consistent with the present disclosure, disclosure that the first network node is configured to send information to the second network node includes disclosure that the first network node is configured to provide, transmit, output, communicate, or send information to the second network node. Similarly, in this example and consistent with the present disclosure, disclosure that the first network node is configured to send information to the second network node includes disclosure that the second network node is configured to receive, obtain, or decode information provided, transmitted, output, communicated, or sent by the first network node.

[0083] In some examples, the network entities 105 may communicate with the core network 130 or with each other. 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 each network entity 105) or indirectly (e.g., via the core network 130) via the backhaul communication link 120 (e.g., according to X2, Xn or other interface protocols). In some examples, the network entities 105 may communicate with each other via the midhaul communication link 162 (e.g., according to the midhaul interface protocol) or the fronthaul communication link 168 (e.g., according to the fronthaul interface protocol). The backhaul communication link 120, the midhaul communication link 162, or the fronthaul communication link 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .

[0084] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a home Node B, a home evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).

[0085] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an IAB network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a DU 165, a RU 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RTRIC), a non-real-time RIC (non-RT RIC)), or a service management and orchestration (SMO) 180 system. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), an RRU, or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0086] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, and RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DUs 165 and RUs 170, such that the DUs 165 may support one or more layers of the protocol stack, and the RUs 170 may support one or more different layers of the protocol stack. The DUs 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 may be within the protocol layer (e.g., some functions of the protocol layer may be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 may be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 may be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 may be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented according to an interface (eg, channel) between layers of a protocol stack supported by a corresponding network entity 105 communicating via such communication link.

[0087] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., 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 a coupled IAB donor's DU 165. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.

[0088] 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 IAB donor 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, the IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The 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., CUs 160 associated with alternative IAB donors) via an Xn-C interface (which may be an example of a portion of a backhaul link).

[0089] An IAB node 104 may refer to a RAN node that provides IAB functionality (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). DU 165 may act as a distributed scheduling node toward child nodes associated with IAB node 104, and IAB-MT may act as a scheduled node toward a parent node associated with IAB node 104. That is, an IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., an IAB donor may relay transmissions to a UE through one or more other IAB nodes 104). Additionally or alternatively, depending on the relay chain or configuration of the AN, an IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104. Thus, the IAB-MT entity of IAB node 104 may provide a Uu interface for child IAB node 104 to receive signaling from parent IAB node 104 , and a DU interface (eg, DU 165 ) may provide a Uu interface for parent IAB node 104 to signal to child IAB node 104 or UE 115 .

[0090] For example, the IAB node 104 may be referred to as a parent node supporting child IAB node communications or a child node associated with an IAB donor. The IAB donor may include a CU 160 having a wired or wireless connection to the core network 130 (e.g., a backhaul communication link 120), and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay the transmission to the UE 115 through the IAB node 104, or may directly signal the UE 115 to transmit. The CU 160 of the IAB donor may signal the IAB node 104 that the communication link is established via the F1 interface, and the IAB node 104 may schedule the transmission (e.g., the transmission relayed from the IAB donor to the UE 115) through the DU 165. That is, data may be relayed to and from the IAB node 104 via the NR Uu interface of the MT to the IAB node 104 via signaling. 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 .

[0091] In the context of the techniques described herein being applied to a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support the techniques described herein for performing non-terrestrial cell measurements in connected mode. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally or alternatively be performed by one or more components of the disaggregated RAN architecture (e.g., an IAB node 104, a DU 165, a CU 160, a RU 170, a RIC 175, a SMO 180).

[0092] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0093] The UE 115 described herein may be capable of communicating with various types of devices, such as other UEs 115, which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.

[0094] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a set of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any part (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send", "receive", or "communicate" when referring to the network entity 105 may refer to any part of the network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of the RAN communicating with another device (e.g., directly or via one or more other network entities 105).

[0095] 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 set of bandwidths of carriers of a particular radio access technology (e.g., 1.4 megahertz (MHz), 3 MHz, 5 MHz, 10 MHz, 15 MHz, 20 MHz, 40 MHz, or 80 MHz). A device (e.g., a network entity 105 or a UE 115) of the wireless communication system 100 may have a hardware configuration that supports communications using a particular carrier bandwidth, or may be configurable to support communications using one of the carrier bandwidths in the set of carrier bandwidths. In some examples, the wireless communication system 100 may include a network entity 105 or a UE 115 that supports concurrent communications using carriers associated with multiple carrier bandwidths. In some examples, each served UE 115 may be configured to operate using a portion (e.g., a subband, a BWP) or all of the carrier bandwidth.

[0096] The signal waveform transmitted via the carrier 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 technology, 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 may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme or the coding rate of the modulation scheme), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high rate of communication. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.

[0097] One or more parameter sets for a carrier may be supported, and the parameter sets may include subcarrier spacing (Δf) and cyclic prefixes. A carrier may be divided into one or more BWPs with the same or different parameter sets. 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 of a UE 115 may be constrained to one or more active BWPs.

[0098] The time interval for the network entity 105 or the UE 115 may be expressed as a multiple of a basic time unit, which may be, for example, a sampling period of T s =1 / (Δf max ·N f ) seconds, for which Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. Time intervals of the communication resources may be organized according to radio frames, each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).

[0099] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.

[0100] 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 a burst of a shortened TTI (sTTI)).

[0101] Physical channels may be multiplexed using carriers for communication according to various techniques. Physical control channels and physical data channels may be multiplexed for signaling via downlink carriers using, for example, one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region for control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .

[0102] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different radio access technologies.

[0103] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video, or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.

[0104] In some examples, the UE 115 may be configured to support direct communication 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), and the one or more UEs may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each other UE 115 in the group. In some examples, the network entity 105 may facilitate scheduling of resources for D2D communication. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105 .

[0105] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access layer (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0106] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Typically, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) 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.

[0107] The wireless communication system 100 can utilize 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 RF spectrum bands, devices such as network entity 105 and UE 115 can use carrier sensing for conflict detection and avoidance. In some examples, operations performed using unlicensed bands can be combined with component carriers operating using licensed bands (e.g., LAA) based on carrier aggregation configuration. Operations performed using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, and the like.

[0108] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a set of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.

[0109] The network entity 105 or UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technique may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO techniques include 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.

[0110] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular direction (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other direction).

[0111] 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) beam directions for later transmission or reception by the network entity 105.

