Technical Field

[0003] The following discussion relates to wireless communication, including techniques for determining channel measurements using repeaters controlled by a network. Background Technology

[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, message sending and receiving, and broadcasting. These systems can 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, LTE-A Advanced (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 technologies such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal FDMA (OFDMA), or Discrete Fourier Transform Extended Orthogonal Frequency Division Multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UE).

[0036] Some wireless communication systems may include a network-controlled repeater (NCR). An NCR may include an NCR forwarding (NCR-Fwd) functional entity and an NCR mobile terminal (NCR-MT) functional entity. The NCR-Fwd performs amplified forwarding of uplink and downlink radio frequency signals between the network entity and the user equipment (UE). The NCR-Fwd forwards multiple component carriers associated with the network entity. The NCR-MT communicates side-side control information, such as control and status signaling, to the network entity via a control link. The behavior of the NCR-Fwd can be controlled based on the side-side control information received by the NCR-MT from the network entity. In some examples, the UE may be configured by the network entity to perform channel measurements on different subbands of multiple component carriers associated with the network, and the UE may transmit the channel measurements to the network entity. The UE performing and reporting channel measurements may consume UE power and processing capabilities, and may incur signaling overhead.

[0037] The techniques described herein for determining channel measurements by the NCR can effectively utilize available resources. In some examples, the NCR may receive control signaling from a network entity via the serving cell associated with the NCR, indicating one or more subbands for channel measurements on component carriers associated with network-controlled forwarding. These one or more subbands may not overlap at least partially with the frequency range associated with the serving cell. The NCR may transmit the channel measurements associated with these one or more subbands to the network entity. The NCR may relay signaling on these one or more subbands in part based on the channel measurements. In some examples, the NCR may receive control signaling from a network entity indicating control information associated with network-controlled forwarding via one or more subbands. For example, the control information may indicate amplification gain, transmit power, switching operation, one or more return beams, one or more access link beams, the number of antenna elements, or combinations thereof. In some examples, the network entity may output control signaling to the UE, based on channel measurements and via network-controlled forwarding, indicating the configuration of frequency domain resources for communication.

[0038] The aspects of this disclosure are first described in the context of a wireless communication system. They are also described in the context of a process flow. The aspects of this disclosure are further illustrated and described by means of, and with reference to, apparatus diagrams, system diagrams, and flowcharts relating to techniques used for determining channel measurements by NCR.

[0039] Figure 1 An example of a wireless communication system 100 supporting techniques for determining channel measurements by NCR according to one or more aspects of this disclosure is shown. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a Long Term Evolution (LTE) network, an Advanced LTE (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating under other systems and radio technologies including future systems and radio technologies not explicitly mentioned herein.

[0040] Network entity 105 may be distributed across a geographical area to form wireless communication system 100, and may include devices employing different forms or having different capabilities. In various examples, network entity 105 may be referred to as a network element, mobility element, radio access network (RAN) node, or network equipment, etc. In some examples, network entity 105 and UE 115 may wirelessly communicate via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, network entity 105 may support coverage area 110 (e.g., a geographical coverage area) within which UE 115 and network entity 105 may establish one or more communication links 125. Coverage area 110 may be an example of a geographical area within which network entity 105 and UE 115 may support the transmission of signals according to one or more radio access technologies (RATs).

[0041] UE 115 can be distributed throughout the coverage area 110 of wireless communication system 100, and each UE 115 can be stationary or mobile, or stationary and mobile at different times. UE 115 can be devices in different forms or with different capabilities. Figure 1 Some example UE 115s are illustrated herein. The UE 115 described herein can be able to support various types of devices (such as, e.g., ...). Figure 1 It communicates with other UEs (115 or network entity 105) as shown.

[0042] As described herein, a node in the wireless communication system 100 (which may be referred to as a network node or 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, apparatus, device, computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be UE 115. As another example, a node may be 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 UE 115, the second node may be network entity 105, and the third node may be UE 115. In another aspect of this example, the first node may be UE 115, the second node may be network entity 105, and the third node may be network entity 105. In other aspects of this example, the first node, the second node, and the third node may be different from these examples. Similarly, references to UE 115, network entity 105, device, equipment, computing system, etc., may include disclosures of UE 115, network entity 105, device, equipment, computing system, etc., as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that a first node is configured to receive information from a second node.

[0043] In some examples, network entity 105 may communicate with core network 130, communicate with each other, or both. For example, network entity 105 may communicate with 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, network entities 105 may communicate with each other directly (e.g., directly between network entities 105) or indirectly (e.g., via core network 130) via backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, network entities 105 may communicate with each other via midhaul communication link 162 (e.g., according to midhaul interface protocol) or fronthaul communication link 168 (e.g., according to fronthaul interface protocol) or any combination thereof. The backhaul communication link 120, midhaul communication link 162, or fronthaul communication link 168 may be one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof, or may include one or more wired links (e.g., electrical links, fiber optic links), one or more wireless links (e.g., radio links, wireless optical links), etc., or various combinations thereof. UE 115 may communicate with the core network 130 via communication link 155.