[0112] 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 the transmission along the single beam direction may be determined based on signals sent along one or more beam directions. For example, UE 115 may receive one or more of the signals sent by network entity 105 along different directions, and may report to network entity 105 an indication of the signal received by UE 115 with the highest signal quality or other acceptable signal quality.

[0113] In some examples, transmission by a device (e.g., by network entity 105 or UE 115) may be performed using multiple beam directions, and the device may use a combination of digital precoding or beamforming to generate a combined beam for transmission (e.g., from network entity 105 to UE 115). UE 115 may report feedback indicating precoding weights for one or more beam directions, and the feedback may correspond to a configured beam set across a system bandwidth or one or more subbands. Network entity 105 may send a reference signal (e.g., a cell-specific reference signal (CRS), a channel state information reference signal (CSI-RS)), which may or may not be precoded. UE 115 may provide feedback for beam selection, which may be a precoding matrix indicator (PMI) or codebook-based feedback (e.g., a multi-faceted codebook, a linear combination codebook, a port selection codebook). Although these techniques are described with reference to signals sent along one or more directions by a network entity 105 (e.g., base station 140, RU 170), UE 115 may use similar techniques to send signals multiple times along different directions (e.g., to identify a beam direction for subsequent transmission or reception by UE 115), or to send signals along a single direction (e.g., to send data to a receiving device).

[0114] 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) may perform receiving operations (e.g., directional listening) according to multiple receiving configurations. For example, the receiving device may perform reception according to multiple receiving directions by: receiving via different antenna subarrays, processing the received signals according to different antenna subarrays, receiving according to different receiving beamforming weight sets (e.g., different directional listening weight sets) applied to signals received at multiple antenna elements of an antenna array, or processing the received signals according to different receiving beamforming weight sets applied to signals received at multiple antenna elements of an antenna array, any of which may be referred to as "listening" according to different receiving configurations or receiving directions. In some examples, the receiving device may use a single receiving configuration to receive along a single beam direction (e.g., when receiving a data signal). A single receive configuration may be aligned along a beam direction determined based on listening according to different receive configuration directions (e.g., a beam direction determined to have the highest signal strength, highest signal-to-noise ratio (SNR), or other acceptable signal quality based on listening according to multiple beam directions).

[0115] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority processing and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection or correction techniques to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection that supports a radio bearer for user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map a transport channel to a physical channel.

[0116] UE 115 and network entity 105 may support retransmission of data to increase the possibility of successfully receiving data. Hybrid automatic repeat request (HARQ) feedback is a technology for increasing the possibility of correctly receiving data via a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve the throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, the device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific time slot for data received via a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.

[0117] Some wireless communication systems can use RIS to provide coverage enhancement. RIS can be an example of a low-power passive device without a transceiver that operates like a phased array. RIS can be used to guide incident waves in a desired direction using a controller. RIS can change the conditions of the communication channel between the transmitter and the receiver. For example, RIS can provide an alternative path from the transmitter to the receiver, which can change the channel characteristics of the communication channel. Therefore, RIS can be used to artificially induce a desired channel response. Specifically, the desired channel response can be obtained by turning on or off RIS, adjusting the number of RIS present in the environment, and adapting the simulated beamforming weights (e.g., directional settings) of RIS. Although RIS can help improve communication between two devices (e.g., endpoints), using RIS can sometimes cause higher interference levels. The technology described herein can support a technology for reducing interference centered on RIS (e.g., interference caused by RIS), which can lead to higher communication reliability and increased system throughput.

[0118] Figure 2An example of a wireless communication system 200 supporting interference management for RIS according to aspects of the present disclosure is illustrated. The wireless communication system 200 may implement aspects of the wireless communication system 100 or be implemented by these aspects. For example, the wireless communication system 200 may include a network entity 105-a and a UE 115-a, which may be a reference Figure 1 Examples of the corresponding devices described. In the wireless communication system 200, the UE 115-a can communicate with the network entity 105-a via the RIS210.

[0119] In some examples, RIS 210 may be controlled by network entity 105-a. For example, network entity 105-a may control RIS 210 via interface 250. In other examples, RIS 210 may be controlled by a central RIS controller (e.g., see Figure 4 RIS 210 may be used to relay (e.g., deflect, refract, reflect) signals between network entity 105-a and UE 115-a. For example, a wave (e.g., an incident wave) may be transmitted at an angle of incidence (e.g., θ i ) arrives at RIS 210 and can be reflected at an angle (e.g., θ r ) leaves RIS210 (e.g., as a reflected wave).

[0120] RIS 210 may be configured with a controller 205 that may adjust or otherwise configure a directional setting of RIS 210. For example, controller 205 may adjust gratings 220 on RIS 210 to control the angle at which waves are reflected from RIS 210. By adjusting gratings 220 of RIS 210, controller 205 may be able to direct waves (e.g., signals) in a particular direction. In some examples, controller 205 may provide a small amount of power to a surface of RIS 210 to improve the reflective properties of RIS 210 (e.g., to increase the power or quality of a signal reflected by RIS 210). The amount of power consumed by RIS 210 may be negligible compared to a power amplifier or other active repeater device.

[0121] According to aspects of the present disclosure, the network entity 105-a may send control signaling 235 to the UE 115-a. In some examples, the network entity 105-a may send the control signaling 235-a to the UE 115-a via the RIS 210. That is, the RIS 210 may relay the control signaling 235-a from the network entity 105-a to the UE 115-a. In other examples, the network entity 105-a may send the control signaling 235-b to the UE 115-a via a direct communication link. The control signaling 235 may indicate a set of RC-IMRs (e.g., time and frequency resources) to be used for RIS interference measurements (e.g., interference measurements associated with the RIS 210). Each RC-IMR may correspond to a different configuration of the RIS 210. For example, RIS210 can be configured with a first set of directional settings (e.g., beamforming weights) and a first activation state (e.g., on or off) during a first RC-IMR, and can be configured with a second set of directional settings and a second activation state (e.g., on or off) during a second RC-IMR.

[0122] In some examples, the network entity 105-a may send a downlink reference signal 230 to the UE 115-a on the RC-IMR set. For example, the network entity 105-a may send the downlink reference signal 230-a to the UE 115-a via the RIS 210. Additionally or alternatively, the network entity 105-a may send a downlink reference signal 230-b to the UE 115-a via a direct communication link. In other examples, the UE 115-a may send an uplink reference signal 245 to the network entity 105-a on the RC-IMR set. For example, the UE 115-a may send the uplink reference signal 245-a to the network entity 105-a via the RIS 210. Additionally or alternatively, the UE 115-a may send the uplink reference signal 245-b to the network entity 105-a via a direct communication link.