[0044] One or more network entities in network entity 105 described herein may include or be referred to as base station 140 (e.g., transceiver base station, radio base station, NR base station, access point, radio transceiver, node B, eNodeB (eNB), next-generation node B or gigabit node B (any of which may be referred to as gNB), 5G NB, next-generation eNB (ng-eNB), home node B, home evolution node B, or other suitable terms). In some examples, network entity 105 (e.g., base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture that may be configured to utilize a protocol stack that is physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as base station 140).

[0045] In some examples, network entity 105 may be implemented in a decomposed architecture (e.g., a decomposed base station architecture, a decomposed RAN architecture) that can be configured to utilize protocol stacks physically or logically distributed across two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC, a non-real-time RIC), a service management and orchestration (SMO) 180 system, or any combination thereof. 170 may also be referred to as a radio headend, intelligent radio headend, remote radio headend (RRH), remote radio unit (RRU), or transmit / receive point (TRP). One or more components of network entity 105 in a decomposed RAN architecture may be co-located, or one or more components of network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 in a decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).

[0046] The functional splitting among CU 160, DU 165, and RU 170 is flexible and can support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a protocol stack functional splitting can be used between CU 160 and DU 165, allowing CU 160 to support one or more layers of the protocol stack, and DU 165 to support one or more different layers of the protocol stack. In some examples, CU 160 can host higher protocol layer (e.g., Layer 3 (L3), Layer 2 (L2)) functionalities and signaling (e.g., Radio Resource Control (RRC), Serving Data Adaptation Protocol (SDAP), Packet Data Convergence Protocol (PDCP)). CU 160 can connect to one or more DU 165 or RU 170, and one or more DU 165 or RU 170 can 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 each can be at least partially controlled by CU 160. Additionally or alternatively, a protocol stack functional split can be employed between DU 165 and RU 170, such that DU 165 can support one or more layers of the protocol stack, and RU 170 can support one or more different layers of the protocol stack. DU 165 can support one or more different cells (e.g., via one or more RU 170). In some cases, functional decomposition between CU 160 and DU 165, or between DU 165 and RU 170, can be performed within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer can be performed by different of CU 160, DU 165, or RU 170). CU 160 can be further functionally decomposed into CU control plane (CU-CP) functions and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DU 165 via midhaul communication link 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RU 170 via fronthaul communication link 168 (e.g., open fronthaul (FH) interface). In some examples, the midhaul communication link 162 or the fronthaul communication link 168 may be implemented based on the interfaces (e.g., channels) between the layers of the protocol stack, which are supported by the corresponding network entities 105 communicating via such communication links.

[0047] In a wireless communication system (e.g., wireless communication system 100), the infrastructure and spectrum resources for radio access can 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 node 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 DU 165s or one or more RU 170s may be partially controlled by one or more CU 160s associated with donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB node 104) via supported access and backhaul links (e.g., backhaul communication link 120). IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a DU 165 of a coupled IAB donor. The IAB-MT may include a separate set of antennas for relaying communication with UE 115, or may share the same antennas (e.g., those of RU 170) for access to IAB node 104 via DU 165 of IAB node 104. (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, 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 IAB node 104) may be configured to operate according to the techniques described herein.

[0048] In the context of applying the techniques described herein to a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support techniques as described herein for determining channel measurements by NCR. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may additionally or alternatively be performed by one or more components of the decomposed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).

[0049] UE 115 may include or be referred to as a mobile device, wireless device, remote device, handheld device, or subscriber device, or any other suitable term, wherein "device" may also be referred to as a cell, station, terminal, or client, etc. UE 115 may also include or be referred to as a personal electronic device, such as a cellular phone, personal digital assistant (PDA), tablet computer, laptop computer, or personal computer. In some examples, UE 115 may include or be referred to as a wireless local loop (WLL) station, Internet of Things (IoT) device, Internet of Everything (IoE) device, or machine-type communication (MTC) device, etc., which may be implemented in various objects such as appliances or vehicles, meters, etc.

[0050] The UE 115 described herein can communicate with various types of devices, such as other UEs 115 that sometimes act as relays, network entities 105, and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 As shown. UE 115 can communicate with network entity 105 via NCR 185.

[0051] UE 115 and network entity 105 can 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" can refer to a set of RF spectrum resources having a defined physical layer structure for supporting communication link 125. For example, a carrier for communication link 125 may include a portion of the RF spectrum band (e.g., a bandwidth portion (BWP)) operating 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 coordinating carrier operation, user data, or other signaling. Wireless communication system 100 can support communication with UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, UE 115 can be configured using multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation can be used in conjunction with both frequency division duplex (FDD) component carriers and time division duplex (TDD) component carriers. Communication between network entity 105 and other devices can refer to communication between these devices and any part of network entity 105 (e.g., entity, sub-entity). For example, the terms “send,” “receive,” or “communicate” when referring to network entity 105 can refer to any part of the RAN’s network entity 105 (e.g., base station 140, CU160, DU 165, RU 170) communicating with another device (e.g., directly or via one or more other network entities 105).