[0123] For example, if the network entity 105-a sends a downlink reference signal 230 to the UE 115-a on the RC-IMR, the UE 115-a may perform an interference measurement set based on the downlink reference signal 230. For example, the UE 115-a may measure the reference signal received power (RSRP) of the downlink reference signal 230. Therefore, the UE 115-a may send a measurement report 240 to the network entity 105-a. The measurement report 240 may indicate the interference measurement performed by the UE 115-a. In some examples, the UE 115-a may send the measurement report 240-a to the network entity 105-a via the RIS 210. In other examples, the UE 115-a may send the measurement report 240-b to the network entity 105-a via a direct communication link. Alternatively, if the UE 115-a sends the uplink reference signal 245 to the network entity 105-a on RC-IMR, the network entity 105-a may perform a set of interference measurements on the uplink reference signal 245. For example, the network entity 105-a may measure the RSRP of the uplink reference signal 245.

[0124] The network entity 105-a may determine an optimal configuration of the RIS 210 (e.g., beamforming weights, active periods, inactive periods) or an appropriate allocation of resources (e.g., time and frequency resources) for communicating with the UE 115-a based on the measurement report 240 from the UE 115-a or the interference measurement performed by the network entity 105-a. In some examples, the network entity 105-a may determine an optimal configuration of the RIS 210 or an appropriate allocation of resources for the UE 115-a based on coordination (e.g., negotiation) with other network entities 105 or a central RIS controller via an Xn interface. In such examples, the network entity 105 (e.g., the network entity 105-a and other network entities 105) and the central RIS controller may jointly determine RIS configuration settings or resource allocations that minimize RIS-centric interference levels in the wireless communication system 200.

[0125] The wireless communication system 200 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable the network entity 105-a to determine an optimal RIS configuration for the RIS 210 or a suitable allocation of resources for communicating with the UE 115-a based on performing or receiving interference measurements associated with the RIS 210. The optimal RIS configuration and the suitable allocation of resources may reduce interference caused by the RIS 210 and increase the likelihood that the network entity 105-a can successfully communicate with the UE 115-a via the RIS 210.

[0126] Figure 3A and Figure 3BAn example of a wireless communication system 300 and a wireless communication system 301 supporting interference management for RIS according to aspects of the present disclosure is illustrated. The wireless communication system 300 and the wireless communication system 301 may implement aspects of the wireless communication system 100 or the wireless communication system 200, or be implemented thereby. For example, the wireless communication system 300 may include a network entity 105-b, a network entity 105-c, a UE 115-b, and a UE 115-c, which may be reference Figure 1 and Figure 2 Similarly, the wireless communication system 301 may include a network entity 105-d, a network entity 105-e, a UE 115-d and a UE 115-e, which may be reference Figure 1 and Figure 2 The wireless communication system 300 may also include RIS 310-a and RIS 310-b, which may be reference Figure 2 Similarly, the wireless communication system 301 may include RIS 310-c and RIS 310-d, which may also be referenced Figure 2 An example of the RIS 210 is shown. In the wireless communication system 300 and the wireless communication system 301, the RIS 310 may be configured with an activation schedule that results in lower RIS-centric interference.

[0127] In wireless communication system 300, network entity 105-b may control RIS 310-a and UE 115-b. Similarly, network entity 105-c may control RIS 310-b and UE 115-c. Figure 3A As illustrated by the example of , the direct line of sight from network entity 105-b to UE 115-b may be obstructed by an obstacle (e.g., resulting in a blocked signal from network entity 105-b). Therefore, the presence of RIS 310-a can enable communication between network entity 105-b and UE 115-b. That is, a signal from network entity 105-b (e.g., a desired signal) can reach UE 115-b via RIS 310-a. However, the presence of RIS 310-a may also cause interference at UE 115-c (e.g., transmissions from network entity 105-b may interfere with UE 115-c). Therefore, turning on RIS 310-a can improve communication between network entity 105-b and UE 115-b while adversely affecting communication between network entity 105-c and UE 115-c. In contrast, shutting down the RIS 310-a may improve communications between the network entity 105-c and the UE 115-c while adversely affecting communications between the UE 115-b and the network entity 105-b.

[0128] In the wireless communication system 301, the network entity 105-d may control the RIS 310-c and the UE 115-d. Similarly, the network entity 105-e may control the RIS 310-d and the UE 115-e. Figure 3B As illustrated by the example of , the direct line of sight from the network entity 105-e to the UE 115-e may be obstructed by an obstacle (e.g., resulting in a blocking signal from the UE 115-e). Therefore, the presence of the RIS 310-d may enable communication between the UE 115-e and the network entity 105-e. That is, a signal (e.g., a desired signal) from the UE 115-e may reach the network entity 105-e via the RIS 310-d. For example, the RIS 310-d may reflect (e.g., deflect, refract) uplink transmissions from the UE 115-e to the network entity 105-e. However, these uplink transmissions may cause interference at the network entity 105-d. Therefore, although the presence of the RIS 310-d may improve the communication between the UE 115-e and the network entity 105-e, the presence of the RIS 310-d may also have an adverse effect on the communication between the network entity 105-d and the UE 115-d.

[0129] According to aspects of the present disclosure, the network entity 105 can mitigate interference caused by the RIS 310 by performing interference measurements on the RC-IMR. For example, the UE 115-c can receive a downlink reference signal from the network entity 105-c on the RC-IMR, and can generate a RIS-centric interference measurement set based on the downlink reference signal. Therefore, the UE 115-c can send an indication of the RIS-centric interference measurement to the network entity 105-c. The network entity 105-c can use the RIS-centric interference measurement provided by the UE 115-c to determine appropriate resource allocations (e.g., for the UE 115-c) or RIS configuration settings (e.g., directional settings, active periods, and inactive periods) for the RIS 310.

[0130] In other examples, the UE 115-e may send an uplink reference signal to the network entity 105-e on the RC-IMR, and the network entity 105-e may generate an RIS-centric interference measurement set based on the uplink reference signal from the UE 115-e. The network entity 105-e may use the RIS-centric interference measurement set to improve subsequent communications with the UE 115-e (e.g., by determining an appropriate resource allocation for the UE 115-e). In some examples, the network entity 105-e may coordinate with the network entity 105-d to determine a RIS activation schedule that minimizes RIS-centric interference (e.g., interference caused by the RIS 310). For example, the network entity 105-e may determine an appropriate activation schedule for the RIS 310-d based on interference measurements provided by the network entity 105-d.