[0052] The signal waveform transmitted via a carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform extended OFDM (DFT-S-OFDM)). In a system employing MCM, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and 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, the decoding rate of the modulation scheme, or both), such that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high modulation scheme order correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, temporal 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.

[0053] The time interval for network entity 105 or UE 115 can be expressed as a multiple of a basic time unit, such as the sampling period. seconds, of which It can represent the supported subcarrier spacing, and This can represent the supported Discrete Fourier Transform (DFT) size. The time interval of the communication resources can be organized according to radio frames, each with a specified duration (e.g., 10 milliseconds (ms)). Each radio frame can be identified by a System Frame Number (SFN) (e.g., ranging from 0 to 1023).

[0054] 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, a frame may (e.g., in the time domain) be divided into subframes, and each subframe may be further divided into a number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a number of symbol periods (e.g., depending on the length of the cyclic prefix appended to each symbol period). In some wireless communication systems 100, time slots may be further divided into multiple 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., The duration of a symbol period is associated with a (number) sampling period. The duration of a symbol period can depend on the subcarrier spacing or the operating frequency band.

[0055] A subframe, time slot, micro-time slot, or symbol can be the smallest scheduling unit of the wireless communication system 100 (e.g., in the time domain) and can be referred to as a transmission time interval (TTI). In some examples, the duration of the TTI (e.g., the number of symbol periods in the TTI) can be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 can be dynamically selected (e.g., in a burst of shortened TTIs (sTTIs)).

[0056] Depending on the technology, carriers can be used to multiplex physical channels for communication. One or more of Time Division Multiplexing (TDM), Frequency Division Multiplexing (FDM), or hybrid TDM-FDM techniques can be used, for example, to multiplex physical control channels and physical data channels for signaling via a downlink carrier. The control region (e.g., control resource set (CORESET)) of the physical control channel can be defined by a set of symbol periods and can extend across the system bandwidth of the carrier or a subset of that bandwidth. One or more control regions (e.g., CORESET) can be configured for a set of UEs 115. For example, one or more UEs in UE 115 can monitor or search for control regions to obtain control information based on one or more search space sets, and each search space set can include one or more control channel candidates in one or more aggregation levels arranged in a concatenated manner. The aggregation level of control channel candidates can 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 set may include: a common search space set configured to transmit control information to multiple UEs 115, and a UE-specific search space set used to transmit control information to a specific UE 115.

[0057] In some examples, network entity 105 (e.g., base station 140, RU 170) may be mobile, and thus provide communication coverage to 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 use the same or different radio access technologies to provide coverage for various coverage areas 110.

[0058] Wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication, or various combinations thereof. For example, wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communication may include private 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 prioritizing services, and such services may be used for public safety or general business applications. The terms “ultra-reliable,” “low-latency,” and “ultra-reliable low-latency” are used interchangeably herein.

[0059] In some examples, UE 115 may be configured to support direct communication with other UE 115s via device-to-device (D2D) communication link 135 (e.g., according to peer-to-peer (P2P), D2D, or sidelink protocols). In some examples, one or more UE 115s performing D2D communication in a group may be within the coverage area 110 of network entity 105 (e.g., base station 140, RU 170), which may support aspects of such D2D communication configured (e.g., scheduled by network entity 105). In some examples, one or more UE 115s in this group may be outside the coverage area 110 of network entity 105, or may otherwise be unable or not configured to receive transmissions from network entity 105. In some examples, the group of UE 115s communicating via D2D communication may support a one-to-many (1:M) system, where each UE 115 transmits to each of the other UE 115s in the group. In some examples, network entity 105 may facilitate the scheduling of resources used for D2D communication. In other examples, D2D communication may be performed between UEs 115 without involving network entity 105.

[0060] Core network 130 provides user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. Core network 130 can 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), 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), packet data network (PDN) gateway (P-GW), or user plane function (UPF)) for routing packets or interconnecting to external networks. The control plane entity manages non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by network entity 105 (e.g., base station 140) associated with core network 130. User IP packets can be transferred through user plane entities, which provide IP address allocation and other functions. User plane entities can connect to one or more network operator IP services 150. IP services 150 may include access to the Internet, intranets, IP Multimedia Subsystem (IMS), or packet-switched streaming services.

[0061] Wireless communication system 100 can operate using one or more frequency bands in the range of 300 MHz to 300 GHz. Generally, the area from 300 MHz to 3 GHz is referred to as the Ultra High Frequency (UHF) band or decimeter band because the wavelength range is approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves are sufficient to penetrate structures so that macrocells can provide service to UE 115 located indoors. Compared to communication using smaller frequencies and longer wavelengths in the lower frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz, communication using UHF waves can be associated with smaller antennas and shorter ranges (e.g., less than 100 km).

[0062] Wireless communication system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, wireless communication system 100 may use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ Licensed Assisted Access (LAA), LTE Unlicensed (LTE-U) radio access technology, or NR technology. When operating with unlicensed RF spectrum, devices such as network entity 105 and UE 115 may employ carrier sensing for collision detection and avoidance. In some examples, operation using unlicensed bands may be combined with component carriers operating with licensed bands based on carrier aggregation configurations (e.g., LAA). Operation using unlicensed spectrum may include downlink transmission, uplink transmission, P2P transmission, or D2D transmission, etc.

[0063] 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 techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of network entity 105 or UE 115 may be located within one or more antenna arrays or antenna panels, which can support MIMO operation 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, the antennas or antenna arrays associated with network entity 105 may be located at different geographical locations. Network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that network entity 105 can use to support beamforming for communication with UE 115. Similarly, UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals transmitted via the antenna ports.

[0064] Beamforming (also known as spatial filtering, directional transmission, or directional reception) is a signal processing technique that can be used at a transmitting or receiving device (e.g., network entity 105, UE 115) to shape or guide an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting and receiving devices. Beamforming can be achieved by combining signals transmitted via antenna elements of an antenna array such that some signals propagating along a specific orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to the signals transmitted via the antenna elements may include applying amplitude shifts, phase shifts, or both to the signals carried via the antenna elements associated with the device. The adjustments associated with each of these antenna elements may be defined by a beamforming weight set associated with a specific orientation (e.g., relative to the antenna array of the transmitting or receiving device or relative to some other orientation).

[0065] Some wireless communication systems may include an NCR. An NCR may include an NCR-Fwd functional entity and an NCR-MT functional entity. The NCR-Fwd performs amplification and forwarding of uplink and downlink radio frequency signals between network entity 105 and the UE. The NCR-Fwd forwards multiple component carriers associated with network entity 105. The NCR-MT communicates side-side control information, such as control and status signaling, to network entity 105 via a control link. The behavior of the NCR-Fwd can be controlled based on the side-side control information received by the NCR-MT from network entity 105. In some examples, UE 115 may be configured by network entity 105 to perform channel measurements on different subbands of multiple component carriers associated with the network, and UE 115 may send channel measurements to network entity 105. UE 115 performing and reporting channel measurements may consume UE 115's power and processing capabilities, and may incur signaling overhead.

[0066] The techniques used for determining channel measurements by the NCR can effectively utilize available resources. In some examples, the NCR may receive control signaling from network entity 105 via the serving cell associated with the NCR, indicating one or more subbands for channel measurements on component carriers associated with network control forwarding. These one or more subbands may not overlap at least partially with the frequency range associated with the serving cell. The NCR may transmit the channel measurements associated with these one or more subbands to the network entity. The NCR may relay signaling on these one or more subbands based on the channel measurements. In some examples, the NCR may receive control signaling from the network entity indicating control information, which may be associated with the forwarding of network control via one or more subbands. For example, the control information may indicate amplification gain, transmit power, switching operation, one or more return beams, one or more access link beams, the number of antenna elements, or combinations thereof. In some examples, network entity 105 may output control signaling to UE 115, based on channel measurements and via network control forwarding, indicating the configuration of frequency domain resources for communication.

[0067] Figure 2 An example of a wireless communication system 200 supporting techniques for determining channel measurements by NCR, according to one or more aspects of this disclosure, is shown. The wireless communication system 200 can implement, as in... Figure 1 The aspects of the wireless communication system 100 described herein may be implemented by aspects of the wireless communication system. For example, the wireless communication system 200 may support signaling and configuration for determining channel measurements by NCR. The wireless communication system 200 may include network entity 105-a and UE 115-a, which may be as described in reference Figure 1 Examples of network entity 105 and UE 115 described.

[0068] In some examples, wireless communication system 200 may include NCR 205, and NCR 205 may include NCR-MT 210 and NCR-Fwd 215. In some aspects, network entity 105-a may communicate with NCR-MT 210 via control link 220. UE 115-a may communicate with network entity 105-a via access link 230 (e.g., Uu link) and backhaul link 225. NCR-Fwd 215 may perform amplification and forwarding of uplink and downlink radio frequency signals (e.g., uplink control signals, uplink data signals, downlink control signals, and downlink data signals) between network entity 105-a and UE 115-a via backhaul link 225 and access link 230. The connection between network entity 105-a and UE 115-a via NCR 205 may be regarded as UE access link 235, and NCR 205 may be transparent to UE 115-a. Additionally, the links between network entity 105-a and NCR 205, and between NCR 205 and UE 115-a, can be maintained simultaneously. NCR-MT 210 can exchange side-side control information with network entity 105-b via control link 220, which can be based on the NR Uu interface. The behavior of NCR-Fwd 215 can be controlled based on the side-side control information received by NCR-MT 210 from network entity 105-a. NCR 205 can provide an in-band RF repeater for coverage extension on FR1 or FR2, or both, and forwarding performed by NCR 205 can be single-hop. NCR 205 can be stationary or mobile.