[0131] Wireless communication system 300 and wireless communication system 301 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable network entity 105 to jointly determine an optimal RIS configuration for RIS 310 or a suitable allocation of resources for communicating with UE 115 based on exchanging (e.g., communicating) interference measurements associated with RIS 310. The optimal RIS configuration and the suitable allocation of resources may reduce interference caused by RIS 310 and increase the likelihood that network entity 105 can successfully communicate with UE 115 via RIS 310.

[0132] Figure 4 An example of a wireless communication system 400 supporting interference management for RIS according to aspects of the present disclosure is illustrated. The wireless communication system 400 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, or the wireless communication system 301. For example, the wireless communication system 400 may include a network entity 105-f, a network entity 105-g, a network entity 105-h, a UE 115-f, a UE 115-g, a UE 115-h, a UE 115-i, a UE 115-j, and a UE 115-k, which may be reference 1. Figure 1 3. The wireless communication system 400 may also include RIS 410-a, RIS 410-b, and RIS 410-c, which may be reference Figure 2 3 and the examples of RIS 210 or RIS 310. In wireless communication system 400, network entity 105 may coordinate with RIS controller 405 to determine an optimal activation schedule for RIS 410.

[0133] The wireless communication system 400 may support techniques for configuring RC-IMR between network entities 105 using the RIS controller 405. Figure 4 , there may be a RIS 410 that affects the network entity 105. The UE 115 (e.g., a user of the network entity 105), the network entity 105, and the RIS controller 405 may collaboratively determine the impact of interference due to the RIS on different users in one or more cells of the network entity 105. As described herein, one or more of the network entities 105 may initiate a session with the RIS controller 405 to perform joint resource allocation for interference measurement management between all network entities 105. The RIS controller 405 may provide the network entity 105 with measurement resource opportunities for RIS enablement or RIS disablement. Accordingly, the network entity 105 may send an indication of these resource opportunities to the UE 115.

[0134] In some examples, RIS controller 405 may initiate a session with one or more network entities 105 when a particular RIS is enabled or disabled. Specifically, RIS controller 405 may provide different combinations of on and off times for RIS 410. For example, at a first time (e.g., t 1 ), RIS 410-a may be shut down, RIS 410-b may be shut down, and RIS 410-c may be shut down (e.g., t 1 : (off, off, off)). At the second time (e.g., t 2 ), RIS 410-a may be turned off, RIS 410-b may be turned off, and RIS 410-c may be turned on (e.g., t 2 : (off, off, on)). At a third time (e.g., t 3 ), RIS 410-a may be closed, RIS 410-b may be opened, and RIS 410-c may be opened (e.g., t 3 Additionally or alternatively, the network entity 105 may negotiate (eg, via an Xn interface) to determine the time intervals for different measurement opportunities (eg, t i ) of appropriate time-frequency resources (e.g., RC-IMR).

[0135] The wireless communication system 400 may support UE measurement reporting during RIS-enabled or RIS-disabled downlink transmissions. The network entity 105 may configure the UE 115 (e.g., a user served by the network entity 105) with an appropriate RC-IMR. As described herein, the RC-IMR may represent one or more time-frequency resources corresponding to a RIS activation mode (e.g., a combination of active and inactive RIS), and different RC-IMRs within an RC-IMR set may correspond to different RIS activation modes. The UE 115 may measure the received power (e.g., RSRP) of a downlink reference signal from the network entity 105 on these resources. In some examples, the RC-IMR may be applicable to all users of a particular cell. In other examples, the RC-IMR may be applicable to UEs 115 that have reported a high received signal strength indicator (RSSI). In other examples, the RC-IMR may be applicable to one or more geographic regions of the network entity 105.

[0136] Each of the network entities 105 may send a unique downlink reference signal to the UE 115, and each of the UEs 115 may measure the received power (e.g., RSRP) of these downlink reference signals in each of the configured RC-IMRs. Thus, the UE 115 may report measurements performed on the RC-IMRs to the network entity 105. For example, the UE 115-g may report measurements performed on the RC-IMRs to the network entity 105-f, the UE 115-h may report measurements performed on the RC-IMRs to the network entity 105-g, and the UE 115-k may report measurements performed on the RC-IMRs to the network entity 105-h. After obtaining interference and signal quality reports from the UE 115, the network entity 105 may negotiate (e.g., determine) the directional settings of each of the RISs 410, the activation schedule in each time slot (e.g., whether to enable or disable each of the RISs 410), and the appropriate resource allocation for the UE 115.

[0137] The wireless communication system 400 may also support techniques for UE measurement reporting during uplink transmissions with RIS enabled or disabled. For uplink measurements, the network entity 105 may configure the UE 115 to transmit orthogonal uplink reference signals on the RC-IMR. Thus, the UE 115 may transmit orthogonal uplink reference signals during the assigned RC-IMR, and the network entity 105 may measure the RSRP of the orthogonal uplink reference signal transmissions from the UE 115 to determine the impact of the RIS 410. After measuring the RSRP of these uplink reference signals, the network entity 105 may determine the appropriate resource allocation for the UE 115 and the configuration settings for the RIS 410.

[0138] In some examples, the network entity 105 may determine appropriate resource allocations for the UEs 115 based on the activation schedule of the RIS 410 (e.g., to serve different sets of UEs 115 at different times). For example, if the UEs 115 in the first area have reported high interference levels from the RIS 410-a, the network entity 105-f may serve these UEs 115 (e.g., users) when the RIS 410-a is deactivated. This may enable the network entity 105-f to serve the UEs 115 in the first area without interference from the RIS 410-a. Similarly, if the UEs 115 in the third area have reported high interference levels from the RIS 410-b, the network entity 105-g may serve these UEs 115 when the RIS 410-b is inactive. Therefore, the network entity 105-g may serve the UEs 115 in the third area without interference from the RIS 410-b. In some examples, network entity 105 may agree on an optimal RIS activation schedule based on signal-to-interference-plus-noise ratio (SINR) measurements from UE 115. Accordingly, network entity 105 may send an indication of the optimal RIS activation schedule to RIS controller 405. Additionally or alternatively, network entity 105 may request RIS controller 405 to change a directional setting (e.g., θ) of RIS 410 to enhance received signal quality for communications between network entity 105 and UE 115.