[0069] The behavior of NCR-Fwd 215 can be controlled based on side-side control information received by NCR-MT 210 from network entity 105-b. In some examples, the side-side control information or configuration exchanged between network entity 105-b and NCR-MT 210 may include one or more of the following: beam information for access link 230 and backhaul link 225, TDD uplink or downlink configuration, and switching indications for NCR-Fwd 215. For example, the side-side control information may include access link beam indications, such as aperiodic beam indications via downlink control information (DCI) and RRC, semi-persistent beam indications via medium access control-control element (MAC-CE) and RRC, or periodic beam indications via RRC. Access link beam indications may indicate one or more beam indices and associated time resources. Access beam indications may include beam indices indexed by orbital angular momentum (OAM) configuration of the access beam. Side-link control information may include return beam indications, such as semi-persistent optional beam indications that can be provided via MAC-CE. Optional beam indications may include beam indices of beams indexed by the RRC configuration of the NCR-MT 210. In the absence of explicit indications, return beam indications may include predefined rules. In some cases, side-link control information may include a switch indication for the NCR-Fwd 215, where an "on" state is implicitly indicated via the access link beam indication, and the NCR-Fwd may be in an "off" state if not indicated as "on" or within a semi-static flexible symbol. In some cases, when no new side-link control information is provided, the TDD information of the NCR-Fwd 215, as well as transmit and receive timing references, may be provided by the available information of the NCR-MT 210. The access link beam configuration information of the NCR-Fwd 215 may be provided by the OAM, which includes information characterizing the beams to network entities 105-a and NCR 205. In some cases, beam characterization (e.g., the number of beams, spatial information, and orientation) can depend on the specific implementation.

[0070] In some examples, frequency-selective carriers may include different sub-bands with different channel conditions. Within the existing Channel State Information (CSI) framework, UE 115-a may be configured by network entity 105-a to perform channel measurements on different sub-bands and report these measurements to network entity 105-a. A sub-band may be a frequency range, a radio frequency band, a component carrier, or a bandwidth portion of a component carrier. Using the reported channel measurements, network entity 105-a may perform frequency-selective scheduling, such as selecting one or more sub-bands with less interference for data communication. In some cases, network entity 105-a may perform frequency-dependent downlink power control (e.g., the classic water-filling method) based on the reported channel measurements.

[0071] In some examples, NCR-MT 210 may be configured by network entity 105-a to perform subband channel measurements, and the channel measurements performed by NCR-MT 210 may be performed on the serving cell of NCR-MT 210. Backhaul link 225 may partially overlap with or not overlap with the serving cell of NCR-MT 210, especially for out-of-band repeaters. NCR-Fwd 215 may forward multiple component carriers of network entity 105-a, and the serving cell of NCR-MT 210 may be one of the forwarded component carriers of network entity 105-a, or a subset of the forwarded component carriers of network entity 105-a (e.g., partially overlapping). In some cases, the serving cell of NCR-MT 210 may not overlap with the forwarded component carriers. For example, NCR-Fwd 215 may forward the FR2 component carrier of network entity 105-a, and NCR-MT 210 may connect to the FR1 cell (e.g., non-overlapping). In some examples, the techniques used for determining channel measurements by NCR 205 can support subband-based channel measurements on the backhaul link 225 of NCR-Fwd 215, and the backhaul link 225 may partially overlap with or not overlap with the serving cell of NCR-MT 210.

[0072] In some examples, network entity 105-a may select an initial subband for UE 115-a based on channel measurements or feedback from backhaul link 225 to save CSI feedback overhead for UE 115-a. For example, network entity 105-a may configure UE 115-a (or other UEs) to perform and report channel measurements on a subband with good channel conditions associated with backhaul link 225. For subbands with poor channel conditions on backhaul link 225, the end-to-end composite channel of UE access link 235 may also be poor. Backhaul link 225 may typically be stationary and may require less frequent channel measurement reporting than access link 230 of UE 115-a. The benefits of subband-based channel feedback from backhaul link 225 may include reduced power consumption of UE 115-a, simplified processing of UE 115-a, and reduced signaling overhead for UE 115-a.

[0073] In some examples, network entity 105-a may control its transmit power based on channel feedback associated with backhaul link 225 to avoid power amplifier (PA) saturation at NCR 205. Adjusting transmit power with network entity 105-a achieves the same goal using less transmit power compared to an alternative solution where NCR 205 autonomously adjusts its gain to avoid PA saturation. In some cases, network entity 105-a may perform frequency-dependent power control based on subband-based channel measurements on backhaul link 225. The benefits of subband-based channel feedback on backhaul link 225 can include saving network power and simplifying power implementation at NCR 205 (e.g., NCR 205 does not need to perform aggressive automatic gain control (AGC)).

[0074] In some examples, subband-based channel feedback of the backhaul link 225 can provide more efficient operation for the NCR 205, which has frequency shifting capabilities. For example, network entity 105-a can transmit a signal on a first subband (e.g., the strongest backhaul subband) selected based on the channel feedback for the backhaul link 225, and network entity 105-a can send a signaling message to the NCR 205 requesting the NCR 205 to shift the frequency to a second subband for access link 230 (e.g., the strongest subband of access link 230). The benefits of subband-based channel feedback of the backhaul link 225 can be higher resource utilization and higher spectral efficiency achieved.

[0075] In some examples, network entity 105-a can leverage advanced frequency-dependent forwarding capabilities based on channel feedback from backhaul link 225 to achieve more efficient subband-based control of NCR 205. NCR 205 may have advanced frequency-dependent forwarding capabilities; for example, NCR 205 may have one or more filters that can separate signals in the frequency domain at granularity such as RF bands, RF component carriers, or portions of component carriers (e.g., bandwidth portions). Although frequency-dependent forwarding can be performed autonomously by NCR 205, network-based control can be more efficient because network entity 105-a may have more information than NCR 205 to improve system performance. For example, network entity 105-a may have both end-to-end channel feedback from UE 115-a (or other UEs) and backhaul link channel feedback from NCR-MT 210. Additionally, network entity 105-a has a better understanding of interference between its scheduled direct or indirect UEs and the NCRs under its control. In addition, network entity 105-a can also obtain coordination messages from other network entities for interference control.

[0076] In some cases, network entity 105-a may determine different parameters of the NCR forwarding function in different subbands based on channel feedback from backhaul link 225 to maximize performance metrics. For example, performance metrics may be end-to-end signal-to-interference-plus-noise ratio (SINR), spectral efficiency, and network energy efficiency (including the energy efficiency of network entity 105-a, NCR 205, or UE 115-a). Based on channel measurement reports from UE 115-a (or other remote UE), NCR 205, or a combination thereof, network entity 105-a may decide to schedule direct UEs in the first subband and indirect UEs via NCR 205 in the second subband to improve system spectral efficiency. For example, network entity 105-a may send control signaling to control NCR 205 to enable forwarding for the second subband.

[0077] In some examples, NCR 205 can be configured to perform subband-based channel measurements on the backhaul link 225 of NCR-Fwd 215. For example, NCR 205 may receive control signaling 240 from network entity 105-a, which indicates one or more subbands for channel measurements on component carriers associated with forwarding for network control. These one or more subbands may at least partially overlap with, or may not overlap with, the frequency range associated with the serving cell of NCR-MT 210. NCR-MT 210 may send the subband-based channel measurements to network entity 105-a. In some examples, network entity 105-a may send a measurement configuration for the channel measurements. The measurement configuration may include one or more of the following: the signal to be measured, frequency domain information, the measurement quantity, or the time window for the measurement. For example, the signal to be measured may be a dedicated reference signal or a signal to be forwarded by NCR-Fwd 215. The frequency domain information may be the total bandwidth, subband granularity, or the number of subbands. In some cases, subband granularity can be a portion of the total bandwidth, such as an RF band, an RF component carrier, a portion of the component carrier bandwidth, or any configured frequency range. The measured quantity can be one or more of the following: Received Signal Strength Indicator (RSSI), Reference Received Power (RSRP), Reference Received Quality (RSRQ), Layer 1 Signal-to-Interference-plus-Noise Ratio (L1-SINR), Channel Quality Information (CQI), or Pre-decoding Matrix Indicator (PMI). The time window for channel measurements can be a time window with a start offset, or a time window with periodicity and a start offset for periodic measurements. The time unit can be ms, subframes, time slots, or symbols, and the associated subcarrier spacing. Control signaling 240 can be an RRC message, a MAC-CE message, or a DCI message. Network entity 105-a can be configured for periodic, semi-persistent, or aperiodic reporting of channel measurements, and network entity 105-a can be configured for event-triggered reporting of channel measurements (e.g., due to a measurement exceeding a certain threshold). For example, NCR 205 may send channel measurements 245 associated with one or more subbands to network entity 105-a. In some cases, NCR-MT 210 may send channel measurements to network entity 105-a via control link 220. Network entity 105-a may send signaling 250 based on the channel measurements, and NCR 205 may relay signaling 250 based on the channel measurements.

[0078] In some cases, network entity 105-a may use various techniques, such as implementing artificial intelligence (AI) and / or machine learning (ML) techniques, to determine which subbands should be configured for channel measurements on the backhaul link 225 of the NCR-Fwd 215. In some examples, network entity 105-a may use AI and / or ML techniques to transmit signaling 250 based on channel measurements. Additionally, the NCR 205 may use AI and / or ML techniques to relay signaling based on channel measurements.

[0079] In some examples, network entity 105-a may adjust scheduling decisions for UE 115-a (or other remote UEs) based on subband-based channel feedback from backhaul link 225. Scheduling decisions made by network entity 105-a for UE 115-a may include the configuration of bandwidth portions of UE 115-a, frequency domain resource selection for end-to-end channel measurements and / or communications, and imposing upper limits on modulation and decoding schemes (MCS). For example, network entity 105-a may configure (e.g., select) bandwidth portions with sufficient quality for relaying. In some cases, network entity 105-a may adjust the transmit power of the signal based on backhaul link 225 channel feedback to avoid PA saturation at NCR 205.