[0139] The wireless communication system 400 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable the network entity 105 and the RIS controller 405 to jointly determine an optimal RIS configuration or a suitable allocation of resources for communicating with the UE 115 based on exchanging (e.g., communicating) interference measurements associated with the RIS 410. The optimal RIS configuration and the suitable allocation of resources may reduce RIS-centric interference (e.g., interference caused by the RIS 410) and increase the likelihood that the network entity 105 will successfully communicate with the UE 115 via the RIS 410.

[0140] Figure 5 An example of a process flow 500 for supporting interference management for RIS according to aspects of the present disclosure is illustrated. The process flow 500 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, the wireless communication system 301, or the wireless communication system 400. For example, the process flow 500 may include the network entity 105-i, the network entity 105-j, the UE 115-1, and the UE 115-m, which may be reference Figures 1 to 4The process flow 500 may also include a RIS controller 505, which may be a reference Figure 2 and Figure 4 In the following description of process flow 500, operations between network entity 105, UE 115, and RIS controller 505 may be performed in a different order or at a different time than shown. Additionally or alternatively, some operations may be omitted from process flow 500 and other operations may be added to process flow 500.

[0141] At 510, the network entity 105 may perform a RIS scheduling negotiation procedure with the RIS controller 505. During the RIS scheduling negotiation procedure, the network entity 105 may exchange control messages with the RIS controller 505. For example, the network entity 105-i may send a control message to the RIS controller 505 indicating a request for the RIS controller 505 to configure one or more RISs with a first set of orientation settings, a first set of inactive periods, or a first set of active periods. Similarly, the network entity 105-j may send a control message to the RIS controller 505 indicating a request for the RIS controller 505 to configure one or more RISs with a second set of orientation settings, a second set of inactive periods, or a second set of active periods.

[0142] RIS controller 505 may determine a first activation schedule (e.g., an initial set of orientation settings, inactive periods, and active periods) for one or more RISs based on performing a RIS schedule negotiation procedure with network entity 105. Accordingly, RIS controller 505 may configure one or more RISs with the first activation schedule. At 515-a, RIS controller 505 may send an indication of the first activation schedule to network entity 105-j. Similarly, at 515-b, RIS controller 505 may send an indication of the first activation schedule to network entity 105-i.

[0143] At 520-a, network entity 105-i may determine a first RC-IMR configuration (e.g., time and frequency resource locations) for UE 115-l based on the first activation schedule, and may send an indication of the first RC-IMR configuration to UE 115-l. At 520-b, network entity 105-j may determine a second RC-IMR configuration for UE 115-m based on the first activation schedule, and may send an indication of the second RC-IMR configuration to UE 115-m. Thus, network entity 105 may send a downlink reference signal to UE 115 on the RC-IMR. For example, network entity 105-i may send a downlink reference signal to UE 115-l on an RC-IMR set associated with the first RC-IMR configuration, and network entity 105-j may send a downlink reference signal to UE 115-m on an RC-IMR set associated with the second RC-IMR configuration.

[0144] UE 115 may perform interference measurements associated with one or more RISs based on receiving downlink reference signals from network entity 105. Specifically, UE 115-1 may perform a first interference measurement set associated with one or more RISs based on receiving downlink reference signals from network entity 105-i on an RC-IMR set associated with a first RC-IMR configuration. Similarly, UE 115-m may perform a second interference measurement set associated with one or more RISs based on receiving downlink reference signals from network entity 105-j on an RC-IMR set associated with a second RC-IMR configuration. At 525-a, UE 115-1 may generate a first measurement report based on the first interference measurement set, and may send the first measurement report to network entity 105-i. At 525-b, UE 115-m may generate a second measurement report based on the second interference measurement set, and may send the second measurement report to network entity 105-j.

[0145] At 530, network entity 105 may determine a second activation schedule (e.g., an optimal set of directional settings, active periods, and inactive periods) for one or more RISs based on the first measurement report and the second measurement report. In some examples, network entity 105-i may send a control message indicating a first set of interference measurements performed by UE 115-1 to network entity 105-j. Similarly, network entity 105-j may send a control message indicating a second set of interference measurements performed by UE 115-m to network entity 105-i. Network entity 105 may determine a second activation schedule based on exchanging these control messages. Additionally or alternatively, network entity 105 may determine an appropriate resource allocation for communicating with UE 115 based on the first measurement report and the second measurement report.

[0146] At 535, network entity 105 may send an indication of the second activation schedule to RIS controller 505. Accordingly, RIS controller 505 may reconfigure one or more RISs based on the second activation schedule. In some examples, RIS controller 505 may send a control message to network entity 105 indicating updated configurations (e.g., directional settings, inactive periods, active periods) of one or more RISs. Network entity 105 may schedule communications with UE 115 based on the updated configurations of the one or more RISs.

[0147] The process flow 500 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable the network entity 105 and the RIS controller 505 to jointly determine an optimal RIS configuration or a suitable allocation of resources for communicating with the UE 115 based on exchanging (e.g., communicating) interference measurements associated with one or more RISs. The optimal RIS configuration and the suitable allocation of resources may reduce RIS-centric interference (e.g., interference caused by one or more RISs) and increase the likelihood that the network entity 105 can successfully communicate with the UE 115 via the one or more RISs.

[0148] Figure 6 An example of a process flow 600 for supporting interference management for RIS according to aspects of the present disclosure is illustrated. The process flow 600 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, the wireless communication system 301, the wireless communication system 400, or the process flow 500. For example, the process flow 600 may include the network entity 105-k, the network entity 105-1, the UE 115-n, and the UE 115-o, which may be reference Figures 1 to 5 The process flow 600 may also include a RIS controller 605, which may be a reference Figures 2 to 5 RIS controller 405 or RIS controller 505 is an example of the RIS controller 405 or RIS controller 505 described above. In the following description of process flow 600, operations between network entity 105, UE 115, and RIS controller 605 may be performed in a different order or at a different time than shown. Additionally or alternatively, some operations may be omitted from process flow 600 and other operations may be added to process flow 600.