[0080] In some examples, network entity 105-a may indicate subband-based control information to NCR 205 based on subband-based channel feedback from backhaul link 225. For example, NCR 205 may receive control signaling 255 from network entity 105-a based on channel measurements, which indicates control information associated with forwarding via network control through one or more subbands. Control signaling 255 may be carried by one or more of RRC, MAC-CE, or DCI. NCR 205 may apply different control information on different subbands of the forwarding path. Subband-based control information may include one or more of the following: amplification gain, transmit power, upper limits on amplification gain or transmit power, switching operation, backhaul beam, access link beam, number of receive or transmit antenna elements, or one or more subbands associated with the indicated control information.

[0081] In some examples, the NCR 205 can measure other frequencies in the intermediate frequency (IF) domain or the radio frequency (RF) domain. For example, the NCR 205 can measure total received power, such as RSSI, in the RF or IF domain. Measurements in the RF and IF domains may not be supported by UE 115-a and may be suitable for simple analog NCRs with very limited baseband processing capabilities. In another example, the NCR-MT 210 can be used as a powerful network node and is capable of deriving and reporting more detailed metrics, such as PMI and CQI on non-serving frequencies. In some cases, UE 115-a may not be able to derive and report PMI and CQI on non-serving frequencies.

[0082] In some examples, when network entity 105-a indicates a subband to be used for an upcoming scheduled forwarding operation, the indicated subband information can be used by NCR 205 to adjust the amplification gain associated with the scheduled forwarding operation. For example, NCR 205 can measure the channel strength (or peak-to-average power ratio (PAPR)) of the subband, and NCR can autonomously adjust the amplification gain to a better state to avoid PA saturation. NCR 205 can perform wideband forwarding, and NCR 205 may not have filtering capabilities. In some cases, when network entity 105-a indicates a subband to be used for an upcoming scheduled forwarding operation, NCR 205 can perform new measurements and update the frequency selectivity measurement database.

[0083] Figure 3 Examples of process flow 300 supporting techniques for determining channel measurements by NCR, according to one or more aspects of this disclosure, are shown. In some examples, process flow 300 may be implemented as described in reference respectively. Figure 1 and Figure 2 The described aspects of the wireless communication systems 100 and 200, or those implemented therein. For example, process flow 300 can be implemented by network entity 105-b, which can be as described in reference... Figure 1 and Figure 2 An example of network entity 105 as described. Process flow 300 can be implemented by NCR205-a, which can be as shown in the reference. Figure 2 An example of the described NCR.

[0084] In some examples, the operations illustrated in process flow 300 may be performed by hardware (e.g., including circuits, processing blocks, logic components, and other components), code (e.g., software executed by a processor), or any combination thereof. Alternative examples are possible, some of which may be performed in a different order than described or not at all. In some cases, steps may include additional features not mentioned below, or additional steps may be added.

[0085] At 305, NCR 205-a may receive first control signaling from network entity 105-b via the serving cell associated with NCR 205-a. This first control information indicates one or more subbands for channel measurements on component carriers associated with forwarding for network control. These one or more subbands may not at least partially overlap with the frequency range associated with the serving cell. In some examples, these one or more subbands may be a frequency range, a radio frequency band, a component carrier, or a bandwidth portion of a component carrier. In some examples, the component carriers associated with these one or more subbands may not be configured as the serving cell of NCR 205-a (e.g., NCR 205-a may be configured with a single serving cell and may not be configured with secondary cells (SCells) associated with these one or more subbands). In some examples, the channel measurement may be a received signal strength indicator in the intermediate frequency domain or the radio frequency domain. In some cases, the channel measurement may be a pre-decoding matrix indicator or a channel quality indicator.

[0086] At 310, NCR 205-a can send channel measurements associated with one or more subbands to network entity 105-b based on the receipt of the first control signaling.

[0087] At 315, network entity 105-b can output signaling on one or more subbands based on transmission channel measurements. In some examples, network entity 105-b can adjust the transmission power associated with the signaling based on channel measurements.

[0088] At 320, the NCR 205-a can relay signaling on one or more subbands.

[0089] At 325, NCR 205-a can receive a second control signaling from network entity 105-b based on channel measurements. This second control signaling indicates control information associated with forwarding via network control through one or more subbands. In some examples, the control information may indicate amplification gain, transmit power, switching operation, one or more return beams, one or more access link beams, the number of antenna elements, or a combination thereof.

[0090] At 330, NCR 205-a can receive third control signaling from network entity 105-b based on channel measurements. This third control signaling indicates one or more subbands associated with a scheduled forwarding operation.

[0091] At 335, the NCR 205-a can adjust the amplification gain associated with the scheduled forwarding operation.

[0092] At 340, network entity 105-b may output a third control signaling to the UE based on channel measurements and forwarded via network control. This third control signaling indicates the configuration of frequency domain resources associated with the second channel measurements or with communications.

For example, data, instructions, commands, information, signals, bits, symbols, and chips mentioned throughout the description can be represented by voltage, current, electromagnetic waves, magnetic fields or magnetic particles, light fields or optical particles, or any combination thereof.