[0149] At 610, the network entity 105 may perform a RIS scheduling negotiation procedure with the RIS controller 605. During the RIS scheduling negotiation procedure, the network entity 105 may exchange control messages with the RIS controller 605. For example, the network entity 105-k may send a control message to the RIS controller 605 indicating a request for the RIS controller 605 to configure one or more RISs with a first set of orientation settings, a first set of inactive periods, or a first set of active periods. Similarly, the network entity 105-1 may send a control message to the RIS controller 605 indicating a request for the RIS controller 605 to configure one or more RISs with a second set of orientation settings, a second set of inactive periods, or a second set of active periods.

[0150] RIS controller 605 may determine a first activation schedule (e.g., an initial set of orientation settings, inactive periods, and active periods) for one or more RISs based on performing a RIS schedule negotiation procedure with network entity 105. Thus, RIS controller 605 may configure one or more RISs with the first activation schedule. At 615-a, RIS controller 605 may send an indication of the first activation schedule to network entity 105-1. Similarly, at 615-b, RIS controller 605 may send an indication of the first activation schedule to network entity 105-k.

[0151] At 620-a, the network entity 105-k may determine a first RC-IMR configuration (e.g., time and frequency resource locations) for the UE 115-o based on the first activation schedule, and may send an indication of the first RC-IMR configuration to the UE 115-o. At 620-b, the network entity 105-l may determine a second RC-IMR configuration for the UE 115-n based on the first activation schedule, and may send an indication of the second RC-IMR configuration to the UE 115-n. Thus, the network entity 105 may receive an uplink reference signal from the UE 115. At 625-a, the network entity 105-k may receive an uplink reference signal from the UE 115-n on the RC-IMR set associated with the first RC-IMR configuration. At 625-b, the network entity 105-l may receive an uplink reference signal from the UE 115-o on the RC-IMR set associated with the second RC-IMR configuration. In some examples, the uplink reference signal from UE 115 - n and the uplink reference signal from UE 115 - o may be associated with different orthogonal cover codes.

[0152] At 630, the network entity 105 may perform interference measurements associated with the one or more RISs based on receiving an uplink reference signal from the UE 115. At 630-a, the network entity 105-k may perform a first set of interference measurements associated with the one or more RISs based on receiving an uplink reference signal from the UE 115-n on a RC-IMR set associated with the first RC-IMR configuration. At 630-b, the network entity 105-l may perform a second set of interference measurements associated with the one or more RISs based on receiving an uplink reference signal from the UE 115-o on a RC-IMR set associated with the second RC-IMR configuration.

[0153] At 635, the network entity 105 may jointly determine a second activation schedule (e.g., an optimal set of directional settings, active periods, and inactive periods) for one or more RIS based on the first interference measurement set and the second interference measurement set. In some examples, the network entity 105-k may send a control message to the network entity 105-1 indicating the first interference measurement set performed by the network entity 105-k. Similarly, the network entity 105-1 may send a control message to the network entity 105-k indicating the second interference measurement set performed by the network entity 105-1. The network entity 105 may determine the second activation schedule based on exchanging these control messages. Additionally or alternatively, the network entity 105 may determine an appropriate resource allocation for communicating with the UE 115 based on the first interference measurement set and the second interference measurement set.

[0154] In some examples, network entity 105 may send an indication of the second activation schedule to RIS controller 605. Accordingly, RIS controller 605 may reconfigure one or more RISs based on the second activation schedule. In some examples, RIS controller 605 may send a control message to network entity 105 indicating an updated activation schedule (e.g., directional settings, inactive periods, active periods) for one or more RISs. The updated activation schedule may be the same as or different from the second activation schedule determined by network entity 105. Network entity 105 may schedule communications with UE 115 based on the updated configuration of the one or more RISs.

[0155] The process flow 600 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable the network entity 105 and the RIS controller 605 to jointly determine an optimal RIS configuration or a suitable allocation of resources for communicating with the UE 115 based on exchanging (e.g., communicating) interference measurements associated with one or more RISs. The optimal RIS configuration and the suitable allocation of resources may reduce RIS-centric interference (e.g., interference caused by one or more RISs) and increase the likelihood that the network entity 105 can successfully communicate with the UE 115 via the one or more RISs.

[0156] Figure 7 An example of a wireless communication system 700 supporting interference management for RIS according to aspects of the present disclosure is illustrated. The wireless communication system 700 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, the wireless communication system 301, the wireless communication system 400, the process flow 500, or the process flow 600. For example, the wireless communication system 700 may include a network entity 105-m, a network entity 105-n, a network entity 105-o, a UE 115-p, a UE 115-q, a UE 115-r, a UE 115-s, a UE 115-t, and a UE 115-u, which may be reference 105-n, 105-n, 105-o, 105-n, 105-r, 105-s, 105-t, and 105-u. Figures 1 to 6 The wireless communication system 700 may also include RIS 710-a, RIS 710-b, and RIS 710-c, which may be reference Figures 2 to 4 The examples of RIS 210, RIS 310 or RIS 410 are described. In the wireless communication system 700, the network entity 105 can communicate via one or more backhaul connections (eg, Xn interfaces) to determine an optimal activation schedule for the RIS 710.

[0157] In the wireless communication system 700, the RIS 710 may be controlled by the network entity 105 (e.g., rather than a central RIS controller). Each of the network entities 105 may manage one or more of the RIS 710 using an independent RIS activation schedule (e.g., on / off times). For example, the network entity 105-m may control the RIS 710-a, the network entity 105-n may control the RIS 710-b, and the network entity 105-o may control the RIS 710-c. According to aspects of the present disclosure, the network entity 105 may negotiate (e.g., over an X2 interface) to determine appropriate RIS parameters (e.g., RIS beamforming weights, on / off times) for the RIS 710. The network entity 105 may also jointly configure the RC-IMR of the UE 115 served by the network entity 105 (e.g., so that the UE 115 can measure interference from the RIS 710).

[0158] In some examples, the network entity 105 may exchange RIS configuration parameters (e.g., RIS beamforming weights, RIS on / off periods), and may determine appropriate RIS configurations (e.g., activation schedules) for each of the RIS 710 based on the exchange of these RIS configuration parameters. The network entity 105 may also jointly determine the RC-IMR based on the determined RIS configurations of each of the RIS 710. In some examples, these RC-IMRs may correspond to different combinations of RIS beamforming weights and activation modes of the RIS 710. The network entity 105 may configure the RIS 710 with different beamforming weights and activation modes in a specific time-frequency resource so that the UE 115 may perform interference measurements for different RIS configurations. For each time-frequency resource in the RC-IMR set, the UE 115 may perform interference measurements associated with the RIS 710.