[0191] The various exemplary blocks and components described herein can be implemented or performed using a general-purpose processor, DSP, ASIC, CPU, FPGA or other programmable logic device, discrete gate or transistor logic unit, discrete hardware component, or any combination thereof, designed to perform the functions described herein. A general-purpose processor may be a microprocessor, but in alternative embodiments, a processor may be any processor, controller, microcontroller, or state machine. A processor may also be implemented as a combination of computing devices (e.g., a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors combined with a DSP core, or any other such configuration). Any function or operation described herein that can be performed by a processor may be performed by multiple processors capable of performing the described functions or operations individually or jointly.

When implemented using software executed by a processor, the functions can be stored as one or more instructions or code on a computer-readable medium or transmitted using one or more instructions or code on a computer-readable medium. Other examples and specific implementations are within the scope of this disclosure and the appended claims. For example, due to the nature of software, the functions described herein can be implemented using software executed by a processor, hardware, firmware, hardwiring, or any combination of these. Features implementing the functions can also be physically located in various locations, including portions distributed such that the functions are implemented in different physical locations.

[0193] Computer-readable media includes both non-transitory computer storage media and communication media, encompassing any medium that facilitates the transfer of a computer program from one location to another. Non-transitory storage media can be any available medium accessible by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transitory computer-readable media may include RAM, ROM, electrically erasable programmable ROM (EEPROM), flash memory, compressed optical disc (CD) ROM or other optical disc storage devices, magnetic disk storage devices or other magnetic storage devices, or any other non-transitory medium that can be used to carry or store desired program code components in the form of instructions or data structures, and accessible by a general-purpose or special-purpose computer or a general-purpose or special-purpose processor. Furthermore, any connection is appropriately referred to as computer-readable media. For example, if software is transmitted from a website, server, or other remote source using coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL), or wireless technologies such as infrared, radio, and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL, or wireless technologies such as infrared, radio, and microwave are included within the definition of computer-readable media.

[0194] As used herein, the word "or" in a list of items (e.g., a list of items accompanied by phrases such as "at least one of" or "one or more of") in the claims indicates an inclusive list, such that a list of at least one of, for example, A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Furthermore, as used herein, the phrase "based on" should not be construed as a reference to a closed set of conditions. For example, an example step described as "based on condition A" could be based on both condition A and condition B without departing from the scope of this disclosure. In other words, as used herein, the phrase "based on" should be interpreted in the same manner as the phrase "at least partially based on".

[0195] As used herein, including in claims, the article “a” preceding a noun is open-ended and is understood to refer to “at least one” or “one or more” of those nouns. Therefore, the terms “a,” “at least one,” “one or more,” and “at least one of one or more” are interchangeable. For example, where a claim enumerates “components” performing one or more functions, each of the individual functions may be performed by a single component or by any combination of multiple components. Thus, the term “component” having a characteristic or performing a function may refer to “at least one of one or more components” having a particular characteristic or performing a particular function. Subsequent references to a component introduced with the article “a” using the terms “the” or “the” can refer to any or all of the one or more components. For example, a component introduced with the article “a” can be understood to mean “one or more components,” and subsequent reference to “the component” in a claim can be understood as equivalent to referring to “at least one of the one or more components.” Similarly, subsequent references to a component introduced with the terms “the” or “the” as “one or more components” can refer to any or all of the one or more components. For example, reference to "the one or more components" in the subsequent claims can be understood as equivalent to reference to "at least one of the one or more components".

[0196] The term "determine" encompasses a variety of actions, and therefore, "determine" can include calculation, computation, processing, derivation, investigation, lookup (such as by searching in a table, database, or other data structure), identification, and similar actions. Furthermore, "determine" can include receiving (e.g., receiving information), accessing (e.g., accessing data stored in memory), etc. Moreover, "determine" can include parsing, acquiring, selecting, choosing, creating, and other similar actions.

[0197] In the accompanying drawings, similar components or features may have the same reference numerals. Furthermore, various components of the same type can be distinguished by adding a dash after the reference numerals and a second reference numeral for differentiation between similar components. If only the first reference numeral is used in the specification, the description can be applied to any component among similar components having the same first reference numeral, regardless of the second or other subsequent reference numerals.

[0198] The description herein, illustrated with reference to the accompanying drawings, describes an example configuration and does not represent all achievable examples or those within the scope of the claims. The term "example" as used herein means "serving as an example, instance, or illustration," not "preferred" or "advantageous over other examples." The detailed description includes specific details used to provide an understanding of the described techniques. However, these techniques can be practiced without these specific details. In some instances, known structures and devices are shown in block diagram form to avoid obscuring the concept of the described examples.

[0199] The description herein is provided to enable those skilled in the art to implement or use this disclosure. Various modifications to this disclosure will be apparent to those skilled in the art, and the general principles defined herein may be applied to other variations without departing from the scope of this disclosure. Therefore, this disclosure is not limited to the examples and designs described herein, but should be granted the widest scope consistent with the principles and novel features disclosed herein.