[0159] UE 115 may generate interference measurement information based on performing measurements of downlink reference signals associated with network entity 105. Similarly, UE 115 may generate interference measurement information based on performing measurements of uplink reference signals associated with UE 115. As described herein, a reference signal associated with a network node may refer to a reference signal sent by (e.g., originated at) the network node, and such reference signal may be received by one or more other network nodes directly from the network node or indirectly via one or more RISs (e.g., one or more RISs 710). Reference signals received indirectly via a RIS may, for example, be reflected or refracted by the RIS.

[0160] In some examples, UE 115 may report interference measurement information to network entity 105. UE 115 may perform one or more measurements to generate the reported interference measurement information. The interference measurement information reported by UE 115 may be information measured by UE 115 (e.g., UE 115 may perform measurements to measure RSRP values ​​and report the measured RSRP values). Additionally or alternatively, the interference measurement information reported by UE 115 may be derived from information measured by UE 115 (e.g., UE 115 may report an SNR value, which UE 115 may derive from one or more measurement values).

[0161] The wireless communication system 700 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable the network entity 105 to jointly determine an optimal RIS configuration for the RIS 710 or a suitable allocation of resources for communicating with the UE 115 based on exchanging (e.g., communicating) interference measurements associated with the RIS 710. The optimal RIS configuration and the suitable allocation of resources may reduce interference caused by the RIS 710 and increase the likelihood that the network entity 105 will successfully communicate with the UE 115 via the RIS 710.

[0162] Figure 8 An example of a process flow 800 for supporting interference management for RIS according to aspects of the present disclosure is illustrated. The process flow 800 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, the wireless communication system 301, the wireless communication system 400, the process flow 500, the process flow 600, or the wireless communication system 700. For example, the process flow 800 may include the network entity 105-p, the network entity 105-q, the UE 115-v, and the UE 115-w, which may be reference Figures 1 to 7 The process flow 800 may also include RIS 810-a and RIS 810-b, which may be reference Figures 2 to 7 Examples of RIS 210, RIS 310, RIS 410, or RIS 710 are described. In the following description of process flow 800, operations between network entity 105, UE 115, and RIS 810 may be performed in a different order or at a different time than shown. Additionally or alternatively, some operations may be omitted from process flow 800 and other operations may be added to process flow 800.

[0163] At 815, network entity 105-p may perform a RIS schedule negotiation procedure with network entity 105-q. For example, network entity 105-p may send a control message to network entity 105-q indicating a first set of directional settings for RIS 810, a first set of active periods for RIS 810, or a first set of inactive periods for RIS 810. Similarly, network entity 105-q may send a control message to network entity 105-p indicating a second set of directional settings for RIS 810, a second set of active periods for RIS 810, or a second set of inactive periods for RIS 810. Network entity 105 may determine a first activation schedule (e.g., an initial activation schedule) for RIS 810 based on the control messages.

[0164] At 820, network entity 105-p may perform an RC-IMR configuration negotiation procedure with network entity 105-q. In some examples, network entity 105 may perform the RC-IMR configuration negotiation procedure over a backhaul connection (e.g., an Xn interface). During the RC-IMR configuration negotiation procedure, network entity 105-p may send a control message indicating a first potential RC-IMR set to network entity 105-q. Similarly, network entity 105-q may send a control message indicating a second potential RC-IMR set to network entity 105-p. Network entity 105 may jointly determine an RC-IMR configuration (e.g., a final RC-IMR set) based on exchanging these control messages.

[0165] At 825, the network entity 105 may send a RIS control message to the RIS 810 based on the determined RC-IMR configuration and the first activation schedule. For example, the network entity 105-p may send a first RIS control message to the RIS 810-a at 825-a. The first RIS control message may indicate a set of directional settings for the RIS 810-a, a set of active periods for the RIS 810-a, or a set of inactive periods for the RIS 810-a. Similarly, the network entity 105-q may send a second RIS control message to the RIS 810-b at 825-b. The second RIS control message may indicate a set of directional settings for the RIS 810-b, a set of active periods for the RIS 810-b, or a set of inactive periods for the RIS 810-b.

[0166] At 830-a, network entity 105-p may send an indication of the RC-IMR configuration (e.g., the location of the RC-IMR) to UE 115-v. At 830-b, network entity 105-q may send an indication of the RC-IMR configuration to UE 115-w. Thus, network entity 105 may send one or more downlink reference signals to UE 115 on the RC-IMR associated with the RC-IMR configuration. For example, network entity 105-p may send one or more downlink reference signals to UE 115-v on a first RC-IMR set, and network entity 105-q may send one or more downlink reference signals to UE 115-w on a second RC-IMR set. In some examples, each RC-IMR may correspond to a respective combination of an active RIS and an inactive RIS.

[0167] UE 115 may perform interference measurements associated with RIS 810 based on receiving one or more downlink reference signals from network entity 105. For example, UE 115 may measure RSRP of one or more downlink reference signals. Accordingly, UE 115 may generate corresponding measurement reports indicating these interference measurements and may send corresponding measurement reports to network entity 105. For example, UE 115-v may send the measurement report to network entity 105-p at 835-a. Similarly, UE 115-w may send the measurement report to network entity 105-q at 835-b.

[0168] At 840, network entity 105 may determine a second activation schedule (e.g., an optimal RIS configuration) for RIS 810 or a suitable allocation of resources for communicating with UE 115 based on the measurement report from UE 115. In some examples, network entity 105-p may send a control message indicating interference measurements performed by UE 115-v to network entity 105-q. Similarly, network entity 105-q may send a control message indicating interference measurements performed by UE 115-w to network entity 105-p. Network entity 105 may jointly determine a second activation schedule for RIS 810 and a suitable allocation of resources for communicating with UE 115 based on exchanging these control messages.

[0169] At 845, the network entity 105 may configure the RIS 810 with the second activation schedule. For example, at 845-a, the network entity 105-q may configure the RIS 810-b with the set of directional settings, the set of active periods, and the set of inactive periods associated with the second activation schedule. Similarly, at 845-b, the network entity 105-p may configure the RIS 810-a with the set of directional settings, the set of active periods, and the set of inactive periods associated with the second activation schedule. Additionally or alternatively, the network entity 105 may schedule communications with the UE 115 using the appropriate allocation of resources determined at 840. For example, the network entity 105-p may schedule communications with the UE 115-v on the first set of time and frequency resources, and the network entity 105-q may schedule communications with the UE 115-w on the second set of time and frequency resources.

[0170] Process flow 800 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable network entity 105 to jointly determine an optimal RIS configuration for RIS 810 or a suitable allocation of resources for communicating with UE 115 based on exchanging (e.g., communicating) interference measurements associated with RIS 810. The optimal RIS configuration and the suitable allocation of resources may reduce interference caused by RIS 810 and increase the likelihood that network entity 105 will successfully communicate with UE 115 via RIS 810.

[0171] Fig. 9 An example of a process flow 900 supporting interference management for RIS according to aspects of the present disclosure is illustrated. The process flow 900 may implement or be implemented by aspects of the wireless communication system 100, the wireless communication system 200, the wireless communication system 300, the wireless communication system 301, the wireless communication system 400, the process flow 500, the process flow 600, the wireless communication system 700, or the process flow 800. For example, the process flow 900 may include the network entity 105-r, the network entity 105-s, the UE 115-x, and the UE 115-y, which may be reference Figures 1 to 8 The process flow 900 may also include RIS 910-a and RIS 910-b, which may be reference Figures 2 to 8 Examples of RIS 210, RIS 310, RIS 410, RIS 710, or RIS 810 are described. In the following description of process flow 900, operations between network entity 105, UE 115, and RIS 910 may be performed in a different order or at a different time than shown. Additionally or alternatively, some operations may be omitted from process flow 900 and other operations may be added to process flow 900.

[0172] At 915, the network entity 105-r may perform a RIS schedule negotiation procedure with the network entity 105-s. For example, the network entity 105-r may send a control message to the network entity 105-s, the control message indicating a first set of directional settings for the RIS 910, a first set of active periods for the RIS 910, or a first set of inactive periods for the RIS 910. Similarly, the network entity 105-s may send a control message to the network entity 105-r, the control message indicating a second set of directional settings for the RIS 910, a second set of active periods for the RIS 910, or a second set of inactive periods for the RIS 910. The network entity 105 may determine a first activation schedule (e.g., an initial activation schedule) for the RIS 910 based on these control messages.

[0173] At 920, the network entity 105-r may perform an RC-IMR configuration negotiation procedure with the network entity 105-s. In some examples, the network entity 105 may perform the RC-IMR configuration negotiation procedure over a backhaul connection (e.g., an Xn interface). During the RC-IMR configuration negotiation procedure, the network entity 105-r may send a control message indicating a first potential RC-IMR set to the network entity 105-s. Similarly, the network entity 105-s may send a control message indicating a second potential RC-IMR set to the network entity 105-r. The network entity 105 may jointly determine the RC-IMR configuration (e.g., a final RC-IMR set) based on exchanging these control messages.

[0174] At 925, the network entity 105 may send a RIS control message to the RIS 910 based on the determined RC-IMR configuration and the first activation schedule. For example, the network entity 105-r may send a first RIS control message to the RIS 910-a at 925-a. The first RIS control message may indicate a set of directional settings for the RIS 910-a, a set of active periods for the RIS 910-a, or a set of inactive periods for the RIS 910-a. Similarly, the network entity 105-s may send a second RIS control message to the RIS 910-b at 925-b. The second RIS control message may indicate a set of directional settings for the RIS 910-b, a set of active periods for the RIS 910-b, or a set of inactive periods for the RIS 910-b.

[0175] At 930-a, the network entity 105-r may send an indication of the RC-IMR configuration (e.g., RC-IMR position) to the UE 115-x. At 930-b, the network entity 105-s may send an indication of the RC-IMR configuration to the UE 115-y. Thus, the network entity 105 may receive one or more uplink reference signals from the UE 115 on the RC-IMR associated with the RC-IMR configuration. For example, the network entity 105-r may receive one or more uplink reference signals from the UE 115 on the first RC-IMR set at 935-a, and the network entity 105-s may receive one or more uplink reference signals from the UE 115-y on the second RC-IMR set at 935-b. In some examples, each RC-IMR may correspond to a corresponding combination of an active RIS (e.g., an active RIS) and an inactive RIS (e.g., an inactive RIS).

[0176] The network entity 105 may perform interference measurements associated with the RIS 910 based on receiving one or more uplink reference signals from the UE 115 on the RC-IMR. For example, the network entity 105-r may perform an interference measurement set at 940-a on the uplink reference signal received from the UE 115-x. Similarly, the network entity 105-s may perform an interference measurement set at 940-b on the uplink reference signal received from the UE 115-y. In some examples, the interference measurement set may include, for example, the RSRP of the one or more uplink reference signals.

[0177] At 945, the network entity 105 may determine a second activation schedule (e.g., an optimal RIS configuration) for the RIS 910 or a suitable allocation of resources for communicating with the UE 115 based on the interference measurements performed at 940. In some examples, the network entity 105-r may send a control message indicating the interference measurements performed by the network entity 105-r to the network entity 105-s. Similarly, the network entity 105-s may send a control message indicating the interference measurements performed by the network entity 105-s to the network entity 105-r. The network entity 105 may jointly determine a second activation schedule for the RIS 910 and a suitable allocation of resources for communicating with the UE 115 based on exchanging these control messages.

[0178] At 950, the network entity 105 may configure the RIS 910 with the second activation schedule. For example, at 950-a, the network entity 105-s may configure the RIS 910-b with the set of directional settings, the set of active periods, and the set of inactive periods associated with the second activation schedule. Similarly, at 950-b, the network entity 105-r may configure the RIS 910-a with the set of directional settings, the set of active periods, and the set of inactive periods associated with the second activation schedule. Additionally or alternatively, the network entity 105 may schedule communications with the UE 115 using the appropriate allocation of resources determined at 945. For example, the network entity 105-r may schedule communications with the UE 115-x on the first set of time and frequency resources, and the network entity 105-s may schedule communications with the UE 115-y on the second set of time and frequency resources.

[0179] The process flow 900 may support techniques for reducing RIS-centric interference and improving communication reliability, among other benefits. For example, the techniques described herein may enable the network entity 105 to jointly determine one of an optimal RIS configuration for the RIS 910 or a suitable allocation of resources for communicating with the UE 115 based on exchanging (e.g., communicating) interference measurements associated with the RIS 910. The optimal RIS configuration and the suitable allocation of resources may reduce interference caused by the RIS 910 and increase the likelihood that the network entity 105 will successfully communicate with the UE 115 via the RIS 910.
